Ok I finally worked this out. This is using TortoiseHg on Windows. If you're not using that you can do it on the command line.
hggit
:Open a command line, enter an empty directory.
git init --bare .git
(If you don't use a bare repo you'll get an error like abort: git remote error: refs/heads/master failed to update
cd
to your Mercurial repository.
hg bookmarks hg
hg push c:/path/to/your/git/repo
In the Git directory: git config --bool core.bare false
(Don't ask me why. Something about "work trees". Git is seriously unfriendly. I swear writing the actual code is easier than using Git.)
Hopefully it will work and then you can push from that new git repo to a non-bare one.
_.each(['Hello', 'World!'], function(word){_x000D_
console.log(word);_x000D_
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
_x000D_
Here's simple example that could use _.each
:
function basket() {_x000D_
this.items = [];_x000D_
this.addItem = function(item) {_x000D_
this.items.push(item);_x000D_
};_x000D_
this.show = function() {_x000D_
console.log('items: ', this.items);_x000D_
}_x000D_
}_x000D_
_x000D_
var x = new basket();_x000D_
x.addItem('banana');_x000D_
x.addItem('apple');_x000D_
x.addItem('kiwi');_x000D_
x.show();
_x000D_
Output:
items: [ 'banana', 'apple', 'kiwi' ]
Instead of calling addItem
multiple times you could use underscore this way:
_.each(['banana', 'apple', 'kiwi'], function(item) { x.addItem(item); });
which is identical to calling addItem
three times sequentially with these items. Basically it iterates your array and for each item calls your anonymous callback function that calls x.addItem(item)
. The anonymous callback function is similar to addItem
member function (e.g. it takes an item) and is kind of pointless. So, instead of going through anonymous function it's better that _.each
avoids this indirection and calls addItem
directly:
_.each(['banana', 'apple', 'kiwi'], x.addItem);
but this won't work, as inside basket's addItem
member function this
won't refer to your x
basket that you created. That's why you have an option to pass your basket x
to be used as [context]
:
_.each(['banana', 'apple', 'kiwi'], x.addItem, x);
function basket() {_x000D_
this.items = [];_x000D_
this.addItem = function(item) {_x000D_
this.items.push(item);_x000D_
};_x000D_
this.show = function() {_x000D_
console.log('items: ', this.items);_x000D_
}_x000D_
}_x000D_
var x = new basket();_x000D_
_.each(['banana', 'apple', 'kiwi'], x.addItem, x);_x000D_
x.show();
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
_x000D_
In short, if callback function that you pass to _.each
in any way uses this
then you need to specify what this
should be referring to inside your callback function. It may seem like x
is redundant in my example, but x.addItem
is just a function and could be totally unrelated to x
or basket
or any other object, for example:
function basket() {_x000D_
this.items = [];_x000D_
this.show = function() {_x000D_
console.log('items: ', this.items);_x000D_
}_x000D_
}_x000D_
function addItem(item) {_x000D_
this.items.push(item);_x000D_
};_x000D_
_x000D_
var x = new basket();_x000D_
_.each(['banana', 'apple', 'kiwi'], addItem, x);_x000D_
x.show();
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"></script>
_x000D_
In other words, you bind some value to this
inside your callback, or you may as well use bind directly like this:
_.each(['banana', 'apple', 'kiwi'], addItem.bind(x));
how this feature can be useful with some different underscore methods?
In general, if some underscorejs
method takes a callback function and if you want that callback be called on some member function of some object (e.g. a function that uses this
) then you may bind that function to some object or pass that object as the [context]
parameter and that's the primary intention. And at the top of underscorejs documentation, that's exactly what they state: The iteratee is bound to the context object, if one is passed
The problem is your query returned false
meaning there was an error in your query. After your query you could do the following:
if (!$result) {
die(mysqli_error($link));
}
Or you could combine it with your query:
$results = mysqli_query($link, $query) or die(mysqli_error($link));
That will print out your error.
Also... you need to sanitize your input. You can't just take user input and put that into a query. Try this:
$query = "SELECT * FROM shopsy_db WHERE name LIKE '%" . mysqli_real_escape_string($link, $searchTerm) . "%'";
In reply to: Table 'sookehhh_shopsy_db.sookehhh_shopsy_db' doesn't exist
Are you sure the table name is sookehhh_shopsy_db? maybe it's really like users or something.
Here is a JavaScript implementation of the Y-Combinator and the Factorial function (from Douglas Crockford's article, available at: http://javascript.crockford.com/little.html).
function Y(le) {
return (function (f) {
return f(f);
}(function (f) {
return le(function (x) {
return f(f)(x);
});
}));
}
var factorial = Y(function (fac) {
return function (n) {
return n <= 2 ? n : n * fac(n - 1);
};
});
var number120 = factorial(5);
I know it's not XAML, but I did the same thing with SizeChanged event of the textbox:
private void TextBlock_SizeChanged(object sender, SizeChangedEventArgs e)
{
TextBlock textBlock = sender as TextBlock;
FrameworkElement element = textBlock.Parent as FrameworkElement;
textBlock.Margin = new Thickness(0, 0, (element.ActualWidth / 100) * 20, 0);
}
The textbox appears to be 80% size of its parent (well right side margin is 20%) and stretches when needed.
Solved the problem, when moved the folder with the image in src folder. Then I turned to the image (project created through "create-react-app")
let image = document.createElement("img");
image.src = require('../assets/police.png');
Technically there is no direct way to do this. However, you can sort that out with either jQuery or JavaScript.
However, you can do something like this as well.
a.active h1 {color: blue;}
a.active p {color: green;}
jQuery
$("a.active").parents('li').css("property", "value");
If you want to achieve this using jQuery here is the reference for the jQuery parent selector.

3 years of experience later, I've come back to this question and would suggest to write it like this:
string output = new JavaScriptSerializer().Serialize(ListOfMyObject);
One line of code.
argc
is the number of command line arguments and argv
is array of strings representing command line arguments.
This gives you the option to react to the arguments passed to the program. If you are expecting none, you might as well use int main
.
There's a good talk by some people who were on the ECMAScript committee: Changes to JavaScript, Part 1: ECMAScript 5" about how incremental use of the "use strict"
switch allows JavaScript implementers to clean up a lot of the dangerous features of JavaScript without suddenly breaking every website in the world.
Of course it also talks about just what a lot of those misfeatures are (were) and how ECMAScript 5 fixes them.
You can try something like this:
CSS
div {
width:200px;
height:200px;
background: url(img1.png) center center no-repeat;
}
.visited {
background: url(img2.png) center center no-repeat;
}
HTML
<div href="#" onclick="this.className='visited'">
<p>Content</p>
</div>
Simplest way to find used view or stored procedure for the tableName using below query -
exec dbo.dbsearch 'Your_Table_Name'
I came across this post and went back to an approach that I used some time ago which is similar to @MadAntrax's.
The main difference is that it uses a VBScript user-defined class to wrap all the logic for switching to CScript and outputting text to the console, so it makes the main script a bit cleaner.
This assumes that your objective is to stream output to the console, rather than having output go to message boxes.
The cCONSOLE class is below. To use it, include the complete class at the end of your script, and then instantiate it right at the beginning of the script. Here is an example:
Option Explicit
'// Instantiate the console object, this automatically switches to CSCript if required
Dim CONS: Set CONS = New cCONSOLE
'// Now we can use the Consol object to write to and read from the console
With CONS
'// Simply write a line
.print "CSCRIPT Console demo script"
'// Arguments are passed through correctly, if present
.Print "Arg count=" & wscript.arguments.count
'// List all the arguments on the console log
dim ix
for ix = 0 to wscript.arguments.count -1
.print "Arg(" & ix & ")=" & wscript.arguments(ix)
next
'// Prompt for some text from the user
dim sMsg : sMsg = .prompt( "Enter any text:" )
'// Write out the text in a box
.Box sMsg
'// Pause with the message "Hit enter to continue"
.Pause
End With

For Android development, I use:
int color = Color.parseColor("#123456");
One difference we can note in Windows is:
If you use Runtime.getRuntime().exec("rmiregistry 1024");
you can see rmiregistry.exe process will run in your Task Manager
whereas if you use Registry registry = LocateRegistry.createRegistry(1024);
you can not see the process running in Task Manager,
I think Java handles it in a different way.
and this is my server.policy file
Before running the the application, make sure that you killed all your existing javaw.exe and rmiregistry.exe corresponds to your rmi programs which are already running.
The following code works for me by using Registry.LocateRegistry()
or
Runtime.getRuntime.exec("");
// Standard extensions get all permissions by default
grant {
permission java.security.AllPermission;
};
VM argument
-Djava.rmi.server.codebase=file:\C:\Users\Durai\workspace\RMI2\src\
Code:
package server;
import java.rmi.Naming;
import java.rmi.RMISecurityManager;

{
public static void main (String[] argv)
{
try {
if(System.getSecurityManager()==null){
System.setProperty("java.security.policy","C:\\Users\\Durai\\workspace\\RMI\\src\\server\\server.policy");
System.setSecurityManager(new RMISecurityManager());
}
Runtime.getRuntime().exec("rmiregistry 1024");
// Registry registry = LocateRegistry.createRegistry(1024);
// registry.rebind ("Hello", new Hello ("Hello,From Roseindia.net pvt ltd!"));
//Process process = Runtime.getRuntime().exec("C:\\Users\\Durai\\workspace\\RMI\\src\\server\\rmi_registry_start.bat");
Naming.rebind ("//localhost:1024/Hello",new Hello ("Hello,From Roseindia.net pvt ltd!"));

If you are using RemoteDriver things are different. From http://element34.ca/blog/iedriverserver-webdriver-and-python :
You will need to start the server using a line like
java -jar selenium-server-standalone-2.26.0.jar -Dwebdriver.ie.driver=C:\Temp\IEDriverServer.exe
I found that if the IEDriverServer.exe was in C:\Windows\System32\
or its subfolders, it couldn't be found automatically (even though System32 was in the %PATH%
) or explicitly using the -D flag.
shuckc's answer for echoing select lines has a few downsides: you end up with the following set +x
command being echoed as well, and you lose the ability to test the exit code with $?
since it gets overwritten by the set +x
.
Another option is to run the command in a subshell:
echo "getting URL..."
( set -x ; curl -s --fail $URL -o $OUTFILE )
if [ $? -eq 0 ] ; then
echo "curl failed"
exit 1
fi
which will give you output like:
getting URL...
+ curl -s --fail http://example.com/missing -o /tmp/example
curl failed
This does incur the overhead of creating a new subshell for the command, though.

You can use typeof
operator:
var booleanValue = true;
var numericalValue = 354;
var stringValue = "This is a String";
var stringObject = new String( "This is a String Object" );
alert(typeof booleanValue) // displays "boolean"
alert(typeof numericalValue) // displays "number"
alert(typeof stringValue) // displays "string"
alert(typeof stringObject) // displays "object"
Example from this webpage. (Example was slightly modified though).
This won't work as expected in the case of strings created with new String()
, but this is seldom used and recommended against[1][2]. See the other answers for how to handle these, if you so desire.
The main()
method is the entry point for a Java application. run()
is typically used for new threads or tasks.
Where have you been writing a run()
method, what kind of application are you writing (e.g. Swing, AWT, console etc) and what's your development environment?
The thread is old, but maybe someone is still interested. The shortest form I found is further improvement on the example from ?lex and bmargulies. The execution tag will look like:
<execution>
<id>TheNameOfTheRelevantExecution</id>
<phase/>
</execution>

After posting found it is already in stackoverflow: In a Maven multi-module project, how can I disable a plugin in one child?
To make the application remember the last selected spinner values, you can use below code:
Below code reads the spinner value and sets the spinner position accordingly.
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
int spinnerPosition;
Spinner spinner1 = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<CharSequence> adapter1 = ArrayAdapter.createFromResource(
this, R.array.ccy_array,
android.R.layout.simple_spinner_dropdown_item);
adapter1.setDropDownViewResource(android.R.layout.simple_list_item_activated_1);
// Apply the adapter to the spinner
spinner1.setAdapter(adapter1);
// changes to remember last spinner position
spinnerPosition = 0;
String strpos1 = prfs.getString("SPINNER1_VALUE", "");
if (strpos1 != null || !strpos1.equals(null) || !strpos1.equals("")) {
strpos1 = prfs.getString("SPINNER1_VALUE", "");
spinnerPosition = adapter1.getPosition(strpos1);
spinner1.setSelection(spinnerPosition);
spinnerPosition = 0;
}
And put below code where you know latest spinner values are present, or somewhere else as required. This piece of code basically writes the spinner value in SharedPreferences.
Spinner spinner1 = (Spinner) findViewById(R.id.spinner1);
String spinlong1 = spinner1.getSelectedItem().toString();
SharedPreferences prfs = getSharedPreferences("WHATEVER",
Context.MODE_PRIVATE);
SharedPreferences.Editor editor = prfs.edit();
editor.putString("SPINNER1_VALUE", spinlong1);
editor.commit();
The &&
function is not vectorized. You need the &
function:
EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]
Duplicate question which basically says use ExecuteScalar()
instead.
I have a simple solution on handling home button press. Here is my code, it can be useful:
public class LifeCycleActivity extends Activity {
boolean activitySwitchFlag = false;
@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if(keyCode == KeyEvent.KEYCODE_BACK)
{
activitySwitchFlag = true;
// activity switch stuff..
return true;
}
return false;
}
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public void onPause(){
super.onPause();
Log.v("TAG", "onPause" );
if(activitySwitchFlag)
Log.v("TAG", "activity switch");
else
Log.v("TAG", "home button");
activitySwitchFlag = false;
}
public void gotoNext(View view){
activitySwitchFlag = true;
startActivity(new Intent(LifeCycleActivity.this, NextActivity.class));
}
}
As a summary, put a boolean in the activity, when activity switch occurs(startactivity event), set the variable and in onpause event check this variable..
i'd suggest shorter and faster approach:
printf("%.2f", ((signed long)(fVal * 100) * 0.01f));
this way you won't overflow int, plus multiplication by 100 shouldn't influence the significand/mantissa itself, because the only thing that really is changing is exponent.
Its an old question, but this is a unique approach that can help in several cases.

Because normal flow is 'top-to-bottom' we can't simply ask the #copyright
div to stick to the bottom of his parent without absolutely positioning of some sort, But if we wanted the #copyright
div to stick to the top of his parent, it will be very simple - because this is the normal flow way.
So we will use this in our advantage.
we will change the order of the div
s in the HTML, now the #copyright
div is at the top, and the content follow it right away.
we also make the content div stretch all the way (using pseudo elements and clearing techniques)
now it's just a matter of inverting that order back in the view. that can be easily done with CSS transform.
We rotate the container by 180deg, and now: up-is-down. (and we inverse back the content to look normal again)
If we want to have a scroolbar within the content area, we need to apply a little bit more of CSS magic. as can be showed Here [in that example, the content is below a header - but its the same idea]

The sqlite answer is
update TABLE set mydatetime = datetime('now');
in case someone else was looking for it.
You can use sudo ip link delete
to remove the interface.
In droupDown list there are two item add property.
1) Text 2) value
If you want to get text property then u use selecteditem.text
and If you want to select value property then use selectedvalue property
In your case i thing both value and text property are the same so no matter if u use selectedvalue or selecteditem.text
If both are different then they give us different results
You probably want the isinstance
builtin function:
self.data = data if isinstance(data, list) else self.parse(data)
Try the following:
PreparedStatementCreator creator = new PreparedStatementCreator() {
@Override
public PreparedStatement createPreparedStatement(Connection con) throws SQLException {
PreparedStatement updateSales = con.prepareStatement(
"UPDATE COFFEES SET SALES = ? WHERE COF_NAME LIKE ? ");
updateSales.setInt(1, 75);
updateSales.setString(2, "Colombian");
return updateSales;
}
};
Here, There are two things inside the domain
So you want to style those two sections as follows,
1. Style for the iFrame Section
It can style using CSS with that respected id
or class
name. You can just style it in your parent Style sheets also.
<style>
#my_iFrame{
height: 300px;
width: 100%;
position:absolute;
top:0;
left:0;
border: 1px black solid;
}
</style>
<iframe name='iframe1' id="my_iFrame" src="#" cellspacing="0"></iframe>
2. Style the Page Loaded inside the iFrame
This Styles can be loaded from the parent page with the help of Javascript
var cssFile = document.createElement("link")
cssFile.rel = "stylesheet";
cssFile.type = "text/css";
cssFile.href = "iFramePage.css";
then set that CSS file to the respected iFrame section
//to Load in the Body Part
frames['my_iFrame'].document.body.appendChild(cssFile);
//to Load in the Head Part
frames['my_iFrame'].document.head.appendChild(cssFile);
Here, You can edit the Head Part of the Page inside the iFrame using this way also
var $iFrameHead = $("#my_iFrame").contents().find("head");
$iFrameHead.append(
$("<link/>",{
rel: "stylesheet",
href: urlPath,
type: "text/css" }
));
You can do it with an confirm()
message using Javascript.
To access a variable in a class, you must use $this->myVar
instead of $this->$myvar
.
And, you should use access identifier to declare a variable instead of var
.
Please read the doc here.
The Pythonic way of summing an array is using sum
. For other purposes, you can sometimes use some combination of reduce
(from the functools
module) and the operator
module, e.g.:
def product(xs):
return reduce(operator.mul, xs, 1)
Be aware that reduce
is actually a foldl
, in Haskell terms. There is no special syntax to perform folds, there's no builtin foldr
, and actually using reduce
with non-associative operators is considered bad style.
Using higher-order functions is quite pythonic; it makes good use of Python's principle that everything is an object, including functions and classes. You are right that lambdas are frowned upon by some Pythonistas, but mostly because they tend not to be very readable when they get complex.
Python supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long
and is separate from the int
type, but the interpreter will automatically use whichever is more appropriate. In Python 3.0+, the int
type has been dropped completely.
That's just an implementation detail, though — as long as you have version 2.5 or better, just perform standard math operations and any number which exceeds the boundaries of 32-bit math will be automatically (and transparently) converted to a bignum.
You can find all the gory details in PEP 0237.
I think intellij is the best option for android. i have used both eclipse and intellij and found intellij is much easier to use with android as compared to eclipse because of these reasons :-
Intellij provides a built-in support for android and you don't have to configure it as you need to do with eclipse. Intellij gives you auto-lookup feature which is really important for developer like us to increase our productivity. And if we talk about eclipse you have to type each and every method, classname etc on your own. (May be eclipse has this feature too but i never found it and trust me i tried to find it like anything) Its much more user friendly and easy to use than eclipse. I hope it will help you and other members of stack overflow to decide which IDE is best for Android development.
My personal choice is Intellij.
EDIT
But there is one thing i love about eclipse and that is visual layout creator. You can use drag and drop technique to create a layout and eclipse will automatically generate an XML file for you just like XCODE.
EDIT
Good News!! Intellij added a new feature which shows how your app's view is going to look like. It doesn't work exactly like Eclipse but it will give you a good idea about your layout.
My personal choice is still Intellij because it helps me to type faster than eclipse.
EDIT
Ok guys these days i am using eclipse juno and found its kind of buggy and slow. So if you still want to use eclipse better stick to some older version. And finally i am able to found how to enable auto-complete in eclipse. Below is a small tutorial.
Eclipse -> Preference - > Java -> Editor -> Content Assist -> Auto Activation
Now put following in the three given boxes
Auto Activation delay(ms) - 0
Auto activation triggers for java - .(abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
Auto activation triggers for javadoc - @#
You are now good to go. Happy coding.
EDIT
As now Google has adopted Intellij for their own Android dev tool, there is no question now about which one is better. Intellij is far far better than eclipse. And i switched back to Intellij and it feels like i am back home!! :D
You're most likely looking at using a flash/silverlight/activeX control. The <input type="file" />
control doesn't handle that.
If you don't mind the user selecting a file as a means to getting its directory, you may be able to bind to that control's change
event then strip the filename portion and save the path somewhere--but that's about as good as it gets.
Keep in mind that webpages are designed to interact with servers. Nothing about providing a local directory to a remote server is "typical" (a server can't access it so why ask for it?); however files are a means to selectively passing information.
Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80
(there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80
. Make sure that View ? Word Wrap
is selected.
To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User
and use any of the following rules:
{
// set vertical rulers in specified columns.
// Use "rulers": [80] for just one ruler
// default value is []
"rulers": [80, 100, 120],
// turn on word wrap for source and text
// default value is "auto", which means off for source and on for text
"word_wrap": true,
// set word wrapping at this column
// default value is 0, meaning wrapping occurs at window width
"wrap_width": 80
}
These settings can also be used in a .sublime-project
file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings
file if you only want them to apply to files written in a certain language (Python.sublime-settings
vs. JavaScript.sublime-settings
, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User
.
As always, if you have multiple entries in your settings file, separate them with commas ,
except for after the last one. The entire content should be enclosed in curly braces { }
. Basically, make sure it's valid JSON.
If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.
Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0
and O
(digit zero and capital letter oh) and 1
and l
(digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).
The docs mention train_test_split is just a convenience function on top of shuffle split.
I just rearranged some of their code to make my own example. Note the actual solution is the middle block of code. The rest is imports, and setup for a runnable example.
from sklearn.model_selection import ShuffleSplit
from sklearn.utils import safe_indexing, indexable
from itertools import chain
import numpy as np
X = np.reshape(np.random.randn(20),(10,2)) # 10 training examples
y = np.random.randint(2, size=10) # 10 labels
seed = 1
cv = ShuffleSplit(random_state=seed, test_size=0.25)
arrays = indexable(X, y)
train, test = next(cv.split(X=X))
iterator = list(chain.from_iterable((
safe_indexing(a, train),
safe_indexing(a, test),
train,
test
) for a in arrays)
)
X_train, X_test, train_is, test_is, y_train, y_test, _, _ = iterator
print(X)
print(train_is)
print(X_train)
Now I have the actual indexes: train_is, test_is
Maybe Math.floor(value * 100) / 100
? Beware that the values like 3.54
may be not exactly represented with a double
.
Thanks for the help everyone, rejecting the promise in .catch()
solved my issue:

.then(status)
.then(res => res.json())

});
};
}
function status(res) {
if (!res.ok) {
throw new Error(res.statusText);
}
return res;
}
I'm using this long time and it's very helpful for me, use as you like
Date.prototype.date=function() {
return this.getFullYear()+'-'+String(this.getMonth()+1).padStart(2, '0')+'-'+String(this.getDate()).padStart(2, '0')
}
Date.prototype.time=function() {
return String(this.getHours()).padStart(2, '0')+':'+String(this.getMinutes()).padStart(2, '0')+':'+String(this.getSeconds()).padStart(2, '0')
}
Date.prototype.dateTime=function() {
return this.getFullYear()+'-'+String(this.getMonth()+1).padStart(2, '0')+'-'+String(this.getDate()).padStart(2, '0')+' '+String(this.getHours()).padStart(2, '0')+':'+String(this.getMinutes()).padStart(2, '0')+':'+String(this.getSeconds()).padStart(2, '0')
}
Date.prototype.addTime=function(time) {
var time=time.split(":")
var rd=new Date(this.setHours(this.getHours()+parseInt(time[0])))
rd=new Date(rd.setMinutes(rd.getMinutes()+parseInt(time[1])))
return new Date(rd.setSeconds(rd.getSeconds()+parseInt(time[2])))
}
Date.prototype.addDate=function(time) {
var time=time.split("-")
var rd=new Date(this.setFullYear(this.getFullYear()+parseInt(time[0])))
rd=new Date(rd.setMonth(rd.getMonth()+parseInt(time[1])))
return new Date(rd.setDate(rd.getDate()+parseInt(time[2])))
}
Date.prototype.subDate=function(time) {
var time=time.split("-")
var rd=new Date(this.setFullYear(this.getFullYear()-parseInt(time[0])))
rd=new Date(rd.setMonth(rd.getMonth()-parseInt(time[1])))
return new Date(rd.setDate(rd.getDate()-parseInt(time[2])))
}
and then just:
new Date().date()
which returns current date in 'MySQL format'
for add time is
new Date().addTime('0:30:0')
which will add 30 minutes.... and so on
Functions mysql_
are not supported any longer and have been removed in PHP 7
. You must use mysqli_
instead. However it's not recommended method now. You should consider PDO
with better security solutions.
$result = mysqli_query($con, "SELECT option_value FROM wp_10_options WHERE option_name='homepage' LIMIT 1");
$row = mysqli_fetch_assoc($result);
echo $row['option_value'];
While not exactly renaming, dplyr::select_all()
can be used to reformat column names. This example replaces spaces and periods with an underscore and converts everything to lower case:
iris %>%
select_all(~gsub("\\s+|\\.", "_", .)) %>%
select_all(tolower) %>%
head(2)
sepal_length sepal_width petal_length petal_width species
1 5.1 3.5 1.4 0.2 setosa
2 4.9 3.0 1.4 0.2 setosa
With sqldf
:
# Example by Mehdi Nellen
a <- c(rep("A", 3), rep("B", 3), rep("C",2))
b <- c(1,1,2,4,1,1,2,2)
df <-data.frame(a,b)
Solution:
library(sqldf)
sqldf('SELECT DISTINCT * FROM df')
Output:
a b
1 A 1
2 A 2
3 B 4
4 B 1
5 C 2
If you're needing something simple, would this fit the bill?
Map<K, V> myCache = Collections.synchronizedMap(new WeakHashMap<K, V>());
It wont save to disk, but you said you wanted simple...
Links:
(As Adam commented, synchronising a map has a performance hit. Not saying the idea doesn't have hairs on it, but would suffice as a quick and dirty solution.)
How about:
if('functionName' in Obj){
//code
}
e.g.
var color1 = new String("green");
"length" in color1 // returns true
"indexOf" in color1 // returns true
"blablabla" in color1 // returns false
or as for your case:
if('onChange' in me){
//code
}
See MDN docs.
The C++ Standard reads in section 7.3.1.1 Unnamed namespaces, paragraph 2:
The use of the static keyword is deprecated when declaring objects in a namespace scope, the unnamed-namespace provides a superior alternative.
Static only applies to names of objects, functions, and anonymous unions, not to type declarations.
The decision to deprecate this use of the static
keyword (affecting visibility of a variable declaration in a translation unit) has been reversed (ref). In this case using a static
or an unnamed namespace
are back to being essentially two ways of doing the exact same thing. For more discussion please see this SO question.
Unnamed namespace
's still have the advantage of allowing you to define translation-unit-local types. Please see this SO question for more details.
Credit goes to Mike Percy for bringing this to my attention.
After reading all the posts here, i settled on the consolidated solution of Marko Avlijaš. However, it did not solve all of my issues.
In our environment we have a Windows Service which is scheduled to run hundreds of different .bat .cmd .exe,... etc. files which have accumulated over the years and were written by many different people and in different styles. We have no control over the writing of the programs & scripts, we are just responsible for scheduling, running, and reporting on success/failure.
So i tried pretty much all of the suggestions here with different levels of success. Marko's answer was almost perfect, but when run as a service, it didnt always capture stdout. I never got to the bottom of why not.
The only solution we found that works in ALL our cases is this : http://csharptest.net/319/using-the-processrunner-class/index.html
Another idea I came across was assigning an id
to the <script>
element and passing the arguments as data-*
attributes. The resulting <script>
tag would look something like this:
<script id="helper" data-name="helper" src="helper.js"></script>
The script could then use the id to programmatically locate itself and parse the arguments. Given the previous <script>
tag, the name could be retrieved like this:
var name = document.getElementById("helper").getAttribute("data-name");
We get name
= helper
You could use the SQL%ROWCOUNT
Oracle variable:
UPDATE table1
SET field2 = value2,
field3 = value3
WHERE field1 = value1;
IF (SQL%ROWCOUNT = 0) THEN
INSERT INTO table (field1, field2, field3)
VALUES (value1, value2, value3);
END IF;
It would be easier just to determine if your primary key (i.e. field1
) has a value and then perform an insert or update accordingly. That is, if you use said values as parameters for a stored procedure.

var xDiff = xDown - xUp;
var yDiff = yDown - yUp;
if(Math.abs( xDiff )+Math.abs( yDiff )>150){ //to deal with to short swipes
if ( Math.abs( xDiff ) > Math.abs( yDiff ) ) {/*most significant*/

};
The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):
Mikhail,
The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.
Good luck with your implementation.
Arrays
in Java have a defined size, you cannot change it later by adding or removing elements (you can read some basics here).
Instead, use a List
:
ArrayList<String> mylist = new ArrayList<String>();
mylist.add(mystring); //this adds an element to the list.
Of course, if you know beforehand how many strings you are going to put in your array, you can create an array of that size and set the elements by using the correct position:
String[] myarray = new String[numberofstrings];
myarray[23] = string24; //this sets the 24'th (first index is 0) element to string24.
I think Microsoft guide for ASP.NET Identity is a good start.
Note:
If you do not use AccountController and wan't to reset your password, use Request.GetOwinContext().GetUserManager<ApplicationUserManager>();
. If you dont have the same OwinContext you need to create a new DataProtectorTokenProvider
like the one OwinContext
uses. By default look at App_Start -> IdentityConfig.cs
. Should look something like new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
.
Could be created like this:
Without Owin:
[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset()
{
var db = new ApplicationDbContext();
var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
var provider = new DpapiDataProtectionProvider("SampleAppName");
manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
provider.Create("SampleTokenName"));
var email = "[email protected]";
var user = new ApplicationUser() { UserName = email, Email = email };
var identityUser = manager.FindByEmail(email);
if (identityUser == null)
{
manager.Create(user);
identityUser = manager.FindByEmail(email);
}
var token = manager.GeneratePasswordResetToken(identityUser.Id);
return Ok(HttpUtility.UrlEncode(token));
}
[HttpGet]
[AllowAnonymous]
[Route("testReset")]
public IHttpActionResult TestReset(string token)
{
var db = new ApplicationDbContext();
var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(db));
var provider = new DpapiDataProtectionProvider("SampleAppName");
manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(
provider.Create("SampleTokenName"));
var email = "[email protected]";
var identityUser = manager.FindByEmail(email);
var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
return Ok(result);
}
With Owin:
[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin()
{
var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();
var email = "[email protected]";
var user = new ApplicationUser() { UserName = email, Email = email };
var identityUser = manager.FindByEmail(email);
if (identityUser == null)
{
manager.Create(user);
identityUser = manager.FindByEmail(email);
}
var token = manager.GeneratePasswordResetToken(identityUser.Id);
return Ok(HttpUtility.UrlEncode(token));
}
[HttpGet]
[AllowAnonymous]
[Route("testResetWithOwin")]
public IHttpActionResult TestResetWithOwin(string token)
{
var manager = Request.GetOwinContext().GetUserManager<ApplicationUserManager>();
var email = "[email protected]";
var identityUser = manager.FindByEmail(email);
var valid = Task.Run(() => manager.UserTokenProvider.ValidateAsync("ResetPassword", token, manager, identityUser)).Result;
var result = manager.ResetPassword(identityUser.Id, token, "TestingTest1!");
return Ok(result);
}
The DpapiDataProtectionProvider
and DataProtectorTokenProvider
needs to be created with the same name for a password reset to work. Using Owin for creating the password reset token and then creating a new DpapiDataProtectionProvider
with another name won't work.
Code that I use for ASP.NET Identity:

<add key="AllowedHosts" value="example.com,example2.com" />

I had the same problem. Just after enabling Internet Virtualization from BIOS. After that let the system boot and install HAXM once again. Now emulator will run faster than before and HAXM will work. Enjoy!!
The table normally contains multiple rows. Use a loop and use row.Field<string>(0)
to access the value of each row.
foreach(DataRow row in dt.Rows)
{
string file = row.Field<string>("File");
}
You can also access it via index:
foreach(DataRow row in dt.Rows)
{
string file = row.Field<string>(0);
}
If you expect only one row, you can also use the indexer of DataRowCollection
:
string file = dt.Rows[0].Field<string>(0);
Since this fails if the table is empty, use dt.Rows.Count
to check if there is a row:
if(dt.Rows.Count > 0)
file = dt.Rows[0].Field<string>(0);
Ruby(1.9+)
#!/usr/bin/env ruby
Dir["*"].each do |file|
h=Hash.new(0)
open(file).each do |row|
row.chomp.split("\t").each do |w|
h[ w ] += 1
end
end
h.sort{|a,b| b[1]<=>a[1] }.each{|x,y| print "#{x}:#{y}\n" }
end
The subject of the certificate is the entity its public key is associated with (i.e. the "owner" of the certificate).
As RFC 5280 says:
The subject field identifies the entity associated with the public key stored in the subject public key field. The subject name MAY be carried in the subject field and/or the subjectAltName extension.
X.509 certificates have a Subject (Distinguished Name) field and can also have multiple names in the Subject Alternative Name extension.
The Subject DN is made of multiple relative distinguished names (RDNs) (themselves made of attribute assertion values) such as "CN=yourname" or "O=yourorganization".
In the context of the article you're linking to, the subject would be the user/owner of the cert.
Alternatively, if you have Node.js installed, you can use the following command:
npx degit GIT_REPO
npx
comes with Node, and it allows you to run binary node-based packages without installing them first (alternatively, you can first install degit
globally using npm i -g degit
).
Degit is a tool created by Rich Harris, the creator of Svelte and Rollup, which he uses to quickly create a new project by cloning a repository without keeping the git folder. But it can also be used to clone any repo once...
If you compute modulo a power of two, using bitwise AND is simpler and generally faster than performing division. If b
is a power of two, a % b == a & (b - 1)
.
For example, let's take a value in register EAX, modulo 64.
The simplest way would be AND EAX, 63
, because 63 is 111111 in binary.
The masked, higher digits are not of interest to us. Try it out!
Analogically, instead of using MUL or DIV with powers of two, bit-shifting is the way to go. Beware signed integers, though!
You can use sudo apt remove ruby
If you know the viewport angle of the camera, you can use the height in pixels to determine the angle from the top to bottom of the object. Then, using the distance and arctangent calculate the height:
height = arctan(angle) * distance
To find the viewport angle, point the camera at something which is of known height, and make it exactly fill the screen. For example, point it at a ruler, and make it just far enough away that you can only barely see the ends of the ruler. Measure the distance from the camera, and then your total viewport angle is
viewportAngle = tan(ruler_length / distance)
Then, suppose your camera is 480px tall (cheap webcam), and the view angle is 20°. If you have an object onscreen which is 240px tall, then its angle is 10°. If you know it's 2 feet away, you would say 2 feet * arctan(10°) = ~4.1 inches
tall. (I think... it's 2am so this may be a little off)
This code will add an event listener to the default local Inbox, then take some action on incoming emails. You need to add that action in the code below.
Private WithEvents Items As Outlook.Items
Private Sub Application_Startup()
Dim olApp As Outlook.Application
Dim objNS As Outlook.NameSpace
Set olApp = Outlook.Application
Set objNS = olApp.GetNamespace("MAPI")
' default local Inbox
Set Items = objNS.GetDefaultFolder(olFolderInbox).Items
End Sub
Private Sub Items_ItemAdd(ByVal item As Object)
On Error Goto ErrorHandler
Dim Msg As Outlook.MailItem
If TypeName(item) = "MailItem" Then
Set Msg = item
' ******************
' do something here
' ******************
End If
ProgramExit:
Exit Sub
ErrorHandler:
MsgBox Err.Number & " - " & Err.Description
Resume ProgramExit
End Sub
After pasting the code in ThisOutlookSession
module, you must restart Outlook.
You can also "fix" this by replacing the image with its inline Base64 representation:
Useful, when you do not intend to publish the page on the web, but instead use it on local machines only. img.src= "data:image/gif;base64,R0lGODlhCwALAIAAAAAA3pn/ZiH5BAEAAAEALAAAAAALAAsAAAIUhA+hkcuO4lmNVindo7qyrIXiGBYAOw==";
What do you mean by merging? JSON objects are key-value data structure. What would be a key and a value in this case? I think you need to create new directory and populate it with old data:
d = {}
d["new_key"] = jsonStringA[<key_that_you_did_not_mention_here>] + \
jsonStringB["timestamp_in_ms"]
Merging method is obviously up to you.
I think an option for your purposes is git log --online --decorate
. This lets you know the checked commit, and the top commits for each branch that you have in your story line. By doing this, you have a nice view on the structure of your repo and the commits associated to a specific branch. I think reading this might help.
instead of using explode, try preg_split: http://www.php.net/manual/en/function.preg-split.php

Month::getDisplayName
Since Java 8, use the Month
enum. The getDisplayName
method automatically localizes the name of the month.
Pass:
TextStyle
to determine how long or how abbreviated.Locale
to specify the human language used in translation, and the cultural norms used for abbreviation, punctuation, etc.Example:
public static String getMonthStandaloneName(Month month) {
return month.getDisplayName(
TextStyle.FULL_STANDALONE,
Locale.getDefault()
);
}
As other said, the comment in XML are like this
<!-- this is a comment -->
Notice that they can span on multiple lines
<!--
This is a comment
on multiple lines

But they cannot be nested
<!-- This <!-- is a comment --> This is not -->
Also you cannot use them inside tags

just clean project and then sync your project with gradle file.
Did you try with strip() :
listOfNum = ['231512-n','1209123100000-n00000','alphanumeric0000', 'alphanumeric']
print [item.strip('0') for item in listOfNum]
>>> ['231512-n', '1209123100000-n', 'alphanumeric', 'alphanumeric']
answer to your question is simple order is not a object make it an array. var order = new Array(); order.push(/item to push/); when ever this error appears just check the left of which property the error is in this case it is push which is order[] so it is undefined.
Why not to try simple (but powerful) html()
method:
iElement.html('<svg width="600" height="100" class="svg"></svg>');
Or append
as an alternative:
iElement.append('<svg width="600" height="100" class="svg"></svg>');
And , of course , more cleaner way:
var svg = angular.element('<svg width="600" height="100" class="svg"></svg>');
iElement.append(svg);
Here is an example which I use in my source code. I am getting key and value from Dictionary from element 0 to number of elements in my Dictionary. Then I fill my string[] array which I send as a parameter after in my function which accept only params string[]
Dictionary<string, decimal> listKomPop = addElements();
int xpopCount = listKomPop.Count;
if (xpopCount > 0)
{
string[] xpostoci = new string[xpopCount];
for (int i = 0; i < xpopCount; i++)
{
/* here you have key and value element */
string key = listKomPop.Keys.ElementAt(i);
decimal value = listKomPop[key];
xpostoci[i] = value.ToString();
}
...
This solution works with SortedDictionary also.
function stripTrailingSlash(text) {
return text
.split('/')
.filter(Boolean)
.join('/');
}
another solution.
if you look to support old version pre lolipop
use the same xml code with some changes
instead of normal ImageView --> AppCompatImageView
instead of android:src --> app:srcCompat
here is example
<android.support.v7.widget.AppCompatImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:id="@+id/button"
app:srcCompat="@drawable/ic_more_vert_24dp"
android:tint="@color/primary" />
dont forget update your gradle as @ Sayooj Valsan mention
// Gradle Plugin 2.0+ android { defaultConfig { vectorDrawables.useSupportLibrary = true } } compile 'com.android.support:design:23.4.0'
Notice To any one use vector dont ever ever never give your vector reference to color like this one android:fillColor="@color/primary"
give its hex value .
Sometimes a lot of troubles with it. In attribute value of datapicker data is 28-06-2014, but datepicker is show or today or nothing. I decided it in a such way:
<input type="text" class="form-control datepicker" data-value="<?= date('d-m-Y', (!$event->date ? time() : $event->date)) ?>" value="<?= date('d-m-Y', (!$event->date ? time() : $event->date)) ?>" />
I added to the input of datapicker attribute data-value, because if call jQuery(this).val() OR jQuery(this).attr('value') - nothing works. I decided init in cycle each datapicker and take its value from attribute data-value:
$("form .datepicker").each(function() {
var time = jQuery(this).data('value');
time = time.split('-');
$(this).datepicker('setDate', new Date(time[2], time[1], time[0], 0, 0, 0));
});
and it is works fine =)
print('<tr><td>%04d</td>' % (i+1), file=Html_file)
How about the following 3 statements?
-- change to your schema
ALTER SESSION SET CURRENT_SCHEMA=yourSchemaName;
-- check current schema
SELECT SYS_CONTEXT('USERENV','CURRENT_SCHEMA') FROM DUAL;
-- generate drop table statements
SELECT 'drop table ', table_name, 'cascade constraints;' FROM ALL_TABLES WHERE OWNER = 'yourSchemaName';
COPY the RESULT and PASTE and RUN.
POSIX sh doesn't understand ==
for string equality, as that is a bash-ism. Use =
instead.
The other people saying that brackets aren't supported by sh are wrong, btw.
If you just want to check the value is in Range, use this:
MIN_VALUE = 1;
MAX_VALUE = 100;
$customValue = min(MAX_VALUE,max(MIN_VALUE,$customValue)));
Since the above only works for python 2.x for python 3.x (specifically 3.5) is similar but with a slight modification:
import readline
for i in range(readline.get_current_history_length()):
print (readline.get_history_item(i + 1))
note the extra ()
(using shell scripts to parse .python_history or using python to modify the above code is a matter of personal taste and situation imho)
Instead of using a bat file, you can simply create a Scheduled Task. Most of the time you define just one action. In this case, create two actions with the NET
command. The first one to stop the service, the second one to start the service. Give them a STOP
and START
argument, followed by the service name.
In this example we restart the Printer Spooler service.
NET STOP "Print Spooler"
NET START "Print Spooler"
Note: unfortunately NET RESTART <service name>
does not exist.
The <img>
element is empty — it doesn't have an end tag.
If the image is a background image, use CSS. If it is a content image, then set position: relative
on a container, then absolutely position the image and/or text within it.
The accepted answer doesn't work if some package vendors it's own copy of urllib3, in which case this will still work:
import warnings
warnings.filterwarnings('ignore', message='Unverified HTTPS request')
You can also use map
(which is a very useful function to get to know anyway):
sd = dict(map(lambda k: (k, l.get(k, None)), l))
Example:
large_dictionary = {'a1':123, 'a2':45, 'a3':344}
list_of_keys = ['a1', 'a3']
small_dictionary = dict(map(lambda key: (key, large_dictionary.get(key, None)), list_of_keys))
PS: I borrowed the .get(key, None)
from a previous answer :)
As others has answer, the Request.Files is an HttpFileCollection that contains all the files that were posted, you only need to ask that object for the file like this:
Request.Files["myFile"]
But what happen when there are more than one input mark-up with the same attribute name:
Select file 1 <input type="file" name="myFiles" />
Select file 2 <input type="file" name="myFiles" />
On the server side the previous code Request.Files["myFile"] only return one HttpPostedFile object instead of the two files. I have seen on .net 4.5 an extension method called GetMultiple but for prevoious versions it doesn't exists, for that matter i propose the extension method as:
public static IEnumerable<HttpPostedFile> GetMultiple(this HttpFileCollection pCollection, string pName)
{
for (int i = 0; i < pCollection.Count; i++)
{
if (pCollection.GetKey(i).Equals(pName))
{
yield return pCollection.Get(i);
}
}
}
This extension method will return all the HttpPostedFile objects that have the name "myFiles" in the HttpFileCollection if any exists.
protected void btnExportExcel_Click(object sender, EventArgs e)
{
DataTable _datatable = new DataTable();
for (int i = 0; i < grdReport.Columns.Count; i++)
{
_datatable.Columns.Add(grdReport.Columns[i].ToString());
}
foreach (GridViewRow row in grdReport.Rows)
{
DataRow dr = _datatable.NewRow();
for (int j = 0; j < grdReport.Columns.Count; j++)
{
if (!row.Cells[j].Text.Equals(" "))
dr[grdReport.Columns[j].ToString()] = row.Cells[j].Text;
}
_datatable.Rows.Add(dr);
}
ExportDataTableToExcel(_datatable);
}
If you are only interested into finding the position see @Pablo's answer.
pos = myArray.map(function(e) { return e.hello; }).indexOf('stevie');
However, if you are looking forward to finding the element (i.e. if you were thinking of doing something like this myArray[pos]
), there is a more efficient one-line way to do it, using filter
.
element = myArray.filter((e) => e.hello === 'stevie')[0];

I re-installed the ODBC connector msi and re-installed mySQL directly (aside from xampp) and it now works. It was a connector problem I think, as SHOW DATABASES wasn't actually showing my databases at all.
My 'root' login wasn't getting access to the DB, which made it seem like it had limited priviliges but it actually wasn't connected properly.
i want to post my solution here which was done AngularJS, ASP.NET MVC. The code illustrates how to download file with authentication.
WebApi method along with helper class:
[RoutePrefix("filess")]
class FileController: ApiController
{
[HttpGet]
[Route("download-file")]
[Authorize(Roles = "admin")]
public HttpResponseMessage DownloadDocument([FromUri] int fileId)
{
var file = "someFile.docx"// asking storage service to get file path with id
return Request.ReturnFile(file);
}
}
static class DownloadFIleFromServerHelper
{
public static HttpResponseMessage ReturnFile(this HttpRequestMessage request, string file)
{
var result = request.CreateResponse(HttpStatusCode.OK);
result.Content = new StreamContent(new FileStream(file, FileMode.Open, FileAccess.Read));
result.Content.Headers.Add("x-filename", Path.GetFileName(file)); // letters of header names will be lowercased anyway in JS.
result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
result.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = Path.GetFileName(file)
};
return result;
}
}
Web.config file changes to allow sending file name in custom header.
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Methods" value="POST,GET,PUT,PATCH,DELETE,OPTIONS" />
<add name="Access-Control-Allow-Headers" value="Authorization,Content-Type,x-filename" />
<add name="Access-Control-Expose-Headers" value="Authorization,Content-Type,x-filename" />
<add name="Access-Control-Allow-Origin" value="*" />
Angular JS Service Part:
function proposalService($http, $cookies, config, FileSaver) {
return {
downloadDocument: downloadDocument
};
function downloadFile(documentId, errorCallback) {
$http({
url: config.apiUrl + "files/download-file?documentId=" + documentId,
method: "GET",
headers: {
"Content-type": "application/json; charset=utf-8",
"Authorization": "Bearer " + $cookies.get("api_key")
},
responseType: "arraybuffer"
})
.success( function(data, status, headers) {
var filename = headers()['x-filename'];
var blob = new Blob([data], { type: "application/octet-binary" });
FileSaver.saveAs(blob, filename);
})
.error(function(data, status) {
console.log("Request failed with status: " + status);
errorCallback(data, status);
});
};
};
Module dependency for FileUpload: angular-file-download (gulp install angular-file-download --save). Registration looks like below.
var app = angular.module('cool',
[
...
require('angular-file-saver'),
])
. // other staff.
>>> sorted(['Some', 'words', 'sort', 'differently'], key=lambda word: word.lower())
Actually, above codes can be:
>>> sorted(['Some','words','sort','differently'],key=str.lower)
According to https://docs.python.org/2/library/functions.html?highlight=sorted#sorted, key specifies a function of one argument that is used to extract a comparison key from each list element: key=str.lower. The default value is None (compare the elements directly).
$date = '2014-02-25';
date('D', strtotime($date));
There are several problems in your code.
First the big ones:
You are creating a new figure and a new axes in every iteration of your loop ?
put fig = plt.figure
and ax = fig.add_subplot(1,1,1)
outside of the loop.
Don't use the Locators. Call the functions ax.set_xticks()
and ax.grid()
with the correct keywords.
With plt.axes()
you are creating a new axes again. Use ax.set_aspect('equal')
.
The minor things:
You should not mix the MATLAB-like syntax like plt.axis()
with the objective syntax.
Use ax.set_xlim(a,b)
and ax.set_ylim(a,b)
This should be a working minimal example:
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
# Major ticks every 20, minor ticks every 5
major_ticks = np.arange(0, 101, 20)
minor_ticks = np.arange(0, 101, 5)
ax.set_xticks(major_ticks)
ax.set_xticks(minor_ticks, minor=True)
ax.set_yticks(major_ticks)
ax.set_yticks(minor_ticks, minor=True)
# And a corresponding grid
ax.grid(which='both')
# Or if you want different settings for the grids:
ax.grid(which='minor', alpha=0.2)
ax.grid(which='major', alpha=0.5)
plt.show()
Output is this:
What can you do if you need to make a change to a file, but don’t know the file’s encoding? If you know the encoding is ASCII-compatible and only want to examine or modify the ASCII parts, you can open the file with the surrogateescape error handler:
with open(fname, 'r', encoding="ascii", errors="surrogateescape") as f:
data = f.read()
Look at the r.status_code
attribute:
if r.status_code == 404:
# A 404 was issued.
Demo:
>>> import requests
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.status_code
404
If you want requests
to raise an exception for error codes (4xx or 5xx), call r.raise_for_status()
:
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.raise_for_status()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "requests/models.py", line 664, in raise_for_status
raise http_error
requests.exceptions.HTTPError: 404 Client Error: NOT FOUND
>>> r = requests.get('http://httpbin.org/status/200')
>>> r.raise_for_status()
>>> # no exception raised.
You can also test the response object in a boolean context; if the status code is not an error code (4xx or 5xx), it is considered ‘true’:
if r:
# successful response
If you want to be more explicit, use if r.ok:
.
From the grep(1)
man page:
-l, --files-with-matches Suppress normal output; instead print the name of each input file from which output would normally have been printed. The scanning will stop on the first match. (-l is specified by POSIX.)
private float distanceFrom_in_Km(float lat1, float lng1, float lat2, float lng2) {
if (lat1== null || lng1== null || lat2== null || lng2== null)
{
return null;
}
double earthRadius = 6371000; //meters
double dLat = Math.toRadians(lat2-lat1);
double dLng = Math.toRadians(lng2-lng1);
double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)) *
Math.sin(dLng/2) * Math.sin(dLng/2);
double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
float dist = (float) (earthRadius * c);
return dist;
}
First, note that the question presents an incorrect initialization of an aware datetime object:
>>> local_time=datetime.datetime(2010, 4, 27, 12, 0, 0, 0,
... tzinfo=pytz.timezone('Israel'))
creates an invalid instance. One can see the problem by computing the UTC offset of the resulting object:
>>> print(local_time.utcoffset())
2:21:00
(Note the result which is an odd fraction of an hour.)
To initialize an aware datetime properly using pytz one should use the localize()
method as follows:
>>> local_time=pytz.timezone('Israel').localize(datetime.datetime(2010, 4, 27, 12))
>>> print(local_time.utcoffset())
3:00:00
Now, if you require a local pytz timezone as the new tzinfo, you should use the tzlocal package as others have explained, but if all you need is an instance with a correct local time zone offset and abbreviation then tarting with Python 3.3, you can call the astimezone()
method with no arguments to convert an aware datetime
instance to your local timezone:
>>> local_time.astimezone().strftime('%Y-%m-%d %H:%M %Z %z')
'2010-04-27 05:00 EDT -0400'
a = np.arange(18).reshape(9,2)
b = a.reshape(3,3,2).swapaxes(0,2)
# a:
array([[ 0, 1],
[ 2, 3],
[ 4, 5],
[ 6, 7],
[ 8, 9],
[10, 11],
[12, 13],
[14, 15],
[16, 17]])
# b:
array([[[ 0, 6, 12],
[ 2, 8, 14],
[ 4, 10, 16]],
[[ 1, 7, 13],
[ 3, 9, 15],
[ 5, 11, 17]]])
You can use:
const sha1 = require('sha1');
const crypt = sha1('Text');
console.log(crypt);
For install:
sudo npm install -g sha1
npm install sha1 --save
string cmdArguments = $@"/k svn log --trust-server-cert --non-interactive ""{servidor}"" --username alex --password alex -r {numeroRevisao}";
ProcessStartInfo cmd = new ProcessStartInfo("cmd.exe", cmdArguments);
cmd.CreateNoWindow = true;
cmd.RedirectStandardOutput = true;
cmd.RedirectStandardError = true;
cmd.WindowStyle = ProcessWindowStyle.Hidden;
cmd.UseShellExecute = false;
Process reg = Process.Start(cmd);
string output = "";
using (System.IO.StreamReader myOutput = reg.StandardOutput)
{
output += myOutput.ReadToEnd();
}
using (System.IO.StreamReader myError = reg.StandardError)
{
output += myError.ReadToEnd();
}
return output;
The closest thing would be the bind function:
$('#foo').bind('click', function() {
alert('User clicked on "foo."');
});
Generate a random password of length 8 to 32 characters with at least 1 lower case, 1 upper case, 1 number, 1 spl char (!@$&)
function getRandomUpperCase() {
return String.fromCharCode( Math.floor( Math.random() * 26 ) + 65 );
}
function getRandomLowerCase() {
return String.fromCharCode( Math.floor( Math.random() * 26 ) + 97 );
}
function getRandomNumber() {
return String.fromCharCode( Math.floor( Math.random() * 10 ) + 48 );
}
function getRandomSymbol() {
// const symbol = '!@#$%^&*(){}[]=<>/,.|~?';
const symbol = '!@$&';
return symbol[ Math.floor( Math.random() * symbol.length ) ];
}
const randomFunc = [ getRandomUpperCase, getRandomLowerCase, getRandomNumber, getRandomSymbol ];
function getRandomFunc() {
return randomFunc[Math.floor( Math.random() * Object.keys(randomFunc).length)];
}
function generatePassword() {
let password = '';
const passwordLength = Math.random() * (32 - 8) + 8;
for( let i = 1; i <= passwordLength; i++ ) {
password += getRandomFunc()();
}
//check with regex
const regex = /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,32}$/
if( !password.match(regex) ) {
password = generatePassword();
}
return password;
}
console.log( generatePassword() );
In my case, cleaning and rebuilding the project resolved the problem.
This has been fully answered here.

Use this react native library
To install
npm install react-native-htmlview --save
Basic Usage
import React from 'react';
import HTMLView from 'react-native-htmlview';
class App extends React.Component {
render() {
const htmlContent = 'This is a sentence <b>with</b> one word in bold';
return (
<HTMLView
value={htmlContent}
/> );
}
}
Supports almost all html tags.

I follow Jason's step, but not works.
And then I find the WTP Update site http://download.eclipse.org/webtools/updates/.
Help -> Install new software -> Add > WTP:http://download.eclipse.org/webtools/updates/ -> OK
Then Help -> Check for update
, just works, I don't know whether Jason's affect this .
This is similar to @Anon's answer in that it keeps the rest of the string's case intact, without the need for the re module.
def sliceindex(x):
i = 0
for c in x:
if c.isalpha():
i = i + 1
return i
i = i + 1
def upperfirst(x):
i = sliceindex(x)
return x[:i].upper() + x[i:]
x = '0thisIsCamelCase'
y = upperfirst(x)
print(y)
# 0ThisIsCamelCase
As @Xan pointed out, the function could use more error checking (such as checking that x is a sequence - however I'm omitting edge cases to illustrate the technique)
Updated per @normanius comment (thanks!)
Thanks to @GeoStoneMarten in pointing out I didn't answer the question! -fixed that
Here's the one liner.
${empty value?'value is empty or null':'value is NOT empty or null'}
- Create a Class
with public static final
fields.
- And then you can access these fields from any class using the Class_Name.Field_Name
.
- You can declare the class
as final
, so that the class
can't be extended(Inherited) and modify....
I had the same problem but solved it when I realized that I didn't compile it with the correct casing. You may have been doing
javac Weatherarray.java

ASCII-8BIT is Ruby's description for characters above the normal 0-0x7f ASCII character-set, and that are single-byte characters. Typically that would be something like ISO-8859-1, or one of its siblings.
If you can identify which character is causing the problem, then you can tell Ruby 1.9.2 to convert between the character set of that character to UTF-8.
James Grey wrote a series of blogs talking about these sort of problems and how to deal with them. I'd recommend going through them.
incompatible character encodings: ASCII-8BIT and UTF-8
That typically happens because you are trying to concatenate two strings, and one contains characters that do not map to the character-set of the other string. There are characters in ISO-8859-1 that do not have equivalents in UTF-8, and vice-versa and how to handle string joining with those incompatibilities requires the programmer to step in.
Simply put:
SELECT *
FROM TABLE_NAME
WHERE
dob > '1/21/2012'
Where 1/21/2012 is the date and you want all data, including that date.
SELECT *
FROM TABLE_NAME
WHERE
dob BETWEEN '1/21/2012' AND '2/22/2012'
Use a between if you're selecting time between two dates

You should generally NOT ignore the exception. Take a look at the following paper:
Don't swallow interrupts
Sometimes throwing InterruptedException is not an option, such as when a task defined by Runnable calls an interruptible method. In this case, you can't rethrow InterruptedException, but you also do not want to do nothing. When a blocking method detects interruption and throws InterruptedException, it clears the interrupted status. If you catch InterruptedException but cannot rethrow it, you should preserve evidence that the interruption occurred so that code higher up on the call stack can learn of the interruption and respond to it if it wants to. This task is accomplished by calling interrupt() to "reinterrupt" the current thread, as shown in Listing 3. At the very least, whenever you catch InterruptedException and don't rethrow it, reinterrupt the current thread before returning.
public class TaskRunner implements Runnable { private BlockingQueue<Task> queue; public TaskRunner(BlockingQueue<Task> queue) { this.queue = queue; } public void run() { try { while (true) { Task task = queue.take(10, TimeUnit.SECONDS); task.execute(); } } catch (InterruptedException e) { // Restore the interrupted status Thread.currentThread().interrupt(); } } }

I realize that this is an old question, but one scenario where RabbitMQ might be a better choice is when dealing with data redaction.
With RabbitMQ, by default once the message has been consumed, it's deleted. With Kafka, by default, messages are kept for a week. It's common to set this to a much longer time, or even to never delete them.
While both products can be configured to retain (or not retain) messages, if CCPA or GDPR compliance is a concern, I'd go with RabbitMQ.
In my case the reason was fairly trivial.
I had known that the SSL verification had worked until a few days earlier, and was infact working on a different machine.
My next step was to compare the certificate contents and size between the machine on which verification was working, and the one on which it was not.
This quickly led to me determining that the Certificate on the 'incorrectly' working machine was not good, and once I replaced it with the 'good' cert, everything was fine.
Not really an answer, but just a note about ->change()
:
Only the following column types can be "changed": bigInteger, binary, boolean, date, dateTime, dateTimeTz, decimal, integer, json, longText, mediumText, smallInteger, string, text, time, unsignedBigInteger, unsignedInteger and unsignedSmallInteger.
https://laravel.com/docs/5.8/migrations#modifying-columns
If your column isn't one of these you will need to either drop the column or use the alter statement as mentioned in other answers.

Because you're using Python 3.1, you need to use the new Python 3.1 APIs.
Try:
urllib.request.urlopen('http://www.python.org/')
Alternately, it looks like you're working from Python 2 examples. Write it in Python 2, then use the 2to3 tool to convert it. On Windows, 2to3.py is in \python31\tools\scripts. Can someone else point out where to find 2to3.py on other platforms?
Edit
These days, I write Python 2 and 3 compatible code by using six.
from six.moves import urllib
urllib.request.urlopen('http://www.python.org')
Assuming you have six installed, that runs on both Python 2 and Python 3.
yes we can do this using nth-child like so
div:nth-child(n + 8) {
background: red;
}
This will make the 8th div child onwards become red. Hope this helps...
Also, if someone ever says "hey, they can't be done with styled using css, use JS!!!" doubt them immediately. CSS is extremely flexible nowadays
Example :: http://jsfiddle.net/uWrLE/1/
In the example the first 7 children are blue, then 8 onwards are red...
NSTimer has been renamed to Timer in Swift 4.2. this syntax will work in 4.2:

May works.
The variable set by varStatus
is a LoopTagStatus
object, not an int. Use:
<div id="divIDNo${theCount.index}">
To clarify:
${theCount.index}
starts counting at 0
unless you've set the begin
attribute${theCount.count}
starts counting at 1
Another reason for similar error message is trying to mock a final
method. One shouldn't attempt to mock final methods (see Final method mocking).
I have also confronted the error in a multi-threaded test. Answer by gna worked in that case.
To stop or start mysql on most linux systems the following should work:
/etc/init.d/mysqld stop
/etc/init.d/mysqld start
The other answers look good for accessing the mysql client from the command line.
Good luck!
That totally depends of what do you need exactly. If you just need to store and retrieve a token in order to use it in your http requests, i suggest you to simply create a service and use it in your whole project.
example of basic integration:
import {Injectable} from 'angular@core'
@Injectable()
export class TokenManager {
private tokenKey:string = 'app_token';
private store(content:Object) {
localStorage.setItem(this.tokenKey, JSON.stringify(content));
}
private retrieve() {
let storedToken:string = localStorage.getItem(this.tokenKey);
if(!storedToken) throw 'no token found';
return storedToken;
}
public generateNewToken() {
let token:string = '...';//custom token generation;
let currentTime:number = (new Date()).getTime() + ttl;
this.store({ttl: currentTime, token});
}
public retrieveToken() {
let currentTime:number = (new Date()).getTime(), token = null;
try {
let storedToken = JSON.parse(this.retrieve());
if(storedToken.ttl < currentTime) throw 'invalid token found';
token = storedToken.token;
}
catch(err) {
console.error(err);
}
return token;
}
}
However if you need to use the local storage more often, by using the stored values in your app views for example. You can use one of the libraries that provides a wrapper of the webstorages like you did with angular2-localstorage.
I created some months ago ng2-webstorage that should respond to your needs. It provides two ng2 services and two decorators to sync the webstorage's values and the service/component's attributes.
import {Component} from '@angular/core';
import {LocalStorageService, LocalStorage} from 'ng2-webstorage';
@Component({
selector: 'foo',
template: `
<section>{{boundValue}}</section>
<section><input type="text" [(ngModel)]="attribute"/></section>
<section><button (click)="saveValue()">Save</button></section>
`,
})
export class FooComponent {
@LocalStorage()
boundValue; // attribute bound to the localStorage
value;
constructor(private storage:LocalStorageService) {
this.localSt.observe('boundValue')// triggers the callback each time a new value is set
.subscribe((newValue) => console.log('new value', newValue));
}
saveValue() {
this.storage.store('boundValue', this.value); // store the given value
}
}
You can give the background image in css :
#canvas { background:url(example.jpg) }
it will show you canvas back ground image
function hex2rgb(hex) {
return ['0x' + hex[1] + hex[2] | 0, '0x' + hex[3] + hex[4] | 0, '0x' + hex[5] + hex[6] | 0];
}
This error has occurred when i was importing a project from Github. This happens as the project was of older version. Just try to delete these methods below from your root gradle.
android { compileSdkVersion 19 buildToolsVersion "19.1" }
then try again.
I hope it works.
var s = ",'first string','more','even more'";
var array = s.split(',').slice(1);
That's assuming the string you begin with is in fact a String, like you said, and not an Array of strings.
All commands must be executed while connected to the right database in the right database cluster. Make sure of it.
The user needs access to the database, obviously:
GRANT CONNECT ON DATABASE my_db TO my_user;
And (at least) the USAGE
privilege on the schema:
GRANT USAGE ON SCHEMA public TO my_user;
Or grant USAGE
on all custom schemas:
DO
$$
BEGIN
-- RAISE NOTICE '%', ( -- use instead of EXECUTE to see generated commands
EXECUTE (
SELECT string_agg(format('GRANT USAGE ON SCHEMA %I TO my_user', nspname), '; ')
FROM pg_namespace
WHERE nspname <> 'information_schema' -- exclude information schema and ...
AND nspname NOT LIKE 'pg\_%' -- ... system schemas
);
END
$$;
Then, all permissions for all tables (requires Postgres 9.0 or later).
And don't forget sequences (if any):
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO my_user;
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO my_user;
For older versions you could use the "Grant Wizard" of pgAdmin III (the default GUI).
There are some other objects, the manual for GRANT
has the complete list as of Postgres 12:
privileges on a database object (table, column, view, foreign table, sequence, database, foreign-data wrapper, foreign server, function, procedure, procedural language, schema, or tablespace)
But the rest is rarely needed. More details:

IE <= 9 doesn't support CORS. I've written a javascript that will automatically route those requests through a proxy. It's all 100% transparent (you just have to include my proxy and the script).

I have a similar problem. I open an error dialog when validation fails and it grabs the focus, just like Flugan shows it in his answer. The problem is that even if no element inside the dialog is tabbable, the dialog itself is still focused. Here is the original unminified code from jquery-ui-1.8.23\js\jquery.ui.dialog.js:
// set focus to the first tabbable element in the content area or the first button
// if there are no tabbable elements, set focus on the dialog itself
$(self.element.find(':tabbable').get().concat(
uiDialog.find('.ui-dialog-buttonpane :tabbable').get().concat(
uiDialog.get()))).eq(0).focus();
The comment is theirs!
This is really bad for me for several reasons. The most annoying thing is that the first reaction of the user is to hit the backspace to delete the last character, but instead (s)he is prompted to leave the page, because the backspace is hit outside an input control.
I found that the following workaround works pretty good for me:
jqueryFocus = $.fn.focus;
$.fn.focus = function (delay, fn) {
jqueryFocus.apply(this.filter(':not(.ui-dialog)'), arguments);
};
I had the same problem. My project layout looked like
\---super
\---thirdparty
+---mod1-root
| +---mod1-linux32
| \---mod1-win32
\---mod2-root
+---mod2-linux32
\---mod2-win32
In my case, I had a mistake in my pom.xmls at the modX-root-level. I had copied the mod1-root tree and named it mod2-root. I incorrectly thought I had updated all the pom.xmls appropriately; but in fact, mod2-root/pom.xml had the same group and artifact ids as mod1-root/pom.xml. After correcting mod2-root's pom.xml to have mod2-root specific maven coordinates my issue was resolved.
If you want multiple background images but don't want them to overlap, you can use this CSS:
body {
font-size: 13px;
font-family:Century Gothic, Helvetica, sans-serif;
color: #333;
text-align: center;
margin:0px;
padding: 25px;
}
#topshadow {
height: 62px
width:1030px;
margin: -62px
background-image: url(images/top-shadow.png);
}
#pageborders {
width:1030px;
min-height:100%;
margin:auto;
background:url(images/mid-shadow.png);
}
#bottomshadow {
margin:0px;
height:66px;
width:1030px;
background:url(images/bottom-shadow.png);
}
#page {
text-align: left;
margin:62px, 0px, 20px;
background-color: white;
margin:auto;
padding:0px;
width:1000px;
}
with this HTML structure:
<body
<?php body_class(); ?>>
<div id="topshadow">
</div>
<div id="pageborders">
<div id="page">
</div>
</div>
</body>
Put the title in its own span.
<span id="dialog_title_span">'+dialog_title+'</span>
$('#dialog_title_span').text("new dialog title");

Symfony HttpClient is asynchronous https://symfony.com/doc/current/components/http_client.html.
For example you can
use Symfony\Component\HttpClient\HttpClient;
$client = HttpClient::create();
$response1 = $client->request('GET', 'https://website1');
$response2 = $client->request('GET', 'https://website1');
$response3 = $client->request('GET', 'https://website1');
//these 3 calls with return immediately
//but the requests will fire to the website1 webserver
$response1->getContent(); //this will block until content is fetched
$response2->getContent(); //same
$response3->getContent(); //same
Container
is itself a template with two type parameters.
I would recommend that you change the column names for your join
.
df1.select(col("a") as "df1_a", col("f") as "df1_f")
.join(df2.select(col("a") as "df2_a", col("f") as "df2_f"), col("df1_a" === col("df2_a"))
The resulting DataFrame
will have schema
(df1_a, df1_f, df2_a, df2_f)
I am late to this one by a while, but I'm going to blow your mind, ready?
The reason this is happening, is because you are calling bootstrap in, after you are calling jquery-ui in.
Literally, swap the two so that instead of:
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<script src="js/bootstrap.min.js"></script>
it becomes
<script src="js/bootstrap.min.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
:)
Edit - 26/06/2015 - this keeps attracting interest months later so I thought it was worth an edit. I actually really like the noConflict solution offered in the comment underneath this answer and clarified by user Pretty Cool as a separate answer. As some have reported issues with the bootstrap tooltip when the scripts are swapped. I didn't experience that issue however because I downloaded jquery UI without the tooltip as I didn't need it because bootstrap. So this issue never came up for me.
Edit - 22/07/2015 - Don't confuse
jquery-ui
withjquery
! While Bootstrap's JavaScript requires jQuery to be loaded before, it doesn't rely on jQuery-UI. Sojquery-ui.js
can be loaded afterbootstrap.min.js
, whilejquery.js
always needs to be loaded before Bootstrap.
It means there is a problem with the build path in your project. If it is an android project then it mostly means the target value specified in project.properties file cannot be found. This can also be caused because of other kinds of built problems. But it is shown mostly for built problems only. See here for more details. It is about built error decorater seen in eclipse.
An extract from that page:
Build path problems are sometimes easy to miss among other problems in a project. The Package Explorer and Project Explorer views now show a new decorator on Java projects and working sets that contain build path errors:
The concrete errors can be seen in the Problems view, and if you open the view menu and select Group By > Java Problem Type, they all show up in the Build Path category:
XMLBeans works great if you have a schema for your XML. It creates Java objects for the schema and creates easy to use parse methods.
the way i found was to find the project compiler output (project structure > project). then find the complied folder of the module you wish to turn to a jar, compress it with zip and change the extension of the output from zip to jar.
You need to use cp -t /home/shantanu/tosend
in order to tell it that the argument is the target directory and not a source. You can then change it to -exec ... +
in order to get cp
to copy as many files as possible at once.
Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler
, which defines a method that is invoked when a proxy method is invoked.
You create them by using the call
Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
The arguments are:
classLoader
. Once the class is generated, it is loaded with this class loader.interfaces
. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.invocationHandler
. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler
. When a method from any of the supported interfaces, or hashCode
, equals
, or toString
, is invoked, the method invoke
is invoked on the handler, passing the Method
object for the method to be invoked and the arguments passed.For more on this, see the documentation for the Proxy
class.
Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.
Actually, on 32-bit computers a word is 32-bit, but the DWORD type is a leftover from the good old days of 16-bit.
In order to make it easier to port programs to the newer system, Microsoft has decided all the old types will not change size.

All the platform-dependent types that changed with the transition from 32-bit to 64-bit end with _PTR (DWORD_PTR will be 32-bit on 32-bit Windows and 64-bit on 64-bit Windows).
You can use the Django-Truncate library to delete all data of a table without destroying the table structure.
Example:
pip install django-truncate
settings.py
file:INSTALLED_APPS = [
...
'django_truncate',
]
python manage.py truncate --apps app_name --models table_name
I have a similar issue, and this is what I'm doing:
insert into Preguntas (`EncuestaID`, `Tipo` , `Seccion` , `RespuestaID` , `Texto` ) select '23', `Tipo`, `Seccion`, `RespuestaID`, `Texto` from Preguntas where `EncuestaID`= 18
Been Preguntas:
CREATE TABLE IF NOT EXISTS `Preguntas` (
`ID` int(11) unsigned NOT NULL AUTO_INCREMENT,
`EncuestaID` int(11) DEFAULT NULL,
`Tipo` char(5) COLLATE utf8_unicode_ci DEFAULT NULL,
`Seccion` int(11) DEFAULT NULL,
`RespuestaID` bigint(11) DEFAULT NULL,
`Texto` text COLLATE utf8_unicode_ci ,
PRIMARY KEY (`ID`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=522 ;
So, the ID
is automatically incremented and also I'm using a fixed value ('23') for EncuestaID
.
var str = "helloword~this~is~me";
var exploded = str.splice(~);
the exploded variable will return array and you can access elements of the array be accessing it true exploded[nth] where nth is the index of the value you want to get
In addition to answer of @jww, I would like to say that the configuration in openssl-ca.cnf,
default_days = 1000 # How long to certify for
defines the default number of days the certificate signed by this root-ca will be valid. To set the validity of root-ca itself you should use '-days n' option in:
openssl req -x509 -days 3000 -config openssl-ca.cnf -newkey rsa:4096 -sha256 -nodes -out cacert.pem -outform PEM
Failing to do so, your root-ca will be valid for only the default one month and any certificate signed by this root CA will also have validity of one month.
Just use : echo $array[count($array) - 1];
I Think This will be helpful

This is usually caused by having the .xcodeproj file open instead of .xcworkspace.
When you run 'pod install' for the first time, it will create an .xcworkspace file, which includes your original .xcodeproj and a Pods project. You'll need to close your .xcodeproj and open the .xcworkspace instead.
This is a common issue when creating a project through Xcode's new project wizard - I often forget that I'm not in a workspace, which is required to get Cocoapods to link correctly.
Take a look into NSColorWell class reference.
For SQL Server it should be something like
ALTER TABLE one

The explicit
-keyword can be used to enforce a constructor to be called explicitly.
class C{
public:
explicit C(void) = default;
};
int main(void){
C c();
return 0;
}
the explicit
-keyword in front of the constructor C(void)
tells the compiler that only explicit call to this constructor is allowed.
The explicit
-keyword can also be used in user-defined type cast operators:
class C{
public:
explicit inline operator bool(void) const{
return true;
}
};
int main(void){
C c;
bool b = static_cast<bool>(c);
return 0;
}
Here, explicit
-keyword enforces only explicit casts to be valid, so bool b = c;
would be an invalid cast in this case. In situations like these explicit
-keyword can help programmer to avoid implicit, unintended casts. This usage has been standardized in C++11.
Another post suggests the HTML agility pack:
This is an agile HTML parser that builds a read/write DOM and supports plain XPATH or XSLT (you actually don't HAVE to understand XPATH nor XSLT to use it, don't worry...). It is a .NET code library that allows you to parse "out of the web" HTML files. The parser is very tolerant with "real world" malformed HTML. The object model is very similar to what proposes System.Xml, but for HTML documents (or streams).
'continue' is allowed within an 'except' or 'finally' only if the try block is in a loop. 'continue' will cause the next iteration of the loop to start.
So you can try put your two or more functions in a list and use loop to call your function.
Like this:
funcs = [f,g]
for func in funcs:
try: func()
except: continue
Some "front ends", with the "Use Booleans" option enabled, will treat all TINYINT(1) columns as Boolean, and vice versa.
This allows you to, in the application, use TRUE and FALSE rather than 1 and 0.
This doesn't affect the database at all, since it's implemented in the application.
There is not really a BOOLEAN
type in MySQL. BOOLEAN is just a synonym for TINYINT(1), and TRUE and FALSE are synonyms for 1 and 0.
If the conversion is done in the compiler, there will be no difference in performance in the application. Otherwise, the difference still won't be noticeable.
You should use whichever method allows you to code more efficiently, though not using the feature may reduce dependency on that particular "front end" vendor.
So because pod update SomePod
touches everything in the latest versions of cocoapods, I found a workaround.
Follow the next steps:
Remove SomePod
from the Podfile
Run pod install
pods will now remove SomePod
from our project and from the Podfile.lock
file.
Put back SomePod
into the Podfile
Run pod install
again
This time the latest version of our pod will be installed and saved in the Podfile.lock
.
git hist
- Show the history of current branch
git hist --all
- Show the graph of all branches (including remotes)
git hist master devel
- Show the relationship between two or more branches
git hist --branches
- Show all local branches

I tried placing a label with transparent background over a progress bar but never got it to work properly. So I found Barry's solution here very useful, although I missed the beautiful Vista style progress bar. So I merged Barry's solution with http://www.dreamincode.net/forums/topic/243621-percent-into-progress-bar/ and managed to keep the native progress bar, while displaying text percentage or custom text over it. I don't see any flickering in this solution either. Sorry to dig up and old thread but I needed this today and so others may need it too.
public enum ProgressBarDisplayText
{
Percentage,
CustomText
}
class ProgressBarWithCaption : ProgressBar
{
//Property to set to decide whether to print a % or Text
private ProgressBarDisplayText m_DisplayStyle;
public ProgressBarDisplayText DisplayStyle {
get { return m_DisplayStyle; }
set { m_DisplayStyle = value; }
}
//Property to hold the custom text
private string m_CustomText;
public string CustomText {
get { return m_CustomText; }
set {
m_CustomText = value;
this.Invalidate();
}
}
private const int WM_PAINT = 0x000F;
protected override void WndProc(ref Message m)
{
base.WndProc(m);
switch (m.Msg) {
case WM_PAINT:
int m_Percent = Convert.ToInt32((Convert.ToDouble(Value) / Convert.ToDouble(Maximum)) * 100);
dynamic flags = TextFormatFlags.VerticalCenter | TextFormatFlags.HorizontalCenter | TextFormatFlags.SingleLine | TextFormatFlags.WordEllipsis;
using (Graphics g = Graphics.FromHwnd(Handle)) {
using (Brush textBrush = new SolidBrush(ForeColor)) {
switch (DisplayStyle) {
case ProgressBarDisplayText.CustomText:
TextRenderer.DrawText(g, CustomText, new Font("Arial", Convert.ToSingle(8.25), FontStyle.Regular), new Rectangle(0, 0, this.Width, this.Height), Color.Black, flags);
break;
case ProgressBarDisplayText.Percentage:
TextRenderer.DrawText(g, string.Format("{0}%", m_Percent), new Font("Arial", Convert.ToSingle(8.25), FontStyle.Regular), new Rectangle(0, 0, this.Width, this.Height), Color.Black, flags);
break;
}
}
}
break;
}
}
}
This is the solution for Node.js which is asynchronous.

Edit 2018-05-28 I have changed the example to use Java 8's Time API:
LocalDate d1 = LocalDate.parse("2018-05-26", DateTimeFormatter.ISO_LOCAL_DATE);
LocalDate d2 = LocalDate.parse("2018-05-28", DateTimeFormatter.ISO_LOCAL_DATE);
Duration diff = Duration.between(d1.atStartOfDay(), d2.atStartOfDay());
long diffDays = diff.toDays();
For Rails 4+, use change_column_default
def change
change_column_default :table, :column, value
end
it clears the all the bits that are not in the first byte
Since you are handling 24-hour based time and you have a comma separating the seconds fraction, I recommend that you specify a custom format:
DateTime myDate = DateTime.ParseExact("2009-05-08 14:40:52,531", "yyyy-MM-dd HH:mm:ss,fff",
System.Globalization.CultureInfo.InvariantCulture);
Use the ToDictionary
method directly.
var result =
// as Jon Skeet pointed out, OrderBy is useless here, I just leave it
// show how to use OrderBy in a LINQ query
myClassCollection.OrderBy(mc => mc.SomePropToSortOn)
.ToDictionary(mc => mc.KeyProp.ToString(),
mc => mc.ValueProp.ToString(),
StringComparer.OrdinalIgnoreCase);
In general this is to put an exe/dll on the path. As long as this file wont appear anywhere else:
@echo off
where /q <put filename here>
if %errorlevel% == 1 (
setx PATH "%PATH%;<additional path stuff>"
) else (
echo "already set path"
)
here is a solution:
Bitmap bitmap = BitmapFactory.decodeFile(filePath);
A void*
pointer is used when you want to indicate a pointer to a hunk of memory without specifying the type. C's malloc
returns such a pointer, expecting you to cast it to a particular type immediately. It really isn't useful until you cast it to another pointer type. You're expected to know which type to cast it to, the compiler has no reflection capability to know what the underlying type should be.
You are trying to write to system folders. With ADB you have root (admin) access so you see the system folders of which sdcard is one of them so to send a picture you could use
D:\Program Files\Android\sdk\platform-tools\adb push am files\android sdk\adb.exe push C:\Downloads\anand.jpg /sdcard/pictures/
NB: C:\Downloads\anand.jpg replace with path and name to picture..
I do the following all the time:
$ du -sh backup-lr-May-02-2017-1493723588.tar.gz

-h, --human-readable
print sizes in human readable format (e.g., 1K 234M 2G)

For some Distributions, Cauchy I think, I have found that trapz will overestimate the area, and so the pdf will change depending on the number of bins you select. In which case I do
[N,h]=hist(q_f./theta,30000); % there Is a large range but most of the bins will be empty
plot(h,N/(sum(N)*mean(diff(h))),'+r')
If you go to the folder in finder, right click and select "Get Info" you can go to the "Sharing and Permissions" section for the folder and allow "Read & Write" to "everyone"
This is what I do to make symlinks pass with this error. Also brew seems to reset the permissions on the folder also as if you hadn't altered anything
