Wrap your ListView in an Expanded widget
Expanded(child:MyListView())
I'm currently taking some legacy codebases and introducing minimal TypeScript changes to see if it helps our team. Depending on how strict you want to be with TypeScript, this may or may not be an option for you.
The most helpful way for us to get started was to extend our tsconfig.json
file with this property:
// tsconfig.json excerpt:
{
...
"compilerOptions": {
...
"allowJs": true,
...
}
...
}
This change lets our JS files that have JSDoc type hints get compiled. Also our IDEs (JetBrains IDEs and VS Code) can provide code-completion and Intellisense.

What about something like this.
<div id="movie_item">
<div class="movie_item_poster">
<img src="..." style="max-width: 100%; max-height: 100%;">
</div>
<div id="movie_item_content">
<div class="movie_item_content_year">year</div>
<div class="movie_item_content_title">title</div>
<div class="movie_item_content_plot">plot</div>
</div>
<div class="movie_item_toolbar">
Lorem Ipsum...
</div>
</div>
You don't have to float both movie_item_poster
AND movie_item_content
. Just float one of them...
#movie_item {
position: relative;
margin-top: 10px;
height: 175px;
}
.movie_item_poster {
float: left;
height: 150px;
width: 100px;
}
.movie_item_content {
position: relative;
}
.movie_item_content_title {
}
.movie_item_content_year {
float: right;
}
.movie_item_content_plot {
}
.movie_item_toolbar {
clear: both;
vertical-align: bottom;
width: 100%;
height: 25px;
}
When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.
SQL does not do that. The order of the tuples in the table are not ordered by insertion date. A lot of people include a column that stores that date of insertion in order to get around this issue.
here is another solution...
System.IO.Stream st = new System.IO.StreamReader (picturePath).BaseStream;
byte[] buffer = new byte[4096];
System.IO.MemoryStream m = new System.IO.MemoryStream ();
while (st.Read (buffer,0,buffer.Length) > 0) {
m.Write (buffer, 0, buffer.Length);
}
imgView.Tag = m.ToArray ();
st.Close ();
m.Close ();
hope it helps!
You can use the file Object to get the length of the file to initialize your array:
int length = Long.valueOf(file.length()).intValue();
byte[] byteArray = new byte[length];

public UIImage CreateImageFromColor()
{
var imageSize = new CGSize(30, 30);
var imageSizeRectF = new CGRect(0, 0, 30, 30);
UIGraphics.BeginImageContextWithOptions(imageSize, false, 0);
var context = UIGraphics.GetCurrentContext();
var red = new CGColor(255, 0, 0);
context.SetFillColor(red);
context.FillRect(imageSizeRectF);
var image = UIGraphics.GetImageFromCurrentImageContext();
UIGraphics.EndImageContext();
return image;
}
All Swift 3 answers did not worked for me so I have translated the most accepted answer:
extension UIImage {
class func imageWithView(view: UIView) -> UIImage {
UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.isOpaque, 0.0)
view.layer.render(in: UIGraphicsGetCurrentContext()!)
let img: UIImage? = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return img!
}
}
I used this single line of code to create a new UIImage which is scaled. Set the scale and orientation params to achieve what you want. The first line of code just grabs the image.
// grab the original image
UIImage *originalImage = [UIImage imageNamed:@"myImage.png"];
// scaling set to 2.0 makes the image 1/2 the size.
UIImage *scaledImage =
[UIImage imageWithCGImage:[originalImage CGImage]
scale:(originalImage.scale * 2.0)
orientation:(originalImage.imageOrientation)];
I found a really easy solution: add to the mail command the modifier -aContent-Type:text/html.
In your case would be:
mail -aContent-Type:text/html -s "Built notification" [email protected] < /var/www/report.csv
-(UIImage *)convertViewToImage
{
UIGraphicsBeginImageContext(self.bounds.size);
[self drawViewHierarchyInRect:self.bounds afterScreenUpdates:YES];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
Use the casting operator (string)$yourObject;
Your class's constructor method should be called __construct()
, not __constructor()
:
public function __construct(EntityManager $entityManager)
{
$this->em = $entityManager;
}
All the above answers are generating an issue which is that col[0].column is returning number while worksheet.column_dimensions[column] accepts only character such as 'A', 'B', 'C' in place of column. I've modified @Virako's code and it is working fine now.
import re
import openpyxl
..
for col in _ws.columns:
max_lenght = 0
print(col[0])
col_name = re.findall('\w\d', str(col[0]))
col_name = col_name[0]
col_name = re.findall('\w', str(col_name))[0]
print(col_name)
for cell in col:
try:
if len(str(cell.value)) > max_lenght:
max_lenght = len(cell.value)
except:
pass
adjusted_width = (max_lenght+2)
_ws.column_dimensions[col_name].width = adjusted_width
If you are sure that you selected the Generic iOS device
and still can't see the option, then you simply have to restart Xcode.
This was the missing solution for me as a cordova developer with Xcode 11.2
If you are checking against a lot of intervals, I suggest using an interval tree.
foreach($linksArray as $key => $link)
{
if($link === '')
{
unset($linksArray[$key]);
}
}
print_r($linksArray);
While this isn't exactly specific to jQuery selectors/objects, in FireFox Quantum 58.x, you can find event handlers on an element using the Dev tools:
By the way it is written, clean rule is invoked only if it is explicitly called:
make clean
I think it is better, than make clean every time. If you want to do this by your way, try this:
CXX = g++ -O2 -Wall all: clean code1 code2 code1: code1.cc utilities.cc $(CXX) $^ -o $@ code2: code2.cc utilities.cc $(CXX) $^ -o $@ clean: rm ... echo Clean done
Interfaces just provide a list of things a class will provide, not an actual implementation of those things, which is what your static item is.
If you want statics, use an abstract class and inherit it, otherwise, remove the static.
Hope that helps!
tar -cvzf filename.tar.gz directory_to_compress/
Most tar
commands have a z
option to create a gzip
ed version.
Though seems to me the question is how to circumvent Google. I'm not sure if renaming your output file would fool Google, but you could try. I.e.,
tar -cvzf filename.bla directory_to_compress/
and then send the filename.bla
- contents will would be a zipped tar, so at the other end it could be retrieved as usual.
As provided in chosen explanation, git reset is good. But nowadays we often use sub-modules: repositories inside repositories. For example, you if you use ZF3 and jQuery in your project you most probably want them to be cloned from their original repositories. In such case git reset is not enough. We need to update submodules to that exact version that are defined in our repository:
git checkout master
git fetch origin master
git reset --hard origin/master
git pull
git submodule foreach git submodule update
git status
it is the same as you will come (cd) recursively to the working directory of each sub-module and will run:
git submodule update
And it's very different from
git checkout master
git pull
because sub-modules point not to branch but to the commit.
In that cases when you manually checkout some branch for 1 or more submodules you can run
git submodule foreach git pull
input type Button
<input type="button" Id="update" value="Update">
I've successfully posted a form with AJAX in perl. After posting the form, controller returns a JSON response as below
$(function() {
$('#Search').click(function() {
var query = $('#query').val();
var update = $('#update').val();
$.ajax({
type: 'POST',
url: '/Products/Search/',
data: {
'insert': update,
'query': address,
},
success: function(res) {
$('#ProductList').empty('');
console.log(res);
json = JSON.parse(res);
for (var i in json) {
var row = $('<tr>');
row.append($('<td id=' + json[i].Id + '>').html(json[i].Id));
row.append($('<td id=' + json[i].Name + '>').html(json[i].Name));
$('</tr>');
$('#ProductList').append(row);
}
},
error: function() {
alert("did not work");
location.reload(true);
}
});
});
});
There are many ways of doing.
1) Use symbols. It won't give you any type safety, though, aside from not accepting non-symbols where a symbol is expected. I'm only mentioning it here for completeness. Here's an example of usage:
def update(what: Symbol, where: Int, newValue: Array[Int]): MatrixInt =
what match {
case 'row => replaceRow(where, newValue)
case 'col | 'column => replaceCol(where, newValue)
case _ => throw new IllegalArgumentException
}
// At REPL:
scala> val a = unitMatrixInt(3)
a: teste7.MatrixInt =
/ 1 0 0 \
| 0 1 0 |
\ 0 0 1 /
scala> a('row, 1) = a.row(0)
res41: teste7.MatrixInt =
/ 1 0 0 \
| 1 0 0 |
\ 0 0 1 /
scala> a('column, 2) = a.row(0)
res42: teste7.MatrixInt =
/ 1 0 1 \
| 0 1 0 |
\ 0 0 0 /
2) Using class Enumeration
:
object Dimension extends Enumeration {
type Dimension = Value
val Row, Column = Value
}
or, if you need to serialize or display it:
object Dimension extends Enumeration("Row", "Column") {
type Dimension = Value
val Row, Column = Value
}
This can be used like this:
def update(what: Dimension, where: Int, newValue: Array[Int]): MatrixInt =
what match {
case Row => replaceRow(where, newValue)
case Column => replaceCol(where, newValue)
}
// At REPL:
scala> a(Row, 2) = a.row(1)
<console>:13: error: not found: value Row
a(Row, 2) = a.row(1)
^
scala> a(Dimension.Row, 2) = a.row(1)
res1: teste.MatrixInt =
/ 1 0 0 \
| 0 1 0 |
\ 0 1 0 /
scala> import Dimension._
import Dimension._
scala> a(Row, 2) = a.row(1)
res2: teste.MatrixInt =
/ 1 0 0 \
| 0 1 0 |
\ 0 1 0 /
Unfortunately, it doesn't ensure that all matches are accounted for. If I forgot to put Row or Column in the match, the Scala compiler wouldn't have warned me. So it gives me some type safety, but not as much as can be gained.
3) Case objects:
sealed abstract class Dimension
case object Row extends Dimension
case object Column extends Dimension
Now, if I leave out a case on a match
, the compiler will warn me:
MatrixInt.scala:70: warning: match is not exhaustive!
missing combination Column
what match {
^
one warning found
It's used pretty much the same way, and doesn't even need an import
:
scala> val a = unitMatrixInt(3)
a: teste3.MatrixInt =
/ 1 0 0 \
| 0 1 0 |
\ 0 0 1 /
scala> a(Row,2) = a.row(0)
res15: teste3.MatrixInt =
/ 1 0 0 \
| 0 1 0 |
\ 1 0 0 /
You might wonder, then, why ever use an Enumeration instead of case objects. As a matter of fact, case objects do have advantages many times, such as here. The Enumeration class, though, has many Collection methods, such as elements (iterator on Scala 2.8), which returns an Iterator, map, flatMap, filter, etc.
This answer is essentially a selected parts from this article in my blog.
You can define a a click function and then set the onclick
attribute for the element.
function imageClick(url) {
window.location = url;
}
<img src="../images/bottle.jpg" alt="bottle" class="thumbnails" onclick="imageClick('../images/bottle.html')" />
This approach lets you get rid of the surrounding <a>
element. If you want to keep it, then define the onclick
attribute on <a>
instead of on <img>
.
another way is to use the range method
foo = [1,2,3,4,5,6]
bar = [10,20,30,40,50,60]
a = foo[0...3]
b = bar[3...6]
print a + b
=> [1, 2, 3, 40, 50 , 60]
Woff is a compressed (zipped) form of the TrueType - OpenType font. It is small and can be delivered over the network like a graphic file. Most importantly, this way the font is preserved completely including rendering rule tables that very few people care about because they use only Latin script.
Take a look at [dead URL removed]. The font you see is an experimental web delivered smartfont (woff) that has thousands of combined characters making complex shapes. The underlying text is simple Latin code of romanized Singhala. (Copy and paste to Notepad and see).
Only woff can do this because nobody has this font and yet it is seen anywhere (Mac, Win, Linux and even on smartphones by all browsers except by IE. IE does not have full support for Open Types).
I met a similar problem.
The solution is to use git log
to look up which version of the local commit is different from the remote. (E.g. the version is 3c74a11530697214cbcc4b7b98bf7a65952a34ec
).
Then use git reset --hard 3c74a11530697214cbcc4b7b98bf7a65952a34ec
to revert the change.
When you modifiy it a little, it works regardless which dateFormat you have set.
$("#datepicker").datepicker({
dateFormat: "@", // Unix timestamp
onSelect: function(dateText, inst){
addOrRemoveDate(dateText);
},
beforeShowDay: function(date){
var gotDate = $.inArray($.datepicker.formatDate($(this).datepicker('option', 'dateFormat'), date), dates);
if (gotDate >= 0) {
return [false,"ui-state-highlight", "Event Name"];
}
return [true, ""];
}
});
private void CopyDataTable(DataTable table){
// Create an object variable for the copy.
DataTable copyDataTable;
copyDataTable = table.Copy();
// Insert code to work with the copy.
}
I came across this question when I was trying to learn how to pass data from one View Controller to another. I need something visual to help me learn though, so this answer is a supplement to the others already here. It is a little more general than the original question but it can be adapted to work.
This basic example works like this:
The idea is to pass a string from the text field in the First View Controller to the label in the Second View Controller.
import UIKit
class FirstViewController: UIViewController {
@IBOutlet weak var textField: UITextField!
// This function is called before the segue
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// get a reference to the second view controller
let secondViewController = segue.destinationViewController as! SecondViewController
// set a variable in the second view controller with the String to pass
secondViewController.receivedString = textField.text!
}
}
import UIKit
class SecondViewController: UIViewController {
@IBOutlet weak var label: UILabel!
// This variable will hold the data being passed from the First View Controller
var receivedString = ""
override func viewDidLoad() {
super.viewDidLoad()
// Used the text from the First View Controller to set the label
label.text = receivedString
}
}
UITextField
and the UILabel

JDK version 9:
sudo apt install openjdk-9-jre
JDK version 8:
sudo apt install openjdk-8-jre
Open Jenkins configuration file:

If you are planning to install from source, then albertov's answer will help. But unless there is a reason, don't, just install it from the repository.
It may come when the API(you are consuming) is not sending the corresponding JSON. You may experience the response as 404 page or something like HTML/XML response.
The ls
command in conjunction with -l
(long listing) option returns attributes information about files and directories.
In particular the first character of ls -l
output it is usually a d
or a -
(dash). In case of a d
the one listed is a directory for sure.
The following command in just one line will tell you if the given ISDIR
variable contains a path to a directory or not:
[[ $(ls -ld "$ISDIR" | cut -c1) == 'd' ]] &&
echo "YES, $ISDIR is a directory." ||
echo "Sorry, $ISDIR is not a directory"
Practical usage:
[claudio@nowhere ~]$ ISDIR="$HOME/Music"
[claudio@nowhere ~]$ ls -ld "$ISDIR"
drwxr-xr-x. 2 claudio claudio 4096 Aug 23 00:02 /home/claudio/Music
[claudio@nowhere ~]$ [[ $(ls -ld "$ISDIR" | cut -c1) == 'd' ]] &&
echo "YES, $ISDIR is a directory." ||
echo "Sorry, $ISDIR is not a directory"
YES, /home/claudio/Music is a directory.
[claudio@nowhere ~]$ touch "empty file.txt"
[claudio@nowhere ~]$ ISDIR="$HOME/empty file.txt"
[claudio@nowhere ~]$ [[ $(ls -ld "$ISDIR" | cut -c1) == 'd' ]] &&
echo "YES, $ISDIR is a directory." ||
echo "Sorry, $ISDIR is not a directoy"
Sorry, /home/claudio/empty file.txt is not a directory
Make sure that all functions with non-void return type have a return
statement.
While some compilers automatically provide a default return value, others will send a SIGILL or SIGTRAP at runtime when trying to leave a function without a return value.

You will need to join the tables together and get a list of unique competitors that don't already exist in Competitors
.
This will insert unique records.
INSERT Competitors (cName)
SELECT DISTINCT Name
FROM CompResults cr LEFT JOIN Competitors c ON cr.Name = c.cName
WHERE c.Name IS NULL
There may come a time when this insert needs to be done quickly without being able to wait for the selection of unique names. In that case, you could insert the unique names into a temporary table, and then use that temporary table to insert into your real table. This works well because all the processing happens at the time you are inserting into a temporary table, so it doesn't affect your real table. Then when you have all the processing finished, you do a quick insert into the real table. I might even wrap the last part, where you insert into the real table, inside a transaction.
you need to add it like
insert into table1(date1) values('12-mar-2013');
Just type like "correct" case
"wrong"
git config --global mike.email "[email protected]"
git config --global mike.name "mike"
"correct"
git config --global user.email "[email protected]"
git config --global user.name "mike"
user.name is your account name in git-hub user.email is your email when you sign in git-hub.
Your query is probably fine. "The semaphore timeout period has expired" is a Network error, not a SQL Server timeout.
There is apparently some sort of network problem between you and the SQL Server.
edit: However, apparently the query runs for 15-20 min before giving the network error. That is a very long time, so perhaps the network error could be related to the long execution time. Optimization of the underlying View might help.
If [MyTable] in your example is a View, can you post the View Definition so that we can have a go at optimizing it?
If you just want to change the text for the leftBarButtonItem shown by the navigation controller together with the new view, you may change the title of the current view just before calling pushViewController to the wanted text and restore it in the viewHasDisappered callback for future showings of the current view.
This approach keeps the functionality (popViewController) and the appearance of the shown arrow intact.
It works for us at least with iOS 12, built with Xcode 10.1 ...
Changed if file not exists. Create empty file.

Step 1: Go to json.org to find the JSON library for whatever technology you're using to call this web service. Download and link to that library.
Step 2: Let's say you're using Java. You would use JSONArray like this:
JSONArray myArray=new JSONArray(queryResponse);
for (int i=0;i<myArray.length;i++){
JSONArray myInteriorArray=myArray.getJSONArray(i);
if (i==0) {
//this is the first one and is special because it holds the name of the query.
}else{
//do your stuff
String stateCode=myInteriorArray.getString(0);
String stateName=myInteriorArray.getString(1);
}
}
You can toggle filterstatus
value like this
filterstatus ^= 1;
So your function looks like
function showFilterItem(objButton) {
if (filterstatus == 0) {
$find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().showFilterItem();
objButton.value = "Hide Filter";
}
else {
$find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().hideFilterItem();
objButton.value = "Show filter";
}
filterstatus ^= 1;
}
It depends on what you are trying to do.
file, err := os.Open("file.txt")
fmt.print(file)
The reason it outputs &{0xc082016240}, is because you are printing the pointer value of a file-descriptor (*os.File
), not file-content. To obtain file-content, you may READ
from a file-descriptor.
To read all file content(in bytes) to memory, ioutil.ReadAll
package main
import (
"fmt"
"io/ioutil"
"os"
"log"
)
func main() {
file, err := os.Open("file.txt")
if err != nil {
log.Fatal(err)
}
defer func() {
if err = f.Close(); err != nil {
log.Fatal(err)
}
}()
b, err := ioutil.ReadAll(file)
fmt.Print(b)
}
But sometimes, if the file size is big, it might be more memory-efficient to just read in chunks: buffer-size, hence you could use the implementation of io.Reader.Read
from *os.File
func main() {
file, err := os.Open("file.txt")
if err != nil {
log.Fatal(err)
}
defer func() {
if err = f.Close(); err != nil {
log.Fatal(err)
}
}()
buf := make([]byte, 32*1024) // define your buffer size here.
for {
n, err := file.Read(buf)
if n > 0 {
fmt.Print(buf[:n]) // your read buffer.
}
if err == io.EOF {
break
}
if err != nil {
log.Printf("read %d bytes: %v", n, err)
break
}
}
}
Otherwise, you could also use the standard util package: bufio
, try Scanner
. A Scanner
reads your file in tokens: separator.
By default, scanner advances the token by newline (of course you can customise how scanner should tokenise your file, learn from here the bufio test).
package main
import (
"fmt"
"os"
"log"
"bufio"
)
func main() {
file, err := os.Open("file.txt")
if err != nil {
log.Fatal(err)
}
defer func() {
if err = f.Close(); err != nil {
log.Fatal(err)
}
}()
scanner := bufio.NewScanner(file)
for scanner.Scan() { // internally, it advances token based on sperator
fmt.Println(scanner.Text()) // token in unicode-char
fmt.Println(scanner.Bytes()) // token in bytes

Lastly, I would also like to reference you to this awesome site: go-lang file cheatsheet. It encompassed pretty much everything related to working with files in go-lang, hope you'll find it useful.
you can try this:
command = 'echo content |clip'
subprocess.check_call(command, shell=True)
You may also consider the following solution:
let sum = options.set0.concat(options.set1);
const codeHTML = '<ol>' + sum.reduce((html, item) => {
return html + "<li>" + item + "</li>";
}, "") + '</ol>';
document.querySelector("#list").innerHTML = codeHTML;
Another, admittedly pretty brute way is to just re-create the branch:
git fetch remote
git branch -f localbranch remote/remotebranch
This throws away the local outdated branch and re-creates one with the same name, so use with care ...
one more variant, but almost the same as Gumbos solution:
var isDebug = function(){
return window.location.href.search("[?&]debug=") != -1;
};
gcc has a so-called "case range" extension:
http://gcc.gnu.org/onlinedocs/gcc-4.2.4/gcc/Case-Ranges.html#Case-Ranges
I used to use this when I was only using gcc. Not much to say about it really -- it does sort of what you want, though only for ranges of values.
The biggest problem with this is that only gcc supports it; this may or may not be a problem for you.
(I suspect that for your example an if
statement would be a more natural fit.)
If you're sharing code between C and C++, remember to add the following to the shared.h
file:
#ifdef __cplusplus
extern "C" {
#endif
extern int my_global;
/* other extern declarations ... */
#ifdef __cplusplus
}
#endif
Updated answer from Stephen Groom for Swift 3
let email = "[email protected]"
let url = URL(string: "mailto:\(email)")
UIApplication.shared.openURL(url!)
Another alternative. I prefer this approach because it is less writing but the two accomplish the same thing.
IF COLUMNPROPERTY(OBJECT_ID('dbo.Person'), 'ColumnName', 'ColumnId') IS NULL
BEGIN
ALTER TABLE Person
ADD ColumnName VARCHAR(MAX) NOT NULL
END
I also noticed yours is looking for where table does exist that is obviously just this
if COLUMNPROPERTY( OBJECT_ID('dbo.Person'),'ColumnName','ColumnId') is not null
No rocket scien code require .Hope this simple and short code will help.
List linesList = File.ReadAllLines("myFile.txt").ToList();
linesList.RemoveAt(0);
File.WriteAllLines("myFile.txt"), linesList.ToArray());
OR use this
public void DeleteLinesFromFile(string strLineToDelete)
{
string strFilePath = "Provide the path of the text file";
string strSearchText = strLineToDelete;
string strOldText;
string n = "";
StreamReader sr = File.OpenText(strFilePath);
while ((strOldText = sr.ReadLine()) != null)
{
if (!strOldText.Contains(strSearchText))
{
n += strOldText + Environment.NewLine;
}
}
sr.Close();
File.WriteAllText(strFilePath, n);
}
The best practice is to check the Identity.IsAuthenticated
Property first and then get the usr.UserName
like this:
string userName = string.Empty;
if (System.Web.HttpContext.Current != null &&
System.Web.HttpContext.Current.User.Identity.IsAuthenticated)
{
System.Web.Security.MembershipUser usr = Membership.GetUser();
if (usr != null)
{
userName = usr.UserName;
}
}
DTD indicates the syntax of the XML element
XML Schemas are Microsoft's alternative to DTD for validating XML
For those who just need to save some int
value in the resources, you can do the following.
integers.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<integer name="default_value">100</integer>
</resources>
Code
int defaultValue = getResources().getInteger(R.integer.default_value);
os.path.getsize(path)
Return the size, in bytes, of path. Raise os.error if the file does not exist or is inaccessible.
Yes, this is confusing...
According to this blog post, it looks like this is an omission from WPF.
To make it work you need to use a style:
<Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
<Border.Style>
<Style>
<Setter Property="Border.Background" Value="Blue"/>
<Style.Triggers>
<Trigger Property="Border.IsMouseOver" Value="True">
<Setter Property="Border.Background" Value="Green" />
</Trigger>
</Style.Triggers>
</Style>
</Border.Style>
<TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
</Border>
I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.
To answer the question in your subject line,* yes, there are closures in Python, except they only apply inside a function, and also (in Python 2.x) they are read-only; you can't re-bind the name to a different object (though if the object is mutable, you can modify its contents). In Python 3.x, you can use the nonlocal
keyword to modify a closure variable.
def incrementer():
counter = 0
def increment():
nonlocal counter
counter += 1
return counter
return increment
increment = incrementer()
increment() # 1
increment() # 2
* The question origially asked about closures in Python.
You can get good Time Series graphs in Excel, the way you want, but you have to work with a few quirks.
Be sure to select "Scatter Graph" (with a line option). This is needed if you have non-uniform time stamps, and will scale the X-axis accordingly.
In your data, you need to add a column with the mid-point. Here's what I did with your sample data. (This trick ensures that the data gets plotted at the mid-point, like you desire.)
You can format the x-axis options with this menu. (Chart->Design->Layout)
Select "Axes" and go to Primary Horizontal Axis, and then select "More Primary Horizontal Axis Options"
Set up the options you wish. (Fix the starting and ending points.)
And you will get a graph such as the one below.
You can then tweak many of the options, label the axes better etc, but this should get you started.
Hope this helps you move forward.
You want the :checkbox:checked
selector and map
to create an array of the values:
var checkedValues = $('input:checkbox:checked').map(function() {
return this.value;
}).get();
If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked')
, or for a common name $('input[name="Foo"]:checked')
- Update -
If you don't need IE support then you can now make the map()
call more succinct by using an arrow function:
var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();
It appears that your command is correct so the problem might be due to missing support for PNG (). You can check with convert -list configure
or just try the following:
sudo yum install libpng libpng-devel
Easier method is window.location.href = "http://example.com/new_url";
But what if you want to check if username and password whether empty or not using JavaScript and send it to the php to check whether user in the database. You can do this easily following this code.
html form -
<form name="myForm" onsubmit="return validateForm()" method="POST" action="login.php" >
<input type="text" name="username" id="username" />
<input type="password" name="password" id="password" />
<input type="submit" name="submitBt"value="LogIn" />
</form>
javascript validation-
function validateForm(){
var uname = document.forms["myForm"]["username"].value;
var pass = document.forms["myForm"]["password"].value;
if((!isEmpty(uname, "Log In")) && (!isEmpty(pass, "Password"))){
return true;
}else{
return false;
}
}
function isEmpty(elemValue, field){
if((elemValue == "") || (elemValue == null)){
alert("you can not have "+field+" field empty");
return true;
}else{
return false;
}
}
check if user in the database using php
<?php
$con = mysqli_connect("localhost","root","1234","users");
if(mysqli_connect_errno()){
echo "Couldn't connect ".mysqli_connect_error();
}else{
//echo "connection successful <br />";
}
$uname_tb = $_POST['username'];
$pass_tb = $_POST['password'];
$query ="SELECT * FROM user";
$result = mysqli_query($con,$query);
while($row = mysqli_fetch_array($result)){
if(($row['username'] == $uname_tb) && ($row['password'] == $pass_tb)){
echo "Login Successful";
header('Location: dashbord.php');
exit();
}else{
echo "You are not in our database".mysqli_connect_error();
}
}
mysqli_close($con);
?>
You need to goto Tools-->Options--->Select Resharper--->Click on suspend now,to disable it
Besides the usages that JAiro mentioned, I like this one:
def getConnectionProps = {
( Config.getHost, Config.getPort, Config.getSommElse, Config.getSommElsePartTwo )
}
If someone needs all connection properties, he can do:
val ( host, port, sommEsle, someElsePartTwo ) = getConnectionProps
If you need just a host and a port, you can do:
val ( host, port, _, _ ) = getConnectionProps
I think the fix is relative easy without disabling this feature.
def kos_root():
"""Return the pathname of the KOS root directory."""
global _kos_root
if _kos_root: return _kos_root
All you need to do is add the triple double quotes string in every function.
You have make div as server control using following code,
<div class="tab-pane active" id="portlet_tab1" runat="server">
then this div will be accessible in code behind.
If you add your site to "Local Intranet" in
Chrome > Options > Under the Hood > Change Proxy Settings > Security (tab) > Local Intranet/Sites > Advanced.
Add you site URL here and it will work.
Update for New Version of Chrome
Chrome > Settings > Advanced > System > Open Proxy Settings > Security (tab) > Local Intranet > Sites (button) > Advanced.
If you want the executable:
System.Reflection.Assembly.GetEntryAssembly().Location
If you want the assembly that's consuming your library (which could be the same assembly as above, if your code is called directly from a class within your executable):
System.Reflection.Assembly.GetCallingAssembly().Location
If you'd like just the filename and not the path, use:
Path.GetFileName(System.Reflection.Assembly.GetEntryAssembly().Location)
You should have a default server for catch-all, you can return 404
or better to not respond at all (will save some bandwidth) by returning 444
which is nginx specific HTTP response that simply close the connection and return nothing
server {
listen 80 default_server;
server_name _; # some invalid name that won't match anything
return 444;
}
I've recently found how to trigger mouse click event via jQuery.
<script type="text/javascript">
var a = $('.path > .to > .element > a')[0];
var e = document.createEvent('MouseEvents');
e.initEvent( 'click', true, true );
a.dispatchEvent(e);
</script>
Yes it may differ but there are some limitations.
Before Java 5.0, when you override a method, both parameters and return type must match exactly. Java 5.0 it introduces a new facility called covariant return type. You can override a method with the same signature but return a subclass of the object returned.
In another words, a method in a subclass can return an object whose type is a subclass of the type returned by the method with the same signature in the superclass.
Instead of '2013-04-12' whose meaning depends on the local culture, use '20130412' which is recognized as the culture invariant format.
If you want to compare with December 4th, you should write '20131204'. If you want to compare with April 12th, you should write '20130412'.
The article Write International Transact-SQL Statements from SQL Server's documentation explains how to write statements that are culture invariant:
Applications that use other APIs, or Transact-SQL scripts, stored procedures, and triggers, should use the unseparated numeric strings. For example, yyyymmdd as 19980924.
EDIT
Since you are using ADO, the best option is to parameterize the query and pass the date value as a date parameter. This way you avoid the format issue entirely and gain the performance benefits of parameterized queries as well.
UPDATE
To use the the the ISO 8601 format in a literal, all elements must be specified. To quote from the ISO 8601 section of datetime's documentation
To use the ISO 8601 format, you must specify each element in the format. This also includes the T, the colons (:), and the period (.) that are shown in the format.
... the fraction of second component is optional. The time component is specified in the 24-hour format.
I encountered the exact same problem today, Ryan.
In my src (or your root) directory, my log4j.properties file now has the following addition

Thanks for the heads up as to how to do this, Benjamin.
DBMS: is a software system that allows Defining, Creation, Querying, Update, and Administration of data stored in data files.
Features:
RDBMS: is a DBMS that is based on Relational model that stores data in tabular form.
Features:
To make @NotNull
active you need Lombok:
https://projectlombok.org/features/NonNull
import lombok.NonNull;
value_counts omits NaN by default so you're most likely dealing with "".
So you can just filter them out like
filter = df["Tenant"] != ""
dfNew = df[filter]

Well if a job's worth doing... I was able to get something up and running in about 30 mins. Disclaimer: there's quite a few known (and probably a few as yet unknown) problems with it, but it makes me wonder what on Earth the other 2920 lines of JS are there for in many offerings!

Try this:
@echo off
for /f "tokens=*" %%a in (input.txt) do (
echo line=%%a
)
pause
because of the tokens=*
everything is captured into %a
edit: to reply to your comment, you would have to do that this way:
@echo off
for /f "tokens=*" %%a in (input.txt) do call :processline %%a
pause
goto :eof
:processline
echo line=%*
goto :eof
:eof
Because of the spaces, you can't use %1
, because that would only contain the part until the first space. And because the line contains quotes, you can also not use :processline "%%a"
in combination with %~1
. So you need to use %*
which gets %1 %2 %3 ...
, so the whole line.

A div is a block element, and will span the width of the container unless a width is set. A span is an inline element, and will have the width of the text inside it. Currently, you are trying to set align as a CSS property. Align is an attribute.
<span align="center" style="border:1px solid red;">
This is some text in a div element!
</span>
However, the align attribute is deprecated. You should use the CSS text-align
property on the container.
<div style="text-align: center;">
<span style="border:1px solid red;">
This is some text in a div element!
</span>
</div>
Just noting that the reason actually is that the size of the enum is not yet known after forward declaration. Well, you use forward declaration of a struct to be able to pass a pointer around or refer to an object from a place that's refered to in the forward declared struct definition itself too.
Forward declaring an enum would not be too useful, because one would wish to be able to pass around the enum by-value. You couldn't even have a pointer to it, because i recently got told some platforms use pointers of different size for char than for int or long. So it all depends on the content of the enum.
The current C++ Standard explicitly disallows doing something like
enum X;
(in 7.1.5.3/1
). But the next C++ Standard due to next year allows the following, which convinced me the problem actually has to do with the underlying type:
enum X : int;
It's known as a "opaque" enum declaration. You can even use X by value in the following code. And its enumerators can later be defined in a later redeclaration of the enumeration. See 7.2
in the current working draft.
Try calling it like: obj.some_function( '1', 2, '3', g="foo", h="bar" )
. After the required positional arguments, you can specify specific optional arguments by name.
Take a look at Remote Manager. But seems to me it doesn't work correctly with devices which have big screen. Although, you can try DEMO before.
tick_params is very useful for setting tick properties. Labels can be moved to the top with:
ax.tick_params(labelbottom=False,labeltop=True)
How about
sub foo()
dim r As Range, rows As Long, i As Long
Set r = ActiveSheet.Range("A1:Z50")
rows = r.rows.Count
For i = rows To 1 Step (-1)
If WorksheetFunction.CountA(r.rows(i)) = 0 Then r.rows(i).Delete
Next
End Sub
Try this
Option Explicit
Sub Sample()
Dim i As Long
Dim DelRange As Range
On Error GoTo Whoa
Application.ScreenUpdating = False
For i = 1 To 50
If Application.WorksheetFunction.CountA(Range("A" & i & ":" & "Z" & i)) = 0 Then
If DelRange Is Nothing Then
Set DelRange = Range("A" & i & ":" & "Z" & i)
Else
Set DelRange = Union(DelRange, Range("A" & i & ":" & "Z" & i))
End If
End If
Next i
If Not DelRange Is Nothing Then DelRange.Delete shift:=xlUp
LetsContinue:
Application.ScreenUpdating = True
Exit Sub
Whoa:
MsgBox Err.Description
Resume LetsContinue
End Sub
IF you want to delete the entire row then use this code
Option Explicit
Sub Sample()
Dim i As Long
Dim DelRange As Range
On Error GoTo Whoa
Application.ScreenUpdating = False
For i = 1 To 50
If Application.WorksheetFunction.CountA(Range("A" & i & ":" & "Z" & i)) = 0 Then
If DelRange Is Nothing Then
Set DelRange = Rows(i)
Else
Set DelRange = Union(DelRange, Rows(i))
End If
End If
Next i
If Not DelRange Is Nothing Then DelRange.Delete shift:=xlUp
LetsContinue:
Application.ScreenUpdating = True
Exit Sub
Whoa:
MsgBox Err.Description
Resume LetsContinue
End Sub
We want code that is robust and simple. This solution works on old devices and newer devices.

There is no way you can delete a pull request yourself -- you and the repo owner (and all users with push access to it) can close it, but it will remain in the log. This is part of the philosophy of not denying/hiding what happened during development.
However, if there are critical reasons for deleting it (this is mainly violation of Github Terms of Service), Github support staff will delete it for you.
Whether or not they are willing to delete your PR for you is something you can easily ask them, just drop them an email at [email protected]
UPDATE: Currently Github requires support requests to be created here: https://support.github.com/contact
I also like the solution that you just post an extra input field, using JavaScript seems a little hacky to me.
Depending on what you use for you backend will depend on which input goes first.
For a server backend where the first occurrence is used (JSP) you should do the following.
<input type="checkbox" value="1" name="checkbox_1"/>
<input type="hidden" value="0" name="checkbox_1"/>
For a server backend where the last occurrence is used (PHP,Rails) you should do the following.
<input type="hidden" value="0" name="checkbox_1"/>
<input type="checkbox" value="1" name="checkbox_1"/>
For a server backend where all occurrences are stored in a list data type ([]
,array
). (Python / Zope)
You can post in which ever order you like, you just need to try to get the value from the input with the checkbox
type attribute. So the first index of the list if the checkbox was before the hidden element and the last index if the checkbox was after the hidden element.
For a server backend where all occurrences are concatenated with a comma (ASP.NET / IIS)
You will need to (split/explode) the string by using a comma as a delimiter to create a list data type. ([]
)
Now you can attempt to grab the first index of the list if the checkbox was before the hidden element and grab the last index if the checkbox was after the hidden element.
You can use a very nice tool called Stetho
by adding this to build.gradle
file:
compile 'com.facebook.stetho:stetho:1.4.1'
And initialized it inside your Application
or Activity
onCreate()
method:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Stetho.initializeWithDefaults(this);
setContentView(R.layout.activity_main);
}

Using DELETE with a Body is risky... I prefer this approach for List Operations over REST:
Regular Operations
GET /objects/ Gets all Objects
GET /object/ID Gets an Object with specified ID
POST /objects Adds a new Object
PUT /object/ID Adds an Object with specified ID, Updates an Object
DELETE /object/ID Deletes the object with specified ID
All Custom actions are POST
POST /objects/addList Adds a List or Array of Objects included in body
POST /objects/deleteList Deletes a List of Objects included in body
POST /objects/customQuery Creates a List based on custom query in body
If a client doesn't support your extended operations they can work in the regular way.
You can use codecs.
import codecs
with open("test.txt",'r') as filehandle:
content = filehandle.read()
if content[:3] == codecs.BOM_UTF8:
content = content[3:]
print content.decode("utf-8")
We can use zPosition in ios
if we have a view named salonDetailView
eg : @IBOutlet weak var salonDetailView: UIView!
and have UIView for GMSMapView
eg : @IBOutlet weak var mapViewUI: GMSMapView!
To show the View salonDetailView upper of the mapViewUI
use zPosition as below
salonDetailView.layer.zPosition = 1
The commands dict.items()
, dict.keys()
and dict.values()
return a copy of the dictionary's list of (k, v)
pair, keys and values.
This could take a lot of memory if the copied list is very large.
The commands dict.iteritems()
, dict.iterkeys()
and dict.itervalues()
return an iterator over the dictionary’s (k, v)
pair, keys and values.
The commands dict.viewitems()
, dict.viewkeys()
and dict.viewvalues()
return the view objects, which can reflect the dictionary's changes.
(I.e. if you del
an item or add a (k,v)
pair in the dictionary, the view object can automatically change at the same time.)
$ python2.7
>>> d = {'one':1, 'two':2}
>>> type(d.items())
<type 'list'>
>>> type(d.keys())
<type 'list'>
>>>
>>>
>>> type(d.iteritems())
<type 'dictionary-itemiterator'>
>>> type(d.iterkeys())
<type 'dictionary-keyiterator'>
>>>
>>>
>>> type(d.viewitems())
<type 'dict_items'>
>>> type(d.viewkeys())
<type 'dict_keys'>
In Py3.x, things are more clean, since there are only dict.items()
, dict.keys()
and dict.values()
available, which return the view objects just as dict.viewitems()
in Py2.x did.
Just as @lvc noted, view object isn't the same as iterator, so if you want to return an iterator in Py3.x, you could use iter(dictview)
:
$ python3.3
>>> d = {'one':'1', 'two':'2'}
>>> type(d.items())
<class 'dict_items'>
>>>
>>> type(d.keys())
<class 'dict_keys'>
>>>
>>>
>>> ii = iter(d.items())
>>> type(ii)
<class 'dict_itemiterator'>
>>>
>>> ik = iter(d.keys())
>>> type(ik)
<class 'dict_keyiterator'>
There are several different ways to check if an argument was passed to a function. In addition to the two you mentioned in your (original) question - checking arguments.length
or using the ||
operator to provide default values - one can also explicitly check the arguments for undefined
via argument2 === undefined
or typeof argument2 === 'undefined'
if one is paranoid (see comments).
Using the ||
operator has become standard practice - all the cool kids do it - but be careful: The default value will be triggered if the argument evaluates to false
, which means it might actually be undefined
, null
, false
, 0
, ''
(or anything else for which Boolean(...)
returns false
).
So the question is when to use which check, as they all yield slightly different results.
Checking arguments.length
exhibits the 'most correct' behaviour, but it might not be feasible if there's more than one optional argument.
The test for undefined
is next 'best' - it only 'fails' if the function is explicitly called with an undefined
value, which in all likelyhood should be treated the same way as omitting the argument.
The use of the ||
operator might trigger usage of the default value even if a valid argument is provided. On the other hand, its behaviour might actually be desired.
To summarize: Only use it if you know what you're doing!
In my opinion, using ||
is also the way to go if there's more than one optional argument and one doesn't want to pass an object literal as a workaround for named parameters.
Another nice way to provide default values using arguments.length
is possible by falling through the labels of a switch statement:
function test(requiredArg, optionalArg1, optionalArg2, optionalArg3) {
switch(arguments.length) {
case 1: optionalArg1 = 'default1';
case 2: optionalArg2 = 'default2';
case 3: optionalArg3 = 'default3';
case 4: break;
default: throw new Error('illegal argument count')
}
// do stuff
}
This has the downside that the programmer's intention is not (visually) obvious and uses 'magic numbers'; it is therefore possibly error prone.
When you do new Promise((resolve)...
the type inferred was Promise<{}>
because you should have used new Promise<number>((resolve)
.
It is interesting that this issue was only highlighted when the async
keyword was added. I would recommend reporting this issue to the TS team on GitHub.
There are many ways you can get around this issue. All the following functions have the same behavior:
const whatever1 = () => {
return new Promise<number>((resolve) => {
resolve(4);
});
};
const whatever2 = async () => {
return new Promise<number>((resolve) => {
resolve(4);
});
};
const whatever3 = async () => {
return await new Promise<number>((resolve) => {
resolve(4);
});
};
const whatever4 = async () => {
return Promise.resolve(4);
};
const whatever5 = async () => {
return await Promise.resolve(4);
};
const whatever6 = async () => Promise.resolve(4);
const whatever7 = async () => await Promise.resolve(4);
In your IDE you will be able to see that the inferred type for all these functions is () => Promise<number>
.
/*This code will use gridview sum inside data list*/
SumOFdata(grd_DataDetail);
private void SumOFEPFWages(GridView grd)
{
Label lbl_TotAmt = (Label)grd.FooterRow.FindControl("lblTotGrossW");
/*Sum of the total Amount of the day*/
foreach (GridViewRow gvr in grd.Rows)
{
Label lbl_Amount = (Label)gvr.FindControl("lblGrossS");
lbl_TotAmt.Text = (Convert.ToDouble(lbl_Amount.Text) + Convert.ToDouble(lbl_TotAmt.Text)).ToString();
}
}
There is a simple workaround that doesn't require you to change any code, and it works in Laravel 4 just as well.
You just use an assignment operator (=
) in the expression passed to an @if
statement, instead of (for instance) an operator such as ==
.
@if ($variable = 'any data, be it string, variable or OOP') @endif
Then you can use it anywhere you can use any other variable
{{ $variable }}
The only downside is your assignment will look like a mistake to someone not aware that you're doing this as a workaround.
You are creating a dictionary first, then passing that dictionary to an OrderedDict
. For Python versions < 3.6 (*), by the time you do that, the ordering is no longer going to be correct. dict
is inherently not ordered.
Pass in a sequence of tuples instead:
ship = [("NAME", "Albatross"),
("HP", 50),
("BLASTERS", 13),
("THRUSTERS", 18),
("PRICE", 250)]
ship = collections.OrderedDict(ship)
What you see when you print the OrderedDict
is it's representation, and it is entirely correct. OrderedDict([('PRICE', 250), ('HP', 50), ('NAME', 'Albatross'), ('BLASTERS', 13), ('THRUSTERS', 18)])
just shows you, in a reproducable representation, what the contents are of the OrderedDict
.
(*): In the CPython 3.6 implementation, the dict
type was updated to use a more memory efficient internal structure that has the happy side effect of preserving insertion order, and by extension the code shown in the question works without issues. As of Python 3.7, the Python language specification has been updated to require that all Python implementations must follow this behaviour. See this other answer of mine for details and also why you'd still may want to use an OrderedDict()
for certain cases.
In the HTML page you have to to put your css code between the tags, while in the body a div which has as id rectangle. Here the code:

Access dynamic object properties in js we can use bracket notation.
const something = {
bar: "Foobar!"
};
const foo = 'bar';
console.log(something[foo]); // "Foobar!"
In Bootstrap 4 you can use classes like mt-5
, mb-5
, my-5
, mx-5
(y for both top and bottom, x for both left and right).
According to their site:
The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.
void addToSpecific()
{
int n;
int f=0; //flag
Node *temp=H; //H-Head, T-Tail
if(NULL!=H)
{
cout<<"Enter the Number"<<endl;
cin>>n;
while(NULL!=(temp->getNext()))
{
if(n==(temp->getInfo()))
{
f=1;
break;
}
temp=temp->getNext();
}
}
if(NULL==H)
{
Node *nn=new Node();
nn->setInfo();
nn->setNext(NULL);
T=H=nn;
}
else if(0==f)
{
Node *nn=new Node();
nn->setInfo();
nn->setNext(NULL);
T->setNext(nn);
T=nn;
}
else if(1==f)
{
Node *nn=new Node();
nn->setInfo();
nn->setNext(NULL);
nn->setNext((temp->getNext()));
temp->setNext(nn);
}
}
It's very important to point out that view.layoutIfNeeded()
applies to the view subviews only.
Therefore to animate the view constraint, it is important to call it on the view-to-animate superview as follows:
topConstraint.constant = heightShift
UIView.animate(withDuration: 0.3) {
// request layout on the *superview*
self.view.superview?.layoutIfNeeded()
}
An example for a simple layout as follows:
class MyClass {
/// Container view
let container = UIView()
/// View attached to container
let view = UIView()
/// Top constraint to animate
var topConstraint = NSLayoutConstraint()
/// Create the UI hierarchy and constraints
func createUI() {
container.addSubview(view)
// Create the top constraint
topConstraint = view.topAnchor.constraint(equalTo: container.topAnchor, constant: 0)
view.translatesAutoresizingMaskIntoConstraints = false
// Activate constaint(s)
NSLayoutConstraint.activate([
topConstraint,
])
}
/// Update view constraint with animation
func updateConstraint(heightShift: CGFloat) {
topConstraint.constant = heightShift
UIView.animate(withDuration: 0.3) {
// request layout on the *superview*
self.view.superview?.layoutIfNeeded()
}
}
}
Aight fam, after some research and experimenting, I think the best approach is to have the thing's height at 0px
, and let it transition to an exact height. You get the exact height with JavaScript. The JavaScript isn't doing the animating, it's just changing the height value. Check it:
function setInfoHeight() {
$(window).on('load resize', function() {
$('.info').each(function () {
var current = $(this);
var closed = $(this).height() == 0;
current.show().height('auto').attr('h', current.height() );
current.height(closed ? '0' : current.height());
});
});
Whenever the page loads or is resized, the element with class info
will get its h
attribute updated. Then you could have a button trigger the style="height: __"
to set it to that previously set h
value.
function moreInformation() {
$('.icon-container').click(function() {
var info = $(this).closest('.dish-header').next('.info'); // Just the one info
var icon = $(this).children('.info-btn'); // Select the logo
// Stop any ongoing animation loops. Without this, you could click button 10
// times real fast, and watch an animation of the info showing and closing
// for a few seconds after
icon.stop();
info.stop();
// Flip icon and hide/show info
icon.toggleClass('flip');
// Metnod 1, animation handled by JS
// info.slideToggle('slow');
// Method 2, animation handled by CSS, use with setInfoheight function
info.toggleClass('active').height(icon.is('.flip') ? info.attr('h') : '0');
});
};
Here's the styling for the info
class.
.info {
display: inline-block;
height: 0px;
line-height: 1.5em;
overflow: hidden;
padding: 0 1em;
transition: height 0.6s, padding 0.6s;
&.active {
border-bottom: $thin-line;
padding: 1em;
}
}
I used this on one of my projects so class names are specific. You can change them up however you like.
The styling might not be supported cross-browser. Works fine in chrome.
Below is the live example for this code. Just click on the ?
icon to start the animation
In my case $(document).ready(function() was missing. Try this.
$(document).ready(function(){
("#table tr").click(function(){
$(this).addClass('selected').siblings().removeClass('selected');
var value=$(this).find('td:first').html();
alert(value);
});
$('.ok').on('click', function(e){
alert($("#table tr.selected td:first").html());
});
});
Got the answer: I should not use parentheses after return ()
. This works:
return <div> <Search_Bar /> </div>
If you want to write multiline, then return ( ...
Your starting parenthesis should be on the same line as return
.
For Boto3 , use this code.
import boto3
from botocore.client import Config
s3 = boto3.resource('s3',
aws_access_key_id='xxxxxx',
aws_secret_access_key='xxxxxx',
region_name='us-south-1',
config=Config(signature_version='s3v4')
)
BComp.exe works in multiple-tabbed scenario as well, so there is no need to add /solo unless you really want separate windows for each file comparison. Tested/verified on Beyond Compare 3 and 4. Moral: use BComp.exe, not BCompare.exe, for VS external compare tool configuration.
No, not all browsers support the sizes
attribute:
Note that some platforms define specific sizes:
manifest.json
if it is present. Plus, Chrome uses the Apple Touch icon for bookmarks.in angular2 2.1.1 I was not able to catch the exception using the (data),(error) pattern, so I implemented it using .catch(...).
It's nice because it can be used with all other Observable chained methods like .retry .map etc.
import {Observable} from 'rxjs/Rx';
Http
.put(...)
.catch(err => {
notify('UI error handling');
return Observable.throw(err); // observable needs to be returned or exception raised
})
.subscribe(data => ...) // handle success
from documentation:
Returns
(Observable): An observable sequence containing elements from consecutive source sequences until a source sequence terminates successfully.
Use this:
this.CenterToScreen(); // This will take care of the current form
Works great, minimal setup and no third parties.
According to Chrome's documentation:
Here's the updated workflow:What happens when you blackbox a script?
Exceptions thrown from library code will not pause (if Pause on exceptions is enabled), Stepping into/out/over bypasses the library code, Event listener breakpoints don't break in library code, The debugger will not pause on any breakpoints set in library code. The end result is you are debugging your application code instead of third party resources.
jquery\..*\.js
(glob pattern/human translation: jquery.*.js
)|
, like so: jquery\..*\.js|include\.postload\.js
(which acts like an "or this pattern", so to speak. Or keep adding them with the "Add" button.Bonus tip! I use Regex101 regularly (but there are many others: ) to quickly test my rusty regex patterns and find out where I'm wrong with the step-by-step regex debugger. If you are not yet "fluent" in Regular Expressions I recommend you start using sites that help you write and visualize them such as http://buildregex.com/ and https://www.debuggex.com/
You can also use the context menu when working in the Sources panel. When viewing a file, you can right-click in the editor and choose Blackbox Script. This will add the file to the list in the Settings panel:
It's an excellent tool to have:
Visual Event is an open-source Javascript bookmarklet which provides debugging information about events that have been attached to DOM elements. Visual Event shows:
- Which elements have events attached to them
- The type of events attached to an element
- The code that will be run with the event is triggered
- The source file and line number for where the attached function was defined (Webkit browsers and Opera only)
You can pause the code when you click somewhere in the page, or when the DOM is modified... and other kinds of JS breakpoints that will be useful to know. You should apply blackboxing here to avoid a nightmare.
In this instance, I want to know what exactly goes on when I click the button.
Open Dev Tools -> Sources tab, and on the right find Event
Listener Breakpoints
:
Expand Mouse
and select click
With Dev Tools activated, you can search the whole codebase (all code in all files) with ?+?+F or:
and searching #envio
or whatever the tag/class/id you think starts the party and you may get somewhere faster than anticipated.
Be aware sometimes there's not only an img
but lots of elements stacked, and you may not know which one triggers the code.
If this is a bit out of your knowledge, take a look at Chrome's tutorial on debugging.
Similar to blubb's answer. I suggest building them with lambda functions to reduce code. Like this:
User = lambda passwd, hair, name: {'password':passwd, 'hair':hair, 'name':name}
#Col Username Password Hair Color Real Name
config = {'st3v3' : User('password', 'blonde', 'Steve Booker'),
'blubb' : User('12345678', 'black', 'Bubb Ohaal'),
'suprM' : User('kryptonite', 'black', 'Clark Kent'),
#...
}
#...
config['st3v3']['password'] #> password
config['blubb']['hair'] #> black
This does smell like you may want to make a class, though.
Or, as MarkM noted, you could use namedtuple
from collections import namedtuple
#...
User = namedtuple('User', ['password', 'hair', 'name']}
#Col Username Password Hair Color Real Name
config = {'st3v3' : User('password', 'blonde', 'Steve Booker'),
'blubb' : User('12345678', 'black', 'Bubb Ohaal'),
'suprM' : User('kryptonite', 'black', 'Clark Kent'),
#...
}
#...
config['st3v3'].password #> passwd
config['blubb'].hair #> black
You could try a formatter like this
They will always be limited because they don't (and can't) know what user defined functions you may have defined in your database (or which built-in functions you have or don't have access to).
You could also look at ANTLR (but that would be an offline solution)
for i in range(len(ints)):
print i, ints[i]
You could use the between function to get all records between 2010-08-03 00:00:00:000 AND 2010-08-03 23:59:59:000
Use the following:
getActivity().setTitle("YOUR_TITLE");
pip has a --no-dependencies
switch. You should use that.
For more information, run pip install -h
, where you'll see this line:
--no-deps, --no-dependencies
Ignore package dependencies
For immutable data types:
l = [0] * 100
# [0, 0, 0, 0, 0, ...]
l = ['foo'] * 100
# ['foo', 'foo', 'foo', 'foo', ...]
For values that are stored by reference and you may wish to modify later (like sub-lists, or dicts):
l = [{} for x in range(100)]
(The reason why the first method is only a good idea for constant values, like ints or strings, is because only a shallow copy is does when using the <list>*<number>
syntax, and thus if you did something like [{}]*100
, you'd end up with 100 references to the same dictionary - so changing one of them would change them all. Since ints and strings are immutable, this isn't a problem for them.)
If you want to add to an existing list, you can use the extend()
method of that list (in conjunction with the generation of a list of things to add via the above techniques):
a = [1,2,3]
b = [4,5,6]
a.extend(b)
# a is now [1,2,3,4,5,6]
@rob answer will work most of the times, but it might not work as you expect with long inputs.
That is what you should be using instead:
const stdin = process.openStdin();
let content = '';
stdin.addListener('data', d => {
content += d.toString();
});
stdin.addListener('end', () => {
console.info(`Input: ${content}`);
});
Explanation on why this solution works:
addListener('data')
works like a buffer, callback will be called when it is full or/and its the end of input.
What about long inputs? A single 'data'
callback will not be enough, hence it you will get your input split in two or more parts. That is often not convenient.
addListener('end')
will notify us when the stdin reader is done reading our input. Since we have been storing the previous data, we can now read and process it all together.
Alternatively, you could create a regular Mac OS X application from your script using Platypus

Declaring a PRIMARY KEY
or UNIQUE
constraint causes SQL Server to automatically create an index.
An unique index can be created without matching a constraint, but a constraint (either primary key or unique) cannot exist without having a unique index.
From here, the creation of a constraint will:
and at the same time dropping the constraint will drop the associated index.
So, is there actual difference between a PRIMARY KEY
or UNIQUE INDEX
:
NULL
values are not allowed in PRIMARY KEY
, but allowed in UNIQUE
index; and like in set operators (UNION, EXCEPT, INTERSECT), here NULL = NULL
which means that you can have only one value as two NULL
s are find as duplicates of each other;PRIMARY KEY
may exists per table while 999 unique indexes can be createdPRIMARY KEY
constraint is created, it is created as clustered unless there is already a clustered index on the table or NONCLUSTERED
is used in its definition; when UNIQUE
index is created, it is created as NONCLUSTERED
unless it is not specific to be CLUSTERED
and such already does not exist;not() is a function in xpath (as opposed to an operator), so
//a[not(contains(@id, 'xx'))]
I've done something like this.
private void Form_FormClosing(object sender, FormClosingEventArgs e)
{
if ((sender as Form).ActiveControl is Button)
{
//CloseButton
}
else
{
//The X has been clicked
}

Your HTML:
<div class="img-with-text">
<img src="yourimage.jpg" alt="sometext" />
<p>Some text</p>
</div>
If you know the width of your image, your CSS:
.img-with-text {
text-align: justify;
width: [width of img];
}
.img-with-text img {
display: block;
margin: 0 auto;
}
Otherwise your text below the image will free-flow. To prevent this, just set a width to your container.
The accepted answer is accurate, but make sure that you also install all necessary dependencies as well. Installing using the CLI or web seems to take care of this, but my plugins were not showing up in the browser or using java -jar jenkins-cli.jar -s http://localhost:8080 list-plugins
until I also installed the dependencies.
The first approach is valid, but doesn't work if your string has blank spaces (@" "
). So you must clear this white spaces before testing it.
This code clear all the blank spaces on both sides of the string:
[stringObject stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet] ];
One good idea is create one macro, so you don't have to type this monster line:
#define allTrim( object ) [object stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet] ]
Now you can use:
NSString *emptyString = @" ";
if ( [allTrim( emptyString ) length] == 0 ) NSLog(@"Is empty!");
String.format("%03d", 1) // => "001"
// ¦¦¦ +-- print the number one
// ¦¦+------ ... as a decimal integer
// ¦+------- ... minimum of 3 characters wide
// +-------- ... pad with zeroes instead of spaces

Unirest.config().verifySsl(false);
HttpResponse<String> response = null;
try {
Gson gson = new Gson();
response = Unirest.post("your_api_url")
.header("Authorization", "Basic " + "authkey")

.asString();
System.out.println("------RESPONSE -------"+ gson.toJson(response.getBody()));
} catch (Exception e) {
System.out.println("------RESPONSE ERROR--");
e.printStackTrace();
}
}
Here is my take on it on a big set of data - such as a legacy dBase table to find duplicate parts
# Assuming ps is an array of 20000 part numbers & we want to find duplicates
# actually had to it recently.
# having a result hash with part number and number of times part is
# duplicated is much more convenient in the real world application
# Takes about 6 seconds to run on my data set
# - not too bad for an export script handling 20000 parts
h = {};
# or for readability
h = {} # result hash
ps.select{ |e|
ct = ps.count(e)
h[e] = ct if ct > 1
}; nil # so that the huge result of select doesn't print in the console
Just check for
if(table.rows[0][0] == null)
{
//Whatever I want to do
}
or you could
if(t.Rows[0].IsNull(0))
{
//Whatever I want to do
}

$this->db->join('Soundtrack c', 'c.album_id=a.album_id', 'left');
$this->db->where('c.album_id',$id);
$this->db->order_by('c.track_title','asc');

Java 8 provides Byte.toUnsignedInt
to convert byte
to int
by unsigned conversion. In Oracle's JDK this is simply implemented as return ((int) x) & 0xff;
because HotSpot already understands how to optimize this pattern, but it could be intrinsified on other VMs. More importantly, no prior knowledge is needed to understand what a call to toUnsignedInt(foo)
does.
In total, Java 8 provides methods to convert byte
and short
to unsigned int
and long
, and int
to unsigned long
. A method to convert byte
to unsigned short
was deliberately omitted because the JVM only provides arithmetic on int
and long
anyway.
To convert an int back to a byte, just use a cast: (byte)someInt
. The resulting narrowing primitive conversion will discard all but the last 8 bits.
There're some keys about from the book MCSD Certification Toolkit (exam 70-483) pag 193:
destructor ˜(it's almost equal to) base.Finalize()
, The destructor is converted into an override version of the Finalize method that executes the destructor’s code and then calls the base class’s Finalize method. Then its totally non deterministic you can't able to know when will be called because depends on GC.
If a class contains no managed resources and no unmanaged resources, it shouldn't implement IDisposable
or have a destructor.
If the class has only managed resources, it should implement IDisposable
but it shouldn't have a destructor. (When the destructor executes, you can’t be sure managed objects still
exist, so you can’t call their Dispose()
methods anyway.)
If the class has only unmanaged resources, it needs to implement IDisposable
and needs a destructor in case the program doesn’t call Dispose()
.
Dispose()
method must be safe to run more than once. You can achieve that by using a variable to keep track of whether it has been run before.
Dispose()
should free both managed and unmanaged resources.
The destructor should free only unmanaged resources. When the destructor executes, you
can’t be sure managed objects still exist, so you can’t call their Dispose methods anyway. This is obtained by using the canonical protected void Dispose(bool disposing)
pattern, where only managed resources are freed (disposed) when disposing == true
.
After freeing resources, Dispose()
should call GC.SuppressFinalize
, so the object can
skip the finalization queue.
An Example of a an implementation for a class with unmanaged and managed resources:
using System;
class DisposableClass : IDisposable
{
// A name to keep track of the object.
public string Name = "";
// Free managed and unmanaged resources.
public void Dispose()
{
FreeResources(true);
// We don't need the destructor because
// our resources are already freed.
GC.SuppressFinalize(this);
}
// Destructor to clean up unmanaged resources
// but not managed resources.
~DisposableClass()
{
FreeResources(false);
}
// Keep track if whether resources are already freed.
private bool ResourcesAreFreed = false;
// Free resources.
private void FreeResources(bool freeManagedResources)
{
Console.WriteLine(Name + ": FreeResources");
if (!ResourcesAreFreed)
{
// Dispose of managed resources if appropriate.
if (freeManagedResources)
{
// Dispose of managed resources here.
Console.WriteLine(Name + ": Dispose of managed resources");
}
// Dispose of unmanaged resources here.
Console.WriteLine(Name + ": Dispose of unmanaged resources");
// Remember that we have disposed of resources.
ResourcesAreFreed = true;
}
}
}
Create mysql connection with following parameter. "'raise_on_warnings': False". It will ignore the warning. e.g.
config = {'user': 'user','password': 'passwd','host': 'localhost','database': 'db', 'raise_on_warnings': False,}
cnx = mysql.connector.connect(**config)
In the controller action append to the header the following lines
public ActionResult Create(string PositionID)
{
Response.AppendHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.0.
Response.AppendHeader("Expires", "0"); // Proxies.
for ST3
$language = "language u wish"
if exists,
go to ~/.config/sublime-text-3/Packages/User/$language.sublime-settings
else
create ~/.config/sublime-text-3/Packages/User/$language.sublime-settings
and set
{ "extensions": [ "yourextension" ] }
This way allows you to enable syntax for composite extensions (e.g. sql.mustache, js.php, etc ... )

To attempt command line arguments directly is not possible.
One alternative might be environment variables (https://superuser.com/questions/728951/systemd-giving-my-service-multiple-arguments).
This is where I found the answer: http://www.freedesktop.org/software/systemd/man/systemctl.html
so sudo systemctl restart myprog -v

sudo systemctl restart myprog someotheroption
-- systemctl will restart myprog and the someotheroption service, if it exists.
You separate the values you want to return by commas:
def get_name():
# you code
return first_name, last_name
The commas indicate it's a tuple, so you could wrap your values by parentheses:
return (first_name, last_name)
Then when you call the function you a) save all values to one variable as a tuple, or b) separate your variable names by commas
name = get_name() # this is a tuple
first_name, last_name = get_name()
(first_name, last_name) = get_name() # You can put parentheses, but I find it ugly

a tip for people who needs the path/url in global.asax file;
If you need to run this in global.asax > Application_Start and you app pool mode is integrated then you will receive the error below:

In that case you need to use this:

Hope will help others..
try this:

for the center get the length of the string and do padleft and padright with the necessary characters
int len = "String goes here".Length;
int whites = len /2;
"String goes here".PadRight(len + whites,' ').PadLeft(len + whites,' ');
There are at least five different ways to rename specific columns in pandas, and I have listed them below along with links to the original answers. I also timed these methods and found them to perform about the same (though YMMV depending on your data set and scenario). The test case below is to rename columns A
M
N
Z
to A2
M2
N2
Z2
in a dataframe with columns A
to Z
containing a million rows.
# Import required modules
import numpy as np
import pandas as pd
import timeit
# Create sample data
df = pd.DataFrame(np.random.randint(0,9999,size=(1000000, 26)), columns=list('ABCDEFGHIJKLMNOPQRSTUVWXYZ'))
# Standard way - https://stackoverflow.com/a/19758398/452587
def method_1():
df_renamed = df.rename(columns={'A': 'A2', 'M': 'M2', 'N': 'N2', 'Z': 'Z2'})
# Lambda function - https://stackoverflow.com/a/16770353/452587
def method_2():
df_renamed = df.rename(columns=lambda x: x + '2' if x in ['A', 'M', 'N', 'Z'] else x)
# Mapping function - https://stackoverflow.com/a/19758398/452587
def rename_some(x):
if x=='A' or x=='M' or x=='N' or x=='Z':
return x + '2'
return x
def method_3():
df_renamed = df.rename(columns=rename_some)
# Dictionary comprehension - https://stackoverflow.com/a/58143182/452587
def method_4():
df_renamed = df.rename(columns={col: col + '2' for col in df.columns[
np.asarray([i for i, col in enumerate(df.columns) if 'A' in col or 'M' in col or 'N' in col or 'Z' in col])
]})
# Dictionary comprehension - https://stackoverflow.com/a/38101084/452587
def method_5():
df_renamed = df.rename(columns=dict(zip(df[['A', 'M', 'N', 'Z']], ['A2', 'M2', 'N2', 'Z2'])))
print('Method 1:', timeit.timeit(method_1, number=10))

Maybe a bit late, but I found this answer looking over the internet. It could help others with the same problem.
$sudo mysql -u root
[mysql] use mysql;
[mysql] update user set plugin='' where User='root';
[mysql] flush privileges;
[mysql] \q
Now you should be able to log in as root in phpmyadmin.
(Found here.)
Since there is only one global ServicePointManager, setting ServicePointManager.ServerCertificateValidationCallback will yield the result that all subsequent requests will inherit this policy. Since it is a global "setting" it would be prefered to set it in the Application_Start method in Global.asax.
Setting the callback overrides the default behaviour and you can yourself create a custom validation routine.

This question is ancient but..
Right after the opening body tag..
<!--[if gte IE 8]>
<div id="IE8Body">
<![endif]-->
Right before the closing body tag..
<!--[if gte IE 8]>
</div>
<![endif]-->
CSS..
#IE8Body #nav li ul {}
You could do this for all IE browsers using conditional statements, OR target ALL browsers by encapsulating all content in a div with browser name + version server-side
Vanilla Javascript:
this.querySelector(':checked').getAttribute('data-id')
MySQL socket is located, in general, in /tmp/mysql.sock
or /var/mysql/mysql.sock
, but probably PHP looks in the wrong place.
Check where is your socket with:
sudo /usr/libexec/locate.updatedb
When the updatedb is terminated:
locate mysql.sock
Then locate your php.ini:
php -i | grep php.ini
this will output something like:
Configuration File (php.ini) Path => /opt/local/etc/php54
Loaded Configuration File => /opt/local/etc/php54/php.ini
Edit your php.ini
sudo vim /opt/local/etc/php54/php.ini
Change the lines:
pdo_mysql.default_socket=/tmp/mysql.sock
mysql.default_socket=/tmp/mysql.sock
mysqli.default_socket = /tmp/mysql.sock
where /tmp/mysql.sock is the path to your socket.
Save your modifications and exit ESC + SHIFT: x
Restart Apache

Using a terminal command i.e. "clear", in a script called from cron (no terminal) will trigger this error message. In your particular script, the smbmount command expects a terminal in which case the work-arounds above are appropriate.
You can either use
request.original_url
or
"#{request.protocol}#{request.host_with_port}"
to get the current URL.
The first one is invalid syntax. You cannot have object properties inside a plain array. The second one is right although it is not strict JSON. It's a relaxed form of JSON wherein quotes in string keys are omitted.
This tutorial by Patrick Hunlock, may help to learn about JSON and this site may help to validate JSON.
The X-Frame-Options is defined in the Http Header and not in the <head>
section of the page you want to use in the iframe.
Accepted values are: DENY, SAMEORIGIN and ALLOW-FROM "url"
Using control-z suspends the process (see the output from stty -a
which lists the key stroke under susp
). That leaves it running, but in suspended animation (so it is not using any CPU resources). It can be resumed later.
If you want to stop a program permanently, then any of interrupt (often control-c) or quit (often control-\) will stop the process, the latter producing a core dump (unless you've disabled them). You might also use a HUP or TERM signal (or, if really necessary, the KILL signal, but try the other signals first) sent to the process from another terminal; or you could use control-z to suspend the process and then send the death threat from the current terminal, and then bring the (about to die) process back into the foreground (fg
).
Note that all key combinations are subject to change via the stty
command or equivalents; the defaults may vary from system to system.
I tried with "mMap.animateCamera( CameraUpdateFactory.zoomTo( 17.0f ) );" but it didn't work for me. So I used this animation for zooming in on start.
LatLng loc = new LatLng(33.8688, 151.2093);
mMap.addMarker(new MarkerOptions().position(loc).title("Sydney"));
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 18), 5000, null);
You can implement the Array.insert
method by doing this:
Array.prototype.insert = function ( index, item ) {
this.splice( index, 0, item );
};
Then you can use it like:
var arr = [ 'A', 'B', 'D', 'E' ];
arr.insert(2, 'C');
// => arr == [ 'A', 'B', 'C', 'D', 'E' ]
On modern computer systems, localhost as a hostname translates to an IPv4 address in the 127.0.0.0/8 (loopback) net block, usually 127.0.0.1, or ::1 in IPv6.
The only difference is that it would be looking up in the DNS for the system what localhost
resolves to. This lookup is really, really quick. For instance, to get to stackoverflow.com
you typed in that to the address bar (or used a bookmarklet that pointed here). Either way, you got here through a hostname. localhost
provides a similar functionality.
I could happen that if your array contains the string "hello", and if you are searching for "he", grep returns true, although, "he" may not be an array element.
Perhaps,
if (grep(/^$match$/, @array))
more apt.
If you want to build Java EE applications, it's best to use Eclipse IDE for Java EE. It has editors from HTML to JSP/JSF, Javascript. It's rich for webapps development, and provide plugins and tools to develop Java EE applications easily (all bundled).
Eclipse Classic is basically the full featured Eclipse without the Java EE part.
Even if your JSON is ok it could be DB charset (UTF8) problem. If your DB's charset/collation are UTF8 but PDO isn't set up properly (charset/workaround missing) some à / è / ò / ì / etc. in your DB could break your JSON encoding (still encoded but causing parsing issues). Check your connection string, it should be similar to one of these:
$pdo = new PDO('mysql:host=hostname;dbname=DBname;**charset=utf8**','username','password'); // PHP >= 5.3.6
$pdo = new PDO('mysql:host=hostname;dbname=DBname','username','password',**array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8")**); // older versions
P.S. Outdated but still could be helpful for people who're stuck with "unexpected character".
I had the same problem. Get the warning. Went to Data connections and deleted connection. Save, close reopen. Still get the warning. I use a xp/vista menu plugin for classic menus. I found under data, get external data, properties, uncheck the save query definition. Save close and reopen. That seemed to get rid of the warning. Just removing the connection does not work. You have to get rid of the query.
In android studio you can easily press:
android studio
, then press on app first.
Then, continue with step three as follows.You can also change the versionCode
of your app there.
With the verify
parameter you can provide a custom certificate authority bundle
requests.get(url, verify=path_to_bundle_file)
From the docs:
You can pass
verify
the path to a CA_BUNDLE file with certificates of trusted CAs. This list of trusted CAs can also be specified through the REQUESTS_CA_BUNDLE environment variable.
In your example
return $cnf::getConfig($key)
Probably should be:
return $cnf->getConfig($key)
And make getConfig not static
Always have easy way: Right Click > Generate > toString() > select template that you want.
I'd use this approach:
String randomString(final int length) {
Random r = new Random(); // perhaps make it a class variable so you don't make a new one every time
StringBuilder sb = new StringBuilder();
for(int i = 0; i < length; i++) {
char c = (char)(r.nextInt((int)(Character.MAX_VALUE)));
sb.append(c);
}
return sb.toString();
}
If you want a byte[] you can do this:
byte[] randomByteString(final int length) {
Random r = new Random();
byte[] result = new byte[length];
for(int i = 0; i < length; i++) {
result[i] = r.nextByte();
}
return result;
}
Or you could do this
byte[] randomByteString(final int length) {
Random r = new Random();
StringBuilder sb = new StringBuilder();
for(int i = 0; i < length; i++) {
char c = (char)(r.nextInt((int)(Character.MAX_VALUE)));
sb.append(c);
}
return sb.toString().getBytes();
}
With ANY operator you can search for only one value.
For example,
select * from mytable where 'Book' = ANY(pub_types);
If you want to search multiple values, you can use @> operator.
For example,
select * from mytable where pub_types @> '{"Journal", "Book"}';
You can specify in which ever order you like.
After compiling it you can jar it.
java -jar AppName.jar

A primitive long or its java.lang.Long wrapper can also store ten digits.
1) for example HTML code:
<ul>
<li>
<a href="#">firstlink</a>
<span><a href="#">second link</a>
</li>
</ul>
and css rules:
1) ul li a {color:red;}
2) ul > li > a {color:blue;}
">" - symbol mean that that will be searching only child selector (parentTag > childTag)
so first css rule will apply to all links (first and second) and second rule will apply anly to first link
2) As for efficiency - I think second will be more fast - as in case with JavaScript selectors. This rule read from right to left, this mean that when rule will parse by browser, it get all links on page: - in first case it will find all parent elements for each link on page and filter all links where exist parent tags "ul" and "li" - in second case it will check only parent node of link if it is "li" tag then -> check if parent tag of "li" is "ul"
some thing like this. Hope I describe all properly for you
There are two directories that looks like JDK.
C:\Program Files\Java\jdk1.7.0_02
C:\Program Files (x86)\Java\jdk1.7.0_02\
This may be due to both 64 bit and 32 bit JDK installed? What ever may be the case, the java.exe
seen by ant.bat should from the JDK. If the JRE's java.exe
comes first in the path, that will be used to guess the JDK location.
Put 'C:\Program Files (x86)\Java\jdk1.7.0_02\bin' or 'C:\Program Files\Java\jdk1.7.0_02' as the first argument in the path.
Further steps:
You can take output of ant -diagnostics
and look for interesting keys. (assuming Sun/Oracle JDK).
java.class.path
java.library.path
sun.boot.library.path
(in my case tools.jar appears in java.class.path)
I use this command.

Finally, I've defeated my CiSCO EAP-FAST corporate wifi network, and all our Android devices are now able to connect to it.
The walk-around I've performed in order to gain access to this kind of networks from an Android device are easiest than you can imagine.
There's a Wifi Config Editor in the Google Play Store you can use to "activate" the secondary CISCO Protocols when you are setting up a EAP wifi connection.
Its name is Wifi Config Advanced Editor.
First, you have to setup your wireless network manually as close as you can to your "official" corporate wifi parameters.
Save it.
Go to the WCE and edit the parameters of the network you have created in the previous step.
There are 3 or 4 series of settings you should activate in order to force the Android device to use them as a way to connect (the main site I think you want to visit is Enterprise Configuration, but don't forget to check all the parameters to change them if needed.
As a suggestion, even if you have a WPA2 EAP-FAST Cipher, try LEAP in your setup. It worked for me as a charm.
When you finished to edit the config, go to the main Android wifi controller, and force to connect to this network.
Do not Edit the network again with the Android wifi interface.
I have tested it on Samsung Galaxy 1 and 2, Note mobile devices, and on a Lenovo Thinkpad Tablet.

I was able to reduce my gradle build from 43 seconds down to 25 seconds on my old core2duo laptop (running linux mint) by adding the following to the gradle.properties file in android studio
org.gradle.parallel=true
org.gradle.daemon=true
source on why the daemon setting makes builds faster: https://www.timroes.de/2013/09/12/speed-up-gradle/
In general I fully agree with Jason's use of css selector, but in some cases you may not want to change the css, e.g. when using a 3rd party css-template, and rather prefer to add/remove a class on the element.
The following sample shows a simple way of adding/removing a class on ng-mouseenter/mouseleave:
<div ng-app>
<div
class="italic"
ng-class="{red: hover}"
ng-init="hover = false"
ng-mouseenter="hover = true"
ng-mouseleave="hover = false">
Test 1 2 3.
</div>
</div>
with some styling:
.red {
background-color: red;
}
.italic {
font-style: italic;
color: black;
}
See running example here: jsfiddle sample
Styling on hovering is a view concern. Although the solution above sets a "hover" property in the current scope, the controller does not need to be concerned about this.
Only the OR part is tricky, but with a general boolean expression containing NOT OR AND the only nice solution is this:
REM if A == B OR C == C then yes
(call :strequ A B || call :strequ C C) && echo yes
exit /b
:strequ
if "%1" == "%2" exit /b 0
exit /b 1
Maybe your mobile view port is not set.
Add following meta tag inside <head></head>
to allow menu to work on mobiles.
<meta name=viewport content="width=device-width, initial-scale=1">
You need to handle the MouseDown and MouseUp and set some flag or something to track it "later down the road"... :(
While the accepted solution works, it is not complete. By far.
If you want to get all the keys, you need to take into consideration 2 more things:
x86 & x64 applications do not have access to the same registry. Basically x86 cannot normally access x64 registry. And some applications only register to the x64 registry.
and
some applications actually install into the CurrentUser registry instead of the LocalMachine
With that in mind, I managed to get ALL installed applications using the following code, WITHOUT using WMI
Here is the code:
List<string> installs = new List<string>();
List<string> keys = new List<string>() {
@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall",
@"SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall"
};
// The RegistryView.Registry64 forces the application to open the registry as x64 even if the application is compiled as x86
FindInstalls(RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64), keys, installs);
FindInstalls(RegistryKey.OpenBaseKey(RegistryHive.CurrentUser, RegistryView.Registry64), keys, installs);
installs = installs.Where(s => !string.IsNullOrWhiteSpace(s)).Distinct().ToList();
installs.Sort(); // The list of ALL installed applications
private void FindInstalls(RegistryKey regKey, List<string> keys, List<string> installed)
{
foreach (string key in keys)
{
using (RegistryKey rk = regKey.OpenSubKey(key))
{
if (rk == null)
{
continue;
}
foreach (string skName in rk.GetSubKeyNames())
{
using (RegistryKey sk = rk.OpenSubKey(skName))
{
try
{
installed.Add(Convert.ToString(sk.GetValue("DisplayName")));
}
catch (Exception ex)
{ }
}
}
}
}
}

You can use something like this

</select>
</div>

in the settings.py of your project, check line 28, where is the Allows Host
settings.py
ALLOWED_HOSTS = ['IP', 'servidor', ]
you must put the IP and the server you use, level local or web settings.py
ALLOWED_HOSTS = ['127.0.0.1', 'localhost', 'www.ejemplo.com']
or
ALLOWED_HOSTS = ['*']
Sys.sleep() will not work if the CPU usage is very high; as in other critical high priority processes are running (in parallel).
This code worked for me. Here I am printing 1 to 1000 at a 2.5 second interval.
for (i in 1:1000)
{
print(i)
date_time<-Sys.time()
while((as.numeric(Sys.time()) - as.numeric(date_time))<2.5){} #dummy while loop
}
You must use a .ts
file - e.g. test.ts
to get Typescript validation, intellisense typing
of vars, return types, as well as "typed" error checking (e.g. passing a string
to a method that expects an number
param will error out).
It will be transpiled into (standard) .js
via tsc
.
Clarification needed based on down-votes, very helpful comments and other answers.
types
Yes, you can do type
checking in VS Code in .js
files with @ts-check
- as shown in the animation
What I originally was referring to for Typescript types
is something like this in .ts
which isn't quite the same thing:
hello-world.ts
function hello(str: string): string {
return 1;
}
function foo(str:string):void{
console.log(str);
}
This will not compile. Error: Type "1" is not assignable to String
if you tried this syntax in a Javascript hello-world.js
file:
//@ts-check
function hello(str: string): string {
return 1;
}
function foo(str:string):void{
console.log(str);
}
The error message referenced by OP is shown: [js] 'types' can only be used in a .ts file
If there's something I missed that covers this as well as the OP's context, please add. Let's all learn.
The same happened for me with eslint
module. EsLinter throw Parsing error: Invalid left-hand side in assignment expression
for await in second if statement.
if (condition_one) {
let result = await myFunction()
}
if (condition_two) {
let result = await myFunction() // eslint parsing error
}
As strange as it sounds what fixed this error was to add ; semicolon at the end of line where await occurred.
if (condition_one) {
let result = await myFunction();
}
if (condition_two) {
let result = await myFunction();
}
I've been looking for a good way to use javascript to initiate the download of a file, just as this question suggests. However these answers not been helpful. I then did some xbrowser testing and have found that an iframe works best on all modern browsers IE>8.
downloadUrl = "http://example.com/download/file.zip";
var downloadFrame = document.createElement("iframe");
downloadFrame.setAttribute('src',downloadUrl);
downloadFrame.setAttribute('class',"screenReaderText");
document.body.appendChild(downloadFrame);
class="screenReaderText"
is my class to style content that is present but not viewable.
css:
.screenReaderText {
border: 0;
clip: rect(0 0 0 0);
height: 1px;
margin: -1px;
overflow: hidden;
padding: 0;
position: absolute;
width: 1px;
}
same as .visuallyHidden in html5boilerplate
I prefer this to the javascript window.open method because if the link is broken the iframe method simply doesn't do anything as opposed to redirecting to a blank page saying the file could not be opened.
window.open(downloadUrl, 'download_window', 'toolbar=0,location=no,directories=0,status=0,scrollbars=0,resizeable=0,width=1,height=1,top=0,left=0');
window.focus();
