As a late corolloary to the earlier answers here, you probably end up in situations where you want some but not all variables to be interpolated. You can solve that by using backslashes to escape dollar signs and backticks; or you can put the static text in a variable.
Name='Rich Ba$tard'
dough='$$$dollars$$$'
cat <<____HERE
$Name, you can win a lot of $dough this week!
Notice that \`backticks' need escaping if you want
literal text, not `pwd`, just like in variables like
\$HOME (current value: $HOME)
____HERE
Demo: https://ideone.com/rMF2XA
Note that any of the quoting mechanisms -- \____HERE
or "____HERE"
or '____HERE'
-- will disable all variable interpolation, and turn the here-document into a piece of literal text.
A common task is to combine local variables with script which should be evaluated by a different shell, programming language, or remote host.
local=$(uname)
ssh -t remote <<:
echo "$local is the value from the host which ran the ssh command"
# Prevent here doc from expanding locally; remote won't see backslash
remote=\$(uname)
# Same here
echo "\$remote is the value from the host we ssh:ed to"

I don't know if I would say heredoc is laziness. One can say that doing anything is laziness, as there are always more cumbersome ways to do anything.
For example, in certain situations you may want to output text, with embedded variables without having to fetch from a file and run a template replace. Heredoc allows you to forgo having to escape quotes, so the text you see is the text you output. Clearly there are some negatives, for example, you can't indent your heredoc, and that can get frustrating in certain situation, especially if your a stickler for unified syntax, which I am.
You can use +=
to concatenate your string, seems like no one answered that, which will be readable, and also neat... something like this
var hello = 'hello' +
'world' +
'blah';
can be also written as
var hello = 'hello';
hello += ' world';
hello += ' blah';
console.log(hello);
For future people who may have this issue the following format worked:
(cat <<- _EOF_
LogFile /var/log/clamd.log
LogTime yes
DatabaseDirectory /var/lib/clamav
LocalSocket /tmp/clamd.socket
TCPAddr 127.0.0.1
SelfCheck 1020
ScanPDF yes
_EOF_
) > /etc/clamd.conf
The EOF
token must be at the beginning of the line, you can't indent it along with the block of code it goes with.
If you write <<-EOF
you may indent it, but it must be indented with Tab characters, not spaces. So it still might not end up even with the block of code.
Also make sure you have no whitespace after the EOF
token on the line.
this style can be used in makefiles too (and in fact it is used quite often).
python - <<EOF
import sys
for r in range(3): print 'rob'
EOF
or
python - <<-EOF
import sys
for r in range(3): print 'rob'
EOF
in latter case leading tab characters are removed too (and some structured outlook can be achieved)
instead of EOF can stand any marker word not appearing in the here document at a beginning of a line (see also here documents in the bash manpage or here).
This should work, I just tested it out and it worked as expected: no expansion, substitution, or what-have-you took place.
cat <<< '
#!/bin/bash
curr=`cat /sys/class/backlight/intel_backlight/actual_brightness`
if [ $curr -lt 4477 ]; then
curr=$((curr+406));
echo $curr > /sys/class/backlight/intel_backlight/brightness;
fi' > file # use overwrite mode so that you don't keep on appending the same script to that file over and over again, unless that's what you want.
Using the following also works.
cat <<< ' > file
... code ...'
Also, it's worth noting that when using heredocs, such as << EOF
, substitution and variable expansion and the like takes place. So doing something like this:
cat << EOF > file
cd "$HOME"
echo "$PWD" # echo the current path
EOF
will always result in the expansion of the variables $HOME
and $PWD
. So if your home directory is /home/foobar
and the current path is /home/foobar/bin
, file
will look like this:
cd "/home/foobar"
echo "/home/foobar/bin"
instead of the expected:
cd "$HOME"
echo "$PWD"
This is called heredoc format to provide a string into stdin. See https://en.wikipedia.org/wiki/Here_document#Unix_shells for more details.
From man bash
:
Here Documents
This type of redirection instructs the shell to read input from the current source until a line containing only word (with no trailing blanks) is seen.
All of the lines read up to that point are then used as the standard input for a command.
The format of here-documents is:
<<[-]word here-document delimiter
No parameter expansion, command substitution, arithmetic expansion, or pathname expansion is performed on word. If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded. If word is unquoted, all lines of the here-document are subjected to parameter expansion, command substitution, and arithmetic expansion. In the latter case, the character sequence
\<newline>
is ignored, and\
must be used to quote the characters\
,$
, and`
.If the redirection operator is
<<-
, then all leading tab characters are stripped from input lines and the line containing delimiter. This allows here-documents within shell scripts to be indented in a natural fashion.
Thanks to dimo414's answer, this shows how his great solution works, and shows that you can have quotes and variables in the text easily as well:
$ ./test.sh
The text from the example function is:
Welcome dev: Would you "like" to know how many 'files' there are in /tmp?
There are " 38" files in /tmp, according to the "wc" command
#!/bin/bash
function text1()
{
COUNT=$(\ls /tmp | wc -l)
cat <<EOF
$1 Would you "like" to know how many 'files' there are in /tmp?
There are "$COUNT" files in /tmp, according to the "wc" command
EOF
}
function main()
{
OUT=$(text1 "Welcome dev:")
echo "The text from the example function is: $OUT"
}
main
like this: put intro
outside your document ready, Good discussion here: http://forum.jquery.com/topic/how-do-i-declare-a-global-variable-in-jquery @thecodeparadox is awesomely fast :P anyways!
var intro;
$(document).ready(function() {
if ($('.intro_check').is(':checked')) {
intro = true;
$('.intro').wrap('<div class="disabled"></div>');
};
$('.intro_check').change(function(){
if(this.checked) {
intro = false;
$('.enabled').removeClass('enabled').addClass('disabled');
} else {
intro = true;
if($('.intro').exists()) {
$('.disabled').removeClass('disabled').addClass('enabled');
} else {
$('.intro').wrap('<div class="disabled"></div>');
}
}
});
});
from the bootstrap official site (and, almost, like Eric S. Bullington said.
https://getbootstrap.com/components/#navbar-default
the example navbar looks like:
<nav class="navbar navbar-default">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
...etc
to center the nav, that what i've done:
<div class="container-fluid" id="nav_center">
css:
@media (min-width:768px) { /* don't break navbar on small screen */
#nav_center {
width: 700px /* need to found your width according to your entry*/
}
}
work with class="container" and navbar-right or left, and of course you can replace id by class. :D
man ssh
gives me this options would could be useful.
-i identity_file Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for pro- tocol version 2. Identity files may also be specified on a per- host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in config- uration files).
So you could create an alias in your bash config with something like
alias ssh="ssh -i /path/to/private_key"
I haven't looked into a ssh configuration file, but like the -i
option this too could be aliased
-F configfile Specifies an alternative per-user configuration file. If a configuration file is given on the command line, the system-wide configuration file (/etc/ssh/ssh_config) will be ignored. The default for the per-user configuration file is ~/.ssh/config.
require 'json'
{"foo" => "bar"}.to_json

FYI - if you are importing a List into a JSP, chances are pretty good that you are violating MVC principles. Take a few hours now to read up on the MVC approach to web app development (including use of taglibs) - do some more googling on the subject, it's fascinating and will definitely help you write better apps.
If you are doing anything more complicated than a single JSP displaying some database results, please consider using a framework like Spring, Grails, etc... It will absolutely take you a bit more effort to get going, but it will save you so much time and effort down the road that I really recommend it. Besides, it's cool stuff :-)
Access Token
for Mobile Number and Country Code
(Server Side OR Client Side)You can get the mobile number
with your access_token
with this API
https://graph.accountkit.com/v1.1/me/?access_token=xxxxxxxxxxxx. Maybe, once you have the mobile number
and the id
, you can work with it to verify the user with your server & database
.
xxxxxxxxxx
above is the Access Token
{
"id": "61940819992708",
"phone": {
"number": "+91XX82923912",
"country_prefix": "91",
"national_number": "XX82923912"
}
}
Auth Code
for Access Token
(Server Side)If you have an Auth Code
instead, you can first get the Access Token
with this API
- https://graph.accountkit.com/v1.1/access_token?grant_type=authorization_code&code=xxxxxxxxxx&access_token=AA|yyyyyyyyyy|zzzzzzzzzz
xxxxxxxxxx
, yyyyyyyyyy
and zzzzzzzzzz
above are the Auth Code
, App ID
and App Secret
respectively.
{
"id": "619XX819992708",
"access_token": "EMAWdcsi711meGS2qQpNk4XBTwUBIDtqYAKoZBbBZAEZCZAXyWVbqvKUyKgDZBniZBFwKVyoVGHXnquCcikBqc9ROF2qAxLRrqBYAvXknwND3dhHU0iLZCRwBNHNlyQZD",
"token_refresh_interval_sec": XX92000
}
server-side
since the API
requires the APP Secret
which is not meant to be shared
for security reasons
.Good Luck.
Just got this, we can achieve it using onpaste:"return false"

The encryption methods described are symmetric key block ciphers.
Data Encryption Standard (DES) is the predecessor, encrypting data in 64-bit blocks using a 56 bit key. Each block is encrypted in isolation, which is a security vulnerability.
Triple DES extends the key length of DES by applying three DES operations on each block: an encryption with key 0, a decryption with key 1 and an encryption with key 2. These keys may be related.
DES and 3DES are usually encountered when interfacing with legacy commercial products and services.
AES is considered the successor and modern standard. http://en.wikipedia.org/wiki/Advanced_Encryption_Standard
I believe the use of Blowfish is discouraged.
It is highly recommended that you do not attempt to implement your own cryptography and instead use a high-level implementation such as GPG for data at rest or SSL/TLS for data in transit. Here is an excellent and sobering video on encryption vulnerabilities http://rdist.root.org/2009/08/06/google-tech-talk-on-common-crypto-flaws/
As I discovered having followed the advice in the answers given so far, you can get exceptions occuring without error messages being set, so to catch all problems you really need to get both the ErrorMessage and the Exception.
String messages = String.Join(Environment.NewLine, ModelState.Values.SelectMany(v => v.Errors)
.Select( v => v.ErrorMessage + " " + v.Exception));
or as an extension method
public static IEnumerable<String> GetErrors(this ModelStateDictionary modelState)
{
return modelState.Values.SelectMany(v => v.Errors)
.Select( v => v.ErrorMessage + " " + v.Exception).ToList();
}
Beware that Popen.communicate(input=s)
may give you trouble ifs
is too big, because apparently the parent process will buffer it before forking the child subprocess, meaning it needs "twice as much" used memory at that point (at least according to the "under the hood" explanation and linked documentation found here). In my particular case,s
was a generator that was first fully expanded and only then written tostdin
so the parent process was huge right before the child was spawned,
and no memory was left to fork it:
File "/opt/local/stow/python-2.7.2/lib/python2.7/subprocess.py", line 1130, in _execute_child
self.pid = os.fork()
OSError: [Errno 12] Cannot allocate memory
One option is to use numba
and the @jit
or @njit
decorator. I also made one or two little tweaks to your code (at least in Python 3, "list" is a keyword that shouldn't be used for a variable name):
@njit
def njit_product(lst):
p = lst[0] # first element
for i in lst[1:]: # loop over remaining elements
p *= i
return p
For timing purposes, you need to run once to compile the function first using numba. In general, the function will be compiled the first time it is called, and then called from memory after that (faster).
njit_product([1, 2]) # execute once to compile
Now when you execute your code, it will run with the compiled version of the function. I timed them using a Jupyter notebook and the %timeit
magic function:
product(b) # yours
# 32.7 µs ± 510 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
njit_product(b)
# 92.9 µs ± 392 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)
Note that on my machine, running Python 3.5, the native Python for
loop was actually the fastest. There may be a trick here when it comes to measuring numba-decorated performance with Jupyter notebooks and the %timeit
magic function. I am not sure that the timings above are correct, so I recommend trying it out on your system and seeing if numba gives you a performance boost.

If you are just looping through 10k rows in column A, then dump the row into a variant array and then loop through that.
You can then either add the elements to a new array (while adding rows when needed) and using Transpose() to put the array onto your range in one move, or you can use your iterator variable to track which row you are on and add rows that way.
Dim i As Long
Dim varray As Variant
varray = Range("A2:A" & Cells(Rows.Count, "A").End(xlUp).Row).Value
For i = 1 To UBound(varray, 1)
' do stuff to varray(i, 1)
Next
Here is an example of how you could add rows after evaluating each cell. This example just inserts a row after every row that has the word "foo" in column A. Not that the "+2" is added to the variable i during the insert since we are starting on A2. It would be +1 if we were starting our array with A1.
Sub test()
Dim varray As Variant
Dim i As Long
varray = Range("A2:A10").Value
'must step back or it'll be infinite loop
For i = UBound(varray, 1) To LBound(varray, 1) Step -1
'do your logic and evaluation here
If varray(i, 1) = "foo" Then
'not how to offset the i variable
Range("A" & i + 2).EntireRow.Insert
End If
Next
End Sub
Looks like the path you gave doesn't have any bootstrap files in them.
href="~/lib/bootstrap/dist/css/bootstrap.min.css"
Make sure the files exist over there , else point the files to the correct path, which should be in your case
href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"
Here is how I resolved it.
It is not the most secure way however it solved my problem as security was not an issue on internal servers.
Create a new file say password.txt
and store the password for the server where the file will be pasted. Save this to a location on the host server.
scp -W location/password.txt copy_file_location paste_file_location

Scripting languages are programming languages where the programs are typically delivered to end users in a readable textual form and where there is a program that can apparently execute that program directly. (The program may well compile the script internally; that's not relevant here because it is not visible to the user.)
It's relatively common for scripting languages to be able to support an interactive session where users can just type in their program and have it execute immediately. This is because this is a trivial extension of the essential requirement from the first paragraph; the main extra requirement is the addition of a mechanism to figure out when a typed-in statement is complete so that it can be sent to the execution engine.
Some of the tutorials I found that are easy to understand are:
It makes way more sense to break up your list into page-sized chunks, and only query your database one chunk at a time. This drastically reduces server processing time and page load time, as well as gives your user smaller pieces of info to digest, so he doesn't choke on whatever crap you're trying to feed him. The act of doing this is called pagination.
A basic pagination routine seems long and scary at first, but once you close your eyes, take a deep breath, and look at each piece of the script individually, you will find it's actually pretty easy stuff
The script:
// find out how many rows are in the table
$sql = "SELECT COUNT(*) FROM numbers";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = $r[0];
// number of rows to show per page
$rowsperpage = 10;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);
// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
// cast var as int
$currentpage = (int) $_GET['currentpage'];
} else {
// default page num
$currentpage = 1;
} // end if
// if current page is greater than total pages...
if ($currentpage > $totalpages) {
// set current page to last page
$currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
// set current page to first page
$currentpage = 1;
} // end if
// the offset of the list, based on current page
$offset = ($currentpage - 1) * $rowsperpage;
// get the info from the db
$sql = "SELECT id, number FROM numbers LIMIT $offset, $rowsperpage";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
// while there are rows to be fetched...
while ($list = mysql_fetch_assoc($result)) {
// echo data
echo $list['id'] . " : " . $list['number'] . "<br />";
} // end while
/****** build the pagination links ******/
// range of num links to show
$range = 3;
// if not on page 1, don't show back links
if ($currentpage > 1) {
// show << link to go back to page 1
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'><<</a> ";
// get previous page num
$prevpage = $currentpage - 1;
// show < link to go back to 1 page
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'><</a> ";
} // end if
// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
// if it's a valid page number...
if (($x > 0) && ($x <= $totalpages)) {
// if we're on current page...
if ($x == $currentpage) {
// 'highlight' it but don't make a link
echo " [<b>$x</b>] ";
// if not current page...
} else {
// make it a link
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
} // end else
} // end if
} // end for
// if not on last page, show forward and last page links
if ($currentpage != $totalpages) {
// get next page
$nextpage = $currentpage + 1;
// echo forward link for next page
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>></a> ";
// echo forward link for lastpage
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$totalpages'>>></a> ";
} // end if
/****** end build pagination links ******/

This tutorial is intended for developers who wish to give their users the ability to step through a large number of database rows in manageable chunks instead of the whole lot in one go.
For example: To go My folder project on source, i need to up two folder. I make this algorim to 2 days week and into four hour
public static void LimpiarArchivosViejos()
{
DayOfWeek today = DateTime.Today.DayOfWeek;
int hora = DateTime.Now.Hour;
if(today == DayOfWeek.Monday || today == DayOfWeek.Tuesday && hora < 12 && hora > 8)
{
CleanPdfOlds();
CleanExcelsOlds();
}
}
private static void CleanPdfOlds(){
string[] files = Directory.GetFiles("../../Users/Maxi/Source/Repos/13-12-2017_config_pdfListados/ApplicaAccWeb/Uploads/Reports");
foreach (string file in files)
{
FileInfo fi = new FileInfo(file);
if (fi.CreationTime < DateTime.Now.AddDays(-7))
fi.Delete();
}
}
private static void CleanExcelsOlds()
{
string[] files2 = Directory.GetFiles("../../Users/Maxi/Source/Repos/13-12-2017_config_pdfListados/ApplicaAccWeb/Uploads/Excels");
foreach (string file in files2)
{
FileInfo fi = new FileInfo(file);
if (fi.CreationTime < DateTime.Now.AddDays(-7))
fi.Delete();
}
}
I was able to change the button's text like this:
import android.widget.RemoteViews;
//grab the layout, then set the text of the Button called R.id.Counter:
RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.my_layout);
remoteViews.setTextViewText(R.id.Counter, "Set button text here");
this is very easy way to do this without any Library: if the OS version is not supported - under kitkat - so nothing happend. i do this steps:
<View android:id="@+id/statusBarBackground" android:layout_width="match_parent" android:layout_height="wrap_content" />
then i made this method:
public void setStatusBarColor(View statusBar,int color){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow();
w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
//status bar height
int actionBarHeight = getActionBarHeight();
int statusBarHeight = getStatusBarHeight();
//action bar height
statusBar.getLayoutParams().height = actionBarHeight + statusBarHeight;
statusBar.setBackgroundColor(color);
}
}
also you need those both methods to get action Bar & status bar height:
public int getActionBarHeight() {
int actionBarHeight = 0;
TypedValue tv = new TypedValue();
if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true))
{
actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());
}
return actionBarHeight;
}
public int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
then the only thing you need is this line to set status bar color:
setStatusBarColor(findViewById(R.id.statusBarBackground),getResources().getColor(android.R.color.white));
The way you do it is pretty standard. You can define a utility clamp
function:
/**
* Returns a number whose value is limited to the given range.
*
* Example: limit the output of this computation to between 0 and 255
* (x * 255).clamp(0, 255)
*
* @param {Number} min The lower boundary of the output range
* @param {Number} max The upper boundary of the output range
* @returns A number in the range [min, max]
* @type Number
*/
Number.prototype.clamp = function(min, max) {
return Math.min(Math.max(this, min), max);
};
(Although extending language built-ins is generally frowned upon)
For Windows we can use
cd
and for Linux
pwd
command is there.
with a form, just set method
to "post"
<form action="blah.php" method="post">
<input type="text" name="data" value="mydata" />
<input type="submit" />
</form>
You can simplify this code to:
DirectorySearcher searcher = new DirectorySearcher();
searcher.Filter = "(&(objectCategory=user)(cn=steve.evans))";
SearchResultCollection results = searcher.FindAll();
if (results.Count == 1)
{
//do what you want to do
}
else if (results.Count == 0)
{
//user does not exist
}
else
{
//found more than one user
//something is wrong
}
If you can narrow down where the user is you can set searcher.SearchRoot to a specific OU that you know the user is under.
You should also use objectCategory instead of objectClass since objectCategory is indexed by default.
You should also consider searching on an attribute other than CN. For example it might make more sense to search on the username (sAMAccountName) since it's guaranteed to be unique.
I faced the problem with display:none
I have several horizontal bars with transition effects but I wanted to show only part of that container and fold the rest while maintaining the effects. I reproduced a small demo here
The obvious was to wrap those hidden animated bars in a div then toggle that element's height and opacity
.hide{
opacity: 0;
height: 0;
}
.bars-wrapper.expanded > .hide{
opacity: 1;
height: auto;
}
The animation works well but the issue was that these hidden bars were still consuming space on my page and overlapping other elements
so adding display:none
to the hidden wrapper .hide
solves the margin issue but not the transition, neither applying display:none
or height:0;opacity:0
works on the children elements.
So my final workaround was to give those hidden bars a negative and absolute position and it worked well with CSS transitions.
Simplest way - This will keep the image size as it is and fill the other area with space, this way all the images will take same specified space regardless of the image size without stretching
.img{
width:100px;
height:100px;
/*Scale down will take the necessary specified space that is 100px x 100px without stretching the image*/
object-fit:scale-down;
}
Using @mmacaulay , I came up with this for bool:
// MVC Work around for checkboxes.
bool active = (Request.Form["active"] == "on");
If checked active = true
If unchecked active = false
Prepared statements / parameterized queries are generally sufficient to prevent 1st order injection on that statement*. If you use un-checked dynamic sql anywhere else in your application you are still vulnerable to 2nd order injection.
2nd order injection means data has been cycled through the database once before being included in a query, and is much harder to pull off. AFAIK, you almost never see real engineered 2nd order attacks, as it is usually easier for attackers to social-engineer their way in, but you sometimes have 2nd order bugs crop up because of extra benign '
characters or similar.
You can accomplish a 2nd order injection attack when you can cause a value to be stored in a database that is later used as a literal in a query. As an example, let's say you enter the following information as your new username when creating an account on a web site (assuming MySQL DB for this question):
' + (SELECT UserName + '_' + Password FROM Users LIMIT 1) + '
If there are no other restrictions on the username, a prepared statement would still make sure that the above embedded query doesn't execute at the time of insert, and store the value correctly in the database. However, imagine that later the application retrieves your username from the database, and uses string concatenation to include that value a new query. You might get to see someone else's password. Since the first few names in users table tend to be admins, you may have also just given away the farm. (Also note: this is one more reason not to store passwords in plain text!)
We see, then, that prepared statements are enough for a single query, but by themselves they are not sufficient to protect against sql injection attacks throughout an entire application, because they lack a mechanism to enforce all access to a database within an application uses safe code. However, used as part of good application design — which may include practices such as code review or static analysis, or use of an ORM, data layer, or service layer that limits dynamic sql — prepared statements are the primary tool for solving the Sql Injection problem. If you follow good application design principles, such that your data access is separated from the rest of your program, it becomes easy to enforce or audit that every query correctly uses parameterization. In this case, sql injection (both first and second order) is completely prevented.
*It turns out that MySql/PHP are (okay, were) just dumb about handling parameters when wide characters are involved, and there is still a rare case outlined in the other highly-voted answer here that can allow injection to slip through a parameterized query.
Just set the className
attribute of the real DOM element to ''
(nothing).
$('#item')[0].className = ''; // the real DOM element is at [0]
Edit: Other people have said that just calling removeClass
works - I tested this with the Google JQuery Playground: http://savedbythegoog.appspot.com/?id=ag5zYXZlZGJ5dGhlZ29vZ3ISCxIJU2F2ZWRDb2RlGIS61gEM ... and it works. So you can also do it this way:
$("#item").removeClass();
1) Check if you are using OnItemClickListener or OnClickListener (which is not supported for ListView)
Documentation Android Developers ListView
2) Check if you added Listener to your ListView properly. It's hooked on ListView not on ListAdapter!
ListView.setOnItemClickListener(listener);
3) If you need to use OnClickListener, check if you do use DialogInterface.OnClickListener
or View.OnClickListener
(they can be easily exchanged if not validated or if using both of them)
div.style.removeProperty('zoom');
var oldString = "stackoverflow";
var str=oldString.replace(/stackover/g,"NO");
$scope.newString= str;
It works for me. Use an intermediate variable.
In eclipse help documentation, we can all icons information as follows. Common path for all eclipse versions except eclipse version:
Add below code to styles.xml
file
<style name="LayoutPageTheme" parent="@style/Theme.AppCompat.Light.NoActionBar">
<item name="android:windowActionBarOverlay">true</item>
<!-- Support library compatibility -->
<item name="windowActionBarOverlay">true</item>

Don't forget to write: android:background="@android:color/transparent"
First of all you have to fetch the remote repository:
git fetch remoteName
Than you can create the new branch and set it up to track the remote branch you want:
git checkout -b newLocalBranch remoteName/remoteBranch
You can also use "git branch --track" instead of "git checkout -b" as max specified.
git branch --track newLocalBranch remoteName/remoteBranch
Well to make the decimal into a percent you can do this,
float percentage = (correct * 100.0f) / questionNum;
If you Use Swift 2.0+
self.yourView.layer.borderWidth = 1
self.yourView.layer.borderColor = UIColor(red:222/255, green:225/255, blue:227/255, alpha: 1).cgColor
More oin regards to question part 4 How do you e-mail that error to an email address? The error_log function has email destination too. http://php.net/manual/en/function.error-log.php
Agha, here I found an example that shows a usage. Send errors message via email using error_log()
error_log($this->_errorMsg, 1, ADMIN_MAIL, "Content-Type: text/html; charset=utf8\r\nFrom: ".MAIL_ERR_FROM."\r\nTo: ".ADMIN_MAIL);
There could be a mistake in @JARH's answer in the case of a multivariable regression. (I do not have enough reputation to comment.)
In the following line:
p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-1))) for i in ts_b]
,
the t-values follows a chi-squared distribution of degree len(newX)-1
instead of following a chi-squared distribution of degree len(newX)-len(newX.columns)-1
.
So this should be:
p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-len(newX.columns)-1))) for i in ts_b]
(See t-values for OLS regression for more details)
The trick here is that Controls
is not a List<>
or IEnumerable
but a ControlCollection
.
I recommend using an extension of Control that will return something more..queriyable ;)
public static IEnumerable<Control> All(this ControlCollection controls)
{
foreach (Control control in controls)
{
foreach (Control grandChild in control.Controls.All())
yield return grandChild;
yield return control;
}
}
Then you can do :
foreach(var textbox in this.Controls.All().OfType<TextBox>)
{
// Apply logic to the textbox here
}
Open the hosts file located at : **C:\windows\system32\drivers\etc**.
Add the following at end of this file :
YourServerIP YourDNS
Example:
198.168.1.1 maps.google.com
I had the same issue and find an easier solution
It is due to Vs2012 adding the following to the csproj file:
<PropertyGroup>
<VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''">10.0</VisualStudioVersion>
<VSToolsPath Condition="'$(VSToolsPath)' == ''">$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)</VSToolsPath>
</PropertyGroup>
You can safely remove that part and your solution will build.
As Sielu pointed out you have to ensure that the .proj file begin with
<Project ToolsVersion="12"
otherwise the next time you open the project with visual studio 2010, it will add the removed node again.
Otherwise, if you need to use webdeploy or you use a build server, the above solution will not work but you can specify the VisualStudioVersion
property in your build script:
msbuild myproject.csproj /p:VisualStudioVersion=12.0
or edit your build definition:
Deleting the .git
folder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:
Checkout
git checkout --orphan latest_branch
Add all the files
git add -A
Commit the changes
git commit -am "commit message"
Delete the branch
git branch -D main
Rename the current branch to main
git branch -m main
Finally, force update your repository
git push -f origin main
PS: this will not keep your old commit history around
You can put the above answers into one line like this. And you don't need to write the function.
<asp:Button runat="server" ID="btnUserDelete" Text="Delete" CssClass="GreenLightButton"
OnClick="BtnUserDelete_Click" meta:resourcekey="BtnUserDeleteResource1"
OnClientClick="if ( !confirm('Are you sure you want to delete this user?')) return false;" />
SELECT *

You are using multiple versions of the Android Support Libraries:
compile 'com.android.support:appcompat-v7:26.0.0-alpha1'
compile 'com.android.support:cardview-v7:26.0.0-alpha1'
compile 'com.android.support:design:25+'
Two are 26.0.0-alpha1
, and one is using 25+
.
Pick one concrete version and use it for all three of these. Since your compileSdkVersion
is not O
, use 25.3.1
for all three of these libraries, resulting in:
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
$ alias gpuom='git push origin master'
$ alias
hit Enter.$ vim ~/.bashrc
and hit Enter (I'm guessing you are familiar with vim).#My custom aliases
alias gpuom='git push origin master'
alias gplom='git pull origin master'
$ alias
hit Enter.Using ToString("HH:mm")
certainly gives you what you want as a string.
If you want the current hour/minute as numbers, string manipulation isn't necessary; you can use the TimeOfDay
property:
TimeSpan timeOfDay = fechaHora.TimeOfDay;
int hour = timeOfDay.Hours;
int minute = timeOfDay.Minutes;
I ran into this error after my client PC crashed, the jest --watch
command I was running on the server persisted, and I tried to run jest --watch
again.
The addition to /etc/sysctl.conf
described in the answers above worked around this issue, but it was also important to find my old process via ps aux | grep node
and kill
it.
This answer is going to be for the question
How to create a new eclipse project and add a folder or a new package into the project, or how to build a new project for existing java files.
this worked for me I hope it helps others. Thank you.
Here's what I ended up doing when I had the same problem (at least I think it's the same problem). I went into directory A and ran git init
.
Since I didn't want the files in directory A to be followed by git, I edited .gitignore and added the existing files to it. After this I ran git remote add origin '<url>' && git pull origin master
et voíla, B is "cloned" into A without a single hiccup.
http://en.wikibooks.org/wiki/LaTeX/Tables#Resize_tables talks about two ways to do this.
I used:
\scalebox{0.7}{
\begin{tabular}
...
\end{tabular}
}
iList.SelectMany(x => x).ToArray()
In Java, all non-static methods are by default "virtual functions." Only methods marked with the keyword final, which cannot be overridden, along with private methods, which are not inherited, are non-virtual.
The best way to handle the LazyInitializationException
is to fetch it upon query time, like this:
select t
from Topic t
left join fetch t.comments
You should ALWAYS avoid the following anti-patterns:
FetchType.EAGER
hibernate.enable_lazy_load_no_trans
Hibernate configuration propertyTherefore, make sure that your FetchType.LAZY
associations are initialized at query time or within the original @Transactional
scope using Hibernate.initialize
for secondary collections.
For XAMMP versions >=7.5.9-0 also change the DocumentRoot in file "/opt/lampp/etc/extra/httpd-ssl.conf" accordingly.
Do what google commands you to do! here: http://developer.android.com/resources/faq/framework.html#3
You might consider writing an iterator instead, which allows you to use normal 'for' loop syntax like '++'. I searched and found a similar question answered here on StackOverflow which gives pointers on making DateTime iterable.
You can use Calendar's method
func date(byAdding component: Calendar.Component, value: Int, to date: Date, wrappingComponents: Bool = default) -> Date?
to add any Calendar.Component
to any Date
. You can create a Date extension to add x minutes to your UIDatePicker
's date:
Xcode 8 and Xcode 9 • Swift 3.0 and Swift 4.0
extension Date {
func adding(minutes: Int) -> Date {
return Calendar.current.date(byAdding: .minute, value: minutes, to: self)!
}
}
Then you can just use the extension method to add minutes to the sender (UIDatePicker):
let section1 = sender.date.adding(minutes: 5)
let section2 = sender.date.adding(minutes: 10)
Playground testing:
Date().adding(minutes: 10) // "Jun 14, 2016, 5:31 PM"

Probably, like me, you have a wrong root viewController
I want to display a ViewController
in a non-UIViewController
context,
So I can't use such code:
[self presentViewController:]
So, I get a UIViewController:
[[[[UIApplication sharedApplication] delegate] window] rootViewController]
For some reason (logical bug), the rootViewController
is something other than expected (a normal UIViewController
). Then I correct the bug, replacing rootViewController
with a UINavigationController
, and the problem is gone.
The above error can occur for multiple cases during servlet startup / request. Hope you check the full stack trace of the server log, If you have tomcat, you can also see the exact causes in html preview of the 500 Internal Server Error page.
Weird thing is, if you try to hit the request url a second time, you would get 404 Not Found page.
You can also debug this issue, by placing breakpoints on all the classes constructor initialization block, whose objects are created during servlet startup/request.
In my case, I didn't had javaassist jar loaded for the Weld CDI injection to work. And it shown NoClassDefFound Error.

You should subscribe as a SensorEventListener
, and get the accelerometer
data.
Once you have it, you should monitor for sudden change in direction (sign) of acceleration on a certain axis. It would be a good indication for the 'shake'
movement of device.
This is an improvement on @thisisboris answer. It adds a current value to data, so the code can control when a variable set to the current value is changed.
(function()
{
// Initialize the previous-attribute
var selects = $( 'select' );
$.each( selects, function( index, myValue ) {
$( myValue ).data( 'mgc-previous', myValue.value );
$( myValue ).data( 'mgc-current', myValue.value );
});
// Listen on the body for changes to selects
$('body').on('change', 'select',
function()
{
alert('I am a body alert');
$(this).data('mgc-previous', $(this).data( 'mgc-current' ) );
$(this).data('mgc-current', $(this).val() );
}
);
})();
Using http.createServer
is very low-level and really not useful for creating web applications as-is.
A good framework to use on top of it is Express, and I would seriously suggest using it. You can install it using npm install express
.
When you have, you can create a basic application to handle your form:
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true }));
//app.use(express.bodyParser());
app.post('/myaction', function(req, res) {
res.send('You sent the name "' + req.body.name + '".');
});
app.listen(8080, function() {
console.log('Server running at http://127.0.0.1:8080/');
});
You can make your form point to it using:
<form action="http://127.0.0.1:8080/myaction" method="post">
The reason you can't run Node on port 80 is because there's already a process running on that port (which is serving your index.html
). You could use Express to also serve static content, like index.html
, using the express.static
middleware.
This is a working example:
jdbc:mysql://localhost:3306/database?useUnicode=yes&characterEncoding=UTF-8&serverTimezone=Europe/Moscow
A Simple Approach will be to use a normal link and add Bootstrap modal effect to it. Just make use of my Code, hopefully you will get it run.

If you are using a mac and sublime text 3, this is what you do.
Go to your /Packages/User/
and create a file called Python.sublime-settings
.
Typically /Packages/User
is inside your ~/Library/Application Support/Sublime Text 3/Packages/User/Python.sublime-settings
if you are using mac os x.
Then you put this in the Python.sublime-settings
.
{
"tab_size": 4,
"translate_tabs_to_spaces": false
}
Credit goes to Mark Byer's answer, sublime text 3 docs and python style guide.
This answer is mostly for readers who had the same issue and stumble upon this and are using sublime text 3 on Mac OS X.
There are so many solution but nobody suggested if the color resource xml file already have color then we can pick directly from there also as below:
ImageView imageView = (ImageView) findViewById(R.id.imageview);
imageView.setColorFilter(getString(R.color.your_color));
I had this problem. I searched the internet, took all advices, changes configurations, but the problem is still there. Finally with the help of the server administrator, he found that the problem lies in MySQL database column definition. one of the columns in the a table was assigned to 'Longtext' which leads to allocate 4,294,967,295 bites of memory. It seems working OK if you don't use MySqli prepare statement, but once you use prepare statement, it tries to allocate that amount of memory. I changed the column type to Mediumtext which needs 16,777,215 bites of memory space. The problem is gone. Hope this help.

was a POD-type, this would perform value-initialization (it doesn't apply here).
/* 2 */ Foo* foo2 = new Foo;
Identical to before, because Foo
is not a POD type.
/* 3 */ Foo foo3;
Creates a Foo
object called foo3
in automatic storage.
/* 4 */ Foo foo4 = Foo::Foo();
Uses copy-initialization to create a Foo
object called foo4
in automatic storage.
/* 5 */ Bar* bar1 = new Bar ( *new Foo() );
Uses Bar
's conversion constructor to create an object of type Bar
in dynamic storage. bar1
is a pointer to it.
/* 6 */ Bar* bar2 = new Bar ( *new Foo );
Same as before.
/* 7 */ Bar* bar3 = new Bar ( Foo foo5 );
This is just invalid syntax. You can't declare a variable there.
/* 8 */ Bar* bar3 = new Bar ( Foo::Foo() );
Would work and work by the same principle to 5 and 6 if bar3
wasn't declared on in 7.
5 & 6 contain memory leaks.
Syntax like new Bar ( Foo::Foo() );
is not usual. It's usually new Bar ( (Foo()) );

val greenText = SpannableString("This is green,")
greenText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someGreenColor), null), 0, greenText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
yourTextView.text = greenText
val yellowText = SpannableString("this is yellow, ")
yellowText.setSpan(ForegroundColorSpan(resources.getColor(R.color.someYellowColor), null), 0, yellowText.length, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)

Besides Apache Commons, also see String.format
which should be able to take care of simple padding (e.g. with spaces).
The following works for me. Add the following method to the entity that is not the owner of the relationship (Group)
@PreRemove
private void removeGroupsFromUsers() {
for (User u : users) {
u.getGroups().remove(this);
}
}
Keep in mind that for this to work, the Group must have an updated list of Users (which is not done automatically). so everytime you add a Group to the group list in User entity, you should also add a User to the user list in the Group entity.
Edit
A better way to do this is:
Create your own less file as a main less file ( like bootstrap.less ).
Import all bootstrap less files you need. (in this case, you just need to Import all responsive less files but responsive-1200px-min.less
)
If you need to modify anything in original bootstrap less file, you just need to write your own less to overwrite bootstrap's less code. (Just remember to put your less code/file after @import { /* bootstrap's less file */ };
).
Original
I have the same problem. This is how I fixed it.
Find the media query:
@media (max-width:1200px) ...
Remove it. (I mean the whole thing , not just @media (max-width:1200px)
)
Since the default width of Bootstrap is 940px, you don't need to do anything.
If you want to have your own max-width
, just modify the css rule in the media query that matches your desired width.
Try this
SELECT *
FROM people P
where P.IDNo in (SELECT DISTINCT IDNo
FROM people)
I know this post is old but I ran into this same issue and finally figured out a solution to determine which column was causing the problem and report it back as needed. I determined that colid
returned in the SqlException is not zero based so you need to subtract 1 from it to get the value. After that it is used as the index of the _sortedColumnMappings
ArrayList of the SqlBulkCopy instance not the index of the column mappings that were added to the SqlBulkCopy instance. One thing to note is that SqlBulkCopy will stop on the first error received so this may not be the only issue but at least helps to figure it out.
try
{
bulkCopy.WriteToServer(importTable);
sqlTran.Commit();
}
catch (SqlException ex)
{
if (ex.Message.Contains("Received an invalid column length from the bcp client for colid"))
{
string pattern = @"\d+";
Match match = Regex.Match(ex.Message.ToString(), pattern);
var index = Convert.ToInt32(match.Value) -1;
FieldInfo fi = typeof(SqlBulkCopy).GetField("_sortedColumnMappings", BindingFlags.NonPublic | BindingFlags.Instance);
var sortedColumns = fi.GetValue(bulkCopy);
var items = (Object[])sortedColumns.GetType().GetField("_items", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(sortedColumns);
FieldInfo itemdata = items[index].GetType().GetField("_metadata", BindingFlags.NonPublic | BindingFlags.Instance);
var metadata = itemdata.GetValue(items[index]);
var column = metadata.GetType().GetField("column", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance).GetValue(metadata);
var length = metadata.GetType().GetField("length", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance).GetValue(metadata);
throw new DataFormatException(String.Format("Column: {0} contains data with a length greater than: {1}", column, length));
}

You can use partition or chunks function from funcy library:
from funcy import partition
for a, b, c, d in partition(4, ints):
foo += a * b * c * d
These functions also has iterator versions ipartition
and ichunks
, which will be more efficient in this case.
You can also peek at their implementation.
I tried to "Maven > Reimport" but the only thing that actually fixed it was to close the project, delete the .idea directory, and reopen the project.
For me, the only way to reset the failed cherry-pick-attempt was
git reset --hard HEAD
As an addition
To disable all rules for the next line // tslint:disable-next-line
To disable specific rules for the next line: // tslint:disable-next-line:rule1 rule2...
To disable all rules for the current line: someCode(); // tslint:disable-line
To disable specific rules for the current line: someCode(); // tslint:disable-line:rule1
The finalizeQueue may be too long
i think that java may require GC.SuppressFinalize() & GC.ReRegisterForFinalize() to let user reduce the finalizedQueue length explicitly
if the JVM' source code is available, may implement these method ourself, such as android ROM maker
In my case it was Bootstrap popup in opened state.
Text input was in another calendar popup on top of Bootstrap one, input got its focus back after removing tabindex="-1"
attribute from Bootstrap modal.
Somehow I fixed it by changing
<add name="Access-Control-Allow-Headers"
value="Origin, X-Requested-With, Content-Type, Accept, Authorization"
/>
to
<add name="Access-Control-Allow-Headers"
value="Origin, Content-Type, Accept, Authorization"
/>
In postman, even after following the accepted answer, I was getting an empty request body. The issue turned out to be not passing a header called
Content-Length : <calculated when request is sent>
This header was present by default (along with 5 others) which I have disabled. Enable this and you'll receive the request body.
I have no idea how it can work automatically, but you can copy "], " together with new line and then use replace function.
You should have a default server for catch-all, you can return 404
or better to not respond at all (will save some bandwidth) by returning 444
which is nginx specific HTTP response that simply close the connection and return nothing
server {
listen 80 default_server;
server_name _; # some invalid name that won't match anything
return 444;
}
I don't think answer from Vincent Malgrat is correct. When NVARCHAR2
was introduced long time ago nobody was even talking about Unicode.
Initially Oracle provided VARCHAR2
and NVARCHAR2
to support localization. Common data (include PL/SQL) was hold in VARCHAR2
, most likely US7ASCII
these days. Then you could apply NLS_NCHAR_CHARACTERSET
individually (e.g. WE8ISO8859P1
) for each of your customer in any country without touching the common part of your application.
Nowadays character set AL32UTF8
is the default which fully supports Unicode. In my opinion today there is no reason anymore to use NLS_NCHAR_CHARACTERSET
, i.e. NVARCHAR2
, NCHAR2
, NCLOB
. Note, there are more and more Oracle native functions which do not support NVARCHAR2, so you should really avoid it. Maybe the only reason is when you have to support mainly Asian characters where AL16UTF16
consumes less storage compared to AL32UTF8
.
As an aside to what folks have been posting here, I've heard that concatenation can be much faster than join in modern javascript vms. Meaning:
var a =
[ "hey man, this is on a line",
"and this is on another",
"and this is on a third"
].join('\n');
Will be slower than:
var a = "hey man, this is on a line\n" +
"and this is on another\n" +
"and this is on a third";
In certain cases. http://jsperf.com/string-concat-versus-array-join/3
As another aside, I find this one of the more appealing features in Coffeescript. Yes, yes, I know, haters gonna hate.

Its especially nice for html snippets. I'm not saying its a reason to use it, but I do wish it would land in ecma land :-(.

PHP was not designed to explicitly give you a pure REST (GET, POST, PUT, PATCH, DELETE) like interface for handling HTTP requests.
However, the $_SERVER
, $_COOKIE
, $_POST
, $_GET
, and $_FILES
superglobals, and the function filter_input_array()
are very useful for the average person's / layman's needs.
The number one hidden advantage of $_POST
(and $_GET
) is that your input data is url-decoded automatically by PHP. You never even think about having to do it, especially for query string parameters within a standard GET
request, or HTTP body data submitted with a POST
request.
Those studying the underlying HTTP protocol and its various request methods come to understand that there are many HTTP request methods, including the often referenced PUT
, PATCH
(not used in Google's Apigee), and DELETE
.
In PHP, there are no superglobals or input filter functions for getting HTTP request body data when POST
is not used. What are disciples of Roy Fielding to do? ;-)
That being said, as you advance in your PHP programming knowledge and want to use JavaScript's XmlHttpRequest
object (jQuery for some), you come to see the limitation of this scheme.
$_POST
limits you to the use of two media types in the HTTP Content-Type
header:
application/x-www-form-urlencoded
, andmultipart/form-data
Thus, if you want to send data values to PHP on the server, and have it show up in the $_POST
superglobal, then you must urlencode it on the client-side and send said data as key/value pairs--an inconvenient step for novices (especially when trying to figure out if different parts of the URL require different forms of urlencoding: normal, raw, etc..).
For all you jQuery users, the $.ajax()
method is converting your JSON to URL encoded key/value pairs before transmitting them to the server. You can override this behavior by setting processData: false
. Just read the $.ajax() documentation, and don't forget to send the correct media type in the Content-Type header.
Even if you use php://input
instead of $_POST
for your HTTP POST
request body data, it will not work with an HTTP Content-Type
of multipart/form-data
This is the content type that you use on an HTML form when you want to allow file uploads!
<form enctype="multipart/form-data" accept-charset="utf-8" action="post">
<input type="file" name="resume">
</form>
Therefore, in traditional PHP, to deal with a diversity of content types from an HTTP POST
request, you will learn to use $_POST
or filter_input_array(POST)
, $_FILES
, and php://input
. There is no way to just use one, universal input source for HTTP POST
requests in PHP.
You cannot get files through $_POST
, filter_input_array(POST), or php://input
, and you cannot get JSON/XML/YAML in either filter_input_array(POST)
or $_POST
.
php://input is a read-only stream that allows you to read raw data from the request body...php://input is not available with enctype="multipart/form-data".
PHP frameworks like Codeigniter 4 and Laravel use a facade to provide a cleaner interface (IncomingRequest
or Request
objects) to the above. This is why professional PHP developers use frameworks instead of raw PHP.
Of course, if you like to program, you can devise your own facade object to provide what frameworks do. It is because I have taken time to investigate this issue that I am able to write this answer.
Typically, if you are doing a normal, synchronous (when the entire page redraws) HTTP requests with an HTML form, the user-agent (web browser) will urlencode your form data for you. If you want to do an asynchronous HTTP requests using the XmlHttpRequest
object, then you must fashion a urlencoded string and send it, if you want that data to show up in the $_POST
superglobal.
Converting from a JavaScript array or object to a urlencoded string bothers many developers (even with new APIs like Form Data). They would much rather just be able to send JSON, and it would be more efficient for the client code to do so.
Remember (wink, wink), the average web developer does not learn to use the XmlHttpRequest
object directly, global functions, string functions, array functions, and regular expressions like you and I ;-). Urlencoding for them is a nightmare. ;-)
PHP's lack of intuitive XML and JSON handling turns many people off. You would think it would be part of PHP by now (sigh).
XML, JSON, and YAML all have media types that can be put into an HTTP Content-Type
header.
Look how many media-types (formerly, MIME types) are defined by IANA.
Look how many HTTP headers there are.
Using the php://input
stream allows you to circumvent the baby-sitting / hand holding level of abstraction that PHP has forced on the world. :-) With great power comes great responsibility!
Now, before you deal with data values streamed through php://input
, you should / must do a few things.
AH, HA! Yes, you might want the data stream being sent into your application to be UTF-8 encoded, but how can you know if it is or not?
php://input
.Are you going to attempt to handle stream data without knowing how much is there first? That is a terrible idea. You cannot rely exclusively on the HTTP Content-Length
header for guidance on the size of streamed input because it can be spoofed.
You are going to need a:
Are you going to attempt to convert stream data to UTF-8 without knowing the current encoding of the stream? How? The iconv stream filter (iconv stream filter example) seems to want a starting and ending encoding, like this.
'convert.iconv.ISO-8859-1/UTF-8'
Thus, if you are conscientious, you will need:
(Update: 'convert.iconv.UTF-8/UTF-8'
will force everything to UTF-8, but you still have to account for characters that the iconv library might not know how to translate. In other words, you have to some how define what action to take when a character cannot be translated: 1) Insert a dummy character, 2) Fail / throw and exception).
You cannot rely exclusively on the HTTP Content-Encoding
header, as this might indicate something like compression as in the following. This is not what you want to make a decision off of in regards to iconv.
Content-Encoding: gzip
Part I: HTTP Request Related
Part II: Stream Data Related
Part III: Data Type Related
(Remember, the data can still be a URL encoded string which you must then parse and URL decode).
Part IV: Data Value Related
Filter input data.
Validate input data.
The $_POST
superglobal, along with php.ini settings for limits on input, are simpler for the layman. However, dealing with character encoding is much more intuitive and efficient when using streams because there is no need to loop through superglobals (or arrays, generally) to check input values for the proper encoding.
If you're geting [object object]
then use JSON.stringify
fs.writeFile('./data.json', JSON.stringify(obj) , 'utf-8');

From the last java-12 release multiple constants in the same case label is available in preview language feature
It is available in a JDK feature release to provoke developer feedback based on real world use; this may lead to it becoming permanent in a future Java SE Platform.

};
Using ScrollView
is not very difficult. You can just add one to your layout and put whatever you want to scroll inside. ScrollView
only takes one child so if you want to put a few things inside then you should make the first thing be something like a LinearLayout
.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- things to scroll -->
</LinearLayout>
</ScrollView>
If you want to scroll things horizontally, then use a HorizontalScrollView
.
As is talked about in this post, sometimes you want the ScrollView
content to fill the screen. For example, if you had some buttons at the end of a readme. You want the buttons to always be at the end of the text and at bottom of the screen, even if the text doesn't scroll.
If the content scrolls, everything is fine. However, if the content is smaller than the size of the screen, the buttons are not at the bottom.
This can be solved with a combination of using fillViewPort
on the ScrollView
and using a layout weight on the content. Using fillViewPort
makes the ScrollView
fill the parent area. Setting the layout_weight
on one of the views in the LinearLayout
makes that view expand to fill any extra space.
Here is the XML
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"> <--- fillViewport
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">

android:layout_weight="1" <--- set layout_weight
android:layout_width="match_parent"
android:padding="6dp"
android:text="hello"/>
<LinearLayout
android:layout_height="wrap_content" <--- wrap_content
android:layout_width="match_parent"
android:background="@android:drawable/bottom_bar"
android:gravity="center_vertical">

android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Accept" />
<Button

android:layout_height="wrap_content"
android:text="Refuse" />
</LinearLayout>
</LinearLayout>
</ScrollView>

I wrote this a while ago to remind myself of what a closure is and how it works in JS.
A closure is a function that, when called, uses the scope in which it was declared, not the scope in which it was called. In javaScript, all functions behave like this. Variable values in a scope persist as long as there is a function that still points to them. The exception to the rule is 'this', which refers to the object that the function is inside when it is called.
var z = 1;
function x(){
var z = 2;
y(function(){
alert(z);
});
}
function y(f){
var z = 3;
f();
}
x(); //alerts '2'
Try this:
.rowhighlight > td { background: green;}
Also, if you're just looking for a specific value nested within the JSON content you can do something like so:
yourJObject.GetValue("jsonObjectName").Value<string>("jsonPropertyName");
And so on from there.
This could help if you don't want to bear the cost of converting the entire JSON into a C# object.
remove the .git
folder in your project root folder
if you installed submodules and want to remove their git, also remove .git

First, do not use DataOutputStream
unless it’s really necessary. Second:
Socket socket = new Socket("host", port);
OutputStream socketOutputStream = socket.getOutputStream();
socketOutputStream.write(message);
Of course this lacks any error checking but this should get you going. The JDK API Javadoc is your friend and can help you a lot.
I just struggled with this. I upgraded from sweetalert 1 -> 2. This library: https://sweetalert.js.org/guides/
The example from documentation "string" doesn't work as I expected. You just can't put it like this.
content: `my es6 string <strong>template</strong>`
How I solved it:
const template = (`my es6 string <strong'>${variable}</strong>`);
content: {
element: 'p',
attributes: {
innerHTML: `${template}`,
},
}
There is no documentation how to do this, it was pure trial and error, but at least seems to work.
Yes, you can overload main method in Java. you have to call the overloaded main method from the actual main method.
Since you can also input numbers as well as fixed type strings, the answer should actually be:
function isBlank(value) {
return $.trim(value);
}
Delete node_modules
rm -r node_modules
install packages again
npm install
We had this same issue. We solved it adding 'length' to entity attribute definition:
@Column(columnDefinition="text", length=10485760)
private String configFileXml = "";
Without converting to string:
function toDigits(number) {
var left;
var results = [];
while (true) {
left = number % 10;
results.unshift(left);
number = (number - left) / 10;
if (number === 0) {
break;
}
}
return results;
}
If you can use some dynamic query, you can use LEN
. It will give false on both empty and null string. By this way you can implement the option parameter.
ALTER PROCEDURE [dbo].[psProducts]
(@SearchType varchar(50))
AS
BEGIN
SET NOCOUNT ON;
DECLARE @Query nvarchar(max) = N'
SELECT
P.[ProductId],
P.[ProductName],
P.[ProductPrice],
P.[Type]
FROM [Product] P'
-- if @Searchtype is not null then use the where clause
SET @Query = CASE WHEN LEN(@SearchType) > 0 THEN @Query + ' WHERE p.[Type] = ' + ''''+ @SearchType + '''' ELSE @Query END
EXECUTE sp_executesql @Query
PRINT @Query
END
For those who may find this later, after .NET version 4.6, I was running into this problem as well.
Make sure that you check your web.config file for the following lines:
<compilation debug="true" targetFramework="4.5">
...
<httpRuntime targetFramework="4.5" />
If you are running 4.6.x or a higher version of .NET on the server, make sure you adjust these targetFramework values to match the version of the framework on your server. If your versions read less than 4.6.x, then I would recommend you upgrade .NET and use the newer version unless your code is dependent on an older version (which, in that case, you should consider updating it).
I changed the targetFrameworks to 4.7.2 and the problem disappeared:
<compilation debug="true" targetFramework="4.7.2">
...
<httpRuntime targetFramework="4.7.2" />
The newer frameworks sort this issue out by using the best protocol available and blocking insecure or obsolete ones. If the remote service you are trying to connect to or call is giving this error, it could be that they don't support the old protocols anymore.
I would suggest you using Charles Proxy app on Mac
It allows you using Bandwidth Throttle
feature that was created just for adjusting network connection
Star/Stop Throttling ? command + T
Throttle Settings... ? command + T + ? shift
*If you create you own Preset via Add Preset
with Bandwidth 0 and 0 for Download and upload you can simulate no Internet connection. Also it is very useful to enable it only for some specific hosts
As an alternative you can disable your connection on Mac because all traffic from Simulator go thought your computer

You could use np.isreal

Out[11]:
a b
item
a True True

e True

So to get the subDataFrame of rouges, (Note: the negation, ~, of the above finds the ones which have at least one rogue non-numeric):
In [13]: df[~df.applymap(np.isreal).all(1)]
Out[13]:
a b
item
d bad 0.4
You could also find the location of the first offender you could use argmin:
In [14]: np.argmin(df.applymap(np.isreal).all(1))
Out[14]: 'd'
As @CTZhu points out, it may be slightly faster to check whether it's an instance of either int or float (there is some additional overhead with np.isreal):
df.applymap(lambda x: isinstance(x, (int, float)))
year(@date)
year(getdate())
year('20120101')
update table
set column = year(date_column)
whre ....
or if you need it in another table
update t
set column = year(t1.date_column)
from table_source t1
join table_target t on (join condition)
where ....

/* Extend jQuery with functions for PUT and DELETE requests. */
function _ajax_request(url, data, callback, type, method) {
if (jQuery.isFunction(data)) {

It actually requires inclusion of Twitter Bootstrap's dropdown.js

[tableView setSeparatorInset:UIEdgeInsetsMake(0, 0, 0, 0)];
You can set the 'Separator Inset' from the storyboard:
The other posters are correct you cannot connect to MySQL directly from javascript. This is because JavaScript is at client side & mysql is server side.
So your best bet is to use ajax to call a handler as quoted above if you can let us know what language your project is in we can better help you ie php/java/.net
If you project is using php then the example from Merlyn is a good place to start, I would personally use jquery.ajax() to cut down you code and have a better chance of less cross browser issues.

You could try something like this (see also Tutorial - All about VDIs: How can I resize the partitions inside my VDI?):
Copy contents from old to new disk. This will take a fair amount of time. (Here /dev/hdX is your original disk and /dev/hdY the new one).
dd if=/dev/hdX of=/dev/hdY
Warning: Make sure you do not mix up your input and output disks or you'll wipe all information from your original disk! (if= specifies the input and of= specifies the output.)
Once you've verified the larger VDI boots Windows fine (and disk size is as you'd expect) you can of course delete the old smaller VDI.
Edit: Instead of rebooting before you resize the partition you should be able to run partprobe and the hit CTRL+R in GParted instead.
If you're page has an Open Graph image, commonly used for social sharing, you can use it to set the background image at runtime with vanilla JavaScript like so:
<script>
const meta = document.querySelector('[property="og:image"]');
const body = document.querySelector("body");
body.style.background = `url(${meta.content})`;
</script>
The above uses document.querySelector
and Attribute Selectors to assign meta
the first Open Graph image it selects. A similar task is performed to get the body
. Finally, string interpolation is used to assign body
the background.style
the value of the path to the Open Graph image.
If you want the image to cover the entire viewport and stay fixed set background-size
like so:
body.style.background = `url(${meta.content}) center center no-repeat fixed`;
body.style.backgroundSize = 'cover';
Using this approach you can set a low-quality background image placeholder using CSS and swap with a high-fidelity image later using an image onload
event, thereby reducing perceived latency.
If you have a plugin within the browser which knows how to open a PDF file it will open directly. Like in case of images and HTML content.
So the alternative approach is not to send your MIME type in the response. In this way the browser will never know which plugin should open it. Hence it will give you a Save/Open dialog box.
If you need access to the resources of a library project (as you do with ABS) ensure that you add the library project/module as a "Module Dependency" instead of a "Library".
Use modulo
whenever a number x is a multiple of some number y, then always x % y equal to 0, which can be used as a check. So use
if (j % 4 == 0)
Also with dict
a = []
b = {1:'one'}
a.append(dict(b))
print a
b[1]='iuqsdgf'
print a
result
[{1: 'one'}]
[{1: 'one'}]
Purpose of these interfaces from oracle documentation :
Runnable interface should be implemented by any class whose instances are intended to be executed by a Thread
. The class must define a method of no arguments called run
.
Callable: A task that returns a result and may throw an exception. Implementors define a single method with no arguments called call.
The Callable
interface is similar to Runnable
, in that both are designed for classes whose instances are potentially executed by another thread. A Runnable
, however, does not return a result and cannot throw a checked exception.
Other differences:
You can pass Runnable
to create a Thread. But you can't create new Thread by passing Callable
as parameter. You can pass Callable only to ExecutorService
instances.
public class HelloRunnable implements Runnable {
public void run() {
System.out.println("Hello from a thread!");
}
public static void main(String args[]) {
(new Thread(new HelloRunnable())).start();
}
}
Use Runnable
for fire and forget calls. Use Callable
to verify the result.
Callable
can be passed to invokeAll method unlike Runnable
. Methods invokeAny
and invokeAll
perform the most commonly useful forms of bulk execution, executing a collection of tasks and then waiting for at least one, or all, to complete
Trivial difference : method name to be implemented => run()
for Runnable
and call()
for Callable
.
With EF or LINQ to SQL:
var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();
With LINQ to Objects I suggest to use morelinq extension MaxBy
(get morelinq from nuget):
var item = items.MaxBy(i => i.Value);
I used a hidden checkbox to persistent view of some message. The checkbox could be hidden (display:none) or not. This is a tiny code that I could write.
You can see and test the demo on JSFiddle
HTML:
<input type=checkbox id="show">
<label for="show">Help?</label>
<span id="content">Do you need some help?</span>
CSS:
#show,#content{display:none;}
#show:checked~#content{display:block;}
Run code snippet:
#show,#content{display:none;}_x000D_
#show:checked~#content{display:block;}
_x000D_
<input id="show" type=checkbox>_x000D_
<label for="show">Click for Help</label>_x000D_
<span id="content">Do you need some help?</span>

Just a remark about your saying
Hi, I tried searching a way to insert information in multiple tables in the same query
Do you eat all your lunch dishes mixed with drinks in the same bowl?
I suppose - no.
Same here.
There are things we do separately.
2 insert queries are 2 insert queries. It's all right. Nothing wrong with it. No need to mash it in one.
Same for select. Query must be sensible and do it's job. That's the only reasons. Number of queries is not.
As for the transactions - you may use them, but it's not THAT big deal for the average web-site. If it happened once a year (if ever) that one user registration being broken you'll be able to fix, no doubt.
there are hundreds of thousands sites running mysql with no transaction support driver. Have you heard of terrible disasters breaking these sites apart? Me neither.
And mysql_insert_id() has noting to do with transactions. you may include in into transaction all right. it's just different matters. Someone raised this question out of nowhere.
From the javadoc of java.rmi.registry.Registry
Therefore, a registry's remote object implementation is typically exported with a well-known address, such as with a well-known
ObjID
and TCP port number (default is1099
).
See more in the javadoc of java.rmi.registry.LocateRegistry
.
I personally prefer using char(1) with values 'Y' and 'N' for databases that don't have a native type for boolean. Letters are more user frendly than numbers which assume that those reading it will now that 1 corresponds to true and 0 corresponds to false.
'Y' and 'N' also maps nicely when using (N)Hibernate.
Do you have a bean declared in your context file that has an id of "articleService"? I believe that autowiring matches the id of a bean in your context files with the variable name that you are attempting to Autowire.

Self executing function are used to manage the scope of a Variable.
The scope of a variable is the region of your program in which it is defined.
A global variable has global scope; it is defined everywhere in your JavaScript code and can be accessed from anywhere within the script, even in your functions. On the other hand, variables declared within a function are defined only within the body of the function. They are local variables, have local scope and can only be accessed within that function. Function parameters also count as local variables and are defined only within the body of the function.
As shown below, you can access the global variables variable inside your function and also note that within the body of a function, a local variable takes precedence over a global variable with the same name.
var globalvar = "globalvar"; // this var can be accessed anywhere within the script
function scope() {
alert(globalvar);
var localvar = "localvar"; //can only be accessed within the function scope
}
scope();
So basically a self executing function allows code to be written without concern of how variables are named in other blocks of javascript code.
Using data-parent
, first solution is to stick to the example selector architecture
<div id="myGroup">
<button class="btn dropdown" data-toggle="collapse" data-target="#keys" data-parent="#myGroup"><i class="icon-chevron-right"></i> Keys <span class="badge badge-info pull-right">X</span></button>
<button class="btn dropdown" data-toggle="collapse" data-target="#attrs" data-parent="#myGroup"><i class="icon-chevron-right"></i> Attributes</button>
<button class="btn dropdown" data-toggle="collapse" data-target="#edit" data-parent="#myGroup"><i class="icon-chevron-right"></i> Edit Details</button>
<div class="accordion-group">
<div class="collapse indent" id="keys">
keys
</div>
<div class="collapse indent" id="attrs">
attrs
</div>
<div class="collapse" id="edit">
edit
</div>
</div>
</div>
Second solution is to bind on the events and hide the other collapsible elements yourself.
var $myGroup = $('#myGroup');
$myGroup.on('show.bs.collapse','.collapse', function() {
$myGroup.find('.collapse.in').collapse('hide');
});
PS: the strange effect in the demos is caused by the min-height
set for the example, just ignore that.
Edit: changed the JS event from show
to show.bs.collapse
as specified in Bootstrap documentation.
This code works just fine:
ViewModel.cs:
public ICommand WindowClosing
{
get
{
return new RelayCommand<CancelEventArgs>(
(args) =>{
});
}
}
and in XAML:
<i:Interaction.Triggers>
<i:EventTrigger EventName="Closing">
<command:EventToCommand Command="{Binding WindowClosing}" PassEventArgsToCommand="True" />
</i:EventTrigger>
</i:Interaction.Triggers>
assuming that:
DataContext
of the main container.xmlns:command="clr-namespace:GalaSoft.MvvmLight.Command;assembly=GalaSoft.MvvmLight.Extras.SL5"
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
Login as sys user in sql*plus. Then do this query:
select * from v$version;
or
select * from product_component_version;
You can also do it by checking if View's indexOfView method if indexOfView method returns -1 then we can use.
ViewGroup's detachViewFromParent(v); followed by ViewGroup's removeDetachedView(v, true/false);
If you use the FIND_IN_SET
function:
FIND_IN_SET(a, columnname)
yields all the records that have "a" in them, alone or with others
AND
FIND_IN_SET(columnname, a)
yields only the records that have "a" in them alone, NOT the ones with the others
So if record1 is (a,b,c) and record2 is (a)
FIND_IN_SET(columnname, a)
yields only record2 whereas FIND_IN_SET(a, columnname)
yields both records.
As a general rule, when on Debian or Ubuntu and you're missing a development file (or any other file for that matter), use apt-file
to figure out which package provides that file:
~ apt-file search openssl/bio.h
android-libboringssl-dev: /usr/include/android/openssl/bio.h
libssl-dev: /usr/include/openssl/bio.h
libwolfssl-dev: /usr/include/cyassl/openssl/bio.h
libwolfssl-dev: /usr/include/wolfssl/openssl/bio.h
A quick glance at each of the packages that are returned by the command, using apt show
will tell you which among the packages is the one you're looking for:
~ apt show libssl-dev

You Can Use FORMAT if you column is a number Syntax like
FORMAT ( value, format [, culture ] ) In use like
FORMAT ( @d, 'D', 'en-US' )
or FORMAT(123456789,'###-##-####')
(But This works for only SQL SERVER 2012 And After)
In Use Like
UPDATE TABLE_NAME SET COLUMN_NAME = FORMAT(COLUMN_NAME ,'###-##-####')
And
if your column is Varchar Or Nvarchar use do like this
CONCAT(SUBSTRING(CELLPHONE,0,4),' ',SUBSTRING(CELLPHONE,4,3),'
',SUBSTRING(CELLPHONE,7,2) ,' ',SUBSTRING(CELLPHONE,9,2) )

There are multiple aspects to argument overloading in Javascript:
Variable arguments - You can pass different sets of arguments (in both type and quantity) and the function will behave in a way that matches the arguments passed to it.
Default arguments - You can define a default value for an argument if it is not passed.
Named arguments - Argument order becomes irrelevant and you just name which arguments you want to pass to the function.
Below is a section on each of these categories of argument handling.
Because javascript has no type checking on arguments or required qty of arguments, you can just have one implementation of myFunc()
that can adapt to what arguments were passed to it by checking the type, presence or quantity of arguments.
jQuery does this all the time. You can make some of the arguments optional or you can branch in your function depending upon what arguments are passed to it.
In implementing these types of overloads, you have several different techniques you can use:
undefined
.arguments.length
.arguments
pseudo-array to access any given argument with arguments[i]
.Here are some examples:
Let's look at jQuery's obj.data()
method. It supports four different forms of usage:
obj.data("key");
obj.data("key", value);
obj.data();
obj.data(object);
Each one triggers a different behavior and, without using this dynamic form of overloading, would require four separate functions.
Here's how one can discern between all these options in English and then I'll combine them all in code:
// get the data element associated with a particular key value
obj.data("key");
If the first argument passed to .data()
is a string and the second argument is undefined
, then the caller must be using this form.
// set the value associated with a particular key
obj.data("key", value);
If the second argument is not undefined, then set the value of a particular key.
// get all keys/values
obj.data();
If no arguments are passed, then return all keys/values in a returned object.
// set all keys/values from the passed in object
obj.data(object);
If the type of the first argument is a plain object, then set all keys/values from that object.
Here's how you could combine all of those in one set of javascript logic:
// method declaration for .data()
data: function(key, value) {
if (arguments.length === 0) {
// .data()
// no args passed, return all keys/values in an object
} else if (typeof key === "string") {
// first arg is a string, look at type of second arg
if (typeof value !== "undefined") {
// .data("key", value)
// set the value for a particular key
} else {
// .data("key")
// retrieve a value for a key
}
} else if (typeof key === "object") {
// .data(object)
// set all key/value pairs from this object
} else {
// unsupported arguments passed
}
},
The key to this technique is to make sure that all forms of arguments you want to accept are uniquely identifiable and there is never any confusion about which form the caller is using. This generally requires ordering the arguments appropriately and making sure that there is enough uniqueness in the type and position of the arguments that you can always tell which form is being used.
For example, if you have a function that takes three string arguments:
obj.query("firstArg", "secondArg", "thirdArg");
You can easily make the third argument optional and you can easily detect that condition, but you cannot make only the second argument optional because you can't tell which of these the caller means to be passing because there is no way to identify if the second argument is meant to be the second argument or the second argument was omitted so what's in the second argument's spot is actually the third argument:
obj.query("firstArg", "secondArg");
obj.query("firstArg", "thirdArg");
Since all three arguments are the same type, you can't tell the difference between different arguments so you don't know what the caller intended. With this calling style, only the third argument can be optional. If you wanted to omit the second argument, it would have to be passed as null
(or some other detectable value) instead and your code would detect that:
obj.query("firstArg", null, "thirdArg");
Here's a jQuery example of optional arguments. both arguments are optional and take on default values if not passed:
clone: function( dataAndEvents, deepDataAndEvents ) {
dataAndEvents = dataAndEvents == null ? false : dataAndEvents;
deepDataAndEvents = deepDataAndEvents == null ? dataAndEvents : deepDataAndEvents;
return this.map( function () {
return jQuery.clone( this, dataAndEvents, deepDataAndEvents );
});
},
Here's a jQuery example where the argument can be missing or any one of three different types which gives you four different overloads:
html: function( value ) {
if ( value === undefined ) {
return this[0] && this[0].nodeType === 1 ?
this[0].innerHTML.replace(rinlinejQuery, "") :
null;
// See if we can take a shortcut and just use innerHTML
} else if ( typeof value === "string" && !rnoInnerhtml.test( value ) &&
(jQuery.support.leadingWhitespace || !rleadingWhitespace.test( value )) &&
!wrapMap[ (rtagName.exec( value ) || ["", ""])[1].toLowerCase() ] ) {
value = value.replace(rxhtmlTag, "<$1></$2>");
try {
for ( var i = 0, l = this.length; i < l; i++ ) {
// Remove element nodes and prevent memory leaks
if ( this[i].nodeType === 1 ) {
jQuery.cleanData( this[i].getElementsByTagName("*") );
this[i].innerHTML = value;
}
}
// If using innerHTML throws an exception, use the fallback method
} catch(e) {
this.empty().append( value );
}
} else if ( jQuery.isFunction( value ) ) {
this.each(function(i){
var self = jQuery( this );
self.html( value.call(this, i, self.html()) );
});
} else {
this.empty().append( value );
}
return this;
},
Other languages (like Python) allow one to pass named arguments as a means of passing only some arguments and making the arguments independent of the order they are passed in. Javascript does not directly support the feature of named arguments. A design pattern that is commonly used in its place is to pass a map of properties/values. This can be done by passing an object with properties and values or in ES6 and above, you could actually pass a Map object itself.
Here's a simple ES5 example:
jQuery's $.ajax()
accepts a form of usage where you just pass it a single parameter which is a regular Javascript object with properties and values. Which properties you pass it determine which arguments/options are being passed to the ajax call. Some may be required, many are optional. Since they are properties on an object, there is no specific order. In fact, there are more than 30 different properties that can be passed on that object, only one (the url) is required.
Here's an example:
$.ajax({url: "http://www.example.com/somepath", data: myArgs, dataType: "json"}).then(function(result) {
// process result here
});
Inside of the $.ajax()
implementation, it can then just interrogate which properties were passed on the incoming object and use those as named arguments. This can be done either with for (prop in obj)
or by getting all the properties into an array with Object.keys(obj)
and then iterating that array.
This technique is used very commonly in Javascript when there are large numbers of arguments and/or many arguments are optional. Note: this puts an onus on the implementating function to make sure that a minimal valid set of arguments is present and to give the caller some debug feedback what is missing if insufficient arguments are passed (probably by throwing an exception with a helpful error message).
In an ES6 environment, it is possible to use destructuring to create default properties/values for the above passed object. This is discussed in more detail in this reference article.
Here's one example from that article:
function selectEntries({ start=0, end=-1, step=1 } = {}) {
···
};
This creates default properties and values for the start
, end
and step
properties on an object passed to the selectEntries()
function.
In ES6, Javascript adds built-in language support for default values for arguments.
For example:
function multiply(a, b = 1) {
return a*b;
}
multiply(5); // 5

Yeah you can do some tricky works to simulate what you want:
1) Call your controller from a view by ajax. 2) Return your View
3) Use something like the following in the success
(or maybe error
! error works for me!) section of your $.ajax request:
$("#imgPrint").click(function () {
$.ajax({
url: ...,
type: 'POST', dataType: 'json',
data: $("#frm").serialize(),
success: function (data, textStatus, jqXHR) {
//Here it is:
//Gets the model state
var isValid = '@Html.Raw(Json.Encode(ViewData.ModelState.IsValid))';
// checks that model is valid
if (isValid == 'true') {
//open new tab or window - according to configs of browser
var w = window.open();
//put what controller gave in the new tab or win
$(w.document.body).html(jqXHR.responseText);
}
$("#imgSpinner1").hide();
},
error: function (jqXHR, textStatus, errorThrown) {
// And here it is for error section.
//Pay attention to different order of
//parameters of success and error sections!
var isValid = '@Html.Raw(Json.Encode(ViewData.ModelState.IsValid))';
if (isValid == 'true') {
var w = window.open();
$(w.document.body).html(jqXHR.responseText);
}
$("#imgSpinner1").hide();
},
beforeSend: function () { $("#imgSpinner1").show(); },
complete: function () { $("#imgSpinner1").hide(); }
});
});
The variable $_POST
is automatically populated.
Try var_dump($_POST);
to see the contents.
You can access individual values like this: echo $_POST["name"];
This, of course, assumes your form is using the typical form encoding (i.e. enctype=”multipart/form-data”
If your post data is in another format (e.g. JSON or XML, you can do something like this:
$post = file_get_contents('php://input');
and $post
will contain the raw data.
Assuming you're using the standard $_POST
variable, you can test if a checkbox is checked like this:
if(isset($_POST['myCheckbox']) && $_POST['myCheckbox'] == 'Yes')
{
...
}
If you have an array of checkboxes (e.g.
<form action="myscript.php" method="post">
<input type="checkbox" name="myCheckbox[]" value="A" />val1<br />
<input type="checkbox" name="myCheckbox[]" value="B" />val2<br />
<input type="checkbox" name="myCheckbox[]" value="C" />val3<br />
<input type="checkbox" name="myCheckbox[]" value="D" />val4<br />
<input type="checkbox" name="myCheckbox[]" value="E" />val5
<input type="submit" name="Submit" value="Submit" />
</form>
Using [ ]
in the checkbox name indicates that the selected values will be accessed by PHP script as an array. In this case $_POST['myCheckbox']
won't return a single string but will return an array consisting of all the values of the checkboxes that were checked.
For instance, if I checked all the boxes, $_POST['myCheckbox']
would be an array consisting of: {A, B, C, D, E}
. Here's an example of how to retrieve the array of values and display them:
$myboxes = $_POST['myCheckbox'];
if(empty($myboxes))
{
echo("You didn't select any boxes.");
}
else
{
$i = count($myboxes);
echo("You selected $i box(es): <br>");
for($j = 0; $j < $i; $j++)
{
echo $myboxes[$j] . "<br>";
}
}
There are three ways to do this, depending on your needs. You could use the old-school C way and call fopen/fread/fclose, or you could use the C++ fstream facilities (ifstream/ofstream), or if you're using MFC, use the CFile class, which provides functions to accomplish actual file operations.
All of these are suitable for both text and binary, though none have a specific readline functionality. What you'd most likely do instead in that case is use the fstream classes (fstream.h) and use the stream operators (<< and >>) or the read function to read/write blocks of text:
int nsize = 10;
char *somedata;
ifstream myfile;
myfile.open("<path to file>");
myfile.read(somedata,nsize);
myfile.close();
Note that, if you're using Visual Studio 2005 or higher, traditional fstream may not be available (there's a new Microsoft implementation, which is slightly different, but accomplishes the same thing).
Maybe you want unpack elements of array, I don't know if I got it, but below a example:
def my_func(*args):
for a in args:
print a
my_func(*[1,2,3,4])
my_list = ['a','b','c']
my_func(*my_list)
Below code gives a basic idea. This is not best solution though.
public static String splitJoin(String sourceStr, String delim,boolean trim,boolean ignoreEmpty){
return join(Arrays.asList(sourceStr.split(delim)), delim, ignoreEmpty);
}
public static String join(List<?> list, String delim, boolean ignoreEmpty) {
int len = list.size();
if (len == 0)
return "";
StringBuilder sb = new StringBuilder(list.get(0).toString());
for (int i = 1; i < len; i++) {
if (ignoreEmpty && !StringUtils.isBlank(list.get(i).toString())) {
sb.append(delim);
sb.append(list.get(i).toString().trim());
}
}
return sb.toString();
}
I installed the Role plugin under Jenkins-3.5, but it does not show the "Manage Roles" option under "Manage Jenkins", and when one follows the security install page from the wiki, all users are locked out instantly. I had to manually shutdown Jenkins on the server, restore the correct configuration settings (/me is happy to do proper backups) and restart Jenkins.
I didn't have high hopes, as that plugin was last updated in 2011
This can be done MUCH easier using wonderful XStream library. No wrappers, no annotations.
<Strings>
<String>a</String>
<String>b</String>
</Strings>
(String
alias can be avoided by using lowercase string
tag, but I used OP's code)
List <String> list = new ArrayList <String>();
list.add("a");
list.add("b");
XStream xStream = new XStream();
xStream.alias("Strings", List.class);
xStream.alias("String", String.class);
String result = xStream.toXML(list);
Deserialization into ArrayList
XStream xStream = new XStream();
xStream.alias("Strings", ArrayList.class);
xStream.alias("String", String.class);
xStream.addImplicitArray(ArrayList.class, "elementData");
List <String> result = (List <String>)xStream.fromXML(file);
Deserialization into String[]
XStream xStream = new XStream();
xStream.alias("Strings", String[].class);
xStream.alias("String", String.class);
String[] result = (String[])xStream.fromXML(file);
Note, that XStream instance is thread-safe and can be pre-configured, shrinking code amount to one-liners.
XStream can also be used as a default serialization mechanism for JAX-RS service. Example of plugging XStream in Jersey can be found here
Alternatively, I would suggest turning interactive on in the beginning and at the very last plot, turn it off. All will show up, but they will not disappear as your program will stay around until you close the figures.
import matplotlib.pyplot as plt
from matplotlib import interactive
plt.figure(1)
... code to make figure (1)
interactive(True)
plt.show()
plt.figure(2)
... code to make figure (2)
plt.show()
plt.figure(3)
... code to make figure (3)
interactive(False)
plt.show()
Note that you can also expand part of argument list:
myfun(1, *("foo", "bar"))
Use the code below. It works every time.
<button onclick="self.close()">Close</button>
It works every time in Chrome and also works on Firefox.
I have created a sample UI which shows the save and open file dialog. Click on save button to open save dialog and click on open button to open file dialog.

i saw following in a book:
this.setState(state => state.someProperty.falg = false);
but i'm not sure if it's right..

It's as simple as:
if (value.compareTo(BigDecimal.ZERO) > 0)
The documentation for compareTo
actually specifies that it will return -1, 0 or 1, but the more general Comparable<T>.compareTo
method only guarantees less than zero, zero, or greater than zero for the appropriate three cases - so I typically just stick to that comparison.
With ES6: This is now part of the language:
function myFunc(a, b = 0) {
// function body
}
Please keep in mind that ES6 checks the values against undefined
and not against truthy-ness (so only real undefined values get the default value - falsy values like null will not default).
With ES5:
function myFunc(a,b) {
b = b || 0;
// b will be set either to b or to 0.
}
This works as long as all values you explicitly pass in are truthy.
Values that are not truthy as per MiniGod's comment: null, undefined, 0, false, ''
It's pretty common to see JavaScript libraries to do a bunch of checks on optional inputs before the function actually starts.
The
linecache
module allows one to get any line from a Python source file, while attempting to optimize internally, using a cache, the common case where many lines are read from a single file. This is used by thetraceback
module to retrieve source lines for inclusion in the formatted traceback...
What it seems like to me is that by calling the keys method you're returning to python a dictionary object when it's looking for a list or a tuple. So try taking all of the keys in the dictionary, putting them into a list and then using the for loop.
I just developed a javascript library called JIC to solve that problem. It allows you to compress jpg and png on the client side 100% with javascript and no external libraries required!
You can try the demo here : http://makeitsolutions.com/labs/jic and get the sources here : https://github.com/brunobar79/J-I-C
I would do this:
function randomInt(min, max) {
return Math.round(min + Math.random()*(max-min));
}
var index = {}, numbers = [];
for (var i=0; i<8; ++i) {
var number;
do {
number = randomInt(1, 100);
} while (index.hasOwnProperty("_"+number));
index["_"+number] = true;
numbers.push(number);
}
delete index;
Try the following, none of the above solved it for me
Select "Run as administrator"
Then click on the big left box next to Apache
And Choose to uninstall Apache
I have no idea why this worked but it solved my problem directly!
Whenever you want to extend the properties of User.Identity with any additional properties like the question above, add these properties to the ApplicationUser class first like so:
public class ApplicationUser : IdentityUser
{
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
return userIdentity;
}
// Your Extended Properties
public long? OrganizationId { get; set; }
}
Then what you need is to create an extension method like so (I create mine in an new Extensions folder):
namespace App.Extensions
{
public static class IdentityExtensions
{
public static string GetOrganizationId(this IIdentity identity)
{
var claim = ((ClaimsIdentity)identity).FindFirst("OrganizationId");
// Test for null to avoid issues during local testing
return (claim != null) ? claim.Value : string.Empty;
}
}
}
When you create the Identity in the ApplicationUser class, just add the Claim -> OrganizationId like so:
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here => this.OrganizationId is a value stored in database against the user
userIdentity.AddClaim(new Claim("OrganizationId", this.OrganizationId.ToString()));
return userIdentity;
}
Once you added the claim and have your extension method in place, to make it available as a property on your User.Identity, add a using statement on the page/file you want to access it:
in my case: using App.Extensions;
within a Controller and @using. App.Extensions
withing a .cshtml View file.
EDIT:
What you can also do to avoid adding a using statement in every View is to go to the Views folder, and locate the Web.config file in there.
Now look for the <namespaces>
tag and add your extension namespace there like so:
<add namespace="App.Extensions" />
Save your file and you're done. Now every View will know of your extensions.
You can access the Extension Method:
var orgId = User.Identity.GetOrganizationId();
OO Abstraction occurs during class level design, with the objective of hiding the implementation complexity of how the the features offered by an API / design / system were implemented, in a sense simplifying the 'interface' to access the underlying implementation.
The process of abstraction can be repeated at increasingly 'higher' levels (layers) of classes, which enables large systems to be built without increasing the complexity of code and understanding at each layer.
For example, a Java developer can make use of the high level features of FileInputStream without concern for how it works (i.e. file handles, file system security checks, memory allocation and buffering will be managed internally, and are hidden from consumers). This allows the implementation of FileInputStream
to be changed, and as long as the API (interface) to FileInputStream
remains consistent, code built against previous versions will still work.
Similarly, when designing your own classes, you will want to hide internal implementation details from others as far as possible.
In the Booch definition1, OO Encapsulation is achieved through Information Hiding, and specifically around hiding internal data (fields / members representing the state) owned by a class instance, by enforcing access to the internal data in a controlled manner, and preventing direct, external change to these fields, as well as hiding any internal implementation methods of the class (e.g. by making them private).
For example, the fields of a class can be made private
by default, and only if external access to these was required, would a get()
and/or set()
(or Property
) be exposed from the class. (In modern day OO languages, fields can be marked as readonly
/ final
/ immutable
which further restricts change, even within the class).
Example where NO information hiding has been applied (Bad Practice):
class Foo {
// BAD - NOT Encapsulated - code external to the class can change this field directly
// Class Foo has no control over the range of values which could be set.
public int notEncapsulated;
}
Example where field encapsulation has been applied:
class Bar {
// Improvement - access restricted only to this class
private int encapsulatedPercentageField;
// The state of Bar (and its fields) can now be changed in a controlled manner
public void setEncapsulatedField(int percentageValue) {
if (percentageValue >= 0 && percentageValue <= 100) {
encapsulatedPercentageField = percentageValue;
}
// else throw ... out of range
}
}
Example of immutable / constructor-only initialization of a field:
class Baz {
private final int immutableField;
public void Baz(int onlyValue) {
// ... As above, can also check that onlyValue is valid
immutableField = onlyValue;
}
// Further change of `immutableField` outside of the constructor is NOT permitted, even within the same class
}
Re : Abstraction vs Abstract Class
Abstract classes are classes which promote reuse of commonality between classes, but which themselves cannot directly be instantiated with new()
- abstract classes must be subclassed, and only concrete
(non abstract) subclasses may be instantiated. Possibly one source of confusion between Abstraction
and an abstract class
was that in the early days of OO, inheritance was more heavily used to achieve code reuse (e.g. with associated abstract base classes). Nowadays, composition is generally favoured over inheritance, and there are more tools available to achieve abstraction, such as through Interfaces, events / delegates / functions, traits / mixins etc.
Re : Encapsulation vs Information Hiding
The meaning of encapsulation appears to have evolved over time, and in recent times, encapsulation
can commonly also used in a more general sense when determining which methods, fields, properties, events etc to bundle into a class.
Quoting Wikipedia:
In the more concrete setting of an object-oriented programming language, the notion is used to mean either an information hiding mechanism, a bundling mechanism, or the combination of the two.
For example, in the statement
I've encapsulated the data access code into its own class
.. the interpretation of encapsulation is roughly equivalent to the Separation of Concerns or the Single Responsibility Principal (the "S" in SOLID), and could arguably be used as a synonym for refactoring.
[1] Once you've seen Booch's encapsulation cat picture you'll never be able to forget encapsulation - p46 of Object Oriented Analysis and Design with Applications, 2nd Ed
For question #1, let's break it into two parts. First, increment any document that has "items.item_name" equal to "my_item_two". For this you'll have to use the positional "$" operator. Something like:
db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } ,
{$inc : {"items.$.price" : 1} } ,
false ,
true);
Note that this will only increment the first matched subdocument in any array (so if you have another document in the array with "item_name" equal to "my_item_two", it won't get incremented). But this might be what you want.
The second part is trickier. We can push a new item to an array without a "my_item_two" as follows:
db.bar.update( {user_id : 123456, "items.item_name" : {$ne : "my_item_two" }} ,
{$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
false ,
true);
For your question #2, the answer is easier. To increment the total and the price of item_three in any document that contains "my_item_three," you can use the $inc operator on multiple fields at the same time. Something like:
db.bar.update( {"items.item_name" : {$ne : "my_item_three" }} ,
{$inc : {total : 1 , "items.$.price" : 1}} ,
false ,
true);
You have the wrong URL.
I don't know what you mean by "JDBC 2005". When I looked on the microsoft site, I found something called the Microsoft SQL Server JDBC Driver 2.0. You're going to want that one - it includes lots of fixes and some perf improvements. [edit: you're probably going to want the latest driver. As of March 2012, the latest JDBC driver from Microsoft is JDBC 4.0]
Check the release notes. For this driver, you want:
URL: jdbc:sqlserver://server:port;DatabaseName=dbname
Class name: com.microsoft.sqlserver.jdbc.SQLServerDriver
It seems you have the class name correct, but the URL wrong.
Microsoft changed the class name and the URL after its initial release of a JDBC driver. The URL you are using goes with the original JDBC driver from Microsoft, the one MS calls the "SQL Server 2000 version". But that driver uses a different classname.
For all subsequent drivers, the URL changed to the form I have here.
This is in the release notes for the JDBC driver.
Sometimes, especially after generating a new certificate or starting to use a new code signing identity, there seems to be no other way to fix this, other than doing some cleaning the .pbxproj file. This is probably a bug that will be fixed, so if you are reading this long after this post, maybe you should try some other solution.
There is an excellent post about this in the pixeldock blog: http://www.pixeldock.com/blog/code-sign-error-provisioning-profile-cant-be-found/
In short, mostly quoting from that article, you need to:
Good luck!
Do it like this:
char s[256];
strcpy(s, "one two three");
char* token = strtok(s, " ");
while (token) {
printf("token: %s\n", token);
token = strtok(NULL, " ");
}
Note: strtok
modifies the string its tokenising, so it cannot be a const char*
.
A new list is created but the items in it are references to the orginal items (just like in the original list). Changes to the list itself are independent, but to the items will find the change in both lists.
This fiddle has both each
and direct json. http://jsfiddle.net/streethawk707/a9ssja22/.
Below are the two ways of iterating over array. One is with direct json passing and another is naming the json array while passing to content holder.
Eg1: The below example is directly calling json key (data) inside small_data variable.
In html use the below code:
<div id="small-content-placeholder"></div>
The below can be placed in header or body of html:
<script id="small-template" type="text/x-handlebars-template">
<table>
<thead>
<th>Username</th>
<th>email</th>
</thead>
<tbody>
{{#data}}
<tr>
<td>{{username}}
</td>
<td>{{email}}</td>
</tr>
{{/data}}
</tbody>
</table>
</script>
The below one is on document ready:
var small_source = $("#small-template").html();
var small_template = Handlebars.compile(small_source);
The below is the json:
var small_data = {
data: [
{username: "alan1", firstName: "Alan", lastName: "Johnson", email: "[email protected]" },
{username: "alan2", firstName: "Alan", lastName: "Johnson", email: "[email protected]" }
]
};
Finally attach the json to content holder:
$("#small-content-placeholder").html(small_template(small_data));
Eg2: Iteration using each.
Consider the below json.
var big_data = [
{
name: "users1",
details: [
{username: "alan1", firstName: "Alan", lastName: "Johnson", email: "[email protected]" },
{username: "allison1", firstName: "Allison", lastName: "House", email: "[email protected]" },
{username: "ryan1", firstName: "Ryan", lastName: "Carson", email: "[email protected]" }
]
},
{
name: "users2",
details: [
{username: "alan2", firstName: "Alan", lastName: "Johnson", email: "[email protected]" },
{username: "allison2", firstName: "Allison", lastName: "House", email: "[email protected]" },
{username: "ryan2", firstName: "Ryan", lastName: "Carson", email: "[email protected]" }
]
}
];
While passing the json to content holder just name it in this way:
$("#big-content-placeholder").html(big_template({big_data:big_data}));
And the template looks like :
<script id="big-template" type="text/x-handlebars-template">
<table>
<thead>
<th>Username</th>
<th>email</th>
</thead>
<tbody>
{{#each big_data}}
<tr>
<td>{{name}}
<ul>
{{#details}}
<li>{{username}}</li>
<li>{{email}}</li>
{{/details}}
</ul>
</td>
<td>{{email}}</td>
</tr>
{{/each}}
</tbody>
</table>
</script>
You need to install the pgsql module for php. In debian/ubuntu is something like this:
sudo apt-get install php5-pgsql
Or if the package is installed, you need to enable de module in php.ini
extension=php_pgsql.dll (windows)
extension=php_pgsql.so (linux)
