You are going to need to call the SmsManager
class. You are probably going to need to use the STATUS_ON_ICC_READ
constant and maybe put what you get there into your apps local db so that you can keep track of what you have already read vs the new stuff for your app to parse through.
BUT bear in mind that you have to declare the use of the class in your manifest, so users will see that you have access to their SMS called out in the permissions dialogue they get when they install. Seeing SMS access is unusual and could put some users off. Good luck.
This one seems a bit more complete: https://github.com/dump247/angular.tree
If you're dealing with character encodings other than UTF-16, you shouldn't be using java.lang.String
or the char
primitive -- you should only be using byte[]
arrays or ByteBuffer
objects. Then, you can use java.nio.charset.Charset
to convert between encodings:
Charset utf8charset = Charset.forName("UTF-8");
Charset iso88591charset = Charset.forName("ISO-8859-1");
ByteBuffer inputBuffer = ByteBuffer.wrap(new byte[]{(byte)0xC3, (byte)0xA2});
// decode UTF-8
CharBuffer data = utf8charset.decode(inputBuffer);
// encode ISO-8559-1
ByteBuffer outputBuffer = iso88591charset.encode(data);
byte[] outputData = outputBuffer.array();
You want rows where that condition is true so you need a comma:
data[data$Ozone > 14, ]
Focus
sets the input focus, so setting it to the form won't work because forms don't accept input. Try setting the form's ActiveControl
property to a different control. You could also use Select
to select a specific control or SelectNextControl
to select the next control in the tab order.
Check out this snippet:
Private Sub openDialog()
Dim fd As Office.FileDialog
Set fd = Application.FileDialog(msoFileDialogFilePicker)
With fd
.AllowMultiSelect = False
' Set the title of the dialog box.
.Title = "Please select the file."
' Clear out the current filters, and add our own.
.Filters.Clear
.Filters.Add "Excel 2003", "*.xls"
.Filters.Add "All Files", "*.*"
' Show the dialog box. If the .Show method returns True, the
' user picked at least one file. If the .Show method returns
' False, the user clicked Cancel.
If .Show = True Then
txtFileName = .SelectedItems(1) 'replace txtFileName with your textbox
End If
End With
End Sub
I think this is what you are asking for.
They way I did it was by selecting all of the data
select * from myTable
and then right-clicking on the result set and chose "Save results as..." a csv file.
Opening the csv file in Notepad++ I saw the LF characters not visible in SQL Server result set.
regular expression starts with number->'^[0-9]'
Pattern pattern = Pattern.compile('^[0-9]');
Matcher matcher = pattern.matcher(String);
if(matcher.find()){
System.out.println("true");
}
Even though this is an old question, I had to do something similar today but I prefer JSTL:
<c:forEach var="par" items="${paramValues}">
<c:if test="${fn:startsWith(par.key, 'question')}">
${par.key} = ${par.value[0]}; //whatever
</c:if>
</c:forEach>
The Python ValueError:
ValueError: setting an array element with a sequence.
Means exactly what it says, you're trying to cram a sequence of numbers into a single number slot. It can be thrown under various circumstances.
1. When you pass a python tuple or list to be interpreted as a numpy array element:
import numpy
numpy.array([1,2,3]) #good
numpy.array([1, (2,3)]) #Fail, can't convert a tuple into a numpy
#array element
numpy.mean([5,(6+7)]) #good
numpy.mean([5,tuple(range(2))]) #Fail, can't convert a tuple into a numpy
#array element
def foo():
return 3
numpy.array([2, foo()]) #good
def foo():
return [3,4]
numpy.array([2, foo()]) #Fail, can't convert a list into a numpy
#array element
2. By trying to cram a numpy array length > 1 into a numpy array element:
x = np.array([1,2,3])
x[0] = np.array([4]) #good
x = np.array([1,2,3])
x[0] = np.array([4,5]) #Fail, can't convert the numpy array to fit
#into a numpy array element
A numpy array is being created, and numpy doesn't know how to cram multivalued tuples or arrays into single element slots. It expects whatever you give it to evaluate to a single number, if it doesn't, Numpy responds that it doesn't know how to set an array element with a sequence.
You can use this:
select
table_name,column_name,referenced_table_name,referenced_column_name
from
information_schema.key_column_usage
where
referenced_table_name is not null
and table_schema = 'my_database'
and table_name = 'my_table'
Or for better formatted output use this:
select
concat(table_name, '.', column_name) as 'foreign key',
concat(referenced_table_name, '.', referenced_column_name) as 'references'
from
information_schema.key_column_usage
where
referenced_table_name is not null
and table_schema = 'my_database'
and table_name = 'my_table'
Use the PercentRelativeLayout or PercentFrameLayout from the Percent Supoort Library

I want to propose other one with using $.each:
We may to declare ajax function like:
function ajaxFn(someData) {
this.someData = someData;
var that = this;
return function () {
var promise = $.Deferred();
$.ajax({
method: "POST",
url: "url",
data: that.someData,
success: function(data) {
promise.resolve(data);
},
error: function(data) {
promise.reject(data);
}
})
return promise;
}
}
Part of code where we creating array of functions with ajax to send:
var arrayOfFn = [];
for (var i = 0; i < someDataArray.length; i++) {
var ajaxFnForArray = new ajaxFn(someDataArray[i]);
arrayOfFn.push(ajaxFnForArray);
}
And calling functions with sending ajax:
$.when(
$.each(arrayOfFn, function(index, value) {
value.call()
})
).then(function() {
alert("Cheer!");
}
)
I like using the IsNullOrEmpty method of the class String like so...
input = InputBox("Text:")
If String.IsNullOrEmpty(input) Then
' Cancelled, or empty
Else
' Normal
End If
Use the FULL path to the folder in your If Not Exist code. Then you won't even have to CD anymore:

Unfortunately as I am forced to use a windows server I have been unable to get openssl working in the way the above answer suggests.
However I was able to get a similar program called stunnel (which can be downloaded from here) to work. I got the idea from www.tech-and-dev.com but I had to change the instructions slightly. Here is what I did:
stunnel.conf
config file, which in my case I installed to C:\Program Files (x86)\stunnel
Then, you need to open this file in a text viewer such as notepad. Look for [gmail-smtp]
and remove the semicolon on the client line below (in the stunnel.conf file, every line that starts with a semicolon is a comment). You should end up with something like:
[gmail-smtp]
client = yes
accept = 127.0.0.1:25
connect = smtp.gmail.com:465
Once you have done this save the stunnel.conf
file and reload the config (to do this use the stunnel GUI program, and click on configuration=>Reload).
Now you should be ready to send email in the windows telnet client!
Go to Start=>run=>cmd.
Once cmd is open type in the following and press Enter:
telnet localhost 25
You should then see something similar to the following:
220 mx.google.com ESMTP f14sm1400408wbe.2
You will then need to reply by typing the following and pressing enter:
helo google
This should give you the following response:
250 mx.google.com at your service
If you get this you then need to type the following and press enter:
ehlo google
This should then give you the following response:
250-mx.google.com at your service, [212.28.228.49]
250-SIZE 35651584
250-8BITMIME
250-AUTH LOGIN PLAIN XOAUTH
250 ENHANCEDSTATUSCODES
Now you should be ready to authenticate with your Gmail details. To do this type the following and press enter:
AUTH LOGIN
This should then give you the following response:
334 VXNlcm5hbWU6
This means that we are ready to authenticate by using our gmail address and password.
However since this is an encrypted session, we're going to have to send the email and password encoded in base64. To encode your email and password, you can use a converter program or an online website to encode it (for example base64 or search on google for ’base64 online encoding’). I reccomend you do not touch the cmd/telnet session again until you have done this.
For example [email protected] would become dGVzdEBnbWFpbC5jb20= and password would become cGFzc3dvcmQ=
Once you have done this copy and paste your converted base64 username into the cmd/telnet session and press enter. This should give you following response:
334 UGFzc3dvcmQ6
Now copy and paste your converted base64 password into the cmd/telnet session and press enter. This should give you following response if both login credentials are correct:
235 2.7.0 Accepted
You should now enter the sender email (should be the same as the username) in the following format and press enter:
MAIL FROM:<[email protected]>
This should give you the following response:
250 2.1.0 OK x23sm1104292weq.10
You can now enter the recipient email address in a similar format and press enter:
RCPT TO:<[email protected]>
This should give you the following response:
250 2.1.5 OK x23sm1104292weq.10
Now you will need to type the following and press enter:
DATA
Which should give you the following response:
354 Go ahead x23sm1104292weq.10
Now we can start to compose the message! To do this enter your message in the following format (Tip: do this in notepad and copy the entire message into the cmd/telnet session):
From: Test <[email protected]>
To: Me <[email protected]>
Subject: Testing email from telnet
This is the body
Adding more lines to the body message.
When you have finished the email enter a dot:
.
This should give you the following response:
250 2.0.0 OK 1288307376 x23sm1104292weq.10
And now you need to end your session by typing the following and pressing enter:
QUIT
This should give you the following response:
221 2.0.0 closing connection x23sm1104292weq.10
Connection to host lost.
And your email should now be in the recipient’s mailbox!
You can use js and add a class in html to maintain the standard of conditional comments:
var ua = navigator.userAgent,
doc = document.documentElement;
if ((ua.match(/MSIE 10.0/i))) {
doc.className = doc.className + " ie10";
} else if((ua.match(/rv:11.0/i))){
doc.className = doc.className + " ie11";
}
Or use a lib like bowser:
Or modernizr for feature detection:
float(str(round(answer, 2)))
float(str(round(0.0556781255, 2)))
Create a HttpRequestMessage
, set the Method to GET
, set your headers and then use SendAsync
instead of GetAsync
.
var client = new HttpClient();
var request = new HttpRequestMessage() {
RequestUri = new Uri("http://www.someURI.com"),
Method = HttpMethod.Get,
};
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("text/plain"));
var task = client.SendAsync(request)
.ContinueWith((taskwithmsg) =>
{
var response = taskwithmsg.Result;
var jsonTask = response.Content.ReadAsAsync<JsonObject>();
jsonTask.Wait();
var jsonObject = jsonTask.Result;
});
task.Wait();
try to use proper tags for HTML5 controls Like for Number(integers)
<input type='number' min='0' pattern ='[0-9]*' step='1'/>
for Decimals or float
<input type='number' min='0' step='Any'/>
step='Any' Without this you cannot submit your form entering any decimal or float value like 3.5 or 4.6 in the above field.
Try fixing the pattern , type for HTML5 controls to fix this issue.
A lot of good answers already, but let me see if I can give you another viewpoint.
Simplifying things by quite a bit, you can view a framework as an application that is complete except for the actual functionality. You plug in the functionality and PRESTO! you have an application.
Consider, say, a GUI framework. The framework contains everything you need to make an application. Indeed you can often trivially make a minimal application with very few lines of source that does absolutely nothing -- but it does give you window management, sub-window management, menus, button bars, etc. That's the framework side of things. By adding your application functionality and "plugging it in" to the right places in the framework you turn this empty app that does nothing more than window management, etc. into a real, full-blown application.
There are similar types of frameworks for web apps, for server-side apps, etc. In each case the framework provides the bulk of the tedious, repetitive code (hopefully) while you provide the actual problem domain functionality. (This is the ideal. In reality, of course, the success of the framework is highly variable.)
I stress again that this is the simplified view of what a framework is. I'm not using scary terms like "Inversion of Control" and the like although most frameworks have such scary concepts built-in. Since you're a beginner, I thought I'd spare you the jargon and go with an easy simile.

Basically what I did here is make a page all in one php file where when you enter the password if its right it will hide the password screen and bring the stuff that protected forward. and then heres the css which is a crucial part because it makes the classes that hide and show the different parts of the page.
/*PHP CONTENT STARTS HERE*/
.hider {
visibility:hidden;
display:none;
}
.shower {
visibility:visible;
}
#phplogger {
background-color:#333;
color:blue;
position:absolute;
height:100%;
width:100%;
margin:0;
top:0;
bottom:0;
}
/*PHP CONTENT ENDS HERE*/
The proper interval to get one second is 1000. The Interval
property is the time between ticks in milliseconds:
So, it's not the interval that you set that is wrong. Check the rest of your code for something like changing the interval of the timer, or binding the Tick
event multiple times.
Besides executeUpdate() on the parentheses, you must also add a variable to use an SQL statement.
For example:
PreparedStatement pst = connection.prepareStatement(sql);
int numRowsChanged = pst.executeUpdate(sql);
use the following code,
iv.setImageResource(getResources().getIdentifier("apple", "drawable", getPackageName()));
I ran into the same problem a couple of years ago and funded the development of a plugin to help me in my work. I've released the plugin as open-source so others can benefit from it as well, and you can grab it on Github: https://github.com/eqcss/eqcss
There are a few ways we could apply different responsive styles based on what we can know about an element on the page. Here are a few element queries that the EQCSS plugin will let you write in CSS:
@element 'div' and (condition) {
$this {
/* Do something to the 'div' that meets the condition */
}
.other {
/* Also apply this CSS to .other when 'div' meets this condition */
}
}
So what conditions are supported for responsive styles with EQCSS?
px
%
px
%
px
%
px
%
Inside EQCSS element queries you can also use three special selectors that allow you to more specifically apply your styles:
$this
(the element(s) matching the query)$parent
(the parent element(s) of the element(s) matching the query)$root
(the root element of the document, <html>
)Element queries allow you to compose your layout out of individually responsive design modules, each with a bit of 'self-awareness' of how they are being displayed on the page.
With EQCSS you can design one widget to look good from 150px wide all the way up to 1000px wide, then you can confidently drop that widget into any sidebar in any page using any template (on any site) and
Use like this,
HTML:
<input type="text" disabled="disabled" class="inputDisabled" value="">
<div id="edit">edit</div>
JS:
$('#edit').click(function(){ // click to
$('.inputDisabled').attr('disabled',false); // removing disabled in this class
});
If you want to replace only multiple spaces in a string, for Example: "this string have lots of space . "
And you expect the answer to be
"this string have lots of space"
, you can use the following solution:
$strng = "this string have lots of space . ";
$strng = trim(preg_replace('/\s+/',' ', $strng));
echo $strng;
In order to do this without FuncAnimation (eg you want to execute other parts of the code while the plot is being produced or you want to be updating several plots at the same time), calling draw
alone does not produce the plot (at least with the qt backend).
The following works for me:
import matplotlib.pyplot as plt
plt.ion()
class DynamicUpdate():
#Suppose we know the x range
min_x = 0
max_x = 10
def on_launch(self):
#Set up plot
self.figure, self.ax = plt.subplots()
self.lines, = self.ax.plot([],[], 'o')
#Autoscale on unknown axis and known lims on the other
self.ax.set_autoscaley_on(True)
self.ax.set_xlim(self.min_x, self.max_x)
#Other stuff
self.ax.grid()
...
def on_running(self, xdata, ydata):
#Update data (with the new _and_ the old points)
self.lines.set_xdata(xdata)
self.lines.set_ydata(ydata)
#Need both of these in order to rescale
self.ax.relim()
self.ax.autoscale_view()
#We need to draw *and* flush
self.figure.canvas.draw()
self.figure.canvas.flush_events()
#Example
def __call__(self):
import numpy as np
import time
self.on_launch()
xdata = []
ydata = []
for x in np.arange(0,10,0.5):
xdata.append(x)
ydata.append(np.exp(-x**2)+10*np.exp(-(x-7)**2))
self.on_running(xdata, ydata)
time.sleep(1)
return xdata, ydata
d = DynamicUpdate()
d()
Here are 3 more suggestions or techniques:
You can add an additional field to tell if the struct has been populated or it is empty. I intentionally named it ready
and not empty
because the zero value of a bool
is false
, so if you create a new struct like Session{}
its ready
field will be automatically false
and it will tell you the truth: that the struct is not-yet ready (it's empty).
type Session struct {
ready bool
playerId string
beehive string
timestamp time.Time
}
When you initialize the struct, you have to set ready
to true
. Your isEmpty()
method isn't needed anymore (although you can create one if you want to) because you can just test the ready
field itself.
var s Session
if !s.ready {
// do stuff (populate s)
}
Significance of this one additional bool
field increases as the struct grows bigger or if it contains fields which are not comparable (e.g. slice, map
and function values).
This is similar to the previous suggestion, but it uses the zero value of an existing field which is considered invalid when the struct is not empty. Usability of this is implementation dependant.
For example if in your example your playerId
cannot be the empty string
""
, you can use it to test if your struct is empty like this:
var s Session
if s.playerId == "" {
// do stuff (populate s, give proper value to playerId)
}
In this case it's worth incorporating this check into an isEmpty()
method because this check is implementation dependant:
func (s Session) isEmpty() bool {
return s.playerId == ""
}
And using it:
if s.isEmpty() {
// do stuff (populate s, give proper value to playerId)
}
The second suggestion is to use a Pointer to your struct: *Session
. Pointers can have nil
values, so you can test for it:
var s *Session
if s == nil {
s = new(Session)
// do stuff (populate s)
}
map()
doesn't return a list, it returns a map
object.
You need to call list(map)
if you want it to be a list again.
Even better,
from itertools import imap
payIntList = list(imap(int, payList))
Won't take up a bunch of memory creating an intermediate object, it will just pass the ints
out as it creates them.
Also, you can do if choice.lower() == 'n':
so you don't have to do it twice.
Python supports +=
: you can do payIntList[i] += 1000
and numElements += 1
if you want.
If you really want to be tricky:
from itertools import count
for numElements in count(1):
payList.append(raw_input("Enter the pay amount: "))
if raw_input("Do you wish to continue(y/n)?").lower() == 'n':
break
and / or
for payInt in payIntList:
payInt += 1000
print payInt
Also, four spaces is the standard indent amount in Python.
If you write a comment in a line with a code, you must write a comment, leaving 2 spaces before the # sign and 1 space before the # sign
print("Hello World") # printing
If you write a comment on a new line, you must write a comment, leaving 1 space kn in the # sign
# single line comment
To write comments longer than 1 line, you use 3 quotes
"""
This is a comment
written in
more than just one line
"""
If you run pub build --mode=debug
the build directory contains the application without symlinks. The Dart code should be retained when --mode=debug
is used.
Here is some discussion going on about this topic too Dart and it's place in Rails Assets Pipeline
SwiftRichString
works perfect! You can use +
to concatenate two attributed string
You can make sure that the object in question is stringified before passing it to parse function by simply using JSON.stringify()
.
Updated your line below,
JSON.parse(JSON.stringify({"balance":0,"count":0,"time":1323973673061,"firstname":"howard","userId":5383,"localid":1,"freeExpiration":0,"status":false}));
or if you have JSON stored in some variable:
JSON.parse(JSON.stringify(yourJSONobject));
Here is an example:
MySqlConnection con = new MySqlConnection(
"Server=ServerName;Database=DataBaseName;UID=username;Password=password");
MySqlCommand cmd = new MySqlCommand(
" INSERT Into Test (lat, long) VALUES ('"+OSGconv.deciLat+"','"+
OSGconv.deciLon+"')", con);
con.Open();
cmd.ExecuteNonQuery();
con.Close();
If you an macos, rename lib folder lib/python3.7/site-packages/crypto
to lib/python3.7/site-packages/Crypto
Just had a similar issue
Resolved it by checking in httpd.conf
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
#
AllowOverride All <--- make sure this is not set to "None"
It is worth bearing in mind I tried (from Mark's answer) the "put garbage in the .htaccess" which did give a server error - but even though it was being read, it wasn't being acted on due to no overrides allowed.
Do you have access to the SQL Server you are querying? Can you see a Table or View called dbo.Projects there? If not, that would be a good place to look.
Linq to SQL creates an object map between the database and the application. If your new DLL that you're deploying doesn't match with the database anymore, then this is the sort of error you'd expect to get.
Do you perhaps have different database schemas between your development environment and the deployment environment?
If you need to know if a word exists in a string you can use this. As it is not clear from your question if you just want to know if the variable is a string or not. Where 'word' is the word you are searching in the string.
if (strpos($a,'word') !== false) {
echo 'true';
}
or use the is_string method. Whichs returns true or false on the given variable.
<?php
$a = '';
is_string($a);
?>
set -a
. ./env.txt
set +a
If env.txt
is like:
VAR1=1
VAR2=2
VAR3=3
...
Explanations -a is equivalent to allexport. In other words, every variable assignment in the shell is exported into the environment (to be used by multiple child processes). More information can be found in the Set builtin documentation:
-a Each variable or function that is created or modified is given the export attribute and marked for export to the environment of subsequent commands.
Using ‘+’ rather than ‘-’ causes these options to be turned off. The options can also be used upon invocation of the shell. The current set of options may be found in $-.
You remove the original image here:
newImg.animate(css, SPEED, function() {
img.remove();
newImg.removeClass('morpher');
(callback || function() {})();
});
And all that's left behind is newImg
. Then you reset link references the image using #rocket
:
$("#rocket").attr('src', ...
But your newImg
doesn't have an id
attribute let alone an id
of rocket
.
To fix this, you need to remove img
and then set the id
attribute of newImg
to rocket
:
newImg.animate(css, SPEED, function() {
var old_id = img.attr('id');
img.remove();
newImg.attr('id', old_id);
newImg.removeClass('morpher');
(callback || function() {})();
});
And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/
UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:
$("#resetlink").click(function(){
clearInterval(timerRocket);
$("#wrapper").css('top', '250px');
$('.throbber, .morpher').remove(); // Clear out the new stuff.
$("#rocket").show(); // Bring the original back.
});
And in the newImg.load
function, grab the images original size:
var orig = {
width: img.width(),
height: img.height()

And finally, the callback for finishing the morphing animation becomes this:
newImg.animate(css, SPEED, function() {
img.css(orig).hide();
(callback || function() {})();
});

The leaking of $('.throbber, .morpher')
outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.
Java 8 lambda expressions. Both fast and simple.
boolean allLetters = someString.chars().allMatch(Character::isLetter);
This one, from kristopherjohnson is heaps better:
Less lines of code
static string PrettyXml(string xml)
{
var stringBuilder = new StringBuilder();
var element = XElement.Parse(xml);
var settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
settings.Indent = true;
settings.NewLineOnAttributes = true;
using (var xmlWriter = XmlWriter.Create(stringBuilder, settings))
{
element.Save(xmlWriter);
}
return stringBuilder.ToString();
}
It's probably best to skip hidden files and folders, such as .git.
So instead of using find
, if your bash
version is recent enough or if you're using zsh
, just do:
dos2unix **
Note that for Bash, this will require:
shopt -s globstar
....but this is a useful enough feature that you should honestly just put it in your .bashrc
anyway.
If you don't want to skip hidden files and folders, but you still don't want to mess with find
(and I wouldn't blame you), you can provide a second recursive-glob argument to match only hidden entries:
dos2unix ** **/.*
Note that in both cases, the glob will expand to include directories, so you will see the following warning (potentially many times over): Skipping <dir>, not a regular file.
It happens because with navbar-fixed-top
class the navbar gets the position:fixed
. This in turns take the navbar out of the document flow leaving the body to take up the space behind the navbar.
You need to apply padding-top
or margin-top
to your container
, based on your requirements with values >= 50px
. (or play around with different values)
The basic bootstrap navbar takes height around 40px
. So if you give a padding-top
or margin-top
of 50px
or more, you will always have that breathing space between your container and the navbar.
Use a collection that is a static property of your Car
class.
Every time you create a new instance of a Car
, store the reference in this collection.
To destroy all Car
s, just set all items to null
.
FWIW I had this same issue. Turned out my xsi:schemaLocation entries were incorrect, so I went to the official docs and pasted theirs into mine:
http://docs.spring.io/spring/docs/current/spring-framework-reference/html/transaction.html section 16.5.6
I had to add a couple more but that was ok. Next up is to find out why this fixed the problem...
You can just specify the python version when running a program:

python filename.py
for python 3:
python3 filename.py
Use command "php artisan migrate:rollback --step=1" to rollback migration to 1 step back.

I use laravel 7.x and I used this as a workaround:->get()->pluck('id')->toArray();
it gives back an array of ids [50,2,3]
and this is the whole query I used:
$article_tags = DB::table('tags')
->join('taggables', function ($join) use ($id) {
$join->on('tags.id', '=', 'taggables.tag_id');
$join->where([
['taggable_id', '=', $id],
['taggable_type','=','article']
]);
})->select('tags.id')->get()->pluck('id')->toArray();
It's considered poor form. Use a list comprehension instead, with slice assignment if you need to retain existing references to the list.
a = [1, 3, 5]
b = a
a[:] = [x + 2 for x in a]
print(b)
Check this out this may work: (in kotlin)
toolBar.menu.getItem(indexNumber).setIcon(R.drawable.ic_myIcon)
I think this will cover any possible scenario for what is in O10:
=IF(ISBLANK(O10),"",IF(O10<TODAY(),IF(TODAY()-O10<>1,CONCATENATE("Due in ",TEXT(TODAY()-O10,"d")," days"),CONCATENATE("Due in ",TEXT(TODAY()-O10,"d")," day")),IF(O10=TODAY(),"Due Today","Overdue")))
For Dates that are before Today, it will tell you how many days the item is due in. If O10 = Today then it will say "Due Today". Anything past Today and it will read overdue. Lastly, if it is blank, the cell will also appear blank. Let me know what you think!
Maybe I'm missing something but you want to wind up with a String that looks like this, "999897969594...543210"
, correct?
StringBuilder sb = new StringBuilder();
for(int i=99;i>=0;i--){
sb.append(String.valueOf(i));
}
Is this something you are going to be doing a lot? If so, you may want to consider a different data structure. Grep is going to search the entire array every time and for a large array could be quite costly. If speed is an issue then you may want to consider using a Hash instead.
In your example, the key would be the number and the value would be the count of elements of that number.
You could add an event handler to your input like so:
document.getElementById('addLinks').onkeypress=function(e){
if(e.keyCode==13){
document.getElementById('linkadd').click();
}
}
I can imagine following advantages of having a class method defined as static one:
remaining advantages are probably marginal if present at all:
Here a version that uses shuffle and streams
List<Direction> letters = Arrays.asList(Direction.values());
Collections.shuffle(letters);
return letters.stream().findFirst().get();
The main difference is w+
truncate the file to zero length if it exists or create a new file if it doesn't. While r+
neither deletes the content nor create a new file if it doesn't exist.
Try these codes and you will understand:
#include <stdio.h>
int main()
{
FILE *fp;
fp = fopen("test.txt", "w+");
fprintf(fp, "This is testing for fprintf...\n");
fputs("This is testing for fputs...\n", fp);
fclose(fp);
}
and then this
#include <stdio.h>
int main()
{
FILE *fp;
fp = fopen("test.txt", "w+");
fclose(fp);
}
Then open the file test.txt
and see the what happens. You will see that all data written by the first program has been erased.
Repeat this for r+
and see the result. Hope you will understand.
BEWARE OF parse_requirements
BEHAVIOUR!
Please note that pip.req.parse_requirements
will change underscores to dashes. This was enraging me for a few days before I discovered it. Example demonstrating:
from pip.req import parse_requirements # tested with v.1.4.1
reqs = '''
example_with_underscores
example-with-dashes
'''
with open('requirements.txt', 'w') as f:
f.write(reqs)
req_deps = parse_requirements('requirements.txt')
result = [str(ir.req) for ir in req_deps if ir.req is not None]
print result
produces
['example-with-underscores', 'example-with-dashes']
Try:
from p in db.Products
where !theBadCategories.Contains(p.Category)
select p;
What's the SQL query you want to translate into a Linq query?
From:
it could be:
.html()
In an HTML document, .html()
can be used to get the contents of any element.
.text()
Unlike the .html()
method, .text()
can be used in both XML and HTML documents. The result of the .text()
method is a string containing the combined text of all matched elements.
.val()
The .val()
method is primarily used to get the values of form elements such as input
, select
and textarea
. When called on an empty collection, it returns undefined
.
int uniqueId = 0;
int getUniqueId()
{
return uniqueId++;
}
Add synchronized
if you want it to be thread safe.
I prefer to add some checking of the fields, e.g. so you can catch errors like when you get invalid json, or not the json you were expecting, so I used namedtuples:
from collections import namedtuple
payload = namedtuple('payload', ['action', 'method', 'data'])
def deserialize_payload(json):
kwargs = dict([(field, json[field]) for field in payload._fields])
return payload(**kwargs)
this will let give you nice errors when the json you are parsing does not match the thing you want it to parse
>>> json = {"action":"print","method":"onData","data":"Madan Mohan"}
>>> deserialize_payload(json)
payload(action='print', method='onData', data='Madan Mohan')
>>> badjson = {"error":"404","info":"page not found"}
>>> deserialize_payload(badjson)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in deserialize_payload
KeyError: 'action'
if you want to parse nested relations, e.g. '{"parent":{"child":{"name":"henry"}}}'
you can still use the namedtuples, and even a more reusable function
Person = namedtuple("Person", ['parent'])
Parent = namedtuple("Parent", ['child'])
Child = namedtuple('Child', ['name'])
def deserialize_json_to_namedtuple(json, namedtuple):
return namedtuple(**dict([(field, json[field]) for field in namedtuple._fields]))
def deserialize_person(json):
json['parent']['child'] = deserialize_json_to_namedtuple(json['parent']['child'], Child)
json['parent'] = deserialize_json_to_namedtuple(json['parent'], Parent)
person = deserialize_json_to_namedtuple(json, Person)
return person
giving you
>>> deserialize_person({"parent":{"child":{"name":"henry"}}})
Person(parent=Parent(child=Child(name='henry')))
>>> deserialize_person({"error":"404","info":"page not found"})
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in deserialize_person
KeyError: 'parent'
Another solution:
public static MemoryStream GenerateStreamFromString(string value)
{
return new MemoryStream(Encoding.UTF8.GetBytes(value ?? ""));
}
Below is my solution
int[] A = {1,2,3};
Arrays.sort(A);
Set<Integer> positiveSet = new HashSet<>();
for(int a: A) {
if(a>0) {
positiveSet.add(a);
}
}
for(int a: A) {
int res = a+1;
if(!positiveSet.contains(res)) {
System.out.println("result : "+res);
break;
}
}
Here is my config and it works fine for PHP API:

You're declaring a virtual

Either define it or declare it as:
virtual void calculateCredits() = 0;
Or simply:
virtual void calculateCredits() { };

All the answers already covered most of the things but I will add my 5 cents. In short reverting a merge commit is quite simple:
git revert -m 1 <commit-hash>
If you have permission you can push it directly to the "master" branch otherwise simply push it to your "revert" branch and create pull request.
You might find more useful info on this subject here: https://itcodehub.blogspot.com/2019/06/how-to-revert-merge-in-git.html
In Java 9 there is a new way:
public static void showTrace() {
List<StackFrame> frames =
StackWalker.getInstance( Option.RETAIN_CLASS_REFERENCE )
.walk( stream -> stream.collect( Collectors.toList() ) );
for ( StackFrame stackFrame : frames )
System.out.println( stackFrame );
}

If you use jQuery, this is what it uses for parameterizing the options of a GET XHR request:
$.param( obj )
You can create a registry entry in "HKCU\Software\Microsoft\Windows\CurrentVersion\Run", just be aware that it may work differently on Vista. Your setting might get "virtualized" because of UAC.
private static void saveArrayToFile(String fileName, int[] array) throws IOException {
Files.write( // write to file
Paths.get(fileName), // get path from file
Collections.singleton(Arrays.toString(array)), // transform array to collection using singleton
Charset.forName("UTF-8") // formatting
);
}
This is what ended up working best for me. I used jQuery fadeTo because this is on WordPress, which already links jQuery in. Otherwise, I probably would have opted for something with pure JavaScript before adding another http request for a plugin.
$(document).ready(function() {
// One "blink" takes 1.5s
setInterval(function(){
// Immediately fade to opacity: 0 in 0ms
$(".cursor").fadeTo( 0, 0);
// Wait .75sec then fade to opacity: 1 in 0ms
setTimeout(function(){
$(".cursor").fadeTo( 0, 1);
}, 750);
}, 1500);
});
Some optimizations:
Code (jsPerf):
var arr = [];
for (var i = 0, ref = arr.length = nl.length; i < ref; i++) {
arr[i] = nl[i];
}
Example: Display different output depending on whether the user is logged in or not.
<?php
if ( is_user_logged_in() ) {
echo 'Welcome, registered user!';
} else {
echo 'Welcome, visitor!';
}
?>
Package & install are various phases in maven build lifecycle. package phase will execute all phases prior to that & it will stop with packaging the project as a jar. Similarly install phase will execute all prior phases & finally install the project locally for other dependent projects.
For understanding maven build lifecycle please go through the following link https://ayolajayamaha.blogspot.in/2014/05/difference-between-mvn-clean-install.html
Two-way binding just means that:
Backbone doesn't have a "baked-in" implementation of #2 (although you can certainly do it using event listeners). Other frameworks like Knockout do wire up two-way binding automagically.
In Backbone, you can easily achieve #1 by binding a view's "render" method to its model's "change" event. To achieve #2, you need to also add a change listener to the input element, and call model.set
in the handler.
Here's a Fiddle with two-way binding set up in Backbone.
solve using this code:
npm install npm@latest -g
VisualSVN for Windows has a command-line-only executable (as well Visual Studio plugins). See https://www.visualsvn.com/downloads/
It is completely portable, so no installation is necessary.
See any reference manual, such as the man page:
f,F
The double argument is rounded and converted to decimal notation in the style [-]ddd.ddd, where the number of digits after the decimal-point character is equal to the precision specification. If the precision is missing, it is taken as 6; if the precision is explicitly zero, no decimal-point character appears. If a decimal point appears, at least one digit appears before it. (The SUSv2 does not know about F and says that character string representations for infinity and NaN may be made available. The C99 standard specifies '[-]inf' or '[-]infinity' for infinity, and a string starting with 'nan' for NaN, in the case of f conversion, and '[-]INF' or '[-]INFINITY' or 'NAN*' in the case of F conversion.)
g,G
The double argument is converted in style f or e (or F or E for G conversions). The precision specifies the number of significant digits. If the precision is missing, 6 digits are given; if the precision is zero, it is treated as 1. Style e is used if the exponent from its conversion is less than -4 or greater than or equal to the precision. Trailing zeros are removed from the fractional part of the result; a decimal point appears only if it is followed by at least one digit.
There should be three pages here:
I don't see this short, linear flow being sufficiently complex to warrant using Spring Web Flow.
I would just use straight Spring Web MVC for steps 1 and 2. I wouldn't use Spring Security for the initial login form, because Spring Security's login form expects a password and a login processing URL. Similarly, Spring Security doesn't provide special support for CAPTCHAs or security questions, so you can just use Spring Web MVC once again.
You can handle step 3 using Spring Security, since now you have a username and a password. The form login page should display the security image, and it should include the user-provided username as a hidden form field to make Spring Security happy when the user submits the login form. The only way to get to step 3 is to have a successful POST
submission on step 1 (and 2 if applicable).
You can use retainAll method and get the intersection of your two sets.
This error can occur if you are installing a package with a different bitness than your Python version. To see whether your Python installation is 32- or 64-bit, see here.
Some superpacks (e.g. for Scipy) available on SourceForge or python.org are for 32-bit systems and some are for 64-bit systems. See this answer. In Windows, uninstalling the 32-bit and installing the 64-bit version (or vice versa if your installation is 32-bit) can solve the problem.
ListaServizi.Sort();
Will do that for you. It's straightforward enough with a list of strings. You need to be a little cleverer if sorting objects.
You need JDK for that.

Addon for Ubuntu (Ubuntu 10.04 LTS (Lucid Lynx)):
The repository moved, but a
pip install -e git+http://github.com/scipy/scipy/#egg=scipy
failed for me... With the following steps, it finally worked out (as root in a virtual environment, where python3
is a link to Python 3.2.2):
install the Ubuntu dependencies (see elaichi), clone NumPy and SciPy:
git clone git://github.com/scipy/scipy.git scipy
git clone git://github.com/numpy/numpy.git numpy
Build NumPy (within the numpy
folder):
python3 setup.py build --fcompiler=gnu95
Install SciPy (within the scipy
folder):
python3 setup.py install
Try c.ToString("F6");
(For a full explanation of numeric formatting, see MSDN)
By setting the schedule period to 15 13 * * *
you tell Jenkins to schedule the build every day of every month of every year at the 15th minute of the 13th hour of the day.
Jenkins used a cron expression, and the different fields are:
If you want to schedule your build every 5 minutes, this will do the job : */5 * * * *
If you want to schedule your build every day at 8h00, this will do the job : 0 8 * * *
For the past few versions (2014), Jenkins have a new parameter, H
(extract from the Jenkins code documentation):
To allow periodically scheduled tasks to produce even load on the system, the symbol
H
(for “hash”) should be used wherever possible.For example, using
0 0 * * *
for a dozen daily jobs will cause a large spike at midnight. In contrast, usingH H * * *
would still execute each job once a day, but not all at the same time, better using limited resources.
Note also that:
The
H
symbol can be thought of as a random value over a range, but it actually is a hash of the job name, not a random function, so that the value remains stable for any given project.
You can use the event ProgressChanged ; the last time it is raised will indicate that the document is fully rendered:
this.webBrowser.ProgressChanged += new
WebBrowserProgressChangedEventHandler(webBrowser_ProgressChanged);
C++20 will have "uniform container erasure", and you'll be able to write:
std::erase_if(numbers, [](int n){ return n % 2 == 0 });
And that will work for vector
, set
, deque
, etc.
See cppReference for more info.
Short answer: One package per module/feature, possibly with sub-packages. Put closely related things together in the same package. Avoid circular dependencies between packages.
Long answer: I agree with most of this article
Is the $_SESSION['name'] variable an array? If you want to delete a specific key from within an array, you have to refer to that exact key in the unset() call, otherwise you delete the entire array, e.g.
$name = array(0 => 'a', 1 => 'b', 2 => 'c');
unset($name); // deletes the entire array
unset($name[1]); // deletes only the 'b' entry
Another minor problem with your snippet: You're mixing GET query parameters in with a POST form. Is there any reason why you can't do the forms with 'name' being passed in a hidden field? It's best to not mix get and post variables, especially if you use $_REQUEST elsewhere. You can run into all kinds of fun trying to figure out why $_GET['name'] isn't showing up the same as $_POST['name'], because the server's got a differnt EGPCS order set in the 'variables_order' .ini setting.
<form blah blah blah method="post">
<input type="hidden" name="name" value="<?= htmlspecialchars($list1) ?>" />
<input type="submit" name="add" value="Add />
</form>
And note the htmlspecialchars() call. If either $list1 or $list2 contain a double quote ("), it'll break your HTML
This looks cool.

In the following example i created a decorator
(runs only once per app at configuration phase) and adds an extra property to $state
service, so this approach does not add global variables to $rootscope
and does not require to add any extra dependency to other services than $state
.
In my example i needed to redirect a user to the index page when he was already signed in and when he was not to redirect him to the previous "protected" page after sign in.
The only unknown services (for you) that i use are authenticationFactory
and appSettings
:
authenticationFactory
just administrates the user login. In this case i use only a method to identify if the user is logged in or not.appSettings
are constants just for not use strings everywhere. appSettings.states.login
and appSettings.states.register
contain the name of the state for the login and register url.Then in any controller
/service
etc you need to inject $state
service and you can access current and previous url like this:
$state.current.name
$state.previous.route.name
From the Chrome console:
var injector = angular.element(document.body).injector();
var $state = injector.get("$state");
$state.current.name;
$state.previous.route.name;
Implementation:
(I'm using angular-ui-router v0.2.17
and angularjs v1.4.9
)
(function(angular) {
"use strict";
function $stateDecorator($delegate, $injector, $rootScope, appSettings) {
function decorated$State() {
var $state = $delegate;
$state.previous = undefined;
$rootScope.$on("$stateChangeSuccess", function (ev, to, toParams, from, fromParams) {
$state.previous = { route: from, routeParams: fromParams }
});
$rootScope.$on("$stateChangeStart", function (event, toState/*, toParams, fromState, fromParams*/) {
var authenticationFactory = $injector.get("authenticationFactory");
if ((toState.name === appSettings.states.login || toState.name === appSettings.states.register) && authenticationFactory.isUserLoggedIn()) {
event.preventDefault();
$state.go(appSettings.states.index);
}
});
return $state;
}
return decorated$State();
}
$stateDecorator.$inject = ["$delegate", "$injector", "$rootScope", "appSettings"];
angular
.module("app.core")
.decorator("$state", $stateDecorator);

aac // no match
abc // no match
acc // no match
a c // match
azc // match
ac // no match
azzc // no match
(Don't confuse the ^
here in [^]
with its other usage as the start of line character: ^
= line start, $
= line end.)
Use the optional character ?
after any character to specify zero or one occurrence of that character. Thus, you would use .?
to match any single character optionally.
Example regex: a.?c
abc // match
a c // match
azc // match
ac // match
abbc // no match
Rows("2:2").Select
ActiveWindow.FreezePanes = True
Select a different range for a different effect, much the same way you would do manually. The "Freeze Top Row" really just is a shortcut new in Excel 2007 (and up), it contains no added functionality compared to earlier versions of Excel.
Uhh, I don't know why everyone suggests serializing the array.
I say, the best way is to actually fit it into your database schema. I have no idea (and you gave no clues) about the actual semantic meaning of the data in your array, but there are generally two ways of storing sequences like that
create table mydata (
id int not null auto_increment primary key,
field1 int not null,
field2 int not null,
...
fieldN int not null
)
This way you are storing your array in a single row.
create table mydata (
id int not null auto_increment primary key,
...
)
create table myotherdata (
id int not null auto_increment primary key,
mydata_id int not null,
sequence int not null,
data int not null
)
The disadvantage of the first method is, obviously, that if you have many items in your array, working with that table will not be the most elegant thing. It is also impractical (possible, but quite inelegant as well - just make the columns nullable) to work with sequences of variable length.
For the second method, you can have sequences of any length, but of only one type. You can, of course, make that one type varchar or something and serialize the items of your array. Not the best thing to do, but certainly better, than serializing the whole array, right?
Either way, any of this methods gets a clear advantage of being able to access an arbitrary element of the sequence and you don't have to worry about serializing arrays and ugly things like that.
As for getting it back. Well, get the appropriate row/sequence of rows with a query and, well, use a loop.. right?
My solution is simplier and checked on Ruby 2.0. It also enable download Json. (run CMD.exe as administrator)
C:\RubyDev>devkitvars.bat
Adding the DevKit to PATH...
And then write again gem command.
Before killing sessions, if possible do
ALTER SYSTEM ENABLE RESTRICTED SESSION;

You can use the map

HTH and if you find a bug let me know
Part One - Polyfill
For browsers that haven't implemented it, a polyfill for array.find
. Courtesy of MDN.
if (!Array.prototype.find) {
Array.prototype.find = function(predicate) {
if (this == null) {
throw new TypeError('Array.prototype.find called on null or undefined');
}
if (typeof predicate !== 'function') {
throw new TypeError('predicate must be a function');
}
var list = Object(this);
var length = list.length >>> 0;
var thisArg = arguments[1];
var value;
for (var i = 0; i < length; i++) {
value = list[i];
if (predicate.call(thisArg, value, i, list)) {
return value;
}
}
return undefined;
};
}
Part Two - Interface
You need to extend the open Array interface to include the find
method.
interface Array<T> {
find(predicate: (search: T) => boolean) : T;
}
When this arrives in TypeScript, you'll get a warning from the compiler that will remind you to delete this.
Part Three - Use it
The variable x
will have the expected type... { id: number }
var x = [{ "id": 1 }, { "id": -2 }, { "id": 3 }].find(myObj => myObj.id < 0);

Here is a definition of a range function that behaves exactly like Python's range
type except that this one is not lazy. It should be easy to turn it into a generator.
The arguments to the range constructor must be numbers. If the step argument is omitted, it defaults to 1. If the start argument is omitted, it defaults to 0. If step is zero, an error is raised.
range = (start, stop, step=1) => {
if(step === 0) throw new Error("range() arg 3 must not be zero");
const noStart = stop == null;
stop = noStart ? start : stop;
start = noStart ? 0 : start;
const length = Math.ceil(((stop - start) / step));
return Array.from({length}, (_, i) => (i * step) + start);
}
console.log(range(-10, 10, 2));
//output [Array] [-10,-8,-6,-4,-2,0,2,4,6,8]
console.log(range(10));
// [Array] [0,1,2,3,4,5,6,7,8,9]
console.log(3, 12);
// [Array] [3,4,5,6,7,8,9,10,11]

You create a form with hidden inputs that hold the values to be posted, set the action of the form to the destination url, and the form method to post. Then, when your link is clicked, trigger a JS function that submits the form.
See here, for an example. This example uses pure JavaScript, with no jQuery — you could choose this if you don't want to install anything more than you already have.
<form name="myform" action="handle-data.php" method="post">
<label for="query">Search:</label>
<input type="text" name="query" id="query"/>
<button>Search</button>
</form>
<script>
var button = document.querySelector('form[name="myform"] > button');
button.addEventListener(function() {
document.querySelector("form[name="myform"]").submit();
});
</script>

I would create a user control which holds a Label and a Text Box in it and simply create instances of that user control 'n' times. If you want to know a better way to do it and use properties to get access to the values of Label and Text Box from the user control, please let me know.
Simple way to do it would be:
int n = 4; // Or whatever value - n has to be global so that the event handler can access it
private void btnDisplay_Click(object sender, EventArgs e)
{
TextBox[] textBoxes = new TextBox[n];
Label[] labels = new Label[n];
for (int i = 0; i < n; i++)
{
textBoxes[i] = new TextBox();
// Here you can modify the value of the textbox which is at textBoxes[i]
labels[i] = new Label();
// Here you can modify the value of the label which is at labels[i]
}
// This adds the controls to the form (you will need to specify thier co-ordinates etc. first)
for (int i = 0; i < n; i++)
{
this.Controls.Add(textBoxes[i]);
this.Controls.Add(labels[i]);
}
}
The code above assumes that you have a button btnDisplay
and it has a onClick
event assigned to btnDisplay_Click
event handler. You also need to know the value of n and need a way of figuring out where to place all controls. Controls should have a width and height specified as well.
To do it using a User Control simply do this.
Okay, first of all go and create a new user control and put a text box and label in it.
Lets say they are called txtSomeTextBox
and lblSomeLabel
. In the code behind add this code:
public string GetTextBoxValue()
{
return this.txtSomeTextBox.Text;
}
public string GetLabelValue()
{
return this.lblSomeLabel.Text;
}
public void SetTextBoxValue(string newText)
{
this.txtSomeTextBox.Text = newText;
}
public void SetLabelValue(string newText)
{
this.lblSomeLabel.Text = newText;
}
Now the code to generate the user control will look like this (MyUserControl is the name you have give to your user control):
private void btnDisplay_Click(object sender, EventArgs e)
{
MyUserControl[] controls = new MyUserControl[n];
for (int i = 0; i < n; i++)
{
controls[i] = new MyUserControl();
controls[i].setTextBoxValue("some value to display in text");
controls[i].setLabelValue("some value to display in label");
// Now if you write controls[i].getTextBoxValue() it will return "some value to display in text" and controls[i].getLabelValue() will return "some value to display in label". These value will also be displayed in the user control.
}
// This adds the controls to the form (you will need to specify thier co-ordinates etc. first)
for (int i = 0; i < n; i++)
{
this.Controls.Add(controls[i]);
}
}
Of course you can create more methods in the usercontrol to access properties and set them. Or simply if you have to access a lot, just put in these two variables and you can access the textbox and label directly:
public TextBox myTextBox;
public Label myLabel;
In the constructor of the user control do this:
myTextBox = this.txtSomeTextBox;
myLabel = this.lblSomeLabel;
Then in your program if you want to modify the text value of either just do this.
control[i].myTextBox.Text = "some random text"; // Same applies to myLabel
Hope it helped :)
Are you keeping references to variables that you no longer need (e.g. data from the previous simulations)? If so, you have a memory leak. You just need to find where that is happening and make sure that you remove the references to the variables when they are no longer needed (this would automatically happen if they go out of scope).
If you actually need all that data from previous simulations in memory, you need to increase the heap size or change your algorithm.
Very first will declare outer Arraylist which will contain another inner Arraylist inside it
ArrayList> CompletesystemStatusArrayList; ArrayList systemStatusArrayList
CompletesystemStatusArrayList=new ArrayList
systemStatusArrayList=new ArrayList();
systemStatusArrayList.add("1");
systemStatusArrayList.add("2");
systemStatusArrayList.add("3");
systemStatusArrayList.add("4");
systemStatusArrayList.add("5");
systemStatusArrayList.add("6");
systemStatusArrayList.add("7");
systemStatusArrayList.add("8");
CompletesystemStatusArrayList.add(systemStatusArrayList);
One way to do this without JS is to use the hover action to reveal a HTML element that is otherwise hidden, see this codepen:
http://codepen.io/c0un7z3r0/pen/LZWXEw
Note that the span that contains the tooltip content is relative to the parent li. The magic is here:
ul#list_of_thrones li > span{
display:none;
}
ul#list_of_thrones li:hover > span{
position: absolute;
display:block;
...
}
As you can see, the span is hidden unless the listitem is hovered over, thus revealing the span element, the span can contain as much html as you need. In the codepen attached I have also used a :after element for the arrow but that of course is entirely optional and has only been included in this example for cosmetic purposes.
I hope this helps, I felt compelled to post as all the other answers included JS solutions but the OP asked for a HTML/CSS only solution.
I had to copy the non-input boxes text (text within any div/span tag) from the page and came up with following code. The only trick is to have a hidden field, but as type TEXT. It won't work with type hidden.
function copyToClipboard(sID) {
var aField = document.getElementById("hiddenField");
aField.hidden = false;
aField.value = document.getElementById(sID).textContent;
aField.select();
document.execCommand("copy");
alert("Following text has been copied to the clipboard.\n\n" + aField.value);
aField.hidden = true;
}
And in the HTML add the following:
input type="text" id="hiddenField" style="width:5px;border:0" />
...
Instead of adding the line breaks with nl2br() and then removing the line breaks with explode(), try using the line break character '\r' or '\n' or '\r\n'.
<?php $options= file_get_contents("employees.txt"); $options=explode("\n",$options); // try \r as well. foreach ($options as $singleOption){ echo "<option value='".$singleOption."'>".$singleOption."</option>"; } ?>
This could also fix the issue if the problem was due to Google Spreadsheets reading the line breaks.
protected void gvTurnos_RowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.EmptyDataRow)
{
LinkButton btn = (LinkButton)e.Row.FindControl("btnAgregarVacio");
if (btn != null)
{
btn.Visible = rbFiltroEstatusCampus.SelectedValue == "1" ? true : false;
}
}
}
catch (Exception ex)
{
throw ex;
}
}
As Joshua Bloch notes in Effective Java:
You can use an Enum if all your constants are related (like planet names), put the constant values in classes they are related to (if you have access to them), or use a non instanciable utility class (define a private default constructor).
class SomeConstants
{
// Prevents instanciation of myself and my subclasses
private SomeConstants() {}
public final static String TOTO = "toto";
public final static Integer TEN = 10;
//...
}
Then, as already stated, you can use static imports to use your constants.
If you look at the exception stack trace it says that, it failed to convert from ABDeadlineType
to DeadlineType
. Because your repository is going to return you the objects of ABDeadlineType
. How the spring-data-jpa
will convert into the other one(DeadlineType
). You should return the same type from repository and then have some intermediate util class to convert it into your model class.
public interface ABDeadlineTypeRepository extends JpaRepository<ABDeadlineType, Long> {

We experienced these errors intermittently after upgraded from 11g to 12c and our java was on 1.6.
The fix for us was to upgrade java and jdbc from 6 to 7
export JAVA_HOME='/usr/java1.7'
export CLASSPATH=/u01/app/oracle/product/12.1.0/dbhome_1/jdbc/libojdbc7.jar:$CLASSPATH
Several days later, still intermittent connection resets.
We ended up removing all the java 7 above. Java 6 was fine. The problem was fixed by adding this to our user bash_profile.
Our groovy scripts that were experiencing the error were using /dev/random on our batch VM server. Below forced java and groovy to use /dev/urandom.
export JAVA_OPTS=" $JAVA_OPTS -Djava.security.egd=file:///dev/urandom "
TCC and TCC/LE from JPSoft are CMD.EXE replacements that add significant functionality. Relevant to the OP's question, which
is a builtin command for TCC family command processors.
Another way is to make your user a password-less sudo user
.
Type the following on command line:
sudo visudo
Then add the following and replace the <username>
with yours:
<username> ALL=(ALL) NOPASSWD: ALL
This will allow the user to execute sudo
command without having to ask for password (including application launched by the said user. This might be a security risk though
I had same problem, my issue was that downloaded Apache 2.4 but 32 bits. Then re-download 64bits version and it's works.

If you want to bind a string to the src
attribute, you should wrap it on single quotes:
<img v-bind:src="'/static/img/clear.gif'">
<!-- or shorthand -->
<img :src="'/static/img/clear.gif'">
IMO you do not need to bind a string, you could use the simple way:
<img src="/static/img/clear.gif">

1.Purposes of using a fragment?
You got half of the answer! Now that you created the event handler, you need to hook it to the form so that it actually gets called when the form is loading. You can achieve that by doing the following:
public class ProgramViwer : Form{
public ProgramViwer()
{
InitializeComponent();
Load += new EventHandler(ProgramViwer_Load);
}
private void ProgramViwer_Load(object sender, System.EventArgs e)
{
formPanel.Controls.Clear();
formPanel.Controls.Add(wel);
}
}
I didn't find it listed so updating the list.
You need to have the apk installed and running in front on your phone for this solution:

OUTPUT for Calculator package would be:

mFocusedApp=AppWindowToken{29a4bed4 token=Token{2f850b1a ActivityRecord{eefe5c5 u0 com.android.calculator2/.Calculator t322}}}
Main part is, First Line:
Window #7 Window{39ced4b1 u0 com.android.calculator2/com.android.calculator2.Calculator}:
First part of the output is package name:
com.android.calculator2
Second Part of output (which is after /
) can be two things, in our case its:
com.android.calculator2.Calculator
<PKg name>.<activity name>
=
<com.android.calculator2>.<Calculator>
so .Calculator
is our activity
If second part is entirely different from Package name and doesn't seem to contain pkg name which was before /
in out output, then entire
second part can be used as main activity.

If you think of the std::list
like a queue, then you can dequeue and enqueue all the items that you want to keep, but only dequeue (and not enqueue) the item you want to remove. Here's an example where I want to remove 5 from a list containing the numbers 1-10...
std::list<int> myList;
int size = myList.size(); // The size needs to be saved to iterate through the whole thing
for (int i = 0; i < size; ++i)
{
int val = myList.back()
myList.pop_back() // dequeue
if (val != 5)
{
myList.push_front(val) // enqueue if not 5
}
}
myList
will now only have numbers 1-4 and 6-10.
A bit late to the party but, should you have root access, you can do the following directly:
Log into your mysql as root,
$ mysql -u root -p
Show databases;
mysql>SHOW DATABASES;
Select mysql database, which is where all privileges info is located
mysql>USE mysql;
Show tables.
mysql>SHOW TABLES;
The table concerning privileges for your case is 'db', so let's see what columns it has:
mysql>DESC db;
In order to list the users privileges, type the following command, for example:
mysql>SELECT user, host, db, Select_priv, Insert_priv, Update_priv, Delete_priv FROM db ORDER BY user, db;
If you can't find that user or if you see that that user has a 'N' in the Select_priv column, then you have to either INSERT or UPDATE accordingly:
INSERT:
INSERT INTO db (Host,Db,User,Select_priv,Insert_priv,Update_priv,Delete_priv) VALUES ('localhost','DBname','UserName','Y' ,'N','N','N');
UPDATE:
UPDATE db SET Select_priv = 'Y' WHERE User = 'UserName' AND Db = 'DBname' AND Host='localhost';
Finally, type the following command:
mysql>FLUSH PRIVILEGES;
Ciao.
The solution is to do exactly what the exception message tells you:
Caused by: org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations)
Remove the deleted object from an associations (sets, lists, or maps) that it is in. In particular, i suspect, from PlayList.PlaylistadMaps
. It's not enough to just delete the object, you have to remove it from any cascading collections which refer to it.
In fact, since your collection has orphanRemoval = true
, you don't need to delete it explicitly. You just need to remove it from the set.
I think this answer needs an update, check the edit history for the old answer.
Basically, you have three deferent cases null, undefined, and undeclared, see the snippet below.
// bad-file.ts
console.log(message)
You'll get an error says that variable message
is undefined (aka undeclared), of course, the Typescript compiler shouldn't let you do that but REALLY nothing can prevent you.
// evil-file.ts
// @ts-gnore
console.log(message)
The compiler will be happy to just compile the code above. So, if you're sure that all variables are declared you can simply do that
if ( message != null ) {
// do something with the message
}
the code above will check for null
and undefined
, BUT in case the message
variable may be undeclared (for safety), you may consider the following code
if ( typeof(message) !== 'undefined' && message !== null ) {
// message variable is more than safe to be used.
}
Note: the order here typeof(message) !== 'undefined' && message !== null
is very important you have to check for the undefined
state first atherwise it will be just the same as message != null
, thanks @Jaider.
I had this same issue where I wanted to initialize my MySQL Docker instance's schema, but I ran into difficulty getting this working after doing some Googling and following others' examples. Here's how I solved it.
1) Dump your MySQL schema to a file.
mysqldump -h <your_mysql_host> -u <user_name> -p --no-data <schema_name> > schema.sql
2) Use the ADD command to add your schema file to the /docker-entrypoint-initdb.d
directory in the Docker container. The docker-entrypoint.sh
file will run any files in this directory ending with ".sql"
against the MySQL database.
Dockerfile:
FROM mysql:5.7.15
MAINTAINER me
ENV MYSQL_DATABASE=<schema_name> \
MYSQL_ROOT_PASSWORD=<password>
ADD schema.sql /docker-entrypoint-initdb.d
EXPOSE 3306
3) Start up the Docker MySQL instance.
docker-compose build
docker-compose up
Thanks to Setting up MySQL and importing dump within Dockerfile for clueing me in on the docker-entrypoint.sh and the fact that it runs both SQL and shell scripts!
If table_2
is empty, then try the following insert statement:
insert into table_2 (itemid,location1)
select itemid,quantity from table_1 where locationid=1
If table_2
already contains the itemid
values, then try this update statement:
update table_2 set location1=
(select quantity from table_1 where locationid=1 and table_1.itemid = table_2.itemid)
sentence.sub! 'Robert', 'Joe'
Won't cause an exception if the replaced word isn't in the sentence (the []=
variant will).
The above replaces only the first instance of "Robert".
To replace all instances use gsub
/gsub!
(ie. "global substitution"):
sentence.gsub! 'Robert', 'Joe'
The above will replace all instances of Robert with Joe.
I was trying to set the log_statement
in some postgres config file but in fact the file was not read by our postgres.
I confirmed that using the request :
select *
from pg_settings
[...]
log_statement none # That was not the value i was expected for !!!
I use this way https://stackoverflow.com/a/41912295/2294168
command: postgres -c config_file=/etc/postgresql.conf
Another workaround would be to make use of prettier to format the JSON. The example below is using 'json' parser but it could also use 'json5', see list of valid parsers.
const prettier = require("prettier");
console.log(prettier.format(JSON.stringify(object),{ semi: false, parser: "json" }));
You can achieve this with the following code:
$("input").change(function(e) {
for (var i = 0; i < e.originalEvent.srcElement.files.length; i++) {
var file = e.originalEvent.srcElement.files[i];
var img = document.createElement("img");
var reader = new FileReader();
reader.onloadend = function() {
img.src = reader.result;
}
reader.readAsDataURL(file);
$("input").after(img);
}
});
When I encountered this exception, I solved this by using Run Configurations... panel as picture shows below.Especially, at JRE tab, the VM Arguments are the critical
( "-Xmx1024m -Xms512m -XX:MaxPermSize=1024m -XX:PermSize=512m" ).
In most cases (including this one), return
will exit immediately. However, if the return is in a try
block with an accompanying finally
block, the finally
always executes and can "override" the return
in the try
.
function foo() {
try {
for (var i = 0; i < 10; i++) {
if (i % 3 == 0) {
return i; // This executes once
}
}
} finally {
return 42; // But this still executes
}
}
console.log(foo()); // Prints 42
You can use WScript.Arguments
to access the arguments passed to your script.
Calling the script:
cscript.exe test.vbs "C:\temp\"
Inside your script:
Set File = FSO.OpenTextFile(WScript.Arguments(0) &"\test.txt", 2, True)
Don't forget to check if there actually has been an argument passed to your script. You can do so by checking the Count
property:
if WScript.Arguments.Count = 0 then
WScript.Echo "Missing parameters"
end if
If your script is over after you close the file then there is no need to set the variables to Nothing
. The resources will be cleaned up automatically when the cscript.exe process terminates. Setting a variable to Nothing
usually is only necessary if you explicitly want to free resources during the execution of your script. In that case, you would set variables which contain a reference to a COM object to Nothing
, which would release the COM object before your script terminates. This is just a short answer to your bonus question, you will find more information in these related questions:
Is there a need to set Objects to Nothing inside VBA Functions
I had this error with following statement
Experimental support for decorators is a feature that is subject to change in a future release. Set the 'experimentalDecorators' option in your tsconfig or jsconfig to remove this warning.ts(1219)
It was there because my Component was not registered in AppModule or (app.module.ts) i simply gave the namespace like
import { abcComponent } from '../app/abc/abc.component';
and also registered it in declarations
JSON in any HTML tag except <script>
tag would be a mere text. Thus it's like you add a story to your HTML page.
However, about formatting, that's another matter. I guess you should change the title of your question.
The problem I had was that I was putting the --env-file at the end of the command
docker run -it --rm -p 8080:80 imagename --env-file ./env.list
Fix
docker run --env-file ./env.list -it --rm -p 8080:80 imagename
try like this
= IIF( MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ) ) = -1, "", FormatNumber( MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ), "CellReading_Reading"),3)) )

The modern approach uses the java.time classes.
YearMonth.from(
ZonedDateTime.parse(
"Mon Mar 14 16:02:37 GMT 2011" ,
DateTimeFormatter.ofPattern( "E MMM d HH:mm:ss z uuuu" )
)
).toString()
2011-03
The modern way is with java.time classes. The old date-time classes such as Calendar
have proven to be poorly-designed, confusing, and troublesome.
Define a custom formatter to match your string input.
String input = "Mon Mar 14 16:02:37 GMT 2011";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "E MMM d HH:mm:ss z uuuu" );
Parse as a ZonedDateTime
.
ZonedDateTime zdt = ZonedDateTime.parse( input , f );
You are interested in the year and month. The java.time classes include YearMonth
class for that purpose.
YearMonth ym = YearMonth.from( zdt );
You can interrogate for the year and month numbers if needed.
int year = ym.getYear();
int month = ym.getMonthValue();
But the toString
method generates a string in standard ISO 8601 format.
String output = ym.toString();
Put this all together.
String input = "Mon Mar 14 16:02:37 GMT 2011";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "E MMM d HH:mm:ss z uuuu" );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );
YearMonth ym = YearMonth.from( zdt );
int year = ym.getYear();
int month = ym.getMonthValue();
Dump to console.
System.out.println( "input: " + input );
System.out.println( "zdt: " + zdt );
System.out.println( "ym: " + ym );
input: Mon Mar 14 16:02:37 GMT 2011
zdt: 2011-03-14T16:02:37Z[GMT]
ym: 2011-03
See this code running in IdeOne.com.
If you must have a Calendar
object, you can convert to a GregorianCalendar
using new methods added to the old classes.
GregorianCalendar gc = GregorianCalendar.from( zdt );
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to java.time.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
IDE: The MS Office of Programming. It's where you type your code, plus some added features to make you a happier programmer. (e.g. Eclipse, Netbeans). Car body: It's what you really touch, see and work on.
Library: A library is a collection of functions, often grouped into multiple program files, but packaged into a single archive file. This contains programs created by other folks, so that you don't have to reinvent the wheel. (e.g. junit.jar, log4j.jar). A library generally has a key role, but does all of its work behind the scenes, it doesn't have a GUI. Car's engine.
API: The library publisher's documentation. This is how you should use my library. (e.g. log4j API, junit API). Car's user manual - yes, cars do come with one too!
What is a kit? It's a collection of many related items that work together to provide a specific service. When someone says medicine kit, you get everything you need for an emergency: plasters, aspirin, gauze and antiseptic, etc.
SDK: McDonald's Happy Meal. You have everything you need (and don't need) boxed neatly: main course, drink, dessert and a bonus toy. An SDK is a bunch of different software components assembled into a package, such that they're "ready-for-action" right out of the box. It often includes multiple libraries and can, but may not necessarily include plugins, API documentation, even an IDE itself. (e.g. iOS Development Kit).
Toolkit: GUI. GUI. GUI. When you hear 'toolkit' in a programming context, it will often refer to a set of libraries intended for GUI development. Since toolkits are UI-centric, they often come with plugins (or standalone IDE's) that provide screen-painting utilities. (e.g. GWT)
Framework: While not the prevalent notion, a framework can be viewed as a kit. It also has a library (or a collection of libraries that work together) that provides a specific coding structure & pattern (thus the word, framework). (e.g. Spring Framework)
just use class='text-center' in element for center heading.
<h2 class="text-center">sample center heading</h2>
use class='text-left' in element for left heading, and use class='text-right' in element for right heading.
This will do the job just fine , and even handle subdirs being specified:
$(CC) $(CFLAGS) -MD -o $@ $<
tested it with gcc 4.8.3
You can also write:
[e] * n
You should note that if e is for example an empty list you get a list with n references to the same list, not n independent empty lists.
Performance testing
At first glance it seems that repeat is the fastest way to create a list with n identical elements:
>>> timeit.timeit('itertools.repeat(0, 10)', 'import itertools', number = 1000000)
0.37095273281943264
>>> timeit.timeit('[0] * 10', 'import itertools', number = 1000000)
0.5577236771712819
But wait - it's not a fair test...
>>> itertools.repeat(0, 10)
repeat(0, 10) # Not a list!!!
The function itertools.repeat
doesn't actually create the list, it just creates an object that can be used to create a list if you wish! Let's try that again, but converting to a list:
>>> timeit.timeit('list(itertools.repeat(0, 10))', 'import itertools', number = 1000000)
1.7508119747063233
So if you want a list, use [e] * n
. If you want to generate the elements lazily, use repeat
.
There are two ways:
Just use tomcat manager console for console deployment or simply copy and paste your application in webapp folder of your server's tomcat_home directory.
Note: Make sure if your war file size is more than 52 MB (the default configuration value), you need to make two little changes in web.xml file of Manager application of your webapp folder(Manager application is provided by Apache tomcat by default upon installing the server).
Go to the web.xml of the manager application (for instance it could be under /tomcat7/webapps/manager/WEB-INF/web.xml.
Increase the max-file-size and max-request-size values in web.xml file:
<multipart-config>
<!– 50MB max –>
<max-file-size>52428800</max-file-size>
<max-request-size>52428800</max-request-size>
<file-size-threshold>0</file-size-threshold>
</multipart-config>
Increase the size by putting the values for <max-file-size>
and <max-request-size>
according to your requirement.
This will definitely work, In this, Send message without using any intent .
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("Phone Number", null, "Message", null, null);
This code is used for send message in background (Not showing message composer), It can also work inside the Broadcast receiver. If you want to send a message from Broadcast receiver.

Here is an example from my code (for threaded pool, but just change class name and you'll have process pool):
def execute_run(rp):
... do something
pool = ThreadPoolExecutor(6)
for mat in TESTED_MATERIAL:
for en in TESTED_ENERGIES:
for ecut in TESTED_E_CUT:
rp = RunParams(
simulations, DEST_DIR,
PARTICLE, mat, 960, 0.125, ecut, en
)
pool.submit(execute_run, rp)
pool.join()
Basically:
pool = ThreadPoolExecutor(6)
creates a pool for 6 threadspool.submit(execute_run, rp)
adds a task to pool, first arogument is a function called in in a thread/process, rest of the arguments are passed to the called function. pool.join
waits until all tasks are done. This problem is related to missing the Visual Studio "redistributable package." It is not obvious which one is missing based on the dependency walk, but I would try the one that corresponds with your compiler version first and see if things run properly:
I ran into this problem because I am using the Visual Studio compilers, but not the full Visual Studio environment.
Going to dare to inject a new link here: The latest supported Visual C++ downloads. Stein Åsmul, 29.11.2018.
to solve this problem go to Build phases and search about duplicate file like (facebookSDK , unityads ) and delete (extension file.o) then build again .
Use $(this).find()
, or pass this in context, using jQuery context with selector.
Using $(this).find()
$(".class").click(function(){
$(this).find(".subclass").css("visibility","visible");
});
Using this
in context, $( selector, context )
, it will internally call find function, so better to use find on first place.
$(".class").click(function(){
$(".subclass", this).css("visibility","visible");
});
Modules Preconditions:
The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (
precondition="managedHandler"
) only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />
If you remove the attribute
precondition="managedHandler"
, Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "
managedHandler
" precondition.To enable all managed modules to run for all requests without configuring each module entry to remove the "
managedHandler
" precondition, use therunAllManagedModulesForAllRequests
property in the<modules>
section:<modules runAllManagedModulesForAllRequests="true" />
When you use this property, the "
managedHandler
" precondition has no effect and all managed modules run for all requests.

An alternative approach with vue-cli
version 3 is to add a .env
file in the root project directory (along side package.json
) with the contents:
PORT=3000
Running npm run serve
will now indicate the app is running on port 3000.
The terminology "dynamically typed" is unfortunately misleading. All languages are statically typed, and types are properties of expressions (not of values as some think). However, some languages have only one type. These are called uni-typed languages. One example of such a language is the untyped lambda calculus.
In the untyped lambda calculus, all terms are lambda terms, and the only operation that can be performed on a term is applying it to another term. Hence all operations always result in either infinite recursion or a lambda term, but never signal an error.
However, were we to augment the untyped lambda calculus with primitive numbers and arithmetic operations, then we could perform nonsensical operations, such adding two lambda terms together: (?x.x) + (?y.y)
. One could argue that the only sane thing to do is to signal an error when this happens, but to be able to do this, each value has to be tagged with an indicator that indicates whether the term is a lambda term or a number. The addition operator will then check that indeed both arguments are tagged as numbers, and if they aren't, signal an error. Note that these tags are not types, because types are properties of programs, not of values produced by those programs.
A uni-typed language that does this is called dynamically typed.
Languages such as JavaScript, Python, and Ruby are all uni-typed. Again, the typeof
operator in JavaScript and the type
function in Python have misleading names; they return the tags associated with the operands, not their types. Similarly, dynamic_cast
in C++ and instanceof
in Java do not do type checks.
Are you creating a very large table (hundreds of rows and columns)? If so, table-layout: fixed;
is a good idea, as the browser only needs to read the first row in order to compute and render the entire table
, so it loads faster.
But if not, I would suggest dumping table-layout: fixed;
and changing your css as follows:
table th, table td{
border: 1px solid #000;
width:20px; //or something similar
}
table td.wideRow, table th.wideRow{
width: 300px;
}
In C, use the strstr()
standard library function:
const char *str = "/user/desktop/abc/post/";
const int exists = strstr(str, "/abc/") != NULL;
Take care to not accidentally find a too-short substring (this is what the starting and ending slashes are for).

I just wanted to use the import

Everyone says it's not possible. But, as of May 2018, it's possible to use above in plain Node.js, without any modules like Babel, etc.
Here is a simple way to do it.
Create the below files, run, and see the output for yourself.
Also don't forget to see Explanation
below.
function myFunc() {
console.log("Hello from myFunc")
}
export default myFunc;
import myFunc from "./myfile.mjs" // Simply using "./myfile" may not work in all resolvers

node --version
, it gives me "v10.3.0", though the LTE/stable/recommended version is 8.11.2 LTS.My approach was to make a slight command line variant that adds the registry switch.
I created these files in the nodejs folder where the npm executable is found:
npm-.cmd
:
@ECHO OFF
npm --registry https://registry.npmjs.org %*
npm-
:
#!/bin/sh
"npm" --registry https://registry.npmjs.org "$@"
Now, if I want to do an operation against the normal npm registry (while I am not connected to the VPN), I just type npm-
where I would usually type npm
.
To test this command and see the registry for a package, use this example:
npm- view lodash

You can use Angular $window
:
$window.location.href = '/index.html';
Example usage in a contoller:
(function () {
'use strict';
angular
.module('app')
.controller('LoginCtrl', LoginCtrl);
LoginCtrl.$inject = ['$window', 'loginSrv', 'notify'];
function LoginCtrl($window, loginSrv, notify) {
/* jshint validthis:true */
var vm = this;
vm.validateUser = function () {
loginSrv.validateLogin(vm.username, vm.password).then(function (data) {
if (data.isValidUser) {
$window.location.href = '/index.html';
}
else
alert('Login incorrect');
});
}
}

If you want to manually install NLTK Corpus.
1) Go to http://www.nltk.org/nltk_data/ and download your desired NLTK Corpus file.
2) Now in a Python shell check the value of nltk.data.path
3) Choose one of the path that exists on your machine, and unzip the data files into the corpora sub directory inside.
4) Now you can import the data from nltk.corpos import stopwords

Update: I think you can just switch the order of the array, like so:
jQuery.fn.dataTableExt.oSort['us_date-asc'] = function(a,b) {
var usDatea = a.split('/');
var usDateb = b.split('/');
var x = (usDatea[2] + usDatea[0] + usDatea[1]) * 1;
var y = (usDateb[2] + usDateb[0] + usDateb[1]) * 1;
return ((x < y) ? -1 : ((x > y) ? 1 : 0));
};
jQuery.fn.dataTableExt.oSort['us_date-desc'] = function(a,b) {
var usDatea = a.split('/');
var usDateb = b.split('/');
var x = (usDatea[2] + usDatea[0] + usDatea[1]) * 1;
var y = (usDateb[2] + usDateb[0] + usDateb[1]) * 1;
return ((x < y) ? 1 : ((x > y) ? -1 : 0));
};
All I did was switch the __date_[1]
(day) and __date_[0]
(month), and replaced uk
with us
so you won't get confused. I think that should take care of it for you.
Update #2: You should be able to just use the date object for comparison. Try this:
jQuery.fn.dataTableExt.oSort['us_date-asc'] = function(a,b) {
var x = new Date(a),
y = new Date(b);
return ((x < y) ? -1 : ((x > y) ? 1 : 0));
};
jQuery.fn.dataTableExt.oSort['us_date-desc'] = function(a,b) {
var x = new Date(a),
y = new Date(b);
return ((x < y) ? 1 : ((x > y) ? -1 : 0));
};
If $arrayofStringsNotInterestedIn is an [array] you should use -notcontains:

if ($arrayofStringsNotInterestedIn -notcontains $_) { $) }
or better (IMO)
Get-Content $FileName | where { $arrayofStringsNotInterestedIn -notcontains $_}

As mentioned already, the contents are stored at the server. However the session is identified by a session-id, which is stored at the client and send with each request. Usually the session-id is stored in a cookie, but it can also be appended to urls. (That's the PHPSESSID

Of course, change the GMAIL_USERNAME and GMAIL_PASSWORD values to your particular user and password.
Are you using the HTML5 required attribute?
That will cause Chrome 10 to display a balloon prompting the user to fill out the field.
Javascript can be used, as long as you grab whatever page you're after via a proxy on your domain:
<html>
<head>
<script src="/js/jquery-1.3.2.js"></script>
</head>
<body>
<script>
$.get("www.mydomain.com/?url=www.google.com", function(response) {
alert(response)
});
</script>
</body>
Adding a reference to System.Net.Http.Formatting.dll may cause DLL mismatch issues. Right now, System.Net.Http.Formatting.dll appears to reference version 4.5.0.0 of Newtonsoft.Json.DLL, whereas the latest version is 6.0.0.0. That means you'll need to also add a binding redirect to avoid a .NET Assembly exception if you reference the latest Newtonsoft NuGet package or DLL:
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
</dependentAssembly>
So an alternative solution to adding a reference to System.Net.Http.Formatting.dll is to read the response as a string and then desearalize yourself with JsonConvert.DeserializeObject(responseAsString). The full method would be:
public async Task<T> GetHttpResponseContentAsType(string baseUrl, string subUrl)
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri(baseUrl);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await client.GetAsync(subUrl);
response.EnsureSuccessStatusCode();
var responseAsString = await response.Content.ReadAsStringAsync();
var responseAsConcreteType = JsonConvert.DeserializeObject<T>(responseAsString);
return responseAsConcreteType;
}
}
If you need to insert node/element in some specific place , you can to do next steps
It is simple algorithm but should works...
d = {1:2,3:4}
suppose that we want to change the keys to the list elements p=['a' , 'b']. the following code will do:
d=dict(zip(p,list(d.values())))
and we get
{'a': 2, 'b': 4}
You can throw your own custom errors by extending the Exception class.
class CustomException : Exception {
[string] $additionalData
CustomException($Message, $additionalData) : base($Message) {
$this.additionalData = $additionalData
}
}
try {
throw [CustomException]::new('Error message', 'Extra data')
} catch [CustomException] {
# NOTE: To access your custom exception you must use $_.Exception
Write-Output $_.Exception.additionalData
# This will produce the error message: Didn't catch it the second time
throw [CustomException]::new("Didn't catch it the second time", 'Extra data')
}
For client side files, you cannot get a list of files in a user's local directory.
If the user has provided uploaded files, you can access them via their input
element.
<input type="file" name="client-file" id="get-files" multiple />
<script>
var inp = document.getElementById("get-files");
// Access and handle the files
for (i = 0; i < inp.files.length; i++) {
let file = inp.files[i];
// do things with file
}
</script>
it will work fine for me
Change Following.
Step 1: Make sure ApplicationId And PackageName will Same. example :
android {
defaultConfig {
applicationId "com.example.myapplication"
}
}
and package name the same. package="com.example.myapplication"
Step 2 delete iml file in my case :
Go To Project> >C:\Users\ashif\Documents\MyApplication .iml file // delete
if you forget Project Path Then Go To android Studio Right Click on app and go to Show in Explorer you get your Project and remove .iml file
Step 3 Close Project
Step 4 Now Copy Your old Project and Paste Any other Root or copy Project Folder and paste Any other Dir.
Example C:\Users\ashif\Documents/MyApplication
Step 5
Now open Android Studio and open Existing Project
C:\Users\ashif\Documents/MyApplication
Try it will work
You're overcomplicating things:
var e = $('<div style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
e.attr('id', 'myid');
$('#box').append(e);
For example: http://jsfiddle.net/ambiguous/Dm5J2/
use .NET3.5 it worked for me for similar issue.
This function:
CREATE FUNCTION ToProperCase(@string VARCHAR(255)) RETURNS VARCHAR(255)
AS
BEGIN
DECLARE @i INT -- index
DECLARE @l INT -- input length
DECLARE @c NCHAR(1) -- current char
DECLARE @f INT -- first letter flag (1/0)
DECLARE @o VARCHAR(255) -- output string
DECLARE @w VARCHAR(10) -- characters considered as white space
SET @w = '[' + CHAR(13) + CHAR(10) + CHAR(9) + CHAR(160) + ' ' + ']'
SET @i = 1
SET @l = LEN(@string)
SET @f = 1
SET @o = ''
WHILE @i <= @l
BEGIN
SET @c = SUBSTRING(@string, @i, 1)
IF @f = 1
BEGIN
SET @o = @o + @c
SET @f = 0
END
ELSE
BEGIN
SET @o = @o + LOWER(@c)
END
IF @c LIKE @w SET @f = 1
SET @i = @i + 1
END
RETURN @o
END
Result:
dbo.ToProperCase('ALL UPPER CASE and SOME lower ÄÄ ÖÖ ÜÜ ÉÉ ØØ CC ÆÆ')
-----------------------------------------------------------------
All Upper Case and Some lower Ää Öö Üü Éé Øø Cc Ææ
