I can't get that constructor to work either. This however seems to work:
# $temp = Get-ResourceFiles
$resourceFiles = New-Object System.Collections.ArrayList($null)
$resourceFiles.AddRange($temp)
You can also pass an integer in the constructor to set an initial capacity.
What do you mean when you say you want to enumerate the files? Why can't you just filter the wanted values into a fresh array?
Edit:
It seems that you can use the array constructor like this:
$resourceFiles = New-Object System.Collections.ArrayList(,$someArray)
Note the comma. I believe what is happening is that when you call a .NET method, you always pass parameters as an array. PowerShell unpacks that array and passes it to the method as separate parameters. In this case, we don't want PowerShell to unpack the array; we want to pass the array as a single unit. Now, the comma operator creates arrays. So PowerShell unpacks the array, then we create the array again with the comma operator. I think that is what is going on.
Had same issue, this is how I resolved... Simple and elegant. The "4" is how long the string should be, no matter what length of integer is passed it will pad with zero's up to "4".

Letting a parent have pointer-events: none
will disable the child a-tag
like this (requires that the div covers the a and hasn't 0 width/height):
<div class="disabled">

where:
.disabled {
pointer-events: none;

Try to get a newer g++

You may consider using configure_file with the COPYONLY
option:
configure_file(<input> <output> COPYONLY)
Unlike file(COPY ...)
it creates a file-level dependency between input and output, that is:
If the input file is modified the build system will re-run CMake to re-configure the file and generate the build system again.
When you have repeated notifications at future, you do not want to cancel those notifications, you can clear the item in notification center by:
func clearNotificationCenter() {
UIApplication.sharedApplication().applicationIconBadgeNumber = 1
UIApplication.sharedApplication().applicationIconBadgeNumber = 0
}
You cannot clear notification when your app is open in the foreground by calling the method below immediately after receiving local notification, otherwise you will receive tens of hundreds of notifications. Maybe because the same notification apply again, and now is the time to fire, so you keep fire, apply again, fire, apply....:
[UIApplication sharedApplication].scheduledLocalNotifications = [UIApplication sharedApplication].scheduledLocalNotifications;
Blogged about it on my blog :) Short version is, to find the full names of the resources(unless you already know them):
var assembly = Assembly.GetExecutingAssembly();
foreach (var resourceName in assembly.GetManifestResourceNames())
System.Console.WriteLine(resourceName);
To use all of them for something:
foreach (var resourceName in assembly.GetManifestResourceNames())
{
using(var stream = assembly.GetManifestResourceStream(resourceName))
{
// Do something with stream
}
}
To use resources in other assemblies than the executing one, you'd just get a different assembly object by using some of the other static methods of the Assembly
class. Hope it helps :)
I prefer this solution on java 8:
Files.walk(pathToBeDeleted)
.sorted(Comparator.reverseOrder())
.map(Path::toFile)
.forEach(File::delete);

It comes with lots of easy array functions to never write a loop again
So you can just do:
NSArray* youngHeroes = [self.heroes filter:^BOOL(Hero *object) {
return object.age.intValue < 20;
}];
or
NSArray* oldHeroes = [self.heroes reject:^BOOL(Hero *object) {
return object.age.intValue < 20;
}];
In JavaScript you cannot have the direct access to the filesystem.
However, you can make browser to pop up a dialog window allowing the user to pick the save location. In order to do this, use the replace
method with your Base64String and replace "image/png"
with "image/octet-stream"
:
"data:image/png;base64,iVBORw0KG...".replace("image/png", "image/octet-stream");
Also, W3C-compliant browsers provide 2 methods to work with base64-encoded and binary data:
Probably, you will find them useful in a way...
Here is a refactored version of what I understand you need:
window.addEventListener('DOMContentLoaded', () => {_x000D_
const img = document.getElementById('embedImage');_x000D_
img.src = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA' +_x000D_
'AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO' +_x000D_

const button = document.getElementById('saveImage');_x000D_
button.addEventListener('click', () => {_x000D_
window.location.href = img.src.replace('image/png', 'image/octet-stream');_x000D_

The is
keyword is a test for object identity while ==
is a value comparison.
If you use is
, the result will be true if and only if the object is the same object. However, ==
will be true any time the values of the object are the same.
If you are using BaseFragment for your app then you can add onBackPressedDispatcher to your base fragment.
//Make a BaseFragment for all your fragments
abstract class BaseFragment : Fragment() {
private lateinit var callback: OnBackPressedCallback
/**
* SetBackButtonDispatcher in OnCreate
*/
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setBackButtonDispatcher()
}
/**
* Adding BackButtonDispatcher callback to activity
*/
private fun setBackButtonDispatcher() {
callback = object : OnBackPressedCallback(true) {
override fun handleOnBackPressed() {
onBackPressed()
}
}
requireActivity().onBackPressedDispatcher.addCallback(this, callback)
}
/**
* Override this method into your fragment to handleBackButton
*/
open fun onBackPressed() {
}
}
Override onBackPressed() in your fragment by extending basefragment
//How to use this into your fragment
class MyFragment() : BaseFragment(){
private lateinit var mView: View
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
mView = inflater.inflate(R.layout.fragment_my, container, false)
return mView.rootView
}
override fun onBackPressed() {
//Write your code here on back pressed.
}
}
For those who are still having hard time understanding this strtok()
function, take a look at this pythontutor example, it is a great tool to visualize your C (or C++, Python ...) code.
In case the link got broken, paste in:
#include <stdio.h>
#include <string.h>
int main()
{
char s[] = "Hello, my name is? Matthew! Hey.";
char* p;
for (char *p = strtok(s," ,?!."); p != NULL; p = strtok(NULL, " ,?!.")) {
puts(p);
}
return 0;
}

Using jQuery and knockout:
With this binding main checkbox stays in sync with underliying checkboxes, it will be unchecked unless all checkboxes checked.
ko.bindingHandlers.allChecked = {
init: function (element, valueAccessor) {
var selector = valueAccessor();
function getChecked () {
element.checked = $(selector).toArray().every(function (checkbox) {
return checkbox.checked;
});
}
function setChecked (value) {
$(selector).toArray().forEach(function (checkbox) {
if (checkbox.checked !== value) {
checkbox.click();
}
});
}
ko.utils.registerEventHandler(element, 'click', function (event) {
setChecked(event.target.checked);
});
$(window.document).on('change', selector, getChecked);
ko.utils.domNodeDisposal.addDisposeCallback(element, () => {
$(window.document).off('change', selector, getChecked);
});
getChecked();
}
};
in html:
<input id="check-all-values" type="checkbox" data-bind="allChecked: '.checkValue'"/>
<input id="check-1" type="checkbox" class="checkValue"/>
<input id="check-2" type="checkbox" class="checkValue"/>
JavaScript is case-sensitive. The b
in getElementbyId
should be capitalized.
var content = document.getElementById("edit").innerHTML;
The Following command displays extra informations
curl -X POST http://httpbin.org/post -v > /dev/null
You can ask server to send just HEAD, instead of full response
curl -X HEAD -I http://httpbin.org/
Note:
In some cases, server may send different headers for POST and HEAD. But in almost all cases headers are same.
They are both quite similar in solving for the solution, but as others have said, one (Logistic Regression) is for predicting a category "fit" (Y/N or 1/0), and the other (Linear Regression) is for predicting a value.
So if you want to predict if you have cancer Y/N (or a probability) - use logistic. If you want to know how many years you will live to - use Linear Regression !
I use LuaSocket to get more precision.
require "socket"
print("Milliseconds: " .. socket.gettime()*1000)
This adds a dependency of course, but works fine for personal use (in benchmarking scripts for example).
This helped me:
<p>Date/Time: <span id="datetime"></span></p><script>var dt = new Date();
document.getElementById("datetime").innerHTML=dt.toLocaleString();</script>
I modified the /etc/sysconfig/ip6tables-config
file changing:
IP6TABLES_SAVE_ON_STOP="no"
To:
IP6TABLES_SAVE_ON_STOP="yes"
And this:
IP6TABLES_SAVE_ON_RESTART="no"
To:
IP6TABLES_SAVE_ON_RESTART="yes"
This seemed to save the changes I made using the iptables commands through a reboot.
I don't think it's necessary to use semi-quotes around the variables, try:
curl -XPOST 'http://localhost/Service' -d "path=%2fxyz%2fpqr%2ftest%2f&fileName=1.doc"
%2f
is the escape code for a /
.

Also, do you need to specify a port? ( just checking :) )
UPDATE: The image size Must be larger than (600 x 315px)
The image size can be any size because Faceboook re-size the image width & height.
The default height is 208px

According to the Android developers guide for android.hardware.Camera
, they state:
We recommend using the new android.hardware.camera2 API for new applications.
On the information page about android.hardware.camera2
, (linked above), it is stated:
The android.hardware.camera2 package provides an interface to individual camera devices connected to an Android device. It replaces the deprecated Camera class.
When you check that documentation you'll find that the implementation of these 2 Camera API's are very different.
For example getting camera orientation on android.hardware.camera
@Override
public int getOrientation(final int cameraId) {
Camera.CameraInfo info = new Camera.CameraInfo();
Camera.getCameraInfo(cameraId, info);
return info.orientation;
}
Versus android.hardware.camera2
@Override
public int getOrientation(final int cameraId) {
try {
CameraManager manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
String[] cameraIds = manager.getCameraIdList();
CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
} catch (CameraAccessException e) {
// TODO handle error properly or pass it on
return 0;
}
}
This makes it hard to switch from one to another and write code that can handle both implementations.
Note that in this single code example I already had to work around the fact that the olde camera API works with int
primitives for camera IDs while the new one works with String
objects. For this example I quickly fixed that by using the int as an index in the new API. If the camera's returned aren't always in the same order this will already cause issues. Alternative approach is to work with String objects and String representation of the old int cameraIDs which is probably safer.
Now to work around this huge difference you can implement an interface first and reference that interface in your code.
Here I'll list some code for that interface and the 2 implementations. You can limit the implementation to what you actually use of the camera API to limit the amount of work.
In the next section I'll quickly explain how to load one or another.
The interface wrapping all you need, to limit this example I only have 2 methods here.
public interface CameraSupport {
CameraSupport open(int cameraId);
int getOrientation(int cameraId);
}
Now have a class for the old camera hardware api:
@SuppressWarnings("deprecation")
public class CameraOld implements CameraSupport {
private Camera camera;
@Override
public CameraSupport open(final int cameraId) {
this.camera = Camera.open(cameraId);
return this;
}
@Override
public int getOrientation(final int cameraId) {
Camera.CameraInfo info = new Camera.CameraInfo();
Camera.getCameraInfo(cameraId, info);
return info.orientation;
}
}
And another one for the new hardware api:
public class CameraNew implements CameraSupport {
private CameraDevice camera;
private CameraManager manager;
public CameraNew(final Context context) {
this.manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
}
@Override
public CameraSupport open(final int cameraId) {
try {
String[] cameraIds = manager.getCameraIdList();
manager.openCamera(cameraIds[cameraId], new CameraDevice.StateCallback() {
@Override
public void onOpened(CameraDevice camera) {
CameraNew.this.camera = camera;
}
@Override
public void onDisconnected(CameraDevice camera) {
CameraNew.this.camera = camera;
// TODO handle
}
@Override
public void onError(CameraDevice camera, int error) {
CameraNew.this.camera = camera;
// TODO handle
}
}, null);
} catch (Exception e) {
// TODO handle
}
return this;
}
@Override
public int getOrientation(final int cameraId) {
try {
String[] cameraIds = manager.getCameraIdList();
CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
} catch (CameraAccessException e) {
// TODO handle
return 0;
}
}
}
Now to load either your CameraOld
or CameraNew
class you'll have to check the API level since CameraNew
is only available from api level 21.
If you have dependency injection set up already you can do so in your module when providing the CameraSupport
implementation. Example:
@Module public class CameraModule {
@Provides
CameraSupport provideCameraSupport(){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
return new CameraNew(context);
} else {
return new CameraOld();
}
}
}
If you don't use DI you can just make a utility or use Factory pattern to create the proper one. Important part is that the API level is checked.

Use NuGet (VS 2013+):
The easiest way in any recent version of Visual Studio is to just use the NuGet package manager. (Even VS2013, with the NuGet Package Manager for Visual Studio 2013 extension.)
Right-click on "References" and choose "Manage NuGet Packages...", then just search for Excel.
VS 2012:
Older versions of VS didn't have access to NuGet.

.The correct answer is usually to use require, but in a few cases it's not possible.
The following code will do the trick, but use it with care:
var fs = require('fs');
var vm = require('vm');
var includeInThisContext = function(path) {
var code = fs.readFileSync(path);
vm.runInThisContext(code, path);
}.bind(this);
includeInThisContext(__dirname+"/models/car.js");
If you would like to auto format on save just with Javascript source, add this one into Users Setting
(press Cmd, or Ctrl,):
"[javascript]": { "editor.formatOnSave": true }
Using jQuery:
$('#link_other a').each(function(){
$(this).attr('target', '_BLANK');
});
Other answers are correct to suggest Sort
, but they seem to have missed the fact that the storage location is typed as IList<string
. Sort
is not part of the interface.
If you know that ListaServizi
will always contain a List<string>
, you can either change its declared type, or use a cast. If you're not sure, you can test the type:
if (typeof(List<string>).IsAssignableFrom(ListaServizi.GetType()))
((List<string>)ListaServizi).Sort();
else
{
//... some other solution; there are a few to choose from.
}
Perhaps more idiomatic:
List<string> typeCheck = ListaServizi as List<string>;
if (typeCheck != null)
typeCheck.Sort();
else
{
//... some other solution; there are a few to choose from.
}
If you know that ListaServizi
will sometimes hold a different implementation of IList<string>
, leave a comment, and I'll add a suggestion or two for sorting it.
In pyspark,SparkSql syntax:
where column_n like 'xyz%'
might not work.
Use:
where column_n RLIKE '^xyz'
This works perfectly fine.
If numpy >= 1.5
, you can do:
# note that the filename is enclosed with double quotes,
# example "filename.txt"
numpy.savetxt("filename", a, newline=" ")
Edit
several 1D arrays with same length
a = numpy.array([1,2,3])
b = numpy.array([4,5,6])
numpy.savetxt(filename, (a,b), fmt="%d")
# gives:
# 1 2 3
# 4 5 6
several 1D arrays with variable length
a = numpy.array([1,2,3])
b = numpy.array([4,5])
with open(filename,"w") as f:
f.write("\n".join(" ".join(map(str, x)) for x in (a,b)))
# gives:
# 1 2 3
# 4 5
Here is the regex for the Internet Email Address using the RegularExpressionValidator in .NET
\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
By the way if you put a RegularExpressionValidator on the page and go to the design view there is a ValidationExpression field that you can use to choose from a list of expressions provided by .NET. Once you choose the expression you want there is a Validation expression: textbox that holds the regex used for the validator
This has a regular expression so it's easier to just copy and paste the youtube url. Is great for when you use a CMS for clients.

I'm not sure what you're trying to do, but here's something to consider: c();
won't do anything. c
is an instance of the class checkbox
and not a method to be called. So consider this:
public class FirstWindow extends JFrame { public FirstWindow() { checkbox c = new checkbox(); c.yourMethod(yourParameters); // call the method you made in checkbox } } public class checkbox extends JFrame { public checkbox(yourParameters) { // this is the constructor method used to initialize instance variables } public void yourMethod() // doesn't have to be void { // put your code here } }
Although Reed Copsey and Marc Gravell already described about IQueryable
(and also IEnumerable
) enough,mI want to add little more here by providing a small example on IQueryable
and IEnumerable
as many users asked for it
Example: I have created two table in database
CREATE TABLE [dbo].[Employee]([PersonId] [int] NOT NULL PRIMARY KEY,[Gender] [nchar](1) NOT NULL)
CREATE TABLE [dbo].[Person]([PersonId] [int] NOT NULL PRIMARY KEY,[FirstName] [nvarchar](50) NOT NULL,[LastName] [nvarchar](50) NOT NULL)
The Primary key(PersonId
) of table Employee
is also a forgein key(personid
) of table Person
Next i added ado.net entity model in my application and create below service class on that
public class SomeServiceClass
{
public IQueryable<Employee> GetEmployeeAndPersonDetailIQueryable(IEnumerable<int> employeesToCollect)
{
DemoIQueryableEntities db = new DemoIQueryableEntities();
var allDetails = from Employee e in db.Employees
join Person p in db.People on e.PersonId equals p.PersonId
where employeesToCollect.Contains(e.PersonId)
select e;
return allDetails;
}
public IEnumerable<Employee> GetEmployeeAndPersonDetailIEnumerable(IEnumerable<int> employeesToCollect)
{
DemoIQueryableEntities db = new DemoIQueryableEntities();
var allDetails = from Employee e in db.Employees
join Person p in db.People on e.PersonId equals p.PersonId
where employeesToCollect.Contains(e.PersonId)
select e;
return allDetails;
}
}
they contains same linq. It called in program.cs
as defined below
class Program
{
static void Main(string[] args)
{
SomeServiceClass s= new SomeServiceClass();
var employeesToCollect= new []{0,1,2,3};
//IQueryable execution part
var IQueryableList = s.GetEmployeeAndPersonDetailIQueryable(employeesToCollect).Where(i => i.Gender=="M");
foreach (var emp in IQueryableList)
{
System.Console.WriteLine("ID:{0}, EName:{1},Gender:{2}", emp.PersonId, emp.Person.FirstName, emp.Gender);
}
System.Console.WriteLine("IQueryable contain {0} row in result set", IQueryableList.Count());
//IEnumerable execution part
var IEnumerableList = s.GetEmployeeAndPersonDetailIEnumerable(employeesToCollect).Where(i => i.Gender == "M");
foreach (var emp in IEnumerableList)
{
System.Console.WriteLine("ID:{0}, EName:{1},Gender:{2}", emp.PersonId, emp.Person.FirstName, emp.Gender);
}
System.Console.WriteLine("IEnumerable contain {0} row in result set", IEnumerableList.Count());
Console.ReadKey();
}
}
The output is same for both obviously
ID:1, EName:Ken,Gender:M
ID:3, EName:Roberto,Gender:M
IQueryable contain 2 row in result set
ID:1, EName:Ken,Gender:M
ID:3, EName:Roberto,Gender:M
IEnumerable contain 2 row in result set
So the question is what/where is the difference? It does not seem to have any difference right? Really!!
Let's have a look on sql queries generated and executed by entity framwork 5 during these period
IQueryable execution part
--IQueryableQuery1
SELECT
[Extent1].[PersonId] AS [PersonId],
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE ([Extent1].[PersonId] IN (0,1,2,3)) AND (N'M' = [Extent1].[Gender])
--IQueryableQuery2
SELECT
[GroupBy1].[A1] AS [C1]
FROM ( SELECT
COUNT(1) AS [A1]
FROM [dbo].[Employee] AS [Extent1]
WHERE ([Extent1].[PersonId] IN (0,1,2,3)) AND (N'M' = [Extent1].[Gender])
) AS [GroupBy1]
IEnumerable execution part
--IEnumerableQuery1
SELECT
[Extent1].[PersonId] AS [PersonId],
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE [Extent1].[PersonId] IN (0,1,2,3)
--IEnumerableQuery2
SELECT
[Extent1].[PersonId] AS [PersonId],
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE [Extent1].[PersonId] IN (0,1,2,3)
Common script for both execution part
/* these two query will execute for both IQueryable or IEnumerable to get details from Person table
Ignore these two queries here because it has nothing to do with IQueryable vs IEnumerable
--ICommonQuery1
exec sp_executesql N'SELECT
[Extent1].[PersonId] AS [PersonId],
[Extent1].[FirstName] AS [FirstName],
[Extent1].[LastName] AS [LastName]
FROM [dbo].[Person] AS [Extent1]
WHERE [Extent1].[PersonId] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=1
--ICommonQuery2
exec sp_executesql N'SELECT
[Extent1].[PersonId] AS [PersonId],
[Extent1].[FirstName] AS [FirstName],
[Extent1].[LastName] AS [LastName]
FROM [dbo].[Person] AS [Extent1]
WHERE [Extent1].[PersonId] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=3
*/
So you have few questions now, let me guess those and try to answer them
Why are different scripts generated for same result?
Lets find out some points here,
all queries has one common part
WHERE [Extent1].[PersonId] IN (0,1,2,3)
why? Because both function IQueryable<Employee> GetEmployeeAndPersonDetailIQueryable
and
IEnumerable<Employee> GetEmployeeAndPersonDetailIEnumerable
of SomeServiceClass
contains one common line in linq queries
where employeesToCollect.Contains(e.PersonId)
Than why is the
AND (N'M' = [Extent1].[Gender])
part is missing in IEnumerable
execution part, while in both function calling we used Where(i => i.Gender == "M") in
program.cs`
Now we are in the point where difference came between
IQueryable
andIEnumerable
What entity framwork does when an IQueryable
method called, it tooks linq statement written inside the method and try to find out if more linq expressions are defined on the resultset, it then gathers all linq queries defined until the result need to fetch and constructs more appropriate sql query to execute.
It provide a lots of benefits like,
like here in example sql server returned to application only two rows after IQueryable execution` but returned THREE rows for IEnumerable query why?
In case of IEnumerable
method, entity framework took linq statement written inside the method and constructs sql query when result need to fetch. it does not include rest linq part to constructs the sql query. Like here no filtering is done in sql server on column gender
.
But the outputs are same? Because 'IEnumerable filters the result further in application level after retrieving result from sql server
SO, what should someone choose?
I personally prefer to define function result as IQueryable<T>
because there are lots of benefit it has over IEnumerable
like, you could join two or more IQueryable functions, which generate more specific script to sql server.
Here in example you can see an IQueryable Query(IQueryableQuery2)
generates a more specific script than IEnumerable query(IEnumerableQuery2)
which is much more acceptable in my point of view.
You can fix the issue by deleting the __MigrationHistory
table which is created automatically in the database and logs any update in the database using code-first migrations. Here, in this case, you manually changed your database while EF assumed you had to do it with the migration tool. Deleting the table means to the EF that there are no updates and no need to do code-first migrations thus it works perfectly fine.
try this out let me know what happens.
Form:
<form action="form.php" method="post">
Search: <input type="text" name="term" /><br />
<input type="submit" value="Submit" />
</form>
Form.php:
$term = mysql_real_escape_string($_REQUEST['term']);
$sql = "SELECT * FROM liam WHERE Description LIKE '%".$term."%'";
$r_query = mysql_query($sql);
while ($row = mysql_fetch_array($r_query)){

Edit: Cleaned it up a little more.
Final Cut (my test file):

Read Initial password :
C:\Program Files(x86)\Jenkins\secrets\initialAdminPassword
Default username is 'admin' and the password is the one from initialAdminPassword when you follow the above path.
'Manage Jenkins' --> 'Manage Users' --> Password
Then logout and login to make sure new password works.
You are missing setting what field is the Text and Value in the SelectList itself. That is why it does a .ToString()
on each object in the list. You could think that given it is a list of SelectListItem
it should be smart enough to detect this... but it is not.
u.UserTypeOptions = new SelectList(
new List<SelectListItem>
{
new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
new SelectListItem { Selected = false, Text = "Homeowner", Value = ((int)UserType.Homeowner).ToString()},
new SelectListItem { Selected = false, Text = "Contractor", Value = ((int)UserType.Contractor).ToString()},
}, "Value" , "Text", 1);
BTW, you can use a list of array of any type... and then just set the name of the properties that will act as Text and Value.
I think it is better to do it like this:
u.UserTypeOptions = new SelectList(
new List<SelectListItem>
{
new SelectListItem { Text = "Homeowner", Value = ((int)UserType.Homeowner).ToString()},
new SelectListItem { Text = "Contractor", Value = ((int)UserType.Contractor).ToString()},
}, "Value" , "Text");
I removed the -1 item, and the setting of each items selected true/false.
Then, in your view:
@Html.DropDownListFor(m => m.UserType, Model.UserTypeOptions, "Select one")
This way, if you set the "Select one" item, and you don't set one item as selected in the SelectList, the UserType
will be null (the UserType
need to be int?
).
If you need to set one of the SelectList items as selected, you can use:
u.UserTypeOptions = new SelectList(options, "Value" , "Text", userIdToBeSelected);
This is just another example of how you can use Dropzone.js in an existing form.
dropzone.js :
init: function() {
this.on("success", function(file, responseText) {
//alert("HELLO ?" + responseText);
mylittlefix(responseText);
});
return noop;
},
Then, later in the file I put
function mylittlefix(responseText) {
$('#botofform').append('<input type="hidden" name="files[]" value="'+ responseText +'">');
}
This assumes you have a div with id #botofform
that way when uploading you can use the uploaded files' names.
Note: my upload script returned theuploadedfilename.jpeg dubblenote you also would need to make a cleanup script that checks the upload directory for files not in use and deletes them ..if in a front end non authenticated form :)
What you need to do is use the onchange
event listener in the form and change the href

Page -- Takes the specified XAML file, and compiles into BAML, and embeds that output into the managed resource stream for your assembly (specifically AssemblyName.g.resources), Additionally, if you have the appropriate attributes on the root XAML element in the file, it will create a blah.g.cs file, which will contain a partial class of the "codebehind" for that page; this basically involves a call to the BAML goop to re-hydrate the file into memory, and to set any of the member variables of your class to the now-created items (e.g. if you put x:Name="foo" on an item, you'll be able to do this.foo.Background = Purple; or similar.
ApplicationDefinition -- similar to Page, except it goes onestep furthur, and defines the entry point for your application that will instantiate your app object, call run on it, which will then instantiate the type set by the StartupUri property, and will give your mainwindow.
Also, to be clear, this question overall is infinate in it's results set; anyone can define additional BuildActions just by building an MSBuild Task. If you look in the %systemroot%\Microsoft.net\framework\v{version}\ directory, and look at the Microsoft.Common.targets file, you should be able to decipher many more (example, with VS Pro and above, there is a "Shadow" action that allows you generate private accessors to help with unit testing private classes.

Steveha's answer was helpful to me, but omits an important point (one that I think wisty was getting at). The global keyword is not necessary if you only access but do not assign the variable in the function.
If you assign the variable without the global keyword then Python creates a new local var -- the module variable's value will now be hidden inside the function. Use the global keyword to assign the module var inside a function.
Pylint 1.3.1 under Python 2.7 enforces NOT using global if you don't assign the var.
module_var = '/dev/hello'
def readonly_access():
connect(module_var)
def readwrite_access():
global module_var
module_var = '/dev/hello2'
connect(module_var)
Most of the cases like getting query string or form parameters are covered in answers above.
When working with raw data, like a raw JSON string in the body that you would like to give as an argument to json_decode()
, the method Request::getContent()
can be used.
$content = $request->getContent();
Additional useful informations on HTTP requests in Symfony can be found on the HttpFoundation package's documentation.
Please note that 4.0 is not sufficient since ListValuedMap, was introduced in version 4.1.
You need to use this maven repository link for version 4.1. Replicated below for convenience

There is an easier way to fix this issue with Mac OS and Homebrew:
Install homebrew if it is not installed yet
$brew install libpng
$pngfix --strip=color --out=file2.png file.png
or to do it with every file in the current directory:
mkdir tmp; for f in ./*.png; do pngfix --strip=color --out=tmp/"$f" "$f"; done
It will create a fixed copy for each png file in the current directory and put it in the the tmp subdirectory. After that, if everything is OK, you just need to override the original files.
Another tip is to use the Keynote and Preview applications to create the icons. I draw them using Keynote, in the size of about 120x120 pixels, over a slide with a white background (the option to make polygons editable is great!). Before exporting to Preview, I draw a rectangle around the icon (without any fill or shadow, just the outline, with the size of about 135x135) and copy everything to the clipboard. After that, you just need to open it with the Preview tool using "New from Clipboard", select a 128x128 pixels area around the icon, copy, use "New from Clipboard" again, and export it to PNG. You won't need to run the pngfix tool.

Almost all methods needs to specify the height, but often we don't have any heights.
So here is a CSS3 3 line trick that doesn't require to know the height.
.element {
position: relative;
top: 50%;
transform: translateY(-50%);
}
It's supported even in IE9.
with its vendor prefixes:
.element {
position: relative;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
}

Use Assembly.GetTypes
. For example:
Assembly mscorlib = typeof(string).Assembly;
foreach (Type type in mscorlib.GetTypes())
{
Console.WriteLine(type.FullName);
}
You're thinking too DOM, it's a hard as hell habit to break. Vue recommends you approach it data first.
It's kind of hard to tell in your exact situation but I'd probably use a v-for
and make an array of finds
to push to as I need more.
Here's how I'd set up my instance:
new Vue({
el: '#app',
data: {
finds: []
},
methods: {
addFind: function () {
this.finds.push({ value: '' });
}
}
});
And here's how I'd set up my template:
<div id="app">
<h1>Finds</h1>
<div v-for="(find, index) in finds">
<input v-model="find.value" :key="index">
</div>
<button @click="addFind">
New Find
</button>
</div>
Although, I'd try to use something besides an index
for the key
.
Here's a demo of the above: https://jsfiddle.net/crswll/24txy506/9/
C++11 added alias declarations, which are generalization of typedef
, allowing templates:
template <size_t N>
using Vector = Matrix<N, 1>;
The type Vector<3>
is equivalent to Matrix<3, 1>
.
In C++03, the closest approximation was:
template <size_t N>
struct Vector
{
typedef Matrix<N, 1> type;
};
Here, the type Vector<3>::type
is equivalent to Matrix<3, 1>
.
ArrayList<Customer> custArr = new ArrayList<Customer>();
while(youWantToContinue) {
//get a customerName
//get an amount
custArr.add(new Customer(customerName, amount);
}
For this to work... you'll have to fix your constructor...
Assuming your Customer
class has variables called name
and sale
, your constructor should look like this:
public Customer(String customerName, double amount) {
name = customerName;
sale = amount;
}
Change your Store
class to something more like this:
public class Store {
private ArrayList<Customer> custArr;
public new Store() {
custArr = new ArrayList<Customer>();
}
public void addSale(String customerName, double amount) {
custArr.add(new Customer(customerName, amount));
}
public Customer getSaleAtIndex(int index) {
return custArr.get(index);
}
//or if you want the entire ArrayList:
public ArrayList getCustArr() {
return custArr;
}
}
<?php
$stop_date = '2009-09-30 20:24:00';
echo 'date before day adding: ' . $stop_date;
$stop_date = date('Y-m-d H:i:s', strtotime($stop_date . ' +1 day'));
echo 'date after adding 1 day: ' . $stop_date;
?>
For PHP 5.2.0+, you may also do as follows:
$stop_date = new DateTime('2009-09-30 20:24:00');
echo 'date before day adding: ' . $stop_date->format('Y-m-d H:i:s');
$stop_date->modify('+1 day');
echo 'date after adding 1 day: ' . $stop_date->format('Y-m-d H:i:s');
Let's first look at the definitions of these words before evaluating what the difference is in HTML:
English definition:
In HTML context:
When the browser parses the HTML, it creates a tree data structure wich basically is an in memory representation of the HTML. It the tree data structure contains nodes which are HTML elements and text. Attributes and properties relate to this is the following manner:
It is also important to realize that the mapping of these properties is not 1 to 1. In other words, not every attribute which we give on an HTML element will have a similar named DOM property.
Furthermore have different DOM elements different properties. For example, an <input>
element has a value property which is not present on a <div>
property.
Let's take the following HTML document:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"> <!-- charset is a attribute -->
<meta name="viewport" content="width=device-width"> <!-- name and content are attributes -->
<title>JS Bin</title>
</head>
<body>
<div id="foo" class="bar foobar">hi</div> <!-- id and class are attributes -->
</body>
</html>
Then we inspect the <div>
, in the JS console:
console.dir(document.getElementById('foo'));
We see the following DOM properties (chrome devtools, not all properties shown):
class
is reserved keyword in JS). But actually 2 properties, classList
and className
.Try in this way -
public class SummaryMapActivity extends FragmentActivity implements LocationListener{
private GoogleMap mMap;
private LocationManager locationManager;
private static final long MIN_TIME = 400;
private static final float MIN_DISTANCE = 1000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.summary_mapview);
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null) {
mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
}
}
mMap.setMyLocationEnabled(true);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME, MIN_DISTANCE, this);
}
@Override
public void onLocationChanged(Location location) {
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 15);
mMap.animateCamera(cameraUpdate);
locationManager.removeUpdates(this);
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}
Update (using renderer):
Note that the original Renderer service has now been deprecated in favor of Renderer2
as on Renderer2 official doc.
Furthermore, as pointed out by @GünterZöchbauer:
Actually using ElementRef is just fine. Also using ElementRef.nativeElement with Renderer2 is fine. What is discouraged is accessing properties of ElementRef.nativeElement.xxx directly.
You can achieve this by using elementRef
as well as by ViewChild
. however it's not recommendable to use elementRef
due to:
as pointed out by official ng2 documentation.
elementRef
(Direct Access):export class MyComponent {
constructor (private _elementRef : ElementRef) {
this._elementRef.nativeElement.querySelector('textarea').focus();
}
}
ViewChild
(better approach):<textarea #tasknote name="tasknote" [(ngModel)]="taskNote" placeholder="{{ notePlaceholder }}"
style="background-color: pink" (blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }} </textarea> // <-- changes id to local var
export class MyComponent implements AfterViewInit {
@ViewChild('tasknote') input: ElementRef;
ngAfterViewInit() {
this.input.nativeElement.focus();
}
}
renderer
:export class MyComponent implements AfterViewInit {
@ViewChild('tasknote') input: ElementRef;
constructor(private renderer: Renderer2){
}
ngAfterViewInit() {
//using selectRootElement instead of depreaced invokeElementMethod
this.renderer.selectRootElement(this.input["nativeElement"]).focus();
}
}
By using jquery ajax you can reload your page
$.ajax({
type: "POST",
url: "packtypeAdd.php",
data: infoPO,
success: function() {
location.reload();
}
});
A non-JIT compiler takes source code and transforms it into machine specific byte code at compile time. A JIT compiler takes machine agnostic byte code that was generated at compile time and transforms it into machine specific byte code at run time. The JIT compiler that Java uses is what allows a single binary to run on a multitude of platforms without modification.
One way is to optional
like described in the accepted answer: https://stackoverflow.com/a/62566052/1803821
Another one is to use wrapper objects. You don't need to write them yourself as google already provides them:
At the top of your .proto file add this import:
import "google/protobuf/wrappers.proto";
Now you can use special wrappers for every simple type:
DoubleValue
FloatValue
Int64Value
UInt64Value
Int32Value
UInt32Value
BoolValue
StringValue
BytesValue
So to answer the original question a usage of such a wrapper could be like this:
message Foo {
int32 bar = 1;
google.protobuf.Int32Value baz = 2;
}
Now for example in Java I can do stuff like:
if(foo.hasBaz()) { ... }
Use some tag, to aligning the input element. So
<form>
<div>
<input>
<br />
<input>
</div>
</form>
.mydiv
{
width: 500px;
height: 250px;
display: table;
text-align: right;
}
Please refer this answer on the actual need for pre-flighted OPTIONS request: CORS - What is the motivation behind introducing preflight requests?

, or text/plain

Do not write tests for private methods. This defeats the point of unit tests.
Example
class SomeClass {
public addNumber(a: number, b: number) {
return a + b;
}
}
The test for this method should not need to change if later the implementation changes but the behaviour
of the public API remains the same.
class SomeClass {
public addNumber(a: number, b: number) {
return this.add(a, b);
}
private add(a: number, b: number) {
return a + b;
}
}
Don't make methods and properties public just in order to test them. This usually means that either:
What ultimately worked for me was the following steps:
I used this one
select DATE_ADD(DATE_SUB(LAST_DAY(now()), INTERVAL 1 MONTH),INTERVAL 1 day) first_day
,LAST_DAY(now()) last_day, date(now()) today_day
According to me, Spring doesn't handle all the cases with ease. In your case the following should do the trick
Page<QueuedBook> findByBookIdRegion(Region region, Pageable pageable);
or
Page<QueuedBook> findByBookId_Region(Region region, Pageable pageable);
However, it also depends on the naming convention of fields that you have in your @Embeddable
class,
e.g. the following field might not work in any of the styles that mentioned above
private String cRcdDel;
I tried with both the cases (as follows) and it didn't work (it seems like Spring doesn't handle this type of naming conventions(i.e. to many Caps , especially in the beginning - 2nd letter (not sure about if this is the only case though)
Page<QueuedBook> findByBookIdCRcdDel(String cRcdDel, Pageable pageable);
or
Page<QueuedBook> findByBookIdCRcdDel(String cRcdDel, Pageable pageable);
When I renamed column to
private String rcdDel;
my following solutions work fine without any issue:
Page<QueuedBook> findByBookIdRcdDel(String rcdDel, Pageable pageable);
OR
Page<QueuedBook> findByBookIdRcdDel(String rcdDel, Pageable pageable);
Here's my solution (in Spring with Thymeleaf and jQuery):

Instead of parsing day, month and year you can specify date formats directly using datepicker's formatDate function. In my example I am using "yy-mm-dd", but you can use any format of your choice.
$("#datepicker").datepicker({
dateFormat: 'yy-mm-dd',
inline: true,
minDate: new Date(2010, 1 - 1, 1),
maxDate: new Date(2010, 12 - 1, 31),
altField: '#datepicker_value',
onSelect: function(){
var fullDate = $.datepicker.formatDate("yy-mm-dd", $(this).datepicker('getDate'));
var str_output = "<h1><center><img src=\"/images/a" + fullDate +".png\"></center></h1><br/><br>";
$('#page_output').html(str_output);
}
});
html body {
background: url(/assets/images/header-bg.jpg) no-repeat top center fixed;
width: 100%;
height: 100%;
min-width: 100%;
min-height: 100%;
-webkit-background-size: auto auto;
-moz-background-size: auto auto;
-o-background-size: auto auto;

That means a new line is printed.
As a side note there is no need to write that extra line . There is an built in inbuilt function there.
println() //prints the content in new line

As you have to use WITH (NOLOCK) for each table it might be annoying to write it in every FROM or JOIN clause. However it has a reason why it is called a "dirty" read. So you really should know when you do one, and not set it as default for the session scope. Why?
Forgetting a WITH (NOLOCK) might not affect your program in a very dramatic way, however doing a dirty read where you do not want one can make the difference in certain circumstances.
So use WITH (NOLOCK) if the current data selected is allowed to be incorrect, as it might be rolled back later. This is mostly used when you want to increase performance, and the requirements on your application context allow it to take the risk that inconsistent data is being displayed. However you or someone in charge has to weigh up pros and cons of the decision of using WITH (NOLOCK).
The formatting can be done like this (I assumed you meant HH:MM instead of HH:SS, but it's easy to change):
Time.now.strftime("%d/%m/%Y %H:%M")
#=> "14/09/2011 14:09"
Updated for the shifting:
d = DateTime.now
d.strftime("%d/%m/%Y %H:%M")
#=> "11/06/2017 18:11"
d.next_month.strftime("%d/%m/%Y %H:%M")
#=> "11/07/2017 18:11"
You need to require 'date'
for this btw.
The message from Linus Torvalds may answer your question:
Modify/edit old commit messages
Short answer: you can not (if pushed).
extract (Linus refers to BitKeeper as BK):
Side note, just out of historical interest: in BK you could.
And if you're used to it (like I was) it was really quite practical. I would apply a patch-bomb from Andrew, notice something was wrong, and just edit it before pushing it out.
I could have done the same with git. It would have been easy enough to make just the commit message not be part of the name, and still guarantee that the history was untouched, and allow the "fix up comments later" thing.
But I didn't.
Part of it is purely "internal consistency". Git is simply a cleaner system thanks to everything being SHA1-protected, and all objects being treated the same, regardless of object type. Yeah, there are four different kinds of objects, and they are all really different, and they can't be used in the same way, but at the same time, even if their encoding might be different on disk, conceptually they all work exactly the same.
But internal consistency isn't really an excuse for being inflexible, and clearly it would be very flexible if we could just fix up mistakes after they happen. So that's not a really strong argument.
The real reason git doesn't allow you to change the commit message ends up being very simple: that way, you can trust the messages. If you allowed people to change them afterwards, the messages are inherently not very trustworthy.
To be complete, you could rewrite your local commit history in order to reflect what you want, as suggested by sykora (with some rebase and reset --hard, gasp!)
However, once you publish your revised history again (with a git push origin +master:master
, the +
sign forcing the push to occur, even if it doesn't result in a "fast-forward" commit)... you might get into some trouble.
Extract from this other SO question:
I actually once pushed with --force to git.git repository and got scolded by Linus BIG TIME. It will create a lot of problems for other people. A simple answer is "don't do it".

To address this question from a different perspective for newer programmers:
Inheritance is often taught early when we learn object-oriented programming, so it's seen as an easy solution to a common problem.
I have three classes that all need some common functionality. So if I write a base class and have them all inherit from it, then they will all have that functionality and I'll only need to maintain it in once place.
It sounds great, but in practice it almost never, ever works, for one of several reasons:
In the end, we tie our code in some difficult knots and get no benefit whatsoever from it except that we get to say, "Cool, I learned about inheritance and now I used it." That's not meant to be condescending because we've all done it. But we all did it because no one told us not to.
As soon as someone explained "favor composition over inheritance" to me, I thought back over every time I tried to share functionality between classes using inheritance and realized that most of the time it didn't really work well.
The antidote is the Single Responsibility Principle. Think of it as a constraint. My class must do one thing. I must be able to give my class a name that somehow describes that one thing it does. (There are exceptions to everything, but absolute rules are sometimes better when we're learning.) It follows that I cannot write a base class called ObjectBaseThatContainsVariousFunctionsNeededByDifferentClasses
. Whatever distinct functionality I need must be in its own class, and then other classes that need that functionality can depend on that class, not inherit from it.
At the risk of oversimplifying, that's composition - composing multiple classes to work together. And once we form that habit we find that it's much more flexible, maintainable, and testable than using inheritance.
Add condition in Click event to restrict the clickable area .
$('#thing').click(function(e) {
if (e.clientX > $(this).offset().left + 90 &&
e.clientY < $(this).offset().top + 10) {
// action when clicking on after-element
// your code here
}
});
Simply just do something like this:
li {
cursor: pointer;
}
I apply it on your code to see how it works:
li {_x000D_
cursor: pointer;_x000D_
}
_x000D_
<ul>_x000D_
<li>foo</li>_x000D_
<li>goo</li>_x000D_
</ul>
_x000D_
Note: Also DO not forget you can have any hand cursor with customised cursor, you can create fav hand icon like this one for example:
div {_x000D_
display: block;_x000D_
width: 400px;_x000D_
height: 400px;_x000D_
background: red;_x000D_
cursor: url(http://findicons.com/files/icons/1840/free_style/128/hand.png) 4 12, auto;_x000D_
}
_x000D_
<div>_x000D_
</div>
_x000D_
You can try using the following code to solve your problem:
<activity
android:name=".DonateNow"
android:label="@string/title_activity_donate_now"
android:screenOrientation="portrait"
android:theme="@style/AppTheme"
android:windowSoftInputMode="stateVisible|adjustPan">
</activity>
Use:
if (containerObject.has("video")) {
//get value of video
}
If you want to extract from a
tag then
$('.dep_buttons').text().substr(0,25)
With the mouseover event,
$(this).text($(this).text().substr(0, 25));
The above will extract the text of a tag, then extract again assign it back.
Regex is a very bad choice for this kind of task. Try to find a web service or an address database or a product which can clean address data instead.

cmd.Parameters.Add(String parameterName, Object value)

There is no difference in terms of functionality. The reason they deprecated the
cmd.Parameters.Add(String parameterName, Object value)
in favor ofAddWithValue(String parameterName, Object value)
is to give more clarity. Here is the MSDN reference for the same
private void button1_Click(object sender, EventArgs e) {
using (SqlConnection con = new SqlConnection(dc.Con)) {
using (SqlCommand cmd = new SqlCommand("sp_Add_contact", con)) {
cmd.CommandType = CommandType.StoredProcedure;

Add the following lines to the [alias] section of your .gitconfig file
ignore = update-index --assume-unchanged
unignore = update-index --no-assume-unchanged
ignored = !git ls-files -v | grep "^[[:lower:]]"
Now you can use git ignore my_file
to ignore changes to the local file, and git unignore my_file
to stop ignoring the changes. git ignored
lists the ignored files.
This answer was gleaned from http://gitready.com/intermediate/2009/02/18/temporarily-ignoring-files.html.
Deep copy literally performs a deep copy. It means, that if your class has some fields that are references, their values will be copied, not references themselves. If, for example you have two instances of a class, A & B with fields of reference type, and perform a deep copy, changing a value of that field in A won't affect a value in B. And vise-versa. Things are different with shallow copy, because only references are copied, therefore, changing this field in a copied object would affect the original object.
What type of a copy does a copy constructor does?
It is implementation - dependent. This means that there are no strict rules about that, you can implement it like a deep copy or shallow copy, however as far as i know it is a common practice to implement a deep copy in a copy constructor. A default copy constructor performs a shallow copy though.
That's generally controlled by the profile associated with the user Tomcat is connecting as.
SQL> SELECT PROFILE, LIMIT FROM DBA_PROFILES WHERE RESOURCE_NAME = 'IDLE_TIME';
PROFILE LIMIT
------------------------------ ----------------------------------------
DEFAULT UNLIMITED
SQL> SELECT PROFILE FROM DBA_USERS WHERE USERNAME = USER;
PROFILE
------------------------------
DEFAULT
So the user I'm connected to has unlimited idle time - no time out.
I had my files at the correct places, and just removing <scope>test</scope>
from the JUnit dependency entry solved the problem (I am using JUnit 4.12). I believe that with the test
scope the dependency was just being ignored during the compilation phase. Now everything is working even when I call mvn test
.
select
Field1, Field2...
from
Table1
order by
isnumeric(Field1) desc,
case when isnumeric(Field1) = 1 then cast(Field1 as int) else null end,
Field1
This will return values in the order you gave in your question.
Performance won't be too great with all that casting going on, so another approach is to add another column to the table in which you store an integer copy of the data and then sort by that first and then the column in question. This will obviously require some changes to the logic that inserts or updates data in the table, to populate both columns. Either that, or put a trigger on the table to populate the second column whenever data is inserted or updated.
Adding on top of @VonC superb answer, here is a ZSH function that you can add into your .zshrc file:
dockstop() {
docker rm $(docker stop $(docker ps -a -q --filter ancestor="$1" --format="{{.ID}}"))
}
Then in your command line, simply do dockstop myImageName
and it will stop and remove all containers that were started from an image called myImageName.
I had the same problem. I called my own custom logger in the log4j.properties file from code when using log4j api directly. If you are using the slf4j api calls, you are probably using the default root logger so you must configure that to be associated with an appender in the log4j.properties:
# Set root logger level to DEBUG and its only appender to A1. log4j.rootLogger=DEBUG, A1 # A1 is set to be a ConsoleAppender. log4j.appender.A1=org.apache.log4j.ConsoleAppender
The most simple and native way it's to use CURL directly.
This works for me :
<?php
$login = 'login';
$password = 'password';
$url = 'http://your.url';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "$login:$password");
$result = curl_exec($ch);
curl_close($ch);
echo($result);
You can also try and use the caching built into ASP MVC:
Add the following attribute to the controller method you'd like to cache:
[OutputCache(Duration=10)]
In this case the ActionResult of this will be cached for 10 seconds.
I found the solution:
public class DefaultPostgresKeyServer
{
private Session session;
private Iterator<BigInteger> iter;
private long batchSize;
public DefaultPostgresKeyServer (Session sess, long batchFetchSize)
{
this.session=sess;
batchSize = batchFetchSize;
iter = Collections.<BigInteger>emptyList().iterator();
}
@SuppressWarnings("unchecked")
public Long getNextKey()
{
if ( ! iter.hasNext() )
{
Query query = session.createSQLQuery( "SELECT nextval( 'mySchema.mySequence' ) FROM generate_series( 1, " + batchSize + " )" );
iter = (Iterator<BigInteger>) query.list().iterator();
}
return iter.next().longValue() ;
}
}
Networks shares will drastically slow down your build, as the seek latency is high. For something like Boost, it made a huge difference for me, even though our network share drive is pretty fast. Time to compile a toy Boost program went from about 1 minute to 1 second when I switched from a network share to a local SSD.

Here is a NuGet plugin called Cassette, which among other things provides you the ability to reference scripts and styles in partials.
Though there are a number of configurations available for this plugin, which makes it highly flexible. Here is the simplest way of referring script or stylesheet files:
Bundles.Reference("scripts/app");
According to the documentation:
Calls to
Reference
can appear anywhere in a page, layout or partial view.The path argument can be one of the following:
- A bundle path
- An asset path - the whole bundle containing this asset is referenced
- A URL
Maybe this can be another solution
try
{
Console.Write("write your number : ");
Console.WriteLine("Your number is : " + int.Parse(Console.ReadLine()));
}
catch (Exception x)
{
Console.WriteLine(x.Message);
}
Console.ReadLine();
EDIT: as of Java8 you'd better use Files
class:
Path resultingPath = Files.createDirectories('A/B');
I don't know if this ultimately fixes your problem but class File
has method mkdirs()
which fully creates the path specified by the file.
File f = new File("/A/B/");
f.mkdirs();
$img_file='http://www.somedomain.com/someimage.jpg'
$img_file=file_get_contents($img_file);
$file_loc=$_SERVER['DOCUMENT_ROOT'].'/some_dir/test.jpg';
$file_handler=fopen($file_loc,'w');
if(fwrite($file_handler,$img_file)==false){
echo 'error';
}
fclose($file_handler);
That way older browser don't parse the Javascript code and the page doesn't break.
Backwards compatability. Gotta love it.
Here's another way to plot the data, involves turning the date_time into an index, this might help you for future slicing
#convert column to datetime
trip_data['lpep_pickup_datetime'] = pd.to_datetime(trip_data['lpep_pickup_datetime'])
#turn the datetime to an index
trip_data.index = trip_data['lpep_pickup_datetime']
#Plot
trip_data['Trip_distance'].plot(kind='hist')
plt.show()
If you are using jQuery you can do something like this
$('label[for="foo"]').hide ();
If you aren't using jQuery you'll have to search for the label. Here is a function that takes the element as an argument and returns the associated label
function findLableForControl(el) {
var idVal = el.id;
labels = document.getElementsByTagName('label');
for( var i = 0; i < labels.length; i++ ) {
if (labels[i].htmlFor == idVal)
return labels[i];
}
}
All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static
and I used the same STATIC_URL in my dev settings.py file.
This causes a silent failure in django/conf/urls/static.py.
The test elif not settings.DEBUG or '://' in prefix:
picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.
It would be thoughtful if Django spit out an error message stating you can't use a http(s)://
with DEBUG = True
I had to change STATIC_URL to be '/static/'
This VB.Net version works for my situation. I removed thread collection semaphore, instead using RemoveHandler and AddHandler. Also, since a FlowDocument can only be bound to one RichTextBox at a time, I put in a check that the RichTextBox's IsLoaded=True. Let's begin with how I used the class in a MVVM app which uses ResourceDictionary instead of Window.

To resolve this problem you first need to check the SSL certificates of the host your are connecting to. For example using ssllabs or other ssl tools. In my case the intermediate certificate was wrong.
If the certificate is ok, make sure the openSSL on your server is up to date. Run openssl -v
to check your version. Maybe your version is to old to work with the certificate.
In very rare cases you might want to disable ssl security features like verify_peer, verify_peer_name or allow_self_signed. Please be very careful with this and never use this in production. This is only an option for temporary testing.
When you override OnCreateView
in your RouteSearchFragment
class, do you have the
if(view != null) {
return view;
}
code segment?
If so, removing the return statement should solve your problem.
You can keep the code and return the view if you don't want to regenerate view data, and onDestroyView() method you remove this view from its parent like so:
@Override
public void onDestroyView() {
super.onDestroyView();
if (view != null) {
ViewGroup parent = (ViewGroup) view.getParent();
if (parent != null) {
parent.removeAllViews();
}
}
}

and then following methods:
def check_presence
params[:param1].present? && params[:param2].present?
end
def validate_presence
if !check_presence
render json: {
error: {
message: "Bad Request, parameters missing.",
status: 500
}
}
end
end
Since SQL 2012 you can run the following statement:
Exec sp_describe_first_result_set @tsql= N'Select * from <yourtable>'
If you enter a complex select statement (joins, subselects, etc), it will give you the definition of the result set. This is very handy, if you need to create a new table (or temp table) and you don't want to check every single field definition manually.
Don't worry so much framing the button from code, you can do that on the storyboard. This worked for me, one line...more simple.
[self.button setBackgroundImage:[UIImage imageNamed: @"yourPic.png"] forState:UIControlStateNormal];
try this:
<div style='overflow:auto; width:400px;height:400px;'>here is some text</div>
This is the universal and best solution for this:
If WScript.Arguments.Count <> 1 Then WScript.Quit 1
RunAsAdmin
Main
Sub RunAsAdmin()
Set Shell = CreateObject("WScript.Shell")
Set Env = Shell.Environment("VOLATILE")
If Shell.Run("%ComSpec% /C ""NET FILE""", 0, True) <> 0 Then
Env("CurrentDirectory") = Shell.CurrentDirectory
ArgsList = ""
For i = 1 To WScript.Arguments.Count
ArgsList = ArgsList & """ """ & WScript.Arguments(i - 1)
Next
CreateObject("Shell.Application").ShellExecute WScript.FullName, """" & WScript.ScriptFullName & ArgsList & """", , "runas", 5
WScript.Sleep 100
Env.Remove("CurrentDirectory")
WScript.Quit
End If
If Env("CurrentDirectory") <> "" Then Shell.CurrentDirectory = Env("CurrentDirectory")
End Sub
Sub Main()
'Your code here!
End Sub
Advantages:
1) The parameter injection is not possible.
2) The number of arguments does not change after the elevation to administrator and then you can check them before you elevate yourself.
3) You know for real and immediately if the script runs as an administrator. For example, if you call it from a control panel uninstallation entry, the RunAsAdmin function will not run unnecessarily because in that case you are already an administrator. Same thing if you call it from a script already elevated to administrator.
4) The window is kept at its current size and position, as it should be.
5) The current directory doesn't change after obtained administrative privileges.
Disadvantages: Nobody
The html code you written is absolutely perfect
<ul class="nav navbar-nav list-inline">
<li class="list-inline-item">FB</li>
<li class="list-inline-item">G+</li>
<li class="list-inline-item">T</li>
</ul>
The reasons that could be possible is
1. Check out the CSS for class name "nav" or "navbar-nav" may be over writing it, try to remove and debug the class names in the ul element.
2. Check any of the child element(a tag or "social-icon" class) is using block level CSS style
3. Check out your using a HTML5 !DOCTYPE html
4. Place your bootstrap.css link at the last before closing your head tag
5. Change text-xs-center to text-center because xs is dropped in Bootstrap 4.
This One will work perfectly fine
<!-- Use this inside Head tag-->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/js/bootstrap.min.js"></script>
<!-- Use this inside Body tag-->
<div class="container">
<ul class="list-inline">
<li class="list-inline-item"><a class="social-icon text-center" target="_blank" href="#">FB</a></li>
<li class="list-inline-item"><a class="social-icon text-center" target="_blank" href="#">G+</a></li>
<li class="list-inline-item"><a class="social-icon text-center" target="_blank" href="#">T</a></li>
</ul>
</div>
This error occurred for me when a value was returned as -1.#IND due to a division by zero. More info on IEEE floating-point exceptions in C++ here on SO and by John Cook
For the one who has downvoted this answer (and did not specify why), the reason why this answer can be significant to some is that a division by zero will lead to an infinitely large number and thus a value that doesn't fit in an Int32 (or even Int64). So the error you receive will be the same (Arithmetic operation resulted in an overflow) but the reason is slightly different.
Had to debug a site for native Android browser and came here. So I tried weinre on an OS X 10.9 (as weinre server) with Firefox 30.0 (weinre client) and an Android 4.1.2 (target). I'm really, really surprised of the result.
sudo npm -g install weinre
weinre --boundHost YOUR.IP.ADDRESS.HERE
http://YOUR.IP.ADRESS.HERE:8080
<script src="http://YOUR.IP.ADDRESS.HERE:8080/target/target-script-min.js"></script>
Maybe 8080 isn't your default port. Then in step 4 you have to call weinre --httpPort YOURPORT --boundHost YOUR.IP.ADRESS.HERE
.
And I don't remember exactly when it was, maybe somewhere after step 5, I had to accept incoming connections prompt, of course.
Happy debugging
P.S. I'm still overwhelmed how good that works. Even elements-highlighting work
Depending on the structure of your lists there are some tidyverse
options that work nicely with unequal length lists:
l <- list(a = list(var.1 = 1, var.2 = 2, var.3 = 3)
, b = list(var.1 = 4, var.2 = 5)
, c = list(var.1 = 7, var.3 = 9)
, d = list(var.1 = 10, var.2 = 11, var.3 = NA))
df <- dplyr::bind_rows(l)
df <- purrr::map_df(l, dplyr::bind_rows)
df <- purrr::map_df(l, ~.x)
# all create the same data frame:
# A tibble: 4 x 3
var.1 var.2 var.3
<dbl> <dbl> <dbl>
1 1 2 3
2 4 5 NA
3 7 NA 9
4 10 11 NA
You can also mix vectors and data frames:
library(dplyr)
bind_rows(
list(a = 1, b = 2),
data_frame(a = 3:4, b = 5:6),
c(a = 7)
)
# A tibble: 4 x 2
a b
<dbl> <dbl>
1 1 2
2 3 5
3 4 6
4 7 NA
Unfortunately, for me, setting "Expires" did not always work. The cookie was unaffected.
This code did work for me:
HttpContext.Current.Session.Abandon();
HttpContext.Current.Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));
where "ASP.NET_SessionId"
is the name of the cookie. This does not really delete the cookie, but overrides it with a blank cookie, which was close enough for me.
Here is a simple code for javascript validation, and after it validates it will clean the input file.
<input type="file" id="image" accept="image/*" onChange="validate(this.value)"/>
function validate(file) {
var ext = file.split(".");
ext = ext[ext.length-1].toLowerCase();
var arrayExtensions = ["jpg" , "jpeg", "png", "bmp", "gif"];
if (arrayExtensions.lastIndexOf(ext) == -1) {
alert("Wrong extension type.");
$("#image").val("");
}
}
The element has both an attribute and a property named checked
. The property determines the current state.
The attribute is a string, and the property is a boolean. When the element is created from the HTML code, the attribute is set from the markup, and the property is set depending on the value of the attribute.
If there is no value for the attribute in the markup, the attribute becomes null
, but the property is always either true
or false
, so it becomes false
.
When you set the property, you should use a boolean value:
document.getElementById('myRadio').checked = true;
If you set the attribute, you use a string:
document.getElementById('myRadio').setAttribute('checked', 'checked');
Note that setting the attribute also changes the property, but setting the property doesn't change the attribute.
Note also that whatever value you set the attribute to, the property becomes true
. Even if you use an empty string or null
, setting the attribute means that it's checked. Use removeAttribute
to uncheck the element using the attribute:
document.getElementById('myRadio').removeAttribute('checked');
We can use the core java stuff alone to read the CVS file column by column. Here is the sample code I have wrote for my requirement. I believe that it will help for some one.
BufferedReader br = new BufferedReader(new FileReader(csvFile));
String line = EMPTY;
int lineNumber = 0;
int productURIIndex = -1;
int marketURIIndex = -1;
int ingredientURIIndex = -1;
int companyURIIndex = -1;
// read comma separated file line by line
while ((line = br.readLine()) != null) {
lineNumber++;
// use comma as line separator
String[] splitStr = line.split(COMMA);
int splittedStringLen = splitStr.length;
// get the product title and uri column index by reading csv header
// line
if (lineNumber == 1) {
for (int i = 0; i < splittedStringLen; i++) {
if (splitStr[i].equals(PRODUCTURI_TITLE)) {
productURIIndex = i;
System.out.println("product_uri index:" + productURIIndex);
}
if (splitStr[i].equals(MARKETURI_TITLE)) {
marketURIIndex = i;
System.out.println("marketURIIndex:" + marketURIIndex);
}
if (splitStr[i].equals(COMPANYURI_TITLE)) {
companyURIIndex = i;
System.out.println("companyURIIndex:" + companyURIIndex);
}
if (splitStr[i].equals(INGREDIENTURI_TITLE)) {
ingredientURIIndex = i;
System.out.println("ingredientURIIndex:" + ingredientURIIndex);
}
}
} else {
if (splitStr != null) {
String conditionString = EMPTY;
// avoiding arrayindexoutboundexception when the line
// contains only ,,,,,,,,,,,,,
for (String s : splitStr) {
conditionString = s;
}
if (!conditionString.equals(EMPTY)) {
if (productURIIndex != -1) {
productCVSUriList.add(splitStr[productURIIndex]);
}
if (companyURIIndex != -1) {
companyCVSUriList.add(splitStr[companyURIIndex]);
}
if (marketURIIndex != -1) {
marketCVSUriList.add(splitStr[marketURIIndex]);
}
if (ingredientURIIndex != -1) {
ingredientCVSUriList.add(splitStr[ingredientURIIndex]);
}
}
}
}
If you are using a LinearLayout
, use the gravity
attribute :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center">
<ImageView android:layout_width="wrap_content"
android:id="@+id/imageView1"
android:src="@drawable/icon"
android:layout_height="wrap_content"
android:scaleType="centerInside" />
</LinearLayout>
If you are using a RelativeLayout
, you can use android:layout_centerInParent
as follows :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/icon"
android:scaleType="centerInside"
android:layout_centerInParent="true" />
</RelativeLayout>
For the former, convention over configuration. Rails default when you reference another table with
belongs_to :something
is to look for something_id
.
references
, or belongs_to
is actually newer way of writing the former with few quirks.
Important is to remember that it will not create foreign keys for you. In order to do that, you need to set it up explicitly using either:
t.references :something, foreign_key: true
t.belongs_to :something_else, foreign_key: true
or (note the plural):
add_foreign_key :table_name, :somethings
add_foreign_key :table_name, :something_elses`
The flag Xmx
specifies the maximum memory allocation pool for a Java Virtual Machine (JVM), while Xms
specifies the initial memory allocation pool.
This means that your JVM will be started with Xms
amount of memory and will be able to use a maximum of Xmx
amount of memory. For example, starting a JVM like below will start it with 256Â MB of memory and will allow the process to use up to 2048Â MB of memory:
java -Xms256m -Xmx2048m
The memory flag can also be specified in different sizes, such as kilobytes, megabytes, and so on.
-Xmx1024k
-Xmx512m
-Xmx8g
The Xms
flag has no default value, and Xmx
typically has a default value of 256Â MB. A common use for these flags is when you encounter a java.lang.OutOfMemoryError
.
When using these settings, keep in mind that these settings are for the JVM's heap, and that the JVM can and will use more memory than just the size allocated to the heap. From Oracle's documentation:
Note that the JVM uses more memory than just the heap. For example Java methods, thread stacks and native handles are allocated in memory separate from the heap, as well as JVM internal data structures.
Simple:
var element = $("span[name='test']");
$(element[0].attributes).each(function() {
console.log(this.nodeName+':'+this.nodeValue);});
Let me copy/paste the documentation section which it I wrote about week or two ago, after having a problem similar to yours:
import requests
import logging
# these two lines enable debugging at httplib level (requests->urllib3->httplib)
# you will see the REQUEST, including HEADERS and DATA, and RESPONSE with HEADERS but without DATA.
# the only thing missing will be the response.body which is not logged.
import httplib
httplib.HTTPConnection.debuglevel = 1
logging.basicConfig() # you need to initialize logging, otherwise you will not see anything from requests
logging.getLogger().setLevel(logging.DEBUG)
requests_log = logging.getLogger("requests.packages.urllib3")
requests_log.setLevel(logging.DEBUG)
requests_log.propagate = True
requests.get('http://httpbin.org/headers')
The validate_required function seems to expect an HTML form control (e.g, text input field) as first argument, and check whether there is a value there at all. That is not what you want in this case.
Also, when you write ['password'].value
, you create a new array of length one, containing the string
'password'
, and then read the non-existing property "value"
from it, yielding the undefined value.
What you may want to try instead is:
if (password.value != cpassword.value) { cpassword.focus(); return false; }
(You also need to write the error message somehow, but I can't see from your code how that is done.).
It depends on the way your page behaves. If you want this to happens asynchronously, you have to use AJAX. Try out "jQuery post()" on Google to find some tuts.
In other case, if this will happen when a user submits a form, you can send the variable in an hidden field or append ?variableName=someValue"
to then end of the URL you are opening. :
http://www.somesite.com/send.php?variableName=someValue
or
http://www.somesite.com/send.php?variableName=someValue&anotherVariable=anotherValue
This way, from PHP you can access this value as:
$phpVariableName = $_POST["variableName"];
for forms using POST method or:
$phpVariableName = $_GET["variableName"];
for forms using GET method or the append to url method I've mentioned above (querystring).
If you want to fix it on the right, for example, use justify-content: flex-end
.
More: http://www.w3schools.com/cssref/css3_pr_justify-content.asp
As far as I can tell from the question, the amount of padding you want will vary according to the data you have. Accordingly, the only solution to this is to scan the data before printing, to figure out the widest datum, and so find a width value you can pass to printf using the asterix operator, e.g.
loop over data - get correct padding, put into width
printf( "%*d\n", width, datum );
The HttpContext.Current.User.Identity.Name returns null
This depends on whether the authentication mode is set to Forms or Windows in your web.config file.
For example, if I write the authentication like this:
<authentication mode="Forms"/>
Then because the authentication mode="Forms", I will get null for the username. But if I change the authentication mode to Windows like this:
<authentication mode="Windows"/>
I can run the application again and check for the username, and I will get the username successfully.
For more information, see System.Web.HttpContext.Current.User.Identity.Name Vs System.Environment.UserName in ASP.NET.
Being aware of the transaction (autocommit, explicit and implicit) handling for your database can save you from having to restore data from a backup.
Transactions control data manipulation statement(s) to ensure they are atomic. Being "atomic" means the transaction either occurs, or it does not. The only way to signal the completion of the transaction to database is by using either a COMMIT
or ROLLBACK
statement (per ANSI-92, which sadly did not include syntax for creating/beginning a transaction so it is vendor specific). COMMIT
applies the changes (if any) made within the transaction. ROLLBACK
disregards whatever actions took place within the transaction - highly desirable when an UPDATE/DELETE statement does something unintended.
Typically individual DML (Insert, Update, Delete) statements are performed in an autocommit transaction - they are committed as soon as the statement successfully completes. Which means there's no opportunity to roll back the database to the state prior to the statement having been run in cases like yours. When something goes wrong, the only restoration option available is to reconstruct the data from a backup (providing one exists). In MySQL, autocommit is on by default for InnoDB - MyISAM doesn't support transactions. It can be disabled by using:
SET autocommit = 0
An explicit transaction is when statement(s) are wrapped within an explicitly defined transaction code block - for MySQL, that's START TRANSACTION
. It also requires an explicitly made COMMIT
or ROLLBACK
statement at the end of the transaction. Nested transactions is beyond the scope of this topic.
Implicit transactions are slightly different from explicit ones. Implicit transactions do not require explicity defining a transaction. However, like explicit transactions they require a COMMIT
or ROLLBACK
statement to be supplied.
Explicit transactions are the most ideal solution - they require a statement, COMMIT
or ROLLBACK
, to finalize the transaction, and what is happening is clearly stated for others to read should there be a need. Implicit transactions are OK if working with the database interactively, but COMMIT
statements should only be specified once results have been tested & thoroughly determined to be valid.
That means you should use:
SET autocommit = 0;
START TRANSACTION;
UPDATE ...;
...and only use COMMIT;
when the results are correct.
That said, UPDATE and DELETE statements typically only return the number of rows affected, not specific details. Convert such statements into SELECT statements & review the results to ensure correctness prior to attempting the UPDATE/DELETE statement.
DDL (Data Definition Language) statements are automatically committed - they do not require a COMMIT statement. IE: Table, index, stored procedure, database, and view creation or alteration statements.
For some one who is looking for scroll function just add the function and call when ever needed
scrollbarTop(){
window.scroll(0,0);
}
If you want to get the stdout AND know whether the command succeeded or not, just use returnStdout
and wrap it in an exception handler:
scripted pipeline
try {
// Fails with non-zero exit if dir1 does not exist
def dir1 = sh(script:'ls -la dir1', returnStdout:true).trim()
} catch (Exception ex) {
println("Unable to read dir1: ${ex}")
}
output:
[Pipeline] sh
[Test-Pipeline] Running shell script
+ ls -la dir1
ls: cannot access dir1: No such file or directory
[Pipeline] echo
unable to read dir1: hudson.AbortException: script returned exit code 2
Unfortunately hudson.AbortException is missing any useful method to obtain that exit status, so if the actual value is required you'd need to parse it out of the message (ugh!)
Contrary to the Javadoc https://javadoc.jenkins-ci.org/hudson/AbortException.html the build is not failed when this exception is caught. It fails when it's not caught!
Update: If you also want the STDERR output from the shell command, Jenkins unfortunately fails to properly support that common use-case. A 2017 ticket JENKINS-44930 is stuck in a state of opinionated ping-pong whilst making no progress towards a solution - please consider adding your upvote to it.
As to a solution now, there could be a couple of possible approaches:
a) Redirect STDERR to STDOUT 2>&1
- but it's then up to you to parse that out of the main output though, and you won't get the output if the command failed - because you're in the exception handler.
b) redirect STDERR to a temporary file (the name of which you prepare earlier) 2>filename
(but remember to clean up the file afterwards) - ie. main code becomes:
def stderrfile = 'stderr.out'
try {
def dir1 = sh(script:"ls -la dir1 2>${stderrfile}", returnStdout:true).trim()
} catch (Exception ex) {
def errmsg = readFile(stderrfile)
println("Unable to read dir1: ${ex} - ${errmsg}")
}
c) Go the other way, set returnStatus=true
instead, dispense with the exception handler and always capture output to a file, ie:
def outfile = 'stdout.out'
def status = sh(script:"ls -la dir1 >${outfile} 2>&1", returnStatus:true)
def output = readFile(outfile).trim()
if (status == 0) {
// output is directory listing from stdout
} else {
// output is error message from stderr
}
Caveat: the above code is Unix/Linux-specific - Windows requires completely different shell commands.
Well,
The container div is very good to have, because if You want the site centered, You just can't do it just with body or html... But You can, with divs. Why container? Its usually used, just because the code itselve has to be clean and readable. So that is container... It contains all website, in case You want to mess with it around :)
Good luck
Its not possible thats the whole point of hashing. You can however bruteforce by going through all possibilities (using all possible digits characters in every possible order) and hashing them and checking for a collision.
for more information on hashing and MD5 etc see: http://en.wikipedia.org/wiki/MD5 , http://en.wikipedia.org/wiki/Hash_function , http://en.wikipedia.org/wiki/Cryptographic_hash_function and http://onin.com/hhh/hhhexpl.html

If you use mongoose, you can just use(assuming you're using subdocuments and population):
Profile.findById profileId
.select 'friends'
.exec (err, profile) ->
if err or not profile
handleError err, profile, res
else
Status.find { profile: { $in: profile.friends } }, (err, statuses) ->
if err
handleErr err, statuses, res
else
res.json createJSON statuses
It retrieves Statuses
which belong to one of Profile
(profileId
) friends. Friends is array of references to other Profiles
. Profile
schema with friends
defined:
schema = new mongoose.Schema
# ...
friends: [
type: mongoose.Schema.Types.ObjectId
ref: 'Profile'
unique: true
index: true
]
For Xamarin Users:
If you extends all your activities to a BaseActivity
Just add:
this.RequestedOrientation = ScreenOrientation.Portrait;
This will resolve the problem. If you want any particular activity to be in landscape override this in OnActivityCreated
. As:
this.Activity.RequestedOrientation = ScreenOrientation.Landscape;
PLESK Nginx and GIT I was getting this error on plesk git and while pushing a large repo with (who knows what) it gave me this error with HTTP code 413 and i looked into following Server was Plesk and it had nginx running as well as apache2 so i looked into logs and found the error in nginx logs
Followed this link to allow plesk to rebuild configuration with larger file upload.
I skipped the php part for git
After that git push worked without any errors.
Too difficult :)

That's all, enjoy.
Yes, that is one way to get the first line of output from a command.
If the command outputs anything to standard error that you would like to capture in the same manner, you need to redirect the standard error of the command to the standard output stream:
utility 2>&1 | head -n 1
There are many other ways to capture the first line too, including sed 1q
(quit after first line), sed -n 1p
(only print first line, but read everything), awk 'FNR == 1'
(only print first line, but again, read everything) etc.
Microsoft Windows accepts any memory request from processes if it could be done.
There is no limit for the memory that can be provided to a process, except the Virtual Memory Size.
Virtual Memory Size is 4GB in 32bit systems for any processes, no matter how many applications you are running. Any processes can allocate up to 4GB memory in 32bit systems.
In practice, Windows automatically allocates some parts of allocated memory from RAM or page-file depending on processes requests and paging file mechanism.
But another limit is the size of paging file. If you have a small paging-file, you cannot allocated large memories. You could increase the size of paging file according to Microsoft to have more memory space.
Python 2.5 includes an uuid implementation which (in at least one version) needs the mac address. You can import the mac finding function into your own code easily:
from uuid import getnode as get_mac
mac = get_mac()
The return value is the mac address as 48 bit integer.
Named parameters are not supported by JPA in native queries, only for JPQL. You must use positional parameters.
Named parameters follow the rules for identifiers defined in Section 4.4.1. The use of named parameters applies to the Java Persistence query language, and is not defined for native queries. Only positional parameter binding may be portably used for native queries.
So, use this
Query q = em.createNativeQuery("SELECT count(*) FROM mytable where username = ?1");
q.setParameter(1, "test");
While JPA specification doesn't support named parameters in native queries, some JPA implementations (like Hibernate) may support it
Native SQL queries support positional as well as named parameters
However, this couples your application to specific JPA implementation, and thus makes it unportable.
Look at the filter
function.
If you just need a 1-pole low-pass filter, it's
xfilt = filter(a, [1 a-1], x);
where a = T/τ, T = the time between samples, and τ (tau) is the filter time constant.
Here's the corresponding high-pass filter:
xfilt = filter([1-a a-1],[1 a-1], x);
If you need to design a filter, and have a license for the Signal Processing Toolbox, there's a bunch of functions, look at fvtool and fdatool.
Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.
As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:
var clone = _.clone(data, true);
data[1].values.d = 'x';
_.isEqual(data, clone) === false
_.isEqual(data, clone) === true
I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.
Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).
You can use Environment Replacement in your Dockerfile
as follows:
ENV PATH="/opt/gtk/bin:${PATH}"
I am assuming you have site key and secret in place. Follow this step.
In your HTML file, add the script.
<script src="https://www.google.com/recaptcha/api.js?render=put your site key here"></script>
Also, do use jQuery for easy event handling.
Here is the simple form.
<form id="comment_form" action="form.php" method="post" >
<input type="email" name="email" placeholder="Type your email" size="40"><br><br>
<textarea name="comment" rows="8" cols="39"></textarea><br><br>
<input type="submit" name="submit" value="Post comment"><br><br>
</form>
You need to initialize the Google recaptcha and listen for the ready event. Here is how to do that.
<script>
// when form is submit
$('#comment_form').submit(function() {
// we stoped it
event.preventDefault();
var email = $('#email').val();
var comment = $("#comment").val();
// needs for recaptacha ready
grecaptcha.ready(function() {
// do request for recaptcha token
// response is promise with passed token
grecaptcha.execute('put your site key here', {action: 'create_comment'}).then(function(token) {
// add token to form
$('#comment_form').prepend('<input type="hidden" name="g-recaptcha-response" value="' + token + '">');
$.post("form.php",{email: email, comment: comment, token: token}, function(result) {
console.log(result);
if(result.success) {
alert('Thanks for posting comment.')
} else {
alert('You are spammer ! Get the @$%K out.')
}
});
});
});
});
</script>
Here is the sample PHP file. You can use Servlet or Node or any backend language in place of it.
<?php
$email;$comment;$captcha;
if(isset($_POST['email'])){
$email=$_POST['email'];
}if(isset($_POST['comment'])){
$comment=$_POST['comment'];
}if(isset($_POST['token'])){
$captcha=$_POST['token'];
}
if(!$captcha){
echo '<h2>Please check the the captcha form.</h2>';
exit;
}
$secretKey = "put your secret key here";
$ip = $_SERVER['REMOTE_ADDR'];
// post request to server
$url = 'https://www.google.com/recaptcha/api/siteverify?secret=' . urlencode($secretKey) . '&response=' . urlencode($captcha);
$response = file_get_contents($url);
$responseKeys = json_decode($response,true);
header('Content-type: application/json');
if($responseKeys["success"]) {
echo json_encode(array('success' => 'true'));
} else {
echo json_encode(array('success' => 'false'));
}
?>
Here is the tutorial link: https://codeforgeek.com/2019/02/google-recaptcha-v3-tutorial/
Hope it helps.
Only, if they accept different parameters. If there are no parameters, then you must have different names.
int doSomething(String s);
String doSomething(int); // this is fine
int doSomething(String s);
String doSomething(String s); // this is not
if you want to pass variable as param lets try this
if requirement is function and var as parmas then try this
setTimeout((param1,param2) => {
alert(param1 + param2);
postinsql(topicId);
},2000,'msg1', 'msg2')
if requirement is only variables as a params then try this
setTimeout((param1,param2) => { alert(param1 + param2) },2000,'msg1', 'msg2')
_x000D_
You can try this with ES5 and ES6
If you want everything in your post to be as $Variables you can use something like this:
foreach($_POST as $key => $value) {
eval("$" . $key . " = " . $value");
}

If you don't know where catalina.sh
is (or it never gets called), you can usually find it via ps
:
$ ps aux | grep catalina
chris 930 0.0 3.1 2987336 258328 s000 S Wed01PM 2:29.43 /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Dnop -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.library.path=/usr/local/apache-tomcat-7.0.29/lib -Djava.endorsed.dirs=/usr/local/apache-tomcat-7.0.29/endorsed -classpath /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar -Dcatalina.base=/Users/chris/blah/blah -Dcatalina.home=/usr/local/apache-tomcat-7.0.29 -Djava.io.tmpdir=/Users/chris/blah/blah/temp org.apache.catalina.startup.Bootstrap start
From the ps
output, you can see both catalina.home
and catalina.base
. catalina.home
is where the Tomcat base files are installed, and catalina.base
is where the running configuration of Tomcat exists. These are often set to the same value unless you have configured your Tomcat for multiple (configuration) instances to be launched from a single Tomcat base install.
You can also interrogate the JVM directly if you can't find it in a ps
listing:
$ jinfo -sysprops 930 | grep catalina
Attaching to process ID 930, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 20.8-b03-424
catalina.base = /Users/chris/blah/blah
[...]
catalina.home = /usr/local/apache-tomcat-7.0.29
If you can't manage that, you can always try to write a JSP that dumps the values of the two system properties catalina.home
and catalina.base
.
There is a pretty nice infinite scroll plugin here
I've never programmed one myself, but I would imagine this is how it works.
An event is bound to the the window scrolling
$(window).scroll(myInfinteScrollFunction);
The called function checks if scroll top is greater than the window size
function myInfiniteScrollFunction() {
if($(window).scrollTop() == $(window).height())
makeAjaxRequest();
}
An AJAX request is made, specifying which result # to start at, how many to grab, and any other parameters necessary for the data pull.
$.ajax({
type: "POST",
url: "myAjaxFile.php",
data: {"resultNum": 30, "numPerPage": 50, "query": "interesting%20icons" },
success: myInfiniteLoadFunction(msg)
});
The ajax returns some (most-likely JSON formatted) content, and passes them into the loadnig function.
Hope that makes sense.
Here is some SQL that actually make sense:
SELECT m.id FROM match m LEFT JOIN email e ON e.id = m.id WHERE e.id IS NULL
Simple is always better.
I tried restarting Xcode (7) and nothing (the have you tried switching it off and on again of iOS development for me :-)). I then tried by restarting my box and that worked.
In my case the script was failing when copying a file from a location to another one. I think it could have been related to Finder screwing with writing rights over certain folders.
On SmtpClient there is an EnableSsl property that you would set.
i.e.
SmtpClient client = new SmtpClient(exchangeServer);
client.EnableSsl = true;
client.Send(msg);
I was looking a lot to find a solution for sticy menue with old school JS (without JQuery). So I build small test to play with it. I think it can be helpfull to those looking for solution in js. It needs improvments of unsticking the menue back, and making it more smooth. Also I find a nice solution with JQuery that clones the original div instead of position fixed, its better since the rest of page element dont need to be replaced after fixing. Anyone know how to that with JS ? Please remark, correct and improve.

From git reset
"pull" or "merge" always leaves the original tip of the current branch in
ORIG_HEAD
.git reset --hard ORIG_HEAD
Resetting hard to it brings your index file and the working tree back to that state, and resets the tip of the branch to that commit.
git reset --merge ORIG_HEAD
After inspecting the result of the merge, you may find that the change in the other branch is unsatisfactory. Running "
git reset --hard ORIG_HEAD
" will let you go back to where you were, but it will discard your local changes, which you do not want. "git reset --merge
" keeps your local changes.
Before any patches are applied, ORIG_HEAD is set to the tip of the current branch.
This is useful if you have problems with multiple commits, like running 'git am
' on the wrong branch or an error in the commits that is more easily fixed by changing the mailbox (e.g. +errors in the "From:" lines).In addition, merge always sets '
.git/ORIG_HEAD
' to the original state of HEAD so a problematic merge can be removed by using 'git reset ORIG_HEAD
'.
Note: from here
HEAD is a moving pointer. Sometimes it means the current branch, sometimes it doesn't.
So HEAD is NOT a synonym for "current branch" everywhere already.
HEAD means "current" everywhere in git, but it does not necessarily mean "current branch" (i.e. detached HEAD).
But it almost always means the "current commit".
It is the commit "git commit
" builds on top of, and "git diff --cached
" and "git status
" compare against.
It means the current branch only in very limited contexts (exactly when we want a branch name to operate on --- resetting and growing the branch tip via commit/rebase/etc.).Reflog is a vehicle to go back in time and time machines have interesting interaction with the notion of "current".
HEAD@{5.minutes.ago}
could mean "dereference HEAD symref to find out what branch we are on RIGHT NOW, and then find out where the tip of that branch was 5 minutes ago".
Alternatively it could mean "what is the commit I would have referred to as HEAD 5 minutes ago, e.g. if I did "git show HEAD" back then".
git1.8.4 (July 2013) introduces introduced a new notation!
(Actually, it will be for 1.8.5, Q4 2013: reintroduced with commit 9ba89f4), by Felipe Contreras.
Instead of typing four capital letters "
HEAD
", you can say "@
" now,
e.g. "git log @
".
See commit cdfd948
Typing '
HEAD
' is tedious, especially when we can use '@
' instead.The reason for choosing '
@
' is that it follows naturally from theref@op
syntax (e.g.HEAD@{u}
), except we have no ref, and no operation, and when we don't have those, it makes sens to assume 'HEAD
'.So now we can use '
git show @~1
', and all that goody goodness.Until now '
@
' was a valid name, but it conflicts with this idea, so let's make it invalid. Probably very few people, if any, used this name.
When you say:
#include <cstring>
the g++ compiler should put the <string.h>
declarations it itself includes into the std::
AND the global namespaces. It looks for some reason as if it is not doing that. Try replacing one instance of strcpy
with std::strcpy
and see if that fixes the problem.
I solved myself this and I put the answer in scope to help other user that have same problem: We have an event in bootstrap and we can use that event to set overflow: inherit
but this will work if you don't have the css property on your parent container.
$('.table-responsive').on('show.bs.dropdown', function () {
$('.table-responsive').css( "overflow", "inherit" );
});
$('.table-responsive').on('hide.bs.dropdown', function () {
$('.table-responsive').css( "overflow", "auto" );
})
info:
In this fiddle example works strange and I'm not sure why but in my project works just fine.
Yes, it absolutely is - assuming you've got the appropriate security permissions. Use Field.setAccessible(true)
first if you're accessing it from a different class.
import java.lang.reflect.*;
class Other
{
private String str;
public void setStr(String value)
{
str = value;
}
}
class Test
{
public static void main(String[] args)
// Just for the ease of a throwaway test. Don't
// do this normally!
throws Exception
{
Other t = new Other();
t.setStr("hi");
Field field = Other.class.getDeclaredField("str");
field.setAccessible(true);
Object value = field.get(t);
System.out.println(value);
}
}
And no, you shouldn't normally do this... it's subverting the intentions of the original author of the class. For example, there may well be validation applied in any situation where the field can normally be set, or other fields may be changed at the same time. You're effectively violating the intended level of encapsulation.
In my case, I also needed to reset the cached config files:
php artisan key:generate
php artisan config:cache
OK, renaming a branch both locally and on the remote is pretty easy!...
If you on the branch, you can easily do:
git branch -m <branch>
or if not, you need to do:
git branch -m <your_old_branch> <your_new_branch>
Then, push deletion to the remote like this:
git push origin <your_old_branch>
Now you done, if you get upstream error while you trying to push, simply do:
git push --set-upstream origin <your_new_branch>
I also create the image below to show the steps in real command line, just follow the steps and you would be good:
If you are using mongoose, I have found the following plugin to be a useful implementation of the JSON Patch format
The CSS for styling lists is here, but is basically:
li {
list-style-type: decimal;
list-style-position: inside;
}
However, the specific layout you're after can probably only be achieved by delving into the innards of the layout with something like this (note that I haven't actually tried it):
ol { counter-reset: item }
li { display: block }
li:before { content: counter(item) ") "; counter-increment: item }
To quote the documentation:
Key words and unquoted identifiers are case insensitive. Therefore:
UPDATE MY_TABLE SET A = 5;
can equivalently be written as:
uPDaTE my_TabLE SeT a = 5;
You could also write it using quoted identifiers:
UPDATE "my_table" SET "a" = 5;
Quoting an identifier makes it case-sensitive, whereas unquoted names are always folded to lower case (unlike the SQL standard where unquoted names are folded to upper case). For example, the identifiers FOO
, foo
, and "foo"
are considered the same by PostgreSQL, but "Foo"
and "FOO"
are different from these three and each other.
If you want to write portable applications you are advised to always quote a particular name or never quote it.
C++ has Automatic variables - not Stack variables.
Automatic variable means that C++ compiler handles memory allocation / free by itself. C++ can automatically handle objects of any class - no matter whether it has dynamically allocated members or not. It's achieved by strong guarantee of C++ that object's destructor will be called automatically when execution is going out of scope where automatic variable was declared. Inside of a C++ object can be a lot of dynamic allocations with new
in constructor, and when such an object is declared as an automatic variable - all dynamic allocations will be performed, and freed then in destructor.
Stack variables in C can't be dynamically allocated. Stack in C can store pointers, or fixed arrays or structs - all of fixed size, and these things are being allocated in memory in linear order. When a C program frees a stack variable - it just moves stack pointer back and nothing more.
Even though C++ programs can use Stack memory segment for storing primitive types, function's args, or other, - it's all decided by C++ compiler, not by program developer. Thus, it is conceptually wrong to equal C++ automatic variables and C stack variables.
Use an absolutely positioned pseudo element:
ul:after {
content: '';
width: 0;
height: 100%;
position: absolute;
border: 1px solid black;
top: 0;
left: 100px;
}
The sender is the control that the action is for (say OnClick, it's the button).
The EventArgs are arguments that the implementor of this event may find useful. With OnClick it contains nothing good, but in some events, like say in a GridView 'SelectedIndexChanged', it will contain the new index, or some other useful data.
What Chris is saying is you can do this:
protected void someButton_Click (object sender, EventArgs ea)
{
Button someButton = sender as Button;
if(someButton != null)
{
someButton.Text = "I was clicked!";
}
}

fpath = fpath.replace("/","\\") # forwin
ftmp.close()

data = ""
with open(fpath, 'r') as file:
data = file.read()
file.close()
os.remove(fpath)
return data

I Know this is a old question, and Pawel has given the correct answer, I just wanted to show a code example of how to do some string processing, and avoid an extra class for the list of a primitive type.
public class Test
{
public Test()
{
_strings = new List<string>
{
"test",
"test2",
"test3",
"test4"
};
}
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
private List<String> _strings { get; set; }
public List<string> Strings
{
get { return _strings; }
set { _strings = value; }
}
[Required]
public string StringsAsString
{
get { return String.Join(',', _strings); }
set { _strings = value.Split(',').ToList(); }
}
}
In cpp, you need to pay special attention to string types when using execvp
:
#include <iostream>
#include <string>
#include <cstring>
#include <stdio.h>
#include <unistd.h>
using namespace std;
const size_t MAX_ARGC = 15; // 1 command + # of arguments
char* argv[MAX_ARGC + 1]; // Needs +1 because of the null terminator at the end
// c_str() converts string to const char*, strdup converts const char* to char*
argv[0] = strdup(command.c_str());
// start filling up the arguments after the first command
size_t arg_i = 1;
while (cin && arg_i < MAX_ARGC) {
string arg;
cin >> arg;
if (arg.empty()) {
argv[arg_i] = nullptr;
break;
} else {
argv[arg_i] = strdup(arg.c_str());
}
++arg_i;
}
// Run the command with arguments
if (execvp(command.c_str(), argv) == -1) {
// Print error if command not found
cerr << "command '" << command << "' not found\n";
}
Reference: execlp?execvp?????
I wanted this:
MapVC is a Map in full screen.
When I press a button, it opens PopupVC (not in full screen) above the map.
When I press a button in PopupVC, it returns to MapVC, and then I want to execute viewDidAppear.
I did this:
MapVC.m: in the button action, a segue programmatically, and set delegate
- (void) buttonMapAction{
PopupVC *popvc = [self.storyboard instantiateViewControllerWithIdentifier:@"popup"];
popvc.delegate = self;
[self presentViewController:popvc animated:YES completion:nil];
}
- (void)dismissAndPresentMap {
[self dismissViewControllerAnimated:NO completion:^{
NSLog(@"dismissAndPresentMap");
//When returns of the other view I call viewDidAppear but you can call to other functions
[self viewDidAppear:YES];
}];
}
PopupVC.h: before @interface, add the protocol
@protocol PopupVCProtocol <NSObject>
- (void)dismissAndPresentMap;
@end
after @interface, a new property
@property (nonatomic,weak) id <PopupVCProtocol> delegate;
PopupVC.m:
- (void) buttonPopupAction{
//jump to dismissAndPresentMap on Map view
[self.delegate dismissAndPresentMap];
}
There seems to be no problem since the int to bool cast is done implicitly. This works in Microsoft Visual C++, GCC and Intel C++ compiler. No problem in either C or C++.
I'm not sure how necessary this is, and it adds a call to getElementById
, but if you're really keen on getting inline JavaScript out of your code, you can pass it as an HTML attribute, namely:
<span class="metadata" id="metadata-size-of-widget" title="<?php echo json_encode($size_of_widget) ?>"></span>
And then in your JavaScript:
var size_of_widget = document.getElementById("metadata-size-of-widget").title;
If you're using node:
values.js
:export let someValues = {
value1: 0
}
Then just import it as needed at the top of each file it's used in (e.g., file.js
):
import { someValues } from './values'
console.log(someValues);
There's a few approaches for this:
No, LabelEncoder
does not do this. It takes 1-d arrays of class labels and produces 1-d arrays. It's designed to handle class labels in classification problems, not arbitrary data, and any attempt to force it into other uses will require code to transform the actual problem to the problem it solves (and the solution back to the original space).
The following approach works in Chrome, Firefox, Internet Explorer and Edge, and in recent versions of Safari (copy support was added in version 10 which was released Oct 2016).
Note: you will not see the textarea, as it is added and removed within the same synchronous invocation of Javascript code.
Some things to watch out for if you are implementing this yourself:
The function below should handle all of the following issues as cleanly as possible. Please leave a comment if you find any problems or have any suggestions for improving it.
// Copies a string to the clipboard. Must be called from within an
// event handler such as click. May return false if it failed, but
// this is not always possible. Browser support for Chrome 43+,
// Firefox 42+, Safari 10+, Edge and Internet Explorer 10+.
// Internet Explorer: The clipboard feature may be disabled by
// an administrator. By default a prompt is shown the first
// time the clipboard is used (per session).
function copyToClipboard(text) {
if (window.clipboardData && window.clipboardData.setData) {
// Internet Explorer-specific code path to prevent textarea being shown while dialog is visible.
return clipboardData.setData("Text", text);
}
else if (document.queryCommandSupported && document.queryCommandSupported("copy")) {
var textarea = document.createElement("textarea");
textarea.textContent = text;
textarea.style.position = "fixed"; // Prevent scrolling to bottom of page in Microsoft Edge.
document.body.appendChild(textarea);
textarea.select();
try {
return document.execCommand("copy"); // Security exception may be thrown by some browsers.
}
catch (ex) {
console.warn("Copy to clipboard failed.", ex);
return false;
}
finally {
document.body.removeChild(textarea);
}
}
}
cat ip_addresses | sort | uniq -c | sort -nr | awk '{print $2 " " $1}'

This is just the XML Name Space declaration. We use this Name Space in order to specify that the attributes listed below, belongs to Android. Thus they starts with "android:"
You can actually create your own custom attributes. So to prevent the name conflicts where 2 attributes are named the same thing, but behave differently, we add the prefix "android:" to signify that these are Android attributes.
Thus, this Name Space declaration must be included in the opening tag of the root view of your XML file.
Building on @tmullaney 's answer, you can also left join in the sys.objects view to get insight when explicit permissions have been granted on objects. Make sure to use the LEFT join:
SELECT DISTINCT pr.principal_id, pr.name AS [UserName], pr.type_desc AS [User_or_Role], pr.authentication_type_desc AS [Auth_Type], pe.state_desc,
pe.permission_name, pe.class_desc, o.[name] AS 'Object'
FROM sys.database_principals AS pr
JOIN sys.database_permissions AS pe ON pe.grantee_principal_id = pr.principal_id
LEFT JOIN sys.objects AS o on (o.object_id = pe.major_id)
It depends what is the character and what encoding it is in:
An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits.
An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte).
A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes).
A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits. This is the encoding used by Windows internally.
A Unicode character in UTF-32 encoding is always 32 bits (4 bytes).
An ASCII character in UTF-8 is 8 bits (1 byte), and in UTF-16 - 16 bits.
The additional (non-ASCII) characters in ISO-8895-1 (0xA0-0xFF) would take 16 bits in UTF-8 and UTF-16.
That would mean that there are between 0.03125 and 0.125 characters in a bit.
