Question still relevant as of Android Studio 3.5.2 for Windows.
In my specific use case, I was trying to add Gander (https://github.com/Ashok-Varma/Gander) to my list of dependencies when I keep getting this particular headache.
It turns out that I have yet to get JCenter Certificate approved in my cacerts
file. I'm going through a company firewall and i had to do this with dependencies that I attempt to import. Thus, to do so:
Ensure that your Android Studio does not need to go through any proxy.
Export the certificate where you get your dependency (usually just JCenter)
Add the certificate to your cacerts
file:
keytool -import -alias [your-certificate-name] -keystore 'C:\Program Files\Java\jdk[version]\jre\lib\security\cacerts' -file [absolute\path\to\your\certificate].cer
Restart Android Studio
Try syncing again.

You could use dplyr
:
df %>% group_by("Amount") %>% slice(which.min(x))

You'll get this error as well if you are verifying that an extension method of an interface is called.
For example if you are mocking:
var mockValidator = new Mock<IValidator<Foo>>();
mockValidator
.Verify(validator => validator.ValidateAndThrow(foo, null));
You will get the same exception because .ValidateAndThrow()
is an extension on the IValidator<T>
interface.
public static void ValidateAndThrow<T>(this IValidator<T> validator, T instance, string ruleSet = null)...
You can use Hudson Groovy builder to do this.

I would like to add to Justin and Power's answer that -
repartition
will ignore existing partitions and create new ones. So you can use it to fix data skew. You can mention partition keys to define the distribution. Data skew is one of the biggest problems in the 'big data' problem space.
coalesce
will work with existing partitions and shuffle a subset of them. It can't fix the data skew as much as repartition
does. Therefore even if it is less expensive it might not be the thing you need.
Here is the Angular version of LightBox. Just Awesome :)
Note : I have put this answer hence No Js library has been mentioned under the Tags.
<ul ng-controller="GalleryCtrl">

preds_test[0] is of shape (128,128,1) Lets check its data type using isinstance() function isinstance takes 2 arguments. 1st argument is data 2nd argument is data type isinstance(preds_test[0], np.ndarray) gives Output as True. It means preds_test[0] is an array.
May be sometimes upgrading to a superuser might not be a good option. So apart from super user there are lot of other options which you can use. Open your terminal and type the following:
$ sudo su - postgres
[sudo] password for user: (type your password here)
$ psql
postgres@user:~$ psql
psql (10.5 (Ubuntu 10.5-1.pgdg18.04+1))
Type "help" for help.
postgres=# ALTER USER my_user WITH option
Also listing the list of options
SUPERUSER | NOSUPERUSER | CREATEDB | NOCREATEDB | CREATEROLE | NOCREATEROLE |
CREATEUSER | NOCREATEUSER | INHERIT | NOINHERIT | LOGIN | NOLOGIN | REPLICATION|
NOREPLICATION | BYPASSRLS | NOBYPASSRLS | CONNECTION LIMIT connlimit |
[ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password' | VALID UNTIL 'timestamp'
So in command line it will look like
postgres=# ALTER USER my_user WITH LOGIN
OR use an encrypted password.
postgres=# ALTER USER my_user WITH ENCRYPTED PASSWORD '5d41402abc4b2a76b9719d911017c592';
OR revoke permissions after a specific time.
postgres=# ALTER USER my_user WITH VALID UNTIL '2019-12-29 19:09:00';
Try:
System.IO.Directory.Delete(path,true)
This will recursively delete all files and folders underneath "path" assuming you have the permissions to do so.
A quick and easy way for Mac OS X 10.8 (Mountain Lion), 10.9 (Mavericks), 10.10 (Yosemite), and 10.11 (El Capitan):
I assume you have XCode, its command line tools, Python, and MySQL installed.
Install PIP:
sudo easy_install pip
Edit ~/.profile: (Might not be necessary in Mac OS X 10.10)
nano ~/.profile
Copy and paste the following two line
export PATH=/usr/local/mysql/bin:$PATH
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
Save and exit. Afterwords execute the following command:
source ~/.profile
Install MySQLdb
sudo pip install MySQL-python
To test if everything works fine just try
python -c "import MySQLdb"
It worked like a charm for me. I hope it helps.
If you encounter an error regarding a missing library: Library not loaded: libmysqlclient.18.dylib then you have to symlink it to /usr/lib
like so:
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
CREATE TABLE `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`dateCreated` datetime DEFAULT CURRENT_TIMESTAMP,
`dateUpdated` datetime DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
UNIQUE KEY `mobile_UNIQUE` (`mobile`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
The answer above with spark-csv is correct but there is an issue - the library creates several files based on the data frame partitioning. And this is not what we usually need. So, you can combine all partitions to one:
df.coalesce(1).
write.
format("com.databricks.spark.csv").
option("header", "true").
save("myfile.csv")
and rename the output of the lib (name "part-00000") to a desire filename.

SEARCH
does not return 0
if there is no match, it returns #VALUE!
. So you have to wrap calls to SEARCH
with IFERROR
.
For example...
=IF(IFERROR(SEARCH("cat", A1), 0), "cat", "none")
or
=IF(IFERROR(SEARCH("cat",A1),0),"cat",IF(IFERROR(SEARCH("22",A1),0),"22","none"))
Here, IFERROR
returns the value from SEARCH
when it works; the given value of 0
otherwise.
I think i am understanding your question. This filters things that are in the column labels or the row labels. The last 2 sections of the code is what you want but im pasting everything so that you can see exactly how It runs start to finish with everything thats defined etc. I definitely took some of this code from other sites fyi.
Near the end of the code, the "WardClinic_Category" is a column of my data and in the column label of the pivot table. Same for the IVUDDCIndicator (its a column in my data but in the row label of the pivot table).
Hope this helps others...i found it very difficult to find code that did this the "proper way" rather than using code similar to the macro recorder.

X-Powered-By
is a custom header in IIS. Since IIS 7, you can remove it by adding the following to your web.config
:
<system.webServer>
<httpProtocol>
<customHeaders>
<remove name="X-Powered-By" />
</customHeaders>
</httpProtocol>
</system.webServer>
This header can also be modified to your needs, for more information refer to http://www.iis.net/ConfigReference/system.webServer/httpProtocol/customHeaders
Add this to web.config
to get rid of the X-AspNet-Version
header:
<system.web>
<httpRuntime enableVersionHeader="false" />
</system.web>
Finally, to remove X-AspNetMvc-Version
, edit Global.asax.cs
and add the following in the Application_Start
event:
protected void Application_Start()
{
MvcHandler.DisableMvcResponseHeader = true;
}
You can also modify headers at runtime via the Application_PreSendRequestHeaders
event in Global.asax.cs
. This is useful if your header values are dynamic:
protected void Application_PreSendRequestHeaders(object source, EventArgs e)
{
Response.Headers.Remove("foo");
Response.Headers.Add("bar", "quux");
}
With pure Javascript, you'd have to cycle through each option, and check the value of it individually.
// Get all options within <select id='foo'>...</select>
var op = document.getElementById("foo").getElementsByTagName("option");
for (var i = 0; i < op.length; i++) {
// lowercase comparison for case-insensitivity
(op[i].value.toLowerCase() == "stackoverflow")
? op[i].disabled = true
: op[i].disabled = false ;
}
Without enabling non-targeted elements:
// Get all options within <select id='foo'>...</select>
var op = document.getElementById("foo").getElementsByTagName("option");
for (var i = 0; i < op.length; i++) {
// lowercase comparison for case-insensitivity
if (op[i].value.toLowerCase() == "stackoverflow") {
op[i].disabled = true;
}
}
With jQuery you can do this with a single line:
$("option[value='stackoverflow']")
.attr("disabled", "disabled")
.siblings().removeAttr("disabled");
Without enabling non-targeted elements:
$("option[value='stackoverflow']").attr("disabled", "disabled");
? Note that this is not case insensitive. "StackOverflow" will not equal "stackoverflow". To get a case-insensitive match, you'd have to cycle through each, converting the value to a lower case, and then check against that:
$("option").each(function(){
if ($(this).val().toLowerCase() == "stackoverflow") {
$(this).attr("disabled", "disabled").siblings().removeAttr("disabled");
}
});
Without enabling non-targeted elements:
$("option").each(function(){
if ($(this).val().toLowerCase() == "stackoverflow") {
$(this).attr("disabled", "disabled");
}
});
I was getting this error with Laravel Sanctum. I fixed it by adding \Illuminate\Session\Middleware\StartSession::class,
to the api
middleware group in Kernel.php, but I later figured out this "worked" because my authentication routes were added in api.php
instead of web.php
, so Laravel was using the wrong auth guard.
I moved these routes here into web.php
and then they started working properly with the AuthenticatesUsers.php
trait:
Route::group(['middleware' => ['guest', 'throttle:10,5']], function () {
Route::post('register', 'Auth\RegisterController@register')->name('register');
Route::post('login', 'Auth\LoginController@login')->name('login');
Route::post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
Route::post('password/reset', 'Auth\ResetPasswordController@reset');
Route::post('email/verify/{user}', 'Auth\VerificationController@verify')->name('verification.verify');
Route::post('email/resend', 'Auth\VerificationController@resend');
Route::post('oauth/{driver}', 'Auth\OAuthController@redirectToProvider')->name('oauth.redirect');
Route::get('oauth/{driver}/callback', 'Auth\OAuthController@handleProviderCallback')->name('oauth.callback');
});
Route::post('logout', 'Auth\LoginController@logout')->name('logout');
I figured out the problem after I got another weird error about RequestGuard::logout()
does not exist.
It made me realize that my custom auth routes are calling methods from the AuthenticatesUsers trait, but I wasn't using Auth::routes()
to accomplish it. Then I realized Laravel uses the web guard by default and that means routes should be in routes/web.php
.
This is what my settings look like now with Sanctum and a decoupled Vue SPA app:
Kernel.php
protected $middlewareGroups = [
'web' => [
\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
// \Illuminate\Session\Middleware\AuthenticateSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\VerifyCsrfToken::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
],
'api' => [
EnsureFrontendRequestsAreStateful::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
'throttle:60,1',
],
];
Note: With Laravel Sanctum and same-domain Vue SPA, you use httpOnly cookies for session cookie, and remember me cookie, and unsecure cookie for CSRF, so you use the
web
guard for auth, and every other protected, JSON-returning route should useauth:sanctum
middleware.
config/auth.php
'defaults' => [
'guard' => 'web',
'passwords' => 'users',
],
...
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'token',
'provider' => 'users',
'hash' => false,
],
],
Then you can have unit tests such as this, where critically, Auth::check()
, Auth::user()
, and Auth::logout()
work as expected with minimal config and maximal usage of AuthenticatesUsers
and RegistersUsers
traits.
Here are a couple of my login unit tests:
TestCase.php
/**
* Creates and/or returns the designated regular user for unit testing
*
* @return \App\User
*/
public function user() : User
{
$user = User::query()->firstWhere('email', '[email protected]');
if ($user) {
return $user;
}
// User::generate() is just a wrapper around User::create()
$user = User::generate('Test User', '[email protected]', self::AUTH_PASSWORD);
return $user;
}
/**
* Resets AuthManager state by logging out the user from all auth guards.
* This is used between unit tests to wipe cached auth state.
*
* @param array $guards
* @return void
*/
protected function resetAuth(array $guards = null) : void
{
$guards = $guards ?: array_keys(config('auth.guards'));
foreach ($guards as $guard) {
$guard = $this->app['auth']->guard($guard);
if ($guard instanceof SessionGuard) {
$guard->logout();
}
}
$protectedProperty = new \ReflectionProperty($this->app['auth'], 'guards');
$protectedProperty->setAccessible(true);
$protectedProperty->setValue($this->app['auth'], []);
}
LoginTest.php
protected $auth_guard = 'web';
/** @test */
public function it_can_login()
{
$user = $this->user();
$this->postJson(route('login'), ['email' => $user->email, 'password' => TestCase::AUTH_PASSWORD])
->assertStatus(200)
->assertJsonStructure([
'user' => [
...expectedUserFields,
],
]);
$this->assertEquals(Auth::check(), true);
$this->assertEquals(Auth::user()->email, $user->email);
$this->assertAuthenticated($this->auth_guard);
$this->assertAuthenticatedAs($user, $this->auth_guard);
$this->resetAuth();
}
/** @test */
public function it_can_logout()
{
$this->actingAs($this->user())
->postJson(route('logout'))
->assertStatus(204);
$this->assertGuest($this->auth_guard);
$this->resetAuth();
}
I overrided the registered
and authenticated
methods in the Laravel auth traits so that they return the user object instead of just the 204 OPTIONS:
public function authenticated(Request $request, User $user)
{
return response()->json([
'user' => $user,
]);
}
protected function registered(Request $request, User $user)
{
return response()->json([
'user' => $user,
]);
}
Look at the vendor code for the auth traits. You can use them untouched, plus those two above methods.
Here is my Vue SPA's Vuex actions for login:
async login({ commit }, credentials) {
try {
const { data } = await axios.post(route('login'), {
...credentials,
remember: credentials.remember || undefined,
});
commit(FETCH_USER_SUCCESS, { user: data.user });
commit(LOGIN);
return commit(CLEAR_INTENDED_URL);
} catch (err) {
commit(LOGOUT);
throw new Error(`auth/login# Problem logging user in: ${err}.`);
}
},
async logout({ commit }) {
try {
await axios.post(route('logout'));
return commit(LOGOUT);
} catch (err) {
commit(LOGOUT);
throw new Error(`auth/logout# Problem logging user out: ${err}.`);
}
},
It took me over a week to get Laravel Sanctum + same-domain Vue SPA + auth unit tests all working up to my standard, so hopefully my answer here can help save others time in the future.
October 2017
I would like to add another Bootstrap 4 solution. One that worked for me.
The CSS "Order" property, combined with a media query, can be used to re-order columns when they get stacked in smaller screens.
Something like this:
@media only screen and (max-width: 768px) {
#first {
order: 2;
}
#second {
order: 4;
}
#third {
order: 1;
}
#fourth {
order: 3;
}
}
CodePen Link: https://codepen.io/preston206/pen/EwrXqm
Adjust the screen size and you'll see the columns get stacked in a different order.
I'll tie this in with the original poster's question. With CSS, the navbar, sidebar, and content can be targeted and then order properties applied within a media query.
The bootstrap css used in the jsfiddle link, dont have the css for col-xs-offset-*, thats why the css are not been applied. Refer the latest bootstrap css.
Dont define varibale in header file , do declaration in header file(good practice ) .. in your case it is working because multiple weak symbols .. Read about weak and strong symbol ....link :http://csapp.cs.cmu.edu/public/ch7-preview.pdf
This type of code create problem while porting.
As of Laravel 5.7 you can pass an array of options to Auth::routes()
. You can then disable the register routes with:
Auth::routes(['register' => false]);
You can see how this works from the source code: src/Illuminate/Routing/Router.php.
apt-get install ruby-dev
worked for me.
Consider the below situation
public class Person{
public String Name{get; set;}
public String Email {get; set;}
public virtual Employer employer {get; set;}
}
public List<EF.Person> GetPerson(){
using(EF.DbEntities db = new EF.DbEntities()){
return db.Person.ToList();
}
}
Now after this method is called, you cannot lazy load the Employer
entity anymore. Why? because the db
object is disposed. So you have to do Person.Include(x=> x.employer)
to force that to be loaded.
You really don't need jQuery for this.
var myarr = ["I", "like", "turtles"];
var arraycontainsturtles = (myarr.indexOf("turtles") > -1);
Hint: indexOf returns a number, representing the position where the specified searchvalue occurs for the first time, or -1 if it never occurs
or
function arrayContains(needle, arrhaystack)
{
return (arrhaystack.indexOf(needle) > -1);
}
It's worth noting that array.indexOf(..)
is not supported in IE < 9, but jQuery's indexOf(...)
function will work even for those older versions.
Another option is to add another tag with flex: auto
style in between your tags that you want to fill in the remaining space.
https://jsfiddle.net/tsey5qu4/
The HTML:
<div class="parent">
<div class="left">Left</div>
<div class="fill-remaining-space"></div>
<div class="right">Right</div>
</div>
The CSS:
.fill-remaining-space {
flex: auto;
}
This is equivalent to flex: 1 1 auto, which absorbs any extra space along the main axis.
Finally after comparing all solution, I think starting from build.gradle
file can be convenient.
Gradle distribution has samples
folder with a lot of examples, and there is gradle init --type basic
comand see Chapter 47. Build Init Plugin. But they all needs some editing.
You can use template below as well, then run gradle initSourceFolders eclipse
/*
* Nodeclipse/Enide build.gradle template for basic Java project
* https://github.com/Nodeclipse/nodeclipse-1/blob/master/org.nodeclipse.enide.editors.gradle/docs/java/basic/build.gradle
* Initially asked on
* http://stackoverflow.com/questions/14017364/how-to-create-java-gradle-project
* Usage
* 1. create folder (or general Eclipse project) and put this file inside
* 2. run `gradle initSourceFolders eclipse` or `gradle initSourceFolders idea`
* @author Paul Verest;
* based on `gradle init --type basic`, that does not create source folders
*/
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
task initSourceFolders { // add << before { to prevent executing during configuration phase
sourceSets*.java.srcDirs*.each { it.mkdirs() }
sourceSets*.resources.srcDirs*.each { it.mkdirs() }
}
task wrapper(type: Wrapper) {
gradleVersion = '1.11'
}
// In this section you declare where to find the dependencies of your project
repositories {
// Use Maven Central for resolving your dependencies.
// You can declare any Maven/Ivy/file repository here.
mavenCentral()
}
// In this section you declare the dependencies for your production and test code
dependencies {
//compile fileTree(dir: 'libs', include: '*.jar')
// The production code uses the SLF4J logging API at compile time
//compile 'org.slf4j:slf4j-api:1.7.5'
// Declare the dependency for your favourite test framework you want to use in your tests.
// TestNG is also supported by the Gradle Test task. Just change the
// testCompile dependency to testCompile 'org.testng:testng:6.8.1' and add
// 'test.useTestNG()' to your build script.
testCompile "junit:junit:4.11"
}
The result is like below.
That can be used without any Gradle plugin for Eclipse,
or with (Enide) Gradle for Eclipse, Jetty, Android alternative to Gradle Integration for Eclipse
Based on your application type/size/load/no. of users ..etc - u can keep following as your production properties
spring.datasource.tomcat.initial-size=50
spring.datasource.tomcat.max-wait=20000
spring.datasource.tomcat.max-active=300
spring.datasource.tomcat.max-idle=150

spring.datasource.tomcat.default-auto-commit=true
$sql = "SELECT * FROM table";
$result = $conn->query($sql);
if (!$result) {
trigger_error('Invalid query: ' . $conn->error);
}
check the error with mysqli_error() function
probably your query has some faults.
SQL Server was not configured to allow mixed authentication.
Here are steps to fix:
Select the SQL Server and Windows Authentication mode radio button, and click OK.
Right-click on the SQL Server instance, select Restart (alternatively, open up Services and restart the SQL Server service).
This is also incredibly helpful for IBM Connections users, my wizards were not able to connect until I fxed this setting.
You can't write binary literals like 00101011
in Java so you can write it in hexadecimal instead:
byte x = 0x2b;
To calculate the result of x >> 2
you can then just write exactly that and print the result.
System.out.println(x >> 2);
The values are determined by the bit of the image. 8 bit 0 to 255
16 bit...some ridiculous number..0 to 65,000 approx.
32 bit are 0 to 1
I use .004 with 32 bit images...this gives 1.02 as a result when multiplied by 255
I know this is old but I didn't see anyone mention extending the String prototype
.
String.prototype.replaceAll = function(search, replace){
if(!search || !replace){return this;} //if search entry or replace entry empty return the string
return this.replace(new RegExp('[' + search + ']', 'g'), replace); //global RegEx search for all instances ("g") of your search entry and replace them all.
};
I always write a default method "findByIdOrError" in widely used CrudRepository repos/interfaces.
@Repository
public interface RequestRepository extends CrudRepository<Request, Integer> {
default Request findByIdOrError(Integer id) {
return findById(id).orElseThrow(EntityNotFoundException::new);
}
}
You can open any folder, so if your projects are in the same tree, just open the folder beneath them.
Otherwise you can open 2 instances of Code as another option

}
func encodeWithCoder(aCoder: NSCoder) {
aCoder.encodeObject(self.name, forKey: "name")
aCoder.encodeObject(self.url, forKey: "url")
aCoder.encodeObject(self.desc, forKey: "desc")
}
}
2) To save data use following function:
func saveData()
{
let data = NSKeyedArchiver.archivedDataWithRootObject(custom)
let defaults = NSUserDefaults.standardUserDefaults()
defaults.setObject(data, forKey:"customArray" )
}
3) To retrieve:
if let data = NSUserDefaults.standardUserDefaults().objectForKey("customArray") as? NSData
{
custom = NSKeyedUnarchiver.unarchiveObjectWithData(data) as! [customData]
}
Note: Here I am saving and retrieving an array of the custom class objects.
If you use the gradle-android-plugin to build your app, then you can use
BuildConfig.APPLICATION_ID
to retrieve the package name from any scope, incl. a static one.
Easier still: return a pointer to a string that's been malloc'd with strdup.
#include <ncurses.h>
char * getStr(int length)
{
char word[length];
for (int i = 0; i < length; i++)
{
word[i] = getch();
}
word[i] = '\0';
return strdup(&word[0]);
}
int main()
{
char wordd[10];
initscr();
*wordd = getStr(10);
printw("The string is:\n");
printw("%s\n",*wordd);
getch();
endwin();
return 0;
}
Turns out string starting with a newline (or anything other than "<") is not considered HTML string in jQuery 1.9

Set the check box after loading the modal window. I think you are setting the check box before loading the page.
$('#fModal').modal('show');
$("#estado_cat").attr("checked","checked");
Synchronous solution :
void DisplayProcessStatus(Process process)
{
process.Refresh(); // Important
if(process.HasExited)
{
Console.WriteLine("Exited.");
}
else
{
Console.WriteLine("Running.");
}
}
Asynchronous solution:
void RegisterProcessExit(Process process)
{
// NOTE there will be a race condition with the caller here
// how to fix it is left as an exercise
process.Exited += process_Exited;
}
static void process_Exited(object sender, EventArgs e)
{
Console.WriteLine("Process has exited.");
}
string = 'http://www.domain.com/?s=some&two=20'
cut_string = string.split('&')
new_string = cut_string[0]
print(new_string)
I think what you originally meant to do was to make an array only of characters, not of pointers:
char options[2][100];
options[0][0]='t';
options[0][1]='e';
options[0][2]='s';
options[0][3]='t';
options[0][4]='1';
options[0][5]='\0'; /* NUL termination of C string */
/* A standard C library function which copies strings. */
strcpy(options[1], "test2");
The code above shows two distinct methods of setting the character values in memory you have set aside to contain characters.
[a-zA-Z0-9] will only match ASCII characters, it won't match
String target = new String("A" + "\u00ea" + "\u00f1" +
"\u00fc" + "C");
If you also want to match unicode characters:
String pat = "^[\\p{L}0-9]*$";
<a href="https://www." style="color: inherit;"target="_blank">
For CSS inline style, this worked best for me.
I am just sharing my experience here, I used angular.copy() for comparing two objects properties. I was working on a number of inputs without form element, I was wondering how to compare two objects properties and based on result I have to enable and disable the save button. So I used as below.
I assigned an original server object user values to my dummy object to say userCopy and used watch to check changes to the user object.
My server API which gets me data from the server:
var req = {
method: 'GET',
url: 'user/profile/' + id,
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}
$http(req).success(function(data) {
$scope.user = data;
$scope.userCopy = angular.copy($scope.user);
$scope.btnSts=true;
}).error(function(data) {
$ionicLoading.hide();
});
//initially my save button is disabled because objects are same, once something
//changes I am activating save button
$scope.btnSts = true;
$scope.$watch('user', function(newVal, oldVal) {
console.log($scope.userCopy.name);
if ($scope.userCopy.name !== $scope.user.name || $scope.userCopy.email !== $scope.user.email) {
console.log('Changed');
$scope.btnSts = false;
} else {
console.log('Unchanged');
$scope.btnSts = true;
}
}, true);
I am not sure but comparing two objects was really headache for me always but with angular.copy() it went smoothly.
As mentioned, ini4j can be used to achieve this. Let me show one other example.
If we have an INI file like this:
[header]
key = value
The following should display value
to STDOUT:
Ini ini = new Ini(new File("/path/to/file"));
System.out.println(ini.get("header", "key"));
Check the tutorials for more examples.
stdio is part of the standard C library which, by default, gcc will link against.
The math function implementations are in a separate libm file that is not linked to by default so you have to specify it -lm. By the way, there is no relation between those header files and library files.
Try the following query:
collection.update(
{ _id: id },
{ $pull: { 'contact.phone': { number: '+1786543589455' } } }
);
It will find document with the given _id
and remove the phone +1786543589455
from its contact.phone
array.
You can use $unset
to unset the value in the array (set it to null
), but not to remove it completely.
The current way to do this is by using the "Add Service Reference" command. If you specify "TestUploaderWebService
" as the service reference name, that will generate the type TestUploaderWebService.Service1
. That class will have a method named GetFileListOnWebServer
, which will return an array of strings (you can change that to be a list of strings if you like). You would use it like this:
string[] files = null;
TestUploaderWebService.Service1 proxy = null;
bool success = false;
try
{
proxy = new TestUploaderWebService.Service1();
files = proxy.GetFileListOnWebServer();
proxy.Close();
success = true;
}
finally
{
if (!success)
{
proxy.Abort();
}
}
P.S. Tell your instructor to look at "Microsoft: ASMX Web Services are a “Legacy Technology”", and ask why he's teaching out of date technology.
If you want to convert a single VARBINARY
value into VARCHAR
(STRING
) you can do by declaring a variable like this:
DECLARE @var VARBINARY(MAX)
SET @var = 0x21232F297A57A5A743894A0E4A801FC3
SELECT CAST(@var AS VARCHAR(MAX))
If you are trying to select from table column then you can do like this:
SELECT CAST(myBinaryCol AS VARCHAR(MAX))
FROM myTable
git log --oneline | grep PATTERN
Internally, getters and setters are just methods. When C# compiles, it generates methods for your getters and setters like this, for example:
public int get_MyProperty() { ... }
public void set_MyProperty(int value) { ... }
C# allows you to declare these methods using a short-hand syntax. The line below will be compiled into the methods above when you build your application.
public int MyProperty { get; set; }
or
private int myProperty;
public int MyProperty
{
get { return myProperty; }
set { myProperty = value; } // value is an implicit parameter containing the value being assigned to the property.
}
If you don't need to handle raster files and PDF/PS/EPS through the same tool, don't loosen ImageMagick's security.
Instead, keep your defense in depth for your web applications intact, check that your Ghostscript has been patched for all known -dSAFER
vulnerabilities and then invoke it directly.
gs -dSAFER -r300 -sDEVICE=png16m -o document-%03d.png document.pdf
-dSAFER
opts you out of the legacy-compatibility "run Postscript will full permission to interact with the outside world as a turing-complete programming language" mode.-r300
sets the desired DPI to 300 (the default is 72)-sDEVICE
specifies the output format (See the Devices section of the manual for other choices.)-o
is a shorthand for -dBATCH -dNOPAUSE -sOutputFile=
If you're rendering EPS files, add -dEPSCrop
so it won't pad your output to page size and use -sDEVICE=pngalpha
to get transparent backgrounds.

Short version: Yes it is faster, with less code!
String concatenation does a lot of work without knowing if it is needed or not (the traditional "is debugging enabled" test known from log4j), and should be avoided if possible, as the {} allows delaying the toString() call and string construction to after it has been decided if the event needs capturing or not. By having the logger format a single string the code becomes cleaner in my opinion.
You can provide any number of arguments. Note that if you use an old version of sljf4j and you have more than two arguments to {}
, you must use the new Object[]{a,b,c,d}
syntax to pass an array instead. See e.g. http://slf4j.org/apidocs/org/slf4j/Logger.html#debug(java.lang.String, java.lang.Object[]).
Regarding the speed: Ceki posted a benchmark a while back on one of the lists.
I encountered this error when the JDK that I compiled the app under was different from the tomcat JVM. I verified that the Tomcat manager was running jvm 1.6.0 but the app was compiled under java 1.7.0.
After upgrading Java and changing JAVA_HOME in our startup script (/etc/init.d/tomcat) the error went away.
You should probably take a look at the open source Reflections library. With it you can easily achieve what you want.
First, setup the reflections index (it's a bit messy since searching for all classes is disabled by default):
List<ClassLoader> classLoadersList = new LinkedList<ClassLoader>();
classLoadersList.add(ClasspathHelper.contextClassLoader());
classLoadersList.add(ClasspathHelper.staticClassLoader());
Reflections reflections = new Reflections(new ConfigurationBuilder()
.setScanners(new SubTypesScanner(false /* don't exclude Object.class */), new ResourcesScanner())
.setUrls(ClasspathHelper.forClassLoader(classLoadersList.toArray(new ClassLoader[0])))
.filterInputsBy(new FilterBuilder().include(FilterBuilder.prefix("org.your.package"))));
Then you can query for all objects in a given package:
Set<Class<?>> classes = reflections.getSubTypesOf(Object.class);
That is not HTML, but PHP. It is called the HEREDOC string method, and is an alternative to using quotes for writing multiline strings.
The HTML in your example will be:
<tr>
<td>TEST</td>
</tr>
Read the PHP documentation that explains it.
You can wrap input stream with PushbackInputStream. PushbackInputStream allows to unread ("write back") bytes which were already read, so you can do like this:
public class StreamTest {
public static void main(String[] args) throws IOException {
byte[] bytes = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
InputStream originalStream = new ByteArrayInputStream(bytes);
byte[] readBytes = getBytes(originalStream, 3);
printBytes(readBytes); // prints: 1 2 3
readBytes = getBytes(originalStream, 3);
printBytes(readBytes); // prints: 4 5 6
// now let's wrap it with PushBackInputStream
originalStream = new ByteArrayInputStream(bytes);
InputStream wrappedStream = new PushbackInputStream(originalStream, 10); // 10 means that maximnum 10 characters can be "written back" to the stream
readBytes = getBytes(wrappedStream, 3);
printBytes(readBytes); // prints 1 2 3
((PushbackInputStream) wrappedStream).unread(readBytes, 0, readBytes.length);
readBytes = getBytes(wrappedStream, 3);
printBytes(readBytes); // prints 1 2 3
}
private static byte[] getBytes(InputStream is, int howManyBytes) throws IOException {
System.out.print("Reading stream: ");
byte[] buf = new byte[howManyBytes];
int next = 0;
for (int i = 0; i < howManyBytes; i++) {
next = is.read();
if (next > 0) {
buf[i] = (byte) next;
}
}
return buf;
}
private static void printBytes(byte[] buffer) throws IOException {
System.out.print("Reading stream: ");
for (int i = 0; i < buffer.length; i++) {
System.out.print(buffer[i] + " ");
}
System.out.println();
}
}
Please note that PushbackInputStream stores internal buffer of bytes so it really creates a buffer in memory which holds bytes "written back".
Knowing this approach we can go further and combine it with FilterInputStream. FilterInputStream stores original input stream as a delegate. This allows to create new class definition which allows to "unread" original data automatically. The definition of this class is following:
public class TryReadInputStream extends FilterInputStream {
private final int maxPushbackBufferSize;
/**
* Creates a <code>FilterInputStream</code>
* by assigning the argument <code>in</code>
* to the field <code>this.in</code> so as
* to remember it for later use.
*
* @param in the underlying input stream, or <code>null</code> if
* this instance is to be created without an underlying stream.
*/
public TryReadInputStream(InputStream in, int maxPushbackBufferSize) {
super(new PushbackInputStream(in, maxPushbackBufferSize));
this.maxPushbackBufferSize = maxPushbackBufferSize;
}
/**
* Reads from input stream the <code>length</code> of bytes to given buffer. The read bytes are still avilable
* in the stream
*
* @param buffer the destination buffer to which read the data
* @param offset the start offset in the destination <code>buffer</code>
* @aram length how many bytes to read from the stream to buff. Length needs to be less than
* <code>maxPushbackBufferSize</code> or IOException will be thrown
*
* @return number of bytes read
* @throws java.io.IOException in case length is
*/
public int tryRead(byte[] buffer, int offset, int length) throws IOException {
validateMaxLength(length);
// NOTE: below reading byte by byte instead of "int bytesRead = is.read(firstBytes, 0, maxBytesOfResponseToLog);"
// because read() guarantees to read a byte
int bytesRead = 0;
int nextByte = 0;
for (int i = 0; (i < length) && (nextByte >= 0); i++) {
nextByte = read();
if (nextByte >= 0) {
buffer[offset + bytesRead++] = (byte) nextByte;
}
}
if (bytesRead > 0) {
((PushbackInputStream) in).unread(buffer, offset, bytesRead);
}
return bytesRead;
}
public byte[] tryRead(int maxBytesToRead) throws IOException {
validateMaxLength(maxBytesToRead);
ByteArrayOutputStream baos = new ByteArrayOutputStream(); // as ByteArrayOutputStream to dynamically allocate internal bytes array instead of allocating possibly large buffer (if maxBytesToRead is large)
// NOTE: below reading byte by byte instead of "int bytesRead = is.read(firstBytes, 0, maxBytesOfResponseToLog);"
// because read() guarantees to read a byte
int nextByte = 0;
for (int i = 0; (i < maxBytesToRead) && (nextByte >= 0); i++) {
nextByte = read();
if (nextByte >= 0) {
baos.write((byte) nextByte);
}
}
byte[] buffer = baos.toByteArray();
if (buffer.length > 0) {
((PushbackInputStream) in).unread(buffer, 0, buffer.length);
}
return buffer;
}
private void validateMaxLength(int length) throws IOException {
if (length > maxPushbackBufferSize) {
throw new IOException(
"Trying to read more bytes than maxBytesToRead. Max bytes: " + maxPushbackBufferSize + ". Trying to read: " +
length);
}
}
}
This class has two methods. One for reading into existing buffer (defintion is analogous to calling public int read(byte b[], int off, int len)
of InputStream class). Second which returns new buffer (this may be more effective if the size of buffer to read is unknown).
Now let's see our class in action:
public class StreamTest2 {
public static void main(String[] args) throws IOException {
byte[] bytes = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
InputStream originalStream = new ByteArrayInputStream(bytes);
byte[] readBytes = getBytes(originalStream, 3);
printBytes(readBytes); // prints: 1 2 3
readBytes = getBytes(originalStream, 3);
printBytes(readBytes); // prints: 4 5 6
// now let's use our TryReadInputStream
originalStream = new ByteArrayInputStream(bytes);
InputStream wrappedStream = new TryReadInputStream(originalStream, 10);
readBytes = ((TryReadInputStream) wrappedStream).tryRead(3); // NOTE: no manual call to "unread"(!) because TryReadInputStream handles this internally
printBytes(readBytes); // prints 1 2 3
readBytes = ((TryReadInputStream) wrappedStream).tryRead(3);
printBytes(readBytes); // prints 1 2 3
readBytes = ((TryReadInputStream) wrappedStream).tryRead(3);
printBytes(readBytes); // prints 1 2 3
// we can also call normal read which will actually read the bytes without "writing them back"
readBytes = getBytes(wrappedStream, 3);
printBytes(readBytes); // prints 1 2 3
readBytes = getBytes(wrappedStream, 3);
printBytes(readBytes); // prints 4 5 6
readBytes = ((TryReadInputStream) wrappedStream).tryRead(3); // now we can try read next bytes
printBytes(readBytes); // prints 7 8 9
readBytes = ((TryReadInputStream) wrappedStream).tryRead(3);
printBytes(readBytes); // prints 7 8 9
}
}
You're seeing firsthand one of the cons of Lua having only one data structure---you have to roll your own. If you stick with Lua you will gradually accumulate a library of functions that manipulate tables in the way you like to do things. My library includes a list-to-set conversion and a higher-order list-searching function:
function table.set(t) -- set of list
local u = { }
for _, v in ipairs(t) do u[v] = true end
return u
end
function table.find(f, l) -- find element v of l satisfying f(v)
for _, v in ipairs(l) do
if f(v) then
return v
end
end
return nil
end
Extracted from the reference How to Iterate Over a Map in Java:
There are several ways of iterating over a Map
in Java. Let's go over the most common methods and review their advantages and disadvantages. Since all maps in Java implement the Map interface, the following techniques will work for any map implementation (HashMap
, TreeMap
, LinkedHashMap
, Hashtable
, etc.)
Method #1: Iterating over entries using a For-Each loop.
This is the most common method and is preferable in most cases. It should be used if you need both map keys and values in the loop.
Map<Integer, Integer> map = new HashMap<Integer, Integer>();
for (Map.Entry<Integer, Integer> entry : map.entrySet()) {
System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());
}
Note that the For-Each loop was introduced in Java 5, so this method is working only in newer versions of the language. Also a For-Each loop will throw NullPointerException
if you try to iterate over a map that is null, so before iterating you should always check for null references.
Method #2: Iterating over keys or values using a For-Each loop.
If you need only keys or values from the map, you can iterate over keySet or values instead of entrySet.
Map<Integer, Integer> map = new HashMap<Integer, Integer>();
// Iterating over keys only
for (Integer key : map.keySet()) {
System.out.println("Key = " + key);
}
// Iterating over values only
for (Integer value : map.values()) {
System.out.println("Value = " + value);
}
This method gives a slight performance advantage over entrySet
iteration (about 10% faster) and is more clean.
Method #3: Iterating using Iterator.
Using Generics:
Map<Integer, Integer> map = new HashMap<Integer, Integer>();
Iterator<Map.Entry<Integer, Integer>> entries = map.entrySet().iterator();
while (entries.hasNext()) {
Map.Entry<Integer, Integer> entry = entries.next();
System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());
}
Without Generics:
Map map = new HashMap();
Iterator entries = map.entrySet().iterator();
while (entries.hasNext()) {
Map.Entry entry = (Map.Entry) entries.next();
Integer key = (Integer)entry.getKey();
Integer value = (Integer)entry.getValue();
System.out.println("Key = " + key + ", Value = " + value);
}
You can also use same technique to iterate over keySet
or values.
This method might look redundant, but it has its own advantages. First of all, it is the only way to iterate over a map in older versions of Java. The other important feature is that it is the only method that allows you to remove entries from the map during iteration by calling iterator.remove()
. If you try to do this during For-Each iteration you will get "unpredictable results" according to Javadoc.
From a performance point of view this method is equal to a For-Each iteration.
Method #4: Iterating over keys and searching for values (inefficient).
Map<Integer, Integer> map = new HashMap<Integer, Integer>();
for (Integer key : map.keySet()) {
Integer value = map.get(key);
System.out.println("Key = " + key + ", Value = " + value);
}
This might look like a cleaner alternative for method #1, but in practice it is pretty slow and inefficient as getting values by a key might be time-consuming (this method in different Map implementations is 20%-200% slower than method #1). If you have FindBugs installed, it will detect this and warn you about inefficient iteration. This method should be avoided.
Conclusion:
If you need only keys or values from the map, use method #2. If you are stuck with older version of Java (less than 5) or planning to remove entries during iteration, you have to use method #3. Otherwise use method #1.
To match anything other than letter or number or letter with diacritics like é
you could try this:
[^\wÀ-úÀ-ÿ]
And to replace:
var str = 'dfj,dsf7é@lfsd .sdklfàj1';
str = str.replace(/[^\wÀ-úÀ-ÿ]/g, '_');
Inspired by the top post with support for diacritics
A simple way to solve this problem is export thePYTHONPATH
variable enviroment. For example, for Python 2.6 in Debian/GNU Linux:
export PYTHONPATH=/usr/lib/python2.6`
In other operating systems, you would first find the location of this module or the socket.py
file.

The equivalent syntax since DataTables 1.10+ is rowCallback
"rowCallback": function( row, data, index ) {
if ( data[2] == "5" )
{
$('td', row).css('background-color', 'Red');
}
else if ( data[2] == "4" )
{
$('td', row).css('background-color', 'Orange');
}
}
One of the previous answers mentions createdRow
. That may give similar results under some conditions, but it is not the same. For example, if you use draw()
after updating a row's data, createdRow
will not run. It only runs once. rowCallback
will run again.
The NA can actually be due to 2 reasons. One is that there is a NA in your data. Another one is due to there being one of the values being constant. This results in standard deviation being equal to zero and hence the cor function returns NA.
Depending on the language you're using it's going to be something simple like
CInt(CDate("1970-1-1") - CDate(Today()))
Ironically enough, yesterday was day 40,000 if you use 1/1/1900 as "day zero" like many computer systems use.
Try preventing the default behaviour if you don't like the incoming key value:
document.querySelector("input").addEventListener("keypress", function (evt) {
if (evt.which < 48 || evt.which > 57)
{
evt.preventDefault();
}
});

Then run it with the command php foobar.php
, it dumps this kind of output to screen:

So you did a PHP POST to www.google.com and sent it some data.
Had the server been programmed to read in the post variables, it could decide to do something different based upon that.

When use them, I make an exhaustive cheatsheet of their methods for your reference:
class ContainerMethods:
def __init__(self):
self.list_methods_11 = {
'Add':{'append','extend','insert'},
'Subtract':{'pop','remove'},
'Sort':{'reverse', 'sort'},
'Search':{'count', 'index'},
'Entire':{'clear','copy'},
}
self.tuple_methods_2 = {'Search':'count','index'}
self.dict_methods_11 = {
'Views':{'keys', 'values', 'items'},
'Add':{'update'},
'Subtract':{'pop', 'popitem',},
'Extract':{'get','setdefault',},
'Entire':{ 'clear', 'copy','fromkeys'},
}
self.set_methods_17 ={
'Add':{['add', 'update'],['difference_update','symmetric_difference_update','intersection_update']},
'Subtract':{'pop', 'remove','discard'},
'Relation':{'isdisjoint', 'issubset', 'issuperset'},
'operation':{'union' 'intersection','difference', 'symmetric_difference'}
'Entire':{'clear', 'copy'}}
Also If you want you result set data in list .please use below LOC:
public List<String> dbselect(String query)
{
List<String> dbdata=new ArrayList<String>();
try {
dbResult=statement.executeQuery(query);
ResultSetMetaData metadata=dbResult.getMetaData();
for(int i=0;i>=metadata.getColumnCount();i++)
{
dbdata.add(dbResult.getString(i));
}
return dbdata;
} catch (SQLException e) {
return null;
}
}
If you throw the exception, the method execution will stop and the exception is thrown to the caller method. throw
always interrupt the execution flow of the current method. a try
/catch
block is something you could write when you call a method that may throw an exception, but throwing an exception just means that method execution is terminated due to an abnormal condition, and the exception notifies the caller method of that condition.
Find this tutorial about exception and how they work - http://docs.oracle.com/javase/tutorial/essential/exceptions/
1.First open your terminal
2.Then update your gem file with command
sudo gem install -n /usr/local/bin cocoapods
3.Then give your project path
cd /your project path
4.Touch the podifle
touch podfile
5.Open your podfile
open -e podfile
6.It will open a podfile like a text edit. Then set your target. For example if you want to set up Google maps then your podfile should be like
use_frameworks!
target 'yourProjectName' do
pod 'GoogleMaps'
end
7.Then install the pod
pod install
There is some basic pattern matching available through using LIKE, where % matches any number and combination of characters, _ matches any one character, and [abc] could match a, b, or c... There is more info on the MSDN site.
For anyone like me finding this question the following might be useful.
I had a similar problem and initially tried using location.go and location.replaceState as suggested in other answers here. However I ran into problems when I had to navigate to another page on the app because the navigation was relative to the current route and the current route wasn't being updated by location.go or location.replaceState (the router doesn't know anything about what these do to the URL)
In essence I needed a solution that DIDN'T reload the page/component when the route parameter changed but DID update the route state internally.
I ended up using query parameters. You can find more about it here: https://angular-2-training-book.rangle.io/handout/routing/query_params.html
So if you need to do something like save an order and get an order ID you can update your page URL like shown below. Updating a centre location and related data on a map would be similar
// let's say we're saving an order. Initally the URL is just blah/orders
save(orderId) {
// [Here we would call back-end to save the order in the database]
this.router.navigate(['orders'], { queryParams: { id: orderId } });
// now the URL is blah/orders?id:1234. We don't reload the orders
// page or component so get desired behaviour of not seeing any
// flickers or resetting the page.
}
and you keep track of it within the ngOnInit method like:
ngOnInit() {
this.orderId = this.route
.queryParamMap
.map(params => params.get('id') || null);
// orderID is up-to-date with what is saved in database now, or if
// nothing is saved and hence no id query paramter the orderId variable
// is simply null.
// [You can load the order here from its ID if this suits your design]
}
If you need to go direct to the order page with a new (unsaved) order you can do:
this.router.navigate(['orders']);
Or if you need to go direct to the order page for an existing (saved) order you can do:
this.router.navigate(['orders'], { queryParams: { id: '1234' } });
Update: As of SQL Server 2016 parsing JSON in TSQL is now possible.
Natively, there is no support. You'll have to use CLR. It is as simple as that, unless you have a huge masochistic streak and want to write a JSON parser in SQL
Normally, folk ask for JSON output from the DB and there are examples on the internet. But into a DB?
try this:
Using jQuery:
You can reset the entire form with:
$("#myform")[0].reset();
Or just the specific field with:
$('#form-id').children('input').val('')
Using JavaScript Without jQuery
<input type="button" value="Submit" id="btnsubmit" onclick="submitForm()">
function submitForm() {
// Get the first form with the name
// Hopefully there is only one, but there are more, select the correct index
var frm = document.getElementsByName('contact-form')[0];
frm.submit(); // Submit
frm.reset(); // Reset
return false; // Prevent page refresh
}
From lambda answer, I have made something closer to the requirements.

Hm, looking at your first set of code, I think you have retrieved (maybe?) the hard drive model. The serial # comes from Win32_PhysicalMedia
.
Get Hard Drive model
ManagementObjectSearcher searcher = new
ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
foreach(ManagementObject wmi_HD in searcher.Get())
{
HardDrive hd = new HardDrive();
hd.Model = wmi_HD["Model"].ToString();
hd.Type = wmi_HD["InterfaceType"].ToString();
hdCollection.Add(hd);
}
Get the Serial Number
searcher = new
ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
int i = 0;
foreach(ManagementObject wmi_HD in searcher.Get())
{
// get the hard drive from collection
// using index
HardDrive hd = (HardDrive)hdCollection[i];
// get the hardware serial no.
if (wmi_HD["SerialNumber"] == null)
hd.SerialNo = "None";
else
hd.SerialNo = wmi_HD["SerialNumber"].ToString();
++i;
}
Hope this helps :)
I was getting the read-only problem even when I was selecting the primary key. I eventually figured out it was a casing problem. Apparently the PK column must be cased the same as defined in the table. using: workbench 6.3 on windows

If you wish to get the innerhtml of the class without the zend you could use this:
$dom = new DomDocument();
$dom->load($filePath);
$classname = 'main-article';
$finder = new DomXPath($dom);
$nodes = $finder->query("//*[contains(concat(' ', normalize-space(@class), ' '), ' $classname ')]");
$tmp_dom = new DOMDocument();
foreach ($nodes as $node)
{
$tmp_dom->appendChild($tmp_dom->importNode($node,true));
}
$innerHTML.=trim($tmp_dom->saveHTML());
echo $innerHTML;
Another interesting usecase for split in Hive is when, for example, a column ipname
in the table has a value "abc11.def.ghft.com" and you want to pull "abc11" out:
SELECT split(ipname,'[\.]')[0] FROM tablename;
Never tried it, but git help ignore
suggests that if you put a .gitignore
with *.js
in /public/static
, it will do what you want.
Note: make sure to also check out Joeys' answer below: if you want to ignore files in a specific subdirectory, then a local .gitignore is the right solution (locality is good). However if you need the same pattern to apply to your whole repo, then the ** solution is better.
NSArray * values = [dictionary allValues];
The easiest way to do this, with excellent performance and compatibility with both old and new browsers, is to include either Lo-Dash or Underscore in your page.
Then you can use either _.size(object)
or _.keys(object).length
For your obj.Data
, you could test this with:
console.log( _.size(obj.Data) );
or:
console.log( _.keys(obj.Data).length );
Lo-Dash and Underscore are both excellent libraries; you would find either one very useful in your code. (They are rather similar to each other; Lo-Dash is a newer version with some advantanges.)
Alternatively, you could include this function in your code, which simply loops through the object's properties and counts them:
function ObjectLength( object ) {
var length = 0;
for( var key in object ) {
if( object.hasOwnProperty(key) ) {
++length;
}
}
return length;
};
You can test this with:
console.log( ObjectLength(obj.Data) );
That code is not as fast as it could be in modern browsers, though. For a version that's much faster in modern browsers and still works in old ones, you can use:
function ObjectLength_Modern( object ) {
return Object.keys(object).length;
}
function ObjectLength_Legacy( object ) {
var length = 0;
for( var key in object ) {
if( object.hasOwnProperty(key) ) {
++length;
}
}
return length;
}
var ObjectLength =
Object.keys ? ObjectLength_Modern : ObjectLength_Legacy;
and as before, test it with:
console.log( ObjectLength(obj.Data) );
This code uses Object.keys(object).length
in modern browsers and falls back to counting in a loop for old browsers.
But if you're going to all this work, I would recommend using Lo-Dash or Underscore instead and get all the benefits those libraries offer.
I set up a jsPerf that compares the speed of these various approaches. Please run it in any browsers you have handy to add to the tests.
Thanks to Barmar for suggesting Object.keys
for newer browsers in his answer.
just do it:
$file=Get-Item "C:\temp\file.htm"
$file.Basename
$file.Extension
There is another way, take this as example
Dim sr As String
sr = "6:10"
Rows(sr).Select
All you need to do is to convert your variables iStartRow
, iEndRow
to a string.
y = (y != undefined) ? y : x;
The parenthesis are not necessary, I just add them because I think it's easier to read this way.
/
means the root of the current drive;
./
means the current directory;
../
means the parent of the current directory.
You have to edit httpd.conf
and find this line: Listen 127.0.0.1:80
Then write down your desired IP you set for LAN. Don't use automatic IP.
e.g.: Listen 192.168.137.1:80
I used 192.167.137.1
as my LAN IP of Windows 7. Restart Apache and enjoy sharing.

POJO stands for Plain Old Java Object, and would be used to describe the same things as a "Normal Class" whereas a JavaBean follows a set of rules. Most commonly Beans use getters and setters to protect their member variables, which are typically set to private and have a no-argument public constructor. Wikipedia has a pretty good rundown of JavaBeans: http://en.wikipedia.org/wiki/JavaBeans
POJO is usually used to describe a class that doesn't need to be a subclass of anything, or implement specific interfaces, or follow a specific pattern.
int uniqueId = 0;
int getUniqueId()
{
return uniqueId++;
}
Add synchronized
if you want it to be thread safe.
in c# this is working :D

probably graded as a non-pythonic way to do this but this'll give the result you want in a line:
new_df = pd.DataFrame(zip(email,list))
Result:

PHP file (for example, my_lengthy_script.php)
ini_set('max_execution_time', 300); //300 seconds = 5 minutes
.htaccess file
<IfModule mod_php5.c>
php_value max_execution_time 300
</IfModule>
More configuration options
<IfModule mod_php5.c>
php_value post_max_size 5M
php_value upload_max_filesize 5M
php_value memory_limit 128M
php_value max_execution_time 300
php_value max_input_time 300
php_value session.gc_maxlifetime 1200
</IfModule>
If wordpress, set this in the config.php file,
define('WP_MEMORY_LIMIT', '128M');
If drupal, sites/default/settings.php
ini_set('memory_limit', '128M');
If you are using other frameworks,
ini_set('memory_limit', '128M');
You can increase memory as gigabyte.
ini_set('memory_limit', '3G'); // 3 Gigabytes
259200 means:-
( 259200/(60x60 minutes) ) / 24 hours ===> 3 Days
If you go into any of those locations, then you will find what is defined in those schema. For example, it tells you what is the data type of the ini-method key words value.
Simple Steps:

pip install tensorflow.tensorboard # install tensorboard
pip show tensorflow.tensorboard
# Location: c:\users\<name>\appdata\roaming\python\python35\site-packages
# now just run tensorboard as:
python c:\users\<name>\appdata\roaming\python\python35\site-packages\tensorboard\main.py --logdir=<logidr>
You can use an XMLHttpRequest to load a page into a div (or any other element of your page really). An exemple function would be:
function loadPage(){
if (window.XMLHttpRequest){
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}else{
// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById("ID OF ELEMENT YOU WANT TO LOAD PAGE IN").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("POST","WEBPAGE YOU WANT TO LOAD",true);
xmlhttp.send();
}
If your sever is capable, you could also use PHP to do this, but since you're asking for an HTML5 method, this should be all you need.
The difference between these two approaches is as follows:
Synchronous way:
It waits for each operation to complete, after that only it executes the next operation.
For your query:
The console.log()
command will not be executed until & unless the query has finished executing to get all the result from Database.
Asynchronous way:
It never waits for each operation to complete, rather it executes all operations in the first GO only. The result of each operation will be handled once the result is available.
For your query:
The console.log()
command will be executed soon after the Database.Query()
method. While the Database query runs in the background and loads the result once it is finished retrieving the data.
Use cases
If your operations are not doing very heavy lifting like querying huge data from DB then go ahead with Synchronous way otherwise Asynchronous way.
In Asynchronous way you can show some Progress indicator to the user while in background you can continue with your heavy weight works. This is an ideal scenario for GUI apps.

I know you said that you couldn't install any software, but I'm not sure how tight that restriction is. Anyway, I had the same issue (trying to concatenate two files with presumably the same headers) and I thought I'd provide an alternative answer for others who arrive at this page, since it worked just great for me.
After trying a whole bunch of commands in windows and being severely frustrated, and also trying all sorts of graphical editors that promised to be able to open large files, but then couldn't, I finally got back to my Linux roots and opened my Cygwin prompt. Two commands:
cp file1.csv out.csv
tail -n+2 file2.csv >> out.csv
For file1.csv
800MB and file2.csv
400MB, those two commands took under 5 seconds on my machine. In a Cygwin prompt, no less. I thought Linux commands were supposed to be slow in Cygwin but that approach took far less effort and was way easier than any windows approach I could find.
This is a bit of a pain on Windows. Here's what I do.
Install latest Sun JDK, e.g. 6u11, in path like c:\install\jdk\sun\6u11
, then let the installer install public JRE in the default place (c:\program files\blah
). This will setup your default JRE for the majority of things.
Install older JDKs as necessary, like 5u18 in c:\install\jdk\sun\5u18
, but don't install the public JREs.
When in development, I have a little batch file that I use to setup a command prompt for each JDK version. Essentially just set JAVA_HOME=c:\jdk\sun\JDK_DESIRED
and then set PATH=%JAVA_HOME%\bin;%PATH%
. This will put the desired JDK first in the path and any secondary tools like Ant or Maven can use the JAVA_HOME
variable.
The path is important because most public JRE installs put a linked executable at c:\WINDOWS\System32\java.exe
, which usually overrides most other settings.
I have faced with this problem when DNS server was set to 8.8.8.8 (google's). Actually, the problem was in router, my application tried to connect with server through the google, not locally (for my particular case). I have removed 8.8.8.8 and this solved the issue. I know that this issues solved by CORS settings, but maybe someone will have the same trouble as me

Doing it as a stored procedure does have lot of advantages. You can get the sequence that is inserted into the table using syntax insert into table_name values returning
.
Like:
declare
some_seq_val number;
lv_seq number;
begin
some_seq_val := your_seq.nextval;
insert into your_tab (col1, col2, col3)
values (some_seq_val, val2, val3) returning some_seq_val into lv_seq;
dbms_output.put_line('The inserted sequence is: '||to_char(lv_seq));
end;
/
Or just return some_seq_val
. In case you are not making use of SEQUENCE, and arriving the sequence on some calculation, you can make use of returning into
effectively.

For Firefox:
ProfilesIni profile = new ProfilesIni();
FirefoxProfile myprofile = profile.getProfile("default");
myprofile.setAcceptUntrustedCertificates(true);
myprofile.setAssumeUntrustedCertificateIssuer(true);
WebDriver driver = new FirefoxDriver(myprofile);
For Chrome we can use:
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.switches", Arrays.asList("--ignore-certificate-errors"));
driver = new ChromeDriver(capabilities);
For Internet Explorer we can use:
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
Webdriver driver = new InternetExplorerDriver(capabilities);
This should work:
cat "$API" >> "$CONFIG"
You need to use the >>
operator to append to a file. Redirecting with >

After combining a lot of snippets, I finally found a reuseable solution for Windows, that uses ATL Library, which comes with Visual Studio.
#include <atlstr.h>
void getFiles(CString directory) {
HANDLE dir;
WIN32_FIND_DATA file_data;
CString file_name, full_file_name;
if ((dir = FindFirstFile((directory + "/*"), &file_data)) == INVALID_HANDLE_VALUE)
{
// Invalid directory
}
while (FindNextFile(dir, &file_data)) {
file_name = file_data.cFileName;
full_file_name = directory + file_name;
if (strcmp(file_data.cFileName, ".") != 0 && strcmp(file_data.cFileName, "..") != 0)
{
std::string fileName = full_file_name.GetString();
// Do stuff with fileName
}
}
}
To access the method, just call:
getFiles("i:\\Folder1");
This can be easily handled with pydantic, as it already has this functionality built-in.
Option 1: normal way
from pydantic import BaseModel
class testclass(BaseModel):
value1: str = "a"
value2: str = "b"
test = testclass()
>>> print(test.json(indent=4))
{
"value1": "a",
"value2": "b"
}
Option 2: using pydantic's dataclass
import json
from pydantic.dataclasses import dataclass
from pydantic.json import pydantic_encoder
@dataclass
class testclass:
value1: str = "a"
value2: str = "b"
test = testclass()
>>> print(json.dumps(test, indent=4, default=pydantic_encoder))
{
"value1": "a",
"value2": "b"
}
you can wrap reserved words in square brackets to avoid these kinds of errors:
dbo.TableName.[Date]
I have the same issue with Entity Framework 6.1.3
But with different scenario. My model property is of type nullable DateTime
DateTime? CreatedDate { get; set; }
So I need to query on today's date to check all the record, so this what works for me. Which means I need to truncate both records to get the proper query on DbContext
:
Where(w => DbFunctions.TruncateTime(w.CreatedDate) == DbFunctions.TruncateTime(DateTime.Now);
This code works:
$(".ui-button-text").live(
'hover',
function (ev) {
if (ev.type == 'mouseover') {
$(this).addClass("ui-state-hover");
}
if (ev.type == 'mouseout') {
$(this).removeClass("ui-state-hover");
}
});
While I think this compiler error is a good thing, there is a way you can work around it. Use a condition you know will be true:
public void myMethod(){
someCodeHere();
if(1 < 2) return; // compiler isn't smart enough to complain about this
moreCodeHere();
}
The compiler is not smart enough to complain about that.
If you have robocopy,
robocopy C:\Folder1 D:\Folder2 /COPYALL /E
otherwise,
xcopy /e /v C:\Folder1 D:\Folder2
You can add image to asp.net button. you dont need to use only image button or link button. When displaying button on browser, it is converting to html button as default. So you can use its "Style" properties for adding image. My example is below. I hope it works for you.
Style="background-image:url('Image/1.png');"
You can change image location with using
background-repeat
properties. So you can write a button like below:
<asp:Button ID="btnLogin" runat="server" Text="Login" Style="background-image:url('Image/1.png'); background-repeat:no-repeat"/>
PHP has a built in function called bool chmod(string $filename, int $mode )
private function writeFileContent($file, $content){
$fp = fopen($file, 'w');
fwrite($fp, $content);
fclose($fp);
chmod($file, 0777); //changed to add the zero
return true;
}
Now in c++11 we have
#include <string>
string s = std::to_string(123);
Link to reference: http://en.cppreference.com/w/cpp/string/basic_string/to_string
Not sure if I get you right, but the simplest way would be something like:
<c:if test="${languageBean.locale == 'en'">
<f:selectItems value="#{customerBean.selectableCommands_limited_en}" />
</c:if>
Just a quick copy and paste from an app of mine...
HTH
Yes;
git commit FILE
will commit just FILE. Then you can use
git reset --hard
to undo local changes in other files.
There may be other ways too that I don't know about...
edit: or, as NicDumZ said, git-checkout just the files you want to undo the changes on (the best solution depends on wether there are more files to commit or more files to undo :-)
With sdk, you can't write to the root of internal storage. This cause your error.
Edit :
Based on your code, to use internal storage with sdk:
final File dir = new File(context.getFilesDir() + "/nfs/guille/groce/users/nicholsk/workspace3/SQLTest");
dir.mkdirs(); //create folders where write files
final File file = new File(dir, "BlockForTest.txt");
The saga continues with the Windows 10 version. I had to install Win Debug Tools on clean Windows 10 OS with Visual Studio 2015.
To make a long story short, just follow the instructions in the link provided by David Black. After downloading the files, instead of running the SDK installer, browse to the installers directory and execute the msi files directly.
I wonder how many man hours have been lost through the last decade because of MS sloppiness in regards to WDK/SDK installation?
You can also create a HTML alert template like this:
<div class="alert alert-info" id="alert_template" style="display: none;">
<button type="button" class="close">×</button>
</div>
And so you can do in JavaScript this here:
$("#alert_template button").after('<span>Some text</span>');
$('#alert_template').fadeIn('slow');
Which is in my opinion cleaner and faster. In addition you stick to Twitter Bootstrap standards when calling fadeIn()
.
To guarantee that this alert template works also with multiple calls (so it doesn't add the new message to the old one), add this here to your JavaScript:
$('#alert_template .close').click(function(e) {
$("#alert_template span").remove();
});
So this call removes the span element every time you close the alert via the x-button.
According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison
Doing either
mystring == yourstring
or
mystring.eql? yourstring
Are equivalent.
With Simple Java Mail 5.0.0 (simplejavamail.org) it is very straightforward and the library will take care of all the Session properties for you.
Here's an example using Google's SMTP servers:
Email email = EmailBuilder.startingBlank()
.from("lollypop", "[email protected]")
.to("C.Cane", "[email protected]")
.withSubject("hey")
.withPlainText("We should meet up!")
.withHTMLText("<b>We should meet up!</b>")
.buildEmail();
MailerBuilder.withSMTPServer("smtp.gmail.com", 25, "user", "pass", SMTP_TLS)
.buildMailer()
.sendMail(email);
MailerBuilder.withSMTPServer("smtp.gmail.com", 587, "user", "pass", SMTP_TLS)
.buildMailer()
.sendMail(email);
MailerBuilder.withSMTPServer("smtp.gmail.com", 465, "user", "pass", SMTP_SSL)
.buildMailer()
.sendMail(email);
If you have two-factor login turned on, you need to generate an application specific password from your Google account.
You should be able to split('\n').length and get the line breaks.
update: this works on FF/Chrome but not IE.
<html>
<head>
<script src="jquery-1.3.2.min.js"></script>
<script>
$(document).ready(function() {
var arr = $("div").text().split('\n');
for (var i = 0; i < arr.length; i++)
$("div").after(i + '=' + arr[i] + '<br/>');
});
</script>
</head>
<body>
<div>One
Two
Three</div>
</body>
</html>
it is always good to restrict the DOM search. so better to use a parent also, so that the entire DOM won't be traversed.
IT IS VERY FAST
<div id="radioBtnDiv">
<input name="myButton" type="radio" class="radioClass" value="manual" checked="checked"/>
<input name="myButton" type="radio" class="radioClass" value="auto" checked="checked"/>
</div>
$("input[name='myButton']",$('#radioBtnDiv')).change(
function(e)
{
// your stuffs go here
});
Of course, the following code won't give you random numbers but pseudo random number. Use the following code
#define QUICK_RAND(m,n) m + ( std::rand() % ( (n) - (m) + 1 ) )
For example:
int myRand = QUICK_RAND(10, 20);
You must call
srand(time(0)); // Initialize random number generator.
otherwise the numbers won't be near random.
I split var all over the places, the only questionable places for me are internal short types, e.g. I prefer int i = 3;
over var i = 3;
Delete old Db when uninstall the app.
Setting android:allowBackup="false" in the application tag in AndroidManifest.xml fixed the problem. It seems that for some weird reason the Android OS was restoring from a backup every time I deployed the app.
Thanks to this post, I finally found the solution. Here is the code:
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebResourceError;
import android.webkit.WebResourceRequest;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
import android.annotation.TargetApi;
public class Main extends Activity {
private WebView mWebview ;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
@SuppressWarnings("deprecation")
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
@TargetApi(android.os.Build.VERSION_CODES.M)
@Override
public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
// Redirect to deprecated method, so you can use it in all SDK versions
onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
}
});
mWebview .loadUrl("http://www.google.com");
setContentView(mWebview );
}
}
Trigger DataTable search function after initializing DataTable with a blank string in it. It will automatically adjust misalignment of thead
with tbody
.
$( document ).ready(function()
{
$('#monitor_data_voyage').DataTable( {
scrollY:150,
bSort:false,
bPaginate:false,
sScrollX: "100%",
scrollX: true,
} );
setTimeout( function(){
$('#monitor_data_voyage').DataTable().search( '' ).draw();
}, 10 );
});
I wouldn't recommend OpenPOP. I just spent a few hours debugging an issue - OpenPOP's POPClient.GetMessage() was mysteriously returning null. I debugged this and found it was a string index bug - see the patch I submitted here: http://sourceforge.net/tracker/?func=detail&aid=2833334&group_id=92166&atid=599778. It was difficult to find the cause since there are empty catch{} blocks that swallow exceptions.
Also, the project is mostly dormant... the last release was in 2004.
For now we're still using OpenPOP, but I'll take a look at some of the other projects people have recommended here.
My initial guess without knowing the data would be that the UserNameToVerify is not a multiple of 4 in length. Check out the FromBase64String on msdn.
// Ok
byte[] b1 = Convert.FromBase64String("CoolDude");
// Exception
byte[] b2 = Convert.FromBase64String("MyMan");
If you want to be sure that these files are properly refreshed by Chrome for all users, then you need to have must-revalidate
in the Cache-Control
header. This will make Chrome re-check files to see if they need to be re-fetched.
Recommend the following response header:
Cache-Control: must-validate
This tells Chrome to check with the server, and see if there is a newer file. If there is a newer file, it will receive it in the response. If not, it will receive a 304 response, and the assurance that the one in the cache is up to date.
If you do NOT set this header, then in the absence of any other setting that invalidates the file, Chrome will never check with the server to see if there is a newer version.
Here is a blog post that discusses the issue further.
I did this before using the MSXML library and then using the XMLHttpRequest object, see here.
Don't include header.php. You should not output HTML when you are going to redirect.
Make a new file, eg. "pre.php". Put this in it:
<?php
include('class.user.php');
include('class.Connection.php');
?>
Then in header.php, include that, in stead of including the two other files. In form.php, include pre.php in stead of header.php.
I assume you're looking for "1.4 MB" instead of "1468006 bytes"?
I don't think there is a built-in way to do that in .NET. You'll need to just figure out which unit is appropriate, and format it.
Edit: Here's some sample code to do just that:
In general, fixing corrupt objects can be pretty difficult. However, in this case, we're confident that the problem is an aborted transfer, meaning that the object is in a remote repository, so we should be able to safely remove our copy and let git get it from the remote, correctly this time.
The temporary object file, with zero size, can obviously just be removed. It's not going to do us any good. The corrupt object which refers to it, d4a0e75...
, is our real problem. It can be found in .git/objects/d4/a0e75...
. As I said above, it's going to be safe to remove, but just in case, back it up first.
At this point, a fresh git pull
should succeed.
...assuming it was going to succeed in the first place. In this case, it appears that some local modifications prevented the attempted merge, so a stash
, pull
, stash pop
was in order. This could happen with any merge, though, and didn't have anything to do with the corrupted object. (Unless there was some index cleanup necessary, and the stash did that in the process... but I don't believe so.)
Another option is use Oracle SQL Developer. Two steps as below:
(1) First of all, you need to connect SQL Developer to your PostgreSQL database.
(2) Then you can generate an entity-relationship (ER) diagram using SQL Developer
For tomcat you can increase the permGem space by using
-XX:MaxPermSize=128m
For this you need to create (if not already exists) a file named setenv.sh in tomcat/bin folder and include following line in it
export JAVA_OPTS="-XX:MaxPermSize=128m"
Reference : http://wiki.razuna.com/display/ecp/Adjusting+Memory+Settings+for+Tomcat
Use this Layout in your xml file
<LinearLayout
android:id="@+id/contacts_type"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="gone">
</LinearLayout>
Define your layout in .class file
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.contacts_type);
Now if you want to display this layout just write
linearLayout.setVisibility(View.VISIBLE);
and if you want to hide layout just write
linearLayout.setVisibility(View.INVISIBLE);
This's simple and works like a charm :) just declare your enum like this and you can use it on HTML template
statusEnum: typeof StatusEnum = StatusEnum;
You can add style for :after a like html code.
For example:
var value = 22;
body.append('<style>.wrapper:after{border-top-width: ' + value + 'px;}</style>');
If a linked server is not allowed by your dba, you can use OPENROWSET. Books Online will provide the syntax you need.
If you are using App.Config to store values in <add Key="" Value="" />
or CustomSections section use ConfigurationManager class, else use XMLDocument class.
For example:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="server" value="192.168.0.1\xxx"/>
<add key="database" value="DataXXX"/>
<add key="username" value="userX"/>
<add key="password" value="passX"/>
</appSettings>
</configuration>
You could use the code posted on CodeProject
The beauty of the React Native is that it supports lots of JS libraries like Moment.js. Using moment.js would be a better/easier way to handle date/time instead coding from scratch
just run this in the terminal (yarn add moment
also works if using React's built-in package manager):
npm install moment --save
And in your React Native js page:
import Moment from 'moment';
render(){
Moment.locale('en');
var dt = '2016-05-02T00:00:00';
return(<View> {Moment(dt).format('d MMM')} </View>) //basically you can do all sorts of the formatting and others
}
You may check the moment.js official docs here https://momentjs.com/docs/
select t2.*
from t1 join t2 on t2.url='site.com/path/%' + cast(t1.id as varchar) + '%/more'
where t1.id > 9000
Using concat like suggested is even better though
This should work for you:
var movies = _db.Movies.OrderBy(c => c.Category).ThenBy(n => n.Name)
If you don't use the --global
parameter it will set the variables for the current project only.
Take a look at the Java™ Tutorials by Oracle.
But basically, as dacwe said, use break
.
If you can it is often clearer to avoid using break and put the check as a condition of the while loop, or using something like a do while loop. This isn't always possible though.
My two cents: Discriminative approaches highlight differences Generative approaches do not focus on differences; they try to build a model that is representative of the class. There is an overlap between the two. Ideally both approaches should be used: one will be useful to find similarities and the other will be useful to find dis-similarities.
For small values, casting is enough:
long l = 42;
int i = (int) l;
However, a long
can hold more information than an int
, so it's not possible to perfectly convert from long
to int
, in the general case. If the long
holds a number less than or equal to Integer.MAX_VALUE
you can convert it by casting without losing any information.
For example, the following sample code:
System.out.println( "largest long is " + Long.MAX_VALUE );
System.out.println( "largest int is " + Integer.MAX_VALUE );
long x = (long)Integer.MAX_VALUE;
x++;
System.out.println("long x=" + x);
int y = (int) x;
System.out.println("int y=" + y);
produces the following output on my machine:
largest long is 9223372036854775807
largest int is 2147483647
long x=2147483648
int y=-2147483648
Notice the negative sign on y
. Because x
held a value one larger than Integer.MAX_VALUE
, int y
was unable to hold it. In this case, it wrapped around to the negative numbers.
If you wanted to handle this case yourself, you might do something like:
if ( x > (long)Integer.MAX_VALUE ) {
// x is too big to convert, throw an exception or something useful
}
else {
y = (int)x;
}
All of this assumes positive numbers. For negative numbers, use MIN_VALUE
instead of MAX_VALUE
.
For the new Criteria since version Hibernate 5.2:
CriteriaBuilder criteriaBuilder = getSession().getCriteriaBuilder();
CriteriaQuery<SomeClass> criteriaQuery = criteriaBuilder.createQuery(SomeClass.class);
Root<SomeClass> root = criteriaQuery.from(SomeClass.class);
Path<Object> expressionA = root.get("A");
Path<Object> expressionB = root.get("B");
Predicate predicateAEqualX = criteriaBuilder.equal(expressionA, "X");
Predicate predicateBInXY = expressionB.in("X",Y);
Predicate predicateLeft = criteriaBuilder.and(predicateAEqualX, predicateBInXY);
Predicate predicateAEqualY = criteriaBuilder.equal(expressionA, Y);
Predicate predicateBEqualZ = criteriaBuilder.equal(expressionB, "Z");
Predicate predicateRight = criteriaBuilder.and(predicateAEqualY, predicateBEqualZ);
Predicate predicateResult = criteriaBuilder.or(predicateLeft, predicateRight);
criteriaQuery
.select(root)
.where(predicateResult);
List<SomeClass> list = getSession()
.createQuery(criteriaQuery)
.getResultList();
Just create a new theme in res/values/styles.xml where you change the "colorPrimaryDark" which is the color of the status bar:
<style name="AppTheme.GrayStatusBar" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimaryDark">@color/colorGray</item>
</style>
And modify the activity theme in AndroidManifest.xml to the one you want, on the next activity you can change the color back to the original one by selecting the original theme:
<activity
android:name=".LoginActivity"
android:theme="@style/AppTheme.GrayStatusBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
This is how your res/values/colors.xml should look like:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#3F51B5</color>
<color name="colorPrimaryDark">#303F9F</color>
<color name="colorAccent">#c6d6f0</color>
<color name="colorGray">#757575</color>
</resources>
From the docs
To whitelist an entire hash of parameters, the permit! method can be used
params.require(:log_entry).permit!
Nested attributes are in the form of a hash. In my app, I have a Question.rb model accept nested attributes for an Answer.rb model (where the user creates answer choices for a question he creates). In the questions_controller, I do this
def question_params
params.require(:question).permit!
end
Everything in the question hash is permitted, including the nested answer attributes. This also works if the nested attributes are in the form of an array.
Having said that, I wonder if there's a security concern with this approach because it basically permits anything that's inside the hash without specifying exactly what it is, which seems contrary to the purpose of strong parameters.

function dedupe(arr, compFn){

arr.map(a => {if(!res.find(b => compFn(a, b))) res.push(a)});

i found out why my first row was default selected and found out how to not select it by default.
By default my datagridview was the object with the first tab-stop on my windows form. Making the tab stop first on another object (maybe disabling tabstop for the datagrid at all will work to) disabled selecting the first row
To swap characters in a string a of position l and r
def swap(a, l, r):
a = a[0:l] + a[r] + a[l+1:r] + a[l] + a[r+1:]
return a
Example: swap("aaabcccdeee", 3, 7) returns "aaadcccbeee"
The first way would be preferred to the second.
This is because the header file will show that the parameter is optional and what its default value will be. Additionally, this will ensure that the default value will be the same, no matter the implementation of the corresponding .cpp file.
In the second way, there is no guarantee of a default value for the second parameter. The default value could change, depending on how the corresponding .cpp file is implemented.
You can define instance method for js class, via prototype of the constructor.
Following is the sample code:
// BaseClass
var BaseClass = function(name) {
// instance property
this.name = name;
};
// instance method
BaseClass.prototype.getName = function() {
return this.name;
};
BaseClass.prototype.setName = function(name) {
return this.name = name;
};
// test - start
function test() {
var b1 = new BaseClass("b1");
var b2 = new BaseClass("b2");
console.log(b1.getName());
console.log(b2.getName());
b1.setName("b1_new");
console.log(b1.getName());
console.log(b2.getName());
}
test();
// test - end
And, this should work for any browser, you can also simply use nodejs to run this code.

I like to use the "Line" control. It gives you exact control over where the separator starts and ends. Although it isn't exactly a separator, it functions is the same way, especially in a StackPanel.
The line control works within a grid too. I prefer to use the StackPanel because you don't have to worry about different controls overlapping.
<StackPanel Orientation="Horizontal">
<Button Content="Button 1" Height="20" Width="70"/>
<Line X1="0" X2="0" Y1="0" Y2="20" Stroke="Black" StrokeThickness="0.5" Margin="5,0,10,0"/>
<Button Content="Button 2" Height="20" Width="70"/>
</StackPanel>
X1 = x starting position (should be 0 for a vertical line)
X2 = x ending position (X1 = X2 for a vertical line)
Y1 = y starting position (should be 0 for a vertical line)
Y2 = y ending position (Y2 = desired line height)
I use "margin" to add padding on any side of the vertical line. In this instance, there are 5 pixels on the left and 10 pixels on the right of the vertical line.
Since the line control lets you pick the x and y coordinates of the start and end of the line, you can also use it for horizontal lines and lines at any angle in between.
UPDATED
After few research, best solution was to use that info another stackoverflow thread to avoid ctrl+z input and also from the scree output.
So, instead of php -a
you should use call "php.exe" -f NAMED_SCRIPT.php
OLD Readline not possible under Windows, so none of existent php shells written in php will work. But there's a workaround using -a interactive mode.
2 commmon problems here. You cannot see result until executes CTRL Z command to indicate the final of code/file like EOF. When you do, result in most cases is printed result and fast closed window. Anyway, you will be returned to cmd not the -a interactive mode.
Save this content into a .bat file, and define your PHP PATH into Windows variables, or modify php.exe to "full path to exe" instead:
::
:: PHP Shell launch wrapper
::
@ECHO off
call "php.exe" -a
echo.
echo.
call "PHP Shell.bat"
This is a simple Batch launching -a mode of php.exe. When it launchs php, stop script even no pause is wrote because is "into" the interactive waiting for input. When you hit CTRL Z, gets the SIGSTEP (next step) not the SIGSTOP (close, CTRL+C usually), then read the next intruction, wich is a recursive call to .bat itself. Because you're always into PHP -a mode, no exit command. You must use CTRL+C or hit the exit cross with mouse. (No alt+f4)
You can also use "Bat to Exe" converter to easy use.
What I'm missing in the other answers is a reference to how this relates to co- and contravariance and sub- and supertypes (that is, polymorphism) in general and to Java in particular. This may be well understood by the OP, but just in case, here it goes:
If you have a class Automobile
, then Car
and Truck
are their subtypes. Any Car can be assigned to a variable of type Automobile, this is well-known in OO and is called polymorphism. Covariance refers to using this same principle in scenarios with generics or delegates. Java doesn't have delegates (yet), so the term applies only to generics.
I tend to think of covariance as standard polymorphism what you would expect to work without thinking, because:
List<Car> cars;
List<Automobile> automobiles = cars;
// You'd expect this to work because Car is-a Automobile, but
// throws inconvertible types compile error.
The reason of the error is, however, correct: List<Car>
does not inherit from List<Automobile>
and thus cannot be assigned to each other. Only the generic type parameters have an inherit relationship. One might think that the Java compiler simply isn't smart enough to properly understand your scenario there. However, you can help the compiler by giving him a hint:
List<Car> cars;
List<? extends Automobile> automobiles = cars; // no error
The reverse of co-variance is contravariance. Where in covariance the parameter types must have a subtype relationship, in contravariance they must have a supertype relationship. This can be considered as an inheritance upper-bound: any supertype is allowed up and including the specified type:
class AutoColorComparer implements Comparator<Automobile>
public int compare(Automobile a, Automobile b) {
// Return comparison of colors
}
This can be used with Collections.sort:
public static <T> void sort(List<T> list, Comparator<? super T> c)
// Which you can call like this, without errors:
List<Car> cars = getListFromSomewhere();
Collections.sort(cars, new AutoColorComparer());
You could even call it with a comparer that compares objects and use it with any type.
A bit OT perhaps, you didn't ask, but it helps understanding answering your question. In general, when you get something, use covariance and when you put something, use contravariance. This is best explained in an answer to Stack Overflow question How would contravariance be used in Java generics?.
List<? extends Map<String, String>>
You use extends
, so the rules for covariance applies. Here you have a list of maps and each item you store in the list must be a Map<string, string>
or derive from it. The statement List<Map<String, String>>
cannot derive from Map
, but must be a Map
.
Hence, the following will work, because TreeMap
inherits from Map
:
List<Map<String, String>> mapList = new ArrayList<Map<String, String>>();
mapList.add(new TreeMap<String, String>());
but this will not:
List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new TreeMap<String, String>());
and this will not work either, because it does not satisfy the covariance constraint:
List<? extends Map<String, String>> mapList = new ArrayList<? extends Map<String, String>>();
mapList.add(new ArrayList<String>()); // This is NOT allowed, List does not implement Map
This is probably obvious, but you may have already noted that using the extends
keyword only applies to that parameter and not to the rest. I.e., the following will not compile:
List<? extends Map<String, String>> mapList = new List<? extends Map<String, String>>();
mapList.add(new TreeMap<String, Element>()) // This is NOT allowed
Suppose you want to allow any type in the map, with a key as string, you can use extend
on each type parameter. I.e., suppose you process XML and you want to store AttrNode, Element etc in a map, you can do something like:
List<? extends Map<String, ? extends Node>> listOfMapsOfNodes = new...;
// Now you can do:
listOfMapsOfNodes.add(new TreeMap<Sting, Element>());
listOfMapsOfNodes.add(new TreeMap<Sting, CDATASection>());
Something like this should solve your problem:
$.getDocHeight = function(){
var D = document;
return Math.max(Math.max(D.body.scrollHeight, D.documentElement.scrollHeight), Math.max(D.body.offsetHeight, D.documentElement.offsetHeight), Math.max(D.body.clientHeight, D.documentElement.clientHeight));
};
alert( $.getDocHeight() );
Ps: Call that function every time you need it, the alert is for testing purposes..
I too was looking for a fast way to convert decimal number to another base in the range of [2..36] so I developed the following code. Its simple to follow and uses a Stringbuilder object as a proxy for a character buffer that we can index character by character. The code appears to be very fast compared to alternatives and a lot faster than initialising individual characters in a character array.
For your own use you might prefer to: 1/ Return a blank string rather than throw an exception. 2/ remove the radix check to make the method run even faster 3/ Initialise the Stringbuilder object with 32 '0's and remove the the line result.Remove( 0, i );. This will cause the string to be returned with leading zeros and further increase the speed. 4/ Make the Stringbuilder object a static field within the class so no matter how many times the DecimalToBase method is called the Stringbuilder object is only initialised the once. If you do this change 3 above would no longer work.
I hope someone finds this useful :)
AtomicParadox
static string DecimalToBase(int number, int radix)
{
// Check that the radix is between 2 and 36 inclusive
if ( radix < 2 || radix > 36 )
throw new ArgumentException("ConvertToBase(int number, int radix) - Radix must be between 2 and 36.");
// Create a buffer large enough to hold the largest int value represented in binary digits
StringBuilder result = new StringBuilder(" "); // 32 spaces
// The base conversion calculates the digits in reverse order so use
// an index to point to the last unused space in our buffer
int i = 32;
// Convert the number to the new base
do
{
int remainder = number % radix;
number = number / radix;
if(remainder <= 9)
result[--i] = (char)(remainder + '0'); // Converts [0..9] to ASCII ['0'..'9']
else
result[--i] = (char)(remainder + '7'); // Converts [10..36] to ASCII ['A'..'Z']
} while ( number > 0 );
// Remove the unwanted padding from the front of our buffer and return the result
// Note i points to the last unused character in our buffer
result.Remove( 0, i );
return (result.ToString());
}
The answers here helped me up to a point, but I had a problem on HTML5 Number input fields when clicking the up/down buttons in Chrome.
If you click one of the buttons, and left the mouse over the button the number would keep changing as if you were holding the mouse button because the mouseup was being thrown away.
I solved this by removing the mouseup handler as soon as it had been triggered as below:
$("input:number").focus(function () {
var $elem = $(this);
$elem.select().mouseup(function (e) {
e.preventDefault();
$elem.unbind(e.type);
});
});
Hope this helps people in the future...
You add html invisible layer over the form. For instance
<div class="coverContainer">
<form></form>
</div>
and style:
.coverContainer{
width: 100%;
height: 100%;
z-index: 100;
background: rgba(0,0,0,0);
position: absolute;
}
Ofcourse user can hide this layer in web browser.
If you are using Express as back-end you just have to install cors and import and use it in app.use(cors());. If it is not resolved then try switching ports. It will surely resolve after switching ports
I ran in the same situation and the script was correctly loading in safe mode. However, disabling all the Add-ons and other Firefox security features didn't help. One thing I tried, and this was the solution in my case, was to temporary disable the cache from the developer window for this particular request. After I saw this was the cause, I wiped out the cache for that site and everything started word normally.
See my jsFiddle here: http://jsfiddle.net/fuDBL/
Whenever you change the email field, the link is updated automatically. This requires a small amount of jQuery. So now your form will work as needed, but your link will be updated dynamically so that when someone clicks on it, it contains what they entered in the email field. You should validate the input on the receiving page.
$('input[name="email"]').change(function(){
$('#regLink').attr('href')+$('input[name="email"]').val();
});
You can't do that. You could try telling your problem from a more high level point of view (i.e. what exactly do you want to accomplish with the casted variable) for a different solution.
You could go with something like this:
public abstract class Message {
// ...
}
public class Message<T> : Message {
}
public abstract class MessageProcessor {
public abstract void ProcessMessage(Message msg);
}
public class SayMessageProcessor : MessageProcessor {
public override void ProcessMessage(Message msg) {
ProcessMessage((Message<Say>)msg);
}
public void ProcessMessage(Message<Say> msg) {
// do the actual processing
}
}
// Dispatcher logic:
Dictionary<Type, MessageProcessor> messageProcessors = {
{ typeof(Say), new SayMessageProcessor() },
{ typeof(string), new StringMessageProcessor() }
}; // properly initialized
messageProcessors[msg.GetType().GetGenericArguments()[0]].ProcessMessage(msg);
I'd like to point out that the accepted comment by Dan Abramov is correct except we experienced a strange issue when using the react-router-redux package along with this approach. Our fix was to not set state to undefined
but rather still use the current routing reducer. So I would suggest implementing the solution below if you are using this package
const rootReducer = (state, action) => {
if (action.type === 'USER_LOGOUT') {
const { routing } = state
state = { routing }
}
return appReducer(state, action)
}
Sample code you can use to let Tika take care of container files for you. http://wiki.apache.org/tika/RecursiveMetadata
Form what I can tell, the accepted solution will not work for cases where there are nested zip files. Tika, however will take care of such situations as well.
CREATE TABLE dbo.tblUsers
(
ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
UserID AS 'UID' + RIGHT('00000000' + CAST(ID AS VARCHAR(8)), 8) PERSISTED,
[Name] VARCHAR(50) NOT NULL,
)

You can use \centering
with your parbox to do this.
(Sorry for the Google cached link; the original one I had doesn't work anymore.)
You could just simply do the following
In your js
$scope.id = 0;
In your template
<div id="number-{{$scope.id}}"></div>
which will render
<div id="number-0"></div>
It is not necessary to concatenate inside double curly brackets.
