It is useful if you are building a kernel - where do you place the kernel code you read from disk or the pagetable? You need to know where to jump to.
Or in other, very rare circumstances such as when you have loads of allocated room and want to place a few structures behind each other. They can be packed this way without the need for the offsetof() operator. There are other tricks for that too, though.
I also believe some STL implementations make use of placement new, like std::vector. They allocate room for 2^n elements that way and don't need to always realloc.
I use environment for that. It works automatically and you don't have to create new injectable service and most usefull for me, don't need to import via constructor.
1) Create environment variable in your environment.ts
export const environment = {
...
// runtime variables
isContentLoading: false,
isDeployNeeded: false
}
2) Import environment.ts in *.ts file and create public variable (i.e. "env") to be able to use in html template
import { environment } from 'environments/environment';
@Component(...)
export class TestComponent {
...
env = environment;
}
3) Use it in template...
<app-spinner *ngIf='env.isContentLoading'></app-spinner>
in *.ts ...
env.isContentLoading = false
(or just environment.isContentLoading in case you don't need it for template)
You can create your own set of globals within environment.ts like so:
export const globals = {
isContentLoading: false,
isDeployNeeded: false
}
and import directly these variables (y)

Best Way to Refresh Adapter/ListView on Android
Not only calling notifyDataSetChanged() will refresh the ListView data, setAdapter()
must be called before to load the information correctly:
listView.setAdapter(adapter);
adapter.notifyDataSetChanged();
The trick is passing the both the source and destination arrays by reference.
function flatten_array(&$arr, &$dst) {
if(!isset($dst) || !is_array($dst)) {
$dst = array();
}
if(!is_array($arr)) {
$dst[] = $arr;
} else {
foreach($arr as &$subject) {
flatten_array($subject, $dst);
}
}
}
$recursive = array('1', array('2','3',array('4',array('5','6')),'7',array(array(array('8'),'9'),'10')));
echo "Recursive: \r\n";
print_r($recursive);
$flat = null;
flatten_array($recursive, $flat);
echo "Flat: \r\n";
print_r($flat);
// If you change line 3 to $dst[] = &$arr; , you won't waste memory,
// since all you're doing is copying references, and imploding the array
// into a string will be both memory efficient and fast:)
echo "String:\r\n";
echo implode(',',$flat);
'\0' is the way to go. It's a character, which is what's wanted in a string and has the null value.
When we say null terminated string in C/C++, it really means 'zero terminated string'. The NULL macro isn't intended for use in terminating strings.

Most probably you might have parameterized constructor in your controller and whatever dependency resolver you are using is not able to resolve the dependency properly. You need to put break-point where the dependency resolver method is written and you will get the exact error in inner exception.
Regarding to sampopes answer from Jun 6 '14 at 11:59:
I have insert a css style with font-size of 20px to display the excel data greater. In sampopes code the leading <tr>
tags are missing, so i first output the headline and than the other tables lines within a loop.
function fnExcelReport()
{
var tab_text = '<table border="1px" style="font-size:20px" ">';
var textRange;
var j = 0;
var tab = document.getElementById('DataTableId'); // id of table
var lines = tab.rows.length;
// the first headline of the table
if (lines > 0) {
tab_text = tab_text + '<tr bgcolor="#DFDFDF">' + tab.rows[0].innerHTML + '</tr>';
}
// table data lines, loop starting from 1
for (j = 1 ; j < lines; j++) {
tab_text = tab_text + "<tr>" + tab.rows[j].innerHTML + "</tr>";
}
tab_text = tab_text + "</table>";
tab_text = tab_text.replace(/<A[^>]*>|<\/A>/g, ""); //remove if u want links in your table
tab_text = tab_text.replace(/<img[^>]*>/gi,""); // remove if u want images in your table
tab_text = tab_text.replace(/<input[^>]*>|<\/input>/gi, ""); // reomves input params
// console.log(tab_text); // aktivate so see the result (press F12 in browser)
var ua = window.navigator.userAgent;
var msie = ua.indexOf("MSIE ");
// if Internet Explorer
if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) {
txtArea1.document.open("txt/html","replace");
txtArea1.document.write(tab_text);
txtArea1.document.close();
txtArea1.focus();
sa = txtArea1.document.execCommand("SaveAs", true, "DataTableExport.xls");
}
else // other browser not tested on IE 11
sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));
return (sa);
}
When you make the input, set it to be readonly.
<input type="text" name="datepicker" id="datepicker" readonly="readonly" />
Ok what you probably want will be provide to you by result of:
in CSS:
div { column-count: 2; }
in html:
<div> some text, bla bla bla </div>
In CSS you make div to split your paragraph on to column, you can make them 3, 4...
If you want to have many differend paragraf like that, then put id or class in your div:
OP's solution to his problem, as he says, has dubious output. That code still shows confusion about representations of time. To clear up this confusion, and make code that won't lead to wrong times, consider this extension of what he did:
public static void _testDateFormatting() {
SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));
SimpleDateFormat sdfGMT2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");
sdfGMT2.setTimeZone(TimeZone.getTimeZone("GMT"));
SimpleDateFormat sdfLocal1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
SimpleDateFormat sdfLocal2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");
try {
Date d = new Date();
String s1 = d.toString();
String s2 = sdfLocal1.format(d);
// Store s3 or s4 in database.
String s3 = sdfGMT1.format(d);
String s4 = sdfGMT2.format(d);
// Retrieve s3 or s4 from database, using LOCAL sdf.
String s5 = sdfLocal1.parse(s3).toString();
//EXCEPTION String s6 = sdfLocal2.parse(s3).toString();
String s7 = sdfLocal1.parse(s4).toString();
String s8 = sdfLocal2.parse(s4).toString();
// Retrieve s3 from database, using GMT sdf.
// Note that this is the SAME sdf that created s3.
Date d2 = sdfGMT1.parse(s3);
String s9 = d2.toString();
String s10 = sdfGMT1.format(d2);
String s11 = sdfLocal2.format(d2);
} catch (Exception e) {
e.printStackTrace();
}
}
examining values in a debugger:
s1 "Mon Sep 07 06:11:53 EDT 2015" (id=831698113128)
s2 "2015.09.07 06:11:53" (id=831698114048)
s3 "2015.09.07 10:11:53" (id=831698114968)
s4 "2015.09.07 10:11:53 GMT+00:00" (id=831698116112)
s5 "Mon Sep 07 10:11:53 EDT 2015" (id=831698116944)
s6 -- omitted, gave parse exception
s7 "Mon Sep 07 10:11:53 EDT 2015" (id=831698118680)
s8 "Mon Sep 07 06:11:53 EDT 2015" (id=831698119584)
s9 "Mon Sep 07 06:11:53 EDT 2015" (id=831698120392)
s10 "2015.09.07 10:11:53" (id=831698121312)
s11 "2015.09.07 06:11:53 EDT" (id=831698122256)
sdf2 and sdfLocal2 include time zone, so we can see what is really going on. s1 & s2 are at 06:11:53 in zone EDT. s3 & s4 are at 10:11:53 in zone GMT -- equivalent to the original EDT time. Imagine we save s3 or s4 in a data base, where we are using GMT for consistency, so we can have times from anywhere in the world, without storing different time zones.
s5 parses the GMT time, but treats it as a local time. So it says "10:11:53" -- the GMT time -- but thinks it is 10:11:53 in local time. Not good.
s7 parses the GMT time, but ignores the GMT in the string, so still treats it as a local time.
s8 works, because now we include GMT in the string, and the local zone parser uses it to convert from one time zone to another.
Now suppose you don't want to store the zone, you want to be able to parse s3, but display it as a local time. The answer is to parse using the same time zone it was stored in -- so use the same sdf as it was created in, sdfGMT1. s9, s10, & s11 are all representations of the original time. They are all "correct". That is, d2 == d1. Then it is only a question of how you want to DISPLAY it. If you want to display what is stored in DB -- GMT time -- then you need to format it using a GMT sdf. Ths is s10.
So here is the final solution, if you don't want to explicitly store with " GMT" in the string, and want to display in GMT format:
public static void _testDateFormatting() {
SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));
try {
Date d = new Date();
String s3 = sdfGMT1.format(d);
// Store s3 in DB.
// ...
// Retrieve s3 from database, using GMT sdf.
Date d2 = sdfGMT1.parse(s3);
String s10 = sdfGMT1.format(d2);
} catch (Exception e) {
e.printStackTrace();
}
}
Every time you are creating plots you might get this error - "Error in plot.new() : figure margins too large
". To avoid such errors you can first check par("mar")
output. You should be getting:
[1] 5.1 4.1 4.1 2.1
To change that write:
par(mar=c(1,1,1,1))
This should rectify the error. Or else you can change the values accordingly.
Hope this works for you.
ok, so my problem was that I tried to install the package with yum which is the primary tool for getting, installing, deleting, querying, and managing Red Hat Enterprise Linux RPM software packages from official Red Hat software repositories, as well as other third-party repositories.
But I'm using ubuntu and The usual way to install packages on the command line in Ubuntu is with apt-get. so the right command was:

JS Offers array functions which allow you to achieve this relatively easily. They are the following:
Array.prototype.filter
: Takes a callback function which is a test, the array is then iterated over with is callback and filtered according to this callback. A new filtered array is returned.Array.prototype.some
: Takes a callback function which is a test, the array is then iterated over with is callback and if any element passes the test, the boolean true is returned. Otherwise false is returnedThe specifics are best explained via an example:
vendors = [_x000D_
{_x000D_
Name: 'Magenic',_x000D_
ID: 'ABC'_x000D_
},_x000D_
{_x000D_
Name: 'Microsoft',_x000D_
ID: 'DEF'_x000D_
} //and so on goes array... _x000D_
];_x000D_
_x000D_
// filter returns a new array, we instantly check if the length _x000D_
// is longer than zero of this newly created array_x000D_
if (vendors.filter(company => company.Name === 'Magenic').length ) {_x000D_
console.log('I contain Magenic');_x000D_
}_x000D_
_x000D_
// some would be a better option then filter since it directly returns a boolean_x000D_
if (vendors.some(company => company.Name === 'Magenic')) {_x000D_
console.log('I also contain Magenic');_x000D_
}
_x000D_
These 2 function are ES6
function, not all browsers might support them. To overcome this you can use a polyfill. Here is the polyfill for Array.prototype.some
(from MDN):
if (!Array.prototype.some) {_x000D_
Array.prototype.some = function(fun, thisArg) {_x000D_
'use strict';_x000D_
_x000D_
if (this == null) {_x000D_
throw new TypeError('Array.prototype.some called on null or undefined');_x000D_
}_x000D_
_x000D_
if (typeof fun !== 'function') {_x000D_
throw new TypeError();_x000D_
}_x000D_
_x000D_
var t = Object(this);_x000D_
var len = t.length >>> 0;_x000D_
_x000D_
for (var i = 0; i < len; i++) {_x000D_
if (i in t && fun.call(thisArg, t[i], i, t)) {_x000D_
return true;_x000D_
}_x000D_
}_x000D_
_x000D_
return false;_x000D_

To prevent this, make sure every BEGIN TRANSACTION has COMMIT
The following will say successful but will leave uncommitted transactions:
BEGIN TRANSACTION
BEGIN TRANSACTION
<SQL_CODE?
COMMIT
Closing query windows with uncommitted transactions will prompt you to commit your transactions. This will generally resolve the Error 1222 message.
Thought this might help to someone, it happens because "When the number of data queries is greater than 1".reference
Another nice way to time things is to use the with python structure.
with structure is automatically calling __enter__ and __exit__ methods which is exactly what we need to time things.
Let's create a Timer class.
from time import time
class Timer():
def __init__(self, message):
self.message = message
def __enter__(self):
self.start = time()
return None # could return anything, to be used like this: with Timer("Message") as value:
def __exit__(self, type, value, traceback):
elapsed_time = (time() - self.start) * 1000
print(self.message.format(elapsed_time))
Then, one can use the Timer class like this:
with Timer("Elapsed time to compute some prime numbers: {}ms"):
primes = []
for x in range(2, 500):
if not any(x % p == 0 for p in primes):
primes.append(x)
print("Primes: {}".format(primes))
The result is the following:
Primes: [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499]
Elapsed time to compute some prime numbers: 5.01704216003418ms
You could also do the following:
// untested
Calendar cal = GregorianCalendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, 23);// I might have the wrong Calendar constant...
cal.set(Calendar.MONTH, 8);// -1 as month is zero-based
cal.set(Calendar.YEAR, 2009);
Timestamp tstamp = new Timestamp(cal.getTimeInMillis());
Hmmm... I suppose the closest thing to an enum would be a dictionary, defined either like this:
months = {
'January': 1,
'February': 2,
...
}
or
months = dict(
January=1,
February=2,
...
)
Then, you can use the symbolic name for the constants like this:
mymonth = months['January']
There are other options, like a list of tuples, or a tuple of tuples, but the dictionary is the only one that provides you with a "symbolic" (constant string) way to access the value.
Edit: I like Alexandru's answer too!
Have tried most of the examples here if not all but none seem to be working in my case. After struggling for quite some time I have tried using as.character() on the factor column to change it to a col with strings which seems to working just fine.
Not sure for performance issues.
As simply as:
if (numbers.isEmpty()) {...}
Note that a quick look at the documentation would have given you that information.
git reflog show
should show you the history of HEAD. You can use that to figure out where you were before the pull
. Then you can reset
your HEAD
to that commit.
Beans.xml or file.XML is not placed under proper path. You should add the XML file under the resource folder, if you have a Maven project. src -> main -> java -> resources
I did this by using data attributes. Is a lot cleaner than other methods attempting to explode etc.
HTML
<select class="example">
<option value="1" data-value="A">One</option>
<option value="2" data-value="B">Two</option>
<option value="3" data-value="C">Three</option>
<option value="4" data-value="D">Four</option>
</select>
JS
$('select.example').change(function() {
var other_val = $('select.example option[value="' + $(this).val() + '"]').data('value');
console.log(other_val);
});
The problem is that in IE (which is what I presume you're testing in), the <iframe>
element has a document
property that refers to the document containing the iframe, and this is getting used before the contentDocument
or contentWindow.document
properties. What you need is:
function GetDoc(x) {
return x.contentDocument || x.contentWindow.document;
}
Also, document.all
is not available in all browsers and is non-standard. Use document.getElementById()
instead.
I will show visually the problem, using the great example from James answer and adding the alternative solution.
When you do the follow query, without the FETCH
:
Select e from Employee e
join e.phones p
where p.areaCode = '613'
You will have the follow results from Employee
as you expected:
EmployeeId | EmployeeName | PhoneId | PhoneAreaCode |
---|---|---|---|
1 | James | 5 | 613 |
1 | James | 6 | 416 |
But when you add the FETCH
word on JOIN
, this is what happens:
EmployeeId | EmployeeName | PhoneId | PhoneAreaCode |
---|---|---|---|
1 | James | 5 | 613 |
The generated SQL is the same for the two queries, but the Hibernate removes on memory the 416
register when you use WHERE
on the FETCH
join.
So, to bring all phones and apply the WHERE
correctly, you need to have two JOIN
s: one for the WHERE
and another for the FETCH
. Like:
Select e from Employee e
join e.phones p
join fetch e.phones //no alias, to not commit the mistake
where p.areaCode = '613'
Try like this.
You must give a function as value to onClick()
You button:
<button type="button" onClick={ refreshPage }> <span>Reload</span> </button>
refreshPage function:
function refreshPage(){
window.location.reload();
}
Your cells object is not fully qualified. You need to add a DOT
before the cells object. For example
With Worksheets("Cable Cards")
.Range(.Cells(RangeStartRow, RangeStartColumn), _
.Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues
Similarly, fully qualify all your Cells object.
You can create a serial-over-LAN (SOL) connection by using socat. It can be used to 'forward' a ttyS to another machine so it appears as a local one or you can access it via a TCP/IP port.
// will return dates array
function returnBetweenDates( $startDate, $endDate ){
$startStamp = strtotime( $startDate );
$endStamp = strtotime( $endDate );
if( $endStamp > $startStamp ){
while( $endStamp >= $startStamp ){
$dateArr[] = date( 'Y-m-d', $startStamp );
$startStamp = strtotime( ' +1 day ', $startStamp );
}
return $dateArr;
}else{
return $startDate;
}
}
returnBetweenDates( '2014-09-16', '2014-09-26' );
// print_r( returnBetweenDates( '2014-09-16', '2014-09-26' ) );
it will return array like below:

[7] => 2014-09-23
[8] => 2014-09-24
[9] => 2014-09-25
[10] => 2014-09-26

The Exception means that the socket was closed unexpectedly from the other side. Since you are calling a web service, this should not happen - most likely you're sending a request that triggers a bug in the web service.
Try logging the entire request in those cases, and see if you notice anything unusual. Otherwise, get in contact with the web service provider and send them your logged problematical request.
It is impossible, and unnecessary, to know the motivation for using "
in element content, but possible motives include: misunderstanding of HTML rules; use of software that generates such code (probably because its author thought it was “safer”); and misunderstanding of the meaning of "
: many people seem to think it produces “smart quotes” (they apparently never looked at the actual results).
Anyway, there is never any need to use "
in element content in HTML (XHTML or any other HTML version). There is nothing in any HTML specification that would assign any special meaning to the plain character " there.
As the question says, it has its role in attribute values, but even in them, it is mostly simpler to just use single quotes as delimiters if the value contains a double quote, e.g. alt='Greeting: "Hello, World!"'
or, if you are allowed to correct errors in natural language texts, to use proper quotation marks, e.g. alt="Greeting: “Hello, World!”"
if you really want an array instead you can use:
$getvidids->result_array()
which would return the same information as an associative array.
The quantile()
function will do much of what you probably want, but since the question was ambiguous, I will provide an alternate answer that does something slightly different from quantile()
.
ecdf(infert$age)(infert$age)
will generate a vector of the same length as infert$age
giving the proportion of infert$age
that is below each observation. You can read the ecdf
documentation, but the basic idea is that ecdf()
will give you a function that returns the empirical cumulative distribution. Thus ecdf(X)(Y)
is the value of the cumulative distribution of X at the points in Y. If you wanted to know just the probability of being below 30 (thus what percentile 30 is in the sample), you could say
ecdf(infert$age)(30)
The main difference between this approach and using the quantile()
function is that quantile()
requires that you put in the probabilities to get out the levels, and this requires that you put in the levels to get out the probabilities.

To take database backup you need to create New Server Instance
(If not available) within Server Administration
.
Steps to Create New Server Instance
:
New Server Instance
option within Server Administrator
.After creating new server instance , it will be available in Server Administration
list. Double click on Server instance you have created OR Click on Manage Import/Export
option and Select Server Instance.
Now, From DATA EXPORT/RESTORE
select DATA EXPORT
option,Select Schema and Schema Object for backup.
You can take generate backup file in different way as given below-
Q.1) Backup file(.sql) contains both Create Table statements and Insert into Table Statements
ANS:
Q.2) Backup file(.sql) contains only Create Table Statements, not Insert into Table statements for all tables
ANS:
Select Skip Table Data(no-data)
option
Select Start Export Option
Q.3) Backup file(.sql) contains only Insert into Table Statements, not Create Table statements for all tables
ANS:
Tables
Panel- select no-create info-Do not write CREATE TABLE statement that re-create each dumped table
option.This opens up something like this
For this your android application must have uploaded into the android market. when you upload it on the android market then use the following code to open the market with your android application.
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=<packagename>"));
startActivity(intent);
If you want it to download and install from your own server then use the following code
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.example.com/sample/test.apk"));
startActivity(intent);
Start with npm root
-- it will show you the root folder for NPM packages for the current user.
Add -g
and you get a global folder. Don't forget to substract node_modules
.
Use npm config
/ npm config -g
and check that it'd create you a new .npmrc
/ npmrc
file for you.
Tested on Windows 10 Pro, NPM v.6.4.1:
C:\Users\%username%\AppData\Roaming\npm\etc\npmrc
C:\Users\%username%\.npmrc
C:\Program Files\nodejs\node_modules\npm\npmrc

Use prepared statements. Those keep the data and syntax apart, which removes the need for escaping MySQL data. See e.g. this tutorial.
Note however:
If you issue SET TRANSACTION ISOLATION LEVEL in a stored procedure or trigger, when the object returns control the isolation level is reset to the level in effect when the object was invoked. For example, if you set REPEATABLE READ in a batch, and the batch then calls a stored procedure that sets the isolation level to SERIALIZABLE, the isolation level setting reverts to REPEATABLE READ when the stored procedure returns control to the batch.
For me the easiest way is to use good tool to generate all required classes. Personally I use this site:
It supports quite complex web services and uses ksoap2.
Use [] instead of () as below example.

DataTable data = new DataTable();
DataSet ds = new DataSet();
The solution to my problem which was similar: the libs were invalid. If you look in the .classpath file of the project, you'll see classpathentry tags with the key/value kind="lib". Some of mine were incorrect.
I didn't discover this until I turned off Validation settings. That is, there were so many errors in the JSP files, etc, that the classpath errors weren't evident (or possibly even showing up). As a result, nothing was being compiled into the destination output folders, but no helpful errors on why.
The two calls have different meanings that have nothing to do with performance; the fact that it speeds up the execution time is (or might be) just a side effect. You should understand what each of them does and not blindly include them in every program because they look like an optimization.
ios_base::sync_with_stdio(false);
This disables the synchronization between the C and C++ standard streams. By default, all standard streams are synchronized, which in practice allows you to mix C- and C++-style I/O and get sensible and expected results. If you disable the synchronization, then C++ streams are allowed to have their own independent buffers, which makes mixing C- and C++-style I/O an adventure.
Also keep in mind that synchronized C++ streams are thread-safe (output from different threads may interleave, but you get no data races).
cin.tie(NULL);
This unties cin
from cout
. Tied streams ensure that one stream is flushed automatically before each I/O operation on the other stream.
By default cin
is tied to cout
to ensure a sensible user interaction. For example:
std::cout << "Enter name:";
std::cin >> name;
If cin
and cout
are tied, you can expect the output to be flushed (i.e., visible on the console) before the program prompts input from the user. If you untie the streams, the program might block waiting for the user to enter their name but the "Enter name" message is not yet visible (because cout
is buffered by default, output is flushed/displayed on the console only on demand or when the buffer is full).
So if you untie cin
from cout
, you must make sure to flush cout
manually every time you want to display something before expecting input on cin
.
In conclusion, know what each of them does, understand the consequences, and then decide if you really want or need the possible side effect of speed improvement.
I think it's perfectly explained in item 25 of Scott Meyers' Effective Modern C++. Here's an excerpt:
The part of the Standard blessing the RVO goes on to say that if the conditions for the RVO are met, but compilers choose not to perform copy elision, the object being returned must be treated as an rvalue. In effect, the Standard requires that when the RVO is permitted, either copy elision takes place or
std::move
is implicitly applied to local objects being returned.
Here, RVO refers to return value optimization, and if the conditions for the RVO are met means returning the local object declared inside the function that you would expect to do the RVO, which is also nicely explained in item 25 of his book by referring to the standard (here the local object includes the temporary objects created by the return statement). The biggest take away from the excerpt is either copy elision takes place or std::move
is implicitly applied to local objects being returned. Scott mentions in item 25 that std::move
is implicitly applied when the compiler choose not to elide the copy and the programmer should not explicitly do so.
In your case, the code is clearly a candidate for RVO as it returns the local object p
and the type of p
is the same as the return type, which results in copy elision. And if the compiler chooses not to elide the copy, for whatever reason, std::move
would've kicked in to line 1

I wrote the following code to convert an image from sdcard to a Base64 encoded string to send as a JSON object.And it works great:
String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
fis = new FileInputStream(imagefile);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);
byte[] b = baos.toByteArray();
encImage = Base64.encodeToString(b, Base64.DEFAULT);
This may not be a technical solution, but it works. (if anyone of your teammate has the same branch in local)
Let's assume your branch name as branch-xxx.

LAST EDIT: after 7 years I'm still getting upvotes for this answer, but I guess this one is now much more accurate.
Sure you can, but you'll need to render the page with something. If you really want to only use php, I suggest you HTMLTOPS, which renders the page and outputs it in a ps file (ghostscript), then, convert it in a .jpg, .png, .pdf.. can be little slower with complex pages (and don't support all the CSS).
Else, you can use wkhtmltopdf to output a html page in pdf, jpg, whatever.. Accept CSS2.0, use the webkit (safari's wrapper) to render the page.. so should be fine. You have to install it on your server, as well..
UPDATE Now, with new HTML5 and JS feature, is also possible to render the page into a canvas object using JavaScript. Here a nice library to do that: Html2Canvas and here is an implementation by the same author to get a feedback like G+. Once you have rendered the dom into the canvas, you can then send to the server via ajax and save it as a jpg.
EDIT: You can use the imagemagick tool for transforming pdf to png. My version of wkhtmltopdf does not support images. E.g. convert html.pdf -append html.png
.
EDIT: This small shell script gives a simple / but working usage example on linux with php5-cli and the tools mentioned above.
EDIT: i noticed now that the wkhtmltopdf team is working on another project: wkhtmltoimage, that gives you the jpg directly

This GitPro page does summarize the consequence of a git submodule update nicely
When you run
git submodule update
, it checks out the specific version of the project, but not within a branch. This is called having a detached head — it means the HEAD file points directly to a commit, not to a symbolic reference.
The issue is that you generally don’t want to work in a detached head environment, because it’s easy to lose changes.
If you do an initial submodule update, commit in that submodule directory without creating a branch to work in, and then run git submodule update again from the superproject without committing in the meantime, Git will overwrite your changes without telling you. Technically you won’t lose the work, but you won’t have a branch pointing to it, so it will be somewhat difficult to retrieve.
Note March 2013:
As mentioned in "git submodule tracking latest", a submodule now (git1.8.2) can track a branch.
# add submodule to track master branch
git submodule add -b master [URL to Git repo];
# update your submodule
git submodule update --remote
# or (with rebase)
git submodule update --rebase --remote
See "git submodule update --remote
vs git pull
".
MindTooth's answer illustrate a manual update (without local configuration):
git submodule -q foreach git pull -q origin master
In both cases, that will change the submodules references (the gitlink, a special entry in the parent repo index), and you will need to add, commit and push said references from the main repo.
Next time you will clone that parent repo, it will populate the submodules to reflect those new SHA1 references.
The rest of this answer details the classic submodule feature (reference to a fixed commit, which is the all point behind the notion of a submodule).
To avoid this issue, create a branch when you work in a submodule directory with git checkout -b work or something equivalent. When you do the submodule update a second time, it will still revert your work, but at least you have a pointer to get back to.
Switching branches with submodules in them can also be tricky. If you create a new branch, add a submodule there, and then switch back to a branch without that submodule, you still have the submodule directory as an untracked directory:
So, to answer your questions:
can I create branches/modifications and use push/pull just like I would in regular repos, or are there things to be cautious about?
You can create a branch and push modifications.
WARNING (from Git Submodule Tutorial): Always publish (push) the submodule change before publishing (push) the change to the superproject that references it. If you forget to publish the submodule change, others won't be able to clone the repository.
how would I advance the submodule referenced commit from say (tagged) 1.0 to 1.1 (even though the head of the original repo is already at 2.0)
The page "Understanding Submodules" can help
Git submodules are implemented using two moving parts:
- the
.gitmodules
file and- a special kind of tree object.
These together triangulate a specific revision of a specific repository which is checked out into a specific location in your project.
From the git submodule page
you cannot modify the contents of the submodule from within the main project
100% correct: you cannot modify a submodule, only refer to one of its commits.
This is why, when you do modify a submodule from within the main project, you:
A submodule enables you to have a component-based approach development, where the main project only refers to specific commits of other components (here "other Git repositories declared as sub-modules").
A submodule is a marker (commit) to another Git repository which is not bound by the main project development cycle: it (the "other" Git repo) can evolves independently.
It is up to the main project to pick from that other repo whatever commit it needs.
However, should you want to, out of convenience, modify one of those submodules directly from your main project, Git allows you to do that, provided you first publish those submodule modifications to its original Git repo, and then commit your main project refering to a new version of said submodule.
But the main idea remains: referencing specific components which:
The list of specific commits you are refering to in your main project defines your configuration (this is what Configuration Management is all about, englobing mere Version Control System)
If a component could really be developed at the same time as your main project (because any modification on the main project would involve modifying the sub-directory, and vice-versa), then it would be a "submodule" no more, but a subtree merge (also presented in the question Transferring legacy code base from cvs to distributed repository), linking the history of the two Git repo together.
Does that help understanding the true nature of Git Submodules?
If you want something more similar to your example try _itot_s. On Microsoft compilers _itot_s points to _itoa_s or _itow_s depending on your Unicode setting:
CString str;
_itot_s( 15, str.GetBufferSetLength( 40 ), 40, 10 );
str.ReleaseBuffer();
it should be slightly faster since it doesn't need to parse an input format.
For example,
package verbose
import (
"fmt"
"testing"
)
func TestPrintSomething(t *testing.T) {
fmt.Println("Say hi")
t.Log("Say bye")
}
go test -v
=== RUN TestPrintSomething
Say hi
--- PASS: TestPrintSomething (0.00 seconds)
v_test.go:10: Say bye
PASS
ok so/v 0.002s
-v Verbose output: log all tests as they are run. Also print all text from Log and Logf calls even if the test succeeds.
func (c *T) Log(args ...interface{})
Log formats its arguments using default formatting, analogous to Println, and records the text in the error log. For tests, the text will be printed only if the test fails or the -test.v flag is set. For benchmarks, the text is always printed to avoid having performance depend on the value of the -test.v flag.
A null
pointer is one that points to nowhere. When you dereference a pointer p
, you say "give me the data at the location stored in "p". When p
is a null
pointer, the location stored in p
is nowhere
, you're saying "give me the data at the location 'nowhere'". Obviously, it can't do this, so it throws a null pointer exception
.
In general, it's because something hasn't been initialized properly.
Late to the game but you can also use the janitor
package. This function will remove columns which are all NA, and can be changed to remove rows that are all NA as well.
df <- janitor::remove_empty(df, which = "cols")
See this CodePen https://codepen.io/ella301/pen/vYLNmVg which I created. I used 3 CSS functions min, max and calc to make sure the left and right paddings are fluid between minimum 20px and maximum 120px.
padding: 20px max(min(120px, calc((100% - 1198px) / 2)), 20px);
Hope it helps!
You may try this way. just use a function to get your object
def get_object(self, id):
try:
return Comment.objects.get(pk=id)
except Comment.DoesNotExist:
return False
This is useful when you have more than one class to append. You can join all classes in array with a space.
const visibility = this.props.showBulkActions ? "show" : ""
<div className={["btn-group pull-right", visibility].join(' ')}>

This can be caused when a dependent library has accidentally bundled an old version of slf4j. In my case, it was tika-0.8. See https://issues.apache.org/jira/browse/TIKA-556
The workaround is exclude the component and then manually depends on the correct, or patched version.
EG.
<dependency>
<groupId>org.apache.tika</groupId>
<artifactId>tika-parsers</artifactId>
<version>0.8</version>
<exclusions>
<exclusion>
<!-- NOTE: Version 4.2 has bundled slf4j -->
<groupId>edu.ucar</groupId>
<artifactId>netcdf</artifactId>
</exclusion>
</exclusions>
</dependency>

<!-- Patched version 4.2-min does not bundle slf4j -->
<groupId>edu.ucar</groupId>
<artifactId>netcdf</artifactId>

I am including this answer in case someone comes to this page for the same reason I did. I just wasted an embarrassing amount of time trying to track the problem down. I was calling:
unset($_SESSION['myVar']);
from a logout script. Then navigating to a page that required login, and the server still thought I was logged in. The problem was that the logout script was not calling:
session_start();
Unsetting a session var DOES NOT WORK unless you start the session first.
is to force checkout a branch
git checkout -f <branch_name>
Force checking out a branch is telling git to drop all changes you've made in the current branch, and checkout out the desired one.
or in case you're checking out a commit
git checkout -f <commit-hash>
"thought that I could change branches without committing. If so, how can I set this up? If not, how do I get out of this problem?"
The answer to that is No, that's literally the philosophy of Git that you keep track of all changes, and that each node (i.e. commit) has to be up-to-date with the latest changes you've made, unless you've made a new commit of course.
Then stash them using
git stash
and then to unstash your changes in the desired branch, use
git stash apply
which will apply you changes but keep them in the stash queue too. If you don't want to keep them in the stash stack, then pop them using
git stash pop
That's the equivalent of apply
and then drop
Everything in python is considered as object so functions are also objects. So you can use this method as well.

EDIT: this solution is now in the original answer too.
The accepted answer is not quite correct. You should not be using the position() function since it is relative to the parent. If you are doing global positioning(in most cases?) you should only add the offset top with the outerheight like so:
var actualBottom = $(selector).offset().top + $(selector).outerHeight(true);

You can still use <hr>
as a horizontal line, and you probably should. In HTML5 it defines a thematic break in content, without making any promises about how it is displayed. The attributes that aren't supported in the HTML5 spec are all related to the tag's appearance. The appearance should be set in CSS, not in the HTML itself.
So use the <hr>
tag without attributes, then style it in CSS to appear the way you want.
You say in a comment you want to get "15.09.2016".
For this, use Date
and DateFormatter
:
let date = Date()
let formatter = DateFormatter()
Give the format you want to the formatter:
formatter.dateFormat = "dd.MM.yyyy"
Get the result string:
let result = formatter.string(from: date)
Set your label:
label.text = result
Result:
15.09.2016
Minor update in @Joran's code.
Using the code below, you can avoid the ambiguity and only get the unique of two columns:
dat <- data.frame(id=c(1,1,3), id2=c(1,1,4) ,somevalue=c("x","y","z"))
dat[row.names(unique(dat[,c("id", "id2")])), c("id", "id2")]
generateNumbers()
expects a parameter and you aren't passing one in!
generateNumbers() also returns after it has set the first random number - seems to be some confusion about what it is trying to do.

EDIT
To avoid this error : The specified type member 'Date' is not supported in LINQ to Entities. Only initializers, entity members, and entity navigation properties are supported.
var _My_ResetSet_Array = _DB
.tbl_MyTable
.Where(x => x.Active == true)
.Select(x => x).ToList();
var filterdata = _My_ResetSet_Array
.Where(x=>DateTime.Compare(x.DateTimeValueColumn.Date, DateTime.Now.Date) <= 0 );
The second line is required because LINQ to Entity is not able to convert date property to sql query. So its better to first fetch the data and then apply the date filter.
EDIT
If you just want to compare the date value of the date time than make use of
DateTime.Date
Property - Gets the date component of this instance.
Code for you
var _My_ResetSet_Array = _DB
.tbl_MyTable
.Where(x => x.Active == true
&& DateTime.Compare(x.DateTimeValueColumn.Date, DateTime.Now.Date) <= 0 )
.Select(x => x);
If its like that then use
DateTime.Compare Method - Compares two instances of DateTime and returns an integer that indicates whether the first instance is earlier than, the same as, or later than the second instance.
Code for you
var _My_ResetSet_Array = _DB
.tbl_MyTable
.Where(x => x.Active == true
&& DateTime.Compare(x.DateTimeValueColumn, DateTime.Now) <= 0 )
.Select(x => x);
Example
DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;
if (result < 0)
relationship = "is earlier than";
else if (result == 0)
relationship = "is the same time as";
else
relationship = "is later than";

When you are using as
syntax, like ParentController as parentCtrl
, to define a controller then to access parent scope variable in child controller use following :
var id = $scope.parentCtrl.id;
Where parentCtrl
is name of parent controller using as
syntax and id
is a variable defined in same controller.
The setting you are looking for is allow_url_fopen
.
You have two ways of getting around it without changing php.ini, one of them is to use fsockopen()

I recommend using cURL over file_get_contents()
anyways, since it was built for this.
FWIW, on Ubuntu 10.04.2 LTS installing the ca-certificates-java and the ca-certificates packages fixed this problem for me.
You can always do something like this:
update mytable t
set SomeColumn = c.ComputedValue
from (select *, 42 as ComputedValue from mytable where id = 1) c
where t.id = c.id
You can now also use with statement inside update
update mytable t
set SomeColumn = c.ComputedValue
from (with abc as (select *, 43 as ComputedValue_new from mytable where id = 1
select *, 42 as ComputedValue, abc.ComputedValue_new from mytable n1
inner join abc on n1.id=abc.id) c
where t.id = c.id

I agree on performing the replace on the SQL side, but using the ISNULL function would be the way I'd go.
SELECT ISNULL(table.MyField, "NA") AS MyField
I usually do as much processing of data on our SQL servers and try to do as little data manipulation in SSRS as possible. This is mainly because my SQL server is considerably more powerful than my SSRS server.
One simple way to check your changes to that file in Tomcat 8 + is to open a browser to: http://localhost:8080/manager/text/list

If you're referring to what happens when you echo something, the single quotes will literally echo what you have between them, while the double quotes will evaluate variables between them and output the value of the variable.
For example, this
#!/bin/sh
MYVAR=sometext
echo "double quotes gives you $MYVAR"
echo 'single quotes gives you $MYVAR'
will give this:
double quotes gives you sometext
single quotes gives you $MYVAR

No need for that much code.
You can do all this stuff without coding so much by using only viewpager
with tablayout
.
Your main Layout:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
<android.support.design.widget.TabLayout
android:id="@+id/tabDots"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabBackground="@drawable/tab_selector"
app:tabGravity="center"
app:tabIndicatorHeight="0dp"/>
</RelativeLayout>
Hook up your UI elements inactivity or fragment as follows:
Java Code:
mImageViewPager = (ViewPager) findViewById(R.id.pager);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabDots);
tabLayout.setupWithViewPager(mImageViewPager, true);
That's it, you are good to go.
You will need to create the following xml resource file in the drawable folder.
tab_indicator_selected.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
android:innerRadius="0dp"
android:shape="ring"
android:thickness="4dp"
android:useLevel="false"
xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/colorAccent"/>
</shape>
tab_indicator_default.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="0dp"
android:shape="oval"
android:thickness="2dp"
android:useLevel="false">
<solid android:color="@android:color/darker_gray"/>
</shape>
tab_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/tab_indicator_selected"
android:state_selected="true"/>
<item android:drawable="@drawable/tab_indicator_default"/>
</selector>
Feeling as lazy as I am? Well, all the above code is converted into a library!
Usage
Add the following in your gradle:
implementation 'com.chabbal:slidingdotsplash:1.0.2'
Add the following to your Activity or Fragment layout.
<com.chabbal.slidingdotsplash.SlidingSplashView
android:id="@+id/splash"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:imageResources="@array/img_id_arr"/>
Create an integer array in strings.xml
e.g.
<integer-array name="img_id_arr">
<item>@drawable/img1</item>
<item>@drawable/img2</item>
<item>@drawable/img3</item>
<item>@drawable/img4</item>
</integer-array>
Done!
Extra in order to listen page changes use addOnPageChangeListener(listener);
Github link.
Just finish it up.
string sqlCommand = "SELECT * FROM TABLE";
string connectionString = "blahblah";
DataSet ds = GetDataSet(sqlCommand, connectionString);
DataSet GetDataSet(string sqlCommand, string connectionString)
{
DataSet ds = new DataSet();
using (SqlCommand cmd = new SqlCommand(
sqlCommand, new SqlConnection(connectionString)))
{
cmd.Connection.Open();
DataTable table = new DataTable();
table.Load(cmd.ExecuteReader());
ds.Tables.Add(table);
}
return ds;
}
As above(Kai) or do the following. Really enums are "Enumerations", what you want to do is have a set, therefore you should really use stl::set
enum AnimalFlags
{
HasClaws = 1,
CanFly =2,
EatsFish = 4,
Endangered = 8
};
int main(void)
{
AnimalFlags seahawk;
//seahawk= CanFly | EatsFish | Endangered;
seahawk= static_cast<AnimalFlags>(CanFly | EatsFish | Endangered);
}
You need to use a group by clause.
SELECT site_id, MAX(ts) as TIME, count(*) group by site_id
Note that another approach is to keep with the 4.0 validation behaviour, but to define your own class that derives from RequestValidator
and set:
<httpRuntime requestValidationType="YourNamespace.YourValidator" />
(where YourNamespace.YourValidator
is well, you should be able to guess...)
This way you keep the advantages of 4.0s behaviour (specifically, that the validation happens earlier in the processing), while also allowing the requests you need to let through, through.
Started a jsFiddle here.
It seems the horizontal alignment works with a text-align : center
. Still trying to get the vertical align to work; might have to use absolute
positioning and something like top: 50%
or a pre-calculated padding
from the top.
With VS 2017, debugging ASP.NET project with Chrome doesn't sign you in with your Google account.
To fix that go to Tools -> Options -> Debugging -> General and turn off the setting Enable JavaScript Debugging for ASP.NET (Chrome and IE).
Use Apache Commons (IO and Lang) for simple/common things like this.
Imports:
import org.apache.commons.io.FileUtils;
import org.apache.commons.lang3.ArrayUtils;
Code:
String contents = FileUtils.readFileToString(new File("path/to/your/file.txt"));
String[] array = ArrayUtils.toArray(contents.split(" "));
Done.
Using Java 8 lambda expression:
editText.setOnFocusChangeListener((v, hasFocus) -> {
if(!hasFocus) {
String value = String.valueOf( editText.getText() );
}
});
Consider the second script. If you import it in another one, the instructions, as at "global level", will be executed.
myObj.name=value
or
myObj['name']=value (Quotes are required)
Both of these are interchangeable.
Edit: I'm guessing you meant myObj[prop] = value
, instead of myObj[name] = value. Second syntax works fine: http://jsfiddle.net/waitinforatrain/dNjvb/1/
Another approach is to use the CommaDelimitedStringCollection class from System.Configuration namespace/assembly. It behaves like a list plus it has an overriden ToString method that returns a comma-separated string.
Pros - More flexible than an array.
Cons - You can't pass a string containing a comma.
CommaDelimitedStringCollection list = new CommaDelimitedStringCollection();
list.AddRange(new string[] { "Huey", "Dewey" });
list.Add("Louie");
//list.Add(",");
string s = list.ToString(); //Huey,Dewey,Louie
Here's the more modern streams approach:
myIntegerSet.stream().filter((it) -> it % 2 != 0).collect(Collectors.toSet())
However, this makes a new set, so memory constraints might be an issue if it's a really huge set.
EDIT: previous version of this answer suggested Apache CollectionUtils but that was before steams came about.

Alternatively if adding extra library such as hamcrest
is not desirable, the logic can be implemented as utility method using junit
dependency only:
public static void assertGreaterThan(int greater, int lesser) {
assertGreaterThan(greater, lesser, null);
}
public static void assertGreaterThan(int greater, int lesser, String message) {
if (greater <= lesser) {
fail((StringUtils.isNotBlank(message) ? message + " ==> " : "") +
"Expected: a value greater than <" + lesser + ">\n" +
"But <" + greater + "> was " + (greater == lesser ? "equal to" : "less than") + " <" + lesser + ">");
}
}
attachedCompanyIDs is one big string, so mysql try to find company in this its cast to integer
when you use where in
so if comapnyid = 1 :
companyID IN ('1,2,3')
this is return true
but if the number 1 is not in the first place
companyID IN ('2,3,1')
its return false
You are not specifying a language or framework, but the following header is used for file downloads:
"Content-Disposition: attachment; filename=abc.csv"
Using the Access-Control-Allow-Origin header to the request won't help you in that case while this header can only be used on the response...
To make it work you should probably add this header to your response.You can also try to add the header crossorigin:true
to your request.
git rm -r --cached .
git add .
Best practice: one form per product is definitely the way to go.
Benefits:
In your specific situation
If you only ever intend to have one form element, in this case a submit
button, one form for all should work just fine.
My recommendation Do one form per product, and change your markup to something like:
<form method="post" action="">
<input type="hidden" name="product_id" value="123">
<button type="submit" name="action" value="add_to_cart">Add to Cart</button>
</form>
This will give you a much cleaner and usable POST
. No parsing. And it will allow you to add more parameters in the future (size, color, quantity, etc).
Note: There's no technical benefit to using
<button>
vs.<input>
, but as a programmer I find it cooler to work withaction=='add_to_cart'
thanaction=='Add to Cart'
. Besides, I hate mixing presentation with logic. If one day you decide that it makes more sense for the button to say "Add" or if you want to use different languages, you could do so freely without having to worry about your back-end code.
You could iterate through an enum by implementing the ForwardIndexType
protocol.
The ForwardIndexType
protocol requires you to define a successor()
function to step through the elements.
enum Rank: Int, ForwardIndexType {
case Ace = 1
case Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten
case Jack, Queen, King
// ... other functions
// Option 1 - Figure it out by hand
func successor() -> Rank {
switch self {
case .Ace:
return .Two
case .Two:
return .Three
// ... etc.
default:
return .King
}
}
// Option 2 - Define an operator!
func successor() -> Rank {
return self + 1
}
}
// NOTE: The operator is defined OUTSIDE the class
func + (left: Rank, right: Int) -> Rank {
// I'm using to/from raw here, but again, you can use a case statement
// or whatever else you can think of
return left == .King ? .King : Rank(rawValue: left.rawValue + right)!
}
Iterating over an open or closed range (..<
or ...
) will internally call the successor()
function which allows you to write this:
// Under the covers, successor(Rank.King) and successor(Rank.Ace) are called to establish limits
for r in Rank.Ace...Rank.King {
// Do something useful
}
You can also get this error with any version of git if the remote branch was created after your last clone/fetch and your local repo doesn't know about it yet. I solved it by doing a git fetch
first which "tells" your local repo about all the remote branches.
git fetch
git checkout test-branch
Even though, the best approach for this situation is set custom CSS styles - an alternative could be:
Width
property and set the percentaje as you see more suitable for your purposes.In my desired scenario, I need set (2) radiobuttons/items as follows:
o Item 1 | o Item 2 |
Example:
<asp:RadioButtonList ID="rbtnLstOptionsGenerateCertif" runat="server"
BackColor="Transparent" BorderColor="Transparent" RepeatDirection="Horizontal"
EnableTheming="False" Width="40%">
<asp:ListItem Text="Item 1" Value="0" />
<asp:ListItem Text="Item 2" Value="1" />
</asp:RadioButtonList>
Rendered result:
<table id="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif" class="chxbx2" border="0" style="background-color:Transparent;border-color:Transparent;width:40%;">
<tbody>
<tr>
<td>
<input id="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif_0" type="radio" name="ctl00$ContentPlaceHolder$rbtnLstOptionsGenerateCertif" value="0" checked="checked">
<label for="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif_0">Item 1</label>
</td>
<td>
<input id="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif_1" type="radio" name="ctl00$ContentPlaceHolder$rbtnLstOptionsGenerateCertif" value="1">
<label for="ctl00_ContentPlaceHolder_rbtnLstOptionsGenerateCertif_1">Item 2</label>
</td>
</tr>
</tbody>
</table>

Check out this question / answer. It's more concise than @Geoff's, and also uses the builtin fputcsv function.
$result = $db_con->query('SELECT * FROM `some_table`');
if (!$result) die('Couldn\'t fetch records');
$num_fields = mysql_num_fields($result);
$headers = array();
for ($i = 0; $i < $num_fields; $i++) {
$headers[] = mysql_field_name($result , $i);
}
$fp = fopen('php://output', 'w');
if ($fp && $result) {
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="export.csv"');
header('Pragma: no-cache');
header('Expires: 0');
fputcsv($fp, $headers);
while ($row = $result->fetch_array(MYSQLI_NUM)) {
fputcsv($fp, array_values($row));
}
die;
}
The only option to actuall have this made pixel perfect is to create some transparent padding within the GIF itself. That way you can actually align it to the right of the LI and still have the background padding you are looking for.
Following worked for me..
for a table say, 'test_update_cmd', source value column col2, target value column col1 and condition column col3: -
UPDATE test_update_cmd SET col1=col2 WHERE col3='value';
Good Luck!
Just do nothing once the criteria is met, otherwise do the processing you require and the For
loop will go to the next item.
For i = 2 To 24
Level = Cells(i, 4)
Return = Cells(i, 5)
If Return = 0 And Level = 0 Then
'Do nothing
Else
'Do something

Or change the clause so it only processes if the conditions are met:
For i = 2 To 24
Level = Cells(i, 4)
Return = Cells(i, 5)
If Return <> 0 Or Level <> 0 Then
'Do something

instead of files use pipes and if u wana use C and not C++ u can use popen like this
#include<stdlib.h>
#include<stdio.h>
FILE *fp= popen("date +F","r");
and use *fp as a normal file pointer with fgets and all
if u wana use c++ strings, fork a child, invoke the command and then pipe it to the parent.
#include <stdlib.h>
#include <iostream>
#include <string>
using namespace std;
string currentday;
int dependPipe[2];
pipe(dependPipe);// make the pipe
if(fork()){//parent
dup2(dependPipe[0],0);//convert parent's std input to pipe's output
close(dependPipe[1]);
getline(cin,currentday);
} else {//child
dup2(dependPipe[1],1);//convert child's std output to pipe's input
close(dependPipe[0]);
system("date +%F");
}
// make a similar 1 for date +T but really i recommend u stick with stuff in time.h GL
student_user = User.objects.get(id=user_id)
available_subjects = Subject.objects.exclude(subject_grade__student__user=student_user) # My ans
enrolled_subjects = SubjectGrade.objects.filter(student__user=student_user)
context.update({'available_subjects': available_subjects, 'student_user': student_user,
'request':request, 'enrolled_subjects': enrolled_subjects})
In my application above, i assume that once a student is enrolled, a subject SubjectGrade instance will be created that contains the subject enrolled and the student himself/herself.
Subject and Student User model is a Foreign Key to the SubjectGrade Model.
In "available_subjects", i excluded all the subjects that are already enrolled by the current student_user by checking all subjectgrade instance that has "student" attribute as the current student_user
PS. Apologies in Advance if you can't still understand because of my explanation. This is the best explanation i Can Provide. Thank you so much
Search for LISTEN directive in the apache config files (httpd.conf, apache2.conf, listen.conf,...) and if you see localhost, or 127.0.0.1, then you need to overwrite with your public ip.
Short and universal approach
If you want to check any array if it has falsy values (like false, undefined, null or empty strings) you can just use every() method like this:
array.every(function(element) {return !!element;}); // returns true or false
For example:
['23', null, 2, {key: 'value'}].every(function(element) {return !!element;}); // returns false
['23', '', 2, {key: 'value'}].every(function(element) {return !!element;}); // returns false
['23', true, 2, {key: 'value'}].every(function(element) {return !!element;}); // returns true
If you need to get a first index of falsy value, you can do it like this:
let falsyIndex;
if(!['23', true, 2, null, {key: 'value'}].every(function(element, index) {falsyIndex = index; return !!element;})) {
console.log(falsyIndex);
} // logs 3
If you just need to check a falsy value of an array for a given index you can just do it like this:
if (!!array[index]) {
// array[index] is a correct value
}
else {
// array[index] is a falsy value
}
You can Trigger a Share Dialog using the FB.ui function with the share method parameter to share a link. This dialog is available in the Facebook SDKs for JavaScript, iOS, and Android by performing a full redirect to a URL.
You can trigger this call:
FB.ui({
method: 'share',
href: 'https://developers.facebook.com/docs/', // Link to share
}, function(response){});
You can also include open graph meta tags on the page at this URL to customise the story that is shared back to Facebook.
Note that response.error_message will appear only if someone using your app has authenticated your app with Facebook Login.
Also you can directly share link with call by having Javascript Facebook SDK.
https://www.facebook.com/dialog/share&app_id=145634995501895&display=popup&href=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2F&redirect_uri=https%3A%2F%2Fdevelopers.facebook.com%2Ftools%2Fexplorer
https://www.facebook.com/dialog/share&app_id={APP_ID}&display=popup&href={LINK_TO_SHARE}&redirect_uri={REDIRECT_AFTER_SHARE}
app_id => Your app's unique identifier. (Required.)
redirect_uri => The URL to redirect to after a person clicks a button on the dialog. Required when using URL redirection.
display => Determines how the dialog is rendered.
If you are using the URL redirect dialog implementation, then this will be a full page display, shown within Facebook.com. This display type is called page. If you are using one of our iOS or Android SDKs to invoke the dialog, this is automatically specified and chooses an appropriate display type for the device. If you are using the Facebook SDK for JavaScript, this will default to a modal iframe type for people logged into your app or async when using within a game on Facebook.com, and a popup window for everyone else. You can also force the popup or page types when using the Facebook SDK for JavaScript, if necessary. Mobile web apps will always default to the touch display type. share Parameters
I've posted here some methods to convert interval to nanoseconds and nanoseconds to interval. These methods have a nanosecond precision.
You just need to adjust it to get milliseconds instead of nanoseconds.

New answer (2016-04-20)
Using Spring Boot 1.3.1.RELEASE
New Step 1 - It is easy and less intrusive to add the following properties to the application.properties:
spring.mvc.throw-exception-if-no-handler-found=true
spring.resources.add-mappings=false
Much easier than modifying the existing DispatcherServlet instance (as below)! - JO'
If working with a full RESTful Application, it is very important to disable the automatic mapping of static resources since if you are using Spring Boot's default configuration for handling static resources then the resource handler will be handling the request (it's ordered last and mapped to /** which means that it picks up any requests that haven't been handled by any other handler in the application) so the dispatcher servlet doesn't get a chance to throw an exception.
New Answer (2015-12-04)
Using Spring Boot 1.2.7.RELEASE
New Step 1 - I found a much less intrusive way of setting the "throExceptionIfNoHandlerFound" flag. Replace the DispatcherServlet replacement code below (Step 1) with this in your application initialization class:
@ComponentScan()
@EnableAutoConfiguration
public class MyApplication extends SpringBootServletInitializer {
private static Logger LOG = LoggerFactory.getLogger(MyApplication.class);
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(MyApplication.class, args);
DispatcherServlet dispatcherServlet = (DispatcherServlet)ctx.getBean("dispatcherServlet");
dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);
}
In this case, we're setting the flag on the existing DispatcherServlet, which preserves any auto-configuration by the Spring Boot framework.
One more thing I've found - the @EnableWebMvc annotation is deadly to Spring Boot. Yes, that annotation enables things like being able to catch all the controller exceptions as described below, but it also kills a LOT of the helpful auto-configuration that Spring Boot would normally provide. Use that annotation with extreme caution when you use Spring Boot.
Original Answer:
After a lot more research and following up on the solutions posted here (thanks for the help!) and no small amount of runtime tracing into the Spring code, I finally found a configuration that will handle all Exceptions (not Errors, but read on) including 404s.
Step 1 - tell SpringBoot to stop using MVC for "handler not found" situations. We want Spring to throw an exception instead of returning to the client a view redirect to "/error". To do this, you need to have an entry in one of your configuration classes:
// NEW CODE ABOVE REPLACES THIS! (2015-12-04)
@Configuration
public class MyAppConfig {
@Bean // Magic entry
public DispatcherServlet dispatcherServlet() {
DispatcherServlet ds = new DispatcherServlet();
ds.setThrowExceptionIfNoHandlerFound(true);
return ds;
}
}
The downside of this is that it replaces the default dispatcher servlet. This hasn't been a problem for us yet, with no side effects or execution problems showing up. If you're going to do anything else with the dispatcher servlet for other reasons, this is the place to do them.
Step 2 - Now that spring boot will throw an exception when no handler is found, that exception can be handled with any others in a unified exception handler:
@EnableWebMvc
@ControllerAdvice
public class ServiceExceptionHandler extends ResponseEntityExceptionHandler {
@ExceptionHandler(Throwable.class)
@ResponseBody
ResponseEntity<Object> handleControllerException(HttpServletRequest req, Throwable ex) {
ErrorResponse errorResponse = new ErrorResponse(ex);
if(ex instanceof ServiceException) {
errorResponse.setDetails(((ServiceException)ex).getDetails());
}
if(ex instanceof ServiceHttpException) {
return new ResponseEntity<Object>(errorResponse,((ServiceHttpException)ex).getStatus());
} else {
return new ResponseEntity<Object>(errorResponse,HttpStatus.INTERNAL_SERVER_ERROR);
}
}
@Override
protected ResponseEntity<Object> handleNoHandlerFoundException(NoHandlerFoundException ex, HttpHeaders headers, HttpStatus status, WebRequest request) {
Map<String,String> responseBody = new HashMap<>();
responseBody.put("path",request.getContextPath());
responseBody.put("message","The URL you have reached is not in service at this time (404).");
return new ResponseEntity<Object>(responseBody,HttpStatus.NOT_FOUND);
}
...
}
Keep in mind that I think the "@EnableWebMvc" annotation is significant here. It seems that none of this works without it. And that's it - your Spring boot app will now catch all exceptions, including 404s, in the above handler class and you may do with them as you please.
One last point - there doesn't seem to be a way to get this to catch thrown Errors. I have a wacky idea of using aspects to catch errors and turn them into Exceptions that the above code can then deal with, but I have not yet had time to actually try implementing that. Hope this helps someone.
Any comments/corrections/enhancements will be appreciated.
Just create a new array in your dictionary
Dictionary<string, List<string>> myDic = new Dictionary<string, List<string>>();
myDic.Add(newKey, new List<string>(existingList));
NOTE:
The mentioned LATEST
and RELEASE
metaversions have been dropped for plugin dependencies in Maven 3 "for the sake of reproducible builds", over 6 years ago.
(They still work perfectly fine for regular dependencies.)
For plugin dependencies please refer to this Maven 3 compliant solution.
If you always want to use the newest version, Maven has two keywords you can use as an alternative to version ranges. You should use these options with care as you are no longer in control of the plugins/dependencies you are using.
When you depend on a plugin or a dependency, you can use the a version value of LATEST or RELEASE. LATEST refers to the latest released or snapshot version of a particular artifact, the most recently deployed artifact in a particular repository. RELEASE refers to the last non-snapshot release in the repository. In general, it is not a best practice to design software which depends on a non-specific version of an artifact. If you are developing software, you might want to use RELEASE or LATEST as a convenience so that you don't have to update version numbers when a new release of a third-party library is released. When you release software, you should always make sure that your project depends on specific versions to reduce the chances of your build or your project being affected by a software release not under your control. Use LATEST and RELEASE with caution, if at all.
See the POM Syntax section of the Maven book for more details. Or see this doc on Dependency Version Ranges, where:
[
& ]
) means "closed" (inclusive).(
& )
) means "open" (exclusive).Here's an example illustrating the various options. In the Maven repository, com.foo:my-foo has the following metadata:
<?xml version="1.0" encoding="UTF-8"?><metadata>
<groupId>com.foo</groupId>
<artifactId>my-foo</artifactId>
<version>2.0.0</version>
<versioning>
<release>1.1.1</release>
<versions>
<version>1.0</version>
<version>1.0.1</version>
<version>1.1</version>
<version>1.1.1</version>
<version>2.0.0</version>
</versions>
<lastUpdated>20090722140000</lastUpdated>
</versioning>
</metadata>
If a dependency on that artifact is required, you have the following options (other version ranges can be specified of course, just showing the relevant ones here):
Declare an exact version (will always resolve to 1.0.1):
<version>[1.0.1]</version>
Declare an explicit version (will always resolve to 1.0.1 unless a collision occurs, when Maven will select a matching version):
<version>1.0.1</version>
Declare a version range for all 1.x (will currently resolve to 1.1.1):
<version>[1.0.0,2.0.0)</version>
Declare an open-ended version range (will resolve to 2.0.0):
<version>[1.0.0,)</version>
Declare the version as LATEST (will resolve to 2.0.0) (removed from maven 3.x)
<version>LATEST</version>
Declare the version as RELEASE (will resolve to 1.1.1) (removed from maven 3.x):
<version>RELEASE</version>
Note that by default your own deployments will update the "latest" entry in the Maven metadata, but to update the "release" entry, you need to activate the "release-profile" from the Maven super POM. You can do this with either "-Prelease-profile" or "-DperformRelease=true"
It's worth emphasising that any approach that allows Maven to pick the dependency versions (LATEST, RELEASE, and version ranges) can leave you open to build time issues, as later versions can have different behaviour (for example the dependency plugin has previously switched a default value from true to false, with confusing results).
It is therefore generally a good idea to define exact versions in releases. As Tim's answer points out, the maven-versions-plugin is a handy tool for updating dependency versions, particularly the versions:use-latest-versions and versions:use-latest-releases goals.
You should do mkdir build

IMHO, the best way to use two different Python versions on macOS is via homebrew
. After installing homebrew on macOS, run the commands below on your terminal.
brew install python@2
brew install python
Now you can run Python 2.7 by invoking python2
or Python 3 by invoking python3
. In addition to this, you can use virtualenv
or pyenv to manage different versions of python
environments.
I have never personally used miniconda
but from the documentation, it looks like it is similar to using pip
and virtualenv
in combination.
The isinstance
built-in is the preferred way if you really must, but even better is to remember Python's motto: "it's easier to ask forgiveness than permission"!-) (It was actually Grace Murray Hopper's favorite motto;-). I.e.:
def my_print(text, begin, end):
"Print 'text' in UPPER between 'begin' and 'end' in lower"
try:
print begin.lower() + text.upper() + end.lower()
except (AttributeError, TypeError):
raise AssertionError('Input variables should be strings')
This, BTW, lets the function work just fine on Unicode strings -- without any extra effort!-)

Authentication issue: I use TortoiseGit GUI tool, I need to tell tortoise the username and password so that it can access to work with Git/GitHub/Gitlab code base. To tell it, rt click inside any folder to get TortoiseGit menu.

You will be prompted for password and then it worked.
parentElement
is new to Firefox 9 and to DOM4, but it has been present in all other major browsers for ages.
In most cases, it is the same as parentNode
. The only difference comes when a node's parentNode
is not an element. If so, parentElement
is null
.
As an example:
document.body.parentNode; // the <html> element
document.body.parentElement; // the <html> element
document.documentElement.parentNode; // the document node
document.documentElement.parentElement; // null
(document.documentElement.parentNode === document); // true
(document.documentElement.parentElement === document); // false
Since the <html>
element (document.documentElement
) doesn't have a parent that is an element, parentElement
is null
. (There are other, more unlikely, cases where parentElement
could be null
, but you'll probably never come across them.)
You have to set to element_blank()
in theme()
elements you need to remove
ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut))+
theme(axis.title.x=element_blank(),
axis.text.x=element_blank(),
axis.ticks.x=element_blank())

I don't think one syntax has real value over another. It all boils down, like you mentionned, to uniformity across the source files.
The only point where I find such rules interesting is when I need 2 things named identicaly, for example :
void myFunc(int index){
this->index = index;
}
void myFunc(int index){
m_index = index;
}
I use it to differentiate the two. Also when I wrap calls, like from windows Dll, RecvPacket(...) from the Dll might be wrapped in RecvPacket(...) in my code. In these particular occasions using a prefix like "_" might make the two look alike, easy to identify which is which, but different for the compiler
After reading all of this, I might just embed a hyperlink in the email body like this:
To reply to this email, click here <a href="mailto:...">[email protected]</a>
I changed Scanner fin = new Scanner(file);
to Scanner fin = new Scanner(new File(file));
and it works perfectly now. I didn't think the difference mattered but there you go.
You can set Apache to serve pages from anywhere with any restrictions but it's normally distributed in a more secure form.
Editing your apache files (http.conf is one of the more common names) will allow you to set any folder so it appears in your webroot.
EDIT:
alias myapp c:\myapp\
I've edited my answer to include the format for creating an alias in the http.conf file which is sort of like a shortcut in windows or a symlink under un*x where Apache 'pretends' a folder is in the webroot. This is probably going to be more useful to you in the long term.

You can also pull the latest commit and just undo until the commit you desire:
git pull origin master
git reset --hard HEAD~1
Replace master
with your desired branch.
Use git log to see to which commit you would like to revert:
git log
Personally, this has worked for me better.
Basically, what this does is pulls the latest commit, and you manually revert commits one by one. Use git log in order to see commit history.
Good points: Works as advertised. You don't have to use commit hash or pull unneeded branches.
Bad points: You need to revert commits on by one.
WARNING: Commit/stash all your local changes, because with --hard
you are going to lose them. Use at your own risk!
You can use extensions for this.
extension NSDate {
//NSString to NSDate
convenience
init(dateString:String) {
let nsDateFormatter = NSDateFormatter()
nsDateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
// Add the locale if required here
let dateObj = nsDateFormatter.dateFromString(dateString)
self.init(timeInterval:0, sinceDate:dateObj!)
}
//NSDate to time string
func getTime() -> String {
let timeFormatter = NSDateFormatter()
timeFormatter.dateFormat = "hh:mm"
//Can also set the default styles for date or time using .timeStyle or .dateStyle
return timeFormatter.stringFromDate(self)
}
//NSDate to date string
func getDate() -> String {
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd, MMM"
return dateFormatter.stringFromDate(self)
}
//NSDate to String
func getString() -> String {
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
return dateFormatter.stringFromDate(self)
}
}
So while execution actual code will look like follows
var dateObjFromString = NSDate(dateString: cutDateTime)
var dateString = dateObjFromString.getDate()
var timeString = dateObjFromString.getTime()
var stringFromDate = dateObjFromString.getString()
There are some defaults methods as well but I guess it might not work for the format you have given from documentation
-dateFromString(_:)
-stringFromDate(_:)
-localizedStringFromDate(_ date: NSDate,
dateStyle dateStyle: NSDateFormatterStyle,
timeStyle timeStyle: NSDateFormatterStyle) -> String
Try to use Catalano Framework.
Keypoints:
The Catalano Framework is a framework for scientific computing for Java and Android. The project started as an initial port of the many features of the AForge.NET and Accord.NET frameworks for .NET, but is steadily growing with more advanced features which are now being shared between those projects.
Example:
FastBitmap fb = new FastBitmap(bitmap);
Grayscale g = new Grayscale();
g.applyInPlace(fb);
Threshold t = new Threshold(120);
t.applyInPlace(fb);
bitmap = fb.toBitmap();
//Show the result

Long.MIN_VALUE.
Let's say for instance you want to get a list of all your customers:
var customers = context.Customers.ToList();
And let's assume that each Customer
object has a reference to its set of Orders
, and that each Order
has references to LineItems
which may also reference a Product
.
As you can see, selecting a top-level object with many related entities could result in a query that needs to pull in data from many sources. As a performance measure, Include()
allows you to indicate which related entities should be read from the database as part of the same query.
Using the same example, this might bring in all of the related order headers, but none of the other records:
var customersWithOrderDetail = context.Customers.Include("Orders").ToList();
As a final point since you asked for SQL, the first statement without Include()
could generate a simple statement:
SELECT * FROM Customers;
The final statement which calls Include("Orders")
may look like this:
SELECT *
FROM Customers JOIN Orders ON Customers.Id = Orders.CustomerId;
You don't need to escape the '
character in a String (wrapped in "
), and you don't have to escape a "
character in a char (wrapped in '
).

You can force a line break in outlook when attaching one (or two?) tab characters (\t) just before the line break (CRLF).
Example:
This is my heading in the mail\t\n
Just here Outlook is forced to begin a new line.
It seems to work on Outlook 2010. Please test if this works on other versions.

How about Application.EnableCancelKey - Use the Esc button
On Error GoTo handleCancel
Application.EnableCancelKey = xlErrorHandler
MsgBox "This may take a long time: press ESC to cancel"
For x = 1 To 1000000 ' Do something 1,000,000 times (long!)
' do something here
Next x
handleCancel:
If Err = 18 Then
MsgBox "You cancelled"
End If

I have to plug EasyGit here, which is a wrapper to make git more approachable to novices without confusing seasoned users. One of the things it does is give more meanings to git revert
. In this case, you would simply say:
eg revert foo/bar foo/baz
Maybe you want set -e
:
www.davidpashley.com/articles/writing-robust-shell-scripts.html#id2382181:
This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.
Or you could use your solo cases as intended and use your default case to specify range instructions as :
switch(n) {
case 1 : System.out.println("case 1"); break;
case 4 : System.out.println("case 4"); break;
case 99 : System.out.println("case 99"); break;
default :
if (n >= 10 && n <= 15)
System.out.println("10-15 range");
else if (n >= 100 && n <= 200)
System.out.println("100-200 range");
else
System.out.println("Your default case");
break;
}
if tableFields
is an array , you can loop through elements as following :
for (item in tableFields); {
console.log(tableFields[item]);
}
by the way i saw a logical error in you'r code.just remove ;
from end of for loop
right here :
for (item in tableFields); {
.
this will cause you'r loop to do just nothing.and the following line will be executed only once :
// Do stuff
If you have a 64-bit OS, instead of i686, you have x86_64
or ia64
in the output of uname -a
. In that you do not have any of these two strings; you have a 32-bit OS (note that this does not mean that your CPU is not 64-bit).
Decode to Unicode, encode the results to UTF8.
apple.decode('latin1').encode('utf8')

df = pd.DataFrame([(1, 2, 3, 4),
(5, 6, 7, 8),
(9, 0, 1, 2),
(3, 4, 5, 6)],
columns=list('abcd'),
index=['India', 'France', 'England', 'Germany'])
print(df)
gives
a b c d
India 1 2 3 4
France 5 6 7 8
England 9 0 1 2
Germany 3 4 5 6
Try to using application/* instead. And use JSON.maybeJson() to check the data structure in the controller.
GROUP BY col1, col2, col3
in jQuery
you might target the Parent directly.
THIS IS USEFUL IF YOU DO NOT KNOW EXACTLY HOW MANY CHILDREN WILL BE ADDED DYNAMICALLY or IF YOU JUST CAN'T FIGURE OUT THEIR NUMBER.
var tWidth=0;
$('.children').each(function(i,e){
tWidth += $(e).width();
///Example: If the Children have a padding-left of 10px;..
//You could do instead:
tWidth += ($(e).width()+10);
})
$('#parent').css('width',tWidth);
This will let the parent
grow horizontally as the children
are beng added.
NOTE: This assumes that the '.children'
have a width
and Height
Set
Hope that Helps.
To expand a little on other answers here, and help explain a lot of the example code you'll see dotted about, most of the time you don't read and write to a stream directly. Streams are a low-level means to transfer data.
You'll notice that the functions for reading and writing are all byte orientated, e.g. WriteByte(). There are no functions for dealing with integers, strings etc. This makes the stream very general-purpose, but less simple to work with if, say, you just want to transfer text.
However, .NET provides classes that convert between native types and the low-level stream interface, and transfers the data to or from the stream for you. Some notable such classes are:
StreamWriter // Badly named. Should be TextWriter.
StreamReader // Badly named. Should be TextReader.
BinaryWriter
BinaryReader
To use these, first you acquire your stream, then you create one of the above classes and associate it with the stream. E.g.
MemoryStream memoryStream = new MemoryStream();
StreamWriter myStreamWriter = new StreamWriter(memoryStream);
StreamReader and StreamWriter convert between native types and their string representations then transfer the strings to and from the stream as bytes. So
myStreamWriter.Write(123);
will write "123" (three characters '1', '2' then '3') to the stream. If you're dealing with text files (e.g. html), StreamReader and StreamWriter are the classes you would use.
Whereas
myBinaryWriter.Write(123);
will write four bytes representing the 32-bit integer value 123 (0x7B, 0x00, 0x00, 0x00). If you're dealing with binary files or network protocols BinaryReader and BinaryWriter are what you might use. (If you're exchanging data with networks or other systems, you need to be mindful of endianness, but that's another post.)
You should never use an exception if you don't have to - the overhead is horrible.
The variations on TryParse solve the problem - if you want to get creative (to make your code look more elegant) you could probably do something with an extension method in 3.5 but the code would be more or less the same.

You can't update two tables at once, but you can link an update into an insert using OUTPUT INTO
, and you can use this output as a join for the second update:
DECLARE @ids TABLE (id int);
BEGIN TRANSACTION
UPDATE Table1
SET Table1.LastName = 'DR. XXXXXX'
OUTPUT INSERTED.id INTO @ids
WHERE Table1.field = '010008';
UPDATE Table2
SET Table2.WAprrs = 'start,stop'
FROM Table2
JOIN @ids i on i.id = Table2.id;
COMMIT;
I changed your example WHERE
condition to be some other field than id
. If it's id
the you don't need this fancy OUTPUT
, you can just UPDATE
the second table for the same id='010008'
.
The following code is the best line(s) of code I use that will create the directory if not present.
System.IO.Directory.CreateDirectory(HttpContext.Current.Server.MapPath("~/temp/"));
If the directory already exists, this method does not create a new directory, but it returns a DirectoryInfo object for the existing directory. >
If you're only interested in seeing the currently deleted files, you can use this:
git ls-files --deleted
if you then want to remove them (in case you deleted them not using "git rm") pipe that result to xargs git rm
git ls-files --deleted | xargs git rm
I had this recently after refactoring in a new connection manager. A new routine accepted a transaction so it could be run as part of a batch, problem was with a using block:
public IEnumerable<T> Query<T>(IDbTransaction transaction, string command, dynamic param = null)
{
using (transaction.Connection)
{
using (transaction)
{
return transaction.Connection.Query<T>(command, new DynamicParameters(param), transaction, commandType: CommandType.StoredProcedure);
}
}
}
It looks as though the outer using was closing the underlying connection thus any attempts to commit or rollback the transaction threw up the message "This SqlTransaction has completed; it is no longer usable."
I removed the usings added a covering test and the problem went away.
public IEnumerable<T> Query<T>(IDbTransaction transaction, string command, dynamic param = null)
{
return transaction.Connection.Query<T>(command, new DynamicParameters(param), transaction, commandType: CommandType.StoredProcedure);
}
Check for anything that might be closing the connection while inside the context of a transaction.
Just ran into this... I have a common library shared among multiple transpiled products. I was using symlinks with brunch to handle sharing things between the projects. When moving to webpack, this stopped working.
What did get things working was using webpack configuration to turn off symlink resolving.
i.e. adding this in webpack.config.js
:
module.exports = {
//...
resolve: {
symlinks: false
}
};
as documented here:
https://webpack.js.org/configuration/resolve/#resolvesymlinks
You need a ResourceLink in your META-INF/context.xml
file to make the global resource available to the web application.
<ResourceLink name="jdbc/mydb"
global="jdbc/mydb"
type="javax.sql.DataSource" />
I ran into this problem recently and solved it a different way. If you are running MySQL version 5.6.20 there is a known bug in the system. See MySQL docs
Important Due to Bug #69477, redo log writes for large, externally stored BLOB fields could overwrite the most recent checkpoint. To address this bug, a patch introduced in MySQL 5.6.20 limits the size of redo log BLOB writes to 10% of the redo log file size. As a result of this limit, innodb_log_file_size should be set to a value greater than 10 times the largest BLOB data size found in the rows of your tables plus the length of other variable length fields (VARCHAR, VARBINARY, and TEXT type fields).
In my situation the offending blob table was around 16MB. Thus, the way I solved it was by adding a line to my.cnf that ensured I had at least 10x that amount and then some:
innodb_log_file_size = 256M
I encountered another problem that returns the same error.
I used a json string with single quotes :
{
'property': 1
}
But json.loads
accepts only double quotes for json properties :
{
"property": 1
}
json.loads
doesn't accept a final comma:
{
"property": "text",
"property2": "text2",
}
ast
to solve single quote and final comma issuesYou can use ast
(part of standard library for both Python 2 and 3) for this processing. Here is an example :
import ast
# ast.literal_eval() return a dict object, we must use json.dumps to get JSON string
import json
# Single quote to double with ast.literal_eval()
json_data = "{'property': 'text'}"
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property": "text"}
# ast.literal_eval() with double quotes
json_data = '{"property": "text"}'
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property": "text"}
# ast.literal_eval() with final coma
json_data = "{'property': 'text', 'property2': 'text2',}"
json_data = ast.literal_eval(json_data)
print(json.dumps(json_data))
# Displays : {"property2": "text2", "property": "text"}
Using ast
will prevent you from single quote and final comma issues by interpet the JSON like Python dictionnary (so you must follow the Python dictionnary syntax). It's a pretty good and safely alternative of eval()
function for literal structures.
Python documentation warned us of using large/complex string :
Warning It is possible to crash the Python interpreter with a sufficiently large/complex string due to stack depth limitations in Python’s AST compiler.
To use json.dumps
with single quotes easily you can use this code:
import ast
import json
data = json.dumps(ast.literal_eval(json_data_single_quote))
ast
documentationIf you frequently edit JSON, you may use CodeBeautify. It helps you to fix syntax error and minify/beautify JSON.
I hope it helps.
apply this code for get the ipaddress:
if (getenv('HTTP_X_FORWARDED_FOR')) { $pipaddress = getenv('HTTP_X_FORWARDED_FOR');
$ipaddress = getenv('REMOTE_ADDR');
echo "Your Proxy IP address is : ".$pipaddress. "(via $ipaddress)" ; }
else { $ipaddress = getenv('REMOTE_ADDR'); echo "Your IP address is : $ipaddress"; }

Here's how you'd roll your own function http://play.golang.org/p/Qgw7XuLNhb
func compare(a, b T) bool {
if &a == &b {
return true
}
if a.X != b.X || a.Y != b.Y {
return false
}
if len(a.Z) != len(b.Z) || len(a.M) != len(b.M) {
return false
}
for i, v := range a.Z {
if b.Z[i] != v {
return false
}
}
for k, v := range a.M {
if b.M[k] != v {
return false
}
}
return true
}
If the row contains some leading (or trailing) th
tags before the td
you should use the :first-of-type
and the :last-of-type
selectors. Otherwise the first td
won't be selected if it's not the first element of the row.
This gives:
td:first-of-type, td:last-of-type {
/* styles */
}
