For ajax select2 multiple select dropdown i did like this;
//preset element values
//topics is an array of format [{"id":"","text":""}, .....]
$(id).val(topics);
setTimeout(function(){
ajaxTopicDropdown(id,
2,location.origin+"/api for gettings topics/",
"Pick a topic", true, 5);
},1);
// ajaxtopicDropdown is dry fucntion to get topics for diffrent element and url

string Index = i;
string FileName = "Mutton" + Index + ".xml";
XmlDocument xmlDoc = new XmlDocument();
var path = Path.Combine(Server.MapPath("~/Content/FilesXML"), FileName);
xmlDoc.Load(path); // Can use xmlDoc.LoadXml(YourString);
this is the best Solution to get the path what is exactly need for now
You can use the find function:
if($('#popup').find('p.filled-text').length !== 0)
// Do Stuff
This example works perfectly in Android
In kotlin you can use a lambda expression for this. The Kotlin Array Constructor definition is:
Array(size: Int, init: (Int) -> T)
Which evaluates to:
skillsSummaryDetailLinesArray = Array(linesLen) {
i: Int -> skillsSummaryDetailLines!!.getString(i)
}
Or:
skillsSummaryDetailLinesArray = Array<String>(linesLen) {
i: Int -> skillsSummaryDetailLines!!.getString(i)
}
In this example the field definition was:
private var skillsSummaryDetailLinesArray: Array<String>? = null

Download the code from github into the node_modules directory

that should do it.
if the module has dependancies and has a package.json, open the module and enter npm install.

"Significant" is entirely dependent on context.
If you're using reflection to create a single handler object based on some configuration file, and then spending the rest of your time running database queries, then it's insignificant. If you're creating large numbers of objects via reflection in a tight loop, then yes, it's significant.
In general, design flexibility (where needed!) should drive your use of reflection, not performance. However, to determine whether performance is an issue, you need to profile rather than get arbitrary responses from a discussion forum.
For CentOS, Ubuntu and Fedora, the default directory is /usr/share/nginx/html
About the recalculation:
You can keep your set of random values from changing every time you make an adjustment, by adjusting the automatic recalculation
, to: manual recalculate
. (Re)calculations are then only done when you press F9. Or shift F9.
See this link (though for older excel version than the current 2013) for some info about it: https://support.office.com/en-us/article/Change-formula-recalculation-iteration-or-precision-73fc7dac-91cf-4d36-86e8-67124f6bcce4.

What is actually the most robust and elegant automated solution for deserializing JSON to TypeScript runtime class instances?
Using property decorators with ReflectDecorators to record runtime-accessible type information that can be used during a deserialization process provides a surprisingly clean and widely adaptable approach, that also fits into existing code beautifully. It is also fully automatable, and works for nested objects as well.
An implementation of this idea is TypedJSON, which I created precisely for this task:
@JsonObject
class Foo {
@JsonMember
name: string;
getName(): string { return this.name };
}
var foo = TypedJSON.parse('{"name": "John Doe"}', Foo);
foo instanceof Foo; // true
foo.getName(); // "John Doe"
Nice one, big thanks to Max.
I've wrapped the functionality in his answer into jQuery if anyone wants to use it.
(function($) {
$.fn.getCursorPosition = function() {
var input = this.get(0);
if (!input) return; // No (input) element found
if ('selectionStart' in input) {
// Standard-compliant browsers
return input.selectionStart;
} else if (document.selection) {
// IE
input.focus();
var sel = document.selection.createRange();
var selLen = document.selection.createRange().text.length;
sel.moveStart('character', -input.value.length);
return sel.text.length - selLen;
}
}
})(jQuery);
Assuming you have a JSON hash hanging around somewhere, to automatically convert it into something like WarHog's version, wrap your JSON hash contents in %q{hsh}
tags.
This seems to automatically add all the necessary escaped text like in WarHog's answer.
On a generic note, you can use a combination of ng-if and ng-style incorporate conditional changes with change in background image.
<span ng-if="selectedItem==item.id"
ng-style="{'background-image':'url(../images/'+'{{item.id}}'+'_active.png)',
'background-size':'52px 57px',
'padding-top':'70px',
'background-repeat':'no-repeat',
'background-position': 'center'}">
</span>
<span ng-if="selectedItem!=item.id"
ng-style="{'background-image':'url(../images/'+'{{item.id}}'+'_deactivated.png)',
'background-size':'52px 57px',
'padding-top':'70px',
'background-repeat':'no-repeat',
'background-position': 'center'}">
</span>
If you don't wan't to use ng-model there is ng-value
you can try.
Here's the fiddle for this: http://jsfiddle.net/Rg9sG/1/
I have been looking for the same solution and this worked for me...add an inline css tag to control the width of the input.
For example:
<input type="number" min="1" max="5" style="width: 2em;">
Combined with the min and max attributes you can control the width of the input.
Tried multiple of these, I switched to Cygwin instead which fixed python and some other problems I was having on Windows:
set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%
The single quotes do not indicate a string, they make it starts: 'C:\
instead of C:\
so
%name%
is the usual syntax for expanding a variable, the !name!
syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION
first, or by running the command prompt with CMD /V:ON
.
Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4
to keep the current PATH content, and add something to the end.
The best way I settled with is to set proxy environment variables right before using conda
or pip
install/update commands. Simply run:
set HTTP_PROXY=http://username:password@proxy_url:port
For example, your actual command could be like
set HTTP_PROXY=http://yourname:[email protected]_company.com:8080
If your company uses https proxy, then also
set HTTPS_PROXY=https://username:password@proxy_url:port
Once you exit Anaconda prompt then this setting is gone, so your username/password won't be saved after the session.
I didn't choose other methods mentioned in Anaconda documentation or some other sources, because they all require hardcoding of username/password into
.condarc
or .netrc
configuration files (also this won't work for PIP)All of these are unsafe and will require constant update later. And if you forget where to update? More troubleshooting will come your way...
React no longer support using a function like this href="javascript:void(0)"

Basically this is what you need to do:
in the first activity:
Intent intent = new Intent();
intent.setAction(this, SecondActivity.class);
intent.putExtra(tag, value);
startActivity(intent);
and in the second activtiy:
Intent intent = getIntent();
intent.getBooleanExtra(tag, defaultValue);
intent.getStringExtra(tag, defaultValue);
intent.getIntegerExtra(tag, defaultValue);
one of the get-functions will give return you the value, depending on the datatype you are passing through.
Since SQL Server 2019 varchar columns support UTF-8 encoding.
Thus, from now on, the difference is size.
In a database system that translates to difference in speed.
Less size = Less IO + Less Memory = More speed in general. Read the article above for the numbers.
Go for varchar in UTF8 from now on!
Only if you have big percentage of data with characters in ranges 2048 - 16383 and 16384 – 65535 - you will have to measure

Wherever you have Text
component in your page just you need to set style of the Text

Use a Macro.
Macro>Start Recording
Use the keyboard to make your changes in a repeatable manner e.g.
home>type "able">end>down arrow>home
Then go back to the menu and click stop recording then run a macro multiple times.
That should do it and no regex based complications!
I rather use the following method to get the input:
#include <iostream>
#include <string>
using namespace std;
int main(void) {
string name;
cout << "Hello, Input your name please: ";
getline(cin, name);
return 0;
}
It's actually super easy to use rather than defining the total length of array for a string which contains a space character.
When you use re.split
and the split pattern contains capturing groups, the groups are retained in the output. If you don't want this, use a non-capturing group instead.
Configure your Swift project to handle SQLite C calls:
Create bridging header file to the project. See the Importing Objective-C into Swift section of the Using Swift with Cocoa and Objective-C. This bridging header should import sqlite3.h:

Depending on why you are doing this, using a std::set might be a better idea than std::vector.
It allows each element to occur only once. If you add it multiple times, there will only be one instance to erase anyway. This will make the erase operation trivial. The erase operation will also have lower time complexity than on the vector, however, adding elements is slower on the set so it might not be much of an advantage.
This of course won't work if you are interested in how many times an element has been added to your vector or the order the elements were added.
Try to use ES6 syntax of set timeout. Normal javascript setTimeout() won't work in react js
setTimeout(
() => this.setState({ position: 100 }),
5000
);
The System.Windows.MessageBox.Show() method has an overload which takes an owner Window as the first parameter. If we create an invisible owner Window which we then close after a specified time, it's child message box would close as well.
Window owner = CreateAutoCloseWindow(dialogTimeout);
MessageBoxResult result = MessageBox.Show(owner, ...
So far so good. But how do we close a window if the UI thread is blocked by the message box and UI controls can't be accessed from a worker thread? The answer is - by sending a WM_CLOSE windows message to the owner window handle:
Window CreateAutoCloseWindow(TimeSpan timeout)
{
Window window = new Window()
{
WindowStyle = WindowStyle.None,
WindowState = System.Windows.WindowState.Maximized,
Background = System.Windows.Media.Brushes.Transparent,
AllowsTransparency = true,
ShowInTaskbar = false,
ShowActivated = true,
Topmost = true
};
window.Show();
IntPtr handle = new WindowInteropHelper(window).Handle;
Task.Delay((int)timeout.TotalMilliseconds).ContinueWith(
t => NativeMethods.SendMessage(handle, 0x10 /*WM_CLOSE*/, IntPtr.Zero, IntPtr.Zero));
return window;
}
And here is the import for the SendMessage Windows API method:
static class NativeMethods
{
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);
}
I thought I'd try code this up for fun:
graph = {
'1': ['2', '3', '4'],
'2': ['5', '6'],
'5': ['9', '10'],
'4': ['7', '8'],
'7': ['11', '12']
}
def bfs(graph, forefront, end):
# assumes no cycles
next_forefront = [(node, path + ',' + node) for i, path in forefront if i in graph for node in graph[i]]
for node,path in next_forefront:
if node==end:
return path
else:
return bfs(graph,next_forefront,end)
print bfs(graph,[('1','1')],'11')
# >>>
# 1, 4, 7, 11
If you want cycles you could add this:
for i, j in for_front: # allow cycles, add this code
if i in graph:
del graph[i]
You can simply add another join like this:
SELECT dashboard_data.headline, dashboard_data.message, dashboard_messages.image_id, images.filename
FROM dashboard_data
INNER JOIN dashboard_messages
ON dashboard_message_id = dashboard_messages.id
INNER JOIN images
ON dashboard_messages.image_id = images.image_id
However be aware that, because it is an INNER JOIN
, if you have a message without an image, the entire row will be skipped. If this is a possibility, you may want to do a LEFT OUTER JOIN
which will return all your dashboard messages and an image_filename only if one exists (otherwise you'll get a null)
SELECT dashboard_data.headline, dashboard_data.message, dashboard_messages.image_id, images.filename
FROM dashboard_data
INNER JOIN dashboard_messages
ON dashboard_message_id = dashboard_messages.id
LEFT OUTER JOIN images
ON dashboard_messages.image_id = images.image_id
The data.table
package has its IDate

AmtPaid = c(1000, 100, 200)
)
require(data.table)
dt[ , JoiningDate := as.IDate(JoiningDate, '%m/%d/%y') ]
For session cookies it doesn't seem to be supported in Tomcat yet. See the bug report Need to add support for HTTPOnly session cookie parameter. A somewhat involved work-around for now can be found here, which basically boils down to manually patching Tomcat. Can't really find an easy way to do it at this moment at this point I'm affraid.
To summarize the work-around, it involves downloading the 5.5 source, and then change the source in the following places:
org.apache.catalina.connector.Request.java
//this is what needs to be changed
//response.addCookieInternal(cookie);
//this is whats new
response.addCookieInternal(cookie, true);
}
org.apache.catalina.connectorResponse.addCookieInternal
public void addCookieInternal(final Cookie cookie) {
addCookieInternal(cookie, false);
}
public void addCookieInternal(final Cookie cookie, boolean HTTPOnly) {
if (isCommitted())
return;
final StringBuffer sb = new StringBuffer();
//web application code can receive a IllegalArgumentException
//from the appendCookieValue invokation
if (SecurityUtil.isPackageProtectionEnabled()) {
AccessController.doPrivileged(new PrivilegedAction() {
public Object run(){
ServerCookie.appendCookieValue
(sb, cookie.getVersion(), cookie.getName(),
cookie.getValue(), cookie.getPath(),
cookie.getDomain(), cookie.getComment(),
cookie.getMaxAge(), cookie.getSecure());
return null;
}
});
} else {
ServerCookie.appendCookieValue
(sb, cookie.getVersion(), cookie.getName(), cookie.getValue(),
cookie.getPath(), cookie.getDomain(), cookie.getComment(),
cookie.getMaxAge(), cookie.getSecure());
}
//of course, we really need to modify ServerCookie
//but this is the general idea
if (HTTPOnly) {
sb.append("; HttpOnly");
}
//if we reached here, no exception, cookie is valid
// the header name is Set-Cookie for both "old" and v.1 ( RFC2109 )
// RFC2965 is not supported by browsers and the Servlet spec
// asks for 2109.
addHeader("Set-Cookie", sb.toString());
cookies.add(cookie);
}

I eventually figured out there was a byte mark exception and removed it using this code:
string _byteOrderMarkUtf8 = Encoding.UTF8.GetString(Encoding.UTF8.GetPreamble());
if (xml.StartsWith(_byteOrderMarkUtf8))
{
var lastIndexOfUtf8 = _byteOrderMarkUtf8.Length-1;
xml = xml.Remove(0, lastIndexOfUtf8);
}
This worked perfectly for me, I was looking for a way to send two different values with options generated by MySQL, and the following is generic and dynamic:
$(this).find("option:selected").text();
As mentioned in one of the comments. With this I was able to create a dynamic function that works with all my selection boxes that I want to get both values, the option value and the text.
Few days ago I noticed that when updating the jQuery from 1.6 to 1.9 of the site I used this code, this stop working... probably was a conflict with another piece of code... anyway, the solution was to remove option from the find() call:
$(this).find(":selected").text();
That was my solution... use it only if you have any problem after updating your jQuery.
Try line-height

Try imaskjs. It has Number, RegExp and other masks. Very simple to extend.
There are few ways to specify default server.
First way - Specify default server first in list, if you keep your server configurations in one config file, like Dayo showed above.
Second way (better) More flexible - provide default_server
parameter for listen
instruction, for example:
server {
listen *:80 default_server;
root /www/project/public/;
}
More information here: Nginx doc / Listen
This way more useful when you keep server configurations in separate files and do not want to name those files alphabetically.
If the component is an EJB, then, there shouldn't be a problem injecting an EM.
But....In JBoss 5, the JAX-RS integration isn't great. If you have an EJB, you cannot use scanning and you must manually list in the context-param resteasy.jndi.resource. If you still have scanning on, Resteasy will scan for the resource class and register it as a vanilla JAX-RS service and handle the lifecycle.
This is probably the problem.
The answer shared by @mockinterface is correct. Although I would like to add my 2 cents to it.
If someone is using frameworks like scrapy
the you will have to use /html/body//a[contains(@href,'com')][2]/@href
along with get() like this:
response.xpath('//a[contains(@href,'com')][2]/@href').get()
Try this code:
[self.navigationController presentViewController:controller animated:YES completion:nil];
THE ANSWER BELOW IS THE GOOD ONE
You aren't using the data method correctly. The correct code to update data is:
$('#foo').data('num', num);
So your example would be:
var num = $('#foo').data("num") + 1;
console.log(num)
$('#foo').data('num', num);
console.log(num)
You can simply use the setdiff
function to get the packages that aren't installed and then install them. In the sample below, we check if the ggplot2
and Rcpp
packages are installed before installing them.
unavailable <- setdiff(c("ggplot2", "Rcpp"), rownames(installed.packages()))
install.packages(unavailable)
In one line, the above can be written as:
install.packages(setdiff(c("ggplot2", "Rcpp"), rownames(installed.packages())))
Try:
jQuery("#availability option:selected").val();
Or to get the text of the option, use text()
:
jQuery("#availability option:selected").text();

I was having this problem on a Windows 7 (64 bit) after a power outage. The SQLEXPRESS service was not started even though is status was set to 'Automatic' and the mahine had been rebooted several times. Had to start the service manually.
You might try passing actual types instead of strings.
import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4']
dtypes = [datetime, datetime, str, float]
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)
But it's going to be really hard to diagnose this without any of your data to tinker with.
And really, you probably want pandas to parse the the dates into TimeStamps, so that might be:
pd.read_csv(file, sep='\t', header=None, names=headers, parse_dates=True)
var myEle = document.getElementById("myElement");
if(myEle){
var myEleValue= myEle.value;
}
the return of getElementById is null if an element is not actually present inside the dom, so your if statement will fail, because null is considered a false value
I didn't find answer for this in the comments, here is how can be used:
Minifiacation tools (good ones) add a comment to your .min.js file:
//# sourceMappingURL=yourFileName.min.js.map
which will connect your .map file.
When the min.js and js.map files are ready...
Try this
void Function()
{
while (condition)
{
await Task.Delay(1);
}
}
This will make the program wait until the condition is not true. You can just invert it by adding a "!" infront of the condition so that it will wait until the condition is true.
Another reason to use object
over iframe is that object
sub resources (when an <object>
performs HTTP
requests) are considered as passive/display
in terms of Mixed content
, which means it's more secure when you must have Mixed content
.
Mixed content means that when you have https
but your resource is from http
.
Reference: https://developer.mozilla.org/en-US/docs/Web/Security/Mixed_content
Heres an example using: getDisplayMedia
document.body.innerHTML = '<video style="width: 100%; height: 100%; border: 1px black solid;"/>';
navigator.mediaDevices.getDisplayMedia()
.then( mediaStream => {
const video = document.querySelector('video');
video.srcObject = mediaStream;
video.onloadedmetadata = e => {
video.play();
video.pause();
};
})
.catch( err => console.log(`${err.name}: ${err.message}`));
Also worth checking out is the Screen Capture API docs.
It's better also to separate your logic in another method, or maybe in another class.
This method will help you retreive the DataGridViewCell object in which the text was found.
/// <summary>
/// Check if a given text exists in the given DataGridView at a given column index
/// </summary>
/// <param name="searchText"></param>
/// <param name="dataGridView"></param>
/// <param name="columnIndex"></param>
/// <returns>The cell in which the searchText was found</returns>
private DataGridViewCell GetCellWhereTextExistsInGridView(string searchText, DataGridView dataGridView, int columnIndex)
{
DataGridViewCell cellWhereTextIsMet = null;
// For every row in the grid (obviously)
foreach (DataGridViewRow row in dataGridView.Rows)
{
// I did not test this case, but cell.Value is an object, and objects can be null
// So check if the cell is null before using .ToString()
if (row.Cells[columnIndex].Value != null && searchText == row.Cells[columnIndex].Value.ToString())
{
// the searchText is equals to the text in this cell.
cellWhereTextIsMet = row.Cells[columnIndex];
break;
}
}
return cellWhereTextIsMet;
}
private void button_click(object sender, EventArgs e)
{
DataGridViewCell cell = GetCellWhereTextExistsInGridView(textBox1.Text, myGridView, 2);
if (cell != null)
{
// Value exists in the grid
// you can do extra stuff on the cell
cell.Style = new DataGridViewCellStyle { ForeColor = Color.Red };
}
else
{
// Value does not exist in the grid
}
}
UEFA or FIFA don't seem to provide any API to get the information you want. However, there are some third-party services which support that:
OPTA - Both commercial and free. They have incredible database about matches. Whoscored.com currently uses it.
Others: livescoreboards, xmlsoccer, ...
If you are using Kotlin then this will solve your problem.
val dataString = "/Date(1586583441106)/"
val date = Date(Long.parseLong(dataString.substring(6, dataString.length - 2)))
Here's the complete process in Kotlin:
the spinner adapter class:
class CustomSpinnerAdapter(
context: Context,
textViewResourceId: Int,
val list: List<User>
) : ArrayAdapter<User>(
context,
textViewResourceId,
list
) {
override fun getCount() = list.size
override fun getItem(position: Int) = list[position]
override fun getItemId(position: Int) = list[position].report.toLong()
override fun getView(position: Int, convertView: View?, parent: ViewGroup): View {
return (super.getDropDownView(position, convertView, parent) as TextView).apply {
text = list[position].name
}
}
override fun getDropDownView(position: Int, convertView: View?, parent: ViewGroup): View {
return (super.getDropDownView(position, convertView, parent) as TextView).apply {
text = list[position].name
}
}
}
and use it in your activity/fragment like this:
spinner.adapter = CustomerSalesSpinnerAdapter(
context,
R.layout.cuser_spinner_item,
userList
)
Why don't you use an image with an onclick
attribute?
For example:
<script>
function myfunction() {
}
</script>
<img src='Myimg.jpg' onclick='myfunction()'>
If you use this, check man sudo
too:
#!/bin/bash
sudo echo "Hi, I'm root"
sudo -u nobody echo "I'm nobody"
sudo -u 1000 touch /test_user
TextMate not for "advanced programmers". That does not make sense, TextMate contains everything an "advanced programmer" would want. It allows them to define a bundle that allows them to quickly set up the way they want their source code formatted, or one that follows the project guidelines, quick easy access to create entire structures and classes based on typing part of a construct and hitting tab.
TextMate is my tool of choice, it is fast, lightweight and yet contains all of the features I would want in a tool to program with. While it is not tightly integrated in Xcode, that is not a problem for me as I don't write software for Mac OS X. I write software for FreeBSD.
$("#closeLink").click(closeIt);
Let's say you want to call your function passing some args to it i.e., closeIt(1, false)
. Then, you should build an anonymous function and call closeIt
from it.
$("#closeLink").click(function() {
closeIt(1, false);
});
try this:
Dim ws as Worksheet
Set ws = Thisworkbook.Sheets("Sheet2")
With ws
.Range("E2").Formula = "=VLOOKUP(D2,Sheet1!$A:$C,1,0)"
End With
End Sub
This just the simplified version of what you want.
No need to use Application
if you will just output the answer in the Range("E2")
.
If you want to stick with your logic, declare the variables.
See below for example.
Sub Test()
Dim rng As Range
Dim ws1, ws2 As Worksheet
Dim MyStringVar1 As String
Set ws1 = ThisWorkbook.Sheets("Sheet1")
Set ws2 = ThisWorkbook.Sheets("Sheet2")
Set rng = ws2.Range("D2")
With ws2
On Error Resume Next 'add this because if value is not found, vlookup fails, you get 1004
MyStringVar1 = Application.WorksheetFunction.VLookup(rng, ws1.Range("A1:C65536").Value, 1, False)
On Error GoTo 0
If MyStringVar1 = "" Then MsgBox "Item not found" Else MsgBox MyStringVar1
End With
End Sub
Hope this get's you started.
Simplest of all solutions:
df = df.replace(r'^\s+$', np.nan, regex=True)
Mutex is basically mutual exclusion. Only one thread can acquire the resource at once. When one thread acquires the resource, no other thread is allowed to acquire the resource until the thread owning the resource releases. All threads waiting for acquiring resource would be blocked.
Semaphore is used to control the number of threads executing. There will be fixed set of resources. The resource count will gets decremented every time when a thread owns the same. When the semaphore count reaches 0 then no other threads are allowed to acquire the resource. The threads get blocked till other threads owning resource releases.
In short, the main difference is how many threads are allowed to acquire the resource at once ?
Both UTF8 and UTF-8 work for me.
The above were really close. Here's my solution:
Private Sub getDsClone(ByRef inClone As DataSet, ByVal matchStr As String, ByRef outClone As DataSet)
Dim i As Integer
outClone = inClone.Clone
Dim dv As DataView = inClone.Tables(0).DefaultView
dv.RowFilter = matchStr
Dim dt As New DataTable
dt = dv.ToTable
For i = 0 To dv.Count - 1
outClone.Tables(0).ImportRow(dv.Item(i).Row)
Next
End Sub
You can still use the Authorization header with OAuth 2.0. There is a Bearer type specified in the Authorization header for use with OAuth bearer tokens (meaning the client app simply has to present ("bear") the token). The value of the header is the access token the client received from the Authorization Server.
It's documented in this spec: https://tools.ietf.org/html/rfc6750#section-2.1
E.g.:
GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer mF_9.B5f-4.1JqM
Where mF_9.B5f-4.1JqM is your OAuth access token.
System.Data.SqlClient
is the .NET Framework Data Provider for SQL Server. ie .NET library for SQL Server.
I don't know where providerName=SqlServer
comes from. Could you be getting this confused with the provider keyword in your connection string? (I know I was :) )
In the web.config you should have the System.Data.SqlClient
as the value of the providerName attribute. It is the .NET Framework Data Provider you are using.
<connectionStrings>
<add
name="LocalSqlServer"
connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"
providerName="System.Data.SqlClient"
/>
</connectionStrings>

I had to use os.system, since subprocess was giving me a memory error for larger tasks. Reference for this problem here. So, in order to get the output of the os.system command I used this workaround:
import os
batcmd = 'dir'
result_code = os.system(batcmd + ' > output.txt')
if os.path.exists('output.txt'):
fp = open('output.txt', "r")
output = fp.read()
fp.close()
os.remove('output.txt')
print(output)
The equivalent command in svn is:
svn log --diff -r revision
As per different sources, I think the minimum length in E-164 format depends on country to country. For eg:
For Sweden : The minimum number length (excluding the country code) is 7 digits. - Official Source? (country code 46)
For Solomon Islands its 5 for fixed line phones. - Source (country code 677)
... and so on. So including country code, the minimum length is 9 digits for Sweden and 11 for Israel and 8 for Solomon Islands.
Edit (Clean Solution): Actually, Instead of validating an international phone number by having different checks like length etc, you can use the Google's libphonenumber library. It can validate a phone number in E164 format directly. It will take into account everything and you don't even need to give the country if the number is in valid E164 format. Its pretty good! Taking an example:
String phoneNumberE164Format = "+14167129018"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
PhoneNumber phoneNumberProto = phoneUtil.parse(phoneNumberE164Format, null);
boolean isValid = phoneUtil.isValidNumber(phoneNumberProto); // returns true if valid
if (isValid) {
// Actions to perform if the number is valid
} else {
// Do necessary actions if its not valid
}
} catch (NumberParseException e) {
System.err.println("NumberParseException was thrown: " + e.toString());
}
If you know the country for which you are validating the numbers, you don;t even need the E164 format and can specify the country in .parse
function instead of passing null
.
The answer by Larry Hastings has some great general advice about sockets, but there are a couple of mistakes as it pertains to how the recv(bufsize)
method works in the Python socket module.
So, to clarify, since this may be confusing to others looking to this for help:
recv(bufsize)
method is not optional. You'll get an error if you call recv()
(without the param).recv(bufsize)
is a maximum size. The recv will happily return fewer bytes if there are fewer available.See the documentation for details.
Now, if you're receiving data from a client and want to know when you've received all of the data, you're probably going to have to add it to your protocol -- as Larry suggests. See this recipe for strategies for determining end of message.
As that recipe points out, for some protocols, the client will simply disconnect when it's done sending data. In those cases, your while True
loop should work fine. If the client does not disconnect, you'll need to figure out some way to signal your content length, delimit your messages, or implement a timeout.
I'd be happy to try to help further if you could post your exact client code and a description of your test protocol.
If you want to extend the amount of time permitted for an ASP.NET script to execute then increase the Server.ScriptTimeout
value. The default is 90 seconds for .NET 1.x and 110 seconds for .NET 2.0 and later.
For example:
// Increase script timeout for current page to five minutes
Server.ScriptTimeout = 300;
This value can also be configured in your web.config
file in the httpRuntime
configuration element:
<!-- Increase script timeout to five minutes -->
<httpRuntime executionTimeout="300"
... other configuration attributes ...
/>
Please note according to the MSDN documentation:
"This time-out applies only if the debug attribute in the compilation element is False. Therefore, if the debug attribute is True, you do not have to set this attribute to a large value in order to avoid application shutdown while you are debugging."
If you've already done this but are finding that your session is expiring then increase the
ASP.NET HttpSessionState.Timeout
value:
For example:
// Increase session timeout to thirty minutes
Session.Timeout = 30;
This value can also be configured in your web.config
file in the sessionState
configuration element:
<configuration>
<system.web>
<sessionState
mode="InProc"
cookieless="true"
timeout="30" />
</system.web>
</configuration>
If your script is taking several minutes to execute and there are many concurrent users then consider changing the page to an Asynchronous Page. This will increase the scalability of your application.
The other alternative, if you have administrator access to the server, is to consider this long running operation as a candidate for implementing as a scheduled task or a windows service.
Where you have written the code
public class Main {
public static void main(String args[])
{
Calculate obj = new Calculate(1,2,'+');
obj.getAnswer();
}
}
Here you have to run the class "Main" instead of the class you created at the start of the program. To do so pls go to Run Configuration and search for this class name"Main" which is having the main method inside this(public static void main(String args[])). And you will get your output.
1. Style parent element: style="display:flex; flex-direction:column; flex:1;"
2. Style the element you want to stay at bottom: style="margin-top: auto;"
3. Done! Wow. That was easy.
Example:
<section style="display:flex; flex-wrap:wrap;"> // For demo, not necessary
<div style="display:flex; flex-direction:column; flex:1;"> // Parent element
<button style="margin-top: auto;"> I </button> // Target element
</div>
... 5 more identical divs, for demo ...
</section>
As already mentioned, you will need to use a formatted result; which is all done through the Write()
, WriteLine()
, Format()
, and ToString()
methods.
What has not been mentioned is the Fixed-point Format which allows for a specified number of decimal places. It uses an 'F' and the number following the 'F' is the number of decimal places outputted, as shown in the examples.
Console.WriteLine("{0:F2}", 12); // 12.00 - two decimal places
Console.WriteLine("{0:F0}", 12.3); // 12 - ommiting fractions
Relying on the compiler vendor's implementation of primitive type sizes WILL come back to haunt you if you ever compile your code on another machine architecture, OS, or another vendor's compiler .
Most compiler vendors provide a header file that defines primitive types with
explict type sizes.
These primitive types should be used when ever code may be potentially ported
to another compiler (read this as ALWAYS in EVERY instance).
For example, most UNIX compilers have int8_t uint8_t int16_t int32_t uint32_t
.
Microsoft has INT8 UINT8 INT16 UINT16 INT32 UINT32
.
I prefer Borland/CodeGear's int8 uint8 int16 uint16 int32 uint32
.
These names also give a little reminder of the size/range of the intended value.
For years I have used Borland's explicit primitive type names
and #include
the following C/C++ header file (primitive.h)
which is intended to define the explicit primitive types with these names for any C/C++ compiler
(this header file might not actually cover every compiler but it covers several compilers I have used on Windows, UNIX and Linux, it also doesn't (yet) define 64bit types).
#ifndef primitiveH
#define primitiveH
// Header file primitive.h
// Primitive types
// For C and/or C++
// This header file is intended to define a set of primitive types
// that will always be the same number bytes on any operating operating systems
// and/or for several popular C/C++ compiler vendors.
// Currently the type definitions cover:
// Windows (16 or 32 bit)
// Linux
// UNIX (HP/US, Solaris)
// And the following compiler vendors
// Microsoft, Borland/Imprise/CodeGear, SunStudio, HP/UX
// (maybe GNU C/C++)
// This does not currently include 64bit primitives.
#define float64 double
#define float32 float
// Some old C++ compilers didn't have bool type
// If your compiler does not have bool then add emulate_bool
// to your command line -D option or defined macros.
#ifdef emulate_bool

John Resig, author of jQuery, submitted his version of cross-browser implementation of addEvent

to circumvent compatibility issues with IE's improper or non-existent addEventListener
.
function addEvent( obj, type, fn ) {

obj['e'+type+fn] = fn;
obj[type+fn] = function(){obj['e'+type+fn]( window.event );}
obj.attachEvent( 'on'+type, obj[type+fn] );
} else
obj.addEventListener( type, fn, false );
}
function removeEvent( obj, type, fn ) {
if ( obj.detachEvent ) {
obj.detachEvent( 'on'+type, obj[type+fn] );
obj[type+fn] = null;
} else
obj.removeEventListener( type, fn, false );
}

Adding this answer partially because it fixed my problem of the same issue and so I can bookmark this question myself.
I was able to fix it by doing the following:
sudo apt-get install gcc-multilib g++-multilib
If you've installed a version of gcc
/ g++
that doesn't ship by default (such as g++-4.8
on lucid) you'll want to match the version as well:
sudo apt-get install gcc-4.8-multilib g++-4.8-multilib
You can test it by using this snipped code:
private static void Main(string[] args)
{
int threadCount = 0;
try
{
for (int i = 0; i < int.MaxValue; i ++)
{
new Thread(() => Thread.Sleep(Timeout.Infinite)).Start();
threadCount ++;
}
}
catch
{
Console.WriteLine(threadCount);
Console.ReadKey(true);
}
}
Beware of 32-bit and 64-bit mode of application.
I use the Description
attribute from the System.ComponentModel namespace. Simply decorate the enum:
private enum PublishStatusValue
{
[Description("Not Completed")]
NotCompleted,
Completed,
Error
};
Then use this code to retrieve it:
public static string GetDescription<T>(this T enumerationValue)
where T : struct
{
Type type = enumerationValue.GetType();
if (!type.IsEnum)
{
throw new ArgumentException("EnumerationValue must be of Enum type", "enumerationValue");
}
//Tries to find a DescriptionAttribute for a potential friendly name
//for the enum
MemberInfo[] memberInfo = type.GetMember(enumerationValue.ToString());
if (memberInfo != null && memberInfo.Length > 0)
{
object[] attrs = memberInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);
if (attrs != null && attrs.Length > 0)
{
//Pull out the description value
return ((DescriptionAttribute)attrs[0]).Description;
}
}
//If we have no description attribute, just return the ToString of the enum
return enumerationValue.ToString();
}
I know I am posting this answer little late, but I felt it is worth using Google's fuse location provider service to get the current location.
Main features of this api are :
1.Simple APIs: Lets you choose your accuracy level as well as power consumption.
2.Immediately available: Gives your apps immediate access to the best, most recent location.
3.Power-efficiency: It chooses the most efficient way to get the location with less power consumptions
4.Versatility: Meets a wide range of needs, from foreground uses that need highly accurate location to background uses that need periodic location updates with negligible power impact.
It is flexible in while updating in location also.
If you want current location only when your app starts then you can use getLastLocation(GoogleApiClient)
method.
If you want to update your location continuously then you can use requestLocationUpdates(GoogleApiClient,LocationRequest, LocationListener)
You can find a very nice blog about fuse location here and google doc for fuse location also can be found here.
Update
According to developer docs starting from Android O they have added new limits on background location.
If your app is running in the background, the location system service computes a new location for your app only a few times each hour. This is the case even when your app is requesting more frequent location updates. However if your app is running in the foreground, there is no change in location sampling rates compared to Android 7.1.1 (API level 25).
You may also want to use hasOwnProperty in the loop.
for (var prop in obj) {
if (obj.hasOwnProperty(prop)) {
switch (prop) {
// obj[prop] has the value
}
}
}
node.js is single-threaded which means your script will block whether you want it or not. Remember that V8 (Google's Javascript engine that node.js uses) compiles Javascript into machine code which means that most basic operations are really fast and looping through an object with 100 keys would probably take a couple of nanoseconds?
However, if you do a lot more inside the loop and you don't want it to block right now, you could do something like this
switch (prop) {
case 'Timestamp':
setTimeout(function() { ... }, 5);
break;
case 'Start_Value':
setTimeout(function() { ... }, 10);
break;
}
If your loop is doing some very CPU intensive work, you will need to spawn a child process to do that work or use web workers.
Keep it simple, folks!
export class HeroesComponent implements OnInit {
heroes: Hero[];
window = window;
}
<div>{{window.Object.entries({ foo: 1 }) | json}}</div>
Aditya or others, can you join or match up t2 with t1 in your example, i.e. translated to my code,
with t1 as (select * from AA where FIRSTNAME like 'Kermit'),
t2 as (select * from BB B join t1 on t1.FIELD1 = B.FIELD1)
I am not clear whether only WHERE is supported for joining, or what joining approach is supported within the 2nd WITH entity. Some of the examples have the WHERE A=B down in the body of the select "below" the WITH clauses.
The error I'm getting following these WITH declarations is the identifiers (field names) in B are not recognized, down in the body of the rest of the SQL. So the WITH syntax seems to run OK, but cannot access the results from t2.
Use substr with parameter -1:
"linto.yahoo.com.".substr(-1);
equals "."
Note:
To extract characters from the end of the string, use a negative start number (This does not work in IE 8 and earlier).
A quick workaround that worked for me: try using the local ip address (127.0.0.1) instead of 'localhost' in mysql_connect(). This "forces" php to connect through TCP/IP instead of a unix socket.
EDIT: Updated for jQuery 1.8
jQuery 1.8 will add browser specific transformations. jsFiddle Demo
var rotation = 0;
jQuery.fn.rotate = function(degrees) {
$(this).css({'transform' : 'rotate('+ degrees +'deg)'});
return $(this);
};
$('.rotate').click(function() {
rotation += 5;
$(this).rotate(rotation);
});
EDIT: Added code to make it a jQuery function.
For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.
var rotation = 0;
jQuery.fn.rotate = function(degrees) {
$(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
'-moz-transform' : 'rotate('+ degrees +'deg)',
'-ms-transform' : 'rotate('+ degrees +'deg)',
'transform' : 'rotate('+ degrees +'deg)'});
return $(this);
};
$('.rotate').click(function() {
rotation += 5;
$(this).rotate(rotation);
});
EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.
Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.
Here is a jsFiddle.
If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.
HTML
<div class="rotate">
<h1>Rotatey text</h1>
</div>
CSS
/* Totally for style */
.rotate {
background: #F02311;
color: #FFF;
width: 200px;
height: 200px;
text-align: center;
font: normal 1em Arial;
position: relative;
top: 50px;
left: 50px;

I guess anther way, possibly faster, to achieve this is
1) Use dict comprehension to get desired dict (i.e., taking 2nd col of each array)
2) Then use pd.DataFrame
to create an instance directly from the dict without loop over each col and concat.
Assuming your mat
looks like this (you can ignore this since your mat
is loaded from file):
In [135]: mat = {'a': np.random.randint(5, size=(4,2)),
.....: 'b': np.random.randint(5, size=(4,2))}
In [136]: mat
Out[136]:
{'a': array([[2, 0],
[3, 4],
[0, 1],
[4, 2]]), 'b': array([[1, 0],
[1, 1],
[1, 0],
[2, 1]])}
Then you can do:
In [137]: df = pd.DataFrame ({name:mat[name][:,1] for name in mat})
In [138]: df
Out[138]:
a b
0 0 0
1 4 1
2 1 0
3 2 1
[4 rows x 2 columns]
This may help you find what you're looking for... Batch script loop
My answer is as follows:
@echo off
:start
set /a var+=1
if %var% EQU 100 goto end
:: Code you want to run goes here
goto start
:end
echo var has reached %var%.
pause
exit
The first set of commands under the start label loops until a variable, %var% reaches 100. Once this happens it will notify you and allow you to exit. This code can be adapted to your needs by changing the 100 to 17 and putting your code or using a call command followed by the batch file's path (Shift+Right Click on file and select "Copy as Path") where the comment is placed.
You probably need to specify which rows you want to update...
UPDATE
mytable
SET
column1 = value1,
column2 = value2
WHERE
key_value = some_value;
Objects never go out of scope in C# as they do in C++. They are dealt with by the Garbage Collector automatically when they are not used anymore. This is a more complicated approach than C++ where the scope of a variable is entirely deterministic. CLR garbage collector actively goes through all objects that have been created and works out if they are being used.
An object can go "out of scope" in one function but if its value is returned, then GC would look at whether or not the calling function holds onto the return value.
Setting object references to null
is unnecessary as garbage collection works by working out which objects are being referenced by other objects.
In practice, you don't have to worry about destruction, it just works and it's great :)
Dispose
must be called on all objects that implement IDisposable
when you are finished working with them. Normally you would use a using
block with those objects like so:
using (var ms = new MemoryStream()) {
//...
}
EDIT On variable scope. Craig has asked whether the variable scope has any effect on the object lifetime. To properly explain that aspect of CLR, I'll need to explain a few concepts from C++ and C#.
In both languages the variable can only be used in the same scope as it was defined - class, function or a statement block enclosed by braces. The subtle difference, however, is that in C#, variables cannot be redefined in a nested block.
In C++, this is perfectly legal:
int iVal = 8;
//iVal == 8
if (iVal == 8){
int iVal = 5;
//iVal == 5
}
//iVal == 8
In C#, however you get a a compiler error:
int iVal = 8;
if(iVal == 8) {
int iVal = 5; //error CS0136: A local variable named 'iVal' cannot be declared in this scope because it would give a different meaning to 'iVal', which is already used in a 'parent or current' scope to denote something else
}
This makes sense if you look at generated MSIL - all the variables used by the function are defined at the start of the function. Take a look at this function:
public static void Scope() {
int iVal = 8;
if(iVal == 8) {
int iVal2 = 5;
}
}
Below is the generated IL. Note that iVal2, which is defined inside the if block is actually defined at function level. Effectively this means that C# only has class and function level scope as far as variable lifetime is concerned.
.method public hidebysig static void Scope() cil managed
{
// Code size 19 (0x13)
.maxstack 2
.locals init ([0] int32 iVal,
[1] int32 iVal2,
[2] bool CS$4$0000)
//Function IL - omitted
} // end of method Test2::Scope
Whenever a C++ variable, allocated on the stack, goes out of scope it gets destructed. Remember that in C++ you can create objects on the stack or on the heap. When you create them on the stack, once execution leaves the scope, they get popped off the stack and gets destroyed.
if (true) {
MyClass stackObj; //created on the stack
MyClass heapObj = new MyClass(); //created on the heap
obj.doSomething();
} //<-- stackObj is destroyed
//heapObj still lives
When C++ objects are created on the heap, they must be explicitly destroyed, otherwise it is a memory leak. No such problem with stack variables though.
In CLR, objects (i.e. reference types) are always created on the managed heap. This is further reinforced by object creation syntax. Consider this code snippet.
MyClass stackObj;
In C++ this would create an instance on MyClass
on the stack and call its default constructor. In C# it would create a reference to class MyClass
that doesn't point to anything. The only way to create an instance of a class is by using new
operator:
MyClass stackObj = new MyClass();
In a way, C# objects are a lot like objects that are created using new
syntax in C++ - they are created on the heap but unlike C++ objects, they are managed by the runtime, so you don't have to worry about destructing them.
Since the objects are always on the heap the fact that object references (i.e. pointers) go out of scope becomes moot. There are more factors involved in determining if an object is to be collected than simply presence of references to the object.
Jon Skeet compared object references in Java to pieces of string that are attached to the balloon, which is the object. Same analogy applies to C# object references. They simply point to a location of the heap that contains the object. Thus, setting it to null has no immediate effect on the object lifetime, the balloon continues to exist, until the GC "pops" it.
Continuing down the balloon analogy, it would seem logical that once the balloon has no strings attached to it, it can be destroyed. In fact this is exactly how reference counted objects work in non-managed languages. Except this approach doesn't work for circular references very well. Imagine two balloons that are attached together by a string but neither balloon has a string to anything else. Under simple ref counting rules, they both continue to exist, even though the whole balloon group is "orphaned".
.NET objects are a lot like helium balloons under a roof. When the roof opens (GC runs) - the unused balloons float away, even though there might be groups of balloons that are tethered together.
.NET GC uses a combination of generational GC and mark and sweep. Generational approach involves the runtime favouring to inspect objects that have been allocated most recently, as they are more likely to be unused and mark and sweep involves runtime going through the whole object graph and working out if there are object groups that are unused. This adequately deals with circular dependency problem.
Also, .NET GC runs on another thread(so called finalizer thread) as it has quite a bit to do and doing that on the main thread would interrupt your program.
If you're using T-SQL
, the only thing wrong with your code is that you used braces {}
instead of parentheses ()
.
PS: Both IDENTITY
and PRIMARY KEY
imply NOT NULL
, so you can omit that if you wish.
Use this query:
UPDATE `table` SET date_date=now();
Sample code can be:
<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("my_db", $con);
mysql_query("UPDATE `table` SET date_date=now()");
mysql_close($con);
?>
this
inside the step callback isn't the element but the object passed to animate()
$('.Count').each(function (_, self) {
jQuery({
Counter: 0
}).animate({
Counter: $(self).text()
}, {
duration: 1000,
easing: 'swing',
step: function () {
$(self).text(Math.ceil(this.Counter));
}
});
});
Another way to do this and keep the references to this
would be
$('.Count').each(function () {
$(this).prop('Counter',0).animate({
Counter: $(this).text()
}, {
duration: 1000,
easing: 'swing',
step: function (now) {
$(this).text(Math.ceil(now));
}
});
});
For me, I had to install Microsoft Access Database Engine 2010 Redistributable and restart my computer.
I've written scripts before that simply use telnet to connect to port 80, then transmit the text:
HTTP/1.0 GET /index.html
followed by two CR/LF sequences.
Provided you get back some form of HTTP response, you can generally assume the site is functioning.

I justed faced very similar problem... BUT RegExp_Count couldn't resolved it. How many times string '16,124,3,3,1,0,' contains ',3,'? As we see 2 times, but RegExp_Count returns just 1. Same thing is with ''bbaaaacc' and when looking in it 'aa' - should be 3 times and RegExp_Count returns just 2.
select REGEXP_COUNT('336,14,3,3,11,0,' , ',3,') from dual;
select REGEXP_COUNT('bbaaaacc' , 'aa') from dual;
I lost some time to research solution on web. Couldn't' find... so i wrote my own function that returns TRUE number of occurance. Hope it will be usefull.
CREATE OR REPLACE FUNCTION EXPRESSION_COUNT( pEXPRESSION VARCHAR2, pPHRASE VARCHAR2 ) RETURN NUMBER AS
vRET NUMBER := 0;
vPHRASE_LENGTH NUMBER := 0;
vCOUNTER NUMBER := 0;
vEXPRESSION VARCHAR2(4000);
vTEMP VARCHAR2(4000);
BEGIN
vEXPRESSION := pEXPRESSION;
vPHRASE_LENGTH := LENGTH( pPHRASE );
LOOP
vCOUNTER := vCOUNTER + 1;
vTEMP := SUBSTR( vEXPRESSION, 1, vPHRASE_LENGTH);
IF (vTEMP = pPHRASE) THEN
vRET := vRET + 1;
END IF;
vEXPRESSION := SUBSTR( vEXPRESSION, 2, LENGTH( vEXPRESSION ) - 1);
EXIT WHEN ( LENGTH( vEXPRESSION ) = 0 ) OR (vEXPRESSION IS NULL);
END LOOP;
RETURN vRET;
END;
You can use
org.apache.commons.lang3.StringUtils.containsIgnoreCase("AbBaCca", "bac");
The Apache Commons library is very useful for this sort of thing. And this particular one may be better than regular expressions as regex is always expensive in terms of performance.
For formatting code in Android Studio on Linux you could instead use Ctrl + Alt + Super + L. You could use this and avoid having to change the system shortcut. (Super key is the Windows icon key besides the Alt key).
It doesn't quite work that way in Python. Python passes references to objects. Inside your function you have an object -- You're free to mutate that object (if possible). However, integers are immutable. One workaround is to pass the integer in a container which can be mutated:
def change(x):
x[0] = 3
x = [1]
change(x)
print x
This is ugly/clumsy at best, but you're not going to do any better in Python. The reason is because in Python, assignment (=
) takes whatever object is the result of the right hand side and binds it to whatever is on the left hand side *(or passes it to the appropriate function).
Understanding this, we can see why there is no way to change the value of an immutable object inside a function -- you can't change any of its attributes because it's immutable, and you can't just assign the "variable" a new value because then you're actually creating a new object (which is distinct from the old one) and giving it the name that the old object had in the local namespace.
Usually the workaround is to simply return the object that you want:
def multiply_by_2(x):
return 2*x
x = 1
x = multiply_by_2(x)
*In the first example case above, 3
actually gets passed to x.__setitem__
.
only working solution for me:
put it on the bottom of build.gradle
com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true
public void Method()
{
if(something)
{
//some code
if(!something2)
{
return;
}
}
// The code i want to go if the second if is true
}
With any server-side language, you will have to emit the POST variables into javascript.
.NET
var my_post_variable = '<%= Request("post_variable") %>';
Just be careful of empty values. If the variable you attempt to emit is actually empty, you will get a javascript syntax error. If you know it's a string, you should wrap it in quotes. If it's an integer, you may want to test to see if it actually exists before writing the line to javascript.
You can use obj.constructor.name to check the "class" of an object https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/name#Function_names_in_classes
For Example
var error = new Error("ValidationError");
console.log(error.constructor.name);
The above line will log "Error" which is the class name of the object. This could be used with any classes in javascript, if the class is not using a property that goes by the name "name"

Joins and unions can be used to combine data from one or more tables. The difference lies in how the data is combined.
In simple terms, joins combine data into new columns. If two tables are joined together, then the data from the first table is shown in one set of column alongside the second table’s column in the same row.
Unions combine data into new rows. If two tables are “unioned” together, then the data from the first table is in one set of rows, and the data from the second table in another set. The rows are in the same result.
When you run the Windows Command Prompt, and type in python
, it starts the Python interpreter.
Typing it again tries to interpret python
as a variable, which doesn't exist and thus won't work:
Microsoft Windows [Version 6.1.7601]

C:\Users\USER>
If you're not doing this from the command line, and instead running the Python interpreter (python.exe or IDLE's shell) directly, you are not in the Windows Command Line, and python
is interpreted as a variable, which you have not defined.

Just to add. If you right-click on an eclipse project and select Properties
, select the Java Build Path
link on the left. Then select the Source
Tab. You'll see a list of all the java source folders. You can even add your own. By default the {project}/src
folder is the classpath folder.
If conditions is the best way to do it. If u want the count use pivot table of buckets. It's the easiest way and the if conditions can go for more than 5-6 buckets too
If you also have SDKMAN...
Somehow SDKMAN was conflicting with my NVM. If you're at your wits end with this and still can't figure it out, I just fixed it by ignoring the "THIS MUST BE AT THE END OF THE FILE..." from SDKMAN and putting the NVM lines after it.
#THIS MUST BE AT THE END OF THE FILE FOR SDKMAN TO WORK!!!
export SDKMAN_DIR="/Users/myname/.sdkman"
[[ -s "/Users/myname/.sdkman/bin/sdkman-init.sh" ]] && source "/Users/myname/.sdkman/bin/sdkman-init.sh"
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
You can adding a +
before the string without using parseInt and parseFloat and radix, Simply
sample:
var votevalue = +$('button').data('votevalue');
alert(typeof(votevalue));
According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:
{% if ( (foo == 'foo' or bar == 'bar') and
(fooo == 'fooo' or baar == 'baar') ) %}
<li>some text</li>
{% endif %}
Edit: Using line_statement_prefix = '#'
* the code would look like this:
# if ( (foo == 'foo' or bar == 'bar') and
(fooo == 'fooo' or baar == 'baar') )
<li>some text</li>
# endif
*Here's an example of how you'd specify the line_statement_prefix
in the Environment
:
from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
loader=PackageLoader('yourapplication', 'templates'),
autoescape=select_autoescape(['html', 'xml']),
line_statement_prefix='#'
)
Or using Flask:
from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

I have encountered this problem:
Possible solution can be found at the link above.
This message indicates that while your subscription may still be valid, the license token Visual Studio uses to keep your subscription up to date hasn’t been refreshed and has gone stale due to one of the following reasons: You have not used Visual Studio or have had no internet connection for an extend period of time.

Thread.sleep() could work in most cases, but usually if you're waiting, you are actually waiting for a particular condition or state to occur. Thread.sleep() does not guarantee that whatever you're waiting for has actually happened.
If you are waiting on a rest request for example maybe it usually return in 5 seconds, but if you set your sleep for 5 seconds the day your request comes back in 10 seconds your test is going to fail.
To remedy this JayWay has a great utility called Awatility which is perfect for ensuring that a specific condition occurs before you move on.
It has a nice fluent api as well
await().until(() ->
{
return yourConditionIsMet();
});
If it were me doing it I'd use sed:
sed -e '$s/$/\n/' -s *.txt > finalfile.txt
In this sed pattern $ has two meanings, firstly it matches the last line number only (as a range of lines to apply a pattern on) and secondly it matches the end of the line in the substitution pattern.
If your version of sed doesn't have -s
(process input files separately) you can do it all as a loop though:
for f in *.txt ; do sed -e '$s/$/\n/' $f ; done > finalfile.txt
There is a method to transport XML-based markup as JSON which allows it to be losslessly converted back to its original form. See http://jsonml.org/.
It's a kind of XSLT of JSON. I hope you find it helpful

From matplotlib 3.1 onwards you may use ax.secondary_xaxis
import numpy as np
import matplotlib.pyplot as plt

y = (np.sin(x)+1.01)*3000
# Define function and its inverse
f = lambda x: 1/(1+x)
g = lambda x: 1/x-1
fig, ax = plt.subplots()
ax.semilogy(x, y, label='DM')
ax2 = ax.secondary_xaxis("top", functions=(f,g))
ax2.set_xlabel("1/(x+1)")
ax.set_xlabel("x")

You have already staged the changes (presumably by running git add
), so in order to get their diff, you need to run:
git diff --cached
(A plain git diff
will only show unstaged changes.)
For example:
/usr/local/ssl/openssl.cnf
This is a local installation. You downloaded and built OpenSSL taking the default prefix
, of you configured with ./config --prefix=/usr/local/ssl
or ./config --openssldir=/usr/local/ssl
.
You will use this if you use the OpenSSL in /usr/local/ssl/bin
. That is, /usr/local/ssl/openssl.cnf
will be used when you issue:
/usr/local/ssl/bin/openssl s_client -connect localhost:443 -tls1 -servername localhost
/usr/lib/ssl/openssl.cnf
This is where Ubuntu places openssl.cnf
for the OpenSSL they provide.
You will use this if you use the OpenSSL in /usr/bin
. That is, /usr/lib/ssl/openssl.cnf
will be used when you issue:
openssl s_client -connect localhost:443 -tls1 -servername localhost
/etc/ssl/openssl.cnf
I don't know when this is used. The stuff in /etc/ssl
is usually certificates and private keys, and it sometimes contains a copy of openssl.cnf
. But I've never seen it used for anything.
Which is the main/correct one that I should use to make changes?
From the sounds of it, you should probably add the engine to /usr/lib/ssl/openssl.cnf
. That ensures most "off the shelf" gear will use the new engine.
After you do that, add it to /usr/local/ssl/openssl.cnf
also because copy/paste is easy.
Here's how to see which openssl.cnf
directory is associated with a OpenSSL installation. The library and programs look for openssl.cnf
in OPENSSLDIR
. OPENSSLDIR
is a configure option, and its set with --openssldir
.
I'm on a MacBook with 3 different OpenSSL's (Apple's, MacPort's and the one I build):
# Apple
$ /usr/bin/openssl version -a | grep OPENSSLDIR
OPENSSLDIR: "/System/Library/OpenSSL"
# MacPorts
$ /opt/local/bin/openssl version -a | grep OPENSSLDIR
OPENSSLDIR: "/opt/local/etc/openssl"
# My build of OpenSSL
$ openssl version -a | grep OPENSSLDIR
OPENSSLDIR: "/usr/local/ssl/darwin"
I have an Ubuntu system and I have installed openssl.
Just bike shedding, but be careful of Ubuntu's version of OpenSSL. It disables TLSv1.1 and TLSv1.2, so you will only have clients capable of older cipher suites; and you will not be able to use newer ciphers like AES/CTR (to replace RC4) and elliptic curve gear (like ECDHE_ECDSA_*
and ECDHE_RSA_*
). See Ubuntu 12.04 LTS: OpenSSL downlevel version is 1.0.0, and does not support TLS 1.2 in Launchpad.
EDIT: Ubuntu enabled TLS 1.1 and TLS 1.2 recently. See Comment 17 on the bug report.

Note that the answers that suggest using unbind()
are now out of date as that method has been deprecated and will be removed in future versions of jQuery.
As of jQuery 3.0, .unbind() has been deprecated. It was superseded by the .off() method since jQuery 1.7, so its use was already discouraged.
Instead, you should now use off()
:
$(window).off('scroll');
Your code has no problem. It does print the way you want. Alternatively, you can do this:
printf("%04x",a);
Adding my answer, because it elaborates the idea that you can SELECT multiple columns from the table from which you subquery.
Here I needed the the most recently cast cote and it's associated information.
I first tried simply to SELECT the max(votedate) along with vote, itemid, userid etc., but while the query would return the max votedate, it would also return the a random row for the other information. Hard to see among a bunch of 1s and 0s.
This worked well:
$query = "
SELECT t1.itemid, t1.itemtext, t2.vote, t2.votedate, t2.userid
FROM
(
SELECT itemid, itemtext FROM oc_item ) t1
LEFT JOIN
(
SELECT vote, votedate, itemid,userid FROM oc_votes
WHERE votedate IN
(select max(votedate) FROM oc_votes group by itemid)
AND userid=:userid) t2
ON (t1.itemid = t2.itemid)
order by itemid ASC
";
The subquery in the WHERE clause WHERE votedate IN (select max(votedate) FROM oc_votes group by itemid) returns one record - the record with the max vote date.
You could call getsockopt just like the following:
int error = 0;
socklen_t len = sizeof (error);
int retval = getsockopt (socket_fd, SOL_SOCKET, SO_ERROR, &error, &len);
To test if the socket is up:
if (retval != 0) {
/* there was a problem getting the error code */
fprintf(stderr, "error getting socket error code: %s\n", strerror(retval));
return;
}
if (error != 0) {
/* socket has a non zero error status */
fprintf(stderr, "socket error: %s\n", strerror(error));
}
string[] str = new string[]{"1","2"};
string[] str = new string[4];
That should do it:
FOR %%a IN (%Svcs%) DO (SC query %%a | FIND /i "RUNNING"
IF ERRORLEVEL 1 SC start %%a)
To add to some of the already excellent answers:
Abstract classes let you provide some degree of implementation, interfaces are pure templates. An interface can only define functionality, it can never implement it.
Any class that implements the interface commits to implementing all the methods it defines or it must be declared abstract.
Interfaces can help to manage the fact that, like Java, PHP does not support multiple inheritance. A PHP class can only extend a single parent. However, you can make a class promise to implement as many interfaces as you want.
type: for each interface it implements, the class takes on the corresponding type. Because any class can implement an interface (or more interfaces), interfaces effectively join types that are otherwise unrelated.
a class can both extend a superclass and implement any number of interfaces:
class SubClass extends ParentClass implements Interface1, Interface2 {
// ...
}
Please explain when I should use an interface and when I should use abstract class?
Use an interface when you need to provide only a template with no implementation what so ever, and you want to make sure any class that implements that interface will have the same methods as any other class that implements it (at least).
Use an abstract class when you want to create a foundation for other objects (a partially built class). The class that extends your abstract class will use some properties or methods defined/implemented:
<?php
// interface
class X implements Y { } // this is saying that "X" agrees to speak language "Y" with your code.
// abstract class
class X extends Y { } // this is saying that "X" is going to complete the partial class "Y".
?>
How I can change my abstract class in to an interface?
Here is a simplified case/example. Take out any implementation details out. For example, change your abstract class from:
abstract class ClassToBuildUpon {
public function doSomething() {
echo 'Did something.';
}
}
to:
interface ClassToBuildUpon {
public function doSomething();
}
I know you asked for Windows but thought I'd add this anyway,in Unix/Linux you could do:
cp `ls -t1 | head -1` /somedir/
Which will list all files in the current directory sorted by modification time and then cp the most recent to /somedir/
with Apache PDFBox it goes like this:
PDDocument document = PDDocument.load(new File("test.pdf"));
if (!document.isEncrypted()) {
PDFTextStripper stripper = new PDFTextStripper();
String text = stripper.getText(document);
System.out.println("Text:" + text);
}
document.close();
this is my way :
<script type="text/javascript">
$(document).ready(function() {
setInterval(function(){currentTime("#idTimeField")}, 500);
});
function currentTime(field) {
var now = new Date();
now = now.getHours() + ':' + now.getMinutes() + ':' + now.getSeconds();
$(field).val(now);
}
it's not maybe the best but do the work :)
When the number being returned by your formula is being formatted as a time, and you want it formatted as a plain number, change the format of the cell to a plain number format: click the cell and then click Format, Number, Normal.
Time values in Google spreadsheet are represented as days and parts of days. For example, 36:00:00 is the formatted representation of the number 1.5 (a day and a half).
Suppose you divide 36:00:00 by 3:00:00, as in your example. Google Spreadsheet performs the calculation 1.5 divided by 0.125, which is 12. The result tells you that you have 12 3-hour intervals in a 36-hour time period. 12, of course, is not a time interval. It is a unitless quantity.
Going the other way, it is possible to format any number as a time. If you format 12 as a time, it's reasonable to expect that you will get 288:00:00. 12 days contain 288 hours.

Two approaches:
Use Calendar
and date(byAdding:to:wrappingComponents:)
. E.g., in Swift 3 and later:
let calendar = Calendar.current
let date = calendar.date(byAdding: .minute, value: 5, to: startDate)
Just use +
operator (see +(_:_:)
) to add a TimeInterval
(i.e. a certain number of seconds). E.g. to add five minutes, you can:
let date = startDate + 5 * 60
(Note, the order is specific here: The date on the left side of the +
and the seconds on the right side.)
You can also use addingTimeInterval
, if you’d prefer:
let date = startDate.addingTimeInterval(5 * 60)
Bottom line, +
/addingTimeInterval
is easiest for simple scenarios, but if you ever want to add larger units (e.g., days, months, etc.), you would likely want to use the calendrical calculations because those adjust for daylight savings, whereas addingTimeInterval
doesn’t.
For Swift 2 renditions, see the previous revision of this answer.
You may use Chocolatey on Windows. It's very easy to use and useful for keeping you updated with other applications too.
Also, you can just simply download the latest version from https://nodejs.org and install it.
Try:
require(Hmisc)
sapply(name, function(x) {
paste(sapply(strsplit(x, ' '), capitalize), collapse=' ')
})
if(TextUtils.isEmpty(firstName.getText().toString()){
firstName.setError("TEXT ERROR HERE");
}
Or you can also use TextInputLayout which has some useful method and some user friendly animation
In azure data studio press "cmd+shift+p" and type "intellisense", then you will see an option to refresh intellisense cache.
No, it's unsafe.
Despite the best efforts of the Hibernate team, you simply cannot rely on automatic updates in production. Write your own patches, review them with DBA, test them, then apply them manually.
Theoretically, if hbm2ddl update worked in development, it should work in production too. But in reality, it's not always the case.
Even if it worked OK, it may be sub-optimal. DBAs are paid that much for a reason.
You're mixing the parts together instead of separating them cleanly.
printf '\e[1;34m%-6s\e[m' "This is text"
Basically, put the fixed stuff in the format and the variable stuff in the parameters.
The ~/Library/Developer/Xcode/iOS DeviceSupport
folder is basically only needed to symbolicate crash logs.
You could completely purge the entire folder. Of course the next time you connect one of your devices, Xcode would redownload the symbol data from the device.
I clean out that folder once a year or so by deleting folders for versions of iOS I no longer support or expect to ever have to symbolicate a crash log for.
This will work for sure, and I actually tried it out:

You don't need FileInputStream to calculate file size, new File(path_to_file).length()
is enough. Or, if you insist, use fileinputstream.getChannel().size()
.
It is a server error, not a client error. If server errors weren't to be returned to the client, there wouldn't have been created an entire status code class for them (i.e. 5xx).
You can't hide the fact that you either made a programming error or some service you rely on is unavailable, and that certainly isn't the client's fault. Returning any other range of code in those cases than the 5xx series would make no sense.
RFC 7231 mentions in section 6.6. Server Error 5xx:
The 5xx (Server Error) class of status code indicates that the server is aware that it has erred or is incapable of performing the requested method.
This is exactly the case. There's nothing "internal" about the code "500 Internal Server Error" in the sense that it shouldn't be exposed to the client.
You should use Array.reduce
for this.
var options = [_x000D_
{ name: 'One', assigned: true }, _x000D_
{ name: 'Two', assigned: false }, _x000D_
{ name: 'Three', assigned: true }, _x000D_
];_x000D_
_x000D_
var reduced = options.reduce(function(filtered, option) {_x000D_
if (option.assigned) {_x000D_
var someNewValue = { name: option.name, newProperty: 'Foo' }_x000D_
filtered.push(someNewValue);_x000D_
}_x000D_
return filtered;_x000D_
}, []);_x000D_
_x000D_
document.getElementById('output').innerHTML = JSON.stringify(reduced);
_x000D_
<h1>Only assigned options</h1>_x000D_
<pre id="output"> </pre>
_x000D_
Alternatively, the reducer can be a pure function, like this
var reduced = options.reduce(function(result, option) {
if (option.assigned) {
return result.concat({
name: option.name,
newProperty: 'Foo'
});
}
return result;
}, []);

You can use math.ceil()

In order to not have the Cannot recover key
exception, I had to apply the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files to the installation of Java that was running my application. Version 8 of those files can be found here or the latest version should be listed on this page. The download includes a file that explains how to apply the policy files.
Since JDK 8u151 it isn't necessary to add policy files. Instead the JCE jurisdiction policy files are controlled by a Security property called crypto.policy
. Setting that to unlimited
with allow unlimited cryptography to be used by the JDK. As the release notes linked to above state, it can be set by Security.setProperty()
or via the java.security
file. The java.security
file could also be appended to by adding -Djava.security.properties=my_security.properties
to the command to start the program as detailed here.
Since JDK 8u161 unlimited cryptography is enabled by default.
These work great for reading left / right "n" characters from a string, but, at least with BBC BASIC, the LEFT$()
and RIGHT$()
functions allowed you to change the left / right "n" characters too...
E.g.:
10 a$="00000"
20 RIGHT$(a$,3)="ABC"
30 PRINT a$
Would produce:
00ABC
Edit : Since writing this, I've come up with my own solution...
def left(s, amount = 1, substring = ""):
if (substring == ""):
return s[:amount]
else:
if (len(substring) > amount):
substring = substring[:amount]
return substring + s[:-amount]
def right(s, amount = 1, substring = ""):
if (substring == ""):
return s[-amount:]
else:
if (len(substring) > amount):
substring = substring[:amount]
return s[:-amount] + substring
To return n characters you'd call
substring = left(string,<n>)
Where defaults to 1 if not supplied. The same is true for right()
To change the left or right n characters of a string you'd call
newstring = left(string,<n>,substring)
This would take the first n characters of substring and overwrite the first n characters of string, returning the result in newstring. The same works for right().

Yes, if bar is not None
is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar:
will execute if bar
is any kind of zero or empty container, or False
.
Many people do use not bar
where they really do mean bar is not None
.
If you can use repeated letters, you can use the *
operator:

Use Enum.TryParse<T>(String, T)
(= .NET 4.0):
StatusEnum myStatus;
Enum.TryParse("Active", out myStatus);
It can be simplified even further with C# 7.0's parameter type inlining:
Enum.TryParse("Active", out StatusEnum myStatus);
The information schema views and pg_typeof() return incomplete type information. Of these answers, psql
gives the most precise type information. (The OP might not need such precise information, but should know the limitations.)
create domain test_domain as varchar(15);
create table test (
test_id test_domain,
test_vc varchar(15),
test_n numeric(15, 3),
big_n bigint,
ip_addr inet
);
Using psql
and \d public.test
correctly shows the use of the data type test_domain
, the length of varchar(n) columns, and the precision and scale of numeric(p, s) columns.
sandbox=# \d public.test Table "public.test" Column | Type | Modifiers ---------+-----------------------+----------- test_id | test_domain | test_vc | character varying(15) | test_n | numeric(15,3) | big_n | bigint | ip_addr | inet |
This query against an information_schema view does not show the use of test_domain
at all. It also doesn't report the details of varchar(n) and numeric(p, s) columns.
select column_name, data_type
from information_schema.columns
where table_catalog = 'sandbox'
and table_schema = 'public'
and table_name = 'test';
column_name | data_type -------------+------------------- test_id | character varying test_vc | character varying test_n | numeric big_n | bigint ip_addr | inet
You might be able to get all that information by joining other information_schema views, or by querying the system tables directly. psql -E
might help with that.
The function pg_typeof()
correctly shows the use of test_domain
, but doesn't report the details of varchar(n) and numeric(p, s) columns.
select pg_typeof(test_id) as test_id,
pg_typeof(test_vc) as test_vc,
pg_typeof(test_n) as test_n,
pg_typeof(big_n) as big_n,
pg_typeof(ip_addr) as ip_addr
from test;
test_id | test_vc | test_n | big_n | ip_addr -------------+-------------------+---------+--------+--------- test_domain | character varying | numeric | bigint | inet

Linux operating system offers different types of shell. Though shells have many commands in common, each type has unique features. Let’s study different kind of mostly used shells.
Sh shell:
Sh shell is also known as Bourne Shell. Sh shell is the first shell developed for Unix computers by Stephen Bourne at AT&T's Bell Labs in 1977. It include many scripting tools.
Bash shell :
Bash shell stands for Bourne Again Shell. Bash shell is the default shell in most linux distribution and substitute for Sh Shell (Sh shell will also run in the Bash shell) . Bash Shell can execute the vast majority of Sh shell scripts without modification and provide commands line editing feature also.
One possible solution to this issue is ng-model
attribute is required to use that directive.
Hence adding in the 'ng-model' attribute can resolve the issue.

One important thing to note, if you have ANSI on sql_mode:
Equivalent to REAL_AS_FLOAT, PIPES_AS_CONCAT, ANSI_QUOTES, IGNORE_SPACE, and (as of MySQL 5.7.5) ONLY_FULL_GROUP_BY.

I +1'ed Sunny's answer, but I wanted to contribute back a few changes I made for my own project in case anyone should find it useful. Basically I've just cleaned up the original code a little so JSLint doesn't complain quite as much, and I made the methods marked as private in the comments actually private. I also added two methods I needed in my own project, namely decodeToHex
and encodeFromHex
.
The code:
var Base64 = (function() {
"use strict";
var _keyStr = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";
var _utf8_encode = function (string) {
var utftext = "", c, n;
string = string.replace(/\r\n/g,"\n");
for (n = 0; n < string.length; n++) {
c = string.charCodeAt(n);
if (c < 128) {
utftext += String.fromCharCode(c);
} else if((c > 127) && (c < 2048)) {
utftext += String.fromCharCode((c >> 6) | 192);
utftext += String.fromCharCode((c & 63) | 128);
} else {
utftext += String.fromCharCode((c >> 12) | 224);
utftext += String.fromCharCode(((c >> 6) & 63) | 128);
utftext += String.fromCharCode((c & 63) | 128);
}
}
return utftext;
};
var _utf8_decode = function (utftext) {
var string = "", i = 0, c = 0, c1 = 0, c2 = 0;
while ( i < utftext.length ) {
c = utftext.charCodeAt(i);
if (c < 128) {
string += String.fromCharCode(c);
i++;
} else if((c > 191) && (c < 224)) {
c1 = utftext.charCodeAt(i+1);
string += String.fromCharCode(((c & 31) << 6) | (c1 & 63));
i += 2;
} else {
c1 = utftext.charCodeAt(i+1);
c2 = utftext.charCodeAt(i+2);
string += String.fromCharCode(((c & 15) << 12) | ((c1 & 63) << 6) | (c2 & 63));
i += 3;
}
}
return string;

}());
Instead of - fd.append( 'userfile', $('#userfile')[0].files[0]);

Tomcat can tell you in several ways. Here's the easiest:
$ /path/to/catalina.sh version
Using CATALINA_BASE: /usr/local/apache-tomcat-7.0.29
Using CATALINA_HOME: /usr/local/apache-tomcat-7.0.29
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-7.0.29/temp
Using JRE_HOME: /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home
Using CLASSPATH: /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar
Server version: Apache Tomcat/7.0.29
Server built: Jul 3 2012 11:31:52
Server number: 7.0.29.0
OS Name: Mac OS X
OS Version: 10.7.4
Architecture: x86_64
JVM Version: 1.6.0_33-b03-424-11M3720
JVM Vendor: Apple Inc.
If you don't know where catalina.sh
is (or it never gets called), you can usually find it via ps
:
$ ps aux | grep catalina
chris 930 0.0 3.1 2987336 258328 s000 S Wed01PM 2:29.43 /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Dnop -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.library.path=/usr/local/apache-tomcat-7.0.29/lib -Djava.endorsed.dirs=/usr/local/apache-tomcat-7.0.29/endorsed -classpath /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar -Dcatalina.base=/Users/chris/blah/blah -Dcatalina.home=/usr/local/apache-tomcat-7.0.29 -Djava.io.tmpdir=/Users/chris/blah/blah/temp org.apache.catalina.startup.Bootstrap start
From the ps
output, you can see both catalina.home
and catalina.base
. catalina.home
is where the Tomcat base files are installed, and catalina.base
is where the running configuration of Tomcat exists. These are often set to the same value unless you have configured your Tomcat for multiple (configuration) instances to be launched from a single Tomcat base install.
You can also interrogate the JVM directly if you can't find it in a ps
listing:
$ jinfo -sysprops 930 | grep catalina
Attaching to process ID 930, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 20.8-b03-424
catalina.base = /Users/chris/blah/blah
[...]
catalina.home = /usr/local/apache-tomcat-7.0.29
If you can't manage that, you can always try to write a JSP that dumps the values of the two system properties catalina.home
and catalina.base

Floats have less precision than doubles. Although you already know, read What WE Should Know About Floating-Point Arithmetic for better understanding.
That will open a new window, not tab (with JavaScript, but quite laconically):
<a href="print.html"
onclick="window.open('print.html',
'newwindow',
'width=300,height=250');
return false;"
>Print</a>
The issue is that you're not saving the mysqli connection. Change your connect to:
$aVar = mysqli_connect('localhost','tdoylex1_dork','dorkk','tdoylex1_dork');
And then include it in your query:
$query1 = mysqli_query($aVar, "SELECT name1 FROM users
ORDER BY RAND()
LIMIT 1");
$aName1 = mysqli_fetch_assoc($query1);
$name1 = $aName1['name1'];
Also don't forget to enclose your connections variables as strings as I have above. This is what's causing the error but you're using the function wrong, mysqli_query returns a query object but to get the data out of this you need to use something like mysqli_fetch_assoc http://php.net/manual/en/mysqli-result.fetch-assoc.php to actually get the data out into a variable as I have above.
I have found that 6 decimal places is sometimes required (at least in Chrome) for the 1/3 to return a perfect result.
E.g., 1140px / 3 = 380px
If you had 3 elements within the 1140 container, they would need to have a width set to 33.333333% before Chrome's inspector tool shows that they are at 380px. Any less amount of decimal places, and Chrome returns a lesser width of 379.XXXpx
Please try to remove the preceeding spaces before EOF
:-
/var/mail -s "$SUBJECT" "$EMAIL" <<-EOF
Using <tab>
instead of <spaces>
for ident AND using <<-EOF works fine.
The "-"
removes the <tabs>
, not <spaces>
, but at least this works.
Try this its working for me.
private static async Task<object> Upload(string actionUrl)
{
Image newImage = Image.FromFile(@"Absolute Path of image");
ImageConverter _imageConverter = new ImageConverter();
byte[] paramFileStream= (byte[])_imageConverter.ConvertTo(newImage, typeof(byte[]));
var formContent = new MultipartFormDataContent
{
// Send form text values here
{new StringContent("value1"),"key1"},
{new StringContent("value2"),"key2" },
// Send Image Here
{new StreamContent(new MemoryStream(paramFileStream)),"imagekey","filename.jpg"}
};
var myHttpClient = new HttpClient();
var response = await myHttpClient.PostAsync(actionUrl.ToString(), formContent);
string stringContent = await response.Content.ReadAsStringAsync();
return response;
}

Assuming you are a PyCharm User, its pretty easy to install Flask This will help users without shell pip access also.

Now back to pip, it will show related packages of flask,
Voila!!!
$('input#edit-keys-1').blur(function(){
tmpval = $(this).val();

} else {
$(this).addClass('not-empty');
$(this).removeClass('empty');
}
});
in jQuery. I added a class and styled with css.
.empty { background:none; }
