Components should start with capital letters. Also remember to change the first letter in the line to export!
For anybody facing a similar issue at this point in time, all you need to do is update your Android Studio to the latest version
I solved it by deleting "/.idea/libraries" from project. Thanks
I got this error message but was a really basic mistake, I had copy/pasted another Component as a template, removed everything from render() then imported it and added it to the parent JSX but hadn't yet renamed the component class. So then the error looked like it was coming from another component which I spent a while trying to debug it before working out it wasn't actually that Component throwing the error! Would have been helpful to have the filename as part of the error message. Hope this helps someone.
Oh a side note note I'm not sure anyone mentioned that returning undefined
will throw the error:
render() {
return this.foo // Where foo is undefined.
}
There is no need to use angular http, you can get with js native functions

in my case:: I was using kotlin extensions
to access and bind my views, I had recently moved a view
to another screen and forgot to remove its reference from the previous fragment that caused this error.
kotlin synthetic extensions
are not compile time safe. I really loved this but apparently in big projects, if this happens again I'm surely going to get a heart attack.
You can do as follows:
Select Format(test.Time, 'yyyyMMdd')
From TableTest test
Swift 3, and now Swift 4, have replaced many "stringly-typed" APIs with struct
"wrapper types", as is the case with NotificationCenter. Notifications are now identified by a struct Notfication.Name
rather than by String
. For more details see the now legacy Migrating to Swift 3 guide
Swift 2.2 usage:
// Define identifier
let notificationIdentifier: String = "NotificationIdentifier"
// Register to receive notification
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(YourClassName.methodOfReceivedNotification(_:)), name: notificationIdentifier, object: nil)
// Post a notification
NSNotificationCenter.defaultCenter().postNotificationName(notificationIdentifier, object: nil)
Swift 3 & 4 usage:
// Define identifier
let notificationName = Notification.Name("NotificationIdentifier")
// Register to receive notification
NotificationCenter.default.addObserver(self, selector: #selector(YourClassName.methodOfReceivedNotification), name: notificationName, object: nil)
// Post notification
NotificationCenter.default.post(name: notificationName, object: nil)
// Stop listening notification
NotificationCenter.default.removeObserver(self, name: notificationName, object: nil)
All of the system notification types are now defined as static constants on Notification.Name
; i.e. .UIApplicationDidFinishLaunching
, .UITextFieldTextDidChange
, etc.
You can extend Notification.Name
with your own custom notifications in order to stay consistent with the system notifications:
// Definition:
extension Notification.Name {
static let yourCustomNotificationName = Notification.Name("yourCustomNotificationName")
}
// Usage:
NotificationCenter.default.post(name: .yourCustomNotificationName, object: nil)
Swift 4.2 usage:
Same as Swift 4, except now system notifications names are part of UIApplication. So in order to stay consistent with the system notifications you can extend UIApplication
with your own custom notifications instead of Notification.Name :
// Definition:
UIApplication {
public static let yourCustomNotificationName = Notification.Name("yourCustomNotificationName")
}
// Usage:
NotificationCenter.default.post(name: UIApplication.yourCustomNotificationName, object: nil)
Below code changes to 'datetime' type and also formats in the given format string. Works well!
df['DOB']=pd.to_datetime(df['DOB'].dt.strftime('%m/%d/%Y'))
I hope it will help someone ! (works on Angular 6)
I had to add lots of select/options dynamically and following worked for me:
<div *ngFor="let option of model.q_options; let ind=index;">
<select
[(ngModel)]="model.q_options[ind].type"
[ngModelOptions]="{standalone: true}"
>
<option
*ngFor="let object of objects"
[ngValue]="object.type"
[selected]="object.type === model.q_options[ind].type"
>{{object.name}}
</option>
</select>
<div [ngSwitch]="model.q_options[ind].type">
( here <div *ngSwitchCase="'text' or 'imagelocal' or etc."> is used to add specific input forms )
</div>
</div>
and in *.ts
// initial state of the model
// q_options in html = NewOption and its second argument is option type
model = new NewQuestion(1, null, 2,
[
new NewOption(0, 'text', '', 1),
new NewOption(1, 'imagelocal', '', 1)
]);
// dropdown options
objects = [
{type: 'text', name: 'text'},
{type: 'imagelocal', name: 'image - local file'},
{type: 'imageurl', name: 'image URL'}
( and etc.)
];
When user adds one more 'input option' (pls do not confuse 'input option' with select/options - select/options are static here) specific select/option, selected by the user earlier, is preserved on each/all dynamically added 'input option's select/options.
I have disabled Instant Run feature from the preferences and the issue was solved.
After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.
It's incorrect to use zeros in date or in datetime, just put null instead of zeros.
this is how I implement it .
let dictionary = self.convertStringToDictionary(responceString)
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "SOCKET_UPDATE"), object: dictionary)
In my case, i got this error trying to get an object on an S3 bucket folder. But in that folder my object was not here (i put the wrong folder), so S3 send this message. Hope it could help you too.
Let me elaborate: Multidex is basically a tool that comes with Android, and if you set it to true, apps with >64,000 methods are able to compile using a slightly altered build process. However you only need to use multidex if your error looks like this:
trouble writing output: Too many field references: 131000; max is 65536. You may try using --multi-dex option.
or like this
Conversion to Dalvik format failed: Unable to execute dex: method ID not in [0, 0xffff]: 65536
But that is not the case here! The problem here (for me atleast) is being caused by your build.gradle file's dependencies.
THE SOLUTION: Utilize specific dependencies—don't just import an entire section of dependencies!
For example, if you need the Play Services dependency for location, only import it for location.
compile 'com.google.android.gms:play-services-location:11.0.4'
compile 'com.google.android.gms:play-services'
Another issue that could be causing this may be some sort of external library you are using, that is referencing a prior version of your dependency. Follow these steps in that case:
I know this question is old, but I need to get this answer out there, because using multidex for no reason could potentially cause ANR's for your app! ONLY use multidex if you're sure you need it, and you understand what it is.
I myself spent hours trying to resolve this issue without multidex, and I just wanted to share my findings—hope this helps
Well, the problem you have is wrong line ending/encoding for notepad. Notepad uses Windows' line endings - \r\n
and you use \n
.
I had this problem when trying to change directory, using the character _
. The solution was to use a string to change directories.
C:\> cd "my_new_dir"
In my case issue was with wrong path to NDK
.
If your project requires it please check it in menu File -> Project Structure -> SDK Location
:
I was getting this one on this case
...
.then((error: any, response: any) => {
console.info('document error: ', error);
console.info('documenr response: ', response);
return new MyModel();
})
...
on this case making parameters optional would make ts stop complaining
.then((error?: any, response?: any) => {
let suppose we create a table Transactions using SQl server management studio
txn_id int,
txn_type_id varchar(200),
Account_id int,
Amount int,
tDate date
);
with date datatype we can insert values in simple format: 'yyyy-mm-dd'
INSERT INTO transactions (txn_id,txn_type_id,Account_id,Amount,tDate)
VALUES (978, 'DBT', 103, 100, '2004-01-22');
Moreover we can have differet time formats like
DATE - format YYYY-MM-DD
DATETIME - format: YYYY-MM-DD HH:MI:SS
SMALLDATETIME - format: YYYY-MM-DD HH:MI:SS
I managed to fix it finally. The problem is not related to HikariCP.
The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional
or enveloping all the logic in a single call to transactional service method seem to solve the problem.
You have to catch the error just as you're already doing for your save()
call and since you're handling multiple errors here, you can try
multiple calls sequentially in a single do-catch block, like so:
func deleteAccountDetail() {
let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
let request = NSFetchRequest()
request.entity = entityDescription
do {
let fetchedEntities = try self.Context!.executeFetchRequest(request) as! [AccountDetail]
for entity in fetchedEntities {
self.Context!.deleteObject(entity)
}
try self.Context!.save()
} catch {
print(error)
}
}
Or as @bames53 pointed out in the comments below, it is often better practice not to catch the error where it was thrown. You can mark the method as throws
then try
to call the method. For example:
func deleteAccountDetail() throws {
let entityDescription = NSEntityDescription.entityForName("AccountDetail", inManagedObjectContext: Context!)
let request = NSFetchRequest()
request.entity = entityDescription
let fetchedEntities = try Context.executeFetchRequest(request) as! [AccountDetail]
for entity in fetchedEntities {
self.Context!.deleteObject(entity)
}
try self.Context!.save()
}
I am using JUnit 4, and what worked for me is changing the IntelliJ settings for 'Gradle -> Run Tests Using' from 'Gradle (default)' to 'IntelliJ IDEA'.

If you defined your cell through the Interface Builder, by placing a cell inside your UICollectionView
, or UITableView
:
Make sure you binded the cell with an actual class you created, and very important, that you checked "Inherit module from target"
Spring framework itself handles json conversion when controller is annotated properly.
For eg:
@PutMapping(produces = {"application/json"})
@ResponseBody
public UpdateResponse someMethod(){ //do something
return UpdateResponseInstance;
}
Here spring internally converts the UpdateResponse object to corresponding json string and returns it. In order to do it spring internally uses Jackson library.
If you require a json representation of a model object anywhere apart from controller then you can use objectMapper provided by jackson. Model should be properly annotated for this to work.
Eg:
ObjectMapper mapper = new ObjectMapper();
SomeModelClass someModelObject = someModelRepository.findById(idValue).get();
mapper.writeValueAsString(someModelObject);
I had faced this similar error too. In my case it was one of my picture files in my drawable
folder. Removing the picture that was unused solved the problem for me. So, make sure to remove any unused items from drawable
folder.

You are most likely pushing a string 'NULL'
to the table, rather then an actual NULL
, but other things may be going on as well, an illustration:

TypeScript supports decorators, and using that feature plus a little library called typescript-mix you can use mixins to have multiple inheritance with just a couple of lines
// The following line is only for intellisense to work
interface Shopperholic extends Buyer, Transportable {}
class Shopperholic {
// The following line is where we "extend" from other 2 classes
@use( Buyer, Transportable ) this
price = 2000;
}
Swift 3.
Call this function to get the topmost view controller, then have that view controller present.
func topMostController() -> UIViewController {
var topController: UIViewController = UIApplication.shared.keyWindow!.rootViewController!
while (topController.presentedViewController != nil) {
topController = topController.presentedViewController!
}
return topController
}
Usage:
let topVC = topMostController()
let vcToPresent = self.storyboard!.instantiateViewController(withIdentifier: "YourVCStoryboardID") as! YourViewController
topVC.present(vcToPresent, animated: true, completion: nil)
An easy way to do this is to map
the variable and return each Character
as a String
:
let someText = "hello"
let array = someText.map({ String($0) }) // [String]
The output should be ["h", "e", "l", "l", "o"]
.
I was getting the same error about the SSL certificate when Maven tried to download the necessary modules automatically.
As a remedy, I was attempting to implement Luke's answer above, but found that the DigiCert Global Root CA certificate is already in Java's trusted keystore.
What helped me was adding %JAVA_HOME%\bin
to the Path variable (I am running Windows). And %JAVA_HOME%
is a JDK location, not just a JRE location, since Maven needs a JDK.
I am not certain why it helped, but it did. I am absolutely sure that this was the only thing I changed.
I was struggling with this, my app was installing but not complete (almost 60% I can say) in iOS8, but in iOS7.1 it was working as expected. The error message popped was:
"Cannot install at this time".
Finally Zillan's link helped me to get apple documentation. So, check:
ax.init.itunes.apple.com
is not getting blocked by your firewall/proxy (Just type this address in safari, a blank page must load). As soon as I changed the proxy it installed completely. Hope it will help someone.
It should be simpler!
Duration.between(startLocalDateTime, endLocalDateTime).toMillis();
You can convert millis to whatever unit you like:
String.format("%d minutes %d seconds",
TimeUnit.MILLISECONDS.toMinutes(millis),
TimeUnit.MILLISECONDS.toSeconds(millis) -
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));
Very Simple and no need to code more.
Just add pod 'IQKeyboardManagerSwift'
in your podfile, and in your AppDelegate
page add code below.
import IQKeyboardManagerSwift
and in method didFinishLaunchingWithOptions()
type
IQKeyboardManager.shared.enable = true
that is it. check this video link for better understanding https://youtu.be/eOM94K1ZWN8 Hope this will help you.
You can't define categories (Swift extensions) with new storage; any additional properties must be computed rather than stored. The syntax works for Objective C because @property
in a category essentially means "I'll provide the getter and setter". In Swift, you'll need to define these yourself to get a computed property; something like:
extension String {
public var Foo : String {
get
{
return "Foo"
}
set
{
// What do you want to do here?
}
}
}
Should work fine. Remember, you can't store new values in the setter, only work with the existing available class state.
Hi the problem is in FileDownloader class
urlConnection.setRequestMethod("GET");
urlConnection.setDoOutput(true);
You need to remove the above two lines and everything will work fine. Please mark the question as answered if it is working as expected.

You don't need the date
validator. It doesn't support dd/mm/yyyy format, and that's why you are getting "Please enter a valid date" message for input like 13/01/2014. You already have the dateITA
validator, which uses dd/mm/yyyy format as you need.
Just like the date
validator, your code for dateGreaterThan
and dateLessThan
calls new Date
for input string and has the same issue parsing dates. You can use a function like this to parse the date:
function parseDMY(value) {
var date = value.split("/");
var d = parseInt(date[0], 10),
m = parseInt(date[1], 10),
y = parseInt(date[2], 10);
return new Date(y, m - 1, d);
}
That's all unnecessary logic in partials, reduce it to something like this and process your data in controller/service where it should be
<div ng-repeat="details in myDataSet">
<p>{{ details.Name }}</p>
<p>{{ details.DOB }}</p>
<p>{{details.Payment[0].StatusName}}</p>
<p>{{ details.Gender}}</p>
</div>
JS:
angular.forEach(myDataSet.Payment, function (payment) {
if(payment.Status === 0){
payment.StatusName = 'No Payment';
} else if(payment.Status === 1 || payment.Status === 2){
payment.StatusName = 'Late';
} else if(payment.Status === 3 || payment.Status === 4 || payment.Status === 5){
payment.StatusName = 'Some payment made';
} else if(payment.Status === 6){
payment.StatusName = 'Late and further taken out';
}else{
payment.StatusName = 'Error';
}
})
NSNotificationCenter add observer syntax in Swift 4.0 for iOS 11
NotificationCenter.default.addObserver(self, selector: #selector(keyboardShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
This is for keyboardWillShow notification name type. Other type can be selected from the available option
the Selector is of type @objc func which handle how the keyboard will show ( this is your user function )
In my case, with letsencrypt https, this was caused by using cert.pem
instead of fullchain.pem
as the certificate file on the requested server. See this thread for details.
The PYTHONPATH
is not set properly. Export it using export PYTHONPATH=$PYTHONPATH:/path/to/your/modules
.
Clearly you aren't sending the data with ObjectOutputStream:
you are just writing the bytes.
readObject()
you must write with writeObject().
readUTF()
you must write with writeUTF().
readXXX()
you must write with writeXXX(),
for most values of XXX.There is one more chance to get this exception even we used class name i.e., if we have two classes with same name in different packages. we'll get this problem.
I think hibernate may get ambiguity and throws this exception, so the solution is to use complete qualified name(like com.test.Customerv)
I added this answer that will help in scenario as I mentioned. I got the same scenario got stuck for some time.
Just use requests'
features:
import requests
from requests.adapters import HTTPAdapter
from requests.packages.urllib3.util.retry import Retry
session = requests.Session()
retry = Retry(connect=3, backoff_factor=0.5)
adapter = HTTPAdapter(max_retries=retry)
session.mount('http://', adapter)
session.mount('https://', adapter)
session.get(url)
This will GET
the URL and retry 3 times in case of requests.exceptions.ConnectionError
. backoff_factor
will help to apply delays between attempts to avoid to fail again in case of periodic request quota.
Take a look at requests.packages.urllib3.util.retry.Retry
, it has many options to simplify retries.
Try the format as dd-mon-yyyy, For example 02-08-2016 should be in the format '08-feb-2016'.
Use Statement Fetch Size , if you are retrieving more number of records. like this.
Statement statement = connection.createStatement();
statement.setFetchSize(1000);
Apart from that i dont see an issue with the way you are doing in terms of performance
In terms of Neat. Always use seperate method delegate to map the resultset to POJO object. which can be reused later in the same class
like
private User mapResultSet(ResultSet rs){
User user = new User();
// Map Results

If you have the same name for both columnName and object's fieldName , you could also write reflection utility to load the records back to POJO. and use MetaData to read the columnNames . but for small scale projects using reflection is not an problem. but as i said before there is nothing wrong with the way you are doing.
As described here: Angular NgModelController, you should provide the <input
with the required controller ngModel
<input submit-required="true" ng-model="user.Name"></input>
You can also use "shouldReceiveTouch" method of UIGestureRecognizer
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch: (UITouch *)touch {
UIView *view = touch.view;
NSLog(@"%d", view.tag);
}
Dont forget to set delegate of your gesture recognizer.
Try below piece of code.
this.dataGridView1.RefreshEdit();
The snippet you're showing doesn't seem to be directly responsible for the error.
This is how you can CAUSE the error:
namespace MyNameSpace
{
int i; <-- THIS NEEDS TO BE INSIDE THE CLASS
class MyClass
{
...
}
}
If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }
.
i have the same problem on ubuntu 15.10. Please try download plugin locally e.g. https://github.com/lmenezes/elasticsearch-kopf/archive/master.zip and install with this command:
sudo /usr/share/elasticsearch/bin/plugin install file:/home/dev/Downloads/elasticsearch-kopf-master.zip
Path maybe different depending on your environment.

To see all keys of Jsonobject use this
String JSON = "{\"LanguageLevels\":{\"1\":\"Pocz\\u0105tkuj\\u0105cy\",\"2\":\"\\u015arednioZaawansowany\",\"3\":\"Zaawansowany\",\"4\":\"Ekspert\"}}\n";
JSONObject obj = new JSONObject(JSON);
Iterator iterator = obj.keys();
String key = null;
while (iterator.hasNext()) {

None of the other answers worked for me on MacOS Sierra 10.12.4
Here is what I had to do:
git config --global --unset user.password
Then run your git command (ex. git push) and reenter your username and password.
Maximum time between connection request and a timeout error. When the client tries to make a connection, if the timeout wait limit is reached, it will stop trying and raise an error.
Thanks bhavya's solution.There have been two answers about swift, but those are not very intact. I have do that in the swift3.Below is the main code.
In AppDelegate.swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
// seclect the mainStoryBoard entry by whthere user is login.
let userDefaults = UserDefaults.standard
if let isLogin: Bool = userDefaults.value(forKey:Common.isLoginKey) as! Bool? {
if (!isLogin) {
self.window?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "LogIn")
}
}else {
self.window?.rootViewController = mainStoryboard.instantiateViewController(withIdentifier: "LogIn")
}
return true
}
In SignUpViewController.swift
@IBAction func userLogin(_ sender: UIButton) {
//handle your login work
UserDefaults.standard.setValue(true, forKey: Common.isLoginKey)
let delegateTemp = UIApplication.shared.delegate
delegateTemp?.window!?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "Main")
}
In logOutAction function
@IBAction func logOutAction(_ sender: UIButton) {
UserDefaults.standard.setValue(false, forKey: Common.isLoginKey)
UIApplication.shared.delegate?.window!?.rootViewController = UIStoryboard(name: "Main", bundle: nil).instantiateInitialViewController()
}
If you're using moment
then that's the single line code:
moment(date).format("DD/MM/YYYY").isValid()
try this code
you can not store mapper in NSUserDefault, you can only store NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary.
let myData = NSKeyedArchiver.archivedData(withRootObject: myJson)
UserDefaults.standard.set(myData, forKey: "userJson")
let recovedUserJsonData = UserDefaults.standard.object(forKey: "userJson")
let recovedUserJson = NSKeyedUnarchiver.unarchiveObject(with: recovedUserJsonData)

Today I was looking for this very solution and I tried PDFtoPrinter which I had an issue with (the PDFs I tried printing suggested they used incorrect paper size which hung the print job and nothing else printed until resolved). In my effort to find an alternative, I remembered GhostScript and utilities associated with it. I found GSView and it's associated program GSPrint (reference https://www.ghostscript.com/). Both these require GhostScript (https://www.ghostscript.com/) but when all the components are installed, GSPrint worked flawlessly and I was able to create a scheduled task that printed PDFs automatically overnight.
Given an instance of the struct, you set the values.
student thisStudent;
Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");
thisStudent.s_id = int.Parse(Console.ReadLine());
thisStudent.s_name = Console.ReadLine();
thisStudent.c_name = Console.ReadLine();
thisStudent.s_dob = Console.ReadLine();
Note this code is incredibly fragile, since we aren't checking the input from the user at all. And you aren't clear to the user that you expect each data point to be entered on a separate line.
Add this to your model:
def self.update_or_create_by(args, attributes)
obj = self.find_or_create_by(args)
obj.update(attributes)
return obj
end
With that, you can:
User.update_or_create_by({name: 'Joe'}, attributes)
Try this
data to load:
<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 4 5'><path fill='#343a40' d='M2 0L0 2h4zm0 5L0 3h4z'/></svg>
get a utf8 to base64 convertor and convert the "svg" string to:
PHN2ZyB4bWxucz0naHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmcnIHZpZXdCb3g9JzAgMCA0IDUn

On Windows you can try these steps:
/lib/security
with JRE (you can use a comand System.out.println(System.getProperty("java.home");
to find the folder with the current JRE). Make a backup of the file.THIS WORKS GREAT - I tested it so, please SET NAME for every object
give the name to the object upon creation
mesh.name = 'nameMeshObject';
and use this if you have to delete an object
delete3DOBJ('nameMeshObject');
function delete3DOBJ(objName){
var selectedObject = scene.getObjectByName(objName);
scene.remove( selectedObject );
animate();
}
If you are working on your own, and you want the closest thing to OOP as you would find in Java or C# or C++, see the javascript library, CrxOop. CrxOop provides syntax somewhat familiar to Java developers.
Just be careful, Java's OOP is not the same as that found in Javascript. To get the same behavior as in Java, use CrxOop's classes, not CrxOop's structures, and make sure all your methods are virtual. An example of the syntax is,
crx_registerClass("ExampleClass",
{
"VERBOSE": 1,
"public var publicVar": 5,
"private var privateVar": 7,
"public virtual function publicVirtualFunction": function(x)
{
this.publicVar1 = x;
console.log("publicVirtualFunction");
},
"private virtual function privatePureVirtualFunction": 0,
"protected virtual final function protectedVirtualFinalFunction": function()
{
console.log("protectedVirtualFinalFunction");
}
});
crx_registerClass("ExampleSubClass",
{
VERBOSE: 1,
EXTENDS: "ExampleClass",
"public var publicVar": 2,
"private virtual function privatePureVirtualFunction": function(x)
{
this.PARENT.CONSTRUCT(pA);
console.log("ExampleSubClass::privatePureVirtualFunction");
}
});
var gExampleSubClass = crx_new("ExampleSubClass", 4);
console.log(gExampleSubClass.publicVar);
console.log(gExampleSubClass.CAST("ExampleClass").publicVar);
The code is pure javascript, no transpiling. The example is taken from a number of examples from the official documentation.
We had exactly the same challenge some time ago. We wanted to go with CEF3 open source library which is WPF-based and supports .NET 3.5.
Firstly, the author of CEF himself listed binding for different languages here.
Secondly, we went ahead with open source .NET CEF3 binding which is called Xilium.CefGlue and had a good success with it. In cases where something is not working as you'd expect, author usually very responsive to the issues opened in build-in bitbucket tracker
So far it has served us well. Author updates his library to support latest CEF3 releases and bug fixes on regular bases.
The error comes when you try to call sum(x)
and x
is a factor.
What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)
simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:
family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))
For a detailed explanation of why the intermediate as.character
step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?
Set the value it will set it as selected option for dropdown:
$("#salesrep").val("Bruce Jones");
If it still not working:
This error might be because of an attribute left empty in the manifest file.
An example:
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:logo="@drawable/ic_actionbar"
android:supportsRtl="true"
android:fullBackupContent="">
...
</application>
The fullBackupContent
is empty in the above example.
When it's changed to android:fullBackupContent="true"
it will be fixed.
I think you have to write each object to an own File or you have to split the one when reading it. You may also try to serialize your list and retrieve that when deserializing.
Above example is not Co-related Sub-Query. It is Derived Table / Inline-View since i.e, a Sub-query within FROM Clause.
A Corelated Sub-query should refer its parent(main Query) Table in it. For example See find the Nth max salary by Co-related Sub-query:
SELECT Salary
FROM Employee E1
WHERE N-1 = (SELECT COUNT(*)
FROM Employee E2
WHERE E1.salary <E2.Salary)
Co-Related Vs Nested-SubQueries.
Technical difference between Normal Sub-query and Co-related sub-query are:
1. Looping: Co-related sub-query loop under main-query; whereas nested not; therefore co-related sub-query executes on each iteration of main query. Whereas in case of Nested-query; subquery executes first then outer query executes next. Hence, the maximum no. of executes are NXM for correlated subquery and N+M for subquery.
2. Dependency(Inner to Outer vs Outer to Inner): In the case of co-related subquery, inner query depends on outer query for processing whereas in normal sub-query, Outer query depends on inner query.
3.Performance: Using Co-related sub-query performance decreases, since, it performs NXM iterations instead of N+M iterations. ¨ Co-related Sub-query Execution.

I had this problem when tried to run different web-socket samples.
When pointing browser to 'http://localhost:8080/' I got this error, but pointing exactly to 'http://localhost:8080/index.html' gave no error since in 'index.html' all was fully ok - jquery was included before using $..
Somehow autoforwarding to index.html not fully worked
Curl can post binary data from a file so I have been using process substitution and taking advantage of file descriptors whenever I need to post something nasty with curl and still want access to the vars in the current shell. Something like:
curl "http://localhost:8080" \
-H "Accept: application/json" \
-H "Content-Type:application/json" \
--data @<(cat <<EOF
{
"me": "$USER",
"something": $(date +%s)
}
EOF
)
This winds up looking like --data @/dev/fd/<some number>
which just gets processed like a normal file. Anyway if you wanna see it work locally just run nc -l 8080
first and in a different shell fire off the above command. You will see something like:
POST / HTTP/1.1
Host: localhost:8080
User-Agent: curl/7.43.0
Accept: application/json
Content-Type:application/json
Content-Length: 43
{ "me": "username", "something": 1465057519 }
As you can see you can call subshells and whatnot as well as reference vars in the heredoc. Happy hacking hope this helps with the '"'"'""""'''""''
.
You can create Custom date picker, that is work for all api levels.
public class CustomDatePickerDialog extends DatePickerDialog {
int maxYear;
int maxMonth;
int maxDay;
public CustomDatePickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear, int dayOfMonth) {
super(context, callBack, year, monthOfYear, dayOfMonth);
}
public void setMaxDate(long maxDate) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
getDatePicker().setMaxDate(System.currentTimeMillis());
} else {
final Calendar c = Calendar.getInstance();
c.setTimeInMillis(maxDate);
maxYear = c.get(Calendar.YEAR);
maxMonth = c.get(Calendar.MONTH);
maxDay = c.get(Calendar.DAY_OF_MONTH);
}
}
@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
super.onDateChanged(view, year, monthOfYear, dayOfMonth);
} else {
if (year > maxYear)
view.updateDate(maxYear, maxMonth, maxDay);
if (monthOfYear > maxMonth && year == maxYear)
view.updateDate(maxYear, maxMonth, maxDay);
if (dayOfMonth > maxDay && year == maxYear && monthOfYear == maxMonth)
view.updateDate(maxYear, maxMonth, maxDay);
}
}
set max date
final CustomDatePickerDialog pickerDialog = new CustomDatePickerDialog(getActivity(),
myDateListener, year, month, day);
pickerDialog.setMaxDate(System.currentTimeMillis());
pickerDialog.show();
See JavaDoc:
month - the value used to set the MONTH calendar field. Month value is 0-based. e.g., 0 for January.
So, the month you set is the first month of next year.

I faced the issue and was able to resolve it by making sure that the data types were exactly matching .
I was using SequelPro for adding the constraint and it was making the primary key as unsigned by default .
It's hard to add something too such an elaborate answer. Though I feel we should mention identify
here, particularly because @Ben shows a lot of dendrogram examples.
d_dist <- dist(as.matrix(d)) # find distance matrix
plot(hclust(d_dist))
clusters <- identify(hclust(d_dist))
identify
lets you interactively choose clusters from an dendrogram and stores your choices to a list. Hit Esc to leave interactive mode and return to R console. Note, that the list contains the indices, not the rownames (as opposed to cutree
).
The parentheses are poorly placed.
You need to use:
doThrow(new Exception()).when(mockedObject).methodReturningVoid(...);
^
and NOT use:
doThrow(new Exception()).when(mockedObject.methodReturningVoid(...));
^
This is explained in the documentation
Is the Config/setup.php
file actually in /test/content/home/
or is in your document root? it is best to make all references relative to your document root.
include $_SERVER['DOCUMENT_ROOT'] . "Config/setup.php";
Your current code assumes that the location of setup.php
is in /text/content/home/Config/setup.php
, is this correct?

First, to make things more clear, here is a short overview of JSP syntax elements:
There are several mechanisms for reusing content in a JSP file.
The following 4 mechanisms to include content in JSP can be categorized as direct reuse:
(for the first 3 mechanisms quoting from "Head First Servlets and JSP")
1) The include directive:
<%@ include file="header.html" %>
Static: adds the content from the value of the file attribute to the current page at translation time. The directive was originally intended for static layout templates, like HTML headers.
2) The
<jsp:include>
standard action:<jsp:include page="header.jsp" />
Dynamic: adds the content from the value of the page attribute to the current page at request time. Was intended more for dynamic content coming from JSPs.
3) The
<c:import>
JSTL tag:<c:import url=”http://www.example.com/foo/bar.html” />
Dynamic: adds the content from the value of the URL attribute to the current page, at request time. It works a lot like
<jsp:include>
, but it’s more powerful and flexible: unlike the other two includes, the<c:import>
url can be from outside the web Container!4) Preludes and codas:
Static: preludes and codas can be applied only to the beginnings and ends of pages.
You can implicitly include preludes (also called headers) and codas (also called footers) for a group of JSP pages by adding<include-prelude>
and<include-coda>
elements respectively within a<jsp-property-group>
element in the Web application web.xml deployment descriptor. Read more here:
• Configuring Implicit Includes at the Beginning and End of JSPs
• Defining implicit includes
Tag File is an indirect method of content reuse, the way of encapsulating reusable content. A Tag File is a source file that contains a fragment of JSP code that is reusable as a custom tag.
The PURPOSE of includes and Tag Files is different.
Tag file (a concept introduced with JSP 2.0) is one of the options for creating custom tags. It's a faster and easier way to build custom tags. Custom tags, also known as tag extensions, are JSP elements that allow custom logic and output provided by other Java components to be inserted into JSP pages. The logic provided through a custom tag is implemented by a Java object known as a tag handler.
Some examples of tasks that can be performed by custom tags include operating on implicit objects, processing forms, accessing databases and other enterprise services such as email and directories, and implementing flow control.
Maybe in your example (in your "Edit" paragraph), there is no difference between using direct include and a Tag File. But custom tags have a rich set of features. They can
Be customized by means of attributes passed from the calling page.
Pass variables back to the calling page.
Access all the objects available to JSP pages.
Communicate with each other. You can create and initialize a JavaBeans component, create a public EL variable that refers to that bean in one tag, and then use the bean in another tag.
Be nested within one another and communicate by means of private variables.
Also read this from "Pro JSP 2": Understanding JSP Custom Tags.
Difference between include directive and include action in JSP
Very informative and easy to understand tutorial from coreservlet.com with beautiful
explanations that include <jsp:include> VS. <%@ include %>
comparison table:
Including Files and Applets in JSP
Pages
Another nice tutorial from coreservlets.com related to tag libraries and
tag files:
Creating Custom JSP Tag Libraries: The
Basics
The official Java EE 5 Tutorial with examples:
Encapsulating Reusable Content
Using Tag
Files.
This page from the official Java EE 5 tutorial should give you even
more understanding:
Reusing Content in JSP
Pages.
This excerpt from the book "Pro JSP 2" also discuses why do you need
a Tag File instead of using static include:
Reusing Content with Tag
Files
Very useful guide right from the Oracle documentation:
Static Includes Versus Dynamic Includes
Use the right tools for each task.
Use Tag Files as a quick and easy way of creating custom tags that can help you encapsulate reusable content.
As for the including content in JSP (quote from here):
- Use the include directive if the file changes rarely. It’s the fastest mechanism. If your container doesn’t automatically detect changes, you can force the changes to take effect by deleting the main page class file.
- Use the include action only for content that changes often, and if which page to include cannot be decided until the main page is requested.
Natively WebAPI doesn't support binding of multiple POST parameters. As Colin points out there are a number of limitations that are outlined in my blog post he references.
There's a workaround by creating a custom parameter binder. The code to do this is ugly and convoluted, but I've posted code along with a detailed explanation on my blog, ready to be plugged into a project here:
This is what I recently did for my Data Visualization Application which has a 2008 SQL Database. In this example I am recieving a list returned from a stored procedure:
public List<CumulativeInstrumentsDataRow> GetCumulativeInstrumentLogs(RunLogFilter filter)
{
EFDbContext db = new EFDbContext();
if (filter.SystemFullName == string.Empty)
{
filter.SystemFullName = null;
}
if (filter.Reconciled == null)
{
filter.Reconciled = 1;
}
string sql = GetRunLogFilterSQLString("[dbo].[rm_sp_GetCumulativeInstrumentLogs]", filter);
return db.Database.SqlQuery<CumulativeInstrumentsDataRow>(sql).ToList();
}
And then this extension method for some formatting in my case:
public string GetRunLogFilterSQLString(string procedureName, RunLogFilter filter)
{
return string.Format("EXEC {0} {1},{2}, {3}, {4}", procedureName, filter.SystemFullName == null ? "null" : "\'" + filter.SystemFullName + "\'", filter.MinimumDate == null ? "null" : "\'" + filter.MinimumDate.Value + "\'", filter.MaximumDate == null ? "null" : "\'" + filter.MaximumDate.Value + "\'", +filter.Reconciled == null ? "null" : "\'" + filter.Reconciled + "\'");
}
This is an easy way for any format. Just change it to required format string
XMLGregorianCalendar gregFmt = DatatypeFactory.newInstance().newXMLGregorianCalendar(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss").format(new Date()));
System.out.println(gregFmt);
try to add ojdbc6.jar through the server lib "C:\apache-tomcat-7.0.47\lib",
Then restart the server in eclipse.
"I tried to figure out, why exactly we need Observer and Observable"
As previous answers already stated, they provide means of subscribing an observer to receive automatic notifications of an observable.
One example application where this may be useful is in data binding, let's say you have some UI that edits some data, and you want the UI to react when the data is updated, you can make your data observable, and subscribe your UI components to the data
Knockout.js is a MVVM javascript framework that has a great getting started tutorial, to see more observables in action I really recommend going through the tutorial. http://learn.knockoutjs.com/
I also found this article in Visual Studio 2008 start page (The Observer Pattern is the foundation of Model View Controller (MVC) development) http://visualstudiomagazine.com/articles/2013/08/14/the-observer-pattern-in-net.aspx

You can't set CURRENT_TIMESTAMP as default value with DATETIME.
But you can do it with TIMESTAMP.
See the difference here.
Words from this blog
The DEFAULT value clause in a data type specification indicates a default value for a column. With one exception, the default value must be a constant; it cannot be a function or an expression.
This means, for example, that you cannot set the default for a date column to be the value of a function such as NOW() or CURRENT_DATE.
The exception is that you can specify CURRENT_TIMESTAMP as the default for a TIMESTAMP column.
// re initialze datepicker
$(".bootstrap-datepicker").bsdatepicker({
format: "yyyy-mm-dd",
autoclose: true,
}).on('changeDate', function (ev) {
$(this).bsdatepicker('hide');
});
//
$(".dropdown-menu").css({'z-index':'1100'});
TypeScript have a way of validating the type of a variable in runtime. You can add a validating function that returns a type predicate. So you can call this function inside an if statement, and be sure that all the code inside that block is safe to use as the type you think it is.
Example from the TypeScript docs:
function isFish(pet: Fish | Bird): pet is Fish {
return (<Fish>pet).swim !== undefined;
}
// Both calls to 'swim' and 'fly' are now okay.
if (isFish(pet)) {
pet.swim();
}
else {
pet.fly();
}

I have found one solution to this, not saying it's the best one, but it feels clean to me and doesn't require any major changes to my code. My code looked similar to yours until I realized it didn't work.
My Base Class
public class MyBaseClass
{
public string BaseProperty1 { get; set; }
public string BaseProperty2 { get; set; }
public string BaseProperty3 { get; set; }
public string BaseProperty4 { get; set; }
public string BaseProperty5 { get; set; }
}
My Derived Class
public class MyDerivedClass : MyBaseClass
{
public string DerivedProperty1 { get; set; }
public string DerivedProperty2 { get; set; }
public string DerivedProperty3 { get; set; }
}
Previous method to get a populated base class
public MyBaseClass GetPopulatedBaseClass()
{
var myBaseClass = new MyBaseClass();
myBaseClass.BaseProperty1 = "Something"
myBaseClass.BaseProperty2 = "Something else"
myBaseClass.BaseProperty3 = "Something more"
//etc...
return myBaseClass;
}
Before I was trying this, which gave me a unable to cast error
public MyDerivedClass GetPopulatedDerivedClass()
{
var newDerivedClass = (MyDerivedClass)GetPopulatedBaseClass();
newDerivedClass.UniqueProperty1 = "Some One";
newDerivedClass.UniqueProperty2 = "Some Thing";
newDerivedClass.UniqueProperty3 = "Some Thing Else";
return newDerivedClass;
}
I changed my code as follows bellow and it seems to work and makes more sense now:
Old
public MyBaseClass GetPopulatedBaseClass()
{
var myBaseClass = new MyBaseClass();
myBaseClass.BaseProperty1 = "Something"
myBaseClass.BaseProperty2 = "Something else"
myBaseClass.BaseProperty3 = "Something more"
//etc...
return myBaseClass;
}
New
public void FillBaseClass(MyBaseClass myBaseClass)
{
myBaseClass.BaseProperty1 = "Something"
myBaseClass.BaseProperty2 = "Something else"

While you can call the parent method by the prototype of the parent, you will need to pass the current child instance for using call
, apply
, or bind
method. The bind
method will create a new function so I doesn't recommend that if you care for performance except it only called once.
As an alternative you can replace the child method and put the parent method on the instance while calling the original child method.
function proxy(context, parent){
var proto = parent.prototype;
var list = Object.getOwnPropertyNames(proto);
for(var i=0; i < list.length; i++){
var key = list[i];
// Create only when child have similar method name
if(context[key] !== proto[key]){
let currentMethod = context[key];
let parentMethod = proto[key];
context[key] = function(){
context.super = parentMethod;
return currentMethod.apply(context, arguments);
}
}
}
}
// ========= The usage would be like this ==========
class Parent {
first = "Home";
constructor(){
console.log('Parent created');
}
add(arg){
return this.first + ", Parent "+arg;
}
}
class Child extends Parent{
constructor(b){
super();
proxy(this, Parent);
console.log('Child created');
}
// Comment this to call method from parent only
add(arg){
return super.add(arg) + ", Child "+arg;
}
}
var family = new Child();
console.log(family.add('B'));

Nouns.h

, but it needs to. You need to add
#include <string>
at the top of that file, otherwise the compiler doesn't know what std::string
is when it is encountered for the first time.
Checking Count() before the WHERE clause solved my problem. It is cheaper than ToList()
if (authUserList != null && _list.Count() > 0)
_list = _list.Where(l => authUserList.Contains(l.CreateUserId));
Open the svg using Inkscape.
Inkscape is a svg editor it is a bit like Illustrator but as it is built specifically for svg it handles it way better. It is a free software and it's available @ https://inkscape.org/en/

I had the same problem, and I found the solution in this post of Sam Goddard,
The solution if to defined the call to the font twice. First as it is recommended, to be used for all the browsers, and after a particular call only for Chrome with a special media query:
@font-face {
font-family: 'chunk-webfont';
src: url('../../includes/fonts/chunk-webfont.eot');
src: url('../../includes/fonts/chunk-webfont.eot?#iefix') format('eot'),
url('../../includes/fonts/chunk-webfont.woff') format('woff'),
url('../../includes/fonts/chunk-webfont.ttf') format('truetype'),
url('../../includes/fonts/chunk-webfont.svg') format('svg');
font-weight: normal;
font-style: normal;
}
@media screen and (-webkit-min-device-pixel-ratio:0) {
@font-face {
font-family: 'chunk-webfont';
src: url('../../includes/fonts/chunk-webfont.svg') format('svg');
}
}
With this method the font will render good in all browsers. The only negative point that I found is that the font file is also downloaded twice.

I use a personnal blend of the phantomjs waitfor.js
example.
This is my main.js
file:
'use strict';
var wasSuccessful = phantom.injectJs('./lib/waitFor.js');
var page = require('webpage').create();
page.open('http://foo.com', function(status) {
if (status === 'success') {
page.includeJs('https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js', function() {
waitFor(function() {
return page.evaluate(function() {
if ('complete' === document.readyState) {
return true;
}
return false;
});
}, function() {
var fooText = page.evaluate(function() {
return $('#foo').text();
});
phantom.exit();
});
});
} else {
console.log('error');
phantom.exit(1);
}
});
And the lib/waitFor.js
file (which is just a copy and paste of the waifFor()
function from the phantomjs waitfor.js
example):
function waitFor(testFx, onReady, timeOutMillis) {
var maxtimeOutMillis = timeOutMillis ? timeOutMillis : 3000, //< Default Max Timout is 3s
start = new Date().getTime(),
condition = false,
interval = setInterval(function() {
if ( (new Date().getTime() - start < maxtimeOutMillis) && !condition ) {
// If not time-out yet and condition not yet fulfilled
condition = (typeof(testFx) === "string" ? eval(testFx) : testFx()); //< defensive code
} else {
if(!condition) {
// If condition still not fulfilled (timeout but condition is 'false')
console.log("'waitFor()' timeout");
phantom.exit(1);
} else {
// Condition fulfilled (timeout and/or condition is 'true')
// console.log("'waitFor()' finished in " + (new Date().getTime() - start) + "ms.");
typeof(onReady) === "string" ? eval(onReady) : onReady(); //< Do what it's supposed to do once the condi>
clearInterval(interval); //< Stop this interval
}
}
}, 250); //< repeat check every 250ms
}
This method is not asynchronous but at least am I assured that all the resources were loaded before I try using them.
Honestly I am not sure if I really understand your question :P I will try to clarify as much as I can, from what I get from your original question:
First, in most case, you should NOT have any concern on Spring. You rarely need to have spring involved in writing your unit test. In normal case, you only need to instantiate the system under test (SUT, the target to be tested) in your unit test, and inject dependencies of SUT in the test too. The dependencies are usually a mock/stub.
Your original suggested way, and example 2, 3 is precisely doing what I am describing above.
In some rare case (like, integration tests, or some special unit tests), you need to create a Spring app context, and get your SUT from the app context. In such case, I believe you can:
1) Create your SUT in spring app ctx, get reference to it, and inject mocks to it
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("test-app-ctx.xml")
public class FooTest {
@Autowired
@InjectMocks
TestTarget sut;
@Mock
Foo mockFoo;
@Before
/* Initialized mocks */
public void setup() {
MockitoAnnotations.initMocks(this);
}
@Test
public void someTest() {
// ....
}
}
or
2) follow the way described in your link Spring Integration Tests, Creating Mock Objects. This approach is to create mocks in Spring's app context, and you can get the mock object from the app ctx to do your stubbing/verification:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("test-app-ctx.xml")
public class FooTest {
@Autowired
TestTarget sut;
@Autowired
Foo mockFoo;
@Test
public void someTest() {
// ....
}
}
Both ways should work. The main difference is the former case will have the dependencies injected after going through spring's lifecycle etc. (e.g. bean initialization), while the latter case is injected beforehands. For example, if your SUT implements spring's InitializingBean, and the initialization routine involves the dependencies, you will see the difference between these two approach. I believe there is no right or wrong for these 2 approaches, as long as you know what you are doing.
Just a supplement, @Mock, @Inject, MocktoJunitRunner etc are all unnecessary in using Mockito. They are just utilities to save you typing the Mockito.mock(Foo.class) and bunch of setter invocations.
Hibernate is not going to make it easy for you to do what you are trying to do. From the Hibernate documentation:
Note that when using referencedColumnName to a non primary key column, the associated class has to be Serializable. Also note that the referencedColumnName to a non primary key column has to be mapped to a property having a single column (other cases might not work). (emphasis added)
So if you are unwilling to make AnEmbeddableObject
the Identifier for Bar then Hibernate is not going to lazily, automatically retrieve Bar for you. You can, of course, still use HQL to write queries that join on AnEmbeddableObject
, but you lose automatic fetching and life cycle maintenance if you insist on using a multi-column non-primary key for Bar.
The exception message clearly speaks that the class versions, which would include the class meta data as well, has changed over time. In other words, the class structure during serialization is not the same during de-serialization. This is what is most probably "going on".
I think you are working in sudo mode.Please checkout to the user mode and try again
You are trying to load a XIB named DetailViewController
, but no such XIB exists or it's not member of your current target.
This is happen due to the id(auto increment filed missing). If you edit it in a text editor by adding a comma for the ID field this will be solved.
Simply put:
SELECT *
FROM TABLE_NAME
WHERE
dob > '1/21/2012'
Where 1/21/2012 is the date and you want all data, including that date.
SELECT *
FROM TABLE_NAME
WHERE
dob BETWEEN '1/21/2012' AND '2/22/2012'
Use a between if you're selecting time between two dates
Update PHP 7.4
Curly brace access syntax is deprecated since PHP 7.4
Update 2019
Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.
Simply iterate its using {}
Example:
$videos{0}->id
This way your object is not destroyed and you can easily iterate through object.
For PHP 5.6 and below use this
$videos{0}['id']
Both array() and the stdClass objects can be accessed using the
current()
key()
next()
prev()
reset()
end()
functions.
So, if your object looks like
object(stdClass)#19 (3) {
[0]=>
object(stdClass)#20 (22) {
["id"]=>
string(1) "123"
etc...
Then you can just do;
$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object
If you need the key for some reason, you can do;
reset($obj); //Ensure that we're at the first element
$key = key($obj);
Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4
2022 Update:
After PHP 7.4, using current()
, end()
, etc functions on objects is deprecated.
In newer versions of PHP, use the ArrayIterator class:
$objIterator = new ArrayIterator($obj);
$id = $objIterator->current()->id; // Gets the 'id' attr of the first entry in the object
$key = $objIterator->key(); // and gets the key
Just check tsnnames.ora and listener.ora files. It should not have localhost as a server. change it to hostname.
Like in tnsnames.ora
LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
Replace localhost by hostname.
Look for books by Ted Padova. Over the years, he has written a series of books called The Acrobat PDF {5,6,7,8,9...} Bible. They contain chapter(s) on JavaScript in PDF files. They are not as comprehensive as the reference documentation listed here, but in the books there are some realistic use-cases discussed in context.
There was also a talk on hacking PDF files by a computer scientist, given at a conference in 2010. The link on the talk's announcement-page to the slides is dead, but Google is your friend-. The talk is not exclusively on JavaScript, though. YouTube video - JavaScript starts at 06:00.
Keep in mind that it's the user that is running the oracle database that must have write permissions to the /defaultdir directory, not the user logged into oracle. Typically you're running the database as the user "Oracle". It's not the same user (necessarily) that you created the external table with.
Check your directory permissions, too.

In iPhone iOS6 and from Android ICS onwards, HTML5 has the following tag which allows you to take pictures from your device:
<input type="file" accept="image/*" capture="camera">
Capture
can take values like camera, camcorder and audio.
I think this tag will definitely not work in iOS5, not sure about it.
I know I'm late to the party, but I needed something similar that the above answers didn't help.
I was using Angular's $watch function to detect changes in a variable. Not only did I need to know whether a property had changed on the variable, but I also wanted to make sure that the property that changed was not a temporary, calculated field. In other words, I wanted to ignore certain properties.
Here's the code: https://jsfiddle.net/rv01x6jo/
Here's how to use it:
// To only return the difference
var difference = diff(newValue, oldValue);
// To exclude certain properties
var difference = diff(newValue, oldValue, [newValue.prop1, newValue.prop2, newValue.prop3]);
Hope this helps someone.
For me, I forgot to add the default serial id.
private static final long serialVersionUID = 1L;
I arrived at this question looking for a way to stream an open ended list of objects onto a System.IO.Stream
and read them off the other end, without buffering the entire list before sending. (Specifically I'm streaming persisted objects from MongoDB over Web API.)
@Paul Tyng and @Rivers did an excellent job answering the original question, and I used their answers to build a proof of concept for my problem. I decided to post my test console app here in case anyone else is facing the same issue.
using System;
using System.Diagnostics;
using System.IO;
using System.IO.Pipes;
using System.Threading;
using System.Threading.Tasks;
using Newtonsoft.Json;
namespace TestJsonStream {
class Program {
static void Main(string[] args) {
using(var writeStream = new AnonymousPipeServerStream(PipeDirection.Out, HandleInheritability.None)) {
string pipeHandle = writeStream.GetClientHandleAsString();
var writeTask = Task.Run(() => {
using(var sw = new StreamWriter(writeStream))
using(var writer = new JsonTextWriter(sw)) {
var ser = new JsonSerializer();
writer.WriteStartArray();
for(int i = 0; i < 25; i++) {
ser.Serialize(writer, new DataItem { Item = i });
writer.Flush();
Thread.Sleep(500);
}
writer.WriteEnd();
writer.Flush();
}
});
var readTask = Task.Run(() => {
var sw = new Stopwatch();
sw.Start();
using(var readStream = new AnonymousPipeClientStream(pipeHandle))
using(var sr = new StreamReader(readStream))
using(var reader = new JsonTextReader(sr)) {
var ser = new JsonSerializer();
if(!reader.Read() || reader.TokenType != JsonToken.StartArray) {
throw new Exception("Expected start of array");
}
while(reader.Read()) {
if(reader.TokenType == JsonToken.EndArray) break;
var item = ser.Deserialize<DataItem>(reader);
Console.WriteLine("[{0}] Received item: {1}", sw.Elapsed, item);
}
}
});
Task.WaitAll(writeTask, readTask);
writeStream.DisposeLocalCopyOfClientHandle();
}
}
class DataItem {
public int Item { get; set; }
public override string ToString() {
return string.Format("{{ Item = {0} }}", Item);
}
}
}
}
Note that you may receive an exception when the AnonymousPipeServerStream
is disposed, I ignored this as it isn't relevant to the problem at hand.
You'll have to use the "userInfo" variant and pass a NSDictionary object that contains the messageTotal integer:
NSDictionary* userInfo = @{@"total": @(messageTotal)};
NSNotificationCenter* nc = [NSNotificationCenter defaultCenter];
[nc postNotificationName:@"eRXReceived" object:self userInfo:userInfo];
On the receiving end you can access the userInfo dictionary as follows:
-(void) receiveTestNotification:(NSNotification*)notification
{
if ([notification.name isEqualToString:@"TestNotification"])
{
NSDictionary* userInfo = notification.userInfo;
NSNumber* total = (NSNumber*)userInfo[@"total"];
NSLog (@"Successfully received test notification! %i", total.intValue);
}
}
By default, Spring beans are singletons. The problem arises when we try to wire beans of different scopes. For example, a prototype bean into a singleton. This is known as the scoped bean injection problem.
Another way to solve the problem is method injection with the @Lookup annotation.
Here is a nice article on this issue of injecting prototype beans into a singleton instance with multiple solutions.
https://www.baeldung.com/spring-inject-prototype-bean-into-singleton
I realize this is a rather late post but still a possible solution for the OP. I use IE9 on Win 7 and have been having Adobe Reader's grey screen issues for several months when trying to open pdf bank and credit card statements online. I could open everything in Firefox or Opera but not IE. I finally tried PDF-Viewer, set it as the default pdf viewer in its preferences and no more problems. I'm sure there are other free viewers out there, like Foxit, PDF-Xchange, etc., that will give better results than Reader with less headaches. Adobe is like some of the other big companies that develop software on a take it or leave it basis ... so I left it.
void 0
returns undefined and can not be overwritten while undefined
can be overwritten.
var undefined = "HAHA";
With Mac OS X and the more recent versions of Acrobat Pro, the PDF printer option does not work. What does work is doing basically the same thing in Preview App. Open the multi page file in Preview, select File>Print. In the Print dialog set your sheet size as if you are using a printer. You may want to select "Auto Rotate", "Scale to Fit" and "Print Entire Image". Then in the lower left corner is the drop button "PDF" and in that menu select "Save as PDF". Give it a new file name, click Save and then you can open the resulting file in whatever PDF app you want and the sheet sizes are the same.
Try wrapping your dates in single quotes, like this:
'15-6-2005'
It should be able to parse the date this way.
In my case (Spring 3.2.4 and Jackson 2.3.1), XML configuration for custom serializer:
<mvc:annotation-driven>
<mvc:message-converters register-defaults="false">
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="objectMapper">
<bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
<property name="serializers">
<array>
<bean class="com.example.business.serializer.json.CustomObjectSerializer"/>
</array>
</property>
</bean>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
was in unexplained way overwritten back to default by something.
This worked for me:
@JsonSerialize(using = CustomObjectSerializer.class)
public class CustomObject {
private Long value;
public Long getValue() {
return value;
}
public void setValue(Long value) {
this.value = value;
}
}
public class CustomObjectSerializer extends JsonSerializer<CustomObject> {
@Override
public void serialize(CustomObject value, JsonGenerator jgen,
SerializerProvider provider) throws IOException,JsonProcessingException {
jgen.writeStartObject();
jgen.writeNumberField("y", value.getValue());
jgen.writeEndObject();
}
@Override
public Class<CustomObject> handledType() {
return CustomObject.class;
}
}
No XML configuration (<mvc:message-converters>(...)</mvc:message-converters>
) is needed in my solution.
You're calling e.nextElement()
twice inside your loop when you're only guaranteed that you can call it once without an exception. Rewrite the loop like so:
while(e.hasMoreElements()){
String param = e.nextElement();
System.out.println(param);
}
In my case I'm running MacOs High Sierra with Java 1.6. The cacert file is in a different location than referenced above in Gabe Martin-Dempesy's answer. The cacert file was also already linked to another location (/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib/security/cacerts).
Using FireFox, I exported the certificate from the web site in question to a local file called "exportedCertFile.crt". From there, I used keytool to move the certificate into the cacert file. This fixed the problem.
bash-3.2# cd /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/
bash-3.2# keytool -importcert -file ~/exportedCertFile.crt -alias example -keystore cacerts -storepass changeit
Generally if something works on various computers but fails on only one computer, then there's something wrong with that computer. Here are a few things to check:
(1) Are you running the same stuff on that computer -- OS including patches, etc.
(2) Does the computer report problems? Where to look depends on the OS, but it looks like you're using linux, so check syslog
(3) Run hardware diagnostics, e.g. the ones recommended here. Start with memory and disk checks in particular.
If you can't turn up any issues, then search for a similar issue in the bug parade for whichever VM you're using. Unfortunately if you're already on the latest version of the VM, then you won't necessarily find a fix.
Finally, one more option is simply to try another VM -- e.g. OpenJDK or JRockit, instead of Oracle's standard.
Take a look at the Clay library:
It provides something similar to the ExpandoObject but with a bunch of extra features. Here is blog post explaining how to use it:
http://weblogs.asp.net/bleroy/archive/2010/08/18/clay-malleable-c-dynamic-objects-part-2.aspx
(be sure to read the IPerson interface example)
What do you actually want to achieve? What your code does is it tries to connect to a server located at 192.168.1.104:4000
. Is this the address of a server that sends the messages (because this looks like a client-side code)? If I run fake server locally:
$ nc -l 4000
...and change socket address to localhost:4000
, it will work and try to read something from nc
-created server.
ServerSocket
and listen on it:ServerSocket serverSocket = new ServerSocket(4000);
Socket socket = serverSocket.accept();
The second line will block until some other piece of software connects to your machine on port 4000. Then you can read from the returned socket. Look at this tutorial, this is actually a very broad topic (threading, protocols...)
For those of you rookies out there who may throw a SQL error when connecting to the DB from another machine(For example, at form load), you will find that when you first setup a datatable in C# which points to a SQL server database that it will setup a connection like this:
this.Table_nameTableAdapter.Fill(this.DatabaseNameDataSet.Table_name);
You may need to remove this line and replace it with something else like a traditional connection string as mentioned on MSDN, etc.
If you just want to display it when you get a response add this to your loadpage()
function loadpage(page_request, containerid){
if (page_request.readyState == 4 && page_request.status==200) {
var container = document.getElementById(containerid);
container.innerHTML=page_request.responseText;
container.style.visibility = 'visible';
// or
container.style.display = 'block';
}
but this depend entirely on how you hid the div in the first place
You can use this:
response.sendRedirect(String.format("%s%s", request.getContextPath(), "/views/equipment/createEquipment.jsp"));
The last part is your path in your web-app
MonoTouch and MonoDroid but what will happen to that part of Attachmate now is anybody's guess. Of course even with the mono solutions you're still creating non cross platform views but the idea being the reuse of business logic.
Keep an eye on http://www.xamarin.com/ it will be interesting to see what they come up with.
If you just want to print user name on the pages, maybe you'll like this solution. It's free from object castings and works without Spring Security too:
@RequestMapping(value = "/index.html", method = RequestMethod.GET)
public ModelAndView indexView(HttpServletRequest request) {
ModelAndView mv = new ModelAndView("index");
String userName = "not logged in"; // Any default user name
Principal principal = request.getUserPrincipal();
if (principal != null) {
userName = principal.getName();
}
mv.addObject("username", userName);
// By adding a little code (same way) you can check if user has any
// roles you need, for example:
boolean fAdmin = request.isUserInRole("ROLE_ADMIN");
mv.addObject("isAdmin", fAdmin);
return mv;
}
Note "HttpServletRequest request" parameter added.
Works fine because Spring injects it's own objects (wrappers) for HttpServletRequest, Principal etc., so you can use standard java methods to retrieve user information.
Request.Form is a NameValueCollection. In NameValueCollection you can find the GetAllValues() method.
By the way the LINQ method also works.
Although a late reply, but I'm posting the answer because I suffered the same pain. I've created a new GitHub project just for that, as of now, it supports Bulk insert/update/delete for Sql server transparently using SqlBulkCopy.
https://github.com/MHanafy/EntityExtensions
There're other goodies as well, and hopefully, It will be extended to do more down the track.
Using it is as simple as
var insertsAndupdates = new List<object>();
var deletes = new List<object>();
context.BulkUpdate(insertsAndupdates, deletes);
Hope it helps!
I faced this problem today and resolved it by checking the mapping class. I had a class which had 5 properties to which 5 columns returned from stored procedure were being mapped. Those properties were non-nullable and due to which i was getting the error. I made them nullable and the issue resolved.
public int? Pause { get; set; }
public int? Delay { get; set; }
public int? Transition { get; set; }
public int? TransitionTime { get; set; }
public int? TransitionResolution { get; set; }
Added "?" with data type to made them nullable.
Secondly i also added isNull check in the stored procedure as well as follows:
isnull(co_pivot.Pause, 0) as Pause,
isnull(co_pivot.Delay, 0) as Delay,
isnull(co_pivot.Transition, 0) as Transition,
isnull(co_pivot.TransitionTime, 0) as TransitionTime,
isnull(co_pivot.TransitionResolution, 0) as TransitionResolution
Hope this helps someone.
Once you have the source trees, e.g.

You don't need a FK, you can join arbitrary columns.
But having a foreign key ensures that the join will actually succeed in finding something.
Foreign key give you certain guarantees that would be extremely difficult and error prone to implement otherwise.
For example, if you don't have a foreign key, you might insert a detail record in the system and just after you checked that the matching master record is present somebody else deletes it. So in order to prevent this you need to lock the master table, when ever you modify the detail table (and vice versa). If you don't need/want that guarantee, screw the FKs.
Depending on your RDBMS a foreign key also might improve performance of select (but also degrades performance of updates, inserts and deletes)
I found eot
file should be put beyond ttf
. If it's under ttf
, thought the font shows correctly, IE9 will still throw an error.
Recommend:
@font-face {
font-family: 'Font-Name';
src: url('../fonts/Font-Name.eot?#iefix') format('embedded-opentype');
src: url('../fonts/Font-Name.ttf') format('truetype');
}
Not Recommend:
@font-face {
font-family: 'Font-Name';
src: url('../fonts/Font-Name.ttf') format('truetype');
src: url('../fonts/Font-Name.eot?#iefix') format('embedded-opentype');
}
I know this is very late but for future readers ...
Beware of the approaches above that are based only on the name of the class of A, B, C ... :
Unless you can guarantee that A, B, C ... (all subclasses or implementers of Base) are final then subclasses of A, B, C ... will not be dealt with.
Even though the if, elseif, elseif .. approach is slower for large number of subclasses/implementers, it is more accurate.
As @Agam said,
You need this statement in your driver file:
from AthleteList import AtheleteList
Could you post the exact query? The ExecuteNonQuery
method returns the @@ROWCOUNT
Sql Server variable what ever it is after the last query has executed is what the ExecuteNonQuery
method returns.
Maybe better to make an anchor with DeleteJob url instead of button?
<a href="<%=Url.Action("DeleteJob", "YourController", new {selectedObject="someObject"})%>" onclick="return DeleteJob()">Löschen</a>
and use your javascript you wrote already:
function DeleteJob() {
if (confirm("Do you really want to delete selected job/s?"))
return true;
else
return false;
}
So if function return true - you will be redirected. If function return false - you still stay on the page.
The method viewWillAppear
should be taken in the context of what is going on in your own application, and not in the context of your application being placed in the foreground when you switch back to it from another app.
In other words, if someone looks at another application or takes a phone call, then switches back to your app which was earlier on backgrounded, your UIViewController which was already visible when you left your app 'doesn't care' so to speak -- as far as it is concerned, it's never disappeared and it's still visible -- and so viewWillAppear
isn't called.
I recommend against calling the viewWillAppear
yourself -- it has a specific meaning which you shouldn't subvert! A refactoring you can do to achieve the same effect might be as follows:
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[self doMyLayoutStuff:self];
}
- (void)doMyLayoutStuff:(id)sender {
// stuff
}
Then also you trigger doMyLayoutStuff
from the appropriate notification:
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(doMyLayoutStuff:) name:UIApplicationDidChangeStatusBarFrameNotification object:self];
There's no out of the box way to tell which is the 'current' UIViewController by the way. But you can find ways around that, e.g. there are delegate methods of UINavigationController for finding out when a UIViewController is presented therein. You could use such a thing to track the latest UIViewController which has been presented.
Update
If you layout out UIs with the appropriate autoresizing masks on the various bits, sometimes you don't even need to deal with the 'manual' laying out of your UI - it just gets dealt with...
The problem is that 2011-01-31 really is 2011-01-31 00:00:00. That is the beginning of the day. Everything during the day is not included.
I ended up doing the following and it works.
public static string Serialize(object obj)
{
using (MemoryStream memoryStream = new MemoryStream())
{
DataContractSerializer serializer = new DataContractSerializer(obj.GetType());
serializer.WriteObject(memoryStream, obj);
return Encoding.UTF8.GetString(memoryStream.ToArray());
}
}
public static object Deserialize(string xml, Type toType)
{
using (MemoryStream memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(xml)))
{
XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(memoryStream, Encoding.UTF8, new XmlDictionaryReaderQuotas(), null);
DataContractSerializer serializer = new DataContractSerializer(toType);
return serializer.ReadObject(reader);
}
}
It seems that the major problem was in the Serialize function when calling stream.GetBuffer(). Calling stream.ToArray() appears to work.
You can also use fpdf class available at: http://www.fpdf.org. It gives options for both outputting to a file and displaying on browser.
They both track your changes to the collection, just call the SaveChanges() method that should update the DB.
It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.
The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:
You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:
Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:
#toolbar=0&navpanes=0
So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.
string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);

For sending data to a service you can use:
Intent intent = new Intent(getApplicationContext(), YourService.class);
intent.putExtra("SomeData","ItValue");
startService(intent);
And after in service in onStartCommand() get data from intent.
For sending data or event from a service to an application (for one or more activities):
private void sendBroadcastMessage(String intentFilterName, int arg1, String extraKey) {
Intent intent = new Intent(intentFilterName);
if (arg1 != -1 && extraKey != null) {
intent.putExtra(extraKey, arg1);
}
sendBroadcast(intent);
}
This method is calling from your service. You can simply send data for your Activity.
private void someTaskInYourService(){
//For example you downloading from server 1000 files
for(int i = 0; i < 1000; i++) {
Thread.sleep(5000) // 5 seconds. Catch in try-catch block
sendBroadCastMessage(Events.UPDATE_DOWNLOADING_PROGRESSBAR, i,0,"up_download_progress");
}
For receiving an event with data, create and register method registerBroadcastReceivers() in your activity:
private void registerBroadcastReceivers(){
broadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
int arg1 = intent.getIntExtra("up_download_progress",0);
progressBar.setProgress(arg1);
}
};
IntentFilter progressfilter = new IntentFilter(Events.UPDATE_DOWNLOADING_PROGRESS);
registerReceiver(broadcastReceiver,progressfilter);
For sending more data, you can modify method sendBroadcastMessage();
. Remember: you must register broadcasts in onResume() & unregister in onStop() methods!
UPDATE
Please don't use my type of communication between Activity & Service. This is the wrong way. For a better experience please use special libs, such us:
1) EventBus from greenrobot
2) Otto from Square Inc
P.S. I'm only using EventBus from greenrobot in my projects,
You mean something like this?

preparedStatement.setXXX(index, VALUE);
preparedStatement.executeUpdate();
ResultSet rs = preparedStatement.getGeneratedKeys();
if (rs.next()) {
key = rs.getLong(1);
}
I solved this problem following vestigal's tips here:
Can I set an unlimited length for maxJsonLength in web.config?
When I needed to post a large json to an action in a controller, I would get the famous "Error during deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.\r\nParameter name: input value provider".
What I did is create a new ValueProviderFactory, LargeJsonValueProviderFactory, and set the MaxJsonLength = Int32.MaxValue in the GetDeserializedObject method
public sealed class LargeJsonValueProviderFactory : ValueProviderFactory
{
private static void AddToBackingStore(LargeJsonValueProviderFactory.EntryLimitedDictionary backingStore, string prefix, object value)
{
IDictionary<string, object> dictionary = value as IDictionary<string, object>;
if (dictionary != null)
{
foreach (KeyValuePair<string, object> keyValuePair in (IEnumerable<KeyValuePair<string, object>>) dictionary)
LargeJsonValueProviderFactory.AddToBackingStore(backingStore, LargeJsonValueProviderFactory.MakePropertyKey(prefix, keyValuePair.Key), keyValuePair.Value);
}
else
{
IList list = value as IList;
if (list != null)
{
for (int index = 0; index < list.Count; ++index)
LargeJsonValueProviderFactory.AddToBackingStore(backingStore, LargeJsonValueProviderFactory.MakeArrayKey(prefix, index), list[index]);
}
else
backingStore.Add(prefix, value);
}
}
private static object GetDeserializedObject(ControllerContext controllerContext)
{
if (!controllerContext.HttpContext.Request.ContentType.StartsWith("application/json", StringComparison.OrdinalIgnoreCase))
return (object) null;
string end = new StreamReader(controllerContext.HttpContext.Request.InputStream).ReadToEnd();
if (string.IsNullOrEmpty(end))
return (object) null;
var serializer = new JavaScriptSerializer {MaxJsonLength = Int32.MaxValue};
return serializer.DeserializeObject(end);
}
/// <summary>Returns a JSON value-provider object for the specified controller context.</summary>
/// <returns>A JSON value-provider object for the specified controller context.</returns>
/// <param name="controllerContext">The controller context.</param>
public override IValueProvider GetValueProvider(ControllerContext controllerContext)
{
if (controllerContext == null)
throw new ArgumentNullException("controllerContext");
object deserializedObject = LargeJsonValueProviderFactory.GetDeserializedObject(controllerContext);
if (deserializedObject == null)
return (IValueProvider) null;
Dictionary<string, object> dictionary = new Dictionary<string, object>((IEqualityComparer<string>) StringComparer.OrdinalIgnoreCase);
LargeJsonValueProviderFactory.AddToBackingStore(new LargeJsonValueProviderFactory.EntryLimitedDictionary((IDictionary<string, object>) dictionary), string.Empty, deserializedObject);
return (IValueProvider) new DictionaryValueProvider<object>((IDictionary<string, object>) dictionary, CultureInfo.CurrentCulture);
}
private static string MakeArrayKey(string prefix, int index)
{
return prefix + "[" + index.ToString((IFormatProvider) CultureInfo.InvariantCulture) + "]";
}
private static string MakePropertyKey(string prefix, string propertyName)
{
if (!string.IsNullOrEmpty(prefix))
return prefix + "." + propertyName;
return propertyName;
}
private class EntryLimitedDictionary
{
private static int _maximumDepth = LargeJsonValueProviderFactory.EntryLimitedDictionary.GetMaximumDepth();
private readonly IDictionary<string, object> _innerDictionary;
private int _itemCount;
public EntryLimitedDictionary(IDictionary<string, object> innerDictionary)
{
this._innerDictionary = innerDictionary;
}
public void Add(string key, object value)
{
if (++this._itemCount > LargeJsonValueProviderFactory.EntryLimitedDictionary._maximumDepth)
throw new InvalidOperationException("JsonValueProviderFactory_RequestTooLarge");
this._innerDictionary.Add(key, value);
}
private static int GetMaximumDepth()
{
NameValueCollection appSettings = ConfigurationManager.AppSettings;
if (appSettings != null)
{
string[] values = appSettings.GetValues("aspnet:MaxJsonDeserializerMembers");
int result;
if (values != null && values.Length > 0 && int.TryParse(values[0], out result))
return result;
}
return 1000;
}
}
}
Then, in the Application_Start method from Global.asax.cs, replace the ValueProviderFactory with the new one:
protected void Application_Start()
{
...
//Add LargeJsonValueProviderFactory
ValueProviderFactory jsonFactory = null;
foreach (var factory in ValueProviderFactories.Factories)
{
if (factory.GetType().FullName == "System.Web.Mvc.JsonValueProviderFactory")
{
jsonFactory = factory;
break;
}
}
if (jsonFactory != null)
{
ValueProviderFactories.Factories.Remove(jsonFactory);
}
var largeJsonValueProviderFactory = new LargeJsonValueProviderFactory();
ValueProviderFactories.Factories.Add(largeJsonValueProviderFactory);
}
Below is how I got this working.
The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.
[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]
[HttpPost]
public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)
{
var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
}
The JQuery script used to call this action method:
var requestData = {
InvoiceNumber: $.trim(this.value),
SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
};
$.ajax({
url: '/en/myController/GetDataForInvoiceNumber',
type: 'POST',
data: JSON.stringify(requestData),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
error: function (xhr) {
alert('Error: ' + xhr.statusText);
},
success: function (result) {
CheckIfInvoiceFound(result);
},
async: true,
processData: false
});
I had hit this when I was trying to initiate a SOAP request from Java code. What worked for me was:
Get the Server certificate by hitting the URL in browser: http://docs.bvstools.com/home/ssl-documentation/exporting-certificate-authorities-cas-from-a-website This link has all the steps to get the server certificate
Once you have the server certificate with you follow http://java.globinch.com/enterprise-java/security/pkix-path-building-failed-validation-sun-security-validatorexception/#Valid-Certification-Path-to-Requested-Target .
Copying the text from the link, in case this link dies:
All you need to do to fix this error is to add the server certificate to your trusted Java key store. First You need to download the document from the server.
Once you have the certificate in your hard drive you can import it to the Java trust store. To import the certificate to the trusted Java key store, you can use the java ‘keytool‘ tool. On command prompt navigate to JRE bin folder, in my case the path is : C:\Program Files\Java\jdk1.7.0_75\jre\bin . Then use keytool command as follows to import the certificate to JRE.
keytool -import -alias _alias_name_ -keystore ..\lib\security\cacerts -file _path_to_cer_file
It will ask for a password. By default the password is “changeit”. If the password is different you may not be able to import the certificate.
I am a bit too late but I found this to be the simplest way to calculate a birth date.
Hopefully this will help.
function init() {
writeYears("myage", 0, Age());
}
function Age() {
var birthday = new Date(1997, 02, 01), //Year, month-1 , day.
today = new Date(),
one_year = 1000 * 60 * 60 * 24 * 365;
return Math.floor((today.getTime() - birthday.getTime()) / one_year);
}
function writeYears(id, current, maximum) {
document.getElementById(id).innerHTML = current;
if (current < maximum) {
setTimeout(function() {
writeYears(id, ++current, maximum);
}, Math.sin(current / maximum) * 200);
}
}
init()
_x000D_
<span id="myage"></span>
_x000D_
For a simple and effective PDF viewer, when you require only limited functionality, you can now (iOS 4.0+) use the QuickLook framework:
First, you need to link against QuickLook.framework
and #import
<QuickLook/QuickLook.h>;
Afterwards, in either viewDidLoad
or any of the lazy initialization methods:
QLPreviewController *previewController = [[QLPreviewController alloc] init];
previewController.dataSource = self;
previewController.delegate = self;
previewController.currentPreviewItemIndex = indexPath.row;
[self presentModalViewController:previewController animated:YES];
[previewController release];
If you want to only get fullyears as age, there is a supersimple way on doing that. treat dates formatted as 'YYYYMMDD' as numbers and substract them. After that cancel out the MMDD part by dividing the result with 10000 and floor it down. Simple and never fails, even takes to account leapyears and your current server time ;)
Since birthdays or mostly provided by full dates on birth location and they are relevant to CURRENT LOCAL TIME (where the age check is actually done).
$now = date['Ymd'];
$birthday = '19780917'; #september 17th, 1978
$age = floor(($now-$birthday)/10000);
so if you want to check if someone is 18 or 21 or below 100 on your timezone (nevermind the origin timezone) by birthday, this is my way to do this
You can create an ExpandoObject like this:
IDictionary<string,object> expando = new ExpandoObject();
expando["Name"] = value;
And after casting it to dynamic, those values will look like properties:
dynamic d = expando;
Console.WriteLine(d.Name);
However, they are not actual properties and cannot be accessed using Reflection. So the following statement will return a null:
d.GetType().GetProperty("Name")
This also works if you are looping over an object.
unset($object->$key);
No need to use brackets.
I suddenly experienced this error, and the solution for me was to disable to run tests in parallel.
Your milage may vary, since I could lower number of failing tests by configuring surefire to run parallel tests by ´classes´.:
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.2</version>
<configuration>
<parallel>classes</parallel>
<threadCount>10</threadCount>
</configuration>
</plugin>
As I wrote first, this was not enough for my test suite, so I completely disabled parallel by removing the <configuration>
section.
Here is a Javascript solution (for folks like me who were looking for an answer to the title):
function SaveToDisk(fileURL, fileName) {
// for non-IE
if (!window.ActiveXObject) {
var save = document.createElement('a');
save.href = fileURL;
save.target = '_blank';
save.download = fileName || 'unknown';
var evt = new MouseEvent('click', {
'view': window,
'bubbles': true,
'cancelable': false
});
save.dispatchEvent(evt);
(window.URL || window.webkitURL).revokeObjectURL(save.href);
}
// for IE < 11
else if ( !! window.ActiveXObject && document.execCommand) {
var _window = window.open(fileURL, '_blank');
_window.document.close();
_window.document.execCommand('SaveAs', true, fileName || fileURL)
_window.close();
}
}
source: http://muaz-khan.blogspot.fr/2012/10/save-files-on-disk-using-javascript-or.html
Unfortunately the working for me with IE11, which is not accepting new MouseEvent. I use the following in that case:
//...
try {
var evt = new MouseEvent(...);
} catch (e) {
window.open(fileURL, fileName);
}
//...
I achieved the same thing using a local web server and PHP. I used a script containing shell_exec
to launch an application locally.
Alternatively, you could do something like this:
<a href="file://C:/Windows/notepad.exe">Notepad</a>
This seems considerably easier than what anyone else has suggested
select sysdate-to_date('30-jul-1977') from dual;
This exception may also occur if you are using Socket
s on one side and SSLSocket
s on the other. Consistency is important.
One suggestion is that use a pdf library like PDFJS.
Yo have to append, the following "data:application/pdf;base64"
+ your pdf String, and set the src of your element to that.
Try with this example:
var pdfsrc = "data:application/pdf;base64" + "67987yiujkhkyktgiyuyhjhgkhgyi...n"
<pdf-element id="pdfOpen" elevation="5" downloadable src="pdfsrc" ></pdf-element>
Hope it helps :)
I use Ubuntu linux, and in my case the error was caused by incorrect statement syntax (which I found out by typing perror 150 at the terminal, which gives
MySQL error code 150: Foreign key constraint is incorrectly formed
Changing the syntax of the query from
alter table scale add constraint foreign key (year_id) references year.id;
to
alter table scale add constraint foreign key (year_id) references year(id);
fixed it.
Yes you can.
See the code from the following thread from 2007: PDF within a DIV
<div>
<object data="test.pdf" type="application/pdf" width="300" height="200">
alt : <a href="test.pdf">test.pdf</a>
</object>
</div>
It uses <object>
, which can be styled with CSS, and so you can float them, give them borders, etc.
(In the end, I edited my pdf files to remove large borders and converted them to jpg images.)

I made a thing that doesn't break the existing Storage objects, but creates a wrapper so you can do what you want. The result is a normal object, no methods, with access like any object.
If you want 1 localStorage
property to be magic:
var prop = ObjectStorage(localStorage, 'prop');
If you need several:
var storage = ObjectStorage(localStorage, ['prop', 'more', 'props']);
Everything you do to prop
, or the objects inside storage
will be automatically saved into localStorage
. You're always playing with a real object, so you can do stuff like this:
storage.data.list.push('more data');
storage.another.list.splice(1, 2, {another: 'object'});
And every new object inside a tracked object will be automatically tracked.
The very big downside: it depends on Object.observe()
so it has very limited browser support. And it doesn't look like it'll be coming for Firefox or Edge anytime soon.

Answer updated for 2020:
Both <object>
and <embed>
are included in the WHAT-WG HTML Living Standard (Sept 2020).
<object>
The object element can represent an external resource, which, depending on the type of the resource, will either be treated as an image, as a child browsing context, or as an external resource to be processed by a plugin.
<embed>
The embed element provides an integration point for an external (typically non-HTML) application or interactive content.
Are there advantages/disadvantages to using one tag vs. the other?
The opinion of Mozilla Developer Network (MDN) appears (albeit fairly subtly) to very marginally favour <object>
over <embed>
but overwhelmingly, MDN, wants to recommend that wherever you can, you avoid embedding external content entirely.
[...] you are unlikely to use these elements very much — Applets haven't been used for years, Flash is no longer very popular, due to a number of reasons (see The case against plugins, below), PDFs tend to be better linked to than embedded, and other content such as images and video have much better, easier elements to handle those. Plugins and these embedding methods are really a legacy technology, and we are mainly mentioning them in case you come across them in certain circumstances like intranets, or enterprise projects.
Once upon a time, plugins were indispensable on the Web. Remember the days when you had to install Adobe Flash Player just to watch a movie online? And then you constantly got annoying alerts about updating Flash Player and your Java Runtime Environment. Web technologies have since grown much more robust, and those days are over. For virtually all applications, it's time to stop delivering content that depends on plugins and start taking advantage of Web technologies instead.
One more possibility, if you don't want to use ArgumentCaptor
(for example, because you're also using stubbing), is to use Hamcrest Matchers in combination with Mockito.
import org.mockito.Mockito
import org.hamcrest.Matchers
...
Mockito.verify(mockedObject).someMethodOnMockedObject(MockitoHamcrest.argThat(
Matchers.<SomeObjectAsArgument>hasProperty("propertyName", desiredValue)));
@Michiel is correct to create a button but the code for ActionScript 3 it is a little different - where movieClipName is the name of your 'button'.
movieClipName.addEventListener(MouseEvent.CLICK, callLink);
function callLink:void {
var url:String = "http://site";
var request:URLRequest = new URLRequest(url);
try {
navigateToURL(request, '_blank');
} catch (e:Error) {
trace("Error occurred!");
}
}

Yes with the help of Arrays you can initialize array list in one line,
List<String> strlist= Arrays.asList("aaa", "bbb", "ccc");
Perfectly simple use of aggregate (equivalent to fold in other languages):
var firstBorn = People.Aggregate((min, x) => x.DateOfBirth < min.DateOfBirth ? x : min);
The only downside is that the property is accessed twice per sequence element, which might be expensive. That's hard to fix.
I have a solution for this but not sure on the reason why this would be different from one environment to the other - although one big difference between the two environments is WSS svc pack 1 was installed on the environment where the error was occurring.
To fix this issue I got a good clue from this link - http://silverlight.net/forums/t/22787.aspx ie to "please check the Xml Schema of your service" and "the sequence in the schema is sorted alphabetically"
Looking at the wsdl generated I noticed that for the serialized class that was causing the error, the properties of this class were not visible in the wsdl.
The Definition of the class had private setters for most of the properties, but not for CustomFields property ie..
[Serializable]
public class FileMetaDataDto

.
public int Id { get; private set; }
public string Version { get; private set; }
public List<MetaDataValueDto> CustomFields { get; set; }
}
On removing private from the setter and redeploying the service then looking at the wsdl again, these properties were now visible, and the original error was fixed.
So the wsdl before update was
- <s:complexType name="ArrayOfFileMetaDataDto">
- <s:sequence>
<s:element minOccurs="0" maxOccurs="unbounded" name="FileMetaDataDto" nillable="true" type="tns:FileMetaDataDto" />
</s:sequence>

The solution provided by Rashack does not work for value types (int, enums, etc.) unfortunately.
For it to work with any type of property, this is the solution I found:
public static Expression<Func<T, object>> GetLambdaExpressionFor<T>(this string sortColumn)
{
var type = typeof(T);
var parameterExpression = Expression.Parameter(type, "x");
var body = Expression.PropertyOrField(parameterExpression, sortColumn);
var convertedBody = Expression.MakeUnary(ExpressionType.Convert, body, typeof(object));
var expression = Expression.Lambda<Func<T, object>>(convertedBody, new[] { parameterExpression });
return expression;
}
Also to maintain accessibility, you should use this to determine your keycode:
c = e.which ? e.which : e.keyCode;
if (c == 13) ...
I had this problem with a ComboBox displaying a list of colors ( List<Brush> ).
Selecting a color was possible but it wasnt displayed when the selection closed (although the property was changed!)
The fix was overwriting the Equals(object obj) method for the type selected in the ComboBox (Brush), which wasnt simple because Brush is sealed. So i wrote a class EqualityBrush containing a Brush and implementing Equals:
public class EqualityBrush
{
public SolidColorBrush Brush { get; set; }
public override bool Equals(object o)
{
if (o is EqualityBrush)
{
SolidColorBrush b = ((EqualityBrush)o).Brush;
return b.Color.R == this.Brush.Color.R && b.Color.G == this.Brush.Color.G && b.Color.B == this.Brush.Color.B;
}
else
return false;
}
}
Using a List of my new EqualityBrush class instead of normal Brush class fixed the problem!
My Combobox XAML looks like this:
<ComboBox ItemsSource="{Binding BuerkertBrushes}" SelectedItem="{Binding Brush, Mode=TwoWay}" Width="40">
<ComboBox.Resources>
<DataTemplate DataType="{x:Type tree:EqualityBrush}">
<Rectangle Width="20" Height="12" Fill="{Binding Brush}"/>
</DataTemplate>
</ComboBox.Resources>
</ComboBox>
Remember that my "Brush"-Property in the ViewModel now has to be of Type EqualityBrush!

It's for version 7 but all the arguments I tried worked.
As for closing the file, I think you will need to use the SDK, or if you are opening the file from code you could close the file from code once you have finished with it.
How are you setting up the SqlParameter
? You should set the SqlDbType
property to SqlDbType.DateTime
and then pass the DateTime
directly to the parameter (do NOT convert to a string, you are asking for a bunch of problems then).
You should be able to get the value into the DB. If not, here is a very simple example of how to do it:
static void Main(string[] args)
{
// Create the connection.
using (SqlConnection connection = new SqlConnection(@"Data Source=..."))
{
// Open the connection.
connection.Open();
// Create the command.
using (SqlCommand command = new SqlCommand("xsp_Test", connection))
{
// Set the command type.
command.CommandType = System.Data.CommandType.StoredProcedure;
// Add the parameter.
SqlParameter parameter = command.Parameters.Add("@dt",
System.Data.SqlDbType.DateTime);
// Set the value.
parameter.Value = DateTime.Now;
// Make the call.
command.ExecuteNonQuery();
}
}
}
I think part of the issue here is that you are worried that the fact that the time is in UTC is not being conveyed to SQL Server. To that end, you shouldn't, because SQL Server doesn't know that a particular time is in a particular locale/time zone.
If you want to store the UTC value, then convert it to UTC before passing it to SQL Server (unless your server has the same time zone as the client code generating the DateTime
, and even then, that's a risk, IMO). SQL Server will store this value and when you get it back, if you want to display it in local time, you have to do it yourself (which the DateTime
struct will easily do).
All that being said, if you perform the conversion and then pass the converted UTC date (the date that is obtained by calling the ToUniversalTime
method, not by converting to a string) to the stored procedure.
And when you get the value back, call the ToLocalTime
method to get the time in the local time zone.
I had to copy the non-input boxes text (text within any div/span tag) from the page and came up with following code. The only trick is to have a hidden field, but as type TEXT. It won't work with type hidden.
function copyToClipboard(sID) {
var aField = document.getElementById("hiddenField");
aField.hidden = false;
aField.value = document.getElementById(sID).textContent;
aField.select();
document.execCommand("copy");
alert("Following text has been copied to the clipboard.\n\n" + aField.value);
aField.hidden = true;
}
And in the HTML add the following:
input type="text" id="hiddenField" style="width:5px;border:0" />
...
I had the same problem and came across this post. Nothing worked. After randomly playing around, I found that <embed ........ play="false">
stopped it from playing automatically. I now have the problem that I can't get a controller to appear, so can't start the movie! :S
if you are using angularjs & aspnet/mvc, to retrieve json files, you have to allow mime type at web config
<staticContent>
<remove fileExtension=".json" />
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
In a Ruby on Rails application (especially with something like the Prawn gem and the Prawnto Rails plugin), you can accomplish this a little more simply than a full on script (like the previous PHP example).
In your controller:
def index
respond_to do |format|
format.html # Your HTML view
format.pdf { render :layout => false }
end
end
The render :layout => false part tells the browser to open up the "Would you like to download this file?" prompt instead of attempting to render the PDF. Then you would be able to link to the file normally: http://mysite.com/myawesomepdf.pdf
Another way for PHP >= 5.3.0:
$customer['address'] = '123 fake st';
$customer['name'] = 'Tim';
$customer['dob'] = '12/08/1986';
$customer['dontSortMe'] = 'this value doesnt need to be sorted';
$customerSorted = array_replace(array_flip(array('name', 'dob', 'address')), $customer);
Result:
Array (
[name] => Tim
[dob] => 12/08/1986
[address] => 123 fake st
[dontSortMe] => this value doesnt need to be sorted
)
Works fine with string and numeric keys.

With ES2015/ES6 String.Prototype.Normalize(),

Two things are happening here:

Unicode normal form decomposes combined graphemes into the combination of simple ones. Theè

Alternatively, if you just want sorting
Intl.Collator has sufficient support ~85% right now, a polyfill is also available here but I haven't tested it.
const c = new Intl.Collator(); ['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé', 'creme brulay', 'creme brulfé', 'creme bruléa'].sort(c.compare) [ 'crame brulai','creme brulay','creme bruléa','creme brulee', 'crème brulée','creme brulfé','crome brouillé' ] ['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé'].sort((a,b) => a>b) ["crame brulai", "creme brulee", "crome brouillé", "crème brulée"]
Open the table in PGAdmin and in the SQL pane at the bottom copy the SQL Create Table statement. Then open the Query Tool and paste. If the table has data, change the table name to 'new_name', if not, delete the comment "--" in the Drop Table line. Edit the column sequence as required. Mind the missing/superfluous comma in the last column in case you have moved it. Execute the new SQL Create Table command. Refresh and ... voilà.
For empty tables in the design stage this method is quite practical.
In case the table has data, we need to rearrange the column sequence of the data as well. This is easy: use INSERT
to import the old table into its new version with:
INSERT INTO new ( c2, c3, c1 ) SELECT * from old;
... where c2
, c3
, c1
are the columns c1
, c2
, c3
of the old table in their new positions. Please note that in this case you must use a 'new' name for the edited 'old' table, or you will lose your data. In case the column names are many, long and/or complex use the same method as above to copy the new table structure into a text editor, and create the new column list there before copying it into the INSERT
statement.
After checking that all is well, DROP
the old table and change the the 'new' name to 'old' using ALTER TABLE new RENAME TO old;
and you are done.
You seem to be aware already, but I'll just restate it anyway; It's a bad sign, if you need to test protected methods. The aim of a unit test, is to test the interface of a class, and protected methods are implementation details. That said, there are cases where it makes sense. If you use inheritance, you can see a superclass as providing an interface for the subclass. So here, you would have to test the protected method (But never a private one). The solution to this, is to create a subclass for testing purpose, and use this to expose the methods. Eg.:
class Foo {
protected function stuff() {
// secret stuff, you want to test
}
}
class SubFoo extends Foo {
public function exposedStuff() {
return $this->stuff();
}
}
Note that you can always replace inheritance with composition. When testing code, it's usually a lot easier to deal with code that uses this pattern, so you may want to consider that option.
For MySql Server 8.0 The default location is %WINDIR% or C:\Windows.
You need to add a "my.ini" file there.
Here's a sample of what I put in the ini file.
[mysqld]
secure_file_priv=""
Make sure to restart the MySQL service after that.
This code works too:
$("input[reference=12345].myclass").css('border', '#000 solid 1px');
$('#' + catId).parent().remove('.subcatBtns');
For example, like this:
const querystring = require('querystring');
const https = require('https');
var postData = querystring.stringify({
'msg' : 'Hello World!'
});
var options = {
hostname: 'posttestserver.com',
port: 443,
path: '/post.php',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': postData.length
}
};
var req = https.request(options, (res) => {
console.log('statusCode:', res.statusCode);
console.log('headers:', res.headers);
res.on('data', (d) => {
process.stdout.write(d);
});
});
req.on('error', (e) => {
console.error(e);
});
req.write(postData);
req.end();
As short as the question:
SELECT DeptID, MAX(Salary) FROM EmpDetails GROUP BY DeptID
First of all, your selector is overkill. I suggest using a class or ID selector like my example below. Once you've corrected your selector, simply use jQuery's .each() to iterate through the collection:
ID Selector:
$('#mytable td').each(function() {
var cellText = $(this).html();
});
Class Selector:
$('.myTableClass td').each(function() {
var cellText = $(this).html();
});
Additional Information:
Take a look at jQuery's selector docs.
If you are interested in ImageButton you can try this simple thing :
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@android:drawable/ic_button"
android:background="?attr/selectableItemBackgroundBorderless"
/>
If you want to use the toDF
method, you have to convert your RDD
of Array[String]
into a RDD
of a case class. For example, you have to do:
case class Test(id:String,filed2:String)
val myFile = sc.textFile("file.txt")
val df= myFile.map( x => x.split(";") ).map( x=> Test(x(0),x(1)) ).toDF()
Don't use os.system
. It has been deprecated in favor of subprocess. From the docs: "This module intends to replace several older modules and functions: os.system
, os.spawn
".
Like in your case:
bashCommand = "cwm --rdf test.rdf --ntriples > test.nt"
import subprocess
process = subprocess.Popen(bashCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
I think what you are asking is the difference between RPC Literal, Document Literal and Document Wrapped SOAP web services.
Note that Document web services are delineated into literal and wrapped as well and they are different - one of the primary difference is that the latter is BP 1.1 compliant and the former is not.
Also, in Document Literal the operation to be invoked is not specified in terms of its name whereas in Wrapped, it is. This, I think, is a significant difference in terms of easily figuring out the operation name that the request is for.
In terms of RPC literal versus Document Wrapped, the Document Wrapped request can be easily vetted / validated against the schema in the WSDL - one big advantage.
I would suggest using Document Wrapped as the web service type of choice due to its advantages.
SOAP on HTTP is the SOAP protocol bound to HTTP as the carrier. SOAP could be over SMTP or XXX as well. SOAP provides a way of interaction between entities (client and servers, for example) and both entities can marshal operation arguments / return values as per the semantics of the protocol.
If you were using XML over HTTP (and you can), it is simply understood to be XML payload on HTTP request / response. You would need to provide the framework to marshal / unmarshal, error handling and so on.

Here is a basic hover example.
Component's template property:

<!-- attention, we have the c_highlight class -->
<!-- c_highlight is the selector property value of the directive -->
<p class="c_highlight">

And our directive
import {Component,HostListener,Directive,HostBinding} from '@angular/core';
@Directive({
// this directive will work only if the DOM el has the c_highlight class
selector: '.c_highlight'
})
export class HostDirective {
// we could pass lots of thing to the HostBinding function.
// like class.valid or attr.required etc.
@HostBinding('style.backgroundColor') c_colorrr = "red";
@HostListener('mouseenter') c_onEnterrr() {
this.c_colorrr= "blue" ;
}
@HostListener('mouseleave') c_onLeaveee() {
this.c_colorrr = "yellow" ;
}
}

In the meantime there are some ways to navigate around the code based on your navigation history. You can Ctrl+Tab to quickly jump to previously opened files. You can also navigate within your code based on cursor positions using Goto | Back and Goto | Forward.

, if you can check this with a simple if
statement ... you loop over a whole range while you can simply check whether it is contained in that rangeA
you will have your result the first time you enter the first loop) you still loop over all the restSystem.out.println("Lowercase");
statement (and the uppercase statement) are placed in the wrong loopCharacter

return items.Distinct(comparer);
}
}
public class GeneralPropertyComparer<T,TKey> : IEqualityComparer<T>
{
private Func<T, TKey> expr { get; set; }
public GeneralPropertyComparer (Func<T, TKey> expr)
{
this.expr = expr;
}
public bool Equals(T left, T right)
{
var leftProp = expr.Invoke(left);
var rightProp = expr.Invoke(right);
if (leftProp == null && rightProp == null)
return true;
else if (leftProp == null ^ rightProp == null)
return false;
else
return leftProp.Equals(rightProp);
}
public int GetHashCode(T obj)
{
var prop = expr.Invoke(obj);
return (prop==null)? 0:prop.GetHashCode();

This is one way. there are a lot of others if you google SQL Paging.
If you have multiple occurrences of an element name, then you have to use forEach().
html
<input type="checkbox" name="delete" id="flizzit" />
<input type="checkbox" name="delete" id="floo" />
<input type="checkbox" name="delete" id="flum" />
<input type="submit" value="Save" onClick={evt => saveAction(evt)}></input>
js
const submitAction = (evt) => {
evt.preventDefault();
const dels = evt.target.parentElement.delete;
const deleted = [];
dels.forEach((d) => { if (d.checked) deleted.push(d.id); });
window.alert(deleted.length);
};
Note the dels in this case is a RadioNodeList, not an array, and is not an Iterable. The forEach()is a built-in method of the list class. You will not be able to use a map() or reduce() here.
You can get the managed bean by passing the name:
public static Object getBean(String beanName){
Object bean = null;
FacesContext fc = FacesContext.getCurrentInstance();
if(fc!=null){
ELContext elContext = fc.getELContext();
bean = elContext.getELResolver().getValue(elContext, null, beanName);
}
return bean;
}
SHOW COLUMNS FROM //table_name// ;
It will give you information about all the columns from the table .

Vue.use(Vuex);
export const messages = new Vuex.Store();
Vue.use(vuexI18n.plugin, messages);
Vue.i18n.add('en', translationsEn);

It depends on the tablix structure you are using. In a table, for example, you do not have column groups, so Reporting Services does not recognize which textboxes are the column headers and setting RepeatColumnHeaders property to True doesn't work.
Instead, you need to:
RepeatOnNewPage
property to True.
KeepWithGroup
property is set to After
.The KeepWithGroup
property specifies which group to which the static member needs to stick. If set to After
then the static member sticks with the group after it, or below it, acting as a group header. If set to Before
, then the static member sticks with the group before, or above it, acting as a group footer. If set to None
, Reporting Services decides where to put the static member.
Now when you view the report, the column headers repeat on each page of the tablix.
This video shows how to set it exactly as the answer described.

EDIT: Placed the missing first curly brace.
Inline-block is a halfway point between setting an element’s display to inline or to block. It keeps the element in the inline flow of the document like display:inline does, but you can manipulate the element’s box attributes (width, height and vertical margins) like you can with display:block.
We must not use block elements within inline elements. This is invalid and there is no reason to do such practices.
event.target
returns the node that was targeted by the function. This means you can do anything you want to do with any other node like one you'd get from document.getElementById

Return an error :
.attr not function
But _target.attributes.href.value

You can use the Closure compiler to compile your javascript.
You can also use CoffeeScript to compile your coffeescript to javascript.
What do you want to achieve with compiling?
The task of compiling arbitrary non-blocking JavaScript down to say, C sounds very daunting.
There really isn't that much speed to be gained by compiling to C or ASM. If you want speed gain offload computation to a C program through a sub process.

You Can Now Delete App.
On October 4, 2018, Apple released a new update of the appstoreconnect (previously iTunesConnect).
It's now easier to manage apps you no longer need in App Store Connect by removing them from your main view in My Apps, even if they haven't been submitted for approval. You must have the Legal or Admin role to remove apps.
From the homepage, click My Apps, then choose the app you want to remove. Scroll to the Additional Information section, then click Remove App. In the dialog that appears, click Remove. You can restore a removed app at any time, as long as the app name is not currently in use by another developer.
From the homepage, click My Apps. In the upper right-hand corner, click the arrow next to All Statuses. From the drop-down menu, choose Removed Apps. Choose the app you want to restore. Scroll to the Additional Information section, then click Restore App.
You can show the removed app by clicking on all Statuses on the top right of the screen and then select Removed Apps. Thank you @Daniel for the tips.
Please note:
you can only remove apps if all versions of that app are in one of the following states: Prepare for Submission, Invalid Binary, Developer Rejected, Rejected, Metadata Rejected, Developer, Removed from Sale.
You could try mixing Number()

Perhaps the best way is to write a script that starts the mysql command line client and then automatically runs whatever sql you want before it hands over the control to you.
linux comes with an application called 'expect'. it interacts with the shell in such a way as to mimic your key strokes. it can be set to start mysql, wait for you to enter your password. run further commands such as SET autocommit = 0;
then go into interactive mode so you can run any command you want.
for more on the command SET autocommit = 0;
see.. http://dev.mysql.com/doc/refman/5.0/en/innodb-transaction-model.html
I use expect to log in to a command line utility in my case it starts ssh, connects to the remote server, starts the application enters my username and password then turns over control to me. saves me heaps of typing :)
http://linux.die.net/man/1/expect
DC
Expect script provided by Michael Hinds
spawn /usr/local/mysql/bin/mysql
expect "mysql>"
send "set autocommit=0;\r"
expect "mysql>" interact
expect is pretty powerful and can make life a lot easier as in this case.
if you want to make the script run without calling expect use the shebang line
insert this as the first line in your script (hint: use which expect
to find the location of your expect executable)
#! /usr/bin/expect
then change the permissions of your script with..
chmod 0744 myscript
then call the script
./myscript
DC
My preferred option in this circumstance is to use org.apache.commons.codec.binary.Hex
which has useful APIs for converting between String
y hex and binary. For example:
Hex.decodeHex(char[] data)
which throws a DecoderException
if there are non-hex characters in the array, or if there are an odd number of characters.
Hex.encodeHex(byte[] data)
is the counterpart to the decode method above, and spits out the char[]
.
Hex.encodeHexString(byte[] data)
which converts back from a byte
array to a String
.
Usage: Hex.decodeHex("dd645a2564cbe648c8336d2be5eafaa6".toCharArray())
I am assuming that you have enough permissions to create this directory.
To fix your problem, you can either ssh to some other location:
ssh [email protected]
and accept new key - it will create directory ~/.ssh
and known_hosts
underneath, or simply create it manually using
mkdir ~/.ssh
chmod 700 ~/.ssh
Note that chmod 700
is an important step!
After that, ssh-keygen should work without complaints.
Just set the property directly: .
eleman.disabled = false;
Running the apc.php script is key to understanding what your problem is, IMO. This helped us size our cache properly and for the moment, seems to have resolved the problem.
You can use the this
parameter of the filter()
function to avoid to store your filter array in a global variable.
var filtered = [1, 2, 3, 4].filter(_x000D_
function(e) {_x000D_
return this.indexOf(e) < 0;_x000D_
},_x000D_
[2, 4]_x000D_
);_x000D_
console.log(filtered);
_x000D_
$("input").on("keydown",function search(e) {
if(e.keyCode == 13) {
alert($(this).val());
}
});

Now that GDPR is a thing, people visiting this question probably use a cookie script. Well, that script caused the problem for me. Apparently, PHP uses a cookie called PHPSESSID
to track the session. If that script deletes it, you lose your data.
I used this cookie script. It has an option to enable "essential" cookies. I added PHPSESSID
to the list, the script stopped deleting the cookie, and everything started to work again.
You could probably enable some PHP setting to avoid using PHPSESSID
, but if your cookie script is the cause of the problem, why not fix that.
I'm not sure what the problem is; running the below works as expected:
<div id="thumb0" class="thumbs" onclick="klikaj('rad1')">knock knock</div>
?<div id="rad1" style="visibility: hidden">hello world</div>????????????????????????????????
<script>
function klikaj(i) {
document.getElementById(i).style.visibility='visible';
}
</script>

It's an very important improvement for npm: guarantee exact same version of every package.
How to make sure your project built with same packages in different environments in a different time? Let's say, you may use ^1.2.3
in your package.json
, or some of your dependencies are using that way, but how can u ensure each time npm install
will pick up same version in your dev machine and in the build server? package-lock.json will ensure that.
npm install
will re-generate the lock file, when on build server or deployment server, do npm ci
(which will read from the lock file, and install the whole package tree)
copy *.txt all.txt
This will concatenate all text files of the folder to one text file all.txt
If you have any other type of files, like sql files
copy *.sql all.sql
I have a very simple working example of geting pixel color from canvas.
First some basic HTML:
<canvas id="myCanvas" width="400" height="250" style="background:red;" onmouseover="echoColor(event)">
</canvas>
Then JS to draw something on the Canvas, and to get color:
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
ctx.fillStyle = "black";
ctx.fillRect(10, 10, 50, 50);
function echoColor(e){
var imgData = ctx.getImageData(e.pageX, e.pageX, 1, 1);
red = imgData.data[0];
green = imgData.data[1];
blue = imgData.data[2];
alpha = imgData.data[3];
console.log(red + " " + green + " " + blue + " " + alpha);
}
Here is a working example, just look at the console.
You just need to make sure you have the rights to push to the remote repository and do
git push origin master
or simply
git push
you are using onclick
which is javascript event.
there is two ways
Javascript
<input type="button" value="Home" class="homebutton" id="btnHome"
onClick="window.location = 'http://google.com'" />
Or PHP
create another page as redirect.php and put
<?php header('location : google.com') ?>
and insert this link on any page within the same directory
<a href="redirect.php">google<a/>
hope this helps its simplest!!
You can do this by using JQuery.
For example ,
<a href="your URL" id="navigate"> click here </a>
Your JQuery
will be,
$(document).ready(function(){
$('a').on('mousedown', stopNavigate);
$('a').on('mouseleave', function () {
$(window).on('beforeunload', function(){
return 'Are you sure you want to leave?';
});
});
});
function stopNavigate(){
$(window).off('beforeunload');
}
And to get the Leave message alert will be,
$(window).on('beforeunload', function(){
return 'Are you sure you want to leave?';
});
$(window).on('unload', function(){
logout();
});
This solution works in all browsers and I have tested it.
Since everyone else is posting their methods, I figured I'd post the extension method I usually use for this:
EDIT: added int/long variants...and fixed a copypasta typo...

private const long OneMb = OneKb * 1024;
private const long OneGb = OneMb * 1024;
private const long OneTb = OneGb * 1024;
public static string ToPrettySize(this int value, int decimalPlaces = 0)
{
return ((long)value).ToPrettySize(decimalPlaces);
}
public static string ToPrettySize(this long value, int decimalPlaces = 0)
{
var asTb = Math.Round((double)value / OneTb, decimalPlaces);
var asGb = Math.Round((double)value / OneGb, decimalPlaces);
var asMb = Math.Round((double)value / OneMb, decimalPlaces);
var asKb = Math.Round((double)value / OneKb, decimalPlaces);
string chosenValue = asTb > 1 ? string.Format("{0}Tb",asTb)
: asGb > 1 ? string.Format("{0}Gb",asGb)
: asMb > 1 ? string.Format("{0}Mb",asMb)
: asKb > 1 ? string.Format("{0}Kb",asKb)
: string.Format("{0}B", Math.Round((double)value, decimalPlaces));
return chosenValue;
}
}

Check if you have a android-support-v4.jar
file in YOUR project's lib folder, it should be removed!
In the tutorial, when you have followed the instructions of Adding libraries WITHOUT resources
before doing the coorect Adding libraries WITH resources
you'll get the same error.
(Don't know why someone would do something like that *lookingawayfrommyself* ^^)
So what did fix it in my case, was removing the android-support-v4.jar
from YOUR PROJECT (not the android-support-v7-appcompat project), since this caused some kind of library collision (maybe because in the meantime there was a new version of the suport library).
Just another case, when this error might shows up.
The answer from @laughing_man is quite accurate. But still, I wanted to give a recommendation which I learned from Kafka expert Stephane Maarek.
Kafka isn’t meant to handle large messages.
Your API should use cloud storage (Ex AWS S3), and just push to Kafka or any message broker a reference of S3. You must find somewhere to persist your data, maybe it’s a network drive, maybe it’s whatever, but it shouldn't be message broker.
Now, if you don’t want to go with the above solution
The message max size is 1MB (the setting in your brokers is called message.max.bytes
) Apache Kafka. If you really needed it badly, you could increase that size and make sure to increase the network buffers for your producers and consumers.
And if you really care about splitting your message, make sure each message split has the exact same key so that it gets pushed to the same partition, and your message content should report a “part id” so that your consumer can fully reconstruct the message.
You can also explore compression, if your message is text-based (gzip, snappy, lz4 compression) which may reduce the data size, but not magically.
Again, you have to use an external system to store that data and just push an external reference to Kafka. That is a very common architecture and one you should go with and widely accepted.
Keep that in mind Kafka works best only if the messages are huge in amount but not in size.

Modify your log4j.properties
file accordingly:
log4j.rootLogger=TRACE,stdout
...
log4j.logger.debugLog=TRACE,debugLog
log4j.logger.reportsLog=DEBUG,reportsLog
Change the log levels for each logger depending to your needs.
Several tips:
pragma journal_mode
). There is NORMAL
, and then there is OFF
, which can significantly increase insert speed if you're not too worried about the database possibly getting corrupted if the OS crashes. If your application crashes the data should be fine. Note that in newer versions, the OFF/MEMORY
settings are not safe for application level crashes.PRAGMA page_size
). Having larger page sizes can make reads and writes go a bit faster as larger pages are held in memory. Note that more memory will be used for your database.CREATE INDEX
after doing all your inserts. This is significantly faster than creating the index and then doing your inserts.INTEGER PRIMARY KEY
if possible, which will replace the implied unique row number column in the table.!feof(file)
!We use a combination of the processor id number (ProcessorID
) from Win32_processor
and the universally unique identifier (UUID
) from Win32_ComputerSystemProduct
:
ManagementObjectCollection mbsList = null;
ManagementObjectSearcher mos = new ManagementObjectSearcher("Select ProcessorID From Win32_processor");
mbsList = mos.Get();
string processorId = string.Empty;
foreach (ManagementBaseObject mo in mbsList)
{
processorId = mo["ProcessorID"] as string;
}
mos = new ManagementObjectSearcher("SELECT UUID FROM Win32_ComputerSystemProduct");
mbsList = mos.Get();
string systemId = string.Empty;
foreach (ManagementBaseObject mo in mbsList)
{
systemId = mo["UUID"] as string;
}
var compIdStr = $"{processorId}{systemId}";
Previously, we used a combination: processor ID ("Select ProcessorID From Win32_processor"
) and the motherboard serial number ("SELECT SerialNumber FROM Win32_BaseBoard"
), but then we found out that the serial number of the motherboard may not be filled in, or it may be filled in with uniform values:
Therefore, it is worth considering this situation.
Also keep in mind that the ProcessorID
number may be the same on different computers.
I had this error before when I was executing a python3 script, after this:
sudo pip3 install requests
the problem solved, If you are using python3, give a shot.
With Postgres 9.3+, just use the ->
operator. For example,
SELECT data->'images'->'thumbnail'->'url' AS thumb FROM instagram;
see http://clarkdave.net/2013/06/what-can-you-do-with-postgresql-and-json/ for some nice examples and a tutorial.
You can't float or set the width of an inline element. Remove display: inline;
from both classes and your markup should present fine.
EDIT: You can set the width, but it will cause the element to be rendered as a block.
My task was to implement ListView
which expands when clicked. The additional space shows EditText
where you can input some text. App should be functional on 2.2+ (up to 4.2.2 at time of writing this)
I tried numerous solutions from this post and others I could find; tested them on 2.2 up to 4.2.2 devices. None of solutions was satisfactionary on all devices 2.2+, each solution presented with different problems.
I wanted to share my final solution :
android:descendantFocusability="afterDescendants"
setItemsCanFocus(true);
android:windowSoftInputMode="adjustResize"
Many people suggest adjustPan
but adjustResize
gives much better ux imho, just test this in your case. With adjustPan
you will get bottom listitems obscured for instance. Docs suggest that ("This is generally less desirable than resizing"). Also on 4.0.4 after user starts typing on soft keyboard the screen pans to the top.adjustResize
there are some problems with EditText focus. The solution is to apply rjrjr solution from this thread. It looks scarry but it is not. And it works. Just try it.Additional 5. Due to adapter being refreshed (because of view resize) when EditText
gains focus on pre HoneyComb versions I found an issue with reversed views:
getting View for ListView item / reverse order on 2.2; works on 4.0.3
If you are doing some animations you might want to change behaviour to adjustPan
for pre-honeycomb versions so that resize doesnt fire and adapter doesn't refresh the views. You just need to add something like this
if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB)
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
All this gives acceptable ux on 2.2 - 4.2.2 devices. Hope it will save people some time as it took me at least several hours to come to this conclusion.
Use this code spinet for create intermediate folders if one doesn't exist while creating/editing file:
File outFile = new File("/dir1/dir2/dir3/test.file");
outFile.getParentFile().mkdirs();
outFile.createNewFile();
There are many valid answers already but I'd like to add anther implementation as a Type extension and a list of unit tests to demonstrate different scenarios:
public static class TypeExtensions
{
public static IEnumerable<Type> GetAllTypes(this Type type)
{
var typeInfo = type.GetTypeInfo();
var allTypes = GetAllImplementedTypes(type).Concat(typeInfo.ImplementedInterfaces);
return allTypes;
}
private static IEnumerable<Type> GetAllImplementedTypes(Type type)
{
yield return type;
var typeInfo = type.GetTypeInfo();
var baseType = typeInfo.BaseType;
if (baseType != null)
{
foreach (var foundType in GetAllImplementedTypes(baseType))
{
yield return foundType;
}
}
}
}
This algorithm supports the following scenarios:

By default, unlike an exception, a warning doesn't interrupt.
After import warnings
, it is possible to specify a Warnings class when generating a warning. If one is not specified, it is literally UserWarning
by default.
>>> warnings.warn('This is a default warning.')
<string>:1: UserWarning: This is a default warning.
To simply use a preexisting class instead, e.g. DeprecationWarning
:
>>> warnings.warn('This is a particular warning.', DeprecationWarning)
<string>:1: DeprecationWarning: This is a particular warning.
Creating a custom warning class is similar to creating a custom exception class:
>>> class MyCustomWarning(UserWarning):
... pass
...
... warnings.warn('This is my custom warning.', MyCustomWarning)
<string>:1: MyCustomWarning: This is my custom warning.
For testing, consider assertWarns
or assertWarnsRegex
.
As an alternative, especially for standalone applications, consider the logging
module. It can log messages having a level of debug, info, warning, error, etc. Log messages having a level of warning or higher are by default printed to stderr.
If you want to unstage all the changes use below command,
git reset --soft HEAD
In the case you want to unstage changes and revert them from the working directory,
git reset --hard HEAD
It's because you're casting to the wrong thing - you're trying to convert to a particular type, and the object that your express refers to is incompatible with that type. For example:
Object x = "this is a string";
InputStream y = (InputStream) x; // This will throw ClassCastException
If you could provide a code sample, that would really help...
I have created a small library (.aar) to retrieve the logs by email. You can use it with Gmail accounts. It is pretty simple but works. You can get a copy from here
The site is in Spanish, but there is a PDF with an english version of the product description.
I hope it can help.
other than using this.form.submit()
you also submiting by id or name.
example i have form like this : <form action="" name="PostName" id="IdName">
By Name : <select onchange="PostName.submit()">
By Id : <select onchange="IdName.submit()">
As mentioned in one of the answers you can use the Patterns
class as below:
public final static boolean isValidEmail(CharSequence target) {
if (target == null)
return false;
return android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
}
By chance if you are even supporting API level less than 8, then you can simply copy the Patterns.java
file into your project and reference it. You can get the source code for Patterns.java
from this link
Just pass the array to the Set constructor. The Set constructor accepts an iterable
parameter. The Array object implements the iterable
protocol, so its a valid parameter.

console.log(set.size === arr.length);_x000D_
console.log(set.has(65));

It is better to use DataView for this task.
Example of the using it you can find in this post: How to filter data in dataview
This explains better: Postman docs
Request body
While constructing requests, you would be dealing with the request body editor a lot. Postman lets you send almost any kind of HTTP request (If you can't send something, let us know!). The body editor is divided into 4 areas and has different controls depending on the body type.
form-data
multipart/form-data is the default encoding a web form uses to transfer data.This simulates filling a form on a website, and submitting it. The form-data editor lets you set key/value pairs (using the key-value editor) for your data. You can attach files to a key as well. Do note that due to restrictions of the HTML5 spec, files are not stored in history or collections. You would have to select the file again at the time of sending a request.urlencoded
This encoding is the same as the one used in URL parameters. You just need to enter key/value pairs and Postman will encode the keys and values properly. Note that you can not upload files through this encoding mode. There might be some confusion between form-data and urlencoded so make sure to check with your API first.
raw
A raw request can contain anything. Postman doesn't touch the string entered in the raw editor except replacing environment variables. Whatever you put in the text area gets sent with the request. The raw editor lets you set the formatting type along with the correct header that you should send with the raw body. You can set the Content-Type header manually as well. Normally, you would be sending XML or JSON data here.
binary
binary data allows you to send things which you can not enter in Postman. For example, image, audio or video files. You can send text files as well. As mentioned earlier in the form-data section, you would have to reattach a file if you are loading a request through the history or the collection.
UPDATE
As pointed out by VKK, the WHATWG spec say urlencoded is the default encoding type for forms.
The invalid value default for these attributes is the application/x-www-form-urlencoded state. The missing value default for the enctype attribute is also the application/x-www-form-urlencoded state.

Documentation from npm for npm install <package-name> --save
and npm install <package-name> --save-dev
can be found here:
https://docs.npmjs.com/getting-started/using-a-package.json#the-save-and-save-dev-install-flags
A package.json
file declares metadata about the module you are developing. Both aforementioned commands modify this package.json
file. --save
will declare the installed package (in this case, grunt
) as a dependency for your module; --save-dev
will declare it as a dependency for development of your module.
Ask yourself: will the installed package be required for use of my module, or will it only be required for developing it?
Are you testing/seeing this behaviour using IE? It's possible that IE is serving up those pages from the cache. It is notoriously hard to get IE to flush it's cache, and so on many occasions, even after you log out, typing the url of one of the "secured" pages would show the cached content from before.
(I've seen this behaviour even when you log as a different user, and IE shows the "Welcome " bar at the top of your page, with the old user's username. Nowadays, usually a reload will update it, but if it's persistant, it could still be a caching issue.)
In case you use jQuery you need to wait for $(window).load
, because the embedded SVG document might not be yet loaded at $(document).ready
$(window).load(function () {
//alert("Document loaded, including graphics and embedded documents (like SVG)");
var a = document.getElementById("alphasvg");
//get the inner DOM of alpha.svg
var svgDoc = a.contentDocument;
//get the inner element by id
var delta = svgDoc.getElementById("delta");
delta.addEventListener("mousedown", function(){ alert('hello world!')}, false);
});

This way you can create Observable from data, in my case I need to maintain shopping cart:
service.ts
export class OrderService {
cartItems: BehaviorSubject<Array<any>> = new BehaviorSubject([]);
cartItems$ = this.cartItems.asObservable();
// I need to maintain cart, so add items in cart
addCartData(data) {
const currentValue = this.cartItems.value; // get current items in cart
const updatedValue = [...currentValue, data]; // push new item in cart
if(updatedValue.length) {
this.cartItems.next(updatedValue); // notify to all subscribers
}
}
}
Component.ts
export class CartViewComponent implements OnInit {
cartProductList: any = [];
constructor(
private order: OrderService
) { }
ngOnInit() {
this.order.cartItems$.subscribe(items => {
this.cartProductList = items;
});
}
}

While a lot of others should be mentioned, Apache Wicket should be preferred.
Wicket doesn't just reduce lots of boilerplate code, it actually removes it entirely and you can work with excellent separation of business code and markup without mixing the two and a wide variety of other things you can read about from the website.
.NET Standard: Think of it as a big standard library. When using this as a dependency you can only make libraries (.DLLs), not executables. A library made with .NET standard as a dependency can be added to a Xamarin.Android, a Xamarin.iOS, a .NET Core Windows/OS X/Linux project.
.NET Core: Think of it as the continuation of the old .NET framework, just it's opensource and some stuff is not yet implemented and others got deprecated. It extends the .NET standard with extra functions, but it only runs on desktops. When adding this as a dependency you can make runnable applications on Windows, Linux and OS X. (Although console only for now, no GUIs). So .NET Core = .NET Standard + desktop specific stuff.
Also UWP uses it and the new ASP.NET Core uses it as a dependency too.
You should use font-size for controlling the height, it is widely supported amongst browsers. And in order to add spacing, you should use padding. Forexample,
.inputField{
font-size: 30px;
padding-top: 10px;
padding-bottom: 10px;
}
I would prefer Session.Abandon()
Session.Clear()

I did some development with Mifare Classic (ISO 14443A) cards about 7-8 years ago. You can read and write to all sectors of the card, IIRC the only data you can't change is the serial number. Back then we used a proprietary library from Philips Semiconductors. The command interface to the card was quite alike the ISO 7816-4 (used with standard Smart Cards).
I'd recomment that you look at the OpenPCD platform if you are into development.
This is also of interest regarding the cryptographic functions in some RFID cards.
Your vncserver have a configuration file somewher that set the display number. To do it automaticaly, one solution is to parse this file, extract the number and set it correctly. A simpler (better) is to have this display number set in a config script and use it in both your VNC server config and in your init scripts.
If you have a string like foo: 1, bar: 2
you can convert it to a valid obj with:
str
.split(',')
.map(x => x.split(':').map(y => y.trim()))
.reduce((a, x) => {
a[x[0]] = x[1];
return a;
}, {});
Thanks to niggler in #javascript for that.
Update with explanations:
const obj = 'foo: 1, bar: 2'
.split(',') // split into ['foo: 1', 'bar: 2']
.map(keyVal => { // go over each keyVal value in that array
return keyVal
.split(':') // split into ['foo', '1'] and on the next loop ['bar', '2']
.map(_ => _.trim()) // loop over each value in each array and make sure it doesn't have trailing whitespace, the _ is irrelavent because i'm too lazy to think of a good var name for this
})
.reduce((accumulator, currentValue) => { // reduce() takes a func and a beginning object, we're making a fresh object
accumulator[currentValue[0]] = currentValue[1]
// accumulator starts at the beginning obj, in our case {}, and "accumulates" values to it
// since reduce() works like map() in the sense it iterates over an array, and it can be chained upon things like map(),
// first time through it would say "okay accumulator, accumulate currentValue[0] (which is 'foo') = currentValue[1] (which is '1')
// so first time reduce runs, it starts with empty object {} and assigns {foo: '1'} to it
// second time through, it "accumulates" {bar: '2'} to it. so now we have {foo: '1', bar: '2'}
return accumulator
}, {}) // when there are no more things in the array to iterate over, it returns the accumulated stuff
console.log(obj)
Confusing MDN docs:
Demo: http://jsbin.com/hiduhijevu/edit?js,console
Function:
const str2obj = str => {
return str
.split(',')
.map(keyVal => {
return keyVal
.split(':')
.map(_ => _.trim())
})
.reduce((accumulator, currentValue) => {
accumulator[currentValue[0]] = currentValue[1]
return accumulator
}, {})
}
console.log(str2obj('foo: 1, bar: 2')) // see? works!

I would personally prefer using "\n". This just puts a line break in Linux or Android.
For example,
String str = "I am the first part of the info being emailed.\nI am the second part.\n\nI am the third part.";
Output
I am the first part of the info being emailed.
I am the second part.
I am the third part.
A more generalized way would be to use,
System.getProperty("line.separator")
For example,
String str = "I am the first part of the info being emailed." + System.getProperty("line.separator") + "I am the second part." + System.getProperty("line.separator") + System.getProperty("line.separator") + "I am the third part.";
brings the same output as above. Here, the static getProperty()
method of the System
class can be used to get the "line.seperator
" for the particular OS.
But this is not necessary at all, as the OS here is fixed, that is, Android. So, calling a method every time is a heavy and unnecessary operation.
Moreover, this also increases your code length and makes it look kind of messy. A "\n" is sweet and simple.
You should pass the reference to request like below
var options = { ... }_x000D_
var req = http.request(options, function(res) {_x000D_
// Usual stuff: on(data), on(end), chunks, etc..._x000D_
});_x000D_
_x000D_
req.setTimeout(60000, function(){_x000D_
this.abort();_x000D_
}).bind(req);_x000D_
req.write('something');_x000D_
req.end();
_x000D_
Request error event will get triggered
req.on("error", function(e){_x000D_
console.log("Request Error : "+JSON.stringify(e));_x000D_
});
_x000D_
// NOTE: Using "this.pass" and "this.name" will create a global variable even though it is inside the function, so be weary of your naming convention
function submit()
{
var userPass = document.getElementById("pass").value;
var userName = document.getElementById("user").value;
this.pass = userPass;
this.name = userName;
alert("whatever you want to display");

SOAP uses WSDL for communication btw consumer and provider, whereas REST just uses XML or JSON to send and receive data
WSDL defines contract between client and service and is static by its nature. In case of REST contract is somewhat complicated and is defined by HTTP, URI, Media Formats and Application Specific Coordination Protocol. It's highly dynamic unlike WSDL.
SOAP doesn't return human readable result, whilst REST result is readable with is just plain XML or JSON
This is not true. Plain XML or JSON are not RESTful at all. None of them define any controls(i.e. links and link relations, method information, encoding information etc...) which is against REST as far as messages must be self contained and coordinate interaction between agent/client and service.
With links + semantic link relations clients should be able to determine what is next interaction step and follow these links and continue communication with service.
It is not necessary that messages be human readable, it's possible to use cryptic format and build perfectly valid REST applications. It doesn't matter whether message is human readable or not.
Thus, plain XML(application/xml) or JSON(application/json) are not sufficient formats for building REST applications. It's always reasonable to use subset of these generic media types which have strong semantic meaning and offer enough control information(links etc...) to coordinate interactions between client and server.
REST is over only HTTP
Not true, HTTP is most widely used and when we talk about REST web services we just assume HTTP. HTTP defines interface with it's methods(GET, POST, PUT, DELETE, PATCH etc) and various headers which can be used uniformly for interacting with resources. This uniformity can be achieved with other protocols as well.
P.S. Very simple, yet very interesting explanation of REST: http://www.looah.com/source/view/2284
Closed formula for the longest int
(I used int
here, but works for any signed integral type):
1 + (int) ceil((8*sizeof(int)-1) * log10(2))
Explanation:
sizeof(int) // number bytes in int
8*sizeof(int) // number of binary digits (bits)
8*sizeof(int)-1 // discount one bit for the negatives
(8*sizeof(int)-1) * log10(2) // convert to decimal, because:
// 1 bit == log10(2) decimal digits
(int) ceil((8*sizeof(int)-1) * log10(2)) // round up to whole digits
1 + (int) ceil((8*sizeof(int)-1) * log10(2)) // make room for the minus sign
For an int
type of 4 bytes, the result is 11. An example of 4 bytes int
with 11 decimal digits is: "-2147483648".
If you want the number of decimal digits of some int
value, you can use the following function:
unsigned base10_size(int value)
{
if(value == 0) {
return 1u;
}
unsigned ret;
double dval;
if(value > 0) {
ret = 0;
dval = value;
} else {
// Make room for the minus sign, and proceed as if positive.
ret = 1;
dval = -double(value);
}
ret += ceil(log10(dval+1.0));
return ret;
}
I tested this function for the whole range of int
in g++ 9.3.0 for x86-64.

The first part is simple:
@property
def x(self): ...
is the same as
def x(self): ...
x = property(x)
property
with just a getter.The next step would be to extend this property with a setter and a deleter. And this happens with the appropriate methods:
@x.setter
def x(self, value): ...
returns a new property which inherits everything from the old x
plus the given setter.
x.deleter
works the same way.
From the API (http://msdn.microsoft.com/en-us/library/system.datetime_members(VS.71).aspx) it does not seem it can show the name of the time zone used.
You can't do this, which is by design. The Django framework authors intended a strict separation of presentation code from data logic. Filtering models is data logic, and outputting HTML is presentation logic.
So you have several options. The easiest is to do the filtering, then pass the result to render_to_response
. Or you could write a method in your model so that you can say {% for object in data.filtered_set %}
. Finally, you could write your own template tag, although in this specific case I would advise against that.
Here is what you should do in the CSS style, on the main div

# Print the shell task's stdout.
- debug: msg={{ ps.stdout }}

What is X
? If it is a 2D-array, how can you then compare its row to a number: i < 3
?
EDIT after OP's comment:
A = array([[0, 1, 2], [0, 2, 0]])
X = array([[0, 1, 2], [1, 2, 0], [2, 1, 2], [3, 2, 0]])
add to A
all rows from X
where the first element < 3
:
import numpy as np
A = np.vstack((A, X[X[:,0] < 3]))
# returns:
array([[0, 1, 2],
[0, 2, 0],
[0, 1, 2],
[1, 2, 0],
[2, 1, 2]])

SimpleDateFormat
is great, just note that HH
is different from hh
when working with hours. HH
will return 24 hour based hours and hh will return 12 hour based hours.
For example, the following will return 12 hour time:
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm aa");
While this will return 24 hour time:
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
Suppose you have these buttons on page like :
<input type="submit" class="byBtn" disabled="disabled" value="Change"/>
<input type="submit" class="byBtn" disabled="disabled" value="Change"/>
<input type="submit" class="byBtn" disabled="disabled" value="Change"/>
<input type="submit" class="byBtn" disabled="disabled" value="Change"/>
<input type="submit" class="byBtn" disabled="disabled" value="Change"/>
<input type="submit"value="Enable All" onclick="change()"/>
The js code:
function change(){
var toenable = document.querySelectorAll(".byBtn");
for (var k in toenable){
toenable[k].removeAttribute("disabled");
}
}
The OVER
clause is powerful in that you can have aggregates over different ranges ("windowing"), whether you use a GROUP BY
or not
Example: get count per SalesOrderID
and count of all
SELECT
SalesOrderID, ProductID, OrderQty
,COUNT(OrderQty) AS 'Count'
,COUNT(*) OVER () AS 'CountAll'
FROM Sales.SalesOrderDetail
WHERE
SalesOrderID IN(43659,43664)
GROUP BY
SalesOrderID, ProductID, OrderQty
Get different COUNT
s, no GROUP BY
SELECT
SalesOrderID, ProductID, OrderQty
,COUNT(OrderQty) OVER(PARTITION BY SalesOrderID) AS 'CountQtyPerOrder'
,COUNT(OrderQty) OVER(PARTITION BY ProductID) AS 'CountQtyPerProduct',
,COUNT(*) OVER () AS 'CountAllAgain'
FROM Sales.SalesOrderDetail
WHERE
SalesOrderID IN(43659,43664)

ngAfterViewInit() {
this.rd.invokeElementMethod(this.el.nativeElement,'focus');
}
Please note from Angular v4.0.0-rc.3 (2017-03-10) few things have been changed.
Since Angular team will deprecate invokeElementMethod
, above code no longer can be used.
BREAKING CHANGES
since 4.0 rc.1:
rename RendererV2 to Renderer2
rename RendererTypeV2 to RendererType2
rename RendererFactoryV2 to RendererFactory2
import {ElementRef,Renderer2} from '@angular/core';
@ViewChild('someVar') el:ElementRef;
constructor(private rd: Renderer2) {}
ngAfterViewInit() {
console.log(this.rd);
this.el.nativeElement.focus(); //<<<=====same as oldest way
}
console.log(this.rd)
will give you following methods and you can see now invokeElementMethod
is not there. Attaching img as yet it is not documented.
NOTE: You can use following methods of Rendere2
with/without ViewChild variable to do so many things.
Using Path
is the recommended way since Python 3:
from pathlib import Path
print("File Path:", Path(__file__).absolute())
print("Directory Path:", Path().absolute()) # Directory of current working directory, not __file__
Documentation: pathlib
Note: If using Jupyter Notebook, __file__
doesn't return expected value, so Path().absolute()
has to be used.

Your problem is you have the b
in the open
flag.
The flag rt
(read, text) is the default, so, using the context manager, simply do this:
with open('sample.csv') as ifile:
read = csv.reader(ifile)
for row in read:
print (row)
The context manager means you don't need generic error handling (without which you may get stuck with the file open, especially in an interpreter), because it will automatically close the file on an error, or on exiting the context.
The above is the same as:
with open('sample.csv', 'r') as ifile:
...
or
with open('sample.csv', 'rt') as ifile:
...
This solved it when none of the other examples did:
$('#myTab a').click(function (e) {
e.preventDefault();
$(this).tab('show');
});

When console.log(this.ev)
is executed after this.fetchEvent();
, this doesn't mean the fetchEvent()
call is done, this only means that it is scheduled. When console.log(this.ev)
is executed, the call to the server is not even made and of course has not yet returned a value.
Change fetchEvent()
to return a Promise
fetchEvent(){
return this._apiService.get.event(this.eventId).then(event => {
this.ev = event;
console.log(event); // Has a value
console.log(this.ev); // Has a value
});
}
change ngOnInit()
to wait for the Promise
to complete
ngOnInit() {
this.fetchEvent().then(() =>
console.log(this.ev)); // Now has value;
}
This actually won't buy you much for your use case.
My suggestion: Wrap your entire template in an <div *ngIf="isDataAvailable"> (template content) </div>
and in ngOnInit()
isDataAvailable:boolean = false;
ngOnInit() {
this.fetchEvent().then(() =>
this.isDataAvailable = true); // Now has value;
}
Python 3 ints do not have a maximum.
If your purpose is to determine the maximum size of an int in C when compiled the same way Python was, you can use the struct module to find out:
>>> import struct
>>> platform_c_maxint = 2 ** (struct.Struct('i').size * 8 - 1) - 1
If you are curious about the internal implementation details of Python 3 int objects, Look at sys.int_info
for bits per digit and digit size details. No normal program should care about these.

git blame -L 10,+1 fe25b6d^ -- src/options.cpp
You can specify a revision for git blame to look back starting from (instead of the default of HEAD
); fe25b6d^
is the parent of fe25b6d
.
Edit: New to Git 2.23, we have the --ignore-rev
option added to git blame
:
git blame --ignore-rev fe25b6d
While this doesn't answer OP's question of giving the stack of commits (you'll use git log
for that, as per the other answer), it is a better way of this solution, as you won't potentially misblame the other lines.

One table for layout wouldn't be that bad. But you can't get the layout you need with just one table most of the time. Pretty soon you have 2 or three nested tables. This becomes very cumbersome.
It IS a LOT harder to read. That's not up to opinion. There's just more nested tags with no identifying marks on them.
Separating content from presentation is a good thing because it allows you to focus on what you're doing. Mixing the two leads to bloated pages that are hard to read.
CSS for styles allows your browser to cache the files and subsequent requests are much faster. This is HUGE.
Tables lock you into a design. Sure, not everyone needs the flexibility of CSS Zen Garden, but I've never worked on a site where I didn't need to change the design a little bit here and there. It's much easier with CSS.
Tables are hard to style. You don't have very much flexibility with them (i.e. you still need to add HTML attributes to fully control a table's styles)
I haven't used tables for non-tabular data in probably 4 years. I haven't looked back.
I'd really like to suggest reading CSS Mastery by Andy Budd. It's fantastic.

@TempCustomer
FROM
Customer
WHERE
CustomerId = @CustomerId"
Which means creating a new @tempCustomer
tablevariable and inserting data FROM Customer. You had already declared it above so no need of again declaring. Better to go with
INSERT INTO @tempCustomer SELECT * FROM Customer
Note: This is not a duplicate, because the OP is aware that the image from cv2.imread
is in BGR format (unlike the suggested duplicate question that assumed it was RGB hence the provided answers only address that issue)
To illustrate, I've opened up this same color JPEG image:
once using the conversion
img = cv2.imread(path)
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
and another by loading it in gray scale mode
img_gray_mode = cv2.imread(path, cv2.IMREAD_GRAYSCALE)
Like you've documented, the diff between the two images is not perfectly 0, I can see diff pixels in towards the left and the bottom
I've summed up the diff too to see
import numpy as np
np.sum(diff)
# I got 6143, on a 494 x 750 image
I tried all cv2.imread()
modes
Among all the IMREAD_
modes for cv2.imread()
, only IMREAD_COLOR
and IMREAD_ANYCOLOR
can be converted using COLOR_BGR2GRAY
, and both of them gave me the same diff against the image opened in IMREAD_GRAYSCALE
The difference doesn't seem that big. My guess is comes from the differences in the numeric calculations in the two methods (loading grayscale vs conversion to grayscale)
Naturally what you want to avoid is fine tuning your code on a particular version of the image just to find out it was suboptimal for images coming from a different source.
In brief, let's not mix the versions and types in the processing pipeline.
So I'd keep the image sources homogenous, e.g. if you have capturing the image from a video camera in BGR, then I'd use BGR as the source, and do the BGR to grayscale conversion cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
Vice versa if my ultimate source is grayscale then I'd open the files and the video capture in gray scale cv2.imread(path, cv2.IMREAD_GRAYSCALE)
$result = ['5' => 'cherry', '7' => 'apple'];
array_multisort($result, SORT_ASC);
print_r($result);
Array ( [0] => apple [1] => cherry )
//...
array_multisort($result, SORT_DESC);
//...
Array ( [0] => cherry [1] => apple )
Can this code be simplified in one if test instead two?
nil
and ''
are different values. If you need to test that s
is neither, IMO you should just compare against both, because it makes your intent the most clear.
That and a few alternatives, with their generated bytecode:
if not foo or foo == '' then end
GETGLOBAL 0 -1 ; foo
TEST 0 0 0
JMP 3 ; to 7
GETGLOBAL 0 -1 ; foo
EQ 0 0 -2 ; - ""
JMP 0 ; to 7
if foo == nil or foo == '' then end
GETGLOBAL 0 -1 ; foo
EQ 1 0 -2 ; - nil
JMP 3 ; to 7
GETGLOBAL 0 -1 ; foo
EQ 0 0 -3 ; - ""
JMP 0 ; to 7
if (foo or '') == '' then end
GETGLOBAL 0 -1 ; foo
TEST 0 0 1
JMP 1 ; to 5
LOADK 0 -2 ; ""
EQ 0 0 -2 ; - ""
JMP 0 ; to 7
The second is fastest in Lua 5.1 and 5.2 (on my machine anyway), but difference is tiny. I'd go with the first for clarity's sake.
I wouldn't use a List in the first places as an EnumSet is more approriate but you can do
List<Something> somethingList = Arrays.asList(Something.values());
or
List<Something> somethingList =
new ArrayList<Something>(EnumSet.allOf(Something.class));
In a production environment you want your app to be started again on a machine restart etc, creating a /etc/init.d/ script and linking to the appropriate runlevel to start and stop it is the correct approach. Spring Boot will not extend to covering this as it is a operating system specific setup and the are tonnes of other options, do you want it running in a chroot jail, does it need to stop / start before some other software etc.
I noticed that you can also get errors if you don't specify the angles correctly, even when using glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z))
you still might run into problems. The fix I found for this was specifying the type as glm::rotate(Model, (glm::mediump_float)90, glm::vec3(x, y, z))
instead of just saying glm::rotate(Model, 90, glm::vec3(x, y, z))
Or just write the second argument, the angle in radians (previously in degrees), as a float with no cast needed such as in:
glm::mat4 rotationMatrix = glm::rotate(glm::mat4(1.0f), 3.14f, glm::vec3(1.0));
You can add glm::radians() if you want to keep using degrees. And add the includes:
#include "glm/glm.hpp"
#include "glm/gtc/matrix_transform.hpp"
If you want to place your address in google map then easy way to use following
Intent searchAddress = new Intent(Intent.ACTION_VIEW,Uri.parse("geo:0,0?q="+address));
startActivity(searchAddress);
OR
if you needed to get lat long from your address then use Google Place Api following
create a method that returns a JSONObject with the response of the HTTP Call like following
public static JSONObject getLocationInfo(String address) {
StringBuilder stringBuilder = new StringBuilder();
try {
address = address.replaceAll(" ","%20");
HttpPost httppost = new HttpPost("http://maps.google.com/maps/api/geocode/json?address=" + address + "&sensor=false");
HttpClient client = new DefaultHttpClient();
HttpResponse response;
stringBuilder = new StringBuilder();
response = client.execute(httppost);
HttpEntity entity = response.getEntity();
InputStream stream = entity.getContent();
int b;
while ((b = stream.read()) != -1) {
stringBuilder.append((char) b);
}
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
JSONObject jsonObject = new JSONObject();
try {
jsonObject = new JSONObject(stringBuilder.toString());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return jsonObject;
}
now pass that JSONObject to getLatLong() method like following
public static boolean getLatLong(JSONObject jsonObject) {
try {
longitute = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
.getJSONObject("geometry").getJSONObject("location")
.getDouble("lng");
latitude = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
.getJSONObject("geometry").getJSONObject("location")
.getDouble("lat");
} catch (JSONException e) {
return false;
}
return true;
}
I hope this helps to you nd others..!! Thank you..!!
This format works, but it doesn't seem to be an official way of doing so
http://maps.google.com/maps?q=loc:36.26577,-92.54324
Also you may want to take a look at this. They have a few answers and seem to indicate that this is the new method:

@Joel's answer is pretty close, but it will fail in the following cases:
// Whitespace strings:
IsNumeric(' ') == true;
IsNumeric('\t\t') == true;
IsNumeric('\n\r') == true;
// Number literals:
IsNumeric(-1) == false;
IsNumeric(0) == false;
IsNumeric(1.1) == false;
IsNumeric(8e5) == false;
Some time ago I had to implement an IsNumeric
function, to find out if a variable contained a numeric value, regardless of its type, it could be a String
containing a numeric value (I had to consider also exponential notation, etc.), a Number
object, virtually anything could be passed to that function, I couldn't make any type assumptions, taking care of type coercion (eg. +true == 1;
but true
shouldn't be considered as "numeric"
).
I think is worth sharing this set of +30 unit tests made to numerous function implementations, and also share the one that passes all my tests:
function isNumeric(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
P.S. isNaN & isFinite have a confusing behavior due to forced conversion to number. In ES6, Number.isNaN & Number.isFinite would fix these issues. Keep that in mind when using them.
Update : Here's how jQuery does it now (2.2-stable):
isNumeric: function(obj) {
var realStringObj = obj && obj.toString();
return !jQuery.isArray(obj) && (realStringObj - parseFloat(realStringObj) + 1) >= 0;
}
Update : Angular 4.3:
export function isNumeric(value: any): boolean {
return !isNaN(value - parseFloat(value));
}
In addition to answer of @jww, I would like to say that the configuration in openssl-ca.cnf,
default_days = 1000 # How long to certify for
defines the default number of days the certificate signed by this root-ca will be valid. To set the validity of root-ca itself you should use '-days n' option in:
openssl req -x509 -days 3000 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM
Failing to do so, your root-ca will be valid for only the default one month and any certificate signed by this root CA will also have validity of one month.
The issue is two-fold:
As a prerequisite (as of August, 2016), you need to link an AdSense account and then turn on monetization in your YouTube channel. It's a painful change that broke a lot of live streams.
You will need to use the following URL format for the embed:
<iframe width="560" height="315" src="https://www.youtube.com/embed/live_stream?channel=CHANNEL_ID&autoplay=1" frameborder="0" allowfullscreen></iframe>
The &autoplay=1
is not necessary, but I like to include it. Change CHANNEL
to your channel's ID. One thing to note is that WordPress may reformat the URL once you commit your change. Therefore, you'll need a plugin that allows you to use raw code and not have it override. Using a custom PHP code plugin can help and you would just echo the code like so:
<?php echo '<iframe width="560" height="315" src="https://www.youtube.com/embed/live_stream?channel=CHANNEL_ID&autoplay=1" frameborder="0" allowfullscreen></iframe>'; ?>
Let me know if that worked for you!
To set all FormGroup values use, setValue:
this.myFormGroup.setValue({
formControlName1: myValue1,
formControlName2: myValue2
});
To set only some values, use patchValue:
this.myFormGroup.patchValue({
formControlName1: myValue1,
// formControlName2: myValue2 (can be omitted)
});
With this second technique, not all values need to be supplied and fields whos values were not set will not be affected.
Right, but as long as you use ASCII characters even a multibyte character set would still give a limitation of exactly 30 characters... so unless you want to put hearts and smiling cats in you're DB names your fine...
Specify complete path and grant proper permission to scriptfile. I tried following script file to run through cron:
#!/bin/bash
/bin/mkdir /scratch/ofsaaweb/CHEF_FICHOME/ficdb/bin/crondir
And crontab command is
* * * * * /bin/bash /scratch/ofsaaweb/CHEF_FICHOME/ficdb/bin/test.sh
It worked for me.
Thought of adding an answer for Angular 8:
For looping you can do:
<ng-container *ngFor="let item of BATCH_FILE_HEADERS | keyvalue: keepOriginalOrder">
<th nxHeaderCell>{{'upload.bulk.headings.'+item.key |translate}}</th>
</ng-container>
Also if you need the above array to keep the original order then declare this inside your class:
public keepOriginalOrder = (a, b) => a.key;
I also had this problem with another style of implementation but I forgot where I got it since it was 2 years ago.
static string sha256(string randomString)
{
var crypt = new SHA256Managed();
string hash = String.Empty;
byte[] crypto = crypt.ComputeHash(Encoding.ASCII.GetBytes(randomString));
foreach (byte theByte in crypto)
{
hash += theByte.ToString("x2");
}
return hash;
}
When I input something like abcdefghi2013
for some reason it gives different results and results in errors in my login module.
Then I tried modifying the code the same way as suggested by Quuxplusone and changed the encoding from ASCII
to UTF8
then it finally worked!
static string sha256(string randomString)
{
var crypt = new System.Security.Cryptography.SHA256Managed();
var hash = new System.Text.StringBuilder();
byte[] crypto = crypt.ComputeHash(Encoding.UTF8.GetBytes(randomString));
foreach (byte theByte in crypto)
{
hash.Append(theByte.ToString("x2"));
}
return hash.ToString();
}
Thanks again Quuxplusone for the wonderful and detailed answer! :)
Or you can use an alternative:
https://github.com/kint-php/kint
It works with zero set up and has much more features than Xdebug's var_dump anyway. To bypass the nested limit on the fly with Kint, just use
+d( $variable ); // append `+` to the dump call
Use a credential store.
For Git 2.11+ on OS X and Linux, use Git's built in credential store:
git config --global credential.helper libsecret
For msysgit 1.7.9+ on Windows:
git config --global credential.helper wincred
For Git 1.7.9+ on OS X use:
git config --global credential.helper osxkeychain
First things is this is only for advanced developers persons Who all are now beginner to php dont use this function if you are using the huge project in core php use this function
function displayAllRecords($serverName, $userName, $password, $databaseName,$sqlQuery='')
{
$databaseConnectionQuery = mysqli_connect($serverName, $userName, $password, $databaseName);
if($databaseConnectionQuery === false)
{

return false;
}
$resultQuery = mysqli_query($databaseConnectionQuery,$sqlQuery);
$fetchFields = mysqli_fetch_fields($resultQuery);
$fetchValues = mysqli_fetch_fields($resultQuery);
if (mysqli_num_rows($resultQuery) > 0)
{
echo "<table class='table'>";
echo "<tr>";
foreach ($fetchFields as $fetchedField)
{
echo "<td>";
echo "<b>" . $fetchedField->name . "<b></a>";
echo "</td>";
}
echo "</tr>";
while($totalRows = mysqli_fetch_array($resultQuery))
{
echo "<tr>";
for($eachRecord = 0; $eachRecord < count($fetchValues);$eachRecord++)
{
echo "<td>";
echo $totalRows[$eachRecord];
echo "</td>";
}
echo "<td><a href=''><button>Edit</button></a></td>";
echo "<td><a href=''><button>Delete</button></a></td>";
echo "</tr>";
}
echo "</table>";
}
else
{
echo "No Records Found in";
}
}
All set now Pass the arguments as For Example
$queryStatment = "SELECT * From USERS "; $testing = displayAllRecords('localhost','root','root@123','email',$queryStatment); echo $testing;
Here
localhost
indicates Name of the host
,
root
indicates the username for database
root@123
indicates the password for the database
$queryStatment
for generating Query
hope it helps
by creating an absolute-positioned link inside relative-positioned div.. You need set the link width & height as button dimensions, and left&top coordinates for the left-top corner of button within the wrapping div.
<div style="position:relative">
<img src="" width="??" height="??" />
<a href="#" style="display:block; width:247px; height:66px; position:absolute; left: 48px; top: 275px;"></a>
</div>
ExecutorService.invokeAll()
does it for you.
ExecutorService taskExecutor = Executors.newFixedThreadPool(4);
List<Callable<?>> tasks; // your tasks
// invokeAll() returns when all tasks are complete
List<Future<?>> futures = taskExecutor.invokeAll(tasks);
Correct way (if you are not trying to reset the value of the hidden_field input) is:
f.hidden_field :method, :value => value_of_the_hidden_field_as_it_comes_through_in_your_form
Where :method
is the method that when called on the object results in the value you want
So following the example above:
= simple_form_for @movie do |f|
= f.hidden :title, "some value"
= f.button :submit
The code used in the example will reset the value (:title) of @movie being passed by the form. If you need to access the value (:title) of a movie, instead of resetting it, do this:
= simple_form_for @movie do |f|
= f.hidden :title, :value => params[:movie][:title]
= f.button :submit
Again only use my answer is you do not want to reset the value submitted by the user.
I hope this makes sense.
Just move to the new branch. The uncommited changes get carried over.

Professional Excel Development by Stephen Bullen describes how to register UDFs, which allows a description to appear in the Function Arguments dialog:

To show the Function Arguments dialog, type the function name and press CtrlA. Alternatively, click the "fx" symbol in the formula bar:
If I understand the situation correctly, you are just passing json data through the http body, instead of application/x-www-form-urlencoded
data.
You can fetch this data with this snippet:
$request_body = file_get_contents('php://input');
If you are passing json, then you can do:
$data = json_decode($request_body);
$data
then contains the json data is php array.
php://input
is a so called wrapper.
php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".
I was looking for a different problem and came across this, so I will add my solution to a related problem: comparing two Maps.
// make a copy of the data
Map<String,String> a = new HashMap<String,String>(actual);
Map<String,String> e = new HashMap<String,String>(expected);
// check *every* expected value
for(Map.Entry<String, String> val : e.entrySet()){
// check for presence
if(!a.containsKey(val.getKey())){
System.out.println(String.format("Did not find expected value: %s", val.getKey()));
}
// check for equality
else{
if(0 != a.get(val.getKey()).compareTo(val.getValue())){
System.out.println(String.format("Value does not match expected: %s", val.getValue()));
}
// we have found the item, so remove it
// from future consideration. While it
// doesn't affect Java Maps, other types of sets
// may contain duplicates, this will flag those
// duplicates.
a.remove(val.getKey());
}
}
// check to see that we did not receive extra values
for(Map.Entry<String,String> val : a.entrySet()){
System.out.println(String.format("Found unexpected value: %s", val.getKey()));
}
It works on the same principle as the other solutions but also compares not only that values are present, but that they contain the same value. Mostly I've used this in accounting software when comparing data from two sources (Employee and Manager entered values match; Customer and Corporate transactions match; ... etc)
=
can be used when the subquery returns only 1 value.
When subquery returns more than 1 value, you will have to use IN
:
select *
from table
where id IN (multiple row query);
For example:
SELECT *
FROM Students
WHERE Marks = (SELECT MAX(Marks) FROM Students) --Subquery returns only 1 value
SELECT *
FROM Students
WHERE Marks IN
(SELECT Marks
FROM Students
ORDER BY Marks DESC
LIMIT 10) --Subquery returns 10 values
add to your qmake file
QMAKE_CXXFLAGS+= -std=c++11
QMAKE_LFLAGS += -std=c++11
I though I'd add one more way. In my case I supply this to com.hazelcast.config.XmlConfigBuilder
which only needs java.util.Properties
to resolve some properties inside the Hazelcast XML configuration file, i.e. it only calls getProperty(String)
method. So, this allowed me to do what I needed:
@RequiredArgsConstructor
public class SpringReadOnlyProperties extends Properties {
private final org.springframework.core.env.Environment delegate;
@Override
public String getProperty(String key) {
return delegate.getProperty(key);
}
@Override
public String getProperty(String key, String defaultValue) {
return delegate.getProperty(key, defaultValue);
}
@Override
public synchronized String toString() {
return getClass().getName() + "{" + delegate + "}";
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
if (!super.equals(o)) return false;
SpringReadOnlyProperties that = (SpringReadOnlyProperties) o;
return delegate.equals(that.delegate);
}
@Override
public int hashCode() {
return Objects.hash(super.hashCode(), delegate);
}
private void throwException() {
throw new RuntimeException("This method is not supported");
}
//all methods below throw the exception
* override all methods *
}
P.S. I ended up not using this specifically for Hazelcast because it only resolves properties for XML file but not at runtime. Since I also use Spring, I decided to go with a custom org.springframework.cache.interceptor.AbstractCacheResolver#getCacheNames
. This resolves properties for both situations, at least if you use properties in cache names.
You need to adjust with the .span

The
||
operator is "concatenate" - it joins together the two strings of its operands.
From http://www.sqlite.org/lang_expr.html
For padding, the seemingly-cheater way I've used is to start with your target string, say '0000', concatenate '0000423', then substr(result, -4, 4) for '0423'.
Update: Looks like there is no native implementation of "lpad" or "rpad" in SQLite, but you can follow along (basically what I proposed) here: http://verysimple.com/2010/01/12/sqlite-lpad-rpad-function/
-- the statement below is almost the same as
-- select lpad(mycolumn,'0',10) from mytable
select substr('0000000000' || mycolumn, -10, 10) from mytable
-- the statement below is almost the same as
-- select rpad(mycolumn,'0',10) from mytable
select substr(mycolumn || '0000000000', 1, 10) from mytable
Here's how it looks:
SELECT col1 || '-' || substr('00'||col2, -2, 2) || '-' || substr('0000'||col3, -4, 4)
it yields
"A-01-0001"
"A-01-0002"
"A-12-0002"
"C-13-0002"
"B-11-0002"
Take a look at this question and this question for some good answers on C++ object instantiation.
This basic idea is that objects instantiated on the heap (using new) need to be cleaned up manually, those instantiated on the stack (without new) are automatically cleaned up when they go out of scope.
void SomeFunc()
{
Point p1 = Point(0,0);
} // p1 is automatically freed
void SomeFunc2()
{
Point *p1 = new Point(0,0);
delete p1; // p1 is leaked unless it gets deleted
}
You need to remove the /var/lib/mysql folder. Also, purge when you remove the packages (I'm told this helps).
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo rm -rf /var/lib/mysql
I was encountering similar issues. The second line got rid of my issues and allowed me to set up MySql from scratch. Hopefully it helps you too!
In Eclipse Kepler it is very easy to generate Web Service Client classes,You can achieve this by following steps .
RightClick on any Project->Create New Other ->Web Services->Web Service Client->Then paste the wsdl url(or location) in Service Definition->Next->Finish
You will see the generated classes are inside your src folder.
NOTE :Without eclipse also you can generate client classes from wsdl file by using wsimport command utility which ships with JDK.

Check your SMTP settings in your php.ini file. Your host should have some documentation about what credentials to use. Perhaps you can check your error log file, it might have more information available.
Use atof()
But this is deprecated, use this instead:
const char* flt = "4.0800";
float f;
sscanf(flt, "%f", &f);
http://www.cplusplus.com/reference/clibrary/cstdlib/atof/
atof()
returns 0
for both failure and on conversion of 0.0
, best to not use it.
This provides you the code example on sorting map. Basically this is what they provide:
var keys []int
for k := range myMap {
keys = append(keys, k)
}
sort.Ints(keys)
// Benchmark1-8 2863149 374 ns/op 152 B/op 5 allocs/op
and this is what I would suggest using instead:
keys := make([]int, 0, len(myMap))
for k := range myMap {
keys = append(keys, k)
}
sort.Ints(keys)
// Benchmark2-8 5320446 230 ns/op 80 B/op 2 allocs/op
Full code can be found in this Go Playground.
for single array Item use reset($item)
I also had the same issue.Make a directory in dbpath.In my case there wasn't a directory in /data/db .So i created one.Now its working.Make sure to give permission to that directory.
For fpdf to work properly, there cannot be any output at all beside what fpdf generates. For example, this will work:
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
While this will not (note the leading space before the opening <?
tag)
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
Also, this will not work either (the echo
will break it):
<?php
echo "About to create pdf";
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
I'm not sure about the drupal side of things, but I know that absolutely zero non-fpdf output is a requirement for fpdf to work.
add ob_start ();
at the top and at the end add ob_end_flush();
<?php
ob_start();

$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
ob_end_flush();
?>
give me an error as below:
FPDF error: Some data has already been output, can't send PDF
to over come this error:
go to fpdf.php
in that,goto line number 996
function Output($name='', $dest='')
after that make changes like this:

In my case i had set:
ini_set('display_errors', 'on');
error_reporting(E_ALL | E_STRICT);
When i made the request to generate the report, some warnings were displayed in the browser (like the usage of deprecated functions).
Turning off
the display_errors
option, the report was generated successfully.
I had to change the SecurityMode to Message (WSHttpBinding), before it worked. i.e.
_wcf = new ServiceRequestClient(new WSHttpBinding(SecurityMode.Message),
new EndpointAddress(_wcfRequestServerAddress));
$total=0;
foreach($group as $key=>$value)
{
echo $key. " = " .$value. "<br>";
$total+= $value;
}
echo $total;
select charindex( 'Express',@@version)
if this value is 0 is not a express edition

You should use querySelectorAll
. It returns NodeList, however querySelector
returns only the first found element:
var deleteLink = document.querySelectorAll('.delete');
Then you would loop:
for (var i = 0; i < deleteLink.length; i++) {
deleteLink[i].addEventListener('click', function(event) {
if (!confirm("sure u want to delete " + this.title)) {
event.preventDefault();
}
});
}
Also you should preventDefault only if confirm === false
.
It's also worth noting that return false/true
is only useful for event handlers bound with onclick = function() {...}
. For addEventListening
you should use event.preventDefault()
.
Demo: http://jsfiddle.net/Rc7jL/3/
ES6 version
You can make it a little cleaner (and safer closure-in-loop wise) by using Array.prototype.forEach iteration instead of for-loop:
var deleteLinks = document.querySelectorAll('.delete');
Array.from(deleteLinks).forEach(link => {
link.addEventListener('click', function(event) {
if (!confirm(`sure u want to delete ${this.title}`)) {
event.preventDefault();
}
});
});
Example above uses Array.from and template strings from ES2015 standard.
If you want to reset the selected options
$('select option:selected').removeAttr('selected');
If you actually want to remove the options (although I don't think you mean this).
$('select').empty();
Substitute select
for the most appropriate selector in your case (this may be by id or by CSS class). Using as is will reset all <select>
elements on the page
CodeIgniter has some error logging functions built in.
$config['log_threshold'] = 1;
log_message('error', 'Some variable did not contain a value.');
log_exceptions()
. You can do this yourself or use this. More info on extending the core hereSee http://www.codeigniter.com/user_guide/general/errors.html
It is a pity that substring
is not implemented in a way that handles short strings – like in other languages e.g. Python.
Ok, we cannot change that and have to consider this edge case every time we use substr
, instead of if-else clauses I would go for this shorter variant:
myText.substring(0, Math.min(6, myText.length()))
To avoid the boxing of KeyValuePair.Equals(object)
you can use a ValueTuple
.
if ((getResult.Key, getResult.Value) == default)
As per my understanding you want data in dictionary as shown below:
key1: value1-1,value1-2,value1-3....value100-1
key2: value2-1,value2-2,value2-3....value100-2
key3: value3-1,value3-2,value3-2....value100-3
for this you can use list for each dictionary keys:
case_list = {}
for entry in entries_list:
if key in case_list:
case_list[key1].append(value)
else:
case_list[key1] = [value]
Another option would be to simply use grepl
function:
df[grepl('er', df$name), ]
CO2[grepl('non', CO2$Treatment), ]
df <- data.frame(name = c('bob','robert','peter'),
id = c(1,2,3)
)
# name id
# 2 robert 2
# 3 peter 3
Example: say you have an 'image' you want to scale you will need a bufferedImage probably, and probably will be starting out with just 'Image' object. So this works I think... The AVATAR_SIZE is the target width we want our image to be:
Image imgData = image.getScaledInstance(Constants.AVATAR_SIZE, -1, Image.SCALE_SMOOTH);
BufferedImage bufferedImage = new BufferedImage(imgData.getWidth(null), imgData.getHeight(null), BufferedImage.TYPE_INT_RGB);
bufferedImage.getGraphics().drawImage(imgData, 0, 0, null);
document.querySelectorAll('data-foo')
to get list of all elements having attribute data-foo
If you want to get element with data attribute which is having some specific value e.g
<div data-foo="1"></div>
<div data-foo="2" ></div>
and I want to get div with data-foo set to "2"
document.querySelector('[data-foo="2"]')
But here comes the twist what if I want to match the data attirubte value with some variable's value like I want to get element if data-foo attribute is set to i
var i=2;
so you can dynamically select the element having specific data element using template literals
document.querySelector(`[data-foo="${i}"]`)
Note even if you don't write value in string it gets converted to string like if I write
<div data-foo=1></div>
and then inspect the element in Chrome developer tool the element will be shown as below
<div data-foo="1"></div>
You can also cross verify by writing below code in console
console.log(typeof document.querySelector(`[data-foo]="${i}"`).dataset('dataFoo'))
why I have written 'dataFoo' though the attribute is data-foo reason dataset properties are converted to camelCase properties

In modern browsers with modern javascript (>= 2015) you can add type="module"
to your script tag, and everything inside that script will execute after whole page loads. e.g:
<script type="module">
alert("runs after") // Whole page loads before this line execute
</script>
<script>
alert("runs before")
</script>
also older browsers will understand nomodule
attribute. Something like this:
<script nomodule>
alert("tuns after")
</script>
For more information you can visit javascript.info.
Xcode 7.0.1 and iOS 9.1 are incompatible. You will need to update your version of Xcode via the Mac app store.
If your iOS version is lower then the Xcode version on the other hand, you can change the deployment target for a lower version of iOS by going to the General Settings and under Deployment set your Deployment Target:
Xcode 7.1 does not include iOS 9.2 beta SDK. Upgraded to Xcode to 7.2 beta by downloading it from the Xcode website.

An arbitrary OAuth access token can't be used for authentication, because the meaning of the token is outside of the OAuth Core spec. It could be intended for a single use or narrow expiration window, or it could provide access which the user doesn't want to give. It's also opaque, and the OAuth consumer which obtained it might never have seen any type of user identifier.
An OAuth service provider and one or more consumers could easily use OAuth to provide a verifiable authentication token, and there are proposals and ideas to do this out there, but an arbitrary service provider speaking only OAuth Core can't provide this without other co-ordination with a consumer. The Google-specific AuthSubTokenInfo REST method, along with the user's identifier, is close, but it isn't suitable, either, since it could invalidate the token, or the token could be expired.
If your Google ID is an OpenId identifier, and your 'public interface' is either a web app or can call up the user's browser, then you should probably use Google's OpenID OP.
OpenID consists of just sending the user to the OP and getting a signed assertion back. The interaction is solely for the benefit of the RP. There is no long-lived token or other user-specific handle which could be used to indicate that a RP has successfully authenticated a user with an OP.
One way to verify a previous authentication against an OpenID identifier is to just perform authentication again, assuming the same user-agent is being used. The OP should be able to return a positive assertion without user interaction (by verifying a cookie or client cert, for example). The OP is free to require another user interaction, and probably will if the authentication request is coming from another domain (my OP gives me the option to re-authenticate this particular RP without interacting in the future). And in Google's case, the UI that the user went through to get the OAuth token might not use the same session identifier, so the user will have to re-authenticate. But in any case, you'll be able to assert the identity.
Yes, the function is querySelectorAll
(or querySelector
for a single element), which allows you to use CSS selectors to find elements.
document.querySelectorAll('[property]'); // All with attribute named "property"
document.querySelectorAll('[property="value"]'); // All with "property" set to "value" exactly.
(Complete list of attribute selectors on MDN.)
This finds all elements with the attribute property. It would be better to specify a tag name if possible:
document.querySelectorAll('span[property]');
You can work around this if necessary by looping through all the elements on the page to see whether they have the attribute set:
var withProperty = [],
els = document.getElementsByTagName('span'), // or '*' for all types of element
i = 0;
for (i = 0; i < els.length; i++) {
if (els[i].hasAttribute('property')) {
withProperty.push(els[i]);
}
}
Libraries such as jQuery handle this for you; it's probably a good idea to let them do the heavy lifting.
For anyone dealing with ancient browsers, note that querySelectorAll
was introduced to Internet Explorer in v8 (2009) and fully supported in IE9. All modern browsers support it.
You can pass in a pointer to a time_t
object that time will fill up with the current time (and the return value is the same one that you pointed to). If you pass in NULL
, it just ignores it and merely returns a new time_t
object that represents the current time.
Nb:time(&timer);
is equivalent to timer = time(NULL);
Installing requirements.txt file inside virtual env with Python 3:
I had the same issue. I was trying to install the requirements.txt file inside a virtual environment. I found the solution.
Initially, I created my virtualenv in this way:
virtualenv -p python3 myenv
Activate the environment using:
source myenv/bin/activate
Now I installed the requirements.txt file using:
pip3 install -r requirements.txt
Installation was successful and I was able to import the modules.

As mentioned in the excellent answer by janoside, you need to construct the JSON string and set it as a StringEntity
.
To construct the JSON string, you can use any library or method you are comfortable with. Jackson library is one easy example:
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.StringEntity;
ObjectMapper mapper = new ObjectMapper();
ObjectNode node = mapper.createObjectNode();
node.put("name", "value"); // repeat as needed
String JSON_STRING = node.toString();
postMethod.setEntity(new StringEntity(JSON_STRING, ContentType.APPLICATION_JSON));
I have had the same problem.
In my case, since I have the original repository in my local machine, I have made a copy in a new folder without any hidden file (.git, .gitignore).
Finally I have added the .gitignore file to the new created folder.
Then I have created and added the new repository from the local path (in my case using GitHub Desktop).
We show up two functions that prints a SINGLE character to binary.
void printbinchar(char character)
{
char output[9];
itoa(character, output, 2);
printf("%s\n", output);
}
printbinchar(10) will write into the console
1010
itoa is a library function that converts a single integer value to a string with the specified base. For example... itoa(1341, output, 10) will write in output string "1341". And of course itoa(9, output, 2) will write in the output string "1001".
The next function will print into the standard output the full binary representation of a character, that is, it will print all 8 bits, also if the higher bits are zero.
void printbincharpad(char c)
{
for (int i = 7; i >= 0; --i)
{
putchar( (c & (1 << i)) ? '1' : '0' );
}
putchar('\n');
}
printbincharpad(10) will write into the console
00001010
Now i present a function that prints out an entire string (without last null character).
void printstringasbinary(char* s)
{
// A small 9 characters buffer we use to perform the conversion
char output[9];
// Until the first character pointed by s is not a null character
// that indicates end of string...
while (*s)
{
// Convert the first character of the string to binary using itoa.
// Characters in c are just 8 bit integers, at least, in noawdays computers.
itoa(*s, output, 2);
// print out our string and let's write a new line.
puts(output);
// we advance our string by one character,
// If our original string was "ABC" now we are pointing at "BC".
++s;
}
}
Consider however that itoa don't adds padding zeroes, so printstringasbinary("AB1") will print something like:
1000001
1000010
110001
