I had a similar issue with my imported Maven project. In one module, it cannot resolve symbol on import for part of the other module (yes, part of that module can be resolved).
I changed "Maven home directory" to a newer version solved my issue.
Update: Good for 1 hour, back to broken status...
You can use date function to format it by using the code below:
echo date("g:i a", strtotime("13:30:30 UTC"));
output: 1:30 pm
Check - JS Fiddle
HTML
<div id="myDiv">
<button class="btn btn-large btn-danger" data-toggle="tooltip" data-placement="top" title="" data-original-title="Tooltip on top">Tooltip on top</button>
</div>
Javascript
$(function () {
$("[data-toggle='tooltip']").tooltip();
});
It's the same. Your international format is already correct, and is recommended for use in all cases, where possible.
Try following logic:
<script type="text/javascript">
function showHideDiv(id) {
var e = document.getElementById(id);
if(e.style.display == null || e.style.display == "none") {
e.style.display = "block";
} else {
e.style.display = "none";
}
}
</script>
Just another way...
var elmo = {
color: 'red',
annoying: true,
height: 'unknown',
meta: { one: '1', two: '2'}
}
var subset = [elmo].map(x => ({
color: x.color,
height: x.height
}))[0]
You can use this function with an array of Objects =)
I just discovered csvkit, which is a set of Unix command-line tools for CSV files. I installed it on my Mac with pip install csvkit
. The command was:
csvsql --dialect mysql --snifflimit 100000 bigdatafile.csv > maketable.sql
You can alternatively provide a DB connection string and it can load the table directly.
I was having the same problem just now.
After adding the proper folder (C:\Python33\Scripts
) to the path, I still could not get pip
to run. All it took was running
pip.exe install -package-
instead of
pip install -package-
.
If you run a loop taking items from z, how do you expect them not to be in z? IMHO it would make more sense comparing items from a different list to z.
I had a similar issue and found that pandas.get_dummies() solved the problem. Specifically, it splits out columns of categorical data into sets of boolean columns, one new column for each unique value in each input column. In your case, you would replace train_x = test[cols]
with:
train_x = pandas.get_dummies(test[cols])
This transforms the train_x Dataframe into the following form, which RandomForestClassifier can accept:
C A_Hello A_Hola B_Bueno B_Hi
0 0 1 0 0 1
1 1 0 1 1 0
I searched for multiple options to get my git reset to specific commit, but most of them aren't so satisfactory.
I generally use this to reset the git to the specific commit in source tree.
select commit to reset on sourcetree.
In dropdowns select the active branch , first Parent Only
And right click on "Reset branch to this commit" and select hard reset option (soft, mixed and hard)
and then go to terminal git push -f
You should be all set!
Solution using display: flex (with responsive behavior): http://jsfiddle.net/dkulahin/w3472kct
HTML:
<div class="content">
<img src="myimage.jpg" alt="" />
<div class="details">
<p>Lorem ipsum dolor sit amet...</p>
</div>
</div>
CSS:
.content{
display: flex;
align-items: flex-start;
justify-content: flex-start;
}
.content img {
width: 150px;
}
.details {
width: calc(100% - 150px);
}
@media only screen and (max-width: 480px) {
.content {
flex-direction: column;
}
.details {
width: 100%;
}
}
Generate the range of data first and then shuffle it like this
import random
data = range(numLow, numHigh)
random.shuffle(data)
print data
By doing this way, you will get all the numbers in the particular range but in a random order.
But you can use random.sample
to get the number of elements you need, from a range of numbers like this
print random.sample(range(numLow, numHigh), 3)
DECIMAL_DIG
from <float.h>
should give at least a reasonable approximation of that. Since that deals with decimal digits, and it's really stored in binary, you can probably store something a little larger without losing precision, but exactly how much is hard to say. I suppose you should be able to figure it out from FLT_RADIX
and DBL_MANT_DIG
, but I'm not sure I'd completely trust the result.
as explained here
With help from numpy one can calculate for example a linear fitting.
# plot the data itself
pylab.plot(x,y,'o')
# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])
For react-router
2.4.0+
NOTE: It is advisable to migrate all your code to the latest react-router
to get all the new goodies.
As recommended in the react-router documentation:
One should use the withRouter
higher order component:
We think this new HoC is nicer and easier, and will be using it in documentation and examples, but it is not a hard requirement to switch.
As an ES6 example from the documentation:
import React from 'react'
import { withRouter } from 'react-router'
const Page = React.createClass({
componentDidMount() {
this.props.router.setRouteLeaveHook(this.props.route, () => {
if (this.state.unsaved)
return 'You have unsaved information, are you sure you want to leave this page?'
})
}
render() {
return <div>Stuff</div>
}
})
export default withRouter(Page)
With Java 8
, allow you doing something more elegant like this:
int[][] foo = new int[][] {
new int[] { 1, 2, 3 },
new int[] { 1, 2, 3, 4},
};
int length = Arrays.stream(array).max(Comparator.comparingInt(ArrayUtils::getLength)).get().length
Blanket.js works perfect too.
npm install --save-dev blanket
in front of your test/tests.js
require('blanket')({
pattern: function (filename) {
return !/node_modules/.test(filename);
}
});
run mocha -R html-cov > coverage.html
Sometimes, although you add <uses-permission android:name="android.permission.INTERNET" />
in the AndroidManifest and you have a WiFi connection, this exception can be thrown. In my case, I have turned off WiFi and then turned it on again. This resolved the error. Weird solution, but sometimes it works.
for i,j in dictionary .items():
if i=='C1':
c=[]
for k in j:
j=k+10
c.append(j)
dictionary .update({i:c})
Wipe Data
and restart the virtual device again fix the issue in my case.
$(".mytext").mouseover(function() {
var width = 250;
var height = 270;
var posX = $(this).offset().left - $(document).scrollLeft() - width + $(this).outerWidth();
var posY = $(this).offset().top - $(document).scrollTop() + $(this).outerHeight();
$("#dialog").dialog({width:width, height:height ,position:[posX, posY]});
}
Positions a dialog just under an element. I used offset() function just because it calculates the position relative to upper left corner of the browser, but position() function calculates the position relative to parent div or iframe that parent of the element.
Since you already have sent some data,
System.out.println("going to demo.jsp");
you won't be able to send a redirect.
Here's a bash shell script I created to make Laravel 5 facades very quickly.
Run this in your Laravel 5 installation directory.
make_facade.sh -f <facade_name> -n '<namespace_prefix>'
Example:
make_facade.sh -f helper -n 'App\MyApp'
If you run that example, it will create the directories Facades
and Providers
under 'your_laravel_installation_dir/app/MyApp'.
./app/MyApp/Facades/Helper.php
./app/MyApp/Facades/HelperFacade.php
./app/MyApp/Providers/HelperServiceProvider.php
After it is done, it will display a message similar to the following:
===========================
Finished
===========================
Add these lines to config/app.php:
----------------------------------
Providers: App\MyApp\Providers\HelperServiceProvider,
Alias: 'Helper' => 'App\MyApp\Facades\HelperFacade',
So update the Providers and Alias list in 'config/app.php'
Run composer -o dumpautoload
The "./app/MyApp/Facades/Helper.php" will originally look like this:
<?php
namespace App\MyApp\Facades;
class Helper
{
//
}
Now just add your methods in "./app/MyApp/Facades/Helper.php".
Here is what "./app/MyApp/Facades/Helper.php" looks like after I added a Helper function.
<?php
namespace App\MyApp\Facades;
use Request;
class Helper
{
public function isActive($pattern = null, $include_class = false)
{
return ((Request::is($pattern)) ? (($include_class) ? 'class="active"' : 'active' ) : '');
}
}
This is how it would be called:
===============================
{!! Helper::isActive('help', true) !!}
This function expects a pattern and can accept an optional second boolean argument.
If the current URL matches the pattern passed to it, it will output 'active' (or 'class="active"' if you add 'true' as a second argument to the function call).
I use it to highlight the menu that is active.

Nope, you can't use CUDA for that. CUDA is limited to NVIDIA hardware. OpenCL would be the best alternative.
Khronos itself has a list of resources. As does the StreamComputing.eu website. For your AMD specific resources, you might want to have a look at AMD's APP SDK page.
Note that at this time there are several initiatives to translate/cross-compile CUDA to different languages and APIs. One such an example is HIP. Note however that this still does not mean that CUDA runs on AMD GPUs.
When passing parameters through the URL you're able to retrieve the values as GET parameters.
Use this:
$variable = $_GET['param_name'];
//Or as you have it
$ppc = $_GET['ppc'];
It is safer to check for the variable first though:
if (isset($_GET['ppc'])) {
$ppc = $_GET['ppc'];
} else {
//Handle the case where there is no parameter
}
Here's a bit of reading on GET/POST params you should look at: http://php.net/manual/en/reserved.variables.get.php

I am also not sure about this, but try this may be it works.
Using d.Keys()(i)

Just use if
and env.BRANCH_NAME
, example:
if (env.BRANCH_NAME == "deployment") {
... do some build ...
} else {
... do something else ...
}
You can also use the data-interval attribute eg. <div class="carousel" data-interval="10000">
In Firefox, SpiderMonkey and Rhino you can wrap any code into an anonymous function and call its toSource
method, which will give you a nicely formatted source of the function.
toSource
also strips comments.
E. g.:
(function () { /* Say hello. */ var x = 'Hello!'; print(x); }).toSource()
Will be converted to a string:
function () {
var x = "Hello!";
print(x);
}
P. S.: It's not an "online tool", but all questions about general beautifying techniques are closed as duplicates of this one.
There is no .length property in C. The .length property can only be applied to arrays in object oriented programming (OOP) languages. The .length property is inherited from the object class; the class all other classes & objects inherit from in an OOP language. Also, one would use .length-1 to return the number of the last index in an array; using just the .length will return the total length of the array.
I would suggest something like this:
int index;
int jdex;
for( index = 0; index < (sizeof( my_array ) / sizeof( my_array[0] )); index++){
for( jdex = 0; jdex < (sizeof( my_array ) / sizeof( my_array[0] )); jdex++){
printf( "%d", my_array[index][jdex] );
printf( "\n" );
}
}
The line (sizeof( my_array ) / sizeof( my_array[0] )) will give you the size of the array in question. The sizeof property will return the length in bytes, so one must divide the total size of the array in bytes by how many bytes make up each element, each element takes up 4 bytes because each element is of type int, respectively. The array is of total size 16 bytes and each element is of 4 bytes so 16/4 yields 4 the total number of elements in your array because indexing starts at 0 and not 1.
The key is to add your project directory to sys.path
without considering about the env variable.
For someone who use VSCode, here's a one-line solution for you if there's a base directory of your project:
[MASTER]
init-hook='base_dir="my_spider"; import sys,os,re; _re=re.search(r".+\/" + base_dir, os.getcwd()); project_dir = _re.group() if _re else os.path.join(os.getcwd(), base_dir); sys.path.append(project_dir)'
Let me explain it a little bit:
re.search(r".+\/" + base_dir, os.getcwd()).group()
: find base directory according to the editing file
os.path.join(os.getcwd(), base_dir)
: add cwd
to sys.path
to meet command line environment

Just wanted to add a little more detail to the answers given. You can also use

I think this will help : In Controller get the list items and selected value
public ActionResult Edit(int id)
{
ItemsStore item = itemStoreRepository.FindById(id);
ViewBag.CategoryId = new SelectList(categoryRepository.Query().Get(),
"Id", "Name",item.CategoryId);
// ViewBag to pass values to View and SelectList
//(get list of items,valuefield,textfield,selectedValue)
return View(item);
}
and in View
@Html.DropDownList("CategoryId",String.Empty)
in plain JavaScript in the browser:
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
if (xhr.readyState == XMLHttpRequest.DONE ) {
if(xhr.status == 200){
console.log(xhr.responseText);
} else if(xhr.status == 400) {
console.log('There was an error 400');
} else {
console.log('something else other than 200 was returned');
}
}
}
xhr.open("GET", "mock_data.json", true);
xhr.send();
Or if you want to use Browserify to bundle your modules up using node.js. You can use superagent:
var request = require('superagent');
var url = '/mock_data.json';
request
.get(url)
.end(function(err, res){
if (res.ok) {
console.log('yay got ' + JSON.stringify(res.body));
} else {
console.log('Oh no! error ' + res.text);
}
});

If your input rows are lists rather than dictionaries, then the following is a simple solution:
import pandas as pd
list_of_lists = []
list_of_lists.append([1,2,3])
list_of_lists.append([4,5,6])
pd.DataFrame(list_of_lists, columns=['A', 'B', 'C'])
# A B C
# 0 1 2 3
# 1 4 5 6
Surely this is the correct way round....
$url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
if (!strpos($url,'mysql')) {
echo 'No mysql.'; //swapped with other echo statement
} else {
echo 'Mysql exists.';
}
Otherwise its reporting the opposite way it should...
Which one of those is indexable?
This one is definitely btree-indexable:
WHERE title >= '0' AND title < ':'
Note that ':' comes after '9' in ASCII.
That message isn't actually an error - it's just a warning that the file in question isn't of the right architecture (e.g. 32-bit vs 64-bit, wrong CPU architecture). The linker will keep looking for a library of the right type.
Of course, if you're also getting an error along the lines of can't find lPI-Http
then you have a problem :-)
It's hard to suggest what the exact remedy will be without knowing the details of your build system and makefiles, but here are a couple of shots in the dark:
CFLAGS
rather than
CTAGS
- are you sure this is
correct? (What you have may be correct - this will depend on your build system!)LDFLAGS
If that doesn't help - can you post the full error output, plus the actual command (e.g. gcc foo.c -m32 -Dxxx
etc) that was being executed?
All these answers are partially wrong.
Microsoft has clarified that Community is for ANY USE as long as your revenue is under $1 Million US dollars. That is literally the only difference between Pro and Community. Corporate or free or not, irrelevant.
Even the lack of TFS support is not true. I can verify it is present and works perfectly.
EDIT: Here is an MSDN post regarding the $1M limit: MSDN (hint: it's in the VS 2017 license)
EDIT: Even over the revenue limit, open source is still free.
Instead of looking at the source code, you should read the javadoc String.format() and Formatter syntax.
You specify the format of the value after the %. For instance for decimal integer it is d
, and for String it is s
:
String aString = "world";
int aInt = 20;
String.format("Hello, %s on line %d", aString, aInt );
Output:
Hello, world on line 20
To do what you tried (use an argument index), you use: *n*$
,
String.format("Line:%2$d. Value:%1$s. Result: Hello %1$s at line %2$d", aString, aInt );
Output:
Line:20. Value:world. Result: Hello world at line 20
Another thing - remember that if you have an with an empty src

Here's a gist which does this: https://gist.github.com/dcollien/312bce1270a5f511bf4a
(an es6 version, and a .js version which can be included in a script tag)
You can use it as follows:
<input type="file" id="select">
<img id="preview">
<script>
document.getElementById('select').onchange = function(evt) {
ImageTools.resize(this.files[0], {
width: 320, // maximum width
height: 240 // maximum height
}, function(blob, didItResize) {
// didItResize will be true if it managed to resize it, otherwise false (and will return the original file as 'blob')
document.getElementById('preview').src = window.URL.createObjectURL(blob);
// you can also now upload this blob using an XHR.
});
};
</script>
It includes a bunch of support detection and polyfills to make sure it works on as many browsers as I could manage.
(it also ignores gif images - in case they're animated)
Use the group collection of the Match object, indexing it with the capturing group name, e.g.
foreach (Match m in mc){
MessageBox.Show(m.Groups["link"].Value);
}
As Shubham Jain stated, this is working to me: driver.findElement(By.id("invoice_supplier_id")).sendKeys("value"??, "new value");
You can make td's align without changing the css by adding a div with a class of "text-center" inside the cell:
<td>
<div class="text-center">
My centered text
</div>
</td>
Posting data is a matter of sending a query string (just like the way you would send it with an URL after the ?
) as the request body.
This requires Content-Type
and Content-Length
headers, so the receiving server knows how to interpret the incoming data. (*)
var querystring = require('querystring');
var http = require('http');
var data = querystring.stringify({
username: yourUsernameValue,
password: yourPasswordValue
});
var options = {
host: 'my.url',
port: 80,
path: '/login',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': Buffer.byteLength(data)
}
};
var req = http.request(options, function(res) {
res.setEncoding('utf8');
res.on('data', function (chunk) {
console.log("body: " + chunk);
});
});
req.write(data);
req.end();
(*) Sending data requires the Content-Type header to be set correctly, i.e. application/x-www-form-urlencoded
for the traditional format that a standard HTML form would use.
It's easy to send JSON (application/json
) in exactly the same manner; just JSON.stringify()
the data beforehand.
URL-encoded data supports one level of structure (i.e. key and value). JSON is useful when it comes to exchanging data that has a nested structure.
The bottom line is: The server must be able to interpret the content type in question. It could be text/plain
or anything else; there is no need to convert data if the receiving server understands it as it is.
Add a charset parameter (e.g. application/json; charset=Windows-1252
) if your data is in an unusual character set, i.e. not UTF-8. This can be necessary if you read it from a file, for example.

I had the same problem. For me, it was caused by the default settings in the local IIS server on my machine. So the easy way to fix it, was to use the built in Visual Studio development server instead :)
Newer IIS versions on x64 machines have a setting that doesn't allow 32 bit applications to run by default. To enable 32 bit applications in the local IIS, select the relevant application pool in IIS manager, click "Advanced settings", and change "Enable 32-Bit Applications" from False to True
You should use a 'composite' or 'compound' primary key that comprises of multiple fields.
This is a perfectly acceptable solution, go here for more info :)
You need to import PIL (Pillow) for this. Suppose you have an image of size 1200, 1600. We will crop image from 400, 400 to 800, 800
from PIL import Image
img = Image.open("ImageName.jpg")
area = (400, 400, 800, 800)
cropped_img = img.crop(area)
cropped_img.show()

If you want to execute multiple commands in a for loop, you can save the result of find
with mapfile
(bash >= 4) as an variable and go through the array with ${dirlist[@]}
. It also works with directories containing spaces.
The find
command is based on the answer by Boldewyn. Further information about the find
command can be found there.
IFS=""
mapfile -t dirlist < <( find . -maxdepth 1 -mindepth 1 -type d -printf '%f\n' )
for dir in ${dirlist[@]}; do
echo ">${dir}<"
# more commands can go here ...
done
The code works for me. (after adding missing except
clause / import
statements)
Did you put \
in the original code?
urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
+ stock + '/chartdata;type=quote;range=5d/csv'
If you omit it, it could be a cause of the exception:
>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary +: 'str'
BTW, string(e)
should be str(e)
.
As already mentioned, you can use the backticks or $(cat filename)
.
What was not mentioned, and I think is important to note, is that you must remember that the shell will break apart the contents of that file according to whitespace, giving each "word" it finds to your command as an argument. And while you may be able to enclose a command-line argument in quotes so that it can contain whitespace, escape sequences, etc., reading from the file will not do the same thing. For example, if your file contains:
a "b c" d
the arguments you will get are:
a
"b
c"
d
If you want to pull each line as an argument, use the while/read/do construct:
while read i ; do command_name $i ; done < filename

Assuming that you've written an equals method for Dog correctly that compares based on the id of the Dog the easiest and simplest way to return an item in the list is as follows.
if (dogList.contains(dog)) {
return dogList.get(dogList.indexOf(dog));
}
That's less performance intensive that other approaches here. You don't need a loop at all in this case. Hope this helps.
P.S You can use Apache Commons Lang to write a simple equals method for Dog as follows:
@Override
public boolean equals(Object obj) {
EqualsBuilder builder = new EqualsBuilder().append(this.getId(), obj.getId());
return builder.isEquals();
}
The simplest one:
<div id="myIframe" style="width:640px; height:480px;">
<div style="background:transparent; position:absolute; z-index:1; width:100%; height:100%; cursor:pointer;" onClick="style.pointerEvents='none'"></div>

Here is a solution through list comprehension. cols is the list of columns to get index for:

Until Android 7.1 you will get it with:
Build.SERIAL
On Android 8 (SDK 26) and above, this field will return UNKNOWN
and must be accessed with:
Build.getSerial()
which requires the dangerous permission
android.permission.READ_PHONE_STATE
.
Since Android Q using Build.getSerial()
gets a bit more complicated by requiring:
android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE
(which can only be acquired by system apps), or for the calling package to be the device or profile owner and have the READ_PHONE_STATE
permission. This means most apps won't be able to uses this feature. See the Android Q announcement from Google.
If you just require a unique identifier, it's best to avoid using hardware identifiers as Google continuously tries to make it harder to access them for privacy reasons. You could just generate a UUID.randomUUID().toString();
and save it the first time it needs to be accessed in e.g. shared preferences. Alternatively you could use ANDROID_ID
which is a 8 byte long hex string unique to the device, user and (only Android 8+) app installation. For more info on that topic, see Best practices for unique identifiers.
You can use either of these functions:
// This should work in node.js and other ES5 compliant implementations.
function isEmptyObject(obj) {
return !Object.keys(obj).length;
}
// This should work both there and elsewhere.
function isEmptyObject(obj) {
for (var key in obj) {
if (Object.prototype.hasOwnProperty.call(obj, key)) {
return false;
}
}
return true;
}
Example usage:
if (isEmptyObject(query)) {
// There are no queries.
} else {
// There is at least one query,
// or at least the query object is not empty.
}
no, you need to do something like:
$('input.sitebg').val('000000');
but you should really be using unique IDs if you can.
You can also get more specific, such as:
$('input[type=text].sitebg').val('000000');
EDIT:
do this to find your input based on the name attribute:
$('input[name=sitebg]').val('000000');
There is also Induction app (http://inductionapp.com/), which is free & open source (https://github.com/Induction/Induction).

You can use the attribute df.empty

Google thrives on scraping websites of the world...so if it was "so illegal" then even Google won't survive ..of course other answers mention ways of mitigating IP blocks by Google. One more way to explore avoiding captcha could be scraping at random times (dint try) ..Moreover, I have a feeling, that if we provide novelty or some significant processing of data then it sounds fine at least to me...if we are simply copying a website.. or hampering its business/brand in some way...then it is bad and should be avoided..on top of it all...if you are a startup then no one will fight you as there is no benefit.. but if your entire premise is on scraping even when you are funded then you should think of more sophisticated ways...alternative APIs..eventually..Also Google keeps releasing (or depricating) fields for its API so what you want to scrap now may be in roadmap of new Google API releases..
Neither of these answers would work for me, not the Preferences NLS configuration option or the ALTER statement. This was the only approach that worked in my case:

There is no portable way to read raw characters from a Java console.
Some platform-dependent workarounds have been presented above. But to be really portable, you'd have to abandon console mode and use a windowing mode, e.g. AWT or Swing.
You can also use showdialog
Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
Handles Button3.Click
dim mydialogbox as new aboutbox1
aboutbox1.showdialog()

All the above answers are correct. Just providing with your dataset to find perfect divisor:
#include <stdio.h>
int main()
{
int arr[7] = {3,5,7,8,9,17,19};
int j = 51;
int i = 0;
for (i=0 ; i < 7; i++) {
if (j % arr[i] == 0)
printf("%d is the perfect divisor of %d\n", arr[i], j);
}
return 0;
}
1.
if(!($user_id || $user_name || $user_logged)){
//do your stuff
}
2 . No. I actually did not understand why you write such a construct.
3 . Put all values into array, for example $ar["user_id"], etc.
$lastMonth = date('M Y', strtotime("-1 month"));
var_dump($lastMonth);
$lastMonth = date('M Y', mktime(0, 0, 0, date('m') - 1, 1, date('Y')));
var_dump($lastMonth);
Each call to nextLine()
moves onto the next line, so when you are actually at the last readable line and the while
check passes inspection, the next call to nextLine()
will return EOF
.
Perhaps you could do one of the following instead:
If fileReader
is of type Scanner
:
while ((line = fileReader.hasNextLine()) != null) {
String line = fileReader.nextLine();
System.out.println(line);
}
If fileReader
is of type BufferedReader
:
String line;
while ((line = fileReader.readLine()) != null) {
System.out.println(line);
}
So you're reading the current line in the while condition and saving the line in a string for later use.

if the module userdir is enabled and your site is in a userdir (~/public_html) you must check /etc/apache2/mods-enabled/php5.conf. The following part makes it work (on Ubuntu 14.10 utopic):

#
# To re-enable PHP in user directories comment the following lines

If you use MySQL 5.5.3+, use utf8mb4_unicode_ci
instead of utf8_unicode_ci
to ensure the characters typed by your users won't give you errors.
utf8mb4

might give you hundreds of encoding-related bugs like:

Since this keeps coming up in search results for making git and github work with SSH on Windows (and because I didn't need anything from the guides above), I'm adding the following, simple solution.
(Microsoft says they are working on adding SSH to Visual Studio, and GitHub for Windows still doesn't support SSH...)
1. I installed "git for Windows" (which includes ssh and a bash shell)
https://git-scm.com/download/win
2. From the included bash shell (which, for me, was installed at: C:\Program Files\Git\git-bash.exe
)
cd
to the root level of where you want your repo saved (something like: C:\code\github\
), and
Type:
eval $(ssh-agent -s) && ssh-add "C:\Users\YOURNAMEHERE\.ssh\github_rsa"
3. Type: (the SSH link from the repo)
git clone [email protected]:RepoName/Project.git
This isn't an answer, sadly. After running into the intermittent error for some time and finally being annoyed enough to try to fix it, I have yet to find a fix. I have, however, determined a recipe for reproducing my problem, which might help others.
In my case it is SOLELY a localhost problem, on my dev machine that also has the app's DB. It's a .NET 2.0 app I'm editing with VS2005. The Win7 64 bit machine also has VS2008 and .NET 3.5 installed.
Here's what will generate the error, from a variety of forms:
A minute or two delay "waiting for localhost" and then "Connection was reset" by the browser, and global.asax
's application error trap logs:
Application_Error event: Invalid length for a Base-64 char array.
Stack Trace:
at System.Convert.FromBase64String(String s)
at System.Web.UI.ObjectStateFormatter.Deserialize(String inputString)
at System.Web.UI.Util.DeserializeWithAssert(IStateFormatter formatter, String serializedState)
at System.Web.UI.HiddenFieldPageStatePersister.Load()
In this case, it is not the SIZE of the viewstate, but something to do with page and/or viewstate caching that seems to be biting me. Setting <pages>
parameters enableEventValidation="false"
, and viewStateEncryption="Never"
in the Web.config
did not change the behavior. Neither did setting the maxPageStateFieldLength
to something modest.
You're passing the array into the function by copy. Only objects are passed by reference in PHP, and an array is not an object. Here's what you do (note the &)
function foo(&$arr) { # note the &
$arr[3] = $arr[0]+$arr[1]+$arr[2];
}
$waffles = array(1,2,3);
foo($waffles);
echo $waffles[3]; # prints 6
That aside, I'm not sure why you would do that particular operation like that. Why not just return the sum instead of assigning it to a new array element?

#elif __APPLE__
#include "TargetConditionals.h"
#if TARGET_OS_IPHONE && TARGET_IPHONE_SIMULATOR
// define something for simulator
#elif TARGET_OS_IPHONE
// define something for iphone

From an answer of @NimChimpsky in similar question:
Resource resource = new ClassPathResource("storedProcedures.sql");
InputStream resourceInputStream = resource.getInputStream();
Using ClassPathResource and interface Resource. And make sure you are adding the resources directory correctly (adding /src/main/resources/
into the classpath).
Note that Resource have a method to get a java.io.File
so you can also use:
Resource resource = new ClassPathResource("storedProcedures.sql");
FileReader fr = new FileReader(resource.getFile());

I do not think that there is need to hack around the value and label properties, use hidden input fields or to suppress events. You may add your own custom property to each Autocomplete object and then read that property value later.
Here is an example.
$(#yourInputTextBox).autocomplete({
source: function(request, response) {
// Do something with request.term (what was keyed in by the user).
// It could be an AJAX call or some search from local data.
// To keep this part short, I will do some search from local data.
// Let's assume we get some results immediately, where
// results is an array containing objects with some id and name.
var results = yourSearchClass.search(request.term);
// Populate the array that will be passed to the response callback.
var autocompleteObjects = [];
for (var i = 0; i < results.length; i++) {
var object = {
// Used by jQuery Autocomplete to show
// autocomplete suggestions as well as
// the text in yourInputTextBox upon selection.
// Assign them to a value that you want the user to see.
value: results[i].name;
label: results[i].name;
// Put our own custom id here.
// If you want to, you can even put the result object.
id: results[i].id;
};
autocompleteObjects.push(object);
}
// Invoke the response callback.
response(autocompleteObjects);
},
select: function(event, ui) {
// Retrieve your id here and do something with it.
console.log(ui.item.id);
}
});
The documentation mentions you have to pass in an array of objects with label and value properties. However, you may certainly pass in objects with more than these two properties and read them later.
Here is the relevant part I am referring to.
Array: An array can be used for local data. There are two supported formats: An array of strings: [ "Choice1", "Choice2" ] An array of objects with label and value properties: [ { label: "Choice1", value: "value1" }, ... ] The label property is displayed in the suggestion menu. The value will be inserted into the input element when a user selects an item. If just one property is specified, it will be used for both, e.g., if you provide only value properties, the value will also be used as the label.
you can do this easily by using jquery using .css property... try this one: http://api.jquery.com/css/
For newer Android 1.0.2 the following is already there in your build.gradle file
implementation fileTree(include: ['*.jar'], dir: 'libs')
Add the library jar to your libs folder -> right click the library -> click add as a library -> it asks you for the project to add it for -> select your project-> click ok The following line is automatically added to build.gradle
implementation files('libs/android-query.jar')
That did it for me. nothing more was required. i have shown this for android aquery another third party library for android.
Apparently, to get version 5.1.33 of MySQL JDBC driver to work with UTC time zone, one has to specify the serverTimezone
explicitly in the connection string.
jdbc:mysql://localhost/db?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
You could write a User Defined Function that returns the min date value like this:
select cast(-53690 as datetime)
Then use that function in your scripts, and if you ever need to change it, there is only one place to do that.
Alternately, you could use this query if you prefer it for better readability:
select cast('1753-1-1' as datetime)
Example Function
create function dbo.DateTimeMinValue()
returns datetime as
begin
return (select cast(-53690 as datetime))
end
Usage
select dbo.DateTimeMinValue() as DateTimeMinValue
DateTimeMinValue

1753-01-01 00:00:00.000
When you insert ANY variable into HTML, unless you want the browser to interpret the variable itself as HTML, it's best to use htmlspecialchars()
on it. Among other things, it prevents hackers from inserting arbitrary HTML in your page.
The value of $_SERVER['PHP_SELF']
is taken directly from the URL entered in the browser. Therefore if you use it without htmlspecialchars()
, you're allowing hackers to directly manipulate the output of your code.
For example, if I e-mail you a link to http://example.com/"><script>malicious_code_here()</script><span class="
and you have <form action="<?php echo $_SERVER['PHP_SELF'] ?>">
, the output will be:
<form action="http://example.com/"><script>malicious_code_here()</script><span class="">
My script will run, and you will be none the wiser. If you were logged in, I may have stolen your cookies, or scraped confidential info from your page.
However, if you used <form action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']) ?>">
, the output would be:
<form action="http://example.com/"><script>cookie_stealing_code()</script><span class="">
When you submitted the form, you'd have a weird URL, but at least my evil script did not run.
On the other hand, if you used <form action="">
, then the output would be the same no matter what I added to my link. This is the option I would recommend.

public ActionResult ViewNextItem(int? id)
makes the id
integer a nullable type, no need for string<->int conversions.
The following cites the C11 standard (final draft).
6.3.1.2: When any scalar value is converted to _Bool, the result is 0 if the value compares equal to 0; otherwise, the result is 1.
bool
(mapped by stdbool.h
to the internal name _Bool
for C) itself is an unsigned integer type:
... The type _Bool and the unsigned integer types that correspond to the standard signed integer types are the standard unsigned integer types.
According to 6.2.5p2:
An object declared as type _Bool is large enough to store the values 0 and 1.
AFAIK these definitions are semantically identical to C++ - with the minor difference of the built-in(!) names. bool
for C++ and _Bool
for C.
Note that C does not use the term rvalues as C++ does. However, in C pointers are scalars, so assigning a pointer to a _Bool
behaves as in C++.
// String.class here is the parameter type, that might not be the case with you
Method method = clazz.getMethod("methodName", String.class);
Object o = method.invoke(null, "whatever");
In case the method is private use getDeclaredMethod()
instead of getMethod()
. And call setAccessible(true)
on the method object.
The equivalent of null
in VB is Nothing
so your check wants to be:
If editTransactionRow.pay_id IsNot Nothing Then
stTransactionPaymentID = editTransactionRow.pay_id
End If
Or possibly, if you are actually wanting to check for a SQL null value:
If editTransactionRow.pay_id <> DbNull.Value Then
...
End If
Strings are immutable, so actully you can't change the String afterwards (you can only make the variable that held the String object point to a different String object).
However, that is not the reason why you can bind any variable to a final
parameter. All the compiler checks is that the parameter is not reassigned within the method. This is good for documentation purposes, arguably good style, and may even help optimize the byte code for speed (although this seems not to do very much in practice).
But even if you do reassign a parameter within a method, the caller doesn't notice that, because java does all parameter passing by value. After the sequence
a = someObject();
process(a);
the fields of a may have changed, but a is still the same object it was before. In pass-by-reference languages this may not be true.
You can dump a query as csv like this:
SELECT * from myTable
INTO OUTFILE '/tmp/querydump.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'

Keeping in mind the points made in @John Woo's comment/link above, this is how I typically would handle it:
SELECT t1.ID, t1.Name
FROM Table1 t1
WHERE NOT EXISTS (
SELECT TOP 1 NULL
FROM Table2 t2
WHERE t1.ID = t2.ID
)
I have a span. I want to take the value of attribute data-txt-lang, which is used defined.
$(document).ready(function ()
{
<span class="txt-lang-btn" data-txt-lang="en">EN</span>
alert($('.txt-lang-btn').attr('data-txt-lang'));
});
infowindow.open(null,null);
will close opened infowindow. It will work same as
For GNU/Linux & MacOS (or generally UNIX like) systems, I've used below method which works fine:
private int tryGetPid(Process process)
{
if (process.getClass().getName().equals("java.lang.UNIXProcess"))
{
try
{
Field f = process.getClass().getDeclaredField("pid");
f.setAccessible(true);
return f.getInt(process);
}
catch (IllegalAccessException | IllegalArgumentException | NoSuchFieldException | SecurityException e)
{
}
}
return 0;
}
table {
border-collapse: collapse;
}
td {
padding-top: .5em;
padding-bottom: .5em;
}
The cells won't react to anything unless you set the border-collapse first. You can also add borders to TR elements once that's set (among other things.)
If this is for layout, I'd move to using DIVs and more up-to-date layout techniques, but if this is tabular data, knock yourself out. I still make heavy use of tables in my web applications for data.
Here is a function to get the IP address using a filter for local and LAN IP addresses:
function get_IP_address()
{
foreach (array('HTTP_CLIENT_IP',
'HTTP_X_FORWARDED_FOR',
'HTTP_X_FORWARDED',
'HTTP_X_CLUSTER_CLIENT_IP',
'HTTP_FORWARDED_FOR',
'HTTP_FORWARDED',
'REMOTE_ADDR') as $key){
if (array_key_exists($key, $_SERVER) === true){
foreach (explode(',', $_SERVER[$key]) as $IPaddress){
$IPaddress = trim($IPaddress); // Just to be safe
if (filter_var($IPaddress,
FILTER_VALIDATE_IP,
FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE)
!== false) {
return $IPaddress;
}
}
}
}
}
If you are still getting 127.0.0.1 as the IP, you need to add your "proxy", but be aware that you have to change it before going into production!
Read "Configuring Trusted Proxies".
And add this:
class TrustProxies extends Middleware
{
/**
* The trusted proxies for this application.
*
* @var array
*/
protected $proxies = '*';
Now request()->ip()
gives you the correct IP.
I found the it wonderful to cover multiple variants of date time format like this:
final DateTimeFormatterBuilder dtfb = new DateTimeFormatterBuilder();
dtfb.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SS"))
.appendOptional(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.S"))
.parseDefaulting(ChronoField.HOUR_OF_DAY, 0)
.parseDefaulting(ChronoField.MINUTE_OF_HOUR, 0)
.parseDefaulting(ChronoField.SECOND_OF_MINUTE, 0);
Found the solution as below.... posting it as it could help somebody else too :)
DateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date date = format.parse("2014-04-24 11:15:00");
GregorianCalendar cal = new GregorianCalendar();
cal.setTime(date);
XMLGregorianCalendar xmlGregCal = DatatypeFactory.newInstance().newXMLGregorianCalendar(cal);
System.out.println(xmlGregCal);
Output:
2014-04-24T11:15:00.000+02:00

forget all the answers, this line of CSS worked for me in 2 seconds :
height:100vh;
1vh
= 1% of browser screen height
For responsive layout scaling, you might want to use :
min-height: 100vh
[update november 2018] As mentionned in the comments, using the min-height might avoid having issues on reponsive designs
[update april 2018] As mentioned in the comments, back in 2011 when the question was asked, not all browsers supported the viewport units.
The other answers were the solutions back then -- vmax
is still not supported in IE, so this might not be the best solution for all yet.
You may try:
settings = s.merge_environment_settings(prepped.url, None, None, None, None)

An "em" is a typographical unit of width, the width of a wide-ish letter like "m" pronounced "em". Similarly there is an "en". Similarly "en-dash" and "em-dash" for – and —
I prefer using Hamcrest because it gives much better output in case of a failure
Assert.assertThat(listUnderTest,
IsIterableContainingInOrder.contains(expectedList.toArray()));
Instead of reporting
expected true, got false
it will report
expected List containing "1, 2, 3, ..." got list containing "4, 6, 2, ..."
IsIterableContainingInOrder.contain
According to the Javadoc:
Creates a matcher for Iterables that matches when a single pass over the examined Iterable yields a series of items, each logically equal to the corresponding item in the specified items. For a positive match, the examined iterable must be of the same length as the number of specified items
So the listUnderTest
must have the same number of elements and each element must match the expected values in order.
You can use the <datalist>
tag instead of the <select>
tag.
<input list="browsers" name="browser" id="browser">
<datalist id="browsers">
<option value="Edge">
<option value="Firefox">
<option value="Chrome">
<option value="Opera">
<option value="Safari">

DP size of any device is (actual resolution / density conversion factor).
Density conversion factor for density buckets are as follows:
ldpi: 0.75
mdpi: 1.0 (base density)
hdpi: 1.5
xhdpi: 2.0
xxhdpi: 3.0
xxxhdpi: 4.0
Examples of resolution/density conversion to DP:
ldpi device of 240 X 320 px will be of 320 X 426.66 DP. 240 / 0.75 = 320 dp 320 / 0.75 = 426.66 dp
xxhdpi device of 1080 x 1920 pixels (Samsung S4, S5) will be of 360 X 640 dp. 1080 / 3 = 360 dp 1920 / 3 = 640 dp
This image show more:
For more details about DIP read here.
I don't think you can do this with CSS. Instead, at regular 'word lengths' along the string, insert an HTML soft-hyphen:
ACTGATCG­AGCTGAAG­CGCAGTGC­GATGCTTC­GATGATGC­TGACGATG
This will display a hyphen at the end of the line, where it wraps, which may or may not be what you want.
Note Safari seems to wrap the long string in a <textarea>
anyway, unlike Firefox.
In latin1 each character is exactly one byte long. In utf8 a character can consist of more than one byte. Consequently utf8 has more characters than latin1 (and the characters they do have in common aren't necessarily represented by the same byte/bytesequence).
<script type="text/javascript"

// You may specify partial version numbers, such as "1" or "1.3",

But even he admits that it just doesn't compare to doing the following when it comes to optimal performance:
<script src="//ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.2.min.js" type="text/javascript"></script>

</html>
I got same situation in one of my Ajax calls, where JSON
was throwing an error due to the newline in the Textarea field. The solution given here didn't worked for me.
So i used Javascript's .escape
function and it worked fine. Then to retrieve the value from JSON
, I just unescaped using .unescape
.
As everyone else has pointed out, this can work:
<a href="newsletter_01.pdf" target="_blank">Read more</a>
But what nobody has pointed out is that it's not guaranteed to work.
There is no way to force a user's browser to open a PDF file in a new tab. Depending on the user's browser settings, even with target="_blank"
the browser may react the following ways:
Take a look at Firefox's settings, for example:
Chrome has a similar setting:
If the user has chosen to "Save File" in their browsers settings when encountering a PDF, there is no way you can override it.

You can find the Python executable with this command:
C:\> where python.exe
It should return something like:

Open regedit, navigate to HKEY_CURRENT_USER\SOFTWARE\Python\PythonCore\<version>\PythonPath
and add or edit the default key with this the value found in the first command.
Logout, login and python should be found. SciKit can now be installed.

In your current code, what Dictionary.update()
does is that it updates (update means the value is overwritten from the value for same key in passed in dictionary) the keys in current dictionary with the values from the dictionary passed in as the parameter to it (adding any new key:value pairs if existing) . A single flat dictionary does not satisfy your requirement , you either need a list of dictionaries or a dictionary with nested dictionaries.
If you want a list of dictionaries (where each element in the list would be a diciotnary of a entry) then you can make case_list
as a list and then append case
to it (instead of update) .
Example -
case_list = []
for entry in entries_list:
case = {'key1': entry[0], 'key2': entry[1], 'key3':entry[2] }
case_list.append(case)
Or you can also have a dictionary of dictionaries with the key of each element in the dictionary being entry1
or entry2
, etc and the value being the corresponding dictionary for that entry.
case_list = {}
for entry in entries_list:
case = {'key1': value, 'key2': value, 'key3':value }
case_list[entryname] = case #you will need to come up with the logic to get the entryname.
You should have a look at Boost.Python. Here is the short introduction taken from their website:
The Boost Python Library is a framework for interfacing Python and C++. It allows you to quickly and seamlessly expose C++ classes functions and objects to Python, and vice-versa, using no special tools -- just your C++ compiler. It is designed to wrap C++ interfaces non-intrusively, so that you should not have to change the C++ code at all in order to wrap it, making Boost.Python ideal for exposing 3rd-party libraries to Python. The library's use of advanced metaprogramming techniques simplifies its syntax for users, so that wrapping code takes on the look of a kind of declarative interface definition language (IDL).
In my case the problem was due to my forgetting to have annotated my Entity classes with @javax.persistence.Entity
annotation. Doh!
//The class reported as "not a amanaged type"
@javax.persistence.Entity
public class MyEntityClass extends my.base.EntityClass {
....
}
@Mark Rajcok gave a great solution for ion projects that include a range type input.
In any other case of non ion projects I will suggest this:
HTML:
<input type="text" name="points" #points maxlength="8" [(ngModel)]="range" (ngModelChange)="range=saverange($event, points)">
Component:
onChangeAchievement(eventStr: string, eRef): string {
//Do something (some manipulations) on input and than return it to be saved:
//In case you need to force of modifing the Element-Reference value on-focus of input:
var eventStrToReplace = eventStr.replace(/[^0-9,eE\.\+]+/g, "");
if (eventStr != eventStrToReplace) {
eRef.value = eventStrToReplace;
}
return this.getNumberOnChange(eventStr);
}
The idea here:
Letting the (ngModelChange)
method to do the Setter job:
(ngModelChange)="range=saverange($event, points)
Enabling direct access to the native Dom element using this call:
eRef.value = eventStrToReplace;

Edit: 2015-10-26: thanks for the upvotes - but take a look at tchrist's answer, especially if you develop for the web or something more "international".
Oren Trutners answer isn't quite right (see sample input of "RightHerE" which must be matched but isn't)
Here is the correct solution:
(?!^.*[A-Z]{2,}.*$)^[A-Za-z]*$
edit:
(?!^.*[A-Z]{2,}.*$) // don't match the whole expression if there are two or more consecutive uppercase letters
^[A-Za-z]*$ // match uppercase and lowercase letters

You can append a queryString to your src and change it only when you will release an updated version:
<script src="test.js?v=1"></script>
In this way the browser will use the cached version until a new version will be specified (v=2, v=3...)
You can also use numpy loadtxt like
from numpy import loadtxt
lines = loadtxt("filename.dat", comments="#", delimiter=",", unpack=False)
If you're willing to use std::string
s, you can use this sample-app's strsub
function as-is, or update it if you want it to take a different type or set of parameters to achieve roughly the same goal. Basically, it uses the properties and functionalities of std::string
to quickly erase the matching set of characters, and insert the desired characters directly within the std::string
. Every time it does this replacement operation, the offset updates if it can still find matching chars to replace, and if it can't due to nothing more to replace, it returns the string in its state from the last update.
#include <iostream>
#include <string>
std::string strsub(std::string stringToModify,
std::string charsToReplace,
std::string replacementChars);
int main()
{
std::string silly_typos = "annoiiyyyng syyyllii tiipos.";
std::cout << "Look at these " << silly_typos << std::endl;
silly_typos = strsub(silly_typos, "yyy", "i");
std::cout << "After a little elbow-grease, a few less " << silly_typos << std::endl;
silly_typos = strsub(silly_typos, "ii", "y");
std::cout << "There, no more " << silly_typos << std::endl;
return 0;
}
std::string strsub(std::string stringToModify,
std::string charsToReplace,
std::string replacementChars)
{
std::string this_string = stringToModify;
std::size_t this_occurrence = this_string.find(charsToReplace);
while (this_occurrence != std::string::npos)
{
this_string.erase(this_occurrence, charsToReplace.size());
this_string.insert(this_occurrence, replacementChars);
this_occurrence = this_string.find(charsToReplace,
this_occurrence + replacementChars.size());
}
return this_string;
}
If you don't want to rely on using std::string
s as your parameters so you can pass in C-style strings instead, you can see the updated sample below:
#include <iostream>
#include <string>
std::string strsub(const char * stringToModify,
const char * charsToReplace,
const char * replacementChars,
uint64_t sizeOfCharsToReplace,
uint64_t sizeOfReplacementChars);
int main()
{
std::string silly_typos = "annoiiyyyng syyyllii tiipos.";
std::cout << "Look at these " << silly_typos << std::endl;
silly_typos = strsub(silly_typos.c_str(), "yyy", "i", 3, 1);
std::cout << "After a little elbow-grease, a few less " << silly_typos << std::endl;
silly_typos = strsub(silly_typos.c_str(), "ii", "y", 2, 1);
std::cout << "There, no more " << silly_typos << std::endl;
return 0;
}
std::string strsub(const char * stringToModify,
const char * charsToReplace,
const char * replacementChars,
uint64_t sizeOfCharsToReplace,
uint64_t sizeOfReplacementChars)
{
std::string this_string = stringToModify;
std::size_t this_occurrence = this_string.find(charsToReplace);
while (this_occurrence != std::string::npos)
{
this_string.erase(this_occurrence, sizeOfCharsToReplace);
this_string.insert(this_occurrence, replacementChars);
this_occurrence = this_string.find(charsToReplace,
this_occurrence + sizeOfReplacementChars);
}
return this_string;
}
As far as I'm aware this is the only answer here that works correctly with spaces:
space:=
space+=
CURRENT_PATH := $(subst $(lastword $(notdir $(MAKEFILE_LIST))),,$(subst $(space),\$(space),$(shell realpath '$(strip $(MAKEFILE_LIST))')))
It essentially works by escaping space characters by substituting ' '
for '\ '
which allows Make to parse it correctly, and then it removes the filename of the makefile in MAKEFILE_LIST
by doing another substitution so you're left with the directory that makefile is in. Not exactly the most compact thing in the world but it does work.
You'll end up with something like this where all the spaces are escaped:
$(info CURRENT_PATH = $(CURRENT_PATH))
CURRENT_PATH = /mnt/c/Users/foobar/gDrive/P\ roje\ cts/we\ b/sitecompiler/
add this dependency https://mvnrepository.com/artifact/org.slf4j/slf4j-api/1.7.28

If you're set on using scanf
, you can do something like the following:
int val;
char follow;
int read = scanf( "%d%c", &val, &follow );
if ( read == 2 )
{
if ( isspace( follow ) )
{
// input is an integer followed by whitespace, accept
}
else
{
// input is an integer followed by non-whitespace, reject
}
}
else if ( read == 1 )
{
// input is an integer followed by EOF, accept
}
else
{
// input is not an integer, reject
}
I've adapted Nikhil's answer somewhat to simplify it. Admittedly, I have not run it through a .net compiler and there are likely very good reasons for the lines Nikhil put in which I have omitted. However, at least in my use case (a very simple page) they were unnecessary.
My use case was for a quick powershell script:
$htmlText = $(New-Object
System.Net.WebClient).DownloadString("<URI HERE>") #Get the HTML document from a webserver
$browser = New-Object System.Windows.Forms.WebBrowser
$browser.DocumentText = $htmlText
$browser.Document.Write($htmlText)
$response = $browser.document
For my case, this returned an HTMLDocument
object with HTMLElement
objects in it, instead of __ComObject
object types (which are a challenge to use in powershell class code) returned by a call to Invoke-WebRequest
in PS 5.1.14393.1944
I believe the equivalent C# code is:
public System.Windows.Forms.HtmlDocument GetHtmlDocument(string html)
{
WebBrowser browser = new WebBrowser();
browser.DocumentText = html;
browser.Document.Write(html);
return browser.Document;
}
To assign, you should use p=p+1;
instead of p+1=p;
int main()
{
int x[3]={4,5,6};
int *p=x;
p=p+1; /*You just needed to switch the terms around*/
cout<<p<<endl;
getch();
}
Iteration is a general term for taking each item of something, one after another. Any time you use a loop, explicit or implicit, to go over a group of items, that is iteration.
In Python, iterable and iterator have specific meanings.
An iterable is an object that has an __iter__
method which returns an iterator, or which defines a __getitem__
method that can take sequential indexes starting from zero (and raises an IndexError
when the indexes are no longer valid). So an iterable is an object that you can get an iterator from.
An iterator is an object with a next
(Python 2) or __next__
(Python 3) method.
Whenever you use a for
loop, or map
, or a list comprehension, etc. in Python, the next
method is called automatically to get each item from the iterator, thus going through the process of iteration.
A good place to start learning would be the iterators section of the tutorial and the iterator types section of the standard types page. After you understand the basics, try the iterators section of the Functional Programming HOWTO.
for me below worked:

TLDR; (semi-related to an EF editor bug in EF6/VS2012U5) if you generate the model from DB and you cannot see the attributed m:m table: Delete the two related tables -> Save .edmx -> Generate/add from database -> Save.
For those who came here wondering how to get a many-to-many relationship with attribute columns to show in the EF .edmx file (as it would currently not show and be treated as a set of navigational properties), AND you generated these classes from your database table (or database-first in MS lingo, I believe.)
Delete the 2 tables in question (to take the OP example, Member and Comment) in your .edmx and add them again through 'Generate model from database'. (i.e. do not attempt to let Visual Studio update them - delete, save, add, save)
It will then create a 3rd table in line with what is suggested here.
This is relevant in cases where a pure many-to-many relationship is added at first, and the attributes are designed in the DB later.
This was not immediately clear from this thread/Googling. So just putting it out there as this is link #1 on Google looking for the issue but coming from the DB side first.
On UNIX systems, you can use sigaction
call to register a signal handler for SIGINT
signal which represents the Control+C key sequence. The signal handler can set a flag which will be checked in the loop making it to break appropriately.
You could also try this:
<input type="submit" name="submitbutton1" value="submit1" />
<input type="submit" name="submitbutton2" value="submit2" />
Then in your default function you call the functions you want:
if( Request.Form["submitbutton1"] != null)
{
// Code for function 1
}
else if(Request.Form["submitButton2"] != null )
{
// code for function 2
}
Yes!! Got it!
I downloaded the Java Developer Kit (JDK) from sun.com for Linux. There was src.zip in. But first I uninstalled all Java packages with synaptic.
string[] lines = File.ReadAllLines(txtProxyListPath.Text);
// No need for the list
// List<string> list_lines = new List<string>(lines);
Parallel.ForEach(lines, line =>
{
//My Stuff
});
This will cause the lines to be parsed in parallel, within the loop. If you want a more detailed, less "reference oriented" introduction to the Parallel class, I wrote a series on the TPL which includes a section on Parallel.ForEach.
The brief points:
If the request header had already been set, then the new value MUST be concatenated to the existing value using a U+002C COMMA followed by a U+0020 SPACE for separation.
UAs MAY give the User-Agent header an initial value, but MUST allow authors to append values to it.
However - After searching through the framework XHR in jQuery they don't allow you to change the User-Agent or Referer headers. The closest thing:
// Set header so the called script knows that it's an XMLHttpRequest
xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest");
I'm leaning towards the opinion that what you want to do is being denied by a security policy in FF - if you want to pass some custom Referer
type header you could always do:
xhr.setRequestHeader('X-Alt-Referer', 'http://www.google.com');
The accepted answer is good. To extend on the last part:
Note that encodeURIComponent does not escape the ' character. A common bug is to use it to create html attributes such as href='MyUrl', which could suffer an injection bug. If you are constructing html from strings, either use " instead of ' for attribute quotes, or add an extra layer of encoding (' can be encoded as %27).
If you want to be on the safe side, percent encoding unreserved characters should be encoded as well.
You can use this method to escape them (source Mozilla)
function fixedEncodeURIComponent(str) {
return encodeURIComponent(str).replace(/[!'()*]/g, function(c) {
return '%' + c.charCodeAt(0).toString(16);
});
}
// fixedEncodeURIComponent("'") --> "%27"
Windows 8 (and likely 7 + Vista) also provide a view in Resource Monitor. If you select the Network tab, there's a section called 'Listening Ports'. Can sort by port number, and see which process is using it.
Here is a simple and very inelegant & potentially dangerous way.
I'm guessing that you are not doing log backups. (Which truncate the log). My advice is to change recovery model from full to simple. This will prevent log bloat.
I think, that in this case using PYTHONPATH is a better thing, mostly because it doesn't introduce (questionable) unneccessary code.
After all, if you think of it, your user doesn't need that sys.path
thing, because your package will get installed into site-packages, because you will be using a packaging system.
If the user chooses to run from a "local copy", as you call it, then I've observed, that the usual practice is to state, that the package needs to be added to PYTHONPATH manually, if used outside the site-packages.
Try this:
UPDATE business AS b
INNER JOIN business_geocode AS g ON b.business_id = g.business_id
SET b.mapx = g.latitude,
b.mapy = g.longitude
WHERE (b.mapx = '' or b.mapx = 0) and
g.latitude > 0
Since you said the query yielded a syntax error, I created some tables that I could test it against and confirmed that there is no syntax error in my query:
mysql> create table business (business_id int unsigned primary key auto_increment, mapx varchar(255), mapy varchar(255)) engine=innodb;
Query OK, 0 rows affected (0.01 sec)
mysql> create table business_geocode (business_geocode_id int unsigned primary key auto_increment, business_id int unsigned not null, latitude varchar(255) not null, longitude varchar(255) not null, foreign key (business_id) references business(business_id)) engine=innodb;
Query OK, 0 rows affected (0.01 sec)
mysql> UPDATE business AS b
-> INNER JOIN business_geocode AS g ON b.business_id = g.business_id
-> SET b.mapx = g.latitude,
-> b.mapy = g.longitude
-> WHERE (b.mapx = '' or b.mapx = 0) and
-> g.latitude > 0;
Query OK, 0 rows affected (0.00 sec)
Rows matched: 0 Changed: 0 Warnings: 0
See? No syntax error. I tested against MySQL 5.5.8.
SET @rownum = 0;
SELECT sub.*, sub.rank as Rank
FROM
(
SELECT *, (@rownum := @rownum + 1) as rank
FROM msgtable
WHERE cdate = '18/07/2012'
) sub
WHERE rank BETWEEN ((@PageNum - 1) * @PageSize + 1)
AND (@PageNum * @PageSize)
Every time you pass the parameters @PageNum
and the @PageSize
to get the specific page you want. For exmple the first 10 rows would be @PageNum = 1 and @PageSize = 10
There's a workaround for IE - use inline SVG and set pointer-events="none" in SVG. See my answer in How to make Internet Explorer emulate pointer-events:none?
A workaround is to use a willAnswer()
method.
For example the following works (and doesn't throw a MockitoException
but actually throws a checked Exception
as required here) using BDDMockito
:
given(someObj.someMethod(stringArg1)).willAnswer( invocation -> { throw new Exception("abc msg"); });
The equivalent for plain Mockito would to use the doAnswer
method
It's more of an aesthetics thing, much easier to read code where you explicitly know why the loop will stop right in the declaration of the loop.
Use:
android:imeActionLabel="Done"
android:singleLine="true"
This question has been already answered in Unicode characters in Windows command line - how?
You missed one step -> you need to use Lucida console fonts in addition to executing chcp 65001 from cmd console.
public void CopyStream(Stream stream, string destPath)
{
using (var fileStream = new FileStream(destPath, FileMode.Create, FileAccess.Write))
{
stream.CopyTo(fileStream);
}
}
I'd say the minimum would be to
Config file:
worker_processes 4; # 2 * Number of CPUs
events {
worker_connections 19000; # It's the key to high performance - have a lot of connections available
}
worker_rlimit_nofile 20000; # Each connection needs a filehandle (or 2 if you are proxying)
# Total amount of users you can serve = worker_processes * worker_connections

For Python 2.7+
, this works which makes the accepted answer slightly more readable:
sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)], key=lambda (k, val): val)
You could use a form styled as a link. No JavaScript is required:
<form action="/do/stuff.php" method="post">
<input type="hidden" name="user_id" value="123" />
<button>Go to user 123</button>
</form>
CSS:
button {
border: 0;
padding: 0;
display: inline;
background: none;
text-decoration: underline;
color: blue;
}
button:hover {
cursor: pointer;
}
Update with string interpolation in ES2015.
const num = 07734;
let numStringArr = `${num}`.split('').map(el => parseInt(el)); // [0, 7, 7, 3, 4]
It helps to group multiple statements into a single one so that a function-like macro can actually be used as a function. Suppose you have:
#define FOO(n) foo(n);bar(n)
and you do:
void foobar(int n) {
if (n)
FOO(n);
}
then this expands to:
void foobar(int n) {
if (n)
foo(n);bar(n);
}
Notice that the second call bar(n)
is not part of the if
statement anymore.
Wrap both into do { } while(0)
, and you can also use the macro in an if
statement.

If you take a look at JQuery, you can do something like:
<iframe id="my_iframe" ...></iframe>
$('#my_iframe').contents().find('html').html();
This is assuming that your iframe parent and child reside on the same server, due to the Same Origin Policy in Javascript.
This has been covered here quite well, but if you REALLY need even better performance than anything listed here, you can use this approach that uses strtok
.
$Names_Keys = [];
$Name = strtok(file_get_contents($file), "\n");
while ($Name !== false) {
$Names_Keys[$Name] = 0;
$Name = strtok("\n");
}
Note, this assumes your file is saved with \n
as the newline character (you can update that as need be), and it also stores the words/names/lines as the array keys instead of the values, so that you can use it as a lookup table, allowing the use of isset
(much, much faster), instead of in_array
.
Frank's answer is good but Firestore introduced array-contains
recently that makes it easier to do AND queries.
You can create a filters
field to add you filters. You can add as many values as you need. For example to filter by comedy and Jack Nicholson you can add the value comedy_Jack Nicholson
but if you also you want to by comedy and 2014 you can add the value comedy_2014
without creating more fields.
{
"movies": {
"movie1": {
"genre": "comedy",
"name": "As good as it gets",
"lead": "Jack Nicholson",
"year": 2014,
"filters": [
"comedy_Jack Nicholson",
"comedy_2014"
]
}
}
}
I think this is what should we exactly do: http://www.html5rocks.com/en/tutorials/casestudies/gopherwoord-studios-resizing-html5-games/
function resizeGame() {
var gameArea = document.getElementById('gameArea');
var widthToHeight = 4 / 3;
var newWidth = window.innerWidth;
var newHeight = window.innerHeight;
var newWidthToHeight = newWidth / newHeight;
if (newWidthToHeight > widthToHeight) {
newWidth = newHeight * widthToHeight;
gameArea.style.height = newHeight + 'px';
gameArea.style.width = newWidth + 'px';
} else {
newHeight = newWidth / widthToHeight;
gameArea.style.width = newWidth + 'px';
gameArea.style.height = newHeight + 'px';
}
gameArea.style.marginTop = (-newHeight / 2) + 'px';
gameArea.style.marginLeft = (-newWidth / 2) + 'px';
var gameCanvas = document.getElementById('gameCanvas');
gameCanvas.width = newWidth;
gameCanvas.height = newHeight;
}
window.addEventListener('resize', resizeGame, false);
window.addEventListener('orientationchange', resizeGame, false);
To import database from dump file (in this case called filename.sql)
use: mysql -u username -p password database_name < filename.sql
you are on Windows you will need to open CMD and go to directory where mysql.exe is installed. you are using WAMP server then this is usually located in: C:\wamp\bin\mysql\mysql5.5.8\bin (*note the version of mysql might be different)
So you will: cd C:\wamp\bin\mysql\mysql5.5.8\bin
and then execute one of the above commands. Final command like this
C:\wamp\bin\mysql\mysql5.5.8\bin>mysql -u rootss -p pwdroot testdatabasename < D:\test\Projects\test_demo_db.sql
Have you had a look at $routeProvider.when('/path',{ resolve:{...}
? It can make the promise approach a bit cleaner:
Expose a promise in your service:
app.service('MyService', function($http) {
var myData = null;
var promise = $http.get('data.json').success(function (data) {
myData = data;
});
return {
promise:promise,
setData: function (data) {
myData = data;
},
doStuff: function () {
return myData;//.getSomeData();
}
};
});
Add resolve
to your route config:
app.config(function($routeProvider){
$routeProvider
.when('/',{controller:'MainCtrl',
template:'<div>From MyService:<pre>{{data | json}}</pre></div>',
resolve:{
'MyServiceData':function(MyService){
// MyServiceData will also be injectable in your controller, if you don't want this you could create a new promise with the $q service
return MyService.promise;
}
}})
}):
Your controller won't get instantiated before all dependencies are resolved:
app.controller('MainCtrl', function($scope,MyService) {
console.log('Promise is now resolved: '+MyService.doStuff().data)
$scope.data = MyService.doStuff();
});
I've made an example at plnkr: http://plnkr.co/edit/GKg21XH0RwCMEQGUdZKH?p=preview
In general, vim is a very powerful regular language editor (macros extend this but we'll ignore that for now). This is because vim's a thin layer on top of ed, and ed isn't much more than a line editor that speaks regex. Emacs has the advantage of being built on top of ELisp; lending it the ability to easily parse complex grammars and perform indentation tricks like the one you shared above.
To be honest, I've never been able to dive into the depths of emacs because it is simply delightful meditating within my vim cave. With that said, let's jump in.
Janus
For beginners, I highly recommend installing the readymade Janus plugin (fwiw, the name hails from a Star Trek episode featuring Janus Vim). If you want a quick shortcut to a vim IDE it's your best bang for your buck.
I've never used it much, but I've seen others use it happily and my current setup is borrowed heavily from an old Janus build.
Vim Pathogen
Otherwise, do some exploring on your own! I'd highly recommend installing vim pathogen if you want to see the universe of vim plugins.
It's a package manager of sorts. Once you install it, you can git clone
packages to your ~/.vim/bundle
directory and they're auto-installed. No more plugin installation, maintenance, or uninstall headaches!
You can run the following script from the GitHub page to install pathogen:
mkdir -p ~/.vim/autoload ~/.vim/bundle; \
curl -so ~/.vim/autoload/pathogen.vim \
https://raw.github.com/tpope/vim-pathogen/HEAD/autoload/pathogen.vim
Here are some links on extending vim I've found and enjoyed:
Try trimming the string to make sure there is no extra white space:
Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);
Also use c.moveToFirst()
like @thinksteep mentioned.
This is a complete code for select statements.
SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
do {
// Passing values
String column1 = c.getString(0);
String column2 = c.getString(1);
String column3 = c.getString(2);
// Do something Here with values
} while(c.moveToNext());
}
c.close();
db.close();
It works, but I wouldn't do it if I were you. You don't seem to be deleting that heap data when you're done, which means that you've created a memory leak. The C++ compiler takes care of ensuring that exception data is kept alive even as the stack is popped, so don't feel that you need to use the heap.
Incidentally, throwing a std::string
isn't the best approach to begin with. You'll have a lot more flexibility down the road if you use a simple wrapper object. It may just encapsulate a string
for now, but maybe in future you will want to include other information, like some data which caused the exception or maybe a line number (very common, that). You don't want to change all of your exception handling in every spot in your code-base, so take the high road now and don't throw raw objects.
First check out config files for syntax errors with apachectl configtest
and then look into apache error logs.
Using an ORDER BY
in a subquery is not the best solution to this problem.
The best solution to get the max(post_date)
by author is to use a subquery to return the max date and then join that to your table on both the post_author
and the max date.
The solution should be:
SELECT p1.*
FROM wp_posts p1
INNER JOIN
(
SELECT max(post_date) MaxPostDate, post_author
FROM wp_posts
WHERE post_status='publish'
AND post_type='post'
GROUP BY post_author
) p2
ON p1.post_author = p2.post_author
AND p1.post_date = p2.MaxPostDate
WHERE p1.post_status='publish'
AND p1.post_type='post'
order by p1.post_date desc
If you have the following sample data:
CREATE TABLE wp_posts
(`id` int, `title` varchar(6), `post_date` datetime, `post_author` varchar(3))
;
INSERT INTO wp_posts
(`id`, `title`, `post_date`, `post_author`)
VALUES
(1, 'Title1', '2013-01-01 00:00:00', 'Jim'),
(2, 'Title2', '2013-02-01 00:00:00', 'Jim')
;
The subquery is going to return the max date and author of:
MaxPostDate | Author
2/1/2013 | Jim
Then since you are joining that back to the table, on both values you will return the full details of that post.
See SQL Fiddle with Demo.
To expand on my comments about using a subquery to accurate return this data.
MySQL does not force you to GROUP BY
every column that you include in the SELECT
list. As a result, if you only GROUP BY
one column but return 10 columns in total, there is no guarantee that the other column values which belong to the post_author
that is returned. If the column is not in a GROUP BY
MySQL chooses what value should be returned.
Using the subquery with the aggregate function will guarantee that the correct author and post is returned every time.
As a side note, while MySQL allows you to use an ORDER BY
in a subquery and allows you to apply a GROUP BY
to not every column in the SELECT
list this behavior is not allowed in other databases including SQL Server.
