Since jackson-databind:2.10
JsonNode has the toPrettyString()
method to easily format JSON:
objectMapper
.readTree("{}")
.toPrettyString()
;
From the docs:
public String toPrettyString()
Alternative to
toString()
that will serialize this node using Jackson default pretty-printer.Since:
2.10
JSON uses square brackets for lists ( [ "one", "two", "three" ]
) and curly brackets for key/value dictionaries (also called objects in JavaScript, {"one":1, "two":"b"}
).
The dump is quite correct, you get a list of three elements, each one is a list of two strings.
if you wanted a dictionary, maybe something like this:
x = simplejson.dumps(dict(data))
>>> {"pear": "fish", "apple": "cat", "banana": "dog"}
your expected string ('{{"apple":{"cat"},{"banana":"dog"}}
') isn't valid JSON. A
If you are in a directory or folder where the script file is available then simply change the file permission in executable mode by doing
chmod +x your_filename.sh
After that you will run the script by using the following command.
$ sudo ./your_filename.sh
Above the "." represent the current directory. Note! If you are not in the directory where the bash script file is present then you change the directory where the file is located by using
cd Directory_name/write the complete path
command. Otherwise your script can not run.
Python 3.7 works for me, I uninstalled python 3.8.1 and reinstalled 3.7.6. After that, I executed:
pip3 install --user --upgrade tensorflow
and it works
setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
int action = MotionEventCompat.getActionMasked(event);
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
longClick = false;
x1 = event.getX();
break;
case MotionEvent.ACTION_MOVE:
if (event.getEventTime() - event.getDownTime() > 500 && Math.abs(event.getX() - x1) < MIN_DISTANCE) {
longClick = true;
}
break;
case MotionEvent.ACTION_UP:
if (longClick) {
Toast.makeText(activity, "Long preess", Toast.LENGTH_SHORT).show();
}
}
return true;
}
});
If you've defined android:logo="..."
in the <application>
tag of your AndroidManifest.xml
, then you need to use this stuff to hide the icon:
<item name="logo">@android:color/transparent</item>
<item name="android:logo">@android:color/transparent</item>
The use of these two styles has properly hidden the action bar icon on a 2.3 and a 4.4 device for me (this app uses AppCompat).
I tried experimenting with the answers given. My personal finding came out to be:
git rm -r --cached .
And then
git add .
This seemed to make my working directory nice and clean. You can put your fileName in place of the dot.
With Swift 5, you can use String
's init(data:encoding:)
initializer in order to convert a Data
instance into a String
instance using UTF-8. init(data:encoding:)
has the following declaration:
init?(data: Data, encoding: String.Encoding)
Returns a
String
initialized by converting given data into Unicode characters using a given encoding.
The following Playground code shows how to use it:
import Foundation
let json = """
{
"firstName" : "John",
"lastName" : "Doe"
}
"""
let data = json.data(using: String.Encoding.utf8)!
let optionalString = String(data: data, encoding: String.Encoding.utf8)
print(String(describing: optionalString))
/*
prints:
Optional("{\n\"firstName\" : \"John\",\n\"lastName\" : \"Doe\"\n}")
*/
If you want all the bars to get the same color (fill
), you can easily add it inside geom_bar
.
ggplot(data=df, aes(x=c1+c2/2, y=c3)) +
geom_bar(stat="identity", width=c2, fill = "#FF6666")
Add fill = the_name_of_your_var
inside aes
to change the colors depending of the variable :
c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) +
geom_bar(stat="identity", width=c2)
Use scale_fill_manual()
if you want to manually the change of colors.
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) +
geom_bar(stat="identity", width=c2) +
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))
How is it not compatible with C#? Boolean.Parse and Boolean.TryParse is case insensitive and the parsing is done by comparing the value to Boolean.TrueString or Boolean.FalseString which are "True" and "False".
EDIT: When looking at the Boolean.ToString method in reflector it turns out that the strings are hard coded so the ToString method is as follows:
public override string ToString()
{
if (!this)
{
return "False";
}
return "True";
}
What is the difference between them?
Image: the generic Linux kernel binary image file.
zImage: a compressed version of the Linux kernel image that is self-extracting.
uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.
Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:
Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.
(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)
Which type of kernel image do I have to use?
You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.
ADDENDUM
I know that u-boot needs a kernel in uImage format.
That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.
Yes in Notepad++ you can do that!

And here is where you can convert mp3 or wav files into Data URI format:
An other example would be on the "created_on" column where you want to let the database handle the date creation
Yes, that is normal behavior. You basically read to the end of the file the first time (you can sort of picture it as reading a tape), so you can't read any more from it unless you reset it, by either using f.seek(0)
to reposition to the start of the file, or to close it and then open it again which will start from the beginning of the file.
If you prefer you can use the with
syntax instead which will automatically close the file for you.
e.g.,
with open('baby1990.html', 'rU') as f:
for line in f:
print line
once this block is finished executing, the file is automatically closed for you, so you could execute this block repeatedly without explicitly closing the file yourself and read the file this way over again.
I had exactly the same issue when downloading from S3 very large files.
The example solution from AWS docs just does not work:
var file = fs.createWriteStream(options.filePath);
file.on('close', function(){
if(self.logger) self.logger.info("S3Dataset file download saved to %s", options.filePath );
return callback(null,done);
});
s3.getObject({ Key: documentKey }).createReadStream().on('error', function(err) {
if(self.logger) self.logger.error("S3Dataset download error key:%s error:%@", options.fileName, error);
return callback(error);
}).pipe(file);
While this solution will work:
var file = fs.createWriteStream(options.filePath);
s3.getObject({ Bucket: this._options.s3.Bucket, Key: documentKey })
.on('error', function(err) {
if(self.logger) self.logger.error("S3Dataset download error key:%s error:%@", options.fileName, error);
return callback(error);
})
.on('httpData', function(chunk) { file.write(chunk); })
.on('httpDone', function() {
file.end();
if(self.logger) self.logger.info("S3Dataset file download saved to %s", options.filePath );
return callback(null,done);
})
.send();
The createReadStream
attempt just does not fire the end
, close
or error
callback for some reason. See here about this.
I'm using that solution also for writing down archives to gzip, since the first one (AWS example) does not work in this case either:
var gunzip = zlib.createGunzip();
var file = fs.createWriteStream( options.filePath );
s3.getObject({ Bucket: this._options.s3.Bucket, Key: documentKey })
.on('error', function (error) {
if(self.logger) self.logger.error("%@",error);
return callback(error);
})
.on('httpData', function (chunk) {
file.write(chunk);
})
.on('httpDone', function () {
file.end();
if(self.logger) self.logger.info("downloadArchive downloaded %s", options.filePath);
fs.createReadStream( options.filePath )
.on('error', (error) => {
return callback(error);
})
.on('end', () => {
if(self.logger) self.logger.info("downloadArchive unarchived %s", options.fileDest);
return callback(null, options.fileDest);
})
.pipe(gunzip)
.pipe(fs.createWriteStream(options.fileDest))
})
.send();

Try the <wbr>

In php.ini
, comment out:

error_reporting = E_ALL & ~E_NOTICE | E_STRICT
error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ER… _ERROR
error_reporting = E_ALL & ~E_NOTICE
By placing a ;
ahead of it (i.e., like ;error_reporting = E_ALL & ~E_NOTICE
)
For disabling in a single file, place error_reporting(0);
after opening a php
tag.
import re
ab = re.compile("^([A-Z]{1}[0-9]{1})+$")
ab.match(string)
I believe that should work for an uppercase, number pattern.
In Java its Webelement.getText() . Not sure about python.
This can be done in 2 ways:
if (str.match(/abc|def/)) {
...
}
if (/abc|def/.test(str)) {
....
}
In my instance the solution was moving the jQuery include just before the </head>
tag. With the Slick include at the bottom before the </body>
and just before my script include that initiates the slider.
Since 0.9.2 (including 0.10.x) node.js now validates certificates by default. This is why you could see it become more strict when you upgrade past node.js 0.8. (HT: https://github.com/mscdex/node-imap/issues/181#issuecomment-14781480)
You can avoid this with the {rejectUnauthorized:false}
option, however this has serious security implications. Anything you send to the peer will still be encrypted, but it becomes much easier to mount a man-in-the-middle attack, i.e. your data will be encrypted to the peer but the peer itself is not the server you think it is!
It would be better to first diagnose why the certificate is not authorizing and see if that could be fixed instead.
If you know the names of your computers you can use:
import socket
IP1 = socket.gethostbyname(socket.gethostname()) # local IP adress of your computer
IP2 = socket.gethostbyname('name_of_your_computer') # IP adress of remote computer
Otherwise you will have to scan for all the IP addresses that follow the same mask as your local computer (IP1), as stated in another answer.
Based on the answers before I created a string extension
extension String {
func highlightWordsIn(highlightedWords: String, attributes: [[NSAttributedStringKey: Any]]) -> NSMutableAttributedString {
let range = (self as NSString).range(of: highlightedWords)
let result = NSMutableAttributedString(string: self)
for attribute in attributes {
result.addAttributes(attribute, range: range)
}
return result
}
}
You can pass the attributes for the text to the method
Call like this
let attributes = [[NSAttributedStringKey.foregroundColor:UIColor.red], [NSAttributedStringKey.font: UIFont.boldSystemFont(ofSize: 17)]]
myLabel.attributedText = "This is a text".highlightWordsIn(highlightedWords: "is a text", attributes: attributes)
Employee emp1 = new Employee() { ID = 1, Name = "Narendra1", Salary = 11111, Experience = 3, Age = 30 };Employee emp2 = new Employee() { ID = 2, Name = "Narendra2", Salary = 21111, Experience = 10, Age = 38 };
Employee emp3 = new Employee() { ID = 3, Name = "Narendra3", Salary = 31111, Experience = 4, Age = 33 };
Employee emp4 = new Employee() { ID = 3, Name = "Narendra4", Salary = 41111, Experience = 7, Age = 33 };
List<Employee> lstEmployee = new List<Employee>();
lstEmployee.Add(emp1);
lstEmployee.Add(emp2);
lstEmployee.Add(emp3);
lstEmployee.Add(emp4);
var eemmppss=lstEmployee.Select(cc=>new {cc.ID,cc.Age}).Distinct();
This may have changed in Ruby 2.0
When I do this I get a fraction. For example on the console (either irb or rails c)
2.0.0-p195 :005 > require 'date'
=> true
2.0.0-p195 :006 > a_date = Date.parse("25/12/2013")
=> #<Date: 2013-12-25 ((2456652j,0s,0n),+0s,2299161j)>
2.0.0-p195 :007 > b_date = Date.parse("10/12/2013")
=> #<Date: 2013-12-10 ((2456637j,0s,0n),+0s,2299161j)>
2.0.0-p195 :008 > a_date-b_date
=> (15/1)
Of course, casting to an int give the expected result
2.0.0-p195 :009 > (a_date-b_date).to_i
=> 15
This also works for DateTime objects, but you have to take into consideration seconds, such as this example
2.0.0-p195 :017 > a_date_time = DateTime.now
=> #<DateTime: 2013-12-31T12:23:03-08:00 ((2456658j,73383s,725757000n),-28800s,2299161j)>
2.0.0-p195 :018 > b_date_time = DateTime.now-20
=> #<DateTime: 2013-12-11T12:23:06-08:00 ((2456638j,73386s,69998000n),-28800s,2299161j)>
2.0.0-p195 :019 > a_date_time - b_date_time
=> (1727997655759/86400000000)
2.0.0-p195 :020 > (a_date_time - b_date_time).to_i
=> 19
2.0.0-p195 :021 > c_date_time = a_date_time-20
=> #<DateTime: 2013-12-11T12:23:03-08:00 ((2456638j,73383s,725757000n),-28800s,2299161j)>
2.0.0-p195 :022 > a_date_time - c_date_time
=> (20/1)
2.0.0-p195 :023 > (a_date_time - c_date_time).to_i
=> 20
I find Func<T>
very useful when I create a component that needs to be personalized "on the fly".
Take this very simple example: a PrintListToConsole<T>
component.
A very simple object that prints this list of objects to the console. You want to let the developer that uses it personalize the output.
For example, you want to let him define a particular type of number format and so on.
Without Func
First, you have to create an interface for a class that takes the input and produces the string to print to the console.
interface PrintListConsoleRender<T> {
String Render(T input);
}
Then you have to create the class PrintListToConsole<T>
that takes the previously created interface and uses it over each element of the list.
class PrintListToConsole<T> {
private PrintListConsoleRender<T> _renderer;
public void SetRenderer(PrintListConsoleRender<T> r) {
// this is the point where I can personalize the render mechanism
_renderer = r;
}
public void PrintToConsole(List<T> list) {
foreach (var item in list) {
Console.Write(_renderer.Render(item));
}
}
}
The developer that needs to use your component has to:
implement the interface
pass the real class to the PrintListToConsole
class MyRenderer : PrintListConsoleRender<int> {
public String Render(int input) {
return "Number: " + input;
}
}
class Program {
static void Main(string[] args) {
var list = new List<int> { 1, 2, 3 };
var printer = new PrintListToConsole<int>();
printer.SetRenderer(new MyRenderer());
printer.PrintToConsole(list);
string result = Console.ReadLine();
}
}
Using Func it's much simpler
Inside the component you define a parameter of type Func<T,String>
that represents an interface of a function that takes an input parameter of type T and returns a string (the output for the console)
class PrintListToConsole<T> {
private Func<T, String> _renderFunc;
public void SetRenderFunc(Func<T, String> r) {
// this is the point where I can set the render mechanism
_renderFunc = r;
}
public void Print(List<T> list) {
foreach (var item in list) {
Console.Write(_renderFunc(item));
}
}
}
When the developer uses your component he simply passes to the component the implementation of the Func<T, String>
type, that is a function that creates the output for the console.
class Program {
static void Main(string[] args) {
var list = new List<int> { 1, 2, 3 }; // should be a list as the method signature expects
var printer = new PrintListToConsole<int>();
printer.SetRenderFunc((o) => "Number:" + o);
printer.Print(list);
string result = Console.ReadLine();
}
}
Func<T>
lets you define a generic method interface on the fly.
You define what type the input is and what type the output is.
Simple and concise.

I wrote a snippet that emulate the EventListener interface and the ie8 one, is callable even on plain objects: https://github.com/antcolag/iEventListener/blob/master/iEventListener.js

In addition to CAST and CONVERT, if you are using Sql Server 2008, you can convert to a date type (or use that type to start with), and then optionally convert again to a varchar:
declare @myDate date
set @myDate = getdate()
print cast(@myDate as varchar(10))
output:
2012-01-17
I'm not certain on what it is you're trying to achieve. But maybe you can use this:
$var =~ s/^start/foo/;
$var =~ s/end$/bar/;
I.e. just leave the middle alone and replace the start and end.
You can also disable a specific rule/rules (rather than all) by specifying them in the enable (open) and disable (close) blocks:
/* eslint-disable no-alert, no-console */
alert('foo');
console.log('bar');
/* eslint-enable no-alert */
via @goofballMagic's link above: http://eslint.org/docs/user-guide/configuring.html#configuring-rules
I think is for prevent the browser's HTML parser from interpreting the <script>, and mainly the </script> as the closing tag of the actual script, however I don't think that using document.write is a excellent idea for evaluating script blocks, why don't use the DOM...
var newScript = document.createElement("script");

The only good solution to this problem can be found in the gulp documentation:
var gulp = require('gulp');
// takes in a callback so the engine knows when it'll be done
gulp.task('one', function(cb) {
// do stuff -- async or otherwise
cb(err); // if err is not null and not undefined, the orchestration will stop, and 'two' will not run
});
// identifies a dependent task must be complete before this one begins
gulp.task('two', ['one'], function() {
// task 'one' is done now
});
gulp.task('default', ['one', 'two']);
// alternatively: gulp.task('default', ['two']);
#0000ffff
- that is the code that you need for transparent. I just did it and it worked.
you can use mongo query like this yearMonthDayhms: { $dateToString: { format: "%Y-%m-%d-%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}
HourMinute: { $dateToString: { format: "%H-%M-%S", date: {$subtract:["$cdt",14400000]}}}
Code completion. It helps a lot with exploring code.
Let's talk in from company concept. Log gives you flexible levels (see Difference between logger.info and logger.debug). Different people want to see different levels, like QAs, developers, business people. But e.printStackTrace() will print out everything. Also, like if this method will be restful called, this same error may print several times. Then the Devops or Tech-Ops people in your company may be crazy because they will receive the same error reminders.
I think a better replacement could be log.error("errors happend in XXX", e)
This will also print out whole information which is easy reading than e.printStackTrace()
The key lies in when you create the project in eclipse.
First step, you create the Java project in eclipse. Right click on the project and choose Team > Share>Git.
In the Configure Git Repository dialog, ensure that you select the option to create the Repository in the parent folder of the project.. Then you can push to github.
N.B: Eclipse will give you a warning about putting git repositories in your workspace. So when you create your project, set your project directory outside the default workspace.
For Asp.Net core you better use
<partial name="_MyPartialView" model="MyModel" />
So for example
@foreach (var item in Model)
{
<partial name="_MyItemView" model="item" />
}
If your web server is running php5, I believe you must use php5_value
. This resolved the same error I received when using php_value
.
Try looking at Double.TryParse() if you are using .NET 1.1/2.0/3.0/3.5/4.0/4.5
I have a project
A/
|--a1
|--a2
Now there is another project in our org
B/
|--b1
|--b2
|--b3
(Every module a1, b1 etc. and Parent projects A, B have their own pom.xml as per standard maven rules of parent and child)
Both projects are checked out on my local eclipse (from SVN). I am actively working on A.
I came to know that there is a good common functionality (b4) developed in B and I needed to use it.
B/
|--b1
|--b2
|--b3
|--b4 (NEW)
Developer of b4 have deployed this b4 module as an artifact in our org's repository. I included the dependancy to my module's POM i.e. a2's pom.xml. Eclipse downloaded the reuqired artifact from repo and I could import the classes in it.
Now issue starts... I needed to check the source code of b4 for some purpose and as I already had B checked out on my local eclipse I updated it from SVN and checked out module b4. I also ran pom.xml of module b4 with targets like clean, package etc. After some time when I finishedd my coding I needed to create a JAR of my module a2. I ran "package" on a2's pom.xml and BAM!! errors n errors for a2 module.. These errors were also not very user friendly. Only thing is there was b4's name for sure in logs.
Solution: After trying for many solutions for many hours, I ran "mvn -U clean install" from console in my B's project directoty (i.e. in ../codebase/B). As B is the parent, clean install command ran for all modules including b4 and it ran successfully. After this I ran "mvn -U clean install" for my parent project which is A. And this worked! a2 module got compiled, installed, (packaged later) succesfully.
Here important point was if b4 is in your workspace do not only install b4. You will need to clean-install complete B. I came up to this solution after reading answer from Zuill
EDIT: One more thing here to note that if I didn't had B project checked out in Local environment then this issue might not have occurred for me. I tend to think that this happened cause I had B checked out in my local workspace.
Ok, finally found the solution.
Probably due to lack of experience with ReactJS and web development...
var Task = React.createClass({
render: function() {
var percentage = this.props.children + '%';
....
<div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
...
I created the percentage variable outside in the render function.
Most databases have a native UUID type these days to make working with them easier. If yours doesn't, they're just 128-bit numbers, so you can use BINARY(16), and if you need the text format frequently, e.g. for troubleshooting, then add a calculated column to generate it automatically from the binary column. There is no good reason to store the (much larger) text form.
Swing + SwingX + Miglayout is my combination of choice. Miglayout is so much simpler than Swings perceived 200 different layout managers and much more powerful. Also, it provides you with the ability to "debug" your layouts, which is especially handy when creating complex layouts.
I spent a lot of time to understand all the steps. So lets describe step by step:
ssh-keygen -t rsa
. Give it an alternative like proj1.id_rsa
and hit with no doubt because you don't need a passphrase.Add new section in .ssh/config
:
Host proj1.github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/proj1.id_rsa
Take into account the first section and note that proj1.github.com
we will back to the section later.
ssh-add ~/.ssh/proj1.id_rsa
proj1.github.com
(exactly the host from the config file).
git clone [email protected]
.Don't mess up with hosts
You could use boost
:
#include <boost/date_time/gregorian/gregorian.hpp>
#include <iostream>
using namespace boost::gregorian;
int main()
{
date d = day_clock::universal_day();
std::cout << d.day() << " " << d.month() << " " << d.year();
}
The first part of your question is a duplicate of Why do I get a JsonReaderException with this code?, but the most relevant part from that (my) answer is this:
[A]
JObject
isn't the elementary base type of everything in JSON.net, butJToken
is. So even though you could say,object i = new int[0];
in C#, you can't say,
JObject i = JObject.Parse("[0, 0, 0]");
in JSON.net.
What you want is JArray.Parse
, which will accept the array you're passing it (denoted by the opening [
in your API response). This is what the "StartArray" in the error message is telling you.
As for what happened when you used JArray
, you're using arr
instead of obj
:
var rcvdData = JsonConvert.DeserializeObject<LocationData>(arr /* <-- Here */.ToString(), settings);
Swap that, and I believe it should work.
Although I'd be tempted to deserialize arr
directly as an IEnumerable<LocationData>
, which would save some code and effort of looping through the array. If you aren't going to use the parsed version separately, it's best to avoid it.
THis method allows you to have more flexibility of styling your entire content. Effectivly creating two containers that you can style. THe HTML Body tag which serves as your background, and the div with an id of container which contains your content.
This then allows you to position your content within the page, while styling a background or other effects without issue. THink of it as a "Frame" for the content.
The gem env

We can accomplish the task in two simple way one is using Json.NET dll and another is by using StringBuilder class.
Using Newtonsoft Json.NET
string JSONresult;
JSONresult = JsonConvert.SerializeObject(dt);
Response.Write(JSONresult);
Reference Link: Newtonsoft: Convert DataTable to JSON object in ASP.Net C#
Using StringBuilder
public string DataTableToJsonObj(DataTable dt)
{
DataSet ds = new DataSet();
ds.Merge(dt);
StringBuilder JsonString = new StringBuilder();
if (ds != null && ds.Tables[0].Rows.Count > 0)
{
JsonString.Append("[");
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
JsonString.Append("{");
for (int j = 0; j < ds.Tables[0].Columns.Count; j++)
{
if (j < ds.Tables[0].Columns.Count - 1)
{
JsonString.Append("\"" + ds.Tables[0].Columns[j].ColumnName.ToString() + "\":" + "\"" + ds.Tables[0].Rows[i][j].ToString() + "\",");
}
else if (j == ds.Tables[0].Columns.Count - 1)
{
JsonString.Append("\"" + ds.Tables[0].Columns[j].ColumnName.ToString() + "\":" + "\"" + ds.Tables[0].Rows[i][j].ToString() + "\"");
}
}
if (i == ds.Tables[0].Rows.Count - 1)
{
JsonString.Append("}");
}
else
{
JsonString.Append("},");
}
}
JsonString.Append("]");
return JsonString.ToString();
}
else
{
return null;
}
}
You can also do this to just get the field titles:
table = cursor.description
check = 0
for fields in table:
for name in fields:
if check < 1:
print(name),
check +=1
check =0
this work with me
File file = ..... // Save file
context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(file)));
You're better off using table-layout: fixed
Auto is the default value and with large tables can cause a bit of client side lag as the browser iterates through it to check all the sizes fit.
Fixed is far better and renders quicker to the page. The structure of the table is dependent on the tables overall width and the width of each of the columns.
Here it is applied to the original example: JSFIDDLE, You'll note that the remaining columns are crushed and overlapping their content. We can fix that with some more CSS (all I've had to do is add a class to the first TR):
table {
width: 100%;
table-layout: fixed;
}
.header-row > td {
width: 100px;
}
td.rhead {
width: 300px
}
Seen in action here: JSFIDDLE
The following code shows how to read values from an HTML form. As @pimvdb said you need to use the request.on('data'...) to capture the contents of the body.
const http = require('http')
const server = http.createServer(function(request, response) {
console.dir(request.param)
if (request.method == 'POST') {
console.log('POST')
var body = ''
request.on('data', function(data) {
body += data
console.log('Partial body: ' + body)
})
request.on('end', function() {
console.log('Body: ' + body)
response.writeHead(200, {'Content-Type': 'text/html'})
response.end('post received')
})
} else {
console.log('GET')
var html = `
<html>
<body>
<form method="post" action="http://localhost:3000">Name:
<input type="text" name="name" />
<input type="submit" value="Submit" />
</form>
</body>
</html>`
response.writeHead(200, {'Content-Type': 'text/html'})
response.end(html)
}
})
const port = 3000
const host = '127.0.0.1'
server.listen(port, host)
console.log(`Listening at http://${host}:${port}`)
If you use something like Express.js and Bodyparser then it would look like this since Express will handle the request.body concatenation
var express = require('express')
var fs = require('fs')
var app = express()
app.use(express.bodyParser())
app.get('/', function(request, response) {
console.log('GET /')
var html = `
<html>
<body>
<form method="post" action="http://localhost:3000">Name:
<input type="text" name="name" />
<input type="submit" value="Submit" />
</form>
</body>
</html>`
response.writeHead(200, {'Content-Type': 'text/html'})
response.end(html)
})
app.post('/', function(request, response) {
console.log('POST /')
console.dir(request.body)
response.writeHead(200, {'Content-Type': 'text/html'})
response.end('thanks')
})
port = 3000
app.listen(port)
console.log(`Listening at http://localhost:${port}`)
For the merge commit message, I found that I cannot amend it by using rebase
, at least on gitlab. It shows the merge as a commit but I cannot rebase onto that #sha. I found this post is helpful.
git checkout <sha of merge>
git commit --amend # edit message
git rebase HEAD previous_branch
This three lines of code did the job for changing the merge commit message (like author).
You can use pathlib
. Unfortunately this is only available in the stdlib for Python 3.4. If you have an older version you'll have to install a copy from PyPI here. This should be easy to do using pip
.
from pathlib import Path
p = Path(__file__).parents[1]
print(p)
# /absolute/path/to/two/levels/up
This uses the parents
sequence which provides access to the parent directories and chooses the 2nd one up.
Note that p
in this case will be some form of Path
object, with their own methods. If you need the paths as string then you can call str
on them.
Delete
operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirementsInsert

Use the Take method:
var foo = (from t in MyTable
select t.Foo).Take(10);
In VB LINQ has a take expression:
Dim foo = From t in MyTable _
Take 10 _
Select t.Foo
From the documentation:
Take<TSource>
enumeratessource
and yields elements untilcount
elements have been yielded orsource
contains no more elements. Ifcount
exceeds the number of elements insource
, all elements ofsource
are returned.
All of the above work, but also have to work around a problem (escapes and special characters) that doesn't need to occur in the first place: Special characters when the variable is expanded by the shell. Just don't do that (variable expansion) in the first place. Use the variable directly, without expansion.
Also, if your variable contains a secret and you want to copy that secret into a file, you might want to not have expansion in the command line as tracing/command echo of the shell commands might reveal the secret. Means, all answers which use $var
in the command line may have a potential security risk by exposing the variable contents to tracing and logging of the shell.
Use this:
printenv var >file
That means, in case of the OP question:
printenv var >"$destfile"
Note: variable names are case sensitive.
var ids = [];
$(document).ready(function($) {
$(".color_cell").bind('click', function() {
alert('Test');
ids.push(this.id);
});
});
Yes you can use an .svg file for the icon just like you can .png or another image file format. Just set the url of the icon to the directory where the .svg file is located. For example:
var icon = {
url: 'path/to/images/car.svg',
size: new google.maps.Size(sizeX, sizeY),
origin: new google.maps.Point(0, 0),
anchor: new google.maps.Point(sizeX/2, sizeY/2)
};
var marker = new google.maps.Marker({
position: event.latLng,
map: map,
draggable: false,
icon: icon
});
You may want to consider using SCLAlertView, alternative for UIAlertView or UIAlertController.
UIAlertController only works on iOS 8.x or above, SCLAlertView is a good option to support older version.
github to see the details
example:
let alertView = SCLAlertView()
alertView.addButton("First Button", target:self, selector:Selector("firstButton"))
alertView.addButton("Second Button") {
print("Second button tapped")
}
alertView.showSuccess("Button View", subTitle: "This alert view has buttons")
As an alternative to JPA/Hibernate solutions : you could use a CASCADE DELETE clause in the database definition of your foregin key on your join table, such as (Oracle syntax) :
CONSTRAINT fk_to_group
FOREIGN KEY (group_id)
REFERENCES group (id)
ON DELETE CASCADE
That way the DBMS itself automatically deletes the row that points to the group when you delete the group. And it works whether the delete is made from Hibernate/JPA, JDBC, manually in the DB or any other way.
the cascade delete feature is supported by all major DBMS (Oracle, MySQL, SQL Server, PostgreSQL).
There are two ways to handle CGI scripts, SetHandler
and AddHandler
.
SetHandler cgi-script
applies to all files in a given context, no matter how they are named, even index.html
or style.css
.
AddHandler cgi-script .pl
is similar, but applies to files ending in .pl
, in a given context. You may choose another extension or several, if you like.
Additionally, the CGI module must be loaded and Options +ExecCGI
configured. To activate the module, issue
a2enmod cgi
and restart or reload Apache. Finally, the Perl CGI script must be executable. So the execute bits must be set
chmod a+x script.pl
and it should start with
#! /usr/bin/perl
as its first line.
When you use SetHandler
or AddHandler
(and Options +ExecCGI
) outside of any directive, it is applied globally to all files. But you may restrict the context to a subset by enclosing these directives inside, e.g. Directory
<Directory /path/to/some/cgi-dir>
SetHandler cgi-script
Options +ExecCGI
</Directory>
Now SetHandler
applies only to the files inside /path/to/some/cgi-dir instead of all files of the web site. Same is with AddHandler
inside a Directory
or Location
directive, of course. It then applies to the files inside /path/to/some/cgi-dir, ending in .pl
.
You should not attempt to parse HTML with regex. HTML is not a regular language, so any regex you come up with will likely fail on some esoteric edge case. Please refer to the seminal answer to this question for specifics. While mostly formatted as a joke, it makes a very good point.
The following examples are Java, but the regex will be similar -- if not identical -- for other languages.
String target = someString.replaceAll("<[^>]*>", "");
Assuming your non-html does not contain any < or > and that your input string is correctly structured.
If you know they're a specific tag -- for example you know the text contains only <td>
tags, you could do something like this:
String target = someString.replaceAll("(?i)<td[^>]*>", "");
Edit: Omega brought up a good point in a comment on another post that this would result in multiple results all being squished together if there were multiple tags.
For example, if the input string were <td>Something</td><td>Another Thing</td>
, then the above would result in SomethingAnother Thing
.
In a situation where multiple tags are expected, we could do something like:
String target = someString.replaceAll("(?i)<td[^>]*>", " ").replaceAll("\\s+", " ").trim();
This replaces the HTML with a single space, then collapses whitespace, and then trims any on the ends.
My solution:
html, body {
min-height: 100%
}
body {
padding-bottom: 88px;
}
footer {
position: absolute;
bottom: 0;
width: 100%;
height: 88px;
}
DISTINCT
: will gives you unique values.
SELECT GROUP_CONCAT(DISTINCT(categories )) AS categories FROM table
If the file is small, you can read the whole data once:
File file = new File("a.txt");
FileInputStream fis = new FileInputStream(file);
byte[] data = new byte[(int) file.length()];
fis.read(data);
fis.close();
String str = new String(data, "UTF-8");

Maybe it is too strange, but none of the above helped me, first of all, because I had properly installed the lodash (also re-installed via above suggestions).
So long story short the issue was connected with using _.has
method from lodash.
I fixed it by simply using JS in
operator.
try to call getchar()
right before main()
returns.
This usually means that there was a network error, such as a TCP timeout. I would start by placing a sniffer (wireshark) on the connection to see if you can see any problems. If there is a TCP error, you should be able to see it. Also, you can check your router logs, if this is applicable. If wireless is involved anywhere, that is another source for these kind of errors.
Assuming you are using the command line:
show databases;
e.g. USE classicmodels;
and you should be off to the races! (Obviously, you'll have to use the correctly named database in your list.
Mysql requires you to select the particular database you are working on. I presume it is a design decision they made: it avoids a lot of potential problems: e.g. it is entirely possible, for you to use the same table names across multiple databases e.g. a users
table. In order to avoid these types of issues, they probably thought: "let's make users select the database they want".
Or you could check out the freeware StampVer for Win32 exe/dll files.
It will only change the file and product versions though if they have a version resource already. It cannot add a version resource if one doesn’t exist.
The practical way is setting font-family
to a value that is the specific name of the semibold version, such as
font-family: "Myriad pro Semibold"
if that’s the name. (Personally I use my own font listing tool, which runs on Internet Explorer only to see the fonts in my system by names as usable in CSS.)
In this approach, font-weight
is not needed (and probably better not set).
Web browsers have been poor at implementing font weights by the book: they largely cannot find the specific weight version, except bold. The workaround is to include the information in the font family name, even though this is not how things are supposed to work.
Testing with Segoe UI, which often exists in different font weight versions on Windows systems, I was able to make Internet Explorer 9 select the proper version when using the logical approach (of using the font family name Segoe UI and different font-weight
values), but it failed on Firefox 9 and Chrome 16 (only normal and bold work). On all of these browsers, for example, setting font-family: Segoe UI Light
works OK.
I don't know if this is the best way, but it has worked for me.
$root = $_SERVER['DOCUMENT_ROOT'];

The CompletionService will take your Callables with the .submit() method and you can retrieve the computed futures with the .take() method.
One thing you must not forget is to terminate the ExecutorService by calling the .shutdown() method. Also you can only call this method when you have saved a reference to the executor service so make sure to keep one.
Example code - For a fixed number of work items to be worked on in parallel:
ExecutorService service = Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors());
CompletionService<YourCallableImplementor> completionService =
new ExecutorCompletionService<YourCallableImplementor>(service);
ArrayList<Future<YourCallableImplementor>> futures = new ArrayList<Future<YourCallableImplementor>>();
for (String computeMe : elementsToCompute) {
futures.add(completionService.submit(new YourCallableImplementor(computeMe)));
}
//now retrieve the futures after computation (auto wait for it)
int received = 0;
while(received < elementsToCompute.size()) {
Future<YourCallableImplementor> resultFuture = completionService.take();
YourCallableImplementor result = resultFuture.get();
received ++;
}
//important: shutdown your ExecutorService
service.shutdown();
Example code - For a dynamic number of work items to be worked on in parallel:
public void runIt(){
ExecutorService service = Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors());
CompletionService<CallableImplementor> completionService = new ExecutorCompletionService<CallableImplementor>(service);
ArrayList<Future<CallableImplementor>> futures = new ArrayList<Future<CallableImplementor>>();
//Initial workload is 8 threads
for (int i = 0; i < 9; i++) {
futures.add(completionService.submit(write.new CallableImplementor()));
}
boolean finished = false;
while (!finished) {
try {
Future<CallableImplementor> resultFuture;
resultFuture = completionService.take();
CallableImplementor result = resultFuture.get();
finished = doSomethingWith(result.getResult());
result.setResult(null);
result = null;
resultFuture = null;
//After work package has been finished create new work package and add it to futures
futures.add(completionService.submit(write.new CallableImplementor()));
} catch (InterruptedException | ExecutionException e) {
//handle interrupted and assert correct thread / work packet count
}
}
//important: shutdown your ExecutorService
service.shutdown();
}
public class CallableImplementor implements Callable{
boolean result;
@Override
public CallableImplementor call() throws Exception {
//business logic goes here
return this;
}
public boolean getResult() {
return result;
}
public void setResult(boolean result) {
this.result = result;
}
}
[a-zA-Z0-9~@#\^\$&\*\(\)-_\+=\[\]\{\}\|\\,\.\?\s]*
This would do the matching, if you only want to allow that just wrap it in ^$ or any other delimiters that you see appropriate, if you do this no specific disallow logic is needed.
If you want to have a new data frame then:
import pandas as pd
old = pd.DataFrame({'A' : [4,5], 'B' : [10,20], 'C' : [100,50], 'D' : [-30,-50]})
new= old[['A', 'C', 'D']]
Create a folder and create another 2 folders inside it like old and new. add relevant jar files to the folders. then open the first folder using IntelliJ. after that click whatever 2 files do you want to compare and right-click and click compare archives.
There's nothing you can do about it i'm afraid as you won't be able to view it in a readable format, it's pretty much intentional and it'll show the interpreted machine code, there would be no formatting or comments as you normally get in .cs/.c files.
It's pretty much a hit and miss scenario.
Someone has already asked about it on another website
Why such complications?
public static GregorianCalendar convertFromDMY(String dd_mm_yy) throws ParseException

cal.setTime(date);
return cal;
}
as amber and sinan have noted above, the javascritp '.split' method will work just fine. Just pass it the string separator(-) and the string that you intend to split('123-abc-itchy-knee') and it will do the rest.
var coolVar = '123-abc-itchy-knee';
var coolVarParts = coolVar.split('-'); // this is an array containing the items
var1=coolVarParts[0]; //this will retrieve 123
To access each item from the array just use the respective index(indices start at zero).

First this script test the strings N having chars from 3 to 5.
For multi language (arabic, Ukrainian) you Must use this
var regex = /^([a-zA-Z0-9_-\u0600-\u065f\u066a-\u06EF\u06fa-\u06ff\ufb8a\u067e\u0686\u06af\u0750-\u077f\ufb50-\ufbc1\ufbd3-\ufd3f\ufd50-\ufd8f\ufd92-\ufdc7\ufe70-\ufefc\uFDF0-\uFDFD]+){3,5}$/; regex.test('?????');
Other wise the below is for English Alphannumeric only
/^([a-zA-Z0-9_-]){3,5}$/
P.S the above dose not accept special characters
one final thing the above dose not take space as test it will fail if there is space if you want space then add after the 0-9\s
\s
And if you want to check lenght of all string add dot .
var regex = /^([a-zA-Z0-9\s@,!=%$#&_-\u0600-\u065f\u066a-\u06EF\u06fa-\u06ff\ufb8a\u067e\u0686\u06af\u0750-\u077f\ufb50-\ufbc1\ufbd3-\ufd3f\ufd50-\ufd8f\ufd92-\ufdc7\ufe70-\ufefc\uFDF0-\uFDFD]).{1,30}$/;
Your route isn't ok, it should be like this (with ':')
app.get('/documents/:format/:type', function (req, res) {
var format = req.params.format,
type = req.params.type;
});
Also you cannot interchange parameter order unfortunately.
For more information on req.params
(and req.query
) check out the api reference here.
I had a hard time trying to figure this out on Xamarin. From the suggestions above I came up with this solution.
private string getRealPathFromURI(Android.Net.Uri contentUri)
{
string filename = "";
string thepath = "";
Android.Net.Uri filePathUri;
ICursor cursor = this.ContentResolver.Query(contentUri, null, null, null, null);
if (cursor.MoveToFirst())
{
int column_index = cursor.GetColumnIndex(MediaStore.Images.Media.InterfaceConsts.Data);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
filePathUri = Android.Net.Uri.Parse(cursor.GetString(column_index));
filename = filePathUri.LastPathSegment;
thepath = filePathUri.Path;
}
return thepath;
}
The abort
function does this. For example:
abort("Message goes here")
Note: the abort
message will be written to STDERR
as opposed to puts
which will write to STDOUT
.
If you wish to get the all instances id list in python here is the code:
import boto3
ec2=boto3.client('ec2')
instance_information = ec2.describe_instances()
for reservation in instance_information['Reservations']:
for instance in reservation['Instances']:
print(instance['InstanceId'])
perl -ne 'print if ($seen{$_} .= @ARGV) =~ /10$/' file1 file2
If I understand you correctly, you talk about the page headers and footers. They are printed by the browser. They are not part of your HTML content, so you can't influence them directly.
Show your users how to disable headers and footers in the «Page setup...» dialog.
In the end, double-hashing, mathematically, provides no benefit. In practice, however, it is useful for preventing rainbow table-based attacks. In other words, it is of no more benefit than hashing with a salt, which takes far less processor time in your application or on your server.
If you are only looking to replace all occurrences of "< "
(with space) with "<"
(no space), then you can do an lapply
over the data frame, with a gsub
for replacement:
> data <- data.frame(lapply(data, function(x) {
+ gsub("< ", "<", x)
+ }))
> data
name var1 var2
1 a <2 <3
2 a <2 <3
3 a <2 <3
4 b <2 <3
5 b <2 <3
6 b <2 <3
7 c <2 <3
8 c <2 <3
9 c <2 <3
You can do a LEFT JOIN and assert the joined column is NULL.
Example:
SELECT * FROM employees a LEFT JOIN eotm_dyn b on (a.joinfield=b.joinfield) WHERE b.name IS NULL
Using an UNREFERENCED_PARAMETER(p)
could work. I know it is defined in WinNT.h for Windows systems and can easily be defined for gcc as well (if it doesn't already have it).
UNREFERENCED PARAMETER(p)
is defined as
#define UNREFERENCED_PARAMETER(P) (P)
in WinNT.h.
For the form, use:
<form name="form1" action="<?=$_SERVER['PHP_SELF'];?>" method="get">
and for getting the value, use the get method as follows:
$value = $_GET['name_to_send_using_get'];
If you are trying to improve performance, you could try creating a persisted computed column on either a hash or concatenated value of the two columns.
Once it is persisted, provided the column is deterministic and you are using "sane" database settings, it can be indexed and / or statistics can be created on it.
I believe a distinct count of the computed column would be equivalent to your query.
I'm not sure why this hasn't come up yet but why don't you use ℃
(?) or ℉
(?) for Celsius and Fahrenheit respectively!
I always liked going after it directly:
SELECT
DB_NAME( dbid ) AS DatabaseName,
CAST( ( SUM( size ) * 8 ) / ( 1024.0 * 1024.0 ) AS decimal( 10, 2 ) ) AS DbSizeGb
FROM
sys.sysaltfiles
GROUP BY
DB_NAME( dbid )
This will work, and if you need where statement you can add it as parameter.
class GenericDAOWithJPA<T, ID extends Serializable> {
.......
public List<T> findAll() {
return entityManager.createQuery("Select t from " + persistentClass.getSimpleName() + " t").getResultList();
}
}
You can achieve what you want with the mysql console with the -s (--silent) option passed in.
It's probably a good idea to also pass in the -r (--raw) option so that special characters don't get escaped. You can use this to pipe queries like you're wanting.
mysql -u username -h hostname -p -s -r -e "select concat('this',' ','works')"
EDIT: Also, if you want to remove the column name from your output, just add another -s (mysql -ss -r etc.)

Since all these tools lack a validation function their outcomes are just drawings and no better tool for creating nice drawings is a piece of paper and pen. Afterwards you can scan your diagrams and insert them into your team's wiki.
I was also strugling with this issue and the answer is way easier than those provided over here. you can just look for it using xpath and unset it it the following method:
unset($XML->xpath("NODESNAME[@id='test']")[0]->{0});
this code will look for a node named "NODESNAME" with the id attribute "test" and remove the first occurence.
remember to save the xml using $XML->saveXML(...);

I have recently discovered that minidlna doesn't update the database if the media file is a hardlink. If you want these files to show up in the database, a full rescan is necessary.
ex: If you have a file /home/movies/foo.mkv and a hardlink in /home/minidlna/video/foo.mkv, where '/home/minidlna' is your minidlna share, you will have to do a rescan till that file appears in the db (and subsequently your dlna client).
I'm still trying to find a way around this. If anyone has any input, it's most welcome.
I've been searching for a simpler solution using only loops and if statements, and this is what I came up with. The program also works with negative integers and correctly rejects any mixed inputs that may contain both integers and other characters.
#include <stdio.h>
#include <stdlib.h> // Used for atoi() function
#include <string.h> // Used for strlen() function
#define TRUE 1
#define FALSE 0
int main(void)
{
char n[10]; // Limits characters to the equivalent of the 32 bits integers limit (10 digits)
int intTest;
printf("Give me an int: ");
do
{
scanf(" %s", n);
intTest = TRUE; // Sets the default for the integer test variable to TRUE
int i = 0, l = strlen(n);
if (n[0] == '-') // Tests for the negative sign to correctly handle negative integer values
i++;
while (i < l)
{
if (n[i] < '0' || n[i] > '9') // Tests the string characters for non-integer values
{
intTest = FALSE; // Changes intTest variable from TRUE to FALSE and breaks the loop early
break;
}
i++;
}
if (intTest == TRUE)
printf("%i\n", atoi(n)); // Converts the string to an integer and prints the integer value
else
printf("Retry: "); // Prints "Retry:" if tested FALSE
}
while (intTest == FALSE); // Continues to ask the user to input a valid integer value
return 0;
}
finally
can also be exited prematurely if an Exception
is throw
n inside a nested finally
block. The compiler will warn you that the finally
block does not complete normally or give an error that you have unreachable code. The error for unreachable code will be shown only if the throw
is not behind a conditional statement or inside a loop.
try{
}finally{
try{
}finally{
//if(someCondition) --> no error because of unreachable code
throw new RunTimeException();
}
int a = 5;//unreachable code
}
I think the problem is in your JOIN
condition.
SELECT user.user_fname,
user.user_lname,
parent.user_fname,
parent.user_lname
FROM users AS user
JOIN users AS parent
ON parent.user_id = user.user_parent_id
WHERE user.user_id = $_GET[id]
Edit:
You should probably use LEFT JOIN
if there are users with no parents.
I developed a solution based on the proposal of Kresimir Nesek. I added a new annotation @EnableMockedBean in order to make the code a bit cleaner and modular.
@EnableMockedBean
@SpringBootApplication
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes=MockedBeanTest.class)
public class MockedBeanTest {
@MockedBean
private HelloWorldService helloWorldService;
@Autowired
private MiddleComponent middleComponent;
@Test
public void helloWorldIsCalledOnlyOnce() {
middleComponent.getHelloMessage();
// THEN HelloWorldService is called only once
verify(helloWorldService, times(1)).getHelloMessage();
}
}
I have written a post explaining it.
You could initialize discount to 0 as long as your code is guaranteed not to try and use it before it is initialized. That would remove one check I suppose, I can't think of anything else.
You could put a crontab file in /etc/cron.d
which would run a script that would run your command and then delete the crontab file in /etc/cron.d
. Of course, that means your script would need to run as root.
C also does a good job at not making anything ambiguous.
Sure the dot could be overloaded to mean both things, but the arrow makes sure that the programmer knows that he's operating on a pointer, just like when the compiler won't let you mix two incompatible types.

Log4j can be a bit confusing. So lets try to understand what is going on in this file: In log4j you have two basic constructs appenders and loggers.
Appenders define how and where things are appended. Will it be logged to a file, to the console, to a database, etc.? In this case you are specifying that log statements directed to fileAppender will be put in the file sample.log
using the pattern specified in the layout tags. You could just as easily create a appender for the console or the database. Where the console appender would specify things like the layout on the screen and the database appender would have connection details and table names.
Loggers respond to logging events as they bubble up. If an event catches the interest of a specific logger it will invoke its attached appenders. In the example below you have only one logger the root logger - which responds to all logging events by default. In addition to the root logger you can specify more specific loggers that respond to events from specific packages. These loggers can have their own appenders specified using the appender-ref
tags or will otherwise inherit the appenders from the root logger. Using more specific loggers allows you to fine tune the logging level on specific packages or to direct certain packages to other appenders.
So what this file is saying is:
The net out is that if you have a logger.debug("blah blah")
in your code it will get ignored. A logger.info("Blah blah");
will output to sample.log.
The snippet below could be added to the file above with the log4j tags. This logger would inherit the appenders from <root>
but would limit the all logging events from the package org.springframework
to those logged at level info
or above.
<!-- Example Package level Logger -->
<logger name="org.springframework">
<level value="info"/>
</logger>
You probably want SETLOCAL ENABLEDELAYEDEXPANSION
. See https://devblogs.microsoft.com/oldnewthing/20060823-00/?p=29993 for details.
Basically: Normal %variables%
are expanded right aftercmd.exe
reads the command. In your case the "command" is the whole
for /F "tokens=*" %%a in ('type %FileName%') do (
set z=%%a
echo %z%
echo %%a
)
loop. At that point z
has no value yet, so echo %z%
turns into echo
. Then the loop is executed and z
is set, but its value isn't used anymore.
SETLOCAL ENABLEDELAYEDEXPANSION
enables an additional syntax, !variable!
. This also expands variables but it only does so right before each (sub-)command is executed.
SETLOCAL ENABLEDELAYEDEXPANSION
for /F "tokens=*" %%a in ('type %FileName%') do (
set z=%%a
echo !z!
echo %%a
)
This gives you the current value of z
each time the echo
runs.
I suspect you're confused here because it's fundamentally confusing. To make things worse, the whole ours/theirs stuff switches roles (becomes backwards) when you are doing a rebase.
Ultimately, during a git merge
, the "ours" branch refers to the branch you're merging into:
git checkout merge-into-ours
and the "theirs" branch refers to the (single) branch you're merging:
git merge from-theirs
and here "ours" and "theirs" makes some sense, as even though "theirs" is probably yours anyway, "theirs" is not the one you were on when you ran git merge
.
While using the actual branch name might be pretty cool, it falls apart in more complex cases. For instance, instead of the above, you might do:
git checkout ours
git merge 1234567
where you're merging by raw commit-ID. Worse, you can even do this:
git checkout 7777777 # detach HEAD
git merge 1234567 # do a test merge
in which case there are no branch names involved!
I think it's little help here, but in fact, in gitrevisions
syntax, you can refer to an individual path in the index by number, during a conflicted merge
git show :1:README
git show :2:README
git show :3:README
Stage #1 is the common ancestor of the files, stage #2 is the target-branch version, and stage #3 is the version you are merging from.
The reason the "ours" and "theirs" notions get swapped around during rebase
is that rebase works by doing a series of cherry-picks, into an anonymous branch (detached HEAD mode). The target branch is the anonymous branch, and the merge-from branch is your original (pre-rebase) branch: so "--ours" means the anonymous one rebase is building while "--theirs" means "our branch being rebased".
As for the gitattributes entry: it could have an effect: "ours" really means "use stage #2" internally. But as you note, it's not actually in place at the time, so it should not have an effect here ... well, not unless you copy it into the work tree before you start.
Also, by the way, this applies to all uses of ours and theirs, but some are on a whole file level (-s ours
for a merge strategy; git checkout --ours
during a merge conflict) and some are on a piece-by-piece basis (-X ours
or -X theirs
during a -s recursive
merge). Which probably does not help with any of the confusion.
I've never come up with a better name for these, though. And: see VonC's answer to another question, where git mergetool
introduces yet more names for these, calling them "local" and "remote"!
This code works for me just fine as of mongoDB v4.2 and mongoose 5.9.9:
const Ids = ['id1','id2','id3']
const results = await Model.find({ _id: Ids})
and the Ids can be of type ObjectId
or String
That site makes use of the "fragment" part of a url: the stuff after the "#". This is not sent to the server by the browser as part of the GET request, but can be used to store page state. So yes you can change the fragment without causing a page refresh or reload. When the page loads, your javascript reads this fragment and updates the page content appropriately, fetching data from the server via ajax requests as required. To read the fragment in js:
var fragment = location.hash;
but note that this value will include the "#" character at the beginning. To set the fragment:
location.hash = "your_state_data";
Nothing worked for me except, I loggined using pgAdmin4 and on the Dashboard I disconnected all connections except pgAdmin4 and then was able to rename by right lick on the database and properties and typed new name.
For iTunes 11 and above version:
open your iTunes "Side Bar" by going to View -> Show Side Bar drag the mobileprovision and ipa files to your iTunes "Apps" under LIBRARY Then click on your device. open you device Apps from DEVICES and click install for the application and wait for iTunes to sync
atoi can do that for you
Example:
char string[] = "1234";
int sum = atoi( string );
printf("Sum = %d\n", sum ); // Outputs: Sum = 1234
Use mcrypt_encrypt()
and mcrypt_decrypt()
with corresponding parameters. Really easy and straight forward, and you use a battle-tested encryption package.
EDIT
5 years and 4 months after this answer, the mcrypt
extension is now in the process of deprecation and eventual removal from PHP.
Here's my solution when working with hex integers and not hex strings:
def convert_hex_to_ascii(h):
chars_in_reverse = []
while h != 0x0:
chars_in_reverse.append(chr(h & 0xFF))
h = h >> 8
chars_in_reverse.reverse()
return ''.join(chars_in_reverse)
print convert_hex_to_ascii(0x7061756c)
Originally my docker container was able to reach the external internet (This is a docker service/container running on an Amazon EC2).
Since my app is an API, I followed up the creation of my container (it succeeded in pulling all the packages it needed) with updating my IP Tables to route all traffic from port 80 to the port that my API (running on docker) was listening on.
Then, later when I tried rebuilding the container it failed. After much struggle, I discovered that my previous step (setting the IPTable port forwarding rule) messed up the docker's external networking capability.
Solution: Stop your IPTable service:
sudo service iptables stop
Restart The Docker Daemon:
sudo service docker restart
Then, try rebuilding your container. Hope this helps.
Follow Up
I completely overlooked that I did not need to mess with the IP Tables to forward incoming traffic to 80 to the port that the API running on docker was running on. Instead, I just aliased port 80 to the port the API in docker was running on:
docker run -d -p 80:<api_port> <image>:<tag> <command to start api>
not sure if that's what you need but try this in ruby console:
h = Hash.new
h["name"] = "test"
h["post_number"] = 20
h["active"] = true
h
obviously it will return you a hash in console. if you want to return a hash from within a method - instead of just "h" try using "return h.inspect", something similar to:
def wordcount(str)
h = Hash.new()
str.split.each do |key|
if h[key] == nil
h[key] = 1
else
h[key] = h[key] + 1
end
end
return h.inspect

By default android will set Holo to the Dark theme. There is no theme called Holo.Dark, there's only Holo.Light, that's why you are getting the resource not found error.
So just set it to:
<style name="AppTheme" parent="android:Theme.Holo" />
All that the call to urlopen()
does (according to the docs) is return a file-like object. Once you have that, you need to call its read()
method to actually pull the JSON data across the network.
Something like:
jsonurl = urlopen(url)
text = json.loads(jsonurl.read())
print text

For my case link did NOT work as follow
ln -s /usr/bin/nodejs /usr/bin/node
But you can open /usr/local/bin/lessc as root, and change the first line from node to nodejs.

You can do something like this:
T1 = (('13', '17', '18', '21', '32'),
('07', '11', '13', '14', '28'),

This is always going to be a much safer option than just blindly accepting unauthorised end points, which should in turn only be used as a last resort.
This can be as simple as adding
require('https').globalAgent.options.ca = require('ssl-root-cas/latest').create();
to your application.
The SSL Root CAs npm package (as used here) is a very useful package regarding this problem.
ECMAScript 6 introduced template strings:
Template strings are string literals allowing embedded expressions. You can use multi-line strings and string interpolation features with them.
For example:

grep -r -e string directory
-r
is for recursive; -e
is optional but its argument specifies the regex to search for. Interestingly, POSIX grep
is not required to support -r
(or -R
), but I'm practically certain that System V in practice they (almost) all do. Some versions of grep
did, sogrep
support -R
as well as (or conceivably instead of) -r
; AFAICT, it means the same thing.

Since your issue is mostly stylistic (not wanting to fill up the constructor with a bunch of declarations) it can be solved stylistically as well.
The way I view it, many class based languages have the constructor be a function named after the class name itself. Stylistically we could use that that to make an ES6 class that stylistically still makes sense but does not group the typical actions taking place in the constructor with all the property declarations we're doing. We simply use the actual JS constructor as the "declaration area", then make a class named function that we otherwise treat as the "other constructor stuff" area, calling it at the end of the true constructor.
"use strict"; class MyClass { // only declare your properties and then call this.ClassName(); from here constructor(){ this.prop1 = 'blah 1'; this.prop2 = 'blah 2'; this.prop3 = 'blah 3'; this.MyClass(); } // all sorts of other "constructor" stuff, no longer jumbled with declarations MyClass() { doWhatever(); } }
Both will be called as the new instance is constructed.
Sorta like having 2 constructors where you separate out the declarations and the other constructor actions you want to take, and stylistically makes it not too hard to understand that's what is going on too.
I find it's a nice style to use when dealing with a lot of declarations and/or a lot of actions needing to happen on instantiation and wanting to keep the two ideas distinct from each other.
NOTE: I very purposefully do not use the typical idiomatic ideas of "initializing" (like an init()
or initialize()
method) because those are often used differently. There is a sort of presumed difference between the idea of constructing and initializing. Working with constructors people know that they're called automatically as part of instantiation. Seeing an init
method many people are going to assume without a second glance that they need to be doing something along the form of var mc = MyClass(); mc.init();
, because that's how you typically initialize. I'm not trying to add an initialization process for the user of the class, I'm trying to add to the construction process of the class itself.
While some people may do a double-take for a moment, that's actually the bit of the point: it communicates to them that the intent is part of construction, even if that makes them do a bit of a double take and go "that's not how ES6 constructors work" and take a second looking at the actual constructor to go "oh, they call it at the bottom, I see", that's far better than NOT communicating that intent (or incorrectly communicating it) and probably getting a lot of people using it wrong, trying to initialize it from the outside and junk. That's very much intentional to the pattern I suggest.
For those that don't want to follow that pattern, the exact opposite can work too. Farm the declarations out to another function at the beginning. Maybe name it "properties" or "publicProperties" or something. Then put the rest of the stuff in the normal constructor.
"use strict"; class MyClass { properties() { this.prop1 = 'blah 1'; this.prop2 = 'blah 2'; this.prop3 = 'blah 3'; } constructor() { this.properties(); doWhatever(); } }
Note that this second method may look cleaner but it also has an inherent problem where properties
gets overridden as one class using this method extends another. You'd have to give more unique names to properties
to avoid that. My first method does not have this problem because its fake half of the constructor is uniquely named after the class.
You can also use a lambda expression
public string Type
{
get => _type;
set => _type = value;
}
Import namespace :
using System.Configuration;
Create ConfigurationElement Company :
public class Company : ConfigurationElement
{
[ConfigurationProperty("name", IsRequired = true)]
public string Name
{
get
{
return this["name"] as string;
}
}
[ConfigurationProperty("code", IsRequired = true)]
public string Code
{
get
{
return this["code"] as string;
}
}
}
ConfigurationElementCollection:
public class Companies
: ConfigurationElementCollection
{
public Company this[int index]
{
get
{
return base.BaseGet(index) as Company ;
}
set
{
if (base.BaseGet(index) != null)
{
base.BaseRemoveAt(index);
}
this.BaseAdd(index, value);
}
}
public new Company this[string responseString]
{
get { return (Company) BaseGet(responseString); }
set
{
if(BaseGet(responseString) != null)
{
BaseRemoveAt(BaseIndexOf(BaseGet(responseString)));
}
BaseAdd(value);
}
}
protected override System.Configuration.ConfigurationElement CreateNewElement()
{
return new Company();
}
protected override object GetElementKey(System.Configuration.ConfigurationElement element)
{
return ((Company)element).Name;
}
}
and ConfigurationSection:
public class RegisterCompaniesConfig
: ConfigurationSection
{
public static RegisterCompaniesConfig GetConfig()
{
return (RegisterCompaniesConfig)System.Configuration.ConfigurationManager.GetSection("RegisterCompanies") ?? new RegisterCompaniesConfig();
}
[System.Configuration.ConfigurationProperty("Companies")]
[ConfigurationCollection(typeof(Companies), AddItemName = "Company")]
public Companies Companies
{
get
{
object o = this["Companies"];
return o as Companies ;
}
}
}
and you must also register your new configuration section in web.config (app.config):
<configuration>
<configSections>
<section name="Companies" type="blablabla.RegisterCompaniesConfig" ..>
then you load your config with
var config = RegisterCompaniesConfig.GetConfig();
foreach(var item in config.Companies)
{
do something ..
}
My comments on Renaud Bompuis's answer messed up.
Actually, you can use late binding, and the reference to the 11.0 object library is not required.
The following code will work without any references:
Dim f As Object
Set f = Application.FileDialog(3)
f.AllowMultiSelect = True
f.Show
MsgBox "file choosen = " & f.SelectedItems.Count
Note that the above works well in the runtime also.
Here you can find info on how to upgrade to v3: http://tosbourn.com/2013/08/javascript/upgrading-from-bootstraps-typeahead-to-typeahead-js/
Here are some examples too: http://twitter.github.io/typeahead.js/examples/
You need to enclose that in <%! %> as follows:
<%!
public String getQuarter(int i){
String quarter;
switch(i){
case 1: quarter = "Winter";
break;
case 2: quarter = "Spring";
break;
case 3: quarter = "Summer I";
break;
case 4: quarter = "Summer II";
break;
case 5: quarter = "Fall";
break;
default: quarter = "ERROR";
}
return quarter;
}
%>
You can then invoke the function within scriptlets or expressions:
<%
out.print(getQuarter(4));
%>
or
<%= getQuarter(17) %>
You have set your %JAVA_HOME
to jdk 1.7, but you are trying to compile using 1.8. Install jdk 1.8 and make sure your %JAVA_HOME
points to that or drop the target release to 1.7.
invalid target release: 1.8
The target release refers to the jdk version.
This is a very simple code I use and you manipulate it to change the colour and size of the table as you see fit.
First connect to the database:
<?php
$connect=mysql_connect('localhost', 'root', 'password');
mysql_select_db("name");
//here u select the data you want to retrieve from the db
$query="select * from tablename";
$result= mysql_query($query);
//here you check to see if any data has been found and you define the width of the table
If($result){
echo "<table width ='340' align='left'>
<tr color ='#5D9951>";
$i=0;
If(mysql_num_rows($result)>0)
{
//here you fetch the data from the database and print it in the respective columns
while($i<mysql_num_fields($result))
{
echo "<th>".mysql_field_name($result, $i)."</th>";
$i++;
}
echo "</tr>";
$color=1;
while($rows=mysql_fetch_array($result, MYSQL_ASSOC))
{
If ($color==1){
echo "<tr color='#'#cccccc'>";
foreach ($rows as $data){
echo "<td align='center'>".$data. "</td>";
}
$color=2;
}
$color=1;
}
} else {
echo"no results found";
echo "</table>";
} else {
echo "error running query:".MYSQL_error();
}
?>
It's a very elementary piece of code but it helps if you are not used to using functions.

I believe the reason there's no straightforward property to access the selected row of a WPF DataGrid is because a DataGrid's selection mode can be set to either the row-level or the cell-level. Therefore, the selection-related properties and events are all written against cell-level selection - you'll always have selected cells regardless of the grid's selection mode, but you aren't guaranteed to have a selected row.
I don't know precisely what you're trying to achieve by handling the CellEditEnding event, but to get the values of all selected cells when you select a row, take a look at handling the SelectedCellsChanged event, instead. Especially note the remarks in that article:
You can handle the SelectedCellsChanged event to be notified when the collection of selected cells is changed. If the selection includes full rows, the Selector.SelectionChanged event is also raised.
You can retrieve the AddedCells and RemovedCells from the SelectedCellsChangedEventArgs in the event handler.
Hope that helps put you on the right track. :)
You can use the following solution to solve your problem:
echo date('H:i');
Here is a one-liner that can be extended with grep to filter by name.
kubectl get pods -o jsonpath="{.items[*].metadata.name}" | \

There don't seem to be any perfect libraries or ways to do this yourself, unless you have to time to send an email to the email address and wait for a response (this might not be an option though). I ended up using a suggestion from here http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/ and adjusting the code so it would work in Java.
public static boolean isValidEmailAddress(String email) {
boolean stricterFilter = true;
String stricterFilterString = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
String laxString = ".+@.+\\.[A-Za-z]{2}[A-Za-z]*";
String emailRegex = stricterFilter ? stricterFilterString : laxString;
java.util.regex.Pattern p = java.util.regex.Pattern.compile(emailRegex);
java.util.regex.Matcher m = p.matcher(email);
return m.matches();
}
From char and varchar (Transact-SQL)
varchar [ ( n | max ) ]
Variable-length, non-Unicode character data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of data entered + 2 bytes. The data entered can be 0 characters in length. The ISO synonyms for varchar are char varying or character varying.
a cheap and nasty would be:
jQuery("#myDiv").html().replace("<br>", "\n").replace("<br />", "\n")
EDIT
jQuery("#myTextArea").val(
jQuery("#myDiv").html()
.replace(/\<br\>/g, "\n")
.replace(/\<br \/\>/g, "\n")
);
Also created a jsfiddle if needed: http://jsfiddle.net/2D3xx/
I created a simplified version using Array.prototype.includes(). My technique is similar to @Kunle Babatunde.
const isVowel = (char) => ["a", "e", "i", "o", "u"].includes(char);_x000D_
_x000D_
console.log(isVowel("o"), isVowel("s"));

I spent the entire morning solving a similar problem after having landed on this stack question. I used Dan's first solution in the answer above as the jump off point.
Problem
I have a dev (this is on my local machine), staging, and production environment. My staging and production environments live on the same server.
The app is deployed to staging via acmeserver/~staging/note-taking-app
and the production version lives at acmeserver/note-taking-app
(blame IT).
All the media files such as fonts were loading perfectly fine on dev (i.e., react-scripts start
).
However, when I created and uploaded staging and production builds, while the .css
and .js
files were loading properly, fonts were not. The compiled .css
file looked to have a correct path but the browser http request was getting some very wrong pathing (shown below).
The compiled main.fc70b10f.chunk.css
file:
@font-face {
font-family: SairaStencilOne-Regular;
src: url(note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf) ("truetype");
}
The browser http request is shown below. Note how it is adding in /static/css/
when the font file just lives in /static/media/
as well as duplicating the destination folder. I ruled out the server config being the culprit.
The Referer
is partly at fault too.
GET /~staging/note-taking-app/static/css/note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf HTTP/1.1
Host: acmeserver
Origin: http://acmeserver
Referer: http://acmeserver/~staging/note-taking-app/static/css/main.fc70b10f.chunk.css
The package.json
file had the homepage
property set to ./note-taking-app
. This was causing the problem.
{
"name": "note-taking-app",
"version": "0.1.0",
"private": true,
"homepage": "./note-taking-app",
"scripts": {
"start": "env-cmd -e development react-scripts start",
"build": "react-scripts build",
"build:staging": "env-cmd -e staging npm run build",
"build:production": "env-cmd -e production npm run build",
"test": "react-scripts test",
"eject": "react-scripts eject"
}
//...
}
Solution
That was long winded — but the solution is to:
PUBLIC_URL
env variable depending on the environment homepage
property from the package.json
fileBelow is my .env-cmdrc
file. I use .env-cmdrc
over regular .env
because it keeps everything together in one file.
{
"development": {
"PUBLIC_URL": "",
"REACT_APP_API": "http://acmeserver/~staging/note-taking-app/api"
},
"staging": {
"PUBLIC_URL": "/~staging/note-taking-app",
"REACT_APP_API": "http://acmeserver/~staging/note-taking-app/api"
},
"production": {
"PUBLIC_URL": "/note-taking-app",
"REACT_APP_API": "http://acmeserver/note-taking-app/api"
}
}
Routing via react-router-dom
works fine too — simply use the PUBLIC_URL
env variable as the basename
property.
import React from "react";
import { BrowserRouter } from "react-router-dom";
const createRouter = RootComponent => (
<BrowserRouter basename={process.env.PUBLIC_URL}>
<RootComponent />
</BrowserRouter>
);
export { createRouter };
The server config is set to route all requests to the ./index.html
file.
Finally, here is what the compiled main.fc70b10f.chunk.css
file looks like after the discussed changes were implemented.
@font-face {
font-family: SairaStencilOne-Regular;
src: url(/~staging/note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf)
format("truetype");
}

PUBLIC_URL
environment variable
Create React App assumes your application is hosted at the serving web server's root or a subpath as specified in package.json (homepage). Normally, Create React App ignores the hostname. You may use this variable to force assets to be referenced verbatim to the url you provide (hostname included). This may be particularly useful when using a CDN to host your application.
var a = ['a','b','c'];
var b = ['d','e','f'];
var c = a.concat(b); //c is now an an array with: ['a','b','c','d','e','f']
console.log( c[3] ); //c[3] will be 'd'
The answer from the Abiraman was absolutely correct. However, for newbies to git, they might forget to pull the repository. Whenever you want to do a merge from branchB into branchA. First checkout and take pull from branchB (Make sure that, your branch is updated with remote branch)
git checkout branchB
git pull
Now you local branchB is updated with remote branchB Now you can checkout to branchA
git checkout branchA
Now you are in branchA, then you can merge with branchB using following command
git merge branchB
No idea how you got your results, since it would not sort by string value... You should reverse a1
and a2
in your example
Best way in any case (as per Mladen) is:
metrics = {"sitea.com" => 745, "siteb.com" => 9, "sitec.com" => 10 }
metrics.sort_by {|_key, value| value}
# ==> [["siteb.com", 9], ["sitec.com", 10], ["sitea.com", 745]]
If you need a hash as a result, you can use to_h
(in Ruby 2.0+)
metrics.sort_by {|_key, value| value}.to_h
# ==> {"siteb.com" => 9, "sitec.com" => 10, "sitea.com", 745}
I think that you should use mysqli_connect instead of mysql_connect
cURL is disabled for most hosting control panels for security reasons, but it's required for a lot of php applications. It's not unusual for a client to request it. Since the risk of enabling cURL is minimal, you are probably better off enabling it than losing a customer. It's simply a utility that helps php scripts fetch things using standard Internet URLs.
To enable cURL, you will remove curl_exec from the "disabled list" in the control panel php advanced settings. You will also find a disabled list in the various php.ini files; look in /etc/php.ini and other paths that might exist for your control panel. You will need to restart Apache to make the change take effect.
To confirm whether cURL is enabled or disabled, create a file somewhere in your system and paste the following contents.
<?php
echo '<pre>';
var_dump(curl_version());
echo '</pre>';
?>
Save the file as testcurl.php and then run it as a php script.
testcurl.php
If cURL is disabled you will see this error.
Fatal error: Call to undefined function curl_version() in testcurl.php on line 2
If cURL is enabled you will see a long list of attributes, like this.

I use the following with a private github repository:
npm install github:mygithubuser/myproject
If you don't want to have to worry about your path or updating adb manually, you can use homebrew instead.
brew cask install android-platform-tools
For slicing (conditional or non-conditional) in general I prefer what a colleague suggested recently; Use replacement with an empty string. Easier to read the code, less code (sometimes) and less risk of specifying the wrong number of characters. Ok; I do not use Python, but in other languages I do prefer this approach:
rightmost = full_path.replace('Path=', '', 1)
or - to follow up to the first comment to this post - if this should only be done if the line starts with Path
:
rightmost = re.compile('^Path=').sub('', full_path)
The main difference to some of what has been suggested above is that there is no "magic number" (5) involved, nor any need to specify both '5
' and the string 'Path=
', In other words I prefer this approach from a code maintenance point of view.
Eugene's answer uses the correct function to get the data, but for posterity I'd like to spell out exactly how to use it in React v0.14+ (according to this answer):
import ReactDOM from 'react-dom';
//...
componentDidMount() {
var rect = ReactDOM.findDOMNode(this)
.getBoundingClientRect()
}
Is working for me perfectly, and I'm using the data to scroll to the top of the new component that just mounted.
Swift 4
override func viewDidLoad() {
super.viewDidLoad()
navigationController?.navigationBar.barTintColor = UIColor.orange
navigationController?.navigationBar.tintColor = UIColor.white
navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
}
The problem is an issue of semantic meaning (as BoltClock mentions) and visual rendering.
Originally HTML used <b>
and <i>
for these purposes, entirely stylistic commands, laid down in the semantic environment of the document markup. CSS is an attempt to separate out as far as possible the stylistic elements of the medium. Thus style information such as bold and italics should go in CSS.
<strong>
and <em>
were introduced to fill the semantic need for text to be marked as more important or stressed. They have default stylistic interpretations akin to bold and italic, but they are not bound to that fate.
In my case: I forgot to activate virtualenv
I installed "pip install example" in the wrong virtualenv

Use the parseJSON
method:
var json = '["City1","City2","City3"]';
var arr = $.parseJSON(json);
Then you have an array with the city names.
You can use this code...
public class Main {
public static void main(String args[]) {
String[] names = {"First", "Second", "Third"};//You Can Add More Names
double[] amount = {20.0, 30.0, 40.0};//You Can Add More Amount
List<Customer> customers = new ArrayList<Customer>();
int i = 0;
while (i < names.length) {
customers.add(new Customer(names[i], amount[i]));
i++;
}
}
}
Absolutely Asset Catalog is you answer, it removes the need to follow naming conventions when you are adding or updating your app icons.
Below are the steps to Migrating an App Icon Set or Launch Image Set From Apple:
1- In the project navigator, select your target.
2- Select the General pane, and scroll to the App Icons section.
3- Specify an image in the App Icon table by clicking the folder icon on the right side of the image row and selecting the image file in the dialog that appears.
4-Migrate the images in the App Icon table to an asset catalog by clicking the Use Asset Catalog button, selecting an asset catalog from the popup menu, and clicking the Migrate button.
Alternatively, you can create an empty app icon set by choosing Editor > New App Icon, and add images to the set by dragging them from the Finder or by choosing Editor > Import.
CSS is called Cascading Style Sheets because the rules are inherited. Using the following selector, will select just the direct child of the parent, but its rules will be inherited by that div
's children divs
:
div.section > div { color: red }
Now, both that div
and its children will be red
. You need to cancel out whatever you set on the parent if you don't want it to inherit:
div.section > div { color: red }
div.section > div div { color: black }
Now only that single div
that is a direct child of div.section
will be red, but its children divs
will still be black.
may be necesssary, unreference system.windows.forms and reference again.
Now I see what you are doing. You cannot send output to the screen then change the headers. If you are trying to create an XML file of map marker and download them to display, they should be in separate files.
Take this
<?php
require("database.php");
function parseToXML($htmlStr)
{
$xmlStr=str_replace('<','<',$htmlStr);
$xmlStr=str_replace('>','>',$xmlStr);
$xmlStr=str_replace('"','"',$xmlStr);
$xmlStr=str_replace("'",''',$xmlStr);
$xmlStr=str_replace("&",'&',$xmlStr);
return $xmlStr;
}
// Opens a connection to a MySQL server
$connection=mysql_connect (localhost, $username, $password);
if (!$connection) {
die('Not connected : ' . mysql_error());
}
// Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
die ('Can\'t use db : ' . mysql_error());
}
// Select all the rows in the markers table
$query = "SELECT * FROM markers WHERE 1";
$result = mysql_query($query);
if (!$result) {
die('Invalid query: ' . mysql_error());
}
header("Content-type: text/xml");
// Start XML file, echo parent node
echo '<markers>';
// Iterate through the rows, printing XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
// ADD TO XML DOCUMENT NODE
echo '<marker ';
echo 'name="' . parseToXML($row['name']) . '" ';
echo 'address="' . parseToXML($row['address']) . '" ';
echo 'lat="' . $row['lat'] . '" ';
echo 'lng="' . $row['lng'] . '" ';
echo 'type="' . $row['type'] . '" ';
echo '/>';
}
// End XML file
echo '</markers>';
?>
and place it in phpsqlajax_genxml.php
so your javascript can download the XML file. You are trying to do too many things in the same file.
The above method for Visual Studio didn't seem to apply to Visual Studio 2013, but I was able to find the described checkbox using the Project Menu and selecting my project (probably the last item on the submenu) to get to the dialog with the checkbox (on the Build tab).
The idmax
of the DataFrame returns the label index of the row with the maximum value and the behavior of argmax
depends on version of pandas
(right now it returns a warning). If you want to use the positional index, you can do the following:
max_row = df['A'].values.argmax()
or
import numpy as np
max_row = np.argmax(df['A'].values)
Note that if you use np.argmax(df['A'])
behaves the same as df['A'].argmax()
.
I think, from your description, the following would suffice:
DELETE FROM guide_category
WHERE id_guide NOT IN (SELECT id_guide FROM guide)
I assume, that there are no referential integrity constraints on the tables involved, are there?
I have used this and it seems to work with outlook, not using html but you can format the text with line breaks at least when the body is added as output.

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).
On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.
You can check awesome material design components for AngularJS:
