There is a firewall blocking the connection or the process that is hosting the service is not listening on that port. Or it is listening on a different port.
Install tether via npm like below
npm install tether --save-dev
then add tether to your html above bootstrap like below
<script src="node_modules/tether/dist/js/tether.min.js"></script>
<script src="jspm_packages/github/twbs/[email protected]/js/bootstrap.js"></script>
Probably the file is not in the path specified. '../../../' will move 3 step up to the directory in which the page is located and look for the js file in a folder named JS.
Also the language attribute is Deprecated.
See Scripts:
18.2.1 The SCRIPT element
Deprecated. This attribute specifies the scripting language of the contents of this element. Its value is an identifier for the language, but since these identifiers are not standard, this attribute has been deprecated in favor of type.

Try changing

If
(1) you have a _Layout.cshtml view like this
<html>
<body>
@RenderBody()
</body>
<script type="text/javascript" src="~/lib/layout.js"></script>
@RenderSection("scripts", required: false)
</html>
(2) you have Contacts.cshtml
@section Scripts{
<script type="text/javascript" src="~/lib/contacts.js"></script>
}
<div class="row">
<div class="col-md-6 col-md-offset-3">
<h2> Contacts</h2>
</div>
</div>
(3) you have About.cshtml
<div class="row">
<div class="col-md-6 col-md-offset-3">
<h2> Contacts</h2>
</div>
</div>
On you layout page, if required is set to false "@RenderSection("scripts", required: false)", When page renders and user is on about page, the contacts.js doesn't render.
<html>
<body><div>About<div>
</body>
<script type="text/javascript" src="~/lib/layout.js"></script>
</html>
if required is set to true "@RenderSection("scripts", required: true)", When page renders and user is on ABOUT page, the contacts.js STILL gets rendered.
<html>
<body><div>About<div>

IN SHORT, when set to true, whether you need it or not on other pages, it will get rendered anyhow. If set to false, it will render only when the child page is rendered.
None of the above answers worked for me using git version 1.8.3.msysgit.0 and TortoiseGit 1.8.4.0.
In my particular situation, I have to connect to the remote git repo over HTTPS, using a full blown e-mail address as username.
In this situation, wincred
did not appear to work.
Using the email address as a part of the repo URL also did not work, as the software seems to be confused by the double appearance of the '@' character in the URL.
I did manage to overcome the problem using winstore
. Here is what I did:
winstore
from http://gitcredentialstore.codeplex.com/git-credential-winstore.exe
to install it.This will copy the git-credential-winstore.exe
to a local directory and add two lines to your global .gitconfig
. You can verify this by examining your global .gitconfig
. This is easiest done via right mouse button on a folder, "TortoiseGit > Settings > Git > Edit global .gitconfig". The file should contain two lines like:
[credential]
helper = !'C:\\Users\\yourlogin\\AppData\\Roaming\\GitCredStore\\git-credential-winstore.exe'
You are now ready to go:
winstore
works. Enter the correct authentication and the pull should succeed.Done!
Enjoy your interactions with the remote repo while winstore
takes care of the authentication.
(*) Alternatively, if you don't like the blank selection in the TortoiseGit Credential settings helper pull down menu, you can use the "Advanced" option:
Enter the Helper path as below. Note: a regular Windows path notation (e.g. "C:\Users...") will not work here, you have to replicate the exact line that installing winstore
created in the global .gitconf
without the "helper =" bit.
!'C:\\Users\\yourlogin\\AppData\\Roaming\\GitCredStore\\git-credential-winstore.exe'
Click the "Add New/Save" button
I'm taking a cue from the comments in @Dhara's answer, it sounds like you want to set a list of new_tick_locations
by a function from the old x-axis to the new x-axis. The tick_function
below takes in a numpy array of points, maps them to a new value and formats them:
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twiny()
X = np.linspace(0,1,1000)
Y = np.cos(X*20)
ax1.plot(X,Y)
ax1.set_xlabel(r"Original x-axis: $X$")
new_tick_locations = np.array([.2, .5, .9])
def tick_function(X):
V = 1/(1+X)
return ["%.3f" % z for z in V]
ax2.set_xlim(ax1.get_xlim())
ax2.set_xticks(new_tick_locations)
ax2.set_xticklabels(tick_function(new_tick_locations))
ax2.set_xlabel(r"Modified x-axis: $1/(1+X)$")
plt.show()
Use the queryset object update
method:
MyModel.objects.filter(pk=some_value).update(field1='some value')
UPDATE your_table
SET your_field = REPLACE(your_field, 'articles/updates/', 'articles/news/')
WHERE your_field LIKE '%articles/updates/%'
Now rows that were like
http://www.example.com/articles/updates/43
will be
http://www.example.com/articles/news/43
If you are returning a complex json object you need to modify you success function of your auto-complete as follows.
$.ajax({
url: "/Employees/SearchEmployees",
dataType: "json",
data: {
searchText: request.term
},
success: function (data) {
response($.map(data.employees, function (item) {
return {
label: item.name,
value: item.id
};
}));
}
});
Go to the Servers project in eclipse, under your runtime server configuration(in my case Tomcat v7.0 Server at localhost-config) go to server.xml file then search for <context> tag, normally you will find more than one context tag, delete them and run your application in the appropriate server that will work now.
in my case i have found duplicate Context tag :
<Context docBase="my-project" path="/my-project" reloadable="true" source="org.eclipse.jst.jee.server:my-project"/><Context docBase="my-project" path="/smartphone-selfcare" reloadable="true" source="org.eclipse.jst.jee.server:my-project"/></Host>
I think this picture can also be useful, it helps me as a reference when I want to quickly remember the differences between isolation levels (thanks to kudvenkat on youtube)
I think there is no "right" way to do this. You have to choose the best fit solution for your use case.
In my iPad App I have a UIViewController
that is presented modal as UIModalPresentationFormSheet
and consists of an UITableView
. This table contains two UITextFields
per cell.
Just calling scrollToRowAtIndexPath:atScrollPosition:animated:
in the textFieldDidBeginEditing:
method doesn't work for me. Therefore I have created a tableFooterView
:
- (void)viewDidLoad
{
[super viewDidLoad];
m_footerView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, m_tableView.frame.size.width, 300.0f)];
[m_footerView setBackgroundColor:[UIColor clearColor]];
[m_tableView setTableFooterView:m_footerView];
[m_footerView release];
}
The idea is that keyboard hides the tableFooterView
and not the UITextFields
. So the tableFooterView
must be high enough. After that you can use scrollToRowAtIndexPath:atScrollPosition:animated:
in the textFieldDidBeginEditing:
method.
I think it's also possible to show and hide the tableFooterView
dynamically by adding the observers for the keyboard notifications but I haven't tried it yet:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillHide:)
name:UIKeyboardWillHideNotification
object:nil];
}
- (void)keyboardWillShow:(NSNotification *)notification
{
[m_tableView setTableFooterView:m_footerView];
}
- (void)keyboardWillHide:(NSNotification *)notification
{
[m_tableView setTableFooterView:nil];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}
My simple answer is:
#include <iostream>
using namespace std;
int main()
{
int data[]{ 1, 2, 7 };
for (int i = sizeof(data) / sizeof(data[0])-1; i >= 0; i--) {
cout << data[i];
}
return 0;
}
You've already got it: A if test else B
is a valid Python expression. The only problem with your dict comprehension as shown is that the place for an expression in a dict comprehension must have two expressions, separated by a colon:
{ (some_key if condition else default_key):(something_if_true if condition
else something_if_false) for key, value in dict_.items() }
The final if
clause acts as a filter, which is different from having the conditional expression.
Here is the program in java which is O(N^2)

if (sumInStack == TARGET_SUM) {

Generally Server JDK version will be lower than the deployed application (built with higher jdk version)
$.post('someUri', { },
function(data){ doSomeStuff })
.fail(function(error) { alert(error.responseJSON) });
To fix this,
you’ll need to reset the permissions back to default:
sudo chmod 600 ~/.ssh/id_rsa
sudo chmod 600 ~/.ssh/id_rsa.pub
If you are getting another error:
This means that the permissions on that file are also set incorrectly, and can be adjusted with this:
sudo chmod 644 ~/.ssh/known_hosts
Finally, you may need to adjust the directory permissions as well:
sudo chmod 755 ~/.ssh
This should get you back up and running.
I know, that's the "answer" nobody wants. But if something's worth doing, it's worth doing right, right?
This seeming like a good idea probably stems from a fairly wide misconception that shell commands such as curl
are anything other than programs themselves.
So what you're asking is "how do I run this other program, from within my program, just to make a measly little web request?". That's crazy, there's got to be a better way right?
Uxio's answer works, sure. But it hardly looks very Pythonic, does it? That's a lot of work just for one little request. Python's supposed to be about flying! Anyone writing that is probably wishing they just call
'd curl
!
it works, but is there a better way?
Things shouldn’t be this way. Not in Python.
Let's GET this page:
import requests
res = requests.get('https://stackoverflow.com/questions/26000336')
That's it, really! You then have the raw res.text
, or res.json()
output, the res.headers
, etc.
You can see the docs (linked above) for details of setting all the options, since I imagine OP has moved on by now, and you - the reader now - likely need different ones.
But, for example, it's as simple as:
url = 'http://example.tld'
payload = { 'key' : 'val' }
headers = {}
res = requests.post(url, data=payload, headers=headers)
You can even use a nice Python dict to supply the query string in a GET request with params={}
.
Simple and elegant. Keep calm, and fly on.
The comparison needs to be evaluated fully inside EL ${ ... }
, not outside.
<c:if test="${values.type eq 'object'}">
As to the docs, those ${}
things are not JSTL, but EL (Expression Language) which is a whole subject at its own. JSTL (as every other JSP taglib) is just utilizing it. You can find some more EL examples here.
<c:if test="#{bean.booleanValue}" />
<c:if test="#{bean.intValue gt 10}" />
<c:if test="#{bean.objectValue eq null}" />
<c:if test="#{bean.stringValue ne 'someValue'}" />
<c:if test="#{not empty bean.collectionValue}" />
<c:if test="#{not bean.booleanValue and bean.intValue ne 0}" />
<c:if test="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />
By the way, unrelated to the concrete problem, if I guess your intent right, you could also just call Object#getClass()
and then Class#getSimpleName()
instead of adding a custom getter.
<c:forEach items="${list}" var="value">
<c:if test="${value['class'].simpleName eq 'Object'}">
<!-- code here -->
</c:if>
</c:forEeach>
If you want to do it with a Windows Store App, following by @Hans Kesting and @Jink answer:
string colorcode = "#FFEEDDCC";
int argb = Int32.Parse(colorcode.Replace("#", ""), NumberStyles.HexNumber);
tData.DefaultData = Color.FromArgb((byte)((argb & -16777216) >> 0x18),
(byte)((argb & 0xff0000) >> 0x10),
(byte)((argb & 0xff00) >> 8),
(byte)(argb & 0xff));
If you are using Spring MVC, then you need to declare default action servlet for static contents. Add the following entries in spring-action-servlet.xml. It worked for me.
NOTE: keep all the static contents outside WEB-INF.
<!-- Enable annotation-based controllers using @Controller annotations -->
<bean id="annotationUrlMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="order" value="0" />
</bean>
<bean id="controllerClassNameHandlerMapping" class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping">
<property name="order" value="1" />
</bean>
<bean id="annotationMethodHandlerAdapter" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
In my case, heredoc caused the issue. There is no problem with PHP version 7.3 up. Howerver, it error with PHP 7.0.33 if you use heredoc with space.
My example code
$rexpenditure = <<<Expenditure
<tr>
<td>$row->payment_referencenumber</td>
<td>$row->payment_requestdate</td>
<td>$row->payment_description</td>
<td>$row->payment_fundingsource</td>
<td>$row->payment_agencyulo</td>
<td>$row->payment_agencyproject</td>
<td>$$row->payment_disbustment</td>
<td>$row->payment_payeename</td>
<td>$row->payment_processpayment</td>
</tr>
Expenditure;
It will error if there is a space on PHP 7.0.33.
Instant.ofEpochSecond( 1_280_512_800L )
2010-07-30T18:00:00Z
The new java.time framework built into Java 8 and later is the successor to Joda-Time.
These new classes include a handy factory method to convert a count of whole seconds from epoch. You get an Instant
, a moment on the timeline in UTC with up to nanoseconds resolution.
Instant instant = Instant.ofEpochSecond( 1_280_512_800L );
instant.toString(): 2010-07-30T18:00:00Z
See that code run live at IdeOne.com.
Asia/Kabul
or Asia/Tehran
time zones ?You reported getting a time-of-day value of 22:30 instead of the 18:00 seen here. I suspect your PHP utility is implicitly applying a default time zone to adjust from UTC. My value here is UTC, signified by the Z
(short for Zulu
, means UTC). Any chance your machine OS or PHP is set to Asia/Kabul
or Asia/Tehran
time zones? I suppose so as you report IRST
in your output which apparently means Iran time. Currently in 2017 those are the only zones operating with a summer time that is four and a half hours ahead of UTC.
Specify a proper time zone name in the format of continent/region
, such as America/Montreal
, Africa/Casablanca
, or Pacific/Auckland
. Never use the 3-4 letter abbreviation such as EST
or IST
or IRST
as they are not true time zones, not standardized, and not even unique(!).
If you want to see your moment through the lens of a particular region's time zone, apply a ZoneId
to get a ZonedDateTime
. Still the same simultaneous moment, but seen as a different wall-clock time.
ZoneId z = ZoneId.of( "Asia/Tehran" ) ;
ZonedDateTime zdt = instant.atZone( z ); // Same moment, same point on timeline, but seen as different wall-clock time.
2010-07-30T22:30+04:30[Asia/Tehran]
You should stick with the new java.time classes. But you can convert to old if required.
java.util.Date date = java.util.Date.from( instant );
UPDATE: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.
FYI, the constructor for a Joda-Time DateTime is similar: Multiply by a thousand to produce a long
(not an int
!).
DateTime dateTime = new DateTime( ( 1_280_512_800L * 1000_L ), DateTimeZone.forID( "Europe/Paris" ) );
Best to avoid the notoriously troublesome java.util.Date and .Calendar classes. But if you must use a Date, you can convert from Joda-Time.
java.util.Date date = dateTime.toDate();
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
I understand that this is an old post but Windows is definitely not written in C++. There is lots of C++ in it but what we technical define as an operating system is not in C++. The Windows API, the Windows kernel (both of these are in essence what an operating system is) are written in C. Years ago I was given some leaked code for both Windows 2000 and Windows XP. The code was not nearly complete enough to compile the kernel or API but we were able to compile individual programs and services. For example, we were able to successfully compile Notepad.exe, mspaint.exe, and the spoolsv.exe service (print spooler). All written in C. I have not looked again but I am sure that leaked code still survives as torrent files out there that may still be available.
Add the following to the top of your file # coding=utf-8
If you go to the link in the error you can seen the reason why:
Defining the Encoding
Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=
I think that you only have to replace SHA1 function with SHA256 function with tatk code from link in Your post
As a side note, you can include the separators while splitting the string in Go. To do so, use strings.SplitAfter
as in the example below.
package main
import (
"fmt"
"strings"
)
func main() {
fmt.Printf("%q\n", strings.SplitAfter("z,o,r,r,o", ","))
}
I had the same problem and solved it by copying the MSVCR100.dll
file from sqldeveloper\jdk\jre\bin
to the sqldeveloper\sqldeveloper\bin
folder.
Credit goes to Erik Anderson from SQL Developer failed to start
Note that different versions of SQL Developer need different versions of MSVCR*.dll
. Various comments below have offered which versions worked for them.
In order to avoid duplicate code, I recommend you to define the color once, for both states:
a, a:visited{
color: /* some color */;
}
This, indeeed, will mantain your <a>
color (whatever this color is) even when the link has been visited.
Notice that, if the color of the element inside of the <a>
is being inherited (e.g. the color is set in the body
), you could do the following trick:
a, a:visited {
color: inherit;
}
Since you want to check whether textboxes contains any value or not your code should do the job. You should be more specific about the error you are having. You can also do:
if(textBox1.Text == string.Empty || textBox2.Text == string.Empty)
{
MessageBox.Show("You must enter a value into both boxes");
}
EDIT 2: based on @JonSkeet comments:
Usage of string.Compare is not required as per OP's original unedited post. String.Equals should do the job if one wants to compare strings, and StringComparison
may be used to ignore case for the comparison. string.Compare should be used for order comparison.
Originally the question contain this comparison,
string testString = "This is a test";
string testString2 = "This is not a test";
if (testString == testString2)
{
//do some stuff;
}
the if statement can be replaced with
if(testString.Equals(testString2))
or following to ignore case.
if(testString.Equals(testString2,StringComparison.InvariantCultureIgnoreCase))
I too was looking for this for Facebook reasons and none of the answers given so far worked as needed or are too complicated.
@Request.Url.GetLeftPart(UriPartial.Path)
Gets the full protocol, host and path "without" the querystring. Also includes the port if you are using something other than the default 80.
I would recommend the technique that MathieuK offers. In my case, I needed to try it with Chromium:
> Chromium.app/Contents/MacOS/Chromium --enable-remote-fonts
I realize this doesn't solve the OP's problem, but hopefully it saves someone else's time. :)
It seems that one of the most common reasons this happens is if you install a new version of PostgreSQL without stopping the service of an existing installation. This was a particular headache of mine, too. Before installing or upgrading, particularly on OS X and using the one click installer from Enterprise DB, make sure you check the status of the old installation before proceeding.
The HTML tabindex atribute is responsible for indicating if an element is reachable by keyboard navigation. When the user presses the Tab key the focus is shifted from one element to another. By using the tabindex atribute, the tab order flow is shifted.
I am answering this old question just because it still shows up in google queries and I think one optimal answer is missing. Try this code: use ::before or ::after
This is a select statement, so each branch of the case must return something. If you want to perform actions, just use an if.
You may be trying to find the view before onCreate()
which is incorrect.
public class MainActivity extends Activity {
ImageView mainImage = (ImageView) findViewById(R.id.imageViewMain); //incorrect
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
...
}
I think the reason it doesn't work has something to do with the fact that you have the right
position set, but not the left
.
If you manually set the left
to the current position, it seems to go:
Live example: http://jsfiddle.net/XqqtN/
var left = $('#coolDiv').offset().left; // Get the calculated left position
$("#coolDiv").css({left:left}) // Set the left to its calculated position
.animate({"left":"0px"}, "slow");
EDIT:
Appears as though Firefox behaves as expected because its calculated left
position is available as the correct value in pixels, whereas Webkit based browsers, and apparently IE, return a value of auto
for the left position.
Because auto
is not a starting position for an animation, the animation effectively runs from 0 to 0. Not very interesting to watch. :o)
Setting the left position manually before the animate as above fixes the issue.
If you don't like cluttering the landscape with variables, here's a nice version of the same thing that obviates the need for a variable:
$("#coolDiv").css('left', function(){ return $(this).offset().left; })
.animate({"left":"0px"}, "slow"); ?
The answer given by CMS works fine with the following modification for null checks as well
function checkNested(obj /*, level1, level2, ... levelN*/)
{
var args = Array.prototype.slice.call(arguments),
obj = args.shift();
for (var i = 0; i < args.length; i++)
{
if (obj == null || !obj.hasOwnProperty(args[i]) )
{
return false;
}
obj = obj[args[i]];
}
return true;
}
I know this is too late but for those who are coming here for the first time, I'd like to post a solution. I have a float value index
and a string imgfile
and I had the same problem as you. This is how I fixed the issue
index = 1.0
imgfile = 'data/2.jpg'
out = '%.1f,%s' % (index,imgfile)
print out
The output is
1.0,data/2.jpg
You may modify this formatting example as per your convenience.
Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.
Actually there is a more simple solution (only on Mac version). Just four steps:
UPDATE 21/11/2012 @ALL : I have updated the example so that it works better and takes into accounts remarks from Chris Jacob and FB Best practices, have a look of working example here
Hi So as promised here is my answer using only javascript :
The content of the BODY of the page :
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({
appId : 'YOUR APP ID',
status : true,
cookie : true,
xfbml : true
});
</script>
<div id="container_notlike">
YOU DONT LIKE
</div>
<div id="container_like">
YOU LIKE
</div>
The CSS :
body {
width:520px;
margin:0; padding:0; border:0;
font-family: verdana;
background:url(repeat.png) repeat;
margin-bottom:10px;
}
p, h1 {width:450px; margin-left:50px; color:#FFF;}
p {font-size:11px;}
#container_notlike, #container_like {
display:none
}
And finally the javascript :
$(document).ready(function(){
FB.login(function(response) {
if (response.session) {
var user_id = response.session.uid;
var page_id = "40796308305"; //coca cola
var fql_query = "SELECT uid FROM page_fan WHERE page_id = "+page_id+"and uid="+user_id;
var the_query = FB.Data.query(fql_query);
the_query.wait(function(rows) {
if (rows.length == 1 && rows[0].uid == user_id) {
$("#container_like").show();
//here you could also do some ajax and get the content for a "liker" instead of simply showing a hidden div in the page.
} else {
$("#container_notlike").show();
//and here you could get the content for a non liker in ajax...
}
});
} else {
// user is not logged in
}
});
});
So what what does it do ?
First it logins to FB (if you already have the USER ID, and you are sure your user is already logged in facebook, you can bypass the login stuff and replace response.session.uid
with YOUR_USER_ID (from your rails app for example)
After that it makes a FQL query on the page_fan
table, and the meaning is that if the user is a fan of the page, it returns the user id and otherwise it returns an empty array, after that and depending on the results its show a div or the other.
Also there is a working demo here : http://jsfiddle.net/dwarfy/X4bn6/
It's using the coca-cola page as an example, try it go and like/unlike the coca cola page and run it again ...

UPDATE 2
As stated by somebody, jQuery is required for the javascript version to work BUT you could easily remove it (it's only used for the document.ready and show/hide).
For the document.ready, you could wrap your code in a function and use body onload="your_function"
or something more complicated like here : Javascript - How to detect if document has loaded (IE 7/Firefox 3) so that we replace document ready.
And for the show and hide stuff you could use something like : document.getElementById("container_like").style.display = "none" or "block"
and for more reliable cross browser techniques see here : http://www.webmasterworld.com/forum91/441.htm
But jQuery is so easy :)
UPDATE
Relatively to the comment I posted here below here is some ruby code to decode the "signed_request" that facebook POST to your CANVAS URL when it fetches it for display inside facebook.
In your action controller :
decoded_request = Canvas.parse_signed_request(params[:signed_request])
And then its a matter of checking the decoded request and display one page or another .. (Not sure about this one, I'm not comfortable with ruby)
decoded_request['page']['liked']
And here is the related Canvas Class (from fbgraph ruby library) :
class Canvas
class << self
def parse_signed_request(secret_id,request)
encoded_sig, payload = request.split('.', 2)
sig = ""
urldecode64(encoded_sig).each_byte { |b|
sig << "%02x" % b
}
data = JSON.parse(urldecode64(payload))
if data['algorithm'].to_s.upcase != 'HMAC-SHA256'
raise "Bad signature algorithm: %s" % data['algorithm']
end
expected_sig = OpenSSL::HMAC.hexdigest('sha256', secret_id, payload)
if expected_sig != sig
raise "Bad signature"
end
data
end
private
def urldecode64(str)
encoded_str = str.gsub('-','+').gsub('_','/')
encoded_str += '=' while !(encoded_str.size % 4).zero?
Base64.decode64(encoded_str)
end
end
end

Here's what I do (please note that the JSON going to my server needs to be a dictionary with one value (another dictionary) for key = question..i.e. {:question => { dictionary } } ):
NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:@"StoreNickName"],
[[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:@"user_question"], nil];
NSArray *keys = [NSArray arrayWithObjects:@"nick_name", @"UDID", @"user_question", nil];
NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:@"question"];
NSString *jsonRequest = [jsonDict JSONRepresentation];
NSLog(@"jsonRequest is %@", jsonRequest);
NSURL *url = [NSURL URLWithString:@"https://xxxxxxx.com/questions"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSData *requestData = [jsonRequest dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: requestData];
NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if (connection) {
receivedData = [[NSMutableData data] retain];
}
The receivedData is then handled by:
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSDictionary *jsonDict = [jsonString JSONValue];
NSDictionary *question = [jsonDict objectForKey:@"question"];
This isn't 100% clear and will take some re-reading, but everything should be here to get you started. And from what I can tell, this is asynchronous. My UI is not locked up while these calls are made. Hope that helps.
If some desperate developer scrolls down here, I have another option to do it. Which also disables scrolling as far as I experimented with it. The idea is to use View element like this one in a RelativeLayout, under all your UI elements.
<View
android:id="@+id/shade"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/primaryShadow"
android:visibility="gone"/>
So it is set to be "gone" before some condition. And then you set it's visibility to VISIBLE when you want to disable your UI. Also you have to implement OnClickListener
for this View. This onClickListener
will catch click event and won't pass it to the underlying elements.
In GCC and Clang you can use the __attribute__((unused))
preprocessor directive to achieve your goal.
For example:
int foo (__attribute__((unused)) int bar) {
return 0;
}
leDbConnection connection =
new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Inventar.accdb");
DataSet1 DS = new DataSet1();
connection.Open();
OleDbDataAdapter DBAdapter = new OleDbDataAdapter(
@"SELECT tbl_Computer.*, tbl_Besitzer.*
FROM tbl_Computer
INNER JOIN tbl_Besitzer ON tbl_Computer.FK_Benutzer = tbl_Besitzer.ID
WHERE (((tbl_Besitzer.Vorname)='ma'));",
connection);
This page describes exactly how to do this.
https://developer.android.com/training/keyboard-input/style.html
Set the android:imeOptions then you just check the actionId in onEditorAction. So if you set imeOptions to 'actionDone' then you would check for 'actionId == EditorInfo.IME_ACTION_DONE' in onEditorAction. Also, make sure to set the android:inputType.
If using Material Design put code in TextInputEditText.
Here's the EditText from the example linked above:
<EditText
android:id="@+id/search"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/search_hint"
android:inputType="text"
android:imeOptions="actionSend" />
You can also set this programmatically using the setImeOptions(int) function. Here's the OnEditorActionListener from the example linked above:
EditText editText = (EditText) findViewById(R.id.search);
editText.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
boolean handled = false;
if (actionId == EditorInfo.IME_ACTION_SEND) {
sendMessage();
handled = true;
}
return handled;
}
});
N.B : IF YOU ARE USING PHPSTORM
I spent an hour trying to solve this problem, thinking that it was my php server problem, So i set 'always_populate_raw_post_data' to '-1' in php.ini and nothing worked.
Until i found out that using phpStorm built in server is what causing the problem as detailed in the answer here : Answer by LazyOne Here , So i thought about sharing it.
For me, the try_files
directive in the (currently most voted) answer https://stackoverflow.com/a/11957896/608359 led to rewrite cycles,
*173 rewrite or internal redirection cycle while internally redirecting
I had better luck with the index directive. Note that I used a forward slash before the name, which might or might not be what you want.
server {
listen 443 ssl;
server_name example.com;
root /home/dclo/example;
index /index.html;
error_page 404 /index.html;
# ... ssl configuration
}
In this case, I wanted all paths to lead to /index.html, including when returning a 404.
Another idea is to do myVar.split(',')[1];
For simple case, not using a regexp is a good idea...
Just document it here
on Windows you need to escape the \
character:
"e:\\directory\\-"
I found that ctrl + w to the window you want to close, then just do :q. This works for me.
Running the command prompt or Powershell ISE as an administrator fixed this for me.
because u have to have jquery set-up to enable the toggling functionality of the toggler button. So, all u have to do is to add bootstrap.bundle.js before bootstrap.css:
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>

I eventually installed an additional old version of Firefox (used for testing only) to resolve this, besides my regular (secure, up to date) latest Firefox installation.
This requires webdriver to know where it can find the Firefox binary, which can be set through the webdriver.firefox.bin
property.
What worked for me (mac, maven, /tmp/ff46
as installation folder) is:
mvn -Dwebdriver.firefox.bin=/tmp/ff46/Firefox.app/Contents/MacOS/firefox-bin verify
To install an old version of Firefox in a dedicated folder, create the folder, open Finder in that folder, download the Firefox dmg, and drag it to that Finder.
In the first iteration of your loop, you overwrite the value in array[1]
. You should go through the indicies in the reverse order.
The string you are returning is not valid JSON. The names in the objects needs to be quoted and the whole string needs to be put in { … }
to form an object. JSON also cannot contain something like new Date()
. JSON is just a small subset of JavaScript that has only strings, numbers, objects, arrays, true
, false
and null
.
See the JSON grammar for more information.
Just thought i'd share this with anyone who needs more clarity on how to achieve this:

Huffman encoding is a sensible option here. Gzip and friends do this, but the way they work is to build a Huffman tree for the input, send that, then send the data encoded with the tree. If the tree is large relative to the data, there may be no not saving in size.
However, it is possible to avoid sending a tree: instead, you arrange for the sender and receiver to already have one. It can't be built specifically for every string, but you can have a single global tree used to encode all strings. If you build it from the same language as the input strings (English or whatever), you should still get good compression, although not as good as with a custom tree for every input.
dependencies
Dependencies that your project needs to run, like a library that provides functions that you call from your code.
They are installed transitively (if A depends on B depends on C, npm install on A will install B and C).
Example: lodash: your project calls some lodash functions.
devDependencies
Dependencies you only need during development or releasing, like compilers that take your code and compile it into javascript, test frameworks or documentation generators.
They are not installed transitively (if A depends on B dev-depends on C, npm install on A will install B only).
Example: grunt: your project uses grunt to build itself.
peerDependencies
Dependencies that your project hooks into, or modifies, in the parent project, usually a plugin for some other library or tool. It is just intended to be a check, making sure that the parent project (project that will depend on your project) has a dependency on the project you hook into. So if you make a plugin C that adds functionality to library B, then someone making a project A will need to have a dependency on B if they have a dependency on C.
They are not installed (unless npm < 3), they are only checked for.
Example: grunt: your project adds functionality to grunt and can only be used on projects that use grunt.
This documentation explains peer dependencies really well: https://nodejs.org/en/blog/npm/peer-dependencies/
Also, the npm documentation has been improved over time, and now has better explanations of the different types of dependencies: https://github.com/npm/cli/blob/latest/docs/content/configuring-npm/package-json.md#devdependencies
you should do as:
getline(name, sizeofname, '\n');
strtok(name, " ");
This will give you the "joht" in name then to get next token,
temp = strtok(NULL, " ");
temp will get "smith" in it. then you should use string concatination to append the temp at end of name. as:
strcat(name, temp);
(you may also append space first, to obtain a space in between).
I'm going to make a few assumptions and come at the problem from a different angle... in that because you have skype installed and running on the same machine, that it is not a production machine and instead used for testing / development?
If so, you may wish to look at alternatives to IIS completely to alleviate your issue. If you use IISExpress or the web server built into recent versions of Visual Studio, they will automatically pick a port for you.
Of course this does mean that it's not particularly useful for giving other people access, but is fine for local development for personal use.
I think the other answers probably offer a better alternative in most situations, but this may offer a different insight.
Here is an intro to IIS Express: http://learn.iis.net/page.aspx/860/iis-express/
I like the accepted answer a lot, but it stopped working in Chrome. In Chrome, for the cursor to go to the end, input value needs to change. The solution is as follow:
<input id="search" type="text" value="mycurrtext" size="30"
onfocus="var value = this.value; this.value = null; this.value = value;" name="search"/>
If you have >100 images that you want to have drop shadows for, I would suggest using the command-line program ImageMagick. With this, you can apply shaped drop shadows to 100 images just by typing one command! For example:
for i in "*.png"; do convert $i '(' +clone -background black -shadow 80x3+3+3 ')' +swap -background none -layers merge +repage "shadow/$i"; done
The above (shell) command takes each .png file in the current directory, applies a drop shadow, and saves the result in the shadow/ directory. If you don't like the drop shadows generated, you can tweak the parameters a lot; start by looking at the documentation for shadows, and the general usage instructions have a lot of cool examples of things that can be done to images.
If you change your mind in the future about the look of the drop shadows - it's just one command to generate new images with different parameters :-)
I resolved this, oddly enough, by installing System.Data.SQLite via the Nuget GUI application, as opposed to the package manager console.
Installing via the console didn't include the dependencies this library needs to run.
This might be useful for someone who is looking for a different answer. Go to the Gradle Panel and select your module -> Task -> Verification -> Check.

In MacOS Catalina 10.15.5 the .npmrc
file path can be found at
/Users/<user-name>/.npmrc
Open in it in (for first time users, create a new file) any editor and copy-paste your token. Save it.
You are ready to go.
Note:
As mentioned by @oligofren, the command npm config ls -l
will npm configurations. You will get the .npmrc file from config parameter userconfig

I had the very same error message. Finally I figured out I misspelled the name of the table in the command:
ALTER TABLE `users` ADD FOREIGN KEY (country_id) REFERENCES country (id);
versus
ALTER TABLE `users` ADD FOREIGN KEY (country_id) REFERENCES countries (id);
I wonder why on earth MySQL cannot tell such a table does not exist...
When I was recently looking for an R function returning indexes of top N max/min numbers in a given vector, I was surprised there is no such a function.
And this is something very similar.
The brute force solution using base::order function seems to be the easiest one.
topMaxUsingFullSort <- function(x, N) {
sort(x, decreasing = TRUE)[1:min(N, length(x))]
}
But it is not the fastest one in case your N value is relatively small compared to length of the vector x.
On the other side if the N is really small, you can use base::whichMax function iteratively and in each iteration you can replace found value by -Inf
# the input vector 'x' must not contain -Inf value
topMaxUsingWhichMax <- function(x, N) {
vals <- c()
for(i in 1:min(N, length(x))) {
idx <- which.max(x)
vals <- c(vals, x[idx]) # copy-on-modify (this is not an issue because idxs is relative small vector)
x[idx] <- -Inf # copy-on-modify (this is the issue because data vector could be huge)
}
vals
}
I believe you see the problem - the copy-on-modify nature of R. So this will perform better for very very very small N (1,2,3) but it will rapidly slow down for larger N values. And you are iterating over all elements in vector x N times.
I think the best solution in clean R is to use partial base::sort.
topMaxUsingPartialSort <- function(x, N) {
N <- min(N, length(x))
x[x >= -sort(-x, partial=N)[N]][1:N]
}
Then you can select the last (Nth) item from the result of functions defiend above.
Note: functions defined above are just examples - if you want to use them, you have to check/sanity inputs (eg. N > length(x)).
I wrote a small article about something very similar (get indexes of top N max/min values of a vector) at http://palusga.cz/?p=18 - you can find here some benchmarks of similar functions I defined above.
I save files in .XLSB format to cut size. The XLSB also allows for VBA and macros to stay with the file. I've seen 50 meg files down to less than 10 with the Binary formatting.
The -jar
option only works if the JAR file is an executable JAR file, which means it must have a manifest file with a Main-Class
attribute in it.
If it's not an executable JAR, then you'll need to run the program with something like:
java -cp app.jar com.somepackage.SomeClass
where com.somepackage.SomeClass
is the class that contains the main
method to run the program.
The highest rated answers to this question all recommend "ALTER yourtable AUTO_INCREMENT= value". However, this only works when value
in the alter is greater than the current max value of the autoincrement column. According to the MySQL 8 documentation:
You cannot reset the counter to a value less than or equal to the value that is currently in use. For both InnoDB and MyISAM, if the value is less than or equal to the maximum value currently in the AUTO_INCREMENT column, the value is reset to the current maximum AUTO_INCREMENT column value plus one.
In essence, you can only alter AUTO_INCREMENT to increase the value of the autoincrement column, not reset it to 1, as the OP asks in the second part of the question. For options that actually allow you set the AUTO_INCREMENT downward from its current max, take a look at Reorder / reset auto increment primary key.
@RequestParam is use for query parameter(static values) like: http://localhost:8080/calculation/pow?base=2&ext=4
@PathVariable is use for dynamic values like : http://localhost:8080/calculation/sqrt/8
@RequestMapping(value="/pow", method=RequestMethod.GET)
public int pow(@RequestParam(value="base") int base1, @RequestParam(value="ext") int ext1){
int pow = (int) Math.pow(base1, ext1);
return pow;
}
@RequestMapping("/sqrt/{num}")
public double sqrt(@PathVariable(value="num") int num1){
double sqrtnum=Math.sqrt(num1);
return sqrtnum;
}
Because SQL Server performs integer division. Try this:

My class libraries were definitely all referencing both System.Core and Microsoft.CSharp. Web Application was 4.0 and couldn't upgrade to 4.5 due to support issues.
I was encountering the error compiling a razor template using the Razor Engine, and only encountering it intermittently, like after web application has been restarted.
The solution that worked for me was manually loading the assembly then reattempting the same operation...
bool retry = true;
while (retry)
{
try
{
string textTemplate = File.ReadAllText(templatePath);
Razor.CompileWithAnonymous(textTemplate, templateFileName);
retry = false;
}
catch (TemplateCompilationException ex)
{
LogTemplateException(templatePath, ex);
retry = false;
if (ex.Errors.Any(e => e.ErrorNumber == "CS1969"))
{
try
{
_logger.InfoFormat("Attempting to manually load the Microsoft.CSharp.RuntimeBinder.Binder");
Assembly csharp = Assembly.Load("Microsoft.CSharp, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a");
Type type = csharp.GetType("Microsoft.CSharp.RuntimeBinder.Binder");
retry = true;
}
catch(Exception exLoad)
{
_logger.Error("Failed to manually load runtime binder", exLoad);
}
}
if (!retry)
throw;
}
}
Hopefully this might help someone else out there.
A solution I tend to use more and more is this one:
import matplotlib.pyplot as plt
fig, axs = plt.subplots(2, 2) # 1
for i, ax in enumerate(axs.ravel()): # 2
ax.set_title("Plot #{}".format(i)) # 3
According to bitbucket knowledgebase it may also be caused by the owner of the repository being over the plan limit.
If you look further down the page it seems to also be possible to trig this error by using a too old git version (1.7 is needed at the moment).
For MySql Server 8.0 The default location is %WINDIR% or C:\Windows.
You need to add a "my.ini" file there.
Here's a sample of what I put in the ini file.
[mysqld]

Make sure to restart the MySQL service after that.
Maybe better to make an anchor with DeleteJob url instead of button?
<a href="<%=Url.Action("DeleteJob", "YourController", new {selectedObject="someObject"})%>" onclick="return DeleteJob()">Löschen</a>
and use your javascript you wrote already:
function DeleteJob() {
if (confirm("Do you really want to delete selected job/s?"))
return true;
else
return false;
}
So if function return true - you will be redirected. If function return false - you still stay on the page.

orphanRemoval
has nothing to do with ON DELETE CASCADE
.
orphanRemoval
is an entirely ORM-specific thing. It marks "child" entity to be removed when it's no longer referenced from the "parent" entity, e.g. when you remove the child entity from the corresponding collection of the parent entity.
ON DELETE CASCADE
is a database-specific thing, it deletes the "child" row in the database when the "parent" row is deleted.
If you don't want to add a new column, and you can guarantee that your current int column is unique, you could select all of the data out into a temporary table, drop the table and recreate with the IDENTITY column specified. Then using SET IDENTITY INSERT ON
you can insert all of your data in the temporary table into the new table.
yo can extend your JS with a select method like this
Array.prototype.select = function(closure){
for(var n = 0; n < this.length; n++) {
if(closure(this[n])){
return this[n];
}
}
return null;
};
now you can use this:
var x = [1,2,3,4];
var a = x.select(function(v) {
return v == 2;
});
console.log(a);
or for objects in a array
var x = [{id: 1, a: true},
{id: 2, a: true},
{id: 3, a: true},
{id: 4, a: true}];
var a = x.select(function(obj) {
return obj.id = 2;
});
console.log(a);
Here's a more manual method that works both for Website projects and Web Application projects. (you can't change the project URL from within Visual Studio for Website projects.)
Web Application projects
In Solution Explorer, right-click the project and click Unload Project.
Navigate to the IIS Express ApplicationHost.config file. By default, this file is located in:
%userprofile%\Documents\IISExpress\config
In recent Visual Studio versions and Web Application projects, this file is in the solution folder under [Solution Dir]\.vs\config\applicationhost.config
(note the .vs folder is a hidden item)
Open the ApplicationHost.config file in a text editor. In the <sites>
section, search for your site's name. In the <bindings>
section of your site, you will see an element like this:
<binding protocol="http" bindingInformation="*:56422:localhost" />
Change the port number (56422 in the above example) to anything you want. e.g.:
<binding protocol="http" bindingInformation="*:44444:localhost" />
Bonus: You can even bind to a different host name and do cool things like:
<binding protocol="http" bindingInformation="*:80:mysite.dev" />
and then map mysite.dev
to 127.0.0.1
in your hosts
file, and then open your website from "http://mysite.dev"
In Solution Explorer, right-click the the project and click Reload Project.
In Solution Explorer, right-click the the project and select Properties.
Select the Web tab.
In the Servers section, under Use Local IIS Web server, in the Project URL box enter a URL to match the hostname and port you entered in the ApplicationHost.config file from before.
To the right of the Project URL box, click Create Virtual Directory. If you see a success message, then you've done the steps correctly.
In the File menu, click Save Selected Items.
Website projects
In Solution Explorer, right-click the project name and then click Remove or Delete; don't worry, this removes the project from your solution, but does not delete the corresponding files on disk.
Follow step 2 from above for Web Application projects.
In Solution Explorer, right-click the solution, select Add, and then select Existing Web Site.... In the Add Existing Web Site dialog box, make sure that the Local IIS tab is selected. Under IIS Express Sites, select the site for which you have changed the port number, then click OK.
Now you can access your website from your new hostname/port.
Bind the socket to port 0. A random free port from 1024 to 65535 will be selected. You may retrieve the selected port with getsockname()
right after bind()
.
Bruno's answer was the correct one in the end. This is most easily controlled by the https.protocols
system property. This is how you are able to control what the factory method returns. Set to "TLSv1" for example.
br { padding: 1px 8px; border-bottom: 1px dashed #000 }
renders as below in IE8... not a lot of use in just one browser though.
(N.B. I'm using IE 8.0.7100 (on Win7 RC) if that makes any difference)
Also,
br:after { content: "..." }
br { content: "" }`
or,
br:after {
border: 1px none black;
border-bottom-style: dashed;
content: "";
padding: 0 6px 0;
}
br { content: "" }
gives a dashed line in Chrome 2 / Safari 4b but loses the line break which (unless anyone can come up with a way to reintroduce that) makes it less than useless.
e.g.
IE8 test, Chrome/Safari test and another
Changing php.ini
for a web application requires restarting Apache.
You should verify that the change took place by running a PHP script that executes the function phpinfo()
. The output of that function will tell you a lot of PHP parameters, including the timeout value.
You might also have changed a copy of php.ini
that is not the same file used by Apache.
Steps:
All the commands and variables which begin with that letter are now going to appear
The sizeof the structure should be 8 bytes on a 32 bit system, so that the size of the structure becomes multiple of 2. This makes individual structures available at the correct byte boundaries when an array of structures is declared. This is achieved by padding the structure with 3 bytes at the end.
If the structure had the pointer declared after the char, it would still be 8 bytes in size but the 3 byte padding would have been added to keep the pointer (which is a 4 byte element) aligned at a 4 byte address boundary.
The rule of thumb is that elements should be at an offset which is the multiple of their byte size and the structure itself should be of a size which is a multiple of 2.
Looping helps:
for row in matrix:
print ' '.join(row)
or use nested str.join()
calls:
print '\n'.join([' '.join(row) for row in matrix])
Demo:
>>> matrix = [['A', 'B', 'C', 'D', 'E'], ['A', 'B', 'C', 'D', 'E'], ['A', 'B', 'C', 'D', 'E'], ['A', 'B', 'C', 'D', 'E'], ['A', 'B', 'C', 'D', 'E']]
>>> for row in matrix:
... print ' '.join(row)
...
A B C D E
A B C D E
A B C D E
A B C D E
A B C D E
>>> print '\n'.join([' '.join(row) for row in matrix])
A B C D E
A B C D E
A B C D E
A B C D E
A B C D E
If you wanted to show the rows and columns transposed, transpose the matrix by using the zip()
function; if you pass each row as a separate argument to the function, zip()
recombines these value by value as tuples of columns instead. The *args
syntax lets you apply a whole sequence of rows as separate arguments:
>>> for cols in zip(*matrix): # transposed
... print ' '.join(cols)
...
A A A A A
B B B B B
C C C C C
D D D D D
E E E E E
With : i << 2
const data = context.getImageData(x, y, width, height).data;
const pixels = [];
for (let i = 0, dx = 0; dx < data.length; i++, dx = i << 2) {
if (data[dx+3] <= 8)
console.log("transparent x= " + i);
}
To exclude content and subdirectories:
**/bin/*
To just exclude all subdirectories but take the content, add "/":
**/bin/*/
You can use querySelectorAll:
document.querySelectorAll('[data-foo]');
For Bootstrap 3 for collapse, if you don't specify data-target on the anchor and rely on href to determine the target, the event will be prevented. If you use data-target you'll need to prevent the event yourself.
<button type="button" class="btn btn-default" data-toggle="collapse" data-target="#demo">Collapse This</button>
<div id="demo" class="collapse">
<p>Lorem ipsum dolor sit amet</p>
</div>
You can do this:
[[ ! -f "$FILE" ]] && echo "File doesn't exist"
or
if [[ ! -f "$FILE" ]]; then
echo "File doesn't exist"
fi
If you want to check for file and folder both, then use -e
option instead of -f
. -e
returns true for regular files, directories, socket, character special files, block special files etc.
labelTV.setGravity(Gravity.CENTER | Gravity.BOTTOM);
Kotlin version (thanks to Thommy)
labelTV.gravity = Gravity.CENTER_HORIZONTAL or Gravity.BOTTOM
Also, are you talking about gravity or about layout_gravity? The latter won't work in a RelativeLayout.
You can configure this in mysql configuration file
open /etc/my.cnf

In this file all the lines which is configuring the password policy make those commented like
#validate-password=FORCE_PLUS_PERMANENT
#validate_password_length=10
#validate_password_mixed_case_count=1
#validate_password_number_count=1
#validate_password_policy=MEDIUM
Uncomment and change the value of the properties you want to change.
Unless your app is using some special encryption you can simply add Boolean a key to your Info.plist
with name ITSAppUsesNonExemptEncryption
and value NO
.
If your app is using custom encryption then you will need to provide extra legal documents and go through a review of your encryption before being able to select builds.
If you continue with selecting that version for testing, it will ask for the compliance information manually. Choosing "No" presents you with the plist recommendation above.
This is change has been announced in the 2015 WWDC, but I guess it has been enforced only very recently. See this and this for a transcript of the WWDC session related to the export compliance, just to a text search for "export".
There are other similar questions on SO, see:
Now docker-compose
supports variable substitution.
Compose uses the variable values from the shell environment in which docker-compose
is run. For example, suppose the shell contains POSTGRES_VERSION=9.3
and you supply this configuration in your docker-compose.yml
file:
db:
image: "postgres:${POSTGRES_VERSION}"
When you run docker-compose up
with this configuration, Compose looks for the POSTGRES_VERSION
environment variable in the shell and substitutes its value in. For this example, Compose resolves the image
to postgres:9.3
before running the configuration.
You can get around this by using the simulator if you don't actually need to be deploying to a device. That solved it for me.
For those finding this question in dotnet core. I found a solution here
Code:
private void OpenUrl(string url)
{
try
{
Process.Start(url);
}
catch

if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
{
url = url.Replace("&", "^&");
Process.Start(new ProcessStartInfo("cmd", $"/c start {url}") { CreateNoWindow = true });
}
else if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
{
Process.Start("xdg-open", url);
}
else if (RuntimeInformation.IsOSPlatform(OSPlatform.OSX))
{
Process.Start("open", url);
}
else
{
throw;
}
}
}
Or maybe
background: transparent !important;

Sort of:
class some_class {
static std::vector<std::string> v; // declaration
};
const char *vinit[] = {"one", "two", "three"};
std::vector<std::string> some_class::v(vinit, end(vinit)); // definition
end
is just so I don't have to write vinit+3
and keep it up to date if the length changes later. Define it as:
template<typename T, size_t N>
T * end(T (&ra)[N]) {
return ra + N;
}
The best practice is to reference the WSDL and use it like a web service reference. It's easier and works better, but if you don't have the WSDL, the XSD definitions are a good piece of code.

You either have to make the method Shared
or use an instance of the class General
:
Dim gen = New General()
gen.updateDynamics(get_prospect.dynamicsID)
or
General.updateDynamics(get_prospect.dynamicsID)
Public Shared Sub updateDynamics(dynID As Int32)
' ... '
End Sub
Add quotation marks (" ") around the %INPUT% so it looks like this:
If "%INPUT%" == "y" goto yes
If "%INPUT%" == "n" goto no
If "%INPUT%" == "Y" goto yes
If "%INPUT%" == "N" goto no
You can still use map
if you can afford to create a makeshift array:
{
new Array(this.props.level).fill(0).map((_, index) => (
<span className='indent' key={index}></span>
))
}
This works because new Array(n).fill(x)
creates an array of size n
filled with x
, which can then aid map
.
Are you referring to address validation? Like the previous answer by Mike, you need to cater for the othe 95%.
What you can do is when the user select's their country, then enable validation. Address validation and zipcode validation are 2 different things. Validating the ZIP is just making sure its integer. Address validation is validating the actual address for accuracy, preferably for mailing.
In java, an array is an object. Therefore the call to arl.get(0) returns a primitive int[] object which appears as ascii in your call to System.out.
The answer to your first question is therefore
System.out.println("Arraylist contains:"+Arrays.toString( arl.get( 0 ) ) );
If you're looking for particular elements, the returned int[] object must be referenced as such. The answer to your second question would be something like
int[] contentFromList = arl.get(0);
for (int i = 0; i < contentFromList.length; i++) {
int j = contentFromList[i];
System.out.println("Value at index - "+i+" is :"+j);
}
In your class, where you implement the static function, you can call a private\public method from this class. The private\public method can access the getResources.
for example:
public class Text {
public static void setColor(EditText et) {
et.resetColor(); // it works
// ERROR
et.setTextColor(getResources().getColor(R.color.Black)); // ERROR
}
// set the color to be black when reset
private void resetColor() {
setTextColor(getResources().getColor(R.color.Black));
}
}
and from other class\activity, you can call:
Text.setColor('some EditText you initialized');
This is what I did

Another way to do simultaneous animations if you want to call them separately (eg. from different code) is to use queue
. Again, as with Tinister's answer you would have to use animate for this and not fadeIn:
$('.tooltip').css('opacity', 0);
$('.tooltip').show();
...
$('.tooltip').animate({opacity: 1}, {queue: false, duration: 'slow'});
$('.tooltip').animate({ top: "-10px" }, 'slow');
Probably the jstl libraries are missing from your classpath/not accessible by tomcat.
You need to add at least the following jar files in your WEB-INF/lib
directory:
public void callingMethod(Class neededClass) {
//Cast the class to the class you need
//and call your method in the class
((ClassBeingCalled)neededClass).methodOfClass();
}
To call the method, you call it this way:
callingMethod(ClassBeingCalled.class);
Factory pattern creates a concrete implementation of a class at runtime, i.e its main intention is to use polymorphism to allow subclasses decide which class to instantiate. This means at compile time we dont know the exact class that will be created, while Builder pattern is mainly concerned with solving the problem of telescoping constructors antipattern, which arises due to a large number of optional fields of a class. In builder pattern there is no notion of polymorphism, as we know what object we are trying to construct at compile time.
The only common theme of these two patterns is the hiding of constructors and object creation behind factory methods, and the build method, for improved object construction.
The fastest way is to check if there is a non letter:
if (!/[^a-zA-Z]/.test(word))
If you need just logical value (as it almost always is), the following one-liner will help you:
boolean ifIntsEqual = !((Math.max(a,b) - Math.min(a, b)) > 0);
And it works even in Java 1.5+, maybe even in 1.1 (i don't have one). Please tell us, if you can test it in 1.5-.
This one will do too:
boolean ifIntsEqual = !((Math.abs(a-b)) > 0);
The condition below:
//Element[@attribute1="abc" and @attribute2="xyz" and Data]
checks for the existence of the element Data within Element and not for element value Data.
Instead you can use
//Element[@attribute1="abc" and @attribute2="xyz" and text()="Data"]

I got error sometimes when using $(`code`)

Finally i got some approach to that here: https://stackoverflow.com/a/7902174/2480481
Basically, using Tee to read again the ouput and putting it into a variable. Theres how you see the normal output then read it from the ouput.
is not? I guess your current task genhash will output just that, a single string hash so might work for you.
Im so neewbie and still looking for full output & save into 1 command. Regards.
There are many cases when small differences between environments can bite you. This is one into which I have ran recently. What is the difference between these two commands?
1 ~ $ nohup myprocess.out &
2 ~ $ myprocess.out &
The answer is the same as usual - it depends.
nohup catches the hangup signal while the ampersand does not.
What is the hangup signal?
SIGHUP - hangup detected on controlling terminal or death of controlling process (value: 1).
Normally, when running a command using & and exiting the shell afterwards, the shell will terminate the sub-command with the hangup signal (like kill -SIGHUP $PID). This can be prevented using nohup, as it catches the signal and ignores it so that it never reaches the actual application.
Fine, but like in this case there are always ‘buts’. There is no difference between these launching methods when the shell is configured in a way where it does not send SIGHUP at all.
In case you are using bash, you can use the command specified below to find out whether your shell sends SIGHUP to its child processes or not:
~ $ shopt | grep hupon
And moreover - there are cases where nohup does not work. For example, when the process you start reconnects the NOHUP signal (it is done inside, on the application code level).
In the described case, lack of differences bit me when inside a custom service launching script there was a call to a second script which sets up and launches the proper application without a nohup command.
On one Linux environment everything worked smoothly, on a second one the application quit as soon as the second script exited (detecting that case, of course took me much more time then you might think :stuck_out_tongue:).
After adding nohup as a launching method to second script, application keeps running even if the scripts will exit and this behavior became consistent on both environments.

I have tried to make this example as detailed as possible. Do ask if you have any queries.
ran into this problem today and wanted to include NaNs so I replace them temporarily with "" (empty string). Please comment if you do not understand something :). This solution assumes that "" is not a relevant value for you. It should also work with numerical data (I have tested it sucessfully but not extensively) since pandas will infer the data type again after replacing "" with np.nan.
import pandas as pd
# create test data
df = pd.DataFrame({'test':['foo','bar',None,None,'foo'],
'test2':['bar',None,None,None,'bar'],
'test3':[None, 'foo','bar',None,None]})
# fill null values with '' to not lose them during groupby
# groupby all columns and calculate the length of the resulting groups
# rename the series obtained with groupby to "group_count"
# reset the index to get a DataFrame
# replace '' with np.nan (this reverts our first operation)
# sort DataFrame by "group_count" descending
df = (df.fillna('')\
.groupby(df.columns.tolist()).apply(len)\
.rename('group_count')\
.reset_index()\
.replace('',np.nan)\
.sort_values(by = ['group_count'], ascending = False))
df
test test2 test3 group_count
3 foo bar NaN 2
0 NaN NaN NaN 1
1 NaN NaN bar 1
2 bar NaN foo 1
Don't just say "memory pool of strings is reused in the literal form, case closed". What compilers do under the hood is not the point here. The question is reasonable, specially given the number of up-votes it received.
It's about the symmetry, without it APIs are harder to use for humans. Early Java SDKs notoriously ignored the rule and now it's kind of too late. Here are a few examples on top of my head, feel free to chip in your "favorite" example:
I certainly don't know the details on this because I've never done it it, but the native NT API has a capability to fork a process (the POSIX subsystem on Windows needs this capability - I'm not sure if the POSIX subsystem is even supported anymore).
A search for ZwCreateProcess() should get you some more details - for example this bit of information from Maxim Shatskih:
The most important parameter here is SectionHandle. If this parameter is NULL, the kernel will fork the current process. Otherwise, this parameter must be a handle of the SEC_IMAGE section object created on the EXE file before calling ZwCreateProcess().
Though note that Corinna Vinschen indicates that Cygwin found using ZwCreateProcess() still unreliable:
Iker Arizmendi wrote:
> Because the Cygwin project relied solely on Win32 APIs its fork > implementation is non-COW and inefficient in those cases where a fork > is not followed by exec. It's also rather complex. See here (section > 5.6) for details: > > http://www.redhat.com/support/wpapers/cygnus/cygnus_cygwin/architecture.html
This document is rather old, 10 years or so. While we're still using Win32 calls to emulate fork, the method has changed noticably. Especially, we don't create the child process in the suspended state anymore, unless specific datastructes need a special handling in the parent before they get copied to the child. In the current 1.5.25 release the only case for a suspended child are open sockets in the parent. The upcoming 1.7.0 release will not suspend at all.
One reason not to use ZwCreateProcess was that up to the 1.5.25 release we're still supporting Windows 9x users. However, two attempts to use ZwCreateProcess on NT-based systems failed for one reason or another.
It would be really nice if this stuff would be better or at all documented, especially a couple of datastructures and how to connect a process to a subsystem. While fork is not a Win32 concept, I don't see that it would be a bad thing to make fork easier to implement.

Concatenate with & operator
Dim str as String 'no need to create a string instance
str = "Hello " & "World"
You can concate with the + operator as well but you can get yourself into trouble when trying to concatenate numbers.
Concatenate with String.Concat()
str = String.Concat("Hello ", "World")
Useful when concatenating array of strings
StringBuilder.Append()
When concatenating large amounts of strings use StringBuilder, it will result in much better performance.
Dim sb as new System.Text.StringBuilder()
str = sb.Append("Hello").Append(" ").Append("World").ToString()
Strings in .NET are immutable, resulting in a new String object being instantiated for every concatenation as well a garbage collection thereof.
There is also an easy way for copying via the clipboard:
Use split
and map
function:
var str = "123, 124, 234,252";
var arr = str.split(",");
arr = arr.map(function (val) { return +val + 1; });
Notice +val
- string is casted to a number.
Or shorter:
var str = "123, 124, 234,252";
var arr = str.split(",").map(function (val) { return +val + 1; });
Today I'd advise against using +
operator to cast variable to a number. Instead I'd go with a more explicit but also more readable Number
call:
var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(function (val) {_x000D_
return Number(val) + 1;_x000D_
});_x000D_
console.log(arr);
_x000D_
ECMAScript 2015 introduced arrow function so it could be used instead to make the code more concise:
var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(val => Number(val) + 1);_x000D_
console.log(arr);
_x000D_
You don't really need all that much code:
IFS=$'\n' sorted=($(sort <<<"${array[*]}"))
unset IFS
Supports whitespace in elements (as long as it's not a newline), and works in Bash 3.x.
e.g.:
$ array=("a c" b f "3 5")
$ IFS=$'\n' sorted=($(sort <<<"${array[*]}")); unset IFS
$ printf "[%s]\n" "${sorted[@]}"
[3 5]
[a c]
[b]
[f]
Note: @sorontar has pointed out that care is required if elements contain wildcards such as *
or ?
:
The sorted=($(...)) part is using the "split and glob" operator. You should turn glob off:
set -f
orset -o noglob
orshopt -op noglob
or an element of the array like*
will be expanded to a list of files.
The result is a culmination six things that happen in this order:
IFS=$'\n'
"${array[*]}"
<<<
sort
sorted=($(...))
unset IFS
IFS=$'\n'
This is an important part of our operation that affects the outcome of 2 and 5 in the following way:
Given:
"${array[*]}"
expands to every element delimited by the first character of IFS
sorted=()
creates elements by splitting on every character of IFS
IFS=$'\n'
sets things up so that elements are expanded using a new line as the delimiter, and then later created in a way that each line becomes an element. (i.e. Splitting on a new line.)
Delimiting by a new line is important because that's how sort
operates (sorting per line). Splitting by only a new line is not-as-important, but is needed preserve elements that contain spaces or tabs.
The default value of IFS
is a space, a tab, followed by a new line, and would be unfit for our operation.
sort <<<"${array[*]}"
part<<<
, called here strings, takes the expansion of "${array[*]}"
, as explained above, and feeds it into the standard input of sort
.
With our example, sort
is fed this following string:
a c
b
f
3 5
Since sort
sorts, it produces:
3 5
a c
b
f
sorted=($(...))
partThe $(...)
part, called command substitution, causes its content (sort <<<"${array[*]}
) to run as a normal command, while taking the resulting standard output as the literal that goes where ever $(...)
was.
In our example, this produces something similar to simply writing:
sorted=(3 5
a c
b
f
)
sorted
then becomes an array that's created by splitting this literal on every new line.
unset IFS
This resets the value of IFS
to the default value, and is just good practice.
It's to ensure we don't cause trouble with anything that relies on IFS
later in our script. (Otherwise we'd need to remember that we've switched things around--something that might be impractical for complex scripts.)

The necessary method is Mockito#verify:
public static <T> T verify(T mock,
VerificationMode mode)
mock
is your mocked object and mode
is the VerificationMode
that describes how the mock should be verified. Possible modes are:
verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");
You'll need these static imports from the Mockito
class in order to use the verify
method and these verification modes:
import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
So in your case the correct syntax will be:
Mockito.verify(mock, times(4)).send()
This verifies that the method send
was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.
If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode
. A simple
verify(mock).someMethod("was called once");
would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");
.
It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");
, but we can write
verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");
instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.
Use subprocess.check_output
(new in python 2.7). It will suppress stdout and raise an exception if the command fails. (It actually returns the contents of stdout, so you can use that later in your program if you want.) Example:
import subprocess
try:
subprocess.check_output(['espeak', text])
except subprocess.CalledProcessError:
# Do something
You can also suppress stderr with:
subprocess.check_output(["espeak", text], stderr=subprocess.STDOUT)
For earlier than 2.7, use
import os
import subprocess
with open(os.devnull, 'w') as FNULL:
try:
subprocess._check_call(['espeak', text], stdout=FNULL)
except subprocess.CalledProcessError:
# Do something
Here, you can suppress stderr with
subprocess._check_call(['espeak', text], stdout=FNULL, stderr=FNULL)
Original answer:
I too tried to change the support library to "23". When I changed the targetSdkVersion
to 23, Android Studio reported the following error:
This support library should not use a lower version (22) than the
targetSdkVersion
(23)
I simply changed:
compile 'com.android.support:appcompat-v7:23.0.0'
to
compile 'com.android.support:appcompat-v7:+'
Although this fixed my issue, you should not use dynamic versions. After a few hours the new support repository was available and it is currently 23.0.1
.
Pro tip:
You can use double quotes and create a ${supportLibVersion}
variable for simplicity. Example:
ext {
supportLibVersion = '23.1.1'
}
compile "com.android.support:appcompat-v7:${supportLibVersion}"
compile "com.android.support:design:${supportLibVersion}"
compile "com.android.support:palette-v7:${supportLibVersion}"
compile "com.android.support:customtabs:${supportLibVersion}"
compile "com.android.support:gridlayout-v7:${supportLibVersion}"

Well Lorenz Lo Sauer already have a good question for this. but if you want to resolve this problem through the Pycharm Tuning (without turning off Pycharm code inspection). you can tuning the heap size as you need. since I prefer to use increasing Heap Size solution for slow running Pycharm Application.
You can tune up Heap Size by editing pycharm.exe.vmoptions file. and pycharm64.exe.vmoptions for 64bit application. and then edit -Xmx and -Xms value on it.
So I allocate 2048m for xmx and xms value (which is 2GB) for my Pycharm Heap Size. Here it is My Configuration. I have 8GB memory so I had set it up with this setting:
-server
-Xms2048m
-Xmx2048m
-XX:MaxPermSize=2048m
-XX:ReservedCodeCacheSize=2048m
save the setting, and restart IDE. And I enable "Show memory indicator" in settings->Appearance & Behavior->Appearance. to see it in action :
and Pycharm is quick and running fine now.

After investigating lots of alternatives, I have come across another approach, suitable for the API 2.0 version.
(VB.NET is my favorite, sooo...)
Public Async Function APIPut_Response(ID as Integer, MyWidget as Widget) as Task(Of HttpResponseMessage)
Dim DesiredContent as HttpContent = New StringContent(JsonConvert.SerializeObject(MyWidget))
Return Await APIClient.PutAsync(String.Format("api/widget/{0}", ID), DesiredContent)
End Function
Good luck! For me this worked out (in the end!).

If it's running all of the above from the command line that you're looking for, then I'd recommend HTTPie. It is a fantastic cURL alternative and is super easy and convenient to use (and customize).
Here's is its (succinct and precise) description from GitHub;
HTTPie (pronounced aych-tee-tee-pie) is a command line HTTP client. Its goal is to make CLI interaction with web services as human-friendly as possible.
It provides a simple http command that allows for sending arbitrary HTTP requests using a simple and natural syntax, and displays colorized output. HTTPie can be used for testing, debugging, and generally interacting with HTTP servers.
The documentation around authentication should give you enough pointers to solve your problem(s). Of course, all of the answers above are accurate as well, and provide different ways of accomplishing the same task.
Just so you do NOT have to move away from Stack Overflow, here's what it offers in a nutshell.
Basic auth:_x000D_

if you use your website in the same network as the server IE likes to switch to compability mode despite DOCTYPE.
Adding meta http-equiv="X-UA-Compatible" content="IE=Edge"
disables this unwanted behaviour.
this problem is for CPU Architecture and you have some of the abi
in the lib
folder.
go to build.gradle
for your app module
and in android
, block add this :
splits {
abi {
enable true
reset()
include 'x86', 'armeabi-v7a'
universalApk true
}
}
Here is a basic example:
public class TestMethodPassing
{
private static void println()
{
System.out.println("Do println");
}
private static void print()
{
System.out.print("Do print");
}
private static void performTask(BasicFunctionalInterface functionalInterface)
{
functionalInterface.performTask();
}
@FunctionalInterface
interface BasicFunctionalInterface
{
void performTask();
}
public static void main(String[] arguments)
{
performTask(TestMethodPassing::println);
performTask(TestMethodPassing::print);
}
}
Output:
Do println
Do print
You can take update / pull on git branch you can use below command
git pull origin <branch-name>
The above command will take an update/pull from giving branch name
If you want to take pull from another branch, you need to go to that branch.
git checkout master
Than
git pull origin development
Hope that will work for you

Guido has written The Inside Story on New-Style Classes, a really great article about new-style and old-style class in Python.
Python 3 has only new-style class. Even if you write an 'old-style class', it is implicitly derived from object
.
New-style classes have some advanced features lacking in old-style classes, such as super
, the new C3 mro, some magical methods, etc.
If you're looking for the simplest way to check for a database object's existence before removing it, here's one way (example uses a SPROC, just like your example above but could be modified for tables, indexes, etc...):
IF (OBJECT_ID('MyProcedure') IS NOT NULL)
DROP PROCEDURE MyProcedure
GO
This is quick and elegant, but you need to make sure you have unique object names across all object types since it does not take that into account.
I Hope this helps!

uint16_t
is guaranteed to be a unsigned integer that is 16 bits large
unsigned short int
is guaranteed to be a unsigned short integer
, where short integer
is defined by the compiler (and potentially compiler flags) you are currently using. For most compilers for x86 hardware a short integer
is 16 bits large.
Also note that per the ANSI C standard only the minimum size of 16 bits is defined, the maximum size is up to the developer of the compiler
Minimum Type Limits
Any compiler conforming to the Standard must also respect the following limits with respect to the range of values any particular type may accept. Note that these are lower limits: an implementation is free to exceed any or all of these. Note also that the minimum range for a char is dependent on whether or not a char is considered to be signed or unsigned.
Type Minimum Range
signed char -127 to +127 unsigned char 0 to 255 short int -32767 to +32767 unsigned short int 0 to 65535

In Swift 3.0, you could use this code below:
let textLabel = UILabel(frame: CGRect(x:containerView.frame.width/2 - 35, y:
containerView.frame.height/2 + 10, width: 70, height: 20))
textLabel.text = "Add Text"
textLabel.font = UIFont(name: "Helvetica", size: 15.0) // set fontName and Size
textLabel.textAlignment = .center
containerView.addSubview(textLabel) // containerView is a UIView
The warning from your compiler is telling you that your format specifier doesn't match the data type you're passing to it.
Try using %lx
or %llx
. For more portability, include inttypes.h
and use the PRIx64
macro.
For example: printf("val = 0x%" PRIx64 "\n", val);
(note that it's string concatenation)
You could also do
function insertAfter(node1, node2) {
node1.outerHTML += node2.outerHTML;
}
or
function insertAfter2(node1, node2) {
var wrap = document.createElement("div");
wrap.appendChild(node2.cloneNode(true));
var node2Html = wrap.innerHTML;
node1.insertAdjacentHTML('afterend', node2Html);
}
You can try this
$query = mysql_query("SELECT * FROM $this_table") or die (mysql_error());
or this
$query = mysql_query("SELECT * FROM $this_table") or die ("Table does not exists!");
or this
$query = mysql_query("SELECT * FROM $this_table");
if(!$query)
echo "The ".$this_table." does not exists";
Hope it helps!

{
con.Open();
using (SqlCommand command = new SqlCommand("DELETE FROM " + table + " WHERE " + columnName + " = '" + IDNumber+"'", con))

}
con.Close();
}
}

{
MessageBox.Show(string.Format("An error occurred: {0}", ex.Message));
}
}
}
I was also faced by the posted issue when I used python 2.7. It is working very fine with python 3.4
To make it work in python 2.7 I have added the __metaclass__ = type
attribute at the top of my program and it worked.
__metaclass__
: It eases the transition from old-style classes and new-style classes.
Your code concatenates three strings, then converts the result to a number.
You need to convert each variable to a number by calling parseFloat()
around each one.
total = parseFloat(myInt1) + parseFloat(myInt2) + parseFloat(myInt3);
Just to clarify some of the great answers here, the steps outlined in many of the answers assume that you already have a remote repository somewhere.
Given: an existing git repository, e.g. [email protected]:some-user/full-repo.git
, with one or more directories that you wish to pull independently of the rest of the repo, e.g. directories named app1
and app2
Assuming you have a git repository as the above...
Then: you can run steps like the following to pull only specific directories from that larger repo:
mkdir app1
cd app1
git init
git remote add origin [email protected]:some-user/full-repo.git
git config core.sparsecheckout true
echo "app1/" >> .git/info/sparse-checkout
git pull origin master
I had mistakenly thought that the sparse-checkout options had to be set on the original repository, but this is not the case: you define which directories you want locally, prior to pulling from the remote. The remote repo doesn't know or care about your only wanting to track a part of the repo.
Hope this clarification helps someone else.
If this helps you,
<input type="checkbox" (ngModelChange)="mychange($event)" [ngModel]="mymodel">

You can create your own custom selector :hasValue
and then use that to find, filter, or test any other jQuery elements.
jQuery.expr[':'].hasValue = function(el,index,match) {
return el.value != "";
};
Then you can find elements like this:
var data = $("form input:hasValue").serialize();
Or test the current element with .is()
var elHasValue = $("#name").is(":hasValue");
jQuery.expr[':'].hasValue = function(el) {_x000D_
return el.value != "";_x000D_
};_x000D_

Further Reading:
Here is an example class using CSS named colors:
.semi-transparent {
background: yellow;
opacity: 0.25;
}
This adds a background that is 25% opaque (colored) and 75% transparent.
CAVEAT
Unfortunately, opacity will affect then entire element it's attached to.
So if you have text in that element, it will set the text to 25% opacity too. :-(
The way to get past this is to use the rgba
or hsla
methods to indicate transparency as part of your desired background "color". This allows you to specify the background transparency, independent from the transparency of the other items in your element.
Here are 3 ways to set a blue background at 75% transparency, without affecting other elements:
background: rgba(0%, 0%, 100%, 0.75)
background: rgba(0, 0, 255, 0.75)
background: hsla(240, 100%, 50%, 0.75)
You may take a look at the following article for writing a custom DataAnnotationsModelMetadataProvider
.
And here's another, more ASP.NET MVC 3ish way to proceed involving the newly introduced IMetadataAware interface.
Start by creating a custom attribute implementing this interface:
public class PlaceHolderAttribute : Attribute, IMetadataAware
{
private readonly string _placeholder;
public PlaceHolderAttribute(string placeholder)
{
_placeholder = placeholder;
}
public void OnMetadataCreated(ModelMetadata metadata)
{
metadata.AdditionalValues["placeholder"] = _placeholder;
}
}
And then decorate your model with it:
public class MyViewModel
{
[PlaceHolder("Enter title here")]
public string Title { get; set; }
}
Next define a controller:
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new MyViewModel());
}
}
A corresponding view:
@model MyViewModel
@using (Html.BeginForm())
{
@Html.EditorFor(x => x.Title)
<input type="submit" value="OK" />
}
And finally the editor template (~/Views/Shared/EditorTemplates/string.cshtml
):
@{
var placeholder = string.Empty;
if (ViewData.ModelMetadata.AdditionalValues.ContainsKey("placeholder"))
{
placeholder = ViewData.ModelMetadata.AdditionalValues["placeholder"] as string;
}
}
<span>
@Html.Label(ViewData.ModelMetadata.PropertyName)
@Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue, new { placeholder = placeholder })
</span>
I tried this and dont see any way of doing it.
here is my approach for it.
EXEC sp_rename 'Employee', 'Employee1'
-- Original table name is EmployeeINSERT INTO TABLE2 SELECT * FROM TABLE1
.
-- Insert into Employee select Name, Company from Employee1DROP table Employee1
.Have a look at Runtime.exec() Javadoc
Process p = Runtime.getRuntime().exec("ssh myhost");
PrintStream out = new PrintStream(p.getOutputStream());
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
out.println("ls -l /home/me");
while (in.ready()) {
String s = in.readLine();
System.out.println(s);
}
out.println("exit");
p.waitFor();
Alternatively, not to think about a newline or space somewhere in the file, you can buffer the output. Basically, you call ob_start()
at the very beginning of the file and ob_end_flush()
at the end. You can find more details at php.net ob-start function description.
Edit: If you use buffering, you can output HTML before and after header() function - buffering will then ignore the output and return only the redirection header.
I have been looking at this closely and all these answers don‘t seem to really show me all the commits across all the branches.
Here is what I have come up with by messing around with the gitk edit view options. This shows me all the commits for a file regardless of branch, local, reflog, and remote.
gitk --all --first-parent --remotes --reflog --author-date-order -- filename
It also works with git log
:
git log --all --first-parent --remotes --reflog --author-date-order -- filename

As you can see, I have the default colors and then I added the android:windowIsTranslucent
and set it to true
.
As far as I know as an Android Developer, this is the only thing you need to set in order to hide the white screen on the start of the application.
I would dump your query so you can take a look at the SQL that was actually executed and see how that differs from what you wrote.
You should be able to do that with the following code:
$queries = DB::getQueryLog();
$last_query = end($queries);
var_dump($last_query);
die();
Hopefully that should give you enough information to allow you to figure out what's gone wrong.
Check the length of the list given by of split() method.
if len(your_string.split()==0:
print("yes")
Or Compare output of strip() method with null.
if your_string.strip() == '':
print("yes")
I suspect there are many answers like this on SO but here you go:
if ( typeof pagetype !== 'undefined' && pagetype == 'textpage' ) {
...
}
You need to pass the variable into the function:
$data = 'My data';
function menugen($data)
{
echo $data;
}
You can also declare class variables as None which will prevent propagation. This is useful when you need a well defined class and want to prevent AttributeErrors. For example:
>>> class TestClass(object):
... t = None
...
>>> test = TestClass()
>>> test.t
>>> test2 = TestClass()
>>> test.t = 'test'
>>> test.t
'test'
>>> test2.t
>>>
Also if you need defaults:
>>> class TestClassDefaults(object):
... t = None
... def __init__(self, t=None):
... self.t = t
...
>>> test = TestClassDefaults()
>>> test.t
>>> test2 = TestClassDefaults([])
>>> test2.t
[]
>>> test.t
>>>
Of course still follow the info in the other answers about using mutable vs immutable types as the default in __init__
.
Do you by any chance have two PUBLICclass
classes in your project, where one is public (the one of which you posted the signature here), and another one which is package visible, and you import the wrong one in your code ?
Using balexandre's info:
SELECT usesysid, usename FROM pg_stat_activity;
I dislike having Docker environment variables when I do not expect user of a Docker image to change them.
Just put it somewhere in one RUN
. If you do not have UTF-8 locales generated, then you can do the following set of commands:
export DEBIAN_FRONTEND=noninteractive
apt-get update -q -q
apt-get install --yes locales
locale-gen --no-purge en_US.UTF-8
update-locale LANG=en_US.UTF-8
echo locales locales/locales_to_be_generated multiselect en_US.UTF-8 UTF-8 | debconf-set-selections
echo locales locales/default_environment_locale select en_US.UTF-8 | debconf-set-selections
dpkg-reconfigure locales
First Find PID # - where the Rails Server got stuck on
Run this to find the stuck PID
cat ./tmp/pids/server.pid
It will return something like 65829
Then KILL that PID => kill 65829
You would need to loop through the rows of each table, and then through each column within that loop to compare individual values.

For those who are writing Eclipse plugins and want to include the source...
in the feature ExportWizard there is an option for including the source:
Simple solution is to embed inside of a <textarea>
element, which will preserve both the formatting and the angle brackets. I have also removed the border with style="border:none;"
which makes the textarea invisible.
Here is a sample: http://jsfiddle.net/y9fqf/1/
