I came across the same question a few weeks ago and this is the result from what I found. This method does a quick dump of HTML to a PDF. The document will most likely need some format tweaking.
private MemoryStream createPDF(string html)
{
MemoryStream msOutput = new MemoryStream();
TextReader reader = new StringReader(html);
// step 1: creation of a document-object
Document document = new Document(PageSize.A4, 30, 30, 30, 30);
// step 2:
// we create a writer that listens to the document
// and directs a XML-stream to a file
PdfWriter writer = PdfWriter.GetInstance(document, msOutput);
// step 3: we create a worker parse the document
HTMLWorker worker = new HTMLWorker(document);
// step 4: we open document and start the worker on the document
document.Open();
worker.StartDocument();
// step 5: parse the html into the document
worker.Parse(reader);
// step 6: close the document and the worker
worker.EndDocument();
worker.Close();
document.Close();
return msOutput;
}
In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic
about following the C++ standard), you can do:
int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++
If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:
int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!
Or, better yet, use a standard container:
int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>
If you still want a proper array, you can use a constant, not a variable, when creating it:
const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)
Similarly, if you want to get the size from a function in C++11, you can use a constexpr
:
constexpr int n()
{
return 10;
}
double a[n()]; // n() is a compile time constant expression
If you use maven, add the following to your pom.xml file:
<plugin>
<!-- Build an executable JAR -->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<archive>
<manifest>
<mainClass>com.path.to.YourMainClass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
Then you can run mvn package
. The jar file will be located under in the target directory.
My guess is that you are trying to restore in lower versions which wont work
I use oracle 12 and it tell me that if you need to invoke the procedure then use call keyword. In your case it should be:
begin
call temp_proc;
end;
I think your date format does not make sense. There is no 13:00 PM. Remove the "aaa" at the end of your format or turn the HH into hh.
Nevertheless, this works fine for me:
String testDate = "29-Apr-2010,13:00:14 PM";
DateFormat formatter = new SimpleDateFormat("d-MMM-yyyy,HH:mm:ss aaa");
Date date = formatter.parse(testDate);
System.out.println(date);
It prints "Thu Apr 29 13:00:14 CEST 2010".
Some time ago Jupyter Notebooks started stripping JavaScript from HTML content [#3118]. Here are two solutions:
Serving Local HTML
If you want to embed an HTML page with JavaScript on your page now, the easiest thing to do is to save your HTML file to the directory with your notebook and then load the HTML as follows:
from IPython.display import IFrame
IFrame(src='./nice.html', width=700, height=600)
Serving Remote HTML
If you prefer a hosted solution, you can upload your HTML page to an Amazon Web Services "bucket" in S3, change the settings on that bucket so as to make the bucket host a static website, then use an Iframe component in your notebook:
from IPython.display import IFrame
IFrame(src='https://s3.amazonaws.com/duhaime/blog/visualizations/isolation-forests.html', width=700, height=600)
This will render your HTML content and JavaScript in an iframe, just like you can on any other web page:
<iframe src='https://s3.amazonaws.com/duhaime/blog/visualizations/isolation-forests.html', width=700, height=600></iframe>

An article on Testing Private Methods lays out some approaches to testing private code. using reflection puts extra burden on the programmer to remember if refactoring is done, the strings aren't automatically changed, but I think it's the cleanest approach.
Look up the man page for getcwd
.
I usually write something like this:
foreach($_GET as $key=>$content){
echo "<input type='hidden' name='$key' value='$content'/>";
}
This is working, but don't forget to sanitize your inputs against XSS attacks!
From the Jenkins home page:
Or
For iOS, try:
var systemVersion = UIDevice.current.systemVersion
For OS X, try:
var systemVersion = NSProcessInfo.processInfo().operatingSystemVersion
If you just want to check if the users is running at least a specific version, you can also use the following Swift 2 feature which works on iOS and OS X:
if #available(iOS 9.0, *) {
// use the feature only available in iOS 9
// for ex. UIStackView
} else {
// or use some work around
}
BUT it is not recommended to check the OS version. It is better to check if the feature you want to use is available on the device than comparing version numbers. For iOS, as mentioned above, you should check if it responds to a selector; eg.:
if (self.respondsToSelector(Selector("showViewController"))) {
self.showViewController(vc, sender: self)
} else {
// some work around
}
For "English locale" file names, this works nicely. I'm using this for sanitizing uploaded file names. The file name is not meant to be linked to anything on disk, it's for when the file is being downloaded hence there are no path checks.
$file_name = preg_replace('/([^\x20-~]+)|([\\/:?"<>|]+)/g', '_', $client_specified_file_name);
Basically it strips all non-printable and reserved characters for Windows and other OSs. You can easily extend the pattern to support other locales and functionalities.
Same issue I'm getting in my MYSQL while running sql script Please look into below image.. Error code 1206: The number of locks exceeds the lock table size Picture
This is Mysql configuration issue so I made some changes in my.ini
and It's working on my system & issue resolved.
We need to make some changes in my.ini
which is available on following Path:- C:\ProgramData\MySQL\MySQL Server 5.7\my.ini
and please update following changes in my.ini
config file fields:-
key_buffer_size=64M
read_buffer_size=64M
read_rnd_buffer_size=128M
innodb_log_buffer_size=10M
innodb_buffer_pool_size=256M
query_cache_type=2
max_allowed_packet=16M
After all above changes please restart the MYSQL Service. Please refer the image:- Microsoft MYSQL Service Picture
os.system()
returns the (encoded) process exit value. 0
means success:
On Unix, the return value is the exit status of the process encoded in the format specified for
wait()
. Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.
The output you see is written to stdout
, so your console or terminal, and not returned to the Python caller.
If you wanted to capture stdout
, use subprocess.check_output()
instead:
x = subprocess.check_output(['whoami'])
Generally, The DNS Domain of the URL MUST match the Certificate Subject of the certificate.
In former times this could be either by setting the domain as cn of the certificate or by having the domain set as a Subject Alternative Name.
Support for cn was deprecated for a long time (since 2000 in RFC 2818) and Chrome browser will not even look at the cn anymore so today you need to have the DNS Domain of the URL as a Subject Alternative Name.
RFC 6125 which forbids checking the cn if SAN for DNS Domain is present, but not if SAN for IP Address is present. RFC 6125 also repeats that cn is deprecated which was already said in RFC 2818. And the Certification Authority Browser Forum to be present which in combination with RFC 6125 essentially means that cn will never be checked for DNS Domain name.
The onclick
attribute in HTML calls JavaScript functions, not PHP functions.
There's an alternative approach to this:
#include <iterator>
#include <algorithm>
// ...
copy(istream_iterator<int>(iFile), istream_iterator<int>(),
ostream_iterator<int>(cerr, "\n"));
You can use jQuery to get text in textbox (work well for me), check in image detail
Code:
$(document.evaluate( "xpath" ,document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null ).singleNodeValue).val()
Example:
$(document.evaluate( "//*[@id='mail']" ,document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null ).singleNodeValue).val()
Inject this above query to your code. Image detail:
With the recent update to melt.data.table
, we can now melt multiple columns. With that, we can do:
require(data.table) ## 1.9.5
melt(setDT(df), id=1:2, measure=patterns("^Q3.2", "^Q3.3"),
value.name=c("Q3.2", "Q3.3"), variable.name="loop_number")

Its an injector error. You may have use lots of JavaScript files so the injector may be missing.
Some are here:

);
Please check the injector you need to insert in your app.js
I used this:
$('.nav-list li.active').removeClass('active');
$(this).parent().addClass('active');
Since the active class is in the <li>
element and what is clicked is the <a>
element, the first line removes .active
from all <li>
and the second one (again, $(this)
represents <a>
which is the clicked element) adds .active
to the direct parent, which is <li>
.

In all cases where optionalArg is falsy you will end up with defaultValue.
function myFunc(requiredArg, optionalArg) {
optionalArg = optionalArg || 'defaultValue';
console.log(optionalArg);
// Do stuff
}
myFunc(requiredArg);
myFunc(requiredArg, null);
myFunc(requiredArg, undefined);
myFunc(requiredArg, "");
myFunc(requiredArg, 0);
myFunc(requiredArg, false);
All of the above log defaultValue, because all of 6 are falsy. In case 4, 5, 6 you might not be interested to set optionalArg as defaultValue, but it sets since they are falsy.
There are 2 ways to pass by reference
Here's a sample code to do it:
public class Test {
public static void main(String args[]) {
Integer a = new Integer(1);
Integer b = a;
Test.modify(a);
System.out.println(a);
System.out.println(b);
IntegerObj ao = new IntegerObj(1);
IntegerObj bo = ao;
Test.modify(ao);
System.out.println(ao.value);
System.out.println(bo.value);
}
static void modify(Integer x) {
x=7;
}
static void modify(IntegerObj x) {
x.value=7;
}
}
class IntegerObj {
int value;
IntegerObj(int val) {
this.value = val;
}
}
Output:

The Java Specialists newsletter (which I can unreservedly recommend) had an interesting article on this, and how to handle the InterruptedException
. It's well worth reading and digesting.
Well, I am using this:
stripUrl(urlToStrip){
let stripped = urlToStrip.split('?')[0];
stripped = stripped.split('&')[0];
stripped = stripped.split('#')[0];
return stripped;
}
or:
stripUrl(urlToStrip){
return urlToStrip.split('?')[0].split('&')[0].split('#')[0];
}
Try this:
table {
border-collapse: separate;
border-spacing: 10px;
}
table td, table th {
padding: 10px;
}
Or try this:
table {
border-collapse: collapse;
}
table td, table th {
padding: 10px;
}
NanoHttpd works like a charm on Android -- we have code in production, in users hands, that's built on it.
The license absolutely allows commercial use of NanoHttpd, without any "viral" implications.
The same reason we don't go to the bathroom outside anymore, or why we don't speak Latin or Aramaic.
Technology comes along and makes things easier and more accessible.
EDIT - to cease offending people, I've removed certain words.
You can use:
UPDATE s SET

WHERE MyID=@MyID
) q
WHERE s.MyID2=@ MyID2
For a VB or C# app, one way to do this is by using Office Interop. This depends on which version of Excel you're working with.
For Excel 2003, this MSDN article is a good place to start. Understanding the Excel Object Model from a Visual Studio 2005 Developer's Perspective
You'll basically need to do the following:
Excel.Range allCellsRng;
string lowerRightCell = "IV65536";
allCellsRng = ws.get_Range("A1", lowerRightCell).Cells;
foreach (Range cell in allCellsRng)
{
if (null == cell.Value2 || isBlank(cell.Value2))
{
// Do something.
}
else if (isText(cell.Value2))
{
// Do something.
}
else if (isNumeric(cell.Value2))
{
// Do something.
}
}
For Excel 2007, try this MSDN reference.
If your independent variable (RHS variable) is a factor or a character taking only one value then that type of error occurs.
Example: iris data in R
(model1 <- lm(Sepal.Length ~ Sepal.Width + Species, data=iris))
# Call:
# lm(formula = Sepal.Length ~ Sepal.Width + Species, data = iris)
# Coefficients:
# (Intercept) Sepal.Width Speciesversicolor Speciesvirginica
# 2.2514 0.8036 1.4587 1.9468
Now, if your data consists of only one species:
(model1 <- lm(Sepal.Length ~ Sepal.Width + Species,
data=iris[iris$Species == "setosa", ]))
# Error in `contrasts<-`(`*tmp*`, value = contr.funs[1 + isOF[nn]]) :
# contrasts can be applied only to factors with 2 or more levels
If the variable is numeric (Sepal.Width
) but taking only a single value say 3, then the model runs but you will get NA
as coefficient of that variable as follows:
(model2 <-lm(Sepal.Length ~ Sepal.Width + Species,
data=iris[iris$Sepal.Width == 3, ]))
# Call:
# lm(formula = Sepal.Length ~ Sepal.Width + Species,
# data = iris[iris$Sepal.Width == 3, ])
# Coefficients:
# (Intercept) Sepal.Width Speciesversicolor Speciesvirginica
# 4.700 NA 1.250 2.017
Solution: There is not enough variation in dependent variable with only one value. So, you need to drop that variable, irrespective of whether that is numeric or character or factor variable.
Updated as per comments: Since you know that the error will only occur with factor/character, you can focus only on those and see whether the length of levels of those factor variables is 1 (DROP) or greater than 1 (NODROP).
To see, whether the variable is a factor or not, use the following code:
(l <- sapply(iris, function(x) is.factor(x)))
# Sepal.Length Sepal.Width Petal.Length Petal.Width Species
# FALSE FALSE FALSE FALSE TRUE
Then you can get the data frame of factor variables only
m <- iris[, l]
Now, find the number of levels of factor variables, if this is one you need to drop that
ifelse(n <- sapply(m, function(x) length(levels(x))) == 1, "DROP", "NODROP")
Note: If the levels of factor variable is only one then that is the variable, you have to drop.
It is more Ruby-like to ask objects whether they respond to a method you need or not, using respond_to?
. This allows both minimal interface and implementation unaware programming.
It is not always applicable of course, thus there is still a possibility to ask about more conservative understanding of "type", which is class or a base class, using the methods you're asking about.
Its Got simpler with Android Studio All you need is to first choose
3.based on the type of project and library you used like (ActionBarSherlock) you may prompted special import wizard so go ahead and click next then finish. in this case it was simple one
but sometimes the debug or Run options do not work and a error msg shows like
"this project structure is not gradle based or migrate it to gradle"
something to solve this close the opened eclipse project and reopen same project through the same process as we did before with import project (eclipse adt,gradle,etc)) this time android studio gonna add all necessary gradle files and green debug option will work too. i have did this somehow accidentally but it worked, i just hope it works for you too.
For those using sdkman
, this helped me.
Use Case:
I was using identifier 8.0.202-amzn
I decided to install Azul Zulu as follows: sdk install java 13.0.2-zulu
Error:
And then i got this unbound error.
Solution:
1. Right-click on your project in Eclipse
/STS
2. Choose Build Path
> Configure Build Path...
3. Under Libraries, remove the JRE Library, for my case 8.0.202-amzn
4. Under Libraries, click on Modulepath
> Add Library...
5. Choose JRE System Library
, click Next
6. Choose Alternate JRE
, click on Installed JREs...
7. Your previous configured value should be there
8. If it is there, edit it, if it is not there, add one
9. Make sure the name
is: 13.0.2-zulu
10. And the location
(JRE home) is: /Users/jumping_monkey/.sdkman/candidates/java/current
11. Click Apply and close
12. Click Finish
13. Voila!
You will see JRE System Library [13.0.2-zulu] in your Project Explorer and all errors gone
Bravo!

For anyone interested in a 16-bit x86 solution, there is a piece of code by JasonKnight here1 (he also includes a signed multiply piece, which I haven't tested). However, that code has issues with large inputs, where the "add bx,bx" part would overflow.
The fixed version:
softwareMultiply:
; INPUT CX,BX
; OUTPUT DX:AX - 32 bits
; CLOBBERS BX,CX,DI
xor ax,ax ; cheap way to zero a reg
mov dx,ax ; 1 clock faster than xor
mov di,cx
or di,bx ; cheap way to test for zero on both regs
jz @done
mov di,ax ; DI used for reg,reg adc
@loop:
shr cx,1 ; divide by two, bottom bit moved to carry flag
jnc @skipAddToResult
add ax,bx
adc dx,di ; reg,reg is faster than reg,imm16
@skipAddToResult:
add bx,bx ; faster than shift or mul
adc di,di
or cx,cx ; fast zero check
jnz @loop
@done:
ret
Or the same in GCC inline assembly:
asm("mov $0,%%ax\n\t"
"mov $0,%%dx\n\t"
"mov %%cx,%%di\n\t"
"or %%bx,%%di\n\t"
"jz done\n\t"
"mov %%ax,%%di\n\t"
"loop:\n\t"
"shr $1,%%cx\n\t"
"jnc skipAddToResult\n\t"
"add %%bx,%%ax\n\t"
"adc %%di,%%dx\n\t"
"skipAddToResult:\n\t"
"add %%bx,%%bx\n\t"
"adc %%di,%%di\n\t"
"or %%cx,%%cx\n\t"
"jnz loop\n\t"
"done:\n\t"
: "=d" (dx), "=a" (ax)
: "b" (bx), "c" (cx)
: "ecx", "edi"
);
What is Angular CLI Budgets? Budgets is one of the less known features of the Angular CLI. It’s a rather small but a very neat feature!
As applications grow in functionality, they also grow in size. Budgets is a feature in the Angular CLI which allows you to set budget thresholds in your configuration to ensure parts of your application stay within boundaries which you set — Official Documentation
Or in other words, we can describe our Angular application as a set of compiled JavaScript files called bundles which are produced by the build process. Angular budgets allows us to configure expected sizes of these bundles. More so, we can configure thresholds for conditions when we want to receive a warning or even fail build with an error if the bundle size gets too out of control!
How To Define A Budget? Angular budgets are defined in the angular.json file. Budgets are defined per project which makes sense because every app in a workspace has different needs.
Thinking pragmatically, it only makes sense to define budgets for the production builds. Prod build creates bundles with “true size” after applying all optimizations like tree-shaking and code minimization.
Oops, a build error! The maximum bundle size was exceeded. This is a great signal that tells us that something went wrong…
First Approach: Are your files gzipped?
Generally speaking, gzipped file has only about 20% the size of the original file, which can drastically decrease the initial load time of your app. To check if you have gzipped your files, just open the network tab of developer console. In the “Response Headers”, if you should see “Content-Encoding: gzip”, you are good to go.
How to gzip? If you host your Angular app in most of the cloud platforms or CDN, you should not worry about this issue as they probably have handled this for you. However, if you have your own server (such as NodeJS + expressJS) serving your Angular app, definitely check if the files are gzipped. The following is an example to gzip your static assets in a NodeJS + expressJS app. You can hardly imagine this dead simple middleware “compression” would reduce your bundle size from 2.21MB to 495.13KB.
const compression = require('compression')
const express = require('express')
const app = express()
app.use(compression())
Second Approach:: Analyze your Angular bundle
If your bundle size does get too big you may want to analyze your bundle because you may have used an inappropriate large-sized third party package or you forgot to remove some package if you are not using it anymore. Webpack has an amazing feature to give us a visual idea of the composition of a webpack bundle.
It’s super easy to get this graph.
npm install -g webpack-bundle-analyzer
ng build --stats-json
(don’t use flag --prod
). By enabling --stats-json
you will get an additional file stats.jsonwebpack-bundle-analyzer ./dist/stats.json
and your browser will pop up the page at localhost:8888. Have fun with it.ref 1: How Did Angular CLI Budgets Save My Day And How They Can Save Yours

I like the concept of grouping RadioButtons in WPF. There is a property GroupName
that specifies which RadioButton controls are mutually exclusive (http://msdn.microsoft.com/de-de/library/system.windows.controls.radiobutton.aspx).
So I wrote a derived class for WinForms that supports this feature:

using System.Windows.Forms;
using System.Diagnostics;
using System.Windows.Forms.VisualStyles;

DefaultValue(Level.Parent)]
public Level GroupNameLevel { get; set; }
[Category("AdvancedRadioButton"),
Description("Gets or sets the name that specifies which RadioButton controls are mutually exclusive.")]
public string GroupName { get; set; }
protected override void OnCheckedChanged(EventArgs e)
{
base.OnCheckedChanged(e);
if (Checked)
{
var arbControls = (dynamic)null;
switch (GroupNameLevel)
{
case Level.Parent:
if (this.Parent != null)
arbControls = GetAll(this.Parent, typeof(AdvancedRadioButton));
break;
case Level.Form:
Form form = this.FindForm();
if (form != null)
arbControls = GetAll(this.FindForm(), typeof(AdvancedRadioButton));
break;
}
if (arbControls != null)
foreach (Control control in arbControls)
if (control != this &&
(control as AdvancedRadioButton).GroupName == this.GroupName)
(control as AdvancedRadioButton).Checked = false;
}
}
protected override void OnClick(EventArgs e)
{
if (!Checked)
base.OnClick(e);
}
protected override void OnPaint(PaintEventArgs pevent)
{
CheckBoxRenderer.DrawParentBackground(pevent.Graphics, pevent.ClipRectangle, this);
RadioButtonState radioButtonState;
if (Checked)
{
radioButtonState = RadioButtonState.CheckedNormal;
if (Focused)
radioButtonState = RadioButtonState.CheckedHot;
if (!Enabled)
radioButtonState = RadioButtonState.CheckedDisabled;
}
else
{
radioButtonState = RadioButtonState.UncheckedNormal;
if (Focused)
radioButtonState = RadioButtonState.UncheckedHot;
if (!Enabled)
radioButtonState = RadioButtonState.UncheckedDisabled;
}
Size glyphSize = RadioButtonRenderer.GetGlyphSize(pevent.Graphics, radioButtonState);
Rectangle rect = pevent.ClipRectangle;
rect.Width -= glyphSize.Width;
rect.Location = new Point(rect.Left + glyphSize.Width, rect.Top);
RadioButtonRenderer.DrawRadioButton(pevent.Graphics, new System.Drawing.Point(0, rect.Height / 2 - glyphSize.Height / 2), rect, this.Text, this.Font, this.Focused, radioButtonState);
}
private IEnumerable<Control> GetAll(Control control, Type type)
{
var controls = control.Controls.Cast<Control>();
return controls.SelectMany(ctrl => GetAll(ctrl, type))
.Concat(controls)
.Where(c => c.GetType() == type);
}
}

Actually, you have to use the anchor # to play with this. If you reverse engineer the Gmail url system, you'll find
https://mail.google.com/mail/u/0/#inbox
https://mail.google.com/mail/u/0/#inbox?compose=new
Everything after # is the part your want to load in your page, then you just have to chose where to load it.
By the way, using document.location by adding a #something won't refresh your page.
Try this example
String[] formats = new String[] {
"yyyy-MM-dd",
"yyyy-MM-dd HH:mm",
"yyyy-MM-dd HH:mmZ",
"yyyy-MM-dd HH:mm:ss.SSSZ",

It would be better to choose JSON-RPC between REST and JSON-RPC to develop an API for a web application that is easier to understand. JSON-RPC is preferred because its mapping to method calls and communications can be easily understood.
Choosing the most suitable approach depends on the constraints or principal objective. For example, as far as performance is a major trait, it is advisable to go for JSON-RPC (for example, High Performance Computing). However, if the principal objective is to be agnostic in order to offer a generic interface to be inferred by others, it is advisable to go for REST. If you both goals are needed to be achieved, it is advisable to include both protocols.
The fact which actually splits REST from JSON-RPC is that it trails a series of carefully thought out constraints- confirming architectural flexibility. The constraints take in ensuring that the client as well as server are able to grow independently of each other (changes can be made without messing up with the application of client), the calls are stateless (the state is regarded as hypermedia), a uniform interface is offered for interactions, the API is advanced on a layered system (Hall, 2010). JSON-RPC is rapid and easy to consume, however as mentioned resources as well as parameters are tightly coupled and it is likely to depend on verbs (api/addUser, api/deleteUser) using GET/ POST whereas REST delivers loosely coupled resources (api/users) in a HTTP. REST API depends up on several HTTP methods such as GET, PUT, POST, DELETE, PATCH. REST is slightly tougher for inexperienced developers to implement.
JSON (denoted as JavaScript Object Notation) being a lightweight data-interchange format, is easy for humans to read as well as write. It is hassle free for machines to parse and generate. JSON is a text format which is entirely language independent but practices conventions that are acquainted to programmers of the family of languages, consisting of C#, C, C++, Java, Perl, JavaScript, Python, and numerous others. Such properties make JSON a perfect data-interchange language and a better choice to opt for.
After all these awesome answers, I hope my answer finds someone and helps them out. I wrote a small service to keep track of route history. Here it goes.
import { Injectable } from '@angular/core';
import { NavigationEnd, Router } from '@angular/router';
import { filter } from 'rxjs/operators';
@Injectable()
export class RouteInterceptorService {
private _previousUrl: string;
private _currentUrl: string;
private _routeHistory: string[];
constructor(router: Router) {
this._routeHistory = [];
router.events
.pipe(filter(event => event instanceof NavigationEnd))
.subscribe((event: NavigationEnd) => {
this._setURLs(event);
});
}
private _setURLs(event: NavigationEnd): void {
const tempUrl = this._currentUrl;
this._previousUrl = tempUrl;
this._currentUrl = event.urlAfterRedirects;
this._routeHistory.push(event.urlAfterRedirects);
}
get previousUrl(): string {
return this._previousUrl;
}
get currentUrl(): string {
return this._currentUrl;
}
get routeHistory(): string[] {
return this._routeHistory;
}
}
Your static method should go from:
public static class SimpleUsing
{
public static void DoUsing(Action<MyDataContext> action)
{
using (MyDataContext db = new MyDataContext())
action(db);
}
}
To:
public static class SimpleUsing
{
public static TResult DoUsing<TResult>(Func<MyDataContext, TResult> action)
{
using (MyDataContext db = new MyDataContext())
return action(db);
}
}
This answer grew out of comments so I could provide code. For a complete elaboration, please see @sll's answer below.
Adding to ADev's answer (which in my opinion is the most correct), since the widespread adoption of Kotlin, and its useful extension functions:
fun ImageView.setTint(context: Context, @ColorRes colorId: Int) {
val color = ContextCompat.getColor(context, colorId)
val colorStateList = ColorStateList.valueOf(color)
ImageViewCompat.setImageTintList(this, colorStateList)
}
I think this is a function which could be useful to have in any Android project!
This steps will delete all topics and data
/**
* method is used for checking valid email id format.
*
* @param email
* @return boolean true for valid false for invalid
*/
public static boolean isEmailValid(String email) {
String expression = "^[\\w\\.-]+@([\\w\\-]+\\.)+[A-Z]{2,4}$";
Pattern pattern = Pattern.compile(expression, Pattern.CASE_INSENSITIVE);
Matcher matcher = pattern.matcher(email);
return matcher.matches();
}
Pass your edit text string in this function .
for right email verification you need server side authentication
Note there is now a built-in method in Android, see answers below.
For byte arrays System.Buffer.BlockCopy will give you the very best performance.
I also experienced this problem and found the easy solution to be
public string ReturnValues()
{
string _var = ""; // Setting an innitial value
if (.....) // Looking at conditions
{
_var = "true"; // Re-assign the value of _var
}
return _var; // Return the value of var
}
This also works with other return types and gives the least amount of problems
The initial value I chose was a fall-back value and I was able to re-assign the value as many times as required.
Updated version of @martin's answer for Swift 5+ using Combine. This one also includes unavailibity reason check for iOS 14.
import Combine
import Network
enum NetworkType {
case wifi
case cellular
case loopBack
case wired
case other
}
final class ReachabilityService: ObservableObject {
@Published var reachabilityInfos: NWPath?
@Published var isNetworkAvailable: Bool?
@Published var typeOfCurrentConnection: NetworkType?
private let monitor = NWPathMonitor()
private let backgroundQueue = DispatchQueue.global(qos: .background)
init() {
setUp()
}
init(with interFaceType: NWInterface.InterfaceType) {
setUp()
}
deinit {
monitor.cancel()
}
}
private extension ReachabilityService {
func setUp() {
monitor.pathUpdateHandler = { [weak self] path in
self?.reachabilityInfos = path
switch path.status {
case .satisfied:
print("ReachabilityService: satisfied")
self?.isNetworkAvailable = true
break
case .unsatisfied:
print("ReachabilityService: unsatisfied")
if #available(iOS 14.2, *) {
switch path.unsatisfiedReason {
case .notAvailable:
print("ReachabilityService: unsatisfiedReason: notAvailable")
break
case .cellularDenied:
print("ReachabilityService: unsatisfiedReason: cellularDenied")
break
case .wifiDenied:
print("ReachabilityService: unsatisfiedReason: wifiDenied")
break
case .localNetworkDenied:
print("ReachabilityService: unsatisfiedReason: localNetworkDenied")
break
@unknown default:
print("ReachabilityService: unsatisfiedReason: default")
}
} else {
// Fallback on earlier versions
}
self?.isNetworkAvailable = false
break
case .requiresConnection:
print("ReachabilityService: requiresConnection")
self?.isNetworkAvailable = false
break
@unknown default:
print("ReachabilityService: default")
self?.isNetworkAvailable = false
}
if path.usesInterfaceType(.wifi) {
self?.typeOfCurrentConnection = .wifi
} else if path.usesInterfaceType(.cellular) {
self?.typeOfCurrentConnection = .cellular
} else if path.usesInterfaceType(.loopback) {
self?.typeOfCurrentConnection = .loopBack
} else if path.usesInterfaceType(.wiredEthernet) {
self?.typeOfCurrentConnection = .wired
} else if path.usesInterfaceType(.other) {
self?.typeOfCurrentConnection = .other
}
}
monitor.start(queue: backgroundQueue)
}
}
Usage:
In your view model:
private let reachability = ReachabilityService()
init() {
reachability.$isNetworkAvailable.sink { [weak self] isConnected in
self?.isConnected = isConnected ?? false
}.store(in: &cancelBag)
}
In your controller:
viewModel.$isConnected.sink { [weak self] isConnected in
print("isConnected: \(isConnected)")
DispatchQueue.main.async {
//Update your UI in here
}
}.store(in: &bindings)
For demo code that conforms to POSIX standard as described in Setting Terminal Modes Properly
and Serial Programming Guide for POSIX Operating Systems, the following is offered.
This code should execute correctly using Linux on x86 as well as ARM (or even CRIS) processors.
It's essentially derived from the other answer, but inaccurate and misleading comments have been corrected.
This demo program opens and initializes a serial terminal at 115200 baud for non-canonical mode that is as portable as possible.
The program transmits a hardcoded text string to the other terminal, and delays while the output is performed.
The program then enters an infinite loop to receive and display data from the serial terminal.
By default the received data is displayed as hexadecimal byte values.
To make the program treat the received data as ASCII codes, compile the program with the symbol DISPLAY_STRING, e.g.
cc -DDISPLAY_STRING demo.c
If the received data is ASCII text (rather than binary data) and you want to read it as lines terminated by the newline character, then see this answer for a sample program.

change the culture and try out like this might work for you
string[] formats= { "MM/dd/yyyy HH:mm" }
var dateTime = DateTime.ParseExact("04/30/2013 23:00",
formats, new CultureInfo("en-US"), DateTimeStyles.None);
Check for details : DateTime.ParseExact Method (String, String[], IFormatProvider, DateTimeStyles)
application/javascript is the correct type to use but since it's not supported by IE6-8 you're going to be stuck with text/javascript. If you don't care about validity (HTML5 excluded) then just don't specify a type.
Considering your code snippet, please note that you can only pass Native objects to the findBy### method, lets say you want to load a list of accounts that belongs certain costumers, one solution is to do this,
@Query("Select a from Account a where a."#nameoffield"=?1")
List<Account> findByCustomer(String "#nameoffield");
Make sue the name of the table to be queried is thesame as the Entity class. For further implementations please take a look at this
You can do the same in python by simply importing the second file, code at the top level will run when imported. I'd suggest this is messy at best, and not a good programming practice. You would be better off organizing your code into modules
Example:
F1.py:
print "Hello, "
import f2
F2.py:
print "World!"
When run:
python ./f1.py
Hello,
World!
Edit to clarify: The part I was suggesting was "messy" is using the import
statement only for the side effect of generating output, not the creation of separate source files.
If you have the HTML
<form name="formname" .... id="form-first">
<iframe id="one" src="iframe2.html">
</iframe>
</form>
and JavaScript
function iframeRef( frameRef ) {
return frameRef.contentWindow
? frameRef.contentWindow.document
: frameRef.contentDocument
}
var inside = iframeRef( document.getElementById('one') )
inside
is now a reference to the document, so you can do getElementsByTagName('textarea')
and whatever you like, depending on what's inside the iframe src.
echo $_product->getImageUrl();
This method of the Product class should do the trick for you.
Use font
property of UILabel
:
label.font = UIFont(name:"HelveticaNeue-Bold", size: 16.0)
or use default system font
to bold text:
label.font = UIFont.boldSystemFont(ofSize: 16.0)
You can search your hard drive for one of the programs that's installed with the SDK. For instance, if you search for aapt.exe
or adb.exe
, they will be in the platform-tools
directory underneath the installation directory (which is what you're after).
Sounds like you need to grant the execute permission to the user (or a group that they a part of) for the stored procedure in question.
For example, you could grant access thus:
USE zzzzzzz;
GRANT EXEC ON dbo.xxxxxxx TO PUBLIC
Its always good to have these additional properties besides the
background-image:url('path') no-repeat 0 0;
set dimension to the element
width:x; height:y;
background-size:100%
it will create the file in the root directory of your project/solution.
You can specify a location of choice in the web.config of your app as follows:
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="c:/ServiceLogs/Olympus.Core.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<datePattern value=".yyyyMMdd.log" />
<maximumFileSize value="5MB" />
<staticLogFileName value="true" />
<lockingModel type="log4net.Appender.RollingFileAppender+MinimalLock" />
<maxSizeRollBackups value="-1" />
<countDirection value="1" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level [%thread] %logger - %message%newline%exception" />
</layout>
</appender>
the file tag specifies the location.
You will probably get an UAC prompt when importing the reg file. If you accept that, you have more rights.
Since you are writing to the 'policies' key, you need to have elevated rights. This part of the registry protected, because it contains settings that are administered by your system administrator.
Alternatively, you may try to run regedit.exe
from the command prompt.
regedit.exe /S yourfile.reg
.. should silently import the reg file. See RegEdit Command Line Options Syntax for more command line options.
I have checked how ADB installs apps.
- It copies the APK to /data/local/tmp
- it runs 'shell:pm install /data/local/tmp/app.apk'
I have tried to replicate this behaviour by doing: (on pc, using usb-cable)
adb push app.apk /sdcard/app.apk
adb shell
$ pm install /sdcard/app.apk
This works. The app is installed.
I made an application (named AppInstall) which should install the other app.
(installed normally, non-rooted device)
It does:
Runtime.getRuntime().exec("pm install /sdcard/app.apk").waitFor();
But this gives the error:
java.lang.SecurityException: Neither user 10019 nor current process has android.permission.INSTALL_PACKAGES.
It seems like the error is thrown by pm, not by AppInstall.
Because the SecurityException is not catched by AppInstall and the app does not crash.
I've tried the same thing on a rooted device (same app and AppInstall) and it worked like a charm.
(Also normally installed, not in /system or anything)
AppInstall didn't even ask root-permission.
But thats because the shell is always #
instead of $
on that device.
Btw, you need root to install an app in /system, correct?
I tried adb remount on the non-rooted device and got:
remount failed: Operation not permitted.
That's why I could not try the /system thing on the non-rooted device.
Conclusion: you should use a rooted device
Hope this helps :)
For the same reason you can also use inheritIO()
to map Java console with external app console like:
ProcessBuilder pb = new ProcessBuilder(appPath, arguments);
pb.directory(new File(appFile.getParent()));
pb.inheritIO();
Process process = pb.start();
int success = process.waitFor();
You are using the incorrect overload of ActionLink. Try this
<%= Html.ActionLink("Create New Part", "CreateParts", "PartList", new { parentPartId = 0 }, null)%>
There is nothing wrong with the other answers. I'm just sharing the storyboard version for setting the font.
(You will likely need to toggle the Bar Tint for the Navigation Bar before Xcode picks up the new font)
Verified that this does work on Xcode 7.1.1+. (See the Samples below)
Some of these are repeated which means they are very likely worth noting.
Note ~ A nice checklist can be found from the Code With Chris website and you can see the sample download project.
If you have your own font and want to use that in your storyboard, then there is a decent set of answers on the following SO Question. One answer identifies these steps.
So Xcode naturally looks like it can handle custom fonts on UINavigationItem but that feature is just not updating properly (The font selected is ignored).
To workaround this:
One way is to fix using the storyboard and adding a line of code: First add a UIView (UIButton, UILabel, or some other UIView subclass) to the View Controller (Not the Navigation Item...Xcode is not currently allowing one to do that). After you add the control you can modify the font in the storyboard and add a reference as an outlet to your View Controller. Just assign that view to the UINavigationItem.titleView. You could also set the text name in code if necessary. Reported Bug (23600285).
@IBOutlet var customFontTitleView: UIButton!
//Sometime later...
self.navigationItem.titleView = customFontTitleView
Maybe map the share as a network drive and then do
git clone Z:\
Mostly just a guess; I always do this stuff using ssh. Following that suggstion of course will mean that you'll need to have that drive mapped every time you push/pull to/from the laptop. I'm not sure how you rig up ssh to work under windows but if you're going to be doing this a lot it might be worth investigating.
I found a very easy solution to this problem.
python.exe
C:\xxx\...\python.exe your_script.py
I'm not sure whether the spells of these options are right, since I'm using Chinese version of Windows.
I am running node.js on Windows with npm. The trick is simply use cygwin. I followed the howto under https://github.com/joyent/node/wiki/Building-node.js-on-Cygwin-(Windows) . But make sure that you use version 0.4.11 of nodejs or npm will fail!
It's simple. You can create your own ViewModel class for Login - LoginViewModel. You can create view var dialog = new UserView(); inside your LoginViewModel. And you can set-up Command LoginCommand into button.
<Button Name="btnLogin" IsDefault="True" Content="Login" Command="{Binding LoginCommand}" />
and
<Button Name="btnCancel" IsDefault="True" Content="Login" Command="{Binding CancelCommand}" />
ViewModel class:
public class LoginViewModel
{
Window dialog;
public bool ShowLogin()
{
dialog = new UserView();
dialog.DataContext = this; // set up ViewModel into View
if (dialog.ShowDialog() == true)
{
return true;
}
return false;
}
ICommand _loginCommand
public ICommand LoginCommand
{
get
{
if (_loginCommand == null)
_loginCommand = new RelayCommand(param => this.Login());
return _loginCommand;
}
}
public void CloseLoginView()
{
if (dialog != null)
dialog.Close();
}
public void Login()
{
if(CheckLogin()==true)
{
CloseLoginView();
}
else
{
// write error message
}
}
public bool CheckLogin()
{
// ... check login code
return true;
}
}
You can do something like
git push origin +<short_commit_sha>^:<branch_name>
From comments I picked an answer like and also adding TimeZone:
String dateTime = "2015-07-18T13:32:56.971-0400";
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSSZZ")
.withLocale(Locale.ROOT)
.withChronology(ISOChronology.getInstanceUTC());
DateTime dt = formatter.parseDateTime(dateTime);

if var == 'stringone' or var == 'stringtwo':
dosomething()
'is' is used to check if the two references are referred to a same object. It compare the memory address. Apparently, 'stringone' and 'var' are different objects, they just contains the same string, but they are two different instances of the class 'str'. So they of course has two different memory addresses, and the 'is' will return False.
EDIT: I just realized you want to filter details
, which is an array of hashes. In that case you could do
details.reject { |item| item[:qty].empty? }
The inner data structure itself is not an Array, but a Hash. You can also use select
here, but the block is given the key and value in this case:
irb(main):001:0> h = {:sku=>"507772-B21", :desc=>"HP 1TB 3G SATA 7.2K RPM LFF (3 .", :qty=>"", :qty2=>"1", :price=>"5,204.34 P"}
irb(main):002:0> h.select { |key, value| !value.empty? }
=> {:sku=>"507772-B21", :desc=>"HP 1TB 3G SATA 7.2K RPM LFF (3 .",
:qty2=>"1", :price=>"5,204.34 P"}
Or using reject
, which is the inverse of select
(excludes all items for which the given condition holds):
h.reject { |key, value| value.empty? }
Note that this is Ruby 1.9. If you have to maintain compatibility with 1.8, you could do:
Hash[h.reject { |key, value| value.empty? }]
The code below worked for me I used part of the code above inside the button class.
public Button signupB;
public void handleButtonClick (){
try {
FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(getClass().getResource("sceneNotAvailable.fxml"));
/*
* if "fx:controller" is not set in fxml
* fxmlLoader.setController(NewWindowController);
*/
Scene scene = new Scene(fxmlLoader.load(), 630, 400);
Stage stage = new Stage();
stage.setTitle("New Window");
stage.setScene(scene);
stage.show();
} catch (IOException e) {
Logger logger = Logger.getLogger(getClass().getName());
logger.log(Level.SEVERE, "Failed to create new Window.", e);
}
}
}
In new version, you can try something like this
function (req,res) {
model.destroy({
where: {
id: req.params.id
}
})
.then(function (deletedRecord) {
if(deletedRecord === 1){
res.status(200).json({message:"Deleted successfully"});
}
else
{
res.status(404).json({message:"record not found"})
}
})
.catch(function (error){
res.status(500).json(error);
});
Many C APIs use a null pointer to indicate "use the default", e.g. mosquittopp. Here is the pattern I am using, based on David Cormack's answer:
mosqpp::tls_set(
MqttOptions->CAFile.length() > 0 ? MqttOptions->CAFile.c_str() : NULL,
MqttOptions->CAPath.length() > 0 ? MqttOptions->CAPath.c_str() : NULL,
MqttOptions->CertFile.length() > 0 ? MqttOptions->CertFile.c_str() : NULL,
MqttOptions->KeyFile.length() > 0 ? MqttOptions->KeyFile.c_str() : NULL
);
It is a little cumbersome, but allows one to keep everything as a std::string
up until the API call itself.

var fh = fso.OpenTextFile("data.txt", 8, false, 0);
fh.WriteLine(d1 + ',' + d2);
fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
var id = document.getElementById("id").value;
var content = document.getElementById("content").value;
writeToFile(id, content);
}
checking a particular row:
function readFile(){
var fso = new ActiveXObject("Scripting.FileSystemObject");
var fh = fso.OpenTextFile("data.txt", 1, false, 0);
var lines = "";
while (!fh.AtEndOfStream) {
lines += fh.ReadLine() + "\r";
}
fh.Close();
return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
var input = document.getElementById("input").value;
if (input != "") {
var text = readFile();
var lines = text.split("\r");
lines.pop();
var result;
for (var i = 0; i < lines.length; i++) {
if (lines[i].match(new RegExp(input))) {
result = "Found: " + lines[i].split(",")[1];
}
}
if (result) { alert(result); }
else { alert(input + " not found!"); }
}
}
Put these inside a .hta
file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.
Angular - equal width button group
Assuming you have an array of 'things' in your scope...
<div class="btn-group"
style="width: 100%;">
<button ng-repeat="thing in things"
class="btn btn-default"
ng-style="{width: (100/things.length)+'%'}">
{{thing}}
</button>

In PHP, use mysqli_real_escape_string.
Example from the PHP Manual:
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
mysqli_query($link, "CREATE TEMPORARY TABLE myCity LIKE City");
$city = "'s Hertogenbosch";
/* this query will fail, cause we didn't escape $city */
if (!mysqli_query($link, "INSERT into myCity (Name) VALUES ('$city')")) {
printf("Error: %s\n", mysqli_sqlstate($link));
}
$city = mysqli_real_escape_string($link, $city);
/* this query with escaped $city will work */
if (mysqli_query($link, "INSERT into myCity (Name) VALUES ('$city')")) {
printf("%d Row inserted.\n", mysqli_affected_rows($link));
}
mysqli_close($link);
?>
my solution is here
function getVal() {
var $numInput = $('input');
var $inputArr = [];
for(let i=0; i < $numInput.length ; i++ )
$inputArr[$numInput[i].name] = $numInput[i].value;
return $inputArr;
}
var $inNum = getVal();
$('input').on('change', function() {
// inNum is last Val
$inNum = getVal();
// in here we update value of input
let $val = this.value;
});
A brute force workaround could be:
Stop the SQL Server Service.
Delete the corresponding .mdf and .ldf files.
Start the SQL Server Service.
Connect with SSMS and delete the database.
I lied, jQuery returns the correct value for both pages $(document).height();... why did I ever doubt it?
What Perforce features are people using?
I ask because if all folks are doing is get and put from the command line, git has that covered, and so do all the other RTS.
When Gradle builds your project, it puts all APKs in build/apk directory. You could also just do a simple recursive find command for *.apk in the top level directory of your project.

I think the answer from cheez (https://stackoverflow.com/users/122933/cheez) is the easiest and most effective one. I'd elaborate a little bit over it so it would not modify a numpy function for the whole session period.
My suggestion is below. I´m using it to download the reuters dataset from keras which is showing the same kind of error:
old = np.load
np.load = lambda *a,**k: old(*a,**k,allow_pickle=True)
from keras.datasets import reuters
(train_data, train_labels), (test_data, test_labels) = reuters.load_data(num_words=10000)
np.load = old
del(old)
Python 3 ints do not have a maximum.
If your purpose is to determine the maximum size of an int in C when compiled the same way Python was, you can use the struct module to find out:
>>> import struct
>>> platform_c_maxint = 2 ** (struct.Struct('i').size * 8 - 1) - 1
If you are curious about the internal implementation details of Python 3 int objects, Look at sys.int_info
for bits per digit and digit size details. No normal program should care about these.
In general, if the helper is to be used in (just) controllers, I prefer to declare it as an instance method of class ApplicationController
.
From the docs
<?php
$number = 1234.56;
// english notation (default)
$english_format_number = number_format($number);
// 1,235
// French notation
$nombre_format_francais = number_format($number, 2, ',', ' ');
// 1 234,56
$number = 1234.5678;
// english notation without thousands separator
$english_format_number = number_format($number, 2, '.', '');
// 1234.57
?>
You can also restart postgresql by using this command, should work on both the versions :
sudo service postgresql start
I need to decrypt a password. The password is crypted with password_hash function.
$password = 'examplepassword'; $crypted = password_hash($password, PASSWORD_DEFAULT);
Its not clear to me if you need password_verify
, or you are trying to gain unauthorized access to the application or database. Other have talked about password_verify
, so here's how you could gain unauthorized access. Its what bad guys often do when they try to gain access to a system.
First, create a list of plain text passwords. A plain text list can be found in a number of places due to the massive data breaches from companies like Adobe. Sort the list and then take the top 10,000 or 100,000 or so.
Second, create a list of digested passwords. Simply encrypt or hash the password. Based on your code above, it does not look like a salt is being used (or its a fixed salt). This makes the attack very easy.
Third, for each digested password in the list, perform a select in an attempt to find a user who is using the password:
$sql_script = 'select * from USERS where password="'.$digested_password.'"'
Fourth, profit.
So, rather than picking a user and trying to reverse their password, the bad guy picks a common password and tries to find a user who is using it. Odds are on the bad guy's side...
Because the bad guy does these things, it would behove you to not let users choose common passwords. In this case, take a look at ProCheck, EnFilter or Hyppocrates (et al). They are filtering libraries that reject bad passwords. ProCheck achieves very high compression, and can digest multi-million word password lists into a 30KB data file.
Using only the rpm utility, this should work in any OS that has rpm:
rpm -q --whatprovides [file name]
If you really don't want to use any server controls, you should put the Response.Write
in the place you want the string to be written:
<body>
<% Response.Write(stringVariable); %>
</body>
A shorthand for this syntax is:
<body>
<%= stringVariable %>
</body>
You may have a table called 'test'
COPY test(gid, "name", the_geom)

New with iOS 9 and higher you can present the user with a SFSafariViewController
(see documentation here). Basically you get all the benefits of sending the user to Safari without making them leave your app. To use the new SFSafariViewController just:
import SafariServices
and somewhere in an event handler present the user with the safari view controller like this:
let svc = SFSafariViewController(url: url)
present(svc, animated: true, completion: nil)
The safari view will look something like this:
Maybe you got your columns backwards??
ALTER TABLE Employees
ADD FOREIGN KEY (UserID) <-- this needs to be a column of the Employees table
REFERENCES ActiveDirectories(id) <-- this needs to be a column of the ActiveDirectories table
Could it be that the column is called ID
in the Employees
table, and UserID
in the ActiveDirectories
table?
Then your command should be:
ALTER TABLE Employees
ADD FOREIGN KEY (ID) <-- column in table "Employees"
REFERENCES ActiveDirectories(UserID) <-- column in table "ActiveDirectories"
You could use jQuery and an Ajax call to post the specific update back to your server with Javascript.
It would look something like this:
function updatePostID(val, comment)
{
var args = {};
args.PostID = val;
args.Comment = comment;
$.ajax({
type: "POST",
url: controllerActionMethodUrlHere,
contentType: "application/json; charset=utf-8",
data: args,
dataType: "json",
success: function(msg)
{
// Something afterwards here
}
});
}
From http://www.devdaily.com/blog/post/mysql/drop-mysql-tables-in-any-order-foreign-keys:
SET FOREIGN_KEY_CHECKS = 0;
drop table if exists customers;
drop table if exists orders;
drop table if exists order_details;
SET FOREIGN_KEY_CHECKS = 1;
(Note that this answers how to disable foreign key checks in order to be able to drop the tables in arbitrary order. It does not answer how to automatically generate drop-table statements for all existing tables and execute them in a single script. Jean's answer does.)
You need to define a new type and define your function to return that type.
CREATE TYPE my_type AS (f1 varchar(10), f2 varchar(10) /* , ... */ );
CREATE OR REPLACE FUNCTION get_object_fields(name text)
RETURNS my_type
AS
$$
DECLARE
result_record my_type;
BEGIN
SELECT f1, f2, f3
INTO result_record.f1, result_record.f2, result_record.f3
FROM table1
WHERE pk_col = 42;
SELECT f3
INTO result_record.f3
FROM table2
WHERE pk_col = 24;
RETURN result_record;
END
$$ LANGUAGE plpgsql;
If you want to return more than one record you need to define the function as returns setof my_type
Update
Another option is to use RETURNS TABLE()
instead of creating a TYPE
which was introduced in Postgres 8.4
CREATE OR REPLACE FUNCTION get_object_fields(name text)
RETURNS TABLE (f1 varchar(10), f2 varchar(10) /* , ... */ )
...

You need the following permissions in your manifest file:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
Then you can use the following in your activity class:
WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);
Use the following to check if it's enabled or not
boolean wifiEnabled = wifiManager.isWifiEnabled()
You'll find a nice tutorial on the subject on this site.
First, add the Material Design dependency.
implementation 'com.google.android.material:material:<version>'
To get the latest material design library version. check the official website github repository.
Current version is 1.2.0.
So, you have to add,
implementation 'com.google.android.material:material:1.2.0'
Then, you need to change the app theme to material theme by adding,
<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
in your style.xml. Dont forget to set the same theme in your application theme in your manifest file.
HttpClient client = new DefaultHttpClient();
Uri.Builder builder = Uri.parse(url).buildUpon();
for (String name : params.keySet()) {
builder.appendQueryParameter(name, params.get(name).toString());
}
url = builder.build().toString();
HttpGet request = new HttpGet(url);
HttpResponse response = client.execute(request);
return EntityUtils.toString(response.getEntity(), "UTF-8");
This should work:
function valthisform()
{
var checkboxs=document.getElementsByName("c1");
var okay=false;
for(var i=0,l=checkboxs.length;i<l;i++)
{
if(checkboxs[i].checked)
{
okay=true;
break;
}
}
if(okay)alert("Thank you for checking a checkbox");
else alert("Please check a checkbox");
}
If you have a question about the code, just comment.
I use l=checkboxs.length
to improve the performance. See http://www.erichynds.com/javascript/javascript-loop-performance-caching-the-length-property-of-an-array/
Here's an old discussion thread where I listed the main differences and the conditions in which you should use each of these methods. I think you may find it useful to go through the discussion.
To explain the differences as relevant to your posted example:
a. When you use RegisterStartupScript
, it will render your script after all the elements in the page (right before the form's end tag). This enables the script to call or reference page elements without the possibility of it not finding them in the Page's DOM.
Here is the rendered source of the page when you invoke the RegisterStartupScript
method:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
<form name="form1" method="post" action="StartupScript.aspx" id="form1">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
</div>
<div> <span id="lblDisplayDate">Label</span>
<br />
<input type="submit" name="btnPostback" value="Register Startup Script" id="btnPostback" />
<br />
<input type="submit" name="btnPostBack2" value="Register" id="btnPostBack2" />
</div>
<div>
<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="someViewstategibberish" />
</div>
<!-- Note this part -->
<script language='javascript'>
var lbl = document.getElementById('lblDisplayDate');
lbl.style.color = 'red';
</script>
</form>
<!-- Note this part -->
</body>
</html>
b. When you use RegisterClientScriptBlock
, the script is rendered right after the Viewstate tag, but before any of the page elements. Since this is a direct script (not a function that can be called, it will immediately be executed by the browser. But the browser does not find the label in the Page's DOM at this stage and hence you should receive an "Object not found" error.
Here is the rendered source of the page when you invoke the RegisterClientScriptBlock
method:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
<form name="form1" method="post" action="StartupScript.aspx" id="form1">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
</div>
<script language='javascript'>
var lbl = document.getElementById('lblDisplayDate');
// Error is thrown in the next line because lbl is null.
lbl.style.color = 'green';
Therefore, to summarize, you should call the latter method if you intend to render a function definition. You can then render the call to that function using the former method (or add a client side attribute).
Edit after comments:
For instance, the following function would work:
protected void btnPostBack2_Click(object sender, EventArgs e)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("<script language='javascript'>function ChangeColor() {");
sb.Append("var lbl = document.getElementById('lblDisplayDate');");
sb.Append("lbl.style.color='green';");
sb.Append("}</script>");
//Render the function definition.
if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock"))
{
ClientScript.RegisterClientScriptBlock(this.GetType(), "JSScriptBlock", sb.ToString());
}
//Render the function invocation.
string funcCall = "<script language='javascript'>ChangeColor();</script>";
if (!ClientScript.IsStartupScriptRegistered("JSScript"))
{
ClientScript.RegisterStartupScript(this.GetType(), "JSScript", funcCall);
}
}
A little CSS and you are done fiddle
<div style="position: absolute;top: 32px; left: 430px;" id="outerFilterDiv">
<input name="filterTextField" type="text" id="filterTextField" tabindex="2" style="width: 140px;
position: absolute; top: 1px; left: 1px; z-index: 2;border:none;" />
<div style="position: absolute;" id="filterDropdownDiv">
<select name="filterDropDown" id="filterDropDown" tabindex="1000"
onchange="DropDownTextToBox(this,'filterTextField');" style="position: absolute;
top: 0px; left: 0px; z-index: 1; width: 165px;">
<option value="-1" selected="selected" disabled="disabled">-- Select Column Name --</option>
</select>
<div class="container">
<div class="row">
<div class="col-xs-6 col-sm-6 col-md-6">
First Div
</div>
<div class="col-xs-6 col-sm-6 col-md-6">
Second Div
</div>
</div>
This does the trick.
One more for loop variant, looks cleaner to me than one with enumerate():
for idx in range(len(list)):
list[idx]=... # set a new value
# some other code which doesn't let you use a list comprehension
In Java, Dates are internally represented in UTC milliseconds since the epoch (so timezones are not taken into account, that's why you get the same results, as getTime()
gives you the mentioned milliseconds).
In your solution:
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
long gmtTime = cSchedStartCal.getTime().getTime();
long timezoneAlteredTime = gmtTime + TimeZone.getTimeZone("Asia/Calcutta").getRawOffset();
Calendar cSchedStartCal1 = Calendar.getInstance(TimeZone.getTimeZone("Asia/Calcutta"));
cSchedStartCal1.setTimeInMillis(timezoneAlteredTime);
you just add the offset from GMT to the specified timezone ("Asia/Calcutta" in your example) in milliseconds, so this should work fine.
Another possible solution would be to utilise the static fields of the Calendar
class:
//instantiates a calendar using the current time in the specified timezone
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
//change the timezone
cSchedStartCal.setTimeZone(TimeZone.getTimeZone("Asia/Calcutta"));
//get the current hour of the day in the new timezone
cSchedStartCal.get(Calendar.HOUR_OF_DAY);
Refer to stackoverflow.com/questions/7695859/ for a more in-depth explanation.
The claims that you have to mock it at the top of your file are false.
Mock a named ES Import:
// import the named module
import { useWalkthroughAnimations } from '../hooks/useWalkthroughAnimations';
// mock the file and its named export
jest.mock('../hooks/useWalkthroughAnimations', () => ({
useWalkthroughAnimations: jest.fn()
}));
// do whatever you need to do with your mocked function
useWalkthroughAnimations.mockReturnValue({ pageStyles, goToNextPage, page });
If you don't want to specify a repository you can add the following lines to the package.json
file:
"description":"",
"version":"0.0.1",
"private":true,
That worked for me.
By adding private
, you don't need to link to a repo.
For flutter projects you can also solve this issue
open your \android\app\build.gradle
you sould have the following:
android {
defaultConfig {
...
minSdkVersion 16
targetSdkVersion 28
}
}
If your minSdkVersion is set to 21 or higher, all you need to do is set multiDexEnabled to true in the defaultConfig. Like this
android {
defaultConfig {
...
minSdkVersion 16
targetSdkVersion 28
multiDexEnabled true
}
}
if your minSdkVersion is set to 20 or lower add multiDexEnabled true to the defaultConfig
And define the implementation
dependencies {
implementation 'com.android.support:multidex:1.0.3'// or 2.0.1
}
At the end you should have:
android {
defaultConfig {
...
minSdkVersion 16
targetSdkVersion 28
multiDexEnabled true // added this
}
}
dependencies {
implementation 'com.android.support:multidex:1.0.3'
}

Instructional graph algorithm implementations in java could be found here (by prof. Sedgewick et al.): http://algs4.cs.princeton.edu/code/
I was introduced to them while attending these exceptional algorithm courses on coursera (also taught by prof. Sedgewick):
If this is for showing a time of day to a user, then in at least 19 out of 20 you don’t need to care about kk
, HH
nor hh
. I suggest that you use something like this:
DateTimeFormatter defaultTimeFormatter
= DateTimeFormatter.ofLocalizedTime(FormatStyle.SHORT);
System.out.format("%s: %s%n",
Locale.getDefault(), LocalTime.MIN.format(defaultTimeFormatter));
The point is that it gives different output in different default locales. For example:
en_SS: 12:00 AM fr_BL: 00:00 ps_AF: 0:00 es_CO: 12:00 a.m.
The localized formats have been designed to conform with the expectations of different cultures. So they generally give the user a better experience and they save you of writing a format pattern string, which is always error-prone.
I furthermore suggest that you don’t use SimpleDateFormat
. That class is notoriously troublesome and fortunately long outdated. Instead I use java.time, the modern Java date and time API. It is so much nicer to work with.
Of course if you need to parse a string with a specified format, and also if you have a very specific formatting requirement, it’s good to use a format pattern string. There are actually four different pattern letters to choose from for hour (quoted from the documentation):
Symbol Meaning Presentation Examples
------ ------- ------------ -------
h clock-hour-of-am-pm (1-12) number 12
K hour-of-am-pm (0-11) number 0
k clock-hour-of-day (1-24) number 24
H hour-of-day (0-23) number 0
In practice H
and h
are used. As far as I know k
and K
are not (they may just have been included for the sake of completeness). But let’s just see them all in action:
DateTimeFormatter timeFormatter
= DateTimeFormatter.ofPattern("hh:mm a HH:mm kk:mm KK:mm a", Locale.ENGLISH);
System.out.println(LocalTime.of(0, 0).format(timeFormatter));
System.out.println(LocalTime.of(1, 15).format(timeFormatter));
System.out.println(LocalTime.of(11, 25).format(timeFormatter));
System.out.println(LocalTime.of(12, 35).format(timeFormatter));
System.out.println(LocalTime.of(13, 40).format(timeFormatter));
12:00 AM 00:00 24:00 00:00 AM 01:15 AM 01:15 01:15 01:15 AM 11:25 AM 11:25 11:25 11:25 AM 12:35 PM 12:35 12:35 00:35 PM 01:40 PM 13:40 13:40 01:40 PM
If you don’t want the leading zero, just specify one pattern letter, that is h
instead of hh
or H
instead of HH
. It will still accept two digits when parsing, and if a number to be printed is greater than 9, two digits will still be printed.
DateTimeFormatter
.A file is almost a list of lines. You can trivially use it in a for loop.
myFile= open( "SomeFile.txt", "r" )
for x in myFile:
print x
myFile.close()
Or, if you want an actual list of lines, simply create a list from the file.
myFile= open( "SomeFile.txt", "r" )
myLines = list( myFile )
myFile.close()
print len(myLines), myLines
You can't do someList[i]
to put a new item at the end of a list. You must do someList.append(i)
.
Also, never start a simple variable name with an uppercase letter. List
confuses folks who know Python.
Also, never use a built-in name as a variable. list
is an existing data type, and using it as a variable confuses folks who know Python.
By design, dictionaries are not sortable. If you need this capability in a dictionary, look at SortedDictionary instead.
'' encloses single char
, while "" encloses a String
.
Change
y = 'hello';
-->
y = "hello";
Like this:
function createJSON() {
jsonObj = [];
$("input[class=email]").each(function() {
var id = $(this).attr("title");
var email = $(this).val();
item = {}
item ["title"] = id;
item ["email"] = email;
jsonObj.push(item);
});
console.log(jsonObj);
}
Explanation
You are looking for an array of objects
. So, you create a blank array. Create an object for each input
by using 'title' and 'email' as keys. Then you add each of the objects to the array.
If you need a string, then do
jsonString = JSON.stringify(jsonObj);
Sample Output
[{"title":"QA","email":"a@b"},{"title":"PROD","email":"b@c"},{"title":"DEV","email":"c@d"}]
The typical answer to this question, unfortunately posted here already, is that one does the increment "before" remaining operations and the other does the increment "after" remaining operations. Though that intuitively gets the idea across, that statement is on the face of it completely wrong. The sequence of events in time is extremely well-defined in C#, and it is emphatically not the case that the prefix (++var) and postfix (var++) versions of ++ do things in a different order with respect to other operations.
It is unsurprising that you'll see a lot of wrong answers to this question. A great many "teach yourself C#" books also get it wrong. Also, the way C# does it is different than how C does it. Many people reason as though C# and C are the same language; they are not. The design of the increment and decrement operators in C# in my opinion avoids the design flaws of these operators in C.
There are two questions that must be answered to determine what exactly the operation of prefix and postfix ++ are in C#. The first question is what is the result? and the second question is when does the side effect of the increment take place?
It is not obvious what the answer to either question is, but it is actually quite simple once you see it. Let me spell out for you precisely what x++ and ++x do for a variable x.
For the prefix form (++x):
For the postfix form (x++):
Some things to notice:
First, the order of events in time is exactly the same in both cases. Again, it is absolutely not the case that the order of events in time changes between prefix and postfix. It is entirely false to say that the evaluation happens before other evaluations or after other evaluations. The evaluations happen in exactly the same order in both cases as you can see by steps 1 through 4 being identical. The only difference is the last step - whether the result is the value of the temporary, or the new, incremented value.
You can easily demonstrate this with a simple C# console app:
public class Application
{
public static int currentValue = 0;
public static void Main()
{
Console.WriteLine("Test 1: ++x");
(++currentValue).TestMethod();
Console.WriteLine("\nTest 2: x++");
(currentValue++).TestMethod();
Console.WriteLine("\nTest 3: ++x");
(++currentValue).TestMethod();
Console.ReadKey();
}
}
public static class ExtensionMethods
{
public static void TestMethod(this int passedInValue)
{
Console.WriteLine("Current:{0} Passed-in:{1}",
Application.currentValue,
passedInValue);
}
}
Here are the results...
Test 1: ++x
Current:1 Passed-in:1
Test 2: x++
Current:2 Passed-in:1
Test 3: ++x
Current:3 Passed-in:3
In the first test, you can see that both currentValue
and what was passed in to the TestMethod()
extension show the same value, as expected.
However, in the second case, people will try to tell you that the increment of currentValue
happens after the call to TestMethod()
, but as you can see from the results, it happens before the call as indicated by the 'Current:2' result.
In this case, first the value of currentValue
is stored in a temporary. Next, an incremented version of that value is stored back in currentValue
but without touching the temporary which still stores the original value. Finally that temporary is passed to TestMethod()
. If the increment happened after the call to TestMethod()
then it would write out the same, non-incremented value twice, but it does not.
It's important to note that the value returned from both the
currentValue++
and++currentValue
operations are based on the temporary and not the actual value stored in the variable at the time either operation exits.Recall in the order of operations above, the first two steps copy the then-current value of the variable into the temporary. That is what's used to calculate the return value; in the case of the prefix version, it's that temporary value incremented while in the case of the suffix version, it's that value directly/non-incremented. The variable itself is not read again after the initial storage into the temporary.
Put more simply, the postfix version returns the value that was read from the variable (i.e. the value of the temporary) while the prefix version returns the value that was written back to the variable (i.e. the incremented value of the temporary). Neither return the variable's value.
This is important to understand because the variable itself could be volatile and have changed on another thread which means the return value of those operations could differ from the current value stored in the variable.
It is surprisingly common for people to get very confused about precedence, associativity, and the order in which side effects are executed, I suspect mostly because it is so confusing in C. C# has been carefully designed to be less confusing in all these regards. For some additional analysis of these issues, including me further demonstrating the falsity of the idea that prefix and postfix operations "move stuff around in time" see:
https://ericlippert.com/2009/08/10/precedence-vs-order-redux/
which led to this SO question:
int[] arr={0}; int value = arr[arr[0]++]; Value = 1?
You might also be interested in my previous articles on the subject:
https://ericlippert.com/2008/05/23/precedence-vs-associativity-vs-order/
and
https://ericlippert.com/2007/08/14/c-and-the-pit-of-despair/
and an interesting case where C makes it hard to reason about correctness:
https://docs.microsoft.com/archive/blogs/ericlippert/bad-recursion-revisited
Also, we run into similar subtle issues when considering other operations that have side effects, such as chained simple assignments:
https://docs.microsoft.com/archive/blogs/ericlippert/chaining-simple-assignments-is-not-so-simple
And here's an interesting post on why the increment operators result in values in C# rather than in variables:
You can use the basename() function.
Yes. Use the attach
command. Check out this link for more information. Typing help attach
at a GDB console gives the following:
(gdb) help attach
Attach to a process or file outside of GDB. This command attaches to another target, of the same type as your last "
target
" command ("info files
" will show your target stack). The command may take as argument a process id, a process name (with an optional process-id as a suffix), or a device file. For a process id, you must have permission to send the process a signal, and it must have the same effective uid as the debugger. When using "attach
" to an existing process, the debugger finds the program running in the process, looking first in the current working directory, or (if not found there) using the source file search path (see the "directory
" command). You can also use the "file
" command to specify the program, and to load its symbol table.
NOTE: You may have difficulty attaching to a process due to improved security in the Linux kernel - for example attaching to the child of one shell from another.
You'll likely need to set /proc/sys/kernel/yama/ptrace_scope
depending on your requirements. Many systems now default to 1
or higher.
The sysctl settings (writable only with CAP_SYS_PTRACE) are:
0 - classic ptrace permissions: a process can PTRACE_ATTACH to any other
process running under the same uid, as long as it is dumpable (i.e.
did not transition uids, start privileged, or have called
prctl(PR_SET_DUMPABLE...) already). Similarly, PTRACE_TRACEME is
unchanged.
1 - restricted ptrace: a process must have a predefined relationship
with the inferior it wants to call PTRACE_ATTACH on. By default,
this relationship is that of only its descendants when the above
classic criteria is also met. To change the relationship, an
inferior can call prctl(PR_SET_PTRACER, debugger, ...) to declare
an allowed debugger PID to call PTRACE_ATTACH on the inferior.
Using PTRACE_TRACEME is unchanged.
2 - admin-only attach: only processes with CAP_SYS_PTRACE may use ptrace
with PTRACE_ATTACH, or through children calling PTRACE_TRACEME.
3 - no attach: no processes may use ptrace with PTRACE_ATTACH nor via
PTRACE_TRACEME. Once set, this sysctl value cannot be changed.
if we use same page to add/edit via submit button like below
<input type="hidden" value="<?echo $_GET['edit_id'];?>" name="edit_id">
then we should not use
isset($_POST['edit_id'])
bcoz edit_id
is set all the time whether it is add or edit page , instead we should use check below condition
!empty($_POST['edit_id'])
Here's some PowerShell code that should work. You can combine most of this into fewer lines, but I wanted to keep it clear and readable.
[string]$filePath = "C:\tempFile.zip";
[string]$directory = [System.IO.Path]::GetDirectoryName($filePath);
[string]$strippedFileName = [System.IO.Path]::GetFileNameWithoutExtension($filePath);
[string]$extension = [System.IO.Path]::GetExtension($filePath);
[string]$newFileName = $strippedFileName + [DateTime]::Now.ToString("yyyyMMdd-HHmmss") + $extension;
[string]$newFilePath = [System.IO.Path]::Combine($directory, $newFileName);
Move-Item -LiteralPath $filePath -Destination $newFilePath;
Candidate Key: The candidate key can be defined as minimal set of attribute which can uniquely identify a tuple is known as candidate key. For Example, STUD_NO in below STUDENT relation.
- The value of Candidate Key is unique and non-null for every tuple.
- There can be more than one candidate key in a relation. For Example, STUD_NO as well as STUD_PHONE both are candidate keys for relation STUDENT.
- The candidate key can be simple (having only one attribute) or composite as well. For Example, {STUD_NO, COURSE_NO} is a composite
candidate key for relation STUDENT_COURSE.
Super Key: The set of attributes which can uniquely identify a tuple is known as Super Key. For Example, STUD_NO, (STUD_NO, STUD_NAME) etc. Adding zero or more attributes to candidate key generates super key. A candidate key is a super key but vice versa is not true. Primary Key: There can be more than one candidate key in a relation out of which one can be chosen as primary key. For Example, STUD_NO as well as STUD_PHONE both are candidate keys for relation STUDENT but STUD_NO can be chosen as primary key (only one out of many candidate keys).
Alternate Key: The candidate key other than primary key is called as alternate key. For Example, STUD_NO as well as STUD_PHONE both are candidate keys for relation STUDENT but STUD_PHONE will be alternate key (only one out of many candidate keys).
Foreign Key: If an attribute can only take the values which are present as values of some other attribute, it will be foreign key to the attribute to which it refers. The relation which is being referenced is called referenced relation and corresponding attribute is called referenced attribute and the relation which refers to referenced relation is called referencing relation and corresponding attribute is called referencing attribute. Referenced attribute of referencing attribute should be primary key. For Example, STUD_NO in STUDENT_COURSE is a foreign key to STUD_NO in STUDENT relation.
Using getopt() function we can also read a parameter from the command line just. Pass a value with the php
running command:
php abc.php --name=xyz
$val = getopt(null, ["name:"]);
print_r($val); // Output: ['name' => 'xyz'];
apiclient
was the original name of the library.
At some point, it was switched over to be googleapiclient
.
If your code is running on Google App Engine, both should work.
If you are running the application yourself, with the google-api-python-client installed, both should work as well.
Although, if we take a look at the source code of the apiclient
package's __init__.py
module, we can see that the apiclient
module was simply kept around for backwards-compatibility.
Retain apiclient as an alias for googleapiclient.
So, you really should be using googleapiclient
in your code, since the apiclient
alias was just maintained as to not break legacy code.
# bad
from apiclient.discovery import build
# good
from googleapiclient.discovery import build
This is how I would do it (assuming I understand the question)
SELECT * FROM pieces ORDER BY price ASC LIMIT 1
If you are trying to select multiple rows where each of them may have the same price (which is the minimum) then @JohnWoo's answer should suffice.
Basically here we are just ordering the results by the price in ASCending order (increasing) and taking the first row of the result.

I opened the project org.eclipse.wst.common.project.facet.core.xml and first changed then removed line with web module tag. Cleaned project and launched on Tomcat each time but it still didn't run. Returned line (as was) and cleaned project. Opened Tomcat settings in Eclipse and manually added project to Tomcat startup (Right click + Add and Remove). Clicked on project and selected Run on server....and everything was fine.

I'm not 100% sure what your NonIntersect method is supposed to do (regarding set theory) - is it
B \ A (everything from B that does not occur in A)?
If yes, then you should be able to use the Except operation (B.Except(A)).
In my case this error was raised because table date column is not null-able
As below:
Create Table #TempTable(
...
ApprovalDate datatime not null.
...)
To avoid this error just make it null-able
Create Table #TempTable(
...
ApprovalDate datatime null.
...)

This might sound stupid and off topic but in my case I was using an external 4k Monitor with my MacBook Pro 13' (MacOS High Sierra, 2016) and I had the resolution set to the wrong scaled resolution. Switching to another scaled resolution where there was no "using a scaled resolution may affect performance" warning resolved my overall performance issues. In my case I had to increase the resolution to max.
So for me it was an overall performance problem which first surfaced with Android Studio, it was not an Android Studio specific problem.
EDIT 25.11.2017
As a result I had to increase font sizes in Android Studio:
and on my Mac in General. I followed some of these tips to get that done.
In case you have a.my-company.com

domain - it will be accepted and sent to both of the domains.
You need to define a single locale that you will use for the data stored in the database, the invariant culture is there for exactly this purpose.
When you display convert to the native type and then format for the user's culture.
E.g. to display:
string fromDb = "123.56";
string display = double.Parse(fromDb, CultureInfo.InvariantCulture).ToString(userCulture);
to store:
string fromUser = "132,56";
double value;
// Probably want to use a more specific NumberStyles selection here.
if (!double.TryParse(fromUser, NumberStyles.Any, userCulture, out value)) {
// Error...
}
string forDB = value.ToString(CultureInfo.InvariantCulture);
PS. It, almost, goes without saying that using a column with a datatype that matches the data would be even better (but sometimes legacy applies).

Here's a simple little utility class that you can use to convert local date times from zone to zone, including a utility method directly to convert a local date time from the current zone to UTC (with main method so you can run it and see the results of a simple test):
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.ZoneOffset;
import java.time.ZonedDateTime;
public final class DateTimeUtil {
private DateTimeUtil() {
super();
}
public static void main(final String... args) {
final LocalDateTime now = LocalDateTime.now();
final LocalDateTime utc = DateTimeUtil.toUtc(now);
System.out.println("Now: " + now);
System.out.println("UTC: " + utc);
}
public static LocalDateTime toZone(final LocalDateTime time, final ZoneId fromZone, final ZoneId toZone) {
final ZonedDateTime zonedtime = time.atZone(fromZone);
final ZonedDateTime converted = zonedtime.withZoneSameInstant(toZone);
return converted.toLocalDateTime();
}
public static LocalDateTime toZone(final LocalDateTime time, final ZoneId toZone) {
return DateTimeUtil.toZone(time, ZoneId.systemDefault(), toZone);
}
public static LocalDateTime toUtc(final LocalDateTime time, final ZoneId fromZone) {
return DateTimeUtil.toZone(time, fromZone, ZoneOffset.UTC);
}
public static LocalDateTime toUtc(final LocalDateTime time) {
return DateTimeUtil.toUtc(time, ZoneId.systemDefault());
}
}
Building on rcar's answer, you have to make sure a substring of the target isn't found.

if errorlevel 1 echo %X% is in PATH
Be sure the font is the same for all browsers. If it is the same font, then the problem has no solution using cross-browser CSS.
Because every browser has its own font rendering engine, they are all different. They can also differ in later versions, or across different OS's.
UPDATE: For those who do not understand the browser and OS font rendering differences, read this and this.
However, the difference is not even noticeable by most people, and users accept that. Forget pixel-perfect cross-browser design, unless you are:
UPDATE: I checked the example page. Tuning the kerning by text-rendering should help:

So, this is an old post, however I think I can contribute something to it.
You can always do something like this:
package com.dyna.test;
import java.io.File;
import java.lang.reflect.Constructor;
public class DynamicClass{
@SuppressWarnings("unchecked")
public Object castDynamicClass(String className, String value){
Class<?> dynamicClass;
try
{
//We get the actual .class object associated with the specified name
dynamicClass = Class.forName(className);
/* We get the constructor that received only
a String as a parameter, since the value to be used is a String, but we could
easily change this to be "dynamic" as well, getting the Constructor signature from
the same datasource we get the values from */
Constructor<?> cons =
(Constructor<?>) dynamicClass.getConstructor(new Class<?>[]{String.class});
/*We generate our object, without knowing until runtime
what type it will be, and we place it in an Object as
any Java object extends the Object class) */
Object object = (Object) cons.newInstance(new Object[]{value});
return object;
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
public static void main(String[] args)
{
DynamicClass dynaClass = new DynamicClass();
/*
We specify the type of class that should be used to represent
the value "3.0", in this case a Double. Both these parameters
you can get from a file, or a network stream for example. */
System.out.println(dynaClass.castDynamicClass("java.lang.Double", "3.0"));
/*
We specify a different value and type, and it will work as
expected, printing 3.0 in the above case and the test path in the one below, as the Double.toString() and
File.toString() would do. */
System.out.println(dynaClass.castDynamicClass("java.io.File", "C:\\testpath"));
}
Of course, this is not really dynamic casting, as in other languages (Python for example), because java is a statically typed lang. However, this can solve some fringe cases where you actually need to load some data in different ways, depending on some identifier. Also, the part where you get a constructor with a String parameter could be probably made more flexible, by having that parameter passed from the same data source. I.e. from a file, you get the constructor signature you want to use, and the list of values to be used, that way you pair up, say, the first parameter is a String, with the first object, casting it as a String, next object is an Integer, etc, but somehwere along the execution of your program, you get now a File object first, then a Double, etc.
In this way, you can account for those cases, and make a somewhat "dynamic" casting on-the-fly.
Hope this helps anyone as this keeps turning up in Google searches.
I was getting the same error, then updated my connection string as below,
<add name="EmployeeContext" connectionString="data source=*****;initial catalog=EmployeeDB;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework" providerName="System.Data.SqlClient" />
Try this it will solve your issue.
If you need to specify the exact charactor length, we have to avoid values with 0 in-front.
Final String representation must have that exact character length.
String GenerateRandomNumber(int charLength) {
return String.valueOf(charLength < 1 ? 0 : new Random()
.nextInt((9 * (int) Math.pow(10, charLength - 1)) - 1)
+ (int) Math.pow(10, charLength - 1));

Stop using the TEXT
data type in SQL Server!
It's been deprecated since the 2005 version. Use VARCHAR(MAX)
instead, if you need more than 8000 characters.
The TEXT
data type doesn't support the normal string functions, while VARCHAR(MAX)
does - your statement would work just fine, if you'd be using just VARCHAR types.
Windows 10 build 15063 "Creators Update" natively supports SVG images (though with some gotchas) to UWP/UAP applications targeting Windows 10.
If your application is a WPF app rather than a UWP/UAP, you can still use this API (after jumping through quite a number of hoops): Windows 10 build 17763 "October 2018 Update" introduced the concept of XAML islands (as a "preview" technology but I believe allowed in the app store; in all cases, with Windows 10 build 18362 "May 2019 Update" XAML islands are no longer a preview feature and are fully supported) allowing you to use UWP APIs and controls in your WPF applications.
You need to first add the references to the WinRT APIs, and to use certain Windows 10 APIs that interact with user data or the system (e.g. loading images from disk in a Windows 10 UWP webview or using the toast notification API to show toasts), you also need to associate your WPF application with a package identity, as shown here (immensely easier in Visual Studio 2019). This shouldn't be necessary to use the Windows.UI.Xaml.Media.Imaging.SvgImageSource
class, though.
Usage (if you're on UWP or you've followed the directions above and added XAML island support under WPF) is as simple as setting the Source
for an <Image />
to the path to the SVG. That is equivalent to using SvgImageSource
, as follows:
<Image>
<Image.Source>
<SvgImageSource UriSource="Assets/svg/icon.svg" />
</Image.Source>
</Image>
However, SVG images loaded in this way (via XAML) may load jagged/aliased. One workaround is to specify a RasterizePixelHeight
or RasterizePixelWidth
value that is double+ your actual height/width:
<SvgImageSource RasterizePixelHeight="300" RasterizePixelWidth="300" UriSource="Assets/svg/icon.svg" /> <!-- presuming actual height or width is under 150 -->
This can be worked around dynamically by creating a new SvgImageSource
in the ImageOpened
event for the base image:
var svgSource = new SvgImageSource(new Uri("ms-appx://" + Icon));
PrayerIcon.ImageOpened += (s, e) =>
{
var newSource = new SvgImageSource(svgSource.UriSource);
newSource.RasterizePixelHeight = PrayerIcon.DesiredSize.Height * 2;
newSource.RasterizePixelWidth = PrayerIcon.DesiredSize.Width * 2;
PrayerIcon2.Source = newSource;
};
PrayerIcon.Source = svgSource;
The aliasing may be hard to see on non high-dpi screens, but here's an attempt to illustrate it.
This is the result of the code above: an Image
that uses the initial SvgImageSource
, and a second Image
below it that uses the SvgImageSource created in the ImageOpened
event:
This is a blown up view of the top image:
Whereas this is a blown-up view of the bottom (antialiased, correct) image:
(you'll need to open the images in a new tab and view at full size to appreciate the difference)

parameter, which will allow the spawned subprocess to be detached from the Python process itself and continue running even after Python exits.

In order to reduce crc32 to taking the reminder you need to:
In code this is:
func CRC32 (file []byte) uint32 {
for i , v := range(file) {
file[i] = bits.Reverse8(v)
}
for i := 0; i < 4; i++ {
file[i] ^= 0xFF
}
// Add padding
file = append(file, []byte{0, 0, 0, 0}...)
newReminder := bits.Reverse32(reminderIEEE(file))
return newReminder ^ 0xFFFFFFFF
}
where reminderIEEE is the pure reminder on GF(2)[x]
You've got to override your Canvas's paint(Graphics g)
method and perform your drawing there. See the paint() documentation.
As it states, the default operation is to clear the canvas, so your call to the canvas' graphics object doesn't perform as you would expect.
import platform
platform.architecture()
From the Python docs:
Queries the given executable (defaults to the Python interpreter binary) for various architecture information.
Returns a tuple (bits, linkage) which contain information about the bit architecture and the linkage format used for the executable. Both values are returned as strings.
Yes changing the error_to debug level as Emmanuel Joubaud suggested worked out (edit /etc/nginx/sites-enabled/default ):
error_log /var/log/nginx/error.log debug;
Then after restaring nginx I got in the error log with my Python application using uwsgi:

Then I took a look to my uwsgi log and found out that:
Invalid HTTP_HOST header: 'www.mysite.local'. You may need to add u'www.mysite.local' to ALLOWED_HOSTS.

And adding www.mysite.local to the settings.py ALLOWED_HOSTS fixed the issue :)
ALLOWED_HOSTS = ['www.mysite.local']

You could use lvh.me:9000
to access your AngularJS app, (lvh.me
just points to 127.0.0.1) and then specify a different endpoint if lvh.me
is the host:
app.service("Configuration", function() {
if (window.location.host.match(/lvh\.me/)) {
return this.API = 'http://localhost\\:7080/myapi/';
} else {
return this.API = 'http://localhost\\:8099/hisapi/';
}
});
And then inject the Configuration service and use Configuration.API
wherever you need to access the API:
$resource(Configuration.API + '/endpoint/:id', {
id: '@id'
});
A tad clunky, but works fine for me, albeit in a slightly different situation (API endpoints differ in production and development).
Overall
SELECT
COUNT(DISTINCT `site_id`) as distinct_sites
FROM `cp_visits`
WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
Or per site
SELECT
`site_id` as site,
COUNT(DISTINCT `user_id`) as distinct_users_per_site
FROM `cp_visits`
WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
GROUP BY `site_id`
Having the time
column in the result doesn't make sense - since you are aggregating the rows, showing one particular time
is irrelevant, unless it is the min
or max
you are after.
You could use a string stream and read the elements into the vector.
Here are many different examples...
A copy of one of the examples:
std::vector<std::string> split(const std::string& s, char seperator)
{
std::vector<std::string> output;
std::string::size_type prev_pos = 0, pos = 0;
while((pos = s.find(seperator, pos)) != std::string::npos)
{
std::string substring( s.substr(prev_pos, pos-prev_pos) );
output.push_back(substring);
prev_pos = ++pos;
}
output.push_back(s.substr(prev_pos, pos-prev_pos)); // Last word
return output;
}
Here is an example of how to achieve what you need:
<canvas id="myCanvas" width="578" height="200"></canvas>
<script>
var canvas = document.getElementById('myCanvas');
var context = canvas.getContext('2d');
// begin custom shape
context.beginPath();
context.moveTo(170, 80);
context.bezierCurveTo(130, 100, 130, 150, 230, 150);
context.bezierCurveTo(250, 180, 320, 180, 340, 150);
context.bezierCurveTo(420, 150, 420, 120, 390, 100);
context.bezierCurveTo(430, 40, 370, 30, 340, 50);
context.bezierCurveTo(320, 5, 250, 20, 250, 50);
context.bezierCurveTo(200, 5, 150, 20, 170, 80);
// complete custom shape
context.closePath();
context.lineWidth = 5;
context.fillStyle = '#8ED6FF';
context.fill();
context.strokeStyle = 'blue';
context.stroke();
</script>

Something like this should do it:
for element in list_:
sys.stdout.write(str(element))
You generally shouldn't use e.g. const int
in a header file, if it's included in several source files. That is because then the variables will be defined once per source file (translation units technically speaking) because global const
variables are implicitly static, taking up more memory than required.
You should instead have a special source file, Constants.cpp
that actually defines the variables, and then have the variables declared as extern
in the header file.
Something like this header file:
// Protect against multiple inclusions in the same source file
#ifndef CONSTANTS_H
#define CONSTANTS_H
extern const int CONSTANT_1;
#endif
And this in a source file:
const int CONSTANT_1 = 123;
While that particular idiom is common, even more common is for people to use =
when they mean ==
. The convention when you really mean the =
is to use an extra layer of parentheses:
while ((list = list->next)) { // yes, it's an assignment
Can't you use JOIN like this one?
SELECT
a.x , b.y, b.z
FROM a
LEFT OUTER JOIN b ON b.v = a.v

You can write
i = 5 + tup()[0]
Tuples can be indexed just like lists.
The main difference between tuples and lists is that tuples are immutable - you can't set the elements of a tuple to different values, or add or remove elements like you can from a list. But other than that, in most situations, they work pretty much the same.
If you're running a *nix system, also consider mytop.
To limit the results to one database, press "d" when it's running then type in the database name.
I don't know how to delete all at once, but you can use ipcs
to list resources, and then use loop and delete with ipcrm
. This should work, but it needs a little work. I remember that I made it work once in class.
Because %
is only defined for integer types. That's the modulus operator.
5.6.2 of the standard:
The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]
As Oli pointed out, you can use fmod()
. Don't forget to include math.h
.
PROBLEM RESOLVED
In my case the problem was that I do the ajax call (with $.ajax, $.get or $.getJSON methods from jQuery) with full path in the url param:
But the correct way is to pass the value of url as:
url: "site/cgi-bin/serverApp.php"
Some browser don't conflict and make no distiction between one text or another, but in Firefox 3.6 for Mac OS take this full path as "cross site scripting"... another thing, in the same browser there is a distinction between:
http://mydomain.com/site/index.html
And put
http://www.mydomain.com/site/index.html
In fact it is the correct point view, but most implementations make no distinction, so the solution was to remove all the text that specify the full path to the script in the methods that do the ajax request AND.... remove any BASE tag in the index.html file
base href="http://mydomain.com/" <--- bad idea, remove it!
If you don't remove it, this version of browser for this system may take your ajax request like if it is a cross site request!
I have the same problem but only on the Mac OS machine. The problem is that Firefox treat the ajax response as an "cross site" call, in any other machine/browser it works fine. I didn't found any help about this (I think that is a firefox implementation issue), but I'm going to prove the next code at the server side:
header('Content-type: application/json');
to ensure that browser get the data as "json data" ...
All the current answers clobber the non-writing permissions: they make the file readable-but-not-executable for everybody. Granted, this is because the initial question asked for 444
permissions -- but we can do better!
Here's a solution that leaves all the individual "read" and "execute" bits untouched. I wrote verbose code to make it easy to understand; you can make it more terse if you like.
import os
import stat
def remove_write_permissions(path):
"""Remove write permissions from this path, while keeping all other permissions intact.
Params:
path: The path whose permissions to alter.
"""
NO_USER_WRITING = ~stat.S_IWUSR
NO_GROUP_WRITING = ~stat.S_IWGRP
NO_OTHER_WRITING = ~stat.S_IWOTH
NO_WRITING = NO_USER_WRITING & NO_GROUP_WRITING & NO_OTHER_WRITING
current_permissions = stat.S_IMODE(os.lstat(path).st_mode)
os.chmod(path, current_permissions & NO_WRITING)
Why does this work?
As John La Rooy pointed out,stat.S_IWUSR
basically means "the bitmask for the user's write permissions". We want to set the corresponding permission bit to 0. To do that, we need the exact opposite bitmask (i.e., one with a 0 in that location, and 1's everywhere else). The ~
operator, which flips all the bits, gives us exactly that. If we apply this to any variable via the "bitwise and" operator (&
), it will zero out the corresponding bit.
We need to repeat this logic with the "group" and "other" permission bits, too. Here we can save some time by just &
'ing them all together (forming the NO_WRITING
bit constant).
The last step is to get the current file's permissions, and actually perform the bitwise-and operation.
Based on the answer by @peteb, but using Promises
and Async/Await
:
const AWS = require('aws-sdk');
const s3 = new AWS.S3();
async function getObject (bucket, objectKey) {
try {
const params = {
Bucket: bucket,
Key: objectKey
}
const data = await s3.getObject(params).promise();
return data.Body.toString('utf-8');
} catch (e) {
throw new Error(`Could not retrieve file from S3: ${e.message}`)
}
}
// To retrieve you need to use `await getObject()` or `getObject().then()`
getObject('my-bucket', 'path/to/the/object.txt').then(...);
rawLapsData
continues to point to the same array, even if you modify the contents of the array (e.g., add items, remove items, change an item).
During change detection, when Angular checks components' input properties for change, it uses (essentially) ===
for dirty checking. For arrays, this means the array references (only) are dirty checked. Since the rawLapsData
array reference isn't changing, ngOnChanges()
will not be called.
I can think of two possible solutions:
Implement ngDoCheck()
and perform your own change detection logic to determine if the array contents have changed. (The Lifecycle Hooks doc has an example.)
Assign a new array to rawLapsData
whenever you make any changes to the array contents. Then ngOnChanges()
will be called because the array (reference) will appear as a change.
In your answer, you came up with another solution.
Repeating some comments here on the OP:
I still don't see how
laps
can pick up on the change (surely it must be using something equivalent tongOnChanges()
itself?) whilemap
can't.
laps
component your code/template loops over each entry in the lapsData
array, and displays the contents, so there are Angular bindings on each piece of data that is displayed.===
checking), it still (by default) dirty checks all of the template bindings. When any of those change, Angular will update the DOM. That's what you are seeing.maps
component likely doesn't have any bindings in its template to its lapsData
input property, right? That would explain the difference.Note that lapsData
in both components and rawLapsData
in the parent component all point to the same/one array. So even though Angular doesn't notice any (reference) changes to the lapsData
input properties, the components "get"/see any array contents changes because they all share/reference that one array. We don't need Angular to propagate these changes, like we would with a primitive type (string, number, boolean). But with a primitive type, any change to the value would always trigger ngOnChanges()
– which is something you exploit in your answer/solution.
As you probably figured out by now object input properties have the same behavior as array input properties.
I use setTimeout.
Apparently the difference is setTimeout calls the method once, setInterval calls it repeatdly.
Here is a good article explaining the difference: Tutorial: JavaScript timers with setTimeout and setInterval
Byte is not a standard type in C/C++, so it is represented by char
.
An advantage of this is that you can treat a basic_string
as a byte array allowing for safe storage and function passing. This will help you avoid the memory leaks and segmentation faults you might encounter when using the various forms of char[]
and char*
.
For example, this creates a string as a byte array of null values:
typedef basic_string<unsigned char> u_string;
u_string bytes = u_string(16,'\0');
This allows for standard bitwise operations with other char
values, including those stored in other string
variables. For example, to XOR the char
values of another u_string
across bytes
:
u_string otherBytes = "some more chars, which are just bytes";
for(int i = 0; i < otherBytes.length(); i++)
bytes[i%16] ^= (int)otherBytes[i];
Copy the global variable to a variable in the scope in your controller.
function MyCtrl($scope) {
$scope.variable1 = variable1;
}
Then you can just access it like you tried. But note that this variable will not change when you change the global variable. If you need that, you could instead use a global object and "copy" that. As it will be "copied" by reference, it will be the same object and thus changes will be applied (but remember that doing stuff outside of AngularJS will require you to do $scope.$apply anway).
But maybe it would be worthwhile if you would describe what you actually try to achieve. Because using a global variable like this is almost never a good idea and there is probably a better way to get to your intended result.
Scott Guthrie has made a post on how to change Visual Studio's default browser:
1) Right click on a .aspx page in your solution explorer
2) Select the "browse with" context menu option
3) In the dialog you can select or add a browser. If you want Firefox in the list, click "add" and point to the firefox.exe filename
4) Click the "Set as Default" button to make this the default browser when you run any page on the site.
I however dislike the fact that this isn't as straightforward as it should be.
When it comes to inserting a picture, r2evans's suggestion of ![Caption for the picture.](/path/to/image.png)

is a more portable alternative
that will generate, on your behalf, the markdown that is most appropriate to the output format that you are generating.
