In 2 out of 2 occasions of reports IE8 crashing I got it fixed with removing the background-image from the body element in css. Background-colors are no problem and also putting the same background-image on any other element(for example html) is no problem.
The crash only happened in an actual IE8 in IE8 mode. So you can't test this in IE9 compatibility mode and strangely it can indeed be 'fixed' by forcing IE8 to go into IE7 mode.
Pure Virtual Functions are mostly used to define:
a) abstract classes
These are base classes where you have to derive from them and then implement the pure virtual functions.
b) interfaces
These are 'empty' classes where all functions are pure virtual and hence you have to derive and then implement all of the functions.
Pure virtual functions are actually functions which have no implementation in base class and have to be implemented in derived class.
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. :)
Visual Studio has got now integrated support for range checking and type checking :-
Try this :- For RANGE CHECKING Before validating/checking for a particular range of numbers Switch on to design view from markup view .Then :-
View>Toolbox>Validation
Now Drag on RangeValidator to your design page where you want to show the error message(ofcourse if user is inputting out of range value) now click on your RangeValidator control . Right click and select properties . In the Properties window (It is usually opened below solution bar) select on ERROR MESSAGE . Write :-
Number must be in range.
Now select on Control to validate and select your TextboxID (or write it anyways) from the drop down.Locate Type in the property bar itself and select down Integer.
Just above it you will find maximum and minimum value .Type in your desired number .
For Type checking (without any Range)
Before validating/checking for a particular range of numbers Switch on to design view from markup view .Then :-
View>Toolbox>Validation
Now Drag on CompareValidator to your design page where you want to show the error message(ofcourse if user is inputting some text in it). now click on your CompareValidator control . Right click and select properties . In the Properties window (It is usually opened below solution bar) select on ERROR MESSAGE . Write:-
Value must be a number .
Now locate ControltoValidate option and write your controlID name in it(alternatively you can also select from drop down).Locate the Operator option and write DataTypeCheck(alternatively you can also select from drop down)in it .Again locate the Type option and write Integer in it .
That's sit.
Alternatively you can write the following code in your aspx page :- <%--to validate without any range--%>
You are using a wrong overload of the Html.ActionLink
helper. What you think is routeValues
is actually htmlAttributes
! Just look at the generated HTML, you will see that this anchor's href property doesn't look as you expect it to look.
Here's what you are using:
@Html.ActionLink(
"Reply", // linkText
"BlogReplyCommentAdd", // actionName
"Blog", // routeValues
new { // htmlAttributes
blogPostId = blogPostId,
replyblogPostmodel = Model,
captchaValid = Model.AddNewComment.DisplayCaptcha
}
)
and here's what you should use:
@Html.ActionLink(
"Reply", // linkText
"BlogReplyCommentAdd", // actionName
"Blog", // controllerName
new { // routeValues
blogPostId = blogPostId,
replyblogPostmodel = Model,
captchaValid = Model.AddNewComment.DisplayCaptcha
},
null // htmlAttributes
)
Also there's another very serious issue with your code. The following routeValue:
replyblogPostmodel = Model
You cannot possibly pass complex objects like this in an ActionLink. So get rid of it and also remove the BlogPostModel
parameter from your controller action. You should use the blogPostId
parameter to retrieve the model from wherever this model is persisted, or if you prefer from wherever you retrieved the model in the GET action:
public ActionResult BlogReplyCommentAdd(int blogPostId, bool captchaValid)
{
BlogPostModel model = repository.Get(blogPostId);
...
}
As far as your initial problem is concerned with the wrong overload I would recommend you writing your helpers using named parameters:
@Html.ActionLink(
linkText: "Reply",
actionName: "BlogReplyCommentAdd",
controllerName: "Blog",
routeValues: new {
blogPostId = blogPostId,
captchaValid = Model.AddNewComment.DisplayCaptcha
},
htmlAttributes: null
)
Now not only that your code is more readable but you will never have confusion between the gazillions of overloads that Microsoft made for those helpers.
For Ajax calls or XML / JSON responses, where you don't want to mess with the body, you need to send logs via HTTP headers, then add them to the console with a web extension. This is how FirePHP (no longer available) and QuantumPHP (a fork of ChromePHP) do it in Firefox.
If you have the patience, x-debug is a better option - you get deeper insight into PHP, with the ability to pause your script, see what is going on, then resume the script.
i wouldn't do it this way
I'd use name arrays in the form elements
so i'd get the layout
$_POST['field'][0]['name'] = 'value';
$_POST['field'][0]['price'] = 'value';
$_POST['field'][1]['name'] = 'value';
$_POST['field'][1]['price'] = 'value';
then you could do an array slice to get the amount you need
According to Python3 documentation,python when divided by integer,will generate float despite expected to be integer.
For exclusively printing integer,use floor division method
.
Floor division is rounding off zero and removing decimal point. Represented by //
Hence,instead of 2/2 ,use 2//2
You can also import division from __future__
irrespective of using python2 or python3.
Hope it helps!
Why don't you style it out:
<canvas id="canvas" width="800" height="600" style="background: url('./images/image.jpg')">
Your browser does not support the canvas element.

Building on @IllidanS4 's answer, I have created a template class that allows virtually any member function with predefined arguments and class instance to be passed by reference for later calling.
template<class RET, class... RArgs> class Callback_t {
public:
virtual RET call(RArgs&&... rargs) = 0;
//virtual RET call() = 0;
};
template<class T, class RET, class... RArgs> class CallbackCalltimeArgs : public Callback_t<RET, RArgs...> {
public:
T * owner;
RET(T::*x)(RArgs...);
RET call(RArgs&&... rargs) {
return (*owner.*(x))(std::forward<RArgs>(rargs)...);
};
CallbackCalltimeArgs(T* t, RET(T::*x)(RArgs...)) : owner(t), x(x) {}
};
template<class T, class RET, class... Args> class CallbackCreattimeArgs : public Callback_t<RET> {
public:
T* owner;
RET(T::*x)(Args...);
RET call() {
return (*owner.*(x))(std::get<Args&&>(args)...);
};
std::tuple<Args&&...> args;
CallbackCreattimeArgs(T* t, RET(T::*x)(Args...), Args&&... args) : owner(t), x(x),
args(std::tuple<Args&&...>(std::forward<Args>(args)...)) {}
};
Test / example:
class container {
public:
static void printFrom(container* c) { c->print(); };
container(int data) : data(data) {};
~container() {};
void print() { printf("%d\n", data); };
void printTo(FILE* f) { fprintf(f, "%d\n", data); };
void printWith(int arg) { printf("%d:%d\n", data, arg); };
private:
int data;
};
int main() {
container c1(1), c2(20);
CallbackCreattimeArgs<container, void> f1(&c1, &container::print);
Callback_t<void>* fp1 = &f1;
fp1->call();//1
CallbackCreattimeArgs<container, void, FILE*> f2(&c2, &container::printTo, stdout);
Callback_t<void>* fp2 = &f2;
fp2->call();//20
CallbackCalltimeArgs<container, void, int> f3(&c2, &container::printWith);
Callback_t<void, int>* fp3 = &f3;
fp3->call(15);//20:15
}
Obviously, this will only work if the given arguments and owner class are still valid. As far as readability... please forgive me.
Edit: removed unnecessary malloc by making the tuple normal storage. Added inherited type for the reference. Added option to provide all arguments at calltime instead. Now working on having both....
Edit 2: As promised, both. Only restriction (that I see) is that the predefined arguments must come before the runtime supplied arguments in the callback function. Thanks to @Chipster for some help with gcc compliance. This works on gcc on ubuntu and visual studio on windows.

updateTypeahead(this)
will not pass DOM element to the function updateTypeahead(this)
. Here this
will refer to the scope. If you want to access the DOM element use updateTypeahead($event)
. In the callback function you can get the DOM element by event.target
.
Please Note : ng-change function doesn't allow to pass $event as variable.
Global variables that are defined outside of any method or closure can be scope restricted by using the private keyword.

You can use reflect.DeepEqual, or you can implement your own function (which performance wise would be better than using reflection):
http://play.golang.org/p/CPdfsYGNy_
m1 := map[string]int{
"a":1,
"b":2,
}
m2 := map[string]int{
"a":1,
"b":2,
}
fmt.Println(reflect.DeepEqual(m1, m2))
With rlang 0.4.0
we have curly-curly operators ({{}}
) which makes this very easy.

multipetal <- function(df, n) {
varname <- paste("petal", n , sep=".")
mutate(df, {{varname}} := Petal.Width * n)
}
multipetal(iris1, 4)

We can also pass quoted/unquoted variable names to be assigned as column names.

I have a very well working solution for tables of max-width: 100%
.
Just use word-break: break-all;
for the table cells (except heading cells) to break all long text into several lines:
<!DOCTYPE html>
<html>
<head>
<style>
table {
max-width: 100%;
}
table td {
word-break: break-all;
}
</style>
</head>
<body>
<table border="1">
<tr>
<th><strong>Input</strong></th>
<th><strong>Output</strong></th>
</tr>
<tr>
<td>some text</td>
<td>12b6459fc6b4cabb4b1990be1a78e4dc5fa79c3a0fe9aa9f0386d673cfb762171a4aaa363b8dac4c33e0ad23e4830888</td>

I'm going to answer my own question.
Therefore, the following works for me
$qb->select('c')
->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
->where('c.username = :username');
or
$qb->select('c')
->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
->where('c.username = :username');
Use this:
static int RandomNumber(int min, int max)
{
Random random = new Random(); return random.Next(min, max);
}
This is example for you to modify and use in your application.
The easiest way is probably to check the PATH environment variable of the process that is connecting to the database. Most likely the tnsnames.ora file is in first Oracle bin directory in path..\network\admin. TNS_ADMIN environment variable or value in registry (for the current Oracle home) may override this.
Using filemon like suggested by others will also do the trick.
The reason to make an App with no activity or service could be making a Homescreen Widget app that doesn't need to be started.
Once you start a project don't create any activities. After you created the project just hit run. Android studio will say No default activity found
.
Click Edit Configuration (From the Run menu) and in the Launch option part set the Launch value to Nothing.
Then click ok and run the App.
(Since there is no launcher activity, No app will be show in the Apps menu.).
SqlConnection con = new SqlConnection("Data Source=DShp;Initial Catalog=abc;Integrated Security=True");

If you can get away with using Guava it is by far the simplest way to do it, and you don't have to reinvent the wheel:
final HashCode hashCode = Hashing.sha1().hashString(yourValue, Charset.defaultCharset());
You can then take the hashed value and get it as a byte[]
, as an int
, or as a long
.
No wrapping in a try catch, no shenanigans. And if you decide you want to use something other than SHA-1, Guava also supports sha256, sha 512, and a few I had never even heard about like adler32 and murmur3.
What you are using is called a list comprehension in Python, not an inline for-loop (even though it is similar to one). You would write your loop as a list comprehension like so:
p = [q.index(v) if v in q else 99999 for v in vm]
When using a list comprehension, you do not call list.append
because the list is being constructed from the comprehension itself. Each item in the list will be what is returned by the expression on the left of the for
keyword, which in this case is q.index(v) if v in q else 99999
. Incidentially, if you do use list.append
inside a comprehension, then you will get a list of None
values because that is what the append
method always returns.
This comment syntax should work for you:

I went with the HTML5 local storage solution... All my links call a function which sets this before changing window.location:
localStorage.topper = document.body.scrollTop;
and each page has this in the body's onLoad:
if(localStorage.topper > 0){
window.scrollTo(0,localStorage.topper);
}
It's because you're calling doGet()
without actually implementing doGet()
. It's the default implementation of doGet() that throws the error saying the method is not supported.
Nope.
While in debug configuration there is a DEBUG
defined constant (automatically defined by Visual Studio) while there is no such constant defined for release mode. Check your project settings under build.
Selecting [Define DEBUG constant] under Project -> Build is like including #define DEBUG at the beginning of every file.
If you want to define a RELEASE constant for the release configuration go to:
var val = (string === "true");
The question is old, but maybe, somebody need an actual answer.
In the QGIS 3.4 you can get the value from the QComboBox

It depends on what you're wanting to use it for. If you're just trying to save it, you should use pickle
(or, if you’re using CPython 2.x, cPickle
, which is faster).
>>> import pickle
>>> pickle.dumps({'foo': 'bar'})
b'\x80\x03}q\x00X\x03\x00\x00\x00fooq\x01X\x03\x00\x00\x00barq\x02s.'
>>> pickle.loads(_)
{'foo': 'bar'}
If you want it to be readable, you could use json
:
>>> import json
>>> json.dumps({'foo': 'bar'})
'{"foo": "bar"}'
>>> json.loads(_)
{'foo': 'bar'}
json
is, however, very limited in what it will support, while pickle
can be used for arbitrary objects (if it doesn't work automatically, the class can define __getstate__
to specify precisely how it should be pickled).
>>> pickle.dumps(object())
b'\x80\x03cbuiltins\nobject\nq\x00)\x81q\x01.'
>>> json.dumps(object())
Traceback (most recent call last):
...
TypeError: <object object at 0x7fa0348230c0> is not JSON serializable
I would avoid using component state since this could be difficult to manage and prone to issues that can be difficult to troubleshoot.
You should use either cookies
or localStorage
for persisting a user's session data. You can also use a closure as a wrapper around your cookie
or localStorage
data.
Here is a simple example of a UserProfile
closure that will hold the user's name.
var UserProfile = (function() {
var full_name = "";
var getName = function() {
return full_name; // Or pull this from cookie/localStorage
};
var setName = function(name) {
full_name = name;
// Also set this in cookie/localStorage
};
return {
getName: getName,
setName: setName
}
})();
export default UserProfile;
When a user logs in, you can populate this object with user name, email address etc.
import UserProfile from './UserProfile';
UserProfile.setName("Some Guy");
Then you can get this data from any component in your app when needed.
import UserProfile from './UserProfile';
UserProfile.getName();
Using a closure will keep data outside of the global namespace, and make it is easily accessible from anywhere in your app.

Try javax.net.ssl.keyStorePassword
instead of javax.net.ssl.keyPassword
: the latter isn't mentioned in the JSSE ref guide.
The algorithms you mention should be there by default using the default security providers. NoSuchAlgorithmException
s are often cause by other underlying exceptions (file not found, wrong password, wrong keystore type, ...). It's useful to look at the full stack trace.
You could also use -Djavax.net.debug=ssl
, or at least -Djavax.net.debug=ssl,keymanager
, to get more debugging information, if the information in the stack trace isn't sufficient.

Python does not support method overloading like Java or C++. We may overload the methods, but we can only use the latest defined method.
# First sum method.
# Takes two argument and print their sum
def sum(a, b):
s = a + b
print(s)
# Second sum method
# Takes three argument and print their sum
def sum(a, b, c):
s = a + b + c
print(s)
# Uncommenting the below line shows an error
# sum(4, 5)
# This line will call the second sum method
sum(4, 5, 5)
We need to provide optional arguments or *args in order to provide a different number of arguments on calling.

I just sharing my review about this. I am not surely(100% telling) that above code is not working for me and other guys also but some times I got this issue. Suppose I run the app 10 time then might be got this issue 2 to 3 three time.
I have tried above all the answers but still not solve the issue. I have implemented above all the codes and tested in different api levels (API level 26, 28, 29) and difference mobile (Samsung, Xiaomi, MIUI, Vivo, Moto, One Plus, Huawei, etc ) and getting same below issue.
Context.startForegroundService() did not then call Service.startForeground();
I have read service on google developer web site, some other blog and some stack overflow question and got the idea that this issue will happen when we call startForgroundSerivce()
method but at that time service was not started.
In my case I have stop the service and after immediately start service. Below is the hint.
....//some other code
...// API level and other device auto star service condition is already set
stopService();
startService();
.....//some other code
In this case service is not started due to processing speed and low memory in RAM but startForegroundService()
method is called and fire the exception.
Work for me:
new Handler().postDelayed(()->ContextCompat.startForegroundService(activity, new Intent(activity, ChatService.class)), 500);
I have change code and set 500 milliseconds delay to call startService() method and issue is solved. This is not perfect solution because this way app's performance goes downgrade.
Note:
This is only for Foreground and Background service only. Don't tested when using Bind service.
I am sharing this because only this is the way I have solved this issue.

standard format specifier represents a custom date and time format string that is defined by the DateTimeFormatInfo.SortableDateTimePattern property. The pattern reflects a defined standard (ISO 8601), and the property is read-only. Therefore, it is always the same, regardless of the culture used or the format provider supplied. The custom format string is"yyyy'-'MM'-'dd'T'HH':'mm':'ss"
.When this standard format specifier is used, the formatting or parsing operation always uses the invariant culture.

I know this is a somewhat old thread, but I had this problem too with a c#/WPF app I was creating. The app worked fine on the development machine, but would not start on the test machine. The Application Log in the Event Viewer gave a somewhat nebulous .NET Runtime error of System.IO.DirectoryNotFoundException.
I tried using some debugging software but the app would not stay running long enough to attach the debugger to the process. After banging my head against my desk for a day and looking at many web pages like this one, what I wound up doing to troubleshoot this was to install VS2019 on my test machine. I then dragged the .exe file from its folder (it was deep in the Users[user]\AppData\Apps\2.0... folder) to the open VS2019 instance and went to start it from there. Immediately, it came up with a dialog box giving the exception and the cause.
In my case, when I added an icon to one of the forms, the complete path to the icon was placed into the XAML instead of just the icon name. I had copied the icon file into the project folder, but since the project folder does not exist on the test machine, this was the root cause of the error. I then removed the path from the XAML, leaving just the icon name one, rebuilt the solution and re-published it, and it ran just fine on the test machine now. Of course there are many causes besides what gave me the error, but this method of troubleshooting should hopefully identify the root cause of the error, since the Windows Event Viewer gives a somewhat vague answer.
To summarize, use Visual Studio on the test machine as a debugger of sorts. But, to get it to work right, I had to drag the .exe file into the IDE and Start (run) it from there. I believe this will also work with VS2017 as well as VS2019. Hopefully this helps someone who is still having this issue.
By using NULL
without any quotes.
UPDATE `tablename` SET `fieldName` = NULL;
How about more simply: Select * from tblStudents where [name] = replace(YourName,"'","''")
My first post...
I tried this: change 'tr' for 'td' and you will get all HTMLRowElements into an Array, and using textContent will change from Object into String
var dataArray = [];
var data = table.find('td'); //Get All HTML td elements
// Save important data into new Array
for (var i = 0; i <= data.size() - 1; i = i + 4)
{
dataArray.push(data[i].textContent, data[i + 1].textContent, data[i + 2].textContent);
}
var e = jQuery.Event("keypress");
e.which = 13; //choose the one you want
e.keyCode = 13;
$("#theInputToTest").trigger(e);
If you are using 11G XE with Windows, along with tns listener restart, make sure Windows Event Log service is started.
You can have any length, but of course, there can be a memory issue on the computer if the String input is too long. The output is always 32 characters.
To get the files in the classpath :
Resource resource = new ClassPathResource("countries.xml");
File file = resource.getFile();
To read the file onStartup use @PostConstruct
:
@Configuration
public class ReadFileOnStartUp {
@PostConstruct
public void afterPropertiesSet() throws Exception {
//Gets the XML file under src/main/resources folder
Resource resource = new ClassPathResource("countries.xml");
File file = resource.getFile();
//Logic to read File.
}
}
Here is a Small example for reading an XML File on Spring Boot App startup.
Consider this example for easy understanding.
What does telecommunication companies provide? Broadband, phone line and mobile for instance and you're asked to create an application to offer their products to their customers.
Generally what you'd do here is, creating the products i.e broadband, phone line and mobile are through your Factory Method where you know what properties you have for those products and it's pretty straightforward.
Now, the company wants to offer their customer a bundle of their products i.e broadband, phone line, and mobile altogether, and here comes the Abstract Factory to play.
Abstract Factory is, in other words, are the composition of other factories who are responsible for creating their own products and Abstract Factory knows how to place these products in more meaningful in respect of its own responsibilities.
In this case, the BundleFactory
is the Abstract Factory, BroadbandFactory
, PhonelineFactory
and MobileFactory
are the Factory
. To simplify more, these Factories will have Factory Method to initialise the individual products.
Se the code sample below:
public class BroadbandFactory : IFactory {
public static Broadband CreateStandardInstance() {
// broadband product creation logic goes here
}
}
public class PhonelineFactory : IFactory {
public static Phoneline CreateStandardInstance() {
// phoneline product creation logic goes here
}
}
public class MobileFactory : IFactory {
public static Mobile CreateStandardInstance() {
// mobile product creation logic goes here
}
}
public class BundleFactory : IAbstractFactory {
public static Bundle CreateBundle() {
broadband = BroadbandFactory.CreateStandardInstance();
phoneline = PhonelineFactory.CreateStandardInstance();
mobile = MobileFactory.CreateStandardInstance();
applySomeDiscountOrWhatever(broadband, phoneline, mobile);
}
private static void applySomeDiscountOrWhatever(Broadband bb, Phoneline pl, Mobile m) {
// some logic here
// maybe manange some variables and invoke some other methods/services/etc.
}
}
Hope this helps.
An alternative way to get only one character.
$str = 'abcdefghij';
echo $str{5};
I would particularly not use this, but for the purpose of education. We can use that to answer the question:
$newString = '';
for ($i = 0; $i < 5; $i++) {
$newString .= $str{$i};
}
echo $newString;
For anyone using that. Bear in mind curly brace syntax for accessing array elements and string offsets is deprecated from PHP 7.4
More information: https://wiki.php.net/rfc/deprecate_curly_braces_array_access
You can use this plugin timer_builder
timer_builder widget that rebuilds itself on scheduled, periodic, or dynamically generated time events.
Examples
Periodic rebuild
import 'package:timer_builder/timer_builder.dart';
class ClockWidget extends StatelessWidget {
@override
Widget build(BuildContext context) {
return TimerBuilder.periodic(Duration(seconds: 1),
builder: (context) {
return Text("${DateTime.now()}");
}
);
}
}
Rebuild on a schedule
import 'package:timer_builder/timer_builder.dart';
class StatusIndicator extends StatelessWidget {
final DateTime startTime;
final DateTime endTime;
StatusIndicator(this.startTime, this.endTime);
@override
Widget build(BuildContext context) {
return TimerBuilder.scheduled([startTime, endTime],
builder: (context) {
final now = DateTime.now();
final started = now.compareTo(startTime) >= 0;
final ended = now.compareTo(endTime) >= 0;
return Text(started ? ended ? "Ended": "Started": "Not Started");
}
);
}
}
SELECT DISTINCT groups.id,
(SELECT COUNT(*) FROM group_members
WHERE member_id = groups.id) AS memberCount
FROM groups
Try this,
<iframe id="testframe" src="about:blank" onload="if (testframe.location.href != 'about:blank') testframe_loaded()"></iframe>
All you need to do then is create the JavaScript function testframe_loaded().
To use the hex
encoding in Python 3, use
>>> import codecs
>>> codecs.encode(b"c", "hex")
b'63'
In legacy Python, there are several other ways of doing this:
>>> hex(ord("c"))
'0x63'
>>> format(ord("c"), "x")
'63'
>>> "c".encode("hex")
'63'
When it is on server side, use web services - maybe RESTful with JSON.
When Java code is in applet you can use JavaScript bridge. The bridge between the Java and JavaScript programming languages, known informally as LiveConnect, is implemented in Java plugin. Formerly Mozilla-specific LiveConnect functionality, such as the ability to call static Java methods, instantiate new Java objects and reference third-party packages from JavaScript, is now available in all browsers.
Below is example from documentation. Look at methodReturningString
.
Java code:
public class MethodInvocation extends Applet {
public void noArgMethod() { ... }
public void someMethod(String arg) { ... }
public void someMethod(int arg) { ... }
public int methodReturningInt() { return 5; }
public String methodReturningString() { return "Hello"; }
public OtherClass methodReturningObject() { return new OtherClass(); }
}
public class OtherClass {
public void anotherMethod();
}
Web page and JavaScript code:
<applet id="app"
archive="examples.jar"
code="MethodInvocation" ...>
</applet>
<script language="javascript">
app.noArgMethod();
app.someMethod("Hello");
app.someMethod(5);
var five = app.methodReturningInt();
var hello = app.methodReturningString();
app.methodReturningObject().anotherMethod();
</script>
Many browsers have changed their security policies to no longer allow reading data directly from file shares or even local resources. You need to either place the files somewhere that your tomcat instance can serve them up and put a "regular" http url in the html you generate. This can be accomplished by either providing a servlet which reads and provides the file putting the file into a directory where tomcat will serve it up as "static" content.
<%= link_to "http://www.facebook.com/sharer.php?u=" + article_url(article, :text => article.title), :class => "btn btn-primary" do %> <i class="fa fa-facebook"> Facebook Share </i> <%end%>
I am assuming that current_article_url
is http://0.0.0.0:4567/link_to_title
Use an image editor to cut out a portion of the background, then apply CSS's background-repeat property to make the small image fill the area where it is used.
In some cases, background-repeat creates seams where the image repeats. A solution is to use an image editor as follows: starting with the background image, copy the image, flip (mirror, not rotate) the copy left-to-right, and paste it to the right edge of the original, overlapping 1 pixel. Crop to remove 1 pixel from the right edge of the combined image. Now repeat for the vertical: copy the combined image, flip the copy top-to-bottom, paste it to the bottom of the combined, overlapping one pixel. Crop to remove 1 pixel from the bottom. The resulting image should be seam-free.
If you want all of the values, use this:
dict_name_goes_here.values()
A very simple way to read an external script into an sqlite database in python is using executescript()
:
import sqlite3
conn = sqlite3.connect('csc455_HW3.db')
with open('ZooDatabase.sql', 'r') as sql_file:
conn.executescript(sql_file.read())
conn.close()
func post() {
NotificationCenter.default.post(name: Notification.Name("SomeNotificationName"),
object: nil,
userInfo:["key0": "value", "key1": 1234])
}
func addObservers() {
NotificationCenter.default.addObserver(self,
selector: #selector(someMethod),
name: Notification.Name("SomeNotificationName"),
object: nil)
}
@objc func someMethod(_ notification: Notification) {
let info0 = notification.userInfo?["key0"]
let info1 = notification.userInfo?["key1"]
}
Replace Notification.Name("SomeNotificationName")
with .someNotificationName
:
extension Notification.Name {
static let someNotificationName = Notification.Name("SomeNotificationName")
}
Replace "key0"
and "key1"
with Notification.Key.key0
and Notification.Key.key1
:
extension Notification {
enum Key: String {
case key0
case key1
}
}
Why should I definitely do this ? To avoid costly typo errors, enjoy renaming, enjoy find usage etc...
If you are on SQL Server 2008 you can also use
CRYPT_GEN_RANDOM(2) % 10000
Which seems somewhat simpler (it is also evaluated once per row as newid
is - shown below)
DECLARE @foo TABLE (col1 FLOAT)
INSERT INTO @foo SELECT 1 UNION SELECT 2
UPDATE @foo
SET col1 = CRYPT_GEN_RANDOM(2) % 10000
SELECT * FROM @foo
Returns (2 random probably different numbers)
col1
----------------------
9693
8573
Mulling the unexplained downvote the only legitimate reason I can think of is that because the random number generated is between 0-65535 which is not evenly divisible by 10,000 some numbers will be slightly over represented. A way around this would be to wrap it in a scalar UDF that throws away any number over 60,000 and calls itself recursively to get a replacement number.
CREATE FUNCTION dbo.RandomNumber()
RETURNS INT
AS
BEGIN
DECLARE @Result INT
SET @Result = CRYPT_GEN_RANDOM(2)
RETURN CASE
WHEN @Result < 60000
OR @@NESTLEVEL = 32 THEN @Result % 10000
ELSE dbo.RandomNumber()
END
END
I had the same problem, it was a missing manifest.json file, if not found the browser decide with orientation is best fit, if you don't specify the file or use a wrong path.
I fixed just calling the manifest.json correctly on html headers.
My html headers:
<meta name="application-name" content="App Name">
<meta name="mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
<link rel="manifest" href="manifest.json">
<meta name="msapplication-starturl" content="/">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<meta name="theme-color" content="#">
<meta name="msapplication-TileColor" content="#">
<meta name="msapplication-config" content="browserconfig.xml">
<link rel="icon" type="image/png" sizes="192x192" href="android-chrome-192x192.png">
<link rel="apple-touch-icon" sizes="180x180" href="apple-touch-icon.png">
<link rel="mask-icon" href="safari-pinned-tab.svg" color="#ffffff">
<link rel="shortcut icon" href="favicon.ico">
And the manifest.json file content:
{
"display": "standalone",
"orientation": "portrait",
"start_url": "/",
"theme_color": "#000000",
"background_color": "#ffffff",
"icons": [
{
"src": "android-chrome-192x192.png",
"sizes": "192x192",
"type": "image/png"
}
}
To generate your favicons and icons use this webtool: https://realfavicongenerator.net/
To generate your manifest file use: https://tomitm.github.io/appmanifest/
My PWA Works great, hope it helps!
I recommend you to generate an open format XML Excel file, is much more flexible than CSV.
Read Generating an Excel file in ASP.NET for more info
"MyTable".DefaultView.RowFilter = " LIKE '%" + textBox1.Text + "%'"; this.dataGridView1.DataSource = "MyTable".DefaultView;
How about the relation to the database connections and the Datatable? And how should i set the DefaultView correct?
I use this code to get the data out:
con = new System.Data.SqlServerCe.SqlCeConnection();
con.ConnectionString = "Data Source=C:\\Users\\mhadj\\Documents\\Visual Studio 2015\\Projects\\data_base_test_2\\Sample.sdf";
con.Open();
DataTable dt = new DataTable();
adapt = new System.Data.SqlServerCe.SqlCeDataAdapter("select * from tbl_Record", con);
adapt.Fill(dt);
dataGridView1.DataSource = dt;
con.Close();
Quick helper method that might address this situation:
<T> T onlyItem(Collection<T> items) {
if (items.size() != 1)
throw new IllegalArgumentException("Collection must have single item; instead it has " + items.size());
return items.iterator().next();
}
Easy peasy. Your data frame will look like this:
df <- data.frame(sex=c('M','F','M'),
occupation=c('Student','Analyst','Analyst'))
You can then do the equivalent of a COUNTIF
by first specifying the IF
part, like so:
df$sex == 'M'
This will give you a boolean vector, i.e. a vector of TRUE
and FALSE
. What you want is to count the observations for which the condition is TRUE
. Since in R TRUE
and FALSE
double as 1 and 0 you can simply sum()
over the boolean vector. The equivalent of COUNTIF(sex='M')
is therefore
sum(df$sex == 'M')
Should there be rows in which the sex
is not specified the above will give back NA
. In that case, if you just want to ignore the missing observations use
sum(df$sex == 'M', na.rm=TRUE)
There are some great answers above. Here is an all-in-one solution. Three overloads for different circumstances.
// Extension method, call for any object, eg "if (x.IsNumeric())..."
public static bool IsNumeric(this object x) { return (x==null ? false : IsNumeric(x.GetType())); }
// Method where you know the type of the object
public static bool IsNumeric(Type type) { return IsNumeric(type, Type.GetTypeCode(type)); }
// Method where you know the type and the type code of the object
public static bool IsNumeric(Type type, TypeCode typeCode) { return (typeCode == TypeCode.Decimal || (type.IsPrimitive && typeCode != TypeCode.Object && typeCode != TypeCode.Boolean && typeCode != TypeCode.Char)); }
Modern browsers have built-in javascript functions for Base64 encoding btoa() and decoding atob(). More info about support in older browser versions: https://caniuse.com/?search=atob
However, be aware that atob
and btoa
functions work only for ASCII charset.
If you need Base64 functions for UTF-8 charset, you can do it with:
function base64_encode(s) {
return btoa(unescape(encodeURIComponent(s)));
}
function base64_decode(s) {
return decodeURIComponent(escape(atob(s)));
}
Try this Javascript (jquery) code. Its an ajax request to an external URL. Use the callback function to fire any code:
<script type="text/javascript">
$(function() {
$('form').submit(function(){
$.post('http://example.com/upload', function() {
window.location = 'http://google.com';
});
return false;
});
});
</script>
One consideration is that FTP can use non-standard ports, which can make getting though firewalls difficult (especially if you're using SSL). HTTP is typically on a known port, so this is rarely a problem.
If you do decide to use FTP, make sure you read about Active and Passive FTP.
In terms of performance, at the end of the day they're both spewing files directly down TCP connections so should be about the same.
Programmatically, you could use:
textView.setTextAppearance(android.R.style.TextAppearance_Large);
There are two main ways to change the port in the Embedded Tomcat in a Spring Boot Application.
Modify application.properties
First you can try the application.properties file in the /resources folder:
server.port = 8090
Modify a VM option
The second way, if you want to avoid modifying any files and checking in something that you only need on your local, you can use a vm arg:
Go to Run -> Edit Configurations -> VM options
-Dserver.port=8090
Additionally, if you need more information you can view the following blog post here: Changing the port on a Spring Boot Application

Talvi's answer may still work, but that Youtube Javascript API has been marked as deprecated. You should now be using the newer Youtube IFrame API.
The documentation provides a few ways to accomplish video embedding, but for your goal, you'd include the following:
//load the IFrame Player API code asynchronously
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
//will be youtube player references once API is loaded
var players = [];
//gets called once the player API has loaded
function onYouTubeIframeAPIReady() {
$('.myiframeclass').each(function() {
var frame = $(this);
//create each instance using the individual iframe id
var player = new YT.Player(frame.attr('id'));
players.push(player);
});
}
//global stop button click handler
$('#mybutton').click(function(){
//loop through each Youtube player instance and call stopVideo()
for (var i in players) {
var player = players[i];
player.stopVideo();
}
});
This should be very simple if Google Calendar does not require the *.ics
-extension (which will require some URL rewriting in the server).
$ical = "BEGIN:VCALENDAR

END:VCALENDAR";
//set correct content-type-header
header('Content-type: text/calendar; charset=utf-8');
header('Content-Disposition: inline; filename=calendar.ics');
echo $ical;
exit;
That's essentially all you need to make a client think that you're serving a iCalendar file, even though there might be some issues regarding caching, text encoding and so on. But you can start experimenting with this simple code.
You bind in onResume
but unbind in onDestroy
. You should do the unbinding in onPause
instead, so that there are always matching pairs of bind/unbind calls. Your intermittent errors will be where your activity is paused but not destroyed, and then resumed again.
Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.
Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .
if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .
if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .
after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).
if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.
If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.
If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.
If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.
if you further face any difficulty then you need to provide more information about your web site and sql server .
This is extreme, but I built a dynamic, database-driven filter using a 2 column database table named FILE_TYPES, with field names EXTENSION and DOCTYPE:
---------------------------------
| EXTENSION | DOCTYPE |
---------------------------------
| .doc | Document |
| .docx | Document |
| .pdf | Document |
| ... | ... |
| .bmp | Image |
| .jpg | Image |
| ... | ... |
---------------------------------
Obviously I had many different types and extensions, but I'm simplifying it for this example. Here is my function:
private static string GetUploadFilter()
{
// Desired format:
// "Document files (*.doc, *.docx, *.pdf)|*.doc;*.docx;*.pdf|"
// "Image files (*.bmp, *.jpg)|*.bmp;*.jpg|"
string filter = String.Empty;
string nameFilter = String.Empty;
string extFilter = String.Empty;
// Used to get extensions
DataTable dt = new DataTable();
dt = DataLayer.Get_DataTable("SELECT * FROM FILE_TYPES ORDER BY EXTENSION");
// Used to cycle through doctype groupings ("Images", "Documents", etc.)
DataTable dtDocTypes = new DataTable();
dtDocTypes = DataLayer.Get_DataTable("SELECT DISTINCT DOCTYPE FROM FILE_TYPES ORDER BY DOCTYPE");
// For each doctype grouping...
foreach (DataRow drDocType in dtDocTypes.Rows)
{
nameFilter = drDocType["DOCTYPE"].ToString() + " files (";
// ... add its associated extensions
foreach (DataRow dr in dt.Rows)
{
if (dr["DOCTYPE"].ToString() == drDocType["DOCTYPE"].ToString())
{
nameFilter += "*" + dr["EXTENSION"].ToString() + ", ";
extFilter += "*" + dr["EXTENSION"].ToString() + ";";
}
}
// Remove endings put in place in case there was another to add, and end them with pipe characters:
nameFilter = nameFilter.TrimEnd(' ').TrimEnd(',');
nameFilter += ")|";
extFilter = extFilter.TrimEnd(';');
extFilter += "|";
// Add the name and its extensions to our main filter
filter += nameFilter + extFilter;
extFilter = ""; // clear it for next round; nameFilter will be reset to the next DOCTYPE on next pass
}
filter = filter.TrimEnd('|');
return filter;
}
private void UploadFile(string fileType, object sender)
{
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
string filter = GetUploadFilter();
dlg.Filter = filter;
if (dlg.ShowDialog().Value == true)
{
string fileName = dlg.FileName;
System.IO.FileStream fs = System.IO.File.OpenRead(fileName);
byte[] array = new byte[fs.Length];
// This will give you just the filename
fileName = fileName.Split('\\')[fileName.Split('\\').Length - 1];
...
Should yield a filter that looks like this:
NSIndexPath * index = [self.menuTableView indexPathForSelectedRow];
[self.menuTableView deselectRowAtIndexPath:index animated:NO];
place this code according to your code and you will get your cell deselected.
This message will appear if you are using a case-insensitive file system (e.g. on a Mac) and you're trying to capitalize the name (or another change of case). In which case you need to rename to a third, dummy, name:
svn mv file-name file-name_
svn mv file-name_ FILE_Name
svn commit
Simply copy paste the following code and it does the trick.
editMsg.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
final int DRAWABLE_LEFT = 0;
final int DRAWABLE_TOP = 1;
final int DRAWABLE_RIGHT = 2;
final int DRAWABLE_BOTTOM = 3;
if(event.getAction() == MotionEvent.ACTION_UP) {
if(event.getRawX() >= (editMsg.getRight() - editMsg.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
// your action here
Toast.makeText(ChatActivity.this, "Message Sent", Toast.LENGTH_SHORT).show();
return true;
}
}
return false;
}
});
We added JUnit integration to our Java to Javascript code generator ST-JS (http://st-js.org). The framework generates to corresponding Javascript for both the tested code and the unit tests and sends the code to different browsers.
There is no need for a separate server as the unit test runner opens the needed http port (and closes it once the tests finished). The framework manipulates the Java stacktrace so that the failed asserts are correctly displayed by the JUnit Eclipse plugin. Here is a simple example with jQuery and Mockjax:
@RunWith(STJSTestDriverRunner.class)
@HTMLFixture("<div id='fortune'></div>")
@Scripts({ "classpath://jquery.js",
"classpath://jquery.mockjax.js", "classpath://json2.js" })
public class MockjaxExampleTest {
@Test
public void myTest() {
$.ajaxSetup($map("async", false));
$.mockjax(new MockjaxOptions() {
{
url = "/restful/fortune";
responseText = new Fortune() {
{
status = "success";
fortune = "Are you a turtle?";
}
};
}
});
$.getJSON("/restful/fortune", null, new Callback3<Fortune, String, JQueryXHR>() {
@Override
public void $invoke(Fortune response, String p2, JQueryXHR p3) {
if (response.status.equals("success")) {
$("#fortune").html("Your fortune is: " + response.fortune);
} else {
$("#fortune").html("Things do not look good, no fortune was told");
}
}
});
assertEquals("Your fortune is: Are you a turtle?", $("#fortune").html());
}
private static class Fortune {
public String status;
public String fortune;
}
}
Also, I had this issue using Laravel, but fixed by changing my database schema to allow "null" inputs on a table where I plan to collect the information from separate forms:
public function up()
{
Schema::create('trip_table', function (Blueprint $table) {
$table->increments('trip_id')->unsigned();
$table->time('est_start');
$table->time('est_end');
$table->time('act_start')->nullable();
$table->time('act_end')->nullable();
$table->date('Trip_Date');
$table->integer('Starting_Miles')->nullable();
$table->integer('Ending_Miles')->nullable();
$table->string('Bus_id')->nullable();
$table->string('Event');
$table->string('Desc')->nullable();
$table->string('Destination');
$table->string('Departure_location');
$table->text('Drivers_Comment')->nullable();

Expressions only contain identifiers, literals and operators, where operators include arithmetic and boolean operators, the function call operator ()
the subscription operator []
and similar, and can be reduced to some kind of "value", which can be any Python object. Examples:
3 + 5
map(lambda x: x*x, range(10))
[a.x for a in some_iterable]
yield 7
Statements (see 1, 2), on the other hand, are everything that can make up a line (or several lines) of Python code. Note that expressions are statements as well. Examples:
# all the above expressions
print 42
if x: do_y()
return
a = 7
do you use Bash? Go to the file .bashrc in your home directory and set the variable, then export it.
DISPLAY=localhost:0.0 ; export DISPLAY
you can use /etc/bashrc if you want to do it for all the users.
You may also want to look in ~/.bash_profile and /etc/profile

How do we do for CI CD
try out with this fastest JSON framework JSONKit. it's faster than normal JSON framework.
Session storage cannot support an arbitrary object because it may contain function literals (read closures) which cannot be reconstructed after a page reload.
Here is a slightly improved version of sonjz's answer,it adds an overwrite option.
function Zip-Files(
[Parameter(Position=0, Mandatory=$true, ValueFromPipeline=$false)]
[string] $zipfilename,
[Parameter(Position=1, Mandatory=$true, ValueFromPipeline=$false)]
[string] $sourcedir,
[Parameter(Position=2, Mandatory=$false, ValueFromPipeline=$false)]
[bool] $overwrite)
{
Add-Type -Assembly System.IO.Compression.FileSystem
$compressionLevel = [System.IO.Compression.CompressionLevel]::Optimal
if ($overwrite -eq $true )
{
if (Test-Path $zipfilename)
{
Remove-Item $zipfilename

I authored a plugin to address this scenario. I was unhappy with the plugins out there, and set out to make something more extensive/configurable.
Paste my contains
example here:
//table[contains(@class, "EC_result")]/tbody
you can use fileinput to do in place editing
import fileinput
for line in fileinput.FileInput("myfile", inplace=1):
if line .....:
print line
A well explained by flatline. I just want to add a simple example. which makes it easy to understand for beginners.
func.call(context, args1 , args2 ); // pass arguments as "," saprated value
func.apply(context, [args1 , args2 ]); // pass arguments as "Array"
we also use "Call" and "Apply" method for changing reference as defined in code below
let Emp1 = {_x000D_
name: 'X',_x000D_
getEmpDetail: function (age, department) {_x000D_
console.log('Name :', this.name, ' Age :', age, ' Department :', department)_x000D_
}_x000D_
}_x000D_
Emp1.getEmpDetail(23, 'Delivery')_x000D_
_x000D_
// 1st approch of chenging "this"_x000D_
let Emp2 = {_x000D_
name: 'Y',_x000D_
getEmpDetail: Emp1.getEmpDetail_x000D_
}_x000D_
Emp2.getEmpDetail(55, 'Finance')_x000D_
_x000D_
// 2nd approch of changing "this" using "Call" and "Apply"_x000D_
let Emp3 = {_x000D_
name: 'Z',_x000D_
}_x000D_
_x000D_
Emp1.getEmpDetail.call(Emp3, 30, 'Admin') _x000D_
// here we have change the ref from **Emp1 to Emp3** object_x000D_
// now this will print "Name = X" because it is pointing to Emp3 object_x000D_
Emp1.getEmpDetail.apply(Emp3, [30, 'Admin']) //
_x000D_
You can use deletgate
with scp
too:
- name: Copy file to another server
become: true
shell: "scp -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null admin@{{ inventory_hostname }}:/tmp/file.yml /tmp/file.yml"
delegate_to: other.example.com
Because of delegate
the command is run on the other server and it scp
's the file to itself.
This answer is for docker-compose version 2 and it also works on version 3
You can still access the data when you use depends_on.
If you look at docker docs Docker Compose and Django, you still can access the database like this:
version: '2'
services:
db:
image: postgres
web:
build: .
command: python manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
ports:
- "8000:8000"
depends_on:
- db
What is the difference between links and depends_on?
links:
When you create a container for a database, for example:
docker run -d --name=test-mysql --env="MYSQL_ROOT_PASSWORD=mypassword" -P mysql
docker inspect d54cf8a0fb98 |grep HostPort
And you may find
"HostPort": "32777"
This means you can connect the database from your localhost port 32777 (3306 in container) but this port will change every time you restart or remove the container. So you can use links to make sure you will always connect to the database and don't have to know which port it is.
web:
links:
- db
depends_on:
I found a nice blog from Giorgio Ferraris Docker-compose.yml: from V1 to V2
When docker-compose executes V2 files, it will automatically build a network between all of the containers defined in the file, and every container will be immediately able to refer to the others just using the names defined in the docker-compose.yml file.
And
So we don’t need links anymore; links were used to start a network communication between our db container and our web-server container, but this is already done by docker-compose
Express dependency between services, which has two effects:
docker-compose up
will start services in dependency order. In the following example, db and redis will be started before web.docker-compose up SERVICE
will automatically include SERVICE’s dependencies. In the following example, docker-compose up web will also create and start db and redis.Simple example:
version: '2'
services:
web:
build: .
depends_on:
- db
- redis
redis:
image: redis
db:
image: postgres
Note: depends_on will not wait for db and redis to be “ready” before starting web - only until they have been started. If you need to wait for a service to be ready, see Controlling startup order for more on this problem and strategies for solving it.
The selected answer posted here solved one problem, but another is that you'll have to change the app pool to use .Net 2.0.
"SharePoint 2010 uses .NET Framework 3.5, not 4.0. The SharePoint 2010 app pools should be configured as .NET Framework 2.0 using the Integrated Pipeline Mode."
On Google'e Gson library, for having a JsonObject
, or more abstract a JsonElement
:
import com.google.gson.JsonElement;
import com.google.gson.JsonParser;
JsonElement json = JsonParser.parseReader( new InputStreamReader(new FileInputStream("/someDir/someFile.json"), "UTF-8") );
This is not demanding a given Object structure for receiving/reading the json string.
You can use hr (horizontal line) tag and than rotate it 90 degree with css below
hr {
transform:rotate(90deg);
-o-transform:rotate(90deg);
-moz-transform:rotate(90deg);
-webkit-transform:rotate(90deg);
}
What about using idate()? idate()
$integer = idate('w', $timestamp);
Had same problem with some non-licensed cables. Works fine with Apple's & Belkin's USB cables.
Parameters in the URL are GET parameters, a request body, if present, is POST data. So your basic premise is by definition not achievable.
You should choose whether to use POST or GET based on the action. Any destructive action, i.e. something that permanently changes the state of the server (deleting, adding, editing) should always be invoked by POST requests. Any pure "information retrieval" should be accessible via an unchanging URL (i.e. GET requests).
To make a POST request, you need to create a <form>
. You could use Javascript to create a POST request instead, but I wouldn't recommend using Javascript for something so basic. If you want your submit button to look like a link, I'd suggest you create a normal form with a normal submit button, then use CSS to restyle the button and/or use Javascript to replace the button with a link that submits the form using Javascript (depending on what reproduces the desired behavior better). That'd be a good example of progressive enhancement.
You need both a value and a field to assign it to. The value is TableField + 1
, so the assignment is:
SET TableField = TableField + 1
The oracle tag was not on the question when this answer was offered, and apparently it doesn't work with oracle, but it does work with at least postgres and mysql
No, just use the value directly:
begin
if (select count(*) from table) > 0 then
update table
end if;
end;
Note there is no need for an "else".
You can simply do it all within the update statement (ie no if
construct):
update table
set ...
where ...
and exists (select 'x' from table where ...)
Just to complete the answer (using the KeyEvent is the way to go) but up arrow is 38 and down arrow is 40 so:
else if (e.getKeyCode()==38)
{
//Up arrow key code
}
else if (e.getKeyCode()==40)
{
//down arrow key code
}
Let me add this one, because sometimes you just want the single digit representation
( x
can be lower, 'x', or uppercase, 'X', the choice determines if the output letters are upper or lower.):
'{:x}'.format(15)
> f
And now with the new f''
format strings you can do:
f'{15:x}'
> f
To add 0 padding you can use 0>n
:
f'{2034:0>4X}'
> 07F2
NOTE: the initial 'f' in
f'{15:x}'
is to signify a format string
Nope. Once the event has been canceled, it is canceled.
You can re-fire the event later on though, using a flag to determine whether your custom code has already run or not - such as this (please ignore the blatant namespace pollution):
var lots_of_stuff_already_done = false;
$('.button').on('click', function(e) {
if (lots_of_stuff_already_done) {
lots_of_stuff_already_done = false; // reset flag
return; // let the event bubble away
}
e.preventDefault();
// do lots of stuff
lots_of_stuff_already_done = true; // set flag
$(this).trigger('click');
});
A more generalized variant (with the added benefit of avoiding the global namespace pollution) could be:
function onWithPrecondition(callback) {
var isDone = false;
return function(e) {
if (isDone === true)
{
isDone = false;
return;
}
e.preventDefault();
callback.apply(this, arguments);
isDone = true;
$(this).trigger(e.type);
}
}
Usage:
var someThingsThatNeedToBeDoneFirst = function() { /* ... */ } // do whatever you need
$('.button').on('click', onWithPrecondition(someThingsThatNeedToBeDoneFirst));
Bonus super-minimalistic jQuery plugin with Promise
support:
(function( $ ) {
$.fn.onButFirst = function(eventName, /* the name of the event to bind to, e.g. 'click' */
workToBeDoneFirst, /* callback that must complete before the event is re-fired */
workDoneCallback /* optional callback to execute before the event is left to bubble away */) {
var isDone = false;
this.on(eventName, function(e) {
if (isDone === true) {
isDone = false;
workDoneCallback && workDoneCallback.apply(this, arguments);
return;
}
e.preventDefault();
// capture target to re-fire event at
var $target = $(this);
// set up callback for when workToBeDoneFirst has completed
var successfullyCompleted = function() {
isDone = true;
$target.trigger(e.type);
};
// execute workToBeDoneFirst callback
var workResult = workToBeDoneFirst.apply(this, arguments);
// check if workToBeDoneFirst returned a promise
if (workResult && $.isFunction(workResult.then))
{
workResult.then(successfullyCompleted);
}
else
{
successfullyCompleted();
}
});
return this;
};
}(jQuery));
Usage:
$('.button').onButFirst('click',
function(){
console.log('doing lots of work!');
},
function(){
console.log('done lots of work!');
});
Add this in your .htaccess file:

It seems like one 'answer' to this is to implement an SMPT client. See email.js for a JavaScript library with an SMTP client.
Here's the GitHub repo for the SMTP client. Based on the repo's README, it appears that various shims or polyfills may be required depending on the client browser, but overall it does certainly seem feasible (if not actually significantly accomplished), tho not in a way that's easily describable by even a reasonably-long answer here.
Pattern rules let you compile multiple c files which require the same compilation commands using make
as follows:
objects = program1 program2
all: $(objects)
$(objects): %: %.c
$(CC) $(CFLAGS) -o $@ $<
dynamic_cast should be what you are looking for.
EDIT:
DerivedType m_derivedType = m_baseType; // gives same error
The above appears to be trying to invoke the assignment operator, which is probably not defined on type DerivedType and accepting a type of BaseType.
DerivedType * m_derivedType = (DerivedType*) & m_baseType; // gives same error
You are on the right path here but the usage of the dynamic_cast will attempt to safely cast to the supplied type and if it fails, a NULL will be returned.
Going on memory here, try this (but note the cast will return NULL as you are casting from a base type to a derived type):
DerivedType * m_derivedType = dynamic_cast<DerivedType*>(&m_baseType);
If m_baseType was a pointer and actually pointed to a type of DerivedType, then the dynamic_cast should work.
Hope this helps!

try the below one. it will give ur expected output
select c.name as Fields from
tempdb.sys.columns c
inner join tempdb.sys.tables t
ON c.object_id = t.object_id
where t.name like '#MyTempTable%'
The easiest way to get a new list would be:
List<long> unique = longs.Distinct().ToList();
Is that good enough for you, or do you need to mutate the existing list? The latter is significantly more long-winded.
Note that Distinct()
isn't guaranteed to preserve the original order, but in the current implementation it will - and that's the most natural implementation. See my Edulinq blog post about Distinct()
for more information.
If you don't need it to be a List<long>
, you could just keep it as:
IEnumerable<long> unique = longs.Distinct();
At this point it will go through the de-duping each time you iterate over unique
though. Whether that's good or not will depend on your requirements.
It looks like you have accidentally declared DataType
as an array rather than as a string.
Change line 3 to:
Dim DataType As String = myTableData.Rows(i).Item(1)
That should work.
A Java String is internally always encoded in UTF-16 - but you really should think about it like this: an encoding is a way to translate between Strings and bytes.
So if you have an encoding problem, by the time you have String, it's too late to fix. You need to fix the place where you create that String from a file, DB or network connection.

All you have to do is assign this property:
img {
display: block;
}
The images by default have this property:
img {
display: inline;
}
there is HeaderText property in Column object, you can find the column and set its HeaderText after initializing grid or do it in windows form designer via designer for DataGrid.
public Form1()
{
InitializeComponent();
grid.Columns[0].HeaderText = "First Column";
//..............
}
More details are here at MSDN. More details about DataGrid are here.
as your service is already setup, simply add a broadcast receiver in your service:
private final BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(action.equals("android.provider.Telephony.SMS_RECEIVED")){
//action for sms received
}
else if(action.equals(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED)){
//action for phone state changed
}
}
};
in your service's onCreate
do this:
IntentFilter filter = new IntentFilter();
filter.addAction("android.provider.Telephony.SMS_RECEIVED");
filter.addAction(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED);
filter.addAction("your_action_strings"); //further more
filter.addAction("your_action_strings"); //further more
registerReceiver(receiver, filter);
and in your service's onDestroy
:
unregisterReceiver(receiver);
and you are good to go to receive broadcast for what ever filters you mention in onCreate
. Make sure to add any permission if required. for e.g.
<uses-permission android:name="android.permission.RECEIVE_SMS" />
I have found this link
I have no idea why this works but I tried many work arounds and this is the only one that worked for me. In short, run the three commands below:
git fsck --full
git reflog expire --expire=now --all
git gc --prune=now
\t
is a tab character. Use a raw string instead:
test_file=open(r'c:\Python27\test.txt','r')
or double the slashes:
test_file=open('c:\\Python27\\test.txt','r')
or use forward slashes instead:
test_file=open('c:/Python27/test.txt','r')
Remove your "each" and just use:
$('input[name=ticketID]').attr("disabled",true);
That simple. It works
You should use
document.documentElement.clientWidth
It is regarded as cross-browser compability, and is the same method that jQuery(window).width(); uses.
For detailed information have a look at: https://ryanve.com/lab/dimensions/
Because string
is defined in the namespace std
. Replace string
with std::string
, or add
using std::string;
below your include
lines.
It probably works in main.cpp
because some other header has this using
line in it (or something similar).
If you want to recursively convert the entire array into an Object type (stdClass) then , below is the best method and it's not time-consuming or memory deficient especially when you want to do a recursive (multi-level) conversion compared to writing your own function.
$array_object = json_decode(json_encode($array));
NOTICE: This is never a recommended use of git. This will overwrite changes on the remote. Only do this if you know 100% that your local changes should be pushed to the remote master.

Since C++17 the inline specifier also applies to variables. You can now define static member variables in the class definition:
#include <string>
class foo {
public:
foo();
foo( int );
private:
inline static const std::string s { "foo" };
};
From wikipedia:
In computer science, an array data structure or simply array is a data structure consisting of a collection of elements (values or variables), each identified by one or more integer indices, stored so that the address of each element can be computed from its index tuple by a simple mathematical formula.
So when you say byte array, you're referring to an array of some defined length (e.g. number of elements) that contains a collection of byte (8 bits) sized elements.
In C# a byte array could look like:
byte[] bytes = { 3, 10, 8, 25 };
The sample above defines an array of 4 elements, where each element can be up to a Byte in length.
There is a crop()
method:
w, h = yourImage.size
yourImage.crop((0, 30, w, h-30)).save(...)
Eventually a native :terminal
command was added to vim in 2017.
Here is an excerpt from the :terminal readme:
This feature is for running a terminal emulator in a Vim window. A job can be started connected to the terminal emulator. For example, to run a shell:
:term bash
Or to run build command:
:term make myprogram
The job runs asynchronously from Vim, the window will be updated to show output from the job, also while editing in another window.
There's more to it than this, but you're probably looking for this list:

C custom business day frequency (experimental)
D calendar day frequency
W weekly frequency
M month end frequency
BM business month end frequency
MS month start frequency
BMS business month start frequency
Q quarter end frequency
BQ business quarter endfrequency
QS quarter start frequency
BQS business quarter start frequency
A year end frequency
BA business year end frequency
AS year start frequency
BAS business year start frequency
H hourly frequency
T minutely frequency
S secondly frequency
L milliseconds
U microseconds

The only way to have multiple, separately accessible functions in a single file is to define STATIC METHODS using object-oriented programming. You'd access the function as myClass.static1()
, myClass.static2()
etc.
OOP functionality is only officially supported since R2008a, so unless you want to use the old, undocumented OOP syntax, the answer for you is no, as explained by @gnovice.
EDIT
One more way to define multiple functions inside a file that are accessible from the outside is to create a function that returns multiple function handles. In other words, you'd call your defining function as [fun1,fun2,fun3]=defineMyFunctions
, after which you could use out1=fun1(inputs)
etc.

a) Tokens are symbolic names for the entities that make up the text of the program; e.g. if for the keyword if, and id for any identifier. These make up the output of the lexical analyser. 5
(b) A pattern is a rule that specifies when a sequence of characters from the input constitutes a token; e.g the sequence i, f for the token if , and any sequence of alphanumerics starting with a letter for the token id.
(c) A lexeme is a sequence of characters from the input that match a pattern (and hence constitute an instance of a token); for example if matches the pattern for if , and foo123bar matches the pattern for id.
If your purpose is the isolation, I think Docker is what you want.
Vagrant is a virtual machine manager. It allows you to script the virtual machine configuration as well as the provisioning. However, it is still a virtual machine depending on VirtualBox (or others) with a huge overhead. It requires you to have a hard drive file that can be huge, it takes a lot of ram, and performance may be not very good.
Docker on the other hand uses kernel cgroup and namespacing via LXC. It means that you are using the same kernel as the host and the same file system.
You can use Dockerfile with the docker build
command in order to handle the provisioning and configuration of your container. You have an example at docs.docker.com on how to make your Dockerfile; it is very intuitive.
The only reason you could want to use Vagrant is if you need to do BSD, Windows or other non-Linux development on your Ubuntu box. Otherwise, go for Docker.
For me, to make it work I need to encode hex value of space within CDATA xml element, so that post parsing it adds up just as in the htm webgae & when viewed in browser just displays a space!. ( all above ideas & answers are useful )
<my-xml-element><![CDATA[ ]]></my-xml-element>
You need to enable the option
Project Properties -> Build -> Packaging -> Build JAR after compiling
(but this is enabled by default)
Try this:
CREATE PROCEDURE MyProc @excludedlist integer_list_tbltype READONLY AS
SELECT * FROM A WHERE ID NOT IN (@excludedlist)
And then call it like this:
DECLARE @ExcludedList integer_list_tbltype
INSERT @ExcludedList(n) VALUES(3, 4, 22)
exec MyProc @ExcludedList
There is no single magic function to force a frame to a minimum or fixed size. However, you can certainly force the size of a frame by giving the frame a width and height. You then have to do potentially two more things: when you put this window in a container you need to make sure the geometry manager doesn't shrink or expand the window. Two, if the frame is a container for other widget, turn grid or pack propagation off so that the frame doesn't shrink or expand to fit its own contents.
Note, however, that this won't prevent you from resizing a window to be smaller than an internal frame. In that case the frame will just be clipped.
import Tkinter as tk
root = tk.Tk()
frame1 = tk.Frame(root, width=100, height=100, background="bisque")
frame2 = tk.Frame(root, width=50, height = 50, background="#b22222")
frame1.pack(fill=None, expand=False)
frame2.place(relx=.5, rely=.5, anchor="c")
root.mainloop()
Python is strongly, dynamically typed.
As for your example
bob = 1
bob = "bob"
This works because the variable does not have a type; it can name any object. After bob=1
, you'll find that type(bob)
returns int
, but after bob="bob"
, it returns str
. (Note that type
is a regular function, so it evaluates its argument, then returns the type of the value.)
Contrast this with older dialects of C, which were weakly, statically typed, so that pointers and integers were pretty much interchangeable. (Modern ISO C requires conversions in many cases, but my compiler is still lenient about this by default.)
I must add that the strong vs. weak typing is more of a continuum than a boolean choice. C++ has stronger typing than C (more conversions required), but the type system can be subverted by using pointer casts.
The strength of the type system in a dynamic language such as Python is really determined by how its primitives and library functions respond to different types. E.g., +
is overloaded so that it works on two numbers or two strings, but not a string and an number. This is a design choice made when +
was implemented, but not really a necessity following from the language's semantics. In fact, when you overload +
on a custom type, you can make it implicitly convert anything to a number:
def to_number(x):
"""Try to convert function argument to float-type object."""
try:
return float(x)
except (TypeError, ValueError):
return 0
class Foo:
def __init__(self, number):
self.number = number
def __add__(self, other):
return self.number + to_number(other)
Instance of class Foo
can be added to other objects:
>>> a = Foo(42)
>>> a + "1"
43.0
>>> a + Foo
42
>>> a + 1
43.0
>>> a + None
42
Observe that even though strongly typed Python is completely fine with adding objects of type int
and float
and returns an object of type float
(e.g., int(42) + float(1)
returns 43.0
). On the other hand, due to the mismatch between types Haskell would complain if one tries the following (42 :: Integer) + (1 :: Float)
. This makes Haskell a strictly typed language, where types are entirely disjoint and only a controlled form of overloading is possible via type classes.

I know this is an old question. In my case I use Reportlab.
Sheet dimensions are expressed in points, not pixels, with a point equal to 1/72 inch. An A4 sheet is made up of 595.2 points width and 841.8 points height. The origin of the position coordinates (0, 0) is in the lower left corner. When creating an instance of canvas.Canvas, you can specify the size of the sheets using the pagesize parameter, passing a tuple whose first element represents the width in points and the second, the height. The c.showPage () method tells ReportLab that it has already finished working on the current sheet and moves on to the next one. Although a second sheet has not yet been worked on (and will not appear in the document as long as nothing has been drawn) it is good practice to remember to do so before invoking c.save (). To insert images into a PDF document, ReportLab uses the Pillow library. The drawImage () method takes as its argument the path of an image (supports multiple formats such as PNG, JPEG and GIF) and the position (x, y) in the that you want to insert. The image can be reduced or enlarged indicating its dimensions via the width and height arguments.
The following code provides pdf file name, list with png files, coordinates to insert images as well as size to fit in portrait letter pages.
def pntopd(file, figs, x, y, wi, he):
from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import A4, letter, landscape, portrait
w, h = letter
c = canvas.Canvas(str(file), pagesize=portrait(letter))
for png in figs:
c.drawImage(png, x, h - y, width=wi, height=he)
c.showPage()
c.save()
from datetime import date
from pathlib import Path
ruta = "C:/SQLite"
today = date.today()
dat_dir = Path(ruta)
tit = today.strftime("%y%m%d") + '_ParameterAudit'
pdf_file = tit + ".pdf"
pdf_path = dat_dir / pdf_file
pnglist = ['C0.png', 'C4387.png', 'C9712.png', 'C9685.png', 'C4364.png']
pntopd(pdf_path, pnglist, 50, 550, 500, 500)
I am assuming (please correct me if I am wrong) that you want to re-display the edit page if the edit fails and to do this you are using a redirect.
You may have more luck by just returning the view again rather than trying to redirect the user, this way you will be able to use the ModelState to output any errors too.
Edit:
Updated based on feedback. You can place the previous URL in the viewModel, add it to a hidden field then use it again in the action that saves the edits.
For instance:
public ActionResult Index()
{
return View();
}
[HttpGet] // This isn't required
public ActionResult Edit(int id)
{
// load object and return in view
ViewModel viewModel = Load(id);
// get the previous url and store it with view model
viewModel.PreviousUrl = System.Web.HttpContext.Current.Request.UrlReferrer;
return View(viewModel);
}
[HttpPost]
public ActionResult Edit(ViewModel viewModel)
{
// Attempt to save the posted object if it works, return index if not return the Edit view again
bool success = Save(viewModel);
if (success)
{
return Redirect(viewModel.PreviousUrl);
}
else
{
ModelState.AddModelError("There was an error");
return View(viewModel);
}
}
The BeginForm method for your view doesn't need to use this return URL either, you should be able to get away with:
@model ViewModel
@using (Html.BeginForm())
{
...
<input type="hidden" name="PreviousUrl" value="@Model.PreviousUrl" />
}
Going back to your form action posting to an incorrect URL, this is because you are passing a URL as the 'id' parameter, so the routing automatically formats your URL with the return path.
This won't work because your form will be posting to an controller action that won't know how to save the edits. You need to post to your save action first, then handle the redirect within it.
In C# this is how to get the resolution Screen:
button click or form load:
string screenWidth = Screen.PrimaryScreen.Bounds.Width.ToString();
string screenHeight = Screen.PrimaryScreen.Bounds.Height.ToString();
Label1.Text = ("Resolution: " + screenWidth + "x" + screenHeight);
The new filtering feature in Servlet 2.4 basically alleviates the restriction that filters can only operate in the request flow before and after the actual request processing by the application server. Instead, Servlet 2.4 filters can now interact with the request dispatcher at every dispatch point. This means that when a Web resource forwards a request to another resource (for instance, a servlet forwarding the request to a JSP page in the same application), a filter can be operating before the request is handled by the targeted resource. It also means that should a Web resource include the output or function from other Web resources (for instance, a JSP page including the output from multiple other JSP pages), Servlet 2.4 filters can work before and after each of the included resources. .
To turn on that feature you need:
web.xml
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/<strike>*</strike></url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
RegistrationController
return "forward:/login?j_username=" + registrationModel.getUserEmail()
+ "&j_password=" + registrationModel.getPassword();
You can also get microsecond precision from the time
module using its time()
function.
(time.time()
returns the time in seconds since epoch. Its fractional part is the time in microseconds, which is what you want.)
>>> from time import time
>>> time()
... 1310554308.287459 # the fractional part is what you want.
# comparision with strftime -
>>> from datetime import datetime
>>> from time import time
>>> datetime.now().strftime("%f"), time()
... ('287389', 1310554310.287459)
I had the same problem, and it turned out I hadn't installed the library.
this link was super usefull.
Note that namespaces that are in the format of a valid Web URL don't necessarily need to be dereferenced i.e. you don't need to serve actual content at that URL. All that matters is that the namespace is globally unique.
It's best if you judge on your own,
1) Sublime works on Mac & Linux that may be its plus point, with VI mode that makes things easily searchable for the VI lover(UNIX & Linux).

Initial observation revealed that everything else should work fine and almost similar;(with help of available plugins in notepad++)
Some Variation: Some user find plugins useful for PHP coders on that
http://codelikeapoem.com/2013/01/goodbye-notepad-hellooooo-sublime-text.html
although, there are many plugins for Notepad Plus Plus ..
I am not sure of your requirements, nor I am promoter of either of these editors :)
So, judge on basis of your requirements, this should satisfy you query...
Yes we can add that both are evolving and changing fast..
onConfigurationChanged is called when the screen rotates. (onCreate is no longer called when screen rotates due to manifest, see: android:configChanges)
What part of the manifest tells it "don't call onCreate()
"?
Also,
Google's docs say to avoid using android:configChanges
(except as a last resort).... But then the alternate methods they suggest all DO use android:configChanges
.
It has been my experience that the emulator ALWAYS calls onCreate()
upon rotation.
But the 1-2 devices that I run the same code on... do not.
(Not sure why there would be any difference.)
this prototype:
int execlp(const char *file, const char *arg, ...);
Says that execlp ìs a variable argument function. It takes 2 const char *
. The rest of the arguments, if any, are the additional arguments to hand over to program we want to run - also char *
- all these are C strings (and the last argument must be a NULL pointer)
So, the file
argument is the path name of an executable file to be executed. arg
is the string we want to appear as argv[0]
in the executable. By convention, argv[0]
is just the file name of the executable, normally it's set to the same as file
.
The ...
are now the additional arguments to give to the executable.
Say you run this from a commandline/shell:
$ ls
That'd be execlp("ls", "ls", (char *)NULL);
Or if you run
$ ls -l /
That'd be execlp("ls", "ls", "-l", "/", (char *)NULL);
So on to execlp("/bin/sh", ..., "ls -l /bin/??", ...);
Here you are going to the shell, /bin/sh , and you're giving the shell a command to execute. That command is "ls -l /bin/??". You can run that manually from a commandline/shell:
$ ls -l /bin/??
Now, how do you run a shell and tell it to execute a command ? You open up the documentation/man page for your shell and read it.
What you want to run is:
$ /bin/sh -c "ls -l /bin/??"
This becomes
execlp("/bin/sh","/bin/sh", "-c", "ls -l /bin/??", (char *)NULL);
Side note:
The /bin/??
is doing pattern matching, this pattern matching is done by the shell, and it expands to all files under /bin/ with 2 characters. If you simply did
execlp("ls","ls", "-l", "/bin/??", (char *)NULL);
Probably nothing would happen (unless there's a file actually named /bin/??
) as there's no shell that interprets and expands /bin/??
Something like this in your form main. Double click the form in the visual editor to create the form load event.
Timer Clock=new Timer();
Clock.Interval=2700000; // not sure if this length of time will work
Clock.Start();
Clock.Tick+=new EventHandler(Timer_Tick);
Then add an event handler to do something when the timer fires.
public void Timer_Tick(object sender,EventArgs eArgs)
{
if(sender==Clock)
{
// do something here
}
}
Instead of doing file_put_contents(***WebSiteURL***...)
you need to use the server path to /cache/lang/file.php
(e.g. /home/content/site/folders/filename.php
).
You cannot open a file over HTTP
and expect it to be written. Instead you need to open it using the local path.
You can use the round
function to compute the value.
Yes in python as many have pointed when we compute the value of a cube root, it will give you an output with a little bit of error. To check if the value is a whole number you can use the following function:
def cube_integer(n):
if round(n**(1.0/3.0))**3 == n:
return True
return False
But remember that int(n)
is equivalent to math.floor
and because of this if you find the int(41063625**(1.0/3.0))
you will get 344 instead of 345.
So please be careful when using int
withe cube roots.
Here's what happened to me: the server was returning a malformed "Location" header for a 302 redirect. Chrome failed to tell me this, of course. I opened the page in firefox, and immediately discovered the problem. Nice to have multiple tools :)
You can easily install 1.8 via PPA. Which can be done by:
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer
Then check the running version:
$ java -version
If you must do it manually there's already an answer for that on AskUbuntu here.
The best thing to do is to remove Node.js from the control panel. Once deleted download the desired version of Node.js and install it and it works.
Though there are so many good answers, here is my two cents for the future me :P and for anyone who wants it quick and easy.
For Mac:
open terminal and run the following script
adb tcpip 5555
adb connect $(adb shell ifconfig | grep "inet " | grep -v 127.0.0.1 | awk '{print $2}' | cut -d: -f2):5555
Explanation:
adb tcpip 5555
commands the device to start listening for connections on port 5555
adb connect $(_ip_address_fetched_):5555
tells to connect on port 5555 of the _ip_address_fetched_
address
where _ip_address_fetched_
includes following:
adb shell ifconfig
getting internet configurations using adb shell
grep "inter "
filter any line that starts with inter
grep -v 127.0.0.1
exclude localhost.
At this point, output should be like:
inet addr:###.###.#.### Bcast:###.###.#.### Mask:255.255.255.0
awk '{print $2}'
get the second part of the components array, separated by space (I'm using zsh).
The output up to this point is
addr:###.###.#.###
cut -d: -f2
split the string by delimiter : and take second part. It will only take your device IP address
There's nothing wrong with include file in head. It seems you forgot to add;
. Please try this one:
<body onload="imageRefreshBig();">
But as per my knowledge semicolons are optional. You can try with ;
but better debug code and see if chrome console gives any error.
I hope this helps.
_.each(['Hello', 'World!'], function(word){_x000D_
console.log(word);_x000D_
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
_x000D_
Here's simple example that could use _.each
:
function basket() {_x000D_
this.items = [];_x000D_
this.addItem = function(item) {_x000D_
this.items.push(item);_x000D_
};_x000D_
this.show = function() {_x000D_
console.log('items: ', this.items);_x000D_
}_x000D_
}_x000D_
_x000D_
var x = new basket();_x000D_
x.addItem('banana');_x000D_
x.addItem('apple');_x000D_
x.addItem('kiwi');_x000D_
x.show();
_x000D_
Output:
items: [ 'banana', 'apple', 'kiwi' ]
Instead of calling addItem
multiple times you could use underscore this way:
_.each(['banana', 'apple', 'kiwi'], function(item) { x.addItem(item); });
which is identical to calling addItem
three times sequentially with these items. Basically it iterates your array and for each item calls your anonymous callback function that calls x.addItem(item)
. The anonymous callback function is similar to addItem
member function (e.g. it takes an item) and is kind of pointless. So, instead of going through anonymous function it's better that _.each
avoids this indirection and calls addItem
directly:
_.each(['banana', 'apple', 'kiwi'], x.addItem);
but this won't work, as inside basket's addItem
member function this
won't refer to your x
basket that you created. That's why you have an option to pass your basket x
to be used as [context]
:
_.each(['banana', 'apple', 'kiwi'], x.addItem, x);
function basket() {_x000D_
this.items = [];_x000D_
this.addItem = function(item) {_x000D_
this.items.push(item);_x000D_
};_x000D_
this.show = function() {_x000D_
console.log('items: ', this.items);_x000D_
}_x000D_
}_x000D_
var x = new basket();_x000D_
_.each(['banana', 'apple', 'kiwi'], x.addItem, x);_x000D_
x.show();
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
_x000D_
In short, if callback function that you pass to _.each
in any way uses this
then you need to specify what this
should be referring to inside your callback function. It may seem like x
is redundant in my example, but x.addItem
is just a function and could be totally unrelated to x
or basket
or any other object, for example:
function basket() {_x000D_
this.items = [];_x000D_
this.show = function() {_x000D_
console.log('items: ', this.items);_x000D_
}_x000D_
}_x000D_
function addItem(item) {_x000D_
this.items.push(item);_x000D_
};_x000D_
_x000D_
var x = new basket();_x000D_
_.each(['banana', 'apple', 'kiwi'], addItem, x);_x000D_
x.show();
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
_x000D_
In other words, you bind some value to this
inside your callback, or you may as well use bind directly like this:
_.each(['banana', 'apple', 'kiwi'], addItem.bind(x));
how this feature can be useful with some different underscore methods?
In general, if some underscorejs
method takes a callback function and if you want that callback be called on some member function of some object (e.g. a function that uses this
) then you may bind that function to some object or pass that object as the [context]
parameter and that's the primary intention. And at the top of underscorejs documentation, that's exactly what they state: The iteratee is bound to the context object, if one is passed
The "timeit" answer above that declares divmod to be slower has seriously flawed logic.
Test1 calls operators.
Test2 calls the function divmod, and calling a function has overhead.
A more accurate way to test would be:
import timeit
def moddiv(a,b):
q= a/b
r= a%b
return q,r
a=10
b=3
md=0
dm=0
for i in range(1,10):
c=a*i
md+= timeit.timeit( lambda: moddiv(c,b))
dm+=timeit.timeit( lambda: divmod(c,b))
print("moddiv ", md)
print("divmod ", dm)
moddiv 5.806157339000492
divmod 4.322451676005585
divmod is faster.
Since @Doua Beri is experiencing connection close even when there are 1 Hz SENDs, it may be instead be due to size limits on messages.
This passage from Spring's WebSockets may be useful, with my emphasis ...
Although in theory a WebSocket message can be almost unlimited in size, in practice WebSocket servers impose limits — for example, 8K on Tomcat and 64K on Jetty. For this reason STOMP clients such as stomp.js split larger STOMP messages at 16K boundaries and send them as multiple WebSocket messages thus requiring the server to buffer and re-assemble.

I think I remember seeing before that if you are updating to the same value SQL Server will actually recognize this and won't do an unnecessary write.
Although the CONVERT thing works, you actually shouldn't use it. You should ask yourself why you are parsing string values in SQL-Server. If this is a one-time job where you are manually fixing some data you won't get that data another time, this is ok, but if any application is using this, you should change something. Best way would be to use the "date" data type. If this is user input, this is even worse. Then you should first do some checking in the client. If you really want to pass string values where SQL-Server expects a date, you can always use ISO format ('YYYYMMDD') and it should convert automatically.
Instead of accepting a self parameter, class methods take a cls parameter that points to the class—and not the object instance—when the method is called. Since the class method only has access to this cls argument, it can’t modify object instance state. That would require access to self . However, class methods can still modify class state that applies across all instances of the class.
-Python Tricks
Since router v4 I am using 'refs' for setting the parent active class:
<ul>
<li>
<NavLink
innerRef={setParentAsActive}
activeClassName="is-active"
to={link}
>
{text}
</NavLink>
</ul>
NavLink
's innerRef
prop accepts callback function, which will receive DOM node as an argument. You can use then any DOM manipulation possible, in this case simply set parent element (<li>
) to have the same class:
const setParentAsActive = node => {
if (node) {
node.parentNode.className = node.className;
}
};
Drawbacks:
<a>
will have unnecessary is-active
class (as you only need it for <li>
), or you can remove this class in the callback func.a
tag inside a span
, your callback will stop working, but it's possible to write more sofisticated DOM traverse functionI know this is an old question but I did it like:
<asp:RadioButtonList runat="server" ID="myrbl" RepeatDirection="Horizontal" CssClass="rbl">
Use this as your class:
.rbl input[type="radio"]
{
margin-left: 10px;
margin-right: 1px;
}
select *
from TABLE_NAME
where dbms_lob.instr(COLUMNNAME,'searchtext') > 0;
I don't think that one is better than the other in general; it depends on how you intend to use it.
’
).In general I would lean more towards using the character because as you point out it is easier to read and type.
I can't comment but don't want to start a new thread. But this isn't working. A simple round trip:
byte[] b = new byte[]{ 0, 0, 0, -127 }; // 0x00000081
String s = new String(b,StandardCharsets.UTF_8); // UTF8 = 0x0000, 0x0000, 0x0000, 0xfffd
b = s.getBytes(StandardCharsets.UTF_8); // [0, 0, 0, -17, -65, -67] 0x000000efbfbd != 0x00000081
I'd need b[] the same array before and after encoding which it isn't (this referrers to the first answer).
I implemented this simple solution that works for me (not yet on production environment):
function verificarNovaVersio() {
var sVersio = localStorage['gcf_versio'+ location.pathname] || 'v00.0.0000';
$.ajax({
url: "./versio.txt"
, dataType: 'text'
, cache: false
, contentType: false
, processData: false
, type: 'post'
}).done(function(sVersioFitxer) {
console.log('Versió App: '+ sVersioFitxer +', Versió Caché: '+ sVersio);
if (sVersio < (sVersioFitxer || 'v00.0.0000')) {
localStorage['gcf_versio'+ location.pathname] = sVersioFitxer;
location.reload(true);
}
});
}
I've a little file located where the html are:
"versio.txt":
v00.5.0014
This function is called in all of my pages, so when loading it checks if the localStorage's version value is lower than the current version and does a
location.reload(true);
...to force reload from server instead from cache.
(obviously, instead of localStorage you can use cookies or other persistent client storage)
I opted for this solution for its simplicity, because only mantaining a single file "versio.txt" will force the full site to reload.
The queryString method is hard to implement and is also cached (if you change from v1.1 to a previous version will load from cache, then it means that the cache is not flushed, keeping all previous versions at cache).
I'm a little newbie and I'd apreciate your professional check & review to ensure my method is a good approach.
Hope it helps.
