If you are working with Source safe then make a new directory and take the latest there, this solved my issue...thanks
$(function () {
$('#myTab a:last').tab('show');
});
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
var target = $(e.target).attr("href");
if ((target == '#messages')) {
alert('ok');
} else {
alert('not ok');
}
});
the problem is that attr('href') is never empty.
Or to compare the #id = "#some value" and then call the ajax.
I have just compile it and it compiles fine without the implicit import, probably you're seeing a stale cache or something of your IDE.
Have you tried compiling from the command line?
I have the exact same version:
Probably you're thinking the warning is an error.
UPDATE
It looks like you have a Arrays.class
file in the directory where you're trying to compile ( probably created before ). That's why the explicit import solves the problem. Try copying your source code to a clean new directory and try again. You'll see there is no error this time. Or, clean up your working directory and remove the Arrays.class
Actually this is pretty easy since Windows Vista. Microsoft added the command FORFILES
in your case
forfiles /p c:\directory /m *.xls /c "cmd /c ssconvert @file @fname.xlsx"
the only weird thing with this command is that forfiles automatically adds double quotes around @file and @fname. but it should work anyway
If you just want to throw away the changes and revert to the last commit (the one you wanted to share):
git reset --hard HEAD~
You may want to check to make absolutely sure you want this (git log
), because you'll loose all changes.
A safer alternative is to run
git reset --soft HEAD~ # reset to the last commit
git stash # stash all the changes in the working tree
git push # push changes
git stash pop # get your changes back
string.translate with table=None works fine.
>>> name = "Barack (of Washington)"
>>> name = name.translate(None, "(){}<>")
>>> print name
Barack of Washington
You could fire an event into the quit() slot of your application even without connect(). This way, the event-loop does at least one turn and should process the events within your main()-logic:
#include <QCoreApplication>
#include <QTimer>
int main(int argc, char *argv[])
{
QCoreApplication app( argc, argv );
// do your thing, once
QTimer::singleShot( 0, &app, &QCoreApplication::quit );
return app.exec();
}
Don't forget to place CONFIG += console
in your .pro-file, or set consoleApplication: true
in your .qbs Project.CppApplication.
"o" format is different for DateTime vs DateTimeOffset :(
DateTime.UtcNow.ToString("o") -> "2016-03-09T03:30:25.1263499Z"
DateTimeOffset.UtcNow.ToString("o") -> "2016-03-09T03:30:46.7775027+00:00"
My final answer is
DateTimeOffset.UtcDateTime.ToString("o") //for DateTimeOffset type
DateTime.UtcNow.ToString("o") //for DateTime type
Judging from your example, shouldn't it be {% url myproject.login.views.login_view %}
and end of story? (replace myproject
with your actual project name)
The #define
allows you to establish a value in a header that would otherwise compile to size-greater-than-zero. Your headers should not compile to size-greater-than-zero.
// File: MyFile.h
// This header will compile to size-zero.
#define TAX_RATE 0.625
// NO: static const double TAX_RATE = 0.625;
// NO: extern const double TAX_RATE; // WHAT IS THE VALUE?
EDIT: As Neil points out in the comment to this post, the explicit definition-with-value in the header would work for C++, but not C.
Try this:
<img style="display: inline;" src="img/logo.png" alt="logo" />
<h1 style="display: inline;">My website name</h1>
ser.read(64)
should be ser.read(size=64)
; ser.read uses keyword arguments, not positional.
Also, you're reading from the port twice; what you probably want to do is this:
i=0
for modem in PortList:
for port in modem:
try:
ser = serial.Serial(port, 9600, timeout=1)
ser.close()
ser.open()
ser.write("ati")
time.sleep(3)
read_val = ser.read(size=64)
print read_val
if read_val is not '':
print port
except serial.SerialException:
continue
i+=1
docker start -a -i `docker ps -q -l`
Explanation:
docker start
start a container (requires name or ID)
-a
attach to container
-i
interactive mode
docker ps
List containers
-q
list only container IDs
-l
list only last created container
To write console output to a txt file
public static void main(String[] args) {
int i;
List<String> ls = new ArrayList<String>();
for (i = 1; i <= 100; i++) {
String str = null;
str = +i + ":- HOW TO WRITE A CONSOLE OUTPUT IN A TEXT FILE";
ls.add(str);
}
String listString = "";
for (String s : ls) {
listString += s + "\n";
}
FileWriter writer = null;
try {
writer = new FileWriter("final.txt");
writer.write(listString);
writer.close();
} catch (IOException e) {
e.printStackTrace();
}
}
If you want to generate the PDF rather then the text file, you use the dependency given below:
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>itextpdf</artifactId>
<version>5.0.6</version>
</dependency>
To generate a PDF, use this code:
public static void main(String[] args) {
int i;
List<String> ls = new ArrayList<String>();
for (i = 1; i <= 100; i++) {
String str = null;
str = +i + ":- HOW TO WRITE A CONSOLE OUTPUT IN A PDF";
ls.add(str);
}
String listString = "";
for (String s : ls) {
listString += s + "\n";
}
Document document = new Document();
try {
PdfWriter writer1 = PdfWriter
.getInstance(
document,
new FileOutputStream(
"final_pdf.pdf"));
document.open();
document.add(new Paragraph(listString));
document.close();
writer1.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (DocumentException e) {
e.printStackTrace();
}
}
If your user has a local folder e.g. Linux, in your users home folder you could create a .my.cnf file and provide the credentials to access the server there. for example:-
[client]
host=localhost
user=yourusername
password=yourpassword or exclude to force entry
database=mygotodb
Mysql would then open this file for each user account read the credentials and open the selected database.
Not sure on Windows, I upgraded from Windows because I needed the whole house not just the windows (aka Linux) a while back.
The default is Ctrl + F6. You can change it by going to Window preferences. I usually change it to Ctrl + Tab, the same we use in switching tabs in a browser and other stuff.
In short: I don't think you can, but there seems to be a workaround:.
If you take a look into the Android Resource here:
http://developer.android.com/guide/topics/resources/string-resource.html
You see than under the array section (string array, at least), the "RESOURCE REFERENCE" (as you get from an XML) does not specify a way to address the individual items. You can even try in your XML to use "@array/yourarrayhere". I know that in design time you will get the first item. But that is of no practical use if you want to use, let's say... the second, of course.
HOWEVER, there is a trick you can do. See here:
Referencing an XML string in an XML Array (Android)
You can "cheat" (not really) the array definition by addressing independent strings INSIDE the definition of the array. For example, in your strings.xml:
<string name="earth">Earth</string>
<string name="moon">Moon</string>
<string-array name="system">
<item>@string/earth</item>
<item>@string/moon</item>
</string-array>
By using this, you can use "@string/earth" and "@string/moon" normally in your "android:text" and "android:title" XML fields, and yet you won't lose the ability to use the array definition for whatever purposes you intended in the first place.
Seems to work here on my Eclipse. Why don't you try and tell us if it works? :-)
For Swift 3, Swift 4 (working with cellular and Wi-Fi):
import SystemConfiguration
public class Reachability {
class func isConnectedToNetwork() -> Bool {
var zeroAddress = sockaddr_in(sin_len: 0, sin_family: 0, sin_port: 0, sin_addr: in_addr(s_addr: 0), sin_zero: (0, 0, 0, 0, 0, 0, 0, 0))
zeroAddress.sin_len = UInt8(MemoryLayout.size(ofValue: zeroAddress))
zeroAddress.sin_family = sa_family_t(AF_INET)
let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {
$0.withMemoryRebound(to: sockaddr.self, capacity: 1) {zeroSockAddress in
SCNetworkReachabilityCreateWithAddress(nil, zeroSockAddress)
}
}
var flags: SCNetworkReachabilityFlags = SCNetworkReachabilityFlags(rawValue: 0)
if SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) == false {
return false
}
/* Only Working for WIFI
let isReachable = flags == .reachable
let needsConnection = flags == .connectionRequired
return isReachable && !needsConnection
*/
// Working for Cellular and WIFI
let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0
let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0
let ret = (isReachable && !needsConnection)
return ret
}
}
Usage:
if Reachability.isConnectedToNetwork(){
print("Internet Connection Available!")
}else{
print("Internet Connection not Available!")
}
Using the base
package:
df <- data.frame(days = c(88, 11, 2, 5, 22, 1, 222, 2), name = c("Lynn", "Tom", "Chris", "Lisa", "Kyla", "Tom", "Lynn", "Lynn"))
# Three lines
target <- c("Tom", "Lynn")
index <- df$name %in% target
df[index, ]
# One line
df[df$name %in% c("Tom", "Lynn"), ]
Output:
days name
1 88 Lynn
2 11 Tom
6 1 Tom
7 222 Lynn
8 2 Lynn
Using sqldf
:
library(sqldf)
# Two alternatives:
sqldf('SELECT *
FROM df
WHERE name = "Tom" OR name = "Lynn"')
sqldf('SELECT *
FROM df
WHERE name IN ("Tom", "Lynn")')
As far as Angular CLI: 7.1.4, there are two common ways to achieve changing the default port.
In the angular.json
, add the --port
option to serve
part and use ng serve
to start the server.
"serve": {
"builder": "@angular-devkit/build-angular:dev-server",
"options": {
"browserTarget": "demos:build",
"port": 1337
},
"configurations": {
"production": {
"browserTarget": "demos:build:production"
}
}
},
In the package.json
, add the --port
option to ng serve
and use npm start
to start the server.
"scripts": {
"ng": "ng",
"start": "ng serve --port 8000",
"build": "ng build",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e"
},
In addition to forcats::fct_infreq, mentioned by @HolgerBrandl, there is forcats::fct_rev, which reverses the factor order.
theTable <- data.frame(
Position=
c("Zoalkeeper", "Zoalkeeper", "Defense",
"Defense", "Defense", "Striker"),
Name=c("James", "Frank","Jean",
"Steve","John", "Tim"))
p1 <- ggplot(theTable, aes(x = Position)) + geom_bar()
p2 <- ggplot(theTable, aes(x = fct_infreq(Position))) + geom_bar()
p3 <- ggplot(theTable, aes(x = fct_rev(fct_infreq(Position)))) + geom_bar()
gridExtra::grid.arrange(p1, p2, p3, nrow=3)
I would use DBA_SOURCE (if you have access to it) because if the object you require is not owned by the schema under which you are logged in you will not see it.
If you need to know the functions and Procs inside the packages try something like this:
select * from all_source
where type = 'PACKAGE'
and (upper(text) like '%FUNCTION%' or upper(text) like '%PROCEDURE%')
and owner != 'SYS';
The last line prevents all the sys stuff (DBMS_ et al) from being returned. This will work in user_source if you just want your own schema stuff.
In my case whitespaces at the end of the lines of .gitignore was the cause. So watch out for whitespaces in the .gitignore!
There is supposedly a way to do it now with Ctrl + Alt + Click
but I use this extension because it has a bunch of other nice features that I use: https://marketplace.visualstudio.com/items?itemName=thomaswelen.SelectNextOccurrence
To do it the ASP.NET way:
<asp:TextBox ID="txtBox1" TextMode="Password" runat="server" />
Simple, just use .set_color
>>> barlist=plt.bar([1,2,3,4], [1,2,3,4])
>>> barlist[0].set_color('r')
>>> plt.show()
For your new question, not much harder either, just need to find the bar from your axis, an example:
>>> f=plt.figure()
>>> ax=f.add_subplot(1,1,1)
>>> ax.bar([1,2,3,4], [1,2,3,4])
<Container object of 4 artists>
>>> ax.get_children()
[<matplotlib.axis.XAxis object at 0x6529850>,
<matplotlib.axis.YAxis object at 0x78460d0>,
<matplotlib.patches.Rectangle object at 0x733cc50>,
<matplotlib.patches.Rectangle object at 0x733cdd0>,
<matplotlib.patches.Rectangle object at 0x777f290>,
<matplotlib.patches.Rectangle object at 0x777f710>,
<matplotlib.text.Text object at 0x7836450>,
<matplotlib.patches.Rectangle object at 0x7836390>,
<matplotlib.spines.Spine object at 0x6529950>,
<matplotlib.spines.Spine object at 0x69aef50>,
<matplotlib.spines.Spine object at 0x69ae310>,
<matplotlib.spines.Spine object at 0x69aea50>]
>>> ax.get_children()[2].set_color('r')
#You can also try to locate the first patches.Rectangle object
#instead of direct calling the index.
If you have a complex plot and want to identify the bars first, add those:
>>> import matplotlib
>>> childrenLS=ax.get_children()
>>> barlist=filter(lambda x: isinstance(x, matplotlib.patches.Rectangle), childrenLS)
[<matplotlib.patches.Rectangle object at 0x3103650>,
<matplotlib.patches.Rectangle object at 0x3103810>,
<matplotlib.patches.Rectangle object at 0x3129850>,
<matplotlib.patches.Rectangle object at 0x3129cd0>,
<matplotlib.patches.Rectangle object at 0x3112ad0>]
Something throws an exception of type std::bad_alloc
, indicating that you ran out of memory. This exception is propagated through until main
, where it "falls off" your program and causes the error message you see.
Since nobody here knows what "RectInvoice", "rectInvoiceVector", "vect", "im" and so on are, we cannot tell you what exactly causes the out-of-memory condition. You didn't even post your real code, because w h
looks like a syntax error.
Your execution plan should make this clear; the JOIN takes precedence, after which the results are filtered.
One way to achieve this is using a position:fixed
container for the background image and place it outside of the .jumbotron
. Make the bg
container the same height as the .jumbotron
and center the background image:
background: url('/assets/example/...jpg') no-repeat center center;
CSS
.bg {
background: url('/assets/example/bg_blueplane.jpg') no-repeat center center;
position: fixed;
width: 100%;
height: 350px; /*same height as jumbotron */
top:0;
left:0;
z-index: -1;
}
.jumbotron {
margin-bottom: 0px;
height: 350px;
color: white;
text-shadow: black 0.3em 0.3em 0.3em;
background:transparent;
}
Then use jQuery to decrease the height of the .jumbtron
as the window scrolls. Since the background image is centered in the DIV it will adjust accordingly -- creating a parallax affect.
JavaScript
var jumboHeight = $('.jumbotron').outerHeight();
function parallax(){
var scrolled = $(window).scrollTop();
$('.bg').css('height', (jumboHeight-scrolled) + 'px');
}
$(window).scroll(function(e){
parallax();
});
Demo
You can try using constructor.name
.
[].constructor.name
new RegExp().constructor.name
As with everything JavaScript, someone will eventually invariably point that this is somehow evil, so here is a link to an answer that covers this pretty well.
An alternative is to use Object.prototype.toString.call
Object.prototype.toString.call([])
Object.prototype.toString.call(/./)

As of pandas 0.20.3, use .to_pydatetime()
to convert any pandas.DateTimeIndex
instances to Python datetime.datetime
.
I spent around 6 hours on the same issue today. Inserts go at a 'regular' speed (less than 3sec per 100K) up until to 5MI (out of total 30MI) rows and then the performance sinks drastically (all the way down to 1min per 100K).
I will not list all of the things that did not work and cut straight to the meat.
I dropped a primary key on the target table (which was a GUID) and my 30MI or rows happily flowed to their destination at a constant speed of less than 3sec per 100K.
Found the solution:
It should be:
"{'Id1':'2','Id2':'2'}"
and not
"{'Id1':'2'},{'Id2':'2'}"
/**
* Use this function as jQuery "load" to disable request caching in IE
* Example: $('selector').loadWithoutCache('url', function(){ //success function callback... });

$.fn.loadWithoutCache = function (){
var elem = $(this);
var func = arguments[1];
$.ajax({

success: function(data, textStatus, XMLHttpRequest) {
elem.html(data);
if(func != undefined){

}
Here's how you can do that (quick and dirty solution. If you really need this kind of behavior, you should either reconsider your design or override all IList<T>
members and aggregate the source list):
using System;
using System.Collections.Generic;
namespace ConsoleApplication3
{
public class ModifiableList<T> : List<T>
{
private readonly IList<T> pendingAdditions = new List<T>();
private int activeEnumerators = 0;
public ModifiableList(IEnumerable<T> collection) : base(collection)
{
}
public ModifiableList()
{
}
public new void Add(T t)
{
if(activeEnumerators == 0)
base.Add(t);
else
pendingAdditions.Add(t);
}
public new IEnumerator<T> GetEnumerator()
{
++activeEnumerators;
foreach(T t in ((IList<T>)this))
yield return t;
--activeEnumerators;
AddRange(pendingAdditions);
pendingAdditions.Clear();
}
}
class Program
{
static void Main(string[] args)
{
ModifiableList<int> ints = new ModifiableList<int>(new int[] { 2, 4, 6, 8 });
foreach(int i in ints)
ints.Add(i * 2);
foreach(int i in ints)
Console.WriteLine(i * 2);
}
}
}
From your post, I understand that you cannot set the width to your li.
How about this?
ul {
border:2px solid red;
display:inline-block;
}
li {
display:inline;
padding:0 30%; /* try adjusting the side % to give a feel of center aligned.*/
}

SUMIF didn't worked for me, had to use SUMIFS.
=SUMIFS(TableAmount,TableMonth,"January")
TableAmount is the table to sum the values, TableMonth the table where we search the condition and January, of course, the condition to meet.
Hope this can help someone!
Java strings are simply an array of char. So, char c = s[0] where s is string.
I tried to do full compatible analog of javascript's encodeURIComponent for c# and after my 4 hour experiments I found this
c# CODE:
string a = "!@#$%^&*()_+ some text here ??? ??????? ????";
a = System.Web.HttpUtility.UrlEncode(a);
a = a.Replace("+", "%20");
the result is: !%40%23%24%25%5e%26*()_%2b%20some%20text%20here%20%d0%b0%d0%bb%d0%b8%20%d0%bc%d0%b0%d0%bc%d0%b5%d0%b4%d0%be%d0%b2%20%d0%b1%d0%b0%d0%ba%d1%83
After you decode It with Javascript's decodeURLComponent();
you will get this: !@#$%^&*()_+ some text here ??? ??????? ????
Thank You for attention
I just found a new trick to center a box in the middle of the screen even if you don't have fixed dimensions. Let's say you would like a box 60% width / 60% height. The way to make it centered is by creating 2 boxes: a "container" box that position left: 50% top :50%, and a "text" box inside with reverse position left: -50%; top :-50%;
It works and it's cross browser compatible.
Check out the code below, you probably get a better explanation:

Simply add these to your ggplot:
+ scale_x_continuous(expand = c(0, 0), limits = c(0, NA)) +
scale_y_continuous(expand = c(0, 0), limits = c(0, NA))
df <- data.frame(x = 1:5, y = 1:5)
p <- ggplot(df, aes(x, y)) + geom_point()
p <- p + expand_limits(x = 0, y = 0)
p # not what you are looking for
p + scale_x_continuous(expand = c(0, 0), limits = c(0,NA)) +

Lastly, take great care not to unintentionally exclude data off your chart. For example, a position = 'dodge'
could cause a bar to get left off the chart entirely (e.g. if its value is zero and you start the axis at zero), so you may not see it and may not even know it's there. I recommend plotting data in full first, inspect, then use the above tip to improve the plot's aesthetics.

The answer by Andrew Toulouse can be extended to division.
The division by integer constants is considered in details in the book "Hacker's Delight" by Henry S. Warren (ISBN 9780201914658).
The first idea for implementing division is to write the inverse value of the denominator in base two.
E.g.,
1/3 = (base-2) 0.0101 0101 0101 0101 0101 0101 0101 0101 .....
So,
a/3 = (a >> 2) + (a >> 4) + (a >> 6) + ... + (a >> 30)
for 32-bit arithmetics.
By combining the terms in an obvious manner we can reduce the number of operations:
b = (a >> 2) + (a >> 4)
b += (b >> 4)
b += (b >> 8)
b += (b >> 16)
There are more exciting ways to calculate division and remainders.
EDIT1:
If the OP means multiplication and division of arbitrary numbers, not the division by a constant number, then this thread might be of use: https://stackoverflow.com/a/12699549/1182653
EDIT2:
One of the fastest ways to divide by integer constants is to exploit the modular arithmetics and Montgomery reduction: What's the fastest way to divide an integer by 3?
Use the pandas idxmax
function. It's straightforward:
>>> import pandas
>>> import numpy as np
>>> df = pandas.DataFrame(np.random.randn(5,3),columns=['A','B','C'])
>>> df
A B C
0 1.232853 -1.979459 -0.573626
1 0.140767 0.394940 1.068890
2 0.742023 1.343977 -0.579745
3 2.125299 -0.649328 -0.211692
4 -0.187253 1.908618 -1.862934
>>> df['A'].argmax()
3
>>> df['B'].argmax()
4
>>> df['C'].argmax()
1
Alternatively you could also use numpy.argmax
, such as numpy.argmax(df['A'])
-- it provides the same thing, and appears at least as fast as idxmax
in cursory observations.
idxmax()
returns indices labels, not integers.
Index
you have to get it manually (which can be tricky now that duplicate row labels are allowed).HISTORICAL NOTES:
idxmax()
used to be called argmax()
prior to 0.11argmax
was deprecated prior to 1.0.0 and removed entirely in 1.0.0argmax
used to exist and perform the same function (though appeared to run more slowly than idxmax
).
argmax
function returned the integer position within the index of the row location of the maximum element.For example, consider this toy DataFrame
with a duplicate row label:
In [19]: dfrm
Out[19]:
A B C
a 0.143693 0.653810 0.586007
b 0.623582 0.312903 0.919076
c 0.165438 0.889809 0.000967
d 0.308245 0.787776 0.571195
e 0.870068 0.935626 0.606911
f 0.037602 0.855193 0.728495
g 0.605366 0.338105 0.696460
h 0.000000 0.090814 0.963927
i 0.688343 0.188468 0.352213
i 0.879000 0.105039 0.900260
In [20]: dfrm['A'].idxmax()
Out[20]: 'i'
In [21]: dfrm.iloc[dfrm['A'].idxmax()] # .ix instead of .iloc in older versions of pandas
Out[21]:
A B C
i 0.688343 0.188468 0.352213
i 0.879000 0.105039 0.900260
So here a naive use of idxmax
is not sufficient, whereas the old form of argmax
would correctly provide the positional location of the max row (in this case, position 9).
This is exactly one of those nasty kinds of bug-prone behaviors in dynamically typed languages that makes this sort of thing so unfortunate, and worth beating a dead horse over. If you are writing systems code and your system suddenly gets used on some data sets that are not cleaned properly before being joined, it's very easy to end up with duplicate row labels, especially string labels like a CUSIP or SEDOL identifier for financial assets. You can't easily use the type system to help you out, and you may not be able to enforce uniqueness on the index without running into unexpectedly missing data.
So you're left with hoping that your unit tests covered everything (they didn't, or more likely no one wrote any tests) -- otherwise (most likely) you're just left waiting to see if you happen to smack into this error at runtime, in which case you probably have to go drop many hours worth of work from the database you were outputting results to, bang your head against the wall in IPython trying to manually reproduce the problem, finally figuring out that it's because idxmax
can only report the label of the max row, and then being disappointed that no standard function automatically gets the positions of the max row for you, writing a buggy implementation yourself, editing the code, and praying you don't run into the problem again.
You can use an anonymous function, too:
$indexOfLastElement = count($array) - 1;
array_walk($array, function($element, $index) use ($indexOfLastElement) {
// do something
if (0 === $index) {
// first element‘s treatment
}
if ($indexOfLastElement === $index) {
// last not least
}
});
Three more things should be mentioned:
array_values
first.$element
you have to pass it by reference (&$element
).$indexOfLastElement
inside the use
construct, again by reference if needed.There is one approach that you can use in your case.
Step1: Start Activity B from Activity A
startActivity(new Intent(A.this, B.class));
Step2: If the user clicks on modify button start Activity A using the FLAG_ACTIVITY_CLEAR_TOP
.Also, pass the flag in extra.
Intent i = new Intent(B.this, A.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.putExtra("flag", "modify");
startActivity(i);
finish();
Step3: If the user clicks on Add button start Activity A using the FLAG_ACTIVITY_CLEAR_TOP
.Also, pass the flag in extra. FLAG_ACTIVITY_CLEAR_TOP
will clear all the opened activities up to the target and restart if no launch mode is defined in the target activity
Intent i = new Intent(B.this, A.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.putExtra("flag", "add");
startActivity(i);
finish();
Step4: Now onCreate()
method of the Activity A, need to retrieve that flag.
String flag = getIntent().getStringExtra("flag");
if(flag.equals("add")) {
//Write a code for add
}else {
//Write a code for modifying
}
I was struggling with the same problem. Opening the about page and calling finish();
from there wasn't closing the app instead was going to previous activity and I wanted to close the app from the about page itself.
This is the code which worked for me:
Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);
finish();
Hope this helps.
Why not to use Static Initialization Blocks
? Additional details here:
Static Initialization Blocks
import javax.crypto.*;
import java.security.*;
public class Java {
private static SecretKey key = null;
private static Cipher cipher = null;
public static void main(String[] args) throws Exception
{
Security.addProvider(new com.sun.crypto.provider.SunJCE());
KeyGenerator keyGenerator =
KeyGenerator.getInstance("DESede");
keyGenerator.init(168);
SecretKey secretKey = keyGenerator.generateKey();
cipher = Cipher.getInstance("DESede");
String clearText = "I am an Employee";
byte[] clearTextBytes = clearText.getBytes("UTF8");
cipher.init(Cipher.ENCRYPT_MODE, secretKey);
byte[] cipherBytes = cipher.doFinal(clearTextBytes);
String cipherText = new String(cipherBytes, "UTF8");
cipher.init(Cipher.DECRYPT_MODE, secretKey);
byte[] decryptedBytes = cipher.doFinal(cipherBytes);
String decryptedText = new String(decryptedBytes, "UTF8");
System.out.println("Before encryption: " + clearText);
System.out.println("After encryption: " + cipherText);
System.out.println("After decryption: " + decryptedText);
}
}
// Output
/*

After encryption: }????j6??m??Zyc????*????l#l??dV
After decryption: I am an Employee
*/
Here is a copy of code which works fine for me
import json
with open("test.json") as json_file:
json_data = json.load(json_file)
print(json_data)
with the data
{
"a": [1,3,"asdf",true],
"b": {
"Hello": "world"
}
}
you may want to wrap your json.load line with a try catch because invalid JSON will cause a stacktrace error message.
That syntax isn't valid in Oracle. You can do this:
UPDATE table1 SET table1.value = (SELECT table2.CODE
FROM table2
WHERE table1.value = table2.DESC)
WHERE table1.UPDATETYPE='blah'
AND EXISTS (SELECT table2.CODE
FROM table2
WHERE table1.value = table2.DESC);
Or you might be able to do this:
UPDATE
(SELECT table1.value as OLD, table2.CODE as NEW
FROM table1
INNER JOIN table2
ON table1.value = table2.DESC
WHERE table1.UPDATETYPE='blah'
) t
SET t.OLD = t.NEW
It depends if the inline view is considered updateable by Oracle ( To be updatable for the second statement depends on some rules listed here ).
you can also use a namedQuery named findAll for all your entities and call it in your generic FindAll with
entityManager.createNamedQuery(persistentClass.getSimpleName()+"findAll").getResultList();
If checkout master
was the last thing you did, then the reflog entry HEAD@{1}
will contain your commits (otherwise use git reflog
or git log -p
to find them). Use git merge HEAD@{1}
to fast forward them into master.
EDIT:
As noted in the comments, Git Ready has a great article on this.
git reflog
and git reflog --all
will give you the commit hashes of the mis-placed commits.

I just created a new environment with conda and things are different. My sys.path
was not correct for a bit until I figured out way.
As a result, I want to point out for anyone else confused by a change in conda
, that if you have upgraded conda and created an environment, it will now tell you (as opposed to previous behavior):
# To activate this environment, use
#
# $ conda activate test
#
# To deactivate an active environment, use
#
# $ conda deactivate
Thus, the new way to activate/deactivate environments is to do it like the above.
Indeed, if you upgrade from an older version of conda and you try the above, you may see the following helpful message (which I did):
CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If your shell is Bash or a Bourne variant, enable conda for the current user with
$ echo ". ~/anaconda/etc/profile.d/conda.sh" >> ~/.bash_profile
or, for all users, enable conda with
$ sudo ln -s ~/anaconda/etc/profile.d/conda.sh /etc/profile.d/conda.sh
The options above will permanently enable the 'conda' command, but they do NOT
put conda's base (root) environment on PATH. To do so, run
$ conda activate
in your terminal, or to put the base environment on PATH permanently, run
$ echo "conda activate" >> ~/.bash_profile
Previous to conda 4.4, the recommended way to activate conda was to modify PATH in
your ~/.bash_profile file. You should manually remove the line that looks like
export PATH="~/anaconda/bin:$PATH"
^^^ The above line should NO LONGER be in your ~/.bash_profile file! ^^^
Changing the above fixed my issues with sys.path
in activated conda environments.

UPDATE
Bootstrap 4 has spacing utilities to handle this https://getbootstrap.com/docs/4.0/utilities/spacing/
.mt-0 {
margin-top: 0 !important;
}

ORIGINAL ANSWER
If you are using SASS, this is what I normally do.
$margins: (xs: 0.5rem, sm: 1rem, md: 1.5rem, lg: 2rem, xl: 2.5rem);
@each $name, $value in $margins {
.margin-top-#{$name} {
margin-top: $value;
}
.margin-bottom-#{$name} {
margin-bottom: $value;
}
}
so you can later use margin-top-xs
for example
Use following hexadecimal code for transparent text colour: #00FFFF00
I think you meant something like "*" (star) as a wildcard for example:
or in your example: "bird*" => everything that starts with bird
I had a similar problem and wrote a function with RegExp:

rule = rule.split("*").map(escapeRegex).join(".*");_x000D_
_x000D_
// "^" => Matches any string with the following at the beginning of it_x000D_

If you want to read more about the used functions:
If you want to use names, try a namedtuple:
from collections import namedtuple
Pair = namedtuple("Pair", ["first", "second"])
pairs = [Pair("a", 1), Pair("b", 2), Pair("c", 3)]
for pair in pairs:
print("First = {}, second = {}".format(pair.first, pair.second))
I have done it by the following way
Like the following image. See for more information.
VBA is not VB/VB.NET
The correct reference to use is Do..Loop Statement (VBA). Also see the article Excel VBA For, Do While, and Do Until. One way to write this is:
Do While counter < 20
counter = counter + 1
Loop
(But a For..Next might be more appropriate here.)
Happy coding.

Yes, there are many well documented algorithms like:
A good summary ("Sam's String Metrics") can be found here (original link dead, so it links to Internet Archive)
Also check these projects:
I've done some research and it seems that the sys.argv might require an argument at the command line when running the script
Not might, but definitely requires. That's the whole point of sys.argv
, it contains the command line arguments. Like any python array, accesing non-existent element raises IndexError
.
Although the code uses try/except
to trap some errors, the offending statement occurs in the first line.
So the script needs a directory name, and you can test if there is one by looking at len(sys.argv)
and comparing to 1+number_of_requirements. The argv always contains the script name plus any user supplied parameters, usually space delimited but the user can override the space-split through quoting. If the user does not supply the argument, your choices are supplying a default, prompting the user, or printing an exit error message.
To print an error and exit when the argument is missing, add this line before the first use of sys.argv:
if len(sys.argv)<2:
print "Fatal: You forgot to include the directory name on the command line."
print "Usage: python %s <directoryname>" % sys.argv[0]
sys.exit(1)
sys.argv[0]
always contains the script name, and user inputs are placed in subsequent slots 1, 2, ...

Using url.format:
var url = require('url');
This support all protocols and include port number. If you don't have a query string in your originalUrl you can use this cleaner solution:
var requrl = url.format({
protocol: req.protocol,
host: req.get('host'),
pathname: req.originalUrl,
});
If you have a query string:
var urlobj = url.parse(req.originalUrl);
urlobj.protocol = req.protocol;
urlobj.host = req.get('host');
var requrl = url.format(urlobj);
"FetchType.LAZY
" will only fire for primary table. If in your code you call any other method that has a parent table dependency then it will fire query to get that table information. (FIRES MULTIPLE SELECT)
"FetchType.EAGER
" will create join of all table including relevant parent tables directly. (USES JOIN
)
When to Use:
Suppose you compulsorily need to use dependant parent table informartion then choose FetchType.EAGER
.
If you only need information for certain records then use FetchType.LAZY
.
Remember, FetchType.LAZY
needs an active db session factory at the place in your code where if you choose to retrieve parent table information.
E.g. for LAZY
:
.. Place fetched from db from your dao loayer
.. only place table information retrieved
.. some code
.. getCity() method called... Here db request will be fired to get city table info
I agree with Kevin he has the best answer but sometimes when you have different keys in your local storage with the same values for example you want your public users to see how many times they have added their items into their baskets you need to show them the number of times as well then you ca use this:
var set = localStorage.setItem('key', 'value');
var element = document.getElementById('tagId');
for ( var i = 0, len = localStorage.length; i < len; ++i ) {
element.innerHTML = localStorage.getItem(localStorage.key(i)) + localStorage.key(i).length;
}
The problem may be that ssh is trying to connect to all the different IPs that www.google.com
resolves to. For example on my machine:

debug1: Connecting to www.google.com [173.194.43.20] port 22.

As noted by others, after some years an 'out-of-core' pandas equivalent has emerged: dask. Though dask is not a drop-in replacement of pandas and all of its functionality it stands out for several reasons:
Dask is a flexible parallel computing library for analytic computing that is optimized for dynamic task scheduling for interactive computational workloads of “Big Data” collections like parallel arrays, dataframes, and lists that extend common interfaces like NumPy, Pandas, or Python iterators to larger-than-memory or distributed environments and scales from laptops to clusters.
Dask emphasizes the following virtues:
- Familiar: Provides parallelized NumPy array and Pandas DataFrame objects
- Flexible: Provides a task scheduling interface for more custom workloads and integration with other projects.
- Native: Enables distributed computing in Pure Python with access to the PyData stack.
- Fast: Operates with low overhead, low latency, and minimal serialization necessary for fast numerical algorithms
- Scales up: Runs resiliently on clusters with 1000s of cores Scales down: Trivial to set up and run on a laptop in a single process
- Responsive: Designed with interactive computing in mind it provides rapid feedback and diagnostics to aid humans
and to add a simple code sample:
import dask.dataframe as dd
df = dd.read_csv('2015-*-*.csv')
df.groupby(df.user_id).value.mean().compute()
replaces some pandas code like this:
import pandas as pd
df = pd.read_csv('2015-01-01.csv')
df.groupby(df.user_id).value.mean()
and, especially noteworthy, provides through the concurrent.futures
interface a general infrastructure for the submission of custom tasks:
from dask.distributed import Client
client = Client('scheduler:port')
futures = []
for fn in filenames:
future = client.submit(load, fn)
futures.append(future)
summary = client.submit(summarize, futures)
summary.result()
for (Iterator<String> itr = someList.iterator(); itr.hasNext(); ) {
String item = itr.next();
System.out.println(item);
}
You can convert char to int and viceversa easily because for the machine an int and a char are the same, 8 bits, the only difference comes when they have to be shown in screen, if the number is 65 and is saved as a char, then it will show 'A', if it's saved as a int it will show 65.
With other types things change, because they are stored differently in memory. There's standard function in C that allows you to convert from string to double easily, it's atof. (You need to include stdlib.h)
#include <stdlib.h>
int main()
{
string word;
openfile >> word;
double lol = atof(word.c_str()); /*c_str is needed to convert string to const char*
previously (the function requires it)*/
return 0;
}
Using old C++ version, you can use this snippet :
template<typename T>
string toBinary(const T& t)
{
string s = "";
int n = sizeof(T)*8;
for(int i=n-1; i>=0; i--)
{
s += (t & (1 << i))?"1":"0";

If you have a primary key or a unique key/index, the faster method possible (Tested with 4 millions row tables)
SHOW INDEXES FROM "database.tablename" WHERE Key_Name=\"PRIMARY\"
and then get cardinality field (it is close to instant)
Times where from 0.4s to 0.0001ms
You could also just run
go build
in your project folder myproject/go/src/myprog
Then you can just type
./myprog
to run your app
I had a similar problem. But the problem was in the file name '.htaccess', because the Windows doesn't let the file's name begin with a ".", the solution was rename the file with a CMD command. "rename c:\xampp\htdocs\htaccess.txt .htaccess"
I've solved a similar issue by putting all of my main content within an extra div tag (id="outer"). I've then moved the div tag with id="footer" outside of this last "outer" div tag. I've used CSS to specify the height of "outer" and specified the width and height of "footer". I've also used CSS to specify the margin-left and margin-right of "footer" as auto. The result is that the footer sits firmly at the bottom of my page and scrolls with the page too (although, it's still appears inside the "outer" div, but happily outside of the main "content" div. which seems strange, but it's where I want it).
Content-Type: application/json
is just the content header. The content header is just information about the type of returned data, ex::JSON,image(png,jpg,etc..),html.
Keep in mind, that JSON in JavaScript is an array or object. If you want to see all the data, use console.log instead of alert:
alert(response.text); // Will alert "[object Object]" string
console.log(response.text); // Will log all data objects
If you want to alert the original JSON content as a string, then add single quotation marks ('):
echo "'" . json_encode(array('text' => 'omrele')) . "'";
// alert(response.text) will alert {"text":"omrele"}
Do not use double quotes. It will confuse JavaScript, because JSON uses double quotes on each value and key:
echo '<script>var returndata=';
echo '"' . json_encode(array('text' => 'omrele')) . '"';
echo ';</script>';
// It will return the wrong JavaScript code:
<script>var returndata="{"text":"omrele"}";</script>
This will work in SQL Server:
ALTER TABLE Employee ADD CONSTRAINT DF_SomeName DEFAULT N'SANDNES' FOR CityBorn;
Tested with below sample snippet, tried with MapUtils, and Java8 Stream feature. It worked with both cases.
public static void main(String[] args) {
Map<String, String> test = new HashMap<String, String>();
test.put("a", "1");
test.put("d", "1");
test.put("b", "2");
test.put("c", "3");
test.put("d", "4");
test.put("d", "41");
System.out.println(test);
Map<String, String> test1 = MapUtils.invertMap(test);
System.out.println(test1);
Map<String, String> mapInversed =
test.entrySet()
.stream()
.collect(Collectors.toMap(Map.Entry::getValue, Map.Entry::getKey));
System.out.println(mapInversed);
}
Output:
{a=1, b=2, c=3, d=41}
{1=a, 2=b, 3=c, 41=d}
{1=a, 2=b, 3=c, 41=d}
You can use React.PropTypes.shape()
as an argument to React.PropTypes.arrayOf()
:
// an array of a particular shape.
ReactComponent.propTypes = {
arrayWithShape: React.PropTypes.arrayOf(React.PropTypes.shape({
color: React.PropTypes.string.isRequired,
fontSize: React.PropTypes.number.isRequired,
})).isRequired,
}
See the Prop Validation section of the documentation.
UPDATE
As of react v15.5
, using React.PropTypes
is deprecated and the standalone package prop-types
should be used instead :
// an array of a particular shape.
import PropTypes from 'prop-types'; // ES6
var PropTypes = require('prop-types'); // ES5 with npm
ReactComponent.propTypes = {
arrayWithShape: PropTypes.arrayOf(PropTypes.shape({
color: PropTypes.string.isRequired,
fontSize: PropTypes.number.isRequired,
})).isRequired,
}
As per the docs, OkHttp version 3 replaced FormEncodingBuilder
with FormBody
and FormBody.Builder()
, so the old examples won't work anymore.
Form and Multipart bodies are now modeled. We've replaced the opaque
FormEncodingBuilder
with the more powerfulFormBody
andFormBody.Builder
combo.Similarly we've upgraded
MultipartBuilder
intoMultipartBody
,MultipartBody.Part
, andMultipartBody.Builder
.
So if you're using OkHttp 3.x try the following example:
OkHttpClient client = new OkHttpClient();
RequestBody formBody = new FormBody.Builder()
.add("message", "Your message")
.build();
Request request = new Request.Builder()
.url("http://www.foo.bar/index.php")
.post(formBody)
.build();
try {
Response response = client.newCall(request).execute();
// Do something with the response.
} catch (IOException e) {
e.printStackTrace();
}
Looks like you're trying to execute a windows file (.exe) Surely you ought to be using powershell. Anyway on a Linux bash shell a simple one-liner will suffice.
[/home/$] for filename in /Data/*.txt; do for i in {0..3}; do ./MyProgam.exe Data/filenameLogs/$filename_log$i.txt; done done
Or in a bash
#!/bin/bash
for filename in /Data/*.txt;
do
for i in {0..3};
do ./MyProgam.exe Data/filename.txt Logs/$filename_log$i.txt;
done
done
Notice that there is a difference between
set encoding
and
set fileencoding
In the first case, you'll change the output encoding that is shown in the terminal. In the second case, you'll change the output encoding of the file that is written.
Here is a simple approach:
#!/bin/bash
USE_IP='-o StrictHostKeyChecking=no [email protected]'
FILE_NAME=/home/user/file.txt
SSH_PASS='sshpass -p password-for-remote-machine'
if $SSH_PASS ssh $USE_IP stat $FILE_NAME \> /dev/null 2\>\&1
then
echo "File exists"
else
echo "File does not exist"
fi
You need to install sshpass on your machine to work it.
An "em" is a typographical unit of width, the width of a wide-ish letter like "m" pronounced "em". Similarly there is an "en". Similarly "en-dash" and "em-dash" for – and —
ArrayList
is newer and 20-30% faster.
If you don't need something explitly apparent in Vector
, use ArrayList
ALTER TABLE `{$installer->getTable('sales/quote_payment')}`
ADD `custom_field_one` VARCHAR( 255 ) NOT NULL,
ADD `custom_field_two` VARCHAR( 255 ) NOT NULL;
Add backtick i.e. " ` " properly. Write your getTable name and column name between backtick.
Doing this inline, I set the margin to 0 (ul style="margin:-0px"). The bullets align with paragraph with no overhang.

Try to change #include <gl/glut.h>

I Had the same problem, and it was because the simulator somehow got in airplane mode, once this was disabled my App worked fine :-) I had tried everything, rebuild, clean+build and reboot android studio and reboot the computer, even reinstalling android studio..
To avoid ZoneId you can do:
LocalDateTime date = LocalDateTime.of(1970, 1, 1, 0, 0);
System.out.println("Initial Epoch (TimeInMillis): " + date.toInstant(ZoneOffset.ofTotalSeconds(0)).toEpochMilli());
Getting 0 as value, that's right!
If you want to the batch program to exit back to the prompt and not close the prompt (A.K.A cmd.exe) you can use "exit /b".
This may help.
set /p _sure="Are you sure?"
::The underscore is used to ensure that "sure" is not an enviroment
::varible
if /I NOT "_sure"=="y" (
::the /I makes it so you can
exit /b
) else (
::Any other modifications...
)
Or if you don't want to use as many lines...
Set /p _sure="Are you sure?"
if /I NOT "_sure"=="y" exit /b
::Any other modifications and commands.
Hope this helps...
All above not worked for me, but this was: Check that the name of Root element of class is exactly like the one from XML case sensitive.
you can use strbuilder.insert(0,i);
Try a different protocol. git:// may have problems from your firewall, for example; try a git clone with https: instead.

You can also accomplish this using the sqldf
package as shown below:
library(sqldf)
x <- read.table(text='Name Month Rate1 Rate2
Aira 1 12 23
Aira 2 18 73
Aira 3 19 45
Ben 1 53 19
Ben 2 22 87
Ben 3 19 45
Cat 1 22 87
Cat 2 67 43
Cat 3 45 32', header=TRUE)
sqldf("
select
Name
,avg(Rate1) as Rate1_float
,avg(Rate2) as Rate2_float
,avg(Rate1) as Rate1
,avg(Rate2) as Rate2
from x
group by
Name
")
# Name Rate1_float Rate2_float Rate1 Rate2
#1 Aira 16.33333 47.00000 16 47
#2 Ben 31.33333 50.33333 31 50
#3 Cat 44.66667 54.00000 44 54
I am a recent convert to dplyr
as shown in other answers, but sqldf
is nice as most data analysts/data scientists/developers have at least some fluency in SQL. In this way, I think it tends to make for more universally readable code than dplyr
or other solutions presented above.
UPDATE: In responding to the comment below, I attempted to update the code as shown above. However, the behavior was not as I expected. It seems that the column definition (i.e. int
vs float
) is only carried through when the column alias matches the original column name. When you specify a new name, the aggregate column is returned without rounding.
you can do it better with two datagridview, you add the same datasource , hide the headers of the second, set the height of the second = to the height of the rows of the first, turn off all resizable atributes of the second, synchronize the scrollbars of both, only horizontal, put the second on the botton of the first etc.
take a look:
dgv3.ColumnHeadersVisible = false;
dgv3.Height = dgv1.Rows[0].Height;
dgv3.Location = new Point(Xdgvx, this.dgv1.Height - dgv3.Height - SystemInformation.HorizontalScrollBarHeight);
dgv3.Width = dgv1.Width;
private void dgv1_Scroll(object sender, ScrollEventArgs e)
{
if (e.ScrollOrientation == ScrollOrientation.HorizontalScroll)
{
dgv3.HorizontalScrollingOffset = e.NewValue;
}
}
Get all views of a view plus its children recursively in Kotlin:
private fun View.getAllViews(): List<View> {
if (this !is ViewGroup || childCount == 0) return listOf(this)
return children
.toList()
.flatMap { it.getAllViews() }
.plus(this as View)
}
I think this Library of JavaScript might Help you:
It's called Print.js
First Include
<script src="print.js"></script>
<link rel="stylesheet" type="text/css" href="print.css">
It's basic usage is to call printJS()
and just pass in a PDF document url: printJS('docs/PrintJS.pdf')
What I did was something like this, this will also show "Loading...." if PDF document is too large.
<button type="button" onclick="printJS({printable:'docs/xx_large_printjs.pdf', type:'pdf', showModal:true})">
Print PDF with Message
</button>
However keep in mind that:
Firefox currently doesn't allow printing PDF documents using iframes. There is an open bug in Mozilla's website about this. When using Firefox, Print.js will open the PDF file into a new tab.
Despite its miles-away-from-being-pretty interface, JSPretty is a good, free and online tool for making javascript source codes human-readable. You can enforce your preferred type of indentation and it can also detect obfuscation.
This works for dates that currently have the same UTC offset as SQL Server's host; it doesn't account for daylight savings changes. Replace YOUR_DATE
with the local date to convert.
SELECT DATEADD(second, DATEDIFF(second, GETDATE(), GETUTCDATE()), YOUR_DATE);
A good solution and without "contraptions" is the forgotten ZStack

Nothing to do
javac
is the Java compiler. java
is the JVM and what you use to execute a Java program. You do not execute .java
files, they are just source files.
Presumably there is .jar
somewhere (or a directory containing .class
files) that is the product of building it in Eclipse:
java/src/com/mypackage/Main.java java/classes/com/mypackage/Main.class java/lib/mypackage.jar
From directory java
execute:
java -cp lib/mypackage.jar Main arg1 arg2
I don't exactly understand what's the problem. Incomplete type is not the type that's "missing". Incompete type is a type that is declared but not defined (in case of struct types). To find the non-defining declaration is easy. As for the finding the missing definition... the compiler won't help you here, since that is what caused the error in the first place.
A major reason for incomplete type errors in C are typos in type names, which prevent the compiler from matching one name to the other (like in matching the declaration to the definition). But again, the compiler cannot help you here. Compiler don't make guesses about typos.
num = list(str(100))
index = len(num)

This can be done with three commands:
curl -u 'nyeates' https://api.github.com/user/repos -d '{"name":"projectname","description":"This project is a test"}'
git remote add origin [email protected]:nyeates/projectname.git
git push origin master
(updated for v3 Github API)
curl -u 'nyeates' https://api.github.com/user/repos -d '{"name":"projectname","description":"This project is a test"}'
git remote add origin [email protected]:nyeates/projectname.git
git push origin master
So you want to take latitude/longitude coordinates and find out the pixel coordinates on your image of that location?
The main GMap2 class provides transformation to/from a pixel on the displayed map and a lat/long coordinate:
Gmap2.fromLatLngToContainerPixel(latlng)
For example:
var gmap2 = new GMap2(document.getElementById("map_canvas"));
var geocoder = new GClientGeocoder();
geocoder.getLatLng( "1600 Pennsylvania Avenue NW Washington, D.C. 20500",
function( latlng ) {
var pixel_coords = gmap2.fromLatLngToContainerPixel(latlng);
window.alert( "The White House is at pixel coordinates (" +
pixel_coodrs.x + ", " + pixel_coords.y + ") on the " +
"map image shown on this page." );
}
);
So assuming that your map image is a screen grab of the Google Map display, then this will give you the correct pixel coordinate on that image of a lat/long coordinate.
Things are trickier if you're grabbing tile images and stitching them together yourself since the area of the complete tile set will lie outside the area of the displayed map.
In this case, you'll need to use the left and top values of the top-left image tile as an offset from the coordinates that fromLatLngToContainerPixel(latlng:GLatLng) gives you, subtracting the left coordinate from the x coordinate and top from the y coordinate. So if the top-left image is positioned at (-50, -122) (left, top), and fromLatLngToContainerPixel() tells you a lat/long is at pixel coordinate (150, 320), then on the image stitched together from tiles, the true position of the coordinate is at (150 - (-50), 320 - (-122)) which is (200, 442).
It's also possible that a similar GMap2 coordinate translation function:
GMap2.fromLatLngToDivPixel(latlng:GLatLng)
will give you the correct lat/long to pixel translation for the stitched-tiles case - I've not tested this, nor is it 100% clear from the API docs.
See here for more: http://code.google.com/apis/maps/documentation/reference.html#GMap2.Methods.Coordinate-Transformations
The only way I was able to get C# Express 2008 to work was to move the database file. So, I opened up SQL Server Management Studio and after dropping the database, I copied the file to my project folder. Then I reattached the database to management studio. Now, when I try to attach to the local copy it works. Apparently, you can not use the same database file more than once.
It is possible to get a context from within a Fragment
Just do
public class YourFragment extends Fragment {
public View onCreateView(@NonNull LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
final View root = inflater.inflate(R.layout.yout_fragment_layout, container, false);
// get context here
Context context = getContext();
// do as you please with the context
// if you decide to go with second option
SomeViewModel someViewModel = ViewModelProviders.of(this).get(SomeViewModel.class);
Context context = homeViewModel.getContext();
// do as you please with the context
return root;
}
}
You may also attached an AndroidViewModel
in the onCreateView
method that implements a method that returns the application context
public class SomeViewModel extends AndroidViewModel {
private MutableLiveData<ArrayList<String>> someMutableData;
Context context;
public SomeViewModel(Application application) {
super(application);
context = getApplication().getApplicationContext();
someMutableData = new MutableLiveData<>();
.
.
}
public Context getContext() {
return context
}
}
If you are allowed to use "==" as seems to be the case, you can do something like that taking advantage of the fact that an exception will be raised if an array index is out of bounds. The code is for double, but you can cast any numeric type to a double (here the eventual loss of precision would not be important at all).
I have added comments to explain the process (bring the value in ]-2.0; -1.0] union [1.0; 2.0[) and a small test driver as well.
class T {
public static boolean positive(double f)
{
final boolean pos0[] = {true};
final boolean posn[] = {false, true};
if (f == 0.0)
return true;
while (true) {
// If f is in ]-1.0; 1.0[, multiply it by 2 and restart.
try {
if (pos0[(int) f]) {
f *= 2.0;
continue;
}
} catch (Exception e) {
}
// If f is in ]-2.0; -1.0] U [1.0; 2.0[, return the proper answer.
try {
return posn[(int) ((f+1.5)/2)];
} catch (Exception e) {
}
// f is outside ]-2.0; 2.0[, divide by 2 and restart.
f /= 2.0;
}
}
static void check(double f)
{
System.out.println(f + " -> " + positive(f));
}
public static void main(String args[])
{
for (double i = -10.0; i <= 10.0; i++)
check(i);
check(-1e24);
check(-1e-24);
check(1e-24);
check(1e24);
}
The output is:
-10.0 -> false
-9.0 -> false
-8.0 -> false
-7.0 -> false
-6.0 -> false
-5.0 -> false

list.pop()
removes and returns the last element of the list.
I have been trying to achieve this by using 1 row single entry but I ended that Invoke command did not worked successfully because it is killing the process immediately after starting despite it can work if you are entering the session and waiting enough before exiting.
The only working way I could find, for example, to run a command with arguments and space on the remote machine HFVMACHINE1 (running Windows 7) is the following:
([WMICLASS]"\\HFVMACHINE1\ROOT\CIMV2:win32_process").Create('c:\Program Files (x86)\Thinware\vBackup\vBackup.exe -v HFSVR12-WWW')
Yes basically this is what virtualenv do , and this is what the activate
command is for, from the doc here:
activate script
In a newly created virtualenv there will be a bin/activate shell script, or a Scripts/activate.bat batch file on Windows.
This will change your $PATH to point to the virtualenv bin/ directory. Unlike workingenv, this is all it does; it's a convenience. But if you use the complete path like /path/to/env/bin/python script.py you do not need to activate the environment first. You have to use source because it changes the environment in-place. After activating an environment you can use the function deactivate to undo the changes.
The activate script will also modify your shell prompt to indicate which environment is currently active.
so you should just use activate
command which will do all that for you:
> \path\to\env\bin\activate.bat
As Sven mentioned, x[[[0],[2]],[1,3]]
will give back the 0 and 2 rows that match with the 1 and 3 columns while x[[0,2],[1,3]]
will return the values x[0,1] and x[2,3] in an array.
There is a helpful function for doing the first example I gave, numpy.ix_
. You can do the same thing as my first example with x[numpy.ix_([0,2],[1,3])]
. This can save you from having to enter in all of those extra brackets.

New in the most recent version of Visual Studio, there is View --> Terminal, which will open a PowerShell instance as a VS dockable window, rather than a floating PowerShell or cmd instance from the Developer Command Prompt.
Set theory is inappropriate for lists since duplicates will result in wrong answers using set theory.
For example:
a = [1, 3, 3, 3, 5]
b = [1, 3, 3, 4, 5]
set(b) > set(a)
has no meaning. Yes, it gives a false answer but this is not correct since set theory is just comparing: 1,3,5 versus 1,3,4,5. You must include all duplicates.
Instead you must count each occurrence of each item and do a greater than equal to check. This is not very expensive, because it is not using O(N^2) operations and does not require quick sort.
#!/usr/bin/env python
from collections import Counter
def containedInFirst(a, b):
a_count = Counter(a)
b_count = Counter(b)
for key in b_count:
if a_count.has_key(key) == False:
return False
if b_count[key] > a_count[key]:
return False
return True
a = [1, 3, 3, 3, 5]
b = [1, 3, 3, 4, 5]
print "b in a: ", containedInFirst(a, b)
a = [1, 3, 3, 3, 4, 4, 5]
b = [1, 3, 3, 4, 5]
print "b in a: ", containedInFirst(a, b)
Then running this you get:
$ python contained.py
b in a: False
b in a: True
Maybe .text
instead of .html
?

Using refs
is not best practice because it reads the DOM directly, it's better to use React's state
instead. Also, your button doesn't change because the component is not re-rendered and stays in its initial state.
You can use setState
together with an onChange
event listener to render the component again every time the input field changes:
// Input field listens to change, updates React's state and re-renders the component.
<input onChange={e => this.setState({ value: e.target.value })} value={this.state.value} />
// Button is disabled when input state is empty.
<button disabled={!this.state.value} />
Here's a working example:
class AddItem extends React.Component {_x000D_
constructor() {_x000D_
super();_x000D_
this.state = { value: '' };_x000D_
this.onChange = this.onChange.bind(this);_x000D_
this.add = this.add.bind(this);_x000D_
}_x000D_
_x000D_

Look at my code, but be aware. I use async/await, because latest Chrome beta can read any es6 code, which gets by TypeScript with compilation. So, you must replace asyns/await by .then()
.
Input change handler:
/**
* @param fileInput
*/
public psdTemplateSelectionHandler (fileInput: any){
let FileList: FileList = fileInput.target.files;
for (let i = 0, length = FileList.length; i < length; i++) {
this.psdTemplates.push(FileList.item(i));
}
this.progressBarVisibility = true;
}
Submit handler:
public async psdTemplateUploadHandler (): Promise<any> {
let result: any;
if (!this.psdTemplates.length) {
return;
}
this.isSubmitted = true;
this.fileUploadService.getObserver()
.subscribe(progress => {
this.uploadProgress = progress;
});
try {
result = await this.fileUploadService.upload(this.uploadRoute, this.psdTemplates);
} catch (error) {
document.write(error)
}
if (!result['images']) {
return;
}
this.saveUploadedTemplatesData(result['images']);
this.redirectService.redirect(this.redirectRoute);
}
FileUploadService. That service also stored uploading progress in progress$ property, and in other places, you can subscribe on it and get new value every 500ms.

}
};
FileUploadService.setUploadUpdateInterval(500);
xhr.upload.onprogress = (event) => {
this.progress = Math.round(event.loaded / event.total * 100);
this.progressObserver.next(this.progress);
};
xhr.open('POST', url, true);
xhr.send(formData);
});
}

You can use this code to see the last modified date of a file.
DateTime dt = File.GetLastWriteTime(path);
And this code to see the creation time.
DateTime fileCreatedDate = File.GetCreationTime(@"C:\Example\MyTest.txt");
Have you tried HttpServerUtility.UrlDecode
or HttpUtility.UrlDecode
?
Here is a TypeScript version of @meseern's answer that avoids unnecessary assignments on re-render:
import React, { useState, useEffect } from 'react';
export function useContainerDimensions(myRef: React.RefObject<any>) {
const [dimensions, setDimensions] = useState({ width: 0, height: 0 });
useEffect(() => {
const getDimensions = () => ({
width: (myRef && myRef.current.offsetWidth) || 0,
height: (myRef && myRef.current.offsetHeight) || 0,
});
const handleResize = () => {
setDimensions(getDimensions());
};
if (myRef.current) {
setDimensions(getDimensions());
}
window.addEventListener('resize', handleResize);
return () => {
window.removeEventListener('resize', handleResize);
};
}, [myRef]);
return dimensions;
}
I had the same problem and got it solved by using a different directory.

You need use JSON.parse() for convert String into a Object:
var obj = JSON.parse('{ "firstName":"name1", "lastName": "last1" }');
Another simple solution is to create a filter:
app.filter('trusted', ['$sce', function ($sce) {
return function(url) {
return $sce.trustAsResourceUrl(url);
};
}]);
Then specify the filter in ng-src
:
<video controls poster="img/poster.png">
<source ng-src="{{object.src | trusted}}" type="video/mp4"/>
</video>
Even if the question is old but i will share the solution that answers perfectly the question :
SET SERVEROUTPUT ON;
DECLARE
RC SYS_REFCURSOR;
Result1 varchar2(25);
Result2 varchar2(25);
BEGIN
OPEN RC FOR SELECT foo, bar into Result1, Result2 FROM foobar;
DBMS_SQL.RETURN_RESULT(RC);
END;
Here you have not specified class name to be imported from Map.js file. If Map is class exportable class name exist in the Map.js file, your code should be as follow.
import React, { Component } from 'react';
import Map from './Map';
class App extends Component {
render() {
return (
<div className="App">
<Map/>
</div>
);
}
}
export default App;
Since react-router v5.1 with hooks:
import { useParams } from 'react-router';
export default function DetailsPage() {
const { id } = useParams();
}
You could also look at git-svn, which is essentially a git front-end to subversion.
Message queues are ideal for requests which may take a long time to process. Requests are queued and can be processed offline without blocking the client. If the client needs to be notified of completion, you can provide a way for the client to periodically check the status of the request.
Message queues also allow you to scale better across time. It improves your ability to handle bursts of heavy activity, because the actual processing can be distributed across time.
Note that message queues and web services are orthogonal concepts, i.e. they are not mutually exclusive. E.g. you can have a XML based web service which acts as an interface to a message queue. I think the distinction your looking for is Message Queues versus Request/Response, the latter is when the request is processed synchronously.
you can use the return
statement without any parameter to exit a function
def foo(element):
do something
if check is true:
do more (because check was succesful)
else:
return
do much much more...
or raise an exception if you want to be informed of the problem
def foo(element):
do something
if check is true:
do more (because check was succesful)
else:
raise Exception("cause of the problem")
do much much more...
The format
method was introduced in Python 2.6. It is more capable and not much more difficult to use:
>>> "Hello {}, my name is {}".format('john', 'mike')
'Hello john, my name is mike'.
>>> "{1}, {0}".format('world', 'Hello')
'Hello, world'
>>> "{greeting}, {}".format('world', greeting='Hello')
'Hello, world'
>>> '%s' % name
"{'s1': 'hello', 's2': 'sibal'}"
>>> '%s' %name['s1']
'hello'
It occurred because you tried to create a foreign key from tblDomare.PersNR
to tblBana.BanNR
but/and the values in tblDomare.PersNR
didn't match with any of the values in tblBana.BanNR
. You cannot create a relation which violates referential integrity.
Here is a performance comparison of the proposed methods in other answers.
> foo <- sapply(letters, function(x){runif(5)}, simplify = FALSE)
> microbenchmark::microbenchmark('k' %in% names(foo),
is.null(foo[['k']]),
exists('k', where = foo))
Unit: nanoseconds
expr min lq mean median uq max neval cld
"k" %in% names(foo) 467 933 1064.31 934 934 10730 100 a
is.null(foo[["k"]]) 0 0 168.50 1 467 3266 100 a
exists("k", where = foo) 6532 6998 7940.78 7232 7465 56917 100 b
If you are planing to use the list as a fast dictionary accessed many times, then the is.null
approach might be the only viable option. I assume it is O(1), while the %in%
approach is O(n)?
Try this sed
version:
ls -l | sed '2 ! d'
It says "delete all the lines that aren't the second one".
The del
statement might be of use, but IIRC it isn't guaranteed to free the memory. The docs are here ... and a why it isn't released is here.
I have heard people on Linux and Unix-type systems forking a python process to do some work, getting results and then killing it.
This article has notes on the Python garbage collector, but I think lack of memory control is the downside to managed memory
If you're using #
as an operator, consider defining a new operator for it:
\newcommand{\pound}{\operatornamewithlimits{\#}}
You can then write things like \pound_{n = 1}^N
and get:
var url = window.location.pathname;
var id = url.substring(url.lastIndexOf('/') + 1);
There are three major categories of cloud service models:
Software as a service (SaaS)
SaaS is a software that is centrally hosted and managed for the end customer. It's usually based on a multi-tenant architecture (a single version of the application is used for all customers) and typically is licensed through a monthly or annual subscription.
Example Office 365, Dropbox, Dynamics CRM Online are perfect examples of SaaS software, subscribers pay a monthly or annual subscription fee, and they get Exchange as a Service (online and/or desktop Outlook) or Storage as a Service (OneDrive and Dropbox).
Platform as a service (PaaS)
With PaaS, you deploy your application into an application-hosting environment (designed for building, testing, and deploying software applications) provided by the cloud service vendor. Developers have multiple ways to deploy their applications without knowing anything about what's happening in the background to supporting it.
Example Web Apps feature in Azure App Service and Azure Cloud Services (web and worker roles) are an example of PaaS.
Infrastructure as a service (IaaS)
An IaaS cloud vendor runs and manages server farms running virtualization software, enabling you to create VMs (running Windows or Linux) that run on the vendor’s infrastructure and install anything you want on it. Developers don’t have control over the hardware or virtualization software, but they have control over almost everything else. In fact, unlike PaaS, you are completely responsible for it.

Yes,that is called short-circuiting.
Please take a look at this wikipedia page on short-circuiting
To answer the question without reading too much else into it i would
char str[2] = "\0"; /* gives {\0, \0} */
str[0] = fgetc(fp);
You could use the second line in a loop with what ever other string operations you want to keep using char's as strings.
use <sys/time.h>

gettimeofday(&tp, NULL);
long int ms = tp.tv_sec * 1000 + tp.tv_usec / 1000;

This explains the whole thing:
The HTTP Content-Security-Policy (CSP) upgrade-insecure-requests directive instructs user agents to treat all of a site's insecure URLs (those served over HTTP) as though they have been replaced with secure URLs (those served over HTTPS). This directive is intended for web sites with large numbers of insecure legacy URLs that need to be rewritten.
The upgrade-insecure-requests directive is evaluated before block-all-mixed-content and if it is set, the latter is effectively a no-op. It is recommended to set one directive or the other, but not both.
The upgrade-insecure-requests directive will not ensure that users visiting your site via links on third-party sites will be upgraded to HTTPS for the top-level navigation and thus does not replace the Strict-Transport-Security (HSTS) header, which should still be set with an appropriate max-age to ensure that users are not subject to SSL stripping attacks.
Need to include jquery-ui too:
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
With PostgreSQL 9.5, this is now native functionality (like MySQL has had for several years):
INSERT ... ON CONFLICT DO NOTHING/UPDATE ("UPSERT")
9.5 brings support for "UPSERT" operations. INSERT is extended to accept an ON CONFLICT DO UPDATE/IGNORE clause. This clause specifies an alternative action to take in the event of a would-be duplicate violation.
...
Further example of new syntax:
INSERT INTO user_logins (username, logins)
VALUES ('Naomi',1),('James',1)
ON CONFLICT (username)
DO UPDATE SET logins = user_logins.logins + EXCLUDED.logins;
I have discovered that NotePad++ now also creates a subfolder at the file location, called nppBackup. So if your file lived in a folder called c:/thisfolder have a look to see if there's a folder called c:/thisfolder/nppBackup.
Occasionally I couldn't find the backup in AppData\Roaming\Notepad++\backup, but I found it in nppBackup.
While it is true that exporting an excel file that contains special characters to csv can be a pain in the ass, there is however a simple work around: simply copy/paste the cells into a google docs and then save from there.
The validate_required function seems to expect an HTML form control (e.g, text input field) as first argument, and check whether there is a value there at all. That is not what you want in this case.
Also, when you write ['password'].value
, you create a new array of length one, containing the string
'password'
, and then read the non-existing property "value"
from it, yielding the undefined value.
What you may want to try instead is:
if (password.value != cpassword.value) { cpassword.focus(); return false; }
(You also need to write the error message somehow, but I can't see from your code how that is done.).
.user is the user settings, and I think .suo is the solution user options. You don't want these files under source control; they will be re-created for each user.
When you are dealing with objects, you want to ignore simple id's as much as convenient.
If you change the click line to this, I think you will be well on your way:
<li class="tutorial_title {{tutorial.active}}" ng-click="loadFromMenu(tutorial)" ng-repeat="tutorial in section.tutorials">
Also, I think you may need to change
class="tutorial_title {{tutorial.active}}"
to something like
ng-class="tutorial_title {{tutorial.active}}"
See http://docs.angularjs.org/misc/faq and look for ng-class.
The API Guide has it all wrong (really Google?). With Maps API v2 you do not need to enable a layer to show yourself, there is a simple call to the GoogleMaps instance you created with your map.
The actual documentation that Google provides gives you your answer. You just need to
// map is a GoogleMap object
map.isMyLocationEnabled = true
// map is a GoogleMap object
map.setMyLocationEnabled(true);
and watch the magic happen.
Just make sure that you have location permission and requested it at runtime on API Level 23 (M) or above
I found a not-very-intuitive way to do this by using DUMP()
SELECT DUMP(A.NAME),
DUMP(A.surname),
DUMP(B.ordernum)
FROM customer A
JOIN orders B
ON A.id = B.id
It will return something like:
'Typ=1 Len=2: 0,48'
for each column.
Type=1
means VARCHAR2/NVARCHAR2
Type=2
means NUMBER/FLOAT
Type=12
means DATE
, etc.

Since you don't care, I chose the max ID for each number.
select tbl.* from tbl
inner join (
select max(id) as maxID, number from tbl group by number) maxID
on maxID.maxID = tbl.id
Query Explanation
select
tbl.* -- give me all the data from the base table (tbl)
from
tbl
inner join ( -- only return rows in tbl which match this subquery
select
max(id) as maxID -- MAX (ie distinct) ID per GROUP BY below
from
tbl
group by
NUMBER -- how to group rows for the MAX aggregation
) maxID
on maxID.maxID = tbl.id -- join condition ie only return rows in tbl
-- whose ID is also a MAX ID for a given NUMBER
I've noticed that if you set the theme in the AndroidManifest, it seems to get rid of that short time where you can see the action bar. So, try adding this to your manifest:
<android:theme="@android:style/Theme.NoTitleBar">
Just add it to your application
tag to apply it app-wide.
From your code, it looks like provider
is a variant or some other variable, and not an object.
Is Nothing
is for objects only, yet later you say it's a value that should either be NULL or NOT NULL, which would be handled by IsNull
.
Try using:
If Not IsNull(provider) Then
url = url & "&provider=" & provider
End if
Alternately, if that doesn't work, try:
If provider <> "" Then
url = url & "&provider=" & provider
End if
From official documentation. Maybe you can use it in your case.
When you need equal height, add .h-100 to the cards.

Even you don't need to measure the length of string. A ! operator can solve everything for you. Remember always: !(empty string) = true !(some string) = false
So you could write:
<input ng-model="somefield">
<span ng-show="!somefield">Sorry, the field is empty!</span>

Maven is trying to download m2e's lifecycle-mapping artifact, which M2E uses to determine how to process plugins within Eclipse (adding source folders, etc.). For some reason this artifact cannot be downloaded. Do you have an internet connection? Can other artifacts be downloaded from repositories? Proxy settings?
For more details from Maven, try turning M2E debug output on (Settings/Maven/Debug Output checkbox) and it might give you more details as to why it cannot download from the repository.
encodeURIComponent works fine for me. we can give the url like this in ajax call.The code shown below:
$.ajax({
cache: false,
type: "POST",
url: "http://atandra.mivamerchantdev.com//mm5/json.mvc?Store_Code=ATA&Function=Module&Module_Code=thub_connector&Module_Function=THUB_Request",
data: "strChannelName=" + $('#txtupdstorename').val() + "&ServiceUrl=" + encodeURIComponent($('#txtupdserviceurl').val()),
dataType: "HTML",
success: function (data) {
},
error: function (xhr, ajaxOptions, thrownError) {
}
});
Using lodash _.last(array) Gets the last element of array.
data = [1,2,3]_x000D_
last = _.last(data)_x000D_
console.log(last)
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.min.js"></script>
_x000D_
an alternative would be to do something like:
SELECT
CAST(P0.seconds as bigint) as seconds
FROM
(
SELECT
seconds
FROM
TableName
WHERE
ISNUMERIC(seconds) = 1
) P0
That's what I got:
Scanner scanner = new Scanner(System.in);
System.out.println("Please enter a nickname!");
while (!scanner.hasNext("[a-zA-Z]{3,8}+")) {
System.out.println("Nickname should contain only Alphabetic letters! At least 3 and max 8 letters");
scanner.next();
}
String nickname = scanner.next();
System.out.println("Thank you! Got " + nickname);
Read about regex Pattern here: https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html
If you created a file inside a new directory, instead of 'svn add newdir/newfile' use 'svn add newdir' because you need to add the directory. All the files inside the directory will be added by default.
Now we have to use android.hardware.camera2 as android.hardware.Camera is deprecated which will only work on API >23 FlashLight
public class MainActivity extends AppCompatActivity {
Button button;
Boolean light=true;
CameraDevice cameraDevice;
private CameraManager cameraManager;
private CameraCharacteristics cameraCharacteristics;
String cameraId;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button=(Button)findViewById(R.id.button);
cameraManager = (CameraManager)
getSystemService(Context.CAMERA_SERVICE);
try {
cameraId = cameraManager.getCameraIdList()[0];
} catch (CameraAccessException e) {
e.printStackTrace();
}
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(light){
try {
cameraManager.setTorchMode(cameraId,true);
} catch (CameraAccessException e) {
e.printStackTrace();
}
light=false;}
else {
try {
cameraManager.setTorchMode(cameraId,false);
} catch (CameraAccessException e) {
e.printStackTrace();
}
light=true;
}
}
});
}
}
This library rocks! https://craig.is/killing/mice
Mousetrap.bind('up up down down left right left right b a enter', function() {
highlight([21, 22, 23]);
});
You need to press the sequence a bit fast to highlight the code in that page though.
if you want to have a pipe to write/read data, you can use the http://docs.oracle.com/javase/6/docs/api/java/io/PipedWriter.html
The grep family of commands (incl egrep, fgrep) is the usual solution for this.
$ grep pattern filename
If you're searching source code, then ack may be a better bet. It'll search subdirectories automatically and avoid files you'd normally not search (objects, SCM directories etc.)
Direct Javascript calls between frames and/or windows are only allowed if they conform to the same-origin policy. If your window and iframe share a common parent domain you can set document.domain
to "domain lower") one or both such that they can communicate. Otherwise you'll need to look into something like the postMessage() API.
The EntityManager.flush()
operation can be used the write all changes to the database before the transaction is committed. By default JPA does not normally write changes to the database until the transaction is committed. This is normally desirable as it avoids database access, resources and locks until required. It also allows database writes to be ordered, and batched for optimal database access, and to maintain integrity constraints and avoid deadlocks. This means that when you call persist, merge, or remove the database DML INSERT
, UPDATE
, DELETE
is not executed, until commit, or until a flush is triggered.
In my case, I have tried to uninstall the node to use the other version of node but when i check node -v , it gives me same version again and again,
found a solution :- search your desired package:
brew search node
you can install the desired version if not install:
brew install node@10
node package already installed you need to unlink it first:
brew unlink node
And then you can link a different version:
brew link node@10
if required to link them with the --force and --overwrite
brew link --force --overwrite node@10
Since your example uses a generic List
, I assume you don't need an index or unique constraint on your data. A List
may contain duplicate values. If you want to insure a unique key, consider using a Dictionary<TKey, TValue>()
.
var list = new List<Tuple<int,string>>();
list.Add(Tuple.Create(1, "Andy"));
list.Add(Tuple.Create(1, "John"));
list.Add(Tuple.Create(3, "Sally"));
foreach (var item in list)
{
Console.WriteLine(item.Item1.ToString());
Console.WriteLine(item.Item2);
}
This works a little differently from other answers in that it unselects all options:
$("#baba option").prop("selected", false);

Tomcat sets a catalina.home system property. You can use this in your log4j properties file. Something like this:
log4j.rootCategory=DEBUG,errorfile
log4j.appender.errorfile.File=${catalina.home}/logs/LogFilename.log
On Debian (including Ubuntu), ${catalina.home}
will not work because that points at /usr/share/tomcat6 which has no link to /var/log/tomcat6. Here just use ${catalina.base}
.
If your using another container, try to find a similar system property, or define your own. Setting the system property will vary by platform, and container. But for Tomcat on Linux/Unix I would create a setenv.sh in the CATALINA_HOME/bin directory. It would contain:
export JAVA_OPTS="-Dcustom.logging.root=/var/log/webapps"
Then your log4j.properties would be:
log4j.rootCategory=DEBUG,errorfile
log4j.appender.errorfile.File=${custom.logging.root}/LogFilename.log
Alter table table_name modify table_name.column_name data_type AUTO_INCREMENT;
eg:
Alter table avion modify avion.av int AUTO_INCREMENT;
No you need to select it with correct name. If you gave the table you select from an alias you can use that though.
Try this until a non-no answer appears:
function parent() {
this.child;
interestingProperty = "5";
...
}
function child() {
this.parent;
...
}
a = new parent();
a.child = new child();
a.child.parent = a; // this gives the child a reference to its parent
alert(a.interestingProperty+" === "+a.child.parent.interestingProperty);
Use a DecimalFormat object with a format string of "0.#".
