esModuleInterop
generates the helpers outlined in the docs. Looking at the generated code, we can see exactly what these do:
//ts
import React from 'react'
//js
var __importDefault = (this && this.__importDefault) || function (mod) {
return (mod && mod.__esModule) ? mod : { "default": mod };
};
Object.defineProperty(exports, "__esModule", { value: true });
var react_1 = __importDefault(require("react"));
__importDefault
: If the module is not an es
module then what is returned by require becomes the default. This means that if you use default import on a commonjs
module, the whole module is actually the default.
__importStar
is best described in this PR:
TypeScript treats a namespace import (i.e.
import * as foo from "foo"
) as equivalent toconst foo = require("foo")
. Things are simple here, but they don't work out if the primary object being imported is a primitive or a value with call/construct signatures. ECMAScript basically says a namespace record is a plain object.Babel first requires in the module, and checks for a property named
__esModule
. If__esModule
is set totrue
, then the behavior is the same as that of TypeScript, but otherwise, it synthesizes a namespace record where:
- All properties are plucked off of the require'd module and made available as named imports.
- The originally require'd module is made available as a default import.
So we get this:
// ts
import * as React from 'react'
// emitted js
var __importStar = (this && this.__importStar) || function (mod) {
if (mod && mod.__esModule) return mod;
var result = {};
if (mod != null) for (var k in mod) if (Object.hasOwnProperty.call(mod, k)) result[k] = mod[k];
result["default"] = mod;
return result;
};
Object.defineProperty(exports, "__esModule", { value: true });
var React = __importStar(require("react"));
allowSyntheticDefaultImports
is the companion to all of this, setting this to false will not change the emitted helpers (both of them will still look the same). But it will raise a typescript error if you are using default import for a commonjs module. So this import React from 'react'
will raise the error Module '".../node_modules/@types/react/index"' has no default export.
if allowSyntheticDefaultImports
is false
.
I got below error :
Found the synthetic property @collapse. Please include either "BrowserAnimationsModule" or "NoopAnimationsModule" in your application.
I follow the accepted answer by Ploppy and it resolved my problem.
Here are the steps:
1.
import { trigger, state, style, transition, animate } from '@angular/animations';
Or
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
2. Define the same in the import array in the root module.
It will resolve the error. Happy coding!!
I have the following in a types.ts
file for html input, select, and textarea:
export type InputChangeEventHandler = React.ChangeEventHandler<HTMLInputElement>
export type TextareaChangeEventHandler = React.ChangeEventHandler<HTMLTextAreaElement>
export type SelectChangeEventHandler = React.ChangeEventHandler<HTMLSelectElement>
Then import them:
import { InputChangeEventHandler } from '../types'
Then use them:
const updateName: InputChangeEventHandler = (event) => {
// Do something with `event.currentTarget.value`
}
const updateBio: TextareaChangeEventHandler = (event) => {
// Do something with `event.currentTarget.value`
}
const updateSize: SelectChangeEventHandler = (event) => {
// Do something with `event.currentTarget.value`
}
Then apply the functions on your markup (replacing ...
with other necessary props):
<input onChange={updateName} ... />
<textarea onChange={updateName} ... />
<select onChange={updateSize} ... >
// ...
</select>
You need to define propTypes
as a static getter if you want it inside the class declaration:
static get propTypes() {
return {
children: PropTypes.any,
onClickOut: PropTypes.func
};
}
If you want to define it as an object, you need to define it outside the class, like this:
IxClickOut.propTypes = {
children: PropTypes.any,
onClickOut: PropTypes.func,
};
Also it's better if you import prop types from prop-types
, not react
, otherwise you'll see warnings in console (as preparation for React 16):
import PropTypes from 'prop-types';
I've come across this problem on Typescript Version 3.8.3.
Intellisense is the best thing we could have but for me, the auto-import feature doesn't seem to work either. I've tried installing an extension even though auto-import didn't work. I've rechecked all the settings related to extensions. Finally, the auto-import feature started working when I clear the cache, from
C:\Users\username\AppData\Roaming\Code\Cache
& reload the VSCode
Note: AppData can only be visible in username if you select, Show (Hidden Items) from (View) Menu.
In some cases, we may end up thinking there is an import related error, while in actuality, unknowingly we might be coding using deprecated features or APIs in angular.
For example: if you're trying to code something like this
constructor (http: Http) {
//...}
Where Http is already deprecated and replaced with HttpClient in the newer version, so we may end up thinking an error related to this might be related to the auto-import error. For more information, you can refer Deprecated APIs and Features
Nothing wrong with Ryan's answer, but for people who came here looking for how to maintain a one-class-per-file structure while still using ES6 namespaces correctly please refer to this helpful resource from Microsoft.
One thing that's unclear to me after reading the doc is: how to import the entire (merged) module with a single import
.
Edit Circling back to update this answer. A few approaches to namespacing emerge in TS.
All module classes in one file.
export namespace Shapes {
export class Triangle {}
export class Square {}
}
Import files into namespace, and reassign
import { Triangle as _Triangle } from './triangle';
import { Square as _Square } from './square';
export namespace Shapes {
export const Triangle = _Triangle;
export const Square = _Square;
}
Barrels
// ./shapes/index.ts
export { Triangle } from './triangle';
export { Square } from './square';
// in importing file:
import * as Shapes from './shapes/index.ts';
// by node module convention, you can ignore '/index.ts':
import * as Shapes from './shapes';
let myTriangle = new Shapes.Triangle();
A final consideration. You could namespace each file
// triangle.ts
export namespace Shapes {
export class Triangle {}
}
// square.ts
export namespace Shapes {
export class Square {}
}
But as one imports two classes from the same namespace, TS will complain there's a duplicate identifier. The only solution as this time is to then alias the namespace.
import { Shapes } from './square';
import { Shapes as _Shapes } from './triangle';
// ugh
let myTriangle = new _Shapes.Shapes.Triangle();
This aliasing is absolutely abhorrent, so don't do it. You're better off with an approach above. Personally, I prefer the 'barrel'.
Using arrow function :
You must install stage-2:
npm install babel-preset-stage-2 :
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
value=0
}
}
changeValue = (data) => (e) => {
alert(data); //10
this.setState({ [value]: data })
}
render() {
const data = 10;
return (
<div>
<input type="button" onClick={this.changeValue(data)} />
</div>
);
}
}
export default App;
None of the provided examples here work for the generic case, which are N dimensional matrices. Anything using "rows" assumes theres columns and rows only, a 4 dimensional matrix might have more.
Here is some example code copying a non-continuous N-dimensional matrix into a continuous memory stream - then converts it back into a Cv::Mat
#include <iostream>
#include <cstdint>
#include <cstring>
#include <opencv2/opencv.hpp>
int main(int argc, char**argv)
{
if ( argc != 2 )
{
std::cerr << "Usage: " << argv[0] << " <Image_Path>\n";
return -1;
}
cv::Mat origSource = cv::imread(argv[1],1);
if (!origSource.data) {
std::cerr << "Can't read image";
return -1;
}
// this will select a subsection of the original source image - WITHOUT copying the data
// (the header will point to a region of interest, adjusting data pointers and row step sizes)
cv::Mat sourceMat = origSource(cv::Range(origSource.size[0]/4,(3*origSource.size[0])/4),cv::Range(origSource.size[1]/4,(3*origSource.size[1])/4));
// correctly copy the contents of an N dimensional cv::Mat
// works just as fast as copying a 2D mat, but has much more difficult to read code :)
// see http://stackoverflow.com/questions/18882242/how-do-i-get-the-size-of-a-multi-dimensional-cvmat-mat-or-matnd
// copy this code in your own cvMat_To_Char_Array() function which really OpenCV should provide somehow...
// keep in mind that even Mat::clone() aligns each row at a 4 byte boundary, so uneven sized images always have stepgaps
size_t totalsize = sourceMat.step[sourceMat.dims-1];
const size_t rowsize = sourceMat.step[sourceMat.dims-1] * sourceMat.size[sourceMat.dims-1];
size_t coordinates[sourceMat.dims-1] = {0};
std::cout << "Image dimensions: ";
for (int t=0;t<sourceMat.dims;t++)
{
// calculate total size of multi dimensional matrix by multiplying dimensions
totalsize*=sourceMat.size[t];
std::cout << (t>0?" X ":"") << sourceMat.size[t];
}
// Allocate destination image buffer
uint8_t * imagebuffer = new uint8_t[totalsize];
size_t srcptr=0,dptr=0;
std::cout << std::endl;
std::cout << "One pixel in image has " << sourceMat.step[sourceMat.dims-1] << " bytes" <<std::endl;
std::cout << "Copying data in blocks of " << rowsize << " bytes" << std::endl ;
std::cout << "Total size is " << totalsize << " bytes" << std::endl;
while (dptr<totalsize) {
// we copy entire rows at once, so lowest iterator is always [dims-2]
// this is legal since OpenCV does not use 1 dimensional matrices internally (a 1D matrix is a 2d matrix with only 1 row)
std::memcpy(&imagebuffer[dptr],&(((uint8_t*)sourceMat.data)[srcptr]),rowsize);
// destination matrix has no gaps so rows follow each other directly
dptr += rowsize;
// src matrix can have gaps so we need to calculate the address of the start of the next row the hard way
// see *brief* text in opencv2/core/mat.hpp for address calculation
coordinates[sourceMat.dims-2]++;
srcptr = 0;
for (int t=sourceMat.dims-2;t>=0;t--) {
if (coordinates[t]>=sourceMat.size[t]) {
if (t==0) break;
coordinates[t]=0;
coordinates[t-1]++;
}
srcptr += sourceMat.step[t]*coordinates[t];
}
}
// this constructor assumes that imagebuffer is gap-less (if not, a complete array of step sizes must be given, too)
cv::Mat destination=cv::Mat(sourceMat.dims, sourceMat.size, sourceMat.type(), (void*)imagebuffer);
// and just to proof that sourceImage points to the same memory as origSource, we strike it through
cv::line(sourceMat,cv::Point(0,0),cv::Point(sourceMat.size[1],sourceMat.size[0]),CV_RGB(255,0,0),3);
cv::imshow("original image",origSource);
cv::imshow("partial image",sourceMat);
cv::imshow("copied image",destination);
while (cv::waitKey(60)!='q');

I ran into this problem yesterday, so I created a React-friendly solution.
Check out react-native-listener. It's working very well so far. Feedback appreciated.

This might not really answer the question, but just in case someone just need to quickly send a string value to a function that require a NSArray parameter.
NSArray *data = @[@"The String Value"];
if you need to send more than just 1 string value, you could also use
NSArray *data = @[@"The String Value", @"Second String", @"Third etc"];
then you can send it to the function like below
theFunction(data);
If you're using SwiftUI
If you're updating from a previous version of Xcode 11, there are some changes to the SceneDelegate
willConnectTo session: options connectionOptions
initialization:
The main window
is now initialized using UIWindow(windowScene: windowScene)
, where it use to be UIWindow(frame: UIScreen.main.bounds)
On previous version:
let window = UIWindow(frame: UIScreen.main.bounds)
window.rootViewController = UIHostingController(rootView: ContentView())
self.window = window
window.makeKeyAndVisible()
In new version:
if let windowScene = scene as? UIWindowScene {
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: ContentView())
self.window = window
window.makeKeyAndVisible()
}
I tried following instructions given in most of the comments on this thread, including the chosen answer but the error persisted. I did some research and found this page that gave a solution that helped me out (okay, with some guessing though of my part).
So what I did is that I replaced the version number in the maven surefire plugin as follows:
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>3.0.0-M1</version>
I hope this helps!
I spend a hour finding out what was wrong.. But Clean Project did the trick.
Build -> Clean All
The accepted solution is probably also working.. but this was enough for me.
double *ptr = malloc(sizeof(double *) * TIME); /* ... */ for(tcount = 0; tcount <= TIME; tcount++) ^^
<=
to <
or alloc
SIZE + 1
elementsmalloc
is wrong, you'll want sizeof(double)
instead of
sizeof(double *)
ouah
comments, although not directly linked to your corruption problem, you're using *(ptr+tcount)
without initializing itptr[tcount]
instead of *(ptr + tcount)
malloc
+ free
since you already know SIZE
The other answers are all good. For Xilinx FPGA designs, it is best not to use global reset lines, and use initial
blocks for reset conditions for most logic. Here is the white paper from Ken Chapman (Xilinx FPGA guru)
http://japan.xilinx.com/support/documentation/white_papers/wp272.pdf
SIGABRT is, as stated in other answers, a general uncaught exception. You should definitely learn a little bit more about Objective-C. The problem is probably in your UITableViewDelegate method didSelectRowAtIndexPath.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
I can't tell you much more until you show us something of the code where you handle the table data source and delegate methods.
If anybody is looking for a swift version:
1) Create a custom class for your data
class customData: NSObject, NSCoding {
let name : String
let url : String
let desc : String
init(tuple : (String,String,String)){
self.name = tuple.0
self.url = tuple.1
self.desc = tuple.2
}
func getName() -> String {
return name
}
func getURL() -> String{
return url
}
func getDescription() -> String {
return desc
}
func getTuple() -> (String,String,String) {
return (self.name,self.url,self.desc)
}
required init(coder aDecoder: NSCoder) {
self.name = aDecoder.decodeObjectForKey("name") as! String
self.url = aDecoder.decodeObjectForKey("url") as! String
self.desc = aDecoder.decodeObjectForKey("desc") as! String
}
func encodeWithCoder(aCoder: NSCoder) {
aCoder.encodeObject(self.name, forKey: "name")
aCoder.encodeObject(self.url, forKey: "url")
aCoder.encodeObject(self.desc, forKey: "desc")
}
}
2) To save data use following function:
func saveData()
{
let data = NSKeyedArchiver.archivedDataWithRootObject(custom)
let defaults = NSUserDefaults.standardUserDefaults()
defaults.setObject(data, forKey:"customArray" )
}
3) To retrieve:
if let data = NSUserDefaults.standardUserDefaults().objectForKey("customArray") as? NSData
{
custom = NSKeyedUnarchiver.unarchiveObjectWithData(data) as! [customData]
}
Note: Here I am saving and retrieving an array of the custom class objects.
One thing want to add is that if a property is declared as @dynamic it will not occupy memory (I confirmed with allocation instrument). A consequence is that you can declare property in class category.
In the code you posted, you're sending the setDownloadURL:
setter to ClassA
— that is, the class itself. You want to set the property of an instance.
I'm just speculating:
I think that the variable defined in the ivars allocates the space right in the object. This prevents you from creating accessors because you can't give an array by value to a function but only through a pointer. Therefore you have to use a pointer in the ivars:
int *doubleDigits;
And then allocate the space for it in the init-method:
@synthesize doubleDigits;
- (id)init {
if (self = [super init]) {
doubleDigits = malloc(sizeof(int) * 10);
/*
* This works, but is dangerous (forbidden) because bufferDoubleDigits
* gets deleted at the end of -(id)init because it's on the stack:
* int bufferDoubleDigits[] = {1,2,3,4,5,6,7,8,9,10};
* [self setDoubleDigits:bufferDoubleDigits];
*
* If you want to be on the safe side use memcpy() (needs #include <string.h>)
* doubleDigits = malloc(sizeof(int) * 10);
* int bufferDoubleDigits[] = {1,2,3,4,5,6,7,8,9,10};
* memcpy(doubleDigits, bufferDoubleDigits, sizeof(int) * 10);
*/
}
return self;
}
- (void)dealloc {
free(doubleDigits);
[super dealloc];
}
In this case the interface looks like this:
@interface MyClass : NSObject {
int *doubleDigits;
}
@property int *doubleDigits;
Edit:
I'm really unsure wether it's allowed to do this, are those values really on the stack or are they stored somewhere else? They are probably stored on the stack and therefore not safe to use in this context. (See the question on initializer lists)
int bufferDoubleDigits[] = {1,2,3,4,5,6,7,8,9,10};
[self setDoubleDigits:bufferDoubleDigits];
select replace(wm_concat(new),',','-') exp_res from (select distinct initcap(substr(name,decode(level,1,1,instr(name,'-',1,level-1)+1),decode(level,(length(name)-length(replace(name,'-','')))+1,9999,instr(name,'-',1,level)-1-decode(level,1,0,instr(name,'-',1,level-1))))) new from table;
connect by level<= (select (length(name)-length(replace(name,'-','')))+1 from table));
I'd try to search for the solution by google and the string Python for statement, it is as simple as that. The first link says everything. (A great forum, really, but its usage seems to look sometimes like the usage of the Microsoft understanding of all their GUI products' benefits: windows inside, idiots outside.)
if, for any reasons, you don't want to add a wrapper (in my first case it was for <tr/>
components), you can use a functionnal component.
Instead of having a single components/MyCompo.vue
you will have few files in a components/MyCompo
folder :
components/MyCompo/index.js
components/MyCompo/File.vue
components/MyCompo/Avatar.vue
With this structure, the way you call your component won't change.
components/MyCompo/index.js
file content :
import File from './File';
import Avatar from './Avatar';
const commonSort=(a,b)=>b-a;
export default {
functional: true,
name: 'MyCompo',
props: [ 'someProp', 'plopProp' ],
render(createElement, context) {
return [
createElement( File, { props: Object.assign({light: true, sort: commonSort},context.props) } ),
createElement( Avatar, { props: Object.assign({light: false, sort: commonSort},context.props) } )
];
}
};
And if you have some function or data used in both templates, passed them as properties and that's it !
I let you imagine building list of components and so much features with this pattern.

I was having trouble converting struct to JSON, sending it as response from Golang, then, later catch the same in JavaScript via Ajax.
Wasted a lot of time, so posting solution here.
In Go:

The HttpParams
interface isn't there for specifying query string parameters, it's for specifying runtime behaviour of the HttpClient

If you want to pass query string parameters, you need to assemble them on the URL yourself, e.g.

You should use the csv
module to read the tab-separated value file. Do not read it into memory in one go. Each row you read has all the information you need to write rows to the output CSV file, after all. Keep the output file open throughout.

tsvin = csv.reader(tsvin, delimiter='\t')
csvout = csv.writer(csvout)
for row in tsvin:
count = int(row[4])
if count > 0:
csvout.writerows([row[2:4] for _ in range(count)])
or, using the itertools
module to do the repeating with itertools.repeat()
:
from itertools import repeat
import csv
with open('sample.txt', newline='') as tsvin, open('new.csv', 'w', newline='') as csvout:
tsvin = csv.reader(tsvin, delimiter='\t')
csvout = csv.writer(csvout)
for row in tsvin:

if count > 0:

TAB has a specific meaning in PowerShell. It's for command completion. So if you enter "getch" and then type a TAB. It changes what you typed into "GetChildItem" (it corrects the case, even though that's unnecessary).
From your question, it looks like TAB completion and command completion would overload the TAB key. I'm pretty sure the PowerShell designers didn't want that.

You can do this concisely using the toolbelt vg. It's a light layer on top of numpy and it supports single values and stacked vectors.

mag1 = np.linalg.norm(x)
mag2 = vg.magnitude(x)
print mag1 == mag2

JavaScript running in a browser doesn't generally have access to the local file system. That's outside the sandbox. So I think the answer is no.
if you do this:
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
.
You may get this error:
E: Unable to locate package lib32bz2-1.0
E: Couldn't find any package by glob 'lib32bz2-1.0'
E: Couldn't find any package by regex 'lib32bz2-1.0'
So i suggest just doing this:
sudo apt-get install lib32stdc++6

Here's an example that worked for me. I had a list of about 500 specific files in a text file, contained in about 100 different folders, that I was supposed to copy over to a backup location in case those files were needed later. The text file contained full path and file name, one per line. In my case, I wanted to strip off the Drive letter and first sub-folder name from each file name. I wanted to copy all these files to a similar folder structure under another root destination folder I specified. I hope other users find this helpful.

If you are using SQL Server (starting with 2008), choose one of this:
Well, you can actually send data via JavaScript - but you should know that this is the #1 exploit source in web pages as it's XSS :)
I personally would suggest to use an HTML formular instead and modify the javascript data on the server side.
But if you want to share between two pages (I assume they are not both on localhost, because that won't make sense to share between two both-backend-driven pages) you will need to specify the CORS headers to allow the browser to send data to the whitelisted domains.
These two links might help you, it shows the example via Node backend, but you get the point how it works:
And, of course, the CORS spec:

Your /home/gnu/bin/c++
seem to require additional flag to link things properly and CMake doesn't know about that.
To use /usr/bin/c++
as your compiler run cmake
with -DCMAKE_CXX_COMPILER=/usr/bin/c++
.
Also, CMAKE_PREFIX_PATH
variable sets destination dir where your project' files should be installed. It has nothing to do with CMake installation prefix and CMake itself already know this.
I personally use interfaces for my models, There hoewver are 3 schools regarding this question, and choosing one is most often based on your requirements:
interface
is a virtual structure that only exists within the context of TypeScript. The TypeScript compiler uses interfaces solely for type-checking purposes. Once your code is transpiled to its target language, it will be stripped from its interfaces - JavaScript isn’t typed.
interface User {
id: number;
username: string;
}
// inheritance
interface UserDetails extends User {
birthdate: Date;
biography?: string; // use the '?' annotation to mark this property as optionnal
}
Mapping server response to an interface
is straight forward if you are using HttpClient
from HttpClientModule
if you are using Angular 4.3.x and above.
getUsers() :Observable<User[]> {
return this.http.get<User[]>(url); // no need for '.map((res: Response) => res.json())'
}
when to use interfaces:
let instance: FooInterface = { ... };
, you risk having semi-instances all over the place.A class
defines the blueprints of an object. They express the logic, methods, and properties these objects will inherit.
class User {
id: number;
username: string;
constructor(id :number, username: string) {
this.id = id;
this.username = username.replace(/^\s+|\s+$/g, ''); // trim whitespaces and new lines
}
}
// inheritance
class UserDetails extends User {
birthdate: Date;
biography?: string;
constructor(id :number, username: string, birthdate:Date, biography? :string ) {
super(id,username);
this.birthdate = ...;
}
}
when to use classes:
With the latest versions of typescript, interfaces and types becoming more similar.
types
do not express logic or state inside your application. It is best to use types when you want to describe some form of information. They can describe varying shapes of data, ranging from simple constructs like strings, arrays, and objects.
Like interfaces, types are only virtual structures that don't transpile to any javascript, they just help the compiler making our life easier.
type User = {
id: number;
username: string;
}
// inheritance
type UserDetails = User & {
birthDate :Date;
biography?:string;
}
when to use types:

The folder structure might be as:
Where there are two Makefiles, each as below;
sample/Makefile
test/Makefile
Now, let us see the content of the Makefiles.
sample/Makefile
export ROOT_DIR=${PWD}
all:
echo ${ROOT_DIR}
$(MAKE) -C test
test/Makefile
all:
echo ${ROOT_DIR}
echo "make test ends here !"
Now, execute the sample/Makefile, as;
cd sample
make
OUTPUT:
echo /home/symphony/sample
/home/symphony/sample
make -C test
make[1]: Entering directory `/home/symphony/sample/test'
echo /home/symphony/sample
/home/symphony/sample
echo "make test ends here !"
make test ends here !
make[1]: Leaving directory `/home/symphony/sample/test'
Explanation, would be that the parent/home directory can be stored in the environment-flag, and can be exported, so that it can be used in all the sub-directory makefiles.
$('#divname').parent().appendTo($("form:first"));
Using this code solved my problem and it worked in every browser, Internet Explorer 7, Firefox 3, and Google Chrome. I start to love jQuery... It's a cool framework.

Angular’s keyvalue
pipe can be used, but unfortunately it sorts by key. Maps already have an order and it would be great to be able to keep it!
We can define out own pipe mapkeyvalue
which preserves the order of items in the map:
import { Pipe, PipeTransform } from '@angular/core';
// Holds a weak reference to its key (here a map), so if it is no longer referenced its value can be garbage collected.
const cache = new WeakMap<ReadonlyMap<any, any>, Array<{ key: any; value: any }>>();
@Pipe({ name: 'mapkeyvalue', pure: true })
export class MapKeyValuePipe implements PipeTransform {
transform<K, V>(input: ReadonlyMap<K, V>): Iterable<{ key: K; value: V }> {
const existing = cache.get(input);
if (existing !== undefined) {
return existing;
}
const iterable = Array.from(input, ([key, value]) => ({ key, value }));
cache.set(input, iterable);
return iterable;
}
}
It can be used like so:
<mat-select>
<mat-option *ngFor="let choice of choicesMap | mapkeyvalue" [value]="choice.key">
{{ choice.value }}
</mat-option>
</mat-select>
This is not possible.
In Python, there really isn't any such thing as a "variable". What Python really has are "names" which can have objects bound to them. It makes no difference to the object what names, if any, it might be bound to. It might be bound to dozens of different names, or none.
Consider this example:
foo = 1
bar = 1
baz = 1
Now, suppose you have the integer object with value 1, and you want to work backwards and find its name. What would you print? Three different names have that object bound to them, and all are equally valid.
In Python, a name is a way to access an object, so there is no way to work with names directly. There might be some clever way to hack the Python bytecodes or something to get the value of the name, but that is at best a parlor trick.
If you know you want print foo
to print "foo"
, you might as well just execute print "foo"
in the first place.
EDIT: I have changed the wording slightly to make this more clear. Also, here is an even better example:
foo = 1
bar = foo
baz = foo
In practice, Python reuses the same object for integers with common values like 0 or 1, so the first example should bind the same object to all three names. But this example is crystal clear: the same object is bound to foo, bar, and baz.

Xcode Workspace vs Project
- What is the difference between the two of them?
Workspace
is a set of projects
- What are they responsible for?
Workspace
is responsible for dependencies between projects.
Project
is responsible for the source code.
- Which one of them should I work with when I'm developing my Apps in team/alone?
You choice should depends on a type of your project. For example if your project relies on CocoaPods dependency manager it creates a workspace.
- Is there anything else I should be aware of in matter of these two files?
A competitor of workspace is cross-project references

One more way of running an R script from the command line would be:
R < scriptName.R --no-save
or with --save
.
See also What's the best way to use R scripts on the command line (terminal)?.
If your array is always sequential and starts at 0, then you can do this:
array[${#array[@]}]='foo'
# gets the length of the array
${#array_name[@]}
If you inadvertently use spaces between the equal sign:
array[${#array[@]}] = 'foo'
Then you will receive an error similar to:
array_name[3]: command not found
You are close you want to use @Html.Raw(str)
@Html.Encode
takes strings and ensures that all the special characters are handled properly. These include characters like spaces.
This should probably be a comment, however, I don't have enough reputation to comment.
I suggest you really use the table (HTML) instead of ion-row and ion-col. Things will not look nice when one of the cell's content is too long.
One worse case looks like this:
| 10 | 20 | 30 | 40 |
| 1 | 2 | 3100 | 41 |

when I create my JLabel and enter the text to it, there is no wordwrap or anything
HTML formatting can be used to cause word wrap in any Swing component that offers styled text. E.G. as demonstrated in this answer.
Working & tested solution, which does not require to delete application:
It looks like AppStore Distribution Provisioning Profile or just iOS Distribution certificate have special permissions and "Could not be verified..." problem does not apply to them. They will always override previous certificate.
In other words: AppStore release will install successfully, even if already installed (testing, adhoc or enterprise) app has been signed by the certificate from different team.
If you are lucky and have previously uploaded app to the AppStore account owned by the same team as in certificate you have a problem with - then things are very simple: just download & install app from AppStore.
When it installs - app certificate will be the same as the one you want to test with and problem goes away.
If your app is not on the AppStore yet - iTunesConnect beta comes to the rescue:
Disclaimer: I did not tested this but since cert an prev are the same as AppStore release, I bet it works:
We can do something like this
DateTime date_temp_from = DateTime.Parse(from.Value); //from.value" is input by user (dd/MM/yyyy)
DateTime date_temp_to = DateTime.Parse(to.Value); //to.value" is input by user (dd/MM/yyyy)
string date_from = date_temp_from.ToString("yyyy/MM/dd HH:mm");
string date_to = date_temp_to.ToString("yyyy/MM/dd HH:mm");

The question is: "Sort Collection". So you can't use Collections.sort(List<T> l, Comparator<? super T> comparator)
.
Some tips:
For Collection type:
Comparator<String> defaultComparator = new Comparator<String>() {
@Override
public int compare(String o1, String o2) {
return o1.compareTo(o2);
}
};
Collection<String> collection = getSomeStringCollection();
String[] strings = collection.toArray(new String[collection.size()]);
Arrays.sort(strings, defaultComparator);
List<String> sortedStrings = Arrays.asList(strings);
Collection<String> collection = getSomeStringCollection();
List<String> list = new ArrayList(collection);
Collections.sort(list, defaultComparator);
collection = list; // if you wish
For List type:
List<String> list = getSomeStringList();
Collections.sort(list, defaultComparator);
For Set type:
Set<String> set = getSomeStringSet();
// Than steps like in 'For Collection type' section or use java.util.TreeSet
// TreeSet sample:
// Sorted using java.lang.Comparable.
Set<String> naturalSorted = new TreeSet(set);
Set<String> set = getSomeStringSet();
Set<String> sortedSet = new TreeSet(defaultComparator);
sortedSet.addAll(set);
Java 8 version. There is java.util.List#sort(Comparator<? super E> c)
method
List<String> list = getSomeStringList();
list.sort(defaultComparator);
or
List<String> list = getSomeStringList();
list.sort((String o1, String o2) -> o1.compareTo(o2));
or for types that implements Comparable:
List<String> list = getSomeStringList();
list.sort(String::compareTo);
ISNA is the best function to use. I just did. I wanted all cells whose value was NOT in an array to conditionally format to a certain color.
=ISNA(VLOOKUP($A2,Sheet1!$A:$D,2,FALSE))
Old question, but I had the same issue. I tried every answer above, nothing worked. What fixed it for me though was removing the domain, and adding it again. I'm using Plesk, and I installed Nginx AFTER the domain was already there.
Did a local backup to /var/www/backups first though. So I could easily copy back the files.

Change hidden field value with checkbox toggle like below...
HTML:
<input type='hidden' value='Unchecked' id="deleteAll" name='anyName'>
<input type="checkbox" onclick="toggle(this)"/> Delete All
Script:
function toggle(obj) {`var $input = $(obj);
if ($input.prop('checked')) {
$('#deleteAll').attr( 'value','Checked');
} else {
$('#deleteAll').attr( 'value','Unchecked');
}
}
Yet another solution for random colors:
function colorize(str) {
for (var i = 0, hash = 0; i < str.length; hash = str.charCodeAt(i++) + ((hash << 5) - hash));
color = Math.floor(Math.abs((Math.sin(hash) * 10000) % 1 * 16777216)).toString(16);
return '#' + Array(6 - color.length + 1).join('0') + color;
}
It's a mixed of things that does the job for me. I used JFreeman Hash function (also an answer in this thread) and Asykäri pseudo random function from here and some padding and math from myself.
I doubt the function produces evenly distributed colors, though it looks nice and does that what it should do.
Step-1: Your Model class
public class RechargeMobileViewModel
{
public string CustomerFullName { get; set; }
public string TelecomSubscriber { get; set; }
public int TotalAmount { get; set; }
public string MobileNumber { get; set; }
public int Month { get; set; }
public List<SelectListItem> getAllDaysList { get; set; }
// Define the list which you have to show in Drop down List
public List<SelectListItem> getAllWeekDaysList()
{
List<SelectListItem> myList = new List<SelectListItem>();
var data = new[]{
new SelectListItem{ Value="1",Text="Monday"},
new SelectListItem{ Value="2",Text="Tuesday"},
new SelectListItem{ Value="3",Text="Wednesday"},
new SelectListItem{ Value="4",Text="Thrusday"},
new SelectListItem{ Value="5",Text="Friday"},
new SelectListItem{ Value="6",Text="Saturday"},
new SelectListItem{ Value="7",Text="Sunday"},
};
myList = data.ToList();
return myList;
}
}
Step-2: Call this method to fill Drop down in your controller Action
namespace MvcVariousApplication.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
RechargeMobileViewModel objModel = new RechargeMobileViewModel();
objModel.getAllDaysList = objModel.getAllWeekDaysList();
return View(objModel);
}
}
}
Step-3: Fill your Drop-Down List of View as follows
@model MvcVariousApplication.Models.RechargeMobileViewModel
@{
ViewBag.Title = "Contact";
}
@Html.LabelFor(model=> model.CustomerFullName)
@Html.TextBoxFor(model => model.CustomerFullName)
@Html.LabelFor(model => model.MobileNumber)
@Html.TextBoxFor(model => model.MobileNumber)
@Html.LabelFor(model => model.TelecomSubscriber)
@Html.TextBoxFor(model => model.TelecomSubscriber)
@Html.LabelFor(model => model.TotalAmount)
@Html.TextBoxFor(model => model.TotalAmount)
@Html.LabelFor(model => model.Month)
@Html.DropDownListFor(model => model.Month, new SelectList(Model.getAllDaysList, "Value", "Text"), "-Select Day-")

I think a really simple answer might be useful here:
return
makes the value (a variable, often) available for use by the caller (for example, to be stored by a function that the function using return
is within). Without return
, your value or variable wouldn't be available for the caller to store/re-use.
print
prints to the screen, but does not make the value or variable available for use by the caller.
(Fully admitting that the more thorough answers are more accurate.)
For brevity, we can understand these two APIs like below:
X.class.isAssignableFrom(Y.class)
If X
and Y
are the same class, or X
is Y
's super class or super interface, return true, otherwise, false.
X.class.isInstance(y)
Say y
is an instance of class Y
, if X
and Y
are the same class, or X
is Y
's super class or super interface, return true, otherwise, false.
This solution worked for me:
I have create Demo.exe using Eclipse RCP.
I have run Demo.exe using C-Drive to same error generate like...
Solution : You might changed your drive for example
C:\Demo.exe to D:\Demo.exe
Step 1 : First Copy/Cut your .exe file like C:\Demo.exe
Step 2 : After Paste another drive like D:\Demo.exe
After executable file launching successfully.
I hope my answer is useful.
No there's not and developers still don't know why google doesn't pay attention to this request!
As you can see in this link it's one of the most popular issues with many stars in google code but still no response from google! You can also add stars to this issue, maybe google hears that!
Try using the not()
method instead of the :not()
selector.
$(".content a").click(function() {
$(".content a").not(this).hide("slow");
});
Use "
instead of "
to escape it.
web.config is an XML file so you should use XML escaping.
connectionString="Server=dbsrv;User ID=myDbUser;Password=somepass"word"
See this forum thread.
Update:
"
should work, but as it doesn't, have you tried some of the other string escape sequences for .NET? \"
and ""
?
Update 2:
Try single quotes for the connectionString:
connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'
Or:
connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'
Update 3:
From MSDN (SqlConnection.ConnectionString Property):
To include values that contain a semicolon, single-quote character, or double-quote character, the value must be enclosed in double quotation marks. If the value contains both a semicolon and a double-quote character, the value can be enclosed in single quotation marks.
So:
connectionString="Server=dbsrv;User ID=myDbUser;Password='somepass"word'"
The issue is not with web.config, but the format of the connection string. In a connection string, if you have a "
in a value (of the key-value pair), you need to enclose the value in '
. So, while Password=somepass"word
does not work, Password='somepass"word'
does.
Use the format()
function:
>>> format(14, '#010b')
'0b00001110'
The format()
function simply formats the input following the Format Specification mini language. The #
makes the format include the 0b
prefix, and the 010
size formats the output to fit in 10 characters width, with 0
padding; 2 characters for the 0b
prefix, the other 8 for the binary digits.
This is the most compact and direct option.
If you are putting the result in a larger string, use an formatted string literal (3.6+) or use str.format()
and put the second argument for the format()
function after the colon of the placeholder {:..}
:
>>> value = 14
>>> f'The produced output, in binary, is: {value:#010b}'
'The produced output, in binary, is: 0b00001110'
>>> 'The produced output, in binary, is: {:#010b}'.format(value)
'The produced output, in binary, is: 0b00001110'
As it happens, even for just formatting a single value (so without putting the result in a larger string), using a formatted string literal is faster than using format()
:
>>> import timeit
>>> timeit.timeit("f_(v, '#010b')", "v = 14; f_ = format") # use a local for performance
0.40298633499332936
>>> timeit.timeit("f'{v:#010b}'", "v = 14")
0.2850222919951193
But I'd use that only if performance in a tight loop matters, as format(...)
communicates the intent better.
If you did not want the 0b
prefix, simply drop the #
and adjust the length of the field:
>>> format(14, '08b')

The most simple and the correct way is to use Record type Record<string, string>
const myVar : Record<string, string> = {
key1: 'val1',
key2: 'val2',
}
It was very useful for me i have used in the following way to add user in active directory:
:: This file is used to automatically add list of user to activedirectory
:: First ask for username,pwd,dc details and run in loop
:: dsadd user cn=jai,cn=users,dc=mandrac,dc=com -pwd `1q`1q`1q`1q
@echo off
setlocal enableextensions enabledelayedexpansion
set /a "x = 1"
set /p lent="Enter how many Users you want to create : "
set /p Uname="Enter the user name which will be rotated with number ex:ram then ram1 ..etc : "
set /p DcName="Enter the DC name ex:mandrac : "
set /p Paswd="Enter the password you want to give to all the users : "
cls
:while1
if %x% leq %lent% (
dsadd user cn=%Uname%%x%,cn=users,dc=%DcName%,dc=com -pwd %Paswd%
echo User %Uname%%x% with DC %DcName% is created
set /a "x = x + 1"
goto :while1
)
endlocal
This was a pain, using netBeans IDE 7.2.
Add a resource folder to the src folder:
After the clean/build this structure is propogated into the Build folder:
To access the resources:
dlabel = new JLabel(new ImageIcon(getClass().getClassLoader().getResource("resources/images/logo.png")));
and:
if (common.readFile(getClass().getResourceAsStream("/resources/allwise.ini"), buf).equals("OK")) {
worked for me. Note that in one case there is a leading "/" and in the other there isn't. So the root of the path to the resources is the "classes" folder within the build folder.
Double click on the executable jar file in the dist folder. The path to the resources still works.
You can use n
for node's version management. There is a simple intro for n
.
$ npm install -g n
$ n 6.10.3
this is very easy to use.
then you can show your node version:
$ node -v
v6.10.3
For windows nvm is a well-received tool.
Ignore is exactly what the name implies.
It doesn't "throw away" something you don't need instead, it ignores the amount of characters you specify when you call it, up to the char you specify as a breakpoint.
It works with both input and output buffers.
Essentially, for std::cin
statements you use ignore before you do a getline
call, because when a user inputs something with std::cin
, they hit enter and a '\n'
char gets into the cin
buffer. Then if you use getline
, it gets the newline char instead of the string you want. So you do a std::cin.ignore(1000,'\n')
and that should clear the buffer up to the string that you want. (The 1000 is put there to skip over a specific amount of chars before the specified break point, in this case, the \n newline character.)
For today (year 2017) we have that awesome npm module: https://github.com/felixrieseberg/windows-build-tools which usually solves lots of troubles with building of native things for windows.
Try to fix the issue with:
Remove node_modules
npm install --global windows-build-tools
npm install
Try a different usb cable. My cable was bad. Charging was ok but did not attach the phone.
I found an excellent Chart.js
plugin that does exactly what you want:
https://github.com/emn178/Chart.PieceLabel.js
Let's look at this with the help of an example. Suppose we have a direct mapped cache and the write back policy is used. So we have a valid bit, a dirty bit, a tag and a data field in a cache line. Suppose we have an operation : write A ( where A is mapped to the first line of the cache).
What happens is that the data(A) from the processor gets written to the first line of the cache. The valid bit and tag bits are set. The dirty bit is set to 1.
Dirty bit simply indicates was the cache line ever written since it was last brought into the cache!
Now suppose another operation is performed : read E(where E is also mapped to the first cache line)
Since we have direct mapped cache, the first line can simply be replaced by the E block which will be brought from memory. But since the block last written into the line (block A) is not yet written into the memory(indicated by the dirty bit), so the cache controller will first issue a write back to the memory to transfer the block A to memory, then it will replace the line with block E by issuing a read operation to the memory. dirty bit is now set to 0.
So write back policy doesnot guarantee that the block will be the same in memory and its associated cache line. However whenever the line is about to be replaced, a write back is performed at first.
A write through policy is just the opposite. According to this, the memory will always have a up-to-date data. That is, if the cache block is written, the memory will also be written accordingly. (no use of dirty bits)
The simple solution given by Jonathan works with a modification to cheat Pandoc. Instead of direct Latex commands such as
\begin{center}
Text
\end{center}
you can define your own commands in the YAML header:
header-includes:
- \newcommand{\bcenter}{\begin{center}}
- \newcommand{\ecenter}{\end{center}}
And then you use:
\bcenter
Text and more
\ecenter
This works for me for centering a whole document with many code chunks and markdown commands in between.
If you know for sure that the element is present, you could try this to simulate the click - if .Click()
isn't working
driver.findElement(By.name("submit")).sendKeys(Keys.RETURN);
or
driver.findElement(By.name("submit")).sendKeys(Keys.ENTER);
Backticks are generally used to indicate an identifier
and as well be safe from accidentally using the Reserved Keywords.
For example:
Use `database`;
Here the backticks will help the server to understand that the database
is in fact the name of the database, not the database identifier.
Same can be done for the table names and field names. This is a very good habit if you wrap your database identifier with backticks.
Check this answer to understand more about backticks.
Now about Double quotes & Single Quotes (Michael has already mentioned that).
But, to define a value you have to use either single or double quotes. Lets see another example.
INSERT INTO `tablename` (`id, `title`) VALUES ( NULL, title1);
Here I have deliberately forgotten to wrap the title1
with quotes. Now the server will take the title1
as a column name (i.e. an identifier). So, to indicate that it's a value you have to use either double or single quotes.
INSERT INTO `tablename` (`id, `title`) VALUES ( NULL, 'title1');
Now, in combination with PHP, double quotes and single quotes make your query writing time much easier. Let's see a modified version of the query in your question.
$query = "INSERT INTO `table` (`id`, `col1`, `col2`) VALUES (NULL, '$val1', '$val2')";
Now, using double quotes in the PHP, you will make the variables $val1
, and $val2
to use their values thus creating a perfectly valid query. Like
$val1 = "my value 1";
$val2 = "my value 2";
$query = "INSERT INTO `table` (`id`, `col1`, `col2`) VALUES (NULL, '$val1', '$val2')";
will make
INSERT INTO `table` (`id`, `col1`, `col2`) VALUES (NULL, 'my value 1', 'my value 2')
No this will be a problem. PHP Variable Functions

This batch can run from anywhere. RD stands for Remove Directory but this can remove both folders and files which available to delete.
Just use public_path() it will find public folder and address it itself.

encodeURI() - the escape() function is for javascript escaping, not HTTP.
This might help
temp = ([[1,2,3,4,5,6,.....,7]])
After losing hours trying to find my error, the problem is your formula:
sigma = sum(y*(x-mean)**2)/n
This previous formula is wrong, the correct formula is the square root of this!;

Hope this helps
I don't think this DateTimePicker has been mentioned before:
A WPF DateTimePicker That Works Like the One in Winforms
That one is in VB and has some bugs. I converted it to C# and made a new version with bug fixes.
Note: I used the Calendar control in WPFToolkit so that I could use .NET 3.5 instead of .NET 4. If you are using .NET 4, just remove references to "wpftc" in the XAML.
To display the current system date in oracle-sql

I was also looking for a simple, robust, flexible and highly customizable bootstrap like react grid system to use in my projects.
The best I know of is react-pure-grid
https://www.npmjs.com/package/react-pure-grid
react-pure-grid
gives you the power to customize every aspect of your grid system, while at the same time it has built in defaults which probably suits any project
Usage
npm install react-pure-grid --save
-
import {Container, Row, Col} from 'react-pure-grid';
const App = () => (
<Container>
<Row>
<Col xs={6} md={4} lg={3}>Hello, world!</Col>
</Row>
<Row>
<Col xsOffset={5} xs={7}>Welcome!</Col>
</Row>
</Container>
);
As my first object is a native javascript object (used like a list of objects), push
didn't work in my escenario, but I resolved it by adding new key as following:
MyObjList['newKey'] = obj;
In addition to this, may be usefull to know how to delete same object inserted before:
delete MyObjList['newKey'][id];
Hope it helps someone as it helped me;

I found that jquery 1.11.1 does not do this reliably.
I used $('#estimate').attr('required', true)
and $('#estimate').removeAttr('required')
.
Removing required
was not reliable. It would sometimes leave the required
attribute without value. Since required
is a boolean attibute, its mere presence, without value, is seen by the browser as true
.
This bug was intermittent, and I got tired of messing with it. Switched to document.getElementById("estimate").required = true
and document.getElementById("estimate").required = false
.
Create a function that uses string replace
function convert(str)
{
str = str.replace(/&/g, "&");
str = str.replace(/>/g, ">");
str = str.replace(/</g, "<");
str = str.replace(/"/g, """);
str = str.replace(/'/g, "'");
return str;
}
Properties have the primary advantage of allowing you to change the way data on an object is accessed without breaking it's public interface. For example, if you need to add extra validation, or to change a stored field into a calculated you can do so easily if you initially exposed the field as a property. If you just exposed a field directly, then you would have to change the public interface of your class to add the new functionality. That change would break existing clients, requiring them to be recompiled before they could use the new version of your code.
If you write a class library designed for wide consumption (like the .NET Framework, which is used by millions of people), that can be a problem. However, if you are writing a class used internally inside a small code base (say <= 50 K lines), it's really not a big deal, because no one would be adversely affected by your changes. In that case it really just comes down to personal preference.

Say you have a class called MyFancyObject
like this one below:
class MyFancyObject
{
public int A { get;set;}
}
It lets you turn:
String ClassName = "MyFancyObject";
Into
MyFancyObject obj;
Using
obj = (MyFancyObject)Activator.CreateInstance("MyAssembly", ClassName))
and can then do stuff like:
obj.A = 100;
That's its purpose. It also has many other overloads such as providing a Type
instead of the class name in a string. Why you would have a problem like that is a different story. Here's some people who needed it:
The li
tag has a property called list-style-position
. This makes your bullets inside or outside the list. On default, it’s set to inside
. That makes your text wrap around it. If you set it to outside
, the text of your li
tags will be aligned.
The downside of that is that your bullets won't be aligned with the text outside the ul
. If you want to align it with the other text you can use a margin.
ul li {
/*
* We want the bullets outside of the list,
* so the text is aligned. Now the actual bullet
* is outside of the list’s container
*/
list-style-position: outside;
/*
* Because the bullet is outside of the list’s
* container, indent the list entirely
*/
margin-left: 1em;
}

Previously, I faced a similar problem, I needed to play .gif
file in your project. I had two choices:
using PictureBox from WinForms
using a third-party library, such as WPFAnimatedGif from codeplex.com.
Version with PictureBox
did not work for me, and the project could not use external libraries for it. So I made it for myself through Bitmap
with help ImageAnimator
. Because, standard BitmapImage
does not support playback of .gif
files.
Full example:
XAML
<Window x:Class="PlayGifHelp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Loaded="MainWindow_Loaded">
<Grid>
<Image x:Name="SampleImage" />
</Grid>
</Window>
Code behind
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
Bitmap _bitmap;
BitmapSource _source;
private BitmapSource GetSource()
{
if (_bitmap == null)
{
string path = Directory.GetCurrentDirectory();
// Check the path to the .gif file
_bitmap = new Bitmap(path + @"\anim.gif");
}
IntPtr handle = IntPtr.Zero;
handle = _bitmap.GetHbitmap();
return Imaging.CreateBitmapSourceFromHBitmap(handle, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
}
private void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
_source = GetSource();
SampleImage.Source = _source;
ImageAnimator.Animate(_bitmap, OnFrameChanged);
}
private void FrameUpdatedCallback()
{
ImageAnimator.UpdateFrames();
if (_source != null)
{
_source.Freeze();
}
_source = GetSource();
SampleImage.Source = _source;
InvalidateVisual();
}
private void OnFrameChanged(object sender, EventArgs e)
{
Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(FrameUpdatedCallback));
}
}
Bitmap
does not support URI directive, so I load .gif
file from the current directory.
I had the same issue with Visual Studio Community 2013, I fixed it downloading and installing the latest update of Office Developer Tools for Visual Studio 2013. Now I am able to see the whole Microsoft.Office.Interop.* list when I go to
Add References > Assemblies > Extensions
you can download it from here:

I have not used Recyclerview but I did it on ListView. Sample code in Recyclerview:
setOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
rowPos = mLayoutManager.findFirstVisibleItemPosition();
It is the listener when user is scrolling. The performance overhead is not significant. And the first visible position is accurate this way.
This parameter is just about whether you are going to use complex html into the tooltip. Set it to true
and then hit the html into the title
attribute of the tag.
See this fiddle here - I've set the html attribute to true through the data-html="true"
in the <a>
tag and then just added in the html ad hoc as an example.
Try this code:
Dim lastrow As Long
lastrow = Cells(Rows.Count, 2).End(xlUp).Row
Range("A3:D" & lastrow).Sort key1:=Range("B3:B" & lastrow), _
order1:=xlAscending, Header:=xlNo
You can use it without doing anything special. If you have a local image called blah
you can do FROM blah
. If you do FROM blah
in your Dockerfile, but don't have a local image called blah
, then Docker will try to pull it from the registry.
In other words, if a Dockerfile does FROM ubuntu
, but you have a local image called ubuntu
different from the official one, your image will override it.

I know this thread has been idle for a while, but I just wanted to add my two cents to supplement jariq's comment...
Per manual, you don't necessary want to use -password
option.
Let's say mykey.key
has a password and your want to protect iphone-dev.p12
with another password, this is what you'd use:
pkcs12 -export -inkey mykey.key -in developer_identity.pem -out iphone_dev.p12 -passin pass:password_for_mykey -passout pass:password_for_iphone_dev
Have fun scripting!!
I have also faced the similar problem with the following details Java 1.8.0_121, Spark spark-1.6.1-bin-hadoop2.6, Windows 10 and Eclipse Oxygen.When I ran my WordCount.java in Eclipse using HADOOP_HOME as a system variable as mentioned in the previous post, it did not work, what worked for me is -
System.setProperty("hadoop.home.dir", "PATH/TO/THE/DIR");
PATH/TO/THE/DIR/bin=winutils.exe whether you run within Eclipse as a Java application or by spark-submit from cmd using
spark-submit --class groupid.artifactid.classname --master local[2] /path to the jar file created using maven /path to a demo test file /path to output directory command
Example: Go to the bin location of Spark/home/location/bin and execute the spark-submit as mentioned,
D:\BigData\spark-2.3.0-bin-hadoop2.7\bin>spark-submit --class com.bigdata.abdus.sparkdemo.WordCount --master local[1] D:\BigData\spark-quickstart\target\spark-quickstart-0.0.1-SNAPSHOT.jar D:\BigData\spark-quickstart\wordcount.txt

-10.days.ago
# Available in Rails 4
DateTime.now.days_ago(-10)
Just list out all options I know:
[1] Time.now + 10.days
[2] 10.days.from_now
[3] -10.days.ago
[4] DateTime.now.days_ago(-10)
[5] Date.today + 10
So now, what is the difference between them if we care about the timezone:
[1, 4]
With system timezone[2, 3]
With config timezone of your Rails app[5]
Date only no time included in resultFYI: it looks like you might have an infinite loop in your example...
if cnt > 0 and len(aStr) > 1:
while cnt > 0:
aStr = aStr[1:]+aStr[0]
cnt += 1
cnt
is greater than 0cnt
is greater than 0cnt
by 1The net result is that cnt
will always be greater than 0 and the loop will never exit.
You can evaluate based on severity type. Note to use this you must be subscribed to OnInfoMessage
conn.InfoMessage += OnInfoMessage;
conn.FireInfoMessageEventOnUserErrors = true;
Then your OnInfoMessage would contain:
foreach(SqlError err in e.Errors) {
//Informational Errors
if (Between(Convert.ToInt16(err.Class), 0, 10, true)) {
logger.Info(err.Message);
//Errors users can correct.
} else if (Between(Convert.ToInt16(err.Class), 11, 16, true)) {
logger.Error(err.Message);
//Errors SysAdmin can correct.
} else if (Between(Convert.ToInt16(err.Class), 17, 19, true)) {
logger.Error(err.Message);
//Fatal Errors 20+
} else {
logger.Fatal(err.Message);
}}
This way you can evaluate on severity rather than on error number and be more effective. You can find more information on severity here.
private static bool Between( int num, int lower, int upper, bool inclusive = false )
{
return inclusive
? lower <= num && num <= upper
: lower < num && num < upper;
}
The answer about "short-circuiting" is potentially misleading, but has some truth (see below). In the R/S language, &&
and ||
only evaluate the first element in the first argument. All other elements in a vector or list are ignored regardless of the first ones value. Those operators are designed to work with the if (cond) {} else{}
construction and to direct program control rather than construct new vectors.. The &
and the |
operators are designed to work on vectors, so they will be applied "in parallel", so to speak, along the length of the longest argument. Both vectors need to be evaluated before the comparisons are made. If the vectors are not the same length, then recycling of the shorter argument is performed.
When the arguments to &&
or ||
are evaluated, there is "short-circuiting" in that if any of the values in succession from left to right are determinative, then evaluations cease and the final value is returned.
> if( print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(FALSE && print(1) ) {print(2)} else {print(3)} # `print(1)` not evaluated
[1] 3
> if(TRUE && print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(TRUE && !print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 3
> if(FALSE && !print(1) ) {print(2)} else {print(3)}
[1] 3
The advantage of short-circuiting will only appear when the arguments take a long time to evaluate. That will typically occur when the arguments are functions that either process larger objects or have mathematical operations that are more complex.
Your regex seems a bit too complex in my opinion. Also, remember that the dot is a special character meaning "any character". The following regex should work (note the escaped dots):

'2 days 5 mins 8 secs 3 msecs'
or round to minutes, omit below minutes:
>>> td = timedelta(days=1, hours=2, minutes=5, seconds=8, microseconds=3549)
>>> strfdelta_round(td, 'minute')
'1 days 2 hours 5 mins'
You can fix the rounding by subtracting 0.5 for toFixed, e.g.
(f - 0.005).toFixed(2)
From official readxl
(tidyverse) documentation (changing first line):
path <- "data/datasets.xlsx"
path %>%
excel_sheets() %>%
set_names() %>%
map(read_excel, path = path)
By the way, you can use next code in you event handler:
switch(e.EventType)
{
case SerialData.Chars:
{
// means you receives something
break;
}
case SerialData.Eof:
{
// means receiving ended
break;
}
}
This following syntax works for me.
UPDATE
(SELECT A.utl_id,
b.utl1_id
FROM trb_pi_joint A
JOIN trb_tpr B
ON A.tp_id=B.tp_id Where A.pij_type=2 and a.utl_id is null
)
SET utl_id=utl1_id;
I used title and it worked!
The title attribute gives the title of the link. With one exception, it is purely advisory. The value is text. The exception is for style sheet links, where the title attribute defines alternative style sheet sets.

Issue no 2.
Your local server has two database server and those database server conflict. this conflict like this mysql server & xampp or lampp or wamp server. Please one of the database like mysql server because xampp or lampp server automatically install mysql server on this machine
it's also a good thing to make sure you have the right import
I had an issue like that and I found out that the bean was using
javax.faces.view.ViewScoped;
^
instead of
javax.faces.bean.ViewScoped;
^
This can be the message you receive even when custom errors is turned off in web.config file. It can mean you have run out of free space on the drive that hosts the application. Clean your log files if you have no other space to gain on the drive.

In Java i usually need to return int and use this form:
int count = ((Long)getSession().createQuery("select count(*) from Book").uniqueResult()).intValue();
parseInt() or parseFloat() are functions in JavaScript which can help you convert the values into integers or floats respectively.
parseInt(string, radix);
parseFloat(string);
var x = prompt("Enter a Value", "0");
var y = prompt("Enter a Value", "0");
var num1 = parseInt(x);
var num2 = parseInt(y);
After this you can perform which ever calculations you want on them.
Use the gca
("get current axes") helper function:
ax = plt.gca()
Example:
import matplotlib.pyplot as plt
import matplotlib.finance
quotes = [(1, 5, 6, 7, 4), (2, 6, 9, 9, 6), (3, 9, 8, 10, 8), (4, 8, 8, 9, 8), (5, 8, 11, 13, 7)]
ax = plt.gca()
h = matplotlib.finance.candlestick(ax, quotes)
plt.show()
The below also happens to answer the Original Poster's question without, the "ugly" conditional code that some commenters have mentioned.
CONTIGUOUS NON-PRINTING Ruby Code
This will work in any mixed language Rails View file, e.g, *.html.erb, *.js.erb, *.rhtml
, etc.
This should also work with STD OUT/printing code, e.g. <%#= f.label :title %>
DETAILS:
Rather than use rails brackets on each line and commenting in front of each starting bracket as we usually do like this:
<%# if flash[:myErrors] %>
<%# if flash[:myErrors].any? %>
<%# if @post.id.nil? %>
<%# if @myPost!=-1 %>
<%# @post = @myPost %>
<%# else %>
<%# @post = Post.new %>
<%# end %>
<%# end %>
<%# end %>
<%# end %>
YOU CAN INSTEAD add only one comment (hashmark/poundsign) to the first open Rails bracket if you write your code as one large block... LIKE THIS:
<%#
if flash[:myErrors] then
if flash[:myErrors].any? then
if @post.id.nil? then
if @myPost!=-1 then
@post = @myPost
else
@post = Post.new
end
end
end
end
%>
For SQL Server 2008, I would imagine the procedure is similar...?
You can do something like this:
var radios = document.getElementsByName('genderS');_x000D_
_x000D_
for (var i = 0, length = radios.length; i < length; i++) {_x000D_
if (radios[i].checked) {_x000D_
// do whatever you want with the checked radio_x000D_
alert(radios[i].value);_x000D_
_x000D_
// only one radio can be logically checked, don't check the rest_x000D_
break;_x000D_
}_x000D_
}
_x000D_
<label for="gender">Gender: </label>_x000D_
<input type="radio" name="genderS" value="1" checked="checked">Male</input>_x000D_
<input type="radio" name="genderS" value="0">Female</input>
_x000D_
Edit: Thanks HATCHA and jpsetung for your edit suggestions.
In addition to @ImportanceOfBeingErnest's post, I use the following line to add a legend at an absolute position in a plot.
plt.legend(bbox_to_anchor=(1.0,1.0),\
bbox_transform=plt.gcf().transFigure)
For unknown reasons, bbox_transform=fig.transFigure
does not work with me.
Try this variation:
$(".tr_clone_add").live('click', CloneRow);
function CloneRow()
{
$(this).closest('.tr_clone').clone().insertAfter(".tr_clone:last");
}
You should use the equals
method since this is implemented to perform the comparison you want. toString()
itself uses an iterator just like equals
but it is a more inefficient approach. Additionally, as @Teepeemm pointed out, toString
is affected by order of elements (basically iterator return order) hence is not guaranteed to provide the same output for 2 different maps (especially if we compare two different maps).
Note/Warning: Your question and my answer assume that classes implementing the map interface respect expected toString
and equals
behavior. The default java classes do so, but a custom map class needs to be examined to verify expected behavior.
See: http://docs.oracle.com/javase/7/docs/api/java/util/Map.html
boolean equals(Object o)
Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.
Additionally, java itself takes care of iterating through all elements and making the comparison so you don't have to. Have a look at the implementation of AbstractMap
which is used by classes such as HashMap
:
// Comparison and hashing
/**
* Compares the specified object with this map for equality. Returns
* <tt>true</tt> if the given object is also a map and the two maps
* represent the same mappings. More formally, two maps <tt>m1</tt> and
* <tt>m2</tt> represent the same mappings if
* <tt>m1.entrySet().equals(m2.entrySet())</tt>. This ensures that the
* <tt>equals</tt> method works properly across different implementations
* of the <tt>Map</tt> interface.
*
* <p>This implementation first checks if the specified object is this map;
* if so it returns <tt>true</tt>. Then, it checks if the specified
* object is a map whose size is identical to the size of this map; if
* not, it returns <tt>false</tt>. If so, it iterates over this map's
* <tt>entrySet</tt> collection, and checks that the specified map
* contains each mapping that this map contains. If the specified map
* fails to contain such a mapping, <tt>false</tt> is returned. If the
* iteration completes, <tt>true</tt> is returned.
*
* @param o object to be compared for equality with this map
* @return <tt>true</tt> if the specified object is equal to this map
*/
public boolean equals(Object o) {
if (o == this)
return true;
if (!(o instanceof Map))
return false;
Map<K,V> m = (Map<K,V>) o;
if (m.size() != size())
return false;
try {
Iterator<Entry<K,V>> i = entrySet().iterator();
while (i.hasNext()) {
Entry<K,V> e = i.next();
K key = e.getKey();
V value = e.getValue();
if (value == null) {
if (!(m.get(key)==null && m.containsKey(key)))
return false;
} else {
if (!value.equals(m.get(key)))
return false;
}
}
} catch (ClassCastException unused) {
return false;
} catch (NullPointerException unused) {
return false;
}
return true;
}
toString
fails miserably when comparing a TreeMap
and HashMap
though equals
does compare contents correctly.
Code:
public static void main(String args[]) {
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("2", "whatever2");
map.put("1", "whatever1");
TreeMap<String, Object> map2 = new TreeMap<String, Object>();
map2.put("2", "whatever2");
map2.put("1", "whatever1");
System.out.println("Are maps equal (using equals):" + map.equals(map2));
System.out.println("Are maps equal (using toString().equals()):"
+ map.toString().equals(map2.toString()));
System.out.println("Map1:"+map.toString());
System.out.println("Map2:"+map2.toString());
}
Output:
Are maps equal (using equals):true
Are maps equal (using toString().equals()):false
Map1:{2=whatever2, 1=whatever1}
Map2:{1=whatever1, 2=whatever2}
You must define states not equal to null..
@if (ViewBag.States!= null)
{
@foreach (KeyValuePair<int, string> de in ViewBag.States)
{
value="@de.Key">@de.Value
}
}
I know it's an old question, but I believe still valid even in 2018.
There is an option to Take a bug report hidden in Developer options in every android device.
NOTE: This would dump whole system log
How to enable developer options? see: https://developer.android.com/studio/debug/dev-options
What works for me:
how to read this? open bugreport-1960-01-01-hh-mm-ss.txt
you probably want to look for something like this:
------ SYSTEM LOG (logcat -v threadtime -v printable -d *:v) ------
--------- beginning of crash
06-13 14:37:36.542 19294 19294 E AndroidRuntime: FATAL EXCEPTION: main
or:
------ SYSTEM LOG (logcat -v threadtime -v printable -d *:v) ------
--------- beginning of main
Here is the same solution (with some extra bonus code) in just one XML file:
<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/edittext_rounded_corners.xml -->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:state_focused="true">
<shape>
<solid android:color="#FF8000"/>
<stroke
android:width="2.3dp"
android:color="#FF8000" />
<corners
android:radius="15dp" />
</shape>
</item>
<item android:state_pressed="true" android:state_focused="false">
<shape>
<solid android:color="#FF8000"/>
<stroke
android:width="2.3dp"
android:color="#FF8000" />
<corners
android:radius="15dp" />
</shape>
</item>
<item android:state_pressed="false" android:state_focused="true">
<shape>
<solid android:color="#FFFFFF"/>
<stroke
android:width="2.3dp"
android:color="#FF8000" />
<corners
android:radius="15dp" />
</shape>
</item>
<item android:state_pressed="false" android:state_focused="false">
<shape>
<gradient
android:startColor="#F2F2F2"
android:centerColor="#FFFFFF"
android:endColor="#FFFFFF"
android:angle="270"
/>
<stroke
android:width="0.7dp"
android:color="#BDBDBD" />
<corners
android:radius="15dp" />
</shape>
</item>
<item android:state_enabled="true">
<shape>
<padding
android:left="4dp"
android:top="4dp"
android:right="4dp"
android:bottom="4dp"
/>
</shape>
</item>
</selector>
You then just set the background attribute to edittext_rounded_corners.xml file:
<EditText android:id="@+id/editText_name"
android:background="@drawable/edittext_rounded_corners"/>
Try the following.
$d = [datetime](Get-ItemProperty -Path $source -Name LastWriteTime).lastwritetime
This is part of the item property weirdness. When you run Get-ItemProperty it does not return the value but instead the property. You have to use one more level of indirection to get to the value.
In their latest release there's a directive called md-icon
<md-icon icon="img/icons/ic_refresh_24px.svg"></md-icon>
Here's a real world example of why Closures kick ass... This is straight out of my Javascript code. Let me illustrate.
Function.prototype.delay = function(ms /*[, arg...]*/) {
var fn = this,
args = Array.prototype.slice.call(arguments, 1);
return window.setTimeout(function() {
return fn.apply(fn, args);
}, ms);
};
And here's how you would use it:
var startPlayback = function(track) {
Player.play(track);
};
startPlayback(someTrack);
Now imagine you want the playback to start delayed, like for example 5 seconds later after this code snippet runs. Well that's easy with delay
and it's closure:
startPlayback.delay(5000, someTrack);
// Keep going, do other things
When you call delay
with 5000
ms, the first snippet runs, and stores the passed in arguments in it's closure. Then 5 seconds later, when the setTimeout
callback happens, the closure still maintains those variables, so it can call the original function with the original parameters.
This is a type of currying, or function decoration.
Without closures, you would have to somehow maintain those variables state outside the function, thus littering code outside the function with something that logically belongs inside it. Using closures can greatly improve the quality and readability of your code.
you can get the key value pair as
<pre>
function test(){
var data=[{'com':'something'},{'com':'some other thing'}];
$.each(data, function(key,value) {
alert(key);
alert(value.com);
});
}
</pre>
Since no-one has yet wrote a function to do this with two integers, here's one way:
private long CalculatePower(int number, int powerOf)
{
for (int i = powerOf; i > 1; i--)
number *= number;
return number;
}
CalculatePower(5, 3); // 125
CalculatePower(8, 4); // 4096
CalculatePower(6, 2); // 36
Alternatively in VB.NET:
Private Function CalculatePower(number As Integer, powerOf As Integer) As Long
For i As Integer = powerOf To 2 Step -1
number *= number
Next
Return number
End Function
CalculatePower(5, 3) ' 125
CalculatePower(8, 4) ' 4096
CalculatePower(6, 2) ' 36
I actual ran into the same requirement. I simply used CSS override like this
.navbar .btn-toolbar { margin-top: 0; margin-bottom: 0 }
Use unless
:
unless @players.include?(p.name) do
...
end
input(prompt)
is basically equivalent to
def input(prompt):
print(prompt, end='', file=sys.stderr)
return sys.stdin.readline()
You can read directly from sys.stdin
if you like.
lines = sys.stdin.readlines()
lines = [line for line in sys.stdin]
five_lines = list(itertools.islice(sys.stdin, 5))
The first two require that the input end somehow, either by reaching the end of a file or by the user typing Control-D (or Control-Z in Windows) to signal the end. The last one will return after five lines have been read, whether from a file or from the terminal/keyboard.
This works on keyup and paste, it colors the text red when you are almost up to the limit, truncates it when you go over and alerts you to edit your text, which you can do.
var t2= /* textarea reference*/
t2.onkeyup= t2.onpaste= function(e){
e= e || window.event;
var who= e.target || e.srcElement;
if(who){
var val= who.value, L= val.length;
if(L> 175){
who.style.color= 'red';
}
else who.style.color= ''
if(L> 180){
who.value= who.value.substring(0, 175);
alert('Your message is too long, please shorten it to 180 characters or less');
who.style.color= '';
}
}
}
Swift 5: Here is a cool and easy extension to remove elements in an array, without filtering :
extension Array where Element: Equatable {
// Remove first collection element that is equal to the given `object`:
mutating func remove(object: Element) {
guard let index = firstIndex(of: object) else {return}
remove(at: index)
}
}
Usage :
var myArray = ["cat", "barbecue", "pancake", "frog"]
let objectToRemove = "cat"
myArray.remove(object: objectToRemove) // ["barbecue", "pancake", "frog"]
Also works with other types, such as Int
since Element
is a generic type:
var myArray = [4, 8, 17, 6, 2]
let objectToRemove = 17
myArray.remove(object: objectToRemove) // [4, 8, 6, 2]

I know this is an old question, but our solution is much simpler than what I see here. We use it for WCF calls with VS2010 and up. The string url can come from app settings or another source. In my case it is a drop down list where the user picks the server. TheService was configured through VS add service reference.
private void CallTheService( string url )
{
TheService.TheServiceClient client = new TheService.TheServiceClient();
client.Endpoint.Address = new System.ServiceModel.EndpointAddress(url);
var results = client.AMethodFromTheService();
}
You can create your own lock with GET_LOCK(lockName,timeOut)
If you do a GET_LOCK(lockName, 0)
with a 0 time out before you lock the tables and then follow that with a RELEASE_LOCK(lockName)
then all other threads performing a GET_LOCK()
will get a value of 0 which will tell them that the lock is being held by another thread.
However this won't work if you don't have all threads calling GET_LOCK()
before locking tables. The documentation for locking tables is here
Hope that helps!
items[node.ind] = items[node.ind]._replace(v=node.v)
(Note: Don't be discouraged to use this solution because of the leading underscore in the function _replace. Specifically for namedtuple some functions have leading underscore which is not for indicating they are meant to be "private")
I faced a problem upgrading pip from version 9.0.1 to 9.0.3 The upgrade failed middle way(after uninstalling version 9.0.1 and without installing version 9.0.3). This usually creates a broken pip file. Broken pip can be solved by the command-->
easy_install pip
Which usually installs the latest version of pip, and solves the issue. In order to confirm, type
pip --version
Hope this was helpfull...
Just to add to the list of options. You can also grab the object from the database, and use an auto mapping tool like Auto Mapper to update the parts of the record you want to change..
How about this:
ALTER TABLE dbo.testRequest
ADD CONSTRAINT PK_TestRequest

I was looking for fast way to do the subject, so I made some experiments with suggested ways. And I was surprised by results, so I want to share it with you.
Experiments were done using pythonbenchmark tool and with
a = range(1,50000) # Source list
b = range(1,15000) # Items to remove
Results:
def comprehension(a, b):
return [x for x in a if x not in b]
5 tries, average time 12.8 sec
def filter_function(a, b):
return filter(lambda x: x not in b, a)
5 tries, average time 12.6 sec
def modification(a,b):
for x in b:
try:
a.remove(x)
except ValueError:
pass
return a
5 tries, average time 0.27 sec
def set_approach(a,b):
return list(set(a)-set(b))
5 tries, average time 0.0057 sec
Also I made another measurement with bigger inputs size for the last two functions
a = range(1,500000)
b = range(1,100000)
And the results:
For modification (remove method) - average time is 252 seconds For set approach - average time is 0.75 seconds
So you can see that approach with sets is significantly faster than others. Yes, it doesn't keep similar items, but if you don't need it - it's for you. And there is almost no difference between list comprehension and using filter function. Using 'remove' is ~50 times faster, but it modifies source list. And the best choice is using sets - it's more than 1000 times faster than list comprehension!
Identify "project navigator"
or "package explorer"
view.
Right click on your project, select Build Path --> Configure build Path
.
In the emerging window, you will find four tabs, select "Libraries"
.There, under "Web app libraries"
(expand it), you will see the libraries added to the project's classpath. Check if all of them are available. If one or more are not (they'll have "missing" beside their name and a red mark on their icon), check if you need them (perhaps you don't); if you don't need them, remove it, if you need them, exit this window, look out for the missing jar and IMPORT it into your project.
I forced to use a proxy and also forced to add proxy setting on gradle.properties as these:
systemProp.http.proxyHost=127.0.0.1
systemProp.http.proxyPort=1080
systemProp.https.proxyHost=127.0.0.1
systemProp.https.proxyPort=1080
And also forced to close and open studio64.exe
as administrator .
Now its all seems greate

App.Config is an XML file that is used as a configuration file for your application. In other words, you store inside it any setting that you may want to change without having to change code (and recompiling). It is often used to store connection strings.
See this MSDN article on how to do that.
Quick summary, you can do either:
Include the JavaFX modules via --module-path
and --add-modules
like in José's answer.
OR
Once you have JavaFX libraries added to your project (either manually or via maven/gradle import), add the module-info.java
file similar to the one specified in this answer. (Note that this solution makes your app modular, so if you use other libraries, you will also need to add statements to require their modules inside the module-info.java
file).
This answer is a supplement to Jose's answer.
The situation is this:

Exception running application org.jewelsea.demo.javafx.springboot.Main
OK, now you are kind of stuck and have no clue what is going on.
What has actually happened is this:
So it seems everything should be OK. BUT, when you run your application, the code in the JavaFX modules is failing when trying to use reflection to instantiate instances of your application class (when you invoke launch) and your FXML controller classes (when you load FXML). Without some help, this use of reflection can fail in some cases, generating the obscure IllegalAccessError
. This is due to a Java module system security feature which does not allow code from other modules to use reflection on your classes unless you explicitly allow it (and the JavaFX application launcher and FXMLLoader both require reflection in their current implementation in order for them to function correctly).
This is where some of the other answers to this question, which reference module-info.java
, come into the picture.
So let's take a crash course in Java modules:
The key part is this:
4.9. Opens
If we need to allow reflection of private types, but we don't want all of our code exposed, we can use the opens directive to expose specific packages.
But remember, this will open the package up to the entire world, so make sure that is what you want:
module my.module { opens com.my.package; }
So, perhaps you don't want to open your package to the entire world, then you can do:
4.10. Opens … To
Okay, so reflection is great sometimes, but we still want as much security as we can get from encapsulation. We can selectively open our packages to a pre-approved list of modules, in this case, using the opens…to directive:
module my.module { opens com.my.package to moduleOne, moduleTwo, etc.; }
So, you end up creating a src/main/java/module-info.java class which looks like this:
module org.jewelsea.demo.javafx.springboot {
requires javafx.fxml;
requires javafx.controls;
requires javafx.graphics;
opens org.jewelsea.demo.javafx.springboot to javafx.graphics,javafx.fxml;
}
Where, org.jewelsea.demo.javafx.springboot
is the name of the package which contains the JavaFX Application class and JavaFX Controller classes (replace this with the appropriate package name for your application). This tells the Java runtime that it is OK for classes in the javafx.graphics
and javafx.fxml
to invoke reflection on the classes in your org.jewelsea.demo.javafx.springboot
package. Once this is done, and the application is compiled and re-run things will work fine and the IllegalAccessError
generated by JavaFX's use of reflection will no longer occur.
But what if you don't want to create a module-info.java file
If instead of using the the Run button in the top toolbar of IDE to run your application class directly, you instead:
javafx.run
.Run Maven Build
or Debug...
.Then the app will run without the module-info.java
file. I guess this is because the maven plugin is smart enough to dynamically include some kind of settings which allows the app to be reflected on by the JavaFX classes even without a module-info.java
file, though I don't know how this is accomplished.
To get that setting transferred to the Run button in the top toolbar, right-click on the javafx.run
Maven target and choose the option to Create Run/Debug Configuration
for the target. Then you can just choose Run from the top toolbar to execute the Maven target.
You can also get SIGBUS when a code page cannot be paged in for some reason.

It might be helpful to take a look at .git/config
inside your repo, it will list all remotes and also the default remote for each branch
eg.
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = [email protected]:fii/web2016.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
[branch "bugfix/#8302"]
remote = origin
merge = "refs/heads/bugfix/#8302"
[branch "feature/#8331"]
remote = origin
merge = "refs/heads/feature/#8331"
[remote "scm"]
url = https://scm.xxx.be/git/web2016bs.git
fetch = +refs/heads/*:refs/remotes/scm/*
you can make manual changes in this file to remove an unwanted remote, or update the default remotes for the different branches you have

That looks like the GitLab issue 5769.
In GitLab, since the repositories always end in
.git
, I must specify.git
at the end of the repository name to make it work, for example:import "example.org/myuser/mygorepo.git"
And:
$ go get example.org/myuser/mygorepo.git
Looks like GitHub solves this by appending
".git"
.
It is supposed to be resolved in “Added support for Go's repository retrieval. #5958”, provided the right meta tags are in place.
Although there is still an issue for Go itself: “cmd/go
: go get cannot discover meta tag in HTML5 documents”.
I had this error and all the configurations mentioned above were correct however I was still getting "The client and service bindings may be mismatched" error.
What resolved my error, was matching the messageEncoding attribute values in the following node of service and client config files. They were different in mine, service was Text and client Mtom. Changing service to Mtom to match client's, resolved the issue.
<configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_IMySevice" ... messageEncoding="Mtom">
...
</binding>
</basicHttpBinding>
</bindings>
</system.serviceModel>
</configuration>
I arranged a little. This works great.
@SuppressLint("SimpleDateFormat") SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd MM yyyy");

String timeofday = android.text.format.DateFormat.format("HH:mm:ss", new Date().getTime()).toString();
@SuppressLint("SimpleDateFormat") SimpleDateFormat dateFormat = new SimpleDateFormat("dd MM yyyy hh:mm:ss");
try {
Date date1 = dateFormat.parse(06 09 2018 + " " + 10:12:56);

long different = endDate.getTime() - startDate.getTime();
long secondsInMilli = 1000;
long minutesInMilli = secondsInMilli * 60;
long hoursInMilli = minutesInMilli * 60;
long daysInMilli = hoursInMilli * 24;
long elapsedDays = different / daysInMilli;
different = different % daysInMilli;
long elapsedHours = different / hoursInMilli;
different = different % hoursInMilli;
long elapsedMinutes = different / minutesInMilli;
different = different % minutesInMilli;
long elapsedSeconds = different / secondsInMilli;
Toast.makeText(context, elapsedDays + " " + elapsedHours + " " + elapsedMinutes + " " + elapsedSeconds, Toast.LENGTH_SHORT).show();
}
Here's a Swift version:
func durationsBySecond(seconds s: Int) -> (days:Int,hours:Int,minutes:Int,seconds:Int) {
return (s / (24 * 3600),(s % (24 * 3600)) / 3600, s % 3600 / 60, s % 60)
}
Can be used like this:
let (d,h,m,s) = durationsBySecond(seconds: duration)
println("time left: \(d) days \(h) hours \(m) minutes \(s) seconds")
you can use the following
private async Task<List<string>> GetItems()
{
return await Task.FromResult(new List<string>
{
"item1", "item2", "item3"
});
}
The answer I have finally found is that the SMTP service on the server is not using the same certificate as https.
The diagnostic steps I had read here make the assumption they use the same certificate and every time I've tried this in the past they have done and the diagnostic steps are exactly what I've done to solve the problem several times.
In this case those steps didn't work because the certificates in use were different, and the possibility of this is something I had never come across.
The solution is either to export the actual certificate from the server and then install it as a trusted certificate on my machine, or to get a different valid/trusted certificate for the SMTP service on the server. That is currently with our IT department who administer the servers to decide which they want to do.
You can use window.location
window.location="/newpage.php";
Or you can just make the form that the search button is in have a action of the page you want.
You need to create a query (in Visual Studio, right-click on the DB connection -> New Query) and execute the following SQL:
ALTER TABLE tblAlpha
ADD CONSTRAINT MyConstraint FOREIGN KEY (FK_id) REFERENCES
tblGamma(GammaID)
ON UPDATE CASCADE
To verify that your foreign key was created, execute the following SQL:

You need to transform the object you are getting back into an array in the format that jQueryUI expects.
You can use $.map
to transform the dealers
object into that array.
$('#dealerName').autocomplete({
source: function (request, response) {
$.getJSON("/example/location/example.json?term=" + request.term, function (data) {
response($.map(data.dealers, function (value, key) {
return {
label: value,
value: key
};
}));
});
},
minLength: 2,
delay: 100
});
Note that when you select an item, the "key" will be placed in the text box. You can change this by tweaking the label
and value
properties that $.map
's callback function return.
Alternatively, if you have access to the server-side code that is generating the JSON, you could change the way the data is returned. As long as the data:
label
property, a value
property, or both, orIn other words, if you can format the data like this:
[{ value: "1463", label: "dealer 5"}, { value: "269", label: "dealer 6" }]
or this:
["dealer 5", "dealer 6"]
Then your JavaScript becomes much simpler:
$('#dealerName').autocomplete({
source: "/example/location/example.json"
});

I faced the same exception while trying to test my web-services deployed to WSO2 ESB.
WSO2 generated both wsdl and wsdl2. I tried to pass a wsdl2 URL and got the above exception. Quick googling showed me, that one of differences between wsdl1.1 and wsdl2.0 is replacing 'definitions' element with 'description'. Also, I found out, that SoapUI does not support wsdl2.
Therefore, for me the solution was to use wsdl1 url instead of wsdl2.
To create a Windows Service from an executable, you can use sc.exe
:
sc.exe create <new_service_name> binPath= "<path_to_the_service_executable>"
You must have quotation marks around the actual exe
path, and a space after the binPath=
.
More information on the sc
command can be found in Microsoft KB251192.
Note that it will not work for just any executable: the executable must be a Windows Service (i.e. implement ServiceMain). When registering a non-service executable as a service, you'll get the following error upon trying to start the service:
Error 1053: The service did not respond to the start or control request in a timely fashion.
There are tools that can create a Windows Service from arbitrary, non-service executables, see the other answers for examples of such tools.
As already answered, the C standards have no way to directly write binary numbers. There are compiler extensions, however, and apparently C++14 includes the 0b
prefix for binary. (Note that this answer was originally posted in 2010.)
One popular workaround is to include a header file with helper macros. One easy option is also to generate a file that includes macro definitions for all 8-bit patterns, e.g.:
#define B00000000 0
#define B00000001 1
#define B00000010 2
…
This results in only 256 #define
s, and if larger than 8-bit binary constants are needed, these definitions can be combined with shifts and ORs, possibly with helper macros (e.g., BIN16(B00000001,B00001010)
). (Having individual macros for every 16-bit, let alone 32-bit, value is not plausible.)
Of course the downside is that this syntax requires writing all the leading zeroes, but this may also make it clearer for uses like setting bit flags and contents of hardware registers. For a function-like macro resulting in a syntax without this property, see bithacks.h
linked above.
You will then have access to network via wifi card.

I hope you are trying to extract :
"Performance"
"Maintenance"
"System Stability"
Here is the way - Step 1/3: Open Search->Find->Replace Tab , select Regular Expression Radio button. Enter in Find what : (\"[a-zA-Z0-9\s]+\") and in Replace with : \n\1 and click Replace All buttton.
Step 2/3: After first step your keywords will be in next lines.(as shown in next image). Now go to Mark tab and enter the same regex expression in Find what: Field. Put check mark on Bookmark Line. Then Click Mark All.
Step 3/3 : Goto Search -> Bookmarks -> Remove unmarked lines.
window.opener.location.href ='workItem.adm?wiId='+${param.wiId};
It will go to the required path and you won't get any resend prompt.
This should work because it uses List as you don't know how many lines will be there in the file and also they may change later.
BufferedReader in = new BufferedReader(new FileReader("path/of/text"));
String str=null;
ArrayList<String> lines = new ArrayList<String>();
while((str = in.readLine()) != null){
lines.add(str);
}
String[] linesArray = lines.toArray(new String[lines.size()]);
Use
cut -b COLUMN_N_BEGINS-COLUMN_N_UNTIL INPUT.TXT > OUTPUT.TXT
-f
doesn't work if you have "tabs" in the text file.
I had this problem too, but I solved it in a much simpler way...
I was using the class "ckeditor" in my jQuery script as the selector for which textareas I wanted use for CKEditor. The default ckeditor JS script also uses this class to identify which textareas to use for CKEditor.
This meant there is a conflict between my jQuery script and the default ckeditor script.
I simply changed the class of the textarea and my jQuery script to 'do_ckeditor'(you could use anything except "ckeditor") and it worked.

Your variable size
is declared as: float size;
You can't use a floating point variable as the size of an array - it needs to be an integer value.
You could cast it to convert to an integer:
float *temp = new float[(int)size];
Your other problem is likely because you're writing outside of the bounds of the array:
float *temp = new float[size];
//Getting input from the user
for (int x = 1; x <= size; x++){
cout << "Enter temperature " << x << ": ";
// cin >> temp[x];
// This should be:
cin >> temp[x - 1];
}
Arrays are zero based in C++, so this is going to write beyond the end and never write the first element in your original code.

HTML element, that too is possible

from PIL import Image
from io import BytesIO
with open("image.jpg", "rb") as image_file:
data = base64.b64encode(image_file.read())
im = Image.open(BytesIO(base64.b64decode(data)))
im.save('image1.png', 'PNG')
<div ng-repeat="file in files" ng-class="!$last ? 'class-for-last' : 'other'">
{{file.name}}
</div>
That works for me! Good luck!
Use
[self dismissViewControllerAnimated:NO completion:nil];
Create a .o file:
g++ -c header.cpp
add this file to a library, creating library if necessary:
ar rvs header.a header.o
use library:
g++ main.cpp header.a
When you use only integers in a division, you will get integer division. When you use (at least one) double or float, you will get floating point division (and the answer you want to get).
So you can
Do not just cast the result of the integer division to double: the division was already performed as integer division, so the numbers behind the decimal are already lost.
Calling window.setTimeout(function, delay)
will allow you to accomplish this. Here's an example that will automatically close the alert 2 seconds (or 2000 milliseconds) after it is displayed.
$(".alert-message").alert();
window.setTimeout(function() { $(".alert-message").alert('close'); }, 2000);
If you want to wrap it in a nifty function you could do this.
function createAutoClosingAlert(selector, delay) {
var alert = $(selector).alert();
window.setTimeout(function() { alert.alert('close') }, delay);
}
Then you could use it like so...
createAutoClosingAlert(".alert-message", 2000);
I am certain there are more elegant ways to accomplish this.
You need to use GROUP BY
instead of DISTINCT
if you want to use aggregation functions.
SELECT title, MIN(date)
FROM table
GROUP BY title
I also experienced this issue after installing Telerik Reporting. I was not able to launch any solution in Visual Studio 2013, nor could I close Visual Studio 2013.
After uninstalling the reporting package and deleting Local / Roaming AppData for Visual Studio 2012, the problem was fixed.
Try with this:
var result = new List<object>();
foreach (var test in model.ToList()) {
result.Add(new {Id = test.IdSoc,Nom = test.Nom});
}
The following will produce, in the output directory,
