To check if a specific tab page is the currently selected page of a tab control is easy; just use the SelectedTab property of the tab control:
if (tabControl1.SelectedTab == someTabPage)
{
// Do stuff here...
}
This is more useful if the code is executed based on some event other than the tab page being selected (in which case SelectedIndexChanged would be a better choice).
For example I have an application that uses a timer to regularly poll stuff over TCP/IP connection, but to avoid unnecessary TCP/IP traffic I only poll things that update GUI controls in the currently selected tab page.
For Windows Smart device (compact frame work ) (MC75-Motorola devices)
mytabControl.SelectedIndex = 1
I combined the answer from @Jack Griffin and the one from @amazedsaint (the dotnetspider code snippet respectively) into a single TabControlHelper.
The TabControlHelper lets you:
public class TabControlHelper
{
private TabControl _tabControl;
private List<KeyValuePair<TabPage, int>> _pagesIndexed;
public TabControlHelper(TabControl tabControl)
{
_tabControl = tabControl;
_pagesIndexed = new List<KeyValuePair<TabPage, int>>();
for (int i = 0; i < tabControl.TabPages.Count; i++)
{
_pagesIndexed.Add(new KeyValuePair<TabPage, int> (tabControl.TabPages[i], i ));
}
}
public void HideAllPages()
{
for (int i = 0; i < _pagesIndexed.Count; i++)
{
_tabControl.TabPages.Remove(_pagesIndexed[i].Key);
}
}
public void ShowAllPages()
{
for (int i = 0; i < _pagesIndexed.Count; i++)
{
_tabControl.TabPages.Add(_pagesIndexed[i].Key);
}
}
public void HidePage(TabPage tabpage)
{
if (!_tabControl.TabPages.Contains(tabpage)) return;
_tabControl.TabPages.Remove(tabpage);
}
public void ShowPage(TabPage tabpage)
{
if (_tabControl.TabPages.Contains(tabpage)) return;
InsertTabPage(GetTabPage(tabpage).Key, GetTabPage(tabpage).Value);
}
private void InsertTabPage(TabPage tabpage, int index)
{
if (index < 0 || index > _tabControl.TabCount)
throw new ArgumentException("Index out of Range.");
_tabControl.TabPages.Add(tabpage);
if (index < _tabControl.TabCount - 1)
do
{
SwapTabPages(tabpage, (_tabControl.TabPages[_tabControl.TabPages.IndexOf(tabpage) - 1]));
}
while (_tabControl.TabPages.IndexOf(tabpage) != index);
_tabControl.SelectedTab = tabpage;
}
private void SwapTabPages(TabPage tabpage1, TabPage tabpage2)
{
if (_tabControl.TabPages.Contains(tabpage1) == false || _tabControl.TabPages.Contains(tabpage2) == false)
throw new ArgumentException("TabPages must be in the TabControls TabPageCollection.");
int Index1 = _tabControl.TabPages.IndexOf(tabpage1);
int Index2 = _tabControl.TabPages.IndexOf(tabpage2);
_tabControl.TabPages[Index1] = tabpage2;
_tabControl.TabPages[Index2] = tabpage1;
}
private KeyValuePair<TabPage, int> GetTabPage(TabPage tabpage)
{
return _pagesIndexed.Where(p => p.Key == tabpage).First();
}
}
Like the other answer says, in the left hand side select Products and add product. Then select Facbook Login.
I then added http://localhost:3000/ to the field 'Valid OAuth redirect URIs', and then everything worked.
Someone merged the C# answer into this one so I have to post my answer here. I didn't love the other solutions so I made a helper class that will make it easier to hide / show your tabs while retaining the order of tabs.
/// <summary>
/// Memorizes the order of tabs upon creation to make hiding / showing tabs more
/// straightforward. Instead of interacting with the TabCollection, use this class
/// instead.
/// </summary>
public class TabPageHelper
{
private List<TabPage> _allTabs;
private TabControl.TabPageCollection _tabCollection;
public Dictionary<string, int> TabOrder { get; private set; }
public TabPageHelper( TabControl.TabPageCollection tabCollection )
{
_allTabs = new List<TabPage>();
TabOrder = new Dictionary<string, int>();
foreach ( TabPage tab in tabCollection )
{
_allTabs.Add( tab );
}
_tabCollection = tabCollection;
foreach ( int index in Enumerable.Range( 0, tabCollection.Count ) )
{
var tab = tabCollection[index];
TabOrder[tab.Name] = index;
}
}
public void ShowTabPage( string tabText )
{
TabPage page = _allTabs
.Where( t => string.Equals( t.Text, tabText, StringComparison.CurrentCultureIgnoreCase ) )
.First();
int tabPageOrder = TabOrder[page.Name];
if ( !_tabCollection.Contains( page ) )
{
_tabCollection.Insert( tabPageOrder, page );
}
}
public void HideTabPage( string tabText )
{
TabPage page = _allTabs
.Where( t => string.Equals( t.Text, tabText, StringComparison.CurrentCultureIgnoreCase ) )
.First();
int tabPageOrder = TabOrder[page.Name];
if ( _tabCollection.Contains( page ) )
{
_tabCollection.Remove( page );
}
}
}
To use the class, instantiate it in your form load method after initializing your components by passing in the tab control's TabPages property.
public Form1()
{
InitializeComponent();
_tabHelper = new TabPageHelper( tabControl1.TabPages );
}
All of your tab pages should exist on application load (ie: in the Design view) because the class will remember the order of the tab pages when hiding / showing. You can hide or show them selectively throughout your application like this:
_tabHelper.HideTabPage("Settings");
_tabHelper.ShowTabPage("Schedule");
Change your code to
document.write("<td width='74'><button id='button' type='button' onclick='myfunction(\""+ name + "\")'>click</button></td>")
Javascript is flexible:
var arr = {
"fred": {"apple": 2, "orange": 4},
"mary": {}
//etc, etc
};
alert(arr.fred.orange);
alert(arr["fred"]["orange"]);
for (key in arr.fred)
alert(key + ": " + arr.fred[key]);
I think these are not good enough answer(s)... many involve a couple of extra under-the-hood steps. Here's how I did it.
sudo apt-get install jq
...because the JSON output needs to be consumed after you call the API.
#!/bin/bash
server_addr = 'jenkins'
server_port = '8080'
curl -s -k "http://${server_addr}:${server_port}/pluginManager/api/json?depth=1" \
| jq '.plugins[]|{shortName, version,longName,url}' -c | sort \
> plugin-list
echo "dude, here's your list: "
cat plugin-list
Using splice
method is surely the best answer if you need to insert into an array in-place.
However, if you are looking for an immutable function that returns a new updated array instead of mutating the original array on insert, you can use the following function.
function insert(array, index) {
const items = Array.prototype.slice.call(arguments, 2);
return [].concat(array.slice(0, index), items, array.slice(index));
}
const list = ['one', 'two', 'three'];
const list1 = insert(list, 0, 'zero'); // Insert single item
const list2 = insert(list, 3, 'four', 'five', 'six'); // Insert multiple
console.log('Original list: ', list);
console.log('Inserted list1: ', list1);
console.log('Inserted list2: ', list2);

Note: This is a pre-ES2015 way of doing it so it works for both older and newer browsers.
If you're using ES6 then you can try out rest parameters too; see this answer.
Get the current date and time, then just use the time portion of it. Look at the possibilities for formatting a date time string in the MSDN docs.
kennytm's links are dead and he doesn't provide an example so here's how you do substrings:
=MID(text, start_num, char_num)
Let's say cell A1
is Hello
.
=MID(A1, 2, 3)
Would return
ell
Because it says to start at character 2, e
, and to return 3 characters.
In an attempt to spot a change somewhere in a particular column (here in "W", i.e. "23"), I modified Peter Alberts' answer to:
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Target.Column = 23 Then Exit Sub
Application.EnableEvents = False 'to prevent endless loop
On Error GoTo Finalize 'to re-enable the events
MsgBox "You changed a cell in column W, row " & Target.Row
MsgBox "You changed it to: " & Target.Value
Finalize:
Application.EnableEvents = True
End Sub
To expand on the top-voted answer, for reference, if the you want to add more complex items to the array:
@:myArray.push(ClassMember1: "@d.ClassMember1", ClassMember2: "@d.ClassMember2");
etc.
Furthermore, if you want to pass the array as a parameter to your controller, you can stringify it first:
myArray = JSON.stringify({ 'myArray': myArray });
The general idea behind creating "optional arguments" is to first define an intermediate command that scans ahead to detect what characters are coming up next in the token stream and then inserts the relevant macros to process the argument(s) coming up as appropriate. This can be quite tedious (although not difficult) using generic TeX programming. LaTeX's \@ifnextchar
is quite useful for such things.
The best answer for your question is to use the new xparse
package. It is part of the LaTeX3 programming suite and contains extensive features for defining commands with quite arbitrary optional arguments.
In your example you have a \sec
macro that either takes one or two braced arguments. This would be implemented using xparse
with the following:
\documentclass{article} \usepackage{xparse} \begin{document} \DeclareDocumentCommand\sec{ m g }{% {#1% \IfNoValueF {#2} { and #2}% }% } (\sec{Hello}) (\sec{Hello}{Hi}) \end{document}
The argument { m g }
defines the arguments of \sec
; m
means "mandatory argument" and g
is "optional braced argument". \IfNoValue(T)(F)
can then be used to check whether the second argument was indeed present or not. See the documentation for the other types of optional arguments that are allowed.
You must use CSS. Can't be done with PHP.
Adding to Nils Kaspersson's solution, I am resolving for the width of the vertical scrollbar as well. I am using 16px
as an example, which is subtracted from the view-port width. This will avoid the horizontal scrollbar from appearing.
width: calc(100vw - 16px);
left: calc(-1 * (((100vw - 16px) - 100%) / 2));
I created a JsFiddle here based on the answer given by Zachary. It provides a more accessible user interface and also escapes double quotes within strings properly.
var FD = new System.Windows.Forms.OpenFileDialog();
if (FD.ShowDialog() == System.Windows.Forms.DialogResult.OK) {
string fileToOpen = FD.FileName;
System.IO.FileInfo File = new System.IO.FileInfo(FD.FileName);
//OR
System.IO.StreamReader reader = new System.IO.StreamReader(fileToOpen);
//etc
}
export
in sh
and related shells (such as bash
), marks an environment variable to be exported to child-processes, so that the child inherits them.
The shell shall give the export attribute to the variables corresponding to the specified names, which shall cause them to be in the environment of subsequently executed commands. If the name of a variable is followed by = word, then the value of that variable shall be set to word.
Spring exposes the current HttpServletRequest
object (as well as the current HttpSession
object) through a wrapper object of type ServletRequestAttributes
. This wrapper object is bound to ThreadLocal and is obtained by calling the static
method RequestContextHolder.currentRequestAttributes()
.
ServletRequestAttributes
provides the method getRequest()
to get the current request, getSession()
to get the current session and other methods to get the attributes stored in both the scopes. The following code, though a bit ugly, should get you the current request object anywhere in the application:
HttpServletRequest curRequest =
((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
.getRequest();
Note that the RequestContextHolder.currentRequestAttributes()
method returns an interface and needs to be typecasted to ServletRequestAttributes
that implements the interface.

At the end, Node is about Javascript. JS has several way to accomplished something, is the same thing to get an "constructor", the important thing is to return a function.
This way actually you are creating a new function, as we created using JS on Web Browser environment for example.
Personally i prefer the prototype approach, as Sukima suggested on this post: Node.js - use of module.exports as a constructor
I built a laravel package for making statistics : https://github.com/Ifnot/statistics
It is based on eloquent, carbon and indicators so it is really easy to use. It may be usefull for extracting date grouped indicators.
$statistics = Statistics::of(MyModel::query());
$statistics->date('validated_at');
$statistics->interval(Interval::$DAILY, Carbon::createFromFormat('Y-m-d', '2016-01-01'), Carbon::now())
$statistics->indicator('total', function($row) {
return $row->counter;
});
$data = $statistics->make();
echo $data['2016-01-01']->total;
```
You can use android-ripple-background
Start Effect
final RippleBackground rippleBackground=(RippleBackground)findViewById(R.id.content);
ImageView imageView=(ImageView)findViewById(R.id.centerImage);
imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
rippleBackground.startRippleAnimation();
}
});
Stop animation:
rippleBackground.stopRippleAnimation();
For KOTLIN
val rippleBackground = findViewById(R.id.content) as RippleBackground
val imageView: ImageView = findViewById(R.id.centerImage) as ImageView
imageView.setOnClickListener(object : OnClickListener() {
fun onClick(view: View?) {
rippleBackground.startRippleAnimation()
}
})
You can find index by key/values in dictionary
Dictionary<string, string> myDictionary = new Dictionary<string, string>();
myDictionary.Add("a", "x");
myDictionary.Add("b", "y");
int i = Array.IndexOf(myDictionary.Keys.ToArray(), "a");
int j = Array.IndexOf(myDictionary.Values.ToArray(), "y");
Maybe an example from ruby can help:
You can include the mixin Comparable
and define one function "<=>(other)"
, the mixin provides all those functions:
<(other)
>(other)
==(other)
<=(other)
>=(other)
between?(other)
It does this by invoking <=>(other)
and giving back the right result.
"instance <=> other"
returns 0 if both objects are equal, less than 0 if instance
is bigger than other
and more than 0 if other
is bigger.
logical address is address relative to program. It tells how much memory a particular process will take, not tell what will the exact location of the process and this exact location will we generated by using some mapping, and is known as physical address.
Newer versions of Groovy (1.7.2+) offer a JDK extension to more easily traverse over files in a directory, for example:
import static groovy.io.FileType.FILES
def dir = new File(".");
def files = [];
dir.traverse(type: FILES, maxDepth: 0) { files.add(it) };
See also [1] for more examples.

Also you will specify route on action for set route
[HttpGet]
[Route("api/customers/")]
public List<Customer> Get()
{
//gets all customer logic
}
[HttpGet]
[Route("api/customers/currentMonth")]
public List<Customer> GetCustomerByCurrentMonth()
{
//gets some customer
}
[HttpGet]
[Route("api/customers/{id}")]
public Customer GetCustomerById(string id)
{
//gets a single customer by specified id
}
[HttpGet]
[Route("api/customers/customerByUsername/{username}")]
public Customer GetCustomerByUsername(string username)
{
//gets customer by its username
}
Do you have a yellow icon like this [_] at the bottom of the main window? It is a "type-aware highlighting" switch which could be disabled accidentally. You should re-enable it by clicking on the icon.
Below is code that I currently use to pull data from a MS SQL Server 2008 into VBA. You need to make sure you have the proper ADODB reference [VBA Editor->Tools->References] and make sure you have Microsoft ActiveX Data Objects 2.8 Library checked, which is the second from the bottom row that is checked (I'm using Excel 2010 on Windows 7; you might have a slightly different ActiveX version, but it will still begin with Microsoft ActiveX):
Sub Module for Connecting to MS SQL with Remote Host & Username/Password
Sub Download_Standard_BOM()
'Initializes variables
Dim cnn As New ADODB.Connection
Dim rst As New ADODB.Recordset
Dim ConnectionString As String
Dim StrQuery As String
'Setup the connection string for accessing MS SQL database
'Make sure to change:
'1: PASSWORD
'2: USERNAME
'3: REMOTE_IP_ADDRESS
'4: DATABASE
ConnectionString = "Provider=SQLOLEDB.1;Password=PASSWORD;Persist Security Info=True;User ID=USERNAME;Data Source=REMOTE_IP_ADDRESS;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with column collation when possible=False;Initial Catalog=DATABASE"
'Opens connection to the database
cnn.Open ConnectionString
'Timeout error in seconds for executing the entire query; this will run for 15 minutes before VBA timesout, but your database might timeout before this value
cnn.CommandTimeout = 900
'This is your actual MS SQL query that you need to run; you should check this query first using a more robust SQL editor (such as HeidiSQL) to ensure your query is valid
StrQuery = "SELECT TOP 10 * FROM tbl_table"
'Performs the actual query
rst.Open StrQuery, cnn
'Dumps all the results from the StrQuery into cell A2 of the first sheet in the active workbook
Sheets(1).Range("A2").CopyFromRecordset rst
End Sub
I am sure there is a smarter way for doing what you want but this should work:
- name : Test var
hosts : all
gather_facts : no
vars:
myvariable : false
tasks:
- name: param1
set_fact:
myvariable: "{{param1}}"
when: param1 is defined
- name: param2
set_fact:
myvariable: "{{ param2 if not myvariable else myvariable + ',' + param2 }}"
when: param2 is defined
- name: param3
set_fact:
myvariable: "{{ param3 if not myvariable else myvariable + ',' + param3 }}"
when: param3 is defined
- name: default
set_fact:
myvariable: "default"
when: not myvariable
- debug:
var=myvariable
Hope that helps. I am not sure if you can construct variables dynamically and do this in an iterator. But you could also write a small python code or any other language and plug it into ansible
Execute:
ng v
or
ng --version
tell you the current angular cli version number
I've used this query to delete all my records.
http://host/solr/core-name/update?stream.body=%3Cdelete%3E%3Cquery%3E*:*%3C/query%3E%3C/delete%3E&commit=true
As far as I know, Both are same. For cross browser safety you can use window.location
rather than document.location
.
All modern browsers map document.location
to window.location
, but I still prefer window.location
as that's what I've used since I wrote my first web page. it is more consistent.
you can also see document.location === window.location
returns true
, which clarifies that both are same.
When I tried to select the development provisioning profile in Code Signing Identity is would say "profile doesn't match any valid certificate". So when I followed the two step process below it worked:
1) Under "Code Signing Identity" for Development change to "Don't Code Sign".
2) Then Under "Code Signing Identity" for Development you will be able to select your provisioning profile for Development.
Drove me nuts, but stumbled upon the solution.
-XX:PermSize
specifies the initial size that will be allocated during startup of the JVM. If necessary, the JVM will allocate up to -XX:MaxPermSize
.
I had the same issue and realized that removing the parentheses worked. Sometimes having someone else read your code can be useful if you have been the only one working on it for some time.
E.g.
cmd.CommandType = CommandType.Text();
Replace: cmd.CommandType = CommandType.Text;
I assume you have defined custom adapter for your ListView.
If this is the case then you can assign onClickListener
for your button inside the custom adapter's getView()
method.

I was facing the same issue. In my case, I had a dependency of httpclient with an older version while sendgrid required a newer version of httpclient. Just make sure that the version of httpclient is correct in your dependencies and it would work fine.
When you make a POST request, you have to encode the data that forms the body of the request in some way.
HTML forms provide three methods of encoding.
application/x-www-form-urlencoded
(the default)multipart/form-data
text/plain
Work was being done on adding application/json
, but that has been abandoned.
(Other encodings are possible with HTTP requests generated using other means than an HTML form submission. JSON is a common format for use with web services and some still use SOAP.)
The specifics of the formats don't matter to most developers. The important points are:
text/plain
.When you are writing client-side code:
multipart/form-data
when your form includes any <input type="file">
elementsmultipart/form-data
or application/x-www-form-urlencoded
but application/x-www-form-urlencoded
will be more efficientWhen you are writing server-side code:
Most (such as Perl's CGI->param
or the one exposed by PHP's $_POST
superglobal) will take care of the differences for you. Don't bother trying to parse the raw input received by the server.
Sometimes you will find a library that can't handle both formats. Node.js's most popular library for handling form data is body-parser which cannot handle multipart requests (but has documentation which recommends some alternatives which can).
If you are writing (or debugging) a library for parsing or generating the raw data, then you need to start worrying about the format. You might also want to know about it for interest's sake.
application/x-www-form-urlencoded
is more or less the same as a query string on the end of the URL.
multipart/form-data
is significantly more complicated but it allows entire files to be included in the data. An example of the result can be found in the HTML 4 specification.
text/plain
is introduced by HTML 5 and is useful only for debugging — from the spec: They are not reliably interpretable by computer — and I'd argue that the others combined with tools (like the Network Panel in the developer tools of most browsers) are better for that).
I had the same issue on a Mac. It seems to be caused by filesystem ACLs. Try chmod -RN /path/to/repo
to clear the ACLs. After doing this I was able to commit changes. Using the trick to copy the index file, delete the original and move the copy back achieved the same result.
Use sum()
in place of count()
Try below:
SELECT
ccc_news . * ,
SUM(if(ccc_news_comments.id = 'approved', 1, 0)) AS comments
FROM
ccc_news
LEFT JOIN
ccc_news_comments
ON
ccc_news_comments.news_id = ccc_news.news_id
WHERE
`ccc_news`.`category` = 'news_layer2'
AND `ccc_news`.`status` = 'Active'
GROUP BY
ccc_news.news_id
ORDER BY
ccc_news.set_order ASC
LIMIT 20
Making a small tweak to the inside function and using lapply on an index instead of the actual list itself gets this doing what you want
x <- c("yes", "no", "maybe", "no", "no", "yes")
y <- c("red", "blue", "green", "green", "orange")
list.xy <- list(x=x, y=y)
WORD.C <- function(WORDS){
require(wordcloud)
L2 <- lapply(WORDS, function(x) as.data.frame(table(x), stringsAsFactors = FALSE))
# Takes a dataframe and the text you want to display
FUN <- function(X, text){
windows()
wordcloud(X[, 1], X[, 2], min.freq=1)
mtext(text, 3, padj=-4.5, col="red") #what I'm trying that isn't working
}
# Now creates the sequence 1,...,length(L2)
# Loops over that and then create an anonymous function
# to send in the information you want to use.
lapply(seq_along(L2), function(i){FUN(L2[[i]], names(L2)[i])})
# Since you asked about loops
# you could use i in seq_along(L2)
# instead of 1:length(L2) if you wanted to
#for(i in 1:length(L2)){
# FUN(L2[[i]], names(L2)[i])
#}
}
WORD.C(list.xy)
[PrincipalPermission(SecurityAction.Demand, Role = @"BUILTIN\Administrators")]
This will do it without UAC - no need to start a new process. If the running user is member of Admin group as for my case.
I tried with .val()
.text()
.html()
and had some bugs using jQuery to read or set value of a textarea... i endup using native js
$('#message').blur(function() {
if (this.value == '') { this.value = msg_greeting; }
});
How about this?
Assuming you have System.Windows.Forms referenced.
var cbtnToggler = new CheckBox();
cbtnToggler.Appearance = Appearance.Button;
cbtnToggler.TextAlign = ContentAlignment.MiddleCenter;
cbtnToggler.MinimumSize = new Size(75, 25); //To prevent shrinkage!
Hope this helps ;)
the style is:
<style type="text/css">
.topcorner{
position:absolute;
top:0;
right:0;
}
</style>
hope it will work. Thanks
Using ping in C# is achieved by using the method Ping.Send(System.Net.IPAddress)
, which runs a ping request to the provided (valid) IP address or URL and gets a response which is called an Internet Control Message Protocol (ICMP) Packet. The packet contains a header of 20 bytes which contains the response data from the server which received the ping request. The .Net framework System.Net.NetworkInformation
namespace contains a class called PingReply
that has properties designed to translate the ICMP
response and deliver useful information about the pinged server such as:
The following is a simple example using WinForms
to demonstrate how ping works in c#. By providing a valid IP address in textBox1
and clicking button1
, we are creating an instance of the Ping
class, a local variable PingReply
, and a string to store the IP or URL address. We assign PingReply
to the ping Send
method, then we inspect if the request was successful by comparing the status of the reply to the property IPAddress.Success
status. Finally, we extract from PingReply
the information we need to display for the user, which is described above.
using System;
using System.Net.NetworkInformation;
using System.Windows.Forms;
namespace PingTest1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Ping p = new Ping();
PingReply r;
string s;
s = textBox1.Text;
r = p.Send(s);
if (r.Status == IPStatus.Success)
{
lblResult.Text = "Ping to " + s.ToString() + "[" + r.Address.ToString() + "]" + " Successful"
+ " Response delay = " + r.RoundtripTime.ToString() + " ms" + "\n";
}
}
private void textBox1_Validated(object sender, EventArgs e)
{
if (string.IsNullOrWhiteSpace(textBox1.Text) || textBox1.Text == "")
{
MessageBox.Show("Please use valid IP or web address!!");
}
}
}
}
It's not working because the entire for
loop (from the for
to the final closing parenthesis, including the commands between those) is being evaluated when it's encountered, before it begins executing.
In other words, %count%
is replaced with its value 1
before running the loop.
What you need is something like:
setlocal enableextensions enabledelayedexpansion
set /a count = 1
for /f "tokens=*" %%a in (config.properties) do (
set /a count += 1
echo !count!
)
endlocal
Delayed expansion using !
instead of %
will give you the expected behaviour. See also here.
Also keep in mind that setlocal/endlocal
actually limit scope of things changed inside so that they don't leak out. If you want to use count
after the endlocal
, you have to use a "trick" made possible by the very problem you're having:
endlocal && set count=%count%
Let's say count
has become 7 within the inner scope. Because the entire command is interpreted before execution, it effectively becomes:
endlocal && set count=7
Then, when it's executed, the inner scope is closed off, returning count
to it's original value. But, since the setting of count
to seven happens in the outer scope, it's effectively leaking the information you need.
You can string together multiple sub-commands to leak as much information as you need:
endlocal && set count=%count% && set something_else=%something_else%
You can find 64bit installers for a lot of libs here: http://www.lfd.uci.edu/~gohlke/pythonlibs/
Yes there is. It's &
.
&&
will execute command 2 when command 1 is complete providing it didn't fail.
&
will execute regardless.
If a proper encryption method was used, it's not going to be possible to easily retrieve them.
Just reset them with new passwords.
Edit: The string looks like it is using PASSWORD()
:
UPDATE user SET password = PASSWORD("newpassword");
I don't know if this works but I made the variable names

jQuery provides you with:
$(".news").hide();
$(".news").show();
You can then easily show and hide the element(s).
ERR_CACHE_MISS
error solutionyou just need add one line code <uses-permission android:name="android.permission.INTERNET"/>
in your app/src/main/AndroidManifest.xml
file as below screenshots shows.
if you have numbers in list, you can use map
to apply str
to each element:
print ', '.join(map(str, LIST))
^ map
is C code so it's faster than str(i) for i in LIST
As others have pointed out one could just delete all the files in the repo and then check them out. I prefer this method and it can be done with the code below
git ls-files -z | xargs -0 rm
git checkout -- .
or one line
git ls-files -z | xargs -0 rm ; git checkout -- .
I use it all the time and haven't found any down sides yet!
For some further explanation, the -z
appends a null character onto the end of each entry output by ls-files
, and the -0
tells xargs
to delimit the output it was receiving by those null characters.
string number = "123.456789"; // Convert to string
int length = number.Substring(number.IndexOf(".") + 1).Length; // 6
In Windows, first installed Python 3.7 and then Python 2.7. Then, use command prompt:

That's all
As of 2015, you should use CSP2's frame-ancestors
directive for this. This is implemented via an HTTP response header.
e.g.
Content-Security-Policy: frame-ancestors 'none'
Of course, not many browsers support CSP2 yet so it is wise to include the old X-Frame-Options
header:
X-Frame-Options: DENY
I would advise to include both anyway, otherwise your site would continue to be vulnerable to Clickjacking attacks in old browsers, and of course you would get undesirable framing even without malicious intent. Most browsers do update automatically these days, however you still tend to get corporate users being stuck on old versions of Internet Explorer for legacy application compatibility reasons.
That TypeError
only appears when you try to pass int()
None
(which is the only NoneType
value, as far as I know). I would say that your real goal should not be to convert NoneType
to int
or str
, but to figure out where/why you're getting None
instead of a number as expected, and either fix it or handle the None
properly.
For the same issue, I used an easy solution : put a padding-top of 40px on each anchor.
You're using clearInterval incorrectly.
This is the proper use:
Set the timer with
var_name = setInterval(fontChange, 500);
and then
clearInterval(var_name);
I think in this case concat
is what you want:
In [12]:
pd.concat([df,df1], axis=0, ignore_index=True)
Out[12]:
attr_1 attr_2 attr_3 id quantity
0 0 1 NaN 1 20
1 1 1 NaN 2 23
2 1 1 NaN 3 19
3 0 0 NaN 4 19
4 1 NaN 0 5 8
5 0 NaN 1 6 13
6 1 NaN 1 7 20
7 1 NaN 1 8 25
by passing axis=0
here you are stacking the df's on top of each other which I believe is what you want then producing NaN
value where they are absent from their respective dfs.
$("#images").load(location.href+" #images",function(){

use StickyTableHeaders.js for this.

You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like
$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");
You can confirm this by printing out the string to see that it turns out identical to the first case.
Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string
, which would make it look perhaps like this:
$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
mysql_real_escape_string($prefix));
$query = mysql_query($sql);
Note that inside the first argument of sprintf
the percent sign needs to be doubled to end up appearing once in the result.
It doesn't recognize that you have a master branch, but I found a way to get around it. I found out that there's nothing special about a master branch, you can just create another branch and call it master branch and that's what I did.
To create a master branch:
git checkout -b master
And you can work off of that.
I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser
which is doing most of the work. Where he puts req.body.name
, I believe he/she is using body-parser
to get the contents of the name attribute(s) received when the form is submitted.
If you do not want to use Express, use querystring
which is a built-in Node module. See the answers in the link below for an example of how to use querystring
.
It might help to look at this answer, which is very similar to your quest.
You should check out Losswise (https://losswise.com), it has a plugin for Keras that's easier to use than Tensorboard and has some nice extra features. With Losswise you'd just use from losswise.libs import LosswiseKerasCallback
and then callback = LosswiseKerasCallback(tag='my fancy convnet 1')
and you're good to go (see https://docs.losswise.com/#keras-plugin).
With angular 6 spread operator and concat not work. You can resolve it easy:
result.push(...data);
filter_by
uses keyword arguments, whereas filter
allows pythonic filtering arguments like filter(User.name=="john")
Here is another option to see if a cell exists inside a range. In case you have issues with the Intersect solution as I did.
If InStr(range("NamedRange").Address, range("IndividualCell").Address) > 0 Then
'The individual cell exists in the named range
Else
'The individual cell does not exist in the named range
End If
InStr is a VBA function that checks if a string exists within another string.

I think that this code is going to help:
JS:
$('#foo').ready(function () {
$('#loadingMessage').css('display', 'none');
});
$('#foo').load(function () {
$('#loadingMessage').css('display', 'none');
});
HTML:
<iframe src="http://google.com/" id="foo"></iframe>
<div id="loadingMessage">Loading...</div>
CSS:
#loadingMessage {
width: 100%;
height: 100%;
z-index: 1000;
background: #ccc;
top: 0px;
left: 0px;
position: absolute;
}
You need a mechanism which avoids busy-waiting. The old wait/notify
mechanism is fraught with pitfalls so prefer something from the java.util.concurrent
library, for example the CountDownLatch
:
public final CountDownLatch latch = new CountDownLatch(1);
public void run () {
latch.await();
...
}
And at the other side call
yourRunnableObj.latch.countDown();
However, starting a thread to do nothing but wait until it is needed is still not the best way to go. You could also employ an ExecutorService
to which you submit as a task the work which must be done when the condition is met.
Breadth First Search is generally the best approach when the depth of the tree can vary, and you only need to search part of the tree for a solution. For example, finding the shortest path from a starting value to a final value is a good place to use BFS.
Depth First Search is commonly used when you need to search the entire tree. It's easier to implement (using recursion) than BFS, and requires less state: While BFS requires you store the entire 'frontier', DFS only requires you store the list of parent nodes of the current element.
Mine were located here on Ubuntu 18.04 when I installed JavaFX using apt install openjfx
(as noted already by @jewelsea above)
/usr/share/java/openjfx/jre/lib/ext/jfxrt.jar
/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/ext/jfxrt.jar
string = string.replace(/[&\/\\#,+()$~%.'":*?<>{}]/g,'_');
Alternatively, to change all characters except numbers and letters, try:
string = string.replace(/[^a-zA-Z0-9]/g,'_');
In the root directory of the project there is a hidden .git
directory that contains configuration, the repository etc.
To open IIS Manager, click Start, type inetmgr in the Search Programs and Files box, and then press ENTER.
if the IIS Manager doesn't open that means you need to install it.

Actually I think OZ_ may be somewhat correct.
If you have the route '/users/:userId'
and navigate to '/users/'
(note the trailing /), $routeParams
in your controller should be an object containing userId: ""
in 1.1.5. So no the paramater userId
isn't completely ignored, but I think it's the best you're going to get.
You could use cast
(as int) after replacing NaN
with 0
,
data_df = df.withColumn("Plays", df.call_time.cast('float'))
In Java is almost the same:
try

throw e;

Keep an eye on this pull request: https://github.com/docker/docker/pull/7409
Which implements the forthcoming docker exec <container_id> <command>
utility. When this is available it should be possible to e.g. start and stop the ssh service inside a running container.
There is also nsinit
to do this: "nsinit provides a handy way to access a shell inside a running container's namespace", but it looks difficult to get running.

from openpyxl import load_workbook
sheets = load_workbook(excel_file, read_only=True).sheetnames
For a 5MB Excel file I'm working with, load_workbook
without the read_only
flag took 8.24s. With the read_only
flag it only took 39.6 ms. If you still want to use an Excel library and not drop to an xml solution, that's much faster than the methods that parse the whole file.
$.get(str, function(data){
var sary=data.split('|');
document.getElementById("select1").options.length = 0;
document.getElementById("select1").options[0] = new Option('Select a State');
for(i=0;i<sary.length-1;i++){
document.getElementById("select1").options[i+1] = new Option(sary[i]);
document.getElementById("select1").options[i+1].value = sary[i];
}
});
I made this simple Notification wrapper. It works on Chrome, Safari and Firefox.
Probably on Opera, IE and Edge as well but I haven't tested it yet.
Just get the notify.js file from here https://github.com/gravmatt/js-notify and put it into your page.
Get it on Bower
$ bower install js-notify
This is how it works:
notify('title', {
body: 'Notification Text',
icon: 'path/to/image.png',
onclick: function(e) {}, // e -> Notification object
onclose: function(e) {},
ondenied: function(e) {}
});
You have to set the title but the json object as the second argument is optional.
You can use a HTML table:
<table>
<tr>
<td>
<div id="bloc1">your content</div>
</td>
<td>
<div id="bloc2">your content</div>
</td>
</tr>
</table>
This works fine for me Swift 2.x:
imageView.contentMode = .ScaleAspectFill
imageView.clipsToBounds = true;
I'm not sure why there are so many contorted descriptions of doing this. Perhaps because Android Studio (AS) is constantly changing/evolving? Nevertheless, the procedure is this simple.
Assuming you have already installed Gradle in a suitable directory, mean that you probably also defined an environment variable for GRADLE_HOME
, if not define it now, and restart AS.
For my example: GRADLE_HOME=C:\Gradle\gradle-5.2.1
Then fire up AS and navigate to:
File > Settings > Build, Execution, Deployment > Gradle
Now, all you need to do is to select: (o) Use local gradle distribution
.
AS will then tell you it found your local Gradle paths:
Hit Apply
and Ok
and restart AS.
Now all the Gradle data can be found in your HOME directory, usually located here (in this case on Windows):

Axivion Bauhaus Suite is a static analysis tool that works with C# (as well as C, C++ and Java).
It provides the following capabilities:
These features can be run on a one-off basis or as part of a Continuous Integration process. Issues can be highlighted on a per project basis or per developer basis when the system is integrated with a source code control system.
Directory Services/LDAP lookups can be used to serve this purpose. It involves some changes at infrastructure level, but most production environments have such provision

You'll have to re-serve the page with a new title in order for any crawlers to notice the change. Doing it via javascript will only benefit a human reader, crawlers are not going to execute that code.
while
loops check the condition before the loop, do...while
loops check the condition after the loop. This is useful is you want to base the condition on side effects from the loop running or, like other posters said, if you want the loop to run at least once.
I understand where you're coming from, but the do-while
is something that most use rarely, and I've never used myself. You're not doing it wrong.
You're not doing it wrong. That's like saying someone is doing it wrong because they've never used the byte
primitive. It's just not that commonly used.
This works for me:
const from = '2019-01-01';_x000D_
const to = '2019-01-08';_x000D_
_x000D_
Math.abs(_x000D_
moment(from, 'YYYY-MM-DD')_x000D_
.startOf('day')_x000D_
.diff(moment(to, 'YYYY-MM-DD').startOf('day'), 'days')_x000D_
) + 1_x000D_
);
_x000D_
You should convert the string to an enumeration value before comparing.
Enum.TryParse("Retailer", out AccountType accountType);
Then
if (userProfile?.AccountType == accountType)
{
//your code
}
This works for me:
.network-connections-icon {
background-image: url(url);
background-size: 100%;
width: 56px;
height: 56px;
margin: 0 auto;
}
there are two ways to do this in jquery depending what you are looking for..
using jquery you can do
//this will wait for the text assets to be loaded before calling this (the dom.. css.. js)
$(document).ready(function(){...});
//this will wait for all the images and text assets to finish loading before executing
$(window).load(function(){...});
It's documented here.
The sort() method takes optional arguments for controlling the comparisons.
cmp specifies a custom comparison function of two arguments (list items) which should return a negative, zero or positive number depending on whether the first argument is considered smaller than, equal to, or larger than the second argument: cmp=lambda x,y: cmp(x.lower(), y.lower()). The default value is None.
dt
- your data table name
ColumnName
- your columnname i.e id
DataView view = new DataView(dt);
DataTable distinctValues = new DataTable();
distinctValues = view.ToTable(true, ColumnName);
Use this
$("input[name='nameOfYourRadioButton']").attr("checked", false);
I have tried in Python2.7.17
Some of the fellow folks already answered. However I have tried to call getattr(obj, 'set_value') and this didn't execute the set_value method, So i changed to getattr(obj, 'set_value')() --> This helps to invoke the same.
Example Code:
Example 1:
class GETATT_VERIFY():
name = "siva"
def __init__(self):
print "Ok"
def set_value(self):
self.value = "myself"
print "oooh"
obj = GETATT_VERIFY()
print getattr(GETATT_VERIFY, 'name')
getattr(obj, 'set_value')()
print obj.value
I am a little late but for Python 3.9.1 this worked for me and removed the -b prefix:
print(outputCode.decode())
Now NgForm supports two methods: .reset() vs .resetForm() the latter also changes the submit state of the form to false reverting form and its controls to initial states.
You may try like this:
import java.applet.Applet;
import java.awt.*;
public class Rect1 extends Applet {
public void paint (Graphics g) {
g.drawRect (x, y, width, height); //can use either of the two//
g.fillRect (x, y, width, height);
g.setColor(color);
}
}
where x is x co-ordinate y is y cordinate color=the color you want to use eg Color.blue
if you want to use rectangle object you could do it like this:
import java.applet.Applet;
import java.awt.*;
public class Rect1 extends Applet {
public void paint (Graphics g) {
Rectangle r = new Rectangle(arg,arg1,arg2,arg3);
g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());
g.setColor(color);
}
}
If you have no FIRST/FIRST conflicts and no FIRST/FOLLOW conflicts, your grammar is LL(1).
An example of a FIRST/FIRST conflict:
S -> Xb | Yc
X -> a
Y -> a
By seeing only the first input symbol a, you cannot know whether to apply the production S -> Xb or S -> Yc, because a is in the FIRST set of both X and Y.
An example of a FIRST/FOLLOW conflict:
S -> AB
A -> fe | epsilon
B -> fg
By seeing only the first input symbol f, you cannot decide whether to apply the production A -> fe or A -> epsilon, because f is in both the FIRST set of A and the FOLLOW set of A (A can be parsed as epsilon and B as f).
Notice that if you have no epsilon-productions you cannot have a FIRST/FOLLOW conflict.
The solutions given here fail on either directories or symlinks (or both). On Linux, you can test files, directories and symlinks with:
if [[ -f "$file" && -x $(realpath "$file") ]]; then .... fi
On OS X, you should be able to install coreutils with homebrew and use grealpath
.
isexec
functionYou can define a function for convenience:
isexec() {
if [[ -f "$1" && -x $(realpath "$1") ]]; then
true;
else
false;
fi;
}
Or simply
isexec() { [[ -f "$1" && -x $(realpath "$1") ]]; }
Then you can test using:
if `isexec "$file"`; then ... fi
just share what i've been used, and works nicely

A possible solution here might be to tell the compiler to include the header without it being mentioned in the source files. IN GCC there are these options:
-include file
Process file as if "#include "file"" appeared as the first line of
the primary source file. However, the first directory searched for
file is the preprocessor's working directory instead of the
directory containing the main source file. If not found there, it
is searched for in the remainder of the "#include "..."" search
chain as normal.
If multiple -include options are given, the files are included in
the order they appear on the command line.
-imacros file
Exactly like -include, except that any output produced by scanning
file is thrown away. Macros it defines remain defined. This
allows you to acquire all the macros from a header without also
processing its declarations.
All files specified by -imacros are processed before all files
specified by -include.
Microsoft's compiler has the /FI (forced include) option.
This feature can be handy for some common header, like platform configuration. The Linux kernel's Makefile uses -include
for this.

LPCWSTR
stands for "Long Pointer to Constant Wide String". The W stands for Wide and means that the string is stored in a 2 byte character vs. the normal char
. Common for any C/C++ code that has to deal with non-ASCII only strings.=
To get a normal C literal string to assign to a LPCWSTR
, you need to prefix it with L
LPCWSTR a = L"TestWindow";
There is HTML and URI encodings. &
is &
encoded in HTML while %26
is &
in URI encoding.
So before URI encoding your string you might want to HTML decode and then URI encode it :)
var div = document.createElement('div');
div.innerHTML = '&AndOtherHTMLEncodedStuff';
var htmlDecoded = div.firstChild.nodeValue;
var urlEncoded = encodeURIComponent(htmlDecoded);
result %26AndOtherHTMLEncodedStuff
Hope this saves you some time
You normally use a tool like pip
to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.
For this to work, you do need to install the wheel
package:
pip install wheel
You can then tell pip
to install the project (and it'll download the wheel if available), or the wheel file directly:
pip install project_name # discover, download and install
pip install wheel_file.whl # directly install the wheel
The wheel
module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:
python -m wheel install wheel_file.whl
Also see the wheel
project documentation.
Maybe you just want to print the table headers on the console. This is my code: (for each table)
// ------------------ show header ----------------
char sqlite_stmt_showHeader[1000];
snprintf(sqlite_stmt_showHeader, 1000, "%s%s", "SELECT * FROM ", TABLE_NAME_STRING UTF8String]);
sqlite3_stmt* statement_showHeader;
sqlite3_prepare_v2(DATABASE, sqlite_stmt_showHeader, -1, &statement_showHeader, NULL);
int headerColumnSize = sqlite3_column_count(statement_showHeader);
NSString* headerRow = @"|";
for (int j = 0; j < headerColumnSize; j++) {
NSString* headerColumnContent = [[NSString alloc] initWithUTF8String:(const char*)sqlite3_column_name(statement_showHeader, j)];
headerRow = [[NSString alloc] initWithFormat:@"%@ %@ |", headerRow, headerColumnContent];
}
NSLog(@"%@", headerRow);
sqlite3_finalize(statement_showHeader);
// ---------------- show header end ---------------------
PowerShell is a good choice ;) It is very easy to enumerate files in given directory, read them and process.
The script could look like this:
Get-ChildItem C:\Projects *.config -recurse |
Foreach-Object {
$c = ($_ | Get-Content)
$c = $c -replace '<add key="Environment" value="Dev"/>','<add key="Environment" value="Demo"/>'
[IO.File]::WriteAllText($_.FullName, ($c -join "`r`n"))
}
I split the code to more lines to be readable for you.
Note that you could use Set-Content instead of [IO.File]::WriteAllText
, but it adds new line at the end. With WriteAllText
you can avoid it.
Otherwise the code could look like this: $c | Set-Content $_.FullName
.
For those of you using Spring, you can simply reference any classpath-resource using the classpath-protocol. So in case of the wsdlLocation, this becomes:
<wsdlLocation>classpath:META-INF/webservice.wsdl</wsdlLocation>
Note that is not standard Java behavior. See also: http://docs.spring.io/spring/docs/current/spring-framework-reference/html/resources.html
I couldn't figure out how to use the API using the first Google results. Fortunately a thread somewhere pointed me to this link: http://access.mvps.org/access/api/api0049.htm
Which works nicely. :)
Based on my Comment here is one way to get what you want done:
Start byt selecting any cell in your range and Press Ctrl + T
This will give you this pop up:
make sure the Where is your table text is correct and click ok you will now have:
Now If you add a column header in D it will automatically be added to the table all the way to the last row:
Now If you enter a formula into this column:
After you enter it, the formula will be auto filled all the way to last row:
Now if you add a new row at the next row under your table:
Once entered it will be resized to the width of your table and all columns with formulas will be added also:
Hope this solves your problem!
You can use any
:
print any(df.column == 07311954)
True #true if it contains the number, false otherwise
If you rather want to see how many times '07311954' occurs in a column you can use:
df.column[df.column == 07311954].count()
Anti-virus software may also be interfering with output flushing. In my case, Kaspersky Anti-Virus 2013 was holding data chunks before sending it to the browser, even though I was using an accepted solution.

I don't care if the page reloads or displays the results immediately;
Good!
Note: If you don't want to refresh the page see "Ok... but how do I Use Ajax anyway?" below.
I just want to have a button on my website make a PHP file run.
That can be done with a form with a single button:
<form action="">
<input type="submit" value="my button"/>
</form>
That's it.
Pretty much. Also note that there are cases where ajax is really the way to go.
That depends on what you want. In general terms you only need ajax when you want to avoid realoading the page. Still you have said that you don't care about that.
If I can write the code inside HTML just fine, why can't I just reference the file for it in there or make a simple call for it in Javascript?
Because the PHP code is not in the HTML just fine
. That's an illusion created by the way most server side scripting languages works (including PHP, JSP, and ASP). That code only exists on the server, and it is no reachable form the client (the browser) without a remote call of some sort.
You can see evidence of this if you ask your browser to show the source code of the page. There you will not see the PHP code, that is because the PHP code is not send to the client, therefore it cannot be executed from the client. That's why you need to do a remote call to be able to have the client trigger the execution of PHP code.
If you don't use a form (as shown above) you can do that remote call from JavaScript with a little thing called Ajax. You may also want to consider if what you want to do in PHP can be done directly in JavaScript.
Use a form to do the call. You can have it to direct the user to a particlar file:
<form action="myphpfile.php">
<input type="submit" value="click on me!">
</form>
The user will end up in the page myphpfile.php
. To make it work for the current page, set action to an empty string (which is what I did in the example I gave you early).
I just want to link it to a PHP file that will create the permanent blog post on the server so that when I reload the page, the post is still there.
You want to make an operation on the server, you should make your form have the fields you need (even if type="hidden"
and use POST
):
<form action="" method="POST">
<input type="text" value="default value, you can edit it" name="myfield">
<input type="submit" value = "post">
</form>
What do I need to know about it to call a PHP file that will create a text file on a button press?
see: How to write into a file in PHP.
I'm glad you ask... Since you are a newb begginer, I'll give you a little template you can follow:
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST')
{
//Ok we got a POST, probably from a FORM, read from $_POST.
var_dump($_PSOT); //Use this to see what info we got!
}
else
{
//You could assume you got a GET
var_dump($_GET); //Use this to see what info we got!
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta char-set="utf-8">
<title>Page title</title>
</head>
<body>
<form action="" method="POST">
<input type="text" value="default value, you can edit it" name="myfield">
<input type="submit" value = "post">
</form>
</body>
</html>
Note: you can remove var_dump
, it is just for debugging purposes.
I know the next stage, you will be asking how to:
There is a single answer for that: Sessions.
I'll give a more extensive template for Post-Redirect-Get
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST')
{
var_dump($_PSOT);
//Do stuff...
//Write results to session
session_start();
$_SESSION['stuff'] = $something;
//You can store stuff such as the user ID, so you can remeember him.
//redirect:
header('Location: ', true, 303);
//The redirection will cause the browser to request with GET
//The results of the operation are in the session variable
//It has empty location because we are redirecting to the same page
//Otherwise use `header('Location: anotherpage.php', true, 303);`
exit();
}
else
{
//You could assume you got a GET
var_dump($_GET); //Use this to see what info we got!
//Get stuff from session
session_start();
if (array_key_exists('stuff', $_SESSION))
{
$something = $_SESSION['stuff'];
//we got stuff
//later use present the results of the operation to the user.
}
//clear stuff from session:
unset($_SESSION['stuff']);
//set headers
header('Content-Type: text/html; charset=utf-8');
//This header is telling the browser what are we sending.
//And it says we are sending HTML in UTF-8 encoding
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta char-set="utf-8">
<title>Page title</title>
</head>
<body>
<?php if (isset($something)){ echo '<span>'.$something.'</span>'}?>;
<form action="" method="POST">
<input type="text" value="default value, you can edit it" name="myfield">
<input type="submit" value = "post">
</form>
</body>
</html>
Please look at php.net for any function call you don't recognize. Also - if you don't have already - get a good tutorial on HTML5.
Also, use UTF-8 because UTF-8!
Notes:
I'm making a simple blog site for myself and I've got the code for the site and the javascript that can take the post I write in a textarea and display it immediately.
If are you using a CMS (Codepress, Joomla, Drupal... etc)? That make put some contraints on how you got to do things.
Also, if you are using a framework, you should look at their documentation or ask at their forum/mailing list/discussion page/contact or try to ask the authors.
Well... Ajax is made easy by some JavaScript libraries. Since you are a begginer, I'll recomend jQuery.
So, let's send something to the server via Ajax with jQuery, I'll use $.post instead of $.ajax for this example.
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST')
{
var_dump($_PSOT);
header('Location: ', true, 303);
exit();
}
else
{
var_dump($_GET);
header('Content-Type: text/html; charset=utf-8');
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta char-set="utf-8">
<title>Page title</title>
<script>
function ajaxmagic()
{
$.post( //call the server
"test.php", //At this url
{
field: "value",
name: "John"
} //And send this data to it
).done( //And when it's done
function(data)
{
$('#fromAjax').html(data); //Update here with the response
}
);
}
</script>
</head>
<body>
<input type="button" value = "use ajax", onclick="ajaxmagic()">
<span id="fromAjax"></span>
</body>
</html>
The above code will send a POST request to the page test.php
.
Note: You can mix sessions
with ajax
and stuff if you want.
... for these or any other, please make another questions. That's too much for this one.

This is a just a nice idea. that, you can Add class in body, and hide/show table while there is no data in table. This works perfect for me. You can design custom NO Record Found error message when there is no record in table, you can add class "no-record", and when there is 1 or more than one record, you can remove class and show datatable
Here is jQuery code.
$('#default_table').DataTable({
// your stuff here
"fnFooterCallback": function (nRow, aaData, iStart, iEnd, aiDisplay) {
if (aiDisplay.length > 0) {
$('body').removeClass('no-record');
}
else {
$('body').addClass('no-record');
}
}
});
Here is CSS
.no-record #default_table{display:none;}
That's not padding, it's the shadow around the button in its background drawable. Create your own background and it will disappear.
Try the following script:
Exec sp_msforeachtable 'SET QUOTED_IDENTIFIER ON; ALTER INDEX ALL ON ? REBUILD'
GO
Also
I prefer(After a long search) to use the following script, it contains @fillfactor
determines how much percentage of the space on each leaf-level page is filled with data.
DECLARE @TableName VARCHAR(255)
DECLARE @sql NVARCHAR(500)
DECLARE @fillfactor INT
SET @fillfactor = 80
DECLARE TableCursor CURSOR FOR
SELECT QUOTENAME(OBJECT_SCHEMA_NAME([object_id]))+'.' + QUOTENAME(name) AS TableName
FROM sys.tables
OPEN TableCursor
FETCH NEXT FROM TableCursor INTO @TableName
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sql = 'ALTER INDEX ALL ON ' + @TableName + ' REBUILD WITH (FILLFACTOR = ' + CONVERT(VARCHAR(3),@fillfactor) + ')'
EXEC (@sql)
FETCH NEXT FROM TableCursor INTO @TableName
END
CLOSE TableCursor
DEALLOCATE TableCursor

I caught this error a few days ago.
IN my case it was because I was using a Transaction on a Singleton.
.Net does not work well with Singleton as stated above.
My solution was this:
public class DbHelper : DbHelperCore
{
public DbHelper()
{
Connection = null;
Transaction = null;
}
public static DbHelper instance
{
get
{
if (HttpContext.Current is null)
return new DbHelper();
else if (HttpContext.Current.Items["dbh"] == null)
HttpContext.Current.Items["dbh"] = new DbHelper();
return (DbHelper)HttpContext.Current.Items["dbh"];
}
}
public override void BeginTransaction()
{
Connection = new SqlConnection(Entity.Connection.getCon);
if (Connection.State == System.Data.ConnectionState.Closed)
Connection.Open();
Transaction = Connection.BeginTransaction();
}
}
I used HttpContext.Current.Items for my instance. This class DbHelper and DbHelperCore is my own class

Simple way is to use curl
from command-line, for example:
DATA="foo=bar&baz=qux"
curl --data "$DATA" --request POST --header "Content-Type:application/x-www-form-urlencoded" http://example.com/api/callback | python -m json.tool
or here is example how to send raw POST request using Bash shell (JSON request):
exec 3<> /dev/tcp/example.com/80
DATA='{"email": "[email protected]"}'
LEN=$(printf "$DATA" | wc -c)
cat >&3 << EOF
POST /api/retrieveInfo HTTP/1.1
Host: example.com
User-Agent: Bash
Accept: */*
Content-Type:application/json
Content-Length: $LEN
Connection: close
$DATA
EOF
# Read response.
while read line <&3; do
echo $line
done
You can also use like this, to delete particular value when both the columns having 2 or many of same column name.
DELETE project , create_test FROM project INNER JOIN create_test
WHERE project.project_name='Trail' and create_test.project_name ='Trail' and project.uid= create_test.uid = '1';
Well, I had great trouble figuring out the non-blocking commands... But finally, I managed to rework the "Cookbook/Matplotlib/Animations - Animating selected plot elements" example, so it works with threads (and passes data between threads either via global variables, or through a multiprocess Pipe
) on Python 2.6.5 on Ubuntu 10.04.
The script can be found here: Animating_selected_plot_elements-thread.py - otherwise pasted below (with fewer comments) for reference:

line, = ax.plot(x, nx.sin(x), animated=True)
# save the clean slate background -- everything but the animated line
# is drawn and saved in the pixel buffer background
background = canvas.copy_from_bbox(ax.bbox)

Edit: This now requires C++17 and concepts. (As of 9/12/16, only g++ 6.0+ is sufficient.)
The template deduction is a lot more accurate because of it, though, so it's worth the effort of getting a newer compiler. I've not yet found a function that requires explicit template arguments.
It also now takes any appropriate callable object (and is still statically typesafe!!!).
It also now includes an optional green threading priority thread pool using the same API. This class is POSIX only, though. It uses the ucontext_t
API for userspace task switching.
I created a simple library for this. An example of usage is given below. (I'm answering this because it was one of the things I found before I decided it was necessary to write it myself.)
bool is_prime(int n){
// Determine if n is prime.
}
int main(){
thread_pool pool(8); // 8 threads
list<future<bool>> results;
for(int n = 2;n < 10000;n++){
// Submit a job to the pool.
results.emplace_back(pool.async(is_prime, n));
}
int n = 2;
for(auto i = results.begin();i != results.end();i++, n++){
// i is an iterator pointing to a future representing the result of is_prime(n)
cout << n << " ";
bool prime = i->get(); // Wait for the task is_prime(n) to finish and get the result.
if(prime)
cout << "is prime";
else
cout << "is not prime";
cout << endl;
}
}
You can pass async
any function with any (or void) return value and any (or no) arguments and it will return a corresponding std::future
. To get the result (or just wait until a task has completed) you call get()
on the future.

Found a solution with pop
and map
d = {'a': 'valueA', 'b': 'valueB', 'c': 'valueC', 'd': 'valueD'}
keys = ['a', 'b', 'c']
list(map(d.pop, keys))
print(d)
The output of this:

I have answered this question so late just because I think it will help in the future if anyone searches the same. And this might help.
Update
The above code will throw an error if a key does not exist in the dict.
DICTIONARY = {'a': 'valueA', 'b': 'valueB', 'c': 'valueC', 'd': 'valueD'}
keys = ['a', 'l', 'c']
def remove_keys(key):
try:
DICTIONARY.pop(key, None)

@Grantismo provides a great explanation on the overall. If you wish to know who people are actually doing this things i suggest you to take a look at how google did for the Google IO App of 2014 (it's always worth taking a deep look at the source code of these apps that they release. There's a lot to learn from there).
Here's a blog post about it: http://android-developers.blogspot.com.br/2014/09/conference-data-sync-gcm-google-io.html
Essentially, on the application side: GCM for signalling, Sync Adapter for data fetching and talking properly with Content Provider that will make things persistent (yeah, it isolates the DB from direct access from other parts of the app).
Also, if you wish to take a look at the 2015's code: https://github.com/google/iosched
For external url you have to use "http://www.yahoo.com" as the redirect url.
This is explained in the redirect: prefix of Spring reference documentation.
redirect:/myapp/some/resource
will redirect relative to the current Servlet context, while a name such as
will redirect to an absolute URL
This may not be the answer you are looking for, but may help others whose jquery is not working properly, or working sometimes and not at other times.
This could be because your jquery has not yet loaded and you have started to interact with the page. Either put jquery on top in head (probably not a very great idea) or use a loader or spinner to stop the user from interacting with the page until the entire jquery has loaded.
Here you go: Here you go: Create a System Restore Point. Log on under an admin account. Delete the folder C:\SomeUser. Move the folder c:\Users\SomeUser so that it becomes c:\SomeUser. Open the registry editor. Navigate to HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList. Search for "ProfileImagePath" until you find the one that points at c:\Users\SomeUser. Modify it so that it points at c:\SomeUser. Use System Restore in case things go wrong.
Offering another potential solution to this error.
If you have a frontend application that makes API calls to the backend, make sure you reference the domain name that the certificate has been issued to.
e.g.
https://example.com/api/etc
and not
https://123.4.5.6/api/etc
In my case, I was making API calls to a secure server with a certificate, but using the IP instead of the domain name. This threw a Failed to load resource: net::ERR_INSECURE_RESPONSE
.
If you don't give any position to parent then by default it takes static
. If you want to understand that difference refer to this example
Example 1::
#mainall
{
background-color:red;
height:150px;
overflow:scroll
}
Here parent class has no position so element is placed according to body.
Example 2::
#mainall
{
position:relative;
background-color:red;
height:150px;
overflow:scroll
}
In this example parent has relative position hence element are positioned absolute inside relative parent.

What you can do is use nltk to tokenize words and then store all of the words in a list, here's what I did. If you don't know nltk; it stands for natural language toolkit and is used to process natural language. Here's some resource if you wanna get started [http://www.nltk.org/book/]
import nltk
from nltk.tokenize import word_tokenize
file = open("abc.txt",newline='')
result = file.read()
words = word_tokenize(result)
for i in words:
print(i)
The output will be this:
09807754
18
n
03
aristocrat
0
blue_blood
0
patrician
Following on from jpw it might be good to encapsulate his solution in a small subroutine to save on having lots of lines of code:
Private Sub CommandButton1_Click()
Dim i As Integer
Dim a As Integer
a = 15
For i = 11 To 32
If Worksheets(1).Cells(i, 3) <> "" Then
call copValuesAndFormat(i,3,a,15)
call copValuesAndFormat(i,5,a,17)
call copValuesAndFormat(i,6,a,18)
call copValuesAndFormat(i,7,a,19)
call copValuesAndFormat(i,8,a,20)
call copValuesAndFormat(i,9,a,21)
a = a + 1
End If
Next i
end sub
sub copValuesAndFormat(x1 as integer, y1 as integer, x2 as integer, y2 as integer)
Worksheets(1).Cells(x1, y1).Copy
Worksheets(2).Cells(x2, y2).PasteSpecial Paste:=xlPasteFormats
Worksheets(2).Cells(x2, y2).PasteSpecial Paste:=xlPasteValues
end sub
(I do not have Excel in current location so please excuse bugs as not tested)
Like this... I used it to read Chinese characters...
Dim reader as StreamReader = My.Computer.FileSystem.OpenTextFileReader(filetoimport.Text)
Dim a as String
Do
a = reader.ReadLine
'
' Code here
'
Loop Until a Is Nothing
reader.Close()
This is the Swift version of David's Objective-C answer. You use the global queue to run things in the background and the main queue to update the UI.
DispatchQueue.global(qos: .background).async {
// Background Thread
DispatchQueue.main.async {
// Run UI Updates
}
}
The simplest supported solution is to either use margin

Or use a second container around the element that has this margin applied. This will somewhat have the effect of padding: 0px auto
if it did exist.

If you are generating a heap of commands to be run, then call that script from a terminal, you can try the following.
sftp login@host < /path/to/command/list
You will then be asked to enter your password (as per normal) however all the commands in the script run after that.
This is clearly not a completely automated option that can be used in a cron
job, but it can be used from a terminal.
I have the similar problem and fixed it by temporarily disabling my antivirus(Kaspersky Free 18.0.0.405). This AV has HTTPS interception module that automatically self-sign all certificates it finds in HTTPS responses.
Wget from Cygwin does not know anything about AV root certificate, so when it finds that website's certificate was signed with non trust certificate it prints that error.
To fix this permanently without disabling AV you should copy the AV root certificate from Windows certificate store to /etc/pki/ca-trust/source/anchors
as .pem file(base64 encoding) and run update-ca-trust
I want to add the important hint that converting a project like this can have side effects which are noticeable when you have a larger project. This is due the fact that Intellij Idea (2017) takes some important settings only from the pom.xml then which can lead to some confusion, following sections are affected at least:
All these points need review and adjusting but after this it works like charm.
Further more unfortunately there is no sufficient pom.xml template created, I have added an example which might help to solve most problems.

Actually they are the same. LEFT OUTER JOIN
is same as LEFT JOIN
and RIGHT OUTER JOIN
is same as RIGHT JOIN
. It is more informative way to compare from INNER Join
.

If you want to format a datetime
object in a specific format that is different from the standard format, it's best to explicitly specify that format:
>>> datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
'2011-11-03 18:21:26'
See the documentation of datetime.strftime()
for an explanation of the %
directives.
Works for me:
public class BackupService

private readonly string _connectionString;
private readonly string _backupFolderFullPath;

{
_connectionString = connectionString;
_backupFolderFullPath = backupFolderFullPath;
}
public void BackupAllUserDatabases()
{
foreach (string databaseName in GetAllUserDatabases())
{
BackupDatabase(databaseName);
}
}
public void BackupDatabase(string databaseName)
{

using (var connection = new SqlConnection(_connectionString))
{
var query = String.Format("BACKUP DATABASE [{0}] TO DISK='{1}'", databaseName, filePath);
using (var command = new SqlCommand(query, connection))
{
connection.Open();
command.ExecuteNonQuery();
}

Again, AJAX is async. So the showMsg function will be called only after success response from the server.. and the form submit event will not wait until AJAX success.
Move the e.preventDefault();
as first line in the click handler.
$("form").submit(function (e) {
e.preventDefault(); // this will prevent from submitting the form.
...
See below code,
I want it to be allowed HasJobInProgress == False
$(document).ready(function () {
$("form").submit(function (e) {
e.preventDefault(); //prevent default form submit
$.ajax({
url: '@Url.Action("HasJobInProgress", "ClientChoices")/',
data: { id: '@Model.ClientId' },
success: function (data) {
showMsg(data);
},
cache: false
});
});
});
$("#cancelButton").click(function () {
window.location = '@Url.Action("list", "default", new { clientId = Model.ClientId })';
});
$("[type=text]").focus(function () {
$(this).select();
});
function showMsg(hasCurrentJob) {
if (hasCurrentJob == "True") {
alert("The current clients has a job in progress. No changes can be saved until current job completes");
return false;
} else {
$("form").unbind('submit').submit();
}
}
Had the same problem in Ubuntu 14 using XAMPP. Here's what I did which worked..
replace
$cfg['Servers'][1]['relation'] = 'pma__relation';
$cfg['Servers'][1]['userconfig'] = 'pma__userconfig';
$cfg['Servers'][1]['table_info'] = 'pma__table_info';
...
to
$cfg['Servers'][1]['pma__relation'] = 'pma__relation';
$cfg['Servers'][1]['pma__userconfig'] = 'pma__userconfig';
$cfg['Servers'][1]['pma__table_info'] = 'pma__table_info';
...
basically add pma__ prefix to the left side similar to the right.
Hope this helps.
You may find this a little more intuitive. It only requires one function call to array_splice
:
$original = array( 'a', 'b', 'c', 'd', 'e' );
$inserted = array( 'x' ); // not necessarily an array, see manual quote
array_splice( $original, 3, 0, $inserted ); // splice in at position 3
// $original is now a b c x d e
If replacement is just one element it is not necessary to put array() around it, unless the element is an array itself, an object or NULL.
window.scrollTo(0,1);
this will help you but this javascript is may not work in all browsers
Look at this online backend.
They offer push notifications, social integration, data storage, and the ability to add rich custom logic to your app’s backend with Cloud Code.
I'm not sure that I understand the statement. Hope this helps. If you want to operate with only one instance of this form you should prevent Form.Dispose call on user close. In order to do this, you can handle child form's Closing event.
private void ChildForm_FormClosing(object sender, FormClosingEventArgs e)
{
this.Hide();
e.Cancel = true;
}
And then you don't need to create new instances of frm
. Just call Show method on the instance.
You can check Form.Visible property to check if the form open at the moment.
private ChildForm form = new ChildForm();
private void ReopenChildForm()
{
if(form.Visible)
{
form.Hide();
}
//Update form information
form.Show();
}
Actually, I still don't understand why don't you just update the data on the form.
copy the image that you want to show in android app and paste in drawable folder. given below code
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"

Try https://github.com/tmpvar/jsdom - you give it some HTML and it gives you a DOM.
Yes. Click on the object (textbox, shape, etc.) to select the object and in the Drawing Tools | Format tab, click on Selection Pane in the Arrange group. From there, you'll see names of objects - you can double click (or press F2) on any name and rename it. By deselecting it, it becomes renamed. You can also get to this from the Home tab -> Drawing group -> Arrange drop-down -> Selection pane or by pressing ALT + F10.

You probably do not need to be making lists and appending them to make your array. You can likely just do it all at once, which is faster since you can use numpy to do your loops instead of doing them yourself in pure python.
To answer your question, as others have said, you cannot access a nested list with two indices like you did. You can if you convert mean_data
to an array before not after you try to slice it:
R = np.array(mean_data)[:,0]
instead of
R = np.array(mean_data[:,0])
But, assuming mean_data has a shape nx3
, instead of
R = np.array(mean_data)[:,0]
P = np.array(mean_data)[:,1]
Z = np.array(mean_data)[:,2]
You can simply do
A = np.array(mean_data).mean(axis=0)
which averages over the 0
th axis and returns a length-n
array
But to my original point, I will make up some data to try to illustrate how you can do this without building any lists one item at a time:
Combining two byte[]
using iTextSharp up to version 5.x:
internal static MemoryStream mergePdfs(byte[] pdf1, byte[] pdf2)
{
MemoryStream outStream = new MemoryStream();
using (Document document = new Document())
using (PdfCopy copy = new PdfCopy(document, outStream))
{
document.Open();
copy.AddDocument(new PdfReader(pdf1));
copy.AddDocument(new PdfReader(pdf2));
}
return outStream;
}
Instead of the byte[]
's it's possible to pass also Stream

What you're trying to accomplish is called Reverse DNS lookup.
socket.gethostbyaddr("IP")

However, for the timeout part I have read about people running into problems with this. I would check out PyDNS or this solution for more advanced treatment.
My below code solve this issue, but i suggest First of all you need to understand what causing this issue and try the solution which you can find by changing code
I can give another way to solve this issue but better solution is to check your coding structure and try to analyse what makes this happen,if you do not find any solution then you can go with this code below
try{
Start:
///Put your file access code here
}catch (Exception ex)
{
//by anyway you need to handle this error with below code
if (ex.Message.StartsWith("The process cannot access the file"))
{
//Wait for 5 seconds to free that file and then start execution again
Thread.Sleep(5000);
goto Start;
}
}
That's not possible using the built-in Array.prototype.map
. However, you could use a simple for
-loop instead, if you do not intend to map
any values:
var hasValueLessThanTen = false;
for (var i = 0; i < myArray.length; i++) {
if (myArray[i] < 10) {
hasValueLessThanTen = true;
break;
}
}
Or, as suggested by @RobW
, use Array.prototype.some
to test if there exists at least one element that is less than 10. It will stop looping when some element that matches your function is found:
var hasValueLessThanTen = myArray.some(function (val) {
return val < 10;
});
As per latest Ansible Version 2.5, to check if a variable is defined and depending upon this if you want to run any task, use undefined
keyword.
tasks:
- shell: echo "I've got '{{ foo }}' and am not afraid to use it!"
when: foo is defined
- fail: msg="Bailing out. this play requires 'bar'"
when: bar is undefined
It's a function annotation.
In more detail, Python 2.x has docstrings, which allow you to attach a metadata string to various types of object. This is amazingly handy, so Python 3 extends the feature by allowing you to attach metadata to functions describing their parameters and return values.
There's no preconceived use case, but the PEP suggests several. One very handy one is to allow you to annotate parameters with their expected types; it would then be easy to write a decorator that verifies the annotations or coerces the arguments to the right type. Another is to allow parameter-specific documentation instead of encoding it into the docstring.

For selenium, an alert is the one which raised using javascript e.g.
javascript:alert();
There is one basic check to verify whether your alert is actually a javascript alert or just a div-based box for displaying some message. If its a javascript alert, you wont be able to see it on screen while running the selenium script.
If you are able to see it, then you need to get the locator of the ok button of the alert and use selenium.click(locator) to dismiss the alert. Can help you better if you can provide more context:

The content inside strings in Golang can be compared using ==
operator. If the results are not as expected there may be some hidden characters like \n
, \r
, spaces, etc. So as a general rule of thumb, try removing those using functions provided by strings
package in golang.
For Instance, spaces can be removed using strings.TrimSpace
function. You can also define a custom function to remove any character you need. strings.TrimFunc
function can give you more power.
Not sure if this violates some good practice coding rule but I usually come out with this one:
if(typeof __t == 'undefined')
__t = 0;
clearTimeout(__t);
__t = setTimeout(callback, 1000);
This prevent the need to declare the timer out of the function.
EDIT: this also don't declare a new variable at each invocation, but always recycle the same.
Hope this helps.
\d
is called a character class and will match digits. It is equal to [0-9]
.
+
matches 1 or more occurrences of the character before.
So \d+
means match 1 or more digits.

in swift 5
textField.attributedPlaceholder = NSAttributedString(string: "placeholder text", attributes: [NSAttributedString.Key.foregroundColor : UIColor.black])
Just because you declare your struct B
inside class A
does not mean that an instance of class A
automatically has the properties of struct B
as members, nor does it mean that it automatically has an instance of struct B
as a member.
There is no true relation between the two classes (A
and B
), besides scoping.
struct A {
struct B {
int v;
};
B inner_object;
};

main (int argc, char *argv[]) {
A object;
object.inner_object.v = 123;

Came here looking something similar to that, but with a CASE WHEN, and ended using the where like this: WHERE (CASE WHEN COLUMN1=COLUMN2 THEN '1' ELSE '0' END) = 0
maybe you could use DATEDIFF
in the WHERE
directly.
Something like:
SELECT logcount, logUserID, maxlogtm
FROM statslogsummary
WHERE (DATEDIFF(day, maxlogtm, GETDATE())) > 120
Above example is also correct, but i provide simple example:
var fs = require("fs");
var sampleObject = {
name: 'pankaj',
member: 'stack',
type: {
x: 11,
y: 22
}
};
fs.writeFile("./object.json", JSON.stringify(sampleObject, null, 4), (err) => {
if (err) {
console.error(err);
return;
};
console.log("File has been created");
});
I have found the EXECUTE command as suggested here T-SQL - function with default parameters to work well. With this approach there is no 'DEFAULT' needed when calling the function, you just omit the parameter as you would with a stored procedure.
The accepted answer by Francisco Spaeth works and is easy to follow. However, I think that method of building JSON sucks! This was really driven home for me as I converted some Python to Java where I could use dictionaries and nested lists, etc. to build JSON with ridiculously greater ease.
What I really don't like is having to instantiate separate objects (and generally even name them) to build up these nestings. If you have a lot of objects or data to deal with, or your use is more abstract, that is a real pain!
I tried getting around some of that by attempting to clear and reuse temp json objects and lists, but that didn't work for me because all the puts and gets, etc. in these Java objects work by reference not value. So, I'd end up with JSON objects containing a bunch of screwy data after still having some ugly (albeit differently styled) code.
So, here's what I came up with to clean this up. It could use further development, but this should help serve as a base for those of you looking for more reasonable JSON building code:
import java.util.AbstractMap.SimpleEntry;
import java.util.ArrayList;
import java.util.List;
import org.json.simple.JSONObject;
// create and initialize an object
public static JSONObject buildObject( final SimpleEntry... entries ) {
JSONObject object = new JSONObject();
for( SimpleEntry e : entries ) object.put( e.getKey(), e.getValue() );
return object;
}
// nest a list of objects inside another
public static void putObjects( final JSONObject parentObject, final String key,
final JSONObject... objects ) {
List objectList = new ArrayList<JSONObject>();
for( JSONObject o : objects ) objectList.add( o );
parentObject.put( key, objectList );
}
Implementation example:
JSONObject jsonRequest = new JSONObject();
putObjects( jsonRequest, "parent1Key",
buildObject(
new SimpleEntry( "child1Key1", "someValue" )
, new SimpleEntry( "child1Key2", "someValue" )
)
, buildObject(
new SimpleEntry( "child2Key1", "someValue" )
, new SimpleEntry( "child2Key2", "someValue" )
)
);
