This question asked long before. But I thought following information will useful for newbies. Actually you can easily get the values from class name like this.
Sub ExtractLastValue()
Set objIE = CreateObject("InternetExplorer.Application")
objIE.Top = 0
objIE.Left = 0
objIE.Width = 800
objIE.Height = 600
objIE.Visible = True
objIE.Navigate ("https://uk.investing.com/rates-bonds/financial-futures/")
Do
DoEvents
Loop Until objIE.readystate = 4
MsgBox objIE.document.getElementsByClassName("pid-8907-last")(0).innerText
End Sub
And if you are new to web scraping please read this blog post.
And also there are various techniques to extract data from web pages. This article explain few of them with examples.
Similar to the above solutions I used @Input()
in a directive and able to pass multiple arrays of values in the directive.
selector: '[selectorHere]',
@Input() options: any = {};
Input.html
<input selectorHere [options]="selectorArray" />
Array from TS file
selectorArray= {
align: 'left',
prefix: '$',
thousands: ',',
decimal: '.',
precision: 2
};
I'm implementing it in Play Framework and for me it worked like this:
1) Notice that I used data-rule-equalTo in input tag for the id inputPassword1. The code section of userform in my Modal:
<div class="form-group">
<label for="pass1">@Messages("authentication.password")</label>
<input class="form-control required" id="inputPassword1" placeholder="@Messages("authentication.password")" type="password" name="password" maxlength=10 minlength=5>
</div>
<div class="form-group">
<label for="pass2">@Messages("authentication.password2")</label>
<input class="form-control required" data-rule-equalTo="#inputPassword1" id="inputPassword2" placeholder="@Messages("authentication.password")" type="password" name="password2">
</div>
2)Since I used validator within a Modal
$(document).on("click", ".createUserModal", function () {
$(this).find('#userform').validate({
rules: {
firstName: "required",
lastName: "required",
nationalId: {
required: true,
digits:true
},
email: {
required: true,
email: true
},
optradio: "required",
password :{
required: true,
minlength: 5
},
password2: {
required: true
}
},
highlight: function (element) {
$(element).parent().addClass('error')
},
unhighlight: function (element) {
$(element).parent().removeClass('error')
},
onsubmit: true
});
});
Hope it helps someone :).
filepath.Abs("./")
Abs returns an absolute representation of path. If the path is not absolute it will be joined with the current working directory to turn it into an absolute path.
As stated in the comment, this returns the directory which is currently active.
Collations affect how data is sorted and how strings are compared to each other. That means you should use the collation that most of your users expect.
Example from the documentation for charset unicode:
utf8_general_ci
also is satisfactory for both German and French, except that ‘ß’ is equal to ‘s’, and not to ‘ss’. If this is acceptable for your application, then you should useutf8_general_ci
because it is faster. Otherwise, useutf8_unicode_ci
because it is more accurate.
So - it depends on your expected user base and on how much you need correct sorting. For an English user base, utf8_general_ci
should suffice, for other languages, like Swedish, special collations have been created.
As others have said, you should do both. Here's why:
You want to validate input on the client side first because you can give better feedback to the average user. For example, if they enter an invalid email address and move to the next field, you can show an error message immediately. That way the user can correct every field before they submit the form.
If you only validate on the server, they have to submit the form, get an error message, and try to hunt down the problem.
(This pain can be eased by having the server re-render the form with the user's original input filled in, but client-side validation is still faster.)
You want to validate on the server side because you can protect against the malicious user, who can easily bypass your JavaScript and submit dangerous input to the server.
It is very dangerous to trust your UI. Not only can they abuse your UI, but they may not be using your UI at all, or even a browser. What if the user manually edits the URL, or runs their own Javascript, or tweaks their HTTP requests with another tool? What if they send custom HTTP requests from curl
or from a script, for example?
(This is not theoretical; eg, I worked on a travel search engine that re-submitted the user's search to many partner airlines, bus companies, etc, by sending POST
requests as if the user had filled each company's search form, then gathered and sorted all the results. Those companies' form JS was never executed, and it was crucial for us that they provide error messages in the returned HTML. Of course, an API would have been nice, but this was what we had to do.)
Not allowing for that is not only naive from a security standpoint, but also non-standard: a client should be allowed to send HTTP by whatever means they wish, and you should respond correctly. That includes validation.
Server side validation is also important for compatibility - not all users, even if they're using a browser, will have JavaScript enabled.
There are some validations that can't even be properly done in server-side application code, and are utterly impossible in client-side code, because they depend on the current state of the database. For example, "nobody else has registered that username", or "the blog post you're commenting on still exists", or "no existing reservation overlaps the dates you requested", or "your account balance still has enough to cover that purchase." Only the database can reliably validate data which depends on related data. Developers regularly screw this up, but PostgreSQL provides some good solutions.
Try this.
public class StopWatch {
private long startTime = 0;
private long stopTime = 0;
public StopWatch()
{
startTime = System.currentTimeMillis();
}
public void start() {
startTime = System.currentTimeMillis();
}
public void stop() {
stopTime = System.currentTimeMillis();
System.out.println("StopWatch: " + getElapsedTime() + " milliseconds.");
System.out.println("StopWatch: " + getElapsedTimeSecs() + " seconds.");
}
/**
* @param process_name
*/
public void stop(String process_name) {
stopTime = System.currentTimeMillis();
System.out.println(process_name + " StopWatch: " + getElapsedTime() + " milliseconds.");
System.out.println(process_name + " StopWatch: " + getElapsedTimeSecs() + " seconds.");
}
//elaspsed time in milliseconds
public long getElapsedTime() {
return stopTime - startTime;
}
//elaspsed time in seconds
public double getElapsedTimeSecs() {
double elapsed;
elapsed = ((double)(stopTime - startTime)) / 1000;
return elapsed;
}
}
Usage:
StopWatch watch = new StopWatch();
// do something
watch.stop();
Console:
StopWatch: 143 milliseconds.
StopWatch: 0.143 seconds.
Previously, you would do this through NPAPI plugins.
However, Google is now phasing out NPAPI for Chrome, so the preferred way to do this is using the native messaging API. The external application would have to register a native messaging host in order to exchange messages with your application.
The best way I found is using keydown
( the keyup
doesn't work well for me).
Note: I also disabled the form submit because usually when you like to do some actions when pressing Enter Key the only think you do not like is to submit the form :)
$('input').keydown( function( event ) {
if ( event.which === 13 ) {
// Do something
// Disable sending the related form
event.preventDefault();
return false;
}
});
Read one character at a time (using getc(stdin)
) and grow the string (realloc
) as you go.
Here's a function I wrote some time ago. Note it's intended only for text input.
char *getln()
{
char *line = NULL, *tmp = NULL;
size_t size = 0, index = 0;
int ch = EOF;
while (ch) {
ch = getc(stdin);
/* Check if we need to stop. */
if (ch == EOF || ch == '\n')
ch = 0;
/* Check if we need to expand. */
if (size <= index) {
size += CHUNK;
tmp = realloc(line, size);
if (!tmp) {
free(line);
line = NULL;
break;
}
line = tmp;
}
/* Actually store the thing. */
line[index++] = ch;
}
return line;
}
To add the myriad of other potential sources... I had updated all the libraries in my project's lib
folder but then Eclipse "helpfully" reinstalled all the original libraries. There was no longer any reference inside Eclipse to these libraries but the external dex-maker program just grabbed all the files in the lib
directory and thus got two versions of several library .jar
files.
git status
identified the new files and git clean -f
got rid of them for me (though I sometimes had to wait or restart Eclipse on Windows because it still had the files open from the copy).
Wrap it in an unused function:
.f = function() {
## unwanted code here:
}
try this new DecimalFormat("#.00");
update:
double angle = 20.3034;
DecimalFormat df = new DecimalFormat("#.00");
String angleFormated = df.format(angle);
System.out.println(angleFormated); //output 20.30
Your code wasn't using the decimalformat correctly
The 0 in the pattern means an obligatory digit, the # means optional digit.
update 2: check bellow answer
If you want 0.2677
formatted as 0.27
you should use new DecimalFormat("0.00");
otherwise it will be .27
I'm writing an answer to increase visibility to the actual syntax that solves the problem. Unfortunately, what someone might see as trivial can become a very significant headache to someone looking for a simple answer to a reasonable question.
Put the following into the file "Makefile".
MY_VAR := $(shell python -c 'import sys; print int(sys.version_info >= (2,5))')
all:
@echo MY_VAR IS $(MY_VAR)
The behavior you would like to see is the following (assuming you have recent python installed).
make
MY_VAR IS 1
If you copy and paste the above text into the Makefile, will you get this? Probably not. You will probably get an error like what is reported here:
makefile:4: *** missing separator. Stop
Why: Because although I personally used a genuine tab, Stack Overflow (attempting to be helpful) converts my tab into a number of spaces. You, frustrated internet citizen, now copy this, thinking that you now have the same text that I used. The make command, now reads the spaces and finds that the "all" command is incorrectly formatted. So copy the above text, paste it, and then convert the whitespace before "@echo" to a tab, and this example should, at last, hopefully, work for you.
You cannot guarantee that the automatically-generated WSDL will match the WSDL from which you create the service interface.
In your scenario, you should place the WSDL file on your web site somewhere, and have consumers use that URL. You should disable the Documentation
protocol in the web.config so that "?wsdl" does not return a WSDL. See <protocols>
Element.
Also, note the first paragraph of that article:
This topic is specific to a legacy technology. XML Web services and XML Web service clients should now be created using Windows Communication Foundation (WCF).
Well, in obvious cases like that, you can always tell PHP to suppress messages by using "@" in front of the function.
$monthly_index = @array_shift(unpack('H*', date('m/Y')));
It may not be one of the best programming practices to suppress all errors this way, but in certain cases (like this one) it comes handy and is acceptable.
As result, I am sure your friend 'system administrator' will be pleased with a less polluted error.log
.
I've used Flexcel in the past and it was great. But this was more for programmatically creating and updating excel worksheets.
If none of the above works, try using this in web.config or app.config:

Not core Java, and not generic-ified, but the popular Jakarta commons collections library has some useful abstractions for this sort of task. Specifically, have a look at the collect methods on
Something to consider if you are already using commons collections in your project.
Just to add a note that Google Chrome browser has origin attribute for the location. which gives you the entire domain from protocol to the port number as shown in the below screenshot.
While existing answers definitely solve the purpose, if your'e looking to replicate nested directory structure under two different subdirectories, then you can do this
mkdir -p {main,test}/{resources,scala/com/company}
It will create following directory structure under the directory from where it is invoked
+-- main
¦ +-- resources
¦ +-- scala
¦ +-- com
¦ +-- company
+-- test
+-- resources
+-- scala
+-- com
+-- company
The example was taken from this link for creating SBT directory structure
var geturl;
geturl = $.ajax({
type: "GET",
url: 'http://....',
success: function () {
alert("done!"+ geturl.getAllResponseHeaders());
}
});
There's two possible questions here: how can you iterate over those variables simultaneously, or how can you loop over their combination.
Fortunately, there's simple answers to both. First case, you want to use zip
.
x = [1, 2, 3]
y = [4, 5, 6]
for i, j in zip(x, y):
print(str(i) + " / " + str(j))
will output
1 / 4
2 / 5
3 / 6
Remember that you can put any iterable in zip
, so you could just as easily write your exmple like:
for i, j in zip(range(x), range(y)):
# do work here.
Actually, just realised that won't work. It would only iterate until the smaller range ran out. In which case, it sounds like you want to iterate over the combination of loops.
In the other case, you just want a nested loop.
for i in x:
for j in y:
print(str(i) + " / " + str(j))
gives you
1 / 4
1 / 5
1 / 6
2 / 4
2 / 5
...
You can also do this as a list comprehension.
[str(i) + " / " + str(j) for i in range(x) for j in range(y)]
Hope that helps.
In Python 3 this can be done in 2 steps:
datetime
objectdatetime
object by 1000 to convert it to milliseconds.For example like this:
from datetime import datetime
dt_obj = datetime.strptime('20.12.2016 09:38:42,76',
'%d.%m.%Y %H:%M:%S,%f')
millisec = dt_obj.timestamp() * 1000
print(millisec)
Output:
1482223122760.0
strptime
accepts your timestring and a format string as input. The timestring (first argument) specifies what you actually want to convert to a datetime
object. The format string (second argument) specifies the actual format of the string that you have passed.
Here is the explanation of the format specifiers from the official documentation:
%d
- Day of the month as a zero-padded decimal number.%m
- Month as a zero-padded decimal number.%Y
- Year with century as a decimal number%H
- Hour (24-hour clock) as a zero-padded decimal number.%M
- Minute as a zero-padded decimal number.%S
- Second as a zero-padded decimal number.%f
- Microsecond as a decimal number, zero-padded on the left.Starting Python 3.8
, the standard library provides the NormalDist
object as part of the statistics
module.
The NormalDist
object can be built from a set of data with the NormalDist.from_samples
method and provides access to its mean (NormalDist.mean
) and standard deviation (NormalDist.stdev
):
from statistics import NormalDist
# data = [0.7237248252340628, 0.6402731706462489, -1.0616113628912391, -1.7796451823371144, -0.1475852030122049, 0.5617952240065559, -0.6371760932160501, -0.7257277223562687, 1.699633029946764, 0.2155375969350495, -0.33371076371293323, 0.1905125348631894, -0.8175477853425216, -1.7549449090704003, -0.512427115804309, 0.9720486316086447, 0.6248742504909869, 0.7450655841312533, -0.1451632129830228, -1.0252663611514108]
norm = NormalDist.from_samples(data)
# NormalDist(mu=-0.12836704320073597, sigma=0.9240861018557649)
norm.mean

KeyStore Explorer is an open source GUI replacement for the Java command-line utilities keytool and jarsigner. It does openssl/pkcs12 as well.
I tried using phyatt's AspectRatioPixmapLabel
class, but experienced a few problems:
QLabel::setPixmap(...)
inside the resizeEvent method, because QLabel
actually calls updateGeometry
inside setPixmap
, which may trigger resize events...heightForWidth
seemed to be ignored by the containing widget (a QScrollArea
in my case) until I started setting a size policy for the label, explicitly calling policy.setHeightForWidth(true)
QLabel
's implementation of minimumSizeHint()
does some magic for labels containing text, but always resets the size policy to the default one, so I had to overwrite itThat said, here is my solution. I found that I could just use setScaledContents(true)
and let QLabel
handle the resizing.
Of course, this depends on the containing widget / layout honoring the heightForWidth
.
aspectratiopixmaplabel.h
#ifndef ASPECTRATIOPIXMAPLABEL_H
#define ASPECTRATIOPIXMAPLABEL_H
#include <QLabel>
#include <QPixmap>
class AspectRatioPixmapLabel : public QLabel
{
Q_OBJECT
public:
explicit AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent = 0);
virtual int heightForWidth(int width) const;
virtual bool hasHeightForWidth() { return true; }
virtual QSize sizeHint() const { return pixmap()->size(); }
virtual QSize minimumSizeHint() const { return QSize(0, 0); }
};
#endif // ASPECTRATIOPIXMAPLABEL_H
aspectratiopixmaplabel.cpp
#include "aspectratiopixmaplabel.h"
AspectRatioPixmapLabel::AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent) :
QLabel(parent)
{
QLabel::setPixmap(pixmap);
setScaledContents(true);
QSizePolicy policy(QSizePolicy::Maximum, QSizePolicy::Maximum);
policy.setHeightForWidth(true);
this->setSizePolicy(policy);
}
int AspectRatioPixmapLabel::heightForWidth(int width) const
{
if (width > pixmap()->width()) {
return pixmap()->height();
} else {
return ((qreal)pixmap()->height()*width)/pixmap()->width();
}
}

404 is just the HTTP response code. On top of that, you can provide a response body and/or other headers with a more meaningful error message that developers will see.
Have a look at the helper class: Mage_Customer_Helper_Data
To simply get the customer name, you can write the following code:-
$customerName = Mage::helper('customer')->getCustomerName();
For more information about the customer's entity id, website id, email, etc. you can use getCustomer function. The following code shows what you can get from it:-
echo "<pre>"; print_r(Mage::helper('customer')->getCustomer()->getData()); echo "</pre>";
From the helper class, you can also get information about customer login url, register url, logout url, etc.
From the isLoggedIn function in the helper class, you can also check whether a customer is logged in or not.

Assume that, if you want to remove NAT rules,
List the appended IPtables using the command below,
# sudo iptables -L -t nat -v
Chain PREROUTING (policy ACCEPT 18 packets, 1382 bytes)
pkts bytes target prot opt in out source destination
7 420 DNAT tcp -- any any anywhere saltmaster tcp dpt:http to:172.31.5.207:80
0 0 DNAT tcp -- eth0 any anywhere anywhere tcp dpt:http to:172.31.5.207:8080
If you would like to remove the nat rule from the IPtables, just execute the command,
# sudo iptables -F -t nat -v
Flushing chain `PREROUTING'
Flushing chain `INPUT'
Flushing chain `OUTPUT'
Flushing chain `POSTROUTING'
Then, you can verify that,
# sudo iptables -L -t nat -v
I have also faced the problem. In the php file, I have written following code where there was some space before php start tag
<?php
namespace App\Controller;
when I remove that space, it solved.
how do I programmatically add an event to the user's calendar?
Which calendar?
Is there a common API they all share?
No, no more than there is a "common API they all share" for Windows calendar apps. There are some common data formats (e.g., iCalendar) and Internet protocols (e.g., CalDAV), but no common API. Some calendar apps don't even offer an API.
If there are specific calendar applications you wish to integrate with, contact their developers and determine if they offer an API. So, for example, the Calendar application from the Android open source project, that Mayra cites, offers no documented and supported APIs. Google has even explicitly told developers to not use the techniques outlined in the tutorial Mayra cites.
Another option is for you to add events to the Internet calendar in question. For example, the best way to add events to the Calendar application from the Android open source project is to add the event to the user's Google Calendar via the appropriate GData APIs.
UPDATE
Android 4.0 (API Level 14) added a CalendarContract
ContentProvider
.
My PHP is a little rusty, but I believe you're looking for indexed assignment. Simply use:
$catList[$row["datasource_id"]] = $row["title"];
In PHP arrays are actually maps, where the keys can be either integers or strings. Check out PHP: Arrays - Manual for more information.
If post data is malformed, $_POST will not contain anything. Yet, php://input will have the malformed string.
For example there is some ajax applications, that do not form correct post key-value sequence for uploading a file, and just dump all the file as post data, without variable names or anything. $_POST will be empty, $_FILES empty also, and php://input will contain exact file, written as a string.
I even run the command prompt as Administrator but it didn't work for me with the below error.
'keytool' is not recognized as an internal or external command,
operable program or batch file.
If the path to the keytool is not in your System paths then you will need to use the full path to use the keytool, which is
C:\Program Files\Java\jre<version>\bin
So, the command should be like
"C:\Program Files\Java\jre<version>\bin\keytool.exe" -importcert -alias certificateFileAlias -file CertificateFileName.cer -keystore cacerts
that worked for me.
It depends on what you are after in the Dictionary
Models.TestModels obj = new Models.TestModels();
foreach (var keyValuPair in obj.sp)
{
// KeyValuePair<int, dynamic>
}
foreach (var key in obj.sp.Keys)
{
// Int
}
foreach (var value in obj.sp.Values)
{
// dynamic
}
yes you can, just set the NODE_PATH env variable :
export NODE_PATH='yourdir'/node_modules
According to the doc :
If the NODE_PATH environment variable is set to a colon-delimited list of absolute paths, then node will search those paths for modules if they are not found elsewhere. (Note: On Windows, NODE_PATH is delimited by semicolons instead of colons.)
Additionally, node will search in the following locations:
1: $HOME/.node_modules
2: $HOME/.node_libraries
3: $PREFIX/lib/node
Where $HOME is the user's home directory, and $PREFIX is node's configured node_prefix.
These are mostly for historic reasons. You are highly encouraged to place your dependencies locally in node_modules folders. They will be loaded faster, and more reliably.
This is my answer
#include<stdio.h>
int main()
{int mat[100][100];
int row,column,i,j;
printf("enter how many row and colmn you want:\n \n");
scanf("%d",&row);
scanf("%d",&column);
printf("enter the matrix:");
for(i=0;i<row;i++){
for(j=0;j<column;j++){
scanf("%d",&mat[i][j]);
}
printf("\n");
}
for(i=0;i<row;i++){
for(j=0;j<column;j++){
printf("%d \t",mat[i][j]);}
printf("\n");}
}
I just choose an approximate value for the row and column. My selected row or column will not cross the value.and then I scan the matrix element then make it in matrix size.
In Swift 4.1 and Xcode 9.4.1
Simple answer is...
//To call function after 5 seconds time
DispatchQueue.main.asyncAfter(deadline: .now() + 5.0) {
//Here call your function
}
The simplest command which can give you what you need but some other good info too is:
hostnamectl
If you want to allow every bot to crawl everything, this is the best way to specify it in your robots.txt:
User-agent: *
Disallow:
Note that the Disallow
field has an empty value, which means according to the specification:
Any empty value, indicates that all URLs can be retrieved.
Your way (with Allow: /
instead of Disallow:
) works, too, but Allow
is not part of the original robots.txt specification, so it’s not supported by all bots (many popular ones support it, though, like the Googlebot). That said, unrecognized fields have to be ignored, and for bots that don’t recognize Allow
, the result would be the same in this case anyway: if nothing is forbidden to be crawled (with Disallow
), everything is allowed to be crawled.
However, formally (per the original spec) it’s an invalid record, because at least one Disallow
field is required:
At least one Disallow field needs to be present in a record.
Didn't work for me:
ng serve --watch
Try :
sudo ng serve
this worked for me!
There's also a package called bit
that is specifically designed for fast boolean operations. It's especially useful if you have large vectors or need to do many boolean operations.
z <- sample(c(TRUE, FALSE), 1e8, rep = TRUE)
system.time({
sum(z) # 0.170s
})
system.time({
bit::sum.bit(z) # 0.021s, ~10x improvement in speed
})
To conditionally check the length of the string, use CASE
.
SELECT CASE WHEN LEN(comments) <= 60
THEN comments
ELSE LEFT(comments, 60) + '...'
END As Comments
FROM myView
Yes you can, set the position: relative
for the container and position: absolute
for the help_panel
I guess this is what you're trying to write
grep myText $(find .)
and this may be something else helpful if you want to find the files grep hit
grep myText $(find .) | cut -d : -f 1 | sort | uniq
this will word definitely. i use this function for myself as well.
public static bool isFormOpen(Form formm)
{
foreach (Form OpenForm in Application.OpenForms)
{
if (OpenForm.Name == formm.Name)
{
return true;
}
}
return false;
}
Simply pass your data frame into the following function:
data_types <- function(frame) {
res <- lapply(frame, class)
res_frame <- data.frame(unlist(res))
barplot(table(res_frame), main="Data Types", col="steelblue", ylab="Number of Features")
}
to produce a plot of all data types in your data frame. For the iris dataset we get the following:
data_types(iris)
var q = from s in db.Serials
group s by s.Serial_Number into g
select new {Serial_Number = g.Key, MaxUid = g.Max(s => s.uid) }
REQUIREMENTS files.
Seriously, I use this in conjunction with virtualenv every day.
QUICK DEPENDENCY MANAGEMENT TUTORIAL, FOLKS
Requirements files allow you to create a snapshot of all packages that have been installed through pip. By encapsulating those packages in a virtualenvironment, you can have your codebase work off a very specific set of packages and share that codebase with others.
From Heroku's documentation https://devcenter.heroku.com/articles/python
You create a virtual environment, and set your shell to use it. (bash/*nix instructions)
virtualenv env
source env/bin/activate
Now all python scripts run with this shell will use this environment's packages and configuration. Now you can install a package locally to this environment without needing to install it globally on your machine.
pip install flask
Now you can dump the info about which packages are installed with
pip freeze > requirements.txt
If you checked that file into version control, when someone else gets your code, they can setup their own virtual environment and install all the dependencies with:
pip install -r requirements.txt
Any time you can automate tedium like this is awesome.
You appear to have a heredoc
containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc
:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF
or if BUILDING
is $2
in your script:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF
If your file.sql
had an exit
at the end then it would be even simpler as you wouldn't need the heredoc
:
sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2
In your SQL you can then refer to the position parameters using substitution variables:
...
}',SEM_Models('&1'),NULL,
...
The &1
will be replaced with the first value passed to the SQL script, BUILDING
; because that is a string it still needs to be enclosed in quotes. You might want to set verify off
to stop if showing you the substitutions in the output.
You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1
, the second is &2
, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF
or:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF
If total_count
is being passed to your shell script then just use its positional parameter, $4
or whatever. And your SQL would then be:
SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:
define MY_ALIAS = &1
define MY_MODEL = &2
SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
From your separate question, maybe you just wanted:
SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
... so the alias will be the same value you're querying on (the value in $2
, or BUILDING
in the original part of the answer). You can refer to a substitution variable as many times as you want.
That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:
select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT
If you set pages 0
and set heading off
, your repeated calls might appear in a neat list. You might also need to set tab off
and possibly use rpad('&1', 20)
or similar to make that column always the same width. Or get the results as CSV with:
select '&1' ||','|| COUNT(*)
Depends what you're using the results for...
You had thead
in your selector, but there is no thead
in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr
class to the th
, not vice-versa (although your comment seems to contradict what you wrote up above).
$('tr th').each(function(index){ if($('tr td').eq(index).attr('class') != ''){ // get the class of the td var tdClass = $('tr td').eq(index).attr('class'); // add it to this th $(this).addClass(tdClass ); } });
It might be late, but for any other person who may get such an issue in future, for any connections you want to make to the server (in this case the machine that hosts the web application, regardless if it is iis or xampp) you need to allow connection or traffic through the specific port that will be used in the firewall
1. Go to Windows Firewall -> Advanced settings
2. Click Inbound Rules -> Then New Rule
3. Select Port -> Next
4. Specific local ports -> Add the Port you want to allow
5. Allow All Connections
6. Enter a name and a description for to help you remember later on

If you need to update user information for a specific user ID "x",
The ViewModel will initialize an instance of dbManager to access the database. The code should look like this:
@Entity
class User{
@PrimaryKey
String userId;
String username;
}
Interface UserDao{
//forUpdate
@Update
void updateUser(User user)
}
Class DbManager{
//AppDatabase gets the static object o roomDatabase.
AppDatabase appDatabase;
UserDao userDao;
public DbManager(Application application ){
appDatabase = AppDatabase.getInstance(application);
//getUserDao is and abstract method of type UserDao declared in AppDatabase //class
userDao = appDatabase.getUserDao();
}
public void updateUser(User user, boolean isUpdate){
new InsertUpdateUserAsyncTask(userDao,isUpdate).execute(user);
}
public static class InsertUpdateUserAsyncTask extends AsyncTask<User, Void, Void> {
private UserDao userDAO;
private boolean isInsert;
public InsertUpdateBrandAsyncTask(BrandDAO userDAO, boolean isInsert) {
this. userDAO = userDAO;
this.isInsert = isInsert;
}
@Override
protected Void doInBackground(User... users) {
if (isInsert)
userDAO.insertBrand(brandEntities[0]);
else
//for update
userDAO.updateBrand(users[0]);
//try {
// Thread.sleep(1000);
//} catch (InterruptedException e) {
// e.printStackTrace();
//}
return null;
}
}
}
Class UserViewModel{
DbManager dbManager;
public UserViewModel(Application application){
dbmanager = new DbMnager(application);
}
public void updateUser(User user, boolean isUpdate){
dbmanager.updateUser(user,isUpdate);
}
}
Now in your activity or fragment initialise your UserViewModel like this:
UserViewModel userViewModel = ViewModelProviders.of(this).get(UserViewModel.class);
Then just update your user item this way, suppose your userId is 1122 and userName is "xyz" which has to be changed to "zyx".
Get an userItem of id 1122 User object
User user = new user(); if(user.getUserId() == 1122){ user.setuserName("zyx"); userViewModel.updateUser(user); }
This is a raw code, hope it helps you.
Happy coding
Give full path as input. Avoid relative paths.

What I normally do, similar to answer one:
var response = await httpClient.GetAsync(completeURL); // http://192.168.0.1:915/api/Controller/Object
if (response.IsSuccessStatusCode == true)
{
string res = await response.Content.ReadAsStringAsync();
var content = Json.Deserialize<Model>(res);
// do whatever you need with the JSON which is in 'content'
// ex: int id = content.Id;
Navigate();
return true;
}
else
{
await JSRuntime.Current.InvokeAsync<string>("alert", "Warning, the credentials you have entered are incorrect.");
return false;
}
Where 'model' is your C# model class.
You can use android:stopWithTask="false"
in manifest as bellow, This means even if user kills app by removing it from tasklist, your service won't stop.
<service android:name=".service.StickyService"
android:stopWithTask="false"/>
Previous messages recommended basically how to build a paging by yourself. If you are like me, and prefer a finished directive, I just found a great one called ngTable. It supports sorting, filtering and pagination.
It is a very clean solution, all you need in your view:
<table ng-table="tableParams" class="table">
<tr ng-repeat="user in $data">
<td data-title="'Name'" sortable="'name'">
{{user.name}}
</td>
<td data-title="'Age'" sortable="'age'">
{{user.age}}
</td>
</tr>
</table>
And in controller:
$scope.tableParams = new ngTableParams({
page: 1, // show first page
count: 10, // count per page
sorting: {
name: 'asc' // initial sorting
}
}, {
total: data.length, // length of data
getData: function($defer, params) {
// use build-in angular filter
var orderedData = params.sorting() ?
$filter('orderBy')(data, params.orderBy()) :
data;
var start = (params.page() - 1) * params.count();
var end = params.page() * params.count();
$defer.resolve(orderedData.slice( start, end));
}
});
Link to GitHub: https://github.com/esvit/ng-table/
The function add() returns the old date, but changes the original date :)
startdate = "20.03.2014";
var new_date = moment(startdate, "DD.MM.YYYY");
new_date.add(5, 'days');
alert(new_date);
The following batch code returns the components of the current date in a locale-independent manner and stores day, month and year in the variables CurrDay
, CurrMonth
and CurrYear
, respectively:
for /F "skip=1 delims=" %%F in ('
wmic PATH Win32_LocalTime GET Day^,Month^,Year /FORMAT:TABLE
') do (
for /F "tokens=1-3" %%L in ("%%F") do (
set CurrDay=0%%L
set CurrMonth=0%%M
set CurrYear=%%N
)
)
set CurrDay=%CurrDay:~-2%
set CurrMonth=%CurrMonth:~-2%
echo Current day : %CurrDay%
echo Current month: %CurrMonth%
echo Current year :%CurrYear%
There are two nested for /F
loops to work around an issue with the wmic
command, whose output is in unicode format; using a single loop results in additional carriage-return characters which impacts proper variable expansion.
Since day and month may also consist of a single digit only, I prepended a leading zero 0
in the loop construct. Afterwards, the values are trimmed to always consist of two digits.
Vue2: if you only want to detect change on input blur (e.g. after press enter or click somewhere else) do (more info here)
<input @change="foo" v-model... >
If you wanna detect single character changes (during user typing) use
<input @keydown="foo" v-model... >
You can also use @keyup
and @input
events. If you wanna to pass additional parameters use in template e.g. @keyDown="foo($event, param1, param2)"

I faced a similar issue while copying a sheet to another workbook. I prefer to avoid using 'activesheet' though as it has caused me issues in the past. Hence I wrote a function to perform this inline with my needs. I add it here for those who arrive via google as I did:
The main issue here is that copying a visible sheet to the last index position results in Excel repositioning the sheet to the end of the visible sheets. Hence copying the sheet to the position after the last visible sheet sorts this issue. Even if you are copying hidden sheets.
Function Copy_WS_to_NewWB(WB As Workbook, WS As Worksheet) As Worksheet
'Creates a copy of the specified worksheet in the specified workbook
' Accomodates the fact that there may be hidden sheets in the workbook
Dim WSInd As Integer: WSInd = 1
Dim CWS As Worksheet
'Determine the index of the last visible worksheet
For Each CWS In WB.Worksheets
If CWS.Visible Then If CWS.Index > WSInd Then WSInd = CWS.Index
Next CWS
WS.Copy after:=WB.Worksheets(WSInd)
Set Copy_WS_to_NewWB = WB.Worksheets(WSInd + 1)
End Function
To use this function for the original question (ie in the same workbook) could be done with something like...
Set test = Copy_WS_to_NewWB(Workbooks(1), Workbooks(1).Worksheets(1))
test.name = "test sheet name"
EDIT 04/11/2020 from –user3598756 Adding a slight refactoring of the above code
Function CopySheetToWorkBook(targetWb As Workbook, shToBeCopied As Worksheet, copiedSh As Worksheet) As Boolean
'Creates a copy of the specified worksheet in the specified workbook
' Accomodates the fact that there may be hidden sheets in the workbook
Dim lastVisibleShIndex As Long
Dim iSh As Long
On Error GoTo SafeExit
With targetWb
'Determine the index of the last visible worksheet
For iSh = .Sheets.Count To 1 Step -1
If .Sheets(iSh).Visible Then
lastVisibleShIndex = iSh
Exit For
End If
Next
shToBeCopied.Copy after:=.Sheets(lastVisibleShIndex)
Set copiedSh = .Sheets(lastVisibleShIndex + 1)
End With
CopySheetToWorkBook = True
Exit Function
SafeExit:
End Function
other than using different (more descriptive?) variable names, the refactoring manily deals with:
turning the Function type into a `Boolean while including returned (copied) worksheet within function parameters list this, to let the calling Sub hande possible errors, like
Dim WB as Workbook: Set WB = ThisWorkbook ' as an example
Dim sh as Worksheet: Set sh = ActiveSheet ' as an example
Dim copiedSh as Worksheet
If CopySheetToWorkBook(WB, sh, copiedSh) Then
' go on with your copiedSh sheet
Else
Msgbox "Error while trying to copy '" & sh.Name & "'" & vbcrlf & err.Description
End If
having the For - Next loop stepping from last sheet index backwards and exiting at first visible sheet occurence, since we're after the "last" visible one

This is how I do it:
>>> import traceback
>>> try:
... int('k')
... except:
... var = traceback.format_exc()
...
>>> print var
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
ValueError: invalid literal for int() with base 10: 'k'
You should however take a look at the traceback documentation, as you might find there more suitable methods, depending to how you want to process your variable afterwards...
data="UTF-8 data"
udata=data.decode("utf-8")
data=udata.encode("latin-1","ignore")
Should do it.

I am fairly new to Docker. I was cleaning up some initial testing mess and was not able to remove a volume either. I had stopped all the running instances, performed a docker rmi -f $(docker image ls -q)
, but still received the Error response from daemon: unable to remove volume: remove uuid: volume is in use
.
I did a docker system prune
and it cleaned up what was needed to remove the last volume:
[0]$ docker system prune
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
- all build cache

You set the text to a field that was rendered in another instance of your activity residing in cash,say when it was landscape oriented. Then it was recreated due to some reason. You need to set the text in an unusual way by saving the string to SharedPreferences and force relaunch the activity using recreate(), say for mOutputText:
@Override
protected void onResume() {
super.onResume();
String sLcl=mPreferences.getString("response","");
if(!sLcl.isEmpty()){
mOutputText.setText(sLcl);
mPreferences.edit().putString("response","").commit();
}
}
private void changeText() {
mPreferences.edit().putString("response",responseText).commit();
recreate();
}
@Override
protected void onActivityResult(
int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case CAPTURE_MEDIA_RESULT_CODE:
if (null == data || null == data.getData()) {
showMessage("Sorry. You didn't save any video");
} else {
videoUri = data.getData();
mProgress = new ProgressDialog(this);
mProgress.setMessage("Uploading onYoutube ...");
authorizeIt();// SAY YOU CALL THE changeText() at the end of this method
}
break;

Nobody has proposed the Docker Python API yet. Docker API solution to get IP Address is fairly simple.
*NIX based OS: docker api 3.7 (updated thanks to canadadry from the comments)
import docker
client = docker.DockerClient(base_url='unix://var/run/docker.sock')
x_container = client.containers(filters={"name":"x_container"})[0]
x_ip_addr = x_container["NetworkSettings"]["Networks"]["NETWORK_NAME"]["IPAddress"]
OS Agnostic: docker api 4.0.x (added thanks to pds from the comments)
import docker
client = docker.from_env()
container = client.containers.get(container_name)
vars( container )["attrs"]["NetworkSettings"]["Networks"]["<NETWORK_NAME>"]["IPAddress"]
Wasn't too hard to find, but is useful. additionally this can be easily modified to find all IP's assigned to a container on various networks.
I sometimes like using the array_reduce() function to carry out the search. It's similar to array_filter() but does not affect the searched array, allowing you to carry out multiple searches on the same array of objects.
$haystack = array($obj1, $obj2, ...); //some array of objects
$needle = 'looking for me?'; //the value of the object's property we want to find
//carry out the search
$search_results_array = array_reduce(
$haystack,
function($result_array, $current_item) use ($needle){
//Found the an object that meets criteria? Add it to the the result array
if ($current_item->someProperty == $needle){
$result_array[] = $current_item;
}
return $result_array;
},
array() //initially the array is empty (i.e.: item not found)
);
//report whether objects found
if (count($search_results_array) > 0){
echo "found object(s): ";
print_r($search_results_array[0]); //sample object found
} else {
echo "did not find object(s): ";
}

I don't know Mathematica . . . too bad. But I like the answer above, for the most part.
Still there is a major flaw in relying on the stripes alone to glean the answer (I personally don't have a problem with one manual adjustment). There is an example (listed by Brett Champion, here) presented which shows that they, at times, break up the shirt pattern. So then it becomes a more complex pattern.
I would try an approach of shape id and colors, along with spacial relations. Much like face recognition, you could look for geometric patterns at certain ratios from each other. The caveat is that usually one or more of those shapes is occluded.
Get a white balance on the image, and red a red balance from the image. I believe Waldo is always the same value/hue, but the image may be from a scan, or a bad copy. Then always refer to an array of the colors that Waldo actually is: red, white, dark brown, blue, peach, {shoe color}.
There is a shirt pattern, and also the pants, glasses, hair, face, shoes and hat that define Waldo. Also, relative to other people in the image, Waldo is on the skinny side.
So, find random people to obtain an the height of people in this pic. Measure the average height of a bunch of things at random points in the image (a simple outline will produce quite a few individual people). If each thing is not within some standard deviation from each other, they are ignored for now. Compare the average of heights to the image's height. If the ratio is too great (e.g., 1:2, 1:4, or similarly close), then try again. Run it 10(?) of times to make sure that the samples are all pretty close together, excluding any average that is outside some standard deviation. Possible in Mathematica?
This is your Waldo size. Walso is skinny, so you are looking for something 5:1 or 6:1 (or whatever) ht:wd. However, this is not sufficient. If Waldo is partially hidden, the height could change. So, you are looking for a block of red-white that ~2:1. But there has to be more indicators.
Any of those could apply. These are also negative checks against similar people in the pic -- e.g., #2 negates wearing a red-white apron (too close to shoes), #5 eliminates light colored hair. Also, shape is only one indicator for each of these tests . . . color alone within the specified distance can give good results.
This will narrow down the areas to process.
Storing these results will produce a set of areas that should have Waldo in it. Exclude all other areas (e.g., for each area, select a circle twice as big as the average person size), and then run the process that @Heike laid out with removing all but red, and so on.
Any thoughts on how to code this?
Edit:
Thoughts on how to code this . . . exclude all areas but Waldo red, skeletonize the red areas, and prune them down to a single point. Do the same for Waldo hair brown, Waldo pants blue, Waldo shoe color. For Waldo skin color, exclude, then find the outline.
Next, exclude non-red, dilate (a lot) all the red areas, then skeletonize and prune. This part will give a list of possible Waldo center points. This will be the marker to compare all other Waldo color sections to.
From here, using the skeletonized red areas (not the dilated ones), count the lines in each area. If there is the correct number (four, right?), this is certainly a possible area. If not, I guess just exclude it (as being a Waldo center . . . it may still be his hat).
Then check if there is a face shape above, a hair point above, pants point below, shoe points below, and so on.
No code yet -- still reading the docs.
This worked for me,
CREATE TABLE newtable LIKE oldtable;
Replicates newtable with old table
INSERT newtable SELECT * FROM oldtable
;
Copies all the row data to new table.
Thank you
All these answers are nice however when thinking about it....
Sometimes the most simple approach without sophistication will do the trick quicker and with no special functions.
We first set the arrays:
$arr1 = Array(
"cod" => ddd,
"denum" => ffffffffffffffff,
"descr" => ggggggg,
"cant" => 3
);
$arr2 = Array
(
"cod" => fff,
"denum" => dfgdfgdfgdfgdfg,
"descr" => dfgdfgdfgdfgdfg,
"cant" => 33
);
Then we add them to the new array :
$newArr[] = $arr1;
$newArr[] = $arr2;
Now lets see our new array with all the keys:
print_r($newArr);
There's no need for sql or special functions to build a new multi-dimensional array.... don't use a tank to get to where you can walk.
I've seen this error a few times too, and I've always been able to solve it by correctly identifying the project's module settings. In IntelliJ, right-click on the top level project -> "Open Module Settings". This should open up a window with the entire project structure and content identified as "Source Folders", "Test Source Folders", etc. Make sure these are correctly set. For the "Source Folders", ensure that the folder is your src/ or src/java (or whatever your source language is), as the case may be
You should use the location.reload(true)
, which will release the cache for that specific page and force the page to load as a NEW page.
The true
parameter forces the page to release it's cache.
GCC offers
__attribute__((constructor))
https://gcc.gnu.org/onlinedocs/gcc-4.7.0/gcc/Function-Attributes.html
Tag a static method with this attribute and it will run on module load, before main().
& - (Condition 1 & Condition 2): checks both cases even if first one is false
&& - (Condition 1 && Condition 2): dosen't bother to check second case if case one is false
&& - operator will make your code run faster, professionally & is rarely used
| - (Condition 1 | Condition 2): checks both cases even if case 1 is true
|| - (Condition 1 || Condition 2): dosen't bother to check second case if first one is true
|| - operator will make your code run faster, professionally | is rarely used
Another advantage of using the '[[' operator is that it works both with data.frame and data.table. So if the function has to be made running for both data.frame and data.table, and you want to extract a column from it as a vector then
data[["column_name"]]
is best.
This worked for me!
split('.')[-1]
Will separate the filename suffix (*.xxx) so using if help to check it

objectAs the other answers point out, once the resources are inside a jar file, things get really ugly. In our case, this solution:
https://stackoverflow.com/a/13227570/516188
works very well in the tests (since when the tests are run the code is not packed in a jar file), but doesn't work when the app actually runs normally. So what I've done is... I hardcode the list of the files in the app, but I have a test which reads the actual list from disk (can do it since that works in tests) and fails if the actual list doesn't match with the list the app returns.
That way I have simple code in my app (no tricks), and I'm sure I didn't forget to add a new entry in the list thanks to the test.
Are you trying to pass the command line arguments to the program AS you launch it? I am working on something right now that does exactly this, and it was a lot simpler than I thought. If I go into the command line, and type
C:\folder\app.exe/xC:\folder\file.txt
then my application launches, and creates a file in the specified directory with the specified name.
I wanted to do this through a Powershell script on a remote machine, and figured out that all I needed to do was put
$s = New-PSSession -computername NAME -credential LOGIN
Invoke-Command -session $s -scriptblock {C:\folder\app.exe /xC:\folder\file.txt}
Remove-PSSession $s
(I have a bunch more similar commands inside the session, this is just the minimum it requires to run) notice the space between the executable, and the command line arguments. It works for me, but I am not sure exactly how your application works, or if that is even how you pass arguments to it.
*I can also have my application push the file back to my own local computer by changing the script-block to
C:\folder\app.exe /x"\\LocalPC\DATA (C)\localfolder\localfile.txt"
You need the quotes if your file-path has a space in it.
EDIT: actually, this brought up some silly problems with Powershell launching the application as a service or something, so I did some searching, and figured out that you can call CMD to execute commands for you on the remote computer. This way, the command is carried out EXACTLY as if you had just typed it into a CMD window on the remote machine. Put the command in the scriptblock into double quotes, and then put a cmd.exe /C before it. like this:
cmd.exe /C "C:\folder\app.exe/xC:\folder\file.txt"
this solved all of the problems that I have been having recently.
EDIT EDIT: Had more problems, and found a much better way to do it.
start-process -filepath C:\folder\app.exe -argumentlist "/xC:\folder\file.txt"
and this doesn't hang up your terminal window waiting for the remote process to end. Just make sure you have a way to terminate the process if it doesn't do that on it's own. (mine doesn't, required the coding of another argument)
I know this doesn't answer your question, but just to help other people. If you are trying to convert "true" or "false" strings to boolean:
Try Boolean.Parse
bool val = Boolean.Parse("true"); ==> true
bool val = Boolean.Parse("True"); ==> true
bool val = Boolean.Parse("TRUE"); ==> true
bool val = Boolean.Parse("False"); ==> false
bool val = Boolean.Parse("1"); ==> Exception!
bool val = Boolean.Parse("diffstring"); ==> Exception!
You are asking for the condition where all the conditions are true, so len of the frame is the answer, unless I misunderstand what you are asking
In [17]: df = DataFrame(randn(20,4),columns=list('ABCD'))
In [18]: df[(df['A']>0) & (df['B']>0) & (df['C']>0)]

After 13+ years of writing Python code and managing various packages, I came to the conclusion that DIY is maybe not the best approach.
I started using the pbr
package for dealing with versioning in my packages. If you are using git as your SCM, this will fit into your workflow like magic, saving your weeks of work (you will be surprised about how complex the issue can be).
As of today, pbr
is the 11th most used python package, and reaching this level didn't include any dirty tricks. It was only one thing -- fixing a common packaging problem in a very simple way.
pbr
can do more of the package maintenance burden, and is not limited to versioning, but it does not force you to adopt all its benefits.
So to give you an idea about how it looks to adopt pbr in one commit have a look switching packaging to pbr
Probably you would observed that the version is not stored at all in the repository. PBR does detect it from Git branches and tags.
No need to worry about what happens when you do not have a git repository because pbr does "compile" and cache the version when you package or install the applications, so there is no runtime dependency on git.
Here is the best solution I've seen so far and it also explains why:
Inside yourpackage/version.py
:
# Store the version here so:
# 1) we don't load dependencies by storing it in __init__.py
# 2) we can import it in setup.py for the same reason
# 3) we can import it into your module module
__version__ = '0.12'
Inside yourpackage/__init__.py
:
from .version import __version__
Inside setup.py
:
exec(open('yourpackage/version.py').read())
setup(
...
version=__version__,
...
If you know another approach that seems to be better let me know.
When you run the code
listoflists.append((list, list[0]))
You are not (as I think you expect) adding a copy of list
to the end of listoflists
. What you are doing is adding a reference to list
to the end of listoflists
. Thus, every time you update list
, it updates every reference to list
, which in this case, is every item in listoflists
What you could do instead is something like this:
listoflists = []
for i in range(1, 10):
listoflists.append((range(i), 0))
I'm a little confused why you are putting a WebView
into a ScrollView
in the first place. A WebView
has it's own built-in scrolling system.
Regarding your actual question, if you want the Scrollbar
to show up on top, you can use
view.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY) or
android:scrollbarStyle="insideOverlay"
I don't think that has any meaning in SQL. You might be looking at Prepared Statements in JDBC or something. In that case, the question marks are placeholders for parameters to the statement.
Simple PHP function to unzip. Please make sure you have zip extension installed on your server.
/**

* @return boolean
*/
function unzip(string $zip_file_path, string $extract_dir_path) {
$zip = new \ZipArchive;
$res = $zip->open($zip_file_path);
if ($res === TRUE) {
$zip->extractTo($extract_dir_path);
$zip->close();
return TRUE;
} else {
return FALSE;
}
}
string * and string& differ in a couple of ways. First of all, the pointer points to the address location of the data. The reference points to the data. If you had the following function:
int foo(string *param1);
You would have to check in the function declaration to make sure that param1 pointed to a valid location. Comparatively:
int foo(string ¶m1);
Here, it is the caller's responsibility to make sure the pointed to data is valid. You can't pass a "NULL" value, for example, int he second function above.
With regards to your second question, about the method return values being a reference, consider the following three functions:
string &foo();
string *foo();
string foo();
In the first case, you would be returning a reference to the data. If your function declaration looked like this:
string &foo()
{
string localString = "Hello!";
return localString;
}
You would probably get some compiler errors, since you are returning a reference to a string that was initialized in the stack for that function. On the function return, that data location is no longer valid. Typically, you would want to return a reference to a class member or something like that.
The second function above returns a pointer in actual memory, so it would stay the same. You would have to check for NULL-pointers, though.
Finally, in the third case, the data returned would be copied into the return value for the caller. So if your function was like this:
string foo()
{
string localString = "Hello!";
return localString;
}
You'd be okay, since the string "Hello" would be copied into the return value for that function, accessible in the caller's memory space.
The following bash function will change the time of any commit on the current branch.
Be careful not to use if you already pushed the commit or if you use the commit in another branch.
# rewrite_commit_date(commit, date_timestamp)
#
# !! Commit has to be on the current branch, and only on the current branch !!
#
# Usage example:
#
# 1. Set commit 0c935403 date to now:
#
# rewrite_commit_date 0c935403
#
# 2. Set commit 0c935403 date to 1402221655:
#
# rewrite_commit_date 0c935403 1402221655
#
rewrite_commit_date () {
local commit="$1" date_timestamp="$2"
local date temp_branch="temp-rebasing-branch"
local current_branch="$(git rev-parse --abbrev-ref HEAD)"
if [[ -z "$date_timestamp" ]]; then
date="$(date -R)"
else
date="$(date -R --date "@$date_timestamp")"
fi
git checkout -b "$temp_branch" "$commit"
GIT_COMMITTER_DATE="$date" git commit --amend --date "$date"
git checkout "$current_branch"
git rebase "$commit" --onto "$temp_branch"
git branch -d "$temp_branch"
}
Wxruby is a great framework, simple and clean. Try it or use glade with ruby (the simpliest option)
I was also in the same problem, check your build path in eclipse by Right Click on Project > build path > configure build path
Now check for Excluded Files, it should not have your file specified there by any means or by regex.

Late to the party, but another easy way of comparing NSDate objects is to convert them into primitive types which allows for easy use of '>' '<' '==' etc
eg.
if ([dateA timeIntervalSinceReferenceDate] > [dateB timeIntervalSinceReferenceDate]) {
//do stuff
}
timeIntervalSinceReferenceDate
converts the date into seconds since the reference date (1 January 2001, GMT). As timeIntervalSinceReferenceDate
returns a NSTimeInterval (which is a double typedef), we can use primitive comparators.
I tested in my version on PyCharm 2017.1.2. I used interactive (True) and show (block=True).
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
ts = pd.Series(np.random.randn(1000), index=pd.date_range('1//2000',periods=1000))
ts = ts.cumsum()
plt.interactive(True)
ts.plot()
plt.show(block=True)
The implode() function returns a string from the elements of an array.
<?php
$arr = array('Hello','World!','Beautiful','Day!');
echo implode(" ",$arr);
?>
Output: Hello World! Beautiful Day!
<?php
$arr = array('Hello','World!','Beautiful','Day!');
echo implode("|",$arr);
?>
Output: Hello|World!|Beautiful|Day!
I propose it remove the non printable characters like below instead of replacing it
private String removeNonBMPCharacters(final String input) {
StringBuilder strBuilder = new StringBuilder();
input.codePoints().forEach((i) -> {
if (Character.isSupplementaryCodePoint(i)) {
strBuilder.append("?");
} else {
strBuilder.append(Character.toChars(i));
}
});
return strBuilder.toString();
}
I am just adding another thing, In case you just want to check whether anything is created in JSONObject or not you can use length(), because by default when JSONObject is initialized and no key is inserted, it just has empty braces {}
and using has(String key) doesn't make any sense.
So you can directly write if (jsonObject.length() > 0)
and do your things.
Happy learning!

If an update query executes with values that match the current database record then $stmt->rowCount()
will return 0
for no rows were affected. If you have an if( rowCount() == 1 )
to test for success you will think the updated failed when it did not fail but the values were already in the database so nothing change.
$stmt->execute();
if( $stmt ) return "success";
This did not work for me when I tried to update a record with a unique key field that was violated. The query returned success but another query returns the old field value.
You need to wrap your method call into another one, where you do not throw checked exceptions. You can still throw anything that is a subclass of RuntimeException
.
A normal wrapping idiom is something like:
private void safeFoo(final A a) {
try {
a.foo();
} catch (Exception ex) {
throw new RuntimeException(ex);
}
}
(Supertype exception Exception
is only used as example, never try to catch it yourself)
Then you can call it with: as.forEach(this::safeFoo)
.
See this example :
<?php
echo "<div id='div1'>text</div>"
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title></title>
<script src="js/jquery1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#div1').click(function () {
alert('I clicked');
});
});
</script>
</head>

Assuming you are talking about the ActionEvent
class, then there is a big difference between the two methods.
getActionCommand()
gives you a String representing the action command. The value is component specific; for a JButton
you have the option to set the value with setActionCommand(String command)
but for a JTextField
if you don't set this, it will automatically give you the value of the text field. According to the javadoc this is for compatability with java.awt.TextField
.
getSource()
is specified by the EventObject
class that ActionEvent
is a child of (via java.awt.AWTEvent
). This gives you a reference to the object that the event came from.
Edit:
Here is a example. There are two fields, one has an action command explicitly set, the other doesn't. Type some text into each then press enter.
public class Events implements ActionListener {
private static JFrame frame;
public static void main(String[] args) {
frame = new JFrame("JTextField events");
frame.getContentPane().setLayout(new FlowLayout());
JTextField field1 = new JTextField(10);

I wrote a simple bash script to get around this stupid problem. Pass in the path to a named copy of your provision (downloaded from developer.apple.com) and it will identify the matching GUID-renamed file in your provision library:
#!/bin/bash
if [ -z "$1" ] ; then
echo -e "\nUsage: $0 <myprovision>\n"
exit
fi
if [ ! -f "$1" ] ; then
echo -e "\nFile not found: $1\n"
exit
fi
provisionpath="$HOME/Library/MobileDevice/Provisioning Profiles"
provisions=$( ls "$provisionpath" )
for i in $provisions ; do
match=$( diff "$1" "$provisionpath/$i" )
if [ "$match" = "" ] ; then
echo -e "\nmatch: $provisionpath/$i\n"

Create a new Java project in Eclipse. This will create a src folder (to contain your source files).
Also create a lib folder (the name isn't that important, but it follows standard conventions).
Copy the ./com/*
folders into the /src
folder (you can just do this using the OS, no need to do any fancy importing or anything from the Eclipse GUI).
Copy any dependencies (jar
files that your project itself depends on) into /lib
(note that this should NOT include the TGGL jar
- thanks to commenter Mike Deck for pointing out my misinterpretation of the OPs post!)
Copy the other TGGL stuff into the root project folder (or some other folder dedicated to licenses that you need to distribute in your final app)
Back in Eclipse, select the project you created in step 1, then hit the F5 key (this refreshes Eclipse's view of the folder tree with the actual contents.
The content of the /src
folder will get compiled automatically (with class files placed in the /bin file that Eclipse generated for you when you created the project). If you have dependencies (which you don't in your current project, but I'll include this here for completeness), the compile will fail initially because you are missing the dependency jar files
from the project classpath.
Finally, open the /lib
folder in Eclipse, right click
on each required jar file
and choose Build Path->Add
to build path.
That will add that particular jar to the classpath for the project. Eclipse will detect the change and automatically compile the classes that failed earlier, and you should now have an Eclipse project with your app in it.
You are subscripting a three-dimensional array myArray[10][10][10]
four times myArray[i][t][x][y]
. You will probably need to add another dimension to your array. Also consider a container like Boost.MultiArray, though that's probably over your head at this point.
redirect to ../
If the array is unsorted, there isn't really a better way (aside from using the above-mentioned indexOf, which I think amounts to the same thing). If the array is sorted, you can do a binary search, which works like this:
Binary search runs in time proportional to the logarithm of the length of the array, so it can be much faster than looking at each individual element.
If you want to rule out any problems with the else
part, try removing the else
and place the command on a new line. Like this:
IF EXIST D:\RPS_BACKUP\backups_temp\ goto tempexists
goto tempexistscontinue

follow steps in the image:
One hackish way to define an exit
method in context:
class Bar; def exit; end; end
This works because exit
in the initializer will be resolved as self.exit
1. In addition, this approach allows using the object after it has been created, as in: b = B.new
.
But really, one shouldn't be doing this: don't have exit
(or even puts
) there to begin with.
(And why is there an "infinite" loop and/or user input in an intiailizer? This entire problem is primarily the result of poorly structured code.)
1 Remember Kernel#exit is only a method. Since Kernel is included in every Object, then it's merely the case that exit
normally resolves to Object#exit
. However, this can be changed by introducing an overridden method as shown - nothing fancy.
If the image is proportionate then this code will fill the wrapper with image. If image is not in proportion then extra width/height will get cropped.

var height = $(this).height(); // Current image height
// Check if the current width is larger than the max
if (width > height && height < ReqHeight) {
$(this).css("min-height", ReqHeight); // Set new height

if (width > height && width < ReqWidth) {

Try using the REPLACE function:

-> 'WwWwWw.mysql.com'
Note that it is case sensitive.
If you are talking about browser javascript, you can not write data directly to local file for security reason. HTML 5 new API can only allow you to read files.
But if you want to write data, and enable user to download as a file to local. the following code works:
function download(strData, strFileName, strMimeType) {
var D = document,
A = arguments,
a = D.createElement("a"),
d = A[0],
n = A[1],
t = A[2] || "text/plain";
//build download link:
a.href = "data:" + strMimeType + "charset=utf-8," + escape(strData);
if (window.MSBlobBuilder) { // IE10
var bb = new MSBlobBuilder();
bb.append(strData);
return navigator.msSaveBlob(bb, strFileName);
} /* end if(window.MSBlobBuilder) */
if ('download' in a) { //FF20, CH19
a.setAttribute("download", n);
a.innerHTML = "downloading...";
D.body.appendChild(a);
setTimeout(function() {
var e = D.createEvent("MouseEvents");
e.initMouseEvent("click", true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
a.dispatchEvent(e);
D.body.removeChild(a);
}, 66);
return true;
}; /* end if('download' in a) */
//do iframe dataURL download: (older W3)
var f = D.createElement("iframe");
D.body.appendChild(f);
f.src = "data:" + (A[2] ? A[2] : "application/octet-stream") + (window.btoa ? ";base64" : "") + "," + (window.btoa ? window.btoa : escape)(strData);
setTimeout(function() {
D.body.removeChild(f);
}, 333);
return true;
}
to use it:
download('the content of the file', 'filename.txt', 'text/plain');
I had the same problem and, in my case, the problem was that python was looking for packages in some ordered locations, first of all the default computer one where default old packages are.
To check what your python is looking for you can do:
>>> import sys
>>> print '\n'.join(sys.path)
This was outputting the directory '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python' before pip or brew or port folders.
The simple solution is:
export PYTHONPATH="/Library/Python/2.7/site-packages:$PYTHONPATH"
This worked well for me, I advise you to add this line to your home bash_profile file for the next time. Remember that sys.path is built using the current working directory, followed by the directories in the PYTHONPATH environment variable. Then there are the installation-dependent default dirs.

List does not implement IBindingList
so the grid does not know about your new items.
Bind your DataGridView to a BindingList<T>
instead.
var list = new BindingList<Person>(persons);
myGrid.DataSource = list;
But I would even go further and bind your grid to a BindingSource
var list = new List<Person>()
{
new Person { Name = "Joe", },
new Person { Name = "Misha", },
};
var bindingList = new BindingList<Person>(list);
var source = new BindingSource(bindingList, null);
grid.DataSource = source;

Here is my implementation in java for your requirement. In the treeNode class i used generic array to store the tree data. we can also use arraylist or dynamic array to store the tree value.
public class TreeNode<T> {
private T value = null;
private TreeNode[] childrens = new TreeNode[100];
private int childCount = 0;
TreeNode(T value) {
this.value = value;
}
public TreeNode addChild(T value) {
TreeNode newChild = new TreeNode(value, this);
childrens[childCount++] = newChild;
return newChild;
}
static void traverse(TreeNode obj) {
if (obj != null) {
for (int i = 0; i < obj.childCount; i++) {
System.out.println(obj.childrens[i].value);
traverse(obj.childrens[i]);
}
}
return;
}
void printTree(TreeNode obj) {
System.out.println(obj.value);
traverse(obj);
}
}
And the client class for the above implementation.
public class Client {
public static void main(String[] args) {
TreeNode menu = new TreeNode("Menu");
TreeNode item = menu.addChild("Starter");
item = item.addChild("Veg");
item.addChild("Paneer Tikka");
item.addChild("Malai Paneer Tikka");
item = item.addChild("Non-veg");
item.addChild("Chicken Tikka");
item.addChild("Malai Chicken Tikka");

Whenever the Python interpreter reads a source file, it does two things:
it sets a few special variables like __name__
, and then
it executes all of the code found in the file.
Let's see how this works and how it relates to your question about the __name__
checks we always see in Python scripts.
Let's use a slightly different code sample to explore how imports and scripts work. Suppose the following is in a file called foo.py
.
# Suppose this is foo.py.
print("before import")
import math
print("before functionA")
def functionA():
print("Function A")
print("before functionB")
def functionB():
print("Function B {}".format(math.sqrt(100)))
print("before __name__ guard")
if __name__ == '__main__':
functionA()
functionB()
print("after __name__ guard")
When the Python interpreter reads a source file, it first defines a few special variables. In this case, we care about the __name__
variable.
When Your Module Is the Main Program
If you are running your module (the source file) as the main program, e.g.
python foo.py
the interpreter will assign the hard-coded string "__main__"
to the __name__
variable, i.e.
# It's as if the interpreter inserts this at the top
# of your module when run as the main program.
__name__ = "__main__"
When Your Module Is Imported By Another
On the other hand, suppose some other module is the main program and it imports your module. This means there's a statement like this in the main program, or in some other module the main program imports:
# Suppose this is in some other main program.
import foo
The interpreter will search for your foo.py
file (along with searching for a few other variants), and prior to executing that module, it will assign the name "foo"
from the import statement to the __name__
variable, i.e.
# It's as if the interpreter inserts this at the top
# of your module when it's imported from another module.
__name__ = "foo"
After the special variables are set up, the interpreter executes all the code in the module, one statement at a time. You may want to open another window on the side with the code sample so you can follow along with this explanation.
Always
It prints the string "before import"
(without quotes).
It loads the math
module and assigns it to a variable called math
. This is equivalent to replacing import math
with the following (note that __import__
is a low-level function in Python that takes a string and triggers the actual import):
# Find and load a module given its string name, "math",
# then assign it to a local variable called math.
math = __import__("math")
It prints the string "before functionA"
.
It executes the def
block, creating a function object, then assigning that function object to a variable called functionA
.
It prints the string "before functionB"
.
It executes the second def
block, creating another function object, then assigning it to a variable called functionB
.
It prints the string "before __name__ guard"
.
Only When Your Module Is the Main Program
__name__
was indeed set to "__main__"
and it calls the two functions, printing the strings "Function A"
and "Function B 10.0"
.Only When Your Module Is Imported by Another
__name__
will be "foo"
, not "__main__"
, and it'll skip the body of the if
statement.Always
"after __name__ guard"
in both situations.Summary
In summary, here's what'd be printed in the two cases:
# What gets printed if foo is the main program
before import
before functionA
before functionB
before __name__ guard
Function A
Function B 10.0
after __name__ guard
# What gets printed if foo is imported as a regular module
before import
before functionA
before functionB
before __name__ guard
after __name__ guard
You might naturally wonder why anybody would want this. Well, sometimes you want to write a .py
file that can be both used by other programs and/or modules as a module, and can also be run as the main program itself. Examples:
Your module is a library, but you want to have a script mode where it runs some unit tests or a demo.
Your module is only used as a main program, but it has some unit tests, and the testing framework works by importing .py
files like your script and running special test functions. You don't want it to try running the script just because it's importing the module.
Your module is mostly used as a main program, but it also provides a programmer-friendly API for advanced users.
Beyond those examples, it's elegant that running a script in Python is just setting up a few magic variables and importing the script. "Running" the script is a side effect of importing the script's module.
Question: Can I have multiple __name__
checking blocks? Answer: it's strange to do so, but the language won't stop you.
Suppose the following is in foo2.py
. What happens if you say python foo2.py
on the command-line? Why?
# Suppose this is foo2.py.
import os, sys; sys.path.insert(0, os.path.dirname(__file__)) # needed for some interpreters
def functionA():
print("a1")
from foo2 import functionB
print("a2")
functionB()
print("a3")
def functionB():
print("b")
print("t1")
if __name__ == "__main__":
print("m1")
functionA()
print("m2")
print("t2")
__name__
check in foo3.py
:# Suppose this is foo3.py.
import os, sys; sys.path.insert(0, os.path.dirname(__file__)) # needed for some interpreters
def functionA():
print("a1")
from foo3 import functionB
print("a2")
functionB()
print("a3")
def functionB():
print("b")
print("t1")
print("m1")
functionA()
print("m2")
print("t2")
# Suppose this is in foo4.py
__name__ = "__main__"
def bar():
print("bar")
print("before __name__ guard")
if __name__ == "__main__":
bar()
print("after __name__ guard")
var str = '';
for( var name in obj ) {
str += (name + '=' + obj[name] + '&');
}
str = str.slice(0,-1);
Give this a shot.

Git 1.8.2 features a new option ,--remote
, that will enable exactly this behavior. Running
git submodule update --rebase --remote
will fetch the latest changes from upstream in each submodule, rebase them, and check out the latest revision of the submodule. As the documentation puts it:
--remote
This option is only valid for the update command. Instead of using the superproject’s recorded SHA-1 to update the submodule, use the status of the submodule’s remote-tracking branch.
This is equivalent to running git pull
in each submodule, which is generally exactly what you want.

Windows has a concept of current directory for each drive. Because of that, "c:sourcedir"
means "sourcedir" inside the current C: directory, and you'll need to specify an absolute directory.
Any of these should work and give the same result, but I don't have a Windows VM fired up at the moment to double check:
"c:/sourcedir"
os.path.join("/", "c:", "sourcedir")
os.path.join("c:/", "sourcedir")

I could not access container IPs directly on Mac. I need to use localhost
with port forwarding, e.g. if the port is 8000, then http://localhost:8000
See https://docs.docker.com/docker-for-mac/networking/#known-limitations-use-cases-and-workarounds
The original answer was from: https://github.com/docker/for-mac/issues/2670#issuecomment-371249949
The main consideration that others are neglecting is that OP has stated that they cannot modify the HTML.
You can target what you need in the DOM then add classes dynamically with javascript. Then style as you need.
In an example that I made, I targeted all <p>
elements with jQuery and wrapped it with a div with a class of "colored"
$( "p" ).wrap( "<div class='colored'></div>" );
Then in my CSS i targeted the <p>
and gave it the background color and changed to display: inline
.colored p {
display: inline;
background: green;
}
By setting the display to inline you lose some of the styling that it would normally inherit. So make sure that you target the most specific element and style the container to fit the rest of your design. This is just meant as a working starting point. Use carefully. Working demo on CodePen
a = 0.000006;
b = 6;
c = a/b;
textbox.Text = c.ToString("0.000000");
As you requested:
textbox.Text = c.ToString("0.######");
This will only display out to the 6th decimal place if there are 6 decimals to display.
For object iteration we usually use a for..in
loop. This structure will loop through all enumerable properties, including ones who are inherited via prototypal inheritance. For example:
let obj = {_x000D_
prop1: '1',_x000D_
prop2: '2'_x000D_
}_x000D_
_x000D_
for(let el in obj) {_x000D_
console.log(el);_x000D_
console.log(obj[el]);_x000D_
}
_x000D_
However, for..in
will loop over all enumerable elements and this will not able us to split the iteration in chunks. To achieve this we can use the built in Object.keys()
function to retrieve all the keys of an object in an array. We then can split up the iteration into multiple for loops and access the properties using the keys array. For example:
let obj = {_x000D_
prop1: '1',_x000D_
prop2: '2',_x000D_
prop3: '3',_x000D_
prop4: '4',_x000D_
};_x000D_
_x000D_
const keys = Object.keys(obj);_x000D_
console.log(keys);_x000D_
_x000D_
_x000D_
for (let i = 0; i < 2; i++) {_x000D_
console.log(obj[keys[i]]);_x000D_
}_x000D_
_x000D_
_x000D_
for (let i = 2; i < 4; i++) {_x000D_
console.log(obj[keys[i]]);_x000D_
}
_x000D_
Pressing Ctrl + F5 (or Ctrl + Shift + R) to force a cache reload. I believe Macs use Cmd + Shift + R.
In PHP, you can disable the cache by setting the expiration date to a time in the past with headers:
header("Expires: Tue, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
Chrome's cache can be disabled by opening the developer tools with F12, clicking on the gear icon in the lower right corner and selecting Disable cache in the settings dialog, like this:

Type about:config
into the URL bar then find the entry titled network.http.use-cache

From the documentation:
The list is in arbitrary order, and does not include the special entries '.' and '..' even if they are present in the directory.
This means that the order is probably OS/filesystem dependent, has no particularly meaningful order, and is therefore not guaranteed to be anything in particular. As many answers mentioned: if preferred, the retrieved list can be sorted.

These are the installation i had to run in order to make it work on fedora 22 :-

Using System.Text.Json

string json = JsonSerializer.Serialize<Type>(object, options);
By default, on many platforms the short will be aligned to an offset at a multiple of 2, so there will be a padding byte added after the char.
To disable this, use: struct.unpack("=BH", data)
. This will use standard alignment, which doesn't add padding:
>>> struct.calcsize('=BH')
3
The =
character will use native byte ordering. You can also use <
or >
instead of =
to force little-endian or big-endian byte ordering, respectively.
Here's the brute-force approach. It also removes the configuration of the repository.
Note: This does NOT work if the repository has submodules! If you are using submodules, you should use e.g. interactive rebase
Step 1: remove all history (Make sure you have backup, this cannot be reverted)
cat .git/config # note <github-uri>
rm -rf .git
Step 2: reconstruct the Git repo with only the current content
git init
git add .
git commit -m "Initial commit"
Step 3: push to GitHub.
git remote add origin <github-uri>
git push -u --force origin master
Objective C includes a built-in way to detect a the encoding of a string embedded in NSData.
NSData* data = // Assign your NSData object...

Alternatively, you can also parse a standard markdown document (without code blocks per se) on the fly by the markdownreports package.
You can easily determine the file MIME type with JavaScript's FileReader
before uploading it to a server. I agree that we should prefer server-side checking over client-side, but client-side checking is still possible. I'll show you how and provide a working demo at the bottom.
Check that your browser supports both File
and Blob
. All major ones should.
if (window.FileReader && window.Blob) {
// All the File APIs are supported.
} else {
// File and Blob are not supported
}
You can retrieve the File
information from an <input>
element like this (ref):
<input type="file" id="your-files" multiple>
<script>
var control = document.getElementById("your-files");
control.addEventListener("change", function(event) {
// When the control has changed, there are new files
var files = control.files,
for (var i = 0; i < files.length; i++) {
console.log("Filename: " + files[i].name);
console.log("Type: " + files[i].type);
console.log("Size: " + files[i].size + " bytes");
}
}, false);
</script>
Here is a drag-and-drop version of the above (ref):
<div id="your-files"></div>
<script>
var target = document.getElementById("your-files");
target.addEventListener("dragover", function(event) {
event.preventDefault();
}, false);
target.addEventListener("drop", function(event) {
// Cancel default actions
event.preventDefault();
var files = event.dataTransfer.files,
for (var i = 0; i < files.length; i++) {
console.log("Filename: " + files[i].name);
console.log("Type: " + files[i].type);
console.log("Size: " + files[i].size + " bytes");
}
}, false);
</script>
We can now inspect the files and tease out headers and MIME types.
✘ Quick method
You can naïvely ask Blob for the MIME type of whatever file it represents using this pattern:
var blob = files[i]; // See step 1 above
console.log(blob.type);
For images, MIME types come back like the following:
image/jpeg
image/png
...
Caveat: The MIME type is detected from the file extension and can be fooled or spoofed. One can rename a .jpg
to a .png
and the MIME type will be be reported as image/png
.
✓ Proper header-inspecting method
To get the bonafide MIME type of a client-side file we can go a step further and inspect the first few bytes of the given file to compare against so-called magic numbers. Be warned that it's not entirely straightforward because, for instance, JPEG has a few "magic numbers". This is because the format has evolved since 1991. You might get away with checking only the first two bytes, but I prefer checking at least 4 bytes to reduce false positives.
Example file signatures of JPEG (first 4 bytes):
FF D8 FF E0 (SOI + ADD0)
FF D8 FF E1 (SOI + ADD1)
FF D8 FF E2 (SOI + ADD2)
Here is the essential code to retrieve the file header:
var blob = files[i]; // See step 1 above
var fileReader = new FileReader();
fileReader.onloadend = function(e) {
var arr = (new Uint8Array(e.target.result)).subarray(0, 4);
var header = "";
for(var i = 0; i < arr.length; i++) {
header += arr[i].toString(16);
}
console.log(header);
// Check the file signature against known types
};
fileReader.readAsArrayBuffer(blob);
You can then determine the real MIME type like so (more file signatures here and here):
switch (header) {
case "89504e47":
type = "image/png";
break;
case "47494638":
type = "image/gif";
break;
case "ffd8ffe0":
case "ffd8ffe1":
case "ffd8ffe2":
case "ffd8ffe3":
case "ffd8ffe8":
type = "image/jpeg";
break;
default:
type = "unknown"; // Or you can use the blob.type as fallback
break;
}
Accept or reject file uploads as you like based on the MIME types expected.
Here is a working demo for local files and remote files (I had to bypass CORS just for this demo). Open the snippet, run it, and you should see three remote images of different types displayed. At the top you can select a local image or data file, and the file signature and/or MIME type will be displayed.
Notice that even if an image is renamed, its true MIME type can be determined. See below.

XAMPP is an integrated package and you can not downgrade or change one of its component such as php. (There are some solutions that you can use but there is little chances that everything work fine.)
You can download the package from these links:
You had better to download the old package form sourceforge.net.
When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.
With Basic Auth, the HTTP request from the question will look something like this:
GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk
The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password)
.
To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl
, the username and password will be clearly visible on the process list and might turn up in the bash history file.
When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.
Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.
When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.
Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.
There are different clipboards in Linux; the X server has one, the window manager might have another one, etc. There is no standard device.
Oh, yes, on CLI, the screen program has its own clipboard as well, as do some other applications like Emacs and vi.
In X, you can use xclip.

After encountering the same issue in a Web API 2 project (and being unable to use the standard CORS packages for reasons not worth going into here), I was able to resolve this by implementing a custom DelagatingHandler:
public class AllowOptionsHandler : DelegatingHandler
{
protected override async Task<HttpResponseMessage> SendAsync(
HttpRequestMessage request, CancellationToken cancellationToken)
{
var response = await base.SendAsync(request, cancellationToken);
if (request.Method == HttpMethod.Options &&
response.StatusCode == HttpStatusCode.MethodNotAllowed)
{
response = new HttpResponseMessage(HttpStatusCode.OK);
}
return response;
}
}
For the Web API configuration:
config.MessageHandlers.Add(new AllowOptionsHandler());
Note that I also have the CORS headers enabled in Web.config, similar to some of the other answers posted here:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule" />
</modules>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Headers" value="accept, cache-control, content-type, authorization" />
<add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
</customHeaders>
</httpProtocol>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="TRACEVerbHandler" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
Note that my project does not include MVC, only Web API 2.
In XCode 6.3.1, if you use a NSTextField
you will not see the checkbox for secure
.
Instead of using NSTextField
use NSSecureTextField
I'm guessing this is a Swift/Objective-C change since there is now a class for secure text fields. In the above link it says Available in OS X v10.0 and later.
If you know more about when/why/what versions of Swift/Objective-C, XCode, or OS X this
With SSL the encryption is at the transport level, so it takes place before a request is sent.
So everything in the request is encrypted.
Do not overwrite CMAKE_C_COMPILER
, but export CC
(and CXX
) before calling cmake:
export CC=/usr/local/bin/gcc
export CXX=/usr/local/bin/g++
cmake /path/to/your/project
make
The export only needs to be done once, the first time you configure the project, then those values will be read from the CMake cache.
UPDATE: longer explanation on why not overriding CMAKE_C(XX)_COMPILER
after Jake's comment
I recommend against overriding the CMAKE_C(XX)_COMPILER
value for two main reasons: because it won't play well with CMake's cache and because it breaks compiler checks and tooling detection.
When using the set
command, you have three options:
Let's see what happens for the three possible calls to set
:
Without cache
set(CMAKE_C_COMPILER /usr/bin/clang)
set(CMAKE_CXX_COMPILER /usr/bin/clang++)
When doing this, you create a "normal" variable CMAKE_C(XX)_COMPILER
that hides the cache variable of the same name. That means your compiler is now hard-coded in your build script and you cannot give it a custom value. This will be a problem if you have multiple build environments with different compilers. You could just update your script each time you want to use a different compiler, but that removes the value of using CMake in the first place.
Ok, then, let's update the cache...
With cache
set(CMAKE_C_COMPILER /usr/bin/clang CACHE PATH "")
set(CMAKE_CXX_COMPILER /usr/bin/clang++ CACHE PATH "")
This version will just "not work". The CMAKE_C(XX)_COMPILER
variable is already in the cache, so it won't get updated unless you force it.
Ah... let's use the force, then...
Force cache
set(CMAKE_C_COMPILER /usr/bin/clang CACHE PATH "" FORCE)
set(CMAKE_CXX_COMPILER /usr/bin/clang++ CACHE PATH "" FORCE)
This is almost the same as the "normal" variable version, the only difference is your value will be set in the cache, so users can see it. But any change will be overwritten by the set
command.
Breaking compiler checks and tooling
Early in the configuration process, CMake performs checks on the compiler: Does it work? Is it able to produce executables? etc. It also uses the compiler to detect related tools, like ar
and ranlib
. When you override the compiler value in a script, it's "too late", all checks and detections are already done.
For instance, on my machine with gcc as default compiler, when using the set
command to /usr/bin/clang
, ar
is set to /usr/bin/gcc-ar-7
. When using an export before running CMake it is set to /usr/lib/llvm-3.8/bin/llvm-ar
.
With Linq
var ascendingOrder = li.OrderBy(i => i);
var descendingOrder = li.OrderByDescending(i => i);
Without Linq
li.Sort((a, b) => a.CompareTo(b)); // ascending sort
li.Sort((a, b) => b.CompareTo(a)); // descending sort
Note that without Linq, the list itself is being sorted. With Linq, you're getting an ordered enumerable of the list but the list itself hasn't changed. If you want to mutate the list, you would change the Linq methods to something like
li = li.OrderBy(i => i).ToList();
Another way
=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH({"Gingrich","Obama","Romney"},C1)))))>0,"1","")
Also, if you keep a list of values in, say A1 to A3, then you can use
=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH($A$1:$A$3,C1)))))>0,"1","")
The wildcards are not necessary at all in the Search() function, since Search() returns the position of the found string.
You can use the utility method in Collections
class
public static <T extends Comparable<? super T>> void sort(List<T> list)
or
public static <T> void sort(List<T> list,Comparator<? super T> c)
Refer to Comparable
and Comparator
interfaces for more flexibility on sorting the object.
Class2 class2 = new Class2();
Instead of calling the main, perhaps you should call individual methods where and when you need them.
Note: This solution changes based on viewport size and not the amount of content
I just found out that this is possible using VW units. They're the units associated with setting the viewport width. There are some drawbacks, such as lack of legacy browser support, but this is definitely something to seriously consider using. Plus you can still provide fallbacks for older browsers like so:
p {
font-size: 30px;
font-size: 3.5vw;
}

In my case the symbols I create (Tax1, Tax2, etc.) already had values but I wanted to use a loop and assign the symbols to another variable. So the above two answers gave me a way to accomplish this. This may be helpful in answering your question as the assignment of a value can take place anytime later.
output=NULL
for(i in 1:8){
Tax=eval(as.symbol(paste("Tax",i,sep="")))
L_Data1=L_Data_all[which(L_Data_all$Taxon==Tax[1] | L_Data_all$Taxon==Tax[2] | L_Data_all$Taxon==Tax[3] | L_Data_all$Taxon==Tax[4] | L_Data_all$Taxon==Tax[5]),]
L_Data=L_Data1$Length[which(L_Data1$Station==Plant[1] | L_Data1$Station==Plant[2])]
h=hist(L_Data,breaks=breaks,plot=FALSE)
output=cbind(output,h$counts)
}
I hated all these answers because they were too short or relied on other frameworks.

Use below code for sorting in alphabetical order:
NSArray *unsortedStrings = @[@"Verdana", @"MS San Serif", @"Times New Roman",@"Chalkduster",@"Impact"];
NSArray *sortedStrings =

I think you need something like:
var text= data.response.venue.tips.groups[0].items[1].text;
You probably shouldn't, and you can probably do what you want to do in a safer and simpler way. Technically to use variable number of arguments in C you include stdarg.h. From that you'll get the va_list
type as well as three functions that operate on it called va_start()
, va_arg()
and va_end()
.
#include<stdarg.h>
int maxof(int n_args, ...)
{
va_list ap;
va_start(ap, n_args);
int max = va_arg(ap, int);
for(int i = 2; i <= n_args; i++) {
int a = va_arg(ap, int);
if(a > max) max = a;
}
va_end(ap);
return max;
}
If you ask me, this is a mess. It looks bad, it's unsafe, and it's full of technical details that have nothing to do with what you're conceptually trying to achieve. Instead, consider using overloading or inheritance/polymorphism, builder pattern (as in operator<<()
in streams) or default arguments etc. These are all safer: the compiler gets to know more about what you're trying to do so there are more occasions it can stop you before you blow your leg off.
I prefer to use the ngModel and ngChange directives when dealing with checkboxes. ngModel allows you to bind the checked/unchecked state of the checkbox to a property on the entity:
<input type="checkbox" ng-model="entity.isChecked">
Whenever the user checks or unchecks the checkbox the entity.isChecked
value will change too.
If this is all you need then you don't even need the ngClick or ngChange directives. Since you have the "Check All" checkbox, you obviously need to do more than just set the value of the property when someone checks a checkbox.
When using ngModel with a checkbox, it's best to use ngChange rather than ngClick for handling checked and unchecked events. ngChange is made for just this kind of scenario. It makes use of the ngModelController for data-binding (it adds a listener to the ngModelController's $viewChangeListeners
array. The listeners in this array get called after the model value has been set, avoiding this problem).
<input type="checkbox" ng-model="entity.isChecked" ng-change="selectEntity()">
... and in the controller ...
var model = {};
$scope.model = model;
// This property is bound to the checkbox in the table header
model.allItemsSelected = false;
// Fired when an entity in the table is checked
$scope.selectEntity = function () {
// If any entity is not checked, then uncheck the "allItemsSelected" checkbox
for (var i = 0; i < model.entities.length; i++) {
if (!model.entities[i].isChecked) {
model.allItemsSelected = false;
return;
}
}
// ... otherwise ensure that the "allItemsSelected" checkbox is checked
model.allItemsSelected = true;
};
Similarly, the "Check All" checkbox in the header:
<th>
<input type="checkbox" ng-model="model.allItemsSelected" ng-change="selectAll()">
</th>
... and ...
// Fired when the checkbox in the table header is checked
$scope.selectAll = function () {
// Loop through all the entities and set their isChecked property
for (var i = 0; i < model.entities.length; i++) {
model.entities[i].isChecked = model.allItemsSelected;
}
};
CSS
What is the best way to... add a CSS class to the
<tr>
containing the entity to reflect its selected state?
If you use the ngModel approach for the data-binding, all you need to do is add the ngClass directive to the <tr>
element to dynamically add or remove the class whenever the entity property changes:
<tr ng-repeat="entity in model.entities" ng-class="{selected: entity.isChecked}">
See the full Plunker here.
declare n number(10);
begin
select count(*) into n from tab where tname='TEST';
if (n = 0) then
execute immediate
'create table TEST ( ID NUMBER(3), NAME VARCHAR2 (30) NOT NULL)';
end if;
end;
For debugging purposes, you can use the DLL file. You can run it using dotnet ConsoleApp2.dll
. If you want to generate an EXE file, you have to generate a self-contained application.
To generate a self-contained application (EXE in Windows), you must specify the target runtime (which is specific to the operating system you target).
Pre-.NET Core 2.0 only: First, add the runtime identifier of the target runtimes in the .csproj file (list of supported RIDs):
<PropertyGroup>
<RuntimeIdentifiers>win10-x64;ubuntu.16.10-x64</RuntimeIdentifiers>
</PropertyGroup>
The above step is no longer required starting with .NET Core 2.0.
Then, set the desired runtime when you publish your application:
dotnet publish -c Release -r win10-x64
dotnet publish -c Release -r ubuntu.16.10-x64

There are a lot of great articles on how to manipulate objects in Javascript (whether using Node JS or a browser). I suggest here is a good place to start: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Working_with_Objects
2014 March: Truncating long strings with CSS: a new answer with focus on browser support
Demo on http://jsbin.com/leyukama/1/ (I use jsbin because it supports old version of IE).
<style type="text/css">
span {
display: inline-block;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis; /** IE6+, Firefox 7+, Opera 11+, Chrome, Safari **/
-o-text-overflow: ellipsis; /** Opera 9 & 10 **/
width: 370px; /* note that this width will have to be smaller to see the effect */
}
</style>
<span>Some very long text that should be cut off at some point coz it's a bit too long and the text overflow ellipsis feature is used</span>
The -ms-text-overflow CSS property is not necessary: it is a synonym of the text-overflow CSS property, but versions of IE from 6 to 11 already support the text-overflow CSS property.
Successfully tested (on Browserstack.com) on Windows OS, for web browsers:
Firefox: as pointed out by Simon Lieschke (in another answer), Firefox only support the text-overflow CSS property from Firefox 7 onwards (released September 27th 2011).
I double checked this behavior on Firefox 3.0 & Firefox 6.0 (text-overflow is not supported).
Some further testing on a Mac OS web browsers would be needed.
Note: you may want to show a tooltip on mouse hover when an ellipsis is applied, this can be done via javascript, see this questions: HTML text-overflow ellipsis detection and HTML - how can I show tooltip ONLY when ellipsis is activated

The easiest way to do this is with remove_all function of the Boost.Filesystem library. Besides, the resulting code will be portable.
If you want to write something specific for Unix (rmdir) or for Windows (RemoveDirectory) then you'll have to write a function that deletes are subfiles and subfolders recursively.
EDIT
Looks like this question was already asked, in fact someone already recommended Boost's remove_all. So please don't upvote my answer.
If you have the stats toolbox, then you can compute
Z = zscore(S);
NSArray *myArray = [NSArray arrayWithObjects:[NSNumber numberWithInt:1], [NSNumber numberWithInt:2], [NSNumber numberWithInt:3]];
Update for new Objective-C syntax:
NSArray *myArray = @[@1, @2, @3];
Those two declarations are identical from the compiler's perspective.
if you're just wanting to use an integer in a string for putting into a textbox or something:
int myInteger = 5;
NSString* myNewString = [NSString stringWithFormat:@"%i", myInteger];
Use control+option+L to auto import the package and auto remove unused packages on Mac
The upvoted solution works for some situations but is not the ideal solution. The solution Bhojendra Rauniyar provided will only work in certain scenarios. The var inputVal will always remain the same, so changing the input multiple times would break the function.
The function may also break when using focus, because of the ?? (up/down) spinner on html number input. That is why J.T. Taylor has the best solution. By adding a data attribute you can avoid these problems:
<input id="my-textbox" type="text" data-initial-value="6" value="6" />
Use theme()
:
d <- data.frame(x=gl(10, 1, 10, labels=paste("long text label ", letters[1:10])), y=rnorm(10))
ggplot(d, aes(x=x, y=y)) + geom_point() +
theme(text = element_text(size=20),
axis.text.x = element_text(angle=90, hjust=1))
#vjust adjust the vertical justification of the labels, which is often useful
There's lots of good information about how to format your ggplots here. You can see a full list of parameters you can modify (basically, all of them) using ?theme
.
Why do you want to do that?
However, You can do this:
public void foo(int param1)
{
int param2 = 2;
// rest of code
}
or:
public void foo(int param1, int param2)
{
// rest of code
}
public void foo(int param1)
{
foo(param1, 2);
}
You can't create a 'const' array because arrays are objects and can only be created at runtime and const entities are resolved at compile time.
What you can do instead is to declare your array as "readonly". This has the same effect as const except the value can be set at runtime. It can only be set once and it is thereafter a readonly (i.e. const) value.
This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.
In standard SQL one would write:
SELECT t0.foo, t1.bar
FROM FIRST_TABLE t0
RIGHT OUTER JOIN SECOND_TABLE t1;
Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :
Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]
here is a version that handles multiple requests, also checks for cancelled status in callback to suppress errors in error block. (in Typescript)
controller level:
requests = new Map<string, ng.IDeferred<{}>>();
in my http get:
getSomething(): void {
let url = '/api/someaction';
this.cancel(url); // cancel if this url is in progress
var req = this.$q.defer();
this.requests.set(url, req);
let config: ng.IRequestShortcutConfig = {
params: { id: someId}
, timeout: req.promise // <--- promise to trigger cancellation
};
this.$http.post(url, this.getPayload(), config).then(
promiseValue => this.updateEditor(promiseValue.data as IEditor),
reason => {
// if legitimate exception, show error in UI
if (!this.isCancelled(req)) {
this.showError(url, reason)
}
},
).finally(() => { });
}
helper methods
cancel(url: string) {
this.requests.forEach((req,key) => {
if (key == url)
req.resolve('cancelled');
});
this.requests.delete(url);
}
isCancelled(req: ng.IDeferred<{}>) {
var p = req.promise as any; // as any because typings are missing $$state
return p.$$state && p.$$state.value == 'cancelled';
}
now looking at the network tab, i see that it works beatuifully. i called the method 4 times and only the last one went through.
I've had this happen before as well, where there was TeamViewer client takes the control of the TAB key. You won't know this until you close the TV window that you have open in the background.
