.
public static bool PropertyExists(dynamic obj, string name) {
if (obj == null) return false;
if (obj is IDictionary<string, object> dict) {
return dict.ContainsKey(name);
}
return obj.GetType().GetProperty(name) != null;

Do you need the cursor to be a "wait" cursor only when it's over that particular page/usercontrol? If not, I'd suggest using Mouse.OverrideCursor:
Mouse.OverrideCursor = Cursors.Wait;
try
{
// do stuff
}
finally
{
Mouse.OverrideCursor = null;
}
This overrides the cursor for your application rather than just for a part of its UI, so the problem you're describing goes away.
Not sure its faster with VBA - the fastest way to do it in the normal Excel programm would be:
Ctrl-G
A1:X50 Enter
Delete
Unless you have to do this very often, entering and then triggering the VBAcode is more effort.
And in case you only want to delete formulas or values, you can insert Ctrl-G, Alt-S
to select Goto Special and here select Formulas or Values.
Is there difference in defining Id & name in ApplicationContext xml ? No As of 3.1(spring), id is also defined as an xsd:string type. It means whatever characters allowed in defining name are also allowed in Id. This was not possible prior to Spring 3.1.
Why to use name when it is same as Id ? It is useful for some situations, such as allowing each component in an application to refer to a common dependency by using a bean name that is specific to that component itself.
For example, the configuration metadata for subsystem A may refer to a DataSource via the name subsystemA-dataSource. The configuration metadata for subsystem B may refer to a DataSource via the name subsystemB-dataSource. When composing the main application that uses both these subsystems the main application refers to the DataSource via the name myApp-dataSource. To have all three names refer to the same object you add to the MyApp configuration metadata the following
<bean id="myApp-dataSource" name="subsystemA-dataSource,subsystemB-dataSource" ..../>
Alternatively, You can have separate xml configuration files for each sub-system and then you can make use of
alias to define your own names.
<alias name="subsystemA-dataSource" alias="subsystemB-dataSource"/>
<alias name="subsystemA-dataSource" alias="myApp-dataSource" />
function slugify(content) {
return content.toLowerCase().replace(/ /g,'-').replace(/[^\w-]+/g,'');
}
// slugify('Hello World');
// this will return 'hello-world';
this works for me fine.

@Peter Varo updated Dirk's answer, but Dirk rejected the change. Here's the new answer by Peter:
Although the above snippet is a correct c89 example, one should use the more modern types and guarantees provided by the later standards if possible. Therefore, here is a safer and modern alternative for those who are seeking for the c99 and c11 conforming implementation:
#include <signal.h>
#include <stdlib.h>
#include <stdio.h>
static volatile sig_atomic_t keep_running = 1;
static void sig_handler(int _)
{
(void)_;
keep_running = 0;
}
int main(void)
{
signal(SIGINT, sig_handler);
while (keep_running)
puts("Still running...");
puts("Stopped by signal `SIGINT'");
return EXIT_SUCCESS;
}
C11 Standard: 7.14§2 The header
<signal.h>
declare a type ...sig_atomic_t
which is the (possibly volatile-qualified) integer type of an object that can be accessed as an atomic entity, even in the presence of asynchronous interrupts.
Furthermore:
C11 Standard: 7.14.1.1§5 If the signal occurs other than as the result of calling the
abort
orraise
function, the behavior is undefined if the signal handler refers to any object withstatic
or thread storage duration that is not a lock-free atomic object other than by assigning a value to an object declared asvolatile sig_atomic_t

Yes, just delete the branch by running git push origin :branchname
. To fix a new issue later, branch off from master again.
Suppose there is a method like this that needs testing
The src
property of the tiny image needs checking
function reportABCEvent(cat, type, val) {
var i1 = new Image(1, 1);
var link = getABC('creosote');
link += "&category=" + String(cat);
link += "&event_type=" + String(type);
link += "&event_value=" + String(val);
i1.src = link;
}
The spyOn() below causes the "new Image" to be fed the fake code from the test the spyOn code returns an object that only has a src property
As the variable "hook" is scoped to be visible in the fake code in the SpyOn and also later after the "reportABCEvent" is called
describe("Alphabetic.ads", function() {
it("ABC events create an image request", function() {
var hook={};
spyOn(window, 'Image').andCallFake( function(x,y) {
hook={ src: {} }
return hook;
}
);
reportABCEvent('testa', 'testb', 'testc');
expect(hook.src).
toEqual('[zubzub]&arg1=testa&arg2=testb&event_value=testc');
});
This is for jasmine 1.3 but might work on 2.0 if the "andCallFake" is altered to the 2.0 name
The two common approaches are to submit the form to an invisible iframe, or to use a Flash control such as YUI Uploader. You could also use Java instead of Flash, but this has a narrower install base.
(Shame about the layout table in the first example)
The snippet you're showing doesn't seem to be directly responsible for the error.
This is how you can CAUSE the error:
namespace MyNameSpace
{
int i; <-- THIS NEEDS TO BE INSIDE THE CLASS
class MyClass
{
...
}
}
If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }
.
Though OP is asking about Windows, this error also occurs on Ubuntu Linux and Google lists this result first when you search for the error"QtCreator: No valid kits found".
On Ubuntu this is solved by running:
For Qt5:
sudo apt-get install qt5-default
For Qt4:
sudo apt-get install qt4-dev-tools libqt4-dev libqt4-core libqt4-gui
This question is answered here and here, though those entries are less SEO-friendly...
This is to remove double quotes in a string.
str1 = str.replace(/"/g, "");
alert(str1);
The issue here is that JSON, as a format, is generally parsed in full and then handled in-memory, which for such a large amount of data is clearly problematic.
The solution to this is to work with the data as a stream - reading part of the file, working with it, and then repeating.
The best option appears to be using something like ijson - a module that will work with JSON as a stream, rather than as a block file.
Edit: Also worth a look - kashif's comment about json-streamer
and Henrik Heino's comment about bigjson

Since you have a ::1 localhost
line in your hosts file, it would seem that curl is attempting to use IPv6 to contact your local web server.
Since the web server is not listening on IPv6, the connection fails.
You could try to use the --ipv4
option to curl
, which should force an IPv4 connection when both are available.

git merge --strategy-option theirs
# keep local files
git merge --strategy-option ours
or

Both of the above answers assume that you only have one row for each user and time_stamp. Depending on the application and the granularity of your time_stamp this may not be a valid assumption. If you need to deal with ties of time_stamp for a given user, you'd need to extend one of the answers given above.
To write this in one query would require another nested sub-query - things will start getting more messy and performance may suffer.
I would have loved to have added this as a comment but I don't yet have 50 reputation so sorry for posting as a new answer!
Yet another answer:
def addGetParameters(url, newParams):
(scheme, netloc, path, params, query, fragment) = urlparse.urlparse(url)
queryList = urlparse.parse_qsl(query, keep_blank_values=True)
for key in newParams:
queryList.append((key, newParams[key]))
return urlparse.urlunparse((scheme, netloc, path, params, urllib.urlencode(queryList), fragment))
use the text and value attributes instead of the id
driver.findElementByXpath("//input[@value='cancel'][@title='cancel']").click();
similarly for Next.
Assuming that "a" and "b" are bean properties
rendered="#{bean.a==12 and (bean.b==13 or bean.b==15)}"

If your database client connects with TCP/IP and you have ident auth configured in your pg_hba.conf check that you have an identd installed and running. This is mandatory even if you have only local clients connecting to "localhost".
Also beware that nowadays the identd may have to be IPv6 enabled for Postgresql to welcome clients which connect to localhost.

As stated in earlier answers, FolderBrowserDialog
is the class to use for this. Some people have (justifiable) concerns with the appearance and behaviour of this dialog. The good news is that it was "modernized" in NET Core 3.0, so is now a viable option for those writing either Windows Forms or WPF apps targeting that version or later (you're out of luck if still using NET Framework though).
In .NET Core 3.0, Windows Forms users [sic] a newer COM-based control that was introduced in Windows Vista:
To reference System.Windows.Forms
in a NET Core WPF app, it is necessary to edit the project file and add the following line:
<UseWindowsForms>true</UseWindowsForms>
This can be placed directly after the existing <UseWPF>
element.
Then it's just a case of using the dialog:
using System;
using System.Windows.Forms;
...
using var dialog = new FolderBrowserDialog
{
Description = "Time to select a folder",
UseDescriptionForTitle = true,
SelectedPath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory)
+ Path.DirectorySeparatorChar,
ShowNewFolderButton = true
};
if (dialog.ShowDialog() == DialogResult.OK)
{
...
}
FolderBrowserDialog
has a RootFolder
property that supposedly "sets the root folder where the browsing starts from" but whatever I set this to it didn't make any difference; SelectedPath
seemed to be the better property to use for this purpose, however the trailing backslash is required.
Also, the ShowNewFolderButton
property seems to be ignored as well, the button is always shown regardless.
The main answer worked for me but made the app extremely unresponsive in IE, so I used a timer as suggested. Code looks something like this ($(#contentColumn)
is the div that the JQGrid sits in):
function resizeGrids() {
var reportObjectsGrid = $("#ReportObjectsGrid");
reportObjectsGrid.setGridWidth($("#contentColumn").width());
};
var resizeTimer;
$(window).bind('resize', function () {
clearTimeout(resizeTimer);
resizeTimer = setTimeout(resizeGrids, 60);
});
If e.preventDefault();
is not working you must use e.stopImmediatePropagation();
instead.
For further informations take a look at : What's the difference between event.stopPropagation and event.preventDefault?
$("div.subtab_left li.notebook a").click(function(e) {
e.stopImmediatePropagation();
return false;
});
This is the right answer you want and this solution i have run my self on netbeans

System.out.println(b[i]);
}

I'm using rather specified charset (ISO-8859-2) because not every mail system (for example: http://10minutemail.com) can read UTF-8 mails. If you need this:
function utf8_to_latin2($str)
{
return iconv ( 'utf-8', 'ISO-8859-2' , $str );
}
function my_mail($to,$s,$text,$form, $reply)
{
mail($to,utf8_to_latin2($s),utf8_to_latin2($text),
"From: $form\r\n".
"Reply-To: $reply\r\n".
"X-Mailer: PHP/" . phpversion());
}
I have made another mailer function, because apple device could not read well the previous version.
function utf8mail($to,$s,$body,$from_name="x",$from_a = "[email protected]", $reply="[email protected]")
{
$s= "=?utf-8?b?".base64_encode($s)."?=";
$headers = "MIME-Version: 1.0\r\n";
$headers.= "From: =?utf-8?b?".base64_encode($from_name)."?= <".$from_a.">\r\n";
$headers.= "Content-Type: text/plain;charset=utf-8\r\n";
$headers.= "Reply-To: $reply\r\n";
$headers.= "X-Mailer: PHP/" . phpversion();
mail($to, $s, $body, $headers);
}
What you're trying to do is to monitor the property of attribute in directive. You can watch the property of attribute changes using $observe() as follows:
angular.module('myApp').directive('conversation', function() {
return {
restrict: 'E',
replace: true,
compile: function(tElement, attr) {
attr.$observe('typeId', function(data) {
console.log("Updated data ", data);
}, true);
}
};
});
Keep in mind that I used the 'compile' function in the directive here because you haven't mentioned if you have any models and whether this is performance sensitive.
If you have models, you need to change the 'compile' function to 'link' or use 'controller' and to monitor the property of a model changes, you should use $watch(), and take of the angular {{}} brackets from the property, example:
<conversation style="height:300px" type="convo" type-id="some_prop"></conversation>
And in the directive:
angular.module('myApp').directive('conversation', function() {
return {
scope: {
typeId: '=',
},
link: function(scope, elm, attr) {
scope.$watch('typeId', function(newValue, oldValue) {
if (newValue !== oldValue) {
// You actions here
console.log("I got the new value! ", newValue);
}
}, true);
}
};
});
$str = "I am a PHP Developer";
$str_length = strlen($str);
$str_arr = str_split($str);
for ($i = 0; $i < $str_length; $i++) {
if (isset($str_arr[$i + 1]) && $str_arr[$i] == ' ' && $str_arr[$i] == $str_arr[$i + 1]) {
unset($str_arr[$i]);
}
else {
continue;
}
}
echo implode("", $str_arr);
I'm running Debian 8 (Jessie), Vagrant 1.6.5 and Virtual Box 4.3.x with the same problem.
For me it got fixed executing:
sudo /etc/init.d/vboxdrv setup
Just follow the below link,
Change your Index.html page Script File paths Change your component.html path incase your getting error that could not find the location
https://angular.io/docs/ts/latest/guide/deployment.html#!#dev-deploy
You can get the property the same way as you set it.
foo = {
bar: "value"
}
You set the value
foo["bar"] = "baz";
To get the value
foo["bar"]
will return "baz".
Why do we need virtual functions?
Virtual functions avoid unnecessary typecasting problem, and some of us can debate that why do we need virtual functions when we can use derived class pointer to call the function specific in derived class!the answer is - it nullifies the whole idea of inheritance in large system development, where having single pointer base class object is much desired.
Let's compare below two simple programs to understand the importance of virtual functions:
Program without virtual functions:
#include <iostream>
using namespace std;
class father
{
public: void get_age() {cout << "Fathers age is 50 years" << endl;}
};
class son: public father
{
public : void get_age() { cout << "son`s age is 26 years" << endl;}
};
int main(){
father *p_father = new father;
son *p_son = new son;
p_father->get_age();
p_father = p_son;
p_father->get_age();
p_son->get_age();
return 0;
}
OUTPUT:
Fathers age is 50 years
Fathers age is 50 years
son`s age is 26 years
Program with virtual function:
#include <iostream>
using namespace std;
class father
{
public:
virtual void get_age() {cout << "Fathers age is 50 years" << endl;}
};
class son: public father
{
public : void get_age() { cout << "son`s age is 26 years" << endl;}
};
int main(){
father *p_father = new father;
son *p_son = new son;
p_father->get_age();
p_father = p_son;
p_father->get_age();
p_son->get_age();
return 0;
}
OUTPUT:
Fathers age is 50 years
son`s age is 26 years
son`s age is 26 years
By closely analyzing both the outputs one can understand the importance of virtual functions.
For instance your json looks like this : {"id":1,"content":"Hello, World!"}
You can access this thru angularjs like so:
angular.module('app', [])
.controller('myApp', function($scope, $http) {
$http.get('http://yourapp/api').
then(function(response) {
$scope.datafromapi = response.data;
});
});
Then on your html you would do it like this:
<!doctype html>
<html ng-app="myApp">
<head>
<title>Hello AngularJS</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.3/angular.min.js"></script>
<script src="hello.js"></script>
</head>
<body>
<div ng-controller="myApp">
<p>The ID is {{datafromapi.id}}</p>
<p>The content is {{datafromapi.content}}</p>
</div>
</body>
</html>
This calls the CDN for angularjs in case you don't want to download them.
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.3/angular.min.js"></script>
<script src="hello.js"></script>
Hope this helps.
Move all of your state and your handleClick
function from Header
to your MainWrapper
component.
Then pass values as props to all components that need to share this functionality.
class MainWrapper extends React.Component {
constructor() {
super();
this.state = {
sidbarPushCollapsed: false,
profileCollapsed: false
};
this.handleClick = this.handleClick.bind(this);
}
handleClick() {
this.setState({
sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
profileCollapsed: !this.state.profileCollapsed
});
}
render() {
return (
//...
<Header
handleClick={this.handleClick}
sidbarPushCollapsed={this.state.sidbarPushCollapsed}
profileCollapsed={this.state.profileCollapsed} />
);
Then in your Header's render() method, you'd use this.props
:
<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>
Strings:
>>> n = '4'
>>> print(n.zfill(3))
004
And for numbers:
>>> n = 4
>>> print(f'{n:03}') # Preferred method, python >= 3.6
004
>>> print('%03d' % n)
004
>>> print(format(n, '03')) # python >= 2.6
004
>>> print('{0:03d}'.format(n)) # python >= 2.6 + python 3
004
>>> print('{foo:03d}'.format(foo=n)) # python >= 2.6 + python 3
004
>>> print('{:03d}'.format(n)) # python >= 2.7 + python3
004
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'
.
There's no difference between list implementations in both of your examples. There's however a difference in a way you can further use variable myList in your code.
When you define your list as:
List myList = new ArrayList();
you can only call methods and reference members that are defined in the List interface. If you define it as:
ArrayList myList = new ArrayList();
you'll be able to invoke ArrayList-specific methods and use ArrayList-specific members in addition to those whose definitions are inherited from List.
Nevertheless, when you call a method of a List interface in the first example, which was implemented in ArrayList, the method from ArrayList will be called (because the List interface doesn't implement any methods).
That's called polymorphism. You can read up on it.
Great guide, thank you. Given most instructions here, it almost built for me but I did have one remaining error.
/usr/bin/ld: //usr/local/lib/libglfw3.a(glx_context.c.o): undefined reference to symbol 'dlclose@@GLIBC_2.2.5'

After searching for this error, I had to add -ldl
to the command line.
g++ main.cpp -lglfw3 -lX11 -lXrandr -lXinerama -lXi -lXxf86vm -lXcursor -lGL -lpthread -ldl
Then the "hello GLFW" sample app compiled and linked.
I am pretty new to linux so I am not completely certain what exactly this extra library does... other than fix my linking error. I do see that cmd line switch in the post above, however.
There is easy way of doing this. I don't know why people are giving complicated answers.
Double click SSIS package. Then go to connection manager, select DestinationConnectionOLDB and then add password next to login field.

Do same for SourceConnectionOLDB.

Previous answers will strip your decimal point. If you want to save your decimal, you might want to
String str = "My values are : 900.00, 700.00, 650.50";
String[] values = str.split("[^\\d.?\\d]");
// split on wherever they are not digits except the '.' decimal point
// values: { "900.00", "700.00", "650.50"}
Try enabling vertical mode, using \G
to execute the query instead of ;
:
mysql> SELECT * FROM sometable \G
Your results will be listed in the vertical mode, so each column value will be printed on a separate line. The output will be narrower but obviously much longer.
I think:
np.column_stack((a, zeros(shape(a)[0])))
is more elegant.

This is what did it for me MessageDeliveryMode is the enum the bean will have the value PERSISTENT:
<bean class="org.springframework.amqp.core.MessageDeliveryMode" factory-method="valueOf">

I think init_js should use declare instead of local!
function scan3() {
declare -n outvar=$1 # -n makes it a nameref.
local nl=$'\x0a'
outvar="output${nl}${nl}" # two total. quotes preserve newlines
}
If you want it based on the screen height, and not the window height:
const height = 0.7 * screen.height
// jQuery
$('.header').height(height)
// Vanilla JS
document.querySelector('.header').style.height = height + 'px'
// If you have multiple <div class="header"> elements
document.querySelectorAll('.header').forEach(function(node) {
node.style.height = height + 'px'
})
Use the %lf
format specifier to read a double:
double a;
scanf("%lf",&a);
Wikipedia has a decent reference for available format specifiers.
You'll need to use the %lf
format specifier to print out the results as well:
printf("%lf %lf",a,b);
table-layout: fixed
will get force the cells to fit the table (and not the other way around), e.g.:
<table style="border: 1px solid black; width: 100%; word-wrap:break-word;
table-layout: fixed;">
<tr>
<td>
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

</tr>
</table>
Keep in mind that the copy constructor limits the class type to that of the copy constructor. Consider the example:
// Need to clone person, which is type Person
Person clone = new Person(person);
This doesn't work if person
could be a subclass of Person
(or if Person
is an interface). This is the whole point of clone, is that it can can clone the proper type dynamically at runtime (assuming clone is properly implemented).
Person clone = (Person)person.clone();
or
Person clone = (Person)SomeCloneUtil.clone(person); // See Bozho's answer
Now person
can be any type of Person
assuming that clone
is properly implemented.

In latin1 each character is exactly one byte long. In utf8 a character can consist of more than one byte. Consequently utf8 has more characters than latin1 (and the characters they do have in common aren't necessarily represented by the same byte/bytesequence).
There seems to be quite a variety of ways of preventing the system keyboard from appearing, both programmatically and in xml. However, this is the way that has worked for me while supporting pre API 11 devices.
// prevent system keyboard from appearing
if (android.os.Build.VERSION.SDK_INT >= 11) {
editText.setRawInputType(InputType.TYPE_CLASS_TEXT);
editText.setTextIsSelectable(true);
} else {
editText.setRawInputType(InputType.TYPE_NULL);
editText.setFocusable(true);
}
Your countLines(String filename)
method throws IOException.
You can't use it in a member declaration. You'll need to perform the operation in a main(String[] args)
method.
Your main(String[] args)
method will get the IOException thrown to it by countLines and it will need to handle or declare it.
Try this to just throw the IOException from main
public class MyClass {
private int lineCount;
public static void main(String[] args) throws IOException {
lineCount = LineCounter.countLines(sFileName);
}
}
or this to handle it and wrap it in an unchecked IllegalArgumentException:
public class MyClass {
private int lineCount;
private String sFileName = "myfile";
public static void main(String[] args) throws IOException {
try {
lineCount = LineCounter.countLines(sFileName);
} catch (IOException e) {
throw new IllegalArgumentException("Unable to load " + sFileName, e);
}
}
}
Just found another reason why an element goes blurry when being transformed. I was using transform: translate3d(-5.5px, -18px, 0);
to re-position an element once it had been loaded in, however that element became blurry.
I tried all the suggestions above but it turned out that it was due to me using a decimal value for one of the translate values. Whole numbers don't cause the blur, and the further away I went from the whole number the worse the blur became.
i.e. 5.5px
blurs the element the most, 5.1px
the least.
Just thought I'd chuck this here in case it helps anybody.
See this blog post. It uses jQuery, but it should help you even if you are not using it.
Basically you add this to your document.ready()
$('iframe').load(function() {
RunAfterIFrameLoaded();
});
if you want to disable the values of the dropdown
$('select option:not(selected)').prop('disabled', true);
$('select').prop('disabled', true);
Depending on what you're wanting, you can use…
rake db:create
…to build the database from scratch from config/database.yml
, or…
rake db:schema:load
…to build the database from scratch from your schema.rb
file.
Basic validation can be performed by choosing the type attribute of input elements. For example:
<input type="email" />
<input type="URL" />
<input type="number" />
using pattern attribute like:
<input type="text" pattern="[1-4]{5}" />
required attribute
<input type="text" required />
maxlength:
<input type="text" maxlength="20" />
min & max:
<input type="number" min="1" max="4" />
Ruby does have a method for this:
File.readlines('foo').each do |line|
you can do it by Dynamic Web Project –> RightClick –> Java EE Tools –> Generate Deployment Descriptor Stub.
None of the answers helped me, so I'm posting the solution that worked for me, all I had to do is to import the SQLPS module, I realized this when by accident I ran the Restore-SqlDatabase command and started working, meaning that the assembly was referenced in that module somehow.
Just run:
Import-module SQLPS
Note: Thanks Jason for noting that SQLPS is deprecated
instead run:
Import-Module SqlServer
or
Install-Module SqlServer
from a table?
You can use this if you have no foreign keys to other tables
truncate table TableName
or
delete TableName
if you want all tables
sp_msforeachtable 'delete ?'
You can use a TreeMap data structure
. TreeMap
is implemented as a red black tree, which is a self-balancing binary search tree.
From the Fragment
documentation:
Often you will want one Fragment to communicate with another, for example to change the content based on a user event. All Fragment-to-Fragment communication is done through the associated Activity. Two Fragments should never communicate directly.
So I suggest you have look on the basic fragment training docs in the documentation. They're pretty comprehensive with an example and a walk-through guide.
I had the same problem, however, it worked for me with the following settings:
bulk insert schema.table
from '\\your\data\source.csv'
with (
datafiletype = 'char'
,format = 'CSV'
,firstrow = 2
,fieldterminator = '|'
,rowterminator = '\n'
,tablock
)
My CSV-File looks like this:
"col1"|"col2"
"val1"|"val2"
"val3"|"val4"
My problem was, I had rowterminator set to '0x0a' before, it did not work. Once I changed it to '\n', it started working...
As @Kimble has said, with Jackson 2, using the default formatting is very easy; simply register JodaModule
on your ObjectMapper
.
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JodaModule());
For custom serialization/de-serialization of DateTime
, you need to implement your own StdScalarSerializer
and StdScalarDeserializer
; it's pretty convoluted, but anyway.
For example, here's a DateTime
serializer that uses the ISODateFormat
with the UTC time zone:
public class DateTimeSerializer extends StdScalarSerializer<DateTime> {
public DateTimeSerializer() {
super(DateTime.class);
}
@Override
public void serialize(DateTime dateTime,
JsonGenerator jsonGenerator,
SerializerProvider provider) throws IOException, JsonGenerationException {
String dateTimeAsString = ISODateTimeFormat.withZoneUTC().print(dateTime);
jsonGenerator.writeString(dateTimeAsString);
}
}
And the corresponding de-serializer:
public class DateTimeDesrializer extends StdScalarDeserializer<DateTime> {
public DateTimeDesrializer() {
super(DateTime.class);
}
@Override
public DateTime deserialize(JsonParser jsonParser,
DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
try {
JsonToken currentToken = jsonParser.getCurrentToken();
if (currentToken == JsonToken.VALUE_STRING) {
String dateTimeAsString = jsonParser.getText().trim();
return ISODateTimeFormat.withZoneUTC().parseDateTime(dateTimeAsString);
}
} finally {
throw deserializationContext.mappingException(getValueClass());
}
}
Then tie these together with a module:
public class DateTimeModule extends SimpleModule {
public DateTimeModule() {
super();
addSerializer(DateTime.class, new DateTimeSerializer());
addDeserializer(DateTime.class, new DateTimeDeserializer());
}
}
Then register the module on your ObjectMapper
:
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new DateTimeModule());
I have no serial device here to test it, but if you have python and dbus you can try it yourself.
import dbus
bus = dbus.SystemBus()
hwmanager = bus.get_object('org.freedesktop.Hal', '/org/freedesktop/Hal/Manager')
hwmanager_i = dbus.Interface(hwmanager, 'org.freedesktop.Hal.Manager')
print hwmanager_i.FindDeviceByCapability("serial")
If it fails you can search inside hwmanager_i.GetAllDevicesWithProperties()
to see if the capability name "serial" that I just guessed has a different name.

Try this:
function explode(){
alert("Boom!");
}
setTimeout(explode, 2000);
I just wanted to bring a small contribution, because I have been able to debug on my Nexus 5 device on Windows 8, without doing all of this.
When I plugged it, there wasn't any yellow exclamation mark within Device Manager. So for me, the drivers were OK. But the device was not listed within my Eclipse DDMS. After a little bit of searching, it was just an option to change in the device settings. By default, the Nexus 5 USB computer connection is in MTP mode (Media Device).
What you have to do is:
I hope this will help!
componentWillReceiveProps
is being deprecated because using it "often leads to bugs and inconsistencies".
If something changes from the outside, consider resetting the child component entirely with key
.
Providing a key
prop to the child component makes sure that whenever the value of key
changes from the outside, this component is re-rendered. E.g.,
<EmailInput
defaultEmail={this.props.user.email}
key={this.props.user.id}
/>
On its performance:
While this may sound slow, the performance difference is usually insignificant. Using a key can even be faster if the components have heavy logic that runs on updates since diffing gets bypassed for that subtree.
instead of receiving the json string a model binding is better. For example:
[HttpPost]
public ActionResult AddUser(UserAddModel model)
{
if (ModelState.IsValid) {
return Json(new { Response = "Success" });
}
return Json(new { Response = "Error" });
}
<script>
function submitForm() {
$.ajax({
type: 'POST',
url: "@Url.Action("AddUser")",
contentType: "application/json; charset=utf-8",
dataType: 'json',
data: $("form[name=UserAddForm]").serialize(),
success: function (data) {
console.log(data);
}
});
}
</script>

If you need to store a password in memory and would like to have it encrypted you should use SecureString:
http://msdn.microsoft.com/en-us/library/system.security.securestring.aspx
For more general uses I would use a FIPS approved algorithm such as Advanced Encryption Standard, formerly known as Rijndael. See this page for an implementation example:

You can do the following:
TimeSpan duration = b - a;
There's plenty of built in methods in the timespan class to do what you need, i.e.
duration.TotalSeconds
duration.TotalMinutes
More info can be found here.
You can use exception handling if you want to be very verbose:
try:
del dict[key]
except KeyError: pass
This is slower, however, than the pop()
method, if the key doesn't exist.
my_dict.pop('key', None)
It won't matter for a few keys, but if you're doing this repeatedly, then the latter method is a better bet.
The fastest approach is this:
if 'key' in dict:
del myDict['key']
But this method is dangerous because if 'key'
is removed in between the two lines, a KeyError
will be raised.
There seems to have been an update some time in the past 3 years which changes the location of where to place themes in order to get them working.
Previosuly, themes were located in the Notepad++ installation folder. Now they are located in AppData:
C:\Users\YOUR_USER\AppData\Roaming\Notepad++\themes
My answer is an update to @Amit-IO's answer about manually copying the themes.
%AppData%\Notepad++
.themes
does not exist, create it.%AppData%\Notepad++\themes
.Settings -> Style Configurator
. The new theme(s) will appear in the list.Another way - from an ISO 8601 date.
var timestamp = 1293683278;_x000D_
var date = new Date(timestamp * 1000);_x000D_
var iso = date.toISOString().match(/(\d{2}:\d{2}:\d{2})/)_x000D_
alert(iso[1]);
_x000D_
You can get the maximum like this:
>>> import pandas as pd
>>> df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
>>> df
A B
0 1 -2
1 2 8
2 3 1
>>> df[["A", "B"]]
A B
0 1 -2
1 2 8
2 3 1
>>> df[["A", "B"]].max(axis=1)
0 1
1 8
2 3
and so:
>>> df["C"] = df[["A", "B"]].max(axis=1)
>>> df
A B C
0 1 -2 1
1 2 8 8
2 3 1 3
If you know that "A" and "B" are the only columns, you could even get away with
>>> df["C"] = df.max(axis=1)
And you could use .apply(max, axis=1)
too, I guess.
I am using jquery.min v2.0.3 . It's for me better to use following:
var select = jQuery("#selecter");
jQuery("`<option/>`",{value: someValue, text: someText}).appendTo(select);
as following:
var select = jQuery("#selecter");
jQuery(document.createElement('option')).prop({value: someValue, text: someText}).appendTo(select);
Processing time of first code is much lower than second code.
You can also consider using Record
, like this:
const someArray: Record<string, string>[] = [
{'first': 'one'},
{'second': 'two'}
];
Or write something like this:
const someArray: {key: string, value: string}[] = [
{key: 'first', value: 'one'},
{key: 'second', value: 'two'}
];
I had exactly the same error. My network is an internal one of a company. I downloaded neon-eclipse for java developpers. These steps worked for me:
1- I downloaded a VPN client on my PC to be totally blinded from the network. Shellfire I used. Use free account and connect to Shellserver.
2- Inside the windows firewall, I added incoming rule for Eclipse. Navigate to where eclipse exe is found.
3- Perform Maven Update project.
Then the project was able to fetch from the maven repository.
hope it helps.
As other guys commented before you can write your own procedure with anonymous function to solve this issue.
I used two ways to solve it:
func Find(slice interface{}, f func(value interface{}) bool) int {
s := reflect.ValueOf(slice)
if s.Kind() == reflect.Slice {
for index := 0; index < s.Len(); index++ {
if f(s.Index(index).Interface()) {
return index
}
}
}
return -1
}
Uses example:
type UserInfo struct {
UserId int
}
func main() {
var (
destinationList []UserInfo
userId int = 123
)
destinationList = append(destinationList, UserInfo {
UserId : 23,
})
destinationList = append(destinationList, UserInfo {
UserId : 12,
})
idx := Find(destinationList, func(value interface{}) bool {
return value.(UserInfo).UserId == userId
})
if idx < 0 {
fmt.Println("not found")
} else {
fmt.Println(idx)
}
}
Second method with less computational cost:
func Search(length int, f func(index int) bool) int {
for index := 0; index < length; index++ {
if f(index) {
return index
}
}
return -1
}
Uses example:
type UserInfo struct {
UserId int
}
func main() {
var (
destinationList []UserInfo
userId int = 123
)
destinationList = append(destinationList, UserInfo {
UserId : 23,
})
destinationList = append(destinationList, UserInfo {
UserId : 123,
})
idx := Search(len(destinationList), func(index int) bool {
return destinationList[index].UserId == userId
})
if idx < 0 {
fmt.Println("not found")
} else {
fmt.Println(idx)
}
}
I can speak from first hand experience that it is often a good idea to place the web server and database on different machines. If you have an application that is resource intensive, it can easily cause the CPU cycles on the machine to peak, essentially bringing the machine to a halt. However, if your application has limited use of the database, it would probably be no big deal to have them share a server.
The parameter ui
has a property called selected
which is a reference to the selected dom element, you can call innerHTML
on that element.
Your code $('.ui-selected').innerHTML
tries to return the innerHTML
property of a jQuery wrapper element for a dom element with class ui-selected
$(function () {
$("#select-image").selectable({
selected: function (event, ui) {
var $variable = ui.selected.innerHTML; // or $(ui.selected).html()
console.log($variable);
}
});
});
Demo: Fiddle
You can use bellow code example for date string like mdate and Now() like toDay, you can also calculate deference between both date like Aging
Public Sub test(mdate As String)
Dim toDay As String
mdate = Round(CDbl(CDate(mdate)), 0)
toDay = Round(CDbl(Now()), 0)
Dim Aging as String
Aging = toDay - mdate
MsgBox ("So aging is -" & Aging & vbCr & "from the date - " & _
Format(mdate, "dd-mm-yyyy")) & " to " & Format(toDay, "dd-mm-yyyy"))
End Sub
NB: Used CDate
for convert Date String to Valid Date
I am using this in Office 2007 :)
A poor man's option is to use the tool tig
1 on HEAD
, search for the commit, and then visually follow the line from that commit back up until a merge commit is seen. The default merge message should specify what branch is getting merged to where :)
1 Tig is an ncurses-based text-mode interface for Git. It functions mainly as a Git repository browser, but it can also assist in staging changes for commit at chunk level and act as a pager for output from various Git commands.
Try gzipping some data through the gzip libary like this...
import gzip
content = "Lots of content here"
f = gzip.open('Onlyfinnaly.log.gz', 'wb')
f.write(content)
f.close()
... then run your code as posted ...
import gzip
f=gzip.open('Onlyfinnaly.log.gz','rb')
file_content=f.read()
print file_content
This method worked for me as for some reason the gzip library fails to read some files.
I have python 3.5 with anaconda. First I tried everything given above but it did not work for me on windows 10 64bit. So I simply tried:-
If you just have one version, then type in cmd:
C:/>conda install tensorflow
for multiple versions of python, type in cmd:
C:/>conda install tensorflow python=version(e.g.python=3.5)
It works, just give it a try.
After installation open ipython console and import tensorflow:
import tensorflow
If tensorflow installed properly then you are ready to go. Enjoy machine learning:-)
Modern BASH has support for regular expressions:
while read -r line; do
if [[ $line =~ ^potato:\ ([0-9]+) ]]; then
echo "${BASH_REMATCH[1]}"
fi
done
You could do something like this
public abstract MyAbstractClass {
@Autowire
private MyMock myMock;
protected String sayHello() {
return myMock.getHello() + ", " + getName();
}
public abstract String getName();
}
// this is your JUnit test
public class MyAbstractClassTest extends MyAbstractClass {
@Mock
private MyMock myMock;
@InjectMocks
private MyAbstractClass thiz = this;
private String myName = null;
@Override
public String getName() {
return myName;
}
@Test
public void testSayHello() {
myName = "Johnny"
when(myMock.getHello()).thenReturn("Hello");
String result = sayHello();
assertEquals("Hello, Johnny", result);
}
}
In C/C++ programming there are two types of strings: the C strings and the standard strings. With the <string>
header, we can use the standard strings. On the other hand, the C strings are just an array of normal chars. So, in order to convert a standard string to a C string, we use the c_str()
function.
for example
// a string to a C-style string conversion//
const char *cstr1 = str1.c_str();
cout<<"Operation: *cstr1 = str1.c_str()"<<endl;
cout<<"The C-style string c_str1 is: "<<cstr1<<endl;
cout<<"\nOperation: strlen(cstr1)"<<endl;
cout<<"The length of C-style string str1 = "<<strlen(cstr1)<<endl;
And the output will be,
Operation: *cstr1 = str1.c_str()
The C-style string c_str1 is: Testing the c_str
Operation: strlen(cstr1)
The length of C-style string str1 = 17
For all those who came here and did indeed use Date typed Variables, here is the solution I found. It does also apply to TypeScript.
I was facing this error because I tried to compare two dates using the following Method
var res = dat1.getTime() > dat2.getTime(); // or any other comparison operator
However Im sure I used a Date object, because Im using angularjs with typescript, and I got the data from a typed API call.
Im not sure why the error is raised, but I assume that because my Object was created by JSON deserialisation, possibly the getTime()
method was simply not added to the prototype.
In this case, recreating a date-Object based on your dates will fix the issue.
var res = new Date(dat1).getTime() > new Date(dat2).getTime()
I was right about this. Types will be cast to the according type but they wont be instanciated. Hence there will be a string cast to a date, which will obviously result in a runtime exception.
The trick is, if you use interfaces with non primitive only data such as dates or functions, you will need to perform a mapping after your http request.
class Details {
description: string;
date: Date;
score: number;
approved: boolean;
constructor(data: any) {
Object.assign(this, data);
}
}
and to perform the mapping:
public getDetails(id: number): Promise<Details> {
return this.http
.get<Details>(`${this.baseUrl}/api/details/${id}`)
.map(response => new Details(response.json()))
.toPromise();
}
for arrays use:
public getDetails(): Promise<Details[]> {
return this.http
.get<Details>(`${this.baseUrl}/api/details`)
.map(response => {
const array = JSON.parse(response.json()) as any[];
const details = array.map(data => new Details(data));
return details;
})
.toPromise();
}

Most of the time @cer solution works but if in case its not working then try installing it in base R (NOT in R studio). As R studio runs base R executable in background so new package will be available in R studio as well. [my experience in macOS]
It is actually quite simple.

The problem is that certain third party libraries require file pathnames rather than input streams. Most of the answers don't address this issue.
In this case, one workaround is to copy the resource contents into a temporary file. The following example uses jUnit's TemporaryFolder
.
private List<String> decomposePath(String path){
List<String> reversed = Lists.newArrayList();
File currFile = new File(path);
while(currFile != null){
reversed.add(currFile.getName());
currFile = currFile.getParentFile();
}
return Lists.reverse(reversed);
}
private String writeResourceToFile(String resourceName) throws IOException {
ClassLoader loader = getClass().getClassLoader();
InputStream configStream = loader.getResourceAsStream(resourceName);
List<String> pathComponents = decomposePath(resourceName);
folder.newFolder(pathComponents.subList(0, pathComponents.size() - 1).toArray(new String[0]));
File tmpFile = folder.newFile(resourceName);
Files.copy(configStream, tmpFile.toPath(), REPLACE_EXISTING);
return tmpFile.getAbsolutePath();
}
Here's a more portable version (just for fun, it is not necessary in your case):
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from subprocess import Popen, PIPE, STDOUT
try:
from subprocess import DEVNULL # py3k
except ImportError:
import os
DEVNULL = open(os.devnull, 'wb')
text = u"René Descartes"
p = Popen(['espeak', '-b', '1'], stdin=PIPE, stdout=DEVNULL, stderr=STDOUT)
p.communicate(text.encode('utf-8'))
assert p.returncode == 0 # use appropriate for your program error handling here
Kevin's code creates redundant MarginLayoutParams
object. Simpler version:
ImageView image = (ImageView) findViewById(R.id.main_image);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(image.getLayoutParams());
lp.setMargins(50, 100, 0, 0);
image.setLayoutParams(lp);
this ended up working for me:
gpg -a --export-secret-keys > exportedKeyFilename.asc
you can name keyfilename.asc by any name as long as you keep on the .asc extension.
this command copies all secret-keys on a user's computer to keyfilename.asc in the working directory of where the command was called.
To Export just 1 specific secret key instead of all of them:
gpg -a --export-secret-keys keyIDNumber > exportedKeyFilename.asc
keyIDNumber is the number of the key id for the desired key you are trying to export.

I believe that echo
outputs a trailing newline. Try using -n
as a parameter to echo to skip the newline.
After my question resulted in no satisfying result (because C++ doesn't implement tag-based init for structures), I took the trick I found here: Are members of a C++ struct initialized to 0 by default?
For you it would amount to do that:
address temp_address = {}; // will zero all fields in C++
temp_address.city = "Hamilton";
temp_address.prov = "Ontario";
This is certainly the closest to what you wanted originally (zero all the fields except those you want to initialize).
Prior to PHP 5.2.0 and above you should use filter_input()
which is especially created for that to get a specific external user inputs such as get, post or cookie variables by name and optionally filters it to avoid any XSS/Injection attacks on your site. For example:
$user = filter_input(INPUT_POST, 'username');
You may use one of INPUT_GET, INPUT_POST, INPUT_COOKIE, INPUT_SERVER, or INPUT_ENV.
By using optional 3rd argument, you can extend it by variety of filters (for validating, sanitizing, filtering or other), e.g. FILTER_SANITIZE_SPECIAL_CHARS
, FILTER_SANITIZE_ENCODED
, etc.
For example:
<?php
$search_html = filter_input(INPUT_GET, 'search', FILTER_SANITIZE_SPECIAL_CHARS);
$search_url = filter_input(INPUT_GET, 'search', FILTER_SANITIZE_ENCODED);
echo "You have searched for $search_html.\n";
echo "<a href='?search=$search_url'>Search again.</a>";
?>
The syntax is:
mixed
filter_input
( int $type , string $variable_name [, int $filter = FILTER_DEFAULT [, mixed $options ]] )(PHP 5 >= 5.2.0, PHP 7)
See also: Why is better to use filter_input()?
What i have done is that import a new project into eclipse workspace, and that path of that was be
android-sdk-macosx/extras/google/google_play_services/libproject/google-play-services_lib
and add as library in your project.. that it .. simple!! you might require to add support library in your project.
Your execution plan should make this clear; the JOIN takes precedence, after which the results are filtered.
Apart from string interpolation, you can also call a function using back-tick.
var sayHello = function () {
console.log('Hello', arguments);
}
// To call this function using ``
sayHello`some args`; // Check console for the output
// Or
sayHello`
some args
`;
Check styled component. They use it heavily.
I am trying to write a class that is "both" a list
or a dict
. I want the programmer to be able to both "cast" this object to a list
(dropping the keys) or dict
(with the keys).
Looking at the way Python currently does the dict()
cast: It calls Mapping.update()
with the object that is passed. This is the code from the Python repo:
def update(self, other=(), /, **kwds):
''' D.update([E, ]**F) -> None. Update D from mapping/iterable E and F.
If E present and has a .keys() method, does: for k in E: D[k] = E[k]
If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v
In either case, this is followed by: for k, v in F.items(): D[k] = v
'''
if isinstance(other, Mapping):
for key in other:
self[key] = other[key]
elif hasattr(other, "keys"):
for key in other.keys():
self[key] = other[key]
else:
for key, value in other:
self[key] = value
for key, value in kwds.items():
self[key] = value
The last subcase of the if statement, where it is iterating over other
is the one most people have in mind. However, as you can see, it is also possible to have a keys()
property. That, combined with a __getitem__()
should make it easy to have a subclass be properly casted to a dictionary:
class Wharrgarbl(object):
def __init__(self, a, b, c, sum, version='old'):
self.a = a
self.b = b
self.c = c
self.sum = 6
self.version = version
def __int__(self):
return self.sum + 9000
def __keys__(self):
return ["a", "b", "c"]
def __getitem__(self, key):
# have obj["a"] -> obj.a
return self.__getattribute__(key)
Then this will work:
>>> w = Wharrgarbl('one', 'two', 'three', 6)
>>> dict(w)
{'a': 'one', 'c': 'three', 'b': 'two'}
I think this should work...
var query = from m in context.MyTable
where m.MyContainerId == '1' // or what ever the foreign key name is...
select m;
var count = query.Count();
I would like to recommend:
Microsoft Edge Run Wrapper
https://github.com/mihula/RunEdge
You run it this way:
RunEdge.exe [URL]
Examples:
RunEdge.exe http://google.com
RunEdge.exe www.stackoverflow.com
It is not exactly new way how to do it, but it is wrapped as exe file, which could be useful in some situations. For me it is way how to start Edge from IBM Notes Basic client.
FirePHP can be useful as well.
I think the easiest way to accomplish it is to use querystring instead of HTTP headers.
Had same issue with Android Studio 3.3 Canary 13.
I was able to solve it by following these steps:
When you complete these steps the module will be copied into your project again, AS will start syncing Gradle again and that succeeds without errors :-) Check your GIT status and you will see as soon as you add your module directory to GIT again that nothing has changed to your working directory. So it's purely an issue with AS that gets somehow out-of-sync...
Based my solution on this comment: https://issuetracker.google.com/issues/37008041#comment3
BundleConfig
is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)
To add this file, first you need to add the Microsoft.AspNet.Web.Optimization
nuget package to your web project:
Install-Package Microsoft.AspNet.Web.Optimization
Then under the App_Start folder create a new cs file called BundleConfig.cs
. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):
using System.Web;
using System.Web.Optimization;
namespace CodeRepository.Web
{
public class BundleConfig
{
// For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Scripts/jquery-{version}.js"));
bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
"~/Scripts/jquery.validate*"));
// Use the development version of Modernizr to develop with and learn from. Then, when you're
// ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
"~/Scripts/modernizr-*"));
bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
"~/Scripts/bootstrap.js",
"~/Scripts/respond.js"));
bundles.Add(new StyleBundle("~/Content/css").Include(
"~/Content/bootstrap.css",
"~/Content/site.css"));
}
}
}
Then modify your Global.asax and add a call to RegisterBundles()
in Application_Start()
:
using System.Web.Optimization;
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}

If you want an "early exit" for a situation in which there was no error, then use the accepted answer posted by @piotrm. Most typically, however, you will be bailing due to an error condition (especially in a SQL procedure).
As of MySQL v5.5 you can throw an exception. Negating exception handlers, etc. that will achieve the same result, but in a cleaner, more precise manner.
Here's how:
DECLARE CUSTOM_EXCEPTION CONDITION FOR SQLSTATE '45000';
IF <Some Error Condition> THEN
SIGNAL CUSTOM_EXCEPTION
SET MESSAGE_TEXT = 'Your Custom Error Message';
END IF;
Note SQLSTATE '45000'
equates to "Unhandled user-defined exception condition". By default, this will produce an error code of 1644
(which has that same meaning). Note that you can throw other condition codes or error codes if you want (plus additional details for exception handling).
For more on this subject, check out:
https://dev.mysql.com/doc/refman/5.5/en/signal.html
How to raise an error within a MySQL function
Addendum
As I'm re-reading this post of mine, I realized I had something additional to add. Prior to MySQL v5.5, there was a way to emulate throwing an exception. It's not the same thing exactly, but this was the analogue: Create an error via calling a procedure which does not exist. Call the procedure by a name which is meaningful in order to get a useful means by which to determine what the problem was. When the error occurs, you'll get to see the line of failure (depending on your execution context).
For example:
CALL AttemptedToInsertSomethingInvalid;
Note that when you create a procedure, there is no validation performed on such things. So while in something like a compiled language, you could never call a function that wasn't there, in a script like this it will simply fail at runtime, which is exactly what is desired in this case!
Many users fall in this thread expecting to find a solution for blank pages being displayed while using nginx+php-fpm, me being one of them. This is a recap of what I ended up doing after reading many of the answers here plus my own investigations (updated to php7.2):
1) Open /etc/php/7.2/fpm/pool.d/www.conf
and check the value of parameter listen
.
listen = /var/run/php/php7.2-fpm.sock
2) Parameter listen
should match fastcgi_pass
parameter in your site configuration file (i,e: /etc/nginx/sites-enabled/default
).
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
3) Check the file actually exists:
$ file /var/run/php/php7.2-fpm.sock
/var/run/php/php7.2-fpm.sock: socket
4) If it doesn't exist that means php7.2-fpm is not running, so you need to restart it:
$ sudo /etc/init.d/php7.2-fpm restart
[ ok ] Restarting php7.2-fpm (via systemctl): php7.2-fpm.service.
With regard to the location
section in /etc/nginx/sites-enabled/default
:
# pass PHP scripts to FastCGI server
#
location ~ \.php$ {
include snippets/fastcgi-php.conf;
# With php-fpm (or other unix sockets):
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
}
Check the file snippets/fastcgi-php.conf
exists at location /etc/nginx/
:
$ file /etc/nginx/snippets/fastcgi-php.conf
/etc/nginx/snippets/fastcgi-php.conf: ASCII text
This file contains a list of variable definitions required by php7.2-fpm. The variables are defined directly or through an include of a separated file.
include fastcgi.conf;
This file is located at /etc/nginx/fastcgi.conf
and it looks like:
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
...
fastcgi_param REDIRECT_STATUS 200;
nginx includes two possible parameter files: fastcgi_params and fastcgi.conf. The difference between both is the definition of variable SCRIPT_FILENAME
:
$ diff fastcgi_params fastcgi.conf
1a2
> fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
To make a long story short, fastcgi.conf should always work. If for some reason you're set up is using fastcgi_params, you should define SCRIPT_FILENAME
:
location ~ \.php$ {
include snippets/fastcgi-php.conf;
# With php-fpm (or other unix sockets):
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
Now reload nginx configuration:
$ sudo nginx -s reload
And check a php file is displayed correctly. For instance:
/var/www/html/test.php
<pre><?php var_export($_SERVER)?></pre>
Where /var/www/html
is the path to the document root.
If despite all that, you're still seeing a blank file, make sure your php.ini
has short_open_tag
enabled (if you're testing a PHP page with short tags).
I know this question is old, but this is a much easier alternative:
header_remove();
But be careful! It will erase ALL headers, including Cookies, Session, etc., as explained in the docs.
try - =SUM(IF(FREQUENCY(MATCH(COLUMNRANGE,COLUMNRANGE,0),MATCH(COLUMNRANGE,COLUMNRANGE,0))>0,1))
where COLUMNRANGE = the range where you have these values.
e.g. - =SUM(IF(FREQUENCY(MATCH(C12:C26,C12:C26,0),MATCH(C12:C26,C12:C26,0))>0,1))
Press Ctrl+Shift+Enter to make the formula an array (won't calculate correctly otherwise)
I think that your problem is in the location of the image. You shall place it in your source, and then use it like this:
JButton button = new JButton();
try {
Image img = ImageIO.read(getClass().getResource("resources/water.bmp"));
button.setIcon(new ImageIcon(img));
} catch (Exception ex) {
System.out.println(ex);
}
In this example, it is assumed that image is in src/resources/ folder.
I have done it by the following way
Like the following image. See for more information.
You may take a look at intellij code folding shortcuts.
For Windows/Linux do: Ctrl+Shift+-
For mac use Command+Shift+-
To unfold again do Ctrl+Shift++ or Command+Shift++ respectivley.
I didn't find this solution here. It removes all of it using the cowplot package:
library(cowplot)
p + theme_nothing() +
theme(legend.position="none") +
scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
labs(x = NULL, y = NULL)
Just noticed that the same thing can be accomplished using theme.void() like this:
p + theme_void() +
theme(legend.position="none") +
scale_x_continuous(expand=c(0,0)) +
scale_y_continuous(expand=c(0,0)) +
labs(x = NULL, y = NULL)
If you have tried brew install maven
and were greeted with missing gcc compiler and some other dependencies, an easier approach is to install sdkman
and then run
sdk install maven
(or refer to the latest documentation for the right command)
sdkman is probably over-qualified for the job, but if you deal with multiple versions of SDKs, it's a pretty nice tool to have in general.

Not exactly a dark secret, but I like to put the following mapping into my .vimrc file, so I can hit "-" (minus) anytime to open the file explorer to show files adjacent to the one I just edit. In the file explorer, I can hit another "-" to move up one directory, providing seamless browsing of a complex directory structures (like the ones used by the MVC frameworks nowadays):
map - :Explore<cr>
These may be also useful for somebody. I like to scroll the screen and advance the cursor at the same time:
map <c-j> j<c-e>
map <c-k> k<c-y>
Tab navigation - I love tabs and I need to move easily between them:
map <c-l> :tabnext<enter>
map <c-h> :tabprevious<enter>
Only on Mac OS X: Safari-like tab navigation:
map <S-D-Right> :tabnext<cr>
map <S-D-Left> :tabprevious<cr>
Define an interface, and implement it in the class that will receive the callback.
Have attention to the multi-threading in your case.
Code example from http://cleancodedevelopment-qualityseal.blogspot.com.br/2012/10/understanding-callbacks-with-java.html
interface CallBack { //declare an interface with the callback methods, so you can use on more than one class and just refer to the interface
void methodToCallBack();
}
class CallBackImpl implements CallBack { //class that implements the method to callback defined in the interface
public void methodToCallBack() {
System.out.println("I've been called back");
}
}
class Caller {
public void register(CallBack callback) {
callback.methodToCallBack();
}
public static void main(String[] args) {
Caller caller = new Caller();
CallBack callBack = new CallBackImpl(); //because of the interface, the type is Callback even thought the new instance is the CallBackImpl class. This alows to pass different types of classes that have the implementation of CallBack interface
caller.register(callBack);
}
}
In your case, apart from multi-threading you could do like this:
interface ServerInterface {
void newSeverConnection(Socket socket);
}
public class Server implements ServerInterface {
public Server(int _address) {
System.out.println("Starting Server...");
serverConnectionHandler = new ServerConnections(_address, this);
workers.execute(serverConnectionHandler);
System.out.println("Do something else...");
}
void newServerConnection(Socket socket) {
System.out.println("A function of my child class was called.");
}
}
public class ServerConnections implements Runnable {
private ServerInterface serverInterface;
public ServerConnections(int _serverPort, ServerInterface _serverInterface) {
serverPort = _serverPort;
serverInterface = _serverInterface;
}
@Override
public void run() {
System.out.println("Starting Server Thread...");
if (serverInterface == null) {
System.out.println("Server Thread error: callback null");
}
try {
mainSocket = new ServerSocket(serverPort);
while (true) {
serverInterface.newServerConnection(mainSocket.accept());
}
} catch (IOException ex) {
Logger.getLogger(Server.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
Multi-threading
Remember this does not handle multi-threading, this is another topic and can have various solutions depending on the project.
The observer-pattern
The observer-pattern does nearly this, the major difference is the use of an ArrayList
for adding more than one listener. Where this is not needed, you get better performance with one reference.
Specific actions you can do from SQL client and you don't need to restart anything:
SET GLOBAL log = 'ON';
FLUSH LOGS;
At first, you need to convert time span to DateTime structure:
var dt = new DateTime(2000, 12, 1, timeSpan.Hours, timeSpan.Minutes, timeSpan.Seconds)
Then you need to convert the value to string with Short Time format
var result = dt.ToString("t"); // Convert to string using Short Time format
Just add to @Bert's solution to make it more clear:
const routes = [
{ path: '/foo', component: Foo },
{ path: '/bar', component: Bar }
]
const router = new VueRouter({
routes,
linkExactActiveClass: "active" // active class for *exact* links.
})
As one can see, this line should be removed:
linkActiveClass: "active", // active class for non-exact links.
this way, ONLY the current link is hi-lighted. This should apply to most of the cases.

You need to install JMF first (download using this link)
File f = new File("D:/Songs/preview.mp3");
MediaLocator ml = new MediaLocator(f.toURL());
Player p = Manager.createPlayer(ml);
p.start();
don't forget to add JMF jar files
You can also done this by using group by clause
SELECT purchases.address_id, purchases.* FROM "purchases"
WHERE "purchases"."product_id" = 1 GROUP BY address_id,
purchases.purchased_at ORDER purchases.purchased_at DESC
I finally was able to run datepicker directive in angular js , here are pointers
include following JS in order
I added the following
<script src="http://code.jquery.com/jquery-1.10.2.js"></script>
<script src="http://code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"> </script>
in html code
<body ng-app="myApp" ng-controller="myController">
// some other html code
<input type="text" ng-model="date" mydatepicker />
<br/>
{{ date }}
//some other html code
</body>
in the js , make sure you code for the directive first and after that add the code for controller , else it will cause issues.
date picker directive :
var app = angular.module('myApp',[]);
app.directive('mydatepicker', function () {
return {
restrict: 'A',
require: 'ngModel',
link: function (scope, element, attrs, ngModelCtrl) {
element.datepicker({
dateFormat: 'DD, d MM, yy',
onSelect: function (date) {
scope.date = date;
scope.$apply();
}
});
}
};
});
directive code referred from above answers.
After this directive , write the controller
app.controller('myController',function($scope){
//controller code
};
TRY THIS INSTEAD in angular js
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
along with jquery.js and jquery-ui.js
we can implement angular js datepicker as
<input type="date" ng-model="date" name="DOB">
This gives the built in datepicker and date is set in ng-model and can be used for further processing and validation.
Found this after lot of successful headbanging with previous approach. :)
I had the same problem before, and fixed that, the steps could be found on this Fixing error "GLIBCXX_3.4.15" on matlab
When you establish a connection for a transaction, you acquire a lock before performing the transaction. If not able to acquire the lock, then you try for sometime. If lock is still not obtainable, then lock wait time exceeded error is thrown. Why you will not able to acquire a lock is that you are not closing the connection. So, when you are trying to get a lock second time, you will not be able to acquire the lock as your previous connection is still unclosed and holding the lock.
Solution: close the connection or setAutoCommit(true)
(according to your design) to release the lock.
Here are the steps:
It seems you are checking the .project file into the source repository. I would suggest not checking in the .project file so users can have their own version of the file. Also, if you use the subclipse plugin it allows you to check out and configure a source folder as a java project. This process creates the correct .project for you(with the java nature),
Also remember, the same idea applies to variables. You will come across terms like static, member, instance, class and so on when talking about variables the same as you would for methods/functions.
It seems the common term in the Obj-C community is ivar for instance variable, but I am not an Obj-C guy, yet.
If some one needs cryptographic-strong UUID, there is solution for that as well.
https://www.npmjs.com/package/generate-safe-id
npm install generate-safe-id
Why not UUIDs?
Random UUIDs (UUIDv4) do not have enough entropy to be universally unique (ironic, eh?). Random UUIDs have only 122 bits of entropy, which suggests that a duplicate will occur after only 2^61 IDs. Additionally, some UUIDv4 implementations do not use a cryptographically strong random number generator.
This library generates 240-bit IDs using the Node.js crypto RNG, suggesting the first duplicate will occur after generating 2^120 IDs. Based on the current energy production of the human race, this threshold will be impossible to cross for the foreseeable future.
var generateSafeId = require('generate-safe-id');
var id = generateSafeId();
// id == "zVPkWyvgRW-7pSk0iRzEhdnPcnWfMRi-ZcaPxrHA"
First google search yielded me this answer. So I thought of updating this with newer version of attach, detach.
Create database dbname
On
(
Filename= 'path where you copied files',
Filename ='path where you copied log'
)
For attach;
Further,if your database is cleanly shutdown(there are no active transactions while database was shutdown) and you dont have log file,you can use below method,SQL server will create a new transaction log file..
Create database dbname
On
(
Filename= 'path where you copied files'
)
For attach;
if you don't specify transaction log file,SQL will try to look in the default path and will try to use it irrespective of whether database was cleanly shutdown or not..
Here is what MSDN has to say about this..
If a read-write database has a single log file and you do not specify a new location for the log file, the attach operation looks in the old location for the file. If it is found, the old log file is used, regardless of whether the database was shut down cleanly. However, if the old log file is not found and if the database was shut down cleanly and has no active log chain, the attach operation attempts to build a new log file for the database.
There are some restrictions with this approach and some side affects too..
1.attach-and-detach operations both disable cross-database ownership chaining for the database
2.Database trustworthy is set to off
3.Detaching a read-only database loses information about the differential bases of differential backups.
Most importantly..you can't attach a database with recent versions to an earlier version

you make the use of the HTML Helper and have
@using(Html.BeginForm())
{
Username: <input type="text" name="username" /> <br />
Password: <input type="text" name="password" /> <br />
<input type="submit" value="Login">
<input type="submit" value="Create Account"/>
}
or use the Url helper
<form method="post" action="@Url.Action("MyAction", "MyController")" >
Html.BeginForm
has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:
@using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
< ... >
}
If you don't specify any arguments, the Html.BeginForm()
will create a POST
form that points to your current controller and current action. As an example, let's say you have a controller called Posts
and an action called Delete
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
return View(model);
}
[HttpPost]
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
if(model != null)
db.DeletePost(id);
return RedirectToView("Index");
}
and your html page would be something like:
<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>@Model.Title</strong> will be deleted.</p>
@using(Html.BeginForm())
{
<input type="submit" class="btn btn-danger" value="Delete Post"/>
<text>or</text>
@Url.ActionLink("go to list", "Index")
}

make_working_directory_be_not_winpython.bat
You need to edit the following line in it:
echo WINPYWORKDIR = %%HOMEDRIVE%%%%HOMEPATH%%\Documents\WinPython%%WINPYVER%%\Notebooks>>"%winpython_ini%"
replacing the Documents\WinPython%%WINPYVER%%\Notebooks
part with your folder address.
Notice that the %%HOMEDRIVE%%%%HOMEPATH%%\
part will identify the root and user folders (i.e. C:\Users\your_name\
) which will allow you to point different WinPython installations on separate computers to the same cloud storage folder (e.g. OneDrive), accessing and working with the same files from different machines. I find that very useful.
React may batch updates, and therefore the correct approach is to provide setState with a function that performs the update.
For the React update addon, the following will reliably work:
this.setState( state => update(state, {array: {$push: [4]}}) );
or for concat():
this.setState( state => ({
array: state.array.concat([4])
}));
The following shows what https://jsbin.com/mofekakuqi/7/edit?js,output as an example of what happens if you get it wrong.
The setTimeout() invocation correctly adds three items because React will not batch updates within a setTimeout callback (see https://groups.google.com/d/msg/reactjs/G6pljvpTGX0/0ihYw2zK9dEJ).
The buggy onClick will only add "Third", but the fixed one, will add F, S and T as expected.
class List extends React.Component {
constructor(props) {
super(props);
this.state = {
array: []
}
setTimeout(this.addSome, 500);
}
addSome = () => {
this.setState(
update(this.state, {array: {$push: ["First"]}}));
this.setState(
update(this.state, {array: {$push: ["Second"]}}));
this.setState(
update(this.state, {array: {$push: ["Third"]}}));
};
addSomeFixed = () => {
this.setState( state =>
update(state, {array: {$push: ["F"]}}));
this.setState( state =>
update(state, {array: {$push: ["S"]}}));
this.setState( state =>
update(state, {array: {$push: ["T"]}}));
};
render() {
const list = this.state.array.map((item, i) => {
return <li key={i}>{item}</li>
});
console.log(this.state);
return (
<div className='list'>
<button onClick={this.addSome}>add three</button>
<button onClick={this.addSomeFixed}>add three (fixed)</button>
<ul>
{list}
</ul>
</div>
);
}
};
ReactDOM.render(<List />, document.getElementById('app'));
If you don't care about loading the file into memory, as of Go 1.16, you can use the os.ReadFile
and bytes.Count
functions.
package main
import (
"log"
"os"
"bytes"
)
func main() {
data, err := os.ReadFile("input.txt")
if err != nil {
log.Fatal(err)
}
n := bytes.Count(data, []byte{'\n'})
fmt.Printf("input.txt has %d lines\n", n)
}
MSSQL uses regular XPath rules as follows:
Since my requirement is override the existing textView get from findViewById(getResources().getIdentifier("xxx", "id", "android"));
, so I can't simply try onDraw()
of other answer.
But I just figure out the correct steps to fixed my problem, here is the final result from Layout Inspector:
Since what I wanted is merely remove the top spaces, so I don't have to choose other font to remove bottom spaces.
Here is the critical code to fixed it:
Typeface mfont = Typeface.createFromAsset(getResources().getAssets(), "fonts/myCustomFont.otf");
myTextView.setTypeface(mfont);
myTextView.setPadding(0, 0, 0, 0);
myTextView.setIncludeFontPadding(false);
The first key is set custom font "fonts/myCustomFont.otf" which has the space on bottom but not on the top, you can easily figure out this by open otf file and click any font in android Studio:
As you can see, the cursor on the bottom has extra spacing but not on the top, so it fixed my problem.
The second key is you can't simply skip any of the code, otherwise it might not works. That's the reason you can found some people comment that an answer is working and some other people comment that it's not working.
Let's illustrated what will happen if I remove one of them.
Without setTypeface(mfont);
:
Without setPadding(0, 0, 0, 0);
:
Without setIncludeFontPadding(false);
:
Without 3 of them (i.e. the original):
This works for me in Django 1.8

You could also add an offset if you want to use negative indexes:
uint8_t l_matrix[10][20];
uint8_t (*matrix_ptr)[20] = l_matrix+5;
matrix_ptr[-4][1]=7;
If your compiler gives an error or warning you could use:
uint8_t (*matrix_ptr)[20] = (uint8_t (*)[20]) l_matrix;
Create a function and copy the code using winsock which is mentioned already by Software_Developer.
For Instance:
#ifdef _WIN32
// this is required only for windows
if (WSAStartup(MAKEWORD(2,2), &wsaData) != 0)
{
//...
}
#endif
winsock code here
#ifdef _WIN32
WSACleanup();
#endif
The difference between the two is really simple!.
<context:annotation-config />
Enables you to use annotations that are restricted to wiring up properties and constructors only of beans!.
Where as
<context:component-scan base-package="org.package"/>
Enables everything that <context:annotation-config />
can do, with addition of using stereotypes eg.. @Component
, @Service
, @Repository
. So you can wire entire beans and not just restricted to constructors or properties!.
To ignore untracked files just go to .git/info/exclude. Exclude is a file with a list of ignored extensions or files.
As @AndreasPaulsson suggested, we need to configure it. I am doing the configuration in AssemblyInfo
file. I specify the configuration file name
here.
// Log4Net Configuration.
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
I think this is enough to get you on a nice path:
Sub a()
Dim btn As Button
Application.ScreenUpdating = False
ActiveSheet.Buttons.Delete
Dim t As Range
For i = 2 To 6 Step 2
Set t = ActiveSheet.Range(Cells(i, 3), Cells(i, 3))
Set btn = ActiveSheet.Buttons.Add(t.Left, t.Top, t.Width, t.Height)
With btn
.OnAction = "btnS"
.Caption = "Btn " & i
.Name = "Btn" & i
End With
Next i
Application.ScreenUpdating = True
End Sub
Sub btnS()
MsgBox Application.Caller
End Sub
It creates the buttons and binds them to butnS(). In the btnS() sub, you should show your dialog, etc.
class foo(object):
def __str__(self):

SASS has a built-in rgba() function to evaluate values.
rgba($color, $alpha)
E.g.
rgba(#00aaff, 0.5) => rgba(0, 170, 255, 0.5)
An example using your own variables:
$my-color: #00aaff;
$my-opacity: 0.5;
.my-element {
color: rgba($my-color, $my-opacity);
}
Outputs:
.my-element {
color: rgba(0, 170, 255, 0.5);
}
NPP+ v7.9.1 with the latest version of XMLTools can't format exported VBA code from Office 2016/2019 Word. It puts all the code on the same line since it strips the CRLF out. Moreover, when you enable "auto validation" it errors out on the first VBA line that is, Attribute VB_Name = "The VBA module name". So any of the xml tool validations apparently can't be used for VBA validation.
you can do it by using Sheetsee.js and tabletop.js
Performance wise String concatenation using '+' is costlier because it has to make a whole new copy of String since Strings are immutable in java. This plays particular role if concatenation is very frequent, eg: inside a loop. Following is what my IDEA suggests when I attempt to do such a thing:
General Rules:
Here is a nice Jon Skeet blog around this topic.
Let's illustrate what's happening here:
Python 3.1.2 (r312:79147, Sep 27 2010, 09:45:41)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> class Foo:
... def __init__(self, x=[]):
... x.append(1)
...
>>> Foo.__init__.__defaults__
([],)
>>> f = Foo()
>>> Foo.__init__.__defaults__
([1],)
>>> f2 = Foo()
>>> Foo.__init__.__defaults__
([1, 1],)
You can see that the default arguments are stored in a tuple which is an attribute of the function in question. This actually has nothing to do with the class in question and goes for any function. In python 2, the attribute will be func.func_defaults
.
As other posters have pointed out, you probably want to use None
as a sentinel value and give each instance it's own list.
Please use below code
package com.myjava.string;
import java.util.StringTokenizer;
public class MyStrRemoveMultSpaces {
public static void main(String a[]){
String str = "String With Multiple Spaces";
StringTokenizer st = new StringTokenizer(str, " ");
StringBuffer sb = new StringBuffer();
while(st.hasMoreElements()){
sb.append(st.nextElement()).append(" ");
}
System.out.println(sb.toString().trim());
}
}
It uses the normal trash bin of your system. So you can grab it our of there.
In Windows you find it in the explorer, in Linux it is as well in Konquerer / Nemo / ...
If you start to do something like this, then I would say it starts to get a bit strange and you're better off moving it to a seperate method that returns
a result upon the matchedCondition.
boolean matched = false;
for(int i = 0; i < 10; i++) {
for(int j = 0; j < 10; j++) {
if(matchedCondition) {
matched = true;
break;
}
}
if(matched) {
break;
}
}
To elaborate on how to clean up the above code, you can refactor, moving the code to a function that returns
instead of using breaks
. This is in general, better dealing with complex/messy breaks
.
public boolean matches()
for(int i = 0; i < 10; i++) {
for(int j = 0; j < 10; j++) {
if(matchedCondition) {
return true;
}
}
}
return false;
}
However for something simple like my below example. By all means use break
!
for(int i = 0; i < 10; i++) {
if(wereDoneHere()) { // we're done, break.
break;
}
}
And changing the conditions, in the above case i
, and j
's value, you would just make the code really hard to read. Also there could be a case where the upper limits (10 in the example) are variables so then it would be even harder to guess what value to set it to in order to exit the loop. You could of course just set i
and j
to Integer.MAX_VALUE, but I think you can see this starts to get messy very quickly. :)
Try this. It's works for me well.
function clicked(item) {
alert($(item).attr("id"));
}

Try this library:
https://github.com/avast/android-styled-dialogs
It's based on DialogFragments
instead of AlertDialogs
(like the one from @afollestad). The main advantage: Dialogs don't dismiss after rotation and callbacks still work.
var str = "{'a':1}";
str = str.replace(/'/g, '"')
obj = JSON.parse(str);
console.log(obj);
This solved the problem for me.
There's no need to mess with your PYTHONPATH
or sys.path
here.
To properly use absolute imports in a package you should include the "root" packagename as well, e.g.:
from dirFoo.dirFoo1.foo1 import Foo1
from dirFoo.dirFoo2.foo2 import Foo2
Or you can use relative imports:
from .dirfoo1.foo1 import Foo1
from .dirfoo2.foo2 import Foo2
JavaScript is single threaded and has a synchronous execution model. Single threaded means that one command is being executed at a time. Synchronous means one at a time i.e. one line of code is being executed at time in order the code appears. So in JavaScript one thing is happening at a time.
Execution Context
The JavaScript engine interacts with other engines in the browser. In the JavaScript execution stack there is global context at the bottom and then when we invoke functions the JavaScript engine creates new execution contexts for respective functions. When the called function exits its execution context is popped from the stack, and then next execution context is popped and so on...
For example
function abc()
{
console.log('abc');
}
function xyz()
{
abc()
console.log('xyz');
}
var one = 1;
xyz();
In the above code a global execution context will be created and in this context var one
will be stored and its value will be 1... when the xyz() invocation is called then a new execution context will be created and if we had defined any variable in xyz function those variables would be stored in the execution context of xyz(). In the xyz function we invoke abc() and then the abc() execution context is created and put on the execution stack... Now when abc() finishes its context is popped from stack, then the xyz() context is popped from stack and then global context will be popped...
Now about asynchronous callbacks; asynchronous means more than one at a time.
Just like the execution stack there is the Event Queue. When we want to be notified about some event in the JavaScript engine we can listen to that event, and that event is placed on the queue. For example an Ajax request event, or HTTP request event.
Whenever the execution stack is empty, like shown in above code example, the JavaScript engine periodically looks at the event queue and sees if there is any event to be notified about. For example in the queue there were two events, an ajax request and a HTTP request. It also looks to see if there is a function which needs to be run on that event trigger... So the JavaScript engine is notified about the event and knows the respective function to execute on that event... So the JavaScript engine invokes the handler function, in the example case, e.g. AjaxHandler() will be invoked and like always when a function is invoked its execution context is placed on the execution context and now the function execution finishes and the event ajax request is also removed from the event queue... When AjaxHandler() finishes the execution stack is empty so the engine again looks at the event queue and runs the event handler function of HTTP request which was next in queue. It is important to remember that the event queue is processed only when execution stack is empty.
For example see the code below explaining the execution stack and event queue handling by Javascript engine.
function waitfunction() {
var a = 5000 + new Date().getTime();
while (new Date() < a){}
console.log('waitfunction() context will be popped after this line');
}
function clickHandler() {
console.log('click event handler...');
}
document.addEventListener('click', clickHandler);
waitfunction(); //a new context for this function is created and placed on the execution stack
console.log('global context will be popped after this line');
And
<html>
<head>
</head>
<body>
<script src="program.js"></script>
</body>
</html>
Now run the webpage and click on the page, and see the output on console. The output will be
waitfunction() context will be popped after this line
global context will be emptied after this line
click event handler...
The JavaScript engine is running the code synchronously as explained in the execution context portion, the browser is asynchronously putting things in event queue. So the functions which take a very long time to complete can interrupt event handling. Things happening in a browser like events are handled this way by JavaScript, if there is a listener supposed to run, the engine will run it when the execution stack is empty. And events are processed in the order they happen, so the asynchronous part is about what is happening outside the engine i.e. what should the engine do when those outside events happen.
So JavaScript is always synchronous.
Given sheet 2:
ColumnA
-------
apple
orange
You can flag the rows in sheet 1 where a value exists in sheet 2:
ColumnA ColumnB
------- --------------
pear =IF(ISERROR(VLOOKUP(A1,Sheet2!A:A,1,FALSE)),"Keep","Delete")
apple =IF(ISERROR(VLOOKUP(A2,Sheet2!A:A,1,FALSE)),"Keep","Delete")
cherry =IF(ISERROR(VLOOKUP(A3,Sheet2!A:A,1,FALSE)),"Keep","Delete")
orange =IF(ISERROR(VLOOKUP(A4,Sheet2!A:A,1,FALSE)),"Keep","Delete")
plum =IF(ISERROR(VLOOKUP(A5,Sheet2!A:A,1,FALSE)),"Keep","Delete")
The resulting data looks like this:
ColumnA ColumnB
------- --------------
pear Keep
apple Delete
cherry Keep
orange Delete
plum Keep
You can then easily filter or sort sheet 1 and delete the rows flagged with 'Delete'.
Swift 2.0 (Single line):
String(nameOfString.characters.prefix(1)).uppercaseString + String(nameOfString.characters.dropFirst())
I suggest you use TO_CHAR()
when converting to string. In order to do that, you need to build a date first.
SELECT TO_CHAR(TO_DATE(DAY||'-'||MONTH||'-'||YEAR, 'dd-mm-yyyy'), 'dd-mm-yyyy') AS FORMATTED_DATE
FROM
(SELECT EXTRACT( DAY FROM
(SELECT TO_DATE('1/21/2000', 'mm/dd/yyyy')
FROM DUAL
)) AS DAY, TO_NUMBER(EXTRACT( MONTH FROM
(SELECT TO_DATE('1/21/2000', 'mm/dd/yyyy') FROM DUAL
)), 09) AS MONTH, EXTRACT(YEAR FROM
(SELECT TO_DATE('1/21/2000', 'mm/dd/yyyy') FROM DUAL
)) AS YEAR
FROM DUAL
);

I had this error; it happened somewhat spontaneously, and the page would halt in the browser in the middle of an HTML tag (not a section of code). It was baffling!
Turns out, I let a variable go out of scope and the garbage collector swept it away and then I tried to use it. Thus the seemingly-random timing.
To give a more concrete example... Inside a method, I had something like:
Foo[] foos = new Foo[20];
// fill up the "foos" array...
return Arrays.asList(foos); // this returns type List<Foo>
Now in my JSP page, I called that method and used the List object returned by it. The List object is backed by that "foos" array; but, the array went out of scope when I returned from the method (since it is a local variable). So shortly after returning, the garbage collector swept away the "foos" array, and my access to the List caused a NullPointerException since its underlying array was now wiped away.
I actually wondered, as I wrote the above method, whether that would happen.
The even deeper underlying problem was premature optimization. I wanted a list, but I knew I would have exactly 20 elements, so I figured I'd try to be more efficient than new ArrayList<Foo>(20)
which only sets an initial size of 20 but can possibly be less efficient than the method I used. So of course, to fix it, I just created my ArrayList, filled it up, and returned it. No more strange error.

You can try this:
[System.IO.FileInfo]$path = "D:\Server\User\CUST\MEA\Data\In\Files\CORRECTED\CUST_MEAFile.csv"
# Returns name and extension
$path.Name
# Returns just name
$path.BaseName
For portability, you really should do something like this:
public static final String NEW_LINE = System.getProperty("line.separator")
.
.
.
word.contains(NEW_LINE);
unless you're absolutely certain that "\n"
is what you want.
It should be (-###

You can make them appear more "clearly" with a command:
gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )//g'
and you can get rid of flags with -mno-* with:
gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )|( -mno-[^\ ]+)//g'

feel free to play with flex-basis percentage to get more customized space.
In bootstrap 4 use:
<ul class="nav navbar-nav ml-auto">
This will push the navbar to the right. Use mr-auto to push it to the left, this is the default behaviour.

The screenshot was very helpful - the following code will do the job (assuming data is located in column A starting A1):
Sub RemoveRows()
Dim i As Long
i = 1
Do While i <= ThisWorkbook.ActiveSheet.Range("A1").CurrentRegion.Rows.Count
If InStr(1, ThisWorkbook.ActiveSheet.Cells(i, 1).Text, "-", vbTextCompare) > 0 Then
ThisWorkbook.ActiveSheet.Cells(i, 1).EntireRow.Delete
Else
i = i + 1
End If
Loop
End Sub

If you are writing a web app or single page application (SPA) where routing takes place in the app/browser rather than a round-trip to the server, you can do the following:
window.history.pushState({ prevUrl: window.location.href }, null, "/new/path/in/your/app")
Then, in your new route, you can do the following to retrieve the previous URL:
window.history.state.prevUrl // your previous url
