This exception message doesn't mean it requires a primary key to be defined in your database, it means it requires a primary key to be defined in your class.
Although you've attempted to do so:
private Guid _id; [Key] public Guid ID { get { return _id; } }
This has no effect, as Entity Framework ignores read-only properties. It has to: when it retrieves a Fruits
record from the database, it constructs a Fruit
object, and then calls the property setters for each mapped property. That's never going to work for read-only properties.
You need Entity Framework to be able to set the value of ID
. This means the property needs to have a setter.
I'm using PreviewKeyDown
private void _calendar_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e){
switch (e.KeyCode){
case Keys.Down:
case Keys.Right:
//action
break;
case Keys.Up:
case Keys.Left:
//action
break;
}
}
Once you've got expandtab on as per the other answers, the extremely convenient way to convert existing files according to your new settings is:
:retab
It will work on the current buffer.
You are just creating your array incorrectly. You could use http_build_query:
$fields = array(
'username' => "annonymous",
'api_key' => urlencode("1234"),
'images' => array(
urlencode(base64_encode('image1')),
urlencode(base64_encode('image2'))
)
);
$fields_string = http_build_query($fields);
So, the entire code that you could use would be:
<?php
//extract data from the post
extract($_POST);
//set POST variables
$url = 'http://api.example.com/api';
$fields = array(
'username' => "annonymous",
'api_key' => urlencode("1234"),
'images' => array(
urlencode(base64_encode('image1')),
urlencode(base64_encode('image2'))
)
);
//url-ify the data for the POST
$fields_string = http_build_query($fields);
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
//execute post
$result = curl_exec($ch);
echo $result;
//close connection
curl_close($ch);
?>
Answer to the question is : There are different way to print stderr in python but that depends on 1.) which python version we are using 2.) what exact output we want.
The differnce between print and stderr's write function: stderr : stderr (standard error) is pipe that is built into every UNIX/Linux system, when your program crashes and prints out debugging information (like a traceback in Python), it goes to the stderr pipe.
print: print is a wrapper that formats the inputs (the input is the space between argument and the newline at the end) and it then calls the write function of a given object, the given object by default is sys.stdout, but we can pass a file i.e we can print the input in a file also.
Python2: If we are using python2 then
>>> import sys
>>> print "hi"
hi
>>> print("hi")
hi
>>> print >> sys.stderr.write("hi")
hi
Python2 trailing comma has in Python3 become a parameter, so if we use trailing commas to avoid the newline after a print, this will in Python3 look like print('Text to print', end=' ') which is a syntax error under Python2.
http://python3porting.com/noconv.html
If we check same above sceario in python3:
>>> import sys
>>> print("hi")
hi
Under Python 2.6 there is a future import to make print into a function. So to avoid any syntax errors and other differences we should start any file where we use print() with from future import print_function. The future import only works under Python 2.6 and later, so for Python 2.5 and earlier you have two options. You can either convert the more complex print to something simpler, or you can use a separate print function that works under both Python2 and Python3.
>>> from __future__ import print_function
>>>
>>> def printex(*args, **kwargs):
... print(*args, file=sys.stderr, **kwargs)
...
>>> printex("hii")
hii
>>>
Case: Point to be noted that sys.stderr.write() or sys.stdout.write() ( stdout (standard output) is a pipe that is built into every UNIX/Linux system) is not a replacement for print, but yes we can use it as a alternative in some case. Print is a wrapper which wraps the input with space and newline at the end and uses the write function to write. This is the reason sys.stderr.write() is faster.
Note: we can also trace and debugg using Logging
#test.py
import logging
logging.info('This is the existing protocol.')
FORMAT = "%(asctime)-15s %(clientip)s %(user)-8s %(message)s"
logging.basicConfig(format=FORMAT)
d = {'clientip': '192.168.0.1', 'user': 'fbloggs'}
logging.warning("Protocol problem: %s", "connection reset", extra=d)
https://docs.python.org/2/library/logging.html#logger-objects
Rethink your approach. Why would you copy only part of the sheet? You are referring to a named range "WholePrintArea" which doesn't exist. Also you should never use activate, select, copy or paste in your script. These make the "script" vulnerable to user actions and other simultaneous executions. In worst case scenario data ends up in wrong hands.
With the carrier module:
var carrier = require('carrier');
process.stdin.resume();
carrier.carry(process.stdin, function(line) {
console.log('got one line: ' + line);
});
if you need to eliminate duplicates on specific keys, such as a mysqli id, here's a simple funciton
function search_array_compact($data,$key){
$compact = [];
foreach($data as $row){
if(!in_array($row[$key],$compact)){
$compact[] = $row;
}
}
return $compact;
}
Bonus Points You can pass an array of keys and add an outer foreach, but it will be 2x slower per additional key.
Delete the repository folder from "C:\Users\usename.m2" and create again or update maven project.
You can get the ListView first, and then get the Selected ListViewItem. I have an example for ListBox, but ListView should be similar.
private void listBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
ListBox box = sender as ListBox;
if (box == null) {
return;
}
MyInfo info = box.SelectedItem as MyInfo;
if (info == null)
return;
/* your code here */
}
e.Handled = true;
}
update json_source_tabcol as d
set isnullable = a.is_Nullable
from information_schema.columns as a
where a.table_name =d.table_name
and a.table_schema = d.table_schema
and a.column_name = d.column_name;
Use a sub query similar to the below.
UPDATE P
SET extrasPrice = sub.TotalPrice from
BookingPitches p
inner join
(Select PitchID, Sum(Price) TotalPrice
from dbo.BookingPitchExtras
Where [Required] = 1
Group by Pitchid
) as Sub
on p.Id = e.PitchId
where p.BookingId = 1
Things have moved on a bit since this thread started.
Now, you could use
string.Concat(s.TakeWhile((c) => c != '-'));
If your user has a local folder e.g. Linux, in your users home folder you could create a .my.cnf file and provide the credentials to access the server there. for example:-
[client]
host=localhost
user=yourusername
password=yourpassword or exclude to force entry
database=mygotodb
Mysql would then open this file for each user account read the credentials and open the selected database.
Not sure on Windows, I upgraded from Windows because I needed the whole house not just the windows (aka Linux) a while back.
Static methods use the class as the object for locking, which is Utils.class for your example. So yes, it is OK.
so if you need want use this code )
import { useRoutes } from "./routes";
import { BrowserRouter as Router } from "react-router-dom";
export const App = () => {
const routes = useRoutes(true);
return (
<Router>
<div className="container">{routes}</div>
</Router>
);
};
// ./routes.js
import { Switch, Route, Redirect } from "react-router-dom";
export const useRoutes = (isAuthenticated) => {
if (isAuthenticated) {
return (
<Switch>
<Route path="/links" exact>
<LinksPage />
</Route>
<Route path="/create" exact>
<CreatePage />
</Route>
<Route path="/detail/:id">

</Switch>
);
}
return (

</Switch>
);
};
Try this to remove the labels (but not the ticks):

plt.setp( ax.get_xticklabels(), visible=False)
I've had the same issue. In my project, I had the following dependencies :
For legacy reasons, the appcompat was fetched from the Google Maven repo, whereas the android-support was a local .jar.
When I figured out this, and replaced this local reference with a maven reference, it just solved my build issue.
Here's the diff of my app/build.gradle :
The chosen answer looks like does not apply to modern browsers, at least on Firefox 52. What I observed is that the requests of loading resources like css, javascript are issued before HTML parser reaches the element, for example
<html>
<head>
<!-- prints the date before parsing and blocks HTMP parsering -->
<script>
console.log("start: " + (new Date()).toISOString());
for(var i=0; i<1000000000; i++) {};
</script>
<script src="jquery.js" type="text/javascript"></script>
<script src="abc.js" type="text/javascript"></script>
<link rel="stylesheets" type="text/css" href="abc.css"></link>
<style>h2{font-wight:bold;}</style>
<script>
$(document).ready(function(){
$("#img").attr("src", "kkk.png");
});
</script>
</head>
<body>
<img id="img" src="abc.jpg" style="width:400px;height:300px;"/>
<script src="kkk.js" type="text/javascript"></script>
</body>
</html>
What I found that the start time of requests to load css and javascript resources were not being blocked. Looks like Firefox has a HTML scan, and identify key resources(img resource is not included) before starting to parse the HTML.
Using zip4j you can simply do this
ZipFile zipfile = new ZipFile(new File("D:\\reports\\january\\filename.zip"));
zipfile.addFolder(new File("D:\\reports\\january\\"));
It will archive your folder and everything in it.
Use the .extractAll
method to get it all out:
zipfile.extractAll("D:\\destination_directory");
I have used ndk.dir=/usr/shareData/android-ndk-r11b

If what you are needing is an array of arrays, you can do this way:
key:
- [ 'value11', 'value12', 'value13' ]
- [ 'value21', 'value22', 'value23' ]
In PyCharm, I'd leave it out. It turns off the UTF-8 indicator at the bottom with a warning that the encoding is hard-coded. Don't think you need the PyCharm comment mentioned above.
Try setting your font from the menu and then typing

This should display to you the string that Vim has set this option to. You'll need to escape any spaces.
In order to embed your channel, all you need to do is copy then paste the following code in another web-page.
<script src="http://www.gmodules.com/ig/ifr?url=http://www.google.com/ig/modules/youtube.xml&up_channel=YourChannelName&synd=open&w=320&h=390&title=&border=%23ffffff%7C3px%2C1px+solid+%23999999&output=js"></script>
Make sure to replace the YourChannelName with your actual channel name.
For example: if your channel name were CaliChick94066 your channel embed code would be:
<script src="http://www.gmodules.com/ig/ifr?url=http://www.google.com/ig/modules/youtube.xml&up_channel=CaliChick94066&synd=open&w=320&h=390&title=&border=%23ffffff%7C3px%2C1px+solid+%23999999&output=js"></script>
Please look at the following links:
You just have to name the URL to your channel name. Also you can play with the height and the border color and size. Hope it helps

Can't get exactly what you are asking but if you are using an aggregate SUM function which implies that you are grouping the table.
The query goes for MYSQL like this
Select IFNULL(SUM(COLUMN1),0) as total from mytable group by condition
I think the pattern priestc mentions is more likely to be the usual cause of this issue when using PostgreSQL.
However I feel there are valid uses for the pattern and I don't think this issue should be a reason to always avoid it. For example:
try:
profile = user.get_profile()
except ObjectDoesNotExist:
profile = make_default_profile_for_user(user)
do_something_with_profile(profile)
If you do feel OK with this pattern, but want to avoid explicit transaction handling code all over the place then you might want to look into turning on autocommit mode (PostgreSQL 8.2+): https://docs.djangoproject.com/en/dev/ref/databases/#autocommit-mode
DATABASES['default'] = {
#.. you usual options...
'OPTIONS': {
'autocommit': True,
}
}

Check if you have multiple versions of the npm
command in your system path variable.
In my case, I had a version in the Node install directory and an older one in the npm globals
install directory (called prefix
in the npm config file). So I checked npm config get prefix
for the location and deleted the link and the npm
folder from node_modules. (Deleting the other one might also work, depending on the order in your PATH variable.)

It might rise parsing exceptions or have some unexpected behaviour.

Here is the most simple way.
import tkinter as tk
root = tk.Tk()
root.geometry('200x200')
root.resizable(width=0, height=0)
root.mainloop()
I don't think there is anything to specify. It's pretty straight forward.
if not integer set 0
<input type="text" id="min-value" />
$('#min-value').change(function ()
{
var checkvalue = $('#min-value').val();
if (checkvalue != parseInt(checkvalue))
$('#min-value').val(0);
});
The error you receive is from another method than the one you show here. It's a method that takes a parameter with the name "source". In your Visual Studio Options dialog, disable "Just my code", disable "Step over properties and operators" and enable "Enable .NET Framework source stepping". Make sure the .NET symbols can be found. Then the debugger will break inside the .NET method if it isn't your own. then check the stacktrace to find which value is passed that's null, but shouldn't.
What you should look for is a value that becomes null
and prevent that. From looking at your code, it may be the itemsal.Add
line that breaks.
Since you seem to have trouble with debugging in general and LINQ especially, let's try to help you out step by step (also note the expanded first section above if you still want to try it the classic way, I wasn't complete the first time around):
null
with something deliberately not null
;First make the code a bit more readable by splitting it in manageable pieces:
// in your using-section, add this:
using Roundsman.BAL;
// keep this in your normal location
var nCounts = from sale in sal
select new
{
SaleID = sale.OrderID,
LineItem = GetLineItem(sale.LineItems)
};
foreach (var item in nCounts)
{
foreach (var itmss in item.LineItem)
{
itemsal.Add(CreateWeeklyStockList(itmss));
}
}
// add this as method somewhere
WeeklyStockList CreateWeeklyStockList(LineItem lineItem)
{
string name = itmss.Item.Name.ToString(); // isn't Name already a string?
string code = itmss.Item.Code.ToString(); // isn't Code already a string?
string description = itmss.Item.Description.ToString(); // isn't Description already a string?
int quantity = Convert.ToInt32(itmss.Item.Quantity); // wouldn't (int) or "as int" be enough?
return new WeeklyStockList(
name,
code,
description,
quantity,
2, 2, 2, 2, 2, 2, 2, 2, 2
);
}
// also add this as a method
LineItem GetLineItem(IEnumerable<LineItem> lineItems)
{
// add a null-check
if(lineItems == null)
throw new ArgumentNullException("lineItems", "Argument cannot be null!");
// your original code
from sli in lineItems
group sli by sli.Item into ItemGroup
select new
{
Item = ItemGroup.Key,
Weeks = ItemGroup.Select(s => s.Week)
}
}
The code above is from the top of my head, of course, because I cannot know what type of classes you have and thus cannot test the code before posting. Nevertheless, if you edit it until it is correct (if it isn't so out of the box), then you already stand a large chance the actual error becomes a lot clearer. If not, you should at the very least see a different stacktrace this time (which we still eagerly await!).
The next step is to meticulously replace each part that can result in a null reference exception. By that I mean that you replace this:
select new
{
SaleID = sale.OrderID,
LineItem = GetLineItem(sale.LineItems)
};
with something like this:
select new
{
SaleID = 123,
LineItem = GetLineItem(new LineItem(/*ctor params for empty lineitem here*/))
};
This will create rubbish output, but will narrow the problem down even further to your potential offending line. Do the same as above for other places in the LINQ statements that can end up null
(just about everything).
This step you'll have to do yourself. But if LINQ fails and gives you such headaches and such unreadable or hard-to-debug code, consider what would happen with the next problem you encounter? And what if it fails on a live environment and you have to solve it under time pressure=
The moral: it's always good to learn new techniques, but sometimes it's even better to grab back to something that's clear and understandable. Nothing against LINQ, I love it, but in this particular case, let it rest, fix it with a simple loop and revisit it in half a year or so.
Actually, nothing to conclude. I went a bit further then I'd normally go with the long-extended answer. I just hope it helps you tackling the problem better and gives you some tools understand how you can narrow down hard-to-debug situations, even without advanced debugging techniques (which we haven't discussed).
Also:
func getTime() -> (hour: Int, minute: Int,second: Int) {
let hour = 1
let minute = 2
let second = 3
return ( hour, minute, second)
}
Then it's invoked as:
let time = getTime()
print("hour: \(time.hour), minute: \(time.minute), second: \(time.second)")
This is the standard way how to use it in the book The Swift Programming Language written by Apple.
or just like:
let time = getTime()
print("hour: \(time.0), minute: \(time.1), second: \(time.2)")
it's the same but less clearly.
This happened to work in my case:
$text = utf8_decode($text)
I turns the black diamond character into a question mark so you can:
$text = str_replace('?', '', utf8_decode($text));
You need a table variable:
declare @values table
(
Value varchar(1000)
)
insert into @values values ('A')
insert into @values values ('B')
insert into @values values ('C')
select blah
from foo
where myField in (select value from @values)
Make sure your refs for pushing are correct. This tutorial is pretty great, right from the documentation:
http://wiki.eclipse.org/EGit/User_Guide#GitHub_Tutorial
You can clone directly from GitHub, you choose where you clone that repository. And when you import that repository to Eclipse, you choose what refspec to push into upstream.
Click on the Git Repository workspace view, and make sure your remote refs are valid. Make sure you are pointing to the right local branch and pushing to the correct remote branch.
To get the value, we can use multiple attributes, one of them being the name attribute. E.g
$("input[name='nameOfElement']").val();
We can also use other attributes to get values
HTML
<input type="text" id="demoText" demo="textValue" />
JS
$("[demo='textValue']").val();
With the Sept 14, 2016 Angular 2.0.0 release, you are using still using HttpModule. Your main app.module.ts
would look something like this:
import { HttpModule } from '@angular/http';
@NgModule({
bootstrap: [ AppComponent ],
declarations: [ AppComponent ],
imports: [
BrowserModule,
HttpModule,
// ...more modules...
],
providers: [
// ...providers...
]
})
export class AppModule {}
Then in your app.ts
you can bootstrap as such:
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/main/app.module';
platformBrowserDynamic().bootstrapModule(AppModule);
It's not what the OP asked for (capturing groups) but you can extract the numbers using:
S='This is a sample 123 text and some 987 numbers'
echo "$S" | sed 's/ /\n/g' | sed -r '/([0-9]+)/ !d'
Gives the following:
123
987
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
while (phones.moveToNext())
{
String Name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)
String Number=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
Replace the line in htpasswd file:
go to: http://www.htaccesstools.com/htpasswd-generator-windows/
(if the link is expired, search another generator from google.com)
Enter your username and password. The site will generate encrypted line. Copy that line and replace it with the previous line in the file "repo/htpasswd".
You might also need to 'clear' the 'Authentication data' from tortoisSVN -> settings -> saved data
Tried and working. you are using,
<textarea name='Status'> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>
I am using javascript , (don't know about php), use id ="status" in textarea like
<textarea name='Status' id="status"> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>
then make a call to servlet sending the status to backend for updating using whatever strutucre(like MVC in java or anyother) you like, like this in your UI in script tag
<srcipt>
function UpdateStatus(){
//make an ajax call and get status value using the same 'id'
var var1= document.getElementById("status").value;
$.ajax({
type:"GET",//or POST
url:'http://localhost:7080/ajaxforjson/Testajax',
// (or whatever your url is)
data:{data1:var1},
//can send multipledata like {data1:var1,data2:var2,data3:var3
//can use dataType:'text/html' or 'json' if response type expected
success:function(responsedata){
// process on data
alert("got response as "+"'"+responsedata+"'");
}
})
}
</script>
and jsp is like
the servlet will look like: //webservlet("/zcvdzv") is just for url annotation
@WebServlet("/Testajax")
public class Testajax extends HttpServlet {
private static final long serialVersionUID = 1L;
public Testajax() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String data1=request.getParameter("data1");
//do processing on datas pass in other java class to add to DB
// i am adding or concatenate
String data="i Got : "+"'"+data1+"' ";
System.out.println(" data1 : "+data1+"\n data "+data);
response.getWriter().write(data);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}
}

The simplest solution I have found is to wrap your Font Awesome Icon in an <a></a>

There are many other reasons. You should always initialize all member variables in the initialization list if possible.
UPDATE tblKit
SET number = REPLACE(number, 'KIT', 'CH')
WHERE number like 'KIT%'
or simply this if you are sure that you have no values like this CKIT002
UPDATE tblKit
SET number = REPLACE(number, 'KIT', 'CH')
Below is my script to find all the sessions connected to a database and you can check if those sessions are doing any I/O and there is an option to kill them.
The script shows also the status of each session.
Have a look below.

If you can do something like Digg/Stackoverflow where the users can downvote/mark obscene content... do so.
Then all you need to do is review the "naughty" users, and block them if they break the rules.
You can test if bool is defined in c99 stdbool.h with
#ifndef __bool_true_false_are_defined || __bool_true_false_are_defined == 0
//typedef or define here
#endif
For the odd positions, you probably want:
>>>> list_ = list(range(10))
>>>> print list_[1::2]
[1, 3, 5, 7, 9]
>>>>
Lambda expressions have a type of Action<parameters>
(in case they don't return a value) or Func<parameters,return>
(in case they have a return value). In your case you have two input parameters, and you need to return a value, so you should use:
Func<FullTimeJob, Student, FullTimeJob>
There's nothing wrong with your query, but you could also do it this way:
WITH internalQuery (Amount)
AS
(
SELECT (0)
FROM DocumentOutputItems
GROUP BY DocumentId, DocumentSessionId
)
SELECT COUNT(*) AS NumberOfDistinctRows
FROM internalQuery
You can create your own extension method to do this:
public static bool Contains(this string source, string toCheck, StringComparison comp)
{
return source != null && toCheck != null && source.IndexOf(toCheck, comp) >= 0;
}
And then call:
mystring.Contains(myStringToCheck, StringComparison.OrdinalIgnoreCase);
Just do
if (Attachment != null && Attachment.Length > 0)
From && Operator
The conditional-AND operator (&&) performs a logical-AND of its bool operands, but only evaluates its second operand if necessary.
Two things you could do I think...
Here's how you could do either:
$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.FileName = "notepad.exe"
$pinfo.RedirectStandardError = $true
$pinfo.RedirectStandardOutput = $true
$pinfo.UseShellExecute = $false
$pinfo.Arguments = ""
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start() | Out-Null
#Do Other Stuff Here....
$p.WaitForExit()
$p.ExitCode
OR
Start-Job -Name DoSomething -ScriptBlock {
& ping.exe somehost
Write-Output $LASTEXITCODE
}
#Do other stuff here
Get-Job -Name DoSomething | Wait-Job | Receive-Job
You can use one of the other answers.
while :;do ping -n -w1 -W1 -c1 10.21.11.81| grep -E "rtt|100%"| sed -e "s/^/`date` /g"; sleep 1; done
Or as function pingt
for your ~/.bashrc:
pingt() {
while :;do ping -n -w1 -W1 -c1 $1| grep -E "rtt|100%"| sed -e "s/^/`date` /g"; sleep 1; done
}
With the new feature WindowInsetsCompat
in androidx core release 1.5.0-alpha02 you could check the visibility of the soft keyboard easily as below
Quoting from reddit comment
val View.keyboardIsVisible: Boolean get() = WindowInsetsCompat .toWindowInsetsCompat(rootWindowInsets) .isVisible(WindowInsetsCompat.Type.ime())
Some note about backward compatibility, quoting from release notes
New Features
The
WindowInsetsCompat
APIs have been updated to those in the platform in Android 11. This includes the newime()
inset type, which allows checking the visibility and size of the on-screen keyboard.Some caveats about the
ime()
type, it works very reliably on API 23+ when your Activity is using theadjustResize
window soft input mode. If you’re instead using theadjustPan
mode, it should work reliably back to API 14.
References
Do this instead:
values = [[1,2,3],[4,5]]
for x in values:
if len(x) == 3:
print(x)
An Exception is checked, and a RuntimeException is unchecked.
Checked means that the compiler requires that you handle the exception in a catch, or declare your method as throwing it (or one of its superclasses).
Generally, throw a checked exception if the caller of the API is expected to handle the exception, and an unchecked exception if it is something the caller would not normally be able to handle, such as an error with one of the parameters, i.e. a programming mistake.
LogisticRegression
is not for regression but classification !
The Y
variable must be the classification class,
(for example 0
or 1
)
And not a continuous
variable,
that would be a regression problem.
I think you can use db.collection.distinct(fields,query)
You will be able to get the distinct values in your case for NetworkID.
It should be something like this :
Db.collection.distinct('NetworkID')
boolean is a primitive data type in Java and primitive data types can not be null like other primitives int, float etc, they should be containing default values if not assigned.
In Java, only objects can assigned to null, it means the corresponding object has no reference and so does not contain any representation in memory.
Hence If you want to work with object as null , you should be using Boolean class which wraps a primitive boolean type value inside its object.
These are called wrapper classes in Java
For Example:
Boolean bool = readValue(...); // Read Your Value
if (bool == null) { do This ...}
As an extension to existing answers. For those trying to continue a numbered list after something other than a code block. For example a second paragraph. Just indent the second paragraph by at least 1 space.

For workdays, Monday to Friday, you can do it with a single SELECT, like this:
DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME
SET @StartDate = '2008/10/01'
SET @EndDate = '2008/10/31'
SELECT
(DATEDIFF(dd, @StartDate, @EndDate) + 1)
-(DATEDIFF(wk, @StartDate, @EndDate) * 2)
-(CASE WHEN DATENAME(dw, @StartDate) = 'Sunday' THEN 1 ELSE 0 END)
-(CASE WHEN DATENAME(dw, @EndDate) = 'Saturday' THEN 1 ELSE 0 END)
If you want to include holidays, you have to work it out a bit...
To really get this clear, here's my for-beginners answer:
You inputed the arguments in the wrong order.
A keyword argument has this style:
nullable=True, unique=False
A fixed parameter should be defined: True, False, etc. A non-keyword argument is different:
name="Ricardo", fruit="chontaduro"
This syntax error asks you to first put name="Ricardo"
and all of its kind (non-keyword) before those like nullable=True.
Here is what worked for me.
To set the server anonymous to inherit from the app pool identity do the following..
HttpServerUtility.UrlEncode
will use HttpUtility.UrlEncode
internally. There is no specific difference. The reason for existence of Server.UrlEncode
is compatibility with classic ASP.

If you want to call an action from your JavaScript, one way is to embed your JavaScript code, inside your view (.cshtml
file for example), and then, use Razor, to create a URL of that action:
$(function(){
$('#sampleDiv').click(function(){
/*
While this code is JavaScript, but because it's embedded inside
a cshtml file, we can use Razor, and create the URL of the action
Don't forget to add '' around the url because it has to become a
valid string in the final webpage
*/
var url = '@Url.Action("ActionName", "Controller")';
});
});
create div with id name
var divCreator=function (id){
newElement=document.createElement("div");
newNode=document.body.appendChild(newElement);
newNode.setAttribute("id",id);
}
add text to div
var textAdder = function(id, text) {
target = document.getElementById(id)
target.appendChild(document.createTextNode(text));
}
test code
divCreator("div1");
textAdder("div1", "this is paragraph 1");
output
this is paragraph 1
I just did the following to change the type of an input:
$('#ID_of_element')[0].type = 'text';
and it works.
I was needing to do this because I was using jQuery UI datepickers' in an ASP NET Core 3.1 project and they were not working properly on Chromium-based browsers (see: https://stackoverflow.com/a/61296225/7420301).

You can use the class org.apache.commons.lang.StringEscapeUtils:
String s = StringEscapeUtils.unescapeHtml("Happy & Sad")
It is working.
It is not possible directly. You may as well write some preprocessor which can handle that.
If I understand it correctly then below are the things that can be helpful to achieve that:
Use a pre-processor which will run through your JS files for example looking for patterns like "@import somefile.js" and replace them with the content of the actual file. Nicholas Zakas(Yahoo) wrote one such library in Java which you can use (http://www.nczonline.net/blog/2009/09/22/introducing-combiner-a-javascriptcss-concatenation-tool/)
If you are using Ruby on Rails then you can give Jammit asset packaging a try, it uses assets.yml configuration file where you can define your packages which can contain multiple files and then refer them in your actual webpage by the package name.
Try using a module loader like RequireJS or a script loader like LabJs with the ability to control the loading sequence as well as taking advantage of parallel downloading.
JavaScript currently does not provide a "native" way of including a JavaScript file into another like CSS ( @import ), but all the above mentioned tools/ways can be helpful to achieve the DRY principle you mentioned. I can understand that it may not feel intuitive if you are from a Server-side background but this is the way things are. For front-end developers this problem is typically a "deployment and packaging issue".
Hope it helps.
UPDATE:
Time has changed, you can now remove (expire) TestFlight Builds as in this answer but you still cannot delete the build.
OLD:
I asked apple and here is their answer:
I understand you would like to remove a build from iTunes Connect as shown in your screenshot.
Please be advised this is expected behavior as you can remove a build from being the current build but you cannot delete it from iTunes Connect. For more information, please refer to the iTunes Connect Developer Guide: https://developer.apple.com/library/content/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/
So i just can't.
This is how I approached it. I did not want to "cross the bridge", as it has been removed from Xcode 6 beta 5 anyway, quick and dirty:
extension String {
// converting a string to double
func toDouble() -> Double? {
// split the string into components
var comps = self.componentsSeparatedByString(".")
// we have nothing
if comps.count == 0 {
return nil
}
// if there is more than one decimal
else if comps.count > 2 {
return nil
}
else if comps[0] == "" || comps[1] == "" {
return nil
}
// grab the whole portion
var whole = 0.0
// ensure we have a number for the whole
if let w = comps[0].toInt() {
whole = Double(w)
}
else {
return nil
}
// we only got the whole
if comps.count == 1 {
return whole
}
// grab the fractional
var fractional = 0.0
// ensure we have a number for the fractional
if let f = comps[1].toInt() {
// use number of digits to get the power
var toThePower = Double(countElements(comps[1]))
// compute the fractional portion
fractional = Double(f) / pow(10.0, toThePower)
}
else {
return nil
}
// return the result
return whole + fractional
}
// converting a string to float
func toFloat() -> Float? {
if let val = self.toDouble() {
return Float(val)
}
else {
return nil
}
}
}
// test it out
var str = "78.001"
if let val = str.toFloat() {
println("Str in float: \(val)")
}
else {
println("Unable to convert Str to float")
}
// now in double
if let val = str.toDouble() {
println("Str in double: \(val)")
}
else {
println("Unable to convert Str to double")
}
Since version 2.1 of the Maven Dependency Plugin, there is a dependency:get goal for this purpose. To make sure you are using the right version of the plugin, you'll need to use the "fully qualified name":
mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get \ -DrepoUrl=http://download.java.net/maven/2/ \ -Dartifact=robo-guice:robo-guice:0.4-SNAPSHOT
You can get raw data using below method. BTW, this pattern is for Java 6. If you are using Java 7 or newer, please consider try-with-resources pattern.
public String getJSON(String url, int timeout) {
HttpURLConnection c = null;
try {
URL u = new URL(url);
c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.setRequestProperty("Content-length", "0");
c.setUseCaches(false);
c.setAllowUserInteraction(false);
c.setConnectTimeout(timeout);
c.setReadTimeout(timeout);
c.connect();
int status = c.getResponseCode();
switch (status) {
case 200:
case 201:
BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
sb.append(line+"\n");
}
br.close();
return sb.toString();
}
} catch (MalformedURLException ex) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
} finally {
if (c != null) {
try {
c.disconnect();
} catch (Exception ex) {
Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
}
}
}
return null;
}
And then you can use returned string with Google Gson to map JSON to object of specified class, like this:
String data = getJSON("http://localhost/authmanager.php");
AuthMsg msg = new Gson().fromJson(data, AuthMsg.class);
System.out.println(msg);
There is a sample of AuthMsg class:
public class AuthMsg {
private int code;
private String message;
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
JSON returned by http://localhost/authmanager.php must look like this:
{"code":1,"message":"Logged in"}

Mottie's and Diego Vieira's response above is what we ended up using and should be the accepted answer now. However, before I noticed it, I wrote this little javascript function that doesn't rely on character codes...
var capsLockIsOnKeyDown = {shiftWasDownDuringLastChar: false,
capsLockIsOnKeyDown: function(event) {
var eventWasShiftKeyDown = event.which === 16;
var capsLockIsOn = false;
var shifton = false;
if (event.shiftKey) {
shifton = event.shiftKey;
} else if (event.modifiers) {
shifton = !!(event.modifiers & 4);
}
if (event.target.value.length > 0 && !eventWasShiftKeyDown) {
var lastChar = event.target.value[event.target.value.length-1];
var isAlpha = /^[a-zA-Z]/.test(lastChar);
if (isAlpha) {
if (lastChar.toUpperCase() === lastChar && lastChar.toLowerCase() !== lastChar
&& !event.shiftKey && !capsLockIsOnKeyDown.shiftWasDownDuringLastChar) {
capsLockIsOn = true;
}
}
}
capsLockIsOnKeyDown.shiftWasDownDuringLastChar = shifton;
return capsLockIsOn;
}
}
Then call it in an event handler like so capsLockIsOnKeyDown.capsLockIsOnKeyDown(event)
But again, we ended up just using @Mottie s and @Diego Vieira s response
Its Very simple
variable.GetType().Name
it will return your datatype of your variable
Test if your variable is an instance of numbers.Number
:
>>> import numbers
>>> import decimal
>>> [isinstance(x, numbers.Number) for x in (0, 0.0, 0j, decimal.Decimal(0))]
[True, True, True, True]
This uses ABCs and will work for all built-in number-like classes, and also for all third-party classes if they are worth their salt (registered as subclasses of the Number
ABC).
However, in many cases you shouldn't worry about checking types manually - Python is duck typed and mixing somewhat compatible types usually works, yet it will barf an error message when some operation doesn't make sense (4 - "1"
), so manually checking this is rarely really needed. It's just a bonus. You can add it when finishing a module to avoid pestering others with implementation details.
This works starting with Python 2.6. On older versions you're pretty much limited to checking for a few hardcoded types.
There is obviously another process listening on the port. You might find out that process by using the following command:
$ lsof -i :8000
or change your tornado app's port. tornado's error info not Explicitly on this.
Just an update to the answer of @rafa.pereira.
Since ggplot2
is part of tidyverse
, it makes sense to use the convenient tidyverse functions to get rid of NAs.
library(tidyverse)
airquality %>%
drop_na(Ozone) %>%
ggplot(aes(x = Ozone))+
geom_bar(stat="bin")
Note that you can also use drop_na()
without columns specification; then all the rows with NAs in any column will be removed.
you can easily do like this:-
<table>
<thead>
<tr>
<th bgcolor="#5D7B9D"><font color="#fff">Header 1</font></th>
<th bgcolor="#5D7B9D"><font color="#fff">Header 2</font></th>
<th bgcolor="#5D7B9D"><font color="#fff">Header 3</font></th>
</tr>
</thead>
<tbody>
<tr>
<td>blah blah</td>
<td>blah blah</td>
<td>blah blah</td>
</tr>
</tbody>
</table>

Sometime Text of class A get overlap on class1 data because these both are in a single button tag. I try to break the tex using-
word-wrap: break-word; /* All browsers since IE 5.5+ */
overflow-wrap: break-word; /* Renamed property in CSS3 draft spec */
But this won't worked then I try this-
white-space: normal;

You can output special color control codes to get colored terminal output, here's a good resource on how to print colors.
For example:
printf("\033[22;34mHello, world!\033[0m"); // shows a blue hello world
EDIT: My original one used prompt color codes, which doesn't work :( This one does (I tested it).
Agree @Drixson Oseña: You should not write localhost/xampp/...., else write for e.g: localhost/mw-config/index.php
Try this one:
HTML:
<div id="para1"></div>
JavaScript:
document.getElementById("para1").innerHTML = formatAMPM();
function formatAMPM() {
var d = new Date(),
minutes = d.getMinutes().toString().length == 1 ? '0'+d.getMinutes() : d.getMinutes(),
hours = d.getHours().toString().length == 1 ? '0'+d.getHours() : d.getHours(),
ampm = d.getHours() >= 12 ? 'pm' : 'am',
months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
days = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];
return days[d.getDay()]+' '+months[d.getMonth()]+' '+d.getDate()+' '+d.getFullYear()+' '+hours+':'+minutes+ampm;
}

The CPP Section of the GCC Manual indicates that header files may be located in the following directories:
GCC looks in several different places for headers. On a normal Unix system, if you do not instruct it otherwise, it will look for headers requested with #include in:
/usr/local/include
libdir/gcc/target/version/include
/usr/target/include
/usr/include
For C++ programs, it will also look in /usr/include/g++-v3, first.
if you want to use "System.Data.Objects.EntityFunctions"
use "System.Data.Entity.DbFunctions" in EF 6.1+
I'd like to make some changes: In C, you can use the built in qsort command:
int compare( const void* a, const void* b)
{
int int_a = * ( (int*) a );
int int_b = * ( (int*) b );
// an easy expression for comparing
return (int_a > int_b) - (int_a < int_b);
}
qsort( a, 6, sizeof(int), compare )
For file Type you can rely on FileExtentions and for writing it to disk you can use BinaryWriter. or a FileStream.
Example (Assuming you already have a stream):
FileStream fileStream = File.Create(fileFullPath, (int)stream.Length);
// Initialize the bytes array with the stream length and then fill it with data
byte[] bytesInStream = new byte[stream.Length];
stream.Read(bytesInStream, 0, bytesInStream.Length);
// Use write method to write to the file specified above
fileStream.Write(bytesInStream, 0, bytesInStream.Length);
//Close the filestream
fileStream.Close();
Implement your Dropdown as
<select id = "dropdown" ref = {(input)=> this.menu = input}>
<option value="N/A">N/A</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select>
Now, to obtain the selected option value of the dropdown menu just use:
let res = this.menu.value;
Try using this code instead. Note: In the "from address" give your correct email id and password.
protected void btn_send_Click(object sender, EventArgs e)
{
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
mail.To.Add("to gmail address");
mail.From = new MailAddress("from gmail address", "Email head", System.Text.Encoding.UTF8);
mail.Subject = "This mail is send from asp.net application";
mail.SubjectEncoding = System.Text.Encoding.UTF8;
mail.Body = "This is Email Body Text";
mail.BodyEncoding = System.Text.Encoding.UTF8;
mail.IsBodyHtml = true;
mail.Priority = MailPriority.High;
SmtpClient client = new SmtpClient();
client.Credentials = new System.Net.NetworkCredential("from gmail address", "your gmail account password");
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
try
{
client.Send(mail);

NOTE: This answer is for SQL Server 2005. For SQL Server 2008 and later, there are much better methods as seen in the other answers.
You can use INSERT with SELECT UNION ALL:
INSERT INTO MyTable (FirstCol, SecondCol)
SELECT 'First' ,1
UNION ALL
SELECT 'Second' ,2
UNION ALL
SELECT 'Third' ,3
...
Only for small datasets though, which should be fine for your 4 records.

The solution we came to having a state that took 2 parameters was changing:
.state('somestate', {
url: '/somestate',
views: {...}
}
to
.state('somestate', {
url: '/somestate?id=:&sub=:',

I have ended up using ABCPdf from webSupergoo. It works really well and for about $350 it has saved me hours and hours based on your comments above. Thanks again Daniel and Bratch for your comments.
you cant do this. Use a custom popup. Something like with the help of jQuery UI or jQuery BOXY.

As per Where is Maven Installed on Ubuntu it will first create your settings.xml on /usr/share/maven2/, then you can copy to your home folder as jens mentioned
$ cp /usr/share/maven3/conf/settings.xml ~/.m2/settings.xml
function function_exists(function_name)
{
return eval('typeof ' + function_name) === 'function';
}
alert(function_exists('test'));
alert(function_exists('function_exists'));
OR
function function_exists(func_name) {
// discuss at: http://phpjs.org/functions/function_exists/

if (typeof func_name === 'string') {
func_name = this.window[func_name];
}
return typeof func_name === 'function';
}
There are a few ways to do this.
Using char struct (to string and back again)
string _stringOfA = char.ConvertFromUtf32(65);
int _asciiOfA = char.ConvertToUtf32("A", 0);
Simply casting the value (char and string shown)
char _charA = (char)65;
string _stringA = ((char)65).ToString();
Using ASCIIEncoding.
This can be used in a loop to do a whole array of bytes
var _bytearray = new byte[] { 65 };
ASCIIEncoding _asiiencode = new ASCIIEncoding();
string _alpha = _asiiencode .GetString(_newByte, 0, 1);
You can override the type converter class, this would allow you to do some fancy validation of the values:
var _converter = new ASCIIConverter();
string _stringA = (string)_converter.ConvertFrom(65);
int _intOfA = (int)_converter.ConvertTo("A", typeof(int));
Here is the Class:
public class ASCIIConverter : TypeConverter
{
// Overrides the CanConvertFrom method of TypeConverter.
// The ITypeDescriptorContext interface provides the context for the
// conversion. Typically, this interface is used at design time to
// provide information about the design-time container.
public override bool CanConvertFrom(ITypeDescriptorContext context,
Type sourceType)
{
if (sourceType == typeof(string))
{
return true;
}
return base.CanConvertFrom(context, sourceType);
}
public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)
{
if (destinationType == typeof(int))
{
return true;
}
return base.CanConvertTo(context, destinationType);
}
// Overrides the ConvertFrom method of TypeConverter.
public override object ConvertFrom(ITypeDescriptorContext context,
CultureInfo culture, object value)
{
if (value is int)
{
//you can validate a range of int values here
//for instance
//if (value >= 48 && value <= 57)
//throw error
//end if
return char.ConvertFromUtf32(65);
}
return base.ConvertFrom(context, culture, value);
}
// Overrides the ConvertTo method of TypeConverter.
public override object ConvertTo(ITypeDescriptorContext context,
CultureInfo culture, object value, Type destinationType)
{
if (destinationType == typeof(int))
{
return char.ConvertToUtf32((string)value, 0);
}
return base.ConvertTo(context, culture, value, destinationType);
}
}
Following document published by W3C also describes the differences between SOAP 1.1 and 1.2:
Yahoo uses a method called Sender ID, which can be configured at The SPF Setup Wizard and entered in to your DNS. Also one of the important ones for Exchange, Hotmail, AOL, Yahoo, and others is to have a Reverse DNS for your domain. Those will knock out most of the issues. However you can never prevent a person intentionally blocking your or custom rules.
You can use the event.target.result to reset the input from a component directly.
event.target.value = ""
This is my json data:
[
{
"name":"Test",
"value":"TestValue"
},
{
"name":"Test",
"value":"TestValue"
}
]
Powershell script:
$data = Get-Content "Path to json file" | Out-String | ConvertFrom-Json
foreach ($line in $data) {
$line.name
}
PHPMailer has the ability to automatically embed images from your HTML email. You have to give full path in the file system, when writing your HTML:
<img src="/var/www/host/images/photo.png" alt="my photo" />
It will automaticaly convert to:
<img src="cid:photo.png" alt="my photo" />
Steps:
I got it
Cells(1, 1).Value = StartDate
Cells(1, 1).NumberFormat = "dd/mm/yyyy"
Basically, I need to set the cell format, instead of setting the date.
Here is the Vanilla JavaScript solution for this issue -
First, we'll use Array.prototype.forEach()
method, as
document.querySelectorAll('input[type=file]')
returns an array like object.
Then we'll use the Function.prototype.call()
method to assign each element in the array-like object to the this
value in the .forEach
method.
HTML
<form id="myForm">
<input type="file" name="myFile" id="myFile_1">
<input type="file" name="myFile" id="myFile_2">
<input type="file" name="myFile" id="myFile_3">
<button type="button" onclick="saveData()">Save</button>
</form>
JavaScript
function saveData(){
var data = new FormData(document.getElementById("myForm"));
var inputs = document.querySelectorAll('input[type=file]');
Array.prototype.forEach.call(inputs[0].files, function(index){
data.append('files', index);
});
console.log(data.getAll("myFile"));
}
You can view the working example of the same HERE
Sys.sleep() will not work if the CPU usage is very high; as in other critical high priority processes are running (in parallel).
This code worked for me. Here I am printing 1 to 1000 at a 2.5 second interval.
for (i in 1:1000)
{
print(i)
date_time<-Sys.time()
while((as.numeric(Sys.time()) - as.numeric(date_time))<2.5){} #dummy while loop
}
Since AngularJS 1.5 we should use $onInit
which is available on any AngularJS component. Taken from the component lifecycle documentation since v1.5 its the preffered way:
$onInit() - Called on each controller after all the controllers on an element have been constructed and had their bindings initialized (and before the pre & post linking functions for the directives on this element). This is a good place to put initialization code for your controller.
var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl', function ($scope) {
//default state
$scope.name = '';
//all your init controller goodness in here
this.$onInit = function () {
$scope.name = 'Superhero';
}
});
The component lifecycle gives us the ability to handle component stuff in a good way. It allows us to create events for e.g. "init", "change" or "destroy" of an component. In that way we are able to manage stuff which is depending on the lifecycle of an component. This little example shows to register & unregister an $rootScope
event listener $on
. By knowing, that an event $on
binded on $rootScope
will not be undinded when the controller loses its reference in the view or getting destroyed we need to destroy a $rootScope.$on
listener manually. A good place to put that stuff is $onDestroy
lifecycle function of an component:
var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl', function ($scope, $rootScope) {
var registerScope = null;
this.$onInit = function () {
//register rootScope event
registerScope = $rootScope.$on('someEvent', function(event) {
console.log("fired");
});
}
this.$onDestroy = function () {
//unregister rootScope event by calling the return function
registerScope();
}
});
You can set the width in pixels via inline styling:
<input type="text" name="text" style="width: 195px;">
You can also set the width with a visible character length:
<input type="text" name="text" size="35">
As other answers have mentioned, the following calls will compute the hash:
MD5Context md5;
MD5Init(&md5);
MD5Update(&md5, data, datalen);
MD5Final(digest, &md5);
The purpose of splitting it up into that many functions is to let you stream large datasets.
For example, if you're hashing a 10GB file and it doesn't fit into ram, here's how you would go about doing it. You would read the file in smaller chunks and call MD5Update
on them.
MD5Context md5;
MD5Init(&md5);
fread(/* Read a block into data. */)
MD5Update(&md5, data, datalen);
fread(/* Read the next block into data. */)
MD5Update(&md5, data, datalen);
fread(/* Read the next block into data. */)
MD5Update(&md5, data, datalen);
...
// Now finish to get the final hash value.
MD5Final(digest, &md5);
You can use the excellent jquery-Json plugin:
http://code.google.com/p/jquery-json/
Makes it easy to convert to and from Json objects.
first to check whether the key already exists
a={1:2,3:4}
a.get(1)
2
a.get(5)
None
then you can add the new key and value
Using regex:
var str = "my car is red";
var stringArray = str.split(/(\s+)/);
console.log(stringArray); // ["my", " ", "car", " ", "is", " ", "red"]
\s
matches any character that is a whitespace, adding the plus makes it greedy, matching a group starting with characters and ending with whitespace, and the next group starts when there is a character after the whitespace etc.
Another solution is to put data definition into a separate file.
The idea is to write data common for both model and migration into a separate file, then require it in both the migration and the model. Then in the model we can add validations, while the migration is already good to go.
In order to not clutter this post with tons of code i wrote a GitHub gist.
See it here: https://gist.github.com/igorvolnyi/f7989fc64006941a7d7a1a9d5e61be47
I´ve found two problems with your Fiddle, one of the problems is first in Zeta´s answer.
the method is not toDataUrl();
is toDataURL();
and you forgot to store the canvas in your variable.
So the Fiddle now works fine http://jsfiddle.net/gfyWK/12/
I hope this helps!
Generally, it's considered a bad practice to style standard form controls because the output looks so different on each browser. See: http://www.456bereastreet.com/lab/styling-form-controls-revisited/select-single/ for some rendered examples.
That being said, I've had some luck making the background color an RGBA value:
<!DOCTYPE html>
<html>
<head>
<style>
body {
background: #d00;
}
select {
background: rgba(255,255,255,0.1) url('http://www.google.com/images/srpr/nav_logo6g.png') repeat-x 0 0;
padding:4px;
line-height: 21px;
border: 1px solid #fff;
}
</style>
</head>
<body>
<select>
<option>Foo</option>
<option>Bar</option>
<option>Something longer</option>
</body>
</html>
Google Chrome still renders a gradient on top of the background image in the color that you pass to rgba(r,g,b,0.1) but choosing a color that compliments your image and making the alpha 0.1 reduces the effect of this.
To answer this point:
I want Sleep to be an async method so it can await other methods
you can maybe rewrite the Sleep
function like this:
private static async Task<int> Sleep(int ms)
{
Console.WriteLine("Sleeping for " + ms);
var task = Task.Run(() => Thread.Sleep(ms));
await task;
Console.WriteLine("Sleeping for " + ms + "END");
return ms;
}
static void Main(string[] args)
{
Console.WriteLine("Starting");
var task1 = Sleep(2000);
var task2 = Sleep(1000);
int totalSlept = task1.Result +task2.Result;
Console.WriteLine("Slept for " + totalSlept + " ms");
Console.ReadKey();
}
running this code will output :
Starting
Sleeping for 2000
Sleeping for 1000
*(one second later)*
Sleeping for 1000END
*(one second later)*
Sleeping for 2000END
Slept for 3000 ms
So, as was mentioned in a couple comments containing the data in an array is simpler but the solution does not scale well in terms of efficiency as the data set size increases. You really should only use an iterator when you want to access a random object in the array, otherwise, generators are the way to go. Below I have prototyped a reader function which reads each json object individually and returns a generator.
The basic idea is to signal the reader to split on the carriage character "\n"
(or "\r\n"
for Windows). Python can do this with the file.readline()
function.
import json
def json_reader(filename):
with open(filename) as f:
for line in f:
yield json.loads(line)
However, this method only really works when the file is written as you have it -- with each object separated by a newline character. Below I wrote an example of a writer that separates an array of json objects and saves each one on a new line.
def json_writer(file, json_objects):
with open(file, "w") as f:
for jsonobj in json_objects:
jsonstr = json.dumps(jsonobj)
f.write(jsonstr + "\n")
You could also do the same operation with file.writelines()
and a list comprehension:
...
json_strs = [json.dumps(j) + "\n" for j in json_objects]
f.writelines(json_strs)
...
And if you wanted to append the data instead of writing a new file just change open(file, "w")
to open(file, "a")
.
In the end I find this helps a great deal not only with readability when I try and open json files in a text editor but also in terms of using memory more efficiently.
On that note if you change your mind at some point and you want a list out of the reader, Python allows you to put a generator function inside of a list and populate the list automatically. In other words, just write
lst = list(json_reader(file))
Using your data:
test_data <- data.frame(
var0 = 100 + c(0, cumsum(runif(49, -20, 20))),
var1 = 150 + c(0, cumsum(runif(49, -10, 10))),
Dates = seq.Date(as.Date("2002-01-01"), by="1 month", length.out=100))
I create a stacked version which is what ggplot()
would like to work with:
stacked <- with(test_data,
data.frame(value = c(var0, var1),
variable = factor(rep(c("Var0","Var1"),
each = NROW(test_data))),
Dates = rep(Dates, 2)))
In this case producing stacked
was quite easy as we only had to do a couple of manipulations, but reshape()
and the reshape
and reshape2
might be useful if you have a more complex real data set to manipulate.
Once the data are in this stacked form, it only requires a simple ggplot()
call to produce the plot you wanted with all the extras (one reason why higher-level plotting packages like lattice
and ggplot2
are so useful):
require(ggplot2)
p <- ggplot(stacked, aes(Dates, value, colour = variable))
p + geom_line()
I'll leave it to you to tidy up the axis labels, legend title etc.

Look at the dba_blockers
, dba_waiters
and dba_locks
for locking. The names should be self explanatory.
You could create a job that runs, say, once a minute and logged the values in the dba_blockers
and the current active sql_id
for that session. (via v$session
and v$sqlstats
).
You may also want to look in v$sql_monitor
. This will be default log all SQL that takes longer than 5 seconds. It is also visible on the "SQL Monitoring" page in Enterprise Manager.
Your git URL might have changed. Change the URL in the local directory by using the following command
for https protocol
git remote set-url origin https://github.com/username/repository.git
for ssh protocol
git remote set-url origin [email protected]:username/repository.git
//*[text()='ABC']
returns
<street>ABC</street>
<comment>BLAH BLAH BLAH <br><br>ABC</comment>
Just looking at the documentation it seems you should just declare a buffer of type []byte and pass it to read which will then read up to that many characters and return the number of characters actually read (and an error).
The docs say
Read reads up to len(b) bytes from the File. It returns the number of bytes read and an Error, if any. EOF is signaled by a zero count with err set to EOF.
Does that not work?
EDIT: Also, I think you should perhaps use the Reader/Writer interfaces declared in the bufio package instead of using os package.
In my case it wouldn't enough to include only map and promise:
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/toPromise';
I solved this problem by importing several rxjs components as official documentation recommends:
1) Import statements in one app/rxjs-operators.ts file:
// import 'rxjs/Rx'; // adds ALL RxJS statics & operators to Observable
// See node_module/rxjs/Rxjs.js
// Import just the rxjs statics and operators we need for THIS app.
// Statics
import 'rxjs/add/observable/throw';
// Operators
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/debounceTime';
import 'rxjs/add/operator/distinctUntilChanged';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/switchMap';
import 'rxjs/add/operator/toPromise';
2) Import rxjs-operator itself in your service:
// Add the RxJS Observable operators we need in this app.
import './rxjs-operators';

Did you check your Project Properties -> Project Facets
panel? (From that post)
A WTP project is composed of multiple units of functionality (known as facets).
The Java facet version needs to always match the java compiler compliance level.
The best way to change java level is to use the Project Facets properties panel as that will update both places at the same time.
The "
Project->Preferences->Project Facets
" stores its configuration in this file, "org.eclipse.wst.common.project.facet.core.xml
", under the ".settings
" directory.The content might look like this
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<runtime name="WebSphere Application Server v6.1"/>
<fixed facet="jst.java"/>
<fixed facet="jst.web"/>
<installed facet="jst.java" version="5.0"/>
<installed facet="jst.web" version="2.4"/>
<installed facet="jsf.ibm" version="7.0"/>
<installed facet="jsf.base" version="7.0"/>
<installed facet="web.jstl" version="1.1"/>
</faceted-project>
Check also your Java compliance level:
So we are all doing the same home work?
Strange how the most up-voted answer is wrong. Remember, draw/fillOval take height and width as parameters, not the radius. So to correctly draw and center a circle with user-provided x, y, and radius values you would do something like this:
public static void drawCircle(Graphics g, int x, int y, int radius) {
int diameter = radius * 2;
//shift x and y by the radius of the circle in order to correctly center it
g.fillOval(x - radius, y - radius, diameter, diameter);
}
I find that if I specify .row:nth-of-type(..)
, my other row's elements (for other formatting, etc) also get alternating colours. So rather, I'd define in my css an entirely new class:
.row-striped:nth-of-type(odd){
background-color: #efefef;
}
.row-striped:nth-of-type(even){
background-color: #ffffff;
}
So now, the alternating row colours will only apply to the row container, when I specify its class as .row-striped
, and not the elements inside the row
.
<!-- this entire row container is #efefef -->
<div class="row row-striped">
<div class="form-group">
<div class="col-sm-8"><h5>Field Greens with strawberry vinegrette</h5></div>
<div class="col-sm-4">
<input type="number" type="number" step="1" min="0"></input><small>$30/salad</small>
</div>
</div>
</div>
<!-- this entire row container is #ffffff -->
<div class="row row-striped">
<div class="form-group">
<div class="col-sm-8"><h5>Greek Salad</h5></div>
<div class="col-sm-4">
<input type="number" type="number" step="1" min="0"></input><small>$25/salad</small>
</div>
</div>
</div>
When a assembly' s AssemblyVersion is changed, If it has strong name, the referencing assemblies need to be recompiled, otherwise the assembly does not load! If it does not have strong name, if not explicitly added to project file, it will not be copied to output directory when build so you may miss depending assemblies, especially after cleaning the output directory.
You can use []
to extract values from a QueryDict
object like you would any ordinary dictionary.

For fpdf to work properly, there cannot be any output at all beside what fpdf generates. For example, this will work:
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
While this will not (note the leading space before the opening <?
tag)
<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
Also, this will not work either (the echo
will break it):
<?php
echo "About to create pdf";
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>
I'm not sure about the drupal side of things, but I know that absolutely zero non-fpdf output is a requirement for fpdf to work.
add ob_start ();
at the top and at the end add ob_end_flush();
<?php
ob_start();
require('fpdf.php');
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
ob_end_flush();
?>
give me an error as below:
FPDF error: Some data has already been output, can't send PDF
to over come this error:
go to fpdf.php
in that,goto line number 996
function Output($name='', $dest='')
after that make changes like this:
function Output($name='', $dest='') {
ob_clean(); //Output PDF to so
Hi do you have a session header on the top of your page. or any includes If you have then try to add this codes on top pf your page it should works fine.

In my case i had set:
ini_set('display_errors', 'on');
error_reporting(E_ALL | E_STRICT);
When i made the request to generate the report, some warnings were displayed in the browser (like the usage of deprecated functions).
Turning off
the display_errors
option, the report was generated successfully.
AJAX requests are no different from GET and POST requests initiated through a <form>
element. Which means you can use $_GET and $_POST to retrieve the data.
When you're making an AJAX request (jQuery example):
// JavaScript file
elements = [1, 2, 9, 15].join(',')
$.post('/test.php', {elements: elements})
It's (almost) equivalent to posting this form:
<form action="/test.php" method="post">
<input type="text" name="elements" value="1,2,9,15">
</form>
In both cases, on the server side you can read the data from the $_POST variable:
// test.php file
$elements = $_POST['elements'];
$elements = explode(',', $elements);
For the sake of simplicity I'm joining the elements with comma here. JSON serialization is a more universal solution, though.
public static void main(String[] args) {
HttpHeaders httpHeaders = new HttpHeaders();
httpHeaders.set("Accept", MediaType.APPLICATION_JSON_VALUE);
final String url = "https://host:port/contract/{code}";
Map<String, String> params = new HashMap<String, String>();
params.put("code", "123456");
HttpEntity<?> httpEntity = new HttpEntity<>(httpHeaders);
RestTemplate restTemplate = new RestTemplate();
restTemplate.exchange(url, HttpMethod.GET, httpEntity,String.class, params);
}
If you have many fields in select statement and you want latest value for all of those fields through optimized code:
select * from
(select * from table_name
order by id,rev desc) temp
group by id
@last_run_time
is a 9.4. User-Defined Variables and last_run_time datetime
one 13.6.4.1. Local Variable DECLARE Syntax, are different variables.
Try: SELECT last_run_time;
UPDATE
Example:
/* CODE FOR DEMONSTRATION PURPOSES */
DELIMITER $$
CREATE PROCEDURE `sp_test`()
BEGIN
DECLARE current_procedure_name CHAR(60) DEFAULT 'accounts_general';
DECLARE last_run_time DATETIME DEFAULT NULL;
DECLARE current_run_time DATETIME DEFAULT NOW();
-- Define the last run time
SET last_run_time := (SELECT MAX(runtime) FROM dynamo.runtimes WHERE procedure_name = current_procedure_name);
-- if there is no last run time found then use yesterday as starting point
IF(last_run_time IS NULL) THEN
SET last_run_time := DATE_SUB(NOW(), INTERVAL 1 DAY);
END IF;
SELECT last_run_time;
-- Insert variables in table2
INSERT INTO table2 (col0, col1, col2) VALUES (current_procedure_name, last_run_time, current_run_time);
END$$
DELIMITER ;
You do not specify why you think it is wrong but I can se two dangers:
BETWEEN can be implemented differently in different databases sometimes it is including the border values and sometimes excluding, resulting in that 1 and 31 of january would end up NOTHING. You should test how you database does this.
Also, if RATE_DATE contains hours also 2010-01-31 might be translated to 2010-01-31 00:00 which also would exclude any row with an hour other that 00:00.
One already exists. If you cannot get over the "Move" syntax of the System.IO
namespace. There is a static class FileSystem
within the Microsoft.VisualBasic.FileIO namespace that has both a RenameDirectory
and RenameFile
already within it.
As mentioned by SLaks, this is just a wrapper for Directory.Move
and File.Move
.
Should be something to do with your Platform Settings. Try the below steps
Just as most have said, but dont forget to set LifeCycleOwner
Sample in Java
i.e
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
BindingClass binding = DataBindingUtil.inflate(inflater, R.layout.fragment_layout, container, false);
ModelClass model = ViewModelProviders.of(getActivity()).get(ViewModelClass.class);
binding.setLifecycleOwner(getActivity());
binding.setViewmodelclass(model);
//Your codes here
return binding.getRoot();
}
I wrote rabbitmq-dump-queue which allows dumping messages from a RabbitMQ queue to local files and requeuing the messages in their original order.

For digits you can use
if (ch >= '0' && ch <= '9')
{
/*It is a digit*/
}
But since characters in C are internally treated as ASCII values you can also use ASCII values to check the same.
In Java, you just throw the exception you caught, so throw e
rather than just throw
. Java maintains the stack trace.
one more, after you create user by following cmd-1, please assign read/write/root role to the user by cmd-2. then restart mongodb by cmd "mongod --auth".
The benefit of assign role to the user is you can do read/write operation by mongo shell or python/java and so on, otherwise you will meet "pymongo.errors.OperationFailure: not authorized" when you try to read/write your db.
cmd-1:
use admin
db.createUser({
user: "newUsername",
pwd: "password",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
})
cmd-2:
db.grantRolesToUser('newUsername',[{ role: "root", db: "admin" }])
I think the above mentioned answer is correct.Because == is for testing whether two strings are the same object,whereas .equals() tests whether two strings have the same value.
The STL's philosophy is that you choose a container based on guarantees and not based on how the container is implemented. For example, your choice of container may be based on a need for fast lookups. For all you care, the container may be implemented as a unidirectional list -- as long as searching is very fast you'd be happy. That's because you're not touching the internals anyhow, you're using iterators or member functions for the access. Your code is not bound to how the container is implemented but to how fast it is, or whether it has a fixed and defined ordering, or whether it is efficient on space, and so on.
I had a similar problem with HTML input fields in MVC. The web paged only showed the first keyword of the field. Example: input field: "The quick brown fox" Displayed value: "The"
The resolution was to put the variable in quotes in the value statement as follows:
<input class="ParmInput" type="text" id="respondingRangerUnit" name="respondingRangerUnit"
onchange="validateInteger(this.value)" value="@ViewBag.respondingRangerUnit">
you need to store the token while creating for 1st registration. When you retrieve data from login table you need to differentiate entered date with current date if it is more than 1 day (24 hours) you need to display message like your token is expired.

I use this code in my Mac app, the same or similar should work with the iPhone. It's based on the RegexKitLite regular expressions and turns the text red when its invalid.
static bool TextIsValidValue( NSString* newText, double &value )
{
bool result = false;
if ( [newText isMatchedByRegex:@"^(?:|0|[1-9]\\d*)(?:\\.\\d*)?$"] ) {
result = true;
value = [newText doubleValue];
}
return result;
}
- (IBAction) doTextChanged:(id)sender;
{
double value;
if ( TextIsValidValue( [i_pause stringValue], value ) ) {
[i_pause setTextColor:[NSColor blackColor]];
// do something with the value
} else {
[i_pause setTextColor:[NSColor redColor]];
}
}
As simple and works
title.ToLower().Contains("String".ToLower())
This solution works with special characters too, for instance é
, è
, ê
, ü
, ö
, à

Note: I posted the solution that uses global functions as it's probably the simplest to understand. But do look into "javascript module pattern" if you want better code (cleaner, easier to maintain and extend), see impressivewebs.com/my-current-javascript-design-pattern and also this YouTube video (presentation by Paul Irish).

This will work also when the string is invalid or does not contain flags etc:
function regExpFromString(q) {_x000D_
let flags = q.replace(/.*\/([gimuy]*)$/, '$1');_x000D_
if (flags === q) flags = '';_x000D_
let pattern = (flags ? q.replace(new RegExp('^/(.*?)/' + flags + '$'), '$1') : q);_x000D_
try { return new RegExp(pattern, flags); } catch (e) { return null; }_x000D_
}_x000D_
_x000D_
console.log(regExpFromString('\\bword\\b'));_x000D_
console.log(regExpFromString('\/\\bword\\b\/gi'));_x000D_
_x000D_
(2021-02) The following, surprisingly easy, solution worked for me:

"Rounded" down as in your example. This will return a varchar value of the date.
DECLARE @date As DateTime2
SET @date = '2007-09-22 15:07:38.850'
SELECT CONVERT(VARCHAR(16), @date, 120) --2007-09-22 15:07
SELECT CONVERT(VARCHAR(13), @date, 120) --2007-09-22 15
This code is already written. If you don't mind the (extremely) minor performance hit--which is probably no worse than doing a regex match--use Integer.parseInt() or Double.parseDouble(). That'll tell you right away if a String is only numbers (or is a number, as appropriate). If you need to handle longer strings of numbers, both BigInteger and BigDecimal sport constructors that accept Strings. Any of these will throw a NumberFormatException if you try to pass it a non-number (integral or decimal, based on the one you choose, of course). Alternately, depending on your requirements, just iterate the characters in the String and check Character.isDigit() and/or Character.isLetter().
A great way for cloning an array is with an array literal and the spread syntax. This is made possible by ES2015.
const objArray = [{name:'first'}, {name:'second'}, {name:'third'}, {name:'fourth'}];
const clonedArr = [...objArray];
console.log(clonedArr) // [Object, Object, Object, Object]
You can find this copy option in MDN's documentation: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator#Copy_an_array
It is also an Airbnb's best practice. https://github.com/airbnb/javascript#es6-array-spreads
Note: The spread syntax in ES2015 goes one level deep while copying an array. Therefore, they are unsuitable for copying multidimensional arrays.

new()
shouldn't be used as little as possible. It should be used as carefully as possible. And it should be used as often as necessary as dictated by pragmatism.
Allocation of objects on the stack, relying on their implicit destruction, is a simple model. If the required scope of an object fits that model then there's no need to use new()
, with the associated delete()
and checking of NULL pointers.
In the case where you have lots of short-lived objects allocation on the stack should reduce the problems of heap fragmentation.
However, if the lifetime of your object needs to extend beyond the current scope then new()
is the right answer. Just make sure that you pay attention to when and how you call delete()
and the possibilities of NULL pointers, using deleted objects and all of the other gotchas that come with the use of pointers.
This is an extension to Langdon's answer with a directive approach to the problem. If you're going to have multiple galleries on the page this may be one way to go about it without much fuss.
Usage:
<gallery images="items"></gallery>
<gallery images="cats"></gallery>
In a translation unit within the same namespace, usually at the top:
// foo.h
struct foo
{
static const std::string s;
};
// foo.cpp
const std::string foo::s = "thingadongdong"; // this is where it lives
// bar.h
namespace baz
{
struct bar
{
static const float f;
};
}
// bar.cpp
namespace baz
{
const float bar::f = 3.1415926535;
}
Just wanted to add an example of when you may need to use both. I am currently writing a file handler bound to a database model in a general purpose ERP solution.
This way, I get to have multiple templates for different files and a common set of interface methods with clear distinction. The interface gives the correct analogy to the access methods rather than what would have been with a base abstract class.
Further down the line when I will make adapters for different file storage services, this implementation will allow the interface to be used elsewhere in totally different contexts.
Well, it's fairly self-explanatory: you've run out of memory.
You may want to try starting it with more memory, using the -Xmx flag, e.g.
java -Xmx2048m [whatever you'd have written before]
This will use up to 2 gigs of memory.
See the non-standard options list for more details.
An alternative using perl would be:
perl -pe 's/(.*) (.*)$/$2/' file
where you may change \t
for whichever the delimiter of file
is
Robocopy, or "Robust File Copy", is a command-line directory and/or file replication command. Robocopy functionally replaces Xcopy, with more options. It has been available as part of the Windows Resource Kit starting with Windows NT 4.0, and was first introduced as a standard feature in Windows Vista and Windows Server 2008. The command is

<ImageView

With Mac OS X and the more recent versions of Acrobat Pro, the PDF printer option does not work. What does work is doing basically the same thing in Preview App. Open the multi page file in Preview, select File>Print. In the Print dialog set your sheet size as if you are using a printer. You may want to select "Auto Rotate", "Scale to Fit" and "Print Entire Image". Then in the lower left corner is the drop button "PDF" and in that menu select "Save as PDF". Give it a new file name, click Save and then you can open the resulting file in whatever PDF app you want and the sheet sizes are the same.
If you want the output to be
array([1.6e-01, 9.9e-01, 3.6e-04])
the problem is not really a missing feature of NumPy, but rather that this sort of rounding is not a standard thing to do. You can make your own rounding function which achieves this like so:
def my_round(value, N):
exponent = np.ceil(np.log10(value))
return 10**exponent*np.round(value*10**(-exponent), N)
For a general solution handling 0
and negative values as well, you can do something like this:
def my_round(value, N):
value = np.asarray(value).copy()
zero_mask = (value == 0)
value[zero_mask] = 1.0
sign_mask = (value < 0)
value[sign_mask] *= -1
exponent = np.ceil(np.log10(value))
result = 10**exponent*np.round(value*10**(-exponent), N)
result[sign_mask] *= -1
result[zero_mask] = 0.0
return result
Ignoring newlines is ignoring security and good coding. wnoise had the only good answer. Here is a variation on his that puts the filenames in an array $x
while IFS= read -rd ''; do
x+=("${REPLY#* }");
done < <(find . -maxdepth 1 -printf '%T@ %p\0' | sort -r -z -n )
Enums have been added to Python 3.4 as described in PEP 435. It has also been backported to 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4 on pypi.
For more advanced Enum techniques try the aenum library (2.7, 3.3+, same author as enum34
. Code is not perfectly compatible between py2 and py3, e.g. you'll need __order__
in python 2).
enum34
, do $ pip install enum34
aenum
, do $ pip install aenum
Installing enum
(no numbers) will install a completely different and incompatible version.
from enum import Enum # for enum34, or the stdlib version
# from aenum import Enum # for the aenum version
Animal = Enum('Animal', 'ant bee cat dog')
Animal.ant # returns <Animal.ant: 1>
Animal['ant'] # returns <Animal.ant: 1> (string lookup)
Animal.ant.name # returns 'ant' (inverse lookup)
or equivalently:
class Animal(Enum):
ant = 1
bee = 2
cat = 3
dog = 4
In earlier versions, one way of accomplishing enums is:
def enum(**enums):
return type('Enum', (), enums)
which is used like so:
>>> Numbers = enum(ONE=1, TWO=2, THREE='three')
>>> Numbers.ONE
1
>>> Numbers.TWO
2
>>> Numbers.THREE
'three'
You can also easily support automatic enumeration with something like this:
def enum(*sequential, **named):
enums = dict(zip(sequential, range(len(sequential))), **named)
return type('Enum', (), enums)
and used like so:
>>> Numbers = enum('ZERO', 'ONE', 'TWO')
>>> Numbers.ZERO
0
>>> Numbers.ONE
1
Support for converting the values back to names can be added this way:
def enum(*sequential, **named):
enums = dict(zip(sequential, range(len(sequential))), **named)
reverse = dict((value, key) for key, value in enums.iteritems())
enums['reverse_mapping'] = reverse
return type('Enum', (), enums)
This overwrites anything with that name, but it is useful for rendering your enums in output. It will throw KeyError if the reverse mapping doesn't exist. With the first example:
>>> Numbers.reverse_mapping['three']
'THREE'
If you are using mypy another way to express "enums" is with Literal.
For example
from typing import Literal #python >=3.8
from typing_extensions import Literal #python 2.7, 3.4-3.7
Animal = Literal['ant', 'bee', 'cat', 'dog']
def hello_animal(animal: Animal):
print(f"hello {animal}")
hello_animal('rock') # error
hello_animal('bee') # passes
I had the same problem at my office and I solved it adding the proxy in the destination of the R shortcut; clik on right button of the R icon, preferences, and in the destination field add
"C:\Program Files\R\your_R_version\bin\Rgui.exe" http_proxy=http://user_id:passwod@your_proxy:your_port/
Be sure to put the directory where you have the R program installed. That works for me. Hope this help.
You are using two WHERE
clauses but only one is allowed. Use it like this:
SELECT table1.f_id FROM table1
INNER JOIN table2 ON table2.f_id = table1.f_id
WHERE
table1.f_com_id = '430'
AND table1.f_status = 'Submitted'
AND table2.f_type = 'InProcess'
Just a small addition to Jeff Bowman's excellent answer, as I found this question when searching for a solution to one of my own problems:
If a call to a method matches more than one mock's when
trained calls, the order of the when
calls is important, and should be from the most wider to the most specific. Starting from one of Jeff's examples:
when(foo.quux(anyInt(), anyInt())).thenReturn(true);
when(foo.quux(anyInt(), eq(5))).thenReturn(false);
is the order that ensures the (probably) desired result:
foo.quux(3 /*any int*/, 8 /*any other int than 5*/) //returns true
foo.quux(2 /*any int*/, 5) //returns false
If you inverse the when calls then the result would always be true
.
I know the perfect answer:
I prefer going to windows character map and find a perfect hide like ?.
example:TextBox2.PasswordChar = '?';
You must specify which type the response is
this.productService.getProducts().subscribe(res => {
this.productsArray = res;
});
Try this
this.productService.getProducts().subscribe((res: Product[]) => {
this.productsArray = res;
});
mute=1
or muted=1
as suggested by @Fab will work. However, if you wish to enable autoplay with sound you should add allow="autoplay"
to your embedded <iframe>
.
<iframe type="text/html" src="https://www.youtube.com/embed/-ePDPGXkvlw?autoplay=1" frameborder="0" allow="autoplay"></iframe>
This is officially supported and documented in Google's Autoplay Policy Changes 2017 post
Iframe delegation A feature policy allows developers to selectively enable and disable use of various browser features and APIs. Once an origin has received autoplay permission, it can delegate that permission to cross-origin iframes with a new feature policy for autoplay. Note that autoplay is allowed by default on same-origin iframes.
<!-- Autoplay is allowed. --> <iframe src="https://cross-origin.com/myvideo.html" allow="autoplay"> <!-- Autoplay and Fullscreen are allowed. --> <iframe src="https://cross-origin.com/myvideo.html" allow="autoplay; fullscreen">
When the feature policy for autoplay is disabled, calls to play() without a user gesture will reject the promise with a NotAllowedError DOMException. And the autoplay attribute will also be ignored.
Pattern module in not available from django 1.8. So you need to remove pattern from your import and do something similar to the following:
from django.conf.urls import include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = [
# here we are not using pattern module like in previous django versions
url(r'^admin/', include(admin.site.urls)),
]
Rename your file, commit the changes including the "deleted" file, and don't include the new (renamed) file.
Rename your file back.
Try changing server name to "localhost"
pymssql.connect(server="localhost", user="myusername", password="mypwd", database="temp",port="1433")
For those looking to debug gradle dependencies in react-native
projects, the command is (executed from projectname/android
)
./gradlew app:dependencies --configuration compile
Personally, I'd use file_put_contents and file_get_contents (these are wrappers for fopen, fputs, etc).
Also, if you are going to write any structured data, such as arrays, I suggest you serialize and unserialize the files contents.
$file = '/tmp/file';
$content = serialize($my_variable);
file_put_contents($file, $content);
$content = unserialize(file_get_contents($file));
You can use
//send message only to sender-client
socket.emit('message', 'check this');
//or you can send to all listeners including the sender
io.emit('message', 'check this');
//send to all listeners except the sender
socket.broadcast.emit('message', 'this is a message');
//or you can send it to a room
socket.broadcast.to('chatroom').emit('message', 'this is the message to all');
You can also use shorthand for describe as desc
for table description.
desc [db_name.]table_name;
or
use db_name;
desc table_name;
You can also use explain
for table description.
explain [db_name.]table_name;

This happened to me when I was trying to push the develop branch (I am using git flow). Someone had push updates to master. to fix it I did:
git co master
git pull
Which fetched those changes. Then,
git co develop
git pull
Which didn't do anything. I think the develop branch already pushed despite the error message. Everything is up to date now and no errors.
There's also this if you prefer:
mysql_query('SHOW COLUMNS FROM tableName');
