Just add a new form and add buttons and a label. Give the value to be shown and the text of the button, etc. in its constructor, and call it from anywhere you want in the project.
In project -> Add Component -> Windows Form and select a form
Add some label and buttons.
Initialize the value in constructor and call it from anywhere.
public class form1:System.Windows.Forms.Form
{
public form1()
{
}
public form1(string message,string buttonText1,string buttonText2)
{
lblMessage.Text = message;
button1.Text = buttonText1;
button2.Text = buttonText2;
}
}
// Write code for button1 and button2 's click event in order to call
// from any where in your current project.
// Calling
Form1 frm = new Form1("message to show", "buttontext1", "buttontext2");
frm.ShowDialog();
If anyone wants AutoClosingMessageBox in c++ I have implemented the equivalent code here is the link to gists
static intptr_t MessageBoxHookProc(int nCode, intptr_t wParam, intptr_t lParam)
{
if (nCode < 0)
return CallNextHookEx(hHook, nCode, wParam, lParam);
auto msg = reinterpret_cast<CWPRETSTRUCT*>(lParam);
auto hook = hHook;
//Hook Messagebox on Initialization.
if (!hookCaption.empty() && msg->message == WM_INITDIALOG)
{
int nLength = GetWindowTextLength(msg->hwnd);
char* text = new char[captionLen + 1];
GetWindowText(msg->hwnd, text, captionLen + 1);
//If Caption window found Unhook it.
if (hookCaption == text)
{
hookCaption = string("");
SetTimer(msg->hwnd, (uintptr_t)timerID, hookTimeout, (TIMERPROC)hookTimer);
UnhookWindowsHookEx(hHook);
hHook = 0;
}
}
return CallNextHookEx(hook, nCode, wParam, lParam);
}
Your call to MessageBox.Show
needs to pass MessageBoxButtons.YesNo
to get the Yes/No buttons instead of the OK button.
Compare the result of that call (which will block execution until the dialog returns) to DialogResult.Yes
....
if (MessageBox.Show("Are you sure?", "Confirm", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
// user clicked yes
}
else
{
// user clicked no
}
The code compiles ok for me. May be you have forgotten to add the import:
import android.app.AlertDialog;
Anyway, you have a good tutorial here.
DialogResult result = MessageBox.Show("Do you want to save changes?", "Confirmation", MessageBoxButtons.YesNoCancel);
if(result == DialogResult.Yes)
{
//...
}
else if (result == DialogResult.No)
{
//...
}
else
{
//...
}
You could use Javascript:
// This is in the PHP file and sends a Javascript alert to the client
$message = "wrong answer";
echo "<script type='text/javascript'>alert('$message');</script>";
Try this
MsgBox("Are you sure want to Exit", MsgBoxStyle.YesNo, "")
If True Then
End
End If
I don't think a message box is the best way to go with this as you would need the VB code running in a loop to check the cell contents, or unless you plan to run the macro manually. In this case I think it would be better to add conditional formatting to the cell to change the background to red (for example) if the value exceeds the upper limit.
Try this:
System.Windows.Forms.MessageBox.Show("Here's a message!");

I added this to the Button of a datagrid to get the values of the cells in the row that the user is clicking:
string DGCell = dataGridView1.Rows[e.RowIndex].Cells[X].Value.ToString();
where X is the cell you want to check. Datagrid column count starts at 1 not 0 in my case. Not sure if it is default of a datagrid or because I am using SQL to populate the info.
I use a utility named msgbox.exe from here: http://www.paulsadowski.com/WSH/cmdprogs.htm
<script type="text/javascript">
window.alert("My name is George. Welcome!")
</script>
Right click the solution explorer and choose the add reference.one
dialog box will be appear. On that select (.net)-> System.windows.form
. Imports System.Windows.Forms (vb)
and using System.windows.forms(C#)
copy this in your coding and then write messagebox.show("")
.
If you want to have your own nice looking wpf MessageBox: Create new Wpf Windows
here is xaml :

for cs of this file :
public partial class MessageboxNew : Window
{
public MessageboxNew()
{
InitializeComponent();
//second time show error solved
if (Application.Current == null) new Application();
Application.Current.ShutdownMode = ShutdownMode.OnExplicitShutdown;
}
private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
DialogResult = true;
}
private void cancel_Click(object sender, RoutedEventArgs e)
{
DialogResult = false;
}
private void FrameworkElement_OnLoaded(object sender, RoutedEventArgs e)
{
this.MouseDown += delegate { DragMove(); };
}
}
then create a class to use this :
public class Mk_MessageBox
{
public static bool? Show(string title, string text)
{
MessageboxNew msg = new MessageboxNew
{
TitleBar = {Text = title},
Textbar = {Text = text}
};
msg.noBtn.Focus();
return msg.ShowDialog();
}
}
now you can create your message box like this:
var result = Mk_MessageBox.Show("Remove Alert", "This is gonna remove directory from host! Are you sure?");
if (result == true)
{
// whatever
}
copy this to App.xaml inside

Try this, it's simple enough to justify the time...
This is for Win32 API, written in C. Translate it as you need...
case WM_NOTIFY:{
HWND X=FindWindow("#32770",NULL);
if(GetParent(X)==H_frame){int Px,Py,Sx,Sy; RECT R1,R2;
GetWindowRect(hwnd,&R1); GetWindowRect(X,&R2);
Sx=R2.right-R2.left,Px=R1.left+(R1.right-R1.left)/2-Sx/2;
Sy=R2.bottom-R2.top,Py=R1.top+(R1.bottom-R1.top)/2-Sy/2;
MoveWindow(X,Px,Py,Sx,Sy,1);
}
} break;
Add that to the WndProc code... You can set position as you like, in this case it just centres over the main program window. It will do this for any messagebox, or file open/save dialog, and likely some other native controls. I'm not sure, but I think you may need to include COMMCTRL or COMMDLG to use this, at least, you will if you want open/save dialogs.
I experimented with looking at the notify codes and hwndFrom of NMHDR, then decided it was just as effective, and far easier, not to. If you really want to be very specific, tell FindWindow to look for a unique caption (title) you give to the window you want it to find.
This fires before the messagebox is drawn onscreen, so if you set a global flag to indicate when action is done by your code, and look for a unique caption, you be sure that actions you take will only occur once (there will likely be multiple notifiers). I haven't explored this in detail, but I managed get CreateWindow to put an edit box on a messagebox dialog. It looked as out of place as a rat's ear grafted onto the spine of a cloned pig, but it works. Doing things this way may be far easier than having to roll your own.
Crow.
EDIT: Small correction to make sure that the right window is handled. Make sure that parent handles agree throughout, and this should work ok. It does for me, even with two instances of the same program...
Why not use:
Dim msg as String = String.Format("Variable = {0}", variable)
More info on String.Format
Try this :
SELECT CONVERT(varchar(2), GETDATE(), 101)
You can use StringEscapeUtils from Apache Commons Logging utility or escape manually using code for each character.
Namenode enters into safemode when there is shortage of memory. As a result the HDFS becomes readable only. That means one can not create any additional directory or file in the HDFS. To come out of the safemode, the following command is used:
hadoop dfsadmin -safemode leave
If you are using cloudera manager:
go to >>Actions>>Leave Safemode
But it doesn't always solve the problem. The complete solution lies in making some space in the memory. Use the following command to check your memory usage.
free -m
If you are using cloudera, you can also check if the HDFS is showing some signs of bad health. It probably must be showing some memory issue related to the namenode. Allot more memory by following the options available. I am not sure what commands to use for the same if you are not using cloudera manager but there must be a way. Hope it helps! :)
We can do this by css3 too. Try this:
.halfsize {
-moz-transform:scale(0.5);
-webkit-transform:scale(0.5);
transform:scale(0.5);
}
<img class="halfsize" src="image4.jpg">
For others who need to do this with just stock .NET and PowerShell (no additional SQL tools installed) here is the function that I use:
function Invoke-SQL {
param(
[string] $dataSource = ".\SQLEXPRESS",
[string] $database = "MasterData",
[string] $sqlCommand = $(throw "Please specify a query.")
)
$connectionString = "Data Source=$dataSource; " +
"Integrated Security=SSPI; " +
"Initial Catalog=$database"
$connection = new-object system.data.SqlClient.SQLConnection($connectionString)
$command = new-object system.data.sqlclient.sqlcommand($sqlCommand,$connection)
$connection.Open()
$adapter = New-Object System.Data.sqlclient.sqlDataAdapter $command
$dataset = New-Object System.Data.DataSet
$adapter.Fill($dataSet) | Out-Null
$connection.Close()
$dataSet.Tables
}
I have been using this so long I don't know who wrote which parts. This was distilled from others' examples, but simplified to be clear and just what is needed without extra dependencies or features.
I use and share this often enough that I have turned this into a script module on GitHub so that you can now go to your modules directory and execute git clone https://github.com/ChrisMagnuson/InvokeSQL
and from that point forward invoke-sql will automatically be loaded when you go to use it (assuming your using PowerShell v3 or later).
require_relative
is a convenient subset of require
require_relative('path')
equals:
require(File.expand_path('path', File.dirname(__FILE__)))
if __FILE__
is defined, or it raises LoadError
otherwise.
This implies that:
require_relative 'a'
and require_relative './a'
require relative to the current file (__FILE__
).
This is what you want to use when requiring inside your library, since you don't want the result to depend on the current directory of the caller.
eval('require_relative("a.rb")')
raises LoadError
because __FILE__
is not defined inside eval
.
This is why you can't use require_relative
in RSpec tests, which get eval
ed.
The following operations are only possible with require
:
require './a.rb'
requires relative to the current directory
require 'a.rb'
uses the search path ($LOAD_PATH
) to require. It does not find files relative to current directory or path.
This is not possible with require_relative
because the docs say that path search only happens when "the filename does not resolve to an absolute path" (i.e. starts with /
or ./
or ../
), which is always the case for File.expand_path
.
The following operation is possible with both, but you will want to use require
as it is shorter and more efficient:
require '/a.rb'
and require_relative '/a.rb'
both require the absolute path.Reading the source
When the docs are not clear, I recommend that you take a look at the sources (toggle source in the docs). In some cases, it helps to understand what is going on.
require:
VALUE rb_f_require(VALUE obj, VALUE fname) {
return rb_require_safe(fname, rb_safe_level());
}
require_relative:
VALUE rb_f_require_relative(VALUE obj, VALUE fname) {
VALUE base = rb_current_realfilepath();
if (NIL_P(base)) {
rb_loaderror("cannot infer basepath");
}
base = rb_file_dirname(base);
return rb_require_safe(rb_file_absolute_path(fname, base), rb_safe_level());
}
This allows us to conclude that
require_relative('path')
is the same as:
require(File.expand_path('path', File.dirname(__FILE__)))
because:
rb_file_absolute_path =~ File.expand_path
rb_file_dirname1 =~ File.dirname
rb_current_realfilepath =~ __FILE__
Nobody mentions memcmp
? This is also a good choice.
/* memcmp example */
#include <stdio.h>
#include <string.h>
int main ()
{
char buffer1[] = "DWgaOtP12df0";
char buffer2[] = "DWGAOTP12DF0";
int n;
n=memcmp ( buffer1, buffer2, sizeof(buffer1) );
if (n>0) printf ("'%s' is greater than '%s'.\n",buffer1,buffer2);
else if (n<0) printf ("'%s' is less than '%s'.\n",buffer1,buffer2);
else printf ("'%s' is the same as '%s'.\n",buffer1,buffer2);
return 0;
}
If you can assume that artist IDs increment over time, then the MIN(artist_id)
will be the earliest.
So try something like this (untested...)
SELECT *
FROM feeds f
LEFT JOIN artists a ON a.artist_id = (
SELECT
MIN(fa.artist_id) a_id
FROM feeds_artists fa
WHERE fa.feed_id = f.feed_id
) a
moment(moment('2015/04/09 16:00:00').add(7, 'd').format('YYYY/MM/DD HH:mm:mm'))
has to format and then convert to moment again.
Function
Public Function ArrayLen(arr As Variant) As Integer
ArrayLen = UBound(arr) - LBound(arr) + 1

Debug.Print ArrayLen(arr) ' Prints 3. Everything's going to be ok.
For a similar post a long time ago there seems to be issues with making table visibility hidden.
You have two options, one is to use the display:none
attribute.
Or two wrap the table in a div and make the div hidden.
<div id="wrapper" style="visibility:hidden">
<table>
<tr>
<td>
Content
</td>
</tr>
</table>
</div>
You can detect and specify variables for several operating systems like that:
if(WIN32)
# for Windows operating system in general
endif()
Or:
if(MSVC OR MSYS OR MINGW)
# for detecting Windows compilers
endif()
if(APPLE)
# for MacOS X or iOS, watchOS, tvOS (since 3.10.3)
endif()
if(UNIX AND NOT APPLE)
# for Linux, BSD, Solaris, Minix
endif()
To solve your issue with the Windows-specific wsock32
library, just remove it from other systems, like that:
if(WIN32)
target_link_libraries(${PROJECT_NAME} bioutils wsock32)
else
target_link_libraries(${PROJECT_NAME} bioutils)
endif()
As mentioned, you simply want the standard R apply
function applied to columns (MARGIN=2
):
wifi[,4:9] <- apply(wifi[,4:9], MARGIN=2, FUN=A)
Or, for short:
wifi[,4:9] <- apply(wifi[,4:9], 2, A)
This updates columns 4:9 in-place using the A()
function. Now, let's assume that na.rm
is an argument to A()
, which it probably should be. We can pass na.rm=T
to remove NA values from the computation like so:
wifi[,4:9] <- apply(wifi[,4:9], MARGIN=2, FUN=A, na.rm=T)
The same is true for any other arguments you want to pass to your custom function.
You can get clean and clear solutions by building the appropriate predicates as helper functions. In other words, use the Python set-builder notation the same way you would write the answer with regular mathematics set-notation.
The whole idea behind set comprehensions is to let us write and reason in code the same way we do mathematics by hand.
With an appropriate predicate in hand, problem 1 simplifies to:
low_primes = {x for x in range(1, 100) if is_prime(x)}
And problem 2 simplifies to:
low_prime_pairs = {(x, x+2) for x in range(1,100,2) if is_prime(x) and is_prime(x+2)}
Note how this code is a direct translation of the problem specification, "A Prime Pair is a pair of consecutive odd numbers that are both prime."
P.S. I'm trying to give you the correct problem solving technique without actually giving away the answer to the homework problem.

See the Hibernate Forum for a explanation of the subtle differences between persist and save. It looks like the difference is the time the INSERT statement is ultimately executed. Since save does return the identifier, the INSERT statement has to be executed instantly regardless of the state of the transaction (which generally is a bad thing). Persist won't execute any statements outside of the currently running transaction just to assign the identifier. Save/Persist both work on transient instances, ie instances which have no identifier assigned yet and as such are not saved in the DB.
Update and Merge both work on detached instances, ie instances which have a corresponding entry in the DB but which are currently not attached to (or managed by) a Session. The difference between them are what happens to the instance which is passed to the function. update tries to reattach the instance, that means that there must be no other instance of the persistent entity attached to the Session right now, otherwise an exception is thrown. merge, however, just copies all values to a persistent instance in the Session (which will be loaded if it is not currently loaded). The input object is not changed. So merge is more general than update, but may use more resources.

Just use replace()

It is good practice when you start creating website to reset all the margins and paddings. So I recommend on start just to simple do:
* { margin: 0, padding: 0 }
This will make margins and paddings of all elements to be 0, and then you can style them as you wish, because each browser has a different default margin and padding of the elements.
I had to merge some of those good answers here! This works for me:

exec sp_addlinkedserver @server = N'loopback', @srvproduct = N'', @provider = N'SQLOLEDB', @datasrc = @@servername
go

I did it in my project:

My issue was resolved by updating the metadata part of the connection string. Apparently it was pointing at the wrong .csdl / .ssdl / .msl reference.
PEP-8 recommends you indent lines to the opening parentheses if you put anything on the first line, so it should either be indenting to the opening bracket:
urlpatterns = patterns('',
url(r'^$', listing, name='investment-listing'))
or not putting any arguments on the starting line, then indenting to a uniform level:
urlpatterns = patterns(
'',
url(r'^$', listing, name='investment-listing'),
)
urlpatterns = patterns(
'', url(r'^$', listing, name='investment-listing'))
I suggest taking a read through PEP-8 - you can skim through a lot of it, and it's pretty easy to understand, unlike some of the more technical PEPs.

Following the functional approach a union
of two Array
s is just the composition of concat
and filter
. In order to provide optimal performance we resort to the native Set
data type, which is optimized for property lookups.
Anyway, the key question in conjunction with a union
function is how to treat duplicates. The following permutations are possible:
Array A + Array B
[unique] + [unique]
[duplicated] + [unique]
[unique] + [duplicated]
[duplicated] + [duplicated]
The first two permutations are easy to handle with a single function. However, the last two are more complicated, since you can't process them as long as you rely on Set
lookups. Since switching to plain old Object
property lookups would entail a serious performance hit the following implementation just ignores the third and fourth permutation. You would have to build a separate version of union
to support them.

From here on it gets trivial to implement an unionn
function, which accepts any number of arrays (inspired by naomik's comments):
// small, reusable auxiliary functions_x000D_
_x000D_
const uncurry = f => (a, b) => f(a) (b);_x000D_
const foldl = f => acc => xs => xs.reduce(uncurry(f), acc);_x000D_
_x000D_
const apply = f => a => f(a);_x000D_
const flip = f => b => a => f(a) (b);_x000D_
const concat = xs => y => xs.concat(y);_x000D_
const createSet = xs => new Set(xs);_x000D_
const filter = f => xs => xs.filter(apply(f));_x000D_
_x000D_
_x000D_
// union and unionn_x000D_
_x000D_
const union = xs => ys => {_x000D_
const zs = createSet(xs); _x000D_
return concat(xs) (_x000D_
filter(x => zs.has(x)_x000D_
? false_x000D_
: zs.add(x)_x000D_
) (ys));_x000D_
}_x000D_
_x000D_
const unionn = (head, ...tail) => foldl(union) (head) (tail);_x000D_
_x000D_
_x000D_
// mock data_x000D_
_x000D_
const xs = [1,2,2,3,4,5];_x000D_
const ys = [0,1,2,3,3,4,5,6,6];_x000D_
const zs = [0,1,2,3,4,5,6,7,8,9];_x000D_
_x000D_
_x000D_
// here we go_x000D_
_x000D_
console.log( unionn(xs, ys, zs) );
_x000D_
It turns out unionn
is just foldl
(aka Array.prototype.reduce
), which takes union
as its reducer. Note: Since the implementation doesn't use an additional accumulator, it will throw an error when you apply it without arguments.
All you need is convert string
to int
with +
and convert the result to boolean with !!
:
var response = {"isChecked":"1"};
response.isChecked = !!+response.isChecked
You can do this manipulation in the parse
method:
parse: function (response) {
response.isChecked = !!+response.isChecked;
return response;
}
UPDATE: 7 years later, I find Number(string)
conversion more elegant. Also mutating an object is not the best idea. That being said:
parse: function (response) {
return Object.assign({}, response, {
isChecked: !!Number(response.isChecked), // OR
isChecked: Boolean(Number(response.isChecked))
});
}

getClass() has the restriction that objects are only equal to other objects of the same class, the same run time type, as illustrated in the output of below code:
class ParentClass{
}
public class SubClass extends ParentClass{
public static void main(String []args){
ParentClass parentClassInstance = new ParentClass();
SubClass subClassInstance = new SubClass();
if(subClassInstance instanceof ParentClass){
System.out.println("SubClass extends ParentClass. subClassInstance is instanceof ParentClass");
}
if(subClassInstance.getClass() != parentClassInstance.getClass()){
System.out.println("Different getClass() return results with subClassInstance and parentClassInstance ");
}
}
}
Outputs:
SubClass extends ParentClass. subClassInstance is instanceof ParentClass.
Different getClass() return results with subClassInstance and parentClassInstance.
you can print it as string:
printf("%s\n", foo);

The problem in my case was that in order to catch another exception I had enabled common language runtime (CLR) exceptions. And I forgot to disable it.
I disabled it in my exception setting. and it overlooked this exception and went on to run and create a db for me (in my case) automatically.
i.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);
Note Your homeactivity launchmode should be single_task
df = data.frame(cond=c(rep("x",3),rep("y",3)),rating=c(x,y))
In C++, unlike (say) Java, an instance of a nested class doesn't intrinsically belong to any instance of the enclosing class. So bar::getA
doesn't have any specific instance of foo
whose a
it can be returning. I'm guessing that what you want is something like:
class bar {
private:
foo * const owner;
public:
bar(foo & owner) : owner(&owner) { }
int getA() {return owner->a;}
};
But even for this you may have to make some changes, because in versions of C++ before C++11, unlike (again, say) Java, a nested class has no special access to its enclosing class, so it can't see the protected
member a
. This will depend on your compiler version. (Hat-tip to Ken Wayne VanderLinde for pointing out that C++11 has changed this.)
I like to make it more dynamic
Class<?> serviceMonitor = MyService.class;
private void startMyService() { context.startService(new Intent(context, serviceMonitor)); }
private void stopMyService() { context.stopService(new Intent(context, serviceMonitor)); }
do not forget the Manifest
<service android:enabled="true" android:name=".MyService.class" />
A new solution if you use Android Studio 3.2, I solved this issue by added mavenCentral() to build.gradle of the project:
buildscript {
ext.kotlin_version = '1.3.0'
repositories {
mavenCentral()
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
}
allprojects {
repositories {
mavenCentral()
google()
jcenter()
}
}

A cleaner alternative would be to use a Dictionary
to handle parameters. They are key-value pairs after all.
private static readonly HttpClient httpclient;
static MyClassName()
{
// HttpClient is intended to be instantiated once and re-used throughout the life of an application.
// Instantiating an HttpClient class for every request will exhaust the number of sockets available under heavy loads.
// This will result in SocketException errors.
// https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=netframework-4.7.1
httpclient = new HttpClient();
}
var url = "http://myserver/method";
var parameters = new Dictionary<string, string> { { "param1", "1" }, { "param2", "2" } };
var encodedContent = new FormUrlEncodedContent (parameters);
var response = await httpclient.PostAsync (url, encodedContent).ConfigureAwait (false);
if (response.StatusCode == HttpStatusCode.OK) {
// Do something with response. Example get content:
// var responseContent = await response.Content.ReadAsStringAsync ().ConfigureAwait (false);
}
Also dont forget to Dispose()
httpclient, if you dont use the keyword using
As stated in the Remarks section of the HttpClient class in the Microsoft docs, HttpClient should be instantiated once and re-used.
Edit:
You may want to look into response.EnsureSuccessStatusCode();
instead of if (response.StatusCode == HttpStatusCode.OK)
.
You may want to keep your httpclient and dont Dispose()
it. See: Do HttpClient and HttpClientHandler have to be disposed?
Edit:
Do not worry about using .ConfigureAwait(false) in .NET Core. For more details look at https://blog.stephencleary.com/2017/03/aspnetcore-synchronization-context.html
Here's the GNU version of printf
... you can see it passing in stdout
to vfprintf
:
__printf (const char *format, ...)
{
va_list arg;
int done;
va_start (arg, format);
done = vfprintf (stdout, format, arg);
va_end (arg);
return done;
}
Here's a link to vfprintf
... all the formatting 'magic' happens here.
The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf
equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)
Something obvious, yet quite useful for someone new to NHibernate.
All XML Mapping files should be treated as Embedded Resources rather than the default Content. This option is set by editing the Build Action attribute in the file's properties.
XML files are then embedded into the assembly, and parsed at project startup during NHibernate's configuration phase.
A simple return
statement will 'stop' or return the function; in precise terms, it 'returns' function execution to the point at which the function was called - the function is terminated without further action.
That means you could have a number of places throughout your function where it might return. Like this:
def player():
# do something here
check_winner_variable = check_winner() # check something
if check_winner_variable == '1':
return
second_test_variable = second_test()
if second_test_variable == '1':
return
# let the computer do something
computer()

Same for pageX

pageX/Y
coordinates are relative to the top left corner of the whole rendered page (including parts hidden by scrolling),

I found that when you use a compound object as @Body
params, it could not work well with the Retrofit's GSONConverter
(under the assumption you are using that).
You have to use JsonObject
and not JSONObject
when working with that, it adds NameValueParams
without being verbose about it - you can only see that if you add another dependency of logging interceptor, and other shenanigans.
So what I found the best approach to tackle this is using RequestBody
.
You turn your object to RequestBody
with a simple api call and launch it.
In my case I'm converting a map:
val map = HashMap<String, Any>()
map["orderType"] = orderType
map["optionType"] = optionType
map["baseAmount"] = baseAmount.toString()
map["openSpotRate"] = openSpotRate.toString()
map["premiumAmount"] = premiumAmount.toString()
map["premiumAmountAbc"] = premiumAmountAbc.toString()
map["conversionSpotRate"] = (premiumAmountAbc / premiumAmount).toString()
return RequestBody.create(MediaType.parse("application/json; charset=utf-8"), JSONObject(map).toString())
and this is the call:
@POST("openUsvDeal")
fun openUsvDeal(
@Body params: RequestBody,
@Query("timestamp") timeStamp: Long,
@Query("appid") appid: String = Constants.APP_ID,
): Call<JsonObject>
What I think you may want is an ArrayList<Integer>
instead of an array. This will allow you do to:
ArrayList<Integer> arr = new ArrayList<Integer>(20);
System.out.println(arr.size());
The output will be 0
.
Then, you can add things to the list, and it will keep track of the count for you. (It will also grow the size of the backing storage as you need as well.)
Usual way to empty textbox using jquery is:
$('#txtInput').val('');
If above code is not working than please check that you are able to get the input element.

Make sure that the "Distributed Transaction Coordinator" Service is running on both database and client. Also make sure you check "Network DTC Access", "Allow Remote Client", "Allow Inbound/Outbound" and "Enable TIP".
To enable Network DTC Access for MS DTC transactions
Open the Component Services snap-in.
To open Component Services, click Start. In the search box, type dcomcnfg, and then press ENTER.
Expand the console tree to locate the DTC (for example, Local DTC) for which you want to enable Network MS DTC Access.
On the Action menu, click Properties.
Click the Security tab and make the following changes: In Security Settings, select the Network DTC Access check box.
In Transaction Manager Communication, select the Allow Inbound and Allow Outbound check boxes.
If I understand correctly, you're already using pandas.read_csv()
but would like to speed up the development process so that you don't have to load the file in every time you edit your script, is that right? I have a few recommendations:
you could load in only part of the CSV file using pandas.read_csv(..., nrows=1000)
to only load the top bit of the table, while you're doing the development
use ipython for an interactive session, such that you keep the pandas table in memory as you edit and reload your script.
convert the csv to an HDF5 table
updated use DataFrame.to_feather()
and pd.read_feather()
to store data in the R-compatible feather binary format that is super fast (in my hands, slightly faster than pandas.to_pickle()
on numeric data and much faster on string data).

In express.js (since version 3) you should use that syntax:
var fs = require('fs');
var http = require('http');
var https = require('https');
var privateKey = fs.readFileSync('sslcert/server.key', 'utf8');
var certificate = fs.readFileSync('sslcert/server.crt', 'utf8');
var credentials = {key: privateKey, cert: certificate};
var express = require('express');
var app = express();
// your express configuration here
var httpServer = http.createServer(app);
var httpsServer = https.createServer(credentials, app);
httpServer.listen(8080);
httpsServer.listen(8443);
In that way you provide express middleware to the native http/https server
If you want your app running on ports below 1024, you will need to use sudo
command (not recommended) or use a reverse proxy (e.g. nginx, haproxy).
Couldn't you just pass the a name attribute and wrap it in a form?
<form id="form" action="do_stuff.php" method="post">
<select id="select_catalog" name="select_catalog_query">
<?php <<<INSERT THE SELECT OPTION LOOP>>> ?>
</select>
</form>
And then look for $_POST['select_catalog_query']
?
A tool like systemtap (or a tracer) can monitor kernel signal-transmission logic and report. e.g., https://sourceware.org/systemtap/examples/process/sigmon.stp
# stap .../sigmon.stp -x 31994 SIGKILL
SPID SNAME RPID RNAME SIGNUM SIGNAME
5609 bash 31994 find 9 SIGKILL
The filtering if
block in that script can be adjusted to taste, or eliminated to trace systemwide signal traffic. Causes can be further isolated by collecting backtraces (add a print_backtrace()
and/or print_ubacktrace()
to the probe, for kernel- and userspace- respectively).
in my case, some characters like " , :"'{}[] " maybe corrupt the JSON format, so use try json.loads(str) except to check your input

According to the documentation NUM_ROWS is the "Number of rows in the table", so I can see how this might be confusing. There, however, is a major difference between these two methods.
This query selects the number of rows in MY_TABLE from a system view. This is data that Oracle has previously collected and stored.
select num_rows from all_tables where table_name = 'MY_TABLE'
This query counts the current number of rows in MY_TABLE
select count(*) from my_table
By definition they are difference pieces of data. There are two additional pieces of information you need about NUM_ROWS.
In the documentation there's an asterisk by the column name, which leads to this note:
Columns marked with an asterisk (*) are populated only if you collect statistics on the table with the ANALYZE statement or the DBMS_STATS package.
This means that unless you have gathered statistics on the table then this column will not have any data.
Statistics gathered in 11g+ with the default estimate_percent
, or with a 100% estimate, will return an accurate number for that point in time. But statistics gathered before 11g, or with a custom estimate_percent
less than 100%, uses dynamic sampling and may be incorrect. If you gather 99.999% a single row may be missed, which in turn means that the answer you get is incorrect.
If your table is never updated then it is certainly possible to use ALL_TABLES.NUM_ROWS to find out the number of rows in a table. However, and it's a big however, if any process inserts or deletes rows from your table it will be at best a good approximation and depending on whether your database gathers statistics automatically could be horribly wrong.
Generally speaking, it is always better to actually count the number of rows in the table rather then relying on the system tables.
Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.
Here's how to do it for Internet Explorer:
function copy (str)
{
//for IE ONLY!
window.clipboardData.setData('Text',str);
}
Try this jsfiddle. This is using jQuery and made from Hashem Qolami's answer. At first, make a regular table then make it scrollable.
const makeScrollableTable = function (tableSelector, tbodyHeight) {
let $table = $(tableSelector);
let $bodyCells = $table.find('tbody tr:first').children();
let $headCells = $table.find('thead tr:first').children();
let headColWidth = 0;
let bodyColWidth = 0;
headColWidth = $headCells.map(function () {
return $(this).outerWidth();
}).get();
bodyColWidth = $bodyCells.map(function () {
return $(this).outerWidth();
}).get();
$table.find('thead tr').children().each(function (i, v) {
$(v).css("width", headColWidth[i]+"px");
$(v).css("min-width", headColWidth[i]+"px");
$(v).css("max-width", headColWidth[i]+"px");
});
$table.find('tbody tr').children().each(function (i, v) {
$(v).css("width", bodyColWidth[i]+"px");
$(v).css("min-width", bodyColWidth[i]+"px");
$(v).css("max-width", bodyColWidth[i]+"px");
});
$table.find('thead').css("display", "block");
$table.find('tbody').css("display", "block");
$table.find('tbody').css("height", tbodyHeight+"px");
$table.find('tbody').css("overflow-y", "auto");
$table.find('tbody').css("overflow-x", "hidden");
};
Then you can use this function as follows:
makeScrollableTable('#test-table', 250);
import numpy as np
df['New_ID']=np.arange(880,880+len(df.Fruit))
df=df.reindex(columns=['New_ID','ID','Fruit'])
private static String readAll(Reader rd) throws IOException {
StringBuilder sb = new StringBuilder();
int cp;
while ((cp = rd.read()) != -1) {
sb.append((char) cp);
}
return sb.toString();
}
String jsonText = readAll(inputofyourjsonstream);
JSONObject json = new JSONObject(jsonText);
JSONArray arr = json.getJSONArray("sources");
Your arr would looks like: [ { "id":1001, "name":"jhon" }, { "id":1002, "name":"jhon" } ] You can use:
arr.getJSONObject(index)
to get the objects inside of the array.
Try this
SELECT CONVERT(varchar(11),getdate(),101) -- Converts to 'mm/dd/yyyy'
SELECT CONVERT(varchar(11),getdate(),103) -- Converts to 'dd/mm/yyyy'

in jQuery
you might target the Parent directly.
THIS IS USEFUL IF YOU DO NOT KNOW EXACTLY HOW MANY CHILDREN WILL BE ADDED DYNAMICALLY or IF YOU JUST CAN'T FIGURE OUT THEIR NUMBER.
var tWidth=0;
$('.children').each(function(i,e){
tWidth += $(e).width();
///Example: If the Children have a padding-left of 10px;..
//You could do instead:
tWidth += ($(e).width()+10);
})
$('#parent').css('width',tWidth);
This will let the parent
grow horizontally as the children
are beng added.
NOTE: This assumes that the '.children'
have a width
and Height
Set
Hope that Helps.
Running these commands solved my problem (credit to this answer):

You need to install a plugin, There is a free one from the eclipse foundation called the Web Tools Platform. It has all the development functionality that you'll need.
You can get the Java EE Edition of eclipse with has it pre-installed.
To create and run your first servlet:
doGet()
method.That should do it for you. You can use ant to build here if that's what you'd like but eclipse will actually do the build and automatically deploy the changes to the server. With Tomcat you might have to restart it every now and again depending on the change.
Lazy loading allows you to defer the association retrieval or to have a better control over the fetching strategy.
When you use EAGER loading, you define a global fetch plan which cannot be overridden at query time, meaning you are limited to a decision you took while designing your entity model. The EAGER fetching is a code smell, because the fetching strategy is a query-time policy and it might differ from a business use case to another.
The fetching strategy is a very important aspect, as too much EAGER fetching can cause serious performance related issues.
Answer based on @EdChum's comment on his answer. Comment is this -
groupby is notoriously slow and memory hungry, what you could do is sort by column A, then find the idxmin and idxmax (probably store this in a dict) and use this to slice your dataframe would be faster I think
Let's first create a dataframe with 500k categories in first column and total df shape 20 million as mentioned in question.
df = pd.DataFrame(columns=['a', 'b'])
df['a'] = (np.random.randint(low=0, high=500000, size=(20000000,))).astype(str)
df['b'] = list(range(20000000))
print(df.shape)
df.head()
# Sort data by first column
df.sort_values(by=['a'], ascending=True, inplace=True)
df.reset_index(drop=True, inplace=True)
# Create a temp column
df['temp_idx'] = list(range(df.shape[0]))
# Take all values of b in a separate list
all_values_b = list(df.b.values)
print(len(all_values_b))
# For each category in column a, find min and max indexes
gp_df = df.groupby(['a']).agg({'temp_idx': [np.min, np.max]})
gp_df.reset_index(inplace=True)
gp_df.columns = ['a', 'temp_idx_min', 'temp_idx_max']
# Now create final list_b column, using min and max indexes for each category of a and filtering list of b.
gp_df['list_b'] = gp_df[['temp_idx_min', 'temp_idx_max']].apply(lambda x: all_values_b[x[0]:x[1]+1], axis=1)
print(gp_df.shape)
gp_df.head()
This above code takes 2 minutes for 20 million rows and 500k categories in first column.
You can accomplish this with a slightly different syntax:
ng-class="{'approved': selectedForApproval.indexOf(jobSet) === -1}"
I solved this issue by creating a new virtual device and launching it from the AVD manager. The device takes a few minutes to start, you just have to wait. Then you can run your application on the already started device.
The only way I could get the .png
file I'm working with in as uint8
was with OpenCv.
cv2.imread(file)
actually returned numpy.ndarray
with dtype=uint8
Before stumbling onto this post, I came up with this solution - to toggle the TopMost property:
this.TopMost = true;
this.TopMost = false;
I have this code in my form's constructor, eg:
public MyForm()
{
//...
// Brint-to-front hack
this.TopMost = true;
this.TopMost = false;
//...
}
You can use this. Its Tested code
select {
background: url(http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png) no-repeat right !important;
appearance: none !important;
background-size: 25px 25px !important;
background-position: 99% 50% !important;
}
In any case, you can override height
with max-height
.
Use asp:image
<asp:Image id="Image1" runat="server"
AlternateText="Image text"
ImageAlign="left"
ImageUrl="images/image1.jpg"/>
and codebehind to change image url
Image1.ImageUrl = "/MyProject;component/Images/down.png";
arr.slice(begin[,end])
is non destructive, splice and shift will modify your original array
Git lets you ignore those files by assuming they are unchanged. This is done by running the
git update-index --assume-unchanged path/to/file.txt
command. Once marking a file as such, git will completely ignore any changes on that file; they will not show up when running git status or git diff, nor will they ever be committed.
(From https://help.github.com/articles/ignoring-files)
Hence, not deleting it, but ignoring changes to it forever. I think this only works locally, so co-workers can still see changes to it unless they run the same command as above. (Still need to verify this though.)
Note: This isn't answering the question directly, but is based on follow up questions in the comments of the other answers.
It's a placeholder in the string.
For example,
string b = "world.";
Console.WriteLine("Hello {0}", b);
would produce this output:
Hello world.
Also, you can have as many placeholders as you wish. This also works on String.Format
:
string b = "world.";
string a = String.Format("Hello {0}", b);
Console.WriteLine(a);
And you would still get the very same output.
Take a look at this answer:
from numpy import matrix
from numpy import linalg
A = matrix( [[1,2,3],[11,12,13],[21,22,23]]) # Creates a matrix.
x = matrix( [[1],[2],[3]] ) # Creates a matrix (like a column vector).
y = matrix( [[1,2,3]] ) # Creates a matrix (like a row vector).
print A.T # Transpose of A.
print A*x # Matrix multiplication of A and x.
print A.I # Inverse of A.
print linalg.solve(A, x) # Solve the linear equation system.
When you press enter in a form the natural behaviour of form is to being submited, to stop this behaviour which is not natural, you have to prevent it from submiting( default behaviour), with jquery:
$("#yourFormId").on("submit",function(event){event.preventDefault()})
This fixed issues for me:
<style>

Better to first compress catalog on remote server:

I used the answer by @Spenhouet and added more "replacements"-possibilities than "*". For example "?". Just add your needs to the dict in replaceHelper
.
/**
* @param {string} str
* @param {string} rule
* checks match a string to a rule
* Rule allows * as zero to unlimited numbers and ? as zero to one character
* @returns {boolean}
*/
function matchRule(str, rule) {
const escapeRegex = (str) => str.replace(/([.*+?^=!:${}()|\[\]\/\\])/g, "\\$1");
return new RegExp("^" + replaceHelper(rule, {"*": "\\d*", "?": ".?"}, escapeRegex) + "$").test(str);
}
function replaceHelper(input, replace_dict, last_map) {
if (Object.keys(replace_dict).length === 0) {
return last_map(input);
}
const split_by = Object.keys(replace_dict)[0];
const replace_with = replace_dict[split_by];
delete replace_dict[split_by];
return input.split(split_by).map((next_input) => replaceHelper(next_input, replace_dict, last_map)).join(replace_with);
}

Here is a solution that works in Chrome and Chromium (have only tested these platforms). It seems Chrome has some bug or own approach to handling key codes so this property has to be added separately to the KeyboardEvent.
function simulateKeydown (keycode,isCtrl,isAlt,isShift){
var e = new KeyboardEvent( "keydown", { bubbles:true, cancelable:true, char:String.fromCharCode(keycode), key:String.fromCharCode(keycode), shiftKey:isShift, ctrlKey:isCtrl, altKey:isAlt } );
Object.defineProperty(e, 'keyCode', {get : function() { return this.keyCodeVal; } });
e.keyCodeVal = keycode;
document.dispatchEvent(e);
}
simulateKeydown(39, false, false, false);

@outis's answer is good: concise and correct as regards relations.
However, the situation is slightly more complicated as regards SQL.
Consider the usual suppliers and parts database but implemented in SQL:
SELECT * FROM S NATURAL JOIN SP;
would return a resultset** with columns
SNO, SNAME, STATUS, CITY, PNO, QTY
The join is performed on the column with the same name in both tables, SNO
. Note that the resultset has six columns and only contains one column for SNO
.
Now consider a theta eqijoin, where the column names for the join must be explicitly specified (plus range variables S
and SP
are required):
SELECT * FROM S JOIN SP ON S.SNO = SP.SNO;
The resultset will have seven columns, including two columns for SNO
. The names of the resultset are what the SQL Standard refers to as "implementation dependent" but could look like this:
SNO, SNAME, STATUS, CITY, SNO, PNO, QTY
or perhaps this
S.SNO, SNAME, STATUS, CITY, SP.SNO, PNO, QTY
In other words, NATURAL JOIN
in SQL can be considered to remove columns with duplicated names from the resultset (but alas will not remove duplicate rows - you must remember to change SELECT
to SELECT DISTINCT
yourself).
** I don't quite know what the result of SELECT * FROM table_expression;
is. I know it is not a relation because, among other reasons, it can have columns with duplicate names or a column with no name. I know it is not a set because, among other reasons, the column order is significant. It's not even a SQL table or SQL table expression. I call it a resultset.
Gets the time to wait while trying to establish a connection before terminating the attempt and generating an error. (MSDN, SqlConnection.ConnectionTimeout Property, 2013)
Just for the record it can also happen if you try to use undeclared variable in data like
var layout = {};
$.ajax({
...
data: {
layout: laoyut // notice misspelled variable name
},
...
});
you could use first-of-type
or nth-of-type(1)
.red {_x000D_
color: green; _x000D_
}_x000D_
_x000D_
/* .red:nth-of-type(1) */_x000D_
.red:first-of-type {_x000D_
color: red; _x000D_
}
_x000D_
<div class="home">_x000D_
<span>blah</span>_x000D_
<p class="red">first</p>_x000D_
<p class="red">second</p>_x000D_
<p class="red">third</p>_x000D_
<p class="red">fourth</p>_x000D_
</div>

Your understanding is correct, an artifact in the Jenkins sense is the result of a build - the intended output of the build process.
A common convention is to put the result of a build into a build
, target
or bin
directory.
The Jenkins archiver can use globs (target/*.jar
) to easily pick up the right file even if you have a unique name per build.
Atom does not have block comment by default, so I would recommend searching for atom packages by "block comment" and install the one suits to you.
I prefer https://atom.io/packages/block-comment because is has the closest keyboard shortcut to line comment and it works as i need it to, meaning it would not comment the whole line but only the selected text.
line comment: CTRL+/
block comment: CTRL+SHIFT+/
(with the plugin installed)
If all you need is to ensure uniqueness of elements, then HashSet is what you need.
What do you mean when you say "just a set implementation"? A set is (by definition) a collection of unique elements that doesn't save element order.
Shelving is a way of saving all of the changes on your box without checking in. The changes are persisted on the server. At any later time you or any of your team-mates can "unshelve" them back onto any one of your machines.
It's also great for review purposes. On my team for a check in we shelve up our changes and send out an email with the change description and name of the changeset. People on the team can then view the changeset and give feedback.
FYI: The best way to review a shelveset is with the following command
tfpt review /shelveset:shelvesetName;userName
tfpt is a part of the Team Foundation Power Tools
There are not many good reasons this would fail, especially the regsvr32 step. Run dumpbin /exports on that dll. If you don't see DllRegisterServer then you've got a corrupt install. It should have more side-effects, you wouldn't be able to build C/C++ projects anymore.
One standard failure mode is running this on a 64-bit operating system. This is 32-bit unmanaged code, you would indeed get the 'class not registered' exception. Project + Properties, Build tab, change Platform Target to x86.
If you are hiding the status bar do this in onCreate(for Activity) and onCreateView/onViewCreated(for Fragment)
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
And don't forget to clear the flag when exiting the activity or else you will have the full screen in your whole app after visiting this activity. To clear do this in your onDestroy(for Activity) or onDestroyView(for Fragment)
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)
Just use a Reverse Proxy in your apache configuration (directly):
ProxyPass /foo http://foo.example.com/bar
ProxyPassReverse /foo http://foo.example.com/bar
JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm
page.
One idea is to let the the browser know that it should redirect by adding a redirect
variable to to the resulting object and checking for it in JQuery:
$(document).ready(function(){
jQuery.ajax({
type: "GET",
url: "populateData.htm",
dataType:"json",
data:"userId=SampleUser",
success:function(response){
if (response.redirect) {
window.location.href = response.redirect;
}
else {
// Process the expected results...
}
},
error: function(xhr, textStatus, errorThrown) {
alert('Error! Status = ' + xhr.status);
}
});
});
You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1")
and in JQuery you do on success(!):
//....
success:function(response){
if (response.getResponseHeader('REQUIRES_AUTH') === '1'){
window.location.href = 'login.htm';
}
else {
// Process the expected results...
}
}
//....
Hope that helps.
My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.
when should we use it
Quentin's answer is right: use multipart/form-data
if the form contains a file upload, and application/x-www-form-urlencoded
otherwise, which is the default if you omit enctype
.
I'm going to:
There are three possibilities for enctype
:
application/x-www-form-urlencoded
multipart/form-data
(spec points to RFC7578)text/plain
. This is "not reliably interpretable by computer", so it should never be used in production, and we will not look further into it.Once you see an example of each method, it becomes obvious how they work, and when you should use each one.
You can produce examples using:
nc -l
or an ECHO server: HTTP test server accepting GET/POST requestsSave the form to a minimal .html
file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8"/>
<title>upload</title>
</head>
<body>
<form action="http://localhost:8000" method="post" enctype="multipart/form-data">
<p><input type="text" name="text1" value="text default">
<p><input type="text" name="text2" value="aωb">
<p><input type="file" name="file1">
<p><input type="file" name="file2">
<p><input type="file" name="file3">
<p><button type="submit">Submit</button>
</form>
</body>
</html>
We set the default text value to aωb
, which means a?b
because ?
is U+03C9
, which are the bytes 61 CF 89 62
in UTF-8.
Create files to upload:
echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html
# Binary file containing 4 bytes: 'a', 1, 2 and 'b'.
printf 'a\xCF\x89b' > binary
Run our little echo server:
while true; do printf '' | nc -l 8000 localhost; done
Open the HTML on your browser, select the files and click on submit and check the terminal.
nc
prints the request received.

For the binary file and text field, the bytes 61 CF 89 62
(a?b
in UTF-8) are sent literally. You could verify that with nc -l localhost 8000 | hd
, which says that the bytes:
61 CF 89 62
were sent (61
== 'a' and 62
== 'b').
Therefore it is clear that:
Content-Type: multipart/form-data; boundary=---------------------------735323031399963166993862150
sets the content type to multipart/form-data
and says that the fields are separated by the given boundary
string.
But note that the:
boundary=---------------------------735323031399963166993862150
has two less dadhes --
than the actual barrier
-----------------------------735323031399963166993862150
This is because the standard requires the boundary to start with two dashes --
. The other dashes appear to be just how Firefox chose to implement the arbitrary boundary. RFC 7578 clearly mentions that those two leading dashes --
are required:
4.1. "Boundary" Parameter of multipart/form-data
As with other multipart types, the parts are delimited with a boundary delimiter, constructed using CRLF, "--", and the value of the "boundary" parameter.
every field gets some sub headers before its data: Content-Disposition: form-data;
, the field name
, the filename
, followed by the data.
The server reads the data until the next boundary string. The browser must choose a boundary that will not appear in any of the fields, so this is why the boundary may vary between requests.
Because we have the unique boundary, no encoding of the data is necessary: binary data is sent as is.
TODO: what is the optimal boundary size (log(N)
I bet), and name / running time of the algorithm that finds it? Asked at: https://cs.stackexchange.com/questions/39687/find-the-shortest-sequence-that-is-not-a-sub-sequence-of-a-set-of-sequences
Content-Type
is automatically determined by the browser.
How it is determined exactly was asked at: How is mime type of an uploaded file determined by browser?
Now change the enctype
to application/x-www-form-urlencoded
, reload the browser, and resubmit.
Firefox sent:
POST / HTTP/1.1
[[ Less interesting headers ... ]]
Content-Type: application/x-www-form-urlencoded
Content-Length: 51
text1=text+default&text2=a%CF%89b&file1=a.txt&file2=a.html&file3=binary
Clearly the file data was not sent, only the basenames. So this cannot be used for files.
As for the text field, we see that usual printable characters like a
and b
were sent in one byte, while non-printable ones like 0xCF
and 0x89
took up 3 bytes each: %CF%89
!
File uploads often contain lots of non-printable characters (e.g. images), while text forms almost never do.
From the examples we have seen that:
multipart/form-data
: adds a few bytes of boundary overhead to the message, and must spend some time calculating it, but sends each byte in one byte.
application/x-www-form-urlencoded
: has a single byte boundary per field (&
), but adds a linear overhead factor of 3x for every non-printable character.
Therefore, even if we could send files with application/x-www-form-urlencoded
, we wouldn't want to, because it is so inefficient.
But for printable characters found in text fields, it does not matter and generates less overhead, so we just use it.

The package name can be anything you want it to be, as long as it doesn't contain any reserved keywords in Java
Next you have to create the wsimport.bat script to generate your packaged and code at the preferred location.
cd C:\YOUR\PATH\TO\PLACE\THE\PACKAGES
wsimport -keep -verbose -b "C:\YOUR\PATH\TO\schema.xjb" YOUR_URL?wsdl
pause
If you do not want to use cd, you can put the wsimport.bat in "C:\YOUR\PATH\TO\PLACE\THE\PACKAGES"
If you run it without -keep -verbose it will only generate the packages but not the .java files.
The -b will make sure the schema.xjc is used when generating
If nothing makes sense, this error can also be caused by PHP Error that is embedded inside html/javascript, such as the one below
<br />
<b>Deprecated</b>: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in <b>C:\Projects\rwp\demo\en\super\ge.php</b> on line <b>54</b><br />
var zNodes =[{ id:1, pId:0, name:"ACE", url: "/ace1.php", target:"_self", open:true}
Not the <br />
etc in the code that are inserted into html by PHP is causing the error. To fix this kind of error (suppress warning), used this code in the start
error_reporting(E_ERROR | E_PARSE);
To view, right click on page, "view source" and then examine complete html to spot this error.

The above answer doesn't support observable interpolation (and cost me a lot of time trying to debug). The jsFiddle link in @BrandonTilley comment was the answer that worked for me, which I'll re-post here for preservation:
app.directive('backImg', function(){
return function(scope, element, attrs){
attrs.$observe('backImg', function(value) {
element.css({
'background-image': 'url(' + value +')',
'background-size' : 'cover'
});
});
};
});
Example using controller and template
Controller :
$scope.someID = ...;
/*
The advantage of using directive will also work inside an ng-repeat :
someID can be inside an array of ID's
*/
$scope.arrayOfIDs = [0,1,2,3];
Template :
Use in template like so :
<div back-img="img/service-sliders/{{someID}}/1.jpg"></div>
or like so :
<div ng-repeat="someID in arrayOfIDs" back-img="img/service-sliders/{{someID}}/1.jpg"></div>
Embarrassing to say it, but when I had this problem, it was simply a mistake that I was closing the connection before I read all the data. In cases with small strings being returned, it worked, but that was probably due to the whole response was buffered, before I closed it.
In cases of longer amounts of text being returned, the exception was thrown, since more then a buffer was coming back.
You might check for this oversight. Remember opening a URL is like a file, be sure to close it (release the connection) once it has been fully read.
You don't need to use the background animate plugin if you just use separate values like this:

SWT was created as a response to the sluggishness of Swing around the turn of the century. Now that the differences in performance are becoming negligable, I think Swing is a better option for your standard applications. SWT/Eclipse has a nice framework which helps with a lot of boiler plate code.
Just discovered that :
next(iter(myList), 5)
iter(l)
returns an iterator on myList
, next()
consumes the first element of the iterator, and raises a StopIteration
error except if called with a default value, which is the case here, the second argument, 5
This only works when you want the 1st element, which is the case in your example, but not in the text of you question, so...
Additionally, it does not need to create temporary lists in memory and it works for any kind of iterable, even if it does not have a name (see Xiong Chiamiov's comment on gruszczy's answer)
I use a CSS fix rather than JS to workaround my round cornered layer with transparent PNG inside

This may require more work on ie9 or later.
For those who don't know about Clockwise/Spiral Rule: Start from the name of the variable, move clockwisely (in this case, move backward) to the next pointer or type. Repeat until expression ends.
Here is a demo:
You can try something like this:
public interface PersonRepository extends CrudRepository<Person, Long> {
@Query("select p from Person AS p"
+ " ,Name AS n"
+ " where p.forename = n.forename "
+ " and p.surname = n.surname"
+ " and n = :name")
Set<Person>findByName(@Param("name") Name name);
}
You can try to get the list of all elements with class = "content"
by using find_elements_by_class_name:
a = driver.find_elements_by_class_name("content")
Then you can click on the link that you are looking for.
I know this is an old question, but with my quick read of the responses here, I didn't really see anyone mention that at times a synchronized
method may be the wrong lock.
From Java Concurrency In Practice (pg. 72):
public class ListHelper<E> {
public List<E> list = Collections.syncrhonizedList(new ArrayList<>());
...
public syncrhonized boolean putIfAbsent(E x) {
boolean absent = !list.contains(x);
if(absent) {
list.add(x);
}
return absent;
}
The above code has the appearance of being thread-safe. However, in reality it is not. In this case the lock is obtained on the instance of the class. However, it is possible for the list to be modified by another thread not using that method. The correct approach would be to use
public boolean putIfAbsent(E x) {
synchronized(list) {
boolean absent = !list.contains(x);
if(absent) {
list.add(x);
}
return absent;
}
}
The above code would block all threads trying to modify list from modifying the list until the synchronized block has completed.

You should indeed start with the Mandelbrot set, and understand what it really is.
The idea behind it is relatively simple. You start with a function of complex variable
f(z) = z2 + C
where z is a complex variable and C is a complex constant. Now you iterate it starting from z = 0, i.e. you compute z1 = f(0), z2 = f(z1), z3 = f(z2) and so on. The set of those constants C for which the sequence z1, z2, z3, ... is bounded, i.e. it does not go to infinity, is the Mandelbrot set (the black set in the figure on the Wikipedia page).
In practice, to draw the Mandelbrot set you should:
The astounding fact about fractals is how we can obtain a tremendously complex set (in particular, the frontier of the Mandelbrot set) from easy and apparently innocuous requirements.

Adding public key is the solution.For generating ssh keys: https://help.github.com/articles/generating-ssh-keys has step by step instructions.
However, the problem can persist if key is not generated in the correct way. I found this to be a useful link too: https://help.github.com/articles/error-permission-denied-publickey
In my case the problem was that I was generating the ssh-key without using sudo but when using git commands I needed to use sudo. This comment in the above link "If you generate SSH keys without sudo, then when you try to use a command like sudo git push, you won't be using the SSH key you generated." helped me.
So, the solution was that I had to use sudo with both key generating commands and git commands. Or for others, when they don't need sudo anywhere, do not use it in any of the two steps. (key generating and git commands).
Try the following:
cv::Mat image = ...do some stuff...;
image.at<cv::Vec3b>(y,x);
gives you the RGB (it might be ordered as BGR) vector of type cv::Vec3b
image.at<cv::Vec3b>(y,x)[0] = newval[0];
image.at<cv::Vec3b>(y,x)[1] = newval[1];
image.at<cv::Vec3b>(y,x)[2] = newval[2];
Arrays and Objects are passed by reference or by value based on these conditions:
if you are setting the value of an object or array it is Pass by Value.
object1 = {prop: "car"};
array1 = [1,2,3];
if you are changing a property value of an object or array then it is Pass by Reference.
object1.prop = "car";
array1[0] = 9;
Code
function passVar(obj1, obj2, num) {_x000D_
obj1.prop = "laptop"; // will CHANGE original_x000D_
obj2 = { prop: "computer" }; //will NOT affect original_x000D_
num = num + 1; // will NOT affect original_x000D_
}_x000D_
_x000D_
var object1 = {_x000D_
prop: "car"_x000D_
};_x000D_
var object2 = {_x000D_
prop: "bike"_x000D_
};_x000D_
var number1 = 10;_x000D_
_x000D_
passVar(object1, object2, number1);_x000D_
console.log(object1); //output: Object {item:"laptop"}_x000D_
console.log(object2); //output: Object {item:"bike"}_x000D_
console.log(number1); //ouput: 10

Oneliner to solve your problem. I assume you will store your URL in myURL string. Add this line and you are done. myURL = myURL.replace("http", "https");
for those stumbling upon this question: the python jsonlines
library (much younger than this question) elegantly handles files with one json document per line. see https://jsonlines.readthedocs.io/

Why do you want to use sprintf
for string concatenation when there are methods intended specifically for what you need such as strcat
and strncat
?
Add a CommandName attribute, and optionally a CommandArgument attribute, to your LinkButton control. Then set the OnCommand attribute to the name of your Command event handler.
<asp:LinkButton ID="ENameLinkBtn" runat="server" CommandName="MyValueGoesHere" CommandArgument="OtherValueHere"
style="font-weight: 700; font-size: 8pt;" OnCommand="ENameLinkBtn_Command" ><%# Eval("EName") %></asp:LinkButton>
<asp:Label id="Label1" runat="server"/>
Then it will be available when in your handler:
protected void ENameLinkBtn_Command (object sender, CommandEventArgs e)
{
Label1.Text = "You chose: " + e.CommandName + " Item " + e.CommandArgument;
}

There are two ways to do it.
In the method that opens the dialog, pass in the following configuration option disableClose
as the second parameter in MatDialog#open()
and set it to true
:
export class AppComponent {
constructor(private dialog: MatDialog){}
openDialog() {
this.dialog.open(DialogComponent, { disableClose: true });
}
}
Alternatively, do it in the dialog component itself.
export class DialogComponent {
constructor(private dialogRef: MatDialogRef<DialogComponent>){
dialogRef.disableClose = true;
}
}
Here's what you're looking for:
And here's a Stackblitz demo
Here's some other use cases and code snippets of how to implement them.
As what @MarcBrazeau said in the comment below my answer, you can allow the esc key to close the modal but still disallow clicking outside the modal. Use this code on your dialog component:
import { Component, OnInit, HostListener } from '@angular/core';
import { MatDialogRef } from '@angular/material';
@Component({
selector: 'app-third-dialog',
templateUrl: './third-dialog.component.html'
})
export class ThirdDialogComponent {
constructor(private dialogRef: MatDialogRef<ThirdDialogComponent>) {
}
@HostListener('window:keyup.esc') onKeyUp() {
this.dialogRef.close();
}
}
P.S. This is an answer which originated from this answer, where the demo was based on this answer.
To prevent the esc key from closing the dialog but allow clicking on the backdrop to close, I've adapted Marc's answer, as well as using MatDialogRef#backdropClick
to listen for click events to the backdrop.
Initially, the dialog will have the configuration option disableClose
set as true
. This ensures that the esc
keypress, as well as clicking on the backdrop will not cause the dialog to close.
Afterwards, subscribe to the MatDialogRef#backdropClick
method (which emits when the backdrop gets clicked and returns as a MouseEvent
).
Anyways, enough technical talk. Here's the code:
openDialog() {
let dialogRef = this.dialog.open(DialogComponent, { disableClose: true });
/*
Subscribe to events emitted when the backdrop is clicked
NOTE: Since we won't actually be using the `MouseEvent` event, we'll just use an underscore here
See https://stackoverflow.com/a/41086381 for more info
*/
dialogRef.backdropClick().subscribe(() => {
// Close the dialog
dialogRef.close();
})
// ...
}
Alternatively, this can be done in the dialog component:
export class DialogComponent {
constructor(private dialogRef: MatDialogRef<DialogComponent>) {
dialogRef.disableClose = true;
/*
Subscribe to events emitted when the backdrop is clicked
NOTE: Since we won't actually be using the `MouseEvent` event, we'll just use an underscore here
See https://stackoverflow.com/a/41086381 for more info
*/
dialogRef.backdropClick().subscribe(() => {
// Close the dialog
dialogRef.close();
})
}
}
file.delete();
if the file doesn't exist, it will return false.
mAddTaskButton
is null because you never initialize it with:
mAddTaskButton = (Button) findViewById(R.id.addTaskButton);
before you call mAddTaskButton.setOnClickListener()
.

better to use touchstart
event with .on()
jQuery method:
$(window).load(function() { // better to use $(document).ready(function(){
$('.List li').on('click touchstart', function() {
$('.Div').slideDown('500');
});
});
And i don't understand why you are using $(window).load()
method because it waits for everything on a page to be loaded, this tend to be slow, while you can use $(document).ready()
method which does not wait for each element on the page to be loaded first.
Have you tried libconfig; very JSON-like syntax. I prefer it over XML configuration files.

I really like @luke-schafer's prototype idea, but also hear what he is saying about the issues with prototypes. What about using a simple function?
function sortKeysAndDo( obj, worker ) {_x000D_
var keys = Object.keys(obj);_x000D_
keys.sort();_x000D_
for (var i = 0; i < keys.length; i++) {_x000D_
worker(keys[i], obj[keys[i]]);_x000D_
}_x000D_
}_x000D_
_x000D_
function show( key, value ) {_x000D_
document.write( key + ' : ' + value +'<br>' );_x000D_
}_x000D_
_x000D_
var a = new Array();_x000D_
a['b'] = 1;_x000D_
a['z'] = 1;_x000D_
a['a'] = 1;_x000D_
_x000D_
sortKeysAndDo( a, show);_x000D_
_x000D_
var my_object = { 'c': 3, 'a': 1, 'b': 2 };_x000D_
_x000D_
sortKeysAndDo( my_object, show);
_x000D_
This seems to eliminate the issues with prototypes and still provide a sorted iterator for objects. I am not really a JavaScript guru, though, so I'd love to know if this solution has hidden flaws I missed.
Not sure why your current code isn't working but if you don't specifically need a date object this will work:
$first_date = strtotime($date_raw);
$second_date = strtotime('-1 day', $first_date);
print 'First Date ' . date('Y-m-d', $first_date);
print 'Next Date ' . date('Y-m-d', $second_date);
use .serializeArray() to get the data in array format and then convert it into an object:
function getFormObj(formId) {
var formObj = {};
var inputs = $('#'+formId).serializeArray();
$.each(inputs, function (i, input) {
formObj[input.name] = input.value;
});
return formObj;
}
I tried to install scikit-image but got the following error when I tried to install the .whl file even though my installed version of python was 2.7 32-bit. scikit_image-0.12.3-cp27-cp27m-win32.whl is not a supported wheel on this platform.
However I also got this message before the error message:
You are using pip version 7.1.0, however version 8.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
I then ran the command python -m pip install --upgrade pip
and then pip install scikit_image-0.12.3-cp27-cp27m-win32.whl
worked fine. I hope this can help someone!
The simple way to do so is :
Attr function (since jQuery version 1.0)
$("a").attr("href", "https://stackoverflow.com/")
or
Prop function (since jQuery version 1.6)
$("a").prop("href", "https://stackoverflow.com/")
Also, the advantage of above way is that if selector selects a single anchor, it will update that anchor only and if selector returns a group of anchor, it will update the specific group through one statement only.
Now, there are lot of ways to identify exact anchor or group of anchors:
Quite Simple Ones:
$("a")
$("a:eq(0)")
active
) : $("a.active")
profileLink
ID) : $("a#proileLink")
$("a:first")
More useful ones:
$("[href]")
$("a[href='www.stackoverflow.com']")
$("a[href!='www.stackoverflow.com']")
$("a[href*='www.stackoverflow.com']")
$("a[href^='www.stackoverflow.com']")
$("a[href$='www.stackoverflow.com']")
Now, if you want to amend specific URLs, you can do that as:
For instance if you want to add proxy website for all the URLs going to google.com, you can implement it as follows:
$("a[href^='http://www.google.com']")
.each(function()
{
this.href = this.href.replace(/http:\/\/www.google.com\//gi, function (x) {
return "http://proxywebsite.com/?query="+encodeURIComponent(x);
});
});
Here is some text from MSDN about unmanaged code.
Some library code needs to call into unmanaged code (for example, native code APIs, such as Win32). Because this means going outside the security perimeter for managed code, due caution is required.
Here is some other complimentary explication about Managed code:
For your problem:
I think it's because NUnit execute your code for UnitTesting and might have some part of it that is unmanaged. But I am not sure about it, so do not take this for gold. I am sure someone will be able to give you more information about it. Hope it helps!
you should not use Integer[]
array inside the list as arraylist itself is a kind of array. Just leave the []
and it should work
<p>31<sup>st</sup> March 2015</p>

You can use
1<sup>st</sup>
2<sup>nd</sup>
3<sup>rd</sup>
4<sup>th</sup>
for positioning the suffix

Based on Kiril V. Lyadvinsky answer, I made a new version. This snippet use template and overloading. With it, you can write vector3 = vector1 + vector2
and vector4 += vector3
. Hope it can help.
template <typename T>
std::vector<T> operator+(const std::vector<T> &A, const std::vector<T> &B)
{
std::vector<T> AB;
AB.reserve(A.size() + B.size()); // preallocate memory
AB.insert(AB.end(), A.begin(), A.end()); // add A;
AB.insert(AB.end(), B.begin(), B.end()); // add B;
return AB;
}
template <typename T>
std::vector<T> &operator+=(std::vector<T> &A, const std::vector<T> &B)
{
A.reserve(A.size() + B.size()); // preallocate memory without erase original data
A.insert(A.end(), B.begin(), B.end()); // add B;
return A; // here A could be named AB
}
using webpack and vue loader you can do something like this
it waits for the external script to load before creating the component, so globar vars etc are available in the component
components: {
SomeComponent: () => {
return new Promise((resolve, reject) => {
let script = document.createElement('script')
script.onload = () => {
resolve(import(someComponent))
}
script.async = true
script.src = 'https://maps.googleapis.com/maps/api/js?key=APIKEY&libraries=places'
document.head.appendChild(script)
})
}
},
This simple one-liner should work in any shell, not just bash:
ls -1q log* | wc -l
ls -1q will give you one line per file, even if they contain whitespace or special characters such as newlines.
The output is piped to wc -l, which counts the number of lines.
::
is called Method Reference. It is basically a reference to a single method. I.e. it refers to an existing method by name.
Short Explanation:
Below is an example of a reference to a static method:
class Hey {
public static double square(double num){
return Math.pow(num, 2);
}
}
Function<Double, Double> square = Hey::square;
double ans = square.apply(23d);
square
can be passed around just like object references and triggered when needed. In fact, it can be just as easily used as a reference to "normal" methods of objects as static
ones. For example:
class Hey {
public double square(double num) {
return Math.pow(num, 2);
}
}
Hey hey = new Hey();
Function<Double, Double> square = hey::square;
double ans = square.apply(23d);
Function
above is a functional interface. To fully understand ::
, it is important to understand functional interfaces as well. Plainly, a functional interface is an interface with just one abstract method.
Examples of functional interfaces include Runnable
, Callable
, and ActionListener
.
Function
above is a functional interface with just one method: apply
. It takes one argument and produces a result.
The reason why ::
s are awesome is that:
Method references are expressions which have the same treatment as lambda expressions (...), but instead of providing a method body, they refer an existing method by name.
E.g. instead of writing the lambda body
Function<Double, Double> square = (Double x) -> x * x;
You can simply do
Function<Double, Double> square = Hey::square;
At runtime, these two square
methods behave exactly the same as each other. The bytecode may or may not be the same (though, for the above case, the same bytecode is generated; compile the above and check with javap -c
).
The only major criterion to satisfy is: the method you provide should have a similar signature to the method of the functional interface you use as object reference.
The below is illegal:
Supplier<Boolean> p = Hey::square; // illegal
square
expects an argument and returns a double
. The get
method in Supplier returns a value but does not take an argument. Thus, this results in an error.
A method reference refers to the method of a functional interface. (As mentioned, functional interfaces can have only one method each).
Some more examples: the accept
method in Consumer takes an input but doesn't return anything.
Consumer<Integer> b1 = System::exit; // void exit(int status)
Consumer<String[]> b2 = Arrays::sort; // void sort(Object[] a)
Consumer<String> b3 = MyProgram::main; // void main(String... args)
class Hey {
public double getRandom() {
return Math.random();
}
}
Callable<Double> call = hey::getRandom;
Supplier<Double> call2 = hey::getRandom;
DoubleSupplier sup = hey::getRandom;
// Supplier is functional interface that takes no argument and gives a result
Above, getRandom
takes no argument and returns a double
. So any functional interface that satisfies the criteria of: take no argument and return double
can be used.
Another example:
Set<String> set = new HashSet<>();
set.addAll(Arrays.asList("leo","bale","hanks"));
Predicate<String> pred = set::contains;
boolean exists = pred.test("leo");
In case of parameterized types:
class Param<T> {
T elem;
public T get() {
return elem;
}
public void set(T elem) {
this.elem = elem;
}
public static <E> E returnSame(E elem) {
return elem;
}
}
Supplier<Param<Integer>> obj = Param<Integer>::new;
Param<Integer> param = obj.get();
Consumer<Integer> c = param::set;
Supplier<Integer> s = param::get;
Function<String, String> func = Param::<String>returnSame;
Method references can have different styles, but fundamentally they all mean the same thing and can simply be visualized as lambdas:
ClassName::methName
)instanceRef::methName
)super::methName
)ClassName::methName
)ClassName::new
)TypeName[]::new

.if you just want diff the specified file, you can :
git diff master 766eceb -- connections/ > 000-mysql-connector.patch
It's your choice. There are basically three ways in a Java web application archive (WAR):
So that you can load it by ClassLoader#getResourceAsStream()
with a classpath-relative path:
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
InputStream input = classLoader.getResourceAsStream("foo.properties");
// ...
Properties properties = new Properties();
properties.load(input);
Here foo.properties
is supposed to be placed in one of the roots which are covered by the default classpath of a webapp, e.g. webapp's /WEB-INF/lib
and /WEB-INF/classes
, server's /lib
, or JDK/JRE's /lib
. If the propertiesfile is webapp-specific, best is to place it in /WEB-INF/classes
. If you're developing a standard WAR project in an IDE, drop it in src
folder (the project's source folder). If you're using a Maven project, drop it in /main/resources
folder.
You can alternatively also put it somewhere outside the default classpath and add its path to the classpath of the appserver. In for example Tomcat you can configure it as shared.loader
property of Tomcat/conf/catalina.properties
.
If you have placed the foo.properties
it in a Java package structure like com.example
, then you need to load it as below
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
InputStream input = classLoader.getResourceAsStream("com/example/foo.properties");
// ...
Note that this path of a context class loader should not start with a /
. Only when you're using a "relative" class loader such as SomeClass.class.getClassLoader()
, then you indeed need to start it with a /
.
ClassLoader classLoader = getClass().getClassLoader();
InputStream input = classLoader.getResourceAsStream("/com/example/foo.properties");
// ...
However, the visibility of the properties file depends then on the class loader in question. It's only visible to the same class loader as the one which loaded the class. So, if the class is loaded by e.g. server common classloader instead of webapp classloader, and the properties file is inside webapp itself, then it's invisible. The context class loader is your safest bet so you can place the properties file "everywhere" in the classpath and/or you intend to be able to override a server-provided one from the webapp on.
So that you can load it by ServletContext#getResourceAsStream()
with a webcontent-relative path:
InputStream input = getServletContext().getResourceAsStream("/WEB-INF/foo.properties");
// ...
Note that I have demonstrated to place the file in /WEB-INF
folder, otherwise it would have been public accessible by any webbrowser. Also note that the ServletContext
is in any HttpServlet
class just accessible by the inherited GenericServlet#getServletContext()
and in Filter
by FilterConfig#getServletContext()
. In case you're not in a servlet class, it's usually just injectable via @Inject
.
So that you can load it the usual java.io
way with an absolute local disk file system path:
InputStream input = new FileInputStream("/absolute/path/to/foo.properties");
// ...
Note the importance of using an absolute path. Relative local disk file system paths are an absolute no-go in a Java EE web application. See also the first "See also" link below.
Just weigh the advantages/disadvantages in your own opinion of maintainability.
If the properties files are "static" and never needs to change during runtime, then you could keep them in the WAR.
If you prefer being able to edit properties files from outside the web application without the need to rebuild and redeploy the WAR every time, then put it in the classpath outside the project (if necessary add the directory to the classpath).
If you prefer being able to edit properties files programmatically from inside the web application using Properties#store()
method, put it outside the web application. As the Properties#store()
requires a Writer
, you can't go around using a disk file system path. That path can in turn be passed to the web application as a VM argument or system property. As a precaution, never use getRealPath()
. All changes in deploy folder will get lost on a redeploy for the simple reason that the changes are not reflected back in original WAR file.
For Development purpose you can just export the required tables data into a single HTML and make a direct search on it.
Embed the video player and use CSS to hide the video. If you do it properly you may even be able to hide only the video and not the controls below it.
However, I'd recommend against it, because it will be a violation of YouTube TOS. Use your own server instead if you really want to play only audio.
The option to save the .orig file can be disabled by configuring KDiff3
A simple solution is the library factoextra
. You can change the clustering method and the method for calculate the best number of groups. For example if you want to know the best number of clusters for a k- means:
library(factoextra)
fviz_nbclust(mtcars, kmeans, method = "wss") +
geom_vline(xintercept = 3, linetype = 2)+
labs(subtitle = "Elbow method")
Finally, we get a graph like:

I'll slightly expand @assylias answer to take time zone into account. There are at least two ways to get LocalDateTime for specific time zone.
You can use setDefault time zone for whole application. It should be called before any timestamp -> java.time conversion:
public static void main(String... args) {
TimeZone utcTimeZone = TimeZone.getTimeZone("UTC");
TimeZone.setDefault(utcTimeZone);
...
timestamp.toLocalDateTime().toLocalDate();
}
Or you can use toInstant.atZone chain:
timestamp.toInstant()
.atZone(ZoneId.of("UTC"))
.toLocalDate();
The range() built-in function returns a sequence of integer values, I'm afraid, so you can't use it to do a decimal step.
I'd say just use a while loop:
i = 0.0
while i <= 1.0:
print i
i += 0.1
If you're curious, Python is converting your 0.1 to 0, which is why it's telling you the argument can't be zero.

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.
When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.
An example of a DATE subtraction resulting in a positive integer difference:
select date '2009-08-07' - date '2008-08-08' from dual;
Results in:
DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
364
select dump(date '2009-08-07' - date '2008-08-08') from dual;
DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0
Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.
An example of a DATE subtraction resulting in a negative integer difference:
select date '1000-08-07' - date '2008-08-08' from dual;
Results in:
DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
-368160
select dump(date '1000-08-07' - date '2008-08-08') from dual;
DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0
Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.
An example of a DATE subtraction resulting in a decimal difference:
select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
- to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;
TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
.25
The difference between those 2 dates is 0.25 days or 6 hours.
select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
- to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;
DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0
Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.
Hope this helps anyone who was wondering how a DATE subtraction is actually stored.
You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:
SQL> SELECT DUMP(SYSDATE - start_date) from test;
DUMP(SYSDATE-START_DATE)
--------------------------------------
Typ=14 Len=8: 188,10,0,0,223,65,1,0
You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function
For example:
SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;
(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000
SQL> SELECT (SYSDATE - start_date) from test;
(SYSDATE-START_DATE)
--------------------
2748.9515
SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;
NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000
SQL>
Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.
The array form of new-expression accepts only one form of initializer: an empty ()
. This, BTW, has the same effect as the empty {}
in your non-dynamic initialization.
The above applies to pre-C++11 language. Starting from C++11 one can use uniform initialization syntax with array new-expressions
char* c = new char[length]{};
char* d = new char[length]{ 'a', 'b', 'c' };
I encountered this insertion performance problem as well. My solution is spawn some go routines to finish the insertion work. In the meantime, SetMaxOpenConns
should be given a proper number otherwise too many open connection error would be alerted.
db, _ := sql.open()
db.SetMaxOpenConns(SOME CONFIG INTEGER NUMBER)
var wg sync.WaitGroup
for _, query := range queries {
wg.Add(1)
go func(msg string) {
defer wg.Done()
_, err := db.Exec(msg)
if err != nil {
fmt.Println(err)
}
}(query)
}
wg.Wait()
The loading speed is much faster for my project. This code snippet just gave an idea how it works. Readers should be able to modify it easily.
In jQuery, you can use:
let myObject = {first:1, second:12, third:5};
jQuery.param(myObject);
Doc: http://api.jquery.com/jquery.param/ The output: first=1&second=12&third=5 This will format it, whatever your object contain.
std::is_same()
is only available since C++11. For pre-C++11 you can use typeid()
:
template <typename T>
void foo()
{
if (typeid(T) == typeid(animal)) { /* ... */ }
}
One way to handle this is to create a new BufferedImage, and tell it's graphics object to draw your scaled image into the new BufferedImage:
final float FACTOR = 4f;
BufferedImage img = ImageIO.read(new File("graphic.png"));
int scaleX = (int) (img.getWidth() * FACTOR);
int scaleY = (int) (img.getHeight() * FACTOR);
Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);
BufferedImage buffered = new BufferedImage(scaleX, scaleY, TYPE);
buffered.getGraphics().drawImage(image, 0, 0 , null);
That should do the trick without casting.
Tested these options with python3.5 and pip 9.0.3:
pip install --target /myfolder [packages]
Installs ALL packages including dependencies under /myfolder. Does not take into account that dependent packages are already installed elsewhere in Python. You will find packages from /myfolder/[package_name]. In case you have multiple Python versions, this doesn't take that into account (no Python version in package folder name).
pip install --prefix /myfolder [packages]
Checks are dependencies already installed. Will install packages into /myfolder/lib/python3.5/site-packages/[packages]
pip install --root /myfolder [packages]
Checks dependencies like --prefix but install location will be /myfolder/usr/local/lib/python3.5/site-packages/[package_name].
pip install --user [packages]
Will install packages into $HOME: /home/[USER]/.local/lib/python3.5/site-packages Python searches automatically from this .local path so you don't need to put it to your PYTHONPATH.
=> In most of the cases --user is the best option to use. In case home folder can't be used because of some reason then --prefix.
Let me explain a bit by bit.

man your container is 40% of the width of the parent element
but when you use position:fixed, the width is based on viewport(document) width...
thinking about, i realized your parent element have 10% padding(left and right), it means your element have 80% of the total page width. so your fixed element must have 40% based on 80% of total width
so you just need to change your #fixed class to
#fixed{
position:fixed;
width: calc(80% * 0.4);
height:10px;
background-color:#333;
}
if you use sass, postcss or another css compiler, you can use variables to avoid breaking the layout when you change the padding value of parent element.
here is the updated fiddle http://jsfiddle.net/C93mk/2343/
i hope it helps, regards
While rolling stone's answer is good, straightforward and functional, I think there are two things it does not solve.
Introduce the content types framework, which exposes some objects that allow us to create a "generic foreign key" on the PhoneNumber model. Then, we can define the reverse relationship on Dude and Business
from django.contrib.contenttypes.fields import GenericForeignKey, GenericRelation
from django.contrib.contenttypes.models import ContentType
from django.db import models
class PhoneNumber(models.Model):
number = models.CharField()
content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
object_id = models.PositiveIntegerField()
owner = GenericForeignKey()
class Dude(models.Model):
numbers = GenericRelation(PhoneNumber)
class Business(models.Model):
numbers = GenericRelation(PhoneNumber)
See the docs for details, and perhaps check out this article for a quick tutorial.
Also, here is an article that argues against the use of Generic FKs.
I found this page with detailed instructions to upgrade Anaconda to a major newer version of Python (from Anaconda 4.0+). First,
conda update conda
conda remove argcomplete conda-manager
I also had to conda remove
some packages not on the official list:
Depending on packages installed on your system, you may get additional UnsatisfiableError
errors - simply add those packages to the remove list. Next, install the version of Python,
conda install python==3.6
which takes a while, after which a message indicated to conda install anaconda-client
, so I did
conda install anaconda-client
which said it's already there. Finally, following the directions,
conda update anaconda
I did this in the Windows 10 command prompt, but things should be similar in Mac OS X.
I do below and check if id
exist and execute function if exist.
var divIDVar = $('#divID').length;
if (divIDVar === 0){
console.log('No DIV Exist');
} else{
FNCsomefunction();
}
git remote rename origin upstream
git remote add origin URL_TO_GITHUB_REPO
git push origin master
Now you can work with it just like any other github repo. To pull in patches from upstream, simply run git pull upstream master && git push origin master
.
Just subclass long
(or float
, or whatever). This is highly practical, because this way you can still use your numbers in math ops (and therefore existing code), but they will all print nicely in your terminal.
>>> class number(long):
def __init__(self, value):
self = value
def __repr__(self):
s = str(self)
l = [x for x in s if x in '1234567890']
for x in reversed(range(len(s)-1)[::3]):
l.insert(-x, ',')
l = ''.join(l[1:])
return ('-'+l if self < 0 else l)
>>> number(-100000)
-100,000
>>> number(-100)
-100
>>> number(-12345)
-12,345
>>> number(928374)
928,374
>>> 345

hasNext
somewhat translates to the StopIteration
exception, e.g.:
>>> it = iter("hello")
>>> it.next()
'h'
>>> it.next()
'e'
>>> it.next()
'l'
>>> it.next()
'l'
>>> it.next()
'o'
>>> it.next()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

docs: http://docs.python.org/library/exceptions.html#exceptions.StopIterationThis worked for me to move from Ubuntu 12.04 (Jenkins ver. 1.628) to Ubuntu 16.04 (Jenkins ver. 1.651.2). I first installed Jenkins from the repositories.
Copy JENKINS_HOME
(e.g. /var/lib/jenkins) from the old server to the new one. From a console in the new server:
rsync -av username@old-server-IP:/var/lib/jenkins/ /var/lib/jenkins/
You might not need this, but I had to
Manage Jenkins
and Reload Configuration from Disk
.Configure System > Jenkins Location
, the Jenkins URL
is correctly assigned to the new Jenkins server.Use cell arrays. This has an advantage over 3D arrays in that it does not require a contiguous memory space to store all the matrices. In fact, each matrix can be stored in a different space in memory, which will save you from Out-of-Memory errors if your free memory is fragmented. Here is a sample function to create your matrices in a cell array:
function result = createArrays(nArrays, arraySize)
result = cell(1, nArrays);
for i = 1 : nArrays
result{i} = zeros(arraySize);
end
end
To use it:
myArray = createArrays(requiredNumberOfArrays, [500 800]);
And to access your elements:
myArray{1}(2,3) = 10;
If you can't know the number of matrices in advance, you could simply use MATLAB's dynamic indexing to make the array as large as you need. The performance overhead will be proportional to the size of the cell array, and is not affected by the size of the matrices themselves. For example:
myArray{1} = zeros(500, 800);
if twoRequired, myArray{2} = zeros(500, 800); end
Do not mix CSS/JQuery syntax (#
for identifier) with native JS.
Native JS solution:
document.getElementById("_1234").checked = true;
JQuery solution:
$("#_1234").prop("checked", true);
What have you tried, what was the problem?
Creating DataColumns
and add values to a DataTable
is straight forward:
Dim dt = New DataTable()
Dim dcID = New DataColumn("ID", GetType(Int32))
Dim dcName = New DataColumn("Name", GetType(String))
dt.Columns.Add(dcID)
dt.Columns.Add(dcName)
For i = 1 To 1000
dt.Rows.Add(i, "Row #" & i)
Next
Edit:
If you want to read a xml file and load a DataTable from it, you can use DataTable.ReadXml
.
if you have null value then in doing mathematical operation you will get this error to resolve it use df[~df['x'].isnull()]df[['x']].astype(int)
if you want your dataset to be unchangeable.
Not with pure CSS. The closest equivalent is this:
.class1, .class2 {
some stuff
}
.class2 {
some more stuff
}
