Edit!: Please be sure that you should have both Python installed on your computer.
Maybe my answer is late for you but I can help someone who has the same problem!
You don't have to download both Anaconda
.
If you are using Spyder
and Jupyter
in Anaconda environmen and,
If you have already Anaconda 2 type in Terminal:
python3 -m pip install ipykernel
python3 -m ipykernel install --user
If you have already Anaconda 3 then type in terminal:
python2 -m pip install ipykernel
python2 -m ipykernel install --user
Then before use Spyder
you can choose Python environment like below!
Sometimes only you can see root and your new Python environment, so root is your first anaconda environment!
Also this is Jupyter. You can choose python version like this!
I hope it will help.
I have had problems with @JodaStephen's implementation on JBoss EAP 6. So, I rewrote the conversion following Oracle's Java Tutorial in http://docs.oracle.com/javase/tutorial/datetime/iso/legacy.html.
Date input = new Date();
GregorianCalendar gregorianCalendar = (GregorianCalendar) Calendar.getInstance();
gregorianCalendar.setTime(input);
ZonedDateTime zonedDateTime = gregorianCalendar.toZonedDateTime();
zonedDateTime.toLocalDate();
It should be put in the HTTP Authorization header. The spec is here https://tools.ietf.org/html/rfc7235
If this is the only application where you're going to use this variable, Felix's approach is excellent. However, if you're writing a jQuery plugin, consider "namespacing" (details on the quotes later...) variables and functions needed under the jQuery object. For example, I'm currently working on a jQuery popup menu that I've called miniMenu. Thus, I've defined a "namespace" miniMenu
under jQuery, and I place everything there.
The reason I use quotes when I talk about JavaScript namespaces is that they aren't really namespaces in the normal sense. Instead, I just use a JavaScript object and place all my functions and variables as properties of this object.
Also, for convenience, I usually sub-space the plugin namespace with an i
namespace for stuff that should only be used internally within the plugin, so as to hide it from users of the plugin.
This is how it works:
// An object to define utility functions and global variables on:
$.miniMenu = new Object();
// An object to define internal stuff for the plugin:
$.miniMenu.i = new Object();
Now I can just do $.miniMenu.i.globalVar = 3
or $.miniMenu.i.parseSomeStuff = function(...) {...}
whenever I need to save something globally, and I still keep it out of the global namespace.
This can be installed via conda with the command conda install -c anaconda python=3.7
as per https://anaconda.org/anaconda/python.
Though not all packages support 3.7 yet, running conda update --all
may resolve some dependency failures.
If your class extends JFrame then use this.setTitle(newTitle.getText());
If not and it contains a JFrame let's say named myFrame, then use myFrame.setTitle(newTitle.getText());
Now that you have posted your program, it is obvious that you need only one JTextField to get the new title. These changes will do the trick:
JTextField poolLengthText, poolWidthText, poolDepthText, poolVolumeText, hotTub,
hotTubLengthText, hotTubWidthText, hotTubDepthText, hotTubVolumeText, temp, results,
newTitle;
and:
public void createOptions()
{
options = new JPanel();
options.setLayout(null);
JLabel labelOptions = new JLabel("Change Company Name:");
labelOptions.setBounds(120, 10, 150, 20);
options.add(labelOptions);
newTitle = new JTextField("Some Title");
newTitle.setBounds(80, 40, 225, 20);
options.add(newTitle);
// myTitle = new JTextField("My Title...");
// myTitle.setBounds(80, 40, 225, 20);
// myTitle.add(labelOptions);
JButton newName = new JButton("Set New Name");
newName.setBounds(60, 80, 150, 20);
newName.addActionListener(this);
options.add(newName);
JButton Exit = new JButton("Exit");
Exit.setBounds(250, 80, 80, 20);
Exit.addActionListener(this);
options.add(Exit);
}
and:
private void New_Name()
{
this.setTitle(newTitle.getText());
}

Execute the following on your terminal to get the latest stable version:
sudo gem install cocoapods
Add --pre
to get the latest pre release:
sudo gem install cocoapods --pre
If you originally installed the cocoapods gem using sudo
, you should use that command again.
Later on, when you're actively using CocoaPods by installing pods, you will be notified when new versions become available with a CocoaPods X.X.X is now available, please update message.
When shifting left, there is no difference between arithmetic and logical shift. When shifting right, the type of shift depends on the type of the value being shifted.
(As background for those readers unfamiliar with the difference, a "logical" right shift by 1 bit shifts all the bits to the right and fills in the leftmost bit with a 0. An "arithmetic" shift leaves the original value in the leftmost bit. The difference becomes important when dealing with negative numbers.)
When shifting an unsigned value, the >> operator in C is a logical shift. When shifting a signed value, the >> operator is an arithmetic shift.
For example, assuming a 32 bit machine:
signed int x1 = 5;
assert((x1 >> 1) == 2);
signed int x2 = -5;
assert((x2 >> 1) == -3);
unsigned int x3 = (unsigned int)-5;
assert((x3 >> 1) == 0x7FFFFFFD);
Try this:
Integer startIn = null;
try {
startIn = Integer.valueOf(startField.getText());
} catch (NumberFormatException e) {
.
.
.
}
if (startIn == null) {
// Prompt for value...
}
You have to do binding in a directive. Look at this:
angular.module('ng', []).
directive('sliderRange', function($parse, $timeout){
return {
restrict: 'A',
replace: true,
transclude: false,
compile: function(element, attrs) {
var html = '<div class="slider-range"></div>';
var slider = $(html);
element.replaceWith(slider);
var getterLeft = $parse(attrs.ngModelLeft), setterLeft = getterLeft.assign;
var getterRight = $parse(attrs.ngModelRight), setterRight = getterRight.assign;
return function (scope, slider, attrs, controller) {
var vsLeft = getterLeft(scope), vsRight = getterRight(scope), f = vsLeft || 0, t = vsRight || 10;
var processChange = function() {
var vs = slider.slider("values"), f = vs[0], t = vs[1];
setterLeft(scope, f);
setterRight(scope, t);
}
slider.slider({
range: true,
min: 0,
max: 10,
step: 1,
change: function() { setTimeout(function () { scope.$apply(processChange); }, 1) }
}).slider("values", [f, t]);
};
}
};
});
This shows you an example of a slider range, done with jQuery UI. Example usage:
<div slider-range ng-model-left="question.properties.range_from" ng-model-right="question.properties.range_to"></div>
The whole point of a workspace is to group a set of related projects together that usually make up an application. The workspace framework comes down to the eclipse.core.resources
plugin and it naturally by design makes sense.
Projects have natures, builders are attached to specific projects and as you change resources in one project you can see in real time compile or other issues in projects that are in the same workspace. So the strategy I suggest is have different workspaces for different projects you work on but without a workspace in eclipse there would be no concept of a collection of projects and configurations and after all it's an IDE tool.
If that does not make sense ask how Net Beans or Visual Studio addresses this? It's the same theme. Maven is a good example, checking out a group of related maven projects into a workspace lets you develop and see errors in real time. If not a workspace what else would you suggest? An RCP application can be a different beast depending on what its used for but in the true IDE sense I don't know what would be a better solution than a workspace or context of projects. Just my thoughts. - Duncan

I don't see much details about performance and optimizer in the other answers.
Sometimes it is good to know that only INNER JOIN
is associative which means the optimizer has the most option to play with it. It can reorder the join order to make it faster keeping the same result. The optimizer can use the most join modes.
Generally it is a good practice to try to use INNER JOIN
instead of the different kind of joins. (Of course if it is possible considering the expected result set.)
There are a couple of good examples and explanation here about this strange associative behavior:
select * from table where
(dtColumn between #3/1/2009# and #3/31/2009#) and
(hour(dtColumn) between 6 and 22) and
(weekday(dtColumn, 1) between 2 and 4)
Just small change need in test.ts
file inside src folder:
const context = require.context('./', true, /test-example\.spec\.ts$/);
Here, test-example
is the exact file name which we need to run
In the same way, if you need to test the service file only you can replace the filename like "/test-example.service"
My reputation being too small to comment an answer, here is my feedback concerning roquen answer (using settings on xmlwriter to force the stream to close): it works perfectly and it made me save a lot of time. roquen's example requires some adjustment, here is the code that works on .NET framework 4.8 :
XmlWriterSettings settings = new XmlWriterSettings();
settings.CloseOutput = true;
writer = XmlWriter.Create(stream, settings);
You must use an integer value for the CURLOPT_SSLVERSION
value, not a string as listed above
Try this:
curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 6); //Integer NOT string TLS v1.2
http://php.net/manual/en/function.curl-setopt.php
value should be an integer for the following values of the option parameter:
CURLOPT_SSLVERSION
One of
CURL_SSLVERSION_DEFAULT (0)
CURL_SSLVERSION_TLSv1 (1)
CURL_SSLVERSION_SSLv2 (2)
CURL_SSLVERSION_SSLv3 (3)
CURL_SSLVERSION_TLSv1_0 (4)
CURL_SSLVERSION_TLSv1_1 (5)
CURL_SSLVERSION_TLSv1_2 (6).

Since Spring 3.1 the id
attribute is an xsd:string
and permits the same range of characters as the name
attribute.
The only difference between an id
and a name
is that a name
can contain multiple aliases separated by a comma, semicolon or whitespace, whereas an id
must be a single value.
From the Spring 3.2 documentation:
In XML-based configuration metadata, you use the id and/or name attributes to specify the bean identifier(s). The id attribute allows you to specify exactly one id. Conventionally these names are alphanumeric ('myBean', 'fooService', etc), but may special characters as well. If you want to introduce other aliases to the bean, you can also specify them in the name attribute, separated by a comma (,), semicolon (;), or white space. As a historical note, in versions prior to Spring 3.1, the id attribute was typed as an xsd:ID, which constrained possible characters. As of 3.1, it is now xsd:string. Note that bean id uniqueness is still enforced by the container, though no longer by XML parsers.
To read binary ASCII characters with great speed using only your head:
Letters start with leading bits 01. Bit 3 is on (1) for lower case, off (0) for capitals. Scan the following bits 4–8 for the first that is on, and select the starting letter from the same index in this string: “PHDBA” (think P.H.D., Bachelors in Arts). E.g. 1xxxx = P, 01xxx = H, etc. Then convert the remaining bits to an integer value (e.g. 010 = 2), and count that many letters up from your starting letter. E.g. 01001010 => H+2 = J.

None of these things worked for me. I'm trying to access native code through the jni, first with NDK samples. What I found was the build won't run if jarlist.cache is not present in the project bin directory. If I copy one from another project to that location (may need to refresh to see the folder in Eclipse), build works every time.
Please try with this
$pattern = "/My name is '\(.*\)' and im fine/";
Using parse_str()
.
$str = 'pg_id=2&parent_id=2&document&video';
parse_str($str, $arr);
print_r($arr);
To add to the above, the most obvious place to add stylesheet_link_tag is in your global application layout - application.html.erb.
XmlNodes come with an OwnerDocument property.
Perhaps you can just do:
//Node is an XmlNode pulled from an XmlDocument
XmlElement e = node.OwnerDocument.CreateElement("MyNewElement");
e.InnerText = "Some value";
node.AppendChild(e);
Here's how I do it:
Code:
let fs = require('fs');
let path = require('path');
let myController = (req, res) => {
let filename = 'myFile.ext';
let absPath = path.join(__dirname, '/my_files/', filename);
let relPath = path.join('./my_files', filename); // path relative to server root
fs.writeFile(relPath, 'File content', (err) => {
if (err) {
console.log(err);
}
res.download(absPath, (err) => {
if (err) {
console.log(err);
}
fs.unlink(relPath, (err) => {
if (err) {
console.log(err);
}
console.log('FILE [' + filename + '] REMOVED!');
});
});
});
};
You could theoretically do the entire thing as simply:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace consoleHelloWorld {
class Program {
static void Main(string[] args) {
Console.WriteLine(DateTime.Now.ToString("MM.dd.yyyy"));
}
}
}
This one works like a charm!

I had a problem with an element which had to be colored RED on hover and be BLUE on click while being hovered. To achieve this with css you need for example:
h1:hover { color: red; }
h1:active { color: blue; }
<h1>This is a heading.</h1>
I struggled for some time until I discovered that the order of CSS selectors was the problem I was having. The problem was that I switched the places and the active selector was not working. Then I found out that :hover
to go first and then :active
.
I am using C# mvc Application. I have created a session in the Controller class like this
string description = accessDB.LookupSomeString(key, ImpDate);
this.Session["description"] = description;
in the View, We access the session value and store it in a variable, like this (this is within an $.ajax, but I think it should work within any jquery)
var Sessiondescription = '@Session["description"]';
alert(Sessiondescription);
Once you have done your processing in the selectFunction() you could do the following
document.getElementById('select').selectedIndex = 0;
document.getElementById('select').value = 'Default';
You should bring your data into long (i.e. molten) format to use it with ggplot2
:
library("reshape2")
mdf <- melt(mdf, id.vars="Company", value.name="value", variable.name="Year")
And then you have to use aes( ... , group = Company )
to group them:
ggplot(data=mdf, aes(x=Year, y=value, group = Company, colour = Company)) +
geom_line() +
geom_point( size=4, shape=21, fill="white")

I have had this issue too, tried a lot. Used SDK as well as Visual Studio signing, but everywhere I got "No certificates were found that met all the given criteria".
Solution: Be aware that, if "after private key filter": '0 left' shows up with option signtool sign /debug..., the cause is your PC doesn't has the CA itself in the store. To solve this, install the CA first (in my case a .crt file), then run the sign again. It should work right now!
Signtool only can be used with a CA which is requested ánd owned by the same PC.
Adding some content to a div, whether through jQuery or via de DOM-API directly, defaults to the .appendChild()
function. What you can do is to override the .appendChild()
function of the current object and implement an observer in it. Now having overridden our .appendChild()
function, we need to borrow that function from an other object to be able to append the content. Therefor we call the .appendChild()
of an other div to finally append the content. Ofcourse, this counts also for the .removeChild()
.
var obj = document.getElementById("mydiv");
obj.appendChild = function(node) {
alert("changed!");
// call the .appendChild() function of some other div
// and pass the current (this) to let the function affect it.
document.createElement("div").appendChild.call(this, node);
}
};
Here you can find a naïf example. You can extend it by yourself I guess. http://jsfiddle.net/RKLmA/31/
By the way: this shows JavaScript complies the OpenClosed priciple. :)
Are Composition and Inheritance the same?
They are not same.
Composition : It enables a group of objects have to be treated in the same way as a single instance of an object. The intent of a composite is to "compose" objects into tree structures to represent part-whole hierarchies
Inheritance: A class inherits fields and methods from all its superclasses, whether direct or indirect. A subclass can override methods that it inherits, or it can hide fields or methods that it inherits.
If I want to implement the composition pattern, how can I do that in Java?
Wikipedia article is good enough to implement composite pattern in java.

As you can see the evolution is insane, about 560 time faster than reported in 2012.
On my machines and servers, following my numerous experiments, basics for loops are the fastest. This is even clearer using nested loops ($i $j $k..)
It is also the most flexible in usage, and has a better readability from my view.
In regards to veggerby's solution, if you are trying to implement it on a VB app, be careful trying to run the supplied code through a translator. The following will work:
Imports System.Web
Imports System.Web.Services
Imports System.Web.SessionState
Public Class SessionHeartbeatHttpHandler
Implements IHttpHandler
Implements IRequiresSessionState
ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
Get
Return False
End Get
End Property
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
context.Session("Heartbeat") = DateTime.Now
End Sub
End Class
Also, instead of calling like heartbeat() function like:
setTimeout("heartbeat()", 300000);
Instead, call it like:
setInterval(function () { heartbeat(); }, 300000);
Number one, setTimeout only fires once whereas setInterval will fire repeatedly. Number two, calling heartbeat() like a string didn't work for me, whereas calling it like an actual function did.
And I can absolutely 100% confirm that this solution will overcome GoDaddy's ridiculous decision to force a 5 minute apppool session in Plesk!
For unsigned long you can use UnsignedLong class from Guava library:
It supports various operations:
The thing that seems missing at the moment are byte shift operators. If you need those you can use BigInteger from Java.
You could concatenate the location protocol and the host:
var root = location.protocol + '//' + location.host;
For a url, let say 'http://stackoverflow.com/questions'
, it will return 'http://stackoverflow.com'
I ran across this article in the results returned by a search related to the IF command in a batch file, and I couldn't resist the opportunity to correct the misconception that IF blocks are limited to single commands. Following is a portion of a production Windows NT command script that runs daily on the machine on which I am composing this reply.
if "%COPYTOOL%" equ "R" (
WWLOGGER.exe "%APPDATA%\WizardWrx\%~n0.LOG" "Using RoboCopy to make a backup of %USERPROFILE%\My Documents\Outlook Files\*"
%TOOLPATH% %SRCEPATH% %DESTPATH% /copyall %RCLOGSTR% /m /np /r:0 /tee
C:\BIN\ExitCodeMapper.exe C:\BIN\ExitCodeMapper.INI[Robocopy] %TEMP%\%~n0.TMP %ERRORLEVEL%
) else (
WWLOGGER.exe "%APPDATA%\WizardWrx\%~n0.LOG" "Using XCopy to make a backup of %USERPROFILE%\My Documents\Outlook Files\*"
call %TOOLPATH% "%USERPROFILE%\My Documents\Outlook Files\*" "%USERPROFILE%\My Documents\Outlook Files\_backups" /f /m /v /y
C:\BIN\ExitCodeMapper.exe C:\BIN\ExitCodeMapper.INI[Xcopy] %TEMP%\%~n0.TMP %ERRORLEVEL%
)
Perhaps blocks of two or more lines applies exclusively to Windows NT command scripts (.CMD files), because a search of the production scripts directory of an application that is restricted to old school batch (.BAT) files, revealed only one-command blocks. Since the application has gone into extended maintenance (meaning that I am not actively involved in supporting it), I can't say whether that is because I didn't need more than one line, or that I couldn't make them work.
Regardless, if the latter is true, there is a simple workaround; move the multiple lines into either a separate batch file or a batch file subroutine. I know that the latter works in both kinds of scripts.
The documentation has been updated. My answer has substantial changes vs the accepted answer: I wanted to reflect documentation is up-to-date, and accepted answer has a few broken links.
Also, I didn't understand when the accepted answer said "it defaults to node server.js
". I think the documentation clarifies the default behavior:
npm-start
Start a package
Synopsis
npm start [-- <args>]
Description
This runs an arbitrary command specified in the package's "
start
" property of its "scripts
" object. If no "start
" property is specified on the "scripts
" object, it will runnode server.js
.
In summary, running npm start
could do one of two things:
npm start {command_name}
: Run an arbitrary command (i.e. if such command is specified in the start
property of package.json's scripts
object)npm start
: Else if no start
property exists (or no command_name
is passed): Run node server.js
, (which may not be appropriate, for example the OP doesn't have server.js
; the OP runs node
app.js
)package.json
in the directory where you run npm start
, you may see an error: npm ERR! enoent ENOENT: no such file or directory, open '.\package.json'
The @Transactional
annotation takes a timeout parameter where you can specify timeout in seconds for a specific method in the @RestController
@RequestMapping(value = "/method",
method = RequestMethod.POST,
produces = MediaType.APPLICATION_JSON_VALUE)
@Timed
@Transactional(timeout = 120)
string userName;
string userId;
if (HttpContext.Current != null && HttpContext.Current.User != null
&& HttpContext.Current.User.Identity.Name != null)
{
userName = HttpContext.Current.User.Identity.Name;
userId = HttpContext.Current.User.Identity.GetUserId();
}
Or based on Darrel Miller's comment, maybe use this to retrieve the HttpContext first.
// get httpContext
object httpContext;
actionContext.Request.Properties.TryGetValue("MS_HttpContext", out httpContext);
See also:
parent.children
is not an array. It is HTMLCollection and it does not have forEach
method. You can convert it to the array first. For example in ES6:
Array.from(parent.children).forEach(child => {
console.log(child)
});
or using spread operator:
[...parent.children].forEach(function (child) {
console.log(child)
});
With a simple JSON object, you don't need jQuery:
for (var i in json) {
for (var j in json[i]) {
console.log(json[i][j]);
}
}
If Ubuntu Docker image isn't recognizing 'ifconfig' inside of GNS3, you'll need to open Ubuntu docker image on your host.
Assuming you already have docker on your host pc and ubuntu pull'd from docker images. Enter these commands in your host OS (Linux, CentOS, etc.) CLI.
$docker images
$docker run -it ubuntu
$apt-get update
$apt-get install net-tools
(side note: you can add whatever other tools and services that you would like to add now, but for now this is just to get ifconfig to work.)
$exit
Now you will commit these changes to Docker. This link for committing changes is the best summary and works (skip to Step 4):
https://phoenixnap.com/kb/how-to-commit-changes-to-docker-image#htoc-step-3-modify-the-container
When you re-open the docker image in GNS3 you should now have the ifconfig command usable and whatever other tools or services you added to the container.
Enjoy!
Your tables should have as immediate children just tbody
and thead
elements, with the rows within*. So, amend the HTML to be:
<table border="1" width="100%" id="test">
<tbody>
<tr>
<td>
<table border="1" width="100%">
<tbody>
<tr>
<td>table 2</td>
</tr>
</tbody>
</table>
</td>
</tr>
<tr><td>table 1</td></tr>
<tr><td>table 1</td></tr>
<tr><td>table 1</td></tr>
</tbody>
</table>
Then amend your selector slightly to this:
#test > tbody > tr:last-child { background:#ff0000; }
See it in action here. That makes use of the child selector, which:
...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.
So, you are targeting only direct children of tbody
elements that are themselves direct children of your #test
table.
The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:
#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }
* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:
...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.
I found a good article about using the WMP with Firefox on MSDN.
Based on MSDN's article and after doing some trials and errors, I found using JavaScript is better than using conditional comments or nested "EMBED/OBJECT" tags.
I made a JS function that generate WMP object based on given arguments:
<script type="text/javascript">
function generateWindowsMediaPlayer(
holderId, // String
height, // Number
width, // Number
videoUrl // String
// you can declare more arguments for more flexibility
) {
var holder = document.getElementById(holderId);
var player = '<object ';
player += 'height="' + height.toString() + '" ';
player += 'width="' + width.toString() + '" ';
videoUrl = encodeURI(videoUrl); // Encode for special characters
if (navigator.userAgent.indexOf("MSIE") < 0) {
// Chrome, Firefox, Opera, Safari
//player += 'type="application/x-ms-wmp" '; //Old Edition
player += 'type="video/x-ms-wmp" '; //New Edition, suggested by MNRSullivan (Read Comments)
player += 'data="' + videoUrl + '" >';
}
else {
// Internet Explorer
player += 'classid="clsid:6BF52A52-394A-11d3-B153-00C04F79FAA6" >';
player += '<param name="url" value="' + videoUrl + '" />';
}
player += '<param name="autoStart" value="false" />';
player += '<param name="playCount" value="1" />';
player += '</object>';
holder.innerHTML = player;
}
</script>
Then I used that function by writing some markups and inline JS like these:
<div id='wmpHolder'></div>
<script type="text/javascript">
window.addEventListener('load', generateWindowsMediaPlayer('wmpHolder', 240, 320, 'http://mysite.com/path/video.ext'));
</script>
You can use jQuery.ready instead of window load event to making the codes more backward-compatible and cross-browser.
I tested the codes over IE 9-10, Chrome 27, Firefox 21, Opera 12 and Safari 5, on Windows 7/8.
The following will only work if you do not have spaces in your input:
xargs -L 1
xargs --max-lines=1 # synonym for the -L option
from the man page:
-L max-lines
Use at most max-lines nonblank input lines per command line.
Trailing blanks cause an input line to be logically continued on
the next input line. Implies -x.
This works as well:
select * from mde_product where cfn = 'A3D"&"R01'
you define &
as literal by enclosing is with double qoutes "&"
in the string.
"Both" has been stated above, and is the obvious answer...but IMO, white box testing goes far beyond developer unit testing (althoughI suppose it could depend on where you draw the line between white and black). For example, code coverage analysis is a common white box approach - i.e. run some scenarios or tests, and examine the results looking for holes in testing. Even if unit tests have 100% cc, measuring cc on common user scenarios can reveal code that may potentially need even more testing.
Another place where white box testing helps is examining data types, constants and other information to look for boundaries, special values, etc. For example, if an application has an input that takes a numeric input, a bb only approach could require the tester to "guess" at what values would be good for testing, whereas a wb approach may reveal that all values between 1-256 are treated one way, while larger values are treated another way...and perhaps the number 42 has yet another code path.
So, to answer the original question - both bb and wb are essential for good testing.
Fiddle: http://jsfiddle.net/simple/BdQvp/
You can do it like so:
I have added two buttons in the Fiddle to illustrate how you can insert or clear values in those input fields through buttons. You just capture the onClick event and call the function.
//Fires when the Document Loads, clears all input fields
$(document).ready(function() {
$('.fetch_results').find('input:text').val('');
});
//Custom Functions that you can call
function resetAllValues() {
$('.fetch_results').find('input:text').val('');
}
function addSomeValues() {
$('.fetch_results').find('input:text').val('Lala.');
}
Update:
Check out this great answer below by Beena as well for a more universal approach.
I know this question is old, but I came across it in my search for the answer to my similar question. I thought I would share the very useful tip that I have been given.
When converting to int, simply add .5
to your value before downcasting. As downcasting to int
always drops to the lower number (e.g. (int)1.7 == 1
), if your number is .5
or higher, adding .5
will bring it up into the next number and your downcast to int
should return the correct value. (e.g. (int)(1.8 + .5) == 2
)
Or you can execute in python console or in Jupyter Notebook:
import csv
data = open("file.csv","r")
data
You will see information about the data object like this:
<_io.TextIOWrapper name='arch.csv' mode='r' encoding='cp1250'>
As you can see it contains encoding infotmation.
Try git diff --ignore-space-at-eol
, or git diff --ignore-space-change
, or git diff --ignore-all-space
.
You'll need to use UNION
to combine the results of two queries. In your case:
SELECT ChargeNum, CategoryID, SUM(Hours)
FROM KnownHours
GROUP BY ChargeNum, CategoryID
UNION ALL
SELECT ChargeNum, 'Unknown' AS CategoryID, SUM(Hours)
FROM UnknownHours
GROUP BY ChargeNum
Note - If you use UNION ALL
as in above, it's no slower than running the two queries separately as it does no duplicate-checking.
Applying the full_extent()
function in an answer by @Joe 3 years later from here, you can get exactly what the OP was looking for. Alternatively, you can use Axes.get_tightbbox()
which gives a little tighter bounding box
import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np
from matplotlib.transforms import Bbox
def full_extent(ax, pad=0.0):
"""Get the full extent of an axes, including axes labels, tick labels, and
titles."""
# For text objects, we need to draw the figure first, otherwise the extents
# are undefined.
ax.figure.canvas.draw()
items = ax.get_xticklabels() + ax.get_yticklabels()
# items += [ax, ax.title, ax.xaxis.label, ax.yaxis.label]
items += [ax, ax.title]
bbox = Bbox.union([item.get_window_extent() for item in items])
return bbox.expanded(1.0 + pad, 1.0 + pad)
# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')
ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')
# Save the full figure...
fig.savefig('full_figure.png')
# Save just the portion _inside_ the second axis's boundaries
extent = full_extent(ax2).transformed(fig.dpi_scale_trans.inverted())
# Alternatively,
# extent = ax.get_tightbbox(fig.canvas.renderer).transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)
I'd post a pic but I lack the reputation points
You can delete files in PHP using the unlink()
function.
unlink('path/to/file.jpg');
This is what SSMS uses when you script using the DROP and CREATE
option
IF EXISTS (SELECT *
FROM sys.objects
WHERE object_id = OBJECT_ID(N'[dbo].[foo]')
AND type IN ( N'FN', N'IF', N'TF', N'FS', N'FT' ))
DROP FUNCTION [dbo].[foo]
GO
This approach to deploying changes means that you need to recreate all permissions on the object so you might consider ALTER
-ing if Exists instead.
document.getElementById('id1').bgColor = '#00FF00';
seems to work. I don't think .style.backgroundColor
does.
This answer taught me that you can set headers for an entire session:
s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})
# both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})
You are facing this problem because when you are posting your forms so after reloading your dropdown is unable to find data in viewbag. So make sure that code you are using in get method while retrieving your data from db or from static list, copy paste that code into post verb as well..
Happy Coding :)
As eaon21 and monkey said, source map files basically turn minified code into its unminified version for debugging.
You can find the .map files here. Just add them into the same directory as the minified js files and it'll stop complaining. The reason they get fetched is the
/*
//@ sourceMappingURL=angular.min.js.map
*/
at the end of angular.min.js. If you don't want to add the .map files you can remove those lines and it'll stop the fetch attempt, but if you plan on debugging it's always good to keep the source maps linked.
The HttpWebRequest modifies the CookieContainer assigned to it. There is no need to process returned cookies. Simply assign your cookie container to every web request.
public class CookieAwareWebClient : WebClient
{
public CookieContainer CookieContainer { get; set; } = new CookieContainer();
protected override WebRequest GetWebRequest(Uri uri)
{
WebRequest request = base.GetWebRequest(uri);
if (request is HttpWebRequest)
{
(request as HttpWebRequest).CookieContainer = CookieContainer;
}
return request;
}
}
It appears you no longer need toggleButton.setTextOff(textOff); and toggleButton.setTextOn(textOn);. The text for each toggled state will change by merely including the relevant xml characteristics. This will override the default ON/OFF text.
<ToggleButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/toggleText"
android:textOff="ADD TEXT"
android:textOn="CLOSE TEXT"
android:layout_centerHorizontal="true"
android:layout_marginTop="10dp"
android:visibility="gone"/>
Adding to the solutions of others, I'd like to suggest using the plotly
package for R
, as this has worked well for me.
Below, I'm using the reformatted dataset suggested above, from xyz-tripplets to axis vectors x and y and a matrix z:
x <- 1:5/10
y <- 1:5
z <- x %o% y
z <- z + .2*z*runif(25) - .1*z
library(plotly)
plot_ly(x=x,y=y,z=z, type="surface")
The rendered surface can be rotated and scaled using the mouse. This works fairly well in RStudio.
You can also try it with the built-in volcano
dataset from R
:
plot_ly(z=volcano, type="surface")
The following has worked for me very well:
$("#button").attr('disabled', 'disabled');
If you need a general purpose conversion from a string which per se is not a bool, you should better write a routine similar to the one depicted below. In keeping with the spirit of duck typing, I have not silently passed the error but converted it as appropriate for the current scenario.
>>> def str2bool(st):
try:
return ['false', 'true'].index(st.lower())
except (ValueError, AttributeError):
raise ValueError('no Valid Conversion Possible')
>>> str2bool('garbaze')
Traceback (most recent call last):
File "<pyshell#106>", line 1, in <module>
str2bool('garbaze')
File "<pyshell#105>", line 5, in str2bool
raise TypeError('no Valid COnversion Possible')
TypeError: no Valid Conversion Possible
>>> str2bool('false')
0
>>> str2bool('True')

You are not adding the object to the session, instead you are adding it to the request.
What you need is:
HttpSession session = request.getSession();
session.setAttribute("MySessionVariable", param);
In Servlets you have 4 scopes where you can store data.
Make sure you understand these. For more look here
static
classes are not for anything that needs state. It is useful for putting a bunch of functions together i.e Math
(or Utils
in projects). So the class name just gives us a clue where we can find the functions and nothing more.
Singleton
is my favorite pattern and I use it to manage something at a single point. It's more flexible than static
classes and can maintain it's state. It can implement interfaces, inherit from other classes and allow inheritance.
My rule for choosing between static
and singleton
:
If there is a bunch of functions that should be kept together, then static
is the choice.
Anything else which needs single access to some resources, could be implemented as a singleton
.
If I move
CreateUser.py
to the main user_management directory, I can easily use:import Modules.LDAPManager
to importLDAPManager.py
--- this works.
Please, don't. In this way the LDAPManager
module used by CreateUser
will not be the same as the one imported via other imports. This can create problems when you have some global state in the module or during pickling/unpickling. Avoid imports that work only because the module happens to be in the same directory.
When you have a package structure you should either:
Use relative imports, i.e if the CreateUser.py
is in Scripts/
:
from ..Modules import LDAPManager
Note that this was (note the past tense) discouraged by PEP 8 only because old versions of python didn't support them very well, but this problem was solved years ago. The current version of PEP 8 does suggest them as an acceptable alternative to absolute imports. I actually like them inside packages.
Use absolute imports using the whole package name(CreateUser.py
in Scripts/
):
from user_management.Modules import LDAPManager
In order for the second one to work the package user_management
should be installed inside the PYTHONPATH
. During development you can configure the IDE so that this happens, without having to manually add calls to sys.path.append
anywhere.
Also I find it odd that Scripts/
is a subpackage. Because in a real installation the user_management
module would be installed under the site-packages
found in the lib/
directory (whichever directory is used to install libraries in your OS), while the scripts should be installed under a bin/
directory (whichever contains executables for your OS).
In fact I believe Script/
shouldn't even be under user_management
. It should be at the same level of user_management
.
In this way you do not have to use -m
, but you simply have to make sure the package can be found (this again is a matter of configuring the IDE, installing the package correctly or using PYTHONPATH=. python Scripts/CreateUser.py
to launch the scripts with the correct path).
In summary, the hierarchy I would use is:
user_management (package)
|
|------- __init__.py
|
|------- Modules/
| |
| |----- __init__.py
| |----- LDAPManager.py
| |----- PasswordManager.py
|
Scripts/ (*not* a package)
|
|----- CreateUser.py
|----- FindUser.py
Then the code of CreateUser.py
and FindUser.py
should use absolute imports to import the modules:
from user_management.Modules import LDAPManager
During installation you make sure that user_management
ends up somewhere in the PYTHONPATH
, and the scripts inside the directory for executables so that they are able to find the modules. During development you either rely on IDE configuration, or you launch CreateUser.py
adding the Scripts/
parent directory to the PYTHONPATH
(I mean the directory that contains both user_management
and Scripts
):
PYTHONPATH=/the/parent/directory python Scripts/CreateUser.py
Or you can modify the PYTHONPATH
globally so that you don't have to specify this each time. On unix OSes (linux, Mac OS X etc.) you can modify one of the shell scripts to define the PYTHONPATH
external variable, on Windows you have to change the environmental variables settings.
Addendum I believe, if you are using python2, it's better to make sure to avoid implicit relative imports by putting:
from __future__ import absolute_import
at the top of your modules. In this way import X
always means to import the toplevel module X
and will never try to import the X.py
file that's in the same directory (if that directory isn't in the PYTHONPATH
). In this way the only way to do a relative import is to use the explicit syntax (the from . import X
), which is better (explicit is better than implicit).
This will make sure you never happen to use the "bogus" implicit relative imports, since these would raise an ImportError
clearly signalling that something is wrong. Otherwise you could use a module that's not what you think it is.
On Windows I use Far Manager for file search. BSD licensed, works in console, saves time on typing cmdline parameters. Here is its search dialog invoked by Alt-F7.
Using new api fetch:
const dataToSend = JSON.stringify({"email": "[email protected]", "password": "101010"});
let dataReceived = "";
fetch("", {
credentials: "same-origin",
mode: "same-origin",
method: "post",
headers: { "Content-Type": "application/json" },
body: dataToSend
})
.then(resp => {
if (resp.status === 200) {
return resp.json()
} else {
console.log("Status: " + resp.status)
return Promise.reject("server")
}
})
.then(dataJson => {
dataReceived = JSON.parse(dataJson)
})
.catch(err => {
if (err === "server") return
console.log(err)
})
console.log(`Received: ${dataReceived}`)
_x000D_
I face Similar problem now I understand we have some more option : varStatus="loop", Here will be loop will variable which will hold the index of lop.
It can use for use to read for Zeor base index or 1 one base index.
${loop.count}` it will give 1 starting base index.
${loop.index} it will give 0 base index as normal Index of array
start from 0.
For Example :
<c:forEach var="currentImage" items="${cityBannerImages}" varStatus="loop">
<picture>
<source srcset="${currentImage}" media="(min-width: 1000px)"></source>
<source srcset="${cityMobileImages[loop.count]}" media="(min-width:600px)"></source>
<img srcset="${cityMobileImages[loop.count]}" alt=""></img>
</picture>
</c:forEach>

Triggers cannot modify the changed data (Inserted
or Deleted
) otherwise you could get infinite recursion as the changes invoked the trigger again. One option would be for the trigger to roll back the transaction.
Edit: The reason for this is that the standard for SQL is that inserted and deleted rows cannot be modified by the trigger. The underlying reason for is that the modifications could cause infinite recursion. In the general case, this evaluation could involve multiple triggers in a mutually recursive cascade. Having a system intelligently decide whether to allow such updates is computationally intractable, essentially a variation on the halting problem.
The accepted solution to this is not to permit the trigger to alter the changing data, although it can roll back the transaction.
create table Foo (
FooID int
,SomeField varchar (10)
)
go
create trigger FooInsert
on Foo after insert as
begin
delete inserted
where isnumeric (SomeField) = 1
end
go
Msg 286, Level 16, State 1, Procedure FooInsert, Line 5
The logical tables INSERTED and DELETED cannot be updated.
Something like this will roll back the transaction.
create table Foo (
FooID int
,SomeField varchar (10)
)
go
create trigger FooInsert
on Foo for insert as
if exists (
select 1
from inserted
where isnumeric (SomeField) = 1) begin
rollback transaction
end
go
insert Foo values (1, '1')
Msg 3609, Level 16, State 1, Line 1
The transaction ended in the trigger. The batch has been aborted.
plot
has a plot.function
method
plot(eq, 1, 1000)
Or
curve(eq, 1, 1000)
You can force bundler to use the gems you deploy using "bundle package" and "bundle install --local"
On your development machine:
bundle install
(Installs required gems and makes Gemfile.lock)
bundle package
(Caches the gems in vendor/cache)
On the server:
bundle install --local
(--local means "use the gems from vendor/cache")
According to the documentation, just like with any css selector, you can specify as many conditions as you want, and they are treated as logical 'OR'.
This example returns a list of all div elements within the document with a class of either "note" or "alert":
var matches = document.querySelectorAll("div.note, div.alert");
source: https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelectorAll
Meanwhile to get the 'AND' functionality you can for example simply use a multiattribute selector, as jquery says:

ex. "input[id][name$='man']"
specifies both id and name of the element and both conditions must be met. For classes it's as obvious as ".class1.class2
" to require object of 2 classes.
All possible combinations of both are valid, so you can easily get equivalent of more sophisticated 'OR' and 'AND' expressions.
Sorting html table column on page load
var table = $('table#all_items_table');
var rows = table.find('tr:gt(0)').toArray().sort(comparer(3));
for (var i = 0; i < rows.length; i++) {
table.append(rows[i])
}
function comparer(index) {
return function (a, b) {
var v1= getCellValue(a, index),
v2= getCellValue(b, index);
return $.isNumeric(v2) && $.isNumeric(v1) ? v2 - v1: v2.localeCompare(v1)
}
}
function getCellValue(row, index) {
return parseFloat($(row).children('td').eq(index).html().replace(/,/g,'')); //1234234.45645->1234234
}
I have done something like what you're asking just by using jQuery to find the element (such as document.getElementById(...)
) and using the .focus()
call.
To check if a character is lower case, use the islower
method of str
. This simple imperative program prints all the lowercase letters in your string:
for c in s:
if c.islower():
print c
Note that in Python 3 you should use print(c)
instead of print c
.
Possibly ending up with assigning those letters to a different variable.
To do this I would suggest using a list comprehension, though you may not have covered this yet in your course:
>>> s = 'abCd'
>>> lowercase_letters = [c for c in s if c.islower()]
>>> print lowercase_letters
['a', 'b', 'd']
Or to get a string you can use ''.join
with a generator:
>>> lowercase_letters = ''.join(c for c in s if c.islower())
>>> print lowercase_letters
'abd'
Just to be different :)
list($whole, $decimal) = sscanf(1.5, '%d.%d');
As an added benefit, it will only split where both sides consist of digits.
Most of the time you can just npm update (or yarn upgrade) a module to get the latest non breaking changes (respecting the semver specified in your package.json) (<-- read that last part again).
npm update browser-sync
-------
yarn upgrade browser-sync
- Use
npm|yarn outdated
to see which modules have newer versions- Use
npm update|yarn upgrade
(without a package name) to update all modules- Include
--save-dev|--dev
if you want to save the newer version numbers to your package.json. (NOTE: as of npm v5.0 this is only necessary fordevDependencies
).
Major version upgrades:
In your case, it looks like you want the next major version (v2.x.x), which is likely to have breaking changes and you will need to update your app to accommodate those changes. You can install/save the latest 2.x.x
by doing:
npm install browser-sync@2 --save-dev
-------
yarn add browser-sync@2 --dev
...or the latest 2.1.x
by doing:
npm install [email protected] --save-dev
-------
yarn add [email protected] --dev
...or the latest and greatest by doing:
npm install browser-sync@latest --save-dev
-------
yarn add browser-sync@latest --dev
Note: the last one is no different than doing this:
npm uninstall browser-sync --save-dev npm install browser-sync --save-dev ------- yarn remove browser-sync --dev yarn add browser-sync --dev
The
--save-dev
part is important. This will uninstall it, remove the value from your package.json, and then reinstall the latest version and save the new value to your package.json.
You can get all the contact all those which have no number and all those which have no name from this piece of code
public void readContacts() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY + " ASC");
ContactCount = cur.getCount();
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String phone = null;
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
System.out.println("name : " + name + ", ID : " + id);
// get the phone number
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
phone = pCur.getString(
pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
System.out.println("phone" + phone);
}
pCur.close();
}
if (phone == "" || name == "" || name.equals(phone)) {
if (phone.equals(""))
getAllContact.add(new MissingPhoneModelClass("No Number", name, id));
if (name.equals("") || name.equals(phone))
getAllContact.add(new MissingPhoneModelClass(phone, "No Name", id));
} else {
if(TextUtils.equals(phone,null)){
getAllContact.add(new MissingPhoneModelClass("No Number", name, id));
}
else {
getAllContact.add(new MissingPhoneModelClass(phone, name, id));
}
}
}
}
}
One thing can be done you have to give the permission in the manifest for contact READ and WRITE After that you can create the model class for the list which can be use to add all the contact here is the model class
public class PhoneModelClass {
private String number;
private String name;
private String id;
private String rawId;
public PhoneModelClass(String number, String name, String id, String rawId) {
this.number = number;
this.name = name;
this.id = id;
this.rawId = rawId;
}
public PhoneModelClass(String number, String name, String id) {
this.number = number;
this.name = name;
this.id = id;
}
public String getRawId() {
return rawId;
}
public void setRawId(String rawId) {
this.rawId = rawId;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}
Enjoy :)
To find the last filled column use the following :
lastColumn = ActiveSheet.Cells(1, Columns.Count).End(xlToLeft).Column
Also check /etc/exports
. If you are exporting paths within the mountpoint via NFS, it will give this error when trying to unmount and nothing will show up in fuser
or lsof
.
Sometimes the simple method is the best. Just pad your strings with spaces. If it is only a few textboxes etc this is by far the simplest method.
You can also simply insert blank columns/rows with a fixed size. Extremely simple and you can easily change it.
PECL XHPROF looks interensting too. It has clickable HTML interface for viewing reports and pretty straightforward documentation. I have yet to test it though.
You could create a dict comprehension of just the elements whose values are None, and then update back into the original:
tmp = dict((k,"") for k,v in mydict.iteritems() if v is None)
mydict.update(tmp)
Update - did some performance tests
Well, after trying dicts of from 100 to 10,000 items, with varying percentage of None values, the performance of Alex's solution is across-the-board about twice as fast as this solution.
A simple recursive method using reduce
from functools
and the add
operator on lists:
>>> from functools import reduce
>>> from operator import add
>>> flatten = lambda lst: [lst] if type(lst) is int else reduce(add, [flatten(ele) for ele in lst])
>>> flatten(l)
[1, 2, 3, 4, 5, 6, 7, 8, 9]
The function flatten
takes in lst
as parameter. It loops all the elements of lst
until reaching integers (can also change int
to float
, str
, etc. for other data types), which are added to the return value of the outermost recursion.
Recursion, unlike methods like for
loops and monads, is that it is a general solution not limited by the list depth. For example, a list with depth of 5 can be flattened the same way as l
:
>>> l2 = [[3, [1, 2], [[[6], 5], 4, 0], 7, [[8]], [9, 10]]]
>>> flatten(l2)
[3, 1, 2, 6, 5, 4, 0, 7, 8, 9, 10]
You can use Regular Expression too... it would be like:
SELECT * FROM myTable WHERE col1 REGEXP '^[0-9]+$';
Reference: http://dev.mysql.com/doc/refman/5.1/en/regexp.html
Leanest answer (.net 4.5 and later):

FilterStringChanged?.Invoke(null, EventArgs.Empty);
}
}
and XAML:

"Egg" is a single-file importable distribution format for Python-related projects.
"The Quick Guide to Python Eggs" notes that "Eggs are to Pythons as Jars are to Java..."
Eggs actually are richer than jars; they hold interesting metadata such as licensing details, release dependencies, etc.
You need to use a tool to view the HTTP headers sent with the file, something like LiveHTTPHeaders or HTTPFox are what I use. If the files are sent from the webserver without a MIME type, or with a default MIME type like text/plain, that might be what this error is about.
This works for me:
convert original.png -fuzz 10% -transparent white transparent.png
where the smaller the fuzz %, the closer to true white or conversely, the larger the %, the more variation from white is allowed to become transparent
You can use Visual Studio 2012.
Simply update your NuGet package in Visual Studio to Microsoft.AspNet.Mvc 5.0
.
You may have to search pre-release.
Also the default project comes with Entity Framework 6.0, and ASP.NET Razor 3.0.
You may also need ASP.NET Identity Core and OWIN.
All of these can be downloaded/updated through menu Tools ? Library package manager ? Manage NuGet Packages for Solution....
If you don't yet have NuGet, follow this tutorial:
Please use test flight to obtain UDID from testers but not using untrusted source e.g. http://get.udid.io/
You can 1. Invite testers in email from test flight webpage. Testers open the link in email and install a profile from test flight. Therefore developers can obtain UDIDs on the test flight webpage. 2. Add those UDIDs on the Apple provisioning portal.
(Ref: http://help.testflightapp.com/customer/portal/articles/829537-how-does-it-work-)
The process doesn't require testers to use Mac/ PC to obtain UDID (more convenient). And I think test flight is a company that can be trusted (no worries when passing UDID to this company).
I have tested this method and it works on iOS 8.
How about this ?
ViewModel:
class ViewModel
{
public Action CloseAction { get; set; }
private void Stuff()
{
// Do Stuff
CloseAction(); // closes the window
}
}
In your ViewModel use CloseAction() to close the window just like in the example above.
View:
public View()
{
InitializeComponent();
ViewModel vm = new ViewModel (); // this creates an instance of the ViewModel
this.DataContext = vm; // this sets the newly created ViewModel as the DataContext for the View
if (vm.CloseAction == null)
vm.CloseAction = new Action(() => this.Close());
}
Yesterday's date can be calculated as,
var prev_date = new Date();
prev_date.setDate(prev_date.getDate() - 1);
You have to check every ID in tableA against every ID in tableB. A fully featured RDBMS (such as Oracle) would be able to optimize that into an INDEX FULL FAST SCAN and not touch the table at all. I don't know whether H2's optimizer is as smart as that.
H2 does support the MINUS syntax so you should try this
select id from tableA
minus
select id from tableB
order by id desc
That may perform faster; it is certainly worth benchmarking.
I encountered some weird behaviour that did not reflect the actual code base so after some time trying several solutions, my problem was solved by manually deleting everything under /var/cache/tomcat8/
You can close a figure by calling matplotlib.pyplot.close
, for example:
from numpy import *
import matplotlib.pyplot as plt
from scipy import *
t = linspace(0, 0.1,1000)
w = 60*2*pi
fig = plt.figure()
plt.plot(t,cos(w*t))
plt.plot(t,cos(w*t-2*pi/3))
plt.plot(t,cos(w*t-4*pi/3))
plt.show()
plt.close(fig)
You can also close all open figures by calling matplotlib.pyplot.close("all")
This will solve purpose in fast and simple code.
It gives result in O(n)
.
void removeduplicate(char *str)
{
int checker = 0;
int cnt = 0;
for(int i = 0; i < strlen(str); i++)
{
int val = *(str + i) - (int)'a';
if ((checker & (1 << val)) > 0) continue;
else {
*(str + cnt) = *(str + i);
cnt++;
}
checker |= (1 << val);
}
*(str+cnt) = '\0';
}
Try this
String[] arr = list.toArray(new String[list.size()]);
The JMeter docs say the following:
The summary report creates a table row for each differently named request in your test. This is similar to the Aggregate Report , except that it uses less memory. The thoughput is calculated from the point of view of the sampler target (e.g. the remote server in the case of HTTP samples). JMeter takes into account the total time over which the requests have been generated. If other samplers and timers are in the same thread, these will increase the total time, and therefore reduce the throughput value. So two identical samplers with different names will have half the throughput of two samplers with the same name. It is important to choose the sampler labels correctly to get the best results from the Report.
Times are in milliseconds.

This is quite a misleading status. It should be called "reading and filtering data".
This means that MySQL
has some data stored on the disk (or in memory) which is yet to be read and sent over. It may be the table itself, an index, a temporary table, a sorted output etc.
If you have a 1M records table (without an index) of which you need only one record, MySQL
will still output the status as "sending data" while scanning the table, despite the fact it has not sent anything yet.
You could modify .adm
and add
.adm{
clear:both;
}
That should make it move to a new line
Use for...of:
var mycars = [{name:'Susita'}, {name:'BMW'}];
for (var car of mycars)

Result:
Susita
BMW
You can escape quotation like this:
select 'it''s escaped'
result will be

Just wrap it around then.

In addition to the accepted answer, you can also achieve what you originally wanted (creating a deployment using the run
command) with the following command:
kubectl run hdfs --image=fluxcapacitor/hdfs:latest --port=8989 --generator=run-pod/v1
I found the information about the generator on the Kubernetes-dev forum:
If you're using
kubectl run
, it generates a manifest for you that happens to haveimagePullPolicy
set toAlways
by default. You can use this command to get animagePullPolicy
ofIfNotPresent
, which will work forminikube
:
kubectl run --image=<container> --generator=run-pod/v1

If you want to take just two numbers after comma you can use the Math Class that give you the round function for example :
float value = 92.197354542F;
value = (float)System.Math.Round(value,2); // value = 92.2;
Hope this Help

This can also happen if you have the wrong python27.dll file (in case of Windows), to solve this just re-install (or extract) python with the exact corresponding dll version. I had a similar experience.
the Jquery append function returns a jQuery object so you can just tag a method on the end
$("#root").append(child).anotherJqueryMethod();
If you need to insert into a specific position in the array, you can do this:
case ADD_ITEM :
return {
...state,
arr: [
...state.arr.slice(0, action.pos),
action.newItem,
...state.arr.slice(action.pos),
],
}
The recommended approach for a singleton service for Angular 6 and beyond is :
import { Injectable } from '@angular/core';
@Injectable({
providedIn: 'root',
})
export class UserService {
}
In fact the CLI --module
switch doesn't even exist any more for registering a service at the app
level because it doesn't need to modify app.module.ts
anymore.
This will create the above code, without needing to specify a module.
ng g s services/user
So if you don't want your service to be a singleton you must remove the providedIn
code yourself - and then add it manually to providers
for a component or lazy loaded module. Doesn't look like there is currently a switch to not generate the providedIn: 'root'
part so you need to manually remove it.
In case where pwd can't be used (e.g. calling a scripts from a different location), use realpath (with or without dirname):
$(dirname $(realpath $PATH_TO_BE_RESOLVED))
Works both when calling through (multiple) symlink(s) or when directly calling the script - from any location.

You probablly have 2 different versions of hibernate-jpa-api on the classpath. To check that run:
mvn dependency:tree >dep.txt
Then search if there are hibernate-jpa-2.0-api and hibernate-jpa-2.1-api. And exclude the excess one.
Yes Fiddler is an option for me:
CustomRules.js
).OnBeforeResponse
Add the following lines:
oSession.oResponse.headers.Remove("X-Frame-Options");

Here's another, perhaps more familiar-looking way to do it:
for i in (0..10).step(2) do
puts i
end
A class contains data field descriptions (or properties, fields, data members, attributes), i.e., field types and names, that will be associated with either per-instance or per-class state variables at program run time.
This worked for me: (bootstrap 3.3.6; jquery=1.11.3)
<a id="alertTooltip" href="#" data-html="true" class="tooltip" data-toggle="tooltip" title="Tooltip message"></a>
<script>
$('#alertTooltip').attr('title', "Tooltip new <br /> message").tooltip('fixTitle');
</script>
The attribute data-html="true"
allow to use html on the tooltip title.
You can embed the assembly code in a normal C program. Here's a good introduction. Using the appropriate syntax, you can also tell GCC you want to interact with variables declared in C. The program below instructs gcc that:
\n
int main(void)
{
int foo = 10, bar = 15;
__asm__ __volatile__("addl %%ebx,%%eax"
:"=a"(foo)
:"a"(foo), "b"(bar)
);
printf("foo+bar=%d\n", foo);
return 0;
}
tableB.col1 = tableA.col1
OR tableB.col2 = tableA.col1
OR tableB.col1 = tableA.col2
OR tableB.col1 = tableA.col2
Check This Example
Html:
<div class="buttons">
<a class="button" id="showall">All</a>
<a class="button" id="showdiv1">Div 1</a>
<a class="button" id="showdiv2">Div 2</a>
<a class="button" id="showdiv3">Div 3</a>
<a class="button" id="showdiv4">Div 4</a>
</div>
<div id="div1">1</div>
<div id="div2">2</div>
<div id="div3">3</div>
<div id="div4">4</div>
Javascript:
$('#showall').click(function(){
$('div').show();
});
$('#showdiv1').click(function(){
$('div[id^=div]').hide();
$('#div1').show();
});
$('#showdiv2').click(function(){
$('div[id^=div]').hide();
$('#div2').show();
});
$('#showdiv3').click(function(){
$('div[id^=div]').hide();
$('#div3').show();
});
$('#showdiv4').click(function(){
$('div[id^=div]').hide();
$('#div4').show();
});

You need to create a Handler
in the UI thread and then use it to post or send a message from your other thread to update the UI
I would suggest instead of creating a new table, you just use a view that combines the two tables, this way if any of the data in table 1 or table 2 changes, you don't need to update the third table:
CREATE VIEW dbo.YourView
AS
SELECT t1.Name, t1.Age, t1.Sex, t1.City, t1.ID, t2.Number
FROM Table1 t1
INNER JOIN Table2 t2
ON t1.ID = t2.ID;
If you could have records in one table, and not in the other, then you would need to use a full join:
CREATE VIEW dbo.YourView
AS
SELECT t1.Name, t1.Age, t1.Sex, t1.City, ID = ISNULL(t1.ID, t2.ID), t2.Number
FROM Table1 t1
FULL JOIN Table2 t2
ON t1.ID = t2.ID;
If you know all records will be in table 1 and only some in table 2, then you should use a LEFT JOIN
:
CREATE VIEW dbo.YourView
AS
SELECT t1.Name, t1.Age, t1.Sex, t1.City, t1.ID, t2.Number
FROM Table1 t1
LEFT JOIN Table2 t2
ON t1.ID = t2.ID;
If you know all records will be in table 2 and only some in table 2 then you could use a RIGHT JOIN
CREATE VIEW dbo.YourView
AS
SELECT t1.Name, t1.Age, t1.Sex, t1.City, t2.ID, t2.Number
FROM Table1 t1
RIGHT JOIN Table2 t2
ON t1.ID = t2.ID;
Or just reverse the order of the tables and use a LEFT JOIN (I find this more logical than a right join but it is personal preference):
CREATE VIEW dbo.YourView
AS
SELECT t1.Name, t1.Age, t1.Sex, t1.City, t2.ID, t2.Number
FROM Table2 t2
LEFT JOIN Table1 t1
ON t1.ID = t2.ID;
?hange USB connection mode from MTP to Camera (for Nexus 7) or, possibly, to Mass Storage or something else (for other devices). This option is usually under Settings -> Storage
. Then connect the device again, you'll get the authorization dialog.
MTP has been known to interfere with USB debugging -- these two did not work together at all on majority of older devices. Nexus 7 and many newer devices do allow both to work alongside, but this particular issue suggests it's not all that smooth yet.

My ngninx logs are located here:
/usr/local/var/log/nginx/*
You can also check your nginx.conf
to see if you have any directives dumping to custom log.
run nginx -t
to locate your nginx.conf
.
# in ngingx.conf
error_log /usr/local/var/log/nginx/error.log;
error_log /usr/local/var/log/nginx/error.log notice;
error_log /usr/local/var/log/nginx/error.log info;
Nginx is usually set up in /usr/local
or /etc/
. The server could be configured to dump logs to /var/log
as well.
If you have an alternate location for your nginx install and all else fails, you could use the find
command to locate your file of choice.
find /usr/ -path "*/nginx/*" -type f -name '*.log'
, where /usr/
is the folder you wish to start searching from.
when I ran (as suggested above):
>>> a = [(1, u'abc'), (2, u'def')]
>>> import operator
>>> b = map(operator.itemgetter(0), a)
>>> b
instead of returning:
[1, 2]
I received this as the return:
<map at 0xb387eb8>
I found I had to use list():
>>> b = list(map(operator.itemgetter(0), a))
to successfully return a list using this suggestion. That said, I'm happy with this solution, thanks. (tested/run using Spyder, iPython console, Python v3.6)
The macros defined in <inttypes.h>
are the most correct way to print values of types uint32_t
, uint16_t
, and so forth -- but they're not the only way.
Personally, I find those macros difficult to remember and awkward to use. (Given the syntax of a printf
format string, that's probably unavoidable; I'm not claiming I could have come up with a better system.)
An alternative is to cast the values to a predefined type and use the format for that type.
Types int
and unsigned int
are guaranteed by the language to be at least 16 bits wide, and therefore to be able to hold any converted value of type int16_t
or uint16_t
, respectively. Similarly, long
and unsigned long
are at least 32 bits wide, and long long
and unsigned long long
are at least 64 bits wide.
For example, I might write your program like this (with a few additional tweaks):
#include <stdio.h>
#include <stdint.h>
#include <netinet/in.h>
int main(void)
{
uint32_t a=12, a1;
uint16_t b=1, b1;
a1 = htonl(a);
printf("%lu---------%lu\n", (unsigned long)a, (unsigned long)a1);
b1 = htons(b);
printf("%u-----%u\n", (unsigned)b, (unsigned)b1);
return 0;
}
One advantage of this approach is that it can work even with pre-C99 implementations that don't support <inttypes.h>
. Such an implementation most likely wouldn't have <stdint.h>
either, but the technique is useful for other integer types.
If you need multiple modifications, like when using ant design, you can combine multiple functions like this:
const {
override,
removeModuleScopePlugin,
fixBabelImports,
} = require('customize-cra');
module.exports = override(
fixBabelImports('import', {
libraryName: 'antd',
libraryDirectory: 'es',
style: 'css',
}),
removeModuleScopePlugin(),
);

recyclerView = (RecyclerView) findViewById(R.id.rv_followers_list);
to
recyclerView = (RecyclerView) findViewById(R.id.rv_search_list);
My preference is to encode all non-alphaumeric characters as HTML numeric character entities. Since almost, if not all attacks require non-alphuneric characters (like <, ", etc) this should eliminate a large chunk of dangerous output.
Format is &#N;, where N is the numeric value of the character (you can just cast the character to an int and concatenate with a string to get a decimal value). For example:
// java-ish pseudocode StringBuffer safestrbuf = new StringBuffer(string.length()*4); foreach(char c : string.split() ){ if( Character.isAlphaNumeric(c) ) safestrbuf.append(c); else safestrbuf.append(""+(int)symbol);
You will also need to be sure that you are encoding immediately before outputting to the browser, to avoid double-encoding, or encoding for HTML but sending to a different location.
There is no collision in your example. You use the same key, so the old value gets replaced with the new one. Now, if you used two keys that map to the same hash code, then you'd have a collision. But even in that case, HashMap would replace your value! If you want the values to be chained in case of a collision, you have to do it yourself, e.g. by using a list as a value.
Best aproach for me was:
private void grid_receptie_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
int X = 1;
foreach(DataGridViewRow row in grid_receptie.Rows)
{
row.Cells["NR_CRT"].Value = X;
X++;
}
}
A personal example using mysql 5.5: I had an inner join between 2 tables, one of 3 million rows and one of 10 thousand rows.
When using a like on an index as below(no wildcards), it took about 30 seconds:
where login like '12345678'
using 'explain' I get:
When using an '=' on the same query, it took about 0.1 seconds:
where login ='600009'
Using 'explain' I get:
As you can see, the like
completely cancelled the index seek, so query took 300 times more time.

According to the GCC manual for omp_get_num_threads:
In a sequential section of the program omp_get_num_threads returns 1
So this:
cout<<"sum="<<sum<<endl;
cout<<"threads="<<omp_get_num_threads()<<endl;
Should be changed to something like:
#pragma omp parallel
{
cout<<"sum="<<sum<<endl;
cout<<"threads="<<omp_get_num_threads()<<endl;
}
The code I use follows Hristo's advice of disabling dynamic teams, too.
The program will not work properly because at Line 1, when the user presses Enter, it will leave in the input buffer 2 character: Enter key (ASCII code 13) and \n (ASCII code 10). Therefore, at Line 2, it will read the \n and will not wait for the user to enter a character.
The behavior you see at line 2 is correct, but that's not quite the correct explanation. With text-mode streams, it doesn't matter what line-endings your platform uses (whether carriage return (0x0D) + linefeed (0x0A), a bare CR, or a bare LF). The C runtime library will take care of that for you: your program will see just '\n'
for newlines.
If you typed a character and pressed enter, then that input character would be read by line 1, and then '\n'
would be read by line 2. See I'm using scanf %c
to read a Y/N response, but later input gets skipped. from the comp.lang.c FAQ.
As for the proposed solutions, see (again from the comp.lang.c FAQ):
fflush(stdin)
work? fflush
won't work, what can I use to flush input?which basically state that the only portable approach is to do:
int c;
while ((c = getchar()) != '\n' && c != EOF) { }
Your getchar() != '\n'
loop works because once you call getchar()
, the returned character already has been removed from the input stream.
Also, I feel obligated to discourage you from using scanf
entirely: Why does everyone say not to use scanf
? What should I use instead?
Since some codes gave a wrong result for Edge and Opera, I suggest to try this code:
$popularBrowsers = ["Opera","OPR/", "Edg", "Chrome", "Safari", "Firefox", "MSIE", "Trident"];
$userAgent = $_SERVER['HTTP_USER_AGENT'];
$userBrowser = 'Other less popular browsers';
foreach ($popularBrowsers as $browser) {
if (strpos($userAgent, $browser) !== false) {
$userBrowser = $browser;
break;
}
}
switch ($userBrowser) {
case 'OPR/':
$userBrowser = 'Opera';
break;
case 'MSIE':
$userBrowser = 'Internet Explorer';
break;
case 'Trident':
$userBrowser = 'Internet Explorer';
break;
case 'Edg':
$userBrowser = 'Microsoft Edge';
break;
}
echo "Your browser: " . $userBrowser;

Convenient tool for SVG encoding url-encoder
You can use one and more echo statement inside href
<a href="profile.php?usr=<?php echo $_SESSION['firstname']."&email=". $_SESSION['email']; ?> ">Link</a>
link : "/profile.php?usr=firstname&email=email"
I have had a similar problem and this is how i solved it using the examples above:
$(".ms-drop").click(function () {
$(function showSelectedValues() {
alert($(".ms-drop input[type=checkbox]:checked").map(
function () { return this.value; }).get().join(","));
});
});
What I'd try first is
to drop all constraints, indexes, triggers and full text indexes first before you update.
If above wasn't performant enough, my next move would be
to create a CSV file with 12 million records and bulk import it using bcp.
Lastly, I'd create a new heap table (meaning table with no primary key) with no indexes on a different filegroup, populate it with -1. Partition the old table, and add the new partition using "switch".
Im a bit late to the party and I know the OP said html, but if you needed to do this in MVC you can set true
in the third param.
eg:
<p>Option One :@Html.RadioButton("options", "option1", true})</p>
// true will set it checked
<p>Option Two :@Html.RadioButton("options", "option2"})</p>
//nothing will leave it unchecked
Public Function TestError() As String()

Works fine for me and should work for you, but you may need allow using implicit declarations in your project. I believe this is turning off Options strict in the Compile section of the program settings.
Since you are using VS 2008 (VB.NET 9.0) you have to declare create the new instance
New String() {"foo", "Bar"}
#pragma
is for compiler directives that are machine-specific or operating-system-specific, i.e. it tells the compiler to do something, set some option, take some action, override some default, etc. that may or may not apply to all machines and operating systems.

I don't see any margin
or margin-left
declarations for #footer-wrap li

This ought to do the trick:
#footer-wrap ul,
#footer-wrap li {
margin-left: 0;
list-style-type: none;
}
Full version:
<? echo date('F Y'); ?>
Short version:
<? echo date('M Y'); ?>
Here is a good reference for the different date options.
update
To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp
parameter for the date() function. Like this:
echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));
This will also work (it's typically used to get the last day of the previous month):
echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));
Hope that helps.
You can just do it in your Activity's onCreate() method. For example:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//Assign the button to a variable
Button button1 = (Button)findViewById(R.id.button1);
//Assign the ImageView to a final variable, so that it's
//accessible from an inner class
ImageView imageView = (ImageView)findViewById(R.id.imageview1);
//Assign it a new OnClickListener
button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
imageView.setVisibility(View.VISIBLE);
}
}
}
X-XSS-Protection is a HTTP header understood by Internet Explorer 8 (and newer versions). This header lets domains toggle on and off the "XSS Filter" of IE8, which prevents some categories of XSS attacks. IE8 has the filter activated by default, but servers can switch if off by setting
X-XSS-Protection: 0
If Primary Key and type needed, this query may be useful:
SELECT L.TABLE_SCHEMA, L.TABLE_NAME, L.COLUMN_NAME, R.TypeName
FROM(
SELECT COLUMN_NAME, TABLE_NAME, TABLE_SCHEMA
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE OBJECTPROPERTY(OBJECT_ID(CONSTRAINT_SCHEMA + '.' + QUOTENAME(CONSTRAINT_NAME)), 'IsPrimaryKey') = 1
)L
LEFT JOIN (
SELECT
OBJECT_NAME(c.OBJECT_ID) TableName ,c.name AS ColumnName ,t.name AS TypeName
FROM sys.columns AS c
JOIN sys.types AS t ON c.user_type_id=t.user_type_id
)R ON L.COLUMN_NAME = R.ColumnName AND L.TABLE_NAME = R.TableName
For anyone arriving here wondering how to deal with this problem where commas (,
) and full stops (.
) might be involved but the exact number format may not be known - this is how I correct a string before using parseFloat()
(borrowing ideas from other answers):
function preformatFloat(float){
if(!float){
return '';
};
//Index of first comma
const posC = float.indexOf(',');
if(posC === -1){
//No commas found, treat as float
return float;
};
//Index of first full stop
const posFS = float.indexOf('.');
if(posFS === -1){
//Uses commas and not full stops - swap them (e.g. 1,23 --> 1.23)
return float.replace(/\,/g, '.');
};
//Uses both commas and full stops - ensure correct order and remove 1000s separators
return ((posC < posFS) ? (float.replace(/\,/g,'')) : (float.replace(/\./g,'').replace(',', '.')));
};
// <-- parseFloat(preformatFloat('5.200,75'))
// --> 5200.75
At the very least, this would allow parsing of British/American and European decimal formats (assuming the string contains a valid number).
You should remove the '@' before 'name'; it's not needed anymore (for current jQuery versions).
You're want to return all checked elements with name 'test2', but you don't have any elements with that name, you're using an id of 'test2'.
If you're going to use IDs, just try:
return $('#test2').attr('checked');
you can solve it

I made an experiment using the magic method __call. Not sure if I should post it (because of all the "DO NOT USE MAGIC METHODS" warnings in the other answers and comments) but i'll leave it here.. just in case someone find it useful.
public function __call($_name, $_arguments){
$action = substr($_name, 0, 4);
$varName = substr($_name, 4);
if (isset($this->{$varName})){
if ($action === "get_") return $this->{$varName};
if ($action === "set_") $this->{$varName} = $_arguments[0];
}
}
Just add that method above in your class, now you can type:
class MyClass{
private foo = "bar";
private bom = "bim";
// ...
// public function __call(){ ... }
// ...
}
$C = new MyClass();
// as getter
$C->get_foo(); // return "bar"
$C->get_bom(); // return "bim"
// as setter
$C->set_foo("abc"); // set "abc" as new value of foo
$C->set_bom("zam"); // set "zam" as new value of bom
This way you can get/set everything in your class if it exist so, if you need it for only a few specific elements, you could use a "whitelist" as filter.
Example:
private $callWhiteList = array(
"foo" => "foo",
"fee" => "fee",
// ...
);
public function __call($_name, $_arguments){
$action = substr($_name, 0, 4);
$varName = $this->callWhiteList[substr($_name, 4)];
if (!is_null($varName) && isset($this->{$varName})){
if ($action === "get_") return $this->{$varName};
if ($action === "set_") $this->{$varName} = $_arguments[0];
}
}
Now you can only get/set "foo" and "fee".
You can also use that "whitelist" to assign custom names to access to your vars.
For example,
private $callWhiteList = array(
"myfoo" => "foo",
"zim" => "bom",
// ...
);
With that list you can now type:
class MyClass{
private foo = "bar";
private bom = "bim";
// ...
// private $callWhiteList = array( ... )
// public function __call(){ ... }
// ...
}
$C = new MyClass();
// as getter
$C->get_myfoo(); // return "bar"
$C->get_zim(); // return "bim"
// as setter
$C->set_myfoo("abc"); // set "abc" as new value of foo
$C->set_zim("zam"); // set "zam" as new value of bom
.
.
.
That's all.
Doc: __call() is triggered when invoking inaccessible methods in an object context.
path.resolve('.')
is also a reliable and clean option, because we almost always require('path')
. It will give you absolute path of the directory from where it is called.
html, body {
min-height: 100%;
}
Will do the trick.
By default, even html and body are only as big as the content they hold, but never more than the width/height of the windows. This can often lead to quite strange results.

export PATH=$PATH:/usr/local/git/bin:/usr/local/bin
One note: you don't need quotation marks here because it's on the right hand side of an assignment, but in general, and especially on Macs with their tradition of spacy pathnames, expansions like $PATH
should be double-quoted as "$PATH"
.
I find this type of approach works for me:
Product ProductDetail Country ========= ================== ========= ProductId ProductDetailId CountryId - etc - ProductId CountryName CountryId Language ProductName - etc - ProductDescription - etc -
The ProductDetail table holds all the translations (for product name, description etc..) in the languages you want to support. Depending on your app's requirements, you may wish to break the Country table down to use regional languages too.
One solution that I haven't seen mentioned here, is using session storage instead of cookies. Of course this might not fit everyone's requirements, but for some cases it's an easy fix.
In the interests of completeness there are a couple of other solutions which (in my opinion) are more orthodox than solutions relying on the SqlDependency (and SqlTableDependency) classes. SqlDependency was originally designed to make refreshing distributed webserver caches easier, and so was built to a different set of requirements than if it were designed as an event producer.
There are broadly four options, some of which have not been covered here already:
Change tracking
Change tracking is a lightweight notification mechanism in SQL server. Basically, a database-wide version number is incremented with every change to any data. The version number is then written to the change tracking tables with a bit mask including the names of the columns which were changed. Note, the actual change is not persisted. The notification only contains the information that a particular data entity has changed. Further, because the change table versioning is cumulative, change notifications on individual items are not preserved and are overwritten by newer notifications. This means that if an entity changes twice, change tracking will only know about the most recent change.
In order to capture these changes in c#, polling must be used. The change tracking tables can be polled and each change inspected to see if is of interest. If it is of interest, it is necessary to then go directly to the data to retrieve the current state.
Change Data Capture
Source: https://technet.microsoft.com/en-us/library/bb522489(v=sql.105).aspx
Change data capture (CDC) is more powerful but most costly than change tracking. Change data capture will track and notify changes based on monitoring the database log. Because of this CDC has access to the actual data which has been changed, and keeps a record of all individual changes.
Similarly to change tracking, in order to capture these changes in c#, polling must be used. However, in the case of CDC, the polled information will contain the change details, so it's not strictly necessary to go back to the data itself.
Triggers to queues
Source: https://code.msdn.microsoft.com/Service-Broker-Message-e81c4316
This technique depends on triggers on the tables from which notifications are required. Each change will fire a trigger, and the trigger will write this information to a service broker queue. The queue can then be connected to via C# using the Service Broker Message Processor (sample in the link above).
Unlike change tracking or CDC, triggers to queues do not rely on polling and thereby provides realtime eventing.
CLR
This is a technique I have seen used, but I would not recommend it. Any solution which relies on the CLR to communicate externally is a hack at best. The CLR was designed to make writing complex data processing code easier by leveraging C#. It was not designed to wire in external dependencies like messaging libraries. Furthermore, CLR bound operations can break in clustered environments in unpredictable ways.
This said, it is fairly straightforward to set up, as all you need to do is register the messaging assembly with CLR and then you can call away using triggers or SQL jobs.
In summary...
It has always been a source of amazement to me that Microsoft has steadfastly refused to address this problem space. Eventing from database to code should be a built-in feature of the database product. Considering that Oracle Advanced Queuing combined with the ODP.net MessageAvailable event provided reliable database eventing to C# more than 10 years ago, this is woeful from MS.
The upshot of this is that none of the solutions listed to this question are very nice. They all have technical drawbacks and have a significant setup cost. Microsoft if you're listening, please sort out this sorry state of affairs.
The message is clear: you have a repeated column in the mapping. That means you mapped the same database column twice. And indeed, you have:
@Column(nullable=false)
private Long customerId;
and also:
@ManyToOne(optional=false)
@JoinColumn(name="customerId",referencedColumnName="id_customer")
private Customer customer;
(and the same goes for productId
/product
).
You shouldn't reference other entities by their ID, but by a direct reference to the entity. Remove the customerId
field, it's useless. And do the same for productId
. If you want the customer ID of a sale, you just need to do this:
sale.getCustomer().getId()
Deprecated in general means "don't use it".
A deprecated function may or may not work, but it is not guaranteed to work.
To create a "drop down menu" you can use OptionMenu
in tkinter
Example of a basic OptionMenu
:
from Tkinter import *
master = Tk()
variable = StringVar(master)
variable.set("one") # default value
w = OptionMenu(master, variable, "one", "two", "three")
w.pack()
mainloop()
More information (including the script above) can be found here.
Creating an OptionMenu
of the months from a list would be as simple as:
from tkinter import *
OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc
master = Tk()
variable = StringVar(master)
variable.set(OPTIONS[0]) # default value
w = OptionMenu(master, variable, *OPTIONS)
w.pack()
mainloop()
In order to retrieve the value the user has selected you can simply use a .get()
on the variable that we assigned to the widget, in the below case this is variable
:
from tkinter import *
OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc
master = Tk()
variable = StringVar(master)
variable.set(OPTIONS[0]) # default value
w = OptionMenu(master, variable, *OPTIONS)
w.pack()
def ok():
print ("value is:" + variable.get())
button = Button(master, text="OK", command=ok)
button.pack()
mainloop()
I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.
There is very good package available to parse the email contents with proper documentation.
import mailparser
mail = mailparser.parse_from_file(f)
mail = mailparser.parse_from_file_obj(fp)
mail = mailparser.parse_from_string(raw_mail)
mail = mailparser.parse_from_bytes(byte_mail)
How to Use:
mail.attachments: list of all attachments
mail.body
mail.to
Here are few examples from PostgreSQL-9.5

There are different ways we can pass the Access-Control-Expose-Headers.
Another way is we can add code as below in the webApiconfig.cs file.
config.EnableCors(new EnableCorsAttribute("", headers: "", methods: "*",exposedHeaders: "TestHeaderToExpose") { SupportsCredentials = true });
Or we can add below code in the Global.Asax file.
protected void Application_BeginRequest()
{
if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
{
//These headers are handling the "pre-flight" OPTIONS call sent by the browser
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST, OPTIONS");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "*");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Credentials", "true");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "http://localhost:4200");
HttpContext.Current.Response.AddHeader("Access-Control-Expose-Headers", "TestHeaderToExpose");
HttpContext.Current.Response.End();
}
}
I have written it for the options. Please modify the same as per your need.
Happy Coding !!
I guess the below should work (instead of the writer part from your example). I'm unfortunately with no build environment so It's from memory but I hope it helps
using (var fs = File.Open(filePath, FileMode.Open, FileAccess.ReadWrite)))
{
var destinationReader = StreamReader(fs);
var writer = StreamWriter(fs);
while ((line = reader.ReadLine()) != null)
{
if (line_number == line_to_edit)
{
writer.WriteLine(lineToWrite);
}
else
{
destinationReader .ReadLine();
}
line_number++;
}
}
Open the command prompt as administrator and navigate to the project location and then run npm install. it worked for me.
I am not sure whether I understood your intentions correctly, but let's see if this one helps.
public class TypedProperty<T> : Property where T : IConvertible
{
public T TypedValue
{
get { return (T)Convert.ChangeType(base.Value, typeof(T)); }
set { base.Value = value.ToString();}
}
}
Differently than everyone else did using regex, I would try to exclude every character that is not what I want, instead of enumerating explicitly what I don't want.
For example, if I want only characters from 'a to z' (upper and lower case) and numbers, I would exclude everything else:
import re
s = re.sub(r"[^a-zA-Z0-9]","",s)
This means "substitute every character that is not a number, or a character in the range 'a to z' or 'A to Z' with an empty string".
In fact, if you insert the special character ^
at the first place of your regex, you will get the negation.
Extra tip: if you also need to lowercase the result, you can make the regex even faster and easier, as long as you won't find any uppercase now.
import re
s = re.sub(r"[^a-z0-9]","",s.lower())
I am combining the solutions from answers of @FredFoo and @Renaud. My solution is able to apply @Renaud's preprocessing on the text corpus of @FredFoo and then display pairwise similarities where the similarity is greater than 0. I ran this code on Windows by installing python and pip first. pip is installed as part of python but you may have to explicitly do it by re-running the installation package, choosing modify and then choosing pip. I use the command line to execute my python code saved in a file "similarity.py". I had to execute the following commands:
>set PYTHONPATH=%PYTHONPATH%;C:\_location_of_python_lib_
>python -m pip install sklearn
>python -m pip install nltk
>py similarity.py
The code for similarity.py is as follows:
from sklearn.feature_extraction.text import TfidfVectorizer
import nltk, string
import numpy as np
nltk.download('punkt') # if necessary...
stemmer = nltk.stem.porter.PorterStemmer()
remove_punctuation_map = dict((ord(char), None) for char in string.punctuation)
def stem_tokens(tokens):
return [stemmer.stem(item) for item in tokens]
def normalize(text):
return stem_tokens(nltk.word_tokenize(text.lower().translate(remove_punctuation_map)))
corpus = ["I'd like an apple",
"An apple a day keeps the doctor away",
"Never compare an apple to an orange",
"I prefer scikit-learn to Orange",
"The scikit-learn docs are Orange and Blue"]
vect = TfidfVectorizer(tokenizer=normalize, stop_words='english')
tfidf = vect.fit_transform(corpus)
pairwise_similarity = tfidf * tfidf.T
#view the pairwise similarities
print(pairwise_similarity)
#check how a string is normalized
print(normalize("The scikit-learn docs are Orange and Blue"))
Another variation of this bug: I had a function named 'continue' and since it's a reserved word it threw this error. I had to rename my function 'continueClick'
You can export the date using this command.
<?php
$list = array (
array('aaa', 'bbb', 'ccc', 'dddd'),
array('123', '456', '789'),
array('"aaa"', '"bbb"')
);
$fp = fopen('file.csv', 'w');
foreach ($list as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);
?>
First you must load the data from the mysql server in to a array
Heres my way of doing it, using square method. upside is it works with different values, but you need 2 spans.
