You have to specify that test1 is global:
test1 = 0
def testFunc():
global test1
test1 += 1
testFunc()
I know this question is too old, but still, I think this approach would be cleaner:
cat = $.URLDecode(cat);
$('#cbCategory option:contains("' + cat + '")').prop('selected', true);
In this case you wont need to go over the entire options with each()
.
Although by that time prop()
didn't exist so for older versions of jQuery use attr()
.
UPDATE
You have to be certain when using contains
because you can find multiple options, in case of the string inside cat
matches a substring of a different option than the one you intend to match.
Then you should use:
cat = $.URLDecode(cat);
$('#cbCategory option')
.filter(function(index) { return $(this).text() === cat; })
.prop('selected', true);
I would just do:
private static Timer timer;
private static void Main()
{
timer = new Timer(_ => OnCallBack(), null, 1000 * 10,Timeout.Infinite); //in 10 seconds
Console.ReadLine();
}
private static void OnCallBack()
{
timer.Dispose();
Thread.Sleep(3000); //doing some long operation
timer = new Timer(_ => OnCallBack(), null, 1000 * 10,Timeout.Infinite); //in 10 seconds
}
And ignore the period parameter, since you're attempting to control the periodicy yourself.
Your original code is running as fast as possible, since you keep specifying 0
for the dueTime
parameter. From Timer.Change
:
If dueTime is zero (0), the callback method is invoked immediately.
The WHERE
clause is evaluated after the JOIN
conditions have been processed.
You can do this:-
$('#about-link').addClass('current');
$('#menu li a').on('click', function(e){
e.preventDefault();
$('#menu li a.current').removeClass('current');
$(this).addClass('current');
});
Demo: Fiddle
The same error appears if you do not use the correct (numeric) format of your data in your data.frame column using mean()
function. Therefore, check your data using str(data.frame&column)
function to see what data type you have, and convert it to numeric format if necessary.
For example, if your data is Character convert it with as.numeric(data.frame$column)
, or as a factor with as.numeric(as.character(data.frame$column))
. The mean function does not work with types other than numeric.
Path Variables dialog has nothing to do with the environment variables.
Environment variables can be specified in your OS or customized in the Run configuration:
Check out -webkit-appearance: none and its derivatives. Originally described by Chris Coyer here: https://css-tricks.com/almanac/properties/a/appearance/
You can use Data URIs.
For example:
data:text/html,<script>alert('hi');</script>

There is an alternative for creating an iframe whose contents are a string of HTML: the srcdoc attribute. This is not supported in older browsers (chief among them: Internet Explorer, and possibly Safari?), but there is a polyfill for this behavior, which you could put in conditional comments for IE, or use something like has.js to conditionally lazy load it.
As everybody above has explained about the difference between binary tree and binary search tree, i am just adding how to test whether the given binary tree is binary search tree.
boolean b = new Sample().isBinarySearchTree(n1, Integer.MIN_VALUE, Integer.MAX_VALUE);
.......
.......
.......
public boolean isBinarySearchTree(TreeNode node, int min, int max)
{
if(node == null)
{
return true;
}
boolean left = isBinarySearchTree(node.getLeft(), min, node.getValue());
boolean right = isBinarySearchTree(node.getRight(), node.getValue(), max);
return left && right && (node.getValue()<max) && (node.getValue()>=min);
}
Hope it will help you. Sorry if i am diverting from the topic as i felt it's worth mentioning this here.
Add this code in your Activity
@Override
public void onBackPressed() {
if (getFragmentManager().getBackStackEntryCount() == 0) {
super.onBackPressed();
} else {
getFragmentManager().popBackStack();
}
}
And add this line in your Fragment before commit()
ft.addToBackStack("Any name");
FIRST U NEED TO DEFINE WHAT'S A GET VAR:
function getVar()
{
this.length = 0;
this.keys = [];
this.push = function(key, value)
{
if(key=="") key = this.length++;
this[key] = value;
this.keys.push(key);
return this[key];
}
}
Than just read:
function urlElement()
{
var thisPrototype = window.location;
for(var prototypeI in thisPrototype) this[prototypeI] = thisPrototype[prototypeI];
this.Variables = new getVar();
if(!this.search) return this;
var variables = this.search.replace(/\?/g,'').split('&');
for(var varI=0; varI<variables.length; varI++)
{
var nameval = variables[varI].split('=');
var name = nameval[0].replace(/\]/g,'').split('[');
var pVariable = this.Variables;
for(var nameI=0;nameI<name.length;nameI++)
{
if(name.length-1==nameI) pVariable.push(name[nameI],nameval[1]);
else var pVariable = (typeof pVariable[name[nameI]] != 'object')? pVariable.push(name[nameI],new getVar()) : pVariable[name[nameI]];
}
}
}
and use like:
var mlocation = new urlElement();
mlocation = mlocation.Variables;
for(var key=0;key<mlocation.keys.length;key++)
{
console.log(key);
console.log(mlocation[mlocation.keys[key]];
}
Easy method that works with Ruby version >= 2.0 but not with older versions :

irb(main):002:0> c=[5,6]
=> [5, 6]
irb(main):004:0> [*a,*b,*c]
=> [1, 2, 3, 4, 5, 6]

Probably won't help but you could try creating a CSV table with that content:
DROP TABLE IF EXISTS foo_export;
CREATE TABLE foo_export LIKE foo;
ALTER TABLE foo_export ENGINE=CSV;
INSERT INTO foo_export SELECT id,
client,
project,
task,
REPLACE(REPLACE(ifnull(ts.description,''),'\n',' '),'\r',' ') AS description,
time,
date

It seems that
{
"start_windows": "set NODE_ENV=test"
}
is not working for me. I'm currently trying this on my Windows machine. When I hit:
npm run start_windows
it would execute on the console without errors but when I try to echo
echo %NODE_ENV%
nothing comes out of it, meaning it does not exist and it wasn't set at all...
It's Carriage Return
. Source: http://msdn.microsoft.com/en-us/library/6aw8xdf2(v=vs.80).aspx
The following repeats the loop until the user has pressed the Return key.
while(ch!='\r')
{
ch=getche();
}
Just for completion, here is a code example indicating the differences:
success \ error:
$http.get('/someURL')
.success(function(data, status, header, config) {
// success handler
})
.error(function(data, status, header, config) {
// error handler
});
then:
$http.get('/someURL')
.then(function(response) {
// success handler
}, function(response) {
// error handler
})
.then(function(response) {
// success handler
}, function(response) {
// error handler
})
.then(function(response) {
// success handler
}, function(response) {
// error handler
}).
Guava has a method Ints.asList()
for creating a List<Integer>
backed by an int[]
array. You can use this with Collections.sort to apply the Comparator to the underlying array.
List<Integer> integersList = Ints.asList(arr);
Collections.sort(integersList, Collections.reverseOrder());
Note that the latter is a live list backed by the actual array, so it should be pretty efficient.
I've always understood that the below will give me the fastest response times.

If you want a specific version:
Install-Package System.Configuration.ConfigurationManager -Version 4.5.0
Your ConfigurationManager

When you install python for windows, there is an option to include it in the path. For python 2 this is not the default. It adds the python installation folder and script folder to the Windows path. When starting the GIT Bash command prompt, it have included it in the linux PATH variable.
If you start the python installation again, you should select the option Change python and in the next step you can "Add python.exe to Path". Next time you open GIT Bash, the path is correct.
Picking up on bta's lookup table idea, you can create the lookup table with a block. Values get generated when they are first accessed and stored for later:
>> lookup_table = Hash.new { |h, i| h[i] = i.to_s(2) }
=> {}
>> lookup_table[1]
=> "1"
>> lookup_table[2]
=> "10"
>> lookup_table[20]
=> "10100"
>> lookup_table[200]
=> "11001000"
>> lookup_table
=> {1=>"1", 200=>"11001000", 2=>"10", 20=>"10100"}
Hey I got the solution. I did not set the category as "Default". Also I was using the Main activity for the intent Data. Now i am using a different activity for the intent data. Thanks for the help. :)
The dword ptr
part is called a size directive. This page explains them, but it wasn't possible to direct-link to the correct section.
Basically, it means "the size of the target operand is 32 bits", so this will bitwise-AND the 32-bit value at the address computed by taking the contents of the ebp
register and subtracting four with 0.
EDIT: According to the comments on the original post this is a C# question.
Short answer: yes, using the this

Long answer: yes, using the this
keyword, and here's an example.

public MyClass(object data)
{
this.someData = data;
}
public MyClass() : this(new object())
{
// Calls the previous constructor with a new object,
// setting someData to that object
}
}

From git-blame:
Annotates each line in the given file with information from the revision which last modified the line. Optionally, start annotating from the given revision.
When specified one or more times, -L restricts annotation to the requested lines.
Example:
[email protected]:~# git blame .htaccess
...
^e1fb2d7 (John Doe 2015-07-03 06:30:25 -0300 4) allow from all
^72fgsdl (Arthur King 2015-07-03 06:34:12 -0300 5)
^e1fb2d7 (John Doe 2015-07-03 06:30:25 -0300 6) <IfModule mod_rewrite.c>
^72fgsdl (Arthur King 2015-07-03 06:34:12 -0300 7) RewriteEngine On
...
Please note that git blame
does not show the per-line modifications history in the chronological sense.
It only shows who was the last person to have changed a line in a document up to the last commit in HEAD
.
That is to say that in order to see the full history/log of a document line, you would need to run a git blame path/to/file
for each commit in your git log
.

This question was linked from Multiline JLabels - Java.
The function itself is valid matlab-code. The problem must be something else.
Try calling the function from within the directory it is located or add that directory to your searchpath using addpath('pathname')
.
It looks as though the horizontal axis (Category Group) labels have very long values - there may not be room to display them all. I suggest changing the labels to have shorter values.
You can set the sort order for the Category Groups in the Category Group Properties - Sorting section - this may have been previously set; if not, I suggest using this to sort as desired.
Thanx @krd, I am using your error catch process, but had to update the print and except statements. I am using Python 2.7.6 on Linux Mint 17.2.
Also, it was unclear where the output string was coming from. My update:
import subprocess
# Output returned in error handler
try:
print("Ping stdout output on success:\n" +
subprocess.check_output(["ping", "-c", "2", "-w", "2", "1.1.1.1"]))
except subprocess.CalledProcessError as e:
print("Ping stdout output on error:\n" + e.output)
# Output returned normally
try:
print("Ping stdout output on success:\n" +
subprocess.check_output(["ping", "-c", "2", "-w", "2", "8.8.8.8"]))
except subprocess.CalledProcessError as e:
print("Ping stdout output on error:\n" + e.output)
I see an output like this:
Ping stdout output on error:

--- 1.1.1.1 ping statistics ---
2 packets transmitted, 0 received, 100% packet loss, time 1007ms

Here is a complete jquery plugin that solves this problem:
https://github.com/bigspotteddog/ScrollToFixed
The description of this plugin is as follows:
This plugin is used to fix elements to the top of the page, if the element would have scrolled out of view, vertically; however, it does allow the element to continue to move left or right with the horizontal scroll.
Given an option marginTop, the element will stop moving vertically upward once the vertical scroll has reached the target position; but, the element will still move horizontally as the page is scrolled left or right. Once the page has been scrolled back down past the target position, the element will be restored to its original position on the page.
This plugin has been tested in Firefox 3/4, Google Chrome 10/11, Safari 5, and Internet Explorer 8/9.
Usage for your particular case:
<script src="scripts/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="scripts/jquery-scrolltofixed-min.js" type="text/javascript"></script>
$(document).ready(function() {
$('#mydiv').scrollToFixed({ marginTop: 250 });
});
Your where clause should have worked. I am at a loss as to why it didn't. Let me show you how I would have figured out the problem with the where clause as it might help you for the future.
When I create triggers, I start at the query window by creating a temp table called #inserted (and or #deleted) with all the columns of the table. Then I popultae it with typical values (Always multiple records and I try to hit the test cases in the values)
Then I write my triggers logic and I can test without it actually being in a trigger. In a case like your where clause not doing what was expected, I could easily test by commenting out the insert to see what the select was returning. I would then probably be easily able to see what the problem was. I assure you that where clasues do work in triggers if they are written correctly.
Once I know that the code works properly for all the cases, I global replace #inserted with inserted and add the create trigger code around it and voila, a tested trigger.
AS I said in a comment, I have a concern that the solution you picked will not work properly in a multiple record insert or update. Triggers should always be written to account for that as you cannot predict if and when they will happen (and they do happen eventually to pretty much every table.)
This is probably the closest translation from your C code to Python code.
A = 1
B = "hello"
buf = "A = %d\n , B= %s\n" % (A, B)
c = 2
buf += "C=%d\n" % c
f = open('output.txt', 'w')
print >> f, c
f.close()
The %
operator in Python does almost exactly the same thing as C's sprintf
. You can also print the string to a file directly. If there are lots of these string formatted stringlets involved, it might be wise to use a StringIO
object to speed up processing time.
So instead of doing +=
, do this:
import cStringIO
buf = cStringIO.StringIO()
...
print >> buf, "A = %d\n , B= %s\n" % (A, B)
...
print >> buf, "C=%d\n" % c
...
print >> f, buf.getvalue()
You can use this code:
// Create an array that matches any country to its id (as String):
String[][] countriesId = new String[NUMBER_OF_COUNTRIES_SUPPORTED][];
// Initialize the array, where the first column will be the country's name (in uppercase) and the second column will be its id (as String):
countriesId[0] = new String[] {"US", String.valueOf(R.drawable.us)};
countriesId[1] = new String[] {"FR", String.valueOf(R.drawable.fr)};
// and so on...
// And after you get the variable "countryCode":
int i;
for(i = 0; i<countriesId.length; i++) {
if(countriesId[i][0].equals(countryCode))
break;
}
// Now "i" is the index of the country
img.setImageResource(Integer.parseInt(countriesId[i][1]));
Create extra table with same header as the main table. Just put thead in the new table with one row and all the headers in it. Do position absolute and background white. For main table put it in a div and use some height and overflow-y scroll. This way our new table will overcome the header of main table and stay there. Surround everything in a div. Below is the rough code to do it.
<div class="col-sm-8">
<table id="header-fixed" class="table table-bordered table-hover" style="width: 351px;position: absolute;background: white;">
<thead>
<tr>
<th>Col1</th>
<th>Col2</th>
<th>Col3</th>
</tr>
</thead>
</table>
<div style="height: 300px;overflow-y: scroll;">
<table id="tableMain" class="table table-bordered table-hover" style="table-layout:fixed;overflow-wrap: break-word;cursor:pointer">
<thead>
<tr>
<th>Col1</th>
<th>Col2</th>
<th>Col3</th>
</tr>
</thead>
<tbody>
<tr>
<td>info</td>
<td>info</td>
<td>info</td>
</tr>
<tr>
<td>info</td>
<td>info</td>
<td>info</td>
</tr>
<tr>
<td>info</td>
<td>info</td>
<td>info</td>
</tr>
</tbody>
</table>
</div>
</div>
Are you putting this line inside the class declaration? In that case you should remove the JSONDeserializer::
.
As others have said, it's a direct child, but it's worth noting that this is different to just leaving a space... a space is for any descendant.
<div>
<span>Some text</span>
</div>
div>span
would match this, but it would not match this:
<div>
<p><span>Some text</span></p>
</div>
To match that, you could do div>p>span
or div span
.

jQuery isn't particularly helpful for sorting, but here's an elegant and efficient solution. Just write a plain JS function that takes the property name and the order (ascending or descending) and calls the native sort() method with a simple comparison function:
var people = [
{
"f_name": "john",
"l_name": "doe",
"sequence": "0",
"title" : "president",
"url" : "google.com",
"color" : "333333",
}
// etc
];
function sortResults(prop, asc) {
people.sort(function(a, b) {
if (asc) {
return (a[prop] > b[prop]) ? 1 : ((a[prop] < b[prop]) ? -1 : 0);
} else {
return (b[prop] > a[prop]) ? 1 : ((b[prop] < a[prop]) ? -1 : 0);
}
});
renderResults();
}
Then:
sortResults('l_name', true);
Play with a working example here.
I had the same problem and nothing mentioned here worked for me. Here is what worked for me:
main.js
file that is run by electron. (this seemed to be the first important part for me)npm i -D electron-rebuild
to add the electron-rebuild packagenode-modules
folder, as well as the packages-lock.json
file.npm i
to install all modules../node_modules/.bin/electron-rebuild
(.\node_modules\.bin\electron-rebuild.cmd
for Windows) to rebuild everythingIt is very important to run ./node_modules/.bin/electron-rebuild
directly after npm i
otherwise it did not work on my mac.
I hope I could help some frustrated souls.
You'll need two slightly different conversions.
To convert from Time
to DateTime
you can amend the Time class as follows:
require 'date'
class Time
def to_datetime
# Convert seconds + microseconds into a fractional number of seconds
seconds = sec + Rational(usec, 10**6)
# Convert a UTC offset measured in minutes to one measured in a
# fraction of a day.
offset = Rational(utc_offset, 60 * 60 * 24)
DateTime.new(year, month, day, hour, min, seconds, offset)
end
end
Similar adjustments to Date will let you convert DateTime
to Time
.
class Date
def to_gm_time
to_time(new_offset, :gm)
end
def to_local_time
to_time(new_offset(DateTime.now.offset-offset), :local)
end
private
def to_time(dest, method)
#Convert a fraction of a day to a number of microseconds
usec = (dest.sec_fraction * 60 * 60 * 24 * (10**6)).to_i
Time.send(method, dest.year, dest.month, dest.day, dest.hour, dest.min,
dest.sec, usec)
end
end
Note that you have to choose between local time and GM/UTC time.
Both the above code snippets are taken from O'Reilly's Ruby Cookbook. Their code reuse policy permits this.
You can use Instance.ToShortDateString() for the date,
and Instance.ToShortTimeString() for the time to get date and time from the same instance.
You can also do this without using groupby or loc. By simply including the condition in code. Let the name of dataframe be df. Then you can try :
df[df['a']==1]['b'].sum()
or you can also try :
sum(df[df['a']==1]['b'])
Another way could be to use the numpy library of python :
import numpy as np
print(np.where(df['a']==1, df['b'],0).sum())
Wonderful answer! I needed to fill in the empty cells in a column where there were titles in cells that applied to the empty cells below until the next title cell.
I used your code above to develop the code that is below my example sheet here. I applied this code as a macro ctl/shft/D to rapidly run down the column copying the titles.
--- Example Spreadsheet ------------ Title1 is copied to rows 2 and 3; Title2 is copied to cells below it in rows 5 and 6. After the second run of the Macro the active cell is the Title3 cell.
' **row** **Column1** **Column2**
' 1 Title1 Data 1 for title 1
' 2 Data 2 for title 1
' 3 Data 3 for title 1
' 4 Title2 Data 1 for title 2
' 5 Data 2 for title 2
' 6 Data 3 for title 2
' 7 Title 3 Data 1 for title 3
----- CopyDown code ----------
Sub CopyDown()
Dim Lastrow As String, FirstRow As String, strtCell As Range
'
' CopyDown Macro
' Copies the current cell to any empty cells below it.
'
' Keyboard Shortcut: Ctrl+Shift+D
'
Set strtCell = ActiveCell
FirstRow = strtCell.Address
' Lastrow is address of the *list* of empty cells
Lastrow = Range(Selection, Selection.End(xlDown).Offset(-1, 0)).Address
' MsgBox Lastrow
Range(Lastrow).Formula = strtCell.Formula
Range(Lastrow).End(xlDown).Select
End Sub

Using BeautifulSoup the easiest way with less code to just get the strings, without empty lines and crap.
tag = <Parent_Tag_that_contains_the_data>
soup = BeautifulSoup(tag, 'html.parser')
for i in soup.stripped_strings:
print repr(i)
I didn't understand this pattern until I came across with uncle bob article and read comments. Consider the following code:
public class Employee
{
}
public class SalariedEmployee : Employee
{
}
public class HourlyEmployee : Employee
{
}
public class QtdHoursAndPayReport
{
public void PrintReport()
{
var employees = new List<Employee>
{
new SalariedEmployee(),
new HourlyEmployee()
};
foreach (Employee e in employees)
{
if (e is HourlyEmployee he)
PrintReportLine(he);
if (e is SalariedEmployee se)
PrintReportLine(se);
}
}
public void PrintReportLine(HourlyEmployee he)
{
System.Diagnostics.Debug.WriteLine("hours");
}
public void PrintReportLine(SalariedEmployee se)
{
System.Diagnostics.Debug.WriteLine("fix");
}
}
class Program
{
static void Main(string[] args)
{
new QtdHoursAndPayReport().PrintReport();
}
}
While it may look good since it confirms to Single Responsibility it violates Open/Closed principle. Each time you have new Employee type you will have to add if with type check. And if you won't you'll never know that at compile time.
With visitor pattern you can make your code cleaner since it does not violate open/closed principle and does not violate Single responsibility. And if you forget to implement visit it won't compile:
public abstract class Employee
{
public abstract void Accept(EmployeeVisitor v);
}
public class SalariedEmployee : Employee
{
public override void Accept(EmployeeVisitor v)

The magic is that while v.Visit(this)
looks the same it's in fact different since it call different overloads of visitor.

Provided that you are extending JFrame:
public void run() {
MyFrame myFrame = new MyFrame();
myFrame.setVisible(true);
myFrame.setExtendedState(myFrame.getExtendedState() | JFrame.MAXIMIZED_BOTH);
}
string text = "Retrieves a substring from this instance. The substring starts at a specified character position. Some other text";
string result = text.Substring(text.IndexOf('.') + 1,text.LastIndexOf('.')-text.IndexOf('.'))
This will cut the part of string which lays between the special characters.
select date_format(date_parse(t.payDate,'%Y-%m-%d %H:%i:%S'),'%Y-%m-%d') as payDate
from testTable t
where t.paydate is not null and t.paydate <> '';
For whatever reason, the Scanner class also issues this same exception if it encounters special characters it cannot read. Beyond using the hasNextLine()
method before each call to nextLine()
, make sure the correct encoding is passed to the Scanner
constructor, e.g.:
Scanner scanner = new Scanner(new FileInputStream(filePath), "UTF-8");
http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.remoteendpoint.aspx
You can then call the IPEndPoint..::.Address method to retrieve the remote IPAddress, and the IPEndPoint..::.Port method to retrieve the remote port number.
More from the link (fixed up alot heh):
Socket s;
IPEndPoint remoteIpEndPoint = s.RemoteEndPoint as IPEndPoint;
IPEndPoint localIpEndPoint = s.LocalEndPoint as IPEndPoint;
if (remoteIpEndPoint != null)
{
// Using the RemoteEndPoint property.
Console.WriteLine("I am connected to " + remoteIpEndPoint.Address + "on port number " + remoteIpEndPoint.Port);
}
if (localIpEndPoint != null)
{
// Using the LocalEndPoint property.
Console.WriteLine("My local IpAddress is :" + localIpEndPoint.Address + "I am connected on port number " + localIpEndPoint.Port);
}
This code makes a window with the conditions that the user cannot change the dimensions of the Tk()
window, and also disables the maximise button.
import tkinter as tk
root = tk.Tk()
root.resizable(width=False, height=False)
root.mainloop()
Within the program you can change the window dimensions with @Carpetsmoker's answer, or by doing this:
root.geometry('{}x{}'.format(<widthpixels>, <heightpixels>))
It should be fairly easy for you to implement that into your code. :)
Plain and simple, to fetch the submodules:
git submodule update --init --recursive
And now proceed updating them to the latest master branch (for example):
git submodule foreach git pull origin master

In VC# Express
, this property is missing, but you can still create an x86 configuration if you know where to look.
It looks like a long list of steps, but once you know where these things are it's a lot easier. Anyone who only has VC# Express
will probably find this useful. Once you know about Configuration Manager
, it'll be much more intuitive the next time.
1.In VC# Express 2005, go to Tools -> Options
.
2.In the bottom-left corner of the Options dialog, check the box that says, "Show all settings"
.
3.In the tree-view on the left hand side, select "Projects and Solutions"
.
4.In the options on the right, check the box that says, "Show advanced build configuraions."
5.Click OK
.
6.Go to Build -> Configuration Manager
...
7.In the Platform column next to your project, click the combobox and select "<New...>"
.
8.In the "New platform" setting, choose "x86"
.
9.Click OK
.
10.Click Close
.
There, now you have an x86 configuration! Easy as pie! :-)
I also recommend using Configuration Manager
to delete the Any CPU platform. You really don't want that if you ever have depedencies on 32-bit native DLLs (even indirect dependencies).

The script I use is quite similar; I post it here as an example of how to use the email.* modules to generate MIME messages; so this script can be easily modified to attach pictures, etc.
I rely on my ISP to add the date time header.
My ISP requires me to use a secure smtp connection to send mail, I rely on the smtplib module (downloadable at http://www1.cs.columbia.edu/~db2501/ssmtplib.py)
As in your script, the username and password, (given dummy values below), used to authenticate on the SMTP server, are in plain text in the source. This is a security weakness; but the best alternative depends on how careful you need (want?) to be about protecting these.
=======================================
#! /usr/local/bin/python
SMTPserver = 'smtp.att.yahoo.com'
sender = 'me@my_email_domain.net'
destination = ['recipient@her_email_domain.com']
USERNAME = "USER_NAME_FOR_INTERNET_SERVICE_PROVIDER"
PASSWORD = "PASSWORD_INTERNET_SERVICE_PROVIDER"
# typical values for text_subtype are plain, html, xml
text_subtype = 'plain'
content="""\
Test message
"""
subject="Sent from Python"
import sys
import os
import re
from smtplib import SMTP_SSL as SMTP # this invokes the secure SMTP protocol (port 465, uses SSL)
# from smtplib import SMTP # use this for standard SMTP protocol (port 25, no encryption)
# old version
# from email.MIMEText import MIMEText
from email.mime.text import MIMEText
try:
msg = MIMEText(content, text_subtype)
msg['Subject']= subject
msg['From'] = sender # some SMTP servers will do this automatically, not all
conn = SMTP(SMTPserver)
conn.set_debuglevel(False)
conn.login(USERNAME, PASSWORD)
try:
conn.sendmail(sender, destination, msg.as_string())
finally:
conn.quit()
except:
sys.exit( "mail failed; %s" % "CUSTOM_ERROR" ) # give an error message
You can do in this way:
Integer i = 1;
new BigInteger("" + i);
Personnaly I encountered this issue while migrating a IIS6 website into IIS7, in order to fix this issue I used this command line :
%windir%\System32\inetsrv\appcmd migrate config "MyWebSite\"
Make sure to backup your web.config
Your solution is here but instead of addition you need to use subtraction
c.add(Calendar.MONTH, -1);
Then you can call getter on the Calendar
to acquire proper fields
int month = c.get(Calendar.MONTH) + 1; // beware of month indexing from zero
int year = c.get(Calendar.YEAR);
You're comparing the message with the empty string using ==
.
First, your comparison is wrong because the message will be null (and not the empty string).
Second, it's wrong because Objects must be compared with equals()
and not with ==
.
Third, it's wrong because you should avoid scriptlets in JSP, and use the JSP EL, the JSTL, and other custom tags instead:
<c:id test="${!empty message}">
<c:out value="${message}"/>
</c:if>
Object.keys(myObj).length === 0;
As there is need to just check if Object is empty it will be better to directly call a native method Object.keys(myObj).length which returns the array of keys by internally iterating with for..in loop.As Object.hasOwnProperty
returns a boolean result based on the property present in an object which itself iterates with for..in loop and will have time complexity O(N2).
On the other hand calling a UDF which itself has above two implementations or other will work fine for small object but will block the code which will have severe impact on overall perormance if Object size is large unless nothing else is waiting in the event loop.
Looks like the solution is to set the value of the properties inside the default constructor. So in this case the java class is:
class JavaObject {
public JavaObject() {
optionalMember = "Value";
}
@NotNull
public String notNullMember;
public String optionalMember;
}
After the mapping with Jackson, if the optionalMember
is missing from the JSON its value in the Java class is "Value"
.
However, I am still interested to know if there is a solution with annotations and without the default constructor.
Most problems can be solved using (i) just locks, (ii) just semaphores, ..., or (iii) a combination of both! As you may have discovered, they're very similar: both prevent race conditions, both have acquire()
/release()
operations, both cause zero or more threads to become blocked/suspected...
Really, the crucial difference lies solely on how they lock and unlock.
For both locks/semaphores, trying to call acquire()
while the primitive is in state 0 causes the invoking thread to be suspended. For locks - attempts to acquire the lock is in state 1 are successful. For semaphores - attempts to acquire the lock in states {1, 2, 3, ...} are successful.
For locks in state state 0, if same thread that had previously called acquire()
, now calls release, then the release is successful. If a different thread tried this -- it is down to the implementation/library as to what happens (usually the attempt ignored or an error is thrown). For semaphores in state 0, any thread can call release and it will be successful (regardless of which thread previous used acquire to put the semaphore in state 0).
From the preceding discussion, we can see that locks have a notion of an owner (the sole thread that can call release is the owner), whereas semaphores do not have an owner (any thread can call release on a semaphore).
What causes a lot of confusion is that, in practice they are many variations of this high-level definition.
Important variations to consider:
acquire()
/release()
be called? -- [Varies massively]These depends on your book / lecturer / language / library / environment.
Here's a quick tour noting how some languages answer these details.
pthread_mutex_t
. By default, they can't be shared with any other processes (PTHREAD_PROCESS_PRIVATE
), however mutex's have an attribute called pshared. When set, so the mutex is shared between processes (PTHREAD_PROCESS_SHARED
). sem_t
. Similar to mutexes, semaphores can be shared between threasds of many processes or kept private to the threads of one single process. This depends on the pshared argument provided to sem_init
. threading.RLock
) is mostly the same as C/C++ pthread_mutex_t
s. Both are both reentrant. This means they may only be unlocked by the same thread that locked it. It is the case that sem_t
semaphores, threading.Semaphore
semaphores and theading.Lock
locks are not reentrant -- for it is the case any thread can perform unlock the lock / down the semaphore.threading.Semaphore
) is mostly the same as sem_t
. Although with sem_t
, a queue of thread ids is used to remember the order in which threads became blocked when attempting to lock it while it is locked. When a thread unlocks a semaphore, the first thread in the queue (if there is one) is chosen to be the new owner. The thread identifier is taken off the queue and the semaphore becomes locked again. However, with threading.Semaphore
, a set is used instead of a queue, so the order in which threads became blocked is not stored -- any thread in the set may be chosen to be the next owner.java.util.concurrent.ReentrantLock
) is mostly the same as C/C++ pthread_mutex_t
's, and Python's threading.RLock
in that it also implements a reentrant lock. Sharing locks between processes is harder in Java because of the JVM acting as an intermediary. If a thread tries to unlock a lock it doesn't own, an IllegalMonitorStateException
is thrown.java.util.concurrent.Semaphore
) is mostly the same as sem_t
and threading.Semaphore
. The constructor for Java semaphores accept a fairness boolean parameter that control whether to use a set (false) or a queue (true) for storing the waiting threads. In theory, semaphores are often discussed, but in practice, semaphores aren't used so much. A semaphore only hold the state of one integer, so often it's rather inflexible and many are needed at once -- causing difficulty in understanding code. Also, the fact that any thread can release a semaphore is sometimes undesired. More object-oriented / higher-level synchronization primitives / abstractions such as "condition variables" and "monitors" are used instead.
You can use do.call:
do.call("<-",list(parameter_name, parameter_value))
If you have a List of type string that you want in a drop down list I do the following:
EDIT: Clarified, making it a fuller example.
public class ShipDirectory
{
public string ShipDirectoryName { get; set; }
public List<string> ShipNames { get; set; }
}
ShipDirectory myShipDirectory = new ShipDirectory()
{
ShipDirectoryName = "Incomming Vessels",
ShipNames = new List<string>(){"A", "A B"},
}
myShipDirectory.ShipNames.Add("Aunt Bessy");
@Html.DropDownListFor(x => x.ShipNames, new SelectList(Model.ShipNames), "Select a Ship...", new { @style = "width:500px" })
Which gives a drop down list like so:
<select id="ShipNames" name="ShipNames" style="width:500px">
<option value="">Select a Ship...</option>
<option>A</option>
<option>A B</option>
<option>Aunt Bessy</option>
</select>
To get the value on a controllers post; if you are using a model (e.g. MyViewModel) that has the List of strings as a property, because you have specified x => x.ShipNames you simply have the method signature as (because it will be serialised/deserialsed within the model):
public ActionResult MyActionName(MyViewModel model)
Access the ShipNames value like so: model.ShipNames
If you just want to access the drop down list on post then the signature becomes:
public ActionResult MyActionName(string ShipNames)
EDIT: In accordance with comments have clarified how to access the ShipNames property in the model collection parameter.
I like to write a small plugin to make things cleaner:
$.fn.setClass = function(classes) {
this.attr('class', classes);
return this;
};
That way you can simply do
$('button').setClass('btn btn-primary');
This is an old question, and there are many answers, most of which will be more or less helpful; however, there is one, very important and still relevant point, which none of the answers touch (providing, instead, different hacks to make build possible), and which, I think, in no way has a less importance.. on the contrary.
According to your log message, you are using Maven, which is a Project Management tool, firmly following the conventions, over configuration principle.
When Maven builds the project:
Maven's Standard Directory Layout
;Sun Microsystems Directory Structure Standard
for Java EE [web] applications.You may incorporate many things, including maven plugins, changing/reconfiguring project root directory, etc., but better and easier is to follow the default conventions over configuration, according to which, (now is the answer to your problem) there is one simple step that can make your project work: Just place your web.xml
under src\main\webapp\WEB-INF\
and try to build the project with mvn package
.

I created a function in VBA for you, so you can do this now in an easy way.
Create a VBA code module (macro) as you can see in this tutorial.
Module
in Insert
.Excel Macro-Enabled
in Save As
.Function listUnique(rng As Range) As Variant
Dim row As Range
Dim elements() As String
Dim elementSize As Integer
Dim newElement As Boolean
Dim i As Integer
Dim distance As Integer
Dim result As String
elementSize = 0
newElement = True
For Each row In rng.Rows
If row.Value <> "" Then
newElement = True
For i = 1 To elementSize Step 1
If elements(i - 1) = row.Value Then
newElement = False
End If
Next i
If newElement Then
elementSize = elementSize + 1
ReDim Preserve elements(elementSize - 1)
elements(elementSize - 1) = row.Value
End If
End If
Next
distance = Range(Application.Caller.Address).row - rng.row
If distance < elementSize Then
result = elements(distance)
listUnique = result
Else
listUnique = ""
End If
End Function
Just enter =listUnique(range)
to a cell. The only parameter is range
that is an ordinary Excel range. For example: A$1:A$28
or H$8:H$30
.
range
must be a column.range
starts.It works in columns that have empty cells in them. Also the function outputs nothing (not errors) if you overwind the cells (calling the function) into places where should be no output, as I did it in the previous example's "2. Grow it" part.
First of all - use single quotes around your date literals!
Second of all, I would strongly recommend always using the ISO-8601 date format - this works regardless of what your locale, regional or language settings are on your SQL Server.
The ISO-8601 format is either:
YYYYMMDD
for dates only (e.g. 20110825
for the 25th of August, 2011)YYYY-MM-DDTHH:MM:SS
for dates and time (e.g. 2011-08-25T14:15:00
for 25th of AUgust, 14:15/2:15pm in the afternoon)Note the official docs on connection configuration variables or "behavioral" variables - which aren't listed in host vars, appears to be List of Behavioral Inventory Parameters in the Inventory documentation.
P.S. The sudo
option is undocumented there (yes its sudo
not ansible_sudo
as you'd expect ...) and probably a couple more aren't, but thats best doc I've found on em.
You can use the command palette to solve this issue.
Step 1: Ctrl + Shift + P
(to activate the command palette)
Step 2: Type "Indentation", Choose "Indentation: Convert to Tabs"
Try:
public class Main {
public static void main(String[] args) {
String line = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";
String[] tokens = line.split(",(?=(?:[^\"]*\"[^\"]*\")*[^\"]*$)", -1);
for(String t : tokens) {
System.out.println("> "+t);
}
}
}
Output:
> foo
> bar
> c;qual="baz,blurb"
> d;junk="quux,syzygy"
In other words: split on the comma only if that comma has zero, or an even number of quotes ahead of it.
Or, a bit friendlier for the eyes:
public class Main {
public static void main(String[] args) {
String line = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";
String otherThanQuote = " [^\"] ";
String quotedString = String.format(" \" %s* \" ", otherThanQuote);
String regex = String.format("(?x) "+ // enable comments, ignore white spaces
", "+ // match a comma
"(?= "+ // start positive look ahead
" (?: "+ // start non-capturing group 1
" %s* "+ // match 'otherThanQuote' zero or more times
" %s "+ // match 'quotedString'
" )* "+ // end group 1 and repeat it zero or more times
" %s* "+ // match 'otherThanQuote'
" $ "+ // match the end of the string
") ", // stop positive look ahead
otherThanQuote, quotedString, otherThanQuote);
String[] tokens = line.split(regex, -1);
for(String t : tokens) {
System.out.println("> "+t);
}
}
}
which produces the same as the first example.
As mentioned by @MikeFHay in the comments:
I prefer using Guava's Splitter, as it has saner defaults (see discussion above about empty matches being trimmed by
String#split()
, so I did:Splitter.on(Pattern.compile(",(?=(?:[^\"]*\"[^\"]*\")*[^\"]*$)"))
Here is another one if anyone needs one for minutes and seconds:
var mins = 10; //Set the number of minutes you need
var secs = mins * 60;
var currentSeconds = 0;
var currentMinutes = 0;
/*
* The following line has been commented out due to a suggestion left in the comments. The line below it has not been tested.
* setTimeout('Decrement()',1000);
*/
setTimeout(Decrement,1000);
function Decrement() {
currentMinutes = Math.floor(secs / 60);
currentSeconds = secs % 60;
if(currentSeconds <= 9) currentSeconds = "0" + currentSeconds;
secs--;
document.getElementById("timerText").innerHTML = currentMinutes + ":" + currentSeconds; //Set the element id you need the time put into.
if(secs !== -1) setTimeout('Decrement()',1000);
}
Write your own is the best solution for now. Here is an example of a Converter that can do both way Normal and Inverted. If you have any problems with this just ask.
[ValueConversion(typeof(bool), typeof(Visibility))]
public class InvertableBooleanToVisibilityConverter : IValueConverter
{
enum Parameters

Normal, Inverted

var boolValue = (bool)value;
var direction = (Parameters)Enum.Parse(typeof(Parameters), (string)parameter);
if(direction == Parameters.Inverted)
return !boolValue? Visibility.Visible : Visibility.Collapsed;
return boolValue? Visibility.Visible : Visibility.Collapsed;
}

return null;

The android developers example of loading bitmaps efficiently uses a custom asynctask (copied from jellybean) so you can use the executeOnExecutor in apis lower than < 11

If that is the entire line, it very well might be because you are missing a ;
at the end of the line.
First off, custom events don't play well with React components natively. So you cant just say <div onMyCustomEvent={something}>
in the render function, and have to think around the problem.
Secondly, after taking a peek at the documentation for the library you're using, the event is actually fired on document.body
, so even if it did work, your event handler would never trigger.
Instead, inside componentDidMount
somewhere in your application, you can listen to nv-enter by adding
document.body.addEventListener('nv-enter', function (event) {
// logic
});
Then, inside the callback function, hit a function that changes the state of the component, or whatever you want to do.
findById
is a convenience method on the model that's provided by Mongoose to find a document by its _id. The documentation for it can be found here.
Example:
// Search by ObjectId
var id = "56e6dd2eb4494ed008d595bd";
UserModel.findById(id, function (err, user) { ... } );
Functionally, it's the same as calling:
UserModel.findOne({_id: id}, function (err, user) { ... });
Note that Mongoose will cast the provided id
value to the type of _id
as defined in the schema (defaulting to ObjectId).
Your error looks like you are duplicating an already existing Primary Key in your DB. You should modify your sql code to implement its own primary key by using something like the IDENTITY keyword.
CREATE TABLE [DB] (
[DBId] bigint NOT NULL IDENTITY,
...
CONSTRAINT [DB_PK] PRIMARY KEY ([DB] ASC),
);
you can have an interface hierarchy and then extend your classes from selected interfaces :
public interface IAnimal {
}
public interface IBird implements IAnimal {
}
public interface IHorse implements IAnimal {
}
public interface IPegasus implements IBird,IHorse{
}
and then define your classes as needed, by extending a specific interface :
public class Bird implements IBird {
}
public class Horse implements IHorse{
}
public class Pegasus implements IPegasus {
}
UPDATE
In Android Studio AVD:
Add following code in your click listener function,
NextFragment nextFrag= new NextFragment();
getActivity().getSupportFragmentManager().beginTransaction()
.replace(R.id.Layout_container, nextFrag, "findThisFragment")
.addToBackStack(null)
.commit();
The string "findThisFragment"
can be used to find the fragment later, if you need.
In your HTML you have set a "base" tag:
<base href="http://www.cyclistinsuranceaustralia.com.au/">
It might be a bit of an overkill, but I wrote an extension method, so you can do a LeftJoin
using the Join
syntax (at least in method call notation):
persons.LeftJoin(
phoneNumbers,
person => person.Id,
phoneNumber => phoneNumber.PersonId,
(person, phoneNumber) => new
{
Person = person,
PhoneNumber = phoneNumber?.Number
}
);
My code does nothing more than adding a GroupJoin
and a SelectMany
call to the current expression tree. Nevertheless, it looks pretty complicated because I have to build the expressions myself and modify the expression tree specified by the user in the resultSelector
parameter to keep the whole tree translatable by LINQ-to-Entities.

As the jQuery API says: "Load JSON-encoded data from the server using a GET HTTP request."
http://api.jquery.com/jQuery.getJSON/
So you cannot load a local file with that function. But as you browse the web then you will see that loading a file from filesystem is really difficult in javascript as the following thread says:
The simple way to fix this problem just types transform property for your element. and it will be fixed. Happy Coding :-)
.classname{
position: fixed;
transform: translate3d(0,0,0);
}
Also you can try his way as well this is also work fine.
.classname{
position: -webkit-sticky;

The easiest way to get Primary Key
and Foreign Key
for a table is:
/* Get primary key and foreign key for a table */
USE DatabaseName;
SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE CONSTRAINT_NAME LIKE 'PK%' AND
TABLE_NAME = 'TableName'
SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE CONSTRAINT_NAME LIKE 'FK%' AND
TABLE_NAME = 'TableName'
Here is a version of Robert B's answer that works for List<T>
and sorting by a specified String property of the object using Reflection and no 3rd party libraries
/**
* Sorts a List by the specified String property name of the object.
*
* @param list
* @param propertyName
*/
public static <T> void sortList(List<T> list, final String propertyName) {
if (list.size() > 0) {
Collections.sort(list, new Comparator<T>() {
@Override
public int compare(final T object1, final T object2) {
String property1 = (String)ReflectionUtils.getSpecifiedFieldValue (propertyName, object1);
String property2 = (String)ReflectionUtils.getSpecifiedFieldValue (propertyName, object2);
return property1.compareToIgnoreCase (property2);
}
});
}
}
public static Object getSpecifiedFieldValue (String property, Object obj) {
Object result = null;
try {
Class<?> objectClass = obj.getClass();
Field objectField = getDeclaredField(property, objectClass);
if (objectField!=null) {
objectField.setAccessible(true);
result = objectField.get(obj);
}
} catch (Exception e) {
}
return result;
}
public static Field getDeclaredField(String fieldName, Class<?> type) {
Field result = null;
try {
result = type.getDeclaredField(fieldName);
} catch (Exception e) {
}
if (result == null) {
Class<?> superclass = type.getSuperclass();
if (superclass != null && !superclass.getName().equals("java.lang.Object")) {
return getDeclaredField(fieldName, type.getSuperclass());
}
}
return result;
}
Use the synchronized
keyword.
class sample {
private String msg=null;
public synchronized void newmsg(String x){
msg=x;
}
public synchronized string getmsg(){
String temp=msg;
msg=null;
return msg;
}
}
Using the synchronized
keyword on the methods will require threads to obtain a lock on the instance of sample
. Thus, if any one thread is in newmsg()
, no other thread will be able to get a lock on the instance of sample
, even if it were trying to invoke getmsg()
.
On the other hand, using synchronized
methods can become a bottleneck if your methods perform long-running operations - all threads, even if they want to invoke other methods in that object that could be interleaved, will still have to wait.
IMO, in your simple example, it's ok to use synchronized methods since you actually have two methods that should not be interleaved. However, under different circumstances, it might make more sense to have a lock object to synchronize on, as shown in Joh Skeet's answer.

Extension attributes are added by Exchange. According to this Technet article something like this should work:
Set-Mailbox -Identity "anyUser" -ExtensionCustomAttribute4 @{Remove="myString"}
The accepted answer appears to be targetted for C++, so I thought I'd add an answer that pertains to C, and this differs in a few ways. There were also some changes made between ISO/IEC 9899:1989 (C90) and ISO/IEC 9899:1999 (C99).
main()
should be declared as either:
int main(void)
int main(int argc, char **argv)
Or equivalent. For example, int main(int argc, char *argv[])
is equivalent to the second one. In C90, the int
return type can be omitted as it is a default, but in C99 and newer, the int
return type may not be omitted.
If an implementation permits it, main()
can be declared in other ways (e.g., int main(int argc, char *argv[], char *envp[])
), but this makes the program implementation defined, and no longer strictly conforming.
The standard defines 3 values for returning that are strictly conforming (that is, does not rely on implementation defined behaviour): 0
and EXIT_SUCCESS
for a successful termination, and EXIT_FAILURE
for an unsuccessful termination. Any other values are non-standard and implementation defined. In C90, main()
must have an explicit return
statement at the end to avoid undefined behaviour. In C99 and newer, you may omit the return statement from main()
. If you do, and main()
finished, there is an implicit return 0
.
Finally, there is nothing wrong from a standards point of view with calling main()
recursively from a C program.
malloc for single chars or integers and calloc for dynamic arrays. ie pointer = ((int *)malloc(sizeof(int)) == NULL)
, you can do arithmetic within the brackets of malloc
but you shouldnt because you should use calloc
which has the definition of void calloc(count, size)
which means how many items you want to store ie count and size of data ie int
, char
etc.
This is supposed to print the ASCII value of the character, as %d
is the escape sequence for an integer. So the value given as argument of printf
is taken as integer when printed.
char ch = 'a';
printf("%d", ch);
Same holds for printf("%d", '\0');
, where the NULL character is interpreted as the 0 integer.
Finally, sizeof('\n')
is 4 because in C, this notation for characters stands for the corresponding ASCII integer. So '\n' is the same as 10 as an integer.
It all depends on the interpretation you give to the bytes.
You can trick MySQL into thinking you are actually specifying a primary key column. This allows you to "override" safe mode.
Assuming you have a table with an auto-incrementing numeric primary key, you could do the following:
DELETE FROM tbl WHERE id <> 0
Use CSS3
.container {
-webkit-column-count: 2;
-moz-column-count: 2;
column-count: 2;
-webkit-column-gap: 20px;
-moz-column-gap: 20px;
column-gap: 20px;
}

)In my case it happened when calling a function by passing a parameter of a Core Data managed object's property. At the time of calling the object was no longer existed, and that caused this error.
I have solved the issue by checking if the managed object exists or not before calling the function.
In python 3

>>> Path("/tmp/d/a.dat").name

After creating the new image, are you removing the old image from the DOM and replacing it with the new one?
You could be grabbing new images every updateImage call, but not adding them to the page.
There are a number of ways to do it. Something like this would work.
function updateImage()
{
var image = document.getElementById("theText");
if(image.complete) {
var new_image = new Image();
//set up the new image
new_image.id = "theText";
new_image.src = image.src;
// insert new image and remove old
image.parentNode.insertBefore(new_image,image);
image.parentNode.removeChild(image);
}
setTimeout(updateImage, 1000);
}
After getting that working, if there are still problems it is probably a caching issue like the other answers talk about.
One option would be to use a helper extension method like follows:
public static class MyExtensions
{
public static System.Type Type<T>(this T v)=>typeof(T);
}
var i=0;
console.WriteLine(i.Type().FullName);
See Soft Tabs and Tab Length under Settings > Editor Settings.
To toggle indentation modes quickly you can use Ctrl-Shift-P and search for Editor: Toggle Soft Tabs.
1.You can make overload functions.
SomeF(strin s){}
SomeF(string s, string s2){}
SomeF(string s1, string s2, string s3){}
More info: http://csharpindepth.com/Articles/General/Overloading.aspx
2.or you may create one function with params
SomeF( params string[] paramArray){}
SomeF("aa","bb", "cc", "dd", "ff"); // pass as many as you like
More info: https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/params
3.or you can use simple array
Main(string[] args){}
With the java.time classes built into Java 8 and later:
public static void main(String[] args) {
LocalDateTime localNow = LocalDateTime.now(TimeZone.getTimeZone("Europe/Madrid").toZoneId());
System.out.println(localNow);
// Prints current time of given zone without zone information : 2016-04-28T15:41:17.611
ZonedDateTime zoneNow = ZonedDateTime.now(TimeZone.getTimeZone("Europe/Madrid").toZoneId());
System.out.println(zoneNow);
// Prints current time of given zone with zone information : 2016-04-28T15:41:17.627+02:00[Europe/Madrid]
}
Unfortunately, this does not work on macOS. Despite the fact that I have export CONDA_DEFAULT_ENV='$HOME/anaconda3/envs/dev'
in my .zshrc and "python.pythonPath": "${env.CONDA_DEFAULT_ENV}/bin/python",
in my VSCode prefs, the built-in terminal does not use that environment's Python, even if I have started VSCode from the command line where that variable is set.
You can use Gnu-Parallel to run commands concurrently, works on Windows, Linux/Unix.

No, you can't undo, rollback or reverse a commit.
(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE
or similar, not an rm -rf /data/directory
scenario).
If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate
so that no checkpoint is run on shutdown.
You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.
If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.
Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base
, pg_clog
, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog
etc. No part is unimportant.
Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.
If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT
or UPDATE
. Thus, the old versions of the UPDATE
d rows might still be lying around, present but inaccessible.
Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter
and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl
in immediate
mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.
Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.
You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.
I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOAST
ed data so it's of limited utility. Give it a try, if you're lucky it might work.
See: pg_dirtyread on GitHub.
I've removed what I'd written in this section as it's obsoleted by that tool.
See also PostgreSQL row storage fundamentals
See my blog entry Preventing PostgreSQL database corruption.
On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED
for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.
As RedBlueThing and analog said:
dir()
gives a list of in scope variablesglobals()
gives a dictionary of global variableslocals()
gives a dictionary of local variablesUsing the interactive shell (version 2.6.9), after creating variables a = 1
and b = 2
, running dir()
gives
['__builtins__', '__doc__', '__name__', '__package__', 'a', 'b']
running locals()
gives
{'a': 1, 'b': 2, '__builtins__': <module '__builtin__' (built-in)>, '__package__': None, '__name__': '__main__', '__doc__': None}
Running globals()
gives exactly the same answer as locals()
in this case.
I haven't gotten into any modules, so all the variables are available as both local and global variables. locals()
and globals()
list the values of the variables as well as the names; dir()
only lists the names.
If I import a module and run locals()
or globals()
inside the module, dir()
still gives only a small number of variables; it adds __file__
to the variables listed above. locals()
and globals()
also list the same variables, but in the process of printing out the dictionary value for __builtin__
, it lists a far larger number of variables: built-in functions, exceptions, and types such as "'type': <type 'type'>
", rather than just the brief <module '__builtin__' (built-in)>
as shown above.
For more about dir()
see Python 2.7 quick reference at New Mexico Tech or the dir() function at ibiblio.org.
For more about locals()
and globals()
see locals and globals at Dive Into Python and a page about globals at New Mexico Tech.
[Comment: @Kurt: You gave a link to enumerate-or-list-all-variables-in-a-program-of-your-favorite-language-here but that answer has a mistake in it. The problem there is: type(name)
in that example will always return <type 'str'>
. You do get a list of the variables, which answers the question, but with incorrect types listed beside them. This was not obvious in your example because all the variables happened to be strings anyway; however, what it's returning is the type of the name of the variable instead of the type of the variable. To fix this: instead of print type(name)
use print eval('type(' + name + ')')
. I apologize for posting a comment in the answer section but I don't have comment posting privileges, and the other question is closed.]
In order to make that working I had to set:
compile ("com.android.support:support-v4:22.2.0")
compile ("com.android.support:appcompat-v7:22.2.0")
compile ("com.android.support:support-annotations:22.2.0")
compile ("com.android.support:recyclerview-v7:22.2.0")
compile ("com.android.support:design:22.2.0")
compile ("com.android.support:design:22.2.0")
Documentation states something different (docs):
com.android.support:support-design:22.0.0
You can split the processing into a specified number of threads using an approach like this:
import threading
def process(items, start, end):
for item in items[start:end]:
try:
api.my_operation(item)
except Exception:
print('error with item')
def split_processing(items, num_splits=4):
split_size = len(items) // num_splits
threads = []
for i in range(num_splits):
# determine the indices of the list this thread will handle
start = i * split_size
# special case on the last chunk to account for uneven splits
end = None if i+1 == num_splits else (i+1) * split_size
# create the thread
threads.append(
threading.Thread(target=process, args=(items, start, end)))
threads[-1].start() # start the thread we just created
# wait for all threads to finish
for t in threads:
t.join()
split_processing(items)
Async solution, it's better when the data is big:
// base64 to buffer
function base64ToBufferAsync(base64) {
var dataUrl = "data:application/octet-binary;base64," + base64;
fetch(dataUrl)
.then(res => res.arrayBuffer())
.then(buffer => {
console.log("base64 to buffer: " + new Uint8Array(buffer));
})
}
// buffer to base64
function bufferToBase64Async( buffer ) {
var blob = new Blob([buffer], {type:'application/octet-binary'});
console.log("buffer to blob:" + blob)
var fileReader = new FileReader();
fileReader.onload = function() {
var dataUrl = fileReader.result;
console.log("blob to dataUrl: " + dataUrl);
var base64 = dataUrl.substr(dataUrl.indexOf(',')+1)
console.log("dataUrl to base64: " + base64);
};
fileReader.readAsDataURL(blob);
}
Maybe can help to check that the path to the xsd file has not 'strange' characters like 'é', or similar: I was having the same issue but when I changed to a path without the 'é' the error dissapeared.
For what its worth, as of this writing (Nov. 29, 2018), the updated API that seems to work on my end is using this link:
https://wa.me/<phone number here>
Note:
Just replace the placeholder <phone number here>
with the intended phone number that you want to use INCLUDING the country code, this means I had to add +60
then the rest of the remaining number.
It doesn't work on my end without one (using Android and iOS at least). It doesn't work means an error message that says along the lines of "you don't have this number".
Reference:
The first version is a null object while the second is an Array object with zero elements.
Null may mean here for example that no location is available for that user, no location has been requested or that some restrictions apply. Hard to tell with no reference to the API.
You probably have a list containing one unicode string. The repr
of this is [u'String']
.
You can convert this to a list of byte strings using any variation of the following:
# Functional style.
print map(lambda x: x.encode('ascii'), my_list)
# List comprehension.
print [x.encode('ascii') for x in my_list]
# Interesting if my_list may be a tuple or a string.
print type(my_list)(x.encode('ascii') for x in my_list)
# What do I care about the brackets anyway?
print ', '.join(repr(x.encode('ascii')) for x in my_list)
# That's actually not a good way of doing it.
print ' '.join(repr(x).lstrip('u')[1:-1] for x in my_list)
Windows type
command works similarly to UNIX cat
.
Example 1: Merge with file names (This will merge file1.csv & file2.csv to create concat.csv)
type file1.csv file2.csv > concat.csv
Example 2: Merge files with pattern (This will merge all files with csv extension and create concat.csv)
When using asterisk(*) to concatenate all files. Please DON'T use same extension for target file(Eg. .csv). There should be some difference in pattern else target file will also be considered in concatenation
type *.csv > concat_csv.txt
There is an eclipse.ini (sts.ini) parameter that can help:
-Djava.net.useSystemProxies=true
A lot of effort wasted on this trivial setting each time I change the work environment... See one of the related bugs on eclipse bugzilla.
One non-trivial way is to run these two commands:
git stash
This will move your changes to the stash, bringing you back to the state of HEADgit stash drop
This will delete the latest stash created in the last command.When some elements lack ID, I use jQuery like this:
$(document).ready(function()
{
$('.myclass').attr('id', 'myid');
});
This might be a strange solution, but maybe someone find it useful.
g++ -o program file_name.cpp
.\program.exe
No it doesn't need to be constant, the reason why his code above is wrong is because he needs to include a variable name before the declaration.
int row = 8;
int col= 8;
int x[row][col];
In Xcode that will compile and run without any issues, in M$ C++ compiler in .NET it won't compile, it will complain that you cannot use a non const literal to initialize array, the size needs to be known at compile time
Fragment
can be thought of as non-root components in a composite tree of ui elements while activities sit at the top in the forest of composites(ui trees).
A rule of thumb on when not to use Fragment
is when as a child the fragment has a conflicting attribute, e.g., it may be immersive or may be using a different style all together or has some other architectural / logical difference and doesn't fit in the existing tree homogeneously.
A rule of thumb on when to prefer Activity
over Fragment
is when the task (or set of coherent task) is fully independent and reusable and does some heavy weight lifting and should not be burdened further to conform to another parent-child composite (SRP violation, second responsibility would be to conform to the composite). For e.g., a MediaCaptureActivity
that captures audio, video, photos etc and allows for edits, noise removal, annotations on photos etc and so on. This activity/module may have child fragments that do more granular work and conform to a common display theme.
Another solution could be something like following (works depending on your element's display property):
HTML:
<div class="left-align">Left</div>
<div class="right-align">Right</div>
CSS:
.left-align {
margin-left: 0;
margin-right: auto;
}
.right-align {
margin-left: auto;
margin-right: 0;
}
While I was having trouble join those two tables, I got away with doing exactly what I wanted by opening both remote databases at the same time. MySQL 5.6 (php 7.1) and the other MySQL 5.1 (php 5.6)
//Open a new connection to the MySQL server
$mysqli1 = new mysqli('server1','user1','password1','database1');
$mysqli2 = new mysqli('server2','user2','password2','database2');
//Output any connection error
if ($mysqli1->connect_error) {
die('Error : ('. $mysqli1->connect_errno .') '. $mysqli1->connect_error);
} else {
echo "DB1 open OK<br>";
}
if ($mysqli2->connect_error) {
die('Error : ('. $mysqli2->connect_errno .') '. $mysqli2->connect_error);
} else {
echo "DB2 open OK<br><br>";
}
If you get those two OKs on screen, then both databases are open and ready. Then you can proceed to do your querys.
$results = $mysqli1->query("SELECT * FROM video where video_id_old is NULL");
while($row = $results->fetch_array()) {
$theID = $row[0];
echo "Original ID : ".$theID." <br>";
$doInsert = $mysqli2->query("INSERT INTO video (...) VALUES (...)");
$doGetVideoID = $mysqli2->query("SELECT video_id, time_stamp from video where user_id = '".$row[13]."' and time_stamp = ".$row[28]." ");
while($row = $doGetVideoID->fetch_assoc()) {
echo "New video_id : ".$row["video_id"]." user_id : ".$row["user_id"]." time_stamp : ".$row["time_stamp"]."<br>";
$sql = "UPDATE video SET video_id_old = video_id, video_id = ".$row["video_id"]." where user_id = '".$row["user_id"]."' and video_id = ".$theID.";";
$sql .= "UPDATE video_audio SET video_id = ".$row["video_id"]." where video_id = ".$theID.";";
// Execute multi query if you want
if (mysqli_multi_query($mysqli1, $sql)) {
// Query successful do whatever...
}
}
}
// close connection
$mysqli1->close();
$mysqli2->close();
I was trying to do some joins but since I got those two DBs open, then I can go back and forth doing querys by just changing the connection $mysqli1
or $mysqli2
It worked for me, I hope it helps... Cheers
Try
if (!(i == 'InvKey' || i == 'PostDate')) {
or
if (i != 'InvKey' || i != 'PostDate') {
that says if i does not equals InvKey

Some servers have multiple MySQL versions installed and configured. Make sure you are dealing with the correct version running with a Unix command of:
ps -ax | grep mysql
You can use MATCH
for instance.
Select the column from the first cell, for example cell A2 to cell A100 and insert a conditional formatting, using 'New Rule...' and the option to conditional format based on a formula.
In the entry box, put:
=MATCH(A2, 'Sheet2'!A:A, 0)
Pick the desired formatting (change the font to red or fill the cell background, etc) and click OK.
MATCH
takes the value A2
from your data table, looks into 'Sheet2'!A:A
and if there's an exact match (that's why there's a 0
at the end), then it'll return the row number.
Note: Conditional formatting based on conditions from other sheets is available only on Excel 2010 onwards. If you're working on an earlier version, you might want to get the list of 'Don't check' in the same sheet.
EDIT: As per new information, you will have to use some reverse matching. Instead of the above formula, try:
=SUM(IFERROR(SEARCH('Sheet2'!$A$1:$A$44, A2),0))
I have same issue. Error message for me is not complete. But in my case, I've added generation jar with sources. By placing this code in pom.xml:
<build>
<pluginManagement>
<plugins>
<plugin>
<artifactId>maven-source-plugin</artifactId>
<version>2.1.2</version>
<executions>
<execution>
<phase>deploy</phase>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
</build>
So in deploy phase I execute source:jar goal which produces jar with sources. And deploy ends with BUILD SUCCESS
You could do this:
#if __WORDSIZE == 64
char *size = "64bits";
#else
char *size = "32bits";
#endif
A simpler version of your code would be:
dict(zip(names, d.values()))
If you want to keep the same structure, you can change it to:
vlst = list(d.values())
{names[i]: vlst[i] for i in range(len(names))}
(You can just as easily put list(d.values())
inside the comprehension instead of vlst
; it's just wasteful to do so since it would be re-generating the list every time).

In our case we had a query which loads multiple items with select * from x where something in (...) The in part was so long for benchmark test.(17mb as text query). Query is valid but text so long. Shortening the query solved the problem.
xhr.getResponseHeader('Set-Cookie');
It won't work for me.
I use this
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1);
if (c.indexOf(name) != -1) return c.substring(name.length,c.length);
}
return "";
}
success: function(output, status, xhr) {
alert(getCookie("MyCookie"));
},
Although its an old question let me give my input on it as well.
abstract class: Inside abstract class we can declare instance variables, which are required to the child class
Interface: Inside interface every variables is always public static and final we cannot declare instance variables
abstract class: Abstract class can talk about state of object
Interface: Interface can never talk about state of object
abstract class: Inside Abstract class we can declare constructors
Interface: Inside interface we cannot declare constructors as purpose of
constructors is to initialize instance variables. So what
is the need of constructor there if we cannot have instance
variables in interfaces.
abstract class: Inside abstract class we can declare instance and static blocks
Interface: Interfaces cannot have instance and static blocks.
abstract class: Abstract class cannot refer lambda expression
Interfaces: Interfaces with single abstract method can refer lambda expression
abstract class: Inside abstract class we can override OBJECT CLASS methods
Interfaces: We cannot override OBJECT CLASS methods inside interfaces.
I will end on the note that:
Default method concepts/static method concepts in interface came just to save implementation classes but not to provide meaningful useful implementation. Default methods/static methods are kind of dummy implementation, "if you want you can use them or you can override them (in case of default methods) in implementation class" Thus saving us from implementing new methods in implementation classes whenever new methods in interfaces are added. Therefore interfaces can never be equal to abstract classes.
If you have the XP resource kit, you can use robocopy to move all the old directories into a single directory, then use rmdir to delete just that one:
mkdir c:\temp\OldDirectoriesGoHere
robocopy c:\logs\SoManyDirectoriesToDelete\ c:\temp\OldDirectoriesGoHere\ /move /minage:7
rmdir /s /q c:\temp\OldDirectoriesGoHere
The other option in this particular case would be to type the degree symbol: °
R seems to handle it fine. Type Option-k on a Mac to get it. Not sure about other platforms.
Other than win32, if your company had set up you web outlook, you can also try PYTHON REST API, which is officially made by Microsoft. (https://msdn.microsoft.com/en-us/office/office365/api/mail-rest-operations)
Use Math.Round(double);
I have used it myself. It actually rounds off the decimal places.
d = 19.82;
ans = Math.round(d);
System.out.println(ans);
// Output : 20
d = 19.33;
ans = Math.round(d);
System.out.println(ans);
// Output : 19
Hope it Helps :-)
Yes, since it's a dynamically type language ;)
Read this for reference: PEP 257
Since Java9, both interfaces are deprecated, meaning you should not use them anymore. See Observer is deprecated in Java 9. What should we use instead of it?
However, you might still get interview questions about them...
First of all, create a virtual environment.
In Python 3.6
virtualenv --python=/usr/bin/python3.6 <path/to/new/virtualenv/>
In Python 2.7
virtualenv --python=/usr/bin/python2.7 <path/to/new/virtualenv/>
Then activate the environment and install all the packages available in the requirement.txt file.
source <path/to/new/virtualenv>/bin/activate
pip install -r <path/to/requirement.txt>
The easier is add [0]
- select first value of list with one element:
dfb = df[df['A']==5].index.values.astype(int)[0]
dfbb = df[df['A']==8].index.values.astype(int)[0]
dfb = int(df[df['A']==5].index[0])
dfbb = int(df[df['A']==8].index[0])
But if possible some values not match, error is raised, because first value not exist.
Solution is use next
with iter
for get default parameetr if values not matched:
dfb = next(iter(df[df['A']==5].index), 'no match')
print (dfb)
4
dfb = next(iter(df[df['A']==50].index), 'no match')
print (dfb)
no match
Then it seems need substract 1
:
print (df.loc[dfb:dfbb-1,'B'])
4 0.894525
5 0.978174
6 0.859449
Name: B, dtype: float64
Another solution with boolean indexing
or query
:
print (df[(df['A'] >= 5) & (df['A'] < 8)])
A B
4 5 0.894525
5 6 0.978174
6 7 0.859449
print (df.loc[(df['A'] >= 5) & (df['A'] < 8), 'B'])
4 0.894525
5 0.978174
6 0.859449
Name: B, dtype: float64
print (df.query('A >= 5 and A < 8'))
A B
4 5 0.894525
5 6 0.978174
6 7 0.859449
None of the above worked for me for some reason :/, so I added an element ref to a top element in app.component.html
, and (activate)=onNavigate($event)
to the router-outlet
.
<!--app.component.html-->
<div #topScrollAnchor></div>
<app-navbar></app-navbar>
<router-outlet (activate)="onNavigate($event)"></router-outlet>
Then I added the child to the app.component.ts file to the type of ElementRef
, and had it scroll to it on activation of the router-outlet.
export class AppComponent {
@ViewChild('topScrollAnchor') topScroll: ElementRef;
onNavigate(event): any {
this.topScroll.nativeElement.scrollIntoView({ behavior: 'smooth' });
}
}
Here's the code in stackblitz
Boom Check this for java Lovers :D We can modify it according to our need:
List<Pair<String, View.OnClickListener>> pairsList = new ArrayList<>();
pairsList.add(new Pair<>("38,50", v -> {
Intent intent = new Intent(SignUpActivity.this, WebActivity.class);
intent.putExtra("which", "tos");
startActivity(intent);
}));
pairsList.add(new Pair<>("81,95", v -> {
Intent intent = new Intent(SignUpActivity.this, WebActivity.class);
intent.putExtra("which", "policy");
startActivity(intent);
}));
makeLinks(pairsList); // Method calling
private void makeLinks(List<Pair<String, View.OnClickListener>> pairsList) {
SpannableString ss = new SpannableString(By signing up, I’m agree to PAKRISM’s Terms of Use and confirms that I have read Privacy Policy);
for (Pair<String, View.OnClickListener> pair : pairsList) {
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(View textView) {
//Toast.makeText(MyApplication.getAppContext(), "Clicked!", Toast.LENGTH_SHORT).show();
pair.second.onClick(textView);
}
@Override

You don't need jQuery for this. Here's a simple working example:
<!DOCTYPE html>
<html>
<head>
<title>box-shadow-experiment</title>
<style type="text/css">
#box-shadow-div{
position: fixed;
width: 1px;
height: 1px;
border-radius: 100%;
background-color:black;
box-shadow: 0 0 10px 10px black;
top: 49%;
left: 48.85%;
}
</style>
<script type="text/javascript">
window.onload = function(){
var bsDiv = document.getElementById("box-shadow-div");
var x, y;
// On mousemove use event.clientX and event.clientY to set the location of the div to the location of the cursor:
window.addEventListener('mousemove', function(event){
x = event.clientX;
y = event.clientY;
if ( typeof x !== 'undefined' ){
bsDiv.style.left = x + "px";
bsDiv.style.top = y + "px";
}
}, false);
}
</script>
</head>
<body>
<div id="box-shadow-div"></div>
</body>
</html>
I chose position: fixed;
so scrolling wouldn't be an issue.
DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
String cunvertCurrentDate="06/09/2015";
Date date = new Date();
date = df.parse(cunvertCurrentDate);
You make one div somewhere on the page and put this code:
<div id="winSize"></div>
<script>
var WindowsSize=function(){
var h=$(window).height(),
w=$(window).width();
$("#winSize").html("<p>Width: "+w+"<br>Height: "+h+"</p>");
};
$(document).ready(WindowsSize);
$(window).resize(WindowsSize);
</script>
Here is a snippet:
var WindowsSize=function(){_x000D_
var h=$(window).height(),_x000D_
w=$(window).width();_x000D_
$("#winSize").html("<p>Width: "+w+"<br>Height:"+h+"</p>");_x000D_
};_x000D_
$(document).ready(WindowsSize); _x000D_
$(window).resize(WindowsSize);
_x000D_
#winSize{_x000D_
position:fixed;_x000D_
bottom:1%;_x000D_

}
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_

Of course, adapt it to fit your needs! ;)

After hours of research this solution worked for me:
(disclaimer: results may vary due to circumstances)
the Library not found -lPods-(someCocoapod)
error was due to multiple entries in the :
Settings(Target) > Build Settings > Linking > 'Other Linker Flags'
A lot of other posts had me look there and I would see changes to the error when I messed around with the entries, but I kept getting some variation on the same error.
Too many hours lost ...
remove the -lPods-(someCocoaPod) lines in the 'Other Linker Flags' list BUT only if $(inherited) is at the top. At first I was unsure, but the reassuring sign was that I still saw references to my cocoapods when I left the edit mode(inherited). I tested in debug and release, both of which were giving me errors, and the problem was immediately resolved.
Flags are used when an enumerable value represents a collection of enum members.
here we use bitwise operators, | and &
Example
[Flags]
public enum Sides { Left=0, Right=1, Top=2, Bottom=3 }
Sides leftRight = Sides.Left | Sides.Right;
Console.WriteLine (leftRight);//Left, Right
string stringValue = leftRight.ToString();
Console.WriteLine (stringValue);//Left, Right
Sides s = Sides.Left;
s |= Sides.Right;
Console.WriteLine (s);//Left, Right
s ^= Sides.Right; // Toggles Sides.Right
Console.WriteLine (s); //Left
For checking positive integer:
var isPositiveInteger = function(n) {
return ($.isNumeric(n)) && (Math.floor(n) == n) && (n > 0);
}
I use XAMPP. In C:\xampp\php\php.ini, the entry for openssl did not exist, so I added "extension=php_openssl.dll" on line 989, and composer worked.
A Popen
object has a .wait()
method exactly defined for this: to wait for the completion of a given subprocess (and, besides, for retuning its exit status).
If you use this method, you'll prevent that the process zombies are lying around for too long.
(Alternatively, you can use subprocess.call()
or subprocess.check_call()
for calling and waiting. If you don't need IO with the process, that might be enough. But probably this is not an option, because your if the two subprocesses seem to be supposed to run in parallel, which they won't with (check_
)call()
.)
If you have several subprocesses to wait for, you can do
exit_codes = [p.wait() for p in p1, p2]
which returns as soon as all subprocesses have finished. You then have a list of return codes which you maybe can evaluate.
You just need 775
for /var/www/html
as long as you are logging in as myuser. The 7
octal in the middle (which is for "group" acl) ensures that the group has permission to read/write/execute. As long as you belong to the group that owns the files, "myuser" should be able to write to them. You may need to give group permissions to all the files in the docuemnt root, though:
chmod -R g+w /var/www/html
The easiest way if you have
<div ng-repeat="person in data | filter: query"></div>
Filtered data length
<div>{{ (data | filter: query).length }}</div>
There's also the submit event, which can be triggered like this $("#form_id").submit(). You'd use this method if the form is well represented in HTML already. You'd just read in the page, populate the form inputs with stuff, then call .submit(). It'll use the method and action defined in the form's declaration, so you don't need to copy it into your javascript.
I came here to remind myself how to code a second index into the increment clause of a FOR loop, which I knew could be done mainly from observing it in a sample that I incorporated into another project, that written in C++.
Today, I am working in C#, but I felt sure that it would obey the same rules in this regard, since the FOR statement is one of the oldest control structures in all of programming. Thankfully, I had recently spent several days precisely documenting the behavior of a FOR loop in one of my older C programs, and I quickly realized that those studies held lessons that applied to today's C# problem, in particular to the behavior of the second index variable.
For the unwary, following is a summary of my observations. Everything I saw happening today, by carefully observing variables in the Locals window, confirmed my expectation that a C# FOR statement behaves exactly like a C or C++ FOR statement.
If either of your index variables remains in scope when the loop ends, their value will be one higher than the threshold that stops the loop, in the case of the true index variable. Likewise, if, for example, the second variable is initialized to zero before the loop is entered, its value at the end will be the iteration count, assuming that it is an increment (++), not a decrement, and that nothing in the body of the loop changes its value.
We have been using jqGrid on a project and have had some good luck with it. Lots of options for inline editing, etc. If that stuff isn't necessary, then we've just used a plain foreach loop like @Hrvoje.
CodeIgniter Active Records do not currently support sub-queries, However I use the following approach:
#Create where clause
$this->db->select('id_cer');
$this->db->from('revokace');
$where_clause = $this->db->_compile_select();
$this->db->_reset_select();
#Create main query
$this->db->select('*');
$this->db->from('certs');
$this->db->where("`id` NOT IN ($where_clause)", NULL, FALSE);
_compile_select() and _reset_select() are two undocumented (AFAIK) methods which compile the query and return the sql (without running it) and reset the query.
On the main query the FALSE in the where clause tells codeigniter not to escape the query (or add backticks etc) which would mess up the query. (The NULL is simply because the where clause has an optional second parameter we are not using)
However you should be aware as _compile_select() and _reset_select() are not documented methods it is possible that there functionality (or existence) could change in future releases.
Try this It is working for me..
The syntax is GetFiles(string path, string searchPattern);
var filePath = Server.MapPath("~/App_Data/");
string[] filePaths = Directory.GetFiles(@filePath, "*.*");
This code will return all the files inside App_Data
folder.
The second parameter . indicates the searchPattern with File Extension where the first * is for file name and second is for format of the file or File Extension like (*.png - any file name with .png format.
It's also useful when you actually don't want to assign the value to anything, such as loading some class only once during runtime.
E.g.
static {
try {
Class.forName("com.example.jdbc.Driver");
} catch (ClassNotFoundException e) {
throw new ExceptionInInitializerError("Cannot load JDBC driver.", e);
}
}
Hey, there's another benefit, you can use it to handle exceptions. Imagine that getStuff()
here throws an Exception
which really belongs in a catch block:
private static Object stuff = getStuff(); // Won't compile: unhandled exception.
then a static
initializer is useful here. You can handle the exception there.
Another example is to do stuff afterwards which can't be done during assigning:
private static Properties config = new Properties();
static {
try {
config.load(Thread.currentThread().getClassLoader().getResourceAsStream("config.properties");
} catch (IOException e) {
throw new ExceptionInInitializerError("Cannot load properties file.", e);
}
}
To come back to the JDBC driver example, any decent JDBC driver itself also makes use of the static
initializer to register itself in the DriverManager
. Also see this and this answer.
The easiest way to match both
^\([0-9]{3}\)[0-9]{3}-[0-9]{4}$
and
^[0-9]{3}-[0-9]{3}-[0-9]{4}$
is to use alternation ((...|...)
): specify them as two mostly-separate options:
^(\([0-9]{3}\)|[0-9]{3}-)[0-9]{3}-[0-9]{4}$
By the way, when Americans put the area code in parentheses, we actually put a space after that; for example, I'd write (123) 123-1234
, not (123)123-1234
. So you might want to write:
^(\([0-9]{3}\) |[0-9]{3}-)[0-9]{3}-[0-9]{4}$
(Though it's probably best to explicitly demonstrate the format that you expect phone numbers to be in.)
Dim numberOfButtons As Integer
Dim buttons() as Button
Private Sub MyForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Redim buttons(numberOfbuttons)
for counter as integer = 0 to numberOfbuttons
With buttons(counter)
.Size = (10, 10)
.Visible = False
.Location = (55, 33 + counter*13)
.Text = "Button "+(counter+1).ToString ' or some name from an array you pass from main
'any other property
End With
'
next
End Sub
If you want to check which of the textboxes have information, or which radio button was clicked, you can iterate through a loop in an OK button.
If you want to be able to click individual array items and have them respond to events, add in the Form_load loop the following:
AddHandler buttons(counter).Clicked AddressOf All_Buttons_Clicked
then create
Private Sub All_Buttons_Clicked(ByVal sender As System.Object, ByVal e As System.EventArgs)
'some code here, can check to see which checkbox was changed, which button was clicked, by number or text
End Sub
when you call: objectYouCall.numberOfButtons = initial_value_from_main_program
response_yes_or_no_or_other = objectYouCall.ShowDialog()
For radio buttons, textboxes, same story, different ending.
Not answering to your direct questions, since there are already a lot of detailed answers, but it's worth mentioning, that to the contrary of Android documentation, Android Studio is suggesting to use the same version for compileSDKVersion
and targetSDKVersion
.
From Laravel 5.6 you can use whereDate:
$users = Users::where('status_id', 'active')
->whereDate( 'created_at', '>', now()->subDays(30))
->get();
You also have whereMonth / whereDay / whereYear / whereTime

:before
and :after
render inside a containerand <input> can not contain other elements.
Pseudo-elements can only be defined (or better said are only supported) on container elements. Because the way they are rendered is within the container itself as a child element. input
can not contain other elements hence they're not supported. A button
on the other hand that's also a form element supports them, because it's a container of other sub-elements.
If you ask me, if some browser does display these two pseudo-elements on non-container elements, it's a bug and a non-standard conformance. Specification directly talks about element content...
If we carefully read the specification it actually says that they are inserted inside a containing element:
Authors specify the style and location of generated content with the :before and :after pseudo-elements. As their names indicate, the :before and :after pseudo-elements specify the location of content before and after an element's document tree content. The 'content' property, in conjunction with these pseudo-elements, specifies what is inserted.
See? an element's document tree content. As I understand it this means within a container.
Also make sure php is enabled by uncommenting the
LoadModule php5_module libexec/apache2/libphp5.so
line that comes right after
LoadModule rewrite_module libexec/apache2/mod_rewrite.so
Make sure both those lines in
/etc/apache2/httpd.conf
are uncommented.
You have to replace the values one by one such as in a for-loop or copying another array over another such as using memcpy(..)
or std::copy
e.g.
for (int i = 0; i < arrayLength; i++) {
array[i] = newValue[i];
}
Take care to ensure proper bounds-checking and any other checking that needs to occur to prevent an out of bounds problem.
Check out James Padolsey's animateToSelector
Intro: This jQuery plugin will allow you to animate any element to styles specified in your stylesheet. All you have to do is pass a selector and the plugin will look for that selector in your StyleSheet and will then apply it as an animation.
I ran across this problem, in a solution with a WebAPI/MVC5 web project and a Feature Test project, that both drew off of the same data access (or, 'Core') project. I, like so many others here, am using a copy downloaded via NuGet in Visual Studio 2013.
What I did, was in Visual Studio added a x86 and x64 solution folder to the Feature Test and Web Projects. I then did a Right Click | Add Existing Item...
, and added the appropriate SQLite.interop.dll library from ..\SolutionFolder\packages\System.Data.SQLite.Core.1.0.94.0\build\net451\[appropriate architecture]
for each of those folders. I then did a Right Click | Properties
, and set Copy to Output Directory
to Always Copy
. The next time I needed to run my feature tests, the tests ran successfully.
Adding this late answer to show a case most people will come across. If you only need to see what is the last item in the list, use the last
key word:
<div *ngFor="let item of devcaseFeedback.reviewItems; let last = last">
<divider *ngIf="!last"></divider>
</div>
This will add the divider component to every item except the last.
Because of the comment below, I will add the rest of the ngFor
exported values that can be aliased to local variables (As are shown in the docs):
Select a range of cells (the entire column in this case), type in your formula, and hold down Ctrl while you press Enter. This places the formula in all selected cells.
If you don't mind muddying your references a bit, you can include Microsoft.Visualbasic,
and use this very short way.
Display the MessageBox
(new System.Threading.Thread(CloseIt)).Start();
MessageBox.Show("HI");
CloseIt Function:
public void CloseIt()
{
System.Threading.Thread.Sleep(2000);
Microsoft.VisualBasic.Interaction.AppActivate(
System.Diagnostics.Process.GetCurrentProcess().Id);
System.Windows.Forms.SendKeys.SendWait(" ");
}
Now go wash your hands!
Just in case, anyone's visiting this question in 2017 or later and looking for an easy-to-remember way, here's an elaborate blog post on Accessing Nested Objects in JavaScript without being bamboozled by
Cannot read property 'foo' of undefined error
Let's take this example structure
const user = {
id: 101,
email: '[email protected]',
personalInfo: {
name: 'Jack',
address: [{
line1: 'westwish st',
line2: 'washmasher',
city: 'wallas',
state: 'WX'
}]
}
}
To be able to access nested arrays, you can write your own array reduce util.
const getNestedObject = (nestedObj, pathArr) => {
return pathArr.reduce((obj, key) =>
(obj && obj[key] !== 'undefined') ? obj[key] : undefined, nestedObj);
}
// pass in your object structure as array elements
const name = getNestedObject(user, ['personalInfo', 'name']);
// to access nested array, just pass in array index as an element the path array.
const city = getNestedObject(user, ['personalInfo', 'address', 0, 'city']);
// this will return the city from the first address item.
There is also an excellent type handling minimal library typy that does all this for you.
With typy, your code will look like this
const city = t(user, 'personalInfo.address[0].city').safeObject;

Almost correctly.. Look at the joins, you are referring the wrong fields
SELECT student.firstname,
student.lastname,
exam.name,
exam.date,
grade.grade
FROM grade
INNER JOIN student ON student.studentId = grade.fk_studentId
INNER JOIN exam ON exam.examId = grade.fk_examId
ORDER BY exam.date
Here is a way to transform a date string with a time of day to a date object. For example to convert "20/10/2020 18:11:25" ("DD/MM/YYYY HH:MI:SS" format) to a date object
function newUYDate(pDate) {
let dd = pDate.split("/")[0].padStart(2, "0");
let mm = pDate.split("/")[1].padStart(2, "0");
let yyyy = pDate.split("/")[2].split(" ")[0];
let hh = pDate.split("/")[2].split(" ")[1].split(":")[0].padStart(2, "0");
let mi = pDate.split("/")[2].split(" ")[1].split(":")[1].padStart(2, "0");
let secs = pDate.split("/")[2].split(" ")[1].split(":")[2].padStart(2, "0");
mm = (parseInt(mm) - 1).toString(); // January is 0
return new Date(yyyy, mm, dd, hh, mi, secs);
}
Because of the GDPR it makes no sense to use the iframe, you should rather use the object tag with the embed tag and also use the embed link.
<object width="100%" height="333">
<param name="movie" value="https://www.youtube-nocookie.com/embed/Sdg0ef2PpBw">
<embed src="https://www.youtube-nocookie.com/embed/Sdg0ef2PpBw" width="100%" height="333">
</object>

You should also activate the extended data protection mode function to receive the no cookie url.
type="application/x-shockwave-flash"
flash does not have to be used
Nocookie, however, means that data is still being transmitted, namely the thumbnail that is loaded from YouTube. But at least data is no longer passed on to advertising networks (as example DoubleClick). And no user data is stored on your website by youtube.
Update: In modern browsers you can use the form
attribute to do this.
As far as I know, you cannot do this without javascript.
Here's what the spec says
The elements used to create controls generally appear inside a FORM element, but may also appear outside of a FORM element declaration when they are used to build user interfaces. This is discussed in the section on intrinsic events. Note that controls outside a form cannot be successful controls.
That's my bold
A submit
button is considered a control.

From the comments
I have a multi tabbed settings area with a button to update all, due to the design of it the button would be outside of the form.
Why not place the input
inside the form, but use CSS to position it elsewhere on the page?
An alternative is to look for a unix shell which does give you logical operators and a whole lot more. You can get a native win32 implementation of a Bourne shell here if you don't want to go the cygwin route. A native bash can be found here. I'm quite certain you could easily google other good alternatives such as zsh or tcsh.

Could it be that your file is not ISO-8859-15 encoded? You should be able to check with the file command:
file YourFile.txt
Also, you can use iconv without providing the encoding of the original file:
iconv -t UTF-8 YourFile.txt
Please note that there's a naming convention. Your lib needs to be called libexample.so .
LoadLibrary("example") will look for libexample.so.
The .so library needs to be inside the apk under the lib folder (since you are developing for Android, it needs to be under the lib/armeabi and lib/armeabi-v7a folders - why both folders ? some versions of Android look under lib/armeabi and some look under lib/armeabi-v7a ... se what works for you ).
Other things to look for :
make sure you compile for the correct architecture (if you compile for armeabi v5 it won't work on armeabiv7 or armeabiv7s ).
make sure your exported prototypes are used in the correct class (check the hello jni example. Your exposed functions need to look something like Java_mypackagename_myjavabridgeclass_myfunction).
For example the function Java_com_example_sample_hello will translate in the java class com.example.sample , function hello.
Range.Rows
and Range.Columns
return essentially the same Range except for the fact that the new Range has a flag which indicates that it represents Rows or Columns. This is necessary for some Excel properties such as Range.Count and Range.Hidden and for some methods such as Range.AutoFit()
:
Range.Rows.Count
returns the number of rows in Range.Range.Columns.Count
returns the number of columns in Range.Range.Rows.AutoFit()
autofits the rows in Range.Range.Columns.AutoFit()
autofits the columns in Range.You might find that Range.EntireRow
and Range.EntireColumn
are useful, although they still are not exactly what you are looking for. They return all possible columns for EntireRow
and all possible rows for EntireColumn
for the represented range.
I know this because SpreadsheetGear for .NET comes with .NET APIs which are very similar to Excel's APIs. The SpreadsheetGear API comes with several strongly typed overloads to the IRange indexer including the one you probably wish Excel had:
IRange this[int row1, int column1, int row2, int column2];
