If you're using the command console to compile the servlet, then you should include Tomcat's /lib/servlet-api.jar
in the compile classpath.
javac -cp .:/path/to/tomcat/lib/servlet-api.jar com/example/MyServlet.java
(use ;
instead of :
as path separator in Windows)
If you're using an IDE, then you should integrate Tomcat in the IDE and reference it as target runtime in the project. If you're using Eclipse as IDE, see also this for more detail: How do I import the javax.servlet API in my Eclipse project?
You can use reduce
>>> a = 'ZENOVW'
>>> reduce(lambda x,y: x+y, sorted(a))
'ENOVWZ'
You use an implicit operator that converts the string value to a struct value:
public struct MyStruct {
public string s;
public int length;
public static implicit operator MyStruct(string value) {
return new MyStruct() { s = value, length = value.Length };
}
}
Example:
MyStruct myStruct = "Lol";
Console.WriteLine(myStruct.s);
Console.WriteLine(myStruct.length);
Output:
Lol

I don't have Anaconda so the steps I took are:
brew uninstall python3
brew install python3
Your Xcode (10.2) is too outdated. Please update to Xcode 11.3 (or delete it). Xcode can be updated from the App Store.
**So, I deleted Xcode since no update would show, then I reinstalled it.xcode-select --install
after. If you don't.. you'll get an error: The following formula python cannot be installed as binary package and must be built from source. Install the Command Line Tools: xcode-select --install
brew install python3
and it completed successfully.Used this script just to see if it works

I recommend the following syntax for readability.
<? if ($condition): ?>
<p>Content</p>
<? elseif ($other_condition): ?>
<p>Other Content</p>
<? else: ?>
<p>Default Content</p>
<? endif; ?>
Note, omitting php
on the open tags does require that short_open_tags
is enabled in your configuration, which is the default. The relevant curly-brace-free conditional syntax is always enabled and can be used regardless of this directive.
If you will look at package.json
file.
you will see something like this
"start": "http-server -a localhost -p 8000"
This tells start a http-server
at address of localhost
on port 8000
http-server is a node-module.
Update:- Including comment by @Usman, ideally it should be present in your package.json
but if it's not present you can include it in scripts
section.
There's a new way to do this coming in Python 3.4:
from contextlib import suppress
with suppress(Exception):
# your code
Here's the commit that added it: http://hg.python.org/cpython/rev/406b47c64480
And here's the author, Raymond Hettinger, talking about this and all sorts of other Python hotness (relevant bit at 43:30): http://www.youtube.com/watch?v=OSGv2VnC0go
If you wanted to emulate the bare except
keyword and also ignore things like KeyboardInterrupt
—though you usually don't—you could use with suppress(BaseException)
.
Edit: Looks like ignored
was renamed to suppress
before the 3.4 release.
Inspired in this answer I came up with a bit more object-oriented solution.
This is only valid if you're intending to read characters
You can override BufferedReader and implement something like this:
public class SafeBufferedReader extends BufferedReader{
private long millisTimeout;
( . . . )
@Override
public int read(char[] cbuf, int off, int len) throws IOException {
try {
waitReady();
} catch(IllegalThreadStateException e) {
return 0;
}
return super.read(cbuf, off, len);
}
protected void waitReady() throws IllegalThreadStateException, IOException {
if(ready()) return;
long timeout = System.currentTimeMillis() + millisTimeout;
while(System.currentTimeMillis() < timeout) {
if(ready()) return;
try {
Thread.sleep(100);
} catch (InterruptedException e) {
break; // Should restore flag
}
}
if(ready()) return; // Just in case.
throw new IllegalThreadStateException("Read timed out");
}
}
Here's an almost complete example.
I'm returning 0 on some methods, you should change it to -2 to meet your needs, but I think that 0 is more suitable with BufferedReader contract. Nothing wrong happened, it just read 0 chars. readLine method is a horrible performance killer. You should create a entirely new BufferedReader if you actually want to use readLine. Right now, it is not thread safe. If someone invokes an operation while readLines is waiting for a line, it will produce unexpected results
I don't like returning -2 where I am. I'd throw an exception because some people may just be checking if int < 0 to consider EOS. Anyway, those methods claim that "can't block", you should check if that statement is actually true and just don't override'em.

The poor mans compromise solution is to use a simplistic multi signature approach.
For Example the DBA sets the applications database password to a 50 character random string. TAKqWskc4ncvKaJTyDcgAHq82X7tX6GfK2fc386bmNw3muknjU
He or she give half the password to the application developer who then hard codes it into the java binary.
private String pass1 = "TAKqWskc4ncvKaJTyDcgAHq82"
The other half of the password is passed as a command line argument. the DBA gives pass2 to the system support or admin person who either enters it a application start time or puts it into the automated application start up script.
java -jar /myapplication.jar -pass2 X7tX6GfK2fc386bmNw3muknjU
When the application starts it uses pass1 + pass2 and connects to the database.
This solution has many advantages with out the downfalls mentioned.
You can safely put half the password in a command line arguments as reading it wont help you much unless you are the developer who has the other half of the password.
The DBA can also still change the second half of the password and the developer need not have to re-deploy the application.
The source code can also be semi public as reading it and the password will not give you application access.
You can further improve the situation by adding restrictions on the IP address ranges the database will accept connections from.

Note: Preparing XXXHDPI is not needed and also maybe XXHDPI size too because of the repeating areas of 9-patch images. On the other hand, if only Portrait sizes are used the App size could be more less. More pictures mean more space is need.
I think there is no an exact size for the all devices. I use Xperia Z 5". If you develop a crossplatform-webview app you should consider a lot of things (whether screen has softkey navigation buttons or not, etc). Therefore, I think there is only one suitable solution. The solution is to prepare a 9-patch splash screen (find How to design a new splash screen
heading below).
That's it!
Cordova specific code
To be added lines into the config.xml for 9-patch splash screens
<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="6000" />
<platform name="android">
<splash src="res/screen/android/ldpi.9.png" density="ldpi"/>
<splash src="res/screen/android/mdpi.9.png" density="mdpi"/>
<splash src="res/screen/android/hdpi.9.png" density="hdpi"/>
<splash src="res/screen/android/xhdpi.9.png" density="xhdpi"/>
</platform>
To be added lines into the config.xml when using non-9-patch splash screens
<platform name="android">
<splash src="res/screen/android/splash-land-hdpi.png" density="land-hdpi"/>
<splash src="res/screen/android/splash-land-ldpi.png" density="land-ldpi"/>
<splash src="res/screen/android/splash-land-mdpi.png" density="land-mdpi"/>
<splash src="res/screen/android/splash-land-xhdpi.png" density="land-xhdpi"/>
<splash src="res/screen/android/splash-port-hdpi.png" density="port-hdpi"/>
<splash src="res/screen/android/splash-port-ldpi.png" density="port-ldpi"/>
<splash src="res/screen/android/splash-port-mdpi.png" density="port-mdpi"/>
<splash src="res/screen/android/splash-port-xhdpi.png" density="port-xhdpi"/>
</platform>
I would describe a simple way to create proper splash screen using this way. Assume we're designing a 1280dp x 720dp - xhdpi (x-large) screen. I've written for the sake of example the below;
In Photoshop: File -> New in new dialog window set your screens
Width: 720 Pixels Height: 1280 Pixels
I guess the above sizes mean Resolution is 320 Pixels/Inch. But to ensure you can change resolution value to 320 in your dialog window. In this case Pixels/Inch = DPI
Congratulations... You have a 720dp x 1280dp splash screen template.
After you designed your splash screen, if you want to design 9-Patch splash screen, you should insert 1 pixel gap for every side. For this reason you should increase +2 pixel your canvas size's width and height ( now your image sizes are 722 x 1282 ).
I've left the blank 1 pixel gap at every side as directed the below.
Changing the canvas size by using Photoshop:
- Open a splash screen png file in Photoshop
- Click onto the lock icon next to the 'Background' name in the Layers field (to leave blank instead of another color like white) if there is like the below:
- Change the canvas size from Image menu ( Width: 720 pixels to 722 pixels and Height: 1280 pixels to 1282 pixels). Now, should see 1 pixel gap at every side of the splash screen image.
Then you can use C:\Program Files (x86)\Android\android-studio\sdk\tools\draw9patch.bat to convert a 9-patch file. For that open your splash screen on draw9patch app. You should define your logo and expandable areas. Notice the black line the following example splash screen. The black line's thickness is just 1 px ;) Left and Top sides black lines define your splash screen's must display area. Exactly as your designed. Right and Bottom lines define the addable and removable area (automatically repeating areas).
Just do that: Zoom your image's top edge on draw9patch application. Click and drag your mouse to draw line. And press shift + click and drag your mouse to erase line.
If you develop a cross-platform app (like Cordova/PhoneGap) you can find the following address almost all mabile OS splash screen sizes. Click for Windows Phone, WebOS, BlackBerry, Bada-WAC and Bada splash screen sizes.

After more than five years I answer my question. I think that the problem with a negative duration can be solved by a simple correction:
LocalDateTime fromDateTime = LocalDateTime.of(2014, 9, 9, 7, 46, 45);
LocalDateTime toDateTime = LocalDateTime.of(2014, 9, 10, 6, 46, 45);
Period period = Period.between(fromDateTime.toLocalDate(), toDateTime.toLocalDate());
Duration duration = Duration.between(fromDateTime.toLocalTime(), toDateTime.toLocalTime());
if (duration.isNegative()) {
period = period.minusDays(1);
duration = duration.plusDays(1);
}
long seconds = duration.getSeconds();
long hours = seconds / SECONDS_PER_HOUR;
long minutes = ((seconds % SECONDS_PER_HOUR) / SECONDS_PER_MINUTE);
long secs = (seconds % SECONDS_PER_MINUTE);
long time[] = {hours, minutes, secs};
System.out.println(period.getYears() + " years "
+ period.getMonths() + " months "
+ period.getDays() + " days "
+ time[0] + " hours "
+ time[1] + " minutes "
+ time[2] + " seconds.");
Note: The site https://www.epochconverter.com/date-difference now correctly calculates the time difference.
Thank you all for your discussion and suggestions.
The answer shared by @mockinterface is correct. Although I would like to add my 2 cents to it.
If someone is using frameworks like scrapy
the you will have to use /html/body//a[contains(@href,'com')][2]/@href
along with get() like this:
response.xpath('//a[contains(@href,'com')][2]/@href').get()
If you want to safe time and lines of code you can make measuring the function execution time a one line macro:
a) Implement a time measuring class as already suggested above ( here is my implementation for android):
class MeasureExecutionTime{
private:
const std::chrono::steady_clock::time_point begin;
const std::string caller;
public:
MeasureExecutionTime(const std::string& caller):caller(caller),begin(std::chrono::steady_clock::now()){}
~MeasureExecutionTime(){
const auto duration=std::chrono::steady_clock::now()-begin;
LOGD("ExecutionTime")<<"For "<<caller<<" is "<<std::chrono::duration_cast<std::chrono::milliseconds>(duration).count()<<"ms";
}
};
b) Add a convenient macro that uses the current function name as TAG (using a macro here is important, else __FUNCTION__
will evaluate to MeasureExecutionTime
instead of the function you wanto to measure
#ifndef MEASURE_FUNCTION_EXECUTION_TIME
#define MEASURE_FUNCTION_EXECUTION_TIME const MeasureExecutionTime measureExecutionTime(__FUNCTION__);
#endif
c) Write your macro at the begin of the function you want to measure. Example:
void DecodeMJPEGtoANativeWindowBuffer(uvc_frame_t* frame_mjpeg,const ANativeWindow_Buffer& nativeWindowBuffer){
MEASURE_FUNCTION_EXECUTION_TIME
// Do some time-critical stuff
}
Which will result int the following output:
ExecutionTime: For DecodeMJPEGtoANativeWindowBuffer is 54ms
Note that this (as all other suggested solutions) will measure the time between when your function was called and when it returned, not neccesarily the time your CPU was executing the function. However, if you don't give the scheduler any change to suspend your running code by calling sleep() or similar there is no difference between.

import javax.ws.rs.client.Entity;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.MultivaluedHashMap;
import javax.ws.rs.core.MultivaluedMap;
import java.util.Map;
import java.lang.reflect.Type;
import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;
Gson gson = new Gson();
Type type = new TypeToken<Map<String, String>>() {
}.getType();
MultivaluedMap<String, String> formData = new MultivaluedHashMap<String, String>();
formData.add("key1", "value1");
formData.add("key1", "value2");
WebTarget webTarget = ClientBuilder.newClient().target("https://some.server.url/");
String response = webTarget.path("subpath/subpath2").request().post(Entity.form(formData), String.class);
Map<String, String> gsonResponse = gson.fromJson(response, type);
Setting up insets in Interface Builder like shown in the screenshot below
Will result in something like this:
Starting in iOS 6, you can use
-tableView:shouldHighlightRowAtIndexPath:
If you return NO
, it disables both the selection highlighting and the storyboard triggered segues connected to that cell.
The method is called when a touch comes down on a row. Returning NO
to that message halts the selection process and does not cause the currently selected row to lose its selected look while the touch is down.
Beej's famous network programming guide gives a nice explanation:
In some documentation, you'll see mention of a mystical "PF_INET". This is a weird etherial beast that is rarely seen in nature, but I might as well clarify it a bit here. Once a long time ago, it was thought that maybe a address family (what the "AF" in "AF_INET" stands for) might support several protocols that were referenced by their protocol family (what the "PF" in "PF_INET" stands for).
That didn't happen. Oh well. So the correct thing to do is to use AF_INET in your struct sockaddr_in and PF_INET in your call to socket(). But practically speaking, you can use AF_INET everywhere. And, since that's what W. Richard Stevens does in his book, that's what I'll do here.
And, if you don't want to instantiate Class2, declare UpdateEmployee as static and call it like this:
Class2.UpdateEmployee();
However, you'll normally want to do what @parag said.
Simplistic solution:
str := fmt.Sprintf("%s", byteArray)
I'm not sure how performant this is though.
Not sure if there is a publicly accessible/documented way to do this (there are some internal git functions which you can use/abuse in the git source itself)
You could do something like;
if ! git ls-files >& /dev/null; then
echo "not in git"
fi
As stated in PostgreSQL docs here:
The SQL CASE expression is a generic conditional expression, similar to if/else statements in other programming languages.
Code snippet specifically answering your question:
SELECT field1, field2,
CASE
WHEN field1>0 THEN field2/field1
ELSE 0
END
AS field3

According to protocol documentation there are at least three options website designers can use to inform sitemap.xml location to search engines:
So, unless they have chosen to publish the sitemap location on their robots.txt file, you cannot really know where they have put their sitemap.xml files.
If you using bottombar and insted of viewpager you want to set custom fragment replacement logic with retrieve previously save state you can do using below code
String current_frag_tag = null;
String prev_frag_tag = null;
@Override
public void onTabSelected(TabLayout.Tab tab) {
switch (tab.getPosition()) {
case 0:
replaceFragment(new Fragment1(), "Fragment1");
break;
case 1:
replaceFragment(new Fragment2(), "Fragment2");
break;
case 2:
replaceFragment(new Fragment3(), "Fragment3");
break;
case 3:
replaceFragment(new Fragment4(), "Fragment4");
break;
default:
replaceFragment(new Fragment1(), "Fragment1");
break;
}
public void replaceFragment(Fragment fragment, String tag) {
if (current_frag_tag != null) {
prev_frag_tag = current_frag_tag;
}
current_frag_tag = tag;
FragmentManager manager = null;
try {
manager = requireActivity().getSupportFragmentManager();
FragmentTransaction ft = manager.beginTransaction();
if (manager.findFragmentByTag(current_frag_tag) == null) { // No fragment in backStack with same tag..
ft.add(R.id.viewpagerLayout, fragment, current_frag_tag);
if (prev_frag_tag != null) {
try {
ft.hide(Objects.requireNonNull(manager.findFragmentByTag(prev_frag_tag)));
} catch (NullPointerException e) {
e.printStackTrace();
}
}
// ft.show(manager.findFragmentByTag(current_frag_tag));
ft.addToBackStack(current_frag_tag);
ft.commit();
} else {
try {
ft.hide(Objects.requireNonNull(manager.findFragmentByTag(prev_frag_tag)))
.show(Objects.requireNonNull(manager.findFragmentByTag(current_frag_tag))).commit();
} catch (NullPointerException e) {
e.printStackTrace();
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
Inside Child Fragments you can access fragment is visible or not using below method note: you have to implement below method in child fragment
@Override
public void onHiddenChanged(boolean hidden) {
super.onHiddenChanged(hidden);
try {
if(hidden){
adapter.getFragment(mainVideoBinding.viewPagerVideoMain.getCurrentItem()).onPause();
}else{
adapter.getFragment(mainVideoBinding.viewPagerVideoMain.getCurrentItem()).onResume();
}
}catch (Exception e){
}
}
You can make a bookmark with this as the url:
javascript:
var cached_anchors = $$('a');
for (var i in cached_anchors) {
var ca = cached_anchors[i];
if(ca.href.search('sprite') < 0 && ca.href.search('.png') > -1 || ca.href.search('.gif') > -1 || ca.href.search('.jpg') > -1) {
var a = document.createElement('a');
a.href = ca.innerHTML;
a.target = '_blank';
var img = document.createElement('img');
img.src = ca.innerHTML;
img.style.maxHeight = '100px';
a.appendChild(img);
document.getElementsByTagName('body')[0].appendChild(a);
}
}
document.getElementsByTagName('body')[0].removeChild(document.getElementsByTagName('table')[0]);
void(0);
Then just go to chrome://cache and then click your bookmark and it'll show you all the images.
No need to use a macro. Supposing your first string is in A1.
=RIGHT(A1, 4)
Drag this down and you will get your four last characters.
Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()
=RIGHT(TRIMSPACES(A1), 4)
Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:
=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))
I was having the same issue, after i remove the repeat 0 0 part, it solved my problem.
If you're using Jquery to manipulate the DOM, then I have found the following a good way to include logic in a Jquery statement:
$(selector).addClass(A && B?'classIfTrue':'');
Compare NET Objects can help you!
CompareLogic logic = new CompareLogic();
var compare = logic.Compare(obj1, obj2);
comparacao.Differences.ForEach(diff => Debug.Write(diff.PropertyName));
// Or formatted summary
Debug.Write(comparacao.DifferencesString);
Ok, since my attempt to post my solution in a comment failed, here's what I was trying to say. I could do exactly what I wanted from native Python (on Windows, not anywhere else though) with the following code:
import msvcrt
def kbfunc():
x = msvcrt.kbhit()
if x:
ret = ord(msvcrt.getch())
else:
ret = 0
return ret
No need for a 3rd party library. Use the nodejs url module to build a URL with query parameters:
const requestUrl = url.parse(url.format({
protocol: 'https',
hostname: 'yoursite.com',
pathname: '/the/path',
query: {
key: value
}
}));
Then make the request with the formatted url. requestUrl.path
will include the query parameters.
const req = https.get({
hostname: requestUrl.hostname,
path: requestUrl.path,
}, (res) => {
// ...
})
Why is everybody using jQuery for something simple as this.
<body OnLoad="document.myform.mytextfield.focus();">
Just download setuptools-15.2.zip (md5), from here https://pypi.python.org/pypi/setuptools#windows-simplified , and run ez_setup.py.
Most of the answers assume you are looking to do this outside of the database. If your trees are relatively static in nature and you just need to somehow map the trees into the database, you may want to consider using nested set representations on the database side. Check out books by Joe Celko (or here
for an overview by Celko).
If tied to Oracle dbs anyway, check out their CONNECT BY for straight SQL approaches.
With either approach, you could completely skip mapping the trees before you load the data up in the database. Just thought I would offer this up as an alternative, it may be completely inappropriate for your specific needs. The whole "proper order" part of the original question somewhat implies you need the order to be "correct" in the db for some reason? This might push me towards handling the trees there as well.
In this sample, I created a JavaScript progress bar (with percentage display), you can control it and hide it with JavaScript.
In this sample, the progress bar advances every 100ms. You can see it in JSFiddle
var elapsedTime = 0;
var interval = setInterval(function() {
timer()
}, 100);
function progressbar(percent) {
document.getElementById("prgsbarcolor").style.width = percent + '%';
document.getElementById("prgsbartext").innerHTML = percent + '%';
}
function timer() {
if (elapsedTime > 100) {
document.getElementById("prgsbartext").style.color = "#FFF";
document.getElementById("prgsbartext").innerHTML = "Completed.";
if (elapsedTime >= 107) {
clearInterval(interval);
history.go(-1);
}
} else {
progressbar(elapsedTime);
}
elapsedTime++;
}
I used almost the same as @kmccoy, but instead of a keySet()
I did this
hashMap.values().toArray(new MyObject[0]);
It's useful if you want to separate allocation from initialization. STL uses placement new to create container elements.

To install apk manually: copy your apk to to sdk/platform-tools folder and run following command in the same folder
adb install apklocation.apk
You can specify the CFBundleShortVersionString
string in your plist.info and read that programmatically using the provided API.
If you want to scroll the element you're over and prevent the window to scroll, here's a really useful function :
$('.Scrollable').on('DOMMouseScroll mousewheel', function(ev) {
var $this = $(this),
scrollTop = this.scrollTop,
scrollHeight = this.scrollHeight,
height = $this.height(),
delta = (ev.type == 'DOMMouseScroll' ?
ev.originalEvent.detail * -40 :
ev.originalEvent.wheelDelta),
up = delta > 0;
var prevent = function() {
ev.stopPropagation();
ev.preventDefault();
ev.returnValue = false;
return false;
}
if (!up && -delta > scrollHeight - height - scrollTop) {
// Scrolling down, but this will take us past the bottom.
$this.scrollTop(scrollHeight);
return prevent();
} else if (up && delta > scrollTop) {
// Scrolling up, but this will take us past the top.
$this.scrollTop(0);
return prevent();
}
});
Apply the class "Scrollable" to your element and that's it!
<mat-form-field>
<mat-select placeholder="Vacancies" [(ngModel)]="vacanciesSpinnerSelectedItem.code" (ngModelChange)="spinnerClick1($event)"
[ngModelOptions]="{standalone: true}" required>
<mat-option *ngFor="let spinnerValue of vacanciesSpinnerValues" [value]="spinnerValue?.code">{{spinnerValue.description}}</mat-option>

I used this for angular Material dropdown. works fine
The 2nd parameter of http.post is the body of the message, ie the payload and not the url search parameters. Pass data
in that parameter.
From the documentation
post(url: string, body: any, options?: RequestOptionsArgs) : Observable<Response>
public post(cmd: string, data: object): Observable<any> {
const params = new URLSearchParams();
params.set('cmd', cmd);
const options = new RequestOptions({
headers: this.getAuthorizedHeaders(),
responseType: ResponseContentType.Json,
params: params,
withCredentials: false
});
console.log('Options: ' + JSON.stringify(options));
return this.http.post(this.BASE_URL, data, options)
.map(this.handleData)
.catch(this.handleError);
}
You should also check out the 1st parameter (BASE_URL
). It must contain the complete url (minus query string) that you want to reach. I mention in due to the name you gave it and I can only guess what the value currently is (maybe just the domain?).
Also there is no need to call JSON.stringify
on the data/payload that is sent in the http body.
If you still can't reach your end point look in the browser's network activity in the development console to see what is being sent. You can then further determine if the correct end point is being called wit the correct header and body. If it appears that is correct then use POSTMAN or Fiddler or something similar to see if you can hit your endpoint that way (outside of Angular).
Simple solution for scrolling specific element down
const element = document.getElementById("element-with-scroll");
element.scrollTop = element.scrollHeight - 10;

android:id="@+id/my_awesome_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"

Also, you are giving it the same "ID" twice, please remove the "id" from your include:
<include android:id="@+id/toolbar" layout="@layout/toolbar" />
You can use tuples like this: SELECT * FROM table WHERE (Col, 1) IN ((123,1),(123,1),(222,1),....)
There are no restrictions on number of these. It compares pairs.
It seems in the 2 years since this was asked, the other browsers have caught up (at least on Windows... not sure about others). You can set a "title" attribute on the option tag:
<option value="" title="Tooltip">Some option</option>

Just remove 'pdf' if you want files of any type.
Some answers are partially wrong, and some facts in them are partially wrong as well.
Answer your question: Yes! You can.
In Typescript
class A {
private a1;
private a2;
}
Generates the following code in Javascript:
var A = /** @class */ (function () {
function A() {
}
return A;
}());
as @Erik_Cupal said, you could just do:
let a = new A();
let array = return Object.getOwnPropertyNames(a);
But this is incomplete. What happens if your class has a custom constructor? You need to do a trick with Typescript because it will not compile. You need to assign as any:
let className:any = A;
let a = new className();// the members will have value undefined
A general solution will be:
class A {
private a1;
private a2;
constructor(a1:number, a2:string){
this.a1 = a1;
this.a2 = a2;
}
}
class Describer{
describeClass( typeOfClass:any){
let a = new typeOfClass();
let array = Object.getOwnPropertyNames(a);
return array;//you can apply any filter here
}
}
For better understanding this will reference depending on the context.
Here is solution for legacy datatable 1.9.4

});
$('#table').dataTable().fnClearTable();
$('#table').dataTable().fnAddData(myData2);
This is also an alternate use of case-when...

Here is my simple solution:
1 - Define your fragment
public class MyFragment extends Fragment {
private String parameter;
public MyFragment() {
}
public void setParameter(String parameter) {
this.parameter = parameter;
}
}
2 - Create your new fragment and populate the parameter
myfragment = new MyFragment();
myfragment.setParameter("here the value of my parameter");
3 - Enjoy it!
Obviously you can change the type and the number of parameters. Quick and easy.
coalesce
is supported in both Oracle and SQL Server and serves essentially the same function as nvl
and isnull
. (There are some important differences, coalesce
can take an arbitrary number of arguments, and returns the first non-null one. The return type for isnull
matches the type of the first argument, that is not true for coalesce
, at least on SQL Server.)
It seems that linux will say "command not found" even if you explicitly give the path to the file.
[veeam@jsandbox ~]$ sudo /tmp/uid.sh;echo $?
sudo: /tmp/uid.sh: command not found
1
[veeam@jsandbox ~]$ chmod +x /tmp/uid.sh
[veeam@jsandbox ~]$ sudo /tmp/uid.sh;echo $?
0
It's a somewhat misleading error, however it's probably technically correct. A file is not a command until its executable, and so cannot be found.
The rule for the caret is:
A caret at the line end, appends the next line, the first character of the appended line will be escaped.
You can use the caret multiple times, but the complete line must not exceed the maximum line length of ~8192 characters (Windows XP, Windows Vista, and Windows 7).
echo Test1
echo one ^
two ^
three ^
four^
*
--- Output ---
Test1
one two three four*
echo Test2
echo one & echo two
--- Output ---
Test2
one
two
echo Test3
echo one & ^
echo two
--- Output ---
Test3
one
two
echo Test4
echo one ^
& echo two
--- Output ---
Test4
one & echo two
To suppress the escaping of the next character you can use a redirection.
The redirection has to be just before the caret. But there exist one curiosity with redirection before the caret.
If you place a token at the caret the token is removed.
echo Test5
echo one <nul ^
& echo two
--- Output ---
Test5
one
two
echo Test6
echo one <nul ThisTokenIsLost^
& echo two
--- Output ---
Test6
one
two
And it is also possible to embed line feeds into the string:
setlocal EnableDelayedExpansion
set text=This creates ^
a line feed
echo Test7: %text%
echo Test8: !text!
--- Output ---
Test7: This creates
Test8: This creates
a line feed
The empty line is important for the success. This works only with delayed expansion, else the rest of the line is ignored after the line feed.
It works, because the caret at the line end ignores the next line feed and escapes the next character, even if the next character is also a line feed (carriage returns are always ignored in this phase).
Hooking .remove()
is not the best way to handle this as there are many ways to remove elements from the page (e.g. by using .html()
, .replace()
, etc).
In order to prevent various memory leak hazards, internally jQuery will try to call the function jQuery.cleanData()
for each removed element regardless of the method used to remove it.
See this answer for more details: javascript memory leaks
So, for best results, you should hook the cleanData
function, which is exactly what the jquery.event.destroyed plugin does:
http://v3.javascriptmvc.com/jquery/dist/jquery.event.destroyed.js
For me, it was all about setting up my web server to use the latest-and-greatest tech to support my ASP.NET 5 application!
The following URL gave me all the tips I needed:

Hope this helps :)
You don't need to escape it inside. You can use the |
character to delimit searches.
"\"foo\"\'bar\'".replace(/("|')/g, "")
The basic problem while migrating from MySQL I faced was, I thought of the term database
to be same in PostgreSQL also, but it is not. So if we are going to switch the database from our application or pgAdmin
, the result would not be as expected.
As in my case, we have separate schemas (Considering PostgreSQL terminology here.) for each customer and separate admin schema. So in application, I have to switch between schemas.
For this, we can use the SET search_path
command. This does switch the current schema to the specified schema name for the current session.
example:
SET search_path = different_schema_name;
This changes the current_schema to the specified schema for the session. To change it permanently, we have to make changes in postgresql.conf
file.
A very simple and elegant solution to this is provided by W3C. Simply use the margin:0 auto declaration as follows:
.top_image img { margin:0 auto; }
More information and examples from W3C.
This is not the exact answer, but this might be helpful for the people looking to solve some problem with the approach of ordering row before group by in mysql.
I came to this thread, when I wanted to find the latest row(which is order by date desc
but get the only one result for a particular column type, which is group by column name
).
One other approach to solve such problem is to make use of aggregation.
So, we can let the query run as usual, which sorted asc and introduce new field as max(doc) as latest_doc
, which will give the latest date, with grouped by the same column.
Suppose, you want to find the data of a particular column now and max aggregation cannot be done.
In general, to finding the data of a particular column, you can make use of GROUP_CONCAT aggregator
, with some unique separator which can't be present in that column, like GROUP_CONCAT(string SEPARATOR ' ') as new_column
, and while you're accessing it, you can split/explode the new_column field.
Again, this might not sound to everyone. I did it, and liked it as well because I had written few functions and I couldn't run subqueries. I am working on codeigniter framework for php.
Not sure of the complexity as well, may be someone can put some light on that.
Regards :)
Hi I have been using this page a lot for constraints and "how to". It took me forever to get to the point of realizing I needed:
myView.translatesAutoresizingMaskIntoConstraints = NO;
to get this example to work. Thank you Userxxx, Rob M. and especially larsacus for the explanation and code here, it has been invaluable.
Here is the code in full to get the examples above to run:
UIView *myView = [[UIView alloc] init];
myView.backgroundColor = [UIColor redColor];
myView.translatesAutoresizingMaskIntoConstraints = NO; //This part hung me up
[self.view addSubview:myView];
//needed to make smaller for iPhone 4 dev here, so >=200 instead of 748
[self.view addConstraints:[NSLayoutConstraint
constraintsWithVisualFormat:@"V:|-[myView(>=200)]-|"
options:NSLayoutFormatDirectionLeadingToTrailing
metrics:nil
views:NSDictionaryOfVariableBindings(myView)]];
[self.view addConstraints:[NSLayoutConstraint
constraintsWithVisualFormat:@"H:[myView(==200)]-|"
options:NSLayoutFormatDirectionLeadingToTrailing
metrics:nil
views:NSDictionaryOfVariableBindings(myView)]];
You can increase client_max_body_size and upload_max_filesize + post_max_size all day long. Without adjusting HTTP timeout it will never work.
//You need to adjust this, and probably on PHP side also. client_body_timeout 2min // 1GB fileupload
You could use the rails_default_value gem. eg:
class Foo < ActiveRecord::Base
# ...
default :bar => 'some default value'
# ...
end
Windows solution: Replace spawn
with node-cross-spawn. For instance like this at the beginning of your app.js:
(function() {
var childProcess = require("child_process");
childProcess.spawn = require('cross-spawn');
})();
alert( "Size: " + $("li").size() );
or
alert( "Size: " + $("li").length );
You can find some examples of the .size() method here.

Sometime in the future. Applicable to Windows 8.1 machine. Run the following commands
npm install -g @angular/cli
Log out or restart your machine.
This should add the required env path, rather than doing it manually.
Here is what you can do if you want to add a column of numbers in Excel. ( I am using Excel 2010 but should not make a difference.)
Example: Lets say you want to add the cells in Column B form B10 to B100 & want the answer to be in cell X or be Variable X ( X can be any cell or any variable you create such as Dim X as integer, etc). Here is the code:
Range("B5") = "=SUM(B10:B100)"
or
X = "=SUM(B10:B100)
There are no quotation marks inside the parentheses in "=Sum(B10:B100) but there are quotation marks inside the parentheses in Range("B5"). Also there is a space between the equals sign and the quotation to the right of it.
It will not matter if some cells are empty, it will simply see them as containing zeros!
This should do it for you!

, it is option of Babel compiler
that commands to not include superfluous whitespace characters and line terminators. some times ago its threshold was 100KB
but now is 500KB

Ok so the answer I got helped me in the right direction and I am very thankful. It helped me figure out how to actually record on the iPhone, but I thought I would also include some helpful code I got from the iPhone Reference Library:
I used this code and added it to the avTouch example fairly easily. With the above code sample and the sample from the reference library, I was able to get this to work pretty good.
After 7 years... the facelets solution still works fine for me as a jsf user
include the namespace as
xmlns:fn="http://java.sun.com/jsp/jstl/functions"
and use the EL as
#{fn:length(myBean.someList)}
for example if using in jsf ui:fragment below example works fine
<ui:fragment rendered="#{fn:length(myBean.someList) gt 0}">
<!-- Do something here-->
</ui:fragment>
Have a look at the content by type web part - http://codeplex.com/eoffice - probably the most flexible viewing web part.
1) The function returns a cell for a table view yes? So, the returned object is of type UITableViewCell
. These are the objects that you see in the table's rows. This function basically returns a cell, for a table view.
But you might ask, how the function would know what cell to return for what row, which is answered in the 2nd question
2)NSIndexPath
is essentially two things-
Because your table might be divided to many sections and each with its own rows, this NSIndexPath
will help you identify precisely which section and which row. They are both integers. If you're a beginner, I would say try with just one section.
It is called if you implement the UITableViewDataSource
protocol in your view controller. A simpler way would be to add a UITableViewController
class. I strongly recommend this because it Apple has some code written for you to easily implement the functions that can describe a table. Anyway, if you choose to implement this protocol yourself, you need to create a UITableViewCell
object and return it for whatever row. Have a look at its class reference to understand re-usablity because the cells that are displayed in the table view are reused again and again(this is a very efficient design btw).
As for when you have two table views, look at the method. The table view is passed to it, so you should not have a problem with respect to that.

'It' requires a dll file called cvextern.dll . 'It' can be either your own cs file or some other third party dll which you are using in your project.
To call native dlls to your own cs file, copy the dll into your project's root\lib directory and add it as an existing item. (Add -Existing item) and use Dllimport with correct location.
For third party , copy the native library to the folder where the third party library resides and add it as an existing item.
After building make sure that the required dlls are appearing in Build folder. In some cases it may not appear or get replaced in Build folder. Delete the Build folder manually and build again.

Add NestedScrollView around layout which you want to scroll, this will perfectly work
You can also use "shouldReceiveTouch" method of UIGestureRecognizer
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch: (UITouch *)touch {
UIView *view = touch.view;
NSLog(@"%d", view.tag);
}
Dont forget to set delegate of your gesture recognizer.
If you have Guava on your classpath, the following is a pretty readable alternative. Guava even has a fairly sensible custom List implementation for this case, so this shouldn't be inefficient.
for(char c : Lists.charactersOf(yourString)) {
// Do whatever you want
}
UPDATE: As @Alex noted, with Java 8 there's also CharSequence#chars
to use. Even the type is IntStream, so it can be mapped to chars like:
yourString.chars()
.mapToObj(c -> Character.valueOf((char) c))
.forEach(c -> System.out.println(c)); // Or whatever you want

If I recall correctly Twig doesn't support ||
and &&
operators, but requires or
and and
to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.
{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}
Expressions
Expressions can be used in {% blocks %} and ${ expressions }.
Operator Description
== Does the left expression equal the right expression?
+ Convert both arguments into a number and add them.
- Convert both arguments into a number and substract them.
* Convert both arguments into a number and multiply them.
/ Convert both arguments into a number and divide them.
% Convert both arguments into a number and calculate the rest of the integer division.
~ Convert both arguments into a string and concatenate them.
or True if the left or the right expression is true.
and True if the left and the right expression is true.
not Negate the expression.
For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:
{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

Not necessarily the best practice, but my environment was a local network with several machines which needed access to the selenium.
When running the chromedriver, you can pass through a param like so :
chromedriver --whitelisted-ips=""
This will basically whitelist all IP's, not always an ideal solution of course and be careful with it for production enviornments, but you should be presented with a verbose warning :
Starting ChromeDriver 2.16.333244 (15fb740a49ab3660b8f8d496cfab2e4d37c7e6ca) on port 9515 All remote connections are allowed. Use a whitelist instead!
A work-around at best, but it works.
What is your PHP version? Extension "Mysql" was deprecated in PHP 5.5.0. Use extension Mysqli (like mysqli_query).

end
Works like a charm!
ssh -t 'command; bash -l'
will execute the command and then start up a login shell when it completes. For example:

A callback
is a function passed as an parameter to a Higher Order Function
(wikipedia). A simple implementation of a callback would be:
const func = callback => callback('Hello World!');
To call the function, simple pass another function as argument to the function defined.
func(string => console.log(string));
Use CHAR
:
=Char(34)&"This is in quotes"&Char(34)
Should evaluate to:
"This is in quotes"
Functions that send/modify HTTP headers must be invoked before any output is made. summary ? Otherwise the call fails:
Warning: Cannot modify header information - headers already sent (output started at script:line)
Some functions modifying the HTTP header are:
Output can be:
Unintentional:
<?php
or after ?>
Intentional:
print
, echo
and other functions producing output<html>
sections prior <?php
code. To understand why headers must be sent before output it's necessary to look at a typical HTTP response. PHP scripts mainly generate HTML content, but also pass a set of HTTP/CGI headers to the webserver:
HTTP/1.1 200 OK
Powered-By: PHP/5.3.7
Vary: Accept-Encoding
Content-Type: text/html; charset=utf-8
<html><head><title>PHP page output page</title></head>
<body><h1>Content</h1> <p>Some more output follows...</p>
and <a href="/"> <img src=internal-icon-delayed> </a>
The page/output always follows the headers. PHP has to pass the headers to the webserver first. It can only do that once. After the double linebreak it can nevermore amend them.
When PHP receives the first output (print
, echo
, <html>
) it will
flush all collected headers. Afterwards it can send all the output
it wants. But sending further HTTP headers is impossible then.
The header()
warning contains all relevant information to
locate the problem cause:
Warning: Cannot modify header information - headers already sent by (output started at /www/usr2345/htdocs/auth.php:52) in /www/usr2345/htdocs/index.php on line 100
Here "line 100" refers to the script where the header()
invocation failed.
The "output started at" note within the parenthesis is more significant.
It denominates the source of previous output. In this example it's auth.php
and line 52
. That's where you had to look for premature output.
Typical causes:
Intentional output from print
and echo
statements will terminate
the opportunity to send HTTP headers. The application flow must
be restructured to avoid that. Use functions
and templating schemes. Ensure header()
calls occur before messages
are written out.
Functions that produce output include
print
, echo
, printf
, vprintf
trigger_error
, ob_flush
, ob_end_flush
, var_dump
, print_r
readfile
, passthru
, flush
, imagepng
, imagejpeg
among others and user-defined functions.
Unparsed HTML sections in a .php
file are direct output as well.
Script conditions that will trigger a header()
call must be noted
before any raw <html>
blocks.
<!DOCTYPE html>
<?php
// Too late for headers already.
Use a templating scheme to separate processing from output logic.
<?php
for "script.php line 1" warningsIf the warning refers to output in line 1
, then it's mostly
leading whitespace, text or HTML before the opening <?php
token.
<?php
# There's a SINGLE space/newline before <? - Which already seals it.
Similarly it can occur for appended scripts or script sections:
?>
<?php
PHP actually eats up a single linebreak after close tags. But it won't compensate multiple newlines or tabs or spaces shifted into such gaps.
Linebreaks and spaces alone can be a problem. But there are also "invisible"
character sequences which can cause this. Most famously the
UTF-8 BOM (Byte-Order-Mark)
which isn't displayed by most text editors. It's the byte sequence EF BB BF
, which
is optional and redundant for UTF-8 encoded documents. PHP however has to treat
it as raw output. It may show up as the characters 
in the output (if the client
interprets the document as Latin-1) or similar "garbage".
In particular graphical editors and Java based IDEs are oblivious to its presence. They don't visualize it (obliged by the Unicode standard). Most programmer and console editors however do:
There it's easy to recognize the problem early on. Other editors may identify
its presence in a file/settings menu (Notepad++ on Windows can identify and
remedy the problem),
Another option to inspect the BOMs presence is resorting to an hexeditor.
On *nix systems hexdump
is usually available,
if not a graphical variant which simplifies auditing these and other issues:
An easy fix is to set the text editor to save files as "UTF-8 (no BOM)" or similar such nomenclature. Often newcomers otherwise resort to creating new files and just copy&pasting the previous code back in.
There are also automated tools to examine and rewrite text files
(sed
/awk
or recode
).
For PHP specifically there's the phptags
tag tidier.
It rewrites close and open tags into long and short forms, but also easily
fixes leading and trailing whitespace, Unicode and UTF-x BOM issues:
phptags --whitespace *.php
It's sane to use on a whole include or project directory.
?>
If the error source is mentioned as behind the
closing ?>
then this is where some whitespace or raw text got written out.
The PHP end marker does not terminate script executation at this
point. Any text/space characters after it will be written out as page content
still.
It's commonly advised, in particular to newcomers, that trailing ?>
PHP
close tags should be omitted. This eschews a small portion of these cases.
(Quite commonly include()d
scripts are the culprit.)
It's typically a PHP extension or php.ini setting if no error source is concretized.
gzip
stream encoding setting
or the ob_gzhandler
.extension=
module
generating an implicit PHP startup/warning message.If another PHP statement or expression causes a warning message or notice being printeded out, that also counts as premature output.
In this case you need to eschew the error,
delay the statement execution, or suppress the message with e.g.
isset()
or @()
-
when either doesn't obstruct debugging later on.
If you have error_reporting
or display_errors
disabled per php.ini
,
then no warning will show up. But ignoring errors won't make the problem go
away. Headers still can't be sent after premature output.
So when header("Location: ...")
redirects silently fail it's very
advisable to probe for warnings. Reenable them with two simple commands
atop the invocation script:
error_reporting(E_ALL);
ini_set("display_errors", 1);
Or set_error_handler("var_dump");
if all else fails.
Speaking of redirect headers, you should often use an idiom like this for final code paths:
exit(header("Location: /finished.html"));
Preferrably even a utility function, which prints a user message
in case of header()
failures.
PHPs output buffering is a workaround to alleviate this issue. It often works reliably, but shouldn't substitute for proper application structuring and separating output from control logic. Its actual purpose is minimizing chunked transfers to the webserver.
The output_buffering=
setting nevertheless can help.
Configure it in the php.ini
or via .htaccess
or even .user.ini on
modern FPM/FastCGI setups.
Enabling it will allow PHP to buffer output instead of passing it to the webserver
instantly. PHP thus can aggregate HTTP headers.
It can likewise be engaged with a call to ob_start();
atop the invocation script. Which however is less reliable for multiple reasons:
Even if <?php ob_start(); ?>
starts the first script, whitespace or a
BOM might get shuffled before, rendering it ineffective.
It can conceal whitespace for HTML output. But as soon as the application
logic attempts to send binary content (a generated image for example),
the buffered extraneous output becomes a problem. (Necessitating ob_clean()
as furher workaround.)
The buffer is limited in size, and can easily overrun when left to defaults. And that's not a rare occurence either, difficult to track down when it happens.
Both approaches therefore may become unreliable - in particular when switching between development setups and/or production servers. Which is why output buffering is widely considered just a crutch / strictly a workaround.
See also the basic usage example in the manual, and for more pros and cons:
If you didn't get the headers warning before, then the output buffering php.ini setting has changed. It's likely unconfigured on the current/new server.
headers_sent()
You can always use headers_sent()
to probe if
it's still possible to... send headers. Which is useful to conditionally print
an info or apply other fallback logic.
if (headers_sent()) {
die("Redirect failed. Please click on this link: <a href=...>");
}
else{
exit(header("Location: /user.php"));
}
Useful fallback workarounds are:
<meta>
tagIf your application is structurally hard to fix, then an easy (but
somewhat unprofessional) way to allow redirects is injecting a HTML
<meta>
tag. A redirect can be achieved with:
<meta http-equiv="Location" content="http://example.com/">
Or with a short delay:
<meta http-equiv="Refresh" content="2; url=../target.html">
This leads to non-valid HTML when utilized past the <head>
section.
Most browsers still accept it.
As alternative a JavaScript redirect can be used for page redirects:
<script> location.replace("target.html"); </script>
While this is often more HTML compliant than the <meta>
workaround,
it incurs a reliance on JavaScript-capable clients.
Both approaches however make acceptable fallbacks when genuine HTTP header() calls fail. Ideally you'd always combine this with a user-friendly message and clickable link as last resort. (Which for instance is what the http_redirect() PECL extension does.)
setcookie()
and session_start()
are also affectedBoth setcookie()
and session_start()
need to send a Set-Cookie:
HTTP header.
The same conditions therefore apply, and similar error messages will be generated
for premature output situations.
(Of course they're furthermore affected by disabled cookies in the browser, or even proxy issues. The session functionality obviously also depends on free disk space and other php.ini settings, etc.)

In addition to the string operations (MOVS/INS/STOS/CMPS/SCASB/W/D/Q etc.) mentioned in the other answers, I wanted to add that there are also more "modern" x86 assembly instructions that implicitly use at least EDI/RDI:
The SSE2 MASKMOVDQU
(and the upcoming AVX VMASKMOVDQU
) instruction selectively write bytes from an XMM register to memory pointed to by EDI/RDI.
There are long-term maintenance risks as well. First, I'd recommend reading about how Lombok actually works, e.g. some answers from its developers here.
The official site also contains a list of downsides, including this quote from Reinier Zwitserloot:
It's a total hack. Using non-public API. Presumptuous casting (knowing that an annotation processor running in javac will get an instance of JavacAnnotationProcessor, which is the internal implementation of AnnotationProcessor (an interface), which so happens to have a couple of extra methods that are used to get at the live AST).
On eclipse, it's arguably worse (and yet more robust) - a java agent is used to inject code into the eclipse grammar and parser class, which is of course entirely non-public API and totally off limits.
If you could do what lombok does with standard API, I would have done it that way, but you can't. Still, for what its worth, I developed the eclipse plugin for eclipse v3.5 running on java 1.6, and without making any changes it worked on eclipse v3.4 running on java 1.5 as well, so it's not completely fragile.
As a summary, while Lombok may save you some development time, if there is a non-backwards compatible javac update (e.g. a vulnerability mitigation) Lombok might get you stuck with an old version of Java while the developers scramble to update their usage of those internal APIs. Whether this is a serious risk obviously depends on the project.
Not sure why SSMS doesn’t take into account execution order but it just doesn’t. This is not an issue for small databases but what if your database has 200 objects? In that case order of execution does matter because it’s not really easy to go through all of these.
For unordered scripts generated by SSMS you can go following
a) Execute script (some objects will be inserted some wont, there will be some errors)
b) Remove all objects from the script that have been added to database
c) Go back to a) until everything is eventually executed
Alternative option is to use third party tool such as ApexSQL Script or any other tools already mentioned in this thread (SSMS toolpack, Red Gate and others).
All of these will take care of the dependencies for you and save you even more time.

Since Ruby 2.4 there is a built in full Unicode case mapping. Source: https://stackoverflow.com/a/38016153/888294. See Ruby 2.4.0 documentation for details: https://ruby-doc.org/core-2.4.0/String.html#method-i-downcase
Here's my attempt. To disable a tab:
Code:
var toggleTabs = function(state) {
disabledTabs = ['#tab2', '#tab3'];
$.each(disabledTabs, $.proxy(function(idx, tabSelector) {
tab = $(tabSelector);
if (tab.length) {
if (state) {
// Enable tab click.
$(tab).toggleClass('disabled', false);
$('a', tab).attr('data-toggle', 'tab').off('click');
} else {
// Disable tab click.
$(tab).toggleClass('disabled', true);
$('a', tab).removeAttr('data-toggle').on('click', function(e){
e.preventDefault();
});
}
}
}, this));
};
toggleTabs.call(myTabContainer, true);
Insert this in your Makefile
$(MAKE) -C $(KDIR) M=$(PWD) modules_install
it will install the module in the directory /lib/modules/<var>/extra/
After make , insert module with modprobe module_name (without .ko extension)
OR
After your normal make, you copy module module_name.ko into directory /lib/modules/<var>/extra/
then do modprobe module_name (without .ko extension)
For me, this solution worked like a charm: http://home.pacific.net.hk/~edx/bin/readmeocx.txt
Fix these two lines like that:
Object={F9043C88-F6F2-101A-A3C9-08002B2F49FB}#1.2#0; COMDLG32.OCX
Object={831FDD16-0C5C-11D2-A9FC-0000F8754DA1}#2.0#0; MSCOMCTL.OCX
Search the files (.vbp and .frm) for lines like this:
Begin ComctlLib.ImageList ILTree
Begin ComctlLib.StatusBar StatusBar1
Begin ComctlLib.Toolbar Toolbar1`
The lines may be like this:
Begin MSComctlLib.ImageList ILTree
Begin MSComctlLib.StatusBar StatusBar1
Begin MSComctlLib.Toolbar Toolbar1`
Here is a really easy way of doing it:https://github.com/JagCesar/iOS-blur
Just copy the layer of UIToolbar and you're done, AMBlurView does it for you. Okay, it's not as blurry as control center, but is's blurry enough.
Remember that iOS7 is under NDA.
If you completely want to clear the session you can use this:
session_unset();
session_destroy();
Actually both are not neccessary but it does not hurt.
If you want to clear only a specific part I think you need this:
unset($_SESSION['Products']);
//or
$_SESSION['Products'] = "";
depending on what you need.
This is really old, but I wanted to add my slight variation for anyone else who may stumble across this. Regular expressions are powerful things.
To keep the text which falls between the equal sign and the comma:
-replace "^.*?=(.*?),.*?$",'$1'
This regular expression starts at the beginning of the line, wipes all characters until the first equal sign, captures every character until the next comma, then wipes every character until the end of the line. It then replaces the entire line with the capture group (anything within the parentheses). It will match any line that contains at least one equal sign followed by at least one comma. It is similar to the suggestion by Trix, but unlike that suggestion, this will not match lines which only contain either an equal sign or a comma, it must have both in order.
In my xampp control panel, Click config to open php.ini
remove ; in
;extension=php_intl.dll
Then restart the apache.
$('[data-dismiss=modal]').on('click', function (e)
{
var $t = $(this),
target = $t[0].href || $t.data("target") || $t.parents('#myModal') || [];
$(target)
.find("input")
.val('')
.end()
.find("input[type=checkbox]")
.prop("checked", " ")
.end();
$("span.inerror").html(' ');
$("span.inerror").removeClass("inerror");
document.getElementById("errorDiv1").innerHTML=" ";
})
This code can be used on close(data-dismiss)of modal.(to clear all fields)
Here I have cleared my input fields and my div as id="errorDiv1"
which holds all validation errors.
With this code I can also clear other validation errors having class as inerror
which is specified in span tag with class inerror
and which was not possible using document.getElementsByClassName
Simplest way is to add this JAVA library using Gradle:
compile 'se.simbio.encryption:library:2.0.0'
You can use it as simple as this:
Encryption encryption = Encryption.getDefault("Key", "Salt", new byte[16]);
String encrypted = encryption.encryptOrNull("top secret string");
String decrypted = encryption.decryptOrNull(encrypted);
My fix was to remove the double quotes that I had enclosed the JAVA_HOME path in.
Instead of declaring JAVA_HOME as "C\Program Files..."
I removed the " and declared JAVA_HOME as C\Program Files...
I am on Win 7, x64
A slightly more concise example that builds on top of the other answers here. I leveraged the code generation that is shipped with Visual Studio to remove most of the extra invocation code and replaced it with typed objects instead.

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct
approach is executed like:
business_key
values to a temporary tableThe group by
could be executed like:
business key
in a hashtableThe first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.
Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.
you can always use new stdClass()
. Example code:
$object = new stdClass();
$object->property = 'Here we go';
var_dump($object);
/*
outputs:
object(stdClass)#2 (1) {
["property"]=>
string(10) "Here we go"
}
*/
Also as of PHP 5.4 you can get same output with:
$object = (object) ['property' => 'Here we go'];
What solution you need depends on whether you want your array to retain its order, or not.
Generally, you never only have the array pointer, you also have a variable holding its current logical size, as well as a variable holding its allocated size. I'm also assuming that the removeIndex
is within the bounds of the array. With that given, the removal is simple:
array[removeIndex] = array[--logicalSize];
That's it. You simply copy the last array element over the element that is to be removed, decrementing the logicalSize
of the array in the process.
If removeIndex == logicalSize-1
, i.e. the last element is to be removed, this degrades into a self-assignment of that last element, but that is not a problem.
memmove(array + removeIndex, array + removeIndex + 1, (--logicalSize - removeIndex)*sizeof(*array));
A bit more complex, because now we need to call memmove()
to perform the shifting of elements, but still a one-liner. Again, this also updates the logicalSize
of the array in the process.
Execute in bash:
redis-cli KEYS "prefix:*" | xargs redis-cli DEL
UPDATE
Ok, i understood. What about this way: store current additional incremental prefix and add it to all your keys. For example:
You have values like this:
prefix_prefix_actuall = 2
prefix:2:1 = 4
prefix:2:2 = 10
When you need to purge data, you change prefix_actuall first (for example set prefix_prefix_actuall = 3), so your application will write new data to keys prefix:3:1 and prefix:3:2. Then you can safely take old values from prefix:2:1 and prefix:2:2 and purge old keys.
The accepted answer here does not work for my use case. I needed to be able to dynamically create parameters in one job and pass them into another. As Mark McKenna mentions there is seemingly no way to export a variable from a shell build step to the post build actions.
I achieved a workaround using the Parameterized Trigger Plugin by writing the values to a file and using that file as the parameters to import via 'Add post-build action' -> 'Trigger parameterized build...' then selecting 'Add Parameters' -> 'Parameters from properties file'.
Colon does not have special meaning in a character class and does not need to be escaped. According to the PHP regex docs, the only characters that need to be escaped in a character class are the following:
All non-alphanumeric characters other than
\
,-
,^
(at the start) and the terminating]
are non-special in character classes, but it does no harm if they are escaped.
For more info about Java regular expressions, see the docs.
If you are using the less version to compile Bootstrap modify @modal-backdrop-opacity in your variables override file $modal-backdrop-opacity for scss.
I've run into this as well, solution is usually to be sure to run the program as an administrator (right click, run as administrator.)
It have happened because you are trying to use the property "OffenceBox.Text" like a method. Try to remove parenteses from OffenceBox.Text()
and it'll work fine.
Remember that you cannot create a method and a property with the same name in a class.
By the way, some alias could confuse you, since sometimes it's method or property, e.g: "Count" alias:
Namespace: System.Linq
using System.Linq
namespace Teste
{
public class TestLinq
{
public return Foo()
{
var listX = new List<int>();
return listX.Count(x => x.Id == 1);
}
}
}
Namespace: System.Collections.Generic
using System.Collections.Generic
namespace Teste
{
public class TestList
{
public int Foo()
{
var listX = new List<int>();
return listX.Count;
}
}
}
In your activity, where you defined your listview
you write
listview.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?>adapter,View v, int position){
ItemClicked item = adapter.getItemAtPosition(position);
Intent intent = new Intent(Activity.this,destinationActivity.class);
//based on item add info to intent
startActivity(intent);
}
});
in your adapter's getItem you write
public ItemClicked getItem(int position){
return items.get(position);
}
FileReader API with jQuery, simple example.
( function ( $ ) {_x000D_
// Add click event handler to button_x000D_
$( '#load-file' ).click( function () {_x000D_
if ( ! window.FileReader ) {_x000D_
return alert( 'FileReader API is not supported by your browser.' );_x000D_
}_x000D_
var $i = $( '#file' ), // Put file input ID here_x000D_
input = $i[0]; // Getting the element from jQuery_x000D_
if ( input.files && input.files[0] ) {_x000D_
file = input.files[0]; // The file_x000D_
fr = new FileReader(); // FileReader instance_x000D_
fr.onload = function () {_x000D_
// Do stuff on onload, use fr.result for contents of file_x000D_
$( '#file-content' ).append( $( '<div/>' ).html( fr.result ) )_x000D_
};_x000D_
//fr.readAsText( file );_x000D_
fr.readAsDataURL( file );_x000D_
} else {_x000D_
// Handle errors here_x000D_
alert( "File not selected or browser incompatible." )_x000D_
}_x000D_

To read as text... uncomment //fr.readAsText(file);
line and comment fr.readAsDataURL(file);
To do this you want to loop through each row of your query results and use this info for each of your drop down's options. You should be able to adjust the code below fairly easily to meet your needs.
// Assume $db is a PDO object
$query = $db->query("YOUR QUERY HERE"); // Run your query
echo '<select name="DROP DOWN NAME">'; // Open your drop down box
// Loop through the query results, outputing the options one by one
while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
echo '<option value="'.$row['something'].'">'.$row['something'].'</option>';
}
echo '</select>';// Close your drop down box
Once, this happens to me as well. and when I googled the matter, I got to know that this happens when the permissions on the file is wrongfully set to 000 (which means that no one can read, write, or execute that file). Then I just changed my file permission privilege into Read & Write and it's worked for me.
To change file permission settings on mac: Right click on the particular file and click on Get info from dropdown menu and refer to the sharing and permissions panel and change privilege settings into Read & Write

If you're familiar with Python argparse, and don't mind calling python to parse bash arguments, there is a piece of code I found really helpful and super easy to use called argparse-bash https://github.com/nhoffman/argparse-bash
Example take from their example.sh script:
#!/bin/bash
source $(dirname $0)/argparse.bash || exit 1
argparse "$@" <<EOF || exit 1
parser.add_argument('infile')
parser.add_argument('outfile')
parser.add_argument('-a', '--the-answer', default=42, type=int,
help='Pick a number [default %(default)s]')
parser.add_argument('-d', '--do-the-thing', action='store_true',
default=False, help='store a boolean [default %(default)s]')
parser.add_argument('-m', '--multiple', nargs='+',
help='multiple values allowed')
EOF
echo required infile: "$INFILE"
echo required outfile: "$OUTFILE"
echo the answer: "$THE_ANSWER"
echo -n do the thing?
if [[ $DO_THE_THING ]]; then
echo " yes, do it"
else
echo " no, do not do it"
fi
echo -n "arg with multiple values: "
for a in "${MULTIPLE[@]}"; do
echo -n "[$a] "
done

If you happen to be using Mono, then you might be interested to know that Mono 2.8 (to be released later this year) will have a performance counter which reports the physical memory size on all the platforms Mono runs on (including Windows). You would retrieve the value of the counter using this code snippet:
using System;
using System.Diagnostics;
class app
{
static void Main ()
{
var pc = new PerformanceCounter ("Mono Memory", "Total Physical Memory");
Console.WriteLine ("Physical RAM (bytes): {0}", pc.RawValue);
}
}
If you are interested in C code which provides the performance counter, it can be found here.
Sadly, mod_evasive
won't work as expected when used in non-prefork configurations (recent apache setups are mainly MPM)
Whenever you start Visual Studio run it as administrator. It works for me.
I defined two functions in Site.Master:
<script type="text/javascript">
var spinnerVisible = false;
function showProgress() {
if (!spinnerVisible) {
$("div#spinner").fadeIn("fast");
spinnerVisible = true;
}
};
function hideProgress() {
if (spinnerVisible) {
var spinner = $("div#spinner");
spinner.stop();
spinner.fadeOut("fast");
spinnerVisible = false;
}
};
</script>
And special section:
<div id="spinner">
Loading...
</div>
Visual style is defined in CSS:
div#spinner
{
display: none;
width:100px;
height: 100px;
position: fixed;
top: 50%;
left: 50%;
background:url(spinner.gif) no-repeat center #fff;
text-align:center;
padding:10px;
font:normal 16px Tahoma, Geneva, sans-serif;
border:1px solid #666;
margin-left: -50px;
margin-top: -50px;
z-index:2;
overflow: auto;
}
System.getProperty("user.name")
Every time setColor
gets hit, you are setting count = 1. You would need to define count
outside of the scope of the function. Example:
var count=1;
function setColor(btn, color){
var property = document.getElementById(btn);
if (count == 0){
property.style.backgroundColor = "#FFFFFF"
count=1;
}
else{
property.style.backgroundColor = "#7FFF00"
count=0;
}
}
I happened to come up with a solution very similar to @Andrew, only DRY
class MetaFoo(type):
def __new__(mc1, name, bases, nmspc):
nmspc.update({'thingy': MetaFoo.thingy})
return super(MetaFoo, mc1).__new__(mc1, name, bases, nmspc)
@property
def thingy(cls):
if not inspect.isclass(cls):
cls = type(cls)
return cls._thingy
@thingy.setter
def thingy(cls, value):
if not inspect.isclass(cls):
cls = type(cls)
cls._thingy = value
class Foo(metaclass=MetaFoo):
_thingy = 23
class Bar(Foo)
_thingy = 12
This has the best of all answers:
The "metaproperty" is added to the class, so that it will still be a property of the instance
In my case, I actually customized _thingy
to be different for every child, without defining it in each class (and without a default value) by:
def __new__(mc1, name, bases, nmspc):
nmspc.update({'thingy': MetaFoo.services, '_thingy': None})
return super(MetaFoo, mc1).__new__(mc1, name, bases, nmspc)
It's a block of code which is executed when the class gets loaded by a classloader. It is meant to do initialization of static members of the class.
It is also possible to write non-static initializers, which look even stranger:
public class Foo {
{
// This code will be executed before every constructor
// but after the call to super()
}
Foo() {
}
}
64 bit version will allow a single process to use more RAM than 32 bit, however you may find that the memory footprint doubles depending on what you are storing in RAM (Integers in particular).
For example if your app requires > 2GB of RAM, so you switch from 32bit to 64bit you may find that your app is now requiring > 4GB of RAM.
Check whether all of your 3rd party modules are available in 64 bit, otherwise it may be easier to stick to 32bit in the meantime
This does the job nicely:
def urljoin(*args):
"""
Joins given arguments into an url. Trailing but not leading slashes are
stripped for each argument.
"""
return "/".join(map(lambda x: str(x).rstrip('/'), args))
select * from table where id not in (select id from table limit 10)
where id
be the key in your table.
Whammo blammo (for leading spaces):
SELECT
RIGHT(space(60) + cust_name, 60),
RIGHT(space(60) + cust_address, 60)
OR (for trailing spaces)
SELECT
LEFT(cust_name + space(60), 60),
LEFT(cust_address + space(60), 60),
Try this; bear in mind that JavaScript months are 0-indexed, whilst days are 1-indexed.
var date = new Date('2010-10-11T00:00:00+05:30');_x000D_
alert(((date.getMonth() > 8) ? (date.getMonth() + 1) : ('0' + (date.getMonth() + 1))) + '/' + ((date.getDate() > 9) ? date.getDate() : ('0' + date.getDate())) + '/' + date.getFullYear());

Add an input id to the element and do something like that:
document.getElementById('inputId').value.split(/[\\$]/).pop()
In the first two cases, you simply forgot to actually call the member function (!, it's not a value) std::vector<int>::size
like this:
#include <vector>
int main () {
std::vector<int> v;
auto size = v.size();
}
Your third call
int size = v.size();
triggers a warning, as not every return value of that function (usually a 64 bit unsigned int) can be represented as a 32 bit signed int.
int size = static_cast<int>(v.size());
would always compile cleanly and also explicitly states that your conversion from std::vector::size_type
to int
was intended.
Note that if the size of the vector
is greater than the biggest number an int
can represent, size
will contain an implementation defined (de facto garbage) value.
There are two ways to achieve what you want. Unfortunately, neither can be done using a view.
You can either create a table valued user defined function that takes the parameter you want and returns a query result
Or you can do pretty much the same thing but create a stored procedure instead of a user defined function.
For example:
the stored procedure would look like
CREATE PROCEDURE s_emp
(
@enoNumber INT
)
AS
SELECT
*
FROM
emp
WHERE
emp_id=@enoNumber
Or the user defined function would look like
CREATE FUNCTION u_emp
(
@enoNumber INT
)
RETURNS TABLE
AS
RETURN
(
SELECT
*
FROM
emp
WHERE
emp_id=@enoNumber
)

OAuth 2.0 defines a protocol, i.e. specifies how tokens are transferred, JWT defines a token format.
OAuth 2.0 and "JWT authentication" have similar appearance when it comes to the (2nd) stage where the Client presents the token to the Resource Server: the token is passed in a header.
But "JWT authentication" is not a standard and does not specify how the Client obtains the token in the first place (the 1st stage). That is where the perceived complexity of OAuth comes from: it also defines various ways in which the Client can obtain an access token from something that is called an Authorization Server.
So the real difference is that JWT is just a token format, OAuth 2.0 is a protocol (that may use a JWT as a token format).
in the file .gitmodules, I replaced string
"path = thirdsrc\boost"
with
"path = thirdsrc/boost",
and it solved! - -
rowMeans
is nice, but if you are still trying to wrap your head around the apply
family of functions, this is a good opprotunity to begin understanding it.
DF['Mean'] <- apply(DF[,2:4], 1, mean)
Notice I'm doing a slightly different assignment than the first example. This approach makes it easier to incorporate it into for loops.
You can use string formatting to do this:
print "If there was a birth every 7 seconds, there would be: %d births" % births
or you can give print
multiple arguments, and it will automatically separate them by a space:
print "If there was a birth every 7 seconds, there would be:", births, "births"
If you are using Bootstrap responsive table, just want to set the maximum width for one particular column and make text wrapping, making the the style of this column as following also works
max-width:someValue;
word-wrap:break-word
To get a type that implements io.Reader
from a []byte
slice, you can use bytes.NewReader
in the bytes
package:
r := bytes.NewReader(byteData)
This will return a value of type bytes.Reader
which implements the io.Reader
(and io.ReadSeeker
) interface.
Don't worry about them not being the same "type". io.Reader
is an interface and can be implemented by many different types. To learn a little bit more about interfaces in Go, read Effective Go: Interfaces and Types.
In XML, use:

Just simply click on your app name and look on your right, you app id should be there
For your app secret, u have to click show.
Hope that helps !
All this talk about collation seem a bit over-complicated. Why not just use something like:
IF UPPER(@@VERSION) NOT LIKE '%AZURE%'
Then your check is case insensitive whatever the collation
The ObjectiveC equivalent is:
myView.translatesAutoresizingMaskIntoConstraints = NO;
[[myView.centerXAnchor constraintEqualToAnchor:self.view.centerXAnchor] setActive:YES];
[[myView.centerYAnchor constraintEqualToAnchor:self.view.centerYAnchor] setActive:YES];
With Linq
var newList = GlobalStrings.Append(localStrings)
This helped me:
<p>Date/Time: <span id="datetime"></span></p><script>var dt = new Date();
document.getElementById("datetime").innerHTML=dt.toLocaleString();</script>
Try calling setWillNotDraw(false)
from surfaceCreated
:
public void surfaceCreated(SurfaceHolder holder) {
try {
setWillNotDraw(false);
mycam.setPreviewDisplay(holder);
mycam.startPreview();
} catch (Exception e) {
e.printStackTrace();
Log.d(TAG,"Surface not created");
}
}
@Override
protected void onDraw(Canvas canvas) {
canvas.drawRect(area, rectanglePaint);
Log.w(this.getClass().getName(), "On Draw Called");
}
and calling invalidate
from onTouchEvent
:
public boolean onTouch(View v, MotionEvent event) {
invalidate();
return true;
}
To expand on @nawfal:s answer, I use this to test objects of different types in my unit tests to compare equal property names. In my case database entity and DTO.
Used like this in my test;
Assert.IsTrue(resultDto.PublicInstancePropertiesEqual(expectedEntity));
public static bool PublicInstancePropertiesEqual<T, Z>(this T self, Z to, params string[] ignore) where T : class
{
if (self != null && to != null)
{
var type = typeof(T);
var type2 = typeof(Z);
var ignoreList = new List<string>(ignore);
var unequalProperties =
from pi in type.GetProperties(BindingFlags.Public | BindingFlags.Instance)
where !ignoreList.Contains(pi.Name)
let selfValue = type.GetProperty(pi.Name).GetValue(self, null)
let toValue = type2.GetProperty(pi.Name).GetValue(to, null)
where selfValue != toValue && (selfValue == null || !selfValue.Equals(toValue))
select selfValue;
return !unequalProperties.Any();
}
return self == null && to == null;
}
The problem was the use of incorrect quotes around the iOS version. Make sure all your quotes are ' and not ‘ or ’.
I had this problem and what solved it for me was to:
I had a similar issue and was able to resolve it by identifying which JDBC driver I intended to use. In my case, I was connecting to an Oracle database. I placed the following statement, prior to creating the connection variable.
DriverManager.registerDriver( new oracle.jdbc.driver.OracleDriver());
In C++, a derived class object can be assigned to a base class object, but the other way is not possible.
class Base { int x, y; };
class Derived : public Base { int z, w; };
int main()
{
Derived d;
Base b = d; // Object Slicing, z and w of d are sliced off
}
Object slicing happens when a derived class object is assigned to a base class object, additional attributes of a derived class object are sliced off to form the base class object.

public byte UserType
public string SelectUserType
You need to get one and set different one. Selected value can not be the same item that you are about to set.
@Html.DropDownListFor(p => p.SelectUserType, new SelectList(~~UserTypeNames, "Key", "Value",UserType))
I use Enum dictionary for my list, that's why there is "key", "value" pair.
Try this on Windows:
cmdkey /delete:LegacyGeneric:target=git:https://github.com
ColumnNames
is a property of type List<String>
so when you are setting up you need to pass a List<String>
in the Returns
call as an argument (or a func which return a List<String>
)
But with this line you are trying to return just a string
input.SetupGet(x => x.ColumnNames).Returns(temp[0]);
which is causing the exception.
Change it to return whole list:
input.SetupGet(x => x.ColumnNames).Returns(temp);
Now in c++11 I think that the best way to insert a pair in a STL map is:
typedef std::map<int, std::string> MyMap;
MyMap map;
auto& result = map.emplace(3,"Hello");
The result will be a pair with:
First element (result.first), points to the pair inserted or point to the pair with this key if the key already exist.
Second element (result.second), true if the insertion was correct or false it something went wrong.
PS: If you don´t case about the order you can use std::unordered_map ;)
Thanks!

Vector's iterators are random access iterators which means they look and feel like plain pointers.
You can access the nth element by adding n to the iterator returned from the container's begin()
method, or you can use operator []
.
std::vector<int> vec(10);
std::vector<int>::iterator it = vec.begin();
int sixth = *(it + 5);
int third = *(2 + it);
int second = it[1];
Alternatively you can use the advance function which works with all kinds of iterators. (You'd have to consider whether you really want to perform "random access" with non-random-access iterators, since that might be an expensive thing to do.)
std::vector<int> vec(10);
std::vector<int>::iterator it = vec.begin();
std::advance(it, 5);
int sixth = *it;
Just my 2 cents. This code combines two matrices or data.frames into one. If one data structure have lower number of rows then missing rows will be added with NA values.
combine.df <- function(x, y) {
rows.x <- nrow(x)
rows.y <- nrow(y)
if (rows.x > rows.y) {
diff <- rows.x - rows.y
df.na <- matrix(NA, diff, ncol(y))
colnames(df.na) <- colnames(y)
cbind(x, rbind(y, df.na))
} else {
diff <- rows.y - rows.x
df.na <- matrix(NA, diff, ncol(x))
colnames(df.na) <- colnames(x)
cbind(rbind(x, df.na), y)
}
}
df1 <- data.frame(1:10, row.names = 1:10)
df2 <- data.frame(1:5, row.names = 10:14)
combine.df(df1, df2)
You could also create an extension for this so you will be able to reuse the extension without implementing this again and again in every view controller.
import UIKit
extension UIViewController {
func hideNavigationBar(animated: Bool){
// Hide the navigation bar on the this view controller
self.navigationController?.setNavigationBarHidden(true, animated: animated)
}
func showNavigationBar(animated: Bool) {
// Show the navigation bar on other view controllers
self.navigationController?.setNavigationBarHidden(false, animated: animated)
}
}
So you can use the extension methods as below
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
hideNavigationBar(animated: animated)
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
showNavigationBar(animated: animated)
}
