I think above examples are correct. but you dont' really need to set
request.setAttribute("selectedDept", selectedDept);
you can reuse that info from JSTL, just do something like this..
<!DOCTYPE html>
<html lang="en">
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<head>
<script src="../js/jquery-1.8.1.min.js"></script>
</head>
<body>
<c:set var="authors" value="aaa,bbb,ccc,ddd,eee,fff,ggg" scope="application" />
<c:out value="Before : ${param.Author}"/>
<form action="TestSelect.action">
<label>Author
<select id="Author" name="Author">
<c:forEach items="${fn:split(authors, ',')}" var="author">
<option value="${author}" ${author == param.Author ? 'selected' : ''}>${author}</option>
</c:forEach>
</select>
</label>
<button type="submit" value="submit" name="Submit"></button>
<Br>
<c:out value="After : ${param.Author}"/>
</form>
</body>

Unpack it and place somewhere you can find it. In my example, I will assume you will place it to C:\Selenium\iexploredriver.exe
Then you have to set it up in the system. Here is the Java code pasted from my Selenium project:
File file = new File("C:/Selenium/iexploredriver.exe");
System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
WebDriver driver = new InternetExplorerDriver();
Basically, you have to set this property before you initialize driver
Reference:
Turns out that the problem was with face that the script was running from a cPanel "email piped to script", so was running as the user, so is was a user problem, but was not affecting the web server at all.
The cause for the user not being able to access the /etc/pki directory was due to them only having jailed ssh access. Once I granted full access, it all worked fine.
Thanks for the info though, Remi.
This is basically a more detailed version of a previous answer.
In your Terminal, go to the location of your utility program, mysqladmin
For example, if you were doing local development and using an application like M/W/XAMP, you might go to the directory:
/Applications/MAMP/Library/bin
This is where mysqladmin resides.
If you're not using an application like MAMP, you may also be able to find your local installation of mysql at: /usr/local/mysql
And then if you go to: /usr/local/mysql/bin/
You are in the directory where mysqladmin resides.
Then, to change the password, you will do the following:
At your Terminal prompt enter the exact command below (aka copy and paste) and press enter. The word "password" is part of the command, so don't be confused and come to the conclusion that you need to replace this word with some password you created previously or want to use in the future. You will have a chance to enter a new password soon enough, but it's not in this first command that you will do that:
./mysqladmin -u root -p password
The Terminal will ask you to enter your original or initial password, not a new one yet. From the above image you provided, it looks like you have one already created, so enter it here:
Enter password:
oldpassword
New password:
newpassword
Confirm new password:
newpassword
Reset or restart your Terminal.
In some cases, as with M/W/XAMP, you will have to update this new password in various files in order to get your application running properly again.
I also had a similar issue. Someone might find what worked for me helpful.
Machine is running Ubuntu 16.04 and has Docker CE. After looking through the answers and links provided here, especially from the link from the Docker website given by Elliot Beach, I opened my /etc/apt/sources.list and examined it.
The file had both deb [arch=amd64] https://download.docker.com/linux/ubuntu (lsb_release -cs) stable
and deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable
.
Since the second one was what was needed, I simply commented out the first, saved the document and now the issue is fixed. As a test, I went back into the same document, removed the comment sign and ran sudo apt-get update
again. The issue returned when I did that.
So to recap : not only did I have my parent Ubuntu distribution name as stated on the Docker website but I also commented out the line still containing (lsb_release -cs).
For those using ASP.NET MVC,
Needing to move the modal div just before the </body>
tag but can't do it because you are using a Layout page
Define a section in you _Layout.cshtml
file just before the body tag, eg:
... some html in layout page ...
@RenderSection("bottomHTML", required: false)
</body>
</html>
Then in your view
@section bottomHTML
{
<div class="modal fade" id="myModalID" role="dialog" tabindex="-1" aria-labelledby="demo-default-modal" aria-hidden="true">
... rest of the modal div HTML ...
}
This way, the modal HTML will be rendered before the body tag and the modal now should be displayed correctly..
This may resolve everyones problem: All tags are added so you don't need to worry about folders path. Replace res/xml/file_paths.xml with:
<?xml version="1.0" encoding="utf-8"?>

<external-files-path

I tried and found out that if you add a class called btn
you can get that hand
or cursor
icon if you hover over the mouse to that element. Try and see.
Example:
<span class="btn">Hovering over must have mouse cursor set to hand or pointer!</span>

You can set the cookie after having checked if it exists with a value.
$(document).ready(function(){
if ($.cookie('cookie')) { //if cookie isset
//do stuff here like hide a popup when cookie isset
//document.getElementById("hideElement").style.display = "none";
}else{
var CookieSet = $.cookie('cookie', 'value'); //set cookie
}
});

private fun setLocale(activity: Activity, languageCode: String?) {
val locale = Locale(languageCode)
Locale.setDefault(locale)
val config: Configuration = resources.configuration
config.setLocale(locale)

kwargs is just a dictionary that is added to the parameters.
A dictionary can contain key, value pairs. And that are the kwargs. Ok, this is how.
The what for is not so simple.
For example (very hypothetical) you have an interface that just calls other routines to do the job:
def myDo(what, where, why):
if what == 'swim':
doSwim(where, why)
elif what == 'walk':
doWalk(where, why)
...
Now you get a new method "drive":
elif what == 'drive':
doDrive(where, why, vehicle)
But wait a minute, there is a new parameter "vehicle" -- you did not know it before. Now you must add it to the signature of the myDo-function.
Here you can throw kwargs into play -- you just add kwargs to the signature:
def myDo(what, where, why, **kwargs):
if what == 'drive':
doDrive(where, why, **kwargs)
elif what == 'swim':
doSwim(where, why, **kwargs)
This way you don't need to change the signature of your interface function every time some of your called routines might change.
This is just one nice example you could find kwargs helpful.
I had a workaround for this problem. I created dll project with viewer in vs2015 and used this dll in vs2017. Report showing perfectly.
You can try this:
SELECT * FROM MYTABLE WHERE DATE BETWEEN '03/10/2014 06:25:00' and '03/12/2010 6:25:00'
You can do this for webkit:
#text2::-webkit-input-placeholder::before {
color:#666;
content:"Line 1\A Line 2\A Line 3\A";
}
For that ratio of read/writes I would guess InnoDB will perform better. Since you are fine with dirty reads, you might (if you afford) replicate to a slave and let all your reads go to the slave. Also, consider inserting in bulk, rather than one record at a time.
For compatibility with Tensorflow 2.0, you can use tf.get_logger
import logging
tf.get_logger().setLevel(logging.ERROR)
apt-get install tig
While inside a git repo, type 'tig', to view an interactive log, hit 'enter' on any log to see more information about it. h for help, which lists the basic functionality.
"Tig" is "Git" backwards.
http://www.connectionstrings.com is a site where you can find a lot of connection strings. All that you need to do is copy-paste and modify it to suit your needs. It is sure to have all the connection strings for all of your needs.
I know it's an old question and Path.GetFileNameWithoutExtension
is a better and maybe cleaner option. But personally I've added this two methods to my project and wanted to share them. This requires C# 8.0 due to it using ranges and indices.
public static string RemoveExtension(this string file) => ReplaceExtension(file, null);
public static string ReplaceExtension(this string file, string extension)
{
var split = file.Split('.');
if (string.IsNullOrEmpty(extension))
return string.Join(".", split[..^1]);
split[^1] = extension;
return string.Join(".", split);
}
You should use "text/csv" according to RFC 4180.
You can return FileResult with this methods:
1: Return FileStreamResult
[HttpGet("get-file-stream/{id}"]
public async Task<FileStreamResult> DownloadAsync(string id)
{
var fileName="myfileName.txt";
var mimeType="application/....";
var stream = await GetFileStreamById(id);
return new FileStreamResult(stream, mimeType)
{
FileDownloadName = fileName
};
}
2: Return FileContentResult
[HttpGet("get-file-content/{id}"]
public async Task<FileContentResult> DownloadAsync(string id)
{
var fileName="myfileName.txt";
var mimeType="application/....";
var fileBytes = await GetFileBytesById(id);
return new FileContentResult(fileBytes, mimeType)
{
FileDownloadName = fileName
};
}
I think it boils down to a personal preference.
Do you want to hide your silly mistakes before pushing your changes? If so, git pull --rebase
is perfect. It allows you to later squash your commits to a few (or one) commits. If you have merges in your (unpushed) history, it is not so easy to do a git rebase
later one.
I personally don't mind publishing all my silly mistakes, so I tend to merge instead of rebase.
You can use the resulting xaml from the SVG as a drawing brush on a rectangle. Something like this:

--- insert the converted xaml's geometry here ---
</Rectangle.Fill>

cal = 123.4567
print(f"result {cal:.4E}")

indicates how many digits are shown shown in the floating part.
cal = 123.4567
totalDigitInFloatingPArt = 4
print(f"result {cal:.{totalDigitInFloatingPArt}E} ")
open node.js command prompt

When you use df.apply()
, each row of your DataFrame will be passed to your lambda function as a pandas Series. The frame's columns will then be the index of the series and you can access values using series[label]
.
So this should work:
df['D'] = (df.apply(lambda x: myfunc(x[colNames[0]], x[colNames[1]]), axis=1))
Though is answered in another stack overflow question Bind a function to Twitter Bootstrap Modal Close but for visual feel here is more detailed answer.
mkdir()
creates only one directory at a time, if it is parent that one only. other wise it can create the sub directory(if the specified path is existed only) and do not create any directories in between any two directories. so it can not create smultiple directories in one directory
mkdirs()
create the multiple directories(in between two directories also) at a time.
Just for completeness, you can use the standard library and do QString qstr = QString::fromStdString(std::to_string(42));
I had this requirement: Changing programmatically the status bar color keeping it transparent, to allow the Navigation Drawer to draw itself overlapping the trasparent status bar.
I cannot do that using the API
getWindow().setStatusBarColor(ContextCompat.getColor(activity ,R.color.my_statusbar_color)
If you check here in stack overflow everyone before that line of code set the transparency of the status bar to solid with
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
I'm able to manage color and transparency of status bar like this:
Android 4: there's not much you can do, because you can't manage status bar color from the API ... the only thing you can do is to set the status bar as translucent and move a colored element of you UI under the status bar. To do this you need to play with
android:fitsSystemWindows="false"
in your main layout. This allows you to draw you layout under the status bar. Then you need to play with some padding with the top of your main layout.
Android 5 and above: you have to define a style with
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
this allows the navigation drawer to overlap the status bar.
Then to change the color keeping the status bar transparent you have to set the status bar color with
drawerLayout.setStatusBarBackgroundColor(ContextCompat.getColor(activity, R.color.my_statusbar_color))
where drawerLayout is defined like this
<android.support.v4.widget.DrawerLayout
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
Ar you looking for that:
isEmptyObject(obj) {
return (obj && (Object.keys(obj).length === 0));
}

or that :
function isEmpty(obj) {
for(var key in obj) {
if(obj.hasOwnProperty(key))
return false;
}
return true;
}

You can use org.apache.commons.math.util.MathUtils from apache common
double round = MathUtils.round(double1, 2, BigDecimal.ROUND_HALF_DOWN);
If you use MVC 3 and .NET 4, you can use the new Display
attribute in the System.ComponentModel.DataAnnotations
namespace. This attribute replaces the DisplayName
attribute and provides much more functionality, including localization support.
In your case, you would use it like this:
public class MyModel
{
[Required]
[Display(Name = "labelForName", ResourceType = typeof(Resources.Resources))]
public string name{ get; set; }
}
As a side note, this attribute will not work with resources inside App_GlobalResources
or App_LocalResources
. This has to do with the custom tool (GlobalResourceProxyGenerator
) these resources use. Instead make sure your resource file is set to 'Embedded resource' and use the 'ResXFileCodeGenerator' custom tool.
(As a further side note, you shouldn't be using App_GlobalResources
or App_LocalResources
with MVC. You can read more about why this is the case here)
I am sure you would've already found your answer... here is the solution I derived at.

I recently ran into this error on Windows 10. It turned out that windows was looking for .dll files necessary for my project and couldn't find them because it looks for them in the system path, PATH, rather than the CLASSPATH or -Djava.library.path
Open your system command prompt/terminal -> Go to your Project folder path (root project folder ) -> Execute following command : command :- gradlew clean
or ./gradlew clean
Make sure that all your gradle dependencies are of same version. -> Example :- your appcompat and recyclerview dependencies should have same version.
-> Change your gradle dependencies to same version like :-
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile 'com.android.support:cardview-v7:23.4.0'
-> Rebuild your project and it will work fine.
Try simply to reset last commit using --soft

To tell from the style of your code snippet, I suppose you were using IPython rather than Jupyter Notebook.
In this issue on GitHub, it was made clear by a member of IPython in 2016 that the display of charts would only work when "only work when it's a Jupyter kernel". Thus, the %matplotlib inline
would not work.
I was just having the same issue and suggest you use Jupyter Notebook for the visualization.
Neither a ":" nor a "." will show up in valid Base64, so I think you can unambiguously throw away the http://www.stackoverflow.com
line. In Perl, say, something like
my $sanitized_str = join q{}, grep {!/[^A-Za-z0-9+\/=]/} split /\n/, $str;
say decode_base64($sanitized_str);
might be what you want. It produces
This is simple ASCII Base64 for StackOverflow exmaple.
Use file_get_contents
in combination with json_decode
and echo

>>> import random
>>> d = dict(Venezuela = 1, Spain = 2, USA = 3, Italy = 4)
>>> random.choice(d.keys())
'Venezuela'
>>> random.choice(d.keys())
'USA'
By calling random.choice on the keys
of the dictionary (the countries).
Make sure to target x86 on your project in Visual Studio. This should fix your trouble.
Promises
don't "return" values, they pass them to a callback (which you supply with .then()).
It's probably trying to say that you're supposed to do resolve(someObject);
inside the promise implementation.
Then in your then
code you can reference someObject
to do what you want.

Laravel 5 ships with a Bootstrap 4 paginator if anyone needs it.
First create a new service provider.
php artisan make:provider PaginationServiceProvider
In the register
method pass a closure to Laravel's paginator class that creates and returns the new presenter.
<?php
namespace App\Providers;
use Illuminate\Pagination\BootstrapFourPresenter;
use Illuminate\Pagination\Paginator;
use Illuminate\Support\ServiceProvider;
class PaginationServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* @return void
*/
public function boot()
{
//
}
/**
* Register the application services.
*
* @return void
*/
public function register()
{
Paginator::presenter(function($paginator)
{
return new BootstrapFourPresenter($paginator);
});
}
}
Register the new provider in config/app.php
'providers' => [
//....
App\Providers\PaginationServiceProvider::class,
]
I found this example at Bootstrap 4 Pagination With Laravel
I've had great success with wsdl2php. It will automatically create wrapper classes for all objects and methods used in your web service.

Link PYTHONSTARTUP
to a python file with the following
# Make exit work as expected
type(exit).__repr__ = type(exit).__call__
How does this work?
The python command line is a read-evaluate-print-loop, that is when you type text it will read that text, evaluate it, and eventually print the result.
When you type exit()
it evaluates to a callable object of type site.Quitter
and calls its __call__
function which exits the system. When you type exit
it evaluates to the same callable object, without calling it the object is printed which in turn calls __repr__
on the object.
We can take advantage of this by linking __repr__
to __call__
and thus get the expected behavior of exiting the system even when we type exit
without parentheses.
Try (in your <head> section, or existing css definitions)...

There is no correct answer, since it depends on what the definition of "syntax" is for your request. The most important thing is that you:
Before everyone jumps all over me for saying that there is no right or wrong answer here, let me explain a bit about how I came to the conclusion.
In this specific example, the OP's question is about a JSON request that contains a different key than expected. Now, the key name received is very similar, from a natural language standpoint, to the expected key, but it is, strictly, different, and hence not (usually) recognized by a machine as being equivalent.
As I said above, the deciding factor is what is meant by syntax. If the request was sent with a Content Type of application/json
, then yes, the request is syntactically valid because it's valid JSON syntax, but not semantically valid, since it doesn't match what's expected. (assuming a strict definition of what makes the request in question semantically valid or not).
If, on the other hand, the request was sent with a more specific custom Content Type like application/vnd.mycorp.mydatatype+json
that, perhaps, specifies exactly what fields are expected, then I would say that the request could easily be syntactically invalid, hence the 400 response.
In the case in question, since the key was wrong, not the value, there was a syntax error if there was a specification for what valid keys are. If there was no specification for valid keys, or the error was with a value, then it would be a semantic error.
to escape non-alphanumeric characters of string variables, including dots, you could use re.escape
:
import re
expression = 'whatever.v1.dfc'
escaped_expression = re.escape(expression)
print(escaped_expression)
output:
whatever\.v1\.dfc
you can use the escaped expression to find/match the string literally.

In Java 8 atomic classes have been extended with two interesting functions:
Both are using the updateFunction to perform update of the atomic value. The difference is that the first one returns old value and the second one return the new value. The updateFunction may be implemented to do more complex "compare and set" operations than the standard one. For example it can check that atomic counter doesn't go below zero, normally it would require synchronization, and here the code is lock-free:
public class Counter {
private final AtomicInteger number;
public Counter(int number) {
this.number = new AtomicInteger(number);
}
/** @return true if still can decrease */
public boolean dec() {
// updateAndGet(fn) executed atomically:
return number.updateAndGet(n -> (n > 0) ? n - 1 : n) > 0;
}
}
The code is taken from Java Atomic Example.
You shouldn't need a $watch. Just bind to resize event on window:
'use strict';
var app = angular.module('plunker', []);
app.directive('myDirective', ['$window', function ($window) {
return {
link: link,
restrict: 'E',
template: '<div>window size: {{width}}px</div>'
};
function link(scope, element, attrs){
scope.width = $window.innerWidth;
angular.element($window).bind('resize', function(){
scope.width = $window.innerWidth;
// manuall $digest required as resize event
// is outside of angular
scope.$digest();
});
}
}]);

<?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"','''')"/> </xsl:template> </xsl:stylesheet>
Doing it in XSLT1 is a little more problematic as it's hard to get a literal containing a single apostrophe, so you have to resort to a variable:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:variable name="apos">'</xsl:variable> <xsl:template match="text()"> <xsl:value-of select="translate(.,'"',$apos)"/> </xsl:template> </xsl:stylesheet>
if num in range(min, max):
"""do stuff..."""
else:
"""do other stuff..."""
Here is a code sample which should pretty much sum this up for you... In addition to the below, showing how you can't access a default in another package there is one more thing.
Default is not accessible in a subclass if the class that subclasses it is in another package, but it is accessible if the subclass is in the same package.
package main;
public class ClassA {
private int privateVar;
public int publicVar;
int defaultVar;
}
package main;
public class ClassB {
public static void main(String[] args) {
ClassA a = new ClassA();
int v1 = a.publicVar; // Works
int v2 = a.defaultVar; // Works
int v3 = a.privateVar; // Doesn't work
}
}
package other;
public class ClassC {
public static void main(String[] args) {
ClassA a = new ClassA();
int v1 = a.publicVar; // Works
int v2 = a.defaultVar; // Doesn't work
int v3 = a.privateVar; // Doesn't work
}
}
getContentResolver()
is method of class android.content.Context
, so to call it you definitely need an instance
of Context ( Activity or Service for example).
Java doesn't do anything with integer overflow for either int or long primitive types and ignores overflow with positive and negative integers.
This answer first describes the of integer overflow, gives an example of how it can happen, even with intermediate values in expression evaluation, and then gives links to resources that give detailed techniques for preventing and detecting integer overflow.
Integer arithmetic and expressions reslulting in unexpected or undetected overflow are a common programming error. Unexpected or undetected integer overflow is also a well-known exploitable security issue, especially as it affects array, stack and list objects.
Overflow can occur in either a positive or negative direction where the positive or negative value would be beyond the maximum or minimum values for the primitive type in question. Overflow can occur in an intermediate value during expression or operation evaluation and affect the outcome of an expression or operation where the final value would be expected to be within range.
Sometimes negative overflow is mistakenly called underflow. Underflow is what happens when a value would be closer to zero than the representation allows. Underflow occurs in integer arithmetic and is expected. Integer underflow happens when an integer evaluation would be between -1 and 0 or 0 and 1. What would be a fractional result truncates to 0. This is normal and expected with integer arithmetic and not considered an error. However, it can lead to code throwing an exception. One example is an "ArithmeticException: / by zero" exception if the result of integer underflow is used as a divisor in an expression.
Consider the following code:
int bigValue = Integer.MAX_VALUE;
int x = bigValue * 2 / 5;
int y = bigValue / x;
which results in x being assigned 0 and the subsequent evaluation of bigValue / x throws an exception, "ArithmeticException: / by zero" (i.e. divide by zero), instead of y being assigned the value 2.
The expected result for x would be 858,993,458 which is less than the maximum int value of 2,147,483,647. However, the intermediate result from evaluating Integer.MAX_Value * 2, would be 4,294,967,294, which exceeds the maximum int value and is -2 in accordance with 2s complement integer representations. The subsequent evaluation of -2 / 5 evaluates to 0 which gets assigned to x.
Rearranging the expression for computing x to an expression that, when evaluated, divides before multiplying, the following code:
int bigValue = Integer.MAX_VALUE;
int x = bigValue / 5 * 2;
int y = bigValue / x;
results in x being assigned 858,993,458 and y being assigned 2, which is expected.
The intermediate result from bigValue / 5 is 429,496,729 which does not exceed the maximum value for an int. Subsequent evaluation of 429,496,729 * 2 doesn't exceed the maximum value for an int and the expected result gets assigned to x. The evaluation for y then does not divide by zero. The evaluations for x and y work as expected.
Java integer values are stored as and behave in accordance with 2s complement signed integer representations. When a resulting value would be larger or smaller than the maximum or minimum integer values, a 2's complement integer value results instead. In situations not expressly designed to use 2s complement behavior, which is most ordinary integer arithmetic situations, the resulting 2s complement value will cause a programming logic or computation error as was shown in the example above. An excellent Wikipedia article describes 2s compliment binary integers here: Two's complement - Wikipedia
There are techniques for avoiding unintentional integer overflow. Techinques may be categorized as using pre-condition testing, upcasting and BigInteger.
Pre-condition testing comprises examining the values going into an arithmetic operation or expression to ensure that an overflow won't occur with those values. Programming and design will need to create testing that ensures input values won't cause overflow and then determine what to do if input values occur that will cause overflow.
Upcasting comprises using a larger primitive type to perform the arithmetic operation or expression and then determining if the resulting value is beyond the maximum or minimum values for an integer. Even with upcasting, it is still possible that the value or some intermediate value in an operation or expression will be beyond the maximum or minimum values for the upcast type and cause overflow, which will also not be detected and will cause unexpected and undesired results. Through analysis or pre-conditions, it may be possible to prevent overflow with upcasting when prevention without upcasting is not possible or practical. If the integers in question are already long primitive types, then upcasting is not possible with primitive types in Java.
The BigInteger technique comprises using BigInteger for the arithmetic operation or expression using library methods that use BigInteger. BigInteger does not overflow. It will use all available memory, if necessary. Its arithmetic methods are normally only slightly less efficient than integer operations. It is still possible that a result using BigInteger may be beyond the maximum or minimum values for an integer, however, overflow will not occur in the arithmetic leading to the result. Programming and design will still need to determine what to do if a BigInteger result is beyond the maximum or minimum values for the desired primitive result type, e.g., int or long.
The Carnegie Mellon Software Engineering Institute's CERT program and Oracle have created a set of standards for secure Java programming. Included in the standards are techniques for preventing and detecting integer overflow. The standard is published as a freely accessible online resource here: The CERT Oracle Secure Coding Standard for Java
The standard's section that describes and contains practical examples of coding techniques for preventing or detecting integer overflow is here: NUM00-J. Detect or prevent integer overflow
Book form and PDF form of The CERT Oracle Secure Coding Standard for Java are also available.
Or git stash (if you have changes) on the branch you're on, checkout master, pull for the latest changes, grab that file to your desktop (or the entire app). Checkout the branch you were on. Git stash apply back to the state you were at, then fix the changes manually or drag it replacing the file.
This way is not sooooo cool but it def works if you guys can't figure anything else out.
You have two possibilities.
C:\path\to\xml\file.xml
Start Menu > Programs > Microsoft Visual Studio 2012 > Visual Studio Tools
Or if you have Windows 8 can just start typing Developer Command Prompt in Start screencd /D "C:\path\to\xml"
xsd file.xml
xsd /c file.xsd
And that's it! You have generated C# classes from xml file in C:\path\to\xml\file.cs
Edit > Paste special > Paste XML As Classes
And that's it!
Usage is very simple with this helper class:
using System;
using System.IO;
using System.Web.Script.Serialization; // Add reference: System.Web.Extensions
using System.Xml;
using System.Xml.Serialization;
namespace Helpers
{
internal static class ParseHelpers
{
private static JavaScriptSerializer json;
private static JavaScriptSerializer JSON { get { return json ?? (json = new JavaScriptSerializer()); } }
public static Stream ToStream(this string @this)
{
var stream = new MemoryStream();
var writer = new StreamWriter(stream);
writer.Write(@this);
writer.Flush();
stream.Position = 0;
return stream;
}
public static T ParseXML<T>(this string @this) where T : class
{
var reader = XmlReader.Create(@this.Trim().ToStream(), new XmlReaderSettings() { ConformanceLevel = ConformanceLevel.Document });
return new XmlSerializer(typeof(T)).Deserialize(reader) as T;
}
public static T ParseJSON<T>(this string @this) where T : class
{
return JSON.Deserialize<T>(@this.Trim());
}
}
}
All you have to do now, is:
public class JSONRoot
{
public catalog catalog { get; set; }
}
// ...
string xml = File.ReadAllText(@"D:\file.xml");
var catalog1 = xml.ParseXML<catalog>();
string json = File.ReadAllText(@"D:\file.json");
var catalog2 = json.ParseJSON<JSONRoot>();
View.GONE makes the view invisible without the view taking up space in the layout. View.INVISIBLE makes the view just invisible still taking up space.
You are first using GONE and then INVISIBLE on the same view.Since, the code is executed sequentially, first the view becomes GONE then it is overridden by the INVISIBLE type still taking up space.
You should add button listener on the button and inside the onClick() method make the views visible. This should be the logic according to me in your onCreate() method.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_setting);
final DatePicker dp2 = (DatePicker) findViewById(R.id.datePick2);
final Button btn2 = (Button) findViewById(R.id.btnDate2);
final Button btn3 = (Button) findViewById(R.id.btnVisibility);
dp2.setVisibility(View.INVISIBLE);
btn2.setVisibility(View.INVISIBLE);
bt3.setOnClickListener(new View.OnCLickListener(){
@Override
public void onClick(View view)
{
dp2.setVisibility(View.VISIBLE);
bt2.setVisibility(View.VISIBLE);
}
});
}
I think this should work easily. Hope this helps.

Passing data from PHP is easy, you can generate JavaScript with it. The other way is a bit harder - you have to invoke the PHP script by a Javascript request.
An example (using traditional event registration model for simplicity):
<!-- headers etc. omitted -->
<script>
function callPHP(params) {
var httpc = new XMLHttpRequest(); // simplified for clarity
var url = "get_data.php";
httpc.open("POST", url, true); // sending as POST
httpc.onreadystatechange = function() { //Call a function when the state changes.
if(httpc.readyState == 4 && httpc.status == 200) { // complete and no errors
alert(httpc.responseText); // some processing here, or whatever you want to do with the response
}
};
httpc.send(params);
}
</script>
<a href="#" onclick="callPHP('lorem=ipsum&foo=bar')">call PHP script</a>
<!-- rest of document omitted -->
Whatever get_data.php
produces, that will appear in httpc.responseText. Error handling, event registration and cross-browser XMLHttpRequest compatibility are left as simple exercises to the reader ;)

A litte late answer.
If you want to use a grid like this, you should have a look at Bootstrap, It's relatively easy to install, and it gives you exactly what you are looking for, all wrapped in nice and simple html/css + it works easily for making websites responsive.
// this will give all the forms on the page.
$('form')
// If you know the name of form then.
$('form[name="myFormName"]')
// If you don't know know the name but the position (starts with 0)
$('form:eq(1)') // 2nd form will be fetched.
The answer for git branch -r --contains <commit>
works well for normal remote branches, but if the commit is only in the hidden head
namespace that GitHub creates for PRs, you'll need a few more steps.
Say, if PR #42 was from deleted branch and that PR thread has the only reference to the commit on the repo, git branch -r
doesn't know about PR #42 because refs like refs/pull/42/head
aren't listed as a remote branch by default.
In .git/config
for the [remote "origin"]
section add a new line:
fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
(This gist has more context.)
Then when you git fetch
you'll get all the PR branches, and when you run git branch -r --contains <commit>
you'll see origin/pr/42
contains the commit.
As soon as signed and unsigned ints are mixed in an expression things start to get messy and you probably will lose information. Restricting Java to signed ints only really clears things up. I’m glad I don’t have to worry about the whole signed/unsigned business, though I sometimes do miss the 8th bit in a byte.
Swift 4.2 example:
let group = DispatchGroup.group(count: 2)
group.notify(queue: DispatchQueue.main) {
self.renderingLine = false
// all groups are done
}
DispatchQueue.main.async {
self.renderTargetNode(floorPosition: targetPosition, animated: closedContour) {
group.leave()
// first done
}
self.renderCenterLine(position: targetPosition, animated: closedContour) {
group.leave()
// second done
}
}
You could do a simple calculation, pimped with an regex, if the chosen date format is 'YYYYMM':
echo $(($(date +"%Y%m") - 1)) | sed -e 's/99$/12/'
In January of 2020 it will return 201912 ;-) But, it's only a workaround, when date does not have calculation options and other dateinterpreter options (e.g. using perl) not available ;-)

If javascript is accepted as an answer, I made a jQuery plugin to address this issue (for more information about the issue see CSS: Truncate table cells, but fit as much as possible).
To use the plugin just type
$('selector').tableoverflow();

You can also use the Get-Counter cmdlet (PowerShell 2.0):
Get-Counter '\Memory\Available MBytes'
Get-Counter '\Processor(_Total)\% Processor Time'
To get a list of memory counters:
Get-Counter -ListSet *memory* | Select-Object -ExpandProperty Counter
I tried the steps that @KannarKK suggested on ES 2.0.2, however, I could not bring the cluster up and running. Evidently, I figured out something, as I had set tcp port number on Master, on the Slave configuration discovery.zen.ping.unicast.hosts needs Master's port number along with IP address ( tcp port number ) for discovery. So when I try following configuration it works for me.
Node 1
cluster.name: mycluster
node.name: "node1"
node.master: true
node.data: true
http.port : 9200
tcp.port : 9300
discovery.zen.ping.multicast.enabled: false
# I think unicast.host on master is redundant.
discovery.zen.ping.unicast.hosts: ["node1.example.com"]
Node 2
cluster.name: mycluster
node.name: "node2"
node.master: false
node.data: true
http.port : 9201
tcp.port : 9301
discovery.zen.ping.multicast.enabled: false
# The port number of Node 1
discovery.zen.ping.unicast.hosts: ["node1.example.com:9300"]
You can try something like this:
CSS

height:200px;
background: url(img1.png) center center no-repeat;
}
.visited {
background: url(img2.png) center center no-repeat;
}
HTML
<div href="#" onclick="this.className='visited'">

The Date
documentation states that :
The JavaScript date is based on a time value that is milliseconds since midnight January 1, 1970, UTC
Click on start button then on end button. It will show you the number of seconds between the 2 clicks.
The milliseconds diff is in variable timeDiff
. Play with it to find seconds/minutes/hours/ or what you need
var startTime, endTime;_x000D_
_x000D_
function start() {_x000D_
startTime = new Date();_x000D_
};_x000D_
_x000D_
function end() {_x000D_
endTime = new Date();_x000D_
var timeDiff = endTime - startTime; //in ms_x000D_
// strip the ms_x000D_
timeDiff /= 1000;_x000D_
_x000D_
// get seconds _x000D_
var seconds = Math.round(timeDiff);_x000D_
console.log(seconds + " seconds");_x000D_
}
_x000D_
<button onclick="start()">Start</button>_x000D_
_x000D_
<button onclick="end()">End</button>
_x000D_
OR another way of doing it for modern browser
Using performance.now()
which returns a value representing the time elapsed since the time origin. This value is a double with microseconds in the fractional.
The time origin is a standard time which is considered to be the beginning of the current document's lifetime.
var startTime, endTime;_x000D_
_x000D_
function start() {_x000D_

DerivedData
folder (it just contains a cache from previous builds)In my case I also have unmanaged dll's (C++) in workspace and if you specify:
<files>
<file src="bin\*.dll" target="lib" />
</files>
nuget would try to load every dll as an assembly, even the C++ libraries! To avoid this
behaviour explicitly define your C# assemblies with references
tag:
<references>
<reference file="Managed1.dll" />
<reference file="Managed2.dll" />
</references>
Remark: parent of references is metadata -> according to documentation https://docs.microsoft.com/en-us/nuget/reference/nuspec#general-form-and-schema
Documentation: https://docs.microsoft.com/en-us/nuget/reference/nuspec
Write it like this:
string[] files = Directory.GetFiles(@".\Archive", "*.zip");
. is for relative to the folder where you started your exe, and @ to allow \ in the name.
When using filters, you pass it as a second parameter. You can also add a third parameter to specify if you want to search recursively for the pattern.
In order to get the folder where your .exe actually resides, use:
var executingPath = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
Not an answer to your question, but to denote a default char
you can use just
default(char)
which is same as char.MinValue
which in turn is same as \0
. One shouldn't use if for something like an empty string though.
On Route change it will scroll to the top of the page.
$scope.$on('$routeChangeSuccess', function () {
window.scrollTo(0, 0);
});
put this code on your controller.
use default convertation class: Convert.ToDecimal(Double)
Faced the same problem, I simply forgot to activate the transaction management with the @EnableTransactionManagement
annotation.
Ref:
Put this in C2 and copy down
=IF(ISNA(VLOOKUP(A2,$B$2:$B$65535,1,FALSE)),"not in B","")
Then if the value in A isn't in B the cell in column C will say "not in B".
Not possible with vanilla CSS. However you can use something like:
Sass makes CSS fun again. Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.
Or
Rather than constructing long selector names to specify inheritance, in Less you can simply nest selectors inside other selectors. This makes inheritance clear and style sheets shorter.
Example:
#header {
color: red;
a {
font-weight: bold;
text-decoration: none;
}
}
Put something like:
#!/usr/bin/env/python
import sys
if sys.version_info<(2,6,0):
sys.stderr.write("You need python 2.6 or later to run this script\n")
exit(1)
at the top of your script.
Note that depending on what else is in your script, older versions of python than the target may not be able to even load the script, so won't get far enough to report this error. As a workaround, you can run the above in a script that imports the script with the more modern code.
Another technique I just found for solving this (even if I deleted origin first, what appears to be a mistake) is manipulating git config directly:
git config remote.origin.url url-to-my-other-remote

You could always use mysql's LOAD DATA

LOAD DATA LOCAL INFILE '/full/path/to/file/foo.csv' INTO TABLE `footable` FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'
to do bulk inserts rather than using a bunch of INSERT
statements.
There are no problems with the second version of the assignment operator. In fact, that is the standard way for an assignment operator.
Edit: Note that I am referring to the return type of the assignment operator, not to the implementation itself. As has been pointed out in comments, the implementation itself is another issue. See here.

At an outset what I can say is - Agile is an evolutionary methodology from Unified Process which focuses on Iterative & Incremental Development (IID). IID emphasizes iterative development more on construction phases (actual coding) and incremental deliveries. It wouldn't emphasize more on Requirements Analysis (Inception) and Design (Elaboration) being handled in the iterations itself. So, Iteration here is not a "mini project by itself".
In Agile, we take this IDD a bit further, adding more realities like Team Collaboration, Evolutionary Requirements and Design etc. And SCRUM is the tool to enable it by considering the human factors and building around 'Wisdom of the Group' principle. So, Sprint here is a "mini project by itself" bettering a pure IID model.
So, iterations implemented in Agile way are, yes, theoretically Sprints (highlighting the size of the iterations being small and deliveries being quick). I don't really differentiate between Agile and SCRUM and I see that SCRUM is a natural way of putting the Agile principles into use.

Object.Your title question and your example are completely different. I'll start by answering the title question:
$("a").removeAttr("href");
And as far as not requiring an href, the generally accepted way of doing this is:
<a href"#" onclick="doWork(); return false;">link</a>
The return false is necessary so that the href doesn't actually go anywhere.
@[Denys Séguret] has posted correct. But In my case I need new seed everytime hence below code;
Incase you need quick functions. I use like this.
func RandInt(min, max int) int {
r := rand.New(rand.NewSource(time.Now().UnixNano()))
return r.Intn(max-min) + min
}
func RandFloat(min, max float64) float64 {
r := rand.New(rand.NewSource(time.Now().UnixNano()))
return min + r.Float64()*(max-min)
}

You can use JsonConvert from Newtonsoft library. To serialize an object and write to a file in json format:
File.WriteAllText(filePath, JsonConvert.SerializeObject(obj));
And to deserialize it back into object:
var obj = JsonConvert.DeserializeObject<ObjType>(File.ReadAllText(filePath));
Actually your Windows firewall is blocking the connection. You need to enter these commands into cmd.exe
from Administrator.
netsh advfirewall firewall add rule name="FTP" dir=in action=allow program=%SystemRoot%\System32\ftp.exe enable=yes protocol=tcp
netsh advfirewall firewall add rule name="FTP" dir=in action=allow program=%SystemRoot%\System32\ftp.exe enable=yes protocol=udp
In case something goes wrong then you can revert by this:
netsh advfirewall firewall delete rule name="FTP" program=%SystemRoot%\System32\ftp.exe
Yes, first set a datetime to the start of the current month.
Second test if current date day > 25 and get a true/false on that. If True then add add one month to the start of month datetime object. If false then use the datetime object with the value set to the beginning of the month.
import datetime
from dateutil.relativedelta import relativedelta
todayDate = datetime.date.today()
resultDate = todayDate.replace(day=1)
if ((todayDate - resultDate).days > 25):
resultDate = resultDate + relativedelta(months=1)
print resultDate

A bit late in the game but just in case it helps anyone.
If you are testing using the Sandbox and on the payment page you want to test payments NOT using a PayPal account but using the "Pay with Debit or Credit Card option" (i.e. when a regular Joe/Jane, NOT PayPal users, want to buy your stuff) and want to save yourself some time: just go to a site like http://www.getcreditcardnumbers.com/ and get numbers from there. You can use any Expiry date (in the future) and any numeric CCV (123 works).
The "test credit card numbers" in the PayPal documentation are just another brick in their infuriating wall of convoluted stuff.
I got the url above from PayPal's tech support.
Tested using a simple Hosted button and IPN. Good luck.
I prefer TIMESTAMPDIFF because you can easily change the unit if need be.
I like Pedro Ladaria's solution and use something similar.
function strip(number) {
return (parseFloat(number).toPrecision(12));
}
Unlike Pedros solution this will round up 0.999...repeating and is accurate to plus/minus one on the least significant digit.
Note: When dealing with 32 or 64 bit floats, you should use toPrecision(7) and toPrecision(15) for best results. See this question for info as to why.
Here are some tools listed in official python website
There is an app called QPython3 in playstore which can be used for both editing and running python script.
Another app called Termux in which you can install python using command
pkg install python
If you want develop apps , there is Python Android Scripting Layer (SL4A) .
The Scripting Layer for Android, SL4A, is an open source application that allows programs written in a range of interpreted languages to run on Android. It also provides a high level API that allows these programs to interact with the Android device, making it easy to do stuff like accessing sensor data, sending an SMS, rendering user interfaces and so on.
You can also check PySide for Android, which is actually Python bindings for the Qt 4.
There's a platform called PyMob where apps can be written purely in Python and the compiler tool-flow (PyMob) converts them in native source codes for various platforms.
Also check python-for-android
python-for-android is an open source build tool to let you package Python code into standalone android APKs. These can be passed around, installed, or uploaded to marketplaces such as the Play Store just like any other Android app. This tool was originally developed for the Kivy cross-platform graphical framework, but now supports multiple bootstraps and can be easily extended to package other types of Python apps for Android.
Try Chaquopy A Python SDK for Android
Anddd... BeeWare
BeeWare allows you to write your app in Python and release it on multiple platforms. No need to rewrite the app in multiple programming languages. It means no issues with build tools, environments, compatibility, etc.
While binding a databound control, you can evaluate a field of the row in your data source with eval() function.
For example you can add a column to your gridview like that :
<asp:BoundField DataField="YourFieldName" />
And alternatively, this is the way with eval :
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="lbl" runat="server" Text='<%# Eval("YourFieldName") %>'>
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
It seems a little bit complex, but it's flexible, because you can set any property of the control with the eval() function :
<asp:TemplateField>
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%# "ShowDetails.aspx?id="+Eval("Id") %>'
Text='<%# Eval("Text", "{0}") %>'></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
The main thread here seems to be a corrupted user account profile for the account that is used to start the DB engine. This is the account that was specified for the "SQL Server Database" engine during installation. In the setup event log, it's also indicated by the following entry:
SQLSVCACCOUNT: NT AUTHORITY\SYSTEM
According to the link provided by @royki:
The root cause of this issue, in most cases, is that the profile of the user being used for the service account (in my case it was local system) is corrupted.
This would explain why other respondents had success after changing to different accounts:
To fix the user profile that's causing the error, follow the steps listed KB947215.
The main steps from KB947215 are summarized as follows:-
regedit
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
Navigate to the SID for the corrupted profile
To find the SID, click on each SID GUID, review the value for the ProfileImagePath
value, and see if it's the correct account. For system accounts, there's a different way to know the SID for the account that failed:
The main system account SIDs of interest are:
SID Name Also Known As
S-1-5-18 Local System NT AUTHORITY\SYSTEM
S-1-5-19 LocalService NT AUTHORITY\LOCAL SERVICE
S-1-5-20 NetworkService NT AUTHORITY\NETWORK SERVICE
For information on additional SIDs, see Well-known security identifiers in Windows operating systems.

async.waterfall([function(waterCB) {
waterCB(null);
}, function(**inputArray**, waterCB) {

In the above waterfall function, I am accepting inputArray parameter in waterfall 2nd function. But this inputArray not passed in waterfall 1st function in waterCB.
Cheak your function parameters Below are a correct example.
async.waterfall([function(waterCB) {
waterCB(null, **inputArray**);

You are using incorrect overload. You should use this overload
public static MvcHtmlString ActionLink(
this HtmlHelper htmlHelper,
string linkText,
string actionName,
string controllerName,
Object routeValues,
Object htmlAttributes
)
And the correct code would be
<%= Html.ActionLink("Create New Part", "CreateParts", "PartList", new { parentPartId = 0 }, null)%>
Note that extra parameter at the end.
For the other overloads, visit LinkExtensions.ActionLink Method. As you can see there is no string, string, string, object
overload that you are trying to use.
It happens because of the reason mentioned below :
If you see the mvn script: The code fails here ---
Steps for debugging and fixing:
Step 1: Open the mvn script /Users/Username/apache-maven-3.0.5/bin/mvn (Open with the less command like: less /Users/Username/apache-maven-3.0.5/bin/mvn)
Step 2: Find out the below code in the script:
if [ -z "$JAVACMD" ] ; then
if [ -n "$JAVA_HOME" ] ; then
if [ -x "$JAVA_HOME/jre/sh/java" ] ; then
# IBM's JDK on AIX uses strange locations for the executables
JAVACMD="$JAVA_HOME/jre/sh/java"
else
JAVACMD="$JAVA_HOME/bin/java"
fi
else
JAVACMD="`which java`"
fi
fi
if [ ! -x "$JAVACMD" ] ; then
echo "Error: JAVA_HOME is not defined correctly."
echo " We cannot execute $JAVACMD"
exit 1
fi
Step3: It is happening because JAVACMD
variable was not set. So it displays the error.
Note: To Fix it
export JAVACMD=/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/bin/java
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/

Javascript String objects have a split function, doesn't really need to be jQuery specific
var str = "nice.test"
var strs = str.split(".")

I'd be tempted to use JSON in your example though. The php could return the JSON which could easily be parsed
success: function(data) {
var items = JSON.parse(data)
}
From the official documentation regarding the Formatter class:
The constructor takes two optional arguments: a message format string and a date format string.
So change
# create formatter
formatter = logging.Formatter("%(asctime)s;%(levelname)s;%(message)s")
to
# create formatter
formatter = logging.Formatter("%(asctime)s;%(levelname)s;%(message)s",

Your code seems right, check if you have fopen wrappers enabled (allow_url_fopen = On
on php.ini)
Also, as mentioned by other answers, you should provide a properly encoded URI or encode it using urlencode() function. You should also check if there is any error fetching the XML string and if there is any parsing error, which you can output using libxml_get_errors() as follows:
<?php
if (($response_xml_data = file_get_contents($map_url))===false){
echo "Error fetching XML\n";
} else {
libxml_use_internal_errors(true);
$data = simplexml_load_string($response_xml_data);
if (!$data) {
echo "Error loading XML\n";
foreach(libxml_get_errors() as $error) {
echo "\t", $error->message;
}
} else {
print_r($data);
}
}
?>
If the problem is you can't fetch the XML code maybe it's because you need to include some custom headers in your request, check how to use stream_context_create() to create a custom stream context for use when calling file_get_contents()
on example 4 at http://php.net/manual/en/function.file-get-contents.php

I think there is also a possibility to copy the database files from one server to another, but I do not have a server available at the moment so I can't test it.
The first time you run the page, the query_age index doesn't exist because it hasn't been sent over from the form.
When you submit the form it will then exist, and it won't complain about it.
#so change
$_GET['query_age'];
#to:
(!empty($_GET['query_age']) ? $_GET['query_age'] : null);
I suggest a custom alias on you .gitconfig
.
You have to way to do:
1) With git command:
git config --global alias.check-file <command>
2) Editing ~/.gitconfig
and add this line on alias section:
[alias]
check-file = "!f() { if [ $# -eq 0 ]; then echo 'Filename missing!'; else tracked=$(git ls-files ${1}); if [[ -z ${tracked} ]]; then echo 'File not tracked'; else echo 'File tracked'; fi; fi; }; f"
Once launched command (1) or saved file (2), on your workspace you can test it:
$ git check-file
$ Filename missing
$ git check-file README.md
$ File tracked
$ git check-file foo
$ File not tracked

When you use an ORDER BY
clause inside of a sub query used in conjunction with a UNION
mysql will optimise away the ORDER BY
clause.
This is because by default a UNION
returns an unordered list so therefore an ORDER BY
would do nothing.
The optimisation is mentioned in the docs and says:
To apply ORDER BY or LIMIT to an individual SELECT, place the clause inside the parentheses that enclose the SELECT:
(SELECT a FROM t1 WHERE a=10 AND B=1 ORDER BY a LIMIT 10) UNION (SELECT a FROM t2 WHERE a=11 AND B=2 ORDER BY a LIMIT 10);
However, use of ORDER BY for individual SELECT statements implies nothing about the order in which the rows appear in the final result because UNION by default produces an unordered set of rows. Therefore, the use of ORDER BY in this context is typically in conjunction with LIMIT, so that it is used to determine the subset of the selected rows to retrieve for the SELECT, even though it does not necessarily affect the order of those rows in the final UNION result. If ORDER BY appears without LIMIT in a SELECT, it is optimized away because it will have no effect anyway.
The last sentence of this is a bit misleading because it should have an effect. This optimisation causes a problem when you are in a situation where you need to order within the subquery.
To force MySQL to not do this optimisation you can add a LIMIT clause like so:
(SELECT 1 AS rank, id, add_date FROM my_table WHERE distance < 5 ORDER BY add_date LIMIT 9999999999)
UNION ALL
(SELECT 2 AS rank, id, add_date FROM my_table WHERE distance BETWEEN 5 AND 15 ORDER BY rank LIMIT 9999999999)
UNION ALL
(SELECT 3 AS rank, id, add_date from my_table WHERE distance BETWEEN 5 and 15 ORDER BY id LIMIT 9999999999)
A high LIMIT
means that you could add an OFFSET
on the overall query if you want to do something such as pagination.
This also gives you the added benefit of being able to ORDER BY
different columns for each union.
Update for 2020 - BinaryPrimitives
should now be preferred over BitConverter
. It provides endian-specific APIs, and is less allocatey.
byte[] bytes = BitConverter.GetBytes(i);
although note also that you might want to check BitConverter.IsLittleEndian
to see which way around that is going to appear!
Note that if you are doing this repeatedly you might want to avoid all those short-lived array allocations by writing it yourself via either shift operations (>>
/ <<
), or by using unsafe
code. Shift operations also have the advantage that they aren't affected by your platform's endianness; you always get the bytes in the order you expect them.
You already got the right answer, but if you dislike the UIColor
interface like me, you can do this:
#import "UIColor+Helper.h"
// ...
myLabel.textColor = [UIColor colorWithRGBA:0xA06105FF];
UIColor+Helper.h:
#import <UIKit/UIKit.h>
@interface UIColor (Helper)
+ (UIColor *)colorWithRGBA:(NSUInteger)color;
@end
UIColor+Helper.m:
#import "UIColor+Helper.h"
@implementation UIColor (Helper)
+ (UIColor *)colorWithRGBA:(NSUInteger)color
{
return [UIColor colorWithRed:((color >> 24) & 0xFF) / 255.0f
green:((color >> 16) & 0xFF) / 255.0f
blue:((color >> 8) & 0xFF) / 255.0f
alpha:((color) & 0xFF) / 255.0f];
}
@end
In this case you could use basename assuming you have the same suffix on the files you want to remove.
Example:
basename -s .rtf "some string.rtf"
This will return "some string"
If you don't know the suffix, and want it to remove everything after and including the last dot:
f=file.whateverthisis
basename "${f%.*}"
outputs "file"
% means chop, . is what you are chopping, * is wildcard
The short answer is there's no great way to do this given the design you have. Here's a related question on the topic: Sum values of a single row?
If you normalized your schema and created a separate table called "Marks" which had a subject_id and a mark column this would allow you to take advantage of the SUM function as intended by a relational model.
Then your query would be
SELECT subject, SUM(mark) total
FROM Subjects s
INNER JOIN Marks m ON m.subject_id = s.id
GROUP BY s.id
This is usually what I use for counting the number of fields:
head -n 1 file.name | awk -F'|' '{print NF; exit}'
You can use the spread operator (...
) to force it into a new object like this:
axios.get('foo.com')
.then((response) => {})
.catch((error) => {
console.log({...error})
})
Be aware: this will not be an instance of Error.
UPDATE: 9/24/16 Angular 2.0 Stable
This question gets a lot of traffic still, so, I wanted to update it. With the insanity of changes from Alpha, Beta, and 7 RC candidates, I stopped updating my SO answers until they went stable.
This is the perfect case for using Subjects and ReplaySubjects
I personally prefer to use ReplaySubject(1)
as it allows the last stored value to be passed when new subscribers attach even when late:
let project = new ReplaySubject(1);
//subscribe
project.subscribe(result => console.log('Subscription Streaming:', result));
http.get('path/to/whatever/projects/1234').subscribe(result => {
//push onto subject
project.next(result));
//add delayed subscription AFTER loaded
setTimeout(()=> project.subscribe(result => console.log('Delayed Stream:', result)), 3000);
});
//Output
//Subscription Streaming: 1234
//*After load and delay*
//Delayed Stream: 1234
So even if I attach late or need to load later I can always get the latest call and not worry about missing the callback.
This also lets you use the same stream to push down onto:
project.next(5678);
//output
//Subscription Streaming: 5678
But what if you are 100% sure, that you only need to do the call once? Leaving open subjects and observables isn't good but there's always that "What If?"
That's where AsyncSubject comes in.
let project = new AsyncSubject();
//subscribe
project.subscribe(result => console.log('Subscription Streaming:', result),
err => console.log(err),
() => console.log('Completed'));
http.get('path/to/whatever/projects/1234').subscribe(result => {
//push onto subject and complete
project.next(result));
project.complete();
//add a subscription even though completed
setTimeout(() => project.subscribe(project => console.log('Delayed Sub:', project)), 2000);
});
//Output
//Subscription Streaming: 1234
//Completed
//*After delay and completed*
//Delayed Sub: 1234
Awesome! Even though we closed the subject it still replied with the last thing it loaded.
Another thing is how we subscribed to that http call and handled the response. Map is great to process the response.
public call = http.get(whatever).map(res => res.json())
But what if we needed to nest those calls? Yes you could use subjects with a special function:
getThing() {
resultSubject = new ReplaySubject(1);
http.get('path').subscribe(result1 => {
http.get('other/path/' + result1).get.subscribe(response2 => {
http.get('another/' + response2).subscribe(res3 => resultSubject.next(res3))
})
})
return resultSubject;
}
var myThing = getThing();
But that's a lot and means you need a function to do it. Enter FlatMap:
var myThing = http.get('path').flatMap(result1 =>
http.get('other/' + result1).flatMap(response2 =>
http.get('another/' + response2)));
Sweet, the var
is an observable that gets the data from the final http call.
OK thats great but I want an angular2 service!
I got you:
import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { ReplaySubject } from 'rxjs';
@Injectable()
export class ProjectService {
public activeProject:ReplaySubject<any> = new ReplaySubject(1);
constructor(private http: Http) {}
//load the project
public load(projectId) {
console.log('Loading Project:' + projectId, Date.now());
this.http.get('/projects/' + projectId).subscribe(res => this.activeProject.next(res));
return this.activeProject;
}
}
//component
@Component({
selector: 'nav',
template: `<div>{{project?.name}}<a (click)="load('1234')">Load 1234</a></div>`
})
export class navComponent implements OnInit {
public project:any;
constructor(private projectService:ProjectService) {}
ngOnInit() {
this.projectService.activeProject.subscribe(active => this.project = active);
}
public load(projectId:string) {
this.projectService.load(projectId);
}
}
I'm a big fan of observers and observables so I hope this update helps!
Original Answer
I think this is a use case of using a Observable Subject or in Angular2
the EventEmitter
.
In your service you create a EventEmitter
that allows you to push values onto it. In Alpha 45 you have to convert it with toRx()
, but I know they were working to get rid of that, so in Alpha 46 you may be able to simply return the EvenEmitter
.
class EventService {
_emitter: EventEmitter = new EventEmitter();
rxEmitter: any;
constructor() {
this.rxEmitter = this._emitter.toRx();
}
doSomething(data){
this.rxEmitter.next(data);
}
}
This way has the single EventEmitter
that your different service functions can now push onto.
If you wanted to return an observable directly from a call you could do something like this:
myHttpCall(path) {
return Observable.create(observer => {
http.get(path).map(res => res.json()).subscribe((result) => {
//do something with result.
var newResultArray = mySpecialArrayFunction(result);
observer.next(newResultArray);
//call complete if you want to close this stream (like a promise)
observer.complete();
});
});
}
That would allow you do this in the component:
peopleService.myHttpCall('path').subscribe(people => this.people = people);
And mess with the results from the call in your service.
I like creating the EventEmitter
stream on its own in case I need to get access to it from other components, but I could see both ways working...
Here's a plunker that shows a basic service with an event emitter: Plunkr
.html()
only takes a string OR a function as an argument, not both. Try this:
$("#showDiv").click(function () {
$('#theDiv').show(1000, function () {
setTimeout(function () {
$('#theDiv').html(function () {
setTimeout(function () {
$('#theDiv').html('Here is some replacement text');
}, 0);
setTimeout(function () {
$('#theDiv').html('More replacement text goes here');
}, 2500);
});
}, 2500);
});
}); //click function ends
var string = "The dog has a long tail, and it is RED!";
var replaced = string.replace(/ +/g, " ");
Or if you also want to replace tabs:
var replaced = string.replace(/\s+/g, " ");
The Java EE version of Eclipse is not installed, insted a standard SDK version is installed.
You can go to Help > Install New Software then select the Eclipse site from the dropdown (Helios, Kepler depending upon your revision). Then select the option that shows Java EE. Restart Eclipse and you should see the Server list, such as Apache, Oracle, IBM etc.
There's no magical solution of displaying something outside an overflow hidden container.
A similar effect can be achieved by having an absolute positioned div that matches the size of its parent by positioning it inside your current relative container (the div you don't wish to clip should be outside this div):
#1 .mask {
width: 100%;
height: 100%;
position: absolute;
z-index: 1;
overflow: hidden;
}
Take in mind that if you only have to clip content on the x axis (which appears to be your case, as you only have set the div's width), you can use overflow-x: hidden
.
You can simply use decimal.ToString()
For two decimals
myDecimal.ToString("0.00");
For four decimals
myDecimal.ToString("0.0000");
This gives dot as decimal separator, and no thousand separator regardless of culture.
In My case, it was just an extra StackPanel inside the ListView:
<ListView Name="_details" Margin="50,0,50,0">
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Location.LicenseName, StringFormat='Location: {0}'}"/>
<TextBlock Text="{Binding Ticket.Employee.s_name, StringFormat='Served by: {0}'}"/>
<TextBlock Text="{Binding Ticket.dt_create_time, StringFormat='Started at: {0}'}"/>
<Line StrokeThickness="2" Stroke="Gray" Stretch="Fill" Margin="0,5,0,5" />
<ItemsControl ItemsSource="{Binding Items}"/>
</StackPanel>
</StackPanel>
</ListView>
Becomes:
<ListView Name="_details" Margin="50,0,50,0">
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Location.LicenseName, StringFormat='Location: {0}'}"/>
<TextBlock Text="{Binding Ticket.Employee.s_name, StringFormat='Served by: {0}'}"/>
<TextBlock Text="{Binding Ticket.dt_create_time, StringFormat='Started at: {0}'}"/>
<Line StrokeThickness="2" Stroke="Gray" Stretch="Fill" Margin="0,5,0,5" />
<ItemsControl ItemsSource="{Binding Items}"/>
</StackPanel>
</ListView>
and all is well.

CLOCK_REALTIME

This worked for me. It's simple for simple objects.
class Person {_x000D_
constructor(firstName, lastName) {_x000D_
this.firstName = firstName;_x000D_
this.lastName = lastName;_x000D_
}_x000D_
getFullName() {_x000D_
return this.lastName + " " + this.firstName;_x000D_
}_x000D_
_x000D_
static class(obj) {_x000D_
return new Person(obj.firstName, obj.lastName);_x000D_
}_x000D_
}_x000D_
_x000D_
var person1 = {_x000D_
lastName: "Freeman",_x000D_
firstName: "Gordon"_x000D_
};_x000D_
_x000D_
var gordon = Person.class(person1);_x000D_
console.log(gordon.getFullName());
_x000D_
I was also searching for a simple solution, and this is what I came up with, based on all other answers and my research. Basically, class Person has another constructor, called 'class' which works with a generic object of the same 'format' as Person. I hope this might help somebody as well.
The difference is that the uint
and ulong
are unsigned data types, meaning the range is different: They do not accept negative values:
int range: -2,147,483,648 to 2,147,483,647
uint range: 0 to 4,294,967,295

Here you can find a good example of how to format Y-Axis value.
Also, you can use scaleLabel : "<%=value%>"
that you mentioned, It basically means that everything between <%=
and %>
tags will be treated as javascript code (i.e you can use if
statments...)
You may also try contenteditable
attribute onto a normal p
or div
. Not really a textarea
but it will auto-resize without script.
.divtext {
border: ridge 2px;
padding: 5px;
width: 20em;
min-height: 5em;
overflow: auto;
}
_x000D_
<div class="divtext" contentEditable>Hello World</div>
_x000D_

html
<remove ng-repeat-start="itemGroup in Groups" ></remove>
html stuff in here including inner repeating loops if you want
<remove ng-repeat-end></remove>
add an angular.js directive
//remove directive
(function(){
var remove = function(){
return {
restrict: "E",
replace: true,
link: function(scope, element, attrs, controller){
element.replaceWith('<!--removed element-->');
}
};
};
var module = angular.module("app" );
module.directive('remove', [remove]);
}());
for a brief explanation,
ng-repeat binds itself to the <remove>
element and loops as it should, and because we have used ng-repeat-start / ng-repeat-end it loops a block of html not just an element.
then the custom remove directive places the <remove>
start and finish elements with <!--removed element-->
Please careful with $.inArray if you want to use it. I just found out that the $.inArray is only works with "Array", not with String. That's why this function will not working in IE8!
The jQuery API make confusion
The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0
--> They shouldn't say it "Similar". Since indexOf support "String" also!
In your case, the first value to insert must be NULL, because it's AUTO_INCREMENT.

Reinstall numpy-1.11.0_XXX.whl (for your Python) from www.lfd.uci.edu/~gohlke/pythonlibs. This file has the same name and version if compare with the variant downloaded by me earlier 29.03.2016, but its size and content differ from old variant. After re-installation error disappeared.
Second option - return back to scipy 0.17.0 from 0.17.1
P.S. I use Windows 64-bit version of Python 3.5.1, so can't guarantee that numpy for Python 2.7 is already corrected.
Wrap them in another class so that you can end up with a single array or List
of those objects.
public class Data {
private String txtFileName;
private String imgFileName;
// Add/generate c'tor, getter/setter, equals, hashCode and other boilerplate.
}
Usage example:
List<Data> list = new ArrayList<Data>();
list.add(new Data("H1.txt", "e1.jpg"));
list.add(new Data("H2.txt", "e2.jpg"));
// ...
Collections.shuffle(list);

You can wrap the buttons in anchors that href to the appropriate website.
<a href="http://www.stackoverflow.com">
<input type="button" value="Button" />
</a>
<a href="http://www.stackoverflow.com">
<input type="button" value="Button" />
</a>
<a href="http://www.stackoverflow.com">
<input type="button" value="Button" />
</a>
When the user clicks the button (input) they are directed to the destination specified in the href property of the anchor.
Edit: Oops, I didn't read "Eclipse" in the question title. My mistake.
The problem is that MySQL, for whatever inane reason, doesn't allow you to write queries like this:
UPDATE myTable
SET myTable.A =
(
SELECT B
FROM myTable
INNER JOIN ...
)
That is, if you're doing an UPDATE
/INSERT
/DELETE
on a table, you can't reference that table in an inner query (you can however reference a field from that outer table...)
The solution is to replace the instance of myTable
in the sub-query with (SELECT * FROM myTable)
, like this
UPDATE myTable
SET myTable.A =
(
SELECT B
FROM (SELECT * FROM myTable) AS something
INNER JOIN ...
)
This apparently causes the necessary fields to be implicitly copied into a temporary table, so it's allowed.
I found this solution here. A note from that article:
You don’t want to just
SELECT * FROM table
in the subquery in real life; I just wanted to keep the examples simple. In reality, you should only be selecting the columns you need in that innermost query, and adding a goodWHERE
clause to limit the results, too.
Your code is correct. Just test to ensure it is being called like:
<script>
function doIt(){
alert("here i am!");
__doPostBack('ctl00$ctl00$bLogout','')
}
</script>
<iframe onload="doIt()"></iframe>
The command is gradle dependencies

This is a fast way to encode the array, the array shape and the array dtype:
def numpy_to_bytes(arr: np.array) -> str:
arr_dtype = bytearray(str(arr.dtype), 'utf-8')
arr_shape = bytearray(','.join([str(a) for a in arr.shape]), 'utf-8')
sep = bytearray('|', 'utf-8')
arr_bytes = arr.ravel().tobytes()
to_return = arr_dtype + sep + arr_shape + sep + arr_bytes
return to_return
def bytes_to_numpy(serialized_arr: str) -> np.array:
sep = '|'.encode('utf-8')
i_0 = serialized_arr.find(sep)
i_1 = serialized_arr.find(sep, i_0 + 1)
arr_dtype = serialized_arr[:i_0].decode('utf-8')
arr_shape = tuple([int(a) for a in serialized_arr[i_0 + 1:i_1].decode('utf-8').split(',')])
arr_str = serialized_arr[i_1 + 1:]
arr = np.frombuffer(arr_str, dtype = arr_dtype).reshape(arr_shape)
return arr
To use the functions:
a = np.ones((23, 23), dtype = 'int')
a_b = numpy_to_bytes(a)
a1 = bytes_to_numpy(a_b)
np.array_equal(a, a1) and a.shape == a1.shape and a.dtype == a1.dtype

Well as the stack trace says, you would need to set the protected mode settings to same for all zones in IE. Read the why here : http://jimevansmusic.blogspot.in/2012/08/youre-doing-it-wrong-protected-mode-and.html
and a quick how to from the same link : "In IE, from the Tools menu (or the gear icon in the toolbar in later versions), select "Internet options." Go to the Security tab. At the bottom of the dialog for each zone, you should see a check box labeled "Enable Protected Mode." Set the value of the check box to the same value, either checked or unchecked, for each zone"
Try this regular expression:
^(.{0,2}|([^A]..|A[^B].|AB[^C])|.{4,})$
It describes three cases:
A
, orA
but the second is not B
, orA
, the second B
but the third is not C
Check out the ReadKey()
method on the System.Console
.NET class. I think that will do what you're looking for.

Example:
Write-Host -Object ('The key that was pressed was: {0}' -f [System.Console]::ReadKey().Key.ToString());
Don't try and do too much in one step. Keep each rule separate.

errors.push("Your password must be at least 8 characters");
}
if (p.search(/[a-z]/i) < 0) {
errors.push("Your password must contain at least one letter.");
}
if (p.search(/[0-9]/) < 0) {
errors.push("Your password must contain at least one digit.");
}
if (errors.length > 0) {
alert(errors.join("\n"));

@S-Lott gives the right procedure, but expanding on the Unicode issues, the Python interpreter can provide more insights.
Jon Skeet is right (unusual) about the codecs
module - it contains byte strings:
>>> import codecs
>>> codecs.BOM
'\xff\xfe'
>>> codecs.BOM_UTF8
'\xef\xbb\xbf'
>>>
Picking another nit, the BOM
has a standard Unicode name, and it can be entered as:
>>> bom= u"\N{ZERO WIDTH NO-BREAK SPACE}"
>>> bom
u'\ufeff'
It is also accessible via unicodedata
:
>>> import unicodedata
>>> unicodedata.lookup('ZERO WIDTH NO-BREAK SPACE')
u'\ufeff'
>>>
MVVM Model-View ViewModel is similar to MVC, Model-View Controller
The controller is replaced with a ViewModel. The ViewModel sits below the UI layer. The ViewModel exposes the data and command objects that the view needs. You could think of this as a container object that view goes to get its data and actions from. The ViewModel pulls its data from the model.
Russel East does a blog discussing more in detail Why is MVVM is different from MVC

There are more than a few gateways out there, but I am not aware of a reliable gateway that is free. Most gateways like PayPal will provide you APIs that will allow you to process credit cards, as well as do things like void, charge, or refund.
The other thing you need to worry about is the coming of PCI compliance which basically says if you are not compliant, you (or the company you work for) will be liable by your Merchant Bank and/or Card Vendor for not being compliant by July of 2010. This will impose large fines on you and possibly revoke the ability for you to process credit cards.
All that being said companies like PayPal have a PHP SDK:
https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/library_download_sdks

The most correct way is to use HttpContext.Current.Server.MapPath("~/App_Data");
. This means you can only retrieve the path from a method where the HttpContext
is available. It makes sense: the App_Data directory is a web project folder structure [1].
If you need the path to ~/App_Data from a class where you don't have access to the HttpContext
you can always inject a provider interface using your IoC container:
public interface IAppDataPathProvider
{
string GetAppDataPath();
}
Implement it using your HttpApplication
:
public class AppDataPathProvider : IAppDataPathProvider
{
public string GetAppDataPath()
{
return MyHttpApplication.GetAppDataPath();
}
}
Where MyHttpApplication.GetAppDataPath
looks like:
public class MyHttpApplication : HttpApplication
{
// of course you can fetch&store the value at Application_Start
public static string GetAppDataPath()
{
return HttpContext.Current.Server.MapPath("~/App_Data");
}
}

Thanks loads for the answers above. I'm adding an answer for a specific use-case...
On a project with two target architectures each with its own build configuration (the main target is an embedded AVR platform; the second target is my local Linux PC for running unit tests) I found it necessary to set Preferences -> C/C++ -> Indexer -> Use active build configuration

As I know the way you can do it is to override paintComponent
method that demands to inherit JPanel
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g); // paint the background image and scale it to fill the entire space
g.drawImage(/*....*/);
}
The other way (a bit complicated) to create second custom JPanel
and put is as background for your main
ImagePanel
public class ImagePanel extends JPanel
{
private static final long serialVersionUID = 1L;
private Image image = null;
private int iWidth2;
private int iHeight2;
public ImagePanel(Image image)
{
this.image = image;
this.iWidth2 = image.getWidth(this)/2;
this.iHeight2 = image.getHeight(this)/2;
}
public void paintComponent(Graphics g)
{
super.paintComponent(g);
if (image != null)
{
int x = this.getParent().getWidth()/2 - iWidth2;
int y = this.getParent().getHeight()/2 - iHeight2;
g.drawImage(image,x,y,this);
}
}
}

public class EmptyPanel extends JPanel{
private static final long serialVersionUID = 1L;
public EmptyPanel() {
super();
init();
}
@Override
public boolean isOptimizedDrawingEnabled() {
return false;
}
public void init(){
LayoutManager overlay = new OverlayLayout(this);
this.setLayout(overlay);
ImagePanel iPanel = new ImagePanel(new IconToImage(IconFactory.BG_CENTER).getImage());
iPanel.setLayout(new BorderLayout());
this.add(iPanel);
iPanel.setOpaque(false);
}
}

public class IconToImage {
Icon icon;

public IconToImage(Icon icon) {
this.icon = icon;
image = iconToImage();
}

return ((ImageIcon)icon).getImage();
} else {

I think of Divide & Conquer
as an recursive approach and Dynamic Programming
as table filling.
For example, Merge Sort
is a Divide & Conquer
algorithm, as in each step, you split the array into two halves, recursively call Merge Sort
upon the two halves and then merge them.
Knapsack
is a Dynamic Programming
algorithm as you are filling a table representing optimal solutions to subproblems of the overall knapsack. Each entry in the table corresponds to the maximum value you can carry in a bag of weight w given items 1-j.

Daemon threads are like assistants. Non-Daemon threads are like front performers. Assistants help performers to complete a job. When the job is completed, no help is needed by performers to perform anymore. As no help is needed the assistants leave the place. So when the jobs of Non-Daemon threads is over, Daemon threads march away.

@Html.TextAreaFor(model => model.Text)
After taking a look at the API, you can pass the dialog your activity or getActivity if you're in a fragment, then forcefully clean it up with dialog.dismiss() in the return methods to prevent leaks.
Though it is not explicitly stated anywhere I know, it seems you are passed back the dialog in the OnClickHandlers just to do this.
In this case your while
loop will look like
int i = 0;
int a = 0;
while (i < n){

Yes, you can do this. Assuming your classes exist in the global namespace, something like this will do it:
import types
class Foo:
pass
def str_to_class(s):
if s in globals() and isinstance(globals()[s], types.ClassType):
return globals()[s]
return None
str_to_class('Foo')
==> <class __main__.Foo at 0x340808cc>

Finally if none of these are your issue, it would be helpful to know if you are getting any run-time connect errors.

The solution below uses a double loop to add data to the bottom of a 2x2 array in the Case 3. The inner loop pushes selected elements' values into a new row array. The outerloop then pushes the new row array to the bottom of an existing array (see Newbie: Add values to two-dimensional array with for loops, Google Apps Script).
In this example, I created a function that extracts a section from an existing array. The extracted section can be a row (full or partial), a column (full or partial), or a 2x2 section of the existing array. A new blank array (newArr) is filled by pushing the relevant section from the existing array (arr) into the new array.
function arraySection(arr, r1, c1, rLength, cLength) {
rowMax = arr.length;
if(isNaN(rowMax)){rowMax = 1};
colMax = arr[0].length;
if(isNaN(colMax)){colMax = 1};
var r2 = r1 + rLength - 1;
var c2 = c1 + cLength - 1;
if ((r1< 0 || r1 > r2 || r1 > rowMax || (r1 | 0) != r1) || (r2 < 0 ||
r2 > rowMax || (r2 | 0) != r2)|| (c1< 0 || c1 > c2 || c1 > colMax ||
(c1 | 0) != c1) ||(c2 < 0 || c2 > colMax || (c2 | 0) != c2)){
throw new Error(
'arraySection: invalid input')
return;
};
var newArr = [];
// Case 1: extracted section is a column array,
// all elements are in the same column
if (c1 == c2){
for (var i = r1; i <= r2; i++){
// Logger.log("arr[i][c1] for i = " + i);
// Logger.log(arr[i][c1]);
newArr.push([arr[i][c1]]);
};
};
// Case 2: extracted section is a row array,
// all elements are in the same row
if (r1 == r2 && c1 != c2){
for (var j = c1; j <= c2; j++){
newArr.push(arr[r1][j]);
};
};
// Case 3: extracted section is a 2x2 section
if (r1 != r2 && c1 != c2){
for (var i = r1; i <= r2; i++) {
rowi = [];
for (var j = c1; j <= c2; j++) {
rowi.push(arr[i][j]);
}
newArr.push(rowi)
};
};
return(newArr);
};
As the Jquery replaceWith() code was too bulky, tricky and complicated, here's my own solution. =)
The best way is to use outerHTML property, but it is not crossbrowsered yet, so I did some trick, weird enough, but simple.
Here is the code
var str = '<a href="http://www.com">item to replace</a>'; //it can be anything
var Obj = document.getElementById('TargetObject'); //any element to be fully replaced
if(Obj.outerHTML) { //if outerHTML is supported
Obj.outerHTML=str; ///it's simple replacement of whole element with contents of str var
}
else { //if outerHTML is not supported, there is a weird but crossbrowsered trick
var tmpObj=document.createElement("div");
tmpObj.innerHTML='<!--THIS DATA SHOULD BE REPLACED-->';
ObjParent=Obj.parentNode; //Okey, element should be parented
ObjParent.replaceChild(tmpObj,Obj); //here we placing our temporary data instead of our target, so we can find it then and replace it into whatever we want to replace to
ObjParent.innerHTML=ObjParent.innerHTML.replace('<div><!--THIS DATA SHOULD BE REPLACED--></div>',str);
}
That's all
If you are using kotlin then the context will be already defined in the fragment. So just use that context. Try the following code to show a toast message.
