As workaround you could use formaction
attribute on submit button. And just use different names on your inputs.
<form action="a">
<input.../>
<!-- Form 2 inputs -->
<input.../>
<input.../>
<input.../>
<input type="submit" formaction="b">
</form>
<input.../>
My understanding has always been:
ID's are single use and are only applied to one element...
Classes can be used more than once...
It's
#include <stdio.h>
int main(void) {
int x = 10;
while (x-- > 0) { // x goes to 0
printf("%d ", x);
}
return 0;
}
Just the space makes the things look funny, --
decrements and >
compares.
To validate base64 image we can use this regex
/^data:image/(?:gif|png|jpeg|bmp|webp)(?:;charset=utf-8)?;base64,(?:[A-Za-z0-9]|[+/])+={0,2}
private validBase64Image(base64Image: string): boolean {
const regex = /^data:image\/(?:gif|png|jpeg|bmp|webp)(?:;charset=utf-8)?;base64,(?:[A-Za-z0-9]|[+/])+={0,2}/;
return base64Image && regex.test(base64Image);
}
Just to expand on this error in the context of an interface, if you are type hinting your function parameters like so:
interface A
use Bar;
interface A
{
public function foo(Bar $b);
}
Class B
class B implements A
{
public function foo(Bar $b);
}
If you have forgotten to include the use
statement on your implementing class (Class B), then you will also get this error even though the method parameters are identical.
First off you can't have just a number for your id unless you are using the HTML5 DOCTYPE. Secondly, you need to either remove the # in each id or replace it with this:
$container.cycle(id.replace('#',''));
If using laradock, try chown -R laradock:www-data ./storage
in your workspace container
In a bourne shell:
make > my.log 2>&1
I.e. > redirects stdout, 2>&1 redirects stderr to the same place as stdout
I had a similar issue. In eclipse I compared my project with a sample project which is working fine (generated by a maven archetype). I found my project has missed 2 lines in /.classpath file. I copied those 2 lines and it fixed the issue. It seems even though I set build path in project preferences, eclipse has not updated accordingly for some reasons.
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" output="target/classes" path="src/main/java"/>
<classpathentry kind="src" output="target/test-classes" path="src/test/java"/>
...
</classpath>
I've had a similar problem for the last few days. For me the cause was a combination of systemd, docker and my hosting provider. I'm running up-to-date CentOS (7.7.1908).
My hosting provider automatically generates a config file for systemd-networkd. Starting with systemd 219 which is the current version for CentOS 7, systemd-networkd took control of network-related sysctl parameters. Docker seems to be incompatible with this version and will reset the IP-Forwarding flags everytime a container is launched.
My solution was to add IPForward=true
in the [Network]
-section of my provider-generated config file. This file might be in several places, most likely in /etc/systemd/network
.
The process is also described in the official docker docs: https://docs.docker.com/v17.09/engine/installation/linux/linux-postinstall/#ip-forwarding-problems
Or simply Use union, for simple array.
_.union([1,2,3,3], [3,5])
// [1,2,3,5]
If you're copying data like that, that probably means your datamodel isn't fully normalized, right? Is it possible to make one list of countries and do a JOIN more?
Instead of a JOIN you could also use virtual tables so you don't have to change the queries in your system.
If you are storing keys/values as strings, then this will work:
HashMap<String, String> newMap = new HashMap<String, String>();
newMap.put("my_code", "shhh_secret");
String value = newMap.get("my_code");
The question is what gets populated in the HashMap (key & value)
type NumberArray = Array<{id: number, text: string}>;
const arr: NumberArray = [
{id: 0, text: 'Number 0'},
{id: 1, text: 'Number 1'},

{id: 3, text: 'Number 3 '},
{id: 4, text: 'Number 4 '},
{id: 5, text: 'Number 5 '},
];
I encountered this error while executing
SELECT * FROM table;
I traced the error to cursor.py line 195.
if args is not None:
if isinstance(args, dict):

Given that I am entering any extra parameters, I got rid of all of "if args ..." branch. Now it works.
Probably it would be easier and neater to close the file after text = re.sub('foobar', 'bar', text)
, re-open it for writing (thus clearing old contents), and write your updated text to it.
As a tangential note, one case where the ability to have multiple .gitignore
files is very useful is if you want an extra directory in your working copy that you never intend to commit. Just put a 1-byte .gitignore
(containing just a single asterisk) in that directory and it will never show up in git status
etc.
package main
import "fmt"
import "strconv"
func FloatToString(input_num float64) string {
// to convert a float number to a string
return strconv.FormatFloat(input_num, 'f', 6, 64)
}
func main() {
fmt.Println(FloatToString(21312421.213123))
}
If you just want as many digits precision as possible, then the special precision -1 uses the smallest number of digits necessary such that ParseFloat will return f exactly. Eg
strconv.FormatFloat(input_num, 'f', -1, 64)
Personally I find fmt
easier to use. (Playground link)
fmt.Printf("x = %.6f\n", 21312421.213123)
Or if you just want to convert the string
fmt.Sprintf("%.6f", 21312421.213123)
I was facing the same problem. It works for me. Please check this.
json_encode($array,JSON_UNESCAPED_UNICODE);
Connection refused means that the port you are trying to connect to is not actually open.
So either you are connecting to the wrong IP address, or to the wrong port, or the server is listening on the wrong port, or is not actually running.
A common mistake is not specifying the port number when binding or connecting in network byte order...
The problem is that the timer
variable is local, and its value is lost after each function call.
You need to persist it, you can put it outside the function, or if you don't want to expose the variable as global, you can store it in a closure, e.g.:
var endAndStartTimer = (function () {
var timer; // variable persisted here
return function () {
window.clearTimeout(timer);
//var millisecBeforeRedirect = 10000;
timer = window.setTimeout(function(){alert('Hello!');},10000);
};
})();
The typed way to do this would be:
Number(true) // 1
Number(false) // 0
Updated answer that will solve your problem and also just a general good how-to for installing Oracle Java 7 on Ubuntu can be found here: http://www.wikihow.com/Install-Oracle-Java-on-Ubuntu-Linux
If you want to accept lower-ascii digits only, here are tests to do so:
Python 3.7+: (u.isdecimal() and u.isascii())
Python <= 3.6: (u.isdecimal() and u == str(int(u)))
Other answers suggest using .isdigit()
or .isdecimal()
but these both include some upper-unicode characters such as '?'
(u'\u0662'
):
u = u'\u0662' # '?'
u.isdigit() # True
u.isdecimal() # True
u.isascii() # False (Python 3.7+ only)
u == str(int(u)) # False

First get the value from edit text in a String variable
String value = edttxt.getText().toString();
Then set that value to textView
txtview.setText(value);
Where edttxt refers to edit text field in XML file and txtview refers to textfield in XML file to show the value
Int
32 bits (4byte)
-2,147,483,648 to 2,147,483,647
Long
64 bits (8byte)
-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
If your usage of a variable falls in the 32 bit range, use Int
, else use long
. Usually long is used for scientific computations and stuff like that need much accuracy. (eg. value of pi).
An example of choosing one over the other is YouTube's case. They first defined video view counter as an
int
which was overflowed when more than 2,147,483,647 views where received to a popular video. Since anInt
counter cannot store any value more than than its range, YouTube changed the counter to a 64 bit variable and now can count up to 9,223,372,036,854,775,807 views. Understand your data and choose the type which fits as 64 bit variable will take double the memory than a 32 bit variable.
But while mocking read-only properties means properties with getter method only you should declare it as virtual otherwise System.NotSupportedException will be thrown because it is only supported in VB as moq internally override and create proxy when we mock anything.
The Helvetica font does not come included with Windows, so to use it you must download it as a .ttf file. Then you can refer matplotlib to it like this (replace "crm10.ttf" with your file):
import os
from matplotlib import font_manager as fm, rcParams
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
fpath = os.path.join(rcParams["datapath"], "fonts/ttf/cmr10.ttf")
prop = fm.FontProperties(fname=fpath)
fname = os.path.split(fpath)[1]
ax.set_title('This is a special font: {}'.format(fname), fontproperties=prop)
ax.set_xlabel('This is the default font')
plt.show()
print(fpath)
will show you where you should put the .ttf.
You can see the output here: https://matplotlib.org/gallery/api/font_file.html
If you create a new database it's good to create user with permissions only for this database (if anything goes wrong you won't compromise root user login and password). So everything together will look like this:
mysql -u base_user -pbase_user_pass -e "create database new_db; GRANT ALL PRIVILEGES ON new_db.* TO new_db_user@localhost IDENTIFIED BY 'new_db_user_pass'"
Where:
base_user is the name for user with all privileges (probably the root)
base_user_pass it's the password for base_user (lack of space between -p and base_user_pass is important)
new_db is name for newly created database
new_db_user is name for the new user with access only for new_db
new_db_user_pass it's the password for new_db_user
I want to change the width and height of a div. data attributes did not change it. Instead I use:
var size = $("#theme_photo_size").val().split("x");
$("#imageupload_img").width(size[0]);
$("#imageupload_img").attr("data-width", size[0]);
$("#imageupload_img").height(size[1]);
$("#imageupload_img").attr("data-height", size[1]);
be careful:
$("#imageupload_img").data("height", size[1]); //did not work
did not set it
$("#imageupload_img").attr("data-height", size[1]); // yes it worked!
this has set it.
This is a syntax issue, the jQuery library included with WordPress loads in "no conflict" mode. This is to prevent compatibility problems with other javascript libraries that WordPress can load. In "no-confict" mode, the $ shortcut is not available and the longer jQuery is used, i.e.
jQuery(document).ready(function ($) {
By including the $ in parenthesis after the function call you can then use this shortcut within the code block.
For full details see WordPress Codex
You can get a passphrase out of an arbitrary password by using a cryptographic hash function (NOT Python's builtin hash
) like SHA-1 or SHA-256. Python includes support for both in its standard library:
import hashlib
hashlib.sha1("this is my awesome password").digest() # => a 20 byte string
hashlib.sha256("another awesome password").digest() # => a 32 byte string
You can truncate a cryptographic hash value just by using [:16]
or [:24]
and it will retain its security up to the length you specify.
It's been commented multiple times that this is not the correct answer to this question, and I agree. Back when this answer was written, IE 9 was still new (about 8 months old) and many developers including myself needed a solution for <= IE 9. IE 9 is when IE started supporting background-origin
. However, it's been over six and a half years, so here's the updated solution which I highly recommend over using an actual border. In case < IE 9 support is needed. My original answer can be found below the demo snippet. It uses an opaque border to simulate padding for background images.
#hello {
padding-right: 10px;
background-color:green;
background: url("https://placehold.it/15/5C5/FFF") no-repeat scroll right center #e8e8e8;
background-origin: content-box;
}
_x000D_
<p id="hello">I want the background icon to have padding to it too!I want the background icon twant the background icon to have padding to it too!I want the background icon to have padding to it too!I want the background icon to have padding to it too!</p>
_x000D_
you can fake it with a 10px border of the same color as the background:
http://jsbin.com/eparad/edit#javascript,html,live
#hello {
border: 10px solid #e8e8e8;
background-color: green;
background: url("http://www.costascuisine.com/images/buttons/collapseIcon.gif")
no-repeat scroll right center #e8e8e8;
}
I'd start by using glob:
from PIL import Image
import glob
image_list = []
for filename in glob.glob('yourpath/*.gif'): #assuming gif
im=Image.open(filename)
image_list.append(im)
then do what you need to do with your list of images (image_list).
Add at the top:
SET DATEFORMAT ymd;
or whichever format you are using in your queries

Theres a difference in <<-TEXT
and <<~TEXT
, former retains the spacing inside block and latter doesn't.
There are other options as well. Like concatenation etc. but this one makes more sense in general.
If I am wrong here, let me know how...
There is an important difference between std::min
, std::max
and fmin
and fmax
.
std::min(-0.0,0.0) = -0.0
std::max(-0.0,0.0) = -0.0
whereas
fmin(-0.0, 0.0) = -0.0
fmax(-0.0, 0.0) = 0.0
So std::min
is not a 1-1 substitute for fmin
. The functions std::min
and std::max
are not commutative. To get the same result with doubles with fmin
and fmax
one should swap the arguments
fmin(-0.0, 0.0) = std::min(-0.0, 0.0)
fmax(-0.0, 0.0) = std::max( 0.0, -0.0)
But as far as I can tell all these functions are implementation defined anyway in this case so to be 100% sure you have to test how they are implemented.
There is another important difference. For x ! = NaN
:
std::max(Nan,x) = NaN
std::max(x,NaN) = x
std::min(Nan,x) = NaN
std::min(x,NaN) = x
whereas
fmax(Nan,x) = x
fmax(x,NaN) = x
fmin(Nan,x) = x
fmin(x,NaN) = x
fmax
can be emulated with the following code
double myfmax(double x, double y)
{
// z > nan for z != nan is required by C the standard
int xnan = isnan(x), ynan = isnan(y);
if(xnan || ynan) {
if(xnan && !ynan) return y;
if(!xnan && ynan) return x;
return x;
}
// +0 > -0 is preferred by C the standard
if(x==0 && y==0) {
int xs = signbit(x), ys = signbit(y);
if(xs && !ys) return y;
if(!xs && ys) return x;
return x;
}
return std::max(x,y);
}
This shows that std::max
is a subset of fmax
.
Looking at the assembly shows that Clang uses builtin code for fmax
and fmin
whereas GCC calls them from a math library. The assembly for clang for fmax
with -O3
is
movapd xmm2, xmm0
cmpunordsd xmm2, xmm2
movapd xmm3, xmm2
andpd xmm3, xmm1
maxsd xmm1, xmm0
andnpd xmm2, xmm1
orpd xmm2, xmm3
movapd xmm0, xmm2
whereas for std::max(double, double)
it is simply
maxsd xmm0, xmm1
However, for GCC and Clang using -Ofast
fmax
becomes simply
maxsd xmm0, xmm1
So this shows once again that std::max
is a subset of fmax
and that when you use a looser floating point model which does not have nan
or signed zero then fmax
and std::max
are the same. The same argument obviously applies to fmin
and std::min
.
Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.
Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .
if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .
if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .
after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).
if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.
If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.
If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.
If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.
if you further face any difficulty then you need to provide more information about your web site and sql server .
In general, an alternative to case when ...
is coalesce(nullif(x,bad_value),y)
(that cannot be used in OP's case). For example,
select coalesce(nullif(y,''),x), coalesce(nullif(x,''),y), *
from ( (select 'abc' as x, '' as y)
union all (select 'def' as x, 'ghi' as y)
union all (select '' as x, 'jkl' as y)
union all (select null as x, 'mno' as y)
union all (select 'pqr' as x, null as y)
) q
gives:
coalesce | coalesce | x | y
----------+----------+-----+-----
abc | abc | abc |
ghi | def | def | ghi
jkl | jkl | | jkl
mno | mno | | mno
pqr | pqr | pqr |

If you want to run the tsc command from the integrated terminal with the TypeScript module installed locally, you can add the following to your .vscode\settings.json file.
{
"terminal.integrated.env.windows": { "PATH": "${workspaceFolder}\\node_modules\\.bin;${env:PATH}" }
}
This will prepend the locally installed node module's binary/executable directory (where tsc.cmd is located) to the $env.PATH variable.
if you're hosting behind a server, and still facing issues: try changing localhost to 127.0.0.1 e.g. http://localhost:8080/ to http://127.0.0.1:8080/
The issue I was facing was that I was serving a site using apache tomcat within an eclipse IDE (eclipse luna).
For my sanity check I was using Remy Sharp's demo: https://github.com/remy/html5demos/blob/eae156ca2e35efbc648c381222fac20d821df494/demos/geo.html
and was getting the error after making minor tweaks to the error function despite hosting the code on the server (was only working on firefox and failing on chrome and safari):
"User denied Geolocation"
I made the following change to get more detailed error message:
function error(msg) {
var s = document.querySelector('#status');
msg = msg.message ? msg.message : msg; //add this line
s.innerHTML = typeof msg == 'string' ? msg : "failed";
s.className = 'fail';
// console.log(arguments);
}

Instead of setting drawable resource through code in your activity class you can also set in XML layout:
Code is as follows:
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/apple" />
The latest Spring + JPA versions solve this problem fundamentally. You can learn more how to use Spring and JPA togather in a separate thread
I found this works:
window = Tk()
window.title('Window')
Maybe this helps?
I would use regular expression matching to sum over variables with certain pattern names. For example:
df <- df %>% mutate(sum1 = rowSums(.[grep("x[3-5]", names(.))], na.rm = TRUE),
sum_all = rowSums(.[grep("x", names(.))], na.rm = TRUE))
This way you can create more than one variable as a sum of certain group of variables of your data frame.
foreach (var item in dicNumber)
{
listnumber.Add(item.Key);
}
Here is what I do for any action and it works in Firefox, IE, Opera, and Safari.
<script type="text/javascript">
$(document).ready(function(){

... do what ever ...
}
function doMethod()
{
var iFrames = document.getElementsByTagName('iframe');
// what ever action you want.
function iAction()
{
// Iterate through all iframes in the page.
for (var i = 0, j = iFrames.length; i < j; i++)
{
actionIframe(iFrames[i]);
}
}
// Check if browser is Safari or Opera.
if ($.browser.safari || $.browser.opera)
{
// Start timer when loaded.
$('iframe').load(function()
{
setTimeout(iAction, 0);
}
);
// Safari and Opera need something to force a load.
for (var i = 0, j = iFrames.length; i < j; i++)
{
var iSource = iFrames[i].src;
iFrames[i].src = '';
iFrames[i].src = iSource;
}
}
else
{
// For other good browsers.
$('iframe').load(function()
{
actionIframe(this);
}
);
}
}
</script>
Use a Page Viewer webpart and switch from Web Page to Folder. You can the specify the folder you want to display in the Link.
It turns out the answer was ridiculously simple, but mystifying as to why it was necessary.
In the IIS Manager on the server, I set the application pool for my web application to not allow 32-bit assemblies.
It seems it assumes, on a 64-bit system, that you must want the 32 bit assembly. Bizarre.
If you want to DUMP your inserts into an .sql file:
cd
to the location which you want to .sql
file to be locatedpg_dump --column-inserts --data-only --table=<table> <database> > my_dump.sql
Note the > my_dump.sql
command. This will put everything into a sql file named my_dump
json.loads()
takes a JSON encoded string, not a filename. You want to use json.load()
(no s
) instead and pass in an open file object:
with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
data = json.load(jsonfile)
The open()
command produces a file object that json.load()
can then read from, to produce the decoded Python object for you. The with
statement ensures that the file is closed again when done.
The alternative is to read the data yourself and then pass it into json.loads()
.
str = "aaaaabbbb"
newstr = str[-4:]
Just move it to /usr/local/bin

Here is the answer of my question. I've asked that again with some remarks. How to add support libraries?
For Microsoft IIS servers, you can enable this header via your web.config
file:
<system.webServer>
<httpProtocol>
<customHeaders>
<remove name="X-Content-Type-Options"/>
<add name="X-Content-Type-Options" value="nosniff"/>
</customHeaders>
</httpProtocol>
</system.webServer>
And you are done.
This will list all certificates:

Unless you write your own Homescreen launcher or use an existing one from Goolge Play, there's "no way" to resize icons.
Well, "no way" does not mean its impossible:
I do have the same issue, and I am not sure whether it is possible or not,
tried the above solutions are not worked for me.
for a workaround, I am going with moving the files to my HOME directory, editing and replacing the files with SSH.
From what I understand of the scikit-image docs (http://scikit-image.org/docs/dev/index.html), imshow() takes a ndarray as an argument, and not a dictionary:
http://scikit-image.org/docs/dev/api/skimage.io.html?highlight=imshow#skimage.io.imshow
Maybe if you post the whole stack trace, we could see that the TypeError comes somewhere deep from imshow().
Familiar with multilevel hierarchy?
You can use subclass as superclass to your another class.
You can try this.
public class PreferenceActivity extends AbstractBillingActivity {}
then
public class Preferences extends PreferenceActivity {}
In this case, Preferences class inherits both PreferencesActivity and AbstractBillingActivity as well.
If you're running Windows 8/Windows Server 2012 or newer, you can use the Test-NetConnection command in PowerShell.
Ex:
Test-NetConnection -Port 53 -ComputerName LON-DC1
From http://docs.python.org/library/csv.html#csv.writer:
If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.
In other words, when opening the file you pass 'wb' as opposed to 'w'.
You can also use a with
statement to close the file when you're done writing to it.
Tested example below:
from __future__ import with_statement # not necessary in newer versions
import csv
headers=['id', 'year', 'activity', 'lineitem', 'datum']

first of all Port 80(or what ever you are using) and 443 must be allow for both TCP and UDP packets. To do this, create 2 inbound rules for TPC and UDP on Windows Firewall for port 80 and 443. (or you can disable your whole firewall for testing but permanent solution if allow inbound rule)
2.
You need to change the security setting on Apache to allow access from anywhere else, so edit your httpd.conf
file.
Change this section from :
# onlineoffline tag - don't remove
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from ::1
Allow from localhost
To :
# onlineoffline tag - don't remove
Order Allow,Deny
Allow from all
if "Allow from all" line not work for your then use "Require all granted" then it will work for you.
In version 3 and > of WAMPServer there is a Virtual Hosts pre defined for localhost
so dont amend the httpd.conf
file at all, leave it as you found it.
Using the menus, edit the httpd-vhosts.conf
file.
It should look like this :
<VirtualHost *:80>
ServerName localhost
DocumentRoot D:/wamp/www
<Directory "D:/wamp/www/">
Options +Indexes +FollowSymLinks +MultiViews
AllowOverride All
Require local
</Directory>
</VirtualHost>
Amend it to
<VirtualHost *:80>
ServerName localhost
DocumentRoot D:/wamp/www
<Directory "D:/wamp/www/">
Options +Indexes +FollowSymLinks +MultiViews
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
Note:if you are running wamp for other than port 80 then VirtualHost will be like VirtualHost *:86.(86 or port whatever you are using) instead of VirtualHost *:80
3. Dont forget to restart All Services of Wamp or Apache after making this change
I needed a way to do this in an AJAX return, so I wrote this piece:
<p id="num_results">Number of results: <span></span></p>
<div id="results"></div>
<script type="text/javascript">
$(function(){
ajax();
})
//Function that makes Ajax call out to receive search results
var ajax = function() {
//Setup Ajax
$.ajax({
url: '/path/to/url', //URL to load
type: 'GET', //Type of Ajax call
dataType: 'html', //Type of data to be expected on return
success: function(data) { //Function that manipulates the returned AJAX'ed data
$('#results').html(data); //Load the data into a HTML holder
var $el = $('#results'); //jQuery Object that is holding the results
setTimeout(function(){ //Custom callback function to count the number of results
callBack($el);
});
}
});
}
//Custom Callback function to return the number of results
var callBack = function(el) {
var length = $('tr', $(el)).not('tr:first').length; //Count all TR DOM elements, except the first row (which contains the header information)
$('#num_results span').text(length); //Write the counted results to the DOM
}
</script>
Obviously this is a quick example, but it may be helpful.
You could use bind
method
for (var i = 1, j = 1; i <= 3; i++, j++) {
setTimeout(function() {
alert(this);
}.bind(i), j * 100);
}
You start new activities with intents. One method to send data to an intent is to pass a class that implements parcelable in the intent. Take note you are passing a copy of the class.
http://developer.android.com/reference/android/os/Parcelable.html
Here I have an onItemClick. I create intent and putExtra an entire class into the intent. The class I'm sending has implemented parcelable. Tip: You only need implement the parseable over what is minimally needed to re-create the class. Ie maybe a filename or something simple like a string something that a constructor can use to create the class. The new activity can later getExtras and it is essentially creating a copy of the class with its constructor method.
Here I launch the kmlreader class of my app when I recieve an onclick in the listview.
Note: below summary is a list of the class that I am passing so get(position) returns the class infact it is the same list that populates the listview
List<KmlSummary> summary = null;
...
public final static String EXTRA_KMLSUMMARY = "com.gosylvester.bestrides.util.KmlSummary";
...
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
lastshownitem = position;
Intent intent = new Intent(context, KmlReader.class);
intent.putExtra(ImageTextListViewActivity.EXTRA_KMLSUMMARY,
summary.get(position));
startActivity(intent);
}
later in the new activity I pull out the parseable class with
kmlSummary = intent.getExtras().getParcelable(
ImageTextListViewActivity.EXTRA_KMLSUMMARY);
//note:
//KmlSummary implements parcelable.
//there is a constructor method for parcel in
// and a overridden writetoparcel method
// these are really easy to setup.
public KmlSummary(Parcel in) {
this._id = in.readInt();
this._description = in.readString();
this._name = in.readString();
this.set_bounds(in.readDouble(), in.readDouble(), in.readDouble(),
in.readDouble());
this._resrawid = in.readInt();
this._resdrawableid = in.readInt();
this._pathstring = in.readString();
String s = in.readString();
this.set_isThumbCreated(Boolean.parseBoolean(s));
}
@Override
public void writeToParcel(Parcel arg0, int arg1) {
arg0.writeInt(this._id);
arg0.writeString(this._description);
arg0.writeString(this._name);
arg0.writeDouble(this.get_bounds().southwest.latitude);
arg0.writeDouble(this.get_bounds().southwest.longitude);
arg0.writeDouble(this.get_bounds().northeast.latitude);
arg0.writeDouble(this.get_bounds().northeast.longitude);
arg0.writeInt(this._resrawid);
arg0.writeInt(this._resdrawableid);
arg0.writeString(this.get_pathstring());
String s = Boolean.toString(this.isThumbCreated());
arg0.writeString(s);
}

In MySQL a special column function GROUP_CONCAT
can be used:
SELECT GROUP_CONCAT(COLUMN_NAME)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = 'computers' AND
TABLE_NAME='Laptop' AND
COLUMN_NAME NOT IN ('code')
ORDER BY ORDINAL_POSITION;
It should be mentioned that the information schema in MySQL covers all database server, not certain databases. That is why if different databases contains tables with identical names, search
condition of the WHERE
clause should specify the schema name: TABLE_SCHEMA='computers'
.
Strings are concatenated with the CONCAT
function in MySQL. The final solution of our problem can be expressed in MySQL as:
SELECT CONCAT('SELECT ',
(SELECT GROUP_CONCAT(COLUMN_NAME)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA='computers' AND
TABLE_NAME='Laptop' AND
COLUMN_NAME NOT IN ('code')
ORDER BY ORDINAL_POSITION
), ' FROM Laptop');

You can use ng-repeat
with option
like this:
<form>
<select ng-model="yourSelect"
ng-options="option as option for option in ['var1', 'var2', 'var3']"
ng-init="yourSelect='var1'"></select>
<input type="hidden" name="yourSelect" value="{{yourSelect}}" />
</form>
When you submit your form
you can get value of input hidden.
It's much simpler than all that:
while(str.Contains(" ")) str = str.Replace(" ", " ");
For the sake of others who come on this issue, I had this same problem in Ubuntu (namely that my passwords weren't caching, despite having set the option correctly, and getting the error git: 'credential-cache' is not a git command.
), until I found out that this feature is only available in Git 1.7.9 and above.
Being on an older distribution of Ubuntu (Natty; I'm a stubborn Gnome 2 user) the version in the repo was git version 1.7.4.1. I used the following PPA to upgrade: https://launchpad.net/~git-core/+archive/ppa
try
System.Diagnostics.EventLog appLog = new System.Diagnostics.EventLog();
appLog.Source = "This Application's Name";
appLog.WriteEntry("An entry to the Application event log.");
Well I'm sure that this is the simplest way to populate JTable from ResultSet, without any external library. I have included comments in this method.
public void resultSetToTableModel(ResultSet rs, JTable table) throws SQLException{
//Create new table model
DefaultTableModel tableModel = new DefaultTableModel();
//Retrieve meta data from ResultSet
ResultSetMetaData metaData = rs.getMetaData();
//Get number of columns from meta data
int columnCount = metaData.getColumnCount();
//Get all column names from meta data and add columns to table model
for (int columnIndex = 1; columnIndex <= columnCount; columnIndex++){
tableModel.addColumn(metaData.getColumnLabel(columnIndex));
}
//Create array of Objects with size of column count from meta data
Object[] row = new Object[columnCount];
//Scroll through result set
while (rs.next()){
//Get object from column with specific index of result set to array of objects
for (int i = 0; i < columnCount; i++){
row[i] = rs.getObject(i+1);
}
//Now add row to table model with that array of objects as an argument
tableModel.addRow(row);
}
//Now add that table model to your table and you are done :D
table.setModel(tableModel);
}
Try this:
while true ; do nc -l -p 1500 -c 'echo -e "HTTP/1.1 200 OK\n\n $(date)"'; done
The -c
makes netcat execute the given command in a shell, so you can use echo. If you don't need echo, use -e
. For further information on this, try man nc
. Note, that when using echo
there is no way for your program (the date
-replacement) to get the browser request. So you probably finally want to do something like this:
while true ; do nc -l -p 1500 -e /path/to/yourprogram ; done
Where yourprogram
must do the protocol stuff like handling GET, sending HTTP 200 etc.
Wrap the table in a DIV, set with the following style:

Ajax wont forward value to controller, and i just cant find an error :(
-JS
<script>
$(document).ready(function () {
$("#sMarka").change(function () {
var markaId = $(this).val();
alert(markaId);
debugger
$.ajax({
type:"POST",
url:"@Url.Action("VratiModele")",
dataType: "html",
data: { "markaId": markaId },
success: function (model) {
debugger
$("#sModel").empty();
$("#sModel").append(model);
}
});
});
});
</script>
--controller
public IActionResult VratiModele(int markaId = 0)
{
if (markaId != 0)
{
List<Model> listaModela = db.Modeli.Where(m => m.MarkaId == markaId).ToList();
ViewBag.ModelVozila = new SelectList(listaModela, "ModelId", "Naziv");

A lazy way of doing this if there are alot of tables to be deleted.
Get table using the below
Copy and paste the table names from the result set and paste it after the DROP command.
Given the following web.config:
<appSettings>
<add key="ClientId" value="127605460617602"/>
<add key="RedirectUrl" value="http://localhost:49548/Redirect.aspx"/>
</appSettings>
Example usage:
using System.Configuration;
string clientId = ConfigurationManager.AppSettings["ClientId"];
string redirectUrl = ConfigurationManager.AppSettings["RedirectUrl"];
if its something you wish to switch, fading one out and fading another in the same place, you can place a {position:absolute} attribute on the divs, so both the animations play on top of one another, and you don't have to wait for one animation to be over before starting up the next.
Double check your data types. The dotnet model binder will not convert a float to an integer (and I'm assuming other related concepts). This will cause the entire model to be rejected.
If you have json like this:
{
"shoeSize": 10.5
}
but your c# model looks like this:
class Shoe{
public int shoeSize;
}
the model binder will reject the model and you will get null.
clearfix
should contain the floating elements but in your html you have added clearfix
only after floating right that is your pull-right
so you should do like this:
<div class="clearfix">
<div id="sidebar">
<ul>
<li>A</li>
<li>A</li>
<li>C</li>
<li>D</li>
<li>E</li>
<li>F</li>
<li>...</li>
<li>Z</li>
</ul>
</div>
<div id="main">
<div>
<div class="pull-right">
<a>RIGHT</a>
</div>
</div>
<div>MOVED BELOW Z</div>
</div>
Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden;
as you have done in your main.
>>> lst = ['abcd', 'e', 'fg', 'hijklmn', 'opq', 'r']
>>> print [lst[2*i]+lst[2*i+1] for i in range(len(lst)/2)]
['abcde', 'fghijklmn', 'opqr']
Easiest way is to use System.Linq as previously described
using System.Linq;
public int GetHighestValue(List<MyTypes> list)
{
return list.Count > 0 ? list.Max(t => t.Age) : 0; //could also return -1
}
This is also possible with a Dictionary
using System.Linq;
public int GetHighestValue(Dictionary<MyTypes, OtherType> obj)
{
return obj.Count > 0 ? obj.Max(t => t.Key.Age) : 0; //could also return -1
}
I think you mean to update it back to the OLD
password, when the NEW one is not supplied.
DROP TRIGGER IF EXISTS upd_user;
DELIMITER $$
CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
FOR EACH ROW BEGIN
IF (NEW.password IS NULL OR NEW.password = '') THEN
SET NEW.password = OLD.password;
ELSE
SET NEW.password = Password(NEW.Password);
END IF;
END$$
DELIMITER ;
However, this means a user can never blank out a password.
DELIMITER $$
CREATE TRIGGER upd_user BEFORE UPDATE ON `user`
FOR EACH ROW BEGIN
IF (NEW.password IS NULL OR NEW.password = '' OR NEW.password = OLD.password) THEN
SET NEW.password = OLD.password;
ELSE
SET NEW.password = Password(NEW.Password);
END IF;
END$$
DELIMITER ;
Get rid of the semicolon after WordGame

You really should have discovered this problem when the class was a lot smaller. When you're writing code, you should be compiling about every time you add half a dozen lines.
type normal division first and then type shift + S->d
With design (based on problem). This is an alternate of divide-and-conquer. We'll first define an enum (considering it's only for an unsigned int).
public enum IntegerLength {
One((byte)1,10),
Two((byte)2,100),
Three((byte)3,1000),
Four((byte)4,10000),
Five((byte)5,100000),
Six((byte)6,1000000),
Seven((byte)7,10000000),
Eight((byte)8,100000000),
Nine((byte)9,1000000000);
byte length;
int value;
IntegerLength(byte len,int value) {
this.length = len;
this.value = value;
}
public byte getLenght() {
return length;
}
public int getValue() {
return value;
}
}
Now we'll define a class that goes through the values of the enum and compare and return the appropriate length.
public class IntegerLenght {
public static byte calculateIntLenght(int num) {
for(IntegerLength v : IntegerLength.values()) {
if(num < v.getValue()){
return v.getLenght();
}
}
return 0;
}
}
The run time of this solution is the same as the divide-and-conquer approach.
select into
is used in pl/sql to set a variable to field values. Instead, use
create table new_table as select * from old_table
If they are in the same controller class, it would be:
foreach ( $characters as $character) {
$num += $this->getFactorial($index) * $index;
$index ++;
}
Otherwise you need to create a new instance of the class, and call the method, ie:
$controller = new MyController();
foreach ( $characters as $character) {
$num += $controller->getFactorial($index) * $index;
$index ++;
}
$url = 'http://www.example.com';
$xml = simpleXML_load_file($url,"SimpleXMLElement",LIBXML_NOCDATA);
$url can be php file, as long as the file generate xml format data as output.
I prefer to use objcopy to convert to hex, then use diff.
This version, using the Windows API function MultiByteToWideChar()
, handles the memory allocation for arbitrarily long input strings.
int lenA = lstrlenA(input);
int lenW = ::MultiByteToWideChar(CP_ACP, 0, input, lenA, NULL, 0);
if (lenW>0)
{
output = new wchar_t[lenW];
::MultiByteToWideChar(CP_ACP, 0, input, lenA, output, lenW);
}
system
The system
method calls a system program. You have to provide the command as a string argument to this method. For example:
>> system("date")
Wed Sep 4 22:03:44 CEST 2013
=> true
The invoked program will use the current STDIN
, STDOUT
and STDERR
objects of your Ruby program. In fact, the actual return value is either true
, false
or nil
. In the example the date was printed through the IO object of STDIN
. The method will return true
if the process exited with a zero status, false
if the process exited with a non-zero status and nil
if the execution failed.
As of Ruby 2.6, passing exception: true
will raise an exception instead of returning false
or nil
:
>> system('invalid')
=> nil
>> system('invalid', exception: true)
Traceback (most recent call last):
...
Errno::ENOENT (No such file or directory - invalid)
Another side effect is that the global variable $?
is set to a Process::Status
object. This object will contain information about the call itself, including the process identifier (PID) of the invoked process and the exit status.
>> system("date")
Wed Sep 4 22:11:02 CEST 2013
=> true
>> $?
=> #<Process::Status: pid 15470 exit 0>
Backticks
Backticks (``) call a system program and return its output. As opposed to the first approach, the command is not provided through a string, but by putting it inside a backticks pair.
>> `date`
=> Wed Sep 4 22:22:51 CEST 2013
The global variable $?
is set through the backticks, too. With backticks you can also make use string interpolation.
%x()
Using %x
is an alternative to the backticks style. It will return the output, too. Like its relatives %w
and %q
(among others), any delimiter will suffice as long as bracket-style delimiters match. This means %x(date)
, %x{date}
and %x-date-
are all synonyms. Like backticks %x
can make use of string interpolation.
exec
By using Kernel#exec
the current process (your Ruby script) is replaced with the process invoked through exec
. The method can take a string as argument. In this case the string will be subject to shell expansion. When using more than one argument, then the first one is used to execute a program and the following are provided as arguments to the program to be invoked.
Open3.popen3
Sometimes the required information is written to standard input or standard error and you need to get control over those as well. Here Open3.popen3
comes in handy:
require 'open3'
Open3.popen3("curl http://example.com") do |stdin, stdout, stderr, thread|
pid = thread.pid
puts stdout.read.chomp
end
Microsoft recommends to use the "InstallShield Limited Edition for Visual Studio" as replacement for the discontinued "Deployment and Setup Project" - but it is not so nice and nobody else recommends to use it. But for simple setups, and if it is not a problem to relay on commercial third party products, you can use it.
The alternative is to use Windows Installer XML (WiX), but you have to do many things manually that did the Setup-Project by itself.
This may also be useful, so I thought I'd add it here.
If you would like to select a value based on the item's value and not the index of that item then you can do the following:
Your select list:
<select id="selectBox">
<option value="A">Number 0</option>
<option value="B">Number 1</option>
<option value="C">Number 2</option>
<option value="D">Number 3</option>
<option value="E">Number 4</option>
<option value="F">Number 5</option>
<option value="G">Number 6</option>
<option value="H">Number 7</option>
</select>
The jquery:
$('#selectBox option[value=C]').attr('selected', 'selected');
$('#selectBox option[value=C]').prop('selected', true);
The selected item would be "Number 2" now.
I found this piece of information and got it to work correctly. The data given to me was in string format so I needed to parse the string using kendo.parseDate
before formatting it with kendo.toString
.
columns: [

field: "FirstName",
title: "FIRST NAME"
},
{
field: "LastName",
title: "LAST NAME"
},
{
field: "DateOfBirth",
title: "DATE OF BIRTH",
template: "#= kendo.toString(kendo.parseDate(DateOfBirth, 'yyyy-MM-dd'), 'MM/dd/yyyy') #"
},
...
We now have a more modern way to do this work.
The java.time framework is bundled with Java 8 and later. See Tutorial. These new classes are inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project. They are a vast improvement over the troublesome old classes, java.util.Date/.Calendar et al.
Note that the 3-4 letter codes like EDT
are neither standardized nor unique. Avoid them whenever possible. Learn to use ISO 8601 standard formats instead. The java.time framework may take a stab at translating, but many of the commonly used codes have duplicate values.
By the way, note how java.time by default generates strings using the ISO 8601 formats but extended by appending the name of the time zone in brackets.
String input = "Thu Jun 18 20:56:02 EDT 2009";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern ( "EEE MMM d HH:mm:ss zzz yyyy" , Locale.ENGLISH );
ZonedDateTime zdt = formatter.parse ( input , ZonedDateTime :: from );
Dump to console.
System.out.println ( "zdt : " + zdt );
When run.
zdt : 2009-06-18T20:56:02-04:00[America/New_York]
For fun let's adjust to the India time zone.
ZonedDateTime zdtKolkata = zdt.withZoneSameInstant ( ZoneId.of ( "Asia/Kolkata" ) );
zdtKolkata : 2009-06-19T06:26:02+05:30[Asia/Kolkata]
If you really need a java.util.Date object for use with classes not yet updated to the java.time types, convert. Note that you are losing the assigned time zone, but have the same moment automatically adjusted to UTC.
java.util.Date date = java.util.Date.from( zdt.toInstant() );
Use:
docker inspect -f "{{.Name}} {{.Config.Cmd}}" $(docker ps -a -q)
... it does a "docker inspect" for all containers.
Incase you have multiple versions of Postgres installed on your machine. You can remove all via brew
command as:
brew uninstall --force postgresql
When you want to have cross component interaction, then you need to know what are @Input , @Output , EventEmitter and Subjects.
If the relation between components is parent- child or vice versa we use @input & @output with event emitter..
@output emits an event and you need to emit using event emitter.
If it's not parent child relationship.. then you have to use subjects or through a common service.
You can use this function:
function createStringArray(arr, prop) {
var result = [];
for (var i = 0; i < arr.length; i += 1) {
result.push(arr[i][prop]);
}
return result;
}
Just pass the array of objects and the property you need. The script above will work even in old EcmaScript implementations.
One more solution which is easy to understand :)
var newstring = mystring.split('.').join(' ');
I am not sure does it suit you but I noticed that tar
does not fail on changed/deleted files in pipe mode. See what I mean.
Test script:
#!/usr/bin/env bash
set -ex
tar cpf - ./files | aws s3 cp - s3://my-bucket/files.tar
echo $?
Deleting random files manually...
Output:
+ aws s3 cp - s3://my-bucket/files.tar
+ tar cpf - ./files
tar: ./files/default_images: File removed before we read it
tar: ./files: file changed as we read it
+ echo 0

If you have the DLL added to your project, you can open the csproj file and see the Reference tag.
Example:
<Reference Include="System.Web.Mvc, Version=3.0.0.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" />
The error message outlines the solution. The line
doNothing().when(cmd).dnsCheck(HOST, any(InetAddressFactory.class))
uses one raw value and one matcher, when it's required to use either all raw values or all matchers. A correct version might read
doNothing().when(cmd).dnsCheck(eq(HOST), any(InetAddressFactory.class))
#include <vector>
#include <algorithm>
int main()
{
int arr[5] = {4, 1, 3, 2, 6};
int x = -1;
std::vector<int> testVector(arr, arr + sizeof(arr) / sizeof(int) );
std::vector<int>::iterator it = std::find(testVector.begin(), testVector.end(), 3);
if (it != testVector.end())
{
x = it - testVector.begin();
}
return 0;
}
Or you can just build a vector in a normal way, without creating it from an array of ints and then use the same solution as shown in my example.
The way to keep SELECT dbo.fCalculateEstimateDate(647)
call working is:
ALTER function [dbo].[fCalculateEstimateDate] (@vWorkOrderID numeric)
Returns varchar(100) AS
Declare @Result varchar(100)
SELECT @Result = [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID,DEFAULT)
Return @Result
Begin
End
CREATE function [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID numeric,@ToDate DateTime=null)
Returns varchar(100) AS
Begin
<Function Body>
End
Use Joda-Time library

information is discarded in the compiling process. Even if a decompiler could produce the logical equivalent code with classes and everything (it probably can't), the self-documenting part is gone in optimized release code. No variable names, no routine names, no class names - just addresses.
The documentation for Gerrit, in particular the "Push changes" section, explains that you push to the "magical refs/for/'branch'
ref using any Git client tool".
The following image is taken from the Intro to Gerrit. When you push to Gerrit, you do git push gerrit HEAD:refs/for/<BRANCH>
. This pushes your changes to the staging area (in the diagram, "Pending Changes"). Gerrit doesn't actually have a branch called <BRANCH>
; it lies to the git client.
Internally, Gerrit has its own implementation for the Git and SSH stacks. This allows it to provide the "magical" refs/for/<BRANCH>
refs.
When a push request is received to create a ref in one of these namespaces Gerrit performs its own logic to update the database, and then lies to the client about the result of the operation. A successful result causes the client to believe that Gerrit has created the ref, but in reality Gerrit hasn’t created the ref at all. [Link - Gerrit, "Gritty Details"].
After a successful patch (i.e, the patch has been pushed to Gerrit, [putting it into the "Pending Changes" staging area], reviewed, and the review has passed), Gerrit pushes the change from the "Pending Changes" into the "Authoritative Repository", calculating which branch to push it into based on the magic it did when you pushed to refs/for/<BRANCH>
. This way, successfully reviewed patches can be pulled directly from the correct branches of the Authoritative Repository
.
Setting the event to null inside the class works. When you dispose a class you should always set the event to null, the GC has problems with events and may not clean up the disposed class if it has dangling events.
For those interested, Spring MVC (3.x at least) returns a 400 in this case, which seems wrong to me.
I tested several Google URLs (accounts.google.com) and removed required parameters, and they generally return a 404 in this case.
I would copy Google.
Firstly, you should check if your image column is BLOB type!
I don't know anything about your SQL table, but if I'll try to make my own as an example.
We got fields id
(int), image
(blob) and image_name
(varchar(64)).
So the code should look like this (assume ID is always '1' and let's use this mysql_query):
$image = addslashes(file_get_contents($_FILES['image']['tmp_name'])); //SQL Injection defence!
$image_name = addslashes($_FILES['image']['name']);
$sql = "INSERT INTO `product_images` (`id`, `image`, `image_name`) VALUES ('1', '{$image}', '{$image_name}')";
if (!mysql_query($sql)) { // Error handling
echo "Something went wrong! :(";
}
You are doing it wrong in many ways. Don't use mysql functions - they are deprecated! Use PDO or MySQLi. You should also think about storing files locations on disk. Using MySQL for storing images is thought to be Bad Ideaâ„¢. Handling SQL table with big data like images can be problematic.
Also your HTML form is out of standards. It should look like this:
<form action="insert_product.php" method="POST" enctype="multipart/form-data">
<label>File: </label><input type="file" name="image" />
<input type="submit" />
</form>
Sidenote:
When dealing with files and storing them as a BLOB, the data must be escaped using mysql_real_escape_string()
, otherwise it will result in a syntax error.
To iterate through the keys of an object, use a for .. in
loop:
for (var key in json_obj) {
if (json_obj.hasOwnProperty(key)) {
// do something with `key'
}
}
To test all elements for empty children, you can use a recursive approach: iterate through all elements and recursively test their children too.
Removing a property of an object can be done by using the delete
keyword:
var someObj = {
"one": 123,
"two": 345
};
var key = "one";
delete someObj[key];
console.log(someObj); // prints { "two": 345 }
Documentation:
I found that calling of stored procedures in code-first approach is not convenient.
I prefer to use Dapper
instead.
The following code was written with Entity Framework:
var clientIdParameter = new SqlParameter("@ClientId", 4);
var result = context.Database
.SqlQuery<ResultForCampaign>("GetResultsForCampaign @ClientId", clientIdParameter)
.ToList();
The following code was written with Dapper
:
return Database.Connection.Query<ResultForCampaign>(
"GetResultsForCampaign ",
new
{
ClientId = 4
},
commandType: CommandType.StoredProcedure);
I believe the second piece of code is simpler to understand.
The DateTimeFormatInfo class implements this interface, so it allows you to control the formatting of your DateTime strings.
I am answering this for android studio 2.3.1. One of the easiest ways to set RelativeLayout as default layout is going to text mode and editing the XML file as follows:
Change this line:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
To
<android.widget.RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
And do check your ending tag changes to this:
</android.widget.RelativeLayout>
Also (optionally) go ahead and delete this line if it's being shown in grey:
xmlns:app="http://schemas.android.com/apk/res-auto"
Edit:
This is an optional change to make in project, I came across this tip while going through Udacity's Android Developer Course
If the constraint layout is not needed in the project remove the following dependency from build.gradle by deleting this line and then doing gradle sync:
compile 'com.android.support.constraint:constraint-layout:1.0.0-beta4'
All you need is to set values first to your RadioButton, for example:
RadioButton radioButton = (RadioButton)findViewById(R.id.radioButton);
radioButton.setId(1); //some int value
and then whenever this spacific radioButton will be chosen you can pull its value by the Id you gave it with
RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radioGroup);
int whichIndex = radioGroup.getCheckedRadioButtonId(); //of course the radioButton
//should be inside the "radioGroup"
//in the XML
Cheers!
There's a clone snippet here, which you can add to your model which does this:
def clone(self):
new_kwargs = dict([(fld.name, getattr(old, fld.name)) for fld in old._meta.fields if fld.name != old._meta.pk]);
return self.__class__.objects.create(**new_kwargs)
If you have a class with an object property, or if your property actually casts to an object, you can reshape the object by reassigning its properties, as in:
MyClass varClass = new MyClass();
varClass.propObjectProperty = new { Id = 1, Description = "test" };
//if you need to treat the class as an object
var varObjectProperty = ((dynamic)varClass).propObjectProperty;
((dynamic)varClass).propObjectProperty = new { Id = varObjectProperty.Id, Description = varObjectProperty.Description, NewDynamicProperty = "new dynamic property description" };
//if your property is an object, instead
var varObjectProperty = varClass.propObjectProperty;
varClass.propObjectProperty = new { Id = ((dynamic)varObjectProperty).Id, Description = ((dynamic)varObjectProperty).Description, NewDynamicProperty = "new dynamic property description" };
With this approach, you basically rewrite the object property adding or removing properties as if you were first creating the object with the
new { ... }
syntax.
In your particular case, you're probably better off creating an actual object to which you assign properties like "dob" and "address" as if it were a person, and at the end of the process, transfer the properties to the actual "Person" object.
<xsl:call-template>
is a close equivalent to calling a function in a traditional programming language.
You can define functions in XSLT, like this simple one that outputs a string.
<xsl:template name="dosomething">
<xsl:text>A function that does something</xsl:text>
</xsl:template>
This function can be called via <xsl:call-template name="dosomething">
.
<xsl:apply-templates>
is a little different and in it is the real power of XSLT: It takes any number of XML nodes (whatever you define in the select
attribute), iterates them (this is important: apply-templates works like a loop!) and finds matching templates for them:
<!-- sample XML snippet -->
<xml>
<foo /><bar /><baz />
</xml>
<!-- sample XSLT snippet -->
<xsl:template match="xml">
<xsl:apply-templates select="*" /> <!-- three nodes selected here -->
</xsl:template>
<xsl:template match="foo"> <!-- will be called once -->
<xsl:text>foo element encountered</xsl:text>
</xsl:template>
<xsl:template match="*"> <!-- will be called twice -->
<xsl:text>other element countered</xsl:text>
</xsl:template>
This way you give up a little control to the XSLT processor - not you decide where the program flow goes, but the processor does by finding the most appropriate match for the node it's currently processing.
If multiple templates can match a node, the one with the more specific match expression wins. If more than one matching template with the same specificity exist, the one declared last wins.
You can concentrate more on developing templates and need less time to do "plumbing". Your programs will become more powerful and modularized, less deeply nested and faster (as XSLT processors are optimized for template matching).
A concept to understand with XSLT is that of the "current node". With <xsl:apply-templates>
the current node moves on with every iteration, whereas <xsl:call-template>
does not change the current node. I.e. the .
within a called template refers to the same node as the .
in the calling template. This is not the case with apply-templates.
This is the basic difference. There are some other aspects of templates that affect their behavior: Their mode
and priority
, the fact that templates can have both a name
and a match
. It also has an impact whether the template has been imported (<xsl:import>
) or not. These are advanced uses and you can deal with them when you get there.
Is this what you are looking for ?

If you have global environment variables defined outside Gradle,
test {
environment "ENV_VAR", System.getenv('ENV_VAR')
useJUnitPlatform()
}
Or you can use simply preload="none"
attribute to make VIDEO background visible. And you can use background-size: cover;
here.
video {
background: transparent url('video-image.jpg') 50% 50% / cover no-repeat ;
}
<video preload="none" controls>
<source src="movie.mp4" type="video/mp4">
<source src="movie.ogg" type="video/ogg">

Here is very handy directive angular-datetime. You can use it like this:
<input type="text" datetime="yyyy-MM-dd HH:mm:ss" ng-model="myDate">
It also add mask to your input and perform validation.
My complete solution:
1) Get Dark Reader on chrome which will not only get you a great Dark Theme for Jupyter but also for every single website you'd like (you can play with the different filters. I use Dynamic).
2) Paste those lines of code in your notebook so the legends and axes become visible:
from jupyterthemes import jtplot
jtplot.style(theme='monokai', context='notebook', ticks=True, grid=False)
You're all set for a disco coding night !
net stop <your service> && net start <your service>
No net restart
, unfortunately.
You can wrap it in your own function:
function isNullAndUndef(variable) {
return (variable !== null && variable !== undefined);
}
In my case, I was defining a bean and autowiring it in the constructor of the same class file.
@SpringBootApplication
public class MyApplication {
private MyBean myBean;
public MyApplication(MyBean myBean) {
this.myBean = myBean;
}
@Bean
public MyBean myBean() {
return new MyBean();
}
}
My solution was to move the bean definition to another class file.
@Configuration
public CustomConfig {
@Bean
public MyBean myBean() {
return new MyBean();
}
}
$("span").mouseover(function () {
$(this).css({"background-color":"green","font-size":"20px","color":"red"});
});

Take the solution. I have written this code in an easy format:
const insertWord = (sentence,word,index) => {
var sliceWord = word.slice(""),output = [],join; // Slicing the input word and declaring other variables
var sliceSentence = sentence.slice(""); // Slicing the input sentence into each alphabets
for (var i = 0; i < sliceSentence.length; i++)
{
if (i === index)
{ // checking if index of array === input index
for (var j = 0; j < word.length; j++)
{ // if yes we'll insert the word
output.push(sliceWord[j]); // Condition is true we are inserting the word
}
output.push(" "); // providing a single space at the end of the word
}
output.push(sliceSentence[i]); // pushing the remaining elements present in an array
}
join = output.join(""); // converting an array to string
console.log(join)
return join;
}
This is working for me using this Bootsrap Datetimepiker, it returns the value as it is shown in the datepicker input, e.g. 2019-04-11
$('#myDateTimePicker').on('click,focusout', function (){
var myDate = $("#myDateTimePicker").val();
//console.log(myDate);
//alert(myDate);
});
he does an integer divide, which means 3 / 4 = 0. cast one of the brackets to float
(float)(a.y - b.y) / (a.x - b.x);
Polymorphism is the ability to:
Invoke an operation on an instance of a specialized type by only knowing its generalized type while calling the method of the specialized type and not that of the generalized type: it is dynamic polymorphism.
Define several methods having the save name but having differents parameters: it is static polymorphism.
The first if the historical definition and the most important.
It allows to create strongly-typed consistency of the class hierarchy and to do some magical things like managing lists of objects of differents types without knowing their types but only one of their parent type, as well as data bindings.
Here are some Shapes like Point, Line, Rectangle and Circle having the operation Draw() taking either nothing or either a parameter to set a timeout to erase it.
public class Shape
{
public virtual void Draw()
{
DoNothing();
}
public virtual void Draw(int timeout)
{
DoNothing();
}
}
public class Point : Shape
{
int X, Y;
public override void Draw()
{
DrawThePoint();
}
}
public class Line : Point
{
int Xend, Yend;
public override Draw()
{
DrawTheLine();
}
}
public class Rectangle : Line
{
public override Draw()
{
DrawTheRectangle();
}
}
var shapes = new List<Shape> { new Point(0,0), new Line(0,0,10,10), new rectangle(50,50,100,100) };
foreach ( var shape in shapes )
shape.Draw();
Here the Shape class and the Shape.Draw() methods should be marked as abstract.
They are not for to make understand.
Without polymorphism, using abstract-virtual-override, while parsing the shapes, it is only the Spahe.Draw() method that is called as the CLR don't know what method to call. So it call the method of the type we act on, and here the type is Shape because of the list declaration. So the code do nothing at all.
With polymorphism, the CLR is able to infer the real type of the object we act on using what is called a virtual table. So it call the good method, and here calling Shape.Draw() if Shape is Point calls the Point.Draw(). So the code draws the shapes.
Polymorphism in Java (Level 2)
you can add values to specific columns as well, just specify the column names in which you like to add corresponding values:
Insert into Table (Col1, Col2, Col4,col5,Col7) Values ('Va11','Va2','Val4','Val5','Val7');
Make sure the columns you skip dont have not null value type.
You can only access cookies for a specific site. Using document.cookie
you will get a list of escaped key=value pairs seperated by a semicolon.
secret=do%20not%20tell%you;last_visit=1225445171794
To simplify the access, you have to parse the string and unescape all entries:
var getCookies = function(){
var pairs = document.cookie.split(";");
var cookies = {};
for (var i=0; i<pairs.length; i++){
var pair = pairs[i].split("=");
cookies[(pair[0]+'').trim()] = unescape(pair.slice(1).join('='));
}
return cookies;
}
So you might later write:
var myCookies = getCookies();
alert(myCookies.secret); // "do not tell you"
If it's reconnecting and getting connection ID 2, the server has almost definitely just crashed.
Contact the server admin and get them to diagnose the problem. No non-malicious SQL should crash the server, and the output of mysqldump certainly should not.
It is probably the case that the server admin has made some big operational error such as assigning buffer sizes of greater than the architecture's address-space limits, or more than virtual memory capacity. The MySQL error-log will probably have some relevant information; they will be monitoring this if they are competent anyway.
Check out iText; it is a pure Java PDF toolkit which has support for reading data from HTML. I used it recently in a project when I needed to pull content from our CMS and export as PDF files, and it was all rather straightforward. The support for CSS and style tags is pretty limited, but it does render tables without any problems (I never managed to set column width though).
Creating a PDF from HTML goes something like this:
Document doc = new Document(PageSize.A4);
PdfWriter.getInstance(doc, out);
doc.open();
HTMLWorker hw = new HTMLWorker(doc);
hw.parse(new StringReader(html));
doc.close();
TL;DR
In several occasions, I've solved this kind of errors by just closing my terminal session and opening a new one before retrying the failing command.
Long explanation
In some SOs (such as MacOS) there is already a pre-installed, system-wide version of ruby. If you are using a version manager, such as rbenv
or asdf
, they work by playing with the environment of your current session so that the relevant commands point to the binaries installed by the version manager.
When installing a new binary, the version manager installs it in a special location, usually somewhere under the user's home directory. It then configures everything in your PATH
so that you get the freshly installed binaries when you issue a command, instead of the ones that came with your system. However, if you don't restart the session (there are other ways of getting your environment updated, but that's the easiest one) you don't get the new configuration and you will be using the original installation.
i made a method that merge cells and put border.
protected void setMerge(Sheet sheet, int numRow, int untilRow, int numCol, int untilCol, boolean border) {
CellRangeAddress cellMerge = new CellRangeAddress(numRow, untilRow, numCol, untilCol);
sheet.addMergedRegion(cellMerge);
if (border) {
setBordersToMergedCells(sheet, cellMerge);
}
}
protected void setBordersToMergedCells(Sheet sheet, CellRangeAddress rangeAddress) {
RegionUtil.setBorderTop(BorderStyle.MEDIUM, rangeAddress, sheet);
RegionUtil.setBorderLeft(BorderStyle.MEDIUM, rangeAddress, sheet);
RegionUtil.setBorderRight(BorderStyle.MEDIUM, rangeAddress, sheet);
RegionUtil.setBorderBottom(BorderStyle.MEDIUM, rangeAddress, sheet);
}
Generally it is that you are inserting a value that is greater than the maximum allowed value. Ex, data column can only hold up to 200 characters, but you are inserting 201-character string
There's no need for you to use super-call of the ActionBarDrawerToggle
which requires the Toolbar. This means instead of using the following constructor:
ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)
You should use this one:
ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)
So basically the only thing you have to do is to remove your custom drawable
:
super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);
More about the "new" ActionBarDrawerToggle in the Docs (click).
As an Anaconda user, I wanted to find one or two appropriate commands to solve the problem. Fortunately, this answer helped. For conda 4.5.11 (use conda -V
to check Anaconda version) I have performed next steps:
# Python version does not matter, most likely, check yourself
conda create -n myenv python=3.6
conda activate myenv
conda install -c menpo opencv
That will install OpenCV 2.4.11. Anaconda's another command conda install -c menpo opencv3
will install OpenCV3, but Python has to be downgraded to 2.7. To install OpenCV3 with Python3 use next (due to the first link):
conda create -n myenv python
pip install opencv-python==3.4.2.16
pip install opencv-contrib-python==3.4.2.16
Check the SIFT:
conda activate myenv
python
>>> cv2.xfeatures2d.SIFT_create()
<xfeatures2d_SIFT 000002A3478655B0>
HTML :
<div id="myDiv">

$("#myDiv form#myForm").html(chbx);
//to insert dynamically created form
$("#myDiv").html("<form id='dynamicForm'>" +chbx + "'</form>");
It would be better to use standard and famous libraries instead of writing the code from scratch.
Using these libraries you can generate a JWT token and sign it using RS256 as below.
public string GenerateJWTToken(string rsaPrivateKey)
{
var rsaParams = GetRsaParameters(rsaPrivateKey);
var encoder = GetRS256JWTEncoder(rsaParams);
// create the payload according to the Google's doc
var payload = new Dictionary<string, object>
{
{ "iss", ""},
{ "sub", "" },
// and other key-values according to the doc
};
// add headers. 'alg' and 'typ' key-values are added automatically.
var header = new Dictionary<string, object>
{
{ "kid", "{your_private_key_id}" },
};
var token = encoder.Encode(header,payload, new byte[0]);
return token;
}
private static IJwtEncoder GetRS256JWTEncoder(RSAParameters rsaParams)
{
var csp = new RSACryptoServiceProvider();
csp.ImportParameters(rsaParams);
var algorithm = new RS256Algorithm(csp, csp);
var serializer = new JsonNetSerializer();
var urlEncoder = new JwtBase64UrlEncoder();
var encoder = new JwtEncoder(algorithm, serializer, urlEncoder);
return encoder;
}
private static RSAParameters GetRsaParameters(string rsaPrivateKey)
{
var byteArray = Encoding.ASCII.GetBytes(rsaPrivateKey);
using (var ms = new MemoryStream(byteArray))
{
using (var sr = new StreamReader(ms))
{
// use Bouncy Castle to convert the private key to RSA parameters
var pemReader = new PemReader(sr);
var keyPair = pemReader.ReadObject() as AsymmetricCipherKeyPair;
return DotNetUtilities.ToRSAParameters(keyPair.Private as RsaPrivateCrtKeyParameters);
}
}
}
ps: the RSA private key should have the following format:
-----BEGIN RSA PRIVATE KEY----- {base64 formatted value} -----END RSA PRIVATE KEY-----
You have referenced the image as a path on your computer (C:\etc\etc)......is it located there? You didn't answer what others have asked. I have taken your code, placed it in dreamweaver and it works apart from the image as I don't have that stored.
Check the location and then let us know.
Since no-one mentioned the %
operator yet, here comes. It only does truncation, and you cannot rely on the return value not to have floating point inaccuracies, but sometimes it's handy:

res4: Double = 1.23

A picture is worth a thousand words:
The key is:
document.documentElement.scrollTo({
left: 0,
top: document.documentElement.scrollHeight - document.documentElement.clientHeight,
behavior: 'smooth'
});
It is using document.documentElement
, which is the <html>
element. It is just like using window
, but it is just my personal preference to do it this way, because if it is not the whole page but a container, it works just like this except you'd change document.body
and document.documentElement
to document.querySelector("#container-id")
.

To solve this either you down-grade the Django
to any version lesser than 2.0.
pip
install Django==1.11.29
.
For update SQLs:
update Table1 set Col1 = Col2 / ISNULL(NULLIF(Col3,0),1)
That is correct behaviour, it's up to you to create the contents for the 404 page.
The 404 header is used by spiders and download-managers to determine if the file exists.
(A page with a 404 header won't be indexed by google or other search-engines)
Normal users however don't look at http-headers and use the page as a normal page.
I had that same problem but in case that I was adding en element into iterated list. I made it this way
public static void remove(Integer remove) {
for(int i=0; i<integerList.size(); i++) {
//here is maybe fine to deal with integerList.get(i)==null
if(integerList.get(i).equals(remove)) {
integerList.remove(i);
}
}
}
Now everything goes fine because you don't create any iterator over your list, you iterate over it "manually". And condition i < integerList.size()
will never fool you because when you remove/add something into List size of the List decrement/increment..
Hope it helps, for me that was solution.
Your should create ptr as follows:
char *ptr;
You have created ptr as an array of pointers to chars. The above creates a single pointer to a char.
Edit: complete code should be:
char *ptr;
char arr[5] = {'a','b','c','d','e'};
ptr = arr;
printf("\nvalue:%c", *(ptr+0));
I'm not sure, but I would guess they tested some sample of prime numbers and found that 31 gave the best distribution over some sample of possible Strings.
In Android Studio, go to app -> src -> main -> java -> com.example.username.projectname
Right click on com.example.username.projectname -> Activity -> ActivityType
Fill in the details of the New Android Activity and click Finish.
Viola! new activity added to the existing project.
An N-tier application is an application which has more than three components involved. What are those components?
All the social applications like Instagram, Facebook, large scale industry services like Uber, Airbnb, online massive multiplayer games like Pokemon Go, applications with fancy features are n-tier applications.
Options -Indexes returns a 403 forbidden error for a protected directory. The same behaviour can be achived by using the following Redirect in htaccess :
RedirectMatch 403 ^/folder/?$
This will return a forbidden error for example.com/folder/ .
You can also use mod-rewrite to forbid a request for folder.
RewriteEngine on
RewriteRule ^folder/?$ - [F]
If your htaccess is in the folder that you are going to forbid , change RewriteRule's pattern from ^folder/?$ to ^$ .
A successful Git branching model by Vincent Driessen has good suggestions. A picture is below. If this branching model appeals to you consider the flow extension to git. Others have commented about flow
Driessen's model includes
A master branch, used only for release. Typical name master
.
A "develop" branch off of that branch. That's the one used for most main-line work. Commonly named develop
.
Multiple feature branches off of the develop branch. Name based on the name of the feature. These will be merged back into develop, not into the master or release branches.
Release branch to hold candidate releases, with only bug fixes and no new features. Typical name rc1.1
.
Hotfixes are short-lived branches for changes that come from master and will go into master without development branch being involved.
you need to replace path with the help of replace function.
update table_name set column_name = replace(column_name, 'oldstring', 'newstring')
here column_name
refers to that column which you want to change.
Hope it will work.
Use $.on()
to bind your chosen event to the input, don't use the shortcuts like $.keydown()
etc because as of jQuery 1.7 $.on()
is the preferred method to attach event handlers (see here: http://api.jquery.com/on/ and http://api.jquery.com/bind/).
$.keydown()
is just a shortcut to $.bind('keydown')
, and $.bind()
is what $.on()
replaces (among others).
To answer your question, as far as I'm aware, unless you need to fire an event on keydown
specifically, the change
event should do the trick for you.
$('element').on('change', function(){
console.log('change');
});
To respond to the below comment, the javascript change
event is documented here: https://developer.mozilla.org/en-US/docs/Web/Events/change
And here is a working example of the change
event working on an input element, using jQuery: http://jsfiddle.net/p1m4xh08/
Adding to Eric Jablow's answer, here is a possible solution (it worked for me - linux mint 14 /nadia)
find /path/to/search/ -type f -name "glob-to-find-files" | xargs cp -t /target/path/
You can refer to "How can I use xargs to copy files that have spaces and quotes in their names?" as well.
I would like to do this without attaching a class to every td
Personally, I would go with the the class-on-each-td/th/col approach. Then you can switch columns on and off using a single write to className on the container, assuming style rules like:
table.hide1 .col1 { display: none; }
table.hide2 .col2 { display: none; }
...
This is going to be faster than any JS loop approach; for really long tables it can make a significant difference to responsiveness.
If you can get away with not supporting IE6, you could use adjacency selectors to avoid having to add the class attributes to tds. Or alternatively, if your concern is making the markup cleaner, you could add them from JavaScript automatically in an initialisation step.
You can apply the atuto_increment constraint to the data column by the following query:
ALTER TABLE customers MODIFY COLUMN customer_id BIGINT NOT NULL AUTO_INCREMENT;
But, if the columns are part of a foreign key constraint you, will most probably receive an error. Therefore, it is advised to turn off foreign_key_checks by using the following query:
SET foreign_key_checks = 0;
Therefore, use the following query instead:
SET foreign_key_checks = 0;
ALTER TABLE customers MODIFY COLUMN customer_id BIGINT NOT NULL AUTO_INCREMENT;
SET foreign_key_checks = 1;
While I agree with Tim and Oben Sonne that you should use an XML library, there are ways to still manipulate it as a simple string object.
I likely would not try to use a single file pointer for what you are describing, and instead read the file into memory, edit it, then write it out.:
inFile = open('file.xml', 'r')
data = inFile.readlines()
inFile.close()
# some manipulation on `data`
outFile = open('file.xml', 'w')
outFile.writelines(data)
outFile.close()
You can also use window.location.href=window.location.href;
I think you can use loc
if you need update two columns to same value:
df1.loc[df1['stream'] == 2, ['feat','another_feat']] = 'aaaa'
print df1
stream feat another_feat
a 1 some_value some_value
b 2 aaaa aaaa
c 2 aaaa aaaa
d 3 some_value some_value
If you need update separate, one option is use:
df1.loc[df1['stream'] == 2, 'feat'] = 10
print df1
stream feat another_feat
a 1 some_value some_value
b 2 10 some_value
c 2 10 some_value
d 3 some_value some_value
Another common option is use numpy.where
:
df1['feat'] = np.where(df1['stream'] == 2, 10,20)
print df1
stream feat another_feat
a 1 20 some_value
b 2 10 some_value
c 2 10 some_value
d 3 20 some_value
EDIT: If you need divide all columns without stream
where condition is True
, use:
print df1
stream feat another_feat
a 1 4 5
b 2 4 5
c 2 2 9
d 3 1 7
#filter columns all without stream
cols = [col for col in df1.columns if col != 'stream']
print cols
['feat', 'another_feat']
df1.loc[df1['stream'] == 2, cols ] = df1 / 2
print df1
stream feat another_feat
a 1 4.0 5.0
b 2 2.0 2.5
c 2 1.0 4.5
d 3 1.0 7.0
If working with multiple conditions is possible use multiple numpy.where
or numpy.select
:
df0 = pd.DataFrame({'Col':[5,0,-6]})
df0['New Col1'] = np.where((df0['Col'] > 0), 'Increasing',
np.where((df0['Col'] < 0), 'Decreasing', 'No Change'))
df0['New Col2'] = np.select([df0['Col'] > 0, df0['Col'] < 0],
['Increasing', 'Decreasing'],
default='No Change')
print (df0)
Col New Col1 New Col2
0 5 Increasing Increasing
1 0 No Change No Change
2 -6 Decreasing Decreasing
Very simple code to make jquery slider Here is two div first is the slider viewer and second is the image list container. Just copy paste the code and customise with css.
<div class="featured-image" style="height:300px">

</div>
<div class="post-margin" style="margin:10px 0px; padding:0px;" id="thumblist">
<img src='01.jpg'>

<img src='03.jpg'>
<img src='04.jpg'>
</div>
<script type="text/javascript">
function changeThumbnail()
{

var path=$("#thumbnail").attr('src');
var arr= new Array(); var i=0;
$("#thumblist img").each(function(index, element) {
arr[i]=$(this).attr('src');
i++;
});
var index= arr.indexOf(path);
if(index==(arr.length-1))
path=arr[0];
else
path=arr[index+1];
$("#thumbnail").attr('src',path).fadeIn(200);
setTimeout(changeThumbnail, 5000);
}

Since everyone has given you the JavaScript answer you've asked for, I'll throw in that the CSS property text-transform: capitalize
will do exactly this.
I realize this might not be what you're asking for - you haven't given us any of the context in which you're running this - but if it's just for presentation, I'd definitely go with the CSS alternative.
You need to download the java-openjfx package from the official Arch Linux repos. (Also, make sure you have the openjdk8-openjdk package). After doing that, open your project in Intellij and go to Project-Structure -> SDKs -> 1.8 -> Classpath and try removing the old JDK you had and clicking on the directory for the new JDK that will now contain jfxrt.jar.
If you want very few info like a class in your html for common browsers for instance, you could use:
function get_browser()
{
$browser = '';
$ua = strtolower($_SERVER['HTTP_USER_AGENT']);
if (preg_match('~(?:msie ?|trident.+?; ?rv: ?)(\d+)~', $ua, $matches)) $browser = 'ie ie'.$matches[1];
elseif (preg_match('~(safari|chrome|firefox)~', $ua, $matches)) $browser = $matches[1];
return $browser;
}
which will return 'safari' or 'firefox' or 'chrome', or 'ie ie8', 'ie ie9', 'ie ie10', 'ie ie11'.
Try:
$counter = 0;
foreach ($Contents as $item) {
something
your code ...
$counter++;
}
$total_count=$counter-1;
If you want the full range of public and private functions with the ability for public functions to access private functions, layout code for an object like this:
function MyObject(arg1, arg2, ...) {
//constructor code using constructor arguments...
//create/access public variables as
// this.var1 = foo;
//private variables
var v1;
var v2;
//private functions
function privateOne() {
}
function privateTwon() {
}
//public functions
MyObject.prototype.publicOne = function () {
};
MyObject.prototype.publicTwo = function () {
};
}
I wrote a script that does this:
function! WrapSelect (front)
"puts characters around the selected text.
let l:front = a:front
if (a:front == '[')
let l:back = ']'
elseif (a:front == '(')
let l:back = ')'
elseif (a:front == '{')
let l:back = '}'
elseif (a:front == '<')
let l:back = '>'
elseif (a:front =~ " ")
let l:split = split(a:front)
let l:back = l:split[1]
let l:front = l:split[0]
else
let l:back = a:front
endif
"execute: concat all these strings. '.' means "concat without spaces"
"norm means "run in normal mode and also be able to use \<C-x> characters"
"gv means "get the previous visual selection back up"
"c means "cut visual selection and go to insert mode"
"\<C-R> means "insert the contents of a register. in this case, the
"default register"
execute 'norm! gvc' . l:front. "\<C-R>\"" . l:back
endfunction
vnoremap <C-l> :<C-u>call WrapSelect(input('Wrapping? Give both (space separated) or just the first one: '))<cr>
To use, just highlight something, hit control l, and then type a character. If it's one of the characters the function knows about, it'll provide the correct terminating character. If it's not, it'll use the same character to insert on both sides.
Surround.vim can do more than just this, but this was sufficient for my needs.
Use a controller method if you need to run arbitrary JavaScript code, or you could define a filter that returned true or false.
I just tested (should have done that first), and something like ng-show="!a && b"
worked as expected.
You may also use the super
keyword in the sub class when you want to invoke a method from the parent class when you have overridden it in the subclass.
Example:
public class CellPhone {
public void print() {
System.out.println("I'm a cellphone");
}
}
public class TouchPhone extends CellPhone {
@Override
public void print() {
super.print();
System.out.println("I'm a touch screen cellphone");
}
public static void main (strings[] args) {
TouchPhone p = new TouchPhone();
p.print();
}
}
Here, the line super.print()
invokes the print()
method of the superclass CellPhone
. The output will be:
I'm a cellphone
I'm a touch screen cellphone
There are two approaches that I know of. The first is to tell the browser not to cache the page. Setting the Response to no cache takes care of that, however as you suspect the browser will often ignore this directive. The other approach is to set the date time of your response to a point in the future. I believe all browsers will correct this to the current time when they add the page to the cache, but it will show the page as newer when the comparison is made. I believe there may be some cases where a comparison is not made. I am not sure of the details and they change with each new browser release. Final note I have had better luck with pages that "refresh" themselves (another response directive). The refresh seems less likely to come from the cache.
Hope that helps.
Search for [ ]{2,}
. This will find two or more adjacent spaces anywhere within the line. It will also match leading and trailing spaces as well as lines that consist entirely of spaces. If you don't want that, check out Alexander's answer.
Actually, you can leave out the brackets, they are just for clarity (otherwise the space character that is being repeated isn't that well visible :)).
The problem with \s{2,}
is that it will also match newlines on Windows files (where newlines are denoted by CRLF
or \r\n
which is matched by \s{2}
.
If you also want to find multiple tabs and spaces, use [ \t]{2,}
.
Well, personally I do not use numeric datatype to store phone numbers or related info.
How do you store a number say 001234567? It'll end up as 1234567, losing the leading zeros.
Of course you can always left-pad it up, but that's provided you know exactly how many digits the number should be.
This doesn't answer your entire post,
Just my 2 cents
Disable back buttton in android
@Override
public void onBackPressed() {
return;
}
those are miliseconds, just divide them by 1000, since gmtime expects seconds ...
time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(1236472051807/1000.0))
To return a value from a VBScript function, assign the value to the name of the function, like this:
Function getNumber
getNumber = "423"
End Function
I'm creating a jQTouch app in PhoneGap for the iPhone. I've been battling with this issue for days. I've seen the eventlistener solution suggested a few times, but just could not get it to work.
In the end I came up with a different solution. It basically checks the width of the body periodically using settimeout. If the width is 320 then the orientation is portrait, if 480 then landscape. Then, if the orientation has changed since the last check, it will fire either a portrait stuff function or a landscape stuff function where you can do your thing for each orientation.
Code (note, I know there is some repetition in the code, just haven't bothered to trim it down yet!):
// get original orientation based on body width
deviceWidth = $('body').width();
if (deviceWidth == 320) {
currentOrientation = "portrait";
}
else if (deviceWidth == 480) {
currentOrientation = "landscape";
}
// fire a function that checks the orientation every x milliseconds
setInterval(checkOrientation, 500);
// check orientation
function checkOrientation() {
deviceWidth = $('body').width();
if (deviceWidth == '320') {
newOrientation = "portrait";
}
else if (deviceWidth == '480') {
newOrientation = "landscape";
}
// if orientation changed since last check, fire either the portrait or landscape function
if (newOrientation != currentOrientation) {
if (newOrientation == "portrait") {
changedToPortrait();
}
else if (newOrientation == "landscape") {
changedToLandscape();
}
currentOrientation = newOrientation;
}
}
// landscape stuff
function changedToLandscape() {
alert('Orientation has changed to Landscape!');
}
// portrait stuff
function changedToPortrait() {
alert('Orientation has changed to Portrait!');
}
MailKit is an Open Source cross-platform .NET mail-client library that is based on MimeKit and optimized for mobile devices. It has more and advance features better than System.Net.Mail Microsoft TNEF support via MimeKit.
Download nuget package from here.
See this example you can send mail
MimeMessage mailMessage = new MimeMessage();
mailMessage.From.Add(new MailboxAddress(senderName, [email protected]));
mailMessage.Sender = new MailboxAddress(senderName, [email protected]);
mailMessage.To.Add(new MailboxAddress(emailid, emailid));
mailMessage.Subject = subject;
mailMessage.ReplyTo.Add(new MailboxAddress(replyToAddress));
mailMessage.Subject = subject;
var builder = new BodyBuilder();
builder.TextBody = "Hello There";
try
{
using (var smtpClient = new SmtpClient())
{
smtpClient.Connect("HostName", "Port", MailKit.Security.SecureSocketOptions.None);
smtpClient.Authenticate("[email protected]", "password");
smtpClient.Send(mailMessage);
Console.WriteLine("Success");
}
}
catch (SmtpCommandException ex)
{
Console.WriteLine(ex.ToString());
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());

I found a better answer by Kenneth Fisher. The following query returns only currently running jobs:
SELECT
ja.job_id,
j.name AS job_name,
ja.start_execution_date,
ISNULL(last_executed_step_id,0)+1 AS current_executed_step_id,
Js.step_name
FROM msdb.dbo.sysjobactivity ja
LEFT JOIN msdb.dbo.sysjobhistory jh ON ja.job_history_id = jh.instance_id
JOIN msdb.dbo.sysjobs j ON ja.job_id = j.job_id
JOIN msdb.dbo.sysjobsteps js
ON ja.job_id = js.job_id
AND ISNULL(ja.last_executed_step_id,0)+1 = js.step_id
WHERE
ja.session_id = (
SELECT TOP 1 session_id FROM msdb.dbo.syssessions ORDER BY agent_start_date DESC
)
AND start_execution_date is not null
AND stop_execution_date is null;
You can get more information about a job by adding more columns from msdb.dbo.sysjobactivity
table in select clause.
I found this solution very helpful in a clean way to remove xml configuration entirely.
Please check this db configuration using JNDI and spring framework. http://www.unotions.com/design/how-to-create-oracleothersql-db-configuration-using-spring-and-maven/
By this article, it explain how easy to create a db confguration based on database jndi(db/test) configuration. once you are done with configuration then all the db repositories are loaded using this jndi. I did find useful. If @Pierre has issue with this then let me know. It's complete solution to write db configuration.
When processing ls -n
output, as an alternative to ill-portable shell arrays, you can use the positional arguments, which form the only array and are the only local variables in standard shell. Wrap the overwrite of positional arguments in a function to preserve the original arguments to your script or function.
getsize() { set -- $(ls -dn "$1") && echo $5; }
getsize FILE
This splits the output of ln -dn
according to current IFS
environment variable settings, assigns it to positional arguments and echoes the fifth one. The -d
ensures directories are handled properly and the -n
assures that user and group names do not need to be resolved, unlike with -l
. Also, user and group names containing whitespace could theoretically break the expected line structure; they are usually disallowed, but this possibility still makes the programmer stop and think.
In csh (as opposed to bash) you can do exactly what you want.
alias print 'lpr \!^ -Pps5'
print memo.txt
The notation \!^
causes the argument to be inserted in the command at this point.
The !
character is preceeded by a \
to prevent it being interpreted as a history command.
You can also pass multiple arguments:
alias print 'lpr \!* -Pps5'
print part1.ps glossary.ps figure.ps
(Examples taken from http://unixhelp.ed.ac.uk/shell/alias_csh2.1.html .)
The 'bug' is discussed here https://bugs.eclipse.org/bugs/show_bug.cgi?id=402983. A lot of discussion around 'multiple monitor' set-ups. I experienced the problem today(click in Eclipse (off-the-shelf ADT v22.3.0-887826) Package Explorer then click in java editor, and the "no more handles" error appears). It makes Eclipse unuseable.
Got me thinking that it is a monitor/graphics card problem on my win7 64bit PC, rather than a problem with Eclipse. I re-installed the graphics card (nVidia GTX480) and updated the drivers. Noticed multiple error dialog boxes(samsung monitor not found) relating to my monitor(in fact a single BX2440 monitor set-up) as i closed the system down for reboot. So, on re-boot I upgraded the monitor driver. Then booted again, and the problem has gone(at least for now).
BTW, I don't have Win 7 SP1 installed, so i don't think the 'full Windows update' solution discussed elsewhere on SO necessarily works for everyone.
For getting all post parameters there is Map which contains request param name as key and param value as key.
Map params = servReq.getParameterMap();
And to get parameters with known name normal
String userId=servReq.getParameter("user_id");
you may use this:
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
