I know it's been a little over two years... but I was looking for a way to do this, and wasn't overly happy with the solution posted (it works fine, but I wanted a little more information as the import happens). When combining all the SQL files in to one, you don't get any sort of progress updates.
So I kept digging for an answer and thought this might be a good place to post what I found for future people looking for the same answer. Here's a command line in Windows that will import multiple SQL files from a folder. You run this from the command line while in the directory where mysql.exe is located.
for /f %f in ('dir /b <dir>\<mask>') do mysql --user=<user> --password=<password> <dbname> < <dir>\%f
With some assumed values (as an example):
for /f %f in ('dir /b c:\sqlbackup\*.sql') do mysql --user=mylogin --password=mypass mydb < c:\sqlbackup\%f
If you had two sets of SQL backups in the folder, you could change the *.sql to something more specific (like mydb_*.sql).
For me doesnt put jars to lib directory and set to Build path enought.
The right thing was add it to Deployment Assembly.
Because the designers of CSS didn't have the foresight to imagine the flexibility this would bring. There are plenty of reasons to expand the content area of a box without affecting its relationship to neighbouring elements. If you think it's not possible, put some long nowrap
'd text in a box, set a width on the box, and watch how the overflowed content does nothing to the layout.
Yes, this is still relevant with CSS3 in 2019; case in point: flexbox layouts. Flexbox items' margins do not collapse, so in order to space them evenly and align them with the visual edge of the container, one must subtract the items' margins from their container's padding. If any result is < 0, you must use a negative margin on the container, or sum that negative with the existing margin. I.e. the content of the element effects how one defines the margins for it, which is backwards. Summing doesn't work cleanly when flex elements' content have margins defined in different units or are affected by a different font-size, etc.
The example below should, ideally have aligned and evenly spaced grey boxes but, sadly they aren't.

I have encountered enough of these little issues over the years where a little negative padding would have gone a long way, but instead I'm forced to add non-semantic markup, use calc()
, or CSS preprocessors which only work when the units are the same, etc.
Short-sightedness, I'd guess.
When originally designed, interfaces were intended only to be used with instances of class
IMyInterface val = GetObjectImplementingIMyInterface();
val.SomeThingDefinedinInterface();
It was only with the introduction of interfaces as constraints for generics did adding a static method to an interface have a practical use.
(responding to comment:) I believe changing it now would require a change to the CLR, which would lead to incompatibilities with existing assemblies.
I don't know what the "preferred" method is (ask 100 people and get 100 different opinions) but do what's simplest and what works. GetName
works but requires a lot more keystrokes. ToString()
seems to do the job very well.
DBCC OPENTRAN helps to identify active transactions that may be preventing log truncation. DBCC OPENTRAN displays information about the oldest active transaction and the oldest distributed and nondistributed replicated transactions, if any, within the transaction log of the specified database. Results are displayed only if there is an active transaction that exists in the log or if the database contains replication information.
An informational message is displayed if there are no active transactions in the log.

To answer your second question, yes, you can cast the List<?>
as a List<Object>
or a List<T>
of any type, since the ?
(Wildcard) parameter indicates that the list contains a homogenous collection of an any Object
. However, there's no way to know at compile what the type
is since it's part of the exported API only - meaning you can't see what's being inserted into the List<?>
.
Here's how you would make the cast:
List<?> wildcardList = methodThatReturnsWildcardList();
// generates Unchecked cast compiler warning
List<Object> objectReference = (List<Object>)wildcardList;
In this case you can ignore the warning because in order for an object to be used in a generic class it must be a subtype of Object
. Let's pretend that we're trying to cast this as a List<Integer>
when it actually contains a collection of String
s.
// this code will compile safely
List<?> wildcardList = methodThatReturnsWildcardList();
List<Integer> integerReference = (List<Integer>)wildcardList;
// this line will throw an invalid cast exception for any type other than Integer
Integer myInteger = integerRefence.get(0);
Remember: generic types are erased at runtime. You won't know what the collection contains, but you can get an element and call .getClass()
on it to determine its type.
Class objectClass = wildcardList.get(0).getClass();
In Python, to represent the absence of a value, you can use the None value (types.NoneType.None) for objects and "" (or len() == 0) for strings. Therefore:
if yourObject is None: # if yourObject == None:
...
if yourString == "": # if yourString.len() == 0:
...
Regarding the difference between "==" and "is", testing for object identity using "==" should be sufficient. However, since the operation "is" is defined as the object identity operation, it is probably more correct to use it, rather than "==". Not sure if there is even a speed difference.
Anyway, you can have a look at:
try this
<script type="text/javascript">
window.onload = function(){
var auto_refresh = setInterval(
function ()
{
$('.View').html('');
$('.View').load('Small.php').fadeIn("slow");
}, 15000); // refresh every 15000 milliseconds
}
</script>
You can't use php code client-side. You need to use javascript.
<input type="button" value="Home" class="homebutton" id="btnHome"
onClick="document.location.href='some/page'" />
However, you really shouldn't be using inline js (like onclick here). Study about this here: https://www.google.com/search?q=Why+is+inline+js+bad%3F
Here's a clean way of doing this: Live demo (click).
Markup:
<button id="myBtn">Redirect</button>
JavaScript:
var btn = document.getElementById('myBtn');
btn.addEventListener('click', function() {
document.location.href = 'some/page';
});
If you need to write in the location with php:
<button id="myBtn">Redirect</button>
<script>
var btn = document.getElementById('myBtn');
btn.addEventListener('click', function() {
document.location.href = '<?php echo $page; ?>';
});
</script>
There are three ways to do what you want
This includes something like php, asp, jsp.... But you said no to that
Your server is serving up the pages so why not take advantage of the built in server side includes? Each server has its own way to do this, take advantage of it.
This solutions has you calling back to the server after page has already been loaded on the client.
Do as this:
Windows -> Show View -> Servers
Then in the Servers view, right-click and add new. It will show a pop up containing many server vendors. Under Apache select Tomcat v7.0 (Depending upon your downloaded server version). And in the run time configuration point it to the Tomcat folder you have downloaded.
You can try this article. It has the info you want !!
Try to assign the image that way instead:
imgFavorito.Source = new BitmapImage(new Uri(base.BaseUri, @"/Assets/favorited.png"));
I had a problem where the images would not show and it wasn't the relative path. I even hard coded the actual path and the image still did not show. I had changed my webserver to run on port 8080 and neither
<img src="c:/public/images/<?php echo $image->filename; ?>" width="100" />
<img src="c:/public/images/mypic.jpg" width="100" />
would not work.
<img src="../../images/<?php echo $photo->filename; ?>" width="100" />
Did not work either. This did work :
<img src="http://localhost:8080/public/images/<?php echo $image->filename; ?>" width="100" />
Windows communication Fundation(WCF) is used for connecting different applications and passing the data's between them using endpoints.
Windows Presentation Foundation is used for designing rich internet applications in the format of xaml.
From the Python language reference, under Function definitions:
Default parameter values are evaluated when the function definition is executed. This means that the expression is evaluated once, when the function is defined, and that that same “pre-computed” value is used for each call.
Fortunately, Django has a way to do what you want, if you use the auto_now
argument for the DateTimeField
:
date = models.DateTimeField(auto_now=True)
See the Django docs for DateTimeField.
This is not the most robust solution - but if you're just looking to create a partitioned rank on a field with only a few different values, it may not be unwieldily to use some case when logic with as many variables as you require.
Something like this has worked for me in the past:
SELECT t.*,
CASE WHEN <partition_field> = @rownum1 := @rownum1 + 1
WHEN <partition_field> = @rownum2 := @rownum2 + 1
...
END AS rank
FROM YOUR_TABLE t,
(SELECT @rownum1 := 0) r1, (SELECT @rownum2 := 0) r2
ORDER BY <rank_order_by_field>
;
Hope that makes sense / helps!
array1.NonIntersect(array2);
Nonintersect such operator is not present in Linq you should do
except -> union -> except
a.except(b).union(b.Except(a));

Our Company is using a Nexus Repository Manager as a npm registry (we do not access https://registry.npmjs.org/ directly), the version was so new, that it wasn't included yet in our Nexus yet.
Invalidating the cache of the repository and npm install
fixed the issue.
The NASDAQ site hosts separate CSV lists for ticker symbols in each stock exchange (NYSE, AMEX and NASDAQ). You need to complete the captcha and get the CSV dump.
You should disable Power Save Mode
For me I clicked over this button
then disable Power Save Mode
This one-liner should work:
npm start --prefix path/to/your/app
Why do you need to state both 'x' and 'y' before the ':'?
Because a lambda is (conceptually) the same as a function, just written inline. Your example is equivalent to
def f(x, y) : return x + y
just without binding it to a name like f
.
Also how do you make it return multiple arguments?
The same way like with a function. Preferably, you return a tuple:
lambda x, y: (x+y, x-y)
Or a list, or a class, or whatever.
The thing with self.entry_1.bind
should be answered by Demosthenex.
It sounds like you have file in the git repo owned by root. Since you're ssh'ing in as 'username' to do the push, the files must be writable by username. The easiest thing is probably to create the repo as the user, and use the same user to do your pushes. Another option is to create a group, make everything writable by the group, and make your user a member of that group.
Hope this wins the race due to its performance and most important not a chained logic using .replace('&','&').replace('<','<')...
var mapObj = {
'&':"&",
'<':"<",
'>':">",
'"':""",
'\'':"'"
};
var re = new RegExp(Object.keys(mapObj).join("|"),"gi");
function escapeHtml(str)
{
return str.replace(re, function(matched)
{
return mapObj[matched.toLowerCase()];
});
}
console.log('<script type="text/javascript">alert('Hello World');</script>');
console.log(escapeHtml('<script type="text/javascript">alert('Hello World');</script>'));
Here are some:
"Ali".eql? "Ali"
=> true
The spaceship (<=>
) method can be used to compare two strings in relation to their alphabetical ranking. The <=> method returns 0 if the strings are identical, -1 if the left hand string is less than the right hand string, and 1 if it is greater:
"Apples" <=> "Apples"
=> 0
"Apples" <=> "Pears"
=> -1
"Pears" <=> "Apples"
=> 1
A case insensitive comparison may be performed using the casecmp method which returns the same values as the <=> method described above:
"Apples".casecmp "apples"
=> 0
The registry change mechanism worked for me after a struggle. Actually my application was running as 32bit. So I had to change the value under path.
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft.NETFramework\v4.0.30319
The value type needs to be DWORD and value above 0 .Better use 1.
I had the same problem.
I solved it doing this:
I created the following line in the
primary key: (id int(11) unsigned NOT NULL AUTO_INCREMENT)
I found out this solution after trying to import a table in my schema builder. If it works for you, let me know!
Good luck!

An easy fix to this question is to add '[' in the start of your json file, and ending it with a ']'. This solved it for me.
it seems that the
yum install ruby-devel
was enough for me to perform
gem install datamapper
afterwards.
It's possible that you will need to install another packages:
yum install gcc gcc-c++
to be able to build native extensions
For both speed and memory purposes, when building a large data frame via some complex series of steps, I'll periodically flush it (the in-progress data set being built) to disk, appending to anything that came before, and then restart it. This way the intermediate steps are only working on smallish data frames (which is good as, e.g., rbind slows down considerably with larger objects). The entire data set can be read back in at the end of the process, when all the intermediate objects have been removed.
dfinal <- NULL
first <- TRUE
tempfile <- "dfinal_temp.csv"
for( i in bigloop ) {
if( !i %% 10000 ) {
print( i, "; flushing to disk..." )
write.table( dfinal, file=tempfile, append=!first, col.names=first )
first <- FALSE
dfinal <- NULL # nuke it
}
# ... complex operations here that add data to 'dfinal' data frame
}
print( "Loop done; flushing to disk and re-reading entire data set..." )
write.table( dfinal, file=tempfile, append=TRUE, col.names=FALSE )
dfinal <- read.table( tempfile )
I believe this is what you want:
DataTable dtTable = new DataTable();
foreach (DataRow dtRow in dtTable.Rows)
{
foreach (DataColumn dc in dtRow.ItemArray)
{
}
}
I was having the same issue, but with Glide. When I was going to disconnect from wifi and reconnect (just like it was suggested here), I noticed that I was in Airplane mode ???
This should work fine for you.
Write this code in the Page_Load
event of the page.
string ID = Request.QueryString["id"].ToString();
Response.Redirect("http://www.example.com/rendernews.php?id=" + ID);
In mvc 4 you can easily do it like following using TextBoxFor
..
@Html.TextBoxFor(m => m.StartDate, "{0:MM/dd/yyyy}", new { @class = "form-control default-date-picker" })
So, you don't need to use any data annotation in model or view model class
Fluid layout in Bootstrap 3.
Unlike Boostrap 2, Bootstrap 3 doesn't have a .container-fluid mixin to make a fluid container. The .container is a fixed width responsive grid layout. In a large screen, there are excessive white spaces in both sides of one's Web page content.
container-fluid
is added back in Bootstrap 3.1
A fluid grid layout uses all screen width and works better in large screen. It turns out that it is easy to create a fluid grid layout using Bootstrap 3 mixins. The following line makes a fluid responsive grid layout:
.container-fixed;
The .container-fixed mixin sets the content to the center of the screen and add paddings. It doesn't specifies a fixed page width.
Another approach is to use Eric Flowers' CSS style
.my-fluid-container {
padding-left: 15px;
padding-right: 15px;
margin-left: auto;
margin-right: auto;
}
You can use the ATL text conversion macros to convert a narrow (char) string to a wide (wchar_t) one. For example, to convert a std::string:
#include <atlconv.h>
...
std::string str = "Hello, world!";
CA2W pszWide(str.c_str());
loadU(pszWide);
You can also specify a code page, so if your std::string contains UTF-8 chars you can use:
CA2W pszWide(str.c_str(), CP_UTF8);
Very useful but Windows only.
The no-js class is used to style a webpage, dependent on whether the user has JS disabled or enabled in the browser.
As per the Modernizr docs:
no-js
By default, Modernizr will rewrite
<html class="no-js"> to <html class="js">
. This lets hide certain elements that should only be exposed in environments that execute JavaScript. If you want to disable this change, you can set enableJSClass to false in your config.
nohup some_command &> nohup2.out &
and voila.
Older syntax for Bash version < 4:
nohup some_command > nohup2.out 2>&1 &
Another alternative, in my mind a better one, is using Pendulum
instead of pytz
. Consider the following simple code:
>>> import pendulum
>>> dt = pendulum.now().to_iso8601_string()
>>> print (dt)
2018-03-27T13:59:49+03:00
>>>
To install Pendulum and see their documentation, go here. It have tons of options (like simple ISO8601, RFC3339 and many others format support), better performance and tend to yield simpler code.
At eBay it’s the kabob.
Also heard it called the snowman or sushi roll.
It is always an option to enter python on the command line with the command python
then import your file so import example_file
then run the command with example_file.hello()
This avoids the weird .pyc copy function that crops up every time you run python -c etc.
Maybe not as convenient as a single-command, but a good quick fix to text a file from the command line, and allows you to use python to call and execute your file.
Edit: it's 2020, I would use flex box instead.
Original answer:
Html
<body>
<div class="centered">
</div>
</body>
CSS
.centered {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
in case you don't want to type all that, here's a shorter way to query by data attribute:
$("ul[data-slide='" + current +"']");
FYI: http://james.padolsey.com/javascript/a-better-data-selector-for-jquery/
Found a comparison of the 2 techniques (query string vs file name) here:
Version as a querystring has two problems.
First, it may not always be a browser that implements caching through which we need to bust. It is said that certain (possibly older) proxies do ignore the querystring with respect to their caching behavior.
Second, in certain more complex deployment scenarios, where you have multiple frontend and/or multiple backend servers, an upgrade is anything but instantaneous. You need to be able to serve both the old and the new version of your assets at the same time. See for example how this affects you when using Google App Engine.
The plain and simple answer is yes, VanillaJS === JavaScript, as prescribed by Dr B. Eich.
import java.util.Arrays;
class Soft{
public static void main(String[] args){
int[] nums=range(9, 12);
System.out.println(Arrays.toString(nums));
}

int[] a=new int[high-low];
for(int i=0,j=low;i<high-low;i++,j++){
a[i]=j;
}
return a;
}
}
My code is similar to Python`s range :)

In a very simple sentence, we can say:
The child class must not violate its base class characteristics. It must be capable with it. We can say it's same as subtyping.
As all the earlier answers are old, and due to ever changing policies from facebook other mentioned answers might not work for permanent tokens.
After lot of debugging ,I am able to get the never expires token using following steps:
Graph API Explorer:
Thats it
The following returns the first word in cell A1 when separated by a space (works in Excel 2003):
=LEFT(A1, SEARCH(" ",A1,1))
Quickfix
I had similar issue and I resolved it doing the following
Alternative 1: Disable sandbox
As this article explains in depth, groovy scripts are run in sandbox mode by default. This means that a subset of groovy methods are allowed to run without administrator approval. It's also possible to run scripts not in sandbox mode, which implies that the whole script needs to be approved by an administrator at once. This preventing users from approving each line at the time.
Running scripts without sandbox can be done by unchecking this checkbox in your project config just below your script:
Alternative 2: Disable script security
As this article explains it also possible to disable script security completely. First install the permissive script security plugin and after that change your jenkins.xml file add this argument:
-Dpermissive-script-security.enabled=true
So you jenkins.xml will look something like this:
<executable>..bin\java</executable>
<arguments>-Dpermissive-script-security.enabled=true -Xrs -Xmx4096m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=80 --webroot="%BASE%\war"</arguments>
Make sure you know what you are doing if you implement this!
If you use another view
make sure to use view.getContext()
instead of this
or getApplicationContext()
Install This Chrome-plugin for Disable-web-security in Chrome::
" Allow-Control-Allow-Origin: * " link Here or you can google above plugin if you want.
it is very easy to enable and disable the security with this plugin.
From angular's documentation,
ng-init SHOULD NOT be used for any initialization. It should be used only for aliasing. https://docs.angularjs.org/api/ng/directive/ngInit
onload should be used if any expression needs to be evaluated after a partial view is loaded (by ng-include). https://docs.angularjs.org/api/ng/directive/ngInclude
The major difference between them is when used with ng-include.
<div ng-include="partialViewUrl" onload="myFunction()"></div>
In this case, myFunction is called everytime the partial view is loaded.
<div ng-include="partialViewUrl" ng-init="myFunction()"></div>
Whereas, in this case, myFunction is called only once when the parent view is loaded.
There's a hack I've used since the Invoke-Expression works fine for me.
You could set the current location to the path with spaces, invoke the expression, get back to your previous location and continue:
$currLocation = Get-Location
Set-Location = "C:\Windows Services\"
Invoke-Expression ".\MyService.exe"
Set-Location $currLocation
This will only work if the exe doesn't have any spaces in its name.
Hope this helps
GraalVM is a good choice. I've done Java+Javascript combination with GraalVM for microservice design (Java with Javascript reflection). They recently added support for python, I'd give it a try especially with how big its community has grown over the years.
Is JSTL's join()
, what you searched for?
<c:set var="myVar" value="${fn:join(myParams.items, ' ')}" />
I had to add "Current" using .NET 4.5:
HttpContext.Current.Server.ScriptTimeout = 300;
try using form collection
<input id="responsable" value="True" name="checkResp" type="checkbox" />
[HttpPost]
public ActionResult Index(FormCollection collection)
{
if(!string.IsNullOrEmpty(collection["checkResp"])
{
string checkResp=collection["checkResp"];
bool checkRespB=Convert.ToBoolean(checkResp);
}
}
The problem with taking IEnumerable
as a parameter is that it tells callers "I wish to enumerate this". It doesn't tell them how many times you wish to enumerate.
I can change the objects parameter to be List and then avoid the possible multiple enumeration but then I don't get the highest object that I can handle.
The goal of taking the highest object is noble, but it leaves room for too many assumptions. Do you really want someone to pass a LINQ to SQL query to this method, only for you to enumerate it twice (getting potentially different results each time?)
The semantic missing here is that a caller, who perhaps doesn't take time to read the details of the method, may assume you only iterate once - so they pass you an expensive object. Your method signature doesn't indicate either way.
By changing the method signature to IList
/ICollection
, you will at least make it clearer to the caller what your expectations are, and they can avoid costly mistakes.
Otherwise, most developers looking at the method might assume you only iterate once. If taking an IEnumerable
is so important, you should consider doing the .ToList()
at the start of the method.
It's a shame .NET doesn't have an interface that is IEnumerable + Count + Indexer, without Add/Remove etc. methods, which is what I suspect would solve this problem.
Here's what I use:
<logger name="org.hibernate">
<level value="warn"/>
</logger>
<logger name="org.hibernate.SQL">
<level value="warn"/>
</logger>
<logger name="org.hibernate.type">
<level value="warn"/>
</logger>
<root>
<priority value="info"/>
<appender-ref ref="C1"/>
</root>
Obviously, I don't like to see Hibernate messages ;) -- set the level to "debug" to get the output.
Maybe you can try the following :
var i = 0;
function AjaxSendForm(url, placeholder, form, append) {
var data = $(form).serialize();
append = (append === undefined ? false : true); // whatever, it will evaluate to true or false only
$.ajax({
type: 'POST',
url: url,
data: data,
beforeSend: function() {
// setting a timeout
$(placeholder).addClass('loading');
i++;
},
success: function(data) {
if (append) {
$(placeholder).append(data);
} else {
$(placeholder).html(data);
}
},
error: function(xhr) { // if error occured
alert("Error occured.please try again");
$(placeholder).append(xhr.statusText + xhr.responseText);
$(placeholder).removeClass('loading');
},
complete: function() {
i--;
if (i <= 0) {
$(placeholder).removeClass('loading');
}
},
dataType: 'html'
});
}
This way, if the beforeSend
statement is called before the complete
statement i
will be greater than 0 so it will not remove the class. Then only the last call will be able to remove it.
I cannot test it, let me know if it works or not.
You can use the function difftime
. It returns the difference between two given time_t
values, the output value is double
(see difftime documentation).
time_t actual_time;
double actual_time_sec;
actual_time = time(0);
actual_time_sec = difftime(actual_time,0);
printf("%g",actual_time_sec);
My 2 cents:
select DATEADD(DAY,-1,DATEADD(MONTH,1,DATEADD(day,(0-(DATEPART(dd,'2008-02-12')-1)),'2008-02-12')))

You are probably trying to push to a private repository. In that case, you will have to ask the admin for Collaborator access to be authenticated.
SELECT GETDATE() + (hours / 24.00000000000000000)
Adding to GETDATE() defaults to additional days, but it will also convert down to hours/seconds/milliseconds using decimal.
thisTag = _tags.FirstOrDefault(t => t.Key == tag);
is an inefficient and a little bit strange way to find something by key in a dictionary. Looking things up for a Key is the basic function of a Dictionary.
The basic solution would be:
if (_tags.Containskey(tag)) { string myValue = _tags[tag]; ... }
But that requires 2 lookups.
TryGetValue(key, out value)
is more concise and efficient, it only does 1 lookup. And that answers the last part of your question, the best way to do a lookup is:
string myValue;
if (_tags.TryGetValue(tag, out myValue)) { /* use myValue */ }
VS 2017 update, for C# 7 and beyond we can declare the result variable inline:
if (_tags.TryGetValue(tag, out string myValue))
{
// use myValue;
}
// use myValue, still in scope, null if not found
You shouldn't have to make any changes to the certificate. Are you sure you are running the right import command?
The following works for me:

Never give borderRadius to your <Text />
always wrap that <Text />
inside your <View />
or in your <TouchableOpacity/>
.
borderRadius on <Text />
will work perfectly on Android devices. But on IOS devices it won't work.
So keep this in your practice to wrap your <Text/>
inside your <View/>
or on <TouchableOpacity/>
and then give the borderRadius to that <View />
or <TouchableOpacity />
so that it will work on both Android as well as on IOS devices.
For example:-
<TouchableOpacity style={{borderRadius: 15}}>
<Text>Button Text</Text>
</TouchableOpacity>
-Thanks
Below code might help you to copy the first level objects
let original = [{ a: 1 }, {b:1}]
const copy = [ ...original ].map(item=>({...item}))
so for below case, values remains intact
copy[0].a = 23
console.log(original[0].a) //logs 1 -- value didn't change voila :)
Fails for this case
let original = [{ a: {b:2} }, {b:1}]
const copy = [ ...original ].map(item=>({...item}))
copy[0].a.b = 23;
console.log(original[0].a) //logs 23 -- lost the original one :(
Final advice:
I would say go for lodash cloneDeep
API which helps you to copy the objects inside objects completely dereferencing from original one's. This can be installed as a separate module.
Refer documentation: https://github.com/lodash/lodash
Individual Package : https://www.npmjs.com/package/lodash.clonedeep
One case I found where setAttribute
is necessary is when changing ARIA attributes, since there are no corresponding properties. For example
x.setAttribute('aria-label', 'Test');
x.getAttribute('aria-label');
There's no x.arialabel
or anything like that, so you have to use setAttribute.
Edit: x["aria-label"] does not work. You really do need setAttribute.
x.getAttribute('aria-label')
null
x["aria-label"] = "Test"
"Test"
x.getAttribute('aria-label')
null
x.setAttribute('aria-label', 'Test2')
undefined
x["aria-label"]
"Test"
x.getAttribute('aria-label')
"Test2"
According to the documentation, you should be able to switch back and forth like this:
In [2]: %matplotlib inline
In [3]: plot(...)
In [4]: %matplotlib qt # wx, gtk, osx, tk, empty uses default
In [5]: plot(...)
and that will pop up a regular plot window (a restart on the notebook may be necessary).
I hope this helps.
Since I had a similar question this got me a fast start.
My question is a bit more specific, 'what is the fastest method for a reflexive array implementation'
The testing done by Marc Gravell shows a lot, but not exactly access timing. His timing include the looping over the array's and lists as well. Since I also came up with a third method that I wanted to test, a 'Dictionary', just to compare, I extended hist test code.
Firts, I do a test using a constant, which gives me a certain timing including the loop. This is a 'bare' timing, excluding the actual access. Then I do a test with accessing the subject structure, this gives me and 'overhead included' timing, looping and actual access.
The difference between 'bare' timing and 'overhead indluded' timing gives me an indication of the 'structure access' timing.
But how accurate is this timing? During the test windows will do some time slicing for shure. I have no information about the time slicing but I asume it is evenly distributed during the test and in the order of tens of msec which means that the accuracy for the timing should be in the order of +/- 100 msec or so. A bit rough estimate? Anyway a source of a systematic mearure error.
Also, the tests were done in 'Debug' mode with no optimalisation. Otherwise the compiler might change the actual test code.
So, I get two results, one for a constant, marked '(c)', and one for access marked '(n)' and the difference 'dt' tells me how much time the actual access takes.
And this are the results:
Dictionary(c)/for: 1205ms (600000000)
Dictionary(n)/for: 8046ms (589725196)
dt = 6841
List(c)/for: 1186ms (1189725196)
List(n)/for: 2475ms (1779450392)
dt = 1289
Array(c)/for: 1019ms (600000000)
Array(n)/for: 1266ms (589725196)
dt = 247
Dictionary[key](c)/foreach: 2738ms (600000000)
Dictionary[key](n)/foreach: 10017ms (589725196)
dt = 7279
List(c)/foreach: 2480ms (600000000)
List(n)/foreach: 2658ms (589725196)
dt = 178
Array(c)/foreach: 1300ms (600000000)
Array(n)/foreach: 1592ms (589725196)
dt = 292
dt +/-.1 sec for foreach
Dictionary 6.8 7.3
List 1.3 0.2
Array 0.2 0.3
Same test, different system:
dt +/- .1 sec for foreach
Dictionary 14.4 12.0
List 1.7 0.1
Array 0.5 0.7
With better estimates on the timing errors (how to remove the systematic measurement error due to time slicing?) more could be said about the results.
It looks like List/foreach has the fastest access but the overhead is killing it.
The difference between List/for and List/foreach is stange. Maybe some cashing is involved?
Further, for access to an array it does not matter if you use a for
loop or a foreach
loop. The timing results and its accuracity makes the results 'comparible'.
Using a dictionary is by far the slowest, I only considered it because on the left side (the indexer) I have a sparse list of integers and not a range as is used in this tests.
Here is the modified test code.

It is possible to override the compatibility mode in intranet.
For IIS, just add the below code to the web.config. Worked for me with IE9.
<system.webServer>
<httpProtocol>
<customHeaders>
<clear />
<add name="X-UA-Compatible" value="IE=edge" />
</customHeaders>
</httpProtocol>
</system.webServer>
Equivalent for Apache:
Header set X-UA-Compatible: IE=Edge
And for nginx:
add_header "X-UA-Compatible" "IE=Edge";
And for express.js:
res.set('X-UA-Compatible', 'IE=Edge')

The simplest way is to map over the DataFrame's RDD and use mkString:
df.rdd.map(x=>x.mkString(","))
As of Spark 1.5 (or even before that)
df.map(r=>r.mkString(","))
would do the same
if you want CSV escaping you can use apache commons lang for that. e.g. here's the code we're using
def DfToTextFile(path: String,
df: DataFrame,
delimiter: String = ",",
csvEscape: Boolean = true,
partitions: Int = 1,
compress: Boolean = true,
header: Option[String] = None,
maxColumnLength: Option[Int] = None) = {
def trimColumnLength(c: String) = {
val col = maxColumnLength match {
case None => c
case Some(len: Int) => c.take(len)
}
if (csvEscape) StringEscapeUtils.escapeCsv(col) else col
}
def rowToString(r: Row) = {
val st = r.mkString("~-~").replaceAll("[\\p{C}|\\uFFFD]", "") //remove control characters
st.split("~-~").map(trimColumnLength).mkString(delimiter)
}
def addHeader(r: RDD[String]) = {
val rdd = for (h <- header;
if partitions == 1; //headers only supported for single partitions
tmpRdd = sc.parallelize(Array(h))) yield tmpRdd.union(r).coalesce(1)
rdd.getOrElse(r)
}
val rdd = df.map(rowToString).repartition(partitions)
val headerRdd = addHeader(rdd)
if (compress)
headerRdd.saveAsTextFile(path, classOf[GzipCodec])
else
headerRdd.saveAsTextFile(path)
}
To expand on zombat's answer (which I believe to be the best answer), I created a recursive version of his function that takes in a $limit
parameter to specify how many occurrences you want to replace.
function str_replace_limit($haystack, $needle, $replace, $limit, $start_pos = 0) {
if ($limit <= 0) {
return $haystack;
} else {
$pos = strpos($haystack,$needle,$start_pos);
if ($pos !== false) {
$newstring = substr_replace($haystack, $replace, $pos, strlen($needle));
return str_replace_limit($newstring, $needle, $replace, $limit-1, $pos+strlen($replace));
} else {
return $haystack;
}
}
}
For me none of working:
Function:
private String getCapsSentences(String tagName) {
String[] splits = tagName.toLowerCase().split(" ");
StringBuilder sb = new StringBuilder();
for (int i = 0; i < splits.length; i++) {
String eachWord = splits[i];
if (i > 0 && eachWord.length() > 0) {
sb.append(" ");
}
String cap = eachWord.substring(0, 1).toUpperCase()
+ eachWord.substring(1);
sb.append(cap);
}
return sb.toString();
}

Furthermore, if in the same Jenkins project we need to checkout several private GitHub repositories into several separate dirs under a project root. How can we do it please?
The Jenkin's Multiple SCMs Plugin has solved the several repositories problem for me very nicely. I have just got working a project build that checks out four different git repos under a common folder. (I'm a bit reluctant to use git super-projects as suggested previously by Lukasz Rzanek, as git is complex enough without submodules.)
Json isn't a huge language to start with, so libraries for it are likely to be small(er than Xml libraries, at least).
There are a whole ton of C libraries linked at Json.org. Maybe one of them will work well for you.
If I understand your question correctly, you are asking how you can create class level constants (static - in C++ parlance) such that you don't a) replicate the overhead in every instance, and b have to recompute what is otherwise constant.
The language has evolved - as every reader knows, but as I test this in Xcode 6.3.1, the solution is:
import Swift
class MyClass {
static let testStr = "test"
static let testStrLen = count(testStr)
init() {
println("There are \(MyClass.testStrLen) characters in \(MyClass.testStr)")
}
}
let a = MyClass()
// -> There are 4 characters in test
I don't know if the static is strictly necessary as the compiler surely only adds only one entry per const variable into the static section of the binary, but it does affect syntax and access. By using static, you can refer to it even when you don't have an instance: MyClass.testStrLen
.
The problem is that the actual width of an a
tag depends on its contents. Your code has no text in the a
tag, so it appears like a hunger-sunken circle. If you use the div
tag along the a
, you get the desired results.
Check this code out:
.btn {
background-color: green;
border-radius: 50%;
/*this will rounden-up the button*/
width: 80px;
height: 80px;
/*keep the height and width equal*/
}
_x000D_
<a href="#">
<!--use the URL you want to use-->
<button class="btn">press me</button>
</a>
_x000D_
To control the background-color
of the scrollbar, you need to target the primary element, instead of -track
.
::-webkit-scrollbar {
background-color: blue;
}
::-webkit-scrollbar-track {
-webkit-box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.3);
}
I haven't succeeded in rendering it transparent
, but I did manage to set its color.
Since this is limited to webkit, it is still preferable to use JS with a polyfill: CSS customized scroll bar in div
With Spring you can also just write the following using AnnotationUtils class. i.e.:
Class<?> clazz = AnnotationUtils.findAnnotationDeclaringClass(Target.class, null);
For more details and all different methods check official docs: https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/core/annotation/AnnotationUtils.html
Assume, you have installed the latest gradle once. But, If your particular project gradle version not match with the gradle version that already installed in the machine, the gradle sycn want to download that version. To prevent this download there is one trick. First You have to know the gradle version that already installed in your machine. Go to : C:\Users{username}.gradle\wrapper\dists, here you see the versions allready installed, remember the latest version, assume it is gradle-6.1.1-all.zip . Now, come back to Android Studio. In your Opened project, navigate Android Studio's project tree, open the file gradle/wrapper/gradle-wrapper.properties. Change this entry:
distributionUrl=http\://services.gradle.org/distributions/gradle-6.1.1-all.zip
This way we prevent downloading the gradle again and again. But avoid this thing, if the version really old. If that, you will find this warning :
Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/6.1.1/userguide/command_line_interface.html#sec:command_line_warnings
As much as I prefer this approach:-
api.com/users?id=id1,id2,id3,id4,id5
The correct way is
api.com/users?ids[]=id1&ids[]=id2&ids[]=id3&ids[]=id4&ids[]=id5
or
api.com/users?ids=id1&ids=id2&ids=id3&ids=id4&ids=id5
This is how rack does it. This is how php does it. This is how node does it as well...
Thanks for the help. I've managed to get it working now so thought I would post so that the others can use to help them.
Server:
public class Server {
public static void main(String[] args) throws IOException {
ServerSocket serverSocket = null;
try {
serverSocket = new ServerSocket(4444);
} catch (IOException ex) {
System.out.println("Can't setup server on this port number. ");
}
Socket socket = null;
InputStream in = null;
OutputStream out = null;
try {
socket = serverSocket.accept();
} catch (IOException ex) {
System.out.println("Can't accept client connection. ");
}
try {
in = socket.getInputStream();
} catch (IOException ex) {
System.out.println("Can't get socket input stream. ");
}
try {
out = new FileOutputStream("M:\\test2.xml");
} catch (FileNotFoundException ex) {
System.out.println("File not found. ");
}
byte[] bytes = new byte[16*1024];
int count;
while ((count = in.read(bytes)) > 0) {
out.write(bytes, 0, count);
}
out.close();
in.close();
socket.close();
serverSocket.close();
}
}
and the Client:
public class Client {
public static void main(String[] args) throws IOException {
Socket socket = null;
String host = "127.0.0.1";
socket = new Socket(host, 4444);
File file = new File("M:\\test.xml");
// Get the size of the file
long length = file.length();
byte[] bytes = new byte[16 * 1024];
InputStream in = new FileInputStream(file);
OutputStream out = socket.getOutputStream();
int count;
while ((count = in.read(bytes)) > 0) {
out.write(bytes, 0, count);
}
out.close();
in.close();
socket.close();
}
}
I'm thinking maybe run doCalculations; echo "$?" >>/tmp/acc
in a subshell that is sent to the background, then the wait
, then /tmp/acc
would contain the exit statuses, one per line. I don't know about any consequences of the multiple processes appending to the accumulator file, though.
Here's a trial of this suggestion:
File: doCalcualtions
#!/bin/sh
random -e 20
sleep $?
random -e 10
File: try
#!/bin/sh
rm /tmp/acc
for i in $( seq 0 20 )
do
( ./doCalculations "$i"; echo "$?" >>/tmp/acc ) &
done
wait
cat /tmp/acc | fmt
rm /tmp/acc
Output of running ./try
5 1 9 6 8 1 2 0 9 6 5 9 6 0 0 4 9 5 5 9 8
I'm adding this answer late since this is the answer that pops up most on Google...
You can use PHP to...
$url = "www.google.co.uk";
$host = parse_url($url, PHP_URL_HOST);
// $host == "www.google.co.uk"
to grab the host but not the private domain to which the host refers. (Example www.google.co.uk
is the host, but google.co.uk
is the private domain)
To grab the private domain, you must need know the list of public suffixes to which one can register a private domain. This list happens to be curated by Mozilla at https://publicsuffix.org/
The below code works when an array of public suffixes has been created already. Simply call
$domain = get_private_domain("www.google.co.uk");
with the remaining code...
// find some way to parse the above list of public suffix
// then add them to a PHP array
$suffix = [... all valid public suffix ...];
function get_public_suffix($host) {
$parts = split("\.", $host);
while (count($parts) > 0) {
if (is_public_suffix(join(".", $parts)))
return join(".", $parts);
array_shift($parts);
}
return false;
}
function is_public_suffix($host) {
global $suffix;
return isset($suffix[$host]);
}
function get_private_domain($host) {
$public = get_public_suffix($host);
$public_parts = split("\.", $public);
$all_parts = split("\.", $host);
$private = [];
for ($x = 0; $x < count($public_parts); ++$x)
$private[] = array_pop($all_parts);
if (count($all_parts) > 0)
$private[] = array_pop($all_parts);
return join(".", array_reverse($private));
}
sys .argv will display the command line args passed when running a script or you can say sys.argv will store the command line arguments passed in python while running from terminal.
Just try this:
import sys
print sys.argv
argv stores all the arguments passed in a python list. The above will print all arguments passed will running the script.
Now try this running your filename.py like this:
python filename.py example example1
this will print 3 arguments in a list.
sys.argv[0] #is the first argument passed, which is basically the filename.
Similarly, argv1 is the first argument passed, in this case 'example'
A similar question has been asked already here btw. Hope this helps!
Just stumbled upon this problem, and none of these solutions worked for me. What turned out to be the solution for my issue is actually much simpler: upgrade Git. Mine was 1.7.1, and after I upgraded it to 2.16.1 (latest), the problem went away without a trace! Guess I'm leaving it here, hope it helps someone.
A simple example for the usage of JSONP.
client.html
<html>
<head>
</head>
body>
<input type="button" id="001" onclick=gO("getCompany") value="Company" />
<input type="button" id="002" onclick=gO("getPosition") value="Position"/>
<h3>
<div id="101">
</div>
</h3>
<script type="text/javascript">
var elem=document.getElementById("101");
function gO(callback){
script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'http://localhost/test/server.php?callback='+callback;
elem.appendChild(script);
elem.removeChild(script);
}
function getCompany(data){
var message="The company you work for is "+data.company +"<img src='"+data.image+"'/ >";
elem.innerHTML=message;
}
function getPosition(data){
var message="The position you are offered is "+data.position;
elem.innerHTML=message;
}
</script>
</body>
</html>
server.php
<?php
$callback=$_GET["callback"];
echo $callback;
if($callback=='getCompany')
$response="({\"company\":\"Google\",\"image\":\"xyz.jpg\"})";
else
$response="({\"position\":\"Development Intern\"})";
echo $response;
?>
I don't think there is, but you can do something like this:
enum choices {a1, a2, b1, b2};
public static boolean exists(choices choice) {
for(choice aChoice : choices.values()) {
if(aChoice == choice) {
return true;
}
}
return false;
}
Edit:
Please see Richard's version of this as it is more appropriate as this won't work unless you convert it to use Strings, which Richards does.
There are various ways to handle this more elegantly now. Please see some other answers on this thread. Tech moves fast so answers can often become out of date fairly quickly. My answer will still work but it's worth looking at alternatives as well.
Using your code, the issue is that you haven't waited for a socket to be assigned to the request before attempting to set stuff on the socket object. It's all async so:
var options = { ... }
var req = http.request(options, function(res) {
// Usual stuff: on(data), on(end), chunks, etc...
});
req.on('socket', function (socket) {
socket.setTimeout(myTimeout);
socket.on('timeout', function() {
req.abort();
});
});
req.on('error', function(err) {
if (err.code === "ECONNRESET") {
console.log("Timeout occurs");
//specific error treatment
}
//other error treatment
});
req.write('something');
req.end();
The 'socket' event is fired when the request is assigned a socket object.
The below 'd help you to add the cert to the Root Store-
certutil -enterprise -f -v -AddStore "Root" <Cert File path>
This worked for me perfectly.
You might need a ~/.ssh/config
:
Host gitlab.YOURDOMAIN.DOMAIN
Port 1111
IdentityFile ~/.ssh/id_rsa
and then you can use git clone git@DOMAINandREPOSITORY
. This means you always use the user git
.
For Laravel 5.3 above:
php artisan make:controller test/TestController
This will create the test
folder if it does not exist, then creates TestController
inside.
TestController
will look like this:
<?php
namespace App\Http\Controllers\test;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class TestController extends Controller
{
public function getTest()
{
return "Yes";
}
}
You can then register your route this way:
Route::get('/test','test\TestController@getTest');
If you're using bootstrap 3 date time picker, try this:
$('.selector').datetimepicker({ maxDate: $.now() });
Try this please, <a target="_blank" routerLink="/Page2">
Update1: Custom directives to the rescue! Full code is here: https://github.com/pokearound/angular2-olnw
import { Directive, ElementRef, HostListener, Input, Inject } from '@angular/core';
@Directive({ selector: '[olinw007]' })
export class OpenLinkInNewWindowDirective {
//@Input('olinwLink') link: string; //intro a new attribute, if independent from routerLink
@Input('routerLink') link: string;
constructor(private el: ElementRef, @Inject(Window) private win:Window) {
}
@HostListener('mousedown') onMouseEnter() {
this.win.open(this.link || 'main/default');
}
}
Notice, Window is provided and OpenLinkInNewWindowDirective declared below:
import { AppAboutComponent } from './app.about.component';
import { AppDefaultComponent } from './app.default.component';
import { PageNotFoundComponent } from './app.pnf.component';
import { OpenLinkInNewWindowDirective } from './olinw.directive';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { RouterModule, Routes } from '@angular/router';
import { AppComponent } from './app.component';
const appRoutes: Routes = [
{ path: '', pathMatch: 'full', component: AppDefaultComponent },
{ path: 'home', component: AppComponent },
{ path: 'about', component: AppAboutComponent },
{ path: '**', component: PageNotFoundComponent }
];
@NgModule({
declarations: [
AppComponent, AppAboutComponent, AppDefaultComponent, PageNotFoundComponent, OpenLinkInNewWindowDirective
],
imports: [
BrowserModule,
FormsModule,
HttpModule,
RouterModule.forRoot(appRoutes)
],
providers: [{ provide: Window, useValue: window }],
bootstrap: [AppComponent]
})
export class AppModule { }
First link opens in new Window, second one will not:
<h1>
{{title}}
<ul>
<li><a routerLink="/main/home" routerLinkActive="active" olinw007> OLNW</a></li>
<li><a routerLink="/main/home" routerLinkActive="active"> OLNW - NOT</a></li>
</ul>
<div style="background-color:#eee;">
<router-outlet></router-outlet>

Tada! ..and you are welcome =)

Do you mean Project Explorer? Click 'Project' tab on the left edge of Android Studio.
Change android:stretchColumns

Value 0
means stretch the first column. Value 1
means stretch the second column and so on.
Value *
means stretch all the columns.
The user comments on the array_unique() documentation have many solutions to this. Here is one of them:
kenrbnsn at rbnsn dot com
27-Sep-2005 12:09Yet another Array_Unique for multi-demensioned arrays. I've only tested this on two-demensioned arrays, but it could probably be generalized for more, or made to use recursion.
This function uses the serialize, array_unique, and unserialize functions to do the work.
function multi_unique($array) { foreach ($array as $k=>$na) $new[$k] = serialize($na); $uniq = array_unique($new); foreach($uniq as $k=>$ser) $new1[$k] = unserialize($ser); return ($new1); }
This is from http://ca3.php.net/manual/en/function.array-unique.php#57202.
Firebug is great, but Safari provides its own built-in development tools.
If you haven't already tried Safari's development kit, go to Safari-->Preferences-->Advanced, and check the box next to "Show Develop menu in menu bar".
Once you have the Develop menu enabled, you can use the Web Inspector to get a lot of the same functionality that Firebug provides.
You need to import @angular/forms dependency to your module.
if you are using npm, install the dependency :
npm install @angular/forms --save
Import it to your module :
import {FormsModule} from '@angular/forms';
@NgModule({
imports: [.., FormsModule,..],
declarations: [......],
bootstrap: [......]
})
And if you are using SystemJs for loading modules
'@angular/forms': 'node_modules/@angular/forms/bundles/forms.umd.js',
Now you can use [(ngModel)] for two ways databinding.
Not sure what you meant, but you can permanently turn showing whitespaces on and off in Settings -> Editor -> General -> Appearance -> Show whitespaces
.
Also, you can set it for a current file only in View -> Active Editor -> Show WhiteSpaces
.
Edit:
Had some free time since it looks like a popular issue, I had written a plugin to inspect the code for such abnormalities. It is called Zero Width Characters locator and you're welcome to give it a try.
The difference is ternary operator
return condition ? someData : Promise.reject(new Error('not OK'))
return condition ? someData : throw new Error('not OK')
Instead of using interop you can use the .NET FileStream class methods Lock and Unlock:
FileStream.Lock http://msdn.microsoft.com/en-us/library/system.io.filestream.lock.aspx
FileStream.Unlock http://msdn.microsoft.com/en-us/library/system.io.filestream.unlock.aspx
The way to do this using the Extention Methods, instead of the linq query syntax would be like this:
var results = workOrders.Join(plans,
wo => wo.WorkOrderNumber,
p => p.WorkOrderNumber,
(order,plan) => new {order.WorkOrderNumber, order.WorkDescription, plan.ScheduledDate}
);
For Disable Right Click Option
<script type="text/javascript">
var message="Function Disabled!";
function clickIE4(){
if (event.button==2){
alert(message);
return false;
}
}
function clickNS4(e){
if (document.layers||document.getElementById&&!document.all){
if (e.which==2||e.which==3){
alert(message);
return false;
}
}
}
if (document.layers){
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=clickNS4;
}
else if (document.all&&!document.getElementById){
document.onmousedown=clickIE4;
}
document.oncontextmenu=new Function("alert(message);return false")
</script>
Here's a full screen version of that image, below
This will show your query results as comma-delimited text.

Even though a bit old thread, for those who still looking for the differences:
Aside from layout (space) taken in Hidden and not taken in Collapsed, there is another difference.
If we have custom controls inside this 'Collapsed' main control, the next time we set it to Visible, it will "load" all custom controls. It will not pre-load when window is started.
As for 'Hidden', it will load all custom controls + main control which we set as hidden when the "window" is started.
function isEqual(a) {
if (arrayData.length > 0) {
for (var i in arrayData) {
if (JSON.stringify(arrayData[i]) === JSON.stringify(a)) {
alert("Ya existe un registro con esta informacion");
return false;
}
}
}
}
Based on this Connect feedback I fixed it by closing all opened documents and restarting Visual Studio. I use Visual Studio 2015.
Try this:
<?php /* the php */ ?>
<?php
if ($_POST['submit']) {
// must work
echo $_POST['contact_list'];
};
?>
<?php /* and the html */ ?>
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>teszt</title>
</head>
<body>
<form method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
<textarea id="contact_list" name="contact_list"></textarea>
<input type="submit" name="submit" value="Send" id="submit"/>
</form>
</body>
</html>
I also had a requirement something similar to it. I wanted to have a container in the center of the screen and inside the container there are many views. Following is the xml layout code. Here i'm using nested constraint layout to create container in the center of the screen.

Here is the screenshot of the layout
Other solution is to remove the nested constraint layout and add constraint_vertical_bias = 0.5 attribute to the top element in the center of layout. I think this is called as chaining of views.

As I found the best approach to access application settings variables in a systematic way by making a wrapper class over System.Configuration as below
public class BaseConfiguration
{
protected static object GetAppSetting(Type expectedType, string key)
{
string value = ConfigurationManager.AppSettings.Get(key);
try
{
if (expectedType == typeof(int))
return int.Parse(value);
if (expectedType == typeof(string))
return value;
throw new Exception("Type not supported.");
}
catch (Exception ex)
{
throw new Exception(string.Format("Config key:{0} was expected to be of type {1} but was not.",
key, expectedType), ex);
}
}
}
Now we can access needed settings variables by hard coded names using another class as below:
public class ConfigurationSettings:BaseConfiguration
{
#region App setting
public static string ApplicationName
{
get { return (string)GetAppSetting(typeof(string), "ApplicationName"); }
}
public static string MailBccAddress
{

\33[2K
erases the entire line your cursor is currently on
\033[A
moves your cursor up one line, but in the same column i.e. not to the start of the line
\r
brings your cursor to the beginning of the line (r is for carriage return N.B. carriage returns do not include a newline so cursor remains on the same line) but does not erase anything
In xterm specifically, I tried the replies mentioned above and the only way I found to erase the line and start again at the beginning is the sequence (from the comment above posted by @Stephan202 as well as @vlp and @mantal) \33[2K\r
On an implementation note, to get it to work properly for example in a countdown scenario since I wasn't using a new line character '\n'
at the end of each fprintf()
, so I had to fflush()
the stream each time (to give you some context, I started xterm using a fork on a linux machine without redirecting stdout, I was just writing to the buffered FILE pointer fdfile
with a non-blocking file descriptor I had sitting on the pseudo terminal address which in my case was /dev/pts/21
):
fprintf(fdfile, "\33[2K\rT minus %d seconds...", i);
fflush(fdfile);
Note that I used both the \33[2K sequence to erase the line followed by the \r
carriage return sequence to reposition the cursor at the beginning of the line. I had to fflush()
after each fprintf()
because I don't have a new line character at the end '\n'
. The same result without needing fflush() would require the additional sequence to go up a line:
fprintf(fdfile, "\033[A\33[2K\rT minus %d seconds...\n", i);
Note that if you have something on the line immediately above the line you want to write on, it will get over-written with the first fprintf(). You would have to leave an extra line above to allow for the first movement up one line:
i = 3;
fprintf(fdfile, "\nText to keep\n");
fprintf(fdfile, "Text to erase****************************\n");
while(i > 0) { // 3 second countdown
fprintf(fdfile, "\033[A\33[2KT\rT minus %d seconds...\n", i);
i--;
sleep(1);
}
Make sure right depency is selected. File > Project Structure
Select your project and navigate to Dependencies tab. Select right dependancy from dropdown or create new.
just use getCheckedRadioButtonId() function to determine wether if anything is checked, if -1 is return, you can avoid toast appear
Just put the following below your form. Make sure your input fields are required
.
<script>
var forms = document.getElementsByTagName('form');
for (var i = 0; i < forms.length; i++) {
forms[i].noValidate = true;
forms[i].addEventListener('submit', function(event) {
if (!event.target.checkValidity()) {
event.preventDefault();
alert("Please complete all fields and accept the terms.");
}
}, false);
}
</script>
You do not want to have the log4j.properties packaged with your project deployable -- that is a bad idea, as other posters have mentioned.
Find the root Tomcat installation that Eclipse is pointing to when it runs your application, and add the log4j.properties file in the proper place there. For Tomcat 7, the right place is
${TOMCAT_HOME}/lib
As was in my case if your sql is generated by concatenating or uses converts then sql at execute need to be prefixed with letter N as below
e.g.
Exec N'Select bla..'
the N defines string literal is unicode.
If you want this to be highlighted depending upon the page your user is on then do this:
To auto-highlight your current navigation, first label your body tags with an ID or class that matches the section of the site (usually a directory) that the page is in.
<body class="ab">
We label all files in the "/about/" directory with the "ab" class. Note that we use a class here to label the body tags. We found that using an ID in the body did not work consistently in some older browsers. Next we label our menu items so we can target them individually thus:
<div id="n"> <a class="b" id="hm"
href="/">Home</a> ... <a class="b"
id="ab" href="/about/">About</a> ...
</div>
Note that we use the "b"utton class to label menu items as buttons and an ID ("ab") to label each unique menu item (in this case about). Now all we need is a CSS selector that matches up the body label with the appropriate menu label like this:
body.ab #n #ab, body.ab #n #ab
a{color:#333;background:#dcdcdc;text-decoration:none;}
This code effectively highlights the "About" menu item and makes it appear dark gray. When you label the rest of the site and menu items, you'll end up with a grouped selector that looks something like this:
body.hm #n #hm, body.hm #n #hm a,
body.sm #n #sm, body.sm #n #sm a,
body.is #n #is, body.is #n #is a,
body.ab #n #ab, body.ab #n #ab a,
body.ct #n #ct, body.ct #n #ct
a{color:#333;background:#dcdcdc;text-decoration:none;}
For example when the user navigates to the sitemap section the .sm classed body tag matches the #sm menu option and triggers the CSS highlight of the "Sitemap" in the navigation bar.
This should work:
IDTSVariables100 vars = null;
VariableDispenser.LockForRead("System::TaskName");
VariableDispenser.GetVariables(vars);
string TaskName = vars("System::TaskName").Value.ToString();
vars.Unlock();
Your initial code lacks call of the GetVariables() method.
You do not need to create an element like the < br > tag, or any other spacer tag. What you should do is apply a style to the element that needs spacing around it.
Let's say the element you want to have space around is a DIV tag called "myelement".
<div class="myelement">
I am content that needs spacing around it!
</div>
This is the style you would need to use.
.myelement {
clear:left;
height:25px;
margin: 20px; // See below for explanation of this
}
This is the style you can use to better understand CSS for beginners
.myelement {
clear:left;
height:25px;
margin-top:20px;
margin-right:20px;
margin-bottom:20px;
margin-left:20px;
}
Also, avoid using the height: CSS property until you know what you are doing. You will run into some issues when using height that are harder to troubleshoot as a beginner.
If you only care about the conflict resolution and not about keeping the commit history, the following method should work. Say you want to merge a.py b.py
from BRANCHA
into BRANCHB
. First, make sure any changes in BRANCHB
are either committed or stashed away, and that there are no untracked files. Then:
git checkout BRANCHB
git merge BRANCHA
# 'Accept' all changes
git add .
# Clear staging area
git reset HEAD -- .
# Stash only the files you want to keep
git stash push a.py b.py
# Remove all other changes
git add .
git reset --hard
# Now, pull the changes
git stash pop
git
won't recognize that there are conflicts in a.py b.py
, but the merge conflict markers are there if there were in fact conflicts. Using a third-party merge tool, such as VSCode, one will be able to resolve conflicts more comfortably.
Why not just use the following.
System.IO.Path.Combine(rootUrl, subPath).Replace(@"\", "/")
SHOW CREATE TABLE <tablename>\G
will format it much nicer compared to the output of
SHOW CREATE TABLE <tablename>;
The \G
trick is also useful to remember for many other queries/commands.
It is not possible with ALTER statement. If you wish to have the columns in a specific order, you will have to create a newtable, use INSERT INTO newtable (col-x,col-a,col-b) SELECT col-x,col-a,col-b FROM oldtable to transfer the data from the oldtable to the newtable, delete the oldtable and rename the newtable to the oldtable name.
This is not necessarily recommended because it does not matter which order the columns are in the database table. When you use a SELECT statement, you can name the columns and have them returned to you in the order that you desire.
I definitely prefer the format
method more, as it is very flexible and can be easily extended to your custom classes by defining __format__
or the str
or repr
representations. For the sake of keeping it simple, i am using print
in the following examples, which can be replaced by sys.stdout.write
.
Simple Examples: alignment / filling
#Justify / ALign (left, mid, right)
print("{0:<10}".format("Guido")) # 'Guido '
print("{0:>10}".format("Guido")) # ' Guido'
print("{0:^10}".format("Guido")) # ' Guido '
We can add next to the align
specifies which are ^
, <
and >
a fill character to replace the space by any other character
print("{0:.^10}".format("Guido")) #..Guido...
Multiinput examples: align and fill many inputs
print("{0:.<20} {1:.>20} {2:.^20} ".format("Product", "Price", "Sum"))
#'Product............. ...............Price ........Sum.........'
Advanced Examples
If you have your custom classes, you can define it's str
or repr
representations as follows:
class foo(object):
def __str__(self):
return "...::4::.."
def __repr__(self):
return "...::12::.."
Now you can use the !s
(str) or !r
(repr) to tell python to call those defined methods. If nothing is defined, Python defaults to __format__
which can be overwritten as well.
x = foo()
print "{0!r:<10}".format(x) #'...::12::..'
print "{0!s:<10}".format(x) #'...::4::..'

Double click the file.txt
, then save it, command + s
, that worked in my case. Also, make sure the file.txt
is saved in the project folder.
If that does not work.
PrintWriter pw = new PrintWriter(new File("file.txt"));
pw.println("hello world"); // to test if it works.
First check with dmesg | grep tty
if system recognize your adapter.
Then try to run minicom with sudo minicom -s
, go to "Serial port setup" and change the first line to /dev/ttyUSB0
.
Don't forget to save config as default with "Save setup as dfl". It works for me on Ubuntu 11.04 on VirtualBox.
Solved it as follows,
in CSS
#my{
zoom: 100%;
}
Now, it loads in 100% zoom by default. Tested it by giving 290% zoom and it loaded by that zoom percentage on default, it's upto the user if he wants to change zoom.
Though this is not the best way to do it, there is another effective solution
Check the page code of stack over flow, even they have buttons and they use un ordered lists to solve this problem.
In my case i uninstalled application from phone it after that the problem began but, the below command worked for me.
Execute below command in terminal/cmd
adb uninstall <package_name>
package_name something like com.example.applicationname Then, try to reinstall the application. It should work.
I figured it out. Need to use echo in PHP instead of return.
<?php
$output = some_function();
echo $output;
?>
And the jQ:
success: function(data) {
doSomething(data);
}
Set decoding to true
Your decoding is not set to true. If you don't have access to set the source to true. The code below will fix it for you.
$WorkingArray = json_decode(json_encode($data),true);
We use
SELECT * FROM MyTable WHERE ISNULL(MyColumn, ' ') = ' ';
to return all rows where MyColumn is NULL or all rows where MyColumn is an empty string. To many an "end user", the NULL vs. empty string issue is a distinction without a need and point of confusion.
use this and pass connection object :
SqlCommand cmd=new SqlCommand ("insert into time(project,iteration)values('"+this .name1 .SelectedValue +"','"+this .iteration .SelectedValue +"')",conn);
The IF statement has these forms in PL/SQL
:
IF THEN
IF THEN ELSE
IF THEN ELSIF
You have used elseif
which in terms of PL/SQL is wrong. That need to be replaced with ELSIF
.
So your code should appear like this.
declare
var_number number;
begin
var_number := 10;
if var_number > 100 then
dbms_output.put_line(var_number ||' is greater than 100');
--elseif should be replaced with elsif
elsif var_number < 100 then
dbms_output.put_line(var_number ||' is less than 100');
else
dbms_output.put_line(var_number ||' is equal to 100');
end if;
end;
You can do this:
gdb --args path/to/executable -every -arg you can=think < of
The magic bit being --args
.
Just type run
in the gdb command console to start debugging.
This might help you out:
Sub SelectFolder()
Dim diaFolder As FileDialog
Dim Fname As String
Set diaFolder = Application.FileDialog(msoFileDialogFolderPicker)
diaFolder.AllowMultiSelect = False
diaFolder.Show
Fname = diaFolder.SelectedItems(1)
ActiveSheet.Range("B9") = Fname
End Sub
You don't really have to call the __init__
methods of the base class(es), but you usually want to do it because the base classes will do some important initializations there that are needed for rest of the classes methods to work.
For other methods it depends on your intentions. If you just want to add something to the base classes behavior you will want to call the base classes method additionally to your own code. If you want to fundamentally change the behavior, you might not call the base class' method and implement all the functionality directly in the derived class.
Try this,
int dialogButton = JOptionPane.YES_NO_OPTION;
int dialogResult = JOptionPane.showConfirmDialog(this, "Your Message", "Title on Box", dialogButton);
if(dialogResult == 0) {
System.out.println("Yes option");
} else {
System.out.println("No Option");
}
Note the comma in your string: "1,07". DecimalFormat
uses a locale-specific separator string, while Double.parseDouble()
does not. As you happen to live in a country where the decimal separator is ",", you can't parse your number back.
However, you can use the same DecimalFormat
to parse it back:
DecimalFormat df=new DecimalFormat("0.00");
String formate = df.format(value);
double finalValue = (Double)df.parse(formate) ;
But you really should do this instead:
double finalValue = Math.round( value * 100.0 ) / 100.0;
Note: As has been pointed out, you should only use floating point if you don't need a precise control over accuracy. (Financial calculations being the main example of when not to use them.)
The return statement only makes sense inside functions:
def foo():
while True:
return False
The exclusion pattern should be case-insensitive, so you shouldn't have to specify every case for the exclusion.
That said, the -Exclude
parameter accepts an array of strings, so as long as you define $archive
as such, you should be set.
$archive = ("*archive*","*Archive*","*ARCHIVE*");
You also should drop the trailing asterisk from $folder
- since you're specifying -recurse
, you should only need to give the top-level folder.
$folder = "T:\Drawings\Design\"
Fully revised script. This also changes how you detect whether you've found a directory, and skips the Foreach-Object
because you can just pull the property directly & dump it all to the file.
$folder = "T:\Drawings\Design\";
$raw_txt = "T:\Design Projects\Design_Admin\PowerShell\raw.txt";
$search_pro = "T:\Design Projects\Design_Admin\PowerShell\search.pro";
$archive = ("*archive*","*Archive*","*ARCHIVE*");
Get-ChildItem -Path $folder -Exclude $archive -Recurse | where {$_.PSIsContainer} | select-Object -expandproperty FullName |out-file $search_pro
I've solved this error downloading the executable file for python 3.7. I've had downloaded the embeddeable version and got that error. Now it works! :D
The listed return type of the method is Task<string>
. You're trying to return a string
. They are not the same, nor is there an implicit conversion from string to Task<string>
, hence the error.
You're likely confusing this with an async
method in which the return value is automatically wrapped in a Task
by the compiler. Currently that method is not an async method. You almost certainly meant to do this:
private async Task<string> methodAsync()
{
await Task.Delay(10000);
return "Hello";
}
There are two key changes. First, the method is marked as async
, which means the return type is wrapped in a Task
, making the method compile. Next, we don't want to do a blocking wait. As a general rule, when using the await
model always avoid blocking waits when you can. Task.Delay
is a task that will be completed after the specified number of milliseconds. By await
-ing that task we are effectively performing a non-blocking wait for that time (in actuality the remainder of the method is a continuation of that task).
If you prefer a 4.0 way of doing it, without using await
, you can do this:
private Task<string> methodAsync()
{
return Task.Delay(10000)
.ContinueWith(t => "Hello");
}
The first version will compile down to something that is more or less like this, but it will have some extra boilerplate code in their for supporting error handling and other functionality of await
we aren't leveraging here.
If your Thread.Sleep(10000)
is really meant to just be a placeholder for some long running method, as opposed to just a way of waiting for a while, then you'll need to ensure that the work is done in another thread, instead of the current context. The easiest way of doing that is through Task.Run
:
private Task<string> methodAsync()
{
return Task.Run(()=>
{
SomeLongRunningMethod();
return "Hello";
});
}
Or more likely:
private Task<string> methodAsync()
{
return Task.Run(()=>
{
return SomeLongRunningMethodThatReturnsAString();
});
}
Try this library:
https://github.com/avast/android-styled-dialogs
It's based on DialogFragments
instead of AlertDialogs
(like the one from @afollestad). The main advantage: Dialogs don't dismiss after rotation and callbacks still work.
Again if you don't want to use bodyParser, the following works:
var express = require('express');
var http = require('http');
var app = express();
app.use(express.static('./public'));
app.configure(function(){
app.use(express.methodOverride());
app.use(express.multipart({
uploadDir: './uploads',
keepExtensions: true
}));
});
app.use(app.router);
app.get('/upload', function(req, res){
// Render page with upload form
res.render('upload');
});
app.post('/upload', function(req, res){
// Returns json of uploaded file
res.json(req.files);
});
http.createServer(app).listen(3000, function() {
console.log('App started');
});
MySQL has an undocumented syntax to sort nulls last. Place a minus sign (-) before the column name and switch the ASC to DESC:
SELECT * FROM tablename WHERE visible=1 ORDER BY -position DESC, id DESC
It is essentially the inverse of position DESC
placing the NULL values last but otherwise the same as position ASC
.
A good reference is here http://troels.arvin.dk/db/rdbms#select-order_by
Based on zhigang's answer, this avoids self-killing:
init_killtree() {
local pid=$1 child
for child in $(pgrep -P $pid); do
init_killtree $child
done
[ $pid -ne $$ ] && kill -kill $pid
}
For a Spark execution in pyspark two components are required to work together:
pyspark
python packageWhen launching things with spark-submit or pyspark, these scripts will take care of both, i.e. they set up your PYTHONPATH, PATH, etc, so that your script can find pyspark, and they also start the spark instance, configuring according to your params, e.g. --master X
Alternatively, it is possible to bypass these scripts and run your spark application directly in the python interpreter likepython myscript.py
. This is especially interesting when spark scripts start to become more complex and eventually receive their own args.
getOrCreate()
from the builder object.Your script can therefore have something like this:
from pyspark.sql import SparkSession
if __name__ == "__main__":
if spark_main_opts:
# Set main options, e.g. "--master local[4]"
os.environ['PYSPARK_SUBMIT_ARGS'] = spark_main_opts + " pyspark-shell"
# Set spark config
spark = (SparkSession.builder
.config("spark.checkpoint.compress", True)
.config("spark.jars.packages", "graphframes:graphframes:0.5.0-spark2.1-s_2.11")
.getOrCreate())
I had a similar issue with Spring 4.x using @RestController. Two different packages had a class with the same name...
package com.x.catalog
@RestController
public class TextureController {
...
package com.x.cms
@RestController
public class TextureController {
...
The fix was easy...
package com.x.catalog
@RestController("CatalogTextureController")
public class TextureController {
...
package com.x.cms
@RestController("CMSTextureController")
public class TextureController {
...
The problem seems to be that the annotation gets autowired and takes the class name by default. Giving it an explicit name in the @RestController annotation allows you to keep the class names.
This comes in useful when you have global variables. You declare the existence of global variables in a header, so that each source file that includes the header knows about it, but you only need to “define” it once in one of your source files.
To clarify, using extern int x;
tells the compiler that an object of type int
called x
exists somewhere. It's not the compilers job to know where it exists, it just needs to know the type and name so it knows how to use it. Once all of the source files have been compiled, the linker will resolve all of the references of x
to the one definition that it finds in one of the compiled source files. For it to work, the definition of the x
variable needs to have what's called “external linkage”, which basically means that it needs to be declared outside of a function (at what's usually called “the file scope”) and without the static
keyword.
#ifndef HEADER_H
#define HEADER_H
// any source file that includes this will be able to use "global_x"
extern int global_x;
void print_global_x();
#endif
#include "header.h"
// since global_x still needs to be defined somewhere,
// we define it (for example) in this source file
int global_x;
int main()
{
//set global_x here:
global_x = 5;
print_global_x();
}
#include <iostream>
#include "header.h"
void print_global_x()
{
//print global_x here:
std::cout << global_x << std::endl;
}
This applies to "IntelliJ IDEA-2019.2.4" on Mac.
This is an addition to Josh's answer.
You can also keep the values of other variables while filtering out duplicated rows in data.table
Example:
library(data.table)
#create data table
dt <- data.table(
V1=LETTERS[c(1,1,1,1,2,3,3,5,7,1)],
V2=LETTERS[c(2,3,4,2,1,4,4,6,7,2)],
V3=c(1),
V4=c(2) )
> dt
# V1 V2 V3 V4
# A B 1 2
# A C 1 2
# A D 1 2
# A B 1 2
# B A 1 2
# C D 1 2
# C D 1 2
# E F 1 2
# G G 1 2
# A B 1 2
# set the key to all columns
setkey(dt)
# Get Unique lines in the data table
unique( dt[list(V1, V2), nomatch = 0] )
# V1 V2 V3 V4
# A B 1 2
# A C 1 2
# A D 1 2
# B A 1 2
# C D 1 2
# E F 1 2
# G G 1 2
Alert: If there are different combinations of values in the other variables, then your result will be
unique combination of V1 and V2
Got the solution
Go to references right click the desired dll you will get option "Embed Interop Types" to "False" or "True".
I found this script somewhere. I don't remember where, but it works for me:

Reported by @davidpbr ConstraintLayout
performance
I made two similar 7-child layouts, one each with a parent ConstraintLayout
and RelativeLayout
.
Based on Android Studio method tracing tool, it appears the ConstraintLayout
spends more time in onMeasure and performs additional work in onFinishInflate
.
Library used (support-v4
, appcompat-v7
…):
com.android.support.constraint:constraint-layout:1.0.0-alpha1

Just download "node.exe" from http://nodejs.org/dist/, select your favorite "node.js" version or take the latest. You can also take 64-bits version from "x64" sub-directory.
Then, go to http://nodejs.org/dist/npm/ to retrieve Zip-archive of your favorite "npm" version (recommanded : 1.4.10
). Extract the archive along "node.exe".
Finally, it is recommanded to add "node.js" directory to the PATH for convenience.
EDIT: I recommande to update npm using npm install npm -g
because versions provided by nodejs.org are very old.
If you want to keep original npm version, don't put npm alongside "node.exe"
. Just create a directory and use the same command with "global" flag, then copy .\node_modules\.bin\npm.cmd
to the new directory :
mkdir c:\app\npm\_latest
cd c:\app\npm\_latest
<NPM_ORIGINAL_PATH>\npm install npm
cp node_modules\.bin\npm.cmd npm.cmd
Finally change your PATH to use c:\app\npm\_latest
I encountered the same credential prompting issue, and did a quick search and nothing on the internet would fix it. It took some time to find the problem, a silly one.
In IIS -> Advance Setting -> Physical Path Credential (is empty)
As soon as i added a machine ID (domain/user) that has access to the VM/server, the password prompting would stop.
Hope this helps
Explanation with an example:
Consider you have a game (iso) image in your computer.
When you run
(mount your image as a virtual drive), a virtual drive is created with all the game contents in the virtual drive and the game installation file is automatically launched. [Running your docker image - creating a container and then starting it.]
But when you stop
(similar to docker stop) it, the virtual drive still exists but stopping all the processes. [As the container exists till it is not deleted]
And when you do start
(similar to docker start), from the virtual drive the games files start its execution. [starting the existing container]
In this example - The game image is your Docker image and virtual drive is your container.
MySQL is most likely in STRICT
mode, which isn't necessarily a bad thing, as you'll identify bugs/issues early and not just blindly think everything is working as you intended.
Change the column to allow null:
ALTER TABLE `x` CHANGE `display_name` `display_name` TEXT NULL
or, give it a default value as empty string:
ALTER TABLE `x` CHANGE `display_name` `display_name` TEXT NOT NULL DEFAULT ''
You can move your files to other folder and then pull whole folder.
adb shell mkdir /sdcard/tmp adb shell mv /sdcard/mydir/*.jpg /sdcard/tmp # move your jpegs to temporary dir adb pull /sdcard/tmp/ # pull this directory (be sure to put '/' in the end) adb shell mv /sdcard/tmp/* /sdcard/mydir/ # move them back adb shell rmdir /sdcard/tmp # remove temporary directory
First you need to separate your class from the further extensions ex you cannot extend AddAddressComponent.defaultProps
within the class
instead move it outside.
I will also recommend you to read about the Constructor and React's lifecycle: see Component Specs and Lifecycle
Here is what you want:
import PropTypes from 'prop-types';
class AddAddressComponent extends React.Component {
render() {
let { provinceList, cityList } = this.props;
if(cityList === undefined || provinceList === undefined){
console.log('undefined props');
}
}
}
AddAddressComponent.contextTypes = {
router: PropTypes.object.isRequired
};
AddAddressComponent.defaultProps = {
cityList: [],
provinceList: [],
};
AddAddressComponent.propTypes = {
userInfo: PropTypes.object,
cityList: PropTypes.array.isRequired,
provinceList: PropTypes.array.isRequired,
}

to a variable and pass that variable to end
:
$tmp = explode('.', $file_name);
$file_extension = end($tmp);
The problem is, that end
requires a reference, because it modifies the internal representation of the array (i.e. it makes the current element pointer point to the last element).
The result of explode('.', $file_name)
cannot be turned into a reference. This is a restriction in the PHP language, that probably exists for simplicity reasons.
Used this link, stackoverflow.com/a/17380697/1725764, by Hashem Qolami at the original posts' comments and used display:inline-blocks instead of floats. Fixes borders if the table has the class 'table-bordered' also.
table.scroll {
width: 100%;
&.table-bordered {
td, th {
border-top: 0;
border-right: 0;
}
th {
border-bottom-width: 1px;
}
td:first-child,
th:first-child {
border-right: 0;
border-left: 0;
}
}
tbody {
height: 200px;
overflow-y: auto;
overflow-x: hidden;
}
tbody, thead {
display: block;
}
tr {
width: 100%;
display: block;
}
th, td {
display: inline-block;
}
td {
height: 46px; //depends on your site
}
}
Then just add the widths of the td and th
table.table-prep {
tr > td.type,
tr > th.type{
width: 10%;
}
tr > td.name,
tr > th.name,
tr > td.notes,
tr > th.notes,
tr > td.quantity,
tr > th.quantity{
width: 30%;
}
}
The type char is a primitive -- not an object -- so it cannot be dereferenced
Dereferencing is the process of accessing the value referred to by a reference. Since a char is already a value (not a reference), it can not be dereferenced.
use Character
class:
if(Character.isLetter(c)) {
Chrome on Android makes it possible to use the Chrome developer tools on the desktop to inspect the HTML that was loaded from the Chrome application on the Android device.
See: https://developers.google.com/chrome-developer-tools/docs/remote-debugging
I am late here but I resolved same kind of problem in this way that is simple and easy.
<select ng-model="blisterPackTemplateSelected" ng-change="selectedBlisterPack(blisterPackTemplateSelected)">
<option value="">Select Account</option>
<option ng-repeat="blisterPacks in blisterPackTemplates" value="{{blisterPacks.id}}">{{blisterPacks.name}}</option>
and the function for ng-change is as follows;
$scope.selectedBlisterPack= function (value) {
console.log($scope.blisterPackTemplateSelected);
};
Check if the activity isFinishing()
before showing the fragment.
Example:
if(!isFinishing()) {
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
DummyFragment dummyFragment = DummyFragment.newInstance();
ft.add(R.id.dummy_fragment_layout, dummyFragment);
ft.commitAllowingStateLoss();
}
When using NOT IN, you should also consider NOT EXISTS, which handles the null cases silently. See also PostgreSQL Wiki
SELECT mac, creation_date
FROM logs lo
WHERE logs_type_id=11
AND NOT EXISTS (
SELECT *
FROM consols nx
WHERE nx.mac = lo.mac
);
Angular introduced $watchGroup
in version 1.3 using which we can watch multiple variables, with a single $watchGroup
block
$watchGroup
takes array as first parameter in which we can include all of our variables to watch.
$scope.$watchGroup(['var1','var2'],function(newVals,oldVals){
console.log("new value of var1 = " newVals[0]);
console.log("new value of var2 = " newVals[1]);
console.log("old value of var1 = " oldVals[0]);
console.log("old value of var2 = " oldVals[1]);
});
You can use linking property <Text style={{color: 'skyblue'}} onPress={() => Linking.openURL('http://yahoo.com')}> Yahoo
Build.SERIAL
can be empty or sometimes return a different value (proof 1, proof 2) than what you can see in your device's settings.
If you want a more complete and robust solution, I've compiled every possible solution I could found in a single gist. Here's a simplified version of it :
public static String getSerialNumber() {
String serialNumber;
try {
Class<?> c = Class.forName("android.os.SystemProperties");
Method get = c.getMethod("get", String.class);
serialNumber = (String) get.invoke(c, "gsm.sn1");
if (serialNumber.equals(""))
serialNumber = (String) get.invoke(c, "ril.serialnumber");
if (serialNumber.equals(""))
serialNumber = (String) get.invoke(c, "ro.serialno");
if (serialNumber.equals(""))
serialNumber = (String) get.invoke(c, "sys.serialnumber");
if (serialNumber.equals(""))
serialNumber = Build.SERIAL;
// If none of the methods above worked
if (serialNumber.equals(""))
serialNumber = null;
} catch (Exception e) {
e.printStackTrace();
serialNumber = null;
}
return serialNumber;
}
I try to update the gist regularly whenever I can test on a new device or Android version. Contributions are welcome too.
yes is possible to run your android emulator without have a hardware accelerator. In fact to do that, you need to open your android virtual device. When you reached to system image configure, it suggest you which version of android image you want to use. Whatever version of android system image that you select,you need to make sure that,ABI is armeabi-v7a and, you target is System image ameabi-v7a with google APIs. And then complete the rest of task and check out your emulator.
Following code is working for me.
Usings:
using System.IO;
using System.Net;
using Newtonsoft.Json.Linq;
Code:
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
using (Stream responseStream = response.GetResponseStream())
{
using (StreamReader responseReader = new StreamReader(responseStream))
{
string json = responseReader.ReadToEnd();
string data = JObject.Parse(json)["id"].ToString();
}
}
}
//json = {"kind": "ALL", "id": "1221455", "longUrl": "NewURL"}
try using the permission of WRITE_EXTERNAL_STORAGE You should use that whether there is an external card or not.
This works well for me:
path = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_MOVIES);
File file = new File(path, "/" + fname);
and places my files in the appropriate folder
Specific use case for emplace_back
: If you need to create a temporary object which will then be pushed into a container, use emplace_back
instead of push_back
. It will create the object in-place within the container.
Notes:
push_back
in the above case will create a temporary object and move it
into the container. However, in-place construction used for emplace_back
would be more
performant than constructing and then moving the object (which generally involves some copying).emplace_back
instead of push_back
in all the cases without much issue. (See exceptions)I've got a solution that's pretty simple to implement.
Make a temporary class just to wrap the list object and later call the value from the class.
Here's a practical example:
df = pd.DataFrame([
{'a': 1},
{'a': 2},
{'a': 3},
])
df.loc[:, 'b'] = [
[1,2,4,2,],
[1,2,],
[4,5,6]
] # This works. Because the list has the same length as the rows of the dataframe
df.loc[:, 'c'] = [1,2,4,5,3] # This does not work.
>>> ValueError: Must have equal len keys and value when setting with an iterable
## To force pandas to have list as value in each cell, wrap the list with a temporary class.
class Fake(object):
def __init__(self, li_obj):
self.obj = li_obj
df.loc[:, 'c'] = Fake([1,2,5,3,5,7,]) # This works.
df.c = df.c.apply(lambda x: x.obj) # Now extract the value from the class. This works.
Creating a fake class to do this might look like a hassle but it can have some practical applications. For an example you can use this with apply
when the return value is list.
Pandas would normally refuse to insert list into a cell but if you use this method, you can force the insert.
So..it was SSL problem. Whatever I was doing was absolutely correct. Only that I was not using the ssl option. So I added "-Usessl true" to my original command and it worked.
Better way is to use TryParse:
Int32 _userInput;
if(Int32.TryParse (Console.Readline(), out _userInput) {// do the stuff on userInput}
I have found one related behaviour that may help (sounds like your specific problem runs deeper though):
Flash checks whether a source file needs recompiling by looking at timestamps. If its compiled version is older than the source file, it will recompile. But it doesn't check whether the compiled version was generated from the same source file or not.
Specifically, if you have your actionscript files under version control, and you Revert a change, the reverted file will usually have an older timestamp, and Flash will ignore it.
This needs to be done on the server-side, where the cookie was issued.
cordova achieve this. I still can not figure out how cordova did. It does not even go through shouldInterceptRequest.
Later I found out that the key to load any file from local is: myWebView.getSettings().setAllowUniversalAccessFromFileURLs(true);
And when you want to access any http resource, the webview will do checking with OPTIONS method, which you can grant the access through WebViewClient.shouldInterceptRequest by return a response, and for the following GET/POST method, you can just return null.
test equals with an empty string and null in the same conditional:
if(!"".equals(str) && str != null) {
// do stuff.
}
Does not throws NullPointerException
if str is null, since Object.equals()
returns false if arg is null
.
the other construct str.equals("")
would throw the dreaded NullPointerException
. Some might consider bad form using a String literal as the object upon wich equals()
is called but it does the job.

I had the same problem. Just set the ContentMode of the ImageView that is inside the UIButton.
[[self.itemImageButton imageView] setContentMode: UIViewContentModeScaleAspectFit];
[self.itemImageButton setImage:[UIImage imageNamed:stretchImage] forState:UIControlStateNormal];
Hope this helps.
