can't you use a
System.out.printf("%n%,d",int name);
The comma in the printf
should add the commas into the %d
inter.
Not positive about it, but works for me.
you need to return when the readystate==4 e.g.
function httpGet(theUrl)
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
return xmlhttp.responseText;
}
}
xmlhttp.open("GET", theUrl, false );
xmlhttp.send();
}
Easiest way to do this as shown here, using the standard library class bitset.
To emulate the C# feature in a type-safe way, you'd have to write a template wrapper around the bitset, replacing the int arguments with an enum given as a type parameter to the template. Something like:
template <class T, int N>
class FlagSet
{
bitset<N> bits;
FlagSet(T enumVal)
{
bits.set(enumVal);
}
// etc.
};
enum MyFlags
{
FLAG_ONE,
FLAG_TWO
};
FlagSet<MyFlags, 2> myFlag;
$file = $_FILES["file"] ["tmp_name"];
$check_ext = strtolower(pathinfo($file,PATHINFO_EXTENSION));
if ($check_ext == "fileext") {
//code
}
else {
//code
}
Replace options with this snippet, will fix for Vanilla JavaScript Developers
options: {

scales: {

}]
},
legend: {
display: false
}
}

strcat
attempts to append the second parameter to the first. This won't work since you are assigning implicitly sized constant strings.
If all you want to do is print two strings out
printf("%s%s",str1,str2);
Would do.
You could do something like
char *str1 = calloc(sizeof("SSSS")+sizeof("KKKK")+1,sizeof *str1);
strcpy(str1,"SSSS");
strcat(str1,str2);
to create a concatenated string; however strongly consider using strncat/strncpy instead. And read the man pages carefully for the above. (oh and don't forget to free
str1 at the end).
Make sure you have the access to the directory you are trying to spool. I tried to spool to root and it did not created the file (e.g c:\test.txt
). You can check where you are spooling by issuing spool
command.
'a' in x
and a quick search reveals some nice information about it: http://docs.python.org/3/tutorial/datastructures.html#dictionaries
As far as I am aware, simply opening the file in write mode without append mode will erase the contents of the file.
ofstream file("filename.txt"); // Without append
ofstream file("filename.txt", ios::app); // with append
The first one will place the position bit at the beginning erasing all contents while the second version will place the position bit at the end-of-file bit and write from there.
I second Dave's idea. I'm not always fond of pivot tables, but in this case they are pretty straightforward to use.
Here are my results:
It was so simple to create it that I have even recorded a macro in case you need to do this with VBA:
Sub Macro2()
'
' Macro2 Macro
'
'
Range("Table1[[#All],[DATA]]").Select
ActiveWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:= _
"Table1", Version:=xlPivotTableVersion14).CreatePivotTable TableDestination _
:="Sheet3!R3C7", TableName:="PivotTable4", DefaultVersion:= _
xlPivotTableVersion14
Sheets("Sheet3").Select
Cells(3, 7).Select
With ActiveSheet.PivotTables("PivotTable4").PivotFields("DATA")
.Orientation = xlRowField
.Position = 1
End With
ActiveSheet.PivotTables("PivotTable4").AddDataField ActiveSheet.PivotTables( _
"PivotTable4").PivotFields("DATA"), "Count of DATA", xlCount
End Sub
You are doing it right, so I guess something else is at fault (not export-ing COLUMNS ?).
A trick to debug these cases is to make a specialized command (a closure for programming language guys). Create a shell script named diff-columns doing:
exec /usr/bin/diff -x -y -w -p -W "$COLUMNS" "$@"
and just use
svn diff "$@" --diff-cmd diff-columns
This way your code is cleaner to read and more modular (top-down approach), and you can test the diff-columns code thouroughly separately (bottom-up approach).
I found this solution:
Include this jar in your project
You could use String.Split method.
class ExampleClass
{
public ExampleClass()
{
string exampleString = "there is a cat";
// Split string on spaces. This will separate all the words in a string
string[] words = exampleString.Split(' ');
foreach (string word in words)
{
Console.WriteLine(word);
// there
// is
// a
// cat
}
}
}
For more information see Sam Allen's article about splitting strings in c# (Performance, Regex)
You can use this code:
<Button
android:id="@+id/img_sublist_carat"
android:layout_width="70dp"
android:layout_height="68dp"
android:layout_centerVertical="true"
android:layout_marginLeft="625dp"
android:contentDescription=""
android:background="@drawable/img_sublist_carat_selector"
android:visibility="visible" />
(Selector File) img_sublist_carat_selector.xml:
<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true"
android:state_pressed="true"
android:drawable="@drawable/img_sublist_carat_highlight" />
<item android:state_pressed="true"
android:drawable="@drawable/img_sublist_carat_highlight" />
<item android:drawable="@drawable/img_sublist_carat_normal" />
</selector>
A 50% padding wont center your child, it will place it below the center. I think you really want a padding-top of 25%. Maybe you're just running out of space as your content gets taller? Also have you tried setting the margin-top instead of padding-top?
EDIT: Nevermind, the w3schools site says
% Specifies the padding in percent of the width of the containing element
So maybe it always uses width? I'd never noticed.
What you are doing can be acheived using display:table though (at least for modern browsers). The technique is explained here.
It's a "native (platform-specific) size integer." It's internally represented as void*
but exposed as an integer. You can use it whenever you need to store an unmanaged pointer and don't want to use unsafe
code. IntPtr.Zero
is effectively NULL
(a null pointer).
You likely want to use gpg
instead of openssl
so see "Additional Notes" at the end of this answer. But to answer the question using openssl
:
To Encrypt:
openssl enc -aes-256-cbc -in un_encrypted.data -out encrypted.data
To Decrypt:
openssl enc -d -aes-256-cbc -in encrypted.data -out un_encrypted.data
Note: You will be prompted for a password when encrypting or decrypt.
Your best source of information for openssl enc
would probably be: https://www.openssl.org/docs/man1.1.1/man1/enc.html
Command line:
openssl enc
takes the following form:
openssl enc -ciphername [-in filename] [-out filename] [-pass arg]
[-e] [-d] [-a/-base64] [-A] [-k password] [-kfile filename]
[-K key] [-iv IV] [-S salt] [-salt] [-nosalt] [-z] [-md] [-p] [-P]
[-bufsize number] [-nopad] [-debug] [-none] [-engine id]
Explanation of most useful parameters with regards to your question:
-e
Encrypt the input data: this is the default.
-d
Decrypt the input data.
-k <password>
Only use this if you want to pass the password as an argument.
Usually you can leave this out and you will be prompted for a
password. The password is used to derive the actual key which
is used to encrypt your data. Using this parameter is typically
not considered secure because your password appears in
plain-text on the command line and will likely be recorded in
bash history.
-kfile <filename>
Read the password from the first line of <filename> instead of
from the command line as above.
-a
base64 process the data. This means that if encryption is taking
place the data is base64 encoded after encryption. If decryption
is set then the input data is base64 decoded before being
decrypted.
You likely DON'T need to use this. This will likely increase the
file size for non-text data. Only use this if you need to send
data in the form of text format via email etc.
-salt
To use a salt (randomly generated) when encrypting. You always
want to use a salt while encrypting. This parameter is actually
redundant because a salt is used whether you use this or not
which is why it was not used in the "Short Answer" above!
-K key
The actual key to use: this must be represented as a string
comprised only of hex digits. If only the key is specified, the
IV must additionally be specified using the -iv option. When
both a key and a password are specified, the key given with the
-K option will be used and the IV generated from the password
will be taken. It probably does not make much sense to specify
both key and password.
-iv IV
The actual IV to use: this must be represented as a string
comprised only of hex digits. When only the key is specified
using the -K option, the IV must explicitly be defined. When a
password is being specified using one of the other options, the
IV is generated from this password.
-md digest
Use the specified digest to create the key from the passphrase.
The default algorithm as of this writing is sha-256. But this
has changed over time. It was md5 in the past. So you might want
to specify this parameter every time to alleviate problems when
moving your encrypted data from one system to another or when
updating openssl to a newer version.
Though you have specifically asked about OpenSSL you might want to consider using GPG instead for the purpose of encryption based on this article OpenSSL vs GPG for encrypting off-site backups?
To use GPG to do the same you would use the following commands:
To Encrypt:
gpg --output encrypted.data --symmetric --cipher-algo AES256 un_encrypted.data
To Decrypt:
gpg --output un_encrypted.data --decrypt encrypted.data
Note: You will be prompted for a password when encrypting or decrypt.
You need to either have the message be a fixed size, or you need to send the size or you need to use some separator characters.
This is the easiest case for a known size (100 bytes):
in = new DataInputStream(server.getInputStream());
byte[] message = new byte[100]; // the well known size
in.readFully(message);
In this case DataInputStream
makes sense as it offers readFully()
. If you don't use it, you need to loop yourself until the expected number of bytes is read.
For me the problem was tied to having the same file included in the bundle resources twice. Not sure how that happened, but I removed one of them and it compiled fine with the new build system.
I used 10.0.2.2 successfully on my home machine, but at work, it did not work. After hours of fooling around, I created a new emulator instance using the Android Virtual Device (AVD) manager, and finally the 10.0.2.2 worked.
I don't know what was wrong with the other emulator instance (the platform was the same), but if you find 10.0.2.2 does not work, try creating a new emulator instance.
Try this:
-1 * numeric_limits<double>::max()
Reference: numeric_limits
This class is specialized for each of the fundamental types, with its members returning or set to the different values that define the properties that type has in the specific platform in which it compiles.
If you have multiple Menus with Submenus, then you can go with the below solution.
HTML
<ul class="sidebar-menu" id="nav-accordion">
<li class="sub-menu">
<a href="" ng-click="hasSubMenu('dashboard')">
<i class="fa fa-book"></i>
<span>Dashboard</span>
<i class="fa fa-angle-right pull-right"></i>
</a>
<ul class="sub" ng-show="showDash">
<li><a ng-class="{ active: isActive('/dashboard/loan')}" href="#/dashboard/loan">Loan</a></li>
<li><a ng-class="{ active: isActive('/dashboard/recovery')}" href="#/dashboard/recovery">Recovery</a></li>
</ul>
</li>
<li class="sub-menu">
<a href="" ng-click="hasSubMenu('customerCare')">
<i class="fa fa-book"></i>
<span>Customer Care</span>
<i class="fa fa-angle-right pull-right"></i>
</a>
<ul class="sub" ng-show="showCC">
<li><a ng-class="{ active: isActive('/customerCare/eligibility')}" href="#/CC/eligibility">Eligibility</a></li>
<li><a ng-class="{ active: isActive('/customerCare/transaction')}" href="#/CC/transaction">Transaction</a></li>
</ul>
</li>
</ul>
There are two functions i have called first is ng-click = hasSubMenu('dashboard'). This function will be used to toggle the menu and it is explained in the code below. The ng-class="{ active: isActive('/customerCare/transaction')} it will add a class active to the current menu item.
Now i have defined some functions in my app:
First, add a dependency $rootScope which is used to declare variables and functions. To learn more about $roootScope refer to the link : https://docs.angularjs.org/api/ng/service/$rootScope
Here is my app file:
$rootScope.isActive = function (viewLocation) {
return viewLocation === $location.path();
};
The above function is used to add active class to the current menu item.
$rootScope.showDash = false;
$rootScope.showCC = false;
var location = $location.url().split('/');
if(location[1] == 'customerCare'){
$rootScope.showCC = true;
}
else if(location[1]=='dashboard'){
$rootScope.showDash = true;
}
$rootScope.hasSubMenu = function(menuType){
if(menuType=='dashboard'){
$rootScope.showCC = false;
$rootScope.showDash = $rootScope.showDash === false ? true: false;
}
else if(menuType=='customerCare'){
$rootScope.showDash = false;
$rootScope.showCC = $rootScope.showCC === false ? true: false;
}
}
By default $rootScope.showDash and $rootScope.showCC are set to false. It will set the menus to closed when page is initially loaded. If you have more than two submenus add accordingly.
hasSubMenu() function will work for toggling between the menus. I have added a small condition
if(location[1] == 'customerCare'){
$rootScope.showCC = true;
}
else if(location[1]=='dashboard'){
$rootScope.showDash = true;
}
it will remain the submenu open after reloading the page according to selected menu item.
I have defined my pages like:
$routeProvider
.when('/dasboard/loan', {
controller: 'LoanController',
templateUrl: './views/loan/view.html',
controllerAs: 'vm'
})
You can use isActive() function only if you have a single menu without submenu. You can modify the code according to your requirement. Hope this will help. Have a great day :)
By default, hibernate framework will immediately return id , when you are trying to save the entity using Save(entity)
method. There is no need to do it explicitly.
In case your primary key is int
you can use below code:
int id=(Integer) session.save(entity);
In case of string use below code:
String str=(String)session.save(entity);
If you don't need to support Windows, here's a really concise way to do it:
import os
hostname = "google.com" #example
response = os.system("ping -c 1 " + hostname)
#and then check the response...
if response == 0:
print hostname, 'is up!'
else:
print hostname, 'is down!'
This works because ping returns a non-zero value if the connection fails. (The return value actually differs depending on the network error.) You could also change the ping timeout (in seconds) using the '-t' option. Note, this will output text to the console.
the verbose mode will tell you everything
curl -v http://localhost
Sorry I am a beginner so my coding habit sucks!
public class TitleCase {
String title(String sent)
{
sent =sent.trim();
sent = sent.toLowerCase();
String[] str1=new String[sent.length()];
for(int k=0;k<=str1.length-1;k++){
str1[k]=sent.charAt(k)+"";
}
for(int i=0;i<=sent.length()-1;i++){
if(i==0){
String s= sent.charAt(i)+"";
str1[i]=s.toUpperCase();
}
if(str1[i].equals(" ")){
String s= sent.charAt(i+1)+"";
str1[i+1]=s.toUpperCase();
}
System.out.print(str1[i]);
}
return "";
}
public static void main(String[] args) {
TitleCase a = new TitleCase();
System.out.println(a.title(" enter your Statement!"));
}
}
There's of course the rather obvious:
Data[...,0] + 1j * Data[...,1]
You should really use Firebug or Webkit's console for debugging. Then you can just do console.debug(product);
and examine the object.
One possibility, take a look:
<script language="javascript" type="text/javascript" src="./jquery-3.1.1.slim.min.js" />
vs
<script language="javascript" type="text/javascript" src="./jquery-3.1.1.slim.min.js"></script>
The first method is actually wrong, however the browser does not complain at all. You need to be sure that you are indeed closing the javascript tag in the proper way.
You can not ask for instance during configuration phase - you can ask only for providers.
var app = angular.module('modx', []);
// configure stuff
app.config(function($routeProvider, $locationProvider) {
// you can inject any provider here
});
// run blocks
app.run(function($rootScope) {
// you can inject any instance here
});
See http://docs.angularjs.org/guide/module for more info.
Another option you can do, is the following:
li:before{
content:'';
padding: 0 0 0 25px;
background:url(../includes/images/layouts/featured-list-arrow.png) no-repeat 0 3px;
}
Use (0 3px) to position the list image.
Works in IE8+, Chrome, Firefox, and Opera.
I use this option because you can swap out list-style easily and a good chance you may not even have to use an image at all. (fiddle below)
http://jsfiddle.net/flashminddesign/cYAzV/1/
UPDATE:
This will account for text / content going into the second line:
ul{
list-style-type:none;
}
li{
position:relative;
}
ul li:before{
content:'>';
padding:0 10px 0 0;
position:absolute;
top:0; left:-10px;
}
Add padding-left: to the li if you want more space between the bullet and content.
I was checking how ax.axvline does work, and I've written a small function that resembles part of its idea:
import matplotlib.pyplot as plt
import matplotlib.lines as mlines
def newline(p1, p2):
ax = plt.gca()
xmin, xmax = ax.get_xbound()
if(p2[0] == p1[0]):
xmin = xmax = p1[0]
ymin, ymax = ax.get_ybound()
else:
ymax = p1[1]+(p2[1]-p1[1])/(p2[0]-p1[0])*(xmax-p1[0])
ymin = p1[1]+(p2[1]-p1[1])/(p2[0]-p1[0])*(xmin-p1[0])
l = mlines.Line2D([xmin,xmax], [ymin,ymax])
ax.add_line(l)
return l
So, if you run the following code you will realize how does it work. The line will span the full range of your plot (independently on how big it is), and the creation of the line doesn't rely on any data point within the axis, but only in two fixed points that you need to specify.
import numpy as np
x = np.linspace(0,10)
y = x**2
p1 = [1,20]
p2 = [6,70]
plt.plot(x, y)
newline(p1,p2)
plt.show()
I have created a working CodePen example to demonstrate how you might accomplish your goals.
I added ng-click
to the <form>
and removed the logic from your button:
<form name="addRelation" data-ng-click="save(model)">
...
<input class="btn" type="submit" value="SAVE" />
Here's the updated template:
<section ng-app="app" ng-controller="MainCtrl">
<form class="well" name="addRelation" data-ng-click="save(model)">
<label>First Name</label>
<input type="text" placeholder="First Name" data-ng-model="model.firstName" id="FirstName" name="FirstName" required/><br/>
<span class="text-error" data-ng-show="addRelation.submitted && addRelation.FirstName.$invalid">First Name is required</span><br/>
<label>Last Name</label>
<input type="text" placeholder="Last Name" data-ng-model="model.lastName" id="LastName" name="LastName" required/><br/>
<span class="text-error" data-ng-show="addRelation.submitted && addRelation.LastName.$invalid">Last Name is required</span><br/>
<label>Email</label>
<input type="email" placeholder="Email" data-ng-model="model.email" id="Email" name="Email" required/><br/>
<span class="text-error" data-ng-show="addRelation.submitted && addRelation.Email.$error.required">Email address is required</span>
<span class="text-error" data-ng-show="addRelation.submitted && addRelation.Email.$error.email">Email address is not valid</span><br/>
<input class="btn" type="submit" value="SAVE" />
</form>
</section>
and controller code:
app.controller('MainCtrl', function($scope) {
$scope.save = function(model) {
$scope.addRelation.submitted = true;
if($scope.addRelation.$valid) {
// submit to db
console.log(model);
} else {
console.log('Errors in form data');
}
};
});
I hope this helps.
Using calendar module:
Number-to-Abbr
calendar.month_abbr[month_number]
Abbr-to-Number
list(calendar.month_abbr).index(month_abbr)
I had the same issue, I cleaned and rebuilt the project and it worked.
I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics
If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.
Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.
Note: If you are using Bootstrap + AngularJS + UI Bootstrap, .left .right and .next classes are never added. Using the example at the following link and the CSS from Robert McKee answer works. I wanted to comment because it took 3 days to find a full solution. Hope this helps others!

If you use:
if (Array[i].compareToIgnoreCase(Array[j]) < 0)
you will get:
Example Hello is Sorting This
which I think is the output you were looking for.
AFAIK, you can't create a File
from an assets file because these are stored in the apk, that means there is no path to an assets folder.
But, you can try to create that File
using a buffer and the AssetManager
(it provides access to an application's raw asset files).
Try to do something like:
AssetManager am = getAssets();
InputStream inputStream = am.open("myfoldername/myfilename");
File file = createFileFromInputStream(inputStream);
private File createFileFromInputStream(InputStream inputStream) {
try{
File f = new File(my_file_name);
OutputStream outputStream = new FileOutputStream(f);
byte buffer[] = new byte[1024];
int length = 0;
while((length=inputStream.read(buffer)) > 0) {
outputStream.write(buffer,0,length);
}
outputStream.close();
inputStream.close();
return f;
}catch (IOException e) {
//Logging exception
}
return null;
}
Let me know about your progress.
Regarding to Peter's answer and Micheal's addition to it you may find How Do I Automatically Generate A .jar File In An Eclipse Java Project useful. Because even you have "*.jardesc" file on your project you have to run it manually. It may cools down your "eclipse click hassle" a bit.
I decided to share my finding on this error after resolving it myself.
First of all, BalusC solutions should be taken seriously but then there is another likely issue in Netbeans to be aware of especially when building an Enterprise Application Project(EAR) using Maven.
Netbeans generates, a parent POM file, an EAR project, an EJB project and a WAR project. Everything else in my project was fine, and I almost assumed the problem is a bug in probably GlassFish 4.0(I had to install and plug it into Netbeans) because GlassFish 4.1 has a Weld CDI bug which makes the embedded GlassFish 4.1 in Netbeans 8.0.2 unusable except through a patch.
Solution:
To resolve the "Target Unreachable, identifier 'bean' resolved to null" error-
I Right-click the parent POM project, and select Properties. A Project Properties Dialog appears, click "Sources", you will be surprised to see the "Source/Binary Format" set to 1.5 and "Encoding" set to Windows 1250. Change the "Source/Binary Format" to 1.6 0r 1.7, whichever you prefer to make your project CDI compliant, and "Encoding" to UTF-8.
Do the same for all the other subprojects(EAR, EJB, WAR) if they are not already compartible. Run your project, and you won't get that error again.
I hope this helps someone out there having similar error.
A summary and improvement of some of the answers.
import numpy as np

Another way of accomplishing this is using animation
which provides more control.
#content #nav a {
background-color: #FF0;
/* only animation-duration here is required, rest are optional (also animation-name but it will be set on hover)*/
animation-duration: 1s; /* same as transition duration */

animation-delay: 0ms; /* same as transition delay */
animation-iteration-count: 1; /* set to 2 to make it run twice, or Infinite to run forever!*/

gmdate()
is doing exactly what you asked for.
Look at formats here: http://php.net/manual/en/function.gmdate.php
You could just pass a static value (or a variable from *ngFor
or whatever)
<button (click)="toggle(1)" class="someclass">
<button (click)="toggle(2)" class="someclass">
If you're only looking for one:
import re
match = re.search(r'href=[\'"]?([^\'" >]+)', s)
if match:
print(match.group(1))
If you have a long string, and want every instance of the pattern in it:
import re
urls = re.findall(r'href=[\'"]?([^\'" >]+)', s)
print(', '.join(urls))
Where s
is the string that you're looking for matches in.
Quick explanation of the regexp bits:
r'...'
is a "raw" string. It stops you having to worry about escaping characters quite as much as you normally would. (\
especially -- in a raw string a\
is just a\
. In a regular string you'd have to do\\
every time, and that gets old in regexps.)"
href=[\'"]?
" says to match "href=", possibly followed by a'
or"
. "Possibly" because it's hard to say how horrible the HTML you're looking at is, and the quotes aren't strictly required.Enclosing the next bit in "
()
" says to make it a "group", which means to split it out and return it separately to us. It's just a way to say "this is the part of the pattern I'm interested in.""
[^\'" >]+
" says to match any characters that aren't'
,"
,>
, or a space. Essentially this is a list of characters that are an end to the URL. It lets us avoid trying to write a regexp that reliably matches a full URL, which can be a bit complicated.
The suggestion in another answer to use BeautifulSoup isn't bad, but it does introduce a higher level of external requirements. Plus it doesn't help you in your stated goal of learning regexps, which I'd assume this specific html-parsing project is just a part of.
It's pretty easy to do:
from BeautifulSoup import BeautifulSoup
soup = BeautifulSoup(html_to_parse)
for tag in soup.findAll('a', href=True):
print(tag['href'])
Once you've installed BeautifulSoup, anyway.
The following works well in a .php file.
<php? /*your block you want commented out*/ ?>
In Mac OS X, the solution is creating the file androidtool.cfg in our user .android folder and then add this line. Sure it is working also for Linux
sdkman.force.http=true
I hope that helps!
Are you able to reach that url from within the built-in browser?
If not, it means that your network setup is not correct. If you are in the emulator, you may have a look at the networking section of the docs.
If you are on OS/X, the emulator is using "the first" interface, en0 even if you are on wireless (en1), as en0 without a cable is still marked as up. You can issue ifconfig en0 down
and restart the emulator. I think I have read about similar behavior on Windows.
If you are on Wifi/3G, call your network provider for the correct DNS settings.
JQuery UI already has this, in my example below I included a maxchar attribute to focus on the next focus-able element (input, select, textarea, button and object) if i typed in the max number of characters
HTML:
text 1 <input type="text" value="" id="txt1" maxchar="5" /><br />
text 2 <input type="text" value="" id="txt2" maxchar="5" /><br />
checkbox 1 <input type="checkbox" value="" id="chk1" /><br />
checkbox 2 <input type="checkbox" value="" id="chk2" /><br />
dropdown 1 <select id="dd1" >
<option value="1">1</option>
<option value="1">2</option>
</select><br />
dropdown 2 <select id="dd2">
<option value="1">1</option>
<option value="1">2</option>
</select>
Javascript:
$(function() {
var focusables = $(":focusable");
focusables.keyup(function(e) {
var maxchar = false;
if ($(this).attr("maxchar")) {
if ($(this).val().length >= $(this).attr("maxchar"))
maxchar = true;
}
if (e.keyCode == 13 || maxchar) {
var current = focusables.index(this),
next = focusables.eq(current+1).length ? focusables.eq(current+1) : focusables.eq(0);
next.focus();
}
});
});

If you create an object, you get a more readable output and also gain an object with properties you can access:
$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NETFramework'
$obj = New-Object -TypeName psobject
Get-Item -Path $path | Select-Object -ExpandProperty Property | Sort | % {
$command = [String]::Format('(Get-ItemProperty -Path "{0}" -Name "{1}")."{1}"', $path, $_)
$value = Invoke-Expression -Command $command
$obj | Add-Member -MemberType NoteProperty -Name $_ -Value $value}
Write-Output $obj | fl
Sample output: InstallRoot : C:\Windows\Microsoft.NET\Framework\
And the object: $obj.InstallRoot = C:\Windows\Microsoft.NET\Framework\
The truth of the matter is this is way more complicated than it needs to be. Here is a much better example, and much simpler:
$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\.NETFramework'
$objReg = Get-ItemProperty -Path $path | Select -Property *
$objReg is now a custom object where each registry entry is a property name. You can view the formatted list via:
write-output $objReg
InstallRoot : C:\Windows\Microsoft.NET\Framework\
DbgManagedDebugger : "C:\windows\system32\vsjitdebugger.exe"
And you have access to the object itself:
$objReg.InstallRoot
C:\Windows\Microsoft.NET\Framework\
Also, you need to do something like this in config.xml if you are developing a customized module
<frontend>
<layout>
<updates>
<hpcustomer>
<file>hpcustomer.xml</file>
</hpcustomer>
</updates>
</layout>
</frontend>
Queue is an interface in java, you can not do that.
Instead you have two options:
option1:
Queue<Integer> Q = new LinkedList<>();
option2:
Queue<Integer> Q = new ArrayDeque<>();
I recommend using option2 as it is bit faster than the other
This worked for me. Put your cursor at the beginning of the word you want to replace, then
CtrlK, CtrlD, CtrlD ...
That should select as many instances of the word as you like, then you can just type the replacement.
I've tried the suggestions but ended up implementing it as follows
editView.setFilters(new InputFilter[]{new InputFilter()
{
@Override
public CharSequence filter(CharSequence source, int start, int end,
Spanned dest, int dstart, int dend)
{
String prefix = "http://";
//make sure our prefix is visible
String destination = dest.toString();
//Check If we already have our prefix - make sure it doesn't
//get deleted
if (destination.startsWith(prefix) && (dstart <= prefix.length() - 1))
{
//Yep - our prefix gets modified - try preventing it.
int newEnd = (dend >= prefix.length()) ? dend : prefix.length();
SpannableStringBuilder builder = new SpannableStringBuilder(
destination.substring(dstart, newEnd));
builder.append(source);
if (source instanceof Spanned)
{
TextUtils.copySpansFrom(
(Spanned) source, 0, source.length(), null, builder, newEnd);
}
return builder;
}
else
{
//Accept original replacement (by returning null)
return null;
}
}
}});
To set the directory selected path and the retrieve the new directory:
dlgBrowseForLogDirectory.SelectedPath = m_LogDirectory;
if (dlgBrowseForLogDirectory.ShowDialog() == DialogResult.OK)
{
txtLogDirectory.Text = dlgBrowseForLogDirectory.SelectedPath;
}
You need xlutils.copy
. Try something like this:
from xlutils.copy import copy
w = copy('book1.xls')
w.get_sheet(0).write(0,0,"foo")
w.save('book2.xls')
Keep in mind you can't overwrite cells by default as noted in this question.
It appears that this behavior is supposedly changed in the latest beta, which at the time of writing is beta 6.
From the release notes for iOS 10 Beta 6:
WKWebView
now defaults to respectinguser-scalable=no
from a viewport. Clients ofWKWebView
can improve accessibility and allow users to pinch-to-zoom on all pages by setting theWKWebViewConfiguration
propertyignoresViewportScaleLimits
toYES
.
However, in my (very limited) testing, I can't yet confirm this to be the case.
Edit: verified, iOS 10 Beta 6 respects user-scalable=no
by default for me.
You could use CONCAT, and the numeric argument of it is converted to its equivalent binary string form.
select t2.*
from t1 join t2
on t2.url=CONCAT('site.com/path/%', t1.id, '%/more') where t1.id > 9000
Here is the example i have tried and it is working for me:

I couldn't get Facebook to pick the right image from a specific post, so I did what's outlined on this page:
https://webapps.stackexchange.com/questions/18468/adding-meta-tags-to-individual-blogger-posts
In other words, something like this:
<b:if cond='data:blog.url == "http://urlofyourpost.com"'>
<meta content='http://urlofyourimage.png' property='og:image'/>
</b:if>
Basically, you're going to hard code an if statement into your site's HTML to get it to change the meta content for whatever you've changed for that one post. It's a messy solution, but it works.
I have a quick solution for finding Waldo using OpenCV.
I used the template matching function available in OpenCV to find Waldo.
To do this a template is needed. So I cropped Waldo from the original image and used it as a template.
Next I called the cv2.matchTemplate()
function along with the normalized correlation coefficient as the method used. It returned a high probability at a single region as shown in white below (somewhere in the top left region):
The position of the highest probable region was found using cv2.minMaxLoc()
function, which I then used to draw the rectangle to highlight Waldo:
I think you can simply change the query to return boolean as
@Query("select count(e)>0 from MyEntity e where ...")
PS:
If you are checking exists based on Primary key value CrudRepository
already have exists(id)
method.
column_obj != None
will produce a IS NOT NULL
constraint:
In a column context, produces the clause
a != b
. If the target isNone
, produces aIS NOT NULL
.
or use isnot()
(new in 0.7.9):
Implement the
IS NOT
operator.Normally,
IS NOT
is generated automatically when comparing to a value ofNone
, which resolves toNULL
. However, explicit usage ofIS NOT
may be desirable if comparing to boolean values on certain platforms.
Demo:
>>> from sqlalchemy.sql import column
>>> column('YourColumn') != None
<sqlalchemy.sql.elements.BinaryExpression object at 0x10c8d8b90>
>>> str(column('YourColumn') != None)
'"YourColumn" IS NOT NULL'
>>> column('YourColumn').isnot(None)
<sqlalchemy.sql.elements.BinaryExpression object at 0x104603850>
>>> str(column('YourColumn').isnot(None))
'"YourColumn" IS NOT NULL'
Try this way:
<td><a href="..." style="display:block;"> </a></td>
Also try this for C-indenting indentation. Do :help =

That will auto-indent the current code block you're in.
Or just:

to auto-indent the current line.
The requests
Python module takes care of both retrieving JSON data and decoding it, due to its builtin JSON decoder. Here is an example taken from the module's documentation:
>>> import requests
>>> r = requests.get('https://github.com/timeline.json')
>>> r.json()
[{u'repository': {u'open_issues': 0, u'url': 'https://github.com/...
So there is no use of having to use some separate module for decoding JSON.

Use square brackets to explore dictionaries.
The main differences between InnoDB and MyISAM ("with respect to designing a table or database" you asked about) are support for "referential integrity" and "transactions".
If you need the database to enforce foreign key constraints, or you need the database to support transactions (i.e. changes made by two or more DML operations handled as single unit of work, with all of the changes either applied, or all the changes reverted) then you would choose the InnoDB engine, since these features are absent from the MyISAM engine.
Those are the two biggest differences. Another big difference is concurrency. With MyISAM, a DML statement will obtain an exclusive lock on the table, and while that lock is held, no other session can perform a SELECT or a DML operation on the table.
Those two specific engines you asked about (InnoDB and MyISAM) have different design goals. MySQL also has other storage engines, with their own design goals.
So, in choosing between InnoDB and MyISAM, the first step is in determining if you need the features provided by InnoDB. If not, then MyISAM is up for consideration.
A more detailed discussion of differences is rather impractical (in this forum) absent a more detailed discussion of the problem space... how the application will use the database, how many tables, size of the tables, the transaction load, volumes of select, insert, updates, concurrency requirements, replication features, etc.
The logical design of the database should be centered around data analysis and user requirements; the choice to use a relational database would come later, and even later would the choice of MySQL as a relational database management system, and then the selection of a storage engine for each table.
Now you can add/use instances with in the method
public class Myprogram7 {
Scanner scan;
int compareCount = 0;
int low = 0;
int high = 0;
int mid = 0;
int key = 0;
Scanner temp;
int[]list;
String menu, outputString;
int option = 1;
boolean found = false;
private void readLine() {
}
private void findkey() {
}
private void printCount() {
}
public static void main(String[] args){
Myprogram7 myprg=new Myprogram7();
myprg.readLine();
myprg.findkey();
myprg.printCount();
}
}
Python datetime
objects don't have time zone info by default, and without it, Python actually violates the ISO 8601 specification (if no time zone info is given, assumed to be local time). You can use the pytz package to get some default time zones, or directly subclass tzinfo
yourself:
from datetime import datetime, tzinfo, timedelta
class simple_utc(tzinfo):
def tzname(self,**kwargs):
return "UTC"
def utcoffset(self, dt):
return timedelta(0)
Then you can manually add the time zone info to utcnow()
:
>>> datetime.utcnow().replace(tzinfo=simple_utc()).isoformat()
'2014-05-16T22:51:53.015001+00:00'
Note that this DOES conform to the ISO 8601 format, which allows for either Z
or +00:00
as the suffix for UTC. Note that the latter actually conforms to the standard better, with how time zones are represented in general (UTC is a special case.)
I believe all the existing answers contain the relevant information, but I would like to summarize.
The response object that is returned by requests
get and post operations contains two useful attributes:
response.text
- Contains str
with the response text.response.content
- Contains bytes
with the raw response content.You should choose one or other of these attributes depending on the type of response you expect.
response.text
response.content
.When writing responses to file you need to use the open function with the appropriate file write mode.
"w"
- plain write mode."wb"
- binary write mode.# Request the HTML for this web page:
response = requests.get("https://stackoverflow.com/questions/31126596/saving-response-from-requests-to-file")
with open("response.txt", "w") as f:
f.write(response.text)
# Request the profile picture of the OP:
response = requests.get("https://i.stack.imgur.com/iysmF.jpg?s=32&g=1")
with open("response.jpg", "wb") as f:
f.write(response.content)
The original code should work by using wb
and response.content
:
import requests
files = {'f': ('1.pdf', open('1.pdf', 'rb'))}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
file = open("out.xls", "wb")
file.write(response.content)
file.close()
But I would go further and use the with
context manager for open
.
import requests
with open('1.pdf', 'rb') as file:
files = {'f': ('1.pdf', file)}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
with open("out.xls", "wb") as file:
file.write(response.content)
Here's another approach:
sprintf("%02x", 10).upcase
see the documentation for sprintf
here: http://www.ruby-doc.org/core/classes/Kernel.html#method-i-sprintf
I don't see any mention of flexbox in here, so I will illustrate:
HTML
<div class="wrapper">
<div class="main">top</div>
<div class="footer">bottom</div>
</div>
CSS
.wrapper {
display: flex;
flex-direction: column;
min-height: 100vh;
}
.main {
flex: 1;
}
.footer {
flex: 0;
}
why don't you use width: 100%
and height: 100%
.
It is also possible to use the new button attribute called formtarget
that was introduced with HTML5.
<form>
<input type="submit" formtarget="_blank"/>
</form>
Below is the easiest way in case if Anaconda is already installed.
1) Under "Files", there is an option called,"Upload".
2) Click on "Upload" button and it asks for the path of the file and select the file and click on upload button present beside the file.

and the other way around.
By definition, that is impossible. IntentService
is a subclass of Service
, written in Java. Hence, anything an IntentService
does, a Service
could do, by including the relevant bits of code that IntentService
uses.
Starting a service with its own thread is like starting an IntentService. Is it not?
The three primary features of an IntentService
are:
the background thread
the automatic queuing of Intent
s delivered to onStartCommand()
, so if one Intent
is being processed by onHandleIntent()
on the background thread, other commands queue up waiting their turn
the automatic shutdown of the IntentService
, via a call to stopSelf()
, once the queue is empty
Any and all of that could be implemented by a Service
without extending IntentService
.
If you can update your connector to a version, which supports the new authentication plugin of MySQL 8, then do that. If that is not an option for some reason, change the default authentication method of your database user to native.

This is really good for converting a unix timestamp to a readable date along with day. Example:

In the launcher script you can force it, it permits to keep the same script and same launcher for both architecture
:: For 32 bits architecture, this line is sufficent (32bits is the only cscript available)
set CSCRIPT="cscript.exe"
:: Detect windows 64bits and use the expected cscript (SysWOW64 contains 32bits executable)
if exist "C:\Windows\SysWOW64\cscript.exe" set CSCRIPT="C:\Windows\SysWOW64\cscript.exe"
%CSCRIPT% yourscript.vbs
I like this one since it modifies tables, views, sequences and functions owner of a certain schema in one go (in one sql statement), without creating a function and you can use it directly in PgAdmin III and psql:
(Tested in PostgreSql v9.2)
DO $$DECLARE r record;
DECLARE
v_schema varchar := 'public';
v_new_owner varchar := '<NEW_OWNER>';
BEGIN
FOR r IN
select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.tables where table_schema = v_schema
union all
select 'ALTER TABLE "' || sequence_schema || '"."' || sequence_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.sequences where sequence_schema = v_schema
union all
select 'ALTER TABLE "' || table_schema || '"."' || table_name || '" OWNER TO ' || v_new_owner || ';' as a from information_schema.views where table_schema = v_schema
union all
select 'ALTER FUNCTION "'||nsp.nspname||'"."'||p.proname||'"('||pg_get_function_identity_arguments(p.oid)||') OWNER TO ' || v_new_owner || ';' as a from pg_proc p join pg_namespace nsp ON p.pronamespace = nsp.oid where nsp.nspname = v_schema

Absolutely possible. Many ways to do it. The fastest way, create condition with try - catch method.. try your certain font style condition, catch the error, and define the other font style.
I've found a way (workaround) to do this without making it sync.
So as it was mentioned before Promise.all
is all of none.
so... Use an enclosing promise to catch and force resolve.
let safePromises = originalPrmises.map((imageObject) => {
return new Promise((resolve) => {
// Do something error friendly
promise.then(_res => resolve(res)).catch(_err => resolve(err))
})
})
})
// safe
return Promise.all(safePromises)
Simply put:
SELECT *
FROM TABLE_NAME
WHERE
dob > '1/21/2012'
Where 1/21/2012 is the date and you want all data, including that date.
SELECT *
FROM TABLE_NAME
WHERE
dob BETWEEN '1/21/2012' AND '2/22/2012'
Use a between if you're selecting time between two dates
You only need
request.getParameterMap()
for getting the POST and GET - Parameters.
The Method returns a Map<String,String[]>
.
You can read the parameters in the Map by
Map<String, String[]> map = request.getParameterMap();
//Reading the Map
//Works for GET && POST Method
for(String paramName:map.keySet()) {
String[] paramValues = map.get(paramName);
//Get Values of Param Name
for(String valueOfParam:paramValues) {
//Output the Values
System.out.println("Value of Param with Name "+paramName+": "+valueOfParam);
}
}
How about:
foreach(var s in listBox1.Items.ToArray())
{
MessageBox.Show(s);
//do stuff with (s);
listBox1.Items.Remove(s);
}
The ToArray makes a copy of the list, so you don't need to worry about it changing the list while you are processing it.
Perhaps you may be compiling with file name instead of method name....Check once I too made the same mistake but I corrected it quickly .....#happy Coding
You also can use itemgetter operator:
from operator import itemgetter
my_tuples = [('c','r'), (2, 3), ('e'), (True, False),('text','sample')]
map(itemgetter(0), my_tuples)
What really worked to me: (source: oracle documentation "reading url")
import java.net.*;
import java.io.*;
public class UrlTextfile {
public static void main(String[] args) throws Exception {
URL oracle = new URL("http://yoursite.com/yourfile.txt");
BufferedReader in = new BufferedReader(
new InputStreamReader(oracle.openStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
}
}
After a lot of research, right now this is the most updated compiled library for Android that I found:
https://github.com/bravobit/FFmpeg-Android
FFmpeg release n4.0-39-gda39990
I had a similar error & this is what I found.
My environment details were as below: steps followed at my end
c:\>pip --version
pip 20.0.2 from c:\python37_64\lib\site-packages\pip (python 3.7)
C:\>python --version
Python 3.7.6
As per the documentation, apparently, python 3.7 already has the pickle package. So it does not require any additional download. I checked with the following command to make sure & it worked.
C:\Python\Experiements>python
Python 3.7.6 (tags/v3.7.6:43364a7ae0, Dec 19 2019, 00:42:30) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>>
So, pip install pickle
not required for python v3.7 for sure

For those of you complaining about "the submenus don't drop down", I solved it this way, which looks clean to me:
1) Besides your
<a class="dropdown-toggle disabled" href="http://google.com">
Dropdown <b class="caret"></b>
</a>
put a new
<a class="dropdown-toggle"><b class="caret"></b></a>
and remove the <b class="caret"></b>
tag, so it will look like
<a class="dropdown-toggle disabled" href="http://google.com">
Dropdown</a><a class="dropdown-toggle"><b class="caret"></b></a>
2) Style them with the following css rules:
.caret1 {
position: absolute !important; top: 0; right: 0;
}
.dropdown-toggle.disabled {
padding-right: 40px;
}
The style in .caret1 class is for positioning it absolutely inside your li
, at the right corner.
The second style is for adding some padding to the right of the dropdown to place the caret, preventing overlapping the text of the menu item.
Now you have a nice responsive menu item which looks nice both in desktop and mobile versions and that is both clickable and dropdownable depending on whether you click on the text or on the caret.
A simple bit of jQuery solved this problem for me.
$(function() {
$(window).bind('load', function() {
$("div.downloadProject").delay(1500).append('<iframe width="0" height="0" frameborder="0" src="[YOUR FILE SRC]"></iframe>');
});
});
In my HTML, I simply have
<div class="downloadProject"></div>
All this does is wait a second and a half, then append the div with the iframe referring to the file that you want to download. When the iframe is updated onto the page, your browser downloads the file. Simple as that. :D
Here is a tutorial for building a Debian package.
Basically, you need to:
I usually do all of this in my Makefile so I can just type make to spit out the binary and package it in one go.
You can use Apache Commons CollectionUtils:
if(CollectionUtils.containsAny(list1,list2)) {
// do whatever you want
} else {
// do other thing
}
This assumes that you have properly overloaded the equals functionality for your custom objects.
The char already has an IsDigit(char c) which does this:
public static bool IsDigit(char c)
{
if (!char.IsLatin1(c))
return CharUnicodeInfo.GetUnicodeCategory(c) == UnicodeCategory.DecimalDigitNumber;
if ((int) c >= 48)
return (int) c <= 57;
else
return false;
}
You can simply do this:
var theString = "839278";
bool digitsOnly = theString.All(char.IsDigit);
Actually the easiest way to change (only) port in development Django server is just like:
python manage.py runserver 7000
that should run development server on http://127.0.0.1:7000/
I also had the same problem. I used next way:
1.Added settings.xml file (~/.m2/settings.xml) with next content
<proxies>
<proxy>
<active>true</active>
<protocol>http</protocol>
<host>qq-proxya</host>
<port>8080</port>
<username>user</username>
<password>passw</password>
<nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
</proxy>
</proxies>
3. Using cmd go to folder with my project and wrote mvn clean and after that mvn install !
P.S. after that, when I add new dependency to my project I have to compile project using cmd(mvn compile). Because if I do it using eclipse plugin, I get error connecting with proxy connection.
Helpful tip - if you're using Spring data rest you need a different approach.
@Component
public class SpringDataRestCustomization extends RepositoryRestConfigurerAdapter {
@Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
config.getCorsRegistry().addMapping("/**")
.allowedOrigins("http://localhost:9000");
}
}
This answer explains what's going on behind the scenes, and the basics of how to solve this problem in any language. For reference, see the MDN docs on this topic.
You are making a request for a URL from JavaScript running on one domain (say domain-a.com) to an API running on another domain (domain-b.com). When you do that, the browser has to ask domain-b.com if it's okay to allow requests from domain-a.com. It does that with an HTTP OPTIONS
request. Then, in the response, the server on domain-b.com has to give (at least) the following HTTP headers that say "Yeah, that's okay":
HTTP/1.1 204 No Content // or 200 OK
Access-Control-Allow-Origin: https://domain-a.com // or * for allowing anybody
Access-Control-Allow-Methods: POST, GET, OPTIONS // What kind of methods are allowed
... // other headers
If you're in Chrome, you can see what the response looks like by pressing F12 and going to the "Network" tab to see the response the server on domain-b.com is giving.
So, back to the bare minimum from @threeve's original answer:
header := w.Header()
header.Add("Access-Control-Allow-Origin", "*")
if r.Method == "OPTIONS" {
w.WriteHeader(http.StatusOK)
return
}
This will allow anybody from anywhere to access this data. The other headers he's included are necessary for other reasons, but these headers are the bare minimum to get past the CORS (Cross Origin Resource Sharing) requirements.
java -cp CLASSPATH is necesssary if you wish to specify all code in the classpath. This is useful for debugging code.
The jarred executable format: java -jar JarFile
can be used if you wish to start the app with a single short command. You can specify additional dependent jar files in your MANIFEST using space separated jars in a Class-Path entry, e.g.:
Class-Path: mysql.jar infobus.jar acme/beans.jar
Both are comparable in terms of performance.
Try with this code -
It is a totally dynamic solution:
var form = $(document.createElement('form'));
$(form).attr("action", "reserves.php");
$(form).attr("method", "POST");
var input = $("<input>").attr("type", "hidden").attr("name", "mydata").val("bla");
$(form).append($(input));
$(form).submit();
If by "cursor speed", you mean the repeat rate when holding down a key - then have a look here: http://hints.macworld.com/article.php?story=20090823193018149
To summarize, open up a Terminal window and type the following command:
defaults write NSGlobalDomain KeyRepeat -int 0
More detail from the article:
Everybody knows that you can get a pretty fast keyboard repeat rate by changing a slider on the Keyboard tab of the Keyboard & Mouse System Preferences panel. But you can make it even faster! In Terminal, run this command:
defaults write NSGlobalDomain KeyRepeat -int 0
Then log out and log in again. The fastest setting obtainable via System Preferences is 2 (lower numbers are faster), so you may also want to try a value of 1 if 0 seems too fast. You can always visit the Keyboard & Mouse System Preferences panel to undo your changes.
You may find that a few applications don't handle extremely fast keyboard input very well, but most will do just fine with it.
It probably works with Javascript. When you click the link, nothing happens because it points to the current site. The javascript will then load a window or an url. It's used a lot in AJAX web apps.
At the beginning of your file you set raw_input

You can use URL Encoding Functions PHP has the

function
ASP has the
Server.URLEncode()
function
In JavaScript you can use the
encodeURIComponent()
function.
Solution by @omiday worked for me in Xvnc TigerVNC 1.1.0, so I condensed it into a single bash function vncsize x y. Use it like this: vncsize 1400 1000. It works for any VNC output name, "default" or "VNC-0".
function vncsize {
local x=$1 y=$2
local mode
if mode=$(cvt "$x" "$y" 2>/dev/null)
then
if [[ $mode =~ "Modeline (.*)$" ]]
then
local newMode=${BASH_REMATCH[1]//\"/}
local modeName=${newMode%% *}
local newSize=( ${modeName//[\"x_]/ } )
local screen=$(xrandr -q|grep connected|cut -d' ' -f1)

Another approach would be to create an embedded server to "host" your servlet, allowing you to write calls against it with libraries meant to make calls to actual servers (the usefulness of this approach somewhat depends on how easily you can make "legitimate" programatic calls to the server - I was testing a JMS (Java Messaging Service) access point, for which clients abound).
There are a couple of different routes you can go - the usual two are tomcat and jetty.
Warning: something to be mindful of when choosing the server to embed is the version of servlet-api you are using (the library which provides classes like HttpServletRequest). If you are using 2.5, I found Jetty 6.x to work well (which is the example I'll give below). If you're using servlet-api 3.0, the tomcat-7 embedded stuff seems to be a good option, however I had to abandon my attempt to use it, as the application I was testing used servlet-api 2.5. Trying to mix the two will result in NoSuchMethod and other such exceptions when attempting to configure or start the server.
You can set up such a server like this (Jetty 6.1.26, servlet-api 2.5):
public void startServer(int port, Servlet yourServletInstance){
Server server = new Server(port);
Context root = new Context(server, "/", Context.SESSIONS);
root.addServlet(new ServletHolder(yourServletInstance), "/servlet/context/path");
//If you need the servlet context for anything, such as spring wiring, you coudl get it like this
//ServletContext servletContext = root.getServletContext();
server.start();
}
I just give other option for this question - you need to use '.dt' in your code:
import pandas as pd_x000D_
_x000D_
df.index = pd.to_datetime(df.index)_x000D_
_x000D_
#for get year_x000D_
df.index.dt.year_x000D_
_x000D_
#for get month_x000D_
df.index.dt.month_x000D_
_x000D_
#for get day_x000D_
df.index.dt.day_x000D_
_x000D_
#for get hour_x000D_
df.index.dt.hour_x000D_
_x000D_
#for get minute_x000D_
df.index.dt.minute
_x000D_
Since all your values end with ".00", there will be no rounding issues, this will work

The other answers are correct but if you're doing numerical work, you might want to consider numpy. Using numpy, the answer is:

In case you are coming into this right now, I've just been through it today and can summarize where this stands. If you did not try this yet, some details here might help.
I think @Omid Ariyan's approach is the best way. Add the pre-commit and post-checkout scripts. DON'T forget to name them exactly the way Omid does and DON'T forget to make them executable. If you forget either of those, they have no effect and you run "git commit" over and over wondering why nothing happens :) Also, if you cut and paste out of the web browser, be careful that the quotation marks and ticks are not altered.
If you run the pre-commit script once (by running a git commit), then the file .permissions will be created. You can add it to the repository and I think it is unnecessary to add it over and over at the end of the pre-commit script. But it does not hurt, I think (hope).
There are a few little issues about the directory name and the existence of spaces in the file names in Omid's scripts. The spaces were a problem here and I had some trouble with the IFS fix. For the record, this pre-commit script did work correctly for me:
#!/bin/bash
SELF_DIR=`git rev-parse --show-toplevel`
DATABASE=$SELF_DIR/.permissions
# Clear the permissions database file
> $DATABASE
echo -n "Backing-up file permissions..."
IFSold=$IFS
IFS=$'\n'
for FILE in `git ls-files`
do
# Save the permissions of all the files in the index
echo $FILE";"`stat -c "%a;%U;%G" $FILE` >> $DATABASE
done
IFS=${IFSold}
# Add the permissions database file to the index
git add $DATABASE
echo "OK"
Now, what do we get out of this?
The .permissions file is in the top level of the git repo. It has one line per file, here is the top of my example:
$ cat .permissions
.gitignore;660;pauljohn;pauljohn
05.WhatToReport/05.WhatToReport.doc;664;pauljohn;pauljohn
05.WhatToReport/05.WhatToReport.pdf;664;pauljohn;pauljohn
As you can see, we have
filepath;perms;owner;group
In the comments about this approach, one of the posters complains that it only works with same username, and that is technically true, but it is very easy to fix it. Note the post-checkout script has 2 action pieces,
# Set the file permissions
chmod $PERMISSIONS $FILE
# Set the file owner and groups
chown $USER:$GROUP $FILE
So I am only keeping the first one, that's all I need. My user name on the Web server is indeed different, but more importantly you can't run chown unless you are root. Can run "chgrp", however. It is plain enough how to put that to use.
In the first answer in this post, the one that is most widely accepted, the suggestion is so use git-cache-meta, a script that is doing the same work that the pre/post hook scripts here are doing (parsing output from git ls-files
). These scripts are easier for me to understand, the git-cache-meta code is rather more elaborate. It is possible to keep git-cache-meta in the path and write pre-commit and post-checkout scripts that would use it.
Spaces in file names are a problem with both of Omid's scripts. In the post-checkout script, you'll know you have the spaces in file names if you see errors like this
$ git checkout -- upload.sh
Restoring file permissions...chmod: cannot access '04.StartingValuesInLISREL/Open': No such file or directory
chmod: cannot access 'Notebook.onetoc2': No such file or directory
chown: cannot access '04.StartingValuesInLISREL/Open': No such file or directory
chown: cannot access 'Notebook.onetoc2': No such file or directory
I'm checking on solutions for that. Here's something that seems to work, but I've only tested in one case
#!/bin/bash
SELF_DIR=`git rev-parse --show-toplevel`
DATABASE=$SELF_DIR/.permissions
echo -n "Restoring file permissions..."
IFSold=${IFS}
IFS=$
while read -r LINE || [[ -n "$LINE" ]];
do
FILE=`echo $LINE | cut -d ";" -f 1`
PERMISSIONS=`echo $LINE | cut -d ";" -f 2`
USER=`echo $LINE | cut -d ";" -f 3`
GROUP=`echo $LINE | cut -d ";" -f 4`
# Set the file permissions
chmod $PERMISSIONS $FILE
# Set the file owner and groups
chown $USER:$GROUP $FILE
done < $DATABASE
IFS=${IFSold}
echo "OK"

Since the permissions information is one line at a time, I set IFS to $, so only line breaks are seen as new things.
I read that it is VERY IMPORTANT to set the IFS environment variable back the way it was! You can see why a shell session might go badly if you leave $ as the only separator.
Um, why not just:
>>>> import os
>>>> os.path.join(dir_name, base_filename + "." + format)

JE
and JZ
are just different names for exactly the same thing: a
conditional jump when ZF
(the "zero" flag) is equal to 1.
(Similarly, JNE
and JNZ
are just different names for a conditional jump
when ZF
is equal to 0.)
You could use them interchangeably, but you should use them depending on what you are doing:
JZ
/JNZ
are more appropriate when you are explicitly testing
for something being equal to zero:
dec ecx
jz counter_is_now_zero
JE
and JNE
are more appropriate after a CMP
instruction:
cmp edx, 42
je the_answer_is_42
(A CMP
instruction performs a subtraction, and throws the value of the result away, while keeping the flags; which is why you get ZF=1
when the operands are equal
and ZF=0
when they're not.)
An additional reason could be a secondary mount inside your primary mount folder, e.g. after you worked on an SD card for an embedded device:
# mount /dev/sdb2 /mnt # root partition which contains /boot
# mount /dev/sdb1 /mnt/boot # boot partition
Unmounting /mnt will fail:
# umount /mnt
umount: /mnt: target is busy.
First we have to unmount the boot folder and then the root:
# umount /mnt/boot
# umount /mnt
Simply do this:
IF EXISTS (SELECT * FROM tablename)
BEGIN
DELETE from tablename
DBCC checkident ('tablename', reseed, 0)
END
Follow this steps:
-Build
-Generate Signed Apk
-Create new
Then fill up "New Key Store" form. If you wand to change .jnk file destination then chick on destination and give a name to get Ok button. After finishing it you will get "Key store password", "Key alias", "Key password" Press next and change your the destination folder. Then press finish, thats all. :)

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.

So I must use keytool to get sha-1. Here official Firebase doc:
I tried this really interesting solution today, which worked for me on an Ubuntu server. Some DNS or another issue in the apt
was making it adamant to not installing some packages from a custom PPA. What I did was install the apt-fast package and use it to install my packages instead of apt
.
apt-fast
is an alternative to apt
which works on top of apt
but uses aria2c
to download packages. It is used to increase the download speed. In my case, it also solved whatever network problem was making apt
to fail.
Using it is exactly the same as apt
:
sudo apt-fast install package-name
I don't know if this is a faster alternative, but I have another solution -
from datetime import datetime
start=datetime.now()
#Statements
print datetime.now()-start
This can be achieved using dplyr package, which is available in CRAN. The simple way to achieve this:
dplyr
package. library(dplyr)
df<- select(filter(dat,name=='tom'| name=='Lynn'), c('days','name))
Explanation:
So, once we’ve downloaded dplyr, we create a new data frame by using two different functions from this package:
filter: the first argument is the data frame; the second argument is the condition by which we want it subsetted. The result is the entire data frame with only the rows we wanted. select: the first argument is the data frame; the second argument is the names of the columns we want selected from it. We don’t have to use the names() function, and we don’t even have to use quotation marks. We simply list the column names as objects.
I would like to offer a generalized example for a very similar use case:
Use Case: I have a csv consisting of:
First|Third|Fifth
data|data|data
data|data|data
...billion more lines
I need to perform some transformations and the final csv needs to look like
First|Second|Third|Fourth|Fifth
data|null|data|null|data
data|null|data|null|data
...billion more lines
I need to do this because this is the schema defined by some model and I need for my final data to be interoperable with SQL Bulk Inserts and such things.
so:
1) I read the original csv using spark.read and call it "df".
2) I do something to the data.
3) I add the null columns using this script:
outcols = []
for column in MY_COLUMN_LIST:
if column in df.columns:
outcols.append(column)
else:
outcols.append(lit(None).cast(StringType()).alias('{0}'.format(column)))
df = df.select(outcols)
In this way, you can structure your schema after loading a csv (would also work for reordering columns if you have to do this for many tables).
If you just want to remove it from the existing array and not create a new one, try:
var items = [{Id: 1},{Id: 2},{Id: 3}];
items.splice(_.indexOf(items, _.find(items, function (item) { return item.Id === 2; })), 1);
Simple way is using location.origin
it will return your domain
ex
http://localhost:8000
https://yourdomain.com
then concat with some string...
Enjoy...
<img src={ location.origin+"/images/robot.svg"} alt="robot"/>
More images ?
var images =[
"img1.jpg",
"img2.png",
"img3.jpg",
]
images.map( (image,index) => (
<img key={index}
src={ location.origin+"/images/"+image}
alt="robot"
/>
) )
Uninstall your application from the emulator or device. Run the app again. (OnCreate() is not executed when the database already exists)
I know I'm kinda late to the party but I was looking for a solution for this..and I bumped into this post. Here is my take on this, maybe it will help some of you.
The html part:
<button type="button" class="btn btn-lg btn-danger" data-content="test" data-placement="right" data-toggle="popover" title="Popover title" >Hover to toggle popover</button><br>
// with custom html stored in a separate element, using "data-target"
<button type="button" class="btn btn-lg btn-danger" data-target="#custom-html" data-placement="right" data-toggle="popover" >Hover to toggle popover</button>
<div id="custom-html" style="display: none;">
<strong>Helloooo!!</strong>
</div>
The js part:
$(function () {
let popover = '[data-toggle="popover"]';
let popoverId = function(element) {
return $(element).popover().data('bs.popover').tip.id;
}
$(popover).popover({
trigger: 'manual',
html: true,
animation: false
})
.on('show.bs.popover', function() {
// hide all other popovers
$(popover).popover("hide");
})
.on("mouseenter", function() {
// add custom html from element
let target = $(this).data('target');
$(this).popover().data('bs.popover').config.content = $(target).html();
// show the popover
$(this).popover("show");
$('#' + popoverId(this)).on("mouseleave", () => {
$(this).popover("hide");
});
}).on("mouseleave", function() {
setTimeout(() => {
if (!$("#" + popoverId(this) + ":hover").length) {
$(this).popover("hide");
}
}, 100);
});
})
Adding this script to my code fixed the dropdown menu.
<script>
$(document).ready(function () {
$('.dropdown-toggle').dropdown();
});
</script>
As Frank pointed out, you need to use DISTINCT. Also, since you are using composite primary keys (which is perfectly fine, BTW) you need to make sure that you use the whole key in your joins:
SELECT
P.pe_name,
COUNT(DISTINCT O.ord_id) AS num_orders,
COUNT(I.item_id) AS num_items
FROM
People P
INNER JOIN Orders O ON
O.pe_id = P.pe_id
INNER JOIN Items I ON
I.ord_id = O.ord_id AND
I.pe_id = O.pe_id
GROUP BY
P.pe_name
Without I.ord_id = O.ord_id it was joining each item row to every order row for a person.
Try this one for current selection:
Sub A_SelectAllMakeTable2()
Dim tbl As ListObject
Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
tbl.TableStyle = "TableStyleMedium15"
End Sub
or equivalent of your macro (for Ctrl+Shift+End range selection):
Sub A_SelectAllMakeTable()
Dim tbl As ListObject
Dim rng As Range
Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
tbl.TableStyle = "TableStyleMedium15"
End Sub
If you are using more animation attributes the shorthand is:
animation: bubble 2s linear 0.5s 1 normal forwards;
This gives:
bubble
animation name2s
durationlinear
timing-function0.5s
delay1
iteration-count (can be 'infinite
')normal
directionforwards
fill-mode (set 'backwards' if you want to have compatibility to use the end position as the final state[this is to support browsers that has animations turned off]{and to answer only the title, and not your specific case})The unset
array_search
has some pretty terrible side effects because it can accidentally strip the first element off your array regardless of the value:
// bad side effects
$a = [0,1,2,3,4,5];
unset($a[array_search(3, $a)]);
unset($a[array_search(6, $a)]);
$this->log_json($a);
// result: [1,2,4,5]
// what? where is 0?
// it was removed because false is interpreted as 0
// goodness
$b = [0,1,2,3,4,5];
$b = array_diff($b, [3,6]);
$this->log_json($b);
// result: [0,1,2,4,5]
If you know that the value is guaranteed to be in the array, go for it, but I think the array_diff
is far safer. (I'm using php7)
For all those who are stuck with an error.
Let me give you guys a solution with a brief explanation of the same:-
command to connect:-
mongoexport --host your_host --port your_port -u your_username -p your_password --db your_db --collection your_collection --type=csv --out file_name.csv --fields all_the_fields --authenticationDatabase admin
--host --> host of Mongo server
--port --> port of Mongo server
-u --> username
-p --> password
--db --> db from which you want to export
--collection --> collection you want to export
--type --> type of export in my case CSV
--out --> file name where you want to export
--fields --> all the fields you want to export (don't give spaces in between two field name in between commas in case of CSV)
--authenticationDatabase --> database where all your user information is stored
The assertion libraries in Mocha work by throwing an error if the assertion was not correct. Throwing an error results in a rejected promise, even when thrown in the executor function provided to the catch
method.
.catch((error) => {
assert.isNotOk(error,'Promise error');
done();
});
In the above code the error
objected evaluates to true
so the assertion library throws an error... which is never caught. As a result of the error the done
method is never called. Mocha's done
callback accepts these errors, so you can simply end all promise chains in Mocha with .then(done,done)
. This ensures that the done method is always called and the error would be reported the same way as when Mocha catches the assertion's error in synchronous code.
it('should transition with the correct event', (done) => {
const cFSM = new CharacterFSM({}, emitter, transitions);
let timeout = null;
let resolved = false;
new Promise((resolve, reject) => {
emitter.once('action', resolve);
emitter.emit('done', {});
timeout = setTimeout(() => {
if (!resolved) {
reject('Timedout!');
}
clearTimeout(timeout);
}, 100);
}).then(((state) => {
resolved = true;
assert(state.action === 'DONE', 'should change state');
})).then(done,done);
});
I give credit to this article for the idea of using .then(done,done) when testing promises in Mocha.
Just in case if you have a loop or a json string that need to insert in the database. Try to replace the string with a single quote . here is my solution. example if you have a string that contain's a single quote.
String mystring = "Sample's";
String myfinalstring = mystring.replace("'","''");
String query = "INSERT INTO "+table name+" ("+field1+") values ('"+myfinalstring+"')";
this works for me in c# and java
If a we want to set the gravity of content inside a view then we will use "android:gravity", and if we want to set the gravity of this view (as a whole) within its parent view then we will use "android:layout_gravity".
Is it in your PATH? If so just run which git
in the terminal and it will tell you.
If the response code isn't 200 or 2xx, use getErrorStream()
instead of getInputStream().
I really like explanation by Jeremy west.... another approach which is really easy for understanding is given here http://courses.washington.edu/css343/zander/NotesProbs/heapcomplexity
since, buildheap depends using depends on heapify and shiftdown approach is used which depends upon sum of the heights of all nodes. So, to find the sum of height of nodes which is given by S = summation from i = 0 to i = h of (2^i*(h-i)), where h = logn is height of the tree solving s, we get s = 2^(h+1) - 1 - (h+1) since, n = 2^(h+1) - 1 s = n - h - 1 = n- logn - 1 s = O(n), and so complexity of buildheap is O(n).
There are a few issues with this query (and this apply to every query).
Lack of index on er101_upd_date_iso
column is most important thing as Oded has already mentioned.
Without matching index (which lack of could cause table scan) there is no chance to run fast queries on big tables.
If you cannot add indexes (for various reasons including there is no point in creating index for just one ad-hoc query) I would suggest a few workarounds (which can be used for ad-hoc queries):
Create temporary table on subset (rows and columns) of data you are interested in. Temporary table should be much smaller that original source table, can be indexed easily (if needed) and can cached subset of data which you are interested in.
To create temporary table you can use code (not tested) like:
-- copy records from last month to temporary table
INSERT INTO
#my_temporary_table
SELECT
*
FROM
er101_acct_order_dtl WITH (NOLOCK)
WHERE
er101_upd_date_iso > DATEADD(month, -1, GETDATE())
-- you can add any index you need on temp table
CREATE INDEX idx_er101_upd_date_iso ON #my_temporary_table(er101_upd_date_iso)
-- run other queries on temporary table (which can be indexed)
SELECT TOP 100
*
FROM
#my_temporary_table
ORDER BY
er101_upd_date_iso DESC
Pros:
view
.Cons:
Personally I use CTE a lot with ad-hoc queries -- it's help a lot with building (and testing) a query piece by piece.
See example below (the query starting with WITH
).
Pros:
Cons:
Similar to above, but create views instead of temporary tables (if you play often with the same queries and you have MS SQL version which supports indexed views.
You can create views or indexed views on subset of data you are interested in and run queries on view -- which should contain only interesting subset of data much smaller than the whole table.
Pros:
Cons:
Running star query (SELECT * FROM
) on big table is not good thing...
If you have large columns (like long strings) it takes a lot of time to read them from disk and pass by network.
I would try to replace *
with column names which you really need.
Or, if you need all columns try to rewrite query to something like (using common data expression):
;WITH recs AS (
SELECT TOP 100
id as rec_id -- select primary key only
FROM
er101_acct_order_dtl
ORDER BY
er101_upd_date_iso DESC
)
SELECT
er101_acct_order_dtl.*
FROM
recs
JOIN
er101_acct_order_dtl
ON
er101_acct_order_dtl.id = recs.rec_id
ORDER BY
er101_upd_date_iso DESC
Last thing which could speed up the ad-hoc query is allowing dirty reads with table hint WITH (NOLOCK)
.
Instead of hint you can set transaction isolation level to read uncommited:
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
or set proper SQL Management Studio setting.
I assume for ad-hoc queries dirty reads is good enough.
Only Objective-C is allowed by now... but since a few months ago you are allowed to write scripts that will be interpreted in your application.
So you may be able to write a LUA interpreter or a Python interpreter, then write some part of your application in this scripting language. If you want your application accepted on the App Store, these scripts have to be bundled with the application (your application cannot download it from the Internet for example)
If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents
export JAVA_OPTS="-server -Xmx512m"
For Windows you will need, in setenv.bat, something like
set JAVA_OPTS=-server -Xmx768m
Original answer here
After you run startup.bat
, you can easily confirm the correct settings have been applied provided you have turned @echo
on somewhere in your catatlina.bat
file (a good place could be immediately after echo Using CLASSPATH: "%CLASSPATH%"
):
One way to do it is to set the index to be auto incrementing. Then your SQL statement simply specifies NULL and then SQL parser does the rest for you.
INSERT INTO foo VALUES (null);
I'm very late in the game, but this might help others. I hit this same problem with $.get and I didn't want to blindly turn off caching and I didn't like the timestamp patch. So after a little research I found that you can simply use $.post instead of $.get which does NOT use caching. Simple as that. :)
use text untold class from android:
TextUtils.substring (charsequence source, int start, int end)
Yes. For that ensure that you declare the worksheet
For example
Previous Code
Sub Sample()
Dim ws As Worksheet
Set ws = Sheets("Sheet3")
Debug.Print ws.Cells(23, 4).Value
End Sub
New Code
Sub Sample()
Dim ws As Worksheet
Set ws = Sheets("Sheet4")
Debug.Print ws.Cells(23, 4).Value
End Sub
If you are planning to use the code in a production web application code,
using any web framework like Django/Flask, use projects like envparse, using it you can read the value as your defined type.
from envparse import env
# will read WHITE_LIST=hello,world,hi to white_list = ["hello", "world", "hi"]
white_list = env.list("WHITE_LIST", default=[])
# Perfect for reading boolean
DEBUG = env.bool("DEBUG", default=False)
NOTE: kennethreitz's autoenv is a recommended tool for making project specific environment variables, please note that those who are using autoenv
please keep the .env
file private (inaccessible to public)
If I understand your questions correctly, all you need to do is add the .Where(m => m.r.u.UserId == 1):
var UserInRole = db.UserProfiles.
Join(db.UsersInRoles, u => u.UserId, uir => uir.UserId,
(u, uir) => new { u, uir }).
Join(db.Roles, r => r.uir.RoleId, ro => ro.RoleId, (r, ro) => new { r, ro })
.Where(m => m.r.u.UserId == 1)
.Select (m => new AddUserToRole
{
UserName = m.r.u.UserName,
RoleName = m.ro.RoleName
});
Hope that helps.
This best for XML Deserialize
public static object Deserialize(string xml, Type toType)
{
using (MemoryStream memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(xml)))
{
System.IO.StreamReader str = new System.IO.StreamReader(memoryStream);
System.Xml.Serialization.XmlSerializer xSerializer = new System.Xml.Serialization.XmlSerializer(toType);
return xSerializer.Deserialize(str);
}
}
(Windows) If you have already installed MySQL server
cd C:\Program Files\MySQL\MySQL Server X.X\bin
mysqld --install
and still cannot connect, then the service did not start automatically. Just try
Start > Search "services"
and scroll down until you see "MySQLXX", where the XX represents the MySQL Server version. If the Status isn't "Started", then
Right Click > Start
If these are just going to be textblocks (and thus one way binding), and you just want to concatenate values, just bind two textblocks and put them in a horizontal stackpanel.
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Name}"/>
<TextBlock Text="{Binding ID}"/>
</StackPanel>
That will display the text (which is all Textblocks do) without having to do any more coding. You might put a small margin on them to make them look right though.
I've been using TextWrangler, it's pretty decent.
But I REALLY miss the Search and Replace and other capabilities of UltraEdit... enough that it's usually worth firing up Parallels to use it instead (UltraEdit runs poorly under Wine at the moment).
Try this one:
for (;;) {
if (!sc.hasNextInt()) {
System.out.println(" enter only integers!: ");
sc.next(); // discard
continue;
}
choose = sc.nextInt();
if (choose >= 0) {
System.out.print("no problem with input");
} else {
System.out.print("invalid inputs");
}
break;
}
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)

If no records are returned then it doesn't exist.
You would want to pass a pointer by reference if you have a need to modify the pointer rather than the object that the pointer is pointing to.
This is similar to why double pointers are used; using a reference to a pointer is slightly safer than using pointers.
The shortest way to filter your dataframe by date: Lets suppose your date column is type of datetime64[ns]
# filter by single day
df = df[df['date'].dt.strftime('%Y-%m-%d') == '2014-01-01']
# filter by single month
df = df[df['date'].dt.strftime('%Y-%m') == '2014-01']
# filter by single year
df = df[df['date'].dt.strftime('%Y') == '2014']
EDIT: After further investigation, my original assumption that this was an anomaly (bug?) of the declare @var datatype = value
syntax is incorrect.
I modified your script for 2005 since that syntax is not supported, then tried the modified version on 2008. In 2005, I get the Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes.
error message. In 2008, the modified script is still successful.
declare @KMsg varchar(max); set @KMsg = REPLICATE('a',1024);
declare @MMsg varchar(max); set @MMsg = REPLICATE(@KMsg,1024);
declare @GMsg varchar(max); set @GMsg = REPLICATE(@MMsg,1024);
declare @GGMMsg varchar(max); set @GGMMsg = @GMsg + @GMsg + @MMsg;
select LEN(@GGMMsg)
Try this instead:

Are you missing the reference to System.Configuration.dll? ConfigurationManager
class lies there.
EDIT: The System.Configuration
namespace has classes in mscorlib.dll, system.dll and in system.configuration.dll. Your project always include the mscorlib.dll and system.dll references, but system.configuration.dll must be added to most project types, as it's not there by default...

Did you add firefox to your path after you have started the selenium server? If that is the case selenium will still use old path. The solution is to tear down & restart selenium so that it will use the updated Path environment variable.
To check if firefox is added in your path correctly you can just launch a command line terminal "cmd" and type "firefox" + ENTER there. If firefox starts then everything is alright and restarting selenium server should fix the problem.

This works for Xamarin.Android. In OnCreate()

You need to name the file in both directory paths.
scp [email protected]:/dir/of/file.txt \local\dir\file.txt
You can use $anchorScroll
.
Just inject $anchorScroll
as a dependency, and call $anchorScroll()
whenever you want to scroll to top.
You can also use:
Range( RangeName ).end(xlDown).row
to find the last row with data in it starting at your named range.
strconv.Itoa(int(time.Now().Unix()))
You are getting close!
# Find all of the text between paragraph tags and strip out the html
page = soup.find('p').getText()
Using find (as you've noticed) stops after finding one result. You need find_all if you want all the paragraphs. If the pages are formatted consistently ( just looked over one), you could also use something like
soup.find('div',{'id':'ctl00_PlaceHolderMain_RichHtmlField1__ControlWrapper_RichHtmlField'})
to zero in on the body of the article.
In response to the good solution from macek. The solution didn't work for me. I have to bind the values of the datas to the export function. This solution works for me:
function exportToForm(a, b, c, d, e) {
console.log(a, b, c, d, e);
}
var images = document.getElementsByTagName("img");
for (var i=0, len=images.length, img; i<len; i++) {
var img = images[i];
var boundExportToForm = exportToForm.bind(undefined,
img.getAttribute("data-a"),
img.getAttribute("data-b"),
img.getAttribute("data-c"),
img.getAttribute("data-d"),
img.getAttribute("data-e"))
img.addEventListener("click", boundExportToForm);
}
just you pass this things in your select query. using CASE
CASE WHEN gender=0 then 'Female' WHEN gender=1 then 'Male' END as Genderdisp
My JSON
response was like this:
{"items":
[
{
"index": 1,
"name": "Samantha",
"rarity": "Scarborough",
"email": "[email protected]"
},
{
"index": 2,
"name": "Amanda",
"rarity": "Vick",
"email": "[email protected]"
}]
}
So, I used ng-repeat = "item in variables.items"
to display it.
Try this
var URL = "scratch.mit.edu/projects";
var mainURL = window.location.pathname;
if (mainURL == URL) {
mainURL += ( mainURL.match( /[\?]/g ) ? '&' : '#' ) + '_bypasssharerestrictions_';
console.log(mainURL)
}
The Substring
method works perfectly when you only want the Hours:Minutes:Seconds. It's simple, clean code and easy to understand.
var yourTimeSpan = DateTime.Now - DateTime.Now.AddMinutes(-2);
var formatted = yourTimeSpan.ToString().Substring(0,8);// 00:00:00
Console.WriteLine(formatted);
Depending on which event you actually want to use (textbox change
, or button click
), you can try this:
HTML:
<input id="color" type="text" onchange="changeBackground(this);" />
<br />
<span id="coltext">This text should have the same color as you put in the text box</span>
JS:
function changeBackground(obj) {
document.getElementById("coltext").style.color = obj.value;
}
DEMO: http://jsfiddle.net/6pLUh/
One minor problem with the button was that it was a submit button, in a form. When clicked, that submits the form (which ends up just reloading the page) and any changes from JavaScript are reset. Just using the onchange
allows you to change the color based on the input.
Also you can use f-string formatting to write integer to file
For appending use following code, for writing once replace 'a' with 'w'.
for i in s_list:
with open('path_to_file','a') as file:
file.write(f'{i}\n')
file.close()
Const: Const is nothing but "constant", a variable of which the value is constant but at compile time. And it's mandatory to assign a value to it. By default a const is static and we cannot change the value of a const variable throughout the entire program.
Static ReadOnly: A Static Readonly type variable's value can be assigned at runtime or assigned at compile time and changed at runtime. But this variable's value can only be changed in the static constructor. And cannot be changed further. It can change only once at runtime

You need to use the scrollTop
property.
document.getElementById('box').scrollTop
@Denis Danilenko solutions works for me, here's what I did: By the way I'm using VueJS CLI3 and NuxtJS here and with Bootstrap4, but it will work on VueJS without NuxtJS also:

id="dropdownMenuLink"
data-toggle="dropdown"

@click="showDropdown = !showDropdown"
@blur="unfocused">

aria-labelledby="dropdownMenuLink"
:class="showDropdown ? null : 'show'">
<nuxt-link class="dropdown-item" to="/contact">Contact</nuxt-link>

</div>
</div>
export default {
data() {
return {
showDropdown: true
}
},
methods: {
unfocused() {
this.showDropdown = !this.showDropdown;
}
}
}
based on Wesley Coetzee's answer i wrote this. Hope it can help anyone googling this issue. I had bugs with swapping the paginator size in the middle of the list that's why i submit my answer:

(page)="getPaginatorData($event)" [pageSizeOptions]="[10, 20, 30]"
showFirstLastButtons="false">
</mat-paginator>
<mat-list>
<app-newspaper-pagi-item *ngFor="let paper of (localNewspapers |
slice: lowValue : highValue)"
[newspaper]="paper">
</app-newspaper-pagi-item>
Component logic
import {Component, Input, OnInit} from "@angular/core";
import {PageEvent} from "@angular/material";
@Component({
selector: 'app-uniques-newspaper-list',
templateUrl: './newspaper-uniques-list.component.html',
})
export class NewspaperUniquesListComponent implements OnInit {
lowValue: number = 0;
highValue: number = 20;
// used to build an array of papers relevant at any given time
public getPaginatorData(event: PageEvent): PageEvent {
this.lowValue = event.pageIndex * event.pageSize;
this.highValue = this.lowValue + event.pageSize;
return event;
}
}

According to some comments on Super User it still works :) It just should be copied back to the plugins folder (if it's in the disabled folder) or downloaded from Plugins Central. I have downloaded it a few minutes ago and succeeded in using it.
Of course, be warned: this plugin COULD be unstable in some situations - that's why it was disabled.
If you are still thinking what the! You would not be alone, its actually not that complicated really, let me explain.
We want to turn the following list into a dictionary using the odd entries (counting from 1) as keys mapped to their consecutive even entries.
l = ["a", "b", "c", "d", "e"]
To create a dictionary we can use the built in dict
function for Mapping Types as per the manual the following methods are supported.
dict(one=1, two=2)
dict({'one': 1, 'two': 2})
dict(zip(('one', 'two'), (1, 2)))
dict([['two', 2], ['one', 1]])
The last option suggests that we supply a list of lists with 2 values or (key, value)
tuples, so we want to turn our sequential list into:
l = [["a", "b"], ["c", "d"], ["e",]]
We are also introduced to the zip
function, one of the built-in functions which the manual explains:
returns a list of tuples, where the i-th tuple contains the i-th element from each of the arguments
In other words if we can turn our list into two lists a, c, e
and b, d
then zip
will do the rest.
Slicings which we see used with Strings and also further on in the List section which mainly uses the range or short slice notation but this is what the long slice notation looks like and what we can accomplish with step:
>>> l[::2]
['a', 'c', 'e']
>>> l[1::2]
['b', 'd']
>>> zip(['a', 'c', 'e'], ['b', 'd'])
[('a', 'b'), ('c', 'd')]
>>> dict(zip(l[::2], l[1::2]))
{'a': 'b', 'c': 'd'}
Even though this is the simplest way to understand the mechanics involved there is a downside because slices are new list objects each time, as can be seen with this cloning example:
>>> a = [1, 2, 3]
>>> b = a
>>> b
[1, 2, 3]
>>> b is a
True
>>> b = a[:]
>>> b
[1, 2, 3]
>>> b is a
False
Even though b looks like a they are two separate objects now and this is why we prefer to use the grouper recipe instead.
Although the grouper is explained as part of the itertools module it works perfectly fine with the basic functions too.
Some serious voodoo right? =) But actually nothing more than a bit of syntax sugar for spice, the grouper recipe is accomplished by the following expression.
*[iter(l)]*2
Which more or less translates to two arguments of the same iterator wrapped in a list, if that makes any sense. Lets break it down to help shed some light.
>>> l*2
['a', 'b', 'c', 'd', 'e', 'a', 'b', 'c', 'd', 'e']
>>> [l]*2
[['a', 'b', 'c', 'd', 'e'], ['a', 'b', 'c', 'd', 'e']]
>>> [iter(l)]*2
[<listiterator object at 0x100486450>, <listiterator object at 0x100486450>]
>>> zip([iter(l)]*2)
[(<listiterator object at 0x1004865d0>,),(<listiterator object at 0x1004865d0>,)]
>>> zip(*[iter(l)]*2)
[('a', 'b'), ('c', 'd')]
>>> dict(zip(*[iter(l)]*2))
{'a': 'b', 'c': 'd'}
As you can see the addresses for the two iterators remain the same so we are working with the same iterator which zip then first gets a key from and then a value and a key and a value every time stepping the same iterator to accomplish what we did with the slices much more productively.
You would accomplish very much the same with the following which carries a smaller What the? factor perhaps.
>>> it = iter(l)
>>> dict(zip(it, it))
{'a': 'b', 'c': 'd'}
What about the empty key e
if you've noticed it has been missing from all the examples which is because zip
picks the shortest of the two arguments, so what are we to do.
Well one solution might be adding an empty value to odd length lists, you may choose to use append
and an if
statement which would do the trick, albeit slightly boring, right?
>>> if len(l) % 2:
... l.append("")
>>> l
['a', 'b', 'c', 'd', 'e', '']
>>> dict(zip(*[iter(l)]*2))
{'a': 'b', 'c': 'd', 'e': ''}
Now before you shrug away to go type from itertools import izip_longest
you may be surprised to know it is not required, we can accomplish the same, even better IMHO, with the built in functions alone.
I prefer to use the map() function instead of izip_longest() which not only uses shorter syntax doesn't require an import but it can assign an actual None
empty value when required, automagically.
>>> l = ["a", "b", "c", "d", "e"]
>>> l
['a', 'b', 'c', 'd', 'e']
>>> dict(map(None, *[iter(l)]*2))
{'a': 'b', 'c': 'd', 'e': None}
Comparing performance of the two methods, as pointed out by KursedMetal, it is clear that the itertools module far outperforms the map function on large volumes, as a benchmark against 10 million records show.
$ time python -c 'dict(map(None, *[iter(range(10000000))]*2))'
real 0m3.755s
user 0m2.815s

real 0m2.102s
user 0m1.451s
sys 0m0.539s
However the cost of importing the module has its toll on smaller datasets with map returning much quicker up to around 100 thousand records when they start arriving head to head.
$ time python -c 'dict(map(None, *[iter(range(100))]*2))'
