Username + password is no longer a recommended solution. This is due to
I tried this and Gmail sent the email used as username in this code an email saying that We recently blocked a sign-in attempt to your Google Account, and directed me to this support page: support.google.com/accounts/answer/6010255 so it looks for it to work, the email account being used to send needs to reduce their own security
Google had released Gmail API - https://developers.google.com/gmail/api/?hl=en. We should use oAuth2 method, instead of username + password.

Inspite of many answers and almost same result. I would like to add my answer and explain its working. Because it is important to understand its working rather than copy pasting one line code. Generating random numbers is nothing but simple maths.
CODE:
function getR(lower, upper) {
var percent = (Math.random() * 100);
// this will return number between 0-99 because Math.random returns decimal number from 0-0.9929292 something like that
//now you have a percentage, use it find out the number between your INTERVAL :upper-lower
var num = ((percent * (upper - lower) / 100));
//num will now have a number that falls in your INTERVAL simple maths
num += lower;
//add lower to make it fall in your INTERVAL
//but num is still in decimal
//use Math.floor>downward to its nearest integer you won't get upper value ever
//use Math.ceil>upward to its nearest integer upper value is possible
//Math.round>to its nearest integer 2.4>2 2.5>3 both lower and upper value possible
console.log(Math.floor(num), Math.ceil(num), Math.round(num));
}
In addition to setting USB connection/storage mode to "Camera (PTP)", I also had to enable developer mode, which has been hidden since 4.2.
use this
public void goToAttract(View v)
{
Intent intent = new Intent(getActivity(), MainActivityList.class);
startActivity(intent);
}
be sure you've registered MainActivityList
in you Manifest
Collection is a interface which is used to represent group of individual object as a single entity.
Collections is an utility class present in java.util. package to define several utility method (like sorting,searching ) for collection object.
I always write a default method "findByIdOrError" in widely used CrudRepository repos/interfaces.
@Repository
public interface RequestRepository extends CrudRepository<Request, Integer> {
default Request findByIdOrError(Integer id) {
return findById(id).orElseThrow(EntityNotFoundException::new);
}
}
Branches are made of wood and grow from the trunk of the tree. Tags are made of paper (derivative of wood) and hang like Christmas Ornaments from various places in the tree.
Your project is the tree, and your feature that will be added to the project will grow on a branch. The answer is branch.
Another alternative is to set the root_path
which fixes the problem both for templates and static folders.
root_path = Path(sys.executable).parent if getattr(sys, 'frozen', False) else Path(__file__).parent
app = Flask(__name__.split('.')[0], root_path=root_path)
If you render templates directly via Jinja2
, then you write:
ENV = jinja2.Environment(loader=jinja2.FileSystemLoader(str(root_path / 'templates')))
template = ENV.get_template(your_template_name)
The current answers are a bit confusing and misleading, and they are missing some important DNS implications. I'll try to summarize where things stand clearly.
IDisposable
objects should ideally be disposed when you are done with them, especially those that own Named/shared OS resources. HttpClient
is no exception, since as Darrel Miller points out it allocates cancellation tokens, and request/response bodies can be unmanaged streams.Connection:close
header after DNS changes take place. Another possibility involves recycling the HttpClient
on the client side, either periodically or via some mechanism that learns about the DNS change. See https://github.com/dotnet/corefx/issues/11224 for more information (I suggest reading it carefully before blindly using the code suggested in the linked blog post).Spring Docs explain that
In proxy mode (which is the default), only external method calls coming in through the proxy are intercepted. This means that self-invocation, in effect, a method within the target object calling another method of the target object, will not lead to an actual transaction at runtime even if the invoked method is marked with @Transactional.
Consider the use of AspectJ mode (see mode attribute in table below) if you expect self-invocations to be wrapped with transactions as well. In this case, there will not be a proxy in the first place; instead, the target class will be weaved (that is, its byte code will be modified) in order to turn @Transactional into runtime behavior on any kind of method.
Another way is user BeanSelfAware
Use string
instead of string?
in all places in your code.
The Nullable<T>
type requires that T is a non-nullable value type, for example int
or DateTime
. Reference types like string
can already be null. There would be no point in allowing things like Nullable<string>
so it is disallowed.
Also if you are using C# 3.0 or later you can simplify your code by using auto-implemented properties:
public class WordAndMeaning
{
public string Word { get; set; }
public string Meaning { get; set; }
}
Since Joda is getting faded, someone might want to convert LocaltDate
to LocalDateTime
in Java 8. In Java 8 LocalDateTime
it will give a way to create a LocalDateTime
instance using a LocalDate
and LocalTime
. Check here.
public static LocalDateTime of(LocalDate date, LocalTime time)
Sample would be,
// just to create a sample LocalDate
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyyMMdd");
LocalDate ld = LocalDate.parse("20180306", dtf);
// convert ld into a LocalDateTime
// We need to specify the LocalTime component here as well, it can be any accepted value
LocalDateTime ldt = LocalDateTime.of(ld, LocalTime.of(0,0)); // 2018-03-06T00:00
Just for reference, For getting the epoch seconds below can be used,
ZoneId zoneId = ZoneId.systemDefault();
long epoch = ldt.atZone(zoneId).toEpochSecond();
// If you only care about UTC
long epochUTC = ldt.toEpochSecond(ZoneOffset.UTC);
I recommend, instead, updating the path in the associated script(s) (such as /usr/bin/yum) to point at your previous Python as the interpreter.
Ideally, you want to upgrade yum and its associated scripts so that they are supported by the default Python installed.
If that is not possible, the above is entirely workable and tested.
Change:
#!/usr/bin/python
to whatever the path is of your old version until you can make the above yum improvement.
Cases where you couldn't do the above are if you have an isolated machine, don't have the time to upgrade rpm manually or can't connect temporarily or permanently to a standard yum repository.
Try adding the property line-height: 22px;
to the code.
use this for all user
sudo chown -R $(whoami):$(whoami) /var/..
int values[] = { 23, 1, 5, 78, 22, 4};
int sum = 0;
for (int i = 0; i < values.length; i++)
sum += values[i];
double average = ((double) sum) / values.length;
you can access the children of a vuejs component with this.$children
. if you want to use the query selector on the current component instance then this.$el.querySelector(...)
just doing a simple console.log(this)
will show you all the properties of a vue component instance.
additionally if you know the element you want to access in your component, you can add the v-el:uniquename
directive to it and access it via this.$els.uniquename
Following up on the comment ron posted, here is the detailed solution. Let's say you have registered a repeating alarm with a pending intent like this:
Intent intent = new Intent("com.my.package.MY_UNIQUE_ACTION");
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0,
intent, PendingIntent.FLAG_UPDATE_CURRENT);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.MINUTE, 1);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000 * 60, pendingIntent);
The way you would check to see if it is active is to:
boolean alarmUp = (PendingIntent.getBroadcast(context, 0,
new Intent("com.my.package.MY_UNIQUE_ACTION"),
PendingIntent.FLAG_NO_CREATE) != null);
if (alarmUp)
{
Log.d("myTag", "Alarm is already active");
}
The key here is the FLAG_NO_CREATE
which as described in the javadoc: if the described PendingIntent **does not** already exists, then simply return null
(instead of creating a new one)
One options is: disabled this extension_dir = "ext"
and the other is:
go to wamp icon and see php and the click on php error logs then from error log u can find exact error.
this error occurs only if paths are not properly set.
You don't need !important
when modifying CSS with jQuery since it modifies the style
attribute on the elements in the DOM directly. !important
is only needed in stylesheets to disallow a particular style rule from being overridden at a lower level. Modifying style
directly is the lowest level you can go, so !important
has no meaning.
With Calendar it works as follows:
//create first Calendar object
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 15); // 3 PM
// the same is
calendar.set(Calendar.AM_PM, Calendar.PM); // choose PM mode
calendar.set(Calendar.HOUR, 3); // 3 PM
System.out.println( calendar.get(Calendar.HOUR) ); // AM_PM format
System.out.println( calendar.get(Calendar.HOUR_OF_DAY) ); // 0-23 format
for who needs complete example code. Right+Left added
var keyPressed = {};
document.addEventListener('keydown', function(e) {
keyPressed[e.key + e.location] = true;
if(keyPressed.Shift1 == true && keyPressed.Control1 == true){
// Left shift+CONTROL pressed!
keyPressed = {}; // reset key map
}
if(keyPressed.Shift2 == true && keyPressed.Control2 == true){
// Right shift+CONTROL pressed!
keyPressed = {};
}
}, false);
document.addEventListener('keyup', function(e) {
keyPressed[e.key + e.location] = false;
keyPressed = {};
}, false);
Indeed, thanks to the comments to my post here, it looks like sparse directories are the way to go. I believe the following should do it:
svn checkout --depth empty http://svnserver/trunk/proj
svn update --set-depth infinity proj/foo
svn update --set-depth infinity proj/bar
svn update --set-depth infinity proj/baz
Alternatively, --depth immediates
instead of empty
checks out files and directories in trunk/proj
without their contents. That way you can see which directories exist in the repository.
As mentioned in @zigdon's answer, you can also do a non-recursive checkout. This is an older and less flexible way to achieve a similar effect:
svn checkout --non-recursive http://svnserver/trunk/proj
svn update trunk/foo
svn update trunk/bar
svn update trunk/baz
A lot of answers ask you to use END
, but if that's not working for you, try:
text.delete("1.0", "end-1c")
you make the use of the HTML Helper and have
@using(Html.BeginForm())
{
Username: <input type="text" name="username" /> <br />
Password: <input type="text" name="password" /> <br />
<input type="submit" value="Login">
<input type="submit" value="Create Account"/>
}
or use the Url helper
<form method="post" action="@Url.Action("MyAction", "MyController")" >
Html.BeginForm
has several (13) overrides where you can specify more information, for example, a normal use when uploading files is using:
@using(Html.BeginForm("myaction", "mycontroller", FormMethod.Post, new {enctype = "multipart/form-data"}))
{
< ... >
}
If you don't specify any arguments, the Html.BeginForm()
will create a POST
form that points to your current controller and current action. As an example, let's say you have a controller called Posts
and an action called Delete
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
return View(model);
}
[HttpPost]
public ActionResult Delete(int id)
{
var model = db.GetPostById(id);
if(model != null)
db.DeletePost(id);
return RedirectToView("Index");
}
and your html page would be something like:
<h2>Are you sure you want to delete?</h2>
<p>The Post named <strong>@Model.Title</strong> will be deleted.</p>
@using(Html.BeginForm())
{
<input type="submit" class="btn btn-danger" value="Delete Post"/>
<text>or</text>
@Url.ActionLink("go to list", "Index")
}
It isn't built-in, but you can make a subclass of list that takes tuples as "indexes" if you'd like:
class MyList(list):
def __getitem__(self, index):
if isinstance(index, tuple):
return [self[i] for i in index]
return super(MyList, self).__getitem__(index)
seq = MyList("foo bar baaz quux mumble".split())
print seq[0]
print seq[2,4]
print seq[1::2]
printing
foo
['baaz', 'mumble']
['bar', 'quux']
In your StyleSheet, simply put:
width: '80%';
instead of:
width: 80%;
Keep Coding........ :)
example.php:
<?php
if(!isset($_GET['app_link'])){ ?>
<iframe src="example.php?app_link=YourApp://blabla" style="display:none;" scrolling="no" frameborder="0"></iframe>
<iframe src="example.php?full_link=http://play.google.com/xyz" style="display:none;" scrolling="no" frameborder="0"></iframe>
<?php
}

One more thing, use
:retab
to convert existing tab to spaces
http://vim.wikia.com/wiki/Converting_tabs_to_spaces
It was Docker running in the background in my case. If you have Docker installed, you may wanna close it and try again.
Import:
You must write columns in INSERT
statement
INSERT INTO TABLE
SELECT * FROM
Is not correct.
Insert into Table(Field1,...)
Select (Field1,...) from TABLE
Is correct
you may be create function before so, update your function again using.
Alter FUNCTION dbo.Afisho_rankimin(@emri_rest int)
RETURNS int
AS
BEGIN
Declare @rankimi int
Select @rankimi=dbo.RESTORANTET.Rankimi
From RESTORANTET
Where dbo.RESTORANTET.ID_Rest=@emri_rest
RETURN @rankimi
END
GO
SELECT dbo.Afisho_rankimin(5) AS Rankimi
GO
As already stated: closures, out of the box, cannot be serialized.
However, using the __sleep()
, __wakeup()
magic methods and reflection u CAN manually make closures serializable. For more details see extending-php-5-3-closures-with-serialization-and-reflection
This makes use of reflection and the php function eval. Do note this opens up the possibility of CODE injection, so please take notice of WHAT you are serializing.
You can do something like this, where you set a negative margin
on the h1
(or whatever header you are using)
div{
height:100px;
width:100px;
border:2px solid black;
}
h1{
width:30px;
margin-top:-10px;
margin-left:5px;
background:white;
}
Note: you need to set a background
as well as a width
on the h1
Example: http://jsfiddle.net/ZgEMM/
EDIT
To make it work with hiding the div
, you could use some jQuery like this
$('a').click(function(){
var a = $('h1').detach();
$('div').hide();
$(a).prependTo('body');
});
(You will need to modify...)
Example #2: http://jsfiddle.net/ZgEMM/4/
using bootstrap you can add <div class="col-sm-1 col-xs-1 col-md-1 col-lg-1"></div>
between buttons.
Note that if you are using a Portable Class Library, HttpClient will not have PostAsJsonAsync method. To post a content as JSON using a Portable Class Library, you will have to do this:
HttpClient client = new HttpClient();
HttpContent contentPost = new StringContent(argsAsJson, Encoding.UTF8,
"application/json");
await client.PostAsync(new Uri(wsUrl), contentPost).ContinueWith(
(postTask) => postTask.Result.EnsureSuccessStatusCode());
Aside from the (excellent) suggestion to use TikZ, you could use gastex. I used this before TikZ was available and it did its job too.
I know that this isn't what you asked for but LINQPad is a really great tool to teach yourself LINQ (and it's free :o).
When time isn't critical, I have been using it for the last week or so instead or a query window in SQL Server and my LINQ skills are getting better and better.
It's also a nice little code snippet tool. Its only downside is that the free version doesn't have IntelliSense.
While most people will tell you to just use multiple repositories, I feel it's worth mentioning there are other solutions.
A single repository can contain multiple independent branches, called orphan branches. Orphan branches are completely separate from each other; they do not share histories.
git checkout --orphan BRANCHNAME
This creates a new branch, unrelated to your current branch. Each project should be in its own orphaned branch.
Now for whatever reason, git needs a bit of cleanup after an orphan checkout.
rm .git/index
rm -r *
Make sure everything is committed before deleting
Once the orphan branch is clean, you can use it normally.
Avoid all the hassle of orphan branches. Create two independent repositories, and push them to the same remote. Just use different branch names for each repo.
# repo 1
git push origin master:master-1
# repo 2
git push origin master:master-2
This works in Python:
import base64
def IsBase64(str):
try:
base64.b64decode(str)
return True
except Exception as e:
return False
if IsBase64("ABC"):
print("ABC is Base64-encoded and its result after decoding is: " + str(base64.b64decode("ABC")).replace("b'", "").replace("'", ""))
else:
print("ABC is NOT Base64-encoded.")
if IsBase64("QUJD"):
print("QUJD is Base64-encoded and its result after decoding is: " + str(base64.b64decode("QUJD")).replace("b'", "").replace("'", ""))
else:
print("QUJD is NOT Base64-encoded.")
Summary: IsBase64("string here")
returns true if string here
is Base64-encoded, and it returns false if string here
was NOT Base64-encoded.
Please check whether this helps:
select TOP 1
product,
price
from
table1
where
(project=1 OR Customer=2 OR company=3) AND
price IS NOT NULL
ORDER BY company
You may also write it in two statements if it mostly is true use:
a = 5
a = 10 if false
Or use a switch statement if you need more possibilities:
a = switch x
when true then 5
when false then 10
With a boolean it may be oversized but i find it very readable.
This also works:
if printf -- '%s' "$haystack" | egrep -q -- "$needle"
then
printf "Found needle in haystack"
fi
And the negative test is:
if ! printf -- '%s' "$haystack" | egrep -q -- "$needle"
then
echo "Did not find needle in haystack"
fi
I suppose this style is a bit more classic -- less dependent upon features of Bash shell.
The --
argument is pure POSIX paranoia, used to protected against input strings similar to options, such as --abc
or -a
.
Note: In a tight loop this code will be much slower than using internal Bash shell features, as one (or two) separate processes will be created and connected via pipes.
Double check your text with the Hex Editor Plug-in. In your case there may have been some control characters which have crept into your text. Usually you'll look at the white-space, and it will say 32 32 32 32, or for Unicode 32 00 32 00 32 00 32 00. You may find the problem this way, providing there isn't masses of code.
Download the Hex Plugin from here; http://sourceforge.net/projects/npp-plugins/files/Hex%20Editor/
This will add a path to your Python process / instance (i.e. the running executable). The path will not be modified for any other Python processes. Another running Python program will not have its path modified, and if you exit your program and run again the path will not include what you added before. What are you are doing is generally correct.
set.py:
import sys
sys.path.append("/tmp/TEST")
loop.py
import sys
import time
while True:
print sys.path
time.sleep(1)
run: python loop.py &
This will run loop.py, connected to your STDOUT, and it will continue to run in the background. You can then run python set.py
. Each has a different set of environment variables. Observe that the output from loop.py
does not change because set.py
does not change loop.py
's environment.
A note on importing
Python imports are dynamic, like the rest of the language. There is no static linking going on. The import is an executable line, just like sys.path.append...

Try wrapping each button in it's own form in your view.
@using (Html.BeginForm("Action1", "Controller"))
{
<input type="submit" value="Button 1" />
}
@using (Html.BeginForm("Action2", "Controller"))
{
<input type="submit" value="Button 2" />
}
Form
isn't included in laravel
5.0 as it was on 4.0, steps to include it:
Begin by installing laravelcollective/html
package through Composer
. Edit your project's composer.json
file to require:
"require": {
"laravelcollective/html": "~5.0"
}
Next, update composer
from the Terminal:
composer update
Next, add your new provider to the providers
array of config/app.php
:
'providers' => [
// ...
'Collective\Html\HtmlServiceProvider',
// ...
],
Finally, add two class aliases to the aliases
array of config/app.php
:
'aliases' => [
// ...
'Form' => 'Collective\Html\FormFacade',
'Html' => 'Collective\Html\HtmlFacade',
// ...
],
At this point, Form
should be working
Update Laravel 5.8
(2019-04-05):
In Laravel 5.8
, the providers
in the config/app.php
can be declared as:
Collective\Html\HtmlServiceProvider::class,
instead of:
'Collective\Html\HtmlServiceProvider',
This notation is the same for the aliases.
The first one matches a single whitespace, whereas the second one matches one or many whitespaces. They're the so-called regular expression quantifiers, and they perform matches like this (taken from the documentation):
Greedy quantifiers
X? X, once or not at all
X* X, zero or more times
X+ X, one or more times
X{n} X, exactly n times
X{n,} X, at least n times
X{n,m} X, at least n but not more than m times
Reluctant quantifiers
X?? X, once or not at all
X*? X, zero or more times
X+? X, one or more times
X{n}? X, exactly n times
X{n,}? X, at least n times
X{n,m}? X, at least n but not more than m times
Possessive quantifiers
X?+ X, once or not at all
X*+ X, zero or more times
X++ X, one or more times
X{n}+ X, exactly n times
X{n,}+ X, at least n times
X{n,m}+ X, at least n but not more than m times
Another possible problem is that the debugger port may be blocked by the firewall. For example, I was using mule anypoint studio (v 5.4.3). The default debugger port is 6666. When a flow is executed, it would not stop at breakpoint. when I changed the port to another (e.g. 8099), it worked fine.
Assuming you cannot modify DDL (to create a unique constraint) or are limited to only being able to write DML then check for a null on filtered result of your values against the whole table
insert into funds (ID, date, price)
select
T.*
from
(select 23 ID, '2013-02-12' date, 22.43 price) T
left join
funds on funds.ID = T.ID and funds.date = T.date
where
funds.ID is null
I encountered the same issue, when jdk 1.7 was used to compile then jre 1.4 was used for execution.
My solution was to set environment variable PATH by adding pathname C:\glassfish3\jdk7\bin in front of the existing PATH setting. The updated value is "C:\glassfish3\jdk7\bin;C:\Sun\SDK\bin". After the update, the problem was gone.
So actually, my comment that you should do a console.log(el.nativeElement)
should have pointed you in the right direction, but I didn't expect the output to be just a string representing the DOM Element
.
What you have to do to inspect it in the way it helps you with your problem, is to do a console.log(el)
in your example, then you'll have access to the nativeElement
object and will see a property called innerHTML
.
Which will lead to the answer to your original question:
let myCurrentContent:string = el.nativeElement.innerHTML; // get the content of your element
el.nativeElement.innerHTML = 'my new content'; // set content of your element
Since it's the accepted answer and web workers are getting more important day to day (and it's considered best practice anyway) I want to add this suggestion by Mark Rajcok here.
The best way to manipulate DOM Elements
programmatically is using the Renderer:
constructor(private _elemRef: ElementRef, private _renderer: Renderer) {
this._renderer.setElementProperty(this._elemRef.nativeElement, 'innerHTML', 'my new content');
}
Since Renderer
is deprecated now, use Renderer2 instead with setProperty
This question with its answer explained the console.log
behavior.
Which means that console.dir(el.nativeElement)
would be the more direct way of accessing the DOM Element
as an "inspectable" Object in your console for this situation.
Hope this helped.
You can pass arbitrary objects to the template with the flash parameter.
redirect_to :back, flash: {new_solution_errors: solution.errors}
And then access them in the template via the hash.
<% flash[:new_solution_errors].each do |err| %>
I had the same problem, and even with the solutions provided here it did not work. The checkboxes would simply not change, their Value would remain null. It took me ages to realize my dumbness:
Turns out, I called the form1.PopulateDataGridView(my data)
on the Form derived class Form1 before I called form1.Show()
. When I changed up the order, that is to call Show()
first, and then read the data and fill in the checkboxes, the value did not stay null.
Try this
static DataTable ConvertToDatatable(List<Item> list)
{
DataTable dt = new DataTable();
dt.Columns.Add("Name");
dt.Columns.Add("Price");
dt.Columns.Add("URL");
foreach (var item in list)
{
var row = dt.NewRow();
row["Name"] = item.Name;
row["Price"] = Convert.ToString(item.Price);
row["URL"] = item.URL;
dt.Rows.Add(row);
}
return dt;
}
display: none
doesn’t have a literal opposite like visibility:hidden
does.
The visibility
property decides whether an element is visible or not. It therefore has two states (visible
and hidden
), which are opposite to each other.
The display
property, however, decides what layout rules an element will follow. There are several different kinds of rules for how elements will lay themselves out in CSS, so there are several different values (block
, inline
, inline-block
etc — see the documentation for these values here ).
display:none
removes an element from the page layout entirely, as if it wasn’t there.
All other values for display
cause the element to be a part of the page, so in a sense they’re all opposite to display:none
.
But there isn’t one value that’s the direct converse of display:none
- just like there's no one hair style that's the opposite of "bald".
I faced the same problem when I tried to install Angular.js with bower in my project. I seems bower has lots of javascript files it downloaded automatically which caused my IDE to stuck in validation process for a long time. So, I solved this problem this way,
My IDE currently working without freezing. I took help from there. Tern I guess it can be helpful, where any IDE stuck due to lots of Javascript file.
I'm learning AngularJS and was struggling with selection as well. I know this question is already answered, but I wanted to share some more code nevertheless.
In my test I have two listboxes: car makes and car models. The models list is disabled until some make is selected. If selection in makes listbox is later reset (set to 'Select Make') then the models listbox becomes disabled again AND its selection is reset as well (to 'Select Model'). Makes are retrieved as a resource while models are just hard-coded.
[
{"code": "0", "name": "Select Make"},
{"code": "1", "name": "Acura"},
{"code": "2", "name": "Audi"}
]
angular.module('makeServices', ['ngResource']).
factory('Make', function($resource){
return $resource('makes.json', {}, {
query: {method:'GET', isArray:true}
});
});
<div ng:controller="MakeModelCtrl">
<div>Make</div>
<select id="makeListBox"
ng-model="make.selected"
ng-options="make.code as make.name for make in makes"
ng-change="makeChanged(make.selected)">
</select>
<div>Model</div>
<select id="modelListBox"
ng-disabled="makeNotSelected"
ng-model="model.selected"
ng-options="model.code as model.name for model in models">
</select>
</div>
function MakeModelCtrl($scope)
{
$scope.makeNotSelected = true;
$scope.make = {selected: "0"};
$scope.makes = Make.query({}, function (makes) {
$scope.make = {selected: makes[0].code};
});
$scope.makeChanged = function(selectedMakeCode) {
$scope.makeNotSelected = !selectedMakeCode;
if ($scope.makeNotSelected)
{
$scope.model = {selected: "0"};
}
};
$scope.models = [
{code:"0", name:"Select Model"},
{code:"1", name:"Model1"},
{code:"2", name:"Model2"}
];
$scope.model = {selected: "0"};
}
None of the methods worked for me. But I have found this Real time matplotlib plot is not working while still in a loop
All you need is to add
plt.pause(0.0001)
and then you could see the new plots.
So your code should look like this, and it will work
import matplotlib.pyplot as plt
import numpy as np
plt.ion() ## Note this correction
fig=plt.figure()
plt.axis([0,1000,0,1])
i=0
x=list()
y=list()
while i <1000:
temp_y=np.random.random();
x.append(i);
y.append(temp_y);
plt.scatter(i,temp_y);
i+=1;
plt.show()
plt.pause(0.0001) #Note this correction
Joel is it that @SearchLetter hasn't been declared yet? Also the length of @SearchLetter2 isn't long enough for 't%'. Try a varchar of a longer length.
Try:
float x = (float)rand()/(float)(RAND_MAX/a);
To understand how this works consider the following.
N = a random value in [0..RAND_MAX] inclusively.
The above equation (removing the casts for clarity) becomes:
N/(RAND_MAX/a)
But division by a fraction is the equivalent to multiplying by said fraction's reciprocal, so this is equivalent to:
N * (a/RAND_MAX)
which can be rewritten as:
a * (N/RAND_MAX)
Considering N/RAND_MAX
is always a floating point value between 0.0 and 1.0, this will generate a value between 0.0 and a
.
Alternatively, you can use the following, which effectively does the breakdown I showed above. I actually prefer this simply because it is clearer what is actually going on (to me, anyway):
float x = ((float)rand()/(float)(RAND_MAX)) * a;
Note: the floating point representation of a
must be exact or this will never hit your absolute edge case of a
(it will get close). See this article for the gritty details about why.
Sample
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main(int argc, char *argv[])
{
srand((unsigned int)time(NULL));
float a = 5.0;
for (int i=0;i<20;i++)
printf("%f\n", ((float)rand()/(float)(RAND_MAX)) * a);
return 0;
}

another way it to use the millisecond timer:

In 5.0 Lollipop, Google added an official method, WebChromeClient.onShowFileChooser. They even provide a way to automatically generate the file chooser intent so that it uses the input accept mime types.
public class MyWebChromeClient extends WebChromeClient {
// reference to activity instance. May be unnecessary if your web chrome client is member class.
private MyActivity activity;
public boolean onShowFileChooser(WebView webView, ValueCallback<Uri[]> filePathCallback, FileChooserParams fileChooserParams) {
// make sure there is no existing message
if (myActivity.uploadMessage != null) {
myActivity.uploadMessage.onReceiveValue(null);
myActivity.uploadMessage = null;
}
myActivity.uploadMessage = filePathCallback;
Intent intent = fileChooserParams.createIntent();
try {
myActivity.startActivityForResult(intent, MyActivity.REQUEST_SELECT_FILE);
} catch (ActivityNotFoundException e) {
myActivity.uploadMessage = null;
Toast.makeText(myActivity, "Cannot open file chooser", Toast.LENGTH_LONG).show();
return false;
}
return true;
}
}
public class MyActivity extends ... {
public static final int REQUEST_SELECT_FILE = 100;
public ValueCallback<Uri[]> uploadMessage;
protected void onActivityResult(int requestCode, int resultCode, Intent data){
if (requestCode == REQUEST_SELECT_FILE) {
if (uploadMessage == null) return;
uploadMessage.onReceiveValue(WebChromeClient.FileChooserParams.parseResult(resultCode, data));

For Android versions before KitKat, the private methods mentioned in the other answers work. I have not found a good workaround for KitKat (4.4).
I found out a solution about excluding SecurityAutoConfiguration class.
Example:
@SpringBootApplication(exclude = {SecurityAutoConfiguration.class })
public class ReportApplication {
public static void main(String[] args) throws Exception {
SpringApplication.run(MyApplication.class, args);
}
}
UITableViewController
does the Scrolling automatically, indeed.
The difference compared to using a UIViewController
is, that you have to create Navbar-Buttonitems programmatically by using the NavigationController
, when using a TableViewController
.
If you write a function then once you leave it all names inside disappear.
The concept is called namespace and it's so good, it made it into the Zen of Python:
Namespaces are one honking great idea -- let's do more of those!
The namespace of IPython can likewise be reset with the magic command %reset -f
. (The -f
means "force"; in other words, "don't ask me if I really want to delete all the variables, just do it.")
If the above solutions don't work and you saw the below error:
npm ERR! The operation was rejected by your operating system.
npm ERR! It is likely you do not have the permissions to access this file as the current user
try with sudo npm install
you can pass the json object as the body(third argument) of the fetch request.
If you use angular-cli you can do :
Install the dependency :
npm install jquery --save
npm install @types/jquery --save-dev
Import the file :
Add "../node_modules/jquery/dist/jquery.min.js" to the "script" section in .angular-cli.json file
Declare jquery :
Add "$" to the "types" section of tsconfig.app.json
You can find more details on official angular cli doc
If you care about getting coordinates based on an ellipsoid rather than a sphere, take a look at Geographic_coordinate_conversion - it gives the formulae. GEodetic Datum has the WGS84 constants you need for the conversion.
The formulae there also take into account the altitude relative to the reference ellipsoid surface (useful if you are getting altitude data from a GPS device).
Well, I'd say use the DIV instead of table as it would be much easier (but there's nothing wrong with using tables).
My approach would be to use jQuery.ajax and request more data from server and that way, the selected DIV (or TD if you use table) will automatically expand based on requested content.
That way, it saves bandwidth and makes it go faster as you don't load all content at once. It loads only when it's selected.
The code you posted does not produce the error messages you quoted. You should provide a (small) example that actually exhibits the problem.
Scanner
is used for parsing tokens from the contents of the stream while BufferedReader
just reads the stream and does not do any special parsing.
In fact you can pass a BufferedReader
to a scanner
as the source of characters to parse.
Try something like this:
foreach (ListItem listItem in YrChkBox.Items)
{
if (listItem.Selected)
{
//do some work
}
else
{
//do something else
}
}
This looks like a problem with line endings in your code. If you're going to be using all these other scientific packages, you may as well use Pandas for the CSV reading part, which is both more robust and more useful than just the csv
module:
import pandas
colnames = ['year', 'name', 'city', 'latitude', 'longitude']
data = pandas.read_csv('test.csv', names=colnames)
If you want your lists as in the question, you can now do:
names = data.name.tolist()
latitude = data.latitude.tolist()
longitude = data.longitude.tolist()
I am trying to avoid using VBA. But if has to be, then it has to be:)
There is quite simple UDF for you:
Function myCountIf(rng As Range, criteria) As Long
Dim ws As Worksheet
For Each ws In ThisWorkbook.Worksheets
myCountIf = myCountIf + WorksheetFunction.CountIf(ws.Range(rng.Address), criteria)
Next ws
End Function
and call it like this: =myCountIf(I:I,A13)
P.S. if you'd like to exclude some sheets, you can add If
statement:
Function myCountIf(rng As Range, criteria) As Long
Dim ws As Worksheet
For Each ws In ThisWorkbook.Worksheets
If ws.name <> "Sheet1" And ws.name <> "Sheet2" Then
myCountIf = myCountIf + WorksheetFunction.CountIf(ws.Range(rng.Address), criteria)
End If
Next ws
End Function
UPD:
I have four "reference" sheets that I need to exclude from being scanned/searched. They are currently the last four in the workbook
Function myCountIf(rng As Range, criteria) As Long
Dim i As Integer
For i = 1 To ThisWorkbook.Worksheets.Count - 4
myCountIf = myCountIf + WorksheetFunction.CountIf(ThisWorkbook.Worksheets(i).Range(rng.Address), criteria)
Next i
End Function
Pretty late to the party, but I was struck here and got help from a friend. The thing was not to use PowerMock. This works with the latest version of Mockito.
Mockito comes with this org.mockito.internal.util.reflection.FieldSetter
.
What it basically does is helps you modify private fields using reflection.
This is how you use it:
@Mock
private Person mockedPerson;
private Test underTest;
// ...
@Test
public void testMethod() {
FieldSetter.setField(underTest, underTest.getClass().getDeclaredField("person"), mockedPerson);
// ...
verify(mockedPerson).someMethod();
}
This way you can pass a mock object and then verify it later.
Here is the reference.
An old question, but I'll answer anyway. The answer to the actual question asked is that the bare return is redundant and should be left out.
Furthermore, the suggested value is false for the following reason:
if (ret<0) return;
Redefining a C reserved word as a macro is a bad idea on the face of it, but this particular suggestion is simply unsupportable, both as an argument and as code.
I required the same functionality as requested in the main question. As I was not allowed to use any 3rd party libraries, I have created my own solution basing on @Archimedes Trajano solution.
Following is my solution.

It compares two XML strings and takes care of any mismatching namespace mappings by translating them to unique values in both input strings.
Can be fine tuned i.e. in case of translation of namespaces. But for my requirements just does the job.
import pickle
your_data = {'foo': 'bar'}
# Store data (serialize)
with open('filename.pickle', 'wb') as handle:
pickle.dump(your_data, handle, protocol=pickle.HIGHEST_PROTOCOL)
# Load data (deserialize)
with open('filename.pickle', 'rb') as handle:

The advantage of HIGHEST_PROTOCOL
is that files get smaller. This makes unpickling sometimes much faster.

Yeah, you can do it. Just open Settings -> Live Templates. Create new one with syso

This does not answer the original question, but as the question is highly ranked and linked for any ContextClassLoader
query, I think it is important to answer the related question of when the context class loader should be used. Short answer: never use the context class loader! But set it to getClass().getClassLoader()
when you have to call a method that is missing a ClassLoader
parameter.
When code from one class asks to load another class, the correct class loader to use is the same class loader as the caller class (i.e., getClass().getClassLoader()
). This is the way things work 99.9% of the time because this is what the JVM does itself the first time you construct an instance of a new class, invoke a static method, or access a static field.
When you want to create a class using reflection (such as when deserializing or loading a configurable named class), the library that does the reflection should always ask the application which class loader to use, by receiving the ClassLoader
as a parameter from the application. The application (which knows all the classes that need constructing) should pass it getClass().getClassLoader()
.
Any other way to obtain a class loader is incorrect. If a library uses hacks such as Thread.getContextClassLoader()
, sun.misc.VM.latestUserDefinedLoader()
, or sun.reflect.Reflection.getCallerClass()
it is a bug caused by a deficiency in the API. Basically, Thread.getContextClassLoader()
exists only because whoever designed the ObjectInputStream
API forgot to accept the ClassLoader
as a parameter, and this mistake has haunted the Java community to this day.
That said, many many JDK classes use one of a few hacks to guess some class loader to use. Some use the ContextClassLoader
(which fails when you run different apps on a shared thread pool, or when you leave the ContextClassLoader null
), some walk the stack (which fails when the direct caller of the class is itself a library), some use the system class loader (which is fine, as long as it is documented to only use classes in the CLASSPATH
) or bootstrap class loader, and some use an unpredictable combination of the above techniques (which only makes things more confusing). This has resulted in much weeping and gnashing of teeth.
When using such an API, first, try to find an overload of the method that accepts the class loader as a parameter. If there is no sensible method, then try setting the ContextClassLoader
before the API call (and resetting it afterwards):
ClassLoader originalClassLoader = Thread.currentThread().getContextClassLoader();
try {
Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
// call some API that uses reflection without taking ClassLoader param
} finally {
Thread.currentThread().setContextClassLoader(originalClassLoader);
}

Make sure when executing Michael Krelin's solution you do the following
cat <your_public_key_file> >> ~/.ssh/authorized_keys
Note the double >

the existing contents of authorized_keys will be over-written (nuked!) and that may not be desirable
A small change to your algorithm:
filne = "D:/testtube/testdkanimfilternode.txt"
f = open(filne, 'r+')
while 1:
lines = f.readlines()
if not lines:
break
line_iter= iter(lines) # here
for line in line_iter: # and here
print line
if (line[:5] == "anim "):
print 'next() '
ne = line_iter.next() # and here
print ' ne ',ne,'\n'
break
f.close()
However, using the pairwise
function from itertools
recipes:
def pairwise(iterable):
"s -> (s0,s1), (s1,s2), (s2, s3), ..."
a, b = itertools.tee(iterable)
next(b, None)
return itertools.izip(a, b)
you can change your loop into:
for line, next_line in pairwise(f): # iterate over the file directly
print line
if line.startswith("anim "):
print 'next() '
print ' ne ', next_line, '\n'
break

As I needed to use this feature for my latest project (at one point we updated from 1.10.19), just to keep the users (that are already using the mockito-core version 2.1.0 or greater) up to date, the static methods from the above answers should be taken from ArgumentMatchers
class:
import static org.mockito.ArgumentMatchers.isA;
import static org.mockito.ArgumentMatchers.any;
Please keep this in mind if you are planning to keep your Mockito artefacts up to date as possibly starting from version 3, this class may no longer exist:
As per 2.1.0 and above, Javadoc of org.mockito.Matchers states:
Use
org.mockito.ArgumentMatchers
. This class is now deprecated in order to avoid a name clash with Hamcrest *org.hamcrest.Matchers
class. This class will likely be removed in version 3.0.
I have written a little article on mockito wildcards if you're up for further reading.
I use a small set of documentation patterns:
It's an iterator returned by the filter function.
If you want a list, just do
list(filter(f, range(2, 25)))
Nonetheless, you can just iterate over this object with a for
loop.
for e in filter(f, range(2, 25)):
do_stuff(e)
In PostgresQL it is:
ALTER TABLE tableName ALTER COLUMN columnName DROP NOT NULL;
in your <head>
<meta id="viewport"
name="viewport"
content="width=1024, height=768, initial-scale=0, minimum-scale=0.25" />
somewhere in your javascript
document.getElementById("viewport").setAttribute("content",
"initial-scale=0.5; maximum-scale=1.0; user-scalable=0;");
... but good luck with tweaking it for your device, fiddling for hours... and i'm still not there!
You can get visitors country and city using ipstack geo API.You need to get your own ipstack API and then use the code below:
<?php
$ip = $_SERVER['REMOTE_ADDR'];
$api_key = "YOUR_API_KEY";
$freegeoipjson = file_get_contents("http://api.ipstack.com/".$ip."?access_key=".$api_key."");
$jsondata = json_decode($freegeoipjson);
$countryfromip = $jsondata->country_name;
echo "Country: ". $countryfromip ."";
?>

something like below
var idList=new int[]{1, 2, 3, 4};
using (var db=new SomeDatabaseContext())
{
var friends= db.Friends.Where(f=>idList.Contains(f.ID)).ToList();
friends.ForEach(a=>a.msgSentBy='1234');
db.SaveChanges();
}
you can update multiple fields as below
friends.ForEach(a =>
{
a.property1 = value1;
a.property2 = value2;
});
If there is a suitable index, in this case on the publish_date
field, then MySQL need not scan the whole index to get the 20 records requested - the 20 records will be found at the start of the index. But if there is no suitable index, then a full scan of the table will be needed.
There is a MySQL Performance Blog article from 2009 on this.
I've investigated A LOT on how to properly manage 404s in MVC (specifically MVC3), and this, IMHO is the best solution I've come up with:
In global.asax:
public class MvcApplication : HttpApplication
{
protected void Application_EndRequest()
{
if (Context.Response.StatusCode == 404)
{
Response.Clear();
var rd = new RouteData();
rd.DataTokens["area"] = "AreaName"; // In case controller is in another area
rd.Values["controller"] = "Errors";
rd.Values["action"] = "NotFound";
IController c = new ErrorsController();
c.Execute(new RequestContext(new HttpContextWrapper(Context), rd));
}
}
}
ErrorsController:
public sealed class ErrorsController : Controller
{
public ActionResult NotFound()
{
ActionResult result;
object model = Request.Url.PathAndQuery;
if (!Request.IsAjaxRequest())
result = View(model);
else
result = PartialView("_NotFound", model);
return result;
}
}
(Optional)
Explanation:
AFAIK, there are 6 different cases that an ASP.NET MVC3 apps can generate 404s.
(Automatically generated by ASP.NET Framework:)
(1) An URL does not find a match in the route table.
(Automatically generated by ASP.NET MVC Framework:)
(2) An URL finds a match in the route table, but specifies a non-existent controller.
(3) An URL finds a match in the route table, but specifies a non-existant action.
(Manually generated:)
(4) An action returns an HttpNotFoundResult by using the method HttpNotFound().
(5) An action throws an HttpException with the status code 404.
(6) An actions manually modifies the Response.StatusCode property to 404.
Normally, you want to accomplish 3 objectives:
(1) Show a custom 404 error page to the user.
(2) Maintain the 404 status code on the client response (specially important for SEO).
(3) Send the response directly, without involving a 302 redirection.
There are various ways to try to accomplish this:
(1)
<system.web>
<customErrors mode="On">
<error statusCode="404" redirect="~/Errors/NotFound"/>
</customError>
</system.web>
Problems with this solution:
(2)
<system.webServer>
<httpErrors errorMode="Custom">
<remove statusCode="404"/>
<error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
</httpErrors>
</system.webServer>
Problems with this solution:
(3)
<system.webServer>
<httpErrors errorMode="Custom" existingResponse="Replace">
<remove statusCode="404"/>
<error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
</httpErrors>
</system.webServer>
Problems with this solution:
(4)
<system.web>
<customErrors mode="On">
<error statusCode="404" redirect="~/Errors/NotFound"/>
</customError>
</system.web>
and
<system.webServer>
<httpErrors errorMode="Custom">
<remove statusCode="404"/>
<error statusCode="404" path="App/Errors/NotFound" responseMode="ExecuteURL"/>
</httpErrors>
</system.webServer>
Problems with this solution:
People that have troubled with this before even tried to create their own libraries (see http://aboutcode.net/2011/02/26/handling-not-found-with-asp-net-mvc3.html). But the previous solution seems to cover all the cases without the complexity of using an external library.
If you are a Mac user and have keychain enabled, you to need to remove the authorization information that is stored in the keychain:
- Open up Keychain access
- Click "All items" under category in the left-hand column
- Search for git
- Delete all git entries.
Then you should change your username and email from the terminal using git config
:
$ git config --global user.name "Bob"
$ git config --global user.email "[email protected]"
Now if you try to push to the repository you will be asked for a username and password. Enter the login credentials you are trying to switch to. This problem normally pops up if you signed into GitHub on a browser using a different username and password or previously switched accounts on your terminal.
Sometimes it should be solved by displaying as table/table-cell. For example, a fast title screen. It is a recommended way by W3 also. I recommend you check this link called Centering a block or image from W3C.org.
The tips used here are:
.container {_x000D_
position: absolute;_x000D_
display: table;_x000D_
width: 100%;_x000D_
height: 100%;_x000D_
}_x000D_
.content {_x000D_
display: table-cell;_x000D_
vertical-align: middle;_x000D_
}
_x000D_
<div class="container">_x000D_
<div class="content">_x000D_
<h1 style="text-align:center">Peace in the world</h1>_x000D_
</div>_x000D_
</div>
_x000D_
Personally I actually disagree about use helpers for this purpose.
For .NET 4.0 and higher, you can compare elements in array or tuples using the StructuralComparisons type:
object[] a1 = { "string", 123, true };
object[] a2 = { "string", 123, true };
Console.WriteLine (a1 == a2); // False (because arrays is reference types)
Console.WriteLine (a1.Equals (a2)); // False (because arrays is reference types)
IStructuralEquatable se1 = a1;
//Next returns True
Console.WriteLine (se1.Equals (a2, StructuralComparisons.StructuralEqualityComparer));
IMO this link from Yochai Timmer was very good and relevant but painful to read. I wrote a summary.
Yochai, if you ever read this, please see the note at the end.
For the original post read : warning LNK4098: defaultlib "LIBCD" conflicts with use of other libs
LINK : warning LNK4098: defaultlib "LIBCD" conflicts with use of other libs; use /NODEFAULTLIB:library
one part of the system was compiled to use a single threaded standard (libc) library with debug information (libcd) which is statically linked
while another part of the system was compiled to use a multi-threaded standard library without debug information which resides in a DLL and uses dynamic linking
Ignore the warning, after all it is only a warning. However, your program now contains multiple instances of the same functions.
Use the linker option /NODEFAULTLIB:lib. This is not a complete solution, even if you can get your program to link this way you are ignoring a warning sign: the code has been compiled for different environments, some of your code may be compiled for a single threaded model while other code is multi-threaded.
[...] trawl through all your libraries and ensure they have the correct link settings
In the latter, as it in mentioned in the original post, two common problems can arise :
You have a third party library which is linked differently to your application.
You have other directives embedded in your code: normally this is the MFC. If any modules in your system link against MFC all your modules must nominally link against the same version of MFC.
For those cases, ensure you understand the problem and decide among the solutions.
Note : I wanted to include that summary of Yochai Timmer's link into his own answer but since some people have trouble to review edits properly I had to write it in a separate answer. Sorry

You can do something like that in ES6.
new Array(10).fill().map((e,i) => {
return {idx: i}
});
os.rename(old, new)
This is found in the Python docs: http://docs.python.org/library/os.html
They represent [
and ]
. The encoding is called "URL encoding".
Similarly to the approved answer. If you want to create an array from dictionary keys:
np.array( tuple(dict.keys()) )
If you want to create an array from dictionary values:
np.array( tuple(dict.values()) )
I had this same problem getting PowerPoint to close after newing up the Application object in my VSTO AddIn. I tried all the answers here with limited success.
This is the solution I found for my case - DONT use 'new Application', the AddInBase base class of ThisAddIn already has a handle to 'Application'. If you use that handle where you need it (make it static if you have to) then you don't need to worry about cleaning it up and PowerPoint won't hang on close.
Sample program to mouse hover using Selenium java WebDriver :
public class Mhover {
public static void main(String[] args){
WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.get("http://www.google.com");
WebElement ele = driver.findElement(By.id("gbqfba"));
Actions action = new Actions(driver);
action.moveToElement(ele).build().perform();
}
}
You can do something like height: calc(100% - nPx); for example height: calc(100% - 70px);
Others have taken the approach to say "don't do this" but that doesn't really answer the poster's question. Let's just assume that everyone knows this is a bad idea, but we are curious about how it's done anyway...
You cannot disable the back button on a user's browser, but you can make it so that your application breaks (displays an error message, requiring the user to start over) if the user goes back.
One approach I have seen for doing this is to pass a token on every URL within the application, and within every form. The token is regenerated on every page, and once the user loads a new page any tokens from previous pages are invalidated.
When the user loads a page, the page will only show if the correct token (which was given to all links/forms on the previous page) was passed to it.
The online banking application my bank provides is like this. If you use the back button at all, no more links will work and no more page reloads can be made - instead you see a notice telling you that you cannot go back, and you have to start over.
Tried everything. I deleted m2e and installed m2e version 2.7.0. Then deleted the .m2 directory and force updated maven. It worked!
Vim have 2 modes

Per Truth value testing, 'None' directly tests as FALSE, so the simplest expression will suffice:

The best way to extract the values is to just do the following
json.loads(dataframe[column].value_counts().to_json())
This returns a dictionary which you can use like any other dict. Using values or keys.
{"apple": 5, "sausage": 2, "banana": 2, "cheese": 1}
If you have no FIRST/FIRST conflicts and no FIRST/FOLLOW conflicts, your grammar is LL(1).
An example of a FIRST/FIRST conflict:
S -> Xb | Yc
X -> a
Y -> a
By seeing only the first input symbol a, you cannot know whether to apply the production S -> Xb or S -> Yc, because a is in the FIRST set of both X and Y.
An example of a FIRST/FOLLOW conflict:
S -> AB
A -> fe | epsilon
B -> fg
By seeing only the first input symbol f, you cannot decide whether to apply the production A -> fe or A -> epsilon, because f is in both the FIRST set of A and the FOLLOW set of A (A can be parsed as epsilon and B as f).
Notice that if you have no epsilon-productions you cannot have a FIRST/FOLLOW conflict.
Arve Waltin's solution looks good, although I haven't tested it yet. There is another solution in case you have trouble getting that to work.... Extend AlertDialog.Builder
and override all the methods (eg. setText
, setTitle
, setView
, etc) to not set the actual Dialog's text/title/view, but to create a new view within the Dialog's View do everything in there. Then you are free to style everything as you please.
To clarify, as far as the parent class is concerned, the View is set, and nothing else.
As far as your custom extended class is concerned, everything is done within that view.
The best way in browsers that support it, is to send the file as a Blob, or using FormData if you want a multipart form. You do not need a FileReader for that. This is both simpler and more efficient than trying to read the data.
If you specifically want to send it as multipart/form-data
, you can use a FormData object:
var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open("POST", '/pushfile', true);
var formData = new FormData();
// This should automatically set the file name and type.
formData.append("file", file);
// Sending FormData automatically sets the Content-Type header to multipart/form-data
xmlHttpRequest.send(formData);
You can also send the data directly, instead of using multipart/form-data
. See the documentation. Of course, this will need a server-side change as well.
// file is an instance of File, e.g. from a file input.
var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open("POST", '/pushfile', true);
xmlHttpRequest.setRequestHeader("Content-Type", file.type);
// Send the binary data.
// Since a File is a Blob, we can send it directly.
xmlHttpRequest.send(file);
For browser support, see: http://caniuse.com/#feat=xhr2 (most browsers, including IE 10+).
transferring file from local to remote host
scp -i (path of your key) (path for your file to be transferred) (username@ip):(path where file to be copied)
e.g scp -i aws.pem /home/user1/Desktop/testFile ec2-user@someipAddress:/home/ec2-user/
P.S. - ec2-user@someipAddress of this ip address should have access to the destination folder in my case /home/ec2-user/
Don't manually edit the .designer files in visual studio that usually leads to headaches. Instead either specify it in the properties section of your DataGridRow which should be contained within a DataGrid element. Or if you just want VS to do it for you find the double click event within the properties page->events (little lightning bolt icon) and double click the text area where you would enter a function name for that event.

Verify current version of python by:
$ python --version
then check python is symbolic link to which file.
$ ll /usr/bin/python
Output Ex:
lrwxrwxrwx 1 root root 9 Jun 16 2014 /usr/bin/python -> python2.7*
Check other available versions of python:
$ ls /usr/bin/python*
Output Ex:
/usr/bin/python /usr/bin/python2.7-config /usr/bin/python3.4 /usr/bin/python3.4m-config /usr/bin/python3.6m /usr/bin/python3m
/usr/bin/python2 /usr/bin/python2-config /usr/bin/python3.4-config /usr/bin/python3.6 /usr/bin/python3.6m-config /usr/bin/python3m-config
/usr/bin/python2.7 /usr/bin/python3 /usr/bin/python3.4m /usr/bin/python3.6-config /usr/bin/python3-config /usr/bin/python-config
If want to change current version of python to 3.6 version edit file ~/.bashrc:
vim ~/.bashrc
add below line in the end of file and save:
alias python=/usr/local/bin/python3.6
To install pip for python 3.6
$ sudo apt-get install python3.6 python3.6-dev
$ sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python3.6
$ sudo easy_install pip
On Success, check current version of pip:
$ pip3 -V
Output Ex:
pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.6)
The problem is with your line
x=np.array ([x0*n])
Here you define x as a single-item array of -200.0. You could do this:
x=np.array ([x0,]*n)
or this:
x=np.zeros((n,)) + x0
Note: your imports are quite confused. You import numpy modules three times in the header, and then later import pylab (that already contains all numpy modules). If you want to go easy, with one single
from pylab import *
line in the top you could use all the modules you need.
No, that's not really possible, as
The goal of the MD5 and its family of hashing functions is
Think that you can get the MD5 of any string, even very long. And the MD5 is only 16 bytes long (32 if you write it in hexa to store or distribute it more easily). If you could reverse them, you'd have a magical compacting scheme.
This being said, as there aren't so many short strings (passwords...) used in the world, you can test them from a dictionary (that's called "brute force attack") or even google for your MD5. If the word is common and wasn't salted, you have a reasonable chance to succeed...
There is indeed no 64 bit version of Jet - and no plans (apparently) to produce one.
You might be able to use the ACE 64 bit driver: http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=23734
However, you may be able to switch the project to 32bit in the Express version (I haven't tried and don't have 2008 installed in any flavour anymore)

@Boris's solution is VERY good but the view can sometimes be corrupted.
For the perfect alignment, use the below code
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(self, selector: #selector(ViewController.keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(ViewController.keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)}
Functions:
@objc func keyboardWillShow(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
if self.view.frame.origin.y == 0{
self.view.frame.origin.y -= keyboardSize.height
}
}}
And,
@objc func keyboardWillHide(notification: NSNotification) {
if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
if self.view.frame.origin.y != 0{
self.view.frame.origin.y = 0
}
} }
Escaping quotes in VB6 or VBScript strings is simple in theory although often frightening when viewed. You escape a double quote with another double quote.
An example:
"c:\program files\my app\app.exe"
If I want to escape the double quotes so I could pass this to the shell execute function listed by Joe or the VB6 Shell function I would write it:
escapedString = """c:\program files\my app\app.exe"""
How does this work? The first and last quotes wrap the string and let VB know this is a string. Then each quote that is displayed literally in the string has another double quote added in front of it to escape it.
It gets crazier when you are trying to pass a string with multiple quoted sections. Remember, every quote you want to pass has to be escaped.
If I want to pass these two quoted phrases as a single string separated by a space (which is not uncommon):
"c:\program files\my app\app.exe" "c:\documents and settings\steve"
I would enter this:
escapedQuoteHell = """c:\program files\my app\app.exe"" ""c:\documents and settings\steve"""
I've helped my sysadmins with some VBScripts that have had even more quotes.
It's not pretty, but that's how it works.
Use git log
to find the revision you want to rollback to, and take note of the commit hash. After that, you have 2 options:
If you plan to commit anything after that revision, I recommend you to checkout to a new branch: git checkout -b <new_branch_name> <hash>
If you don't plan to commit anything after that revision, you can simply checkout without a branch: git checkout <hash>
- NOTE: This will put your repository in a 'detached HEAD' state, which means its currently not attached to any branch - then you'll have some extra work to merge new commits to an actual branch.
Example:
$ git log

$ git checkout 4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7
Note: moving to '4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7'
which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
git checkout -b <new_branch_name>
HEAD is now at 4553c14... Missing constness.
That way you don't lose any informations, thus you can move to a newer revision when it becomes stable.
Use the keys CtrlK,C to comment out the line and CtrlK,U to uncomment the line.
As an administrator working on other people's profile and you need to get the Id of the profile you are working on, you can use a ViewBag to capture the Id e.g ViewBag.UserId = userId; while userId is the string Parameter of the method you are working on.

Indeed, you can leave it empty (W3 validator doesn't complain).
Taking the idea one step further: leave out the ="". The advantage of this is that the link isn't treated as an anchor to the current page.

I know this is an old question, but I also know that some people are just like me and are always looking for uptodate answers, since old answers can sometimes have deprecated information if not updated.
Its now January 2020, and I am using Django 2.2.6 and Python 3.7
Note: I use DJANGO REST FRAMEWORK, the code below for sending email was in a model viewset in my views.py
So after reading multiple nice answers, this is what I did.
from django.template.loader import render_to_string
from django.core.mail import EmailMultiAlternatives
def send_receipt_to_email(self, request):
emailSubject = "Subject"
emailOfSender = "[email protected]"
emailOfRecipient = '[email protected]'
context = ({"name": "Gilbert"}) #Note I used a normal tuple instead of Context({"username": "Gilbert"}) because Context is deprecated. When I used Context, I got an error > TypeError: context must be a dict rather than Context
text_content = render_to_string('receipt_email.txt', context, request=request)
html_content = render_to_string('receipt_email.html', context, request=request)
try:
#I used EmailMultiAlternatives because I wanted to send both text and html
emailMessage = EmailMultiAlternatives(subject=emailSubject, body=text_content, from_email=emailOfSender, to=[emailOfRecipient,], reply_to=[emailOfSender,])
emailMessage.attach_alternative(html_content, "text/html")
emailMessage.send(fail_silently=False)
except SMTPException as e:
print('There was an error sending an email: ', e)
error = {'message': ",".join(e.args) if len(e.args) > 0 else 'Unknown Error'}
raise serializers.ValidationError(error)
Important! So how does render_to_string
get receipt_email.txt
and receipt_email.html
?
In my settings.py
, I have TEMPLATES
and below is how it looks
Pay attention to DIRS
, there is this line os.path.join(BASE_DIR, 'templates', 'email_templates')
.This line is what makes my templates accessible. In my project_dir, I have a folder called templates
, and a sub_directory called email_templates
like this project_dir->templates->email_templates
. My templates receipt_email.txt
and receipt_email.html
are under the email_templates
sub_directory.
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates'), os.path.join(BASE_DIR, 'templates', 'email_templates')],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
Let me just add that, my recept_email.txt
looks like this;
Dear {{name}},
Here is the text version of the email from template
And, my receipt_email.html
looks like this;
Dear {{name}},
<h1>Now here is the html version of the email from the template</h1>
Your docker host exposes an adapter to all the containers. Assuming you are on recent ubuntu, you can run
ip addr
This will give you a list of network adapters, one of which will look something like
3: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
link/ether 22:23:6b:28:6b:e0 brd ff:ff:ff:ff:ff:ff
inet 172.17.42.1/16 scope global docker0
inet6 fe80::a402:65ff:fe86:bba6/64 scope link
valid_lft forever preferred_lft forever
You will need to tell rabbit/mongo to bind to that IP (172.17.42.1). After that, you should be able to open connections to 172.17.42.1 from within your containers.
If you're looking to print specific data that you already have access to, whether it's from a Store, AJAX, or available elsewhere, you can leverage my library react-print.
https://github.com/captray/react-print
It makes creating print templates much easier (assuming you already have a dependency on react). You just need to tag your HTML appropriately.
This ID should be added higher up in your actual DOM tree to exclude everything except the "print mount" below.
<div id="react-no-print">
This is where your react-print component will mount and wrap your template that you create:
<div id="print-mount"></div>
An example looks something like this:
var PrintTemplate = require('react-print');
var ReactDOM = require('react-dom');
var React = require('react');
var MyTemplate = React.createClass({
render() {
return (
<PrintTemplate>
<p>Your custom</p>
<span>print stuff goes</span>
<h1>Here</h1>
</PrintTemplate>
);
}
});
ReactDOM.render(<MyTemplate/>, document.getElementById('print-mount'));
It's worth noting that you can create new or utilize existing child components inside of your template, and everything should render fine for printing.
Using Java 8 stream API:
String[] keys = new String[0];
// A map for keys and their count
Map<String, Long> keyCountMap = Arrays.stream(keys).
collect(Collectors.groupingBy(Function.identity(), Collectors.counting()));
int uniqueItemIdCount= keyCountMap.size();
You'll need to clear out your cache to have it completely wiped. this help page from git will help you out. (it helped me) http://help.github.com/remove-sensitive-data/
Here is how to restore a backup as an additional db with a unique db name.
For SQL 2005 this works very quickly. I am sure newer versions will work the same.
First, you don't have to take your original db offline. But for safety sake, I like to. In my example, I am going to mount a clone of my "billing" database and it will be named "billingclone".
1) Make a good backup of the billing database
2) For safety, I took the original offline as follows:
3) Open a new Query window
**IMPORTANT! Keep this query window open until you are all done! You need to restore the db from this window!
Now enter the following code:
-- 1) free up all USER databases
USE master;
GO
-- 2) kick all other users out:
ALTER DATABASE billing SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
GO
-- 3) prevent sessions from re-establishing connection:
ALTER DATABASE billing SET OFFLINE;
3) Next, in Management Studio, rt click Databases in Object Explorer, choose "Restore Database"
4) enter new name in "To Database" field. I.E. billingclone
5) In Source for Restore, click "From Device" and click the ... navigate button
6) Click Add and navigate to your backup
7) Put a checkmark next to Restore (Select the backup sets to restore)
8) next select the OPTIONS page in upper LH corner
9) Now edit the database file names in RESTORE AS. Do this for both the db and the log. I.E. billingclone.mdf and billingclone_log.ldf
10) now hit OK and wait for the task to complete.
11) Hit refresh in your Object Explorer and you will see your new db
12) Now you can put your billing db back online. Use the same query window you used to take billing offline. Use this command:
-- 1) free up all USER databases
USE master; GO
-- 2) restore access to all users:
ALTER DATABASE billing SET MULTI_USER WITH ROLLBACK IMMEDIATE;GO
-- 3) put the db back online:
ALTER DATABASE billing SET ONLINE;
done!
One main difference I noticed between ViewData and ViewBag is:
ViewData : it will return object does not matter what you have assigned into this and need to typecast again back to the original type.
ViewBag : it is enough smart to return exact type what you have assigned to it it does not matter weather you have assigned simple type (i.e. int, string etc.) or complex type.
Ex: Controller code.
namespace WebApplication1.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
Products p1 = new Products();
p1.productId = 101;
p1.productName = "Phone";
Products p2 = new Products();
p2.productId = 102;
p2.productName = "laptop";
List<Products> products = new List<Products>();
products.Add(p1);
products.Add(p2);
ViewBag.Countries = products;
return View();
}
}
public class Products
{
public int productId { get; set; }
public string productName { get; set; }
}
}
View Code.
<ul>
@foreach (WebApplication1.Controllers.Products item in ViewBag.Countries)
{
<li>@item.productId @item.productName</li>
}
</ul>

You can simply
git checkout -b my-branch origin/whatever
in the first place. If you set branch.autosetupmerge
or branch.autosetuprebase
(my favorite) to always
(default is true
), my-branch
will automatically track origin/whatever
.
See git help config
.

function change_css(){
document.getElementById('result').style.cssText = 'padding:20px; background-color:#b2b2ff; color:#0c0800; border:1px solid #0c0800; font-size:22px;';

To get rid of error:
Type '"text"' is not assignable to type '"json"'.
Use
responseType: 'text' as 'json'
import { HttpClient, HttpHeaders } from '@angular/common/http';
.....
return this.http
.post<string>(
this.baseUrl + '/Tickets/getTicket',
JSON.stringify(value),
{ headers, responseType: 'text' as 'json' }
)
.map(res => {
return res;
})
.catch(this.handleError);
Use:
from datetime import datetime
today = datetime.today()
datem = datetime(today.year, today.month, 1)
I assume you want the first of the month.
It will not work like this, put both images as background images:
.bg-img {
background:url(images/yourImg.jpg) no-repeat 0 0;
}
.bg-img:hover {
background:url(images/yourImg-1.jpg) no-repeat 0 0;
}
There is a generic solution:
Lets say you have a controller named Admin where you put content for authorized users.
Then, you can override the Initialize
or OnAuthorization
methods of Admin controller and write redirect to login page logic on session timeout in these methods as described:
protected override void OnAuthorization(System.Web.Mvc.AuthorizationContext filterContext)
{
//lets say you set session value to a positive integer
AdminLoginType = Convert.ToInt32(filterContext.HttpContext.Session["AdminLoginType"]);
if (AdminLoginType == 0)
{
filterContext.HttpContext.Response.Redirect("~/login");
}
base.OnAuthorization(filterContext);
}
If you Want to run Batch Subscribe on a List using Mailchimp API . Then you can use the below function.
/**
* Mailchimp API- List Batch Subscribe added function
*
* @param array $data Passed you data as an array format.
* @param string $apikey your mailchimp api key.
*
* @return mixed
*/
function batchSubscribe(array $data, $apikey)
{
$auth = base64_encode('user:' . $apikey);
$json_postData = json_encode($data);
$ch = curl_init();
$dataCenter = substr($apikey, strpos($apikey, '-') + 1);
$curlopt_url = 'https://' . $dataCenter . '.api.mailchimp.com/3.0/batches/';
curl_setopt($ch, CURLOPT_URL, $curlopt_url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json',
'Authorization: Basic ' . $auth));
curl_setopt($ch, CURLOPT_USERAGENT, 'PHP-MCAPI/3.0');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_postData);
$result = curl_exec($ch);
return $result;
}
Function Use And Data format for Batch Operations:
<?php
$apikey = 'Your MailChimp Api Key';
$list_id = 'Your list ID';
$servername = 'localhost';
$username = 'Youre DB username';
$password = 'Your DB password';
$dbname = 'Your DB Name';
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die('Connection failed: ' . $conn->connect_error);
}
$sql = 'SELECT * FROM emails';// your SQL Query goes here
$result = $conn->query($sql);
$finalData = [];
if ($result->num_rows > 0) {
// output data of each row
while ($row = $result->fetch_assoc()) {
$individulData = array(
'apikey' => $apikey,
'email_address' => $row['email'],
'status' => 'subscribed',
'merge_fields' => array(
'FNAME' => 'eastwest',
'LNAME' => 'rehab',
)
);
$json_individulData = json_encode($individulData);
$finalData['operations'][] =
array(
"method" => "POST",
"path" => "/lists/$list_id/members/",
"body" => $json_individulData
);
}
}
$api_response = batchSubscribe($finalData, $apikey);
print_r($api_response);
$conn->close();
Also, You can found this code in my Github gist. GithubGist Link
Reference Documentation: Official
Usually, I replace a recursive algorithm by an iterative algorithm by pushing the parameters that would normally be passed to the recursive function onto a stack. In fact, you are replacing the program stack by one of your own.
var stack = [];
stack.push(firstObject);
// while not empty
while (stack.length) {
// Pop off end of stack.
obj = stack.pop();
// Do stuff.
// Push other objects on the stack as needed.
...
}
Note: if you have more than one recursive call inside and you want to preserve the order of the calls, you have to add them in the reverse order to the stack:
foo(first);
foo(second);
has to be replaced by
stack.push(second);
stack.push(first);
Edit: The article Stacks and Recursion Elimination (or Article Backup link) goes into more details on this subject.
Combining the ideas from:
Levon or Jesse, Faheel and ddrscott
with my formatting suggestion, you could write your query as:
query = ('SELECT'
' action.descr as "action"'
',role.id as role_id'
',role.descr as role'
' FROM'
' public.role_action_def'
',public.role'
',public.record_def'
',public.action'
' WHERE'
' role.id = role_action_def.role_id'
' AND'
' record_def.id = role_action_def.def_id'
' AND'
' action.id = role_action_def.action_id'
' AND'
' role_action_def.account_id = ?' # account_id
' AND'
' record_def.account_id = ?' # account_id
' AND'
' def_id = ?' # def_id
)
vars = (account_id, account_id, def_id) # A tuple of the query variables
cursor.execute(query, vars) # Using Python's sqlite3 module
Or like:
vars = []
query = ('SELECT'
' action.descr as "action"'
',role.id as role_id'
',role.descr as role'
' FROM'
' public.role_action_def'
',public.role'
',public.record_def'
',public.action'
' WHERE'
' role.id = role_action_def.role_id'
' AND'
' record_def.id = role_action_def.def_id'
' AND'
' action.id = role_action_def.action_id'
' AND'
' role_action_def.account_id = '
vars.append(account_id) or '?'
' AND'
' record_def.account_id = '
vars.append(account_id) or '?'
' AND'
' def_id = '
vars.append(def_id) or '?'
)
cursor.execute(query, tuple(vars)) # Using Python's sqlite3 module
Which could be interesting together with 'IN' and 'vars.extend(options) or n_options(len(options))', where:
def n_options(count):
return '(' + ','.join(count*'?') + ')'
Or with the hint from darkfeline, that you might still make mistakes with those leading spaces and separators and also with named placeholders:
SPACE_SEP = ' '
COMMA_SEP = ', '
AND_SEP = ' AND '
query = SPACE_SEP.join((
'SELECT',
COMMA_SEP.join((
'action.descr as "action"',
'role.id as role_id',
'role.descr as role',
)),
'FROM',
COMMA_SEP.join((
'public.role_action_def',
'public.role',
'public.record_def',
'public.action',
)),
'WHERE',
AND_SEP.join((
'role.id = role_action_def.role_id',
'record_def.id = role_action_def.def_id',
'action.id = role_action_def.action_id',
'role_action_def.account_id = :account_id',
'record_def.account_id = :account_id',
'def_id = :def_id',
)),
))
vars = {'account_id':account_id,'def_id':def_id} # A dictionary of the query variables
cursor.execute(query, vars) # Using Python's sqlite3 module
See documentation of Cursor.execute-function.

I agree with Joris; it seems like you should be doing this differently, like with numpy record arrays. Modifying "option 2" from this great answer, you could do it like this:
import pandas
import numpy
dtype = [('Col1','int32'), ('Col2','float32'), ('Col3','float32')]
values = numpy.zeros(20, dtype=dtype)
index = ['Row'+str(i) for i in range(1, len(values)+1)]
df = pandas.DataFrame(values, index=index)
Maybe you can run this regex first to see if the line is all caps:
^[A-Z \d\W]+$
That will match only if it's a line like THING P1 MUST CONNECT TO X2.
Otherwise, you should be able to pull out the individual uppercase phrases with this:
[A-Z][A-Z\d]+
That should match "P1" and "J236" in The thing P1 must connect to the J236 thing in the Foo position.
The error you're getting appears to be the result of the fact that there is no underscore between "chartered" and "flight" in the table name. I assume you want something like this where the name of the table is chartered_flight
.
CREATE TABLE chartered_flight(flight_no NUMBER(4) PRIMARY KEY
, customer_id NUMBER(6) REFERENCES customer(customer_id)
, aircraft_no NUMBER(4) REFERENCES aircraft(aircraft_no)
, flight_type VARCHAR2 (12)
, flight_date DATE NOT NULL
, flight_time INTERVAL DAY TO SECOND NOT NULL
, takeoff_at CHAR (3) NOT NULL
, destination CHAR (3) NOT NULL)
Generally, there is no benefit to declaring a column as CHAR(3)
rather than VARCHAR2(3)
. Declaring a column as CHAR(3)
doesn't force there to be three characters of (useful) data. It just tells Oracle to space-pad data with fewer than three characters to three characters. That is unlikely to be helpful if someone inadvertently enters an incorrect code. Potentially, you could declare the column as VARCHAR2(3)
and then add a CHECK
constraint that LENGTH(takeoff_at) = 3
.
CREATE TABLE chartered_flight(flight_no NUMBER(4) PRIMARY KEY
, customer_id NUMBER(6) REFERENCES customer(customer_id)
, aircraft_no NUMBER(4) REFERENCES aircraft(aircraft_no)
, flight_type VARCHAR2 (12)
, flight_date DATE NOT NULL
, flight_time INTERVAL DAY TO SECOND NOT NULL
, takeoff_at CHAR (3) NOT NULL CHECK( length( takeoff_at ) = 3 )
, destination CHAR (3) NOT NULL CHECK( length( destination ) = 3 )
)
Since both takeoff_at
and destination
are airport codes, you really ought to have a separate table of valid airport codes and define foreign key constraints between the chartered_flight
table and this new airport_code
table. That ensures that only valid airport codes are added and makes it much easier in the future if an airport code changes.
And from a naming convention standpoint, since both takeoff_at
and destination
are airport codes, I would suggest that the names be complementary and indicate that fact. Something like departure_airport_code
and arrival_airport_code
, for example, would be much more meaningful.
Now there is a very useful npm package for this: buffer

It tries to provide an API that is 100% identical to node's Buffer API and allow:

This might be very late answer. But this chart kills it.

We tried a few applications, both trials of commercial products and freely available ones. Ultimately, it was the trial edition of the Team Test Load Agent software that we tried. It definitely works great and is fairly simple to use. In the long run, it bolstered our argument to move to Team Foundation Server and equip all parts of the department with the appropriate tooling.
The obvious downside, however, is the price.
Guys don't forget to call xmlWriter.Close() and xmlWriter.Dispose() or else your string won't finish creating. It will just be an empty string
Example: index = False
import pandas as pd
writer = pd.ExcelWriter("dataframe.xlsx", engine='xlsxwriter')
dataframe.to_excel(writer,sheet_name = dataframe, index=False)
writer.save()
First you create the EditText in the xml file and assign an id, eg con_pag_etPesquisa. After that, we will create two lists, where one is the list view and the other to receive the same content but will remain as a backup. Before moving objects to lists first initializes Them the below:
//Declaring
public EditText etPesquisa;
public ContasPagarAdapter adapterNormal;
public List<ContasPagar> lstBkp;
public List<ContasPagar> lstCp;
//Within the onCreate method, type the following:
etPesquisa = (EditText) findViewById(R.id.con_pag_etPesquisa);
etPesquisa.addTextChangedListener(new TextWatcher(){
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3){
filter(String.valueOf(cs));
}
@Override
public void beforeTextChanged(CharSequence cs, int arg1, int arg2, int arg3){
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable e){
}
});
//Before moving objects to lists first initializes them as below:
lstCp = new ArrayList<ContasPagar>();
lstBkp = new ArrayList<ContasPagar>();
//When you add objects to the main list, repeat the procedure also for bkp list, as follows:
lstCp.add(cp);
lstBkp.add(cp);
//Now initializes the adapter and let the listener, as follows:
adapterNormal = new ContasPagarAdapter(ContasPagarActivity.this, lstCp);
lvContasPagar.setAdapter(adapterNormal);
lvContasPagar.setOnItemClickListener(verificaClickItemContasPagar(lstCp));
//Now create the methods inside actito filter the text entered by the user, as follows:
public void filter(String charText){
charText = charText.toLowerCase();
lstCp.clear();
if (charText.length() == 0){
lstCp.addAll(lstBkp);
appendAddItem(lstBkp);
}
else {
for (int i = 0; i < lstBkp.size(); i++){
if((lstBkp.get(i).getNome_lancamento() + " - " + String.valueOf(lstBkp.get(i).getCodigo())).toLowerCase().contains(charText)){
lstCp.add(lstBkp.get(i));
}
}
appendAddItem(lstCp);
}
}
private void appendAddItem(final List<ContasPagar> novaLista){
runOnUiThread(new Runnable(){
@Override
public void run(){
adapterNormal.notifyDataSetChanged();
}
});
}
Emm... Why not to use something like this?

For VS2010 and above (VS2010 needs a plugin). If you have checked/set the options of the tab size in Visual Studio but it still won't work. Then check if you have a .editorconfig file in your project! This will override the Visual Studio settings. Edit the tab-size in that file.
This can happen if you install an Angular application in your project with the Angular-Cli.
Under Windows 7, open the Event Viewer. You can do this the way Gishu suggested for XP, typing eventvwr
from the command line, or by opening the Control Panel, selecting System and Security, then Administrative Tools and finally Event Viewer. It may require UAC approval or an admin password.
In the left pane, expand Windows Logs and then System. You can filter the logs with Filter Current Log... from the Actions pane on the right and selecting "Service Control Manager." Or, depending on why you want this information, you might just need to look through the Error entries.
The actual log entry pane (not shown) is pretty user-friendly and self-explanatory. You'll be looking for messages like the following:
"The Praxco Assistant service entered the stopped state."
"The Windows Image Acquisition (WIA) service entered the running state."
"The MySQL service terminated unexpectedly. It has done this 3 time(s)."
It's not clear what you want, or whether you want this trick to work with different targets, or whether you've defined these targets elsewhere, or what version of Make you're using, but what the heck, I'll go out on a limb:

CXXFLAGS := ${CXXFLAGS} -DDESKTOP_TEST
test:
$(info ************ TEST VERSION ************)
else
release:
$(info ************ RELEASE VERSIOIN **********)
endif
You can do it without setlocal
, because of the setlocal
command the variable won't survive an endlocal
because it was created in setlocal
. In this way the variable will be defined the right way.
To do that use this code:
set var1=A
set var2=B
set AB=hi
call set newvar=%%%var1%%var2%%%
echo %newvar%
Note: You MUST use call
before you set the variable or it won't work.

How about:
using (ModelName context = new ModelName())

ModelName is the class auto-generated by the designer, which inherits from ObjectContext

On modern macOS, the correct path is /Library/Java/JavaVirtualMachines
.
You can also avail yourself of the command /usr/libexec/java_home
, which will scan that directory for you and return a list.
Somthing like this should workL
SELECT BookingId, StartTime
FROM Booking
WHERE StartTime between dateadd(hour, -1, getdate()) and getdate()
Python os module
Specifically for Python 3.6/3.7:
os.name
: The name of the operating system dependent module imported. The following names have currently been registered: 'posix', 'nt', 'java'.
In your case, you want to check for 'nt' as os.name
output:
import os
if os.name == 'nt':
...
There is also a note on os.name
:
See also
sys.platform
has a finer granularity.os.uname()
gives system-dependent version information.The platform module provides detailed checks for the system’s identity.
I do a mix of edem's answer and your second code. This way, I have the benefits of common getter/setters (code completion in your IDE), ease of coding if I want, exceptions due to inexistent properties (great for discovering typos: $foo->naem
instead of $foo->name
), read only properties and compound properties.
class Foo
{
private $_bar;
private $_baz;
public function getBar()
{
return $this->_bar;
}
public function setBar($value)
{
$this->_bar = $value;
}
public function getBaz()
{
return $this->_baz;
}
public function getBarBaz()
{
return $this->_bar . ' ' . $this->_baz;
}
public function __get($var)
{
$func = 'get'.$var;
if (method_exists($this, $func))
{
return $this->$func();
} else {
throw new InexistentPropertyException("Inexistent property: $var");
}
}
public function __set($var, $value)
{
$func = 'set'.$var;
if (method_exists($this, $func))
{
$this->$func($value);
} else {
if (method_exists($this, 'get'.$var))
{
throw new ReadOnlyException("property $var is read-only");
} else {
throw new InexistentPropertyException("Inexistent property: $var");
}
}
}
}
When you visited https://localhost previously at some point it not only visited this over a secure channel (https rather than http), it also told your browser, using a special HTTP header: Strict-Transport-Security (often abbreviated to HSTS), that it should ONLY use https for all future visits.
This is a security feature web servers can use to prevent people being downgraded to http (either intentionally or by some evil party).
However if you then then turn off your https server, and just want to browse http you can't (by design - that's the point of this security feature).
HSTS also does prevents you from accepting and skipping past certificate errors.
To reset this, so HSTS is no longer set for localhost, type the following in your Chrome address bar:
chrome://net-internals/#hsts
Where you will be able to delete this setting for "localhost".
You might also want to find out what was setting this to avoid this problem in future!
Note that for other sites (e.g. www.google.com) these are "preloaded" into the Chrome code and so cannot be removed. When you query them at chrome://net-internals/#hsts you will see them listed as static
HSTS entries.
And finally note that Google has started preloading HSTS for the entire .dev domain: https://ma.ttias.be/chrome-force-dev-domains-https-via-preloaded-hsts/
Apart from string interpolation, you can also call a function using back-tick.
var sayHello = function () {
console.log('Hello', arguments);
}
// To call this function using ``
sayHello`some args`; // Check console for the output
// Or
sayHello`
some args
`;
Check styled component. They use it heavily.
The issue is that your two Integer objects are just that, objects. They do not match because you are comparing your two object references, not the values within. Obviously .equals
is overridden to provide a value comparison as opposed to an object reference comparison.
If you have to use the same page as the action, you cannot use onSubmit="window.close();"
as it will close the window before the response is received. You have to dinamycally output a JS snippet that closes the window after the SQL data is processed. It would however be far more elegant to use another page as the form action.
I wrote an example for a custom Timestamp.class
serialization/deserialization, but you could use it for what ever you want.
When creating the object mapper do something like this:
public class JsonUtils {
public static ObjectMapper objectMapper = null;
static {
objectMapper = new ObjectMapper();
SimpleModule s = new SimpleModule();
s.addSerializer(Timestamp.class, new TimestampSerializerTypeHandler());
s.addDeserializer(Timestamp.class, new TimestampDeserializerTypeHandler());
objectMapper.registerModule(s);
};
}
for example in java ee
you could initialize it with this:
import java.time.LocalDateTime;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.module.SimpleModule;
@Provider
public class JacksonConfig implements ContextResolver<ObjectMapper> {
private final ObjectMapper objectMapper;
public JacksonConfig() {
objectMapper = new ObjectMapper();
SimpleModule s = new SimpleModule();
s.addSerializer(Timestamp.class, new TimestampSerializerTypeHandler());
s.addDeserializer(Timestamp.class, new TimestampDeserializerTypeHandler());
objectMapper.registerModule(s);
};
@Override
public ObjectMapper getContext(Class<?> type) {
return objectMapper;
}
}
where the serializer should be something like this:
import java.io.IOException;
import java.sql.Timestamp;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;
public class TimestampSerializerTypeHandler extends JsonSerializer<Timestamp> {
@Override
public void serialize(Timestamp value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonProcessingException {
String stringValue = value.toString();
if(stringValue != null && !stringValue.isEmpty() && !stringValue.equals("null")) {
jgen.writeString(stringValue);
} else {
jgen.writeNull();
}
}
@Override
public Class<Timestamp> handledType() {
return Timestamp.class;
}
}
and deserializer something like this:
import java.io.IOException;
import java.sql.Timestamp;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.JsonDeserializer;
import com.fasterxml.jackson.databind.SerializerProvider;
public class TimestampDeserializerTypeHandler extends JsonDeserializer<Timestamp> {
@Override
public Timestamp deserialize(JsonParser jp, DeserializationContext ds) throws IOException, JsonProcessingException {
SqlTimestampConverter s = new SqlTimestampConverter();
String value = jp.getValueAsString();
if(value != null && !value.isEmpty() && !value.equals("null"))
return (Timestamp) s.convert(Timestamp.class, value);
return null;
}
@Override
public Class<Timestamp> handledType() {
return Timestamp.class;
}
}
The generic view of a loop is
for (initialization; condition; increment-decrement){}
The first part initializes the code. The second part is the condition that will continue to run the loop as long as it is true. The last part is what will be run after each iteration of the loop. The last part is typically used to increment or decrement a counter, but it doesn't have to.
You should take a look at the List
object. Lists tend to be better at changing dynamically like you want. Arrays not so much...
I've been using an Evaluation copy of Sublime Text
. What's good is it doesn't really expire.
It's been good so far and was really easy to get started with.
Currently there is a far simpler solution than the ones already provided. When running your application you just have to pass along the threaded=True
parameter to the app.run()
call, like:
app.run(host="your.host", port=4321, threaded=True)
Another option as per what we can see in the werkzeug docs, is to use the processes
parameter, which receives a number > 1 indicating the maximum number of concurrent processes to handle:
- threaded – should the process handle each request in a separate thread?
- processes – if greater than 1 then handle each request in a new process up to this maximum number of concurrent processes.
Something like:
app.run(host="your.host", port=4321, processes=3) #up to 3 processes
More info on the run()
method here, and the blog post that led me to find the solution and api references.
Note: on the Flask docs on the run()
methods it's indicated that using it in a Production Environment is discouraged because (quote): "While lightweight and easy to use, Flask’s built-in server is not suitable for production as it doesn’t scale well."
However, they do point to their Deployment Options page for the recommended ways to do this when going for production.
If the file is native to your system (certainly no guarantees of that), then Node can help you out:
var os = require('os');
a.split(os.EOL);
This is usually more useful for constructing output strings from Node though, for platform portability.
I was facing the same error. The solution that worked for me is:
From the server end, while returning JSON response, change the content-type: text/html
Now the browsers (Chrome, Firefox and IE8) do not give an error.
@Chris Haas has explained very well how to use itextSharp
to convert HTML
to PDF
, very helpful
my add is:
By using HtmlTextWriter
I put html tags inside HTML
table + inline CSS i got my PDF as I wanted without using XMLWorker
.
Edit: adding sample code:
ASPX page:
<asp:Panel runat="server" ID="PendingOrdersPanel">
<!-- to be shown on PDF-->
<table style="border-spacing: 0;border-collapse: collapse;width:100%;display:none;" >

if (PendingOrdersGV.Rows.Count > 0)
{
//to allow paging=false & change style.
PendingOrdersGV.HeaderStyle.ForeColor = System.Drawing.Color.Black;

PendingOrdersGV.Font.Name = "Tahoma";
PendingOrdersGV.DataSource = clsBP.get_PendingOrders(lbl_BP_Id.Text);
PendingOrdersGV.AllowPaging = false;
PendingOrdersGV.Columns[0].Visible = false; //export won't work if there's a link in the gridview
PendingOrdersGV.DataBind();
//to PDF code --Sam
string attachment = "attachment; filename=report.pdf";
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/pdf";
StringWriter stw = new StringWriter();
HtmlTextWriter htextw = new HtmlTextWriter(stw);
htextw.AddStyleAttribute("font-size", "8pt");
htextw.AddStyleAttribute("color", "Grey");
PendingOrdersPanel.RenderControl(htextw); //Name of the Panel
Document document = new Document();
document = new Document(PageSize.A4, 5, 5, 15, 5);
FontFactory.GetFont("Tahoma", 50, iTextSharp.text.BaseColor.BLUE);
PdfWriter.GetInstance(document, Response.OutputStream);
document.Open();
StringReader str = new StringReader(stw.ToString());
HTMLWorker htmlworker = new HTMLWorker(document);
htmlworker.Parse(str);
document.Close();
Response.Write(document);
}
}
of course include iTextSharp Refrences to cs file
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.text.html.simpleparser;
using iTextSharp.tool.xml;
Hope this helps!
Thank you
Are you thinking about something like this?
$('ul li').each(function(i)
{
$(this).attr('rel'); // This is your rel value
});
I had the same problem, put the ! outside the brackets;
while ! [ -f /tmp/list.txt ];
do
echo "#"
sleep 1
done
Also, if you add an echo inside the loop it will tell you if you are getting into the loop or not.

END CONTRATO,

The following will give you the hex encoding for the low byte of each character, which looks like what you're asking for:
StringBuilder sb = new StringBuilder();
foreach (char c in asciiString)
{
uint i = (uint)c;
sb.AppendFormat("{0:X2}", (i & 0xff));
}
return sb.ToString();
If you actually want to filter blank lines from a file then you may try this:
(gc $source_file).Trim() | ? {$_.Length -gt 0}
This code compiles and works for me. It converts a double to a string using the calls you tried.
public class TestDouble {
public static void main(String[] args) {
double total = 44;
String total2 = Double.toString(total);
System.out.println("Double is " + total2);
}
}
I am puzzled by your seeing the NumberFormatException. Look at the stack trace. I'm guessing you have other code that you are not showing in your example that is causing that exception to be thrown.
You could use PHP's file_get_contents();
<?php
$script = file_get_contents('javascriptFile.js');
echo "<script>".$script."</script>";
?>
For more information on the function:
Having a "table" in memory that needs lookups, sorting, and arbitrary aggregation really does call out for SQL. You said you tried SQLite, but did you realize that SQLite can use an in-memory-only database?
connection = sqlite3.connect(':memory:')
Then you can create/drop/query/update tables in memory with all the functionality of SQLite and no files left over when you're done. And as of Python 2.5, sqlite3
is in the standard library, so it's not really "overkill" IMO.
Here is a sample of how one might create and populate the database:
import csv
import sqlite3
db = sqlite3.connect(':memory:')
def init_db(cur):
cur.execute('''CREATE TABLE foo (
Row INTEGER,
Name TEXT,
Year INTEGER,
Priority INTEGER)''')
def populate_db(cur, csv_fp):
rdr = csv.reader(csv_fp)
cur.executemany('''
INSERT INTO foo (Row, Name, Year, Priority)
VALUES (?,?,?,?)''', rdr)
cur = db.cursor()
init_db(cur)
populate_db(cur, open('my_csv_input_file.csv'))
db.commit()
If you'd really prefer not to use SQL, you should probably use a list of dictionaries:
lod = [ ] # "list of dicts"
def populate_lod(lod, csv_fp):
rdr = csv.DictReader(csv_fp, ['Row', 'Name', 'Year', 'Priority'])
lod.extend(rdr)
def query_lod(lod, filter=None, sort_keys=None):
if filter is not None:
lod = (r for r in lod if filter(r))
if sort_keys is not None:
lod = sorted(lod, key=lambda r:[r[k] for k in sort_keys])
else:
lod = list(lod)
return lod
def lookup_lod(lod, **kw):
for row in lod:
for k,v in kw.iteritems():
if row[k] != str(v): break
else:
return row
return None
Testing then yields:
>>> lod = []
>>> populate_lod(lod, csv_fp)
>>>
>>> pprint(lookup_lod(lod, Row=1))
{'Name': 'Cat', 'Priority': '1', 'Row': '1', 'Year': '1998'}
>>> pprint(lookup_lod(lod, Name='Aardvark'))
{'Name': 'Aardvark', 'Priority': '1', 'Row': '4', 'Year': '2000'}
>>> pprint(query_lod(lod, sort_keys=('Priority', 'Year')))
[{'Name': 'Cat', 'Priority': '1', 'Row': '1', 'Year': '1998'},
{'Name': 'Dog', 'Priority': '1', 'Row': '3', 'Year': '1999'},
{'Name': 'Aardvark', 'Priority': '1', 'Row': '4', 'Year': '2000'},
{'Name': 'Wallaby', 'Priority': '1', 'Row': '5', 'Year': '2000'},
{'Name': 'Fish', 'Priority': '2', 'Row': '2', 'Year': '1998'},
{'Name': 'Zebra', 'Priority': '3', 'Row': '6', 'Year': '2001'}]
>>> pprint(query_lod(lod, sort_keys=('Year', 'Priority')))
[{'Name': 'Cat', 'Priority': '1', 'Row': '1', 'Year': '1998'},
{'Name': 'Fish', 'Priority': '2', 'Row': '2', 'Year': '1998'},
{'Name': 'Dog', 'Priority': '1', 'Row': '3', 'Year': '1999'},
{'Name': 'Aardvark', 'Priority': '1', 'Row': '4', 'Year': '2000'},
{'Name': 'Wallaby', 'Priority': '1', 'Row': '5', 'Year': '2000'},
{'Name': 'Zebra', 'Priority': '3', 'Row': '6', 'Year': '2001'}]
>>> print len(query_lod(lod, lambda r:1997 <= int(r['Year']) <= 2002))
6
>>> print len(query_lod(lod, lambda r:int(r['Year'])==1998 and int(r['Priority']) > 2))

Personally I like the SQLite version better since it preserves your types better (without extra conversion code in Python) and easily grows to accommodate future requirements. But then again, I'm quite comfortable with SQL, so YMMV.
Are you setting up a local 'm4
' directory? e.g.,
> aclocal -I m4 --install
Some packages come with an autogen.sh
or initgen.sh
shell script to run glibtoolize, autoheader, autoconf, automake. Here's an autogen.sh
script I use:
#! /bin/sh
case `uname` in Darwin*) glibtoolize --copy ;;
*) libtoolize --copy ;; esac
autoheader
aclocal -I m4 --install
autoconf
automake --foreign --add-missing --force-missing --copy
EDIT
You may need to add ACLOCAL_AMFLAGS = -I m4
to the top-level Makefile.am
.
This tripped me up today, but I realized it was because on Android 9.0 (Pie), Do Not Disturb by default also hides all notifications, rather than just silencing them like in Android 8.1 (Oreo) and before. This doesn't apply to notifications.
I like having DND on for my development device, so going into the DND settings and changing the setting to simply silence the notifications (but not hide them) fixed it for me.
You can import modules but not text files. If you want to print the content do the following:
Open a text file for reading:
f = open('words.txt', 'r')
Store content in a variable:
content = f.read()
Print content of this file:
print(content)
After you're done close a file:
f.close()
std::list
does not provide a search method. You can iterate over the list and check if the element exists or use std::find
. But I think for your situation std::set
is more preferable. The former will take O(n)
time but later will take O(lg(n))
time to search.
You can simply use:
int my_var = 3;
std::set<int> mySet {1, 2, 3, 4};
if(mySet.find(myVar) != mySet.end()){
//do whatever
}
First you need to start karma server with
karma start
Then, you can use grep to filter a specific test or describe block:
karma run -- --grep=testDescriptionFilter
Similar to this answer but more a more "pythonic" way to iterate over the digis would be:
while number:
# "pop" the rightmost digit
number, digit = divmod(number, 10)
In your case i see the ternary operator as redundant. You could assign the variable directly to the expression, using ||, && operators.
!defaults.slideshowWidth ? defaults.slideshowWidth = obj.find('img').width()+'px' : null ;
will become :
defaults.slideshowWidth = defaults.slideshowWidth || obj.find('img').width()+'px';
It's more clear, it's more "javascript" style.
Why nobody mentions matchMedia?
if (window.matchMedia("(min-width: 400px)").matches) {
/* the viewport is at least 400 pixels wide */
} else {
/* the viewport is less than 400 pixels wide */
}
Did not test that much, but tested with android default and android chrome browsers, desktop chrome, so far it looks like it works well.
Of course it does not return number value, but returns boolean - if matches or not, so might not exactly fit the question but that's what we want anyway and probably the author of question wants.
Dim myRow() As Data.DataRow
myRow = dt.Select("MyColumnName = 'SomeColumnTitle'")
myRow(0)("SomeOtherColumnTitle") = strValue
Code above instantiates a DataRow. Where "dt" is a DataTable, you get a row by selecting any column (I know, sounds backwards). Then you can then set the value of whatever row you want (I chose the first row, or "myRow(0)"), for whatever column you want.
You might need a GLOBAL TEMPORARY TABLE.
In Oracle these are created once and then when invoked the data is private to your session.
Try something like this...
CREATE GLOBAL TEMPORARY TABLE temp_number
( number_column NUMBER( 10, 0 )
)
ON COMMIT DELETE ROWS;
BEGIN
INSERT INTO temp_number
( number_column )
( select distinct sgbstdn_pidm
from sgbstdn
where sgbstdn_majr_code_1 = 'HS04'
and sgbstdn_program_1 = 'HSCOMPH'
);
FOR pidms_rec IN ( SELECT number_column FROM temp_number )
LOOP
-- Do something here
NULL;
END LOOP;
END;
