Check whether you are actually under a github repo.
So, listing of .git/ should give you results..otherwise you may be some level outside your repo.
Now, cd to your repo and you are good to go.
Button btn = new Button(this);
btn.setText("Submit");

In my case I'm calling an API hosted by AWS (API Gateway). The error happened when I tried to call the API from a domain other than the API own domain. Since I'm the API owner I enabled CORS for the test environment, as described in the Amazon Documentation.
In production this error will not happen, since the request and the api will be in the same domain.
I hope it helps!
If you want to render HTML file you can use sendFile()
method without using any template engine
const express = require("express")
const path = require("path")
const app = express()
app.get("/",(req,res)=>{
res.sendFile(**path.join(__dirname, 'htmlfiles\\index.html')**)
})
app.listen(8000,()=>{
console.log("server is running at Port 8000");
})
I have an HTML file inside htmlfile so I used path module to render index.html path is default module in node. if your file is present in root folder just used
res.sendFile(path.join(__dirname, 'htmlfiles\\index.html'))
inside app.get()
it will work
There is a whole page in the MATLAB documentation dedicated to this topic: Array vs. Matrix Operations. The gist of it is below:
MATLAB® has two different types of arithmetic operations: array operations and matrix operations. You can use these arithmetic operations to perform numeric computations, for example, adding two numbers, raising the elements of an array to a given power, or multiplying two matrices.
Matrix operations follow the rules of linear algebra. By contrast, array operations execute element by element operations and support multidimensional arrays. The period character (
.
) distinguishes the array operations from the matrix operations. However, since the matrix and array operations are the same for addition and subtraction, the character pairs.+
and.-
are unnecessary.
Yes, I found MySQL also cannot edit result tables. Usually results tables joining other tables don't have primary keys. I heard other suggested put the result table in another table, but the better solution is to use Dbeaver which can edit result tables.
>>> x = "a (b) c (d) e"
>>> re.search(r"\(.*\)", x).group()
'(b) c (d)'
>>> re.search(r"\(.*?\)", x).group()
'(b)'
The '
*
', '+
', and '?
' qualifiers are all greedy; they match as much text as possible. Sometimes this behavior isn’t desired; if the RE<.*>
is matched against '<H1>title</H1>
', it will match the entire string, and not just '<H1>
'. Adding '?
' after the qualifier makes it perform the match in non-greedy or minimal fashion; as few characters as possible will be matched. Using.*?
in the previous expression will match only '<H1>
'.
The easiest way for me without having to reinvent the wheel.
void Clear()
{
#if defined _WIN32

del
statement does not delete an instance, it merely deletes a name.When you do del i
, you are deleting just the name i - but the instance is still bound to some other name, so it won't be Garbage-Collected.
If you want to release memory, your dataframes has to be Garbage-Collected, i.e. delete all references to them.
If you created your dateframes dynamically to list, then removing that list will trigger Garbage Collection.
>>> lst = [pd.DataFrame(), pd.DataFrame(), pd.DataFrame()]
>>> del lst # memory is released
>>> a, b, c = pd.DataFrame(), pd.DataFrame(), pd.DataFrame()
>>> lst = [a, b, c]
>>> del a, b, c # dfs still in list
>>> del lst # memory release now
To see if a dataframe is empty, I argue that one should test for the length of a dataframe's columns index:
if len(df.columns) == 0: 1
According to the Pandas Reference API, there is a distinction between:
NaN
hence at least 1 columnArguably, they are not the same. The other answers are imprecise in that df.empty
, len(df)
, or len(df.index)
make no distinction and return index is 0 and empty is True in both cases.
Example 1: An empty dataframe with 0 rows and 0 columns
In [1]: import pandas as pd
df1 = pd.DataFrame()
df1
Out[1]: Empty DataFrame
Columns: []
Index: []
In [2]: len(df1.index) # or len(df1)
Out[2]: 0
In [3]: df1.empty
Out[3]: True
Example 2: A dataframe which is emptied to 0 rows but still retains n
columns
In [4]: df2 = pd.DataFrame({'AA' : [1, 2, 3], 'BB' : [11, 22, 33]})
df2
Out[4]: AA BB
0 1 11
1 2 22
2 3 33
In [5]: df2 = df2[df2['AA'] == 5]
df2
Out[5]: Empty DataFrame
Columns: [AA, BB]
Index: []
In [6]: len(df2.index) # or len(df2)
Out[6]: 0
In [7]: df2.empty
Out[7]: True
Now, building on the previous examples, in which the index is 0 and empty is True. When reading the length of the columns index for the first loaded dataframe df1, it returns 0 columns to prove that it is indeed empty.
In [8]: len(df1.columns)
Out[8]: 0
In [9]: len(df2.columns)
Out[9]: 2
Critically, while the second dataframe df2 contains no data, it is not completely empty because it returns the amount of empty columns that persist.
Let's add a new column to these dataframes to understand the implications:
# As expected, the empty column displays 1 series
In [10]: df1['CC'] = [111, 222, 333]
df1
Out[10]: CC
0 111
1 222
2 333
In [11]: len(df1.columns)
Out[11]: 1
# Note the persisting series with rows containing `NaN` values in df2
In [12]: df2['CC'] = [111, 222, 333]
df2
Out[12]: AA BB CC
0 NaN NaN 111
1 NaN NaN 222
2 NaN NaN 333
In [13]: len(df2.columns)
Out[13]: 3
It is evident that the original columns in df2 have re-surfaced. Therefore, it is prudent to instead read the length of the columns index with len(pandas.core.frame.DataFrame.columns)
to see if a dataframe is empty.
# New dataframe df
In [1]: df = pd.DataFrame({'AA' : [1, 2, 3], 'BB' : [11, 22, 33]})
df
Out[1]: AA BB
0 1 11
1 2 22
2 3 33
# This data manipulation approach results in an empty df
# because of a subset of values that are not available (`NaN`)
In [2]: df = df[df['AA'] == 5]
df
Out[2]: Empty DataFrame
Columns: [AA, BB]
Index: []
# NOTE: the df is empty, BUT the columns are persistent
In [3]: len(df.columns)
Out[3]: 2
# And accordingly, the other answers on this page
In [4]: len(df.index) # or len(df)
Out[4]: 0
In [5]: df.empty
Out[5]: True
# SOLUTION: conditionally check for empty columns
In [6]: if len(df.columns) != 0: # <--- here
# Do something, e.g.
# drop any columns containing rows with `NaN`
# to make the df really empty
df = df.dropna(how='all', axis=1)
df
Out[6]: Empty DataFrame
Columns: []
Index: []
# Testing shows it is indeed empty now
In [7]: len(df.columns)
Out[7]: 0
Adding a new data series works as expected without the re-surfacing of empty columns (factually, without any series that were containing rows with only NaN
):
In [8]: df['CC'] = [111, 222, 333]
df
Out[8]: CC
0 111
1 222
2 333
In [9]: len(df.columns)
Out[9]: 1

If you want to delete lines 5 through 10 and 12:
sed -e '5,10d;12d' file
This will print the results to the screen. If you want to save the results to the same file:
sed -i.bak -e '5,10d;12d' file
This will back the file up to file.bak
, and delete the given lines.
Note: Line numbers start at 1. The first line of the file is 1, not 0.
I would prefer to not use ts-node and always run from dist folder.
To do that, just setup your package.json with default config:
....
"main": "dist/server.js",
"scripts": {
"build": "tsc",
"prestart": "npm run build",
"start": "node .",
"dev": "nodemon"
},
....
and then add nodemon.json config file:
{
"watch": ["src"],
"ext": "ts",
"ignore": ["src/**/*.spec.ts"],
"exec": "npm restart"
}
Here, i use "exec": "npm restart"
so all ts file will re-compile to js file and then restart the server.
To run while in dev environment,
npm run dev
Using this setup I will always run from the distributed files and no need for ts-node.
find supports wildcard matches, just add a *
:
find / -type d -name "ora10*"
One thing I've learnt the hard way is being consistent
Watch out for mixing:
import { BehaviorSubject } from "rxjs";
with
import { BehaviorSubject } from "rxjs/BehaviorSubject";
This will probably work just fine UNTIL you try to pass the object to another class (where you did it the other way) and then this can fail
(myBehaviorSubject instanceof Observable)
It fails because the prototype chain will be different and it will be false.
I can't pretend to understand exactly what is happening but sometimes I run into this and need to change to the longer format.
When you aren't doing anything to make your class particularly designed to work with a given framework, ORM, or other system that needs a special sort of class, you have a Plain Old Java Object, or POJO.
Ironically, one of the reasons for coining the term is that people were avoiding them in cases where they were sensible and some people concluded that this was because they didn't have a fancy name. Ironic, because your question demonstrates that the approach worked.
Compare the older POD "Plain Old Data" to mean a C++ class that doesn't do anything a C struct couldn't do (more or less, non-virtual members that aren't destructors or trivial constructors don't stop it being considered POD), and the newer (and more directly comparable) POCO "Plain Old CLR Object" in .NET.
With JTable.AUTO_RESIZE_OFF
, the table will not change the size of any of the columns for you, so it will take your preferred setting. If it is your goal to have the columns default to your preferred size, except to have the last column fill the rest of the pane, You have the option of using the JTable.AUTO_RESIZE_LAST_COLUMN
autoResizeMode, but it might be most effective when used with TableColumn.setMaxWidth()
instead of TableColumn.setPreferredWidth() for all but the last column.
Once you are satisfied that AUTO_RESIZE_LAST_COLUMN
does in fact work, you can experiment with a combination of TableColumn.setMaxWidth()
and TableColumn.setMinWidth()

Here's a situation where you HAVE to use property accessors. Imagine you have a GENERIC abstract class with lots of implementation goodness to inherit into 8 concrete subclasses:
public abstract class Foo<T extends Bar> {
T oneThing;
T anotherThing;
// getters and setters ommited for brevity
// Lots and lots of implementation regarding oneThing and anotherThing here
}
Now exactly how should you annotate this class? The answer is YOU CAN'T annotate it at all with either field or property access because you can't specify the target entity at this point. You HAVE to annotate the concrete implementations. But since the persisted properties are declared in this superclass, you MUST used property access in the subclasses.
Field access is not an option in an application with abstract generic super-classes.
The exact answer to the question is: yes, you can use an arbitrary value for the boundary
parameter, given it does not exceed 70 bytes in length and consists only of 7-bit US-ASCII
(printable) characters.
If you are using one of multipart/*
content types, you are actually required to specify the boundary
parameter in the Content-Type
header, otherwise the server (in the case of an HTTP request) will not be able to parse the payload.
You probably also want to set the charset
parameter to UTF-8
in your Content-Type
header, unless you can be absolutely sure that only US-ASCII
charset will be used in the payload data.
A few relevant excerpts from the RFC2046:
4.1.2. Charset Parameter:
Unlike some other parameter values, the values of the charset parameter are NOT case sensitive. The default character set, which must be assumed in the absence of a charset parameter, is US-ASCII.
5.1. Multipart Media Type
As stated in the definition of the Content-Transfer-Encoding field [RFC 2045], no encoding other than "7bit", "8bit", or "binary" is permitted for entities of type "multipart". The "multipart" boundary delimiters and header fields are always represented as 7bit US-ASCII in any case (though the header fields may encode non-US-ASCII header text as per RFC 2047) and data within the body parts can be encoded on a part-by-part basis, with Content-Transfer-Encoding fields for each appropriate body part.
The Content-Type field for multipart entities requires one parameter, "boundary". The boundary delimiter line is then defined as a line consisting entirely of two hyphen characters ("-", decimal value 45) followed by the boundary parameter value from the Content-Type header field, optional linear whitespace, and a terminating CRLF.
Boundary delimiters must not appear within the encapsulated material, and must be no longer than 70 characters, not counting the two leading hyphens.
The boundary delimiter line following the last body part is a distinguished delimiter that indicates that no further body parts will follow. Such a delimiter line is identical to the previous delimiter lines, with the addition of two more hyphens after the boundary parameter value.
Here is an example using an arbitrary boundary:
Content-Type: multipart/form-data; charset=utf-8; boundary="another cool boundary"
--another cool boundary
Content-Disposition: form-data; name="foo"
bar
--another cool boundary
Content-Disposition: form-data; name="baz"
quux
--another cool boundary--
Make sure the required dlls are exported (or copied manually) to the bin folder when building your application.

You can use a separate config file per configuration, e.g. app.Debug.config, app.Release.config and then use the configuration variable in your project file:
<PropertyGroup>
<AppConfig>App.$(Configuration).config</AppConfig>
</PropertyGroup>
This will then create the correct ProjectName.exe.config file depending on the configuration you are building in.
You can use the following regex to replace non-ASCII characters
str = str.replace(/[^A-Za-z 0-9 \.,\?""!@#\$%\^&\*\(\)-_=\+;:<>\/\\\|\}\{\[\]`~]*/g, '')
However, note that spaces, colons and commas are all valid ASCII, so the result will be
> str
"INFO] :, , , (Higashikurume)"
First you have to ensure that there is a SMTP server listening on port 25.
To look whether you have the service, you can try using TELNET client, such as:
C:\> telnet localhost 25
(telnet client by default is disabled on most recent versions of Windows, you have to add/enable the Windows component from Control Panel. In Linux/UNIX usually telnet client is there by default.
$ telnet localhost 25
If it waits for long then time out, that means you don't have the required SMTP service. If successfully connected you enter something and able to type something, the service is there.
If you don't have the service, you can use these:
If you are sure that you already have the service, may be the SMTP requires additional security credentials. If you can tell me what SMTP server listening on port 25 I may be able to tell you more.
Kevin Pope's comment under the accepted answer was what I needed.
The problem, in my case, was that I had triggers defined on my table that would insert update/insert transactions into an audit table, but the audit table had a data type mismatch where a column with VARCHAR(MAX)
in the original table was stored as VARCHAR(1)
in the audit table, so my triggers were failing when I would insert anything greater than VARCHAR(1)
in the original table column and I would get this error message.
This will help you.

SOAP currently has the advantage of better tools where they will generate a lot of the boilerplate code for both the service layer as well as generating clients from any given WSDL.
REST is simpler, can be easier to maintain as a result, lies at the heart of Web architecture, allows for better protocol visibility, and has been proven to scale at the size of the WWW itself. Some frameworks out there help you build REST services, like Ruby on Rails, and some even help you with writing clients, like ADO.NET Data Services. But for the most part, tool support is lacking.
To answer my own question, the trick is to turn auto scaling off...
p.axis([0.0,600.0, 10000.0,20000.0])
ax = p.gca()
ax.set_autoscale_on(False)
In order to do this in SQL Server, you must order the query by a column, so you can specify the rows you want.
You can't use the "TOP" keyword when doing this, you must use offset N rows fetch next M rows.
Example:
select * from table order by [some_column]
offset 10 rows
FETCH NEXT 10 rows only

You said programmatically, right? I hope C# is ok. I know you said that you tried SMO and it didn't quite do what you wanted, so this probably won't be perfect for your request, but it will programmatically read out legit SQL statements that you could run to recreate the stored procedure. If it doesn't have the GO
statements that you want, you can probably assume that each of the strings in the StringCollection
could have a GO
after it. You may not get that comment with the date and time in it, but in my similar sounding project (big-ass deployment tool that has to back up everything individually), this has done rather nicely. If you have a prior base that you wanted to work from, and you still have the original database to run this on, I'd consider tossing the initial effort and restandardizing on this output.

If you are trying to use AngularJs 1.6.6 as of 21/10/2017 the following parameter works as .success and has been depleted. The .then() method takes two arguments: a response and an error callback which will be called with a response object.
$scope.login = function () {
$scope.btntext = "Please wait...!";
$http({
method: "POST",
url: '/Home/userlogin', // link UserLogin with HomeController
data: $scope.user
}).then(function (response) {
console.log("Result value is : " + parseInt(response));
data = response.data;
$scope.btntext = 'Login';
if (data == 1) {
window.location.href = '/Home/dashboard';
}
else {
alert(data);
}
}, function (error) {
alert("Failed Login");
});
The above snipit works for a login page.
If you are converting string to float:
import re
A1 = [' "29.0" ',' "65.2" ',' "75.2" ']
float_values = [float(re.search(r'\d+.\d+',number).group()) for number in A1]
print(float_values)
>>> [29.0, 65.2, 75.2]
At terminal run this command with root permission:
sudo /etc/init.d/apache2 start
You must be root for starting a webserver otherwise you would get similar error.
This worked for me, no need to keep a lastSelected
if you know the optionIndex
to select.
var optionIndex = ...
$(this)[0].options[optionIndex].selected = true;
The web site likely uses cookies to store your session information. When you run
curl --user user:pass https://xyz.com/a #works ok
curl https://xyz.com/b #doesn't work
curl
is run twice, in two separate sessions. Thus when the second command runs, the cookies set by the 1st command are not available; it's just as if you logged in to page a
in one browser session, and tried to access page b
in a different one.
What you need to do is save the cookies created by the first command:
curl --user user:pass --cookie-jar ./somefile https://xyz.com/a
and then read them back in when running the second:
curl --cookie ./somefile https://xyz.com/b
Alternatively you can try downloading both files in the same command, which I think will use the same cookies.
Another thing to watch out for is double backslashes, since xcopy
does not tolerate them in the input path parameter (but it does tolerate them in the output path...).
Is there any other way to convert that array into string ?
You don't want to convert the array to a string, you want to get the value of the array's sole element, if I read it correctly.
<?php
$foo = array( 18 => 'Something' );
$value = array_shift( $foo );
echo $value; // 'Something'.
?>
Using array_shift you don't have to worry about the index.
EDIT: Mind you, array_shift is not the only function that will return a single value. array_pop( ), current( ), end( ), reset( ), they will all return that one single element. All of the posted solutions work. Using array shift though, you can be sure that you'll only ever get the first value of the array, even when there are multiple.
For nginx users
Use the following in your conf file for your site (usually /etc/nginx/sites-available/example.com
)
location / {
try_files $uri $uri/ /index.php?q=$uri&$args;
}
This hands off all permalink requests to index.php with a URI string and supplied arguments. Do a systemctl reload nginx
to see the changes and your non-homepage links should load.
I face the similar issue and surprisingly meta tag didn't work this time. Turns out the company I currently cooperate with has this enterprise mode setting which has priority over meta tag.
We can't change the setting cause policy issue. Luckily I don't really need any fancy features but basic usage of jQuery so my final solution is to switch its version to 1.12 for better compatibility.
for me the solution was to include skip = 0 (number of rows to skip at the top of the file. Can be set >0)
mydata <- read.csv(file = "file.csv", header = TRUE, sep = ",", skip = 22)
I had this issue because I was using Charles proxy on my computer and the SSL was enabled for all hosts. And since AS didn't trust my proxy, the network request failed. So I had to disable SSL for all hosts and restart my Android Studio.
The (currently) top-ranked answer (with the ActiveState code) is overly complicated. I don't see a reason to use classes when a mere function should suffice. Below are two implementations that accomplish the same thing but with more readable code.
Both of these implementations:
Version 1: readable and simple
def getChar():
try:
# for Windows-based systems
import msvcrt # If successful, we are on Windows
return msvcrt.getch()
except ImportError:
# for POSIX-based systems (with termios & tty support)
import tty, sys, termios # raises ImportError if unsupported
fd = sys.stdin.fileno()
oldSettings = termios.tcgetattr(fd)
try:
tty.setcbreak(fd)
answer = sys.stdin.read(1)
finally:
termios.tcsetattr(fd, termios.TCSADRAIN, oldSettings)
return answer
Version 2: avoid repeated imports and exception handling:
[EDIT] I missed one advantage of the ActiveState code. If you plan to read characters multiple times, that code avoids the (negligible) cost of repeating the Windows import and the ImportError exception handling on Unix-like systems. While you probably should be more concerned about code readability than that negligible optimization, here is an alternative (it is similar to Louis's answer, but getChar() is self-contained) that functions the same as the ActiveState code and is more readable:
def getChar():
# figure out which function to use once, and store it in _func
if "_func" not in getChar.__dict__:
try:
# for Windows-based systems
import msvcrt # If successful, we are on Windows
getChar._func=msvcrt.getch
except ImportError:
# for POSIX-based systems (with termios & tty support)
import tty, sys, termios # raises ImportError if unsupported
def _ttyRead():
fd = sys.stdin.fileno()
oldSettings = termios.tcgetattr(fd)
try:
tty.setcbreak(fd)
answer = sys.stdin.read(1)
finally:
termios.tcsetattr(fd, termios.TCSADRAIN, oldSettings)
return answer
getChar._func=_ttyRead
return getChar._func()
Example code that exercises either of the getChar() versions above:
from __future__ import print_function # put at top of file if using Python 2
# Example of a prompt for one character of input
promptStr = "Please give me a character:"
responseStr = "Thank you for giving me a '{}'."
print(promptStr, end="\n> ")
answer = getChar()
print("\n")
print(responseStr.format(answer))

I also need this feature on Firebug! Until then, another approach is to use this online service to remove classes and convert the css to inline styles.

You may try the following if your database does not have any data OR you have another away to restore that data. You will need to know the Ubuntu server root password but not the mysql root password.
It is highly probably that many of us have installed "mysql_secure_installation" as this is a best practice. Navigate to bin directory where mysql_secure_installation exist. It can be found in the /bin directory on Ubuntu systems. By rerunning the installer, you will be prompted about whether to change root database password.
Try this
/.*[^a]$/
The []
denotes a character class, and the ^
inverts the character class to match everything but an a

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbarAlwaysDrawHorizontalTrack="true" />
You can set the System properties as VM arguments.
If your project is a maven project then you can execute following command while running the test class:
mvn test -Dapp.url="https://stackoverflow.com"
Test class:
public class AppTest {
@Test
public void testUrl() {
System.out.println(System.getProperty("app.url"));
}
}
If you want to run individual test class or method in eclipse then :
1) Go to Run -> Run Configuration
2) On left side select your Test class under the Junit section.
3) do the following :
A much faster implementation would be to use list-comprehension
if you need to rename a single column.
df.columns = ['log(gdp)' if x=='gdp' else x for x in df.columns]
If the need arises to rename multiple columns, either use conditional expressions like:
df.columns = ['log(gdp)' if x=='gdp' else 'cap_mod' if x=='cap' else x for x in df.columns]
Or, construct a mapping using a dictionary
and perform the list-comprehension
with it's get
operation by setting default value as the old name:
col_dict = {'gdp': 'log(gdp)', 'cap': 'cap_mod'} ## key?old name, value?new name
df.columns = [col_dict.get(x, x) for x in df.columns]
Timings:
%%timeit
df.rename(columns={'gdp':'log(gdp)'}, inplace=True)
10000 loops, best of 3: 168 µs per loop
%%timeit
df.columns = ['log(gdp)' if x=='gdp' else x for x in df.columns]
10000 loops, best of 3: 58.5 µs per loop
That's what ln
is documented to do when the target already exists and is a directory. If you want /etc/nginx
to be a symlink rather than contain a symlink, you had better not create it as a directory first!
You need to start your Apache Server normally you should have an xampp icon in the info-section from the taskbar, with this tool you can start the apache server as wel as the mysql database (if you need it)
Honestly, the best way to limit files is on the server side. People can spoof file type on the client so taking in the full file name at server transfer time, parsing out the file type, and then returning a message is usually the best bet.
I would really like to see your TABLE's styling. E.g. "border-collapse"
Just a guess, but it might affect how 'hidden' rows are being rendered.
you can use this bash script
and run
./convert.sh -f example/mycsvfile.csv
In case you do need to define dataSource()
, for example when you have multiple data sources, you can use:
@Autowired Environment env;
@Primary
@Bean
public DataSource customDataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getProperty("custom.datasource.driver-class-name"));
dataSource.setUrl(env.getProperty("custom.datasource.url"));
dataSource.setUsername(env.getProperty("custom.datasource.username"));
dataSource.setPassword(env.getProperty("custom.datasource.password"));
return dataSource;
}
By setting up the dataSource
yourself (instead of using DataSourceBuilder
), it fixed my problem which you also had.
The always knowledgeable Baeldung has a tutorial which explains in depth.
Below is a list of the common key codes for quick reference, taken from Events.h
.
If you need to use these keycodes in an application, you should include the Carbon framework:
Objective-C:
#include <Carbon/Carbon.h>
Swift:
import Carbon.HIToolbox
You can then use the kVK_ANSI_A
constants directly.
The key constants reference physical keys on the keyboard. Their output changes if the typist is using a different keyboard layout. The letters in the constants correspond only to the U.S. QWERTY keyboard layout.
For example, the left ring-finger key on the homerow:
QWERTY keyboard layout
> s > kVK_ANSI_S
> "s"
Dvorak keyboard layout
> o > kVK_ANSI_S
> "o"
Strategies for layout-agnostic conversion of keycode to string, and vice versa, are discussed here:
How to convert ASCII character to CGKeyCode?
From Events.h
:
/*
* Summary:
* Virtual keycodes
*
* Discussion:
* These constants are the virtual keycodes defined originally in
* Inside Mac Volume V, pg. V-191. They identify physical keys on a
* keyboard. Those constants with "ANSI" in the name are labeled
* according to the key position on an ANSI-standard US keyboard.
* For example, kVK_ANSI_A indicates the virtual keycode for the key
* with the letter 'A' in the US keyboard layout. Other keyboard
* layouts may have the 'A' key label on a different physical key;
* in this case, pressing 'A' will generate a different virtual
* keycode.

What I do is run sudo du -khd 1 in the Terminal to see my file system's storage amounts for each folder in simple text, then drill up/down into where the huge GB are hiding using the cd command.
Ultimately you'll find the Users//Library/Developer/CoreSimulator/Devices folder where you can have little concern about deleting all those "devices" using iOS versions you no longer need. It's also safe to just delete them all, but keep in mind you'll lose data that's written to the device like sqlite files you may want to use as a backup version.
I once saved over 50GB doing this since I did so much testing on older iOS versions.
You can actually still use ".css" and apply css transitions to the div being affected. So continue using ".css" and add the below styles to your stylesheet for "#hfont1". Since ".css" allows for a lot more properties than ".animate", this is always my preferred method.
#hfont1 {
-webkit-transition: width 0.4s;
transition: width 0.4s;
}
Needs to be:
if (document.forms[0].elements["checkAddress"].checked == true)
Assuming you have one form, otherwise use the form name.
As a side note, don't call the element and the function in the same name it can cause weird conflicts.
Just use like this somewhere inside the form
@method('PUT')

I had the same issue to connect an SQL_server 2008 to an SQL_server 2016 hosted in a remote server. @Domnic answer didn't worked for me straightforward. I write my tweaked solution here as I think it may be useful for someone else.
An extended answer for remote IP db connections:
Step 1: Link servers
EXEC sp_addlinkedserver @server='SRV_NAME',
@srvproduct=N'',
@provider=N'SQLNCLI',
@datasrc=N'aaa.bbb.ccc.ddd';
EXEC sp_addlinkedsrvlogin 'SRV_NAME', 'false', NULL, 'your_remote_db_login_user', 'your_remote_db_login_password'
...where SRV_NAME
is an invented name. We will use it to refer to the remote server from our queries. aaa.bbb.ccc.ddd
is the ip address of the remote server hosting your SQLserver DB.
Step 2: Run your queries For instance:
SELECT * FROM [SRV_NAME].your_remote_db_name.dbo.your_table
...and that's it!
Syntax details: sp_addlinkedserver and sp_addlinkedsrvlogin
This error is cause by security clutches between the web application and your java. To resolve it, look into your java setting under control panel. Move the security level to a medium.
You can do as @rmobis has specified in his answer, [Adding something more into it]
Using order by
twice:
MyTable::orderBy('coloumn1', 'DESC')
->orderBy('coloumn2', 'ASC')
->get();
and the second way to do it is,
Using raw order by
:
MyTable::orderByRaw("coloumn1 DESC, coloumn2 ASC");
->get();
Both will produce same query as follow,
SELECT * FROM `my_tables` ORDER BY `coloumn1` DESC, `coloumn2` ASC
As @rmobis specified in comment of first answer you can pass like an array to order by column like this,
$myTable->orders = array(
array('column' => 'coloumn1', 'direction' => 'desc'),
array('column' => 'coloumn2', 'direction' => 'asc')
);
one more way to do it is iterate
in loop,
$query = DB::table('my_tables');
foreach ($request->get('order_by_columns') as $column => $direction) {
$query->orderBy($column, $direction);
}
$results = $query->get();
Hope it helps :)
You could have probably concluded your question after the second paragraph, rather than calling people "insane" simply because they have a different viewpoint than you do and otherwise trying to mock professionals who may have a very good reason for feeling the way that they do.
As to your question, while there are certainly situations where a cursor may be called for, in my experience developers decide that a cursor "must" be used FAR more often than is actually the case. The chance of someone erring on the side of too much use of cursors vs. not using them when they should is MUCH higher in my opinion.
Adding to the answer of stackoverflowuser2010, in the general case you can just use
data = np.array([[1,1,1],[2,2,2],[3,3,3]])
vector = np.array([1,2,3])
data / vector.reshape(-1,1)
This will turn your vector into a column matrix/vector
. Allowing you to do the elementwise operations as you wish. At least to me, this is the most intuitive way going about it and since (in most cases) numpy will just use a view of the same internal memory for the reshaping it's efficient too.
Put the threads in a list and then use the Join method
threads = []
t = Thread(...)
threads.append(t)
...repeat as often as necessary...
# Start all threads
for x in threads:
x.start()
# Wait for all of them to finish
for x in threads:
x.join()
For the OP's command:
select compid,2, convert(datetime, '01/01/' + CONVERT(char(4),cal_yr) ,101) ,0, Update_dt, th1, th2, th3_pc , Update_id, Update_dt,1
from #tmp_CTF**
I get this error:
Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '*'.
when debugging something like this split the long line up so you'll get a better row number:
select compid
,2
, convert(datetime
, '01/01/'
+ CONVERT(char(4)
,cal_yr)
,101)
,0
, Update_dt
, th1
, th2
, th3_pc
, Update_id
, Update_dt
,1
from #tmp_CTF**
this now results in:
Msg 102, Level 15, State 1, Line 16
Incorrect syntax near '*'.
which is probably just from the OP not putting the entire command in the question, or use [ ] braces to signify the table name:
from [#tmp_CTF**]
if that is the table name.
Use in XML:
android:src="@drawable/image"
Source use:
imageView.setImageDrawable(ContextCompat.getDrawable(activity, R.drawable.your_image));
super()
lets you avoid referring to the base class explicitly, which can be nice. But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen. See the standard docs on super if you haven't already.
Note that the syntax changed in Python 3.0: you can just say super().__init__()
instead of super(ChildB, self).__init__()
which IMO is quite a bit nicer. The standard docs also refer to a guide to using super()
which is quite explanatory.
Would like to thank you for some excellent replies. @AR., your a star and it works perfectly. I had noticed last night that the Excel.exe

private String fileLoc = @"C:\temp\test.xls";
static void Main(string[] args)
{
Program p = new Program();
p.createExcel();
}
private void createExcel()
{
Excel.Application excelApp = null;
Excel.Workbook workbook = null;
Excel.Sheets sheets = null;
Excel.Worksheet newSheet = null;
try
{
FileInfo file = new FileInfo(fileLoc);
if (file.Exists)
{
excelApp = new Excel.Application();
workbook = excelApp.Workbooks.Open(fileLoc, 0, false, 5, "", "",
false, XlPlatform.xlWindows, "",
true, false, 0, true, false, false);
sheets = workbook.Sheets;
//check columns exist
foreach (Excel.Worksheet sheet in sheets)
{
Console.WriteLine(sheet.Name);
sheet.Select(Type.Missing);
System.Runtime.InteropServices.Marshal.ReleaseComObject(sheet);
}
newSheet = (Worksheet)sheets.Add(sheets[1], Type.Missing, Type.Missing, Type.Missing);
newSheet.Name = "My New Sheet";
newSheet.Cells[1, 1] = "BOO!";
workbook.Save();
workbook.Close(null, null, null);
excelApp.Quit();
}
}
finally
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(newSheet);
System.Runtime.InteropServices.Marshal.ReleaseComObject(sheets);
System.Runtime.InteropServices.Marshal.ReleaseComObject(workbook);
System.Runtime.InteropServices.Marshal.ReleaseComObject(excelApp);
newSheet = null;

Use PHP's $_POST
or $_GET
superglobals to retrieve the value of the input tag via the name of the HTML tag.
For Example, change the method in your form and then echo out the value by the name of the input:
Using $_GET
method:
<form name="form" action="" method="get">
<input type="text" name="subject" id="subject" value="Car Loan">
</form>
To show the value:
<?php echo $_GET['subject']; ?>
Using $_POST
method:
<form name="form" action="" method="post">
<input type="text" name="subject" id="subject" value="Car Loan">
</form>
To show the value:
<?php echo $_POST['subject']; ?>
With the new version of React Router (using 2.0.1 now), you can use an asterisk as a path to route all 'other paths'.
So it would look like this:
<Route route="/" component={App}>
<Route path=":area" component={Area}>
<Route path=":city" component={City} />
<Route path=":more-stuff" component={MoreStuff} />
</Route>
<Route path="*" component={NotFoundRoute} />
</Route>
In addition to the example given in the Advanced Bash Scripting Guide referenced by Jefromi, these examples show how pipes create subshells:
$ echo $$ $BASHPID | cat -
11656 31528
$ echo $$ $BASHPID
11656 11656
$ echo $$ | while read line; do echo $line $$ $BASHPID; done
11656 11656 31497
$ while read line; do echo $line $$ $BASHPID; done <<< $$
11656 11656 11656
I don't think this question has been completely answered yet because all of the answers only give single match examples. The OP's question demonstrates the nuances of having 2 matches as well as a substring match which should not be reported because it is not a word/token.
To match multiple occurrences, one might do something like this:
iter = re.finditer(r"\bis\b", String)
indices = [m.start(0) for m in iter]
This would return a list of the two indices for the original string.
If you are using Kotlin then this will solve your problem. (MS Json format)
val dataString = "/Date(1586583441106)/"
val date = Date(Long.parseLong(dataString.substring(6, dataString.length - 2)))
Actually issues in one of Ubuntu machine is ssh-keygen command was not run properly. I tried running again and navigated into /home/user1/.ssh and able to see id_rsa and id_rsa.pub keys. then tried command ssh-copy-id and it was working fine.
The code says everything:
max@serv$ chmod 777 .
Okay, it doesn't say everything.
In UNIX and Linux, the ability to remove a file is not determined by the access bits of that file. It is determined by the access bits of the directory which contains the file.
Think of it this way -- deleting a file doesn't modify that file. You aren't writing to the file, so why should "w" on the file matter? Deleting a file requires editing the directory that points to the file, so you need "w" on the that directory.
I had the same problem when I was using Eclipse Juno.. I installed Eclipse Indigo and it works fine. Try to reinstall eclipse.
Another variation you can try is(expanding @mnel's answer) if you have many temp'x'.
here "n" could be the number of temp variables present
rm(list = c(paste("temp",c(1:n),sep="")))
In my situation the 'NUnit3 Test Adapter' has been disabled. To re-enable it go to menu
Tools->Extensions and Updates...
On the left side select 'Installed'->'All'.
On the upper right corner search for 'nunit'.
If you have 'NUnit3 Test Adapter' installed, with the found item you can enable/disable it.
We can set the response headers in Python Flask application using Flask application context using flask.g
This way of setting response headers in Flask application context using flask.g
is thread safe and can be used to set custom & dynamic attributes from any file of application, this is especially helpful if we are setting custom/dynamic response headers from any helper class, that can also be accessed from any other file ( say like middleware, etc), this flask.g
is global & valid for that request thread only.
Say if i want to read the response header from another api/http call that is being called from this app, and then extract any & set it as response headers for this app.
Sample Code: file: helper.py
import flask
from flask import request, g
from multidict import CIMultiDict
from asyncio import TimeoutError as HttpTimeout
from aiohttp import ClientSession
def _extract_response_header(response)
"""

$("#data").multiSelect('deselect_all');
$("#data").multiSelect("select",data);
if (((Double)calcYourDouble()).toString().contains("-"))

$('#new_user_form :input')
should be your way forward. Note the omission of the >
selector. A valid HTML form wouldn't allow for a input tag being a direct child of a form tag.
I had the following entries in my /etc/hosts file:

Just by commenting them out, I fixed the problem.
Use json
. the ast
library consumes a lot of memory and and slower. I have a process that needs to read a text file of 156Mb. Ast
with 5 minutes delay for the conversion dictionary json
and 1 minutes using 60% less memory!
How about a shorthand notation?
{overflow: auto hidden;}
you can use
the character equivalent to 0x63 is 'c' but byte equivalent to it is 99
System.out.println("byte "+(char)0x63);
With nginx you can send both tokens like this (even though it's against the standard):
Authorization: Basic basic-token,Bearer bearer-token
This works as long as the basic token is first - nginx successfully forwards it to the application server.
And then you need to make sure your application can properly extract the Bearer from the above string.
Try this instead:
var body = $("body, html");
var top = body.scrollTop() // Get position of the body
if(top!=0)
{
body.animate({scrollTop :0}, 500,function(){
//DO SOMETHING AFTER SCROLL ANIMATION COMPLETED
alert('Hello');
});
}
You have a couple of options:
Remove the out-of-the-box ROOT/
directory from tomcat and rename your war file to ROOT.war
before deploying it.
Deploy your war as (from your example) war_name.war
and configure the context root in conf/server.xml
to use your war file :
<Context path="" docBase="war_name" debug="0" reloadable="true"></Context>
The first one is easier, but a little more kludgy. The second one is probably the more elegant way to do it.
This is the jQuery method. Looks like overkill but it calculates the offset.

The best solution I have found is:

self.close();
Can you post your code? I'm not finding any issue with this. Tested on Firefox 3.01/safari 3.1.2 with:

"saving" is something wholly different from changing paragraph content with jquery.
If you need to save changes you will have to write them to your server somehow (likely form submission along with all the security and input sanitizing that entails). If you have information that is saved on the server then you are no longer changing the content of a paragraph, you are drawing a paragraph with dynamic content (either from a database or a file which your server altered when you did the "saving").
Judging by your question, this is a topic on which you will have to do MUCH more research.
Input page (input.html):
<form action="/saveMyParagraph.php">
<input name="pContent" type="text"></input>
</form>
Saving page (saveMyParagraph.php) and Ouput page (output.php):
Use grep and regular expressions, for example if you want 4 minutes interval of logs:
grep "31/Mar/2002:19:3[1-5]" logfile
will return all logs lines between 19:31 and 19:35 on 31/Mar/2002. Supposing you need the last 5 days starting from today 27/Sep/2011 you may use the following:
grep "2[3-7]/Sep/2011" logfile
"Chrome violations" don't represent errors in either Chrome or your own web app. They are instead warnings to help you improve your app. In this case, Long running JavaScript
and took 83ms of runtime
are alerting you there's probably an opportunity to speed up your script.
("Violation" is not the best terminology; it's used here to imply the script "violates" a pre-defined guideline, but "warning" or similar would be clearer. These messages first appeared in Chrome in early 2017 and should ideally have a "More info" prompt to elaborate on the meaning and give suggested actions to the developer. Hopefully those will be added in the future.)
In VBA we can not use if jj = 5 or 6 then
we must use if jj = 5 or jj = 6 then
maybe this:
If inputWks.Range("d9") > 0 And (inputWks.Range("d11") = "Restricted_Expenditure" Or inputWks.Range("d11") = "Unrestricted_Expenditure") Then
One which preservers ordering that's simple to understand:
function rename_array_key(array $array, $old_key, $new_key) {
if (!array_key_exists($old_key, $array)) {
return $array;
}
$new_array = [];
foreach ($array as $key => $value) {
$new_key = $old_key === $key
? $new_key
: $key;
$new_array[$new_key] = $value;

return $new_array;

So I can see that we have right answers for different questions here; for a prime number generator gen_primes
looks like the right answer; but for a prime number check, the simple_is_prime
function is better suited.
This works, but I am always open to better ways to make is_prime
function.
If the content is not too large, you can also use
SELECT CAST ( <blobfield> AS RAW( <maxFieldLength> ) ) FROM <table>;
or
SELECT DUMP ( CAST ( <blobfield> AS RAW( <maxFieldLength> ) ) ) FROM <table>;
This will show you the HEX values.

Just my two cents for future visitors who have this problem.
This is the correct syntax for PHP 5.3, for example if you call static method from the class name:
MyClassName::getConfig($key);
If you previously assign the ClassName to the $cnf variable, you can call the static method from it (we are talking about PHP 5.3):
$cnf = MyClassName;
$cnf::getConfig($key);
However, this sintax doesn't work on PHP 5.2 or lower, and you need to use the following:
$cnf = MyClassName;
call_user_func(array($cnf, "getConfig", $key, ...otherposibleadditionalparameters... ));
Hope this helps people having this error in 5.2 version (don't know if this was openfrog's version).
You could do something like this also:
ol {
font-weight: bold;
}
ol > li > * {
font-weight: normal;
}
So you have no "style" attributes in your HTML
Bundler is a Gem manager which provides a consistent environment for Ruby projects by tracking and installing the exact gems and versions that are needed.
Gemfile and Gemfile.lock are primary products given by Bundler gem (Bundler itself is a gem).
Gemfile contains your project dependency on gem(s), that you manually mention with version(s) specified, but those gem(s) inturn depends on other gem(s) which is resolved by bundler automatically.
Gemfile.lock contain complete snapshot of all the gem(s) in Gemfile along with there associated dependency.
When you first call bundle install, it will create this Gemfile.lock and uses this file in all subsequent calls to bundle install, which ensures that you have all the dependencies installed and will skip dependency installation.
Same happens when you share your code with different machines
You share your Gemfile.lock along with Gemfile, when you run bundle install on other machine it will refer to your Gemfile.lock and skip dependency resolution step, instead it will install all of the same dependent gem(s) that you used on the original machine, which maintains consistency across multiple machines
Why do we need to maintain consistency along multiple machines ?
Running different versions on different machines could lead to broken code
Suppose, your app used the version 1.5.3 and it works 14 months ago
without any problems, and you try to install on different machine
without Gemfile.lock now you get the version 1.5.8. Maybe it's broken
with the latest version of some gem(s) and your application will
fail. Maintaining consistency is of utmost importance (preferred
practice).
It is also possible to update gem(s) in Gemfile.lock by using bundle update.
This is based on the concept of conservative updating
OK, after 2 years it's finally time to correct the syntax:
SELECT t1.value, t2.value
FROM MyTable t1
JOIN MyTable t2
ON t1.id = t2.id
WHERE t1.id = @id
AND t1.status = @status1
AND t2.status = @status2
No, it is not okay to put a link
element in the body tag. See the specification (links to the HTML4.01 specs, but I believe it is true for all versions of HTML):
“This element defines a link. Unlike

, it may only appear in theHEAD
section of a document, although it may appear any number of times.”
I had problems with collations as I had most of the tables with Modern_Spanish_CI_AS
, but a few, which I had inherited or copied from another Database, had SQL_Latin1_General_CP1_CI_AS
collation.
In my case, the easiest way to solve the problem has been as follows:
I hope this helps other users.
You need something like this:
foreach(DataColumn c in dr.Table.Columns)
{
MessageBox.Show(c.ColumnName);
}
I solved this by referring properties of login user under the security, logins. then go to User Mapping and select the database then check db_datareader and db_dataweriter options.
For the sake of completeness: the previous answers tell how to set the upstream branch, but not how to see it.
There are a few ways to do this:
git branch -vv
shows that info for all branches. (formatted in blue in most terminals)
cat .git/config
shows this also.

The response from server is JSON String format. If the set dataType as 'json' jquery will attempt to use it directly. You need to set dataType as 'text' and then parse it manually.
$.ajax({
type: 'GET',
dataType: "text", // You need to use dataType text else it will try to parse it.
url: "http://someotherdomain.com/service.svc",
success: function (responseData, textStatus, jqXHR) {
console.log("in");
var data = JSON.parse(responseData['AuthenticateUserResult']);
console.log(data);
},
error: function (responseData, textStatus, errorThrown) {
alert('POST failed.');
}
});
Interesting. On my 64-bit (i7 Ubuntu) box:

>>> print type(0x7FFFFFFF+1)
<type 'int'>
Guess it steps up to 64 bit ints on a larger machine.
Sometimes Excel will hiccup and needs a kick-start to reapply an equation. This happens in some cases when you are using custom formulas.
Make sure that you have the following script
ActiveSheet.EnableCalculation = True
Reapply the equation of choice.
Cells(RowA,ColB).Formula = Cells(RowA,ColB).Formula
This can then be looped as needed.
You are trying to execute an asynchronous function
in a synchronous way, which is unfortunately not possible in Javascript
.
As you guessed correctly, the roomId=results
.... is executed when the loading from the DB completes, which is done asynchronously, so AFTER the resto of your code is completed.
Look at this article, it talks about .insert and not .find
, but the idea is the same : http://metaduck.com/01-asynchronous-iteration-patterns.html
NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:@"First",@"Second", nil];
NSMutableArray *copiedArray = [array mutableCopy];
NSMutableArray *retainedArray = [array retain];
[retainedArray addObject:@"Retained Third"];
[copiedArray addObject:@"Copied Third"];
NSLog(@"array = %@",array);
NSLog(@"Retained Array = %@",retainedArray);
NSLog(@"Copied Array = %@",copiedArray);
array = (
First,
Second,
"Retained Third"
)
Retained Array = (
First,
Second,
"Retained Third"
)
Copied Array = (
First,
Second,
"Copied Third"
)
As referenced in my answer to Applying rounded corners to paths/polygons, I have written a routine in javascript for generically rounding corners of SVG paths, with examples, here: http://plnkr.co/edit/kGnGGyoOCKil02k04snu.
It will work independently from any stroke effects you may have. To use, include the rounding.js file from the Plnkr and call the function like so:
roundPathCorners(pathString, radius, useFractionalRadius)
The result will be the rounded path.
The results look like this:
Yes, they're in the same "local scope", and actually code like this is common in Python:
if condition:
x = 'something'
else:
x = 'something else'
use(x)
Note that x
isn't declared or initialized before the condition, like it would be in C or Java, for example.
In other words, Python does not have block-level scopes. Be careful, though, with examples such as
if False:
x = 3
print(x)
which would clearly raise a NameError
exception.
If you want to make sure that newly created projects or imported projects in Eclipse use another default java version than Java 1.5, you can change the configuration in the maven-compiler-plugin.
In the following lines:
<source implementation="java.lang.String" default-value="1.5">${maven.compiler.source}</source>
<target implementation="java.lang.String" default-value="1.5">${maven.compiler.target}</target>
change the default-value to 1.6 or 1.8 or whatever you like.
From now on all new Maven projects use the java version you specified.
Information is from the following blog post: https://sandocean.wordpress.com/2019/03/22/directly-generating-maven-projects-in-eclipse-with-java-version-newer-than-1-5/

We use {SmartAssembly} for .NET protection of an enterprise level distributed application, and it has worked great for us.
with
statementDifferentiating between exceptions that occur in a with
statement is tricky because they can originate in different places. Exceptions can be raised from either of the following places (or functions called therein):
ContextManager.__init__
ContextManager.__enter__
with
ContextManager.__exit__
For more details see the documentation about Context Manager Types.
If we want to distinguish between these different cases, just wrapping the with
into a try .. except
is not sufficient. Consider the following example (using ValueError
as an example but of course it could be substituted with any other exception type):
try:
with ContextManager():
BLOCK
except ValueError as err:
print(err)
Here the except
will catch exceptions originating in all of the four different places and thus does not allow to distinguish between them. If we move the instantiation of the context manager object outside the with
, we can distinguish between __init__
and BLOCK / __enter__ / __exit__
:
try:
mgr = ContextManager()
except ValueError as err:
print('__init__ raised:', err)
else:
try:
with mgr:
try:
BLOCK
except TypeError: # catching another type (which we want to handle here)
pass
except ValueError as err:
# At this point we still cannot distinguish between exceptions raised from
# __enter__, BLOCK, __exit__ (also BLOCK since we didn't catch ValueError in the body)
pass
Effectively this just helped with the __init__
part but we can add an extra sentinel variable to check whether the body of the with
started to execute (i.e. differentiating between __enter__
and the others):
try:
mgr = ContextManager() # __init__ could raise
except ValueError as err:
print('__init__ raised:', err)
else:
try:
entered_body = False
with mgr:
entered_body = True # __enter__ did not raise at this point
try:
BLOCK
except TypeError: # catching another type (which we want to handle here)
pass
except ValueError as err:
if not entered_body:
print('__enter__ raised:', err)
else:
# At this point we know the exception came either from BLOCK or from __exit__
pass
The tricky part is to differentiate between exceptions originating from BLOCK
and __exit__
because an exception that escapes the body of the with
will be passed to __exit__
which can decide how to handle it (see the docs). If however __exit__
raises itself, the original exception will be replaced by the new one. To deal with these cases we can add a general except
clause in the body of the with
to store any potential exception that would have otherwise escaped unnoticed and compare it with the one caught in the outermost except
later on - if they are the same this means the origin was BLOCK
or otherwise it was __exit__
(in case __exit__
suppresses the exception by returning a true value the outermost except
will simply not be executed).
try:
mgr = ContextManager() # __init__ could raise
except ValueError as err:
print('__init__ raised:', err)
else:
entered_body = exc_escaped_from_body = False
try:
with mgr:
entered_body = True # __enter__ did not raise at this point
try:
BLOCK
except TypeError: # catching another type (which we want to handle here)
pass
except Exception as err: # this exception would normally escape without notice
# we store this exception to check in the outer `except` clause
# whether it is the same (otherwise it comes from __exit__)
exc_escaped_from_body = err
raise # re-raise since we didn't intend to handle it, just needed to store it
except ValueError as err:
if not entered_body:
print('__enter__ raised:', err)
elif err is exc_escaped_from_body:
print('BLOCK raised:', err)
else:
print('__exit__ raised:', err)
PEP 343 -- The "with" Statement specifies an equivalent "non-with" version of the with
statement. Here we can readily wrap the various parts with try ... except
and thus differentiate between the different potential error sources:
import sys
try:
mgr = ContextManager()
except ValueError as err:
print('__init__ raised:', err)
else:
try:
value = type(mgr).__enter__(mgr)
except ValueError as err:
print('__enter__ raised:', err)
else:
exit = type(mgr).__exit__
exc = True
try:
try:
BLOCK
except TypeError:
pass
except:
exc = False
try:
exit_val = exit(mgr, *sys.exc_info())
except ValueError as err:
print('__exit__ raised:', err)
else:
if not exit_val:
raise
except ValueError as err:
print('BLOCK raised:', err)
finally:
if exc:
try:
exit(mgr, None, None, None)
except ValueError as err:
print('__exit__ raised:', err)
The need for such special exception handling should be quite rare and normally wrapping the whole with
in a try ... except
block will be sufficient. Especially if the various error sources are indicated by different (custom) exception types (the context managers need to be designed accordingly) we can readily distinguish between them. For example:
try:
with ContextManager():
BLOCK
except InitError: # raised from __init__
...
except AcquireResourceError: # raised from __enter__
...
except ValueError: # raised from BLOCK
...
except ReleaseResourceError: # raised from __exit__
...

Initiate the NodeList inside the for loop and you will get the desired output.
ArrayList<String> nodes = new ArrayList<String>();
ArrayList list=new ArrayList();
for(int i=0;i<PropertyNode.getLength()-1;i++){
ArrayList NodeList=new ArrayList();
Node childNode = PropertyNode.item(i);
NodeList Children = childNode.getChildNodes();
if(Children!=null){
nodes.clear();
nodes.add("PropertyStart");
nodes.add(Children.item(3).getTextContent());
nodes.add(Children.item(7).getTextContent());
nodes.add(Children.item(9).getTextContent());
nodes.add(Children.item(11).getTextContent());
nodes.add(Children.item(13).getTextContent());
nodes.add("PropertyEnd");
}
NodeList.addAll(nodes);
list.add(NodeList);
}
Explanation: NodeList is an object which remains same throughout the loop so adding same variable to list in a loop will actually add it only once. The loop is only adding its variables in single NodeList array hence you must be seeing
[/*list*/ [ /*NodeList*/ ] ]
and NodeList contains [prostart, a,b,c,proend,prostart,d,e,f,proend ...]
To differentiate between scroll up/down in jQuery, you could use:
var mousewheelevt = (/Firefox/i.test(navigator.userAgent)) ? "DOMMouseScroll" : "mousewheel" //FF doesn't recognize mousewheel as of FF3.x
$('#yourDiv').bind(mousewheelevt, function(e){
var evt = window.event || e //equalize event object
evt = evt.originalEvent ? evt.originalEvent : evt; //convert to originalEvent if possible
var delta = evt.detail ? evt.detail*(-40) : evt.wheelDelta //check for detail first, because it is used by Opera and FF
if(delta > 0) {
//scroll up
}
else{
//scroll down
}
});
This method also works in divs that have overflow:hidden
.
I successfully tested it in FireFox, IE and Chrome.
Unlike ssh, scp uses the uppercase P switch to set the port instead of the lowercase p:
scp -P 80 ... # Use port 80 to bypass the firewall, instead of the scp default
The lowercase p switch is used with scp for the preservation of times and modes.
Here is an excerpt from scp's man page with all of the details concerning the two switches, as well as an explanation of why uppercase P was chosen for scp:
-P port Specifies the port to connect to on the remote host. Note that this option is written with a capital 'P', because -p is already reserved for preserving the times and modes of the file in rcp(1).
-p Preserves modification times, access times, and modes from the original file.
Update and aside to address one of the (heavily upvoted) comments:
With regard to Abdull's comment about scp
option order, what he suggests:
scp -P80 -r some_directory -P 80 ...
..., intersperses options and parameters. getopt(1)
clearly defines that parameters must come after options and not be interspersed with them:
The parameters getopt is called with can be divided into two parts: options which modify the way getopt will do the parsing (the options and the optstring in the SYNOPSIS), and the parameters which are to be parsed (parameters in the SYNOPSIS). The second part will start at the first non-option parameter that is not an option argument, or after the first occurrence of '--'. If no '-o' or '--options' option is found in the first part, the first parameter of the second part is used as the short options string.
Since the -r
command line option takes no further arguments, some_directory
is "the first non-option parameter that is not an option argument." Therefore, as clearly spelled out in the getopt(1)
man page, all succeeding command line arguments that follow it (i.e., -P 80 ...
) are assumed to be non-options (and non-option arguments).
So, in effect, this is how getopt(1)
sees the example presented with the end of the options and the beginning of the parameters demarcated by succeeding text bing in gray:
scp -P80 -r some_directory -P 80 ...
This has nothing to do with scp
behavior and everything to do with how POSIX standard applications parse command line options using the getopt(3)
set of C functions.
For more details with regard to command line ordering and processing, please read the getopt(1)
manpage using:
man 1 getopt
Expand the SQL Server Agent node and right click the Jobs node in SQL Server Agent and select 'New Job'
In the 'New Job'

You can specify '-m32' or '-m64' to select the compilation mode.
When dealing with autoconf (configure) scripts, I usually set CC="gcc -m64" (or CC="gcc -m32") in the environment so that everything is compiled with the correct bittiness. At least, usually...people find endless ways to make that not quite work, but my batting average is very high (way over 95%) with it.

Alternatively, you can proxy their result. Create an endpoint on your server, and have that endpoint open a connection to the target endpoint, and simply funnel traffic backwards.

Working off of what @Gishu did I was able to produce and use the following SQL in SQL Server 2005
SELECT t.name AS TableWithForeignKey, fk.constraint_column_id AS FK_PartNo,
c.name AS ForeignKeyColumn, o.name AS FK_Name
FROM sys.foreign_key_columns AS fk
INNER JOIN sys.tables AS t ON fk.parent_object_id = t.object_id
INNER JOIN sys.columns AS c ON fk.parent_object_id = c.object_id
AND fk.parent_column_id = c.column_id
INNER JOIN sys.objects AS o ON fk.constraint_object_id = o.object_id
WHERE fk.referenced_object_id = (SELECT object_id FROM sys.tables
WHERE name = 'TableOthersForeignKeyInto')
ORDER BY TableWithForeignKey, FK_PartNo;
Which Displays the tables, columns and Foreign Key names all in 1 query.

There are two big difference the sorting and the character matching:
Sorting:
utf8mb4_general_ci
removes all accents and sorts one by one which may create incorrect sort results.utf8mb4_unicode_ci
sorts accurate.Character Matching
They match characters differently.
For example, in utf8mb4_unicode_ci
you have i != i
, but in utf8mb4_general_ci
it holds i=i
.
For example, imagine you have a row with name="Yilmaz"
. Then
select id from users where name='Yilmaz';
would return the row if collocation is utf8mb4_general_ci
, but if it is collocated with utf8mb4_unicode_ci
it would not return the row!
On the other hand we have that a=ª
and ß=ss
in utf8mb4_unicode_ci
which is not the case in utf8mb4_general_ci
. So imagine you have a row with name="ªßi"
, then
select id from users where name='assi';
would return the row if collocation is utf8mb4_unicode_ci
, but would not return a row if collocation is set to utf8mb4_general_ci
.
A full list of matches for each collocation may be found here.
Although the given list comprehension / generator expression answers are ok, I find this easier to read and understand:

In modern browsers (IE8, Firefox, Chrome, Opera, Safari) you can use querySelector()
:
function test(el){
el.querySelector("#child").style.display = "none";
}
For older browsers (<=IE7), you would have to use some sort of library, such as Sizzle or a framework, such as jQuery, to work with selectors.
As mentioned, IDs are supposed to be unique within a document, so it's easiest to just use document.getElementById("child")
.
I did this research the last week and I ended up with the same 2 libraries. As I'm using Spring 3 (that adopts Jackson in its default Json view 'JacksonJsonView') it was more natural for me to do the same. The 2 lib are pretty much the same... at the end they simply map to a json file! :)
Anyway as you said Jackson has a + in performance and that's very important for me. The project is also quite active as you can see from their web page and that's a very good sign as well.

HTML code for sizing images (internal/external):
<img src="https://github.com/favicon.ico" width="48">
Example:
This should work:
[[ http://url.to/image.png | height = 100px ]]
Source: https://guides.github.com/features/mastering-markdown/
SELECT CAST(height AS DECIMAL(18,0)) / 10
Edit: How this works under the hood?
The result type is the same as the type of both arguments, or, if they are different, it is determined by the data type precedence table. You can therefore cast either argument to something non-integral.
Now DECIMAL(18,0)
, or you could equivalently write just DECIMAL
, is still a kind of integer type, because that default scale of 0
means "no digits to the right of the decimal point". So a cast to it might in different circumstances work well for rounding to integers - the opposite of what we are trying to accomplish.
However, DECIMALs have their own rules for everything. They are generally non-integers, but always exact numerics. The result type of the DECIMAL division that we forced to occur is determined specially to be, in our case, DECIMAL(29,11). The result of the division will therefore be rounded to 11 places which is no concern for division by 10, but the rounding becomes observable when dividing by 3. You can control the amount of rounding by manipulating the scale of the left hand operand. You can also round more, but not less, by placing another ROUND or CAST operation around the whole expression.
Identical mechanics governs the simpler and nicer solution in the accepted answer:
SELECT height / 10.0
In this case, the type of the divisor is DECIMAL(3,1)
and the type of the result is DECIMAL(17,6)
. Try dividing by 3 and observe the difference in rounding.
If you just hate all this talk of precisions and scales, and just want SQL server to perform all calculations in good old double precision floating point arithmetics from some point on, you can force that, too:
SELECT height / CAST(10 AS FLOAT(53))
or equivalently just
SELECT height / CAST (10 AS FLOAT)
I think to get a complete answer, people have to know how enums work internally in .NET.
How stuff works
An enum in .NET is a structure that maps a set of values (fields) to a basic type (the default is int
). However, you can actually choose the integral type that your enum maps to:
public enum Foo : short
In this case the enum is mapped to the short
data type, which means it will be stored in memory as a short and will behave as a short when you cast and use it.
If you look at it from a IL point of view, a (normal, int) enum looks like this:
.class public auto ansi serializable sealed BarFlag extends System.Enum
{
.custom instance void System.FlagsAttribute::.ctor()
.custom instance void ComVisibleAttribute::.ctor(bool) = { bool(true) }
.field public static literal valuetype BarFlag AllFlags = int32(0x3fff)
.field public static literal valuetype BarFlag Foo1 = int32(1)
.field public static literal valuetype BarFlag Foo2 = int32(0x2000)
// and so on for all flags or enum values
.field public specialname rtspecialname int32 value__
}
What should get your attention here is that the value__
is stored separately from the enum values. In the case of the enum Foo
above, the type of value__
is int16. This basically means that you can store whatever you want in an enum, as long as the types match.
At this point I'd like to point out that System.Enum
is a value type, which basically means that BarFlag
will take up 4 bytes in memory and Foo
will take up 2 -- e.g. the size of the underlying type (it's actually more complicated than that, but hey...).
The answer
So, if you have an integer that you want to map to an enum, the runtime only has to do 2 things: copy the 4 bytes and name it something else (the name of the enum). Copying is implicit because the data is stored as value type - this basically means that if you use unmanaged code, you can simply interchange enums and integers without copying data.
To make it safe, I think it's a best practice to know that the underlying types are the same or implicitly convertible and to ensure the enum values exist (they aren't checked by default!).
To see how this works, try the following code:
public enum MyEnum : int
{
Foo = 1,
Bar = 2,
Mek = 5
}
static void Main(string[] args)
{
var e1 = (MyEnum)5;
var e2 = (MyEnum)6;
Console.WriteLine("{0} {1}", e1, e2);
Console.ReadLine();
}
Note that casting to e2
also works! From the compiler perspective above this makes sense: the value__
field is simply filled with either 5 or 6 and when Console.WriteLine
calls ToString()
, the name of e1
is resolved while the name of e2
is not.
If that's not what you intended, use Enum.IsDefined(typeof(MyEnum), 6)
to check if the value you are casting maps to a defined enum.
Also note that I'm explicit about the underlying type of the enum, even though the compiler actually checks this. I'm doing this to ensure I don't run into any surprises down the road. To see these surprises in action, you can use the following code (actually I've seen this happen a lot in database code):
public enum MyEnum : short
{
Mek = 5
}
static void Main(string[] args)
{
var e1 = (MyEnum)32769; // will not compile, out of bounds for a short
object o = 5;
var e2 = (MyEnum)o; // will throw at runtime, because o is of type int
Console.WriteLine("{0} {1}", e1, e2);
Console.ReadLine();
}
For excellent code-readability, Fest Assertions has nice support for asserting lists
So in this case, something like:
Assertions.assertThat(returnedComponents).containsExactly("One", "Two", "Three");
Or make the expected list to an array, but I prefer the above approach because it's more clear.
Assertions.assertThat(returnedComponents).containsExactly(argumentComponents.toArray());

Here is a Live Example About it
It's as simple as:
if (value.compareTo(BigDecimal.ZERO) > 0)
The documentation for compareTo
actually specifies that it will return -1, 0 or 1, but the more general Comparable<T>.compareTo
method only guarantees less than zero, zero, or greater than zero for the appropriate three cases - so I typically just stick to that comparison.
re: indexOutOfBoundsException
, your sublist args are the problem; you need to end the sublist at size-1. Being zero-based, the last element of a list is always size-1, there is no element in the size position, hence the error.
The Node REPL uses the underscore variable to hold the result of the last operation, so it conflicts with the Underscore library's use of the same variable. Try something like this:
Admin-MacBook-Pro:test admin$ node

{ [Function]
_: [Circular],
VERSION: '1.1.4',
forEach: [Function],
each: [Function],
map: [Function],
inject: [Function],
(...more functions...)
templateSettings: { evaluate: /<%([\s\S]+?)%>/g, interpolate: /<%=([\s\S]+?)%>/g },
template: [Function] }
> _und.max([1,2,3])

If you just do eval $cmd
when we do cmd="ls -l"
(interactively and in a script) we get the desired result. In your case, you have a pipe with a grep without a pattern, so the grep part will fail with an error message. Just $cmd
will generate a "command not found" (or some such) message.
So try use eval and use a finished command, not one that generates an error message.
All the above method will work. but to use the var as env variable inside your code you need to export the var first.
script{
sh " 'shell command here' > command"
command_var = readFile('command').trim()
sh "export command_var=$command_var"
}
replace the shell command with the command of your choice. Now if you are using python code you can just specify os.getenv("command_var") that will return the output of the shell command executed previously.
Got my own answer: Using this function from the data from the textarea solves the problem:

The only way I could actually stop git form tracking the folder was to do the following:
git rm -r --cached your_folder/

to .gitignoreYou should now see that the folder is no longer tracked.
Don't ask me why just clearing the cache didn't work for me, I am not a Git super wizard but this is how I solved the issue.
It means you have a null reference somewhere in there. Can you debug the app and stop the debugger when it gets here and investigate? Probably img1

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming
Update March 2013
Git 1.8.2 added the possibility to track branches.
"
git submodule
" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).
# add submodule to track master branch
git submodule add -b master [URL to Git repo];
# update your submodule
git submodule update --remote
If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".
Also see Vogella's tutorial on submodules for general information on submodules.
Note:
git submodule add -b . [URL to Git repo];
^^^
A special value of
.
is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.
See commit b928922727d6691a3bdc28160f93f25712c565f6:
submodule add
: If --branch
is given, record it in .gitmodules
This allows you to easily record a
submodule.<name>.branch
option in.gitmodules
when you add a new submodule. With this patch,
$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>
reduces to
$ git submodule add -b <branch> <repository> [<path>]
This means that future calls to
$ git submodule update --remote ...
will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):
A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log
within that submodule.
So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:
gitslave (that you already looked at) seems to be the best fit, including for the commit operation.
It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).
Other alternatives are detailed here.
A deferred can be used in place of a mutex. This is essentially the same as the multiple ajax usage scenarios.
MUTEX
var mutex = 2;
setTimeout(function() {
callback();
}, 800);
setTimeout(function() {
callback();
}, 500);
function callback() {
if (--mutex === 0) {
//run code
}
}
DEFERRED
function timeout(x) {
var dfd = jQuery.Deferred();
setTimeout(function() {
dfd.resolve();
}, x);
return dfd.promise();
}
jQuery.when(
timeout(800), timeout(500)).done(function() {
// run code
});
When using a Deferred as a mutex only, watch out for performance impacts (http://jsperf.com/deferred-vs-mutex/2). Though the convenience, as well as additional benefits supplied by a Deferred is well worth it, and in actual (user driven event based) usage the performance impact should not be noticeable.

Do you mean like this
int index = 2;
string s = "hello";
Console.WriteLine(s[index]);
string also implements IEnumberable<char>
so you can also enumerate it like this
foreach (char c in s)
Console.WriteLine(c);

textField.selectAll();
}
This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.
The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)
char *words; // setting this to NULL would have prevented the issue
if (condition) {
words = malloc( 512 );
/* calling free sometime later works here */
free(words)
} else {
/* do not allocate words in this branch */
}
/* free(words); -- error here --

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:
*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.
Most mocking frameworks (Moq and RhinoMocks included) generate proxy classes as a substitute for your mocked class, and override the virtual methods with behavior that you define. Because of this, you can only mock interfaces, or virtual methods on concrete or abstract classes. Additionally, if you're mocking a concrete class, you almost always need to provide a parameterless constructor so that the mocking framework knows how to instantiate the class.
Why the aversion to creating interfaces in your code?
My overlays disappeared all of a sudden (or so I thought). I came across this article https://corengen.wordpress.com/2014/07/30/my-tortoisesvn-icon-overlays-have-disappeared/ which points out that windows has 15 slots for overlay icons; 4 are reserved for windows, which leaves 11 for other applications. Regardless of how many overlay keys are in the registry, Windows selects the first 11 in alphabetical order.
When I upgraded Office, OneDrive added overlay icons -- prefixed with a lot of spaces -- pushing down Tortoise's overlays below the threshold: windows registry Since I am not using OneDrive, the solution was to add a "z" to the OneDrive key names.
CSS Styles are key-value pairs, not just "tags". By default, each element has a full set of CSS styles assigned to it, most of them is implicitly using the browser defaults and some of them is explicitly redefined in CSS stylesheets.
To get the value assigned to a particular CSS entry of an element and compare it:
if ($('#yourElement').css('position') == 'absolute')
{
// true
}
If you didn't redefine the style, you will get the browser default for that particular element.
Nope IF is the way to go, what is the problem you have with using it?
BTW your example won't ever get to the third block of code as it and the second block are exactly alike.
is_numeric would accept "-0.5e+12" as a valid ID.
So if want to set the value of an environment variable to something different for every build then we can pass these values during build time and we don't need to change our docker file every time.
While ENV
, once set cannot be overwritten through command line values. So, if we want to have our environment variable to have different values for different builds then we could use ARG
and set default values in our docker file. And when we want to overwrite these values then we can do so using --build-args
at every build without changing our docker file.
For more details, you can refer this.
Try this
void Function()
{
while (condition)
{
await Task.Delay(1);
}
}
This will make the program wait until the condition is not true. You can just invert it by adding a "!" infront of the condition so that it will wait until the condition is true.
This one worked for me in the bash file.
git branch | grep '^*' | sed 's/* //'
################bash file###################
#!/bin/bash
BRANCH=$(git branch | grep '^*' | sed 's/* //' )
echo $BRANCH
var month = new Date().getMonth();
var newmon = month + 1;
$('#month').html((newmon < 10 ? '0' : '') + newmon );
I simply fixed your month issue, getMonth array start from 0 to 11.
I just posted this to my brand spanking new blog: http://jasonturim.wordpress.com/2013/09/01/angularjs-drag-and-drop/
Code here: https://github.com/logicbomb/lvlDragDrop
Demo here: http://logicbomb.github.io/ng-directives/drag-drop.html
Here are the directives these rely on a UUID service which I've included below:
var module = angular.module("lvl.directives.dragdrop", ['lvl.services']);
module.directive('lvlDraggable', ['$rootScope', 'uuid', function($rootScope, uuid) {
return {
restrict: 'A',
link: function(scope, el, attrs, controller) {
console.log("linking draggable element");
angular.element(el).attr("draggable", "true");
var id = attrs.id;
if (!attrs.id) {
id = uuid.new()
angular.element(el).attr("id", id);
}
el.bind("dragstart", function(e) {
e.dataTransfer.setData('text', id);
$rootScope.$emit("LVL-DRAG-START");
});
el.bind("dragend", function(e) {
$rootScope.$emit("LVL-DRAG-END");
});
}
}
}]);
module.directive('lvlDropTarget', ['$rootScope', 'uuid', function($rootScope, uuid) {
return {
restrict: 'A',
scope: {
onDrop: '&'
},
link: function(scope, el, attrs, controller) {
var id = attrs.id;
if (!attrs.id) {
id = uuid.new()
angular.element(el).attr("id", id);
}
el.bind("dragover", function(e) {
if (e.preventDefault) {
e.preventDefault(); // Necessary. Allows us to drop.
}
e.dataTransfer.dropEffect = 'move'; // See the section on the DataTransfer object.
return false;
});
el.bind("dragenter", function(e) {
// this / e.target is the current hover target.
angular.element(e.target).addClass('lvl-over');
});
el.bind("dragleave", function(e) {
angular.element(e.target).removeClass('lvl-over'); // this / e.target is previous target element.
});
el.bind("drop", function(e) {
if (e.preventDefault) {
e.preventDefault(); // Necessary. Allows us to drop.
}
if (e.stopPropagation) {
e.stopPropagation(); // Necessary. Allows us to drop.
}
var data = e.dataTransfer.getData("text");
var dest = document.getElementById(id);
var src = document.getElementById(data);
scope.onDrop({dragEl: src, dropEl: dest});
});
$rootScope.$on("LVL-DRAG-START", function() {
var el = document.getElementById(id);
angular.element(el).addClass("lvl-target");
});
$rootScope.$on("LVL-DRAG-END", function() {
var el = document.getElementById(id);
angular.element(el).removeClass("lvl-target");
angular.element(el).removeClass("lvl-over");
});
}
}
}]);
UUID service
angular
.module('lvl.services',[])
.factory('uuid', function() {
var svc = {
new: function() {
function _p8(s) {
var p = (Math.random().toString(16)+"000000000").substr(2,8);
return s ? "-" + p.substr(0,4) + "-" + p.substr(4,4) : p ;
}
return _p8() + _p8(true) + _p8(true) + _p8();
},
empty: function() {
return '00000000-0000-0000-0000-000000000000';
}
};
return svc;
});
I'd suggest using $_POST
and $_GET
explicitly.
Using $_REQUEST should be unnecessary with proper site design anyway, and it comes with some downsides like leaving you open to easier CSRF/XSS
attacks and other silliness that comes from storing data in the URL.
The speed difference should be minimal either way.
Use Decimal.Truncate
It removes the fractional part from the decimal.
int i = (int)Decimal.Truncate(12.66m)
A popular method to tackle the problem of reducing JavaScript references from HTML files is by using a concatenation tool like Sprockets, which preprocesses and concatenates JavaScript source files together.
Apart from reducing the number of references from the HTML files, this will also reduce the number of hits to the server.
You may then want to run the resulting concatenation through a minification tool like jsmin to have it minified.
Now no need third party classes ios 5 introduced Nsjsonserialization
NSString *urlString=@"Your url";
NSString *urlUTF8 = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url=[[NSURL alloc]initWithString:urlUTF8];
NSURLRequest *request=[NSURLRequest requestWithURL:url];
NSURLResponse *response;
NSData *GETReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
NSError *myError = nil;
NSDictionary *res = [NSJSONSerialization JSONObjectWithData:GETReply options:NSJSONReadingMutableLeaves|| NSJSONReadingMutableContainers error:&myError];
Nslog(@"%@",res);
this code can useful for getting jsondata.
