You can try
lstCountry.SelectedItem.Text
Drop root privileges after you bind to port 80 (or 443).
This allows port 80/443 to remain protected, while still preventing you from serving requests as root:
function drop_root() {
process.setgid('nobody');
process.setuid('nobody');
}
A full working example using the above function:
var process = require('process');
var http = require('http');
var server = http.createServer(function(req, res) {
res.write("Success!");
res.end();
});
server.listen(80, null, null, function() {
console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
drop_root();
console.log('User ID:',process.getuid()+', Group ID:',process.getgid());
});

It's treating the string application
as your URL.
This means your shell isn't parsing the command correctly.
My guess is that you copied the string from somewhere, and that when you pasted it, you got some characters that looked like regular quotes, but weren't.
Try retyping the command; you'll only get valid characters from your keyboard. I bet you'll get a much different result from what looks like the same query.
As this is probably a shell problem and not a 'curl' problem (you didn't build cURL yourself from source, did you?), it might be good to mention whether you're on Linux/Windows/etc.
You want $_SERVER['REQUEST_URI']
. From the docs:
'REQUEST_URI'
The URI which was given in order to access this page; for instance,
'/index.html'
.
When you override OnCreateView
in your RouteSearchFragment
class, do you have the
if(view != null) {
return view;
}
code segment?
If so, removing the return statement should solve your problem.
You can keep the code and return the view if you don't want to regenerate view data, and onDestroyView() method you remove this view from its parent like so:
@Override
public void onDestroyView() {
super.onDestroyView();
if (view != null) {
ViewGroup parent = (ViewGroup) view.getParent();
if (parent != null) {
parent.removeAllViews();
}
}
}
You can just use the Select()
extension method:
IEnumerable<int> integers = new List<int>() { 1, 2, 3, 4, 5 };
IEnumerable<string> strings = integers.Select(i => i.ToString());
Or in LINQ syntax:
IEnumerable<int> integers = new List<int>() { 1, 2, 3, 4, 5 };
var strings = from i in integers
select i.ToString();
You should look at the article C++ Programming/Type Casting.
It contains a good description of all of the different cast types. The following taken from the above link:
const_cast
const_cast(expression) The const_cast<>() is used to add/remove const(ness) (or volatile-ness) of a variable.
static_cast
static_cast(expression) The static_cast<>() is used to cast between the integer types. 'e.g.' char->long, int->short etc.
Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type.
dynamic_cast
Dynamic cast is used to convert pointers and references at run-time, generally for the purpose of casting a pointer or reference up or down an inheritance chain (inheritance hierarchy).
dynamic_cast(expression)
The target type must be a pointer or reference type, and the expression must evaluate to a pointer or reference. Dynamic cast works only when the type of object to which the expression refers is compatible with the target type and the base class has at least one virtual member function. If not, and the type of expression being cast is a pointer, NULL is returned, if a dynamic cast on a reference fails, a bad_cast exception is thrown. When it doesn't fail, dynamic cast returns a pointer or reference of the target type to the object to which expression referred.
reinterpret_cast
Reinterpret cast simply casts one type bitwise to another. Any pointer or integral type can be casted to any other with reinterpret cast, easily allowing for misuse. For instance, with reinterpret cast one might, unsafely, cast an integer pointer to a string pointer.
[System.IO.Directory]::CreateDirectory('full path to directory')
This internally checks for directory existence, and creates one, if there is no directory. Just one line and native .NET method working perfectly.
Use the helper classes VisualTreeHelper
or LogicalTreeHelper
depending on which tree you're interested in. They both provide methods for getting the children of an element (although the syntax differs a little). I often use these classes for finding the first occurrence of a specific type, but you could easily modify it to find all objects of that type:
public static DependencyObject FindInVisualTreeDown(DependencyObject obj, Type type)
{
if (obj != null)
{
if (obj.GetType() == type)
{
return obj;
}
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++)
{
DependencyObject childReturn = FindInVisualTreeDown(VisualTreeHelper.GetChild(obj, i), type);
if (childReturn != null)
{
return childReturn;
}
}
}
return null;
}
Tom Scott got it right in his coverage of how (not) to store passwords, on Computerphile.
https://www.youtube.com/watch?v=8ZtInClXe1Q
If you can at all avoid it, do not try to store passwords yourself. Use a separate, pre-established, trustworthy user authentication platform (e.g.: OAuth providers, you company's Active Directory domain, etc.) instead.
If you must store passwords, don't follow any of the guidance here. At least, not without also consulting more recent and reputable publications applicable to your language of choice.
There's certainly a lot of smart people here, and probably even some good guidance given. But the odds are strong that, by the time you read this, all of the answers here (including this one) will already be outdated.
All that said, here's some general guidance that will hopefully remain useful for awhile.
Process the passwords exactly as entered by the user during the creation process. Anything you do to the password before sending it to the cryptography module will probably just weaken it. Doing any of the following also just adds complexity to the password storage & verification process, which could cause other problems (perhaps even introduce vulnerabilities) down the road.
Reject creation of any passwords that can't be stored without modification. Reinforcing the above. If there's some reason your password storage mechanism can't appropriately handle certain characters, whitespaces, strings, or password lengths, then return an error and let the user know about the system's limitations so they can retry with a password that fits within them. For a better user experience, make a list of those limitations accessible to the user up-front. Don't even worry about, let alone bother, hiding the list from attackers - they'll figure it out easily enough on their own anyway.
Most importantly...
Go look up a reputable and very recent publication on the proper methods of password storage for your language of choice. Actually, you should find multiple recent publications from multiple separate sources that are in agreement before you settle on one method.
It's extremely possible that everything that everyone here (myself included) has said has already been superseded by better technologies or rendered insecure by newly developed attack methods. Go find something that's more probably not.
Should you instead be setting the identity insert to on within the stored procedure? It looks like you're setting it to on only when changing the stored procedure, not when actually calling it. Try:
ALTER procedure [dbo].[spInsertDeletedIntoTBLContent]
@ContentID int,
SET IDENTITY_INSERT tbl_content ON
...insert command...
SET IDENTITY_INSERT tbl_content OFF
GO

There's no need to check for EOF in python, simply do:
with open('t.ini') as f:

# For Python3, use print(line)
print line

It is good practice to use the
with
keyword when dealing with file objects. This has the advantage that the file is properly closed after its suite finishes, even if an exception is raised on the way.
the percent should be relative to an absolute size, try this :
table {
width:200px;
}
td {
width:65%;
border:1px solid black;
}
_x000D_
<table>
<tr>
<td>Testasdas 3123 1 dasd as da</td>
<td>A long string blah blah blah</td>
</tr>
</table>

Use CHARINDEX
. Perhaps make user function. If you use this split often.
I would create this function:
CREATE FUNCTION [dbo].[Split]
(
@String VARCHAR(max),
@Delimiter varCHAR(1)
)
RETURNS TABLE
AS
RETURN
(
WITH Split(stpos,endpos)
AS(
SELECT 0 AS stpos, CHARINDEX(@Delimiter,@String) AS endpos
UNION ALL
SELECT endpos+1, CHARINDEX(@Delimiter,@String,endpos+1)
FROM Split
WHERE endpos > 0
)
SELECT 'INT_COLUMN' = ROW_NUMBER() OVER (ORDER BY (SELECT 1)),
'STRING_COLUMN' = SUBSTRING(@String,stpos,COALESCE(NULLIF(endpos,0),LEN(@String)+1)-stpos)
FROM Split
)
GO
Use NetworkMonitor to monitoring network state and internet connection.
Sample:
namespace AmRoNetworkMonitor.Demo
{
using System;
internal class Program
{
private static void Main()
{
NetworkMonitor.StateChanged += NetworkMonitor_StateChanged;
NetworkMonitor.StartMonitor();
Console.WriteLine("Press any key to stop monitoring.");
Console.ReadKey();
NetworkMonitor.StopMonitor();
Console.WriteLine("Press any key to close program.");
Console.ReadKey();
}
private static void NetworkMonitor_StateChanged(object sender, StateChangeEventArgs e)
{
Console.WriteLine(e.IsAvailable ? "Is Available" : "Is Not Available");
}
}
}
what about this?
import sys
sys.stdin=open('fname','r')
data=sys.stdin.readlines()
print "counted",len(data),"lines"
Actually the following code is valid for API levels 5 and up, so if your target API is lower than this, you'll end up with something very similar to EboMike's code.
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
overridePendingTransition(0, 0);
With moment you can parse the date string you have:
var dt = moment(myDate.date, "YYYY-MM-DD HH:mm:ss")
That's for UTC, you'll have to convert the time zone from that point if you so desire.
Then you can get the day of the week:
dt.format('dddd');

Creating colnames with iterating
df = pd.DataFrame(columns=['colname_' + str(i) for i in range(5)])
print(df)
# Empty DataFrame
# Columns: [colname_0, colname_1, colname_2, colname_3, colname_4]
# Index: []
to_html()
operations
print(df.to_html())
# <table border="1" class="dataframe">
# <thead>
# <tr style="text-align: right;">
# <th></th>
# <th>colname_0</th>
# <th>colname_1</th>
# <th>colname_2</th>
# <th>colname_3</th>
# <th>colname_4</th>
# </tr>
# </thead>
# <tbody>
# </tbody>
# </table>
this seems working
print(type(df.to_html()))
# <class 'str'>
when you create df like this
df = pd.DataFrame(columns=COLUMN_NAMES)
it has 0 rows × n columns
, you need to create at least one row index by
df = pd.DataFrame(columns=COLUMN_NAMES, index=[0])
now it has 1 rows × n columns
. You are be able to add data. Otherwise its df that only consist colnames object(like a string list).
The cleanest way of iterating through a vector is via iterators:
for (auto it = begin (vector); it != end (vector); ++it) {
it->doSomething ();
}
or (equivalent to the above)
for (auto & element : vector) {
element.doSomething ();
}
Prior to C++0x, you have to replace auto by the iterator type and use member functions instead of global functions begin and end.
This probably is what you have seen. Compared to the approach you mention, the advantage is that you do not heavily depend on the type of vector
. If you change vector
to a different "collection-type" class, your code will probably still work. You can, however, do something similar in Java as well. There is not much difference conceptually; C++, however, uses templates to implement this (as compared to generics in Java); hence the approach will work for all types for which begin
and end
functions are defined, even for non-class types such as static arrays. See here: How does the range-based for work for plain arrays?
In older versions of express, we had to use:
app.use(express.bodyparser());
because body-parser was a middleware between node and express. Now we have to use it like:
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
This API has been available for a long time and enables to get access to market data (including live) if you are running a Bloomberg Terminal or have access to a Bloomberg Server, which is chargeable.
The only difference is that the API (not its code) has been open sourced, so it can now be used as a dependency in an open source project for example, without any copyrights issues, which was not the case before.
My few cents to previous excellent replies. the site www.sqlite.org works on a sqlite database. Here is the link when the author (Richard Hipp) replies to a similar question.
Button button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(this);
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v.getId() == R.id.button1){
Toast.makeText(context, "Button 1 Click", Toast.LENGTH_LONG).show();
}
}
Here's how you can put both batch code and the python one in single file:
0<0# : ^
'''
@echo off
echo batch code
python "%~f0" %*
exit /b 0
'''
print("python code")
the '''
respectively starts and ends python multi line comments.
0<0# : ^
is more interesting - due to redirection priority in batch it will be interpreted like :0<0# ^
by the batch script which is a label which execution will be not displayed on the screen. The caret at the end will escape the new line and second line will be attached to the first line.For python it will be 0<0
statement and a start of inline comment.

Using detach is magnitudes faster than any of the other answers here:
$('#mytable').find('tbody').detach();
Don't forget to put the tbody element back into the table since detach removed it:
$('#mytable').append($('<tbody>'));
Also note that when talking efficiency $(target).find(child)
syntax is faster than $(target > child)
. Why? Sizzle!

My answer is similar but different, there are a few ways to achieve toggling effect. I guess it depends on your circumstance. This may not be the best way for you in the end.
The missing piece you've been looking for is to create an if
statement. This allows for you to toggle your text.
JSFiddle: http://jsfiddle.net/8u2jF/
Javascript:
var status = "less";
function toggleText()
{
var text="Here is some text that I want added to the HTML file";
if (status == "less") {
document.getElementById("textArea").innerHTML=text;
document.getElementById("toggleButton").innerText = "See Less";
status = "more";
} else if (status == "more") {
document.getElementById("textArea").innerHTML = "";
document.getElementById("toggleButton").innerText = "See More";
status = "less"
}
}

The packages you installed introduced dependencies to version 5.2.3.0 dll's as user Bracher showed above. Microsoft.AspNet.WebApi.Cors is an example package. The path I take is to update the MVC project proir to any package installs:
Install-Package Microsoft.AspNet.Mvc -Version 5.2.3
I've always thought this was easier to learn with a detailed example, so here's how I think of makefiles. For each section you have one line that's not indented and it shows the name of the section followed by dependencies. The dependencies can be either other sections (which will be run before the current section) or files (which if updated will cause the current section to be run again next time you run make
).
Here's a quick example (keep in mind that I'm using 4 spaces where I should be using a tab, Stack Overflow won't let me use tabs):
a3driver: a3driver.o
g++ -o a3driver a3driver.o
a3driver.o: a3driver.cpp
g++ -c a3driver.cpp
When you type make
, it will choose the first section (a3driver). a3driver depends on a3driver.o, so it will go to that section. a3driver.o depends on a3driver.cpp, so it will only run if a3driver.cpp has changed since it was last run. Assuming it has (or has never been run), it will compile a3driver.cpp to a .o file, then go back to a3driver and compile the final executable.
Since there's only one file, it could even be reduced to:
a3driver: a3driver.cpp
g++ -o a3driver a3driver.cpp
The reason I showed the first example is that it shows the power of makefiles. If you need to compile another file, you can just add another section. Here's an example with a secondFile.cpp (which loads in a header named secondFile.h):
a3driver: a3driver.o secondFile.o
g++ -o a3driver a3driver.o secondFile.o
a3driver.o: a3driver.cpp
g++ -c a3driver.cpp
secondFile.o: secondFile.cpp secondFile.h
g++ -c secondFile.cpp
This way if you change something in secondFile.cpp or secondFile.h and recompile, it will only recompile secondFile.cpp (not a3driver.cpp). Or alternately, if you change something in a3driver.cpp, it won't recompile secondFile.cpp.
Let me know if you have any questions about it.
It's also traditional to include a section named "all" and a section named "clean". "all" will usually build all of the executables, and "clean" will remove "build artifacts" like .o files and the executables:
all: a3driver ;
clean:
# -f so this will succeed even if the files don't exist
rm -f a3driver a3driver.o
EDIT: I didn't notice you're on Windows. I think the only difference is changing the -o a3driver
to -o a3driver.exe

This answer explains the why behind this behavior.
Any approach to render the script
tag doesn't work as expected:
script
tag for external scriptsdangerouslySetInnerHTML
React DOM (the renderer for react on web) uses createElement
calls to render JSX into DOM elements.
createElement
uses the innerHTML
DOM API to finally add these to the DOM (see code in React source). innerHTML
does not execute script
tag added as a security consideration. And this is the reason why in turn rendering script
tags in React doesn't work as expected.
For how to use script
tags in React check some other answers on this page.

If you want to reload a ViewController initially loaded from a XIB, you can use the next UIViewController extension:
extension UIViewController {
func reloadViewFromNib() {
let parent = view.superview
view.removeFromSuperview()
view = nil
parent?.addSubview(view) // This line causes the view to be reloaded
}
}

var array =[2,3,1,9,8];
var minvalue = array[0];
for (var i = 0; i < array.length; i++) {
if(array[i]<minvalue)
{
minvalue = array[i];
}
}
console.log(minvalue);
If the function floatval does not work you can try to make this :
$string = "2968789218";
$float = $string * 1.0;
echo $float;
But for me all the previous answer worked ( try it in http://writecodeonline.com/php/ ) Maybe the problem is on your server ?
A node
is the generic name for any type of object in the DOM hierarchy. A node
could be one of the built-in DOM elements such as document
or document.body
, it could be an HTML tag specified in the HTML such as <input>
or <p>
or it could be a text node that is created by the system to hold a block of text inside another element. So, in a nutshell, a node
is any DOM object.
An element
is one specific type of node
as there are many other types of nodes (text nodes, comment nodes, document nodes, etc...).
The DOM consists of a hierarchy of nodes where each node can have a parent, a list of child nodes and a nextSibling and previousSibling. That structure forms a tree-like hierarchy. The document
node has the html
node as its child.
The html
node has its list of child nodes (the head
node and the body
node). The body
node would have its list of child nodes (the top level elements in your HTML page) and so on.
So, a nodeList
is simply an array-like list of nodes
.
An element is a specific type of node, one that can be directly specified in the HTML with an HTML tag and can have properties like an id
or a class
. can have children, etc... There are other types of nodes such as comment nodes, text nodes, etc... with different characteristics. Each node has a property .nodeType
which reports what type of node it is. You can see the various types of nodes here (diagram from MDN):
You can see an ELEMENT_NODE
is one particular type of node where the nodeType
property has a value of 1
.
So document.getElementById("test")
can only return one node and it's guaranteed to be an element (a specific type of node). Because of that it just returns the element rather than a list.
Since document.getElementsByClassName("para")
can return more than one object, the designers chose to return a nodeList
because that's the data type they created for a list of more than one node. Since these can only be elements (only elements typically have a class name), it's technically a nodeList
that only has nodes of type element in it and the designers could have made a differently named collection that was an elementList
, but they chose to use just one type of collection whether it had only elements in it or not.
EDIT: HTML5 defines an HTMLCollection
which is a list of HTML Elements (not any node, only Elements). A number of properties or methods in HTML5 now return an HTMLCollection
. While it is very similar in interface to a nodeList
, a distinction is now made in that it only contains Elements, not any type of node.
The distinction between a nodeList
and an HTMLCollection
has little impact on how you use one (as far as I can tell), but the designers of HTML5 have now made that distinction.
For example, the element.children
property returns a live HTMLCollection.
If you you want to copy a sub-set of the source table you can do:
INSERT INTO def (field_1, field_2, field3)
SELECT other_field_1, other_field_2, other_field_3 from `abc`
or to copy ALL fields from the source table to destination table you can do more simply:
INSERT INTO def
SELECT * from `abc`
In my case it was simple as using the Bind() method on the Configuration object. And then add the object as singleton in the DI.
var instructionSettings = new InstructionSettings();
Configuration.Bind("InstructionSettings", instructionSettings);
services.AddSingleton(typeof(IInstructionSettings), (serviceProvider) => instructionSettings);
The Instruction object can be as complex as you want.

In my case I need to simulate memory no longer being available so I did the following in the tool:
After 2 minutes my program could no longer allocate new memory and I was able to see how everything was handled.
Yes. Blat or any other self contained SMTP mailer. Blat is a fairly full featured SMTP client that runs from command line
Had the same issue.
I find out that react-scrips add "strict": true
to tsconfig.json
.
After I removed it everything works great.
Edit
Need to warn that changing this property means that you:
not being warned about potential run-time errors anymore.
as been pointed out by PaulG in comments! Thank you :)
Use "strict": false
only if you fully understand what it affects!
Gooye if it's possible to use Joda Time in your project then this code works for me:
String dateStr = "2012-10-01T09:45:00.000+02:00";
String customFormat = "yyyy-MM-dd HH:mm:ss";
DateTimeFormatter dtf = ISODateTimeFormat.dateTime();
LocalDateTime parsedDate = dtf.parseLocalDateTime(dateStr);
String dateWithCustomFormat = parsedDate.toString(DateTimeFormat.forPattern(customFormat));
System.out.println(dateWithCustomFormat);
width: '100%'
and alignSelf: 'stretch'
didn't work for me. Dimensions
didn't suite my task cause I needed to operate on a deeply nested view. Here's what worked for me, if I rewrite your code. I just added some more View
s and used flex
properties to achieve the needed layout:
{/* a column */}
<View style={styles.container}>
{/* some rows here */}
<Text style={styles.welcome}>
Welcome to React Natives
</Text>
{/* this row should take all available width */}
<View style={{ flexDirection: 'row' }}>
{/* flex 1 makes the view take all available width */}
<View style={{ flex: 1 }}>
<Text style={styles.line1}>
line1
</Text>
</View>
{/* I also had a button here, to the right of the text */}
</View>
{/* the rest of the rows */}
<Text style={styles.instructions}>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu

How about:
df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x
To do all these operations in one-liner:
setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))
#[1] name age gender
#<0 rows> (or 0-length row.names)
Or
data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))
I usually do like this:
from numpy import log as ln
Perhaps this can make you more comfortable.
When a new view is loaded in AngularJS
, Google Analytics does not count it as a new page load. Fortunately there is a way to manually tell GA to log a url as a new pageview.
_gaq.push(['_trackPageview', '<url>']);
would do the job, but how to bind that with AngularJS?
Here is a service which you could use:
(function(angular) {
angular.module('analytics', ['ng']).service('analytics', [
'$rootScope', '$window', '$location', function($rootScope, $window, $location) {
var track = function() {
$window._gaq.push(['_trackPageview', $location.path()]);
};
$rootScope.$on('$viewContentLoaded', track);
}
]);
}(window.angular));
When you define your angular module, include the analytics module like so:
angular.module('myappname', ['analytics']);
UPDATE:
You should use the new Universal Google Analytics tracking code with:
$window.ga('send', 'pageview', {page: $location.url()});
The HTTP_HOST
is obtained from the HTTP request header and this is what the client actually used as "target host" of the request. The SERVER_NAME
is defined in server config. Which one to use depends on what you need it for. You should now however realize that the one is a client-controlled value which may thus not be reliable for use in business logic and the other is a server-controlled value which is more reliable. You however need to ensure that the webserver in question has the SERVER_NAME
correctly configured. Taking Apache HTTPD as an example, here's an extract from its documentation:
If no
ServerName
is specified, then the server attempts to deduce the hostname by performing a reverse lookup on the IP address. If no port is specified in theServerName
, then the server will use the port from the incoming request. For optimal reliability and predictability, you should specify an explicit hostname and port using theServerName
directive.
Update: after checking the answer of Pekka on your question which contains a link to bobince's answer that PHP would always return HTTP_HOST
's value for SERVER_NAME
, which goes against my own PHP 4.x + Apache HTTPD 1.2.x experiences from a couple of years ago, I blew some dust from my current XAMPP environment on Windows XP (Apache HTTPD 2.2.1 with PHP 5.2.8), started it, created a PHP page which prints the both values, created a Java test application using URLConnection
to modify the Host
header and tests taught me that this is indeed (incorrectly) the case.
After first suspecting PHP and digging in some PHP bug reports regarding the subject, I learned that the root of the problem is in web server used, that it incorrectly returned HTTP Host
header when SERVER_NAME
was requested. So I dug into Apache HTTPD bug reports using various keywords regarding the subject and I finally found a related bug. This behaviour was introduced since around Apache HTTPD 1.3. You need to set UseCanonicalName
directive to on
in the <VirtualHost>
entry of the ServerName
in httpd.conf
(also check the warning at the bottom of the document!).
<VirtualHost *>
ServerName example.com
UseCanonicalName on
</VirtualHost>
This worked for me.
Summarized, SERVER_NAME
is more reliable, but you're dependent on the server config!
Faster solution:
private boolean isPackageInstalled(String packagename, PackageManager packageManager) {
try {
packageManager.getPackageGids(packagename);
return true;
} catch (NameNotFoundException e) {
return false;
}
}
getPackageGids
is less expensive from getPackageInfo
, so it work faster.
Run 10000 on API 15
Exists pkg:
getPackageInfo: nanoTime = 930000000
getPackageGids: nanoTime = 350000000

getPackageGids: nanoTime = 380000000

getPackageGids: nanoTime = 3117544269
Note: This will not work in some virtual spaces. They can violate the Android API and always return an array, even if there is no application with that package name.
In this case, use getPackageInfo
.
Its very simple. Call one function inside another function with parameters.
function fun1()
{
var a=10;
var b=20;
fun2(a,b); //calling function fun2() and passing 2 parameters
}
function fun2(num1,num2)
{
var sum;
sum = num1+num2;
return sum;
}
fun1(); //trigger function fun1
I have released a package called python-drawnow that provides functionality to let a figure update, typically called within a for loop, similar to Matlab's drawnow
.
An example usage:
from pylab import figure, plot, ion, linspace, arange, sin, pi
def draw_fig():
# can be arbitrarily complex; just to draw a figure
#figure() # don't call!
plot(t, x)
#show() # don't call!
N = 1e3
figure() # call here instead!
ion() # enable interactivity
t = linspace(0, 2*pi, num=N)
for i in arange(100):
x = sin(2 * pi * i**2 * t / 100.0)
drawnow(draw_fig)
This package works with any matplotlib figure and provides options to wait after each figure update or drop into the debugger.
Apache Cayanne ORM has an "In memory evaluation"
It may not work for unmapped object, but looks promising:
Expression exp = ExpressionFactory.likeExp("artistName", "A%");
List startWithA = exp.filterObjects(artists);
Even though utf8_decode
is a useful solution, I prefer to correct the encoding errors on the table itself. In my opinion it is better to correct the bad characters themselves than making "hacks" in the code. Simply do a replace
on the field on the table. To correct the bad encoded characters from OP :
update <table> set <field> = replace(<field>, "ë", "ë")
update <table> set <field> = replace(<field>, "Ã", "à")
update <table> set <field> = replace(<field>, "ì", "ì")
update <table> set <field> = replace(<field>, "ù", "ù")
Where <table>
is the name of the mysql table and <field>
is the name of the column in the table. Here is a very good check-list for those typically bad encoded windows-1252 to utf-8 characters -> Debugging Chart Mapping Windows-1252 Characters to UTF-8 Bytes to Latin-1 Characters.
Remember to backup your table before trying to replace any characters with SQL!
[I know this is an answer to a very old question, but was facing the issue once again. Some old windows machine didnt encoded the text correct before inserting it to the utf8_general_ci collated table.]

The alert()
dialog is not rendered in HTML, and thus the HTML you have embedded is meaningless.
You'd need to use a custom modal to achieve that.
If you have supporting indexes, and relatively high counts, something like this may be considerably faster than the solutions suggested:
SELECT name, MAX(Rcount) + MAX(Acount) AS TotalCount
FROM (
SELECT name, COUNT(*) AS Rcount, 0 AS Acount
FROM Results GROUP BY name
UNION ALL
SELECT name, 0, count(*)
FROM Archive_Results
GROUP BY name
) AS Both
GROUP BY name
ORDER BY name;
You might need a GLOBAL TEMPORARY TABLE.
In Oracle these are created once and then when invoked the data is private to your session.
Try something like this...
CREATE GLOBAL TEMPORARY TABLE temp_number
( number_column NUMBER( 10, 0 )
)
ON COMMIT DELETE ROWS;
BEGIN
INSERT INTO temp_number
( number_column )
( select distinct sgbstdn_pidm
from sgbstdn
where sgbstdn_majr_code_1 = 'HS04'
and sgbstdn_program_1 = 'HSCOMPH'
);
FOR pidms_rec IN ( SELECT number_column FROM temp_number )
LOOP
-- Do something here
NULL;
END LOOP;
END;

Create a function like so:
CREATE FUNCTION dbo.fn_FileExists(@path varchar(512))
RETURNS BIT
AS
BEGIN
DECLARE @result INT
EXEC master.dbo.xp_fileexist @path, @result OUTPUT
RETURN cast(@result as bit)
END;
GO
Edit your table and add a computed column (IsExists BIT). Set the expression to:
dbo.fn_FileExists(filepath)
Then just select:
SELECT * FROM dbo.MyTable where IsExists = 1
Update:
To use the function outside a computed column:
select id, filename, dbo.fn_FileExists(filename) as IsExists
from dbo.MyTable
Update:
If the function returns 0 for a known file, then there is likely a permissions issue. Make sure the SQL Server's account has sufficient permissions to access the folder and files. Read-only should be enough.
And YES, by default, the 'NETWORK SERVICE' account will not have sufficient right into most folders. Right click on the folder in question and select 'Properties', then click on the 'Security' tab. Click 'Edit' and add 'Network Service'. Click 'Apply' and retest.
It seems that you are trying to get 5 items out of a collection with 5 items. Looking at your code, it seems you're starting at the second value in your collection at position 1. Collections are zero-based, so you should start with the item at index 0. Try this:
TextBox box1 = (TextBox)Gridview1.Rows[i].Cells[0].FindControl("txt_type");
TextBox box2 = (TextBox)Gridview1.Rows[i].Cells[1].FindControl("txt_total");
TextBox box3 = (TextBox)Gridview1.Rows[i].Cells[2].FindControl("txt_max");
TextBox box4 = (TextBox)Gridview1.Rows[i].Cells[3].FindControl("txt_min");
TextBox box5 = (TextBox)Gridview1.Rows[i].Cells[4].FindControl("txt_rate");
Primitive Data Types :
Reference/Object Data Types :
I've combined both solutions from @jps to one function:
jQuery.fn.getEvents = function() {
if (typeof(jQuery._data) === 'function') {
return jQuery._data(this.get(0), 'events') || {};
}
// jQuery version < 1.7.?
if (typeof(this.data) === 'function') {
return this.data('events') || {};
}
return {};
};
But beware, this function can only return events that were set using jQuery itself.
I recently wrote on this topic, though this post it old, I thought it will be helpful to someone who wants to know how to implement BaseAdapter.notifyDataSetChanged()
step by step and in a correct way.
Please follow How to correctly implement BaseAdapter.notifyDataSetChanged() in Android or the newer blog BaseAdapter.notifyDataSetChanged().
RxJS Operators are functions that build on the observables foundation to enable sophisticated manipulation of collections.
For example, RxJS defines operators such as map()
, filter()
, concat()
, and flatMap()
.
You can use pipes to link operators together. Pipes let you combine multiple functions into a single function.
The pipe()
function takes as its arguments the functions you want to combine, and returns a new function that, when executed, runs the composed functions in sequence.
do like this :
child{
position:absolute;
margin: auto;
top: 0;
bottom: 0;
left: 0;
right: 0;
}
The question has not been completely answered, IMHO. I will try to explain: I have a crontab entry that schedules a bash shell command procedure, that in turn does some cleanup of my files; and, when done, sends a notification to me using the OS X notification center (with the command osascript -e 'display notification ...
). If someone (e.g. my wife or my daughter) switches the current user of the computer to her, leaving me in the background, the cron script fails when sending the notification.
So, Who is the current user means Has some other people become the effective user leaving me in the background? Do stat -f "%Su" /dev/console
returns the current active user name?
The answer is yes; so, now my crontab shell script has been modified in the following way:
...
if [ "$(/usr/bin/stat -f ""%Su"" /dev/console)" = "loreti" ]
then /usr/bin/osascript -e \
'display notification "Cleanup done" sound name "sosumi" with title "myCleanup"'
fi
define() is part of the AMD spec of js
See:
Edit: Also see Claudio's answer below. Likely the more relevant explanation.
Lodash is also the same First write a script as follows:
<script type="text/template" id="genTable">
<table cellspacing='0' cellpadding='0' border='1'>
<tr>
<% for(var prop in users[0]){%>
<th><%= prop %> </th>
<% }%>
</tr>
<%_.forEach(users, function(user) { %>
<tr>
<% for(var prop in user){%>
<td><%= user[prop] %> </td>
<% }%>
</tr>
<%})%>
</table>
Now write some simple JS as follows:
var arrOfObjects = [];
for (var s = 0; s < 10; s++) {
var simpleObject = {};
simpleObject.Name = "Name_" + s;
simpleObject.Address = "Address_" + s;
arrOfObjects[s] = simpleObject;
}
var theObject = { 'users': arrOfObjects }
var compiled = _.template($("#genTable").text());
var sigma = compiled({ 'users': myArr });
$(sigma).appendTo("#popup");
Where popoup is a div where you want to generate the table
inspect.trace will let you get local variables after an exception has been thrown. You can then wrap the unit tests with a decorator like the following one to save off those local variables for examination during the post mortem.
import random
import unittest
import inspect
def store_result(f):
"""
Store the results of a test
On success, store the return value.
On failure, store the local variables where the exception was thrown.
"""
def wrapped(self):
if 'results' not in self.__dict__:
self.results = {}
# If a test throws an exception, store local variables in results:
try:
result = f(self)
except Exception as e:
self.results[f.__name__] = {'success':False, 'locals':inspect.trace()[-1][0].f_locals}
raise e
self.results[f.__name__] = {'success':True, 'result':result}
return result
return wrapped
def suite_results(suite):
"""
Get all the results from a test suite
"""
ans = {}
for test in suite:
if 'results' in test.__dict__:
ans.update(test.results)
return ans
# Example:
class TestSequenceFunctions(unittest.TestCase):
def setUp(self):
self.seq = range(10)
@store_result
def test_shuffle(self):
# make sure the shuffled sequence does not lose any elements
random.shuffle(self.seq)
self.seq.sort()
self.assertEqual(self.seq, range(10))
# should raise an exception for an immutable sequence
self.assertRaises(TypeError, random.shuffle, (1,2,3))
return {1:2}
@store_result
def test_choice(self):
element = random.choice(self.seq)
self.assertTrue(element in self.seq)
return {7:2}
@store_result
def test_sample(self):
x = 799
with self.assertRaises(ValueError):
random.sample(self.seq, 20)
for element in random.sample(self.seq, 5):
self.assertTrue(element in self.seq)
return {1:99999}
suite = unittest.TestLoader().loadTestsFromTestCase(TestSequenceFunctions)
unittest.TextTestRunner(verbosity=2).run(suite)
from pprint import pprint
pprint(suite_results(suite))
The last line will print the returned values where the test succeeded and the local variables, in this case x, when it fails:
{'test_choice': {'result': {7: 2}, 'success': True},
'test_sample': {'locals': {'self': <__main__.TestSequenceFunctions testMethod=test_sample>,
'x': 799},
'success': False},
'test_shuffle': {'result': {1: 2}, 'success': True}}
Har det gøy :-)
Assuming t1 is the folder with files in it, and t2 is the empty directory. What you want is something like this:
sudo cp -R t1/* t2/
Bear in mind, for the first example, t1 and t2 have to be the full paths, or relative paths (based on where you are). If you want, you can navigate to the empty folder (t2) and do this:
sudo cp -R t1/* ./
Or you can navigate to the folder with files (t1) and do this:
sudo cp -R ./* t2/
Note: The * sign (or wildcard) stands for all files and folders. The -R flag means recursively (everything inside everything).
This will get the country code set for the phone (phones language, NOT user location):
String locale = context.getResources().getConfiguration().locale.getCountry();
can also replace getCountry() with getISO3Country() to get a 3 letter ISO code for the country. This will get the country name:
String locale = context.getResources().getConfiguration().locale.getDisplayCountry();
This seems easier than the other methods and rely upon the localisation settings on the phone, so if a US user is abroad they probably still want Fahrenheit and this will work :)
Editors note: This solution has nothing to do with the location of the phone. It is constant. When you travel to Germany locale will NOT change. In short: locale != location.
Using regedit, remove the entries corresponding to java 7. It will work.
A quick way to do it is by:
public boolean isStringAlpha(String aString) {
int charCount = 0;
String alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
if (aString.length() == 0) {
return false; //zero length string ain't alpha
}
for (int i = 0; i < aString.length(); i++) {
for (int j = 0; j < alphabet.length(); j++) {
if (aString.substring(i, i + 1).equals(alphabet.substring(j, j + 1))
|| aString.substring(i, i + 1).equals(alphabet.substring(j, j + 1).toLowerCase())) {
charCount++;
}
}
if (charCount != (i + 1)) {
System.out.println("\n**Invalid input! Enter alpha values**\n");
return false;
}
}
return true;
}
Because you don't have to run the whole aString
to check if it isn't an alpha String.
This is impossible as a child's z-index
is set to the same stacking index as its parent.
You have already solved the problem by removing the z-index from the parent, keep it like this or make the element a sibling instead of a child.
It's a syntax for array references - you need to use (&array)
to clarify to the compiler that you want a reference to an array, rather than the (invalid) array of references int & array[100];
.
EDIT: Some clarification.
void foo(int * x);
void foo(int x[100]);
void foo(int x[]);
These three are different ways of declaring the same function. They're all treated as taking an int *
parameter, you can pass any size array to them.
void foo(int (&x)[100]);
This only accepts arrays of 100 integers. You can safely use sizeof
on x
void foo(int & x[100]); // error
This is parsed as an "array of references" - which isn't legal.

Blob is much slower than String.fromCharCode(null,array);
but that fails if the array buffer gets too big. The best solution I have found is to use String.fromCharCode(null,array);
and split it up into operations that won't blow the stack, but are faster than a single char at a time.
The best solution for large array buffer is:
function arrayBufferToString(buffer){
var bufView = new Uint16Array(buffer);
var length = bufView.length;
var result = '';
var addition = Math.pow(2,16)-1;
for(var i = 0;i<length;i+=addition){
if(i + addition > length){

I found this to be about 20 times faster than using blob. It also works for large strings of over 100mb.
Deprecated answer (Spring Data JPA <=1.6.x):
@Modifying
annotation to the rescue. You will need to provide your custom SQL behaviour though.
public interface UserRepository extends JpaRepository<User, Long> {
@Modifying
@Query("delete from User u where u.firstName = ?1")
void deleteUsersByFirstName(String firstName);
}
Update:
In modern versions of Spring Data JPA (>=1.7.x) query derivation for delete
, remove
and count
operations is accessible.
public interface UserRepository extends CrudRepository<User, Long> {
Long countByFirstName(String firstName);
Long deleteByFirstName(String firstName);
List<User> removeByFirstName(String firstName);
}
I recommend you to use Attesoro (http://attesoro.org/). Is simple and easy to use. And is made in java.
Export it into some text format. The easiest will probably be a tab-delimited version, but CSV can work as well.
Use the load data capability. See http://dev.mysql.com/doc/refman/5.1/en/load-data.html
Look half way down the page, as it will gives a good example for tab separated data:
FIELDS TERMINATED BY '\t' ENCLOSED BY '' ESCAPED BY '\'
Check your data. Sometimes quoting or escaping has problems, and you need to adjust your source, import command-- or it may just be easier to post-process via SQL.
key($arr);
will return the key value for the current array element
If you sometimes run different versions of your application, make sure you delete 'Bla' from the application bin directory if the version running doesn't need it.
In C++/CLI, a handle is a pointer to an object located on the GC heap. Creating an object on the (unmanaged) C++ heap is achieved using new
and the result of a new
expression is a "normal" pointer. A managed object is allocated on the GC (managed) heap with a gcnew
expression. The result will be a handle. You can't do pointer arithmetic on handles. You don't free handles. The GC will take care of them. Also, the GC is free to relocate objects on the managed heap and update the handles to point to the new locations while the program is running.
Your ProcExit label is your place where you release all the resources whether an error happened or not. For instance:
Public Sub SubA()
On Error Goto ProcError
Connection.Open
Open File for Writing
SomePreciousResource.GrabIt
ProcExit:
Connection.Close
Connection = Nothing
Close File
SomePreciousResource.Release
Exit Sub
ProcError:
MsgBox Err.Description
Resume ProcExit
End Sub
First, I see you're using an explicit $.parseJSON()
. If that's because you're manually serializing JSON on the server-side, don't. ASP.NET will automatically JSON-serialize your method's return value and jQuery will automatically deserialize it for you too.
To iterate through the first item in the array you've got there, use code like this:
var firstItem = response.d[0];
for(key in firstItem) {
console.log(key + ':' + firstItem[key]);
}
If there's more than one item (it's hard to tell from that screenshot), then you can loop over response.d
and then use this code inside that outer loop.
I had an identical problem, which I solved by restarting my Python editor and shell. I had installed pywin32
but the new modules were not picked up until the restarts.
If you've already done that, do a search in your Python installation for win32api
and you should find win32api.pyd
under ${PYTHON_HOME}\Lib\site-packages\win32
.
This is a complete solution. I've just updated this example code with the information provided in the answer below by @mad. Also check the solution below from @Khobaib explaining how to deal with picasa images.
I've just reviewed my original answer and created a simple Android Studio project you can checkout from github and import directly on your system.
https://github.com/hanscappelle/SO-2169649
(note that the multiple file selection still needs work)
With support for images from file explorers thanks to user mad.
public class BrowsePictureActivity extends Activity {
// this is the action code we use in our intent,
// this way we know we're looking at the response from our own action
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
findViewById(R.id.Button01)
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
}
}
}
/**
* helper to retrieve the path of an image URI
*/
public String getPath(Uri uri) {
// just some safety built in
if( uri == null ) {
// TODO perform some logging or show user feedback
return null;
}
// try to retrieve the image from the media store first
// this will only work for images selected from gallery
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if( cursor != null ){
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String path = cursor.getString(column_index);
cursor.close();
return path;
}
// this is our fallback here
return uri.getPath();
}
}
Since someone requested that information in a comment and it's better to have information gathered.
Set an extra parameter EXTRA_ALLOW_MULTIPLE
on the intent:
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
And in the Result handling check for that parameter:
if (Intent.ACTION_SEND_MULTIPLE.equals(data.getAction()))
&& Intent.hasExtra(Intent.EXTRA_STREAM)) {
// retrieve a collection of selected images
ArrayList<Parcelable> list = intent.getParcelableArrayListExtra(Intent.EXTRA_STREAM);
// iterate over these images
if( list != null ) {
for (Parcelable parcel : list) {
Uri uri = (Uri) parcel;
// TODO handle the images one by one here
}
}
}
Note that this is only supported by API level 18+.

%>%
has no builtin meaning but the user (or a package) is free to define operators of the form %whatever%
in any way they like. For example, this function will return a string consisting of its left argument followed by a comma and space and then it's right argument.
"%,%" <- function(x, y) paste0(x, ", ", y)
# test run
"Hello" %,% "World"
## [1] "Hello, World"
The base of R provides %*%
(matrix mulitiplication), %/%
(integer division), %in%
(is lhs a component of the rhs?), %o%
(outer product) and %x%
(kronecker product). It is not clear whether %%
falls in this category or not but it represents modulo.
expm The R package, expm, defines a matrix power operator %^%
. For an example see Matrix power in R .
operators The operators R package has defined a large number of such operators such as %!in%
(for not %in%
). See http://cran.r-project.org/web/packages/operators/operators.pdf
igraph This package defines %--% , %->% and %<-% to select edges.
lubridate This package defines %m+% and %m-% to add and subtract months and %--% to define an interval. igraph also defines %--% .
magrittr In the case of %>%
the magrittr R package has defined it as discussed in the magrittr vignette. See http://cran.r-project.org/web/packages/magrittr/vignettes/magrittr.html
magittr has also defined a number of other such operators too. See the Additional Pipe Operators section of the prior link which discusses %T>%
, %<>%
and %$%
and http://cran.r-project.org/web/packages/magrittr/magrittr.pdf for even more details.
dplyr The dplyr R package used to define a %.%
operator which is similar; however, it has been deprecated and dplyr now recommends that users use %>%
which dplyr imports from magrittr and makes available to the dplyr user. As David Arenburg has mentioned in the comments this SO question discusses the differences between it and magrittr's %>%
: Differences between %.% (dplyr) and %>% (magrittr)
pipeR The R package, pipeR, defines a %>>%
operator that is similar to magrittr's %>% and can be used as an alternative to it. See http://renkun.me/pipeR-tutorial/
The pipeR package also has defined a number of other such operators too. See: http://cran.r-project.org/web/packages/pipeR/pipeR.pdf
postlogic The postlogic package defined %if%
and %unless%
operators.
wrapr The R package, wrapr, defines a dot pipe %.>%
that is an explicit version of %>%
in that it does not do implicit insertion of arguments but only substitutes explicit uses of dot on the right hand side. This can be considered as another alternative to %>%
. See https://winvector.github.io/wrapr/articles/dot_pipe.html
Bizarro pipe. This is not really a pipe but rather some clever base syntax to work in a way similar to pipes without actually using pipes. It is discussed in http://www.win-vector.com/blog/2017/01/using-the-bizarro-pipe-to-debug-magrittr-pipelines-in-r/ The idea is that instead of writing:
1:8 %>% sum %>% sqrt
## [1] 6
one writes the following. In this case we explicitly use dot rather than eliding the dot argument and end each component of the pipeline with an assignment to the variable whose name is dot (.
) . We follow that with a semicolon.
1:8 ->.; sum(.) ->.; sqrt(.)
## [1] 6
Update Added info on expm package and simplified example at top. Added postlogic package.
add {3,5}
to your expression which means length between 3 to 5
/^([a-zA-Z0-9_-]){3,5}$/
This one disables all bogus verbs and only allows GET and POST
<system.webServer>
<security>
<requestFiltering>
<verbs allowUnlisted="false">
<clear/>
<add verb="GET" allowed="true"/>
<add verb="POST" allowed="true"/>
</verbs>
</requestFiltering>
</security>
</system.webServer>
Another addition for those who need it. Ash Clarke's solution does not work if they are using different protocols so be sure that if you are using SSL, your iframe is using SSL as well or it will break the function. His solution did work for the domains itself though, so thanks for that.
I come across similar problem while calling stored procedure

Which dynamically constructing the query for search I was calling above one by:

I hope this will be helpfull to someone who fall in similar trap.
In Django this is trivial (and actually works, I had issues with a number of the solutions not correctly returning negatives for latitude).
For instance, let's say you are using django-geopostcodes (of which I am the author).
from django.contrib.gis.geos import MultiPoint
from django.contrib.gis.db.models.functions import Distance
from django_geopostcodes.models import Locality
qs = Locality.objects.anything_icontains('New York')
points = [locality.point for locality in qs]
multipoint = MultiPoint(*points)
point = multipoint.centroid
point
is a Django Point
instance that can then be used to do things such as retrieve all objects that are within 10km of that centre point;
Locality.objects.filter(point__distance_lte=(point, D(km=10)))\
.annotate(distance=Distance('point', point))\
.order_by('distance')
Changing this to raw Python is trivial;
from django.contrib.gis.geos import Point, MultiPoint
points = [
Point((145.137075, -37.639981)),
Point((144.137075, -39.639981)),
]
multipoint = MultiPoint(*points)
point = multipoint.centroid
Under the hood Django is using GEOS - more details at https://docs.djangoproject.com/en/1.10/ref/contrib/gis/geos/
The benefit of WireShark is that it could possibly show you errors in levels below the HTTP protocol. Fiddler will show you errors in the HTTP protocol.
If you think the problem is somewhere in the HTTP request issued by the browser, or you are just looking for more information in regards to what the server is responding with, or how long it is taking to respond, Fiddler should do.
If you suspect something may be wrong in the TCP/IP protocol used by your browser and the server (or in other layers below that), go with WireShark.
v1.42 is adding some nice refinements to how folds look and function. See https://github.com/microsoft/vscode-docs/blob/vnext/release-notes/v1_42.md#folded-range-highlighting:
Folded Range Highlighting
Folded ranges now are easier to discover thanks to a background color for all folded ranges.
Fold highlight color Theme: Dark+
The feature is controled by the setting editor.foldingHighlight and the color can be customized with the color editor.foldBackground.
"workbench.colorCustomizations": { "editor.foldBackground": "#355000" }
Folding Refinements
Shift + Click
on the folding indicator first only folds the inner ranges.Shift + Click
again (when all inner ranges are already folded) will also fold the parent.Shift + Click
again unfolds all.
When using the Fold command (kb(
editor.fold
))] on an already folded range, the next unfolded parent range will be folded.

I faced similar issue, with RelativeLayout as the root element for each row in the recyclerview.
To solve the issue, find the xml file that holds each row and make sure that the root element's height is wrap_content
NOT match_parent
.
Douglas Crockford, the author of jslint has written (and spoken) about this issue many times. There's a section on this page of his website which covers this:
for Statement
A for class of statements should have the following form:
for (initialization; condition; update) { statements } for (variable in object) { if (filter) { statements } }
The first form should be used with arrays and with loops of a predeterminable number of iterations.
The second form should be used with objects. Be aware that members that are added to the prototype of the object will be included in the enumeration. It is wise to program defensively by using the hasOwnProperty method to distinguish the true members of the object:
for (variable in object) { if (object.hasOwnProperty(variable)) { statements } }
Crockford also has a video series on YUI theater where he talks about this. Crockford's series of videos/talks about javascript are a must see if you're even slightly serious about javascript.
DISTINCT
removes rows if all selected values are equal. Apparently, you have entries with the same p.id
but with different pl.nm
(or pl.val
or pl.txt_val
). The answer to your question depends on which one of these values you want to show in the one row with your p.id
(the first? the smallest? any?).
There are some webkit css properties that should work on Chrome/Safari at least:
-webkit-text-stroke-width: 2px;
-webkit-text-stroke-color: black;
That's a 2px wide black text outline.
I was going to try something like this:
[Range(typeof(decimal), ((double)0).ToString(), ((double)decimal.MaxValue).ToString(), ErrorMessage = "Amount must be greater than or equal to zero.")]
The problem with doing this, though, is that the compiler wants a constant expression, which disallows ((double)0).ToString()
. The compiler will take
[Range(0d, (double)decimal.MaxValue, ErrorMessage = "Amount must be greater than zero.")]
But how does this handle language specific sorting rules? Does it take locale into account?
No, list.sort()
is a generic sorting function. If you want to sort according to the Unicode rules, you'll have to define a custom sort key function. You can try using the pyuca module, but I don't know how complete it is.
The easiest way is to use to_datetime
:
df['col'] = pd.to_datetime(df['col'])
It also offers a dayfirst
argument for European times (but beware this isn't strict).
Here it is in action:
In [11]: pd.to_datetime(pd.Series(['05/23/2005']))
Out[11]:
0 2005-05-23 00:00:00
dtype: datetime64[ns]
You can pass a specific format:
In [12]: pd.to_datetime(pd.Series(['05/23/2005']), format="%m/%d/%Y")
Out[12]:
0 2005-05-23
dtype: datetime64[ns]

You need to use HAVING
, not WHERE
.
The difference is: the WHERE
clause filters which rows MySQL selects. Then MySQL groups the rows together and aggregates the numbers for your COUNT
function.
HAVING
is like WHERE
, only it happens after the COUNT
value has been computed, so it'll work as you expect. Rewrite your subquery as:
( -- where that pid is in the set:
SELECT c2.pid -- of pids
FROM Catalog AS c2 -- from catalog
WHERE c2.pid = c1.pid
HAVING COUNT(c2.sid) >= 2)
You could use the INDIRECT function. This takes a string and converts it into a range
More info here
=INDIRECT("K"&A2)
But it's preferable to use INDEX as it is less volatile.
=INDEX(K:K,A2)
This returns a value or the reference to a value from within a table or range
More info here
Put either function into cell B2 and fill down.
You assign to big and small before the array is initialized, i.e., big and small assume the value of whatever is on the stack at this point. As they are just plain value types and no references, they won't assume a new value once values[0] is written to via cin >>.
Just move the assignment after your first loop and it should be fine.
import pandas as pd
pd.options.display.float_format = '${:,.2f}'.format
df = pd.DataFrame([123.4567, 234.5678, 345.6789, 456.7890],
index=['foo','bar','baz','quux'],
columns=['cost'])
print(df)
yields
cost
foo $123.46
bar $234.57
baz $345.68
quux $456.79
but this only works if you want every float to be formatted with a dollar sign.
Otherwise, if you want dollar formatting for some floats only, then I think you'll have to pre-modify the dataframe (converting those floats to strings):
import pandas as pd
df = pd.DataFrame([123.4567, 234.5678, 345.6789, 456.7890],
index=['foo','bar','baz','quux'],
columns=['cost'])
df['foo'] = df['cost']
df['cost'] = df['cost'].map('${:,.2f}'.format)
print(df)
yields
cost foo
foo $123.46 123.4567
bar $234.57 234.5678
baz $345.68 345.6789
quux $456.79 456.7890

In addition to standard net/http package, you can consider using my GoRequest which wraps around net/http and make your life easier without thinking too much about json or struct. But you can also mix and match both of them in one request! (you can see more details about it in gorequest github page)
So, in the end your code will become like follow:
func main() {
url := "http://restapi3.apiary.io/notes"
fmt.Println("URL:>", url)
request := gorequest.New()
titleList := []string{"title1", "title2", "title3"}
for _, title := range titleList {
resp, body, errs := request.Post(url).
Set("X-Custom-Header", "myvalue").
Send(`{"title":"` + title + `"}`).
End()

This depends on how you want to achieve. I made this library because I have the same problem with you and I want code that is shorter, easy to use with json, and more maintainable in my codebase and production system.
I had this error
(Illuminate\Contracts\Container\BindingResolutionException Target class [App\Http\Controllers\ControllerFileName] does not exist.
Solution: just check your class Name, it should be the exact same of your file name.
If you need a drive letter (some applications don't like UNC style paths that start with a machine-name) you can "map a drive" to a UNC path. Right-click on "My Computer" and select Map Network Drive... or use this command line:
NET USE z: \server\c$\folder1\folder2
NET USE y: \server\d$
Note that you can map drive-to-drive or drill down and map to sub-folder.
You can use this (or any variant):
Files.copy(src, dst, StandardCopyOption.REPLACE_EXISTING);
Also, I'd recommend using File.separator
or /
instead of \\
to make it compliant across multiple OS, question/answer on this available here.
Since you're not sure how to temporarily store files, take a look at ArrayList
:
List<File> files = new ArrayList();
files.add(foundFile);
To move a List
of files into a single directory:
List<File> files = ...;
String path = "C:/destination/";
for(File file : files) {
Files.copy(file.toPath(),
(new File(path + file.getName())).toPath(),
StandardCopyOption.REPLACE_EXISTING);
}
Here's my example in which I work
Marquee (<marquee>
) is a deprecated and not a valid HTML tag. You can use many jQuery plugins to do. One of it, is jQuery News Ticker. There are many more!
Use:
List<Person> pList = new List<Person>();
/* Fill list */
var result = pList.Where(p => p.Name != null).GroupBy(p => p.Id).Select(grp => grp.FirstOrDefault());
The where
helps you filter the entries (could be more complex) and the groupby
and select
perform the distinct function.
This error can be due to many many things.
The key here seems the hint about error reading
. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.
You could also try with sudo
, that might solve a permission problem if that's the case.
Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...
check if your field with the primary key is set to auto increment
I had the same problem and, in my case, the problem was that python was looking for packages in some ordered locations, first of all the default computer one where default old packages are.
To check what your python is looking for you can do:
>>> import sys
>>> print '\n'.join(sys.path)
This was outputting the directory '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python' before pip or brew or port folders.
The simple solution is:
export PYTHONPATH="/Library/Python/2.7/site-packages:$PYTHONPATH"
This worked well for me, I advise you to add this line to your home bash_profile file for the next time. Remember that sys.path is built using the current working directory, followed by the directories in the PYTHONPATH environment variable. Then there are the installation-dependent default dirs.
Another way is to handle the CellContentClick event (which doesn't give you the current value in the cell's Value property), call grid.CommitEdit(DataGridViewDataErrorContexts.Commit) to update the value which in turn will fire CellValueChanged where you can then get the actual (i.e. correct) DataGridViewCheckBoxColumn value.
private void grid_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
grid.CommitEdit(DataGridViewDataErrorContexts.Commit);
}
private void grid_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
// do something with grid.Rows[e.RowIndex].Cells[e.ColumnIndex].Value
}

findViewById also can return null if you're inside a Fragment. As described here: findViewById in Fragment
You should call getView() to return the top level View inside a Fragment. Then you can find the layout items (buttons, textviews, etc)
Googling on topic always brings me to this SO question so here is working mysql code that deletes BOTH tables and views:

When running into this error and reviewing my dataset which appeared to have no missing data, I discovered that a few of my entries had the special character "#" which derailed importing the data. Once I removed the "#" from the offending cells, the data imported without issue.
This worked for me: Add compile 'com.android.support:appcompat-v7:21.0.3' to the gradle. Change the sdk target to 21. Hope it works for you!
use this actiion
$(document).ready(function () {
var a = this.id;
alert (a);
});
@Html.ActionLink("Edit","ActionName",new{id=item.id},new{onclick="functionname();"})
Like the other examples,
I use a similar approach but instead of spending time calculating out the last output length, etc,
I simply use ANSI code escapes to move back to the beginning of the line and then clear that entire line before printing my current status output.
import sys
class Printer():
"""Print things to stdout on one line dynamically"""
def __init__(self,data):
sys.stdout.write("\r\x1b[K"+data.__str__())
sys.stdout.flush()
To use in your iteration loop you would just call something like:
x = 1
for f in fileList:
ProcessFile(f)
output = "File number %d completed." % x
Printer(output)
x += 1
I will prefer to use findIndex()
method:
var index = myArray.findIndex('hello','stevie');
index
will give you the index number.
Also you can try this, if you want to focus on same text after error.
If you wants to show this error message in a paragraph then you can use this one:
$(document).ready(function () {
$("#submit").click(function () {
if($('#selBooks').val() === '') {
$("#Paragraph_id").text("Please select a book and then proceed.").show();
$('#selBooks').focus();
return false;
}
});
});
Any custom file extension can be associated with standard syntax highlighting with
custom files association
in User Settings as follows.
Note that this will be a permanent setting. In order to set for the current session alone, type in the preferred language in
Select Language Mode
box (without changingfile association
settings)
If the required syntax package is not available by default, you can add them via the Extension Marketplace (Ctrl+Shift+X) and search for the language package.
You can further reproduce the above steps to map the file extensions with the new syntax package.
There are differences between foreach

.
A very good description you can find here: MS-ScriptingGuy
For testing in PS, here you have scripts to show the difference.

1..10 | ForEach-Object {
if ($_ -eq 5) {return}
# if ($_ -ge 5) {return} # Omit from 5.

}
write-host "after1"
# Cancels whole script at 15, "after2" not printed.
11..20 | ForEach-Object {
if ($_ -eq 15) {continue}
Write-Host $_
}
write-host "after2"
# Cancels whole script at 25, "after3" not printed.
21..30 | ForEach-Object {
if ($_ -eq 25) {break}
Write-Host $_

Yes, something like this:
SELECT
id,
action_heading,
CASE
WHEN action_type = 'Income' THEN action_amount
ELSE NULL
END AS income_amt,
CASE
WHEN action_type = 'Expense' THEN action_amount
ELSE NULL
END AS expense_amt
FROM tbl_transaction;
As other answers have pointed out, MySQL also has the IF()
function to do this using less verbose syntax. I generally try to avoid this because it is a MySQL-specific extension to SQL that isn't generally supported elsewhere. CASE
is standard SQL and is much more portable across different database engines, and I prefer to write portable queries as much as possible, only using engine-specific extensions when the portable alternative is considerably slower or less convenient.
The following syntax will escape you ONLY ONE quotation mark:
SELECT ''''
The result will be a single quote. Might be very helpful for creating dynamic SQL :).
Actually, pretty much anywhere in typescript, passing a value to a function with a specified type will work as desired as long as the type being passed is compatible.
That being said, the following works...
fetch(`http://swapi.co/api/people/1/`)
.then(res => res.json())
.then((res: Actor) => {
// res is now an Actor
});
I wanted to wrap all of my http calls in a reusable class - which means I needed some way for the client to process the response in its desired form. To support this, I accept a callback lambda as a parameter to my wrapper method. The lambda declaration accepts an any type as shown here...
callBack: (response: any) => void
But in use the caller can pass a lambda that specifies the desired return type. I modified my code from above like this...
fetch(`http://swapi.co/api/people/1/`)
.then(res => res.json())
.then(res => {
if (callback) {
callback(res); // Client receives the response as desired type.
}
});
So that a client can call it with a callback like...
(response: IApigeeResponse) => {
// Process response as an IApigeeResponse
}
You can use this code when using vs code on debugging mode.

In general, synchronized
methods are used to protect access to resources that are accessed concurrently. When a resource that is being accessed concurrently belongs to each instance of your class, you use a synchronized
instance method; when the resource belongs to all instances (i.e. when it is in a static
variable) then you use a synchronized static
method to access it.
For example, you could make a static
factory method that keeps a "registry" of all objects that it has produced. A natural place for such registry would be a static
collection. If your factory is used from multiple threads, you need to make the factory method synchronized
(or have a synchronized
block inside the method) to protect access to the shared static
collection.
Note that using synchronized
without a specific lock object is generally not the safest choice when you are building a library to be used in code written by others. This is because malicious code could synchronize on your object or a class to block your own methods from executing. To protect your code against this, create a private "lock" object, instance or static, and synchronize on that object instead.
If you want the time as well, just go with
datetime.datetime.now().__str__()

Try This. You need pass the authentication to let the server know its a valid user. You need to import these two packages and has to include a jersy jar. If you dont want to include jersy jar then import this package
import sun.misc.BASE64Encoder;
import com.sun.jersey.core.util.Base64;
import sun.net.www.protocol.http.HttpURLConnection;
and then,
String encodedAuthorizedUser = getAuthantication("username", "password");
URL url = new URL("Your Valid Jira URL");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestProperty ("Authorization", "Basic " + encodedAuthorizedUser );
public String getAuthantication(String username, String password) {
String auth = new String(Base64.encode(username + ":" + password));
return auth;

Three Answers :
Simple :
<img>
<xsl:attribute name="src">
<xsl:value-of select="//your/xquery/path"/>
<xsl:value-of select="'vmLogo.gif'"/>
</xsl:attribute>
</img>
Using 'concat' :
<img>
<xsl:attribute name="src">
<xsl:value-of select="concat(//your/xquery/path,'vmLogo.gif')"/>
</xsl:attribute>
</img>
Attribute shortcut as suggested by @TimC
<img src="{concat(//your/xquery/path,'vmLogo.gif')}" />
The other answers seemed more complicated than necessary so I adapted their answers to this short and sweet function.
function allowOnlyNumbers(event) {
if (event.key.length === 1 && /\D/.test(event.key)) {
event.preventDefault();
}
}
It won't do change the behavior of any arrow, enter, shift, ctrl or tab keys because the length of the key property for those events is longer than a single character. It also uses a simple regular expressions to look for any non digit character.
===
and !==
are strict comparison operators:
JavaScript has both strict and type-converting equality comparison. For
strict
equality the objects being compared must have the same type and:
- Two strings are strictly equal when they have the same sequence of characters, same length, and same characters in corresponding positions.
- Two numbers are strictly equal when they are numerically equal (have the same number value).
NaN
is not equal to anything, includingNaN
. Positive and negative zeros are equal to one another.- Two Boolean operands are strictly equal if both are true or both are false.
- Two objects are strictly equal if they refer to the same
Object
.Null
andUndefined
types are==
(but not===
). [I.e. (Null==Undefined
) istrue
but (Null===Undefined
) isfalse
]
The key lies in when you create the project in eclipse.
First step, you create the Java project in eclipse. Right click on the project and choose Team > Share>Git.
In the Configure Git Repository dialog, ensure that you select the option to create the Repository in the parent folder of the project.. Then you can push to github.
N.B: Eclipse will give you a warning about putting git repositories in your workspace. So when you create your project, set your project directory outside the default workspace.
xCode 6 allows you to right click on the provisioning profile under account -> detail (the screen shot you have there) & shows a popup "show in finder".
I don't believe this is a good pattern to use in general. Link will run your onClick event and then navigate to the route, so there will be a slight delay navigating to the new route. A better strategy is to navigate to the new route with the 'to' prop as you have done, and in the new component's componentDidMount() function you can fire your hello function or any other function. It will give you the same result, but with a much smoother transition between routes.
For context, I noticed this while updating my redux store with an onClick event on Link like you have here, and it caused a ~.3 second blank-white-screen delay before mounting the new route's component. There was no api call involved, so I was surprised the delay was so big. However, if you're just console logging 'hello' the delay might not be noticeable.
There is culture problem in regex in C# rather then js. So we need to use regex in US mode for email check. If you don't use ECMAScript mode, your language special characters are imply in A-Z with regex.
Regex.IsMatch(email, @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9_\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$", RegexOptions.ECMAScript)
You can also use &
, |
(and/or) for more flexibility:
values between 5 and 10: A[(A>5)&(A<10)]
values greater than 10 or smaller than 5: A[(A<5)|(A>10)]
Using reshape2
and dplyr
. Your data:
df <- read.table(text=
"tea coke beer water gender
14.55 26.50793651 22.53968254 40 1
24.92997199 24.50980392 26.05042017 24.50980393 2
23.03732304 30.63063063 25.41827542 20.91377091 1
225.51781276 24.6064623 24.85501243 50.80645161 1
24.53662842 26.03706973 25.24271845 24.18358341 2", header=TRUE)
Getting data into correct form:
library(reshape2)
library(dplyr)
df.melt <- melt(df, id="gender")
bar <- group_by(df.melt, variable, gender)%.%summarise(mean=mean(value))
Plotting:
library(ggplot2)
ggplot(bar, aes(x=variable, y=mean, fill=factor(gender)))+
geom_bar(position="dodge", stat="identity")
You can change the listen port as per your requirement. This task can be accomplished in two diffrent ways. By changing config.xml file By changing in admin console Change the listen port in config.xml as per your requirement and bounce the domain. Admin Console Login to AdminConsole->Server->Configuration->ListenPort (Change it) Note: It is a bad practice to edit config.xml and try to edit in admin console(It's a good practise as well)
I was facing the same issue, I made below changes and the issue got resolved.

The error

try this:
ComboBox cbx = new ComboBox();
cbx.DisplayMember = "Text";
cbx.ValueMember = "Value";
EDIT (a little explanation, sory, I also didn't notice your combobox wasn't bound, I blame the lack of caffeine):
The difference between SelectedValue and SelectedItem are explained pretty well here: ComboBox SelectedItem vs SelectedValue
So, if your combobox is not bound to datasource, DisplayMember and ValueMember doesn't do anything, and SelectedValue will always be null, SelectedValueChanged won't be called. So either bind your combobox:
comboBox1.DisplayMember = "Text";
comboBox1.ValueMember = "Value";
List<ComboboxItem> list = new List<ComboboxItem>();
ComboboxItem item = new ComboboxItem();
item.Text = "choose a server...";
item.Value = "-1";
list.Add(item);
item = new ComboboxItem();
item.Text = "S1";
item.Value = "1";
list.Add(item);
item = new ComboboxItem();
item.Text = "S2";
item.Value = "2";
list.Add(item);
cbx.DataSource = list; // bind combobox to a datasource
or use SelectedItem property:
if (cbx.SelectedItem != null)
Console.WriteLine("ITEM: "+comboBox1.SelectedItem.ToString());
UPDATE
as you can see correct solution in Learning answer,
In SQL server management 2014 you can
1.click on "Edit Top 200 Rows"
and then
2.clicking on "Show SQL Pane (ctrl+3)"
and
3.removing TOP (200) from select query
Refer to Shen Lance answer there is not a way to edit Result of select query. and the other answers is only for normal select and only for 200 records.
The best option would be to set a class style in CSS like .showMenu
and .hideMenu
with the various styles inside. Then you can do something like
$("#user_button").addClass("showMenu");
I've found that UC Irvine has a great collection of python modules, pywin32 (win32api) being one of many listed there. I'm not sure how they do with keeping up with the latest versions of these modules but it hasn't let me down yet.

Just bumped into this post, by getting the same error, trying to test if two variables are both empty (or non-empty). That turns out to be a compound comparison - 7.3. Other Comparison Operators - Advanced Bash-Scripting Guide; and I thought I should note the following:
-e
-z
for testing empty variable (string)test
s and &&
them: [ ... ] && [ ... ]
-a
operator in a single test
: [ ... -a ... ]
Here is a working command (searching through all txt files in a directory, and dumping those that grep
finds contain both of two words):
find /usr/share/doc -name '*.txt' | while read file; do \
a1=$(grep -H "description" $file); \
a2=$(grep -H "changes" $file); \
[ ! -z "$a1" -a ! -z "$a2" ] && echo -e "$a1 \n $a2" ; \
done
Edit 12 Aug 2013: related problem note:
Note that when checking string equality with classic test
(single square bracket [
), you MUST have a space between the "is equal" operator, which in this case is a single "equals" =
sign (although two equals' signs ==
seem to be accepted as equality operator too). Thus, this fails (silently):
$ if [ "1"=="" ] ; then echo A; else echo B; fi
A
$ if [ "1"="" ] ; then echo A; else echo B; fi
A
$ if [ "1"="" ] && [ "1"="1" ] ; then echo A; else echo B; fi
A
$ if [ "1"=="" ] && [ "1"=="1" ] ; then echo A; else echo B; fi
A
... but add the space - and all looks good:
$ if [ "1" = "" ] ; then echo A; else echo B; fi
B
$ if [ "1" == "" ] ; then echo A; else echo B; fi
B
$ if [ "1" = "" -a "1" = "1" ] ; then echo A; else echo B; fi
B
$ if [ "1" == "" -a "1" == "1" ] ; then echo A; else echo B; fi
B
In MSVC there is a Microsoft specific keyword for that: __super
MSDN: Allows you to explicitly state that you are calling a base-class implementation for a function that you are overriding.
// deriv_super.cpp
// compile with: /c
struct B1 {
void mf(int) {}
};
struct B2 {
void mf(short) {}
void mf(char) {}
};
struct D : B1, B2 {
void mf(short) {
__super::mf(1); // Calls B1::mf(int)
__super::mf('s'); // Calls B2::mf(char)
}
};
Based on your requirements you can also do the following without libraries like jQuery:
Add this to your head:
window.onload = function () {
document.getElementById("frmSubmit").onsubmit = function onSubmit(form) {
var isValid = true;
//validate your elems here
isValid = false;
if (!isValid) {
alert("Please check your fields!");
return false;
}
else {
//you are good to go
return true;
}
}
}
And your form may still look something like:
<form id="frmSubmit" action="/Submit">
<input type="submit" value="Submit" />
</form>
using FileSaver.js solved my issue thanks for help, below code helped me
'$'

The short answer is "yes". A sample ldapsearch
command to query an Active Directory server is:
ldapsearch \
-x -h ldapserver.mydomain.com \
-D "[email protected]" \
-W \
-b "cn=users,dc=mydomain,dc=com" \
-s sub "(cn=*)" cn mail sn
This would connect to an AD server at hostname ldapserver.mydomain.com
as user [email protected]
, prompt for the password on the command line and show name and email details for users in the cn=users,dc=mydomain,dc=com
subtree.
See Managing LDAP from the Command Line on Linux for more samples. See LDAP Query Basics for Microsoft Exchange documentation for samples using LDAP queries with Active Directory.

In React.js latest version v17.0.1, we can not require the local image we have to import it. like we use to do before = require('../../src/Assets/images/fruits.png'); Now we have to import it like = import fruits from '../../src/Assets/images/fruits.png';
Before React V17.0.1 we can use require(../) and it is working fine.
Further to the excellent accepted answer from Nick Craver, you can throttle the scroll event so that it is not fired so frequently thus increasing browser performance:
var _throttleTimer = null;
var _throttleDelay = 100;
var $window = $(window);
var $document = $(document);
$document.ready(function () {
$window
.off('scroll', ScrollHandler)
.on('scroll', ScrollHandler);
});
function ScrollHandler(e) {
//throttle event:
clearTimeout(_throttleTimer);
_throttleTimer = setTimeout(function () {
console.log('scroll');
//do work
if ($window.scrollTop() + $window.height() > $document.height() - 100) {
alert("near bottom!");
}
}, _throttleDelay);
}
Let us say we are migrating Jenkins LTS from PC1 to PC2 (irrispective of LTS version is same of upgraded). It is easy to use ThinBackUp Plugin for migration or Upgrade of Jenkins version.
Step1: Prepare PC1 for migration
Note: This Thinbackup will also take Plugin Backup which is optional.
Step2: Install Jenkins (Install using .war file or Paste archived version) in PC2.
sc create <Jenkins_PC2Servicename> binPath="<Path_to_Jenkinsexe>/jenkins.exe"
NOTE: If you are using Database setting of SCM in your Jenkins jobs then you need to take extra care as all SCM plugins do not support to carry Database settings with the help of ThinbackUp plugin. e.g. If you are using PTC Integrity SCM Plugin, and some Jenkins jobs are using DB using Integrity, then it will create a directory JENKINS_Home/IntegritySCM, ThinbackUp will not include this DB while taking backup.
Solution: Directly Copy this JENKINS_Home/IntegritySCM folder from PC1 to PC2.
/usr/sbin/host `hostname`
should do the trick. Bear in mind that it's a pretty common configuration for a solaris box to have several IP addresses, though, in which case
/usr/sbin/ifconfig -a inet | awk '/inet/ {print $2}'
will list them all
We were using an incompatible version of Ruby inside of Terminal (Mac), but once we used RVM to switch to Ruby 2.1.2, Cocoapods came back.
Uri path = Uri.fromFile(file );
Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
pdfIntent.setDataAndType(path , "application/pdf");
pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(pdfIntent );
}
catch (ActivityNotFoundException e) {
Toast.makeText(EmptyBlindDocumentShow.this,
"No Application available to viewPDF",
Toast.LENGTH_SHORT).show();
}
}
Assuming you have Files a.txt and b.txt with
cat a.txt
a
b
c
d
1
3
5
cat b.txt
a

7
Keep in mind NR and FNR are awk built-in variables. NR - Gives the total number of records processed. (in this case both in a.txt and b.txt) FNR - Gives the total number of records for each input file (records in either a.txt or b.txt)
awk 'NR==FNR{a[$0];}{if($0 in a)print FILENAME " " NR " " FNR " " $0}' a.txt b.txt
a.txt 1 1 a
a.txt 2 2 b
a.txt 3 3 c
a.txt 4 4 d
a.txt 5 5 1
a.txt 6 6 3
a.txt 7 7 5
b.txt 8 1 a
b.txt 9 2 1
lets Add "next" to skip the first matched with NR==FNR
in b.txt and in a.txt
awk 'NR==FNR{a[$0];next}{if($0 in a)print FILENAME " " NR " " FNR " " $0}' a.txt b.txt
b.txt 8 1 a
b.txt 9 2 1
in b.txt but not in a.txt
awk 'NR==FNR{a[$0];next}{if(!($0 in a))print FILENAME " " NR " " FNR " " $0}' a.txt b.txt
b.txt 10 3 2
b.txt 11 4 6
b.txt 12 5 7
awk 'NR==FNR{a[$0];next}!($0 in a)' a.txt b.txt

I provide this post for both IntelliJ and Eclipse.
Eclipse:
For making unit test for your project, please follow these steps (I am using Eclipse in order to write this test):
1- Click on New -> Java Project.
2- Write down your project name and click on finish.
3- Right click on your project. Then, click on New -> Class.
4- Write down your class name and click on finish.
Then, complete the class like this:
public class Math {
int a, b;
Math(int a, int b) {
this.a = a;
this.b = b;
}
public int add() {
return a + b;
}
}
5- Click on File -> New -> JUnit Test Case.
6- Check setUp() and click on finish. SetUp() will be the place that you initialize your test.
7- Click on OK.
8- Here, I simply add 7 and 10. So, I expect the answer to be 17. Complete your test class like this:
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
public class MathTest {
Math math;
@Before
public void setUp() throws Exception {
math = new Math(7, 10);
}
@Test
public void testAdd() {
Assert.assertEquals(17, math.add());
}
}
9- Write click on your test class in package explorer and click on Run as -> JUnit Test.
10- This is the result of the test.
IntelliJ: Note that I used IntelliJ IDEA community 2020.1 for the screenshots. Also, you need to set up your jre before these steps. I am using JDK 11.0.4.
1- Right-click on the main folder of your project-> new -> directory. You should call this 'test'. 2- Right-click on the test folder and create the proper package. I suggest creating the same packaging names as the original class. Then, you right-click on the test directory -> mark directory as -> test sources root. 3- In the right package in the test directory, you need to create a Java class (I suggest to use Test.java). 4- In the created class, type '@Test'. Then, among the options that IntelliJ gives you, select Add 'JUnitx' to classpath. 5- Write your test method in your test class. The method signature is like:
@Test
public void test<name of original method>(){
...
}
You can do your assertions like below:
Assertions.assertTrue(f.flipEquiv(node1_1, node2_1));
These are the imports that I added:
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
This is the test that I wrote:
You can check your methods like below:
Assertions.assertEquals(<Expected>,<actual>);
Assertions.assertTrue(<actual>);
...
For running your unit tests, right-click on the test and click on Run .
If your test passes, the result will be like below:
I hope it helps. You can see the structure of the project in GitHub https://github.com/m-vahidalizadeh/problem_solving_project.

I was trying to save a record using io.Ebean. I fixed it by re creating my database with utf8mb4 collation, and applied play evolution to re create all tables so that all tables should be recreated with utf-8 collation.
CREATE DATABASE inventory CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
I had a similar issue. Renato's tip worked for me. I used a older version of java class files (under WEB-INF/classes folder) and the problem disappeared. So, it should have been the compiler version mismatch.
from __future__ import with_statement
try:
with open( "a.txt" ) as f :
print f.readlines()
except EnvironmentError: # parent of IOError, OSError *and* WindowsError where available
print 'oops'
If you want different handling for errors from the open call vs the working code you could do:
try:
f = open('foo.txt')
except IOError:
print('error')
else:
with f:
print f.readlines()
This is a pretty good source for info about Haskell and its uses:
