Maybe I'm not understanding the question but here is my simple solution that works -
# I want to Display total heads bent this machine so I define a label -
TotalHeadsLabel3 = Label(leftFrame)
TotalHeadsLabel3.config(font=Helv12,fg='blue',text="Total heads " + str(TotalHeads))
TotalHeadsLabel3.pack(side=TOP)
# I update the int variable adding the quantity bent -
TotalHeads = TotalHeads + headQtyBent # update ready to write to file & display
TotalHeadsLabel3.config(text="Total Heads "+str(TotalHeads)) # update label with new qty
I agree that labels are not automatically updated but can easily be updated with the
<label name>.config(text="<new text>" + str(<variable name>))
That just needs to be included in your code after the variable is updated.
JLabel label = new JLabel ("Text Color: Red");
label.setForeground (Color.red);
this should work
You need to create a new Font
mainForm.lblName.Font = new Font("Arial", mainForm.lblName.Font.Size);
If you want to use this in VBA:
For i = 1 To X
UserForm1.Controls("Label" & i).Caption = MySheet.Cells(i + 1, i).Value
Next
just enter the following command on command prompt after launching the app:
adb shell dumpsys window windows | find "mCurrentFocus"
if executing the command on linux terminal replace find by grep
I have tried directlabels
package for putting text labels. In the case of scatter plots it's not still perfect, but much better than manually adjusting the positions, specially in the cases that you are preparing the draft plots and not the final one - so you need to change and make plot again and again -.
Either structure is valid and accessible, but the for
attribute should be equal to the id
of the input element:
<input type="radio" ... id="r1" /><label for="r1">button text</label>
or
<label for="r1"><input type="radio" ... id="r1" />button text</label>
The for
attribute is optional in the second version (label containing input), but IIRC there were some older browsers that didn't make the label text clickable unless you included it. The first version (label after input) is easier to style with CSS using the adjacent sibling selector +
:
input[type="radio"]:checked+label {font-weight:bold;}
To make the text on the tick labels fully visible and read in the same direction as the y-axis label, change the last line to
q + theme(axis.text.x=element_text(angle=90, hjust=1))
Try something like this in your aspx page
<asp:Label ID="myLabel" runat="server"></asp:Label>
and then in your codebehind you can just do
myLabel.Text = "My Label";
I believe you want bgcolor. Something like this:
document.getElementById("button").bgcolor="#ffffff";
Here are a couple of demos that might help:
You can make a text align to the right inside of any element, including labels.
Html:
<label>Text</label>
Css:
label {display:block; width:x; height:y; text-align:right;}
This way, you give a width and height to your label and make any text inside of it align to the right.
To get height for the NSAttributedString use this function below. Where width - the width of your UILabel or UITextView
func getHeight(for attributedString: NSAttributedString, font: UIFont, width: CGFloat) -> CGFloat {
let textStorage = NSTextStorage(attributedString: attributedString)
let textContainter = NSTextContainer(size: CGSize(width: width, height: CGFloat.greatestFiniteMagnitude))
let layoutManager = NSLayoutManager()
layoutManager.addTextContainer(textContainter)
textStorage.addLayoutManager(layoutManager)
textStorage.addAttribute(NSAttributedString.Key.font, value: font, range: NSMakeRange(0, textStorage.length))
textContainter.lineFragmentPadding = 0.0
layoutManager.glyphRange(for: textContainter)
return layoutManager.usedRect(for: textContainter).size.height
}
To get height for String use this function, It is almost identical like the previous method:
func getHeight(for string: String, font: UIFont, width: CGFloat) -> CGFloat {
let textStorage = NSTextStorage(string: string)
let textContainter = NSTextContainer(size: CGSize(width: width, height: CGFloat.greatestFiniteMagnitude))
let layoutManager = NSLayoutManager()
layoutManager.addTextContainer(textContainter)
textStorage.addLayoutManager(layoutManager)
textStorage.addAttribute(NSAttributedString.Key.font, value: font, range: NSMakeRange(0, textStorage.length))
textContainter.lineFragmentPadding = 0.0
layoutManager.glyphRange(for: textContainter)
return layoutManager.usedRect(for: textContainter).size.height
}
jQuery has a function that can do this:
include the following script in your head:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"></script>
(or just download the jQuery.js file online and include it locally)
use this script to toggle the check box when the input is clicked:
var toggle = false;
$("#INPUTNAMEHERE").click(function() {
$("input[type=checkbox]").attr("checked",!toggle);
toggle = !toggle;
});
That should do what you want if I understood what you were trying to do.
Use par(las=1)
.
See ?par
:
las
numeric in {0,1,2,3}; the style of axis labels.
0: always parallel to the axis [default],
1: always horizontal,
2: always perpendicular to the axis,
3: always vertical.
very simple
$('#label-ID').text("label value which you want to set");
Do display: inline-block
:
#report-upload-form label {
padding-left:26px;
width:125px;
text-transform: uppercase;
display:inline-block
}
I was having the same problem because i was using
$("#LabelID").val("some value");
I learned that you can either use the provisional jquery method to clear it first then append:
$("#LabelID").empty();
$("#LabelID").append("some Text");
Or conventionaly, you could use:
$("#LabelID").text("some value");
OR
$("#LabelID").html("some value");
use this
style:
<style type="text/css">
.defaultLabel_on { color:#0F0; }
.defaultLabel_off { color:#CCC; }
</style>
html:
javascript:
function defaultLabelClean() {
inputs = document.getElementsByTagName("input");
for (var i = 0; i < inputs.length; i++) {
if (inputs[i].value == inputs[i].getAttribute("innerLabel")) {
inputs[i].value = '';
}
}
}
function defaultLabelAttachEvents(element, label) {
element.setAttribute("innerLabel", label);
element.onfocus = function(e) {
if (this.value==label) {
this.className = 'defaultLabel_on';
this.value = '';
}
}
element.onblur = function(e) {
if (this.value=='') {
this.className = 'defaultLabel_off';
this.value = element.getAttribute("innerLabel");
}
}
if (element.value=='') {
element.className = 'defaultLabel_off';
element.value = element.getAttribute("innerLabel");
}
}
defaultLabelAttachEvents(document.getElementById('MYID'), "MYLABEL");
Just remember to call defaultLabelClean() function before submit form.
good work
I would recommend setting AutoEllipsis
property of label to true
and AutoSize
to false
. If text length exceeds label bounds, it'll add three dots (...)
at the end and automatically set the complete text as a tooltip. So users can see the complete text by hovering over the label.
You can create a big subplot that covers the two subplots and then set the common labels.
import random
import matplotlib.pyplot as plt
x = range(1, 101)
y1 = [random.randint(1, 100) for _ in range(len(x))]
y2 = [random.randint(1, 100) for _ in range(len(x))]
fig = plt.figure()
ax = fig.add_subplot(111) # The big subplot
ax1 = fig.add_subplot(211)
ax2 = fig.add_subplot(212)
# Turn off axis lines and ticks of the big subplot
ax.spines['top'].set_color('none')
ax.spines['bottom'].set_color('none')
ax.spines['left'].set_color('none')
ax.spines['right'].set_color('none')
ax.tick_params(labelcolor='w', top=False, bottom=False, left=False, right=False)
ax1.loglog(x, y1)
ax2.loglog(x, y2)
# Set common labels
ax.set_xlabel('common xlabel')
ax.set_ylabel('common ylabel')
ax1.set_title('ax1 title')
ax2.set_title('ax2 title')
plt.savefig('common_labels.png', dpi=300)
Another way is using fig.text() to set the locations of the common labels directly.
import random
import matplotlib.pyplot as plt
x = range(1, 101)
y1 = [random.randint(1, 100) for _ in range(len(x))]
y2 = [random.randint(1, 100) for _ in range(len(x))]
fig = plt.figure()
ax1 = fig.add_subplot(211)
ax2 = fig.add_subplot(212)
ax1.loglog(x, y1)
ax2.loglog(x, y2)
# Set common labels
fig.text(0.5, 0.04, 'common xlabel', ha='center', va='center')
fig.text(0.06, 0.5, 'common ylabel', ha='center', va='center', rotation='vertical')
ax1.set_title('ax1 title')
ax2.set_title('ax2 title')
plt.savefig('common_labels_text.png', dpi=300)
var label = $('#current_month');
var month = label.val('month');
var year = label.val('year');
var text = label.text();
alert(text);
<label year="2010" month="6" id="current_month"> June 2010</label>
Old question, but I had this issue as well, so after assigning the Text property, calling Refresh()
will update the text.
Label1.Text = "Du har nu lånat filmen:" + test;
Refresh();
put them both inside a div
with nowrap.
<div style="white-space:nowrap">
<label for="id1">label1:</label>
<input type="text" id="id1"/>
</div>
Wrap the checkbox within a label
tag:
<label><input type="checkbox" name="checkbox" value="value">Text</label>
for
AttributeUse the for
attribute (match the checkbox id
):
<input type="checkbox" name="checkbox" id="checkbox_id" value="value">
<label for="checkbox_id">Text</label>
NOTE: ID must be unique on the page!
Since the other answers don't mention it, a label can include up to 1 input and omit the for
attribute, and it will be assumed that it is for the input within it.
Excerpt from w3.org (with my emphasis):
[The for attribute] explicitly associates the label being defined with another control. When present, the value of this attribute must be the same as the value of the id attribute of some other control in the same document. When absent, the label being defined is associated with the element's contents.
To associate a label with another control implicitly, the control element must be within the contents of the LABEL element. In this case, the LABEL may only contain one control element. The label itself may be positioned before or after the associated control.
Using this method has some advantages over for
:
No need to assign an id
to every checkbox (great!).
No need to use the extra attribute in the <label>
.
The input's clickable area is also the label's clickable area, so there aren't two separate places to click that can control the checkbox - only one, no matter how far apart the <input>
and actual label text are, and no matter what kind of CSS you apply to it.
Demo with some CSS:
label {
border:1px solid #ccc;
padding:10px;
margin:0 0 10px;
display:block;
}
label:hover {
background:#eee;
cursor:pointer;
}
_x000D_
<label><input type="checkbox" />Option 1</label>
<label><input type="checkbox" />Option 2</label>
<label><input type="checkbox" />Option 3</label>
_x000D_
Just to share my idea...
I created a custom class to inherit the Label class. I added a private variable assigned as a Tooltip class and a public property, TooltipText. Then, gave it a MouseEnter delegate method. This is an easy way to work with multiple Label controls and not have to worry about assigning your Tooltip control for each Label control.
public partial class ucLabel : Label
{
private ToolTip _tt = new ToolTip();
public string TooltipText { get; set; }
public ucLabel() : base() {
_tt.AutoPopDelay = 1500;
_tt.InitialDelay = 400;
// _tt.IsBalloon = true;
_tt.UseAnimation = true;
_tt.UseFading = true;
_tt.Active = true;
this.MouseEnter += new EventHandler(this.ucLabel_MouseEnter);
}
private void ucLabel_MouseEnter(object sender, EventArgs ea)
{
if (!string.IsNullOrEmpty(this.TooltipText))
{
_tt.SetToolTip(this, this.TooltipText);
_tt.Show(this.TooltipText, this.Parent);
}
}
}
In the form or user control's InitializeComponent method (the Designer code), reassign your Label control to the custom class:
this.lblMyLabel = new ucLabel();
Also, change the private variable reference in the Designer code:
private ucLabel lblMyLabel;
I used this to retrieve data from MySql Database:
AccessText a = new AccessText();
a.Text=reader[1].ToString(); // MySql reader
a.Width = 70;
a.TextWrapping = TextWrapping.WrapWithOverflow;
labels[i].Content = a;
I know this is old, but I had trouble with some solutions and pieced this together. I have tested this on Windows (Chrome, Firefox and MSIE) and OS X (Chrome and Safari) and believe this is the simplest solution. It works with these three style of attaching a label.
<label><input type="checkbox" class="c123" id="cb1" name="item1">item1</label>
<input type="checkbox" class="c123" id="cb2" name="item2">item2</input>
<input type="checkbox" class="c123" id="cb3" name="item3"><label for="cb3">item3</label>
Using jQuery:
$(".c123").click(function() {
$cb = $(this);
$lb = $(this).parent();
alert( $cb.attr('id') + ' = ' + $lb.text() );
});
My JSFiddle: http://jsfiddle.net/pnosko/6PQCw/
If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40)
.
If you use pyplot
programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40)
or afterwards with ax.yaxis.label.set_size(40)
.
The <label>
tag allows you to click on the label, and it will be treated like clicking on the associated input element. There are two ways to create this association:
One way is to wrap the label element around the input element:
<label>Input here:
<input type='text' name='theinput' id='theinput'>
</label>
The other way is to use the for
attribute, giving it the ID of the associated input:
<label for="theinput">Input here:</label>
<input type='text' name='whatever' id='theinput'>
This is especially useful for use with checkboxes and buttons, since it means you can check the box by clicking on the associated text instead of having to hit the box itself.
Read more about this element in MDN.
You need text()
or html()
for label not val()
The function should not be called for label instead it is used to get values of input like text or checkbox etc.
Change
value = $("#telefon").val();
To
value = $("#telefon").text();
There are several problems in your code.
First the big ones:
You are creating a new figure and a new axes in every iteration of your loop ?
put fig = plt.figure
and ax = fig.add_subplot(1,1,1)
outside of the loop.
Don't use the Locators. Call the functions ax.set_xticks()
and ax.grid()
with the correct keywords.
With plt.axes()
you are creating a new axes again. Use ax.set_aspect('equal')
.
The minor things:
You should not mix the MATLAB-like syntax like plt.axis()
with the objective syntax.
Use ax.set_xlim(a,b)
and ax.set_ylim(a,b)
This should be a working minimal example:
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(1, 1, 1)
# Major ticks every 20, minor ticks every 5
major_ticks = np.arange(0, 101, 20)
minor_ticks = np.arange(0, 101, 5)
ax.set_xticks(major_ticks)
ax.set_xticks(minor_ticks, minor=True)
ax.set_yticks(major_ticks)
ax.set_yticks(minor_ticks, minor=True)
# And a corresponding grid
ax.grid(which='both')
# Or if you want different settings for the grids:
ax.grid(which='minor', alpha=0.2)
ax.grid(which='major', alpha=0.5)
plt.show()
Output is this:
This one Works for me with asp label control.
function changeEmaillbl() {
if (document.getElementById('<%=rbAgency.ClientID%>').checked = true) {
document.getElementById('<%=lblUsername.ClientID%>').innerHTML = 'Accredited No.:';
}
}
You can either give class name to all label so that all can have same width :
.class-name { width:200px;}
Example
.labelname{ width:200px;}
or you can simple give rest of label
label { width:200px; display: inline-block;}
In Bootstrap 3 they do not have separate classes for different styles of labels.
http://getbootstrap.com/components/
However, you can customize bootstrap classes that way. In your css file
.lb-sm {
font-size: 12px;
}
.lb-md {
font-size: 16px;
}
.lb-lg {
font-size: 20px;
}
Alternatively, you can use header tags to change the sizes. For example, here is a medium sized label and a small-sized label
<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<h3>Example heading <span class="label label-default">New</span></h3>_x000D_
<h6>Example heading <span class="label label-default">New</span></h6>
_x000D_
They might add size classes for labels in future Bootstrap versions.
[Note: edited to modernize ggplot syntax]
Your example is not reproducible since there is no ex1221new
(there is an ex1221
in Sleuth2
, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot
. One advantage is that ggplot
works with data.frame
s directly.
You can set the labels with xlab()
and ylab()
, or make it part of the scale_*.*
call.
library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area() +
xlab("My x label") +
ylab("My y label") +
ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area("Nitrogen") +
scale_x_continuous("My x label") +
scale_y_continuous("My y label") +
ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs
function
ggplot(ex1221, aes(Discharge, Area)) +
geom_point(aes(size=NO3)) +
scale_size_area() +
labs(size= "Nitrogen",
x = "My x label",
y = "My y label",
title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")
which gives an identical figure to the one above.
Try passing width=200
as additional paramater when creating the Label.
This should work in creating label with specified width.
If you want to change it later, you can use:
label.config(width=200)
As you want to change the size of font itself you can try:
label.config(font=("Courier", 44))
It's fairly easy to do. Create a UILabel
sublcass with a verticalAlignment
property and override textRectForBounds:limitedToNumberOfLines
to return the correct bounds for a top, middle or bottom vertical alignment. Here's the code:
SOLabel.h
#import <UIKit/UIKit.h>
typedef enum
{
VerticalAlignmentTop = 0, // default
VerticalAlignmentMiddle,
VerticalAlignmentBottom,
} VerticalAlignment;
@interface SOLabel : UILabel
@property (nonatomic, readwrite) VerticalAlignment verticalAlignment;
@end
SOLabel.m
@implementation SOLabel
-(id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (!self) return nil;
// set inital value via IVAR so the setter isn't called
_verticalAlignment = VerticalAlignmentTop;
return self;
}
-(VerticalAlignment) verticalAlignment
{
return _verticalAlignment;
}
-(void) setVerticalAlignment:(VerticalAlignment)value
{
_verticalAlignment = value;
[self setNeedsDisplay];
}
// align text block according to vertical alignment settings
-(CGRect)textRectForBounds:(CGRect)bounds
limitedToNumberOfLines:(NSInteger)numberOfLines
{
CGRect rect = [super textRectForBounds:bounds
limitedToNumberOfLines:numberOfLines];
CGRect result;
switch (_verticalAlignment)
{
case VerticalAlignmentTop:
result = CGRectMake(bounds.origin.x, bounds.origin.y,
rect.size.width, rect.size.height);
break;
case VerticalAlignmentMiddle:
result = CGRectMake(bounds.origin.x,
bounds.origin.y + (bounds.size.height - rect.size.height) / 2,
rect.size.width, rect.size.height);
break;
case VerticalAlignmentBottom:
result = CGRectMake(bounds.origin.x,
bounds.origin.y + (bounds.size.height - rect.size.height),
rect.size.width, rect.size.height);
break;
default:
result = bounds;
break;
}
return result;
}
-(void)drawTextInRect:(CGRect)rect
{
CGRect r = [self textRectForBounds:rect
limitedToNumberOfLines:self.numberOfLines];
[super drawTextInRect:r];
}
@end
The tutorial @Henrik mentioned is an excellent resource for learning how to create plots with the ggplot2
package.
An example with your data:
# transforming the data from wide to long
library(reshape2)
dfm <- melt(df, id = "TY")
# creating a scatterplot
ggplot(data = dfm, aes(x = TY, y = value, color = variable)) +
geom_point(size=5) +
labs(title = "Temperatures\n", x = "TY [°C]", y = "Txxx", color = "Legend Title\n") +
scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
theme_bw() +
theme(axis.text.x = element_text(size = 14), axis.title.x = element_text(size = 16),
axis.text.y = element_text(size = 14), axis.title.y = element_text(size = 16),
plot.title = element_text(size = 20, face = "bold", color = "darkgreen"))
this results in:
As mentioned by @user2739472 in the comments: If you only want to change the legend text labels and not the colours from ggplot's default palette, you can use scale_color_hue(labels = c("T999", "T888"))
instead of scale_color_manual()
.
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.colors import ListedColormap
#discrete color scheme
cMap = ListedColormap(['white', 'green', 'blue','red'])
#data
np.random.seed(42)
data = np.random.rand(4, 4)
fig, ax = plt.subplots()
heatmap = ax.pcolor(data, cmap=cMap)
#legend
cbar = plt.colorbar(heatmap)
cbar.ax.get_yaxis().set_ticks([])
for j, lab in enumerate(['$0$','$1$','$2$','$>3$']):
cbar.ax.text(.5, (2 * j + 1) / 8.0, lab, ha='center', va='center')
cbar.ax.get_yaxis().labelpad = 15
cbar.ax.set_ylabel('# of contacts', rotation=270)
# put the major ticks at the middle of each cell
ax.set_xticks(np.arange(data.shape[1]) + 0.5, minor=False)
ax.set_yticks(np.arange(data.shape[0]) + 0.5, minor=False)
ax.invert_yaxis()
#labels
column_labels = list('ABCD')
row_labels = list('WXYZ')
ax.set_xticklabels(column_labels, minor=False)
ax.set_yticklabels(row_labels, minor=False)
plt.show()
You were very close. Once you have a reference to the color bar axis, you can do what ever you want to it, including putting text labels in the middle. You might want to play with the formatting to make it more visible.
You can set display attribute as none to hide a label.
<label id="excel-data-div" style="display: none;"></label>
Have you tried .innerText
or .value
instead of .innerHTML
?
You probably have to add a class/id to and then make another CSS declaration that hides it as well.
The for
attribute is called htmlFor
for consistency with the DOM property API. If you're using the development build of React, you should have seen a warning in your console about this.
jquery function is most important
<script>
$(function(){
var stickyHeaderTop = $('#stickytypeheader').offset().top;
$(window).scroll(function(){
if( $(window).scrollTop() > stickyHeaderTop ) {
$('#stickytypeheader').css({position: 'fixed', top: '0px'});
$('#sticky').css('display', 'block');
} else {
$('#stickytypeheader').css({position: 'static', top: '0px'});
$('#sticky').css('display', 'none');
}
});
});
</script>
Then use JQuery Lib...
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
Now use HTML
<div id="header">
<p>This text is non sticky</p>
<p>This text is non sticky</p>
<p>This text is non sticky</p>
<p>This text is non sticky</p>

You could use only delegate which is best for callback functions:
public class ServerRequest
{
public delegate void CallBackFunction(string input);
public void DoRequest(string request, CallBackFunction callback)
{
// do stuff....
callback(request);
}
}
and consume this like below:
public class Class1
{
private void btn_click(object sender, EventArgs e)
{
ServerRequest sr = new ServerRequest();
var callback = new ServerRequest.CallBackFunction(CallbackFunc);
sr.DoRequest("myrequest",callback);
}
void CallbackFunc(string something)
{
}
}
In a general way, if you want to pick up the first N rows from the J column from pandas dataframe
the best way to do this is:
data = dataframe[0:N][:,J]
This should be working. Please have a look at this fiddle.
$(function() {
$( "#slider" ).slider();
});//Links to jsfiddle must be accompanied by code
Make sure you're loading the libraries in this order: jQuery, jQuery UI CSS, jQuery UI, AngularJS.
I prefer to use "await" command and async functions to get rid of confusions of promises,
In this case I would write an asynchronous function first, this will be used instead of the anonymous function called under "promise.then" part of this question :
async function SubFunction(output){
// Call to database , returns a promise, like an Ajax call etc :
const response = await axios.get( GetApiHost() + '/api/some_endpoint')
// Return :
return response;
}
and then I would call this function from main function :
async function justTesting() {
const lv_result = await SubFunction(output);
return lv_result + 1;
}
Noting that I returned both main function and sub function to async functions here.
My guess is they did this to make life easier for people writing tools that process Java code, and to some lesser degree also people who are reading Java code.
If you allow the super()
or this()
call to move around, there are more variations to check for. For example if you move the super()
or this()
call into a conditional if()
it might have to be smart enough to insert an implicit super()
into the else
. It might need to know how to report an error if you call super()
twice, or use super()
and this()
together. It might need to disallow method calls on the receiver until super()
or this()
is called and figuring out when that is becomes complicated.
Making everyone do this extra work probably seemed like a greater cost than benefit.
This post already has a checked answer, but the answer doesn't filter for null values. The correct answer should prevent null values by using the Object::nonNull function as a predicate.
BigDecimal result = invoiceList.stream()
.map(Invoice::total)
.filter(Objects::nonNull)
.filter(i -> (i.getUnit_price() != null) && (i.getQuantity != null))
.reduce(BigDecimal.ZERO, BigDecimal::add);
This prevents null values from attempting to be summed as we reduce.
you can use
style="display:none"
Ex:
<asp:TextBox ID="txbProv" runat="server" style="display:none"></asp:TextBox>
You can use the following command line to start the service:
net start *servicename*
you can do some thing like this:
a {
color: #0060B6;
text-decoration: none;
}
a:hover
{
color:#00A0C6;
text-decoration:none;
cursor:pointer;
}
if text-decoration doesn't work then include text-decoration: none !important;
As with other answers, adding the "extras" subscribed channels to a CentOS 7 Spacewalk deployment solves this problem as well.
In my case, I was mistaken the function parameters, which are:
context.drawImage(image, left, top);
context.drawImage(image, left, top, width, height);
If you expect them to be
context.drawImage(image, width, height);
you will place the image just outside the canvas with the same effects as described in the question.
if only the key column is the same in both tables then try using the following way (Approach 1):
left. join(right , 'key', 'inner')
rather than below(approach 2):
left. join(right , left.key == right.key, 'inner')
Pros of using approach 1:
Cons of using approach 1:
On ubuntu
sudo apt-get install librxtx-java then
add RXTX jars to the project which are in
usr/share/java
I also tried to make an executable jar file that I could run with the following command:
java -jar <jarfile>
After some searching I found the following link:
Packaging and Deploying Desktop Java Applications
I set the project's main class:
Then in the fodler dist the newly created jar should be executable with the command I mentioned above.
Another version of Miroslav Zadravec's code, but slightly more automated and universal:
public Form1()
{
InitializeComponent();
dataGridView1.DataSource = source;
for (int i = 0; i < dataGridView1.Columns.Count - 1; i++) {
dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
}
dataGridView1.Columns[dataGridView1.Columns.Count].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
}
void Form1Shown(object sender, EventArgs e)
{
for ( int i = 0; i < dataGridView1.Columns.Count; i++ )
{
int colw = dataGridView1.Columns[i].Width;
dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
dataGridView1.Columns[i].Width = colw;
}
}
I put second part into separate event, because I fill datagridvew
in initialization of form and if both parts are there, nothing is changing, because probably autosize calculates widths after datagridview
is displayed, so the widths are still default in Form1()
method. After finishing this method, autosize does its trick and immediately after that (when form is shown) we can set the widths by second part of the code (here in Form1Shown
event). This is working for me like a charm.
This is my code:
IQueryable<AuctionRecord> records = db.AuctionRecord;
var count = records.Count();
Make sure the variable is defined as IQueryable then when you use Count() method, EF will execute something like
select count(*) from ...
Otherwise, if the records is defined as IEnumerable, the sql generated will query the entire table and count rows returned.
1. Performance:
Assume your where clause is like this:
WHERE NAME='JON'
If the NAME column is of any type other than nvarchar or nchar, then you should not specify the N prefix. However, if the NAME column is of type nvarchar or nchar, then if you do not specify the N prefix, then 'JON' is treated as non-unicode. This means the data type of NAME column and string 'JON' are different and so SQL Server implicitly converts one operand’s type to the other. If the SQL Server converts the literal’s type to the column’s type then there is no issue, but if it does the other way then performance will get hurt because the column's index (if available) wont be used.
2. Character set:
If the column is of type nvarchar or nchar, then always use the prefix N while specifying the character string in the WHERE criteria/UPDATE/INSERT clause. If you do not do this and one of the characters in your string is unicode (like international characters - example - a) then it will fail or suffer data corruption.
This rule
main: producer.o consumer.o AddRemove.o
$(COMPILER) -pthread $(CCFLAGS) -o producer.o consumer.o AddRemove.o
is wrong. It says to create a file named producer.o (with -o producer.o
), but you want to create a file named main
. Please excuse the shouting, but ALWAYS USE $@ TO REFERENCE THE TARGET:
main: producer.o consumer.o AddRemove.o
$(COMPILER) -pthread $(CCFLAGS) -o $@ producer.o consumer.o AddRemove.o
As Shahbaz rightly points out, the gmake professionals would also use $^
which expands to all the prerequisites in the rule. In general, if you find yourself repeating a string or name, you're doing it wrong and should use a variable, whether one of the built-ins or one you create.
main: producer.o consumer.o AddRemove.o
$(COMPILER) -pthread $(CCFLAGS) -o $@ $^
Java passes everything by value!!

// variable1 now points to variable3

Try this:
printf '\n%s\n' 'I want this on a new line!'
That allows you to separate the formatting from the actual text. You can use multiple placeholders and multiple arguments.
quantity=38; price=142.15; description='advanced widget'
$ printf '%8d%10.2f %s\n' "$quantity" "$price" "$description"
38 142.15 advanced widget
Use Context.getDatabasePath(databasename). The context can be obtained from your application.
If you get previous data back it can be either a) the data was stored in an unconventional location and therefore not deleted with uninstall or b) Titanium backed up the data with the app (it can do that).
Properties prop = new Properties();
prop.load(...); // FileInputStream
prop.setProperty("key", "value");
prop.store(...); // FileOutputStream
Here I propose a way to do this exclusively using the Bootstrap framework built-in functionality.
div
has an ID.class
"collapse", this will hide your block by
default. If you want your div to be collapsible AND be shown by
default you need to add "in" class to the collapse. Otherwise the
toggle behavior will not work properly.data-toggle="collapse"
to instruct
Bootstrap to add an appropriate toggle script to this tag.Here is a code sample than can be copy-pasted directly on a page that already includes Bootstrap framework (up to version 3.4.1):
<a href="#Foo" class="btn btn-default" data-toggle="collapse">Toggle Foo</a>
<button href="#Bar" class="btn btn-default" data-toggle="collapse">Toggle Bar</button>
<div id="Foo" class="collapse">
This div (Foo) is hidden by default
</div>
<div id="Bar" class="collapse in">
This div (Bar) is shown by default and can toggle
</div>
Take the case of two tables, Books
and Orders
. In case, we increase the number of books in a particular order with Order.ID = 1002
in Orders
table then we also need to reduce that the total number of books available in our stock by the same number in Books
table.
UPDATE Books, Orders
SET Orders.Quantity = Orders.Quantity + 2,
Books.InStock = Books.InStock - 2
WHERE
Books.BookID = Orders.BookID
AND Orders.OrderID = 1002;
In Python 2:
mylist = ['x', 3, 'b']
print '[%s]' % ', '.join(map(str, mylist))
In Python 3 (where print
is a builtin function and not a syntax feature anymore):
mylist = ['x', 3, 'b']
print('[%s]' % ', '.join(map(str, mylist)))
Both return:
[x, 3, b]
This is using the map()
function to call str for each element of mylist, creating a new list of strings that is then joined into one string with str.join()
. Then, the %
string formatting operator substitutes the string in instead of %s
in "[%s]"
.
You need to cast it to a string (not an array of string) since it's a single value.
var cellValue = (string)(excelWorksheet.Cells[10, 2] as Excel.Range).Value;
$data = '+11234567890';
if( preg_match( '/^\+\d(\d{3})(\d{3})(\d{4})$/', $data, $matches ) )
{
$result = $matches[1] . '-' .$matches[2] . '-' . $matches[3];
return $result;
}
The first /var/run/docker.sock refers to the same path in your boot2docker virtual machine. Correcly write for windows /var/run/docker.sock
To remove all array elements irrespective of any given id, use this:
collection.update(
{ },
{ $pull: { 'contact.phone': { number: '+1786543589455' } } }
);

Swing + SwingX + Miglayout is my combination of choice. Miglayout is so much simpler than Swings perceived 200 different layout managers and much more powerful. Also, it provides you with the ability to "debug" your layouts, which is especially handy when creating complex layouts.
We can use ls
and many other Linux commands in Windows cmd. Just follow these steps.
Steps:
1) Install Git in your computer - https://git-scm.com/downloads.
2) After installing Git, go to the folder in which Git is installed.
Mostly it will be in C drive
and then Program Files
Folder.
3) In Program Files
folder, you will find the folder named Git
, find the bin
folder
which is inside usr
folder in the Git folder.
In my case, the location for bin folder was - C:\Program Files\Git\usr\bin
4) Add this location (C:\Program Files\Git\usr\bin
) in path variable, in system
environment variables.
5) You are done. Restart cmd and try to run ls
and other Linux commands.
You need to actually run a webserver, and make the get request to a URI on that server, rather than making the get request to a file; e.g. change the line:
$.get("C:/xampp/htdocs/webname/resources/templates/signup.php",
to read something like:
$.get("http://localhost/resources/templates/signup.php",
and the initial request page needs to be made over http as well.
It seems the problem is you send the form request to welcome/do_upload
, and call the Welcome::do_upload()
method in another one by $this->do_upload()
.
Hence when you call the $this->do_upload();
within your second method, the $_FILES
array would be empty.
And that's why var_dump($data['upload_data']);
returns NULL
.
If you want to upload the file from welcome/second_method
, send the form request to the welcome/second_method where you call $this->do_upload();
.
Then change the form helper function (within the View) as follows1:
// Change the 'second_method' to your method name
echo form_open_multipart('welcome/second_method');
CodeIgniter has documented the Uploading process very well, by using the File Uploading library.
You could take a look at the sample code in the user guide; And also, in order to get a better understanding of the uploading configs, Check the Config items Explanation section at the end of the manual page.
Also there are couple of articles/samples about the file uploading in CodeIgniter, you might want to consider:
Just as a side-note: Make sure that you've loaded the url
and form
helper functions before using the CodeIgniter sample code:
// Load the helper files within the Controller
$this->load->helper('form');
$this->load->helper('url');
1. The form must be "multipart" type for file uploading. Hence you should use form_open_multipart()
helper function which returns:
<form method="post" action="controller/method" enctype="multipart/form-data" />
Just for someone looking for a solution more similar to R:
df[(df.Product == p_id) & (df.Time> start_time) & (df.Time < end_time)][['Time','Product']]
No need for data.loc
or query
, but I do think it is a bit long.
The obvious solution to developers familiar to Java is to use the LinkedList class already provided in java.util. Say, however, you wanted to make your own implementation for some reason. Here is a quick example of a linked list that inserts a new link at the beginning of the list, deletes from the beginning of the list and loops through the list to print the links contained in it. Enhancements to this implementation include making it a double-linked list, adding methods to insert and delete from the middle or end, and by adding get and sort methods as well.
Note: In the example, the Link object doesn't actually contain another Link object - nextLink is actually only a reference to another link.
class Link {
public int data1;
public double data2;
public Link nextLink;
//Link constructor
public Link(int d1, double d2) {
data1 = d1;
data2 = d2;
}
//Print Link data
public void printLink() {
System.out.print("{" + data1 + ", " + data2 + "} ");
}
}
class LinkList {
private Link first;
//LinkList constructor
public LinkList() {
first = null;
}
//Returns true if list is empty
public boolean isEmpty() {
return first == null;
}
//Inserts a new Link at the first of the list
public void insert(int d1, double d2) {
Link link = new Link(d1, d2);
link.nextLink = first;
first = link;
}
//Deletes the link at the first of the list
public Link delete() {
Link temp = first;
if(first == null){
return null;
//throw new NoSuchElementException(); // this is the better way.
}
first = first.nextLink;
return temp;
}
//Prints list data
public void printList() {
Link currentLink = first;
System.out.print("List: ");
while(currentLink != null) {
currentLink.printLink();
currentLink = currentLink.nextLink;
}
System.out.println("");
}
}
class LinkListTest {
public static void main(String[] args) {
LinkList list = new LinkList();
list.insert(1, 1.01);
list.insert(2, 2.02);
list.insert(3, 3.03);
list.insert(4, 4.04);
list.insert(5, 5.05);
list.printList();
while(!list.isEmpty()) {
Link deletedLink = list.delete();
System.out.print("deleted: ");
deletedLink.printLink();
System.out.println("");
}
list.printList();
}
}
This is a very old question, but i don't see my understanding here so I will add my 2 cents:
Every level corresponds/maps to a type of user:
You can do this with position:absolute;
on the #second
div like this :
CSS :
#wrapper{
position:relative;
}
#second {
position:absolute;
top:200px;
bottom:0;
left:0;
width:300px;
background-color:#9ACD32;
}
EDIT : Alternative solution
Depending on your layout and the content you have in those divs, you could make it much more simple and with less markup like this :
HTML :
<div id="wrapper">
<div id="first"></div>
</div>
CSS :
#wrapper {
height:100%;
width:300px;
background-color:#9ACD32;
}
#first {
background-color:#F5DEB3;
height: 200px;
}
The answers given so far are not ideal because they require a lot of needless work resolving merge conflicts, or they make too many assumptions which are frequently false. This is how to do it perfectly. The link is to my own site.
You have uncommited changes on my_branch
that you want to commit to master
, without committing all the changes from my_branch
.
git merge master
git stash -u
git checkout master
git stash apply
git reset
git add example.js
git commit
git checkout .
git clean -f -d
git checkout my_branch
git merge master
git stash pop
Start by merging master
into your branch, since you'll have to do that eventually anyway, and now is the best time to resolve any conflicts.
The -u
option (aka --include-untracked
) in git stash -u
prevents you from losing untracked files when you later do git clean -f -d
within master
.
After git checkout master
it is important that you do NOT git stash pop
, because you will need this stash later. If you pop the stash created in my_branch
and then do git stash
in master
, you will cause needless merge conflicts when you later apply that stash in my_branch
.
git reset
unstages everything resulting from git stash apply
. For example, files that have been modified in the stash but do not exist in master
get staged as "deleted by us" conflicts.
git checkout .
and git clean -f -d
discard everything that isn't committed: all changes to tracked files, and all untracked files and directories. They are already saved in the stash and if left in master
would cause needless merge conflicts when switching back to my_branch
.
The last git stash pop
will be based on the original my_branch
, and so will not cause any merge conflicts. However, if your stash contains untracked files which you have committed to master, git will complain that it "Could not restore untracked files from stash". To resolve this conflict, delete those files from your working tree, then git stash pop
, git add .
, and git reset
.
<script>
$('#btn_hide').click( function () {
$('#btn_hide').hide();
});
</script>
<input type="button" id="btn_hide"/>
this will be enough
With ASP.NET Web Pages you can do this on a single page as a basic GET example (the simplest possible thing that can work.
var json = Json.Encode(new {
orientation = Cache["orientation"],
alerted = Cache["alerted"] as bool?,
since = Cache["since"] as DateTime?
});
Response.Write(json);
You can absolutely do that, just remove the @RequestParam
annotation, Spring will cleanly bind your request parameters to your class instance:
public @ResponseBody List<MyObject> myAction(
@RequestParam(value = "page", required = false) int page,
MyObject myObject)
SELECT `locations`.`name`
FROM `locations`
INNER JOIN `school_locations`
ON `locations`.`id` = `school_locations`.`location_id`
INNER JOIN `schools`
ON `school_locations`.`school_id` = `schools_id`
WHERE `type` = 'coun';
the WHERE
clause has to be at the end of the statement
You can use the base64
module to encode strings to stop shoulder surfing, but it's not going to stop someone finding your code if they have access to your files.
You can then use the compile()
function and the eval()
function to execute your code once you've decoded it.
>>> import base64
>>> mycode = "print 'Hello World!'"
>>> secret = base64.b64encode(mycode)
>>> secret
'cHJpbnQgJ2hlbGxvIFdvcmxkICEn'
>>> mydecode = base64.b64decode(secret)
>>> eval(compile(mydecode,'<string>','exec'))
Hello World!
So if you have 30 lines of code you'll probably want to encrypt it doing something like this:
>>> f = open('myscript.py')
>>> encoded = base64.b64encode(f.read())
You'd then need to write a second script that does the compile()
and eval()
which would probably include the encoded script as a string literal encased in triple quotes. So it would look something like this:
import base64
myscript = """IyBUaGlzIGlzIGEgc2FtcGxlIFB5d
GhvbiBzY3JpcHQKcHJpbnQgIkhlbG
xvIiwKcHJpbnQgIldvcmxkISIK"""
eval(compile(base64.b64decode(myscript),'<string>','exec'))
You could try using MultiMap instead of HashMap
Initialising it will require fewer lines of codes. Adding and retrieving the values will also make it shorter.
Map<String, List<Integer>> map = new HashMap<String, List<Integer>>();
would become:
Multimap<String, Integer> multiMap = ArrayListMultimap.create();
You can check this link: http://java.dzone.com/articles/hashmap-%E2%80%93-single-key-and
var cumulativeOffset = function(element) {
var top = 0, left = 0;
do {
top += element.offsetTop || 0;
left += element.offsetLeft || 0;
element = element.offsetParent;
} while(element);
return {
top: top,
left: left
};
};
(Method shamelessly stolen from PrototypeJS; code style, variable names and return value changed to protect the innocent)
In newer version of git (2.23+) you can use:
git switch -C master origin/master
-C
is same as --force-create
. Related Reference Docs

//check in the depth of left and right subtree
int diff = depth(root.getLeft()) - depth(root.getRight());

return false;
}

Here is a solution which sorts the properties alphabetically and prints them all together with their values:
public void logProperties() throws IllegalArgumentException, IllegalAccessException {
Class<?> aClass = this.getClass();
Field[] declaredFields = aClass.getDeclaredFields();
Map<String, String> logEntries = new HashMap<>();
for (Field field : declaredFields) {
field.setAccessible(true);
Object[] arguments = new Object[]{
field.getName(),
field.getType().getSimpleName(),
String.valueOf(field.get(this))
};
String template = "- Property: {0} (Type: {1}, Value: {2})";
String logMessage = System.getProperty("line.separator")
+ MessageFormat.format(template, arguments);
logEntries.put(field.getName(), logMessage);
}
SortedSet<String> sortedLog = new TreeSet<>(logEntries.keySet());
StringBuilder sb = new StringBuilder("Class properties:");
Iterator<String> it = sortedLog.iterator();
while (it.hasNext()) {
String key = it.next();
sb.append(logEntries.get(key));
}
System.out.println(sb.toString());
}
you can loop through all attributes like you do with nodes
foreach (XmlNode item in node.ChildNodes)
{
// node stuff...
foreach (XmlAttribute att in item.Attributes)
{
// attribute stuff
}
}
Here's the solution I've come up with:
private static final Comparator<Integer> BY_ASCENDING_ORDER = Integer::compare;
private static final Comparator<Integer> BY_DESCENDING_ORDER = BY_ASCENDING_ORDER.reversed();
then using those comparators:
IntStream.range(-range, 0).boxed().sorted(BY_DESCENDING_ORDER).forEach(// etc...
Although sometimes I use gitg, always come back to command line:
[alias]
#quick look at all repo
loggsa = log --color --date-order --graph --oneline --decorate --simplify-by-decoration --all
#quick look at active branch (or refs pointed)
loggs = log --color --date-order --graph --oneline --decorate --simplify-by-decoration
#extend look at all repo
logga = log --color --date-order --graph --oneline --decorate --all
#extend look at active branch
logg = log --color --date-order --graph --oneline --decorate
#Look with date
logda = log --color --date-order --date=local --graph --format=\"%C(auto)%h%Creset %C(blue bold)%ad%Creset %C(auto)%d%Creset %s\" --all
logd = log --color --date-order --date=local --graph --format=\"%C(auto)%h%Creset %C(blue bold)%ad%Creset %C(auto)%d%Creset %s\"
#Look with relative date
logdra = log --color --date-order --graph --format=\"%C(auto)%h%Creset %C(blue bold)%ar%Creset %C(auto)%d%Creset %s\" --all
logdr = log --color --date-order --graph --format=\"%C(auto)%h%Creset %C(blue bold)%ar%Creset %C(auto)%d%Creset %s\"
loga = log --graph --color --decorate --all
# For repos without subject body commits (vim repo, git-svn clones)
logt = log --graph --color --format=\"%C(auto)%h %d %<|(100,trunc) %s\"
logta = log --graph --color --format=\"%C(auto)%h %d %<|(100,trunc) %s\" --all
logtsa = log --graph --color --format=\"%C(auto)%h %d %<|(100,trunc) %s\" --all --simplify-by-decoration
As you can see is almost a keystroke saving aliases, based on:
See in recent version of git (1.8.5 and above) you can benefit from %C(auto) in decorate placeholder %d
From here all you need is a good understand of gitrevisions to filter whatever you need (something like master..develop, where --simplify-merges could help with long term branches)
The power behind command line is the quickly config based on your needs (understand a repo isn't a unique key log configuration, so adding --numstat, or --raw, or --name-status is sometimes needed. Here git log and aliases are fast, powerful and (with time) the prettiest graph you can achieved. Even more, with output showed by default through a pager (say less) you can always search quickly inside results. Not convinced? You can always parse the result with projects like gitgraph
It isn't exactly defined as zero per se, it's defined as Calendar.January. It is the problem of using ints as constants instead of enums. Calendar.January == 0.
In ImageMagick, you can do "supersampling". You specify a large density and then resize down as much as desired for the final output size. For example with your image:
convert -density 600 test.pdf -background white -flatten -resize 25% test.png

I do not recommend saving to JPG if you are expecting to do further processing.
If you want the output to be the same size as the input, then resize to the inverse of the ratio of your density to 72. For example, -density 288 and -resize 25%. 288=4*72 and 25%=1/4
The larger the density the better the resulting quality, but it will take longer to process.
There is no need to use the classpath: protocol in your schemaLocation URL if the namespace is configured correctly and the XSD file is on your classpath.
Spring doc "Registering the handler and the schema" shows how it should be done.
In your case, the problem was probably that the spring-context jar on your classpath was not 2.1. That was why changing the protocol to classpath: and putting the specific 2.1 XSD in your classpath fixed the problem.
From what I've seen, there are 2 schemas defined for the main XSD contained in a spring-* jar. Once to resolve the schema URL with the version and once without it.
As an example see this part of the spring.schemas contents in spring-context-3.0.5.RELEASE.jar:
http\://www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd
http\://www.springframework.org/schema/context/spring-context-3.0.xsd=org/springframework/context/config/spring-context-3.0.xsd
http\://www.springframework.org/schema/context/spring-context.xsd=org/springframework/context/config/spring-context-3.0.xsd
This means that (in xsi:schemaLocation)
http://www.springframework.org/schema/context/spring-context-2.5.xsd
will be validated against
org/springframework/context/config/spring-context-2.5.xsd
in the classpath.
http://www.springframework.org/schema/context/spring-context-3.0.xsd
or
http://www.springframework.org/schema/context/spring-context.xsd
will be validated against
org/springframework/context/config/spring-context-3.0.xsd
in the classpath.
http://www.springframework.org/schema/context/spring-context-2.1.xsd
is not defined so Spring will look for it using the literal URL defined in schemaLocation.
I have solved my problem, my 'task' is under a python package named 'celery_task',when i quit this package,and run the command celery worker -A celery_task.task --loglevel=info
. It works.
Relational databases have a mathematical basis (set theory, relational theory), which are distilled into SQL == Structured Query Language.
NoSQL's many forms (e.g. document-based, graph-based, object-based, key-value store, etc.) may or may not be based on a single underpinning mathematical theory. As S. Lott has correctly pointed out, hierarchical data stores do indeed have a mathematical basis. The same might be said for graph databases.
I'm not aware of a universal query language for NoSQL databases.
You're reading the entire file into memory (line = u.readlines()
) which will fail of course if the file is too large (and you say that some are up to 20 GB), so that's your problem right there.
Better iterate over each line:
for current_line in u:
do_something_with(current_line)
is the recommended approach.
Later in your script, you're doing some very strange things like first counting all the items in a list, then constructing a for
loop over the range of that count. Why not iterate over the list directly? What is the purpose of your script? I have the impression that this could be done much easier.
This is one of the advantages of high-level languages like Python (as opposed to C where you do have to do these housekeeping tasks yourself): Allow Python to handle iteration for you, and only collect in memory what you actually need to have in memory at any given time.
Also, as it seems that you're processing TSV files (tabulator-separated values), you should take a look at the csv
module which will handle all the splitting, removing of \n
s etc. for you.

Postgres variables are created through the \set command, for example ...
\set myvariable value
... and can then be substituted, for example, as ...
SELECT * FROM :myvariable.table1;
... or ...
SELECT * FROM table1 WHERE :myvariable IS NULL;
edit: As of psql 9.1, variables can be expanded in quotes as in:
\set myvariable value
SELECT * FROM table1 WHERE column1 = :'myvariable';
In older versions of the psql client:
... If you want to use the variable as the value in a conditional string query, such as ...
SELECT * FROM table1 WHERE column1 = ':myvariable';
... then you need to include the quotes in the variable itself as the above will not work. Instead define your variable as such ...
\set myvariable 'value'
However, if, like me, you ran into a situation in which you wanted to make a string from an existing variable, I found the trick to be this ...
\set quoted_myvariable '\'' :myvariable '\''
Now you have both a quoted and unquoted variable of the same string! And you can do something like this ....
INSERT INTO :myvariable.table1 SELECT * FROM table2 WHERE column1 = :quoted_myvariable;

public void setTabTextColors(int normalColor, int selectedColor) {
setTabTextColors(createColorStateList(normalColor, selectedColor));
}
So, we just say
mycooltablayout.setTabTextColors(Color.parseColor("#1464f4"), Color.parseColor("#880088"));
That will give us a blue normal color and purple selected color.
Now we set the height
public void setSelectedTabIndicatorHeight(int height) {
mTabStrip.setSelectedIndicatorHeight(height);
}
And for height we say
mycooltablayout.setSelectedIndicatorHeight(6);
Travis-ci and Jenkins, while both are tools for continuous integration are very different.
Travis is a hosted service (free for open source) while you have to host, install and configure Jenkins.
Travis does not have jobs as in Jenkins. The commands to run to test the code are taken from a file named .travis.yml
which sits along your project code. This makes it easy to have different test code per branch since each branch can have its own version of the .travis.yml file.
You can have a similar feature with Jenkins if you use one of the following plugins:
.jervis.yml
file found at the root of project code. If .jervis.yml
does not exist, it will fall back to using .travis.yml
file instead.There are other hosted services you might also consider for continuous integration (non exhaustive list):
You might want to stay with Jenkins because you are familiar with it or don't want to depend on 3rd party for your continuous integration system. Else I would drop Jenkins and go with one of the free hosted CI services as they save you a lot of trouble (host, install, configure, prepare jobs)
Depending on where your code repository is hosted I would make the following choices:
To setup Travis-CI on a github project, all you have to do is:
The features you get are:
I forgot to mention. This should also accept whitespace.
You could use:
/^[-@.\/#&+\w\s]*$/
Note how this makes use of the character classes \w
and \s
.
EDIT:- Added \ to escape /
Because break can only be used inside a loop. It is used to break out of a loop (stop the loop).
You can use the following script if you don't wish to use Wizard;

You can use import data with wizard and there you can choose destination table.
Run the wizard. In selecting source tables and views window you see two parts. Source and Destination.
Click on the field under Destination part to open the drop down and select you destination table and edit its mappings if needed.
EDIT
Merely typing the name of the table does not work. It appears that the name of the table must include the schema (dbo
) and possibly brackets. Note the dropdown on the right hand side of the text field.
I know this is old, but I thought it might be helpful to show what these functions look like in code. This really illustrates the logic, better than text or a table IMO. In reality they are implemented in C rather than pure Python, but these are equivalent.
def any(iterable):
for item in iterable:
if item:
return True
return False
def all(iterable):
for item in iterable:
if not item:
return False
return True
In particular, you can see that the result for empty iterables is just the natural result, not a special case. You can also see the short-circuiting behaviour; it would actually be more work for there not to be short-circuiting.
When Guido van Rossum (the creator of Python) first proposed adding any()
and all()
, he explained them by just posting exactly the above snippets of code.
This is an example of "if else" with actions.
>>> def fun(num):
print 'This is %d' % num
>>> fun(10) if 10 > 0 else fun(2)
this is 10
OR
>>> fun(10) if 10 < 0 else 1
1

A simple dictionary:
x = {'X':"yes", 'Y':"no", 'Z':"ok"}
To print a specific (key, value) pair in Python 3 (pair at index 1 in this example):
for e in range(len(x)):
print(([x for x in x.keys()][e], [x for x in x.values()][e]))
Output:
('X', 'yes')
('Y', 'no')
('Z', 'ok')
Here is a one liner solution to print all pairs in a tuple:
print(tuple(([x for x in x.keys()][i], [x for x in x.values()][i]) for i in range(len(x))))
Output:
(('X', 'yes'), ('Y', 'no'), ('Z', 'ok'))
CTRL+SHIFT+I brings up the developers tools.
You can use explode
for separating the namespace and end
to get the class name:
$ex = explode("\\", get_class($object));
$className = end($ex);
Following method is deprecated
sslSocketFactory(SSLSocketFactory sslSocketFactory)
Consider updating it to
sslSocketFactory(SSLSocketFactory sslSocketFactory, X509TrustManager trustManager)
The main rule here is that:
The selectors which are applicable during compilation of a component template are determined by the module that declares that component, and the transitive closure of the exports of that module's imports.
So, try to export it:
@NgModule({
declarations: [TaskCardComponent],
imports: [MdCardModule],
exports: [TaskCardComponent] <== this line
})
export class TaskModule{}
What should I export?
Export declarable classes that components in other modules should be able to reference in their templates. These are your public classes. If you don't export a class, it stays private, visible only to other component declared in this module.
The minute you create a new module, lazy or not, any new module and you declare anything into it, that new module has a clean state(as Ward Bell said in https://devchat.tv/adv-in-angular/119-aia-avoiding-common-pitfalls-in-angular2)
Angular creates transitive module for each of @NgModule
s.
This module collects directives that either imported from another module(if transitive module of imported module has exported directives) or declared in current module.
When angular compiles template that belongs to module X
it is used those directives that had been collected in X.transitiveModule.directives.
compiledTemplate = new CompiledTemplate(
false, compMeta.type, compMeta, ngModule, ngModule.transitiveModule.directives);
https://github.com/angular/angular/blob/4.2.x/packages/compiler/src/jit/compiler.ts#L250-L251
This way according to the picture above
YComponent
can't use ZComponent
in its template because directives
array of Transitive module Y
doesn't contain ZComponent
because YModule
has not imported ZModule
whose transitive module contains ZComponent
in exportedDirectives
array.
Within XComponent
template we can use ZComponent
because Transitive module X
has directives array that contains ZComponent
because
XModule
imports module (YModule
) that exports module (ZModule
) that exports directive ZComponent
Within AppComponent
template we can't use XComponent
because AppModule
imports XModule
but XModule
doesn't exports XComponent
.

Your postgres server configuration seems correct
That should grant access from the client to the postgres server. So that leads me to believe the username / password is whats failing.
host all all 127.0.0.1/32 md5
host all all 192.168.0.1/32 trust
Test this by creating a specific user for that database
createuser -a -d -W -U postgres chaosuser
Then adjust your perl script to use the newly created user
my $dbh = DBI->connect("DBI:PgPP:database=chaosLRdb;host=192.168.0.1;port=5433", "chaosuser", "chaos123");
My preference, and I have no idea why this isn't already in jQuery:
$.fn.orElse = function(elseFunction) {
if (!this.length) {
elseFunction();
}
};
Used like this:
$('#notAnElement').each(function () {
alert("Wrong, it is an element")
}).orElse(function() {
alert("Yup, it's not an element")
});
Or, as it looks in CoffeeScript:
$('#notAnElement').each ->
alert "Wrong, it is an element"; return
.orElse ->
alert "Yup, it's not an element"

Some receivers expect EOL sequence, which is typically two characters \r\n
, so try in your code replace the line
unsigned char cmd[] = {'I', 'N', 'I', 'T', ' ', '\r', '\0'};
with
unsigned char cmd[] = "INIT\r\n";
BTW, the above way is probably more efficient. There is no need to quote every character.
This is the way I would do it : saying that "list" is a <List<t>>
where t is a class with a Name and a Value field; but of course you can do it with any other class type.
list = list.Where(c=>c.Name == "height")
.Select( new t(){Name = c.Name, Value = 30})
.Union(list.Where(c=> c.Name != "height"))
.ToList();
This works perfectly ! It's a simple linq expression without any loop logic. The only thing you should be aware is that the order of the lines in the result dataset will be different from the order you had in the source dataset. So if sorting is important to you, just reproduce the same order by clauses in the final linq query.
Yes, O3 is buggier. I'm a compiler developer and I've identified clear and obvious gcc bugs caused by O3 generating buggy SIMD assembly instructions when building my own software. From what I've seen, most production software ships with O2 which means O3 will get less attention wrt testing and bug fixes.
Think of it this way: O3 adds more transformations on top of O2, which adds more transformations on top of O1. Statistically speaking, more transformations means more bugs. That's true for any compiler.

When you visited https://localhost previously at some point it not only visited this over a secure channel (https rather than http), it also told your browser, using a special HTTP header: Strict-Transport-Security (often abbreviated to HSTS), that it should ONLY use https for all future visits.
This is a security feature web servers can use to prevent people being downgraded to http (either intentionally or by some evil party).
However if you then then turn off your https server, and just want to browse http you can't (by design - that's the point of this security feature).
HSTS also does prevents you from accepting and skipping past certificate errors.
To reset this, so HSTS is no longer set for localhost, type the following in your Chrome address bar:
chrome://net-internals/#hsts
Where you will be able to delete this setting for "localhost".
You might also want to find out what was setting this to avoid this problem in future!
Note that for other sites (e.g. www.google.com) these are "preloaded" into the Chrome code and so cannot be removed. When you query them at chrome://net-internals/#hsts you will see them listed as static
HSTS entries.
And finally note that Google has started preloading HSTS for the entire .dev domain: https://ma.ttias.be/chrome-force-dev-domains-https-via-preloaded-hsts/
You don't need an extra table row to create space inside a table. See this jsFiddle.

Using a table row just for display purposes is table abuse!

Choosing older simulator versions is not obvious in Xcode 3.2.5. Older Xcodes had separate lists of "iOS Device SDKs" and "iOS Simulator SDKs" in the "Base SDK" build setting popup menu, but in Xcode 3.2.5 these have been replaced with a single "iOS SDKs" list that only offers 4.2 and "latest".
If you create a new default iOS project, it defaults to 4.2 for both Base SDK and Deployment Target, and in the "Overview" popup in the project's top-left corner, only the 4.2 Simulator is available.
To run an older iOS simulator, you must choose an older iOS version in the "iOS Deployment Target" build setting popup. Only then will the "Overview" popup offer older Simulators: back to 4.0 for iPhone and to 3.2 for iPad.
This could be more helpfull....

As you can see, the AND operator drops every row in which at least one value equals -1. On the other hand, the OR operator requires both values to be equal to -1 to drop them.
That's right. Remember that you're writing the condition in terms of what you want to keep, not in terms of what you want to drop. For df1
:
df1 = df[(df.a != -1) & (df.b != -1)]
You're saying "keep the rows in which df.a
isn't -1 and df.b
isn't -1", which is the same as dropping every row in which at least one value is -1.
For df2
:
df2 = df[(df.a != -1) | (df.b != -1)]
You're saying "keep the rows in which either df.a
or df.b
is not -1", which is the same as dropping rows where both values are -1.
PS: chained access like df['a'][1] = -1
can get you into trouble. It's better to get into the habit of using .loc
and .iloc
.
You cannot add a ListView in a scroll View, as list view also scolls and there would be a synchonization problem between listview scroll and scroll view scoll. You can make a CustomList View and add this method into it.

/*

if (p != null) {
p.requestDisallowInterceptTouchEvent(true);
}
}
return false;

You can not sort TreeMap on values.
A Red-Black tree based NavigableMap implementation. The map is sorted according to the natural ordering of its keys, or by a Comparator provided at map creation time, depending on which constructor is used You will need to provide
comparator
forComparator<? super K>
so your comparator should compare on keys.
To provide sort on values you will need SortedSet. Use
SortedSet<Map.Entry<String, Double>> sortedset = new TreeSet<Map.Entry<String, Double>>(
new Comparator<Map.Entry<String, Double>>() {
@Override
public int compare(Map.Entry<String, Double> e1,
Map.Entry<String, Double> e2) {
return e1.getValue().compareTo(e2.getValue());
}
});
sortedset.addAll(myMap.entrySet());
To give you an example
SortedMap<String, Double> myMap = new TreeMap<String, Double>();
myMap.put("a", 10.0);
myMap.put("b", 9.0);
myMap.put("c", 11.0);
myMap.put("d", 2.0);
sortedset.addAll(myMap.entrySet());
System.out.println(sortedset);
Output:
[d=2.0, b=9.0, a=10.0, c=11.0]
Firstly, thanks to Andrei as I've based my solution on his example.
I'm including mine as it's a more complete sample and might save readers some time.
The limitation of Andrei's approach is that doesn't handle logging, capturing potentially useful request variables and content negotiation (it will always return JSON no matter what the client has requested - XML / plain text etc).
My approach is to use an ObjectResult which allows us to use the functionality baked into MVC.
This code also prevents caching of the response.
The error response has been decorated in such a way that it can be serialized by the XML serializer.
public class ExceptionHandlerMiddleware
{
private readonly RequestDelegate next;
private readonly IActionResultExecutor<ObjectResult> executor;
private readonly ILogger logger;
private static readonly ActionDescriptor EmptyActionDescriptor = new ActionDescriptor();
public ExceptionHandlerMiddleware(RequestDelegate next, IActionResultExecutor<ObjectResult> executor, ILoggerFactory loggerFactory)
{
this.next = next;
this.executor = executor;
logger = loggerFactory.CreateLogger<ExceptionHandlerMiddleware>();
}
public async Task Invoke(HttpContext context)
{
try
{
await next(context);
}
catch (Exception ex)
{
logger.LogError(ex, $"An unhandled exception has occurred while executing the request. Url: {context.Request.GetDisplayUrl()}. Request Data: " + GetRequestData(context));
if (context.Response.HasStarted)
{
throw;
}
var routeData = context.GetRouteData() ?? new RouteData();
ClearCacheHeaders(context.Response);
var actionContext = new ActionContext(context, routeData, EmptyActionDescriptor);
var result = new ObjectResult(new ErrorResponse("Error processing request. Server error."))
{
StatusCode = (int) HttpStatusCode.InternalServerError,
};
await executor.ExecuteAsync(actionContext, result);
}
}
private static string GetRequestData(HttpContext context)
{
var sb = new StringBuilder();
if (context.Request.HasFormContentType && context.Request.Form.Any())
{
sb.Append("Form variables:");
foreach (var x in context.Request.Form)
{
sb.AppendFormat("Key={0}, Value={1}<br/>", x.Key, x.Value);
}
}
sb.AppendLine("Method: " + context.Request.Method);
return sb.ToString();
}
private static void ClearCacheHeaders(HttpResponse response)
{
response.Headers[HeaderNames.CacheControl] = "no-cache";
response.Headers[HeaderNames.Pragma] = "no-cache";
response.Headers[HeaderNames.Expires] = "-1";
response.Headers.Remove(HeaderNames.ETag);
}
[DataContract(Name= "ErrorResponse")]
public class ErrorResponse
{
[DataMember(Name = "Message")]
public string Message { get; set; }
public ErrorResponse(string message)
{
Message = message;
}
}
}
Try this:

There are pros and cons to the last two solutions posted, but they're both IMHO great solutions.
You may or may not want your session ID embedded in your url like that for tighter security. But in development that shouldn't matter, but what if you forget to remove it? Also does that really work? Wouldn't you need something like a sequential number generator (hit count stored in the session, or maybe even just if 1 then 0, if 0 then 1)?
Adding a session id (or whatever sequencer) means you need to remember to add it to every resource you don't want cached. On the one hand that's better because you can just include your session id with just that resource you're actively developing and testing. On the other hand, it means you have to do that and you have to remember to remove that for production.
Modifying the vhost.conf or the .htaccess file does the trick nicely without the need to remember to add and remove the session id. But the downside is performance of all js and css resources will be affected, and if you have large files, that's going to slow you down.
Both seem like great, elegant solutions -- depends on your needs.
You need to have the testng.jar
under classpath.
try C:\projectfred> java -cp "path-tojar/testng.jar:path_to_yourtest_classes" org.testng.TestNG testng.xml
Update:
Under linux I ran this command and it would be some thing similar on Windows either
test/bin# java -cp ".:../lib/*" org.testng.TestNG testng.xml
Directory structure:
/bin - All my test packages are under bin including testng.xml
/src - All source files are under src
/lib - All libraries required for the execution of tests are under this.
Once I compile all sources they go under bin directory. So, in the classpath I need to specify contents of bin directory and all the libraries like testng.xml, loggers etc over here. Also copy testng.xml to bin folder if you dont want to specify the full path where the testng.xml is available.
/bin
-- testng.xml
-- testclasses
-- Properties files if any.
/lib
-- testng.jar
-- log4j.jar
Update
:
Go to the folder MyProject
and type run the java command like the way shown below:-
java -cp ".: C:\Program Files\jbdevstudio4\studio\plugins\*" org.testng.TestNG testng.xml
I believe the testng.xml file is under C:\Users\me\workspace\MyProject
if not please give the full path for testng.xml
file
Every function inside a class, and every class variable must take the self argument as pointed.
class mystuff:
def average(a,b,c): #get the average of three numbers
result=a+b+c
result=result/3
return result
def sum(self,a,b):
return a+b
print mystuff.average(9,18,27) # should raise error
print mystuff.sum(18,27) # should be ok
If class variables are involved:
class mystuff:
def setVariables(self,a,b):
self.x = a
self.y = b
return a+b
def mult(self):
return x * y # This line will raise an error
def sum(self):
return self.x + self.y
print mystuff.setVariables(9,18) # Setting mystuff.x and mystuff.y
print mystuff.mult() # should raise error
print mystuff.sum() # should be ok
Hi another solution to this problem is to simply add the node nodejs binary folder to your PATH using the following command:
ln -s /usr/bin/nodejs /usr/bin/node
See NPM GitHub for better explanation
A simple way using std::next_permutation
:
#include <iostream>
#include <algorithm>
#include <vector>
int main() {
int n, r;
std::cin >> n;
std::cin >> r;
std::vector<bool> v(n);
std::fill(v.end() - r, v.end(), true);
do {
for (int i = 0; i < n; ++i) {
if (v[i]) {
std::cout << (i + 1) << " ";
}
}
std::cout << "\n";
} while (std::next_permutation(v.begin(), v.end()));
return 0;
}
or a slight variation that outputs the results in an easier to follow order:
#include <iostream>
#include <algorithm>
#include <vector>
int main() {
int n, r;
std::cin >> n;
std::cin >> r;
std::vector<bool> v(n);
std::fill(v.begin(), v.begin() + r, true);
do {
for (int i = 0; i < n; ++i) {
if (v[i]) {
std::cout << (i + 1) << " ";
}
}
std::cout << "\n";
} while (std::prev_permutation(v.begin(), v.end()));
return 0;
}
A bit of explanation:
It works by creating a "selection array" (v
), where we place r
selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v
.
You can implement it if you note that for each level r you select a number from 1 to n.
In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance
#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>
using namespace std;
struct combinations
{
typedef vector<int> combination_t;
// initialize status
combinations(int N, int R) :
completed(N < 1 || R > N),
generated(0),
N(N), R(R)
{
for (int c = 1; c <= R; ++c)
curr.push_back(c);
}
// true while there are more solutions
bool completed;
// count how many generated
int generated;
// get current and compute next combination
combination_t next()
{
combination_t ret = curr;
// find what to increment
completed = true;
for (int i = R - 1; i >= 0; --i)
if (curr[i] < N - R + i + 1)
{
int j = curr[i] + 1;
while (i <= R-1)
curr[i++] = j++;
completed = false;
++generated;
break;
}
return ret;
}
private:
int N, R;
combination_t curr;
};
int main(int argc, char **argv)
{
int N = argc >= 2 ? atoi(argv[1]) : 5;
int R = argc >= 3 ? atoi(argv[2]) : 2;
combinations cs(N, R);
while (!cs.completed)
{
combinations::combination_t c = cs.next();
copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
cout << endl;
}
return cs.generated;
}
test output:

I want to add on this that you can also get Hibernate's session by calling getDelegate()
method from EntityManager
.
ex:
Session session = (Session) entityManager.getDelegate();
If it is just avoiding the exception you are worried about, the "find_all_by.." family of functions works without throwing exceptions.
Comment.find_all_by_id([2, 3, 5])
will work even if some of the ids don't exist. This works in the
user.comments.find_all_by_id(potentially_nonexistent_ids)
case as well.
Comment.where(id: [2, 3, 5])
I am giving one exapmle to undersand when do we use @Queryparam
and @pathparam
For example I am taking one resouce is carResource
class
If you want to make the inputs of your resouce method manadatory then use the param type as @pathaparam
, if the inputs of your resource method should be optional then keep that param type as @QueryParam
param
@Path("/car")
class CarResource
{
@Get
@produces("text/plain")
@Path("/search/{carmodel}")
public String getCarSearch(@PathParam("carmodel")String model,@QueryParam("carcolor")String color) {
//logic for getting cars based on carmodel and color
-----
return cars
}
}
For this resouce pass the request
req uri ://address:2020/carWeb/car/search/swift?carcolor=red
If you give req like this the resouce will gives the based car model and color
req uri://address:2020/carWeb/car/search/swift
If you give req like this the resoce method will display only swift model based car
req://address:2020/carWeb/car/search?carcolor=red
If you give like this we will get ResourceNotFound exception because in the car resouce class I declared carmodel as @pathPram
that is you must and should give the carmodel as reQ uri otherwise it will not pass the req to resouce but if you don't pass the color also it will pass the req to resource why because the color is @quetyParam
it is optional in req.
You can try disabling selinux and try once again using the following command

%s
indicates a conversion type of string when using python's string formatting capabilities. More specifically, %s
converts a specified value to a string using the str()
function. Compare this with the %r
conversion type that uses the repr()
function for value conversion.
Take a look at the docs for string formatting.
Well to obtain all different values in a Dataframe
you can use distinct. As you can see in the documentation that method returns another DataFrame
. After that you can create a UDF
in order to transform each record.
For example:
val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")
// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct
// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)
// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))
use this
<div ng-class="{states}[condition]"></div>
for example if the condition is [2 == 2], states are {true: '...', false: '...'}
<div ng-class="{true: 'ClassA', false: 'ClassB'}[condition]"></div>
To install within your Docker container you can run command
docker exec apt-get update && apt-get install -y vim
But this will be limited to the container in which vim is installed. To make it available to all the containers, edit the Dockerfile and add
RUN apt-get update && apt-get install -y vim
or you can also extend the image in the new Dockerfile and add above command. Eg.
FROM < image name >
RUN apt-get update && apt-get install -y vim
This the simplest way to assign an async
arrow function expression to a named variable:
const foo = async () => {
// do something
}
(Note that this is not strictly equivalent to async function foo() { }
. Besides the differences between the function
keyword and an arrow expression, the function in this answer is not "hoisted to the top".)

Solution in Android Java:
Start your EditText, the ID is come to your xml id.
EditText myText = (EditText)findViewById(R.id.my_text_id);
in your OnCreate Method, just set the text by the name defined.
String text = "here put the text that you want"
use setText method from your editText.
myText.setText(text); //variable from point 2
Rather than using a DisplayFilter you could use a very simple CaptureFilter like
port 53
See the "Capture only DNS (port 53) traffic" example on the CaptureFilters wiki.
For completeness I'll mention that Powershell 3.0 now has a -Tail flag on Get-Content
Get-Content ./log.log -Tail 10
gets the last 10 lines of the file
Get-Content ./log.log -Wait -Tail 10
gets the last 10 lines of the file and waits for more
Also, for those *nix users, note that most systems alias cat to Get-Content, so this usually works
cat ./log.log -Tail 10
In .NET 5, a new class has been introduced called JsonContent
, which derives from HttpContent
. See in Microsoft docs
This class has a static method called Create()
, which takes an object as a parameter.
Usage:
var myObject = new
{
foo = "Hello",
bar = "World",
};
JsonContent content = JsonContent.Create(myObject);
HttpResponseMessage response = await _httpClient.PostAsync("https://...", content);
By checking out to one of the commits in the history you are moving your git into so called 'detached state', which looks like is not what you want. Use this single command to create a new branch on one of the commits from the history:
git checkout -b <new_branch_name> <SHA1>
Correct, file handle 1 for the process is STDOUT, redirected by the 1>
or by >
(1 can be omitted, by convention, the command interpreter [cmd.exe] knows to handle that).
File handle 2 is STDERR, redirected by 2>
.
Note that if you're using these to make log files, then unless you're sending the outut to _uniquely_named_ (eg date-and-time-stamped) log files, then if you run the same process twice, the redirected will overwrite (replace) the previous log file.
The >>
(for either STDOUT or STDERR) will APPEND not REPLACE the file. So you get a cumulative logfile, showwing the results from all runs of the process - typically more useful.
Happy trails...
I'm sure you know that a std::vector<X>
stores a whole bunch of X
objects, right? But if you have a std::map<X, Y>
, what it actually stores is a whole bunch of std::pair<const X, Y>
s. That's exactly what a map is - it pairs together the keys and the associated values.
When you iterate over a std::map
, you're iterating over all of these std::pair
s. When you dereference one of these iterators, you get a std::pair
containing the key and its associated value.
std::map<std::string, int> m = /* fill it */;
auto it = m.begin();
Here, if you now do *it
, you will get the the std::pair
for the first element in the map.
Now the type std::pair
gives you access to its elements through two members: first
and second
. So if you have a std::pair<X, Y>
called p
, p.first
is an X
object and p.second
is a Y
object.
So now you know that dereferencing a std::map
iterator gives you a std::pair
, you can then access its elements with first
and second
. For example, (*it).first
will give you the key and (*it).second
will give you the value. These are equivalent to it->first
and it->second
.
You can chain class selectors without a space between them:
.a.b {
color: #666;
}
Note that, if it matters to you, IE6 treats .a.b
as .b
, so in that browser both div.a.b
and div.b
will have gray text. See this answer for a comparison between proper browsers and IE6.
More clear query, targeting Studio sql queries is :
SELECT text FROM sys.dm_exec_sessions es
INNER JOIN sys.dm_exec_connections ec
ON es.session_id = ec.session_id
CROSS APPLY sys.dm_exec_sql_text(ec.most_recent_sql_handle)
where program_name like '%Query'
You can fix this easily with jQuery - and a little ugly hack :-)
I have a asp.net page with a ReportViewer user control.
<rsweb:ReportViewer ID="ReportViewer1" runat="server"...
In the document ready event I then start a timer and look for the element which needs the overflow fix (as previous posts):
<script type="text/javascript">
$(function () {
// Bug-fix on Chrome and Safari etc (webkit)
if ($.browser.webkit) {
// Start timer to make sure overflow is set to visible
setInterval(function () {
var div = $('#<%=ReportViewer1.ClientID %>_fixedTable > tbody > tr:last > td:last > div')
div.css('overflow', 'visible');
}, 1000);
}
});
</script>
Better than assuming it has a certain id. You can adjust the timer to whatever you like. I set it to 1000 ms here.
Sprint == Iteration.
The lengths can vary, but it's a bad planning precedent to let them vary too much.
Keep them consistent in duration and you will get better at planning and delivering. Everything will be measured by how many 10-day sprints it takes to finish a series of use cases.
Keep them consistent in length and you can plan your deliveries, end-user testing, etc., with more accuracy.
The point is to release on time at a consistent pace. A regular schedule makes management slightly simpler and more predictable.
EXEC sp_helplogins
You can also pass an "@LoginNamePattern" parameter to get information about a specific login:
EXEC sp_helplogins @LoginNamePattern='fred'
You could use a List<T>
and when T
is a value type it will be allocated in contiguous memory which would not be the case if T
is a reference type.
Example:
List<int> integers = new List<int>();
integers.Add(1);
integers.Add(4);
integers.Add(7);
int someElement = integers[1];
Going down your list:
Utf32String
class as part of my MiscUtil library, should you ever want it. (It's not been very thoroughly tested, mind you.)There's more on my Unicode page and tips for debugging Unicode problems.
The other big resource of code is unicode.org which contains more information than you'll ever be able to work your way through - possibly the most useful bit is the code charts.
This works with Swift 3.1.1 on Linux:
import Foundation
let s = try! String(contentsOfFile: "yo", encoding: .utf8)
Everyone here is focusing on downgrading @angular-devkit/build-angular to @angular 7.x versions for compatibility, but what they should be doing is to upgrade @angular/cli
to angular 8 versions.
The problem is that the system cli is still stuck at an old version and isn't automatically updated by ng update
(because it is outside the angular controlled project), so it is being left at an incompatible version when trying to access the angular libraries.
Downgrading @angular-devkit/build-angular
just causes more incompatibilities.
npm i --global @angular/cli@latest
will fix the problem without breaking things elsewhere.
Put [] around any field names that had spaces (as Dreden says) and save your query, close it and reopen it.
Using Access 2016, I still had the error message on new queries after I added [] around any field names... until the Query was saved.
Once the Query is saved (and visible in the Objects' List), closed and reopened, the error message disappears. This seems to be a bug from Access.

A useful extension is to collect the results in a Dictionary
for fast lookup (e.g. in a loop):
var resultDict = _dbContext.Projects
.Where(p => p.Status == ProjectStatus.Active)
.GroupBy(f => f.Country)
.Select(g => new { country = g.Key, count = g.Count() })
.ToDictionary(k => k.country, i => i.count);

cv2
uses numpy
for manipulating images, so the proper and best way to get the size of an image is using numpy.shape
. Assuming you are working with BGR images, here is an example:
>>> import numpy as np
>>> import cv2
>>> img = cv2.imread('foo.jpg')
>>> height, width, channels = img.shape
>>> print height, width, channels
600 800 3
In case you were working with binary images, img
will have two dimensions, and therefore you must change the code to: height, width = img.shape
xlrd/xlwt (standard): Python does not have this functionality in it's standard library, but I think of xlrd/xlwt as the "standard" way to read and write excel files. It is fairly easy to make a workbook, add sheets, write data/formulas, and format cells. If you need all of these things, you may have the most success with this library. I think you could choose openpyxl instead and it would be quite similar, but I have not used it.
To format cells with xlwt, define a XFStyle
and include the style when you write to a sheet. Here is an example with many number formats. See example code below.
Tablib (powerful, intuitive): Tablib is a more powerful yet intuitive library for working with tabular data. It can write excel workbooks with multiple sheets as well as other formats, such as csv, json, and yaml. If you don't need formatted cells (like background color), you will do yourself a favor to use this library, which will get you farther in the long run.
csv (easy): Files on your computer are either text or binary. Text files are just characters, including special ones like newlines and tabs, and can be easily opened anywhere (e.g. notepad, your web browser, or Office products). A csv file is a text file that is formatted in a certain way: each line is a list of values, separated by commas. Python programs can easily read and write text, so a csv file is the easiest and fastest way to export data from your python program into excel (or another python program).
Excel files are binary and require special libraries that know the file format, which is why you need an additional library for python, or a special program like Microsoft Excel, Gnumeric, or LibreOffice, to read/write them.
import xlwt
style = xlwt.XFStyle()
style.num_format_str = '0.00E+00'
...
for i,n in enumerate(list1):
sheet1.write(i, 0, n, fmt)
If you need to interact directly with the DOM element, why not just use document.getElementById
since, if you are trying to interact with a specific element you will probably know the id, as assuming that the classname is on only one element or some other option tends to be risky.
But, I tend to agree with the others, that in most cases you should learn to do what you need using what jQuery gives you, as it is very flexible.
UPDATE: Based on a comment: Here is a post with a nice explanation: http://www.mail-archive.com/[email protected]/msg04461.html
$(this).attr("checked") ? $(this).val() : 0
This will return the value if it's checked, or 0 if it's not.
$(this).val()
is just reaching into the dom and getting the attribute "value" of the element, whether or not it's checked.
If you are using Mercurial, this is done via "import". So at the command line, the hg import
command, or (you may find the --no-commit
option useful), or "Repository" => "Import..." in Hg Workbench.
Note that these will commit the changes by default; you can avoid this using hg import --no-commit
option if using the command-line, or if you used Hg Workbench, you might find it useful to issue hg rollback
after the merge.
Take a look at this for more detail. It refers to how Apache handles multiple requests. Preforking, which is the default, starts a number of Apache processes (2 by default here, though I believe one can configure this through httpd.conf). Worker MPM will start a new thread per request, which I would guess, is more memory efficient. Historically, Apache has used prefork, so it's a better-tested model. Threading was only added in 2.0.
One way to do this is to insert a dummy column with the sums in order to sort:
In [10]: sum_B_over_A = df.groupby('A').sum().B
In [11]: sum_B_over_A
Out[11]:
A
bar 0.253652
baz -2.829711
foo 0.551376
Name: B
in [12]: df['sum_B_over_A'] = df.A.apply(sum_B_over_A.get_value)
In [13]: df
Out[13]:
A B C sum_B_over_A
0 foo 1.624345 False 0.551376
1 bar -0.611756 True 0.253652
2 baz -0.528172 False -2.829711
3 foo -1.072969 True 0.551376
4 bar 0.865408 False 0.253652
5 baz -2.301539 True -2.829711
In [14]: df.sort(['sum_B_over_A', 'A', 'B'])
Out[14]:
A B C sum_B_over_A
5 baz -2.301539 True -2.829711
2 baz -0.528172 False -2.829711
1 bar -0.611756 True 0.253652
4 bar 0.865408 False 0.253652
3 foo -1.072969 True 0.551376
0 foo 1.624345 False 0.551376
and maybe you would drop the dummy row:
In [15]: df.sort(['sum_B_over_A', 'A', 'B']).drop('sum_B_over_A', axis=1)
Out[15]:
A B C
5 baz -2.301539 True
2 baz -0.528172 False
1 bar -0.611756 True
4 bar 0.865408 False

java.util.MissingResourceException: Can't find bundle for base name org.jfree.chart.LocalizationBundle, locale en_US
To the point, the exception message tells in detail that you need to have either of the following files in the classpath:
/org/jfree/chart/LocalizationBundle.properties
or
/org/jfree/chart/LocalizationBundle_en.properties
or
/org/jfree/chart/LocalizationBundle_en_US.properties
Also see the official Java tutorial about resourcebundles for more information.
But as this is actually a 3rd party managed properties file, you shouldn't create one yourself. It should be already available in the JFreeChart JAR file. So ensure that you have it available in the classpath during runtime. Also ensure that you're using the right version, the location of the propertiesfile inside the package tree might have changed per JFreeChart version.
When executing a JAR file, you can use the -cp
argument to specify the classpath. E.g.:
java -jar -cp c:/path/to/jfreechart.jar yourfile.jar
Alternatively you can specify the classpath as class-path
entry in the JAR's manifest file. You can use in there relative paths which are relative to the JAR file itself. Do not use the %CLASSPATH%
environment variable, it's ignored by JAR's and everything else which aren't executed with java.exe
without -cp
, -classpath
and -jar
arguments.
Maybe you have run into this problem: net::ERR_INSECURE_RESPONSE
You need to check the encryption algorithms supported by your server. For example for apache you can configure the cipher suite this way: cipher suite.
Which version of chrome are you running and what is the server serving your APIs?
You can use a simple call in the constructor under "frame initialization":
setResizable(false);
After this call, the window will not be resizable.
Assuming your Generic List is of type String:
TextWriter tw = new StreamWriter("SavedList.txt");
foreach (String s in Lists.verbList)
tw.WriteLine(s);
tw.Close();
Alternatively, with the using keyword:
using(TextWriter tw = new StreamWriter("SavedList.txt"))
{
foreach (String s in Lists.verbList)
tw.WriteLine(s);
}
Sounds like you're working in just one table so something like this:
update your_table

Windows has two different settings in which priority is established. There is the metric value which you have already set in the adapter settings, and then there is the connection priority in the network connections settings.
To change the priority of the connections:
It's the for...in statement
(MDN, ECMAScript spec).
You can read it as "FOR every property IN the obj
object, assign each property to the PROPT variable in turn".
//Multiple selection:

}
}
}
using ==>
clbsec(checkedListBox1,"michael");
or
clbsec(checkedListBox1,textBox1.Text);
or
clbsec(checkedListBox1,dataGridView1.CurrentCell.Value.toString());
Did you use the default installation path?
In my case, when i ran mysql_start.bat I got the following error:
Can`t find messagefile 'D:\xampp\mysql\share\errmsg.sys'
I moved my xampp folder to the root of the drive and it started working.
Hope it helps

Open up terminal and check what java version is currently set in your path variable.
You can do that by typing in your terminal
java -version // this will check your jre version.
javac -version // this will check your compiler version
If this shows incorrect java version but you have installed java 1.8 then you have to set path variable to the newer version of java.
To do that do add the line:
export JAVA_HOME=/path/to/java/jdk1.x
to ~/.bash_profile
(same as /Users/username/.bash_profile
)
Then do this from the terminal to set the new variable
source ~/.bash_profile
Also what's your eclipse.ini set to ?
-Dosgi.requiredJavaVersion=1.7
EDIT:
Please open up terminal and type
find / -name "java" // This should find all folder named java on your file system.
Also how did you install java in the first place ?
You could have the form contain the additional data as hidden fields which you would set right before sending the AJAX request to the corresponding values.
Another possibility consists into using this little gem to serialize your form into a javascript object (instead of string) and add the missing data:
var data = $('#myForm').serializeObject();
// now add some additional stuff
data['wordlist'] = wordlist;
$.post('/page.php', data);
This can happen when you are running IIS
and you run the html page through it, then the Local file system
will not be accessible.
To make your link work locally the run the calling html page directly from file browser not visual studio F5
or IIS
simply click it to open from the file system, and make sure you are using the link like this:
<a href="file:///F:/VS_2015_WorkSpace/Projects/xyz/Intro.html">Intro</a>
You need to set Opacity first for standards-compliant browsers, then the various versions of IE. See Example:
but this opacity code not work in ie8
.slidedownTrigger
{
cursor: pointer;
opacity: .75; /* Standards Compliant Browsers */
filter: alpha(opacity=75); /* IE 7 and Earlier */
/* Next 2 lines IE8 */
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=75)";
filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=75);
}
Note that I eliminated -moz as Firefox is a Standards Compliant browser and that line is no longer necessary. Also, -khtml is depreciated, so I eliminated that style as well.
Furthermore, IE's filters will not validate to w3c standards, so if you want your page to validate, separate your standards stylesheet from your IE stylesheet by using an if IE statement like below:
<!--[if IE]>
<link rel="stylesheet" type="text/css" href="http://www.mysite.com/css/ie.css" />
<![endif]-->
If you separate the ie quirks, your site will validate just fine.
Redux itself is a pretty verbose library, and for such stuff you would have to use something like Redux-thunk, which will give a dispatch
function, so you will be able to dispatch closing of the notification after several seconds.
I have created a library to address issues like verbosity and composability, and your example will look like the following:
import { createTile, createSyncTile } from 'redux-tiles';
import { sleep } from 'delounce';
const notifications = createSyncTile({
type: ['ui', 'notifications'],
fn: ({ params }) => params.data,
// to have only one tile for all notifications
nesting: ({ type }) => [type],
});
const notificationsManager = createTile({
type: ['ui', 'notificationManager'],
fn: ({ params, dispatch, actions }) => {
dispatch(actions.ui.notifications({ type: params.type, data: params.data }));
await sleep(params.timeout || 5000);
dispatch(actions.ui.notifications({ type: params.type, data: null }));
return { closed: true };
},
nesting: ({ type }) => [type],
});
So we compose sync actions for showing notifications inside async action, which can request some info the background, or check later whether the notification was closed manually.
to make it simple, just add a class="form-inline"
before the input.
example:
<div class="col-md-4 form-inline"> //add the class here...
<label>Lot Size:</label>
<input type="text" value="" name="" class="form-control" >
</div>
In Python a callable is an object which type has a __call__
method:
>>> class Foo:
... pass
...
>>> class Bar(object):
... pass
...
>>> type(Foo).__call__(Foo)
<__main__.Foo instance at 0x711440>
>>> type(Bar).__call__(Bar)
<__main__.Bar object at 0x712110>
>>> def foo(bar):
... return bar
...
>>> type(foo).__call__(foo, 42)
42
As simple as that :)
This of course can be overloaded:
>>> class Foo(object):
... def __call__(self):
... return 42
...
>>> f = Foo()
>>> f()
42
Try this
sudo -u hdfs hdfs dfsadmin -safemode leave
check status of safemode
sudo -u hdfs hdfs dfsadmin -safemode get
If it is still in safemode ,then one of the reason would be not enough space in your node, you can check your node disk usage using :
df -h
if root partition is full, delete files or add space in your root partition and retry first step.
that’s just wrong: is not a wrapper. The element denotes a semantic section of your content to help construct a document outline. It should contain a heading. If you’re looking for a page wrapper element (for any flavour of HTML or XHTML), consider applying styles directly to the element as described by Kroc Camen. If you still need an additional element for styling, use a . As Dr Mike explains, div isn’t dead, and if there’s nothing else more appropriate, it’s probably where you really want to apply your CSS.

Just adding a bit of extra information here in case someone has the same issue as me.
I use namespaces in my code and I had a class with a function that throws an Exception.
However my try/catch code in another class file was completely ignored and the normal PHP error for an uncatched exception was thrown.
Turned out I forgot to add "use \Exception;" at the top, adding that solved the error.
Everyone will have slightly different definitions, and there are often grey areas. However:
On Debian (isn't this the case for most Linux distros?), it's saved in /var/lib/php5/. As mentioned above, it's configured in your php.ini.
Try:
$data = file_get_contents ("file.json");
$json = json_decode($data, true);
foreach ($json as $key => $value) {
if (!is_array($value)) {
echo $key . '=>' . $value . '<br/>';
} else {
foreach ($value as $key => $val) {
echo $key . '=>' . $val . '<br/>';
}
}
}
The or
operator returns the first operand if it is true, otherwise the second operand. So in your case your test is equivalent to if name == "Jesse"
.
The correct application of or
would be:
if (name == "Jesse") or (name == "jesse"):
Well, for one thing your epression can be simplified:
$("#pDetails").attr("style")
since there should only be one element for any given ID and the ID selector will be much faster than the attribute id selector you're using.
If you just want to return the display value or something, use css():
$("#pDetails").css("display")
If you want to search for elements that have display none, that's a lot harder to do reliably. This is a rough example that won't be 100%:
$("[style*='display: none']")
but if you just want to find things that are hidden, use this:
$(":hidden")
@Bobince is providing a really opaque answer.
Riffing off of Már Örlygsson's answer, Javascript is always single-threaded because of this simple fact: Everything in Javascript is executed along a single timeline.
That is the strict definition of a single-threaded programming language.
I used Oracle SQL developer to export the table/s into CSV format and then did the comparison using WinMerge.
Object Oriented Programming offers:
Functional Programming, in Haskell or even in Scala, can allow substitution through more general mechanism of type classes. Mutable internal state is either discouraged or forbidden. Encapsulation of internal representation can also be achieved. See Haskell vs OOP for a good comparison.
Norman's assertion that "Adding a new kind of thing to a functional program may require editing many function definitions to add a new case." depends on how well the functional code has employed type classes. If Pattern Matching on a particular Abstract Data Type is spread throughout a codebase, you will indeed suffer from this problem, but it is perhaps a poor design to start with.
EDITED Removed reference to implicit conversions when discussing type classes. In Scala, type classes are encoded with implicit parameters, not conversions, although implicit conversions are another means to acheiving substitution of compatible types.
Ok,
I managed to solve this tricky issue. The thing was like I was using FrameLayout
. Don't know why but it came to my mind that may be the icon would be getting hidden behind some other view.
I tried putting the icon at the end of my layout and now I am able to see the Toast
as well as the Log
.
Thank you everybody for taking time to solve the issue.. Was surely tricky..
the easiest way in python 3.x
text = "hi , I'm text"
text.encode('utf-8')
Httponly cookies' purpose is being inaccessible by script, so you CAN NOT.
For HTML Entities
◄ = ◄
► = ►
▼ = ▼
▲ = ▲
So that its value can easily contain quotes and <> characters and respect whitespace and newlines.
The following HTML code successfully pass the w3c validator and displays <,> and & without the need to encode them. It also respects the white spaces.
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Yes I can</title>
</head>
<body>
<textarea name="test">
I can put < and > and & signs in
my textarea without any problems.
</textarea>
</body>
</html>
Simply last
would work here:
for my $entry (@array){
if ($string eq "text"){
last;
}
}
If you have nested loops, then last
will exit from the innermost loop. Use labels in this case:
LBL_SCORE: {
for my $entry1 (@array1) {
for my $entry2 (@array2) {
if ($entry1 eq $entry2) { # Or any condition
last LBL_SCORE;
}
}
}
}
Given a last
statement will make the compiler to come out from both the loops. The same can be done in any number of loops, and labels can be fixed anywhere.
# s1 == source string
# char == find this character
# repl == replace with this character
def findreplace(s1, char, repl):
s1 = s1.replace(char, repl)
return s1
# find each 'i' in the string and replace with a 'u'
print findreplace('it is icy', 'i', 'u')
# output
''' ut us ucy '''
You're storing the .Text
properties of the textboxes directly into the database, this doesn't work. The .Text
properties are String
s (i.e. simple text) and not typed as DateTime
instances. Do the conversion first, then it will work.
Do this for each date parameter:
Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) )
Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse
or DateTime.TryParseExact
, but implementing that is an exercise for the reader.
You will have to put:
X = input("give starting number")
X = int(X)
Y = input("give ending number")
Y = int(Y)
Use H
or HH
instead of hh
. See http://momentjs.com/docs/#/parsing/string-format/
I had the same issue and the following has fixed it (using node 12.13.1):
more info: https://nodejs.org/api/esm.html
In SQL Server you can use YEAR
, MONTH
and DAY
instead of DATEPART
.
(at least in SQL Server 2005/2008, I'm not sure about SQL Server 2000 and older)
I prefer using these "short forms" because to me, YEAR(getdate())
is shorter to type and better to read than DATEPART(yyyy, getdate())
.
So you could also query your table like this:
select *
from your_table
where month_column = MONTH(getdate())
and year_column = YEAR(getdate())
No they can't. But:
template<typename T>
class Foo {
public:
template<typename P>
void f(const P& p) {
((T*)this)->f<P>(p);
}
};
class Bar : public Foo<Bar> {
public:
template<typename P>
void f(const P& p) {
std::cout << p << std::endl;
}
};
int main() {
Bar bar;
Bar *pbar = &bar;
pbar -> f(1);
Foo<Bar> *pfoo = &bar;
pfoo -> f(1);
};
has much the same effect if all you want to do is have a common interface and defer implementation to subclasses.
If you are using AsyncTask
, probably that log message can be deceptive. If you look up in your log, you might find another error, probably one in your doInBackground()
method of your AsyncTask
, that is making your current Activity
to blow up, and thus once the AsyncTask
comes back.. well, you know the rest. Some other users already explained that here :-)
Here is an example of decoding a generic map using both switch and reflection, so if you don't match the type, use reflection to figure it out and then add the type in next time.
var data map[string]interface {}
...
for k, v := range data {
fmt.Printf("pair:%s\t%s\n", k, v)
switch t := v.(type) {
case int:
fmt.Printf("Integer: %v\n", t)
case float64:
fmt.Printf("Float64: %v\n", t)
case string:
fmt.Printf("String: %v\n", t)
case bool:
fmt.Printf("Bool: %v\n", t)
case []interface {}:
for i,n := range t {
fmt.Printf("Item: %v= %v\n", i, n)
}
default:
var r = reflect.TypeOf(t)
fmt.Printf("Other:%v\n", r)
}
}
Does React re-render all components and sub-components every time setState is called?
By default - yes.
There is a method boolean shouldComponentUpdate(object nextProps, object nextState), each component has this method and it's responsible to determine "should component update (run render function)?" every time you change state or pass new props from parent component.
You can write your own implementation of shouldComponentUpdate method for your component, but default implementation always returns true - meaning always re-run render function.
Quote from official docs http://facebook.github.io/react/docs/component-specs.html#updating-shouldcomponentupdate
By default, shouldComponentUpdate always returns true to prevent subtle bugs when the state is mutated in place, but if you are careful to always treat the state as immutable and to read-only from props and state in render() then you can override shouldComponentUpdate with an implementation that compares the old props and state to their replacements.
Next part of your question:
If so, why? I thought the idea was that React only rendered as little as needed - when the state changed.
There are two steps of what we may call "render":
Virtual DOM renders: when render method is called it returns a new virtual dom structure of the component. As I mentioned before, this render method is called always when you call setState(), because shouldComponentUpdate always returns true by default. So, by default, there is no optimization here in React.
Native DOM renders: React changes real DOM nodes in your browser only if they were changed in the Virtual DOM and as little as needed - this is that great React's feature which optimizes real DOM mutation and makes React fast.
Edit: Here's a plugin I authored that extends the jQuery UI Dialog to include closing when clicking outside plus other features: https://github.com/jasonday/jQuery-UI-Dialog-extended
Here are 3 methods to close a jquery UI dialog when clicking outside popin:
If the dialog is modal/has background overlay: http://jsfiddle.net/jasonday/6FGqN/
jQuery(document).ready(function() {
jQuery("#dialog").dialog({
bgiframe: true,
autoOpen: false,
height: 100,
modal: true,
open: function() {
jQuery('.ui-widget-overlay').bind('click', function() {
jQuery('#dialog').dialog('close');
})
}
});
});
If dialog is non-modal Method 1: http://jsfiddle.net/jasonday/xpkFf/
// Close Pop-in If the user clicks anywhere else on the page
jQuery('body')
.bind('click', function(e) {
if(jQuery('#dialog').dialog('isOpen')
&& !jQuery(e.target).is('.ui-dialog, a')
&& !jQuery(e.target).closest('.ui-dialog').length
) {
jQuery('#dialog').dialog('close');
}
});
Non-Modal dialog Method 2: http://jsfiddle.net/jasonday/eccKr/
$(function() {
$('#dialog').dialog({
autoOpen: false,
minHeight: 100,
width: 342,
draggable: true,
resizable: false,
modal: false,
closeText: 'Close',
open: function() {
closedialog = 1;
$(document).bind('click', overlayclickclose); },
focus: function() {
closedialog = 0; },
close: function() {
$(document).unbind('click'); }
});
$('#linkID').click(function() {
$('#dialog').dialog('open');
closedialog = 0;
});
var closedialog;
function overlayclickclose() {
if (closedialog) {
$('#dialog').dialog('close');
}
//set to one because click on dialog box sets to zero
closedialog = 1;
}
});
I had to add a footer to my RecyclerView
and here I'm sharing my code snippet as I thought it might be useful. Please check the comments inside the code for better understanding of the overall flow.
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import java.util.ArrayList;
public class RecyclerViewWithFooterAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private static final int FOOTER_VIEW = 1;
private ArrayList<String> data; // Take any list that matches your requirement.
private Context context;
// Define a constructor
public RecyclerViewWithFooterAdapter(Context context, ArrayList<String> data) {
this.context = context;
this.data = data;
}
// Define a ViewHolder for Footer view
public class FooterViewHolder extends ViewHolder {
public FooterViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Do whatever you want on clicking the item
}
});
}
}
// Now define the ViewHolder for Normal list item
public class NormalViewHolder extends ViewHolder {
public NormalViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Do whatever you want on clicking the normal items
}
});
}
}
// And now in onCreateViewHolder you have to pass the correct view
// while populating the list item.
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v;
if (viewType == FOOTER_VIEW) {
v = LayoutInflater.from(context).inflate(R.layout.list_item_footer, parent, false);
FooterViewHolder vh = new FooterViewHolder(v);
return vh;
}
v = LayoutInflater.from(context).inflate(R.layout.list_item_normal, parent, false);
NormalViewHolder vh = new NormalViewHolder(v);
return vh;
}
// Now bind the ViewHolder in onBindViewHolder
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
try {
if (holder instanceof NormalViewHolder) {
NormalViewHolder vh = (NormalViewHolder) holder;
vh.bindView(position);
} else if (holder instanceof FooterViewHolder) {
FooterViewHolder vh = (FooterViewHolder) holder;
}
} catch (Exception e) {
e.printStackTrace();
}
}
// Now the critical part. You have return the exact item count of your list
// I've only one footer. So I returned data.size() + 1
// If you've multiple headers and footers, you've to return total count
// like, headers.size() + data.size() + footers.size()
@Override
public int getItemCount() {
if (data == null) {
return 0;
}
if (data.size() == 0) {
//Return 1 here to show nothing
return 1;
}
// Add extra view to show the footer view
return data.size() + 1;
}
// Now define getItemViewType of your own.
@Override
public int getItemViewType(int position) {
if (position == data.size()) {
// This is where we'll add footer.
return FOOTER_VIEW;
}
return super.getItemViewType(position);
}
// So you're done with adding a footer and its action on onClick.
// Now set the default ViewHolder for NormalViewHolder
public class ViewHolder extends RecyclerView.ViewHolder {
// Define elements of a row here
public ViewHolder(View itemView) {
super(itemView);
// Find view by ID and initialize here
}
public void bindView(int position) {
// bindView() method to implement actions
}
}
}
The above code snippet adds a footer to the RecyclerView
. You can check this GitHub repository for checking the implementation of adding both header and a footer.
You could try this:
$in_str = 'this is a test';
$hex_ary = array();
foreach (str_split($in_str) as $chr) {
$hex_ary[] = sprintf("%02X", ord($chr));
}
echo implode(' ',$hex_ary);
