For completion sake:
#table_id td:nth-child(2) {white-space: nowrap;}
Is used for applying a style to the 2 column of the table_id
table.
This is supported by all major Browsers, IE started supporting this from IE9 onwards.
I am adding my solution to this problem.
I don't want to use image and validator will punish you for using negative values in CSS, so I go this way:
ul { list-style:none; padding:0; margin:0; }
li { padding-left:0.75em; position:relative; }
li:before { content:"•"; color:#e60000; position:absolute; left:0em; }
Here a single line Solution:
((LinearLayout.LayoutParams) yourLinearLayout.getLayoutParams()).marginToAdd = ((int)(Resources.getSystem().getDisplayMetrics().density * yourDPValue));
You can add android:layoutDirection="rtl"
but it's only available with API 17.
This is what I came up with. Here is a fiddle.
First, I need three wrapper elements for both a square shape and centered text.
<div><div><div>Lorem ipsum dolor sit amet, consectetuer adipiscing elit,
sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat
volutpat.</div></div></div>
This is the stylecheet. It makes use of two techniques, one for square shapes and one for centered text.
body > div {
position:relative;
height:0;
width:50%; padding-bottom:50%;
}
body > div > div {
position:absolute; top:0;
height:100%; width:100%;
display:table;
border:1px solid #000;
margin:1em;
}
body > div > div > div{
display:table-cell;
vertical-align:middle; text-align:center;
padding:1em;
}
align-content
align-content
controls the cross-axis (i.e. vertical direction if the flex-direction
is row
, and horizontal if the flex-direction
is column
) positioning of multiple lines relative to each other.
(Think lines of a paragraph being vertically spread out, stacked toward the top, stacked toward the bottom. This is under a flex-direction
row paradigm).
align-items
align-items
controls the cross-axis of an individual line of flex elements.
(Think how an individual line of a paragraph is aligned, if it contains some normal text and some taller text like math equations. In that case, will it be the bottom, top, or center of each type of text in a line that will be aligned?)
Using jquery you might do something like this:
// To disable
$('#targetDiv').children().attr('disabled', 'disabled');
// To enable
$('#targetDiv').children().attr('enabled', 'enabled');
Here's a jsFiddle example: http://jsfiddle.net/monknomo/gLukqygq/
You could also select the target div's children and add a "disabled" css class to them with different visual properties as a callout.
//disable by adding disabled class
$('#targetDiv').children().addClass("disabled");
//enable by removing the disabled class
$('#targetDiv').children().removeClass("disabled");
Here's a jsFiddle with the as an example: https://jsfiddle.net/monknomo/g8zt9t3m/
Or, instead of setting margin and than overriding it, you can just set it properly right away with the following combo:
span:not(:first-of-type) {
margin-left: 5px;
}
span:not(:last-of-type) {
margin-right: 5px;
}
An ImageView gets setLayoutParams from View which uses ViewGroup.LayoutParams. If you use that, it will crash in most cases so you should use getLayoutParams() which is in View.class. This will inherit the parent View of the ImageView and will work always. You can confirm this here: ImageView extends view
Assuming you have an ImageView defined as 'image_view' and the width/height int defined as 'thumb_size'
The best way to do this:
ViewGroup.LayoutParams iv_params_b = image_view.getLayoutParams();
iv_params_b.height = thumb_size;
iv_params_b.width = thumb_size;
image_view.setLayoutParams(iv_params_b);
I'd refrain from using floats for this sort of thing; I'd rather use inline-block
.
Some more points to consider:
<head>
and <body>
doctype
Here's a better way to format your document:
<!DOCTYPE html>
<html>
<head>
<title>Website Title</title>
<style type="text/css">
* {margin: 0; padding: 0;}
#container {height: 100%; width:100%; font-size: 0;}
#left, #middle, #right {display: inline-block; *display: inline; zoom: 1; vertical-align: top; font-size: 12px;}
#left {width: 25%; background: blue;}
#middle {width: 50%; background: green;}
#right {width: 25%; background: yellow;}
</style>
</head>
<body>
<div id="container">
<div id="left">Left Side Menu</div>
<div id="middle">Random Content</div>
<div id="right">Right Side Menu</div>
</div>
</body>
</html>
Here's a jsFiddle for good measure.
inside the Android manifest file of your project, find the activity declaration of whose you want to fix the orientation and add the following piece of code ,
android:screenOrientation="landscape"
for landscape orientation and for portrait add the following code,
android:screenOrientation="portrait"
From ggplot2 2.0.0
you can use the margin =
argument of element_text()
to change the distance between the axis title and the numbers. Set the values of the margin
on t
op, r
ight, b
ottom, and l
eft side of the element.
ggplot(mpg, aes(cty, hwy)) + geom_point()+
theme(axis.title.y = element_text(margin = margin(t = 0, r = 20, b = 0, l = 0)))
margin
can also be used for other element_text
elements (see ?theme
), such as axis.text.x
, axis.text.y
and title
.
addition
in order to set the margin for axis titles when the axis has a different position (e.g., with scale_x_...(position = "top")
, you'll need a different theme setting - e.g. axis.title.x.top
. See https://github.com/tidyverse/ggplot2/issues/4343.
What about position: relative
for the outer div? In the example that hides the inner one. It also won't move it in its layout since you don't specify a top or left.
A common solution to this problem uses absolute positioning or cropped floats, but these are tricky in that they require extensive tuning if your columns change in number+size, and that you need to make sure your "main" column is always the longest. Instead, I'd suggest you use one of three more robust solutions:
display: flex
: by far the simplest & best solution and very flexible - but unsupported by IE9 and older.table
or display: table
: very simple, very compatible (pretty much every browser ever), quite flexible.display: inline-block; width:50%
with a negative margin hack: quite simple, but column-bottom borders are a little tricky.display:flex
This is really simple, and it's easy to adapt to more complex or more detailed layouts - but flexbox is only supported by IE10 or later (in addition to other modern browsers).
Example: http://output.jsbin.com/hetunujuma/1
Relevant html:
<div class="parent"><div>column 1</div><div>column 2</div></div>
Relevant css:
.parent { display: -ms-flex; display: -webkit-flex; display: flex; }
.parent>div { flex:1; }
Flexbox has support for a lot more options, but to simply have any number of columns the above suffices!
<table>
or display: table
A simple & extremely compatible way to do this is to use a table
- I'd recommend you try that first if you need old-IE support. You're dealing with columns; divs + floats simply aren't the best way to do that (not to mention the fact that multiple levels of nested divs just to hack around css limitations is hardly more "semantic" than just using a simple table). If you do not wish to use the table
element, consider css display: table
(unsupported by IE7 and older).
Example: http://jsfiddle.net/emn13/7FFp3/
Relevant html: (but consider using a plain <table>
instead)
<div class="parent"><div>column 1</div><div>column 2</div></div>
Relevant css:
.parent { display: table; }
.parent > div {display: table-cell; width:50%; }
/*omit width:50% for auto-scaled column widths*/
This approach is far more robust than using overflow:hidden
with floats. You can add pretty much any number of columns; you can have them auto-scale if you want; and you retain compatibility with ancient browsers. Unlike the float solution requires, you also don't need to know beforehand which column is longest; the height scales just fine.
KISS: don't use float hacks unless you specifically need to. If IE7 is an issue, I'd still pick a plain table with semantic columns over a hard-to-maintain, less flexible trick-CSS solution any day.
By the way, if you need your layout to be responsive (e.g. no columns on small mobile phones) you can use a @media
query to fall back to plain block layout for small screen widths - this works whether you use <table>
or any other display: table
element.
display:inline block
with a negative margin hack.Another alternative is to use display:inline block
.
Example: http://jsbin.com/ovuqes/2/edit
Relevant html: (the absence of spaces between the div
tags is significant!)
<div class="parent"><div><div>column 1</div></div><div><div>column 2</div></div></div>
Relevant css:
.parent {
position: relative; width: 100%; white-space: nowrap; overflow: hidden;
}
.parent>div {
display:inline-block; width:50%; white-space:normal; vertical-align:top;
}
.parent>div>div {
padding-bottom: 32768px; margin-bottom: -32768px;
}
This is slightly tricky, and the negative margin means that the "true" bottom of the columns is obscured. This in turn means you can't position anything relative to the bottom of those columns because that's cut off by overflow: hidden
. Note that in addition to inline-blocks, you can achieve a similar effect with floats.
TL;DR: use flexbox if you can ignore IE9 and older; otherwise try a (css) table. If neither of those options work for you, there are negative margin hacks, but these can cause weird display issues that are easy to miss during development, and there are layout limitations you need to be aware of.
I had a simular issue and resolved it using android:adjustViewBounds="true"
on the ImageView.
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:contentDescription="@string/banner_alt"
android:src="@drawable/banner_portrait" />
This should work:
// Gets linearlayout
LinearLayout layout = findViewById(R.id.numberPadLayout);
// Gets the layout params that will allow you to resize the layout
LayoutParams params = layout.getLayoutParams();
// Changes the height and width to the specified *pixels*
params.height = 100;
params.width = 100;
layout.setLayoutParams(params);
If you want to convert dip to pixels, use this:
int height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, <HEIGHT>, getResources().getDisplayMetrics());
To put in layman’s term :
without xmlns:android=”http://schemas.android.com/apk/res/android” android related tags wont be recognized in the xml document of our layout.
If you're OK with a JavaScript solution, there's a jQuery plug-in to do this in a cross-browser fashion - see http://azgtech.wordpress.com/2009/07/26/text-overflow-ellipsis-for-firefox-via-jquery/
Set the horizontalPolicy & VerticalPolicy for the controls/widgets to "Preferred".
The solution for this problem is just to add overflow: auto;
to the .content for making the content wrapper scrollable.
Furthermore, there are circumstances occurring along with Flexbox wrapper and overflowed
scrollable content like this codepen.
The solution is to add overflow: hidden (or auto);
to the parent of the wrapper (set with overflow: auto;) around large contents.
EditText state = (EditText) findViewById(R.id.txtState);
Pattern ps = Pattern.compile("^[a-zA-Z ]+$");
Matcher ms = ps.matcher(state.getText().toString());
boolean bs = ms.matches();
if (bs == false) {
if (ErrorMessage.contains("invalid"))
ErrorMessage = ErrorMessage + "state,";
else
ErrorMessage = ErrorMessage + "invalid state,";
}
It's working for me:
<%= image_tag( root_url + "images/rss.jpg", size: "50x50", :alt => "rss feed") -%>
Took @Piotr's answer and made it into a Swift extension. Make sure to set the image and title before calling this, so that the button sizes properly.
extension UIButton {
/// Makes the ``imageView`` appear just to the right of the ``titleLabel``.
func alignImageRight() {
if let titleLabel = self.titleLabel, imageView = self.imageView {
// Force the label and image to resize.
titleLabel.sizeToFit()
imageView.sizeToFit()
imageView.contentMode = .ScaleAspectFit
// Set the insets so that the title appears to the left and the image appears to the right.
// Make the image appear slightly off the top/bottom edges of the button.
self.titleEdgeInsets = UIEdgeInsets(top: 0, left: -1 * imageView.frame.size.width,
bottom: 0, right: imageView.frame.size.width)
self.imageEdgeInsets = UIEdgeInsets(top: 4, left: titleLabel.frame.size.width,
bottom: 4, right: -1 * titleLabel.frame.size.width)
}
}
}
You could try using the <col>
tag manage table styling for all rows but you will need to set the table-layout:fixed
style on the <table>
or the tables css class and set the overflow
style for the cells
http://www.w3schools.com/TAGS/tag_col.asp
<table class="fixed">
<col width="20px" />
<col width="30px" />
<col width="40px" />
<tr>
<td>text</td>
<td>text</td>
<td>text</td>
</tr>
</table>
and this be your CSS
table.fixed { table-layout:fixed; }
table.fixed td { overflow: hidden; }
You could add another empty layout below that one and set them both to have the same layout weight. They should get 50% of the space each.
For me on a div without fixed size and with dynamic content it worked using:
display:table;
word-break:break-all;
I was just looking for this... By using David's answer, I used a span and gave it some padding (height won't work + top margin issue)... Works like a charm;
See fiddle
<ul>
<li><a href="index.php">Home</a></li><span class="divider"></span>
<li><a href="about.php">About Us</a></li><span class="divider"></span>
<li><a href="#">Events</a></li><span class="divider"></span>
<li><a href="#">Forum</a></li><span class="divider"></span>
<li><a href="#">Contact</a></li>
</ul>
.divider {
border-left: 1px solid #8e1537;
padding: 29px 0 24px 0;
}
Use This function to set all Type of margins
public void setViewMargins(Context con, ViewGroup.LayoutParams params,
int left, int top , int right, int bottom, View view) {
final float scale = con.getResources().getDisplayMetrics().density;
// convert the DP into pixel
int pixel_left = (int) (left * scale + 0.5f);
int pixel_top = (int) (top * scale + 0.5f);
int pixel_right = (int) (right * scale + 0.5f);
int pixel_bottom = (int) (bottom * scale + 0.5f);
ViewGroup.MarginLayoutParams s = (ViewGroup.MarginLayoutParams) params;
s.setMargins(pixel_left, pixel_top, pixel_right, pixel_bottom);
view.setLayoutParams(params);
}
Just wrap all that inside a ScrollView
:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- Here you put the rest of your current view-->
</ScrollView>
As David Hedlund said, ScrollView
can contain just one item... so if you had something like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- bla bla bla-->
</LinearLayout>
You must change it to:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- bla bla bla-->
</LinearLayout>
</ScrollView>
I will try to explain it shortly.
First, you may notice that now you should use ConstraintLayout as requested by google (see androix library).
In your android studio projet, you can provide screen-specific layouts by creating additional res/layout/ directories. One for each screen configuration that requires a different layout.
This means you have to use the directory qualifier in both cases :
As a result, here is an exemple :
res/layout/main_activity.xml # For handsets
res/layout-land/main_activity.xml # For handsets in landscape
res/layout-sw600dp/main_activity.xml # For 7” tablets
res/layout-sw600dp-land/main_activity.xml # For 7” tablets in landscape
You can also use qualifier with res ressources files using dimens.xml.
res/values/dimens.xml # For handsets
res/values-land/dimens.xml # For handsets in landscape
res/values-sw600dp/dimens.xml # For 7” tablets
res/values/dimens.xml
<resources>
<dimen name="grid_view_item_height">70dp</dimen>
</resources>
res/values-land/dimens.xml
<resources>
<dimen name="grid_view_item_height">150dp</dimen>
</resources>
your_item_grid_or_list_layout.xml
<androidx.constraintlayout.widget.ConstraintLayout
android:id="@+id/constraintlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content
<ImageView
android:id="@+id/image"
android:layout_width="0dp"
android:layout_height="@dimen/grid_view_item_height"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:background="@drawable/border"
android:src="@drawable/ic_menu_slideshow">
</androidx.constraintlayout.widget.ConstraintLayout>

You can try this simple android dialog popup library. It is very simple to use on your activity.
When submit button is clicked try following code after including above lib in your code
Pop.on(this)
.with()
.title(R.string.title) //ignore if not needed
.icon(R.drawable.icon) //ignore if not needed
.cancelable(false) //ignore if not needed
.layout(R.layout.custom_pop)
.when(new Pop.Yah() {
@Override
public void clicked(DialogInterface dialog, View view) {
Toast.makeText(getBaseContext(), "Yah button clicked", Toast.LENGTH_LONG).show();
}
}).show();
Add one line in your gradle and you good to go
dependencies {
compile 'com.vistrav:pop:2.0'
}
Here is a pure-java implementation of background image repeating:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.bg_image);
BitmapDrawable bitmapDrawable = new BitmapDrawable(bmp);
bitmapDrawable.setTileModeXY(Shader.TileMode.REPEAT, Shader.TileMode.REPEAT);
LinearLayout layout = new LinearLayout(this);
layout.setBackgroundDrawable(bitmapDrawable);
}
In this case, our background image would have to be stored in res/drawable/bg_image.png.
Complete guide related to Screen sizes
JavaScript
For height:
document.body.clientHeight // Inner height of the HTML document body, including padding
// but not the horizontal scrollbar height, border, or margin
screen.height // Device screen height (i.e. all physically visible stuff)
screen.availHeight // Device screen height minus the operating system taskbar (if present)
window.innerHeight // The current document's viewport height, minus taskbars, etc.
window.outerHeight // Height the current window visibly takes up on screen
// (including taskbars, menus, etc.)
Note: When the window is maximized this will equal screen.availHeight
For width:
document.body.clientWidth // Full width of the HTML page as coded, minus the vertical scroll bar
screen.width // Device screen width (i.e. all physically visible stuff)
screen.availWidth // Device screen width, minus the operating system taskbar (if present)
window.innerWidth // The browser viewport width (including vertical scroll bar, includes padding but not border or margin)
window.outerWidth // The outer window width (including vertical scroll bar,
// toolbars, etc., includes padding and border but not margin)
Jquery
For height:
$(document).height() // Full height of the HTML page, including content you have to
// scroll to see
$(window).height() // The current document's viewport height, minus taskbars, etc.
$(window).innerHeight() // The current document's viewport height, minus taskbars, etc.
$(window).outerHeight() // The current document's viewport height, minus taskbars, etc.
For width:
$(document).width() // The browser viewport width, minus the vertical scroll bar
$(window).width() // The browser viewport width (minus the vertical scroll bar)
$(window).innerWidth() // The browser viewport width (minus the vertical scroll bar)
$(window).outerWidth() // The browser viewport width (minus the vertical scroll bar)
Absolutely possible. Many ways to do it. The fastest way, create condition with try - catch method.. try your certain font style condition, catch the error, and define the other font style.
You can use the RelativeLayout
.
Do you have a _ViewStart.cshtml
in this directory? I had the same problem you're having when I tried using _ViewStart. Then I renamed it _mydefaultview, moved it to the Views/Shared
directory, and switched to specifying no view in cshtml files where I don't want it, and specifying _mydefaultview for the rest. Don't know why this was necessary, but it worked.
If you want to try with java code. Here you go -
final LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
yourView.setLayoutParams(params);
params.gravity = Gravity.BOTTOM; // set gravity
This is not an answer for the OP, as he wanted the display dimensions in real pixels. I wanted the dimensions in "device-independent-pixels", and putting together answers from here https://stackoverflow.com/a/17880012/253938 and here https://stackoverflow.com/a/6656774/253938 I came up with this:
DisplayMetrics displayMetrics = Resources.getSystem().getDisplayMetrics();
int dpHeight = (int)(displayMetrics.heightPixels / displayMetrics.density + 0.5);
int dpWidth = (int)(displayMetrics.widthPixels / displayMetrics.density + 0.5);
Use RelativeLayout
, place your view in it, get RelativeLayout.LayoutParams
object from your view and set margins as you need. Then call requestLayout()
on your view. This is the only way I know.
You don't need to wrap everything in a DIV to achieve basic styling on inputs.
input[type="text"] {margin: 0 0 10px 0;}
will do the trick in most cases.
Semantically, one <br/> tag is okay between elements to position them. When you find yourself using multiple <br/>'s (which are semantic elements) to achieve cosmetic effects, that's a flag that you're mixing responsibilities, and you should consider getting back to basics.
You can set content view (or design) of an activity. For example you can do it like this too :
public void onCreate(Bundle savedinstanceState) {
super.onCreate(savedinstanceState);
Button testButon = new Button(this);
setContentView(testButon);
}
Also watch this tutorial too.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Left" />
<Button Width="30" Grid.Column="1" >Right</Button>
</Grid>
make sure your css reads:
margin: 0 auto;
Even though you're saying you have the left and right set to auto, you may be placing an error. Of course we wouldn't know though because you did not show us any code.
.align-bottom {
position: absolute;
bottom: 10px;
right: 10px;
}

Just create a new class extending ScrollView and override it's onMeasure
method.
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (maxHeight > 0){
int hSize = MeasureSpec.getSize(heightMeasureSpec);
int hMode = MeasureSpec.getMode(heightMeasureSpec);
switch (hMode){
case MeasureSpec.AT_MOST:
heightMeasureSpec = MeasureSpec.makeMeasureSpec(Math.min(hSize, maxHeight), MeasureSpec.AT_MOST);
break;
case MeasureSpec.UNSPECIFIED:
heightMeasureSpec = MeasureSpec.makeMeasureSpec(maxHeight, MeasureSpec.AT_MOST);
break;
case MeasureSpec.EXACTLY:
heightMeasureSpec = MeasureSpec.makeMeasureSpec(Math.min(hSize, maxHeight), MeasureSpec.EXACTLY);
break;
}
}
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
This is because h1
is a block element, so it will extend across the line (or the width you give).
You can make the border go only around the text by setting display:inline
on the h1
I have tried the awnsers before but this did not work. Now I jsut used a LinearLayout instead of a TextureView, now it is working without any problem. Hope it helps some others who have the same problem. :)
view = (LinearLayout) findViewById(R.id.view); //this is initialized in the constructor
openWindowOnButtonClick();
public void openWindowOnButtonClick()
{
view.setAlpha((float)0.5);
FloatingActionButton fb = (FloatingActionButton) findViewById(R.id.floatingActionButton);
final InputMethodManager keyboard = (InputMethodManager) getSystemService(getBaseContext().INPUT_METHOD_SERVICE);
fb.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
// check if the Overlay should be visible. If this value is false, it is not shown -> show it.
if(view.getVisibility() == View.INVISIBLE)
{
view.setVisibility(View.VISIBLE);
keyboard.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);
Log.d("Overlay", "Klick");
}
else if(view.getVisibility() == View.VISIBLE)
{
view.setVisibility(View.INVISIBLE);
keyboard.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);
}
you can go to the XML file
then focus your mouse cursor into your button, text view or whatever you choose for your layout, then press Alt + Enter
to fix it, after that the error will be gone.it works for me.
I've been struggling with this problem in one form or another for AGES, thank you, Thank You, THANK YOU.... :)
I just wanted to point out that you can get a generalizable solution from what Bob Lee's done by just extending View and overriding onMeasure. That way you can use this with any drawable you want, and it won't break if there's no image:
public class CardImageView extends View {
public CardImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public CardImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CardImageView(Context context) {
super(context);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
Drawable bg = getBackground();
if (bg != null) {
int width = MeasureSpec.getSize(widthMeasureSpec);
int height = width * bg.getIntrinsicHeight() / bg.getIntrinsicWidth();
setMeasuredDimension(width,height);
}
else {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
}
I'm expanding upon the great answer given by @TonyL. I'm adding Math.abs() to wrap the values, and also I take into account that jQuery might be in "no conflict" mode, like for instance in WordPress.
I recommend that you wrap the top and left values with Math.abs() as I have done below. If the window is too small, and your modal dialog has a close box at the top, this will prevent the problem of not seeing the close box. Tony's function would have had potentially negative values. A good example on how you end up with negative values is if you have a large centered dialog but the end user has installed several toolbars and/or increased his default font -- in such a case, the close box on a modal dialog (if at the top) might not be visible and clickable.
The other thing I do is speed this up a bit by caching the $(window) object so that I reduce extra DOM traversals, and I use a cluster CSS.
jQuery.fn.center = function ($) {
var w = $(window);
this.css({
'position':'absolute',
'top':Math.abs(((w.height() - this.outerHeight()) / 2) + w.scrollTop()),
'left':Math.abs(((w.width() - this.outerWidth()) / 2) + w.scrollLeft())
});
return this;
}
To use, you would do something like:
jQuery(document).ready(function($){
$('#myelem').center();
});
Here is how the standard keyboard behaves for each of these input types.
See this answer for more details.
You can also achieve this using a CSS Grids framework, such as YUI Grids or Blue Print CSS. They solve alot of the cross browser issues and make more sophisticated column layouts possible for use mere mortals.
For those looking for an inline example, here is one:
<audio controls style="width: 200px;">
<source src="http://somewhere.mp3" type="audio/mpeg">
</audio>
It doesn't seem to respect a "height" setting, at least not awesomely. But you can always "customize" the controls but creating your own controls (instead of using the built-in ones) or using somebody's widget that similarly creates its own :)
From the iosched app source I came up with this ButtonBar
class:
/**
* An extremely simple {@link LinearLayout} descendant that simply reverses the
* order of its child views on Android 4.0+. The reason for this is that on
* Android 4.0+, negative buttons should be shown to the left of positive buttons.
*/
public class ButtonBar extends LinearLayout {
public ButtonBar(Context context) {
super(context);
}
public ButtonBar(Context context, AttributeSet attributes) {
super(context, attributes);
}
public ButtonBar(Context context, AttributeSet attributes, int def_style) {
super(context, attributes, def_style);
}
@Override
public View getChildAt(int index) {
if (_has_ics)
// Flip the buttons so that "OK | Cancel" becomes "Cancel | OK" on ICS
return super.getChildAt(getChildCount() - 1 - index);
return super.getChildAt(index);
}
private final static boolean _has_ics = Build.VERSION.SDK_INT >=
Build.VERSION_CODES.ICE_CREAM_SANDWICH;
}
This will be the LinearLayout
that the "OK" and "Cancel" buttons go into, and will handle putting them in the appropriate order. Then put this in the layout you want the buttons in:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="?android:attr/dividerHorizontal"
android:orientation="vertical"
android:showDividers="middle">
<!--- A view, this approach only works with a single view here -->
<your.package.ButtonBar style="?android:attr/buttonBarStyle"
android:id="@+id/buttons"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="1.0">
<Button style="?android:attr/buttonBarButtonStyle"
android:id="@+id/ok_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:text="@string/ok_button" />
<Button style="?android:attr/buttonBarButtonStyle"
android:id="@+id/cancel_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:text="@string/cancel_button" />
</your.package.ButtonBar>
</LinearLayout>
This gives you the look of the dialog with borderless buttons. You can find these attributes in the res in the framework. buttonBarStyle
does the vertical divider and padding. buttonBarButtonStyle
is set as borderlessButtonStyle
for Holo theme, but I believe this should be the most robust way for displaying it as the framework wants to display it.
The answer is that you have to use TableRow.LayoutParams, not LinearLayout.LayoutParams or any other LayoutParams.
TextView tv = new TextView(v.getContext());
LayoutParams params = new TableRow.LayoutParams(0, LayoutParams.WRAP_CONTENT, 1f);
tv.setLayoutParams(params);
The different LayoutParams are not interchangeable and if you use the wrong one then nothing seems to happen. The text view's parent is a table row, hence:
http://developer.android.com/reference/android/widget/TableRow.LayoutParams.html
Have a look at View.setVisibility(View.GONE / View.VISIBLE / View.INVISIBLE)
.
From the API docs:
public void setVisibility(int visibility)
Since: API Level 1
Set the enabled state of this view.
Related XML Attributes: android:visibilityParameters:
visibility
One of VISIBLE, INVISIBLE, or GONE.
Note that LinearLayout
is a ViewGroup
which in turn is a View
. That is, you may very well call, for instance, myLinearLayout.setVisibility(View.VISIBLE)
.
This makes sense. If you have any experience with AWT/Swing, you'll recognize it from the relation between Container
and Component
. (A Container
is a Component
.)
I don't know if anyone is still reading this thread or not, but Jeff's solution will only get you halfway there (kinda literally). What his onMeasure will do is display half the image in half the parent. The problem is that calling super.onMeasure prior to the setMeasuredDimension
will measure all the children in the view based on the original size, then just cut the view in half when the setMeasuredDimension
resizes it.
Instead, you need to call setMeasuredDimension
(as required for an onMeasure override) and provide a new LayoutParams
for your view, then call super.onMeasure
. Remember, your LayoutParams
are derived from your view's parent type, not your view's type.
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
int parentWidth = MeasureSpec.getSize(widthMeasureSpec);
int parentHeight = MeasureSpec.getSize(heightMeasureSpec);
this.setMeasuredDimension(parentWidth/2, parentHeight);
this.setLayoutParams(new *ParentLayoutType*.LayoutParams(parentWidth/2,parentHeight));
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
I believe the only time you'll have problems with the parent LayoutParams
is if the parent is an AbsoluteLayout
(which is deprecated but still sometimes useful).
You'll want to use a number of layout managers to help you achieve the basic results you want.
Check out A Visual Guide to Layout Managers for a comparision.
You could use a GridBagLayout
but that's one of the most complex (and powerful) layout managers available in the JDK.
You could use a series of compound layout managers instead.
I'd place the graphics component and text area on a single JPanel
, using a BorderLayout
, with the graphics component in the CENTER
and the text area in the SOUTH
position.
I'd place the text field and button on a separate JPanel
using a GridBagLayout
(because it's the simplest I can think of to achieve the over result you want)
I'd place these two panels onto a third, master, panel, using a BorderLayout
, with the first panel in the CENTER
and the second at the SOUTH
position.
But that's me
This is the complete basic structure for 100% width layout in Bootstrap v3.0.0. You shouldn't wrap your <div class="row">
with container
class. Cause container
class will take lots of margin and this will not provide you full screen (100% width) layout where bootstrap has removed container-fluid class from their mobile-first version v3.0.0.
So just start writing <div class="row">
without container class and you are ready to go with 100% width layout.

Reply me if you need more further assistance. Thanks.
Although the code isn't perfectly semantic, I think it's more straightforward to have what I call a "clearing div" at the bottom of every container with floats in it. In fact, I've included the following style rule in my reset block for every project:
.clear
{
clear: both;
}
If you're styling for IE6 (god help you), you might want to give this rule a 0px line-height and height as well.
The first line would consist of 3 <div>
s. One outer that contains two inner <div>
s. The first inner <div>
would have float:left
which would make sure it stays to the left, the second would have float:right
, which would stick it to the right.
<div style="width:500;height:50"><br>
<div style="float:left" >stuff </div><br>
<div style="float:right" >stuff </div>
... obviously the inline-styling isn't the best idea - but you get the point.
2,3, and 4 would be single <div>
s.
5 would work like 1.
to remove the height:
$('div#someDiv').css('height', '');
$('div#someDiv').css('height', null);
like John pointed out, set height to auto
:
$('div#someDiv').css('height', 'auto');
(checked with jQuery 1.4)
Step 1: Define bg_layout.xml in drawables folder.
Step 2: Add bg_layout.xml as background to your layout.
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid
android:color="#EEEEEE"/> <!--your desired colour for solid-->
<stroke
android:width="3dp"
android:color="#EEEEEE" /> <!--your desired colour for border-->
<corners
android:radius="50dp"/> <!--shape rounded value-->
</shape>
To offer an update on the situation on Q2 of 2017.
A new CSS3 display property is available in Firefox 53, Chrome 58 and Opera 45.
.clearfix {
display: flow-root;
}
Check the availability for any browser here: http://caniuse.com/#feat=flow-root
The element (with a display property set to flow-root) generates a block container box, and lays out its contents using flow layout. It always establishes a new block formatting context for its contents.
Meaning that if you use a parent div containing one or several floating children, this property is going to ensure the parent encloses all of its children. Without any need for a clearfix hack. On any children, nor even a last dummy element (if you were using the clearfix variant with :before on the last children).

**it one of doing with view **
Just change the theme in the design view of your activity to NoActionBar like the one here
Well, I figured it out myself, right after posting, which is the most embarassing way. :)
It seems every member of a StackPanel will simply fill its minimum requested size.
In the DockPanel, I had docked things in the wrong order. If the TextBox or ListBox is the only docked item without an alignment, or if they are the last added, they WILL fill the remaining space as wanted.
I would love to see a more elegant method of handling this, but it will do.
Since div's by default are block
elements - meaning they will occupy full available width, try using -
display:inline-block;
The div
is now rendered inline i.e. does not disrupt flow of elements, but will still be treated as a block element.
I find this technique easier than wrestling with float
s.
See this tutorial for more - http://learnlayout.com/inline-block.html. I would recommend even the previous articles that lead up to that one. (No, I did not write it)
You cannot exit your application. Using android.finish()
won't exit
the application, it just kills the activity. It's used when we don't
want to see the previous activity on back button click. The
application automatically exits when you switch off the device. The
Android architecture does not support exiting the app. If you want,
you can forcefully exit the app, but that's not considered good
practice.
You could put a _ViewStart.cshtml
file inside the /Views/Public
folder which would override the default one in the /Views
folder and specify the desired layout:
@{
Layout = "~/Views/Shared/_PublicLayout.cshtml";
}
By analogy you could put another _ViewStart.cshtml
file inside the /Views/Staff
folder with:
@{
Layout = "~/Views/Shared/_StaffLayout.cshtml";
}
You could also specify which layout should be used when returning a view inside a controller action but that's per action:
return View("Index", "~/Views/Shared/_StaffLayout.cshtml", someViewModel);
Yet another possibility is a custom action filter which would override the layout. As you can see many possibilities to achieve this. Up to you to choose which one fits best in your scenario.
UPDATE:
As requested in the comments section here's an example of an action filter which would choose a master page:
public class LayoutInjecterAttribute : ActionFilterAttribute
{
private readonly string _masterName;
public LayoutInjecterAttribute(string masterName)
{
_masterName = masterName;
}
public override void OnActionExecuted(ActionExecutedContext filterContext)
{
base.OnActionExecuted(filterContext);
var result = filterContext.Result as ViewResult;
if (result != null)
{
result.MasterName = _masterName;
}
}
}
and then decorate a controller or an action with this custom attribute specifying the layout you want:
[LayoutInjecter("_PublicLayout")]
public ActionResult Index()
{
return View();
}
I put together a little test here:
\documentclass[10pt,twocolumn]{article}
\title{Article Title}
\author{
First Author\\
Department\\
school\\
email@edu
\and
Second Author\\
Department\\
school\\
email@edu
\and
Third Author\\
Department\\
school\\
email@edu
\and
Fourth Author\\
Department\\
school\\
email@edu
}
\date{\today}
\begin{document}
\maketitle
\begin{abstract}
\ldots
\end{abstract}
\section{Introduction}
\ldots
\end{document}
Things to note, the title, author and date fields are declared before \begin{document}
. Also, the multicol package is likely unnecessary in this case since you have declared twocolumn
in the document class.
This example puts all four authors on the same line, but if your authors have longer names, departments or emails, this might cause it to flow over onto another line. You might be able to change the font sizes around a little bit to make things fit. This could be done by doing something like {\small First Author}
. Here's a more detailed article on \LaTeX
font sizes:
https://engineering.purdue.edu/ECN/Support/KB/Docs/LaTeXChangingTheFont
To italicize you can use {\it First Name}
or \textit{First Name}
.
Be careful though, if the document is meant for publication often times journals or conference proceedings have their own formatting guidelines so font size trickery might not be allowed.
In the linearLayout set the WeightSum=2;
And distribute the weight to its childs as you want them to display.. I have given weight ="1" to the child .So both will distribute half of the total.
<LinearLayout
android:id="@+id/linear1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="2"
android:orientation="horizontal" >
<ImageView
android:id="@+id/ring_oss"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="@drawable/ring_oss" />
<ImageView
android:id="@+id/maila_oss"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="@drawable/maila_oss" />
</LinearLayout>
try this
#center_div
{
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
You need to try one of the following:
They offer many more features and will be easier to get what you are looking for.
This work for me:
yourview.setBackground(null);
android.R.layout.simple_list_item_1
, this is row layout file in your res/layout folder which contains the corresponding design for your row in listview
. Now we just bind the array list items to the row layout by using mylistview.setadapter(aa)
;
You can try to add this attribute dynamically, by putting the following code in the onCreate
method of your activity:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
This worked for me, but that:
android:windowSoftInputMode="adjustPan"
didnt.
fill_parent
will make the width or height of the element to be as
large as the parent element, in other words, the container.
wrap_content
will make the width or height be as large as needed to
contain the elements within it.
To show a simple star rating in round figure just use this code
public static String getIntToStar(int starCount) {
String fillStar = "\u2605";
String blankStar = "\u2606";
String star = "";
for (int i = 0; i < starCount; i++) {
star = star.concat(" " + fillStar);
}
for (int j = (5 - starCount); j > 0; j--) {
star = star.concat(" " + blankStar);
}
return star;
}
And use it like this
button.setText(getIntToStar(4));
UIView's also have a center
property. If you just want to move the position rather than resize, you can just change that - eg:
aView.center = CGPointMake(50, 200);
Otherwise you would do it the way you posted.
1 - remove the margin from your BODY CSS.
2 - wrap all of your html in a wrapper <div id="wrapper"> ... all your body content </div>
3 - Define the CSS for the wrapper:
This will hold everything together, centered on the page.
#wrapper {
margin-left:auto;
margin-right:auto;
width:960px;
}
Use getMeasuredWidth() and getMeasuredHeight() for your view.
Try width: max-content
to adjust the width of the div by it's content.
<!DOCTYPE html>
<html>
<head>
<style>
div.ex1 {
width:500px;
margin: auto;
border: 3px solid #73AD21;
}
div.ex2 {
width: max-content;
margin: auto;
border: 3px solid #73AD21;
}
</style>
</head>
<body>
<div class="ex1">This div element has width 500px;</div>
<br>
<div class="ex2">Width by content size</div>
</body>
</html>
<TextView
android:id="@+id/line"
style="?android:attr/listSeparatorTextViewStyle"
android:paddingTop="5dip"
android:gravity="center_horizontal"
android:layout_below="@+id/connect_help"
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#000" />
Aside from the clear: both
hack, you can skip the extra element and use overflow: hidden
on the wrapping div
:
<div style="overflow: hidden;">
<div style="float: left;"></div>
<div style="float: left;"></div>
</div>
Try this
String mess = getResources().getString(R.string.mess_1);
UPDATE
String string = getString(R.string.hello);
You can use either getString(int)
or getText(int)
to retrieve a string. getText(int)
will retain any rich text styling applied to the string.

I've used flex-grow
property to achieve this goal. You'll have to set display: flex
for parent container, then you need to set flex-grow: 1
for the block you want to fill remaining space, or just flex: 1
as tanius mentioned in the comments.
JPanel testPanel = new JPanel();
testPanel.setLayout(new BoxLayout(testPanel, BoxLayout.Y_AXIS));
/*add variables here and add them to testPanel
e,g`enter code here`
testPanel.add(nameLabel);
testPanel.add(textName);
*/
testPanel.setVisible(true);
try:
Activity parentActivity = this.getParent();
if (parentActivity != null)
{
View landmarkEditNameView = (EditText) parentActivity.findViewById(R.id. landmark_name_dialog_edit);
}
Found the flex magic.
Here's an example of how to do a fixed header and a scrollable content. Code:
<!DOCTYPE html>
<html style="height: 100%">
<head>
<meta charset=utf-8 />
<title>Holy Grail</title>
<!-- Reset browser defaults -->
<link rel="stylesheet" href="reset.css">
</head>
<body style="display: flex; height: 100%; flex-direction: column">
<div>HEADER<br/>------------
</div>
<div style="flex: 1; overflow: auto">
CONTENT - START<br/>
<script>
for (var i=0 ; i<1000 ; ++i) {
document.write(" Very long content!");
}
</script>
<br/>CONTENT - END
</div>
</body>
</html>
* The advantage of the flex solution is that the content is independent of other parts of the layout. For example, the content doesn't need to know height of the header.
For a full Holy Grail implementation (header, footer, nav, side, and content), using flex display, go to here.
It´s simple You set the minWidth or minHeight, depends on what you are looking for, horizontal or vertical. And for the other object(the one that you want to fill the remaining space) you set a weight of 1 (set the width to wrap it´s content), So it will fill the rest of area.
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center|left"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:layout_width="80dp"
android:layout_height="fill_parent"
android:minWidth="80dp" >
</LinearLayout>
In general, you can add a View in a specific position using a FrameLayout as container by specifying the leftMargin and topMargin attributes.
The following example will place a 20x20px ImageView at position (100,200) using a FrameLayout as fullscreen container:
XML
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/root"
android:background="#33AAFF"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
Activity / Fragment / Custom view
//...
FrameLayout root = (FrameLayout)findViewById(R.id.root);
ImageView img = new ImageView(this);
img.setBackgroundColor(Color.RED);
//..load something inside the ImageView, we just set the background color
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(20, 20);
params.leftMargin = 100;
params.topMargin = 200;
root.addView(img, params);
//...
This will do the trick because margins can be used as absolute (X,Y) coordinates without a RelativeLayout:
To support older version Space can be replaced with View as below. Add this view between after left most component and before right most component. This view with weight=1 will stretch and fill the space
<View
android:layout_width="0dp"
android:layout_height="20dp"
android:layout_weight="1" />
Complete sample code is given here. It has has 4 components. Two arrows will be on the right and left side. The Text and Spinner will be in the middle.
<ImageButton
android:id="@+id/btnGenesis"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|center_vertical"
android:layout_marginBottom="2dp"
android:layout_marginLeft="0dp"
android:layout_marginTop="2dp"
android:background="@null"
android:gravity="left"
android:src="@drawable/prev" />
<View
android:layout_width="0dp"
android:layout_height="20dp"
android:layout_weight="1" />
<TextView
android:id="@+id/lblVerseHeading"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:gravity="center"
android:textSize="25sp" />
<Spinner
android:id="@+id/spinnerVerses"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:gravity="center"
android:textSize="25sp" />
<View
android:layout_width="0dp"
android:layout_height="20dp"
android:layout_weight="1" />
<ImageButton
android:id="@+id/btnExodus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|center_vertical"
android:layout_marginBottom="2dp"
android:layout_marginLeft="0dp"
android:layout_marginTop="2dp"
android:background="@null"
android:gravity="right"
android:src="@drawable/next" />
</LinearLayout>
It's really easy. Try the code below,
<RelativeLayout
android:id="@+id/second_RL"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/first_RL"
android:background="@android:color/holo_blue_bright"
android:gravity="center">
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</RelativeLayout>

<div id="content">
<iframe src="http://www.microsoft.com" name="frame2" id="frame2" frameborder="0" marginwidth="0" marginheight="0" scrolling="auto" onload="" allowtransparency="false"></iframe>
</div>
<div id="block"></div>
<div id="header"></div>
<div id="footer"></div>
Relevant parts of CSS:
div#content {
position: fixed;
top: 80px;
left: 40px;
bottom: 25px;
min-width: 200px;
width: 40%;
background: black;
}
div#content iframe {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
height: 100%;
width: 100%;
}
You've almost done it. However setting flex: 0 0 <basis>
declaration to the columns would prevent them from growing/shrinking; And the <basis>
parameter would define the width of columns.
In addition, you could use CSS3 calc()
expression to specify the height
of columns with the respect to the height of the header.
#productShowcaseTitle {
flex: 0 0 100%; /* Let it fill the entire space horizontally */
height: 100px;
}
#productShowcaseDetail,
#productShowcaseThumbnailContainer {
height: calc(100% - 100px); /* excluding the height of the header */
}
#productShowcaseContainer {_x000D_
display: flex;_x000D_
flex-flow: row wrap;_x000D_
_x000D_

Alternatively, if you could change your markup e.g. wrapping the columns by an additional <div>
element, it would be achieved without using calc()
as follows:
<div class="contentContainer"> <!-- Added wrapper -->
<div id="productShowcaseDetail"></div>
<div id="productShowcaseThumbnailContainer"></div>
</div>
#productShowcaseContainer {
display: flex;
flex-direction: column;
height: 600px; width: 580px;
}
.contentContainer { display: flex; flex: 1; }
#productShowcaseDetail { flex: 3; }
#productShowcaseThumbnailContainer { flex: 2; }
#productShowcaseContainer {_x000D_

Modules Preconditions:
The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (
precondition="managedHandler"
) only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />
If you remove the attribute
precondition="managedHandler"
, Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "
managedHandler
" precondition.To enable all managed modules to run for all requests without configuring each module entry to remove the "
managedHandler
" precondition, use therunAllManagedModulesForAllRequests
property in the<modules>
section:<modules runAllManagedModulesForAllRequests="true" />
When you use this property, the "
managedHandler
" precondition has no effect and all managed modules run for all requests.

I also suggest using contourf(Z)
. For my problem, I wanted to visualize a 3D histogram in 2D, but the contours were too smooth to represent a top view of histogram bars.
So in my case, I prefer to use jucestain's answer. The default shading faceted
of pcolor()
is more suitable.
However, pcolor()
does not use the last row and column of the plotted matrix. For this, I used the padarray()
function:
pcolor(padarray(Z,[1 1],0,'post'))
Sorry if that is not really related to the original post
If you knew that the length of conditions you would care about would all be the same length then you could:
switch(mystring.substring(0, Math.Min(3, mystring.Length))
{
case "abc":
//do something
break;
case "xyz":
//do something else
break;
default:
//do a different thing
break;
}
The Math.Min(3, mystring.Length)
is there so that a string of less than 3 characters won't throw an exception on the sub-string operation.
There are extensions of this technique to match e.g. a bunch of 2-char strings and a bunch of 3-char strings, where some 2-char comparisons matching are then followed by 3-char comparisons. Unless you've a very large number of such strings though, it quickly becomes less efficient than simple if-else chaining for both the running code and the person who has to maintain it.
Edit: Added since you've now stated they will be of different lengths. You could do the pattern I mentioned of checking the first X chars and then the next Y chars and so on, but unless there's a pattern where most of the strings are the same length this will be both inefficient and horrible to maintain (a classic case of premature pessimisation).
The command pattern is mentioned in another answer, so I won't give details of that, as is that where you map string patterns to IDs, but they are option.
I would not change from if-else chains to command or mapping patterns to gain the efficiency switch sometimes has over if-else, as you lose more in the comparisons for the command or obtaining the ID pattern. I would though do so if it made code clearer.
A chain of if-else's can work pretty well, either with string comparisons or with regular expressions (the latter if you have comparisons more complicated than the prefix-matches so far, which would probably be simpler and faster, I'm mentioning reg-ex's just because they do sometimes work well with more general cases of this sort of pattern).
If you go for if-elses, try to consider which cases are going to happen most often, and make those tests happen before those for less-common cases (though of course if "starts with abcd" is a case to look for it would have to be checked before "starts with abc").
OK ! it works for the click event :
$("#submit").click(function(e){
e.preventDefault();
-> block the click of the sumbit ... do what you want
$("#submit").unbind('click').click(); // the html click submit work now !
});
SELECT c1, c2, c3, ... INTO @v1, @v2, @v3,... FROM table_name WHERE condition;

Oracle optimizer chooses join order of tables for inner join. Optimizer chooses the join order of tables only in simple FROM clauses . U can check the oracle documentation in their website. And for the left, right outer join the most voted answer is right. The optimizer chooses the optimal join order as well as the optimal index for each table. The join order can affect which index is the best choice. The optimizer can choose an index as the access path for a table if it is the inner table, but not if it is the outer table (and there are no further qualifications).
The optimizer chooses the join order of tables only in simple FROM clauses. Most joins using the JOIN keyword are flattened into simple joins, so the optimizer chooses their join order.
The optimizer does not choose the join order for outer joins; it uses the order specified in the statement.
When selecting a join order, the optimizer takes into account: The size of each table The indexes available on each table Whether an index on a table is useful in a particular join order The number of rows and pages to be scanned for each table in each join order

Declare you integer variable as nullable

Yes, Use jspdf To create a pdf file.
You can then turn it into a data URI and inject a download link into the DOM
You will however need to write the HTML to pdf conversion yourself.
Just use printer friendly versions of your page and let the user choose how he wants to print the page.
Edit: Apparently it has minimal support
So the answer is write your own PDF writer or get a existing PDF writer to do it for you (on the server).
You can use this equivalent syntax:
obj[name] = value
What you're after is filter
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter
This will allow you to do the following:
var ary = ['three', 'seven', 'eleven'];
var aryWithoutSeven = ary.filter(function(value) { return value != 'seven' });
console.log(aryWithoutSeven); // returns ['three', 'eleven']
This was also noted in this thread somewhere else: https://stackoverflow.com/a/20827100/293492
setContentView(R.layout.avtivity_next);
I think this line of code should be moved to the next activity...
You can use this code:
// Create an array that matches any country to its id (as String):
String[][] countriesId = new String[NUMBER_OF_COUNTRIES_SUPPORTED][];
// Initialize the array, where the first column will be the country's name (in uppercase) and the second column will be its id (as String):
countriesId[0] = new String[] {"US", String.valueOf(R.drawable.us)};
countriesId[1] = new String[] {"FR", String.valueOf(R.drawable.fr)};
// and so on...
// And after you get the variable "countryCode":
int i;
for(i = 0; i<countriesId.length; i++) {
if(countriesId[i][0].equals(countryCode))
break;
}
// Now "i" is the index of the country
img.setImageResource(Integer.parseInt(countriesId[i][1]));
OK, you should apply something like this to your dataset. Do not replace & save or you'll destroy your data! And, btw, you should (almost) never remove outliers from your data:
remove_outliers <- function(x, na.rm = TRUE, ...) {
qnt <- quantile(x, probs=c(.25, .75), na.rm = na.rm, ...)
H <- 1.5 * IQR(x, na.rm = na.rm)
y <- x
y[x < (qnt[1] - H)] <- NA
y[x > (qnt[2] + H)] <- NA
y
}
To see it in action:
set.seed(1)
x <- rnorm(100)
x <- c(-10, x, 10)
y <- remove_outliers(x)
## png()
par(mfrow = c(1, 2))
boxplot(x)
boxplot(y)
## dev.off()
And once again, you should never do this on your own, outliers are just meant to be! =)
EDIT: I added na.rm = TRUE
as default.
EDIT2: Removed quantile
function, added subscripting, hence made the function faster! =)
If you want to see the contents of RDD then yes collect is one option, but it fetches all the data to driver so there can be a problem
<rdd.name>.take(<num of elements you want to fetch>)
Better if you want to see just a sample
Running foreach and trying to print, I dont recommend this because if you are running this on cluster then the print logs would be local to the executor and it would print for the data accessible to that executor. print statement is not changing the state hence it is not logically wrong. To get all the logs you will have to do something like
**Pseudocode**
collect
foreach print
But this may result in job failure as collecting all the data on driver may crash it. I would suggest using take command or if u want to analyze it then use sample collect on driver or write to file and then analyze it.
I think the commands you are looking for are:
cd repo2
git checkout master
git remote add r1remote **url-of-repo1**
git fetch r1remote
git merge r1remote/master --allow-unrelated-histories
git remote rm r1remote
After that repo2/master
will contain everything from repo2/master
and repo1/master
, and will also have the history of both of them.
While you can call exit()
(and may need to do so if your application encounters some fatal error), the cleanest way to exit a program is to return from main()
:
int main()
{
// do whatever your program does
} // function returns and exits program
When you call exit()
, objects with automatic storage duration (local variables) are not destroyed before the program terminates, so you don't get proper cleanup. Those objects might need to clean up any resources they own, persist any pending state changes, terminate any running threads, or perform other actions in order for the program to terminate cleanly.
You can try to do my answer,
you wrote this:
<?php
foreach($group_membership as $i => $username) {
$items = array($username);
}
print_r($items);
?>
And in your case I would do this:
<?php
$items = array();
foreach ($group_membership as $username) { // If you need the pointer (but I don't think) you have to add '$i => ' before $username
$items[] = $username;
} ?>
As you show in your question it seems that you need an array of usernames that are in a particular group :) In this case I prefer a good sql query with a simple while loop ;)
<?php
$query = "SELECT `username` FROM group_membership AS gm LEFT JOIN users AS u ON gm.`idUser` = u.`idUser`";
$result = mysql_query($query);
while ($record = mysql_fetch_array($result)) { \
$items[] = $username;
}
?>
while
is faster, but the last example is only a result of an observation. :)
The process of assembling tree nodes is similar to the process of assembling lists. We have a constructor for tree nodes that initializes the instance variables.
public Tree (Object cargo, Tree left, Tree right) {
this.cargo = cargo;
this.left = left;
this.right = right;
}
We allocate the child nodes first:
Tree left = new Tree (new Integer(2), null, null);
Tree right = new Tree (new Integer(3), null, null);
We can create the parent node and link it to the children at the same time:
Tree tree = new Tree (new Integer(1), left, right);

SQLite out-of-the-box is not really feature-full regarding concurrency. You will get into trouble if you have hundreds of web requests hitting the same SQLite database.
You should definitely go with MySQL or PostgreSQL.
If it is for a single-person project, SQLite will be easier to setup though.
I think you need something like this....
b="HELLO,THERE,WORLD"
re.findall('[\w]+',b)
Which in Python3 will return
['HELLO', 'THERE', 'WORLD']
enum NumberError: Error {
case NegativeNumber(number: Int)
case ZeroNumber
case OddNumber(number: Int)
}
extension NumberError: CustomStringConvertible {
var description: String {
switch self {
case .NegativeNumber(let number):
return "Negative number \(number) is Passed."
case .OddNumber(let number):
return "Odd number \(number) is Passed."
case .ZeroNumber:
return "Zero is Passed."
}
}
}
func validateEvenNumber(_ number: Int) throws ->Int {
if number == 0 {
throw NumberError.ZeroNumber
} else if number < 0 {
throw NumberError.NegativeNumber(number: number)
} else if number % 2 == 1 {
throw NumberError.OddNumber(number: number)

Now Validate Number :
do {
let number = try validateEvenNumber(0)
print("Valid Even Number: \(number)")
} catch let error as NumberError {
print(error.description)

Atlassian posted a good explanation about Continuous integration vs. continuous delivery vs. continuous deployment.
In a nutshell:
Continuous Integration - is an automation to build and test application whenever new commits are pushed into the branch.
Continuous Delivery - is Continuous Integration + Deploy application to production by "clicking on a button" (Release to customers is often, but on demand).
Continuous Deployment - is Continuous Delivery but without human intervention (Release to customers is on-going).
The volatile
and transient
modifiers can be applied to fields of classes1 irrespective of field type. Apart from that, they are unrelated.
The transient
modifier tells the Java object serialization subsystem to exclude the field when serializing an instance of the class. When the object is then deserialized, the field will be initialized to the default value; i.e. null
for a reference type, and zero or false
for a primitive type. Note that the JLS (see 8.3.1.3) does not say what transient
means, but defers to the Java Object Serialization Specification. Other serialization mechanisms may pay attention to a field's transient
-ness. Or they may ignore it.
(Note that the JLS permits a static
field to be declared as transient
. This combination doesn't make sense for Java Object Serialization, since it doesn't serialize statics anyway. However, it could make sense in other contexts, so there is some justification for not forbidding it outright.)
The volatile
modifier tells the JVM that writes to the field should always be synchronously flushed to memory, and that reads of the field should always read from memory. This means that fields marked as volatile can be safely accessed and updated in a multi-thread application without using native or standard library-based synchronization. Similarly, reads and writes to volatile fields are atomic. (This does not apply to >>non-volatile<< long
or double
fields, which may be subject to "word tearing" on some JVMs.) The relevant parts of the JLS are 8.3.1.4, 17.4 and 17.7.
1 - But not to local variables or parameters.
If you're able to make a stored procedure, it could take an array of values, and you could just call that.
Use this simple command:
ng g c users/userlist
users

When using lombok on a fresh installation of Eclipse or STS, you have to:
Install the lombok jar which you can get at https://projectlombok.org/download. Run the jar (as Administrator if using windows) and specify the path to your Eclipse/STS installation.
Restart your IDE (Eclipse or STS)
Give some time for eclipse to generate the class files for lombok (Might take a up to 4 mins in some cases)
getPathInfo() sometimes return null. In documentation HttpServletRequest
This method returns null if there was no extra path information.
I need get path to file without context path in Filter and getPathInfo() return me null. So I use another method: httpRequest.getServletPath()
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException
{
HttpServletRequest httpRequest = (HttpServletRequest) request;
HttpServletResponse httpResponse = (HttpServletResponse) response;
String newPath = parsePathToFile(httpRequest.getServletPath());
...
}
Unlike languages that employ 'true' lexical scoping, Python opts to have specific 'namespaces' for variables, whether it be global
, nonlocal
, or local. It could be argued that making developers consciously code with such namespaces in mind is more explicit, thus more understandable. I would argue that such complexities make the language more unwieldy, but I guess it's all down to personal preference.
Here are some examples regarding global
:-
>>> global_var = 5
>>> def fn():
... print(global_var)
...
>>> fn()
5
>>> def fn_2():
... global_var += 2
... print(global_var)
...
>>> fn_2()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in fn_2
UnboundLocalError: local variable 'global_var' referenced before assignment
>>> def fn_3():
... global global_var
... global_var += 2
... print(global_var)
...
>>> fn_3()
7
The same patterns can be applied to nonlocal
variables too, but this keyword is only available to the latter Python versions.
In case you're wondering, nonlocal
is used where a variable isn't global, but isn't within the function definition it's being used. For example, a def
within a def
, which is a common occurrence partially due to a lack of multi-statement lambdas. There's a hack to bypass the lack of this feature in the earlier Pythons though, I vaguely remember it involving the use of a single-element list...
Note that writing to variables is where these keywords are needed. Just reading from them isn't ambiguous, thus not needed. Unless you have inner def
s using the same variable names as the outer ones, which just should just be avoided to be honest.
A simpler way which eliminates checking if the app can open the url.

Since react-native eject is depreciated in 60.3 and I was getting diff errors trying to upgrade form 60.1 to 60.3 regenerating the android folder was not working.
I had to
rm -R node_modules
Then update react-native in package.json to 59.1 (remove package-lock.json)
Run
npm install
react-native eject
This will regenerate your android and ios folders Finally upgrade back to 60.3
react-native upgrade
react-native upgrade while back and 59.1 did not regenerate my android folder so the eject was necessary.
I tried everything on the post but nothing had worked. I then changed the .htaccess snippet that ErJab put up to read:
RewriteRule ^(.*)$ 'folder_name'/index.php/$1 [L]
The above line fixed it for me. where *folder_name* is the magento root folder.
Hope this helps!

Then you can map and query John Doe's shared things in that parallel thingsSharedWithOthers collection.
proprietary: "John Doe"(a document)
things(collection of John's things documents)
thingsSharedWithOthers(collection of John's things being shared with others):
[thingId]:
{who: "[email protected]", when:timestamp}
{who: "[email protected]", when:timestamp}
then set thingsSharedWithOthers
firebase.firestore()
.collection('thingsSharedWithOthers')
.set(
{ [thingId]:{ who: "[email protected]", when: new Date() } },
{ merge: true }
)
I think you should call the super.draw()
method first before you do anything in surfaceView's draw method.
If expecting JSON back, the simplest way to get it:
$data = json_decode($response->getBody()); // returns an object
// OR
$data = json_decode($response->getBody(), true); // returns an array
json_decode()
will automatically cast the body to string
, so there is no need to call getContents()
.
JQuery has actually two ways to set checked status for radio and checkboxes and it depends on whether you are using value attribute in HTML markup or not:
$("[name=myRadio]").val(["myValue"]);
$("#myRadio1").prop("checked", true);
In first case, we specify the entire radio group using name and tell JQuery to find radio to select using val function. The val function takes 1-element array and finds the radio with matching value, set its checked=true. Others with the same name would be deselected. If no radio with matching value found then all will be deselected. If there are multiple radios with same name and value then the last one would be selected and others would be deselected.
If you are not using value attribute for radio then you need to use unique ID to select particular radio in the group. In this case, you need to use prop function to set "checked" property. Many people don't use value attribute with checkboxes so #2 is more applicable for checkboxes then radios. Also note that as checkboxes don't form group when they have same name, you can do $("[name=myCheckBox").prop("checked", true);
for checkboxes.

I'm not so thrilled about the InetAddress.getLocalHost().getHostName()
solution that you can find so many places on the Internet and indeed also here. That method will get you the hostname as seen from a network perspective. I can see two problems with this:
What if the host has multiple network interfaces ? The host may be known on the network by multiple names. The one returned by said method is indeterminate afaik.
What if the host is not connected to any network and has no network interfaces ?
All OS'es that I know of have the concept of naming a node/host irrespective of network. Sad that Java cannot return this in an easy way. This would be the environment variable COMPUTERNAME
on all versions of Windows and the environment variable HOSTNAME
on Unix/Linux/MacOS (or alternatively the output from host command hostname
if the HOSTNAME
environment variable is not available as is the case in old shells like Bourne and Korn).
I would write a method that would retrieve (depending on OS) those OS vars and only as a last resort use the InetAddress.getLocalHost().getHostName()
method. But that's just me.
As others have pointed out the HOSTNAME
environment variable is typically not available to a Java application on Unix/Linux as it is not exported by default. Hence not a reliable method unless you are in control of the clients. This really sucks. Why isn't there a standard property with this information?
Alas, as far as I can see the only reliable way on Unix/Linux would be to make a JNI call to gethostname() or to use Runtime.exec()
to capture the output from the hostname
command. I don't particularly like any of these ideas but if anyone has a better idea I'm all ears. (update: I recently came across gethostname4j which seems to be the answer to my prayers).
I've created a long explanation in another answer on another post. In particular you may want to read it because it attempts to establish some terminology, gives concrete examples of when the InetAddress.getLocalHost().getHostName()
solution will fail, and points to the only safe solution that I know of currently, namely gethostname4j.
It's sad that Java doesn't provide a method for obtaining the computername. Vote for JDK-8169296 if you are able to.
var inp = $("#txt").val();
if(jQuery.trim(inp).length > 0)
{
//do something
}
Removes white space before checking. If the user entered only spaces then this will still work.
The dash is a special character in Bash as noted at http://tldp.org/LDP/abs/html/special-chars.html#DASHREF. So escaping this once just gets you past Bash, but Grep still has it's own meaning to dashes (by providing options).
So you really need to escape it twice (if you prefer not to use the other mentioned answers). The following will/should work
grep \\-X
grep '\-X'
grep "\-X"
One way to try out how Bash passes arguments to a script/program is to create a .sh script that just echos all the arguments. I use a script called echo-args.sh to play with from time to time, all it contains is:
echo $*
I invoke it as:
bash echo-args.sh \-X
bash echo-args.sh \\-X
bash echo-args.sh "\-X"
You get the idea.
Here are conversion method for both ways. this = instance of your class
public string ToXML()
{
using(var stringwriter = new System.IO.StringWriter())
{
var serializer = new XmlSerializer(this.GetType());
serializer.Serialize(stringwriter, this);
return stringwriter.ToString();
}
}
public static YourClass LoadFromXMLString(string xmlText)
{
using(var stringReader = new System.IO.StringReader(xmlText))
{
var serializer = new XmlSerializer(typeof(YourClass ));
return serializer.Deserialize(stringReader) as YourClass ;
}
}
This comes in late but was quite helpful. I am Just posting for future reference

Well, setTimeout
, per its definition, will not hold up the thread. This is desirable, because if it did, it'd freeze the entire UI for the time it was waiting. if you really need to use setTimeout
, then you should be using callback functions:
function myfunction() {
longfunctionfirst(shortfunctionsecond);
}
function longfunctionfirst(callback) {
setTimeout(function() {
alert('first function finished');
if(typeof callback == 'function')
callback();
}, 3000);
};
function shortfunctionsecond() {
setTimeout('alert("second function finished");', 200);
};
If you are not using setTimeout
, but are just having functions that execute for very long, and were using setTimeout
to simulate that, then your functions would actually be synchronous, and you would not have this problem at all. It should be noted, though, that AJAX requests are asynchronous, and will, just as setTimeout
, not hold up the UI thread until it has finished. With AJAX, as with setTimeout
, you'll have to work with callbacks.
use Try_Convert:Returns a value cast to the specified data type if the cast succeeds; otherwise, returns null.

I create a common init for the designated and required. For convenience inits I delegate to init(frame:)
with frame of zero.
Having zero frame is not a problem because typically the view is inside a ViewController's view; your custom view will get a good, safe chance to layout its subviews when its superview calls layoutSubviews()
or updateConstraints()
. These two functions are called by the system recursively throughout the view hierarchy. You can use either updateContstraints()
or layoutSubviews()
. updateContstraints()
is called first, then layoutSubviews()
. In updateConstraints()
make sure to call super last. In layoutSubviews()
, call super first.
Here's what I do:
@IBDesignable
class MyView: UIView {
convenience init(args: Whatever) {
self.init(frame: CGRect.zero)
//assign custom vars
}
override init(frame: CGRect) {
super.init(frame: frame)
commonInit()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
commonInit()
}
override func prepareForInterfaceBuilder() {
super.prepareForInterfaceBuilder()
commonInit()
}
private func commonInit() {
//custom initialization
}
override func updateConstraints() {
//set subview constraints here
super.updateConstraints()
}
override func layoutSubviews() {
super.layoutSubviews()
//manually set subview frames here
}
}
It is perfectly fine if you want to go with the display: table-cell
solution. But instead of hacking it out, we have a better way to accomplish the same using display: flex;
. flex
is something which has a decent support.
.wrap {_x000D_
height: 200px;_x000D_
width: 200px;_x000D_
border: 1px solid #aaa;_x000D_
margin: 10px;_x000D_
display: flex;_x000D_
}_x000D_
_x000D_
.wrap span {_x000D_
align-self: flex-end;_x000D_
}
_x000D_
<div class="wrap">_x000D_
<span>Align me to the bottom</span>_x000D_
</div>
_x000D_
In the above example, we first set the parent element to display: flex;
and later, we use align-self
to flex-end
. This helps you push the item to the end of the flex
parent.
flex
)If you want to align the text to the bottom, you don't have to write so many properties for that, using display: table-cell;
with vertical-align: bottom;
is enough
div {_x000D_
display: table-cell;_x000D_
vertical-align: bottom;_x000D_
border: 1px solid #f00;_x000D_
height: 100px;_x000D_
width: 100px;_x000D_
}
_x000D_
<div>Hello</div>
_x000D_
Suppose your dataframe is as follows:
>>> df
A B C ID
0 1 3 2 p
1 4 3 2 q
2 4 0 9 r
set_index
to set ID
columns as the dataframe index. df.set_index("ID", drop=True, inplace=True)
orient=index
parameter to have the index as dictionary keys. dictionary = df.to_dict(orient="index")
The results will be as follows:
>>> dictionary
{'q': {'A': 4, 'B': 3, 'D': 2}, 'p': {'A': 1, 'B': 3, 'D': 2}, 'r': {'A': 4, 'B': 0, 'D': 9}}
column_order= ["A", "B", "C"] # Determine your preferred order of columns
d = {} # Initialize the new dictionary as an empty dictionary
for k in dictionary:
d[k] = [dictionary[k][column_name] for column_name in column_order]
I prefer combining DATEADD
and DATEDIFF
functions like this:
GROUP BY DATEADD(MONTH, DATEDIFF(MONTH, 0, Created),0)
Together, these two functions zero-out the date component smaller than the specified datepart (i.e. MONTH
in this example).
You can change the datepart bit to YEAR
, WEEK
, DAY
, etc... which is super handy.
Your original SQL query would then look something like this (I can't test it as I don't have your data set, but it should put you on the right track).
DECLARE @start [datetime] = '2010-04-01';
SELECT
ItemID,
UserID,
DATEADD(MONTH, DATEDIFF(MONTH, 0, Created),0) [Month],
IsPaid,
SUM(Amount)
FROM LIVE L
INNER JOIN Payments I ON I.LiveID = L.RECORD_KEY
WHERE UserID = 16178
AND PaymentDate > @start
One more thing: the Month
column is typed as a DateTime
which is also a nice advantage if you need to further process that data or map it .NET object for example.
You should apply the following styles:
#button:active {
vertical-align: top;
padding: 8px 13px 6px;
}
This will give you the necessary effect, demo here.
To disable resizing completely:
textarea {
resize: none;
}
To allow only vertical resizing:
textarea {
resize: vertical;
}
To allow only horizontal resizing:
textarea {
resize: horizontal;
}
Or you can limit size:
textarea {
max-width: 100px;
max-height: 100px;
}
To limit size to parents width and/or height:
textarea {
max-width: 100%;
max-height: 100%;
}
HTTP transaction, basic access authentication, is not suitable for RBAC, because basic access authentication uses the encrypted username:password every time to identify, while what is needed in RBAC is the Role the user wants to use for a specific call. RBAC does not validate permissions on username, but on roles.
You could tric around to concatenate like this: usernameRole:password, but this is bad practice, and it is also inefficient because when a user has more roles, the authentication engine would need to test all roles in concatenation, and that every call again. This would destroy one of the biggest technical advantages of RBAC, namely a very quick authorization-test.
So that problem cannot be solved using basic access authentication.
To solve this problem, session-maintaining is necessary, and that seems, according to some answers, in contradiction with REST.
That is what I like about the answer that REST should not be treated as a religion. In complex business cases, in healthcare, for example, RBAC is absolutely common and necessary. And it would be a pity if they would not be allowed to use REST because all REST-tools designers would treat REST as a religion.
For me there are not many ways to maintain a session over HTTP. One can use cookies, with a sessionId, or a header with a sessionId.
If someone has another idea I will be glad to hear it.

You want instanceof
:
if (value instanceof Integer)
This will be true even for subclasses, which is usually what you want, and it is also null-safe. If you really need the exact same class, you could do
if (value.getClass() == Integer.class)
or
if (Integer.class.equals(value.getClass())
JackDB, a database client in your web browser, makes this really easy. Especially if you're on Heroku.
It lets you connect to remote databases and run SQL queries on them.
Source
(source: jackdb.com)
Once your DB is connected, you can run a query and export to CSV or TXT (see bottom right).
Note: I'm in no way affiliated with JackDB. I currently use their free services and think it's a great product.
I'm just experimenting with getting my SailsJS app running inside a Docker container to keep my physical machine clean.
I'm using the following command to mount my SailsJS/NodeJS application under /app:
cd my_source_code_folder docker run -it -p 1337:1337 -v $(pwd):/app my_docker/image_with_nodejs_etc
How about something like:
\documentclass{article}
\usepackage{amssymb,amsmath}
\begin{document}
\begin{equation}\label{A_Label}
\begin{split}
w^T x_i + b \geqslant 1-\xi_i \text{ if } y_i &= 1, \\
w^T x_i + b \leqslant -1+\xi_i \text{ if } y_i &= -1
\end{split}
\end{equation}
\end{document}
which produces:
setInterval function is the one that has to be used. Here is an example for the same without any fancy fading option. Simple Javascript that does an image change every 30 seconds. I have assumed that the images were kept in a separate images folder and hence _images/ is present at the beginning of every image. You can have your own path as required to be set.
CODE:
var im = document.getElementById("img");
var images = ["_images/image1.jpg","_images/image2.jpg","_images/image3.jpg"];
var index=0;
function changeImage()
{
im.setAttribute("src", images[index]);
index++;
if(index >= images.length)
{
index=0;
}
}
setInterval(changeImage, 30000);
To do it with an effect like with $.fadeIn() and $.fadeOut() you can use transitions
.visible {
visibility: visible;
opacity: 1;
transition: opacity 1s linear;
}
.hidden {
visibility: hidden;
opacity: 0;
transition: visibility 0s 1s, opacity 1s linear;
}
I prefer using pip in case you are using virtualenv:
apt install libpython2.7 libpython2.7-dev
pip install psycopg2
Calculate the difference between latest date in column A with the date in cell A2.
=MAX(A2:A)-A2
You should use a callback parameter:
function Typer(callback)
{
var srcText = 'EXAMPLE ';
var i = 0;
var result = srcText[i];
var interval = setInterval(function() {
if(i == srcText.length - 1) {
clearInterval(interval);
callback();
return;
}
i++;
result += srcText[i].replace("\n", "<br />");
$("#message").html(result);
},
100);
return true;
}
function playBGM () {
alert("Play BGM function");
$('#bgm').get(0).play();
}
Typer(function () {
playBGM();
});
// or one-liner: Typer(playBGM);
So, you pass a function as parameter (callback
) that will be called in that if
before return
.
Also, this is a good article about callbacks.
function Typer(callback)_x000D_
{_x000D_
var srcText = 'EXAMPLE ';_x000D_

I presume that this question is a continuation of this one.
What are you trying to do? Do you really want to dynamically change the text in your TextView objects when the user clicks a button? You can certainly do that, if you have a reason, but, if the text is static, it is usually set in the main.xml file, like this:
<TextView
android:id="@+id/rate"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/rate"
/>
The string "@string/rate" refers to an entry in your strings.xml file that looks like this:
<string name="rate">Rate</string>
If you really want to change this text later, you can do so by using Nikolay's example - you'd get a reference to the TextView by utilizing the id defined for it within main.xml, like this:
final TextView textViewToChange = (TextView) findViewById(R.id.rate);
textViewToChange.setText(
"The new text that I'd like to display now that the user has pushed a button.");

The answer to this question simply put is: Don't use BOOLEAN with Oracle-- PL/SQL is dumb and it doesn't work. Use another data type to run your process.
A note to SSRS report developers with Oracle datasource: You can use BOOLEAN parameters, but be careful how you implement. Oracle PL/SQL does not play nicely with BOOLEAN, but you can use the BOOLEAN value in the Tablix Filter if the data resides in your dataset. This really tripped me up, because I have used BOOLEAN parameter with Oracle data source. But in that instance I was filtering against Tablix data, not SQL query.
If the data is NOT in your SSRS Dataset Fields, you can rewrite the SQL something like this using an INTEGER parameter:
__
<ReportParameter Name="paramPickupOrders">
<DataType>Integer</DataType>
<DefaultValue>
<Values>
<Value>0</Value>
</Values>
</DefaultValue>
<Prompt>Pickup orders?</Prompt>
<ValidValues>
<ParameterValues>
<ParameterValue>
<Value>0</Value>
<Label>NO</Label>
</ParameterValue>
<ParameterValue>
<Value>1</Value>
<Label>YES</Label>
</ParameterValue>
</ParameterValues>
</ValidValues>
</ReportParameter>
...
<Query>
<DataSourceName>Gmenu</DataSourceName>
<QueryParameters>
<QueryParameter Name=":paramPickupOrders">
<Value>=Parameters!paramPickupOrders.Value</Value>
</QueryParameter>
<CommandText>
where
(:paramPickupOrders = 0 AND ordh.PICKUP_FLAG = 'N'
OR :paramPickupOrders = 1 AND ordh.PICKUP_FLAG = 'Y' )
If the data is in your SSRS Dataset Fields, you can use a tablix filter with a BOOLEAN parameter:
__
</ReportParameter>
<ReportParameter Name="paramFilterOrdersWithNoLoad">
<DataType>Boolean</DataType>
<DefaultValue>
<Values>
<Value>false</Value>
</Values>
</DefaultValue>
<Prompt>Only orders with no load?</Prompt>
</ReportParameter>
...
<Tablix Name="tablix_dsMyData">
<Filters>
<Filter>
<FilterExpression>
=(Parameters!paramFilterOrdersWithNoLoad.Value=false)
or (Parameters!paramFilterOrdersWithNoLoad.Value=true and Fields!LOADNUMBER.Value=0)
</FilterExpression>

<FilterValue DataType="Boolean">=true</FilterValue>

With the last update of Androd Studio I have two versions of the IDE's launcher
One is called studio.exe and the other studio64.exe they are both on:
C:\Users\myUserName\AppData\Local\Android\android-studio\bin
You have to launch the one that matches your Java version 64 or 32 bit
This is the best answer for the way I think, but it would have been nicer in a table:
So, rewording:
You need to use \r
to use a line feed (ASCII 0x0A
, the Unix newline) in a regex replacement, but that is peculiar to the replacement - you should normally continue to expect to use \n
for line feed and \r
for carriage return.
This is because Vim used \n
in a replacement to mean the NIL character (ASCII 0x00
). You might have expected NIL to have been \0
instead, freeing \n
for its usual use for line feed, but \0
already has a meaning in regex replacements, so it was shifted to \n
. Hence then going further to also shift the newline from \n
to \r
(which in a regex pattern is the carriage return character, ASCII 0x0D
).
Character | ASCII code | C representation | Regex match | Regex replacement -------------------------+------------+------------------+-------------+------------------------ nil | 0x00 | \0 | \0 | \n line feed (Unix newline) | 0x0a | \n | \n | \r carriage return | 0x0d | \r | \r | <unknown>
NB: ^M
(Ctrl + V Ctrl + M on Linux) inserts a newline when used in a regex replacement rather than a carriage return as others have advised (I just tried it).
Also note that Vim will translate the line feed character when it saves to file based on its file format settings and that might confuse matters.
SO...older thread, I know, but...
@RoccoMusolino had a nice catch; here's an alternative:
TL;DR:
const intArray = [...("5 6 7 69 foo 0".split(' ').filter(i => /\d/g.test(i)))]
WRONG: "5 6 note this foo".split(" ").map(Number).filter(Boolean); // [5, 6]
There is a subtle flaw in the more elegant solutions listed here, specifically @amillara and @Marcus' otherwise beautiful answers.
The problem occurs when an element of the string array isn't integer-like, perhaps in a case without validation on an input. For a contrived example...
The problem:
var effedIntArray = "5 6 7 69 foo".split(' ').map(Number); // [5, 6, 7, 69, NaN]
Since you obviously want a PURE int array, that's a problem. Honestly, I didn't catch this until I copy-pasted SO code into my script... :/
The (slightly-less-baller) fix:
var intArray = "5 6 7 69 foo".split(" ").map(Number).filter(Boolean); // [5, 6, 7, 69]
So, now even when you have crap int string, your output is a pure integer array. The others are really sexy in most cases, but I did want to offer my mostly rambly w'actually. It is still a one-liner though, to my credit...
Hope it saves someone time!
/* here are two different ways to do this */
//using jquery:
$(document).ready(function(){
$('#link_other a').attr('target', '_blank');
});
// not using jquery
window.onload = function(){
var anchors = document.getElementById('link_other').getElementsByTagName('a');

You could also add a title tag to notify the user that you are doing this, to warn them, because as has been pointed out, it's not what users expect:
$('#link_other a').attr('target', '_blank').attr('title','This link will open in a new window.');
The link to the help page is the same for python 2.6 and as far as I know there was no change in the csv module since 2.5 (besides bug fixes).

Modern CPUs provide a lot of low-level instructions, besides the usual arithmetic and logic, known as extensions, e.g. SSE2, SSE4, AVX, etc. From the Wikipedia:
Advanced Vector Extensions (AVX) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008 and first supported by Intel with the Sandy Bridge processor shipping in Q1 2011 and later on by AMD with the Bulldozer processor shipping in Q3 2011. AVX provides new features, new instructions and a new coding scheme.
In particular, AVX introduces fused multiply-accumulate (FMA) operations, which speed up linear algebra computation, namely dot-product, matrix multiply, convolution, etc. Almost every machine-learning training involves a great deal of these operations, hence will be faster on a CPU that supports AVX and FMA (up to 300%). The warning states that your CPU does support AVX (hooray!).
I'd like to stress here: it's all about CPU only.
Because tensorflow default distribution is built without CPU extensions, such as SSE4.1, SSE4.2, AVX, AVX2, FMA, etc. The default builds (ones from pip install tensorflow
) are intended to be compatible with as many CPUs as possible. Another argument is that even with these extensions CPU is a lot slower than a GPU, and it's expected for medium- and large-scale machine-learning training to be performed on a GPU.
If you have a GPU, you shouldn't care about AVX support, because most expensive ops will be dispatched on a GPU device (unless explicitly set not to). In this case, you can simply ignore this warning by
# Just disables the warning, doesn't take advantage of AVX/FMA to run faster
import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'
... or by setting export TF_CPP_MIN_LOG_LEVEL=2
if you're on Unix. Tensorflow is working fine anyway, but you won't see these annoying warnings.
If you don't have a GPU and want to utilize CPU as much as possible, you should build tensorflow from the source optimized for your CPU with AVX, AVX2, and FMA enabled if your CPU supports them. It's been discussed in this question and also this GitHub issue. Tensorflow uses an ad-hoc build system called bazel and building it is not that trivial, but is certainly doable. After this, not only will the warning disappear, tensorflow performance should also improve.

You might take advantage of ruby's "splat" or flattening syntax.
This makes overgrown when
clauses — you have about 10 values to test per branch if I understand correctly — a little more readable in my opinion. Additionally, you can modify the values to test at runtime. For example:
honda = ['honda', 'acura', 'civic', 'element', 'fit', ...]
toyota = ['toyota', 'lexus', 'tercel', 'rx', 'yaris', ...]
...
if include_concept_cars
honda += ['ev-ster', 'concept c', 'concept s', ...]
...
end
case car
when *toyota
# Do something for Toyota cars
when *honda
# Do something for Honda cars
...
end
Another common approach would be to use a hash as a dispatch table, with keys for each value of car
and values that are some callable object encapsulating the code you wish to execute.
You could wrap window.setTimeout
like this, which I think is similar to what you were suggesting in the question:
var Timer = function(callback, delay) {
var timerId, start, remaining = delay;
this.pause = function() {
window.clearTimeout(timerId);
remaining -= Date.now() - start;
};
this.resume = function() {
start = Date.now();
window.clearTimeout(timerId);
timerId = window.setTimeout(callback, remaining);
};
this.resume();
};
var timer = new Timer(function() {
alert("Done!");
}, 1000);
timer.pause();
// Do some stuff...
timer.resume();
I assume 0
means false
(which is the case in a lot of programming languages). That means true
is not 0
(some languages use -1
some others use 1
; doesn't hurt to be compatible to either). So assuming by "better" you mean less typing, you can just write:
bool boolValue = intValue != 0;
I agree with SLaks, but here you go
<asp:HyperLink id="hyperlink1"
NavigateUrl="#"
Text=""
runat="server"/>
or you can alter the href using
hyperlink1.NavigateUrl = "#";
hyperlink1.Text = string.empty;
In Windows 8 and up there's a way to enable the feature from the command line without having to download/install anything explicitly by running the following:
dism /online /Enable-Feature:Windows-Identity-Foundation
And then find the file by running the following at the root of your Windows disk:
dir /s /b Microsoft.IdentityModel.dll
Also, GitHub pages doesn't currently support Git LFS. As such, if you have images (or other binary assets) in GitHub pages committed with Git LFS, you'll get 404 not found for those files.
This will be quite common for documentation generated with Doxygen or similar tool.
The solution in this case is to simply not commit those files with Git LFS.
Note that your initial query is probably not returning what you want:
SELECT availables.bookdate AS Date, DATEDIFF(now(),availables.updated_at) as Age
FROM availables INNER JOIN rooms ON availables.room_id=rooms.id
WHERE availables.bookdate BETWEEN '2009-06-25' AND date_add('2009-06-25', INTERVAL 4 DAY) AND rooms.hostel_id = 5094 GROUP BY availables.bookdate
You are grouping by book date, but you are not using any grouping function on the second column of your query.
The query you are probably looking for is:
SELECT availables.bookdate AS Date, count(*) as subtotal, sum(DATEDIFF(now(),availables.updated_at) as Age)
FROM availables INNER JOIN rooms ON availables.room_id=rooms.id
WHERE availables.bookdate BETWEEN '2009-06-25' AND date_add('2009-06-25', INTERVAL 4 DAY) AND rooms.hostel_id = 5094
GROUP BY availables.bookdate
I know this is old and there are several good solutions already posted, but a simple solution that worked for me is the following CSS
<style>
.divider{
margin: 0cm 0cm .5cm 0cm;
}
</style>
and then create a div in your html
<div class="divider"></div>
You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree
option for single commands, or the GIT_WORK_TREE
environment variable. There is also the core.worktree
configuration option but it will not work in a bare repository (check the man page for what it does).
# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status
This seems to work fine for me: it checks for file existance and creates the file to be sure it's a writable location. Should work fine, you can change it to return directly the FileStream (which is normally what you need for a temp file):
private string GetTempFile(string fileExtension)
{
string temp = System.IO.Path.GetTempPath();
string res = string.Empty;
while (true) {
res = string.Format("{0}.{1}", Guid.NewGuid().ToString(), fileExtension);
res = System.IO.Path.Combine(temp, res);
if (!System.IO.File.Exists(res)) {
try {
System.IO.FileStream s = System.IO.File.Create(res);
s.Close();
break;
}
catch (Exception) {
}
}
}
return res;
} // GetTempFile
Simple solution:
<iframe onload="this.style.height=this.contentWindow.document.body.scrollHeight + 'px';" ...></iframe>
This works when the iframe and parent window are in the same domain. It does not work when the two are in different domains.
The #!
line tells the kernel (specifically, the implementation of the execve
system call) that this program is written in an interpreted language; the absolute pathname that follows identifies the interpreter. Programs compiled to machine code begin with a different byte sequence -- on most modern Unixes, 7f 45 4c 46
(^?ELF) that identifies them as such.
You can put an absolute path to any program you want after the #!
, as long as that program is not itself a #!
script. The kernel rewrites an invocation of
./script arg1 arg2 arg3 ...
where ./script
starts with, say, #! /usr/bin/perl
, as if the command line had actually been
/usr/bin/perl ./script arg1 arg2 arg3
Or, as you have seen, you can use #! /bin/sh
to write a script intended to be interpreted by sh
.
The #!
line is only processed if you directly invoke the script (./script
on the command line); the file must also be executable (chmod +x script
). If you do sh ./script
the #!
line is not necessary (and will be ignored if present), and the file does not have to be executable. The point of the feature is to allow you to directly invoke interpreted-language programs without having to know what language they are written in. (Do grep '^#!' /usr/bin/*
-- you will discover that a great many stock programs are in fact using this feature.)
Here are some rules for using this feature:
#!
must be the very first two bytes in the file. In particular, the file must be in an ASCII-compatible encoding (e.g. UTF-8 will work, but UTF-16 won't) and must not start with a "byte order mark", or the kernel will not recognize it as a #!
script.#!
must be an absolute path (starts with /
). It cannot contain space, tab, or newline characters.#!
and the /
. Do not put more than one space there.#!
line, they will not be expanded.#! /usr/bin/awk -f
), sometimes it's just useful (#! /usr/bin/perl -Tw
). Unfortunately, you cannot put two or more arguments after the absolute path.#! /usr/bin/env interpreter
instead of #! /absolute/path/to/interpreter
. This is almost always a mistake. It makes your program's behavior depend on the $PATH
variable of the user who invokes the script. And not all systems have env
in the first place.setuid
or setgid
privileges can't use #!
; they have to be compiled to machine code. (If you don't know what setuid
is, don't worry about this.)Regarding csh
, it relates to sh
roughly as Nutrimat Advanced Tea Substitute does to tea. It has (or rather had; modern implementations of sh
have caught up) a number of advantages over sh
for interactive usage, but using it (or its descendant tcsh
) for scripting is almost always a mistake. If you're new to shell scripting in general, I strongly recommend you ignore it and focus on sh
. If you are using a csh
relative as your login shell, switch to bash
or zsh
, so that the interactive command language will be the same as the scripting language you're learning.
Not so hard:
#include <thread>
void Test::runMultiThread()
{
std::thread t1(&Test::calculate, this, 0, 10);
std::thread t2(&Test::calculate, this, 11, 20);
t1.join();
t2.join();
}
If the result of the computation is still needed, use a future instead:
#include <future>
void Test::runMultiThread()
{
auto f1 = std::async(&Test::calculate, this, 0, 10);
auto f2 = std::async(&Test::calculate, this, 11, 20);
auto res1 = f1.get();
auto res2 = f2.get();

Yes, you may put comments in there. They however must start at the beginning of a line.
cf. http://git-scm.com/book/en/Git-Basics-Recording-Changes-to-the-Repository#Ignoring-Files

You can use pandas it has some built in functions for comparison. So if you want to select values of "A" that are met by the conditions of "B" and "C" (assuming you want back a DataFrame pandas object)
df[['A']][df.B.gt(50) & df.C.ne(900)]
df[['A']]
will give you back column A in DataFrame format.
pandas 'gt' function will return the positions of column B that are greater than 50 and 'ne' will return the positions not equal to 900.
Follow these steps:

What image do you want to hide? Assuming all images, the following should work:
$("img").hide();
Otherwise, using selectors, you could find all images that are child elements of the containing div, and hide those.

The read_sql
docs say this params
argument can be a list, tuple or dict (see docs).
To pass the values in the sql query, there are different syntaxes possible: ?
, :1
, :name
, %s
, %(name)s
(see PEP249).
But not all of these possibilities are supported by all database drivers, which syntax is supported depends on the driver you are using (psycopg2
in your case I suppose).
In your second case, when using a dict, you are using 'named arguments', and according to the psycopg2
documentation, they support the %(name)s
style (and so not the :name
I suppose), see http://initd.org/psycopg/docs/usage.html#query-parameters.
So using that style should work:
df = psql.read_sql(('select "Timestamp","Value" from "MyTable" '
'where "Timestamp" BETWEEN %(dstart)s AND %(dfinish)s'),
db,params={"dstart":datetime(2014,6,24,16,0),"dfinish":datetime(2014,6,24,17,0)},
index_col=['Timestamp'])

There are several ways to assign the equal variables.
The easiest one:
grade_1 = grade_2 = grade_3 = average = 0.0
With unpacking:
grade_1, grade_2, grade_3, average = 0.0, 0.0, 0.0, 0.0
With list comprehension and unpacking:
>>> grade_1, grade_2, grade_3, average = [0.0 for _ in range(4)]
>>> print(grade_1, grade_2, grade_3, average)
0.0 0.0 0.0 0.0

The $.getJSON()
method is shorthand that does not let you specify advanced options like that. To do that, you need to use the full $.ajax()
method.
Notice in the documentation at http://api.jquery.com/jQuery.getJSON/:
This is a shorthand Ajax function, which is equivalent to:
$.ajax({
url: url,
dataType: 'json',
data: data,
success: callback
});
So just use $.ajax()
and provide all the extra parameters you need.
Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.
So, first build a list, then use pickle.dump
to send it to a file...

if(isset($i) & isset($ip) & isset($a) & isset($b))

$r = mysql_query("SELECT COUNT(*) FROM $db.ban WHERE ip=$ip"); //Check if banned
$r = mysql_fetch_array($r);

Not sure its faster with VBA - the fastest way to do it in the normal Excel programm would be:
Ctrl-G
A1:X50 Enter
Delete
Unless you have to do this very often, entering and then triggering the VBAcode is more effort.
And in case you only want to delete formulas or values, you can insert Ctrl-G, Alt-S
to select Goto Special and here select Formulas or Values.
XHTML solution:
<input type="radio" name="imgsel" value="" checked="checked" />
Please note, that the actual value of checked
attribute does not actually matter; it's just a convention to assign "checked"
. Most importantly, strings like "true"
or "false"
don't have any special meaning.
If you don't aim for XHTML conformance, you can simplify the code to:
<input type="radio" name="imgsel" value="" checked>
You can get the raw data by calling ReadAsStringAsAsync
on the Request.Content
property.
string result = await Request.Content.ReadAsStringAsync();
There are various overloads if you want it in a byte or in a stream. Since these are async-methods you need to make sure your controller is async:
public async Task<IHttpActionResult> GetSomething()
{
var rawMessage = await Request.Content.ReadAsStringAsync();
// ...
return Ok();
}
EDIT: if you're receiving an empty string from this method, it means something else has already read it. When it does that, it leaves the pointer at the end. An alternative method of doing this is as follows:
public IHttpActionResult GetSomething()
{
var reader = new StreamReader(Request.Body);
reader.BaseStream.Seek(0, SeekOrigin.Begin);
var rawMessage = reader.ReadToEnd();
return Ok();
}
In this case, your endpoint doesn't need to be async (unless you have other async-methods)
My use case was to save multiple JSON objects to a file and marty's answer helped me somewhat. But to serve my use case, the answer was not complete as it would overwrite the old data every time a new entry was saved.
To save multiple entries in a file, one must check for the old content (i.e., read before write). A typical file holding JSON data will either have a list
or an object
as root. So I considered that my JSON file always has a list of objects
and every time I add data to it, I simply load the list first, append my new data in it, and dump it back to a writable-only instance of file (w
):
def saveJson(url,sc): # This function writes the two values to the file
newdata = {'url':url,'sc':sc}
json_path = "db/file.json"
old_list= []
with open(json_path) as myfile: # Read the contents first
old_list = json.load(myfile)
old_list.append(newdata)
with open(json_path,"w") as myfile: # Overwrite the whole content
json.dump(old_list, myfile, sort_keys=True, indent=4)
return "success"
The new JSON file will look something like this:
[
{
"sc": "a11",
"url": "www.google.com"
},
{
"sc": "a12",
"url": "www.google.com"
},
{
"sc": "a13",
"url": "www.google.com"
}
]
NOTE: It is essential to have a file named file.json
with []
as initial data for this approach to work
PS: not related to original question, but this approach could also be further improved by first checking if our entry already exists (based on one or multiple keys) and only then append and save the data.
This is how to get the html DOM element purely with JS:
var htmlElement = document.getElementsByTagName("html")[0];
or
var htmlElement = document.querySelector("html");
And if you want to use jQuery to get attributes from it...
$(htmlElement).attr(INSERT-ATTRIBUTE-NAME);
My attempt uses expectimax like other solutions above, but without bitboards. Nneonneo's solution can check 10millions of moves which is approximately a depth of 4 with 6 tiles left and 4 moves possible (2*6*4)4. In my case, this depth takes too long to explore, I adjust the depth of expectimax search according to the number of free tiles left:
depth = free > 7 ? 1 : (free > 4 ? 2 : 3)
The scores of the boards are computed with the weighted sum of the square of the number of free tiles and the dot product of the 2D grid with this:
[[10,8,7,6.5],
[.5,.7,1,3],
[-.5,-1.5,-1.8,-2],
[-3.8,-3.7,-3.5,-3]]
which forces to organize tiles descendingly in a sort of snake from the top left tile.

I know notepad++ has a feature that lets you select blocks of text independent of line/column by holding control + alt + drag. So you can select just about any block of text you want.
Instead of getting all the table columns using * in your sql statement, you use to specify the table columns you need.
You can use the SQL statement something like:
SELECT CONCAT(FIRSTNAME, ' ', LASTNAME) AS FIRSTNAME FROM customer;
BTW, why couldn't you use FullName instead of FirstName? Like this:
SELECT CONCAT(FIRSTNAME, ' ', LASTNAME) AS 'CUSTOMER NAME' FROM customer;
One method is to check scrollTop against itself. Give the content a scroll value larger than its size and then check to see if its scrollTop is 0 or not (if it is not 0, it has overflow.)
You need to put the JavaScript at the end of the body tag.
It doesn't find it because it's not in the DOM yet!
You can also wrap it in the onload event handler like this:
window.onload = function() {
var refButton = document.getElementById( 'btnButton' );
refButton.onclick = function() {
alert( 'I am clicked!' );
}
}
I was running a PowerShell script into the task scheduller but i forgot to enable the execution-policy to unrestricted, in an elevated PowerShell console:
Set-ExecutionPolicy Unrestricted
After that, the error disappeared (0x1).
I know this is an old post but just for reference. Here is how to append without the special case check for an empty list, although at the expense of more complex looking code.
void Append(List * l, Node * n)
{
Node ** next = &list->Head;
while (*next != NULL) next = &(*next)->Next;
*next = n;
n->Next = NULL;
}
You are calling DoDownloadAsync() but you don't wait it. So your program going to the next line. But there is another problem, Async methods should return Task
or Task<T>
, if you return nothing and you want your method will be run asyncronously you should define your method like this:
private static async Task DoDownloadAsync() { WebClient w = new WebClient(); string txt = await w.DownloadStringTaskAsync("http://www.google.com/"); Debug.WriteLine(txt); }
And in Main method you can't await for DoDownloadAsync
, because you can't use await keyword in non-async function, and you can't make Main
async. So consider this:
var result = DoDownloadAsync(); Debug.WriteLine("DoDownload done"); result.Wait();
A quick and dirty way is to use Thread.currentThread().setName(myName);
in the run()
method.
Angelika Langers Secrets of equals gets into that with a long and detailed discussion for a few common and well-known examples, including by Josh Bloch and Barbara Liskov, discovering a couple of problems in most of them. She also gets into the instanceof
vs getClass
. Some quote from it
Conclusions
Having dissected the four arbitrarily chosen examples of implementations of equals() , what do we conclude?
First of all: there are two substantially different ways of performing the check for type match in an implementation of equals() . A class can allow mixed-type comparison between super- and subclass objects by means of the instanceof operator, or a class can treat objects of different type as non-equal by means of the getClass() test. The examples above illustrated nicely that implementations of equals() using getClass() are generally more robust than those implementations using instanceof .
The instanceof test is correct only for final classes or if at least method equals() is final in a superclass. The latter essentially implies that no subclass must extend the superclass's state, but can only add functionality or fields that are irrelevant for the object's state and behavior, such as transient or static fields.
Implementations using the getClass() test on the other hand always comply to the equals() contract; they are correct and robust. They are, however, semantically very different from implementations that use the instanceof test. Implementations using getClass() do not allow comparison of sub- with superclass objects, not even when the subclass does not add any fields and would not even want to override equals() . Such a "trivial" class extension would for instance be the addition of a debug-print method in a subclass defined for exactly this "trivial" purpose. If the superclass prohibits mixed-type comparison via the getClass() check, then the trivial extension would not be comparable to its superclass. Whether or not this is a problem fully depends on the semantics of the class and the purpose of the extension.
With little modification but almost similar approach to get the full file path of each sub folder
dataFolderPath = 'UCR_TS_Archive_2015/';
dirData = dir(dataFolderPath); %# Get the data for the current directory
dirIndex = [dirData.isdir]; %# Find the index for directories
fileList = {dirData(~dirIndex).name}'; %'# Get a list of the files
if ~isempty(fileList)
fileList = cellfun(@(x) fullfile(dataFolderPath,x),... %# Prepend path to files
fileList,'UniformOutput',false);
end
subDirs = {dirData(dirIndex).name}; %# Get a list of the subdirectories
validIndex = ~ismember(subDirs,{'.','..'}); %# Find index of subdirectories
%# that are not '.' or '..'
for iDir = find(validIndex) %# Loop over valid subdirectories
nextDir = fullfile(dataFolderPath,subDirs{iDir}); %# Get the subdirectory path
getAllFiles = dir(nextDir);
for k = 1:1:size(getAllFiles,1)
validFileIndex = ~ismember(getAllFiles(k,1).name,{'.','..'});
if(validFileIndex)
filePathComplete = fullfile(nextDir,getAllFiles(k,1).name);
fprintf('The Complete File Path: %s\n', filePathComplete);
end
end
end
The format
method was introduced in Python 2.6. It is more capable and not much more difficult to use:
>>> "Hello {}, my name is {}".format('john', 'mike')
'Hello john, my name is mike'.
>>> "{1}, {0}".format('world', 'Hello')
'Hello, world'
>>> "{greeting}, {}".format('world', greeting='Hello')
'Hello, world'
>>> '%s' % name
"{'s1': 'hello', 's2': 'sibal'}"
>>> '%s' %name['s1']
'hello'

Are'nt you creating the pdf file but not actually writing the byte array back? Therefore you cannot open the PDF.
out = new FileOutputStream("D:/ABC_XYZ/1.pdf");
out.Write(b, 0, b.Length);
out.Position = 0;
out.Close();
This is in addition to correctly reading in the PDF to byte array.
Custom attributes are supported natively in React 16. This means that adding a custom attribute to an element is now as simple as adding it to a render
function, like so:
render() {
return (
<div custom-attribute="some-value" />
);
}
For more:
https://reactjs.org/blog/2017/09/26/react-v16.0.html#support-for-custom-dom-attributes
https://facebook.github.io/react/blog/2017/09/08/dom-attributes-in-react-16.html
Custom attributes are currently not supported. See this open issue for more info: https://github.com/facebook/react/issues/140
As a workaround, you can do something like this in componentDidMount
:
componentDidMount: function() {
var element = ReactDOM.findDOMNode(this.refs.test);
element.setAttribute('custom-attribute', 'some value');
}
See https://jsfiddle.net/peterjmag/kysymow0/ for a working example. (Inspired by syranide's suggestion in this comment.)
Pandas seem to be recommending df.to_numpy since
the other methods still raise a FutureWarning
: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_numpy.html#pandas.DataFrame.to_numpy
So, an alternative that would work int this case is:
b=a['Names']
c = b.to_numpy().tolist()
if 'Mel' in c:
print("Mel is in the dataframe column Names")
I know this is a late answer, but I hope this will help someone.
Consider that you have defined following classes in a css file 'primary', 'font-i', 'font-xl'
<h3 class = {` ${'primary'} ${'font-i'} font-xl`}> HELLO WORLD </h3>
_x000D_
would do the trick!

You need a new version of notepad++. Looks like old versions don't support |
.
Note: egrep "CAT|TOWN"
will search for lines containing CATOWN. (CAT)|(TOWN)
is the proper or extension (matching 1,3,4). Strangely you wrote and which is btw (CAT.*TOWN)|(TOWN.*CAT)
You may use:
FileSystems.getDefault().getPath(new String()).toAbsolutePath();
or
FileSystems.getDefault().getPath(new String("./")).toAbsolutePath().getParent()
This will give you the root folder path without using the name of the file. You can then drill down to where you want to go.
Example: /src/main/java...
If you want to use pure Ruby (no Rails), don't want to create extension methods (maybe you need this only in one or two places and don't want to pollute namespace with tons of methods) and don't want to edit hash in place (i.e., you're fan of functional programming like me), you can 'select':
>> x = {:a => 1, :b => 2, :c => 3}
=> {:a=>1, :b=>2, :c=>3}
>> x.select{|x| x != :a}
=> {:b=>2, :c=>3}
>> x.select{|x| ![:a, :b].include?(x)}
=> {:c=>3}
>> x
=> {:a=>1, :b=>2, :c=>3}
There is no direct equivalent to mvn exec:java
in gradle, you need to either apply the application
plugin or have a JavaExec
task.
application
pluginActivate the plugin:
plugins {
id 'application'
...
}
Configure it as follows:
application {
mainClassName = project.hasProperty("mainClass") ? getProperty("mainClass") : "NULL"
}
On the command line, write
$ gradle -PmainClass=Boo run
JavaExec
taskDefine a task, let's say execute
:
task execute(type:JavaExec) {
main = project.hasProperty("mainClass") ? getProperty("mainClass") : "NULL"
classpath = sourceSets.main.runtimeClasspath
}
To run, write gradle -PmainClass=Boo execute
. You get
$ gradle -PmainClass=Boo execute
:compileJava
:compileGroovy UP-TO-DATE
:processResources UP-TO-DATE
:classes
:execute
I am BOO!
mainClass
is a property passed in dynamically at command line. classpath
is set to pickup the latest classes.
If you do not pass in the mainClass
property, both of the approaches fail as expected.
$ gradle execute
FAILURE: Build failed with an exception.

I feel like this has been well covered, maybe except for the following:
Simple KEY
/ INDEX
(or otherwise called SECONDARY INDEX
) do increase performance if selectivity is sufficient. On this matter, the usual recommendation is that if the amount of records in the result set on which an index is applied exceeds 20% of the total amount of records of the parent table, then the index will be ineffective. In practice each architecture will differ but, the idea is still correct.
Secondary Indexes (and that is very specific to mysql) should not be seen as completely separate and different objects from the primary key. In fact, both should be used jointly and, once this information known, provide an additional tool to the mysql DBA: in Mysql, indexes embed the primary key. It leads to significant performance improvements, specifically when cleverly building implicit covering indexes such as described there.
If you feel like your data should be UNIQUE
, use a unique index. You may think it's optional (for instance, working it out at application level) and that a normal index will do, but it actually represents a guarantee for Mysql that each row is unique, which incidentally provides a performance benefit.
You can only use FULLTEXT
(or otherwise called SEARCH INDEX
) with Innodb (In MySQL 5.6.4 and up) and Myisam Engines
You can only use FULLTEXT
on CHAR
, VARCHAR
and TEXT
column types
FULLTEXT
index involves a LOT more than just creating an index. There's a bunch of system tables created, a completely separate caching system and some specific rules and optimizations applied. See http://dev.mysql.com/doc/refman/5.7/en/fulltext-restrictions.html and http://dev.mysql.com/doc/refman/5.7/en/innodb-fulltext-index.html
Sometime this happened due to not fond any source like if i want to set a text into a textview from adapter then i should use
textView.setText(""+name);
If you write something like
textView.setText(name);
this will not work and sometime we don't find the resource from the string.xml file then this type of error occur.

The main reason for primary and foreign keys is to enforce data consistency.
A primary key enforces the consistency of uniqueness of values over one or more columns. If an ID column has a primary key then it is impossible to have two rows with the same ID value. Without that primary key, many rows could have the same ID value and you wouldn't be able to distinguish between them based on the ID value alone.
A foreign key enforces the consistency of data that points elsewhere. It ensures that the data which is pointed to actually exists. In a typical parent-child relationship, a foreign key ensures that every child always points at a parent and that the parent actually exists. Without the foreign key you could have "orphaned" children that point at a parent that doesn't exist.
You missed the each=
argument to rep()
:
R> n <- 3
R> rep(1:5, each=n)
[1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5
R>
so your example can be done with a simple
R> rep(1:8, each=20)
There are four ways to create a singleton in Java.
Eager initialization singleton
public class Test {
private static final Test test = new Test();
private Test() {
}
public static Test getTest() {
return test;
}
}
Lazy initialization singleton (thread safe)
public class Test {
private static volatile Test test;
private Test() {
}
public static Test getTest() {
if(test == null) {
synchronized(Test.class) {
if(test == null) {
test = new Test();
}
}
}
return test;
}
}
Bill Pugh singleton with holder pattern (preferably the best one)
public class Test {
private Test() {
}
private static class TestHolder {
private static final Test test = new Test();
}
public static Test getInstance() {
return TestHolder.test;
}
}
Enum singleton
public enum MySingleton {
INSTANCE;
private MySingleton() {
System.out.println("Here");
}
}
This is what I normally do:
float rads = atan2(y, x);
if (y < 0) rads = M_PI*2.f + rads;
float degrees = rads*180.f/M_PI;
As many have already told you:
mainList.get(3);
Be sure to check the ArrayList Javadoc.
Also, be careful with the arrays indices: in Java, the first element is at index 0
. So if you are trying to get the third element, your solution would be mainList.get(2);
I know the original poster has a great answer, but for anyone stumbling on this thread like I have there's an important note from the proposal that I think adds something of value to the discussion here, particularly to concerns in the comments about if the typedef
keyword is going to be marked as deprecated in the future, or removed for being redundant/old:
It has been suggested to (re)use the keyword typedef ... to introduce template aliases:
template<class T> typedef std::vector<T, MyAllocator<T> > Vec;
That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages [sic] among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template;
Vec
is not an alias for a type, and should not be taken for a typedef-name. The nameVec
is a name for the familystd::vector<•, MyAllocator<•> >
– where the bullet is a placeholder for a type-name.Consequently we do not propose the “typedef” syntax.On the other hand the sentencetemplate<class T> using Vec = std::vector<T, MyAllocator<T> >;
can be read/interpreted as: from now on, I’ll be using
Vec<T>
as a synonym forstd::vector<T, MyAllocator<T> >
. With that reading, the new syntax for aliasing seems reasonably logical.
To me, this implies continued support for the typedef
keyword in C++ because it can still make code more readable and understandable.
Updating the using
keyword was specifically for templates, and (as was pointed out in the accepted answer) when you are working with non-templates using
and typedef
are mechanically identical, so the choice is totally up to the programmer on the grounds of readability and communication of intent.
I know its Too late But I hope it will work new comers Try This Its Working ... :D

The advantage of passing an owner handle is that the FolderBrowserDialog will not be modal to that window. This prevents the user from interacting with your main application window while the dialog is active.
From my notes:
Which parses like this:
q=latN+lonW+(label) location of teardrop
t=k keyhole (satelite map)
t=h hybrid
ll=lat,-lon center of map
spn=w.w,h.h span of map, degrees
iwloc has something to do with the info window. hl is obviously language.

A parameter is something you have to fill in when you call a function. What you put in it is the argument.
Simply set: the argument goes into the parameter, an argument is the value of the parameter.

You can open a new popup window by following code:
var myWindow = window.open("", "newWindow", "width=500,height=700");
//window.open('url','name','specs');
Afterwards, you can add HTML using both myWindow.document.write();
or myWindow.document.body.innerHTML = "HTML";
What I will recommend is that first you create a new html file with any name. In this example I am using
newFile.html
And make sure to add all content in that file such as bootstrap cdn or jquery, means all the links and scripts. Then make a div with some id or use your body and give that a id
. in this example I have given id="mainBody"
to my newFile.html <body>
tag
<body id="mainBody">
Then open this file using
<script>
var myWindow = window.open("newFile.html", "newWindow", "width=500,height=700");
</script>
And add whatever you want to add in your body tag. using following code
<script>
var myWindow = window.open("newFile.html","newWindow","width=500,height=700");
myWindow.onload = function(){
let content = "<button class='btn btn-primary' onclick='window.print();'>Confirm</button>";
myWindow.document.getElementById('mainBody').innerHTML = content;
}
myWindow.window.close();
</script>
it is as simple as that.
Yes. See Named and Optional Arguments. Note that the default value needs to be a constant, so this is OK:
public string Foo(string myParam = "default value") // constant, OK
{
}
but this is not:
public void Bar(string myParam = Foo()) // not a constant, not OK
{
}
Sorry for tacking on to an old thread, but I think something that was said above may be incorrect/misleading.
From what I can tell .Timeout is NOT the connection time, it is the TOTAL time allowed for the entire life of the HttpWebRequest and response. Proof:
I Set:
.Timeout=5000
.ReadWriteTimeout=32000
The connect and post time for the HttpWebRequest took 26ms
but the subsequent call HttpWebRequest.GetResponse() timed out in 4974ms thus proving that the 5000ms was the time limit for the whole send request/get response set of calls.
I didn't verify if the DNS name resolution was measured as part of the time as this is irrelevant to me since none of this works the way I really need it to work--my intention was to time out quicker when connecting to systems that weren't accepting connections as shown by them failing during the connect phase of the request.
For example: I'm willing to wait 30 seconds on a connection request that has a chance of returning a result, but I only want to burn 10 seconds waiting to send a request to a host that is misbehaving.
too many ) parenthesis remove one of them.
I had a similar problem but the previous coder only provided the date in mm-yyyy format. My solution is simple but might prove helpful to some (I also wanted to be sure beginning and ending spaces were eliminated):
SELECT ... FROM ....WHERE
CONVERT(datetime,REPLACE(LEFT(LTRIM([MoYr]),2),'-
','')+'/01/'+RIGHT(RTRIM([MoYr]),4)) >= DATEADD(year,-1,GETDATE())
Give the same name in urls.py
path('detail/<int:id>', views.detail, name="detail"),
Just be aware also that catalina.out can be renamed - it can be set in /bin/catalina.sh with the CATALINA_OUT environment variable.
The way is to convert to binary and then to correct encoding
Below Code will work for this IFF it in the same order as its mentionened make sure you order is type then name, ng-model ng-init, value. thats It.
From the manual:
If the database server successfully prepares the statement, PDO::prepare() returns a PDOStatement object. If the database server cannot successfully prepare the statement, PDO::prepare() returns FALSE or emits PDOException (depending on error handling).
The prepare statement likely caused an error because the db would be unable to prepare the statement. Try testing for an error immediately after you prepare your query and before you execute it.
$qry = '
INSERT INTO non-existant-table (id, score)
SELECT id, 40
FROM another-non-existant-table
WHERE description LIKE "%:search_string%"
AND available = "yes"
ON DUPLICATE KEY UPDATE score = score + 40
';
$sth = $this->pdo->prepare($qry);
print_r($this->pdo->errorInfo());
The sscanf() solution is better in terms of code lines. My answer here is a user-build function that does almost the same as sscanf(). Stores the converted number in a pointer and returns a value called "val". If val comes out as zero, then the input is in unsupported format, hence conversion failed. Hence, use the pointer value only when val is non-zero.
It works only if the input is in base-10 form.
#include <stdio.h>
#include <string.h>
int CONVERT_3(double* Amt){
char number[100];
// Input the Data
printf("\nPlease enter the amount (integer only)...");
fgets(number,sizeof(number),stdin);
// Detection-Conversion begins

int val = 1;
int pos;
double Amount = 0;

Changing the info
to error
in simplelogging.properties
file will help in achieving your requirement.
Just change the value of the below line
org.slf4j.simpleLogger.defaultLogLevel=info
to
org.slf4j.simpleLogger.defaultLogLevel=error
Rather then write a lot of code, just do this:
{
dynamic tableNameAttribute = typeof(T).CustomAttributes.FirstOrDefault().ToString();
dynamic tableName = tableNameAttribute.Substring(tableNameAttribute.LastIndexOf('.'), tableNameAttribute.LastIndexOf('\\'));
}
should be done like that and not with delete operator:
localStorage.removeItem(key);
You can't use AJAX to fetch files from the user machine. This is absolutely the wrong way to go about it.
Use the FileReader API:
<input type="file" id="file input">
js:
console.log(document.getElementById("file input").files); // list of File objects
var file = document.getElementById("file input").files[0];
var reader = new FileReader();
content = reader.readAsText(file);
console.log(content);
Then parse content
as CSV. Keep in mind that your parser currently does not deal with escaped values in CSV like: value1,value2,"value 3","value ""4"""
Adding dependencies didn't fix the issue at my end.
The issue was happening at my end because of "additional" fields that are part of the "@Entity" class and don't exist in the database.
I removed the additional fields from the @Entity class and it worked.
Goodluck.
Some compilers support compound literals as an extention, allowing this construct:
Customer customerRecords[2];
customerRecords[0] = (Customer){25, "Bob Jones"};
customerRecords[1] = (Customer){26, "Jim Smith"};
But it's rather unportable.
The short answer for this is, "because that's what the C++ standard specifies".
Note that you can always specify a constructor that's different from the default, like so:
class Shape {
Shape() {...} //default constructor
Shape(int h, int w) {....} //some custom constructor
};
class Rectangle : public Shape {
Rectangle(int h, int w) : Shape(h, w) {...} //you can specify which base class constructor to call
}
The default constructor of the base class is called only if you don't specify which one to call.
The FontView library lets you use normal/unicode font characters as icons/graphics in your app. It can load the font via assets or a network location.
The benefit of this library is that:
1 - it takes care of remote resources for you
2 - scales the font size in dynamically sized views
3 - allows the font to easily be styled.
https://github.com/shellum/fontView
Example:
Layout:
<com.finalhack.fontview.FontView
android:id="@+id/someActionIcon"
android:layout_width="80dp"
android:layout_height="80dp" />
Java:
fontView.setupFont("fonts/font.ttf", character, FontView.ImageType.CIRCLE);
fontView.addForegroundColor(Color.RED);
fontView.addBackgroundColor(Color.WHITE);
Make a function which will not return null instead return an empty array you can go through below code to understand.
public static String[] getJavaFileNameList(File inputDir) {
String[] files = inputDir.list(new FilenameFilter() {
@Override
public boolean accept(File current, String name) {
return new File(current, name).isFile() && (name.endsWith("java"));
}
});
return files == null ? new String[0] : files;
}

l1 = [2,3,1,4,5]
l2 = [l1.index(x) for x in sorted(l1)]
Select select = new Select(driver.findElement(By.id("searchDropdownBox")));

String myArray[] = { "one", "two", "three" };
I am using python3 and found out that you need to encode your string before you can pass it into stdin:
p = Popen(['grep', 'f'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
out, err = p.communicate(input='one\ntwo\nthree\nfour\nfive\nsix\n'.encode())
print(out)
On 28 April 2019 official procedure is the following:
You're looking for a non-greedy (or lazy) match. To get a non-greedy match in regular expressions you need to use the modifier ?
after the quantifier. For example you can change .*
to .*?
.
By default grep
doesn't support non-greedy modifiers, but you can use grep -P
to use the Perl syntax.
Just to add my TSQL-scripted solution:
First of all; add a new database named backup_lookup
.
Then just run this script, inserting your own databases' root path and backup filepath
USE [master]
GO
RESTORE DATABASE backup_lookup
FROM DISK = 'C:\backup.bak'
WITH REPLACE,
MOVE 'Old Database Name' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\backup_lookup.mdf',
MOVE 'Old Database Name_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\backup_lookup_log.ldf'
GO
you can add produces = "text/plain;charset=UTF-8" to RequestMapping
@RequestMapping(value = "/rest/create/document", produces = "text/plain;charset=UTF-8")
@ResponseBody
public String create(Document document, HttpServletRespone respone) throws UnsupportedEncodingException {
Document newDocument = DocumentService.create(Document);
return jsonSerializer.serialize(newDocument);
}
The below command can set the icon on an executable file.
Remember the ".ico" file should present in the place of the path given in "Path_of_.ico_file".
pyinstaller.exe --onefile --windowed --icon="Path_of_.ico_file" app.py
For example:
If the app.py
file is present in the current directory and app.ico
is present inside the Images folder
within the current directory.
Then the command should be as below. The final executable file will be generated inside the dist folder
pyinstaller.exe --onefile --windowed --icon=Images\app.ico app.py
I'm not sure if I understood correctly, but is this what you mean?
out.write("this is line 1");
out.newLine();
out.write("this is line 2");
out.newLine();

Assuming that you have multiple containers and you want to aggregate the logs into a single file, you need to use some log aggregator like fluentd. fluentd is supported as logging driver for docker containers.
So in docker-compose, you need to define the logging driver
service1:
image: webapp:0.0.1
logging:
driver: "fluentd"
options:
tag: service1
service2:
image: myapp:0.0.1
logging:
driver: "fluentd"
options:
tag: service2
The second step would be update the fluentd conf to cater the logs for both service 1 and service 2
<match service1>
@type copy
<store>
@type file
path /fluentd/log/service/service.*.log
time_slice_format %Y%m%d
time_slice_wait 10m
time_format %Y%m%dT%H%M%S%z
</store>
</match>
<match service2>
@type copy
<store>
@type file
path /fluentd/log/service/service.*.log
time_slice_format %Y%m%d
time_slice_wait 10m
time_format %Y%m%dT%H%M%S%
</store>
</match>
In this config, we are asking logs to be written to a single file to this path
/fluentd/log/service/service.*.log
and the third step would be to run the customized fluentd which will start writing the logs to file.
Here is the link for step by step instructions
Bit Long, but correct way since you get more control over log files path etc and it works well in Docker Swarm too .
All process for remote login. Remote login is off by default.You need to open it manually for all ip..to give access all ip
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password';
Specific Ip
GRANT ALL PRIVILEGES ON *.* TO 'root'@'your_desire_ip' IDENTIFIED BY 'password';
then
flush privileges;
You can check your User Host & Password
SELECT host,user,authentication_string FROM mysql.user;
Now your duty is to change this
bind-address = 127.0.0.1
You can find this on
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
if you not find this on there then try this
sudo nano /etc/mysql/my.cnf
comment in this
#bind-address = 127.0.0.1
Then restart Mysql
sudo service mysql restart
Now enjoy remote login
I realize this is a little old, but, yes it can be done. Some javascript to get you started:
viewport = document.querySelector("meta[name=viewport]");
viewport.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0');
Just change the parts you need and Mobile Safari will respect the new settings.
Update:
If you don't already have the meta viewport tag in the source, you can append it directly with something like this:
var metaTag=document.createElement('meta');
metaTag.name = "viewport"
metaTag.content = "width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"
document.getElementsByTagName('head')[0].appendChild(metaTag);
Or if you're using jQuery:
$('head').append('<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">');
Find out two pieces of information
$> telnet <hostname or ip> <port>
Assuming the daemon is up and running and listening on that port it should etablish a telnet session. Likely causes:
Encountered this in Ubuntu for Windows, try running first
sudo apt-get update
sudo apt-get upgrade
then
sudo apt-get install npm

cannot be represented as a 32-bit integer (type int
). It can be represented as a 64-bit integer (type long
). long literals in Java end with an "L": 600851475143L
You have to use start and $NUL for this in Windows PowerShell:
Type in this command assuming mySum
is the name of your application and 5
10
are command line arguments you are sending.
start .\mySum 5 10 > $NUL 2>&1
The start
command will start a detached process, a similar effect to &
. The /B
option prevents start from opening a new terminal window if the program you are running is a console application. and NUL
is Windows' equivalent of /dev/null
. The 2>&1
at the end will redirect stderr to stdout, which will all go to NUL
.
set view engine following way
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
For what it's worth, here's a solution I came up with using the dom4j library. (I did check that it works.)
Read the XML fragment into a org.dom4j.Document
(note: all the XML classes used below are from org.dom4j; see Appendix):
String newNode = "<node>value</node>"; // Convert this to XML
SAXReader reader = new SAXReader();
Document newNodeDocument = reader.read(new StringReader(newNode));
Then get the Document into which the new node is inserted, and the parent Element (to be) from it. (Your org.w3c.dom.Document would need to be converted to org.dom4j.Document here.) For testing purposes, I created one like this:
Document originalDoc =
new SAXReader().read(new StringReader("<root><given></given></root>"));
Element givenNode = originalDoc.getRootElement().element("given");
Adding the new child element is very simple:
givenNode.add(newNodeDocument.getRootElement());
Done. Outputting originalDoc
now yields:
<?xml version="1.0" encoding="utf-8"?>
<root>
<given>
<node>value</node>
</given>
</root>
Appendix: Because your question talks about org.w3c.dom.Document
, here's how to convert between that and org.dom4j.Document
.
// dom4j -> w3c
DOMWriter writer = new DOMWriter();
org.w3c.dom.Document w3cDoc = writer.write(dom4jDoc);
// w3c -> dom4j
DOMReader reader = new DOMReader();
Document dom4jDoc = reader.read(w3cDoc);
(If you'd need both kind of Document
s regularly, it might make sense to put these in neat utility methods, maybe in a class called XMLUtils
or something like that.)
Maybe there are better ways to do this, even without any 3rd party libraries. But out of the solutions presented so far, in my view this is the easiest way, even if you need to do the dom4j <-> w3c conversions.
Update (2011): before adding dom4j dependency to your code, note that it is not an actively maintained project, and has some other problems too. Improved version 2.0 has been in the works for ages, but there's only an alpha version available. You may want to consider an alternative, like XOM, instead; read more in the question linked above.
