What are you trying to accomplish? You can access characters in a string just like an array:
$s = 'abcd';
echo $s[0];
prints 'a'
Since Java 8, we could use streams instead of for loops. Also, it might be apropriate to return an Optional if the enum does not have an instance with such a name.
I have come up with the following three alternatives on how to look up an enum:
private enum Test {
TEST1, TEST2;
public Test fromNameOrThrowException(String name) {
return Arrays.stream(values())
.filter(e -> e.name().equals(name))
.findFirst()
.orElseThrow(() -> new IllegalArgumentException("No enum with name " + name));
}
public Test fromNameOrNull(String name) {
return Arrays.stream(values()).filter(e -> e.name().equals(name)).findFirst().orElse(null);
}
public Optional<Test> fromName(String name) {
return Arrays.stream(values()).filter(e -> e.name().equals(name)).findFirst();
}
}
Beautiful Soup handles entity conversion. In Beautiful Soup 3, you'll need to specify the convertEntities
argument to the BeautifulSoup
constructor (see the 'Entity Conversion' section of the archived docs). In Beautiful Soup 4, entities get decoded automatically.
>>> from BeautifulSoup import BeautifulSoup
>>> BeautifulSoup("<p>£682m</p>",
... convertEntities=BeautifulSoup.HTML_ENTITIES)
<p>£682m</p>
>>> from bs4 import BeautifulSoup
>>> BeautifulSoup("<p>£682m</p>")
<html><body><p>£682m</p></body></html>
Another solution is passing the read function to the constructor of Readable (cf doc stream readeable options)
var s = new Readable({read(size) {
this.push("your string here")
this.push(null)
}});
you can after use s.pipe for exemple
I've built systems before that use the following:
In the systems I've built admins were under instruction to react to ERRORs. On the other hand we would watch for WARNINGS and determine for each case whether any system changes, reconfigurations etc. were required.
Here the trait fully emulates running controller by laravel router (including support of middlewares and dependency injection). Tested only with 5.4 version
<?php
namespace App\Traits;
use Illuminate\Pipeline\Pipeline;
use Illuminate\Routing\ControllerDispatcher;
use Illuminate\Routing\MiddlewareNameResolver;
use Illuminate\Routing\SortedMiddleware;
trait RunsAnotherController
{
public function runController($controller, $method = 'index')
{
$middleware = $this->gatherControllerMiddleware($controller, $method);
$middleware = $this->sortMiddleware($middleware);
return $response = (new Pipeline(app()))
->send(request())
->through($middleware)
->then(function ($request) use ($controller, $method) {
return app('router')->prepareResponse(
$request, (new ControllerDispatcher(app()))->dispatch(
app('router')->current(), $controller, $method
)
);
});
}
protected function gatherControllerMiddleware($controller, $method)
{
return collect($this->controllerMidlleware($controller, $method))->map(function ($name) {
return (array)MiddlewareNameResolver::resolve($name, app('router')->getMiddleware(), app('router')->getMiddlewareGroups());
})->flatten();
}
protected function controllerMidlleware($controller, $method)
{
return ControllerDispatcher::getMiddleware(
$controller, $method
);
}
protected function sortMiddleware($middleware)
{
return (new SortedMiddleware(app('router')->middlewarePriority, $middleware))->all();
}
}
Then just add it to your class and run the controller. Note, that dependency injection will be assigned with your current route.
class CustomController extends Controller {
use RunsAnotherController;
public function someAction()
{
$controller = app()->make('App\Http\Controllers\AnotherController');
return $this->runController($controller, 'doSomething');
}
}

Use this code to disable delete button in gridview from code behind.
protected void gv_Document_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
((LinkButton)e.Row.Cells[7].Controls[0]).Visible = false;
}
}
One additional reason to use a typedef for the superclass is when you are using complex templates in the object's inheritance.
For instance:
template <typename T, size_t C, typename U>
class A
{ ... };
template <typename T>
class B : public A<T,99,T>
{ ... };
In class B it would be ideal to have a typedef for A otherwise you would be stuck repeating it everywhere you wanted to reference A's members.
In these cases it can work with multiple inheritance too, but you wouldn't have a typedef named 'super', it would be called 'base_A_t' or something like that.

I don't program Scala, but I use another language with implicit returns (Ruby). You have code after your if (elem.isEmpty)
block -- the last line of code is what's returned, which is why you're not getting what you're expecting.
EDIT: Here's a simpler way to write your function too. Just use the boolean value of isEmpty and count to return true or false automatically:
def balanceMain(elem: List[Char]): Boolean =
{
elem.isEmpty && count == 0
}
tv.setText(Integer.toString(intValue))
My guess is that rake
is a batch program. When you invoke it without call
, then control doesn't return to your build.bat
. Try:
@echo off
cls
CALL rake
pause
A[A==NDV]=numpy.nan
A==NDV will produce a boolean array that can be used as an index for A
var tooLong = document.getElementById("longText").value;
if (tooLong.length() > 18){
$('#longText').css('text-overflow', 'ellipsis');
}
Make sure to balance the risk that fresh statistics cause undesirable changes to query plans against the risk that stale statistics can themselves cause query plans to change.
Imagine you have a bug database with a table ISSUE and a column CREATE_DATE where the values in the column increase more or less monotonically. Now, assume that there is a histogram on this column that tells Oracle that the values for this column are uniformly distributed between January 1, 2008 and September 17, 2008. This makes it possible for the optimizer to reasonably estimate the number of rows that would be returned if you were looking for all issues created last week (i.e. September 7 - 13). If the application continues to be used and the statistics are never updated, though, this histogram will be less and less accurate. So the optimizer will expect queries for "issues created last week" to be less and less accurate over time and may eventually cause Oracle to change the query plan negatively.
You need to write a controller with ng-change
function in scope. In ng-change
callback you do a call to server and update completions. Here is a stub (without $http
as this is a plunk):

<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.js"></script>

</body>
</html>
JS
angular.module('plunker', ['ui.bootstrap']);
function TypeaheadCtrl($scope) {
$scope.selected = undefined;
$scope.states = [];
$scope.onedit = function(){
$scope.states = [];
for(var i = 0; i < Math.floor((Math.random()*10)+1); i++){
var value = "";
for(var j = 0; j < i; j++){
value += j;
}
$scope.states.push(value);
}
}
}
I have found that Android Studio gives me a warning that getColor()
is deprecated when trying to do this:
Button11.setBackgroundColor(getResources().getColor(R.color.red))
So I found doing the method below to be the simple, up-to-date solution:
Button11.setBackgroundColor(ContextCompat.getColor(context, R.color.red))
You want to avoid hard-coding in the color argument, as it is considered bad code style.
Edit: After using setBackgroundColor()
with my own button, I saw that the internal button padding expanded. I couldn't find any way of changing it back to having both height and width set to "wrap_content". Maybe its a bug.
Andrey Tarasevich provides the following explanation:
[Minor changes to formatting made. Parenthetical annotations added in square brackets []
].
The whole idea of using 'do/while' version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the use of function-style macros uniform with the use of ordinary functions in all contexts.
Consider the following code sketch:
if (<condition>) foo(a); else bar(a);
where
foo
andbar
are ordinary functions. Now imagine that you'd like to replace functionfoo
with a macro of the above nature [namedCALL_FUNCS
]:if (<condition>) CALL_FUNCS(a); else bar(a);
Now, if your macro is defined in accordance with the second approach (just
{
and}
) the code will no longer compile, because the 'true' branch ofif
is now represented by a compound statement. And when you put a;
after this compound statement, you finished the wholeif
statement, thus orphaning theelse
branch (hence the compilation error).One way to correct this problem is to remember not to put
;
after macro "invocations":if (<condition>) CALL_FUNCS(a) else bar(a);
This will compile and work as expected, but this is not uniform. The more elegant solution is to make sure that macro expand into a regular statement, not into a compound one. One way to achieve that is to define the macro as follows:
#define CALL_FUNCS(x) \ do { \ func1(x); \ func2(x); \ func3(x); \ } while (0)
Now this code:
if (<condition>) CALL_FUNCS(a); else bar(a);
will compile without any problems.
However, note the small but important difference between my definition of
CALL_FUNCS
and the first version in your message. I didn't put a;
after} while (0)
. Putting a;
at the end of that definition would immediately defeat the entire point of using 'do/while' and make that macro pretty much equivalent to the compound-statement version.I don't know why the author of the code you quoted in your original message put this
;
afterwhile (0)
. In this form both variants are equivalent. The whole idea behind using 'do/while' version is not to include this final;
into the macro (for the reasons that I explained above).
hg rollback
is what you want.
In TortoiseHg, the hg rollback
is accomplished in the commit dialog. Open the commit dialog and select "Undo".
You can also use EXIT_SUCCESS
instead of return 0;
. The macro EXIT_SUCCESS
is actually defined as zero, but makes your program more readable.
I recommend XML reader/writer class for files because it is easily serialized.
Serialization (known as pickling in python) is an easy way to convert an object to a binary representation that can then be e.g. written to disk or sent over a wire.
It's useful e.g. for easy saving of settings to a file.
You can serialize your own classes if you mark them with
[Serializable]
attribute. This serializes all members of a class, except those marked as[NonSerialized]
.
The following is code to show you how to do this:
using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
namespace ConfigTest
{ [ Serializable() ]
public class ConfigManager
{
private string windowTitle = "Corp";
private string printTitle = "Inventory";
public string WindowTitle
{
get
{
return windowTitle;
}
set
{
windowTitle = value;
}
}
public string PrintTitle
{
get
{
return printTitle;
}
set
{
printTitle = value;
}
}
}
}
You then, in maybe a ConfigForm, call your ConfigManager class and Serialize it!
public ConfigForm()
{
InitializeComponent();
cm = new ConfigManager();
ser = new XmlSerializer(typeof(ConfigManager));
LoadConfig();
}
private void LoadConfig()
{
try
{
if (File.Exists(filepath))
{
FileStream fs = new FileStream(filepath, FileMode.Open);
cm = (ConfigManager)ser.Deserialize(fs);
fs.Close();
}
else
{
MessageBox.Show("Could not find User Configuration File\n\nCreating new file...", "User Config Not Found");
FileStream fs = new FileStream(filepath, FileMode.CreateNew);
TextWriter tw = new StreamWriter(fs);
ser.Serialize(tw, cm);
tw.Close();
fs.Close();
}
setupControlsFromConfig();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
After it has been serialized, you can then call the parameters of your config file using cm.WindowTitle, etc.
After doing some testing, building upon the suggestions in the previous answers, there seem to be two usable solutions.
Method 1 is fastest, but less powerful in terms of matching more complex patterns.
Method 2 is more flexible, but slower.
Method 1 - fastest
I've tested this method on a table with 1 million rows.
It seems to be 3.8 times faster than the regex solutions.
The 0-replacement solves the issue that 0 is mapped to a space, and does not seem to slow down the query.
SELECT *
FROM <table>
WHERE TRANSLATE(replace(<char_column>,'0',''),'0123456789',' ') IS NOT NULL;
Method 2 - slower, but more flexible
I've compared the speed of putting the negation inside or outside the regex statement. Both are equally slower than the translate-solution. As a result, @ciuly's approach seems most sensible when using regex.
SELECT *
FROM <table>
WHERE NOT REGEXP_LIKE(<char_column>, '^[0-9]+$');
This uses rand with a seed like one of the other answers, but it is not necessary to provide a seed on every call. Providing it on the first call is sufficient.
This is my modified code.
IF EXISTS (SELECT * FROM sys.objects WHERE type = 'P' AND object_id = OBJECT_ID(N'usp_generateIdentifier'))
DROP PROCEDURE usp_generateIdentifier
GO
create procedure usp_generateIdentifier
@minLen int = 1
, @maxLen int = 256
, @seed int output
, @string varchar(8000) output
as
begin
set nocount on;
declare @length int;
declare @alpha varchar(8000)
, @digit varchar(8000)
, @specials varchar(8000)
, @first varchar(8000)
select @alpha = 'qwertyuiopasdfghjklzxcvbnm'
, @digit = '1234567890'
, @specials = '_@#$&'
select @first = @alpha + '_@';
-- Establish our rand seed and store a new seed for next time
set @seed = (rand(@seed)*2147483647);
select @length = @minLen + rand() * (@maxLen-@minLen);
--print @length
declare @dice int;
select @dice = rand() * len(@first);
select @string = substring(@first, @dice, 1);
while 0 < @length
begin
select @dice = rand() * 100;
if (@dice < 10) -- 10% special chars
begin
select @dice = rand() * len(@specials)+1;
select @string = @string + substring(@specials, @dice, 1);
end
else if (@dice < 10+10) -- 10% digits
begin
select @dice = rand() * len(@digit)+1;
select @string = @string + substring(@digit, @dice, 1);
end
else -- rest 80% alpha
begin
select @dice = rand() * len(@alpha)+1;
select @string = @string + substring(@alpha, @dice, 1);
end
select @length = @length - 1;
end
end

Using this.props.children
is the idiomatic way to pass instantiated components to a react component
const Label = props => <span>{props.children}</span>
const Tab = props => <div>{props.children}</div>
const Page = () => <Tab><Label>Foo</Label></Tab>
When you pass a component as a parameter directly, you pass it uninstantiated and instantiate it by retrieving it from the props. This is an idiomatic way of passing down component classes which will then be instantiated by the components down the tree (e.g. if a component uses custom styles on a tag, but it wants to let the consumer choose whether that tag is a div
or span
):
const Label = props => <span>{props.children}</span>
const Button = props => {
const Inner = props.inner; // Note: variable name _must_ start with a capital letter
return <button><Inner>Foo</Inner></button>
}
const Page = () => <Button inner={Label}/>
If what you want to do is to pass a children-like parameter as a prop, you can do that:
const Label = props => <span>{props.content}</span>
const Tab = props => <div>{props.content}</div>
const Page = () => <Tab content={<Label content='Foo' />} />
After all, properties in React are just regular JavaScript object properties and can hold any value - be it a string, function or a complex object.
Another answer based on extensions (boy do I miss this in Java):
extension NSData {
func toUtf8() -> String? {
return String(data: self, encoding: NSUTF8StringEncoding)
}
}
Then you can use it:
let data : NSData = getDataFromEpicServer()
let string : String? = data.toUtf8()
Note that the string is optional, the initial NSData
may be unconvertible to Utf8.
WebElement element = driver.findElement(By.id("inst_state"));
Select s = new Select(element);
List <WebElement> elementcount = s.getOptions();
System.out.println(elementcount.size());
for(int i=0 ;i<elementcount.size();i++)
{
String value = elementcount.get(i).getText();
System.out.println(value);
}
You should use
$this->db->where('$accommodation >=', minvalue);
$this->db->where('$accommodation <=', maxvalue);
I'm not sure of syntax, so I beg your pardon if it's not correct.
Anyway BETWEEN
is implemented using >=min && <=max.
This is the meaning of my example.
EDITED:
Looking at this link I think you could write:
$this->db->where("$accommodation BETWEEN $minvalue AND $maxvalue");
I'm using Rails + Cucumber + Selenium Webdriver + PhantomJS, and I've been using a monkey-patched version of Selenium Webdriver, which keeps PhantomJS browser open between test runs. See this blog post: http://blog.sharetribe.com/2014/04/07/faster-cucumber-startup-keep-phantomjs-browser-open-between-tests/

1- There is no way to actually destroy an object in javascript, but using delete
, we could remove a reference from an object:
var obj = {};
obj.mypointer = null;
delete obj.mypointer;
2- The important point about the delete
keyword is that it does not actually destroy the object BUT if only after deleting that reference to the object, there is no other reference left in the memory pointed to the same object, that object would be marked as collectible. The delete
keyword deletes the reference but doesn't GC the actual object. it means if you have several references of the same object, the object will be collected just after you delete all the pointed references.
3- there are also some tricks and workarounds that could help us out, when we want to make sure we do not leave any memory leaks behind. for instance if you have an array consisting several objects, without any other pointed reference to those objects, if you recreate the array all those objects would be killed. For instance if you have var array = [{}, {}]
overriding the value of the array like array = []
would remove the references to the two objects inside the array and those two objects would be marked as collectible.
4- for your solution the easiest way is just this:
var storage = {};
storage.instance = new Class();
//since 'storage.instance' is your only reference to the object, whenever you wanted to destroy do this:
storage.instance = null;
// OR
delete storage.instance;
As mentioned above, either setting storage.instance = null
or delete storage.instance
would suffice to remove the reference to the object and allow it to be cleaned up by the GC. The difference is that if you set it to null
then the storage object still has a property called instance (with the value null). If you delete storage.instance
then the storage object no longer has a property named instance.
and WHAT ABOUT destroy method ??
the paradoxical point here is if you use instance.destroy
in the destroy function you have no access to the actual instance
pointer, and it won't let you delete it.
The only way is to pass the reference to the destroy function and then delete it:
// Class constructor
var Class = function () {
this.destroy = function (baseObject, refName) {
delete baseObject[refName];
};
};
// instanciate
var storage = {};
storage.instance = new Class();
storage.instance.destroy(object, "instance");
console.log(storage.instance); // now it is undefined
BUT if I were you I would simply stick to the first solution and delete the object like this:
storage.instance = null;
// OR
delete storage.instance;
WOW it was too much :)
Here's what I did based on
a) @Espo 's comments and
b) the fact that I only had Windows Task Manager to play with....
I logged onto the host machine, opened Task Manager and used the view menu to add the PID column to the Processes tab.
I wrote down (yes, with paper and a pen) the PID's for each and every instance of the vmware-wmx.exe process that was running on the box.
Using the VMWare console, I suspended the errant virtual machine.
When I resumed it, I could then identify the vmware-vmx process that corresponded to my machine and could kill it.
There doesn't seem to have been any ill effects so far.

Enable cross-origin requests in ASP.NET Web API click for more info
Enable CORS in the WebService app. First, add the CORS NuGet package. In Visual Studio, from the Tools menu, select NuGet Package Manager, then select Package Manager Console. In the Package Manager Console window, type the following command:
Install-Package Microsoft.AspNet.WebApi.Cors
This command installs the latest package and updates all dependencies, including the core Web API libraries. Use the -Version flag to target a specific version. The CORS package requires Web API 2.0 or later.
Open the file App_Start/WebApiConfig.cs. Add the following code to the WebApiConfig.Register method:
using System.Web.Http;
namespace WebService
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// New code
config.EnableCors();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
}
Next, add the [EnableCors] attribute to your controller/ controller methods
using System.Net.Http;
using System.Web.Http;
using System.Web.Http.Cors;
namespace WebService.Controllers
{
[EnableCors(origins: "http://mywebclient.azurewebsites.net", headers: "*", methods: "*")]
public class TestController : ApiController
{
// Controller methods not shown...
}
}
This would work
setInterval(function(){$("#myButtonId").click();}, 1000);
You have the :nth-child()
pseudo-class:
table tr:nth-child(odd) td{
...
}
table tr:nth-child(even) td{
...
}
In the early days of :nth-child()
its browser support was kind of poor. That's why setting class="odd"
became such a common technique. In late 2013 I'm glad to say that IE6 and IE7 are finally dead (or sick enough to stop caring) but IE8 is still around — thankfully, it's the only exception.
This works for me
public string[] GetGroupNames(string domainName, string userName)
{
List<string> result = new List<string>();
using (PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, domainName))
{
using (PrincipalSearchResult<Principal> src = UserPrincipal.FindByIdentity(principalContext, userName).GetGroups())
{
src.ToList().ForEach(sr => result.Add(sr.SamAccountName));
}
}
return result.ToArray();
}
There are couple of good free service that let you do the same. Ideal for showing something quickly for testing:
Edits:
<input type="text" name="MobileNumber" id="MobileNumber" maxlength="10" onkeypress="checkNumber(event);" placeholder="MobileNumber">
<script>
function checkNumber(key) {
console.log(key);
var inputNumber = document.querySelector("#MobileNumber").value;
if(key.key >= 0 && key.key <= 9) {
inputNumber += key.key;
}
else {
key.preventDefault();
}
}
</script>
You have an incredible number of choices to achieve delegates in C++. Here are the ones that came to my mind.
Option 1 : functors:
A function object may be created by implementing operator()
struct Functor
{
// Normal class/struct members
int operator()(double d) // Arbitrary return types and parameter list
{
return (int) d + 1;
}
};
// Use:
Functor f;
int i = f(3.14);
Option 2: lambda expressions (C++11 only)
// Syntax is roughly: [capture](parameter list) -> return type {block}
// Some shortcuts exist
auto func = [](int i) -> double { return 2*i/1.15; };
double d = func(1);
Option 3: function pointers
int f(double d) { ... }
typedef int (*MyFuncT) (double d);
MyFuncT fp = &f;
int a = fp(3.14);
Option 4: pointer to member functions (fastest solution)
See Fast C++ Delegate (on The Code Project).
struct DelegateList
{
int f1(double d) { }
int f2(double d) { }
};
typedef int (DelegateList::* DelegateType)(double d);
DelegateType d = &DelegateList::f1;
DelegateList list;
int a = (list.*d)(3.14);
Option 5: std::function
(or boost::function
if your standard library doesn't support it). It is slower, but it is the most flexible.
#include <functional>
std::function<int(double)> f = [can be set to about anything in this answer]
// Usually more useful as a parameter to another functions
Option 6: binding (using std::bind)
Allows setting some parameters in advance, convenient to call a member function for instance.
struct MyClass
{
int DoStuff(double d); // actually a DoStuff(MyClass* this, double d)
};
std::function<int(double d)> f = std::bind(&MyClass::DoStuff, this, std::placeholders::_1);
// auto f = std::bind(...); in C++11
Option 7: templates
Accept anything as long as it matches the argument list.
template <class FunctionT>
int DoSomething(FunctionT func)
{
return func(3.14);
}
The title
attribute displays a tooltip when the mouse is hovering the element. While this is a great addition, it doesn't help people who cannot use the mouse (due to mobility disabilities) or people who can't see this tooltip (e.g.: people with visual disabilities or people who use a screen reader).
As such, the mindful approach here would be to serve all users. I would add both title
and aria-label
attributes (serving different types of users and different types of usage of the web).
Here's a good article that explains aria-label
in depth
If you override a parent method in its child, child objects will always use the overridden version. But; you can use the keyword super
to call the parent method, inside the body of the child method.
public class PolyTest{
public static void main(String args[]){
new Child().foo();
}
}
class Parent{
public void foo(){
System.out.println("I'm the parent.");
}
}
class Child extends Parent{
@Override
public void foo(){
//super.foo();
System.out.println("I'm the child.");
}

You should look for the concept of Polymorphism.
#Check code and apply in your Program: #Input= 'pppmm'
s = 'ppppmm'
s = ''.join(set(s))
print(s)

Already good answer there. Just add a benchmark result for StringBuffer and StringBuild performance difference use new instance in loop or use setLength(0) in loop.
The summary is: In a large loop
Very simple benchmark (I just manually changed the code and do different test ):
public class StringBuilderSpeed {
public static final char ch[] = new char[]{'a','b','c','d','e','f','g','h','i'};
public static void main(String a[]){
int loopTime = 99999999;
long startTime = System.currentTimeMillis();
StringBuilder sb = new StringBuilder();
for(int i = 0 ; i < loopTime; i++){
for(char c : ch){
sb.append(c);
}
sb.setLength(0);
}
long endTime = System.currentTimeMillis();
System.out.println("Time cost: " + (endTime - startTime));
}
}
New StringBuilder instance in loop: Time cost: 3693, 3862, 3624, 3742
StringBuilder setLength: Time cost: 3465, 3421, 3557, 3408
New StringBuffer instance in loop: Time cost: 8327, 8324, 8284
StringBuffer setLength Time cost: 22878, 23017, 22894
Again StringBuilder setLength to ensure not my labtop got some issue to use such long for StringBuffer setLength :-) Time cost: 3448
Try it like this:
Sub testIt()
Dim r As Long, endRow as Long, pasteRowIndex As Long
endRow = 10 ' of course it's best to retrieve the last used row number via a function
pasteRowIndex = 1
For r = 1 To endRow 'Loop through sheet1 and search for your criteria
If Cells(r, Columns("B").Column).Value = "YourCriteria" Then 'Found
'Copy the current row
Rows(r).Select
Selection.Copy
'Switch to the sheet where you want to paste it & paste
Sheets("Sheet2").Select
Rows(pasteRowIndex).Select
ActiveSheet.Paste
'Next time you find a match, it will be pasted in a new row
pasteRowIndex = pasteRowIndex + 1
'Switch back to your table & continue to search for your criteria
Sheets("Sheet1").Select
End If
Next r
End Sub
We often run into this where we want to include a the index value and first and last indicators in a list without creating a new object. This allows you to know the position of the item in your list, enumeration, etc. without having to modify the existing class and then knowing whether you're at the first item in the list or the last.
foreach (Item item in this.Items
.Select((x, i) => {
x.ListIndex = i;
x.IsFirst = i == 0;
x.IsLast = i == this.Items.Count-1;
return x;
}))
You can simply extend any class by using:
public abstract class IteratorExtender {
public int ListIndex { get; set; }
public bool IsFirst { get; set; }
public bool IsLast { get; set; }
}
public class Item : IteratorExtender {}
Here is a method I used and worked for me
public static String toSql(Session session, Criteria criteria){
String sql="";
Object[] parameters = null;
try{
CriteriaImpl c = (CriteriaImpl) criteria;
SessionImpl s = (SessionImpl)c.getSession();
SessionFactoryImplementor factory = (SessionFactoryImplementor)s.getSessionFactory();
String[] implementors = factory.getImplementors( c.getEntityOrClassName() );
CriteriaLoader loader = new CriteriaLoader((OuterJoinLoadable)factory.getEntityPersister(implementors[0]), factory, c, implementors[0], s.getEnabledFilters());
Field f = OuterJoinLoader.class.getDeclaredField("sql");
f.setAccessible(true);
sql = (String)f.get(loader);
Field fp = CriteriaLoader.class.getDeclaredField("traslator");
fp.setAccessible(true);
CriteriaQueryTranslator translator = (CriteriaQueryTranslator) fp.get(loader);
parameters = translator.getQueryParameters().getPositionalParameterValues();
}
catch(Exception e){
throw new RuntimeException(e);
}
if (sql !=null){
int fromPosition = sql.indexOf(" from ");
sql = "SELECT * "+ sql.substring(fromPosition);
if (parameters!=null && parameters.length>0){
for (Object val : parameters) {
String value="%";
if(val instanceof Boolean){
value = ((Boolean)val)?"1":"0";
}else if (val instanceof String){
value = "'"+val+"'";
}
sql = sql.replaceFirst("\\?", value);
}
}
}
return sql.replaceAll("left outer join", "\nleft outer join").replace(" and ", "\nand ").replace(" on ", "\non ");
}

C++ programs are built in two phases
Static library (.lib) is just a bundle of .obj files and therefore isn't a complete program. It hasn't undergone the second (linking) phase of building a program. Dlls, on the other hand, are like exe's and therefore are complete programs.
If you build a static library, it isn't linked yet and therefore consumers of your static library will have to use the same compiler that you used (if you used g++, they will have to use g++).
If instead you built a dll (and built it correctly), you have built a complete program that all consumers can use, no matter which compiler they are using. There are several restrictions though, on exporting from a dll, if cross compiler compatibility is desired.
Applying the full_extent()
function in an answer by @Joe 3 years later from here, you can get exactly what the OP was looking for. Alternatively, you can use Axes.get_tightbbox()
which gives a little tighter bounding box
import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np
from matplotlib.transforms import Bbox
def full_extent(ax, pad=0.0):
"""Get the full extent of an axes, including axes labels, tick labels, and
titles."""
# For text objects, we need to draw the figure first, otherwise the extents
# are undefined.
ax.figure.canvas.draw()
items = ax.get_xticklabels() + ax.get_yticklabels()
# items += [ax, ax.title, ax.xaxis.label, ax.yaxis.label]
items += [ax, ax.title]
bbox = Bbox.union([item.get_window_extent() for item in items])
return bbox.expanded(1.0 + pad, 1.0 + pad)
# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')
ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')
# Save the full figure...
fig.savefig('full_figure.png')
# Save just the portion _inside_ the second axis's boundaries
extent = full_extent(ax2).transformed(fig.dpi_scale_trans.inverted())
# Alternatively,
# extent = ax.get_tightbbox(fig.canvas.renderer).transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

You need to put % name
straight after the string:
f = open('%s.csv' % name, 'wb')
The reason your code doesn't work is because you are trying to %
a file, which isn't string formatting, and is also invalid.
It's only for test, you can do it in google chrome: navigate to: chrome://flags/#unsafely-treat-insecure-origin-as-secure then you'll see: Type address you want to allow, then enable and relaunch your browser.
Since Magic Quotes is now off by default (and scheduled for removal), you can just remove that function call from your code.
One way is to leave a raw_input()
at the end so the script waits for you to press Enter before it terminates.
If you just want to print the rounded result out, you can use the f-strings introduced since Python 3.6. The syntax is the same as str.format()
's format string syntax, except you put a f
in front of the literal string, and you put the variables directly in the string, within the curly braces.
.2f
indicates rounding to two decimal places:
number = 3.1415926
print(f"The number rounded to two decimal places is {number:.2f}")
Output:
The number rounded to two decimal places is 3.14

this will give you a script that drops and recreates all your tables without the need to worry about debugging or whether you've included everything. While this performs more than just a truncate, the results are the same. Just keep in mind that your auto-incrementing primary keys will start at 0, as opposed to truncated tables which will remember the last value assigned. You can also execute this from code if you don't have access to Management studio on your PreProd or Production environments.

From the docs, the recommended way of getting a timezone aware datetime object from seconds since epoch is:
from datetime import datetime, timezone
datetime.fromtimestamp(timestamp, timezone.utc)
from datetime import datetime
import pytz
datetime.fromtimestamp(timestamp, pytz.utc)
One way I've seen is to pass a mutable object, such as a list or a dictionary, to the thread's constructor, along with a an index or other identifier of some sort. The thread can then store its results in its dedicated slot in that object. For example:
def foo(bar, result, index):
print 'hello {0}'.format(bar)
result[index] = "foo"
from threading import Thread
threads = [None] * 10
results = [None] * 10
for i in range(len(threads)):
threads[i] = Thread(target=foo, args=('world!', results, i))
threads[i].start()
# do some other stuff
for i in range(len(threads)):
threads[i].join()
print " ".join(results) # what sound does a metasyntactic locomotive make?
If you really want join()
to return the return value of the called function, you can do this with a Thread
subclass like the following:
from threading import Thread
def foo(bar):
print 'hello {0}'.format(bar)
return "foo"
class ThreadWithReturnValue(Thread):
def __init__(self, group=None, target=None, name=None,
args=(), kwargs={}, Verbose=None):
Thread.__init__(self, group, target, name, args, kwargs, Verbose)
self._return = None
def run(self):
if self._Thread__target is not None:
self._return = self._Thread__target(*self._Thread__args,
**self._Thread__kwargs)
def join(self):
Thread.join(self)
return self._return
twrv = ThreadWithReturnValue(target=foo, args=('world!',))
twrv.start()
print twrv.join() # prints foo
That gets a little hairy because of some name mangling, and it accesses "private" data structures that are specific to Thread
implementation... but it works.
For python3
class ThreadWithReturnValue(Thread):
def __init__(self, group=None, target=None, name=None,
args=(), kwargs={}, Verbose=None):
Thread.__init__(self, group, target, name, args, kwargs)
self._return = None
def run(self):
print(type(self._target))
if self._target is not None:
self._return = self._target(*self._args,
**self._kwargs)
def join(self, *args):
Thread.join(self, *args)
return self._return

A simple way to do this is
var jsonArray = store.data.items
So if your JSON store is
[{"text": "ABC"}, {"text": "DEF"},{"text": "GHI"},{"text": "JKL"}]
Then you can retreive "DEF" as
jsonArray[1].data.text
In the following code, I noticed that it converts each and every character into an array item.
var jsonData = Ext.encode(Ext.pluck(store.data.items, 'data'));

foreach (var x in result)
{
Console.WriteLine("Value: " + x.Key + " Count: " + x.Value);

Although I take the risk of not being popular I say they are not useful nowadays.
I think they were well intended and useful in the past when for example DELETE told the server to delete the resource found at supplied URL and PUT (with its sibling PATCH) told the server to do update in an idempotent manner.
Things evolved and URLs became virtual (see url rewriting for example) making resources lose their initial meaning of real folder/subforder/file and so, CRUD action verbs covered by HTTP protocol methods (GET, POST, PUT/PATCH, DELETE) lost track.
Let's take an example:
On the left side is not written the HTTP method, essentially it doesn't matter (POST and GET are enough) and on the right side appropriate HTTP methods are used.
Right side looks elegant, clean and professional. Imagine now you have to maintain a code that's been using the elegant API and you have to search where deletion call is done. You'll search for "api/entity" and among results you'll have to see which one is doing DELETE. Or even worse, you have a junior programmer which by mistake switched PUT with DELETE and as URL is the same shit happened.
In my opinion putting the action verb in the URL has advantages over using the appropriate HTTP method for that action even if it's not so elegant. If you want to see where delete call is made you just have to search for "api/entity/delete" and you'll find it straight away.
Building an API without the whole HTTP array of methods makes it easier to be consumed and maintained afterwards
Just make sure put single space before and after "and" Keyword..

I got same exception while running gradle build for my android project.
Caused by: java.lang.IllegalStateException: Failed to find target with hash string 'android-27'
This issue related to android SDK version enable for your Android Studio. Please find the solution of this problem from attached screen.
You can try with the following:
new_string = your_string.split(',').pop().trim();
This is how it works:
split(',')
creates an array made of the different parts of your_string
(e.g. if the string is "'SELECT___100E___7',24"
, the array would be ["'SELECT___100E___7'", "24"]
).
pop()
gets the last element of the array(in the example, it would be "24"
).
This would already be enough, but in case there might be some spaces (not in the case of the OP, but more in general), we could have:
trim()
that would remove the spaces around the string (in case it would be " 24 "
, it would become simply "24"
)It's a simple solution and surely easier than a regexp.

As said before, with JPA, in order to have the chance to have extra columns, you need to use two OneToMany associations, instead of a single ManyToMany relationship. You can also add a column with autogenerated values; this way, it can work as the primary key of the table, if useful.
For instance, the implementation code of the extra class should look like that:
@Entity
@Table(name = "USER_SERVICES")
public class UserService{
// example of auto-generated ID
@Id
@Column(name = "USER_SERVICES_ID", nullable = false)
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long userServiceID;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "USER_ID")
private User user;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "SERVICE_ID")
private Service service;
// example of extra column
@Column(name="VISIBILITY")
private boolean visibility;
public long getUserServiceID() {
return userServiceID;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public Service getService() {
return service;
}
public void setService(Service service) {
this.service = service;
}
public boolean getVisibility() {
return visibility;
}
public void setVisibility(boolean visibility) {
this.visibility = visibility;
}
}
I got this from Secure Code Guideline for Java
The examples in this section use java.util.Date extensively as it is an example of a mutable API class. In an application, it would be preferable to use the new Java Date and Time API (java.time.*) which has been designed to be immutable.
I would do something like this:
Select count(*), productid
from products
where keyword = '$keyword'
group by productid
that will give you a list like
count(*) productid
----------------------
5 12345
3 93884
9 93493
This allows you to see how many of each distinct productid ID is associated with the keyword.

There is an exception (I'm using SQL 2014) when you are only using Insert/Update/Delete on Declared-Tables. These Insert/Update/Delete statements cannot contain an OUTPUT statement. The other restriction is that you are not allowed to do a MERGE, even into a Declared-Table. I broke up my Merge statements, that didn't work, into Insert/Update/Delete statements that did work.
The reason I didn't convert it to a stored-procedure is that the table-function was faster (even without the MERGE) than the stored-procedure. This is despite the stored-procedure allowing me to use Temp-Tables that have statistics. I needed the table-function to be very fast, since it is called 20-K times/day. This table function never updates the database.
I also noticed that the NewId() and RAND() SQL functions are not allowed in a function.

First Program with comments
#include <stdio.h>
int main(){
int *ptr; //Create a pointer that points to random memory address
*ptr = 20; //Dereference that pointer,
// and assign a value to random memory address.
//Depending on external (not inside your program) state
// this will either crash or SILENTLY CORRUPT another
// data structure in your program.
printf("%d", *ptr); //Print contents of same random memory address
// May or may not crash, depending on who owns this address
return 0;
}
Second Program with comments
#include <stdio.h>
int main(){
int *ptr; //Create pointer to random memory address
int q = 50; //Create local variable with contents int 50
ptr = &q; //Update address targeted by above created pointer to point
// to local variable your program properly created
printf("%d", *ptr); //Happily print the contents of said local variable (q)
return 0;
}
The key is you cannot use a pointer until you know it is assigned to an address that you yourself have managed, either by pointing it at another variable you created or to the result of a malloc call.
Using it before is creating code that depends on uninitialized memory which will at best crash but at worst work sometimes, because the random memory address happens to be inside the memory space your program already owns. God help you if it overwrites a data structure you are using elsewhere in your program.

Not sure exactly what you're needing this for, so this answer may not be relevant. You can always save the output of a command: netstat >> output.txt
, but I don't think that's what you're looking for.
There are of course programming options though; you could simply get a program to read the text file above after that command is run and associate it with a variable, and in Ruby, my language of choice, you can create a variable out of command output using 'backticks':
output = `ls` #(this is a comment) create variable out of command
if output.include? "Downloads" #if statement to see if command includes 'Downloads' folder
print "there appears to be a folder named downloads in this directory."
else
print "there is no directory called downloads in this file."
end
Stick this in a .rb file and run it: ruby file.rb
and it will create a variable out of the command and allow you to manipulate it.

linearLayout.setBackgroundColor(getResources().getColor(R.color.full_white));
setContentView(linearLayout,layoutParams);
None of the others worked for using the same activity and changing the margins based on opening the activity from a different menu! setLayoutParams never worked for me - the device would crash every single time. Even though these are hardcoded numbers - this is only an example of the code for demonstration purposes only.
Unfortunately, not really implemented in ES6. You have this feature with OrderedMap.sort() from ImmutableJS or _.sortBy() from Lodash.
when you perform a test, you ever have the probabilty to reject the null hypothesis when it is true.
See the nextt R code:
p=function(n){
x=rnorm(n,0,1)
s=shapiro.test(x)
s$p.value
}
rep1=replicate(1000,p(5))
rep2=replicate(1000,p(100))
plot(density(rep1))
lines(density(rep2),col="blue")
abline(v=0.05,lty=3)
The graph shows that whether you have a sample size small or big a 5% of the times you have a chance to reject the null hypothesis when it s true (a Type-I error)
Your code compiles just fine. However, your array initialization line is wrong:
int array[]={};
What this does is declare an array with a size equal to the number of elements in the brackets. Since there is nothing in the brackets, you're saying the size of the array is 0 - this renders the array completely useless, since now it can't store anything.
Instead, you can either initialize the array right in your original line:
int array[] = { 5, 5, 5, 5 };
Or you can declare the size and then populate it:
int array[] = new int[4];
// ...while loop
If you don't know the size of the array ahead of time (for example, if you're reading a file and storing the contents), you should use an ArrayList
instead, because that's an array that grows in size dynamically as more elements are added to it (in layman's terms).
Another option is Array.isArray()
if(! Array.isArray(classNames) ){
classNames = [classNames]
}
Initial Check.
1) When you are exporting the DISPLAY to other machine, ensure you entered the command xhost +
on that machine. This command allows to other machine to export their DISPLAY on this machine. There may be security constraints, just know about it. Need to check ssh -X MachineIP
will not require xhost +
?
2) Some times JCONSOLE
won't show all its process, since those JVM process may run with different user and you are exporting the DISPLAY with another user. so better follow CD_DIR>sudo ./jconsole
3) In WAS (WEBSPHERE); jconsole won't be able to connect its java server process, that time just go till the link, then try connecting it. This worked for me. May be this page is initializing some variables to enable jconsole to connect with that server.
WAS console > Application servers > server1 > Process definition > Java Virtual Machine
I have faced the same issue with AIX (where command line interface only available, There is no DISPLAY UI) machine. I resolved by installing
NX Client for Windows
Step 1: Through that Windows machine, I connected with unix box where GUI console is available.
Step 2: SSH to the AIX box from that UNIX box.
Step 3: set DISPLAY like "export DISPLAY=UNIXMACHINE:NXClientPORTConnectedMentionedOnTitle"
Step 4: Now if we launch any programs which requires DISPLAY; it will be launched on this UNIX box.
VNC
If you installed VNC on UNIX box where display is available; then Windows and NX Client is not required.
Step 1: Use VNC to connect with Unix box where GUI console is available.
Step 2: SSH to the AIX box from that UNIX box.
Step 3: set DISPLAY like "export DISPLAY=UNIXMACHINE:VNCPORT"
Step 4: Now if we launch any programs which requires DISPLAY; it will be launched on this UNIX box.
ELSE
Step 1: SSH to the AIX box from that UNIX box.
Step 2: set DISPLAY like "export DISPLAY=UNIXMACHINE:VNCPORT"
Step 3: Now if we launch any programs which requires DISPLAY; it will be launched on this UNIX box.

Simply use ImageButton View and set image for it:`
<ImageButton
android:id="@+id/searchImageButton"

You can't create arrays with a generic component type.
Create an array of an explicit type, like Object[]
, instead. You can then cast this to PCB[]
if you want, but I don't recommend it in most cases.
PCB[] res = (PCB[]) new Object[list.size()]; /* Not type-safe. */
If you want type safety, use a collection like java.util.List<PCB>
instead of an array.
By the way, if list
is already a java.util.List
, you should use one of its toArray()
methods, instead of duplicating them in your code. This doesn't get your around the type-safety problem though.
Visual Studio is by itself covering the console window, try minimizing Visual Studio window they are drawn over each other.
That's unnecessary. Just use SELECT CONVERT(column USING utf8) FROM
..... instead of just SELECT column FROM
...
INADDR_ANY
is used when you don't need to bind a socket to a specific IP. When you use this value as the address when calling bind()
, the socket accepts connections to all the IPs of the machine.
For what it's worth, I found the following syntax to work the best:
SELECT * FROM [LINKED_SERVER]...[TABLE]
I couldn't get the recommendations of others to work, using the database name. Additionally, this data source has no schema.
Define a class
import logging

This solution works on Mac OS, IDE terminals. Looks like the Windows command prompt doesn't have colors at all by default. Here are instructions on how to enable them, which I haven't try https://www.howtogeek.com/322432/how-to-customize-your-command-prompts-color-scheme-with-microsofts-colortool/
Maybe you'll also want decimal separator? Here is a function I just made:
function formatFloat(num,casasDec,sepDecimal,sepMilhar) {
if (num < 0)
{
num = -num;
sinal = -1;
} else
sinal = 1;
var resposta = "";
var part = "";
if (num != Math.floor(num)) // decimal values present
{
part = Math.round((num-Math.floor(num))*Math.pow(10,casasDec)).toString(); // transforms decimal part into integer (rounded)
while (part.length < casasDec)
part = '0'+part;
if (casasDec > 0)
{
resposta = sepDecimal+part;
num = Math.floor(num);
} else
num = Math.round(num);
} // end of decimal part
while (num > 0) // integer part
{
part = (num - Math.floor(num/1000)*1000).toString(); // part = three less significant digits
num = Math.floor(num/1000);
if (num > 0)
while (part.length < 3) // 123.023.123 if sepMilhar = '.'
part = '0'+part; // 023
resposta = part+resposta;
if (num > 0)
resposta = sepMilhar+resposta;
}
if (sinal < 0)
resposta = '-'+resposta;
return resposta;
}
In case this can help anyone, here's simple CSS as a jumping off point. Turns it into a basic rounded square big enough for thumbs with a toggled background color.

Use snprintf
, it is more portable than itoa
.
itoa is not part of standard C, nor is it part of standard C++; but, a lot of compilers and associated libraries support it.
Example of sprintf
char* buffer = ... allocate a buffer ...
int value = 4564;
sprintf(buffer, "%d", value);
Example of snprintf
char buffer[10];
int value = 234452;
snprintf(buffer, 10, "%d", value);
Both functions are similar to fprintf
, but output is written into an array rather than to a stream. The difference between sprintf
and snprintf
is that snprintf
guarantees no buffer overrun by writing up to a maximum number of characters that can be stored in the buffer
.
FileNameOnly = Dir(.SelectedItems(1))
Your mistake is looking for range
, which gives you the range
of a vector, for example:
range(c(10, -5, 100))
gives
-5 100
Instead, look at the :
operator to give sequences (with a step size of one):
1:100
or you can use the seq
function to have a bit more control. For example,
##Step size of 2
seq(1, 100, by=2)
or
##length.out: desired length of the sequence
seq(1, 100, length.out=5)
you can try to replace -->
with a different string say, #END#
and do search and replace with your editor when you wish to return the closing tags.
For the times when some fields have a ";" and some do not you can also add a semi-colon to the field and use the same method described.
SET MyText = LEFT(MyText+';', CHARINDEX(';',MyText+';')-1)
1) Try putting an absolute link not relative link to your eot font - somehow old IE just don't know in which folder the css file is 2) make 2 extra @font-face declarations so it should look like this:
@font-face { /* for modern browsers and modern IE */
font-family: "Futura";
src: url("../fonts/Futura_Medium_BT.eot");
src: url("../fonts/Futura_Medium_BT.eot?#iefix") format("embedded-opentype"),
url( "../fonts/Futura_Medium_BT.ttf" ) format("truetype");
}
@font-face{ /* for old IE */
font-family: "Futura_IE";
src: url(/wp-content/themes/my-theme/fonts/Futura_Medium_BT.eot);
}
@font-face{ /* for old IE */
font-family: "Futura_IE2";
src:url(/wp-content/themes/my-theme/fonts/Futura_Medium_BT.eot?#iefix)
format("embedded-opentype");
}
.p{ font-family: "Futura", "Futura_IE", "Futura_IE2", Arial, sans-serif;
This is an example for wordpress template - absolute link should point from where your start index file is.
It seems, fileinput.FileInput is a generator. As such, you can only iterate over it once, then all items have been consumed and calling it's next method raises StopIteration. If you want to iterate over the lines more than once, you can put them in a list:
list(fileinput.FileInput('test.txt'))
Then call rstrip on them.
I found this one from another post (can't remember which) and while not the most elegant, it's simple and as a novice Linux user has given me no trouble
for i in *old_str* ; do mv -v "$i" "${i/\old_str/new_str}" ; done
if you have spaces or other special characters use a \
for i in *old_str\ * ; do mv -v "$i" "${i/\old_str\ /new_str}" ; done
for strings in sub-directories use **
for i in *\*old_str\ * ; do mv -v "$i" "${i/\old_str\ /new_str}" ; done
In python cv2
not updated the division calculation. so, you must include from __future__ import division
in first line of the program.
I would recommend using the visual designer built into VS2008, as updating the dbml also updates the code that is generated for you. Modifying the dbml outside of the visual designer would result in the underlying code being out of sync.
OPTION 1: if you want to make a common utility function then you can use this
export function getCurrentDate(separator=''){
let newDate = new Date()
let date = newDate.getDate();
let month = newDate.getMonth() + 1;
let year = newDate.getFullYear();
return `${year}${separator}${month<10?`0${month}`:`${month}`}${separator}${date}`
}
and use it by just importing it as
import {getCurrentDate} from './utils'
console.log(getCurrentDate())
OPTION 2: or define and use in a class directly
getCurrentDate(separator=''){
let newDate = new Date()
let date = newDate.getDate();
let month = newDate.getMonth() + 1;
let year = newDate.getFullYear();
return `${year}${separator}${month<10?`0${month}`:`${month}`}${separator}${date}`
}
Modern linux systems will normally only have entries in /dev for devices that exist, so going through hda* and sda* as you suggest would work fairly well.
Otherwise, there may be something in /proc you can use. From a quick look in there, I'd have said /proc/partitions looks like it could do what you need.

Bootstrap leverages HTML5 standards in order to access DOM element attributes easily within javascript.
Forms a class of attributes, called custom data attributes, that allow proprietary information to be exchanged between the HTML and its DOM representation that may be used by scripts. All such custom data are available via the HTMLElement interface of the element the attribute is set on. The HTMLElement.dataset property gives access to them.
You use css to change the opacity. To cope with IE you'd need something like:
.opaque {
opacity : 0.3;
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=30)";
filter: alpha(opacity=30);
}
But the only problem with this is that it means anything inside the container will also be 0.3 opacity. Thus you'll have to change your HTML to have another container, not inside the transparent one, that holds your content.
Otherwise the png technique, would work. Except you'd need a fix for IE6, which in itself could cause problems.
Linux is a kernel, not a full operating system. There are different windowing systems and gui's that run on top of Linux to provide windowing. Typically X11 is the windowing system used by Linux distros.
As Sagi stated in their answer DataTable.Load is a good solution. If you are trying to load multiple tables from a single reader you do not need to call DataReader.NextResult. The DataTable.Load method also advances the reader to the next result set (if any).
// Read every result set in the data reader.
while (!reader.IsClosed)
{
DataTable dt = new DataTable();
// DataTable.Load automatically advances the reader to the next result set
dt.Load(reader);
items.Add(dt);
}
Get and set with default values.

Using Hex
in Apache Commons:
String hexString = "fd00000aa8660b5b010006acdc0100000101000100010000";
byte[] bytes = Hex.decodeHex(hexString.toCharArray());
System.out.println(new String(bytes, "UTF-8"));
"Whitespace" includes space, tabs, and CRLF. So an elegant and one-liner string function we can use is str.translate
:
Python 3
' hello apple '.translate(str.maketrans('', '', ' \n\t\r'))
OR if you want to be thorough:
import string
' hello apple'.translate(str.maketrans('', '', string.whitespace))
Python 2
' hello apple'.translate(None, ' \n\t\r')
OR if you want to be thorough:
import string
' hello apple'.translate(None, string.whitespace)
In the example above. For me, this if($response.success==false)
thing does not work. Here is correct PHP code:
$url = 'https://www.google.com/recaptcha/api/siteverify';
$privatekey = "--your_key--";
$response = file_get_contents($url."?secret=".$privatekey."&response=".$_POST['g-recaptcha-response']."&remoteip=".$_SERVER['REMOTE_ADDR']);
$data = json_decode($response);
if (isset($data->success) AND $data->success==true) {
// everything is ok!
} else {
// spam
}
You can use date filter to convert in date and display in specific format.
In .ts file (typescript):
let dateString = '1968-11-16T00:00:00'
let newDate = new Date(dateString);
In HTML:
{{dateString | date:'MM/dd/yyyy'}}
Below are some formats which you can implement :
Backend:
public todayDate = new Date();
HTML :
<select>
<option value=""></option>
<option value="MM/dd/yyyy">[{{todayDate | date:'MM/dd/yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy">[{{todayDate | date:'EEEE, MMMM d, yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm a'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm:ss a'}}]</option>
<option value="MM/dd/yyyy h:mm a">[{{todayDate | date:'MM/dd/yyyy h:mm a'}}]</option>
<option value="MM/dd/yyyy h:mm:ss a">[{{todayDate | date:'MM/dd/yyyy h:mm:ss a'}}]</option>
<option value="MMMM d">[{{todayDate | date:'MMMM d'}}]</option>
<option value="yyyy-MM-ddTHH:mm:ss">[{{todayDate | date:'yyyy-MM-ddTHH:mm:ss'}}]</option>
<option value="h:mm a">[{{todayDate | date:'h:mm a'}}]</option>
<option value="h:mm:ss a">[{{todayDate | date:'h:mm:ss a'}}]</option>
<option value="EEEE, MMMM d, yyyy hh:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy hh:mm:ss a'}}]</option>
<option value="MMMM yyyy">[{{todayDate | date:'MMMM yyyy'}}]</option>
</select>
If you put blah="/usr/bin/blah"
in your ~/.bashrc
then you can use $blah
in your login shell as a substitute for typing /usr/bin/blah

687
>>> print int('11111111',2)

Another way.
You may not have permission to dba_sequences. So you can always just do:
select * from user_sequences;
This KineticModel

Why is this happening?
The entire ext/mysql
PHP extension, which provides all functions named with the prefix mysql_
, was officially deprecated in PHP v5.5.0 and removed in PHP v7.
It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.
The manual has contained warnings against its use in new code since June 2011.
How can I fix it?
As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql
. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.
They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.
Hashphp.org has an excellent tutorial on migrating from ext/mysql
to PDO.
I understand that it's possible to suppress deprecation errors by setting
error_reporting
inphp.ini
to excludeE_DEPRECATED
:error_reporting = E_ALL ^ E_DEPRECATED
What will happen if I do that?
Yes, it is possible to suppress such error messages and continue using the old ext/mysql
extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.
Note also that this technique will suppress all E_DEPRECATED
messages, not just those to do with the ext/mysql
extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @
—however this will suppress all errors raised by that expression, not just E_DEPRECATED
ones.
You are starting a new project.
There is absolutely no reason to use ext/mysql
—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.
You have (your own) legacy codebase that currently depends upon ext/mysql
.
It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.
Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.
Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.
The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.
Consider whether you really need to upgrade to PHP v5.5 at this time.
You should begin planning to replace ext/mysql
with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.
However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.
You are using a third party project that depends upon ext/mysql
.
Consider whether you really need to upgrade to PHP v5.5 at this time.
Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.
It is absolutely essential to perform regression testing.
There is a limit, yes. See ulimit
.
Also you need to consider the TIMED_WAIT
state. Once a TCP socket is closed (by default) the port remains occupied in TIMED_WAIT
status for 2 minutes. This value is tunable. This will also "run you out of sockets" even though they are closed.
Run netstat
to see the TIMED_WAIT
stuff in action.
P.S. The reason for TIMED_WAIT
is to handle the case of packets arriving after the socket is closed. This can happen because packets are delayed or the other side just doesn't know that the socket has been closed yet. This allows the OS to silently drop those packets without a chance of "infecting" a different, unrelated socket connection.
mayby one little change from the top answer, because DB_NAME()
returns always content db of execution. so, for me better like below:
sp_MSforeachdb 'select DB_name(db_id(''?'')) as DB, * From ?..sysobjects where xtype in (''U'', ''P'') And name like ''[_]x[_]%'''
In my case I was looking for tables their names started with _x_
Cheers, Ondrej
If you have proportioned elements, you could use:
.valid {
background-position: 98% center;
}
.half .valid {
background-position: 96% center;
}
In this example, .valid
would be the class with the picture and .half
would be a row with half the size of the standard one.
Dirty, but works as a charm and it's reasonably manageable.
I've used this in beamer
, but not for general documents, but it looks like that's what the original hint suggests
\newenvironment{changemargin}[2]{%

\setlength{\rightmargin}{#2}%
\setlength{\listparindent}{\parindent}%

\setlength{\parsep}{\parskip}%
}%
\item[]}{\end{list}}
Then to use it
\begin{changemargin}{-1cm}{-1cm}
don't forget to

I got this from Changing margins “on the fly” in the TeX FAQ.
I ran into similar problem - Invalid value encountered in ... After spending a lot of time trying to figure out what is causing this error I believe in my case it was due to NaN in my dataframe. Check out working with missing data in pandas.
None == None True
np.nan == np.nan False
When NaN is not equal to NaN then arithmetic operations like division and multiplication causes it throw this error.
Couple of things you can do to avoid this problem:
Use pd.set_option to set number of decimal to consider in your analysis so an infinitesmall number does not trigger similar problem - ('display.float_format', lambda x: '%.3f' % x).
Use df.round() to round the numbers so Panda drops the remaining digits from analysis. And most importantly,
Set NaN to zero df=df.fillna(0). Be careful if Filling NaN with zero does not apply to your data sets because this will treat the record as zero so N in the mean, std etc also changes.

According to the docs of setState()
the new state might not get reflected in the callback function findRoutes()
. Here is the extract from React docs:
setState() does not immediately mutate this.state but creates a pending state transition. Accessing this.state after calling this method can potentially return the existing value.
There is no guarantee of synchronous operation of calls to setState and calls may be batched for performance gains.
So here is what I propose you should do. You should pass the new states input
in the callback function findRoutes()
.
handleFormSubmit: function(input){
// Form Input
this.setState({
originId: input.originId,
destinationId: input.destinationId,
radius: input.radius,
search: input.search
});
this.findRoutes(input); // Pass the input here
}
The findRoutes()
function should be defined like this:
findRoutes: function(me = this.state) { // This will accept the input if passed otherwise use this.state
if (!me.originId || !me.destinationId) {
alert("findRoutes!");
return;
}
var p1 = new Promise(function(resolve, reject) {
directionsService.route({
origin: {'placeId': me.originId},
destination: {'placeId': me.destinationId},
travelMode: me.travelMode
}, function(response, status){
if (status === google.maps.DirectionsStatus.OK) {
// me.response = response;
directionsDisplay.setDirections(response);
resolve(response);
} else {

Sometimes it happens when you change the remote bitbucket account password.
Solution
Go to Control panel => User Accounts => Credential Manager => Windows Credentials => move to Generic credentials and change the password of account
After some search, I've found a cleaner solution wich use the %
operator.
In your YAML file :
key : 'This is the foobar var : %{foobar}'
In your ruby code :
require 'yaml'
file = YAML.load_file('your_file.yml')
foobar = 'Hello World !'
content = file['key']
modified_content = content % { :foobar => foobar }
puts modified_content
And the output is :
This is the foobar var : Hello World !
As @jschorr said in the comment, you can also add multiple variable to the value in the Yaml file :
Yaml :
key : 'The foo var is %{foo} and the bar var is %{bar} !'
Ruby :
# ...
foo = 'FOO'
bar = 'BAR'
# ...
modified_content = content % { :foo => foo, :bar => bar }
Output :
The foo var is FOO and the bar var is BAR !
Dirk Eddelbuettel's answer is the best; here I just note that you can get away with not pre-specifying the dataframe dimensions or data types, which is sometimes useful if you have multiple data types and lots of columns:
row1<-list("a",1,FALSE) #use 'list', not 'c' or 'cbind'!
row2<-list("b",2,TRUE)
df<-data.frame(row1,stringsAsFactors = F) #first row
df<-rbind(df,row2) #now this works as you'd expect.
db.messages.find( { headers : { From: "[email protected]" } } )
This queries for documents where headers
equals { From: ... }
, i.e. contains no other fields.
db.messages.find( { 'headers.From': "[email protected]" } )
This only looks at the headers.From
field, not affected by other fields contained in, or missing from, headers
.
If you want to keep your working changes while performing a rebase, you can use --autostash
. From the documentation:
Before starting rebase, stash local modifications away (see git-stash[1]) if needed, and apply the stash when done.
For example:
git pull --rebase --autostash
Why use a <a href>
? I solve it like this:
<span class='a'>fake link</span>
And style it with:
.a {text-decoration:underline; cursor:pointer;}
You can easily access it with jQuery:
$(".a").click();
sudo netstat -lpn |grep :'3000'
3000 is port i was looking for, After first command you will have Process ID for that port
kill -9 1192
in my case 1192 was process Id of process running on 3000 PORT use -9 for Force kill the process
For Django3.0+, use models.TextChoices
(see docs-v3.0 for enumeration types)
from django.db import models
class MyModel(models.Model):
class Month(models.TextChoices):
JAN = '1', "JANUARY"
FEB = '2', "FEBRUARY"
MAR = '3', "MAR"
# (...)
month = models.CharField(
max_length=2,
choices=Month.choices,
default=Month.JAN
)
Usage::
>>> obj = MyModel.objects.create(month='1')
>>> assert obj.month == obj.Month.JAN
>>> assert MyModel.Month(obj.month).label == 'JANUARY'
>>> assert MyModel.objects.filter(month=MyModel.Month.JAN).count() >= 1
>>> obj2 = MyModel(month=MyModel.Month.FEB)
>>> assert obj2.get_month_display() == obj2.Month(obj2.month).label
I was getting confused with wordpress shortcode attributes, I decided to write a custom function to handle all possibilities. maybe it's useful for someone:
function stringToBool($str){
if($str === 'true' || $str === 'TRUE' || $str === 'True' || $str === 'on' || $str === 'On' || $str === 'ON'){
$str = true;
}else{
$str = false;
}
return $str;
}
stringToBool($atts['onOrNot']);
1) You can set it with TypeFace. 2) You can directly use in strings.xml(in your values folder) 3) You can String myNewString = " This is my bold text This is my italics string This is my underlined string
Try following, which will convert convert single and double digit numbers to 3 digit numbers by prefixing zeros.
var base_number = 2;
var zero_prefixed_string = ("000" + base_number).slice(-3);
Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.
First the actual accounts:
LocalService account (preferred)
A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.
NT AUTHORITY\LocalService
HKEY_USERS\S-1-5-19
)
Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).
NT AUTHORITY\NetworkService
MANGO$
) to remote serversHKEY_USERS\S-1-5-20
)NETWORK SERVICE
into the Select User or Group dialog
LocalSystem account (dangerous, don't use!)
Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)
.\LocalSystem
(can also use LocalSystem
or ComputerName\LocalSystem
)HKCU
represents the default user)MANGO$
) to remote servers
Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService
can still access the internet.
The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).
It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.
In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).
In Windows Server 2003 you cannot run a scheduled task as
NT_AUTHORITY\LocalService
(aka the Local Service account), or NT AUTHORITY\NetworkService
(aka the Network Service account). That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.
A service running as NetworkService
presents the machine credentials on the network. This means that if your computer was called mango
, it would present as the machine account MANGO$
:
SELECT * FROM table WHERE timestamp >= '2012-05-05 00:00:00'
AND timestamp <= '2012-05-05 23:59:59'
You're trying to access a JSON, not JSONP.
Notice the difference between your source:
And actual JSONP (a wrapping function):
Search for JSON + CORS/Cross-domain policy and you will find hundreds of SO threads on this very topic.
Two things you need to do, if you want to make a custom button design.
1st is: create a xml resource file in drawable folder (Example: btn_shape_rectangle.xml) then copy and paste the code there.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="16dp"
android:shape="rectangle">
<solid
android:color="#fff"/>
<stroke
android:width="1dp"
android:color="#000000"
/>
<corners android:radius="10dp" />
</shape>
2nd is go to your layout button where you want to implement this design. just link up it. Example: android:background="@drawable/btn_shape_rectangle"
You can change shape color radius what design you want can do.
Hope it will works and help you. Happy Coding
This isn't my answer, but it definitely resonates with me. It's from ThoughtWorks' Technology Radar from October 2012:
Two things have caused fatigue with XML-based build tools like Ant and Maven: too many angry pointy braces and the coarseness of plug-in architectures. While syntax issues can be dealt with through generation, plug-in architectures severely limit the ability for build tools to grow gracefully as projects become more complex. We have come to feel that plug-ins are the wrong level of abstraction, and prefer language-based tools like Gradle and Rake instead, because they offer finer-grained abstractions and more flexibility long term.
First of all print
isn't a function in Python 2, it is a statement.
To suppress the automatic newline add a trailing ,
(comma). Now a space will be used instead of a newline.
Demo:
print 1,
print 2
output:
1 2
Or use Python 3's print()
function:
from __future__ import print_function
print(1, end=' ') # default value of `end` is '\n'
print(2)
As you can clearly see print()
function is much more powerful as we can specify any string to be used as end
rather a fixed space.
public int getActionBarHeight() {
int actionBarHeight = 0;
TypedValue tv = new TypedValue();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv,
true))
actionBarHeight = TypedValue.complexToDimensionPixelSize(
tv.data, getResources().getDisplayMetrics());
} else {
actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,
getResources().getDisplayMetrics());
}
return actionBarHeight;
}
If you are going to create a custom view, make sure it is extending SurfaceView then, you can redraw it with method getHolder().lockCanvas()
. Here is an example:
Canvas c = getHolder().lockCanvas();
c.drawText("Text", x, y, paint);
getHolder().unlockCanvasAndPost(c);
If you init method of timer
let timer = Timer(timeInterval: 3, target: self, selector: #selector(update(_:)), userInfo: [key : value], repeats: false)
func update(_ timer : Timer) {
}
then add it to loop using method other selector will not be called
RunLoop.main.add(timer!, forMode: .defaultRunLoopMode)
NOTE : If you are want this to repeat make repeats true and keep the reference of timer otherwise update method will not be called.
If you are using this method.
Timer.scheduledTimer(timeInterval: seconds, target: self, selector: #selector(update(_:)), userInfo: nil, repeats: true)
keep a reference for later use if repeats is true.
It's called a "finalizer", and you should usually only create one for a class whose state (i.e.: fields) include unmanaged resources (i.e.: pointers to handles retrieved via p/invoke calls). However, in .NET 2.0 and later, there's actually a better way to deal with clean-up of unmanaged resources: SafeHandle. Given this, you should pretty much never need to write a finalizer again.
You can do this:
var getValue = function (input, defaultValue) {
return input.value || defaultValue;
};
If you've done something like accidentally npm link
generator-webapp after you've changed it, you can fix it by cloning the right generator and linking that.
git clone https://github.com/yeoman/generator-webapp.git;
# for fixing generator-webapp, replace with your required repository
cd generator-webapp;
npm link;
This is how I limit the results in MS SQL Server 2012:
SELECT *
FROM table1
ORDER BY columnName
OFFSET 10 ROWS FETCH NEXT 10 ROWS ONLY
NOTE: OFFSET
can only be used with or in tandem to ORDER BY
.
To explain the code line OFFSET xx ROWS FETCH NEXT yy ROW ONLY
The xx
is the record/row number you want to start pulling from in the table, i.e: If there are 40 records in table 1, the code above will start pulling from row 10.
The yy
is the number of records/rows you want to pull from the table.
To build on the previous example: If table 1 has 40 records and you began pulling from row 10 and grab the NEXT set of 10 (yy
).
That would mean, the code above will pull the records from table 1 starting at row 10 and ending at 20. Thus pulling rows 10 - 20.
Check out the link for more info on OFFSET
That system is 32bit. iX86 in uname
means it is a 32-bit architecture. If it was 64 bit, it would return

If you get an error indicating that you must call makeText, the following code will fix it:
Toast toast= Toast.makeText(getApplicationContext(),
"Your string here", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.TOP|Gravity.CENTER_HORIZONTAL, 0, 0);
toast.show();
You could do this
$("#input").blur(function(){
if($(this).val() == ''){
alert('empty');
}
});
http://jsfiddle.net/jasongennaro/Y5P9k/1/
When the input has lost focus
that is .blur()
, then check the value of the #input
.
If it is empty == ''
then trigger the alert.
<html>
<body>
<input id="mycheck" type="checkbox">
</body>
<script language="javascript">

I had the same problem. Here's what I figured out:
=BDP(A1&"@BGN Corp", "Issuer_parent_eqy_ticker")
A1 being the ISINs. This will return the ticker number. Then just use the ticker number to get the price.
is this what you want?
var grouped = CustomerList.GroupBy(m => m.GroupID).Select((n) => new { GroupId = n.Key, Items = n.ToList() });

well, for me it was different. I was missing assembly of my console application project with MVC project. So, adding reference was not enough.
well this might help someone else. go to root web.config file system.web
-> compilation
-> add your project reference like this.
<assemblies>
<add assembly="Your.Namespace, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
</assemblies>
What you want is this constructor:
std::string ( const string& str, size_t pos, size_t n = npos )
, passing pos as 0. Your const char* c-style string will get implicitly cast to const string for the first parameter.
const char *c_style = "012abd";
std::string cpp_style = new std::string(c_style, 0, 10);
I'd use iloc
, which takes a row/column slice, both based on integer position and following normal python syntax. If you want every 5th row:
df.iloc[::5, :]

var refreshControl: UIRefreshControl!
override func viewDidLoad() {
super.viewDidLoad()
refreshControl = UIRefreshControl()
refreshControl.attributedTitle = NSAttributedString(string: "Pull to refresh")
refreshControl.addTarget(self, action: #selector(refresh), for: .valueChanged)
tableView.addSubview(refreshControl)
}
@objc func refresh(_ sender: Any) {
// your code to reload tableView
}
And you could stop refreshing with:
refreshControl.endRefreshing()
It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.
Edit: This is what the forums say:
By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.
To disable:
/system/bin/bugmailer.sh must be deleted/renamed.

For apache POI 3.9 you can use the code bellow:
HSSFCellStyle style = workbook.createCellStyle()
style.setFillForegroundColor(HSSFColor.YELLOW.index)

Assuming your sample data is correct, your givenname, and other entries wrapped in brackets are arrays in JS... you'll want to use List for those data types. and List for say accountstatusexpmaxdate... I think you example has the dates incorrectly formatted though, so uncertain as to what else is incorrect in your example.
This is an old post, but wanted to make note of the issues.
I start with the following template, which is derived from numerous printings of Itzik Ben-Gan's routine:
;WITH
Pass0 as (select 1 as C union all select 1), --2 rows
Pass1 as (select 1 as C from Pass0 as A, Pass0 as B),--4 rows
Pass2 as (select 1 as C from Pass1 as A, Pass1 as B),--16 rows
Pass3 as (select 1 as C from Pass2 as A, Pass2 as B),--256 rows
Pass4 as (select 1 as C from Pass3 as A, Pass3 as B),--65536 rows
Pass5 as (select 1 as C from Pass4 as A, Pass4 as B),--4,294,967,296 rows
Tally as (select row_number() over(order by C) as Number from Pass5)
select Number from Tally where Number <= 1000000
The "WHERE N<= 1000000" clause limits the output to 1 to 1 million, and can easily be adjusted to your desired range.
Since this is a WITH clause, it can be worked into an INSERT... SELECT... like so:
-- Sample use: create one million rows
CREATE TABLE dbo.Example (ExampleId int not null)
DECLARE @RowsToCreate int
SET @RowsToCreate = 1000000
-- "Table of numbers" data generator, as per Itzik Ben-Gan (from multiple sources)
;WITH
Pass0 as (select 1 as C union all select 1), --2 rows
Pass1 as (select 1 as C from Pass0 as A, Pass0 as B),--4 rows
Pass2 as (select 1 as C from Pass1 as A, Pass1 as B),--16 rows
Pass3 as (select 1 as C from Pass2 as A, Pass2 as B),--256 rows
Pass4 as (select 1 as C from Pass3 as A, Pass3 as B),--65536 rows
Pass5 as (select 1 as C from Pass4 as A, Pass4 as B),--4,294,967,296 rows
Tally as (select row_number() over(order by C) as Number from Pass5)
INSERT Example (ExampleId)
select Number
from Tally
where Number <= @RowsToCreate
Indexing the table after it's built will be the fastest way to index it.
Oh, and I'd refer to it as a "Tally" table. I think this is a common term, and you can find loads of tricks and examples by Googling it.
Instead of override you can add another class to the element and then you have an extra abilities. for example:
HTML
<div class="style1 style2"></div>
CSS
//only style for the first stylesheet
.style1 {
width: 100%;
}
//only style for second stylesheet
.style2 {
width: 50%;
}
//override all
.style1.style2 {
width: 70%;
}
to check for undefined and null in javascript you need just to write the following :
if (!var) {
console.log("var IS null or undefined");
} else {
console.log("var is NOT null or undefined");
}
Basically there are two ways: query DB (data length + index length) or check files size. Index length is related to data stored in indexes.
Everything is described here:
http://www.mkyong.com/mysql/how-to-calculate-the-mysql-database-size/

Case "userID"
' does something here.
Case "packageID"

Exit Select
End Select
Is there a reason for the goto? If it doesn't meet the if criterion, it will simply not perform the function and go to the next case.

RichTextBox will allow you to use html to specify the color. Another alternative is using a listbox and using the DrawItem event to draw how you would like. AFAIK, textbox itself can't be used in the way you're hoping.
It can be used for a simple table, for example in an insert-only audit table, where there is no update to existing row, and no fk to other table. The insert is a simple insert, which has no or little chance of rollback.
The key advantage is isolation. A crashing process won't bring down other processes, whereas a crashing thread will probably wreak havoc with other threads.
Here's some information from Scott Gu's Blog posted by Jeff on what's actually taking place:
For those who are seeing this exception:
"The model backing the 'Production' context has changed since the database was created. Either manually delete/update the database, or call
Database.SetInitializer
with anIDatabaseInitializer
instance."Here is what is going on and what to do about it:
When a model is first created, we run a DatabaseInitializer to do things like create the database if it's not there or add seed data. The default DatabaseInitializer tries to compare the database schema needed to use the model with a hash of the schema stored in an EdmMetadata table that is created with a database (when Code First is the one creating the database). Existing databases won’t have the EdmMetadata table and so won’t have the hash…and the implementation today will throw if that table is missing. We'll work on changing this behavior before we ship the fial version since it is the default. Until then, existing databases do not generally need any database initializer so it can be turned off for your context type by calling:
Database.SetInitializer<YourDbContext>(null);

If you are referring to the System.Net.HttpClient in .NET 4.5, you can get the content returned by GetAsync using the HttpResponseMessage.Content property as an HttpContent-derived object. You can then read the contents to a string using the HttpContent.ReadAsStringAsync method or as a stream using the ReadAsStreamAsync method.
The HttpClient class documentation includes this example:
HttpClient client = new HttpClient();
HttpResponseMessage response = await client.GetAsync("http://www.contoso.com/");
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
To round out the possibilities, you can use writeLines()
with sink()
, if you want:
> sink("tempsink", type="output")
> writeLines("Hello\nWorld")
> sink()
> file.show("tempsink", delete.file=TRUE)
Hello
World
To me, it always seems most intuitive to use print()
, but if you do that the output won't be what you want:
...
> print("Hello\nWorld")
...
[1] "Hello\nWorld"

document.write("<b>" + day + "/" + month + "/" + year + "</b>")

The answers above are good, but insufficient if you have more than 1 project (.csproj) in the same folder.
First, you easily add the "PackageReference" tag to the .csproj file (either manually, by using the nuget package manager or by using the dotnet add package command).
But then, you need to run the "restore" command manually so you can tell it which project you are trying to restore (if I just clicked the restore button that popped up, nothing happened). You can do that by running:
dotnet restore Project-File-Name.csproj
And that installs the package
df.iloc[df['columnX'].argmax()]
argmax()
would provide the index corresponding to the max value for the columnX. iloc
can be used to get the row of the DataFrame df for this index.
