Try this example and see if it fits your needs, there are three main aspects to it.
Line.Stretch is set to fill.
For horizontal lines the VerticalAlignment of the line is set Bottom, and for VerticalLines the HorizontalAlignment is set to Right.
We then need to tell the line how many rows or columns to span, this is done by binding to either RowDefinitions or ColumnDefintions count property.
<Style x:Key="horizontalLineStyle" TargetType="Line" BasedOn="{StaticResource lineStyle}">
<Setter Property="X2" Value="1" />
<Setter Property="VerticalAlignment" Value="Bottom" />
<Setter Property="Grid.ColumnSpan"
Value="{Binding
Path=ColumnDefinitions.Count,
RelativeSource={RelativeSource AncestorType=Grid}}"/>
</Style>
<Style x:Key="verticalLineStyle" TargetType="Line" BasedOn="{StaticResource lineStyle}">
<Setter Property="Y2" Value="1" />
<Setter Property="HorizontalAlignment" Value="Right" />
<Setter Property="Grid.RowSpan"
Value="{Binding
Path=RowDefinitions.Count,
RelativeSource={RelativeSource AncestorType=Grid}}"/>
</Style>
</Grid.Resources>
<Grid.RowDefinitions>
<RowDefinition Height="20"/>
<RowDefinition Height="20"/>
<RowDefinition Height="20"/>
<RowDefinition Height="20"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20"/>
<ColumnDefinition Width="20"/>
<ColumnDefinition Width="20"/>
<ColumnDefinition Width="20"/>
</Grid.ColumnDefinitions>
<Line Grid.Column="0" Style="{StaticResource verticalLineStyle}"/>
<Line Grid.Column="1" Style="{StaticResource verticalLineStyle}"/>
<Line Grid.Column="2" Style="{StaticResource verticalLineStyle}"/>
<Line Grid.Column="3" Style="{StaticResource verticalLineStyle}"/>
<Line Grid.Row="0" Style="{StaticResource horizontalLineStyle}"/>
<Line Grid.Row="1" Style="{StaticResource horizontalLineStyle}"/>
<Line Grid.Row="2" Style="{StaticResource horizontalLineStyle}"/>
<Line Grid.Row="3" Style="{StaticResource horizontalLineStyle}"/>
Remove trailing whitespace in .gitignore
Also, make sure you have no trailing whitespace in your .gitignore. I got to this question because I was searching for an answer, then I had a funny feeling I should open the editor instead of just cat'ing .gitignore. Removed a single extra space from the end and poof it works now :)
As an alternative to guava
one can use kotlin-stdlib
private Map<String, Choice> nameMap(List<Choice> choices) {
return CollectionsKt.associateBy(choices, Choice::getName);
}
You have one thing to configure. The example is based on GitHub but this shouldn't change the process:
$ git config --global [email protected]:.insteadOf https://github.com/
$ cat ~/.gitconfig
[url "[email protected]:"]
insteadOf = https://github.com/
$ go get github.com/private/repo
For Go modules to work (with Go 1.11 or newer), you'll also need to set the GOPRIVATE
variable, to avoid using the public servers to fetch the code:
export GOPRIVATE=github.com/private/repo
Maybe, you can use moment.js which in my opinion is the best JavaScript library for parsing, formatting and working with dates client-side. You could use something like:
var momentDate = moment('1890-09-30T23:59:59+01:16:20', 'YYYY-MM-DDTHH:mm:ss+-HH:mm:ss');_x000D_
var jsDate = momentDate.toDate();_x000D_
_x000D_
// Now, you can run any JavaScript Date method_x000D_
_x000D_
jsDate.toLocaleString();
_x000D_
The advantage of using a library like moment.js is that your code will work perfectly even in legacy browsers like IE 8+.
Here is the documenation about parsing methods: https://momentjs.com/docs/#/parsing/
This is another solution which I use:
public class CustomAnimator {
private static final String TAG = "com.example.CustomAnimator";
private static Stack<AnimationEntry> animation_stack = new Stack<>();
public static final int DIRECTION_LEFT = 1;
public static final int DIRECTION_RIGHT = -1;
public static final int DIRECTION_UP = 2;
public static final int DIRECTION_DOWN = -2;
static class AnimationEntry {
View in;
View out;
int direction;
long duration;
}
public static boolean hasHistory() {
return !animation_stack.empty();
}
public static void reversePrevious() {
if (!animation_stack.empty()) {
AnimationEntry entry = animation_stack.pop();
slide(entry.out, entry.in, -entry.direction, entry.duration, false);
}
}
public static void clearHistory() {
animation_stack.clear();
}
public static void slide(final View in, View out, final int direction, long duration) {
slide(in, out, direction, duration, true);
}
private static void slide(final View in, final View out, final int direction, final long duration, final boolean save) {
ViewGroup in_parent = (ViewGroup) in.getParent();
ViewGroup out_parent = (ViewGroup) out.getParent();
if (!in_parent.equals(out_parent)) {
return;
}
int parent_width = in_parent.getWidth();
int parent_height = in_parent.getHeight();
ObjectAnimator slide_out;
ObjectAnimator slide_in;
switch (direction) {
case DIRECTION_LEFT:
default:
slide_in = ObjectAnimator.ofFloat(in, "translationX", parent_width, 0);
slide_out = ObjectAnimator.ofFloat(out, "translationX", 0, -out.getWidth());
break;
case DIRECTION_RIGHT:
slide_in = ObjectAnimator.ofFloat(in, "translationX", -out.getWidth(), 0);
slide_out = ObjectAnimator.ofFloat(out, "translationX", 0, parent_width);
break;
case DIRECTION_UP:
slide_in = ObjectAnimator.ofFloat(in, "translationY", parent_height, 0);
slide_out = ObjectAnimator.ofFloat(out, "translationY", 0, -out.getHeight());
break;
case DIRECTION_DOWN:
slide_in = ObjectAnimator.ofFloat(in, "translationY", -out.getHeight(), 0);
slide_out = ObjectAnimator.ofFloat(out, "translationY", 0, parent_height);
break;
}
AnimatorSet animations = new AnimatorSet();
animations.setDuration(duration);
animations.playTogether(slide_in, slide_out);
animations.addListener(new Animator.AnimatorListener() {
@Override
public void onAnimationCancel(Animator arg0) {
}
@Override
public void onAnimationEnd(Animator arg0) {
out.setVisibility(View.INVISIBLE);
if (save) {
AnimationEntry ae = new AnimationEntry();
ae.in = in;
ae.out = out;
ae.direction = direction;
ae.duration = duration;
animation_stack.push(ae);
}
}
@Override
public void onAnimationRepeat(Animator arg0) {
}
@Override
public void onAnimationStart(Animator arg0) {
in.setVisibility(View.VISIBLE);
}
});
animations.start();
}
}
The usage of class. Let's say you have two fragments (list and details fragments)as shown below
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ui_container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="@+id/list_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="@+id/details_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone" />
</FrameLayout>
Usage
View details_container = findViewById(R.id.details_container);
View list_container = findViewById(R.id.list_container);
// You can select the direction left/right/up/down and the duration
CustomAnimator.slide(list_container, details_container,CustomAnimator.DIRECTION_LEFT, 400);
You can use the function CustomAnimator.reversePrevious();
to get the previous view when the user pressed back.
I found those function in UIViewController.h
.
/*
These four methods can be used in a view controller's appearance callbacks to determine if it is being
presented, dismissed, or added or removed as a child view controller. For example, a view controller can
check if it is disappearing because it was dismissed or popped by asking itself in its viewWillDisappear:
method by checking the expression ([self isBeingDismissed] || [self isMovingFromParentViewController]).
*/
- (BOOL)isBeingPresented NS_AVAILABLE_IOS(5_0);
- (BOOL)isBeingDismissed NS_AVAILABLE_IOS(5_0);
- (BOOL)isMovingToParentViewController NS_AVAILABLE_IOS(5_0);
- (BOOL)isMovingFromParentViewController NS_AVAILABLE_IOS(5_0);
Maybe the above functions can detect the ViewController
is appeared or not.
In my case got a working solution through Cross-document Messaging (XDM) and Executing Chrome extension onclick instead of page load.

);
You can also access specific columns and values in each list element with [
and [[
. Here are a couple of examples. First, we can access only the first column of each data frame in the list with lapply(ldf, "[", 1)
, where 1
signifies the column number.
ldf <- list(d1 = d1, d2 = d2) ## create a named list of your data frames
lapply(ldf, "[", 1)
# $d1
# y1
# 1 1
# 2 2
# 3 3
#
# $d2
# y1
# 1 3
# 2 2
# 3 1
Similarly, we can access the first value in the second column with
lapply(ldf, "[", 1, 2)
# $d1
# [1] 4
#
# $d2
# [1] 6
Then we can also access the column values directly, as a vector, with [[
lapply(ldf, "[[", 1)
# $d1
# [1] 1 2 3
#
# $d2
# [1] 3 2 1
ComboBox.SelectionBoxItem.ToString()
Since you've already received help on the query, I'll take a poke at your syntax question:
The first query employs some lesser-known ANSI SQL syntax which allows you to nest joins between the join
and on
clauses. This allows you to scope/tier your joins and probably opens up a host of other evil, arcane things.
Now, while a nested join cannot refer any higher in the join hierarchy than its immediate parent, joins above it or outside of its branch can refer to it... which is precisely what this ugly little guy is doing:
select
count(*)
from Table1 as t1
join Table2 as t2
join Table3 as t3
on t2.Key = t3.Key -- join #1
and t2.Key2 = t3.Key2
on t1.DifferentKey = t3.DifferentKey -- join #2
This looks a little confusing because join #2 is joining t1 to t2 without specifically referencing t2... however, it references t2 indirectly via t3 -as t3 is joined to t2 in join #1. While that may work, you may find the following a bit more (visually) linear and appealing:
select
count(*)
from Table1 as t1
join Table3 as t3
join Table2 as t2
on t2.Key = t3.Key -- join #1
and t2.Key2 = t3.Key2
on t1.DifferentKey = t3.DifferentKey -- join #2
Personally, I've found that nesting in this fashion keeps my statements tidy by outlining each tier of the relationship hierarchy. As a side note, you don't need to specify inner. join is implicitly inner unless explicitly marked otherwise.
For newbies, you can extend your partial service class in a separate cs file and add the code the code provided by "imanabidi" to get it integrated
As others mentioned, you only have doubles in JS. So how do you define a number being an integer? Just check if the rounded number is equal to itself:
function isInteger(f) {
return typeof(f)==="number" && Math.round(f) == f;
}
function isFloat(f) { return typeof(f)==="number" && !isInteger(f); }
I would recommend setting AutoEllipsis
property of label to true
and AutoSize
to false
. If text length exceeds label bounds, it'll add three dots (...)
at the end and automatically set the complete text as a tooltip. So users can see the complete text by hovering over the label.
A simple program shows how to use for loop to find sum of serveral integers.
#include <iostream>
using namespace std;
int main ()
{
int sum = 0;
int endnum = 2;
for(int i = 0; i<=endnum; i++){
sum += i;
}
cout<<sum;
}
It's simple:
Edit ~/.profile and put your variables as follow
$ vim ~/.profile
In file put:
MY_ENV_VAR=value
Save ( :wq )
Restart the terminal (Quit and open it again)
Make sure that`s all be fine:
$ echo $MY_ENV_VAR
$ value
Read Initial password :
C:\Program Files(x86)\Jenkins\secrets\initialAdminPassword
Default username is 'admin' and the password is the one from initialAdminPassword when you follow the above path.
'Manage Jenkins' --> 'Manage Users' --> Password
Then logout and login to make sure new password works.
This should work for you. If you are using SPA.
app.use('/', express.static(path.join(__dirname, 'your folder')));
// Send all other requests to the SPA
app.get('*', (req, res) => {
res.sendFile(path.join(__dirname, 'your folder/index.html'));
});
string.Format("{0:yyyy-MM-ddTHH:mm:ss.FFFZ}", DateTime.UtcNow)
returns 2017-02-10T08:12:39.483Z
I come across similar problem while calling stored procedure

As far as I'm aware Ratchet is the best PHP WebSocket solution available at the moment. And since it's open source you can see how the author has built this WebSocket solution using PHP.
I ran into the same problem. From my solution i came into this. So here is your code:
- root_directory
- sub_directory_a
- _common.scss
- template.scss
- sub_directory_b
- more_styles.scss
As far i know if you want to import one scss to another its has to be a partial. When you are importing from different directory name your more_styles.scss
to _more_styles.scss
. Then import it into your template.scss
like this @import ../sub_directory_b/_more_styles.scss
. It worked for me. But as you mentioned ../sub_directory_a/_common.scss
not working. That's the same directory of the template.scss
. That is why it wont work.
As mentioned by Blauhirn after 2.7 pip is preinstalled. If it is not working for you it might need to be added to path.
However if you run Windows 10 you no longer have to open a terminal to install a module. The same goes for opening Python as well.
You can type directly into the search menu pip install mechanize
, select command and it will install:
If anything goes wrong however it may close before you can read the error but still it's a useful shortcut.
Just to clarify some of the great answers here, the steps outlined in many of the answers assume that you already have a remote repository somewhere.
Given: an existing git repository, e.g. [email protected]:some-user/full-repo.git
, with one or more directories that you wish to pull independently of the rest of the repo, e.g. directories named app1
and app2
Assuming you have a git repository as the above...
Then: you can run steps like the following to pull only specific directories from that larger repo:
mkdir app1
cd app1
git init
git remote add origin [email protected]:some-user/full-repo.git
git config core.sparsecheckout true
echo "app1/" >> .git/info/sparse-checkout
git pull origin master
I had mistakenly thought that the sparse-checkout options had to be set on the original repository, but this is not the case: you define which directories you want locally, prior to pulling from the remote. The remote repo doesn't know or care about your only wanting to track a part of the repo.
Hope this clarification helps someone else.
Without opening an IDE to check my brain works properly for syntax at this time of day...
If you simply want the date in a particular format you can use DateTime's .ToString(string format). There are a number of examples of standard and custom formatting strings if you follow that link.
So
DateTime _date = DateTime.Now;
var _dateString = _date.ToString("dd/MM/yyyy");
would give you the date as a string in the format you request.
The urls are different.
http://localhost/AccountSvc/DataInquiry.asmx
vs.
/acctinqsvc/portfolioinquiry.asmx
Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.
You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx
, and specify the desired method/operation in the SOAPAction header.
The SOAPAction header values are different.
http://localhost/AccountSvc/DataInquiry.asmx/ + methodName
vs.
http://tempuri.org/GetMyName
You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl
There should be a <soap:operation>
tag underneath the <wsdl:operation>
tag that matches the operation you are attempting to execute, which appears to be GetMyName
.
There is no XML declaration in the request body that includes your SOAP XML.
You specify text/xml
in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii
, but there's no telling if you aren't specifying them!
The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8
Hope that helps!
You can also watch the video about this new featue
UPDATE as of angularjs 1.2, the way animations work has changed drastically, most of it is now controlled with CSS, without having to setup javascript callbacks, etc.. You can check the updated tutorial on Year Of Moo. @dfsq pointed out in the comments a nice set of examples.
Thanks for enlightening us Cypawer.
I also tried this app https://play.google.com/store/apps/details?id=com.oneguyinabasement.leapwifi
and it worked flawlessly.
Finally after a lot of tests, I think the most convenient and efficient way to preset is:
var presetValue = "black";
$("input[name=correctAnswer]").filter("[value=" + presetValue + "]").prop("checked",true);
$("input[name=correctAnswer]").button( "refresh" );//JQuery UI only
The refresh is required with the JQueryUI object.
Retrieving the value is easy :
alert($('input[name=correctAnswer]:checked').val())
Tested with JQuery 1.6.1, JQuery UI 1.8.
Delays can be also implemented by using the following methods.
The first method:
import time
time.sleep(5) # Delay for 5 seconds.
The second method to delay would be using the implicit wait method:
driver.implicitly_wait(5)
The third method is more useful when you have to wait until a particular action is completed or until an element is found:
self.wait.until(EC.presence_of_element_located((By.ID, 'UserName'))
PostgreSQL also supports full POSIX regular expressions:
select * from table where value ~* 'foo|bar|baz';
The ~*
is for a case insensitive match, ~
is case sensitive.
Another option is to use ANY:
select * from table where value like any (array['%foo%', '%bar%', '%baz%']);
select * from table where value ilike any (array['%foo%', '%bar%', '%baz%']);
You can use ANY with any operator that yields a boolean. I suspect that the regex options would be quicker but ANY is a useful tool to have in your toolbox.
If you’re not averse to using double-dollar scope props and you’re writing a directive whose only content is a repeat, there is a pretty simple solution (assuming you only care about the initial render). In the link function:
const dereg = scope.$watch('$$childTail.$last', last => {
if (last) {
dereg();
// do yr stuff -- you may still need a $timeout here
}
});
This is useful for cases where you have a directive that needs to do DOM manip based on the widths or heights of the members of a rendered list (which I think is the most likely reason one would ask this question), but it’s not as generic as the other solutions that have been proposed.
If you add the android:theme="@style/Theme.AppCompat.Light"
to <application>
in AndroidManifest.xml file, problem is solving.
You can write a function that launches and tests the command for you. Assume command1
and command2
are environment variables that have been set to a command.
function mytest {
"$@"
local status=$?
if (( status != 0 )); then
echo "error with $1" >&2
fi
return $status
}
mytest "$command1"
mytest "$command2"
__new__
is static class method, while __init__
is instance method.
__new__
has to create the instance first, so __init__
can initialize it. Note that __init__
takes self
as parameter. Until you create instance there is no self
.
Now, I gather, that you're trying to implement singleton pattern in Python. There are a few ways to do that.
Also, as of Python 2.6, you can use class decorators.
def singleton(cls):
instances = {}
def getinstance():
if cls not in instances:
instances[cls] = cls()
return instances[cls]
return getinstance
@singleton
class MyClass:

Try this (edited):
ctx.Database.ExecuteSqlCommand(sql, new SqlParameter("FirstName", firstName),
new SqlParameter("Id", id));
Previous idea was wrong.
I had to catch all three events related to pressing keys in order to prevent the form from being submitted:
var preventSubmit = function(event) {
if(event.keyCode == 13) {
console.log("caught ya!");
event.preventDefault();
//event.stopPropagation();
return false;
}
}
$("#search").keypress(preventSubmit);
$("#search").keydown(preventSubmit);
$("#search").keyup(preventSubmit);
You can combine all the above into a nice compact version:
$('#search').bind('keypress keydown keyup', function(e){
if(e.keyCode == 13) { e.preventDefault(); }
});
You can use like this, it works!
WebProxy proxy = new WebProxy
{
Address = new Uri(""),
Credentials = new NetworkCredential("", "")
};
HttpClientHandler httpClientHandler = new HttpClientHandler
{
Proxy = proxy,
UseProxy = true
};
HttpClient client = new HttpClient(httpClientHandler);
HttpResponseMessage response = await client.PostAsync("...");
from random import randrange
from datetime import timedelta
def random_date(start, end):
"""
This function will return a random datetime between two datetime
objects.
"""
delta = end - start
int_delta = (delta.days * 24 * 60 * 60) + delta.seconds
random_second = randrange(int_delta)
return start + timedelta(seconds=random_second)
The precision is seconds. You can increase precision up to microseconds, or decrease to, say, half-hours, if you want. For that just change the last line's calculation.
example run:
from datetime import datetime
d1 = datetime.strptime('1/1/2008 1:30 PM', '%m/%d/%Y %I:%M %p')
d2 = datetime.strptime('1/1/2009 4:50 AM', '%m/%d/%Y %I:%M %p')
print(random_date(d1, d2))
output:
2008-12-04 01:50:17
try this trick
div{
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
this will force the browser to calculate the width acording to the "outer"-width of the div, it means the padding will be substracted from the width.
I can come up with 2 ways to achieve it.
The first one is to remove novalidate
to enable the browser's validation.
Second, you can disable the save
button when the form is not valid like this
<input ng-disabled="!frmRegister.$valid" type="submit" value="Save" />
Hope it helps.
Macs have a builtin /usr/bin/pg_dump
command that is used as default.
With the postgresql install you get another binary at /Library/PostgreSQL/<version>/bin/pg_dump
Logger log = Logger.getLogger("myApp");
log.setLevel(Level.ALL);
log.info("initializing - trying to load configuration file ...");
//Properties preferences = new Properties();
try {
//FileInputStream configFile = new //FileInputStream("/path/to/app.properties");
//preferences.load(configFile);
InputStream configFile = myApp.class.getResourceAsStream("app.properties");
LogManager.getLogManager().readConfiguration(configFile);
} catch (IOException ex)
{
System.out.println("WARNING: Could not open configuration file");
System.out.println("WARNING: Logging not configured (console output only)");
}
log.info("starting myApp");
this is working..:) you have to pass InputStream in readConfiguration().
You should do a one-time setup of creating an "App password" in Bitbucket web UI with permissions to at least read your repositories and then use it in the command line.
How-to:
Firstly, why doesn't your solution work. You mix up a lot of concepts. Mostly character class with other ones. In the first character class you use |
which stems from alternation. In character classes you don't need the pipe. Just list all characters (and character ranges) you want:
[Uu]
Or simply write u
if you use the case-insensitive modifier. If you write a pipe there, the character class will actually match pipes in your subject string.
Now in the second character class you use the comma to separate your characters for some odd reason. That does also nothing but include commas into the matchable characters. s
and W
are probably supposed to be the built-in character classes. Then escape them! Otherwise they will just match literal s
and literal W
. But then \W
already includes everything else you listed there, so a \W
alone (without square brackets) would have been enough. And the last part (^a-zA-Z)
also doesn't work, because it will simply include ^
, (
, )
and all letters into the character class. The negation syntax only works for entire character classes like [^a-zA-Z]
.
What you actually want is to assert that there is no letter in front or after your u
. You can use lookarounds for that. The advantage is that they won't be included in the match and thus won't be removed:
r'(?<![a-zA-Z])[uU](?![a-zA-Z])'
Note that I used a raw string. Is generally good practice for regular expressions, to avoid problems with escape sequences.
These are negative lookarounds that make sure that there is no letter character before or after your u
. This is an important difference to asserting that there is a non-letter character around (which is similar to what you did), because the latter approach won't work at the beginning or end of the string.
Of course, you can remove the spaces around you
from the replacement string.
If you don't want to replace u
that are next to digits, you can easily include the digits into the character classes:
r'(?<![a-zA-Z0-9])[uU](?![a-zA-Z0-9])'
And if for some reason an adjacent underscore would also disqualify your u
for replacement, you could include that as well. But then the character class coincides with the built-in \w
:
r'(?<!\w)[uU](?!\w)'
Which is, in this case, equivalent to EarlGray's r'\b[uU]\b'
.
As mentioned above you can shorten all of these, by using the case-insensitive modifier. Taking the first expression as an example:
re.sub(r'(?<![a-z])u(?![a-z])', 'you', text, flags=re.I)
or
re.sub(r'(?<![a-z])u(?![a-z])', 'you', text, flags=re.IGNORECASE)
depending on your preference.
I suggest that you do some reading through the tutorial I linked several times in this answer. The explanations are very comprehensive and should give you a good headstart on regular expressions, which you will probably encounter again sooner or later.
You can't update more that one table in a single statement, however the error message you get is because of the aliases, you could try this :
BEGIN TRANSACTION
update A
set A.ORG_NAME = @ORG_NAME
from table1 A inner join table2 B
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID
update B
set B.REF_NAME = @REF_NAME
from table2 B inner join table1 A
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID
COMMIT
Use .col instead of col-lg-3 :
<div class="row">
<div class="col">
Fixed content
</div>
<div class="col-lg-9">
Normal scrollable content
</div>
</div>
Your destructor might be executing inside a chain of other destructors. Throwing an exception that is not caught by your immediate caller can leave multiple objects in an inconsistent state, thus causing even more problems then ignoring the error in the cleanup operation.
If you want to add a scroll bar using jquery the following will work. If your div had a id of 'mydiv' you could us the following jquery id selector with css property:
jQuery('#mydiv').css("overflow-y", "scroll");
window.location.href = "URL2"
inside a JS block on the page or in an included file; that's assuming you really want to do it on the client. Usually, the server sends the redirect via a 300-series response.
Using collections.defaultdict
is a big time-saver when you're building dicts and don't know beforehand which keys you're going to have.
Here it's used twice: for the resulting dict, and for each of the values in the dict.
import collections
def aggregate_names(errors):
result = collections.defaultdict(lambda: collections.defaultdict(list))
for real_name, false_name, location in errors:
result[real_name][false_name].append(location)
return result
Combining this with your code:
dictionary = aggregate_names(previousFunction(string))
Or to test:
EXAMPLES = [
('Fred', 'Frad', 123),
('Jim', 'Jam', 100),
('Fred', 'Frod', 200),
('Fred', 'Frad', 300)]
print aggregate_names(EXAMPLES)
If you're working under your feature and don't want to checkout back to master, you can run:
cd ./myrepo
git worktree add ../myrepo_master master
git worktree remove ../myrepo_master
It will create ../myrepo_master
directory with master
branch commits, where you can continue work
setSize()
or setBounds()
can be used when no layout manager is being used.
However, if you are using a layout manager you can provide hints to the layout manager using the setXXXSize()
methods like setPreferredSize()
and setMinimumSize()
etc.
And be sure that the component's container uses a layout manager that respects the requested size. The FlowLayout
, GridBagLayout
, and SpringLayout
managers use the component's preferred size (the latter two depending on the constraints you set), but BorderLayout
and GridLayout
usually don't.If you specify new size hints for a component that's already visible, you need to invoke the revalidate method on it to make sure that its containment hierarchy is laid out again. Then invoke the repaint method.
DELETE FROM deadline where ID IN (
SELECT d.ID FROM `deadline` d LEFT JOIN `job` ON deadline.job_id = job.job_id WHERE `status` = 'szamlazva' OR `status` = 'szamlazhato' OR `status` = 'fizetve' OR `status` = 'szallitva' OR `status` = 'storno');
I am not sure if that kind of sub query works in MySQL, but try it. I am assuming you have an ID column in your deadline table.
Open your php.ini file (If you are using Linux - sudo vim /etc/php5/apache2/php.ini)
Add this lines into that file
error_reporting = E_ALL & ~E_WARNING
(If you need to disabled any other errors -> error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_NOTICE & ~E_WARNING)
display_errors = On
And finally you need to restart your APACHE server.
It is not quite as baked-in in Java, so you don't get this for free. It is done with convention rather than language constructs. In all data transfer classes (and maybe even in all classes you write...), you should implement a sensible toString
method. So here you need to override toString()
in your Person
class and return the desired state.
There are utilities available that help with writing a good toString method, or most IDEs have an automatic toString()
writing shortcut.
The StartsWith method will be faster, as there is no overhead of interpreting a regular expression, but here is how you do it:
if (Regex.IsMatch(theString, "^(mailto|ftp|joe):")) ...
The ^
mathes the start of the string. You can put any protocols between the parentheses separated by |
characters.
Another approach that is much faster, is to get the start of the string and use in a switch. The switch sets up a hash table with the strings, so it's faster than comparing all the strings:
int index = theString.IndexOf(':');
if (index != -1) {
switch (theString.Substring(0, index)) {
case "mailto":
case "ftp":
case "joe":
// do something
break;
}
}
I assume you are using gcc
, to simply link object files do:
$ gcc -o output file1.o file2.o
To get the object-files simply compile using
$ gcc -c file1.c
this yields file1.o and so on.
If you want to link your files to an executable do
$ gcc -o output file1.c file2.c
can be two reason
You can also delegate:
class Company < ActiveRecord::Base
has_many :employees
has_many :dogs, :through => :employees
end
class Employee < ActiveRescord::Base
belongs_to :company
has_many :dogs
end
class Dog < ActiveRecord::Base
belongs_to :employee
delegate :company, :to => :employee, :allow_nil => true
end
Based on your desire that 1317427200
be the output, there are several layers of issue to address.
First as others have mentioned, java already uses a UTC 1/1/1970 epoch. There is normally no need to calculate the epoch and perform subtraction unless you have weird locale rules.
Second, when you create a new Calendar it's initialized to 'now' so it includes the time of day. Changing the year/month/day doesn't affect the time of day fields. So if you want it to represent midnight of the date, you need to zero out the calendar before you set the date.
Third, you haven't specified how you're supposed to handle time zones. Daylight Savings can cause differences in the absolute number of seconds represented by a particular calendar-on-the-wall-date, depending on where your JVM is running. Since epoch is in UTC, we probably want to work in UTC times? You may need to seek clarification from the makers of the system you're interfacing with.
Fourth, months in Java are zero indexed. January is 0, October is 9.
Putting all that together
Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
calendar.clear();
calendar.set(2011, Calendar.OCTOBER, 1);
long secondsSinceEpoch = calendar.getTimeInMillis() / 1000L;
that will give you 1317427200
Check out if you are missing some import.
So, as was mentioned in a couple comments containing the data in an array is simpler but the solution does not scale well in terms of efficiency as the data set size increases. You really should only use an iterator when you want to access a random object in the array, otherwise, generators are the way to go. Below I have prototyped a reader function which reads each json object individually and returns a generator.
The basic idea is to signal the reader to split on the carriage character "\n"
(or "\r\n"
for Windows). Python can do this with the file.readline()
function.
import json
def json_reader(filename):
with open(filename) as f:
for line in f:
yield json.loads(line)
However, this method only really works when the file is written as you have it -- with each object separated by a newline character. Below I wrote an example of a writer that separates an array of json objects and saves each one on a new line.
def json_writer(file, json_objects):
with open(file, "w") as f:
for jsonobj in json_objects:
jsonstr = json.dumps(jsonobj)
f.write(jsonstr + "\n")
You could also do the same operation with file.writelines()
and a list comprehension:
...
json_strs = [json.dumps(j) + "\n" for j in json_objects]
f.writelines(json_strs)
...
And if you wanted to append the data instead of writing a new file just change open(file, "w")
to open(file, "a")
.
In the end I find this helps a great deal not only with readability when I try and open json files in a text editor but also in terms of using memory more efficiently.
On that note if you change your mind at some point and you want a list out of the reader, Python allows you to put a generator function inside of a list and populate the list automatically. In other words, just write
lst = list(json_reader(file))
Pretty easy to do this across multiple cells, without having to add '%' to each individually.
Select all the cells you want to change to percent, right Click, then format Cells, choose Custom. Type in 0.0\%
.
I also have a site that has numerous urls with urlencoded characters. I am finding that many web APIs (including Google webmaster tools and several Drupal modules) trip over urlencoded characters. Many APIs automatically decode urls at some point in their process and then use the result as a URL or HTML. When I find one of these problems, I usually double encode the results (which turns %2f into %252f) for that API. However, this will break other APIs which are not expecting double encoding, so this is not a universal solution.
Personally I am getting rid of as many special characters in my URLs as possible.
Also, I am using id numbers in my URLs which do not depend on urldecoding:
example.com/blog/my-amazing-blog%2fstory/yesterday
becomes:
example.com/blog/12354/my-amazing-blog%2fstory/yesterday
in this case, my code only uses 12354 to look for the article, and the rest of the URL gets ignored by my system (but is still used for SEO.) Also, this number should appear BEFORE the unused URL components. that way, the url will still work, even if the %2f gets decoded incorrectly.
Also, be sure to use canonical tags to ensure that url mistakes don't translate into duplicate content.
There are two ways for writing a proper media queries in css. If you are writing media queries for larger device first, then the correct way of writing will be:
@media only screen
and (min-width : 415px){
/* Styles */
}
@media only screen
and (min-width : 769px){
/* Styles */
}
@media only screen
and (min-width : 992px){
/* Styles */
}
But if you are writing media queries for smaller device first, then it would be something like:
@media only screen
and (max-width : 991px){
/* Styles */
}
@media only screen
and (max-width : 768px){
/* Styles */
}
@media only screen
and (max-width : 414px){
/* Styles */
}
My naive assumption was that the size of scroll pane will be determined automatically...
The only solution that actually worked for me was explicitly seeting bounds of JScrollPane:
import javax.swing.*;
public class MyFrame extends JFrame {
public MyFrame()
{
setBounds(100, 100, 491, 310);
getContentPane().setLayout(null);
JTextArea textField = new JTextArea();
textField.setEditable(false);
String str = "";
for (int i = 0; i < 50; ++i)
str += "Some text\n";
textField.setText(str);
JScrollPane scroll = new JScrollPane(textField);
scroll.setBounds(10, 11, 455, 249); // <-- THIS
getContentPane().add(scroll);
setLocationRelativeTo ( null );
}
}
Maybe it will help some future visitors :)
Here's a 2020, Reactjs Hook example that I thought could help others. I am using it to add new rows to a Reactjs table. Let me know if I could improve on something.
Adding a new element to a functional state component:
Define the state data:
const [data, setData] = useState([
{ id: 1, name: 'John', age: 16 },
{ id: 2, name: 'Jane', age: 22 },
{ id: 3, name: 'Josh', age: 21 }
]);
Have a button trigger a function to add a new element
<Button
// pass the current state data to the handleAdd function so we can append to it.
onClick={() => handleAdd(data)}>
Add a row
</Button>
function handleAdd(currentData) {
// return last data array element
let lastDataObject = currentTableData[currentTableData.length - 1]
// assign last elements ID to a variable.
let lastID = Object.values(lastDataObject)[0]
// build a new element with a new ID based off the last element in the array
let newDataElement = {
id: lastID + 1,
name: 'Jill',
age: 55,
}
// build a new state object
const newStateData = [...currentData, newDataElement ]
// update the state
setData(newStateData);
// print newly updated state
for (const element of newStateData) {
console.log('New Data: ' + Object.values(element).join(', '))
}
}
If you want to use @OverZealous' answer (https://stackoverflow.com/a/21806974/1019307) in Typescript, you need to import
instead of require
:
import * as debug from 'gulp-debug';
...
return gulp.src('./examples/*.html')
.pipe(debug({title: 'example src:'}))
.pipe(gulp.dest('./build'));
(I also added a title
).
You could use THROW
(available in SQL Server 2012+):
THROW 50000, 'Your custom error message', 1
THROW <error_number>, <message>, <state>
I just wanted to illustrate that the built-in solutions (SQL-only) are not always the best ones. At first I thought that because Django's QuerySet.objects.order_by
method accepts multiple arguments, you could easily chain them:
ordered_authors = Author.objects.order_by('-score', 'last_name')[:30]
But, it does not work as you would expect. Case in point, first is a list of presidents sorted by score (selecting top 5 for easier reading):
>>> auths = Author.objects.order_by('-score')[:5]
>>> for x in auths: print x
...
James Monroe (487)
Ulysses Simpson (474)
Harry Truman (471)
Benjamin Harrison (467)
Gerald Rudolph (464)
Using Alex Martelli's solution which accurately provides the top 5 people sorted by last_name
:
>>> for x in sorted(auths, key=operator.attrgetter('last_name')): print x
...
Benjamin Harrison (467)
James Monroe (487)
Gerald Rudolph (464)
Ulysses Simpson (474)
Harry Truman (471)
And now the combined order_by
call:
>>> myauths = Author.objects.order_by('-score', 'last_name')[:5]
>>> for x in myauths: print x
...
James Monroe (487)
Ulysses Simpson (474)
Harry Truman (471)
Benjamin Harrison (467)
Gerald Rudolph (464)
As you can see it is the same result as the first one, meaning it doesn't work as you would expect.
the following code works for me in Mozilla and Chrome.
Its log function that shows the file's name and the line of the caller.
log: function (arg) {
var toPrint = [];
for (var i = 0; i < arguments.length; ++i) {
toPrint.push(arguments[i]);
}
function getErrorObject(){
try { throw Error('') } catch(err) { return err; }
}
var err = getErrorObject(),
caller;
if ($.browser.mozilla) {
caller = err.stack.split("\n")[2];
} else {
caller = err.stack.split("\n")[4];
}
var index = caller.indexOf('.js');
var str = caller.substr(0, index + 3);
index = str.lastIndexOf('/');
str = str.substr(index + 1, str.length);
var info = "\t\tFile: " + str;
if ($.browser.mozilla) {
str = caller;
} else {
index = caller.lastIndexOf(':');
str = caller.substr(0, index);
}
index = str.lastIndexOf(':');
str = str.substr(index + 1, str.length);
info += " Line: " + str;
toPrint.push(info);
console.log.apply(console, toPrint);
}
You have to initialise the object (create the object itself) in order to be able to call its methods otherwise you would get a NullPointerException
.
WordList words = new WordList();
I'd probably change your example to look like this:
<ul ng-repeat="task in tasks">
<li ng-mouseover="enableEdit(task)" ng-mouseleave="disableEdit(task)">{{task.name}}</li>
<span ng-show="task.editable"><a>Edit</a></span>
</ul>
//js
$scope.enableEdit = function(item){
item.editable = true;
};
$scope.disableEdit = function(item){
item.editable = false;
};
I know it's a subtle difference, but makes the domain a little less bound to UI actions. Mentally it makes it easier to think about an item being editable rather than having been moused over.
Example jsFiddle.
A common trick is to check like this:
trim(TextBox1.Value & vbnullstring) = vbnullstring
this will work for spaces, empty strings, and genuine null values
You might consider using double slashes on your directory e.g

SqlCommand cmd = new SqlCommand("spInsertCustomerData",Con);
// 2. set the command object so it knows to execute a stored procedure
cmd.CommandType = CommandType.StoredProcedure;

I found this question by the title. If anyone else is looking for the answer on how to just get the domain name, use the following environment variable.
System.Environment.UserDomainName
I'm aware that the author to the question mentions this, but I missed it at the first glance and thought someone else might do the same.
What the description of the question then ask for is the fully qualified domain name (FQDN).
With Internet Explorer you often have to specify the Pragma: public header as well for the download to function properly..
header('Pragma: public');
Just my 2 cents..
What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.
I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

Since I went on about it in the comments for @Rocket's answer, I may as well provide an example that uses no libraries. This requires two new prototype functions, contains
and unique

Array.prototype.unique = function() {_x000D_
var arr = [];_x000D_
for (var i = 0; i < this.length; i++) {_x000D_
if (!arr.contains(this[i])) {_x000D_
arr.push(this[i]);_x000D_
}_x000D_

var duplicates = [1, 3, 4, 2, 1, 2, 3, 8];_x000D_
var uniques = duplicates.unique(); // result = [1,3,4,2,8]_x000D_
_x000D_
console.log(uniques);
_x000D_
For more reliability, you can replace contains
with MDN's indexOf
shim and check if each element's indexOf
is equal to -1: documentation
Remove the visible="false" attribute and add a CSS class that is not visible by default. Then you should be able to reference the dropdown by the correct id, for example:

ActiveRecord 4.0 and above adds where.not
so you can do this:
Foo.includes(:bar).where.not('bars.id' => nil)
Foo.includes(:bar).where.not(bars: { id: nil })
When working with scopes between tables, I prefer to leverage merge
so that I can use existing scopes more easily.
Foo.includes(:bar).merge(Bar.where.not(id: nil))
Also, since includes
does not always choose a join strategy, you should use references
here as well, otherwise you may end up with invalid SQL.
Foo.includes(:bar)
.references(:bar)
.merge(Bar.where.not(id: nil))
First, your code does not contain a contact
div, it has a contacts
div!
In sidebar you have contact
in the div at the bottom of the page you have contacts
. I removed the final s
for the code sample. (you also misspelled the projectslink
id in the sidebar).
Second, take a look at some of the examples for click on the jQuery reference page. You have to use click like, object.click( function() { // Your code here } );
in order to bind a click event handler to the object.... Like in my example below. As an aside, you can also just trigger a click on an object by using it without arguments, like object.click()
.
Third, scrollTo
is a plugin in jQuery. I don't know if you have the plugin installed. You can't use scrollTo()
without the plugin. In this case, the functionality you desire is only 2 lines of code, so I see no reason to use the plugin.
Ok, now on to a solution.
The code below will scroll to the correct div if you click a link in the sidebar. The window does have to be big enough to allow scrolling:
// This is a functions that scrolls to #{blah}link
function goToByScroll(id) {
// Remove "link" from the ID
id = id.replace("link", "");
// Scroll
$('html,body').animate({
scrollTop: $("#" + id).offset().top
}, 'slow');
}
$("#sidebar > ul > li > a").click(function(e) {
// Prevent a page reload when a link is pressed
e.preventDefault();
// Call the scroll function
goToByScroll(this.id);
});
( Scroll to function taken from here )
PS: Obviously you should have a compelling reason to go this route instead of using anchor tags <a href="#gohere">blah</a>
... <a name="gohere">blah title</a>
I'm so surprised no one has mentioned the standard way in Posix
Please use basename / dirname
constructs.
man basename
You could simplify the above equations using the following:
boolean flag = sqlInt != 0;
If the int representation (sqlInt) of the boolean is 0 (false), the boolean (flag) will be false, otherwise it will be true.
Concise code is always nicer to work with :)
One simple example for return SQL table as formatted JSON and fix error as he had @Whitecat
I get the error datetime.datetime(1941, 10, 31, 0, 0) is not JSON serializable
In that example you should use JSONEncoder.
import json
import pymssql
# subclass JSONEncoder
class DateTimeEncoder(JSONEncoder):
#Override the default method
def default(self, obj):
if isinstance(obj, (datetime.date, datetime.datetime)):
return obj.isoformat()
def mssql_connection():
try:
return pymssql.connect(server="IP.COM", user="USERNAME", password="PASSWORD", database="DATABASE")
except Exception:
print("\nERROR: Unable to connect to the server.")
exit(-1)
def query_db(query):
cur = mssql_connection().cursor()
cur.execute(query)
r = [dict((cur.description[i][0], value) for i, value in enumerate(row)) for row in cur.fetchall()]
cur.connection.close()
return r
def write_json(query_path):
# read sql from file
with open("../sql/my_sql.txt", 'r') as f:
sql = f.read().replace('\n', ' ')
# creating and writing to a json file and Encode DateTime Object into JSON using custom JSONEncoder
with open("../output/my_json.json", 'w', encoding='utf-8') as f:
json.dump(query_db(sql), f, ensure_ascii=False, indent=4, cls=DateTimeEncoder)
if __name__ == "__main__":
write_json()
# You get formatted my_json.json, for example:
[
{
"divroad":"N",
"featcat":null,
"countyfp":"001",
"date":"2020-08-28"
}
]
A simpler scan would be:
String1.scan(/<(\S+)>/).last

With Spark 2.0, following is how you can read CSV
val conf = new SparkConf().setMaster("local[2]").setAppName("my app")
val sc = new SparkContext(conf)
val sparkSession = SparkSession.builder
.config(conf = conf)
.appName("spark session example")
.getOrCreate()
val path = "/Users/xxx/Downloads/usermsg.csv"
val base_df = sparkSession.read.option("header","true").
csv(path)
I think this is along the lines of what you're looking for. It appears that you want to see the orderid, the subtotal for each item in the order and the total amount for the order.
select o1.orderID, o1.subtotal, sum(o2.UnitPrice * o2.Quantity) as order_total from
(
select o.orderID, o.price * o.qty as subtotal
from product p inner join orderitem o on p.ProductID= o.productID
where o.orderID = @OrderId
)as o1
inner join orderitem o2 on o1.OrderID = o2.OrderID
group by o1.orderID, o1.subtotal
In my opinion, deferreds/promises (as you have mentionned) is the way to go, rather than using timeouts.
Here is an example I have just written to demonstrate how you could do it using deferreds/promises.
Take some time to play around with deferreds. Once you really understand them, it becomes very easy to perform asynchronous tasks.
Hope this helps!
$(function(){
function1().done(function(){
// function1 is done, we can now call function2
console.log('function1 is done!');
function2().done(function(){
//function2 is done
console.log('function2 is done!');
});
});
});
function function1(){
var dfrd1 = $.Deferred();
var dfrd2= $.Deferred();
setTimeout(function(){
// doing async stuff
console.log('task 1 in function1 is done!');
dfrd1.resolve();
}, 1000);
setTimeout(function(){
// doing more async stuff
console.log('task 2 in function1 is done!');
dfrd2.resolve();
}, 750);
return $.when(dfrd1, dfrd2).done(function(){
console.log('both tasks in function1 are done');
// Both asyncs tasks are done
}).promise();
}
function function2(){
var dfrd1 = $.Deferred();
setTimeout(function(){
// doing async stuff
console.log('task 1 in function2 is done!');
dfrd1.resolve();
}, 2000);
return dfrd1.promise();
}
What you need is properly a service:
.factory('DataLayer', ['$http',
function($http) {
var factory = {};
var locations;
factory.getLocations = function(success) {
if(locations){
success(locations);
return;
}
$http.get('locations/locations.json').success(function(data) {
locations = data;
success(locations);
});
};
return factory;
}
]);
The locations
would be cached in the service which worked as singleton model. This is the right way to fetch data.
Use this service DataLayer
in your controller and directive is ok as following:
appControllers.controller('dummyCtrl', function ($scope, DataLayer) {
DataLayer.getLocations(function(data){
$scope.locations = data;
});
});
.directive('map', function(DataLayer) {
return {
restrict: 'E',
replace: true,
template: '<div></div>',
link: function(scope, element, attrs) {
DataLayer.getLocations(function(data) {
angular.forEach(data, function(location, key){
//do something
});
});
}
};
});
I had also the similar issue in godaddy hosting. But after putting ob_start(); at the beginning of the php page from where page was redirecting, it was working fine.
Please find the example of the fix:
fileName:index.php
<?php
ob_start();
...
header('Location: page1.php');
...
ob_end_flush();
?>
The code says everything:
max@serv$ chmod 777 .
Okay, it doesn't say everything.
In UNIX and Linux, the ability to remove a file is not determined by the access bits of that file. It is determined by the access bits of the directory which contains the file.
Think of it this way -- deleting a file doesn't modify that file. You aren't writing to the file, so why should "w" on the file matter? Deleting a file requires editing the directory that points to the file, so you need "w" on the that directory.
In my small experience:
"=" for Exact Matches.
"LIKE" for Partial Matches.
If you are already loading your own custom CSS file after loading bootstrap.css (version 3) you can add these 2 CSS styles to your custom.css and they will override the bootstrap defaults for the default button style.
.btn-primary:hover, .btn-primary:focus, .btn-primary:active, .btn-primary.active, .open .dropdown-toggle.btn-primary {
background-color: #A6A8C1;
border-color: #31347B;
}
.btn
{
background-color: #9F418F;
border-color: #9F418F;
}
If you use <tbody>
or <tfoot>
in your table, you'll have to use the following syntax or you'll get a incorrect value:
var rowCount = $('#myTable >tbody >tr').length;
@nobar's answer helpfully shows how to use tab completion to list a makefile's targets.
This works great for platforms that provide this functionality by default (e.g., Debian, Fedora).
On other platforms (e.g., Ubuntu) you must explicitly load this functionality, as implied by @hek2mgl's answer:
. /etc/bash_completion
installs several tab-completion functions, including the one for make
make
:
. /usr/share/bash-completion/completions/make
_complete_make() { COMPREPLY=($(compgen -W "$(make -pRrq : 2>/dev/null | awk -v RS= -F: '/^# File/,/^# Finished Make data base/ {if ($1 !~ "^[#.]") {print $1}}' | egrep -v '^[^[:alnum:]]' | sort | xargs)" -- "${COMP_WORDS[$COMP_CWORD]}")); }
complete -F _complete_make make
-f <file>
.Better yet use JScience as BigDecimal is fairly limited (e.g., no sqrt function)
double dCommission = 1586.6 - 708.75;
System.out.println(dCommission);
> 877.8499999999999
Real dCommissionR = Real.valueOf(1586.6 - 708.75);
System.out.println(dCommissionR);
> 877.850000000000
your validation should be occur before your event suppose you are going to submit your form.
anyway if you want this on onchange, so here is code.
function valid(id)
{
var textVal=document.getElementById(id).value;
if (!textVal.match(/\S/))
{
alert("Field is blank");
return false;
}
else
{
return true;
}
}
Alternatively, create a figure()
object using the figsize
argument and then use add_subplot
to add your subplots. E.g.
import matplotlib.pyplot as plt
import numpy as np
f = plt.figure(figsize=(10,3))
ax = f.add_subplot(121)
ax2 = f.add_subplot(122)
x = np.linspace(0,4,1000)
ax.plot(x, np.sin(x))
ax2.plot(x, np.cos(x), 'r:')
Benefits of this method are that the syntax is closer to calls of subplot()
instead of subplots()
. E.g. subplots doesn't seem to support using a GridSpec
for controlling the spacing of the subplots, but both subplot()
and add_subplot()
do.
You're not running a module -- you're running subroutines/functions that happen to be stored in modules.
If you put the code in a standalone module and don't specify scope in the definitions of your subroutines/functions, they will be public by default, and callable from anywhere within your application. This means that you can call them with RunCode in a macro, from the class modules of forms/reports, from standalone class modules, or for the functions, from SQL (with some caveats).
Given that you were trying to implement in VBA something that you felt was too complicated for SQL, SQL is the likely context in which you want to execute the code. So, you should just be able to call your function within the SQL statement:
SELECT MyTable.PersonID, MyTable.FirstName, MyTable.LastName, FormatAddress([Address], [City], [State], [Zip], [Country]) As Address
FROM MyTable;
That SQL calls a public function called FormatAddress() that takes as arguments the components of an address and formats them appropriately. It's a trivial example as you likely would not need a VBA function for that purpose, but the point is that this is how you call functions from within a SQL statement.
Subroutines (i.e., code that returns no value) are not callable from within SQL statements.
If you want to upload a folder or a file to Github
1- Create a repository on the Github
2- make: git remote add origin "Your Link" as it is described on the Github
3- Then use git push -u origin master.
4- You have to enter your username and Password.
5- After the authentication, the transfer will start
I believe this will solve the issue
var z = '[{"name":"1","age":"2"},{"name":"1","age":"3"}]';
z = JSON.stringify(JSON.parse(z));
$.ajax({
url: "/setTest",
data: z,
type: "POST",
dataType:"json",
contentType:'application/json'
});
// Month here is 1-indexed (January is 1, February is 2, etc). This is
// because we're using 0 as the day so that it returns the last day
// of the last month, so you have to add 1 to the month number
// so it returns the correct amount of days
function daysInMonth (month, year) {
return new Date(year, month, 0).getDate();
}
// July
daysInMonth(7,2009); // 31
// February
daysInMonth(2,2009); // 28
daysInMonth(2,2008); // 29
And there exists no reliable function for it. Consider for example this filename:
archive.tar.gz
What is the extension? DOS users would have preferred the name archive.tgz
. Sometimes you see stupid Windows applications that first decompress the file (yielding a .tar
file), then you have to open it again to see the archive contents.
In this case, a more reasonable notion of file extension would have been .tar.gz
. There are also .tar.bz2
, .tar.xz
, .tar.lz
and .tar.lzma
file "extensions" in use. But how would you decide, whether to split at the last dot, or the second-to-last dot?
The Java 7 function Files.probeContentType will likely be much more reliable to detect file types than trusting the file extension. Pretty much all the Unix/Linux world as well as your Webbrowser and Smartphone already does it this way.
how to club the 4 query's as a single query
show below query
nsc = nature of case
report is taken on 06th of every month
( monthly report will be counted from 05th previous month to 05th present of present month)
In SQL Query, you can write this code:
select table_name from information_schema.tables where table_schema='YOUR_TABLE_SCHEME';
Replace your table scheme with YOUR_TABLE_SCHEME;
Example:
select table_name from information_schema.tables where table_schema='eLearningProject';
To see all scheme and all tables, there is no need of where clause:
select table_name from information_schema.tables
Out of interest, this flags up one of R's weird multiple syntax inconsistencies. For example given a two-column data frame:
df <- data.frame(x=1, y=2)
This gives a data frame
subset(df, select=-y)
but this gives a vector
df[,-2]
This is all explained in ?[
but it's not exactly expected behaviour. Well at least not to me...

If the coding standards for the particular codebase I am writing code for specifies which operator should be used, I'll definitely use that. If not, and the code dictates which should be used (not often, can be easily worked around) then I'll use that. Otherwise, probably &&
.
Is 'and' more readable than '&&'?
Is it more readable to you. The answer is yes and no depending on many factors including the code around the operator and indeed the person reading it!
|| there is ~ difference?
Yes. See logical operators for ||
and bitwise operators for ~
.
If you're using SQL Server 2005 or later (and the tags for your question indicate SQL Server 2008), you can use ranking functions to return the duplicate records after the first one if using joins is less desirable or impractical for some reason. The following example shows this in action, where it also works with null values in the columns examined.
create table Table1 (
Field1 int,
Field2 int,
Field3 int,
Field4 int
)
insert Table1
values (1,1,1,1)
, (1,1,1,2)
, (1,1,1,3)
, (2,2,2,1)
, (3,3,3,1)
, (3,3,3,2)
, (null, null, 2, 1)
, (null, null, 2, 3)
select *
from (select Field1
, Field2
, Field3
, Field4
, row_number() over (partition by Field1
, Field2
, Field3
order by Field4) as occurrence
from Table1) x
where occurrence > 1
Notice after running this example that the first record out of every "group" is excluded, and that records with null values are handled properly.
If you don't have a column available to order the records within a group, you can use the partition-by columns as the order-by columns.
You need to change Java compiler version in in build config.
If you're dealing with a Java character array (such as password characters that you read from the console), you can convert it to a JRuby string with the following Ruby code:
# GIST: "pw_from_console.rb" under "https://gist.github.com/drhuffman12"
jconsole = Java::java.lang.System.console()
password = jconsole.readPassword()
ruby_string = ''
password.to_a.each {|c| ruby_string << c.chr}
# .. do something with 'password' variable ..
puts "password_chars: #{password_chars.inspect}"
puts "password_string: #{password_string}"

By default the grid view will take care, just pass empty data set.
The error says that a warning was treated as an error, therefore your problem is a warning message! The object file is then not created because there was an error. So you need to check your warnings and fix them.
In case you don't know how to find them: Open the Error List
(View
> Error List
) and click on Warning
.

For example folder named new under E: drive
type the command:

e:\new\attrib *.* -s -h /s /d
and all the files and folders are un-hidden
A complete example of how this could be done. To avoid having to write client-side validation scripts, the existing ValidationType = "range" has been used.
public class MinValueAttribute : ValidationAttribute, IClientValidatable
{
private readonly double _minValue;
public MinValueAttribute(double minValue)
{
_minValue = minValue;
ErrorMessage = "Enter a value greater than or equal to " + _minValue;
}
public MinValueAttribute(int minValue)
{
_minValue = minValue;
ErrorMessage = "Enter a value greater than or equal to " + _minValue;
}
public override bool IsValid(object value)
{
return Convert.ToDouble(value) >= _minValue;
}
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
{
var rule = new ModelClientValidationRule();
rule.ErrorMessage = ErrorMessage;
rule.ValidationParameters.Add("min", _minValue);
rule.ValidationParameters.Add("max", Double.MaxValue);
rule.ValidationType = "range";
yield return rule;
}

Just a small addition to Nick's answer (which works great !) :
If you want to allow spaces in between letters, for example , you may restrict to enter only letters in full name, but it should allow space as well - just list the space as below with a comma. And in the same way if you need to allow any other specific character:
jQuery.validator.addMethod("lettersonly", function(value, element)
{
return this.optional(element) || /^[a-z," "]+$/i.test(value);
}, "Letters and spaces only please");
You have to prepend every directory with -I

I use MacTex, and my editor is TexShop. It probably has to do with what compiler you are using. When I use pdftex, the command:
\includegraphics[height=60mm, width=100mm]{number2.png}
works fine, but when I use "Tex and Ghostscript", I get the same error as you, about not being able to get the size information. Use pdftex.
Incidentally, you can change this in TexShop from the "Typeset" menu.
Hope this helps.
This is how I did it. I don't know why MapRoute() doesn't allow you to set the area, but it does return the route object so you can continue to make any additional changes you would like. I use this because I have a modular MVC site that is sold to enterprise customers and they need to be able to drop dlls into the bin folder to add new modules. I allow them to change the "HomeArea" in the AppSettings config.
var route = routes.MapRoute(
"Home_Default",
"",
new {controller = "Home", action = "index" },
new[] { "IPC.Web.Core.Controllers" }
);
route.DataTokens["area"] = area;
Edit: You can try this as well in your AreaRegistration.RegisterArea for the area you want the user going to by default. I haven't tested it but AreaRegistrationContext.MapRoute does sets route.DataTokens["area"] = this.AreaName;
for you.
context.MapRoute(
"Home_Default",
"",
new {controller = "Home", action = "index" },
new[] { "IPC.Web.Core.Controllers" }
);
You can use the apply
function of the Series
object:
>>> df = pd.DataFrame([[' a ', 10], [' c ', 5]])
>>> df[0][0]
' a '
>>> df[0] = df[0].apply(lambda x: x.strip())
>>> df[0][0]
'a'
Note the usage of
strip
and not theregex
which is much faster
Another option - use the apply
function of the DataFrame object:
>>> df = pd.DataFrame([[' a ', 10], [' c ', 5]])
>>> df.apply(lambda x: x.apply(lambda y: y.strip() if type(y) == type('') else y), axis=0)
0 1
0 a 10
1 c 5
No, you shouldn't call those methods manually. At the end of the using
block the Dispose()
method is automatically called which will take care to free unmanaged resources (at least for standard .NET BCL classes such as streams, readers/writers, ...). So you could also write your code like this:
using (Stream responseStream = response.GetResponseStream())
using (StreamReader reader = new StreamReader(responseStream))
using (StreamWriter writer = new StreamWriter(filename))
{
int chunkSize = 1024;
while (!reader.EndOfStream)
{
char[] buffer = new char[chunkSize];
int count = reader.Read(buffer, 0, chunkSize);
if (count != 0)
{
writer.Write(buffer, 0, count);
}
}
}
The Close()
method calls Dispose()
.
TL;DR:
socket.send(data, callback)
is essentially equivalent to calling socket.emit('message', JSON.stringify(data), callback)
Without looking at the source code, I would assume that the send function is more efficient edit: for sending string messages, at least?
So yeah basically emit allows you to send objects, which is very handy.
Take this example with socket.emit
:
sendMessage: function(type, message) {
socket.emit('message', {
type: type,
message: message
});
}
and for those keeping score at home, here is what it looks like using socket.send
:
sendMessage: function(type, message) {
socket.send(JSON.stringify({
type: type,
message: message
}));
}
resize()
not only allocates memory, it also creates as many instances as the desired size which you pass to resize()
as argument. But reserve()
only allocates memory, it doesn't create instances. That is,
std::vector<int> v1;
v1.resize(1000); //allocation + instance creation
cout <<(v1.size() == 1000)<< endl; //prints 1
cout <<(v1.capacity()==1000)<< endl; //prints 1
std::vector<int> v2;
v2.reserve(1000); //only allocation
cout <<(v2.size() == 1000)<< endl; //prints 0
cout <<(v2.capacity()==1000)<< endl; //prints 1
Output (online demo):
1
1
0
1
So resize()
may not be desirable, if you don't want the default-created objects. It will be slow as well. Besides, if you push_back()
new elements to it, the size()
of the vector will further increase by allocating new memory (which also means moving the existing elements to the newly allocated memory space). If you have used reserve()
at the start to ensure there is already enough allocated memory, the size()
of the vector will increase when you push_back()
to it, but it will not allocate new memory again until it runs out of the space you reserved for it.
Since you've got an array, what you really want is Array#slice
, not split
.
rest = ex.slice(1 .. -1)
# or
rest = ex[1 .. -1]
Well I guess I have found the solution for my own question, here is how I did it:
Eventhough I was being able to successfully run the program using normal python command as well as successfully run pyinstaller and be able to execute the app "new_app.exe" using the command line mentioned in the question which in both cases display the GUI with no problem at all. However, only when I click the application it won't allow to display the GUI and no error is generated.
So, What I did is I added an extra parameter --debug in the pyinstaller command and removing the --windowed parameter so that I can see what is actually happening when the app is clicked and I found out there was an error which made a lot of sense when I trace it, it basically complained that "some_image.jpg" no such file or directory.
The reason why it complains and didn't complain when I ran the script from the first place or even using the command line "./" is because the file image existed in the same path as the script located but when pyinstaller created "dist" directory which has the app product it makes a perfect sense that the image file is not there and so I basically moved it to that dist directory where the clickable app is there!
For eliminate this error for mismatch sender Id In fcm
{"multicast_id":7751536172966571167,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}
there is error occured,
So we required first, In FCM, register Application e.g MyDemoApplication
After that FCM will generate server key i.e AIzaSyB9krC8mLHzO_TtECb5qg7NDZPxeG03jHU
and sender Id i.e 346252831806
these format like these.
After In Android Studio, our project is connect to these FCM created project i.e MyDemoApplication
And most important step is there required to device token or registration id. These token must created in Android Studio..
After that using Sender Id and API key in web API project u will be definitely getting notification
It'll be good to see the csv file itself, but this might work for you, give it a try, replace:
file_read = csv.reader(self.file)
with:
file_read = csv.reader(self.file, dialect=csv.excel_tab)
Or, open a file with universal newline mode
and pass it to csv.reader
, like:
reader = csv.reader(open(self.file, 'rU'), dialect=csv.excel_tab)
Or, use splitlines()
, like this:
def read_file(self):
with open(self.file, 'r') as f:
data = [row for row in csv.reader(f.read().splitlines())]
return data
I had the same issue -- Finally tried the ? sigil instead of @, and it worked.
According to the docs:
Note. Prior versions of the provider used the '@' symbol to mark parameters in SQL. This is incompatible with MySQL user variables, so the provider now uses the '?' symbol to locate parameters in SQL. To support older code, you can set 'old syntax=yes' on your connection string. If you do this, please be aware that an exception will not be throw if you fail to define a parameter that you intended to use in your SQL.
Really? Why don't you just throw an exception if someone tries to use the so called old syntax? A few hours down the drain for a 20 line program...
You can simply assign it a new value as follows,
window.location.hash
On your backEnd, you should add:
@RequestMapping(value="/blabla", produces="text/plain" , method = RequestMethod.GET)
On the frontEnd (Service):
methodBlabla()
{
const headers = new HttpHeaders().set('Content-Type', 'text/plain; charset=utf-8');
return this.http.get(this.url,{ headers, responseType: 'text'});
}
Add this for pages not currently on your site...
ErrorDocument 404 http://example.com/
Along with your Redirect 301 / http://www.thenewdomain.com/ that should cover all the bases...
Good luck!
i wrote a litte wrapper function on my own...
onResize = function(fn) {
if(!fn || typeof fn != 'function')
return 0;
var args = Array.prototype.slice.call(arguments, 1);
onResize.fnArr = onResize.fnArr || [];
onResize.fnArr.push([fn, args]);
onResize.loop = function() {
$.each(onResize.fnArr, function(index, fnWithArgs) {
fnWithArgs[0].apply(undefined, fnWithArgs[1]);
});
};
$(window).on('resize', function(e) {
window.clearTimeout(onResize.timeout);
onResize.timeout = window.setTimeout("onResize.loop();", 300);
});
};
Here is the usage:
var testFn = function(arg1, arg2) {
console.log('[testFn] arg1: '+arg1);
console.log('[testFn] arg2: '+arg2);
};
// document ready
$(function() {
onResize(testFn, 'argument1', 'argument2');
});
Try this..
If jQuery is available, angular.element is an alias for the jQuery function.
var app = angular.module('myApp',[]);
app.controller('Ctrl', function($scope) {
$scope.click=function(){
angular.element('#div1').addClass("alpha");
};
});
<div id='div1'>Text</div>
<button ng-click="click()">action</button>

.Top = xlApp.ActiveSheet.Cells(i, 20).Top

It's better not to .select anything in Excel, it is usually never necessary and slows down your code.
Here is the simple solution with StreamEx
EntryStream.of(countByType).sortedBy(e -> e.getValue()).keys().toList();
Here is a good example -

padding: 10px 0 10px 20px;
text-indent: -1em;
}

You need to first cast the instance to any
because Function
's type definition does not have a name
property.
class MyClass {
getName() {
return (<any>this).constructor.name;
// OR return (this as any).constructor.name;
}
}
// From outside the class:
var className = (<any>new MyClass()).constructor.name;
// OR var className = (new MyClass() as any).constructor.name;
console.log(className); // Should output "MyClass"
// From inside the class:
var instance = new MyClass();
console.log(instance.getName()); // Should output "MyClass"
With TypeScript 2.4 (and potentially earlier) the code can be even cleaner:
class MyClass {
getName() {
return this.constructor.name;
}
}
// From outside the class:
var className = (new MyClass).constructor.name;
console.log(className); // Should output "MyClass"
// From inside the class:
var instance = new MyClass();
console.log(instance.getName()); // Should output "MyClass"
Java Escape Sequences:
\u{0000-FFFF} /* Unicode [Basic Multilingual Plane only, see below] hex value
does not handle unicode values higher than 0xFFFF (65535),
the high surrogate has to be separate: \uD852\uDF62
Four hex characters only (no variable width) */
\b /* \u0008: backspace (BS) */
\t /* \u0009: horizontal tab (HT) */
\n /* \u000a: linefeed (LF) */
\f /* \u000c: form feed (FF) */
\r /* \u000d: carriage return (CR) */
\" /* \u0022: double quote (") */
\' /* \u0027: single quote (') */
\\ /* \u005c: backslash (\) */
\{0-377} /* \u0000 to \u00ff: from octal value
1 to 3 octal digits (variable width) */
The Basic Multilingual Plane is the unicode values from 0x0000 - 0xFFFF (0 - 65535). Additional planes can only be specified in Java by multiple characters: the egyptian heiroglyph A054 (laying down dude) is U+1303F
/ 𓀿
and would have to be broken into "\uD80C\uDC3F"
(UTF-16) for Java strings. Some other languages support higher planes with "\U0001303F"
.
You can use this in your case, it will work fine.
user = UniversityDetails.objects.filter(email=email).first()
This isn't the cleanest/quickest/easiest/most elegant solution, but it is a brute force one that I created to get the job done in a similar scenario:
DataTable dt = (DataTable)Session["dtAllOrders"];
DataTable dtSpecificOrders = new DataTable();
// Create new DataColumns for dtSpecificOrders that are the same as in "dt"
DataColumn dcID = new DataColumn("ID", typeof(int));
DataColumn dcName = new DataColumn("Name", typeof(string));
dtSpecificOrders.Columns.Add(dtID);
dtSpecificOrders.Columns.Add(dcName);
DataRow[] orderRows = dt.Select("CustomerID = 2");
foreach (DataRow dr in orderRows)
{
DataRow myRow = dtSpecificOrders.NewRow(); // <-- create a brand-new row
myRow[dcID] = int.Parse(dr["ID"]);
myRow[dcName] = dr["Name"].ToString();
dtSpecificOrders.Rows.Add(myRow); // <-- this will add the new row
}
The names in the DataColumns must match those in your original table for it to work. I just used "ID" and "Name" as examples.

The answer is simple: people say ruby is slow because it is slow based on measured comparisons to other languages. Bear in mind, though, "slow" is relative. Often, ruby and other "slow" languages are plenty fast enough.
Create list using C++ templates
i.e
template <class T> struct Node
{
T data;
Node * next;
};
template <class T> class List
{
Node<T> *head,*tail;
public:
void push(T const&); // push element
void pop(); // pop element
bool empty() // return true if empty.
};
Then you can write the code like:
List<MyClass>;
The type T
is not dynamic in run time.It is only for the compile time.
For complete example click here.
For C++ templates tutorial click here.
Readonly will allow the user to copy text from it. Disabled will not.
The problem is in this method:
public static byte[] encrypt(String toEncrypt) throws Exception{
This is the method signature which pretty much says:
In this case the method signature says that when invoked this method "could" potentially throw an exception of type "Exception".
....
concatURL = padString(concatURL, ' ', 16);
byte[] encrypted = encrypt(concatURL); <-- HERE!!!!!
String encryptedString = bytesToHex(encrypted);
content.removeAll();
......
So the compilers is saying: Either you surround that with a try/catch construct or you declare the method ( where is being used ) to throw "Exception" it self.
The real problem is the "encrypt" method definition. No method should ever return "Exception", because it is too generic and may hide some other kinds of exception better is to have an specific exception.
Try this:
public static byte[] encrypt(String toEncrypt) {
try{
String plaintext = toEncrypt;
String key = "01234567890abcde";
String iv = "fedcba9876543210";
SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());
Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");
cipher.init(Cipher.ENCRYPT_MODE,keyspec,ivspec);
byte[] encrypted = cipher.doFinal(toEncrypt.getBytes());
return encrypted;
} catch ( NoSuchAlgorithmException nsae ) {
// What can you do if the algorithm doesn't exists??
// this usually won't happen because you would test
// your code before shipping.
// So in this case is ok to transform to another kind
throw new IllegalStateException( nsae );
} catch ( NoSuchPaddingException nspe ) {
// What can you do when there is no such padding ( whatever that means ) ??
// I guess not much, in either case you won't be able to encrypt the given string
throw new IllegalStateException( nsae );
}
// line 109 won't say it needs a return anymore.
}
Basically in this particular case you should make sure the cryptography package is available in the system.
Java needs an extension for the cryptography package, so, the exceptions are declared as "checked" exceptions. For you to handle when they are not present.
In this small program you cannot do anything if the cryptography package is not available, so you check that at "development" time. If those exceptions are thrown when your program is running is because you did something wrong in "development" thus a RuntimeException subclass is more appropriate.
The last line don't need a return statement anymore, in the first version you were catching the exception and doing nothing with it, that's wrong.
try {
// risky code ...
} catch( Exception e ) {
// a bomb has just exploited
// you should NOT ignore it
}
// The code continues here, but what should it do???

Here are some related answers:
this works too.
df = NULL
for (k in 1:10)
{
x = 1
y = 2
z = 3
df = rbind(df, data.frame(x,y,z))
}
output will look like this
df #enter

You can convert it to a string, and then to an int:
print(int("".join(str(x) for x in [7,7,7,7])))
There is a library which allows you to use HttpClient with strongly-typed callbacks.
The data and the error are available directly via these callbacks.
When you use HttpClient with Observable, you have to use .subscribe(x=>...) in the rest of your code.
This is because Observable<HttpResponse
<T
>> is tied to HttpResponse.
This tightly couples the http layer with the rest of your code.
This library encapsulates the .subscribe(x => ...) part and exposes only the data and error through your Models.
With strongly-typed callbacks, you only have to deal with your Models in the rest of your code.
The library is called angular-extended-http-client.
angular-extended-http-client library on GitHub
angular-extended-http-client library on NPM
Very easy to use.
The strongly-typed callbacks are
Success:
T
>T
>Failure:
TError
>TError
>import { HttpClientExtModule } from 'angular-extended-http-client';
and in the @NgModule imports
imports: [
.
.
.
HttpClientExtModule
],
//Normal response returned by the API.
export class RacingResponse {
result: RacingItem[];
}
//Custom exception thrown by the API.
export class APIException {
className: string;
}
In your Service, you just create params with these callback types.
Then, pass them on to the HttpClientExt's get method.
import { Injectable, Inject } from '@angular/core'
import { RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.
@Injectable()
export class RacingService {
//Inject HttpClientExt component.
constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {
}
//Declare params of type IObservable<T> and IObservableError<TError>.
//These are the success and failure callbacks.
//The success callback will return the response objects returned by the underlying HttpClient call.
//The failure callback will return the error objects returned by the underlying HttpClient call.
getRaceInfo(success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
let url = this.config.apiEndpoint;
this.client.get(url, ResponseType.IObservable, success, ErrorType.IObservableError, failure);
}
}
In your Component, your Service is injected and the getRaceInfo API called as shown below.
ngOnInit() {
this.service.getRaceInfo(response => this.result = response.result,
error => this.errorMsg = error.className);
}
Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.
You only deal with your Models in these strongly-typed callbacks.
Hence, The rest of your code only knows about your Models.
Also, you can still use the traditional route and return Observable<HttpResponse<
T>
> from Service API.
The STL's philosophy is that you choose a container based on guarantees and not based on how the container is implemented. For example, your choice of container may be based on a need for fast lookups. For all you care, the container may be implemented as a unidirectional list -- as long as searching is very fast you'd be happy. That's because you're not touching the internals anyhow, you're using iterators or member functions for the access. Your code is not bound to how the container is implemented but to how fast it is, or whether it has a fixed and defined ordering, or whether it is efficient on space, and so on.
Try this
UPDATE `table` SET `uid` = CASE

WHEN id = 3 THEN 1592
ELSE `uid`
END
WHERE id in (1,2,3)
If you are using jQuery and want to refresh, then try adding your jQuery in a javascript function:
I wanted to hide an iframe from a page when clicking oh an h3
, for me it worked but I wasn't able to click the item that allowed me to view the iframe
to begin with unless I refreshed the browser manually...not ideal.
I tried the following:
var hide = () => {
$("#frame").hide();//jQuery
location.reload(true);//javascript
};
Mixing plain Jane javascript with your jQuery should work.
// code where hide (where location.reload was used)function was integrated, below
iFrameInsert = () => {
var file = `Fe1FVoW0Nt4`;
$("#frame").html(`<iframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/${file}\" frameborder=\"0\" allow=\"autoplay; encrypted-media\" allowfullscreen></iframe><h3>Close Player</h3>`);
$("h3").enter code hereclick(hide);
}
// View Player
$("#id-to-be-clicked").click(iFrameInsert);
The issue is because django is expecting the value from the cookie to be passed back as part of the form data. The code from the previous answer is getting javascript to hunt out the cookie value and put it into the form data. Thats a lovely way of doing it from a technical point of view, but it does look a bit verbose.
In the past, I have done it more simply by getting the javascript to put the token value into the post data.
If you use {% csrf_token %} in your template, you will get a hidden form field emitted that carries the value. But, if you use {{ csrf_token }} you will just get the bare value of the token, so you can use this in javascript like this....
csrf_token = "{{ csrf_token }}";
Then you can include that, with the required key name in the hash you then submit as the data to the ajax call.
You Can use just finish();
everywhere after Activity Start for clear that Activity from Stack.
You're doing it the correct way but users may be providing urls to sites that have invalid SSL certs installed. You can ignore those cert problems if you put this line in before you make the actual web request:

where AcceptAllCertifications
is defined as
public bool AcceptAllCertifications(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certification, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)
{

A recent message box version is the prompt_box module. It has two packages: alert and message. Message gives you greater control over the box, but takes longer to type up.
Example Alert code:
import prompt_box
prompt_box.alert('Hello') #This will output a dialog box with title Neutrino and the
#text you inputted. The buttons will be Yes, No and Cancel
Example Message code:
import prompt_box
prompt_box.message('Hello', 'Neutrino', 'You pressed yes', 'You pressed no', 'You
pressed cancel') #The first two are text and title, and the other three are what is
#printed when you press a certain button
If you set the parent element as position:relative, you can set the child to the bottom setting position:absolute; and bottom:0;
#outer {_x000D_
width:10em;_x000D_
height:10em;_x000D_

I believe it is best to use CharSequence. The reason is that String implements CharSequence, therefore you can pass a String into a CharSequence, HOWEVER you cannot pass a CharSequence into a String, as CharSequence doesn't not implement String. ALSO, in Android the EditText.getText()
method returns an Editable, which also implements CharSequence and can be passed easily into one, while not easily into a String. CharSequence handles all!
func copyToString(r io.Reader) (res string, err error) {
var sb strings.Builder
if _, err = io.Copy(&sb, r); err == nil {
res = sb.String()
}
return
}
You can use a jQuery plugin called Array Utilities to get an array of unique items. It can be done like this:
var distinctArray = $.distinct([1, 2, 2, 3])
distinctArray = [1,2,3]
Yes, Json.Net is what you need. You basically want to deserialize a Json string into an array of objects
.
See their examples:
string myJsonString = @"{
"Name": "Apple",
"Expiry": "\/Date(1230375600000+1300)\/",
"Price": 3.99,
"Sizes": [
"Small",
"Medium",
"Large"
]
}";
// Deserializes the string into a Product object
Product myProduct = JsonConvert.DeserializeObject<Product>(myJsonString);
i had the same issue, my solution:
Before:
CREATE TABLE EMPRES
( NoFilm smallint NOT NULL
PRIMARY KEY (NoFilm)
FOREIGN KEY (NoFilm) REFERENCES cassettes
);
Solution:
CREATE TABLE EMPRES
(NoFilm smallint NOT NULL REFERENCES cassettes,
PRIMARY KEY (NoFilm)
);
I hope it's help ;)
You should check out this plugin:
https://github.com/kemayo/maphilight
and the demo:
http://davidlynch.org/js/maphilight/docs/demo_usa.html
if anything, you might be able to borrow some code from it to fix yours.
Change to the database directory:
cd /var/lib/mysql/
Shut down MySQL... This is important!
/etc/init.d/mysql stop
Okay, this way doesn't work for InnoDB or BDB-Databases.
Rename database:
mv old-name new-name
...or the table...
cd database/
mv old-name.frm new-name.frm
mv old-name.MYD new-name.MYD
mv old-name.MYI new-name.MYI
Restart MySQL
/etc/init.d/mysql start
Done...
OK, this way doesn't work with InnoDB or BDB databases. In this case you have to dump the database and re-import it.
How about checking with python
code:
from tensorflow.python.platform import build_info as tf_build_info
print(tf_build_info.cudnn_version_number)

Use Apache's mod_dumpio. Be careful for obvious reasons.
Note that mod_dumpio stops logging binary payloads at the first null character. For example a multipart/form-data
upload of a gzip'd file will probably only show the first few bytes with mod_dumpio.
Also note that Apache might not mention this module in httpd.conf
even when it's present in the /modules
folder. Just manually adding LoadModule
will work fine.
you're stuck with the
WHERE something LIKE 'bla%'
OR something LIKE '%foo%'
OR something LIKE 'batz%'
unless you populate a temp table (include the wild cards in with the data) and join like this:
FROM YourTable y
INNER JOIN YourTempTable t On y.something LIKE t.something
try it out (using SQL Server syntax):
declare @x table (x varchar(10))
declare @y table (y varchar(10))
insert @x values ('abcdefg')
insert @x values ('abc')
insert @x values ('mnop')
insert @y values ('%abc%')
insert @y values ('%b%')
select distinct *
FROM @x x
WHERE x.x LIKE '%abc%'
or x.x LIKE '%b%'
select distinct x.*
FROM @x x
INNER JOIN @y y On x.x LIKE y.y
OUTPUT:
x
----------
abcdefg
abc
(2 row(s) affected)
x
----------
abc
abcdefg
(2 row(s) affected)
FacebookConnect or OpenID are two great options.
Basically, your users login to other sites they are already members of (Facebook, or Google), and then you get confirmation from that site telling you the user is trustworthy - start a session, and they're logged in. No database needed (unless you want to associate more data to their account).
You can disable a tab in bootstrap 4 by adding class disabled
to the child of nav-item as follows
<li class="nav-item">
<a class="nav-link disabled" data-toggle="tab" href="#messages7" role="tab" aria-expanded="false">
<i class="icofont icofont-ui-message"></i>Home</a>
<div class="slide"></div>
</li>
Best way to do this is to add a data attribute to the field (textbox) where you want to avoid the cut,copy and paste.
Just create a method for the same which is as follows :-
function ignorePaste() {
$("[data-ignorepaste]").bind("cut copy paste", function (e) {
e.preventDefault(); //prevent the default behaviour
});
};
Then once when you add the above code simply add the data attribute to the field where you want to ignore cut copy paste. in our case your add a data attribute to confirm email text box as below :-
Confirm Email: <input type="textbox" id= "confirmEmail" data-ignorepaste=""/>
Call the method ignorePaste()
So in this way you will be able to use this throughout the application, all you need to do is just add the data attribute where you want to ignore cut copy paste
trigger('slideIn', [
state('*', style({ 'overflow-y': 'hidden' })),
state('void', style({ 'overflow-y': 'hidden' })),
transition('* => void', [
style({ height: '*' }),
animate(250, style({ height: 0 }))
]),
transition('void => *', [
style({ height: '0' }),
animate(250, style({ height: '*' }))
])
])
Another alternative.
The OP asked a way to use a callback. In this case he was referring specifically to a function that process an event (in his example: a click event), which shall be treated as the accepted answer from @serginho suggests: with @Output
and EventEmitter
.
However, there is a difference between a callback and an event: With a callback your child component can retrieve some feedback or information from the parent, but an event only can inform that something happened without expect any feedback.
There are use cases where a feedback is necessary, ex. get a color, or a list of elements that the component needs to handle. You can use bound functions as some answers have suggested, or you can use interfaces (that's always my preference).
Example
Let's suppose you have a generic component that operates over a list of elements {id, name} that you want to use with all your database tables that have these fields. This component should:
Child Component
Using normal binding we would need 1 @Input()
and 3 @Output()
parameters (but without any feedback from the parent). Ex. <list-ctrl [items]="list" (itemClicked)="click($event)" (itemRemoved)="removeItem($event)" (loadNextPage)="load($event)" ...>
, but creating an interface we will need only one @Input()
:
import {Component, Input, OnInit} from '@angular/core';
export interface IdName{
id: number;
name: string;
}
export interface IListComponentCallback<T extends IdName> {
getList(page: number, limit: number): Promise< T[] >;
removeItem(item: T): Promise<boolean>;
click(item: T): void;
}
@Component({
selector: 'list-ctrl',
template: `
<button class="item" (click)="loadMore()">Load page {{page+1}}</button>
<div class="item" *ngFor="let item of list">
<button (click)="onDel(item)">DEL</button>
<div (click)="onClick(item)">
Id: {{item.id}}, Name: "{{item.name}}"
</div>
</div>
`,
styles: [`
.item{ margin: -1px .25rem 0; border: 1px solid #888; padding: .5rem; width: 100%; cursor:pointer; }
.item > button{ float: right; }
button.item{margin:.25rem;}
`]
})
export class ListComponent implements OnInit {
@Input() callback: IListComponentCallback<IdName>; // <-- CALLBACK
list: IdName[];
page = -1;
limit = 10;
async ngOnInit() {
this.loadMore();
}
onClick(item: IdName) {
this.callback.click(item);
}
async onDel(item: IdName){
if(await this.callback.removeItem(item)) {
const i = this.list.findIndex(i=>i.id == item.id);
this.list.splice(i, 1);
}
}
async loadMore(){
this.page++;
this.list = await this.callback.getList(this.page, this.limit);
}
}
Parent Component
Now we can use the list component in the parent.
import { Component } from "@angular/core";
import { SuggestionService } from "./suggestion.service";
import { IdName, IListComponentCallback } from "./list.component";
type Suggestion = IdName;
@Component({
selector: "my-app",
template: `
<list-ctrl class="left" [callback]="this"></list-ctrl>
<div class="right" *ngIf="msg">{{ msg }}<br/><pre>{{item|json}}</pre></div>
`,
styles:[`
.left{ width: 50%; }
.left,.right{ color: blue; display: inline-block; vertical-align: top}
.right{max-width:50%;overflow-x:scroll;padding-left:1rem}
`]
})
export class ParentComponent implements IListComponentCallback<Suggestion> {
msg: string;
item: Suggestion;
constructor(private suggApi: SuggestionService) {}
getList(page: number, limit: number): Promise<Suggestion[]> {
return this.suggApi.getSuggestions(page, limit);
}
removeItem(item: Suggestion): Promise<boolean> {
return this.suggApi.removeSuggestion(item.id)
.then(() => {
this.showMessage('removed', item);
return true;
})
.catch(() => false);
}
click(item: Suggestion): void {
this.showMessage('clicked', item);
}
private showMessage(msg: string, item: Suggestion) {
this.item = item;
this.msg = 'last ' + msg;
}
}
Note that the <list-ctrl>
receives this
(parent component) as the callback object.
One additional advantage is that it's not required to send the parent instance, it can be a service or any object that implements the interface if your use case allows it.
The complete example is on this stackblitz.
If you're getting this, you may have forgotten to put #include <thread>
