If someone is still looking for an answer, for me the problem was in routes/web.php file. Example:
Route::get('/', function () {
return view('welcome');
});
It is also Route, so yeah...Just remove it if not needed and you are good to go! You should also follow answers provided from above.
Solution for me (Android Studio) :
1) Use shortcut Ctrl+Shift+Alt+S or File -> Project Structure
2) and increase the level of SDK "Compile SDK Version".
use @Id .Worked for me.Otherwise it i will throw error.It depends on is there anything missing in your entity class or repository
Try to move:
apply plugin: 'com.google.gms.google-services'
just below:
apply plugin: 'com.android.application'
In your module Gradle file, then make sure all Google service's have the version 9.0.0
.
Make sure that only this build tools is used:
classpath 'com.android.tools.build:gradle:2.1.0'
Make sure in gradle-wrapper.properties:
distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
After all above is correct, then make menu File -> Invalidate caches and restart.
Duplicate name Classes
like
class BackGroundTask extends AsyncTask<String, Void, Void> {
and
class BackgroundTask extends AsyncTask<String, Void, Void> {
When your app references exceed 65,536 methods, you encounter a build error that indicates your app has reached the limit of the Android build architecture
Multidex support prior to Android 5.0
Versions of the platform prior to Android 5.0 (API level 21) use the Dalvik runtime for executing app code. By default, Dalvik limits apps to a single classes.dex bytecode file per APK. In order to get around this limitation, you can add the multidex support library to your project:
dependencies {
implementation 'com.android.support:multidex:1.0.3'
}
Multidex support for Android 5.0 and higher
Android 5.0 (API level 21) and higher uses a runtime called ART which natively supports loading multiple DEX files from APK files. Therefore, if your minSdkVersion is 21 or higher, you do not need the multidex support library.
Avoid the 64K limit
Configure multidex in app for
If your minSdkVersion is set to 21 or higher, all you need to do is set multiDexEnabled to true in your module-level build.gradle file
android {
defaultConfig {
...
minSdkVersion 21
targetSdkVersion 28
multiDexEnabled true
}
...
}
if your minSdkVersion is set to 20 or lower, then you must use the multidex support library
android {
defaultConfig {
...
minSdkVersion 15
targetSdkVersion 28
multiDexEnabled true
}
...
}
dependencies {
compile 'com.android.support:multidex:1.0.3'
}
Override the Application class, change it to extend MultiDexApplication (if possible) as follows:
public class MyApplication extends MultiDexApplication { ... }
add to the manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<application
android:name="MyApplication" >
...
</application>
</manifest>
I changed the target=android-26
to target=android-23
project.properties
this works great for me.
You can fix this issue by adding a project ext property googlePlayServicesVersion
to app/App_Resources/Android/app.gradle
file like this:
project.ext {
googlePlayServicesVersion = "+"
}
Just clean and retry solved for me.
Possible help
Tried as absolute last resort after exhausting all other options
I removed all memory sticks (RAM) but one. I have less memory now but its working again. I can't pretend to know why the build process always found corrupted memory, or if that's 100% the root cause - in other respects the system ran fine. Maybe this is something to try, best of luck.
I solved this issue by change to use latest buildToolsVersion
android {
//...
buildToolsVersion '26.0.2' // change from '23.0.2'
//...
}
This error is because of using more number of libraries.in my case 'compile 'com.google.android.gms:play-services-9.4.0' caused this error.To avoid this error use necessary libraries.for example if you want to use Maps in your app.Then use compile 'com.google.android.gms:play-services-maps:9.4.0'.while adding google play services dependency specify the needed libraries only.by default it includes all the libraries.
its been a while but hope it helps
For me it was just something missing from @dimens which was used in xml file it was weird that android studio didn't mention it directly in error
After a lot of surfing, i found out the problem is GC overhead (out of memory). By adding below code to my build.gradle saved my day.
android {
dexOptions {
incremental = true;
preDexLibraries = false
javaMaxHeapSize "4g" // 2g should be also OK
}
}
reference - ProcessException: org.gradle.process.internal.ExecException finished with non-zero exit value 2
I am adding it so that someone in a similar situation might find it helpful.
So, even after multiDexEnabled = true
I was getting the same error. I had no duplicate libraries. None of the above solutions worked. Upon reading the error log, I found OutOfMemError
issue to be the primary reason and thought of changing the heap size
somehow. Hence, this -
dexOptions {
preDexLibraries = false
javaMaxHeapSize "4g"
}
Where "4g" means HeapSize
of 4 GB. And it worked! I hope it does for you too.
A few comments:
import sun.misc.*;
Don't do this. It is non-standard and not guaranteed to be the same between implementations. There are other libraries with Base64 conversion available.
byte[] encVal = c.doFinal(Data.getBytes());
You are relying on the default character encoding here. Always specify what character encoding you are using: byte[] encVal = c.doFinal(Data.getBytes("UTF-8"));
Defaults might be different in different places.
As @thegrinner pointed out, you need to explicitly check the length of your byte arrays. If there is a discrepancy, then compare them byte by byte to see where the difference is creeping in.
Check your server config file /etc/mysql/my.cnf
- verify bind_address
is not set to 127.0.0.1
. Set it to 0.0.0.0
or comment it out then restart server with:
sudo service mysql restart
There is a trick, Arithmetic exceptions only happen when you are playing around with integers and only during / or % operation.
If there is any floating point number in an arithmetic operation, internally all integers will get converted into floating point. This may help you to remember things easily.
I replaced the "localhost" with IP Address (Database server's public IP Address) in the jdbc Url then it worked.
jdbcUrl = "jdbc:oracle:thin:<user>@//localhost:1521/<Service Name>";
??
jdbcUrl = "jdbc:oracle:thin:<user>@//<Public IP Address>:1521/<Service Name>";
The problem in my case was that the database name was incorrect.
I solved the problem by referring the correct database name in the field as below
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/myDatabase</property>
You've just published that private key, so now the whole world knows what it is. Hopefully that was just for testing.
EDIT: Others have noted that the openssl text header of the published key, -----BEGIN RSA PRIVATE KEY-----, indicates that it is PKCS#1. However, the actual Base64 contents of the key in question is PKCS#8. Evidently the OP copy and pasted the header and trailer of a PKCS#1 key onto the PKCS#8 key for some unknown reason. The sample code I've provided below works with PKCS#8 private keys.
Here is some code that will create the private key from that data. You'll have to replace the Base64 decoding with your IBM Base64 decoder.
public class RSAToy {
private static final String BEGIN_RSA_PRIVATE_KEY = "-----BEGIN RSA PRIVATE KEY-----\n"
+ "MIIEuwIBADAN ...skipped the rest\n"
// + ...
// + ... skipped the rest
// + ...
+ "-----END RSA PRIVATE KEY-----";
public static void main(String[] args) throws Exception {
// Remove the first and last lines
String privKeyPEM = BEGIN_RSA_PRIVATE_KEY.replace("-----BEGIN RSA PRIVATE KEY-----\n", "");
privKeyPEM = privKeyPEM.replace("-----END RSA PRIVATE KEY-----", "");
System.out.println(privKeyPEM);
// Base64 decode the data
byte [] encoded = Base64.decode(privKeyPEM);
// PKCS8 decode the encoded RSA private key
PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(encoded);
KeyFactory kf = KeyFactory.getInstance("RSA");
PrivateKey privKey = kf.generatePrivate(keySpec);
// Display the results
System.out.println(privKey);
}
}
Wow it took me forever to figure out this one. For some reason changing the attribute [assembly: AssemblyCompany("CompanyName")]
at AssemblyInfo.cs
made this error disappear. I was referencing a project that had a different value for the attribute [assembly: AssemblyCompany("CompanyName")]
. I maked sure both projects had the same attribute value and it worked great!
From the Java 11 BigDecimal
docs:
When a
MathContext
object is supplied with a precision setting of 0 (for example,MathContext.UNLIMITED
), arithmetic operations are exact, as are the arithmetic methods which take noMathContext
object. (This is the only behavior that was supported in releases prior to 5.)As a corollary of computing the exact result, the rounding mode setting of a
MathContext
object with a precision setting of 0 is not used and thus irrelevant. In the case of divide, the exact quotient could have an infinitely long decimal expansion; for example, 1 divided by 3.If the quotient has a nonterminating decimal expansion and the operation is specified to return an exact result, an
ArithmeticException
is thrown. Otherwise, the exact result of the division is returned, as done for other operations.
To fix, you need to do something like this:
a.divide(b, 2, RoundingMode.HALF_UP)
where 2 is the scale and RoundingMode.HALF_UP is rounding mode
For more details see this blog post.

How To: Configure MachineKey in ASP.NET 2.0 - Web Farm Deployment Considerations
Web Farm Deployment Considerations
If you deploy your application in a Web farm, you must ensure that the configuration files on each server share the same value for validationKey and decryptionKey, which are used for hashing and decryption respectively. This is required because you cannot guarantee which server will handle successive requests.
With manually generated key values, the settings should be similar to the following example.
<machineKey validationKey="21F090935F6E49C2C797F69BBAAD8402ABD2EE0B667A8B44EA7DD4374267A75D7 AD972A119482D15A4127461DB1DC347C1A63AE5F1CCFAACFF1B72A7F0A281B" decryptionKey="ABAA84D7EC4BB56D75D217CECFFB9628809BDB8BF91CFCD64568A145BE59719F" validation="SHA1" decryption="AES" />
If you want to isolate your application from other applications on the same server, place the in the Web.config file for each application on each server in the farm. Ensure that you use separate key values for each application, but duplicate each application's keys across all servers in the farm.
In short, to set up the machine key refer the following link: Setting Up a Machine Key - Orchard Documentation.
Setting Up the Machine Key Using IIS Manager
If you have access to the IIS management console for the server where Orchard is installed, it is the easiest way to set-up a machine key.
Start the management console and then select the web site. Open the machine key configuration:
The machine key control panel has the following settings:
Uncheck "Automatically generate at runtime" for both the validation key and the decryption key.
Click "Generate Keys" under "Actions" on the right side of the panel.
Click "Apply".
and add the following line to the web.config
file in all the webservers
under system.web
tag if it does not exist.
<machineKey
validationKey="21F0SAMPLEKEY9C2C797F69BBAAD8402ABD2EE0B667A8B44EA7DD4374267A75D7
AD972A119482D15A4127461DB1DC347C1A63AE5F1CCFAACFF1B72A7F0A281B"
decryptionKey="ABAASAMPLEKEY56D75D217CECFFB9628809BDB8BF91CFCD64568A145BE59719F"
validation="SHA1"
decryption="AES"
/>
Please make sure that you have a permanent backup of the machine keys and web.config
file
You may need to handle javax.persistence.RollbackException
I had a similar problem with a different cause and therefore different solution. In my case, I actually had an error where a singleton object was having a member variable modified in a non-threadsafe way. In this case, following the accepted answers and circumventing the parallel testing would only hide the error that was actually revealed by the test. My solution, of course, is to fix the design so that I don't have this bad behavior in my code.
You need to convert your private key to PKCS8 format using following command:
openssl pkcs8 -topk8 -inform PEM -outform DER -in private_key_file -nocrypt > pkcs8_key
After this your java program can read it.
@Column(nullable = false, updatable = false)
@CreationTimestamp
private Date created_at;
this worked for me. more info
Sometimes changes made to the model or to the ORM may not reflect accurately on the database even after an execution of SchemaUpdate
.
If the error actually seems to lack a sensible explanation, try recreating the database (or at least creating a new one) and scaffolding it with SchemaExport
.
I hit this in my service fabric project after the cert used to authenticate against our key vault expired and was rotated, which changed the thumbprint. I got this error because I had missed updating the thumbprint in the applicationManifest.xml file in this block which precisely does what other answers have suggested - to given NETWORK SERVICE (which all my exes run as, standard config for azure servicefabric cluster) permissions to access the LOCALMACHINE\MY cert store location.

This limitation (of Windows) should be publicly announced! The issue for me is the combination of the following: Windows 10 + AMD CPU (with AMD-V/SMV) +/- Hyper Visor
I have no issues running: Intel (with VT-x) + Linux or AMD (with AMD-V) + Linux
Link to Android studio issue here:
https://developer.android.com/studio/run/emulator.html#accel-vm
Xamarin/Visual Studio seems to have a workaround, but I haven't tested it yet:
If you need to use Hyper-V for other emulators then I'd recommend using the Microsoft Android Emulator instead, which uses Hyper-V and can also be used with Xamarin Studio/Visual Studio. You can download it for free from here.
I will update this after I confirm it works. Wish I would have known this before purchasing a new machine.
UPDATE!! It does not work "Requires Intel ..." error message is shown
Final note:
*Must be revision F3 or grater or must be F2 with BIOS support. Presence or absence of SVM Disable or other virtualization options in the bios does not ensure presence of BIOS support. You should contact the OEM to ensure support of Hyper-V.
*Some AMD BIOS's have options to enable/disable SVM (virtualization assistance)
*Some BIOS's list this as SVM Disable and it's a double negative, i.e. you want to disable SVM disable to enable SVM.
*Some BIOS's list this as Secure Virtualization, thus enabling Secure Virtualization will enable SVM
*Must have No-Execute enabled in the BIOS, sometime this is referred to as NX or Execute Disable

sc.getConf.getAll.foreach(println)
I think you should be able to use a default route handler and redirect from there to a page outside the app, as detailed below:
const ROUTER_INSTANCE = new VueRouter({
mode: "history",
routes: [
{ path: "/", component: HomeComponent },
// ... other routes ...
// and finally the default route, when none of the above matches:
{ path: "*", component: PageNotFound }
]
})
In the above PageNotFound
component definition, you can specify the actual redirect, that will take you out of the app entirely:
Vue.component("page-not-found", {
template: "",
created: function() {
// Redirect outside the app using plain old javascript
window.location.href = "/my-new-404-page.html";
}
}
You may do it either on created
hook as shown above, or mounted
hook also.
Please note:
I have not verified the above. You need to build a production version of app, ensure that the above redirect happens. You cannot test this in vue-cli
as it requires server side handling.
Usually in single page apps, server sends out the same index.html along with app scripts for all route requests, especially if you have set <base href="/">
. This will fail for your /404-page.html
unless your server treats it as a special case and serves the static page.
Let me know if it works!
Update for Vue 3 onward:
You'll need to replace the '*'
path property with '/:pathMatch(.*)*'
if you're using Vue 3 as the old catch-all path of '*'
is no longer supported. The route would then look something like this:
{ path: '/:pathMatch(.*)*', component: PathNotFound },
See the docs for more info on this update.

I faced the same problem. My problem was that I could modify a file, but not another (both are in same project). Later I found that the file I couldn't modify was also part of another project. That another project (Unit Test) wasn't loaded, and intelligent VS debugger shows the error that assembly for this given file was not loaded, and changes aren't allowed. How weird!
Hence, I had to unload the unit-test project and continue the EnC debugging.
How abt something like this, using the standard bitset ...
#include <bitset>
#include <iostream>
template <std::size_t N>
inline void
rotate(std::bitset<N>& b, unsigned m)
{
b = b << m | b >> (N-m);
}
int main()
{
std::bitset<8> b(15);
std::cout << b << '\n';
rotate(b, 2);
std::cout << b << '\n';
return 0;
}

A slight extension to the answer given, so, hopefully useful to the asker and anyone else looking.
You can also SELECT
the values you want to delete. But watch out for the Error 1093 - You can't specify the target table for update in FROM clause.
DELETE FROM
orders_products_history
WHERE
(branchID, action) IN (
SELECT
branchID,
action
FROM
(
SELECT
branchID,
action
FROM
orders_products_history
GROUP BY
branchID,
action
HAVING
COUNT(*) > 10000
) a
);
I wanted to delete all history records where the number of history records for a single action/branch exceed 10,000. And thanks to this question and chosen answer, I can.
Hope this is of use.

Use a BigDecimal
instead of float
/double
. There are a lot of numbers which can't be represented as binary floating point (for example, 0.1
). So you either must always round the result to a known precision or use BigDecimal
.
See http://en.wikipedia.org/wiki/Floating_point for more information.

I've started using PDO because the statement support is better, in my opinion. I'm using an ActiveRecord-esque data-access layer, and it's much easier to implement dynamically generated statements. MySQLi's parameter binding must be done in a single function/method call, so if you don't know until runtime how many parameters you'd like to bind, you're forced to use call_user_func_array()
(I believe that's the right function name) for selects. And forget about simple dynamic result binding.
Most of all, I like PDO because it's a very reasonable level of abstraction. It's easy to use it in completely abstracted systems where you don't want to write SQL, but it also makes it easy to use a more optimized, pure query type of system, or to mix-and-match the two.

OpenTK is an improvement over the Tao API, as it uses idiomatic C# style with overloading, strongly-typed enums, exceptions, and standard .NET types:
GL.Begin(BeginMode.Points);
GL.Color3(Color.Yellow);
GL.Vertex3(Vector3.Up);
as opposed to Tao which merely mirrors the C API:
Gl.glBegin(Gl.GL_POINTS); // double "gl" prefix
Gl.glColor3ub(255, 255, 0); // have to pass RGB values as separate args
Gl.glVertex3f(0, 1, 0); // explicit "f" qualifier
This makes for harder porting but is incredibly nice to use.
As a bonus it provides font rendering, texture loading, input handling, audio, math...
Update 18th January 2016: Today the OpenTK maintainer has stepped away from the project, leaving its future uncertain. The forums are filled with spam. The maintainer recommends moving to MonoGame or SDL2#.
Update 30th June 2020: OpenTK has had new maintainers for a while now and has an active discord community. So the previous recommendation of using another library isn't necessarily true.
This change worked for me:
// The size returned by CGImageGetWidth(imgRef) & CGImageGetHeight(imgRef) is incorrect as it doesn't respect the image orientation!
// CGImageRef imgRef = [image CGImage];
// CGFloat width = CGImageGetWidth(imgRef);
// CGFloat height = CGImageGetHeight(imgRef);
//
// This returns the actual width and height of the photo (and hence solves the problem
CGFloat width = image.size.width;
CGFloat height = image.size.height;
CGRect bounds = CGRectMake(0, 0, width, height);
The /P
switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.
Two ways I've used it... first:
SET /P variable=
When batch file reaches this point (when left blank) it will halt and wait for user input. Input then becomes variable.
And second:
SET /P variable=<%temp%\filename.txt
Will set variable to contents (the first line) of the txt file. This method won't work unless the /P
is included. Both tested on Windows 8.1 Pro, but it's the same on 7 and 10.
You can use the Positioned.fill
with Align
inside a Stack
:
Stack(
children: <Widget>[
Positioned.fill(
child: Align(
alignment: Alignment.centerRight,
child: ....
),
),
],
),
The above responses are the better, but just for completeness, when you are in a component you can access the history object inside the VueRouter with: this.$router.history. That means we can listen to changes with:
this.$router.listen((newLocation) =>{console.log(newLocation);})
I think this is mainly useful when used along with this.$router.currentRoute.path
You can check what I am talking about placing a debugger

window.addEventListener('scroll', this.handleScroll);
},
componentWillUnmount: function() {
window.removeEventListener('scroll', this.handleScroll);

itemTranslate = Math.min(0, scrollTop/3 - 60);
this.setState({
transform: itemTranslate
});
},
...
This gives handleScroll()
access to the proper scope when called from the event listener.
Also be aware you cannot do the .bind(this)
in the addEventListener
or removeEventListener
methods because they will each return references to different functions and the event will not be removed when the component unmounts.
Maybe placing the jquery.ui.widget.js

As AlienWebGuy said, you can use background-image. I'd suggest you use background, but it will need three more properties after the URL:
background: url("http://www.gentleface.com/i/free_toolbar_icons_16x16_black.png") 0 0 no-repeat;
Explanation: the two zeros are x and y positioning for the image; if you want to adjust where the background image displays, play around with these (you can use both positive and negative values, e.g: 1px or -1px).
No-repeat says you don't want the image to repeat across the entire background. This can also be repeat-x and repeat-y.
Download php5.dll (http://windows.php.net/download/) and copy it to apache/bin folder. That solved it for me (Win 7 64 bit apache 32 bit)
EDIT: Start with the non-thread safe version.
According to the RFC that introduced the operator, $a <=> $b
evaluates to:
$a == $b
$a < $b
$a > $b
which seems to be the case in practice in every scenario I've tried, although strictly the official docs only offer the slightly weaker guarantee that $a <=> $b
will return
an integer less than, equal to, or greater than zero when
$a
is respectively less than, equal to, or greater than$b
Regardless, why would you want such an operator? Again, the RFC addresses this - it's pretty much entirely to make it more convenient to write comparison functions for usort
(and the similar uasort
and uksort
).
usort
takes an array to sort as its first argument, and a user-defined comparison function as its second argument. It uses that comparison function to determine which of a pair of elements from the array is greater. The comparison function needs to return:
an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.
The spaceship operator makes this succinct and convenient:
$things = [
[
'foo' => 5.5,
'bar' => 'abc'
],
[
'foo' => 7.7,
'bar' => 'xyz'
],
[
'foo' => 2.2,
'bar' => 'efg'
]
];
// Sort $things by 'foo' property, ascending
usort($things, function ($a, $b) {
return $a['foo'] <=> $b['foo'];
});
// Sort $things by 'bar' property, descending
usort($things, function ($a, $b) {
return $b['bar'] <=> $a['bar'];
});
More examples of comparison functions written using the spaceship operator can be found in the Usefulness section of the RFC.
Ran into a similar issue.
This is linked to using a non LTS version of Ubuntu called an "End of life version". As those have discontinued support. You can check if your Ubuntu is at the end of life version on this link.
The simplest solution is to do the following two steps:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
Open the sources file /etc/apt/sources.list
and rename all the instances of us.archive or archive in
http://us.archive.ubuntu.com/ubuntu/
to
http://old-releases.ubuntu.com/ubuntu/
Also do the same for the http://security.ubuntu.com/ubuntu/dists/saucy-security/universe/binary-i386/Packages
Run sudo apt-get update
after doing the above.
That should fix the issue.
Warning: Please update your ubuntu to an LTS version as soon as possible otherwise you won't be getting the latest security patches. This is definitely not a solution that you would deploy on production machines.
Yes, what you are asking for is called AJAX or XMLHttpRequest. You can either use a library like jQuery to simplify making the call (due to cross-browser compatibility issues), or write your own handler.
In jQuery:
$.GET('url.asp', {data: 'here'}, function(data){ /* what to do with the data returned */ })
In plain vanilla javaScript (from w3c):
var xmlhttp;
function loadXMLDoc(url)
{
xmlhttp=null;
if (window.XMLHttpRequest)
{// code for all new browsers
xmlhttp=new XMLHttpRequest();
}
else if (window.ActiveXObject)
{// code for IE5 and IE6
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
if (xmlhttp!=null)
{
xmlhttp.onreadystatechange=state_Change;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}
else
{
alert("Your browser does not support XMLHTTP.");
}
}
function state_Change()
{
if (xmlhttp.readyState==4)
{// 4 = "loaded"
if (xmlhttp.status==200)
{// 200 = OK
//xmlhttp.data and shtuff
// ...our code here...
}
else
{
alert("Problem retrieving data");
}
}
}
Ruby performs well for developer productivity. Ruby by nature forces test driven development because of the lack of types. Ruby performs well when used as a high level wrapper for C libraries. Ruby also performs well during long running processes when it is JIT-compiled to machine code via JVM or Rbx VM. Ruby does not perform well when it is required to crunch numbers in a short time with pure ruby code.
You can't wrap that text as it's unbroken without any spaces. You need a JavaScript or server side solution which splits the string after a few characters.
EDIT
You need to add this property in CSS.

I guess problem is in width attributes in table and td remove 'px' for example
<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">
Should be
<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">
your google-services.json package name must match your build.gradle applicationId (applicationId "your package name")

Copy your images into the assets folder. Angular can only access static files like images and config files from assets folder.
Try like this: <img src="assets/img/myimage.png">
I made this for a webservice to requerst on URL, using a Gson lib:
Client:
public EstabelecimentoList getListaEstabelecimentoPorPromocao(){
EstabelecimentoList estabelecimentoList = new EstabelecimentoList();
try{
URL url = new URL("http://" + Conexao.getSERVIDOR()+ "/cardapio.online/rest/recursos/busca_estabelecimento_promocao_android");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
if (con.getResponseCode() != 200) {
throw new RuntimeException("HTTP error code : "+ con.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader((con.getInputStream())));
estabelecimentoList = new Gson().fromJson(br, EstabelecimentoList.class);
con.disconnect();
} catch (IOException e) {
e.printStackTrace();
}
return estabelecimentoList;
}
This worked. The first row had column names in it.

Check you have installed latest version of chrome brwoser-> chromium-browser -version
If not, install latest version of chrome sudo apt-get install chromium-browser
get appropriate version of chrome driver from here
Unzip the chromedriver.zip
Move the file to /usr/bin
directory sudo mv chromedriver /usr/bin
Goto /usr/bin
directory cd /usr/bin
Now, you would need to run something like sudo chmod a+x chromedriver
to mark it executable.
finally you can execute the code.

For what its worth, COALESCE is similiar but
IFNULL(expr1, default)
is the exact match you're looking for in DB2.
COALESCE allows multiple arguments, returning the first NON NULL expression, whereas IFNULL only permits the expression and the default.
Thus
SELECT product.ID, IFNULL(product.Name, "Internal") AS ProductName
FROM Product
Gives you what you're looking for as well as the previous answers, just adding for completeness.
Encountered the same SSL error while doing a pip install after a fresh anaconda installation. What helped was activating the base environment before doing the pip install.
Do an activate base

Mocking of static methods in Mockito is possible since Mockito 3.4.0. For more details see:
https://github.com/mockito/mockito/releases/tag/v3.4.0
https://github.com/mockito/mockito/issues/1013.
In your case, something like this:
@Test
public void testStaticMockWithVerification() throws SQLException {
try (MockedStatic<DriverManager> dummy = Mockito.mockStatic(DriverManager.class)) {
DatabaseConnectionFactory factory = new MySQLDatabaseConnectionFactory();
dummy.when(() -> DriverManager.getConnection("arg1", "arg2", "arg3"))
.thenReturn(new Connection() {/*...*/});
factory.getConnection();
dummy.verify(() -> DriverManager.getConnection(eq("arg1"), eq("arg2"), eq("arg3")));
}
}
NOTE: this feature requires mockito-inline dependency.
Simple answer that works for all browsers:
let origin;
if (!window.location.origin) {
origin = window.location.protocol + "//" + window.location.hostname +
(window.location.port ? ':' + window.location.port: '');
}
origin = window.location.origin;
$user_agent = 'yandeX';
$bots = ['Google','Yahoo','Yandex'];
foreach($bots as $b){
if( stripos( $user_agent, $b ) !== false ) return $b;
}
returns true if subject is between low and high (inclusive)
$between = function( $low, $high, $subject ) {
if( $subject < $low ) return false;
if( $subject > $high ) return false;
return true;
};
if( $between( 0, 100, $givenNumber )) {
// do whatever...
}
looks cleaner to me
I just found my own solution to this problem, or at least my problem.
I was using justify-content: space-around
instead of justify-content: space-between;
.
This way the end elements will stick to the top and bottom, and you could have custom margins if you wanted.
There are Python libraries that can recognize files based on their content (usually a header / magic number) and that don't rely on the file name or extension.
If you're addressing many different file types, you can use python-magic
. That's just a Python binding for the well-established magic
library. This has a good reputation and (small endorsement) in the limited use I've made of it, it has been solid.
There are also libraries for more specialized file types. For example, the Python standard library has the imghdr
module that does the same thing just for image file types.
If you need dependency-free (pure Python) file type checking, see filetype
.
Here is the complete solution for directly integrating a report-viewer control (as well as any asp.net server side control) in an MVC .aspx view, which will also work on a report with multiple pages (unlike Adrian Toman's answer) and with AsyncRendering set to true, (based on "Pro ASP.NET MVC Framework" by Steve Sanderson).
What one needs to do is basically:
Add a form with runat = "server"
Add the control, (for report-viewer controls it can also sometimes work even with AsyncRendering="True" but not always, so check in your specific case)
Add server side scripting by using script tags with runat = "server"
Override the Page_Init event with the code shown below, to enable the use of PostBack and Viewstate
Here is a demonstration:
<form ID="form1" runat="server">
<rsweb:ReportViewer ID="ReportViewer1" runat="server" />
</form>
<script runat="server">
protected void Page_Init(object sender, EventArgs e)
{
Context.Handler = Page;
}
//Other code needed for the report viewer here
</script>
It is of course recommended to fully utilize the MVC approach, by preparing all needed data in the controller, and then passing it to the view via the ViewModel.
This will allow reuse of the View!
However this is only said for data this is needed for every post back, or even if they are required only for initialization if it is not data intensive, and the data also has not to be dependent on the PostBack and ViewState values.
However even data intensive can sometimes be encapsulated into a lambda expression and then passed to the view to be called there.
A couple of notes though:
The best way to always render a link properly is with the css as follows:
a {cursor: pointer !important}
One should avoid to follow un-necessary things like mentioned in the thread.
Just wrap the button label in an extra span and add class="align-middle"
to both (the icon and the label). This will center your icon with text vertical.
<button id="edit-listing-form-house_Continue"
class="btn btn-large btn-primary"
style=""
value=""
name="Continue"
type="submit">
<span class="align-middle">Continue</span>
<i class="icon-ok align-middle" style="font-size:40px;"></i>
Actually you can do this.
$state.go("state-name", {param-name: param-value}, {location: false, inherit: false});
This is the official documentation about options in state.go
Everything is described there and as you can see this is the way to be done.
INFORMATION_SCHEMA
is your friend. It has all kinds of views that show all kinds of schema information. Check your system views. You will find you have three views dealing with constraints, one being CHECK_CONSTRAINTS
.
System.exit(0)
terminates the JVM. In simple examples like this it is difficult to percieve the difference. The parameter is passed back to the OS and is normally used to indicate abnormal termination (eg some kind of fatal error), so if you called java from a batch file or shell script you'd be able to get this value and get an idea if the application was successful.
It would make a quite an impact if you called System.exit(0)
on an application deployed to an application server (think about it before you try it).
Yes, you may use both ways. If you just want to separate the elements and show they in separated lines, a list is simpler:
set list=A B C D
A list of values separated by space may be easily processed by for
command:
(for %%a in (%list%) do (
echo %%a
echo/
)) > theFile.txt
You may also create an array this way:
setlocal EnableDelayedExpansion
set n=0
for %%a in (A B C D) do (
set vector[!n!]=%%a
set /A n+=1
)
and show the array elements this way:
(for /L %%i in (0,1,3) do (
echo !vector[%%i]!
echo/
)) > theFile.txt
For further details about array management in Batch files, see: Arrays, linked lists and other data structures in cmd.exe (batch) script
ATTENTION! You must know that all characters included in set
command are inserted in the variable name (at left of equal sign), or in the variable value. For example, this command:
set list = "A B C D"
create a variable called list
(list-space) with the value "A B C D"
(space, quote, A, etc). For this reason, it is a good idea to never insert spaces in set
commands. If you need to enclose the value in quotes, you must enclose both the variable name and its value:
set "list=A B C D"
PS - You should NOT use ECHO.
in order to left blank lines! An alternative is ECHO/
. For further details about this point, see: http://www.dostips.com/forum/viewtopic.php?f=3&t=774

import java.text.SimpleDateFormat
String newDateAdded = "2018-11-11T09:30:31"
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss")
Date dateAdded = dateFormat.parse(newDateAdded)
println(dateAdded)
The output looks like
Sun Nov 11 09:30:31 GMT 2018
In your example, we could adjust a bit to meet your need. If I were you, I will do:
String datePattern = "d/M/yyyy H:m:s"
String theDate = "28/09/2010 16:02:43"
SimpleDateFormat df = new SimpleDateFormat(datePattern)
println df.parse(theDate)
I hope this would help you much.
With git there is a https format
https://github.com/equivalent/we_demand_serverless_ruby.git
This format accepts User + password
https://bot-user:[email protected]/equivalent/we_demand_serverless_ruby.git
So what you can do is create a new user that will be used just as a bot,
add only enough permissions that he can just read the repository you
want to load in NPM modules and just have that directly in your
packages.json
Github > Click on Profile > Settings > Developer settings > Personal access tokens > Generate new token
In Select Scopes part, check the on repo: Full control of private repositories
This is so that token can access private repos that user can see
Now create new group in your organization, add this user to the group and add only repositories that you expect to be pulled this way (READ ONLY permission !)
You need to be sure to push this config only to private repo
Then you can add this to your / packages.json (bot-user is name of user, xxxxxxxxx is the generated personal token)
// packages.json
{
// ....
"name_of_my_lib": "https://bot-user:[email protected]/ghuser/name_of_my_lib.git"
// ...
}

Flex layout modes are not (fully) natively supported in IE yet. IE10 implements the "tween" version of the spec which is not fully recent, but still works.
https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes
This CSS-Tricks article has some advice on cross-browser use of flexbox (including IE): http://css-tricks.com/using-flexbox/
edit: after a bit more research, IE10 flexbox layout mode implemented current to the March 2012 W3C draft spec: http://www.w3.org/TR/2012/WD-css3-flexbox-20120322/
The most current draft is a year or so more recent: http://dev.w3.org/csswg/css-flexbox/
If the stashed files need to merge with the current version so use the previous ways using diff. Otherwise you might use git pop
for unstashing them, git add fileWantToKeep
for staging your file, and do a git stash save --keep-index
, for stashing everything except what is on stage.
Remember that the difference of this way with the previous ones is that it "pops" the file from stash. The previous answers keep it git checkout stash@{0} -- <filename>
so it goes according to your needs.
Multiple commands' output can be redirected. This works for either the command line or most usefully in a bash script. The -s
directs the password prompt to the screen.
Hereblock cmds stdout/stderr are sent to seperate files and nothing to display.
sudo -s -u username <<'EOF' 2>err 1>out
ls; pwd;
EOF
Hereblock cmds stdout/stderr are sent to a single file and display.
sudo -s -u username <<'EOF' 2>&1 | tee out
ls; pwd;
EOF
Hereblock cmds stdout/stderr are sent to separate files and stdout to display.
sudo -s -u username <<'EOF' 2>err | tee out
ls; pwd;
EOF
Depending on who you are(whoami) and username a password may or may not be required.

Works with python 3 (should work with python 2, but I haven't test it) and PyQt5.
Minimal working example. Copy it to the python shell and get the result.
from PyQt5.QtWidgets import QApplication
app = QApplication([])
screen = app.primaryScreen()
screenshot = screen.grabWindow(QApplication.desktop().winId())
screenshot.save('/tmp/screenshot.png')
Assembly.GetExecutingAssembly().Location
WebRequest request = WebRequest.Create("http://www.google.com");
try
{
request.GetResponse();
}
catch //If exception thrown then couldn't get response from address
{
MessageBox.Show("The URL is incorrect");`
}
This worked for me:
Check the current role you are logged into by using: SELECT CURRENT_USER, SESSION_USER;
Note: It must match with Owner of the schema.
Schema | Name | Type | Owner
--------+--------+-------+----------
If the owner is different, then give all the grants to the current user role from the admin role by :
GRANT 'ROLE_OWNER' to 'CURRENT ROLENAME';
Then try to execute the query, it will give the output as it has access to all the relations now.
After clicking on Properties of any installer(.exe) which block your application to install (Windows Defender SmartScreen prevented an unrecognized app ) for that issue i found one solution
- Right click on installer(.exe)
- Select properties option.
- Click on checkbox to check Unblock at the bottom of Properties.
This solution work for Heroku CLI (heroku-x64) installer(.exe)
You might also want to have the client-side function return false.
<asp:LinkButton runat="server" id="button" Text="Click Me" OnClick="myfunction();return false;" AutoPostBack="false" />
You might also consider:
<span runat="server" id="clickableSpan" onclick="myfunction();" class="clickable">Click Me</span>
I use the clickable class to set things like pointer, color, etc. so that its appearance is similar to an anchor tag, but I don't have to worry about it getting posted back or having to do the href="javascript:void(0);" trick.
Some useful links that will help you:
for horizontaly centering you can have something like this:

Because your update
uses PUT method, {entryId: $scope.entryId}
is considered as data, to tell angular generate from the PUT data, you need to add params: {entryId: '@entryId'}
when you define your update
, which means
return $resource('http://localhost\\:3000/realmen/:entryId', {}, {
query: {method:'GET', params:{entryId:''}, isArray:true},
post: {method:'POST'},
update: {method:'PUT', params: {entryId: '@entryId'}},
remove: {method:'DELETE'}
});
Fix: Was missing a closing curly brace on the update line.
I got somewhere with the following method:
var value = 123456789.9876543 // i.e. some decimal number
var num2 = value.toString().split('.');
var thousands = num2[0].split('').reverse().join('').match(/.{1,3}/g).join(',');
var decimals = (num2[1]) ? '.'+num2[1] : '';
var answer = thousands.split('').reverse().join('')+decimals;
Using split-reverse-join is a sneaky way of working from the back of the string to the front, in groups of 3. There may be an easier way to do that, but it felt intuitive.

Simple:
byte[] data = Convert.FromBase64String(encodedString);
string decodedString = Encoding.UTF8.GetString(data);
use DECIMAL()
or NUMERIC()
as they are fixed precision and scale numbers.

Scrollbar CSS styles are an oddity invented by Microsoft developers. They are not part of the W3C standard for CSS and therefore most browsers just ignore them.
If you want to do it within the form's __init__
method for some reason, you can manipulate the initial
dict:
class MyForm(forms.Form):
my_field = forms.CharField(max_length=255)
def __init__(self, *args, **kwargs):
super(MyForm, self).__init__(*args, **kwargs)
self.initial['my_field'] = 'Initial value'
I used requests-mock for writing tests for separate module:
# module.py
import requests
class A():
def get_response(self, url):
response = requests.get(url)
return response.text
And the tests:
# tests.py
import requests_mock
import unittest
from module import A
class TestAPI(unittest.TestCase):
@requests_mock.mock()
def test_get_response(self, m):
a = A()
m.get('http://aurl.com', text='a response')
self.assertEqual(a.get_response('http://aurl.com'), 'a response')
m.get('http://burl.com', text='b response')
self.assertEqual(a.get_response('http://burl.com'), 'b response')
m.get('http://curl.com', text='c response')
self.assertEqual(a.get_response('http://curl.com'), 'c response')
if __name__ == '__main__':

The first argument to a shell script is available as the variable $1

Just add the autocomplete="new-password"

Here's a tidyverse version:
library(tidyverse)
data(diamonds)
(as.data.frame(table(diamonds$cut)) %>% rename(Count=1,Freq=2) %>% mutate(Perc=100*Freq/sum(Freq)))
Or if you want a handy function:
getPercentages <- function(df, colName) {
df.cnt <- df %>% select({{colName}}) %>%
table() %>%
as.data.frame() %>%
rename({{colName}} :=1, Freq=2) %>%
mutate(Perc=100*Freq/sum(Freq))
}
Now you can do:
diamonds %>% getPercentages(cut)
or this:
df=diamonds %>% group_by(cut) %>% group_modify(~.x %>% getPercentages(clarity))
ggplot(df,aes(x=clarity,y=Perc))+geom_col()+facet_wrap(~cut)
As of PHP 8.0 you can use even cleaner way to catch your exceptions when you don't need to output the content of the error (from variable $e
). However you must replace default Exception
with Throwable
.
try {
/* something */
} catch (AError | BError) {
handler1()
} catch (Throwable) {
handler2()
}
color
and fill
are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:
d + scale_color_manual(values=c("#CC6666", "#9999CC"))
is what you want.

Use transform: rotate(90deg)
:
#container_2 {_x000D_
border: 1px solid;_x000D_
padding: .5em;_x000D_
width: 5em;_x000D_
height: 5em;_x000D_
transition: .3s all; /* rotate gradually instead of instantly */_x000D_
}_x000D_
_x000D_
#container_2:hover {_x000D_
-webkit-transform: rotate(90deg); /* to support Safari and Android browser */_x000D_
-ms-transform: rotate(90deg); /* to support IE 9 */_x000D_
transform: rotate(90deg);_x000D_
}
_x000D_
<div id="container_2">This box should be rotated 90° on hover.</div>
_x000D_
Click "Run code snippet", then hover over the box to see the effect of the transform.
Realistically, no other prefixed entries are needed. See Can I use CSS3 Transforms?
I faced the same issue and the complete solution is to set to false(uncheck) the "Automatically detect settings" checkbox from Lan Area Network( the same window as for Bypass proxy server for local address )
Just add @Transactional
annotation on top of your test:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"testContext.xml"})
@Transactional
public class StudentSystemTest {
By default Spring will start a new transaction surrounding your test method and @Before
/@After
callbacks, rolling back at the end. It works by default, it's enough to have some transaction manager in the context.
From: 10.3.5.4 Transaction management (bold mine):
In the TestContext framework, transactions are managed by the TransactionalTestExecutionListener. Note that
TransactionalTestExecutionListener
is configured by default, even if you do not explicitly declare@TestExecutionListeners
on your test class. To enable support for transactions, however, you must provide aPlatformTransactionManager
bean in the application context loaded by@ContextConfiguration
semantics. In addition, you must declare@Transactional
either at the class or method level for your tests.
After recently switching from Oracle to SQL Server (employer preference), I notice cursor support in SQL Server is lagging. Cursors are not always evil, sometimes required, sometimes much faster, and sometimes cleaner than trying to tune a complex query by re-arranging or adding optimization hints. The "cursors are evil" opinion is much more prominent in the SQL Server community.
So I guess this answer is to switch to Oracle or give MS a clue.
for
loop implicitly defines/opens/closes the cursor!)How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:
Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.
There should only be one element with a given id. If you're stuck with that situation, see the 2nd half of my answer for options.
How a browser behaves when you have multiple elements with the same id (illegal HTML) is not defined by specification. You could test all the browsers and find out how they behave, but it's unwise to use this configuration or rely on any particular behavior.
Use classes if you want multiple objects to have the same identifier.
<div>
<span class="a">1</span>
<span class="a">2</span>
<span>3</span>
</div>
$(function() {
var w = $("div");
console.log($(".a").length); // 2
console.log($("body .a").length); // 2
console.log($(".a", w).length); // 2
});
If you want to reliably look at elements with IDs that are the same because you can't fix the document, then you will have to do your own iteration as you cannot rely on any of the built in DOM functions.
You could do so like this:
function findMultiID(id) {
var results = [];
var children = $("div").get(0).children;
for (var i = 0; i < children.length; i++) {
if (children[i].id == id) {
results.push(children[i]);
}
}
return(results);
}
Or, using jQuery:
$("div *").filter(function() {return(this.id == "a");});
jQuery working example: http://jsfiddle.net/jfriend00/XY2tX/.
As to Why you get different results, that would have to do with the internal implementation of whatever piece of code was carrying out the actual selector operation. In jQuery, you could study the code to find out what any given version was doing, but since this is illegal HTML, there is no guarantee that it will stay the same over time. From what I've seen in jQuery, it first checks to see if the selector is a simple id like #a
and if so, just used document.getElementById("a")
. If the selector is more complex than that and querySelectorAll()
exists, jQuery will often pass the selector off to the built in browser function which will have an implementation specific to that browser. If querySelectorAll()
does not exist, then it will use the Sizzle selector engine to manually find the selector which will have it's own implementation. So, you can have at least three different implementations all in the same browser family depending upon the exact selector and how new the browser is. Then, individual browsers will all have their own querySelectorAll()
implementations. If you want to reliably deal with this situation, you will probably have to use your own iteration code as I've illustrated above.
The above code works well but if you want to navigate from an NSObject
class, where you can not use self.present
:
let storyBoard = UIStoryboard(name:"Main", bundle: nil)
if let conVC = storyBoard.instantiateViewController(withIdentifier: "SoundViewController") as? SoundViewController,
let navController = UIApplication.shared.keyWindow?.rootViewController as? UINavigationController {
navController.pushViewController(conVC, animated: true)
}

You can try the country restriction
function initialize() {
var options = {
types: ['(cities)'],
componentRestrictions: {country: "us"}
};
var input = document.getElementById('searchTextField');
var autocomplete = new google.maps.places.Autocomplete(input, options);
}
ISO 3166-1 alpha-2 can be used to restrict results to specific groups. Currently, you can use componentRestrictions to filter by country.
The country must be passed as as a two character, ISO 3166-1 Alpha-2 compatible country code.
You can also use the constant service as such. Defining the function outside of the constant call allows it to be recursive as well.
function doSomething( a, b ) {
return a + b;
};
angular.module('moduleName',[])
// Define
.constant('$doSomething', doSomething)
// Usage
.controller( 'SomeController', function( $doSomething ) {
$scope.added = $doSomething( 100, 200 );
})
;
This should do the trick:
public static int[] addPos(int[] a, int pos, int num) {
int[] result = new int[a.length];
for(int i = 0; i < pos; i++)
result[i] = a[i];
result[pos] = num;
for(int i = pos + 1; i < a.length; i++)
result[i] = a[i - 1];
return result;
}
Where a
is the original array, pos
is the position of insertion, and num
is the number to be inserted.
H vs h is difference between 24 hour vs 12 hour format.

It's simple. On the sender side, use Intent.putExtra
:
Intent myIntent = new Intent(A.this, B.class);
myIntent.putExtra("intVariableName", intValue);
startActivity(myIntent);

:
Intent mIntent = getIntent();
int intValue = mIntent.getIntExtra("intVariableName", 0);

Decode the string to Unicode. Assuming it's UTF-8-encoded:
str.decode("utf-8")
Call the replace
method and be sure to pass it a Unicode string as its first argument:
str.decode("utf-8").replace(u"\u2022", "*")
Encode back to UTF-8, if needed:
str.decode("utf-8").replace(u"\u2022", "*").encode("utf-8")
(Fortunately, Python 3 puts a stop to this mess. Step 3 should really only be performed just prior to I/O. Also, mind you that calling a string str
shadows the built-in type str
.)
JetBrains offer a reasonable explanation,
"Ad-hoc conversion of data structures to text is largely dependent on the current culture, and may lead to unintended results when the code is executed on a machine whose locale differs from that of the original developer. To prevent ambiguities, ReSharper warns you of any instances in code where such a problem may occur."
but if I am working on a site I know will be in English only, I just ignore the suggestion.
If you are looking for an objective analysis of both the editors, look at their origins and the philosophy behind their respective designs. Think, which one would suit you better and learn it (and learn it and learn it, because it takes time before you being to discover its true utility as against any IDE). An Introduction to Display Editing with Vi was written by Bill Joy and Mark Horton and he explains why he choose modal design and rationale for various key strokes ( it helps me to remember that CTRL-W +W (will switch to next Window and it will same for CTRL W+ CTRL W, just in case you held the CTRL key for a longer duration.
Here is a link to Emacs timeline and has the reference to Multics Emacs paper. Hereis RMS paper on Emacs, where I see the stress is on a programmable text editor (even way back in 1981 and before).
I have not read the emacs papers, but have read Bill Joy's vi paper a couple of times. Both are old, but still you will get the philosophy and you might choose to use the current tool (vim 7.x or emacs 25?)
Edit: I forgot to mention that it takes patience and imagination to read both these papers as it takes you back in time while reading it. But it is worth.
I ended up using BackgroundWorker, it is definitely asynchronous unlike some of the above solutions, it handles returning to the GUI thread for you, and it is very easy to understand.
It is also very easy to handle exceptions, as they end up in the RunWorkerCompleted method, but make sure you read this: Unhandled exceptions in BackgroundWorker
I used WebClient but obviously you could use HttpWebRequest.GetResponse if you wanted.
var worker = new BackgroundWorker();
worker.DoWork += (sender, args) => {
args.Result = new WebClient().DownloadString(settings.test_url);
};
worker.RunWorkerCompleted += (sender, e) => {
if (e.Error != null) {
connectivityLabel.Text = "Error: " + e.Error.Message;
} else {
connectivityLabel.Text = "Connectivity OK";
Log.d("result:" + e.Result);
}
};
connectivityLabel.Text = "Testing Connectivity";
worker.RunWorkerAsync();
Now you want to do from binary string to Decimal but Afterword, You might be needed contrary method. It's down below.
public static String decimalToBinaryString(int value) {
String str = "";
while(value > 0) {
if(value % 2 == 1) {
str = "1"+str;
} else {
str = "0"+str;
}
value /= 2;
}
return str;
}
if you are getting your values from ajax, before calling
$("#select_location_id").val(value);_x000D_
$("#select_location_id").select2().trigger('change');
_x000D_
confirm that the ajax call has completed, using the jquery function when
$.when(ajax1(), ajax2(), ajax3(), ajax4()).done(function(a1, a2, a3, a4){_x000D_
// the code here will be executed when all four ajax requests resolve._x000D_
// a1, a2, a3 and a4 are lists of length 3 containing the response text,_x000D_
// status, and jqXHR object for each of the four ajax calls respectively._x000D_
});

You could try hbase api methods!
org.apache.hadoop.hbase.client.coprocessor.AggregationClient
Here's an alternative solution - since in most browsers the navigation controls (the nav bar, tabs, etc.) are located above the page content area, you can detect the mouse pointer leaving the page via the top and display a "before you leave" dialog. It's completely unobtrusive and it allows you to interact with the user before they actually perform the action to leave.
$(document).bind("mouseleave", function(e) {
if (e.pageY - $(window).scrollTop() <= 1) {
$('#BeforeYouLeaveDiv').show();
}
});
The downside is that of course it's a guess that the user actually intends to leave, but in the vast majority of cases it's correct.
With Eclipse Galileo you go to Eclipse -> Preferences menu item, then select Java and Compiler in the dialog.
Now it still may show compiler compliance level at 1.6, yet you still see this problem. So now select the link "Configure Project Specific Settings..." and in there you'll see the project is set to 1.5, now change this to 1.6. You'll need to do this for all affected projects.
This byzantine menu / dialog interface is typical of Eclipse's poor UI design.
Here is a version with optimization. All the solutions above would require pig to read and write full tuple when counting, this script below just write '1'-s

X = FOREACH $inBag generate 1;
$result = FOREACH (GROUP X ALL PARALLEL 1) GENERATE '$name', COUNT(X);
};
The use it like
xxx = row_count(rows, 'rows_count');
Try this
$str = '<option value="123">abc</option>
<option value="123">aabbcc</option>';
preg_match_all("#<option.*?>([^<]+)</option>#", $str, $foo);

print "not = $var\n";

I put the /assets/www/index.html under app/src/main/assets directory. (take care AndroidStudio has different perspectives like Project or Android)
use super.loadUrl("file:///android_asset/www/index.html"); instead of super.loadUrl("file:///android_assets/www/index.html"); (no s)
First of all, the provided long code:
<xsl:choose>
<xsl:when test="OU_NAME='OU_ADDR1'"> --comparing two elements coming from XML
<!--remove if adrees already contain operating unit name <xsl:value-of select="OU_NAME"/> <fo:block/>-->
<xsl:if test="OU_ADDR1 !='' ">
<xsl:value-of select="OU_ADDR1"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR2 !='' ">
<xsl:value-of select="OU_ADDR2"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR3 !='' ">
<xsl:value-of select="OU_ADDR3"/>
<fo:block/>
</xsl:if>
<xsl:if test="OU_TOWN_CITY !=''">
<xsl:value-of select="OU_TOWN_CITY"/>,
<fo:leader leader-pattern="space" leader-length="2.0pt"/>
</xsl:if>
<xsl:value-of select="OU_REGION2"/>
<fo:leader leader-pattern="space" leader-length="3.0pt"/>
<xsl:value-of select="OU_POSTALCODE"/>
<fo:block/>
<xsl:value-of select="OU_COUNTRY"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="OU_NAME"/>
<fo:block/>
<xsl:if test="OU_ADDR1 !='' ">
<xsl:value-of select="OU_ADDR1"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR2 !='' ">
<xsl:value-of select="OU_ADDR2"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR3 !='' ">
<xsl:value-of select="OU_ADDR3"/>
<fo:block/>
</xsl:if>
<xsl:if test="OU_TOWN_CITY !=''">
<xsl:value-of select="OU_TOWN_CITY"/>,
<fo:leader leader-pattern="space" leader-length="2.0pt"/>
</xsl:if>
<xsl:value-of select="OU_REGION2"/>
<fo:leader leader-pattern="space" leader-length="3.0pt"/>
<xsl:value-of select="OU_POSTALCODE"/>
<fo:block/>
<xsl:value-of select="OU_COUNTRY"/>
</xsl:otherwise>
</xsl:choose>
is equivalent to this, much shorter code:
<xsl:if test="not(OU_NAME='OU_ADDR1)'">
<xsl:value-of select="OU_NAME"/>
</xsl:if>
<xsl:if test="OU_ADDR1 !='' ">
<xsl:value-of select="OU_ADDR1"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR2 !='' ">
<xsl:value-of select="OU_ADDR2"/>
<fo:block/>
</xsl:if>
<xsl:if test="LE_ADDR3 !='' ">
<xsl:value-of select="OU_ADDR3"/>
<fo:block/>
</xsl:if>
<xsl:if test="OU_TOWN_CITY !=''">
<xsl:value-of select="OU_TOWN_CITY"/>,
<fo:leader leader-pattern="space" leader-length="2.0pt"/>
</xsl:if>
<xsl:value-of select="OU_REGION2"/>
<fo:leader leader-pattern="space" leader-length="3.0pt"/>
<xsl:value-of select="OU_POSTALCODE"/>
<fo:block/>
<xsl:value-of select="OU_COUNTRY"/>
Now, to your question:
how to compare two elements coming from xml as string
In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator =
and the function not()
together with the operator =
.
$str1 = $str2
evaluates to true()
exactly when the string $str1
is equal to the string $str2
.
not($str1 = $str2)
evaluates to true()
exactly when the string $str1
is not equal to the string $str2
.
There is also the !=
operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.
Now, the rules for comparing two element nodes are similar:
$el1 = $el2
evaluates to true()
exactly when the string value of $el1
is equal to the string value of $el2
.
not($el1 = $el2)
evaluates to true()
exactly when the string value of $el1
is not equal to the string value of $el2
.
However, if one of the operands of =
is a node-set, then
$ns = $str
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string $str
$ns1 = $ns2
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string value of some node from $ns2
Therefore, the expression:
OU_NAME='OU_ADDR1'
evaluates to true()
only when there is at least one element child of the current node that is named OU_NAME
and whose string value is the string 'OU_ADDR1'.
This is obviously not what you want!
Most probably you want:
OU_NAME=OU_ADDR1
This expression evaluates to true
exactly there is at least one OU_NAME
child of the current node and one OU_ADDR1
child of the current node with the same string value.
Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt
, le
, eq
, gt
, ge
and the inherited from XPath 1.0 general comparison operator =
.
Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.
those scripts don't accomplish all the problem...Try this better:
du -ha | grep -i -o "\./.*" | grep -v "\.svn\|another_file\|another_folder" | xargs grep -i -n "$1"
this script is so better, because it uses "real" regular expressions to avoid directories from search. just separate folder or file names with "\|" on the grep -v
enjoy it! found on my linux shell! XD
This will work fine with Linq to Objects. However, some LINQ providers have difficulty running CLR methods as part of the query. This is expecially true of some database providers.
The problem is that the DB providers try to move and compile the LINQ query as a database query, to prevent pulling all of the objects across the wire. This is a good thing, but does occasionally restrict the flexibility in your predicates.
Unfortunately, without checking the provider documentation, it's difficult to always know exactly what will or will not be supported directly in the provider. It looks like your provider allows comparisons, but not the string check. I'd guess that, in your case, this is probably about as good of an approach as you can get. (It's really not that different from the IsNullOrEmpty check, other than creating the "string.Empty" instance for comparison, but that's minor.)
In Java 8 you can skip server name checking with the following code:
HttpsURLConnection.setDefaultHostnameVerifier ((hostname, session) -> true);
However this should be used only in development!
Add compat
library compilation to the build.gradle file:
compile 'com.android.support:appcompat-v7:19.+'
an helper function which still allow to use the radix
function parseIntWithFallback(s, fallback, radix) {
var parsed = parseInt(s, radix);
return isNaN(parsed) ? fallback : parsed;
}
import codecs
f=codecs.open("test.html", 'r')
print f.read()
Try something like this.
This often occurs when you build software in RHEL 7 and try to run on RHEL 6.
To update GLIBC to any version, simply download the package from
For example glibc-2.14.tar.gz in your case.
1. tar xvfz glibc-2.14.tar.gz
2. cd glibc-2.14
3. mkdir build
4. cd build
5. ../configure --prefix=/opt/glibc-2.14
6. make
7. sudo make install
8. export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH
Then try to run your software, glibc-2.14 should be linked.
No other answer covers this method, so:
I find by far the most useful, simple, and reliable method is to ask your database. For example on Linux for Postgres you might do:
sudo su postgres
tail -f /var/log/postgresql/postgresql-8.4-main.log
Each database will have slightly different procedure. In the database logs you'll see not only the raw SQL, but any connection setup or transaction overhead django is placing on the system.
Is that what you had in mind?

You can either use onclick inside the button to ensure the event is preserved, or else attach the button click handler by finding the button after it is inserted. The test.html()
call will not serialize the event.
// Create given String and make with size 30
String str = "Hello How Are You";
// Creating StringBuffer Object for right padding
StringBuffer stringBufferRightPad = new StringBuffer(str);
while (stringBufferRightPad.length() < 30) {
stringBufferRightPad.insert(stringBufferRightPad.length(), "*");
}
System.out.println("after Left padding : " + stringBufferRightPad);
System.out.println("after Left padding : " + stringBufferRightPad.toString());
// Creating StringBuffer Object for right padding
StringBuffer stringBufferLeftPad = new StringBuffer(str);
while (stringBufferLeftPad.length() < 30) {
stringBufferLeftPad.insert(0, "*");

System.out.println("after Left padding : " + stringBufferLeftPad);
System.out.println("after Left padding : " + stringBufferLeftPad.toString());
From PHP 7.1 you can do this (Accepted rfc for negative string offsets):
<?php
$silly = 'Mary had a little lamb';
echo $silly[-20];
echo $silly{-6};
echo $silly[-3];
echo $silly[-15];
echo $silly[-13];
echo $silly[-1];
echo $silly[-4];
echo $silly{-10};
echo $silly[-4];
echo $silly[-8];
echo $silly{3}; // <-- this will be deprecated in PHP 7.4
die();
I'll let you guess the output.
Also, I added this to xenonite's performance code with these results:

Using C programming on a Linux variant as a base case for examples.
Lock:
• Usually a very simple construct binary in operation either locked or unlocked
• No concept of thread ownership, priority, sequencing etc.
• Usually a spin lock where the thread continuously checks for the locks availability.
• Usually relies on atomic operations e.g. Test-and-set, compare-and-swap, fetch-and-add etc.
• Usually requires hardware support for atomic operation.
File Locks:
• Usually used to coordinate access to a file via multiple processes.
• Multiple processes can hold the read lock however when any single process holds the write lock no other process is allowed to acquire a read or write lock.
• Example : flock, fcntl etc..
Mutex:
• Mutex function calls usually work in kernel space and result in system calls.
• It uses the concept of ownership. Only the thread that currently holds the mutex can unlock it.
• Mutex is not recursive (Exception: PTHREAD_MUTEX_RECURSIVE).
• Usually used in Association with Condition Variables and passed as arguments to e.g. pthread_cond_signal, pthread_cond_wait etc.
• Some UNIX systems allow mutex to be used by multiple processes although this may not be enforced on all systems.
Semaphore:
• This is a kernel maintained integer whose values is not allowed to fall below zero.
• It can be used to synchronize processes.
• The value of the semaphore may be set to a value greater than 1 in which case the value usually indicates the number of resources available.
• A semaphore whose value is restricted to 1 and 0 is referred to as a binary semaphore.
I think you can try "Google Grid Gallery", it based on aforementioned Masonry with some additions, like styles and viewer.

Autossh is best option - checking process is not working in all cases (e.g. zombie process, network related problems)
example:
autossh -M 2323 -c arcfour -f -N -L 8088:localhost:80 host2
First, you should define "doesn't work".
Second, I assume that your table field 'content' is varchar/text, so you need to enclose it in quotes. content = '{$content}'
And last but not least: use echo mysql_error()
directly after a query to debug.

If you're using any Mac OS X version which has Notification Center, you can use the terminal-notifier gem. First install it (you may need sudo
):
gem install terminal-notifier
and then simply:
terminal-notifier -message "Hello, this is my message" -title "Message Title"

No, there are no dictionaries in php. The closest thing you have is an array. However, an array is different than a dictionary in that arrays have both an index and a key. Dictionaries only have keys and no index. What do I mean by that?
$array = array(
"foo" => "bar",
"bar" => "foo"
);
// as of PHP 5.4
$array = [
"foo" => "bar",
"bar" => "foo",
];
The following line is allowed with the above array but would give an error if it was a dictionary.
print $array[0]
Python has both arrays and dictionaries.
You can do it the DOM way as well:
var div = document.getElementById('cart_item');
while(div.firstChild){
div.removeChild(div.firstChild);
}
Best way to pass data to one Activity
to AnothetActivity
by using Intent
,
Check the code snipped
ActivityOne.java
Intent myIntent = new Intent(this, NewActivity.class);
myIntent.putExtra("key_name_one", "Your Data value here");
myIntent.putExtra("key_name_two", "Your data value here");
startActivity(myIntent)
On Your SecondActivity
SecondActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view);
Intent intent = getIntent();
String valueOne = intent.getStringExtra("key_name_one");
String valueTwo = intent.getStringExtra("key_name_two");
}
Requires Newtonsoft Json.Net
A little late, but I came up with this. It gives you just the keys and then you can use those on the dynamic:
public List<string> GetPropertyKeysForDynamic(dynamic dynamicToGetPropertiesFor)
{
JObject attributesAsJObject = dynamicToGetPropertiesFor;
Dictionary<string, object> values = attributesAsJObject.ToObject<Dictionary<string, object>>();
List<string> toReturn = new List<string>();
foreach (string key in values.Keys)
{
toReturn.Add(key);
}
return toReturn;
}
Then you simply foreach like this:
foreach(string propertyName in GetPropertyKeysForDynamic(dynamicToGetPropertiesFor))
{
dynamic/object/string propertyValue = dynamicToGetPropertiesFor[propertyName];
// And
dynamicToGetPropertiesFor[propertyName] = "Your Value"; // Or an object value
}
Choosing to get the value as a string or some other object, or do another dynamic and use the lookup again.
Resizing canvas using css is not a good idea. It should be done using Javascript. See the below function which does it
function setCanvas(){
var canvasNode = document.getElementById('xCanvas');
var pw = canvasNode.parentNode.clientWidth;
var ph = canvasNode.parentNode.clientHeight;
canvasNode.height = pw * 0.8 * (canvasNode.height/canvasNode.width);
canvasNode.width = pw * 0.8;
canvasNode.style.top = (ph-canvasNode.height)/2 + "px";
canvasNode.style.left = (pw-canvasNode.width)/2 + "px";
}

Maybe the 40 bytes fits into the pipe buffer, and the 40000 bytes doesn't?
Edit:
The sending process is sent a SIGPIPE signal when you try to write to a closed pipe. I don't know exactly when the signal is sent, or what effect the pipe buffer has on this. You may be able to recover by trapping the signal with the sigaction call.

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

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

I think the accepted answer is an awful way of handling this.
I don't know what the use case is, but please consider a protected method in the base class
@protected
void doSomething() {
}
and override it in the derived class.
When the event occurs, just call this method in the base class. The correct 'active' class will handle it then. The class itself can then check if it is not Paused()
.
Better yet, use an event bus like GreenRobot's, Square's, but that one is deprecated and suggests using RxJava

Question 1: Use .delegate
on the div to bind a click handler to the button.
Question 2: Use $(this).val()
or this.value
(the latter would be faster) inside of the click handler. this
will refer to the button.
$("#pg_menu_content").on('click', '#btn_a', function () {
alert($(this).val());
});
$div = $('<div data-role="fieldcontain"/>');
$("<input type='button' value='Dynamic Button' id='btn_a' />").appendTo($div.clone()).appendTo('#pg_menu_content');
I don't think that this is safe because e.g. the "=" character is used in raw base 64 and is also used in differentiating the parameters from the values in an HTTP GET.
(left, upper, right, lower) means two points,
with an 800x600 pixel image, the image's left upper point is (0, 0), the right lower point is (800, 600).
So, for cutting the image half:
from PIL import Image
img = Image.open("ImageName.jpg")
img_left_area = (0, 0, 400, 600)
img_right_area = (400, 0, 800, 600)
img_left = img.crop(img_left_area)
img_right = img.crop(img_right_area)
img_left.show()
img_right.show()
The Python Imaging Library uses a Cartesian pixel coordinate system, with (0,0) in the upper left corner. Note that the coordinates refer to the implied pixel corners; the centre of a pixel addressed as (0, 0) actually lies at (0.5, 0.5).
Coordinates are usually passed to the library as 2-tuples (x, y). Rectangles are represented as 4-tuples, with the upper left corner given first. For example, a rectangle covering all of an 800x600 pixel image is written as (0, 0, 800, 600).

As a one-liner function:
def is_leap_year(year):
"""Determine whether a year is a leap year."""
return year % 4 == 0 and (year % 100 != 0 or year % 400 == 0)
It's similar to the Mark's answer, but short circuits at the first test (note the parenthesis).
Alternatively, you can use the standard library's calendar.isleap
, which has exactly the same implementation:
from calendar import isleap
print(isleap(1900))
Taken from the ReactKonvaCore.d.ts file:
onClick?(evt: Konva.KonvaEventObject<MouseEvent>): void;
So, I'd say your event type is Konva.KonvaEventObject<MouseEvent>
According to your query
Select * from [User] U where U.DateCreated = '2014-02-07'
SQL Server is comparing exact date and time i.e (comparing 2014-02-07 12:30:47.220
with 2014-02-07 00:00:00.000
for equality). that's why result of comparison is false
Therefore, While comparing dates you need to consider time also. You can use
Select * from [User] U where U.DateCreated BETWEEN '2014-02-07' AND '2014-02-08'
.
The word check_
in the name means that if the command (the shell in this case that returns the exit status of the last command (yum
in this case)) returns non-zero status then it raises CalledProcessError
exception. It is by design. If the command that you want to run may return non-zero status on success then either catch this exception or don't use check_
methods. You could use subprocess.call
in your case because you are ignoring the captured output, e.g.:
import subprocess
rc = subprocess.call(['grep', 'pattern', 'file'],
stdout=subprocess.DEVNULL, stderr=subprocess.STDOUT)
if rc == 0: # found
...
elif rc == 1: # not found
...
elif rc > 1: # error
...
You don't need shell=True
to run the commands from your question.

UTF-8 is a variable-length encoding. In the case of UTF-8, this means that storing one code point requires one to four bytes. However, MySQL's encoding called "utf8" (alias of "utf8mb3") only stores a maximum of three bytes per code point.
So the character set "utf8"/"utf8mb3" cannot store all Unicode code points: it only supports the range 0x000 to 0xFFFF, which is called the "Basic Multilingual Plane". See also Comparison of Unicode encodings.
This is what (a previous version of the same page at) the MySQL documentation has to say about it:
The character set named utf8[/utf8mb3] uses a maximum of three bytes per character and contains only BMP characters. As of MySQL 5.5.3, the utf8mb4 character set uses a maximum of four bytes per character supports supplemental characters:
For a BMP character, utf8[/utf8mb3] and utf8mb4 have identical storage characteristics: same code values, same encoding, same length.
For a supplementary character, utf8[/utf8mb3] cannot store the character at all, while utf8mb4 requires four bytes to store it. Since utf8[/utf8mb3] cannot store the character at all, you do not have any supplementary characters in utf8[/utf8mb3] columns and you need not worry about converting characters or losing data when upgrading utf8[/utf8mb3] data from older versions of MySQL.
So if you want your column to support storing characters lying outside the BMP (and you usually want to), such as emoji, use "utf8mb4". See also What are the most common non-BMP Unicode characters in actual use?.
Trigger hardware accelerated rendering for the problematic element. I would advice to not do this on *, body or html tags for performance.
.problem{
-webkit-transform:translate3d(0,0,0);

vector::clear()
does not free memory allocated by the vector to store objects; it calls destructors for the objects it holds.
For example, if the vector uses an array as a backing store and currently contains 10 elements, then calling clear()
will call the destructor of each object in the array, but the backing array will not be deallocated, so there is still sizeof(T) * 10
bytes allocated to the vector (at least). size()
will be 0, but size()
returns the number of elements in the vector, not necessarily the size of the backing store.
As for your second question, anything you allocate with new
you must deallocate with delete
. You typically do not maintain a pointer to a vector for this reason. There is rarely (if ever) a good reason to do this and you prevent the vector from being cleaned up when it leaves scope. However, calling clear()
will still act the same way regardless of how it was allocated.
I had to do the following
/WebContent
from Deployment Assembly
and add /src/main/webapp
Server Runtimes
This got me working, in addition to @alanbartczak answer.
The case is like :
mysql connects will localhost when network is not up.
mysql cannot connect when network is up.
You can try the following steps to diagnose and resolve the issue (my guess is that some other service is blocking port on which mysql is hosted):
This should ideally resolve the issue you are facing.
"
is shown as \"
in the debugger, but the data is correct in the string, and you don't need to replace anything. Try to dump your string to a file and you will note that the string is correct.
This is how I did it in 2021
Let us say I have a csv sales.csv
which has the following data in it:
sales.csv:
Order Name,Price,Qty
oil,200,2
butter,180,10
and to add more rows I can load them in a data frame and append it to the csv like this:
import pandas
data = [
['matchstick', '60', '11'],
['cookies', '10', '120']
]
dataframe = pandas.DataFrame(data)
dataframe.to_csv("sales.csv", index=False, mode='a', header=False)
and the output will be:
Order Name,Price,Qty
oil,200,2
butter,180,10
matchstick,60,11
cookies,10,120
All above solutions are correct. But, when we are talking about a normal PHP application, they have to included in every page, that it requires. A way to solve this, is through .htaccess
at root folder.
Just to hide the errors. [Put one of the followling lines in the file]
php_flag display_errors off
Or
php_value display_errors 0
Next, to set the error reporting
php_value error_reporting 30719
If you are wondering how the value 30719
came, E_ALL (32767), E_STRICT (2048) are actually constant that hold numeric value and (32767 - 2048 = 30719
)
Depending on your context; this will allow you to update state given the mouseEnter function. Either way, by setting a state value to either true:false you can update that state value given any function by setting it to the opposing value with !this.state.variable
state = {
hover: false
}
onMouseEnter = () => {
this.setState({
hover: !this.state.hover
});
};
LayoutInflator
do?When I first started Android programming, I was really confused by LayoutInflater
and findViewById
. Sometimes we used one and sometimes the other.
LayoutInflater
is used to create a new View
(or Layout
) object from one of your xml layouts.findViewById
just gives you a reference to a view than has already been created. You might think that you haven't created any views yet, but whenever you call setContentView
in onCreate
, the activity's layout along with its subviews gets inflated (created) behind the scenes.So if the view already exists, then use findViewById
. If not, then create it with a LayoutInflater
.
Here is a mini project I made that shows both LayoutInflater
and findViewById
in action. With no special code, the layout looks like this.
The blue square is a custom layout inserted into the main layout with include
(see here for more). It was inflated automatically because it is part of the content view. As you can see, there is nothing special about the code.
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Now let's inflate (create) another copy of our custom layout and add it in.
LayoutInflater inflater = getLayoutInflater();
View myLayout = inflater.inflate(R.layout.my_layout, mainLayout, false);
To inflate the new view layout, all I did was tell the inflater the name of my xml file (my_layout
), the parent layout that I want to add it to (mainLayout
), and that I don't actually want to add it yet (false
). (I could also set the parent to null
, but then the layout parameters of my custom layout's root view would be ignored.)
Here it is again in context.
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// inflate the main layout for the activity
setContentView(R.layout.activity_main);
// get a reference to the already created main layout
LinearLayout mainLayout = (LinearLayout) findViewById(R.id.activity_main_layout);
// inflate (create) another copy of our custom layout
LayoutInflater inflater = getLayoutInflater();
View myLayout = inflater.inflate(R.layout.my_layout, mainLayout, false);
// make changes to our custom layout and its subviews
myLayout.setBackgroundColor(ContextCompat.getColor(this, R.color.colorAccent));
TextView textView = (TextView) myLayout.findViewById(R.id.textView);
textView.setText("New Layout");
// add our custom layout to the main layout
mainLayout.addView(myLayout);
}
}
Notice how findViewById
is used only after a layout has already been inflated.
Here is the xml for the example above.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/activity_main_layout"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp">
<!-- Here is the inserted layout -->
<include layout="@layout/my_layout"/>
</LinearLayout>
my_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="100dp"
android:layout_height="100dp"
android:background="@color/colorPrimary">
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:padding="5dp"
android:textColor="@android:color/white"
android:text="My Layout"/>
</RelativeLayout>
RecyclerView
. (See these RecyclerView
examples for a list or a grid.) You have to inflate a new layout for every single visible item in the list or grid.This is how I used this is as an example:
CAST(vAvgMaterialUnitCost.`avgUnitCost` AS DECIMAL(11,2)) * woMaterials.`qtyUsed` AS materialCost
Set the width of the <td>
s to 50px
and then add your <td>
+ another fake <td>
table tr td:empty {_x000D_
width: 50px;_x000D_
}_x000D_
_x000D_
table tr td {_x000D_
padding-top: 10px;_x000D_
padding-bottom: 10px;_x000D_
}
_x000D_
<table>_x000D_
<tr>_x000D_
<td>First Column</td>_x000D_
<td></td>_x000D_
<td>Second Column</td>_x000D_
<td></td>_x000D_
<td>Third Column</td>_x000D_
</tr>_x000D_
</table>
_x000D_
Code Explained:
The first CSS rule checks for empty td's and give them a width of 50px then the second rule give the padding of top and bottom to all the td's.
On Linux, Unix, Git Bash, or Cygwin, try:
rm -f .git/index.lock
On Windows Command Prompt, try:
del .git\index.lock
For Windows:
From a PowerShell console opened as administrator, try
rm -Force ./.git/index.lock
If that does not work, you must kill all git.exe processes
taskkill /F /IM git.exe
SUCCESS: The process "git.exe" with PID 20448 has been terminated.
SUCCESS: The process "git.exe" with PID 11312 has been terminated.
SUCCESS: The process "git.exe" with PID 23868 has been terminated.
SUCCESS: The process "git.exe" with PID 27496 has been terminated.
SUCCESS: The process "git.exe" with PID 33480 has been terminated.
SUCCESS: The process "git.exe" with PID 28036 has been terminated. \
rm -Force ./.git/index.lock
You could use a std::stringstream. You can stream anything into it:
std::stringstream stream;
stream << 5.7;
stream << foo.bar;
std::string s = stream.str();
That should be a quite general approach. (Works only for C++, but you asked the question for this language too.)
