use:
/^[ A-Za-z0-9_@./#&+-]*$/
You can also use the character class \w to replace A-Za-z0-9_
X-code is primarily made for OS-X or iPhone development on Mac systems. Versions for Windows are not available. However this might help!
There is no way to get Xcode on Windows; however you can use a different SDK like Corona instead although it will not use Objective-C (I believe it uses Lua). I have however heard that it is horrible to use.

You can build random ascii characters like:
import random
print chr(random.randint(0,255))
And then build up a longer string like:
len = 50
print ''.join( [chr(random.randint(0,255)) for i in xrange(0,len)] )
There is something wrong with your code.
position : absolute
makes the element on top irrespective of other elements in the same page. But the position not relative to the scroll
This can be solved with position : fixed
This property will make the element position fixed and still relative to the scroll.
Or
You can check it out Here
r = R * sqrt(random())
theta = random() * 2 * PI
(Assuming random()
gives a value between 0 and 1 uniformly)
If you want to convert this to Cartesian coordinates, you can do
x = centerX + r * cos(theta)
y = centerY + r * sin(theta)
sqrt(random())
?Let's look at the math that leads up to sqrt(random())
. Assume for simplicity that we're working with the unit circle, i.e. R = 1.
The average distance between points should be the same regardless of how far from the center we look. This means for example, that looking on the perimeter of a circle with circumference 2 we should find twice as many points as the number of points on the perimeter of a circle with circumference 1.
Since the circumference of a circle (2πr) grows linearly with r, it follows that the number of random points should grow linearly with r. In other words, the desired probability density function (PDF) grows linearly. Since a PDF should have an area equal to 1 and the maximum radius is 1, we have
So we know how the desired density of our random values should look like. Now: How do we generate such a random value when all we have is a uniform random value between 0 and 1?
We use a trick called inverse transform sampling
Sounds complicated? Let me insert a blockquote with a little side track that conveys the intuition:
Suppose we want to generate a random point with the following distribution:
That is
- 1/5 of the points uniformly between 1 and 2, and
- 4/5 of the points uniformly between 2 and 3.
The CDF is, as the name suggests, the cumulative version of the PDF. Intuitively: While PDF(x) describes the number of random values at x, CDF(x) describes the number of random values less than x.
In this case the CDF would look like:
To see how this is useful, imagine that we shoot bullets from left to right at uniformly distributed heights. As the bullets hit the line, they drop down to the ground:
See how the density of the bullets on the ground correspond to our desired distribution! We're almost there!
The problem is that for this function, the y axis is the output and the x axis is the input. We can only "shoot bullets from the ground straight up"! We need the inverse function!
This is why we mirror the whole thing; x becomes y and y becomes x:
We call this CDF-1. To get values according to the desired distribution, we use CDF-1(random()).
…so, back to generating random radius values where our PDF equals 2x.
Step 1: Create the CDF:
Since we're working with reals, the CDF is expressed as the integral of the PDF.
CDF(x) = ? 2x = x2
Step 2: Mirror the CDF along y = x:
Mathematically this boils down to swapping x and y and solving for y:
CDF: y = x2
Swap: x = y2
Solve: y = √x
CDF-1: y = √x
Step 3: Apply the resulting function to a uniform value between 0 and 1
CDF-1(random()) = √random()
Which is what we set out to derive :-)

This answers is for command needed for undoing local changes which are in multiple specific files in same or multiple folders (or directories). This answers specifically addresses question where a user has more than one file but the user doesn't want to undo all local changes:
if you have one or more files you could apply the same command (
git checkout -- file
) to each of those files by listing each of their location separated by space as in:
git checkout -- name1/name2/fileOne.ext nameA/subFolder/fileTwo.ext
mind the space above between name1/name2/fileOne.ext nameA/subFolder/fileTwo.ext
For multiple files in the same folder:
If you happen to need to discard changes for all of the files in a certain directory, use the git checkout as follows:
git checkout -- name1/name2/*
The asterisk in the above does the trick of undoing all files at that location under name1/name2.
And, similarly the following can undo changes in all files for multiple folders:
git checkout -- name1/name2/* nameA/subFolder/*
again mind the space between name1/name2/* nameA/subFolder/* in the above.
Note: name1, name2, nameA, subFolder - all of these example folder names indicate the folder or package where the file(s) in question may be residing.
In short there's no way to recover the passphrase for a pair of SSH keys. Why? Because it was intended this way in the first place for security reasons. The answers the other people gave you are all correct ways to CHANGE the password of your keys, not to recover them. So if you've forgotten your passphrase, the best you can do is create a new pair of SSH keys. Here's how to generate SSH keys and add it to your GitHub account.
You can simply call it:
SubGraphButton_Click(sender, args);
Now, if your SubGraphButton_Click
does something with the args, you might be in trouble, but usually you don't do anything with them.
It seems to be a long issue. All we want is just implement a select tag in the input group. But the bootstrap would not do it: https://github.com/twbs/bootstrap/issues/10486
the trick is just adding "btn-group" class to the parent div
html:
<div class="input-group">
<div class="input-group-btn btn-group">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
Product Name <span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu">
<li><a href="#">A</a></li>
<li><a href="#">B</a></li>
</ul>
</div>
<input type="text" class="form-control">
<span class="input-group-btn">
<button class="btn btn-primary" type="button">Search</button>
</span>
</div>
js:
$(".dropdown-menu li a").click(function(e){
var selText = $(this).text();
$(this).parents('.input-group').find('.dropdown-toggle').html(selText+' <span class="caret"></span>');
});
Just don't ever use null. Don't allow it.
In my classes, most fields and local variables have non-null default values, and I add contract statements (always-on asserts) everywhere in the code to make sure this is being enforced (since it's more succinct, and more expressive than letting it come up as an NPE and then having to resolve the line number, etc.).
Once I adopted this practice, I noticed that the problems seemed to fix themselves. You'd catch things much earlier in the development process just by accident and realize you had a weak spot.. and more importantly.. it helps encapsulate different modules' concerns, different modules can 'trust' each other, and no more littering the code with if = null else
constructs!
This is defensive programming and results in much cleaner code in the long run. Always sanitize the data, e.g. here by enforcing rigid standards, and the problems go away.
class C {
private final MyType mustBeSet;
public C(MyType mything) {
mustBeSet=Contract.notNull(mything);
}
private String name = "<unknown>";
public void setName(String s) {
name = Contract.notNull(s);
}
}
class Contract {
public static <T> T notNull(T t) { if (t == null) { throw new ContractException("argument must be non-null"); return t; }
}
The contracts are like mini-unit tests which are always running, even in production, and when things fail, you know why, rather than a random NPE you have to somehow figure out.
Assuming the hash of the commit you want is c5f567
:
git checkout c5f567 -- file1/to/restore file2/to/restore
The git checkout man page gives more information.
If you want to revert to the commit before c5f567
, append ~1
(where 1 is the number of commits you want to go back, it can be anything):
git checkout c5f567~1 -- file1/to/restore file2/to/restore
As a side note, I've always been uncomfortable with this command because it's used for both ordinary things (changing between branches) and unusual, destructive things (discarding changes in the working directory).

i've used the $templateCache to accomplish something similar. i put several ng-templates in a single html file, which i reference using the directive's templateUrl. that ensures the html is available to the template cache. then i can simply select by id to get the ng-template i want.
template.html:
<script type="text/ng-template" id=“foo”>
foo
</script>
<script type="text/ng-template" id=“bar”>
bar
</script>
directive:
myapp.directive(‘foobardirective’, ['$compile', '$templateCache', function ($compile, $templateCache) {
var getTemplate = function(data) {
// use data to determine which template to use
var templateid = 'foo';
var template = $templateCache.get(templateid);
return template;
}
return {
templateUrl: 'views/partials/template.html',
scope: {data: '='},
restrict: 'E',
link: function(scope, element) {
var template = getTemplate(scope.data);
element.html(template);
$compile(element.contents())(scope);
}
};
}]);
Using Linq to find the object you can do:
var obj = myList.FirstOrDefault(x => x.MyProperty == myValue);
if (obj != null) obj.OtherProperty = newValue;
But in this case you might want to save the List into a Dictionary and use this instead:
// ... define after getting the List/Enumerable/whatever
var dict = myList.ToDictionary(x => x.MyProperty);
// ... somewhere in code
MyObject found;
if (dict.TryGetValue(myValue, out found)) found.OtherProperty = newValue;
this solved my problem

From v0.20, melt
is a first order function, you can now use
df.melt(id_vars=["location", "name"],
var_name="Date",
value_name="Value")
location name Date Value
0 A "test" Jan-2010 12
1 B "foo" Jan-2010 18
2 A "test" Feb-2010 20
3 B "foo" Feb-2010 20
4 A "test" March-2010 30
5 B "foo" March-2010 25
OLD(ER) VERSIONS: <0.20
You can use pd.melt
to get most of the way there, and then sort:
>>> df
location name Jan-2010 Feb-2010 March-2010
0 A test 12 20 30
1 B foo 18 20 25
>>> df2 = pd.melt(df, id_vars=["location", "name"],
var_name="Date", value_name="Value")
>>> df2
location name Date Value
0 A test Jan-2010 12
1 B foo Jan-2010 18
2 A test Feb-2010 20
3 B foo Feb-2010 20
4 A test March-2010 30
5 B foo March-2010 25
>>> df2 = df2.sort(["location", "name"])
>>> df2
location name Date Value
0 A test Jan-2010 12
2 A test Feb-2010 20
4 A test March-2010 30
1 B foo Jan-2010 18
3 B foo Feb-2010 20
5 B foo March-2010 25
(Might want to throw in a .reset_index(drop=True)
, just to keep the output clean.)

The value you are setting in the timeout
attribute is the one of the correct ways to set the session timeout value.
The timeout
attribute specifies the number of minutes a session can be idle before it is abandoned. The default value for this attribute is 20.
By assigning a value of 1 to this attribute, you've set the session to be abandoned in 1 minute after its idle.
To test this, create a simple aspx page, and write this code in the Page_Load event,
Response.Write(Session.SessionID);
Open a browser and go to this page. A session id will be printed. Wait for a minute to pass, then hit refresh. The session id will change.
Now, if my guess is correct, you want to make your users log out as soon as the session times out. For doing this, you can rig up a login page which will verify the user credentials, and create a session variable like this -
Session["UserId"] = 1;
Now, you will have to perform a check on every page for this variable like this -
if(Session["UserId"] == null)
Response.Redirect("login.aspx");
This is a bare-bones example of how this will work.
But, for making your production quality secure apps, use Roles & Membership classes provided by ASP.NET. They provide Forms-based authentication which is much more reliabletha the normal Session-based authentication you are trying to use.
You can do this:
Change the package name manually in the manifest file. Click on your R.java class and the press F6 (Refactor->Move...). It will allow you to move the class to other package, and all references to that class will be updated.

You can use ternary operator for conditional statements in dart, It's use is simple
(condition) ? statement1 : statement2
if the condition
is true then the statement1
will be executed otherwise statement2
.
Taking a practical example
Center(child: condition ? Widget1() : Widget2())
Remember if you are going to use null
as Widget2
it is better to use SizedBox.shrink()
because some parent widgets will throw an exception after getting a null
child.
The git command that would be the closest from what you are looking for would by git archive
.
See backing up project which uses git: it will include in an archive all files (including submodules if you are using the git-archive-all
script)
You can then use that archive anywhere, giving you back only files, no .git
directory.
git archive --remote=<repository URL> | tar -t
If you need folders and files just from the first level:
git archive --remote=<repository URL> | tar -t --exclude="*/*"
To list only first-level folders of a remote repo:
git archive --remote=<repository URL> | tar -t --exclude="*/*" | grep "/"
Note: that does not work for GitHub (not supported)
So you would need to clone (shallow to quicken the clone step), and then archive locally:
git clone --depth=1 [email protected]:xxx/yyy.git
cd yyy
git archive --format=tar aTag -o aTag.tar
Another option would be to do a shallow clone (as mentioned below), but locating the .git folder elsewhere.
git --git-dir=/path/to/another/folder.git clone --depth=1 /url/to/repo
The repo folder would include only the file, without .git
.
Note: git --git-dir
is an option of the command git
, not git clone
.
Update with Git 2.14.X/2.15 (Q4 2017): it will make sure to avoid adding empty folders.
"
git archive
", especially when used with pathspec, stored an empty directory in its output, even though Git itself never does so.
This has been fixed.

archive
: don't add empty directories to archivesWhile git doesn't track empty directories,
git archive
can be tricked into putting some into archives.
While that is supported by the object database, it can't be represented in the index and thus it's unlikely to occur in the wild.As empty directories are not supported by git, they should also not be written into archives.
If an empty directory is really needed then it can be tracked and archived by placing an empty.gitignore
file in it.
I was just searching for something similar:
I want to sum every odd row column.
SUMIF
has TWO possible ranges, the range to sum from, and a range to consider criteria in.
SUMIF(B1:B1000,1,A1:A1000)
This function will consider if a cell in the B range is "=1", it will sum the corresponding A cell only if it is.
To get "=1" to return in the B range I put this in B:
=MOD(ROWNUM(B1),2)
Then auto fill down to get the modulus to fill, you could put and calculatable criteria here to get the SUMIF or SUMIFS conditions you need to loop through each cell.
Easier than ARRAY stuff and hides the back-end of loops!
There is no way to create an array of a predefined size without also supplying values for the elements of that array.
The best way to initialize an array like that is array_fill
. By far preferable over the various loop-and-insert solutions.
$my_array = array_fill(0, $size_of_the_array, $some_data);
Every position in the $my_array
will contain $some_data
.
The first zero in array_fill
just indicates the index from where the array needs to be filled with the value.

All byte code is 8-bit based. (That's why its called BYTE code) All the instructions are a multiple of 8-bits in size. We develop on 32-bit machines and run our servers with 64-bit JVM.
Could you give some detail of the problem you are facing? Then we might have a chance of helping you. Otherwise we would just be guessing what the problem is you are having.
Depending on what language you are programming in, you can use a function to replace double quotes with two double quotes.
For example in PHP that would be:
str_replace('"', '""', $string);
If you are trying to do that using SQL only, maybe REPLACE() is what you are looking for.
So your query would look something like this:
"UPDATE Table SET columnname = '" & REPLACE(@wstring, '"', '""') & "' where ... blah ... blah "
This is a slight variation that worked better for me.

I built a pretty simple format function that I call whenever I need a simple date formatted. It deals with formatting single digits to double digits when they're less than 10. It kicks out a date formatted as Sat Sep 29 2018 - 00:05:44
This function is used as part of a utils variable so it's called as:
let timestamp = utils._dateFormatter('your date string');
var utils = {
_dateFormatter: function(dateString) {
let d = new Date(dateString);
let hours = d.getHours();
let minutes = d.getMinutes();
let seconds = d.getSeconds();
d = d.toDateString();
if (hours < 10) {
hours = '0' + hours;
}
if (minutes < 10) {
minutes = '0' + minutes;
}
if (seconds < 10) {
seconds = '0' + seconds;
}
let formattedDate = d + ' - ' + hours + ':' + minutes + ':' + seconds;
return formattedDate;

I think you should check the following project at codeplex.com http://autoupdater.codeplex.com/
This sample application is developed in C# as a library with the project name “AutoUpdater”. The DLL “AutoUpdater” can be used in a C# Windows application(WinForm and WPF).
There are certain features about the AutoUpdater:
How to use?
In the program that you want to be auto updateable, you just need to call the AutoUpdate function in the Main procedure. The AutoUpdate function will check the version with the one read from a file located in a Web Site/FTP. If the program version is lower than the one read the program downloads the auto update program and launches it and the function returns True, which means that an auto update will run and the current program should be closed. The auto update program receives several parameters from the program to be updated and performs the auto update necessary and after that launches the updated system.

I just had a very similar issue with the added problem that I needed to create download links to files inside a ZIP file.
I first tried to create a temporary file, then provided a link to the temporary file, but I found that some browsers would just display the contents (a CSV Excel file) rather than offering to download. Eventually I found the solution by using a servlet. It works both on Tomcat and GlassFish, and I tried it on Internet Explorer 10 and Chrome.
The servlet takes as input a full path name to the ZIP file, and the name of the file inside the zip that should be downloaded.
Inside my JSP file I have a table displaying all the files inside the zip, with links that say: onclick='download?zip=<%=zip%>&csv=<%=csv%>'
The servlet code is in download.java:
package myServlet;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.zip.*;
import java.util.*;
// Extend HttpServlet class
public class download extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
PrintWriter out = response.getWriter(); // now we can write to the client
String filename = request.getParameter("csv");
String zipfile = request.getParameter("zip");
String aLine = "";
response.setContentType("application/x-download");
response.setHeader( "Content-Disposition", "attachment; filename=" + filename); // Force 'save-as'
ZipFile zip = new ZipFile(zipfile);
for (Enumeration e = zip.entries(); e.hasMoreElements();) {
ZipEntry entry = (ZipEntry) e.nextElement();
if(entry.toString().equals(filename)) {
InputStream is = zip.getInputStream(entry);
BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"), 65536);
while ((aLine = br.readLine()) != null) {
out.println(aLine);
}
is.close();
break;
}
}
}
}
To compile on Tomcat you need the classpath to include tomcat\lib\servlet-api.jar or on GlassFish: glassfish\lib\j2ee.jar
But either one will work on both. You also need to set your servlet in web.xml
.
The cause of this error can be traced from Illuminate\View\Compilers\Compiler.php
public function __construct(Filesystem $files, $cachePath)
{
if (! $cachePath) {
throw new InvalidArgumentException('Please provide a valid cache path.');
}
$this->files = $files;
$this->cachePath = $cachePath;
}
The constructor is invoked by BladeCompiler in Illuminate\View\ViewServiceProvider
/**
* Register the Blade engine implementation.
*
* @param \Illuminate\View\Engines\EngineResolver $resolver
* @return void
*/
public function registerBladeEngine($resolver)
{
// The Compiler engine requires an instance of the CompilerInterface, which in
// this case will be the Blade compiler, so we'll first create the compiler
// instance to pass into the engine so it can compile the views properly.
$this->app->singleton('blade.compiler', function () {
return new BladeCompiler(
$this->app['files'], $this->app['config']['view.compiled']
);
});
$resolver->register('blade', function () {
return new CompilerEngine($this->app['blade.compiler']);
});
}
So, tracing back further, the following code:
$this->app['config']['view.compiled']
is generally located in your /config/view.php, if you use the standard laravel structure.
<?php
return [

'compiled' => realpath(storage_path('framework/views')),
];
realpath(...) returns false, if the path does not exist. Thus, invoking
'Please provide a valid cache path.' error.
Therefore, to get rid of this error, what you can do is to ensure that
storage_path('framework/views')
or
/storage/framework/views
exists :)
The previous answer is pretty good, but I also wanted to mention that there is a fixed layout equivalent for grids, you just need to write minmax(0, 1fr)
instead of 1fr
as your track size.

I use this method in my css file
@font-face {
font-family: FontName1;
src: url("fontname1.eot"); /* IE */
src: local('FontName1'), url('fontname1.ttf') format('truetype'); /* others */
}
@font-face {
font-family: FontName2;
src: url("fontname1.eot"); /* IE */
src: local('FontName2'), url('fontname2.ttf') format('truetype'); /* others */
}
@font-face {
font-family: FontName3;
src: url("fontname1.eot"); /* IE */
src: local('FontName3'), url('fontname3.ttf') format('truetype'); /* others */
}
This is pretty simple here is an example
Add your command code here like:
if (cmd === `!dm`) {
let dUser =
message.guild.member(message.mentions.users.first()) ||
message.guild.members.get(args[0]);
if (!dUser) return message.channel.send("Can't find user!");
if (!message.member.hasPermission('ADMINISTRATOR'))
return message.reply("You can't you that command!");
let dMessage = args.join(' ').slice(22);
if (dMessage.length < 1) return message.reply('You must supply a message!');
dUser.send(`${dUser} A moderator from WP Coding Club sent you: ${dMessage}`);
message.author.send(
`${message.author} You have sent your message to ${dUser}`
);
}
JUnit5 adds the assertAll() method for this exact purpose.
assertAll( () -> foo() )
this worked for me:
1.make a standards compliant link:
<a href="tel:1500100900">
2.replace it when mobile browser is not detected, for skype:
$("a.phone")
.each(function()
{
this.href = this.href.replace(/^tel/,
"callto");
});
Selecting link to replace via class seems more efficient.
Of course it works only on anchors with .phone
class.
I have put it in function if( !isMobile() ) { ...
so it triggers only when detects desktop browser. But this one is problably obsolete...
function isMobile() {
return (
( navigator.userAgent.indexOf( "iPhone" ) > -1 ) ||
( navigator.userAgent.indexOf( "iPod" ) > -1 ) ||
( navigator.userAgent.indexOf( "iPad" ) > -1 ) ||
( navigator.userAgent.indexOf( "Android" ) > -1 ) ||
( navigator.userAgent.indexOf( "webOS" ) > -1 )
);
}
In pydev eclipse plugin, you may want to set the environment variable for DYLD. The path can be set as shown in
You can still unit test a void method by asserting that it had the appropriate side effect. In your method1
example, your unit test might look something like:
public void checkIfValidElementsWithDollarSign() {
checkIfValidElement("$",19);
assert ErrorFile.errorMessages.contains("There is a dollar sign in the specified parameter");
}
A few of the options are deprecated as of today. So watch out for those.
If you try <input onkeypress="blockSpecialCharacters(event)" />
, an IDE like WebStorm
will slash out event and tell you:
Deprecated symbol used, consults docs for better alternative
Then when you get to the JavaScript, console.log(e.keyCode)
will also give keyCode and say:
Deprecated symbol used, consults docs for better alternative
Anyways I did it using jQuery.
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.js"></script>
<input id="theInput" />
<script>
function blockSpecialCharacters(e) {
let key = e.key;
let keyCharCode = key.charCodeAt(0);
// 0-9
if(keyCharCode >= 48 && keyCharCode <= 57) {
return key;
}
// A-Z
if(keyCharCode >= 65 && keyCharCode <= 90) {
return key;
}
// a-z
if(keyCharCode >= 97 && keyCharCode <= 122) {
return key;
}
return false;
}
$('#theInput').keypress(function(e) {
blockSpecialCharacters(e);
});
</script>
Matches won't be highlighted whenever you do a search using /
:set nohlsearch
:noh
or :nohlsearch
(clears until n or N is pressed)
nnoremap <esc> :noh<return><esc>
Clear highlights on pressing \ (backslash)
nnoremap \ :noh<return>
Clear highlights on hitting ESC twice
nnoremap <esc><esc> :noh<return>
Here's another minimal way to do it in CSS that works even in older browsers that do not support :nth-child
and the like selectors: http://jsfiddle.net/3wZWt/.
HTML:
<table>
<tr>
<th>From</th>
<th>Subject</th>
<th>Date</th>
</tr>
<tr>
<td>Dmitriy</td>
<td>Learning CSS</td>
<td>7/5/2014</td>
</tr>
</table>
CSS:
table {
border-collapse: collapse;
width: 100%;
}
tr > * {
border: 1px solid #000;
}
tr > th + th {
width: 70%;
}
tr > th + th + th {
width: 15%;
}
If you don't want search engines to index certain files, you can use robots.txt to tell web spiders not to access certain parts of your website.
If you rely only on javascript, then some users who browse without it won't be able to click your links.
Yes, underscores may be used anywhere in an identifier. I believe the rules are: any of a-z, A-Z, _ in the first character and those +0-9 for the following characters.
Underscore prefixes are common in C code -- a single underscore means "private", and double underscores are usually reserved for use by the compiler.
There are a few other choices in case the Adobe ActiveX isn't what you're looking for (since Acrobat must be present on the user machine and you can't ship it yourself).
For creating the PDF preview, first have a look at some other discussions on the subject on StackOverflow:
In the last two I talk about a few things you can try:
You can get a commercial renderer (PDFViewForNet, PDFRasterizer.NET, ABCPDF, ActivePDF, XpdfRasterizer and others in the other answers...).
Most are fairly expensive though, especially if all you care about is making a simple preview/thumbnails.
In addition to Omar Shahine's code snippet, there is a CodeProject article that shows how to use the Adobe ActiveX, but it may be out of date, easily broken by new releases and its legality is murky (basically it's ok for internal use but you can't ship it and you can't use it on a server to produce images of PDF).
You could have a look at the source code for SumatraPDF, an OpenSource PDF viewer for windows.
There is also Poppler, a rendering engine that uses Xpdf as a rendering engine. All of these are great but they will require a fair amount of commitment to make make them work and interface with .Net and they tend to be be distributed under the GPL.
You may want to consider using GhostScript as an interpreter because rendering pages is a fairly simple process.
The drawback is that you will need to either re-package it to install it with your app, or make it a pre-requisite (or at least a part of your install process).
It's not a big challenge, and it's certainly easier than having to massage the other rendering engines into cooperating with .Net.
I did a small project that you will find on the Developer Express forums as an attachment.
Be careful of the license requirements for GhostScript through.
If you can't leave with that then commercial software is probably your only choice.
Try this one for current selection:
Sub A_SelectAllMakeTable2()
Dim tbl As ListObject
Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
tbl.TableStyle = "TableStyleMedium15"
End Sub
or equivalent of your macro (for Ctrl+Shift+End range selection):
Sub A_SelectAllMakeTable()
Dim tbl As ListObject
Dim rng As Range
Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
tbl.TableStyle = "TableStyleMedium15"
End Sub
For people who are using only Doctrine DBAL and not the Doctrine ORM, they will not be able to access the getQuery()
method because it doesn't exists. They need to do something like the following.
$qb = new QueryBuilder($conn);
$count = $qb->select("count(id)")->from($tableName)->execute()->fetchColumn(0);
[1] First Design your tableview cell in StoryBoard.
[2] Put below table view delegate method
//MARK: - Tableview Delegate Methods
func numberOfSectionsInTableView(tableView: UITableView) -> Int
{
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return <“Your Array”>
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat
{
var totalHeight : CGFloat = <cell name>.<label name>.frame.origin.y
totalHeight += UpdateRowHeight(<cell name>.<label name>, textToAdd: <your array>[indexPath.row])
return totalHeight
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
var cell : <cell name>! = tableView.dequeueReusableCellWithIdentifier(“<cell identifire>”, forIndexPath: indexPath) as! CCell_VideoCall
if(cell == nil)
{
cell = NSBundle.mainBundle().loadNibNamed("<cell identifire>", owner: self, options: nil)[0] as! <cell name>;
}
<cell name>.<label name>.text = <your array>[indexPath.row] as? String
return cell as <cell name>
}
//MARK: - Custom Methods
func UpdateRowHeight ( ViewToAdd : UILabel , textToAdd : AnyObject ) -> CGFloat{
var actualHeight : CGFloat = ViewToAdd.frame.size.height
if let strName : String? = (textToAdd as? String)
where !strName!.isEmpty
{
actualHeight = heightForView1(strName!, font: ViewToAdd.font, width: ViewToAdd.frame.size.width, DesignTimeHeight: actualHeight )
}
return actualHeight
}
You could try this:
$(".edgetoedge").children().removeClass("highlight");
you can use simple code its work for transaction
Fragment newFragment = new MainCategoryFragment();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.content_frame_NavButtom, newFragment);
ft.commit();
I believe this can be solved by adding a project reference to Microsoft.EntityFrameworkCore.SqlServer.Design
Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design
Microsoft.EntityFrameworkCore.SqlServer wasn't directly installed in my project, but the .Design package will install it anyway as a prerequisite.
I was also curious if I can measure the speed of my script with apache abs or a construct / destruct php measure script or a php extension.
the last two have failed for me: they are approximate. after which I thought to try "ab" and "abs".
the command "ab -k -c 350 -n 20000 example.com/" is beautiful because it's all easier!
but did anyone think to "localhost" on any apache server for example www.apachefriends.org?
you should create a folder such as "bench" in root where you have 2 files: test "bench.php" and reference "void.php".
<?php
for($i=1;$i<50000;$i++){
print ('qwertyuiopasdfghjklzxcvbnm1234567890');
}
?>
<?php
?>
"c:\xampp\apache\bin\abs.exe" -n 10000 http://localhost/bench/void.php
"c:\xampp\apache\bin\abs.exe" -n 10000 http://localhost/bench/bench.php
pause
Now if you pay attention closely ...
the void script isn't produce zero results !!! SO THE CONCLUSION IS: from the second result the first result should be decreased!!!
here i got :

Update for CXF 3.1.7
In my case I put the WSDL files in src/main/resources
and added this path to my Srouces in Eclipse (Right Click on Project-> Build Path -> Configure Build Path...-> Source[Tab] -> Add Folder).
Here is how my pom
file looks like and as can be seen there is NO wsdlLocation
option needed:
<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-codegen-plugin</artifactId>
<version>${cxf.version}</version>
<executions>
<execution>
<id>generate-sources</id>
<phase>generate-sources</phase>
<configuration>
<sourceRoot>${project.build.directory}/generated/cxf</sourceRoot>
<wsdlOptions>
<wsdlOption>
<wsdl>classpath:wsdl/FOO_SERVICE.wsdl</wsdl>
</wsdlOption>
</wsdlOptions>
</configuration>
<goals>
<goal>wsdl2java</goal>
</goals>
</execution>
</executions>
</plugin>
And here is the generated Service. As can be seen the URL is get from ClassLoader and not from the Absolute File-Path
@WebServiceClient(name = "EventService",
wsdlLocation = "classpath:wsdl/FOO_SERVICE.wsdl",
targetNamespace = "http://www.sas.com/xml/schema/sas-svcs/rtdm-1.1/wsdl/")
public class EventService extends Service {
public final static URL WSDL_LOCATION;
public final static QName SERVICE = new QName("http://www.sas.com/xml/schema/sas-svcs/rtdm-1.1/wsdl/", "EventService");
public final static QName EventPort = new QName("http://www.sas.com/xml/schema/sas-svcs/rtdm-1.1/wsdl/", "EventPort");
static {
URL url = EventService.class.getClassLoader().getResource("wsdl/FOO_SERVICE.wsdl");
if (url == null) {
java.util.logging.Logger.getLogger(EventService.class.getName())
.log(java.util.logging.Level.INFO,
"Can not initialize the default wsdl from {0}", "classpath:wsdl/FOO_SERVICE.wsdl");
}
WSDL_LOCATION = url;
}
This is not accurate ---> "...* pass array. arrays are passed by reference. i.e. if you pass array of integers, modified the array inside the method.
Every parameter type is passed by value in Java. Arrays are object, its object reference is passed by value.
This includes an array of primitives (int, double,..) and objects. The integer value is changed by the methodTwo() but it is still the same arr object reference, the methodTwo() cannot add an array element or delete an array element. methodTwo() cannot also, create a new array then set this new array to arr. If you really can pass an array by reference, you can replace that arr with a brand new array of integers.
Every object passed as parameter in Java is passed by value, no exceptions.
from tkinter import *
import os
root = Tk()
file = filedialog.askdirectory()
changed_dir = os.listdir(file)
print(changed_dir)
root.mainloop()
There are several options, including using the method you demonstrate, With, and using a variable.
My preference is option 4 below: Dim
a variable of type Worksheet
and store the worksheet and call the methods on the variable or pass it to functions, however any of the options work.
Sub Test()
Dim SheetName As String
Dim SearchText As String
Dim FoundRange As Range
SheetName = "test"
SearchText = "abc"
' 0. If you know the sheet is the ActiveSheet, you can use if directly.
Set FoundRange = ActiveSheet.UsedRange.Find(What:=SearchText)
' Since I usually have a lot of Subs/Functions, I don't use this method often.
' If I do, I store it in a variable to make it easy to change in the future or
' to pass to functions, e.g.: Set MySheet = ActiveSheet
' If your methods need to work with multiple worksheets at the same time, using
' ActiveSheet probably isn't a good idea and you should just specify the sheets.
' 1. Using Sheets or Worksheets (Least efficient if repeating or calling multiple times)
Set FoundRange = Sheets(SheetName).UsedRange.Find(What:=SearchText)
Set FoundRange = Worksheets(SheetName).UsedRange.Find(What:=SearchText)
' 2. Using Named Sheet, i.e. Sheet1 (if Worksheet is named "Sheet1"). The
' sheet names use the title/name of the worksheet, however the name must
' be a valid VBA identifier (no spaces or special characters. Use the Object
' Browser to find the sheet names if it isn't obvious. (More efficient than #1)
Set FoundRange = Sheet1.UsedRange.Find(What:=SearchText)
' 3. Using "With" (more efficient than #1)
With Sheets(SheetName)
Set FoundRange = .UsedRange.Find(What:=SearchText)
End With
' or possibly...
With Sheets(SheetName).UsedRange
Set FoundRange = .Find(What:=SearchText)
End With
' 4. Using Worksheet variable (more efficient than 1)
Dim MySheet As Worksheet
Set MySheet = Worksheets(SheetName)
Set FoundRange = MySheet.UsedRange.Find(What:=SearchText)
' Calling a Function/Sub
Test2 Sheets(SheetName) ' Option 1
Test2 Sheet1 ' Option 2
Test2 MySheet ' Option 4
End Sub
Sub Test2(TestSheet As Worksheet)
Dim RowIndex As Long
For RowIndex = 1 To TestSheet.UsedRange.Rows.Count
If TestSheet.Cells(RowIndex, 1).Value = "SomeValue" Then
' Do something
End If
Next RowIndex
End Sub

Dragging an object and placing in a different location is part of the standard of HTML5. All the objects can be draggable. But the Specifications of below web browser should be followed. API Chrome Internet Explorer Firefox Safari Opera Version 4.0 9.0 3.5 6.0 12.0
You can find example from below: https://www.w3schools.com/html/tryit.asp?filename=tryhtml5_draganddrop2
Sometimes this
can refer to another scope and refer to something else, for example suppose you want to call a constructor method inside a DOM event, in this case this
will refer to the DOM element not the created object.
HTML
<button id="button">Alert Name</button>
JS
var Person = function(name) {
this.name = name;
var that = this;
this.sayHi = function() {
alert(that.name);
};
};
var ahmad = new Person('Ahmad');
var element = document.getElementById('button');
element.addEventListener('click', ahmad.sayHi); // => Ahmad
The solution above will assing this
to that
then we can and access the name property inside the sayHi
method from that
, so this can be called without issues inside the DOM call.
Another solution is to assign an empty that
object and add properties and methods to it and then return it. But with this solution you lost the prototype
of the constructor.
var Person = function(name) {
var that = {};
that.name = name;
that.sayHi = function() {
alert(that.name);
};
return that;
};
you can use too:
val frases = arrayOf("texto01","texto02 ","anotherText","and ")
for example.
I'm afraid your posted example is not working, since X and Y aren't defined. So instead of pcolormesh
let's use imshow
:
import numpy as np
import matplotlib.pyplot as plt
H = np.array([[1, 2, 3, 4],
[5, 6, 7, 8],
[9, 10, 11, 12],
[13, 14, 15, 16]]) # added some commas and array creation code
fig = plt.figure(figsize=(6, 3.2))
ax = fig.add_subplot(111)
ax.set_title('colorMap')
plt.imshow(H)
ax.set_aspect('equal')
cax = fig.add_axes([0.12, 0.1, 0.78, 0.8])
cax.get_xaxis().set_visible(False)
cax.get_yaxis().set_visible(False)
cax.patch.set_alpha(0)
cax.set_frame_on(False)
plt.colorbar(orientation='vertical')
plt.show()
you can use console.log()
to print object
console.log(my_object_array);
in case you have big object and want to print some of its values then you can use this custom function to print array in console
this.print = function (data,bpoint=0) {
var c = 0;
for(var k=0; k<data.length; k++){
c++;
console.log(c+' '+data[k]);
if(k!=0 && bpoint === k)break;
}
}
usage
print(array); // to print entire obj array
or
print(array,50); // 50 value to print only
float RandomFloat(float min, float max)
{
float r = (float)rand() / (float)RAND_MAX;
return min + r * (max - min);
}
I couldn't get any of the previous answers to work (on macOS).
A combination worked for me -
IO.write "\e[H\e[2J\e[3J"
This clears the buffer and the screen.
Try this: .aspx page
<td>
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True"OnTextChanged="TextBox1_TextChanged"></asp:TextBox>
<asp:AutoCompleteExtender ServiceMethod="GetCompletionList" MinimumPrefixLength="1"
CompletionInterval="10" EnableCaching="false" CompletionSetCount="1" TargetControlID="TextBox1"
ID="AutoCompleteExtender1" runat="server" FirstRowSelected="false">
</asp:AutoCompleteExtender>
Now To auto populate from database :
public static List<string> GetCompletionList(string prefixText, int count)
{
return AutoFillProducts(prefixText);
}
private static List<string> AutoFillProducts(string prefixText)
{
using (SqlConnection con = new SqlConnection())
{
con.ConnectionString = ConfigurationManager.ConnectionStrings["Conn"].ConnectionString;
using (SqlCommand com = new SqlCommand())
{
com.CommandText = "select ProductName from ProdcutMaster where " + "ProductName like @Search + '%'";
com.Parameters.AddWithValue("@Search", prefixText);
com.Connection = con;
con.Open();
List<string> countryNames = new List<string>();
using (SqlDataReader sdr = com.ExecuteReader())
{
while (sdr.Read())
{
countryNames.Add(sdr["ProductName"].ToString());
}
}
con.Close();
return countryNames;
}
}
}
Now:create a stored Procedure that fetches the Product details depending on the selected product from the Auto Complete Text Box.
Create Procedure GetProductDet
(
@ProductName varchar(50)
)
as
begin
Select BrandName,warranty,Price from ProdcutMaster where ProductName=@ProductName
End
Create a function name to get product details ::
private void GetProductMasterDet(string ProductName)
{
connection();
com = new SqlCommand("GetProductDet", con);
com.CommandType = CommandType.StoredProcedure;
com.Parameters.AddWithValue("@ProductName", ProductName);
SqlDataAdapter da = new SqlDataAdapter(com);
DataSet ds=new DataSet();
da.Fill(ds);
DataTable dt = ds.Tables[0];
con.Close();
//Binding TextBox From dataTable
txtbrandName.Text =dt.Rows[0]["BrandName"].ToString();
txtwarranty.Text = dt.Rows[0]["warranty"].ToString();
txtPrice.Text = dt.Rows[0]["Price"].ToString();
}
Auto post back should be true
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>
Now, Just call this function
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
//calling method and Passing Values
GetProductMasterDet(TextBox1.Text);
}
include_once('../../../wp-config.php');
global $wpdb;
$password = wp_hash_password("your password");

Was looking for the solution of a similar problem. Thanks to the answer provided by Davlet and Cupcake I was able to solve my problem.
Posting this answer here since I think this is the intended question
So I guess generally the problem that people like me face is what to do when a repo is cloned by another user on a server and that user is no longer associated with the repo.
How to pull from the repo without using the credentials of the old user ?
You edit the .git/config file of your repo.
and change
url = https://<old-username>@github.com/abc/repo.git/

I tried the following three methods, my file size is 1M, and I got results:
I run the program several times it looks that BufferedReader is faster.

String line = fileScanner.nextLine();
//System.out.println(line);
}
}
long end = new Date().getTime();
long time = end - start;
System.out.println("Scanner Time Consumed => " + time);

Use sorted()
with a key
as follows -
>>> unsorted_list = [['a','b','c','5','d'],['e','f','g','3','h'],['i','j','k','4','m']]
>>> sorted(unsorted_list, key = lambda x: int(x[3]))
[['e', 'f', 'g', '3', 'h'], ['i', 'j', 'k', '4', 'm'], ['a', 'b', 'c', '5', 'd']]
The lambda
returns the fourth element of each of the inner lists and the sorted
function uses that to sort those list. This assumes that int(elem)
will not fail for the list.
Or use itemgetter
(As Ashwini's comment pointed out, this method would not work if you have string representations of the numbers, since they are bound to fail somewhere for 2+ digit numbers)
>>> from operator import itemgetter
>>> sorted(unsorted_list, key = itemgetter(3))
[['e', 'f', 'g', '3', 'h'], ['i', 'j', 'k', '4', 'm'], ['a', 'b', 'c', '5', 'd']]
The problem is in your playerMovement
method. You are creating the string name of your room variables (ID1
, ID2
, ID3
):
letsago = "ID" + str(self.dirDesc.values())
However, what you create is just a str
. It is not the variable. Plus, I do not think it is doing what you think its doing:
>>>str({'a':1}.values())
'dict_values([1])'
If you REALLY needed to find the variable this way, you could use the eval
function:
>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'
or the globals
function:
class Foo(object):
def __init__(self):
super(Foo, self).__init__()
def test(self, name):
print(globals()[name])
foo = Foo()
bar = 'Hello World!'
foo.text('bar')
However, instead I would strongly recommend you rethink you class(es). Your userInterface
class is essentially a Room
. It shouldn't handle player movement. This should be within another class, maybe GameManager
or something like that.
Try this function....it works...
$(function() {
var myOptions = {
zoom: 10,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),myOptions);
var latlng_pos=[];
var j=0;
$(".property_item").each(function(){
latlng_pos[j]=new google.maps.LatLng($(this).find(".latitude").val(),$(this).find(".longitude").val());
j++;
var marker = new google.maps.Marker({
position: new google.maps.LatLng($(this).find(".latitude").val(),$(this).find(".longitude").val()),
// position: new google.maps.LatLng(-35.397, 150.640),
map: map
});
}
);
// map: an instance of google.maps.Map object
// latlng: an array of google.maps.LatLng objects
var latlngbounds = new google.maps.LatLngBounds( );
for ( var i = 0; i < latlng_pos.length; i++ ) {
latlngbounds.extend( latlng_pos[ i ] );
}
map.fitBounds( latlngbounds );
});
I was having the same problem just now. I solved it by uninstalling the latest Connector/NET drivers (6.7.4) and then installed the older drivers (6.6.5) and it works.
I am using Visual Studio 2010. I uninstalled the latest ones because I figured they were somehow related to .NET4.5, which I'm not able to use.
Update #1:
Supposedly another way is to register the MySql Connector with various Visual Studio versions (2010/2012/2013/2015...) during installation: Go to Modify Product Features and select all the relevant Visual Studio versions.
Update #2 - Visual Studio 2019 Update:
When I installed MySQL Community with the ConnectorNET and VisualStudio Plugin options included - MySQL didn't show up as a data provider in Visual Studio.
The installer I used included the VS Plugin version 1.2.9, which had supposedly fixed installation issues from 1.2.8, but still didn't work for me...
The solution for me was to uninstall the Connector and the Visual Studio Plugin, download them as individual components, and then install them separately (not as part of the MySQLServer Installer). Install the Connector first, then VS plugin after.
I found the solution here, Thanks to @LambertHeenan.
NOTE about Visual Studio Express
The OP asks whether MySQL is supported with Visual Studio Express (which as far as I can tell has been renamed to Visual Studio Community). In the past MySQL officially didn't support Visual Studio Express, as per @Paul's answer below, but they do officially support Visual Studio Community 2017 and 2019, according to this page.
I would recomend to use an external source for large color palettes.
http://tools.medialab.sciences-po.fr/iwanthue/
has a service to compose any size of palette according to various parameters and
discusses the generic problem from a graphics designers perspective and gives lots of examples of usable palettes.
To comprise a palette from RGB values you just have to copy the values in a vector as in e.g.:
colors37 = c("#466791","#60bf37","#953ada","#4fbe6c","#ce49d3","#a7b43d","#5a51dc","#d49f36","#552095","#507f2d","#db37aa","#84b67c","#a06fda","#df462a","#5b83db","#c76c2d","#4f49a3","#82702d","#dd6bbb","#334c22","#d83979","#55baad","#dc4555","#62aad3","#8c3025","#417d61","#862977","#bba672","#403367","#da8a6d","#a79cd4","#71482c","#c689d0","#6b2940","#d593a7","#895c8b","#bd5975")
This answer is more like an addition and a slight modification to the answers above.
In some versions of Visual Studio (and possibly other compilers) there is a bug that is really annoying and doesn't make sense. So if you declare/define your swap
function like this:
friend void swap(A& first, A& second) {
std::swap(first.size, second.size);
std::swap(first.arr, second.arr);
}
... the compiler will yell at you when you call the swap
function:
This has something to do with a friend
function being called and this
object being passed as a parameter.
A way around this is to not use friend
keyword and redefine the swap
function:
void swap(A& other) {
std::swap(size, other.size);
std::swap(arr, other.arr);
}
This time, you can just call swap
and pass in other
, thus making the compiler happy:
After all, you don't need to use a friend
function to swap 2 objects. It makes just as much sense to make swap
a member function that has one other
object as a parameter.
You already have access to this
object, so passing it in as a parameter is technically redundant.
Your UITableViewDelegate
should implement tableView:heightForRowAtIndexPath:
Objective-C
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return [indexPath row] * 20;
}
Swift 5
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return indexPath.row * 20
}
You will probably want to use NSString
's sizeWithFont:constrainedToSize:lineBreakMode:
method to calculate your row height rather than just performing some silly math on the indexPath :)
In a nutshell Javascript Closures allow a function to access a variable that is declared in a lexical-parent function.
Let's see a more detailed explanation. To understand closures it is important to understand how JavaScript scopes variables.
Scopes
In JavaScript scopes are defined with functions. Every function defines a new scope.
Consider the following example;
function f()
{//begin of scope f
var foo='hello'; //foo is declared in scope f
for(var i=0;i<2;i++){//i is declared in scope f
//the for loop is not a function, therefore we are still in scope f
var bar = 'Am I accessible?';//bar is declared in scope f
console.log(foo);
}
console.log(i);
console.log(bar);
}//end of scope f
calling f prints
hello
hello
2
Am I Accessible?
Let's now consider the case we have a function g
defined within another function f
.
function f()
{//begin of scope f
function g()
{//being of scope g
/*...*/
}//end of scope g
/*...*/
}//end of scope f
We will call f
the lexical parent of g
.
As explained before we now have 2 scopes; the scope f
and the scope g
.
But one scope is "within" the other scope, so is the scope of the child function part of the scope of the parent function? What happens with the variables declared in the scope of the parent function; will I be able to access them from the scope of the child function? That's exactly where closures step in.
Closures
In JavaScript the function g
can not only access any variables declared in scope g
but also access any variables declared in the scope of the parent function f
.
Consider following;
function f()//lexical parent function
{//begin of scope f
var foo='hello'; //foo declared in scope f
function g()
{//being of scope g
var bar='bla'; //bar declared in scope g
console.log(foo);
}//end of scope g
g();
console.log(bar);
}//end of scope f
calling f prints
hello
undefined
Let's look at the line console.log(foo);
. At this point we are in scope g
and we try to access the variable foo
that is declared in scope f
. But as stated before we can access any variable declared in a lexical parent function which is the case here; g
is the lexical parent of f
. Therefore hello
is printed.
Let's now look at the line console.log(bar);
. At this point we are in scope f
and we try to access the variable bar
that is declared in scope g
. bar
is not declared in the current scope and the function g
is not the parent of f
, therefore bar
is undefined
Actually we can also access the variables declared in the scope of a lexical "grand parent" function. Therefore if there would be a function h
defined within the function g
function f()
{//begin of scope f
function g()
{//being of scope g
function h()
{//being of scope h
/*...*/
}//end of scope h
/*...*/
}//end of scope g
/*...*/
}//end of scope f
then h
would be able to access all the variables declared in the scope of function h
, g
, and f
. This is done with closures. In JavaScript closures allows us to access any variable declared in the lexical parent function, in the lexical grand parent function, in the lexical grand-grand parent function, etc.
This can be seen as a scope chain; scope of current function -> scope of lexical parent function -> scope of lexical grand parent function -> ...
until the last parent function that has no lexical parent.
The window object
Actually the chain doesn't stop at the last parent function. There is one more special scope; the global scope. Every variable not declared in a function is considered to be declared in the global scope. The global scope has two specialities;
window
object.Therefore there are exactly two ways of declaring a variable foo
in the global scope; either by not declaring it in a function or by setting the property foo
of the window object.
Both attempts uses closures
Now that you have read a more detailed explanation it may now be apparent that both solutions uses closures. But to be sure, let's make a proof.
Let's create a new Programming Language; JavaScript-No-Closure. As the name suggests, JavaScript-No-Closure is identical to JavaScript except it doesn't support Closures.
In other words;
var foo = 'hello';
function f(){console.log(foo)};
f();
//JavaScript-No-Closure prints undefined
//JavaSript prints hello
Alright, let's see what happens with the first solution with JavaScript-No-Closure;
for(var i = 0; i < 10; i++) {
(function(){
var i2 = i;
setTimeout(function(){
console.log(i2); //i2 is undefined in JavaScript-No-Closure
}, 1000)
})();
}
therefore this will print undefined
10 times in JavaScript-No-Closure.
Hence the first solution uses closure.
Let's look at the second solution;
for(var i = 0; i < 10; i++) {
setTimeout((function(i2){
return function() {
console.log(i2); //i2 is undefined in JavaScript-No-Closure
}
})(i), 1000);
}
therefore this will print undefined
10 times in JavaScript-No-Closure.
Both solutions uses closures.
Edit: It is assumed that these 3 code snippets are not defined in the global scope. Otherwise the variables foo
and i
would be bind to the window
object and therefore accessible through the window
object in both JavaScript and JavaScript-No-Closure.
Write a custom template filter:
from django.template.defaulttags import register
...
@register.filter
def get_item(dictionary, key):
return dictionary.get(key)
(I use .get
so that if the key is absent, it returns none. If you do dictionary[key]
it will raise a KeyError
then.)
usage:
{{ mydict|get_item:item.NAME }}
If there is someone interested in achieve the @Pedro Silva solution in JS, I just ported this same solution for it:
const getBase64Size = (base64) => {
let padding = base64.length
? getBase64Padding(base64)
: 0
return ((Math.ceil(base64.length / 4) * 3 ) - padding) / 1000
}
const getBase64Padding = (base64) => {
return endsWith(base64, '==')
? 2
: 1
}
const endsWith = (str, end) => {
let charsFromEnd = end.length
let extractedEnd = str.slice(-charsFromEnd)
return extractedEnd === end
}
For selections, you can also convert the selection using the "To spaces" function. I usually just use it via the ctrl-shift-A then find "To Spaces" from there.
Simply use FractionallySizedBox
, where widthFactor
& heightFactor
define the percentage of app/parent size.
FractionallySizedBox(
widthFactor: 0.8, //means 80% of app width
child: RaisedButton(
onPressed: () {},
child: Text(
"Your Text",
style: TextStyle(color: Colors.white),
),
color: Colors.red,
)),
you can also try with && for mandatory constion if both condtion are true than work
//div ng-repeat="(k,v) in items"
<div ng-if="(k == 'a' && k == 'b')">
<!-- SOME CONTENT -->
</div>
If you label the if statement you can use break.
breakme: if (condition) {
// Do stuff
if (condition2){
// do stuff
} else {
break breakme;
}
// Do more stuff
}
You can even label and break plain blocks.
breakme: {
// Do stuff
if (condition){
// do stuff
} else {
break breakme;
}
// Do more stuff
}
It's not a commonly used pattern though, so might confuse people and possibly won't be optimised by compliers. It might be better to use a function and return, or better arrange the conditions.
( function() {
// Do stuff
if ( condition1 ) {
// Do stuff
} else {
return;
}
// Do other stuff
}() );
The DELIMITER statement changes the standard delimiter which is semicolon ( ;) to another. The delimiter is changed from the semicolon( ;) to double-slashes //.
Why do we have to change the delimiter?
Because we want to pass the stored procedure, custom functions etc. to the server as a whole rather than letting mysql tool to interpret each statement at a time.
Use
export LD_LIBRARY_PATH="/path/to/library/"
in your .bashrc otherwise, it'll only be available to bash and not any programs you start.
Try -R/path/to/library/
flag when you're linking, it'll make the program look in that directory and you won't need to set any environment variables.
EDIT: Looks like -R
is Solaris only, and you're on Linux.
An alternate way would be to add the path to /etc/ld.so.conf
and run ldconfig
. Note that this is a global change that will apply to all dynamically linked binaries.
This was happening to me with Visual Studio 2015 and ReSharper Ultimate 10.0.2. I tried pretty much all the solutions written prior to this answer (apart from any reinstallations) and nothing worked.
I got it working again with a variety of the above steps in a very specific order:
C:\Users\YourUsername\AppData\Local\JetBrains\Transient\ReSharperPlatformVs14\v04
as mentioned in some other postsHopefully after the last step you can breathe a sigh of relief that you don't have to reinstall anything, I certainly did!
For put method we have:
const putMethod = {
method: 'PUT', // Method itself
headers: {
'Content-type': 'application/json; charset=UTF-8' // Indicates the content
},
body: JSON.stringify(someData) // We send data in JSON format
}
// make the HTTP put request using fetch api
fetch(url, putMethod)
.then(response => response.json())
.then(data => console.log(data)) // Manipulate the data retrieved back, if we want to do something with it
.catch(err => console.log(err)) // Do something with the error
Example for someData, we can have some input fields or whatever you need:
const someData = {
title: document.querySelector(TitleInput).value,
body: document.querySelector(BodyInput).value
}
And in our data base
will have this in json
format:
{
"posts": [
"id": 1,
"title": "Some Title", // what we typed in the title input field
"body": "Some Body", // what we typed in the body input field
]
}
For delete method we have:
const deleteMethod = {
method: 'DELETE', // Method itself
headers: {
'Content-type': 'application/json; charset=UTF-8' // Indicates the content
},
// No need to have body, because we don't send nothing to the server.
}
// Make the HTTP Delete call using fetch api
fetch(url, deleteMethod)
.then(response => response.json())
.then(data => console.log(data)) // Manipulate the data retrieved back, if we want to do something with it
.catch(err => console.log(err)) // Do something with the error
In the url we need to type the id of the of deletion: https://www.someapi/id
This is the easiest solution if you have multiple files and do not want to type in the names one by one:
qpdf --empty --pages *.pdf -- out.pdf
I think stash -p
is probably the choice you want, but just in case you run into other even more tricky things in the future, remember that:
Stash
is really just a very simple alternative to the only slightly more complex branch
sets. Stash is very useful for moving things around quickly, but you can accomplish more complex things with branches without that much more headache and work.
# git checkout -b tmpbranch
# git add the_file
# git commit -m "stashing the_file"
# git checkout master
go about and do what you want, and then later simply rebase
and/or merge
the tmpbranch. It really isn't that much extra work when you need to do more careful tracking than stash will allow.
In my case this error appeared when I asigned to both dynamic created controls (combobox), same created control from other class.
//dynamic created controls
ComboBox combobox1 = ManagerControls.myCombobox1;
...some events
ComboBox combobox2 = ManagerControl.myComboBox2;
...some events
.
//method in constructor
public static void InitializeDynamicControls()
{
ComboBox cb = new ComboBox();
cb.Background = new SolidColorBrush(Colors.Blue);
...
cb.Width = 100;
cb.Text = "Select window";
ManagerControls.myCombobox1 = cb;
ManagerControls.myComboBox2 = cb; // <-- error here
}
Solution: create another ComboBox cb2
and assign it to ManagerControls.myComboBox2
.
I hope I helped someone.

My challenge to readers: Can you make this more efficient? What about using recursion?
I know this question has been answered, but just to point out what timeit
has to say about the solutions efficiency. Using these parameters:
size = 30
s = [str(random.randint(0, 9)) for i in range(size)] + (size/3) * ['-']
random.shuffle(s)
s = ''.join(['+'] + s)
timec = 1000
That is the "phone number" has 30 digits, 1 plus sing and 10 '-'. I've tested these approaches:
def justdigits(s):
justdigitsres = ""
for char in s:
if char.isdigit():
justdigitsres += str(char)
return justdigitsres
re_compiled = re.compile(r'\D')
print('Filter: %ss' % timeit.Timer(lambda : ''.join(filter(str.isdigit, s))).timeit(timec))
print('GE: %ss' % timeit.Timer(lambda : ''.join(n for n in s if n.isdigit())).timeit(timec))
print('LC: %ss' % timeit.Timer(lambda : ''.join([n for n in s if n.isdigit()])).timeit(timec))
print('For loop: %ss' % timeit.Timer(lambda : justdigits(s)).timeit(timec))
print('RE: %ss' % timeit.Timer(lambda : re.sub(r'\D', '', s)).timeit(timec))
print('REC: %ss' % timeit.Timer(lambda : re_compiled.sub('', s)).timeit(timec))
print('Translate: %ss' % timeit.Timer(lambda : s.translate(None, '+-')).timeit(timec))
And came out with these results:
Filter: 0.0145790576935s
GE: 0.0185861587524s

Apparently GEs and LCs are still slower than a regex or a compiled regex. And apparently my CPython 2.6.6 didn't optimize the string addition that much. translate
appears to be the fastest (which is expected as the problem is stated as "ignore these two symbols", rather than "get these numbers" and I believe is quite low-level).

to your toolbar xml file.
In an application I was developing I ran into what appeared to be a POST limit of about 2KB. It turned out to be that I was accidentally encoding the parameters into the URL instead of passing them in the body. So if you're running into a problem there, there is definitely a very small limit on the size of POST data you can send encoded into the URL.
Use this
<div *ngFor="let talk of talks>
{{talk.title}}
{{talk.speaker}}
<p>{{talk.description}}
</div>
You need to specify variable to iterate over an array of an object
I found out why this happening.
After looking at my settings on my wamp, i did not check http headers, since activated this, it now works.
Thank you everyone for trying to solve this. :)
Pickle serializes a single object at a time, and reads back a single object - the pickled data is recorded in sequence on the file.
If you simply do pickle.load
you should be reading the first object serialized into the file (not the last one as you've written).
After unserializing the first object, the file-pointer is at the beggining
of the next object - if you simply call pickle.load
again, it will read that next object - do that until the end of the file.
objects = []
with (open("myfile", "rb")) as openfile:
while True:
try:
objects.append(pickle.load(openfile))
except EOFError:
break
Try using jQuery.parseJSON when you get the data back.
type: "POST",
dataType: "json",
url: url,
data: { get_member: id },
success: function(data) {
response = jQuery.parseJSON(data);
$("input[ name = type ]:eq(" + response.type + " )")
.attr("checked", "checked");
$("input[ name = name ]").val( response.name);
$("input[ name = fname ]").val( response.fname);
$("input[ name = lname ]").val( response.lname);
$("input[ name = email ]").val( response.email);
$("input[ name = phone ]").val( response.phone);
$("input[ name = website ]").val( response.website);
$("#admin_member_img")
.attr("src", "images/member_images/" + response.image);
},
error: function(error) {
alert(error);
}
use zzz instead of TZD
Example:
DateTime.Now.ToString("yyyy-MM-ddThh:mm:sszzz");
Response:
2011-08-09T11:50:00:02+02:00
You'll have to create a custom object for that. Your custom object will contain two values:
Not sure if there already is a CLR-provided data type that has that, but at least the TimeZone component is already available.
You can query the all_tab_columns
view in the database.
SELECT table_name, column_name, data_type, data_length FROM all_tab_columns where table_name = 'CUSTOMER'
Building on Chad's answer, you also want to add that function to the onload event to ensure it is resized when the page loads as well.
jQuery.event.add(window, "load", resizeFrame);
jQuery.event.add(window, "resize", resizeFrame);
function resizeFrame()
{
var h = $(window).height();
var w = $(window).width();
$("#elementToResize").css('height',(h < 768 || w < 1024) ? 500 : 400);
}
You can try out baboonstack, which includes redis and also a node.js and mongoDB version manager. And it's cross platform.
Don't know the nature of your app, but I have seen this error manifested multiple times because of a connection pool leak, so that would be worth checking out. On Linux, socket connections consume file descriptors as well as file system files. Just a thought.
Other cases
io.of('/chat').on('connection', function (socket) {
//sending to all clients in 'room' and you
io.of('/chat').in('room').emit('message', "data");
};
On a freshly installed laravel 8, in the App/Providers/RouteServices.php
* The path to the "home" route for your application.
*
* This is used by Laravel authentication to redirect users after login.
*
* @var string
*/
public const HOME = '/home';
/**
* The controller namespace for the application.
*
* When present, controller route declarations will automatically be prefixed with this namespace.
*
* @var string|null
*/
// protected $namespace = 'App\\Http\\Controllers';
uncomment the
protected $namespace = 'App\Http\Controllers';
that should help you run laravel the old fashioned way.
Incase you are upgrading from lower versions of laravel to 8 then you might have to implicitly add the
protected $namespace = 'App\Http\Controllers';
in the RouteServices.php file for it to function the old way.
If you don't mind using NumPy, then:
In [319]: real = np.array([1234.5678])
In [327]: integ, deci = int(np.floor(real)), np.asscalar(real % 1)
In [328]: integ, deci
Out[328]: (1234, 0.5678000000000338)
This script will find files having a modification date of two minutes before and after the given date (and you can change the values in the conditions as per your requirement)
PATH_SRC="/home/celvas/Documents/Imp_Task/"
PATH_DST="/home/celvas/Downloads/zeeshan/"
cd $PATH_SRC
TODAY=$(date -d "$(date +%F)" +%s)
TODAY_TIME=$(date -d "$(date +%T)" +%s)
for f in `ls`;
do
# echo "File -> $f"
MOD_DATE=$(stat -c %y "$f")
MOD_DATE=${MOD_DATE% *}
# echo MOD_DATE: $MOD_DATE
MOD_DATE1=$(date -d "$MOD_DATE" +%s)
# echo MOD_DATE: $MOD_DATE
DIFF_IN_DATE=$[ $MOD_DATE1 - $TODAY ]
DIFF_IN_DATE1=$[ $MOD_DATE1 - $TODAY_TIME ]
#echo DIFF: $DIFF_IN_DATE
#echo DIFF1: $DIFF_IN_DATE1
if [[ ($DIFF_IN_DATE -ge -120) && ($DIFF_IN_DATE1 -le 120) && (DIFF_IN_DATE1 -ge -120) ]]
then
echo File lies in Next Hour = $f
echo MOD_DATE: $MOD_DATE
#mv $PATH_SRC/$f $PATH_DST/$f
fi
done
For example you want files having modification date before the given date only, you may change 120
to 0
in $DIFF_IN_DATE
parameter discarding the conditions of $DIFF_IN_DATE1
parameter.
Similarly if you want files having modification date 1 hour before and after given date,
just replace 120
by 3600
in if CONDITION
.

mysqldump
will backup by default all the triggers but NOT the stored procedures/functions. There are 2 mysqldump parameters that control this behavior:
--routines
– FALSE by default--triggers
– TRUE by defaultso in mysqldump
command , add --routines
like :
mysqldump <other mysqldump options> --routines > outputfile.sql
Using plyr
package:
library(plyr)
count(mydf$V1)
It will return you a frequency of each value.
java [ options ] -jar file.jar [ argument ... ]
and
... Non-option arguments after the class name or JAR file name are passed to the main function...
Maybe you have to put the arguments in single quotes.
If you are using Swift, this is how you do it

In Apache 2.4, the authorization configuration syntax has changed, and the Order
, Deny
or Allow
directives should no longer be used.
The new way to do this would be:
<VirtualHost *:8080>
<Location />
Require ip 192.168.1.0
</Location>
...
</VirtualHost>
Further examples using the new syntax can be found in the Apache documentation: Upgrading to 2.4 from 2.2
You can avoid compiler warning with workarounds like this one:
List<?> resultRaw = query.list();
List<MyObj> result = new ArrayList<MyObj>(resultRaw.size());
for (Object o : resultRaw) {
result.add((MyObj) o);
}
But there are some issues with this code:
And the difference is only cosmetic, so using such workarounds is - in my opinion - pointless.
You have to live with these warnings or suppress them.

heres a step by step procedure (assuming you've already installed python):
open terminal (Run as Administrator) and type in the command line:
C:/> @powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin
it will take some time to get chocolatey installed on your machine. sit back n relax...
now install pip. type in terminal cinst easy.install pip
now type in terminal: pip install flask
YOU'RE DONE !!! Tested on Win 8.1 with Python 2.7
Game marketing is a commercial process; publishers want quantifiable low-risk returns on their investment. As a consequence, the focus is usually on technology gimmicks (with exceptions) that consumers will buy to produce reliable return - these tend to be superficial visual effects such as lens glare or higher resolution. These effects are reliable because they simply use increases in processing power - they exploit the hardware/Moore's law increases. this implies using C/C++ - java is usually too abstracted from the hardware to exploit these benefits.
You can use Excel's Index
function:
=INDEX(Age, 5)
The answers that state that your kernel is still executing the code in the cell are correct. You can see that by the small circle in the top right. If it is filled with a black/grey color, then it means it is still running.
I just want to add that I experienced a problem in JupyterHub where the code in the cell would just not execute. I stopped and restarted the kernel, shutdown and reloaded the notebook, but it still did not run.
What worked for me was literally copy pasting the same code to a new cell and deleting the old one. It then ran from the new cell.
Here it is:
function call_func(input) {
var evaled = eval('(' + input + ')');
var newDiv = document.createElement('div');
var id = evaled.id;
var name = evaled.Student_name;
var dob = evaled.student_dob;
var html = '<b>ID:</b>';
html += '<a href="/learningyii/index.php?r=student/view& id=' + id + '">' + id + '</a>';
html += '<br/>';
html += '<b>Student Name:</b>';
html += name;
html += '<br/>';
html += '<b>Student DOB:</b>';
html += dob;
html += '<br/>';
newDiv.innerHTML = html;
newDiv.setAttribute('class', 'view');
$('#StudentGridViewId').find('.items').prepend(newDiv);
};
why not just declare that function inside the cshtml file?

Creating firewall rules
Please review the firewall rule components [1] if you are unfamiliar with firewall rules in GCP. Firewall rules are defined at the network level, and only apply to the network where they are created; however, the name you choose for each of them must be unique to the project.
For Cloud Console:
Specify the Targets of the rule.
For an ingress rule, specify the Source filter:
For an egress rule, specify the Destination filter:
Define the Protocols and ports to which the rule will apply:
Select Allow all or Deny all, depending on the action, to have the rule apply to all protocols and ports.
Define specific protocols and ports:
(Optional) You can create the firewall rule but not enforce it by setting its enforcement state to disabled. Click Disable rule, then select Disabled.
(Optional) You can enable firewall rules logging:
Click Create.

A Find/Replace solution:

Replace with: //single space
In addition to the answer of Trevor Johns, you can use this as follows:
TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.getDeviceId();
And you should add the following permission into your Manifest.xml file:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
In emulator, you'll probably get a like a "00000..." value. getDeviceId() returns NULL if device ID is not available.
I don't know if I can bump this thread, but I figured out a quick fix for the visual bug that happens when the open class is removed too fast. Basically, all there is to it is to add an OnComplete function inside the slideUp event and reset all active classes and attributes. Goes something like this:
Here is the result: Bootply example
Javascript/Jquery:
$(function(){
// ADD SLIDEDOWN ANIMATION TO DROPDOWN //
$('.dropdown').on('show.bs.dropdown', function(e){
$(this).find('.dropdown-menu').first().stop(true, true).slideDown();
});
// ADD SLIDEUP ANIMATION TO DROPDOWN //
$('.dropdown').on('hide.bs.dropdown', function(e){
e.preventDefault();
$(this).find('.dropdown-menu').first().stop(true, true).slideUp(400, function(){
//On Complete, we reset all active dropdown classes and attributes
//This fixes the visual bug associated with the open class being removed too fast
$('.dropdown').removeClass('show');
$('.dropdown-menu').removeClass('show');
$('.dropdown').find('.dropdown-toggle').attr('aria-expanded','false');
});
});
});
Earlier,I was facing problem in using jquery with React js,so I did following steps to make it working-
npm install jquery --save
Then, import $ from "jquery";
Actually you want to find whether the event is triggered by user or program , and its obvious that event will trigger while initialization.
The knockout approach of adding subscription
won't help in all cases, why because in most of the model will be implemented like this
(actual KO initilization)
(logical init like load JSON , get data etc)
The actual step that we want to capture is changes in 3, but in second step subscription
will get call ,
So a better way is to add to event change like
<select data-bind="value: level, event:{ change: $parent.permissionChanged}">
and detected the event in permissionChanged
function
this.permissionChanged = function (obj, event) {
if (event.originalEvent) { //user changed
} else { // program changed
}
}
Use OnCommand event of imagebutton. Within it do
<asp:Button id="Button1" Text="Click" CommandName="Something" CommandArgument="your command arg" OnCommand="CommandBtn_Click" runat="server"/>
Code-behind:
void CommandBtn_Click(Object sender, CommandEventArgs e)
{
switch(e.CommandName)
{
case "Something":
// Do your code
break;
default:
break;
}
}
A lightweight solution with Check constraint:
CREATE TABLE example (
discriminator INTEGER DEFAULT 0 NOT NULL CHECK (discriminator = 0)
);
Here is my class, works like a charm :
public static class IniFileManager
{
[DllImport("kernel32")]
private static extern long WritePrivateProfileString(string section,
string key, string val, string filePath);
[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section,
string key, string def, StringBuilder retVal,
int size, string filePath);
[DllImport("kernel32.dll")]
private static extern int GetPrivateProfileSection(string lpAppName,
byte[] lpszReturnBuffer, int nSize, string lpFileName);
/// <summary>
/// Write Data to the INI File
/// </summary>
/// <PARAM name="Section"></PARAM>
/// Section name
/// <PARAM name="Key"></PARAM>
/// Key Name
/// <PARAM name="Value"></PARAM>
/// Value Name
public static void IniWriteValue(string sPath,string Section, string Key, string Value)
{
WritePrivateProfileString(Section, Key, Value, sPath);
}
/// <summary>
/// Read Data Value From the Ini File
/// </summary>
/// <PARAM name="Section"></PARAM>
/// <PARAM name="Key"></PARAM>
/// <PARAM name="Path"></PARAM>
/// <returns></returns>
public static string IniReadValue(string sPath,string Section, string Key)
{
StringBuilder temp = new StringBuilder(255);
int i = GetPrivateProfileString(Section, Key, "", temp,
255, sPath);
return temp.ToString();
}
}
The use is obviouse since its a static class, just call IniFileManager.IniWriteValue for readsing a section or IniFileManager.IniReadValue for reading a section.
NGINX itself may not be the root cause.
IF "minimum ports per VM instance" set on the NAT Gateway -- which stand between your NGINX instance & the proxy_pass
destination -- is too small for the number of concurrent requests, it has to be increased.
Solution: Increase the available number of ports per VM on NAT Gateway.
Context In my case, on Google Cloud, a reverse proxy NGINX was placed inside a subnet, with a NAT Gateway. The NGINX instance was redirecting requests to a domain associated with our backend API (upstream) through the NAT Gateway.
This documentation from GCP will help you understand how NAT is relevant to the NGINX 504 timeout.
Staying MVVM, I think using either Behaviors from the Blend SDK (System.Windows.Interactivity) or a custom interaction request from Prism could work really well for this sort of situation.
If going the Behavior route, here's the general idea:
public class CloseWindowBehavior : Behavior<Window>
{
public bool CloseTrigger
{
get { return (bool)GetValue(CloseTriggerProperty); }
set { SetValue(CloseTriggerProperty, value); }
}
public static readonly DependencyProperty CloseTriggerProperty =
DependencyProperty.Register("CloseTrigger", typeof(bool), typeof(CloseWindowBehavior), new PropertyMetadata(false, OnCloseTriggerChanged));
private static void OnCloseTriggerChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var behavior = d as CloseWindowBehavior;
if (behavior != null)
{
behavior.OnCloseTriggerChanged();
}
}
private void OnCloseTriggerChanged()
{
// when closetrigger is true, close the window
if (this.CloseTrigger)
{
this.AssociatedObject.Close();
}
}
}
Then in your window, you would just bind the CloseTrigger to a boolean value that would be set when you wanted the window to close.
<Window x:Class="TestApp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
xmlns:local="clr-namespace:TestApp"
Title="MainWindow" Height="350" Width="525">
<i:Interaction.Behaviors>
<local:CloseWindowBehavior CloseTrigger="{Binding CloseTrigger}" />
</i:Interaction.Behaviors>
<Grid>
</Grid>
</Window>
Finally, your DataContext/ViewModel would have a property that you'd set when you wanted the window to close like this:
public class MainWindowViewModel : INotifyPropertyChanged
{
private bool closeTrigger;
/// <summary>
/// Gets or Sets if the main window should be closed
/// </summary>
public bool CloseTrigger
{
get { return this.closeTrigger; }
set
{
this.closeTrigger = value;
RaisePropertyChanged(nameof(CloseTrigger));
}
}
public MainWindowViewModel()
{
// just setting for example, close the window
CloseTrigger = true;
}

I believe it stems from the Python creed that "explicit is better than implicit".
You should create a StreamReader
around the stream, then call ReadToEnd
.
You should consider calling WebClient.DownloadString
instead.
You can directly set the content type like below:
res.writeHead(200, {'Content-Type': 'text/plain'});
For reference go through the nodejs Docs link.
It appears that you are extracting you certificate from the PKCS #12 key store and creating a new Java key store (with type "JKS"). You don't strictly have to provide a trust store password (although using one allows you to test the integrity of your root certificates).
So, try your program with only the following SSL properties set. The list shown in your question is over-specified and may be causing problems.
System.setProperty("javax.net.ssl.trustStore", "myTrustStore");
System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
Also, using the PKCS #12 file directly as the trust store should work, as long as the CA certificate is detected as a "trusted" entry. But in that case, you'll have to specify the javax.net.ssl.trustStoreType
property as "PKCS12"
too.
Try with these properties only. If you get the same error, I suspect your problem is not the key store. If it still occurs, post more of the stack trace in your question to narrow the problem down.
The new error, "the trustAnchors parameter must be non-empty," could be due to setting the javax.net.ssl.trustStore
property to a file that doesn't exist; if the file cannot be opened, an empty key store created, which would lead to this error.
Also, their "device dashboard" stats at:
http://developer.android.com/about/dashboards/index.html#Screens
can be pretty helpful. They are current and derived from Android Market visits.
Prevent saving changes that require table re-creation
Five swift clicks
- Tools
- Options
- Designers
- Prevent saving changes that require table re-creation
- OK.
After saving, repeat the proceudure to re-tick the box. This safe-guards against accidental data loss.
Further explanation
By default SQL Server Management Studio prevents the dropping of tables, because when a table is dropped its data contents are lost.*
When altering a column's datatype in the table Design view, when saving the changes the database drops the table internally and then re-creates a new one.
*Your specific circumstances will not pose a consequence since your table is empty. I provide this explanation entirely to improve your understanding of the procedure.
You are trying to delete a row that is referenced by another row (possibly in another table).
You need to delete that row first (or at least re-set its foreign key to something else), otherwise you’d end up with a row that references a non-existing row. The database forbids that.
In my case, I reinstalled Python. It solved the problem.
brew reinstall python
Please note that in the jQuery universe this must be implemented differently as of version 1.8. The following release note is from the jQuery blog:
.data(“events”): jQuery stores its event-related data in a data object named (wait for it) events on each element. This is an internal data structure so in 1.8 this will be removed from the user data name space so it won’t conflict with items of the same name. jQuery’s event data can still be accessed via jQuery._data(element, "events")
We do have complete control of the order in which the handlers will execute in the jQuery universe. Ricoo points this out above. Doesn't look like his answer earned him a lot of love, but this technique is very handy. Consider, for example, any time you need to execute your own handler prior to some handler in a library widget, or you need to have the power to cancel the call to the widget's handler conditionally:
$("button").click(function(e){
if(bSomeConditional)
e.stopImmediatePropagation();//Don't execute the widget's handler
}).each(function () {
var aClickListeners = $._data(this, "events").click;
aClickListeners.reverse();
});
Perhaps an example will help:
git rm --cached asd
git commit -m "the file asd is gone from the repository"
versus
git reset HEAD -- asd
git commit -m "the file asd remains in the repository"
Note that if you haven't changed anything else, the second commit won't actually do anything.
This works, but does not animate.
$('.btn-navbar').addClass('collapsed');
$('.nav-collapse').removeClass('in').css('height', '0');
You can use boolean indexing
:
df = pd.DataFrame({'Sales':[10,20,30,40,50], 'A':[3,4,7,6,1]})
print (df)
A Sales
0 3 10
1 4 20
2 7 30
3 6 40
4 1 50
s = 30
df1 = df[df['Sales'] >= s]
print (df1)
A Sales
2 7 30
3 6 40
4 1 50
df2 = df[df['Sales'] < s]
print (df2)
A Sales
0 3 10
1 4 20
It's also possible to invert mask
by ~
:
mask = df['Sales'] >= s
df1 = df[mask]
df2 = df[~mask]
print (df1)
A Sales
2 7 30
3 6 40
4 1 50
print (df2)
A Sales
0 3 10
1 4 20
print (mask)
0 False
1 False
2 True
3 True
4 True
Name: Sales, dtype: bool
print (~mask)
0 True
1 True
2 False
3 False
4 False
Name: Sales, dtype: bool
Java doesn't have direct equivalent of C# language feature called async/await, however there's a different approach to the problem that async/await tries to solve. It's called project Loom, which will provide virtual threads for high-throughput concurrency. It will be available in some future version of OpenJDK.
This approach also solves "colored function problem" that async/await has.
Similar feature can be also found in Golang (goroutines).
The other answers are not incorrect. However, now there are more options for opening files. For example, if you want the app to have long term, permanent acess to a file, you can use ACTION_OPEN_DOCUMENT
instead. Refer to the official documentation: Open files using storage access framework. Also refer to this answer.
System properties are set on the Java command line using the -Dpropertyname=value
syntax. They can also be added at runtime
using System.setProperty(String key, String value)
or via the various
System.getProperties().load()
methods.
To get a specific system property you can use System.getProperty(String key)
or System.getProperty(String key, String def)
.
Environment variables are set in the OS, e.g. in Linux export HOME=/Users/myusername
or on Windows SET WINDIR=C:\Windows
etc,
and, unlike properties, may not be set at runtime.
To get a specific environment variable you can use System.getenv(String name)
.
Here's what works for me. I'm sure it can be improved, so feel free to make suggestions or edit to make it better.
const string WEBSERVICE_URL = "http://localhost/projectname/ServiceName.svc/ServiceMethod";
//This string is untested, but I think it's ok.
string jsonData = "{ \"key1\" : \"value1\", \"key2\":\"value2\" }";
try
{
var webRequest = System.Net.WebRequest.Create(WEBSERVICE_URL);
if (webRequest != null)
{
webRequest.Method = "POST";
webRequest.Timeout = 20000;
webRequest.ContentType = "application/json";
using (System.IO.Stream s = webRequest.GetRequestStream())
{
using (System.IO.StreamWriter sw = new System.IO.StreamWriter(s))
sw.Write(jsonData);
}
using (System.IO.Stream s = webRequest.GetResponse().GetResponseStream())
{
using (System.IO.StreamReader sr = new System.IO.StreamReader(s))
{
var jsonResponse = sr.ReadToEnd();
System.Diagnostics.Debug.WriteLine(String.Format("Response: {0}", jsonResponse));
}
}
}
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex.ToString());
}
I wrote with parameters that are predefined
They are not "predefined" logically, somewhere inside your code. But as arguments of SP they have no default values and are required. To avoid passing those params explicitly you have to define default values in SP definition:
Alter Procedure [Test]
@StartDate AS varchar(6) = NULL,
@EndDate AS varchar(6) = NULL
AS
...
NULLs or empty strings or something more sensible - up to you. It does not matter since you are overwriting values of those arguments in the first lines of SP.
Now you can call it without passing any arguments e.g.
exec dbo.TEST
Here's my attempt with Javascript and CSS3 animation So the HTML:
<div id="handle">Fade</div>
<div id="slideSource">Whatever you want images or text here</div>
The CSS3 with transitions:
div#slideSource {
opacity:1;
-webkit-transition: opacity 3s;
-moz-transition: opacity 3s;
transition: opacity 3s;
}
div#slideSource.fade {
opacity:0;
}
The Javascript part. Check if the className exists, if it does then add the class and transitions.
document.getElementById('handle').onclick = function(){
if(slideSource.className){
document.getElementById('slideSource').className = '';
} else {
document.getElementById('slideSource').className = 'fade';
}
}
Just click and it will fade in and out. I would recommend using JQuery as Itai Sagi mentioned. I left out Opera and MS, so I would recommend using prefixr to add that in the css. This is my first time posting on stackoverflow but it should work fine.
You can use find() :
$('#my_id').find('my_class');
Or maybe:
$('#my_id').find('span');
Both methods will word for what you want
To amend kris' answer, starting with Git 2.20 (Q4 2018), the proper command for git mergetool
will be
git config --global merge.guitool kdiff3
That is because "git mergetool
" learned to take the "--[no-]gui
" option, just like
"git difftool
" does.
See commit c217b93, commit 57ba181, commit 063f2bd (24 Oct 2018) by Denton Liu (Denton-L
).
(Merged by Junio C Hamano -- gitster
-- in commit 87c15d1, 30 Oct 2018)
mergetool
: accept-g/--[no-]gui
as argumentsIn line with how
difftool
accepts a-g/--[no-]gui
option, makemergetool
accept the same option in order to use themerge.guitool
variable to find the default mergetool instead ofmerge.tool
.

function getByClass (className, parent) {
parent || (parent=document);
var descendants=parent.getElementsByTagName('*'), i=-1, e, result=[];
while (e=descendants[++i]) {
((' '+(e['class']||e.className)+' ').indexOf(' '+className+' ') > -1) && result.push(e);
}
return result;
}
You should be able to use it like this:
function replaceInClass (className, content) {
var nodes = getByClass(className), i=-1, node;
while (node=nodes[++i]) node.innerHTML = content;
}
You're mixing the parts together instead of separating them cleanly.
printf '\e[1;34m%-6s\e[m' "This is text"
Basically, put the fixed stuff in the format and the variable stuff in the parameters.
In CurrentGame
component you need to change initial state because you are trying use loop for participants
but this property is undefined
that's why you get error.,
getInitialState: function(){
return {
data: {
participants: []
}
};
},
also, as player
in .map
is Object
you should get properties from it
this.props.data.participants.map(function(player) {
return <li key={player.championId}>{player.summonerName}</li>
// -------------------^^^^^^^^^^^---------^^^^^^^^^^^^^^

Okay, of course the question has been answered, but no-one seems to notice the third line of your code. It continuosly bugged me.
<?php
mysqli_connect("localhost","root","","web_table");
mysql_select_db("web_table") or die(mysql_error());
for some reason, you made a mysqli connection to server, but you are trying to make a mysql connection to database.To get going, rather use
$link = mysqli_connect("localhost","root","","web_table");
mysqli_select_db ($link , "web_table" ) or die.....
or for where i began
<?php $connection = mysqli_connect("localhost","root","","web_table");
global $connection; // global connection to databases - kill it once you're done
or just query with a $connection parameter as the other argument like above. Get rid of that third line.
For me it was missing MySQL PDO, I recompiled my PHP with the --with-pdo-mysql
option, installed it and restarted apache and it was all working
like this :
df.groupby('colour').size().plot(kind='bar')
In NodeJS if you know the ID
, the looping through the array is very slow compared to object[ID]
.
const uniqueString = require('unique-string');
const obj = {};
const arr = [];
var seeking;
//create data
for(var i=0;i<1000000;i++){
var getUnique = `${uniqueString()}`;
if(i===888555) seeking = getUnique;
arr.push(getUnique);
obj[getUnique] = true;
}
//retrieve item from array
console.time('arrTimer');
for(var x=0;x<arr.length;x++){
if(arr[x]===seeking){
console.log('Array result:');
console.timeEnd('arrTimer');
break;
}
}
//retrieve item from object
console.time('objTimer');
var hasKey = !!obj[seeking];
console.log('Object result:');
console.timeEnd('objTimer');
And the results:
Array result:
arrTimer: 12.857ms
Object result:
objTimer: 0.051ms
Even if the seeking ID is the first one in the array/object:
Array result:
arrTimer: 2.975ms
Object result:
objTimer: 0.068ms
Yes. bar.a
and bar.b
are set to true, but bar.c
is undefined. However, certain compilers will set it to false.
See a live example here: struct demo
According to C++ standard Section 8.5.12:
if no initialization is performed, an object with automatic or dynamic storage duration has indeterminate value
For primitive built-in data types (bool, char, wchar_t, short, int, long, float, double, long double), only global variables (all static storage variables) get default value of zero if they are not explicitly initialized.
If you don't really want undefined bar.c
to start with, you should also initialize it like you did for bar.a
and bar.b
.
I found a faster way of embedding:
Yes, I just hit my first 'PHP Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM'
. My bad, I had a $instance::method()
that should have been $instance->method()
. Silly me.
The odd thing is that this still works just fine on my local machine (running PHP 5.3.8) - nothing, not even a warning with error_reporting = E_ALL - but not at all on the test server, there it just explodes with a syntax error and a white screen in the browser. Since PHP logging was turned off at the test machine, and the hosting company was too busy to turn it on, it was not too obvious.
So, word of warning: apparently, some PHP installations will let you use a $instance::method(), while others don't.
If anybody can expand on why that is, please do.
You can do forward typedef. But to do
typedef A B;
you must first forward declare A
:
class A;
typedef A B;
For the best measure of elapsed time (since Python 3.3), use time.perf_counter()
.
Return the value (in fractional seconds) of a performance counter, i.e. a clock with the highest available resolution to measure a short duration. It does include time elapsed during sleep and is system-wide. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid.
For measurements on the order of hours/days, you don't care about sub-second resolution so use time.monotonic()
instead.
Return the value (in fractional seconds) of a monotonic clock, i.e. a clock that cannot go backwards. The clock is not affected by system clock updates. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid.
In many implementations, these may actually be the same thing.
Before 3.3, you're stuck with time.clock()
.
On Unix, return the current processor time as a floating point number expressed in seconds. The precision, and in fact the very definition of the meaning of “processor time”, depends on that of the C function of the same name.
On Windows, this function returns wall-clock seconds elapsed since the first call to this function, as a floating point number, based on the Win32 function QueryPerformanceCounter(). The resolution is typically better than one microsecond.
New in Python 3.7 is PEP 564 -- Add new time functions with nanosecond resolution.
Use of these can further eliminate rounding and floating-point errors, especially if you're measuring very short periods, or your application (or Windows machine) is long-running.
Resolution starts breaking down on perf_counter()
after around 100 days. So for example after a year of uptime, the shortest interval (greater than 0) it can measure will be bigger than when it started.
time.clock
is now gone.

This is also true for some other shells.
Here's how to do each of those options:
lockdir="somedir"
testlock(){
retval=""
if mkdir "$lockdir"
then # Directory did not exist, but it was created successfully
echo >&2 "successfully acquired lock: $lockdir"
retval="true"
else
echo >&2 "cannot acquire lock, giving up on $lockdir"
retval="false"
fi
echo "$retval"
}
retval=$( testlock )
if [ "$retval" == "true" ]
then
echo "directory not created"
else
echo "directory already created"
fi
lockdir="somedir"
testlock(){
if mkdir "$lockdir"
then # Directory did not exist, but was created successfully
echo >&2 "successfully acquired lock: $lockdir"
retval=0
else
echo >&2 "cannot acquire lock, giving up on $lockdir"
retval=1
fi
return "$retval"
}
testlock
retval=$?
if [ "$retval" == 0 ]
then
echo "directory not created"
else
echo "directory already created"
fi
lockdir="somedir"
retval=-1
testlock(){
if mkdir "$lockdir"
then # Directory did not exist, but it was created successfully
echo >&2 "successfully acquired lock: $lockdir"
retval=0
else
echo >&2 "cannot acquire lock, giving up on $lockdir"
retval=1
fi
}
testlock
if [ "$retval" == 0 ]
then
echo "directory not created"
else
echo "directory already created"
fi
This should give you a start

In addition to the already suggested cause of missing a class file this error can also indicate a duplicate class file, eclipse reports this error when an class file on the build path uses another class that has multiple definitions in the build path.
Super Key : Super key is a set of one or more attributes whose values identify tuple in the relation uniquely.
Candidate Key : Candidate key can be defined as a minimal subset of super key. In some cases , candidate key can not alone since there is alone one attribute is the minimal subset. Example,
Employee(id, ssn, name, addrress)
Here Candidate key is (id, ssn) because we can easily identify the tuple using either id or ssn . Althrough, minimal subset of super key is either id or ssn. but both of them can be considered as candidate key.
Primary Key : Primary key is a one of the candidate key.
Example : Student(Id, Name, Dept, Result)
Here
Super Key : {Id, Id+Name, Id+Name+Dept} because super key is set of attributes .
Candidate Key : Id because Id alone is the minimal subset of super key.
Primary Key : Id because Id is one of the candidate key
I am not very sure whether it will make any difference in performance of my API.
Bear in mind that the primary benefit of asynchronous code on the server side is scalability. It won't magically make your requests run faster. I cover several "should I use async
" considerations in my article on async
ASP.NET.
I think your use case (calling other APIs) is well-suited for asynchronous code, just bear in mind that "asynchronous" does not mean "faster". The best approach is to first make your UI responsive and asynchronous; this will make your app feel faster even if it's slightly slower.
As far as the code goes, this is not asynchronous:
public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
var response = _service.Process<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
return Task.FromResult(response);
}
You'd need a truly asynchronous implementation to get the scalability benefits of async
:
public async Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
return await _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}
Or (if your logic in this method really is just a pass-through):
public Task<BackOfficeResponse<List<Country>>> ReturnAllCountriesAsync()
{
return _service.ProcessAsync<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
}
Note that it's easier to work from the "inside out" rather than the "outside in" like this. In other words, don't start with an asynchronous controller action and then force downstream methods to be asynchronous. Instead, identify the naturally asynchronous operations (calling external APIs, database queries, etc), and make those asynchronous at the lowest level first (Service.ProcessAsync
). Then let the async
trickle up, making your controller actions asynchronous as the last step.
And under no circumstances should you use Task.Run
in this scenario.
Here's some JavaScript for copy-paste ease (this is irritate's answer):
function scaleBetween(unscaledNum, minAllowed, maxAllowed, min, max) {
return (maxAllowed - minAllowed) * (unscaledNum - min) / (max - min) + minAllowed;
}
Applied like so, scaling the range 10-50 to a range between 0-100.
var unscaledNums = [10, 13, 25, 28, 43, 50];
var maxRange = Math.max.apply(Math, unscaledNums);
var minRange = Math.min.apply(Math, unscaledNums);
for (var i = 0; i < unscaledNums.length; i++) {
var unscaled = unscaledNums[i];
var scaled = scaleBetween(unscaled, 0, 100, minRange, maxRange);
console.log(scaled.toFixed(2));
}
0.00, 18.37, 48.98, 55.10, 85.71, 100.00
Edit:
I know I answered this a long time ago, but here's a cleaner function that I use now:
Array.prototype.scaleBetween = function(scaledMin, scaledMax) {
var max = Math.max.apply(Math, this);
var min = Math.min.apply(Math, this);
return this.map(num => (scaledMax-scaledMin)*(num-min)/(max-min)+scaledMin);
}
Applied like so:
[-4, 0, 5, 6, 9].scaleBetween(0, 100);
[0, 30.76923076923077, 69.23076923076923, 76.92307692307692, 100]
To speed up loading modules, Python caches the compiled content of modules in .pyc.
CPython compiles its source code into "byte code", and for performance reasons, it caches this byte code on the file system whenever the source file has changes. This makes loading of Python modules much faster because the compilation phase can be bypassed. When your source file is foo.py , CPython caches the byte code in a foo.pyc file right next to the source.
In python3, Python's import machinery is extended to write and search for byte code cache files in a single directory inside every Python package directory. This directory will be called __pycache__ .
Here is a flow chart describing how modules are loaded:
