Microsoft IE does not support a name as second argument.
window.open('url', 'window name', 'window settings');
Problem is window name
. This will work:
window.open('url', '', 'window settings')
Microsoft only allows the following arguments, If using that argument at all:
import urllib2
Traceback (most recent call last):
File "", line 1, in
import urllib2
ImportError: No module named 'urllib2' So urllib2 has been been replaced by the package : urllib.request.
Here is the PEP link (Python Enhancement Proposals )
http://www.python.org/dev/peps/pep-3108/#urllib-package
so instead of urllib2 you can now import urllib.request and then use it like this:
>>>import urllib.request
>>>urllib.request.urlopen('http://www.placementyogi.com')

I don't understand why the files were relocated to /platform-tools from /tools. It seems ALL development tools I have tried, appcelerator for one, have their setup software look for these files in /tools and fail setup. The "work around" involves a few different bits of trickery wherein you either...1) set up a soft link to tell the operating system "if you look for file "x" here it is really over here. or 2) simpler method ... make a copy of all the /platform-tools default (pre-additional android sdk installations) files and place them into the /tools folder. this circumvents the relocation that the newer sdk have done. Then of course YOU MUST SET PATH ENVIRONMENT VARIABLES TO POINT TO THE SDK LOCATION (sometimes to the Android-sdk-[operating system name:Android-sdk-windows or Android-sdk-mac_x86 ect. ] and to the /platform-tools and sometimes to /tools. it is a trial and error pain. But when it finally is working ...it works.

Remainder is simply the remaining part after the arithmetic division between two integer number whereas Modulus is the sum of remainder and divisor when they are oppositely signed and remaining part after the arithmetic division when remainder and divisor both are of same sign.
Example of Remainder:
10 % 3 = 1 [here divisible is 10 which is positively signed so the result will also be positively signed]
-10 % 3 = -1 [here divisible is -10 which is negatively signed so the result will also be negatively signed]
10 % -3 = 1 [here divisible is 10 which is positively signed so the result will also be positively signed]
-10 % -3 = -1 [here divisible is -10 which is negatively signed so the result will also be negatively signed]
Example of Modulus:
5 % 3 = 2 [here divisible is 5 which is positively signed so the remainder will also be positively signed and the divisor is also positively signed. As both remainder and divisor are of same sign the result will be same as remainder]
-5 % 3 = 1 [here divisible is -5 which is negatively signed so the remainder will also be negatively signed and the divisor is positively signed. As both remainder and divisor are of opposite sign the result will be sum of remainder and divisor -2 + 3 = 1]
5 % -3 = -1 [here divisible is 5 which is positively signed so the remainder will also be positively signed and the divisor is negatively signed. As both remainder and divisor are of opposite sign the result will be sum of remainder and divisor 2 + -3 = -1]
-5 % -3 = -2 [here divisible is -5 which is negatively signed so the remainder will also be negatively signed and the divisor is also negatively signed. As both remainder and divisor are of same sign the result will be same as remainder]
I hope this will clearly distinguish between remainder and modulus.
You can't do replacing, you have to replace SOMETHING with SOMETHING, and you neither have both.
In .Net 1.1 and earlier, Application.Exit was not a wise choice and the MSDN docs specifically recommended against it because all message processing stopped immediately.
In later versions however, calling Application.Exit will result in Form.Close being called on all open forms in the application, thus giving you a chance to clean up after yourself, or even cancel the operation all together.
As of EF 5.0, you need to include the System.ComponentModel.DataAnnotations.Schema
namespace.
It is indeed a foreign key error, you can find out using perror:
shell$ perror 150
MySQL error code 150: Foreign key constraint is incorrectly formed
To find out more details about what failed, you can use SHOW ENGINE INNODB STATUS
and look for the LATEST FOREIGN KEY ERROR section it contains details about what is wrong.
In your case, it is most likely cause something is referencing the country_id column.
Add the key View controller-based status bar appearance

The two types are distinct in JavaScript as well as TypeScript - TypeScript just gives us syntax to annotate and check types as we go along.
String
refers to an object instance that has String.prototype
in its prototype chain. You can get such an instance in various ways e.g. new String('foo')
and Object('foo')
. You can test for an instance of the String
type with the instanceof
operator, e.g. myString instanceof String
.
string
is one of JavaScript's primitive types, and string
values are primarily created with literals e.g. 'foo'
and "bar"
, and as the result type of various functions and operators. You can test for string
type using typeof myString === 'string'
.
The vast majority of the time, string
is the type you should be using - almost all API interfaces that take or return strings will use it. All JS primitive types will be wrapped (boxed) with their corresponding object types when using them as objects, e.g. accessing properties or calling methods. Since String
is currently declared as an interface rather than a class in TypeScript's core library, structural typing means that string
is considered a subtype of String
which is why your first line passes compilation type checks.
To make multiple checking statements more readable (and avoid nested ifs):
var tmp = 'Test[[email protected]]';
var posStartEmail = undefined;
var posEndEmail = undefined;
var email = undefined;
do {
if (tmp.toLowerCase().substring(0,4) !== 'test') { break; }
posStartEmail = tmp.toLowerCase().substring(4).indexOf('[');
posEndEmail = tmp.toLowerCase().substring(4).indexOf(']');
if (posStartEmail === -1 || posEndEmail === -1) { break; }
email = tmp.substring(posStartEmail+1+4,posEndEmail);
if (email.indexOf('@') === -1) { break; }
// all checks are done - do what you intend to do
alert ('All checks are ok')
break; // the most important break of them all
} while(true);
Here's a version that's much simpler - not sure how performant it is. Heavily based on some django snippet I found while building RGBA -> JPG + BG
support for sorl thumbnails.
from PIL import Image
png = Image.open(object.logo.path)
png.load() # required for png.split()
background = Image.new("RGB", png.size, (255, 255, 255))
background.paste(png, mask=png.split()[3]) # 3 is the alpha channel
background.save('foo.jpg', 'JPEG', quality=80)
Result @80%
Result @ 50%
It's really incredible ... All are proposing some special package for playing an animated GIF, at the moment that it can be done with Tkinter and the classic PIL module!
Here is my own GIF animation method (I created a while ago). Very simple:
from Tkinter import *
from PIL import Image, ImageTk
from time import sleep
def stop(event):
global play
play = False
exit()
root = Tk()
root.bind("<Key>", stop) # Press any key to stop
GIFfile = {path_to_your_GIF_file}
im = Image.open(GIFfile); img = ImageTk.PhotoImage(im)
delay = float(im.info['duration'])/1000; # Delay used in the GIF file
lbl = Label(image=img); lbl.pack() # Create a label where to display images
play = True; frame = 0
while play:
sleep(delay);
frame += 1
try:
im.seek(frame); img = ImageTk.PhotoImage(im)
lbl.config(image=img); root.update() # Show the new frame/image
except EOFError:
frame = 0 # Restart
root.mainloop()
You can set your own means to stop the animation. Let me know if you like to get the full version with play/pause/quit buttons.
Note: I am not sure if the consecutive frames are read from memory or from the file (disk). In the second case it would be more efficient if they all read at once and saved into an array (list). (I'm not so interested to find out! :)
If you're running Charles and trying to build a docker container then you'll most likely get this error.
Make sure to disable Charles (macos) proxy under proxy -> macOS proxy
Charles is an
HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet.
So anything similar may cause the same issue.
These days with jQuery 1.6.1 or above it is recommended that .prop() be used when setting boolean attributes/properties.
$("#fieldName").prop("readonly", true);
The compiler is using the UTF-8 character encoding to read your source file. But the file must have been written by an editor using a different encoding. Open your file in an editor set to the UTF-8 encoding, fix the quote mark, and save it again.
Alternatively, you can find the Unicode point for the character and use a Unicode escape in the source code. For example, the character A
can be replaced with the Unicode escape \u0041
.
By the way, you don't need to use the begin- and end-line anchors ^
and $
when using the matches()
method. The entire sequence must be matched by the regular expression when using the matches()
method. The anchors are only useful with the find()
method.

You can always run this:
java -cp HelloWorld.jar HelloWorld
-cp HelloWorld.jar
adds the jar to the classpath, then HelloWorld
runs the class you wrote.
To create a runnable jar with a main class with no package, add Class-Path: .
to the manifest:
Manifest-Version: 1.0
Class-Path: .
Main-Class: HelloWorld
I would advise using a package
to give your class its own namespace. E.g.
package com.stackoverflow.user.blrp;
public class HelloWorld {
...
}
<select name="foo" id="foo">
<option value="1">a</option>
<option value="2">b</option>
<option value="3">c</option>
</select>
<input type="button" id="button" value="Button" />
});
<script> ("#foo").val() </script>
which returns 1 if you have selected a and so on..

Java is crossplatform, and nanoTime is platform-dependent. If you use Java - when don't use nanoTime. I found real bugs across different jvm implementations with this function.
You can always do something like this:
update mytable t
set SomeColumn = c.ComputedValue
from (select *, 42 as ComputedValue from mytable where id = 1) c
where t.id = c.id
You can now also use with statement inside update
update mytable t
set SomeColumn = c.ComputedValue
from (with abc as (select *, 43 as ComputedValue_new from mytable where id = 1
select *, 42 as ComputedValue, abc.ComputedValue_new from mytable n1
inner join abc on n1.id=abc.id) c
where t.id = c.id

If you prefer splitting a CSV list in SQL, there's a different way to do it using Common Table Expressions (CTEs). See Efficient way to string split using CTE.
Matlab is good at doing number crunching. Also Matrix and matrix manipulation. It has many helpful built in libraries(depends on the what version) I think it is easier to use than python if you are going to be calculating equations.

jobs -p does not work in all shells if called in a sub-shell, possibly unless its output is redirected into a file but not a pipe. (I assume it was originally intended for interactive use only.)
What about the following:
trap 'while kill %% 2>/dev/null; do jobs > /dev/null; done' INT TERM EXIT [...]
The call to "jobs" is needed with Debian's dash shell, which fails to update the current job ("%%") if it is missing.
In Ubuntu 16.04.3 LTS, the next command works for me:
exit
Then I've login again.
If this doesn't work why not simply do a foreach loop over the dictionary adding all the items to the combobox?
foreach(var item in userCache)
{
userListComboBox.Items.Add(new ListItem(item.Key, item.Value));
}
In R2013b or later you can use a table:
>> table = readtable('myfile.txt','Delimiter',';','ReadVariableNames',false)
>> table =
Var1 Var2 Var3 Var4 Var5 Var6 Var7 Var8 Var9 Var10
____ _____ _____ _____ _____ __________ __________ ________ ____ _____
4 'abc' 'def' 'ghj' 'klm' '' '' '' NaN NaN
NaN '' '' '' '' 'Test' 'text' '0xFF' NaN NaN

As others have already shared, app.set('config', config)
is great for this. I just wanted to add something that I didn't see in existing answers that is quite important. A Node.js instance is shared across all requests, so while it may be very practical to share some config
or router
object globally, storing runtime data globally will be available across requests and users. Consider this very simple example:
var express = require('express');
var app = express();
app.get('/foo', function(req, res) {
app.set('message', "Welcome to foo!");
res.send(app.get('message'));
});
app.get('/bar', function(req, res) {
app.set('message', "Welcome to bar!");
// some long running async function
var foo = function() {
res.send(app.get('message'));
};
setTimeout(foo, 1000);
});
app.listen(3000);
If you visit /bar
and another request hits /foo
, your message will be "Welcome to foo!". This is a silly example, but it gets the point across.
There are some interesting points about this at Why do different node.js sessions share variables?.
Much Easier approach.
Just include dependency in your app level gradle file
compile 'com.journeyapps:zxing-android-embedded:3.0.1@aar'
compile 'com.google.zxing:core:3.2.0'
Define one button in your xml file and and write below code in Java file in OnCreate()and inside the OnClick listener of button
new IntentIntegrator(this).initiateScan();
And write below code after OnCreate() of the Java file
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if(result != null) {
if(result.getContents() == null) {
Log.d("MainActivity", "Cancelled scan");
Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
} else {
Log.d("MainActivity", "Scanned");
String st_scanned_result = result.getContents();
Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
}
}
}
You can do it by setting the aspect of the image manually (or by letting it auto-scale to fill up the extent of the figure).
By default, imshow
sets the aspect of the plot to 1, as this is often what people want for image data.
In your case, you can do something like:
import matplotlib.pyplot as plt
import numpy as np
grid = np.random.random((10,10))
fig, (ax1, ax2, ax3) = plt.subplots(nrows=3, figsize=(6,10))
ax1.imshow(grid, extent=[0,100,0,1])
ax1.set_title('Default')
ax2.imshow(grid, extent=[0,100,0,1], aspect='auto')
ax2.set_title('Auto-scaled Aspect')
ax3.imshow(grid, extent=[0,100,0,1], aspect=100)
ax3.set_title('Manually Set Aspect')
plt.tight_layout()
plt.show()
This problem-related to lPods can be fixed by following the steps below

I think the answer is here (possibly duplicate):
How to test if a file is a directory in a batch script?
IF EXIST %VAR%\NUL ECHO It's a directory
Replace %VAR% with your directory. Please read the original answer because includes details about handling white spaces in the folder name.
As foxidrive said, this might not be reliable on NT class windows. It works for me, but I know it has some limitations (which you can find in the referenced question)
if exist "c:\folder\" echo folder exists
should be enough for modern windows.
This should work. Make sure each button has a unique ID. (Replace Choose_Yes and Choose_No with the IDs of your two radio buttons)
document.getElementById("Choose_Yes").checked = false;
document.getElementById("Choose_No").checked = false;
An example of how the radio buttons should be named:
<input type="radio" name="Choose" id="Choose_Yes" value="1" /> Yes
<input type="radio" name="Choose" id="Choose_No" value="2" /> No
One other major difference that is not yet mentioned here is that CURLOPT_POSTFIELDS
can't handle nested arrays.
If we take the nested array ['a' => 1, 'b' => [2, 3, 4]]
then this should be be parameterized as a=1&b[]=2&b[]=3&b[]=4
(the [
and ]
will be/should be URL encoded). This will be converted back automatically into a nested array on the other end (assuming here the other end is also PHP).
This will work:
var_dump(http_build_query(['a' => 1, 'b' => [2, 3, 4]]));
// output: string(36) "a=1&b%5B0%5D=2&b%5B1%5D=3&b%5B2%5D=4"
This won't work:
curl_setopt($ch, CURLOPT_POSTFIELDS, ['a' => 1, 'b' => [2, 3, 4]]);
This will give you a notice. Code execution will continue and your endpoint will receive parameter b
as string "Array"
:
PHP Notice: Array to string conversion in ... on line ...
If you want to calculate your own location, then first set StartPosition
to FormStartPosition.Manual
:
Form Child = new Form();
Child.StartPosition = FormStartPosition.Manual;
Child.Location = new Point(Location.X + (Width - Child.Width) / 2, Location.Y + (Height - Child.Height) / 2);
Child.Show(this);
Where this is the main/parent form, just like Location.X.
Default value for StartPosition
is FormStartPosition.CenterParent
and therefore it changes the child's location after showing.
Compiling PIL on Windows x64 is apparently a bit of a pain. (Well, compiling anything on Windows is a bit of a pain in my experience. But still.) As well as PIL itself you'll need to build many dependencies. See these notes from the mailing list too.
There's an unofficial precompiled binary for x64 linked from this message, but I haven't tried it myself. Might be worth a go if you don't mind the download being from one of those slightly dodgy file-upload sites. Other than that... well, you could always give up and instead the 32-bit Python binary instead.
It's not a direct answer on question (its not about Actions
), but it also allow you to scroll easily to required element:
element = driver.find_element_by_id('some_id')
element.location_once_scrolled_into_view
This actually intend to return you coordinates (x
, y
) of element on page, but also scroll down right to target element
While the project was in debug mode, the solution was not. When I changed it, it worked.

If you take a look at the sources for django.contrib.auth.views.password_reset you'll see that it uses RequestContext
. The upshot is, you can use Context Processors to modify the context which may allow you to inject the information that you need.
The b-list has a good introduction to context processors.
Edit (I seem to have been confused about what the actual question was):
You'll notice that password_reset
takes a named parameter called template_name
:
def password_reset(request, is_admin_site=False,
template_name='registration/password_reset_form.html',
email_template_name='registration/password_reset_email.html',
password_reset_form=PasswordResetForm,
token_generator=default_token_generator,
post_reset_redirect=None):
Check password_reset for more information.
... thus, with a urls.py like:
from django.conf.urls.defaults import *
from django.contrib.auth.views import password_reset
urlpatterns = patterns('',
(r'^/accounts/password/reset/$', password_reset, {'template_name': 'my_templates/password_reset.html'}),
...
)
django.contrib.auth.views.password_reset
will be called for URLs matching '/accounts/password/reset'
with the keyword argument template_name = 'my_templates/password_reset.html'
.
Otherwise, you don't need to provide any context as the password_reset
view takes care of itself. If you want to see what context you have available, you can trigger a TemplateSyntax
error and look through the stack trace find the frame with a local variable named context
. If you want to modify the context then what I said above about context processors is probably the way to go.
In summary: what do you need to do to use your own template? Provide a template_name
keyword argument to the view when it is called. You can supply keyword arguments to views by including a dictionary as the third member of a URL pattern tuple.
I think another place to look is /var/lib
.
If you go there you can see three mysql folders with 'interesting' permissions:
user group
mysql mysql
Here is what I did to solve my problem with root password:
after running
sudo apt-get purge mysql*
sudo rm -rf /etc/mysql
I also ran the following (instead of my_username put yours):
cd /var/lib
sudo chown --from=mysql <my_username> mysql* -R
sudo rm -rf mysql*
And then:
sudo apt-get install mysql-server
which prompted me to select a new root password. I hope it helps
h = { "true"=>true, true=>true, "false"=>false, false=>false }
["true", true, "false", false].map { |e| h[e] }
#=> [true, true, false, false]
But to make sure that your new row is accessible in the new table, you need to close the table:
DataTable destination = new DataTable(source.TableName);
destination = source.Clone();
DataRow sourceRow = source.Rows[0];
destination.ImportRow(sourceRow);

Do as this:
Windows -> Show View -> Servers
Then in the Servers view, right-click and add new. It will show a pop up containing many server vendors. Under Apache select Tomcat v7.0 (Depending upon your downloaded server version). And in the run time configuration point it to the Tomcat folder you have downloaded.
You can try this article. It has the info you want !!

Array slicing like in Python (From the rebash library):
array_slice() {
local __doc__='
Returns a slice of an array (similar to Python).
From the Python documentation:
One way to remember how slices work is to think of the indices as pointing
between elements, with the left edge of the first character numbered 0.
Then the right edge of the last element of an array of length n has
index n, for example:
```
+---+---+---+---+---+---+
| 0 | 1 | 2 | 3 | 4 | 5 |
+---+---+---+---+---+---+
0 1 2 3 4 5 6
-6 -5 -4 -3 -2 -1
```
>>> local a=(0 1 2 3 4 5)
>>> echo $(array.slice 1:-2 "${a[@]}")
1 2 3
>>> local a=(0 1 2 3 4 5)
>>> echo $(array.slice 0:1 "${a[@]}")
0
>>> local a=(0 1 2 3 4 5)
>>> [ -z "$(array.slice 1:1 "${a[@]}")" ] && echo empty
empty
>>> local a=(0 1 2 3 4 5)
>>> [ -z "$(array.slice 2:1 "${a[@]}")" ] && echo empty
empty
>>> local a=(0 1 2 3 4 5)
>>> [ -z "$(array.slice -2:-3 "${a[@]}")" ] && echo empty
empty
>>> [ -z "$(array.slice -2:-2 "${a[@]}")" ] && echo empty
empty
Slice indices have useful defaults; an omitted first index defaults to
zero, an omitted second index defaults to the size of the string being
sliced.
>>> local a=(0 1 2 3 4 5)

If you're just checking before trying to add a new value, use the ContainsKey
method:
if (!openWith.ContainsKey("ht"))
{
openWith.Add("ht", "hypertrm.exe");
}
If you're checking that the value exists, use the TryGetValue
method as described in Jon Skeet's answer.
Since Beautiful Soup 4.4.0.
a parameter called string
does the work that text
used to do in the previous versions.
string
is for finding strings, you can combine it with arguments that find tags: Beautiful Soup will find all tags whose .string matches your value for the string. This code finds the tags whose .string is “Elsie”:
soup.find_all("td", string="Elsie")
For more information about string have a look this section https://www.crummy.com/software/BeautifulSoup/bs4/doc/#the-string-argument
Try this:
SELECT a.person, a.group, a.age FROM person AS a WHERE
(SELECT COUNT(*) FROM person AS b
WHERE b.group = a.group AND b.age >= a.age) <= 2
ORDER BY a.group ASC, a.age DESC
div.test td, div.test caption, div.test th
works for me.

UPDATE This feature is removed since Firefox 17 (see https://bugzilla.mozilla.org/show_bug.cgi?id=546848).
On Firefox you (the programmer) can do this from within a JavaScript file:
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserWrite");
and you (the browser user) will be prompted to allow access. (for Firefox you just need to do this once every time the browser is started)
If the browser user is someone else, they have to grant permission.
Define "much faster". Asymptotically they're about the same. The differences lie in how they make use of secondary storage. The Wikipedia articles on B-trees and B+trees look pretty trustworthy.
I found a good tutorial on oreilly.com.
Example code:
<canvas id="canvas" width ='600px'></canvas><br />
Enter your Text here .The Text will get drawn on the canvas<br />
<input type="text" id="text" onKeydown="func();"></input><br />
</body><br />

function func(){
var e=document.getElementById("text"),t=document.getElementById("canvas"),n=t.getContext("2d");
n.fillStyle="#990000";n.font="30px futura";n.textBaseline="top";n.fillText(e.value,150,0);n.fillText("thank you, ",200,100);

just add in your backend API new property's into response body. from example .net core:
[Authorize]
[HttpGet]
public async Task<IActionResult> GetUsers([FromQuery]UserParams userParams)
{
var users = await _repo.GetUsers(userParams);
var usersToReturn = _mapper.Map<IEnumerable<UserForListDto>>(users);
// create new object and add into it total count param etc
var UsersListResult = new
{
usersToReturn,
currentPage = users.CurrentPage,
pageSize = users.PageSize,
totalCount = users.TotalCount,
totalPages = users.TotalPages
};
return Ok(UsersListResult);
}
In body response it look like this
{
"usersToReturn": [
{
"userId": 1,
"username": "[email protected]",
"firstName": "Joann",
"lastName": "Wilson",
"city": "Armstrong",
"phoneNumber": "+1 (893) 515-2172"
},
{
"userId": 2,
"username": "[email protected]",
"firstName": "Booth",
"lastName": "Drake",
"city": "Franks",
"phoneNumber": "+1 (800) 493-2168"
}
],
// metadata to pars in client side
"currentPage": 1,
"pageSize": 2,
"totalCount": 87,
"totalPages": 44
}
The following is from Adobe docs.
The media queries specification also provides the keyword only
, which is intended to hide media queries from older browsers. Like not
, the keyword must come at the beginning of the declaration. For example:
media="only screen and (min-width: 401px) and (max-width: 600px)"
Browsers that don't recognize media queries expect a comma-separated list of media types, and the specification says they should truncate each value immediately before the first nonalphanumeric character that isn't a hyphen. So, an old browser should interpret the preceding example as this:
media="only"
Because there is no such media type as only, the stylesheet is ignored. Similarly, an old browser should interpret
media="screen and (min-width: 401px) and (max-width: 600px)"
as
media="screen"
In other words, it should apply the style rules to all screen devices, even though it doesn't know what the media queries mean.
Unfortunately, IE 6–8 failed to implement the specification correctly.
Instead of applying the styles to all screen devices, it ignores the style sheet altogether.
In spite of this behavior, it's still recommended to prefix media queries with only if you want to hide the styles from other, less common browsers.
So, using
media="only screen and (min-width: 401px)"
and
media="screen and (min-width: 401px)"
will have the same effect in IE6-8: both will prevent those styles from being used. They will, however, still be downloaded.
Also, in browsers that support CSS3 media queries, both versions will load the styles if the viewport width is larger than 401px
and the media type is screen.
I'm not entirely sure which browsers that don't support CSS3 media queries would need the only
version
media="only screen and (min-width: 401px)"
as opposed to
media="screen and (min-width: 401px)"
to make sure it is not interpreted as
media="screen"
It would be a good test for someone with access to a device lab.

Suggest the following simplification: capture return value from Workbooks.Add
instead of subscripting Windows()
afterward, as follows:
Set wkb = Workbooks.Add
wkb.SaveAs ...
wkb.Activate ' instead of Windows(expression).Activate
General Philosophy Advice:
Avoid use Excel's built-ins: ActiveWorkbook, ActiveSheet, and Selection: capture return values, and, favor qualified expressions instead.
Use the built-ins only once and only in outermost macros(subs) and capture at macro start, e.g.
Set wkb = ActiveWorkbook
Set wks = ActiveSheet
Set sel = Selection
During and within macros do not rely on these built-in names, instead capture return values, e.g.
Set wkb = Workbooks.Add 'instead of Workbooks.Add without return value capture
wkb.Activate 'instead of Activeworkbook.Activate
Also, try to use qualified expressions, e.g.
wkb.Sheets("Sheet3").Name = "foo" ' instead of Sheets("Sheet3").Name = "foo"
or
Set newWks = wkb.Sheets.Add
newWks.Name = "bar" 'instead of ActiveSheet.Name = "bar"
Use qualified expressions, e.g.
newWks.Name = "bar" 'instead of `xyz.Select` followed by Selection.Name = "bar"
These methods will work better in general, give less confusing results, will be more robust when refactoring (e.g. moving lines of code around within and between methods) and, will work better across versions of Excel. Selection, for example, changes differently during macro execution from one version of Excel to another.
Also please note that you'll likely find that you don't need to .Activate
nearly as much when using more qualified expressions. (This can mean the for the user the screen will flicker less.) Thus the whole line Windows(expression).Activate
could simply be eliminated instead of even being replaced by wkb.Activate
.
(Also note: I think the .Select statements you show are not contributing and can be omitted.)
(I think that Excel's macro recorder is responsible for promoting this more fragile style of programming using ActiveSheet, ActiveWorkbook, Selection, and Select so much; this style leaves a lot of room for improvement.)
And remember to use parenthesis!
Keep in mind that &
operator takes a precedence over operators such as >
or <
etc. That is why
4 < 5 & 6 > 4
evaluates to False
. Therefore if you're using pd.loc
, you need to put brackets around your logical statements, otherwise you get an error. That's why do:
df.loc[(df['A'] > 10) & (df['B'] < 15)]
instead of
df.loc[df['A'] > 10 & df['B'] < 15]
which would result in
TypeError: cannot compare a dtyped [float64] array with a scalar of type [bool]
This was how I solved it:
mysql> DROP DATABASE mydatabase;
ERROR 1010 (HY000): Error dropping database (can't rmdir '.\mydatabase', errno: 13)
mysql>
I went to delete this directory: C:\...\UniServerZ\core\mysql\data\mydatabase
.
mysql> DROP DATABASE mydatabase;
ERROR 1008 (HY000): Can't drop database 'mydatabase'; database doesn't exist
In June 2014 RFC7231 obsoletes RFC2616. If you are doing REST over HTTP then RFC7231 describes exactly what behaviour is expected from GET, PUT, POST and DELETE
You can setup an interval to keep checking if the user has scrolled then do something accordingly.
Borrowing from the great John Resig in his article.
Example:
let didScroll = false;
window.onscroll = () => didScroll = true;
setInterval(() => {
if ( didScroll ) {
didScroll = false;
console.log('Someone scrolled me!')
}
}, 250);
To check for an exact match you would use num == line
. But line
has an end-of-line character \n
or \r\n
which will not be in num
since raw_input
strips the trailing newline. So it may be convenient to remove all whitespace at the end of line
with
line = line.rstrip()
with open("file.txt") as search:
for line in search:
line = line.rstrip() # remove '\n' at end of line
if num == line:
print(line )
Complete code:

{
UIButton *button = [[UIButton alloc] initWithFrame:frame];
button.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
[button setTitle:title forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
UIImage *newImage = [image stretchableImageWithLeftCapWidth:12.0 topCapHeight:0.0];
[button setBackgroundImage:newImage forState:UIControlStateNormal];
UIImage *newPressedImage = [imagePressed stretchableImageWithLeftCapWidth:12.0 topCapHeight:0.0];
[button setBackgroundImage:newPressedImage forState:UIControlStateHighlighted];
[button addTarget:target action:selector forControlEvents:UIControlEventTouchUpInside];
// in case the parent view draws with a custom color or gradient, use a transparent color
button.backgroundColor = [UIColor clearColor];
return button;
}
UIImage *buttonBackground = UIImage imageNamed:@"whiteButton.png";
UIImage *buttonBackgroundPressed = UIImage imageNamed:@"blueButton.png";
CGRect frame = CGRectMake(0.0, 0.0, kStdButtonWidth, kStdButtonHeight);
UIButton *button = [FinishedStatsView buttonWithTitle:title
target:target
selector:action
frame:frame
image:buttonBackground
imagePressed:buttonBackgroundPressed
darkTextColor:YES];
[self addSubview:button];
To set an image:
UIImage *buttonImage = [UIImage imageNamed:@"Home.png"];
[myButton setBackgroundImage:buttonImage forState:UIControlStateNormal];
[self.view addSubview:myButton];
To remove an image:
[button setBackgroundImage:nil forState:UIControlStateNormal];
You can use addition to concatenate strings.
Strings are added by being joined into a larger string.
jq '.users[] | .first + " " + .last'
The above works when both first
and last
are string. If you are extracting different datatypes(number and string), then we need to convert to equivalent types. Referring to solution on this question. For example.
jq '.users[] | .first + " " + (.number|tostring)'
Although it doesn't apply to this specific example, Option 1 allows you to initialize member variables of reference type (or const
type, as pointed out below). Option 2 doesn't. In general, Option 1 is the more powerful approach.
holder.text.setTextColor(Color.rgb(200,0,0));
or
myTextView.setTextColor(0xAARRGGBB);
JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm
page.
One idea is to let the the browser know that it should redirect by adding a redirect
variable to to the resulting object and checking for it in JQuery:
$(document).ready(function(){
jQuery.ajax({
type: "GET",
url: "populateData.htm",
dataType:"json",
data:"userId=SampleUser",
success:function(response){
if (response.redirect) {
window.location.href = response.redirect;
}
else {
// Process the expected results...
}
},
error: function(xhr, textStatus, errorThrown) {
alert('Error! Status = ' + xhr.status);
}
});
});
You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1")
and in JQuery you do on success(!):
//....
success:function(response){
if (response.getResponseHeader('REQUIRES_AUTH') === '1'){
window.location.href = 'login.htm';
}
else {
// Process the expected results...
}
}
//....
Hope that helps.
My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.
The best option I found and the less intrusive, is to set a tag param in your xml, like
PHONE XML LAYOUT
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:tag="phone"/>
TABLET XML LAYOUT
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:tag="tablet">
...
</RelativeLayout>
and then call this in your activity class:
View viewPager = findViewById(R.id.pager);
Log.d(getClass().getSimpleName(), String.valueOf(viewPager.getTag()));
Hope it works for u.
When people talk about the ".net framework" they tend to be combining two main areas - the runtime library and the virtual machine that actually runs the .net code.
When you create a class library in Visual Studio in C#, the DLL follows a prescribed format - very roughly, there is section that contains meta data that describes what classes are included in it and what functions they have, etc.. and that describes where in the binary those objects exist. This common .net format is what allows libraries to be shared between .net languages (C#, VB.Net, F# and others) easily. Although much of the .net "runtime library" is written in C# now (I believe), you can imagine how many of them could have been written in unmanaged languages but arranged in this prescribed format so that they could be consumed by .net languages.
The real "meat" of the library that you build consists of CIL ("Common Intermediate Language") which is a bit like the assembly language of .net - again, this language is the common output of all .net languages, which is what makes .net libraries consumable by any .net language.
Using the tool "ildasm.exe", which is freely available in Microsoft SDKs (and might already be on your computer), you can see how C# code is converted into meta data and IL. I've included a sample at the bottom of this answer as an example.
When you run execute .net code, what is commonly happening is the .net virtual machine is reading that IL and processing it. This is the other side of .net and, again, you can likely imagine that this could easily be written in an unmanaged language - it "only" needs to read VM instructions and run them (and integrate with the garbage collector, which also need not be .net code).
What I've described is (again, roughly) what happens when you build an executable in Visual Studio (for more information, I highly recommend the book "CLR via C# by Jeffrey Richter" - it's very detailed and excellently written).
However, there are times that you might write C# that will not be executed within a .net environment - for example, Bridge.NET "compiles" C# code into JavaScript which is then run in the browser (the team that produce it have gone to the effort of writing versions of the .net runtime library that are written in JavaScript and so the power and flexibility of the .net library is available to the generated JavaScript). This is a perfect example of the separation between C# and .net - it's possible to write C# for different "targets"; you might target the .net runtime environment (when you build an executable) or you might target the browser environment (when you use Bridge.NET).
A (very) simple example class:
using System;
namespace Example
{
public class Class1
{
public void SayHello()
{
Console.WriteLine("Hello");
}
}
}
The resulting meta data and IL (retrieved via ildasm.exe):

Set the buildToolsVersion '26.0.2'
then change classpath 'com.android.tools.build:gradle:3.0.1'
.
Make sure you set compileSdkVersion
to 26
whiles targetSdkVersion
is also set 26
.
It is also appropriate to sent set compile 'com.android.support:appcompat-v7:26.0.2'
.
To be a little more ECMAScript-5.1-precise than the other answers (some might say pedantic):
In JavaScript, variables (and properties) don't have types: values do. Further, there are only 6 types of values: Undefined, Null, Boolean, String, Number, and Object. (Technically, there are also 7 "specification types", but you can't store values of those types as properties of objects or values of variables--they are only used within the spec itself, to define how the language works. The values you can explicitly manipulate are of only the 6 types I listed.)
The spec uses the notation "Type(x)" when it wants to talk about "the type of x". This is only a notation used within the spec: it is not a feature of the language.
As other answers make clear, in practice you may well want to know more than the type of a value--particularly when the type is Object. Regardless, and for completeness, here is a simple JavaScript implementation of Type(x) as it is used in the spec:
function Type(x) {
if (x === null) {
return 'Null';
}
switch (typeof x) {
case 'undefined': return 'Undefined';
case 'boolean' : return 'Boolean';
case 'number' : return 'Number';
case 'string' : return 'String';
default : return 'Object';
}
}
I had to use a slightly extended version @Erwin Brandstetter used:
DO
$do$
DECLARE
_db TEXT := 'some_db';
_user TEXT := 'postgres_user';
_password TEXT := 'password';
BEGIN
CREATE EXTENSION IF NOT EXISTS dblink; -- enable extension
IF EXISTS (SELECT 1 FROM pg_database WHERE datname = _db) THEN
RAISE NOTICE 'Database already exists';
ELSE
PERFORM dblink_connect('host=localhost user=' || _user || ' password=' || _password || ' dbname=' || current_database());
PERFORM dblink_exec('CREATE DATABASE ' || _db);
END IF;
END
$do$
I had to enable the dblink
extension, plus i had to provide the credentials for dblink.
Works with Postgres 9.4.
This simple formula should work.
Give the element whose text will contain a tab the following CSS property:
white-space:pre
.
Otherwise your html may not render tabs at all. Then, wherever you want to have a tab in your text, type 	
.
Since you didn't mention CSS, if you want to do this without a CSS file, just use
<tag-name style="white-space:pre">text in element	more text</tag-name>
in your HTML.
os._exit()
:
exit(0)
:
exit(1)
:
sys.exit()
:
quit()
:
Basically they all do the same thing, however, it also depends on what you are doing it for.
I don't think you left anything out and I would recommend getting used to quit()
or exit()
.
You would use sys.exit()
and os._exit()
mainly if you are using big files or are using python to control terminal.
Otherwise mainly use exit()
or quit()
.
I tried several ways to do it, including the first ones said by @Joshua Fox. But some don't recognize frequent mimetypes like for PDF files, and other could not be trustable with fake files (I tried with a RAR file with extension changed to TIF). The solution I found, as also is said by @Joshua Fox in a superficial way, is to use MimeUtil2, like this:
MimeUtil2 mimeUtil = new MimeUtil2();
mimeUtil.registerMimeDetector("eu.medsea.mimeutil.detector.MagicMimeMimeDetector");
String mimeType = MimeUtil2.getMostSpecificMimeType(mimeUtil.getMimeTypes(file)).toString();
With node-fs-extra you can do it easily.
npm install --save fs-extra
Then use the outputFile
method. Its documentation says:
Almost the same as writeFile (i.e. it overwrites), except that if the parent directory does not exist, it's created.
You can use it in three ways:
const fse = require('fs-extra');
fse.outputFile('tmp/test.txt', 'Hey there!', err => {
if(err) {
console.log(err);
} else {
console.log('The file was saved!');
}
})
If you use promises, and I hope so, this is the code:
fse.outputFile('tmp/test.txt', 'Hey there!')
.then(() => {
console.log('The file was saved!');
})
.catch(err => {
console.error(err)
});
If you want a sync version, just use this code:
fse.outputFileSync('tmp/test.txt', 'Hey there!')
For a complete reference, check the outputFile
documentation and all node-fs-extra supported methods.
The pyaudio website has many examples that are pretty short and clear: http://people.csail.mit.edu/hubert/pyaudio/
Update 14th of December 2019 - Main example from the above linked website from 2017:
"""PyAudio Example: Play a WAVE file."""
import pyaudio
import wave
import sys
CHUNK = 1024
if len(sys.argv) < 2:
print("Plays a wave file.\n\nUsage: %s filename.wav" % sys.argv[0])
sys.exit(-1)
wf = wave.open(sys.argv[1], 'rb')
p = pyaudio.PyAudio()
stream = p.open(format=p.get_format_from_width(wf.getsampwidth()),
channels=wf.getnchannels(),
rate=wf.getframerate(),
output=True)
data = wf.readframes(CHUNK)
while data != '':
stream.write(data)
data = wf.readframes(CHUNK)
stream.stop_stream()
stream.close()
p.terminate()
Another possibility is to use regular expressions which is what Perl is famous for:
if ($mystring =~ /s1\.domain\.com/) {
print qq("$mystring" contains "s1.domain.com"\n);
}
The backslashes are needed because a .
can match any character. You can get around this by using the \Q
and \E
operators.
my $substring = "s1.domain.com";
if ($mystring =~ /\Q$substring\E/) {
print qq("$mystring" contains "$substring"\n);
}
Or, you can do as eugene y stated and use the index function.
Just a word of warning: Index returns a -1
when it can't find a match instead of an undef
or 0
.
Thus, this is an error:
my $substring = "s1.domain.com";
if (not index($mystring, $substr)) {
print qq("$mystring" doesn't contains "$substring"\n";
}
This will be wrong if s1.domain.com
is at the beginning of your string. I've personally been burned on this more than once.
If you installed postresql on your server then just host: localhost to database.yml, I usually throw it in around where it says pool: 5. Otherwise if it's not localhost definitely tell that app where to find its database.
development:
adapter: postgresql
encoding: unicode
database: kickrstack_development
host: localhost
pool: 5
username: kickrstack
password: secret
Make sure your user credentials are set correctly by creating a database and assigning ownership to your app's user to establish the connection. To create a new user in postgresql 9 run:
sudo -u postgres psql
set the postgresql user password if you haven't, it's just backslash password.
postgres=# \password
Create a new user and password and the user's new database:
postgres=# create user "guy_on_stackoverflow" with password 'keepitonthedl';
postgres=# create database "dcaclab_development" owner "guy_on_stackoverflow";
Now update your database.yml file after you've confirmed creating the database, user, password and set these privileges. Don't forget host: localhost.
As per the maven's documentation, there are two possible settings.xml locations
One is the global maven's repo (Your initial download and subsequent unzipped files from apache maven) $M2_HOME/conf/settings.xml
And the second is the user created one (Your local copy) ${user.home}/.m2/settings.xml
The local copy takes precedence over the global copy in terms of settings information. But it is said that they both get merged during "runtime". If you need to have your local copy of the settings.xml, simply copy from the global copy and paste in your .m2 folder and adjust the details as needed
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
To upload files to your repo without using the command-line, simply type this after your repository name in the browser:
https://github.com/yourname/yourrepositoryname/upload/master
and then drag and drop your files.(provided you are on github and the repository has been created beforehand)
I solved this, without having to completely reinstall Visual Studio 2013.
For those who may come across this in the future, the following steps worked for me:
vs_professional.exe
).If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3
Click the link for 'examine the log file' and look near the bottom of the log, for this line:
open regedit.exe
and do an Edit > Find...
for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}
. This was found in:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}
Edit the BundleVersion
value and change it to a lower version. I changed mine from 12.0.21005.13
to 12.0.21000.13
:
Exit the registry
Run the ISO (or vs_professional.exe
) again. If it has a repair button like the image below, you can skip to step 4.
Run the ISO (or vs_professional.exe
) again. This time repair should be visible.
Click Repair
and let it update your installation and apply its embedded license key. This took about 20 minutes.
Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product
:
Hope this helps somebody in the future!
You should only be pushing to a bare repository. A bare repository is a repository that has no checked out branches. If you were to cd to a bare repository directory, you'd only see the contents of a .git directory.
Not sure if you're talking about Coverflow (scroll through images) or Quicklook (preview files in lightbox), try editing your question.
Here's some JS Coverflow implementations:
in IE you can get the event object by window.event
in other browsers with no 'use strict'
directive, it is possible to get by arguments.callee.caller.arguments[0]
.
function myFunc(p1, p2, p3) {
var evt = window.event || arguments.callee.caller.arguments[0];
}
Add following lines after finish();
in onDestroy()
:
android.os.Process.killProcess(android.os.Process.myPid());
super.onDestroy();
I have just started checking out Angular(so im quite sure there are other ways to get it done which are more optimum), and i came across this question while searching for examples of ng-repeat.
The requirement by the poser(with the update):
"...but my real requirement is display the items as shown below.."
looked real-world enough (and simple), so i thought ill give it a spin and attempt to get the exact desired structure.
angular.module('appTest', [])_x000D_
.controller("repeatCtrl", function($scope) {_x000D_
$scope.items = [{_x000D_
Name: "Soap",_x000D_
Price: "25",_x000D_
Quantity: "10"_x000D_
}, {_x000D_
Name: "Bag",_x000D_
Price: "100",_x000D_
Quantity: "15"_x000D_
}, {_x000D_
Name: "Pen",_x000D_
Price: "15",_x000D_
Quantity: "13"_x000D_
}];_x000D_
})
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
_x000D_
<body ng-app="appTest">_x000D_
<section ng-controller="repeatCtrl">_x000D_
<table>_x000D_
<thead>_x000D_
<tr ng-repeat="item in items | limitTo:1">_x000D_
<th ng-repeat="(key, val) in item">_x000D_
{{key}}_x000D_
</th>_x000D_
</tr>_x000D_
</thead>_x000D_
<tbody>_x000D_
<tr ng-repeat="item in items">_x000D_
<td ng-repeat="(key, val) in item">_x000D_
{{val}}_x000D_
</td>_x000D_
</tr>_x000D_
</tbody>_x000D_
</table>_x000D_
</section>_x000D_
</body>
_x000D_
The limitTo:(n) filter is the key. Im still not sure if having multiple ng-repeat is an optimum way to go about it, but can't think of another alternative currently.
ES6 approach...
Imagine you have this object below:
const developers = {
1: {
id: 1,
name: "Brendan",
family: "Eich"
},
2: {
id: 2,
name: "John",
family: "Resig"
},
3: {
id: 3,
name: "Alireza",
family: "Dezfoolian"
}
};
Create a function:
const filterObject = (obj, filter, filterValue) =>
Object.keys(obj).reduce((acc, val) =>
(obj[val][filter] === filterValue ? acc : {
...acc,
[val]: obj[val]
}
), {});
And call it:
filterObject(developers, "name", "Alireza");
and will return:
{
1: {
id: 1,
name: "Brendan",
family: "Eich"
},
2: {
id: 2,
name: "John",
family: "Resig"
}
}
If you do not want to include the jquery library you can simple do the following
a) ad an iframe, size 0px so it is not visible, href is blank
b) execute this within your js code function
window.frames['iframename'].location.replace('http://....your.php');
This will execute the php script and you can for example make a database update...
I figured out myself.
cmp
calls ComputeBetasAndNuHat
which returns a list which has objective
as minusloglik
So I can change the function cmp
to get this value.
You have created a factor variable in nm
so you either need to avoid doing so or add an additional level to the factor attributes. You should also avoid using <-
in the arguments to data.frame()
Option 1:
junk <- data.frame(x = rep(LETTERS[1:4], 3), y =letters[1:12], stringsAsFactors=FALSE)
junk$nm[junk$nm == "B"] <- "b"
Option 2:
levels(junk$nm) <- c(levels(junk$nm), "b")
junk$nm[junk$nm == "B"] <- "b"
junk
arrayData.forEach((key : any, val: any) => {
key['index'] = val + 1;
arrayData2.forEach((keys : any, vals :any) => {
if (key.group_id == keys.id) {
key.group_name = keys.group_name;
}
})
})

If you're leveraging React Hooks, you can take advantage of the useHistory
API that comes from React Router v5.
import React, {useCallback} from 'react';
import {useHistory} from 'react-router-dom';
export default function StackOverflowExample() {
const history = useHistory();
const handleOnClick = useCallback(() => history.push('/sample'), [history]);
return (
<button type="button" onClick={handleOnClick}>
Go home
</button>
);
}
Another way to write the click handler if you don't want to use useCallback
const handleOnClick = () => history.push('/sample');
The v4 recommended way is to allow your render method to catch a redirect. Use state or props to determine if the redirect component needs to be shown (which then trigger's a redirect).
import { Redirect } from 'react-router';
// ... your class implementation
handleOnClick = () => {
// some action...
// then redirect
this.setState({redirect: true});
}
render() {
if (this.state.redirect) {
return <Redirect push to="/sample" />;
}
return <button onClick={this.handleOnClick} type="button">Button</button>;
}
Reference: https://reacttraining.com/react-router/web/api/Redirect
You can also take advantage of Router
's context that's exposed to the React component.
static contextTypes = {
router: PropTypes.shape({
history: PropTypes.shape({
push: PropTypes.func.isRequired,
replace: PropTypes.func.isRequired
}).isRequired,
staticContext: PropTypes.object
}).isRequired
};
handleOnClick = () => {
this.context.router.push('/sample');
}
This is how <Redirect />
works under the hood.
If you still need to do something similar to v2's implementation, you can create a copy of BrowserRouter
then expose the history
as an exportable constant. Below is a basic example but you can compose it to inject it with customizable props if needed. There are noted caveats with lifecycles, but it should always rerender the Router, just like in v2. This can be useful for redirects after an API request from an action function.
// browser router file...
import createHistory from 'history/createBrowserHistory';
import { Router } from 'react-router';
export const history = createHistory();
export default class BrowserRouter extends Component {
render() {
return <Router history={history} children={this.props.children} />
}
}
// your main file...
import BrowserRouter from './relative/path/to/BrowserRouter';
import { render } from 'react-dom';
render(
<BrowserRouter>
<App/>
</BrowserRouter>
);
// some file... where you don't have React instance references
import { history } from './relative/path/to/BrowserRouter';
history.push('/sample');
Latest BrowserRouter
to extend: https://github.com/ReactTraining/react-router/blob/master/packages/react-router-dom/modules/BrowserRouter.js
Push a new state to the browserHistory
instance:
import {browserHistory} from 'react-router';
// ...
browserHistory.push('/sample');
Reference: https://github.com/reactjs/react-router/blob/master/docs/guides/NavigatingOutsideOfComponents.md
You do something like this:
{{ dateObj | date:'shortDate' }}
or
{{ dateObj | date:'ddmmy' }}
See: https://angular.io/docs/ts/latest/api/common/index/DatePipe-pipe.html
Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load
from the dropdown.
A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);
A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!
for iterating through JSON you can use this:
json_object = json.loads(json_file)
for element in json_object:
for value in json_object['Name_OF_YOUR_KEY/ELEMENT']:
print(json_object['Name_OF_YOUR_KEY/ELEMENT']['INDEX_OF_VALUE']['VALUE'])
I am using XPathSelectElements
extension method which works in the same way to XmlDocument.SelectNodes
method:
using System;
using System.Xml.Linq;
using System.Xml.XPath; // for XPathSelectElements
namespace testconsoleApp
{
class Program
{
static void Main(string[] args)
{
XDocument xdoc = XDocument.Parse(
@"<root>
<child>
<name>john</name>
</child>
<child>
<name>fred</name>
</child>
<child>
<name>mark</name>
</child>
</root>");
foreach (var childElem in xdoc.XPathSelectElements("//child"))
{
string childName = childElem.Element("name").Value;
Console.WriteLine(childName);
}
}
}
}
Ideally you would put that in a directive, but you can also just put it in the controller. http://jsfiddle.net/tnq86/15/
angular.module('App', [])
.controller('AppCtrl', function ($scope) {
$scope.model = 0;
$scope.initSlider = function () {
$(function () {
// wait till load event fires so all resources are available
$scope.$slider = $('#slider').slider({
slide: $scope.onSlide
});
});
$scope.onSlide = function (e, ui) {
$scope.model = ui.value;
$scope.$digest();
};
};
$scope.initSlider();
});
The directive approach:
HTML
<div slider></div>
JS
angular.module('App', [])
.directive('slider', function (DataModel) {
return {
restrict: 'A',
scope: true,
controller: function ($scope, $element, $attrs) {
$scope.onSlide = function (e, ui) {
$scope.model = ui.value;
// or set it on the model
// DataModel.model = ui.value;
// add to angular digest cycle
$scope.$digest();
};
},
link: function (scope, el, attrs) {
var options = {
slide: scope.onSlide
};
// set up slider on load
angular.element(document).ready(function () {
scope.$slider = $(el).slider(options);
});
}
}
});
I would also recommend checking out Angular Bootstrap's source code: https://github.com/angular-ui/bootstrap/blob/master/src/tooltip/tooltip.js
You can also use a factory to create the directive. This gives you ultimate flexibility to integrate services around it and whatever dependencies you need.
You get this error when declaring a forward reference inside the wrong namespace thus declaring a new type without defining it. For example:
namespace X
{
namespace Y
{
class A;
void func(A* a) { ... } // incomplete type here!
}
}
...but, in class A was defined like this:
namespace X
{
class A { ... };
}
Thus, A was defined as X::A
, but I was using it as X::Y::A
.
The fix obviously is to move the forward reference to its proper place like so:
namespace X
{
class A;
namespace Y
{
void func(X::A* a) { ... } // Now accurately referencing the class`enter code here`
}
}
just run DBCC useroptions
and you'll get something like this:
Set Option Value

If you're OK with littering your markup a bit, you could do it the easy way and just wrap your <button>
with an anchor (<a>
) link.
<a href="#/new-page.html"><button>New Page<button></a>
Also, there is nothing stopping you from styling an anchor link to look like a <button>
as pointed out in the comments by @tronman, this is not technically valid html5, but it should not cause any problems in practice
In brief:
DateFormat formatter = new SimpleDateFormat("MM/dd/yy");
try {
Date date = formatter.parse("01/29/02");
} catch (ParseException e) {
e.printStackTrace();
}
See SimpleDateFormat
javadoc for more.
And to turn it into a Calendar
, do:
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
I think you're almost there.
The thing is, your $(this)
in the "close button" listener is not the clickable div. So you want to search it first. try to replace $(this)
with $(this).closest(".clickable")
. And don't forget the e.stopPropagation()
as Guilherme is suggesting. that should be something like:
$( document ).ready(function() {
$(document).on("click", ".close_button", function () {
alert ("oi");
e.stopPropagation()
$(this).closest(".clickable").addClass("spot");
$(this).closest(".clickable").removeClass("grown");
});
$(document).on("click", ".clickable", function () {
if ($(this).hasClass("spot")){
$(this).addClass("grown");
$(this).removeClass("spot");
}
});
});
Just in case if you are using Telerik components and you have a reference in your javascript with <%= .... %> then wrap your script tag with a RadScriptBlock.
<telerik:RadScriptBlock ID="radSript1" runat="server">
<script type="text/javascript">
//Your javascript
</script>
</telerik>

Firstly in general tab -> signing section -> select a development team, manage signings
Similarly if you are working with multiple pod files select each pod target separately and go to general tab -> signing section -> select a development team, manage signings
repeat the same process for all pods in your project
Clean -> Build the project.
This worked for me
The ~/Library/Developer/Xcode/iOS DeviceSupport
folder is basically only needed to symbolicate crash logs.
You could completely purge the entire folder. Of course the next time you connect one of your devices, Xcode would redownload the symbol data from the device.
I clean out that folder once a year or so by deleting folders for versions of iOS I no longer support or expect to ever have to symbolicate a crash log for.
I've been using some simple CSS and it seems to remove them and work fine.

I just want to add my 2 cents. I had the same goal (to change the background color from the .java class). But none of the above methods worked for me.
Issue was, that I set the background color inside the layout .xml file with android:background="@color/colorGray"
:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/colorGray">
So I just deleted particular line:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
Now I (you) can set the color from the code with:
getWindow().getDecorView().setBackgroundColor(Color.GRAY);
I solved it this way:
Process proc = new Process();
proc.StartInfo.FileName = batchFile;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.RedirectStandardInput = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.Start();
StreamWriter streamWriter = proc.StandardInput;
StreamReader outputReader = proc.StandardOutput;
StreamReader errorReader = proc.StandardError;
while (!outputReader.EndOfStream)
{
string text = outputReader.ReadLine();
streamWriter.WriteLine(text);
}
while (!errorReader.EndOfStream)
{
string text = errorReader.ReadLine();
streamWriter.WriteLine(text);
}
streamWriter.Close();
proc.WaitForExit();
I redirected both input, output and error and handled reading from output and error streams. This solution works for SDK 7- 8.1, both for Windows 7 and Windows 8
I have written a small example for detecting vertical and horizontal shakes and showing a Toast
.
public class Accelerometerka2Activity extends Activity implements SensorEventListener {
private float mLastX, mLastY, mLastZ;
private boolean mInitialized;
private SensorManager mSensorManager;
private Sensor mAccelerometer;
private final float NOISE = (float) 8.0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mInitialized = false;
mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
mSensorManager.registerListener(this, mAccelerometer , SensorManager.SENSOR_DELAY_NORMAL);
}
protected void onResume() {
super.onResume();
mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
}
protected void onPause() {
super.onPause();
mSensorManager.unregisterListener(this);
}
public void onAccuracyChanged(Sensor sensor, int accuracy) {
// can be safely ignored for this demo
}
public void onSensorChanged(SensorEvent event) {
float x = event.values[0];
float y = event.values[1];
float z = event.values[2];
if (!mInitialized) {
mLastX = x;
mLastY = y;
mLastZ = z;
mInitialized = true;
} else {
float deltaX = Math.abs(mLastX - x);
float deltaY = Math.abs(mLastY - y);
float deltaZ = Math.abs(mLastZ - z);
if (deltaX < NOISE) deltaX = (float)0.0;
if (deltaY < NOISE) deltaY = (float)0.0;
if (deltaZ < NOISE) deltaZ = (float)0.0;
mLastX = x;
mLastY = y;
mLastZ = z;
if (deltaX > deltaY) {
Toast.makeText(getBaseContext(), "Horizental", Toast.LENGTH_SHORT).show();
} else if (deltaY > deltaX) {
Toast.makeText(getBaseContext(), "Vertical", Toast.LENGTH_SHORT).show();
}
}
}
}
It might be an easiest way-
String recipientList = mEditTextTo.getText().toString();
String[] recipients = recipientList.split(",");
String subject = mEditTextSubject.getText().toString();
String message = mEditTextMessage.getText().toString();
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_EMAIL, recipients);
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_TEXT, message);
intent.setType("message/rfc822");
startActivity(Intent.createChooser(intent, "Choose an email client"));
Surround what you want to be bold with:
<span style="font-weight:bold">Your bold text</span>
This would go inside your <td>
tag.
Use
df[df['id']==x].index.tolist()
If x
is present in id
then it'll return the list of indices where it is present, else it gives an empty list.
The full list is:
DB, DW, DD, DQ, DT, DDQ, and DO (used to declare initialized data in the output file.)
See: http://www.tortall.net/projects/yasm/manual/html/nasm-pseudop.html
They can be invoked in a wide range of ways: (Note: for Visual-Studio - use "h" instead of "0x" syntax - eg: not 0x55 but 55h instead):
db 0x55 ; just the byte 0x55
db 0x55,0x56,0x57 ; three bytes in succession
db 'a',0x55 ; character constants are OK
db 'hello',13,10,'$' ; so are string constants
dw 0x1234 ; 0x34 0x12
dw 'A' ; 0x41 0x00 (it's just a number)
dw 'AB' ; 0x41 0x42 (character constant)
dw 'ABC' ; 0x41 0x42 0x43 0x00 (string)
dd 0x12345678 ; 0x78 0x56 0x34 0x12
dq 0x1122334455667788 ; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
ddq 0x112233445566778899aabbccddeeff00
; 0x00 0xff 0xee 0xdd 0xcc 0xbb 0xaa 0x99
; 0x88 0x77 0x66 0x55 0x44 0x33 0x22 0x11
do 0x112233445566778899aabbccddeeff00 ; same as previous
dd 1.234567e20 ; floating-point constant
dq 1.234567e20 ; double-precision float
dt 1.234567e20 ; extended-precision float
DT does not accept numeric constants as operands, and DDQ does not accept float constants as operands. Any size larger than DD does not accept strings as operands.
First of all Assert()
method is available for Trace
and Debug
classes.
Debug.Assert()
is executing only in Debug mode.
Trace.Assert()
is executing in Debug and Release mode.
Here is an example:
int i = 1 + 3;
// Debug.Assert method in Debug mode fails, since i == 4
Debug.Assert(i == 3);
Debug.WriteLine(i == 3, "i is equal to 3");
// Trace.Assert method in Release mode is not failing.
Trace.Assert(i == 4);
Trace.WriteLine(i == 4, "i is equla to 4");
Console.WriteLine("Press a key to continue...");
Console.ReadLine();
Run this code in Debug mode and then in Release mode.
You will notice that during Debug mode your code Debug.Assert
statement fails, you get a message box showing the current stack trace of the application. This is not happening in Release mode since Trace.Assert()
condition is true (i == 4)
.
WriteLine()
method simply gives you an option of logging the information to Visual Studio output.
Silverlight applications do not have direct access to machine.config.
Do this:
$( '#wrapper' ).on( 'click', 'a', function () { ... });
where #wrapper
is a static element in which you add the dynamic links.
So, you have a wrapper which is hard-coded into the HTML source code:
<div id="wrapper"></div>
and you fill it with dynamic content. The idea is to delegate the events to that wrapper, instead of binding handlers directly on the dynamic elements.
Btw, I recommend Backbone.js - it gives structure to this process:
var YourThing = Backbone.View.extend({
// the static wrapper (the root for event delegation)
el: $( '#wrapper' ),
// event bindings are defined here
events: {
'click a': 'anchorClicked'
},
// your DOM event handlers
anchorClicked: function () {
// handle click event
}
});
new YourThing; // initializing your thing
You probably want git checkout master
, or git checkout [branchname]
.
That's a very complex question for a simple answer.
You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.
Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.
At the very top level I think quality REST API docs require at least the following:
Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.
A good alternative is this:
find . -type f | xargs chmod -v 644
and for directories:
find . -type d | xargs chmod -v 755
and to be more explicit:
find . -type f | xargs -I{} chmod -v 644 {}
The rubocop gem contributors propose in their Ruby Style Guide:
Prefer alias when aliasing methods in lexical class scope as the resolution of self in this context is also lexical, and it communicates clearly to the user that the indirection of your alias will not be altered at runtime or by any subclass unless made explicit.
class Westerner
def first_name
@names.first
end
alias given_name first_name
end
Always use alias_method when aliasing methods of modules, classes, or singleton classes at runtime, as the lexical scope of alias leads to unpredictability in these cases
module Mononymous
def self.included(other)
other.class_eval { alias_method :full_name, :given_name }
end
end
class Sting < Westerner
include Mononymous
end
As Dirk said, the function you are after is 'read.csv' or one of the other read.table variants. Given your sample data above, I think you will want to do something like this:
setwd("c:/random/directory")
df <- read.csv("myRandomFile.csv", header=TRUE)
All we did in the above was set the directory to where your .csv file is and then read the .csv into a dataframe named df. You can check that the data loaded properly by checking the structure of the object with:
str(df)
Assuming the data loaded properly, you can think go on to perform any number of statistical methods with the data in your data frame. I think summary(df)
would be a good place to start. Learning how to use the help in R will be immensely useful, and a quick read through the help on CRAN will save you lots of time in the future: http://cran.r-project.org/
There is nothing inherently wrong with the pattern, assuming it is being used for some aspect of your model which is truly single.
I believe the backlash is due to its overuse which, in turn, is due to the fact that it's the easiest pattern to understand and implement.
You can use $inject service to inject a service in you config
app.config(function($provide){ $provide.decorator("$exceptionHandler", function($delegate, $injector){ return function(exception, cause){ var $rootScope = $injector.get("$rootScope"); $rootScope.addError({message:"Exception", reason:exception}); $delegate(exception, cause); }; }); });

Here's another approach:
def my_func(arg1, arg2, arg3):
... so something ...
kwargs = {'arg1': 'Value One', 'arg2': 'Value Two', 'arg3': 'Value Three'}
# Now you can call the function with kwargs like this:
my_func(**kwargs)
You should include json
in your file
For Example,
require 'json'
your_hash = {one: "1", two: "2"}
your_hash.to_json

First, you need to create a personal access token (PAT). This is described here: https://help.github.com/articles/creating-an-access-token-for-command-line-use/
Laughably, the article tells you how to create it, but gives absolutely no clue what to do with it. After about an hour of trawling documentation and Stack Overflow, I finally found the answer:
$ git clone https://github.com/user-or-organisation/myrepo.git
Username: <my-username>
Password: <my-personal-access-token>
I was actually forced to enable two-factor authentication by company policy while I was working remotely and still had local changes, so in fact it was not clone
I needed, but push
. I read in lots of places that I needed to delete and recreate the remote, but in fact my normal push
command worked exactly the same as the clone
above, and the remote did not change:
$ git push https://github.com/user-or-organisation/myrepo.git
Username: <my-username>
Password: <my-personal-access-token>
(@YMHuang put me on the right track with the documentation link.)
These error meassages
1.For the Visual Studio compiler: error C2065: 'printf' : undeclared identifier
2.For the GCC compiler: `printf' undeclared (first use in this function)
mean that you use name printf
but the compiler does not see where the name was declared and accordingly does not know what it means.
Any name used in a program shall be declared before its using. The compiler has to know what the name denotes.
In this particular case the compiler does not see the declaration of name printf
. As we know (but not the compiler) it is the name of standard C function declared in header <stdio.h>
in C or in header <cstdio>
in C++ and placed in standard (std::
) and global (::
) (not necessarily) name spaces.
So before using this function we have to provide its name declaration to the compiler by including corresponding headers.
For example C:
#include <stdio.h>
int main( void )
{
printf( "Hello World\n" );
}
C++:
#include <cstdio>
int main()
{
std::printf( "Hello World\n" );
// or printf( "Hello World\n" );
// or ::printf( "Hello World\n" );
}
Sometimes the reason of such an error is a simple typo. For example let's assume that you defined function PrintHello
void PrintHello()
{
std::printf( "Hello World\n" );
}
but in main you made a typo and instead of PrintHello
you typed printHello
with lower case letter 'p'.
#include <cstdio>
void PrintHello()
{
std::printf( "Hello World\n" );
}
int main()
{
printHello();
}
In this case the compiler will issue such an error because it does not see the declaration of name printHello
. PrintHello
and printHello
are two different names one of which was declared and other was not declared but used in the body of main
I found the following to work on Chrome, Firefox and IE11:
$('iframe').load(function () {
$('iframe').height($('iframe').contents().height());
});
When the Iframes content is done loading the event will fire and it will set the IFrames height to that of its content. This will only work for pages within the same domain as that of the IFrame.
What you've got (according to the debug image) is an object array containing a string array. So you need something like:
Object[] objects = (Object[]) values;
String[] strings = (String[]) objects[0];
You haven't shown the type of values
- if this is already Object[]
then you could just use (String[])values[0]
.
Of course even with the cast to Object[]
you could still do it in one statement, but it's ugly:
String[] strings = (String[]) ((Object[])values)[0];
You can also do this in the Visual Studio debugger without modifying the code.
Of course, this doesn't help if you're running the code on a different machine, but it can be quite handy to be able to spit out a stack trace automatically without affecting release code or without even needing to restart the program.
If you round 8.8333333333339 to 2 decimals, the correct answer is 8.83, not 8.84. The reason you got 8.83000000001 is because 8.83 is a number that cannot be correctly reprecented in binary, and it gives you the closest one. If you want to print it without all the zeros, do as VGE says:
print "%.2f" % 8.833333333339 #(Replace number with the variable?)
This is a feature, not a bug.
See http://docs.python.org/howto/unicode.html, specifically the 'unicode type' section.
This is the best way, I know of to create dynamic variables in python.
my_dict = {}
x = "Buffalo"
my_dict[x] = 4
I found a similar, but not the same question here Creating dynamically named variables from user input
The linked list holds operations on the shared data structure.
For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).
In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.
In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.
There's another way that works if you don't mind only targeting newer browsers. Just add the CSS
pointer-events: none;
to any children of the div you want to capture the click. Here's the support tables
Assuming the iFrame has a name attribute of "myIframe":
<a href="http://www.google.com" target="myIframe">Link Text</a>
You can also accomplish this with the use of Javascript. The iFrame has a src attribute which specifies the location it shows. As such, it's a simple matter of binding the click of a link to changing that src attribute.
If you want to modify only the first commit, you may try git rebase and amend the commit, which is similar to this post: How to modify a specified commit in git?
And if you want to modify all the commits which contain the raw email, filter-branch is the best choice. There is an example of how to change email address globally on the book Pro Git, and you may find this link useful http://git-scm.com/book/en/Git-Tools-Rewriting-History

this.user = ({} as USER)
If you just need the name of the device here is a little hack which i wrote in bash. To run it in python you need the following snippet. Just replace $1 and $2 with Bus number and Device number eg 001 or 002.
import os
os.system("lsusb | grep \"Bus $1 Device $2\" | sed 's/\// /' | awk '{for(i=7;i<=NF;++i)print $i}'")
Alternately you can save it as a bash script and run it from there too. Just save it as a bash script like foo.sh make it executable.
#!/bin/bash
myvar=$(lsusb | grep "Bus $1 Device $2" | sed 's/\// /' | awk '{for(i=7;i<=NF;++i)print $i}')
echo $myvar
Then call it in python script as
import os
os.system('foo.sh')
You can ignore the URL field and simply paste the viewstate into the Viewstate string box.
It does look like you have an old version; the serialisation methods changed in ASP.NET 2.0, so grab the 2.0 version
The correct character to use in this case is a full colon (:
), not a semicolon (;
).

The issue HttpServletRequest.login does not set authentication state in session has been fixed in 3.0.1. Update glassfish to the latest version and you're done.
Updating is quite straightforward:

glassfishv3/bin/pkg image-update
Yes, once the return
statement is executed, the entire function is exited at that very point.
Just imagine what would happen if it did not and continued looping, and executing that return
statement each time? It would invalidate it's meaning of returning a value when you think about it.
Try Request.Url.Query
if you want the raw querystring as a string.
Try this:

Did you try:
$DBH = new PDO( "connection string goes here" );
$row = $DBH->query( "select figure from table1" )->fetch();
echo $row["figure"];
$DBH = null;
To achieve it, you have to modify the background-color
of the element.
Ways to create a (semi-) transparent color:
The CSS color name transparent
creates a completely transparent color.
Usage:
.transparent{
background-color: transparent;
}
Using rgba
or hsla
color functions, that allow you to add the alpha channel (opacity) to the rgb
and hsl
functions. Their alpha values range from 0 - 1.
Usage:
.semi-transparent-yellow{
background-color: rgba(255, 255, 0, 0.5);
}
.transparent{
background-color: hsla(0, 0%, 0%, 0);
}
Besides the already mentioned solutions, you can also use the HEX format with alpha value (#RRGGBBAA
or #RGBA
notation).
That's pretty new (contained by CSS Color Module Level 4), but already implemented in larger browsers (sorry, no IE).
This differs from the other solutions, as this treats the alpha channel (opacity) as a hexadecimal value as well, making it range from 0 - 255 (FF
).
Usage:
.semi-transparent-yellow{
background-color: #FFFF0080;
}
.transparent{
background-color: #0000;
}
You can try them out as well:
transparent

Lets define the dataframe from your example by
>>> df = pd.DataFrame([[206, 214], [226, 234], [245, 253], [265, 272], [283, 291]],
columns=[1, 2])
>>> df
1 2
0 206 214
1 226 234
2 245 253
3 265 272
4 283 291
Then you could manipulate the index of the second column by
>>> df[2].index = df[2].index+1
and finally re-combine the single columns
>>> pd.concat([df[1], df[2]], axis=1)
1 2
0 206.0 NaN
1 226.0 214.0
2 245.0 234.0
3 265.0 253.0
4 283.0 272.0
5 NaN 291.0
Perhaps not fast but simple to read. Consider setting variables for the column names and the actual shift required.
Edit: Generally shifting is possible by df[2].shift(1)
as already posted however would that cut-off the carryover.
The problem here is that the "on" is applied to all elements that exists AT THE TIME. When you create an element dynamically, you need to run the on again:
$('form').on('submit',doFormStuff);
createNewForm();
// re-attach to all forms
$('form').off('submit').on('submit',doFormStuff);
Since forms usually have names or IDs, you can just attach to the new form as well. If I'm creating a lot of dynamic stuff, I'll include a setup or bind function:
function bindItems(){
$('form').off('submit').on('submit',doFormStuff);
$('button').off('click').on('click',doButtonStuff);
}
So then whenever you create something (buttons usually in my case), I just call bindItems to update everything on the page.
createNewButton();
bindItems();
I don't like using 'body' or document elements because with tabs and modals they tend to hang around and do things you don't expect. I always try to be as specific as possible unless its a simple 1 page project.
If you know the structure of the json that you're receiving then I'd suggest having a class structure that mirrors what you're receiving in json.
Then you can call its something like this...
AddressMap addressMap = JsonConvert.DeserializeObject<AddressMap>(json);
(Where json is a string containing the json in question)
If you don't know the format of the json you've receiving then it gets a bit more complicated and you'd probably need to manually parse it.

There's also the rotateY
for a real mirror one:
transform: rotateY(180deg);
Which, perhaps, is even more clear and understandable.
EDIT: Doesn't seem to work on Opera though… sadly. But it works fine on Firefox. I guess it might required to implicitly say that we are doing some kind of translate3d

Note: All of the following instructions apply universally (aka to all OSes) unless otherwise specified.
You will need:
Change the file extension of the .apk
file by either adding a .zip
extension to the filename, or to change .apk
to .zip
.
For example, com.example.apk
becomes com.example.zip
, or com.example.apk.zip
. Note that on Windows and macOS, it may prompt you whether you are sure you want to change the file extension. Click OK or Add if you're using macOS:
Extract the renamed APK file in a specific folder. For example, let that folder be demofolder
.
If it didn't work, try opening the file in another application such as WinZip or 7-Zip.
For macOS, you can try running unzip
in Terminal (available at /Applications/Terminal.app
), where it takes one or more arguments: the file to unzip + optional arguments. See man unzip
for documentation and arguments.
Download dex2jar
(see all releases on GitHub) and extract that zip file in the same folder as stated in the previous point.
Open command prompt (or a terminal) and change your current directory to the folder created in the previous point and type the command d2j-dex2jar.bat classes.dex
and press enter. This will generate classes-dex2jar.jar
file in the same folder.
d2j-dex2jar.bat
with d2j-dex2jar.sh
. In other words, run d2j-jar2dex.sh classes.dex
in the terminal and press enter.Download Java Decompiler (see all releases on Github) and extract it and start (aka double click) the executable/application.
From the JD-GUI window, either drag and drop the generated classes-dex2jar.jar
file into it, or go to File > Open File...
and browse for the jar.
Next, in the menu, go to File > Save All Sources
(Windows: Ctrl+Alt+S, macOS: ?+?+S). This should open a dialog asking you where to save a zip file named `classes-dex2jar.jar.src.zip" consisting of all packages and java files. (You can rename the zip file to be saved)
Extract that zip file (classes-dex2jar.jar.src.zip
) and you should get all java files of the application.
xml
files from APKapktool
website for installation instructions and moreWindows:
myxmlfolder
).myxmlfolder
folder and rename the apktool jar file to apktool.jar
..apk
file in the same folder (i.e myxmlfolder
).Open the command prompt (or terminal) and change your current directory to the folder where apktool
is stored (in this case, myxmlfolder
). Next, type the command apktool if framework-res.apk
.
What we're doing here is that we are installing a framework. For more info, see the docs.
In the command prompt, type the command apktool d filename.apk
(where filename
is the name of apk file). This should decode the file. For more info, see the docs.
This should result in a folder filename.out
being outputted, where filename
is the original name of the apk file without the .apk
file extension. In this folder are all the XML files such as layout, drawables etc.

If you want nice validation popups and images when an error occurs you can use the setError

You have to move the css
folder into your web
folder. It seems that your web
folder on the hard drive equals the /ServletApp
folder as seen from the www. Other content than inside your web
folder cannot be accessed from the browsers.
The url of the CSS link is then
<link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css"/>
The accepted answer is the correct way to do this in most cases. However, there are some situations where you want to set the cookie header manually. Normally if you set a "Cookie" header it is ignored, but that's because HttpClientHandler
defaults to using its CookieContainer
property for cookies. If you disable that then by setting UseCookies
to false
you can set cookie headers manually and they will appear in the request, e.g.
var baseAddress = new Uri("http://example.com");
using (var handler = new HttpClientHandler { UseCookies = false })
using (var client = new HttpClient(handler) { BaseAddress = baseAddress })
{
var message = new HttpRequestMessage(HttpMethod.Get, "/test");
message.Headers.Add("Cookie", "cookie1=value1; cookie2=value2");
var result = await client.SendAsync(message);
result.EnsureSuccessStatusCode();
}

Vectors and matrices can only be of a single type and cbind
and rbind
on vectors will give matrices. In these cases, the numeric values will be promoted to character values since that type will hold all the values.
(Note that in your rbind
example, the promotion happens within the c
call:
> c(10, "[]", "[[1,2]]")
[1] "10" "[]" "[[1,2]]"
If you want a rectangular structure where the columns can be different types, you want a data.frame
. Any of the following should get you what you want:
> x = data.frame(v1=c(10, 20), v2=c("[]", "[]"), v3=c("[[1,2]]","[[1,3]]"))
> x
v1 v2 v3
1 10 [] [[1,2]]
2 20 [] [[1,3]]
> str(x)
'data.frame': 2 obs. of 3 variables:
$ v1: num 10 20
$ v2: Factor w/ 1 level "[]": 1 1
$ v3: Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2
or (using specifically the data.frame
version of cbind
)
> x = cbind.data.frame(c(10, 20), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
c(10, 20) c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1 10 [] [[1,2]]
2 20 [] [[1,3]]
> str(x)
'data.frame': 2 obs. of 3 variables:
$ c(10, 20) : num 10 20
$ c("[]", "[]") : Factor w/ 1 level "[]": 1 1
$ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2
or (using cbind
, but making the first a data.frame
so that it combines as data.frames do):
> x = cbind(data.frame(c(10, 20)), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
c.10..20. c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1 10 [] [[1,2]]
2 20 [] [[1,3]]
> str(x)
'data.frame': 2 obs. of 3 variables:
$ c.10..20. : num 10 20
$ c("[]", "[]") : Factor w/ 1 level "[]": 1 1
$ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2
Use the $_SERVER['HTTP_REFERER']

Try closing Android Studio/Eclipse if it's open. It worked for me.
As of the current JRE implementation, Function.identity()
will always return the same instance while each occurrence of identifier -> identifier
will not only create its own instance but even have a distinct implementation class. For more details, see here.
The reason is that the compiler generates a synthetic method holding the trivial body of that lambda expression (in the case of x->x
, equivalent to return identifier;
) and tell the runtime to create an implementation of the functional interface calling this method. So the runtime sees only different target methods and the current implementation does not analyze the methods to find out whether certain methods are equivalent.
So using Function.identity()
instead of x -> x
might save some memory but that shouldn’t drive your decision if you really think that x -> x
is more readable than Function.identity()
.
You may also consider that when compiling with debug information enabled, the synthetic method will have a line debug attribute pointing to the source code line(s) holding the lambda expression, therefore you have a chance of finding the source of a particular Function
instance while debugging. In contrast, when encountering the instance returned by Function.identity()
during debugging an operation, you won’t know who has called that method and passed the instance to the operation.

The native JSON object includes two key methods.
1. JSON.parse()
2. JSON.stringify()
The JSON.parse()
method parses a JSON string - i.e. reconstructing the original JavaScript object
var jsObject = JSON.parse(jsonString);
JSON.stringify() method accepts a JavaScript object and returns its JSON equivalent.
var jsonString = JSON.stringify(jsObject);
What is the length of str array, and with how much 0s it is ending?
int main() {
char str[] = "Hello\0";
int length = sizeof str / sizeof str[0];
// "sizeof array" is the bytes for the whole array (must use a real array, not
// a pointer), divide by "sizeof array[0]" (sometimes sizeof *array is used)
// to get the number of items in the array
printf("array length: %d\n", length);
printf("last 3 bytes: %02x %02x %02x\n",
str[length - 3], str[length - 2], str[length - 1]);
return 0;
}

You were mixing up two different worlds.
Use a Comparator
like this:
List<Fruit> fruits= new ArrayList<Fruit>();
Fruit fruit;
for(int i = 0; i < 100; i++)
{
fruit = new Fruit();
fruit.setname(...);
fruits.add(fruit);
}
// Sorting
Collections.sort(fruits, new Comparator<Fruit>() {
@Override
public int compare(Fruit fruit2, Fruit fruit1)
{
return fruit1.fruitName.compareTo(fruit2.fruitName);
}
});
Now your fruits list is sorted based on fruitName
.
Starting from AngularJS 1.3 there's a new method called $watchGroup
for observing a set of expressions.
$scope.foo = 'foo';
$scope.bar = 'bar';
$scope.$watchGroup(['foo', 'bar'], function(newValues, oldValues, scope) {
// newValues array contains the current values of the watch expressions
// with the indexes matching those of the watchExpression array
// i.e.
// newValues[0] -> $scope.foo
// and
// newValues[1] -> $scope.bar
});
A good solution for me was to drop the rows with any null values:
Dataset<Row> filtered = df.filter(row => !row.anyNull);
In case one is interested in the other case, just call row.anyNull
.

There are several ways to go about this, it depends what your purpose is, if you just want to execute the function as well and in the same context, you can use .apply()
:
function init(){
doSomething();
}
function myFunc(){
init.apply(this, arguments);
doSomethingHereToo();
}
If you want to replace it with a newer init
, it'd look like this:
function init(){
doSomething();
}
//anytime later
var old_init = init;
init = function() {
old_init.apply(this, arguments);
doSomethingHereToo();
};
The accurate way is to use the __FUNCTION__
predefined magic constant.
Example:
class Test {
function MethodA(){
echo __FUNCTION__;
}
}
Result: MethodA
.
There are probably embedded tabs (CHAR(9)
) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:
DECLARE @var NVARCHAR(255), @i INT;
SET @i = 1;
SELECT @var = AccountType FROM dbo.Account
WHERE AccountNumber = 200
AND AccountType LIKE '%Daily%';
CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));
WHILE @i <= LEN(@var)
BEGIN
INSERT #x
SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));
SET @i = @i + 1;
END
SELECT i,c,a FROM #x ORDER BY i;
You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.
SELECT * FROM news WHERE date < DATEADD(Day, -1, date)
I would recommend using jQuery with this function:
$(document).ready(function(){
$('#about').addClass('expand');
});
This will add the expand class to an element with id of about when the dom is ready on page load.
Use a CSS media query @media
together with the CSS viewport units vw
and vh
to adapt to the aspect ratio of the viewport. This has the benefit of updating other properties, like font-size
, too.
This fiddle demonstrates the fixed aspect ratio for the div, and the text matching its scale exactly.
Initial size is based on full width:
div {
width: 100vw;
height: calc(100vw * 9 / 16);
font-size: 10vw;
/* align center */
margin: auto;
position: absolute;
top: 0px; right: 0px; bottom: 0px; left: 0px;
/* visual indicators */
background:
url(data:image/gif;base64,R0lGODlhAgAUAIABAB1ziv///yH5BAEAAAEALAAAAAACABQAAAIHhI+pa+EPCwA7) repeat-y center top,
url(data:image/gif;base64,R0lGODlhFAACAIABAIodZP///yH5BAEAAAEALAAAAAAUAAIAAAIIhI8Zu+nIVgEAOw==) repeat-x left center,
silver;
}
Then, when the viewport is wider than the desired aspect ratio, switch to height as base measure:
/* 100 * 16/9 = 177.778 */
@media (min-width: 177.778vh) {
div {
height: 100vh;
width: calc(100vh * 16 / 9);
font-size: calc(10vh * 16 / 9);
}
}
This is very similar in vein to the max-width
and max-height
approach by @Danield, just more flexible.
How about this?
=IF(ISERROR(MATCH(A1,B:B, 0)), "No Match", INDIRECT(ADDRESS(MATCH(A1,B:B, 0), 3)))
The "3" at the end means for column C.
Another approach that's a little more semantic is to have a UL defined as your total 6 image width, each LI defined as float left and width defined - so that when LI #7 hits, it runs into the boundry of the UL, and is pushed down to the new row. You'll still have an open float that you'll want to clear after the /UL - but that can be done on the next element of the page, or as a clear div. Here's sort of the idea, you may have to mess with actual values, but this should give you the idea. The code is a little cleaner.
<style type="text/css">
ul#imageSet { width: 600px; margin: 0; padding:0; }
ul#imageSet li { float: left; width: 100px; height: 188px; margin: 0; padding:0; position: relative; list-style-type: none; }
.cornerimage { position: absolute; bottom: 0; right: 0; }
h3.nextelement { clear: both; }
</style>
