Create a lookup table first:
morse = [None] * (ord('z') - ord('a') + 1)
for line in moreCodeFile:
morse[ord(line[0].lower()) - ord('a')] = line[2:]
Then convert using the table:
for ch in userInput:
print morse[ord(ch.lower()) - ord('a')]
I've found out a nice workaround to IP blocking when scraping sites. It lets you run a Scraper indefinitely by running it from Google App Engine and redeploying it automatically when you get a 429.

As I wrote in my comment, the solution to your problem is to write the following:
Set hyperLinkText = hprlink.Range
Set
is needed because TextRange
is a class, so hyperLinkText
is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.
Your friend's PC is missing the runtime support DLLs for your program:
I use an extension method for this. My extension method first checks to see if the enumeration is null and if so creates an empty list. This allows you to do a foreach on it without explicitly having to check for null.
Here is a very contrived example:
IEnumerable<string> stringEnumerable = null;
StringBuilder csv = new StringBuilder();
stringEnumerable.ToNonNullList().ForEach(str=> csv.Append(str).Append(","));
Here is the extension method:
public static List<T> ToNonNullList<T>(this IEnumerable<T> obj)
{
return obj == null ? new List<T>() : obj.ToList();
}
Yes, the Jackson manual parser design is quite different from other libraries. In particular, you will notice that JsonNode
has most of the functions that you would typically associate with array nodes from other API's. As such, you do not need to cast to an ArrayNode
to use. Here's an example:
JSON:
{
"objects" : ["One", "Two", "Three"]
}
Code:
final String json = "{\"objects\" : [\"One\", \"Two\", \"Three\"]}";
final JsonNode arrNode = new ObjectMapper().readTree(json).get("objects");
if (arrNode.isArray()) {
for (final JsonNode objNode : arrNode) {
System.out.println(objNode);
}
}
Output:
"One"
"Two"
"Three"
Note the use of isArray
to verify that the node is actually an array before iterating. The check is not necessary if you are absolutely confident in your datas structure, but its available should you need it (and this is no different from most other JSON libraries).
I think init_js should use declare instead of local!
function scan3() {
declare -n outvar=$1 # -n makes it a nameref.
local nl=$'\x0a'
outvar="output${nl}${nl}" # two total. quotes preserve newlines
}
function getRandomColor()
{
var color = "#";
for (var i = 0; i < 3; i++)
{
var part = Math.round(Math.random() * 255).toString(16);
color += (part.length > 1) ? part : "0" + part;
}
return color;
}
Should be:
curl --cert certificate_file.pem:password https://www.example.com/some_protected_page
json
is simplejson
, added to the stdlib. But since json
was added in 2.6, simplejson
has the advantage of working on more Python versions (2.4+).
simplejson
is also updated more frequently than Python, so if you need (or want) the latest version, it's best to use simplejson
itself, if possible.
A good practice, in my opinion, is to use one or the other as a fallback.
try:
import simplejson as json
except ImportError:
import json

You can use GCC on Windows by downloading MingW (discontinued) or its successor Mingw-w64.
Complete copy&paste recipe, just adding the commands in the comments (for the copy-paste solution), after testing them:
git filter-branch --tree-filter 'rm -rf node_modules' --prune-empty HEAD
echo node_modules/ >> .gitignore
git add .gitignore
git commit -m 'Removing node_modules from git history'
git gc
git push origin master --force
After this, you can remove the line "node_modules/" from .gitignore
$total_ratings
is an array, which you can't use for a division.
From above:
$total_ratings = mysqli_fetch_array($result);
The solution is in your build.gradle change this block:
allprojects {
repositories {
jcenter()
google()
}
}
to google in first position :
allprojects {
repositories {
google()
jcenter()
}
}
Another issue you have to take care of: If your generated file names are not the default id_rsa
and id_rsa.pub
.
You have to create the .ssh/config file and define manually which id file you are going to use with the connection.
An example is here:
Host remote_host_name
HostName 172.xx.xx.xx
User my_user
IdentityFile /home/my_user/.ssh/my_user_custom

http://allu.wordpress.com/2006/11/08/difference-between-final-finally-and-finalize/
final – constant declaration.
finally – The finally block always executes when the try block exits, except System.exit(0) call. This ensures that the finally block is executed even if an unexpected exception occurs. But finally is useful for more than just exception handling — it allows the programmer to avoid having cleanup code accidentally bypassed by a return, continue, or break. Putting cleanup code in a finally block is always a good practice, even when no exceptions are anticipated.
finalize() – method helps in garbage collection. A method that is invoked before an object is discarded by the garbage collector, allowing it to clean up its state. Should not be used to release non-memory resources like file handles, sockets, database connections etc because Java has only a finite number of these resources and you do not know when the garbage collection is going to kick in to release these non-memory resources through the finalize() method.
Did you try searching on google, and need clarification for an explanation?
I was just looking for a smiliar issue and I found this:
.div{
height : 100vh;
}
more info
vw: 1/100th viewport width
vh: 1/100th viewport height
vmin: 1/100th of the smallest side
vmax: 1/100th of the largest side
Continuing this answer, There is another difference that if you want your method to return different values for example when it is first time called, second time called etc then you can pass values so for example...
PowerMockito.doReturn(false, false, true).when(SomeClass.class, "SomeMethod", Matchers.any(SomeClass.class));
So it will return false when the method is called in same test case and then it will return false again and lastly true.
Your assignment has an extra $
:
export PATH=$PATH:${PWD}:/foo/bar
I would EXPECT the first query to be quicker, mainly because you have an equivalence and an explicit JOIN. In my experience IN
is a very slow operator, since SQL normally evaluates it as a series of WHERE
clauses separated by "OR" (WHERE x=Y OR x=Z OR...
).
As with ALL THINGS SQL though, your mileage may vary. The speed will depend a lot on indexes (do you have indexes on both ID columns? That will help a lot...) among other things.
The only REAL way to tell with 100% certainty which is faster is to turn on performance tracking (IO Statistics is especially useful) and run them both. Make sure to clear your cache between runs!
Calling .html()
serializes the element to a string, so all event handlers and other associated data is lost. Here's how I'd do it:
$("#myButton").click(function ()
{
var test = $('<button/>',
{
text: 'Test',
click: function () { alert('hi'); }
});
var parent = $('<tr><td></td></tr>').children().append(test).end();
$("#addNodeTable tr:last").before(parent);
});
Or,
$("#myButton").click(function ()
{
var test = $('<button/>',
{
text: 'Test',
click: function () { alert('hi'); }
}).wrap('<tr><td></td></tr>').closest('tr');
$("#addNodeTable tr:last").before(test);
});
If you don't like passing a map of properties to $()
, you can instead use
$('<button/>')
.text('Test')
.click(function () { alert('hi'); });
// or
$('<button>Test</button>').click(function () { alert('hi'); });
I had problems installing the 64-bit version of MySQLdb on Windows via Pip (problem compiling sources) [32bit version installed ok]. Managed to install the compiled MySQLdb from the .whl file available from http://www.lfd.uci.edu/~gohlke/pythonlibs/
The .whl file can then be installed via pip as document in https://pip.pypa.io/en/latest/user_guide/#installing-from-wheels
For example if you save in C:/
the you can install via
pip install c:/MySQL_python-1.2.5-cp27-none-win_amd64.whl
Follow-up: if you have a 64bit version of Python installed, then you want to install the 64-bit AMD version of MySQLdb from the link above [i.e. even if you have a Intel processor]. If you instead try and install the 32-bit version, I think you get the unsupported wheel error in comments below.
For Universal Solution, Here was my approach for implementing IQKeyboardManager.
Step1:- I Added global notifications of UITextField
, UITextView
, and UIKeyboard
in a singleton class. I call it IQKeyboardManager.
Step2:- If found UIKeyboardWillShowNotification
, UITextFieldTextDidBeginEditingNotification
or UITextViewTextDidBeginEditingNotification
notifications, I try to get topMostViewController
instance from the UIWindow.rootViewController
hierarchy. In order to properly uncover UITextField
/UITextView
on it, topMostViewController.view
's frame needs to be adjusted.
Step3:- I calculated expected move distance of topMostViewController.view
with respect to first responded UITextField
/UITextView
.
Step4:- I moved topMostViewController.view.frame
up/down according to the expected move distance.
Step5:- If found UIKeyboardWillHideNotification
, UITextFieldTextDidEndEditingNotification
or UITextViewTextDidEndEditingNotification
notification, I again try to get topMostViewController
instance from the UIWindow.rootViewController
hierarchy.
Step6:- I calculated disturbed distance of topMostViewController.view
which needs to be restored to it's original position.
Step7:- I restored topMostViewController.view.frame
down according to the disturbed distance.
Step8:- I instantiated singleton IQKeyboardManager class instance on app load, so every UITextField
/UITextView
in the app will adjust automatically according to the expected move distance.
That's all IQKeyboardManager do for you with NO LINE OF CODE really!! only need to drag and drop related source file to project. IQKeyboardManager also support Device Orientation, Automatic UIToolbar Management, KeybkeyboardDistanceFromTextField and much more than you think.
When you say
(a['x']==1) and (a['y']==10)
You are implicitly asking Python to convert (a['x']==1)
and (a['y']==10)
to boolean values.
NumPy arrays (of length greater than 1) and Pandas objects such as Series do not have a boolean value -- in other words, they raise
ValueError: The truth value of an array is ambiguous. Use a.empty, a.any() or a.all().
when used as a boolean value. That's because its unclear when it should be True or False. Some users might assume they are True if they have non-zero length, like a Python list. Others might desire for it to be True only if all its elements are True. Others might want it to be True if any of its elements are True.
Because there are so many conflicting expectations, the designers of NumPy and Pandas refuse to guess, and instead raise a ValueError.
Instead, you must be explicit, by calling the empty()
, all()
or any()
method to indicate which behavior you desire.
In this case, however, it looks like you do not want boolean evaluation, you want element-wise logical-and. That is what the &
binary operator performs:
(a['x']==1) & (a['y']==10)
returns a boolean array.
By the way, as alexpmil notes,
the parentheses are mandatory since &
has a higher operator precedence than ==
.
Without the parentheses, a['x']==1 & a['y']==10
would be evaluated as a['x'] == (1 & a['y']) == 10
which would in turn be equivalent to the chained comparison (a['x'] == (1 & a['y'])) and ((1 & a['y']) == 10)
. That is an expression of the form Series and Series
.
The use of and
with two Series would again trigger the same ValueError
as above. That's why the parentheses are mandatory.

monthString = new DateFormatSymbols().getMonths()[month-1];
Alternatively, you could use SimpleDateFormat:
import java.text.SimpleDateFormat;
System.out.println(new SimpleDateFormat("MMMM").format(date));
(You'll have to put a date with your month in a Date
object to use the second option).

Another thing is - if your keys are very complicated sometimes you need to replace the places of the fields and it helps :
if this dosent work:
foreign key (ISBN, Title) references BookTitle (ISBN, Title)
Then this might work (not for this specific example but in general) :
foreign key (Title,ISBN) references BookTitle (Title,ISBN)
If you importing some other project in xcode and if current and import project both have same files in Compiler source then just remove same file in current project in "Build phase' settings. It worked for me.
An IEnumerator
is a thing that can enumerate: it has the Current
property and the MoveNext
and Reset
methods (which in .NET code you probably won't call explicitly, though you could).
An IEnumerable
is a thing that can be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator
.
Which do you use? The only reason to use IEnumerator
is if you have something that has a nonstandard way of enumerating (that is, of returning its various elements one-by-one), and you need to define how that works. You'd create a new class implementing IEnumerator
. But you'd still need to return that IEnumerator
in an IEnumerable
class.
For a look at what an enumerator (implementing IEnumerator<T>
) looks like, see any Enumerator<T>
class, such as the ones contained in List<T>
, Queue<T>,
or Stack<T>
. For a look at a class implementing IEnumerable
, see any standard collection class.
When dividing two integers, e.g.,
int c = (int) a / (int) b;
the result is an int
, the value of which is a
divided by b
, rounded toward zero. Because the result is already rounded, ceil()
doesn't do anything. Note that this rounding is not the same as floor()
, which rounds towards negative infinity. So, 3/2
equals 1
(and floor(1.5)
equals 1.0
, but (-3)/2
equals -1
(but floor(-1.5)
equals -2.0
).
This is significant because if a/b
were always the same as floor(a / (double) b)
, then you could just implement ceil()
of a/b
as -( (-a) / b)
.
The suggestion of getting ceil(a/b)
from
int n = (a + b - 1) / b;
, which is equivalent to a / b + (b - 1) / b
, or (a - 1) / b + 1
works because ceil(a/b)
is always one greater than floor(a/b)
, except when a/b
is a whole number. So, you want to bump it to (or past) the next whole number, unless a/b
is a whole number. Adding 1 - 1 / b
will do this. For whole numbers, it won't quite push them up to the next whole number. For everything else, it will.
Yikes. Hopefully that makes sense. I'm sure there's a more mathematically elegant way to explain it.

rising_edge is defined as:
FUNCTION rising_edge (SIGNAL s : std_ulogic) RETURN BOOLEAN IS
BEGIN
RETURN (s'EVENT AND (To_X01(s) = '1') AND
(To_X01(s'LAST_VALUE) = '0'));
END;
FUNCTION To_X01 ( s : std_ulogic ) RETURN X01 IS
BEGIN
RETURN (cvt_to_x01(s));
END;
CONSTANT cvt_to_x01 : logic_x01_table := (
'X', -- 'U'
'X', -- 'X'
'0', -- '0'
'1', -- '1'
'X', -- 'Z'
'X', -- 'W'
'0', -- 'L'
'1', -- 'H'
'X' -- '-'
);
If your clock only goes from 0 to 1, and from 1 to 0, then rising_edge will produce identical code. Otherwise, you can interpret the difference.
Personally, my clocks only go from 0 to 1 and vice versa. I find rising_edge(clk)
to be more descriptive than the (clk'event and clk = '1')
variant.
I normally use the killall

Use this:
string uri = ...;
string queryString = new System.Uri(uri).Query;

string.Join(string.Empty, uri.Split('?').Skip(1));
In my case, i do:
sudo nano /etc/mysql/my.cnf

names and IPsYour problem is that, if the user clicks cancel, operationType
is null and thus throws a NullPointerException. I would suggest that you move
if (operationType.equalsIgnoreCase("Q"))
to the beginning of the group of if statements, and then change it to
if(operationType==null||operationType.equalsIgnoreCase("Q")).
This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.
Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

I highly recommend reading the book 'Effective Java' from Joshua Bloch.
Quite often the issue is a non-breaking space - CHAR(160)
- especially from Web text sources -that CLEAN
can't remove, so I would go a step further than this and try a formula like this which replaces any non-breaking spaces with a standard one
=TRIM(CLEAN(SUBSTITUTE(A1,CHAR(160)," ")))
Ron de Bruin has an excellent post on tips for cleaning data here
You can also remove the CHAR(160)
directly without a workaround formula by
ALT
and type 0160
using the numeric keypadfibo = f.fibo
references the class itself. You probably wanted fibo = f.fibo()
(note the parentheses) to make an instance of the class, after which fibo.f()
should succeed correctly.
f.fibo.f()
fails because you are essentially calling f(self, a=0)
without supplying self
; self
is "bound" automatically when you have an instance of the class.
There is an important detail:
set PATH="C:\linutils;C:\wingit\bin;%PATH%"

ESLint 2.x experimentally supports ObjectRestSpread syntax, you can enable it by adding the following to your .eslintrc
: docs
"parserOptions": {
"ecmaVersion": 6,
"ecmaFeatures": {

}
},
ESLint 1.x doesn't natively support the spread operator, one way to get around this is using the babel-eslint parser. The latest installation and usage instructions are on the project readme.
For me, this one works well (thanks to the last comments for pointing out the directory /var/lib/docker/):
chroot /var/lib/docker/containers/2465790aa2c4*/root/
Here, 2465790aa2c4 is the short ID of the running container (as displayed by docker ps), followed by a star.
select @EmpID = ID from dbo.Employee
Or
set @EmpID =(select id from dbo.Employee)
Note that the select query might return more than one value or rows. so you can write a select query that must return one row.
If you would like to add more columns to one variable(MS SQL), there is an option to use table defined variable
DECLARE @sampleTable TABLE(column1 type1)
INSERT INTO @sampleTable
SELECT columnsNumberEqualInsampleTable FROM .. WHERE ..
As table type variable do not exist in Oracle and others, you would have to define it:
DECLARE TYPE type_name IS TABLE OF (column_type | variable%TYPE | table.column%TYPE [NOT NULL] INDEX BY BINARY INTEGER;
-- Then to declare a TABLE variable of this type: variable_name type_name;
-- Assigning values to a TABLE variable: variable_name(n).field_name := 'some text'
;
-- Where 'n' is the index value
But from what I understand xs:choice still only allows single element selection. Hence setting the MaxOccurs to unbounded like this should only mean that "any one" of the child elements can appear multiple times. Is this accurate?
No. The choice happens individually for every "repetition" of xs:choice
that occurs due to maxOccurs="unbounded"
. Therefore, the code that you have posted is correct, and will actually do what you want as written.
I know that this question is from a while ago, but I wanted to add an answer that I believe expands upon the original question. The addendum to this question was to write the mode method without relying upon a preset range (in this case, 0 through 100). I have written a version for mode that uses the range of values in the original array to generate the count array.
public static int mode(int[] list) {
//Initialize max and min value variable as first value of list
int maxValue = list[0];
int minValue = list[0];
//Finds maximum and minimum values in list
for (int i = 1; i < list.length; i++) {
if (list[i] > maxValue) {
maxValue = list[i];
}
if (list[i] < minValue) {
minValue = list[i];
}
}
//Initialize count array with (maxValue - minValue + 1) elements
int[] count = new int[maxValue - minValue + 1];
//Tally counts of values from list, store in array count
for (int i = 0; i < list.length; i++) {
count[list[i] - minValue]++; //Increment counter index for current value of list[i] - minValue
}
//Find max value in count array
int max = count[0]; //Initialize max variable as first value of count
for (int i = 1; i < count.length; i++) {
if (count[i] > max) {
max = count[i];
}
}
//Find first instance where max occurs in count array
for (int i = 0; i < count.length; i++) {
if (count[i] == max) {
return i + minValue; //Returns index of count adjusted for min/max list values - this is the mode value in list
}
}
return -1; //Only here to force compilation, never actually used
}
For me deleting the derived data fixed it , I noticed even if I check out from an old commit, the same issue happens.

It's fairly simple. You write values using keys and expiry times. You get values using keys. You can expire keys from the system.
Most clients follow the same rules. You can read the generic instructions and best practices on the memcached homepage.
If you really want to dig into it, I'd look at the source. Here's the header comment:
"""
client module for memcached (memory cache daemon)
Overview
========
See U{the MemCached homepage<http://www.danga.com/memcached>} for more about memcached.
Usage summary
=============
This should give you a feel for how this module operates::
import memcache
mc = memcache.Client(['127.0.0.1:11211'], debug=0)
mc.set("some_key", "Some value")
value = mc.get("some_key")
mc.set("another_key", 3)
mc.delete("another_key")
mc.set("key", "1") # note that the key used for incr/decr must be a string.
mc.incr("key")
mc.decr("key")
The standard way to use memcache with a database is like this::
key = derive_key(obj)
obj = mc.get(key)
if not obj:
obj = backend_api.get(...)
mc.set(key, obj)
# we now have obj, and future passes through this code
# will use the object from the cache.

var promiseGet = Directory_Service.getAllStaff(floor);
promiseGet.then(function (pl) {
$scope.staffList = chunk(pl.data, 3); //pl.data; //
},
function (errorOD) {
$log.error('Errored while getting staff list.', errorOD);
});
}
function chunk(array, columns) {
var numberOfRows = Math.ceil(array.length / columns);
//puts 1, 2, 3 into column
var newRow = []; //array is row-based.
for (var i = 0; i < array.length; i++) {
var columnData = new Array(columns);
if (i == numberOfRows) break;
for (j = 0; j < columns; j++)
{
columnData[j] = array[i + numberOfRows * j];
}
newRow.push(columnData);
}
return newRow;
////this works but 1, 2, 3 is in row
//var newRow = [];
//for (var i = 0; i < array.length; i += columns) {
// newRow.push(array.slice(i, i + columns)); //push effectively does the pivot. array is row-based.
//}
//return newRow;
};

I had a similar problem. As I got a Character from my XML child I had to convert it first to a String (or Integer, if you expect one). The following shows how I solved the problem.
foreach($xml->children() as $newInstr){
$iInstrument = new Instrument($newInstr['id'],$newInstr->Naam,$newInstr->Key);
$arrInstruments->offsetSet((String)$iInstrument->getID(), $iInstrument);
}
The regex way:
var matches = !!location.href.match(/franky/); //a boolean value now
Or in a simple statement you could use:
if (location.href.match(/franky/)) {
I use this to test whether the website is running locally or on a server:
location.href.match(/(192.168|localhost).*:1337/)
This checks whether the href contains either 192.168
or localhost
AND is followed by :1337
.
As you can see, using regex has its advantages over the other solutions when the condition gets a bit trickier.
You can use the ParseExact() method to obtain a DateTime object. You can then use the ToString() method of that DateTime object to convert the string to what ever you need as shown here.
Bootstrap. Check out their awesome grid system here.
Using Bootstrap, you could make three columns like this:
<div class="container">
<div class="row">
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>
<div class="col-md-4">.col-md-4</div>

When maven is working outside of Eclipse, but giving this error after a JDK change, Go to your Maven Run Configuration, and at the bottom of the Main page, there's a 'Maven Runtime' option. Mine was using the Embedded Maven, so after switching it to use my external maven, it worked.
I would suggest using the following technique:
struct HexCharStruct
{
unsigned char c;
HexCharStruct(unsigned char _c) : c(_c) { }
};
inline std::ostream& operator<<(std::ostream& o, const HexCharStruct& hs)
{
return (o << std::hex << (int)hs.c);
}
inline HexCharStruct hex(unsigned char _c)
{
return HexCharStruct(_c);
}
int main()
{
char a = 131;
std::cout << hex(a) << std::endl;
}
It's short to write, has the same efficiency as the original solution and it lets you choose to use the "original" character output. And it's type-safe (not using "evil" macros :-))
This worked for me. :)

I use the \!
command within MySQL to grep out NULL values from the shell:
\! mysql -e "SELECT * FROM table WHERE column = 123456\G" | grep -v NULL
It works best with a proper .my.cnf
where your database/username/password are specified. That way you just have to surround your select
with \! mysql e
and | grep -v NULL
.
io.sockets.sockets[socket.id].emit(...) worked for me in v0.9
Why
There is IMHO a good reason why Composer will use the --dev
flag by default (on install and update) nowadays. Composer is mostly run in scenario's where this is desired behavior:
The basic Composer workflow is as follows:
composer.phar install --dev
, json and lock files are commited to VCS.composer.phar install --dev
.composer.phar require <package>
, add --dev
if you want the package in the require-dev
section (and commit).composer.phar install --dev
.composer.phar update --dev <package>
(and commit).composer.phar install --dev
.composer.phar install --no-dev
As you can see the --dev
flag is used (far) more than the --no-dev
flag, especially when the number of developers working on the project grows.
Production deploy
What's the correct way to deploy this without installing the "dev" dependencies?
Well, the composer.json
and composer.lock
file should be committed to VCS. Don't omit composer.lock
because it contains important information on package-versions that should be used.
When performing a production deploy, you can pass the --no-dev
flag to Composer:
composer.phar install --no-dev
The composer.lock
file might contain information about dev-packages. This doesn't matter. The --no-dev
flag will make sure those dev-packages are not installed.
When I say "production deploy", I mean a deploy that's aimed at being used in production. I'm not arguing whether a composer.phar install
should be done on a production server, or on a staging server where things can be reviewed. That is not the scope of this answer. I'm merely pointing out how to composer.phar install
without installing "dev" dependencies.
Offtopic
The --optimize-autoloader
flag might also be desirable on production (it generates a class-map which will speed up autoloading in your application):
composer.phar install --no-dev --optimize-autoloader
Or when automated deployment is done:
composer.phar install --no-ansi --no-dev --no-interaction --no-plugins --no-progress --no-scripts --optimize-autoloader
If your codebase supports it, you could swap out --optimize-autoloader
for --classmap-authoritative
. More info here

Python really tries hard to intelligently set sys.path
. How it is
set can get really complicated. The following guide is a watered-down,
somewhat-incomplete, somewhat-wrong, but hopefully-useful guide
for the rank-and-file python programmer of what happens when python
figures out what to use as the initial values of sys.path
,
sys.executable
, sys.exec_prefix
, and sys.prefix
on a normal
python installation.
First, python does its level best to figure out its actual physical
location on the filesystem based on what the operating system tells
it. If the OS just says "python" is running, it finds itself in $PATH.
It resolves any symbolic links. Once it has done this, the path of
the executable that it finds is used as the value for sys.executable
, no ifs,
ands, or buts.
Next, it determines the initial values for sys.exec_prefix
and
sys.prefix
.
If there is a file called pyvenv.cfg
in the same directory as
sys.executable
or one directory up, python looks at it. Different
OSes do different things with this file.
One of the values in this config file that python looks for is
the configuration option home = <DIRECTORY>
. Python will use this directory instead of the directory containing sys.executable
when it dynamically sets the initial value of sys.prefix
later. If the applocal = true
setting appears in the
pyvenv.cfg
file on Windows, but not the home = <DIRECTORY>
setting,
then sys.prefix
will be set to the directory containing sys.executable
.
Next, the PYTHONHOME
environment variable is examined. On Linux and Mac,
sys.prefix
and sys.exec_prefix
are set to the PYTHONHOME
environment variable, if
it exists, superseding any home = <DIRECTORY>
setting in pyvenv.cfg
. On Windows,
sys.prefix
and sys.exec_prefix
is set to the PYTHONHOME
environment variable,
if it exists, unless a home = <DIRECTORY>
setting is present in pyvenv.cfg
,
which is used instead.
Otherwise, these sys.prefix
and sys.exec_prefix
are found by walking backwards
from the location of sys.executable
, or the home
directory given by pyvenv.cfg
if any.
If the file lib/python<version>/dyn-load
is found in that directory
or any of its parent directories, that directory is set to be to be
sys.exec_prefix
on Linux or Mac. If the file
lib/python<version>/os.py
is is found in the directory or any of its
subdirectories, that directory is set to be sys.prefix
on Linux,
Mac, and Windows, with sys.exec_prefix
set to the same value as
sys.prefix
on Windows. This entire step is skipped on Windows if
applocal = true
is set. Either the directory of sys.executable
is
used or, if home
is set in pyvenv.cfg
, that is used instead for
the initial value of sys.prefix
.
If it can't find these "landmark" files or sys.prefix
hasn't been
found yet, then python sets sys.prefix
to a "fallback"
value. Linux and Mac, for example, use pre-compiled defaults as the
values of sys.prefix
and sys.exec_prefix
. Windows waits
until sys.path
is fully figured out to set a fallback value for
sys.prefix
.
Then, (what you've all been waiting for,) python determines the initial values
that are to be contained in sys.path
.
sys.path
.
On Windows, this is always the empty string, which tells python to
use the full path where the script is located instead.sys.path
, unless you're
on Windows and applocal
is set to true in pyvenv.cfg
.<prefix>/lib/python35.zip
on Linux/Mac and
os.path.join(os.dirname(sys.executable), "python.zip")
on Windows, is added to sys.path
.applocal = true
was set in pyvenv.cfg
, then the contents of the subkeys of the registry key
HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\
are added, if any.applocal = true
was set in pyvenv.cfg
, and sys.prefix
could not be found,
then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\
is added, if it exists;applocal = true
was set in pyvenv.cfg
, then the contents of the subkeys of the registry key
HK_LOCAL_MACHINE\Software\Python\PythonCore\<DLLVersion>\PythonPath\
are added, if any.applocal = true
was set in pyvenv.cfg
, and sys.prefix
could not be found,
then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\
is added, if it exists;sys.prefix
.sys.exec_prefix
is added. On Windows, the directory
which was used (or would have been used) to search dynamically for sys.prefix
is
added.At this stage on Windows, if no prefix was found, then python will try to
determine it by searching all the directories in sys.path
for the landmark files,
as it tried to do with the directory of sys.executable
previously, until it finds something.
If it doesn't, sys.prefix
is left blank.
Finally, after all this, Python loads the site
module, which adds stuff yet further to sys.path
:
It starts by constructing up to four directories from a head and a tail part. For the head part, it uses
sys.prefix
andsys.exec_prefix
; empty heads are skipped. For the tail part, it uses the empty string and thenlib/site-packages
(on Windows) orlib/pythonX.Y/site-packages
and thenlib/site-python
(on Unix and Macintosh). For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files.
To receive arbitrary Json in Spring-Boot, you can simply use Jackson's JsonNode
. The appropriate converter is automatically configured.

}
Even though this solution might seem obvious, I just wanted to post it here so the next guy will google it faster.
If you still want to have the model as a parameter in the method, you can create a DelegatingHandler
to buffer the content.
internal sealed class BufferizingHandler : DelegatingHandler
{
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
await request.Content.LoadIntoBufferAsync();
var result = await base.SendAsync(request, cancellationToken);
return result;
}
}
And add it to the global message handlers:
configuration.MessageHandlers.Add(new BufferizingHandler());
This solution is based on the answer by Darrel Miller.
This way all the requests will be buffered.
you can use wc to count the number of characters in the file wc -m filename.txt. Hope that help.
Powder's comment may go undetected like I missed it so many times,. So with the hope of making it more visible, I will re-iterate his point.
Sometimes using image = array(img).reshape(a,b,c,d)
will reshape alright but from experience, my kernel crashes every time I try to use the new dimension in an operation. The safest to use is
np.expand_dims(img, axis=0)
It works perfect every time. I just can't explain why. This link has a great explanation and examples regarding its usage.
If you don't have privileges to create a view in Oracle, a "hack" around it to use MS Access :-(
In MS Access, create a pass through query with your sql (but add where clause to just select 1 record), create a select query from the view (very important), selecting all *, then create a make table from the select query. When this runs it will create a table with one record, all the data types should "match" oracle. i.e. Passthrough --> Select --> MakeTable --> Table
I am sure there are other better ways, but if you have limited tools and privileges this will work.
For me when I created a file and saved it as python file, I was getting this error during importing. I had to create a filename with the type ".py" , like filename.py and then save it as a python file. post trying to import the file worked for me.

There are some tips regarding VBA programming that might help you out.
Use always explicit references to the sheet you want to interact with. Otherwise, Excel may 'assume' your code applies to the active sheet and eventually you'll see it screws your spreadsheet up.
As lionz mentioned, get in touch with the native methods Excel offers. You might use them on most of your tricks.
Explicitly declare your variables... they'll show the list of methods each object offers in VBA. It might save your time digging on the internet.
Now, let's have a draft code...
Remember this code must be within the Excel Sheet object, as explained by lionz. It only applies to Sheet 2, is up to you to adapt it to both Sheet 2 and Sheet 3 in the way you prefer.
Hope it helps!
Private Sub Worksheet_Change(ByVal Target As Range)
Dim oSheet As Excel.Worksheet
'We only want to do something if the changed cell is B6, right?
If Target.Address = "$B$6" Then
'Checks if it's a number...
If IsNumeric(Target.Value) Then
'Let's avoid values out of your bonds, correct?
If Target.Value > 0 And Target.Value < 51 Then
'Let's assign the worksheet we'll show / hide rows to one variable and then
' use only the reference to the variable itself instead of the sheet name.
' It's safer.
'You can alternatively replace 'sheet 2' by 2 (without quotes) which will represent
' the sheet index within the workbook
Set oSheet = ActiveWorkbook.Sheets("Sheet 2")
'We'll unhide before hide, to ensure we hide the correct ones
oSheet.Range("A7:A56").EntireRow.Hidden = False
oSheet.Range("A" & Target.Value + 7 & ":A56").EntireRow.Hidden = True
End If
End If
End If
End Sub
Alternative solution using generic algorithms and Boost.Tokenizer:
struct ToInt
{
int operator()(string const &str) { return atoi(str.c_str()); }
};
string values = "1,2,3,4,5,9,8,7,6";
vector<int> ints;
tokenizer<> tok(values);
transform(tok.begin(), tok.end(), back_inserter(ints), ToInt());
First of all don't use 'list' as variable name.
If you have simple dictionaries with unique keys then you can do the following(note that new dictionary object with all items from sub-dictionaries will be created):
res = {}
for line in listOfDicts:
res.update(line)
res['d']
>>> 4
Otherwise:
getValues = lambda key,inputData: [subVal[key] for subVal in inputData if key in subVal]
getValues('d', listOfDicts)
>>> [4]
Or very base:
def get_value(listOfDicts, key):
for subVal in listOfDicts:
if key in subVal:
return subVal[key]
1 byte may hold 1 character. For Example: Refer Ascii values for each character & convert into binary. This is how it works.
value 255 is stored as (11111111) base 2. Visit this link for knowing more about binary conversion. http://acc6.its.brooklyn.cuny.edu/~gurwitz/core5/nav2tool.html
Size of Tiny Int = 1 Byte ( -128 to 127)
Int = 4 Bytes (-2147483648 to 2147483647)
In openCV whenever you try to display an oversized image or image bigger than your display resolution you get the cropped display. It's a default behaviour.
In order to view the image in the window of your choice openCV encourages to use named window. Please refer to namedWindow documentation
The function namedWindow creates a window that can be used as a placeholder for images and trackbars. Created windows are referred to by their names.
cv.namedWindow(name, flags=CV_WINDOW_AUTOSIZE)
where each window is related to image container by the name arg, make sure to use same name
eg:
import cv2
frame = cv2.imread('1.jpg')
cv2.namedWindow("Display 1")
cv2.resizeWindow("Display 1", 300, 300)
cv2.imshow("Display 1", frame)
I just want to add that there is another Lifecycle hook called DoCheck
that is useful if the @Input
value is not a primitive value.
I have an Array as an Input
so this does not fire the OnChanges
event when the content changes (because the checking that Angular does is 'simple' and not deep so the Array is still an Array, even though the content on the Array has changed).
I then implement some custom checking code to decide if I want to update my view with the changed Array.
A simple way to do that in VBA is:
YourText = "c:\excel\text.txt"
xString = Mid(YourText, 2 + Len(YourText) - InStr(StrReverse(YourText), "\" ))
Probably this is not best code for this task, but is working -
def front_back(a, b):
if len(a) % 2 == 0 and len(b) % 2 == 0:
print a[:(len(a)/2)] + b[:(len(b)/2)] + a[(len(a)/2):] + b[(len(b)/2):]
elif len(a) % 2 == 1 and len(b) % 2 == 0:
print a[:(len(a)/2)+1] + b[:(len(b)/2)] + a[(len(a)/2)+1:] + b[(len(b)/2):]
elif len(a) % 2 == 0 and len(b) % 2 == 1:
print a[:(len(a)/2)] + b[:(len(b)/2)+1] + a[(len(a)/2):] + b[(len(b)/2)+1:]
else :
print a[:(len(a)/2)+1] + b[:(len(b)/2)+1] + a[(len(a)/2)+1:] + b[(len(b)/2)+1:]
you can use
- (void)highlightLetter:(UITapGestureRecognizer*)sender {
UIView *view = sender.view;
NSLog(@"%d", view.tag);
}
view will be the Object in which the tap gesture was recognised
As has been mentioned, slicing with None
or with np.newaxes
is a great way to do this.
Another alternative is to use transposes and broadcasting, as in
(data.T - vector).T
and
(data.T / vector).T
For higher dimensional arrays you may want to use the swapaxes
method of NumPy arrays or the NumPy rollaxis
function.
There really are a lot of ways to do this.
For a fuller explanation of broadcasting, see http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html
You can access your keys and/or values by calling items() on your dictionary.

You need to do a LEFT JOIN
.
SELECT Computer.ComputerName, Application.Name, Software.Version
FROM Computer
JOIN dbo.Software_Computer
ON Computer.ID = Software_Computer.ComputerID
LEFT JOIN dbo.Software
ON Software_Computer.SoftwareID = Software.ID
RIGHT JOIN dbo.Application
ON Application.ID = Software.ApplicationID
WHERE Computer.ID = 1
Here is the explanation:
The result of a left outer join (or simply left join) for table A and B always contains all records of the "left" table (A), even if the join-condition does not find any matching record in the "right" table (B). This means that if the ON clause matches 0 (zero) records in B, the join will still return a row in the result—but with NULL in each column from B. This means that a left outer join returns all the values from the left table, plus matched values from the right table (or NULL in case of no matching join predicate). If the right table returns one row and the left table returns more than one matching row for it, the values in the right table will be repeated for each distinct row on the left table. From Oracle 9i onwards the LEFT OUTER JOIN statement can be used as well as (+).

Let's assume this is your class:
class Test
{
private $baz = 1;
public function foo() { ... }
public function bar()
{
printf("baz = %d\n", $this->baz);
}
public static function staticMethod() { echo "static method\n"; }
}
From within the foo()
method, let's look at the different options:
$this->staticMethod();
So that calls staticMethod()
as an instance method, right? It does not. This is because the method is declared as public static
the interpreter will call it as a static method, so it will work as expected. It could be argued that doing so makes it less obvious from the code that a static method call is taking place.
$this::staticMethod();
Since PHP 5.3 you can use $var::method()
to mean <class-of-$var>::
; this is quite convenient, though the above use-case is still quite unconventional. So that brings us to the most common way of calling a static method:
self::staticMethod();
Now, before you start thinking that the ::
is the static call operator, let me give you another example:
self::bar();
This will print baz = 1
, which means that $this->bar()
and self::bar()
do exactly the same thing; that's because ::
is just a scope resolution operator. It's there to make parent::
, self::
and static::
work and give you access to static variables; how a method is called depends on its signature and how the caller was called.
To see all of this in action, see this 3v4l.org output.
you can do it like this
$.when(funtion1()).then(function(){
funtion2();
})
You have to bind your event handlers to correct context (this
):
onChange={this.setAuthorState.bind(this)}
Not sure if this was what you were asking for, but I was personally trying to 'hide' some info in my html so that if someone inspected it, they would see the text in the source code.
It turns out that you can add ANY attribute, and so long as it isn't understood by the browser, it will just be left buried in the tag. My code was an easter egg: For people who couldn't afford to do the Makers Academy course, I basically encouraged them to inspect the element, where they would be given a secret URL where they could apply for a special, cut-price course (it's in haml, but it's the same idea in HTML):
.entry
%h2 I can't afford to do the course... What should I do?
%p{:url_you_should_visit => 'http://ronin.makersacademy.com'} Inspect and you shall find.
Or in html:
<p url_you_should_visit="http://ronin.makersacademy.com">Inspect and you shall find.</p>
Because 'url' is not a recognised html attribute, it makes no difference but is still discoverable. You could do the same with anything you wanted. You could have an attribute (in html) like:
<p thanks="Thanks to all the bloggers that helped me"> Some text </p>
And they'll be able to find your little easter egg if they want it... Hope that helps - it certainly helped me :)
For me it was the "Start In" - I accidentally left in the '.py' at the end of the name of my program. And I forgot to capitalize the name of the folder it was in ('Apps').
Hello i was have the same issue, but it is easly, just do this:
string cadena="96.23";
decimal NoDecimal=decimal.parse(cadena.replace(".",","))
I think this is beacuse the notation that accept C# on decimal numbers are with a ","

Python (like almost every programming language today) supports structured programming which controls flow using if/then/else, loop and subroutines.
The key to thinking in a structured way is to understand how and why you are branching on code.
For example, lets pretend Python had a goto
and corresponding label
statement shudder. Look at the following code. In it if a number is greater than or equal to 0 we print if it
number = input()
if number < 0: goto negative
if number % 2 == 0:
print "even"
else:
print "odd"
goto end
label: negative
print "negative"
label: end
print "all done"
If we want to know when a piece of code is executed, we need to carefully traceback in the program, and examine how a label was arrived at - which is something that can't really be done.
For example, we can rewrite the above as:
number = input()
goto check
label: negative
print "negative"
goto end
label: check
if number < 0: goto negative
if number % 2 == 0:
print "even"
else:
print "odd"
goto end
label: end
print "all done"
Here, there are two possible ways to arrive at the "end", and we can't know which one was chosen. As programs get large this kind of problem gets worse and results in spaghetti code
In comparison, below is how you would write this program in Python:
number = input()
if number >= 0:
if number % 2 == 0:
print "even"
else:
print "odd"
else:
print "negative"
print "all done"
I can look at a particular line of code, and know under what conditions it is met by tracing back the tree of if/then/else
blocks it is in. For example, I know that the line print "odd"
will be run when a ((number >= 0) == True) and ((number % 2 == 0) == False)
.
Before anyone spends to much time debugging this problem, most of the time it can be resolved by deleting node_modules
and reinstalling the packages.
If a lockfile exists you might use
yarn install --frozen-lockfile
or
npm ci
respectivly. if not then
yarn install
or
npm i

I recommend installing the custom_error_message gem (or as a plugin) originally written by David Easley
It lets you do stuff like:
validates_presence_of :non_friendly_field_name, :message => "^Friendly field name is blank"
I can't believe how many times this question has been answered without understanding and/or addressing the problem with the Original Poster's actual code. That said, I'm a beginner myself (only 2 months of coding). My code does work perfectly, but feel free to suggest any changes to it. Here's the solution:
//include the 'async':false parameter or the object data won't get captured when loading
var json = $.getJSON({'url': "http://spoonertuner.com/projects/test/test.json", 'async': false});
//The next line of code will filter out all the unwanted data from the object.
json = JSON.parse(json.responseText);
//You can now access the json variable's object data like this json.a and json.c
document.write(json.a);
console.log(json);
Here's a shorter way of writing the same code I provided above:
var json = JSON.parse($.getJSON({'url': "http://spoonertuner.com/projects/test/test.json", 'async': false}).responseText);
You can also use $.ajax instead of $.getJSON to write the code exactly the same way:
var json = JSON.parse($.ajax({'url': "http://spoonertuner.com/projects/test/test.json", 'async': false}).responseText);
Finally, the last way to do this is to wrap $.ajax in a function. I can't take credit for this one, but I did modify it a bit. I tested it and it works and produces the same results as my code above. I found this solution here --> load json into variable
var json = function () {
var jsonTemp = null;
$.ajax({
'async': false,
'url': "http://spoonertuner.com/projects/test/test.json",
'success': function (data) {
jsonTemp = data;
}
});
return jsonTemp;
}();
document.write(json.a);
console.log(json);
The test.json file you see in my code above is hosted on my server and contains the same json data object that he (the original poster) had posted.
{
"a" : "b",
"c" : "d"
}
There's no benefit to using properties with primitive types. @property
is used with heap allocated NSObjects
like NSString*
, NSNumber*
, UIButton*
, and etc, because memory managed accessors are created for free. When you create a BOOL
, the value is always allocated on the stack and does not require any special accessors to prevent memory leakage. isWorking
is simply the popular way of expressing the state of a boolean value.
In another OO language you would make a variable private bool working;
and two accessors: SetWorking
for the setter and IsWorking
for the accessor.
There are two ways to disable ActionBar
in Android.
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
The extensions methods also provide a ToDictionary extension. It is fairly simple to use, the general usage is passing a lambda selector for the key and getting the object as the value, but you can pass a lambda selector for both key and value.
class SomeObject
{
public int ID { get; set; }
public string Name { get; set; }
}
SomeObject[] objects = new SomeObject[]
{
new SomeObject { ID = 1, Name = "Hello" },
new SomeObject { ID = 2, Name = "World" }
};
Dictionary<int, string> objectDictionary = objects.ToDictionary(o => o.ID, o => o.Name);
Then objectDictionary[1]
Would contain the value "Hello"
I suggest you replace the deprecated apache HttpClient with the new HttpURLConnection.
That's a cleaner solution, it's quite easy to migrate, and generally it's better to stick to the latest SDK changes than trying to hack/patch/workaround: you usually regret it later :)
Step 1
HttpGet httpGet = new HttpGet(url);
becomes:
URL urlObj = new URL(url);
Step 2
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpResponse response = httpClient.execute(httpGet, localContext);
InputStream is = response.getEntity().getContent();
becomes:
HttpURLConnection urlConnection = (HttpURLConnection) urlObj.openConnection();
InputStream is = urlConnection.getInputStream();
Step 2 bis
int status = response.getStatusLine().getStatusCode();
becomes:
int status = urlConnection.getResponseCode();
Maybe something changed but this gave back a list of ndarrays which did what I needed.
list(df.values)
select persons.personsid,name,info.id,address
-> from persons
-> inner join persons on info.infoid = info.info.id;
You need to wrap your form processing code in a conditional so it doesn't run when you first open the page. Something like so:
if($_POST['num1'] > 0 && $_POST['num2'] > 0 && $_POST['num3'] > 0 && $_POST['num4'] > 0){
$itemQty = $_POST['num1'];
$itemCost = $_POST['num2'];
$itemSale = $_POST['num3'];
$shipMat = $_POST['num4'];
$diffPrice = $itemSale - $itemCost;
$actual = ($diffPrice - $shipMat) * $itemQty;
$diffPricePercent = (($actual * 100) / $itemCost) / $itemQty ;
}
In case you need to parse it from a file, I find the best solution to use a HashMap<String, String>
to use it inside your java code for better manipultion.
Try out this code:
public HashMap<String, String> myMethodName() throws FileNotFoundException
{
String path = "absolute path to your file";
BufferedReader bufferedReader = new BufferedReader(new FileReader(path));
Gson gson = new Gson();
HashMap<String, String> json = gson.fromJson(bufferedReader, HashMap.class);
return json;
}
Anytime you have a question about a particular function in PHP, the easiest way to get quick answers is by visiting php.net, which has great documentation on all of the language's capabilities.
Looking up a function is easy, just visit http://php.net/<function name>
and it will forward you to the appropriate place. For the date function, we'll visit http://php.net/date.
We immediately learn a couple things about this function by examining its signature:
string date ( string $format [, int $timestamp = time() ] )
First, it returns a string. That's what the first string
in the above code means. Secondly, the first parameter is expected to be a string containing the format. There is an optional second parameter for passing in your own timestamp (to construct strings from some time other than now).
date("d-m-Y") // produces something like 03-12-2012
In this code, d
represents the day of the month (with a leading 0 is necessary). m
represents the month, again with a leading zero if necessary. And Y
represents the full 4-digit year. All of these are documented in the aforementioned link.
To satisfy your request of getting the hours, minutes, and seconds, we need to give a quick look at the documentation to see which characters represents those particular units of time. When we do that, we find the following:
h 12-hour format of an hour with leading zeros 01 through 12
i Minutes with leading zeros 00 to 59
s Seconds, with leading zeros 00 through 59
With this in mind, we can no create a new format string:
date("d-m-Y h:i:s"); // produces something like 03-12-2012 03:29:13
Hope this is helpful, and I hope you find the documentation has benefiting to your development as I have to mine.
I use these:
.right {display:table; margin:-18px 0 0 auto;}
.center {display:table; margin:-18px auto 0 auto;}
Using an element-wise logical or and setting the take_last argument of the pandas duplicated method to both True and False you can obtain a set from your dataframe that includes all of the duplicates.
df_bigdata_duplicates =
df_bigdata[df_bigdata.duplicated(cols='ID', take_last=False) |
df_bigdata.duplicated(cols='ID', take_last=True)
]
Definitely it's blocking because of your use of urllib based on the user agent. This same thing is happening to me with OfferUp. You can create a new class called AppURLopener which overrides the user-agent with Mozilla.
import urllib.request
class AppURLopener(urllib.request.FancyURLopener):
version = "Mozilla/5.0"
opener = AppURLopener()
response = opener.open('http://httpbin.org/user-agent')
You can mock out aw.Clear
, either manually or using a testing framework like pymox. Manually, you'd do it using something like this:
class MyTest(TestCase):
def testClear():
old_clear = aw.Clear
clear_calls = 0
aw.Clear = lambda: clear_calls += 1
aps.Request('nv2', aw)
assert clear_calls == 1
aw.Clear = old_clear
Using pymox, you'd do it like this:
class MyTest(mox.MoxTestBase):
def testClear():
aw = self.m.CreateMock(aps.Request)
aw.Clear()
self.mox.ReplayAll()
aps.Request('nv2', aw)
//paste required image on C disk
JButton button = new JButton(new ImageIcon("C:water.bmp");
The accepted answer is correct but it doesn't tell you how to use it. This is how you use indexOf and substring functions together.
String filename = "abc.def.ghi"; // full file name
int iend = filename.indexOf("."); //this finds the first occurrence of "."
//in string thus giving you the index of where it is in the string
// Now iend can be -1, if lets say the string had no "." at all in it i.e. no "." is found.
//So check and account for it.
String subString;
if (iend != -1)
{
subString= filename.substring(0 , iend); //this will give abc
}
return=[entry for tag in tags for entry in entries if tag in entry for entry in entry]
You have to execute your query and add single quote to $email in the query beacuse it's a string, and remove the is_resource($query)
$query is a string, the $result will be the resource
$query = "SELECT `email` FROM `tblUser` WHERE `email` = '$email'";
$result = mysqli_query($link,$query); //$link is the connection
if(mysqli_num_rows($result) > 0 ){....}
UPDATE
Base in your edit just change:
if(is_resource($query) && mysqli_num_rows($query) > 0 ){
$query = mysqli_fetch_assoc($query);
echo $email . " email exists " . $query["email"] . "\n";
By
if(is_resource($result) && mysqli_num_rows($result) == 1 ){
$row = mysqli_fetch_assoc($result);
echo $email . " email exists " . $row["email"] . "\n";
and you will be fine
UPDATE 2
A better way should be have a Store Procedure that execute the following SQL passing the Email as Parameter
SELECT IF( EXISTS (
SELECT *
FROM `Table`
WHERE `email` = @Email)
, 1, 0) as `Exist`
and retrieve the value in php
Pseudocodigo:
$query = Call MYSQL_SP($EMAIL);
$result = mysqli_query($conn,$query);
$row = mysqli_fetch_array($result)
$exist = ($row['Exist']==1)? 'the email exist' : 'the email doesnt exist';
The easiest way is probably just to split on your target word
my_string="hello python world , i'm a beginner "
print my_string.split("world",1)[1]
split takes the word(or character) to split on and optionally a limit to the number of splits.
In this example split on "world" and limit it to only one split.
If you go the href route, you can save it
To disable:
$('a').each(function(){
$(this).data("href", $(this).attr("href")).removeAttr("href");
});
Then re-enable using:
$('a').each(function(){
$(this).attr("href", $(this).data("href"));
});
In one case I had to do it this way because the click events were already bound somewhere else and I had no control over it.
The environment variables of a process exist at runtime, and are not stored in some file or so. They are stored in the process's own memory (that's where they are found to pass on to children). But there is a virtual file in
/proc/pid/environ
This file shows all the environment variables that were passed when calling the process (unless the process overwrote that part of its memory — most programs don't). The kernel makes them visible through that virtual file. One can list them. For example to view the variables of process 3940, one can do
cat /proc/3940/environ | tr '\0' '\n'
Each variable is delimited by a binary zero from the next one. tr replaces the zero into a newline.
Here is my solution:
<!-- jquery smooth scroll to id's -->
<script>
$(function() {
$('a[href*=\\#]:not([href=\\#])').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top
}, 500);
return false;
}
}
});
});
</script>
With just this snippet you can use an unlimited number of hash-links and corresponding ids without having to execute a new script for each.
I already explained how it works in another thread here: https://stackoverflow.com/a/28631803/4566435 (or here's a direct link to my blog post)
For clarifications, let me know. Hope it helps!
As has been mentioned by others, if you don't assign the result of explode()
to a variable, you get the message:
E_STRICT: Strict standards: Only variables should be passed by reference
The correct way is:
$words = explode('-', 'hello-world-123');
$id = array_pop($words); // 123
$slug = implode('-', $words); // hello-world
You can use argv[0] and analyze the PATH environment variable. Look at : A sample of a program that can find itself
Even better use implicit remoting to use a module from another Machine!
$s = New-PSSession Server-Name
Invoke-Command -Session $s -ScriptBlock {Import-Module ActiveDirectory}
Import-PSSession -Session $s -Module ActiveDirectory -Prefix REM
This will allow you to use the module off a remote PC for as long as the PSSession is connected.

As mentioned above, you can change the property of the textbox "Read Only" to "True" from the properties window.
The most common valid reason for wanting an integer constant associated with each enum value is to interoperate with some other component which still expects those integers (e.g. a serialization protocol which you can't change, or the enums represent columns in a table, etc).
In almost all cases I suggest using an EnumMap
instead. It decouples the components more completely, if that was the concern, or if the enums represent column indices or something similar, you can easily make changes later on (or even at runtime if need be).
private final EnumMap<Page, Integer> pageIndexes = new EnumMap<Page, Integer>(Page.class);
pageIndexes.put(Page.SIGN_CREATE, 1);
//etc., ...
int createIndex = pageIndexes.get(Page.SIGN_CREATE);
It's typically incredibly efficient, too.
Adding data like this to the enum instance itself can be very powerful, but is more often than not abused.
Edit: Just realized Bloch addressed this in Effective Java / 2nd edition, in Item 33: Use EnumMap
instead of ordinal indexing.
I managed to figure it out in the end, so if anyone is looking for the answer:
//Firefox
$('#elem').bind('DOMMouseScroll', function(e){
if(e.originalEvent.detail > 0) {
//scroll down
console.log('Down');
}else {
//scroll up
console.log('Up');
}
//prevent page fom scrolling
return false;
});
//IE, Opera, Safari
$('#elem').bind('mousewheel', function(e){
if(e.originalEvent.wheelDelta < 0) {
//scroll down
console.log('Down');
}else {
//scroll up
console.log('Up');
}
//prevent page fom scrolling
return false;
});
This works for me (code called from node js repl):
const axios = require("axios");
axios
.put(
"http://localhost:4000/api/token",
"mytoken",
{headers: {"Content-Type": "text/plain"}}
)
.then(r => console.log(r.status))
.catch(e => console.log(e));
Logs: 200
And this is my request handler (I am using restify):
function handleToken(req, res) {
if(typeof req.body === "string" && req.body.length > 3) {
res.send(200);
} else {
res.send(400);
}
}
Content-Type header is important here.
Edit (2017-10-12):
@MechaLynx and @Kevin-Weber note that unescape()
is deprecated from non-browser environments and does not exist in TypeScript. decodeURIComponent
is a drop-in replacement. For broader compatibility, use the below instead:
decodeURIComponent(JSON.parse('"http\\u00253A\\u00252F\\u00252Fexample.com"'));
> 'http://example.com'
Original answer:
unescape(JSON.parse('"http\\u00253A\\u00252F\\u00252Fexample.com"'));
> 'http://example.com'
You can offload all the work to JSON.parse
Made a tiny program that accomplishes that:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
char str[8192] = "string"; // string
size_t len = strlen(str)-1; // get string length and reduce 1
while(len+1 > 0) // Loop for every character on string
{
printf("%c",str[len--]); // Print string reversed and reducing len by one
}
return 0; // Quit program
}
Explanation:
We take the length of the string, and then we start looping by the last position until we arrive to index 0 quit program.
Another way of doing it, without 3rd party programs nor converters ("batch to exe" programs actually just put your batch file in the tmp folder and then run it silently so anyone can just fetch it from there an get your code) no vbs files (because nobody knows vbs) just one line at the beginning of the batch file.

Yes. you can use SimpleDateFormat like this.
SimpleDateFormat formatter, FORMATTER;
formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
String oldDate = "2011-03-10T11:54:30.207Z";
Date date = formatter.parse(oldDate.substring(0, 24));
FORMATTER = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss.SSS");
System.out.println("OldDate-->"+oldDate);
System.out.println("NewDate-->"+FORMATTER.format(date));
Output OldDate-->2011-03-10T11:54:30.207Z NewDate-->10-Mar-2011 11:54:30.207
Absolutely Asset Catalog is you answer, it removes the need to follow naming conventions when you are adding or updating your app icons.
Below are the steps to Migrating an App Icon Set or Launch Image Set From Apple:
1- In the project navigator, select your target.
2- Select the General pane, and scroll to the App Icons section.
3- Specify an image in the App Icon table by clicking the folder icon on the right side of the image row and selecting the image file in the dialog that appears.
4-Migrate the images in the App Icon table to an asset catalog by clicking the Use Asset Catalog button, selecting an asset catalog from the popup menu, and clicking the Migrate button.
Alternatively, you can create an empty app icon set by choosing Editor > New App Icon, and add images to the set by dragging them from the Finder or by choosing Editor > Import.
For Ubuntu it works for following commands; If you want individual files to contain main method to run the files individually, may be for testing purpose,
pyuic5 filename.ui -o filename.py -x
No main method in file, cannot run individually... try
pyuic5 filename.ui -o filename.py
Consider, I'm using PyQT5.

From the Help:
IsEmpty returns True if the variable is uninitialized, or is explicitly set to Empty; otherwise, it returns False. False is always returned if expression contains more than one variable.
IsEmpty only returns meaningful information for variants.
To check if a cell is empty, you can use cell(x,y) = ""

You might eventually save time by using Range("X:Y").SpecialCells(xlCellTypeBlanks)

The trick is to read the declaration backwards (right-to-left):
const int a = 1; // read as "a is an integer which is constant"
int const a = 1; // read as "a is a constant integer"
Both are the same thing. Therefore:
a = 2; // Can't do because a is constant
The reading backwards trick especially comes in handy when you're dealing with more complex declarations such as:
const char *s; // read as "s is a pointer to a char that is constant"
char c;
char *const t = &c; // read as "t is a constant pointer to a char"
*s = 'A'; // Can't do because the char is constant
s++; // Can do because the pointer isn't constant
*t = 'A'; // Can do because the char isn't constant
t++; // Can't do because the pointer is constant

DIRECTORY
Default: DATA_PUMP_DIR
Purpose
Specifies the default location in which the import job can find the dump file set and where it should create log and SQL files.
Syntax and Description
DIRECTORY=directory_object
The directory_object is the name of a database directory object (not the file path of an actual directory). Upon installation, privileged users have access to a default directory object named DATA_PUMP_DIR. Users with access to the default DATA_PUMP_DIR directory object do not need to use the DIRECTORY parameter at all.
A directory object specified on the DUMPFILE, LOGFILE, or SQLFILE parameter overrides any directory object that you specify for the DIRECTORY parameter. You must have Read access to the directory used for the dump file set and Write access to the directory used to create the log and SQL files.
Example
The following is an example of using the DIRECTORY parameter. You can create the expfull.dmp dump file used in this example by running the example provided for the Export FULL parameter. See "FULL".
> impdp hr DIRECTORY=dpump_dir1 DUMPFILE=expfull.dmp
LOGFILE=dpump_dir2:expfull.log
This command results in the import job looking for the expfull.dmp dump file in the directory pointed to by the dpump_dir1 directory object. The dpump_dir2 directory object specified on the LOGFILE parameter overrides the DIRECTORY parameter so that the log file is written to dpump_dir2.

You can apply the style via javascript. This is the Js code below that applies the filter to the image with the ID theImage.
function invert(){
document.getElementById("theImage").style.filter="invert(100%)";
}
And this is the
<img id="theImage" class="img-responsive" src="http://i.imgur.com/1H91A5Y.png"></img>
Now all you need to do is call invert() We do this when the image is clicked.
function invert(){_x000D_
document.getElementById("theImage").style.filter="invert(100%)";_x000D_
}
_x000D_
<h4> Click image to invert </h4>_x000D_
_x000D_
<img id="theImage" class="img-responsive" src="http://i.imgur.com/1H91A5Y.png" onClick="invert()" ></img>

Dynamic methods of an object may be created using Object Literal Extensions provided by ECMAScript 2015 (ES6):
const postfixes = ['foo', 'bar'];
const mainObj = {};
const makeDynamic = (postfix) => {
const newMethodName = 'instance: ' + postfix;
const tempObj = {
[newMethodName]() {
console.log(`called method ${newMethodName}`);
}
}
Object.assign(mainObj, tempObj);
return mainObj[newMethodName]();
}
const processPostfixes = (postfixes) => {
for (const postfix of postfixes) {
makeDynamic(postfix);
}
};
processPostfixes(postfixes);
console.log(mainObj);
The output of running the code above is:
"called method instance: foo"
"called method instance: bar"
Object {
"instance: bar": [Function anonymous],
"instance: foo": [Function anonymous]
}
There's a 'cheap and dirty' trick that I have used... shhhh don't tell anyone. If you output tab delimited text and make the file name *.xls then Excel opens it without objection, question or warning. So just crank the data out into a text file with tab delimitation and you can open it with Excel or Open Office.
Try using list.AddRange(VTSWeb.GetDailyWorktimeViolations(VehicleID2));
I'm not sure if you can alter the original element but how about switch from using the id attr to something else like data-id? Then just read the value of data-id for your hash value and it won't jump.
Two nitpicks. (1) Best not to use string literals for column alias - that is deprecated. (2) Just use style 120 to get the same value.
CASE
WHEN CreatedDate = '19000101' THEN ''
WHEN CreatedDate = '18000101' THEN ''

Here a full makefile example:
makefile
TARGET = prog
$(TARGET): main.o lib.a
gcc $^ -o $@
main.o: main.c
gcc -c $< -o $@
lib.a: lib1.o lib2.o
ar rcs $@ $^
lib1.o: lib1.c lib1.h
gcc -c -o $@ $<
lib2.o: lib2.c lib2.h
gcc -c -o $@ $<
clean:
rm -f *.o *.a $(TARGET)
explaining the makefile:
target: prerequisites
- the rule head$@
- means the target$^
- means all prerequisites$<
- means just the first prerequisitear
- a Linux tool to create, modify, and extract from archives see the man pages for further information. The options in this case mean:
r
- replace files existing inside the archivec
- create a archive if not already existents
- create an object-file index into the archiveTo conclude: The static library under Linux is nothing more than a archive of object files.

Your code is a no-op. By the definition of the loop, "item" has to be in Z. A "For ... in" loop in Python means "Loop though the list called 'z', each time you loop, give me the next item in the list, and call it 'item'"
http://docs.python.org/tutorial/controlflow.html#for-statements
I think your confusion arises from the fact that you're using the variable name "item" twice, to mean two different things.
This is little bit old thread - but maybe help someone who still search - I'm the one who search for that a year.
Solution may be "AWS Athena" where you can search over data like this
'SELECT user_name FROM S3Object WHERE cast(age as int) > 20'
Currently pricing is $5 for 1TB data - so for example, if your query search over one 1TB file 3times your cost is $15 - but for example if there is only 1column in "converted columnar format" what you want read, you'll pay 1/3 of price means $1.67/TB.
Declare you integer variable as nullable
eg: int? variable=0; variable=null;
First, array_length
should be an integer and not a string:
array_length = len(array_dates)
Second, your for
loop should be constructed using range
:
for i in range(array_length): # Use `xrange` for python 2.
Third, i
will increment automatically, so delete the following line:
i += 1
Note, one could also just zip
the two lists given that they have the same length:
import csv
dates = ['2020-01-01', '2020-01-02', '2020-01-03']
urls = ['www.abc.com', 'www.cnn.com', 'www.nbc.com']
csv_file_patch = '/path/to/filename.csv'
with open(csv_file_patch, 'w') as fout:
csv_file = csv.writer(fout, delimiter=';', lineterminator='\n')
result_array = zip(dates, urls)
csv_file.writerows(result_array)
-p|--parent
will be used if you are trying to create a directory with top-down
approach. That will create the parent directory then child and so on iff none exists.
-p, --parents no error if existing, make parent directories as needed
About rlidwka
it means giving full or administrative access. Found it here https://itservices.stanford.edu/service/afs/intro/permissions/unix.
Hello i now it past a lot of time from the original post but i got a similar problem and i want to share.
I got a datetime field with this format YYYY-MM-DD hh:mm:ss, and i want to access a whole day, so here is my solution.
The function DATE(), in MySQL: Extract the date part of a date or datetime expression.
SELECT * FROM `your_table` WHERE DATE(`your_datatime_field`)='2017-10-09'
with this i get all the row register in this day.
I hope its help anyone.
There is no subtyping relationship between arrays of primitive type, or between an array of a primitive type and array of a reference type. See JLS 4.10.3.
Therefore, the following is incorrect as a test to see if obj
is an array of any kind:
// INCORRECT!
public boolean isArray(final Object obj) {
return obj instanceof Object[];
}
Specifically, it doesn't work if obj
is 1-D array of primitives. (It does work for primitive arrays with higher dimensions though, because all array types are subtypes of Object
. But it is moot in this case.)
I use Google GWT so I am not allowed to use reflection :(
The best solution (to the isArray
array part of the question) depends on what counts as "using reflection".
In GWT, calling obj.getClass().isArray()
does not count as using reflection1, so that is the best solution.
Otherwise, the best way of figuring out whether an object has an array type is to use a sequence of instanceof
expressions.
public boolean isArray(final Object obj) {
return obj instanceof Object[] || obj instanceof boolean[] ||
obj instanceof byte[] || obj instanceof short[] ||
obj instanceof char[] || obj instanceof int[] ||
obj instanceof long[] || obj instanceof float[] ||
obj instanceof double[];
}
You could also try messing around with the name of the object's class as follows, but the call to obj.getClass()
is bordering on reflection.
public boolean isArray(final Object obj) {
return obj.getClass().toString().charAt(0) == '[';
}
1 - More precisely, the Class.isArray
method is listed as supported by GWT in this page.
I have found that creating a var to hold the WebElement
and the call the sendKeys()
works for me.
WebElement speedCurrentCell = driver.findElement(By.id("Speed_current"));
speedCurrentCell.sendKeys("1300");
After I have downloaded the binary from apache site I, have placed the extracted folder in /Library
So now the location of the settings.xml file is in:
/Library/apache_maven_3.6.3/conf
You could inspect the available apache2 modules:
$ ls /usr/lib/apache2/modules/
Or try to enable the php module, if you have the appropriate access:
$ a2enmod
Which module would you like to enable?
Your choices are: actions alias asis ...
... php5 proxy_ajp proxy_balancer proxy_connect ..

As always with Android there's lots of ways to do this, but assuming you simply want to run a piece of code a little bit later on the same thread, I use this:
new android.os.Handler(Looper.getMainLooper()).postDelayed(
new Runnable() {
public void run() {
Log.i("tag", "This'll run 300 milliseconds later");
}
},
300);
.. this is pretty much equivalent to
setTimeout(
function() {
console.log("This will run 300 milliseconds later");
},
300);
I'm using @foreach
when I send an entity that contains a list of entities ( for example to display 2 grids in 1 view )
For example if I'm sending as model the entity Foo that contains Foo1(List<Foo1>)
and Foo2(List<Foo2>)
I can refer to the first List with:
@foreach (var item in Model.Foo.Foo1)
{
@Html.DisplayFor(modelItem=> item.fooName)
}
You can make api calls by choosing the HTTP method and setting optional parameters:
$facebook->api('/me/feed/', 'post', array(
'message' => 'I want to display this message on my wall'
));
Submit Post to Facebook Wall :
Include the fbConfig.php file to connect Facebook API and get the access token.
Post message, name, link, description, and the picture will be submitted to Facebook wall. Post submission status will be shown.
If FB access token ($accessToken) is not available, the Facebook Login URL will be generated and the user would be redirected to the FB login page.
<?php
//Include FB config file
require_once 'fbConfig.php';
if(isset($accessToken)){
if(isset($_SESSION['facebook_access_token'])){
$fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
}else{
// Put short-lived access token in session
$_SESSION['facebook_access_token'] = (string) $accessToken;
// OAuth 2.0 client handler helps to manage access tokens
$oAuth2Client = $fb->getOAuth2Client();
// Exchanges a short-lived access token for a long-lived one
$longLivedAccessToken = $oAuth2Client->getLongLivedAccessToken($_SESSION['facebook_access_token']);
$_SESSION['facebook_access_token'] = (string) $longLivedAccessToken;
// Set default access token to be used in script
$fb->setDefaultAccessToken($_SESSION['facebook_access_token']);
}
//FB post content
$message = 'Test message from CodexWorld.com website';
$title = 'Post From Website';
$link = 'http://www.codexworld.com/';
$description = 'CodexWorld is a programming blog.';
$picture = 'http://www.codexworld.com/wp-content/uploads/2015/12/www-codexworld-com-programming-blog.png';
$attachment = array(
'message' => $message,
'name' => $title,
'link' => $link,
'description' => $description,
'picture'=>$picture,
);
try{
//Post to Facebook
$fb->post('/me/feed', $attachment, $accessToken);
//Display post submission status
echo 'The post was submitted successfully to Facebook timeline.';
}catch(FacebookResponseException $e){
echo 'Graph returned an error: ' . $e->getMessage();
exit;
}catch(FacebookSDKException $e){
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
}else{
//Get FB login URL
$fbLoginURL = $helper->getLoginUrl($redirectURL, $fbPermissions);
//Redirect to FB login
header("Location:".$fbLoginURL);
}

This allows you to just get the image data and set to the img src, which is cool.
var oReq = new XMLHttpRequest();
oReq.open("post", '/somelocation/getmypic', true );
oReq.responseType = "blob";
oReq.onload = function ( oEvent )
{
var blob = oReq.response;
var imgSrc = URL.createObjectURL( blob );
var $img = $( '<img/>', {
"alt": "test image",
"src": imgSrc
} ).appendTo( $( '#bb_theImageContainer' ) );
window.URL.revokeObjectURL( imgSrc );
};
oReq.send( null );
The basic idea is that the data is returned untampered with, it is placed in a blob and then a url is created to that object in memory. See here and here. Note supported browsers.
The hash is used by dictionaries and sets to quickly look up the object. A good starting point is Wikipedia's article on hash tables.
The hashes are just because your column width is not enough to display the "number".
About the sorting, you should review how you system region and language is configured. For the US region, Excel date input should be "5/17/2012" not "17/05/2012" (this 17-may-12).

Have you ever tried out the pandas package? It's perfect for this kind of search task and optimized too.
import pandas as pd
listOfDicts = [
{"name": "Tom", "age": 10},
{"name": "Mark", "age": 5},
{"name": "Pam", "age": 7}
]
# Create a data frame, keys are used as column headers.
# Dict items with the same key are entered into the same respective column.
df = pd.DataFrame(listOfDicts)
# The pandas dataframe allows you to pick out specific values like so:
df2 = df[ (df['name'] == 'Pam') & (df['age'] == 7) ]
# Alternate syntax, same thing
df2 = df[ (df.name == 'Pam') & (df.age == 7) ]
I've added a little bit of benchmarking below to illustrate pandas' faster runtimes on a larger scale i.e. 100k+ entries:
setup_large = 'dicts = [];\
[dicts.extend(({ "name": "Tom", "age": 10 },{ "name": "Mark", "age": 5 },\
{ "name": "Pam", "age": 7 },{ "name": "Dick", "age": 12 })) for _ in range(25000)];\
from operator import itemgetter;import pandas as pd;\
df = pd.DataFrame(dicts);'
setup_small = 'dicts = [];\
dicts.extend(({ "name": "Tom", "age": 10 },{ "name": "Mark", "age": 5 },\
{ "name": "Pam", "age": 7 },{ "name": "Dick", "age": 12 }));\
from operator import itemgetter;import pandas as pd;\
df = pd.DataFrame(dicts);'
method1 = '[item for item in dicts if item["name"] == "Pam"]'
method2 = 'df[df["name"] == "Pam"]'
import timeit
t = timeit.Timer(method1, setup_small)
print('Small Method LC: ' + str(t.timeit(100)))
t = timeit.Timer(method2, setup_small)
print('Small Method Pandas: ' + str(t.timeit(100)))
t = timeit.Timer(method1, setup_large)
print('Large Method LC: ' + str(t.timeit(100)))
t = timeit.Timer(method2, setup_large)
print('Large Method Pandas: ' + str(t.timeit(100)))
#Small Method LC: 0.000191926956177
#Small Method Pandas: 0.044392824173
#Large Method LC: 1.98827004433

This post is really old (it's 7 years old when I answered it), so no one of the other answers used the new and recommended way, which is HttpClient
class.
HttpClient
is considered the new API and it should replace the old ones (WebClient
and WebRequest
)
string url = "page url";
HttpClient client = new HttpClient();
using (HttpResponseMessage response = client.GetAsync(url).Result)
{
using (HttpContent content = response.Content)
{
string result = content.ReadAsStringAsync().Result;
}
}
for more information about how to use the HttpClient
class (especially in async cases), you can refer this question
NOTE 1: If you want to use async/await
string url = "page url";
HttpClient client = new HttpClient(); // actually only one object should be created by Application
using (HttpResponseMessage response = await client.GetAsync(url))
{
using (HttpContent content = response.Content)
{
string result = await content.ReadAsStringAsync();
}
}
NOTE 2: If use C# 8 features
string url = "page url";
HttpClient client = new HttpClient();
using HttpResponseMessage response = await client.GetAsync(url);
using HttpContent content = response.Content;
string result = await content.ReadAsStringAsync();
To show child or sibling elements it's possible with CSS only. If you use :hover
before combinators (+
, ~
, >
, space
). Then the style applies not to hovered element.
HTML
<body>
<div class="trigger">
Hover here.
</div>
<div class="hidden">
This message shows up.
</div>
</body>
CSS
.hidden { display: none; }
.trigger:hover + .hidden { display: inline; }
You need the "correlation id" (the "AS SS" thingy) on the sub-select to reference the fields in the "ON" condition. The id's assigned inside the sub select are not usable in the join.
SELECT
cs.CUSID
,dp.DEPID
FROM
CUSTMR cs
LEFT OUTER JOIN (
SELECT
DEPID
,DEPNAME
FROM
DEPRMNT
WHERE
dp.DEPADDRESS = 'TOKYO'
) ss
ON (
ss.DEPID = cs.CUSID
AND ss.DEPNAME = cs.CUSTNAME
)
WHERE
cs.CUSID != ''
In my case I had a symlink for the 404'd file and my Tomcat was not configured to allow symlinks.
I know that it is not likely to be the cause for most people, but if you are desperate, check this possibility just in case.
For me an easier, practical and direct way to understand what is going on, is that the following enumeration:
enum colors { red, green, blue };
Will be converted essentially to this:
var colors = { red: 0, green: 1, blue: 2,
[0]: "red", [1]: "green", [2]: "blue" }
Because of this, the following will be true:
colors.red === 0
colors[colors.red] === "red"
colors["red"] === 0
This creates a easy way to get the name of an enumerated as follows:
var color: colors = colors.red;
console.log("The color selected is " + colors[color]);
It also creates a nice way to convert a string to an enumerated value.
var colorName: string = "green";
var color: colors = colors.red;
if (colorName in colors) color = colors[colorName];
The two situations above are far more common situation, because usually you are far more interested in the name of a specific value and serializing values in a generic way.

You should have a clear idea of exceptions in java. In java there are checked exceptions and unchecked exceptions.
Checked exceptions are checked (not thrown,just checked) by the compiler at Compile time for the smooth execution of the program at run time.
NOTE: And in our program if their is a chance that a checked exception will rise, then we should handle that checked exception either by try catch or by throws key word.Otherwise we will get a compile time Error:
CE:Unexpected Exception java.io.FileNotFoundException;must be caught or declared to be thrown.
How to resolve: 1.Put your code in try catch block:
2.use throws keyword as shown by other guys above.
Advice:Read more about Exceptions.(I personally love this topic)
Just make a new list to populate, if the item for your list is not yet in the new list input it, else just move on to the next item in your original list.
for i in mylist:
if i not in newlist:
newlist.append(i)
I think this is the correct syntax, but my python is a bit shaky, I hope you at least get the idea.
