If you are using a pycharm IDE for development and you already have added Git with it. you can directly delete remote branch from pycharm. From toolbar VCS-->Git-->Branches-->Select branch-->and Delete. It will delete it from remote git server.
From the man read:
#include <unistd.h>
ssize_t read(int fd, void *buf, size_t count);
Input parameters:
int fd
file descriptor is an integer and not a file pointer. The file descriptor for stdin
is 0
void *buf
pointer to buffer to store characters read by the read
function
size_t count
maximum number of characters to read
So you can read character by character with the following code:
char buf[1];
while(read(0, buf, sizeof(buf))>0) {
// read() here read from stdin charachter by character
// the buf[0] contains the character got by read()
....
}
I know this is quite old, but when a lost stranger finds this question looking for an answer (like I did) then this is the best way to do it, instead of using removeAttr():
$element.prop("onclick", null);
Citing jQuerys official doku:
"Removing an inline onclick event handler using .removeAttr() doesn't achieve the desired effect in Internet Explorer 6, 7, or 8. To avoid potential problems, use .prop() instead"
CustomFragment dialog = (CustomDataFragment) getSupportFragmentManager().findFragmentByTag("Fragment_TAG");
if (dialog != null) {
dialog.dismiss();
}
You would have to watch the DOM node changes. There is an API called MutationObserver
, but it looks like the support for it is very limited. This SO answer has a link to the status of the API, but it seems like there is no support for it in IE or Opera so far.
One way you could get around this problem is to have the part of the code that modifies the data-select-content-val
attribute dispatch an event that you can listen to.
For example, see: http://jsbin.com/arucuc/3/edit on how to tie it together.
The code here is
$(function() {
// Here you register for the event and do whatever you need to do.
$(document).on('data-attribute-changed', function() {
var data = $('#contains-data').data('mydata');
alert('Data changed to: ' + data);
});
$('#button').click(function() {
$('#contains-data').data('mydata', 'foo');
// Whenever you change the attribute you will user the .trigger
// method. The name of the event is arbitrary
$(document).trigger('data-attribute-changed');
});
$('#getbutton').click(function() {
var data = $('#contains-data').data('mydata');
alert('Data is: ' + data);
});
});
you must check is user loggined ?
Auth::check() ? Auth::user()->id : null
Note that connection strings are specific to what and how you are connecting to data. These are connecting to the same database but the first is using .NET Framework Data Provider for SQL Server. Integrated Security=True will not work for OleDb.
When in doubt use the Visual Studio Server Explorer Data Connections.
Thanks to duncan answer, I end up with this:
marker.addListener('mouseover', () => infoWindow.open(map, marker))
marker.addListener('mouseout', () => infoWindow.close())
My own solution on Linux (under ~/.config/smartgit/19.1
) is to comment or remove line listx
from preferences.yml
file and reopen program.
Deleting the all folders will make you reconfigure everything (useless).
I get this a lot. I'm on a Galaxy S too. I unplug the cable from the phone, plug it back in and try launching the app again from Eclipse, and it usually does the trick. Eclipse seems to lose the connection to the phone occasionally but this seems to kick it back to life.
As error message said your application has no permissions to read from the directory. It can be the case when you created the directory as one user and run script as another user.
This is an example of using the :checked
pseudo-class to make forms more accessible. The :checked
pseudo-class can be used with hidden inputs and their visible labels to build interactive widgets, such as image galleries. I created the snipped for the people that wanna test.
input[type=checkbox] + label {_x000D_
color: #ccc;_x000D_
font-style: italic;_x000D_
} _x000D_
input[type=checkbox]:checked + label {_x000D_
color: #f00;_x000D_
font-style: normal;_x000D_
}
_x000D_
<input type="checkbox" id="cb_name" name="cb_name"> _x000D_
<label for="cb_name">CSS is Awesome</label>
_x000D_
Have a look at the add
filter.
Edit: You can chain filters, so you could do "shop/"|add:shop_name|add:"/base.html"
. But that won't work because it is up to the template tag to evaluate filters in arguments, and extends doesn't.
I guess you can't do this within templates.
Thanks to everyone for responding so fast. Joel, I used your option 2 and added a registry key to the "Run" folder of the current user. Here's the code I used for anyone else who's interested.
using Microsoft.Win32;
private void SetStartup()
{
RegistryKey rk = Registry.CurrentUser.OpenSubKey
("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true);
if (chkStartUp.Checked)
rk.SetValue(AppName, Application.ExecutablePath);
else
rk.DeleteValue(AppName,false);
}
You need to write it this way
<div
className="player"
style={{ position: "absolute" }}
onKeyDown={this.onKeyPressed}
tabIndex="0"
>
If onKeyPressed
is not bound to this
, then try to rewrite it using arrow function or bind it in the component constructor
.
MediaRecorder API is the solution you are looking for,
Firefox has been supporting it for some time now, and the buzz is is Chrome is gonna implement it in its next release (Chrome 48), but guess you still might need to enable the experimental flag, apparently the flag won't be need from Chrome version 49, for more info check out this Chrome issue.
Meanwhile, a sample of how to do it in Firefox:
var video, reqBtn, startBtn, stopBtn, ul, stream, recorder;
video = document.getElementById('video');
reqBtn = document.getElementById('request');
startBtn = document.getElementById('start');
stopBtn = document.getElementById('stop');
ul = document.getElementById('ul');
reqBtn.onclick = requestVideo;
startBtn.onclick = startRecording;
stopBtn.onclick = stopRecording;
startBtn.disabled = true;
ul.style.display = 'none';
stopBtn.disabled = true;
function requestVideo() {
navigator.mediaDevices.getUserMedia({
video: true,
audio: true
})
.then(stm => {
stream = stm;
reqBtn.style.display = 'none';
startBtn.removeAttribute('disabled');
video.src = URL.createObjectURL(stream);
}).catch(e => console.error(e));
}
function startRecording() {
recorder = new MediaRecorder(stream, {
mimeType: 'video/mp4'
});
recorder.start();
stopBtn.removeAttribute('disabled');
startBtn.disabled = true;
}
function stopRecording() {
recorder.ondataavailable = e => {
ul.style.display = 'block';
var a = document.createElement('a'),
li = document.createElement('li');
a.download = ['video_', (new Date() + '').slice(4, 28), '.webm'].join('');
a.href = URL.createObjectURL(e.data);
a.textContent = a.download;
li.appendChild(a);
ul.appendChild(li);
};
recorder.stop();
startBtn.removeAttribute('disabled');
stopBtn.disabled = true;
}

If you need digits (after separator), you can simply split number and count length second part (after point).
function countDigits(number) {
var sp = (number + '').split('.');
if (sp[1] !== undefined) {
return sp[1].length;
} else {
return 0;
}
}
Most Simpler Way From My Side is to Add a variable in adapterPage as last Clicked Position.
in onBindViewHolder paste this code which checks for last stored position matched with loading positions Constants is the class where i declare my global variables
if(Constants.LAST_SELECTED_POSITION_SINGLE_PRODUCT == position) {
//change the view background here
holder.colorVariantThumb.setBackgroundResource(R.drawable.selected_background);
}
//on view click you store the position value and notifyItemRangeChanged will
// call the onBindViewHolder and will check the condition
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view){
Constants.LAST_SELECTED_POSITION_SINGLE_PRODUCT=position;
notifyItemRangeChanged(0, mColorVariants.size());
}
});
For windows: just change file association of .js
file to node.exe
1) Take VSCode
2) Right click on the file in left pane
3) Click "Reveal in explorer" from context menu
4) Right click on the file -> Select "Open with" -> Select "Choose another program"
5) Check box "Always use this app to open .js file"
6) Click "More apps" -> "Look for another app in PC"
7) Navigate to node.js installation directory.(Default C:\Program Files\nodejs\node.exe"
8) Click "Open" and you can just see cmd flashing
9) Restart vscode and open the file -> Terminal Menu -> "Run active file".
You can also check for bootstrap datatable plugin as well for above issue.
It will have a large column table scrollable feature with lot of other options
$(document).ready(function() {
$('#example').dataTable( {
"scrollX": true
} );
} );

How about this?
$day_of_week = date('N', strtotime($string_date));
$week_first_day = date('Y-m-d', strtotime($string_date . " - " . ($day_of_week - 1) . " days"));
$week_last_day = date('Y-m-d', strtotime($string_date . " + " . (7 - $day_of_week) . " days"));
Found this thread while looking for a way to generate localized but short dates in all browsers without any extra library, just a simple call to format server generated ISO dates.
I went with a combination of holden321 and mwrf's answers. Storing the formats external to the function because it's handier that way and storing the current locale format because it's always useful.
The function can be passed anything that can be passed to a date constructor to get a valid date, and also a language or format for flexibility.
You need to set up the list of formats and a couple more things first:
var LOCALE_DATE_FORMATS = {
// as per mwrf's list
...
}
var LANG = window.navigator.userLanguage || window.navigator.language;
var LOCALE_DATE_FORMAT = LOCALE_DATE_FORMATS[LANG] || 'dd/MM/yyyy';
Then the function is:
function getLocalizedDate(o, options)
{
var res = '';
var date = new Date(o);
if(o != null && !isNaN(date) && typeof(date.getFullYear) == 'function')
{
var d = date.getDate();
var dd = d < 10 ? '0' + d : d;
var M = date.getMonth() + 1;
var MM = M < 10 ? '0' + M : M;
var yyyy = date.getFullYear();
var yy = new String(yyyy).substring(2);
var format = LOCALE_DATE_FORMAT;
if(options && options.lang)
format = LOCALE_DATE_FORMATS[options.lang];
else if(options && options.format)
format = options.format;
res = format
.replace(/dd/g, dd)
.replace(/d/g, d)
.replace(/MM/g, MM)
.replace(/M/g, M)
.replace(/yyyy/g, yyyy)
.replace(/yy/g, yy);
}
return res;
}
getLocalizedDate('2013-03-01T00:00:00', {lang:'sk-SK'})
= 1. 3. 2013
EDIT: Call with no arguments to use the user's locale, of course:
getLocalizedDate('2013-03-01T00:00:00')
= 01/03/2013
(for me)
If you are a fan of extending prototypes, the first lines of the function definition become:
Date.prototype.getLocalized = function(options)
{
var date = this;
Called of course like this:
new Date('2013-03-01T00:00:00').getLocalized({lang:'sk-SK'})
= 1. 3. 2013
EDIT: Again, call with no arguments to use the user's locale:
new Date('2013-03-01T00:00:00').getLocalized()
= 01/03/2013
(for me)
The problems here are to do with the npm node-gyp module
I found the solutions offered on the build page for that project effective.
There's a fully automatic way and a manual way.
package main
import "fmt"
import "strconv"
func FloatToString(input_num float64) string {
// to convert a float number to a string
return strconv.FormatFloat(input_num, 'f', 6, 64)
}
func main() {
fmt.Println(FloatToString(21312421.213123))
}
If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg
strconv.FormatFloat(input_num, 'f', -1, 64)
Personally I find fmt
easier to use. (Playground link)
fmt.Printf("x = %.6f\n", 21312421.213123)
Or if you just want to convert the string
fmt.Sprintf("%.6f", 21312421.213123)
I had a coworker ask how to do this today, and this is what I came up with. I don't love it but it is a way to do it without js and have headers respected. The main drawback however is you lose some semantics due to not having a true table header anymore.
Basically I wrap a table within a table, and use a div as the scroll container by giving it a max-height
. Since I wrap the table in a parent table "colspanning" the fake header rows it appears as if the table respects them, but in reality the child table just has the same number of rows.
One small issue due to the scroll bar taking up space the child table column widths wont match up exactly.
Markup
<table class="table-container">
<tbody>
<tr>
<td>header col 1</td>
<td>header col 2</td>
</tr>
<tr>
<td colspan="2">
<div class="scroll-container">
<table>
<tr>
<td>entry1</td>
<td>entry1</td>
</tr>
........ all your entries
</table>
</div>
</td>
</tr>
</tbody>
</table>
CSS
.table-container {
border:1px solid #ccc;
border-radius: 3px;
width:50%;
}
.table-container table {
width: 100%;
}
.scroll-container{
max-height: 150px;
overflow-y: scroll;
}
Even better are f-strings in python 3!
f = open(f'{name}.csv', 'wb')
For those who want isoWeek
to be the default you can modify moment's behaviour as such:
const moment = require('moment');
const proto = Object.getPrototypeOf(moment());
const {startOf, endOf} = proto;
proto.startOf = function(period) {
if (period === 'week') {
period = 'isoWeek';
}
return startOf.call(this, period);
};
proto.endOf = function(period) {
if (period === 'week') {
period = 'isoWeek';
}
return endOf.call(this, period);
};
Now you can simply use someDate.startOf('week')
without worrying you'll get sunday or having to think about whether to use isoweek
or isoWeek
etc.
Plus you can store this in a variable like const period = 'week'
and use it safely in subtract()
or add()
operations, e.g. moment().subtract(1, period).startOf(period);
. This won't work with period being isoWeek
.
Thanks above all of you contributions! however for my case I finally realized that my dependency above "spring-web" was destroyed on my .m2/repository/org/springframework/spring-web, I just deleted the folder and update Maven again. it got fixed.
So if your scenario is that you've committed to master
but meant to commit to another-branch
(which may or not may not already exist) but you haven't pushed yet, this is pretty easy to fix.
// if your branch doesn't exist, then add the -b argument
git checkout -b another-branch
git branch --force master origin/master
Now all your commits to master
will be on another-branch
.

Find this useful solution
function get_duplicates( $array ) {
return array_unique( array_diff_assoc( $array, array_unique( $array ) ) );
}
After that count result if greater than 0 than duplicates else unique.
Problem solved, I've not added the index.html. Which is point out in the web.xml
Note: a project may have more than one web.xml file.
if there are another web.xml in
src/main/webapp/WEB-INF
Then you might need to add another index (this time index.jsp) to
src/main/webapp/WEB-INF/pages/
I might be late. Simply add a new field ID in the table with type AutoNumber. This will generate unique IDs and can utilize in Access too
Looks like the question has been long ago answered but the solution did not work for me. When I was getting that error, I was able to fix the problem by downloading PyWin32
Fixed my issue by writing print (sys.path)
and found out that python was using out of date packages despite a clean install. Deleting these made python automatically use the correct packages.
In Fedora 21 and up, you simply open a terminal and install the Ruby Development files as root.
dnf install ruby-devel
getline is storing the entire line at once, which is not what you want. A simple fix is to have three variables and use cin to get them all. C++ will parse automatically at the spaces.
#include <iostream>
using namespace std;
int main() {
string a, b, c;
cin >> a >> b >> c;
//now you have your three words
return 0;
}
I don't know what particular "operation" you're talking about, so I can't help you there, but if it's changing characters, read up on string and indices. The C++ documentation is great. As for using namespace std; versus std:: and other libraries, there's already been a lot said. Try these questions on StackOverflow to start.
For setting the Socket timeout, you need to follow these steps:
import socket
socks = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socks.settimeout(10.0) # settimeout is the attr of socks.
The following should work:
from matplotlib import pyplot as plt
plt.imshow(data, interpolation='nearest')
plt.show()
If you are using Jupyter notebook/lab, use this inline command before importing matplotlib:
%matplotlib inline
To obtain a stream of just the names:
$ jq '.[] | select(.location=="Stockholm") | .name' json
produces:
"Donald"
"Walt"
To obtain a stream of corresponding (key name, "name" attribute) pairs, consider:
$ jq -c 'to_entries[]
| select (.value.location == "Stockholm")
| [.key, .value.name]' json
Output:
["FOO","Donald"]
["BAR","Walt"]
I was able to solve the issue by granting complete s3 access to Lambda from policies. Make a new role for Lambda and attach the policy with complete S3 Access to it.
Hope this will help.
Beautiful Soup 4 allows you to set a formatter to your output
If you pass in
formatter=None
, Beautiful Soup will not modify strings at all on output. This is the fastest option, but it may lead to Beautiful Soup generating invalid HTML/XML, as in these examples:
print(soup.prettify(formatter=None))
# <html>
# <body>
# <p>
# Il a dit <<Sacré bleu!>>
# </p>
# </body>
# </html>
link_soup = BeautifulSoup('<a href="http://example.com/?foo=val1&bar=val2">A link</a>')
print(link_soup.a.encode(formatter=None))
# <a href="http://example.com/?foo=val1&bar=val2">A link</a>
You can use the following
new java.sql.Timestamp(System.currentTimeMillis()).getTime()
Result : 1539594988651

There are several reasons as to why this wouldn't work.
It is possible that matplotlib is not properly installed. have you tried running:
conda install matplotlib
If that doesn't work, look at your %PATH% environment variable, does it contain your libraries and python paths?
Here is a simple example, all it does is overlay an image (with whatever wording you want). I saw this technique somewhere. I am using the prototype library so you would need to modify if using something else. With the image loading after window.load it fails gracefully if javascript is disabled.

To understand it in a easier way, following are the diffrences between JSON object and JSON array:
Link to Tabular Difference : https://i.stack.imgur.com/GIqI9.png
JSON Array
1. Arrays in JSON are used to organize a collection of related items
(Which could be JSON objects)
2. Array values must be of type string, number, object, array, boolean or null
3. Syntax:
[ "Ford", "BMW", "Fiat" ]
4. JSON arrays are surrounded by square brackets [].
**Tip to remember** : Here, order of element is important. That means you have
to go straight like the shape of the bracket i.e. straight lines.
(Note :It is just my logic to remember the shape of both.)
5. Order of elements is important. Example: ["Ford","BMW","Fiat"] is not
equal to ["Fiat","BMW","Ford"]
6. JSON can store nested Arrays that are passed as a value.
JSON Object
1. JSON objects are written in key/value pairs.
2. Keys must be strings, and values must be a valid JSON data type (string, number,
object, array, boolean or null).Keys and values are separated by a colon.
Each key/value pair is separated by a comma.
3. Syntax:
{ "name":"Somya", "age":25, "car":null }
4. JSON objects are surrounded by curly braces {}
Tip to remember : Here, order of element is not important. That means you can go
the way you like. Therefore the shape of the braces i.e. wavy.
(Note : It is just my logic to remember the shape of both.)
5. Order of elements is not important.
Example: { rollno: 1, firstname: 'Somya'}
is equal to
{ firstname: 'Somya', rollno: 1}
6. JSON can store nested objects in JSON format in addition to nested arrays.
Use Python:
#!/bin/bash
# home/victoria/test.sh
START=$(date +"%s") ## seconds since Epoch
for i in $(seq 1 10)
do
sleep 1.5
END=$(date +"%s") ## integer
TIME=$((END - START)) ## integer
AVG_TIME=$(python -c "print(float($TIME/$i))") ## int to float
printf 'i: %i | elapsed time: %0.1f sec | avg. time: %0.3f\n' $i $TIME $AVG_TIME
((i++)) ## increment $i
done
Output
$ ./test.sh
i: 1 | elapsed time: 1.0 sec | avg. time: 1.000
i: 2 | elapsed time: 3.0 sec | avg. time: 1.500
i: 3 | elapsed time: 5.0 sec | avg. time: 1.667
i: 4 | elapsed time: 6.0 sec | avg. time: 1.500
i: 5 | elapsed time: 8.0 sec | avg. time: 1.600
i: 6 | elapsed time: 9.0 sec | avg. time: 1.500
i: 7 | elapsed time: 11.0 sec | avg. time: 1.571
i: 8 | elapsed time: 12.0 sec | avg. time: 1.500
i: 9 | elapsed time: 14.0 sec | avg. time: 1.556
i: 10 | elapsed time: 15.0 sec | avg. time: 1.500

I was solving this algorithm and get stuck with the pairs part.
This explanation help me a lot https://betterexplained.com/articles/techniques-for-adding-the-numbers-1-to-100/
So to calculate the sum of series of numbers:
n(n+1)/2
But you need to calculate this
1 + 2 + ... + (n-1)
So in order to get this you can use
n(n+1)/2 - n
that is equal to
n(n-1)/2
var array = searchTerms.split(",");
for (var i in array){
alert(array[i]);
}
You need to move type parameter to the method level to indicate that you have a generic method rather than generic class:
public class ArrayUtils {
public static <T> E[] appendToArray(E[] array, E item) {
E[] result = (E[])new Object[array.length+1];
result[array.length] = item;
return result;
}
}
Perhaps you don't have to include the single quotes:
curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/&fileName=1.doc"
Update: Reading curl's manual, you could actually separate both fields with two --data:
curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/" --data "fileName=1.doc"
You could also try --data-binary:
curl --request POST 'http://localhost/Service' --data-binary "path=/xyz/pqr/test/" --data-binary "fileName=1.doc"
And --data-urlencode:
curl --request POST 'http://localhost/Service' --data-urlencode "path=/xyz/pqr/test/" --data-urlencode "fileName=1.doc"
Just check your preinstall scripts if you have one. Sometimes to restrict the versions of node
and npm
one needs to run a project.
If that's the case you need to install semver
manually via npm install -g semver

androidx.localbroadcastmanager
is being deprecated in version 1.1.0
Reason
LocalBroadcastManager
is an application-wide event bus and embraces layer violations in your app; any component may listen to events from any other component.
It inherits unnecessary use-case limitations of system BroadcastManager; developers have to use Intent even though objects live in only one process and never leave it. For this same reason, it doesn’t follow feature-wise BroadcastManager .
These add up to a confusing developer experience.
Replacement
You can replace usage of LocalBroadcastManager
with other implementations of the observable pattern. Depending on your use case, suitable options may be LiveData
or reactive streams.
Advantage of LiveData
You can extend a LiveData
object using the singleton pattern to wrap system services so that they can be shared in your app. The LiveData
object connects to the system service once, and then any observer that needs the resource can just watch the LiveData
object.
public class MyFragment extends Fragment {
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
LiveData<BigDecimal> myPriceListener = ...;
myPriceListener.observe(this, price -> {
// Update the UI.
});
}
}
The observe()
method passes the fragment, which is an instance of LifecycleOwner
, as the first argument. Doing so denotes that this observer is bound to the Lifecycle
object associated with the owner, meaning:
If the Lifecycle object is not in an active state, then the observer isn't called even if the value changes.
After the Lifecycle object is destroyed, the observer is automatically removed
The fact that LiveData
objects are lifecycle-aware means that you can share them between multiple activities, fragments, and services.
There are several ways you can achieve this based on the approach you take. For reactive approach, you can pass the default value to the constructor of the FormControl(import from @angular/forms)
this.randomForm = new FormGroup({
'amateur': new FormControl(false),
});
Instead of true or false value, yes you can send variable name as well like FormControl(this.booleanVariable)
In template driven approach you can use 1 way binding [ngModel]="this.booleanVariable"
or 2 way binding [(ngModel)]="this.booleanVariable"
like this
<mat-checkbox
name="controlName"
[(ngModel)]="booleanVariable">
{{col.title}}
</mat-checkbox>
You can also use the checked directive provided by angular material and bind in similar manner
Like Ray Toal mentioned it is as easy as:
Set<String> myConcurrentSet = ConcurrentHashMap.newKeySet();
Another way do do this is to position your anchors exactly where you want on the page rather than relying on scrolling by offset. I find it allows better control for each element (eg. if you want a different offset for certain elements), and may also be more resistant to browser API changes/differences.
<div id="title-element" style="position: relative;">
<div id="anchor-name" style="position: absolute; top: -100px; left: 0"></div>
</div>
Now the offset is specified as -100px relative to the element. Create a function to create this anchor for code reuse, or if you are using a modern JS framework such as React do this by creating a component that renders your anchor, and pass in the anchor name and alignment for each element, which may or may not be the same.
Then just use :
const element = document.getElementById('anchor-name')
element.scrollIntoView({ behavior: 'smooth', block: 'start' });
For smooth scrolling with an offset of 100px.
This has already been answered, but I think the simplest syntax is:
CREATE TABLE History (
ID int primary key IDENTITY(1,1) NOT NULL,
. . .
The more complicated constraint index is useful when you actually want to change the options.
By the way, I prefer to name such a column HistoryId, so it matches the names of the columns in foreign key relationships.
I was facing the similar issue when using the Channel Factory. it was actually due to wrong Contract specified in the endpoint.
JObject implements IDictionary, so you can use it that way. For ex,
var cycleJson = JObject.Parse(@"{""name"":""john""}");
//add surname
cycleJson["surname"] = "doe";
//add a complex object
cycleJson["complexObj"] = JObject.FromObject(new { id = 1, name = "test" });
So the final json will be
{
"name": "john",
"surname": "doe",
"complexObj": {
"id": 1,
"name": "test"
}
}
You can also use dynamic
keyword
dynamic cycleJson = JObject.Parse(@"{""name"":""john""}");
cycleJson.surname = "doe";
cycleJson.complexObj = JObject.FromObject(new { id = 1, name = "test" });
This is the first time I really got stuck on freecodecamp. I perused through some solutions here and was amazed at how different they all were. Here is what ended up working for me.
function convertToRoman(num) {
var roman = "";
var lookupObj = {
1000:"M",
900:"CM",
500:"D",
400:"CD",
100:"C",
90:"XC",
50:"L",
40:"XL",
10:"X",
9:"IX",
4:"IV",
5:"V",
1:"I",
};
var arrayLen = Object.keys(lookupObj).length;
while(num>0){
for (i=arrayLen-1 ; i>=0 ; i--){
if(num >= Object.keys(lookupObj)[i]){
roman = roman + lookupObj[Object.keys(lookupObj)[i]];
num = num - Object.keys(lookupObj)[i];
break;
}
}
}
return roman;
}
convertToRoman(1231);
Use this code is whork :
if (!preg_match('#^http(s)?://#', $url)) {
$url = 'http://' . $url;
}
$urlParts = parse_url($url);
$url = preg_replace('/^www\./', '', $urlParts['host']);
You can declare like one of the below options:
char data[] = "Testing String";
or
const char* data = "Testing String";
or
char* data = (char*) "Testing String";
try this
Object.keys(data).length
If IE < 9, you can loop through the object yourself with a for loop
var len = 0;
var i;
for (i in data) {
if (data.hasOwnProperty(i)) {
len++;
}
}
You may try this:
foreach(var item in yourArray)
{
Console.WriteLine(item.ToString());
}
Also you may want to try something like this:
yourArray.ToList().ForEach(i => Console.WriteLine(i.ToString()));
EDIT: to get output in one line [based on your comment]:
Console.WriteLine("[{0}]", string.Join(", ", yourArray));
//output style: [8, 1, 8, 8, 4, 8, 6, 8, 8, 8]
EDIT(2019): As it is mentioned in other answers it is better to use Array.ForEach<T>
method and there is no need to do the ToList
step.
Array.ForEach(yourArray, Console.WriteLine);

I asked in #machomebrew and learned that you can switch between versions using brew switch.
$ brew switch libfoo mycopy
to get version mycopy of libfoo.
exit(X)
, where X is a number (according to the doc) should work.
But it is not recommended by Apple and won't be accepted by the AppStore.
Why? Because of these guidelines (one of my app got rejected):
We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.
Please refer to the attached screenshot/s for reference.
The iOS Human Interface Guidelines specify,
"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:
Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.
Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."
> It would be appropriate to remove any mechanisms for quitting your app.
Plus, if you try to hide that function, it would be understood by the user as a crash.
Simplest of all solutions:
filtered_df = df[df['name'].notnull()]
Thus, it filters out only rows that doesn't have NaN values in 'name' column.
For multiple columns:
filtered_df = df[df[['name', 'country', 'region']].notnull().all(1)]

It is possible to do everything you want. Aaron's answer was not quite complete.
His approach is correct, up to creating the temporary table in the inner query. Then, you need to insert the results into a table in the outer query.
The following code snippet grabs the first line of a file and inserts it into the table @Lines:
declare @fieldsep char(1) = ',';
declare @recordsep char(1) = char(10);
declare @Lines table (
line varchar(8000)
);
declare @sql varchar(8000) = '
create table #tmp (
line varchar(8000)
);
bulk insert #tmp
from '''+@filename+'''
with (FirstRow = 1, FieldTerminator = '''+@fieldsep+''', RowTerminator = '''+@recordsep+''');
select * from #tmp';
insert into @Lines
exec(@sql);
select * from @lines

You can also do:
export type UserEvent = Event & { UserId: string; };
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
String FilePath = "/home/lahiru/Desktop/Sample.xls";
FileInputStream fs = new FileInputStream(FilePath);
Workbook wb = Workbook.getWorkbook(fs);
String <variable> = sh.getCell("A2").getContents();
Just reading the file into an array, one line per element, is trivial:
open my $handle, '<', $path_to_file;
chomp(my @lines = <$handle>);
close $handle;
Now the lines of the file are in the array @lines
.
If you want to make sure there is error handling for open
and close
, do something like this (in the snipped below, we open the file in UTF-8 mode, too):
my $handle;
unless (open $handle, "<:encoding(utf8)", $path_to_file) {
print STDERR "Could not open file '$path_to_file': $!\n";
# we return 'undefined', we could also 'die' or 'croak'
return undef
}
chomp(my @lines = <$handle>);
unless (close $handle) {
# what does it mean if close yields an error and you are just reading?
print STDERR "Don't care error while closing '$path_to_file': $!\n";
}
I faced the same issue and successfully solved it. My use-case is this.
"Post JSON data to the server and receive an excel file. That excel file is created by the server and returned as a response to the client. Download that response as a file with custom name in browser"
$("#my-button").on("click", function(){
// Data to post
data = {
ids: [1, 2, 3, 4, 5]
};
// Use XMLHttpRequest instead of Jquery $ajax
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
var a;
if (xhttp.readyState === 4 && xhttp.status === 200) {
// Trick for making downloadable link
a = document.createElement('a');
a.href = window.URL.createObjectURL(xhttp.response);
// Give filename you wish to download
a.download = "test-file.xls";
a.style.display = 'none';
document.body.appendChild(a);
a.click();
}
};
// Post data to URL which handles post request
xhttp.open("POST", excelDownloadUrl);
xhttp.setRequestHeader("Content-Type", "application/json");
// You should set responseType as blob for binary responses
xhttp.responseType = 'blob';
xhttp.send(JSON.stringify(data));
});
The above snippet is just doing following
Here we need to carefully set few things at the server side. I set few headers in Python Django HttpResponse. You need to set them accordingly if you use other programming languages.
# In python django code
response = HttpResponse(file_content, content_type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
Since I download xls(excel) here, I adjusted contentType to above one. You need to set it according to your file type. You can use this technique to download any kind of files.
The onclick
attribute on your anchor tag is going to call a client-side function. (This is what you would use if you wanted to call a javascript function when the link is clicked.)
What you want is a server-side control, like the LinkButton
:
<asp:LinkButton ID="lnkTutorial" runat="server" Text="Tutorial" OnClick="displayTutorial_Click"/>
This has an OnClick
attribute that will call the method in your code behind.
Looking further into your code, it looks like you're just trying to open a different tutorial based on access level of the user. You don't need an event handler for this at all. A far better approach would be to just set the end point of your LinkButton
control in the code behind.
protected void Page_Load(object sender, EventArgs e)
{
userinfo = (UserInfo)Session["UserInfo"];
if (userinfo.user == "Admin")
{
lnkTutorial.PostBackUrl = "help/AdminTutorial.html";
}
else
{
lnkTutorial.PostBackUrl = "help/UserTutorial.html";
}
}
Really, it would be best to check that you actually have a user first.
protected void Page_Load(object sender, EventArgs e)
{
if (Session["UserInfo"] != null && ((UserInfo)Session["UserInfo"]).user == "Admin")
{
lnkTutorial.PostBackUrl = "help/AdminTutorial.html";
}
else
{
lnkTutorial.PostBackUrl = "help/UserTutorial.html";
}
}
I've found the same thing, but only on emulators that have the Use Host GPU setting ticked. Try turning that off, you'll no longer see those warnings (and the emulator will run horribly, horribly slowly..)
In my experience those warnings are harmless. Notice that the "error" is EGL_SUCCESS, which would seem to indicate no error at all!
It is very easy to remember. In hexadecimal one digit is 4 bits. So for unsigned int write 0x
and 8 f
s (0xffffffff
) into a Python or Ruby shell to get the value in base 10. If you need the signed value, just remember that the highest bit is used as the sign. So you have to leave that out. You only need to remember that the number where the lower 3 bits are 1 and the 4th bit is 0 equals 7, so write 0x7fffffff
into a Python or Ruby shell. You could also write 0x100000000 - 1
and 0x80000000 - 1
, if that is more easy to you to remember.
From the definition of height:
Applies to: all elements but non-replaced inline elements, table columns, and column groups
An a
element is, by default an inline element (and it is non-replaced).
You need to change the display (directly with the display property or indirectly, e.g. with float).
In my case (using XCode 10.0) nothing worked but this:
File > Project Settings... > Shared Project Settings: > Build System --> Selected "Legacy Build System" instead of the default "New Build System (Default)".
I posted my answer even though another answer has already been accepted; the accepted answer relies on a deprecated function; additionally, this deprecated function is based on Singular Value Decomposition (SVD), which (although perfectly valid) is the much more memory- and processor-intensive of the two general techniques for calculating PCA. This is particularly relevant here because of the size of the data array in the OP. Using covariance-based PCA, the array used in the computation flow is just 144 x 144, rather than 26424 x 144 (the dimensions of the original data array).
Here's a simple working implementation of PCA using the linalg module from SciPy. Because this implementation first calculates the covariance matrix, and then performs all subsequent calculations on this array, it uses far less memory than SVD-based PCA.
(the linalg module in NumPy can also be used with no change in the code below aside from the import statement, which would be from numpy import linalg as LA.)
The two key steps in this PCA implementation are:
calculating the covariance matrix; and
taking the eivenvectors & eigenvalues of this cov matrix
In the function below, the parameter dims_rescaled_data refers to the desired number of dimensions in the rescaled data matrix; this parameter has a default value of just two dimensions, but the code below isn't limited to two but it could be any value less than the column number of the original data array.
def PCA(data, dims_rescaled_data=2):
"""
returns: data transformed in 2 dims/columns + regenerated original data
pass in: data as 2D NumPy array
"""
import numpy as NP
from scipy import linalg as LA
m, n = data.shape
# mean center the data
data -= data.mean(axis=0)
# calculate the covariance matrix
R = NP.cov(data, rowvar=False)
# calculate eigenvectors & eigenvalues of the covariance matrix
# use 'eigh' rather than 'eig' since R is symmetric,
# the performance gain is substantial
evals, evecs = LA.eigh(R)
# sort eigenvalue in decreasing order
idx = NP.argsort(evals)[::-1]
evecs = evecs[:,idx]
# sort eigenvectors according to same index
evals = evals[idx]
# select the first n eigenvectors (n is desired dimension
# of rescaled data array, or dims_rescaled_data)
evecs = evecs[:, :dims_rescaled_data]
# carry out the transformation on the data using eigenvectors
# and return the re-scaled data, eigenvalues, and eigenvectors
return NP.dot(evecs.T, data.T).T, evals, evecs
def test_PCA(data, dims_rescaled_data=2):
'''
test by attempting to recover original data array from
the eigenvectors of its covariance matrix & comparing that
'recovered' array with the original data
'''
_ , _ , eigenvectors = PCA(data, dim_rescaled_data=2)
data_recovered = NP.dot(eigenvectors, m).T
data_recovered += data_recovered.mean(axis=0)
assert NP.allclose(data, data_recovered)
def plot_pca(data):
from matplotlib import pyplot as MPL
clr1 = '#2026B2'
fig = MPL.figure()
ax1 = fig.add_subplot(111)
data_resc, data_orig = PCA(data)
ax1.plot(data_resc[:, 0], data_resc[:, 1], '.', mfc=clr1, mec=clr1)
MPL.show()
>>> # iris, probably the most widely used reference data set in ML
>>> df = "~/iris.csv"
>>> data = NP.loadtxt(df, delimiter=',')
>>> # remove class labels
>>> data = data[:,:-1]
>>> plot_pca(data)
The plot below is a visual representation of this PCA function on the iris data. As you can see, a 2D transformation cleanly separates class I from class II and class III (but not class II from class III, which in fact requires another dimension).
The best explanation is the GNU make manual itself: 4.6 Phony Targets section.
.PHONY
is one of make's Special Built-in Target Names. There are other targets that you may be interested in, so it's worth skimming through these references.
When it is time to consider a .PHONY target, make will run its recipe unconditionally, regardless of whether a file with that name exists or what its last-modification time is.
You may also be interested in make's Standard Targets such as all

Put this in your MainActivity:
{
public EditText bizname, storeno, rcpt, item, price, tax, total;
public Button click, click2;
int contentView;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( R.layout.main_activity );
bizname = (EditText) findViewById( R.id.editBizName );
item = (EditText) findViewById( R.id.editItem );
price = (EditText) findViewById( R.id.editPrice );
tax = (EditText) findViewById( R.id.editTax );
total = (EditText) findViewById( R.id.editTotal );
click = (Button) findViewById( R.id.button );
}
}
Put this under a button or something
public void clickBusiness(View view) {
checkPermsOfStorage( this );
bizname = (EditText) findViewById( R.id.editBizName );
item = (EditText) findViewById( R.id.editItem );
price = (EditText) findViewById( R.id.editPrice );
tax = (EditText) findViewById( R.id.editTax );
total = (EditText) findViewById( R.id.editTotal );
String x = ("\nItem/Price: " + item.getText() + price.getText() + "\nTax/Total" + tax.getText() + total.getText());
Toast.makeText( this, x, Toast.LENGTH_SHORT ).show();
try {
this.WriteBusiness(bizname,storeno,rcpt,item,price,tax,total);
String vv = tax.getText().toString();
System.console().printf( "%s", vv );
//new XMLDivisionWriter(getString(R.string.SDDoc) + "/tax_div_business.xml");
} catch (ReflectiveOperationException e) {
e.printStackTrace();
}
}
There! The debate is settled!
Today, you should be representing a folder using its content: URI as obtained from the Storage Access Framework, and opening it should be as simple as:
Intent i = new Intent(Intent.ACTION_VIEW, uri);
startActivity(i);
Alas, the Files app currently contains a bug that causes it to crash when you try this using the external storage provider. Folders from third party providers however can be displayed in this way.
You must use the equals operator not the assignment like
if(document.form1.radio1[0].checked == true) {
alert("You have selected Option 1");
}
it seems you can directly call:
g = sns.factorplot("class", "survived", "sex",
data=titanic, kind="bar",
size=6, palette="muted",
legend_out=False)
g._legend.set_bbox_to_anchor((.7, 1.1))
Alternatively, If you are too lazy to write the SQL query. Then this solution is for you.
I suggest
l = re.compile("(?<!^)\s+(?=[A-Z])(?!.\s)").split(s)
Check this demo.
In Python 2.7, the new way of removing duplicates from an iterable while keeping it in the original order is:
>>> from collections import OrderedDict
>>> list(OrderedDict.fromkeys('abracadabra'))
['a', 'b', 'r', 'c', 'd']
In Python 3.5, the OrderedDict has a C implementation. My timings show that this is now both the fastest and shortest of the various approaches for Python 3.5.
In Python 3.6, the regular dict became both ordered and compact. (This feature is holds for CPython and PyPy but may not present in other implementations). That gives us a new fastest way of deduping while retaining order:
>>> list(dict.fromkeys('abracadabra'))
['a', 'b', 'r', 'c', 'd']
In Python 3.7, the regular dict is guaranteed to both ordered across all implementations. So, the shortest and fastest solution is:
>>> list(dict.fromkeys('abracadabra'))
['a', 'b', 'r', 'c', 'd']

Avoid appending strings using String + String etc, use StringBuilder instead.
String separator = System.getProperty( "line.separator" );
StringBuilder lines = new StringBuilder( line1 );
lines.append( separator );
lines.append( line2 );
lines.append( separator );
String result = lines.toString( );
Number (2) is possible by using a socket implementation (like websocket, socket.io, etc.) with a custom heartbeat for each session the user is engaged in. If a user attempts to open another window, you have a javascript handler check with the server if it's ok, and then respond with an error messages.
However, a better solution is to synchronize the two sessions if possible like in google docs.
To delete a tag on your remote repository, you can use
git push <remote> :refs/tags/<tagname>
The way to interpret the above is to read it as the null value, the value before the colon is being pushed to remote tag name.
It can depend, especially on whether your file will have the same number of items on each row or not. If it will, then you probably want a 2D matrix class of some sort, usually something like this:
class array2D {
std::vector<double> data;
size_t columns;
public:
array2D(size_t x, size_t y) : columns(x), data(x*y) {}
double &operator(size_t x, size_t y) {
return data[y*columns+x];
}
};
Note that as it's written, this assumes you know the size you'll need up-front. That can be avoided, but the code gets a little larger and more complex.
In any case, to read the numbers and maintain the original structure, you'd typically read a line at a time into a string, then use a stringstream to read numbers from the line. This lets you store the data from each line into a separate row in your array.
If you don't know the size ahead of time or (especially) if different rows might not all contain the same number of numbers:
11 12 13
23 34 56 78
You might want to use a std::vector<std::vector<double> >
instead. This does impose some overhead, but if different rows may have different sizes, it's an easy way to do the job.
std::vector<std::vector<double> > numbers;
std::string temp;
while (std::getline(infile, temp)) {
std::istringstream buffer(temp);
std::vector<double> line((std::istream_iterator<double>(buffer)),
std::istream_iterator<double>());
numbers.push_back(line);
}
...or, with a modern (C++11) compiler, you can use brackets for line
's initialization:
std::vector<double> line{std::istream_iterator<double>(buffer),
std::istream_iterator<double>()};
There is now a beta available of Google Maps KML Importing Utility.

KmlLayer layer = new KmlLayer(getMap(), R.raw.kmlFile, getApplicationContext());
After you have created a KmlLayer, call addLayerToMap() to add the imported data onto the map.
layer.addLayerToMap();

I really struggled with getting the results of jQuery ajax into my variables at the "document.ready" stage of events.
jQuery's ajax would load into my variables when a user triggered an "onchange" event of a select box after the page had already loaded, but the data would not feed the variables when the page first loaded.
I tried many, many, many different methods, but in the end, it was Charles Guilbert's method that worked best for me.
Hats off to Charles Guilbert! Using his answer, I am able to get data into my variables, even when my page first loads.
Here's an example of the working script:
jQuery.extend
(
{
getValues: function(url)
{
var result = null;
$.ajax(
{
url: url,
type: 'get',
dataType: 'html',
async: false,
cache: false,
success: function(data)
{
result = data;
}
}
);
return result;
}
}
);
// Option List 1, when "Cats" is selected elsewhere
optList1_Cats += $.getValues("/MyData.aspx?iListNum=1&sVal=cats");
// Option List 1, when "Dogs" is selected elsewhere
optList1_Dogs += $.getValues("/MyData.aspx?iListNum=1&sVal=dogs");
// Option List 2, when "Cats" is selected elsewhere
optList2_Cats += $.getValues("/MyData.aspx?iListNum=2&sVal=cats");
// Option List 2, when "Dogs" is selected elsewhere
optList2_Dogs += $.getValues("/MyData.aspx?iListNum=2&sVal=dogs");
Use FileUtils with FileUtils.deleteDirectory();
The differences in practice :
string testString = "";
Console.WriteLine(string.Format("IsNullOrEmpty : {0}", string.IsNullOrEmpty(testString)));
Console.WriteLine(string.Format("IsNullOrWhiteSpace : {0}", string.IsNullOrWhiteSpace(testString)));
Console.ReadKey();
Result :
IsNullOrEmpty : True
IsNullOrWhiteSpace : True
**************************************************************
string testString = " MDS ";
IsNullOrEmpty : False
IsNullOrWhiteSpace : False
**************************************************************
string testString = " ";
IsNullOrEmpty : False
IsNullOrWhiteSpace : True
**************************************************************
string testString = string.Empty;
IsNullOrEmpty : True
IsNullOrWhiteSpace : True
**************************************************************
string testString = null;
IsNullOrEmpty : True
IsNullOrWhiteSpace : True
You have to use the String method .toLowerCase()
or .toUpperCase()
on both the input and the string you are trying to match it with.
Example:
public static void findPatient() {
System.out.print("Enter part of the patient name: ");
String name = sc.nextLine();
System.out.print(myPatientList.showPatients(name));
}
//the other class
ArrayList<String> patientList;
public void showPatients(String name) {
boolean match = false;
for(String matchingname : patientList) {
if (matchingname.toLowerCase().contains(name.toLowerCase())) {
match = true;
}
}
}
404 is just the HTTP response code. On top of that, you can provide a response body and/or other headers with a more meaningful error message that developers will see.

In addition to Trufa's comment, Unicode explicitly isn't UTF-16. When they were first looking into Unicode, it was speculated that a 16-bit integer might be enough to store any code, but in practice that turned out not to be the case. However, UTF-16 is another valid encoding of Unicode - alongside the 8-bit and 32-bit variants - and I believe is the encoding that Microsoft use in memory at runtime on the NT-derived operating systems.
Datetime is a datatype.
Timestamp is a method for row versioning. In fact, in sql server 2008 this column type was renamed (i.e. timestamp is deprecated) to rowversion. It basically means that every time a row is changed, this value is increased. This is done with a database counter which automatically increase for every inserted or updated row.

Generally you shouldn't rely on system properties to configure a webapp - they may be used to configure the container (e.g. Tomcat) but not an application running inside tomcat.
cliff.meyers has already mentioned the way you should rather use for your webapplication. That's the standard way, that also fits your question of being configurable through context.xml or server.xml means.
That said, should you really need system properties or other jvm options (like max memory settings) in tomcat, you should create a file named "bin/setenv.sh" or "bin/setenv.bat". These files do not exist in the standard archive that you download, but if they are present, the content is executed during startup (if you start tomcat via startup.sh/startup.bat). This is a nice way to separate your own settings from the standard tomcat settings and makes updates so much easier. No need to tweak startup.sh or catalina.sh.
(If you execute tomcat as windows servive, you usually use tomcat5w.exe, tomcat6w.exe etc. to configure the registry settings for the service.)
EDIT: Also, another possibility is to go for JNDI Resources.

I used the workaround that r3bel posted: Can you use CSS3 to transition from height:0 to the variable height of content?
What is returned is milliseconds since epoch. You could do:
var d = new Date();
d.setTime(1245398693390);
document.write(d);
On how to format the date exactly as you want, see full Date
reference at http://www.w3schools.com/jsref/jsref_obj_date.asp
You could strip the non-digits by either parsing the integer (as suggested here):
var date = new Date(parseInt(jsonDate.substr(6)));
Or applying the following regular expression (from Tominator in the comments):
var jsonDate = jqueryCall(); // returns "/Date(1245398693390)/";
var re = /-?\d+/;
var m = re.exec(jsonDate);
var d = new Date(parseInt(m[0]));
ALTER TABLE {TABLE NAME}
ALTER COLUMN {COLUMN NAME} SET DEFAULT '{DEFAULT VALUES}'
example :
ALTER TABLE RESULT
ALTER COLUMN STATUS SET DEFAULT 'FAIL'
Here is the code
String str = "Hi There";
char[] arr = str.toCharArray();
for(int i=0;i<arr.length;i++)
System.out.print(" "+arr[i]);

You can delete all related photos before actually deleting the user.
<?php
class User extends Eloquent
{
public function photos()
{
return $this->has_many('Photo');
}
public function delete()
{
// delete all related photos
$this->photos()->delete();
// as suggested by Dirk in comment,
// it's an uglier alternative, but faster
// Photo::where("user_id", $this->id)->delete()
// delete the user
return parent::delete();
}
}
Hope it helps.

The just call cls() anywhere
I had the same issue.
During the 1st development I used a .csv file (comma as separator) that I've modified a bit before saving it. After saving the commas became semicolon.
On Windows it is dependent on the "Regional and Language Options" customize screen where you find a List separator. This is the char Windows applications expect to be the CSV separator.
When testing from a brand new file I encountered that issue.
I've removed the 'sep' argument in read_csv method before:
df1 = pd.read_csv('myfile.csv', sep=',');
after:
df1 = pd.read_csv('myfile.csv');
That way, the issue disappeared.
Sometimes is worth to remove new line characters \n
like:
conn.exec <<-eos.squish

from table1, table2, table3, etc, etc, etc, etc, etc,

Many unix
-like systems (Linux
, the BSD
s, and OS X
, at the very least) have the fts
functions for directory traversal.
To recursively delete a directory, perform a depth-first traversal (without following symlinks) and remove every visited file:
int recursive_delete(const char *dir)
{
int ret = 0;
FTS *ftsp = NULL;
FTSENT *curr;
// Cast needed (in C) because fts_open() takes a "char * const *", instead
// of a "const char * const *", which is only allowed in C++. fts_open()
// does not modify the argument.
char *files[] = { (char *) dir, NULL };
// FTS_NOCHDIR - Avoid changing cwd, which could cause unexpected behavior
// in multithreaded programs
// FTS_PHYSICAL - Don't follow symlinks. Prevents deletion of files outside
// of the specified directory
// FTS_XDEV - Don't cross filesystem boundaries
ftsp = fts_open(files, FTS_NOCHDIR | FTS_PHYSICAL | FTS_XDEV, NULL);
if (!ftsp) {
fprintf(stderr, "%s: fts_open failed: %s\n", dir, strerror(errno));
ret = -1;
goto finish;
}
while ((curr = fts_read(ftsp))) {
switch (curr->fts_info) {
case FTS_NS:
case FTS_DNR:
case FTS_ERR:
fprintf(stderr, "%s: fts_read error: %s\n",
curr->fts_accpath, strerror(curr->fts_errno));
break;
case FTS_DC:
case FTS_DOT:
case FTS_NSOK:
// Not reached unless FTS_LOGICAL, FTS_SEEDOT, or FTS_NOSTAT were
// passed to fts_open()
break;
case FTS_D:
// Do nothing. Need depth-first search, so directories are deleted
// in FTS_DP
break;

Generally speak I defined null
as it indicates a human set the value and undefined
to indicate no setting has taken place.
I guess I found a simpler solution
temp1 = pd.melt(df1, id_vars=["location"], var_name='Date', value_name='Value')
temp2 = pd.melt(df1, id_vars=["name"], var_name='Date', value_name='Value')
Concat whole temp1
with temp2
's column name
temp1['new_column'] = temp2['name']
You now have what you asked for.
Try:
.Formula = "='" & strProjectName & "'!" & Cells(2, 7).Address
If your worksheet name (strProjectName
) has spaces, you need to include the single quotes in the formula string.
If this does not resolve it, please provide more information about the specific error or failure.
Update
In comments you indicate you're replacing spaces with underscores. Perhaps you are doing something like:
strProjectName = Replace(strProjectName," ", "_")
But if you're not also pushing that change to the Worksheet.Name
property, you can expect these to happen:
#REF
errorThe reason for both is that you are passing a reference to a worksheet that doesn't exist, which is why you get the #REF error. The file dialog is an attempt to let you correct that reference, by pointing to a file wherein that sheet name does exist. When you cancel out, the #REF error is expected.
So you need to do:
Worksheets(strProjectName).Name = Replace(strProjectName," ", "_")
strProjectName = Replace(strProjectName," ", "_")
Then, your formula should work.
df.filter(regex='[A-CEG-I]') # does NOT depend on the column order
Note that any regular expression is allowed here, so this approach can be very general. E.g. if you wanted all columns starting with a capital or lowercase "A" you could use: df.filter(regex='^[Aa]')
df[ list(df.loc[:,'A':'C']) + ['E'] + list(df.loc[:,'G':'I']) ]
Note that unlike the label-based method, this only works if your columns are alphabetically sorted. This is not necessarily a problem, however. For example, if your columns go ['A','C','B']
, then you could replace 'A':'C'
above with 'A':'B'
.
And for completeness, you always have the option shown by @Magdalena of simply listing each column individually, although it could be much more verbose as the number of columns increases:
df[['A','B','C','E','G','H','I']] # does NOT depend on the column order
A B C E G H I
0 -0.814688 -1.060864 -0.008088 2.697203 -0.763874 1.793213 -0.019520
1 0.549824 0.269340 0.405570 -0.406695 -0.536304 -1.231051 0.058018
2 0.879230 -0.666814 1.305835 0.167621 -1.100355 0.391133 0.317467
In Python 2 you can avoid making a temporary copy of all the values by using the itervalues()
dictionary method, which returns an iterator of the dictionary's keys:
sum(d.itervalues())
In Python 3 you can just use d.values()
because that method was changed to do that (and itervalues()
was removed since it was no longer needed).
To make it easier to write version independent code which always iterates over the values of the dictionary's keys, a utility function can be helpful:
import sys
def itervalues(d):
return iter(getattr(d, ('itervalues', 'values')[sys.version_info[0]>2])())
sum(itervalues(d))
This is essentially what Benjamin Peterson's six
module does.
Cross browser window.load event
function load(){}
window[ addEventListener ? 'addEventListener' : 'attachEvent' ]( addEventListener ? 'load' : 'onload', load )
Update: You can now <Elem onClick={ proxy => proxy.stopPropagation() } />
FWIW CloudFront supports streaming as well. Might be better than plain streaming from instances.
You should use the OpenFileDialog class like this
Dim fd As OpenFileDialog = New OpenFileDialog()
Dim strFileName As String
fd.Title = "Open File Dialog"
fd.InitialDirectory = "C:\"
fd.Filter = "All files (*.*)|*.*|All files (*.*)|*.*"
fd.FilterIndex = 2
fd.RestoreDirectory = True
If fd.ShowDialog() = DialogResult.OK Then
strFileName = fd.FileName
End If
Then you can use the File class.
You're apparently off by one day, exactly 86400 seconds. Use the number 2209161600 Not the number 2209075200 If you Google the two numbers, you'll find support for the above. I tried your formula but was always coming up 1 day different from my server. It's not obvious from the unix timestamp unless you think in unix instead of human time ;-) but if you double check then you'll see this might be correct.

From the documentation Restore activity UI state using saved instance state it is stated as:
Instead of restoring the state during onCreate() you may choose to implement onRestoreInstanceState(), which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null:
IMO, this is more clear way than checking this at onCreate, and better fits with single responsiblity principle.
This is caused by the regional settings of your computer.
When you paste data into excel it is only a bunch of strings (not dates).
Excel has some logic in it to recognize your current data formats as well as a few similar date formats or obvious date formats where it can assume it is a date. When it is able to match your pasted in data to a valid date then it will format it as a date in the cell it is in.
Your specific example is due to your list of dates is formatted as "m/d/yy" which is US format. it pastes correctly in my excel because I have my regional setting set to "US English" (even though I'm Canadian :) )
If you system is set to Canadian English/French format then it will expect "d/m/yy" format and not recognize any date where the month is > 13.
The best way to import data, that contains dates, into excel is to copy it in this format.
2011-04-22

2011-04-01
Which is "yyyy-MM-dd", this format is recognized the same way on every computer I have ever seen (is often refered to as ODBC format or Standard format) where the units are always from greatest to least weight ("yyyy-MM-dd HH:mm:ss.fff") another side effect is it will sort correctly as a string.
To avoid swaping your regional settings back and forth you may consider writting a macro in excel to paste the data in. a simple popup format and some basic logic to reformat the dates would not be too difficult.
I know this is not a coding answer but it is what the OP wanted and what I have spent half the day trying to achieve - print from a web page with page numbers.
Yes, it is two steps instead of one but I haven't been able to find any CSS option despite several hours of searching. Real shame all the browsers removed the functionality that used to allow it.
If you are using the fixed pipeline (OpenGL < 3.3) or the compatibility profile you can use
//Turn on wireframe mode
glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);
//Draw the scene with polygons as lines (wireframe)
renderScene();
//Turn off wireframe mode
glPolygonMode(GL_FRONT_AND_BACK, GL_FILL);
In this case you can change the line width by calling glLineWidth
Otherwise you need to change the polygon mode inside your draw method (glDrawElements, glDrawArrays, etc) and you may end up with some rough results because your vertex data is for triangles and you are outputting lines. For best results consider using a Geometry shader or creating new data for the wireframe.
Most probably the file is just being cached by the server. You could either disable cache (but remember to enable it when the site goes live), or modify href
of your link
tag, so the server will not load it from cache.
If your page is created dynamically by some language like php, you could add some variable at the end of the href
value, like:
<link rel="stylesheet" type="text/css" href="css/yourStyles.css?<?php echo time(); ?>" />
That will add the current timestamp on the end of a file path, so it will always be unique and never loaded from cache.
If your page is static, you have to manage those variables yourself, so use something like:
<link rel="stylesheet" type="text/css" href="css/yourStyles.css?version=1" />
after doing some changes in the file content, change version=1
to version=2
and so on.
If you wish to disable the cache from caching css files, refer to your server type documentation (it's done differently on apache, IIS, nginx etc.) or ask/search for a question on https://serverfault.com/
Assuming IIS - adding the key under with the right settings in the root or the relevant folder does the trick.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<caching enabled="false" enableKernelCache="false" /> <!-- This one -->
</system.webServer>
</configuration>
That said sometimes one still has to recycle the Application Pool to "bump" the CSS. Therefore: Disabling IIS caching alone is not a 100% guaranteed solution.
For the browser: There are some notes on fine-grain controlling the local cache on FF over on SuperUser for the interested.
Adding/changing style of the elements in code is a bad practice. Today you want to change the background color and tomorrow you would like to change background image and after tomorrow you decided that it would be also nice to change the border.
Editing the code every-time only because the design requirements changes is a pain. Also, if your project will grow, changing js files will be even more pain. More code, more pain.
Try to eliminate use of hard coded styles, this will save you time and, if you do it right, you could ask to do the "change-color" task to someone else.
So, instead of changing direct properties of style, you can add/remove CSS classes on nodes. In your specific case, you only need to do this for parent node - "div" and then, style the subnodes through CSS. So no need to apply specific style property to DIV and to H2.
One more recommendation point. Try not to connect nodes hardcoded, but use some semantic to do that. For example: "To add events to all nodes which have class 'content'.
In conclusion, here is the code which I would use for such tasks:
//for adding a css class
function onOver(node){
node.className = node.className + ' Hover';
}
//for removing a css class
function onOut(node){
node.className = node.className.replace('Hover','');
}
function connect(node,event,fnc){
if(node.addEventListener){
node.addEventListener(event.substring(2,event.length),function(){
fnc(node);
},false);
}else if(node.attachEvent){
node.attachEvent(event,function(){
fnc(node);
});
}
}
// run this one when window is loaded
var divs = document.getElementsByTagName("div");
for(var i=0,div;div =divs[i];i++){
if(div.className.match('content')){
connect(div,'onmouseover',onOver);
connect(div,'onmouseout',onOut);
}
}
And you CSS whould be like this:
.content {
background-color: blue;
}
.content.Hover{
background-color: red;
}
.content.Hover h2{
background-color : yellow;
}
I know this is a really old post, but I found it in searching for a solution to the same problem. I don't want a nested if-statement, and Switch is apparently newer than the version of Excel I'm using. I figured out what was going wrong with my code, so I figured I'd share here in case it helps someone else.
I remembered that VLOOKUP requires the source table to be sorted alphabetically/numerically for it to work. I was initially trying to do this...
=LOOKUP(LOWER(LEFT($T$3, 1)), {"s","l","m"}, {-1,1,0})
and it started working when I did this...
=LOOKUP(LOWER(LEFT($T$3, 1)), {"l","m","s"}, {1,0,-1})
I was initially thinking the last value might turn out to be a default, so I wanted the zero at the last place. That doesn't seem to be the behavior anyway, so I just put the possible matches in order, and it worked.
Edit: As a final note, I see that the example in the original post has letters in alphabetical order, but I imagine the real use case might have been different if the error was happening and the letters A, B, and C were just examples.
Dojo does, e.g. via JsonRestStore, see http://www.sitepen.com/blog/2008/06/13/restful-json-dojo-data/ .
LIFO is the way browser parses CSS properties..If you are using Sass declare a variable called as
"$header-background: red;"
use it instead of directly assigning values like red or blue. When you want to override just reassign the value to
"$header-background:blue"
then
background-color:$header-background;
it should smoothly override. Using "!important" is not always the right choice..Its just a hotfix
In Vue2 be aware that you can access this.$refs.uniqueName only after mounting the component.
To be absolutely correct you should put all the names into the SAN field.
The CN field should contain a Subject Name not a domain name, but when the Netscape found out this SSL thing, they missed to define its greatest market. Simply there was not certificate field defined for the Server URL.
This was solved to put the domain into the CN field, and nowadays usage of the CN field is deprecated, but still widely used. The CN can hold only one domain name.
The general rules for this: CN - put here your main URL (for compatibility) SAN - put all your domain here, repeat the CN because its not in right place there, but its used for that...
If you found a correct implementation, the answers for your questions will be the followings:
Has this setup a special meaning, or any [dis]advantages over setting both CNs? You cant set both CNs, because CN can hold only one name. You can make with 2 simple CN certificate instead one CN+SAN certificate, but you need 2 IP addresses for this.
What happens on server-side if the other one, host.domain.tld, is being requested? It doesn't matter whats happen on server side.
In short: When a browser client connects to this server, then the browser sends encrypted packages, which are encrypted with the public key of the server. Server decrypts the package, and if server can decrypt, then it was encrypted for the server.
The server doesn't know anything from the client before decrypt, because only the IP address is not encrypted trough the connection. This is why you need 2 IPs for 2 certificates. (Forget SNI, there is too much XP out there still now.)
On client side the browser gets the CN, then the SAN until all of the are checked. If one of the names matches for the site, then the URL verification was done by the browser. (im not talking on the certificate verification, of course a lot of ocsp, crl, aia request and answers travels on the net every time.)
Usually in such cases, it is coming in scope of more meaningful logic, let's say some searching or manipulating over some of the iterated 'for'-objects in question, so I usually use the functional approach:
public Object searching(Object[] types) { // Or manipulating
List<Object> typesReferences = new ArrayList<Object>();
List<Object> typesReferences2 = new ArrayList<Object>();
for (Object type : typesReferences) {
Object o = getByCriterion(typesReferences2, type);
if(o != null) return o;
}
return null;
}
private Object getByCriterion(List<Object> typesReferences2, Object criterion) {
for (Object typeReference : typesReferences2) {
if(typeReference.equals(criterion)) {
// here comes other complex or specific logic || typeReference.equals(new Object())
return typeReference;
}
}
return null;
}
Major cons:
The pros:
So it is just handling the case via a different approach.
Basically a question to the author of this question: what do you consider of this approach?
For performance reasons, don't draw a circle if you can avoid it. Just draw a rectangle with a width and height of one:
ctx.fillRect(10,10,1,1); // fill in the pixel at (10,10)
date -j -f "%Y-%m-%d %H:%M:%S" "2020-04-07 00:00:00" "+%s"
It will print the dynamic seconds when without %H:%M:%S
and 00:00:00
.
If you need a serializable, immutable list with a single entity you can use:
List<String> singList = Collections.singletonList("stackoverlow");

What is wrong here is that your session management configuration is set to close session when you commit transaction. Check if you have something like:
<property name="current_session_context_class">thread</property>
in your configuration.
In order to overcome this problem you could change the configuration of session factory or open another session and only than ask for those lazy loaded objects. But what I would suggest here is to initialize this lazy collection in getModelByModelGroup itself and call:
Hibernate.initialize(subProcessModel.getElement());
when you are still in active session.
And one last thing. A friendly advice. You have something like this in your method:
for (Model m : modelList) {
if (m.getModelType().getId() == 3) {
model = m;
break;
}
}
Please insted of this code just filter those models with type id equal to 3 in the query statement just couple of lines above.

There are mainly two ways to use JDBC - using Windows authentication and SQL authentication. SQL authentication is probably the easiest. What you can do is something like:
String userName = "username";
String password = "password";
String url = "jdbc:sqlserver://MYPC\\SQLEXPRESS;databaseName=MYDB";
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url, userName, password);
after adding sqljdbc4.jar to the build path.
For Window authentication you can do something like:
String url = "jdbc:sqlserver://MYPC\\SQLEXPRESS;databaseName=MYDB;integratedSecurity=true";
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url);
and then add the path to sqljdbc_auth.dll as a VM argument (still need sqljdbc4.jar in the build path).
Please take a look here for a short step-by-step guide showing how to connect to SQL Server from Java using jTDS and JDBC should you need more details. Hope it helps!
I felt the below approach is very easy.
I have declared an interface for callback
public interface AsyncResponse {
void processFinish(Object output);
}
Then created asynchronous Task for responding all type of parallel requests
public class MyAsyncTask extends AsyncTask<Object, Object, Object> {
public AsyncResponse delegate = null;//Call back interface
public MyAsyncTask(AsyncResponse asyncResponse) {
delegate = asyncResponse;//Assigning call back interfacethrough constructor
}
@Override
protected Object doInBackground(Object... params) {
//My Background tasks are written here
return {resutl Object}
}
@Override
protected void onPostExecute(Object result) {
delegate.processFinish(result);
}
}
Then Called the asynchronous task when clicking a button in activity Class.
public class MainActivity extends Activity {

Are you sure, that specified database and table exists? Did you try to look at your database using any database client? For example command-line MySQL client bundled with MySQL server. Or if you a developer newbie, there are dozens of a GUI and web interface clients (HeidiSQL, MySQL Workbench, phpMyAdmin and many more). So first check, if your table creation script was successful and had created what it have to.
BTW why do you have a script for creating the database structure? It's usualy a nonrecurring operation, so write the script to do this is unneeded. It's useful only in case of need of repeatedly creating and manipulating the database structure on the fly.
SELECT * FROM Table_Name LIMIT 5;
To search the whole computer:
gdr -PSProvider 'FileSystem' | %{ ls -r $.root} 2>$null | where { $.name -eq "httpd.exe" }
I am pretty sure this is a much less efficient command, for MANY reasons, but the simplest is your piping everything to your where-object command, when you could still use -filter "httpd.exe" and save a ton of cycles.
Also, on a lot of computers the get-psdrive is gonna grab shared drives, and I am pretty sure you wanted that to get a complete search. Most shares can be IMMENSE with regard to the sheer number of files and folders, so at the very least I would sort my drives by size, and add a check after each search to exit the loop if we locate the file. That is if you are looking for a single instance, if not the only way to save yourself the IMMENSE time sink of searching a 10TB share or two, is to comment the command and highly suggest any user who were to need to use it should limit their search as much as they can. For instance our User Profile share is 10TB, at least the one I am on is, and I can limit my search to the directory $sharedrive\users\myname and search my 116GB directory rather than the 10TB one. Too many unknowns with shares for this type of script, which is already super inefficient with regard to resources and speed.
If I was seriously considering using something like this, I would add a call to a 3rd party package and leverage a DB.
NetBeans IDE users can do it as below:
Select the project
right click Subversion Export
In the dialog box
export to folder /var/tmp/projectname press export wait will show complete will ask do you want to open it do open on the fly
You can now switch to Git :)
To enable zoom controls in a WebView, add the following line:
webView.getSettings().setBuiltInZoomControls(true);
With this line of code, you get the zoom enabled in your WebView, if you want to remove the zoom in and zoom out buttons provided, add the following line of code:
webView.getSettings().setDisplayZoomControls(false);
I found that if the application within the httpd server has a rule like "if the X-Frame-Options header exists and has a value, leave it alone; otherwise add the header X-Frame-Options: SAMEORIGIN" then an httpd.conf mod_headers rule like "Header always unset X-Frame-Options" would not suffice. The SAMEORIGIN value would always reach the client.
To remedy this, I add two, not one, mod_headers rules (in the outermost httpd.conf file):
Header set X-Frame-Options ALLOW-FROM http://to.be.deleted.com early
Header unset X-Frame-Options
The first rule tells any internal request handler that some other agent has taken responsibility for clickjack prevention and it can skip its attempt to save the world. It runs with "early" processing. The second rule strips off the entirely unwanted X-Frame-Options header. It runs with "late" processing.
I also add the appropriate Content-Security-Policy headers so that the world remains protected yet multi-sourced Javascript from trusted sites still gets to run.
use an iframe and hide it iframe works like a body tag
<!DOCTYPE html>
<html>
<body>
<iframe style="display:none" onload="myFunction()" src="http://www.w3schools.com"></iframe>
<p id="demo"></p>
<script>
function myFunction() {
document.getElementById("demo").innerHTML = "Iframe is loaded.";
}

You can use the spread operator:
<button style={{...styles.panel.button,...styles.panel.backButton}}>Back</button
Hive tables may not necessarily be stored in a warehouse (since you can create tables located anywhere on the HDFS).
You should use DESCRIBE FORMATTED <table_name>
command.
hive -S -e "describe formatted <table_name> ;" | grep 'Location' | awk '{ print $NF }'
Please note that partitions may be stored in different places and to get the location of the alpha=foo/beta=bar
partition you'd have to add partition(alpha='foo',beta='bar')
after <table_name>
.
You need to have at least the same number of columns and each column has to be defined in exactly the same way, i.e. a varchar column can't be inserted into an int column.
For bulk transfer, check the documentation for the SQL implementation you're using. There are often tools available to bulk transfer data from one table to another. For SqlServer 2005, for example, you could use the SQL Server Import and Export Wizard. Right-click on the database you're trying to move data around in and click Export to access it.
There are many possibilities to do this in R. Here are some of them:
df <- read.table(header = TRUE, text = 'Gene Value
A 12
A 10
B 3
B 5
B 6
C 1
D 3
D 4')
# aggregate
aggregate(df$Value, by = list(df$Gene), max)
aggregate(Value ~ Gene, data = df, max)
# tapply
tapply(df$Value, df$Gene, max)
# split + lapply
lapply(split(df, df$Gene), function(y) max(y$Value))
# plyr
require(plyr)
ddply(df, .(Gene), summarise, Value = max(Value))
# dplyr
require(dplyr)
df %>% group_by(Gene) %>% summarise(Value = max(Value))
# data.table
require(data.table)
dt <- data.table(df)
dt[ , max(Value), by = Gene]
# doBy
require(doBy)
summaryBy(Value~Gene, data = df, FUN = max)
# sqldf
require(sqldf)
sqldf("select Gene, max(Value) as Value from df group by Gene", drv = 'SQLite')
# ave
df[as.logical(ave(df$Value, df$Gene, FUN = function(x) x == max(x))),]
It is possible to print a 15 decimal number in C++ using the following:
#include <iomanip>
#include <iostream>
cout << fixed << setprecision(15) << " The Real_Pi is: " << real_pi << endl;
cout << fixed << setprecision(15) << " My Result_Pi is: " << my_pi << endl;
cout << fixed << setprecision(15) << " Processing error is: " << Error_of_Computing << endl;
cout << fixed << setprecision(15) << " Processing time is: " << End_Time-Start_Time << endl;
_getch();
return 0;
It is possible using ConfigTransform
build target available as a Nuget package - https://www.nuget.org/packages/CodeAssassin.ConfigTransform/
All "web.*.config" transform files will be transformed and output as a series of "web.*.config.transformed" files in the build output directory regardless of the chosen build configuration.
The same applies to "app.*.config" transform files in non-web projects.
and then adding the following target to your *.csproj
.
<Target Name="TransformActiveConfiguration" Condition="Exists('$(ProjectDir)/Web.$(Configuration).config')" BeforeTargets="Compile" >
<TransformXml Source="$(ProjectDir)/Web.Config" Transform="$(ProjectDir)/Web.$(Configuration).config" Destination="$(TargetDir)/Web.config" />
</Target>
Posting an answer as this is the first Stackoverflow post that appears in Google on the subject.
Please read and strongly consider my advice in the comments of your post. That being said, if you still have a good reason to do this, check out this list of crypto modules for Node. It has modules for dealing with both sha1 and base64.
create view sampleView as
select field1, field2, ...
from dbo.MyTableValueFunction
Note that even if your MyTableValueFunction doesn't accept any parameters, you still need to include parentheses after it, i.e.:
... from dbo.MyTableValueFunction()
Without the parentheses, you'll get an "Invalid object name" error.
Most of the answers above didn't work. I was trying to upload image to S3 bucket using react-s3 and I got this
Cross-Origin Request Blocked
error.
All you have to do is add CORS Config in s3 Bucket Go to S3 Bucket -> Persmission -> CORS Configuration And paste the below
<CORSConfiguration>
<CORSRule>
<AllowedOrigin>*</AllowedOrigin>

I prefer combining DATEADD
and DATEDIFF
functions like this:
GROUP BY DATEADD(MONTH, DATEDIFF(MONTH, 0, Created),0)
Together, these two functions zero-out the date component smaller than the specified datepart (i.e. MONTH
in this example).
You can change the datepart bit to YEAR
, WEEK
, DAY
, etc... which is super handy.
Your original SQL query would then look something like this (I can't test it as I don't have your data set, but it should put you on the right track).
DECLARE @start [datetime] = '2010-04-01';
SELECT
ItemID,
UserID,
DATEADD(MONTH, DATEDIFF(MONTH, 0, Created),0) [Month],
IsPaid,
SUM(Amount)
FROM LIVE L
INNER JOIN Payments I ON I.LiveID = L.RECORD_KEY
WHERE UserID = 16178
AND PaymentDate > @start
One more thing: the Month
column is typed as a DateTime
which is also a nice advantage if you need to further process that data or map it .NET object for example.
Let's say you have two activities.
And on click of a Button, this happens.
1) Enable Content Transition
Go to your style.xml
and add this line to enable the content transition.
<item name="android:windowContentTransitions">true</item>
2) Write Default Enter and Exit Transition for your AllCastActivity
public void setAnimation()
{
if(Build.VERSION.SDK_INT>20) {
Slide slide = new Slide();
slide.setSlideEdge(Gravity.LEFT);
slide.setDuration(400);
slide.setInterpolator(new AccelerateDecelerateInterpolator());
getWindow().setExitTransition(slide);
getWindow().setEnterTransition(slide);
}
}
3) Start Activity with Intent
Write this method in Your MovieDetailActivity
to start AllCastActivity
public void startActivity(){
Intent i = new Intent(FirstActivity.this, SecondActivity.class);
i.putStringArrayListExtra(MOVIE_LIST, movie.getImages());
if(Build.VERSION.SDK_INT>20)
{
ActivityOptions options = ActivityOptions.makeSceneTransitionAnimation(BlankActivity.this);
startActivity(i,options.toBundle());
}
else {
startActivity(i);
}
}
put your setAnimation()
method before setContentView()
method otherwise the animation will not work.
So your AllCastActivity.java
should look like this
class AllCastActivity extends AppcompatActivity {
@Override
protected void onCreate(Bundle savedInstaceState)
{
super.onCreate(savedInstaceState);
setAnimation();
setContentView(R.layout.all_cast_activity);
.......
}
private void setAnimation(){
if(Build.VERSION.SDK_INT>20) {
Slide slide = new Slide();
slide.setSlideEdge(Gravity.LEFT);
..........
}
}
This one is similar to @Wilhelm's solution. The loop automates based on a range created by evaluating the populated date column. This was slapped together based strictly on the conversation here and screenshots.
Please note: This assumes that the headers will always be on the same row (row 8). Changing the first row of data (moving the header up/down) will cause the range automation to break unless you edit the range block to take in the header row dynamically. Other assumptions include that VOL and CAPACITY formula column headers are named "Vol" and "Cap" respectively.
Sub Loop3()
Dim dtCnt As Long
Dim rng As Range
Dim frmlas() As String
Application.ScreenUpdating = False
'The following code block sets up the formula output range
dtCnt = Sheets("Loop").Range("A1048576").End(xlUp).Row 'lowest date column populated
endHead = Sheets("Loop").Range("XFD8").End(xlToLeft).Column 'right most header populated
Set rng = Sheets("Loop").Range(Cells(9, 2), Cells(dtCnt, endHead)) 'assigns range for automation
ReDim frmlas(1) 'array assigned to formula strings
'VOL column formula
frmlas(0) = "VOL FORMULA"
'CAPACITY column formula
frmlas(1) = "CAP FORMULA"
For i = 1 To rng.Columns.count
If rng(0, i).Value = "Vol" Then 'checks for volume formula column
For j = 1 To rng.Rows.count
rng(j, i).Formula= frmlas(0) 'inserts volume formula
Next j
ElseIf rng(0, i).Value = "Cap" Then 'checks for capacity formula column
For j = 1 To rng.Rows.count
rng(j, i).Formula = frmlas(1) 'inserts capacity formula
Next j
End If
Next i
Application.ScreenUpdating = True
End Sub
GroupBy using in Hibernate
This is the resulting code
public Map getStateCounts(final Collection ids) {
HibernateSession hibernateSession = new HibernateSession();
Session session = hibernateSession.getSession();
Criteria criteria = session.createCriteria(DownloadRequestEntity.class)
.add(Restrictions.in("id", ids));
ProjectionList projectionList = Projections.projectionList();
projectionList.add(Projections.groupProperty("state"));
projectionList.add(Projections.rowCount());
criteria.setProjection(projectionList);
List results = criteria.list();
Map stateMap = new HashMap();
for (Object[] obj : results) {
DownloadState downloadState = (DownloadState) obj[0];
stateMap.put(downloadState.getDescription().toLowerCase() (Integer) obj[1]);
}
hibernateSession.closeSession();
return stateMap;
}
You could use an image submit button:
<input type="image" id="saveform" src="logg.png " alt="Submit Form" />
You should be using the thread pool (or async delgates, which in turn use the thread pool) so that the system can decide how many threads should run.
The HTML attribute required="required"
is a statement telling the browser that this field is required in order for the form to be valid. (required="required"
is the XHTML form, just using required
is equivalent)
The Angular attribute ng-required="yourCondition"
means 'isRequired(yourCondition)' and sets the HTML attribute dynamically for you depending on your condition.
Also note that the HTML version is confusing, it is not possible to write something conditional like required="true"
or required="false"
, only the presence of the attribute matters (present means true) ! This is where Angular helps you out with ng-required
.
Although C# doesn't have any direct equivalent for the general case, C# 3 gain object initializer syntax for constructor calls:
var foo = new Foo { Property1 = value1, Property2 = value2, etc };
See chapter 8 of C# in Depth for more details - you can download it for free from Manning's web site.
(Disclaimer - yes, it's in my interest to get the book into more people's hands. But hey, it's a free chapter which gives you more information on a related topic...)
I have written a quick guide on how to install the latest versions of Python 2 and Python 3 on CentOS 6 and CentOS 7. It currently covers Python 2.7.13 and Python 3.6.0:
# Start by making sure your system is up-to-date:
yum update
# Compilers and related tools:
yum groupinstall -y "development tools"
# Libraries needed during compilation to enable all features of Python:
yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel expat-devel
# If you are on a clean "minimal" install of CentOS you also need the wget tool:
yum install -y wget
The next steps depend on the version of Python you're installing.
For Python 2.7.14:
wget http://python.org/ftp/python/2.7.14/Python-2.7.14.tar.xz
tar xf Python-2.7.14.tar.xz
cd Python-2.7.14
./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make && make altinstall
# Strip the Python 2.7 binary:
strip /usr/local/lib/libpython2.7.so.1.0
For Python 3.6.3:
wget http://python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz
tar xf Python-3.6.3.tar.xz
cd Python-3.6.3
./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make && make altinstall
# Strip the Python 3.6 binary:
strip /usr/local/lib/libpython3.6m.so.1.0
To install Pip:
# First get the script:
wget https://bootstrap.pypa.io/get-pip.py
# Then execute it using Python 2.7 and/or Python 3.6:
python2.7 get-pip.py
python3.6 get-pip.py
# With pip installed you can now do things like this:
pip2.7 install [packagename]
pip2.7 install --upgrade [packagename]
pip2.7 uninstall [packagename]
You are not supposed to change the system version of Python because it will break the system (as you found out). Installing other versions works fine as long as you leave the original system version alone. This can be accomplished by using a custom prefix (for example /usr/local
) when running configure, and using make altinstall
(instead of the normal make install
) when installing your build of Python.
Having multiple versions of Python available is usually not a big problem as long as you remember to type the full name including the version number (for example "python2.7" or "pip2.7"). If you do all your Python work from a virtualenv the versioning is handled for you, so make sure you install and use virtualenv!
Chrome needs a user interaction for the video to be autoplayed or played via js (video.play()). But the interaction can be of any kind, in any moment. If you just click random on the page, the video will autoplay. I resolved then, adding a button (only on chrome browsers) that says "enable video autoplay". The button does nothing, but just clicking it, is the required user interaction for any further video.
Just attention, as of today, 2018, due to api changing over the years. removeAttr are depricated, NOT working anymore!
Jquery Check or unCheck a checkbox:
Bad, not working any more.
$('#add_user_certificate_checkbox').removeAttr("checked");
$('#add_user_certificate_checkbox').attr("checked","checked");
Instead you should do:
$('#add_user_certificate_checkbox').prop('checked', true);
$('#add_user_certificate_checkbox').prop('checked', false);
The goal of InputStream
and OutputStream
is to abstract different ways to input and output: whether the stream is a file, a web page, or the screen shouldn't matter. All that matters is that you receive information from the stream (or send information into that stream.)
InputStream
is used for many things that you read from.
OutputStream
is used for many things that you write to.
Here's some sample code. It assumes the InputStream instr
and OutputStream osstr
have already been created:
int i;
while ((i = instr.read()) != -1) {
osstr.write(i);
}
instr.close();
osstr.close();
Example: index = False
import pandas as pd
writer = pd.ExcelWriter("dataframe.xlsx", engine='xlsxwriter')
dataframe.to_excel(writer,sheet_name = dataframe, index=False)
writer.save()
I added this to the Button of a datagrid to get the values of the cells in the row that the user is clicking:
string DGCell = dataGridView1.Rows[e.RowIndex].Cells[X].Value.ToString();
where X is the cell you want to check. Datagrid column count starts at 1 not 0 in my case. Not sure if it is default of a datagrid or because I am using SQL to populate the info.
Because there are more than one way to skin a cat, here's my approach:
Code:
#!/usr/bin/env lua
local content = [=[
Lorem ipsum dolor sit amet, consectetur adipisicing elit,
sed do eiusmod tempor incididunt ut labore et dolore magna
aliqua. Ut enim ad minim veniam, quis nostrud exercitation
ullamco laboris nisi ut aliquip ex ea commodo consequat.
]=]
local function split(str, sep)
local result = {}
local regex = ("([^%s]+)"):format(sep)
for each in str:gmatch(regex) do
table.insert(result, each)
end
return result
end
local lines = split(content, "\n")
for _,line in ipairs(lines) do
print(line)
end
Output:
Lorem ipsum dolor sit amet, consectetur adipisicing elit,
sed do eiusmod tempor incididunt ut labore et dolore magna
aliqua. Ut enim ad minim veniam, quis nostrud exercitation
ullamco laboris nisi ut aliquip ex ea commodo consequat.
Explanation:
The gmatch
function works as an iterator, it fetches all the strings that match regex
. The regex
takes all characters until it finds a separator.

I would give your tds a specific class, e.g. data-cell, and then use something like this:
$("td.data-cell").each(function () {
// 'this' is now the raw td DOM element
var txt = $(this).html();
});
Using JQuery would take care of that browser inconsistency. With the jquery library included in your project simply write:
$('#yourDivName').html('yourtHTML');
You may also consider using:
$('#yourDivName').append('yourtHTML');
This will add your gallery as the last item in the selected div. Or:
$('#yourDivName').prepend('yourtHTML');
This will add it as the first item in the selected div.
See the JQuery docs for these functions:
This is one way to do it using a list comprehension, though it's increasingly wasteful as the length of the rpt
string increases.
def repeat(rpt, length):
return ''.join([rpt for x in range(0, (len(rpt) % length))])[:length]
If you using roles you could check for ROLE_USER
that is the solution i use:
if (TRUE === $this->get('security.authorization_checker')->isGranted('ROLE_USER')) {
// user is logged in
}
In my case, I took an android
project from one computer to another and had this problem. What worked for me was a combination of some of the answers I've seen:
Mine ran fine after these steps.
If the problem still persists even after putting the after build in the correct project try using "copy" instead of xcopy. This worked for me.
For all users on a specific database, do the following:
# psql
\c your_database
select grantee, table_catalog, privilege_type, table_schema, table_name from information_schema.table_privileges order by grantee, table_schema, table_name;
try this
declare @v varchar(250) = 'test.a,1 ;hheuw-20;'
-- LF ;
select len(replace(@v,';','11'))-len(@v)
Although you must still either explicitly compare an optional with nil
or use optional binding to additionally extract its value (i.e. optionals are not implicitly converted into Boolean values), it's worth noting that Swift 2 has added the guard
statement to help avoid the pyramid of doom when working with multiple optional values.
In other words, your options now include explicitly checking for nil
:
if xyz != nil {
// Do something with xyz
}
Optional binding:
if let xyz = xyz {
// Do something with xyz
// (Note that we can reuse the same variable name)
}
And guard
statements:
guard let xyz = xyz else {
// Handle failure and then exit this code block
// e.g. by calling return, break, continue, or throw
return
}
// Do something with xyz, which is now guaranteed to be non-nil
Note how ordinary optional binding can lead to greater indentation when there is more than one optional value:
if let abc = abc {
if let xyz = xyz {
// Do something with abc and xyz
}
}
You can avoid this nesting with guard
statements:
guard let abc = abc else {
// Handle failure and then exit this code block
return
}
guard let xyz = xyz else {
// Handle failure and then exit this code block
return
}
// Do something with abc and xyz
The top rated solutions didn't seem to work for me. My solution is below:
brew uninstall nvm
brew install nvm
In Terminal, follow the steps below(these are also listed when installing nvm via homebrew):
mkdir ~/.nvm cp $(brew --prefix nvm)/nvm-exec ~/.nvm/ export NVM_DIR=~/.nvm source $(brew --prefix nvm)/nvm.sh
The steps outlined above will add NVM's working directory to your $HOME path, copy nvm-exec to NVM's working directory and add to $HOME/.bashrc, $HOME/.zshrc, or your shell's equivalent configuration file.(again taken from whats listed on an NVM install using homebrew)
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 :)
I don't know if this is what you're looking for, but you can export the results to Excel like this:
In the results pane, click the top-left cell to highlight all the records, and then right-click the top-left cell and click "Save Results As". One of the export options is CSV.
You might give this a shot too:
INSERT INTO OPENROWSET
('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=c:\Test.xls;','SELECT productid, price FROM dbo.product')
Lastly, you can look into using SSIS (replaced DTS) for data exports. Here is a link to a tutorial:

To save the result as CSV file with column headers, one can follow the steps shown below:
This works for me. I'm sorry if I cannot remember the source. It is probably from a man page.
#include <ftw.h>
int AnalizeDirectoryElement (const char *fpath,
const struct stat *sb,
int tflag,
struct FTW *ftwbuf) {
if (tflag == FTW_F) {
std::string strFileName(fpath);
DoSomethingWith(strFileName);
}
return 0;
}
void WalkDirectoryTree (const char * pchFileName) {
int nFlags = 0;
if (nftw(pchFileName, AnalizeDirectoryElement, 20, nFlags) == -1) {
perror("nftw");
}
}
int main() {
WalkDirectoryTree("some_dir/");
}
Can I just ask about the long term need for this facility - is it for debuging purposes?
If so, then you may want to consider using a proper debugger, such as the one found in Visual Studio, as this allows you to step through the procedure in a more controlled way, and avoids having to constantly add/remove PRINT statement from the procedure.
Just my opinion, but I prefer the debugger approach - for code and databases.
Popen expect a list of strings for non-shell calls and a string for shell calls.
Call subprocess.Popen with shell=True:
process = subprocess.Popen(command, stdout=tempFile, shell=True)
Hopefully this solves your issue.
