You can do it this way:
Declare interface:
public interface MyInterface{
public void foo();
}
Let your Activity imlement it:
public class MyActivity extends Activity implements MyInterface{
public void foo(){
//do stuff
}
public onCreate(){
//your code
MyAdapter adapter = new MyAdapter(this); //this will work as your
//MyInterface listener
}
}
Then pass your activity to ListAdater:
public MyAdapter extends BaseAdater{
private MyInterface listener;
public MyAdapter(MyInterface listener){
this.listener = listener;
}
}
And somewhere in adapter, when you need to call that Activity method:
listener.foo();
For those using OpenSSL you can retrieve the SHA1 fingerprint this way:
OpenSSL> dgst -sha1 my-release-key.keystore
Which would result in the following output:

You can also now have it auto-open Developer Tools in Pop-ups if they were open where you opened them from. For example, if you do not have Dev Tools open and you get a popup, it won't open with Dev Tools. But if you Have Dev Tools Open and then you click something, the popup will have Dev-Tools Automatically opened.
UPDATE:
Time has changed, you can now use --auto-open-devtools-for-tabs as in this answer – Wouter Huysentruit May 18 at 11:08
OP:
I played around with the startup string for Chrome on execute, but couldn't get it to persist to new tabs.
I also thought about a defined PATH method that you could invoke from prompt. This is possible with the SendKeys command, but again, only on a new instance. And DevTools doesn't persist to new tabs.
Browsing the Google Product Forums, there doesn't seem to be a built-in way to do this in Chrome. You'll have to use a keystroke solution or F12 as mentioned above.
I recommended it as a feature. I know I'm not the first either.
OK, so thanks to all of the contributors above. I am using .NET 4.6 and we also had the same issue. I spent time debugging System.Net.Http
, specifically the HttpClientHandler
, and found the following:
if (ExecutionContext.IsFlowSuppressed())
{
IWebProxy webProxy = (IWebProxy) null;
if (this.useProxy)
webProxy = this.proxy ?? WebRequest.DefaultWebProxy;
if (this.UseDefaultCredentials || this.Credentials != null || webProxy != null && webProxy.Credentials != null)
this.SafeCaptureIdenity(state);
}
So after assessing that the ExecutionContext.IsFlowSuppressed()
might have been the culprit, I wrapped our Impersonation code as follows:
using (((WindowsIdentity)ExecutionContext.Current.Identity).Impersonate())
using (System.Threading.ExecutionContext.SuppressFlow())
{
// HttpClient code goes here!
}
The code inside of SafeCaptureIdenity
(not my spelling mistake), grabs WindowsIdentity.Current()
which is our impersonated identity. This is being picked up because we are now suppressing flow. Because of the using/dispose this is reset after invocation.
It now seems to work for us, phew!
Based on what Janek answered, this worked for me (Linux):
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("--start-maximized")
driver = webdriver.Chrome(chrome_options=options)
see this page Entity Framework and AsNoTracking
Entity Framework exposes a number of performance tuning options to help you optimise the performance of your applications. One of these tuning options is .AsNoTracking()
. This optimisation allows you to tell Entity Framework
not to track the results of a query. This means that Entity Framework
performs no additional processing or storage of the entities which are returned by the query. However, it also means that you can't update these entities without reattaching them to the tracking graph.
there are significant performance gains to be had by using AsNoTracking
When you want to destroy a session completely, you need to do more then just
session_destroy();
First, you should unset any session variables. Then you should destroy the session followed by closing the write of the session. This can be done by the following:
<?php
session_start();
unset($_SESSION);
session_destroy();
session_write_close();
header('Location: /');
die;
?>
The reason you want have a separate script for a logout is so that you do not accidently execute it on the page. So make a link to your logout script, then the header will redirect to the root of your site.
Edit:
You need to remove the () from your exit code near the top of your script. it should just be
exit;
If you download Java Development Kit(JDK) then there is a difference as it contains native libraries which differ for different architectures:
In addition you can use 32-bit JDK(x86) on 64-bit OS. But you can not use 64-bit JDK on 32-bit OS.
At the same time you can run compiled Java classes on any JVM. It does not matter whether it 32 or 64-bit.
I came across the same issue. My service is uploading/receiving XMLS and write the errors to the Event Log.
When I went to the Event Log, I tried to filter it. It prompt me that the Event Log was corrupted.
I cleared the Event Log and all OK.
To answer the question literally (since GitHub is not in the question title), also be aware of this post over on superuser. EDIT: Answer copied here in relevant part, slightly modified for clarity in square brackets:
You're getting rejected because you're trying to delete the branch that your origin has currently "checked out".
If you have direct access to the repo, you can just open up a shell [in the bare repo] directory and use good old
git branch
to see what branch origin is currently on. To change it to another branch, you have to usegit symbolic-ref HEAD refs/heads/another-branch
.
I guess the thread that needs to be killed is either in any kind of waiting mode, or doing some heavy job. I would suggest using a "naive" way.
Define some global boolean:
std::atomic_bool stop_thread_1 = false;
Put the following code (or similar) in several key points, in a way that it will cause all functions in the call stack to return until the thread naturally ends:
if (stop_thread_1)
return;
Then to stop the thread from another (main) thread:
stop_thread_1 = true;
thread1.join ();
stop_thread_1 = false; //(for next time. this can be when starting the thread instead)
The answer provided by @DSM is simple and straightforward, but I thought I'd add my own input to this question. If you look at the code for pandas.value_counts, you'll see that there is a lot going on.
If you need to calculate the frequency of many series, this could take a while. A faster implementation would be to use numpy.unique with return_counts = True
Here is an example:
import pandas as pd
import numpy as np
my_series = pd.Series([1,2,2,3,3,3])
print(my_series.value_counts())
3 3
2 2
1 1
dtype: int64
Notice here that the item returned is a pandas.Series
In comparison, numpy.unique
returns a tuple with two items, the unique values and the counts.
vals, counts = np.unique(my_series, return_counts=True)
print(vals, counts)
[1 2 3] [1 2 3]
You can then combine these into a dictionary:
results = dict(zip(vals, counts))
print(results)
{1: 1, 2: 2, 3: 3}
And then into a pandas.Series
print(pd.Series(results))
1 1
2 2
3 3
dtype: int64
You should use:
card_value= array.eq(i).val(); //gets jquery object at index i
or
card_value= array[i].value; //gets dom element at index i
For optimal Insertion performance disable the index if that's an option for you. Other than that, better hardware (disk, memory) is also helpful

We usually use One Main Window
for the application and other windows can be used in situations like when you need popups because instead of using popup controls in XAML which are not visible we can use a Window that is visible at design time so that'll be easy to work with
on the other hand we use many pages to navigate from one screen to another like User management screen to Order Screen etc In the main Window we can use Frame
control for navigation like below
XAML
<Frame Name="mainWinFrame" NavigationUIVisibility="Hidden" ButtonBase.Click="mainWinFrame_Click">
</Frame>
C#
private void mainWinFrame_Click(object sender, RoutedEventArgs e)
{
try
{
if (e.OriginalSource is Button)
{
Button btn = (Button)e.OriginalSource;
if ((btn.CommandParameter != null) && (btn.CommandParameter.Equals("Order")))
{
mainWinFrame.Navigate(OrderPage);
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Error");
}
}
That's one way of doing it We can also use a Tab Control instead of Fram and Add pages to it using a Dictionary while adding new page check if the control already exists then only navigate otherwise add and navigate. I hope that'll help someone
Try this:
input.focus();
input.scrollIntoView()
Another one is to use the -F option but pass it regex to print the text between left and or right parenthesis ()
.
The file content:
528(smbw)
529(smbt)
530(smbn)
10115(smbs)
The command:
awk -F"[()]" '{print $2}' filename
result:
smbw
smbt
smbn
smbs
Using awk to just print the text between []
:
Use awk -F'[][]'
but awk -F'[[]]'
will not work.

I had to use strcpy_s and it worked.
#include "stdafx.h"
#include<iostream>
#include<string>
using namespace std;
struct student
{
char name[30];
int age;
};
int main()
{
struct student s1;
char myname[30] = "John";
strcpy_s (s1.name, strlen(myname) + 1 ,myname );
s1.age = 21;
cout << " Name: " << s1.name << " age: " << s1.age << endl;
return 0;
}
sshpass
with better securityI stumbled on this thread while looking for a way to ssh into a bogged-down server -- it took over a minute to process the SSH connection attempt, and timed out before I could enter a password. In this case, I wanted to be able to supply my password immediately when the prompt was available.
(And if it's not painfully clear: with a server in this state, it's far too late to set up a public key login.)
sshpass
to the rescue. However, there are better ways to go about this than sshpass -p
.
My implementation skips directly to the interactive password prompt (no time wasted seeing if public key exchange can happen), and never reveals the password as plain text.
#!/bin/sh
# preempt-ssh.sh
# usage: same arguments that you'd pass to ssh normally
echo "You're going to run (with our additions) ssh $@"
# Read password interactively and save it to the environment
read -s -p "Password to use: " SSHPASS
export SSHPASS
# have sshpass load the password from the environment, and skip public key auth
# all other args come directly from the input
sshpass -e ssh -o PreferredAuthentications=keyboard-interactive -o PubkeyAuthentication=no "$@"
# clear the exported variable containing the password
unset SSHPASS
In my experience, /var/www/ directory directive prevents subfolder virtualhost directives. So if you had tried all suggestions and still not working and you are using virtualhosts try this ;
1 - Be sure that you have
AllowOverride All
directive in
/etc/apache2/sites-available/example.com.conf
2 - Check /var/www/ Directory directives in /etc/apache2/apache2.conf
(possibly at line 164), which looks like ;
<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
If there is an AllowOverride None
directive change it to
AllowOverride All
or just escape line
See http://wiki.apache.org/httpd/DistrosDefaultLayout for discussion of where you might find Apache httpd configuration files on various platforms, since this can vary from release to release and platform to platform. The most common answer, however, is either /etc/apache/conf or /etc/httpd/conf
Generically, you can determine the answer by running the command:
httpd -V
(That's a capital V). Or, on systems where httpd is renamed, perhaps apache2ctl -V
This will return various details about how httpd is built and configured, including the default location of the main configuration file.
One of the lines of output should look like:
-D SERVER_CONFIG_FILE="conf/httpd.conf"
which, combined with the line:
-D HTTPD_ROOT="/etc/httpd"
will give you a full path to the default location of the configuration file
os.listdir()
to see the list of files in the current working directoryos.getcwd()
(if you launch your code from an IDE, you may well be in a different directory)os.chdir(dir)
, dir
being the folder where the file is
located, then open the file with just its name like you were doing.open
call.dir = r'C:\Python32'
'C:\\User\\Bob\\...'
'C:/Python32'
and do not need to be escaped.Let me clarify how Python finds files:
working directory
. You can view Python's current working directory by calling os.getcwd()
. If you try to do open('sortedLists.yaml')
, Python will see that you are passing it a relative path, so it will search for the file inside the current working directory. Calling os.chdir
will change the current working directory.
Example: Let's say file.txt
is found in C:\Folder
.
To open it, you can do:
os.chdir(r'C:\Folder')
open('file.txt') #relative path, looks inside the current working directory
or
open(r'C:\Folder\file.txt') #full path
For bootstrap 3 example above works but is overcomplicated, rather than using form-group use form-inline for the fields you want inline.
Eg:
<div class="form-group">
<label>CVV</label>
<input type="text" size="4" class="form-control" />
</div>
<div class="form-inline">
<label>Expiration (MM/YYYY)</label><br>
<input type="text" size="2" class="form-control" /> / <input type="text" size="4" class="form-control" />
</div>
Three of the suggested methods were tested for speed with 1000 RGBA PNG images (224 x 256 pixels) running with Python 3.5 on Ubuntu 16.04 LTS (Xeon E5 2670 with SSD).
Average run times
pil :
1.037 seconds
scipy:
1.040 seconds
sk :
2.120 seconds
PIL and SciPy gave identical numpy
arrays (ranging from 0 to 255). SkImage gives arrays from 0 to 1. In addition the colors are converted slightly different, see the example from the CUB-200 dataset.

This is because the .pubxml.user contains required information to publish, and that file isn't (and shouldn't) be included in source control. To fix this VS bug, copy the information from the .pubxml.user file to the .pubxml file. The relevant properties are:
<LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration>
<LastUsedPlatform>Any CPU</LastUsedPlatform>
Put those in your .pubxml and you should be good to go.
A While
/Wend
loop can only be exited prematurely with a GOTO
or by exiting from an outer block (Exit sub
/function
or another exitable loop)
Change to a Do
loop instead:
Do While True
count = count + 1
If count = 10 Then
Exit Do
End If
Loop
Or for looping a set number of times:
for count = 1 to 10
msgbox count
next
(Exit For
can be used above to exit prematurely)
I ran into something similar - I wanted to create a range based on some variables. Using the Worksheet.Cells did not work directly since I think the cell's values were passed to Range.
This did work though:
Range(Cells(1, 1).Address(), Cells(lastRow, lastColumn).Address()).Select
That took care of converting the cell's numerical location to what Range expects, which is the A1 format.
Please try the following code below:
//Here I am using a reader object to fetch data from database, along with sqlcommand onject (cmd).
//Once the data is loaded to the Datatable object (datatable) you can loop through it using the datatable.rows.count prop.
using (reader = cmd.ExecuteReader())
{
// Load the Data table object
dataTable.Load(reader);
if (dataTable.Rows.Count > 0)
{
DataColumn col = dataTable.Columns["YourColumnName"];
foreach (DataRow row in dataTable.Rows)
{
strJsonData = row[col].ToString();
}
}
}
I used this method to load a script file dynamically (inside a controller).
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = "https://maps.googleapis.com/maps/api/js";
document.body.appendChild(script);
As for ERRORCODE 39, you can definately just delete the physical table files on the disk. the location depends on your OS distribution and setup. On Debian its typically under /var/lib/mysql/database_name/ So do a:
rm -f /var/lib/mysql/<database_name>/
And then drop the database from your tool of choice or using the command:
DROP DATABASE <database_name>

I found this answer here: https://dba.stackexchange.com/questions/1558. In short using the following (or within my.cnf) will remove the timeout issue.
SET GLOBAL interactive_timeout = 180;
SET GLOBAL wait_timeout = 180;
This allows the connections to end if they remain in a sleep State for 3 minutes (or whatever you define).

tryCatch
tryCatch
returns the value associated to executing expr
unless there's an error or a warning. In this case, specific return values (see return(NA)
above) can be specified by supplying a respective handler function (see arguments error
and warning
in ?tryCatch
). These can be functions that already exist, but you can also define them within tryCatch()
(as I did above).
The implications of choosing specific return values of the handler functions
As we've specified that NA
should be returned in case of error, the third element in y
is NA
. If we'd have chosen NULL
to be the return value, the length of y
would just have been 2
instead of 3
as lapply()
will simply "ignore" return values that are NULL
. Also note that if you don't specify an explicit return value via return()
, the handler functions will return NULL
(i.e. in case of an error or a warning condition).
"Undesired" warning message
As warn=FALSE
doesn't seem to have any effect, an alternative way to suppress the warning (which in this case isn't really of interest) is to use
suppressWarnings(readLines(con=url))
instead of
readLines(con=url, warn=FALSE)
Multiple expressions
Note that you can also place multiple expressions in the "actual expressions part" (argument expr
of tryCatch()
) if you wrap them in curly brackets (just like I illustrated in the finally
part).
Bundling is all about compressing several JavaScript or stylesheets files without any formatting (also referred as minified) into a single file for saving bandwith and number of requests to load a page.
As example you could create your own bundle:
bundles.Add(New ScriptBundle("~/bundles/mybundle").Include(
"~/Resources/Core/Javascripts/jquery-1.7.1.min.js",
"~/Resources/Core/Javascripts/jquery-ui-1.8.16.min.js",
"~/Resources/Core/Javascripts/jquery.validate.min.js",
"~/Resources/Core/Javascripts/jquery.validate.unobtrusive.min.js",
"~/Resources/Core/Javascripts/jquery.unobtrusive-ajax.min.js",
"~/Resources/Core/Javascripts/jquery-ui-timepicker-addon.js"))
And render it like this:
@Scripts.Render("~/bundles/mybundle")
One more advantage of @Scripts.Render("~/bundles/mybundle")
over the native <script src="~/bundles/mybundle" />
is that @Scripts.Render()
will respect the web.config
debug setting:
<system.web>
<compilation debug="true|false" />
If debug="true"
then it will instead render individual script tags for each source script, without any minification.
For stylesheets you will have to use a StyleBundle and @Styles.Render().
Instead of loading each script or style with a single request (with script or link tags), all files are compressed into a single JavaScript or stylesheet file and loaded together.
If your application is a Java EE application running on Oracle WebLogic as the application server, a possible cause for this issue is the Statement Cache Size setting in WebLogic.
If the Statement Cache Size setting for a particular data source is about equal to, or greater than, the Oracle database maximum open cursor count setting, then all of the open cursors can be consumed by cached SQL statements that are held open by WebLogic, resulting in the ORA-01000 error.
To address this, reduce the Statement Cache Size setting for each WebLogic datasource that points to the Oracle database to be significantly less than the maximum cursor count setting on the database.
In the WebLogic 10 Admin Console, the Statement Cache Size setting for each data source can be found at Services (left nav) > Data Sources > (individual data source) > Connection Pool tab.
I think the params
config parameter won't work here since it adds the string to the url instead of the body but to add to what Infeligo suggested here is an example of the global override of a default transform (using jQuery param as an example to convert the data to param string).
Set up global transformRequest function:
var app = angular.module('myApp');
app.config(function ($httpProvider) {
$httpProvider.defaults.transformRequest = function(data){
if (data === undefined) {
return data;
}
return $.param(data);
}
});
That way all calls to $http.post will automatically transform the body to the same param format used by the jQuery $.post
call.
Note you may also want to set the Content-Type header per call or globally like this:
$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8';
Sample non-global transformRequest per call:
var transform = function(data){
return $.param(data);
}
$http.post("/foo/bar", requestData, {
headers: { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'},
transformRequest: transform
}).success(function(responseData) {
//do stuff with response
});
Seems it is because modal animation is enabled (fade
in class of the dialog), after calling .modal('show')
, the dialog is not immediately visible, so it can't get focus at this time.
I can think of two ways to solve this problem:
fade
from class, so the dialog is immediately visible after calling .modal('show')
. You can see http://codebins.com/bin/4ldqp7x/4 for demo. (Sorry @keyur, I mistakenly edited and saved as new version of your example)focus()
in shown
event like what @keyur wrote.I don't think you can do this. Basic answers will work in many cases, and in others cause data corruptions. A strategy needs to be chosen based on heuristic analysis of your database. That is the reason this feature was implemented, and then removed. [doc]
You'll need to dump all object types in that database, create the newly named one and then import the dump. If this is a live system you'll need to take it down. If you cannot, then you will need to setup replication from this database to the new one.
If you want to see the commands that could do this, @satishD has the details, which conveys some of the challenges around which you'll need to build a strategy that matches your target database.
Also, if someone need the Infs' coordinates, can do this:
library(rlist)
list.clean(apply(df, 2, function(x){which(is.infinite(x))}), function(x) length(x) == 0L, TRUE)
Result:
$colname1
[1] row1 row2 ...
$colname2
[2] row1 row2 ...
With this information, you can replace the Inf values in particular places with the mean, median, or whatever operator that you want.
For example (for element 01):
repInf = list.clean(apply(df, 2, function(x){which(is.infinite(x))}), function(x) length(x) == 0L, TRUE)
df[repInf[[1]], names(repInf)[[1]]] = median or mean(is.finite(df[ ,names(repInf)[[1]]]), na.rm = TRUE)
In loop:
for (nonInf in 1:length(repInf)) {
df[repInf[[nonInf]], names(repInf)[[nonInf]]] = mean(is.finite(df[ , names(repInf)[[nonInf]]]))
}
Taking a guess at the results you want so maybe this is the query you want then
SELECT DISTINCT a FROM my_table
UNION
SELECT DISTINCT b FROM my_table
UNION
SELECT DISTINCT c FROM my_table
UNION
SELECT DISTINCT d FROM my_table
The simplest way would be to add the pull-left
class to your dropdown-submenu

Though an old question, I would like to add that currently mock
library (backport of unittest.mock) supports assert_not_called
method.
Just upgrade yours;
pip install mock --upgrade
Now on the Smartgit webpage (I don't know since when) there is the possibility to download directly the .deb package. Once installed, it will upgrade automagically itself when a new version is released.
Use File.ReadAllText(path_to_file)

This should not work in C++:
Days.Saturday
Days is not a scope or object that contains members you can access with the dot operator. This syntax is just a C#-ism and is not legal in C++.
Microsoft has long maintained a C++ extension that allows you to access the identifiers using the scope operator:
enum E { A, B, C };
A;
E::B; // works with Microsoft's extension
But this is non-standard before C++11. In C++03 the identifiers declared in an enum exist only in the same scope as the enum type itself.
A;
E::B; // error in C++03
C++11 makes it legal to qualify enum identifiers with the enum name, and also introduces enum classes, which create a new scope for the identifiers instead of placing them in the surrounding scope.
A;
E::B; // legal in C++11
enum class F { A, B, C };
A; // error
F::B;
Series.apply(func, convert_dtype=True, args=(), **kwds)
args : tuple
x = my_series.apply(my_function, args = (arg1,))
This is a revised solution that will also work for modal windows rendered using a Grails template, where you can have the same modal template called multiple times (with different values) in the same body. This thread helped me immensely, so I thought I'd share it in case other Grails users found their way here.
For those who are curious, the accepted solution didn't work for me because I am rendering a table; each row has a button that opens a modal window with more details about the record. This led to multiple printSection divs being created and printed on top of each other. Therefore I had to revise the js to clean up the div after it was done printing.
I added this CSS directly to my modal gsp, but adding it to the parent has the same effect.
<style type="text/css">
@media screen {
#printSection {
display: none;
}
}
@media print {
body > *:not(#printSection) {
display: none;
}
#printSection, #printSection * {
visibility: visible;
}
#printSection {
position:absolute;
left:0;
top:0;
}
}
</style>
Adding it to the site-wide CSS killed the print functionality in other parts of the site. I got this from ComFreak's accepted answer (based on Bennett McElwee answer), but it is revised using ':not' functionality from fanfavorite's answer on Print <div id=printarea></div> only? . I opted for 'display' rather than 'visibility' because my invisible body content was creating extra blank pages, which was unacceptable to my users.
And this to my javascript, revised from ComFreak's accepted answer to this question.
function printDiv(div) {
// Create and insert new print section
var elem = document.getElementById(div);
var domClone = elem.cloneNode(true);
var $printSection = document.createElement("div");
$printSection.id = "printSection";
$printSection.appendChild(domClone);
document.body.insertBefore($printSection, document.body.firstChild);
window.print();
// Clean up print section for future use
var oldElem = document.getElementById("printSection");
if (oldElem != null) { oldElem.parentNode.removeChild(oldElem); }
//oldElem.remove() not supported by IE
return true;
}
I had no need for appending elements, so I removed that aspect and changed the function to specifically print a div.
And the modal template. This prints the modal header & body and excludes the footer, where the buttons were located.
<div class="modal-content">
<div id="print-me"> <!-- This is the div that is cloned and printed -->
<div class="modal-header">
<!-- HEADER CONTENT -->
</div>
<div class="modal-body">
<!-- BODY CONTENT -->
</div>
</div>
<div class="modal-footer">
<!-- This is where I specify the div to print -->
<button type="button" class="btn btn-default" onclick="printDiv('print-me')">Print</button>
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
I hope that helps someone!
you can get the nodejs configuration from http://nodejs.org/
The important thing you need to keep in your mind is about its configuration in file app.js which consists of port number host and other settings these are settings working for me
backendSettings = { "scheme":"https / http ", "host":"Your website url", "port":49165, //port number 'sslKeyPath': 'Path for key', 'sslCertPath': 'path for SSL certificate', 'sslCAPath': '', "resource":"/socket.io", "baseAuthPath": '/nodejs/', "publishUrl":"publish", "serviceKey":"", "backend":{ "port":443, "scheme": 'https / http', //whatever is your website scheme "host":"host name", "messagePath":"/nodejs/message/"}, "clientsCanWriteToChannels":false, "clientsCanWriteToClients":false, "extensions":"", "debug":false, "addUserToChannelUrl": 'user/channel/add/:channel/:uid', "publishMessageToContentChannelUrl": 'content/token/message', "transports":["websocket", "flashsocket", "htmlfile", "xhr-polling", "jsonp-polling"], "jsMinification":true, "jsEtag":true, "logLevel":1};
In this if you are getting "Error: listen EADDRINUSE" then please change the port number i.e, here I am using "49165" so you can use other port such as 49170 or some other port.
For this you can refer to the following article
http://www.a2hosting.com/kb/installable-applications/manual-installations/installing-node-js-on-shared-hosting-accounts
Here is one-liner to verify certificate chain:
openssl verify -verbose -x509_strict -CAfile ca.pem cert_chain.pem
This doesn't require to install CA anywhere.
See How does an SSL certificate chain bundle work? for details.
The iterator of _.each
is called with 3 parameters (element, index, list)
. So yes, for _.each
you cab get the index.
You can do the same in sortBy
Set your PRIMARY KEY as AUTO_INCREMENT.
@classmethod
means: when this method is called, we pass the class as the first argument instead of the instance of that class (as we normally do with methods). This means you can use the class and its properties inside that method rather than a particular instance.
@staticmethod
means: when this method is called, we don't pass an instance of the class to it (as we normally do with methods). This means you can put a function inside a class but you can't access the instance of that class (this is useful when your method does not use the instance).
I assume that you haven't set the TableName
property of the DataTable, for example via constructor:
var tbl = new DataTable("dtImage");
If you don't provide a name, it will be automatically created with "Table1"
, the next table will get "Table2"
and so on.
Then the solution would be to provide the TableName
and then check with Contains(nameOfTable)
.
To clarify it: You'll get an ArgumentException
if that DataTable already belongs to the DataSet (the same reference). You'll get a DuplicateNameException
if there's already a DataTable in the DataSet with the same name(not case-sensitive).
To retrieve your image from byte to base64 string....
Model property:
public byte[] NomineePhoto { get; set; }
public string NomineePhoneInBase64Str
{
get {
if (NomineePhoto == null)
return "";
return $"data:image/png;base64,{Convert.ToBase64String(NomineePhoto)}";
}
}
IN view:
<img style="height:50px;width:50px" src="@item.NomineePhoneInBase64Str" />
You can assign a class
to your ASP.NET
Button and then apply the desired style to it.
<asp:Button class="mybtn" Text="Button" runat="server"></asp:Button>
CSS:
.mybtn
{
border:1px solid Red;
//some more styles
}
Selects are slow and unnescsaary. The following code will be far faster:
Sub CopyRowsAcross()
Dim i As Integer
Dim ws1 As Worksheet: Set ws1 = ThisWorkbook.Sheets("Sheet1")
Dim ws2 As Worksheet: Set ws2 = ThisWorkbook.Sheets("Sheet2")
For i = 2 To ws1.Range("B65536").End(xlUp).Row
If ws1.Cells(i, 2) = "Your Critera" Then ws1.Rows(i).Copy ws2.Rows(ws2.Cells(ws2.Rows.Count, 2).End(xlUp).Row + 1)
Next i
End Sub
I Think I can improve on this answer. Try this:
The parameter 'Pranks' is a CSV. ie. '1,2,3,4.....etc'
CREATE PROCEDURE AddRanks(
IN Pranks TEXT
)
BEGIN
DECLARE VCounter INTEGER;
DECLARE VStringToAdd VARCHAR(50);
SET VCounter = 0;
START TRANSACTION;
REPEAT
SET VStringToAdd = (SELECT TRIM(SUBSTRING_INDEX(Pranks, ',', 1)));
SET Pranks = (SELECT RIGHT(Pranks, TRIM(LENGTH(Pranks) - LENGTH(SUBSTRING_INDEX(Pranks, ',', 1))-1)));
INSERT INTO tbl_rank_names(rank)
VALUES(VStringToAdd);
SET VCounter = VCounter + 1;
UNTIL (Pranks = '')
END REPEAT;
SELECT VCounter AS 'Records added';
COMMIT;
END;
This method makes the searched string of CSV values progressively shorter with each iteration of the loop, which I believe would be better for optimization.
It's really late now but I made a quick script which works for Windows, Mac and Linux, simply by using each command line:
import os, platform
def close():
if platform.system() == "Windows":
print("Press any key to exit . . .")
os.system("pause>nul")
exit()
elif platform.system() == "Linux":
os.system("read -n1 -r -p \"Press any key to exit . . .\" key")
exit()
elif platform.system() == "Darwin":
print("Press any key to exit . . .")
os.system("read -n 1 -s -p \"\"")
exit()
else:
exit()
It uses only inbuilt functions, and should work for all three (although I've only tested Windows and Linux...).
You can do that I believe. It needs root permission. If you want to know where your apk files are stored, open a emulator and then go to
DDMS>File Explorer-> you can see a directory by name "data" -> Click on it and you will see a "app" folder.
Your apks are stored there. In fact just copying a apk directly to the folder works for me with emulators.
Just add ?author=<emailaddress>
or ?author=<githubUserName>

Here's how you can debug CORS requests using curl.
Sending a regular CORS request using cUrl:
curl -H "Origin: http://example.com" --verbose \
https://www.googleapis.com/discovery/v1/apis?fields=
The -H "Origin: http://example.com"
flag is the third party domain making the request. Substitute in whatever your domain is.
The --verbose
flag prints out the entire response so you can see the request and response headers.
The url I'm using above is a sample request to a Google API that supports CORS, but you can substitute in whatever url you are testing.
The response should include the Access-Control-Allow-Origin
header.
Sending a preflight request using cUrl:
curl -H "Origin: http://example.com" \
-H "Access-Control-Request-Method: POST" \
-H "Access-Control-Request-Headers: X-Requested-With" \
-X OPTIONS --verbose \
https://www.googleapis.com/discovery/v1/apis?fields=
This looks similar to the regular CORS request with a few additions:
The -H
flags send additional preflight request headers to the server
The -X OPTIONS
flag indicates that this is an HTTP OPTIONS request.
If the preflight request is successful, the response should include the Access-Control-Allow-Origin
, Access-Control-Allow-Methods
, and Access-Control-Allow-Headers
response headers. If the preflight request was not successful, these headers shouldn't appear, or the HTTP response won't be 200.
You can also specify additional headers, such as User-Agent
, by using the -H
flag.
There is one event which is default associate with any webcontrol. For example, in case of Button click event, in case of Check box CheckChangedEvent is there. So in case of AutoPostBack true these events are called by default and event handle at server side.
Added another case to Michal Górny's answer:
Note that relative imports are based on the name of the current module. Since the name of the main module is always "__main__
", modules intended for use as the main module of a Python application must always use absolute imports.
In your .htaccess you can add:
PHP 5.x
<IfModule mod_php5.c>
php_value memory_limit 64M
</IfModule>
PHP 7.x
<IfModule mod_php7.c>
php_value memory_limit 64M
</IfModule>
If page breaks again, then you are using PHP as mod_php in apache, but error is due to something else.
If page does not break, then you are using PHP as CGI module and therefore cannot use php values - in the link I've provided might be solution but I'm not sure you will be able to apply it.

Download the GLUT library. At first step Copy the glut32.dll and paste it in C:\Windows\System32 folder.Second step copy glut.h file and paste it in C:\Program Files\Microsoft Visual Studio\VC\include folder and third step copy glut32.lib and paste it in c:\Program Files\Microsoft Visual Studio\VC\lib folder. Now you can create visual c++ console application project and include glut.h header file then you can write code for GLUT project. If you are using 64 bit windows machine then path and glut library may be different but process is similar.

@DSM's answer is perfectly fine in almost any normal scenario. But if you're the type of programmer who wants to go a little deeper than the surface level, you might be interested to know that it is a little faster to call numpy functions on the underlying .to_numpy()
(or .values
for <0.24) array instead of directly calling the (cythonized) functions defined on the DataFrame/Series objects.
For example, you can use ndarray.max()
along the first axis.
# Data borrowed from @DSM's post.
df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
df
A B
0 1 -2
1 2 8
2 3 1
df['C'] = df[['A', 'B']].values.max(1)
# Or, assuming "A" and "B" are the only columns,
# df['C'] = df.values.max(1)
df
A B C
0 1 -2 1
1 2 8 8
2 3 1 3
If your data has NaN
s, you will need numpy.nanmax
:
df['C'] = np.nanmax(df.values, axis=1)
df
A B C
0 1 -2 1
1 2 8 8
2 3 1 3
You can also use numpy.maximum.reduce
. numpy.maximum
is a ufunc (Universal Function), and every ufunc has a reduce
:
df['C'] = np.maximum.reduce(df['A', 'B']].values, axis=1)
# df['C'] = np.maximum.reduce(df[['A', 'B']], axis=1)
# df['C'] = np.maximum.reduce(df, axis=1)
df
A B C
0 1 -2 1
1 2 8 8
2 3 1 3
np.maximum.reduce
and np.max
appear to be more or less the same (for most normal sized DataFrames)—and happen to be a shade faster than DataFrame.max
. I imagine this difference roughly remains constant, and is due to internal overhead (indexing alignment, handling NaNs, etc).
The graph was generated using perfplot. Benchmarking code, for reference:
import pandas as pd
import perfplot
np.random.seed(0)
df_ = pd.DataFrame(np.random.randn(5, 1000))
perfplot.show(
setup=lambda n: pd.concat([df_] * n, ignore_index=True),
kernels=[
lambda df: df.assign(new=df.max(axis=1)),
lambda df: df.assign(new=df.values.max(1)),
lambda df: df.assign(new=np.nanmax(df.values, axis=1)),
lambda df: df.assign(new=np.maximum.reduce(df.values, axis=1)),
],
labels=['df.max', 'np.max', 'np.maximum.reduce', 'np.nanmax'],

We can use the core java stuff alone to read the CVS file column by column. Here is the sample code I have wrote for my requirement. I believe that it will help for some one.
BufferedReader br = new BufferedReader(new FileReader(csvFile));
String line = EMPTY;
int lineNumber = 0;
int productURIIndex = -1;
int marketURIIndex = -1;
int ingredientURIIndex = -1;
int companyURIIndex = -1;
// read comma separated file line by line
while ((line = br.readLine()) != null) {
lineNumber++;
// use comma as line separator
String[] splitStr = line.split(COMMA);
int splittedStringLen = splitStr.length;
// get the product title and uri column index by reading csv header
// line
if (lineNumber == 1) {
for (int i = 0; i < splittedStringLen; i++) {
if (splitStr[i].equals(PRODUCTURI_TITLE)) {
productURIIndex = i;
System.out.println("product_uri index:" + productURIIndex);
}
if (splitStr[i].equals(MARKETURI_TITLE)) {
marketURIIndex = i;
System.out.println("marketURIIndex:" + marketURIIndex);
}
if (splitStr[i].equals(COMPANYURI_TITLE)) {
companyURIIndex = i;
System.out.println("companyURIIndex:" + companyURIIndex);
}
if (splitStr[i].equals(INGREDIENTURI_TITLE)) {
ingredientURIIndex = i;
System.out.println("ingredientURIIndex:" + ingredientURIIndex);
}
}
} else {
if (splitStr != null) {
String conditionString = EMPTY;
// avoiding arrayindexoutboundexception when the line
// contains only ,,,,,,,,,,,,,
for (String s : splitStr) {
conditionString = s;
}
if (!conditionString.equals(EMPTY)) {
if (productURIIndex != -1) {
productCVSUriList.add(splitStr[productURIIndex]);
}
if (companyURIIndex != -1) {
companyCVSUriList.add(splitStr[companyURIIndex]);
}
if (marketURIIndex != -1) {
marketCVSUriList.add(splitStr[marketURIIndex]);
}
if (ingredientURIIndex != -1) {
ingredientCVSUriList.add(splitStr[ingredientURIIndex]);
}
}
}
}
If you use Homebrew on OS X, then you have a simpler solution:
$ brew install go --with-cc-common # Linux, Darwin, and Windows
or..
$ brew install go --with-cc-all # All the cross-compilers
Use reinstall
if you already have go
installed.
I stumbled on this question while trying to do the same thing (I think). Here is how I did it:
df['index_col'] = df.index
You can then sort on the new index column, if you like.
generally, I make by simple way, whatever, I create a restAPI endpoint for example "localhost/api/method/:lastIdObtained/:countDateToReturn" with theses parameters, you can do it a simple request. in the service, eg. .net
jsonData function(lastIdObtained,countDatetoReturn){
'... write your code as you wish..'
and into select query make a filter
select top countDatetoreturn tt.id,tt.desc
from tbANyThing tt
where id > lastIdObtained
order by id
}
In Ionic, when I scroll from bottom to top, I pass the zero value, when I get the answer, I set the value of the last id obtained, and when I slide from top to bottom, I pass the last registration id I got
Mine DID execute commands in order. Here's my version of what I was using it for:
START cmd.exe /k "U: & cd U:\Design_stuff\new_lcso_website_2017 & python -m http.server"
I needed to
If those commands are out of order, it would not display the correct files. I initially forgot to change to U:
and, running the batch file on my Desktop, it created a web page in my browser at http://localhost:8000 showing me the contents of my Desktop instead of the folder I wanted.
You can fetch the parent class by adding the line below. If you had an id, it would be easier with getElementById
. Nonetheless,
var parentNode = document.getElementsByClassName("progress__container")[0];
Then you can use querySelectorAll
on the parent <div>
to fetch all matching div
s with class .progress__marker
var progressNodes = progressContainer.querySelectorAll('.progress__marker');
querySelectorAll
will fetch every div
with the class of progress__marker
AssertJ provides an excellent feature in extracting()
: you can pass Function
s to extract fields. It provides a check at compile time.
You could also assert the size first easily.
It would give :
import static org.assertj.core.api.Assertions;
Assertions.assertThat(myClass.getMyItems())
.hasSize(2)
.extracting(MyItem::getName)
.containsExactlyInAnyOrder("foo", "bar");
containsExactlyInAnyOrder()
asserts that the list contains only these values whatever the order.
To assert that the list contains these values whatever the order but may also contain other values use contains()
:
.contains("foo", "bar");
As a side note : to assert multiple fields from elements of a List
, with AssertJ we do that by wrapping expected values for each element into a tuple()
function :
import static org.assertj.core.api.Assertions;
import static org.assertj.core.groups.Tuple;
Assertions.assertThat(myClass.getMyItems())
.hasSize(2)
.extracting(MyItem::getName, MyItem::getOtherValue)
.containsExactlyInAnyOrder(
tuple("foo", "OtherValueFoo"),
tuple("bar", "OtherValueBar")
);
You are doing everything right, except passing your bundle path to asset()
function.
According to documentation - in your example this should look like below:
{{ asset('bundles/webshome/css/main.css') }}
Tip: you also can call assets:install with --symlink
key, so it will create symlinks in web folder. This is extremely useful when you often apply js
or css
changes (in this way your changes, applied to src/YouBundle/Resources/public
will be immediately reflected in web
folder without need to call assets:install
again):
app/console assets:install web --symlink
Also, if you wish to add some assets in your child template, you could call parent()
method for the Twig block. In your case it would be like this:
{% block stylesheets %}
{{ parent() }}
<link href="{{ asset('bundles/webshome/css/main.css') }}" rel="stylesheet">
{% endblock %}
<input type='text' minlength=3 /><br />
if browser supports html5,
it will automatical be validate attributes(minlength) in tag

To diagnose this issue, place the line of code causing the TargetInvocationException inside the try block.
To troubleshoot this type of error, get the inner exception. It could be due to a number of different issues.
try
{
// code causing TargetInvocationException
}
catch (Exception e)
{
if (e.InnerException != null)
{
string err = e.InnerException.Message;
}
}
On Mac:
?+CTRL+g
However, you can reset any key any way you'd like using "Customize your Sublime Text 2 configuration for awesome coding." for Mac.
On Windows/Linux:
Alt+F3
If anyone has how-tos or articles on this, I'd be more than happy to update.
All the answers here use the jQuery library.
But the vanilla javascript is very straightforward.
If you want to run a script only if the element with an id
of #dataTable
also has a data-timer
attribute, then the steps are as follows:
// Locate the element
const myElement = document.getElementById('dataTable');
// Run conditional code
if (myElement.dataset.hasOwnProperty('timer')) {

The ServletContext#getRealPath()
is intented to convert a web content path (the path in the expanded WAR folder structure on the server's disk file system) to an absolute disk file system path.
The "/"
represents the web content root. I.e. it represents the web
folder as in the below project structure:
YourWebProject
|-- src
| :
|
|-- web
| |-- META-INF
| | `-- MANIFEST.MF
| |-- WEB-INF
| | `-- web.xml
| |-- index.jsp
| `-- login.jsp
:
So, passing the "/"
to getRealPath()
would return you the absolute disk file system path of the /web
folder of the expanded WAR file of the project. Something like /path/to/server/work/folder/some.war/
which you should be able to further use in File
or FileInputStream
.
Note that most starters don't seem to see/realize that you can actually pass the whole web content path to it and that they often use
String absolutePathToIndexJSP = servletContext.getRealPath("/") + "index.jsp"; // Wrong!
or even
String absolutePathToIndexJSP = servletContext.getRealPath("") + "index.jsp"; // Wronger!
instead of
String absolutePathToIndexJSP = servletContext.getRealPath("/index.jsp"); // Right!
Also note that even though you can write new files into it using FileOutputStream
, all changes (e.g. new files or edited files) will get lost whenever the WAR is redeployed; with the simple reason that all those changes are not contained in the original WAR file. So all starters who are attempting to save uploaded files in there are doing it wrong.
Moreover, getRealPath()
will always return null
or a completely unexpected path when the server isn't configured to expand the WAR file into the disk file system, but instead into e.g. memory as a virtual file system.
getRealPath()
is unportable; you'd better never use itUse getRealPath()
carefully. There are actually no sensible real world use cases for it. Based on my 20 years of Java EE experience, there has always been another way which is much better and more portable than getRealPath()
.
If all you actually need is to get an InputStream
of the web resource, better use ServletContext#getResourceAsStream()
instead, this will work regardless of the way how the WAR is expanded. So, if you for example want an InputStream
of index.jsp
, then do not do:
InputStream input = new FileInputStream(servletContext.getRealPath("/index.jsp")); // Wrong!
But instead do:
InputStream input = servletContext.getResourceAsStream("/index.jsp"); // Right!
Or if you intend to obtain a list of all available web resource paths, use ServletContext#getResourcePaths()
instead.
Set<String> resourcePaths = servletContext.getResourcePaths("/");
You can obtain an individual resource as URL
via ServletContext#getResource()
. This will return null
when the resource does not exist.
URL resource = servletContext.getResource(path);
Or if you intend to save an uploaded file, or create a temporary file, then see the below "See also" links.
I don't think you can save it without it appearing, but just for saving in multiple formats use the print command. See the answer posted here: Save an imagesc output in Matlab
I think all explanations above are a bit too technical for the people who are new to Object Oriented Programming (OOP). Years ago, it took me a while to wrap my head around this (as Jr Java Developer) and I really did no understand why we use a parent class or an interface to hide the actual class we are actually calling under the covers.
The immediate reason why is to hide complexity, so that the caller does not need to change often (be hacked and jacked in laymen's terms). This makes a lot of sense, especially if you goals is to avoid creating bugs. And the more you modify code, the more likely it is that you will have some of them creep up on you. On the other hand, if you just extend code, it is way less likely that you will have bugs because you concentrate on one thing at a time and your old code does not change or changes just a bit. Imagine that you have simple application that allows the employees in the medical profession to create profiles. For simplicity, let's assume that we have only GeneralPractitioners, Surgeons, and Nurses (in reality there are many more specific professions, of course). For each profession, you want to store some general information and some specific to that professional alone. For example, a Surgeon may have general fields like firstName, lastName, yearsOfExperience as general fields but also specific fields, e.g. specializations stored in an list instance variable, like List with contents simiar to "Bone Surgery", "Eye Surgery", etc. A Nurse would not have any of that but may have list procedures they are familiar with, GeneralPractioners would have their own specifics. As a result, how you save a profile of a specifics. However, you don't want your ProfileManager class to know about these differences, as they will inevitably change and increase over time as your application expands its functionality to cover more medical professions, e.g. Physio Therapist, Cardiologist, Oncologist, etc. All you want your ProfileManger to do is just say save(), no matter whose profile it is saving. Thus, it is common practice to hide this behind and Interface, and Abstract Class, or a Parent Class (if you plan to allow creating a general medical employee). In this case, let's choose a Parent class and call it MedicalEmployee. Under the covers, it can reference any of the above specific classes that extend it. When the ProfileManager calls myMedicalEmployee.save() the save() method will be polymorphically (many-structurally) be resolved to the correct class type that was used to create the profile originally, for example Nurse and call the save() method in that class.
In many cases, you don't really know what implementation you will need at runtime. From the example above, you have no idea if a GeneralPractitioner, a Surgeon, or a Nurse would create a profile. Yet, you know that you need to save that profile once completed, no matter what. MedicalEmployee.profile() does exactly that. It is replicated (overridden) by each specific type of MedicalEmployee - GeneralPractitioner, Surgeon, Nurse,
The result of (1) and (2) above is that you now can add new medical professions, implement save() in each new class, thereby overriding the save() method in MedicalEmployee, and you don't have to modify ProfileManager at all.

you can use html entity as •
Quirks Mode: images and display: none
When image has
display: none
or is inside an element withdisplay:none
, the browser may opt not to download the image until thedisplay
is set to another value.Only Opera downloads the image when you switch the
display
toblock
. All other browsers download it immediately.
One special case for this is if you have used a construction like the following in your ~/.muttrc:
# Reset From email to default
send-hook . "my_hdr From: Real Name <[email protected]>"
This send-hook will override either of these:
mutt -e "set [email protected]"
mutt -e "my_hdr From: Other Name <[email protected]>"
Your emails will still go out with the header:
From: Real Name <[email protected]>
In this case, the only command line solution I've found is actually overriding the send-hook itself:
mutt -e "send-hook . \"my_hdr From: Other Name <[email protected]>\""
update INC.PROV_CSP_DEMO_ADDR_TEMP pd
set pd.practice_name = (
select PRSQ_COMMENT FROM INC.CMC_PRSQ_SITE_QA PRSQ
WHERE PRSQ.PRSQ_MCTR_ITEM = 'PRNM'
AND PRSQ.PRAD_ID = pd.provider_id
AND PRSQ.PRAD_TYPE = pd.prov_addr_type
AND ROWNUM = 1
)
The only selector I see is a[id$="name"]
(all links with id finishing by "name") but it's not as restrictive as it should.
string hex = "#FFFFFF";
Color _color = System.Drawing.ColorTranslator.FromHtml(hex);
Note: the hash is important!
First convert all your objects into valid Strings
HashMap<String, String> params = new HashMap<>();
params.put("arg1", "<b>some text</b>");
params.put("arg2", someObject.toString());
Then insert the entire map into a org.json.JSONObject
JSONObject postData = new JSONObject(params);
Now you can get the JSON by simply calling the object's toString
postData.toString()
//{"arg1":"<b>some text<\/b>" "arg2":"object output"}
Create a new JSONObject
JSONObject o = new JSONObject(postData.toString());
Or as a byte array for sending over HTTP
postData.toString().getBytes("UTF-8");
Try
System.exit(0);
this should terminate thread main and end the main program
I got the same problem (with Plesk 12 installed). However, when i switched from execute PHP as FastCGI to Apache Module the website worked.
Checked my suexec log:
$ cd /var/log/apache2/
$ less suexec.log
When you find something like this:

try this commands
$ chown root:root /var/www/cgi-bin/cgi_wrapper
$ chmod 755 /var/www/cgi-bin/cgi_wrapper
$ shutdown -r now

I hope it can help you.
If your filename contains a dot (other than the one of the extension) then use this:
