You may try these
int selectedIndex = myComboBox.getSelectedIndex();
-or-
Object selectedObject = myComboBox.getSelectedItem();
-or-
String selectedValue = myComboBox.getSelectedValue().toString();
create a new class called ComboKeyValue.java
public class ComboKeyValue {
private String key;
private String value;
public ComboKeyValue(String key, String value) {
this.key = key;
this.value = value;
}
@Override
public String toString(){
return key;
}
public String getKey() {
return key;
}
public String getValue() {
return value;
}
}
when you want to add a new item, just write the code as below
DefaultComboBoxModel model = new DefaultComboBoxModel();
model.addElement(new ComboKeyValue("key", "value"));
properties.setModel(model);
i think that is the solution

You can use np.logaddexp
(which implements the idea in @gg349's answer):
In [33]: d = np.array([[1089, 1093]])
In [34]: e = np.array([[1000, 4443]])
In [35]: log_res = np.logaddexp(-3*d[0,0], -3*d[0,1]) - np.logaddexp(-3*e[0,0], -3*e[0,1])
In [36]: log_res
Out[36]: -266.99999385580668
In [37]: res = exp(log_res)
In [38]: res
Out[38]: 1.1050349147204485e-116
Or you can use scipy.special.logsumexp
:
In [52]: from scipy.special import logsumexp
In [53]: res = np.exp(logsumexp(-3*d) - logsumexp(-3*e))
In [54]: res
Out[54]: 1.1050349147204485e-116
I think you want \b\w{1,10}\b
. The \b
matches a word boundary.
Of course, you could also replace the \b
and do ^\w{1,10}$
. This will match a word of at most 10 characters as long as its the only contents of the string. I think this is what you were doing before.
Since it's Java, you'll actually have to escape the backslashes: "\\b\\w{1,10}\\b"
. You probably knew this already, but it's gotten me before.
it's just your own style,nothing a bad style code,and nothing a good style code,just difference our code with the others.
Below is the easiest way in case if Anaconda is already installed.
1) Under "Files", there is an option called,"Upload".
2) Click on "Upload" button and it asks for the path of the file and select the file and click on upload button present beside the file.
Try
#include <inttypes.h>
...
printf("i [ %zu ] k [ %"PRIu32" ]\n", i, k);
The z
represents an integer of length same as size_t
, and the PRIu32
macro, defined in the C99 header inttypes.h
, represents an unsigned 32-bit integer.
With minimal editing to your code (Not sure if they've taught classes or not in your course), change:
def close_window(root):
root.destroy()
to
def close_window():
window.destroy()
and it should work.
Explanation:
Your version of close_window
is defined to expect a single argument, namely root
. Subsequently, any calls to your version of close_window
need to have that argument, or Python will give you a run-time error.
When you created a Button
, you told the button to run close_window
when it is clicked. However, the source code for Button widget is something like:
# class constructor
def __init__(self, some_args, command, more_args):
#...
self.command = command
#...
# this method is called when the user clicks the button
def clicked(self):
#...
self.command() # Button calls your function with no arguments.
#...
As my code states, the Button
class will call your function with no arguments. However your function is expecting an argument. Thus you had an error. So, if we take out that argument, so that the function call will execute inside the Button class, we're left with:
def close_window():
root.destroy()
That's not right, though, either, because root
is never assigned a value. It would be like typing in print(x)
when you haven't defined x
, yet.
Looking at your code, I figured you wanted to call destroy
on window
, so I changed root
to window
.
I don't know why but this works for me.
toolbar = (Toolbar) findViewById(R.id.main_toolbar);
toolbar.setSubtitle("Test Subtitle");
toolbar.inflateMenu(R.menu.main_manu);
For menu item click do this
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
if(item.getItemId()==R.id.item1)
{
// do something
}
else if(item.getItemId()== R.id.filter)
{
// do something
}
else{
// do something
}
return false;
}
});
Will update the 'why' part of this answer when I find a proper explanation.
Happy to help anyway :) Peace.
Looks like for both of your objects (inside the array), you have an extra closing brace after "Longitude".
=COUNTIFS(H5:H21000,">=100", H5:H21000,"<999")
Add a class to the body of each page:
<body class="home">
Or if you're on the contact page:
<body class="contact">
Then take this into consideration when you're creating your styles:
#sub-header ul li:hover,
body.home li.home,
body.contact li.contact { background-color: #000;}
#sub-header ul li:hover a,
body.home li.home a,
body.contact li.contact a { color: #fff; }
Lastly, apply class names to your list items:
<ul>
<li class="home"><a href="index.php">Home</a></li>
<li class="contact"><a href="contact.php">Contact Us</a></li>
<li class="about"><a href="about.php">About Us</a></li>
</ul>
This point, whenever you're on the body.home
page, your li.home a
link will have default styling indicating it is the current page.
If you're using express > 4.16
, you can use express.json()
and express.urlencoded()
The
express.json()
andexpress.urlencoded()
middleware have been added to provide request body parsing support out-of-the-box. This uses theexpressjs/body-parser
module module underneath, so apps that are currently requiring the module separately can switch to the built-in parsers.
Source Express 4.16.0 - Release date: 2017-09-28
With this,
const bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
becomes,
const express = require('express');
app.use(express.urlencoded({ extended: true }));
app.use(express.json());
It would be helpful to understand why you need to do this with lodash. If you just want to check if a key exists in an object, you don't need lodash.
myObject.options.hasOwnProperty('property');
If your looking to see if a value exists, you can use _.invert
_.invert(myObject.options)[value]
Just make option#1 Select Language:
<string-array name="array_name">
<item>Array Item One</item>
<item>Array Item Two</item>
<item>Array Item Three</item>
</string-array>
In your layout:
<Spinner
android:id="@+id/spinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawSelectorOnTop="true"
android:entries="@array/array_name"
/>
Delete
public static void deleteRecursive(File fileOrDirectory) {
if (fileOrDirectory.isDirectory())
for (File child : fileOrDirectory.listFiles())
deleteRecursive(child);
fileOrDirectory.delete();
}
check this link for above function.
Copy
public static void copyDirectoryOneLocationToAnotherLocation(File sourceLocation, File targetLocation)
throws IOException {
if (sourceLocation.isDirectory()) {
if (!targetLocation.exists()) {
targetLocation.mkdir();
}
String[] children = sourceLocation.list();
for (int i = 0; i < sourceLocation.listFiles().length; i++) {
copyDirectoryOneLocationToAnotherLocation(new File(sourceLocation, children[i]),
new File(targetLocation, children[i]));
}
} else {
InputStream in = new FileInputStream(sourceLocation);
OutputStream out = new FileOutputStream(targetLocation);
// Copy the bits from instream to outstream
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
}
}
Move
move is nothing just copy the folder one location to another then delete the folder thats it

The best and easiest way to clear a JLIST is:
myJlist.setListData(new String[0]);
like this:
import operator
list1 = sorted(csv1, key=operator.itemgetter(1, 2))
Well, you could call BigDecimal.intValue()
:
Converts this BigDecimal to an int. This conversion is analogous to a narrowing primitive conversion from double to short as defined in the Java Language Specification: any fractional part of this BigDecimal will be discarded, and if the resulting "BigInteger" is too big to fit in an int, only the low-order 32 bits are returned. Note that this conversion can lose information about the overall magnitude and precision of this BigDecimal value as well as return a result with the opposite sign.
You can then either explicitly call Integer.valueOf(int)
or let auto-boxing do it for you if you're using a sufficiently recent version of Java.
Tables displaying the issue:
and ==
Moral of the story use ===
table generation credit: https://github.com/dorey/JavaScript-Equality-Table
If you handle the draw.dt event after page.dt, you can detect exactly after moving the page. After work, draw.dt must be unbind
$(document).on("page.dt", () => {
$(document).on("draw.dt", changePage);
});
const changePage = () => {
// TODO
$(document).unbind("draw.dt", changePage);
}
You can do and
with nested conditions:
if %age% geq 2 (
if %age% leq 12 (
set class=child
)
)
or:
if %age% geq 2 if %age% leq 12 set class=child
You can do or
with a separate variable:
set res=F
if %hour% leq 6 set res=T
if %hour% geq 22 set res=T
if "%res%"=="T" (
set state=asleep
)
Using Node.js
sync mode:
var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")
async mode:
var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
var textByLine = text.split("\n")
});
UPDATE
As of at least Node 6, readFileSync
returns a Buffer
, so it must first be converted to a string in order for split
to work:
var text = fs.readFileSync("./mytext.txt").toString('utf-8');
Or
var text = fs.readFileSync("./mytext.txt", "utf-8");

You should have READ_EXTERNAL_STORAGE permission for reading sdcard. Add permission in manifest.xml

Update:
If you happen to "copy" settings.py
through symlinking, @forivall's answer is better:
~user/
project1/
mysite/
settings.py
templates/
wrong.html
project2/
mysite/
settings.py -> ~user/project1/settings.py
templates/
right.html
The method above will 'see' wrong.html
while @forivall's method will see right.html
In the absense of symlinks the two answers are identical.
It is about mathematical data transformations over time (or ignoring time).
In code this means functional purity and declarative programming.
State bugs are a huge problem in the standard imperative paradigm. Various bits of code may change some shared state at different "times" in the programs execution. This is hard to deal with.
In FRP you describe (like in declarative programming) how data transforms from one state to another and what triggers it. This allows you to ignore time because your function is simply reacting to its inputs and using their current values to create a new one. This means that the state is contained in the graph (or tree) of transformation nodes and is functionally pure.
This massively reduces complexity and debugging time.
Think of the difference between A=B+C in math and A=B+C in a program. In math you are describing a relationship that will never change. In a program, its says that "Right now" A is B+C. But the next command might be B++ in which case A is not equal to B+C. In math or declarative programming A will always be equal to B+C no matter what point in time you ask.
So by removing the complexities of shared state and changing values over time. You program is much easier to reason about.
An EventStream is an EventStream + some transformation function.
A Behaviour is an EventStream + Some value in memory.
When the event fires the value is updated by running the transformation function. The value that this produces is stored in the behaviours memory.
Behaviours can be composed to produce new behaviours that are a transformation on N other behaviours. This composed value will recalculate as the input events (behaviours) fire.
"Since observers are stateless, we often need several of them to simulate a state machine as in the drag example. We have to save the state where it is accessible to all involved observers such as in the variable path above."
Quote from - Deprecating The Observer Pattern http://infoscience.epfl.ch/record/148043/files/DeprecatingObserversTR2010.pdf
To those in the answer above. It's definitely JavaScript. It's just inline.
BTW the jQuery equivalent if you want to apply to all selects:
$('form select').on('change', function(){
$(this).closest('form').submit();
});
I used below regex to get that result also when its finished by a \
(\\[^\\]+)\\?$
The only reliable method is the one described by Igor M.
$pv_URIprotocol = isset($_SERVER["HTTPS"]) ? (($_SERVER["HTTPS"]==="on" || $_SERVER["HTTPS"]===1 || $_SERVER["SERVER_PORT"]===$pv_sslport) ? "https://" : "http://") : (($_SERVER["SERVER_PORT"]===$pv_sslport) ? "https://" : "http://");
Consider following: You are using nginx with fastcgi, by default(debian, ubuntu) fastgi_params contain directive:
fastcgi_param HTTPS $https;
if you are NOT using SSL, it gets translated as empty value, not 'off', not 0 and you are doomed.

For Eclipse: menu bar-> window -> show view then find "debug" option if not in list then select other ...
new window will open and then search using keyword "debug" -> select debug from list
it will added near console tab. use debug tab to terminate and remove previous executions. ( right clicking on executing process will show you many option including terminate)
This trick was mentioned under a few other questions, but not here yet.
All major compilers support __PRETTY_FUNC__
(GCC & Clang) /__FUNCSIG__
(MSVC) as an extension.
When used in a template like this:
template <typename T> const char *foo()
{
#ifdef _MSC_VER
return __FUNCSIG__;
#else
return __PRETTY_FUNCTION__;
#endif
}
It produces strings in a compiler-dependent format, that contain, among other things, the name of T
.
E.g. foo<float>()
returns:
"const char* foo() [with T = float]"
on GCC"const char *foo() [T = float]"
on Clang"const char *__cdecl foo<float>(void)"
on MSVCYou can easily parse the type names out of those strings. You just need to figure out how many 'junk' characters your compiler inserts before and after the type.
You can even do that completely at compile-time.
The resulting names can slightly vary between different compilers. E.g. GCC omits default template arguments, and MSVC prefixes classes with the word class
.
Here's an implementation that I've been using. Everything is done at compile-time.
Example usage:
std::cout << TypeName<float>() << '\n';
std::cout << TypeName(1.2f); << '\n';
Implementation:
#include <array>
#include <cstddef>
namespace impl
{
template <typename T>
constexpr const auto &RawTypeName()
{
#ifdef _MSC_VER
return __FUNCSIG__;
#else
return __PRETTY_FUNCTION__;
#endif
}
struct RawTypeNameFormat
{
std::size_t leading_junk = 0, trailing_junk = 0;
};
// Returns `false` on failure.
inline constexpr bool GetRawTypeNameFormat(RawTypeNameFormat *format)
{
const auto &str = RawTypeName<int>();
for (std::size_t i = 0;; i++)
{
if (str[i] == 'i' && str[i+1] == 'n' && str[i+2] == 't')
{
if (format)
{
format->leading_junk = i;
format->trailing_junk = sizeof(str)-i-3-1; // `3` is the length of "int", `1` is the space for the null terminator.
}
return true;
}
}
return false;
}
inline static constexpr RawTypeNameFormat format =
[]{
static_assert(GetRawTypeNameFormat(nullptr), "Unable to figure out how to generate type names on this compiler.");
RawTypeNameFormat format;
GetRawTypeNameFormat(&format);
return format;
}();
}
// Returns the type name in a `std::array<char, N>` (null-terminated).
template <typename T>
[[nodiscard]] constexpr auto CexprTypeName()
{
constexpr std::size_t len = sizeof(impl::RawTypeName<T>()) - impl::format.leading_junk - impl::format.trailing_junk;
std::array<char, len> name{};
for (std::size_t i = 0; i < len-1; i++)
name[i] = impl::RawTypeName<T>()[i + impl::format.leading_junk];
return name;
}
template <typename T>
[[nodiscard]] const char *TypeName()
{
static constexpr auto name = CexprTypeName<T>();
return name.data();
}
template <typename T>
[[nodiscard]] const char *TypeName(const T &)
{
return TypeName<T>();

Many of you must be landing here to find a solution for opaque border instead of a transparent one. In that case you can use rgba
, where a
stands for alpha
.
.your_class {
height: 100px;
width: 100px;
margin: 100px;
border: 10px solid rgba(255,255,255,.5);
}
Here, you can change the opacity
of the border
from 0-1
If you simply want a complete transparent border, the best thing to use is transparent
, like border: 1px solid transparent;
I have recently created a micro library that provides case-insensitive string helpers: https://github.com/nickuraltsev/ignore-case. (It uses toUpperCase
internally.)
var ignoreCase = require('ignore-case');
ignoreCase.equals('FOO', 'Foo'); // => true
ignoreCase.startsWith('foobar', 'FOO'); // => true
ignoreCase.endsWith('foobar', 'BaR'); // => true
ignoreCase.includes('AbCd', 'c'); // => true
ignoreCase.indexOf('AbCd', 'c'); // => 2
This worked for me. :)

Nimgoble's is the version I used in 2015. Thought I'd put it here as this question was top of the list in google for "wpf autocomplete textbox"
Install nuget package for project in Visual Studio
Add a reference to the library in the xaml:
xmlns:behaviors="clr-namespace:WPFTextBoxAutoComplete;assembly=WPFTextBoxAutoComplete"
Create a textbox and bind the AutoCompleteBehaviour to List<String>
(TestItems):
<TextBox Text="{Binding TestText, UpdateSourceTrigger=PropertyChanged}"
behaviors:AutoCompleteBehavior.AutoCompleteItemsSource="{Binding TestItems}" />
IMHO this is much easier to get started and manage than the other options listed above.
This snippet also solve this question with datePart function. I've also used the right()
trick to perform a rpad(x,2,"0")
.
option explicit
Wscript.Echo "Today is " & myDate(now)
' date formatted as your request
Function myDate(dt)
dim d,m,y, sep
sep = "-"
' right(..) here works as rpad(x,2,"0")
d = right("0" & datePart("d",dt),2)
m = right("0" & datePart("m",dt),2)
y = datePart("yyyy",dt)
myDate= m & sep & d & sep & y
End Function
The accepted answer works like a charm unless you're applying it to a vector. Since a vector is non-recursive, you'll get an error like this
$ operator is invalid for atomic vectors
You can use [
in that case
foo[order(foo["V1"]),]
I don't think you properly understood what you read. If it gets compiled to the correct type, then there is no difference. When I do this:
var i = 42;
The compiler knows it's an int, and generate code as if I had written
int i = 42;
As the post you linked to says, it gets compiled to the same type. It's not a runtime check or anything else requiring extra code. The compiler just figures out what the type must be, and uses that.
Is there a way to detect if a key is currently down in JavaScript?
Nope. The only possibility is monitoring each keyup
and keydown
and remembering.
after some period of time the key begins to repeat, firing off keydown and keyup events like a fiend.
It shouldn't. You'll definitely get keypress
repeating, and in many browsers you'll also get repeated keydown
, but if keyup
repeats, it's a bug.
Unfortunately it is not a completely unheard-of bug: on Linux, Chromium, and Firefox (when it is being run under GTK+, which it is in popular distros such as Ubuntu) both generate repeating keyup-keypress-keydown sequences for held keys, which are impossible to distinguish from someone hammering the key really fast.
You want the non-locale-aware floatval
function:
float floatval ( mixed $var ) - Gets the float value of a string.
Example:
$string = '122.34343The';
$float = floatval($string);
echo $float; // 122.34343
It simply wants the ASP control on your ASPX page. I usually place mine right under the tag, or inside first Content area in the master's body (if your using a master page)
<body>

Regex was proposed already, but not correctly:
<?php
$number = '00000004523423400023402340240';
$withoutLeadingZeroes = preg_replace('/^0+/', '', $number)
echo $withoutLeadingZeroes;
?>
output is then:
4523423400023402340240
Background on Regex:
the ^
signals beginning of string and the +
sign signals more or none of the preceding sign. Therefore, the regex ^0+
matches all zeroes at the beginning of a string.
If you install macports you can install gcc select, and then choose your gcc version.
/opt/local/bin/port install gcc_select
To see your versions use
port select --list gcc
To select a version use
sudo port select --set gcc gcc40
This is not an error, it is a warning from your Microsoft compiler.
Select your project and click "Properties" in the context menu.
In the dialog, chose Configuration Properties
-> C/C++
-> Preprocessor
In the field PreprocessorDefinitions add ;_CRT_SECURE_NO_WARNINGS
to turn those warnings off.
The spread operator is kinda cool.
this.results = [ ...this.results, ...data.results];
The spread operator allows you to easily place an expanded version of an array into another array.
.nil?
can be used on any object and is true if the object is nil.
.empty?
can be used on strings, arrays and hashes and returns true if:
Running .empty?
on something that is nil will throw a NoMethodError
.
That is where .blank?
comes in. It is implemented by Rails and will operate on any object as well as work like .empty?
on strings, arrays and hashes.
nil.blank? == true
false.blank? == true
[].blank? == true
{}.blank? == true
"".blank? == true
5.blank? == false
0.blank? == false
.blank?
also evaluates true on strings which are non-empty but contain only whitespace:
" ".blank? == true
" ".empty? == false
Rails also provides .present?
, which returns the negation of .blank?
.
Array gotcha: blank?
will return false
even if all elements of an array are blank. To determine blankness in this case, use all?
with blank?
, for example:
[ nil, '' ].blank? == false
[ nil, '' ].all? &:blank? == true
For those not getting a solution for older answers, i simply put my file name as the very first line in my code.
like so
#ruby_file_name_here.rb
puts "hello world"
Here's the best way to get a general File's size (works for directory and non-directory):
public static long getSize(File file) {
long size;
if (file.isDirectory()) {
size = 0;
for (File child : file.listFiles()) {
size += getSize(child);
}
} else {
size = file.length();
}
return size;
}
Edit: Note that this is probably going to be a time-consuming operation. Don't run it on the UI thread.
Also, here (taken from https://stackoverflow.com/a/5599842/1696171) is a nice way to get a user-readable String from the long returned:
public static String getReadableSize(long size) {
if(size <= 0) return "0";
final String[] units = new String[] { "B", "KB", "MB", "GB", "TB" };
int digitGroups = (int) (Math.log10(size)/Math.log10(1024));
return new DecimalFormat("#,##0.#").format(size/Math.pow(1024, digitGroups))
+ " " + units[digitGroups];
}
slicing operator. http://docs.python.org/tutorial/introduction.html#strings and scroll down a bit
You might consider using double slashes on your directory e.g
app.get('/',(req,res)=>{_x000D_
res.sendFile('C:\\Users\\DOREEN\\Desktop\\Fitness Finder' + '/index.html')_x000D_
})
_x000D_
Intent i1=new Intent(getApplicationContext(),StartUp_Page.class);
i1.setAction(Intent.ACTION_MAIN);
i1.addCategory(Intent.CATEGORY_HOME);
i1.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i1.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
i1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(i1);
finish();
You can also get the 500 error if you add your own assembly that contains the ApiController by overriding GetAssemblies of the DefaultAssembliesResolver and it is already in the array from base.GetAssemblies()
Case in point:
public class MyAssembliesResolver : DefaultAssembliesResolver
{
public override ICollection<Assembly> GetAssemblies()
{
var baseAssemblies = base.GetAssemblies();
var assemblies = new List<Assembly>(baseAssemblies);
assemblies.Add(Assembly.GetAssembly(typeof(MyAssembliesResolver)));
return new List<Assembly>(assemblies);
}
}
if the above code is in the same assembly as your Controller, that assembly will be in the list twice and will generate a 500 error since the Web API doesn't know which one to use.
Use StringBuilder
:
var sb = new StringBuilder();
using (XmlWriter xmlWriter = XmlWriter.Create(sb))
{
...
}
return sb.ToString();
If you want to stream any webpage, you can use the method below.
import java.io.*;
import java.net.*;
public class c {
public static String getHTML(String urlToRead) throws Exception {
StringBuilder result = new StringBuilder();
URL url = new URL(urlToRead);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
try (var reader = new BufferedReader(
new InputStreamReader(conn.getInputStream()))) {
for (String line; (line = reader.readLine()) != null; ) {
result.append(line);
}
}
return result.toString();
}
public static void main(String[] args) throws Exception
{
System.out.println(getHTML(args[0]));
}
}
Here's some full and simple code to do this. This worked fine when I used it.
var processStartInfo = new ProcessStartInfo
{
FileName = @"C:\SomeProgram",
Arguments = "Arguments",
RedirectStandardOutput = true,
UseShellExecute = false
};
var process = Process.Start(processStartInfo);
var output = process.StandardOutput.ReadToEnd();
process.WaitForExit();
Note that this only captures standard output; it doesn't capture standard error. If you want both, use this technique for each stream.
On Windows 10: Click change security property of myfile.ps1 and change "allow access" by right click / properties on myfile.ps1
Use .map()
(adapted from the example at http://api.jquery.com/map/):
var values = $("input[name='user_group[]']:checked").map(function(index,domElement) {
return $(domElement).val();
});
As @PavelAnossov answered, the canonical answer, use the word_tokenize
function in nltk:
from nltk import word_tokenize
sent = "This is my text, this is a nice way to input text."
word_tokenize(sent)
If your sentence is truly simple enough:
Using the string.punctuation
set, remove punctuation then split using the whitespace delimiter:
import string
x = "This is my text, this is a nice way to input text."
y = "".join([i for i in x if not in string.punctuation]).split(" ")
print y
Invoke-WebRequest can download HTTP, HTTPS, and FTP links.
$source = 'ftp://Blah.com/somefile.txt'
$target = 'C:\Users\someuser\Desktop\BlahFiles\somefile.txt'
$password = Microsoft.PowerShell.Security\ConvertTo-SecureString -String 'mypassword' -AsPlainText -Force
$credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList myuserid, $password
# Download
Invoke-WebRequest -Uri $source -OutFile $target -Credential $credential -UseBasicParsing
Since the cmdlet uses IE parsing you may need the -UseBasicParsing switch. Test to make sure.
I think you can safely say a for loop is faster.
I do admit that a regexp looks cleaner in terms of code. If it's a real bottleneck then use a for loop, otherwise stick with the regular expression for reasons of "elegance"
If you want to go for simplicity then just use
function isVowel(c) {
return ['a', 'e', 'i', 'o', 'u'].indexOf(c.toLowerCase()) !== -1
}
i don't know if it's the answer to your question but you can try setting the background color in the xml layout like this. It is easy, it always works
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="0xfff00000"
>
<TextView
android:id="@+id/text_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
</LinearLayout>
You can also do more fancy things with backgrounds by creating an xml background file with gradients which are cool and semi transparent, and refer to it for other use see example below:
the background.xml layout
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:angle="90"
android:startColor="#f0000000"
android:endColor="#ff444444"
android:type="linear" />
</shape>
</item>
</selector>
your layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@layout/background"
>
<TextView
android:id="@+id/text_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
</LinearLayout>
You can use this with HTTPClient API.
public RestTemplate getRestTemplateBypassingHostNameVerifcation() {
CloseableHttpClient httpClient = HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier()).build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);
return new RestTemplate(requestFactory);
}
If you use Width="*"
the column will fill to expand the available space.
If you want all columns to divide the grid equally apply this to all columns. If you just want one to fill the remaining space just apply it to that column with the rest being "Auto" or a specific width.
You can also use Width="0.25*"
(for example) if you want the column to take up 1/4 of the available width.
I think you want something along the line of:
Parent:
<Editor name={this.state.fileData} />
Editor:
var Editor = React.createClass({
displayName: 'Editor',
propTypes: {
name: React.PropTypes.string.isRequired
},
getInitialState: function() {
return {
value: this.props.name
};
},
handleChange: function(event) {
this.setState({value: event.target.value});
},
render: function() {
return (
<form id="noter-save-form" method="POST">
<textarea id="noter-text-area" name="textarea" value={this.state.value} onChange={this.handleChange} />
<input type="submit" value="Save" />
</form>
);
}
});
This is basically a direct copy of the example provided on https://facebook.github.io/react/docs/forms.html
Update for React 16.8:
import React, { useState } from 'react';
const Editor = (props) => {
const [value, setValue] = useState(props.name);
const handleChange = (event) => {
setValue(event.target.value);
};
return (
<form id="noter-save-form" method="POST">
<textarea id="noter-text-area" name="textarea" value={value} onChange={handleChange} />
<input type="submit" value="Save" />
</form>
);
}
Editor.propTypes = {
name: PropTypes.string.isRequired
};
According to the URI standard the path is for hierarchical parameters and the query is for non-hierarchical parameters. Ofc. it can be very subjective what is hierarchical for you.
In situations where multiple URIs are assigned to the same resource I like to put the parameters - necessary for identification - into the path and the parameters - necessary to build the representation - into the query. (For me this way it is easier to route.)
For example:
/users/123
and /users/123?fields="name, age"
/users
and /users?name="John"&age=30
For map reduce I like to use the following approaches:
/users?name="John"&age=30
/users/name:John/age:30
So it is really up to you (and your server side router) how you construct your URIs.
note: Just to mention these parameters are query parameters. So what you are really doing is defining a simple query language. By complex queries (which contain operators like and, or, greater than, etc.) I suggest you to use an already existing query language. The capabilities of URI templates are very limited...
I come across a situation where i need to insert the data in the database & simultaneously require the primary id using entity framework. Solution :
long id;
IGenericQueryRepository<myentityclass, Entityname> InfoBase = null;
try
{
InfoBase = new GenericQueryRepository<myentityclass, Entityname>();
InfoBase.Add(generalinfo);
InfoBase.Context.SaveChanges();
id = entityclassobj.ID;
return id;
}
You can achieve this using JQuery
HTML
<input type="file" id="FilUploader" />
JQuery
$("#FilUploader").change(function () {
var fileExtension = ['jpeg', 'jpg', 'png', 'gif', 'bmp'];
if ($.inArray($(this).val().split('.').pop().toLowerCase(), fileExtension) == -1) {
alert("Only formats are allowed : "+fileExtension.join(', '));
}
});

If i remember correctly, you need to use the "Shapes" property of your sheet.
Each Shape object has a TopLeftCell and BottomRightCell attributes that tell you the position of the image.
Here's a piece of code i used a while ago, roughly adapted to your needs. I don't remember the specifics about all those ChartObjects and whatnot, but here it is:
For Each oShape In ActiveSheet.Shapes
strImageName = ActiveSheet.Cells(oShape.TopLeftCell.Row, 1).Value
oShape.Select
'Picture format initialization
Selection.ShapeRange.PictureFormat.Contrast = 0.5: Selection.ShapeRange.PictureFormat.Brightness = 0.5: Selection.ShapeRange.PictureFormat.ColorType = msoPictureAutomatic: Selection.ShapeRange.PictureFormat.TransparentBackground = msoFalse: Selection.ShapeRange.Fill.Visible = msoFalse: Selection.ShapeRange.Line.Visible = msoFalse: Selection.ShapeRange.Rotation = 0#: Selection.ShapeRange.PictureFormat.CropLeft = 0#: Selection.ShapeRange.PictureFormat.CropRight = 0#: Selection.ShapeRange.PictureFormat.CropTop = 0#: Selection.ShapeRange.PictureFormat.CropBottom = 0#: Selection.ShapeRange.ScaleHeight 1#, msoTrue, msoScaleFromTopLeft: Selection.ShapeRange.ScaleWidth 1#, msoTrue, msoScaleFromTopLeft
'/Picture format initialization
Application.Selection.CopyPicture
Set oDia = ActiveSheet.ChartObjects.Add(0, 0, oShape.Width, oShape.Height)
Set oChartArea = oDia.Chart
oDia.Activate
With oChartArea
.ChartArea.Select
.Paste
.Export ("H:\Webshop_Zpider\Strukturbildene\" & strImageName & ".jpg")
End With
oDia.Delete 'oChartArea.Delete
Next
I used this method to clear the image from picturebox. It may help some one
private void btnClear1_Click(object sender, EventArgs e)
{
img1.ImageLocation = null;
}
Try the following:
str1="2345";
int x=str1.charAt(2)-'0';
//here x=4;
if u subtract by char '0', the ASCII value needs not to be known.
You can give the surrounding div
a
text-align: right
this will leave white space to the left of the image. (= the image will occupy the whole line).
If you want content to be shown to the left hand side of the image, use
float: right
on the image. However, the surrounding div
will then need overflow: auto
to stretch to the needed height.
Although this question is 5 years old I have come across a nice solution.
Use the 'DictionaryEntry' object to pair keys and values.
Set the 'DisplayMember' and 'ValueMember' properties to:
Me.myComboBox.DisplayMember = "Key"
Me.myComboBox.ValueMember = "Value"
To add items to the ComboBox:
Me.myComboBox.Items.Add(New DictionaryEntry("Text to be displayed", 1))
To retreive items like this:
MsgBox(Me.myComboBox.SelectedItem.Key & " " & Me.myComboBox.SelectedItem.Value)
You can use java.util.Arrays
class to transform the array T[?]
in a List<T>
object with methods like contains
:
Arrays.asList(int[] array).contains(int key);
.
character as a wildcard to match any single character.Example regex: a.c
abc // match
a c // match
azc // match
ac // no match
abbc // no match
[]
to match any characters in a set.\w
to match any single alphanumeric character: 0-9
, a-z
, A-Z
, and _
(underscore).\d
to match any single digit.\s
to match any single whitespace character.Example 1 regex: a[bcd]c
abc // match
acc // match
adc // match
ac // no match
abbc // no match
Example 2 regex: a[0-7]c
a0c // match
a3c // match
a7c // match
a8c // no match
ac // no match
a55c // no match
Use the hat in square brackets [^]
to match any single character except for any of the characters that come after the hat ^
.
Example regex: a[^abc]c
aac // no match
abc // no match
acc // no match
a c // match
azc // match
ac // no match
azzc // no match
(Don't confuse the ^
here in [^]
with its other usage as the start of line character: ^
= line start, $
= line end.)
Use the optional character ?
after any character to specify zero or one occurrence of that character. Thus, you would use .?
to match any single character optionally.
Example regex: a.?c
abc // match
a c // match
azc // match
ac // match
abbc // no match
Still broken? Try uninstalling @types/moment
.
So, I removed @types/moment
package from the package.json
file and it worked using:
import * as moment from 'moment'
Newer versions of moment
don't require the @types/moment
package as types are already included.
You could use dplyr::mutate_if()
to convert all character columns or dplyr::mutate_at()
for select named character columns to factors:
library(dplyr)
# all character columns to factor:
df <- mutate_if(df, is.character, as.factor)
# select character columns 'char1', 'char2', etc. to factor:
df <- mutate_at(df, vars(char1, char2), as.factor)
back to 2017:
use URL.createObjectURL( file ) to create local link to file system that user select;
don't forgot to free memory by using URL.revokeObjectURL()
For those still struggling with the error, make sure that you also import ReactiveFormsModule in your component 's module.ts file
meaning that you will import your ReactiveFormsModule in your app.module.ts and also in your mycomponent.module.ts file
Here is the Java Implementation of this approach:
public static int countAllFactors(int num)
{
TreeSet<Integer> tree_set = new TreeSet<Integer>();
for (int i = 1; i * i <= num; i+=1)
{
if (num % i == 0)
{
tree_set.add(i);
tree_set.add(num / i);
}
}
System.out.print(tree_set);
return tree_set.size();
}
Here is another function that works great for me, returns distance in kilometers:
function distance(lat1, lng1, lat2, lng2) {
var radlat1 = Math.PI * lat1 / 180;
var radlat2 = Math.PI * lat2 / 180;
var radlon1 = Math.PI * lng1 / 180;
var radlon2 = Math.PI * lng2 / 180;
var theta = lng1 - lng2;
var radtheta = Math.PI * theta / 180;
var dist = Math.sin(radlat1) * Math.sin(radlat2) + Math.cos(radlat1) * Math.cos(radlat2) * Math.cos(radtheta);
dist = Math.acos(dist);
dist = dist * 180 / Math.PI;
dist = dist * 60 * 1.1515;
//Get in in kilometers
dist = dist * 1.609344;
return dist;
}
A really simple approach:
class CustomError(Exception):
pass
raise CustomError("Hmm, seems like this was custom coded...")
Or, have the error raise without printing __main__
(may look cleaner and neater):
class CustomError(Exception):
__module__ = Exception.__module__
raise CustomError("Improved CustomError!")
As NSAttributedString
is primarily used with Core Text on iOS, you have to use CTParagraphStyle
instead of NSParagraphStyle
. There is no mutable variant.
For example:
CTTextAlignment alignment = kCTCenterTextAlignment;
CTParagraphStyleSetting alignmentSetting;
alignmentSetting.spec = kCTParagraphStyleSpecifierAlignment;
alignmentSetting.valueSize = sizeof(CTTextAlignment);
alignmentSetting.value = &alignment;
CTParagraphStyleSetting settings[1] = {alignmentSetting};
size_t settingsCount = 1;
CTParagraphStyleRef paragraphRef = CTParagraphStyleCreate(settings, settingsCount);
NSDictionary *attributes = @{(__bridge id)kCTParagraphStyleAttributeName : (__bridge id)paragraphRef};
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString:@"Hello World" attributes:attributes];
For the sake of completeness, what you are trying to create is a "modal window".
Numerous JS solutions allow you to create them with ease, take the time to find the one which best suits your needs.
I have used Tinybox 2 for small projects : http://sandbox.scriptiny.com/tinybox2/
It is also worth noting that this:
sc delete "ServiceName"
does not work in PowerShell, sc is an alias for the cmdlet Set-Content in PowerShell. You need to do:
sc.exe delete "ServiceName"
At least with Active Directory, I have been able to search by DistinguishedName by doing an LDAP query in this format (assuming that such a record exists with this distinguishedName):
"(distinguishedName=CN=Dev-India,OU=Distribution Groups,DC=gp,DC=gl,DC=google,DC=com)"
Personally I rarely write loops myself now when I can get away with it... I use the Jakarta commons libs:
Customer findCustomerByid(final int id){
return (Customer) CollectionUtils.find(customers, new Predicate() {
public boolean evaluate(Object arg0) {
return ((Customer) arg0).getId()==id;
}
});
}
Yay! I saved one line!

Some readers will have another issue and need this fix. read the links below. the same problem occured with visual studio 2015 with the advent of windows sdk 10 which brings up libucrt. ucrt is the windows implementation of C Runtime (CRT) aka the posix runtime library.

There are some kind of misunderstanding about lazy collections in JPA-Hibernate. First of all let's clear that why trying to read a lazy collection throws exceptions and not just simply returns NULL for converting or further use cases?.
That's because Null fields in Databases especially in joined columns have meaning and not simply not-presented state, like programming languages. when you're trying to interpret a lazy collection to Null value it means (on Datastore-side) there is no relations between these entities and it's not true. so throwing exception is some kind of best-practice and you have to deal with that not the Hibernate.
So as mentioned above I recommend to :
also as described in other answers there are plenty of approaches(eager fetch, joining etc.) or libraries and methods for doing that, but you have to setting up your view of what's happening before dealing with the problem and solving it.
Even when the scope is local, as in your example, you may access the parent scope through the property $parent
. Assume in the code below, that title
is defined on the parent scope. You may then access title as $parent.title
:
link : function(scope) { console.log(scope.$parent.title) },
template : "the parent has the title {{$parent.title}}"
However in most cases the same effect is better obtained using attributes.
An example of where I found the "&" notation, which is used "to pass data from the isolated scope via an expression and to the parent scope", useful (and a two-way databinding could not be used) was in a directive for rendering a special datastructure inside an ng-repeat.
<render data = "record" deleteFunction = "dataList.splice($index,1)" ng-repeat = "record in dataList" > </render>
One part of the rendering was a delete button and here it was useful to attach a deletefunction from the outside scope via &. Inside the render-directive it looks like
scope : { data = "=", deleteFunction = "&"},
template : "... <button ng-click = "deleteFunction()"></button>"
2-way databinding i.e. data = "="
can not be used as the delete function would run on every $digest
cycle, which is not good, as the record is then immediately deleted and never rendered.
To get the location of a script being sourced, you can use utils::getSrcDirectory
or utils::getSrcFilename
. So changing the working directory to that of the current file can be done with:
setwd(getSrcDirectory()[1])
This does not work in RStudio if you Run the code rather than Sourceing it. For that, you need to use rstudioapi::getActiveDocumentContext
.
setwd(dirname(rstudioapi::getActiveDocumentContext()$path))
This second solution requires that you are using RStudio as your IDE, of course.

If you are getting this Error java.lang.OutOfMemoryError this is the most common problem occurs in Android. This error is thrown by the Java Virtual Machine (JVM) when an object cannot be allocated due to lack of memory space.
Try this android:hardwareAccelerated="false" , android:largeHeap="true"
in your
manifest.xml file under application like this:
<application
android:name=".MyApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme"
android:hardwareAccelerated="false"
android:largeHeap="true" />
my case seems to be invalid JRE version.

I assume you build sample using maven.
Please check content of the JAR you're trying to run. Especially META-INFO/services
directory, file org.apache.hadoop.fs.FileSystem
. There should be list of filsystem implementation classes. Check line org.apache.hadoop.hdfs.DistributedFileSystem
is present in the list for HDFS and org.apache.hadoop.fs.LocalFileSystem
for local file scheme.
If this is the case, you have to override referred resource during the build.
Other possibility is you simply don't have hadoop-hdfs.jar
in your classpath but this has low probability. Usually if you have correct hadoop-client
dependency it is not an option.
You also have to modify the minimum size of the data and log files. DBCC SHRINKDATABASE will shrink the data inside the files you already have allocated. To shrink a file to a size smaller than its minimum size, use DBCC SHRINKFILE and specify the new size.
Use datetime.datetime.strptime

Can't change the default browser, but try this (found online a while ago). Add a bookmark in Safari called "Open in Chrome" with the following.
javascript:location.href=%22googlechrome%22+location.href.substring(4);
Will open the current page in Chrome. Not as convenient, but maybe someone will find it useful.
Works for me.
Its a Little Late but I found the same problem and i fixed it by a "\" in front of PDO
public function enabled() {
return in_array('mysql', \PDO::getAvailableDrivers());
}
I had this problem too. What worked for me was to first un-check the previously selected SDK version before checking the new desired version. Then click okay.
Have you tried moving the reduction step outside the loop? Right now you have a data dependency that really isn't needed.
Try:
uint64_t subset_counts[4] = {};
for( unsigned k = 0; k < 10000; k++){
// Tight unrolled loop with unsigned
unsigned i=0;
while (i < size/8) {
subset_counts[0] += _mm_popcnt_u64(buffer[i]);
subset_counts[1] += _mm_popcnt_u64(buffer[i+1]);
subset_counts[2] += _mm_popcnt_u64(buffer[i+2]);
subset_counts[3] += _mm_popcnt_u64(buffer[i+3]);
i += 4;
}
}
count = subset_counts[0] + subset_counts[1] + subset_counts[2] + subset_counts[3];
You also have some weird aliasing going on, that I'm not sure is conformant to the strict aliasing rules.
You do not exactly define what the dictionaries should look like, but most likely you are referring to QuerySet.values()
. From the official django documentation:
Returns a
ValuesQuerySet
— aQuerySet
subclass that returns dictionaries when used as an iterable, rather than model-instance objects.Each of those dictionaries represents an object, with the keys corresponding to the attribute names of model objects.
To understand get and set, it's all related to how variables are passed between different classes.
The get method is used to obtain or retrieve a particular variable value from a class.
A set value is used to store the variables.
The whole point of the get and set is to retrieve and store the data values accordingly.
What I did in this old project was I had a User class with my get and set methods that I used in my Server class.
The User class's get set methods:
public int getuserID()
{
//getting the userID variable instance
return userID;
}
public String getfirstName()
{
//getting the firstName variable instance
return firstName;
}
public String getlastName()
{
//getting the lastName variable instance
return lastName;
}
public int getage()
{
//getting the age variable instance
return age;
}
public void setuserID(int userID)
{
//setting the userID variable value
this.userID = userID;
}
public void setfirstName(String firstName)
{
//setting the firstName variable text
this.firstName = firstName;
}
public void setlastName(String lastName)
{
//setting the lastName variable text
this.lastName = lastName;
}
public void setage(int age)
{
//setting the age variable value
this.age = age;
}
}
Then this was implemented in the run()
method in my Server class as follows:
//creates user object
User use = new User(userID, firstName, lastName, age);
//Mutator methods to set user objects
use.setuserID(userID);
use.setlastName(lastName);
use.setfirstName(firstName);
use.setage(age);
Do you can use ->stateless()
before the ->redirect()
.
Then you dont need the session anymore.
I've create a solution, mixed the information of varius post.
Its a form, that contains a label and one textbox. The console output is redirected to the textbox.
There are too a class called ConsoleView that implements three publics methods: Show(), Close(), and Release(). The last one is for leave open the console and activate the Close button for view results.
The forms is called FrmConsole. Here are the XAML and the c# code.
The use is very simple:
ConsoleView.Show("Title of the Console");
For open the console. Use:
System.Console.WriteLine("The debug message");
For output text to the console.
Use:
ConsoleView.Close();
For Close the console.
ConsoleView.Release();
Leaves open the console and enables the Close button

I hope this result usefull.
Here is one simple solution
public static void main(String[] args) {
//Without using Arrays.sort function
int i;
int nos[] = {12,9,-4,-1,3,10,34,12,11};
System.out.print("Values before sorting: \n");
for(i = 0; i < nos.length; i++)
System.out.println( nos[i]+" ");
sort(nos, nos.length);
System.out.print("Values after sorting: \n");
for(i = 0; i <nos.length; i++){
System.out.println(nos[i]+" ");
}
}
private static void sort(int nos[], int n) {
for (int i = 1; i < n; i++){
int j = i;
int B = nos[i];
while ((j > 0) && (nos[j-1] > B)){
nos[j] = nos[j-1];
j--;
}
nos[j] = B;
}
}
And the output is:
Values before sorting:
12
9
-4
-1
3
10
34
12
11
Values after sorting:
-4
-1
3

Late answering, probably everybody knows about yield
now, but some better documentation has come along.
Adapting an example from "Javascript's Future: Generators" by James Long for the official Harmony standard:
function * foo(x) {
while (true) {
x = x * 2;
yield x;
}
}
"When you call foo, you get back a Generator object which has a next method."
var g = foo(2);
g.next(); // -> 4
g.next(); // -> 8
g.next(); // -> 16
So yield
is kind of like return
: you get something back. return x
returns the value of x
, but yield x
returns a function, which gives you a method to iterate toward the next value. Useful if you have a potentially memory intensive procedure that you might want to interrupt during the iteration.
I know this is an old question, but I was struggling to do this with a time period over 2 hours, so this might help someone. Also, several of the answers don't actually plot against time, giving equal space whatever the duration.
Firstly, as @jameswarren says, use a scatter graph. Then right-click the horizontal axis and choose Format Axis.
Under Number, select Time, and at this point you may find your scale goes a bit crazy, because it chooses to scale the axis by days. So go back to Axis Options and select Fixed for the Minimum, Maximum and Major unit scales.
To set the unit to hours, type in 1/24 = 0.0416667 (I used half that to get half-hourly increments). To make this start at a round number, multiply it by your preferred number of hours and type that into the Minimum box. In my case 08:00 = 0.333333
Try specifying a DC in DomainB using the -Server
property. Ex:
Get-ADUser -Server "dc01.DomainB.local" -Filter {EmailAddress -like "*Smith_Karla*"} -Properties EmailAddress
As described by the link I've given in comment, this
$('p[MyTag]').each(function(index) {
document.write(index + ': ' + $(this).text() + "<br>");});
works (playable example).
Suggest you add handling to test if any of the sheets to be renamed already exist:
Sub Test()
Dim ws As Worksheet
Dim ws1 As Worksheet
Dim strErr As String
On Error Resume Next
For Each ws In ActiveWorkbook.Sheets
Set ws1 = Sheets(ws.Name & "_v1")
If ws1 Is Nothing Then
ws.Name = ws.Name & "_v1"
Else
strErr = strErr & ws.Name & "_v1" & vbNewLine
End If
Set ws1 = Nothing
Next
On Error GoTo 0
If Len(strErr) > 0 Then MsgBox strErr, vbOKOnly, "these sheets already existed"
End Sub
For reloading the page for a given route path :-
$location.path('/path1/path2');
$route.reload();
SELECT MAX(ID) FROM tablename LIMIT 1
Use this query to find the highest ID in the MySQL table.

You can use the strip() to remove trailing and leading spaces.
>>> s = ' abd cde '
>>> s.strip()
'abd cde'
Note: the internal spaces are preserved
Very simple to fix, you just need to turn the parameter to writerow into a list.
for item in RESULTS:
wr.writerow([item,])
I had a similar error, my console looked like this:
My problem was that I was running my site in a sub folder since the company was using one top domain and no sub domains. Like this:
host.com/app1
host.com/app2
My code looked like this for including scripts which worked fine on localhost but not in app1 or app2:
<link rel="stylesheet" type="text/css" href="/Content/css/font-awesome.min.css" />
Added a tilde sign ~
to src and then everything worked:
<link rel="stylesheet" type="text/css" href="~/Content/css/font-awesome.min.css" />
Explanation of ~
vs /
:
/
- Site root~/
- Root directory of the application/
will return the root of the site (http://host.com/
),
~/
will return the root of the application (http://host.com/app1/
).
Using your example, you could do:
public void doit(A a) {
if(a instanceof B) {
// needs to cast to B to access draw2 which isn't present in A
// note that this is probably not a good OO-design, but that would
// be out-of-scope for this discussion :)
((B)a).draw2();
}
a.draw();
}
With the last version of Django Rest Framework, you need to create a method in your model with the name of the field you want to add. No need for @property
and source='field'
raise an error.
class Foo(models.Model):
. . .
def foo(self):
return 'stuff'
. . .
class FooSerializer(ModelSerializer):
foo = serializers.ReadOnlyField()
class Meta:
model = Foo
fields = ('foo',)
<form method="post" action="servletName">
<input type="submit" id="btn1" name="btn1"/>
<input type="submit" id="btn2" name="btn2"/>
</form>
on pressing it request will go to servlet on the servlet page check which button is pressed and then accordingly call the needed method as objectName.method
Please Try, if use "extends AppCompatActivity" and present actionbar.
ActionBar eksinbar=getSupportActionBar();
if (eksinbar != null) {
eksinbar.setDisplayHomeAsUpEnabled(true);
eksinbar.setHomeAsUpIndicator(R.mipmap.imagexxx);
}
vim +21490go script.py
From the command line will open the file and take you to position 21490
in the buffer.
Triggering it from the command line like this allows you to automate a script to parse the exception message and open the file to the problem position.
Excerpt from man vim
:
+{command} -c {command}
{command}
will be executed after the first file has been read.{command}
is interpreted as an Ex command. If the{command}
contains spaces it must be enclosed in double quotes (this depends on the shell that is used).
Just solved this problem a different way.
Control drag the button to the viewController.h
file and create an action (Sent Event: Touch Up Inside) like :
(IBAction)ExitKeyboard:(id)sender;
In ViewController.m
should look like :
(IBAction)ExitKeyboard:(id)sender {
[self.view endEditing:TRUE];
}
This is building off the work Daniel Little did for this question, but taking into account daylight savings time (works for dates 01-01 1902 and greater due to int limit on dateadd function):
We first need to create a table that will store the date ranges for daylight savings time (source: History of time in the United States):
CREATE TABLE [dbo].[CFG_DAY_LIGHT_SAVINGS_TIME](
[BEGIN_DATE] [datetime] NULL,
[END_DATE] [datetime] NULL,
[YEAR_DATE] [smallint] NULL
) ON [PRIMARY]
GO
INSERT INTO CFG_DAY_LIGHT_SAVINGS_TIME VALUES

If you need to return an IHttpActionResult and want to return the error code plus a message, use:
return ResponseMessage(Request.CreateErrorResponse(HttpStatusCode.NotModified, "Error message here"));
Try this:
<?php
$handle = fopen ("specialchars.csv","r");
echo '<table border="1"><tr><td>First name</td><td>Last name</td></tr><tr>';
while ($data = fgetcsv ($handle, 1000, ";")) {
$data = array_map("utf8_encode", $data); //added
$num = count ($data);
for ($c=0; $c < $num; $c++) {
// output data
echo "<td>$data[$c]</td>";
}
echo "</tr><tr>";
}
?>

While only a few lines are required to plot multiple/overlapping histograms in ggplot2, the results are't always satisfactory. There needs to be proper use of borders and coloring to ensure the eye can differentiate between histograms.
The following functions balance border colors, opacities, and superimposed density plots to enable the viewer to differentiate among distributions.
Single histogram:
plot_histogram <- function(df, feature) {
plt <- ggplot(df, aes(x=eval(parse(text=feature)))) +
geom_histogram(aes(y = ..density..), alpha=0.7, fill="#33AADE", color="black") +
geom_density(alpha=0.3, fill="red") +
geom_vline(aes(xintercept=mean(eval(parse(text=feature)))), color="black", linetype="dashed", size=1) +
labs(x=feature, y = "Density")
print(plt)
}
Multiple histogram:
plot_multi_histogram <- function(df, feature, label_column) {
plt <- ggplot(df, aes(x=eval(parse(text=feature)), fill=eval(parse(text=label_column)))) +
geom_histogram(alpha=0.7, position="identity", aes(y = ..density..), color="black") +
geom_density(alpha=0.7) +
geom_vline(aes(xintercept=mean(eval(parse(text=feature)))), color="black", linetype="dashed", size=1) +
labs(x=feature, y = "Density")
plt + guides(fill=guide_legend(title=label_column))
}
Usage:
Simply pass your data frame into the above functions along with desired arguments:
plot_histogram(iris, 'Sepal.Width')
plot_multi_histogram(iris, 'Sepal.Width', 'Species')
The extra parameter in plot_multi_histogram is the name of the column containing the category labels.
We can see this more dramatically by creating a dataframe with many different distribution means:
a <-data.frame(n=rnorm(1000, mean = 1), category=rep('A', 1000))
b <-data.frame(n=rnorm(1000, mean = 2), category=rep('B', 1000))
c <-data.frame(n=rnorm(1000, mean = 3), category=rep('C', 1000))
d <-data.frame(n=rnorm(1000, mean = 4), category=rep('D', 1000))
e <-data.frame(n=rnorm(1000, mean = 5), category=rep('E', 1000))
f <-data.frame(n=rnorm(1000, mean = 6), category=rep('F', 1000))
many_distros <- do.call('rbind', list(a,b,c,d,e,f))
Passing data frame in as before (and widening chart using options):
options(repr.plot.width = 20, repr.plot.height = 8)
plot_multi_histogram(many_distros, 'n', 'category')

made a quick demo yesterday that actually does what your talking about. http://bit.ly/10clOM9 this demo does the parallax based on the accelerometer so it works best on an iPhone itself. I basically just copy the content we are overlaying into a fixed position element that gets blurred.
note: swipe up to see the panel.
(i used horrible css id's but you get the idea)
#frost{
position: fixed;
bottom: 0;
left:0;
width: 100%;
height: 100px;
overflow: hidden;
-webkit-transition: all .5s;
}
#background2{
-webkit-filter: blur(15px) brightness(.2);
}
#content2fixed{
position: fixed;
bottom: 9px;
left: 9px;
-webkit-filter: blur(10px);
}
You can achieve your results with two methods:-
First Method define position values:-
HTML
<ul>
<li>Hello</li>
<li>Hello world</li>
</ul>
CSS
ul{
width:100px;
}
ul li{
border:1px solid orange;
background: url("http://www.adaweb.net/Portals/0/Images/arrow1.gif") no-repeat 90% 5px;
}
ul li:hover{
background: yellow url("http://www.adaweb.net/Portals/0/Images/arrow1.gif") no-repeat 90% 5px;
}
First Demo:- http://jsfiddle.net/QeGAd/18/
Second Method by CSS :before:after Selectors
HTML
<ul>
<li>Hello</li>
<li>Hello world</li>
CSS
ul{
width:100px;
}
ul li{
border:1px solid orange;
}
ul li:after {
content: " ";
padding-right: 16px;
background: url("http://www.adaweb.net/Portals/0/Images/arrow1.gif") no-repeat center right;
}
ul li:hover {

}
ul li:hover:after {

Come, let us recurse together.
def locations_of_substring(string, substring):
"""Return a list of locations of a substring."""
substring_length = len(substring)
def recurse(locations_found, start):
location = string.find(substring, start)
if location != -1:
return recurse(locations_found + [location], location+substring_length)
else:
return locations_found
return recurse([], 0)
print(locations_of_substring('this is a test for finding this and this', 'this'))
# prints [0, 27, 36]
No need for regular expressions this way.
This is kind of an old question but I wanted to mentioned here the pathlib library in Python3.
If you write:
from pathlib import Path
path: str = 'C:\\Users\\myUserName\\project\\subfolder'
osDir = Path(path)
or
path: str = "C:\\Users\\myUserName\\project\\subfolder"
osDir = Path(path)
osDir will be the same result.
Also if you write it as:
path: str = "subfolder"
osDir = Path(path)
absolutePath: str = str(Path.absolute(osDir))
you will get back the absolute directory as
'C:\\Users\\myUserName\\project\\subfolder'
You can check more for the pathlib library here.
The fastest MySQL
solution, without inner queries and without GROUP BY
:
SELECT m.* -- get the row that contains the max value
FROM topten m -- "m" from "max"
LEFT JOIN topten b -- "b" from "bigger"
ON m.home = b.home -- match "max" row with "bigger" row by `home`
AND m.datetime < b.datetime -- want "bigger" than "max"
WHERE b.datetime IS NULL -- keep only if there is no bigger than max
Explanation:
Join the table with itself using the home
column. The use of LEFT JOIN
ensures all the rows from table m
appear in the result set. Those that don't have a match in table b
will have NULL
s for the columns of b
.
The other condition on the JOIN
asks to match only the rows from b
that have bigger value on the datetime
column than the row from m
.
Using the data posted in the question, the LEFT JOIN
will produce this pairs:
+------------------------------------------+--------------------------------+
| the row from `m` | the matching row from `b` |
|------------------------------------------|--------------------------------|
| id home datetime player resource | id home datetime ... |
|----|-----|------------|--------|---------|------|------|------------|-----|
| 1 | 10 | 04/03/2009 | john | 399 | NULL | NULL | NULL | ... | *
| 2 | 11 | 04/03/2009 | juliet | 244 | NULL | NULL | NULL | ... | *
| 5 | 12 | 04/03/2009 | borat | 555 | NULL | NULL | NULL | ... | *
| 3 | 10 | 03/03/2009 | john | 300 | 1 | 10 | 04/03/2009 | ... |
| 4 | 11 | 03/03/2009 | juliet | 200 | 2 | 11 | 04/03/2009 | ... |
| 6 | 12 | 03/03/2009 | borat | 500 | 5 | 12 | 04/03/2009 | ... |
| 7 | 13 | 24/12/2008 | borat | 600 | 8 | 13 | 01/01/2009 | ... |
| 8 | 13 | 01/01/2009 | borat | 700 | NULL | NULL | NULL | ... | *
+------------------------------------------+--------------------------------+
Finally, the WHERE
clause keeps only the pairs that have NULL
s in the columns of b
(they are marked with *
in the table above); this means, due to the second condition from the JOIN
clause, the row selected from m
has the biggest value in column datetime
.

(3, 'b', 4), (3, 'b', 5)]
>>> list(product([1,2,3]))
[(1,), (2,), (3,)]
>>> list(product([]))

Seems, that I found the solution, but my idea is flawed. By doing this FileFormat:= _ xlOpenXMLWorkbook, it drops out a popup saying, the you cannot save this workbook as a file without Macro enabled. So, is this impossible?

Essentially, an operating system's windowing system exposes some API calls that you can perform to do jobs like create a window, or put a button on the window. Basically, you get a suite of header files and you can call functions in those imported libraries, just like you'd do with stdlib and printf
.
Each operating system comes with its own GUI toolkit, suite of header files, and API calls, and their own way of doing things. There are also cross platform toolkits like GTK, Qt, and wxWidgets that help you build programs that work anywhere. They achieve this by having the same API calls on each platform, but a different implementation for those API functions that call down to the native OS API calls.
One thing they'll all have in common, which will be different from a CLI program, is something called an event loop. The basic idea there is somewhat complicated, and difficult to compress, but in essence it means that not a hell of a lot is going in in your main class/main function, except:
There are plenty of resources about event based programming. If you have any experience with JavaScript, it's the same basic idea, except that you, the scripter have no access or control over the event loop itself, or what events there are, your only job is to write and register handlers.
You should keep in mind that GUI programming is incredibly complicated and difficult, in general. If you have the option, it's actually much easier to just integrate an embedded webserver into your program and have an HTML/web based interface. The one exception that I've encountered is Apple's Cocoa+Xcode +interface builder + tutorials that make it easily the most approachable environment for people new to GUI programming that I've seen.

The others are (from git help log
):
--date=(relative|local|default|iso|rfc|short|raw)
Only takes effect for dates shown in human-readable format,
such as when using "--pretty". log.date config variable
sets a default value for log command’s --date option.
--date=relative shows dates relative to the current time, e.g. "2 hours ago".
--date=local shows timestamps in user’s local timezone.
--date=iso (or --date=iso8601) shows timestamps in ISO 8601 format.
--date=rfc (or --date=rfc2822) shows timestamps in RFC 2822 format,
often found in E-mail messages.
--date=short shows only date but not time, in YYYY-MM-DD format.
--date=raw shows the date in the internal raw git format %s %z format.
--date=default shows timestamps in the original timezone
(either committer’s or author’s).
There is no built-in way that I know of to create a custom format, but you can do some shell magic.
timestamp=`git log -n1 --format="%at"`
my_date=`perl -e "print scalar localtime ($timestamp)"`
git log -n1 --pretty=format:"Blah-blah $my_date"
The first step here gets you a millisecond timestamp. You can change the second line to format that timestamp however you want. This example gives you something similar to --date=local
, with a padded day.
And if you want permanent effect without typing this every time, try
git config log.date iso
Or, for effect on all your git usage with this account
git config --global log.date iso

ApplicationId must be of type UniqueIdentifier
. Your code works fine if you do:
DECLARE @TTEST TABLE
(
TEST UNIQUEIDENTIFIER
)
DECLARE @UNIQUEX UNIQUEIDENTIFIER
SET @UNIQUEX = NEWID();
INSERT INTO @TTEST
(TEST)
VALUES
(@UNIQUEX);
SELECT * FROM @TTEST
Therefore I would say it is safe to assume that ApplicationId
is not the correct data type.

The HTTP 415 Unsupported Media Type client error response code indicates that the server refuses to accept the request because the payload format is in an unsupported format.
The format problem might be due to the request's indicated Content-Type or Content-Encoding, or as a result of inspecting the data directly.
In other words, such is seen in this example.
Content-Type: application/json
and Accept: application/json
. Otherwise, it will assume the defaultFor me the issue was android studio was not able to establish connection with 'https://jcenter.bintray.com/'

The title of the question asks about precision. BigDecimal distinguishes between scale and precision. Scale is the number of decimal places. You can think of precision as the number of significant figures, also known as significant digits.
Some examples in Clojure.
(.scale 0.00123M) ; 5
(.precision 0.00123M) ; 3
(In Clojure, The M
designates a BigDecimal literal. You can translate the Clojure to Java if you like, but I find it to be more compact than Java!)
You can easily increase the scale:
(.setScale 0.00123M 7) ; 0.0012300M
But you can't decrease the scale in the exact same way:
(.setScale 0.00123M 3) ; ArithmeticException Rounding necessary
You'll need to pass a rounding mode too:
(.setScale 0.00123M 3 BigDecimal/ROUND_HALF_EVEN) ;
; Note: BigDecimal would prefer that you use the MathContext rounding
; constants, but I don't have them at my fingertips right now.
So, it is easy to change the scale. But what about precision? This is not as easy as you might hope!
It is easy to decrease the precision:
(.round 3.14159M (java.math.MathContext. 3)) ; 3.14M
But it is not obvious how to increase the precision:
(.round 3.14159M (java.math.MathContext. 7)) ; 3.14159M (unexpected)
For the skeptical, this is not just a matter of trailing zeros not being displayed:
(.precision (.round 3.14159M (java.math.MathContext. 7))) ; 6
; (same as above, still unexpected)
FWIW, Clojure is careful with trailing zeros and will show them:
4.0000M ; 4.0000M
(.precision 4.0000M) ; 5
Back on track... You can try using a BigDecimal constructor, but it does not set the precision any higher than the number of digits you specify:
(BigDecimal. "3" (java.math.MathContext. 5)) ; 3M
(BigDecimal. "3.1" (java.math.MathContext. 5)) ; 3.1M
So, there is no quick way to change the precision. I've spent time fighting this while writing up this question and with a project I'm working on. I consider this, at best, A CRAZYTOWN API, and at worst a bug. People. Seriously?
So, best I can tell, if you want to change precision, you'll need to do these steps:
These steps, as Clojure code:
(def x 0.000691M) ; the input number
(def p' 1) ; desired precision
(def s' (+ (.scale x) p' (- (.precision x)))) ; desired new scale
(.setScale x s' BigDecimal/ROUND_HALF_EVEN)
; 0.0007M
I know, this is a lot of steps just to change the precision!
Why doesn't BigDecimal already provide this? Did I overlook something?
If you're simply sharing a counter, consider using an AtomicInteger or another suitable class from the java.util.concurrent.atomic package:
public class Test {
private final static AtomicInteger count = new AtomicInteger(0);
public void foo() {
count.incrementAndGet();
}
}
These can all be done with DateTime.Add(TimeSpan)
since it supports positive and negative timespans.
DateTime original = new DateTime(year, month, day, 8, 0, 0);
DateTime updated = original.Add(new TimeSpan(5,0,0));
DateTime original = new DateTime(year, month, day, 17, 0, 0);
DateTime updated = original.Add(new TimeSpan(-2,0,0));
DateTime original = new DateTime(year, month, day, 17, 30, 0);
DateTime updated = original.Add(new TimeSpan(0,45,0));
Or you can also use the DateTime.Subtract(TimeSpan)
method analogously.
From the Android Developers page,
onPause():
Called when the system is about to start resuming a previous activity. This is typically used to commit unsaved changes to persistent data, stop animations and other things that may be consuming CPU, etc. Implementations of this method must be very quick because the next activity will not be resumed until this method returns. Followed by either onResume() if the activity returns back to the front, or onStop() if it becomes invisible to the user.
onStop():
Called when the activity is no longer visible to the user, because another activity has been resumed and is covering this one. This may happen either because a new activity is being started, an existing one is being brought in front of this one, or this one is being destroyed. Followed by either onRestart() if this activity is coming back to interact with the user, or onDestroy() if this activity is going away.
Now suppose there are three Activities and you go from A to B, then onPause of A will be called now from B to C, then onPause of B and onStop of A will be called.
The paused Activity gets a Resume and Stopped gets Restarted.
When you call this.finish()
, onPause-onStop-onDestroy will be called. The main thing to remember is: paused Activities get Stopped and a Stopped activity gets Destroyed whenever Android requires memory for other operations.
I hope it's clear enough.
L= {'a':'a','d':'d', 'h':'h'}
index= ['a','d','h']
for keys in index:
print(L[keys])
I would use a Dict add
desired keys
to index
You can run another migration, just for the index:
class AddIndexToTable < ActiveRecord::Migration
def change
add_index :table, :user_id
end
end
You need to load the URL Helper in order to use base_url()
. In your controller, do:
$this->load->helper('url');
Then in your view you can do:
echo base_url();
In Google Sheets you can use =ArrayFormula(Sheet1!B2:B)on the first cell and it will populate all column contents not sure if that will work in excel
I ran into this issue when I had defined the module in the Angular controller but neglected to set the app name in my HTML file. For example:

angular.module('myApp', []).controller(...
and referenced it in my HTML file.
Oh lord, don't do it this way. HTC files are never a good idea for performance and clarity reasons, and you're using too many vendor-specific parameters for something that can easily be done cross-browser all the way back to IE6.
Apply a background image to your input field with the rounded corners and make the field's background colour transparent with border:none applied instead.

event of the relevant Worksheet.
In the Project window of the VBA editor, double-click the sheet you want to add code to and from the drop-downs at the top of the editor window, choose 'Worksheet' and 'Calculate' on the left and right respectively.
Alternatively, copy the code below into the editor of the sheet you want to use:
Private Sub Worksheet_Calculate()
If Sheets("MySheet").Range("A1").Value > 0.5 Then
MsgBox "Over 50%!", vbOKOnly
End If
End Sub
This way, every time the worksheet recalculates it will check to see if the value is > 0.5 or 50%.

Using svcutil, you can create interfaces and classes (data contracts) from the WSDL.
svcutil your.wsdl (or svcutil your.wsdl /l:vb if you want Visual Basic)
This will create a file called "your.cs" in C# (or "your.vb" in VB.NET) which contains all the necessary items.
Now, you need to create a class "MyService" which will implement the service interface (IServiceInterface) - or the several service interfaces - and this is your server instance.
Now a class by itself doesn't really help yet - you'll need to host the service somewhere. You need to either create your own ServiceHost instance which hosts the service, configure endpoints and so forth - or you can host your service inside IIS.
As of powershell 5.0, you can now use the -Depth
parameter in Get-ChildItem
!
You combine it with -Recurse
to limit the recursion.

I needed to find the position of an element inside a ListView and used this snippet that works kind of like .offset
:
const UIManager = require('NativeModules').UIManager;
const handle = React.findNodeHandle(this.refs.myElement);
UIManager.measureLayoutRelativeToParent(
handle,
(e) => {console.error(e)},
(x, y, w, h) => {
console.log('offset', x, y, w, h);
});
This assumes I had a ref='myElement'
on my component.

let save = UIAlertAction(title: "Save", style: .default) { (alertAction) in
let textField = alert.textFields![0] as UITextField
let textField2 = alert.textFields![1] as UITextField

import numpy as np

An alternative for casting the type when the array is made.
Yes, just a syntax problem. Try this instead:
if (reader["usr.ursrdaystime"] != DBNull.Value)
.Equals()
is checking to see if two Object instances are the same.
I highly recommend the book "Pro Git" by Scott Chacon. Take time and really read it, while exploring an actual git repo as you do.
HEAD: the current commit your repo is on. Most of the time HEAD
points to the latest commit in your current branch, but that doesn't have to be the case. HEAD
really just means "what is my repo currently pointing at".
In the event that the commit HEAD
refers to is not the tip of any branch, this is called a "detached head".
master: the name of the default branch that git creates for you when first creating a repo. In most cases, "master" means "the main branch". Most shops have everyone pushing to master, and master is considered the definitive view of the repo. But it's also common for release branches to be made off of master for releasing. Your local repo has its own master branch, that almost always follows the master of a remote repo.
origin: the default name that git gives to your main remote repo. Your box has its own repo, and you most likely push out to some remote repo that you and all your coworkers push to. That remote repo is almost always called origin, but it doesn't have to be.
HEAD
is an official notion in git. HEAD
always has a well-defined meaning. master
and origin
are common names usually used in git, but they don't have to be.
$result = mysql_query('SELECT * FROM Users WHERE UserName LIKE $username');
You define the string using single quotes and PHP does not parse single quote delimited strings. In order to obtain variable interpolation you will need to use double quotes OR string concatenation (or a combination there of). See http://php.net/manual/en/language.types.string.php for more information.
Also you should check that mysql_query returned a valid result resource, otherwise fetch_*, num_rows, etc will not work on the result as is not a result! IE:
$username = $_POST['username'];
$password = $_POST['password'];
$result = mysql_query('SELECT * FROM Users WHERE UserName LIKE $username');
if( $result === FALSE ) {
trigger_error('Query failed returning error: '. mysql_error(),E_USER_ERROR);
} else {
while( $row = mysql_fetch_array($result) ) {
echo $row['username'];
}
}
http://us.php.net/manual/en/function.mysql-query.php for more information.
If you include the input tag in the label tag, you don't need to use the 'for' attribute.
That said, I don't like to include the input tag in my labels because I think they're separate, not containing, entities.
Similar to Luke's answer, but with GET.
Place this php-code in a php-page, ex. getpage.php:
<?php
$_SESSION['size'] = $_GET['size'];
?>
Then call it with a jQuery script like this:
$.get( "/getpage.php?size=1");
Agree with Federico. In some cases you may run into problems using POST, although not sure if it can be browser related.
You might need a GLOBAL TEMPORARY TABLE.
In Oracle these are created once and then when invoked the data is private to your session.
Try something like this...
CREATE GLOBAL TEMPORARY TABLE temp_number
( number_column NUMBER( 10, 0 )
)
ON COMMIT DELETE ROWS;
BEGIN
INSERT INTO temp_number
( number_column )
( select distinct sgbstdn_pidm
from sgbstdn
where sgbstdn_majr_code_1 = 'HS04'
and sgbstdn_program_1 = 'HSCOMPH'
);
FOR pidms_rec IN ( SELECT number_column FROM temp_number )
LOOP
-- Do something here
NULL;
END LOOP;
END;

It is important to notice that in C# the char type is stored as Unicode UTF-16.
char c = (char)88;
or
char c = Convert.ToChar(88)
int asciiCode = (int)'A';
The literal must be ASCII equivalent. For example:
string str = "X?????????";
Console.WriteLine((int)str[0]);
Console.WriteLine((int)str[1]);
will print
X
3626
Extended ASCII ranges from 0 to 255.
Using the Symbol
char c = 'X';
Using the Unicode code
char c = '\u0058';
Using the Hexadecimal
char c = '\x0058';
The closest I could make is
select * FROM( SELECT *, ROW_NUMBER() over (ORDER BY ID ) as ct from [db].[dbo].[table] ) sub where ct > fromNumber and ct <= toNumber
Which I guess similar to select * from [db].[dbo].[table] LIMIT 0, 10
Enums are classes and should follow the conventions for classes. Instances of an enum are constants and should follow the conventions for constants. So
enum Fruit {APPLE, ORANGE, BANANA, PEAR};
There is no reason for writing FruitEnum any more than FruitClass. You are just wasting four (or five) characters that add no information.
Java itself recommends this approach and it is used in their examples.
Use dispatch groups: see here for an example, "Waiting on Groups of Queued Tasks" in the "Dispatch Queues" chapter of Apple's iOS Developer Library's Concurrency Programming Guide
Your example could look something like this:
dispatch_group_t group = dispatch_group_create();
dispatch_group_async(group,dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
// block1
NSLog(@"Block1");
[NSThread sleepForTimeInterval:5.0];
NSLog(@"Block1 End");
});
dispatch_group_async(group,dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
// block2
NSLog(@"Block2");
[NSThread sleepForTimeInterval:8.0];
NSLog(@"Block2 End");
});
dispatch_group_notify(group,dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
// block3
NSLog(@"Block3");
});
// only for non-ARC projects, handled automatically in ARC-enabled projects.
dispatch_release(group);
and could produce output like this:
2012-08-11 16:10:18.049 Dispatch[11858:1e03] Block1
2012-08-11 16:10:18.052 Dispatch[11858:1d03] Block2
2012-08-11 16:10:23.051 Dispatch[11858:1e03] Block1 End
2012-08-11 16:10:26.053 Dispatch[11858:1d03] Block2 End
2012-08-11 16:10:26.054 Dispatch[11858:1d03] Block3
Change:
<select name="select2" ...
To:
<select name="select2[]" ...
I think it's a better practice to serialize your REST call parameters, usually by JSON-encoding them:
/appointments?users=[id1,id2]
or even:
/appointments?params={users:[id1,id2]}
Then you un-encode them on the server. This is going to give you more flexibility in the long run.
Just make sure to URLEncode the params as well before you send them!

If there are duplicate keys in the first list that map to different values in the second list, like a 1-to-many relationship, but you need the values to be combined or added or something instead of updating, you can do this:
i = iter(["a", "a", "b", "c", "b"])
j = iter([1,2,3,4,5])
k = list(zip(i, j))
for (x,y) in k:
if x in d:
d[x] = d[x] + y #or whatever your function needs to be to combine them
else:
d[x] = y
In that example, d == {'a': 3, 'c': 4, 'b': 8}
You are getting this error because you are calling $apply
inside an existing digestion cycle.
The big question is: why are you calling $apply
? You shouldn't ever need to call $apply
unless you are interfacing from a non-Angular event. The existence of $apply
usually means I am doing something wrong (unless, again, the $apply happens from a non-Angular event).
If $apply
really is appropriate here, consider using a "safe apply" approach:
You can try below:
find ./ ! \( -path ./tmp -prune \) ! \( -path ./scripts -prune \) -type f -name '*_peaks.bed'
Normally, you want maximum compatibility with EditText
's normal behaviour.
So you should not use android:focusable="false"
as, yes, the view will just not be focusable anymore which looks bad. The background drawable will not show its "pressed" state anymore, for example.
What you should do instead is the following:
myEditText.setInputType(InputType.TYPE_NULL);
myEditText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// showMyDialog();
}
});
myEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
// showMyDialog();
}
}
});
By setting the input type to TYPE_NULL
, you prevent the software keyboard from popping up.
By setting the OnClickListener
and OnFocusChangeListener
, you make sure that your dialog will always open when the user clicks into the EditText
field, both when it gains focus (first click) and on subsequent clicks.
Just setting android:inputType="none"
or setInputType(InputType.TYPE_NULL)
is not always enough. For some devices, you should set android:editable="false"
in XML as well, although it is deprecated. If it does not work anymore, it will just be ignored (as all XML attributes that are not supported).
Any errors show up? This might an issue of not having set the backend. You can set it from the Python interpreter or from a config file (.matplotlib/matplotlibrc
) in you home directory.
To set the backend in code you can do
import matplotlib
matplotlib.use('Agg')
where 'Agg' is the name of the backend. Which backends are present depend on your installation and OS.
http://matplotlib.sourceforge.net/faq/installing_faq.html#backends
The current (as of version 0.20) method for changing column names after a groupby operation is to chain the rename
method. See this deprecation note in the documentation for more detail.
This is the first result in google and although the top answer works it does not really answer the question. There is a better answer here and a long discussion on github about the full functionality of passing dictionaries to the agg
method.
These answers unfortunately do not exist in the documentation but the general format for grouping, aggregating and then renaming columns uses a dictionary of dictionaries. The keys to the outer dictionary are column names that are to be aggregated. The inner dictionaries have keys that the new column names with values as the aggregating function.
Before we get there, let's create a four column DataFrame.
df = pd.DataFrame({'A' : list('wwwwxxxx'),
'B':list('yyzzyyzz'),
'C':np.random.rand(8),
'D':np.random.rand(8)})
A B C D
0 w y 0.643784 0.828486
1 w y 0.308682 0.994078
2 w z 0.518000 0.725663
3 w z 0.486656 0.259547
4 x y 0.089913 0.238452
5 x y 0.688177 0.753107
6 x z 0.955035 0.462677
7 x z 0.892066 0.368850
Let's say we want to group by columns A, B
and aggregate column C
with mean
and median
and aggregate column D
with max
. The following code would do this.
df.groupby(['A', 'B']).agg({'C':['mean', 'median'], 'D':'max'})
D C
max mean median
A B
w y 0.994078 0.476233 0.476233
z 0.725663 0.502328 0.502328
x y 0.753107 0.389045 0.389045
z 0.462677 0.923551 0.923551
This returns a DataFrame with a hierarchical index. The original question asked about renaming the columns in the same step. This is possible using a dictionary of dictionaries:
df.groupby(['A', 'B']).agg({'C':{'C_mean': 'mean', 'C_median': 'median'},
'D':{'D_max': 'max'}})
D C
D_max C_mean C_median
A B
w y 0.994078 0.476233 0.476233
z 0.725663 0.502328 0.502328
x y 0.753107 0.389045 0.389045
z 0.462677 0.923551 0.923551
This renames the columns all in one go but still leaves the hierarchical index which the top level can be dropped with df.columns = df.columns.droplevel(0)
.
If you work in MS Visual Studio just do following
Correct WSDL file like this YourSchemeFile.xsd
Use visual Studio using this great example How to generate service reference with only physical wsdl file
Notice that you have to put the path to your WSDL file manually. There is no way to use Open File dialog box out there.
__repr__
is used by the standalone Python interpreter to display a class in printable format. Example:
~> python3.5
Python 3.5.1 (v3.5.1:37a07cee5969, Dec 5 2015, 21:12:44)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> class StackOverflowDemo:
... def __init__(self):
... pass
... def __repr__(self):
... return '<StackOverflow demo object __repr__>'
...
>>> demo = StackOverflowDemo()
>>> demo
<StackOverflow demo object __repr__>
In cases where a __str__
method is not defined in the class, it will call the __repr__
function in an attempt to create a printable representation.
>>> str(demo)
'<StackOverflow demo object __repr__>'
Additionally, print()
ing the class will call __str__
by default.
Documentation, if you please
Another solution, You can just iterate over the object keys like so, Note: you must use an instantiated object with existing properties:
printTypeNames<T>(obj: T) {
const objectKeys = Object.keys(obj) as Array<keyof T>;
for (let key of objectKeys)
{
console.log('key:' + key);
}
}
You can use angularjs form state form.$submitted
.
Initially form.$submitted
value will be false
and will became true
after successful form submit.
A little stale post, but I figured what the heck. Does "whoami" meet your needs?
I just found out about it today (from the same Google search that brought me here, in fact). Windows has had a whoami tool since XP (part of an add on toolkit) and has been built-in since Vista.
whoami /groups
Lists all the AD groups for the currently logged-on user. I believe it does require you to be logged on AS that user, though, so this won't help if your use case requires the ability to run the command to look at another user.
Group names only:
whoami /groups /fo list |findstr /c:"Group Name:"
Peer dependency warnings, more often than not, can be ignored. The only time you will want to take action is if the peer dependency is missing entirely, or if the version of a peer dependency is higher than the version you have installed.
Let's take this warning as an example:
npm WARN @angular/[email protected] requires a peer of @angular/[email protected] but none is installed. You must install peer dependencies yourself.
With Angular, you would like the versions you are using to be consistent across all packages. If there are any incompatible versions, change the versions in your package.json, and run npm install
so they are all synced up. I tend to keep my versions for Angular at the latest version, but you will need to make sure your versions are consistent for whatever version of Angular you require (which may not be the most recent).
In a situation like this:
npm WARN [email protected] requires a peer of @angular/core@^2.4.0 || ^4.0.0 but none is installed. You must install peer dependencies yourself.
If you are working with a version of Angular that is higher than 4.0.0, then you will likely have no issues. Nothing to do about this one then. If you are using an Angular version under 2.4.0, then you need to bring your version up. Update the package.json, and run npm install
, or run npm install
for the specific version you need. Like this:
npm install @angular/[email protected] --save
You can leave out the --save
if you are running npm 5.0.0 or higher, that version saves the package in the dependencies section of the package.json automatically.
In this situation:
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: [email protected] (node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
You are running Windows, and fsevent requires OSX. This warning can be ignored.
Hope this helps, and have fun learning Angular!
First: Even the unique IDs generated by java UUID.randomUUID or .net GUID are not 100% unique. Especialy UUID.randomUUID is "only" a 128 bit (secure) random value. So if you reduce it to 64 bit, 32 bit, 16 bit (or even 1 bit) then it becomes simply less unique.
So it is at least a risk based decisions, how long your uuid must be.
Second: I assume that when you talk about "only 8 characters" you mean a String of 8 normal printable characters.
If you want a unique string with length 8 printable characters you could use a base64 encoding. This means 6bit per char, so you get 48bit in total (possible not very unique - but maybe it is ok for you application)
So the way is simple: create a 6 byte random array
SecureRandom rand;
// ...
byte[] randomBytes = new byte[16];
rand.nextBytes(randomBytes);
And then transform it to a Base64 String, for example by org.apache.commons.codec.binary.Base64
BTW: it depends on your application if there is a better way to create "uuid" then by random. (If you create a the UUIDs only once per second, then it is a good idea to add a time stamp) (By the way: if you combine (xor) two random values, the result is always at least as random as the most random of the both).
