Interestingly, http://maps.apple.com
links will open directly in Apple Maps on an iOS device, or redirect to Google Maps otherwise (which is then intercepted on an Android device), so you can craft a careful URL that will do the right thing in both cases using an "Apple Maps" URL like:
http://maps.apple.com/?daddr=1600+Amphitheatre+Pkwy,+Mountain+View+CA
Alternatively, you can use a Google Maps url directly (without the /maps
URL component) to open directly in Google Maps on an Android device, or open in Google Maps' Mobile Web on an iOS device:
http://maps.google.com/?daddr=1+Infinite+Loop,+Cupertino+CA
For any Xamarin.iOS or Xamarin.Forms developers, additionally you will want to check the .csproj file (for the iOS project) and ensure that it contains references to the PNG's and not just the Asset Catalog i.e.

Here is a very slight improvement to user1387483's answer using an immediate function:
(function() {
$("*").on( 'touchstart', function() {
$(this).trigger('hover') ;
} ).on('touchend', function() {
$(this).trigger('hover') ;
} ) ;
})() ;
Also, I agree with Boz that this appears to be the "neatest, most compliant solution".
Since you installed a new OS you probably don't have any more of your private and public keys that you used to sign your app in to XCode before. You need to regenerate those keys on your machine by revoking your previous certificate and asking for a new one on the iOS development portal. As part of the process you will be asked to generate a Certificate Signing Request which is where you seem to have a problem.
You will find all you need there which consists of (from the official doc):
1.Open Keychain Access on your Mac (located in Applications/Utilities).
2.Open Preferences and click Certificates. Make sure both Online Certificate Status Protocol and Certificate Revocation List are set to Off.
3.Choose Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority.
Note: If you have a private key selected when you do this, the CSR won’t be accepted. Make sure no private key is selected. Enter your user email address and common name. Use the same address and name as you used to register in the iOS Developer Program. No CA Email Address is required.
4.Select the options “Saved to disk” and “Let me specify key pair information” and click Continue.
5.Specify a filename and click Save. (make sure to replace .certSigningRequest with .csr)
For the Key Size choose 2048 bits and for Algorithm choose RSA. Click Continue and the Certificate Assistant creates a CSR and saves the file to your specified location.
If you have a plist of devices (eg maintained by @Tib above in https://stackoverflow.com/a/17655825/849616) to handle it if Swift 3 you'd use:
extension UIDevice {
/// Fetches the information about the name of the device.
///
/// - Returns: Should return meaningful device name, if not found will return device system code.
public static func modelName() -> String {
let physicalName = deviceSystemCode()
if let deviceTypes = deviceTypes(), let modelName = deviceTypes[physicalName] as? String {
return modelName
}
return physicalName
}
}
private extension UIDevice {
/// Fetches from system the code of the device
static func deviceSystemCode() -> String {
var systemInfo = utsname()
uname(&systemInfo)
let machineMirror = Mirror(reflecting: systemInfo.machine)
let identifier = machineMirror.children.reduce("") { identifier, element in
guard let value = element.value as? Int8, value != 0 else { return identifier }
return identifier + String(UnicodeScalar(UInt8(value)))
}
return identifier
}
/// Fetches the plist entries from plist maintained in https://stackoverflow.com/a/17655825/849616
///
/// - Returns: A dictionary with pairs of deviceSystemCode <-> meaningfulDeviceName.
static func deviceTypes() -> NSDictionary? {
if let fileUrl = Bundle.main.url(forResource: "your plist name", withExtension: "plist"),
let configurationDictionary = NSDictionary(contentsOf: fileUrl) {
return configurationDictionary
}
return nil
}
}
Later you can call it using UIDevice.modelName()
.
Additional credits go to @Tib (for plist), @Aniruddh Joshi (for deviceSystemCode()
function).
You can also use this

}
If one will use TASK_BASIC_INFO_COUNT instead of MACH_TASK_BASIC_INFO, you will get

Add this code into the css file:
input {

This will help.
The following worked for me:
function changeOrientation(){
switch(window.orientation) {
case 0: // portrait, home bottom
case 180: // portrait, home top
alert("portrait H: "+$(window).height()+" W: "+$(window).width());
break;
case -90: // landscape, home left
case 90: // landscape, home right
alert("landscape H: "+$(window).height()+" W: "+$(window).width());
break;
}
}
window.onorientationchange = function() {
//Need at least 800 milliseconds
setTimeout(changeOrientation, 1000);
}
I needed the timeout because the value of window.orientation
does not update right away
Go to Build Settings, under Code Signing, set Code Signing Identity as iOS Developer & Provisioning Profile as Automatic.
Select your device (now visible) from drop down list and run your app.
If you uncheck "Build Active Architecture Only", then it will build all the valid architectures.
Update: This is no longer applicable as of Xcode 4 - follow Nick's instructions for Xcode 4 and later.
With plans to slowly retire the long-used Objective-C, Apple has introduced a new programming language, called Swift, for designing apps and applications to run on Apple iOS devices and Apple Macintosh computers.
Apple says: "Swift is a new programming language for iOS and OS X apps that builds on the best of C and Objective-C, without the constraints of C compatibility. Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works."
From iOS 13, can not find 'iPad', i use this js current-device, it work.
this core:
const iPadOS13Up = navigator.platform === 'MacIntel' && navigator.maxTouchPoints > 1
https://github.com/matthewhudson/current-device/blob/master/src/index.js#L55
you can see you die type : http://matthewhudson.github.io/current-device/
Here's a simpler solution that worked for me and which doesn't require the manual editing of the project file:
In Xcode, in the "Groups & Files" pane, expand "Targets" and double-click on your app's target. This brings up the Info pane for the target. In the "Build" section, check the "code signing" section for any old profiles and replace with the correct one.
Note that this is different from double-clicking on your project icon and changing the profile from there. Quite amazing :)

You can check GBDeviceInfo on GitHub, also available via CocoaPods. It provides simple API for detecting various properties with support of all latest devices:
[GBDeviceInfo deviceDetails].family == GBDeviceFamilyiPhone;
[GBDeviceInfo deviceDetails].model == GBDeviceModeliPhone6.

Here's an example of a function that accepts a callback
const sqk = (x: number, callback: ((_: number) => number)): number => {
// callback will receive a number and expected to return a number
return callback (x * x);
}
// here our callback will receive a number
sqk(5, function(x) {
console.log(x); // 25
return x; // we must return a number here
});
If you don't care about the return values of callbacks (most people don't know how to utilize them in any effective way), you can use void
const sqk = (x: number, callback: ((_: number) => void)): void => {
// callback will receive a number, we don't care what it returns
callback (x * x);
}
// here our callback will receive a number
sqk(5, function(x) {
console.log(x); // 25
// void
});
Note, the signature I used for the callback
parameter ...
const sqk = (x: number, callback: ((_: number) => number)): number
I would say this is a TypeScript deficiency because we are expected to provide a name for the callback parameters. In this case I used _
because it's not usable inside the sqk
function.
However, if you do this
// danger!! don't do this
const sqk = (x: number, callback: ((number) => number)): number
It's valid TypeScript, but it will interpreted as ...
// watch out! typescript will think it means ...
const sqk = (x: number, callback: ((number: any) => number)): number
Ie, TypeScript will think the parameter name is number
and the implied type is any
. This is obviously not what we intended, but alas, that is how TypeScript works.
So don't forget to provide the parameter names when typing your function parameters... stupid as it might seem.
Initializing the contents of a list like that isn't really what lists are for. Lists are designed to hold objects. If you want to map particular numbers to particular objects, consider using a key-value pair structure like a hash table or dictionary instead of a list.
Here, I summarize a few ways which may return different results to your question, so be careful:
# First assign your "id"s to an R object.
# Here's a hypothetical example:
id <- c("a","b","b","c","c","c","d","d","d","d")
#To return ALL MINUS ONE duplicated values:
id[duplicated(id)]
## [1] "b" "c" "c" "d" "d" "d"
#To return ALL duplicated values by specifying fromLast argument:
id[duplicated(id) | duplicated(id, fromLast=TRUE)]
## [1] "b" "b" "c" "c" "c" "d" "d" "d" "d"
#Yet another way to return ALL duplicated values, using %in% operator:
id[ id %in% id[duplicated(id)] ]
## [1] "b" "b" "c" "c" "c" "d" "d" "d" "d"
Hope these help. Good luck.
i came across a similar situation using booleans where I wanted to avoid calling b() if a was already false.
This worked for me:
a &= a && b()
I have had this problem several times and it can be usually resolved with a clean and rebuild as answered by many before me. But this time this would not fix it.
I use my cordova app to build 2 seperate apps that share majority of the same codebase and it drives off the config.xml. I could not build in end up because i had a space in my id.
com.company AppName
instead of:
com.company.AppName
If anyone is in there config as regular as me. This could be your problem, I also have 3 versions of each app. Live / Demo / Test - These all have different ids.
com.company.AppName.Test
Easy mistake to make, but even easier to overlook. Spent loads of time rebuilding, checking plugins, versioning etc. Where I should have checked my config. First Stop Next Time!
Above answer explains very well ..just to add one thing If you are using using eclipse use ctrl+shift+T and enter package structure of class (e.g. : gateway.smpp.PDUEventListener ), you will find all jars/projects where it's present. Remove unnecessary jars from classpath or add above in class path. Now it will pick up correct one.

Here's a complete solution for Swagger with Spring Security. We probably want to only enable Swagger in our development and QA environment and disable it in the production environment. So, I am using a property (prop.swagger.enabled
) as a flag to bypass spring security authentication for swagger-ui only in development/qa environment.
@Configuration
@EnableSwagger2
public class SwaggerConfiguration extends WebSecurityConfigurerAdapter implements WebMvcConfigurer {
@Value("${prop.swagger.enabled:false}")
private boolean enableSwagger;
@Bean
public Docket SwaggerConfig() {
return new Docket(DocumentationType.SWAGGER_2)
.enable(enableSwagger)
.select()
.apis(RequestHandlerSelectors.basePackage("com.your.controller"))
.paths(PathSelectors.any())
.build();
}
@Override
public void configure(WebSecurity web) throws Exception {
if (enableSwagger)
web.ignoring().antMatchers("/v2/api-docs",
"/configuration/ui",
"/swagger-resources/**",
"/configuration/security",
"/swagger-ui.html",
"/webjars/**");
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
if (enableSwagger) {
registry.addResourceHandler("swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
}
System.err.println("Someone is Restarting me...");
setVisible(false);
try {
Thread.sleep(600);
} catch (InterruptedException e1) {
e1.printStackTrace();
}
setVisible(true);
I guess you don't really want to stop the application, but to "Restart" it. For that, you could use this and add your "Reset" before the sleep and after the invisible window.

systemDateTest.setStringDate(simpleDateFormat.format(systemDateTest.getDate()));
System.out.println(systemDateTest.getStringDate());
}
public Date getDate() {
return new Date();
}
public String getStringDate() {
return stringDate;
}
public void setStringDate(String stringDate) {
this.stringDate = stringDate;
}
}
I instinctively read it as "different from". "!=" hits me milliseconds after.
The While statement will not execute until after form1 is closed - as it is outside the main message loop.
Remove it and change the first bit of code to:
private void button1_Click_1(object sender, EventArgs e)
{
if (richTextBox1.Text != null)
{
this.Visible=false;
Form2 form2 = new Form2();
form2.show();
}
else MessageBox.Show("Insert Attributes First !");
}
This is not the best way to achieve what you are looking to do though. Instead consider the Wizard design pattern.
Alternatively you could implement a custom ApplicationContext that handles the lifetime of both forms. An example to implement a splash screen is here, which should set you on the right path.

To run Tomcat8 you need to have JRE_HOME defined in Env Variable.
JAVA_HOME alone will not do even if correctly set.
JRE_HOME = C:\Program Files\Java\jdk1.8.0_77\jre
You should select the JRE that is inside SDK, i.e. one with your JDK(SDK) installation. In other words your JAVA_HOME + \jre
When compiling JDK is needed to support JSP, to compile Servlets which are generated from *.jsp files. Otherwise to run JRE is needed. So when you develop you need JAVA_HOME and when you deploy you need JRE_HOME.
Here's what actually worked for me, after guidance from answers here:

This doesn't seem to work with the Adobe Type library. As soon as it gets to Open, I get a 429 error. Acrobat works fine though...
try something like :
var focusout = false;
$("#Button1").click(function () {

$("#Text1").focusout(function () {
focusout = true;

I got this error when one of my properties that was required for the constructor was not public. Make sure all the parameters in the constructor go to properties that are public if this is the case:
using statements namespace someNamespace
public class ExampleClass {
//Properties - one is not visible to the class calling the constructor
public string Property1 { get; set; }
string Property2 { get; set; }
//Constructor
public ExampleClass(string property1, string property2)
{
this.Property1 = property1;
this.Property2 = property2; //this caused that error for me
}
}
If you want greater control you can use javascript rather than use the meta tag. This would allow you to have a visual of some kind, e.g. a countdown.
Here is a very basic approach using setTimeout()
<html>_x000D_
<body>_x000D_
<p>You will be redirected in 3 seconds</p>_x000D_

var timer = setTimeout(function() {_x000D_
window.location='http://example.com'_x000D_
}, 3000);_x000D_
</script>_x000D_
</body>_x000D_

This way worked for me:
adding the path that you like:
export PYTHONPATH=$PYTHONPATH:/path/you/want/to/add
checking: you can run 'export' cmd and check the output or you can check it using this cmd:
python -c "import sys; print(sys.path)"
plt.imshow
just finishes drawing a picture instead of printing it. If you want to print the picture, you just need to add plt.show
.
If you want to prevent all caching (e.g. force a reload when using the back button) you need:
no-cache for IE
no-store for Firefox
There's my information about this here:

Does this work?

Easy way to Fetch Single Record from MySQL Database by using PHP List
The SQL Query is SELECT user_name from user_table WHERE user_id = 6
The PHP Code for the above Query is
$sql_select = "";
$sql_select .= "SELECT ";
$sql_select .= " user_name ";
$sql_select .= "FROM user_table ";
$sql_select .= "WHERE user_id = 6" ;
$rs_id = mysql_query($sql_select, $link) or die(mysql_error());
list($userName) = mysql_fetch_row($rs_id);
Note: The List Concept should be applicable for Single Row Fetching not for Multiple Rows
In Swift 3.0
let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height
In older swift: Do something like this:
let screenSize: CGRect = UIScreen.mainScreen().bounds
then you can access the width and height like this:
let screenWidth = screenSize.width
let screenHeight = screenSize.height
if you want 75% of your screen's width you can go:
let screenWidth = screenSize.width * 0.75
Swift 4.0
// Screen width.
public var screenWidth: CGFloat {
return UIScreen.main.bounds.width
}
// Screen height.
public var screenHeight: CGFloat {
return UIScreen.main.bounds.height
}
In Swift 5.0
let screenSize: CGRect = UIScreen.main.bounds
Acked Unseen sample
Hi guys! Just some observations from what I just found in my capture:
On many occasions, the packet capture reports “ACKed segment that wasn't captured” on the client side, which alerts of the condition that the client PC has sent a data packet, the server acknowledges receipt of that packet, but the packet capture made on the client does not include the packet sent by the client
Initially, I thought it indicates a failure of the PC to record into the capture a packet it sends because “e.g., machine which is running Wireshark is slow” (https://osqa-ask.wireshark.org/questions/25593/tcp-previous-segment-not-captured-is-that-a-connectivity-issue)
However, then I noticed every time I see this “ACKed segment that wasn't captured” alert I can see a record of an “invalid” packet sent by the client PC
In the capture example above, frame 67795 sends an ACK for 10384
Even though wireshark reports Bogus IP length (0), frame 67795 is reported to have length 13194
To get all the values from a list of dictionaries, use the following code :
list = [{'text': 1, 'b': 2}, {'text': 3, 'd': 4}, {'text': 5, 'f': 6}]
subtitle=[]
for value in list:
subtitle.append(value['text'])
Completing the answer from Adam Boduch, this one takes into differences in properties
const differenceOfKeys = (...objects) =>
_.difference(...objects.map(obj => Object.keys(obj)));
const differenceObj = (a, b) =>
_.reduce(a, (result, value, key) => (
_.isEqual(value, b[key]) ? result : [...result, key]
), differenceOfKeys(b, a));
xhr.file = file;
; the file object is not supposed to be attached this way.xhr.send(file)
doesn't send the file. You have to use the FormData
object to wrap the file into a multipart/form-data
post data object:
var formData = new FormData();
formData.append("thefile", file);
xhr.send(formData);
After that, the file can be access in $_FILES['thefile']
(if you are using PHP).
Remember, MDC and Mozilla Hack demos are your best friends.
EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.
This is work for me in Chrome
<input type="text" name="product_title" class="form-control"
required placeholder="Product Name" value="" pattern="([A-z0-9À-ž\s]){2,}"
oninvalid="setCustomValidity('Please enter on Producut Name at least 2 characters long')" />

There are two uses. These are specially used more often in embedded development.
Compiler will not optimise the functions that uses variables that are defined with volatile keyword
Volatile is used to access exact memory locations in RAM, ROM, etc... This is used more often to control memory-mapped devices, access CPU registers and locate specific memory locations.
See examples with assembly listing. Re: Usage of C "volatile" Keyword in Embedded Development
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.
How about System.currentTimeMillis()
?
From the JavaDoc:
Returns: the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC
Java 8 introduces the java.time
framework, particularly the Instant
class which "...models a ... point on the time-line...":
long now = Instant.now().toEpochMilli();
Returns: the number of milliseconds since the epoch of 1970-01-01T00:00:00Z -- i.e. pretty much the same as above :-)

To add global settings you can access the file C:\users\user.name\mercurial.ini and add the section
[auth]
bb.prefix=https://bitbucket.org/zambezia/packagemanager
bb.username = $username
bb.password = $password
Hope this helps.
You can do something like
SELECT *
FROM (SELECT Fname FROM MyTbl ORDER BY Fname )
WHERE rownum = 1;
You could also use the analytic functions RANK and/or DENSE_RANK, but ROWNUM is probably the easiest.
You can customize the JsonSerializerSettings
by using the Formatters.JsonFormatter.SerializerSettings
property in the HttpConfiguration
object.
For example, you could do that in the Application_Start() method:
protected void Application_Start()
{
HttpConfiguration config = GlobalConfiguration.Configuration;
config.Formatters.JsonFormatter.SerializerSettings.Formatting =
Newtonsoft.Json.Formatting.Indented;
}
-First Move Your Code Files in side the "src" Folder
-Make sure your Main method is declared like the following
public class Main {
public static void main(String []args){
}
}
then:
and it should work
Your SELECT
statement isn't finding the data you're looking for. That is, there is no record in the ENROLLMENT
table with the given STUDENT_ID
and SECTION_ID
. You may want to try putting some DBMS_OUTPUT.PUT_LINE
statements before you run the query, printing the values of v_student_id
and v_section_id
. They may not be containing what you expect them to contain.
Does this work for you?
string1.indexOf(string2) >= 0
Edit: This may not be faster than a RegExp if the string2 contains repeated patterns. On some browsers, indexOf may be much slower than RegExp. See comments.
Edit 2: RegExp may be faster than indexOf when the strings are very long and/or contain repeated patterns. See comments and @Felix's answer.
@niutech I was having the similar issue which is caused by Rocket Loader Module by Cloudflare. Just disable it for the website and it will sort out all your related issues.
.queue()
and .dequeue()
Queues in jQuery are used for animations. You can use them for any purpose you like. They are an array of functions stored on a per element basis, using jQuery.data()
. They are First-In-First-Out (FIFO). You can add a function to the queue by calling .queue()
, and you remove (by calling) the functions using .dequeue()
.
To understand the internal jQuery queue functions, reading the source and looking at examples helps me out tremendously. One of the best examples of a queue function I've seen is .delay()
:
$.fn.delay = function( time, type ) {
time = jQuery.fx ? jQuery.fx.speeds[time] || time : time;
type = type || "fx";
return this.queue( type, function() {
var elem = this;
setTimeout(function() {
jQuery.dequeue( elem, type );
}, time );
});
};
fx
The default queue in jQuery is fx
. The default queue has some special properties that are not shared with other queues.
$(elem).queue(function(){});
the fx
queue will automatically dequeue
the next function and run it if the queue hasn't started. dequeue()
a function from the fx
queue, it will unshift()
(push into the first location of the array) the string "inprogress"
- which flags that the queue is currently being run.fx
queue is used by .animate()
and all functions that call it by default.NOTE: If you are using a custom queue, you must manually .dequeue()
the functions, they will not auto start!
You can retrieve a reference to a jQuery queue by calling .queue()
without a function argument. You can use the method if you want to see how many items are in the queue. You can use push
, pop
, unshift
, shift
to manipulate the queue in place. You can replace the entire queue by passing an array to the .queue()
function.
Quick Examples:
// lets assume $elem is a jQuery object that points to some element we are animating.
var queue = $elem.queue();
// remove the last function from the animation queue.
var lastFunc = queue.pop();
// insert it at the beginning:
queue.unshift(lastFunc);
// replace queue with the first three items in the queue
$elem.queue(queue.slice(0,3));

// lets do something with google maps:
var $map = $("#map_canvas");
var myLatlng = new google.maps.LatLng(-34.397, 150.644);

var geocoder = new google.maps.Geocoder();
var map = new google.maps.Map($map[0], myOptions);
var resized = function() {
// simple animation callback - let maps know we resized

I developed an $.ajaxQueue()
plugin that uses the $.Deferred
, .queue()
, and $.ajax()
to also pass back a promise that is resolved when the request completes. Another version of $.ajaxQueue
that still works in 1.4 is posted on my answer to Sequencing Ajax Requests
/*
* jQuery.ajaxQueue - A queue for ajax requests
*
* (c) 2011 Corey Frang
* Dual licensed under the MIT and GPL licenses.
*
* Requires jQuery 1.5+
*/
(function($) {
// jQuery on an empty object, we are going to use this as our Queue
var ajaxQueue = $({});
$.ajaxQueue = function( ajaxOpts ) {
var jqXHR,
dfd = $.Deferred(),
promise = dfd.promise();
// queue our ajax request
ajaxQueue.queue( doRequest );
// add the abort method
promise.abort = function( statusText ) {
// proxy abort to the jqXHR if it is active
if ( jqXHR ) {
return jqXHR.abort( statusText );
}
// if there wasn't already a jqXHR we need to remove from queue
var queue = ajaxQueue.queue(),
index = $.inArray( doRequest, queue );
if ( index > -1 ) {
queue.splice( index, 1 );
}
// and then reject the deferred
dfd.rejectWith( ajaxOpts.context || ajaxOpts,
[ promise, statusText, "" ] );
return promise;
};
// run the actual query
function doRequest( next ) {
jqXHR = $.ajax( ajaxOpts )
.done( dfd.resolve )
.fail( dfd.reject )
.then( next, next );
}
return promise;
};
})(jQuery);
I have now added this as an article on learn.jquery.com, there are other great articles on that site about queues, go look.
You can handle it using this :
catch((error) => {
this.setState({
typing_animation_button: false,
});
console.log(error);
if ('Timeout' || 'Network request failed') {
toast_show = true;
toast_type = 'error';
toast_text = 'Network failure';
}
this.setState({
disable_button: false,
});
});
Try this:
subset(studentdata, Drink=='water')
that should do it.
An important reason is to add one and only one variable as the "Root" of your namespace...
var MyNamespace = {}
MyNamespace.foo= function() {
}
or
var MyNamespace = {
foo: function() {
},
...
}
There are many techniques for namespacing. It's become more important with the plethora of JavaScript modules available.
simply code : use this code in onCreate()
getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN
);

I found an a bit different solution of my problem regarding this context. Thought worth sharing.
Most of the example create readStreams
from file. But in my case readStream
has to be created from JSON
string coming from a message pool.
var jsonStream = through2.obj(function(chunk, encoding, callback) {
this.push(JSON.stringify(chunk, null, 4) + '\n');
callback();
});
// message.value --> value/text to write in write.txt
jsonStream.write(JSON.parse(message.value));
var writeStream = sftp.createWriteStream("/path/to/write/write.txt");
//"close" event didn't work for me!
writeStream.on( 'close', function () {
console.log( "- done!" );
sftp.end();
}
);
//"finish" event didn't work for me either!
writeStream.on( 'close', function () {
console.log( "- done!"
sftp.end();
}
);
// finally this worked for me!
jsonStream.on('data', function(data) {
var toString = Object.prototype.toString.call(data);
console.log('type of data:', toString);
console.log( "- file transferred" );
});
jsonStream.pipe( writeStream );
You have an extra '{' before return type. You may also want to put '==' instead of '=' in if and else condition.
It is maybe worth mentioning ave
. ave
is tapply
's friendly cousin. It returns results in a form that you can plug straight back into your data frame.
dfr <- data.frame(a=1:20, f=rep(LETTERS[1:5], each=4))
means <- tapply(dfr$a, dfr$f, mean)
## A B C D E
## 2.5 6.5 10.5 14.5 18.5
## great, but putting it back in the data frame is another line:
dfr$m <- means[dfr$f]
dfr$m2 <- ave(dfr$a, dfr$f, FUN=mean) # NB argument name FUN is needed!
dfr
## a f m m2
## 1 A 2.5 2.5
## 2 A 2.5 2.5
## 3 A 2.5 2.5
## 4 A 2.5 2.5
## 5 B 6.5 6.5
## 6 B 6.5 6.5
## 7 B 6.5 6.5
## ...
There is nothing in the base package that works like ave
for whole data frames (as by
is like tapply
for data frames). But you can fudge it:
dfr$foo <- ave(1:nrow(dfr), dfr$f, FUN=function(x) {
x <- dfr[x,]
sum(x$m*x$m2)
})
dfr
## a f m m2 foo
## 1 1 A 2.5 2.5 25
## 2 2 A 2.5 2.5 25
## 3 3 A 2.5 2.5 25
## ...

You remove the original image here:
newImg.animate(css, SPEED, function() {
img.remove();
newImg.removeClass('morpher');
(callback || function() {})();
});
And all that's left behind is newImg
. Then you reset link references the image using #rocket
:
$("#rocket").attr('src', ...
But your newImg
doesn't have an id
attribute let alone an id
of rocket
.
To fix this, you need to remove img
and then set the id
attribute of newImg
to rocket
:
newImg.animate(css, SPEED, function() {
var old_id = img.attr('id');
img.remove();
newImg.attr('id', old_id);
newImg.removeClass('morpher');
(callback || function() {})();
});
And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/
UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:
$("#resetlink").click(function(){
clearInterval(timerRocket);
$("#wrapper").css('top', '250px');
$('.throbber, .morpher').remove(); // Clear out the new stuff.
$("#rocket").show(); // Bring the original back.
});
And in the newImg.load
function, grab the images original size:
var orig = {
width: img.width(),
height: img.height()
};
And finally, the callback for finishing the morphing animation becomes this:
newImg.animate(css, SPEED, function() {
img.css(orig).hide();
(callback || function() {})();
});
New and improved: http://jsfiddle.net/ambiguous/W2K9D/1/
The leaking of $('.throbber, .morpher')
outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.
This is similar to CommonsWare answer but with a minor tweak: android:gravity="top|start"
. Complete code example:
<EditText
android:id="@+id/EditText02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:lines="5"
android:gravity="top|start"
android:inputType="textMultiLine"
android:scrollHorizontally="false"

A solution that actually works:
public void Test() {
throw new MyCustomException("You can't do that!");
}
[TestMethod]
public void ThisWillPassIfExceptionThrown()
{
var exception = Assert.ThrowsException<MyCustomException>(
() => Test(),
"This should have thrown!");
Assert.AreEqual("You can't do that!", exception.Message);
}
This works with using Microsoft.VisualStudio.TestTools.UnitTesting;
.
You can also use Microsoft Visual Studio compiler instead of Cygwin or MinGW in Windows environment as the compiler for CLion.
Just go to find Actions in Help and type "Registry" without " and enable CLion.enable.msvc Now configure toolchain with Microsoft Visual Studio Compiler. (You need to download it if not already downloaded)
follow this link for more details: https://www.jetbrains.com/help/clion/quick-tutorial-on-configuring-clion-on-windows.html
For uploading, the S3 SDK has two putObject methods:
PutObjectRequest(String bucketName, String key, File file)
and
PutObjectRequest(String bucketName, String key, InputStream input, ObjectMetadata metadata)
The inputstream+ObjectMetadata method needs a minimum metadata of Content Length of your inputstream. If you don't, then it will buffer in-memory to get that information, this could cause OOM. Alternatively, you could do your own in-memory buffering to get the length, but then you need to get a second inputstream.
Not asked by the OP (limitations of his environment), but for someone else, such as me. I find it easier, and safer (if you have access to temp file), to write the inputstream to a temp file, and put the temp file. No in-memory buffer, and no requirement to create a second inputstream.
AmazonS3 s3Service = new AmazonS3Client(awsCredentials);
File scratchFile = File.createTempFile("prefix", "suffix");
try {
FileUtils.copyInputStreamToFile(inputStream, scratchFile);
PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, id, scratchFile);
PutObjectResult putObjectResult = s3Service.putObject(putObjectRequest);
} finally {
if(scratchFile.exists()) {
scratchFile.delete();
}
}
You just need to return
from the main function at some point. The error message says that the function is defined to return a value but you are not returning anything.
/* .... */
if (Date1 == Date2)
fprintf (stderr , "Indicating that the first date is equal to second date.\n");
return 0;
}
You can use segments
to add the bars in base graphics. Here epsilon
controls the line across the top and bottom of the line.
plot (x, y, ylim=c(0, 6))
epsilon = 0.02
for(i in 1:5) {
up = y[i] + sd[i]
low = y[i] - sd[i]
segments(x[i],low , x[i], up)
segments(x[i]-epsilon, up , x[i]+epsilon, up)
segments(x[i]-epsilon, low , x[i]+epsilon, low)
}
As @thelatemail points out, I should really have used vectorised function calls:
segments(x, y-sd,x, y+sd)
epsilon = 0.02
segments(x-epsilon,y-sd,x+epsilon,y-sd)
segments(x-epsilon,y+sd,x+epsilon,y+sd)

Yes, you use the AndroidManifest.xml
file. You can actually even have more than one launcher activity specified in your application manifest. To make an activity seen on the launcher you add these attributes to your activity in the manifest:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
What you are trying to do is an extension of string slicing in Python:
Say all strings are of length 10, last char to be removed:
>>> st[:9]
'abcdefghi'
To remove last N
characters:
>>> N = 3
>>> st[:-N]
'abcdefg'
Below is the code that Bootstrap uses. Colors are bit different but the concept is same. This is if you are using LESS to compile CSS:
// Form control focus state
//
// Generate a customized focus state and for any input with the specified color,
// which defaults to the `@input-focus-border` variable.
//
// We highly encourage you to not customize the default value, but instead use
// this to tweak colors on an as-needed basis. This aesthetic change is based on
// WebKit's default styles, but applicable to a wider range of browsers. Its
// usability and accessibility should be taken into account with any change.
//
// Example usage: change the default blue border and shadow to white for better
// contrast against a dark gray background.
.form-control-focus(@color: @input-border-focus) {
@color-rgba: rgba(red(@color), green(@color), blue(@color), .6);
&:focus {
border-color: @color;
outline: 0;
.box-shadow(~"inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px @{color-rgba}");
}
}
If you are not using LESS then here's the compiled version:
.form-control:focus {
border-color: #66afe9;
outline: 0;
-webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(102, 175, 233, 0.6);
box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(102, 175, 233, 0.6);
}
Both of these two top-rated answers are wrong. Check out the MDN description on the concurrency model and the event loop, and it should become clear what's going on (that MDN resource is a real gem). And simply using setTimeout
can be adding unexpected problems in your code in addition to "solving" this little problem.
What's actually going on here is not that "the browser might not be quite ready yet because concurrency," or something based on "each line is an event that gets added to the back of the queue".
The jsfiddle provided by DVK indeed illustrates a problem, but his explanation for it isn't correct.
What's happening in his code is that he's first attaching an event handler to the click
event on the #do
button.
Then, when you actually click the button, a message
is created referencing the event handler function, which gets added to the message queue
. When the event loop
reaches this message, it creates a frame
on the stack, with the function call to the click event handler in the jsfiddle.
And this is where it gets interesting. We're so used to thinking of Javascript as being asynchronous that we're prone to overlook this tiny fact: Any frame has to be executed, in full, before the next frame can be executed. No concurrency, people.
What does this mean? It means that whenever a function is invoked from the message queue, it blocks the queue until the stack it generates has been emptied. Or, in more general terms, it blocks until the function has returned. And it blocks everything, including DOM rendering operations, scrolling, and whatnot. If you want confirmation, just try to increase the duration of the long running operation in the fiddle (e.g. run the outer loop 10 more times), and you'll notice that while it runs, you cannot scroll the page. If it runs long enough, your browser will ask you if you want to kill the process, because it's making the page unresponsive. The frame is being executed, and the event loop and message queue are stuck until it finishes.
So why this side-effect of the text not updating? Because while you have changed the value of the element in the DOM — you can console.log()
its value immediately after changing it and see that it has been changed (which shows why DVK's explanation isn't correct) — the browser is waiting for the stack to deplete (the on
handler function to return) and thus the message to finish, so that it can eventually get around to executing the message that has been added by the runtime as a reaction to our mutation operation, and in order to reflect that mutation in the UI.
This is because we are actually waiting for code to finish running. We haven't said "someone fetch this and then call this function with the results, thanks, and now I'm done so imma return, do whatever now," like we usually do with our event-based asynchronous Javascript. We enter a click event handler function, we update a DOM element, we call another function, the other function works for a long time and then returns, we then update the same DOM element, and then we return from the initial function, effectively emptying the stack. And then the browser can get to the next message in the queue, which might very well be a message generated by us by triggering some internal "on-DOM-mutation" type event.
The browser UI cannot (or chooses not to) update the UI until the currently executing frame has completed (the function has returned). Personally, I think this is rather by design than restriction.
Why does the setTimeout
thing work then? It does so, because it effectively removes the call to the long-running function from its own frame, scheduling it to be executed later in the window
context, so that it itself can return immediately and allow the message queue to process other messages. And the idea is that the UI "on update" message that has been triggered by us in Javascript when changing the text in the DOM is now ahead of the message queued for the long-running function, so that the UI update happens before we block for a long time.
Note that a) The long-running function still blocks everything when it runs, and b) you're not guaranteed that the UI update is actually ahead of it in the message queue. On my June 2018 Chrome browser, a value of 0
does not "fix" the problem the fiddle demonstrates — 10 does. I'm actually a bit stifled by this, because it seems logical to me that the UI update message should be queued up before it, since its trigger is executed before scheduling the long-running function to be run "later". But perhaps there're some optimisations in the V8 engine that may interfere, or maybe my understanding is just lacking.
Okay, so what's the problem with using setTimeout
, and what's a better solution for this particular case?
First off, the problem with using setTimeout
on any event handler like this, to try to alleviate another problem, is prone to mess with other code. Here's a real-life example from my work:
A colleague, in a mis-informed understanding on the event loop, tried to "thread" Javascript by having some template rendering code use setTimeout 0
for its rendering. He's no longer here to ask, but I can presume that perhaps he inserted timers to gauge the rendering speed (which would be the return immediacy of functions) and found that using this approach would make for blisteringly fast responses from that function.
First problem is obvious; you cannot thread javascript, so you win nothing here while you add obfuscation. Secondly, you have now effectively detached the rendering of a template from the stack of possible event listeners that might expect that very template to have been rendered, while it may very well not have been. The actual behaviour of that function was now non-deterministic, as was — unknowingly so — any function that would run it, or depend on it. You can make educated guesses, but you cannot properly code for its behaviour.
The "fix" when writing a new event handler that depended on its logic was to also use setTimeout 0
. But, that's not a fix, it is hard to understand, and it is no fun to debug errors that are caused by code like this. Sometimes there's no problem ever, other times it concistently fails, and then again, sometimes it works and breaks sporadically, depending on the current performance of the platform and whatever else happens to going on at the time. This is why I personally would advise against using this hack (it is a hack, and we should all know that it is), unless you really know what you're doing and what the consequences are.
But what can we do instead? Well, as the referenced MDN article suggests, either split the work into multiple messages (if you can) so that other messages that are queued up may be interleaved with your work and executed while it runs, or use a web worker, which can run in tandem with your page and return results when done with its calculations.
Oh, and if you're thinking, "Well, couldn't I just put a callback in the long-running function to make it asynchronous?," then no. The callback doesn't make it asynchronous, it'll still have to run the long-running code before explicitly calling your callback.
Update for 2021:
A lot has changed in 8ish years. Gradle continues to be a great tool. Now there's a whole section in the docs dedicated to configuring Integration Tests. I recommend you read the docs now.
Original Answer:
This took me a while to figure out and the online resources weren't great. So I wanted to document my solution.
This is a simple gradle build script that has an intTest source set in addition to the main and test source sets:
apply plugin: "java"
sourceSets {
// Note that just declaring this sourceset creates two configurations.
intTest {
java {
compileClasspath += main.output
runtimeClasspath += main.output
}
}
}
configurations {
intTestCompile.extendsFrom testCompile
intTestRuntime.extendsFrom testRuntime
}
task intTest(type:Test){
description = "Run integration tests (located in src/intTest/...)."
testClassesDir = project.sourceSets.intTest.output.classesDir
classpath = project.sourceSets.intTest.runtimeClasspath

This my dynamical programming implementation in JS. It will return an array of arrays, each holding the subsequences summing to the provided target value.
function getSummingItems(a,t){_x000D_
return a.reduce((h,n) => Object.keys(h)_x000D_
.reduceRight((m,k) => +k+n <= t ? (m[+k+n] = m[+k+n] ? m[+k+n].concat(m[k].map(sa => sa.concat(n)))_x000D_
: m[k].map(sa => sa.concat(n)),m)_x000D_
: m, h), {0:[[]]})[t];_x000D_
}_x000D_
var arr = Array(20).fill().map((_,i) => i+1), // [1,2,..,20]_x000D_
tgt = 42,_x000D_
res = [];_x000D_
_x000D_
console.time("test");_x000D_
res = getSummingItems(arr,tgt);_x000D_

Just search for the character at index 0 and compare it against the value you're looking for!
use SimpleDateFormat

Made it work successfully using the 2 methods: Stephan202's encapsulation and multiple event listeners. I have 3 search tabs, let's define their input text id's in an Array:
var ids = new Array("searchtab1", "searchtab2", "searchtab3");
When the content of searchtab1 changes, I want to update searchtab2 and searchtab3. Did it this way for encapsulation:
for (var i in ids) {
$("#" + ids[i]).change(function() {
for (var j in ids) {
if (this != ids[j]) {
$("#" + ids[j]).val($(this).val());
}
}
});
}
Multiple event listeners:
for (var i in ids) {
for (var j in ids) {
if (ids[i] != ids[j]) {
$("#" + ids[i]).change(function() {
$("#" + ids[j]).val($(this).val());
});
}
}
}
I like both methods, but the programmer chose encapsulation, however multiple event listeners worked also. We used Chrome to test it.
Note that if you use Android Studio and download through its SDK Manager, the SDK is downloaded to ~/Library/Android/sdk
by default, not ~/.android-sdk-macosx
.
I would rather add this as a comment to @brismuth's excellent answer, but it seems I don't have enough reputation points yet.
In case someone is trying to run a script in a RAILS environment, rails provide a runner to execute scripts in rails context via
rails runner my_script.rb

In another way to limit a string in php and add on readmore text or like '...' using below code
if (strlen(preg_replace('#^https?://#', '', $string)) > 30) {
echo substr(preg_replace('#^https?://#', '', $string), 0, 35).'…';
}
In modern browsers, you can simply use css:
th {
position: sticky;
top: 0;
z-index: 2;
}
If anyone wants to generate PDFs on Android device, here is how to do it:
Use String.Replace()
if you just want to replace the dots from string. Alternative would be to use Pattern-Matcher
with StringBuilder
, this gives you more flexibility as you can find groups that are between dots. If using the latter, i would recommend that you ignore empty entries with "\\.+"
.
public static int count(String str, String regex) {
int i = 0;
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(str);
while (m.find()) {
m.group();
i++;
}
return i;
}
public static void main(String[] args) {
int i = 0, j = 0, k = 0;
String str = "-.-..-...-.-.--..-k....k...k..k.k-.-";
// this will just remove dots
System.out.println(str.replaceAll("\\.", ""));
// this will just remove sequences of ".." dots
System.out.println(str.replaceAll("\\.{2}", ""));
// this will just remove sequences of dots, and gets
// multiple of dots as 1
System.out.println(str.replaceAll("\\.+", ""));
/* for this to be more obvious, consider following */
System.out.println(count(str, "\\."));
System.out.println(count(str, "\\.{2}"));
System.out.println(count(str, "\\.+"));
}
The output will be:
--------kkkkk--
-.--.-.-.---kk.kk.k-.-

If you are able to see the project in Eclipse project explorer but unable to see the project while adding the project to the web server, follow project properties -> Project Facets, make sure Dynamic Web Module & Java were ticked.
Sometimes it can be at: C:\Users\user-name\AppData\Local\Programs\Git\cmd

If you are planning to hide show some span based on click event which is initially hidden with style="display:none" then .toggle() is best option to go with.
$("span").toggle();
Reasons : Each time you don't need to check whether the style is already there or not. .toggle() will take care of that automatically and hide/show span based on current state.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="button" value="Toggle" onclick="$('#hiddenSpan').toggle();"/>_x000D_
<br/>_x000D_
<br/>_x000D_
<span id="hiddenSpan" style="display:none">Just toggle me</span>

If you have carriage return/line feeds within columns, str_getcsv will not work.
Try https://github.com/synappnz/php-csv
Use:
include "csv.php";
$csv = new csv(file_get_contents("filename.csv"));
$rows = $csv->rows();
foreach ($rows as $row)
{
// do something with $row
}
To get information about the current store from anywhere in Magento, use:
<?php
$store = Mage::app()->getStore();
This will give you a Mage_Core_Model_Store object, which has some of the information you need:
<?php
$name = $store->getName();
As for your other question about line number, I'm not sure what you mean. If you mean that you want to know what line number in the code you are on (for error handling, for instance), try:
<?php
$line = __LINE__;
$file = __FILE__;
$class = __CLASS__;
$method = __METHOD__;
$namespace = __NAMESPACE__;
class PushObjects {
testMethod(): Array<number> {
//declaration and initialisation of array onject
var objs: number[] = [1,2,3,4,5,7];
//push the elements into the array object
objs.push(100);
//pop the elements from the array
objs.pop();
return objs;
}
}
let pushObj = new PushObjects();
//create the button element from the dom object
let btn = document.createElement('button');
//set the text value of the button
btn.textContent = "Click here";
//button click event
btn.onclick = function () {
alert(pushObj.testMethod());
}
document.body.appendChild(btn);
In theory, the most efficient way will depend on which implementation of Map. The official way to do this is to call map.entrySet()
, which returns a set of Map.Entry
, each of which contains a key and a value (entry.getKey()
and entry.getValue()
).
In an idiosyncratic implementation, it might make some difference whether you use map.keySet()
, map.entrySet()
or something else. But I can't think of a reason why anyone would write it like that. Most likely it makes no difference to performance what you do.
And yes, the order will depend on the implementation - as well as (possibly) the order of insertion and other hard-to-control factors.
[edit] I wrote valueSet()
originally but of course entrySet()
is actually the answer.
It require to include Content-Type:application/json
in web api request header section when not mention any content then by default it is Content-Type:text/plain
passes to request.
Best way to test api on postman tool.
you have to name your checkboxes accordingly:
<input type="checkbox" name="check_list[]" value="…" />
you can then access all checked checkboxes with
// loop over checked checkboxes
foreach($_POST['check_list'] as $checkbox) {
// do something
}
ps. make sure to properly escape your output (htmlspecialchars()
)
If you decide to use Underscore.js you better do
var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' };
var keys = [];
_.each( foo, function( val, key ) {
keys.push(key);
});
console.log(keys);
Here's what I did in Android Studio Beta (0.8.14)
And vola, my package name has now changed and builds successfully.
Variables in single-quotes are not evaluated. Use double quotes:
ssh [email protected] "~/tools/run_pvt.pl $BUILD_NUMBER"
The shell will expand variables in double-quotes, but not in single-quotes. This will change into your desired string before being passed to the ssh
command.
I answered a virtually identical question just the other day: Save CSV files into mysql database
MySQL has a feature LOAD DATA INFILE
, which allows it to import a CSV file directly in a single SQL query, without needing it to be processed in a loop via your PHP program at all.
Simple example:
<?php
$query = <<<eof
LOAD DATA INFILE '$fileName'
INTO TABLE tableName
FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
(field1,field2,field3,etc)
eof;
$db->query($query);
?>
It's as simple as that.
No loops, no fuss. And much much quicker than parsing it in PHP.

In my case I was facing the problem because in my tomcat process specific keystore was given using
-Djavax.net.ssl.trustStore=/pathtosomeselfsignedstore/truststore.jks
Wheras I was importing the certificate to the cacert of JRE/lib/security and the changes were not reflecting. Then I did below command where /tmp/cert1.test contains the certificate of the target server
keytool -import -trustcacerts -keystore /pathtosomeselfsignedstore/truststore.jks -storepass password123 -noprompt -alias rapidssl-myserver -file /tmp/cert1.test
We can double check if the certificate import is successful
keytool -list -v -keystore /pathtosomeselfsignedstore/truststore.jks
and see if your taget server is found against alias rapidssl-myserver
Put in config.php this

Here's a way to do it in Python without NumPy. Create a function that returns what you want and use a list comprehension, or the map function.
>>> a = [1, 2, 3, -4, 5]
>>> def zero_if_negative(x):
... if x < 0:
... return 0
... return x
...
>>> [zero_if_negative(x) for x in a]
[1, 2, 3, 0, 5]
>>> map(zero_if_negative, a)
[1, 2, 3, 0, 5]
This worked much better in my case.
HTML in PHP: <a href=".$link_address.">Link</a>
you can use commons csv to convert into CSV format. or use POI to convert into xls. if you need helper to convert into xls, you can use jxls, it can convert java bean (or list) into excel with expression language.
Basically, the json doc maybe is a json array, right? so it will be same. the result will be list, and you just write the property that you want to display in excel format that will be read by jxls. See http://jxls.sourceforge.net/reference/collections.html
If the problem is the json can't be read in the jxls excel property, just serialize it into collection of java bean first.
As Angular moved on with the release, I faced this same issue. As per version 2.1.0 the Route
interface looks like:
export interface Route {
path?: string;
pathMatch?: string;
component?: Type<any>;
redirectTo?: string;
outlet?: string;
canActivate?: any[];
canActivateChild?: any[];
canDeactivate?: any[];
canLoad?: any[];
data?: Data;
resolve?: ResolveData;
children?: Route[];
loadChildren?: LoadChildren;
}
So my solutions was the following:
const routes: Routes = [
{ path: '', component: HomeComponent },
{ path: '404', component: NotFoundComponent },
{ path: '**', redirectTo: '404' }
];
You can upload up to 8 screenshots. Those screenshots must be one of the dimensions (sizes) you listed; you can have multiple screenshots of the same dimensions.
I know this is an old thread but I thought this might help someone:
Mobile devices have greater height than width, in contrary, computers have greater width than height. For example:
@media all and (max-width: 320px) and (min-height: 320px)
so that would have to be done for every width i guess.
JavaScript With Selenium WebDriver
Selenium is one of the most popular automated testing suites. Selenium is designed in a way to support and encourage automation testing of functional aspects of web based applications and a wide range of browsers and platforms.
public static WebDriver driver;
public static void main(String[] args) {
driver = new FirefoxDriver(); // This opens a window
String url = "----";
/*driver.findElement(By.id("username")).sendKeys("yashwanth.m");
driver.findElement(By.name("j_password")).sendKeys("yashwanth@123");*/
JavascriptExecutor jse = (JavascriptExecutor) driver;
if (jse instanceof WebDriver) {
//Launching the browser application
jse.executeScript("window.location = \'"+url+"\'");
jse.executeScript("document.getElementById('username').value = \"yash\";");
// Tag having name then
driver.findElement(By.xpath(".//input[@name='j_password']")).sendKeys("admin");
//Opend Site and click on some links. then you can apply go(-1)--> back forword(-1)--> front.
//Refresheing the web-site. driver.navigate().refresh();
jse.executeScript("window.history.go(0)");
jse.executeScript("window.history.go(-2)");
jse.executeScript("window.history.forward(-2)");
String title = (String)jse.executeScript("return document.title");
System.out.println(" Title Of site : "+title);
String domain = (String)jse.executeScript("return document.domain");
System.out.println("Web Site Domain-Name : "+domain);
// To get all NodeList[1052] document.querySelectorAll('*'); or document.all
jse.executeAsyncScript("document.getElementsByTagName('*')");
String error=(String) jse.executeScript("return window.jsErrors");
System.out.println("Windowerrors : "+error);
System.out.println("To Find the input tag position from top");
ArrayList<?> al = (ArrayList<?>) jse.executeScript(
"var source = [];"+
"var inputs = document.getElementsByTagName('input');"+
"for(var i = 0; i < inputs.length; i++) { " +
" source[i] = inputs[i].offsetParent.offsetTop" + //" inputs[i].type = 'radio';"
"}"+
"return source"
);//inputs[i].offsetParent.offsetTop inputs[i].type
System.out.println("next");
System.out.println("array : "+al);
// (CTRL + a) to access keyboard keys. org.openqa.selenium.Keys
Keys k = null;
String selectAll = Keys.chord(Keys.CONTROL, "a");
WebElement body = driver.findElement(By.tagName("body"));
body.sendKeys(selectAll);
// Search for text in Site. Gets all ViewSource content and checks their.
if (driver.getPageSource().contains("login")) {
System.out.println("Text present in Web Site");
}
Long clent_height = (Long) jse.executeScript("return document.body.clientHeight");
System.out.println("Client Body Height : "+clent_height);
// using selenium we con only execute script but not JS-functions.
}
driver.quit(); // to close browser

To Execute User-Functions, Writing JS in to a file and reading as String and executing it to easily use.
Scanner sc = new Scanner(new FileInputStream(new File("JsFile.txt")));
String js_TxtFile = "";
while (sc.hasNext()) {
String[] s = sc.next().split("\r\n");
for (int i = 0; i < s.length; i++) {
js_TxtFile += s[i];
js_TxtFile += " ";
}
}
String title = (String) jse.executeScript(js_TxtFile);
System.out.println("Title : "+title);
document.title & document.getElementById() is a property/method available in Browsers.

var title = getTitle();
return title;
function getTitle() {
return document.title;

Always use either String.valueOf(number)
or Integer.toString(number)
.
Using "" + number is an overhead and does the following:
StringBuilder sb = new StringBuilder();
sb.append("");
sb.append(number);
return sb.toString();
For everyone using editors like Komodo Edit (win10) add sys.stdout.flush()
to:
def mp_worker((inputs, the_time)):
print " Process %s\tWaiting %s seconds" % (inputs, the_time)
time.sleep(int(the_time))
print " Process %s\tDONE" % inputs
sys.stdout.flush()
or as first line to:
if __name__ == '__main__':
sys.stdout.flush()
This helps to see what goes on during the run of the script; in stead of having to look at the black command line box.
I would think you'll want to think about if things really belong in a session state. This is something I find myself doing every now and then and it's a nice strongly typed approach to the whole thing but you should be careful when putting things in the session context. Not everything should be there just because it belongs to some user.
in global.asax hook the OnSessionStart event
void OnSessionStart(...)
{
HttpContext.Current.Session.Add("__MySessionObject", new MySessionObject());
}
From anywhere in code where the HttpContext.Current property != null you can retrive that object. I do this with an extension method.
public static MySessionObject GetMySessionObject(this HttpContext current)
{
return current != null ? (MySessionObject)current.Session["__MySessionObject"] : null;
}
This way you can in code
void OnLoad(...)
{
var sessionObj = HttpContext.Current.GetMySessionObject();
// do something with 'sessionObj'
}
Here is the Working example: Get javascript variable value on the same page in php.
<script>
var p1 = "success";
</script>
<?php
echo "<script>document.writeln(p1);</script>";
?>
You can catch it like any other exception:
try {
foo();
}
catch (const std::bad_alloc&) {
return -1;
}
Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.
In general you cannot, and should not try, to respond to this error. bad_alloc
indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.
Worse, modern operating systems often over-allocate: on such systems, malloc
and new
can return a valid pointer even if there is not enough free memory left – std::bad_alloc
will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).
The only thing you could do when catching std::bad_alloc
is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).
In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:
It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.1
OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:
lru_cache<widget> widget_cache;
double perform_operation(int widget_id) {
std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
if (not maybe_widget) {
maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
}
return maybe_widget->frobnicate();
}
…
for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
try {
return perform_operation(widget_id);
} catch (std::bad_alloc const&) {
if (widget_cache.empty()) throw; // memory error elsewhere.
widget_cache.remove_oldest();
}
}
// Handle too many failed attempts here.
But even here, using std::set_new_handler
instead of handling std::bad_alloc
provides the same benefit and would be much simpler.
1 If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.
new
in c++?The usual notion is that if new
operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc
.
However, something more happens even before a bad_alloc
exception is thrown:
C++03 Section 3.7.4.1.3: says
An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.
Consider the following code sample:
#include <iostream>
#include <cstdlib>
// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
std::cerr << "Unable to satisfy request for memory\n";
std::abort();
}
int main()
{
//set the new_handler
std::set_new_handler(outOfMemHandler);
//Request huge memory size, that will cause ::operator new to fail
int *pBigDataArray = new int[100000000L];
return 0;
}
In the above example, operator new
(most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler()
will be called, and the program will abort after issuing an error message.
As seen here the default behavior of new
operator when unable to fulfill a memory request, is to call the new-handler
function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort()
, outOfMemHandler()
would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.
new_handler
and set_new_handler
?new_handler
is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler
is a function that takes and returns a new_handler
.
Something like:
typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();
set_new_handler's parameter is a pointer to the function operator new
should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.
Given the behavior of new
a well designed user program should handle out of memory conditions by providing a proper new_handler
which does one of the following:
Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.
Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler
). The next time operator new calls the new-handler function, it will get the one most recently installed.
(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)
Uninstall the new-handler: This is done by passing a null pointer to set_new_handler
. With no new-handler installed, operator new
will throw an exception ((convertible to) std::bad_alloc
) when memory allocation is unsuccessful.
Throw an exception convertible to std::bad_alloc
. Such exceptions are not be caught by operator new
, but will propagate to the site originating the request for memory.
Not return: By calling abort
or exit
.

1) Download the JDBC Driver here.
2) unzip the file and go to sqljdbc_version\fra\auth\x86 or \x64
3) copy the sqljdbc_auth.dll to C:\Program Files\Java\jre_Version\bin
4) Finally restart eclipse
Installing framework 4.0 redistributable is also enough to create application pool. You can download it from here.
Don't mess with the library path! Eclipse builds it itself!
Instead, go into the library settings for your projects and, for each jar/etc that requires a native library, expand it in the Libraries tab. In the tree view there, each library has items for source/javadoc and native library locations.
Specifically: select Project
, right click -> Properties / Java Build Path / Libraries tab, select a .jar, expand it, select Native library location, click Edit, folder chooser dialog will appear)
Messing with the library path on the command line should be your last ditch effort, because you might break something that is already properly set by eclipse.
select * from your_table where your_field like '%a%b%'
and be prepared to wait a while...
Edit: note that this pattern looks for an 'a' followed by a 'b' (possibly with other "stuff" in between) -- rereading your question, that may not be what you wanted...

This is a known Excel bug...
The best and fastest workaround is the Columns.AutoFit

Temp = ActiveCell.ColumnWidth
ActiveCell.Columns.AutoFit
ActiveCell.ColumnWidth = Temp
Application.ScreenUpdating = True
End Sub
if not exist "%USERPROFILE%\.qgis-custom\" (
mkdir "%USERPROFILE%\.qgis-custom" 2>nul
if not errorlevel 1 (
xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)
)
You have it almost done. The logic is correct, just some little changes.
This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).
If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.
If everyting is ok, files are copied.
All paths are quoted to avoid problems with spaces.
It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files
mkdir "%USERPROFILE%\.qgis-custom" 2>nul
if not errorlevel 1 (
xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)
In both code samples, files are not copied if the folder is not being created during the script execution.
EDITED - As dbenham comments, the same code can be written as a single line
md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
The code after the &&
will only be executed if the previous command does not set errorlevel. If mkdir
fails, xcopy
is not executed.
I got it to work by doing this, assuming you are using PDO.
//Place query here, let's say you want all the users that have blue as their favorite color
$sql = "SELECT name FROM user WHERE favorite_color = :color";
//set parameters
//you may set as many parameters as you have on your query
$params['color'] = blue;
//create the prepared statement, by getting the doctrine connection
$stmt = $this->entityManager->getConnection()->prepare($sql);
$stmt->execute($params);
//I used FETCH_COLUMN because I only needed one Column.
return $stmt->fetchAll(PDO::FETCH_COLUMN);
You can change the FETCH_TYPE to suit your needs.
Not sure if anyone else will find this helpful, but I encountered the same error and searched all over for any anonymous users...and there weren't any. The problem ended up being that the user account was set to "Require SSL" - which I found in PHPMyAdmin by going to User Accounts and clicking on Edit Privileges for the user. As soon as I unchecked this option, everything worked as expected!
I have included an example here which demonstrates how you might store the mask in a database column as an int, and how you would reinstate the mask later on:
public enum DaysBitMask { Mon=0, Tues=1, Wed=2, Thu = 4, Fri = 8, Sat = 16, Sun = 32 }
DaysBitMask mask = DaysBitMask.Sat | DaysBitMask.Thu;
bool test;
if ((mask & DaysBitMask.Sat) == DaysBitMask.Sat)
test = true;
if ((mask & DaysBitMask.Thu) == DaysBitMask.Thu)
test = true;
if ((mask & DaysBitMask.Wed) != DaysBitMask.Wed)
test = true;
// Store the value
int storedVal = (int)mask;
// Reinstate the mask and re-test
DaysBitMask reHydratedMask = (DaysBitMask)storedVal;
if ((reHydratedMask & DaysBitMask.Sat) == DaysBitMask.Sat)
test = true;
if ((reHydratedMask & DaysBitMask.Thu) == DaysBitMask.Thu)
test = true;
if ((reHydratedMask & DaysBitMask.Wed) != DaysBitMask.Wed)
test = true;
The easiest way to do this in my experience is with the Cloudmersive free native PHP library, just call convertDocumentDocxToPdf:
<?php
require_once(__DIR__ . '/vendor/autoload.php');
// Configure API key authorization: Apikey
$config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('Apikey', 'YOUR_API_KEY');
$apiInstance = new Swagger\Client\Api\ConvertDocumentApi(
new GuzzleHttp\Client(),
$config
);
$input_file = "/path/to/file.txt"; // \SplFileObject | Input file to perform the operation on.
try {
$result = $apiInstance->convertDocumentDocxToPdf($input_file);
print_r($result);
} catch (Exception $e) {
echo 'Exception when calling ConvertDocumentApi->convertDocumentDocxToPdf: ', $e->getMessage(), PHP_EOL;
}
?>
Be sure to replace $input_file with the appropriate file path. You can also configure it to use a byte array if you prefer to do it that way. The result will be the bytes of the converted PDF file.
There is no runtime impact, as compiler automatically replaces the * with concrete class names. If you decompile the .class file, you would never see import ...*
.
C# always uses * (implicitly) as you can only using
package name. You can never specify the class name at all. Java introduces the feature after c#. (Java is so tricky in many aspects but it's beyond this topic).
In Intellij Idea when you do "organize imports", it automatically replaces multiple imports of the same package with *. This is a mandantory feature as you can not turn it off (though you can increase the threshold).
The case listed by the accepted reply is not valid. Without * you still got the same issue. You need specify the pakcage name in your code no matter you use * or not.
where 1=0, This is done to check if the table exists. Don't know why 1=1 is used.
It's not a direct answer to the question but you could just use the OR-operator
( grep "#SystemMaxUse=" journald.conf > /dev/null && sed -i 's/\#SystemMaxUse=/SystemMaxUse=50M/g' journald.conf ) || echo "This file has been edited. You'll need to do it manually."
Here is what I did and it worked, created a session in PHP and used xmlhhtprequest to check if session is set whenever an HTML page loads and it worked for Cordova.
To complete J.F. Sebastian's answer, if you have a list of lists with different lengths, check out this great post from ActiveState. In short:
The built-in function zip does a similar job, but truncates the result to the length of the shortest list, so some elements from the original data may be lost afterwards.
To handle list of lists with different lengths, use:
def transposed(lists):
if not lists: return []
return map(lambda *row: list(row), *lists)
def transposed2(lists, defval=0):
if not lists: return []
return map(lambda *row: [elem or defval for elem in row], *lists)
Thanks to kind and patient help from golang-nuts, recipe is the following:
1) One needs to compile Go compiler for different target platforms and architectures. This is done from src folder in go installation. In my case Go installation is located in /usr/local/go
thus to compile a compiler you need to issue make
utility. Before doing this you need to know some caveats.
There is an issue about CGO library when cross compiling so it is needed to disable CGO library.
Compiling is done by changing location to source dir, since compiling has to be done in that folder
cd /usr/local/go/src
then compile the Go compiler:
sudo GOOS=windows GOARCH=386 CGO_ENABLED=0 ./make.bash --no-clean
You need to repeat this step for each OS and Architecture you wish to cross compile by changing the GOOS and GOARCH parameters.
If you are working in user mode as I do, sudo is needed because Go compiler is in the system dir. Otherwise you need to be logged in as super user. On Mac you may need to enable/configure SU access (it is not available by default), but if you have managed to install Go you possibly already have root access.
2) Once you have all cross compilers built, you can happily cross compile your application by using the following settings for example:
GOOS=windows GOARCH=386 go build -o appname.exe appname.go
GOOS=linux GOARCH=386 CGO_ENABLED=0 go build -o appname.linux appname.go
Change the GOOS and GOARCH to targets you wish to build.
If you encounter problems with CGO include CGO_ENABLED=0 in the command line. Also note that binaries for linux and mac have no extension so you may add extension for the sake of having different files. -o switch instructs Go to make output file similar to old compilers for c/c++ thus above used appname.linux can be any other extension.
p = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True)
p.kill()
p.kill()
ends up killing the shell process and cmd
is still running.
I found a convenient fix this by:
p = subprocess.Popen("exec " + cmd, stdout=subprocess.PIPE, shell=True)
This will cause cmd to inherit the shell process, instead of having the shell launch a child process, which does not get killed. p.pid
will be the id of your cmd process then.
p.kill()
should work.
I don't know what effect this will have on your pipe though.
When you're using GROUP BY
, you need to also use aggregate functions for the columns not inside your group by clause.
I don't know exactly what you're trying to do, but I guess this would work:
select
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000),
PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound,
MAX(qvalues.rid)
from
batchinfo join qvalues on batchinfo.rowid=qvalues.rowid
where
LEN(datapath)>4
group by
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000),
PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound
having
rid!=MAX(rid)
Edit:
What I'm trying to do here is a group by
with all fields but rid
. If that's not what you want, what you need to do in order to have a valid SQL statement is adding an aggregate function call for each removed group by field...
You can get this error in the context of, e.g. a Travis build that, by default, checks code out with git clone --depth=50 --branch=master
. To the best of my knowledge, you can control --depth
via .travis.yml
but not the --branch
. Since that results in only a single branch being tracked by the remote, you need to independently update the remote to track the desired remote's refs.
Before:
$ git branch -a
* master
remotes/origin/HEAD -> origin/master
remotes/origin/master
The fix:
$ git remote set-branches --add origin branch-1
$ git remote set-branches --add origin branch-2
$ git fetch
After:
$ git branch -a
* master
remotes/origin/HEAD -> origin/master
remotes/origin/branch-1
remotes/origin/branch-2
remotes/origin/master

x.transpose[6][3..8]

Removing an integer value
var a = [1, 2, 3]
a.remove(2)
a // Output => [1, 3]
Removing a string value
var a = ['a', 'ab', 'abc']
a.remove('abc')

It is also possible to remove an object inside the array via this Array.prototype.remove

Removing an object value
var a = [{a: 1, b: 2}, {a: 2, b: 2}, {a: 3, b: 2}]
a.remove({a: 1})

I am trying to do something similar to this. As commented above, I think you would want to build a new image with a custom Dockerfile (using the image you pulled as a base image), ADD
your certificate, then RUN update-ca-certificates
. This way you will have a consistent state each time you start a container from this new image.
# Dockerfile
FROM some-base-image:0.1
ADD you_certificate.crt:/container/cert/path
RUN update-ca-certificates
Let's say a docker build
against that Dockerfile produced IMAGE_ID. On the next docker run -d [any other options] IMAGE_ID
, the container started by that command will have your certificate info. Simple and reproducible.
Colin Pickard is mostly correct, but don't confuse the "password to open" protection for the entire file with the VBA password protection, which is completely different from the former and is the same for Office 2003 and 2007 (for Office 2007, rename the file to .zip and look for the vbaProject.bin inside the zip). And that technically the correct way to edit the file is to use a OLE compound document viewer like CFX to open up the correct stream. Of course, if you are just replacing bytes, the plain old binary editor may work.
BTW, if you are wondering about the exact format of these fields, they have it documented now:

A work-around for people who are experiencing a bug like Nathan:
The on-the-fly compiler seems to have a problem with this Extension Method error... adding static
didn't help me either.
I'd like to know what causes the bug?
But the work-around is to write a new Extension class (not nested) even in same file and re-build.
Figured that this thread is getting enough views that it's worth passing on (the limited) solution I found. Most people probably tried adding 'static' before google-ing for a solution! and I didn't see this work-around fix anywhere else.
Could you please try this ?
Create another item in post such as post.link then assign the link to it before send post to the render function.
post.link = '/posts/+ id.toString();
So, the above render function should be following instead.

For those looking to center the column elements on the screen when you don't have the exact number to fill your grid, I have written a little piece of JavaScript to return the class names:
function colCalculator(totalNumberOfElements, elementsPerRow, screenSize) {
var arrayFill = function (size, content) {
return Array.apply(null, Array(size)).map(String.prototype.valueOf, content);
};
var elementSize = parseInt(12 / elementsPerRow, 10);
var normalClassName = 'col-' + screenSize + '-' + elementSize;
var numberOfFittingElements = parseInt(totalNumberOfElements / elementsPerRow, 10) * elementsPerRow;
var numberOfRemainingElements = totalNumberOfElements - numberOfFittingElements;
var ret = arrayFill(numberOfFittingElements, normalClassName);
var remainingSize = 12 - numberOfRemainingElements * elementSize;
var remainingLeftSize = parseInt(remainingSize / 2, 10);
return ret.concat(arrayFill(numberOfRemainingElements, normalClassName + ' col-' + screenSize + '-push-' + remainingLeftSize));
}
If you have 5 elements and you want to have 3 per row on a md
screen, you do this:
colCalculator(5, 3, 'md')
>> ["col-md-4", "col-md-4", "col-md-4", "col-md-4 col-md-push-2", "col-md-4 col-md-push-2"]
Keep in mind, the second argument must be dividable by 12.

Handling categorical features scikit-learn expects all features to be numeric. So how do we include a categorical feature in our model?
Ordered categories: transform them to sensible numeric values (example: small=1, medium=2, large=3) Unordered categories: use dummy encoding (0/1) What are the categorical features in our dataset?
Ordered categories: weather (already encoded with sensible numeric values) Unordered categories: season (needs dummy encoding), holiday (already dummy encoded), workingday (already dummy encoded) For season, we can't simply leave the encoding as 1 = spring, 2 = summer, 3 = fall, and 4 = winter, because that would imply an ordered relationship. Instead, we create multiple dummy variables:
# An utility function to create dummy variable
`def create_dummies( df, colname ):
col_dummies = pd.get_dummies(df[colname], prefix=colname)
col_dummies.drop(col_dummies.columns[0], axis=1, inplace=True)
df = pd.concat([df, col_dummies], axis=1)
df.drop( colname, axis = 1, inplace = True )
return df`
No, it is not RESTful. The only reason why you should be putting a verb (force_delete
) into the URI is if you would need to overload GET/POST methods in an environment where PUT/DELETE methods are not available. Judging from your use of the DELETE method, this is not the case.
HTTP error code 409/Conflict
should be used for situations where there is a conflict which prevents the RESTful service to perform the operation, but there is still a chance that the user might be able to resolve the conflict himself. A pre-deletion confirmation (where there are no real conflicts which would prevent deletion) is not a conflict per se, as nothing prevents the API from performing the requested operation.
As Alex said (I don't know who downvoted him, he is correct), this should be handled in the UI, because a RESTful service as such just processes requests and should be therefore stateless (i.e. it must not rely on confirmations by holding any server-side information about of a request).
Two examples how to do this in UI would be to:
(*) Please note that HTML versions prior to 5 do not support PUT and DELETE HTTP methods natively, however most modern browsers can do these two methods via AJAX calls. See this thread for details about cross-browser support.
Update (based on additional investigation and discussions):
The scenario where the service would require the force_delete=true
flag to be present violates the uniform interface as defined in Roy Fielding's dissertation. Also, as per HTTP RFC, the DELETE method may be overridden on the origin server (client), implying that this is not done on the target server (service).
So once the service receives a DELETE request, it should process it without needing any additional confirmation (regardless if the service actually performs the operation).
Using opencv-python is faster for more operation on image:
import cv2
import matplotlib.pyplot as plt
im = cv2.imread('image.jpg')
im_resized = cv2.resize(im, (224, 224), interpolation=cv2.INTER_LINEAR)
plt.imshow(cv2.cvtColor(im_resized, cv2.COLOR_BGR2RGB))
plt.show()
Contrary to the suggestions by some of the other answers, using the DllImport
attribute is still the correct approach.
I honestly don't understand why you can't do just like everyone else in the world and specify a relative path to your DLL. Yes, the path in which your application will be installed differs on different people's computers, but that's basically a universal rule when it comes to deployment. The DllImport
mechanism is designed with this in mind.
In fact, it isn't even DllImport
that handles it. It's the native Win32 DLL loading rules that govern things, regardless of whether you're using the handy managed wrappers (the P/Invoke marshaller just calls LoadLibrary
). Those rules are enumerated in great detail here, but the important ones are excerpted here:
Before the system searches for a DLL, it checks the following:
- If a DLL with the same module name is already loaded in memory, the system uses the loaded DLL, no matter which directory it is in. The system does not search for the DLL.
- If the DLL is on the list of known DLLs for the version of Windows on which the application is running, the system uses its copy of the known DLL (and the known DLL's dependent DLLs, if any). The system does not search for the DLL.
If
SafeDllSearchMode
is enabled (the default), the search order is as follows:
- The directory from which the application loaded.
- The system directory. Use the
GetSystemDirectory
function to get the path of this directory.- The 16-bit system directory. There is no function that obtains the path of this directory, but it is searched.
- The Windows directory. Use the
GetWindowsDirectory
function to get the path of this directory.- The current directory.
- The directories that are listed in the
PATH
environment variable. Note that this does not include the per-application path specified by the App Paths registry key. The App Paths key is not used when computing the DLL search path.
So, unless you're naming your DLL the same thing as a system DLL (which you should obviously not be doing, ever, under any circumstances), the default search order will start looking in the directory from which your application was loaded. If you place the DLL there during the install, it will be found. All of the complicated problems go away if you just use relative paths.
Just write:
[DllImport("MyAppDll.dll")] // relative path; just give the DLL's name
static extern bool MyGreatFunction(int myFirstParam, int mySecondParam);
But if that doesn't work for whatever reason, and you need to force the application to look in a different directory for the DLL, you can modify the default search path using the SetDllDirectory
function.
Note that, as per the documentation:
After calling
SetDllDirectory
, the standard DLL search path is:
- The directory from which the application loaded.
- The directory specified by the
lpPathName
parameter.- The system directory. Use the
GetSystemDirectory
function to get the path of this directory.- The 16-bit system directory. There is no function that obtains the path of this directory, but it is searched.
- The Windows directory. Use the
GetWindowsDirectory
function to get the path of this directory.- The directories that are listed in the
PATH
environment variable.
So as long as you call this function before you call the function imported from the DLL for the first time, you can modify the default search path used to locate DLLs. The benefit, of course, is that you can pass a dynamic value to this function that is computed at run-time. That isn't possible with the DllImport
attribute, so you will still use a relative path (the name of the DLL only) there, and rely on the new search order to find it for you.
You'll have to P/Invoke this function. The declaration looks like this:
[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern bool SetDllDirectory(string lpPathName);
It doesn't. There's a vague equivalent:
mycol VARCHAR(10) NOT NULL CHECK (mycol IN('Useful', 'Useless', 'Unknown'))
kue is the only message queue you would ever need
No, the dataType
option is for parsing the received data.
To post JSON, you will need to stringify it yourself via JSON.stringify
and set the processData
option to false
.
$.ajax({
url: url,
type: "POST",
data: JSON.stringify(data),
processData: false,
contentType: "application/json; charset=UTF-8",
complete: callback
});
Note that not all browsers support the JSON
object, and although jQuery has .parseJSON
, it has no stringifier included; you'll need another polyfill library.
One angle not so far mentioned is tool sets used for editing the code.
Using Visual Studio Code along with the Extension from lukehoban called Go
will do some auto-magic for you. The Go extension automatically runs gofmt
, golint
etc, and removes and adds import
entries. So at least that part is now automatic.
I will admit its not 100% of the solution to the question, but however useful enough.
You can use isset()
for this very thing.
$myArr = array("Name" => "Jonathan");
print (isset($myArr["Name"])) ? "Exists" : "Doesn't Exist" ;
i am very new to this website. I am an undergraduate student, doing my Bachelor Of Computer Application. I am doing a simple program in Visual Studio using C# and I came across the same problem, how to check whether a button is clicked? I wanted to do this,
if(-button1 is clicked-) then
{
this should happen;
}
if(-button2 is clicked-) then
{
this should happen;
}
I didn't know what to do, so I tried searching for the solution in the internet. I got many solutions which didn't help me. So, I tried something on my own and did this,
int i;
private void button1_Click(object sender, EventArgs e)
{
i = 1;
label3.Text = "Principle";
label4.Text = "Rate";
label5.Text = "Time";
label6.Text = "Simple Interest";
}
private void button2_Click(object sender, EventArgs e)
{
i = 2;
label3.Text = "SI";
label4.Text = "Rate";
label5.Text = "Time";
label6.Text = "Principle";
}
private void button5_Click(object sender, EventArgs e)
{
try
{
if (i == 1)
{
si = (Convert.ToInt32(textBox1.Text) * Convert.ToInt32(textBox2.Text) * Convert.ToInt32(textBox3.Text)) / 100;
textBox4.Text = Convert.ToString(si);
}
if (i == 2)
{
p = (Convert.ToInt32(textBox1.Text) * 100) / (Convert.ToInt32(textBox2.Text) * Convert.ToInt32(textBox3.Text));
textBox4.Text = Convert.ToString(p);
}
I declared a variable "i" and assigned it with different values in different buttons and checked the value of i in the if function. It worked. Give your suggestions if any. Thank you.
The parameter has this syntax:
{minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
So your example of '1.2-2'
means:
You've nearly got it. The problem is that the Class Under Test (CUT) is not built for unit testing - it has not really been TDD'd.
Think of it like this…
In the unit test
@Spy
on it@Mock
all of the other class/service/database (i.e. external dependencies) In order to avoid executing code that you are not strictly testing, you could abstract that code away into something that can be @Mock
ed.
In this very simple example, a function that creates an object will be difficult to test
public void doSomethingCool(String foo) {
MyObject obj = new MyObject(foo);
// can't do much with obj in a unit test unless it is returned
}
But a function that uses a service to get MyObject is easy to test, as we have abstracted the difficult/impossible to test code into something that makes this method testable.
public void doSomethingCool(String foo) {
MyObject obj = MyObjectService.getMeAnObject(foo);
}
as MyObjectService can be mocked and also verified that .getMeAnObject() is called with the foo variable.
None of posted solutions worked for me. Workaround, which worked:
create a run.bat
and put inside
powershell.exe -file "C:\...\script.ps1"
then set Action to Program/Script: "C:\...\run.bat"
$timeparts = explode(" ",microtime());
$currenttime = bcadd(($timeparts[0]*1000),bcmul($timeparts[1],1000));
echo $currenttime;
NOTE: PHP5 is required for this function due to the improvements with microtime() and the bc math module is also required (as we’re dealing with large numbers, you can check if you have the module in phpinfo).
Hope this help you.
I needed to get the number of occurrences of each distinct value. The column contained Region info. The simple SQL query I ended up with was:
SELECT Region, count(*)
FROM item
WHERE Region is not null
GROUP BY Region
Which would give me a list like, say:
Region, count
Denmark, 4
Sweden, 1
USA, 10

If your table is very big, you can also process rows by "small packages" (not all at oce) (laravel doc: Eloquent> Chunking Results )
Post::chunk(200, function($posts)
{
foreach ($posts as $post)
{
// process post here.
}
});
If your sed
allows in place editing via the -i
parameter:
sed -e 's/$/string after each line/' -i filename
If not, you have to make a temporary file:
typeset TMP_FILE=$( mktemp )
touch "${TMP_FILE}"
cp -p filename "${TMP_FILE}"
sed -e 's/$/string after each line/' "${TMP_FILE}" > filename
quick solution could be:
SELECT your_db_column_name from "your_db_schema_name"."your_db_tabel_name";
I have improved batch file with yes or no prompt. If user enter any character except y and n , then it will again prompt user for valid input. It Works for me.
@echo off
:ConfirmBox
set /P c= Are you sure want to contine (y/n)?
if /I "%c%" EQU "Y" (
goto :FnYes
) else if /I "%c%" EQU "N" (
goto :FnNo
) else (
goto :InValid
)
:FnYes
echo You have entered Y
goto :END
:FnNo
echo You have entered N
goto :END
:InValid
echo Invalid selection. Enter Y or N
goto :ConfirmBox
:END
pause
exit
/I in if condition will validate both lowercase and uppercase characters.
Emitting handbuilt html like this is probably the best way so long as the markup isn't too complicated. The stringbuilder only starts to pay you back in terms of efficiency after about three concatenations, so for really simple stuff string + string will do.
Other than that you can start to use the html controls (System.Web.UI.HtmlControls) and render them, that way you can sometimes inherit them and make your own clasess for complex conditional layout.
if you need to add a date-time to your backup file name (Centos7) use the following:
/usr/bin/mysqldump -u USER -pPASSWD DBNAME | gzip > ~/backups/db.$(date +%F.%H%M%S).sql.gz
this will create the file: db.2017-11-17.231537.sql.gz
In order to keep a POD running it should to be performing certain task, otherwise Kubernetes will find it unnecessary, therefore it stops. There are many ways to keep a POD running.
I have faced similar problems when I needed a POD just to run continuously without doing any useful operation. The following are the two ways those worked for me:
Although the first option is easier than the second one and may suffice the requirement, it is not the best option. As, there is a limit as far as the number of seconds you are going to assign in the sleep command. But a container with infinite loop running inside it never exits.
However, I will describe both the ways(Considering you are running busybox container):
1. Sleep Command
apiVersion: v1
kind: Pod
metadata:
name: busybox
labels:
app: busybox
spec:
containers:
- name: busybox
image: busybox
ports:
- containerPort: 80
command: ["/bin/sh", "-ec", "sleep 1000"]
nodeSelector:
beta.kubernetes.io/os: linux
2. Infinite Loop
apiVersion: v1
kind: Pod
metadata:
name: busybox
labels:
app: busybox
spec:
containers:
- name: busybox
image: busybox
ports:
- containerPort: 80
command: ["/bin/sh", "-ec", "while :; do echo '.'; sleep 5 ; done"]
nodeSelector:
beta.kubernetes.io/os: linux
Run the following command to run the pod:
kubectl apply -f <pod-yaml-file-name>.yaml
Hope it helps!
Here is a fully worked example based on the top voted answer, which is:
int timeout = 1000;
var task = SomeOperationAsync();
if (await Task.WhenAny(task, Task.Delay(timeout)) == task) {
// task completed within timeout
} else {
// timeout logic
}
The main advantage of the implementation in this answer is that generics have been added, so the function (or task) can return a value. This means that any existing function can be wrapped in a timeout function, e.g.:
Before:
int x = MyFunc();
After:
// Throws a TimeoutException if MyFunc takes more than 1 second
int x = TimeoutAfter(MyFunc, TimeSpan.FromSeconds(1));
This code requires .NET 4.5.
using System;
using System.Threading;
using System.Threading.Tasks;
namespace TaskTimeout
{
public static class Program
{
/// <summary>
/// Demo of how to wrap any function in a timeout.
/// </summary>
private static void Main(string[] args)
{
// Version without timeout.
int a = MyFunc();
Console.Write("Result: {0}\n", a);
// Version with timeout.
int b = TimeoutAfter(() => { return MyFunc(); },TimeSpan.FromSeconds(1));
Console.Write("Result: {0}\n", b);
// Version with timeout (short version that uses method groups).
int c = TimeoutAfter(MyFunc, TimeSpan.FromSeconds(1));
Console.Write("Result: {0}\n", c);
// Version that lets you see what happens when a timeout occurs.
try
{
int d = TimeoutAfter(
() =>
{
Thread.Sleep(TimeSpan.FromSeconds(123));
return 42;
},
TimeSpan.FromSeconds(1));
Console.Write("Result: {0}\n", d);
}
catch (TimeoutException e)
{
Console.Write("Exception: {0}\n", e.Message);
}
// Version that works on tasks.
var task = Task.Run(() =>
{
Thread.Sleep(TimeSpan.FromSeconds(1));
return 42;
});
// To use async/await, add "await" and remove "GetAwaiter().GetResult()".
var result = task.TimeoutAfterAsync(TimeSpan.FromSeconds(2)).
GetAwaiter().GetResult();
Console.Write("Result: {0}\n", result);
Console.Write("[any key to exit]");
Console.ReadKey();
}
public static int MyFunc()
{
return 42;
}
public static TResult TimeoutAfter<TResult>(
this Func<TResult> func, TimeSpan timeout)
{
var task = Task.Run(func);
return TimeoutAfterAsync(task, timeout).GetAwaiter().GetResult();
}
private static async Task<TResult> TimeoutAfterAsync<TResult>(
this Task<TResult> task, TimeSpan timeout)
{
var result = await Task.WhenAny(task, Task.Delay(timeout));
if (result == task)
{
// Task completed within timeout.
return task.GetAwaiter().GetResult();
}
else
{
// Task timed out.
throw new TimeoutException();
}
}
}
}
Caveats
Having given this answer, its generally not a good practice to have exceptions thrown in your code during normal operation, unless you absolutely have to:
Only use this code if you absolutely cannot alter the function you are calling so it times out after a specific TimeSpan
.
This answer is really only applicable when dealing with 3rd party library libraries that you simply cannot refactor to include a timeout parameter.
How to write robust code
If you want to write robust code, the general rule is this:
Every single operation that could potentially block indefinitely, must have a timeout.
If you do not observe this rule, your code will eventually hit an operation that fails for some reason, then it will block indefinitely, and your app has just permanently hung.
If there was a reasonable timeout after some time, then your app would hang for some extreme amount of time (e.g. 30 seconds) then it would either display an error and continue on its merry way, or retry.
The WCF API in .NET handles missing parameters by returning an HTTP 404
"Endpoint Not Found" error, when using the webHttpBinding.
The 404 Not Found
can make sense if you consider your web service method name together with its parameter signature. That is, if you expose a web service method LoginUser(string, string)
and you request LoginUser(string)
, the latter is not found.
Basically this would mean that the web service method you are calling, together with the parameter signature you specified, cannot be found.
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
The 400 Bad Request
, as Gert suggested, remains a valid response code, but I think it is normally used to indicate lower-level problems. It could easily be interpreted as a malformed HTTP request, maybe missing or invalid HTTP headers, or similar.
10.4.1 400 Bad Request
The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.
YaLinqo library* is well suited for this sort of task. It's a port of LINQ from .NET which fully supports values and keys in all callbacks and resembles SQL. For example:
$mapped_array = from($test_array)
->select(function ($v, $k) { return "$k loves $v"; })
->toArray();
or just:
$mapped_iterator = from($test_array)->select('"$k loves $v"');
Here, '"$k loves $v"'
is a shortcut for full closure syntax which this library supports. toArray()
in the end is optional. The method chain returns an iterator, so if the result just needs to be iterated over using foreach
, toArray
call can be removed.

Case matters
I manually added a submodule :k3b-geohelper
to the
settings.gradle
file
include ':app', ':k3b-geohelper'
and everthing works fine on my mswindows build system
When i pushed the update to github the fdroid build system failed with
Cannot evaluate module k3b-geohelper : Configuration with name 'default' not found
The final solution was that the submodule folder was named k3b-geoHelper
not k3b-geohelper

The best way which works now on all Major Browsers is the following Script:

window.addEventListener("online", isOnline, false);
window.addEventListener("offline", isOffline, false);
}
else {

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 usually use this code
Sub AutoFilter_Remove()
Sheet1.AutoFilterMode = False 'Change Sheet1 to the relevant sheet
'Alternatively: Worksheets("[Your Sheet Name]").AutoFilterMode = False
End Sub
Just to add to the answers, App Server Apache Geronimo 3.0 uses Tomcat 7 as the web server, and in that environment the file server.xml is located at
<%GERONIMO_HOME%>/var/catalina/server.xml

The configuration does take effect even when the Geronimo Console at Application Server->WebServer->TomcatWebConnector->maxPostSize
still displays 2097152 (the default value)
This does not need jquery, you could set a variable inside the if and use it in html or pass it thru your template system if any
<?php
$showDivFlag=false
$query3 = mysql_query($query3);
$numrows = mysql_num_rows($query3);
if ($numrows > 0){
$fvisit = mysql_fetch_array($result3);
$showDivFlag=true;
}else {
}
?>
later in html
<div id="results" <?php if ($showDivFlag===false){?>style="display:none"<?php } ?>>

It has to do with the Normal Form for the SQL language. IF
statements can, by definition, only take a single SQL statement. However, there is a special kind of SQL statement which can contain multiple SQL statements, the BEGIN-END
block.
If you omit the BEGIN-END
block, your SQL will run fine, but it will only execute the first statement as part of the IF
.
Basically, this:
IF @Term = 3
INSERT INTO @Classes
SELECT
XXXXXX
FROM XXXX blah blah blah
is equivalent to the same thing with the BEGIN-END
block, because you are only executing a single statement. However, for the same reason that not including the curly-braces on an IF
statement in a C-like language is a bad idea, it is always preferable to use BEGIN
and END
.
If you've opened a table and you want to clear an existing value to NULL, click on the value, and press Ctrl

Let's use some java 8 feature:

If you need to store the numbers you can collect them into a collection eg:
List numbers = IntStream.iterate(10, x -> x + 10).limit(5)
.boxed()
.collect(Collectors.toList());
And some delay added:
IntStream.iterate(10, x -> x + 10).limit(5)
.forEach(x -> {
System.out.println(x);
try {
Thread.sleep(2000);
