Height is easily implemented by recursion, take the maximum of the height of the subtrees plus one.
The "balance factor of R" refers to the right subtree of the tree which is out of balance, I suppose.
There is a simple solution to this problem using this library. I store an instance of the CallRecord class in MyService.class. When the service is first initialized, the following code is executed:
public class MyService extends Service {
public static CallRecord callRecord;
@Override
public void onCreate() {
super.onCreate();
callRecord = new CallRecord.Builder(this)
.setRecordFileName("test")
.setRecordDirName("Download")
.setRecordDirPath(Environment.getExternalStorageDirectory().getPath()) // optional & default value
.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB) // optional & default value
.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB) // optional & default value
.setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION) // optional & default value
.setShowSeed(false) // optional, default=true ->Ex: RecordFileName_incoming.amr || RecordFileName_outgoing.amr
.build();
callRecord.enableSaveFile();
callRecord.startCallReceiver();
}
@Override
public void onDestroy() {
super.onDestroy();
callRecord.stopCallReceiver();
}
}
Next, do not forget to specify permissions in the manifest. (I may have some extras here, but keep in mind that some of them are necessary only for newer versions of Android)
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.PROCESS_INCOMING_CALLS" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Also it is crucial to request some permissions at the first start of the application. A guide is provided here.

Sometimes, XCode does not forget the line which had an "Editor Placeholder" even if you have replaced it with a value. Cut the portion of the code where XCode is complaining and paste the code back to the same place to make the error message go away. This worked for me.

UPDATE as of angularjs 1.2, the way animations work has changed drastically, most of it is now controlled with CSS, without having to setup javascript callbacks, etc.. You can check the updated tutorial on Year Of Moo. @dfsq pointed out in the comments a nice set of examples.
Roughly you can do it like that :
try
{
//do something
}
catch (Exception ex)
{
string script = "<script>alert('" + ex.Message + "');</script>";
if (!Page.IsStartupScriptRegistered("myErrorScript"))
{
Page.ClientScript.RegisterStartupScript("myErrorScript", script);
}
}
But I recommend you to define your custom Exception and throw it anywhere you need. At your page catch this custom exception and register your message box script.
To push up through a given commit, you can write:
git push <remotename> <commit SHA>:<remotebranchname>
provided <remotebranchname>
already exists on the remote. (If it doesn't, you can use git push <remotename> <commit SHA>:refs/heads/<remotebranchname>
to autocreate it.)
If you want to push a commit without pushing previous commits, you should first use git rebase -i
to re-order the commits.
ImageView imageView=findViewById(R.id.imageView)
if you have image in drawable folder then use
imageView.setImageResource(R.drawable.imageView)
if you have uri and want to display it in imageView then use
imageView.setImageUri("uri")
if you have bitmap and want to display it in imageView then use
imageView.setImageBitmap(bitmap)
note:- 1. imageView.setImageDrawable()
is now deprecated in java
2. If image uri is from firebase or from any other online link then use
Picasso.get()
.load("uri")
.into(imageView)
(https://github.com/square/picasso)
or use
Glide.with(context)
.load("uri")
.into(imageView)
I have a generous amount of data that's stored in my repo as individual JSON fragments. There's about 75,000 files sitting under a few directories and it's not really detrimental to performance.
Checking them in the first time was, obviously, a little slow.
here's a regex one for ya.
update table
set col1=null
where col1 not like '%[a-z,0-9]%'
essentially finds any columns that dont have letters or numbers in them and sets it to null. might have to update if you have columns with just special characters.
Just wanted to add another solution to this question. This implementation works for my scenario, where CaliBurn is responsible for displaying the main Window.
protected override void OnStartup(object sender, StartupEventArgs e)
{
DisplayRootViewFor<IMainWindowViewModel>();
Application.MainWindow.Topmost = true;
Application.MainWindow.Activate();
Application.MainWindow.Activated += OnMainWindowActivated;
}
private static void OnMainWindowActivated(object sender, EventArgs e)
{
var window = sender as Window;
if (window != null)
{
window.Activated -= OnMainWindowActivated;
window.Topmost = false;
window.Focus();
}
}
Explicitly checking for NULL could provide a hint to the compiler on what you are trying to do, ergo leading to being less error-prone.
Comparator
provides a way for you to provide custom comparison logic for types that you have no control over.
Comparable
allows you to specify how objects that you are implementing get compared.
Obviously, if you don't have control over a class (or you want to provide multiple ways to compare objects that you do have control over) then use Comparator
.
Otherwise you can use Comparable
.
eof() checks the eofbit in the stream state.
On each read operation, if the position is at the end of stream and more data has to be read, eofbit is set to true. Therefore you're going to get an extra character before you get eofbit=1.
The correct way is to check whether the eof was reached (or, whether the read operation succeeded) after the reading operation. This is what your second version does - you do a read operation, and then use the resulting stream object reference (which >> returns) as a boolean value, which results in check for fail().

Two more useful commands:
To change the default FTP upload folder
Step 1:
edit /etc/vsftpd/vsftpd.conf
Step 2: Create a new entry at the bottom of the page:

To apply read, write, delete permission to the files under folder so that you can manage using a FTP device
find /var/www/html -type d -exec chmod 777 {} \;
If your YAML file looks like this:
# tree format
treeroot:
branch1:
name: Node 1
branch1-1:
name: Node 1-1
branch2:
name: Node 2
branch2-1:
name: Node 2-1
And you've installed PyYAML
like this:
pip install PyYAML
And the Python code looks like this:
import yaml
with open('tree.yaml') as f:
# use safe_load instead load
dataMap = yaml.safe_load(f)
The variable dataMap
now contains a dictionary with the tree data. If you print dataMap
using PrettyPrint, you will get something like:
{
'treeroot': {
'branch1': {
'branch1-1': {
'name': 'Node 1-1'
},
'name': 'Node 1'
},
'branch2': {
'branch2-1': {
'name': 'Node 2-1'
},
'name': 'Node 2'
}
}
}
So, now we have seen how to get data into our Python program. Saving data is just as easy:
with open('newtree.yaml', "w") as f:
yaml.dump(dataMap, f)
You have a dictionary, and now you have to convert it to a Python object:
class Struct:
def __init__(self, **entries):
self.__dict__.update(entries)
Then you can use:
>>> args = your YAML dictionary
>>> s = Struct(**args)
>>> s
<__main__.Struct instance at 0x01D6A738>
>>> s...
and follow "Convert Python dict to object".
For more information you can look at pyyaml.org and this.

An easy, loop-free alternative is to use the horizontalalignment
Text property as a keyword argument to xticks
[1]. In the below, at the commented line, I've forced the xticks
alignment to be "right".
n=5
x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Long ticklabel %i' % i for i in range(n)]
fig, ax = plt.subplots()
ax.plot(x,y, 'o-')
plt.xticks(
[0,1,2,3,4],
["this label extends way past the figure's left boundary",
"bad motorfinger", "green", "in the age of octopus diplomacy", "x"],
rotation=45,
horizontalalignment="right") # here
plt.show()
(yticks
already aligns the right edge with the tick by default, but for xticks
the default appears to be "center".)
[1] You find that described in the xticks documentation if you search for the phrase "Text properties".
Instead of parsing this from proc, one can use functions like getrusage() or clock_gettime() and calculate the cpu usage as a ratio or wallclock time and time the process/thread used on the cpu.
While only a few lines are required to plot multiple/overlapping histograms in ggplot2, the results are't always satisfactory. There needs to be proper use of borders and coloring to ensure the eye can differentiate between histograms.
The following functions balance border colors, opacities, and superimposed density plots to enable the viewer to differentiate among distributions.
Single histogram:
plot_histogram <- function(df, feature) {
plt <- ggplot(df, aes(x=eval(parse(text=feature)))) +
geom_histogram(aes(y = ..density..), alpha=0.7, fill="#33AADE", color="black") +
geom_density(alpha=0.3, fill="red") +
geom_vline(aes(xintercept=mean(eval(parse(text=feature)))), color="black", linetype="dashed", size=1) +
labs(x=feature, y = "Density")
print(plt)
}
Multiple histogram:
plot_multi_histogram <- function(df, feature, label_column) {
plt <- ggplot(df, aes(x=eval(parse(text=feature)), fill=eval(parse(text=label_column)))) +
geom_histogram(alpha=0.7, position="identity", aes(y = ..density..), color="black") +
geom_density(alpha=0.7) +
geom_vline(aes(xintercept=mean(eval(parse(text=feature)))), color="black", linetype="dashed", size=1) +
labs(x=feature, y = "Density")
plt + guides(fill=guide_legend(title=label_column))
}
Usage:
Simply pass your data frame into the above functions along with desired arguments:
plot_histogram(iris, 'Sepal.Width')
plot_multi_histogram(iris, 'Sepal.Width', 'Species')
The extra parameter in plot_multi_histogram is the name of the column containing the category labels.
We can see this more dramatically by creating a dataframe with many different distribution means:
a <-data.frame(n=rnorm(1000, mean = 1), category=rep('A', 1000))
b <-data.frame(n=rnorm(1000, mean = 2), category=rep('B', 1000))
c <-data.frame(n=rnorm(1000, mean = 3), category=rep('C', 1000))
d <-data.frame(n=rnorm(1000, mean = 4), category=rep('D', 1000))
e <-data.frame(n=rnorm(1000, mean = 5), category=rep('E', 1000))
f <-data.frame(n=rnorm(1000, mean = 6), category=rep('F', 1000))
many_distros <- do.call('rbind', list(a,b,c,d,e,f))
Passing data frame in as before (and widening chart using options):
options(repr.plot.width = 20, repr.plot.height = 8)
plot_multi_histogram(many_distros, 'n', 'category')

Looking at the documentation for JSON, it seems that the regex can simply be three parts if the goal is just to check for fitness:
[]
or {}
[{\[]{1}
...[}\]]{1}
[,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]
...""
".*?"
...All together:
[{\[]{1}([,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]|".*?")+[}\]]{1}
If the JSON string contains newline
characters, then you should use the singleline
switch on your regex flavor so that .
matches newline
. Please note that this will not fail on all bad JSON, but it will fail if the basic JSON structure is invalid, which is a straight-forward way to do a basic sanity validation before passing it to a parser.
ngStyle

Recently, when I was dealing with an AJAX application/RIA, I was having the same issue! And I used implicit wait, with a time of around 90 seconds. It waits, till the element is available...So, what we can do to make sure, that page gets loaded completely is,
add a boolean statement, checking for whether the condition(a particular part of the element), is present and assign it to a variable, check for the condition and only when it is true, " do the necessary actions!"...In this way, I figured out, both waits could be used...
Ex:
@Before
{ implicit wait statement}
@Test
{
boolean tr1=Driver.findElement(By.xpath("xx")).isEnabled/isDisplayed;
if (tr1==true && ____)//as many conditions, to make sure, the page is loaded
{
//do the necessary set of actions...
driver.findElement(By.xpath("yy")).click();
}
}
Hope this helps!! It is in implementation stage, for me too...

The correct way to create a user in Django is to use the create_user function. This will handle the hashing of the password, etc..

password='glass onion')
Depends in how you are hiding your div, diplay=none
is different of visibility=hidden
and the opacity=0
Visibility then use ...style.visibility='visible'
Display then use ...style.display='block'
(or others depends how
you setup ur css, inline, inline-block, flex...)
Opacity then use ...style.opacity='1';

You can also use Ghostscript to merge different PDFs. You can even use it to merge a mix of PDFs, PostScript (PS) and EPS into one single output PDF file:
gs \
-o merged.pdf \
-sDEVICE=pdfwrite \
-dPDFSETTINGS=/prepress \
input_1.pdf \
input_2.pdf \
input_3.eps \
input_4.ps \
input_5.pdf
However, I agree with other answers: for your use case of merging PDF file types only, pdftk
may be the best (and certainly fastest) option.
Update:
If processing time is not the main concern, but if the main concern is file size (or a fine-grained control over certain features of the output file), then the Ghostscript way certainly offers more power to you. To highlight a few of the differences:
The code for specific digits after decimals is:
var a = 1.543240952039
var roundedString = String(format: "%.3f", a)
Here the %.3f tells the swift to make this number rounded to 3 decimal places.and if you want double number, you may use this code:
// String to Double
var roundedString = Double(String(format: "%.3f", b))
I have also been through this problem,
First i tried setting my password of root to blank using command :
SET PASSWORD FOR root@localhost=PASSWORD('');
But don't be happy , PHPMYADMIN uses 127.0.0.1 not localhost , i know you would say both are same but that is not the case , use the command mentioned underneath and you are done.
SET PASSWORD FOR [email protected]=PASSWORD('');
Just replace localhost with 127.0.0.1 and you are done .

This is the solution for my issue..... Thanks everyone for the valuable answers.......
My requirement was to keep the password in a config file in encrypted form and decrypt when the program runs. For this I used the jasypt
library (jasypt-1.9.3.jar
). This is a very good library and we can accomplish the task with just 4 lines of code.
First, after adding jar to my project I imported the below library.
import org.jasypt.util.text.AES256TextEncryptor;
Then I created the below method. I then called this method by passing the text which I need to encrypt in password
parameter. Using aesEncryptor.encrypt
method, I encrypted the password which is stored to the myEncryptedPassword
variable.
public void EncryptPassword(String password)
{
AES256TextEncryptor aesEncryptor = new AES256TextEncryptor();
aesEncryptor.setPassword("mypassword");
String myEncryptedPassword = aesEncryptor.encrypt(password);
System.out.println(myEncryptedPassword );
}
You might have noticed the method setPassword
method and the value mypassword
is used in the above code. This is to make sure that no one can decrypt the password even if they use the encrypted password using the same library.
Now I can see the value in the myEncryptedPassword
variable something like h9oJ4P5P8ToRy38wvK11PUQCBrT1oH/zbMWuMrbOlI0rfZrj+qSg6f/u0jctOs/ZUf9t3shiwnEt05/nq8bnag==
. This is the encrypted password. Keep this value in the config file.
I then created the below method to decrypt the password to be used in my program. The value of passwordFromConfigFile
is the encrypted text which I got from the EncryptPassword
method. Note that you have to use the same password in the aesEncryptor.setPassword
method that you used to encrypt the password.
public String DecryptPassword(String passwordFromConfigFile)
{
AES256TextEncryptor aesEncryptor = new AES256TextEncryptor();
aesEncryptor.setPassword("mypassword");
String decryptedPassword = aesEncryptor.decrypt(passwordFromConfigFile);
return decryptedPassword;
}
The variable decryptedPassword
will now have the decrypted password value.
grep -nr "search string" directory
This gives you the line with the line number.
Try this:
>>> f = open('goodlines.txt')
>>> mylist = f.readlines()
open()
function returns a file object. And for file object, there is no method like splitlines()
or split()
. You could use dir(f)
to see all the methods of file object.
From here:
Beginning with Android 3.0 (API level 11), all activities that use the default theme have an ActionBar as an app bar. However, app bar features have gradually been added to the native ActionBar over various Android releases. As a result, the native ActionBar behaves differently depending on what version of the Android system a device may be using. By contrast, the most recent features are added to the support library's version of Toolbar, and they are available on any device that can use the support library.
So one option is to disable ActionBar completely (in the app manifest.xml file) and then add Toolbar in every page that needs an ActionBar.

If using ES2016 you can use async
and await
and do something like:
(async () => {
const data = await fetch(url)
myFunc(data)
}())
If using ES2015 you can use Generators. If you don't like the syntax you can abstract it away using an async
utility function as explained here.
If using ES5 you'll probably want a library like Bluebird to give you more control.
Finally, if your runtime supports ES2015 already execution order may be preserved with parallelism using Fetch Injection.
Adding to what @Shog9 posted, you can also restrict dates individually in the beforeShowDay: callback function.
You supply a function that takes a date and returns a boolean array:
"$(".selector").datepicker({ beforeShowDay: nationalDays})
natDays = [[1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'], [4, 27, 'za'],
[5, 25, 'ar'], [6, 6, 'se'], [7, 4, 'us'], [8, 17, 'id'], [9, 7,
'br'], [10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke']];
function nationalDays(date) {
for (i = 0; i < natDays.length; i++) {
if (date.getMonth() == natDays[i][0] - 1 && date.getDate() ==
natDays[i][1]) {
return [false, natDays[i][2] + '_day'];
}
}
return [true, ''];
}

I was using {{myFunction()}}
in the template but then found another way here using $timeout
inside the controller. Thought I'd share it, works great for me.
angular.module('myApp').controller('myCtrl', ['$timeout',
function($timeout) {
var self = this;
self.controllerFunction = function () { alert('controller function');}
$timeout(function () {
var vanillaFunction = function () { alert('vanilla function'); }();
self.controllerFunction();
});
}]);
boolean a = (x < z) && (x == x);
This kind will short-circuit, meaning if (x < z)
evaluates to false then the latter is not evaluated, a
will be false, otherwise &&
will also evaluate (x == x)
.
&
is a bitwise operator, but also a boolean AND operator which does not short-circuit.
You can test them by something as follows (see how many times the method is called in each case):
public static boolean getFalse() {
System.out.println("Method");
return false;
}
public static void main(String[] args) {
if(getFalse() && getFalse()) { }
System.out.println("=============================");
if(getFalse() & getFalse()) { }
}
options = $("#span_id>select>option[value='"+i+"']");
option = options.text();
alert(option);

You could use the :first-child
and :last-child
pseudo-selectors:
tr td:first-child,
tr td:last-child {
/* styles */
}
This should work in all major browsers, but IE7 has some problems when elements are added dynamically (and it won't work in IE6).
If you want to gain access to the whole the error body, do it as shown below:
async function login(reqBody) {
try {
let res = await Axios({
method: 'post',
url: 'https://myApi.com/path/to/endpoint',
data: reqBody
});
let data = res.data;
return data;
} catch (error) {
console.log(error.response); // this is the main part. Use the response property from the error object
return error.response;
}
}
If you do this programatically and not in web.config its:
new WebHttpBinding(WebHttpSecurityMode.Transport)
I run into this a bit working with legacy stuff where they only work on east coast US and don't store dates in UTC, it's all EST. I have to filter on the dates based on user input in the browser so must pass the date in local time in JSON format.
Just to elaborate on this solution already posted - this is what I use:
// Could be picked by user in date picker - local JS date
date = new Date();
// Create new Date from milliseconds of user input date (date.getTime() returns milliseconds)
// Subtract milliseconds that will be offset by toJSON before calling it
new Date(date.getTime() - (date.getTimezoneOffset() * 60000)).toJSON();
So my understanding is this will go ahead and subtract time (in milliseconds (hence 60000) from the starting date based on the timezone offset (returns minutes) - in anticipation for the addition of time toJSON() is going to add.
Use android vollley, it is very fast and you can betterm manipulate requests. Send post request using Volley and receive in PHP
Basically, you will create a map with key-value params for the php request(POST/GET), the php will do the desired processing and you will return the data as JSON(json_encode()). Then you can either parse the JSON as needed or use GSON from Google to let it do the parsing.
You can't access the overflow flag from C/C++.
Some compilers allow you to insert trap instructions into the code. On GCC the option is -ftrapv
.
The only portable and compiler independent thing you can do is to check for overflows on your own. Just like you did in your example.
However, -ftrapv
seems to do nothing on x86 using the latest GCC. I guess it's a leftover from an old version or specific to some other architecture. I had expected the compiler to insert an INTO opcode after each addition. Unfortunately it does not do this.
I found a solution to this. It's bloody witchcraft, but it works.
When you install the client, open Control Panel > Network Connections.
You'll see a disabled network connection that was added by the TAP installer (Local Area Connection 3 or some such).
Right Click it, click Enable.
The device will not reset itself to enabled, but that's ok; try connecting w/ the client again. It'll work.
queryForMap
is appropriate if you want to get a single row. You are selecting without a where
clause, so you probably want to queryForList
. The error is probably indicative of the fact that queryForMap
wants one row, but you query is retrieving many rows.
Check out the docs. There is a queryForList
that takes just sql; the return type is a
List<Map<String,Object>>
.
So once you have the results, you can do what you are doing. I would do something like
List results = template.queryForList(sql);
for (Map m : results){
m.get('userid');
m.get('username');
}
I'll let you fill in the details, but I would not iterate over keys in this case. I like to explicit about what I am expecting.
If you have a User
object, and you actually want to load User instances, you can use the queryForList
that takes sql and a class type
queryForList(String sql, Class<T> elementType)
(wow Spring has changed a lot since I left Javaland.)
If you want to see which IP addresses are in use on a specific subnet then there are several different IP Address managers.

Ignacio Vazquez-Abrams is correct. But to elaborate, re.match()
will return either None
, which evaluates to False
, or a match object, which will always be True
as he said. Only if you want information about the part(s) that matched your regular expression do you need to check out the contents of the match object.
You can create a setTimeout
loop using recursion:
function timeout() {
setTimeout(function () {
// Do Something Here
// Then recall the parent function to
// create a recursive loop.
timeout();
}, 1000);
}
The problem with setInterval()
and setTimeout()
is that there is no guarantee your code will run in the specified time. By using setTimeout()
and calling it recursively, you're ensuring that all previous operations inside the timeout are complete before the next iteration of the code begins.
I had similar problems. The one downside is that with cin.ignore()
, you have to press enter 1 more time, which messes with the program.
This likely doesn't work with start
, as that starts a new window, but to answer your question:
If the command returns a error level you can check the following ways
By Specific Error Level
commandhere
if %errorlevel%==131 echo do something
By If Any Error
commandhere || echo what to do if error level ISN'T 0
By If No Error
commandhere && echo what to do if error level IS 0
If it does not return a error level but does give output, you can catch it in a variable and determine by the output, example (note the tokens and delims are just examples and would likely fail with any special characters)
By Parsing Full Output
for /f "tokens=* delims=" %%a in ('somecommand') do set output=%%a
if %output%==whateveritwouldsayinerror echo error
Or you could just look for a single phrase in the output like the word Error
By Checking For String
commandhere | find "Error" || echo There was no error!
commandhere | find "Error" && echo There was an error!
And you could even mix together (just remember to escape |
with ^|
if in a for
statement)
Hope this helps.
If you are looking out at performance, you could have a look at the java.nio.*

Make Executable your jar and after that double click on it on Mac OS then it works successfully.

If you're using AMD modules, the other answers won't work in TypeScript 1.0 (the newest at the time of writing.)
You have different approaches available to you, depending upon how many things you wish to export from each .ts
file.
Foo.ts
export class Foo {}
export interface IFoo {}
Bar.ts
import fooModule = require("Foo");
var foo1 = new fooModule.Foo();
var foo2: fooModule.IFoo = {};
Foo.ts
class Foo
{}
export = Foo;
Bar.ts
import Foo = require("Foo");
var foo = new Foo();
Here is another concrete example.It is for a shared library. The shared library's main function is to communicate with a smart card reader. But it can also receive 'configuration information' at runtime over udp. The udp is handled by a thread which MUST be started at init time.
__attribute__((constructor)) static void startUdpReceiveThread (void) {
pthread_create( &tid_udpthread, NULL, __feigh_udp_receive_loop, NULL );
return;
}
The library was written in c.
You can use literals, it's more compact.
NSString* myString = [@(17) stringValue];
(Boxes as a NSNumber and uses its stringValue method)
using date method, we should be able to get the result. ie; date('N/D/l', mktime(0, 0, 0, month, day, year));
For Example
echo date('N', mktime(0, 0, 0, 7, 1, 2017)); // will return 6
echo date('D', mktime(0, 0, 0, 7, 1, 2017)); // will return Sat
echo date('l', mktime(0, 0, 0, 7, 1, 2017)); // will return Saturday
In 2018, I think this is the best way; that supports IE9+ and modern browsers.
UPDATE: See this test and repo for comparison on different implementations.
function CustomError(message) {
Object.defineProperty(this, 'name', {

if (Error.hasOwnProperty('captureStackTrace')) { // V8
Error.captureStackTrace(this, CustomError);
} else {

Object.setPrototypeOf(CustomError.prototype, Error.prototype);
} else {
CustomError.prototype = Object.create(Error.prototype, {

Also beware that __proto__
property is deprecated which is widely used in other answers.
The following function will allow differentiating between empty strings and undefined cookies. Undefined cookies will correctly return undefined
and not an empty string unlike some of the other answers here.
function getCookie(name) {
return (document.cookie.match('(^|;) *'+name+'=([^;]*)')||[])[2];
}
The above worked fine for me on all browsers I checked, but as mentioned by @vanovm in comments, as per the specification the key/value may be surrounded by whitespace. Hence the following is more standard compliant.
function getCookie(name) {
return (document.cookie.match('(?:^|;)\\s*'+name.trim()+'\\s*=\\s*([^;]*?)\\s*(?:;|$)')||[])[1];
}
DECLARE @StartDate DATETIME, @EndDate DATETIME
SET @StartDate = DATEADD(mm, DATEDIFF(mm, 0, getdate()) - 1, 0)
SET @EndDate = dateadd(dd, -1, DATEADD(mm, 1, @StartDate))
SELECT * FROM Member WHERE date_created BETWEEN @StartDate AND @EndDate
and another upgrade to mrdenny's solution.
It gives the exact last day of the previous month as well.

Here's stored procedure, which will generate the table based on data from one table and column and data from other table and column.
The function 'sum(if(col = value, 1,0)) as value ' is used. You can choose from different functions like MAX(if()) etc.

The code posted in the question is obviously not a a complete example (it's not adding anything to the arraylist, it's not defining i
anywhere).
First as others have said you need to understand the difference between primitive types and the class types that box them. E.g. Integer
boxes int
, Double
boxes double
, Long
boxes long
and so-on. Java automatically boxes and unboxes in various scenarios (it used to be you had to box and unbox manually with library calls but that was deemed an ugly PITA).
http://docs.oracle.com/javase/tutorial/java/data/autoboxing.html
You can mostly cast from one primitive type to another (the exception being boolean
) but you can't do the same for boxed types. To convert one boxed type to another is a bit more complex. Especially if you don't know the box type in advance. Usually it will involve converting via one or more primitive types.
So the answer to your question depends on what is in your arraylist, if it's just objects of type Integer you can do.
sum = ((double)(int)marks.get(i));
The cast to int
will behind the scenes first cast the result of marks.get
to Integer
, then it will unbox that integer. We then use another cast to convert the primitive int
to a primitive double
. Finally the result will be autoboxed back into a Double
when it is assigned to the sum variable. (asside, it would probablly make more sense for sum to be of type double
rather than Double
in most cases).
If your arraylist contains a mixture of types but they all implement the Number
interface (Integer, Short, Long, Float and Double all do but Character and Boolean do not) then you can do.
sum = ((Number)marks.get(i)).doubleValue();
If there are other types in the mix too then you might need to consider using the instanceof
operator to identify them and take appropriate action.
There is no completely portable solution.
Question 19.1 of the comp.lang.c FAQ covers this in some depth, with solutions for Windows, Unix-like systems, and even MS-DOS and VMS.
A quick and incomplete summary:
curses
library; call cbreak()
followed by getch()
(not to be confused with the Windows-specific getch()
function). Note that curses
generally takes control of the terminal, so this is likely to be overkill.ioctl()
to manipulate the terminal settings.tcgetattr()
and tcsetattr()
may be a better solution.system()
to invoke the stty
command.getch()
or getche()
.SMG$
) routines might do the trick.All these C solutions should work equally well in C++; I don't know of any C++-specific solution.
You have an extra -c

A pure RESTful API should use the underlying protocol standard features:
For HTTP, the RESTful API should comply with existing HTTP standard headers. Adding a new HTTP header violates the REST principles. Do not re-invent the wheel, use all the standard features in HTTP/1.1 standards - including status response codes, headers, and so on. RESTFul web services should leverage and rely upon the HTTP standards.
RESTful services MUST be STATELESS. Any tricks, such as token based authentication that attempts to remember the state of previous REST requests on the server violates the REST principles. Again, this is a MUST; that is, if you web server saves any request/response context related information on the server in attempt to establish any sort of session on the server, then your web service is NOT Stateless. And if it is NOT stateless it is NOT RESTFul.
Bottom-line: For authentication/authorization purposes you should use HTTP standard authorization header. That is, you should add the HTTP authorization / authentication header in each subsequent request that needs to be authenticated. The REST API should follow the HTTP Authentication Scheme standards.The specifics of how this header should be formatted are defined in the RFC 2616 HTTP 1.1 standards – section 14.8 Authorization of RFC 2616, and in the RFC 2617 HTTP Authentication: Basic and Digest Access Authentication.
I have developed a RESTful service for the Cisco Prime Performance Manager application. Search Google for the REST API document that I wrote for that application for more details about RESTFul API compliance here. In that implementation, I have chosen to use HTTP "Basic" Authorization scheme. - check out version 1.5 or above of that REST API document, and search for authorization in the document.

The better option is create a new table copy the rows to the destination table, drop the actual table and rename the newly created table . This method is good for small tables,
For Mono(Droid) solutions:
decimal decimalValue = decimal.Parse(input.Text.Replace(",", ".") , CultureInfo.InvariantCulture);
It is possible to use Object.defineProperty()
in order to redefine the 'value' property of the input element and do anything during its changing.
Object.defineProperty()
allows us to define a getter and setter for a property, thus controlling it.
replaceWithWrapper($("#hid1")[0], "value", function(obj, property, value) {
console.log("new value:", value)
});
function replaceWithWrapper(obj, property, callback) {
Object.defineProperty(obj, property, new function() {
var _value = obj[property];
return {
set: function(value) {
_value = value;
callback(obj, property, value)
},
get: function() {
return _value;
}
}
});
}
$("#hid1").val(4);
Use the .str()-method:
Manages the contents of the underlying string object.
1) Returns a copy of the underlying string as if by calling
rdbuf()->str()
.2) Replaces the contents of the underlying string as if by calling
rdbuf()->str(new_str)
...Notes
The copy of the underlying string returned by str is a temporary object that will be destructed at the end of the expression, so directly calling
c_str()
on the result ofstr()
(for example inauto *ptr = out.str().c_str();
) results in a dangling pointer...
Bewaaaaare of Gson! It's very cool, very great, but the second you want to do anything other than simple objects, you could easily need to start building your own serializers (which isn't that hard).
Also, if you have an array of Objects, and you deserialize some json into that array of Objects, the true types are LOST! The full objects won't even be copied! Use XStream.. Which, if using the jsondriver and setting the proper settings, will encode ugly types into the actual json, so that you don't loose anything. A small price to pay (ugly json) for true serialization.
Note that Jackson fixes these issues, and is faster than GSON.
It's hard to respond to a statement without examples of how it's not working, but it's crucial to understand that TFVC (in "Server Workspace" mode, which was the mechanism prior to TFS 2012) does not examine the state of your local filesystem. TFVC Server Workspaces are a "checkout-edit-checkin" type of system where this is by-design, an intentional decision made to massively reduce the amount of file I/O required to determine the state of your workspace. Instead, the workspace information is saved on the server.
This allows TFVC Server Workspaces to scale to very large codebases very efficiently. If you are in a multi-gigabyte code base (like Visual Studio or the Windows source tree) then your client does not need to scan your local filesystem, looking for files that may have changed, because the contract you have with TFS is that you will explicitly check a file out when you want to edit it.
You are expected to not mark a file as write-only and change it without explicitly checking it out first. If you go down this route, then the server does not know that you have made changes to your file, and performing a "Get Latest" operation will not update your local workspace, because you haven't told the server that you've made changes.
If you do subvert this mechanism then you can use the tfpt reconcile
command to examine your local workspace for changes that you have made locally.
If you find yourself using "Get Specific Version" and selecting the "force" and "overwrite" options, then it is very likely that you are in the habit of bypassing all of the enforcements that TFS has implemented to keep you from hurting yourself, and you should probably consider TFVC Local Workspaces.
TFVC Local Workspaces provide an "edit-merge-commit" type of version control system, which means that you do not need to explicitly check files out before editing them and they are not read-only on-disk. Instead, you simply need to edit the file, and your client will scan the filesystem, notice the change, and present this as a pending change.
TFVC Local Workspaces are recommended for small projects that do not require fine-grained permissions control, since they present a much nicer workflow. You are not required to be online, and you do not have to explicitly check files out before editing them.
TFVC Local Workspaces are the default in TFS 2012, and if they are not enabled for you, then you should ask your server administrator. (Organizations with very large codebases or strict auditing requirements may disable TFVC Local Workspaces.)
Eric Sink's excellent book Version Control By Example outlines the differences between checkout-edit-checkin and edit-merge-commit systems and when one is more appropriate than the other.
The Professional Team Foundation Server 2013 book also provides excellent information about the differences between TFVC Server Workspaces and TFVC Local Workspaces. The MSDN documentation and blogs also provide detailed information:

This results in the following (with matplotlib version 2.2.0):
You could hash the GUIDs. That way, you should get a result much faster.
Oh, of course, running multiple threads at the same time is also a good idea, that way you'll increase the chance of a race condition generating the same GUID twice on different threads.
Checking that strings are integers is separate to comparing if one is greater or lesser than another. You should always compare number with number and string with string as the algorithm for dealing with mixed types not easy to remember.
'00100' < '1' // true
as they are both strings so only the first zero of '00100' is compared to '1' and because it's charCode is lower, it evaluates as lower.
However:
'00100' < 1 // false
as the RHS is a number, the LHS is converted to number before the comparision.
A simple integer check is:
function isInt(n) {
return /^[+-]?\d+$/.test(n);
}
It doesn't matter if n is a number or integer, it will be converted to a string before the test.
If you really care about performance, then:
var isInt = (function() {
var re = /^[+-]?\d+$/;
return function(n) {
return re.test(n);
}
}());
Noting that numbers like 1.0 will return false. If you want to count such numbers as integers too, then:
var isInt = (function() {
var re = /^[+-]?\d+$/;
var re2 = /\.0+$/;
return function(n) {
return re.test((''+ n).replace(re2,''));
}
}());
Once that test is passed, converting to number for comparison can use a number of methods. I don't like parseInt() because it will truncate floats to make them look like ints, so all the following will be "equal":
parseInt(2.9) == parseInt('002',10) == parseInt('2wewe')
and so on.
Once numbers are tested as integers, you can use the unary + operator to convert them to numbers in the comparision:
if (isInt(a) && isInt(b)) {
if (+a < +b) {
// a and b are integers and a is less than b
}
}
Other methods are:
Number(a); // liked by some because it's clear what is happening
a * 1 // Not really obvious but it works, I don't like it
Look at the following example code:
public class MyWorker
{
public SharedData state;
public void DoWork(SharedData someData)
{
this.state = someData;
while (true) ;
}
}
public class SharedData {
X myX;
public getX() { etc
public setX(anX) { etc
}
public class Program
{
public static void Main()
{
SharedData data = new SharedDate()
MyWorker work1 = new MyWorker(data);
MyWorker work2 = new MyWorker(data);
Thread thread = new Thread(new ThreadStart(work1.DoWork));
thread.Start();
Thread thread2 = new Thread(new ThreadStart(work2.DoWork));
thread2.Start();
}
}
In this case, the thread class MyWorker
has a variable state
. We initialise it with the same object. Now you can see that the two workers access the same SharedData object. Changes made by one worker are visible to the other.
You have quite a few remaining issues. How does worker 2 know when changes have been made by worker 1 and vice-versa? How do you prevent conflicting changes? Maybe read: this tutorial.
You can use basename()
and $_SERVER['PHP_SELF']
to get current page file name
echo basename($_SERVER['PHP_SELF']); /* Returns The Current PHP File Name */
You'd have to use the Import/Export wizards in SSMS to migrate everything
There is no "downgrade" possible using backup/restore or detach/attach. Therefore what you have to do is:
Are they in the right subdirectories?
If you put /usr/share/stuff
on the class path, files defined with package org.name
should be in /usr/share/stuff/org/name
.
EDIT: If you don't already know this, you should probably read this: http://download.oracle.com/javase/1.5.0/docs/tooldocs/windows/classpath.html#Understanding
EDIT 2: Sorry, I hadn't realised you were talking of Java source files in /usr/share/stuff
. Not only they need to be in the appropriate sub-directory, but you need to compile them. The .java
files don't need to be on the classpath, but on the source path. (The generated .class
files need to be on the classpath.)
You might get away with compiling them if they're not under the right directory structure, but they should be, or it will generate warnings at least. The generated class files will be in the right subdirectories (wherever you've specified -d
if you have).
You should use something like javac -sourcepath .:/usr/share/stuff test.java
, assuming you've put the .java
files that were under /usr/share/stuff
under /usr/share/stuff/org/name
(or whatever is appropriate according to their package names).
Never try to set the compiler in the CMakeLists.txt
file.
See the CMake FAQ about how to use a different compiler:
https://gitlab.kitware.com/cmake/community/wikis/FAQ#how-do-i-use-a-different-compiler
(Note that you are attempting method #3 and the FAQ says "(avoid)"...)
We recommend avoiding the "in the CMakeLists" technique because there are problems with it when a different compiler was used for a first configure, and then the CMakeLists file changes to try setting a different compiler... And because the intent of a CMakeLists file should be to work with multiple compilers, according to the preference of the developer running CMake.
The best method is to set the environment variables CC
and CXX
before calling CMake for the very first time in a build tree.
After CMake detects what compilers to use, it saves them in the CMakeCache.txt
file so that it can still generate proper build systems even if those variables disappear from the environment...
If you ever need to change compilers, you need to start with a fresh build tree.

I had the same issue, but using Angular + DataTable with a fnDrawCallback
+ row grouping + $compiled nested directives. I placed the $timeout in my fnDrawCallback
function to fix pagination rendering.
Before example, based on row_grouping source:
var myDrawCallback = function myDrawCallbackFn(oSettings){
var nTrs = $('table#result>tbody>tr');
for(var i=0; i<nTrs.length; i++){
//1. group rows per row_grouping example
//2. $compile html templates to hook datatable into Angular lifecycle
}
}
After example:
var myDrawCallback = function myDrawCallbackFn(oSettings){
var nTrs = $('table#result>tbody>tr');
$timeout(function requiredRenderTimeoutDelay(){
for(var i=0; i<nTrs.length; i++){
//1. group rows per row_grouping example
//2. $compile html templates to hook datatable into Angular lifecycle
}
,50); //end $timeout
}
Even a short timeout delay was enough to allow Angular to render my compiled Angular directives.
If you do not need to dynamically adjust the size, you have the memory overhead of saving the capacity (one pointer/size_t). That's it.
to convert a TimestampTZ in oracle, you do
TO_TIMESTAMP_TZ('2012-10-09 1:10:21 CST','YYYY-MM-DD HH24:MI:SS TZR')

As a shorthand you can run:
docker tag d58 myname/server:latest
Where d58
represents the first 3 characters of the IMAGE ID,in this case, that's all you need.
Finally, you can remove the old image as follows:
docker rmi server
Not knowing quite what the 'answer' command did, I ran it, much to my dismay. It recursively removes every file from your git repo.
Stackoverflow to the rescue... How to revert a "git rm -r ."?
git reset HEAD
Did the trick, since I had uncommitted local files that I didn't want to overwrite.
The Wikipedia page on it is a good place to start.
To sum up:
float
is represented in 32 bits, with 1 sign bit, 8 bits of exponent, and 23 bits of the significand (or what follows from a scientific-notation number: 2.33728*1012; 33728 is the significand).
double
is represented in 64 bits, with 1 sign bit, 11 bits of exponent, and 52 bits of significand.
By default, Java uses double
to represent its floating-point numerals (so a literal 3.14
is typed double
). It's also the data type that will give you a much larger number range, so I would strongly encourage its use over float
.
There may be certain libraries that actually force your usage of float
, but in general - unless you can guarantee that your result will be small enough to fit in float
's prescribed range, then it's best to opt with double
.
If you require accuracy - for instance, you can't have a decimal value that is inaccurate (like 1/10 + 2/10
), or you're doing anything with currency (for example, representing $10.33 in the system), then use a BigDecimal
, which can support an arbitrary amount of precision and handle situations like that elegantly.
Your curtime
variable holds the number of seconds since the epoch. If you get one before and one after, the later one minus the earlier one is the elapsed time in seconds. You can subtract time_t
values just fine.
use like this your inline css

If you can safely make (firstName, lastName) the PRIMARY KEY or at least put a UNIQUE key on them, then you could do this:
INSERT INTO logins (firstName, lastName, logins) VALUES ('Steve', 'Smith', 1)
ON DUPLICATE KEY UPDATE logins = logins + 1;
If you can't do that, then you'd have to fetch whatever that primary key is first, so I don't think you could achieve what you want in one query.
The MyJsonDictionary class worked well for me EXCEPT that the resultant output is XML encoded - so "0" becomes "0030".
I am currently stuck at .NET 3.5, as are many others, so many of the other solutions are not available to me.
"Turns the pictures" upside down and realized I could never convince Microsoft to give me the format I wanted but...
string json = XmlConvert.DecodeName(xmlencodedJson);
TADA!
The result is what you would expect to see - regular human readable and non-XML encoded.

I would say it depends on the context. strval() or the casting operator (string) could be used. However, in most cases PHP will decide what's good for you if, for example, you use it with echo or printf...
One small note: die() needs a string and won't show any int :)
read
does not export the variable (which is a good thing most of the time). Here's an alternative which can be exported in one command, can preserve or discard linefeeds, and allows mixing of quoting-styles as needed. Works for bash and zsh.
oneLine=$(printf %s \
a \
" b " \
$'\tc\t' \
'd ' \
)
multiLine=$(printf '%s\n' \
a \
" b " \
$'\tc\t' \
'd ' \
)
I admit the need for quoting makes this ugly for SQL, but it answers the (more generally expressed) question in the title.
I use it like this
export LS_COLORS=$(printf %s \
':*rc=36:*.ini=36:*.inf=36:*.cfg=36:*~=33:*.bak=33:*$=33' \
...
':bd=40;33;1:cd=40;33;1:or=1;31:mi=31:ex=00')

and .zshrc
.
Firstly you must define select2 like this:
$('#id').select2({
placeholder: "Select groups...",
allowClear: true,
width: '100%',
})
To reset select2, simply you may use the following code block:
$("#id > option").removeAttr("selected");
$("#id").trigger("change");
This XPath is specific to the code snippet you've provided. To select <child>
with id as #grand
you can write //child[@id='#grand']
.
To get age //child[@id='#grand']/@age
Hope this helps
This is the way to convert a entity to XML File and then compress it:
private void downloadFile(EntityXML xml) {
string nameDownloadXml = "File_1.xml";
string nameDownloadZip = "File_1.zip";
var serializer = new XmlSerializer(typeof(EntityXML));
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("content-disposition", "attachment;filename=" + nameDownloadZip);
using (var memoryStream = new MemoryStream())
{
using (var archive = new ZipArchive(memoryStream, ZipArchiveMode.Create, true))
{
var demoFile = archive.CreateEntry(nameDownloadXml);
using (var entryStream = demoFile.Open())
using (StreamWriter writer = new StreamWriter(entryStream, System.Text.Encoding.UTF8))
{
serializer.Serialize(writer, xml);
}
}
using (var fileStream = Response.OutputStream)
{
memoryStream.Seek(0, SeekOrigin.Begin);
memoryStream.CopyTo(fileStream);
}
}
Response.End();
}

Other answers already pointed out that the representation of floating numbers is a thorny issue, to say the least.
Since you don't give enough context in your question, I cannot know if the decimal module can be useful for your needs:
http://docs.python.org/library/decimal.html
Among other things you can explicitly specify the precision that you wish to obtain (from the docs):
>>> getcontext().prec = 6
>>> Decimal('3.0')
Decimal('3.0')
>>> Decimal('3.1415926535')
Decimal('3.1415926535')
>>> Decimal('3.1415926535') + Decimal('2.7182818285')
Decimal('5.85987')
>>> getcontext().rounding = ROUND_UP
>>> Decimal('3.1415926535') + Decimal('2.7182818285')
Decimal('5.85988')
A simple example from my prompt (python 2.6):
>>> import decimal
>>> a = decimal.Decimal('10.000000001')
>>> a
Decimal('10.000000001')
>>> print a
10.000000001
>>> b = decimal.Decimal('10.00000000000000000000000000900000002')
>>> print b
10.00000000000000000000000000900000002
>>> print str(b)
10.00000000000000000000000000900000002
>>> len(str(b/decimal.Decimal('3.0')))
29
Maybe this can help? decimal is in python stdlib since 2.4, with additions in python 2.6.
Hope this helps, Francesco
The answer above is correct. Please be sure that you have a string data in base64 in the data variable without any prefix or stuff like that just raw data.
Here's what I did on the server side (asp.net mvc core):
string path = Path.Combine(folder, fileName);
Byte[] bytes = System.IO.File.ReadAllBytes(path);
string base64 = Convert.ToBase64String(bytes);
On the client side, I did the following code:
const xhr = new XMLHttpRequest();
xhr.open("GET", url);
xhr.setRequestHeader("Content-Type", "text/plain");
xhr.onload = () => {
var bin = atob(xhr.response);
var ab = s2ab(bin); // from example above
var blob = new Blob([ab], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;' });
var link = document.createElement('a');
link.href = window.URL.createObjectURL(blob);
link.download = 'demo.xlsx';
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
};
xhr.send();
And it works perfectly for me.
If you are storing values via any programming language
Here is an example in C#
To store date you have to convert it first and then store it
insert table1 (foodate)
values (FooDate.ToString("MM/dd/yyyy"));
FooDate is datetime variable which contains your date in your format.
You can do it as simple as this, I did it in react hooks :
(myNumber == 12) ? "true" : "false"
it was equal to this long if function below :
if (myNumber == 12) {
"true"
} else {
"false"
}
Hope it helps ^_^

It depends on what runs cron on your system, but all you have to do to run a php script from cron is to do call the location of the php installation followed by the script location. An example with crontab running every hour:
# crontab -e
00 * * * * /usr/local/bin/php /home/path/script.php
On my system, I don't even have to put the path to the php installation:
00 * * * * php /home/path/script.php
On another note, you should not be using mysql extension because it is deprecated, unless you are using an older installation of php. Read here for a comparison.
That what manual says about setOnClickListener
method is:
public void setOnClickListener (View.OnClickListener l)
Added in API level 1 Register a callback to be invoked when this view is clicked. If this view is not clickable, it becomes clickable.
Parameters
l View.OnClickListener: The callback that will run
And normally you have to use it like this
public class ExampleActivity extends Activity implements OnClickListener {
protected void onCreate(Bundle savedValues) {
...
Button button = (Button)findViewById(R.id.corky);
button.setOnClickListener(this);
}
// Implement the OnClickListener callback
public void onClick(View v) {
// do something when the button is clicked
}
...
}

You can't choose a source/destination server.
If the databases are on the same server you can do this:
If the columns of the table are equal (including order!) then you can do this:
INSERT INTO [destination database].[dbo].[destination table]
SELECT *
FROM [source database].[dbo].[source table]
If you want to do this once you can backup/restore the source database. If you need to do this more often I recommend you start a SSIS project where you define source database (there you can choose any connection on any server) and create a project where you move your data there. See more information here: http://msdn.microsoft.com/en-us/library/ms169917%28v=sql.105%29.aspx
In General:
An example of an easy way to post XML data and get the response (as a string) would be the following function:
public string postXMLData(string destinationUrl, string requestXml)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
byte[] bytes;
bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
request.ContentType = "text/xml; encoding='utf-8'";
request.ContentLength = bytes.Length;
request.Method = "POST";
Stream requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
HttpWebResponse response;
response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = response.GetResponseStream();
string responseStr = new StreamReader(responseStream).ReadToEnd();
return responseStr;
}
return null;
}
In your specific situation:
Instead of:
request.ContentType = "application/x-www-form-urlencoded";
use:
request.ContentType = "text/xml; encoding='utf-8'";
Also, remove:
string postData = "XMLData=" + Sendingxml;
And replace:
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
with:
byte[] byteArray = Encoding.UTF8.GetBytes(Sendingxml.ToString());
The standard solution didn't work for me, when changing the type from TEXT to LONGTEXT.
I had to it like this:
public function up()
{
DB::statement('ALTER TABLE mytable MODIFY mycolumn LONGTEXT;');
}
public function down()
{
DB::statement('ALTER TABLE mytable MODIFY mycolumn TEXT;');
}
This could be a Doctrine issue. More information here.
Another way to do it is to use the string() method, and set the value to the text type max length:
Schema::table('mytable', function ($table) {
// Will set the type to LONGTEXT.
$table->string('mycolumn', 4294967295)->change();
});
In testing2.php use the following code to get the name:
if ( ! empty($_POST['name'])){
$name = $_POST['name']);
}
When you create the next page, use the value of $name
to prefill the form field:
Name: <input type="text" name="name" id="name" value="<?php echo $name; ?>"><br/>
However, before doing that, be sure to use regular expressions to verify that the $name only contains valid characters, such as:
$pattern = '/^[0-9A-Za-zÁ-Úá-úàÀÜü]+$/';//integers & letters
if (preg_match($pattern, $name) == 1){
//continue
} else {
//reload form with error message
}
The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-"
for a red line, or by explicitely stating the color
argument.
import matplotlib.pyplot as plt
plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line
plt.show()
See also the plot command's documentation.
In case you already have a line with a certain color, you can change that with the lines2D.set_color()
method.
line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")
import matplotlib.pyplot as plt
import pandas as pd
df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line
plt.show()
If you want to change this color later on, you can do so by
plt.gca().get_lines()[0].set_color("black")
This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them
for ax in plt.gcf().axes:
ax.get_lines()[0].set_color("black")
and if you have more lines you can loop over them as well.
I prefer jeb's accepted answer - it is the fastest known solution and the one I use in my own scripts. (Actually there are a few additional optimizations bandied about on DosTips, but I don't think they are worth it)
But it is fun to come up with new efficient algorithms. Here is a new algorithm that uses the FINDSTR /O option:
@echo off
setlocal
set "test=Hello world!"
:: Echo the length of TEST
call :strLen test
:: Store the length of TEST in LEN
call :strLen test len
echo len=%len%
exit /b
:strLen strVar [rtnVar]
setlocal disableDelayedExpansion
set len=0
if defined %~1 for /f "delims=:" %%N in (
'"(cmd /v:on /c echo(!%~1!&echo()|findstr /o ^^"'
) do set /a "len=%%N-3"
endlocal & if "%~2" neq "" (set %~2=%len%) else echo %len%
exit /b
The code subtracts 3 because the parser juggles the command and adds a space before CMD /V /C executes it. It can be prevented by using (echo(!%~1!^^^)
.
For those that want the absolute fastest performance possible, jeb's answer can be adopted for use as a batch "macro" with arguments. This is an advanced batch technique devloped over at DosTips that eliminates the inherently slow process of CALLing a :subroutine. You can get more background on the concepts behind batch macros here, but that link uses a more primitive, less desirable syntax.
Below is an optimized @strLen macro, with examples showing differences between the macro and :subroutine usage, as well as differences in performance.

Just use the sys.getsizeof function defined in the sys
module.
sys.getsizeof(object[, default])
:Return the size of an object in bytes. The object can be any type of object. All built-in objects will return correct results, but this does not have to hold true for third-party extensions as it is implementation specific.
Only the memory consumption directly attributed to the object is accounted for, not the memory consumption of objects it refers to.
The
default
argument allows to define a value which will be returned if the object type does not provide means to retrieve the size and would cause aTypeError
.
getsizeof
calls the object’s__sizeof__
method and adds an additional garbage collector overhead if the object is managed by the garbage collector.See recursive sizeof recipe for an example of using
getsizeof()
recursively to find the size of containers and all their contents.
Usage example, in python 3.0:
>>> import sys
>>> x = 2
>>> sys.getsizeof(x)
24
>>> sys.getsizeof(sys.getsizeof)
32
>>> sys.getsizeof('this')
38
>>> sys.getsizeof('this also')
48
If you are in python < 2.6 and don't have sys.getsizeof
you can use this extensive module instead. Never used it though.
For the benefit of others, I though I'd include what I did.
Since you cannot get Visual Studio (2010 in my case) to ignore the LNK4204 warnings, my approach was to give it what it wanted: the pdb files. As I was using open source libraries in my case, I have the code building the pdb files already.
BUT, the default is to name all of the PDF files the same thing: vc100.pdb in my case. As you need a .pdb for each and every .lib, this creates a problem, especially if you are using something like ImageMagik, which creates about 20 static .lib files. You cannot have 20 lib files in one directory (which your application's linker references to link in the libraries from) and have all the 20 .pdb files called the same thing.
My solution was to go and rebuild my static library files, and configure VS2010 to name the .pdb file with respect to the PROJECT. This way, each .lib gets a similarly named .pdb, and you can put all of the LIBs and PDBs in one directory for your project to use.
So for the "Debug" configuraton, I edited:
Properties->Configuration Properties -> C/C++ -> Output Files -> Program Database File Name from
$(IntDir)vc$(PlatformToolsetVersion).pdb
to be the following value:
$(OutDir)vc$(PlatformToolsetVersion)D$(ProjectName).pdb
Now rather than somewhere in the intermediate directory, the .pdb files are written to the output directory, where the .lib files are also being written, AND most importantly, they are named with a suffix of D+project name. This means each library project produduces a project .lib and a project specific .pdb.
I'm now able to copy all of my release .lib files, my debug .lib files and the debug .pdb files into one place on my development system, and the project that uses that 3rd party library in debug mode, has the pdb files it needs in debug mode.
Use prop()

for handling the change event.

Update: React 16.0 introduced portals through ReactDOM.createPortal
link
Update: next versions of React (Fiber: probably 16 or 17) will include a method to create portals: ReactDOM.unstable_createPortal()
link
Dan Abramov answer first part is fine, but involves a lot of boilerplate. As he said, you can also use portals. I'll expand a bit on that idea.
The advantage of a portal is that the popup and the button remain very close into the React tree, with very simple parent/child communication using props: you can easily handle async actions with portals, or let the parent customize the portal.
A portal permits you to render directly inside document.body
an element that is deeply nested in your React tree.
The idea is that for example you render into body the following React tree:
<div className="layout">
<div className="outside-portal">
<Portal>
<div className="inside-portal">
PortalContent
</div>
</Portal>
</div>
</div>
And you get as output:
<body>
<div class="layout">
<div class="outside-portal">
</div>
</div>
<div class="inside-portal">
PortalContent
</div>
</body>
The inside-portal
node has been translated inside <body>
, instead of its normal, deeply-nested place.
A portal is particularly helpful for displaying elements that should go on top of your existing React components: popups, dropdowns, suggestions, hotspots
No z-index problems anymore: a portal permits you to render to <body>
. If you want to display a popup or dropdown, this is a really nice idea if you don't want to have to fight against z-index problems. The portal elements get added do document.body
in mount order, which means that unless you play with z-index
, the default behavior will be to stack portals on top of each others, in mounting order. In practice, it means that you can safely open a popup from inside another popup, and be sure that the 2nd popup will be displayed on top of the first, without having to even think about z-index
.
Most simple: use local React state: if you think, for a simple delete confirmation popup, it's not worth to have the Redux boilerplate, then you can use a portal and it greatly simplifies your code. For such a use case, where the interaction is very local and is actually quite an implementation detail, do you really care about hot-reloading, time-traveling, action logging and all the benefits Redux brings you? Personally, I don't and use local state in this case. The code becomes as simple as:
class DeleteButton extends React.Component {
static propTypes = {
onDelete: PropTypes.func.isRequired,
};
state = { confirmationPopup: false };
open = () => {
this.setState({ confirmationPopup: true });
};
close = () => {
this.setState({ confirmationPopup: false });
};
render() {
return (
<div className="delete-button">
<div onClick={() => this.open()}>Delete</div>
{this.state.confirmationPopup && (
<Portal>
<DeleteConfirmationPopup
onCancel={() => this.close()}
onConfirm={() => {
this.close();
this.props.onDelete();
}}
/>
</Portal>
)}
</div>
);
}
}
Simple: you can still use Redux state: if you really want to, you can still use connect
to choose whether or not the DeleteConfirmationPopup
is shown or not. As the portal remains deeply nested in your React tree, it is very simple to customize the behavior of this portal because your parent can pass props to the portal. If you don't use portals, you usually have to render your popups at the top of your React tree for z-index
reasons, and usually have to think about things like "how do I customize the generic DeleteConfirmationPopup I built according to the use case". And usually you'll find quite hacky solutions to this problem, like dispatching an action that contains nested confirm/cancel actions, a translation bundle key, or even worse, a render function (or something else unserializable). You don't have to do that with portals, and can just pass regular props, since DeleteConfirmationPopup
is just a child of the DeleteButton
Portals are very useful to simplify your code. I couldn't do without them anymore.
Note that portal implementations can also help you with other useful features like:
react-portal or react-modal are nice for popups, modals, and overlays that should be full-screen, generally centered in the middle of the screen.
react-tether is unknown to most React developers, yet it's one of the most useful tools you can find out there. Tether permits you to create portals, but will position automatically the portal, relative to a given target. This is perfect for tooltips, dropdowns, hotspots, helpboxes... If you have ever had any problem with position absolute
/relative
and z-index
, or your dropdown going outside of your viewport, Tether will solve all that for you.
You can, for example, easily implement onboarding hotspots, that expands to a tooltip once clicked:
Real production code here. Can't be any simpler :)
<MenuHotspots.contacts>
<ContactButton/>
</MenuHotspots.contacts>
Edit: just discovered react-gateway which permits to render portals into the node of your choice (not necessarily body)
Edit: it seems react-popper can be a decent alternative to react-tether. PopperJS is a library that only computes an appropriate position for an element, without touching the DOM directly, letting the user choose where and when he wants to put the DOM node, while Tether appends directly to the body.
Edit: there's also react-slot-fill which is interesting and can help solve similar problems by allowing to render an element to a reserved element slot that you put anywhere you want in your tree
Box Selecting
Windows & Linux: Shift + Alt + 'Mouse Left Button'
macOS: Shift + option + 'Click'
Esc to exit selection.
MacOS: Shift + Alt/Option + Command + 'arrow key'
If you have done this to make sure the user can't close the window:
frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
Then you should change your pullThePlug()
method to be
public void pullThePlug() {
// this will make sure WindowListener.windowClosing() et al. will be called.
WindowEvent wev = new WindowEvent(this, WindowEvent.WINDOW_CLOSING);
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(wev);
// this will hide and dispose the frame, so that the application quits by
// itself if there is nothing else around.
setVisible(false);
dispose();
// if you have other similar frames around, you should dispose them, too.
// finally, call this to really exit.
// i/o libraries such as WiiRemoteJ need this.
// also, this is what swing does for JFrame.EXIT_ON_CLOSE
System.exit(0);
}
I found this to be the only way that plays nice with the WindowListener
and JFrame.DO_NOTHING_ON_CLOSE
.
this can be done very easily with HTML 5, see this link http://www.html5rocks.com/en/tutorials/file/dndfiles/
Let's Say If you want to go from ViewController A --> B then
Make sure your ViewControllerA is embedded in Navigation Controller
In ViewControllerA's Button click you should have code like this.
@IBAction func goToViewController(_ sender: Any) {
if let viewControllerB = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "ViewControllerB") as? ViewControllerB {
if let navigator = navigationController {
navigator.pushViewController(viewControllerB, animated: true)
}
}
}
Look at StoryboardID = ViewControllerB
If you are not able to add a property to system.net
class library.
Then, add in Global.asax file:
ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072; //TLS 1.2
ServicePointManager.SecurityProtocol = (SecurityProtocolType)768; //TLS 1.1
And you can use it in a function, at the starting line:
ServicePointManager.SecurityProtocol = (SecurityProtocolType)768 | (SecurityProtocolType)3072;
And, it's being useful for STRIPE
payment gateway, which only supports TLS 1.1, TLS 1.2.
EDIT:
After so many questions on .NET 4.5 is installed on my server or not... here is the screenshot of Registry
on my production server:
I have only .NET framework 4.0 installed.
For those of you, who doesn't like this monstrous new AClass[] { ... }
syntax, here's some sugar:
public AClass[] c(AClass... arr) { return arr; }
Use this little function as you like:
AClass[] array;
...
array = c(object1, object2);
I am a little late but I used this:
dir /B *.* > dir_file.txt
then you can make a simple FOR loop to extract the file name and use them. e.g:
for /f "tokens=* delims= " %%a in (dir_file.txt) do (
gawk -f awk_script_file.awk %%a
)
or store them into Vars (!N1!, !N2!..!Nn!) for later use. e.g:
set /a N=0
for /f "tokens=* delims= " %%a in (dir_file.txt) do (
set /a N+=1
set v[!N!]=%%a
)
function get() {_x000D_
var arrayOfRows = document.getElementById("ta").value.split("\n");_x000D_
var docfrag = document.createDocumentFragment();_x000D_
_x000D_
var p = document.getElementById("result");_x000D_
while (p.firstChild) {_x000D_
p.removeChild(p.firstChild);_x000D_
}_x000D_
_x000D_
arrayOfRows.forEach(function(row, index, array) {_x000D_
var span = document.createElement("span");_x000D_
span.textContent = row;_x000D_
docfrag.appendChild(span);_x000D_
if(index < array.length - 1) {_x000D_
docfrag.appendChild(document.createElement("br"));_x000D_
}_x000D_
});_x000D_
_x000D_
p.appendChild(docfrag);_x000D_
}
_x000D_
<textarea id="ta" rows=3></textarea><br>_x000D_
<button onclick="get()">get</button>_x000D_
<p id="result"></p>
_x000D_
You can split textarea rows into array:
var arrayOfRows = postText.value.split("\n");
Then use it to generate, maybe, more p tags...
For PHP version 4 or later versions:
<?PHP
$input = 4;
if(is_numeric($input)){ // return **TRUE** if it is numeric
echo "The input is numeric";
}else{
echo "The input is not numeric";
}
?>
you can use isNaN(). it returns true when data is not number.
var data = 'hello there';
if(isNaN(data)){
alert("it is not number");
}else {
alert("its a valid number");
}
if (dr[dc.ColumnName].GetType().ToString() == "System.DateTime")
I normally learn by example, and here's a little something:
const lives = 0;
function catCircus () {
this.lives = 1;
const lives = 2;
const cat1 = {
lives: 5,
jumps: () => {
console.log(this.lives);
}
};
cat1.jumps(); // 1
console.log(cat1); // { lives: 5, jumps: [Function: jumps] }
const cat2 = {
lives: 5,
jumps: () => {
console.log(lives);
}
};
cat2.jumps(); // 2
console.log(cat2); // { lives: 5, jumps: [Function: jumps] }
const cat3 = {
lives: 5,
jumps: () => {
const lives = 3;
console.log(lives);
}
};
cat3.jumps(); // 3
console.log(cat3); // { lives: 5, jumps: [Function: jumps] }
const cat4 = {
lives: 5,
jumps: function () {
console.log(lives);
}
};
cat4.jumps(); // 2
console.log(cat4); // { lives: 5, jumps: [Function: jumps] }
const cat5 = {
lives: 5,
jumps: function () {
var lives = 4;
console.log(lives);
}
};
cat5.jumps(); // 4
console.log(cat5); // { lives: 5, jumps: [Function: jumps] }
const cat6 = {
lives: 5,
jumps: function () {
console.log(this.lives);
}
};
cat6.jumps(); // 5
console.log(cat6); // { lives: 5, jumps: [Function: jumps] }
const cat7 = {
lives: 5,
jumps: function thrownOutOfWindow () {
console.log(this.lives);
}
};
cat7.jumps(); // 5
console.log(cat7); // { lives: 5, jumps: [Function: thrownOutOfWindow] }
}
catCircus();
What you need is look around assertion like .+? (?=abc)
.
See: Lookahead and Lookbehind Zero-Length Assertions
Be aware that [abc]
isn't the same as abc
. Inside brackets it's not a string - each character is just one of the possibilities. Outside the brackets it becomes the string.
If the time is 11:03, then the accepted answer will print 11:3.
You could zero-pad the minutes:
"Created at {:d}:{:02d}".format(tdate.hour, tdate.minute)
Or go another way and use tdate.time()
and only take the hour/minute part:
str(tdate.time())[0:5]
You could use a template like :
#include <iostream>
using std::cerr;
using std::endl;
//qt4type
typedef unsigned int quint32;
template <typename T>
void deletep(T &) {}
template <typename T>
void deletep(T* & ptr) {
delete ptr;
ptr = 0;
}
template<typename T>
class Matrix {
public:
typedef T value_type;
Matrix() : _cols(0), _rows(0), _data(new T[0]), auto_delete(true) {};
Matrix(quint32 rows, quint32 cols, bool auto_del = true);
bool exists(quint32 row, quint32 col) const;
T & operator()(quint32 row, quint32 col);
T operator()(quint32 row, quint32 col) const;
virtual ~Matrix();
int size() const { return _rows * _cols; }
int rows() const { return _rows; }
int cols() const { return _cols; }
private:
Matrix(const Matrix &);
quint32 _rows, _cols;
mutable T * _data;
const bool auto_delete;
};
template<typename T>
Matrix<T>::Matrix(quint32 rows, quint32 cols, bool auto_del) : _rows(rows), _cols(cols), auto_delete(auto_del) {
_data = new T[rows * cols];
}
template<typename T>
inline T & Matrix<T>::operator()(quint32 row, quint32 col) {
return _data[_cols * row + col];
}
template<typename T>
inline T Matrix<T>::operator()(quint32 row, quint32 col) const {
return _data[_cols * row + col];
}
template<typename T>
bool Matrix<T>::exists(quint32 row, quint32 col) const {
return (row < _rows && col < _cols);
}
template<typename T>
Matrix<T>::~Matrix() {
if(auto_delete){
for(int i = 0, c = size(); i < c; ++i){
//will do nothing if T isn't a pointer
deletep(_data[i]);
}
}
delete [] _data;
}
int main() {
Matrix< int > m(10,10);
quint32 i = 0;
for(int x = 0; x < 10; ++x) {
for(int y = 0; y < 10; ++y, ++i) {
m(x, y) = i;
}
}
for(int x = 0; x < 10; ++x) {
for(int y = 0; y < 10; ++y) {
cerr << "@(" << x << ", " << y << ") : " << m(x,y) << endl;
}
}
}
*edit, fixed a typo.
You can't: DataFrame
columns are Series
, by definition. That said, if you make the dtype
(the type of all the elements) datetime-like, then you can access the quantities you want via the .dt
accessor (docs):
>>> df["TimeReviewed"] = pd.to_datetime(df["TimeReviewed"])
>>> df["TimeReviewed"]
205 76032930 2015-01-24 00:05:27.513000
232 76032930 2015-01-24 00:06:46.703000
233 76032930 2015-01-24 00:06:56.707000
413 76032930 2015-01-24 00:14:24.957000
565 76032930 2015-01-24 00:23:07.220000
Name: TimeReviewed, dtype: datetime64[ns]
>>> df["TimeReviewed"].dt
<pandas.tseries.common.DatetimeProperties object at 0xb10da60c>
>>> df["TimeReviewed"].dt.year
205 76032930 2015
232 76032930 2015
233 76032930 2015
413 76032930 2015
565 76032930 2015
dtype: int64
>>> df["TimeReviewed"].dt.month
205 76032930 1
232 76032930 1
233 76032930 1
413 76032930 1
565 76032930 1
dtype: int64
>>> df["TimeReviewed"].dt.minute
205 76032930 5
232 76032930 6
233 76032930 6
413 76032930 14
565 76032930 23
dtype: int64
If you're stuck using an older version of pandas
, you can always access the various elements manually (again, after converting it to a datetime-dtyped Series). It'll be slower, but sometimes that isn't an issue:
>>> df["TimeReviewed"].apply(lambda x: x.year)
205 76032930 2015
232 76032930 2015
233 76032930 2015
413 76032930 2015
565 76032930 2015
Name: TimeReviewed, dtype: int64
First off:
public class ProfileCollection implements Iterable<Profile> {
Second:
return m_Profiles.get(m_ActiveProfile);
You can append the values in the query string for the next page to see and process. You can wrap them inside the link tags:
<a href="your_page.php?var1=value1&var2=value2">
You separate each of those values with the &
sign.
Or you can create this on a button click like this:
<input type="button" onclick="document.location.href = 'your_page.php?var1=value1&var2=value2';">
A lot of the answers on this page only apply to a single cell, and OP asked for all the selected cells.
If all you want is the cell contents, and you don't care about references to the actual cells that are selected, you can just do this:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim SelectedThings As String = DataGridView1.GetClipboardContent().GetText().Replace(ChrW(9), ",")
TextBox1.Text = SelectedThings
End Sub
When Button1
is clicked, this will fill TextBox1
with the comma-separated values of the selected cells.
You should run your entire script as superuser. If you want to run some command as non-superuser, use "-u" option of sudo:
#!/bin/bash
sudo -u username command1
command2
sudo -u username command3
command4
When running as root, sudo doesn't ask for a password.
If you want to use the font to draw with graphics2d or similar, this works:
InputStream stream = ClassLoader.getSystemClassLoader().getResourceAsStream("roboto-bold.ttf")
Font font = Font.createFont(Font.TRUETYPE_FONT, stream).deriveFont(48f)
You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save
(or the before_validation
) callback. Here's an example of the relevant code for a model like yours:
class Place < ActiveRecord::Base before_save do |place| place.city = place.city.downcase.titleize place.country = place.country.downcase.titleize end end
You can also check out the Ruby on Rails guide for more info.
To answer you question more directly, something like this would work:
<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>
This just means if f.object.city
exists, display the titlecase
version of it, and if it doesn't display a blank string.
You should override Equals
and GetHashCode
meaningfully, in this case to compare the ID:
public class LinqTest
{
public int id { get; set; }
public string value { get; set; }
public override bool Equals(object obj)
{
LinqTest obj2 = obj as LinqTest;
if (obj2 == null) return false;
return id == obj2.id;
}
public override int GetHashCode()
{
return id;
}
}
Now you can use Distinct
:
List<LinqTest> uniqueIDs = myList.Distinct().ToList();
I know this is an old post but couldn't you just use <div id=xyz align="right">
for right.
You can just replace right with left, center and justify.
Worked on my site:)
float RandomFloat(float min, float max)
{
float r = (float)rand() / (float)RAND_MAX;
return min + r * (max - min);
}
I think you should do
for index, row in result:
If you wanna access by name.
Based on Vamsi Tallapudis earlier answer I came up with this dynamic path:
%LOCALAPPDATA%/Android\sdk\platform-tools
It's using a Windows Environment Variables. I find this solution to be both elegant and easy and would therefor like to share it.

A TextBlock does not actually inherit from Control so it does not have properties that you would generally associate with a Control. Your best bet for adding a border in a style is to replace the TextBlock with a Label
See this link for more on the differences between a TextBlock and other Controls
take a look at the jquery selectedbox plugin
selectOptions(value[, clear]):
Select options by value, using a string as the parameter $("#myselect2").selectOptions("Value 1");
, or a regular expression $("#myselect2").selectOptions(/^val/i);
.
You can also clear already selected options: $("#myselect2").selectOptions("Value 2", true);
@klode's answer is right.
However, you are supposed to set another response header to make your header accessible to others.
Example:
First, you add 'page-size' in response header
response.set('page-size', 20);
Then, all you need to do is expose your header
response.set('Access-Control-Expose-Headers', 'page-size')
deleteInsurance(insuranceId: any) {
const insuranceData = {
id : insuranceId
}
var reqHeader = new HttpHeaders({
"Content-Type": "application/json",
});
const httpOptions = {
headers: reqHeader,
body: insuranceData,
};
return this.http.delete<any>(this.url + "users/insurance", httpOptions);
}
Looking for EventHandling, ActionListener?
or code?
JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
textfield.setText("");
//textfield.setText(null); //or use this
}
});

copy2(src,dst)
is often more useful than copyfile(src,dst)
because:
dst
to be a directory (instead of the complete target filename), in which case the basename of src
is used for creating the new file;Here is a short example:
import shutil
shutil.copy2('/src/dir/file.ext', '/dst/dir/newname.ext') # complete target filename given
shutil.copy2('/src/file.ext', '/dst/dir') # target filename is /dst/dir/file.ext
Changing the current directory of the script process is trivial. I think the question is actually how to change the current directory of the command window from which a python script is invoked, which is very difficult. A Bat script in Windows or a Bash script in a Bash shell can do this with an ordinary cd command because the shell itself is the interpreter. In both Windows and Linux Python is a program and no program can directly change its parent's environment. However the combination of a simple shell script with a Python script doing most of the hard stuff can achieve the desired result. For example, to make an extended cd command with traversal history for backward/forward/select revisit, I wrote a relatively complex Python script invoked by a simple bat script. The traversal list is stored in a file, with the target directory on the first line. When the python script returns, the bat script reads the first line of the file and makes it the argument to cd. The complete bat script (minus comments for brevity) is:
if _%1 == _. goto cdDone
if _%1 == _? goto help
if /i _%1 NEQ _-H goto doCd
:help
echo d.bat and dSup.py 2016.03.05. Extended chdir.
echo -C = clear traversal list.
echo -B or nothing = backward (to previous dir).
echo -F or - = forward (to next dir).
echo -R = remove current from list and return to previous.
echo -S = select from list.
echo -H, -h, ? = help.
echo . = make window title current directory.
echo Anything else = target directory.
goto done
:doCd
%~dp0dSup.py %1
for /F %%d in ( %~dp0dSupList ) do (
cd %%d
if errorlevel 1 ( %~dp0dSup.py -R )
goto cdDone
)
:cdDone
title %CD%
:done
The python script, dSup.py is:

<form id="uploadbanner" enctype="multipart/form-data" method="post" action="#">

To upload a file, it is essential to set enctype="multipart/form-data"
on your form
You need that form type and then some php to process the file :)
You should probably check out Uploadify if you want something very customisable out of the box.
For c++ use std::array<int/*type*/, 10/*size*/>
instead of c-style array. This is available with c++11 standard, and which is a good practice. See it here for standard and examples. If you want to stick to old c-style arrays for reasons, there two possible ways:
int *a = new int[5]();
Here leave the parenthesis empty, otherwise it will give compile error. This will initialize all the elements in the allocated array. Here if you don't use the parenthesis, it will still initialize the integer values with zeros because new will call the constructor, which is in this case int()
.int *a = new int[5] {0, 0, 0};
This is allowed in c++11 standard. Here you can initialize array elements with any value you want. Here make sure your initializer list(values in {}) size should not be greater than your array size. Initializer list size less than array size is fine. Remaining values in array will be initialized with 0.The answer was:
heroku restart -a app_name
# The -a is the same as --app
Easily aliased with alias hra='heroku restart --app '
Which you can make a permanent alias by adding it to your .bashrc or .bash_aliases file as described at:
https://askubuntu.com/questions/17536/how-do-i-create-a-permanent-bash-alias and
Creating permanent executable aliases
Then you can just type hra app_name
You can restart a specific remote, e.g. "staging" with:
heroku restart -a app_name -r remote_name
Alternatively if you are in the root directory of your rails application you can just type
heroku restart
to restart that app and and you can create an easy alias for that with
alias hr='heroku restart'`
You can place these aliases in your .bashrc
file or (preferred) in a .bash_aliases
file which is called from .bashrc
Basically, you have three options:
EXPOSE
nor -p
EXPOSE
EXPOSE
and -p
1) If you specify neither EXPOSE
nor -p
, the service in the container will only be accessible from inside the container itself.
2) If you EXPOSE
a port, the service in the container is not accessible from outside Docker, but from inside other Docker containers. So this is good for inter-container communication.
3) If you EXPOSE
and -p
a port, the service in the container is accessible from anywhere, even outside Docker.
The reason why both are separated is IMHO because:
The documentation explicitly states:
The
EXPOSE
instruction exposes ports for use within links.
It also points you to how to link containers, which basically is the inter-container communication I talked about.
PS: If you do -p
, but do not EXPOSE
, Docker does an implicit EXPOSE
. This is because if a port is open to the public, it is automatically also open to other Docker containers. Hence -p
includes EXPOSE
. That's why I didn't list it above as a fourth case.
I found this one from another post (can't remember which) and while not the most elegant, it's simple and as a novice Linux user has given me no trouble
for i in *old_str* ; do mv -v "$i" "${i/\old_str/new_str}" ; done
if you have spaces or other special characters use a \
for i in *old_str\ * ; do mv -v "$i" "${i/\old_str\ /new_str}" ; done
for strings in sub-directories use **
for i in *\*old_str\ * ; do mv -v "$i" "${i/\old_str\ /new_str}" ; done
I do it like this:
<div class="lazyload" style="width: 1000px; height: 600px" data-src="%s">
<img class="spinner" src="spinner.gif"/>
</div>
and load with
$(window).load(function(){
$('.lazyload').each(function() {
var lazy = $(this);
var src = lazy.attr('data-src');
$('<img>').attr('src', src).load(function(){
lazy.find('img.spinner').remove();
lazy.css('background-image', 'url("'+src+'")');
});
});
});
incoming = 'arbit'
result = '%(s)s hello world %(s)s hello world %(s)s' % {'s': incoming}

I have a similar request from a client who wants to have the header, page numbers, and html footer removed. In this case, the client is presenting an HTML page that can double as a formal certificate. The added URL, page, and, header, are irrelevant and lead to a less-than-pleasing final product. In some ways, it just looks cheap.
Media=Print has not been able to disable these browser defaults. The only workaround is to tell the user to click the "Gear" button and toggle those items on/off. Seriously, I had no idea I could do that for 20 years (and we think the typical user will have a clue to click the toggle button?).
If CSS supports Media=Print, it should support the ability to control the entire end-user print experience. I appreciate that the browsers provide the added fields, but, why not allow CSS to control the overall print experience-if that is what's desired. A 90% solution could be 100% with three more fields! A simple:
#BrowserPrintDefaults{display:none}
would suffice.
Again, it's not a matter whether or not the end-user wants to print it out or not (maybe your client is very private and doesn't want printed URLs floating around. Or maybe a executive team uses a private collaboration sites?). Glad to defend the end-user, but if somebody is seeking an answer, don't respond saying it's the right of the end-user to show or hide. Sometimes it's the right of the client paying the bills.
Here are Windows wheel packages built by Chris Golke - Python Windows Binary packages - PyQt
In the filenames cp27
means C-python version 2.7, cp35
means python 3.5, etc.
Since Qt is a more complicated system with a compiled C++ codebase underlying the python interface it provides you, it can be more complex to build than just a pure python code package, which means it can be hard to install it from source.
Make sure you grab the correct Windows wheel file (python version, 32/64 bit), and then use pip to install it - e.g:
C:\path\where\wheel\is\> pip install PyQt4-4.11.4-cp35-none-win_amd64.whl
Should properly install if you are running an x64 build of Python 3.5.
NVARCHAR can store Unicode characters and takes 2 bytes per character.
Just another Eclipse plugin for *.properties files:
In similar case I used: white-space: nowrap;
The extensions available for each version of Postgresql vary. An easy way to check which extensions are available is, as has been already mentioned:
SELECT * FROM pg_available_extensions;
If the extension that you are looking for is available, you can install it using:
CREATE EXTENSION 'extensionName';
or if you want to drop it use:
DROP EXTENSION 'extensionName';
With psql
you can additionally check if the extension has been successfully installed using \dx
, and find more details about the extension using \dx+ extensioName
. It returns additional information about the extension, like which packages are used with it.
If the extension is not available in your Postgres version, then you need to download the necessary binary files and libraries and locate it them at /usr/share/conrib
In order to match a digit, you can use [0-9]
.
So you could use 5[0-9][0-9][0-9][0-9][0-9][0-9]
and [0-9][0-9][0-9][0-9]7[0-9][0-9][0-9]
. I do this a lot for zip codes.
Sorry for posting to such an old thread -- but as someone who also shares a passion for pythonic 'best', I thought I'd share our solution.
The solution is to build SQL statements using python's String Literal Concatenation (http://docs.python.org/), which could be qualified a somewhere between Option 2 and Option 4
Code Sample:
sql = ("SELECT field1, field2, field3, field4 "
"FROM table "
"WHERE condition1=1 "
"AND condition2=2;")
Works as well with f-strings:
fields = "field1, field2, field3, field4"
table = "table"
conditions = "condition1=1 AND condition2=2"
sql = (f"SELECT {fields} "
f"FROM {table} "
f"WHERE {conditions};")
There are couple ways in oracle,
create table name
(first_name varchar2(30));
insert into name values ('Peter');
insert into name values ('Paul');
insert into name values ('Mary');
Solution is 1:
select substr(max(sys_connect_by_path (first_name, ',')),2) from (select rownum r, first_name from name ) n start with r=1 connect by prior r+1=r
o/p=> Peter,Paul,Mary
Soution is 2:
select rtrim(xmlagg (xmlelement (e, first_name || ',')).extract ('//text()'), ',') first_name from name
o/p=> Peter,Paul,Mary
Use ifelse
:
frame$twohouses <- ifelse(frame$data>=2, 2, 1)
frame
data twohouses
1 0 1
2 1 1
3 2 2
4 3 2
5 4 2
...
16 0 1
17 2 2
18 1 1
19 2 2
20 0 1
21 4 2
The difference between if
and ifelse
:
if
is a control flow statement, taking a single logical value as an argumentifelse
is a vectorised function, taking vectors as all its arguments.The help page for if
, accessible via ?"if"
will also point you to ?ifelse
this
refers to a reference of the current class.
super
refers to the parent of the current class (which called the super
keyword).
By doing this
, it allows you to access methods/attributes of the current class (including its own private methods/attributes).
super
allows you to access public/protected method/attributes of parent(base) class. You cannot see the parent's private method/attributes.
Run SQL trace of long running queries and deadlocks. This shows no deadlocks at the times of the problems, and long running queries all coincide with our timeout errors, but look to be a side effect, and not the cause. Queries that are very basic that typically return instantly end up taking 30, 60 or 120 seconds to run at times. This happens for a few minutes then everything picks up and works fine after that.
It looks like some queries/transaction lock your database till they are done. You have to find out which queries are blocking and rewrite them/run them at an other time to avoid blocking other processes. At this moment the waiting queries just timeout.
An extra point to dig into is the auto increment size of your transaction log and database. Set them on a fixed size instead of a percentage of the current files. If files are getting taller the time it takes to allocate enough space will eventually longer as your transaction timeout. And your db comes to a halt.
As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server
SELECT *
FROM [FAEB].[dbo].[ExportaComisiones] AS f
JOIN [zCredifiel].[dbo].[optPerson] AS p
ON (p.vTreasuryId = f.RFC) COLLATE Database_Default
