If you are drawing on the Graphics of the Control than you should do something draw on the Bitmap everything you are drawing on the canvas, but have in mind that Bitmap needs to be the exact size of the control you are drawing on:
Bitmap bmp = new Bitmap(myControl.ClientRectangle.Width,myControl.ClientRectangle.Height);
Graphics gBmp = Graphics.FromImage(bmp);
gBmp.DrawEverything(); //this is your code for drawing
gBmp.Dispose();
bmp.Save("image.png", ImageFormat.Png);
Or you can use a DrawToBitmap
method of the Control. Something like this:
Bitmap bmp = new Bitmap(myControl.ClientRectangle.Width, myControl.ClientRectangle.Height);
myControl.DrawToBitmap(bmp,new Rectangle(0,0,bmp.Width,bmp.Height));
bmp.Save("image.png", ImageFormat.Png);
To Move
item in list simply add:
// move item to index 0
Object object = ObjectList.get(index);
ObjectList.remove(index);
ObjectList.add(0,object);
To Swap
two items in list simply add:
// swap item 10 with 20
Collections.swap(ObjectList,10,20);
Suppose you want to use, say ID in any other webpage then you can do it by following code snippet :
String id=(String)session.getAttribute("uid");
Here uid is the attribute in which you have stored the ID earlier. You can set it by:
session.setAttribute("uid",id);
plt.axis('scaled')
works well for me.
Another possibility is to use mobile-detect.js. Try the demo.
<script src="mobile-detect.js"></script>
<script>
var md = new MobileDetect(window.navigator.userAgent);
// ... see below
</script>
var MobileDetect = require('mobile-detect'),
md = new MobileDetect(req.headers['user-agent']);
// ... see below
var md = new MobileDetect(
'Mozilla/5.0 (Linux; U; Android 4.0.3; en-in; SonyEricssonMT11i' +
' Build/4.1.A.0.562) AppleWebKit/534.30 (KHTML, like Gecko)' +
' Version/4.0 Mobile Safari/534.30');
// more typically we would instantiate with 'window.navigator.userAgent'
// as user-agent; this string literal is only for better understanding
console.log( md.mobile() ); // 'Sony'
console.log( md.phone() ); // 'Sony'
console.log( md.tablet() ); // null
console.log( md.userAgent() ); // 'Safari'
console.log( md.os() ); // 'AndroidOS'
console.log( md.is('iPhone') ); // false
console.log( md.is('bot') ); // false
console.log( md.version('Webkit') ); // 534.3
console.log( md.versionStr('Build') ); // '4.1.A.0.562'
console.log( md.match('playstation|xbox') ); // false
It maybe the reason The php mysql api is deprecated. if your using below < PHP5.5 just update in your server to 5.6 and above.
If you can't edit this part of code where your dict was defined you can still order it at any point in any way you want, like this:
from collections import OrderedDict
order_of_keys = ["key1", "key2", "key3", "key4", "key5"]
list_of_tuples = [(key, your_dict[key]) for key in order_of_keys]
your_dict = OrderedDict(list_of_tuples)
Chrome Developer Tools has an Audits tab which can show unused CSS selectors.
Run an audit, then, under Web Page Performance see Remove unused CSS rules
For Chrome Version 52.0.2743.116:
In Chrome's Developer Tools, bring up the 'Search' panel by hitting Ctrl
+Shift
+F
.
Type in the name of the element you're trying to find.
Results for binded elements should appear in the panel and state the file they're located in.
First of all, %d is for a int
So %1.16lld
makes no sense, because %d is an integer
That typedef you do, is also unnecessary, use the type straight ahead, makes a much more readable code.
What you want to use is the type double
, for calculating pi
and then using %f
or %1.16f
.
When you
import App from './App.jsx';
That means it will import whatever you export default
. You can rename App
class inside App.jsx
to whatever you want as long as you export default
it will work but you can only have one export default.
So you only need to export default App
and you don't need to export the rest.
If you still want to export the rest of the components, you will need named export.

I actually hit on this problem a week ago. The issue had to do with not using an updated Eclipse version of the Android SDK plugin with the latest version of the SDK. It was a fun problem overall, but it disappeared as soon as I updated it.
I had even updated the AVD images and no luck. Apparently the old plugin cannot see the new image layout or something. This is for version 22.3 of the SDK.
Most browsers don't fully support the numerical values for font-weight
. Here's a good article about the problem, and even tough it's a little old, it does seem to be correct.
If you need something bolder then you might want to try using a different font that's bolder than your existing one. Naturally, you could probably adjust the font size for a similar effect.
A couple of days ago I found a very nice solution of this problem. Read about it here. In two words Mike created a AsyncTaskManager that mediates ProgressDialog and AsyncTask. It's very easy to use this solution. You just need to include in your project several interfaces and several classes and in your activity write some simple code and nest your new AsyncTask from BaseTask. I also advice you to read comments because there are some useful tips.
According to the Oracle PLSQL language definition, a character literal can contain "any printable character in the character set". https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/02_funds.htm#2876
@Robert Love's answer exhibits a best practice for readable code, but you can also just type in the linefeed character into the code. Here is an example from a Linux terminal using sqlplus
:
SQL> set serveroutput on
SQL> begin
2 dbms_output.put_line( 'hello' || chr(10) || 'world' );
3 end;
4 /
hello
world
PL/SQL procedure successfully completed.
SQL> begin
2 dbms_output.put_line( 'hello
3 world' );
4 end;
5 /
hello
world
PL/SQL procedure successfully completed.
Instead of the CHR( NN ) function you can also use Unicode literal escape sequences like u'\0085'
which I prefer because, well you know we are not living in 1970 anymore. See the equivalent example below:
SQL> begin
2 dbms_output.put_line( 'hello' || u'\000A' || 'world' );
3 end;
4 /
hello
world
PL/SQL procedure successfully completed.
For fair coverage I guess it is worth noting that different operating systems use different characters/character sequences for end of line handling. You've got to have a think about the context in which your program output is going to be viewed or printed, in order to determine whether you are using the right technique.
u'\000D\000A'
u'\000A'
u'\0085'
'<BR>'
'<br />'
I just thought that I'd add that there is a notion of Z-order in Swing, see [java.awt.Component#setComponentZOrder][1]
which affects the positions of a component in its parents component array, which determines the painting order.
Note that you should override javax.swing.JComponent#isOptimizedDrawingEnabled to return false in the parent container to get your overlapping components to repaint correctly, otherwise their repaints will clobber each other. (JComponents assume no overlapping children unless isOptimizedDrawingEnabled returns false)
A Grid is a hardware and software infrastructure that clusters and integrates high-end computers, networks, databases, and scientific instruments from multiple sources to form a virtual supercomputer on which users can work collaboratively within virtual organisations
Grid is Mostly free used by academic research etc.
Clouds are a large pool of easily usable and accessible virtualized resources (such as hardware, development platforms and/or services). These resources can be dynamically reconfigured to adjust to a variable load (scale), allowing also for an optimum resource utilization. This pool of resources is typically exploited by a pay peruse model in which guarantees are offered by the Infrastructure Provider by customized service level agreements.
Cloud is not free. It is a service, provided by different service providers and they charge according to your work done.
You can do it by running with following command.
php -S localhost:8888
If, like me, you found that @wiggin answer didn't work and images still did not appear in-line, you can use the 'align' property of the html image tag and some breaks to achieve the desired effect, for example:
# Title
<img align="left" src="./documentation/images/A.jpg" alt="Made with Angular" title="Angular" hspace="20"/>
<img align="left" src="./documentation/images/B.png" alt="Made with Bootstrap" title="Bootstrap" hspace="20"/>
<img align="left" src="./documentation/images/C.png" alt="Developed using Browsersync" title="Browsersync" hspace="20"/>
<br/><br/><br/><br/><br/>
## Table of Contents...
Obviously, you have to use more breaks depending on how big the images are: awful yes, but it worked for me so I thought I'd share.
You can do it using Serialization
from socket import *
from json import dumps, loads
def recvall(conn):
data = ""
while True:
try:
data = conn.recv(1024)
return json.loads(data)
except ValueError:
continue
def sendall(conn):
conn.sendall(json.dumps(data))
NOTE: If you want to shara a file using code above you need to encode / decode it into base64
Actually it depends on your use case.
1) You want to protect your route from unauthorized users
If that is the case you can use the component called <Redirect />
and can implement the following logic:
import React from 'react'
import { Redirect } from 'react-router-dom'
const ProtectedComponent = () => {
if (authFails)
return <Redirect to='/login' />
}
return <div> My Protected Component </div>
}
Keep in mind that if you want <Redirect />
to work the way you expect, you should place it inside of your component's render method so that it should eventually be considered as a DOM element, otherwise it won't work.
2) You want to redirect after a certain action (let's say after creating an item)
In that case you can use history:
myFunction() {
addSomeStuff(data).then(() => {
this.props.history.push('/path')
}).catch((error) => {
console.log(error)
})
or
myFunction() {
addSomeStuff()
this.props.history.push('/path')
}
In order to have access to history, you can wrap your component with an HOC called withRouter
. When you wrap your component with it, it passes match
location
and history
props. For more detail please have a look at the official documentation for withRouter.
If your component is a child of a <Route />
component, i.e. if it is something like <Route path='/path' component={myComponent} />
, you don't have to wrap your component with withRouter
, because <Route />
passes match
, location
, and history
to its child.
3) Redirect after clicking some element
There are two options here. You can use history.push()
by passing it to an onClick
event:
<div onClick={this.props.history.push('/path')}> some stuff </div>
or you can use a <Link />
component:
<Link to='/path' > some stuff </Link>
I think the rule of thumb with this case is to try to use <Link />
first, I suppose especially because of performance.
For anyone coming across this question who uses Jaspersoft Studio (which, I think, is replacing iReports; it's quite similar, still freeware, just based on eclipse), look for the "Compile Report" icon on top of the editor area of your .jrxml file. Its icon, first in that line of icons, is a file with binary numbers on it (at least in version 5.6.2):
Clicking this icon will generate the .jasper file in the same directory as the .jrxml file.
If you specifically want methods, you should use inspect.ismethod.
For method names:
import inspect
method_names = [attr for attr in dir(self) if inspect.ismethod(getattr(self, attr))]
For the methods themselves:
import inspect
methods = [member for member in [getattr(self, attr) for attr in dir(self)] if inspect.ismethod(member)]
Sometimes inspect.isroutine
can be useful too (for built-ins, C extensions, Cython without the "binding" compiler directive).
Dataframes have a sort_index
method which returns a copy by default. Pass inplace=True
to operate in place.
import pandas as pd
df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df.sort_index(inplace=True)
print(df.to_string())
Gives me:
A
1 4
29 2
100 1
150 5
234 3
Create a tar archive file on the fly and pipe that to md5sum
:
tar c dir | md5sum
This produces a single md5sum that should be unique to your file and sub-directory setup. No files are created on disk.

public static String fromUnicode(String unicode) {
String str = unicode.replace("\\", "");
String[] arr = str.split("u");
StringBuffer text = new StringBuffer();
for (int i = 1; i < arr.length; i++) {
int hexVal = Integer.parseInt(arr[i], 16);
text.append(Character.toChars(hexVal));
}
return text.toString();
}
public static String toUnicode(String text) {
StringBuffer sb = new StringBuffer();
for (int i = 0; i < text.length(); i++) {
int codePoint = text.codePointAt(i);
// Skip over the second char in a surrogate pair
if (codePoint > 0xffff) {
i++;
}
String hex = Integer.toHexString(codePoint);
sb.append("\\u");
for (int j = 0; j < 4 - hex.length(); j++) {
sb.append("0");
}
sb.append(hex);
}
return sb.toString();
}
@Test
public void toUnicode() {
System.out.println(toUnicode(""));
System.out.println(toUnicode(""));

Chart.js has a bug:
Chart.controller(instance)
registers any new chart in a global property Chart.instances[]
and deletes it from this property on .destroy()
.
But at chart creation Chart.js also writes ._meta
property to dataset variable:
var meta = dataset._meta[me.id];
if (!meta) {
meta = dataset._meta[me.id] = {
type: null,
data: [],
dataset: null,
controller: null,
hidden: null, // See isDatasetVisible() comment
xAxisID: null,
yAxisID: null
};
and it doesn't delete this property on destroy()
.
If you use your old dataset object without removing ._meta property
, Chart.js will add new dataset to ._meta
without deletion previous data. Thus, at each chart's re-initialization your dataset object accumulates all previous data.
In order to avoid this, destroy dataset object after calling Chart.destroy()
.
Your first CSS selector—social.h2
—is looking for the "social" element in the "h2", class, e.g.:
<social class="h2">
Class selectors are proceeded with a dot (.
). Also, use a space () to indicate that one element is inside of another. To find an
<h2>
descendant of an element in the social
class, try something like:
.social h2 {
color: pink;
font-size: 14px;
}
To get a better understanding of CSS selectors and how they are used to reference your HTML, I suggest going through the interactive HTML and CSS tutorials from CodeAcademy. I hope that this helps point you in the right direction.
If you put position:relative;
on the outer element, the inner element will place itself according to this one. Then a width:auto;
on the inner element will be the same as the width of the outer.
I am pretty new to all of this, but I found that if the script is started via CScript.exe (console scripting host) there is no window popping up on exec(): so when running:
cscript myscript.vbs //nologo
any .Exec() calls in the myscript.vbs do not open an extra window, meaning that you can use the first variant of your original solution (using exec).
(Note that the two forward slashes in the above code are intentional, see cscript /?)
Why double pointers?
The objective is to change what studentA points to, using a function.
#include <stdio.h>
#include <stdlib.h>
typedef struct Person{
char * name;

*/
void change(Person ** x, Person * y){
*x = y; // since x is a pointer to a pointer, we access its value: a pointer to a Person struct.
}
void dontChange(Person * x, Person * y){
x = y;
}
int main()
{
Person * studentA = (Person *)malloc(sizeof(Person));
studentA->name = "brian";
Person * studentB = (Person *)malloc(sizeof(Person));
studentB->name = "erich";
/**
* we could have done the job as simple as this!
* but we need more work if we want to use a function to do the job!
*/
// studentA = studentB;
printf("1. studentA = %s (not changed)\n", studentA->name);
dontChange(studentA, studentB);
printf("2. studentA = %s (not changed)\n", studentA->name);
change(&studentA, studentB);
printf("3. studentA = %s (changed!)\n", studentA->name);
return 0;
}
/**

Below are the rules if you believe it's random. A utility function can be created on the basis of these rules.
If the value contains a comma, newline or double quote, then the String value should be returned enclosed in double quotes.
Any double quote characters in the value should be escaped with another double quote.
If the value does not contain a comma, newline or double quote, then the String value should be returned unchanged.
If you want to ensure only that class will match then use getClass() ==
. If you want to match subclasses then instanceof
is needed.
Also, instanceof will not match against a null but is safe to compare against a null. So you don't have to null check it.
if ( ! (obj instanceof MyClass) ) { return false; }

If you haven't had to do so already you'll need to add a reference to System.Windows.Forms in the project properties.
Also you'll need to add
Imports System.Windows.Forms
to the file where you're adding the override class.
For OnPaintBackground you'll need to add a reference for System.Drawing then
Imports System.Drawing.Printing.PrintEventArgs
Its work 100% i am Sure.

As a further useful solution for those of you on Windows 7 and above - if you use:
C:\Program Files\Java>mklink /D jdk8 jdk1.8.0_25
you get a Symbolic Link
folder that can be adjusted whenever a new JDK comes out.
All you need to do then is set your
netbeans_jdkhome="C:\Program Files\Java\jdk8"
(in both locations for Netbeans 8) and you never have to edit the config again. Just tweak the symlink each time your JDK is updated.
If you are using Webpack 4, the answer is to use the ProvidePlugin
. Their documentation specifically covers angular.js with jquery use case:
new webpack.ProvidePlugin({
'window.jQuery': 'jquery'
});
The issue is that when using import
syntax angular.js and jquery will always be imported before you have a chance to assign jquery to window.jQuery (import
statements will always run first no matter where they are in the code!). This means that angular will always see window.jQuery as undefined until you use ProvidePlugin
.
you can try
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader("<root><node1></node1></root>"));
Document doc = db.parse(is);

Follow up to accepted answer.
You need something other than CTRL-D to designate the end if using this in a script. Try this instead:
cat << EOF >> filename
This is text entered via the keyboard or via a script.
EOF
This will append text to the stated file (not including "EOF").
It utilizes a here document (or heredoc).
However if you need sudo to append to the stated file, you will run into trouble utilizing a heredoc due to I/O redirection if you're typing directly on the command line.
This variation will work when you are typing directly on the command line:
sudo sh -c 'cat << EOF >> filename
This is text entered via the keyboard.
EOF'
Or you can use tee
instead to avoid the command line sudo issue seen when using the heredoc with cat:
tee -a filename << EOF
This is text entered via the keyboard or via a script.
EOF
The Path
objects in path library offer both a context manager and a chdir
method for this purpose:
from path import Path

...
Path("somewhere").chdir()
Strictly speaking, if you only want to print "Blah" here is the solution :
find . -maxdepth 1 -name 'xorg-x11-fonts*' -printf 'BLAH' -quit
Here is another way :
doesFirstFileExist(){
test -e "$1"
}
if doesFirstFileExist xorg-x11-fonts*
then printf "BLAH"
fi
But I think the most optimal is as follow, because it won't try to sort file names :
if [ -z `find . -maxdepth 1 -name 'xorg-x11-fonts*' -printf 1 -quit` ]
then printf "BLAH"
fi
For me the dialogue appears more than one if I click the dpFlightDate edit text more than one time same for the timmer dialog . how can I avoid this dialog to appear only once and if the user click's 2nd time the dialog must not appear again ie if dialog is on the screen ?
// perform click event on edit text
dpFlightDate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// calender class's instance and get current date , month and year from calender
final Calendar c = Calendar.getInstance();
int mYear = c.get(Calendar.YEAR); // current year
int mMonth = c.get(Calendar.MONTH); // current month
int mDay = c.get(Calendar.DAY_OF_MONTH); // current day
// date picker dialog
datePickerDialog = new DatePickerDialog(frmFlightDetails.this,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
// set day of month , month and year value in the edit text
dpFlightDate.setText(dayOfMonth + "/"
+ (monthOfYear + 1) + "/" + year);
}
}, mYear, mMonth, mDay);
datePickerDialog.show();
}
});
tpFlightTime.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Use the current time as the default values for the picker
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
// Create a new instance of TimePickerDialog
timePickerDialog = new TimePickerDialog(frmFlightDetails.this, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
tpFlightTime.setText( selectedHour + ":" + selectedMinute);
}
}, hour, minute, true);//Yes 24 hour time
timePickerDialog.setTitle("Select Time");
timePickerDialog.show();
}
});
Here is the simplest command for it
mysql -h<hostname> -u<username> -p<password> -e 'select * from databaseName.tableNaame' | sed 's/\t/,/g' > output.csv
If there is a comma in the column value then we can generate .tsv instead of .csv with the following command
mysql -h<hostname> -u<username> -p<password> -e 'select * from databaseName.tableNaame' > output.csv
you can do like that
import smtplib
from email.mime.text import MIMEText
from email.header import Header
server = smtplib.SMTP('mail.servername.com', 25)
server.ehlo()
server.starttls()
server.login('username', 'password')
from = '[email protected]'
to = '[email protected]'
body = 'That A Message For My Girl Friend For tell Him If We will go to eat Something This Nigth'
subject = 'Invite to A Diner'
msg = MIMEText(body,'plain','utf-8')
msg['Subject'] = Header(subject, 'utf-8')
msg['From'] = Header(from, 'utf-8')
msg['To'] = Header(to, 'utf-8')
message = msg.as_string()
server.sendmail(from, to, message)
I had that problem before. I just solved it by expanding the tomcat tree and delete the folder that is causing the clash. in your case is /FirstApache
. after you delete it. then you rerun it, you should be able to run. If it happens again, delete it and try again.
Use JSON.stringify()
and JSON.parse()
as suggested by no! This prevents the maybe rare but possible problem of a member name which includes the delimiter (e.g. member name three|||bars
).
Find out the process ID (PID) which is occupying the port number (e.g., 5955) you would like to free
sudo lsof -i :5955
Kill the process which is currently using the port using its PID
sudo kill -9 PID
I used this in a style sheet for three columns separated by vertical borders and it worked fine:
#column-left {
border-left: 1px solid #dddddd;
}
#column-center {
/*no border needed/*
}
#column-right {
border-right: 1px solid #dddddd;
}
The column on the left gets a border on the right, the column on the right gets a border on the left and the the middle column is already taken care of by the left and right.
If your columns are inside a div/wrapper/table/etc... don't forget to add extra space to accomodate the width of the borders.
$localIP = gethostbyname(trim(exec("hostname")));
I tried in Windows pc and Its worked and also think that Will work on Linux to.
Use the continue statement:
foreach(object number in mycollection) {
if( number < 0 ) {
continue;
}
}
<div id="idVal">
<!--div content goes here-->
</div>
...
<script type="text/javascript">
$(document).ready(function(){
var divLoc = $('#idVal').offset();
$('html, body').animate({scrollTop: divLoc.top}, "slow");
});
</script>
This example shows to locate to a particular div id i.e, 'idVal' in this case. If you have subsequent divs/tables that will open up in this page via ajax, then you can assign unique divs and call the script to scroll to the particular location for each contents of divs.
Hope this will be useful.
If you open the DMP file with an editor that can handle big files, you might be able to locate the areas where the schema names are mentioned. Just be sure not to change anything. It would be better if you opened a copy of the original dump.
If you have your drawable set to the ImageView you can do it with a 1 liner:

Here is my way to solve this problem at ubuntu 12.04:
sudo apt-get install build-essential libncursesw5-dev libssl-dev libgdbm-dev libc6-dev libsqlite3-dev tk-dev
Then install the python3 from source code:
wget https://www.python.org/ftp/python/3.4.0/Python-3.4.0.tar.xz
tar xvf Python-3.4.0.tar.xz
cd Python-3.4.0
./configure
make
make test
sudo make install
When you finished installing all of them, pip3 will get installed automatically.
That's works for me accurately
let template = null;

});
d = {} is an empty object right now.
And d[a] is also an empty object.
It does not have any key values. So you should initialize the key values to this.
d[a] = {

}
It may have been because I am still new to VS and definitely new to C, but the only thing that allowed me to build was adding
#pragma warning(disable:4996)
At the top of my file, this suppressed the C4996 error I was getting with sprintf
A bit annoying but perfect for my tiny bit of code and by far the easiest.

Another option that doesn't require subclassing - leave placeholder blank, and put a label on top of edit button. Manage the label just like you would manage the placeholder (clearing once user inputs anything..)

%0|%0
is a fork bomb. It will spawn another process using a pipe |
which runs a copy of the same program asynchronously. This hogs the CPU and memory, slowing down the system to a near-halt (or even crash the system).
%0
refers to the command used to run the current program. For example, script.bat
A pipe |
symbol will make the output or result of the first command sequence as the input for the second command sequence. In the case of a fork bomb, there is no output, so it will simply run the second command sequence without any input.
Expanding the example, %0|%0
could mean script.bat|script.bat
. This runs itself again, but also creating another process to run the same program again (with no input).

The USAGE-privilege in mysql simply means that there are no privileges for the user 'phpadmin'@'localhost' defined on global level *.*
. Additionally the same user has ALL-privilege on database phpmyadmin phpadmin.*
.
So if you want to remove all the privileges and start totally from scratch do the following:
Revoke all privileges on database level:
REVOKE ALL PRIVILEGES ON phpmyadmin.* FROM 'phpmyadmin'@'localhost';
Drop the user 'phpmyadmin'@'localhost'
DROP USER 'phpmyadmin'@'localhost';
Above procedure will entirely remove the user from your instance, this means you can recreate him from scratch.
To give you a bit background on what described above: as soon as you create a user the mysql.user
table will be populated. If you look on a record in it, you will see the user and all privileges set to 'N'
. If you do a show grants for 'phpmyadmin'@'localhost';
you will see, the allready familliar, output above. Simply translated to "no privileges on global level for the user". Now your grant ALL
to this user on database level, this will be stored in the table mysql.db
. If you do a SELECT * FROM mysql.db WHERE db = 'nameofdb';
you will see a 'Y'
on every priv.
Above described shows the scenario you have on your db at the present. So having a user that only has USAGE
privilege means, that this user can connect, but besides of SHOW GLOBAL VARIABLES; SHOW GLOBAL STATUS;
he has no other privileges.

What you want is maxlength
.
Valid for
text
,search
,url
,tel
,password
, it defines the maximum number of characters (as UTF-16 code units) the user can enter into the field. This must be an integer value 0 or higher. If no maxlength is specified, or an invalid value is specified, the field has no maximum length. This value must also be greater than or equal to the value of minlength.
You might consider using one of these input
types.
I know this is an old one but it comes up top of Google and all the links provided now seem out of date.
This is the latest list of types Facebook accepts: https://developers.facebook.com/docs/reference/opengraph
If you don't use one of these then the type will default to 'website' which is best used for home pages/summarising a web site.
In answer to the OP you would now want to use a place which will allow you to add lat/long location details.

Geocoding through Javascript

As an alternative to rendering a raster image, you can embed a SVG file:
<a><img src="http://dump.thecybershadow.net/6c736bfd11ded8cdc5e2bda009a6694a/colortext.svg"/></a>
You can then add color text to the SVG file as usual:
<?xml version="1.0" encoding="utf-8"?>
<svg version="1.1"
xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
width="100" height="50"
>
<text font-size="16" x="10" y="20">
<tspan fill="red">Hello</tspan>,
<tspan fill="green">world</tspan>!
</text>
</svg>
Unfortunately, even though you can select and copy text when you open the .svg
file, the text is not selectable when the SVG image is embedded.

SQL Case Sensitive String Compare
These examples may be helpful:
Declare @S1 varchar(20) = 'SQL'
Declare @S2 varchar(20) = 'sql'
if @S1 = @S2 print 'equal!' else print 'NOT equal!' -- equal (default non-case sensitivity for SQL
if cast(@S1 as binary) = cast(Upper(@S2) as binary) print 'equal!' else print 'NOT equal!' -- equal
if cast(@S1 as binary) = cast(@S2 as binary) print 'equal!' else print 'NOT equal!' -- not equal
if @S1 COLLATE Latin1_General_CS_AS = Upper(@S2) COLLATE Latin1_General_CS_AS print 'equal!' else print 'NOT equal!' -- equal
if @S1 COLLATE Latin1_General_CS_AS = @S2 COLLATE Latin1_General_CS_AS print 'equal!' else print 'NOT equal!' -- not equal
The convert is probably more efficient than something like runtime calculation of hashbytes, and I'd expect the collate may be even faster.
Return data as XML
SELECT CONVERT(XML, [Data]) AS [Value]
FROM [dbo].[FormData]
WHERE [UID] LIKE '{my-uid}'
Make sure you set a reasonable limit in the SSMS options window, depending on the result you're expecting.
This will work if the text you're returning doesn't contain unencoded characters like &
instead of &
that will cause the XML conversion to fail.
Returning data using PowerShell
For this you will need the PowerShell SQL Server module installed on the machine on which you'll be running the command.
If you're all set up, configure and run the following script:
Invoke-Sqlcmd -Query "SELECT [Data] FROM [dbo].[FormData] WHERE [UID] LIKE '{my-uid}'" -ServerInstance "database-server-name" -Database "database-name" -Username "user" -Password "password" -MaxCharLength 10000000 | Out-File -filePath "C:\db_data.txt"
Make sure you set the -MaxCharLength
parameter to a value that suits your needs.
You should give an object as argument
userModel.count({name: "sam"});
or
userModel.count({name: "sam"}).exec(); //if you are using promise
or
userModel.count({}); // if you want to get all counts irrespective of the fields
On the recent version of mongoose, count() is deprecated so use
userModel.countDocuments({name: "sam"});
As of CMake 3.1+ the developers strongly discourage users from using file(GLOB
or file(GLOB_RECURSE
to collect lists of source files.
Note: We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate. The CONFIGURE_DEPENDS flag may not work reliably on all generators, or if a new generator is added in the future that cannot support it, projects using it will be stuck. Even if CONFIGURE_DEPENDS works reliably, there is still a cost to perform the check on every rebuild.
See the documentation here.
There are two goods answers ([1], [2]) here on SO detailing the reasons to manually list source files.
It is possible. E.g. with file(GLOB
:
cmake_minimum_required(VERSION 2.8)
file(GLOB helloworld_SRC
"*.h"
"*.cpp"
)
add_executable(helloworld ${helloworld_SRC})
Note that this requires manual re-running of cmake
if a source file is added or removed, since the generated build system does not know when to ask CMake to regenerate, and doing it at every build would increase the build time.
As of CMake 3.12, you can pass the CONFIGURE_DEPENDS
flag to file(GLOB
to automatically check and reset the file lists any time the build is invoked. You would write:
cmake_minimum_required(VERSION 3.12)
file(GLOB helloworld_SRC CONFIGURE_DEPENDS "*.h" "*.cpp")
This at least lets you avoid manually re-running CMake every time a file is added.
I just discovered PixieDebugger. Even thought I have not yet had the time to test it, it really seems the most similar way to debug the way we're used in ipython with ipdb
It also has an "evaluate" tab
Close all instances of the arduino IDE open ~/.arduino/preferences.txt and look for the line:
serial.port=<not your port>
and change it to your port:
serial.port=/dev/ttyACM0

When working to create Cross Browser Favicons (including touch icons) there are several things to consider.
The first (of course) is Internet Explorer. IE does not support PNG favicons until version 11. So our first line is a conditional comment for favicons in IE 9 and below:
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->
To cover the uses of the icon create it at 32x32 pixels. Notice the rel="shortcut icon"
for IE to recognize the icon it needs the word shortcut
which is not standard. Also we wrap the .ico
favicon in a IE conditional comment because Chrome and Safari will use the .ico
file if it is present, despite other options available, not what we would like.
The above covers IE up to IE 9. IE 11 accepts PNG favicons, however, IE 10 does not. Also IE 10 does not read conditional comments thus IE 10 won't show a favicon. With IE 11 and Edge available I don't see IE 10 in widespread use, so I ignore this browser.
For the rest of the browsers we are going to use the standard way to cite a favicon:
<link rel="icon" href="path/to/favicon.png">
This icon should be 196x196 pixels in size to cover all devices that may use this icon.
To cover touch icons on mobile devices we are going to use Apple's proprietary way to cite a touch icon:
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">
Using rel="apple-touch-icon-precomposed"
will not apply the reflective shine when bookmarked on iOS. To have iOS apply the shine use rel="apple-touch-icon"
. This icon should be sized to 180x180 pixels as that is the current size recommend by Apple for the latest iPhones and iPads. I have read Blackberry will also use rel="apple-touch-icon-precomposed"
.
As a note: Chrome for Android states:
The apple-touch-* are deprecated, and will be supported only for a short time. (Written as of beta for m31 of Chrome).
Custom Tiles for IE 11+ on Windows 8.1+
IE 11+ on Windows 8.1+ does offer a way to create pinned tiles for your site.
Microsoft recommends creating a few tiles at the following size:
Small: 128 x 128
Medium: 270 x 270
Wide: 558 x 270
Large: 558 x 558
These should be transparent images as we will define a color background next.
Once these images are created you should create an xml file called browserconfig.xml
with the following code:
<?xml version="1.0" encoding="utf-8"?>
<browserconfig>
<msapplication>
<tile>
<square70x70logo src="images/smalltile.png"/>
<square150x150logo src="images/mediumtile.png"/>
<wide310x150logo src="images/widetile.png"/>
<square310x310logo src="images/largetile.png"/>
<TileColor>#009900</TileColor>
</tile>
</msapplication>
</browserconfig>
Save this xml file in the root of your site. When a site is pinned IE will look for this file. If you want to name the xml file something different or have it in a different location add this meta tag to the head
:
<meta name="msapplication-config" content="path-to-browserconfig/custom-name.xml" />
For additional information on IE 11+ custom tiles and using the XML file visit Microsoft's website.
Putting it all together:
To put it all together the above code would look like this:
<!-- For IE 9 and below. ICO should be 32x32 pixels in size -->
<!--[if IE]><link rel="shortcut icon" href="path/to/favicon.ico"><![endif]-->
<!-- Touch Icons - iOS and Android 2.1+ 180x180 pixels in size. -->
<link rel="apple-touch-icon-precomposed" href="apple-touch-icon-precomposed.png">
<!-- Firefox, Chrome, Safari, IE 11+ and Opera. 196x196 pixels in size. -->
<link rel="icon" href="path/to/favicon.png">
Windows Phone Live Tiles
If a user is using a Windows Phone they can pin a website to the start screen of their phone. Unfortunately, when they do this it displays a screenshot of your phone, not a favicon (not even the MS specific code referenced above). To make a "Live Tile" for Windows Phone Users for your website one must use the following code:
Here are detailed instructions from Microsoft but here is a synopsis:
Step 1
Create a square image for your website, to support hi-res screens create it at 768x768 pixels in size.
Step 2
Add a hidden overlay of this image. Here is example code from Microsoft:
<div id="TileOverlay" onclick="ToggleTileOverlay()" style='background-color: Highlight; height: 100%; width: 100%; top: 0px; left: 0px; position: fixed; color: black; visibility: hidden'>
<img src="customtile.png" width="320" height="320" />
<div style='margin-top: 40px'>
Add text/graphic asking user to pin to start using the menu...
</div>
</div>
Step 3
You then can add thew following line to add a pin to start link:
<a href="javascript:ToggleTileOverlay()">Pin this site to your start screen</a>
Microsoft recommends that you detect windows phone and only show that link to those users since it won't work for other users.
Step 4
Next you add some JS to toggle the overlay visibility
<script>
function ToggleTileOverlay() {
var newVisibility = (document.getElementById('TileOverlay').style.visibility == 'visible') ? 'hidden' : 'visible';
document.getElementById('TileOverlay').style.visibility = newVisibility;
}
</script>
Note on Sizes
I am using one size as every browser will scale down the image as necessary. I could add more HTML to specify multiple sizes if desired for those with a lower bandwidth but I am already compressing the PNG files heavily using TinyPNG and I find this unnecessary for my purposes. Also, according to philippe_b's answer Chrome and Firefox have bugs that cause the browser to load all sizes of icons. Using one large icon may be better than multiple smaller ones because of this.

Alternatively you can also use CASE
for the same:
SELECT CASE WHEN field1 IS NULL OR field1 = ''
THEN 'empty'
ELSE field1 END AS field1
FROM tablename.
Set content-type and other headers before you write the file out. For small files the content is buffered, and the browser gets the headers first. For big ones the data come first.

Also there is
aRange.EntireColumn.AutoFit();
See What is the difference between Range.Columns and Range.EntireColumn.
There are two ways to use this variable:
passing it as a command line argument just like Job mentioned:
cmake -DCMAKE_INSTALL_PREFIX=< install_path > ..
assigning value to it in CMakeLists.txt
:
SET(CMAKE_INSTALL_PREFIX < install_path >)
But do remember to place it BEFORE PROJECT(< project_name>)
command, otherwise it will not work!
You have one DateFormat
, but you need two: one for the input, and another for the output.
You've got one for the output, but I don't see anything that would match your input. When you give the input string to the output format, it's no surprise that you see that exception.
DateFormat inputDateFormat = new SimpleDateFormat("yyyy-MM-ddhh:mm:ss.SSS-Z");
Here's how to do it using default ACLs, at least under Linux.
First, you might need to enable ACL support on your filesystem. If you are using ext4 then it is already enabled. Other filesystems (e.g., ext3) need to be mounted with the acl
option. In that case, add the option to your /etc/fstab
. For example, if the directory is located on your root filesystem:
/dev/mapper/qz-root / ext3 errors=remount-ro,acl 0 1
Then remount it:
mount -oremount /
Now, use the following command to set the default ACL:
setfacl -dm u::rwx,g::rwx,o::r /shared/directory
All new files in /shared/directory
should now get the desired permissions. Of course, it also depends on the application creating the file. For example, most files won't be executable by anyone from the start (depending on the mode argument to the open(2) or creat(2) call), just like when using umask. Some utilities like cp
, tar
, and rsync
will try to preserve the permissions of the source file(s) which will mask out your default ACL if the source file was not group-writable.
Hope this helps!
When accessing the field value, pass the instance rather than null.
Why not use code generation here? Eclipse, for example, will generate a reasoble toString implementation for you.
Below code with Redirected "while-read" loop works fine for me
while read LINE
do
let count++
echo "$count $LINE"
done < $FILENAME
echo -e "\nTotal $count Lines read"
As for the question which event you should use for this: use the input
event, and fall back to keyup
/keydown
in older browsers.
Here’s an example, DOM0-style:
someElement.oninput = function() {
this.onkeydown = null;
// Your code goes here
};
someElement.onkeydown = function() {
// Your code goes here
};
The other question is how to count the number of characters in the string. Depending on your definition of “character”, all answers posted so far are incorrect. The string.length
answer is only reliable when you’re certain that only BMP Unicode symbols will be entered. For example, 'a'.length == 1
, as you’d expect.
However, for supplementary (non-BMP) symbols, things are a bit different. For example, ''.length == 2
, even though there’s only one Unicode symbol there. This is because JavaScript exposes UCS-2 code units as “characters”.
Luckily, it’s still possible to count the number of Unicode symbols in a JavaScript string through some hackery. You could use Punycode.js’s utility functions to convert between UCS-2 strings and Unicode code points for this:
// `String.length` replacement that only counts full Unicode characters
punycode.ucs2.decode('a').length; // 1
punycode.ucs2.decode('').length; // 1 (note that `''.length == 2`!)
P.S. I just noticed the counter script that Stack Overflow uses gets this wrong. Try entering , and you’ll see that it (incorrectly) counts as two characters.
You can use this example and change it's implementation like this:
[self enumerateAttribute:NSParagraphStyleAttributeName
inRange:NSMakeRange(0, self.length)
options:0
usingBlock:^(id _Nullable value, NSRange range, BOOL * _Nonnull stop) {
NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
//add your specific settings for paragraph
//...
//...
[self removeAttribute:NSParagraphStyleAttributeName range:range];
[self addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:range];
}];

:
x=$(awk '/MemTotal/ {print $2}' /proc/meminfo)
echo $((x/1024))
or:
x=$(awk '/MemTotal/ {print $2}' /proc/meminfo) ; echo $((x/1024))
It is similar to a question called letter combinations of a phone number,
here is my solution.
It works for an arbitrary number of digits, so long as the result doesn't exceed the memory limit.
import java.util.HashMap;
public class Solution {
public ArrayList<String> letterCombinations(String digits) {
ArrayList<String> res = new ArrayList<String>();
ArrayList<String> preres = new ArrayList<String>();
res.add("");
for(int i = 0; i < digits.length(); i++) {
String letters = map.get(digits.charAt(i));
if (letters.length() == 0)
continue;
for(String str : res) {
for(int j = 0; j < letters.length(); j++)
preres.add(str + letters.charAt(j));
}
res = preres;
preres = new ArrayList<String>();
}
return res;
}
static final HashMap<Character,String> map = new HashMap<Character,String>(){{
put('1', "");
put('2',"abc");
put('3',"def");
put('4',"ghi");
put('5',"jkl");
put('6',"mno");
put('7',"pqrs");
put('8',"tuv");
put('9',"wxyz");
put('0', "");
}} ;
}
I'm not sure how 12-digit international numbers affect the design.
Edit: International numbers will also be handled
Full days between end of month and start of today, including the last day of the month:
SELECT LAST_DAY (TRUNC(SysDate)) - TRUNC(SysDate) + 1 FROM dual
Days between using exact time:
SELECT SysDate - TO_DATE('2018-01-01','YYYY-MM-DD') FROM dual
One thing that to be remembered while solving such problems is that in JSON file, a {
indicates a JSONObject
and a [
indicates JSONArray
. If one could manage them properly, it would be very easy to accomplish the task of parsing the JSON file. The above code was really very helpful for me and I hope this content adds some meaning to the above code.
The Gson JsonReader documentation explains how to handle parsing of JsonObjects
and JsonArrays
:
- Within array handling methods, first call beginArray() to consume the array's opening bracket. Then create a while loop that accumulates values, terminating when hasNext() is false. Finally, read the array's closing bracket by calling endArray().
- Within object handling methods, first call beginObject() to consume the object's opening brace. Then create a while loop that assigns values to local variables based on their name. This loop should terminate when hasNext() is false. Finally, read the object's closing brace by calling endObject().
As Rob mentioned, you probably just want to print the float to 1 decimal place. In this case, you can do something like the following:
#include <stdio.h>
#include <stdlib.h>
int main()
{
float conver = 45.592346543;
printf("conver is %0.1f\n",conver);
return 0;
}
If you want to actually round the stored value, that's a little more complicated. For one, your one-decimal-place representation will rarely have an exact analog in floating-point. If you just want to get as close as possible, something like this might do the trick:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main()
{
float conver = 45.592346543;
printf("conver is %0.1f\n",conver);
conver = conver*10.0f;
conver = (conver > (floor(conver)+0.5f)) ? ceil(conver) : floor(conver);
conver = conver/10.0f;
//If you're using C99 or better, rather than ANSI C/C89/C90, the following will also work.
//conver = roundf(conver*10.0f)/10.0f;
printf("conver is now %f\n",conver);
return 0;
}
I doubt this second example is what you're looking for, but I included it for completeness. If you do require representing your numbers in this way internally, and not just on output, consider using a fixed-point representation instead.
If you want to rule out any problems with the else
part, try removing the else
and place the command on a new line. Like this:
IF EXIST D:\RPS_BACKUP\backups_temp\ goto tempexists
goto tempexistscontinue
Assuming a list like below - and assuming some of the options were selected ... (this is a multi select, but this will also work on a single select.
<select multiple='multiple' id='selectListName'>
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
</select>
In some function called based on some event, the following code would clear all selected options.
$("#selectListName").prop('selectedIndex', -1);
There are two types of JAR files available in Java:
Runnable/Executable jar file which contains manifest file.
To run a Runnable jar you can use java -jar fileName.jar
or java -jar -classpath abc.jar fileName.jar
Simple jar file that does not contain a manifest file so you simply run your main class by giving its path java -cp ./fileName.jar MainClass
PFA screenshot of my .gitconfig file
with the below aliases
[alias]
cb = checkout branch
pullb = pull main branch
You can also try BootFlat, which has a section in their documentation specifically for crafting Timelines:
git push origin amd_qlp_tester
will work for you. If you just type git push
, then the remote of the current branch is the default value.
Syntax of push looks like this - git push <remote> <branch>
. If you look at your remote in .git/config
file, you will see an entry [remote "origin"]
which specifies url of the repository. So, in the first part of command you will tell Git where to find repository for this project, and then you just specify a branch.
I had the same error today but I tried something and surprisingly it worked. In the site packages folder there will be a file named wx.pth. Open it using notepad and its contents would be like "wx-2.8-msw-unicode"
It is basically the name of the folder containing wxpython
. Delete this using Ctrl + A and copy the name of the folder from the site packages and paste it here even if it is the same.
Sounds weird but maybe the original file contained a hidden character...
'sender' is called object which has some action perform on some control
'event' its having some information about control which has some behavoiur and identity perform by some user.when action will generate by occuring for event add it keep within array is called event agrs
You can download image by Asyn task
use this class:
public class ImageDownloaderTask extends AsyncTask<String, Void, Bitmap> {
private final WeakReference<ImageView> imageViewReference;
private final MemoryCache memoryCache;
private final BrandItem brandCatogiriesItem;
private Context context;
private String url;
public ImageDownloaderTask(ImageView imageView, String url, Context context) {
imageViewReference = new WeakReference<ImageView>(imageView);
memoryCache = new MemoryCache();
brandCatogiriesItem = new BrandItem();
this.url = url;
this.context = context;
}
@Override
protected Bitmap doInBackground(String... params) {
return downloadBitmap(params[0]);
}
@Override
protected void onPostExecute(Bitmap bitmap) {
if (isCancelled()) {
bitmap = null;
}
if (imageViewReference != null) {
ImageView imageView = imageViewReference.get();
if (imageView != null) {
if (bitmap != null) {
memoryCache.put("1", bitmap);
brandCatogiriesItem.setUrl(url);
brandCatogiriesItem.setThumb(bitmap);
// BrandCatogiriesItem.saveLocalBrandOrCatogiries(context, brandCatogiriesItem);
imageView.setImageBitmap(bitmap);
} else {
Drawable placeholder = imageView.getContext().getResources().getDrawable(R.drawable.placeholder);
imageView.setImageDrawable(placeholder);
}
}
}
}
private Bitmap downloadBitmap(String url) {
HttpURLConnection urlConnection = null;
try {
URL uri = new URL(url);
urlConnection = (HttpURLConnection) uri.openConnection();
int statusCode = urlConnection.getResponseCode();
if (statusCode != HttpStatus.SC_OK) {
return null;
}
InputStream inputStream = urlConnection.getInputStream();
if (inputStream != null) {
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
return bitmap;
}
} catch (Exception e) {
Log.d("URLCONNECTIONERROR", e.toString());
if (urlConnection != null) {
urlConnection.disconnect();
}
Log.w("ImageDownloader", "Error downloading image from " + url);
} finally {
if (urlConnection != null) {
urlConnection.disconnect();
}
}
return null;
}
}
And call this like:
new ImageDownloaderTask(thumbImage, item.thumbnail, context).execute(item.thumbnail);
The below solution is more straight-forward. All you have to do is define one simple function that can "CREATE" the object from the two given items. Then simply apply this function to TWO arrays having elements for which you want to create object and save in resultArray.
var arr1 = ['01','02','03'];
var arr2 = ['item-1','item-2','item-3'];
resultArray = [];
for (var j=0; j<arr1.length; j++) {
resultArray[j] = new makeArray(arr1[j], arr2[j]);
}
function makeArray(first,second) {
this.first = first;
this.second = second;
}
I have a solution which works well but instead an ellipsis it uses a gradient. It works when you have dynamic text so you don't know if it will be long enough to need an ellipse. The advantages are that you don't have to do any JavaScript calculations and it works for variable width containers including table cells and is cross-browser. It uses a couple of extra divs, but it's very easy to implement.

an inline solution combines Groot and Ivaylo suggestions in the format below:
onchange="(function(el){el.value=parseFloat(el.value).toFixed(2);})(this)"
Here is a solution using traditional graphics (and Dirk's data):
> DF <- data.frame(x=1:10, y=rnorm(10)+5, z=sample(letters[1:3], 10, replace=TRUE))
> DF
x y z
1 1 6.628380 c
2 2 6.403279 b
3 3 6.708716 a
4 4 7.011677 c
5 5 6.363794 a
6 6 5.912945 b
7 7 2.996335 a
8 8 5.242786 c
9 9 4.455582 c
10 10 4.362427 a
> attach(DF); plot(x, y, col=c("red","blue","green")[z]); detach(DF)
This relies on the fact that DF$z
is a factor, so when subsetting by it, its values will be treated as integers. So the elements of the color vector will vary with z
as follows:
> c("red","blue","green")[DF$z]
[1] "green" "blue" "red" "green" "red" "blue" "red" "green" "green" "red"
You can add a legend using the legend
function:
legend(x="topright", legend = levels(DF$z), col=c("red","blue","green"), pch=1)
As mentioned both select.select()
and socket.settimeout()
will work.
Note you might need to call settimeout
twice for your needs, e.g.
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(("",0))
sock.listen(1)
# accept can throw socket.timeout
sock.settimeout(5.0)
conn, addr = sock.accept()
# recv can throw socket.timeout
conn.settimeout(5.0)
conn.recv(1024)
Install Inkscape and call it as command line:
${INKSCAPE_PATH} -z -f ${source_svg} -w ${width} -j -e ${dest_png}
You can also snap specific rectangular area only using parameter -j
, e.g. co-ordinate "0:125:451:217"
${INKSCAPE_PATH} -z -f ${source_svg} -w ${width} -j -a ${coordinates} -e ${dest_png}
If you want to show only one object in the SVG file, you can specify the parameter -i
with the object id that you have setup in the SVG. It hides everything else.
${INKSCAPE_PATH} -z -f ${source_svg} -w ${width} -i ${object} -j -a ${coordinates} -e ${dest_png}

Keep in mind that this doesn't do any error-checking while decoding - non base 64 encoded data will get processed.
To print your context ,you can write code like this :
FILE *fp;
char *of;
sprintf(of,"%s%s",text1,text2);
fp=fopen(of,'w');
fprintf(fp,"your print line");
I agree the best is Batarang with it's $scope
after selecting an object (it's the same as angular.element($0).scope()
or even shorter with jQuery: $($0).scope()
(my favorite))
Also, if like me you have you main scope on the body
element, a $('body').scope()
works fine.
How about this?
List<string> monValues = Application["mondayValues"] as List<string>;
int sum = monValues.ConvertAll(Convert.ToInt32).Sum();
You can use something like this:
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class testHashes {
public static void main(String args[]){
Map<String,String> myMap1 = new HashMap<String, String>();
List<Map<String , String>> myMap = new ArrayList<Map<String,String>>();
myMap1.put("URL", "Val0");
myMap1.put("CRC", "Vla1");
myMap1.put("SIZE", "Val2");
myMap1.put("PROGRESS", "Val3");
myMap.add(0,myMap1);
myMap.add(1,myMap1);
for (Map<String, String> map : myMap) {
System.out.println(map.get("URL"));
System.out.println(map.get("CRC"));
System.out.println(map.get("SIZE"));
System.out.println(map.get("PROGRESS"));
}
//System.out.println(myMap);
}
}
i was also getting the same Error, if you are using TortoiseSVN-1.9.5 just do two step Process 1:Click on TSVN.exe tool and 2:Select there on Second Window the Command line for Save on Local Drive with giving the path 3:Click ok Now Restart You Android Studio/IntelliJ
I think what you are looking for is
Request.QueryString["QueryStringName"]
and you can access it on views by adding @
now look at my example,,, I generated a Url with QueryString
var listURL = '@Url.RouteUrl(new { controller = "Sector", action = "List" , name = Request.QueryString["name"]})';
the listURL value is /Sector/List?name=value'
and when queryString
is empty
listURL value is /Sector/List
I encountered this issue because I used setState
instead of state
in the constructor.
EXAMPLE
Change the following incorrect code
constructor(props) {
super(props);
this.setState({
key: ''
});
}
to
constructor(props) {
super(props);
this.state = {
key: ''
};
}
data
will return you a string representation of a list, but it is actually still a string. Just check the type of data
with type(data)
. That means if you try using indexing on this string representation of a list as such data['fruits'][0]
, it will return you "[" as it is the first character of data['fruits']
You can do json.loads(data['fruits'])
to convert it back to a Python list so that you can interact with regular list indexing. There are 2 other ways you can convert it back to a Python list suggested here

Here is how this particular deadlock problem actually occurred and how it was actually resolved. This is a fairly active database with 130K transactions occurring daily. The indexes in the tables in this database were originally clustered. The client requested us to make the indexes nonclustered. As soon as we did, the deadlocking began. When we reestablished the indexes as clustered, the deadlocking stopped.
To summarize the below posts a bit:
If all you care about is if at least one matching row is in the DB then use exists
as it is the most efficient way of checking this: it will return true as soon as it finds at least one matching row whereas count
, etc will find all matching rows.
If you actually need to use the data for processing or if the query has side effects, or if you need to know the actual total number of rows then checking the ROWCOUNT
or count
is probably the best way on hand.
there is a function called isNaN
it return true if it's (Not-a-number) , so u can check for a number this way
if(!isNaN(miscCharge))
{
//do some thing if it's a number
}else{
//do some thing if it's NOT a number
}
hope it works
The simplest make file can be
all : test
test : test.o
gcc -o test test.o
test.o : test.c
gcc -c test.c
clean :
rm test *.o
Exclusive ranges do have some benefits:
For one thing each item in range(0,n)
is a valid index for lists of length n
.
Also range(0,n)
has a length of n
, not n+1
which an inclusive range would.
I'm using:
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
class Program
{
static void Main(string[] args)
{
const string DEFAULT_NAMESPACE = "http://www.something.org/schema";
var serializer = new XmlSerializer(typeof(Person), DEFAULT_NAMESPACE);
var namespaces = new XmlSerializerNamespaces();
namespaces.Add("", DEFAULT_NAMESPACE);
using (var stream = new MemoryStream())
{
var someone = new Person
{
FirstName = "Donald",
LastName = "Duck"
};
serializer.Serialize(stream, someone, namespaces);
stream.Position = 0;
using (var reader = new StreamReader(stream))
{
Console.WriteLine(reader.ReadToEnd());
}
}
}
}
To get the following XML:
<?xml version="1.0"?>
<Person xmlns="http://www.something.org/schema">
<FirstName>Donald</FirstName>
<LastName>Duck</LastName>
</Person>
If you don't want the namespace, just set DEFAULT_NAMESPACE to "".
'Watching' STL containers while debugging is somewhat of a problem. Here are 3 different solutions I have used in the past, none of them is perfect.
1) Use GDB scripts from http://clith.com/gdb_stl_utils/ These scripts allow you to print the contents of almost all STL containers. The problem is that this does not work for nested containers like a stack of sets.
2) Visual Studio 2005 has fantastic support for watching STL containers. This works for nested containers but this is for their implementation for STL only and does not work if you are putting a STL container in a Boost container.
3) Write your own 'print' function (or method) for the specific item you want to print while debugging and use 'call' while in GDB to print the item. Note that if your print function is not being called anywhere in the code g++ will do dead code elimination and the 'print' function will not be found by GDB (you will get a message saying that the function is inlined). So compile with -fkeep-inline-functions
[v[0] for v in sorted(foo.items(), key=lambda(k,v): (v,k))]
I had the same problem with a spring boot project. the solution was to downgrade the jar maven-jar-plugin from 3.2 to 2.6 . i had just to add this to the project pom:
<properties>
<maven-jar-plugin.version>2.6</maven-jar-plugin.version>
</properties>
If you modify your list, then use listIterator()
and iterate from last index (that is size()-1
respectively).
If you fail again, check your list structure.

And I simply got this error because I used a totally different DocumentRoot directory.
My main DocumentRoot was the default /var/www/html
and on the VirtualHost I used /sites/example.com
I have created a link on /var/www/html/example.com

DocumentRoot was set to /var/www/html/example.com
It worked like a charm.
It might be help someone. Similar example.

Code says everything
Since you said you only wanted to pass one parameter and it did not seem to matter which, you could pass the resource identifier in and then find out the string name for it, thus:
String name = getResources().getResourceEntryName(id);
This might be the most efficient way of obtaining both values. You don't have to mess around finding just the "icon" part from a longer string.
Depends on whether you really need to physically concatenate the two vectors or you want to give the appearance of concatenation of the sake of iteration. The boost::join function
http://www.boost.org/doc/libs/1_43_0/libs/range/doc/html/range/reference/utilities/join.html
will give you this.
std::vector<int> v0;
v0.push_back(1);
v0.push_back(2);
v0.push_back(3);
std::vector<int> v1;
v1.push_back(4);
v1.push_back(5);
v1.push_back(6);
...
BOOST_FOREACH(const int & i, boost::join(v0, v1)){
cout << i << endl;
}
should give you
1
2
3
4
5
6
Note boost::join does not copy the two vectors into a new container but generates a pair of iterators (range) that cover the span of both containers. There will be some performance overhead but maybe less that copying all the data to a new container first.
How about this:
$ grep -rl "needle text" my_folder | tr '\n' '\0' | xargs -r -0 file | grep -e ':[^:]*text[^:]*$' | grep -v -e 'executable'
If you want the filenames without the file types, just add a final sed
filter.
$ grep -rl "needle text" my_folder | tr '\n' '\0' | xargs -r -0 file | grep -e ':[^:]*text[^:]*$' | grep -v -e 'executable' | sed 's|:[^:]*$||'
You can filter-out unneeded file types by adding more -e 'type'
options to the last grep
command.
EDIT:
If your xargs
version supports the -d
option, the commands above become simpler:
$ grep -rl "needle text" my_folder | xargs -d '\n' -r file | grep -e ':[^:]*text[^:]*$' | grep -v -e 'executable' | sed 's|:[^:]*$||'
Not really. for backward compatibility it is 32 bits.
If you want 64 bits you have long

I had the same problem with bootstrap datetimepicker extension. Including moment.js before datetimepicker.js was the solution.
What you're trying to accomplish is called Reverse DNS lookup.
socket.gethostbyaddr("IP")
# => (hostname, alias-list, IP)
http://docs.python.org/library/socket.html?highlight=gethostbyaddr#socket.gethostbyaddr
However, for the timeout part I have read about people running into problems with this. I would check out PyDNS or this solution for more advanced treatment.
Check you have <meta charset="utf-8">
inside head block.
Just don't anchor your pattern:
/Test/
The above regex will check for the literal string "Test" being found somewhere within it.
You can use
String hex = String.format("#%02x%02x%02x", r, g, b);
Use capital X's if you want your resulting hex-digits to be capitalized (#FFFFFF
vs. #ffffff
).
Use this line webview.getSettings().setDomStorageEnabled(true) in your java code
WebView webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setDomStorageEnabled(true);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webView.loadUrl(yourUrl);
Starting from Elasticsearch 2.x delete is not anymore allowed, since documents remain in the index causing index corruption.
You need to overload operator <<
for mystruct
class
Something like :-
friend ostream& operator << (ostream& os, const mystruct& m)
{
os << m.m_a <<" " << m.m_b << endl;
return os ;
}
See here
For deep cloning implement Serializable on every class you want to clone like this
public static class Obj implements Serializable {
public int a, b;
public Obj(int a, int b) {
this.a = a;
this.b = b;
}
}
And then use this function:
public static Object deepClone(Object object) {
try {
ByteArrayOutputStream baOs = new ByteArrayOutputStream();
ObjectOutputStream oOs = new ObjectOutputStream(baOs);
oOs.writeObject(object);
ByteArrayInputStream baIs = new ByteArrayInputStream(baOs.toByteArray());
ObjectInputStream oIs = new ObjectInputStream(baIs);
return oIs.readObject();
}
catch (Exception e) {
e.printStackTrace();
return null;
}
}
like this: Obj newObject = (Obj)deepClone(oldObject);
public class RandomNum {
public static void main(String[] args) {
Random rn = new Random();
HashSet<Integer> hSet = new HashSet<>();
while(hSet.size() != 1000) {
hSet.add(rn.nextInt(1000));
}
System.out.println(hSet);
}
}
if (Build.VERSION.SDK_INT >= ApiHelper.VERSION_CODES.HONEYCOMB_MR2) {

If you require to get only one record from database table using codeigniter query then you can do it using row(). we can easily return one row from database in codeigniter.
$data = $this->db->get("items")->row();
Ros the code i post also is for knowing how many services are running...
Imagine you want to know how many services are like Oracle* then you put Oracle instead of NameOfSercive... and you get the number of services like Oracle* running on the variable %CountLines% and if you want to do something if there are only 4 you can do something like this:
IF 4==%CountLines% GOTO FourServicesAreRunning
That is much more powerfull... and your code does not let you to know if desired service is running ... if there is another srecive starting with same name... imagine: -ServiceOne -ServiceOnePersonal
If you search for ServiceOne, but it is only running ServiceOnePersonal your code will tell ServiceOne is running...
My code can be easly changed, since it reads all lines of the file and read line by line it can also do whatever you want to each service... see this:
@ECHO OFF
REM Put here any code to be run before check for Services
SET TemporalFile=TemporalFile.TXT
NET START > %TemporalFile%
SET CountLines=0
FOR /F "delims=" %%X IN (%TemporalFile%) DO SET /A CountLines=1+CountLines
SETLOCAL EnableDelayedExpansion
SET CountLine=0
FOR /F "delims=" %%X IN (%TemporalFile%) DO @(
SET /A CountLine=1+CountLine
REM Do whatever you want to each line here, remember first and last are special not service names
IF 1==!CountLine! (
REM Do whatever you want with special first line, not a service.
) ELSE IF %CountLines%==!CountLine! (
REM Do whatever you want with special last line, not a service.
) ELSE (
REM Do whatever you want with rest lines, for each service.
REM For example echo its position number and name:
echo !CountLine! - %%X
REM Or filter by exact name (do not forget to not remove the three spaces at begining):
IF " NameOfService"=="%%X" (
REM Do whatever you want with Service filtered.
)
)
REM Do whatever more you want to all lines here, remember two first are special as last one
)
DEL -P %TemporalFile% 2>nul
SET TemporalFile=
REM Put here any code to be run after check for Services
Of course it only list running services, i do not know any way net can list not running services...
Hope this helps!!!
Let me explain with an example
create emp DataFrame
import spark.sqlContext.implicits._ val emp = Seq((1,"Smith",-1,"2018","10","M",3000), (2,"Rose",1,"2010","20","M",4000), (3,"Williams",1,"2010","10","M",1000), (4,"Jones",2,"2005","10","F",2000), (5,"Brown",2,"2010","40","",-1), (6,"Brown",2,"2010","50","",-1) ) val empColumns = Seq("emp_id","name","superior_emp_id","year_joined", "emp_dept_id","gender","salary")
val empDF = emp.toDF(empColumns:_*)
Create dept DataFrame
val dept = Seq(("Finance",10), ("Marketing",20), ("Sales",30), ("IT",40) )
val deptColumns = Seq("dept_name","dept_id") val deptDF = dept.toDF(deptColumns:_*)
Now let's join emp.emp_dept_id with dept.dept_id
empDF.join(deptDF,empDF("emp_dept_id") === deptDF("dept_id"),"inner")
.show(false)
This results below
+------+--------+---------------+-----------+-----------+------+------+---------+-------+
|emp_id|name |superior_emp_id|year_joined|emp_dept_id|gender|salary|dept_name|dept_id|

In host computer/server go to Sql server management studio --> open Security Section on left hand --> right click on Login, select New Login and then create a new account for your database which you want to connect to.
Check the TCP/IP Protocol is Enable. go to All programs --> Microsoft SQL server 2008 --> Configuration Tools --> open Sql server configuration manager. On the left hand select client protocols (based on your operating system 32/64 bit). On the right hand, check TCP/IP Protocol be Enabled.
In Remote computer/server, open Data source administrator. Control panel --> Administrative tools --> Data sources (ODBC).
In User DSN or System DSN , click Add button and select Sql Server driver and then press Finish.
Enter Name.
Enter Server, note that: if you want to enter host computer address, you should enter that`s IP address without "\\". eg. 192.168.1.5 and press Next.

Like the other answers, it's impossible. Here is the comment about breaker in underscore underscore issue #21
Use String#replace()
.
To replace them with spaces (as per your question title):
System.out.println("I don't like these \"double\" quotes".replace("\"", " "));
The above can also be done with characters:
System.out.println("I don't like these \"double\" quotes".replace('"', ' '));
To remove them (as per your example):
System.out.println("I don't like these \"double\" quotes".replace("\"", ""));
Just by using select select
you can select particular columns, give them readable names and cast them. For example like this:
spark.read.csv(path).select(
'_c0.alias("stn").cast(StringType),
'_c1.alias("wban").cast(StringType),
'_c2.alias("lat").cast(DoubleType),
'_c3.alias("lon").cast(DoubleType)
)
.where('_c2.isNotNull && '_c3.isNotNull && '_c2 =!= 0.0 && '_c3 =!= 0.0)
no it doesnt. break is for loops, not ifs.
nested if statements are just terrible. If you can avoid them, avoid them. Can you rewrite your code to be something like
if (c1 && c2) {
//sequence 1
} else if (c3 && c2) {
// sequence 3
}
that way you don't need any control logic to 'break out' of the loop.
The simple and basic way (guzzle6):
$client = new Client([
'headers' => [ 'Content-Type' => 'application/json' ]
]);
$response = $client->post('http://api.com/CheckItOutNow',
['body' => json_encode(
[
'hello' => 'World'
]
)]
);
To get the response status code and the content of the body I did this:
echo '<pre>' . var_export($response->getStatusCode(), true) . '</pre>';
echo '<pre>' . var_export($response->getBody()->getContents(), true) . '</pre>';
You will have to provide a link to your file that is accessible through the browser, that is for instance:
<a href="http://my.domain.com/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">
versus
<a href="C:/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">
If you expose your "Projecten" folder directly to the public, then you may only have to provide the link as such:
<a href="/Projecten/Protocollen/346/Uitvoeringsoverzicht.xls">
But beware, that your files can then be indexed by search engines, can be accessed by anybody having this link, etc.

Rob W answer helped me figure out how to pause a video over iframe when a slider is hidden. Yet, I needed some modifications before I could get it to work. Here is snippet of my html:
<div class="flexslider" style="height: 330px;">
<ul class="slides">
<li class="post-64"><img src="http://localhost/.../Banner_image.jpg"></li>
<li class="post-65><img src="http://localhost/..../banner_image_2.jpg "></li>
<li class="post-67 ">
<div class="fluid-width-video-wrapper ">
<iframe frameborder="0 " allowfullscreen=" " src="//www.youtube.com/embed/video-ID?enablejsapi=1 " id="fitvid831673 "></iframe>
</div>
</li>
</ul>
</div>
Observe that this works on localhosts and also as Rob W mentioned "enablejsapi=1" was added to the end of the video URL.
Following is my JS file:
jQuery(document).ready(function($){
jQuery(".flexslider").click(function (e) {
setTimeout(checkiframe, 1000); //Checking the DOM if iframe is hidden. Timer is used to wait for 1 second before checking the DOM if its updated
});
});
function checkiframe(){
var iframe_flag =jQuery("iframe").is(":visible"); //Flagging if iFrame is Visible
console.log(iframe_flag);
var tooglePlay=0;
if (iframe_flag) { //If Visible then AutoPlaying the Video
tooglePlay=1;
setTimeout(toogleVideo, 1000); //Also using timeout here
}
if (!iframe_flag) {
tooglePlay =0;
setTimeout(toogleVideo('hide'), 1000);
}
}
function toogleVideo(state) {
var div = document.getElementsByTagName("iframe")[0].contentWindow;
func = state == 'hide' ? 'pauseVideo' : 'playVideo';
div.postMessage('{"event":"command","func":"' + func + '","args":""}', '*');
};

I encountered difficulties with Roi-Kyi Bryant's solution when multiple add-ins tried to modify the ribbon. I also don't have admin access on my work-computer, which ruled out installing the Custom UI Editor
. So, if you're in the same boat as me, here's an alternative example to customising the ribbon using only Excel. Note, my solution is derived from the Microsoft guide.
.xlam
files, Chart Tools.xlam
and Priveleged UDFs.xlam
, to demonstrate how multiple add-ins can interact with the Ribbon. customUI
and _rels
folder.customUI
folder, create a customUI.xml
file. The customUI.xml
file details how Excel files interact with the ribbon. Part 2 of the Microsoft guide covers the elements in the customUI.xml
file.My customUI.xml
file for Chart Tools.xlam
looks like this
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">

.zip
to their file name. In my case, I renamed Chart Tools.xlam
to Chart Tools.xlam.zip
, and Privelged UDFs.xlam
to Priveleged UDFs.xlam.zip
..zip
file, and navigate to the _rels
folder. Copy the .rels
file to the _rels
folder you created in Step 3. Edit each .rels
file with a text editor. From the Microsoft guideBetween the final
<Relationship>
element and the closing<Relationships>
element, add a line that creates a relationship between the document file and the customization file. Ensure that you specify the folder and file names correctly.
<Relationship Type="http://schemas.microsoft.com/office/2006/
relationships/ui/extensibility" Target="/customUI/customUI.xml"

files in each .zip
file with the .rels
file/files you modified in the previous step..customUI
folder you created into the home directory of the .zip
file/files..zip
file extension from the Excel files you created..xlam
files, back in Excel, add them to your Excel add-ins.onAction
keywords in my buttons. The onAction
keyword indicates that, when the containing element is triggered, the Excel application will trigger the sub-routine encased in quotation marks directly after the onAction
keyword. This is known as a callback. In my .xlam
files, I have a module called CallBacks
where I've included my callback sub-routines.My CallBacks
module for Chart Tools.xlam
looks like
Option Explicit
Public Sub MoveChartWithRelativeLinksCallBack(ByRef control As IRibbonControl)
MoveChartWithRelativeLinks
End Sub
Public Sub MoveChartToManySheetsWithRelativeLinksCallBack(ByRef control As IRibbonControl)
MoveChartToManySheetsWithRelativeLinks
End Sub
Public Sub DeleteAllChartsInWorkbookSharingAnAddressCallBack(ByRef control As IRibbonControl)
DeleteAllChartsInWorkbookSharingAnAddress
End Sub
My CallBacks
module for Priveleged UDFs.xlam
looks like
Option Explicit
Public Sub InitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
ThisWorkbook.InitialisePrivelegedUDFs
End Sub
Public Sub DeInitialisePrivelegedUDFsCallBack(ByRef control As IRibbonControl)
ThisWorkbook.DeInitialisePrivelegedUDFs
End Sub
Different elements have a different callback sub-routine signature. For buttons, the required sub-routine parameter is ByRef control As IRibbonControl
. If you don't conform to the required callback signature, you will receive an error while compiling your VBA project/projects. Part 3 of the Microsoft guide defines all the callback signatures.
Here's what my finished example looks like
Some closing tips
idQ
and xlmns:
keyword. In my example, the Chart Tools.xlam
and Priveleged UDFs.xlam
both have access to the elements with idQ
's equal to x:chartToolsTab
and x:privelgedUDFsTab
. For this to work, the x:
is required, and, I've defined its namespace in the first line of my customUI.xml
file, <customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="sao">
. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.isMSO
keyword. The section Two Ways to Customize the Fluent UI in the Microsoft guide gives some more details.Below code will break the foreach loop once the condition is met, below is the sample example
var array = [1,2,3,4,5];
var newArray = array.slice(0,array.length);
array.forEach(function(item,index){
//your breaking condition goes here example checking for value 2
if(item == 2){
array.length = array.indexOf(item);
}
})
array = newArray;
If you are using Razor, you cannot access the field directly, but you can manage its value.
The idea is that the first Microsoft approach drive the developers away from Web Development and make it easy for Desktop programmers (for example) to make web applications.
Meanwhile, the web developers, did not understand this tricky strange way of ASP.NET.
Actually this hidden input is rendered on client-side, and the ASP has no access to it (it never had). However, in time you will see its a piratical way and you may rely on it, when you get use with it. The web development differs from the Desktop or Mobile.
The model is your logical unit, and the hidden field (and the whole view page) is just a representative view of the data. So you can dedicate your work on the application or domain logic and the view simply just serves it to the consumer - which means you need no detailed access and "brainstorming" functionality in the view.
The controller actually does work you need for manage the hidden or general setup. The model serves specific logical unit properties and functionality and the view just renders it to the end user, simply said. Read more about MVC.
Model
public class MyClassModel
{
public int Id { get; set; }
public string Name { get; set; }
public string MyPropertyForHidden { get; set; }
}
This is the controller aciton
public ActionResult MyPageView()
{
MyClassModel model = new MyClassModel(); // Single entity, strongly-typed
// IList model = new List<MyClassModel>(); // or List, strongly-typed
// ViewBag.MyHiddenInputValue = "Something to pass"; // ...or using ViewBag
return View(model);
}
The view is below
//This will make a Model property of the View to be of MyClassModel
@model MyNamespace.Models.MyClassModel // strongly-typed view
// @model IList<MyNamespace.Models.MyClassModel> // list, strongly-typed view
// ... Some Other Code ...
@using(Html.BeginForm()) // Creates <form>
{
// Renders hidden field for your model property (strongly-typed)
// The field rendered to server your model property (Address, Phone, etc.)
Html.HiddenFor(model => Model.MyPropertyForHidden);
// For list you may use foreach on Model
// foreach(var item in Model) or foreach(MyClassModel item in Model)
}
// ... Some Other Code ...
The view with ViewBag:
// ... Some Other Code ...
@using(Html.BeginForm()) // Creates <form>
{
Html.Hidden(
"HiddenName",
ViewBag.MyHiddenInputValue,
new { @class = "hiddencss", maxlength = 255 /*, etc... */ }
);
}
// ... Some Other Code ...
We are using Html Helper to render the Hidden field or we could write it by hand - <input name=".." id=".." value="ViewBag.MyHiddenInputValue">
also.
The ViewBag is some sort of data carrier to the view. It does not restrict you with model - you can place whatever you like.
Or you don't have to use IBOutlet to refer to the object in the view. You can give the Label in the tableViewCell a Tag value, for example set the Tag to 123 (this can be done by the attributes inspector). Then you can access the label by
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "someID", for: indexPath)
let label = cell.viewWithTag(123) as! UILabel //refer the label by Tag
switch indexPath.row {
case 0:
label.text = "Hello World!"
default:
label.text = "Default"
}
return cell
}
One can also use the java.util.EnumSet like this
@Test
void test(){
Enum aEnum =DayOfWeek.MONDAY;
printAll(aEnum);
}
void printAll(Enum value){
Set allValues = EnumSet.allOf(value.getClass());
System.out.println(allValues);
}
this one is pretty good and it also works in angular 2
$("#modal .close").click()
Just a minor addition: if you add the -c
flag to ps, you don't need to remove the line containing the grep process with grep -v
afterwards. I.e.
ps acux | grep cron
is all the typing you'll need on a bsd-ish system (this includes MacOSX) You can leave the -u
away if you need less information.
On a system where the genetics of the native ps
command point back to SysV, you'd use
ps -e |grep cron
or
ps -el |grep cron
for a listing containing more than just pid and process name. Of course you could select the specific fields to print out using the -o <field,field,...>
option.
www.example.com:443:0 server certificate does NOT include an ID which matches the server name
I was getting this error when trying to start Apache, there is no error with Apache. It's an dependency error on windows 8 - probably the same for 7. Just right click and run as Admin :)
If you're still getting an error check your Antivirus/Firewall is not blocking Xampp or port 443.
cURL-less you can use in php5
$url = 'URL';
$data = array('field1' => 'value', 'field2' => 'value');
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data),
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);
There is a third option - using stream().toArray()
- see comments under why didn't stream have a toList method. It turns out to be slower than forEach() or collect(), and less expressive. It might be optimised in later JDK builds, so adding it here just in case.
assuming List<String>
myFinalList = Arrays.asList(
myListToParse.stream()
.filter(Objects::nonNull)
.map(this::doSomething)
.toArray(String[]::new)
);
with a micro-micro benchmark, 1M entries, 20% nulls and simple transform in doSomething()
private LongSummaryStatistics benchmark(final String testName, final Runnable methodToTest, int samples) {
long[] timing = new long[samples];
for (int i = 0; i < samples; i++) {
long start = System.currentTimeMillis();
methodToTest.run();
timing[i] = System.currentTimeMillis() - start;
}
final LongSummaryStatistics stats = Arrays.stream(timing).summaryStatistics();
System.out.println(testName + ": " + stats);
return stats;
}
the results are
parallel:
toArray: LongSummaryStatistics{count=10, sum=3721, min=321, average=372,100000, max=535}
forEach: LongSummaryStatistics{count=10, sum=3502, min=249, average=350,200000, max=389}
collect: LongSummaryStatistics{count=10, sum=3325, min=265, average=332,500000, max=368}
sequential:
toArray: LongSummaryStatistics{count=10, sum=5493, min=517, average=549,300000, max=569}
forEach: LongSummaryStatistics{count=10, sum=5316, min=427, average=531,600000, max=571}
collect: LongSummaryStatistics{count=10, sum=5380, min=444, average=538,000000, max=557}
parallel without nulls and filter (so the stream is SIZED
):
toArrays has the best performance in such case, and .forEach()
fails with "indexOutOfBounds" on the recepient ArrayList, had to replace with .forEachOrdered()
toArray: LongSummaryStatistics{count=100, sum=75566, min=707, average=755,660000, max=1107}
forEach: LongSummaryStatistics{count=100, sum=115802, min=992, average=1158,020000, max=1254}
collect: LongSummaryStatistics{count=100, sum=88415, min=732, average=884,150000, max=1014}
If you are going to be doing this frequently, adding an extension makes your code more readable. Button extends TextView; use Button if you want to be more narrow.
fun TextView.leftDrawable(@DrawableRes id: Int = 0) {
this.setCompoundDrawablesWithIntrinsicBounds(id, 0, 0, 0)
}
To use the extension, simply call
view.leftDrawable(R.drawable.my_drawable)
Anytime you need to clear, don't pass a param or make another extension called removeDrawables
I think your only option will be diruse (a highly supported 3rd party solution):
Get file/directory size from command line
The Windows CLI is unfortuntely quite restrictive, you could alternatively install Cygwin which is a dream to use compared to cmd. That would give you access to the ported Unix tool du which is the basis of diruse on windows.
Sorry I wasn't able to answer your questions directly with a command you can run on the native cli.
Yes, there is. For example, if you wanted to get the content of the first section of the article Stack Overflow, use a query like this:
The parts mean this:
format=xml
: Return the result formatter as XML. Other options (like JSON) are available. This does not affect the format of the page content itself, only the enclosing data format.
action=query&prop=revisions
: Get information about the revisions of the page. Since we don't specify which revision, the latest one is used.
titles=Stack%20Overflow
: Get information about the page Stack Overflow
. It's possible to get the text of more pages in one go, if you separate their names by |
.
rvprop=content
: Return the content (or text) of the revision.
rvsection=0
: Return only content from section 0.
rvparse
: Return the content parsed as HTML.
Keep in mind that this returns the whole first section including things like hatnotes (“For other uses …”), infoboxes or images.
There are several libraries available for various languages that make working with API easier, it may be better for you if you used one of them.
My solution using standard <ul>
and <i>
inside <li>
<ul>
<li><i class="fab fa-cc-paypal"></i> <div>Paypal</div></li>
<li><i class="fab fa-cc-apple-pay"></i> <div>Apple Pay</div></li>
<li><i class="fab fa-cc-stripe"></i> <div>Stripe</div></li>
<li><i class="fab fa-cc-visa"></i> <div>VISA</div></li>
</ul>
I've found the same thing, but only on emulators that have the Use Host GPU setting ticked. Try turning that off, you'll no longer see those warnings (and the emulator will run horribly, horribly slowly..)
In my experience those warnings are harmless. Notice that the "error" is EGL_SUCCESS, which would seem to indicate no error at all!
The best way is to build your script in a way it cannot create any errors! When there is something that can create a Notice or an Error there is something wrong with your script and the checking of variables and environment!
If you want to hide them anyway: error_reporting(0);
