The first link in Google for 'matplotlib figure size'
is AdjustingImageSize (Google cache of the page).
Here's a test script from the above page. It creates test[1-3].png
files of different sizes of the same image:
#!/usr/bin/env python
"""
This is a small demo file that helps teach how to adjust figure sizes
for matplotlib
"""
import matplotlib
print "using MPL version:", matplotlib.__version__
matplotlib.use("WXAgg") # do this before pylab so you don'tget the default back end.
import pylab
import numpy as np
# Generate and plot some simple data:
x = np.arange(0, 2*np.pi, 0.1)
y = np.sin(x)
pylab.plot(x,y)
F = pylab.gcf()
# Now check everything with the defaults:
DPI = F.get_dpi()
print "DPI:", DPI
DefaultSize = F.get_size_inches()
print "Default size in Inches", DefaultSize
print "Which should result in a %i x %i Image"%(DPI*DefaultSize[0], DPI*DefaultSize[1])
# the default is 100dpi for savefig:
F.savefig("test1.png")
# this gives me a 797 x 566 pixel image, which is about 100 DPI
# Now make the image twice as big, while keeping the fonts and all the
# same size
F.set_size_inches( (DefaultSize[0]*2, DefaultSize[1]*2) )
Size = F.get_size_inches()
print "Size in Inches", Size
F.savefig("test2.png")
# this results in a 1595x1132 image
# Now make the image twice as big, making all the fonts and lines
# bigger too.
F.set_size_inches( DefaultSize )# resetthe size
Size = F.get_size_inches()
print "Size in Inches", Size
F.savefig("test3.png", dpi = (200)) # change the dpi
# this also results in a 1595x1132 image, but the fonts are larger.
Output:
using MPL version: 0.98.1
DPI: 80
Default size in Inches [ 8. 6.]
Which should result in a 640 x 480 Image
Size in Inches [ 16. 12.]
Size in Inches [ 16. 12.]
Two notes:
The module comments and the actual output differ.
This answer allows easily to combine all three images in one image file to see the difference in sizes.
Dummy data (you should supply this for us)
visual1 = data.frame(ISSUE_DATE=runif(100,2006,2008),COUNTED=runif(100,0,50))
visual2 = data.frame(ISSUE_DATE=runif(100,2006,2008),COUNTED=runif(100,0,50))
combine:
visuals = rbind(visual1,visual2)
visuals$vis=c(rep("visual1",100),rep("visual2",100)) # 100 points of each flavour
Now do:
ggplot(visuals, aes(ISSUE_DATE,COUNTED,group=vis,col=vis)) +
geom_point() + geom_smooth()
and adjust colours etc to taste.
You also can use Gnuplot
which is also available from gretl
. Put your x y z data on a text file an insert the following
splot 'test.txt' using 1:2:3 with points palette pointsize 3 pointtype 7
Then you can set labels, etc. using
set xlabel "xxx" rotate parallel
set ylabel "yyy" rotate parallel
set zlabel "zzz" rotate parallel
set grid
show grid
unset key
This is an old question but none of the previous answers has addressed the real issue, i.e. that fact that the problem is with the question itself.
First, if the probabilities have been already calculated, i.e. the histogram aggregated data is available in a normalized way then the probabilities should add up to 1. They obviously do not and that means that something is wrong here, either with terminology or with the data or in the way the question is asked.
Second, the fact that the labels are provided (and not intervals) would normally mean that the probabilities are of categorical response variable - and a use of a bar plot for plotting the histogram is best (or some hacking of the pyplot's hist method), Shayan Shafiq's answer provides the code.
However, see issue 1, those probabilities are not correct and using bar plot in this case as "histogram" would be wrong because it does not tell the story of univariate distribution, for some reason (perhaps the classes are overlapping and observations are counted multiple times?) and such plot should not be called a histogram in this case.
Histogram is by definition a graphical representation of the distribution of univariate variable (see Histogram | NIST/SEMATECH e-Handbook of Statistical Methods & Histogram | Wikipedia) and is created by drawing bars of sizes representing counts or frequencies of observations in selected classes of the variable of interest. If the variable is measured on a continuous scale those classes are bins (intervals). Important part of histogram creation procedure is making a choice of how to group (or keep without grouping) the categories of responses for a categorical variable, or how to split the domain of possible values into intervals (where to put the bin boundaries) for continuous type variable. All observations should be represented, and each one only once in the plot. That means that the sum of the bar sizes should be equal to the total count of observation (or their areas in case of the variable widths, which is a less common approach). Or, if the histogram is normalised then all probabilities must add up to 1.
If the data itself is a list of "probabilities" as a response, i.e. the observations are probability values (of something) for each object of study then the best answer is simply plt.hist(probability)
with maybe binning option, and use of x-labels already available is suspicious.
Then bar plot should not be used as histogram but rather simply
import matplotlib.pyplot as plt
probability = [0.3602150537634409, 0.42028985507246375,
0.373117033603708, 0.36813186813186816, 0.32517482517482516,
0.4175257731958763, 0.41025641025641024, 0.39408866995073893,
0.4143222506393862, 0.34, 0.391025641025641, 0.3130841121495327,
0.35398230088495575]
plt.hist(probability)
plt.show()
with the results
matplotlib in such case arrives by default with the following histogram values
(array([1., 1., 1., 1., 1., 2., 0., 2., 0., 4.]),
array([0.31308411, 0.32380469, 0.33452526, 0.34524584, 0.35596641,
0.36668698, 0.37740756, 0.38812813, 0.39884871, 0.40956928,
0.42028986]),
<a list of 10 Patch objects>)
the result is a tuple of arrays, the first array contains observation counts, i.e. what will be shown against the y-axis of the plot (they add up to 13, total number of observations) and the second array are the interval boundaries for x-axis.
One can check they they are equally spaced,
x = plt.hist(probability)[1]
for left, right in zip(x[:-1], x[1:]):
print(left, right, right-left)
Or, for example for 3 bins (my judgment call for 13 observations) one would get this histogram
plt.hist(probability, bins=3)
with the plot data "behind the bars" being
The author of the question needs to clarify what is the meaning of the "probability" list of values - is the "probability" just a name of the response variable (then why are there x-labels ready for the histogram, it makes no sense), or are the list values the probabilities calculated from the data (then the fact they do not add up to 1 makes no sense).
You can convert the categorical column into a numerical one by using the commands:
#we converting it into categorical data
cat_col = df['column_name'].astype('categorical')
#we are getting codes for it
cat_col = cat_col.cat.codes
# we are using c parameter to change the color.
plt.scatter(df['column1'],df['column2'], c=cat_col)
The above solutions may not be efficient if you want to plot multiple ggplot plots using a loop (e.g. as asked here: Creating multiple plots in ggplot with different Y-axis values using a loop), which is a desired step in analyzing the unknown (or large) data-sets (e.g., when you want to plot Counts of all variables in a data-set).
The code below shows how to do that using the mentioned above 'multiplot()', the source of which is here: http://www.cookbook-r.com/Graphs/Multiple_graphs_on_one_page_(ggplot2):
plotAllCounts <- function (dt){
plots <- list();
for(i in 1:ncol(dt)) {
strX = names(dt)[i]
print(sprintf("%i: strX = %s", i, strX))
plots[[i]] <- ggplot(dt) + xlab(strX) +
geom_point(aes_string(strX),stat="count")
}
columnsToPlot <- floor(sqrt(ncol(dt)))
multiplot(plotlist = plots, cols = columnsToPlot)
}
Now run the function - to get Counts for all variables printed using ggplot on one page
dt = ggplot2::diamonds
plotAllCounts(dt)
One things to note is that:
using aes(get(strX))
, which you would normally use in loops when working with ggplot
, in the above code instead of aes_string(strX)
will NOT draw the desired plots. Instead, it will plot the last plot many times. I have not figured out why - it may have to do the aes
and aes_string
are called in ggplot
.
Otherwise, hope you'll find the function useful.
I'm start to create own Perl script based on SQL::Translator module (GraphViz). Here are first results.
Just a supplement here.
The following question is that what if I want more subplots in the figure?
As mentioned in the Doc, we can use fig = plt.subplots(nrows=2, ncols=2)
to set a group of subplots with grid(2,2) in one figure object.
Then as we know, the fig, ax = plt.subplots()
returns a tuple, let's try fig, ax1, ax2, ax3, ax4 = plt.subplots(nrows=2, ncols=2)
firstly.
ValueError: not enough values to unpack (expected 4, got 2)
It raises a error, but no worry, because we now see that plt.subplots()
actually returns a tuple with two elements. The 1st one must be a figure object, and the other one should be a group of subplots objects.
So let's try this again:
fig, [[ax1, ax2], [ax3, ax4]] = plt.subplots(nrows=2, ncols=2)
and check the type:
type(fig) #<class 'matplotlib.figure.Figure'>
type(ax1) #<class 'matplotlib.axes._subplots.AxesSubplot'>
Of course, if you use parameters as (nrows=1, ncols=4), then the format should be:
fig, [ax1, ax2, ax3, ax4] = plt.subplots(nrows=1, ncols=4)
So just remember to keep the construction of the list as the same as the subplots grid we set in the figure.
Hope this would be helpful for you.
You could use 'corrplot' package.
d <- data.frame(x1=rnorm(10),
x2=rnorm(10),
x3=rnorm(10))
M <- cor(d) # get correlations
library('corrplot') #package corrplot
corrplot(M, method = "circle") #plot matrix

If, like me, you have a problem installing graphviz, you can visualize the tree by
export_graphviz
as shown in previous answers.dot
file in a text editorThere is a wonderful print_r
implementation for JavaScript in php.js library.
Note, you should also add echo
support in the code.
You can use the foreach for an simple array like
int[] test = { 0, 1, 2, 3, ...};
And you can use the for when you have a 2D array
int[][] test = {{1,2,3,4},
{5,2,6,5,8}};
Nobody mentioned using reversed:
f=open(file,"r")
r=reversed(f.readlines())
last_line_of_file = r.next()
Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import
to Tkinter
rather than tkinter
(the difference being the capitalization):
import tkinter as tk
#import Tkinter as tk # for python 2
def create_window():
window = tk.Toplevel(root)
root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()
root.mainloop()
This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.
from pathlib import Path
data_folder = Path("source_data/text_files/")
file_to_open = data_folder / "raw_data.txt"

Version 1:
// Update data of question values with $data from formulay
$Q1 = Question::find($id);
$Q1->fill($data);
$Q1->push();
Version 2:
$Q1 = Question::find($id);
$Q1->field = 'YOUR TEXT OR VALUE';
$Q1->save();
In case of answered question you can use them:
$page = Page::find($id);
$page2update = $page->where('image', $path);
$page2update->image = 'IMGVALUE';
$page2update->save();
You can use the event ProgressChanged ; the last time it is raised will indicate that the document is fully rendered:
this.webBrowser.ProgressChanged += new
WebBrowserProgressChangedEventHandler(webBrowser_ProgressChanged);
svn merge -r 1944:1943 .
should revert the changes of r1944 in your working copy. You can then review the changes in your working copy (with diff), but you'd need to commit in order to apply the revert into the repository.
See sys.exit
. That function will quit your program with the given exit status.
The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.
If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.
Imo, you should try MySQL Connector/Node.js which is the official Node.js driver for MySQL. See ref-1 and ref-2 for detailed explanation. I have tried mysqljs/mysql which is available here, but I don't find detailed documentation on classes, methods, properties of this library.
So I switched to the standard MySQL Connector/Node.js
with X DevAPI
, since it is an asynchronous Promise-based client library and provides good documentation.
Take a look at the following code snippet :
const mysqlx = require('@mysql/xdevapi');
const rows = [];
mysqlx.getSession('mysqlx://localhost:33060')
.then(session => {
const table = session.getSchema('testSchema').getTable('testTable');
// The criteria is defined through the expression.
return table.update().where('name = "bar"').set('age', 50)
.execute()
.then(() => {
return table.select().orderBy('name ASC')
.execute(row => rows.push(row));
});
})
.then(() => {
console.log(rows);
});
var elementCheckBox = document.getElementById("IdOfCheckBox");_x000D_
_x000D_
_x000D_
elementCheckBox[0].checked //return true if checked and false if not checked
_x000D_

Use the wait
built-in:
process1 &
process2 &
process3 &
process4 &
wait
process5 &
process6 &
process7 &
process8 &
wait
For the above example, 4 processes process1
... process4
would be started in the background, and the shell would wait until those are completed before starting the next set.
From the GNU manual:
wait [jobspec or pid ...]
Wait until the child process specified by each process ID pid or job specification jobspec exits and return the exit status of the last command waited for. If a job spec is given, all processes in the job are waited for. If no arguments are given, all currently active child processes are waited for, and the return status is zero. If neither jobspec nor pid specifies an active child process of the shell, the return status is 127.

You could use pandas for that (although it could be overhead for that task). You could use round, floor and ceil like for usual numbers and any pandas frequency from offset-aliases:
import pandas as pd
import datetime as dt
now = dt.datetime.now()
pd_now = pd.Timestamp(now)
freq = '1d'
pd_round = pd_now.round(freq)
dt_round = pd_round.to_pydatetime()
print(now)
print(dt_round)

If there are no typos in the question, you got the conditions wrong:
You said this:
IF cells (i,"A") contains the text 'Miami'
...but your code says:
If Cells(i, "A") <> "Miami"
--> <>
means that the value of the cell is not equal to "Miami", so you're not checking what you think you are checking.
I guess you want this instead:
If Cells(i, "A") like "*Miami*"
EDIT:
Sorry, but I can't really help you more. As I already said in a comment, I'm no Excel VBA expert.
Normally I would open Excel now and try your code myself, but I don't even have Excel on any of my machines at home (I use OpenOffice).
Just one general thing: can you identify the row that does not work?
Maybe this helps someone else to answer the question.
Does it ever execute (or at least try to execute) the Cells(i, "C").Value = "BA"
line?
Or is the If Cells(i, "A") like "*Miami*"
stuff already False
?
If yes, try checking just one cell and see if that works.
You can get the PID of a particular process like MySQL by using following commands: ps -e | pgrep mysql
This command will give you the PID of MySQL rocess. e.g, 13954 Now, type following command on terminal. kill -9 13954 This will kill the process of MySQL.

Its not possible to access any PHP function inside Twig directly.
What you can do is write a Twig extension. A common structure is, writing a service with some utility functions, write a Twig extension as bridge to access the service from twig. The Twig extension will use the service and your controller can use the service too.
Take a look: http://symfony.com/doc/current/cookbook/templating/twig_extension.html

In some cases you may not be able to directly upload entire folder containing folders, In such cases, you will have to create directory structure yourself.

One more major difference between fetch API & axios API
You can do inline ifs with

According to eduLINQ:
The best way to get to grips with what GroupJoin does is to think of Join. There, the overall idea was that we looked through the "outer" input sequence, found all the matching items from the "inner" sequence (based on a key projection on each sequence) and then yielded pairs of matching elements. GroupJoin is similar, except that instead of yielding pairs of elements, it yields a single result for each "outer" item based on that item and the sequence of matching "inner" items.
The only difference is in return statement:
Join:
var lookup = inner.ToLookup(innerKeySelector, comparer);
foreach (var outerElement in outer)
{
var key = outerKeySelector(outerElement);
foreach (var innerElement in lookup[key])
{
yield return resultSelector(outerElement, innerElement);
}
}
GroupJoin:
var lookup = inner.ToLookup(innerKeySelector, comparer);
foreach (var outerElement in outer)
{
var key = outerKeySelector(outerElement);
yield return resultSelector(outerElement, lookup[key]);
}

Minimal example varying azim
, dist
and elev
To add some simple sample images to what was explained at: https://stackoverflow.com/a/12905458/895245
Here is my test program:
#!/usr/bin/env python3
import sys
import matplotlib.pyplot as plt
from matplotlib import cm
from matplotlib.ticker import LinearLocator, FormatStrFormatter
import numpy as np
fig = plt.figure()
ax = fig.gca(projection='3d')
if len(sys.argv) > 1:
azim = int(sys.argv[1])
else:
azim = None
if len(sys.argv) > 2:
dist = int(sys.argv[2])
else:
dist = None
if len(sys.argv) > 3:
elev = int(sys.argv[3])
else:
elev = None
# Make data.
X = np.arange(-5, 6, 1)
Y = np.arange(-5, 6, 1)
X, Y = np.meshgrid(X, Y)
Z = X**2
# Plot the surface.
surf = ax.plot_surface(X, Y, Z, linewidth=0, antialiased=False)
# Labels.
ax.set_xlabel('x')
ax.set_ylabel('y')
ax.set_zlabel('z')
if azim is not None:
ax.azim = azim
if dist is not None:
ax.dist = dist
if elev is not None:
ax.elev = elev
print('ax.azim = {}'.format(ax.azim))
print('ax.dist = {}'.format(ax.dist))
print('ax.elev = {}'.format(ax.elev))
plt.savefig(
'main_{}_{}_{}.png'.format(ax.azim, ax.dist, ax.elev),
format='png',
bbox_inches='tight'
)
Running it without arguments gives the default values:
ax.azim = -60
ax.dist = 10
ax.elev = 30
main_-60_10_30.png
Vary azim
The azimuth is the rotation around the z axis e.g.:
main_-60_10_30.png
main_0_10_30.png
main_60_10_30.png
Vary dist
dist
seems to be the distance from the center visible point in data coordinates.
main_-60_10_30.png
main_-60_5_30.png
main_-60_20_-30.png
Vary elev
From this we understand that elev

sys.argv[1] contains the first command line argument passed to your script.
For example, if your script is named hello.py
and you issue:
$ python3.1 hello.py foo
or:
$ chmod +x hello.py # make script executable
$ ./hello.py foo
Your script will print:
Hello there foo
nvarchar(max)
field move that field to the bottom of your table.There are 3 scenarios for using a class helper like SimpleDateFormat in multithread code, which best one is use ThreadLocal
Scenarios
1- Using like share object by the help of lock or synchronization mechanism which makes the app slow
2- Using as a local object inside a method
In this scenario, if we have 4 thread each one calls a method 1000 time then we have
4000 SimpleDateFormat object created and waiting for GC to erase them
3- Using ThreadLocal
if we have 4 thread and we gave to each thread one SimpleDateFormat instance
so we have 4 threads, 4 objects of SimpleDateFormat.
There is no need of lock mechanism and object creation and destruction. (Good time complexity and space complexity)
You can get the Class reference of any class during run time through the Java Reflection Concept.
Check the Below Code. Explanation is given below
Here is one example that uses returned Class to create an instance of AClass:
package com.xyzws;
class AClass {
public AClass() {
System.out.println("AClass's Constructor");
}
static {
System.out.println("static block in AClass");
}
}
public class Program {
public static void main(String[] args) {
try {
System.out.println("The first time calls forName:");
Class c = Class.forName("com.xyzws.AClass");
AClass a = (AClass)c.newInstance();
System.out.println("The second time calls forName:");
Class c1 = Class.forName("com.xyzws.AClass");
} catch (ClassNotFoundException e) {
// ...
} catch (InstantiationException e) {
// ...
} catch (IllegalAccessException e) {
// ...
}
}
}
The printed output is
The first time calls forName:
static block in AClass
AClass's Constructor
The second time calls forName:
The class has already been loaded so there is no second "static block in AClass"
The Explanation is below
Class.ForName is called to get a Class Object
By Using the Class Object we are creating the new instance of the Class.
Any doubts about this let me know
Add relative positioning to the wrapping div tag, then absolutely position the image within it like this:
CSS:
.div-wrapper {
position: relative;
height: 300px;
width: 300px;
}
.div-wrapper img {
position: absolute;
left: 0;
bottom: 0;
}
HTML:
<div class="div-wrapper">
<img src="blah.png"/>
</div>
Now the image sits at the bottom of the div.
Just add this below JS file
<script type="text/javascript">
$(document).ready(function () {
$('your input's id or class with # or .').datepicker({
format: "dd/mm/yyyy"
});
});
</script>
You're missing comma (,
) inbetween:
>>> ((1,2) (2,3))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'tuple' object is not callable
Put comma:
>>> ((1,2), (2,3))
((1, 2), (2, 3))
URL-encoded payload must be provided on the body
parameter of the http.NewRequest(method, urlStr string, body io.Reader)
method, as a type that implements io.Reader
interface.
Based on the sample code:
package main
import (
"fmt"
"net/http"
"net/url"
"strconv"
"strings"
)
func main() {
apiUrl := "https://api.com"
resource := "/user/"
data := url.Values{}
data.Set("name", "foo")
data.Set("surname", "bar")
u, _ := url.ParseRequestURI(apiUrl)
u.Path = resource
urlStr := u.String() // "https://api.com/user/"
client := &http.Client{}
r, _ := http.NewRequest(http.MethodPost, urlStr, strings.NewReader(data.Encode())) // URL-encoded payload
r.Header.Add("Authorization", "auth_token=\"XXXXXXX\"")
r.Header.Add("Content-Type", "application/x-www-form-urlencoded")
r.Header.Add("Content-Length", strconv.Itoa(len(data.Encode())))
resp, _ := client.Do(r)
fmt.Println(resp.Status)
}
resp.Status
is 200 OK
this way.
oh boy, this got resolved, I just had to name my Installed JRE appropriately. I had only the jdk installed and eclipse had taken the default jdk name, i renamed it to JavaSE-1.6 and voila it worked, though i had to redo everthing from the scratch.
You can do it in one line like this
string[0].toUpperCase() + string.substring(1)
This seemed easier to think about where either of two parameters could be passed into a stored procedure. It seems to work:
SELECT *
FROM x
WHERE CONDITION1
AND ((@pol IS NOT NULL AND x.PolicyNo = @pol) OR (@st IS NOT NULL AND x.State = @st))
AND OTHERCONDITIONS
EDIT: Below was the preferred solution in 2014. Nowadays you should use @include
, as mentioned in the other answer.
In Laravel views the dot is used as folder separator. So for example I have this code
return View::make('auth.details', array('id' => $id));
which points to app/views/auth/details.blade.php
And to include a view inside a view you do like this:
file: layout.blade.php
<html>
<html stuff>
@yield('content')
</html>
file: hello.blade.php
@extends('layout')
@section('content')
<html stuff>
@stop
You can set min-width property of CSS for body tag. Since this property is not supported by IE6, you can write like:
body{
min-width:1000px; /* Suppose you want minimum width of 1000px */
width: auto !important; /* Firefox will set width as auto */
width:1000px; /* As IE6 ignores !important it will set width as 1000px; */
}
Or:
body{
min-width:1000px; // Suppose you want minimum width of 1000px
_width: expression( document.body.clientWidth > 1000 ? "1000px" : "auto" ); /* sets max-width for IE6 */
}
With the example class you posted it doesn't seem to make much sense to test getFuel()
and getSpeed()
since they can only return 0 (there are no setters).
However, assuming that this was just a simplified example for illustrative purposes, and that you have legitimate reasons to test methods in the abstract base class (others have already pointed out the implications), you could setup your test code so that it creates an anonymous subclass of the base class that just provides dummy (no-op) implementations for the abstract methods.
For example, in your TestCase
you could do this:
c = new Car() {
void drive() { };
};
Then test the rest of the methods, e.g.:
public class CarTest extends TestCase
{
private Car c;
public void setUp()
{
c = new Car() {
void drive() { };
};
}
public void testGetFuel()
{
assertEquals(c.getFuel(), 0);
}
[...]
}
(This example is based on JUnit3 syntax. For JUnit4, the code would be slightly different, but the idea is the same.)
cd my_directory/ && tar -zcvf ../my_dir.tgz . && cd -
should do the job in one line. It works well for hidden files as well. "*" doesn't expand hidden files by path name expansion at least in bash. Below is my experiment:
$ mkdir my_directory
$ touch my_directory/file1
$ touch my_directory/file2
$ touch my_directory/.hiddenfile1
$ touch my_directory/.hiddenfile2
$ cd my_directory/ && tar -zcvf ../my_dir.tgz . && cd ..
./
./file1
./file2
./.hiddenfile1
./.hiddenfile2
$ tar ztf my_dir.tgz
./
./file1
./file2
./.hiddenfile1
./.hiddenfile2
Your looking for the onSelect event in the datepicker object:
$('.selector').datepicker({
onSelect: function(dateText, inst) { ... }
});
var page_url = windws.location.href;
var page_id = page_url.substring(page_url.lastIndexOf("#") + 1);
if (page_id == "") {
$("html, body").animate({
scrollTop: $("#scroll-" + page_id).offset().top
}, 2000)
} else if (page_id == "") {
$("html, body").animate({
scrollTop: $("#scroll-" + page_id).offset().top
}, 2000)
}
});
Change 1D array into 2D array without using Numpy.
l = [i for i in range(1,21)]
part = 3
new = []
start, end = 0, part
while end <= len(l):
temp = []
for i in range(start, end):
temp.append(l[i])
new.append(temp)
start += part
end += part
print("new values: ", new)
# for uneven cases
temp = []
while start < len(l):
temp.append(l[start])
start += 1
new.append(temp)
print("new values for uneven cases: ", new)
If you would like to use autocomplete all the time without having to worry about hitting Ctrl + Spacebar or your own keyboard shortcut, you can make the following adjustment in the Eclipse preferences to trigger autocomplete simply by typing several different characters:
abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ._
Now any time that you type any of these characters, Eclipse will trigger autocomplete suggestions based on the context.
Surprised that nobody mentioned that zoom: 1;
is useful for IE6-7, to solve most IE-only bugs by triggering hasLayout.
Readonly will allow the user to copy text from it. Disabled will not.
No, unfortunately this will not be possible because ConverterParameter
is not a DependencyProperty
so you won't be able to use bindings
But perhaps you could cheat and use a MultiBinding
with IMultiValueConverter
to pass in the 2 Tag
properties.
Another possible solution is instead of passing a variable number of arguments to a stored procedure, pass a single string containing the names you're after, but make them unique by surrounding them with '<>'. Then use PATINDEX to find the names:
SELECT *
FROM Tags
WHERE PATINDEX('%<' + Name + '>%','<jo>,<john>,<scruffy>,<rubyonrails>') > 0
You're calling e.nextElement()
twice inside your loop when you're only guaranteed that you can call it once without an exception. Rewrite the loop like so:
while(e.hasMoreElements()){
String param = e.nextElement();
System.out.println(param);
}
Just like this worked for me on Github.

First, you need to add HttpHeaders with HttpClient
import { HttpClient,HttpHeaders } from '@angular/common/http';
your constructor should be like this.
constructor(private http: HttpClient) { }
then you can use like this
let header = new HttpHeaders({ "Authorization": "Bearer "+token});
const requestOptions = { headers: header};
return this.http.get<any>(url, requestOptions)
.toPromise()
.then(data=> {
//...
return data;

function convertTo24Hour(time) {
time = time.toUpperCase();
var hours = parseInt(time.substr(0, 2));
if(time.indexOf('AM') != -1 && hours == 12) {
time = time.replace('12', '0');
}
if(time.indexOf('PM') != -1 && hours < 12) {
time = time.replace(hours, (hours + 12));
}
return time.replace(/(AM|PM)/, '');
}
Add a CSS class called "pagebreak" (or "pb"), like so:
@media print {
.pagebreak { page-break-before: always; } /* page-break-after works, as well */
}
Then add an empty DIV tag (or any block element that generates a box) where you want the page break.
<div class="pagebreak"> </div>
It won't show up on the page, but will break up the page when printing.
P.S. Perhaps this only applies when using -after
(and also what else you might be doing with other <div>
s on the page), but I found that I had to augment the CSS class as follows:
@media print {
.pagebreak {
clear: both;
page-break-after: always;
}
}
I would use EXISTS
expression since it is more powerful, you can e.g. more precisely choose rows you would like to join. In the case of LEFT JOIN
, you have to take everything that's in the joined table. Its efficiency is probably the same as in the case of LEFT JOIN
with null constraint.
SELECT t1.ID
FROM Table1 t1
WHERE NOT EXISTS (SELECT t2.ID FROM Table2 t2 WHERE t1.ID = t2.ID)
Correct me if i'm wrong..
i could have used forEach
method like this,
var found=false;
vendors.forEach(function(item){
if(item.name === "name"){
found=true;
}
});
Nowadays i'm used to it ,because of it simplicity and self explanatory word. Thank you.
The for
attribute of the <label>
tag should be equal to the id
attribute of the related element to bind them together.
Useful sns.heatmap
api is here. Check out the parameters, there are a good number of them. Example:
import seaborn as sns
%matplotlib inline
idx= ['aaa','bbb','ccc','ddd','eee']
cols = list('ABCD')
df = DataFrame(abs(np.random.randn(5,4)), index=idx, columns=cols)
# _r reverses the normal order of the color map 'RdYlGn'
sns.heatmap(df, cmap='RdYlGn_r', linewidths=0.5, annot=True)
You need the following functions to do this in PHP:
strpos
Find the position of the first occurrence of a substring in a string
strrpos
Find the position of the last occurrence of a substring in a string
substr
Return part of a string
Here's the signature of the substr
function:
string substr ( string $string , int $start [, int $length ] )
The signature of the substring
function (Java) looks a bit different:
string substring( int beginIndex, int endIndex )
substring
(Java) expects the end-index as the last parameter, but substr
(PHP) expects a length.
It's not hard, to get the desired length by the end-index in PHP:
$sub = substr($str, $start, $end - $start);
Here is the working code
$start = strpos($message, '-') + 1;
if ($req_type === 'RMT') {
$pt_password = substr($message, $start);
}
else {
$end = strrpos($message, '-');
$pt_password = substr($message, $start, $end - $start);
}
DirBuster is such a hacking script that guesses a bunch of common names as nsanders had mentioned. It literally brute forces lists of common words and file endings (.html, .php) and over time figures out the directory structure of such sites, this could discover the page as you described but would also discover many others.
Very easy:
var stringArr = dataTable.Rows[0].ItemArray.Select(x => x.ToString()).ToArray();
Where DataRow.ItemArray
property is an array of objects containing the values of the row for each columns of the data table.
if I got it right, you can try
for item in [x for x in checklist if x not in mylist]:
print (item)
Starting from Spring Boot version 1.2.0.RELEASE , there is a property you can add to your application.properties
to set a default date format to all of your classes spring.jackson.date-format
.
For your date format example, you would add this line to your properties file:
spring.jackson.date-format=yyyy-MM-dd
You can use the function difftime
. It returns the difference between two given time_t
values, the output value is double
(see difftime documentation).
time_t actual_time;
double actual_time_sec;
actual_time = time(0);
actual_time_sec = difftime(actual_time,0);
printf("%g",actual_time_sec);
Use something like this (Not compiler checked)
NSMutableAttributedString *string = [[NSMutableAttributedString alloc]initWithString:self.text.text];
NSRange range=[self.myLabel.text rangeOfString:texts[sliderValue]]; //myLabel is the outlet from where you will get the text, it can be same or different
NSArray *colors=@[[UIColor redColor],
[UIColor redColor],
[UIColor yellowColor],
[UIColor greenColor]
];
[string addAttribute:NSForegroundColorAttributeName
value:colors[sliderValue]
range:range];
[self.scanLabel setAttributedText:texts[sliderValue]];
I found another solution for this problem. This looks like another bug in WebKit (or probably Chrome), but it works. All you need to do - is to add a WebKit CSS Mask to the #wrapper element. You can use a single pixel png image and even include it to the CSS to save a HTTP request.
#wrapper {
width: 300px; height: 300px;
border-radius: 100px;
overflow: hidden;
position: absolute; /* this breaks the overflow:hidden in Chrome/Opera */
/* this fixes the overflow:hidden in Chrome */
-webkit-mask-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAIAAACQd1PeAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAAA5JREFUeNpiYGBgAAgwAAAEAAGbA+oJAAAAAElFTkSuQmCC);
}
#box {
width: 300px; height: 300px;
background-color: #cde;
}?

The .pde file extension is the one used by the Processing, Wiring, and the Arduino IDE.
Processing is not C-based but rather Java-based and with a syntax derived from Java. It is a Java framework that can be used as a Java library. It includes a default IDE that uses .pde extension. Just wanted to rectify @kersny's answer.
Wiring is a microcontroller that uses the same IDE. Arduino uses a modified version, but also with .pde. The OpenProcessing page where you found it is a website to exhibit some Processing work.
If you know Java, it should be fairly easy to convert the Processing code to Java AWT.
This doesn't exactly answer the question but for anyone using AngularJS trying to achieve this, the answer is slightly different. And actually the normal answer won't work (at least it didn't for me).
Your html will look pretty similar to the normal radio button:
<input type='radio' name='group' ng-model='mValue' value='first' />First
<input type='radio' name='group' ng-model='mValue' value='second' /> Second
In your controller you'll have declared the mValue
that is associated with the radio buttons. To have one of these radio buttons preselected, assign the $scope
variable associated with the group to the desired input's value:
$scope.mValue="second"
This makes the "second" radio button selected on loading the page.
EDIT: Since AngularJS 2.x
The above approach does not work if you're using version 2.x and above. Instead use ng-checked
attribute as follows:
<input type='radio' name='gender' ng-model='genderValue' value='male' ng-checked='genderValue === male'/>Male
<input type='radio' name='gender' ng-model='genderValue' value='female' ng-checked='genderValue === female'/> Female
I think your overflow should be on the outer container. You can also explicitly set a min width for the columns. Like this:
.search-table-outter { overflow-x: scroll; }
th, td { min-width: 200px; }
Fiddle: http://jsfiddle.net/5WsEt/
In short: It's a shorthand notation for a mathematical hack.
Long explanation:
You can't do a cross product with vectors in 2D space. The operation is not defined there.
However, often it is interesting to evaluate the cross product of two vectors assuming that the 2D vectors are extended to 3D by setting their z-coordinate to zero. This is the same as working with 3D vectors on the xy-plane.
If you extend the vectors that way and calculate the cross product of such an extended vector pair you'll notice that only the z-component has a meaningful value: x and y will always be zero.
That's the reason why the z-component of the result is often simply returned as a scalar. This scalar can for example be used to find the winding of three points in 2D space.
From a pure mathematical point of view the cross product in 2D space does not exist, the scalar version is the hack and a 2D cross product that returns a 2D vector makes no sense at all.
I don't know SQLServer as well as other DBMS' but I imagine the benefit is the same as with DB2 and Oracle. If you use Windows authentication, you only have to maintain one set of users and/or passwords, that of Windows, which is already done for you.
DBMS authentication means having a separate set of users and/or passwords which must be maintained.
In addition, Windows passwords allow them to be configured centrally for the enterprise (Active Directory) whereas SQLServer has to maintain one set for each DBMS instance.
You should use the preprocessor macro __LINE__
and __FILE__
. They are predefined macros and part of the C/C++ standard. During preprocessing, they are replaced respectively by a constant string holding an integer representing the current line number and by the current file name.
Others preprocessor variables :
__func__
: function name (this is part of C99, not all C++ compilers support it)__DATE__
: a string of form "Mmm dd yyyy"__TIME__
: a string of form "hh:mm:ss"Your code will be :
if(!Logical)
printf("Not logical value at line number %d in file %s\n", __LINE__, __FILE__);
A web application is a website in the same way that a square is a rectangle.
The application part is the model-controller combo. The web part (the view) is why it qualifies as a website.
Something that is only a website and not a web application is simply missing the dynamic aspect.
Of course, it can be difficult to decide on how much server-side processing is required to qualify it as a web application. Probably when it has a data store.
Thus, you have the primary role of webapps confused. A website's primary role is to inform. A web app's primary role is to inform using dynamic content (the do something part).
You could call this function for each of the edit texts:
public boolean isEmpty(EditText editText) {
boolean isEmptyResult = false;
if (editText.getText().length() == 0) {
isEmptyResult = true;
}
return isEmptyResult;
}
Not to belabor the point, but if you are working in a Dockerfile
, you would solve this particular issue with Composer by installing the unzip
utility. Below is an example using the official PHP image to install unzip
and the zip
PHP extension for good measure.
FROM php:7.4-apache
# Install Composer
COPY --from=composer /usr/bin/composer /usr/bin/composer
# Install unzip utility and libs needed by zip PHP extension
RUN apt-get update && apt-get install -y \
zlib1g-dev \
libzip-dev \
unzip
RUN docker-php-ext-install zip
This is a helpful GitHub issue where the above is lovingly lifted from.
You must allow for more than a digit (the +
sign) as in:
String regex = "[0-9]+";
String data = "23343453";
System.out.println(data.matches(regex));
In Python 3, TemporaryDirectory in the tempfile module can be used.
This is straight from the examples:
import tempfile
with tempfile.TemporaryDirectory() as tmpdirname:
print('created temporary directory', tmpdirname)
# directory and contents have been removed
If you would like to keep the directory a bit longer, you could do something like this:
import tempfile
temp_dir = tempfile.TemporaryDirectory()
print(temp_dir.name)
# use temp_dir, and when done:
temp_dir.cleanup()
The documentation also says that "On completion of the context or destruction of the temporary directory object the newly created temporary directory and all its contents are removed from the filesystem." So at the end of the program, for example, Python will clean up the directory if it wasn't explicitly removed. Python's unittest
may complain of ResourceWarning: Implicitly cleaning up <TemporaryDirectory...
if you rely on this, though.
The href is probably generated in a javascript function. For example with jQuery:
$(function() {
$('a.view').attr('href', 'http://www.google.com');
});
You (still) can not choose the position of the column using ALTER TABLE: it can only be added to the end of the table. You can obviously select the columns in any order you want, so unless you are using SELECT * FROM column order shouldn't be a big deal.
If you really must have them in a particular order and you can't drop and recreate the table, then you might be able to drop and recreate columns instead:-
First copy the table
CREATE TABLE my_tab_temp AS SELECT * FROM my_tab;
Then drop columns that you want to be after the column you will insert
ALTER TABLE my_tab DROP COLUMN three;
Now add the new column (two in this example) and the ones you removed.
ALTER TABLE my_tab ADD (two NUMBER(2), three NUMBER(10));
Lastly add back the data for the re-created columns
UPDATE my_tab SET my_tab.three = (SELECT my_tab_temp.three FROM my_tab_temp WHERE my_tab.one = my_tab_temp.one);
Obviously your update will most likely be more complex and you'll have to handle indexes and constraints and won't be able to use this in some cases (LOB columns etc). Plus this is a pretty hideous way to do this - but the table will always exist and you'll end up with the columns in a order you want. But does column order really matter that much?
Based on Ray Nicholus's answer :
inputElement.onchange = function(event) {
var fileList = inputElement.files;
//TODO do something with fileList.
}
using this will also work :
inputElement.onchange = function(event) {
var fileList = event.target.files;
//TODO do something with fileList.
}
Querying across 2 different databases is a distributed query. Here is a list of some techniques plus the pros and cons:
I found a very easy process to find you MD5, SHA-1 fingerprint using Android Studio.
- Run your project
- Go to Gradle Menu (Menu: View -> Tool Windows -> Gradle)
- Go to 'signingReport' in Gradle window. (Your project -> Tasks -> android -> signingReport)
- Run it. (Using double-click or Ctrl + Shift + F10)
- In Run window you will find all info.
It's work only for debug mode. In realease mode I can not see sha-1.
Here result of gradlew signingReport

So I must use keytool to get sha-1. Here official Firebase doc:
To stop the window being resizeable once you've maximised it you need to change the FormBorderStyle
from Sizable
to one of the fixed constants:
FixedSingle
Fixed3D
FixedDialog
From the MSDN Page Remarks section:
The border style of the form determines how the outer edge of the form appears. In addition to changing the border display for a form, certain border styles prevent the form from being sized. For example, the FormBorderStyle.FixedDialog border style changes the border of the form to that of a dialog box and prevents the form from being resized. The border style can also affect the size or availability of the caption bar section of a form.
It will change the appearance of the form if you pick Fixed3D
for example, and you'll probably have to do some work if you want the form to restore to non-maximised and be resizeable again.
If you have a column called "col1" which is int, you cast it to String like this:
CONVERT(col1,char)
e.g. this allows you to check an int value is containing another value (here 9) like this:
CONVERT(col1,char) LIKE '%9%'
If you are doing complex, async input validation it might be worth it to abstract ng-model
up one level as part of a custom class with its own validation methods.

This is Andy's solution. I just addressed User2357112's concern and gave it meaningful variable names. I'm a Python rookie and preferred these functions.
def left(aString, howMany):
if howMany <1:
return ''
else:
return aString[:howMany]
def right(aString, howMany):
if howMany <1:
return ''
else:
return aString[-howMany:]
def mid(aString, startChar, howMany):
if howMany < 1:
return ''
else:
return aString[startChar:startChar+howMany]
All appender names must be reflected in the root section.
In your case the appender name is EventLogAppender but in the <root> <appender-ref ..
section it is named as ConsoleAppender. They need to match.
You can add multiple appenders to your log config but you need to register each of them in the <root>
section.
<appender-ref ref="ConsoleAppender" />
<appender-ref ref="EventLogAppender" />
You can also refer to the apache documentation on configuring log4net.
Adding some understanding.
By Euclidean definition the mod result must be always positive.
Ex:
int n = 5;
int x = -3;
int mod(int n, int x)
{
return ((n%x)+x)%x;
}
Output:
-1
You can also use COALESCE ( expression [ ,...n ] ) - returns first non-null like:
SELECT COALESCE(MAX(X),0) AS MaxX
FROM tbl
WHERE XID = 1

I just found my self with this Exception, I was trying to consume a JAX-WS, with a custom URL like this:
String WSDL_URL= <get value from properties file>;
Customer service = new Customer(new URL(WSDL_URL));
ExecutePtt port = service.getExecutePt();
return port.createMantainCustomers(part);
and Java threw:
XML reader error: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,63]
Message: White spaces are required between publicId and systemId.
Turns out that the URL string used to construct the service was missing the "?wsdl" at the end. For instance:
Bad:
http://www.host.org/service/Customer
Good:
http://www.host.org/service/Customer?wsdl
Related issue I had getting error 2 running source command: filename must not be in quotes even if it contains spaces in name or path to file.
When I try:
<input type="button" id="moreFields" onclick="alert('The text will be show!!'); return false;" value="Give me more fields!" />
It's worked well. So I think the problem is position of moreFields() function. Ensure that function will be define before your input tag.
Pls try:
<script type="text/javascript">
function moreFields() {
alert("The text will be show");
}
</script>
<input type="button" id="moreFields" onclick="moreFields()" value="Give me more fields!" />
Hope it helped.
For this particular relationship, you could use np.sign
:
>>> df["C"] = np.sign(df.A - df.B)
>>> df
A B C
a 2 2 0
b 3 1 1
c 1 3 -1
If you use Tomcat server I suggest you to put JSTL .jar file to the Tomcat lib folder. By doing this you will have an access to JSTL in all your web projects automatically (with taglib declaration in .jsp files of course).
In jQuery, you can use:
let myObject = {first:1, second:12, third:5};
jQuery.param(myObject);
Doc: http://api.jquery.com/jquery.param/ The output: first=1&second=12&third=5 This will format it, whatever your object contain.
To view the differences going from the remote file to the local file:
git diff remotename/branchname:remote/path/file1.txt local/path/file1.txt
To view the differences in the other direction:
git diff HEAD:local/path/file1.txt remotename/branchname:remote/path/file1.txt
Basically you can diff any two files anywhere using this notation:
git diff ref1:path/to/file1 ref2:path/to/file2
As usual, ref1
and ref2
could be branch names, remotename/branchname, commit SHAs, etc.
json strings can't have line breaks in them. You'd have to make it all one line: {"key":"val","key2":"val2",etc....}
.
But don't generate JSON strings yourself. There's plenty of libraries that do it for you, the biggest of which is jquery.

Long.MIN_VALUE.
Heap just guarantees that elements on higher levels are greater (for max-heap) or smaller (for min-heap) than elements on lower levels
I love the above answer and putting my comment just more specific to my need and usage. I had to get the n locations list find the distance from each location to specific point say (0,0) and then return the a m locations having smaller distance. I used Priority Queue which is Heap. For finding distances and putting in heap it took me n(log(n)) n-locations log(n) each insertion. Then for getting m with shortest distances it took m(log(n)) m-locations log(n) deletions of heaping up.
I if would have to do this with BST, it would have taken me n(n) worst case insertion.(Say the first value is very smaller and all other comes sequentially longer and longer and the tree spans to right child only or left child in case of smaller and smaller. The min would have taken O(1) time but again I had to balance. So from my situation and all above answers what I got is when you are only after the values at min or max priority basis go for heap.
Since the page you load inside the iframe can execute the "break out" code with a setInterval, onbeforeunload might not be that practical, since it could flud the user with 'Are you sure you want to leave?' dialogs.
There is also the iframe security attribute which only works on IE & Opera

For Staging Area vs Repository(last commit) comparison use
$git diff --staged
The command compares your staged($ git add fileName
) changes to your last commit. If you want to see what you’ve staged that will go into your next commit, you can use git diff --staged. This command compares your staged changes to your last commit.
For Working vs Staging comparison use
$ git diff
The command compares what is in your working directory with what is in your staging area. It’s important to note that git diff by itself doesn’t show all changes made since your last commit — only changes that are still unstaged. If you’ve staged all of your changes($ git add fileName
), git diff will give you no output.
Also, if you stage a file($ git add fileName
) and then edit it, you can use git diff to see the changes in the file that are staged and the changes that are unstaged.

You could use the library lxml (Note top level link is now spam) , which is a superset of ElementTree. Its tostring() method includes a parameter pretty_print - for example:
>>> print(etree.tostring(root, pretty_print=True))
<root>
<child1/>
<child2/>
<child3/>
</root>
First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:
<form method="post" enctype="multipart/form-data" action="/upload">
<input type="file" name="file">
<input type="submit" value="Submit">
</form>
Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:
const http = require("http");
const path = require("path");
const fs = require("fs");
const express = require("express");
const app = express();
const httpServer = http.createServer(app);
const PORT = process.env.PORT || 3000;
httpServer.listen(PORT, () => {
console.log(`Server is listening on port ${PORT}`);
});
// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));
Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).
In Express 3.x you could use express.bodyParser
middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:
You need to define a route to handle form posts:
const multer = require("multer");
const handleError = (err, res) => {
res
.status(500)
.contentType("text/plain")
.end("Oops! Something went wrong!");
};
const upload = multer({
dest: "/path/to/temporary/directory/to/store/uploaded/files"
// you might also want to set some limits: https://github.com/expressjs/multer#limits
});
app.post(
"/upload",
upload.single("file" /* name attribute of <file> element in your form */),
(req, res) => {
const tempPath = req.file.path;
const targetPath = path.join(__dirname, "./uploads/image.png");
if (path.extname(req.file.originalname).toLowerCase() === ".png") {
fs.rename(tempPath, targetPath, err => {
if (err) return handleError(err, res);
res
.status(200)
.contentType("text/plain")
.end("File uploaded!");
});
} else {
fs.unlink(tempPath, err => {
if (err) return handleError(err, res);
res
.status(403)
.contentType("text/plain")
.end("Only .png files are allowed!");
});
}
}
);
In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.
In order to show the uploaded image, assuming you already have an HTML page containing an img element:
<img src="/image.png" />
you can define another route in your express app and use res.sendFile
to serve the stored image:
app.get("/image.png", (req, res) => {
res.sendFile(path.join(__dirname, "./uploads/image.png"));
});
If order is not the matter:
>>> foo='mppmt'
>>> ''.join(set(foo))
'pmt'
To keep the order:
>>> foo='mppmt'
>>> ''.join([j for i,j in enumerate(foo) if j not in foo[:i]])
'mpt'
For guys like me, who aren't minimalistic, there is a PECL extension called "intl". I use it for idn conversion since it works way better than the "idn" extension and some other n1 classes like "IntlDateFormatter".
Well, what I want to say is, the "intl" extension has a class called "IntlCalendar" which can handle many international countries (e.g. in Saudi Arabia, sunday is not a weekend day). The IntlCalendar has a method IntlCalendar::isWeekend for that. Maybe you guys give it a shot, I like that "it works for almost every country" fact on these intl-classes.
EDIT: Not quite sure but since PHP 5.5.0, the intl extension is bundled with PHP (--enable-intl).
seeing how the rules are fairly complicated, I'd suggest the following:
/^[a-z](\w*)[a-z0-9]$/i
match the whole string and capture intermediate characters. Then either with the string functions or the following regex:
/__/
check if the captured part has two underscores in a row. For example in Python it would look like this:
>>> import re
>>> def valid(s):
match = re.match(r'^[a-z](\w*)[a-z0-9]$', s, re.I)
if match is not None:
return match.group(1).count('__') == 0
return False
This thing can easily be done by implementing a public class that implements Comparable. This will allow you to use compareTo method which can be used with any other object to which you wish to compare.
for example you can implement it in this way:
public String compareTo(Animal oth)
{
return String.compare(this.population, oth.population);
}
I think this might solve your purpose.
Sometimes you need to reset ADB. To do that, in Eclipse, go:
Window>> Show View >> Android (Might be found in the "Other" option)>>Devices
in the device Tab, click the down arrow, and choose reset adb.
the solution isn't good. one could "mousedown" on the document, then "mouseup" outside the browser, and on this case the browser would still be thinking the mouse is down.
the only good solution is using IE.event object.
I think this method produces very good results:

There are multiple classes that are grouped together as "numeric" classes, the 2 most common of which are double (for double precision floating point numbers) and integer. R will automatically convert between the numeric classes when needed, so for the most part it does not matter to the casual user whether the number 3 is currently stored as an integer or as a double. Most math is done using double precision, so that is often the default storage.
Sometimes you may want to specifically store a vector as integers if you know that they will never be converted to doubles (used as ID values or indexing) since integers require less storage space. But if they are going to be used in any math that will convert them to double, then it will probably be quickest to just store them as doubles to begin with.
It should be a Python expression that, when eval'd, creates an object with the exact same properties as this one. For example, if you have a Fraction
class that contains two integers, a numerator and denominator, your __repr__()
method would look like this:
# in the definition of Fraction class
def __repr__(self):
return "Fraction(%d, %d)" % (self.numerator, self.denominator)
Assuming that the constructor takes those two values.
Save function:
$shopOwner->save()
already do what you want...
Laravel code:
// If the model already exists in the database we can just update our record
// that is already in this database using the current IDs in this "where"
// clause to only update this model. Otherwise, we'll just insert them.
if ($this->exists)
{
$saved = $this->performUpdate($query);
}
// If the model is brand new, we'll insert it into our database and set the
// ID attribute on the model to the value of the newly inserted row's ID
// which is typically an auto-increment value managed by the database.
else
{
$saved = $this->performInsert($query);
}
I would like to run an automation test in different environments.

You can separate multiple classes with the space:
$("p").addClass("myClass yourClass");
Try to put all your <script ...></script>
tags before the </body>
tag. Perhaps the js is trying to access an object of the DOM before it's built up.
Mysqli makes use of object oriented programming. Try using this approach instead:
function dbCon() {
if($mysqli = new mysqli('$hostname','$username','$password','$databasename')) return $mysqli; else return false;
}
if(!dbCon())
exit("<script language='javascript'>alert('Unable to connect to database')</script>");
else $con=dbCon();

If you don't want to build Tensorflow yourself and your operating system is Debian or Ubuntu, you can download prebuilt packages with the Tensorflow C/C++ libraries. This distribution can be used for C/C++ inference with CPU, GPU support is not included:

The latest way to go is to use the unit 'ch' which stands for character.
You can simply write:
p {
max-width: 75ch;
}
The only trick is that whitespaces won't be counted as characters..

This could be done using List::Util's first

Other functions from List::Util

For future googlers:
This message will be generated if the server-side function crashes.
Or if the server-side function doesn't even exist ( i.e. Typo in function name ).

The problem with iPhone camera is that the first models (of which there are tons in use) have a fixed-focus camera that cannot take picture in-focus for distances under 2ft. The images are blurry and distorted and if taken from greater distance there is not enough detail/information from the barcode.
A few companies have developed iPhone apps that can accomodate for that by using advanced de-blurring technologies. Those applications you can find on Apple app store: pic2shop, RedLaser and ShopSavvy. All of the companies have announced that they have also SDKs available - some for free or very preferential terms, check that one out.
It should also be mentioned, that Set-PSDebug is similar to the old-school echo on
batch command:
Set-PSDebug -Trace 1
This command will result in showing every line of the executing script:
When the
Trace
parameter has a value of1
, each line of script is traced as it runs. When the parameter has a value of2
, variable assignments, function calls, and script calls are also traced. If theStep
parameter is specified, you're prompted before each line of the script runs.
mkdir -p

So a refinement to the previous suggestions would be to re-raise
the exception if os.path.isdir
returns False
(when checking for errno.EEXIST
).
(Update) See also this highly similar question; I agree with the accepted answer (and caveats) except I would recommend os.path.isdir
instead of os.path.exists
.
(Update) Per a suggestion in the comments, the full function would look like:
import os
def mkdirp(directory):
if not os.path.isdir(directory):

public class ReplaceString{
public static void main(String[] args)throws Exception {
if(args.length<3)System.exit(0);
String targetStr = args[1];
String altStr = args[2];
java.io.File file = new java.io.File(args[0]);
java.util.Scanner scanner = new java.util.Scanner(file);
StringBuilder buffer = new StringBuilder();
while(scanner.hasNext()){
buffer.append(scanner.nextLine().replaceAll(targetStr, altStr));
if(scanner.hasNext())buffer.append("\n");
}
scanner.close();
java.io.PrintWriter printer = new java.io.PrintWriter(file);
printer.print(buffer);
printer.close();
}
}
There are two ways. In case of doubt, you can always just try it. If it does not work, you can add extra braces to make sure, like that:
if not ((u0 <= u) and (u < u0+step)):
You may also use math.log1p
.
According to the official documentation :
math.log1p(x)
Return the natural logarithm of 1+x (base e). The result is calculated in a way which is accurate for x near zero.
You may convert back to the original value using math.expm1
which returns e
raised to the power x, minus 1.
You can just use "!important" to get your custom color
.navbar {
background-color: yourcolor !important;
}
In my case the error was appearing because I had uploaded the whole folder, containing the website files, into the container.
I solved it by moving all the files outside the folder, right into the container.
Here is full code. The result is exactly what you want.
class Animal(object):
def __init__(self):
self.legs = 2
self.name = 'Dog'
self.color= 'Spotted'
self.smell= 'Alot'
self.age = 10
self.kids = 0
if __name__ == '__main__':
animal = Animal()
temp = vars(animal)
for item in temp:
print item , ' : ' , temp[item]
#print item , ' : ', temp[item] ,
request.getParameter()
We use request.getParameter()
to extract request parameters (i.e. data sent by posting a html form ). The request.getParameter()
always returns String
value and the data come from client.
request.getAttribute()
We use request.getAttribute()
to get an object added to the request scope on the server side i.e. using request.setAttribute()
. You can add any type of object you like here, Strings
, Custom objects, in fact any object. You add the attribute to the request and forward the request to another resource, the client does not know about this. So all the code handling this would typically be in JSP/servlets. You can use request.setAttribute()
to add extra-information and forward/redirect the current request to another resource.
For example,consider about first.jsp,
//First Page : first.jsp
<%@ page import="java.util.*" import="java.io.*"%>
<% request.setAttribute("PAGE", "first.jsp");%>
<jsp:forward page="/second.jsp"/>
and second.jsp:
<%@ page import="java.util.*" import="java.io.*"%>
From Which Page : <%=request.getAttribute("PAGE")%><br>
Data From Client : <%=request.getParameter("CLIENT")%>
From your browser, run first.jsp?CLIENT=you and the output on your browser is
From Which Page : *first.jsp*
Data From Client : you
The basic difference between getAttribute()
and getParameter()
is that the first method extracts a (serialized) Java object and the other provides a String value. For both cases a name is given so that its value (be it string or a java bean) can be looked up and extracted.
I have done it like that
<%= form_for :user, url: {action: "update", params: {id: @user.id}} do |f| %>
Note the optional parameter id
set to user instance id attribute.
put the id you want to check in jquery is method.
var idcheck = $("selector").is("#id");
if(idcheck){ // if the selector contains particular id
// your code if particular Id is there
}
else{
// your code if particular Id is NOT there
}
<style>
form div {
width: 400px;
border: 1px solid black;
}
form input[type='submit'] {
display: inline-block;
width: 70px;
}
div.submitWrapper {
text-align: center;
}
</style>
<form>
<div class='submitWrapper'>
<input type='submit' name='submit' value='Submit'>

Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.
In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.
Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.
Is m_cRedundencyManager
able to use member functions? Most callbacks are set up to use regular functions or static member functions. Take a look at this page at C++ FAQ Lite for more information.
Update: The function declaration you provided shows that m_cRedundencyManager
is expecting a function of the form: void yourCallbackFunction(int, void *)
. Member functions are therefore unacceptable as callbacks in this case. A static member function may work, but if that is unacceptable in your case, the following code would also work. Note that it uses an evil cast from void *
.
// in your CLoggersInfra constructor:
m_cRedundencyManager->Init(myRedundencyManagerCallBackHandler, this);
// in your CLoggersInfra header:
void myRedundencyManagerCallBackHandler(int i, void * CLoggersInfraPtr);
// in your CLoggersInfra source file:
void myRedundencyManagerCallBackHandler(int i, void * CLoggersInfraPtr)
{
((CLoggersInfra *)CLoggersInfraPtr)->RedundencyManagerCallBack(i);
}
First, elements inside a collection print their repr. you should learn about __repr__
and __str__
.
This is the difference between print repr(1.1) and print 1.1. Let's join all those strings instead of the representations:
numbers = [9.0, 0.053, 0.0325754, 0.0108928, 0.0557025, 0.07933]
print "repr:", " ".join(repr(n) for n in numbers)
print "str:", " ".join(str(n) for n in numbers)
To answer the questions in terms of how you asked it.
This is actually REALLY easy (in Internet Explorer, at least), i did it in like 17.5 seconds.
If you use the custom script that cxfx provided: (place it in your apsx file)
<script language="VBScript">
Sub myAlert(title, content)
MsgBox content, 0, title
End Sub
</script>
You can then call it just like you called the regular alert. Just modify your code to the following.
Response.Write("<script language=JavaScript> myAlert('Message Header Here','Hi select a valid date'); </script>");
Hope that helps you, or someone else!
First of all this code snippet
char *addr=NULL;
strcpy(addr,retstring().c_str());
is invalid because you did not allocate memory where you are going to copy retstring().c_str().
As for the error message then it is clear enough. The type of expression data.str().c_str() is const char * but the third parameter of the function is declared as char *. You may not assign an object of type const char * to an object of type char *. Either the function should define the third parameter as const char * if it does not change the object pointed by the third parameter or you may not pass argument of type const char *.
Looking at the controller, and learing a bit more about how MVC actually works, I was able to make sense of this.
My view was one of the auto-generated ones, and contained this line of code:
@Html.DropDownList("PriorityID", string.Empty)
To add html attributes, I needed to do something like this:
@Html.DropDownList("PriorityID", (IEnumerable<SelectListItem>)ViewBag.PriorityID, new { @class="dropdown" })
Thanks again to @Laurent for your help, I realise the question wasn't as clear as it could have been...
UPDATE:
A better way of doing this would be to use DropDownListFor where possible, that way you don't rely on a magic string for the name attribute
@Html.DropDownListFor(x => x.PriorityID, (IEnumerable<SelectListItem>)ViewBag.PriorityID, new { @class = "dropdown" })

You can check an example in Plunker over here plunker example filters
filter() {
let storeId = 1;
this.bookFilteredList = this.bookList
.filter((book: Book) => book.storeId === storeId);
this.bookList = this.bookFilteredList;
}
With lambda function
df['column'] = df['column'].apply(lambda x : x if x > 0 else 0)
strlist =[{}]*10
strlist[0] = set()
strlist[0].add("Beef")
strlist[0].add("Fish")
strlist[1] = {"Apple", "Banana"}
strlist[1].add("Cherry")
print(strlist[0])
print(strlist[1])
print(strlist[2])
print("Array size:", len(strlist))
print(strlist)
An alternative is to use OFFSET:
Assuming the column value is stored in B1, you can use the following
C1 = OFFSET(A1, 0, B1 - 1)
This works by:
a) taking a base cell (A1)
b) adding 0 to the row (keeping it as A)
c) adding (A5 - 1) to the column
You can also use another value instead of 0 if you want to change the row value too.

I stumbled upon this post recently and think that it needs an updated solution for the standard library's c++11 mutex (namely std::mutex).
I've pasted some code below (my first steps with a mutex - I learned concurrency on win32 with HANDLE, SetEvent, WaitForMultipleObjects etc).
Since it's my first attempt with std::mutex and friends, I'd love to see comments, suggestions and improvements!
#include <condition_variable>
#include <mutex>
#include <algorithm>
#include <thread>
#include <queue>
#include <chrono>
#include <iostream>
int _tmain(int argc, _TCHAR* argv[])
{
// these vars are shared among the following threads
std::queue<unsigned int> nNumbers;
std::mutex mtxQueue;
std::condition_variable cvQueue;
bool m_bQueueLocked = false;
std::mutex mtxQuit;
std::condition_variable cvQuit;
bool m_bQuit = false;
std::thread thrQuit(
[&]()
{
using namespace std;
this_thread::sleep_for(chrono::seconds(5));
// set event by setting the bool variable to true
// then notifying via the condition variable
m_bQuit = true;
cvQuit.notify_all();
}
);
std::thread thrProducer(
[&]()
{
using namespace std;
int nNum = 13;
unique_lock<mutex> lock( mtxQuit );
while ( ! m_bQuit )
{
while( cvQuit.wait_for( lock, chrono::milliseconds(75) ) == cv_status::timeout )
{
nNum = nNum + 13 / 2;
unique_lock<mutex> qLock(mtxQueue);
cout << "Produced: " << nNum << "\n";
nNumbers.push( nNum );
}
}
}
);
std::thread thrConsumer(
[&]()
{
using namespace std;
unique_lock<mutex> lock(mtxQuit);
while( cvQuit.wait_for(lock, chrono::milliseconds(150)) == cv_status::timeout )
{
unique_lock<mutex> qLock(mtxQueue);
if( nNumbers.size() > 0 )
{
cout << "Consumed: " << nNumbers.front() << "\n";
nNumbers.pop();
}
}
}
);
thrQuit.join();
thrProducer.join();
thrConsumer.join();
return 0;
}

Base on accepted answer, I made an extension method to check column exist in table as
I shared for whom concern.
public static class DatatableHelper
{
public static bool ContainColumn(this DataTable table, string columnName)
{
DataColumnCollection columns = table.Columns;
if (columns.Contains(columnName))
{
return true;
}
return false;
}
}
And use as dtTagData.ContainColumn("SystemName")
Below code works for me
first I defined the partnerTypesMap
like below in the server side,
Map<String, String> partnerTypes = new HashMap<>();
after adding values to it I added the object to model
,
model.addAttribute("partnerTypesMap", partnerTypes);
When rendering the page I use below foreach
to print them one by one.
<c:forEach items="${partnerTypesMap}" var="partnerTypesMap">
<form:option value="${partnerTypesMap['value']}">${partnerTypesMap['key']}</form:option>
</c:forEach>
I learned from the Search Engine(My English is very bad , So code...) How to get variable's type? Up's :
String str = "test";
String type = str.getClass().getName();
value: type = java.lang.String
this method :
str.getClass().getSimpleName();
value:String
now example:
Object o = 1;
o.getClass().getSimpleName();
value:Integer
SELECT CAST(<COLUMN Name> AS VARCHAR(3)) + ','
FROM <TABLE Name>
FOR XML PATH('')
You can also use string.match().
var string1 = "aBc";
var match = string1.match(/AbC/i);
if(match) {
}
Looks like this is unimplemented, as of the time of this writing:
https://github.com/sass/sass/issues/193
For libsass (C/C++ implementation), import works for *.css
the same way as for *.scss
files - just omit the extension:
@import "path/to/file";
This will import path/to/file.css
.
See this answer for further details.
See this answer for Ruby implementation (sass gem)
You can.

I am running into a similar problem. PUT on a sub-resource seems to work when you want to update only a single field. However, sometimes you want to update a bunch of things: Think of a web form representing the resource with option to change some entries. The user's submission of form should not result in a multiple PUTs.
Here are two solution that I can think of:
do a PUT with the entire resource. On the server-side, define the semantics that a PUT with the entire resource ignores all the values that haven't changed.
do a PUT with a partial resource. On the server-side, define the semantics of this to be a merge.
2 is just a bandwidth-optimization of 1. Sometimes 1 is the only option if the resource defines some fields are required fields (think proto buffers).
The problem with both these approaches is how to clear a field. You will have to define a special null value (especially for proto buffers since null values are not defined for proto buffers) that will cause clearing of the field.

Huffman has a static cost, the Huffman table, so I disagree it's a good choice.
There are adaptative versions which do away with this, but the compression rate may suffer. Actually, the question you should ask is "what algorithm to compress text strings with these characteristics". For instance, if long repetitions are expected, simple Run-Lengh Encoding might be enough. If you can guarantee that only English words, spaces, punctiation and the occasional digits will be present, then Huffman with a pre-defined Huffman table might yield good results.
Generally, algorithms of the Lempel-Ziv family have very good compression and performance, and libraries for them abound. I'd go with that.
With the information that what's being compressed are URLs, then I'd suggest that, before compressing (with whatever algorithm is easily available), you CODIFY them. URLs follow well-defined patterns, and some parts of it are highly predictable. By making use of this knowledge, you can codify the URLs into something smaller to begin with, and ideas behind Huffman encoding can help you here.
For example, translating the URL into a bit stream, you could replace "http" with the bit 1, and anything else with the bit "0" followed by the actual procotol (or use a table to get other common protocols, like https, ftp, file). The "://" can be dropped altogether, as long as you can mark the end of the protocol. Etc. Go read about URL format, and think on how they can be codified to take less space.
This error is encountered when the primary key of a table is updated but it is referenced by a foreign key from another table and the update specific is set to No action. The No action is the default option.
If this is your case and No action is set on the update operation you can change the foreign-key definition to Cascade.
Right click your foreign key and select Modify. In the Foreign key relationships dialog under the INSERT and UPDATE specifics set the UPDATE rule on Cascade:
You can also set the rule using T-SQL:
ALTER TABLE YourTable
DROP Constraint Your_FK
GO
ALTER TABLE YourTable
ADD CONSTRAINT [New_FK_Constraint]
FOREIGN KEY (YourColumn) REFERENCES ReferencedTable(YourColumn)
ON DELETE CASCADE ON UPDATE CASCADE
GO
Hope this helps
I have a simple approach to stopping spammers which is 100% effective, at least in my experience, and avoids the use of reCAPTCHA and similar approaches. I went from close to 100 spams per day on one of my sites' html forms to zero for the last 5 years once I implemented this approach.
It works by taking advantage of the e-mail ALIAS capabilities of most html form handling scripts (I use FormMail.pl), along with a graphic submission "code", which is easily created in the most simple of graphics programs. One such graphic includes the code M19P17nH and the prompt "Please enter the code at left".
This particular example uses a random sequence of letters and numbers, but I tend to use non-English versions of words familiar to my visitors (e.g. "pnofrtay"). Note that the prompt for the form field is built into the graphic, rather than appearing on the form. Thus, to a robot, that form field presents no clue as to its purpose.
The only real trick here is to make sure that your form html assigns this code to the "recipient" variable. Then, in your mail program, make sure that each such code you use is set as an e-mail alias, which points to whatever e-mail addresses you want to use. Since there is no prompt of any kind on the form for a robot to read and no e-mail addresses, it has no idea what to put in the blank form field. If it puts nothing in the form field or anything except acceptable codes, the form submission fails with a "bad recipient" error. You can use a different graphic on different forms, although it isn't really necessary in my experience.
Of course, a human being can solve this problem in a flash, without all the problems associated with reCAPTCHA and similar, more elegant, schemes. If a human spammer does respond to the recipient failure and programs the image code into the robot, you can change it easily, once you realize that the robot has been hard-coded to respond. In five years of using this approach, I've never had a spam from any of the forms on which I use it nor have I ever had a complaint from any human user of the forms. I'm certain that this could be beaten with OCR capability in the robot, but I've never had it happen on any of my sites which use html forms. I have also used "spam traps" (hidden "come hither" html code which points to my anti-spam policies) to good effect, but they were only about 90% effective.
I think that CodeRush has a free, limited version, too. I ended up going with ReSharper, and I still recommend it, even though some of the functionality is in Visual Studio 2010. There are just some things that make it worth it.
Keep in mind that you don't need the full ReSharper license if you only code in one language. I have the C# version, and it's cheaper.
Should update the figure caption automatically.
My question is tho, how can one also 'assign' referenced figures '(Fig.4)' in the text to do the same thing - aka change when an image is added above it?
EDIT: Figured it out.. In word go to Insert and Cross-ref and assign the ref. Then Ctrl+A and F9 and everything should sort itself out.
You need to use a regular expression, so that you can specify the global (g) flag:
var s = 'some+multi+word+string'.replace(/\+/g, ' ');
(I removed the $()
around the string, as replace
is not a jQuery method, so that won't work at all.)
You can make you request headers by yourself using:
// open a socket connection on port 80
$fp = fsockopen($host, 80);
// send the request headers:
fputs($fp, "POST $path HTTP/1.1\r\n");
fputs($fp, "Host: $host\r\n");
fputs($fp, "Referer: $referer\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ". strlen($data) ."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $data);
$result = '';
while(!feof($fp)) {
// receive the results of the request
$result .= fgets($fp, 128);
}
// close the socket connection:
fclose($fp);
Like writen on how make request
This is probably due to CORS (or not quoting paths) and is expected behaviour. I know it sounds confusing, but the reason is due to the source of your fonts and not the web page itself.

The first option in @Nathan Skerl's list is what was implemented in a project I once worked with, where a similar relationship was established between three tables. (One of them referenced two others, one at a time.)
So, the referencing table had two foreign key columns, and also it had a constraint to guarantee that exactly one table (not both, not neither) was referenced by a single row.
Here's how it could look when applied to your tables:
CREATE TABLE dbo.[Group]
(
ID int NOT NULL CONSTRAINT PK_Group PRIMARY KEY,
Name varchar(50) NOT NULL
);
CREATE TABLE dbo.[User]
(
ID int NOT NULL CONSTRAINT PK_User PRIMARY KEY,
Name varchar(50) NOT NULL
);
CREATE TABLE dbo.Ticket
(
ID int NOT NULL CONSTRAINT PK_Ticket PRIMARY KEY,
OwnerGroup int NULL
CONSTRAINT FK_Ticket_Group FOREIGN KEY REFERENCES dbo.[Group] (ID),
OwnerUser int NULL
CONSTRAINT FK_Ticket_User FOREIGN KEY REFERENCES dbo.[User] (ID),
Subject varchar(50) NULL,
CONSTRAINT CK_Ticket_GroupUser CHECK (
CASE WHEN OwnerGroup IS NULL THEN 0 ELSE 1 END +
CASE WHEN OwnerUser IS NULL THEN 0 ELSE 1 END = 1
)
);
As you can see, the Ticket
table has two columns, OwnerGroup
and OwnerUser
, both of which are nullable foreign keys. (The respective columns in the other two tables are made primary keys accordingly.) The CK_Ticket_GroupUser
check constraint ensures that only one of the two foreign key columns contains a reference (the other being NULL, that's why both have to be nullable).
(The primary key on Ticket.ID
is not necessary for this particular implementation, but it definitely wouldn't harm to have one in a table like this.)
You had thead
in your selector, but there is no thead
in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr
class to the th
, not vice-versa (although your comment seems to contradict what you wrote up above).
$('tr th').each(function(index){ if($('tr td').eq(index).attr('class') != ''){ // get the class of the td var tdClass = $('tr td').eq(index).attr('class'); // add it to this th $(this).addClass(tdClass ); } });
Additionally to what Chris Taylor wrote: if you have something serialized as an attribute, you can have a property on your class named {PropertyName}Specified
to control if it should be serialized. In code:
public class MyClass

This is a quick tutorial on how to get Python 3.7 working with Mysql
Thanks to all from who I got answers to my questions
- hope this helps somebody someday.
----------------------------------------------------
My System:
Windows Version: Pro 64-bit
REQUIREMENTS.. download and install these first...
1. Download Xampp..
https://www.apachefriends.org/download.html
2. Download Python
https://www.python.org/downloads/windows/
--------------
//METHOD
--------------
Install xampp first after finished installing - install Python 3.7.
Once finished installing both - reboot your windows system.
Now start xampp and from the control panel - start the mysql server.
Confirm the versions by opening up CMD and in the terminal type
c:\>cd c:\xampp\mysql\bin
c:\xampp\mysql\bin>mysql -h localhost -v
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 2
Server version: 10.1.21-MariaDB mariadb.org binary distribution
Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.
This is to check the MYSQL version
c:\xampp\mysql\bin>python
Python 3.7.0b3 (v3.7.0b3:4e7efa9c6f, Mar 29 2018, 18:42:04) [MSC v.1913 64 bit (AMD64)] on win32
This is to check the Python version
Now that both have been confirmed type the following into the CMD...
c:\xampp\mysql\bin>pip install pymysql
After the install of pymysql is completed.
create a new file called "testconn.py" on your desktop or whereever for quick access.
Open this file with sublime or another text editor and put this into it.
Remember to change the settings to reflect your database.
#!/usr/bin/python
import pymysql
pymysql.install_as_MySQLdb()
import MySQLdb
db = MySQLdb.connect(user="yourusernamehere",passwd="yourpasswordhere",host="yourhosthere",db="yourdatabasehere")
cursor = db.cursor()
cursor.execute("SELECT * from yourmysqltablehere")
data=cursor.fetchall()
for row in data :
print (row)
db.close()
Now in your CMD - type
c:\Desktop>testconn.py
And thats it... your now fully connected from a python script to mysql...
Enjoy...
Further to Andrew Wang's answer: if the BitConverter method is too slow but you cannot use unsafe code in your project, this struct is ~6x quicker than BitConverter:
[StructLayout(LayoutKind.Explicit)]
public struct FloatToIntSafeBitConverter
{
public static int Convert(float value)
{
return new FloatToIntSafeBitConverter(value).IntValue;
}
public FloatToIntSafeBitConverter(float floatValue): this()
{
FloatValue = floatValue;
}
[FieldOffset(0)]
public readonly int IntValue;
[FieldOffset(0)]
public readonly float FloatValue;
}
(Incidentally, I tried using the accepted solution but it (well my conversion at least) failed some of the unit tests also mentioned in the answer. e.g. assertTrue(nearlyEqual(Float.MIN_VALUE, -Float.MIN_VALUE));
)
Based on Illya Krit's answer
import Alamofire
struct BodyStringEncoding: ParameterEncoding {
private let body: String
init(body: String) { self.body = body }
func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
guard var urlRequest = urlRequest.urlRequest else { throw Errors.emptyURLRequest }
guard let data = body.data(using: .utf8) else { throw Errors.encodingProblem }
urlRequest.httpBody = data
return urlRequest
}
}
extension BodyStringEncoding {
enum Errors: Error {
case emptyURLRequest
case encodingProblem
}
}
extension BodyStringEncoding.Errors: LocalizedError {
var errorDescription: String? {
switch self {
case .emptyURLRequest: return "Empty url request"
case .encodingProblem: return "Encoding problem"
}
}
}
Alamofire.request(url, method: .post, parameters: nil, encoding: BodyStringEncoding(body: text), headers: headers).responseJSON { response in
print(response)
}
You can do it without any additional controls and libraries, using only Image control and transform:
<Image
Source="/images/spinner.png"
Width="100"
Height="100"
RenderTransformOrigin="0.5, 0.5" Visibility="{Binding IsLoading, Converter={StaticResource BooleanToVisibilityConverter}}">
<Image.RenderTransform>
<RotateTransform x:Name="noFreeze" />
</Image.RenderTransform>
<Image.Triggers>
<EventTrigger RoutedEvent="Loaded">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation
Storyboard.TargetProperty="(Image.RenderTransform).(RotateTransform.Angle)"
To="360" Duration="0:0:1" RepeatBehavior="Forever" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Image.Triggers>
</Image>
Replace /images/spinner.png
with your image. Change To="360"
to To="-360"
if you want to rotate it counterclockwise. Duration="0:0:1"
equals to 1 second per rotation.
Eli Courtwright second solution is wrong, it should be:
Calendar c = Calendar.getInstance();
c.setTime(date);
c.add(Calendar.DATE, -days);
date.setTime(c.getTime().getTime());
The error may be that you need to change the permission of folder and file which you are going to access. If like GoDaddy service you can access the file and change the permission or by ssh use the command like:
sudo chmod 777 file.jpeg
and then you can access if the above mentioned problems are not your case.
You could try this code:
private float GetBrightestColor(float r, float g, float b) {
if (r > g && r > b) {
return r;
} else if (g > r && g > b) {
return g;
} else if (b > r && b > g) {
return b;
}
}
with pure jquery:
window.jQuery.ajax({
type: "POST",
url: ajaxUrl,
contentType: 'application/json',
success: function (data) {
var odd_even = false;
var response = JSON.parse(data);
var head = "<thead class='thead-inverse'><tr>";
$.each(response[0], function (k, v) {
head = head + "<th scope='row'>" + k.toString() + "</th>";
})
head = head + "</thead></tr>";
$(table).append(head);//append header
var body="<tbody><tr>";
$.each(response, function () {
body=body+"<tr>";
$.each(this, function (k, v) {
body=body +"<td>"+v.toString()+"</td>";
})
body=body+"</tr>";
})
body=body +"</tbody>";
$(table).append(body);//append body
},
error: function (xhr, ajaxOptions, thrownError) {
alert(xhr.responsetext);
}
});
The difference is exactly what the name implies: a group by performs a grouping operation, and an order by sorts.
If you do SELECT * FROM Customers ORDER BY Name
then you get the result list sorted by the customers name.
If you do SELECT IsActive, COUNT(*) FROM Customers GROUP BY IsActive
you get a count of active and inactive customers. The group by aggregated the results based on the field you specified.
Make sure your first network interface is NAT. The other second network interface can be anything you want when you're building box. Don't forget the Vagrant user, as discussed in the Google thread.
Good luck.
Mime type option is not best option for validating CSV file. I used this code this worked well in all browser
$type = explode(".",$_FILES['file']['name']);
if(strtolower(end($type)) == 'csv'){
}
else
{
}
