I was getting this error while trying to show DatePicker
from Fragment
.
I changed
val datePickerDialog = DatePickerDialog(activity!!.applicationContext, ...)
to
val datePickerDialog = DatePickerDialog(requireContext(), ...)
and it worked just fine.
If there is a root layout like RelativeLayout or LinearLayout which contain all of the adapter item's component in CardView, you have to set background attribute in that root layout. like:
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="122dp"
android:layout_marginBottom="6dp"
android:layout_marginLeft="6dp"
android:layout_marginRight="6dp"
card_view:cardCornerRadius="4dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/touch_bg"/>
</android.support.v7.widget.CardView>
For Select2 Jquery problem
The problem is due to the HTML5 validation cannot focus a hidden invalid element. I came across this issue when I was dealing with jQuery Select2 plugin.
Solution You could inject an event listener on and 'invalid' event of every element of a form so that you can manipulate just before the HTML5 validate event.
$('form select').each(function(i){
this.addEventListener('invalid', function(e){
var _s2Id = 's2id_'+e.target.id; //s2 autosuggest html ul li element id
var _posS2 = $('#'+_s2Id).position();
//get the current position of respective select2
$('#'+_s2Id+' ul').addClass('_invalid'); //add this class with border:1px solid red;
//this will reposition the hidden select2 just behind the actual select2 autosuggest field with z-index = -1
$('#'+e.target.id).attr('style','display:block !important;position:absolute;z-index:-1;top:'+(_posS2.top-$('#'+_s2Id).outerHeight()-24)+'px;left:'+(_posS2.left-($('#'+_s2Id).width()/2))+'px;');
/*
//Adjust the left and top position accordingly
*/
//remove invalid class after 3 seconds
setTimeout(function(){
$('#'+_s2Id+' ul').removeClass('_invalid');
},3000);
return true;
}, false);
});
Well, it's fairly simple to do.
On the window resize event handler, calculate how much the window has grown/shrunk, and use that fraction to adjust 1) Height, 2) Width, 3) Canvas.Top, 4) Canvas.Left properties of all the child controls inside the canvas.
Here's the code:
private void window1_SizeChanged(object sender, SizeChangedEventArgs e)
{
myCanvas.Width = e.NewSize.Width;
myCanvas.Height = e.NewSize.Height;
double xChange = 1, yChange = 1;
if (e.PreviousSize.Width != 0)
xChange = (e.NewSize.Width/e.PreviousSize.Width);
if (e.PreviousSize.Height != 0)
yChange = (e.NewSize.Height / e.PreviousSize.Height);
foreach (FrameworkElement fe in myCanvas.Children )
{
/*because I didn't want to resize the grid I'm having inside the canvas in this particular instance. (doing that from xaml) */
if (fe is Grid == false)
{
fe.Height = fe.ActualHeight * yChange;
fe.Width = fe.ActualWidth * xChange;
Canvas.SetTop(fe, Canvas.GetTop(fe) * yChange);
Canvas.SetLeft(fe, Canvas.GetLeft(fe) * xChange);
}
}
}
Try setting the checkbox's opacity to 0. If you want the checkbox to be out of flow try position:absolute
and offset the checkbox by a large number.
HTML
<label class="checkbox"><input type="checkbox" value="valueofcheckbox" checked="checked" style="opacity:0; position:absolute; left:9999px;">Option Text</label>
Here's a relatively easy method to do this. Throw a GridView into your layout, setting the stretch mode to stretch the column widths, set the spacing to 0 (or whatever you want), and set the number of columns to 2:
res/layout/main.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<GridView
android:id="@+id/gridview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:verticalSpacing="0dp"
android:horizontalSpacing="0dp"
android:stretchMode="columnWidth"
android:numColumns="2"/>
</FrameLayout>
Make a custom ImageView
that maintains its aspect ratio:
src/com/example/graphicstest/SquareImageView.java
public class SquareImageView extends ImageView {
public SquareImageView(Context context) {
super(context);
}
public SquareImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public SquareImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
setMeasuredDimension(getMeasuredWidth(), getMeasuredWidth()); //Snap to width
}
}
Make a layout for a grid item using this SquareImageView and set the scaleType to centerCrop:
res/layout/grid_item.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.example.graphicstest.SquareImageView
android:id="@+id/picture"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"/>
<TextView
android:id="@+id/text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="15dp"
android:paddingBottom="15dp"
android:layout_gravity="bottom"
android:textColor="@android:color/white"
android:background="#55000000"/>
</FrameLayout>
Now make some sort of adapter for your GridView
:
src/com/example/graphicstest/MyAdapter.java
private final class MyAdapter extends BaseAdapter {
private final List<Item> mItems = new ArrayList<Item>();
private final LayoutInflater mInflater;
public MyAdapter(Context context) {
mInflater = LayoutInflater.from(context);
mItems.add(new Item("Red", R.drawable.red));
mItems.add(new Item("Magenta", R.drawable.magenta));
mItems.add(new Item("Dark Gray", R.drawable.dark_gray));
mItems.add(new Item("Gray", R.drawable.gray));
mItems.add(new Item("Green", R.drawable.green));
mItems.add(new Item("Cyan", R.drawable.cyan));
}
@Override
public int getCount() {
return mItems.size();
}
@Override
public Item getItem(int i) {
return mItems.get(i);
}
@Override
public long getItemId(int i) {
return mItems.get(i).drawableId;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
View v = view;
ImageView picture;
TextView name;
if (v == null) {
v = mInflater.inflate(R.layout.grid_item, viewGroup, false);
v.setTag(R.id.picture, v.findViewById(R.id.picture));
v.setTag(R.id.text, v.findViewById(R.id.text));
}
picture = (ImageView) v.getTag(R.id.picture);
name = (TextView) v.getTag(R.id.text);
Item item = getItem(i);
picture.setImageResource(item.drawableId);
name.setText(item.name);
return v;
}
private static class Item {
public final String name;
public final int drawableId;
Item(String name, int drawableId) {
this.name = name;
this.drawableId = drawableId;
}
}
}
Set that adapter to your GridView
:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
GridView gridView = (GridView)findViewById(R.id.gridview);
gridView.setAdapter(new MyAdapter(this));
}
And enjoy the results:
I know this question is 4-5 years old, but still, this might be useful:
Sometimes, if you have only a few elements that "exit the screen", the list might not scroll. That's because the operating system doesn't view it as actually exceeding the screen.
I'm saying this because I ran into this problem today - I only had 2 or 3 elements that were exceeding the screen limits, and my list wasn't scrollable. And it was a real mystery. As soon as I added a few more, it started to scroll.
So you have to make sure it's not a design problem at first, like the list appearing to go beyond the borders of the screen but in reality, "it doesn't", and adjust its dimensions and margin values and see if it's starting to "become scrollable". It did, for me.
There is a trick for this. All you have to do is to use RelativeLayout
instead of LinearLayout
as the main container. It's important to have android:layout_gravity="fill_horizontal"
set for it. That should do it.
android:editable="false"
should work, but it is deprecated, you should be using android:inputType="none"
instead.
Alternatively, if you want to do it in the code you could do this :
EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setEnabled(false);
This is also a viable alternative :
EditText mEdit = (EditText) findViewById(R.id.yourid);
mEdit.setKeyListener(null);
If you're going to make your EditText
non-editable, may I suggest using the TextView
widget instead of the EditText
, since using a EditText seems kind of pointless in that case.
EDIT: Altered some information since I've found that android:editable
is deprecated, and you should use android:inputType="none"
, but there is a bug about it on android code; So please check this.
I tried the top answer by David Merriman and it also didn't work in my case. But I found the suggestion to run this code delayed here and it works like a charm.
val editText = view.findViewById<View>(R.id.settings_input_text)
editText.postDelayed({
editText.requestFocus()
val imm = context.getSystemService(INPUT_METHOD_SERVICE) as? InputMethodManager
imm?.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT)
}, 100)
For future readers!
Starting from material components android 1.2.0-alpha01, you have slider
component
ex:
<com.google.android.material.slider.Slider
android:id="@+id/slider"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:valueFrom="20f"
android:valueTo="70f"
android:stepSize="10" />
UPDATE 2
@Override
protected void onResume() {
super.onResume();
mUserNameEdit.requestFocus();
mUserNameEdit.postDelayed(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
InputMethodManager keyboard = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
keyboard.showSoftInput(mUserNameEdit, 0);
}
},200); //use 300 to make it run when coming back from lock screen
}
I tried very hard and found out a solution ... whenever a new activity starts then keyboard cant open but we can use Runnable in onResume and it is working fine so please try this code and check...
UPDATE 1
add this line in your AppLogin.java
mUserNameEdit.requestFocus();
and this line in your AppList.java
listview.requestFocus()'
after this check your application if it is not working then add this line in your AndroidManifest.xml
file
<activity android:name=".AppLogin" android:configChanges="keyboardHidden|orientation"></activity>
<activity android:name=".AppList" android:configChanges="keyboard|orientation"></activity>
ORIGINAL ANSWER
InputMethodManager imm = (InputMethodManager)this.getSystemService(Service.INPUT_METHOD_SERVICE);
for hide keyboard
imm.hideSoftInputFromWindow(ed.getWindowToken(), 0);
for show keyboard
imm.showSoftInput(ed, 0);
for focus on EditText
ed.requestFocus();
where ed is EditText
If you don't care about HTML5 validation (maybe you are validating in JS or on the server), you could try adding "novalidate" to the form or the input elements.
public void actionPerformed(ActionEvent arg0)
{
if (arg0.getSource()==clearButton)
{
enterText.setText(null);
enterText.grabFocus(); //Places flashing cursor on text box
}
}
I know this question is asked long ago, but who ever is stuck for now can solve this by adding this line into your ListView
android:nestedScrollingEnabled="true"
For Example -
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:nestedScrollingEnabled="true" />
Old question, but I came across it when I had a similar issue and thought I'd share what I ended up doing.
The view that gained focus was different each time so I used the very generic:
View current = getCurrentFocus();
if (current != null) current.clearFocus();
If you only want to change the progress bar color, you can simply use a color filter in your Activity's onCreate() method:
ProgressBar progressbar = (ProgressBar) findViewById(R.id.progressbar);
int color = 0xFF00FF00;
progressbar.getIndeterminateDrawable().setColorFilter(color, PorterDuff.Mode.SRC_IN);
progressbar.getProgressDrawable().setColorFilter(color, PorterDuff.Mode.SRC_IN);
Idea from here.
You only need to do this for pre-lollipop versions. On Lollipop you can use the colorAccent style attribute.
Similar to the answer of @ShimonDoodkin this is what I did in a fragment.
https://stackoverflow.com/a/29229865/2413303
passwordInput.postDelayed(new ShowKeyboard(), 300); //250 sometimes doesn't run if returning from LockScreen
Where ShowKeyboard
is
private class ShowKeyboard implements Runnable {
@Override
public void run() {
passwordInput.setFocusableInTouchMode(true);
passwordInput.requestFocus();
getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
((InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE)).showSoftInput(passwordInput, 0);
}
}
After a successful input, I also make sure I hide the keyboard
getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
((InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE))
.hideSoftInputFromWindow(getView().getWindowToken(), 0);
Try this
btn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
btn.setBackgroundResource(R.drawable.icon);
}
});
Starting with Android 4.x, Android team fixed a potential
security problem by adding a new function adjustWindowParamsLw()
in which it
will add FLAG_NOT_FOCUSABLE
, FLAG_NOT_TOUCHABLE
and remove FLAG_WATCH_OUTSIDE_TOUCH
flags for TYPE_SYSTEM_OVERLAY
windows.
That is, a TYPE_SYSTEM_OVERLAY
window won't receive any touch event on ICS platform and, of course, to use TYPE_SYSTEM_OVERLAY
is not a workable solution for ICS and future devices.
You only have to set the ViewGroup with the attribute:
android:focusableInTouchMode="true"
The ViewGroup is the layout that includes every child view.
<TextView
android:ellipsize="marquee"
android:singleLine="true"
.../>
must call in code
textView.setSelected(true);
you can just get the pos
that you get from the onItemClick
and do:
listView.setItemChecked(pos, false);
that's the best way i know of
If the list is dynamic and contains focusable widgets, then the right option is to use RecyclerView instead of ListView IMO.
The workarounds that set adjustPan
, FOCUS_AFTER_DESCENDANTS
, or manually remember focused position, are indeed just workarounds. They have corner cases (scrolling + soft keyboard issues, caret changing position in EditText). They don't change the fact that ListView creates/destroys views en masse during notifyDataSetChanged
.
With RecyclerView, you notify about individual inserts, updates, and deletes. The focused view is not being recreated so no issues with form controls losing focus. As an added bonus, RecyclerView animates the list item insertions and removals.
Here's an example from official docs on how to get started with RecyclerView
: Developer guide - Create a List with RecyclerView
I have dynamically used to get this . I have a LinearLayout and within this used ScrollView as a child. Then i take again LinearLayout and add what ever View u want to this LinearLayout and then this LinearLayout add to ScrollView and finally add this ScrollView to LinearLayout. Then u can get scroll in ur ScrollView and nothing will left to visible.
LinearLayout(Parent)--ScrollView(child of LinerLayout) -- LinearLayout(child of ScrollView)-- add here textView, Buttons , spinner etc whatever u want . Then add this LinearLyout to ScrollView. Bcoz only one CHILD for ScrollView applicable and last add this ScrollView to LinearLyout.If defined area is exceed from Screen size then u will get a Scroll within ScrollView.
I Know it's late but this may help, this is an example how I write custom adapter class for different click actions
public class CustomAdapter extends BaseAdapter {
TextView title;
Button button1,button2;
public long getItemId(int position) {
return position;
}
public int getCount() {
return mAlBasicItemsnav.size(); // size of your list array
}
public Object getItem(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = getLayoutInflater().inflate(R.layout.listnavsub_layout, null, false); // use sublayout which you want to inflate in your each list item
}
title = (TextView) convertView.findViewById(R.id.textViewnav); // see you have to find id by using convertView.findViewById
title.setText(mAlBasicItemsnav.get(position));
button1=(Button) convertView.findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//your click action
// if you have different click action at different positions then
if(position==0)
{
//click action of 1st list item on button click
}
if(position==1)
{
//click action of 2st list item on button click
}
});
// similarly for button 2
button2=(Button) convertView.findViewById(R.id.button2);
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//your click action
});
return convertView;
}
}
Late but simplest answer, just add this in parent layout of the XML.
android:focusable="true"
android:focusableInTouchMode="true"
Upvote if it helped you ! Happy Coding :)
The problem is that once the IsUserNameFocused is set to true, it will never be false. This solves it by handling the GotFocus and LostFocus for the FrameworkElement.
I was having trouble with the source code formatting so here is a link
try FocusManager.SetFocusedElement
FocusManager.SetFocusedElement(parentElement, txtCompanyID)
Here's my implementation, which behaves exactly as item in list (at least on 2.3)
res/layout/list_video_footer.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="@+id/list_video_footer"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@android:drawable/list_selector_background"
android:clickable="true"
android:gravity="center"
android:minHeight="98px"
android:text="@string/more"
android:textColor="@color/bright_text_dark_focused"
android:textSize="18dp"
android:textStyle="bold" />
</FrameLayout>
res/color/bright_text_dark_focused.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true" android:color="#444"/>
<item android:state_focused="true" android:color="#444"/>
<item android:state_pressed="true" android:color="#444"/>
<item android:color="#ccc"/>
</selector>
What container are you adding the UserControl to? Generally when you add controls to a Grid, they will stretch to fill the available space (unless their row/column is constrained to a certain width).
i also faced similar issue. I could able to solve this by setting JAVA_HOME in Environment variable in windows. Setting JAVA_HOME in batch file is not working in this case.
Try:
UPDATE Dispatch_Post
SET isSync = 1
WHERE ChallanNo
IN (SELECT TOP 1000 ChallanNo FROM dbo.Dispatch_Post ORDER BY
CreatedDate DESC)
The Separator
you are using is a UI component. You would be better using a simple String sep = ", "
.
You need to use reflection to get the method to start with, then "construct" it by supplying type arguments with MakeGenericMethod:
MethodInfo method = typeof(Sample).GetMethod(nameof(Sample.GenericMethod));
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);
For a static method, pass null
as the first argument to Invoke
. That's nothing to do with generic methods - it's just normal reflection.
As noted, a lot of this is simpler as of C# 4 using dynamic
- if you can use type inference, of course. It doesn't help in cases where type inference isn't available, such as the exact example in the question.
You can also done this by using group by clause
SELECT purchases.address_id, purchases.* FROM "purchases"
WHERE "purchases"."product_id" = 1 GROUP BY address_id,
purchases.purchased_at ORDER purchases.purchased_at DESC
I was having this issue when I was using Application Verifier to verify my win service. Even after I closed App Ver my service was blocked from deletion. Only removing the service from App Ver resolved the issue and service was deleted right away. Looks like some process still using your service after you tried to delete one.
eval()
can not handle the list object
tf.reset_default_graph()
a = tf.Variable(0.2, name="a")
b = tf.Variable(0.3, name="b")
z = tf.constant(0.0, name="z0")
for i in range(100):
z = a * tf.cos(z + i) + z * tf.sin(b - i)
grad = tf.gradients(z, [a, b])
init = tf.global_variables_initializer()
with tf.Session() as sess:
init.run()
print("z:", z.eval())
print("grad", grad.eval())
but Session.run()
can
print("grad", sess.run(grad))
correct me if I am wrong
On Lubuntu, I just tried apt-get purge ruby* and as well as removing ruby, it looks like this command tried to remove various things to do with GRUB, which is a bit worrying for next time I want to reboot my computer. I can't yet say if any damage has really been done.
I encountered with this issue spending couple of hours, however solved it in different ways. You can see, I have just created an assets folder outside application folder. Finally I linked my style sheet in the page header section. Folder structure are below images.
Before action this you should include url helper file either in your controller class method/__constructor files or by in autoload.php file. Also change $config['base_url'] = 'http://yoursiteurl';
in the following file application/config/config.php
If you include it in controller class method/__constructor then it look like
public function __construct()
{
$this->load->helper('url');
}
or If you load in autoload file then it would looks like
$autoload['helper'] = array('url');
Finally, add your stylesheet file. You can link a style sheet by different ways, include it in your inside section
-><link rel="stylesheet" href="<?php echo base_url();?>assets/css/style.css" type="text/css" />
-> or
<?php
$main = array(
'href' => 'assets/css/style.css',
'rel' => 'stylesheet',
'type' => 'text/css',
'title' => 'main stylesheet',
'media' => 'all',
'index_page' => true
);
echo link_tag($main); ?>
-> or
finally I get more reliable code cleaner concept. Just create a config file, named styles.php in you application/config/styles.php folder. Then add some links in styles.php file looks like below
<?php
$config['style'] = array(
'main' => array(
'href' => 'assets/css/style.css',
'rel' => 'stylesheet',
'type' => 'text/css',
'title' => 'main stylesheet',
'media' => 'all',
'index_page' => true
)
);
?>
call/add this config to your controller class method looks like below
$this->config->load('styles');
$data['style'] = $this->config->config['style'];
Pass this data in your header template looks like below.
$this->load->view('templates/header', $data);
And finally add or link your css file looks like below.
<?php echo link_tag($style['main']); ?>
You can use file_get_contents
to issue any http POST/PUT/DELETE/OPTIONS/HEAD
methods, in addition to the GET
method as the function name suggests.
Here's some advice from someone with an environment where we have folders containing tens of millions of files.
To answer your question more directly: If you're looking at 100K entries, no worries. Go knock yourself out. If you're looking at tens of millions of entries, then either:
a) Make plans to sub-divide them into sub-folders (e.g., lets say you have 100M files. It's better to store them in 1000 folders so that you only have 100,000 files per folder than to store them into 1 big folder. This will create 1000 folder indices instead of a single big one that's more likely to hit the max # of fragments limit or
b) Make plans to run contig.exe on a regular basis to keep your big folder's index defragmented.
Read below only if you're bored.
The actual limit isn't on the # of fragment, but on the number of records of the data segment that stores the pointers to the fragment.
So what you have is a data segment that stores pointers to the fragments of the directory data. The directory data stores information about the sub-directories & sub-files that the directory supposedly stored. Actually, a directory doesn't "store" anything. It's just a tracking and presentation feature that presents the illusion of hierarchy to the user since the storage medium itself is linear.
My jQuery plugin works for me:
Usage:
$('form input[type="text"]').autoFit({
});
Source code of jquery.auto-fit.js
:
;
(function ($) {
var methods = {
init: function (options) {
var settings = $.extend(true, {}, $.fn.autoFit.defaults, options);
var $this = $(this);
$this.keydown(methods.fit);
methods.fit.call(this, null);
return $this;
},
fit: function (event) {
var $this = $(this);
var val = $this.val().replace(' ', '-');
var fontSize = $this.css('font-size');
var padding = $this.outerWidth() - $this.width();
var contentWidth = $('<span style="font-size: ' + fontSize + '; padding: 0 ' + padding / 2 + 'px; display: inline-block; position: absolute; visibility: hidden;">' + val + '</span>').insertAfter($this).outerWidth();
$this.width((contentWidth + padding) + 'px');
return $this;
}
};
$.fn.autoFit = function (options) {
if (typeof options == 'string' && methods[options] && typeof methods[options] === 'function') {
return methods[options].apply(this, Array.prototype.slice.call(arguments, 1));
} else if (typeof options === 'object' || !options) {
// Default to 'init'
return this.each(function (i, element) {
methods.init.apply(this, [options]);
});
} else {
$.error('Method ' + options + ' does not exist on jquery.auto-fit.');
return null;
}
};
$.fn.autoFit.defaults = {};
})(this['jQuery']);
The problem with other answers is they either use a global, which can be overwritten when several functions are in a call chain, or echo
which means your function cannot output diagnostic info (you will forget your function does this and the "result", i.e. return value, will contain more info than your caller expects, leading to weird bug), or eval
which is way too heavy and hacky.
The proper way to do this is to put the top level stuff in a function and use a local
with bash's dynamic scoping rule. Example:
func1()
{
ret_val=hi
}
func2()
{
ret_val=bye
}
func3()
{
local ret_val=nothing
echo $ret_val
func1
echo $ret_val
func2
echo $ret_val
}
func3
This outputs
nothing
hi
bye
Dynamic scoping means that ret_val
points to a different object depending on the caller! This is different from lexical scoping, which is what most programming languages use. This is actually a documented feature, just easy to miss, and not very well explained, here is the documentation for it (emphasis is mine):
Variables local to the function may be declared with the local builtin. These variables are visible only to the function and the commands it invokes.
For someone with a C/C++/Python/Java/C#/javascript background, this is probably the biggest hurdle: functions in bash are not functions, they are commands, and behave as such: they can output to stdout
/stderr
, they can pipe in/out, they can return an exit code. Basically there is no difference between defining a command in a script and creating an executable that can be called from the command line.
So instead of writing your script like this:
top-level code
bunch of functions
more top-level code
write it like this:
# define your main, containing all top-level code
main()
bunch of functions
# call main
main
where main()
declares ret_val
as local
and all other functions return values via ret_val
.
See also the following Unix & Linux question: Scope of Local Variables in Shell Functions.
Another, perhaps even better solution depending on situation, is the one posted by ya.teck which uses local -n
.
You can pass in any CMake variable on the command line, or edit cached variables using ccmake/cmake-gui. On the command line,
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr . && make all install
Would configure the project, build all targets and install to the /usr prefix. The type (PATH) is not strictly necessary, but would cause the Qt based cmake-gui to present the directory chooser dialog.
Some minor additions as comments make it clear that providing a simple equivalence is not enough for some. Best practice would be to use an external build directory, i.e. not the source directly. Also to use more generic CMake syntax abstracting the generator.
mkdir build && cd build && cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr .. && cmake --build . --target install --config Release
You can see it gets quite a bit longer, and isn't directly equivalent anymore, but is closer to best practices in a fairly concise form... The --config is only used by multi-configuration generators (i.e. MSVC), ignored by others.
Here's a solution that uses more modern syntax and is less verbose than the ones already provided:
const canvas = document.querySelector("canvas");
const ctx = canvas.getContext("2d");
const video = document.querySelector("video");
video.addEventListener('play', () => {
function step() {
ctx.drawImage(video, 0, 0, canvas.width, canvas.height)
requestAnimationFrame(step)
}
requestAnimationFrame(step);
})

Like the other answers said, sp_reset_connection
indicates that connection pool is being reused. Be aware of one particular consequence!
Jimmy Mays' MSDN Blog said:
sp_reset_connection does NOT reset the transaction isolation level to the server default from the previous connection's setting.
UPDATE: Starting with SQL 2014, for client drivers with TDS version 7.3 or higher, the transaction isolation levels will be reset back to the default.
ref: SQL Server: Isolation level leaks across pooled connections
Here is some additional information:
What does sp_reset_connection do?
Data access API's layers like ODBC, OLE-DB and System.Data.SqlClient all call the (internal) stored procedure sp_reset_connection when re-using a connection from a connection pool. It does this to reset the state of the connection before it gets re-used, however nowhere is documented what things get reset. This article tries to document the parts of the connection that get reset.
sp_reset_connection resets the following aspects of a connection:
All error states and numbers (like @@error)
Stops all EC's (execution contexts) that are child threads of a parent EC executing a parallel query
Waits for any outstanding I/O operations that is outstanding
Frees any held buffers on the server by the connection
Unlocks any buffer resources that are used by the connection
Releases all allocated memory owned by the connection
Clears any work or temporary tables that are created by the connection
Kills all global cursors owned by the connection
Closes any open SQL-XML handles that are open
Deletes any open SQL-XML related work tables
Closes all system tables
Closes all user tables
Drops all temporary objects
Aborts open transactions
Defects from a distributed transaction when enlisted
Decrements the reference count for users in current database which releases shared database locks
Frees acquired locks
Releases any acquired handles
Resets all SET options to the default values
Resets the @@rowcount value
Resets the @@identity value
Resets any session level trace options using dbcc traceon()
Resets CONTEXT_INFO to
NULL
in SQL Server 2005 and newer [ not part of the original article ]sp_reset_connection will NOT reset:
Security context, which is why connection pooling matches connections based on the exact connection string
Application roles entered using sp_setapprole, since application roles could not be reverted at all prior to SQL Server 2005. Starting in SQL Server 2005, app roles can be reverted, but only with additional information that is not part of the session. Before closing the connection, application roles need to be manually reverted via sp_unsetapprole using a "cookie" value that is captured when
sp_setapprole
is executed.
Note: I am including the list here as I do not want it to be lost in the ever transient web.
Node.JS is a server-side technology, not a browser technology. Thus, Node-specific calls, like require()
, do not work in the browser.
See browserify or webpack if you wish to serve browser-specific modules from Node.
After reading cURL documentation on the options you used, it looks like the private key of certificate is not in the same file. If it is in different file, you need to mention it using --key file and supply passphrase.
So, please make sure that either cert.pem has private key (along with the certificate) or supply it using --key option.
Also, this documentation mentions that Note that this option assumes a "certificate" file that is the private key and the private certificate concatenated!
How they are concatenated? It is quite easy. Put them one after another in the same file.
You can get more help on this here.
I believe this might help you.

If you're looking for an address (IPv4) of the specific interface say wlan0 then try this code which uses getifaddrs():
#include <arpa/inet.h>
#include <sys/socket.h>
#include <netdb.h>
#include <ifaddrs.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
int main(int argc, char *argv[])
{
struct ifaddrs *ifaddr, *ifa;
int family, s;
char host[NI_MAXHOST];
if (getifaddrs(&ifaddr) == -1)
{
perror("getifaddrs");
exit(EXIT_FAILURE);
}
for (ifa = ifaddr; ifa != NULL; ifa = ifa->ifa_next)
{
if (ifa->ifa_addr == NULL)
continue;
s=getnameinfo(ifa->ifa_addr,sizeof(struct sockaddr_in),host, NI_MAXHOST, NULL, 0, NI_NUMERICHOST);
if((strcmp(ifa->ifa_name,"wlan0")==0)&&(ifa->ifa_addr->sa_family==AF_INET))
{
if (s != 0)
{
printf("getnameinfo() failed: %s\n", gai_strerror(s));
exit(EXIT_FAILURE);
}
printf("\tInterface : <%s>\n",ifa->ifa_name );
printf("\t Address : <%s>\n", host);
}
}
freeifaddrs(ifaddr);
exit(EXIT_SUCCESS);
}
You can replace wlan0 with eth0 for ethernet and lo for local loopback.

I discovered quite by accident (I was working with images at the time) that the box-shadow, border-radius and transitions work quite well with the bog-standard audio tag player. I have this working in Chrome, FF and Opera.
audio:hover, audio:focus, audio:active
{
-webkit-box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
-moz-box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
-webkit-transform: scale(1.05);
-moz-transform: scale(1.05);
transform: scale(1.05);
}
with:-
audio
{
-webkit-transition:all 0.5s linear;
-moz-transition:all 0.5s linear;
-o-transition:all 0.5s linear;
transition:all 0.5s linear;
-moz-box-shadow: 2px 2px 4px 0px #006773;
-webkit-box-shadow: 2px 2px 4px 0px #006773;
box-shadow: 2px 2px 4px 0px #006773;
-moz-border-radius:7px 7px 7px 7px ;
-webkit-border-radius:7px 7px 7px 7px ;
border-radius:7px 7px 7px 7px ;
}
I grant you it only "tarts it up a bit", but it makes them a sight more exciting than what's already there, and without doing MAJOR fannying about in JS.
NOT available in IE, unfortunately (not yet supporting the transition bit), but it seems to degrade nicely.
One way to skip this is by creating a specific app password variable.
And you can use that generated password
to access or to push commits from your terminal, when using a Google Account to sign in into Bitbucket.

}
Or

The aim of having the kernel support different ones is that you can try them out without a reboot; you can then run test workloads through the sytsem, measure performance, and then make that the standard one for your app.
On modern server-grade hardware, only the noop one appears to be at all useful. The others seem slower in my tests.
Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.
First the actual accounts:
LocalService account (preferred)
A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.
NT AUTHORITY\LocalService
HKEY_USERS\S-1-5-19
)
Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).
NT AUTHORITY\NetworkService
MANGO$
) to remote serversHKEY_USERS\S-1-5-20
)NETWORK SERVICE
into the Select User or Group dialog
LocalSystem account (dangerous, don't use!)
Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)
.\LocalSystem
(can also use LocalSystem
or ComputerName\LocalSystem
)HKCU
represents the default user)MANGO$
) to remote servers
Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService
can still access the internet.
The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).
It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.
In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).
In Windows Server 2003 you cannot run a scheduled task as
NT_AUTHORITY\LocalService
(aka the Local Service account), or NT AUTHORITY\NetworkService
(aka the Network Service account). That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.
A service running as NetworkService
presents the machine credentials on the network. This means that if your computer was called mango
, it would present as the machine account MANGO$

You need change url from https://android.googleapis.com/gcm/send to https://fcm.googleapis.com/fcm/send and change your app library too. this tutorial can help you https://firebase.google.com/docs/cloud-messaging/server#implementing-http-connection-server-protocol
This is very classic case: If you end up having to check for any data provided by the http instance then consider moving that code under the BeginRequest
event.
void Application_BeginRequest(Object source, EventArgs e)
This is the right place to check for http headers, query string and etc...
Application_Start
is for the settings that apply for the application entire run time, such as routing, filters, logging and so on.
Please, don't apply any workarounds such as static .ctor or switching to the Classic mode unless there's no way to move the code from the Start
to BeginRequest
. that should be doable for the vast majority of your cases.
select directory_path from dba_directories where upper(directory_name) = 'CSVDIR'
There's no need to use external modules, with just one line you can have the file name and relative path. If you are using modules and need to apply a path relative to the script directory, the relative path is enough.
$0 =~ m/(.+)[\/\\](.+)$/;
print "full path: $1, file name: $2\n";
You can try to add some time.sleep
calls to your code.
It seems like the server side limits the amount of requests per timeunit (hour, day, second) as a security issue. You need to guess how many (maybe using another script with a counter?) and adjust your script to not surpass this limit.
In order to avoid your code from crashing, try to catch this error with try .. except
around the urllib2 calls.
If you grab the MVC Futures assembly (which I would highly recommend) you can then use a generic when creating the ActionLink and a lambda to construct the route:
<%=Html.ActionLink<Product>(c => c.Action( o.Value ), "Details" ) %>
You can get the futures assembly here: http://aspnet.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=24471
I've improved Josh's answer. I've noticed that dig
only shows entries already present in the queried nameserver's cache, so it's better to pull an authoritative nameserver from the SOA (rather than rely on the default nameserver). I've also disabled the filtering of wildcard IPs because usually I'm usually more interested in the correctness of the setup.
The new script takes a -x
argument for expanded output and a -s NS
argument to choose a specific nameserver: dig -x example.com
#!/bin/bash
set -e; set -u

esac; done

test "${NS:-}" || NS=$(dig +short SOA "$DOM" | awk '{print $1}')
test "$NS" && NS="@$NS"
if test "$EXTENDED"; then
dig +nocmd $NS "$DOM" +noall +answer "$TYPE"
wild_ips=$(dig +short "$NS" "*.$DOM" "$TYPE" | tr '\n' '|')

It seems to me that simply: ls -lt mydirectory
does the job...
It seems you are hitting a UTF-8 byte order mark (BOM). Try using this unicode string with BOM extracted out:
import codecs
content = unicode(q.content.strip(codecs.BOM_UTF8), 'utf-8')
parser.parse(StringIO.StringIO(content))
I used strip
instead of lstrip
because in your case you had multiple occurences of BOM, possibly due to concatenated file contents.
Many people have already suggested testing 'hasattr', but there's a simpler answer:
def func():
func.counter = getattr(func, 'counter', 0) + 1
No try/except, no testing hasattr, just getattr with a default.
just continuing what @Mulki made with his code

where url is a url of the tomcat server that should be available, for example:
wget http://localhost:8080

Then check the exit code, if it's 0 - tomcat is up.

You can also enter msinfo32
into the command line.
It will bring up all your system information. Then, in the find box, just enter processor
and it will show you your cores and logical processors for each CPU. I found this way to be easiest.
To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100
in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application.
If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.
You can follow these steps :
$('SelectorToPrint').printElement();
I like this example, it uses the macro to approximate the value of PI. The larger the circle, the more accurate the approximation.

This is a standalone example showing how to save the output of a user-written function in Python 3:
from io import StringIO
import sys
def print_audio_tagging_result(value):
print(f"value = {value}")
tag_list = []
for i in range(0,1):
save_stdout = sys.stdout
result = StringIO()
sys.stdout = result
print_audio_tagging_result(i)
sys.stdout = save_stdout
tag_list.append(result.getvalue())
print(tag_list)
Yep, you'll want to do something like this:
echo -n "Enter Fullname: "
read fullname
Another option would be to have them supply this information on the command line. Getopts is your best bet there.
Using getopts in bash shell script to get long and short command line options
I followed this tutorial from Paul DeCarlo to use the Bash from the Windows Subsystem for Linux (WSL) instead of what comes with Git Bash for Windows. They are the same steps as above in the answer, but use the below in your User Settings instead.
"terminal.integrated.shell.windows": "C:\\Windows\\sysnative\\bash.exe",
This worked for me the first time... which is rare for this stuff.
The files need to be in a JPEG or PNG format of 24 bits, in a 2:1 ratio if it is a portrait and a 16:9 ratio for landscapes. Be careful that if you go for different sizes: the maximum size should not be more than twice bigger than the minimum size.
best answer written by Dmitri Korotkevitch:
Speaking of the installation, SQL Server 2008 allows you to set authentication mode (Windows or SQL Server) during the installation process. You will be forced to choose the strong password for sa user in the case if you choose sql server authentication mode during setup.
If you install SQL Server with Windows Authentication mode and want to change it, you need to do 2 different things:
Go to SQL Server Properties/Security tab and change the mode to SQL Server authentication mode
Go to security/logins, open SA login properties
a. Uncheck "Enforce password policy" and "Enforce password expiration" check box there if you decide to use weak password
b. Assign password to SA user
c. Open "Status" tab and enable login.
I don't need to mention that every action from above would violate security best practices that recommend to use windows authentication mode, have sa login disabled and use strong passwords especially for sa login.
We can assign a variable for curl using single quote '
and wrap some other variables in double-single-double quote "'"
for substitution inside curl-variable. Then easily we can use that curl-variable which here is MERGE
.
Example:
# other variables ...
REF_NAME="new-branch";
# variable for curl using single quote => ' not double "
MERGE='{
"repository": "tmp",
"command": "git",
"args": [
"pull",
"origin",
"'"$REF_NAME"'"
],
"options": {
"cwd": "/home/git/tmp"
}
}';
notice this line:
"'"$REF_NAME"'"
and then calling curl as usual:
curl -s -X POST localhost:1365/M -H 'Content-Type: application/json' --data "$MERGE"
I think he's using Python 3.0 and you're using Python 2.6.
I'd like to add another vote for the StringFormat object. You can use this simply to specify "center, center" and the text will be drawn centrally in the rectangle or points provided:
StringFormat format = new StringFormat();
format.LineAlignment = StringAlignment.Center;
format.Alignment = StringAlignment.Center;
However there is one issue with this in CF. If you use Center for both values then it turns TextWrapping off. No idea why this happens, it appears to be a bug with the CF.
You can use the forName
method of Class
:
Class cls = Class.forName(clsName);
Object obj = cls.newInstance();
Vanilla JS Solution. It works for a whole form not only one input.
In question selected JavaScript tag.
HTML Form:
var form = document.querySelector('form')_x000D_
var inputs = form.querySelectorAll('input')_x000D_
var required_inputs = form.querySelectorAll('input[required]')_x000D_
var register = document.querySelector('input[type="submit"]')_x000D_
form.addEventListener('keyup', function(e) {_x000D_
var disabled = false_x000D_
inputs.forEach(function(input, index) {_x000D_
if (input.value === '' || !input.value.replace(/\s/g, '').length) {_x000D_
disabled = true_x000D_
}_x000D_
})_x000D_

Some explanation:
In this code we add keyup event on html form and on every keypress check all input fields. If at least one input field we have are empty or contains only space characters then we assign the true value to disabled variable and disable submit button.
If you need to disable submit button until all required input fields are filled in - replace:
inputs.forEach(function(input, index) {
with:
required_inputs.forEach(function(input, index) {
where required_inputs is already declared array containing only required input fields.
Not really, Sorry! But...
Adding begin

creates regions which would look like this...bit of hack though!
Otherwise you can only expand and collapse you just can't dictate what should be expanded and collapsed. Not without a third-party tool such as SSMS Tools Pack.
A perfect 1/3 cannot exist in CSS with full cross browser support (anything below IE9). I personally would do: (It's not the perfect solution, but it's about as good as you'll get for all browsers)
#c1, #c2 {
width: 33%;
}
#c3 {
width: auto;
}
According to what I see by using .NET Reflector:
[Serializable, ComVisible(true)]
public abstract class DictionaryBase : IDictionary, ICollection, IEnumerable
{
// Fields
private Hashtable hashtable;
// Methods
protected DictionaryBase();
public void Clear();
.
.
.
}
Take note of these lines
// Fields
private Hashtable hashtable;
So we can be sure that DictionaryBase uses a HashTable internally.
Unless you need to access more memory that 32b addressing will allow you, the benefits will be small, if any.
When running on 64b CPU, you get the same memory interface no matter if you are running 32b or 64b code (you are using the same cache and same BUS).
While x64 architecture has a few more registers which allows easier optimizations, this is often counteracted by the fact pointers are now larger and using any structures with pointers results in a higher memory traffic. I would estimate the increase in the overall memory usage for a 64b application compared to a 32b one to be around 15-30 %.
You cannot sanely depend on client side JavaScript to determine if user credentials are correct. The browser (and all code that executes that) is under the control of the user, not you, so it is not trustworthy.
The username and password need to be entered using a form. The OK button will be a submit button. The action attribute must point to a URL which will be handled by a program that checks the credentials.
This program could be written in JavaScript, but how you go about that would depend on which server side JavaScript engine you were using. Note that SSJS is not a mainstream technology so if you really want to use it, you would have to use specialised hosting or admin your own server.
(Half a decade later and SSJS is much more common thanks to Node.js, it is still fairly specialised though).
If you want to redirect afterwards, then the program needs to emit an HTTP Location header.
Note that you need to check the credentials are OK (usually by storing a token, which isn't the actual password, in a cookie) before outputting any private page. Otherwise anyone could get to the private pages by knowing the URL (and thus bypassing the login system).
ScheduledThreadPoolExecutor
has this ability, but it's quite heavyweight.
Timer
also has this ability but opens several thread even if used only once.
Here's a simple implementation with a test (signature close to Android's Handler.postDelayed()):
public class JavaUtil {
public static void postDelayed(final Runnable runnable, final long delayMillis) {
final long requested = System.currentTimeMillis();
new Thread(new Runnable() {
@Override
public void run() {
// The while is just to ignore interruption.
while (true) {
try {
long leftToSleep = requested + delayMillis - System.currentTimeMillis();
if (leftToSleep > 0) {
Thread.sleep(leftToSleep);
}
break;
} catch (InterruptedException ignored) {
}
}
runnable.run();
}
}).start();
}
}
Test:
@Test
public void testRunsOnlyOnce() throws InterruptedException {
long delay = 100;
int num = 0;
final AtomicInteger numAtomic = new AtomicInteger(num);
JavaUtil.postDelayed(new Runnable() {
@Override
public void run() {
numAtomic.incrementAndGet();
}
}, delay);
Assert.assertEquals(num, numAtomic.get());
Thread.sleep(delay + 10);
Assert.assertEquals(num + 1, numAtomic.get());
Thread.sleep(delay * 2);
Assert.assertEquals(num + 1, numAtomic.get());
}
WebRTC is designed for high-performance, high quality communication of video, audio and arbitrary data. In other words, for apps exactly like what you describe.
WebRTC apps need a service via which they can exchange network and media metadata, a process known as signaling. However, once signaling has taken place, video/audio/data is streamed directly between clients, avoiding the performance cost of streaming via an intermediary server.
WebSocket on the other hand is designed for bi-directional communication between client and server. It is possible to stream audio and video over WebSocket (see here for example), but the technology and APIs are not inherently designed for efficient, robust streaming in the way that WebRTC is.
As other replies have said, WebSocket can be used for signaling.
I maintain a list of WebRTC resources: strongly recommend you start by looking at the 2013 Google I/O presentation about WebRTC.
Not exactly, but I would check out some of the articles on string handling (amongst other things) by "Phil Factor" (geddit?) on Simple Talk.
MFMailComposeViewController is the way to go after the release of iPhone OS 3.0 software. You can look at the sample code or the tutorial I wrote.
I've been messing around with this for about four hours and decided to share this with you.
You can submit a form by clicking a checkbox but the weird thing is that when checking for the submission in php, you would expect the form to be set when you either check or uncheck the checkbox. But this is not true. The form only gets set when you actually check the checkbox, if you uncheck it it won't be set. the word checked at the end of a checkbox input type will cause the checkbox to display checked, so if your field is checked it will have to reflect that like in the example below. When it gets unchecked the php updates the field state which will cause the word checked the disappear.
You HTML should look like this:
<form method='post' action='#'>
<input type='checkbox' name='checkbox' onChange='submit();'
<?php if($page->checkbox_state == 1) { echo 'checked' }; ?>>
</form>
and the php:
if(isset($_POST['checkbox'])) {
// the checkbox has just been checked
// save the new state of the checkbox somewhere
$page->checkbox_state == 1;
} else {
// the checkbox has just been unchecked
// if you have another form ont the page which uses than you should
// make sure that is not the one thats causing the page to handle in input
// otherwise the submission of the other form will uncheck your checkbox
// so this this line is optional:
if(!isset($_POST['submit'])) {
$page->checkbox_state == 0;
}
}
Why not one more answer? setState()
and the setState()
-triggered render()
have both completed executing when you call componentDidMount()
(the first time render()
is executed) and/or componentDidUpdate()
(any time after render()
is executed). (Links are to ReactJS.org docs.)
Example with componentDidUpdate()
Caller, set reference and set state...
<Cmp ref={(inst) => {this.parent=inst}}>;
this.parent.setState({'data':'hello!'});
Render parent...
componentDidMount() { // componentDidMount() gets called after first state set
console.log(this.state.data); // output: "hello!"
}
componentDidUpdate() { // componentDidUpdate() gets called after all other states set
console.log(this.state.data); // output: "hello!"
}
Example with componentDidMount()
Caller, set reference and set state...
<Cmp ref={(inst) => {this.parent=inst}}>
this.parent.setState({'data':'hello!'});
Render parent...
render() { // render() gets called anytime setState() is called
return (
<ChildComponent
state={this.state}
/>
);
}
After parent rerenders child, see state in componentDidUpdate()
.
componentDidMount() { // componentDidMount() gets called anytime setState()/render() finish
console.log(this.props.state.data); // output: "hello!"
}
BigInteger would only be used if you know it will not be a decimal and there is a possibility of the long data type not being large enough. BigInteger has no cap on its max size (as large as the RAM on the computer can hold).
From here.
It is implemented using an int[]
:
110 /**
111 * The magnitude of this BigInteger, in <i>big-endian</i> order: the
112 * zeroth element of this array is the most-significant int of the
113 * magnitude. The magnitude must be "minimal" in that the most-significant
114 * int ({@code mag[0]}) must be non-zero. This is necessary to
115 * ensure that there is exactly one representation for each BigInteger
116 * value. Note that this implies that the BigInteger zero has a
117 * zero-length mag array.
118 */
119 final int[] mag;
From the source
From the Wikipedia article Arbitrary-precision arithmetic:
Several modern programming languages have built-in support for bignums, and others have libraries available for arbitrary-precision integer and floating-point math. Rather than store values as a fixed number of binary bits related to the size of the processor register, these implementations typically use variable-length arrays of digits.
CancelAsync
doesn't actually abort your thread or anything like that. It sends a message to the worker thread that work should be cancelled via BackgroundWorker.CancellationPending
. Your DoWork delegate that is being run in the background must periodically check this property and handle the cancellation itself.
The tricky part is that your DoWork delegate is probably blocking, meaning that the work you do on your DataSource must complete before you can do anything else (like check for CancellationPending). You may need to move your actual work to yet another async delegate (or maybe better yet, submit the work to the ThreadPool
), and have your main worker thread poll until this inner worker thread triggers a wait state, OR it detects CancellationPending.

Use the simple code example in "JSON.parse()":
var jsontext = '{"firstname":"Jesper","surname":"Aaberg","phone":["555-0100","555-0120"]}';
var contact = JSON.parse(jsontext);
and reversing it:
var str = JSON.stringify(arr);
This is the cleanest way... BY FAR:

Here is pro example of using multi proptypes and single proptype.
import React, { Component } from 'react';
import { string, shape, array, oneOfType } from 'prop-types';

render() {
const { title, data } = this.props;
return (

}
}
/**

MyComponent.propTypes = {
data: oneOfType([array, string, shape({})]),
title: string,
};
export default MyComponent;
You can do it using the foreach loop
DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];
foreach(DataRow row in dr_art_line_2.Rows)
{
QuantityInIssueUnit_value = Convert.ToInt32(row["columnname"]);
}

If you're using Maven 3, one option to work around this problem is to use the versions plugin http://www.mojohaus.org/versions-maven-plugin/
Specifically the commands,
mvn versions:set -DnewVersion=2.0-RELEASE
mvn versions:commit
This will update the parent and child poms to 2.0-RELEASE. You can run this as a build step before.
Unlike the release plugin, it doesn't try to talk to your source control
The simplest solution.
Thanks to my partner that gave me this answer.
You can set an onkeypress event on the input textbox like this:
onkeypress="validate(event)"
and then use regular expressions like this:
function validate(evt){
evt.value = evt.value.replace(/[^0-9]/g,"");
}
It will scan and remove any letter or sign different from number in the field.
Also, you may want to try Data::Dumper. Example:
use Data::Dumper;
# simple procedural interface
print Dumper($foo, $bar);
what about having the image be something selected by the user? Use a input:file tag and then after they select the image, show it on the clientside webpage? That is doable for most things. Right now i am trying to get it working for IE, but as with all microsoft products, it is a cluster fork().
This should do the trick.
Requires bootstrap.js.
Example => http://getbootstrap.com/javascript/#collapse
$('.nav li a').click(function() {
$('#nav-main').collapse('hide');
});
This does the same thing as adding 'data-toggle="collapse"' and 'href="yournavigationID"' attributes to navigation menus tags.
Try insmod
instead of modprobe. Modprobe
looks in the module directory /lib/modules/uname -r

If you're using the mysql native driver (common since php 5.3), and the mysqli extension, you can accomplish this with an asynchronous query:
<?php
// Here's an example query that will take a long time to execute.
$sql = "
select *
from information_schema.tables t1
join information_schema.tables t2
join information_schema.tables t3
join information_schema.tables t4
join information_schema.tables t5
join information_schema.tables t6
join information_schema.tables t7
join information_schema.tables t8
";
$mysqli = mysqli_connect('localhost', 'root', '');
$mysqli->query($sql, MYSQLI_ASYNC | MYSQLI_USE_RESULT);
$links = $errors = $reject = [];
$links[] = $mysqli;
// wait up to 1.5 seconds
$seconds = 1;
$microseconds = 500000;
$timeStart = microtime(true);
if (mysqli_poll($links, $errors, $reject, $seconds, $microseconds) > 0) {
echo "query finished executing. now we start fetching the data rows over the network...\n";
$result = $mysqli->reap_async_query();
if ($result) {
while ($row = $result->fetch_row()) {
// print_r($row);
if (microtime(true) - $timeStart > 1.5) {
// we exceeded our time limit in the middle of fetching our result set.
echo "timed out while fetching results\n";
var_dump($mysqli->close());
break;
}
}
}
} else {
echo "timed out while waiting for query to execute\n";
var_dump($mysqli->close());
}
The flags I'm giving to mysqli_query accomplish important things. It tells the client driver to enable asynchronous mode, while forces us to use more verbose code, but lets us use a timeout(and also issue concurrent queries if you want!). The other flag tells the client not to buffer the entire result set into memory.
By default, php configures its mysql client libraries to fetch the entire result set of your query into memory before it lets your php code start accessing rows in the result. This can take a long time to transfer a large result. We disable it, otherwise we risk that we might time out while waiting for the buffering to complete.
Note that there's two places where we need to check for exceeding a time limit:
You can accomplish similar in the PDO and regular mysql extension. They don't support asynchronous queries, so you can't set a timeout on the query execution time. However, they do support unbuffered result sets, and so you can at least implement a timeout on the fetching of the data.
For many queries, mysql is able to start streaming the results to you almost immediately, and so unbuffered queries alone will allow you to somewhat effectively implement timeouts on certain queries. For example, a
select * from tbl_with_1billion_rows
can start streaming rows right away, but,
select sum(foo) from tbl_with_1billion_rows
needs to process the entire table before it can start returning the first row to you. This latter case is where the timeout on an asynchronous query will save you. It will also save you from plain old deadlocks and other stuff.
ps - I didn't include any timeout logic on the connection itself.

From Dianne Hackborn:
Things That Cannot Change:
The most obvious and visible of these is the “manifest package name,” the unique name you give to your application in its AndroidManifest.xml. The name uses a Java-language-style naming convention, with Internet domain ownership helping to avoid name collisions. For example, since Google owns the domain “google.com”, the manifest package names of all of our applications should start with “com.google.” It’s important for developers to follow this convention in order to avoid conflicts with other developers.
Once you publish your application under its manifest package name, this is the unique identity of the application forever more. Switching to a different name results in an entirely new application, one that can’t be installed as an update to the existing application.
More on things you cannot change here
Regarding your question on the URL from Google Play, the package defined there is linked to the app's fully qualified package you have in your AndroidManifest.xml file. More on Google Play's link formats here.
You could use this jQuery plugin waitForImage or you could put you images into an hidden div or (width:0 and height:0) and use onload event on images.
If you only have like 2-3 images you can bind events and trigger them in a chain so after every image you can do some code.
If you're already using Boost, you can do it with boost string algorithms + boost lexical cast:
#include <boost/algorithm/string/predicate.hpp>
#include <boost/lexical_cast.hpp>
try {
if (boost::starts_with(argv[1], "--foo="))
foo_value = boost::lexical_cast<int>(argv[1]+6);
} catch (boost::bad_lexical_cast) {
// bad parameter
}
This kind of approach, like many of the other answers provided here is ok for very simple tasks, but in the long run you are usually better off using a command line parsing library. Boost has one (Boost.Program_options), which may make sense if you happen to be using Boost already.
Otherwise a search for "c++ command line parser" will yield a number of options.
This should solve your problem.
urllib and urllib2 are both Python modules that do URL request related stuff but offer different functionalities.
1) urllib2 can accept a Request object to set the headers for a URL request, urllib accepts only a URL.
2) urllib provides the urlencode method which is used for the generation of GET query strings, urllib2 doesn't have such a function. This is one of the reasons why urllib is often used along with urllib2.
Requests - Requests’ is a simple, easy-to-use HTTP library written in Python.
1) Python Requests encodes the parameters automatically so you just pass them as simple arguments, unlike in the case of urllib, where you need to use the method urllib.encode() to encode the parameters before passing them.
2) It automatically decoded the response into Unicode.
3) Requests also has far more convenient error handling.If your authentication failed, urllib2 would raise a urllib2.URLError, while Requests would return a normal response object, as expected. All you have to see if the request was successful by boolean response.ok

Beyond the bug that was discovered and fixed, I'll just note that the error message sre_constants.error: nothing to repeat
is a bit confusing. I was trying to use r'?.*'
as a pattern, and thought it was complaining for some strange reason about the *
, but the problem is actually that ?
is a way of saying "repeat zero or one times". So I needed to say r'\?.*'
to match a literal ?
The particular format for strptime
:
datetime.datetime.strptime(string_date, "%Y-%m-%d %H:%M:%S.%f")
#>>> datetime.datetime(2013, 9, 28, 20, 30, 55, 782000)
Or try this ;)
try {
this.setContentPane(
new JLabel(new ImageIcon(ImageIO.read(new File("your_file.jpeg")))));
} catch (IOException e) {};
You Need to take same height and width
and simply use the border-radius:360px;
What about trying with VLOOKUP
? The syntax is:
=VLOOKUP(cell you want to copy, range you want to copy, 1, FALSE).
It should do the trick.
For anyone looking for a solution to this with also wanting to cycle the elements, below might work -
from collections import deque
foo = ['A', 'B', 'C', 'D']
def prev_and_next(input_list):
CURRENT = input_list
PREV = deque(input_list)
PREV.rotate(-1)
PREV = list(PREV)
NEXT = deque(input_list)
NEXT.rotate(1)
NEXT = list(NEXT)
return zip(PREV, CURRENT, NEXT)
for previous_, current_, next_ in prev_and_next(foo):
print(previous_, current_, next)
Instead of using regex to remove those "crazy" characters, just convert them to ASCII, which will remove accents, but will keep the letters.
astr <- "Ábcdêãçoàúü"
iconv(astr, from = 'UTF-8', to = 'ASCII//TRANSLIT')
which results in
[1] "Abcdeacoauu"
I Know this is a old question, and Pawel has given the correct answer, I just wanted to show a code example of how to do some string processing, and avoid an extra class for the list of a primitive type.
public class Test
{
public Test()
{
_strings = new List<string>
{
"test",
"test2",
"test3",
"test4"
};
}
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
private List<String> _strings { get; set; }
public List<string> Strings
{
get { return _strings; }
set { _strings = value; }
}
[Required]
public string StringsAsString
{
get { return String.Join(',', _strings); }
set { _strings = value.Split(',').ToList(); }
}
}
Cast the operands to floats:
float ans = (float)a / (float)b;
I had a similar problem. I was working on a project where I did not control the web.xml configuration file, so I could not use the changes suggested about altering the version. Of course the project was not using JSF so this was especially annoying for me.
I found that there is a really simple fix. Go to Preferences > Maven > Java EE Itegration and uncheck the "JSF Configurator" box.
I did this in a fresh workspace before importing the project again, but it may work equally as well on an existing project ... not sure.
function parseUtf8ToIso88591(&$string){
if(!is_null($string)){
$iso88591_1 = utf8_decode($string);
$iso88591_2 = iconv('UTF-8', 'ISO-8859-1', $string);
$string = mb_convert_encoding($string, 'ISO-8859-1', 'UTF-8');
}
}
To change image by using code
public void onClick(View v) {
if(v == ButtonName) {
ButtonName.setImageResource(R.drawable.ImageName);
}
}
Or, using an XML file:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="@drawable/login_selected" /> <!-- pressed -->
<item android:state_focused="true"
android:drawable="@drawable/login_mouse_over" /> <!-- focused -->
<item android:drawable="@drawable/login" /> <!-- default -->
</selector>
In OnClick
, just add this code:
ButtonName.setBackgroundDrawable(getResources().getDrawable(R.drawable.ImageName));
If you know the number of sheet you want to reference you can use below function to find out the name. Than you can use it in INDIRECT funcion.
Public Function GETSHEETNAME(address As String, Optional SheetNumber As Integer = 1) As String
Set WS = GetObject(address).Worksheets
GETSHEETNAME = WS(SheetNumber).Name
End Function
This solution doesn't require referenced workbook to be open - Excel gonna open it by itself (but it's gonna be hidden).
The following works for me in case you need last two tags (for example, in order to generate change log between current tag and the previous tag). I've tested it only in situation where the latest tag was the HEAD
.
PreviousAndCurrentGitTag=`git describe --tags \`git rev-list --tags --abbrev=0 --max-count=2\` --abbrev=0`
PreviousGitTag=`echo $PreviousAndCurrentGitTag | cut -f 2 -d ' '`
CurrentGitTag=`echo $PreviousAndCurrentGitTag | cut -f 1 -d ' '`
GitLog=`git log ${PreviousGitTag}..${CurrentGitTag} --pretty=oneline | sed "s_.\{41\}\(.*\)_; \1_"`
It suits my needs, but as I'm no git wizard, I'm sure it could be further improved. I also suspect it will break in case the commit history moves forward. I'm just sharing in case it helps someone.
beginupd.getTime()
will give you time in milliseconds since January 1, 1970, 00:00:00 GMT till the time you have specified in Date

You just need to use single quotes:
$ echo "$TEST"
test
$ echo '$TEST'
$TEST
Inside single quotes special characters are not special any more, they are just normal characters.
This is a broad question and there are multiple ways you can achieve this. In my experience, I've seen a lot of single page applications having an entry point file such as index.js
. This file would be responsible for 'bootstrapping' the application and will be your entry point for webpack.
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import Application from './components/Application';
const root = document.getElementById('someElementIdHere');
ReactDOM.render(
<Application />,
root,
);
Your <Application />
component would contain the next pieces of your app. You've stated you want different pages and that leads me to believe you're using some sort of routing. That could be included into this component along with any libraries that need to be invoked on application start. react-router
, redux
, redux-saga
, react-devtools
come to mind. This way, you'll only need to add a single entry point into your webpack configuration and everything will trickle down in a sense.
When you've setup a router, you'll have options to set a component to a specific matched route. If you had a URL of /about
, you should create the route in whatever routing package you're using and create a component of About.js
with whatever information you need.
Solution is to change Delimiter.
Content of the csv file -> Note .. Also space and , in value
Values are 6 Dutch word aap,noot,mies,Piet, Gijs, Jan
Col1;Col2;Col3
a,ap;noo,t;mi es
P,iet;G ,ijs;Ja ,n
$csv = Import-Csv C:\TejaCopy.csv -Delimiter ';'
Answer:
Write-Host $csv
@{Col1=a,ap; Col2=noo,t; Col3=mi es} @{Col1=P,iet; Col2=G ,ijs; Col3=Ja ,n}
It is possible to read a CSV file and use other Delimiter to separate each column.
It worked for my script :-)
Here is the answer to the question here
Actually we have to get it from the sharable ContentProvider of Camera Application.
EDIT . Copying answer that worked for me
private String getRealPathFromURI(Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
CursorLoader loader = new CursorLoader(mContext, contentUri, proj, null, null, null);
Cursor cursor = loader.loadInBackground();
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String result = cursor.getString(column_index);
cursor.close();
return result;
}
As Herman pointed out, you can get the index and element from each iteration.
{{range $index, $element := .}}{{$index}}
{{range $element}}{{.Value}}
{{end}}
{{end}}
Working example:
package main
import (
"html/template"
"os"
)
type EntetiesClass struct {
Name string
Value int32
}
// In the template, we use rangeStruct to turn our struct values
// into a slice we can iterate over
var htmlTemplate = `{{range $index, $element := .}}{{$index}}
{{range $element}}{{.Value}}
{{end}}
{{end}}`
func main() {
data := map[string][]EntetiesClass{
"Yoga": {{"Yoga", 15}, {"Yoga", 51}},
"Pilates": {{"Pilates", 3}, {"Pilates", 6}, {"Pilates", 9}},
}
t := template.New("t")
t, err := t.Parse(htmlTemplate)
if err != nil {
panic(err)
}
err = t.Execute(os.Stdout, data)
if err != nil {
panic(err)
}
}
Output:
Pilates
3
6
9
Yoga
15
51

I figure out the answer! You need to use the window.onload function as shown below. Thanks to Tec guy and Karim for the help. Note: You still need to use the document ready function too.
window.onload = function() {$('#logo').hide().fadeIn(3000);};
$(function() {$("#div").load(function() {$('#div').hide().fadeIn(750););
It also worked for me when placed right after the image...Thanks
You can also use relational algebra. A bit lengthy procedure, but here it is just to understand how MAX() works:
E := pID (Table_Name)
E1 := pID (sID >= ID' ((?ID' E) ? E)) – pID (sID < ID’ ((?ID' E) ? E))
Your answer: Table_Name ? E1
Basically what you do is subtract set of ordered relation(a,b) in which a<
b from A where a, b ? A.
For relation algebra symbols see: Relational algebra From Wikipedia
var clickButton = document.getElementById("<%= btnClearSession.ClientID %>");
clickButton.click();
That solution works for me, but remember it wont work if your asp button has
Visible="False"
To hide button that should be triggered with that script you should hide it with <div hidden></div>
Yes, JavaScript variables will exist in the scope they are created.
var bannerID = 55;
<input id="EditBanner" type="button"
value="Edit Image" onclick="EditBanner(bannerID);"/>
function EditBanner(id) {
//Do something with id
}
If you use event handlers and jQuery it is simple also
$("#EditBanner").click(function() {
EditBanner(bannerID);
});
What is the difference between NULL, ‘\0’ and 0
"null character (NUL)" is easiest to rule out. '\0'
is a character literal.
In C, it is implemented as int
, so, it's the same as 0, which is of INT_TYPE_SIZE
. In C++, character literal is implemented as char
, which is 1 byte. This is normally different from NULL
or 0
.
Next, NULL
is a pointer value that specifies that a variable does not point to any address space. Set aside the fact that it is usually implemented as zeros, it must be able to express the full address space of the architecture. Thus, on a 32-bit architecture NULL (likely) is 4-byte and on 64-bit architecture 8-byte. This is up to the implementation of C.
Finally, the literal 0
is of type int
, which is of size INT_TYPE_SIZE
. The default value of INT_TYPE_SIZE
could be different depending on architecture.

The 64-bit data model used by Mac OS X is known as "LP64". This is the common data model used by other 64-bit UNIX systems from Sun and SGI as well as 64-bit Linux. The LP64 data model defines the primitive types as follows:
- ints are 32-bit
- longs are 64-bit

You need to configure class ModeleREP

Have al look at OOXS
You cannot safely do what you want since the default hashCode() may not return the address, and has been mentioned, multiple objects with the same hashCode are possible. The only way to accomplish what you want, is to actually override the hashCode() method for the objects in question and guarantee that they all provide unique values. Whether this is feasible in your situation is another question.
For the record, I have experienced multiple objects with the same default hashcode in an IBM VM running in a WAS server. We had a defect where objects being put into a remote cache would get overwritten because of this. That was an eye opener for me at that point since I assumed the default hashcode was the objects memory address as well.
The result in isEmailValid
can be used to test whether the email's syntax is valid.
var validEmailRegEx = /^[A-Z0-9_'%=+!`#~$*?^{}&|-]+([\.][A-Z0-9_'%=+!`#~$*?^{}&|-]+)*@[A-Z0-9-]+(\.[A-Z0-9-]+)+$/i

This is what worked for me on Windows. The cause being multiple python installations
python -m pip uninstall pip setuptools
Today, I've got a similar error:
Servlet.service() for servlet [remoting] in context with path [/***] threw exception [Request processing failed; nested exception is java.lang.RuntimeException: buildDocument failed.] with root cause
org.xml.sax.SAXParseException; lineNumber: 19; columnNumber: 91; An invalid XML character (Unicode: 0xc) was found in the value of attribute "text" and element is "label".
After my first encouter with the error, I had re-typed the entire line by hand, so that there was no way for a special character to creep in, and Notepad++ didn't show any non-printable characters (black on white), nevertheless I got the same error over and over.
When I looked up what I've done different than my predecessors, it turned out it was one additional space just before the closing /> (as I've heard was recommended for older parsers, but it shouldn't make any difference anyway, by the XML standards):
<label text="this label's text" layout="cell 0 0, align left" />
When I removed the space:
<label text="this label's text" layout="cell 0 0, align left"/>
everything worked just fine.
So it's definitely a misleading error message.

CMD doesn't have time arithmetic. The following code, however gives a workaround:
set vid_time=11:07:48
set srt_time=11:16:58
REM Get time difference
set length=%vid_time%
for /f "tokens=1-3 delims=:" %i in ("%length%") do (
set /a h=%i*3600
set /a m=%j*60
set /a s=%k
)
set /a t1=!h!+!m!+!s!
set length=%srt_time%
for /f "tokens=1-3 delims=:" %i in ("%length%") do (
set /a h=%i*3600
set /a m=%j*60
set /a s=%k
)
set /a t2=!h!+!m!+!s!
cls
set /a diff=!t2!-!t1!
Above code gives difference in seconds. To display in hh:mm:ss format, code below:
set ss=!diff!
set /a hh=!ss!/3600 >nul
set /a mm="(!ss!-3600*!hh!)/60" >nul
set /a ss="(!ss!-3600*!hh!)-!mm!*60" >nul
set "hh=0!hh!" & set "mm=0!mm!" & set "ss=0!ss!"
echo|set /p=!hh:~-2!:!mm:~-2!:!ss:~-2!
I believe you want to use CHARINDEX
. You can read about it here.
It is the NextStep (= NS) heritage. NeXT was the computer company that Steve Jobs formed after he quit Apple in 1985, and NextStep was it's operating system (UNIX based) together with the Obj-C language and runtime. Together with it's libraries and tools, NextStep was later renamed OpenStep (which was also the name on an API that NeXT developed together with Sun), which in turn later became Cocoa.
These different names are actually quite confusing (especially since some of the names differs only in which characters are upper or lower case..), try this for an explanation:
Depending on what you mean with "ASCII character" you could simply try:
xxx.+xxx
I am all for Eran Harel's solution and in cases where it isn't possible, Tomasz Nurkiewicz's suggestion for spying is excellent. However, it's worth noting that there are situations where neither would apply. E.g. if the login
method was a bit "beefier":
public class TestedClass {
public LoginContext login(String user, String password) {
LoginContext lc = new LoginContext("login", callbackHandler);
lc.doThis();
lc.doThat();
return lc;
}
}
... and this was old code that could not be refactored to extract the initialization of a new LoginContext
to its own method and apply one of the aforementioned solutions.
For completeness' sake, it's worth mentioning a third technique - using PowerMock to inject the mock object when the new
operator is called. PowerMock isn't a silver bullet, though. It works by applying byte-code manipulation on the classes it mocks, which could be dodgy practice if the tested classes employ byte code manipulation or reflection and at least from my personal experience, has been known to introduce a performance hit to the test. Then again, if there are no other options, the only option must be the good option:
@RunWith(PowerMockRunner.class)
@PrepareForTest(TestedClass.class)
public class TestedClassTest {
@Test
public void testLogin() {
LoginContext lcMock = mock(LoginContext.class);
whenNew(LoginContext.class).withArguments(anyString(), anyString()).thenReturn(lcMock);
TestedClass tc = new TestedClass();
tc.login ("something", "something else");
// test the login's logic
}
}
For me the solution was to have
"location=0"
in the 3rd parameter. Tested on latest FF/Chrome and an old version of IE11
Full method call I use is below (As I like to use a variable width):

id + runat="server" leads to accessible at the server
You can also use a spline. Feed in the values you have and interpolate points between your known points. Linking this with a least-squares fit, moving average or kalman filter (as mentioned in other answers) gives you the ability to calculate the points inbetween your "known" points.
Being able to interpolate the values between your knowns gives you a nice smooth transition and a /reasonable/ approximation of what data would be present if you had a higher-fidelity. http://en.wikipedia.org/wiki/Spline_interpolation
Different splines have different characteristics. The one's I've seen most commonly used are Akima and Cubic splines.
Another algorithm to consider is the Ramer-Douglas-Peucker line simplification algorithm, it is quite commonly used in the simplification of GPS data. (http://en.wikipedia.org/wiki/Ramer-Douglas-Peucker_algorithm)
This works:
sc.exe config "[servicename]" obj= "[.\username]" password= "[password]"
Where each of the [bracketed] items are replaced with the true arguments. (Keep the quotes, but don't keep the brackets.)
Just keep in mind that:
obj= "foo"
is correct; obj="foo"
is not.You can call Grandpa::__construct from where you want and the $this keyword will refer to your current class instance. But be carefull with this method you cannot access to protected properties and methods of current instance from this other context, only to public elements. => All work and officialy supported.
Example
// main class that everything inherits
class Grandpa
{
public function __construct()
{
echo $this->one; // will print 1
echo $this->two; // error cannot access protected property
}
}
class Papa extends Grandpa
{
public function __construct()
{
// call Grandpa's constructor
parent::__construct();
}
}
class Kiddo extends Papa
{
public $one = 1;
protected $two = 2;
public function __construct()
{
Grandpa::__construct();
}
}
new Kiddo();
Depending on size and scale of the difficultly, you could create a scratch (temporary) branch and commit the current work there.
Then switch to and checkout your original branch, and pick the appropriate files from the scratch commit.
At least you would have a permanent record of the current and previous states to work from (until you delete that scratch branch).
You could always do just:
a=[1,2,3]
b=['a','b']
c=[1,2,3,4]
d=[1,2,3]
a==b #returns False
a==c #returns False
a==d #returns True
SRCS=$(wildcard *.c)
OBJS=$(SRCS:.c=.o)
all: $(OBJS)
var result = from sc in enumerableOfSomeClass
join soc in enumerableOfSomeOtherClass
on sc.Property1 equals soc.Property2
select new { SomeClass = sc, SomeOtherClass = soc };
Would be equivalent to:
var result = enumerableOfSomeClass
.Join(enumerableOfSomeOtherClass,
sc => sc.Property1,
soc => soc.Property2,
(sc, soc) => new
{
SomeClass = sc,
SomeOtherClass = soc
});
As you can see, when it comes to joins, query syntax is usually much more readable than lambda syntax.
Here are a few ways to create a list with N of continuous natural numbers starting from 1.
1 range:
def numbers(n):
return range(1, n+1);
2 List Comprehensions:

return [i for i in range(1, n+1)]
You may want to look into the method xrange and the concepts of generators, those are fun in python. Good luck with your Learning!
Select your terminal Command prompt instead of Power shell. That should work.
Difference between show() and css({'display':'block'})
Assuming you have this at the beginning:
<span id="thisElement" style="display: none;">Foo</span>
when you call:
$('#thisElement').show();
you will get:
<span id="thisElement" style="">Foo</span>
while:
$('#thisElement').css({'display':'block'});
does:
<span id="thisElement" style="display: block;">Foo</span>
so, yes there's a difference.
Difference between hide() and css({'display':'none'})
same as above but change these into hide() and display':'none'......
Another difference
When .hide()
is called the value of the display property is saved in jQuery's data cache, so when .show()
is called, the initial display value is restored!
lateinit vs lazy
lateinit
i) Use it with mutable variable[var]
lateinit var name: String //Allowed
lateinit val name: String //Not Allowed
ii) Allowed with only non-nullable data types
lateinit var name: String //Allowed
lateinit var name: String? //Not Allowed
iii) It is a promise to compiler that the value will be initialized in future.
NOTE: If you try to access lateinit variable without initializing it then it throws UnInitializedPropertyAccessException.
lazy
i) Lazy initialization was designed to prevent unnecessary initialization of objects.
ii) Your variable will not be initialized unless you use it.
iii) It is initialized only once. Next time when you use it, you get the value from cache memory.
iv) It is thread safe(It is initialized in the thread where it is used for the first time. Other threads use the same value stored in the cache).
v) The variable can only be val.
vi) The variable can only be non-nullable.
new Date("2011-07-14 11:23:00");
works fine for me.
string = "firstName:name1, lastName:last1";
This will work:
var fields = string.split(', '),
fieldObject = {};
if( typeof fields === 'object') ){
fields.each(function(field) {
var c = property.split(':');
fieldObject[c[0]] = c[1];
});
}
However it's not efficient. What happens when you have something like this:
string = "firstName:name1, lastName:last1, profileUrl:http://localhost/site/profile/1";
split()
will split 'http'. So i suggest you use a special delimiter like pipe
string = "firstName|name1, lastName|last1";
var fields = string.split(', '),
fieldObject = {};
if( typeof fields === 'object') ){
fields.each(function(field) {
var c = property.split('|');
fieldObject[c[0]] = c[1];
});
}
Using .Equals is also a lot easier to read.
My crazy solution.)
$(document).ready(function() {
$("td").each(function(index) {
var htmlText = "<div style='width:300px;'>" + $(this).text() +"</div>";
$(this).html(htmlText);
});
});
you can do this very easy by using following in sudo vi /etc/nginx/sites-available/default
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _ your_domain;
location /health {
access_log off;
return 200 "healthy\n";
}
location / {
proxy_pass http://localhost:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_cache_bypass $http_upgrade;
}
}
If an URL pattern starts with /
, then it's relative to the context root. The /Admin/*
URL pattern would only match pages on http://localhost:8080/EMS2/Admin/*
(assuming that /EMS2
is the context path), but you have them actually on http://localhost:8080/EMS2/faces/Html/Admin/*
, so your URL pattern never matches.
You need to prefix your URL patterns with /faces/Html
as well like so:
<url-pattern>/faces/Html/Admin/*</url-pattern>
You can alternatively also just reconfigure your web project structure/configuration so that you can get rid of the /faces/Html
path in the URLs so that you can just open the page by for example http://localhost:8080/EMS2/Admin/Upload.xhtml
.
Your filter mapping syntax is all fine. However, a simpler way to specify multiple URL patterns is to just use only one <filter-mapping>
with multiple <url-pattern>
entries:
<filter-mapping>
<filter-name>LoginFilter</filter-name>
<url-pattern>/faces/Html/Employee/*</url-pattern>
<url-pattern>/faces/Html/Admin/*</url-pattern>
<url-pattern>/faces/Html/Supervisor/*</url-pattern>
</filter-mapping>
run
ps -ef | grep name-related-to-process
above command will give all the details like pid, start time about the process.
like if you want all java realted process give java or if you have name of process place the name
To add to tacaswell's answer, the colorbar()
function has an optional cax
input you can use to pass an axis on which the colorbar should be drawn. If you are using that input, you can directly set a label using that axis.
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
fig, ax = plt.subplots()
heatmap = ax.imshow(data)
divider = make_axes_locatable(ax)
cax = divider.append_axes('bottom', size='10%', pad=0.6)
cb = fig.colorbar(heatmap, cax=cax, orientation='horizontal')
cax.set_xlabel('data label') # cax == cb.ax
$result = preg_replace('/ /', '%20', 'your string here');
you may also consider using
$result = urlencode($yourstring)
to escape other special characters as well
Note the point density in proportional to inverse square of the radius, hence instead of picking r
from [0, r_max]
, pick from [0, r_max^2]
, then compute your coordinates as:
x = sqrt(r) * cos(angle)
y = sqrt(r) * sin(angle)
This will give you uniform point distribution on a disk.
A simple intuitive implementation:
public static List<PointF> RemoveDuplicates(List<PointF> listPoints)
{
List<PointF> result = new List<PointF>();
for (int i = 0; i < listPoints.Count; i++)
{
if (!result.Contains(listPoints[i]))
result.Add(listPoints[i]);
}
return result;
}
If the types of the parameters are all the same (varchar2
for example), you can have a package like this which will do the following:
CREATE OR REPLACE PACKAGE testuser.test_pkg IS
TYPE assoc_array_varchar2_t IS TABLE OF VARCHAR2(4000) INDEX BY BINARY_INTEGER;
PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t);
END test_pkg;
CREATE OR REPLACE PACKAGE BODY testuser.test_pkg IS
PROCEDURE your_proc(p_parm IN assoc_array_varchar2_t) AS
BEGIN
FOR i IN p_parm.first .. p_parm.last
LOOP
dbms_output.put_line(p_parm(i));
END LOOP;
END;
END test_pkg;
Then, to call it you'd need to set up the array and pass it:
DECLARE
l_array testuser.test_pkg.assoc_array_varchar2_t;
BEGIN
l_array(0) := 'hello';
l_array(1) := 'there';
testuser.test_pkg.your_proc(l_array);
END;
/
This won't show custom events like those your script might create if it's a jquery plugin. for example :
jQuery(function($){
var ThingName="Something";
$("body a").live('click', function(Event){
var $this = $(Event.target);
$this.trigger(ThingName + ":custom-event-one");
});
$.on(ThingName + ":custom-event-one", function(Event){
console.log(ThingName, "Fired Custom Event: 1", Event);
})
});
The Event Panel under Scripts in chrome developer tools will not show you "Something:custom-event-one"
I just created a simple script that will bring back the $_SERVER['REMOTE_ADDR'] and $_SERVER['SERVER_ADDR'] in IIS so you don't have to change every variable. Just paste this text in your php file that is included in every page.
/** IIS IP Check **/
if(!$_SERVER['SERVER_ADDR']){ $_SERVER['SERVER_ADDR'] = $_SERVER['LOCAL_ADDR']; }
if(!$_SERVER['REMOTE_ADDR']){ $_SERVER['REMOTE_ADDR'] = $_SERVER['LOCAL_ADDR']; }

If I properly understood your question, supposing your running script is
/relative/path/to/script/index.php
This would give you the parent directory of your running script relative to the document www:
$parent_dir = dirname(dirname($_SERVER['SCRIPT_NAME'])) . '/';
//$parent_dir will be '/relative/path/to/'
If you want the parent directory of your running script relative to server root:
$parent_dir = dirname(dirname($_SERVER['SCRIPT_FILENAME'])) . '/';
//$parent_dir will be '/root/some/path/relative/path/to/'
I ran into the very same problem, tried out really everything that I could think of. Not being a fan of installing anything globally, but eventually had to run
npm install -g babel-cli
,
which solved my problem.
Maybe not the answer, but definitely a possible solution...
The issue is because your data source is not setup properly, to do that please verify your data source connection, in order to do that first navigate to Report Service Configuration Manager through
clicking on the start -> Start All -> Microsoft SQL Server ->Configuration Tool -> “Report Service Configuration Manager”
The open Report Manager URL and then navigate to the Data Source folder, see in the picture below
Then Create a Data Source or configure the one that is already there by right click on your database source and select "Manage" as is shown below
Now on the properties tab, on your left menu, fill out the data source with your connection string and username and password, after that click on test connection, and if the connection was successful, then click "Apply"
Navigate to the folder that contains your report in this case "SurveyLevelReport"
And Finally set your Report to the Data Source that you set up previously, and click Apply
You can write a function to return array of occurrence positions, Java has String.regionMatches function which is quite handy
public static ArrayList<Integer> occurrencesPos(String str, String substr) {
final boolean ignoreCase = true;
int substrLength = substr.length();
int strLength = str.length();
ArrayList<Integer> occurrenceArr = new ArrayList<Integer>();
for(int i = 0; i < strLength - substrLength + 1; i++) {
if(str.regionMatches(ignoreCase, i, substr, 0, substrLength)) {
occurrenceArr.add(i);
}
}
return occurrenceArr;
}
These days you can also use the Web API ResizeObserver
.
Simple example:
const resizeObserver = new ResizeObserver(() => {
console.log('size changed');
});
resizeObserver.observe(document.querySelector('#myElement'));
If you could use MariaDB there is a very very easy solution.
Since MariaDB-10.02 there has been added a new storage engine called CONNECT that can help us to convert the results of another query or table into a pivot table, just like what you want: You can have a look at the docs.
First of all install the connect storage engine.
Now the pivot column of our table is itemname
and the data for each item is located in itemvalue
column, so we can have the result pivot table using this query:
create table pivot_table
engine=connect table_type=pivot tabname=history
option_list='PivotCol=itemname,FncCol=itemvalue';
Now we can select what we want from the pivot_table
:
select * from pivot_table
usually __iter__()
just return self if you have already define the next() method (generator object):
here is a Dummy example of a generator :
class Test(object):
def __init__(self, data):
self.data = data
def next(self):
if not self.data:
raise StopIteration
return self.data.pop()
def __iter__(self):
return self
but __iter__()
can also be used like this:
http://mail.python.org/pipermail/tutor/2006-January/044455.html
This is 2 step process
If you want to push your branch code to remote repo then do
Since you tagged Java-ee as well - then YES it is possible.
and in core java as well it is possible using static blocks
and check this How can you run a Java program without main method?
Edit:
as already pointed out in other answers - it does not support from Java 7
To get or set the Password in a PasswordBox, use the Password property. Such as
string password = PasswordBox.Password;
This doesn't support Databinding as far as I know, so you'd have to set the value in the codebehind, and update it accordingly.
I ran into the same exact problem around noon today and finally found a solution here --> Trying to resize2fs EB volume fails
I skipped mounting, since the partition was already mounted.
Apparently CentOS 7 uses XFS as the default file system and as a result resize2fs
will fail.
I took a look in /etc/fstab
, and guess what, XFS was staring me in the face... Hope this helps.
Changing
RestResponse response = client.Execute(request);
to
IRestResponse response = client.Execute(request);
worked for me.
To follow up on Ron's answer if using JQuery and putting it in application.js or the head section you need to wrap it in a ready() section...
$(document).ready(function() {
$('#my-link').click(function(event){
alert('Hooray!');
event.preventDefault(); // Prevent link from following its href
});
});
AFAIK, {...}
can only be used as a path, not inside a query-param. Try this instead:
public interface FooService {
@GET("/maps/api/geocode/json?sensor=false")
void getPositionByZip(@Query("address") String address, Callback<String> cb);
}
If you have an unknown amount of parameters to pass, you can use do something like this:
public interface FooService {
@GET("/maps/api/geocode/json")
@FormUrlEncoded
void getPositionByZip(@FieldMap Map<String, String> params, Callback<String> cb);
}
WebApiConfig is the place where you can configure whether you want to output in json or xml. By default, it is xml. In the register function, we can use HttpConfiguration Formatters to format the output.
System.Net.Http.Headers => MediaTypeHeaderValue("text/html")
is required to get the output in the json format.
You would have got this Exception while doing a GET
on http://localhost:8080/projectname/login
As Vinay has correctly stated you can definitely use
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String displayLogin(Model model) {
model.addAttribute("login", new Login());
return "login";
}
But I am going to provide some alternative syntax which I think you were trying with Spring 3.0.
You can also achieve the above functionality with
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String displayLogin(Login loginModel) {
return "login";
}
and it login.jsp
(assuming you are using InternalResourceViewResolver
) you can have
<form:form method="POST" action="login.htm" modelAttribute="login">
Notice : modelAttribute is login
and not loginModel
. It is as per the class name you provide in argument. But if you want to use loginModel
as modelAttribute is jsp you can do the following
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String displayLogin(@ModelAttribute("loginModel")Login loginModel) {
return "login";
}
and jsp would have
<form:form method="POST" action="login.htm" modelAttribute="loginModel">
I know there are just different ways for doing the same thing. But the most important point to note here -
Imp Note: When you add your model class in your methods argument (like public String displayLogin(Login loginModel)
) it is automatically created and added to your Model object (which is why you can directly access it in JSP without manually putting it in model). Then it will search your request if request has attributes that it can map with the new ModelObject create. If yes Spring will inject values from request parameters to your custom model object class (Login in this case).
You can test this by doing
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String displayLogin(Login loginModel, Model model) {
System.out.println(model.asMap().get("login").equals(loginModel));
return "login";
}
Note : Above creating of new custom model object may not hold true if you have given @SessionAttributes({"login"})
. In this case it will get from session and populate values.
@echo off
title Test
echo Select a language. (de/en)
set /p language=
IF /i "%language%"=="de" goto languageDE
IF /i "%language%"=="en" goto languageEN
echo Not found.
goto commonexit
:languageDE
echo German
goto commonexit
:languageEN
echo English

pause
The point is that batch simply continues through instructions, line by line until it reaches a goto
, exit
or end-of-file. It has no concept of sections
to control flow.
Hence, entering de
would jump to :languagede
then simply continue executing instructions until the file ends, showing de
then en
then not found
.
You probably want to use the assets_base_urls
configuration.

assets_base_urls:
http: [http://www.website.com]

Note that the configuration is different since Symfony 2.7:
framework:

Some applications may detect click source at low OS level. If you really need that kind of hack, you may just run target app in virtual machine's window, and run cliker in host OS, it can help.
Swift: You need to add a subview with clip to bounds
var DateView = UIView(frame: CGRectMake(0, 0, view.frame.width, 100))
DateView.layer.borderWidth=1
DateView.clipsToBounds = true
var myDatepicker = UIDatePicker(frame:CGRectMake(0,-20,view.frame.width,162));
DateView.addSubview(myDatepicker);
self.view.addSubview(DateView)
This should add a clipped 100 height date picker in the top of the view controller.
In JavaScript first focus on the control and then select the control to display the cursor on texbox...
document.getElementById(frmObj.id).focus();
document.getElementById(frmObj.id).select();
or by using jQuery
$("#textboxID").focus();
When you specify a percentage for max-height
on a child, it is a percentage of the parent's actual height, not the parent's max-height
, oddly enough. The same applies to max-width
.
So, when you don't specify an explicit height on the parent, then there's no base height for the child's max-height
to be calculated from, so max-height
computes to none
, allowing the child to be as tall as possible. The only other constraint acting on the child now is the max-width
of its parent, and since the image itself is taller than it is wide, it overflows the container's height downwards, in order to maintain its aspect ratio while still being as large as possible overall.
When you do specify an explicit height for the parent, then the child knows it has to be at most 100% of that explicit height. That allows it to be constrained to the parent's height (while still maintaining its aspect ratio).
There is no python3.exe file, that is why it fails.
Try:
py
instead.
py is just a launcher for python.exe. If you have more than one python versions installed on your machine (2.x, 3.x) you can specify what version of python to launch by
py -2 or py -3
The "nav nav-list" class of Twiter Bootstrap 2.0 is handy for building a side bar.

Another way of adding schema dynamically or if you want to change it to something else
DECLARE @schema AS VARCHAR(256) = 'dbo.'
--User can also use SELECT SCHEMA_NAME() to get the default schema name
DECLARE @ID INT
declare @SQL nvarchar(max) = 'EXEC ' + @schema +'spSelectCaseBookingDetails @BookingID = ' + CAST(@ID AS NVARCHAR(10))
No need to cast @ID if it is nvarchar or varchar
execute (@SQL)
You can't set the size of your background image with the current version of CSS (2.1).
You can only set: position

I wrote a script that ended up being used every day in my team. When I used to work for Intel we had an app that talked to an access database to grab a dump of register information (I worked on validating chipsets). It would take this information (from a SQL query) and dump it into a CSV file, HTML file, and an Excel file. The whole process took almost 2 hours. No joke. No idea why it took so long. We would start it up an hour before lunch, go to lunch, and then come back.
I thought that there had to be a better way of doing this. I talked to the team that maintained the registry database and got the SQL code from them. I then wrote a perl script that grabbed the data and outputted it into CSV, HTML, and Excel formats. Runtime? Around 1-2 seconds. A great speed improvement.
I also wrote a few scripts while I was on deployment in Iraq in 2006 (I served in the National Guard for 9 years - got out in December). We used this old app called ULLS-G (Unit Level Logistics System - Ground) that was written in ADA and originally ran on DOS. They hacked it enough to where it would run on Windows XP in a command shell. This system didn't have a mouse interface. Everything was via keyboard and it had NO batch functionality. So let's say you wanted to print out licenses for all vehicle operators? Well... we had 150 soldiers in our unit so it took a LONG time. Let's say everyone got qualified on a new vehicle and you wanted to add it to everyone's operator qualifications? You had to do it one by one.
I was able to find an ODBC driver for the SAGE database (what ULLS-G used) and so I wrote perl scripts that were able to talk to the SAGE database. So things that took over an hour, now took only a few seconds. I also used my scripts and the driver for reporting. We had to report all information up to battalion every morning. Other units would write the information in by hand every morning. I whipped up an Excel macro that talked used the same driver and talked to the SAGE database and updated the Excel spreadsheet that way. It's the most complicated and only Excel macro I've ever written. It paid off because they awarded me the Army Commendation Medal. So yeah, I got a medal in the military for writing perl scripts :) How many can say that? ;)
I would use hide_input_all
from nbextensions (https://github.com/ipython-contrib/IPython-notebook-extensions). Here's how:
Find out where your IPython directory is:
from IPython.utils.path import get_ipython_dir
print get_ipython_dir()
Download nbextensions and move it to the IPython directory.
Edit your custom.js file somewhere in the IPython directory (mine was in profile_default/static/custom) to be similar to the custom.example.js in the nbextensions directory.
Add this line to custom.js:
IPython.load_extensions('usability/hide_input_all')
IPython Notebook will now have a button to toggle code cells, no matter the workbook.
Can't you implement your own timeout system?
Keep a sorted list, or better yet a priority heap as Heath suggests, of timeout events. In your select or poll calls use the timeout value from the top of the timeout list. When that timeout arrives, do that action attached to that timeout.
That action could be closing a socket that hasn't connected yet.
b = a(find(a~=0))
To expand on this answer, for the lazy of us:
function echocolor() { # $1 = string
COLOR='\033[1;33m'
NC='\033[0m'
printf "${COLOR}$1${NC}\n"
}
echo "This won't be colored"
echocolor "This will be colorful"
Add some CSS:
div#nav{
text-align: center;
}
div#nav ul{
display: inline-block;
}
You can try one even more simple:
<option value="1" ${item.quantity == 1 ? "selected" : ""}>1</option>
This difference is due to the behavior of Promises more than fetch()
specifically.
When a .then()
callback returns an additional Promise
, the next .then()
callback in the chain is essentially bound to that Promise, receiving its resolve or reject fulfillment and value.
The 2nd snippet could also have been written as:
iterator.then(response =>
response.json().then(post => document.write(post.title))
);
In both this form and yours, the value of post
is provided by the Promise returned from response.json()
.
When you return a plain Object
, though, .then()
considers that a successful result and resolves itself immediately, similar to:
iterator.then(response =>
Promise.resolve({
data: response.json(),
status: response.status
})
.then(post => document.write(post.data))
);
post
in this case is simply the Object
you created, which holds a Promise
in its data
property. The wait for that promise to be fulfilled is still incomplete.
Seven years after the inception of the App Store (July 10, 2008), Apple has finally introduced a new feature in Xcode 7 that allows you to deploy and run any number of apps on any of your devices, simply by logging in with your Apple ID. You will no longer need a paid Program membership to deploy apps on your own device (and you certainly no longer have to jailbreak your device if you're not comfortable doing so).
Well, not for the majority of use cases anyway. For obvious reasons, certain capabilities and entitlements that require Program membership such as Game Center and in-app purchases will not be available to apps deployed using this method. From Apple's developer documentation:
Launch Your App on Devices Using Free Provisioning (iOS, watchOS)
If you don’t join the Apple Developer Program, you can still build and run your app on your devices using free provisioning. However, the capabilities available to your app, described in Adding Capabilities, are restricted when you don’t belong to the Apple Developer Program.
The precise steps to getting your app onto your iOS device or Apple Watch follow immediately thus (screenshots omitted for ease of skimming):
In Xcode, add your Apple ID to Accounts preferences, described in Adding Your Apple ID Account in Xcode.
In the project navigator, select the project and your target to display the project editor.
Click General and choose your name from the Team pop-up menu.
Connect the device to your Mac and choose your device from the Scheme toolbar menu.
Below the Team pop-up menu, click Fix Issue.
Xcode creates a free provisioning profile for you and the warning text under the Team pop-up menu disappears.
Click the Run button.
Xcode installs the app on the device before launching the app.
Prior to Xcode 7, a Program membership was indeed required in order to sign the provisioning certificates required to deploy apps to devices. The only other alternative was jailbreaking. With Xcode 7, you no longer need to jailbreak your device just to run apps distributed outside the App Store, or to test apps if you cannot afford to join the Program, or to deploy and use apps that you have developed for your own personal use if you do not intend to distribute them through the App Store (in which case you probably don't need the entitlements offered by Program membership anyway).
