To create icon you can use Glyphicon in Bootstrap:
<a href="#" class="btn btn-info btn-sm">
<span class="glyphicon glyphicon-menu-hamburger"></span>
</a>
And then control size of icon in css:
.glyphicon-menu-hamburger {
font-size: npx;
}
RHT pretty much has it. Or you could use a RowSetDynaClass and let someone else do all the work :)
for example, if you want to close a windows form when an action is performed there are two methods to do it
1.To close it directly
Form1 f=new Form1();
f.close(); //u can use below comment also
//this.close();
2.We can also hide form without closing it
private void button1_Click(object sender, EventArgs e)
{
Form1 f1 = new Form1();
Form2 f2 = new Form2();
int flag = 0;
string u, p;
u = textBox1.Text;
p = textBox2.Text;
if(u=="username" && p=="pasword")
{
flag = 1;
}
else
{
MessageBox.Show("enter correct details");
}
if(flag==1)
{
f2.Show();
this.Hide();
}
}
In my case i had to hide submit button while users were selecting images.
This is what i come up:
$(document).on('click', '#image-field', function(e) {
$('.submit-button').prop('disabled', true)
})
$(document).on('focus', '#image-field'), function(e) {
$('.submit-button').prop('disabled', false)
})
#image-field
is my file selector. When somenone clicks on it, i disable the form submit button. The point is, when the file dialog closed - doesn't matter they select a file or cancel - #image-field
got the focus back, so i listen on that event.
UPDATE
I found that, this does not work in safari and poltergeist/phantomjs. Take this info into account if you would like to implement it.
You were right regarding how you want to generate salt i.e. its nothing but a random number. For this particular case it would protect your system from possible Dictionary attacks. Now, for the second problem what you could do is instead of using UTF-8 encoding you may want to use Base64. Here, is a sample for generating a hash. I am using Apache Common Codecs for doing the base64 encoding you may select one of your own
public byte[] generateSalt() {
SecureRandom random = new SecureRandom();
byte bytes[] = new byte[20];
random.nextBytes(bytes);
return bytes;
}
public String bytetoString(byte[] input) {
return org.apache.commons.codec.binary.Base64.encodeBase64String(input);
}
public byte[] getHashWithSalt(String input, HashingTechqniue technique, byte[] salt) throws NoSuchAlgorithmException {
MessageDigest digest = MessageDigest.getInstance(technique.value);
digest.reset();
digest.update(salt);
byte[] hashedBytes = digest.digest(stringToByte(input));
return hashedBytes;
}
public byte[] stringToByte(String input) {
if (Base64.isBase64(input)) {
return Base64.decodeBase64(input);
} else {
return Base64.encodeBase64(input.getBytes());
}
}
Here is some additional reference of the standard practice in password hashing directly from OWASP
The behaviour of datetime.datetime.utcnow()
returning UTC time as naive datetime object is obviously problematic and must be fixed. It can lead to unexpected result if your system local timezone is not UTC, since datetime library presume naive datetime object to represent system local time. For example, datetime.datetime.utcnow().timestaamp()
gives timestamp of 4 hours ahead from correct value on my computer. Also, as of python 3.6, datetime.astimezone()
can be called on naive datetime instances, but datetime.datetime.utcnow().astimezone(any_timezone)
gives wrong result unless your system local timezone is UTC.
Though it is an old question, it is still a valid one.
Expected behavior:

Explanation:
onchange
event handler is used to handle any change in file selection event.onchange
event is triggered only when the value of an element is changed. So, when we select the same file using the input
field the event will not be triggered. To overcome this, I set this.value = null;
at the end of the onchange
event function. It sets the file path of the selected file to null
. Thus, the onchange
event is triggered even at the time of the same file selection.To return only one row use LIMIT 1
:
SELECT *
FROM tbl_foo
WHERE name = 'sarmen'
LIMIT 1
It doesn't make sense to say 'first row' or 'last row' unless you have an ORDER BY
clause. Assuming you add an ORDER BY
clause then you can use LIMIT in the following ways:
LIMIT 1
.LIMIT 1, 1
.LIMIT 1
.Just want to share another option:
# mark two objects to be deleted
session.delete(obj1)
session.delete(obj2)
# commit (or flush)
session.commit()
http://docs.sqlalchemy.org/en/latest/orm/session_basics.html#deleting
In this example, the following codes shall works fine:
obj = User.query.filter_by(id=123).one()
session.delete(obj)
session.commit()
A smart pointer is an object that acts like a pointer, but additionally provides control on construction, destruction, copying, moving and dereferencing.
One can implement one's own smart pointer, but many libraries also provide smart pointer implementations each with different advantages and drawbacks.
For example, Boost provides the following smart pointer implementations:
shared_ptr<T>
is a pointer to T
using a reference count to determine when the object is no longer needed.scoped_ptr<T>
is a pointer automatically deleted when it goes out of scope. No assignment is possible.intrusive_ptr<T>
is another reference counting pointer. It provides better performance than shared_ptr
, but requires the type T
to provide its own reference counting mechanism.weak_ptr<T>
is a weak pointer, working in conjunction with shared_ptr
to avoid circular references.shared_array<T>
is like shared_ptr
, but for arrays of T
.scoped_array<T>
is like scoped_ptr
, but for arrays of T
.These are just one linear descriptions of each and can be used as per need, for further detail and examples one can look at the documentation of Boost.
Additionally, the C++ standard library provides three smart pointers; std::unique_ptr
for unique ownership, std::shared_ptr
for shared ownership and std::weak_ptr
. std::auto_ptr
existed in C++03 but is now deprecated.

Doing either
mystring == yourstring
or
mystring.eql? yourstring
Are equivalent.
In ExtJs, you can use
xtype: 'image'
to render a image.
Here is a fiddle showing rendering of binary data with extjs.
atob -- > converts ascii to binary
btoa -- > converts binary to ascii
Ext.application({
name: 'Fiddle',
launch: function () {
var srcBase64 = "data:image/jpeg;base64," + btoa(atob("iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8H8hYDwAFegHS8+X7mgAAAABJRU5ErkJggg=="));
Ext.create("Ext.panel.Panel", {
title: "Test",
renderTo: Ext.getBody(),
height: 400,
items: [{
xtype: 'image',
width: 100,
height: 100,
src: srcBase64
}]
})
}
});
Use prop
$(".checkBoxClass").prop('checked', true);
or to uncheck:
$(".checkBoxClass").prop('checked', false);
$("#ckbCheckAll").click(function () {
$(".checkBoxClass").prop('checked', $(this).prop('checked'));
});

VMware? No. However, QEMU has an x86_64 system target that you can use. You likely won't be able to use a VMware image directly (IIRC, there's no conversion tool), but you can install the OS and such yourself and work inside it. QEMU can be a bit of a PITA to get up and running, but it tends to work quite nicely.

You can change the format using the date() and the strtotime().
$date = '9/18/2019';
echo date('d-m-y',strtotime($date));
Result:
18-09-19
We can change the format by changing the ( d-m-y ).
Based on Daniel's answer, I think I've got something that works:
^(.(?!test))*$
The key is that you need to make the negative assertion on every character in the string
If you work in Eclipse, just make a cleanup (project\clean..
clean all projects
) of the project.
The solution of prijin worked perfectly for me. It is just fair to mention that two additional permissions are needed:
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
When these are added, enabling and disabling works flawless with the default bluetooth adapter.

Technically the answer of zlovelady is preferable, but as I had only to remove items from the navigation, the approach of unsetting the not-needed navigation items in the template was the fastest/easiest way for me:
Just duplicate
app/design/frontend/base/default/template/customer/account/navigation
to
app/design/frontend/YOUR_THEME/default/template/customer/account/navigation
and unset the unneeded navigation items before the get rendered, e.g.:
<?php $_links = $this->getLinks(); ?>
<?php
unset($_links['recurring_profiles']);
?>
I think you misunderstood the concept of session, session is a server side per-user-data-store which allows you to save user data on the server side.
thus, you have 2 options, resort to use cookies, which will give the illusion of session(but not quite the same), you can access cookies very simply by document.cookie .
but, if you want your server be aware of the session, you need to use some sort of server request probably the best way is to use AJAX to do this.
I would recommend you to re-read the definition of sessions.
I got this issue on a project with Dagger and multiple modules. What worked for me (none of the above worked) was to 1) empty the .gradle folder 2) empty the .idea folder 3) In project gradle.properties, mark org.gradle.caching=false 4) Possibly invalidate caches in AS, clean, rebuild
You may be able to get away with just #3, clean then build.
EDIT: Lately I've been able to get around this by restarting AS, then doing a clean, then install again.
Locking is platform and device specific, but generally, you have a few options:
For all these methods, you'll have to use a spin-lock (retry-after-failure) technique for acquiring and testing the lock. This does leave a small window for mis-synchronization, but its generally small enough to not be an major issue.
If you're looking for a solution that is cross platform, then you're better off logging to another system via some other mechanism (the next best thing is the NFS technique above).
Note that sqlite is subject to the same constraints over NFS that normal files are, so you can't write to an sqlite database on a network share and get synchronization for free.
I had the same error message in my localhost development with my Visual Studio. Note that everything was working when released with Microsoft Release Management (MRM). I fixed my situation by changing the initial value that was a MRM reference.
My App.config initial value was the following:
<connectionStrings>
<add name="BDORA" connectionString="__token3__" />
</connectionStrings>
Locally, the application execution could not interpret the token3 reference to its real value in Tokens.xml. To make it work on my localhost, I had to force the value from token3 in Tokens.xml into the App.config file.
As said before, switch can be used only with integer values. So, you just need to convert your "case" values to integer. You can achieve it by using constexpr from c++11, thus some calls of constexpr functions can be calculated in compile time.
something like that...
switch (str2int(s))
{
case str2int("Value1"):
break;
case str2int("Value2"):
break;
}
where str2int is like (implementation from here):
constexpr unsigned int str2int(const char* str, int h = 0)
{
return !str[h] ? 5381 : (str2int(str, h+1) * 33) ^ str[h];
}
Another example, the next function can be calculated in compile time:
constexpr int factorial(int n)
{
return n <= 1 ? 1 : (n * factorial(n-1));
}
int f5{factorial(5)};
// Compiler will run factorial(5)
// and f5 will be initialized by this value.
// so programm instead of wasting time for running function,
// just will put the precalculated constant to f5
I think you cannot speak of a "conversion" here. That will be a whole project. To "convert" it i think you have to write it again for the iphone.
Have a look at this question:
Is there a multiplatform framework for developing iPhone / Android applications?
As you can see from the answers there, there is no good way of developing applications for both platforms at the same time (except if you're developing games where flash makes it easy to be portable).
.search-table-outter {border:2px solid red; overflow-x:scroll;}
.search-table{table-layout: fixed; margin:40px auto 0px auto; }
.search-table, td, th{border-collapse:collapse; border:1px solid #777;}
th{padding:20px 7px; font-size:15px; color:#444; background:#66C2E0;}
td{padding:5px 10px; height:35px;}
You should provide scroll in div.
The best way is to use IN
statement :
DELETE from tablename WHERE id IN (1,2,3,...,254);
You can also use BETWEEN
if you have consecutive IDs :
DELETE from tablename WHERE id BETWEEN 1 AND 254;
You can of course limit for some IDs using other WHERE clause :
DELETE from tablename WHERE id BETWEEN 1 AND 254 AND id<>10;
Assuming you mean "file on a local filesystem" when you say .json file.
You'll need to save the json data formatted as jsonp, and use a file:// url
to access it.
Your HTML will look like this:
<script src="file://c:\\data\\activity.jsonp"></script>
<script type="text/javascript">
function updateMe(){
var x = 0;
var activity=jsonstr;
foreach (i in activity) {
date = document.getElementById(i.date).innerHTML = activity.date;
event = document.getElementById(i.event).innerHTML = activity.event;
}
}
</script>
And the file c:\data\activity.jsonp contains the following line:
jsonstr = [ {"date":"July 4th", "event":"Independence Day"} ];
use: preserve-order="true" enabled="true" that would run test cases in the manner in which you have written.
<suite name="Sanity" verbose="1" parallel="" thread-count="">
<test name="Automation" preserve-order="true" enabled="true">
<listeners>
<listener class-name="com.yourtest.testNgListner.RetryListener" />
</listeners>
<parameter name="BrowserName" value="chrome" />
<classes>
<class name="com.yourtest.Suites.InitilizeClass" />
<class name="com.yourtest.Suites.SurveyTestCases" />
<methods>
<include name="valid_Login" />
<include name="verifyManageSurveyPage" />
<include name="verifySurveyDesignerPage" />
<include name="cloneAndDeleteSurvey" />
<include name="createAndDelete_Responses" />
<include name="previewSurvey" />
<include name="verifySurveyLink" />
<include name="verifySurveyResponses" />
<include name="verifySurveyReports" />
</methods>

This is covered in the PHP documentation for booleans and type comparison tables.
When converting to boolean, the following values are considered FALSE:
FALSE
itself0
(zero)0.0
(zero)'0'
NULL
(including unset variables)Every other value is considered TRUE.
Setting the id attribute when appending the svg element can also let d3 select so remove() later on this element by id :
var svg = d3.select("theParentElement").append("svg")
.attr("id","the_SVG_ID")
.attr("width",...
...
d3.select("#the_SVG_ID").remove();
I had the exact same problem. Running mvn clean install
instead of mvn clean compile
resolved it.
The difference only occurs when using multi-maven-project since the project dependencies are uploaded to the local repository by using install.
If all you want is a JS implementation of a base64-encoder, so that you can send data back, you can try the btoa
function.
b64enc = btoa(uint);
A couple of quick notes on btoa - it's non-standard, so browsers aren't forced to support it.
However, most browsers do. The big ones, at least. atob
is the opposite conversion.
If you need a different implementation, or you find an edge-case where the browser has no idea what you're talking about, searching for a base64 encoder for JS wouldn't be too hard.
I think there are 3 of them hanging around on my company's website, for some reason...
In these days of Git everywhere, you may forget CMake and use git clean -d -f -x
, that will remove all files not under source control.
You can try simpleBootstrapDialog. Here you can pass title, message, callback options for cancel and submit etc...
To use this plugin include simpleBootstrapDialog.js file like below
<script type="text/javascript" src="/simpleDialog.js"></script>
Basic Usage
<script type="text/javascript>
$.simpleDialog();
</script>
Custom Title and description
$.simpleDialog({
title:"Alert Dialog",
message:"Alert Message"
});
With Callback
<script type="text/javascript>
$.simpleDialog({
onSuccess:function(){
alert("You confirmed");
},
onCancel:function(){
alert("You cancelled");
}
});
</script>
1st of all, when you declare a variable in java, you should declare it using Interfaces even if you specify the implementation when instantiating it
ArrayList<ArrayList<String>> listOfLists = new ArrayList<ArrayList<String>>();
should be written
List<List<String>> listOfLists = new ArrayList<List<String>>(size);
Then you will have to instantiate all columns of your 2d array
for(int i = 0; i < size; i++) {
listOfLists.add(new ArrayList<String>());
}
And you will use it like this :
listOfLists.get(0).add("foobar");
But if you really want to "create a 2D array that each cell is an ArrayList!"
Then you must go the dijkstra way.
This recently worked for me. You just need to add to your packages, so that the package manager would be aware of the packages:
Add the Sublime Text 2 Repository to your Synaptic Package Manager:
sudo add-apt-repository ppa:webupd8team/sublime-text-2
Update
sudo apt-get update
Install Sublime Text:
sudo apt-get install sublime-text
The main use of -f
is to force the removal of files that would
not be removed using rm
by itself (as a special case, it "removes"
non-existent files, thus suppressing the error message).
You can also just redirect the error message using
$ rm file.txt 2> /dev/null
(or your operating system's equivalent). You can check the value of $?
immediately after calling rm
to see if a file was actually removed or not.
The function you are looking for is get()
:
assign ("abc",5)
get("abc")
Confirming that the memory address is identical:
getabc <- get("abc")
pryr::address(abc) == pryr::address(getabc)
# [1] TRUE
Reference: R FAQ 7.21 How can I turn a string into a variable?
On some investigation, the answer appears to be (a).
When I go to change the settings, the settings file goes into a .vscode directory in my project directory.
I did it with an ajax post and then returned using a data url:
$(document).ready(function () {
var exportClick = function () {
$.ajax({
url: "/api/test.php",
type: "POST",
dataType: "text",
data: {
action: "getCSV",
filter: "name = 'smith'",
},
success: function(data) {
var w = window.open('data:text/csv;charset=utf-8,' + encodeURIComponent(data));
w.focus();
},
error: function () {
alert('Problem getting data');
},
});
}
});
you can do something like adding a class to add border radius
HTML:
<a href="#" class="btn btn-default btn-circle"><i class="fa fa-user"></i></a>
CSS:
.btn-circle {
width: 30px;
height: 30px;
text-align: center;
padding: 6px 0;
font-size: 12px;
line-height: 1.42;
border-radius: 15px;
}
in case you wanted to change dimension you need to change the font size or padding accordingly
The warning message
[WARNING] The requested profile "pom.xml" could not be activated because it does not exist.
means that you somehow passed -P pom.xml
to Maven which means "there is a profile called pom.xml
; find it and activate it". Check your environment and your settings.xml
for this flag and also look at all <profile>
elements inside the various XML files.
Usually, mvn help:effective-pom
is also useful to see what the real POM would look like.
Now the error means that you tried to configure Maven to build Java 8 code but you're not using a Java 8 runtime. Solutions:
JAVA_HOME
is your friendpom.xml
to a Java version which you actually have.Related:
On Android, use the static methods of the android.util.Base64 utility class. The referenced documentation says that the Base64 class was added in API level 8 (Android 2.2 (Froyo)).
import android.util.Base64;
byte[] encodedBytes = Base64.encode("Test".getBytes());
Log.d("tag", "encodedBytes " + new String(encodedBytes));
byte[] decodedBytes = Base64.decode(encodedBytes);
Log.d("tag", "decodedBytes " + new String(decodedBytes));
You can do something like this
var now = moment();
var time = now.hour() + ':' + now.minutes() + ':' + now.seconds();
time = time + ((now.hour()) >= 12 ? ' PM' : ' AM');
I stop at three parameters as a general rule of thumb. Any more and it's time to pass an array of parameters or a configuration object instead, which also allows for future parameters to be added without changing the API.
It's a reserved keyword (like return, filter, function, break).
Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:
But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.
Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:
PS C:\> function ex{exit}
PS C:\> new-alias ^D ex
First you must visit MDN IIFE , Now some points about this
This returns a string, so that results without fractional parts, and small values which would otherwise appear in E notation are shown correctly:
def sigfig(x, num_sigfig):
num_decplace = num_sigfig - int(math.floor(math.log10(abs(x)))) - 1
return '%.*f' % (num_decplace, round(x, num_decplace))
Length of characters to be matched.
{n,m} n <= length <= m
{n} length == n
{n,} length >= n
And by default, the engine is greedy to match this pattern. For example, if the input is 123456789, \d{2,5} will match 12345 which is with length 5.
If you want the engine returns when length of 2 matched, use \d{2,5}?
Yes:
Use this to experiment with mailto form elements and link encoding.
You can enter subject, body (i.e. content), etc. into the form, hit the button and see the mailto html link that you can paste into your page.
You can even specify elements that are rarely known and used: cc, bcc, from emails.
If you're looking for a specific type of control you could use a recursive loop like this one - http://weblogs.asp.net/eporter/archive/2007/02/24/asp-net-findcontrol-recursive-with-generics.aspx
Here's an example I made that returns all controls of the given type
/// <summary>
/// Finds all controls of type T stores them in FoundControls
/// </summary>
/// <typeparam name="T"></typeparam>
private class ControlFinder<T> where T : Control
{
private readonly List<T> _foundControls = new List<T>();
public IEnumerable<T> FoundControls
{
get { return _foundControls; }
}
public void FindChildControlsRecursive(Control control)
{
foreach (Control childControl in control.Controls)
{
if (childControl.GetType() == typeof(T))
{
_foundControls.Add((T)childControl);
}
else
{
FindChildControlsRecursive(childControl);
}
}
}
}
string = string.substring(0, (string.length() - 1));
I'm using this in my code, it's easy and simple. it only works while the String is > 0. I have it connected to a button and inside the following if statement
if (string.length() > 0) {
string = string.substring(0, (string.length() - 1));
}
The action
attribute will default to the current URL. It is the most reliable and easiest way to say "submit the form to the same place it came from".
There is no reason to use $_SERVER['PHP_SELF']
, and #
doesn't submit the form at all (unless there is a submit
event handler attached that handles the submission).
Whatever approach you take, make sure in the end that you have an updated version of curl and libcurl. You can do curl --version
and see the versions.
Here's what I did to get the latest curl version installed in Ubuntu:
sudo add-apt-repository "deb http://mirrors.kernel.org/ubuntu wily main"
sudo apt-get update
sudo apt-get install curl
import codecs
f=codecs.open("test.html", 'r')
print f.read()
Try something like this.
Although Bootstrap CDN restored glyphicons to bootstrap.min.css, Bootstrap CDN's Bootswatch css files doesn't include glyphicons.
For example Amelia theme: http://bootswatch.com/amelia/
Default Amelia has glyphicons in this file: http://bootswatch.com/amelia/bootstrap.min.css
But Bootstrap CDN's css file doesn't include glyphicons: http://netdna.bootstrapcdn.com/bootswatch/3.0.0/amelia/bootstrap.min.css
So as @edsioufi mentioned, you should include you should include glphicons css, if you use Bootswatch files from the bootstrap CDN. File: http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css
Symfony 3.0
Prior to Symfony 2.6
you would use SecurityContext
.
SecurityContext
will be deprecated in Symfony 3.0
in favour of the AuthorizationChecker
.
For Symfony 2.6+
& Symfony 3.0
use AuthorizationChecker
.
// Get our Security Context Object - [deprecated in 3.0]
$security_context = $this->get('security.context');
# e.g: $security_context->isGranted('ROLE_ADMIN');
// Get our Token (representing the currently logged in user)
$security_token = $security_context->getToken();
# e.g: $security_token->getUser();
# e.g: $security_token->isAuthenticated();
# [Careful] ^ "Anonymous users are technically authenticated"
// Get our user from that security_token
$user = $security_token->getUser();
# e.g: $user->getEmail(); $user->isSuperAdmin(); $user->hasRole();
// Check for Roles on the $security_context
$isRoleAdmin = $security_context->isGranted('ROLE_ADMIN');
# e.g: (bool) true/false
security.context
becomes security.authorization_checker
.
We now get our token from security.token_storage
instead of the security.context
// [New 3.0] Get our "authorization_checker" Object
$auth_checker = $this->get('security.authorization_checker');
# e.g: $auth_checker->isGranted('ROLE_ADMIN');
// Get our Token (representing the currently logged in user)
// [New 3.0] Get the `token_storage` object (instead of calling upon `security.context`)
$token = $this->get('security.token_storage')->getToken();
# e.g: $token->getUser();
# e.g: $token->isAuthenticated();
# [Careful] ^ "Anonymous users are technically authenticated"
// Get our user from that token
$user = $token->getUser();
# e.g (w/ FOSUserBundle): $user->getEmail(); $user->isSuperAdmin(); $user->hasRole();
// [New 3.0] Check for Roles on the $auth_checker
$isRoleAdmin = $auth_checker->isGranted('ROLE_ADMIN');
// e.g: (bool) true/false

The cleanest way is use a function of janitor
package that is built for exactly this purpose.
janitor::row_to_names(DF,1)
If you want to use any other row than the first one, pass it in the second parameter.
From the Sublime Text docs for Windows/Linux:
Keypress Command
Ctrl + K, Ctrl + U Transform to Uppercase
Ctrl + K, Ctrl + L Transform to Lowercase
and for Mac:
Keypress Command
cmd + KU Transform to Uppercase
cmd + KL Transform to Lowercase
Also note that Ctrl + Shift + p in Windows (? + Shift + p in a Mac) brings up the Command Palette where you can search for these and other commands. It looks like this:
It can be fixed by placing the lines in the android manifest file:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
Sometimes it doesn't get login with username = root
and password
, then you can change the default settings or the reset settings.
Open config.inc.php
file in the phpmyadmin folder
Instead of
$cfg['Servers'][$i]['AllowNoPassword'] = false;
change it to:
$cfg['Servers'][$i]['AllowNoPassword'] = true;
Do not specify any password and put the user name as it was before, which means root
.
E.g.
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '';
This worked for me after i had edited my config.inc.php
file.
If you want to use asynchronous method you need to use callback function by $promise, here is example:
var Regions = $resource('mocks/regions.json');
$scope.regions = Regions.query();
$scope.regions.$promise.then(function (result) {
$scope.regions = result;
});
I'm trying this before
cd /opt/lampp/phpmyadmin
Then
gedit config.inc.php
Find this
$cfg['Servers'][$i]['host'] =
If there is localhost
change it to 127.0.0.1
Note : if there is '//' remove // before
$cfg['Servers'][$i]['host']
I checked again http://localhost/phpmyadmin/
Mysqli said:
"phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server."
I'm opening again config.inc.php
and I found
$cfg['Servers'][$i]['password'] =
Fill the password with your password
It worked for me. It may work for you too.
The DLL you're looking for that contains that namespace is
Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll
Note that unit testing cannot be used in Visual Studio Express.
Can also invoke oShell.Exec in order to be able to read STDIN/STDOUT/STDERR responses. Perfect for error checking which it seems you're doing with your sanity .BAT.
It must be an array if you want to iterate over it. You're very likely missing [

"fromWho": "[email protected]"
}, {
"id": "2",

"fromWho": "[email protected]"
}];
var $output = $('#output');
for(var i = 0; i < x.length; i++) {
console.log(x[i].id);
}

There are no gotchas. The default construction of std::string
is ""
. But you cannot compare a string to NULL
. The closest you can get is to check whether the string is empty or not, using the std::string::empty
method..
public static bool isInteger(decimal n)
{
return n - (Int64)n == 0;
}
A simple solution is to use BindingList<T>
instead of ObservableCollection<T>
. Indeed the BindingList relay item change notifications. So with a binding list, if the item implements the interface INotifyPropertyChanged
then you can simply get notifications using the ListChanged event.

Try with Shadow( Like border ) + Border

box-shadow: 0 5px 0 #ffbf0e;
You can also make two random integers and verify if they are the same, this gives you more control over the probabilities.
Random rand = new Random();
Declare a range to manage random probability. In this example, there is a 50% chance of being true.
int range = 2;
Generate 2 random integers.
int a = rand.nextInt(range);
int b = rand.nextInt(range);
Then simply compare return the value.
return a == b;
I also have a class you can use. RandomRange.java
They all do different things, since matplotlib uses a hierarchical order in which a figure window contains a figure which may consist of many axes. Additionally, there are functions from the pyplot interface and there are methods on the Figure
class. I will discuss both cases below.
pyplot
is a module that collects a couple of functions that allow matplotlib to be used in a functional manner. I here assume that pyplot
has been imported as import matplotlib.pyplot as plt
.
In this case, there are three different commands that remove stuff:
plt.cla()
clears an axes, i.e. the currently active axes in the current figure. It leaves the other axes untouched.
plt.clf()
clears the entire current figure with all its axes, but leaves the window opened, such that it may be reused for other plots.
plt.close()
closes a window, which will be the current window, if not specified otherwise.
Which functions suits you best depends thus on your use-case.
The close()
function furthermore allows one to specify which window should be closed. The argument can either be a number or name given to a window when it was created using figure(number_or_name)
or it can be a figure instance fig
obtained, i.e., usingfig = figure()
. If no argument is given to close()
, the currently active window will be closed. Furthermore, there is the syntax close('all')
, which closes all figures.
Additionally, the Figure
class provides methods for clearing figures.
I'll assume in the following that fig
is an instance of a Figure
:
fig.clf()
clears the entire figure. This call is equivalent to plt.clf()
only if fig
is the current figure.
fig.clear()
is a synonym for fig.clf()
Note that even del fig
will not close the associated figure window. As far as I know the only way to close a figure window is using plt.close(fig)
as described above.

For me, when I was running "flutter doctor" command from Ubuntu Command line - It showed me below error.
[?] Android toolchain - develop for Android devices ? Unable to locate Android SDK.
From this error, it is obvious that "flutter doctor" was not able to find the "android sdk" and the reason for that was my android sdk was downloaded in a custom location on my Ubuntu machine.
So we must need to tell "flutter doctor" about this custom android location, using below command,
flutter config --android-sdk /home/myhome/Downloads/softwares/android-sdk/
Need to replace /home/myhome/Downloads/softwares/android-sdk/
with path to your custom location/place where android sdk is available.
Once this is done, and re-run "flutter doctor" and now it has detected the android sdk location and hence I could run avd/emulator by typing "flutter run"
There is a special trick I discovered by accident.
The more general answer is
UPDATE mysql.user SET host = {newhost} WHERE user = {youruser}
.pyc
contain the compiled bytecode of Python source files. The Python interpreter loads .pyc
files before .py
files, so if they're present, it can save some time by not having to re-compile the Python source code. You can get rid of them if you want, but they don't cause problems, they're not big, and they may save some time when running programs.

Because to declare a type, its size needs to be known. You can forward declare a pointer to the type, or typedef a pointer to the type.
If you really want to, you can use the pimpl idiom to keep the includes down. But if you want to use a type, rather than a pointer, the compiler has to know its size.
Edit: j_random_hacker adds an important qualification to this answer, basically that the size needs to be know to use the type, but a forward declaration can be made if we only need to know the type exists, in order to create pointers or references to the type. Since the OP didn't show code, but complained it wouldn't compile, I assumed (probably correctly) that the OP was trying to use the type, not just refer to it.

Create a relative div that is placed in the flow of the page; place the base image first as relative so that the div knows how big it should be; place the overlays as absolutes relative to the upper left of the first image. The trick is to get the relatives and absolutes correct.
You can iterate using the index access,
To avoid O(n^2) complexity you can use two indices, i - current testing index, j - index to store next item and at the end of the cycle new size of the vector.
code:
void erase(std::vector<int>& v, int num)
{
size_t j = 0;
for (size_t i = 0; i < v.size(); ++i) {
if (v[i] != num) v[j++] = v[i];
}
// trim vector to new size
v.resize(j);
}
In such case you have no invalidating of iterators, complexity is O(n), and code is very concise and you don't need to write some helper classes, although in some case using helper classes can benefit in more flexible code.
This code does not use erase
method, but solves your task.
Using pure stl you can do this in the following way (this is similar to the Motti's answer):
#include <algorithm>
void erase(std::vector<int>& v, int num) {
vector<int>::iterator it = remove(v.begin(), v.end(), num);
v.erase(it, v.end());
}
I had created a symlink, but it still wasn't working.

for linux (bash) following code works for me:

the \033[31m will switch the color to red and \033[0m will switch it back to normal.
$str = preg_replace('/\?\//', '?', $str);
Edit: See CMS' answer. It's late, I should know better.
Since the data is not free, you can use this Bloomberg API Emulator (disclaimer: it's my project) to learn how to send requests and make subscriptions. This emulator looks and acts just like the real Bloomberg API, although it doesn't return real data. In my time developing applications that use the Bloomberg API, I rarely care about the actual data that I'm handling; I care about how to retrieve data.
If you want to learn how to use the Bloomberg API give it a try. If you want to test out your code without an account, use this. A Bloomberg account costs about $2,000 a month, so you can save a lot with this project.
The emulator now supports Java and C++ in addition to C#.
C#, C++, and Java:
I have written a script that does this myself:
#!/bin/bash
LANG=C
if [ -z "$1" ]; then
if [ "$(tty)" = "not a tty" ]; then
p=`cat`;
else
echo "No timestamp given."
exit
fi
else
p=$1
fi
echo $p | gawk '{ print strftime("%c", $0); }'
Edit:
Android 5.0 (API level 21) and higher uses ART which supports multidexing. Therefore, if your minSdkVersion
is 21 or higher, the multidex support library is not needed.
Modify your build.gradle
:
android {
compileSdkVersion 22
buildToolsVersion "23.0.0"
defaultConfig {
minSdkVersion 14 //lower than 14 doesn't support multidex
targetSdkVersion 22
// Enabling multidex support.
multiDexEnabled true
}
}
dependencies {
implementation 'com.android.support:multidex:1.0.3'
}
If you are running unit tests, you will want to include this in your Application
class:
public class YouApplication extends Application {
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
Or just make your application
class extend MultiDexApplication
public class Application extends MultiDexApplication {
}
For more info, this is a good guide.
I had the same problem, and tried a lot of different variants. After some tries I became able to sudo gem install
, but still have problem to install it without sudo.
Finally I found a decission - reinstalling of rvm helped me. Probably it can save time somebody else.
You need to add a '/' after the dir name
<exclude name="WEB-INF/" />
The problem I see here is that "sum" is an aggregate function.
first, you need to fix the query itself.
Select sum(c_counts + f_counts) total, [column to group sums by]
from table
group by [column to group sums by]
then, you can sort it:
Select *
from (query above) a
order by total
EDIT: But see post by Virat. Perhaps what you want is not the sum of your total fields over a group, but just the sum of those fields for each record. In that case, Virat has the right solution.
As user2357112 mentioned in the comments, you cannot use chained comparisons here. For elementwise comparison you need to use &
. That also requires using parentheses so that &
wouldn't take precedence.
It would go something like this:
mask = ((50 < df['heart rate']) & (101 > df['heart rate']) & (140 < df['systolic...
In order to avoid that, you can build series for lower and upper limits:
low_limit = pd.Series([90, 50, 95, 11, 140, 35], index=df.columns)
high_limit = pd.Series([160, 101, 100, 19, 160, 39], index=df.columns)
Now you can slice it as follows:
mask = ((df < high_limit) & (df > low_limit)).all(axis=1)
df[mask]
Out:
dyastolic blood pressure heart rate pulse oximetry respiratory rate \
17 136 62 97 15
69 110 85 96 18
72 105 85 97 16
161 126 57 99 16
286 127 84 99 12
435 92 67 96 13
499 110 66 97 15
systolic blood pressure temperature
17 141 37
69 155 38
72 154 36
161 153 36
286 156 37
435 155 36
499 149 36
And for assignment you can use np.where:
df['class'] = np.where(mask, 'excellent', 'critical')
It's also possible to set both the From name and from address using something like:
echo test | mail -s "test" [email protected] -- -F'Some Name<[email protected]>' -t
For some reason passing -F'Some Name'
and [email protected]
doesn't work, but passing in the -t
to sendmail works and is "easy".
The article The essential difference between Constructor and ngOnInit in Angular explores the difference from multiple perspectives. This answer provides the most important difference explanation related to the component initialization process which also shows the different in usage.
Angular bootstrap process consists of the two major stages:
The constructor of the component is called when Angular constructs components tree. All lifecycle hooks are called as part of running change detection.
When Angular constructs components tree the root module injector is already configured so you can inject any global dependencies. Also, when Angular instantiates a child component class the injector for the parent component is also already set up so you can inject providers defined on the parent component including the parent component itself. Component constructors is the only method that is called in the context of the injector so if you need any dependency that's the only place to get those dependencies.
When Angular starts change detection the components tree is constructed and the constructors for all components in the tree have been called. Also every component's template nodes are added to the DOM. The @Input
communication mechanism is processed during change detection so you cannot expect to have the properties available in the constructor. It will be available on after ngOnInit
.
Let's see a quick example. Suppose you have the following template:
<my-app>
<child-comp [i]='prop'>
So Angular starts bootstrapping the application. As I said it first creates classes for each component. So it calls MyAppComponent
constructor. It also creates a DOM node which is the host element of the my-app
component. Then it proceeds to creating a host element for the child-comp
and calling ChildComponent
constructor. At this stage it's not really concerned with the i
input binding and any lifecycle hooks. So when this process is finished Angular ends up with the following tree of component views:
MyAppView
- MyApp component instance
- my-app host element data
ChildCompnentView
- ChildComponent component instance
- child-comp host element data
Only then runs change detection and updates bindings for the my-app
and calls ngOnInit
on the MyAppComponent class. Then it proceeds to updating the bindings for the child-comp
and calls ngOnInit
on the ChildComponent class.
You can do your initialization logic in either constructor or ngOnInit
depending on what you need available. For example the article Here is how to get ViewContainerRef before @ViewChild query is evaluated shows what type of initialization logic can be required to be performed in the constructor.
Here are some articles that will help you understand the topic better:
I am not familiar with JXL and but we use POI. POI is well maintained and can handle both the binary .xls format and the new xml based format that was introduced in Office 2007.
CSV files are not excel files, they are text based files, so these libraries don't read them. You will need to parse out a CSV file yourself. I am not aware of any CSV file libraries, but I haven't looked either.
Format won't be completely the same, but it does write the data to a text file, and R will be able to reread it using dget
when you want to retrieve it again as a list.
dput(mylist, "mylist.txt")
As of ES 7, mapping types have been removed. You can read more details here
If you are using Ruby On Rails this means that you may need to remove document_type
from your model or concern.
As an alternative to mapping types one solution is to use an index per document type.
Before:
module Searchable
extend ActiveSupport::Concern
included do
include Elasticsearch::Model
include Elasticsearch::Model::Callbacks
index_name [Rails.env, Rails.application.class.module_parent_name.underscore].join('_')
document_type self.name.downcase
end
end
After:
module Searchable
extend ActiveSupport::Concern
included do
include Elasticsearch::Model
include Elasticsearch::Model::Callbacks
index_name [Rails.env, Rails.application.class.module_parent_name.underscore, self.name.downcase].join('_')
end
end
One example:
List somelist = new ArrayList();
You can look at the javadoc for List and find all known implementing classes of the List
interface that are included with the java api.
The RootTools library offers simple methods to check for root:
RootTools.isRootAvailable()
It enables error handling. The following is partly from https://msdn.microsoft.com/en-us/library/5hsw66as.aspx
' Enable error handling. When a run-time error occurs, control goes to the statement
' immediately following the statement where the error occurred, and execution
' continues from that point.
On Error Resume Next
SomeCodeHere
If Err.Number = 0 Then
WScript.Echo "No Error in SomeCodeHere."
Else
WScript.Echo "Error in SomeCodeHere: " & Err.Number & ", " & Err.Source & ", " & Err.Description
' Clear the error or you'll see it again when you test Err.Number
Err.Clear
End If
SomeMoreCodeHere
If Err.Number <> 0 Then
WScript.Echo "Error in SomeMoreCodeHere:" & Err.Number & ", " & Err.Source & ", " & Err.Description
' Clear the error or you'll see it again when you test Err.Number
Err.Clear
End If
' Disables enabled error handler in the current procedure and resets it to Nothing.
On Error Goto 0
' There are also `On Error Goto -1`, which disables the enabled exception in the current
' procedure and resets it to Nothing, and `On Error Goto line`,
' which enables the error-handling routine that starts at the line specified in the
' required line argument. The line argument is any line label or line number. If a run-time
' error occurs, control branches to the specified line, making the error handler active.
' The specified line must be in the same procedure as the On Error statement,
' or a compile-time error will occur.
Rather than using Ctrl + K, X you can also just type prop
and then hit Tab twice.
remove the android:targetSdkVersion="21"
from manifest.xml. it will work!
and from this there is no prob at all in your apk it just a trick i apply this and i found colorful icon in notification
error 'Class' does not name a type
Just in case someone does the same idiotic thing I did ... I was creating a small test program from scratch and I typed Class instead of class (with a small C). I didn't take any notice of the quotes in the error message and spent a little too long not understanding my problem.
My search for a solution brought me here so I guess the same could happen to someone else.
Here's a general solution, that
Test with numerical comparison
a=$(if [ "$b" -eq 5 ]; then echo "$c"; else echo "$d"; fi)
Test with String comparison
a=$(if [ "$b" = "5" ]; then echo "$c"; else echo "$d"; fi)
In ES2015, you can use class
to do this cleanly:
class NotImplemented extends Error {
constructor(message = "", ...args) {
super(message, ...args);
this.message = message + " has not yet been implemented.";
}
}
This does not modify the global Error
prototype, allows you to customize message
, name
, and other attributes, and properly captures the stack. It's also pretty readable.
Of course, you may need to use a tool like babel
if your code will be running on older browsers.
as explained here
With help from numpy one can calculate for example a linear fitting.
# plot the data itself
pylab.plot(x,y,'o')
# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])
An activity populates the ActionBar in its onCreateOptionsMenu()
method.
Instead of using setcustomview()
, just override onCreateOptionsMenu
like this:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mainmenu, menu);
return true;
}
If an actions in the ActionBar is selected, the onOptionsItemSelected()
method is called. It receives the selected action as parameter. Based on this information you code can decide what to do for example:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menuitem1:
Toast.makeText(this, "Menu Item 1 selected", Toast.LENGTH_SHORT).show();
break;
case R.id.menuitem2:
Toast.makeText(this, "Menu item 2 selected", Toast.LENGTH_SHORT).show();
break;
}

You're all concentrating on the word 'get' in the question. Try the 'elements' property of any form which is a collection that you can iterate through i.e. you write your own 'get' function.
Example:
function getFormElelemets(formName){
var elements = document.forms[formName].elements;
for (i=0; i<elements.length; i++){
some code...
}
}
Hope that helps.
In our particular case, we use Stash as our remote Git repository. We tried all the previous answers and nothing was working. We ended up having to do the following:
git branch –D branch-name (delete from local)
git push origin :branch-name (delete from remote)
Then when users went to pull changes, they needed to do the following:
git fetch -p
It sounds like you want to use a transparent background, in which case you could try using the rgba()
function:
rgba(R, G, B, A)
R (red), G (green), and B (blue) can be either
<integer>
s or<percentage>
s, where the number 255 corresponds to 100%. A (alpha) can be a<number>
between 0 and 1, or a<percentage>
, where the number 1 corresponds to 100% (full opacity).RGBa example
rgba(51, 170, 51, .1) /* 10% opaque green */ rgba(51, 170, 51, .4) /* 40% opaque green */ rgba(51, 170, 51, .7) /* 70% opaque green */ rgba(51, 170, 51, 1) /* full opaque green */
A small example showing how rgba
can be used.
As of 2018, practically every browser supports the rgba
syntax.
To post a nested object with the key-value interface you can use a similar method to sending arrays. Pass an object key in square brackets after the object index.
"Items": [
{
"sku": "9257",
"Price": "100"
}
]
def map = [:]
map["stringKey"] = [1, 2, 3, 4]
map["anotherKey"] = [55, 66, 77]
assert map["anotherKey"] == [55, 66, 77]
I know this has been answered but I have a slightly more elegant way to copy from asset directory to a file on the sdcard. It requires no "for" loop but instead uses File Streams and Channels to do the work.
(Note) If using any type of compressed file, APK, PDF, ... you may want to rename the file extension before inserting into asset and then rename once you copy it to SDcard)
AssetManager am = context.getAssets();
AssetFileDescriptor afd = null;
try {
afd = am.openFd( "MyFile.dat");
// Create new file to copy into.
File file = new File(Environment.getExternalStorageDirectory() + java.io.File.separator + "NewFile.dat");
file.createNewFile();
copyFdToFile(afd.getFileDescriptor(), file);
} catch (IOException e) {
e.printStackTrace();
}
A way to copy a file without having to loop through it.
public static void copyFdToFile(FileDescriptor src, File dst) throws IOException {
FileChannel inChannel = new FileInputStream(src).getChannel();
FileChannel outChannel = new FileOutputStream(dst).getChannel();
try {
inChannel.transferTo(0, inChannel.size(), outChannel);
} finally {
if (inChannel != null)
inChannel.close();
if (outChannel != null)
outChannel.close();
}
}
For me the answer of @Dane White is OK, first I did not like using Runnable
but I could not find any alternatives.
Here another implementation I preferred more:
public class OptionalConsumer<T> {
private Optional<T> optional;
private OptionalConsumer(Optional<T> optional) {
this.optional = optional;
}
public static <T> OptionalConsumer<T> of(Optional<T> optional) {
return new OptionalConsumer<>(optional);
}
public OptionalConsumer<T> ifPresent(Consumer<T> c) {
optional.ifPresent(c);
return this;
}
public OptionalConsumer<T> ifNotPresent(Runnable r) {
if (!optional.isPresent()) {
r.run();
}
return this;
}
}
Then:
Optional<Any> o = Optional.of(...);
OptionalConsumer.of(o).ifPresent(s -> System.out.println("isPresent " + s))
.ifNotPresent(() -> System.out.println("! isPresent"));
Update 1:
the above solution for the traditional way of development when you have the value and want to process it but what if I want to define the functionality and the execution will be then, check below enhancement;
public class OptionalConsumer<T> implements Consumer<Optional<T>> {
private final Consumer<T> c;
private final Runnable r;
public OptionalConsumer(Consumer<T> c, Runnable r) {
super();
this.c = c;
this.r = r;
}
public static <T> OptionalConsumer<T> of(Consumer<T> c, Runnable r) {
return new OptionalConsumer(c, r);
}
@Override
public void accept(Optional<T> t) {
if (t.isPresent()) {
c.accept(t.get());
}
else {
r.run();
}
}
Then could be used as:
Consumer<Optional<Integer>> c = OptionalConsumer.of(
System.out::println,
() -> System.out.println("Not fit")
);
IntStream.range(0, 100)
.boxed()
.map(i -> Optional.of(i)
.filter(j -> j % 2 == 0))
.forEach(c);
In this new code you have 3 things:
By the way, now its name is more descriptive it is actually Consumer<Optional<?>>

I tried the answers here in a giant for...if loop, but didn't get any joy - so I did it like this, maybe messy but did the job:
# EXP_LIST2 is iterated
# imagine a for loop
EXP_LIST="List item"
EXP_LIST2="$EXP_LIST2 \n $EXP_LIST"
done
echo -e $EXP_LIST2
although that added a space to the list, which is fine - I wanted it indented a bit. Also presume the "\n" could be printed in the original $EP_LIST.
csvde -f test.csv
This command will perform a CSV dump of every entry in your Active Directory server. You should be able to see the full DN's of users and groups.
You will have to go through that output file and get rid off the unnecessary content.
My solution is a bit different:
$( 'input[name="your_radio_input_name"]:radio:first' ).click();
In IOS 8 do it like
navigationController?.hidesBarsOnTap = true
but only when it's part of a UINavigationController
make it false when you want it back
I was able to fix this issue by changing the mail settings in the system.net portion of my web.config:
<mailSettings>
<smtp deliveryMethod="Network">

</smtp>
</mailSettings>
Actually in case if you have any file that has key value pairs like this:
someKey=someValue
someOtherKey=someOtherValue
You can import that into webpack by a npm module called properties-reader
I found this really helpful since I'm integrating react with Java Spring framework where there is already an application.properties file. This helps me to keep all config together in one place.
"properties-reader": "0.0.16"
const PropertiesReader = require('properties-reader');
const appProperties = PropertiesReader('Path/to/your/properties.file')._properties;
externals: {
'Config': JSON.stringify(appProperties)
}
var Config = require('Config')
fetchData(Config.serverUrl + '/Enterprises/...')
I think this is the simplest answer possible: 2 lines and very comprehensible. It emulates the functionality of dragging a formula written in a cell across a range of cells.
Range("C1").Formula = "=A1+B1"
Range("C1:C10").FillDown
browser's back/forward button solution
I encountered the same problem and I solved it using the popstate event
from the $window object and ui-router's $state object
. A popstate event is dispatched to the window every time the active history entry changes.
The $stateChangeSuccess
and $locationChangeSuccess
events are not triggered on browser's button click even though the address bar indicates the new location.
So, assuming you've navigated from states main
to folder
to main
again, when you hit back
on the browser, you should be back to the folder
route. The path is updated but the view is not and still displays whatever you have on main
. try this:
angular
.module 'app', ['ui.router']
.run($state, $window) {
$window.onpopstate = function(event) {
var stateName = $state.current.name,
pathname = $window.location.pathname.split('/')[1],
routeParams = {}; // i.e.- $state.params
console.log($state.current.name, pathname); // 'main', 'folder'
if ($state.current.name.indexOf(pathname) === -1) {
// Optionally set option.notify to false if you don't want
// to retrigger another $stateChangeStart event
$state.go(
$state.current.name,
routeParams,
{reload:true, notify: false}
);
}
};
}
back/forward buttons should work smoothly after that.
note: check browser compatibility for window.onpopstate() to be sure
The same as @Nix with a small change to be strongly typed:
If you don't want to query for it just create an entity, and then delete it.
Customer customer = new Customer () { Id = id };
context.Customers.Attach(customer);
context.Customers.DeleteObject(customer);
context.SaveChanges();
Here sed
is replacing all occurrences of %
with $
in its standard input.
As an example
$ echo 'foo%bar%' | sed -e 's,%,$,g'
will produce "foo$bar$".
You've got the right idea, so here's how to go ahead: the onclick
handlers run on the client side, in the browser, so you cannot call a PHP function directly. Instead, you need to add a JavaScript function that (as you mentioned) uses AJAX to call a PHP script and retrieve the data. Using jQuery, you can do something like this:
<script type="text/javascript">
function recp(id) {
$('#myStyle').load('data.php?id=' + id);
}
</script>
<a href="#" onClick="recp('1')" > One </a>
<a href="#" onClick="recp('2')" > Two </a>
<a href="#" onClick="recp('3')" > Three </a>
<div id='myStyle'>
</div>
Then you put your PHP code into a separate file: (I've called it data.php
in the above example)
<?php
require ('myConnect.php');
$id = $_GET['id'];
$results = mysql_query("SELECT para FROM content WHERE para_ID='$id'");
if( mysql_num_rows($results) > 0 )
{
$row = mysql_fetch_array( $results );
echo $row['para'];
}
?>
The requests package has a very nice API for HTTP requests, adding a custom header works like this (source: official docs):
>>> import requests
>>> response = requests.get(
... 'https://website.com/id', headers={'Authorization': 'access_token myToken'})
If you don't want to use an external dependency, the same thing using urllib2 of the standard library looks like this (source: the missing manual):
>>> import urllib2
>>> response = urllib2.urlopen(
... urllib2.Request('https://website.com/id', headers={'Authorization': 'access_token myToken'})
One option from DOM directly:
$(document).find("title").text();
Tested only on chrome & IE9, but logically should work on all browsers.
Or more generic
var title = document.getElementsByTagName("title")[0].innerHTML;

For a quick fix to your problem, change your ;

If you want to know if "1" ou 1 can be casted to a number, you can use this code :
if (isNaN(i*1)) {
console.log('i is not a number');
}
You can use something like this
$(ssh -o BatchMode=yes -o ConnectTimeout=5 user@host echo ok 2>&1)
This will output "ok" if ssh connection is ok

There are two ways,
android:screenOrientation="portrait"
for each Activity in Manifest Filethis.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
in each java file.You can enter the following formula in the cell where you want to see the Overdue
or Not due
result:
=IF(ISBLANK(O10),"",IF(O10<TODAY(),"Overdue","Not due"))
This formula first tests if the source cell is blank. If it is, then the result cell will be filled with the empty string. If the source is not blank, then the formula tests if the date in the source cell is before the current day. If it is, then the value is set to Overdue
, otherwise it is set to Not due
.

BigJacko's Javascript code worked for me, but in my case I first had to add some JQuery "noconflict" code. Here's the revised version that worked on my site:
<script type="text/javascript">
var $j = jQuery.noConflict();
jQuery(document).ready(function($j){
$j('iframe').each(function() {
var url = $j(this).attr("src");
if ($j(this).attr("src").indexOf("?") > 0) {
$j(this).attr({
"src" : url + "&wmode=transparent",
"wmode" : "Opaque"
});
}
else {
$j(this).attr({
"src" : url + "?wmode=transparent",
"wmode" : "Opaque"
});
}
});
});
</script>

It sounds like you're trying to use log4j from "both ends" (the consumer end and the configuration end).
If you want to code against the slf4j api but determine ahead of time (and programmatically) the configuration of the log4j Loggers that the classpath will return, you absolutely have to have some sort of logging adaptation which makes use of lazy construction.
public class YourLoggingWrapper {
private static boolean loggingIsInitialized = false;
public YourLoggingWrapper() {
// ...blah
}
public static void debug(String debugMsg) {
log(LogLevel.Debug, debugMsg);
}
// Same for all other log levels your want to handle.
// You mentioned TRACE and ERROR.
private static void log(LogLevel level, String logMsg) {
if(!loggingIsInitialized)
initLogging();
org.slf4j.Logger slf4jLogger = org.slf4j.LoggerFactory.getLogger("DebugLogger");
switch(level) {
case: Debug:
logger.debug(logMsg);
break;
default:
// whatever
}
}
// log4j logging is lazily constructed; it gets initialized
// the first time the invoking app calls a log method
private static void initLogging() {
loggingIsInitialized = true;
org.apache.log4j.Logger debugLogger = org.apache.log4j.LoggerFactory.getLogger("DebugLogger");
// Now all the same configuration code that @oers suggested applies...
// configure the logger, configure and add its appenders, etc.
debugLogger.addAppender(someConfiguredFileAppender);
}
With this approach, you don't need to worry about where/when your log4j loggers get configured. The first time the classpath asks for them, they get lazily constructed, passed back and made available via slf4j. Hope this helped!
Now you should be able to sort by this column either Oldest to Newest or Newest to Oldest
Once you have the packages setup, you'll need to create either an app.config or web.config and add something like the following:
<configuration>
<appSettings>
<add key="key" value="value"/>
</appSettings>
</configuration>

You need to get the mouse position relative to the canvas
To do that you need to know the X/Y position of the canvas on the page.
This is called the canvas’s “offset”, and here’s how to get the offset. (I’m using jQuery in order to simplify cross-browser compatibility, but if you want to use raw javascript a quick Google will get that too).
var canvasOffset=$("#canvas").offset();
var offsetX=canvasOffset.left;
var offsetY=canvasOffset.top;
Then in your mouse handler, you can get the mouse X/Y like this:
function handleMouseDown(e){
mouseX=parseInt(e.clientX-offsetX);
mouseY=parseInt(e.clientY-offsetY);
}
Here is an illustrating code and fiddle that shows how to successfully track mouse events on the canvas:

Here is an Scheme version that constructs a function that will work against any base. It has a redundancy check: return false quickly if the number is a multiple of the base (ends in 0).
And it doesn't rebuild the entire reversed number, only half.
That's all we need.
(define make-palindrome-tester

(lambda (n)
(cond
((= 0 (modulo n base)) #f)
(else

((= h t) #t)
(else
(let*
((h2 (quotient h base))
(m (- h (* h2 base))))
(cond
((= h2 t) #t)
(else
(Q h2 (+ (* base t) m))))))))))
(Q n 0)))))))
DI is how real objects actually interact with each other without one object being responsible for the existence of another object. Objects should be treated in equality. They are all objects. No one should act like a creator. This is how you do justice to your objects.
Simple example:
if you need a physician, you simply go and find (an existing) one. You will not be thinking of creating a physician from scratch to help you. He already exists and he may serve you or other objects. He has the right to exist whether you (a single object) needs him or not because his purpose is to serve one or more objects. Who decided his existence is Almighty God, not natural selection. Therefore, one advantage of DI is to avoid creating useless redundant objects living without a purpose during the lifetime of your universe (i.e. application).
If you are using asp.net mvc, here is a simple way to access the session.
From a Controller:
{Controller}.ControllerContext.HttpContext.Session["{name}"]
From a View:
<%=Session["{name}"] %>
This is definitely not the best way to access your session variables, but it is a direct route. So use it with caution (preferably during rapid prototyping), and use a Wrapper/Container and OnSessionStart when it becomes appropriate.

I solved it. I had to drag the .cer files into KeyChain Access. But make sure "Login" is selected in the upper left. If not, Xcode will not see the cert and will not be able to sign your code.
Apple has some room for improvement in this department....
I tried many ways to send a mail from XAMPP Localhost, but since XAMPP hasn't SSL Certificate, my email request blocked by Gmail or similar SMTP Service providers.
Then I used MailHog for local smtp server, what you need to do is just run it. localhost:1025 is for smtp server, localhost:8025 is for mail server, where you can check the emails you sent.
here is my code:
require_once "src/PHPMailer.php";
require_once "src/SMTP.php";
require_once "src/Exception.php";
$mail = new PHPMailer\PHPMailer\PHPMailer();
//Server settings
$mail->SMTPDebug = 3; // Enable verbose debug output
$mail->isSMTP(); // Send using SMTP
$mail->Host = 'localhost'; // Set the SMTP server to send through
$mail->Port = 1025; // TCP port to connect to
// $mail->Username = ''; // SMTP username
// $mail->Password = ''; // SMTP password
// $mail->SMTPAuth = true; // Enable SMTP authentication
// $mail->SMTPSecure = 'tls'; // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` also accepted
//Recipients
$mail->setFrom('[email protected]', 'Mailer');
$mail->addAddress('[email protected]', 'Joe User'); // Add a recipient
// Content
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}
In Swift 4.1 and Xcode 9.4.1.

func yourFunctionName {
//Check internet connection
let networkReachability = Reachability.forInternetConnection()
let networkStatus:Int = (networkReachability?.currentReachabilityStatus())!.rawValue
print(networkStatus)
if networkStatus == NotReachable.rawValue {
let msg = SharedClass.sharedInstance.noNetMsg//Message
//Call alert from shared class
SharedClass.sharedInstance.alert(view: self, title: "", message: msg)
} else {
//Call spinner from shared class
SharedClass.sharedInstance.activityIndicator(view: self.view)//Play spinner
let parameters = "Your parameters here"
var request = URLRequest(url: URL(string: url)!)
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.httpMethod = "POST"
print("URL : \(request)")
request.httpBody = parameters.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { // check for fundamental networking error
//Stop spinner
SharedClass.sharedInstance.stopActivityIndicator() //Stop spinner
//Print error in alert
SharedClass.sharedInstance.alert(view: self, title: "", message: "\(String(describing: error!.localizedDescription))")
return
}
SharedClass.sharedInstance.stopActivityIndicator() //Stop spinner
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(String(describing: response))")
}
do {
let response = try JSONSerialization.jsonObject(with: data, options: []) as? [String: AnyObject]
print(response!)
//Your code here
} catch let error as NSError {
print(error)
}
}
task.resume()
}
}
If you have interest to use this function in SharedClass
//My shared class
import UIKit
class SharedClass: NSObject {
static let sharedInstance = SharedClass()
func postRequestFunction(apiName: String , parameters: String, onCompletion: @escaping (_ success: Bool, _ error: Error?, _ result: [String: Any]?)->()) {
var URL = "your URL here/index.php/***?"
URL = URL.replacingOccurrences(of: "***", with: apiName)
var request = URLRequest(url: URL(string: URL)!)
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.httpMethod = "POST"
print("shared URL : \(request)")
request.httpBody = parameters.data(using: .utf8)
var returnRes:[String:Any] = [:]
let task = URLSession.shared.dataTask(with: request) { data, response, error in
if let error = error {
onCompletion(false, error, nil)
} else {
guard let data = data else {
onCompletion(false, error, nil)
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode == 200 {
do {
returnRes = try JSONSerialization.jsonObject(with: data, options: []) as! [String : Any]
onCompletion(true, nil, returnRes)
} catch let error as NSError {
onCompletion(false, error, nil)
}
} else {
onCompletion(false, error, nil)
}
}
}
task.resume()
}
private override init() {
}
And finally call this function like this....
SharedClass.sharedInstance.postRequestFunction(apiName: "Your API name", parameters: parameters) { (success, error, result) in
print(result!)
if success {
//Your code here
} else {
print(error?.localizedDescription ?? "")
}
}
Serj-Tm solution is fine, also this is the generic version as extension method for lists (put it into a static class):
public static List<List<T>> Split<T>(this List<T> items, int sliceSize = 30)
{
List<List<T>> list = new List<List<T>>();
for (int i = 0; i < items.Count; i += sliceSize)
list.Add(items.GetRange(i, Math.Min(sliceSize, items.Count - i)));
return list;
}
Here is a plain JS and a jQuery plugin I wrote that will handle resizing an input element using a canvas and the font size / family to determine the actual string length when rendered. (only works in > IE9, chrome, safari, firefox, opera and most other major browsers that have implemented the canvas element).
PlainJS:
function autoSize(input, o) {
o || (o = {});
o.on || (o.on = 'keyup');
var canvas = document.createElement('canvas');
canvas.setAttribute('style', 'position: absolute; left: -9999px');
document.body.appendChild(canvas);
var ctx = canvas.getContext('2d');
input.addEventListener(o.on, function () {
ctx.font = getComputedStyle(this,null).getPropertyValue('font');
this.style.width = ctx.measureText(this.value + ' ').width + 'px';
});
}
//Usage
autoSize(document.getElementById('my-input'));
jQuery Plugin:
$.fn.autoSize = function(o) {
o = $.extend({}, {
on: 'keyup'
}, o);
var $canvas = $('<canvas/>').css({position: 'absolute', left: -9999});
$('body').append($canvas);
var ctx = $canvas[0].getContext('2d');
return this.on(o.on, function(){
var $this = $(this);
ctx.font = $this.css('font');
$this.width(ctx.measureText($this.val()).width + 'px');
})
}
//Usage:
$('#my-input').autoSize();
Note: this will not handle text-transforms, line spacing and letter spacing, and probably some other text size changing properties. To handle text-transform property set and adjust the text value to match that property. The others are probably fairly straight forward. I will implement if this starts gaining some traction...
Similar answer to iHulk's one, but in Swift
Add a file named UIView.swift in your project (or just paste this in any file) :
import UIKit
@IBDesignable extension UIView {
@IBInspectable var borderColor: UIColor? {
set {
layer.borderColor = newValue?.cgColor
}
get {
guard let color = layer.borderColor else {
return nil
}
return UIColor(cgColor: color)
}
}
@IBInspectable var borderWidth: CGFloat {
set {
layer.borderWidth = newValue
}
get {
return layer.borderWidth
}
}
@IBInspectable var cornerRadius: CGFloat {
set {
layer.cornerRadius = newValue
clipsToBounds = newValue > 0
}
get {
return layer.cornerRadius
}
}
}
Then this will be available in Interface Builder for every button, imageView, label, etc. in the Utilities Panel > Attributes Inspector :
Note: the border will only appear at runtime.
The other answers here are correct, but they don't get into how instanceof
actually works, which may be of interest to some language lawyers out there.
Every object in JavaScript has a prototype, accessible through the __proto__
property. Functions also have a prototype
property, which is the initial __proto__
for any objects created by them. When a function is created, it is given a unique object for prototype
. The instanceof
operator uses this uniqueness to give you an answer. Here's what instanceof
might look like if you wrote it as a function.
function instance_of(V, F) {
var O = F.prototype;
V = V.__proto__;
while (true) {
if (V === null)
return false;
if (O === V)
return true;
V = V.__proto__;
}
}
This is basically paraphrasing ECMA-262 edition 5.1 (also known as ES5), section 15.3.5.3.
Note that you can reassign any object to a function's prototype
property, and you can reassign an object's __proto__
property after it is constructed. This will give you some interesting results:
function F() { }
function G() { }
var p = {};
F.prototype = p;
G.prototype = p;
var f = new F();
var g = new G();
f instanceof F; // returns true
f instanceof G; // returns true
g instanceof F; // returns true
g instanceof G; // returns true
F.prototype = {};
f instanceof F; // returns false
g.__proto__ = {};
g instanceof G; // returns false
I think creating a class to simulate C-like structs, like you've been doing, is the best way.
It's a great way to group related data and simplifies passing parameters to functions. I'd also argue that a JavaScript class is more like a C++ struct than a C++ class, considering the added effort needed to simulate real object oriented features.
I've found that trying to make JavaScript more like another language gets complicated fast, but I fully support using JavaScript classes as functionless structs.
I just tried SMTPop and it worked.

I had this issue and I though that these answers didn't help then I figured out that my environment variables wasn't correct, although I was able to do sdkmanager
command anywhere, so make sure that the environment variable is set correctly:
In the environment variables define a new variable with
ANDROID_SDK_ROOT
as a name and give it a value of where the
sdktools are located eg.: C:\Android\sdk\
Edit your path to add the created variable to be
%ANDROID_SDK_ROOT%\tools\bin\
restart you cmd.
Run the command that where mentioned in the answers:
sdkmanager --licenses
Install the desired packages using sdkmanager "packageName"
.
I would like to recommend flask-empty at GitHub.
It provides an easy way to understand Blueprints, multiple views and extensions.
You can also try to use a Polyfill like Fixed-Sticky. Especially when you are using Bootstrap4 the affix
component is no longer included:
Dropped the Affix jQuery plugin. We recommend using a position: sticky polyfill instead.
I would recommend using an actual anchor element, and set it as block.
<div class="divBox">
<a href="#">Link</a>
</div>
.divBox
{
width: 300px;
height: 100px;
}
.divBox a
{
width: 100%;
height: 100%;
display: block;
}
This will set the anchor to the same dimensions of the parent div.
You can try a list comp
>>> exampleSet = [{'type':'type1'},{'type':'type2'},{'type':'type2'}, {'type':'type3'}]
>>> keyValList = ['type2','type3']
>>> expectedResult = [d for d in exampleSet if d['type'] in keyValList]
>>> expectedResult
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]
Another way is by using filter
>>> list(filter(lambda d: d['type'] in keyValList, exampleSet))
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]
For me, the following works (mostly inspirated from all of the following answers), I started from Elad's answer and modify/simplify things to match my need (remove not file form inputs, only one file, ...).
Hope it can helps somebody :)
(PS: I know that exception handling is not implemented and it assumes that it was written inside a class, so I may need some integration effort...)

EDIT: I've added one more option for bootstrap sidebars.
There are actually three manners in which you can make a bootstrap 3 sidebar. I tried to keep the code as simple as possible.
Here you can see a demo of a simple fixed sidebar I've developed with the same height as the page
I've also developed a rather simple column sidebar that works in a two or three column page inside a container. It takes the length of the longest column. Here you can see a demo
If you google bootstrap dashboard, you can find multiple suitable dashboard, such as this one. However, most of them require a lot of coding. I've developed a dashboard that works without additional javascript (next to the bootstrap javascript). Here is a demo
For all three examples you off course have to include the jquery, bootstrap css, js and theme.css files.
If you want the sidebar to hide on pressing a button this is also possible with only a little javascript.Here is a demo
var oldDateObj = new Date();_x000D_
var newDateObj = new Date();_x000D_
newDateObj.setTime(oldDateObj.getTime() + (30 * 60 * 1000));_x000D_
console.log(newDateObj);
_x000D_
Add bean declaration in bean.xml file or in any other configuration file . It will resolve the error

In general, you can't do this in any straightforward fashion. time_point
is essentially just a duration
from a clock-specific epoch.
If you have a std::chrono::system_clock::time_point
, then you can use std::chrono::system_clock::to_time_t
to convert the time_point
to a time_t
, and then use the normal C functions such as ctime
or strftime
to format it.
Example code:
std::chrono::system_clock::time_point tp = std::chrono::system_clock::now();
std::time_t time = std::chrono::system_clock::to_time_t(tp);
std::tm timetm = *std::localtime(&time);
std::cout << "output : " << std::put_time(&timetm, "%c %Z") << "+"
<< std::chrono::duration_cast<std::chrono::milliseconds>(tp.time_since_epoch()).count() % 1000 << std::endl;

See the docs for to_dict
. You can use it like this:
df.set_index('id').to_dict()
And if you have only one column, to avoid the column name is also a level in the dict (actually, in this case you use the Series.to_dict()
):
df.set_index('id')['value'].to_dict()
@phanhuy152 has the best answer. Just to add my two cents:
His solution is:
migrations
foldermakemigrations
to restore the initial state of the migration filesmakemigrations
againmigrate
to apply updates to table.But in my case, I have several models in the models.py
file and at the last step, Django complains about Table xxx already exists
, because the initial migrations files intends to create the xxx table again, when we just don't (and don't want to)drop other tables.
In this case, in order to preserve the data, we must tell Django to leave them alone in migrate
. We just do: (assume that class A is the one we change, and class B, C remain same):
models.py
:
from django.db import models
class A(models.Models):
...
class B(models.Models):
class Meta:
managed = False # tell Django to leave this class alone
...
class C(models.Models):
class Meta:
managed = False # tell Django to leave this class alone
Add these lines after we construct the initial migrations.
So, the process now is:
managed = False
to other classesmakemigrations
to apply Meta
changes. You will see something like:output:
Migrations for 'backEnd':
backEnd/migrations/0002_auto_20180412_1654.py
- Change Meta options on toid
- Change Meta options on tprocessasinc
- Change Meta options on tservers
- Change Meta options on tsnmpserver
migrate
to apply them in DBmigrate
again.Meta
class to let Django manage other class again. makemigrations
, migrate
again.Now you have all the structure and data of your models, without losing the part formerly stored in DB.
Perhaps use plt.annotate:
import numpy as np
import matplotlib.pyplot as plt
N = 10

For Android development, I use:
int color = Color.parseColor("#123456");
Simply use
java.util.Collections.sort(list)
without String.CASE_INSENSITIVE_ORDER comparator parameter.
The trick to using display:none with images is to assign them an id. This was there is not a lot of code needed to make it work. Here is an example using media queries and 3 stylesheets. One for phone, one for tablet, and one for desktop. I have 3 images, image of a phone, a tablet, and a desktop. On a phone screen only an image of the phone will display, a tablet will display only the tablet image, a desktop displays on the desktop computer image. Here is a code example to make it work:
Source code:
<div id="content">
<img id="phone" src="images/phone.png" />
<img id="tablet" src="images/tablet.png" />
<img id="desktop" src="images/desktop.png" />
</div>
The phone CSS which doesn't need a media query. Its the img#phone that makes it work:
img#phone {
display: block;
margin: 6em auto 0 auto;
width: 70%;
}
img#tablet {display: none;}
img#desktop {display: none;}
The tablet css:
@media only screen and (min-width: 641px) {
img#phone {display: none;}
img#tablet {
display: block;
margin: 6em auto 0 auto;
width: 70%;
}
}
And the desktop css:
@media only screen and (min-width: 1141px) {
img#tablet {display: none;}
img#desktop {
display: block;
margin: 6em auto 0 auto;
width: 80%;
}
}
Good luck and let me know how it works for you.
Just get rid of the parenthesis and that will give you an array with one element and:
var test = tesst.match(/a(.*)j/);
var test = tesst.match(/a.*j/);
If you add parenthesis the match() function will find two match for you one for whole expression and one for the expression inside the parenthesis
If you only want the first match found, you might want to use RegExp.exec() instead.
You can use the below code:
RegExp(/a.*j/).exec("afskfsd33j")
Content inside a <div class='html-content'>....</div>
can be downloaded as pdf with styles using jspdf & html2canvas.
You need to refer both js libraries,
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.5.3/jspdf.min.js"></script>
<script type="text/javascript" src="https://html2canvas.hertzen.com/dist/html2canvas.js"></script>
Then call below function,
//Create PDf from HTML...
function CreatePDFfromHTML() {
var HTML_Width = $(".html-content").width();
var HTML_Height = $(".html-content").height();
var top_left_margin = 15;
var PDF_Width = HTML_Width + (top_left_margin * 2);
var PDF_Height = (PDF_Width * 1.5) + (top_left_margin * 2);
var canvas_image_width = HTML_Width;
var canvas_image_height = HTML_Height;
var totalPDFPages = Math.ceil(HTML_Height / PDF_Height) - 1;
html2canvas($(".html-content")[0]).then(function (canvas) {
var imgData = canvas.toDataURL("image/jpeg", 1.0);
var pdf = new jsPDF('p', 'pt', [PDF_Width, PDF_Height]);
pdf.addImage(imgData, 'JPG', top_left_margin, top_left_margin, canvas_image_width, canvas_image_height);
for (var i = 1; i <= totalPDFPages; i++) {
pdf.addPage(PDF_Width, PDF_Height);
pdf.addImage(imgData, 'JPG', top_left_margin, -(PDF_Height*i)+(top_left_margin*4),canvas_image_width,canvas_image_height);
}
pdf.save("Your_PDF_Name.pdf");
$(".html-content").hide();
});
}

May be this will help someone.
You can limit the number of lines, or arguments (if there are spaces between each argument) using the --max-lines or --max-args flags, respectively.
-L max-lines Use at most max-lines nonblank input lines per command line. Trailing blanks cause an input line to be logically continued on the next input line. Implies -x. --max-lines[=max-lines], -l[max-lines] Synonym for the -L option. Unlike -L, the max-lines argument is optional. If max-args is not specified, it defaults to one. The -l option is deprecated since the POSIX standard specifies -L instead. --max-args=max-args, -n max-args Use at most max-args arguments per command line. Fewer than max-args arguments will be used if the size (see the -s option) is exceeded, unless the -x option is given, in which case xargs will exit.
As mentioned here, uou can use matplotlib.pyplot.text
objects in order to achieve the same result:
plt.text(x=0.5, y=0.94, s="My title 1", fontsize=18, ha="center", transform=fig.transFigure)
plt.text(x=0.5, y=0.88, s= "My title 2 in different size", fontsize=12, ha="center", transform=fig.transFigure)
plt.subplots_adjust(top=0.8, wspace=0.3)
If you want to secure your API in a server to server fashion (no redirection to website for 2 legged authentication). You can look at OAuth2 Client Credentials Grant protocol.
https://dev.twitter.com/docs/auth/application-only-auth
I have developed a library that can help you easily add this kind of support to your WebAPI. You can install it as a NuGet package:
https://nuget.org/packages/OAuth2ClientCredentialsGrant/1.0.0.0
The library targets .NET Framework 4.5.
Once you add the package to your project, it will create a readme file in the root of your project. You can look at that readme file to see how to configure/use this package.
Cheers!

For anyone using Koa and koa-passport:
Know that the key for the user set in the serializeUser method (often a unique id for that user) will be stored in:
this.session.passport.user
When you set in done(null, user)
in deserializeUser where 'user' is some user object from your database:
this.req.user
OR
this.passport.user
for some reason this.user
Koa context never gets set when you call done(null, user) in your deserializeUser method.
So you can write your own middleware after the call to app.use(passport.session()) to put it in this.user like so:
app.use(function * setUserInContext (next) {
this.user = this.req.user
yield next
})
If you're unclear on how serializeUser and deserializeUser work, just hit me up on twitter. @yvanscher
You are both using closures.
I 'm going with the Wikipedia definition here:
In computer science, a closure (also lexical closure or function closure) is a function or reference to a function together with a referencing environment—a table storing a reference to each of the non-local variables (also called free variables) of that function. A closure—unlike a plain function pointer—allows a function to access those non-local variables even when invoked outside of its immediate lexical scope.
Your friend's attempt clearly uses the variable i
, which is non-local, by taking its value and making a copy to store into the local i2
.
Your own attempt passes i
(which at the call site is in scope) to an anonymous function as an argument. This is not a closure so far, but then that function returns another function that references the same i2
. Since inside the inner anonymous function i2
is not a local, this creates a closure.
I'll answer my own question for the first time. I found an example straight from the source. Please forgive the poor indentation. I wasn't sure how to indent properly when copying and pasting. The code comes straight from Express multipart/form-data
example on GitHub.
// Expose modules in ./support for demo purposes
require.paths.unshift(__dirname + '/../../support');
/**
* Module dependencies.
*/
var express = require('../../lib/express')
, form = require('connect-form');
var app = express.createServer(
// connect-form (http://github.com/visionmedia/connect-form)
// middleware uses the formidable middleware to parse urlencoded
// and multipart form data
form({ keepExtensions: true })
);
app.get('/', function(req, res){
res.send('<form method="post" enctype="multipart/form-data">'
+ '<p>Image: <input type="file" name="image" /></p>'
+ '<p><input type="submit" value="Upload" /></p>'
+ '</form>');
});
app.post('/', function(req, res, next){
// connect-form adds the req.form object
// we can (optionally) define onComplete, passing
// the exception (if any) fields parsed, and files parsed
req.form.complete(function(err, fields, files){
if (err) {
next(err);
} else {
console.log('\nuploaded %s to %s'
, files.image.filename
, files.image.path);
res.redirect('back');
}
});
// We can add listeners for several form
// events such as "progress"
req.form.on('progress', function(bytesReceived, bytesExpected){
var percent = (bytesReceived / bytesExpected * 100) | 0;
process.stdout.write('Uploading: %' + percent + '\r');
});
});
app.listen(3000);
console.log('Express app started on port 3000');
Below are the working steps without the need for any external modules:
Step 1: Create a module in your app.
E.g, lets assume we have an app called user_registration_app. Explore user_registration_app and create a new file.
Lets call this as custom_cors_middleware.py
Paste the below Class definition:
class CustomCorsMiddleware:
def __init__(self, get_response):
self.get_response = get_response
# One-time configuration and initialization.
def __call__(self, request):
# Code to be executed for each request before
# the view (and later middleware) are called.
response = self.get_response(request)
response["Access-Control-Allow-Origin"] = "*"
response["Access-Control-Allow-Headers"] = "*"
# Code to be executed for each request/response after
# the view is called.
return response
Step 2: Register a middleware
In your projects settings.py file, add this line
'user_registration_app.custom_cors_middleware.CustomCorsMiddleware'
E.g:
MIDDLEWARE = [
'user_registration_app.custom_cors_middleware.CustomCorsMiddleware', # ADD THIS LINE BEFORE CommonMiddleware
...
'django.middleware.common.CommonMiddleware',
]
Remember to replace user_registration_app with the name of your app where you have created your custom_cors_middleware.py module.
You can now verify it will add the required response headers to all the views in the project!
