The hex editor plugin mentioned by ellak still works, but it seems that you need the TextFX Characters plugin as well.
I initially installed only the hex plugin and Notepad++ would no longer pop up; instead it started eating memory (killed it at 1.2 GB). I removed it again and for other reasons installed the TextFX plugin (based on Find multiple lines in Notepad++)
Out of curiosity I installed the hex plugin again and now it works.
Note that this is on a fresh install of Windows 7 64 bit.
Open the file using Notepad++ and check the "Encoding" menu, you can check the current Encoding and/or Convert to a set of encodings available.
You can add/edit content on multiple lines by using control button. This is multi edit feature in Notepad++, we need to enable it from settings. Press and hold control, select places where you want to enter text, release control and start typing, this will update the text at all the places selected previously.
Ref: http://notepad-plus-plus.org/features/multi-editing.html
With Nedit you can do several operations with selected column:
CTRL+LEFT-MOUSE -> Mark Rectangular Text-Area
MIDDLE-MOUSE pressed in area -> moving text area with pushing aside other text
CTRL+MIDDLE-MOUSE pressed in marked area -> moving text area with overriding aside text and deleting text from original position
CTRL+SHIFT+MIDDLE-MOUSE pressed in marked area -> copying text area with overriding aside text and keeping text from original position
I have a 32-bit Python 3.5 on a 64-bit Windows 8.1 machine. I just tried almost every way I can find on Stack Overflow and no one works!
Then on here I found it. It says:
SciPy is software for mathematics, science, and engineering.
Requires numpy+mkl.
Install numpy+mkl before installing scipy.
mkl matters!! But nobody said anything about that before!
Then I installed mkl:
C:\Users\****\Desktop\a> pip install mkl_service-1.1.2-cp35-cp35m-win32.whl
Processing c:\users\****\desktop\a\mkl_service-1.1.2-cp35-cp35m-win32.whl
Installing collected packages: mkl-service
Successfully installed mkl-service-1.1.2
Then I installed SciPy:
C:\Users\****\Desktop\a>pip install scipy-0.18.1-cp35-cp35m-win32.whl
Processing c:\users\****\desktop\a\scipy-0.18.1-cp35-cp35m-win32.whl
Installing collected packages: scipy
Successfully installed scipy-0.18.1
It worked~ yeah :)
A tip: You can just google "whl_file_name.whl" to know where to download it~ :)
Update:
After all these steps you will find that you still can not use SciPy in Python 3. If you print "import scipy" you will find there are error messages, but don't worry, there is only one more thing to do. Here ——just comment out that line, simple and useful.
from numpy._distributor_init import NUMPY_MKL
I promise that it is the last thing to do :)
PS: Before all these steps, you better install NumPy first. That's very simple using this command:
pip install numpy
You can save an html file with the extension 'xls' and accents will work (pre 2007 at least).
Example: save this (using Save As utf8 in Notepad) as test.xls:
<html>
<meta http-equiv="Content-Type" content="text/html" charset="utf-8" />
<table>
<tr>
<th>id</th>
<th>name</th>
</tr>
<tr>
<td>4</td>
<td>Hélène</td>
</tr>
</table>
</html>
If you use vim-plug (Plug), " A minimalist Vim plugin manager.":
:PlugStatus
That will not only list your plugins but check their status.
To check the existence of a local variable:
if 'myVar' in locals():
# myVar exists.
To check the existence of a global variable:
if 'myVar' in globals():
# myVar exists.
To check if an object has an attribute:
if hasattr(obj, 'attr_name'):
# obj.attr_name exists.
hello bro this is a way to read the string in the exact line using this code
hope this could help you !
#include <iostream>
#include <fstream>
using namespace std;
int main (){
string text[1];
int lineno ;
ifstream file("text.txt");
cout << "tell me which line of the file you want : " ;
cin >> lineno ;
for (int i = 0; i < lineno ; i++)
{
getline(file , text[0]);
}
cout << "\nthis is the text in which line you want befor :: " << text[0] << endl ;
system("pause");
return 0;
}
Good luck !
You need to instruct the console to clear.
For serial terminals this was typically done through so called "escape sequences", where notably the vt100 set has become very commonly supported (and its close ANSI-cousin).
Windows has traditionally not supported such sequences "out-of-the-box" but relied on API-calls to do these things. For DOS-based versions of Windows, however, the ANSI.SYS driver could be installed to provide such support.
So if you are under Windows, you need to interact with the appropriate Windows API. I do not believe the standard Java runtime library contains code to do so.
In POSIX systems, you don't find -r
parameter for grep
and your grep -rn "stuff" .
won't run, but if you use find
command it will:
find . -type f -exec grep -n "stuff" {} \; -print
Agreed by Solaris
and HP-UX
.
Meld can compare directories:
meld directory1 directory2
Just use the directories of the two git repos and you will get a nice graphical comparison:
When you click on one of the blue items, you can see what changed.
As @Agam said,
You need this statement in your driver file:
from AthleteList import AtheleteList
Use either the <button>
element or use an <input type="button"/>
.
Since GNU parallel was not mentioned yet, let me give another way:
cat url.list | parallel -j 8 wget -O {#}.html {}
Construction
With factories, Angular will invoke the function to get the result. It is the result that is cached and injected.
//factory
var obj = fn();
return obj;
With services, Angular will invoke the constructor function by calling new. The constructed function is cached and injected.
//service
var obj = new fn();
return obj;
Implementation
Factories typically return an object literal because the return value is what's injected into controllers, run blocks, directives, etc
app.factory('fn', function(){
var foo = 0;
var bar = 0;
function setFoo(val) {
foo = val;
}
function setBar (val){
bar = val;
}
return {
setFoo: setFoo,
serBar: setBar
}
});
Service functions typically do not return anything. Instead, they perform initialization and expose functions. Functions can also reference 'this' since it was constructed using 'new'.
app.service('fn', function () {
var foo = 0;
var bar = 0;
this.setFoo = function (val) {
foo = val;
}
this.setBar = function (val){
bar = val;
}
});
Conclusion
When it comes to using factories or services they are both very similar. They are injected into a controllers, directives, run block, etc, and used in client code in pretty much the same way. They are also both singletons - meaning the same instance is shared between all places where the service/factory is injected.
So which should you prefer? Either one - they are so similar that the differences are trivial. If you do choose one over the other, just be aware how they are constructed, so that you can implement them properly.
Either use:
pip install xlrd
And if you are using conda, use
conda install -c anaconda xlrd
That's it. good luck.
Here is a way to get the shell to do the substitution for you, as if the contents of the file were instead typed between double quotes.
Using the example of template.txt with contents:
The number is ${i}
The word is ${word}
The following line will cause the shell to interpolate the contents of template.txt and write the result to standard out.
i='1' word='dog' sh -c 'echo "'"$(cat template.txt)"'"'
Explanation:
i
and word
are passed as environment variables scopped to the execution of sh
.sh
executes the contents of the string it is passed.echo "
' + "$(cat template.txt)
" + '"
'"
, "$(cat template.txt)
" becomes the output of cat template.txt
.sh -c
becomes:
echo "The number is ${i}\nThe word is ${word}"
,i
and word
are the specified environment variables.left: initial
This will also set left
back to the browser default.
But important to know property: initial
is not supported in IE.
Use header
to modify the HTTP header:
header('Content-Type: text/html; charset=utf-8');
Note to call this function before any output has been sent to the client. Otherwise the header has been sent too and you obviously can’t change it any more. You can check that with headers_sent
. See the manual page of header
for more information.
In regards to the answer provided by Fuzzy:
I actually had to do something slightly different.
Project -> Properties -> C/C++ Build -> Settings -> GCC C Linker -> Libraries
Click the little green add icon, type m and hit ok. Everything in this window automatically has -l applied to it since it is a library.
If you're okay with using shorthands in your code (instead of writing explicit if
blocks, like some coding standards recommend), you can further simplify Marius Schulz's answer with this one-liner:
in_array ($value, $array) || $array [] = $value;
I use this function:
gcaa() { git add --all && git commit -m "$*" }
In my zsh config file, so i can just do:
> gcaa This is the commit message
To automatically stage and commit all files.
If so is there a way to not load the unnecessary content on mobile browsers?
use <img src="" srcset="">

You have configured the auth.php
and used members
table for authentication but there is no user_email
field in the members
table so, Laravel says
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'user_email' in 'where clause' (SQL: select * from members where user_email = ? limit 1) (Bindings: array ( 0 => '[email protected]', ))
Because, it tries to match the user_email
in the members
table and it's not there. According to your auth
configuration, laravel
is using members
table for authentication not users
table.
Another case is http redirection. If your page redirects http requests to https, then may be your partial view tries to redirect by itself.
It causes same problem again. For this problem, you can reorganize your .net error pages or iis error pages configuration.
Just make sure you are redirecting requests to right error or not found page and make sure this error page contains non problematic partial. If your page supports only https, do not forward requests to error page without using https, if error page contains partial, this partials tries to redirect seperately from requested url, it causes problem.
This should do it:
ALTER TABLE test MODIFY locationExpert VARCHAR(120)
I'm going to add a quick two cents to this. One reason this issue is confusing is because this scenario seems to return the same result with error reporting not on full:
$a = null;
var_dump($a); // NULL
var_dump($b); // NULL
You could assume from this result that the difference between $a = null
and not defining $b
at all is nothing.
Crank error reporting up:
NULL
Notice: Undefined variable: b in xxx on line n
NULL
Note: it threw an undefined variable error, but the output value of var_dump
is still NULL
.
PHP obviously does have an internal ability to distinguish between a null variable and an undefined variable. It seems to me that there should be a built in function to check for this.
I think the accepted answer is good for the most part, but if I was going to implement it I would write a wrapper for it. As previously mentioned in this answer, I have to agree that I haven't actually encountered a situation where this has been a problem. I seem to almost always end up in a scenario where my variables are either set and defined, or they aren't (undefined, unset, null, blank, etc). Not to say that a situation like this won't occur in future, but as it seems to be quite a unique issue I'm not surprised that the PHP devs haven't bothered to put this in.
So I added curl AFTER my docker container was running.
(This was for debugging the container...I did not need a permanent addition)
I ran my image
docker run -d -p 8899:8080 my-image:latest
(the above makes my "app" available on my machine on port 8899) (not important to this question)
Then I listed and created terminal into the running container.
docker ps
docker exec -it my-container-id-here /bin/sh
If the exec
command above does not work, check this SOF article:
Error: Cannot Start Container: stat /bin/sh: no such file or directory"
then I ran:
apk
just to prove it existed in the running container, then i ran:
apk add curl
and got the below:
apk add curl
fetch http://dl-cdn.alpinelinux.org/alpine/v3.8/main/x86_64/APKINDEX.tar.gz

then i ran curl:

Note, to get "out" of the drilled-in-terminal-window, I had to open a new terminal window and stop the running container:
docker ps
docker stop my-container-id-here
APPEND:
If you don't have "apk" (which depends on which base image you are using), then try to use "another" installer. From other answers here, you can try:
apt-get -qq update
apt-get -qq -y install curl
try next:
label[for="userName"] {_x000D_

<label for="userName">_x000D_
Name: _x000D_
<input type="text" name="userName" id="userName">_x000D_
</label>
_x000D_
This should work:
$('.myClass, .myOtherClass').removeClass('theclass');
You must add the multiple selectors all in the first argument to $(), otherwise you are giving jQuery a context in which to search, which is not what you want.
It's the same as you would do in CSS.
Your logic is backwards.
SELECT

In my opinion, the best solution involves neither images nor using the input's default value. Rather, it looks something like David Dorward's solution.
It's easy to implement and degrades nicely for screen readers and users with no javascript.
Take a look at the two examples here: http://attardi.org/labels/
I usually use the second method (labels2) on my forms.
You can loop through the Selection object to see what was selected. Here is a code snippet from Microsoft (http://msdn.microsoft.com/en-us/library/aa203726(office.11).aspx):
Sub Count_Selection()
Dim cell As Object
Dim count As Integer
count = 0
For Each cell In Selection
count = count + 1
Next cell
MsgBox count & " item(s) selected"
End Sub
If all you want is the file name without file extension
Dim fileNamesCol As New Collection
Dim MyFile As Variant 'Strings and primitive data types aren't allowed with collection
filePath = "c:\file directory" + "\"
MyFile = Dir$(filePath & "*.xlsx")
Do While MyFile <> ""
fileNamesCol.Add (Replace(MyFile, ".xlsx", ""))
MyFile = Dir$
Loop
To output to excel worksheet
Dim myWs As Worksheet: Set myWs = Sheets("SheetNameToDisplayTo")
Dim ic As Integer: ic = 1
For Each MyFile In fileNamesCol
myWs.Range("A" & ic).Value = fileNamesCol(ic)
ic = ic + 1
Next MyFile

When it can be the same header for all requests or you dispose the client after each request you can use the DefaultRequestHeaders.Add
option:
client.DefaultRequestHeaders.Add("apikey","xxxxxxxxx");
Because we make UI into XML but view objects is what we display so we somehow need to convert xml into view objects so inflating means we are converting xml into view objects so that it can be displayed, for this we need a service called layout inflator service and give it an xml and it will be convert for you.
This article helped me alot figuring out why it wasn't working for me either. It give me a lesson to think of the webpage loading and how angular 2 interacts as a timeline and not just the point in time i'm thinking of. I didn't see anyone else mention this point, so I will...
The reason the *ngIf is needed because it will try to check the length of that variable before the rest of the OnInit stuff happens, and throw the "length undefined" error. So thats why you add the ? because it won't exist yet, but it will soon.
Johann-S solution works great. (And it looks like he created the awesome plugin)
The Bootstrap 4.3 documentation example page uses this plugin to modify the filename: https://github.com/Johann-S/bs-custom-file-input
Use the Bootstrap custom file input classes. Add the plugin to your project, and add this code in your script file on the page.
$(document).ready(function () {
bsCustomFileInput.init()
})
No need too these. Just simply add div id to href of a < a > tag
<li><a id = "aboutlink" href="#about">auck</a></li>
Just like that.
How about writing out some HTML tags and some CSS if you're outputting this to the browser?
echo '<span style="color:#AFA;text-align:center;">Request has been sent. Please wait for my reply!</span>';
Won't work from console though, only through browser.
sudo apt-get install php7.0-mysql
for php7.0 works well for me
This will work also when the string is invalid or does not contain flags etc:
function regExpFromString(q) {_x000D_
let flags = q.replace(/.*\/([gimuy]*)$/, '$1');_x000D_
if (flags === q) flags = '';_x000D_
let pattern = (flags ? q.replace(new RegExp('^/(.*?)/' + flags + '$'), '$1') : q);_x000D_
try { return new RegExp(pattern, flags); } catch (e) { return null; }_x000D_
}_x000D_
_x000D_
console.log(regExpFromString('\\bword\\b'));_x000D_
console.log(regExpFromString('\/\\bword\\b\/gi'));_x000D_
_x000D_
Another option, if portability is not your main concern, is to use associative arrays that are built in to the shell. This should work in bash 4.0 (available now on most major distros, though not on OS X unless you install it yourself), ksh, and zsh:
declare -A newmap
newmap[name]="Irfan Zulfiqar"
newmap[designation]=SSE
newmap[company]="My Own Company"
echo ${newmap[company]}
echo ${newmap[name]}
Depending on the shell, you may need to do a typeset -A newmap
instead of declare -A newmap
, or in some it may not be necessary at all.
The distance between two coordinates x and y! x1 and y1 is the first point/position, x2 and y2 is the second point/position!

You can try to create the AlertDialog
object first, and then use it to set up to change the color of the button and then show it. (Note that on builder
object instead of calling show()
we call create()
to get the AlertDialog
object:
//1. create a dialog object 'dialog'
MyCustomDialog builder = new MyCustomDialog(getActivity(), "Try Again", errorMessage);
AlertDialog dialog = builder.setNegativeButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
...
}
}).create();
//2. now setup to change color of the button
dialog.setOnShowListener( new OnShowListener() {
@Override
public void onShow(DialogInterface arg0) {
dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(COLOR_I_WANT);
}
});
dialog.show()
The reason you have to do it on onShow()
and cannot just get that button after you create your dialog is that the button would not have been created yet.
I changed AlertDialog.BUTTON_POSITIVE
to AlertDialog.BUTTON_NEGATIVE
to reflect the change in your question. Although it is odd that "OK" button would be a negative button. Usually it is the positive button.

{
try
{
string str = ((DataRowView)dataGrid1.SelectedItem).Row["ColumnName"].ToString();

We found same issue building the project on Jenkins. With buildToolsVersion '25.0.2'
, we must accept licenses before building. In our case, we needed to run:
yes | sdkmanager --update
that accepts licenses for the sdkmanager itself, and then
yes | sdkmanager --licenses
that accepts new licenses not previously accepted
Remember: run these commans with the same user that jenkins
does. In our Debian, the Jenkins user is just jenkins
. In other words: doing it as root
will create the accepted licenses as root
, so Jenkins will not read them.
By the way, we found sdkmanager
at /var/lib/jenkins/tools/android-sdk/tools/bin
. If yours is not there, find it with find / -name "sdkmanager"
I don't believe search and replace will do it for you (doesn't work for me in Excel 2010 Home). Are you sure you want to put "null" in EVERY cell in the sheet? That is millions of cells, in which case there is no way a search and replace would be able to handle it memory-wise (correct me if I am wrong).
In the case I am right and you don't want millions of "null" cells, then here is a macro. It asks you to select the range then put "null" inside every cell that was blank.
Sub FillWithNull()
Dim cell As range
Dim myRange As range
Set myRange = Application.InputBox("Select the range", Type:=8)
Application.ScreenUpdating = False
For Each cell In myRange
If Len(cell) = 0 Then
cell.Value = "Null"
End If
Next
Application.ScreenUpdating = True
End Sub

Additional note: there is big difference between Debug assembler output and Release one. The first one is good to learn how compiler produces assembler code from C++. The second one is good to learn how compiler optimizes various C++ constructs. In this case some C++-to-asm transformations are not obvious.
@Autowired(required=false) By default the dependency injection for @Autowired must be fulfilled because the value of required attribute is true by default. We can change this behavior by using @Autowired(required=false). In this case if bean is not found for dependency injection, it will not through error.
Please have look at https://www.concretepage.com/spring/spring-autowired-annotation#required-false
But @Inject doesn’t need (required=false) it will not through error if dependency is not found

this code worked for me in partial view:
<a href="/Content/[email protected]">@item.Title</a>
FOR the best performance, use specific column name instead of * - for example:
SELECT TOP 1 <columnName>
FROM <tableName>
This is optimal because, instead of returning the whole list of columns, it is returning just one. That can save some time.
Also, returning just first row if there are any values, makes it even faster. Actually you got just one value as the result - if there are any rows, or no value if there is no rows.
If you use the table in distributed manner, which is most probably the case, than transporting just one value from the server to the client is much faster.
You also should choose wisely among all the columns to get data from a column which can take as less resource as possible.

Shift-Alt-J
is a useful keyboard shortcut in Eclipse for creating Javadoc comment templates.
Invoking the shortcut on a class, method or field declaration will create a Javadoc template:
public int doAction(int i) {

Pressing Shift-Alt-J
on the method declaration gives:
/**
* @param i
* @return
*/
public int doAction(int i) {

The real answer is here if you try to install bundler 2.0.1 or 2.0.0 due to Bundler requiring RubyGems v3.0.0
Yesterday I released Bundler 2.0 that introduced a number of breaking changes. One of the those changes was setting Bundler to require RubyGems v3.0.0. After making the release, it has become clear that lots of our users are running into issues with Bundler 2 requiring a really new version of RubyGems.
We have been listening closely to feedback from users and have decided to relax the RubyGems requirement to v2.5.0 at minimum. We have released a new Bundler version, v2.0.1, that adjusts this requirement.
For more info, see: https://bundler.io/blog/2019/01/04/an-update-on-the-bundler-2-release.html
In Debian Jessie, this works nice:
ls -lah --group-directories-first
# l=use a long listing format
# a=do not ignore entries starting with .
# h=human readable
# --group-directories-first=(obvious)
# Note: add -r for reverse alpha
# You might consider using lh by appending to ~/.bashrc as the alias:
~$ echo "alias lh='ls -lah --group-directories-first'" >>~/.bashrc
# -- restart your terminal before using lh command --

MONGO_INITDB_ROOT_USERNAME: my-user
MONGO_INITDB_ROOT_PASSWORD: my-password
and the last option is to manually access the container and set the user and password inside the mongo docker container
docker exec -it mongo-container bash
now you can use mongo shell command to configure everything that you want
I'm going to try this the following way. I've placed the count variable inside the "onfocus" function so as to keep it from becoming a global variable. The idea is to create a counter for each image in a tumblr blog.
$(document).ready(function() {
$("#image1").onfocus(function() {
var count;
if (count == undefined || count == "" || count == 0) {
var count = 0;
}
count++;
$("#counter1").html("Image Views: " + count);
}
});
Then, outside the script tags and in the desired place in the body I'll add:
<div id="counter1"></div>
The Range object has both width and height properties, which are measured in points.

The explanation from Scott Meyers in Effective C++ might help understand when to use them:
Public inheritance should model "is-a relationship," whereas private inheritance should be used for "is-implemented-in-terms-of" - so you don't have to adhere to the interface of the superclass, you're just reusing the implementation.
Suspend the process with CTRL+Z then use the command bg
to resume it in background. For example:
sleep 60
^Z #Suspend character shown after hitting CTRL+Z
[1]+ Stopped sleep 60 #Message showing stopped process info
bg #Resume current job (last job stopped)
More about job control and bg
usage in bash
manual page:
JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.
EDIT
To start a process where you can even kill the terminal and it still carries on running
nohup [command] [-args] > [filename] 2>&1 &
e.g.
nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &
To just ignore the output (not very wise) change the filename to /dev/null
To get the error message set to a different file change the &1
to a filename.
In addition: You can use the jobs
command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1
or kill %2
with the number being the index of the process.
You can use pd.Index.difference
with np.hstack
, then reindex
or use label-based indexing. In general, it's a good idea to avoid list comprehensions or other explicit loops with NumPy / Pandas objects.
cols_to_move = ['b', 'x']
new_cols = np.hstack((df.columns.difference(cols_to_move), cols_to_move))
# OPTION 1: reindex
df = df.reindex(columns=new_cols)
# OPTION 2: direct label-based indexing
df = df[new_cols]
# OPTION 3: loc label-based indexing
df = df.loc[:, new_cols]
print(df)
# a y b x
# 0 1 -1 2 3
# 1 2 -2 4 6
# 2 3 -3 6 9
# 3 4 -4 8 12
Take a look at "using WCF Services with PHP". It explains the basics of what you need.
As a theory summary:
WCF or Windows Communication Foundation is a technology that allow to define services abstracted from the way - the underlying communication method - they'll be invoked.
The idea is that you define a contract about what the service does and what the service offers and also define another contract about which communication method is used to actually consume the service, be it TCP, HTTP or SOAP.
You have the first part of the article here, explaining how to create a very basic WCF Service.
More resources:
Aslo take a look to NuSOAP. If you now NuSphere this is a toolkit to let you connect from PHP to an WCF service.
$matches = array();
preg_match('/id=([0-9]+)\?/', $url, $matches);
This is safe for if the format changes. slandau's answer won't work if you ever have any other numbers in the URL.
You could try setting up a filter using the unicodedata.category()
function:
import unicodedata
printable = {'Lu', 'Ll'}
def filter_non_printable(str):
return ''.join(c for c in str if unicodedata.category(c) in printable)
See Table 4-9 on page 175 in the Unicode database character properties for the available categories
If I may provide some historical context :
The term "slug" has to do with casting metal—lead, in this case—out of which the press fonts were made. Every paper then had its fonts factory regularly re-melted and recast in fresh molds, since after many prints they became worn out. Apprentices like me started their career there, and went all the way to the top (not anymore).
Typographs had to compose the text of an article in a backward manner with lead characters stacked in a wise. So at printing time the letters would be straight on the paper. All typographs could read the newspaper mirrored as fast as the printed one. Therefore the slugs, (like snails) also the slow stories (the last to be fixed) were many on the bench waiting, solely identified by their fist letters, mostly the whole title generally more readable. Some "hot" news were waiting there on the bench, for possible last minute correction, (Evening paper) before last assembly and definitive printing.
Django emerged from the offices of the Lawrence journal in Kansas. Where probably some printing jargon still lingers. A-django-enthusiast-&-friendly-old-slug-boy-from-France.

If you have Python 2.6 or newer, use format
:
'{0:.3g}'.format(num)
For Python 2.5 or older:
'%.3g'%(num)
Explanation:
{0}
tells format
to print the first argument -- in this case, num
.
Everything after the colon (:) specifies the format_spec
.
.3
sets the precision to 3.
g
removes insignificant zeros. See
http://en.wikipedia.org/wiki/Printf#fprintf
For example:
tests=[(1.00, '1'),
(1.2, '1.2'),
(1.23, '1.23'),
(1.234, '1.23'),
(1.2345, '1.23')]
for num, answer in tests:
result = '{0:.3g}'.format(num)
if result != answer:
print('Error: {0} --> {1} != {2}'.format(num, result, answer))
exit()
else:
print('{0} --> {1}'.format(num,result))
yields
1.0 --> 1
1.2 --> 1.2
1.23 --> 1.23
1.234 --> 1.23
1.2345 --> 1.23
Using Python 3.6 or newer, you could use f-strings
:
In [40]: num = 1.234; f'{num:.3g}'
Out[40]: '1.23'
If this is a programming question, then I would suggest you write your own regular expression to parse all the retrieved contents. Target tags are IMG and A for standard HTML. For JAVA,
final String openingTags = "(<a [^>]*href=['\"]?|<img[^> ]* src=['\"]?)";
this along with Pattern and Matcher classes should detect the beginning of the tags. Add LINK tag if you also want CSS.
However, it is not as easy as you may have intially thought. Many web pages are not well-formed. Extracting all the links programmatically that human being can "recognize" is really difficult if you need to take into account all the irregular expressions.
Good luck!
For simplicity I will use bytes:
byte a=250;
byte b=8;
byte c=a+b;
if a, b, and c were 'int', you would expect 258, but in the case of 'byte', the expected result would be 2 (258 & 0xFF), but in a Windows application you get an exception, in a console one you may not (I don't, but this may depend on IDE, I use SharpDevelop).
Sometimes, however, that behaviour is desired (e.g. you only care about the lower 8 bits of the result).
You could do the following:
byte a=250;
byte b=8;
byte c=(byte)((int)a + (int)b);
This way both 'a' and 'b' are converted to 'int', added, then casted back to 'byte'.
To be on the safe side, you may also want to try:
...
byte c=(byte)(((int)a + (int)b) & 0xFF);
Or if you really want that behaviour, the much simpler way of doing the above is:
unchecked
{
byte a=250;
byte b=8;
byte c=a+b;
}
Or declare your variables first, then do the math in the 'unchecked' section.
Alternately, if you want to force the checking of overflow, use 'checked' instead.
Hope this clears things up.

P.S.
Trust me, that exception is your friend :)
Try this...
Give the element an ID, and also a class Name. Then you can nest the #IDName.className in your CSS.
Here's a better explanation https://css-tricks.com/multiple-class-id-selectors/
Delphi used properties and they have found their way into .NET (because it has the same architect).
In Delphi they are often used in combination with runtime type information such that the integrated property editor can be used to set the property in designtime.
Properties are not always related to fields. They can be functions that possible have side effects (but of course that is very bad design).
The code project article Creating a Tasktray Application gives a very simple explanation and example of creating an application that only ever exists in the System Tray.
Basically change the Application.Run(new Form1());
line in Program.cs
to instead start up a class that inherits from ApplicationContext
, and have the constructor for that class initialize a NotifyIcon
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MyCustomApplicationContext());
}
}
public class MyCustomApplicationContext : ApplicationContext
{
private NotifyIcon trayIcon;
public MyCustomApplicationContext ()
{
// Initialize Tray Icon
trayIcon = new NotifyIcon()
{
Icon = Resources.AppIcon,
ContextMenu = new ContextMenu(new MenuItem[] {
new MenuItem("Exit", Exit)
}),
Visible = true
};
}
void Exit(object sender, EventArgs e)
{
// Hide tray icon, otherwise it will remain shown until user mouses over it
trayIcon.Visible = false;
Application.Exit();
}
}
One of the simplest way is to use flatten()
, like this example :
import numpy as np
batch_y =train_output.iloc[sample, :]
batch_y = np.array(batch_y).flatten()
My array it was like this :
0
0 6
1 6
2 5
3 4
4 3
.
.
.
After using flatten()
:
array([6, 6, 5, ..., 5, 3, 6])
It's also the solution of errors of this type :
Cannot feed value of shape (100, 1) for Tensor 'input/Y:0', which has shape '(?,)'
There are now safer methods to accomplish this. The docs have been updated with these methods.
Other Methods
Easiest - Use Unicode, save the file as UTF-8 and set the charset
to UTF-8.
<div>{'First · Second'}</div>
Safer - Use the Unicode number for the entity inside a Javascript string.
<div>{'First \u00b7 Second'}</div>
or
<div>{'First ' + String.fromCharCode(183) + ' Second'}</div>
Or a mixed array with strings and JSX elements.
<div>{['First ', <span>·</span>, ' Second']}</div>
Last Resort - Insert raw HTML using dangerouslySetInnerHTML
.
<div dangerouslySetInnerHTML={{__html: 'First · Second'}} />
First check if the user has granted the permission:
if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA)
== PackageManager.PERMISSION_DENIED)
Then, you could use this to request to the user:
ActivityCompat.requestPermissions(activity, new String[] {Manifest.permission.CAMERA}, requestCode);
And in Marshmallow, it will appear in a dialog
This worked for me on my 2017 imac macOS Mojave (Version 10.14.3).
Open your ~/.bash_profile:
nano ~/.bash_profile
Append the alias:
alias pycharm="open /Applications/PyCharm\ CE.app"
Update terminal:
source ~/.bash_profile
Assert that it works:
pycharm
Using Node.js
sync mode:
var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")
async mode:
var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
var textByLine = text.split("\n")
});
UPDATE
As of at least Node 6, readFileSync
returns a Buffer
, so it must first be converted to a string in order for split
to work:
var text = fs.readFileSync("./mytext.txt").toString('utf-8');
Or
var text = fs.readFileSync("./mytext.txt", "utf-8");
I will show you a whole example of servlet & how do ajax call.
Here, we are going to create the simple example to create the login form using servlet.
index.html
<form>
Name:<input type="text" name="username"/><br/><br/>
Password:<input type="password" name="userpass"/><br/><br/>
<input type="button" value="login"/>
</form>
Here is ajax Sample
$.ajax
({
type: "POST",
data: 'LoginServlet='+name+'&name='+type+'&pass='+password,
url: url,
success:function(content)
{
$('#center').html(content);
}
});
LoginServlet Servlet Code :-
package abc.servlet;
import java.io.File;
public class AuthenticationServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
doPost(request, response);
}
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
try{
HttpSession session = request.getSession();
String username = request.getParameter("name");
String password = request.getParameter("pass");
/// Your Code
out.println("sucess / failer")
} catch (Exception ex) {
// System.err.println("Initial SessionFactory creation failed.");
ex.printStackTrace();
System.exit(0);
}
}
}
This has been working for me:
If you try uploading the new file as a war file, with tomcat still running, it will attempt to expand it before it is all there. It will fail. Having failed, it will not try again. Thus, uploading a www file, then renaming it, allows the whole war file to be present before tomcat notices it.
Hint, don't forget to check that the war file's owner is tomcat (Use chown)
you're almost there: just don't call toString()
on Html.fromHtml()
and you get a Spanned Object which will do the job ;)
tvHide.setText(Html.fromHtml("<p><u>Hide post</u></p>"));
Also make sure you are not using an USB cable designated for charging only. This just got me. And it actually was labelled "for charging only"
Position Independent Code means that the generated machine code is not dependent on being located at a specific address in order to work.
E.g. jumps would be generated as relative rather than absolute.
Pseudo-assembly:
PIC: This would work whether the code was at address 100 or 1000
100: COMPARE REG1, REG2
101: JUMP_IF_EQUAL CURRENT+10
...
111: NOP
Non-PIC: This will only work if the code is at address 100
100: COMPARE REG1, REG2
101: JUMP_IF_EQUAL 111
...
111: NOP
EDIT: In response to comment.
If your code is compiled with -fPIC, it's suitable for inclusion in a library - the library must be able to be relocated from its preferred location in memory to another address, there could be another already loaded library at the address your library prefers.
The error you quote has nothing to do with pg_hba.conf
; it's failing to connect, not failing to authorize the connection.
Do what the error message says:
Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections
You haven't shown the command that produces the error. Assuming you're connecting on localhost
port 5432
(the defaults for a standard PostgreSQL install), then either:
PostgreSQL isn't running
PostgreSQL isn't listening for TCP/IP connections (listen_addresses
in postgresql.conf
)
PostgreSQL is only listening on IPv4 (0.0.0.0
or 127.0.0.1
) and you're connecting on IPv6 (::1
) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.
PostgreSQL is listening on a different port to the one you're connecting on
(unlikely) there's an iptables
rule blocking loopback connections
(If you are not connecting on localhost
, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).
So ... check those:
ps -f -u postgres

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:
$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 12345?
Tested and working!

Run your Spring Boot application with the given command to enable debugging on port 6006 while the server is up on port 8090:
mvn spring-boot:run -Drun.jvmArguments='-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=6006' -Dserver.port=8090
If you are producing the entire output yourself, you can use sprintf()
, e.g.
> sprintf("%.10f",0.25)
[1] "0.2500000000"
specifies that you want to format a floating point number with ten decimal points (in %.10f
the f
is for float and the .10
specifies ten decimal points).
I don't know of any way of forcing R's higher level functions to print an exact number of digits.
Displaying 100 digits does not make sense if you are printing R's usual numbers, since the best accuracy you can get using 64-bit doubles is around 16 decimal digits (look at .Machine$double.eps on your system). The remaining digits will just be junk.
You still have to wrap it in an ISERROR, but you could use MATCH()
instead of VLOOKUP()
:
Returns the relative position of an item in an array that matches a specified value in a specified order. Use MATCH instead of one of the LOOKUP functions when you need the position of an item in a range instead of the item itself.
Here's a complete example, assuming you're looking for the word "key" in a range of cells:
=IF(ISERROR(MATCH("key",A5:A16,FALSE)),"missing","found")
The FALSE
is necessary to force an exact match, otherwise it will look for the closest value.
The exact thing you want ;)

Give the UL an ID and use the getElementById function:
<html>
<body>
<script>
function toggledisplay(elementID)
{
(function(style) {
style.display = style.display === 'none' ? '' : 'none';
})(document.getElementById(elementID).style);
}
</script>
<a href="#" title="Show Tags" onClick="toggledisplay('changethis');">Show All Tags</a>
<ul class="subforums" id="changethis" style="overflow-x: visible; overflow-y: visible; ">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
</body>
</html>
You can use these Extension Methods: (Save as PartialWithScript.cs)
namespace System.Web.Mvc.Html
{
public static class PartialWithScript
{
public static void RenderPartialWithScript(this HtmlHelper htmlHelper, string partialViewName)
{
if (htmlHelper.ViewBag.ScriptPartials == null)
{
htmlHelper.ViewBag.ScriptPartials = new List<string>();
}
if (!htmlHelper.ViewBag.ScriptPartials.Contains(partialViewName))
{
htmlHelper.ViewBag.ScriptPartials.Add(partialViewName);
}
htmlHelper.ViewBag.ScriptPartialHtml = true;
htmlHelper.RenderPartial(partialViewName);
}
public static void RenderPartialScripts(this HtmlHelper htmlHelper)
{
if (htmlHelper.ViewBag.ScriptPartials != null)
{
htmlHelper.ViewBag.ScriptPartialHtml = false;
foreach (string partial in htmlHelper.ViewBag.ScriptPartials)
{
htmlHelper.RenderPartial(partial);
}
}
}
}
}
Use like this:
Example partial: (_MyPartial.cshtml) Put the html in the if, and the js in the else.
@if (ViewBag.ScriptPartialHtml ?? true)
<p>I has htmls</p>
}
else {
<script type="text/javascript">
alert('I has javascripts');
</script>
}
In your _Layout.cshtml, or wherever you want the scripts from the partials on to be rendered, put the following (once): It will render only the javascript of all partials on the current page at this location.
@{ Html.RenderPartialScripts(); }
Then to use your partial, simply do this: It will render only the html at this location.
@{Html.RenderPartialWithScript("~/Views/MyController/_MyPartial.cshtml");}

You could use flatMap. It can filter and map in one.

Yes, it is used all the time for testing. It is very likely that the testing framework uses .equals() for comparisons such as these.
Below is a link explaining the "string equality mistake". Essentially, strings in Java are objects, and when you compare object equality, typically they are compared based on memory address, and not by content. Because of this, two strings won't occupy the same address, even if their content is identical, so they won't match correctly, even though they look the same when printed.

No, there is no such method. The end of iteration is indicated by an exception. See the documentation.
It may be that it's not loading the template you expect. I added a new class that inherited from UpdateView
- I thought it would automatically pick the template from what I named my class, but it actually loaded it based on the model
property on the class, which resulted in another (wrong) template being loaded. Once I explicitly set template_name
for the new class, it worked fine.
The following command will (1) compare the file of the correct branch, to master (2) interactively ask you which modifications to apply.

Give "write" permission to the directory you need to put the file. In your case it is the current directory.

Add "Everyone" with "write" enabled to the security tab of the directory if you are in Windows.

versionCode
A positive integer used as an internal version number. This number is used only to determine whether one version is more recent than another, with higher numbers indicating more recent versions. This is not the version number shown to users; that number is set by the versionName
setting, below. The Android system uses the versionCode
value to protect against downgrades by preventing users from installing an APK with a lower versionCode
than the version currently installed on their device.
The value is a positive integer so that other apps can programmatically evaluate it, for example to check an upgrade or downgrade relationship. You can set the value to any positive integer you want, however you should make sure that each successive release of your app uses a greater value. You cannot upload an APK to the Play Store with a versionCode
you have already used for a previous version.
versionName
A string used as the version number shown to users. This setting can be specified as a raw string or as a reference to a string resource.
The value is a string so that you can describe the app version as a .. string, or as any other type of absolute or relative version identifier. The versionName
has no purpose other than to be displayed to users.
One of the main reasons for the issue is the CSS file which is trying to load isn't a valid CSS file.
Causes:
Check the file which you're trying to load is a valid CSS style sheet (get the server URL of the file from the network tab and hit in a new tab and verify).
Useful info for consideration when using <link> inside the body tag.
Though having a link
tag inside the body is not the standard way to use the tag. But we can use it for page optimization (more information: https://developers.google.com/speed/docs/insights/OptimizeCSSDelivery) / if the business use case demands (when you serve the body of the content and server configured to have to render the HTML page with content provided).
While keeping inside the body tag we have to add the attribute itemProperty
in the link
tag like
<body>
<!-- … -->
<link itemprop="url" href="http://en.wikipedia.org/wiki/The_Catcher_in_the_Rye" />
<!-- … -->
</body>`
For more information on itemProperty
have a look in https://webmasters.stackexchange.com/questions/55130/can-i-use-link-tags-in-the-body-of-an-html-document.
In my case, the problem was resolved after I tried a lower version of Pixel and Android.
It's not a good way, but for me it seems the most simplest.
Add an anchor tag which contains the modal data-target and data-toggle, have an id associated with it. (Can be added mostly anywhere in the html view)
<a href="" data-toggle="modal" data-target="#myModal" id="myModalShower"></a>
Now,
Inside the angular controller, from where you want to trigger the modal just use
angular.element('#myModalShower').trigger('click');
This will mimic a click to the button based on the angular code and the modal will appear.
public void methodOnClick(View view){
Button.setBackgroundResource(R.drawable.nameImage);
}
i recommend use button inside LinearLayout for adjust to size of Linear.

If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?
If your background image is a vertically aligned sprite sheet, you can horizontally center each sprite like this:
#doit {
background-image: url('images/pic.png');
background-repeat: none;
background-position: 50% [y position of sprite];
}
If your background image is a horizontally aligned sprite sheet, you can vertically center each sprite like this:
#doit {
background-image: url('images/pic.png');
background-repeat: none;
background-position: [x position of sprite] 50%;
}
If your sprite sheet is compact, or you are not trying to center your background image in one of the aforementioned scenarios, these solutions do not apply.
Your regex pattern should have the g modifier:
var pattern = /[somepattern]+/g;
notice the g at the end. it tells the replacer to do a global replace.
Also you dont need to use the RegExp object you can construct your pattern as above. Example pattern:
var pattern = /[0-9a-zA-Z]+/g;
a pattern is always surrounded by / on either side - with modifiers after the final /, the g modifier being the global.
EDIT: Why does it matter if pattern is a variable? In your case it would function like this (notice that pattern is still a variable):
var pattern = /[0-9a-zA-Z]+/g;
repeater.replace(pattern, "1234abc");
But you would need to change your replace function to this:
this.markup = this.markup.replace(pattern, value);
So for me, nobody gave the good answer to the problem that i met which is almost the same than @Kay. For me it's about sorting, sorting table does not occur changes in the mat. I purpose this answer since it's the only topic that i find by searching google. I'm using Angular 6.
As said here:
Since the table optimizes for performance, it will not automatically check for changes to the data array. Instead, when objects are added, removed, or moved on the data array, you can trigger an update to the table's rendered rows by calling its renderRows() method.
So you just have to call renderRows() in your refresh() method to make your changes appears.
See here for integration.

You're missing your database name:
$sql = "SELECT ID, ListStID, ListEmail, Title FROM ".$entry_database." WHERE ID = ". $ReqBookID .";
And make sure that $entry_database isn't null or empty:
var_dump($entry_database);
Also notice that you don't need to have $ReqBookID in '' as if it's an Int.
Improving on the answer by @Alex, I suggest the following:
using (EventLog eventLog = new EventLog("Application"))
{
//You cannot be sure if the current identity has permissions to register the event source.
try
{
if (System.Web.HttpRuntime.AppDomainAppId != null)
{
eventLog.Source = System.Web.HttpRuntime.AppDomainAppId;
}
else
{
eventLog.Source = Process.GetCurrentProcess().ProcessName;
}
}
catch (SecurityException)
{
eventLog.Source = "Application";
}
eventLog.WriteEntry("Log message example", EventLogEntryType.Information, 1000);
}
It is important here not to specify category
parameter. If you do, and this is the same for the .NET Runtime
so-called magic, the
The description for Event ID <...> from source <...> cannot be found.

In my case I had to make a POST request, which had information sent through the header, and also a file sent using a FormData object.
I made it work using a combination of some of the answers here, so basically what ended up working was having this five lines in my Ajax request:
contentType: "application/octet-stream",
enctype: 'multipart/form-data',
contentType: false,
processData: false,
data: formData,
Where formData was a variable created like this:
var file = document.getElementById('uploadedFile').files[0];
var form = $('form')[0];
var formData = new FormData(form);
formData.append("File", file);
Witty example, Ryan, to end with a link to the function. Well done.
One recommendation Brian: if you wrap this code in a function, you may want to use a UriBuilder to wrap the base URL prior to the TryCreate call.
Otherwise, the base URL MUST include the scheme (where the UriBuilder will assume http://). Just a thought:
public string CombineUrl(string baseUrl, string relativeUrl) {
UriBuilder baseUri = new UriBuilder(baseUrl);
Uri newUri;
if (Uri.TryCreate(baseUri.Uri, relativeUrl, out newUri))
return newUri.ToString();
else
throw new ArgumentException("Unable to combine specified url values");
}

A null pointer has a reserved value, often but not necessarily the value zero, indicating that it refers to no object
..Since a null-valued pointer does not refer to a meaningful object, an attempt to dereference a null pointer usually causes a run-time error.
int val =1;
int *p = NULL;
*p = val; // Whooosh!!!!

The local names for a function are decided when the function is defined:
>>> x = 1
>>> def inc():
... x += 5
...
>>> inc.__code__.co_varnames
('x',)
In this case, x
exists in the local namespace. Execution of x += 5
requires a pre-existing value for x
(for integers, it's like x = x + 5
), and this fails at function call time because the local name is unbound - which is precisely why the exception UnboundLocalError
is named as such.
Compare the other version, where x
is not a local variable, so it can be resolved at the global scope instead:
>>> def incg():
... print(x)
...
>>> incg.__code__.co_varnames
()

I've managed to get this working by the following fix:

You video should have the hd720 resolution to do so.

As others have pointed out, accessing dicts in Python is fast. They are probably the best-oiled data structure in the language, given their central role. The problem lies elsewhere.
How many tuples are you memoizing? Have you considered the memory footprint? Perhaps you are spending all your time in the memory allocator or paging memory.
private string GetFileSize(double byteCount)
{
string size = "0 Bytes";
if (byteCount >= 1073741824.0)
size = String.Format("{0:##.##}", byteCount / 1073741824.0) + " GB";
else if (byteCount >= 1048576.0)
size = String.Format("{0:##.##}", byteCount / 1048576.0) + " MB";
else if (byteCount >= 1024.0)
size = String.Format("{0:##.##}", byteCount / 1024.0) + " KB";
else if (byteCount > 0 && byteCount < 1024.0)
size = byteCount.ToString() + " Bytes";
return size;
}
private void btnBrowse_Click(object sender, EventArgs e)
{
if (openFile1.ShowDialog() == DialogResult.OK)
{
FileInfo thisFile = new FileInfo(openFile1.FileName);
string info = "";
info += "File: " + Path.GetFileName(openFile1.FileName);
info += Environment.NewLine;
info += "File Size: " + GetFileSize((int)thisFile.Length);
label1.Text = info;
}
}
This is one way to do it aswell (The number 1073741824.0 is from 1024*1024*1024 aka GB)
You get this message when you've used async in your template, but are referring to an object that isn't an Observable.
So for examples sake, lets' say I had these properties in my class:
job:Job
job$:Observable<Job>
Then in my template, I refer to it this way:
{{job | async }}
instead of:
{{job$ | async }}
You wouldn't need the job:Job property if you use the async pipe, but it serves to illustrate a cause of the error.
Here is my CORS middleware:
<?php namespace App\Http\Middleware;
use Closure;
class CORS {
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
header("Access-Control-Allow-Origin: *");
// ALLOW OPTIONS METHOD
$headers = [
'Access-Control-Allow-Methods'=> 'POST, GET, OPTIONS, PUT, DELETE',
'Access-Control-Allow-Headers'=> 'Content-Type, X-Auth-Token, Origin'
];
if($request->getMethod() == "OPTIONS") {
// The client-side application can set only headers allowed in Access-Control-Allow-Headers
return Response::make('OK', 200, $headers);
}
$response = $next($request);
foreach($headers as $key => $value)
$response->header($key, $value);
return $response;
}
}
To use CORS middleware you have to register it first in your app\Http\Kernel.php file like this:
protected $routeMiddleware = [
//other middlewares
'cors' => 'App\Http\Middleware\CORS',
];
Then you can use it in your routes
Route::get('example', array('middleware' => 'cors', 'uses' => 'ExampleController@dummy'));
The awk is ok. I'm guessing the file is from a windows system and has a CR (^m ascii 0x0d) on the end of the line.
This will cause the cursor to go to the start of the line after $2.
Use dos2unix or vi with :se ff=unix
to get rid of the CRs.
Portland group have a commercial product called CUDA x86, it is hybrid compiler which creates CUDA C/ C++ code which can either run on GPU or use SIMD on CPU, this is done fully automated without any intervention for the developer. Hope this helps.
I had the same issue and I was "Running" the tests. If I instead "Debug" the tests the Debug output shows just fine like all others Trace and Console. I don't know though how to see the output if you "Run" the tests.
Try this snippet of code
private static boolean isStringInt(String s){
Scanner in=new Scanner(s);
return in.hasNextInt();
}
You can use the Screen.PrimaryScreen.Bounds
to retrieve the size of the primary monitor (or inspect the Screen
object to retrieve all monitors). Use those with MyForms.Bounds
to figure out where to place your form.

Another possible problem (which I ran into):
Be sure that the ProjectInstaller
class is public
. To be honest, I am not sure how exactly I did it, but I added event handlers to ProjectInstaller.Designer.cs
, like:
this.serviceProcessInstaller1.BeforeInstall += new System.Configuration.Install.InstallEventHandler(this.serviceProcessInstaller1_BeforeInstall);
I guess during the automatical process of creating the handler function in ProjectInstaller.cs
it changed the class definition from
public class ProjectInstaller : System.Configuration.Install.Installer
to
partial class ProjectInstaller : System.Configuration.Install.Installer
replacing the public
keyword with partial
. So, in order to fix it it must be
public partial class ProjectInstaller : System.Configuration.Install.Installer
I use Visual Studio 2013 Community edition.
For Evergreen browsers, this will build a staircase based on an incoming character and the number of stairs to build.
function StairCase(character, input) {
let i = 0;
while (i < input) {
const spaces = " ".repeat(input - (i+1));
const hashes = character.repeat(i + 1);
console.log(spaces + hashes);
i++;
}
}
//Implement
//Refresh the console
console.clear();
StairCase("#",6);
You can also add a polyfill for Repeat for older browsers

For the new Criteria since version Hibernate 5.2:
CriteriaBuilder criteriaBuilder = getSession().getCriteriaBuilder();
CriteriaQuery<SomeClass> criteriaQuery = criteriaBuilder.createQuery(SomeClass.class);
Root<SomeClass> root = criteriaQuery.from(SomeClass.class);
Path<Object> expressionA = root.get("A");
Path<Object> expressionB = root.get("B");
Predicate predicateAEqualX = criteriaBuilder.equal(expressionA, "X");
Predicate predicateBInXY = expressionB.in("X",Y);
Predicate predicateLeft = criteriaBuilder.and(predicateAEqualX, predicateBInXY);
Predicate predicateAEqualY = criteriaBuilder.equal(expressionA, Y);
Predicate predicateBEqualZ = criteriaBuilder.equal(expressionB, "Z");
Predicate predicateRight = criteriaBuilder.and(predicateAEqualY, predicateBEqualZ);
Predicate predicateResult = criteriaBuilder.or(predicateLeft, predicateRight);
criteriaQuery

Just use TO_DATE()
function to convert string to DATE
.
For Example:
create table Customer(
CustId int primary key,
CustName varchar(20),
DOB date);
insert into Customer values(1,'Vishnu', TO_DATE('1994/12/16 12:00:00', 'yyyy/mm/dd hh:mi:ss'));
Addition to previous answer make sure that your curl installation supports https.
You can use curl --version
to get information about supported protocols.
If your curl supports https follow the previous answer.
curl --cert certificate_path:password https://www.example.com
If it does not support https, you need to install a cURL version that supports https.
I have different approach if you want access token and make call to other resource system with access token in header
Spring Security comes with automatic security: oauth2 properties access from application.yml file for every request and every request has SESSIONID which it reads and pull user info via Principal, so you need to make sure inject Principal in OAuthUser and get accessToken and make call to resource server

security:
oauth2:

Multi thread example to calculate directory size from Microsoft Docs, which would be faster
using System;
using System.IO;
using System.Threading;
using System.Threading.Tasks;
public class Example
{
public static void Main()
{
long totalSize = 0;
String[] args = Environment.GetCommandLineArgs();
if (args.Length == 1) {
Console.WriteLine("There are no command line arguments.");
return;
}
if (! Directory.Exists(args[1])) {
Console.WriteLine("The directory does not exist.");
return;
}
String[] files = Directory.GetFiles(args[1]);
Parallel.For(0, files.Length,
index => { FileInfo fi = new FileInfo(files[index]);
long size = fi.Length;
Interlocked.Add(ref totalSize, size);
} );
Console.WriteLine("Directory '{0}':", args[1]);
Console.WriteLine("{0:N0} files, {1:N0} bytes", files.Length, totalSize);
}
}
// The example displaysoutput like the following:
// Directory 'c:\windows\':
// 32 files, 6,587,222 bytes
This example only calculate the files in current folder, so if you want to calculate all the files recursively, you can change the
String[] files = Directory.GetFiles(args[1]);
to
String[] files = Directory.GetFiles(args[1], "*", SearchOption.AllDirectories);
Create a file called "SetFile.bat" that contains the following line with no carriage return at the end of it...
set FileContents=
Then in your batch file do something like this...
@echo off
copy SetFile.bat + %1 $tmp$.bat > nul
call $tmp$.bat
del $tmp$.bat
%1 is the name of your input file and %FileContents% will contain the contents of the input file after the call. This will only work on a one line file though (i.e. a file containing no carriage returns). You could strip out/replace carriage returns from the file before calling the %tmp%.bat if needed.
Encoding targetEncoding = Encoding.GetEncoding(1252);
// Encode a string into an array of bytes.
Byte[] encodedBytes = targetEncoding.GetBytes(utfString);
// Show the encoded byte values.
Console.WriteLine("Encoded bytes: " + BitConverter.ToString(encodedBytes));
// Decode the byte array back to a string.
String decodedString = Encoding.Default.GetString(encodedBytes);

I just had the same question but with irregularly spaced datapoints. Resample is not really an option here. So I created my own function. Maybe it will be useful for others too:
from pandas import Series, DataFrame
import pandas as pd
from datetime import datetime, timedelta
import numpy as np
def rolling_mean(data, window, min_periods=1, center=False):
''' Function that computes a rolling mean
Parameters
----------
data : DataFrame or Series
If a DataFrame is passed, the rolling_mean is computed for all columns.
window : int or string
If int is passed, window is the number of observations used for calculating
the statistic, as defined by the function pd.rolling_mean()
If a string is passed, it must be a frequency string, e.g. '90S'. This is
internally converted into a DateOffset object, representing the window size.
min_periods : int
Minimum number of observations in window required to have a value.
Returns
-------
Series or DataFrame, if more than one column
'''

'''Function to apply that actually computes the rolling mean'''

Using vlines
:

np.random.seed(5)
x = arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
p = plot(x, y, "o")
vlines(70,100,250)
The basic call signatures are:
vlines(x, ymin, ymax)
hlines(y, xmin, xmax)
try this scp -r -P2222 [email protected]:/home2/kwazy/www/utrecht-connected.nl /Desktop
Another easier option if you're going to be pulling files left and right is to just use an SFTP client like WinSCP. Then you're not typing out 100 characters every time you want to pull something, just drag and drop.
Edit: Just noticed /Desktop probably isn't where you're looking to download the file to. Should be something like C:\Users\you\Desktop
Java always takes arguments as a string type...(String args[]) so you need to convert in your desired type.
Integer.parseInt()
to convert your string into Interger.System.out.println()
Example :
int a;
a = Integer.parseInt(args[0]);
and for Standard Input you can use codes like
StdIn.readInt();
StdIn.readString();

String.prototype.capitalize = function(allWords) {
return (allWords) ? // If all words
this.split(' ').map(word => word.capitalize()).join(' ') : // Break down the phrase to words and then recursive
// calls until capitalizing all words
this.charAt(0).toUpperCase() + this.slice(1); // If allWords is undefined, capitalize only the first word,
// meaning the first character of the whole string
}
And then:
"capitalize just the first word".capitalize(); ==> "Capitalize just the first word"
"capitalize all words".capitalize(true); ==> "Capitalize All Words"
const capitalize = (string = '') => [...string].map( // Convert to array with each item is a char of
// string by using spread operator (...)
(char, index) => index ? char : char.toUpperCase() // Index true means not equal 0, so (!index) is
// the first character which is capitalized by
// the `toUpperCase()` method
).join('') // Return back to string
then capitalize("hello") // Hello
This adds a "log" function to the local scope (using this
) using as many arguments as you want:
this.log = function() {
var args = [];
args.push('[' + new Date().toUTCString() + '] ');
//now add all the other arguments that were passed in:
for (var _i = 0, _len = arguments.length; _i < _len; _i++) {
arg = arguments[_i];
args.push(arg);
}
//pass it all into the "real" log function
window.console.log.apply(window.console, args);
}
So you can use it:
this.log({test: 'log'}, 'monkey', 42);
Outputs something like this:
[Mon, 11 Mar 2013 16:47:49 GMT] Object {test: "log"} monkey 42
So, I was having the same issue, but trying to import Android code via the "Import..." menu. When neither of the above two solutions worked on Eclipse Juno:
Eclipse -> File -> Import -> General -> Existing Project Into Workspace (NOTE: NOT 'EXISTING ANDROID PROJECT')
(Projects should import correctly, but should have errors. We must now attach the SDK to the project)
Right-Click on the project, Properties->Android->Project Build Target Choose the appropriate build target (in doubt, use 4.0.3 in the project is newish, and use 2.2 if the project is oldish)
Click OK
Once the project rebuilds, everything should be back in order.
(This was written when Eclipse Indigo was in vogue, and there may be changes as Google updates their tools to cover corner cases.)
One More way to send objects through bundle is by using bundle.putByteArray
Sample code
public class DataBean implements Serializable {
private Date currentTime;
public setDate() {
currentTime = Calendar.getInstance().getTime();
}
public Date getCurrentTime() {
return currentTime;
}
}
put Object of DataBean in to Bundle:
class FirstClass{
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Your code...
//When you want to start new Activity...
Intent dataIntent =new Intent(FirstClass.this, SecondClass.class);
Bundle dataBundle=new Bundle();
DataBean dataObj=new DataBean();
dataObj.setDate();
try {
dataBundle.putByteArray("Obj_byte_array", object2Bytes(dataObj));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
dataIntent.putExtras(dataBundle);
startActivity(dataIntent);
}
Converting objects to byte arrays
/**
* Converting objects to byte arrays
*/
static public byte[] object2Bytes( Object o ) throws IOException {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream( baos );
oos.writeObject( o );
return baos.toByteArray();
}
Get Object back from Bundle:
class SecondClass{
DataBean dataBean;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Your code...
//Get Info from Bundle...
Bundle infoBundle=getIntent().getExtras();
try {
dataBean = (DataBean)bytes2Object(infoBundle.getByteArray("Obj_byte_array"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Method to get objects from byte arrays:
/**
* Converting byte arrays to objects
*/
static public Object bytes2Object( byte raw[] )
throws IOException, ClassNotFoundException {
ByteArrayInputStream bais = new ByteArrayInputStream( raw );
ObjectInputStream ois = new ObjectInputStream( bais );
Object o = ois.readObject();
return o;
}
Hope this will help to other buddies.
Another difference not pointed out is that giving the struct a name (i.e. struct myStruct) also enables you to provide forward declarations of the struct. So in some other file, you could write:
struct myStruct;
void doit(struct myStruct *ptr);
without having to have access to the definition. What I recommend is you combine your two examples:
typedef struct myStruct{
int one;
int two;
} myStruct;
This gives you the convenience of the more concise typedef name but still allows you to use the full struct name if you need.
In Content page you can access the label and set the text such as
Here 'lblStatus' is the your master page label ID
Label lblMasterStatus = (Label)Master.FindControl("lblStatus"); lblMasterStatus.Text = "Meaasage from content page";
Seems like it's quite a popular question, so I will try to make my humble contribution.
The code below is Swift 4 solution for no-storyboard setup. It utilizes some approaches from previous answers, therefore it prevents Auto Layout warning caused on device rotation.
I am sorry if code samples are a bit long. I want to provide an "easy-to-use" solution fully hosted by StackOverflow. If you have any suggestions to the post - please, share the idea and I will update it accordingly.
Two classes: ViewController.swift
and MultilineLabelCell.swift
- Cell containing single UILabel
.
MultilineLabelCell.swift
import UIKit
class MultilineLabelCell: UICollectionViewCell {
static let reuseId = "MultilineLabelCellReuseId"
private let label: UILabel = UILabel(frame: .zero)
override init(frame: CGRect) {
super.init(frame: frame)
layer.borderColor = UIColor.red.cgColor
layer.borderWidth = 1.0
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
let labelInset = UIEdgeInsets(top: 10, left: 10, bottom: -10, right: -10)
contentView.addSubview(label)
label.translatesAutoresizingMaskIntoConstraints = false
label.topAnchor.constraint(equalTo: contentView.layoutMarginsGuide.topAnchor, constant: labelInset.top).isActive = true
label.leadingAnchor.constraint(equalTo: contentView.layoutMarginsGuide.leadingAnchor, constant: labelInset.left).isActive = true
label.trailingAnchor.constraint(equalTo: contentView.layoutMarginsGuide.trailingAnchor, constant: labelInset.right).isActive = true
label.bottomAnchor.constraint(equalTo: contentView.layoutMarginsGuide.bottomAnchor, constant: labelInset.bottom).isActive = true
label.layer.borderColor = UIColor.black.cgColor
label.layer.borderWidth = 1.0
}
required init?(coder aDecoder: NSCoder) {
fatalError("Storyboards are quicker, easier, more seductive. Not stronger then Code.")
}
func configure(text: String?) {
label.text = text
}
override func preferredLayoutAttributesFitting(_ layoutAttributes: UICollectionViewLayoutAttributes) -> UICollectionViewLayoutAttributes {
label.preferredMaxLayoutWidth = layoutAttributes.size.width - contentView.layoutMargins.left - contentView.layoutMargins.left
layoutAttributes.bounds.size.height = systemLayoutSizeFitting(UIView.layoutFittingCompressedSize).height
return layoutAttributes
}
}
ViewController.swift
import UIKit
let samuelQuotes = [
"Samuel says",
"Add different length strings here for better testing"
]
class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {
private(set) var collectionView: UICollectionView
// Initializers
init() {
// Create new `UICollectionView` and set `UICollectionViewFlowLayout` as its layout
collectionView = UICollectionView(frame: .zero, collectionViewLayout: UICollectionViewFlowLayout())
super.init(nibName: nil, bundle: nil)
}
required init?(coder aDecoder: NSCoder) {
// Create new `UICollectionView` and set `UICollectionViewFlowLayout` as its layout
collectionView = UICollectionView(frame: .zero, collectionViewLayout: UICollectionViewFlowLayout())
super.init(coder: aDecoder)
}
override func viewDidLoad() {
super.viewDidLoad()
title = "Dynamic size sample"
// Register Cells
collectionView.register(MultilineLabelCell.self, forCellWithReuseIdentifier: MultilineLabelCell.reuseId)
// Add `coolectionView` to display hierarchy and setup its appearance
view.addSubview(collectionView)
collectionView.backgroundColor = .white
collectionView.contentInsetAdjustmentBehavior = .always
collectionView.contentInset = UIEdgeInsets(top: 10, left: 10, bottom: 10, right: 10)
// Setup Autolayout constraints
collectionView.translatesAutoresizingMaskIntoConstraints = false
collectionView.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: 0).isActive = true
collectionView.leftAnchor.constraint(equalTo: view.leftAnchor, constant: 0).isActive = true
collectionView.topAnchor.constraint(equalTo: view.topAnchor, constant: 0).isActive = true
collectionView.rightAnchor.constraint(equalTo: view.rightAnchor, constant: 0).isActive = true
// Setup `dataSource` and `delegate`
collectionView.dataSource = self
collectionView.delegate = self
(collectionView.collectionViewLayout as! UICollectionViewFlowLayout).estimatedItemSize = UICollectionViewFlowLayout.automaticSize
(collectionView.collectionViewLayout as! UICollectionViewFlowLayout).sectionInsetReference = .fromLayoutMargins
}
// MARK: - UICollectionViewDataSource -
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: MultilineLabelCell.reuseId, for: indexPath) as! MultilineLabelCell
cell.configure(text: samuelQuotes[indexPath.row])
return cell
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return samuelQuotes.count
}
// MARK: - UICollectionViewDelegateFlowLayout -
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
let sectionInset = (collectionViewLayout as! UICollectionViewFlowLayout).sectionInset
let referenceHeight: CGFloat = 100 // Approximate height of your cell
let referenceWidth = collectionView.safeAreaLayoutGuide.layoutFrame.width
- sectionInset.left
- sectionInset.right
- collectionView.contentInset.left
- collectionView.contentInset.right
return CGSize(width: referenceWidth, height: referenceHeight)
}
}
To run this sample create new Xcode project, create corresponding files and replace AppDelegate
contents with the following code:
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var navigationController: UINavigationController?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
window = UIWindow(frame: UIScreen.main.bounds)
if let window = window {
let vc = ViewController()
navigationController = UINavigationController(rootViewController: vc)
window.rootViewController = navigationController
window.makeKeyAndVisible()
}
return true
}
}
You could do something like this: Use ng-pattern with the RegExp "/^[0-9]+$/" that means only integer numbers are valid.
<form novalidate name="form">
<input type="text" data-ng-model="age" id="age" name="age" ng-pattern="/^[0-9]+$/">
<span ng-show="form.age.$error.pattern">The value is not a valid integer</span>
</form>
The correct way to implement your code is
y="HELLO"
val=$(echo "$y" | tr '[:upper:]' '[:lower:]')
string="$val world"
This uses $(...)
notation to capture the output of the command in a variable. Note also the quotation marks around the string
variable -- you need them there to indicate that $val
and world
are a single thing to be assigned to string
.
If you have bash
4.0 or higher, a more efficient & elegant way to do it is to use bash
builtin string manipulation:
y="HELLO"
string="${y,,} world"
You can do it like this:
var myApp = angular.module('myApp', [])
.controller('Ctrl', ['$scope', function($scope) {
$scope.aaa = 3432
}])
.directive('test', function () {
return {
link: function (scope, elm, attr) {
var look = elm.children('#findme').addClass("addedclass");
console.log(look);
}
};
});
<div ng-app="myApp" ng-controller="Ctrl">
<div test>TEST Div
<div id="findme">{{aaa}}</div>
</div>
</div>
You can use the COALESCE function to automatically return null values as 0. Syntax is as shown below:
SELECT COALESCE(total_amount, 0) from #Temp1
Personally (and given what I know, i.e., Java and axis), I'd generate a Java data model from the .xsd files (Axis 2 can do this), and then add an interface to describe my web service that uses that model, and then generate a WSDL from that interface.
Because .NET has all these features as well, it must be possible to do all this in that ecosystem as well.
I believe this is the simplest way of putting all what it is on the screen into a file. It is a native PS CmdLet so you don't have to change anything in yout script
Start-Transcript -Path Computer.log
Write-Host "everything will end up in Computer.log"
Stop-Transcript
if you want to filter the tuples you can use on this way:
select distinct (case a > b then (a,b) else (b,a) end) from pairs
the good stuff is you don't have to use group by.
