include the package name with class. It will remove your name. I also got the same issue but adding the package name with class fixed this issue.
Ideally you would use an ashx to send XML although I do allow code in an ASPX to intercept normal execution.
Response.Clear()
I don't use this if you not sure you've dumped anything in the response already the go find it and get rid of it.
Response.ContentType = "text/xml"
Definitely, a common client will not accept the content as XML without this content type present.
Response.Charset = "UTF-8";
Let the response class handle building the content type header properly. Use UTF-8 unless you have a really, really good reason not to.
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetAllowResponseInBrowserHistory(true);
If you don't send cache headers some browsers (namely IE) will cache the response, subsequent requests will not necessarily come to the server. You also need to AllowResponseInBrowser if you want this to work over HTTPS (due to yet another bug in IE).
To send content of an XmlDocument simply use:
dom.Save(Response.OutputStream);
dom.Save(Response.Output);
Just be sure the encodings match, (another good reason to use UTF-8).
The XmlDocument
object will automatically adjust its embedded encoding="..."
encoding to that of the Response
(e.g. UTF-8
)
Response.End()
If you really have to in an ASPX but its a bit drastic, in an ASHX don't do it.
I propose use StringBuilder
string s1 = "'99024','99050','99070','99143','99173','99191','99201','99202','99203','99204','99211','99212','99213','99214','99215','99217','99218','99219','99221','99222','99231','99232','99238','99239','99356','99357','99371','99374','99381','99382','99383','99384','99385','99386','99391','99392'";
var stringBuilder = new StringBuilder();
foreach (var s in s1.Split(','))
{
stringBuilder.Append(s).Append(",").AppendLine();
}
Console.WriteLine(stringBuilder);
Have you tried to edit to see what's wrong (I had the wrong image location)
kubectl edit pods arix-3-yjq9w
or even delete your pod?
kubectl delete arix-3-yjq9w
Your problem can easily be solved by converting it to the object first. After it is converted to object, just use "astype" to convert it to str.
obj = lambda x:x[1:]
df['id']=df['id'].apply(obj).astype('str')

Re: the dead "Turning Vim Into A Modern Python IDE" link, back in 2013 I saved a copy, that I converted to a HTML page as well as a PDF copy:

Alternatively, just GROUP BY
the hour and day:
SELECT CAST(Startdate as DATE) as 'StartDate',
CAST(DATEPART(Hour, StartDate) as varchar) + ':00' as 'Hour',
COUNT(*) as 'Ct'
FROM #Events
GROUP BY CAST(Startdate as DATE), DATEPART(Hour, StartDate)
ORDER BY CAST(Startdate as DATE) ASC
output:

For some looking for a solution to this problem, the root of the issue may be where you are setting your list views adapter. After you set the adapter on the listview, it resets the scroll position. Just something to consider. I moved setting the adapter into my onCreateView after we grab the reference to the listview, and it solved the problem for me. =)
This is the way i did it, with a button to add each select tag.
$(document).on("click","#button",function() {
$('#id_table_AddTransactions').append('<option></option>')
}
I can suggest you a javascript oriented approach which makes it easy to work with javascript files in your project.
Create a javascript section in your jinja template file and place all variables you want to use in your javascript files in a window object:
Start.html
...
{% block scripts %}
<script type="text/javascript">
window.appConfig = {
debug: {% if env == 'development' %}true{% else %}false{% endif %},
facebook_app_id: {{ facebook_app_id }},
accountkit_api_version: '{{ accountkit_api_version }}',
csrf_token: '{{ csrf_token }}'
}
</script>
<script type="text/javascript" src="{{ url_for('static', filename='app.js') }}"></script>
{% endblock %}
Jinja will replace values and our appConfig object will be reachable from our other script files:
App.js
var AccountKit_OnInteractive = function(){
AccountKit.init({
appId: appConfig.facebook_app_id,
debug: appConfig.debug,
state: appConfig.csrf_token,
version: appConfig.accountkit_api_version
})
}
I have seperated javascript code from html documents with this way which is easier to manage and seo friendly.
I've solved this error by this way.
$ch = curl_init ();
curl_setopt ( $ch, CURLOPT_URL, 'http://www.someurl/' );
curl_setopt ( $ch, CURLOPT_TIMEOUT, 30);
ob_start();
$response = curl_exec ( $ch );
$data = ob_get_clean();
if(curl_getinfo($ch, CURLINFO_HTTP_CODE) == 200 ) success;
Error still occurs, but I can handle response data in variable.
You could do the following:
.interrupt
the working threads if they wait for data in some blocking call)writeBatch
in your case) to finish, by calling the Thread.join()
method on the working threads.Some sketchy code:
static volatile boolean keepRunning = true;
In run() you change to
for (int i = 0; i < N && keepRunning; ++i)
writeBatch(pw, i);
In main() you add:
final Thread mainThread = Thread.currentThread();
Runtime.getRuntime().addShutdownHook(new Thread() {
public void run() {
keepRunning = false;
mainThread.join();
}
});
That's roughly how I do a graceful "reject all clients upon hitting Control-C" in terminal.
From the docs:
When the virtual machine begins its shutdown sequence it will start all registered shutdown hooks in some unspecified order and let them run concurrently. When all the hooks have finished it will then run all uninvoked finalizers if finalization-on-exit has been enabled. Finally, the virtual machine will halt.
That is, a shutdown hook keeps the JVM running until the hook has terminated (returned from the run()-method.
Received this same error on SQL Server 2017 trying to link to Oracle 12c. We were able to use Oracle's SQL Developer to connect to the source database, but the linked server kept throwing the 7302 error.
In the end, we stopped all SQL Services, then re-installed the ODAC components. Started the SQL Services back up and voila!
The following doesn't solve the OP's problem, but the title and error is exactly what I faced.
If your project has a setup.py
script in it, you can install that package you are in, with python3 -m pip install -e .
or python3 setup.py install
or python3 setup.py develop
, and this package will be installed, but still editable (so changes to the code will be seen when importing the package). If it doesn't have a setup.py
, make sense of it.
one.py
:def function():
print("output")
two.py
:#!/usr/bin/env python3
import one
one.function()
chmod +x two.py # To allow execution of the python file
./two.py # Only works if you have a python shebang
Command line output: output
In the case of OP with 2 test files, modifying them to work is probably fine. However, in other real scenarios, the methods listed in the other answers is probably not recommended. They require you to modify the python code or restrict your flexibility (running the python file from a specific directory) and generally introduce annoyances. What if you've just cloned a project, and this happens? It probably already works for other people, and making code changes is unnecessary. The chosen answer also wants people to run a script from a specific folder to make it work. This can be a source of long term annoyance, which is never good. It also suggests adding your specific python folder to PATH (can be done through python or command line). Again, what happens if you rename or move the folder in a few months? You have to hunt down this page again, and eventually discover you need to set the path (and that you did exactly this a few months ago), and that you simply need to update a path (sure you could use sys.path and programmatically set it, but this can be flaky still). Many sources of great annoyance.
from subprocess import Popen, PIPE
from tempfile import SpooledTemporaryFile as tempfile
f = tempfile()

f.close()
None of the current answers worked for me. I found a solution here.
The issue was that my previous credentials were cached by the Windows OS for the TFS server. While some people might have had success wiping out the AppData temp folders, that is not required.
You need to update the credentials through Control Panel on the Windows OS.
For me on Windows 10: Close VS. Go to Control Panel (with small icon view)-->User Accounts-->Manage your credentials (on the left column)-->Select "Windows Credentials"-->Scroll down to the "Generic Credentials" section and look for your TFS server connection. Expand the pull down and click "Edit". Enter in new network password. Reopen VS and everything should work again.
I was experiencing the white line to the right on my iPad as well in horizontal position only. I was using a fixed-position div with a background set to 960px wide and z-index of -999. This particular div only shows up on an iPad due to a media query. Content was then placed into a 960px wide div wrapper. The answers provided on this page were not helping in my case. To fix the white stripe issue I changed the width of the content wrapper to 958px. Voilá. No more white right white stripe on the iPad in horizontal position.
WebSockets is protocol that relies on TCP streamed connection. Although WebSockets is Message based protocol.
If you want to implement your own protocol then I recommend to use latest and stable specification (for 18/04/12) RFC 6455. This specification contains all necessary information regarding handshake and framing. As well most of description on scenarios of behaving from browser side as well as from server side. It is highly recommended to follow what recommendations tells regarding server side during implementing of your code.
In few words, I would describe working with WebSockets like this:
Create server Socket (System.Net.Sockets) bind it to specific port, and keep listening with asynchronous accepting of connections. Something like that:
Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP); serverSocket.Bind(new IPEndPoint(IPAddress.Any, 8080)); serverSocket.Listen(128); serverSocket.BeginAccept(null, 0, OnAccept, null);
You should have accepting function "OnAccept" that will implement handshake. In future it has to be in another thread if system is meant to handle huge amount of connections per second.
private void OnAccept(IAsyncResult result) { try { Socket client = null; if (serverSocket != null && serverSocket.IsBound) { client = serverSocket.EndAccept(result); } if (client != null) { /* Handshaking and managing ClientSocket */ } } catch(SocketException exception) { } finally { if (serverSocket != null && serverSocket.IsBound) { serverSocket.BeginAccept(null, 0, OnAccept, null); } } }
After connection established, you have to do handshake. Based on specification 1.3 Opening Handshake, after connection established you will receive basic HTTP request with some information. Example:
GET /chat HTTP/1.1 Host: server.example.com Upgrade: websocket Connection: Upgrade Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ== Origin: http://example.com Sec-WebSocket-Protocol: chat, superchat Sec-WebSocket-Version: 13
This example is based on version of protocol 13. Bear in mind that older versions have some differences but mostly latest versions are cross-compatible. Different browsers may send you some additional data. For example Browser and OS details, cache and others.
Based on provided handshake details, you have to generate answer lines, they are mostly same, but will contain Accpet-Key, that is based on provided Sec-WebSocket-Key. In specification 1.3 it is described clearly how to generate response key. Here is my function I've been using for V13:
static private string guid = "258EAFA5-E914-47DA-95CA-C5AB0DC85B11"; private string AcceptKey(ref string key) { string longKey = key + guid; SHA1 sha1 = SHA1CryptoServiceProvider.Create(); byte[] hashBytes = sha1.ComputeHash(System.Text.Encoding.ASCII.GetBytes(longKey)); return Convert.ToBase64String(hashBytes); }
Handshake answer looks like that:
HTTP/1.1 101 Switching Protocols Upgrade: websocket Connection: Upgrade Sec-WebSocket-Accept: s3pPLMBiTxaQ9kYGzzhZRbK+xOo=
But accept key have to be the generated one based on provided key from client and method AcceptKey I provided before. As well, make sure after last character of accept key you put two new lines "\r\n\r\n".
Implementing own WebSockets protocol definitely have some benefits and great experience you get as well as control over protocol it self. But you have to spend some time doing it, and make sure that implementation is highly reliable.
In same time you might have a look in ready to use solutions that google (again) have enough.
That's basically it. These are the methods I use to convert to and from Unix epoch time:
public static DateTime ConvertFromUnixTimestamp(double timestamp)
{
DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
return origin.AddSeconds(timestamp);
}
public static double ConvertToUnixTimestamp(DateTime date)
{
DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
TimeSpan diff = date.ToUniversalTime() - origin;
return Math.Floor(diff.TotalSeconds);
}
Update: As of .Net Core 2.1 and .Net Standard 2.1 a DateTime equal to the Unix Epoch can be obtained from the static DateTime.UnixEpoch
.
In PostgreSQL this works for me:
select count(count.counts)
from
(select count(*) as counts
from table
group by concept) as count;
There are three ways to keep the model in sync.
Delete the modified tables from the designer, and drag them back onto the designer surface from the Database Explorer. I have found that, for this to work reliably, you have to:
a. Refresh the database schema in the Database Explorer (right-click, refresh)
b. Save the designer after deleting the tables
c. Save again after dragging the tables back.
Note though that if you have modified any properties (for instance, turning off the child property of an association), this will obviously lose those modifications — you'll have to make them again.
Use SQLMetal to regenerate the schema from your database. I have seen a number of blog posts that show how to script this.
Make changes directly in the Properties pane of the DBML. This works for simple changes, like allowing nulls on a field.
The DBML designer is not installed by default in Visual Studio 2015, 2017 or 2019. You will have to close VS, start the VS installer and modify your installation. The LINQ to SQL tools is the feature you must install. For VS 2017/2019, you can find it under Individual Components > Code Tools.
There is another solution for this.
Consider the quotes as part of the fields delimiter, by editing the fmt file.
You can check this out for more information:
An extract of the link above:
The only way to remove the quotation marks would be to modify the column delimiters specified during the import operation. The only drawback here is that if you inspect the data to be inserted, you will very quickly realize that the column delimiters are different for each column (Delimiters highlighted above).
So to specify different column delimiters for each column, you would need to use a format file if you plan to use Bulk Insert or BCP. If you generate a format file for the above table structure, it would be as follows:
9.0
3
1 SQLCHAR 0 5 "\t" 1 FName SQL_Latin1_General_CP1_CI_AS
2 SQLCHAR 0 5 "\t" 2 LName SQL_Latin1_General_CP1_CI_AS
3 SQLCHAR 0 50 "\r\n" 3 Company SQL_Latin1_General_CP1_CI_AS
Modify the format file to represent the correct column delimiters for each column. The new format file to be used will look like this:
9.0
4
1 SQLCHAR 0 0 "\"" 0 FIRST_QUOTE SQL_Latin1_General_CP1_CI_AS
2 SQLCHAR 0 5 "\",\"" 1 FNAME SQL_Latin1_General_CP1_CI_AS
3 SQLCHAR 0 5 "\",\"" 2 LNAME SQL_Latin1_General_CP1_CI_AS
4 SQLCHAR 0 50 "\"\r\n" 3 COMPANY SQL_Latin1_General_CP1_CI_AS
I'm surprised that the answers here got so many upvotes when none of them really answer the question. Here's how to make sure that ONLY LATIN characters are in a given string.
const hasOnlyLetters = !!value.match(/^[a-z]*$/i);
The !!
takes transforms something that's not boolean into a boolean value. (It's exactly the same as applying a !
twice, and in fact you can use as many !
as you'd like to toggle the truthiness multiple times.)
As for the RegEx, here's the breakdown.
/.../i
The delimiter is a /
and the i
means to assess the statement in a case-insensitive fashion.^...$
The ^
means to look at the very beginning of a string. The $
means to look at the end of the string, and when used together, it means to consider the entire string. You can add more to the RegEx outside of these boundaries for things like appending/prepending a required suffix or prefix.[a-z]*
This part says to look for all lowercase letters. (The case-insensitive modifier means that we don't need to look at uppercase letters, too.) The *
at the end says that we should match whats in the brackets any number of times. That way "abc" will match instead of just "a" or "b", and so forth.location / {
is the most general location (with location {
). It will match anything, AFAIU. I doubt that it would be useful to have location / { index index.html; }
because of a lot of duplicate content for every subdirectory of your site.
The approach with
try_files $uri $uri/index.html index.html;
is bad, as mentioned in a comment above, because it returns index.html
for pages which should not exist on your site (any possible $uri
will end up in that).
Also, as mentioned in an answer above, there is an internal redirect in the last argument of try_files
.
Your approach
location = / { index index.html;
is also bad, since index
makes an internal redirect too. In case you want that, you should be able to handle that in a specific location
. Create e.g.
location = /index.html {
as was proposed here. But then you will have a working link http://example.org/index.html
, which may be not desired. Another variant, which I use, is:
root /www/my-root;
# http://example.org
# = means exact location
location = / {
try_files /index.html =404;
}
# disable http://example.org/index as a duplicate content
location = /index { return 404; }
# This is a general location.
# (e.g. http://example.org/contacts <- contacts.html)
location / {
# use fastcgi or whatever you need here
# return 404 if doesn't exist
try_files $uri.html =404;
}
P.S. It's extremely easy to debug nginx (if your binary allows that). Just add into the server {
block:
error_log /var/log/nginx/debug.log debug;
and see there all internal redirects etc.
There's no fixed time for retransmission. Simple implementations estimate the RTT (round-trip-time) and if no ACK to send data has been received in 2x that time then they re-send.
They then double the wait-time and re-send once more if again there is no reply. Rinse. Repeat.
More sophisticated systems make better estimates of how long it should take for the ACK as well as guesses about exactly which data has been lost.
The bottom-line is that there is no hard-and-fast rule about exactly when to retransmit. It's up to the implementation. All retransmissions are triggered solely by the sender based on lack of response from the receiver.
TCP never drops data so no, there is no way to indicate a server should forget about some segment.
One more way to Bind ViewModel Boolean Value (IsButtonVisible) with xaml Control Visibility Property. No coding, No converting, just styling.
<Style TargetType={x:Type Button} x:Key="HideShow">
<Style.Triggers>
<DataTrigger Binding="{Binding IsButtonVisible}" Value="False">
<Setter Property="Visibility" Value="Hidden"/>
</DataTrigger>
</Style.Triggers>
</Style>
<Button Style="{StaticResource HideShow}">Hello</Button>
Open your.gitconfig file to add the longpaths property. So it will look like the following:
[core]
symlinks = false
autocrlf = true
longpaths = true
Expanding on the notes from Adel Mourad and Dan Hunex, I amended the code to provide an example that only accepts values that do not match the given value.
I also found that I didn't need the JavaScript.
I added the following class to my Models folder:
public class RequiredIfNotAttribute : ValidationAttribute, IClientValidatable
{
private String PropertyName { get; set; }
private Object InvalidValue { get; set; }
private readonly RequiredAttribute _innerAttribute;
public RequiredIfNotAttribute(String propertyName, Object invalidValue)
{
PropertyName = propertyName;
InvalidValue = invalidValue;
_innerAttribute = new RequiredAttribute();
}
protected override ValidationResult IsValid(object value, ValidationContext context)
{
var dependentValue = context.ObjectInstance.GetType().GetProperty(PropertyName).GetValue(context.ObjectInstance, null);
if (dependentValue.ToString() != InvalidValue.ToString())
{
if (!_innerAttribute.IsValid(value))
{
return new ValidationResult(FormatErrorMessage(context.DisplayName), new[] { context.MemberName });
}
}
return ValidationResult.Success;
}
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
{
var rule = new ModelClientValidationRule
{
ErrorMessage = ErrorMessageString,
ValidationType = "requiredifnot",
};
rule.ValidationParameters["dependentproperty"] = (context as ViewContext).ViewData.TemplateInfo.GetFullHtmlFieldId(PropertyName);
rule.ValidationParameters["invalidvalue"] = InvalidValue is bool ? InvalidValue.ToString().ToLower() : InvalidValue;
yield return rule;
}
I didn't need to make any changes to my view, but did make a change to the properties of my model:
[RequiredIfNot("Id", 0, ErrorMessage = "Please select a Source")]
public string TemplateGTSource { get; set; }
public string TemplateGTMedium
{
get
{
return "Email";
}
}
[RequiredIfNot("Id", 0, ErrorMessage = "Please enter a Campaign")]
public string TemplateGTCampaign { get; set; }
[RequiredIfNot("Id", 0, ErrorMessage = "Please enter a Term")]
public string TemplateGTTerm { get; set; }
Hope this helps!
I had to combine Maiasaura and Svun answers to get it to work: using setwd and escaping all the slashes and spaces.
setwd('C:\\Users\\firstname\ lastname\\Desktop\\folder1\\folder2\\folder3')
data = read.csv("file.csv")
data
This solved the issue for me.
this works fine, but file name does not display anymore.
$(document).ready(function(){ $("img.attach2").click(function(){ $("input.attach1").click(); return false; }); });

Apart of directly writing HTML on the PrintWriter obtained from the response (which is the standard way of outputting HTML from a Servlet), you can also include an HTML fragment contained in an external file by using a RequestDispatcher:
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("HTML from an external file:");
request.getRequestDispatcher("/pathToFile/fragment.html")
.include(request, response);
out.close();
}
I added the following job to crontab. It is hacky but i think should work.
*/5 * * * * service ntpd stop && ntpdate pool.ntp.org && service ntpd start
It stops ntpd service updates from service and starts ntpd again
You could return to the previous page by using ViewBag.ReturnUrl
property.
For me, none of the above did directly work for me. What I did is the following:
Additionally to @Rodrigo Villalba Zayas answer up there I added
implements InitializingBean
to the class
and implemented the method
@Override
public void afterPropertiesSet() {
String path = env.getProperty("userBucket.path");
}
So that will look like
import org.springframework.core.env.Environment;
public class xyz implements InitializingBean {
@Autowired
private Environment env;
private String path;
....
@Override
public void afterPropertiesSet() {
path = env.getProperty("userBucket.path");
}
public void method() {
System.out.println("Path: " + path);
}
}

You could do this using SUMIF
. This allows you to SUM a value in a cell IF a value in another cell meets the specified criteria. Here's an example:
- A B
1 100 YES
2 100 YES
3 100 NO
Using the formula: =SUMIF(B1:B3, "YES", A1:A3)
, you will get the result of 200
.

target_link_libraries(target_name pthread)
Solution 2: using CMake find_package
find_package(Threads REQUIRED) # this will generate the flag for CMAKE_THREAD_LIBS_INIT
add_executable(...)
target_include_directories(...)
target_link_libraries(target_name ${CMAKE_THREAD_LIBS_INIT})
Solution 3: Change CMake flags
# e.g. with C++ 17, change to other version if you need
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++17 -pthread")
In general your .h contains the class defition, which is all your data and all your method declarations. Like this in your case:
A2DD.h:
class A2DD
{
private:
int gx;
int gy;
public:
A2DD(int x,int y);
int getSum();
};
And then your .cpp contains the implementations of the methods like this:
A2DD.cpp:
A2DD::A2DD(int x,int y)
{
gx = x;
gy = y;
}
int A2DD::getSum()
{
return gx + gy;
}
You can get around this by using a traits class:
It requires you set up a specialsed traits class for each actuall class you use.
template<typename SubClass>
class SubClass_traits
{};
template<typename Subclass>
class A {
public:
void action(typename SubClass_traits<Subclass>::mytype var)
{
(static_cast<Subclass*>(this))->do_action(var);
}
};
// Definitions for B
class B; // Forward declare
template<> // Define traits for B. So other classes can use it.
class SubClass_traits<B>
{
public:
typedef int mytype;
};
// Define B
class B : public A<B>
{
// Define mytype in terms of the traits type.
typedef SubClass_traits<B>::mytype mytype;
public:
B() {}
void do_action(mytype var) {
// Do stuff
}
};
int main(int argc, char** argv)
{
B myInstance;
return 0;
}
If you are using a custom header view:
class YourCustomHeaderFooterView: UITableViewHeaderFooterView {
override func awakeFromNib() {
super.awakeFromNib()
self.contentView.backgroundColor = .white //Or any color you want
}
}
I cannot see why there is a recommendation to use scanf()
here. scanf()
is safe only if you add restriction parameters to the format string - such as %64s
or so.
A much better way is to use char * fgets ( char * str, int num, FILE * stream );
.
int main()
{
char data[64];
if (fgets(data, sizeof data, stdin)) {
// input has worked, do something with data
}
}
(untested)
You can use the following code :
<!DOCTYPE html>
<html>
<body onLoad="triggerJS();">
<script>
function triggerJS(){
location.replace("http://www.google.com");
/*
location.assign("New_WebSite_Url");
//Use assign() instead of replace if you want to have the first page in the history (i.e if you want the user to be able to navigate back when New_WebSite_Url is loaded)
*/
}
</script>
</body>
</html>
There are a couple of options:
Just after initialising DataTables, remove the sorting classes on the TD element in the TBODY.
Disable the sorting classes using http://datatables.net/ref#bSortClasses . Problem with this is that it will disable the sort classes for user sort requests - which might or might not be what you want.
Have your server output the table in your required sort order, and don't apply a default sort on the table (aaSorting:[]
).
I had the same exception. The problem was, that I used the annotation
@RepositoryRestController
instead of
@RestController
Based on the @MixerOID response, here is my final solution as a component (maybe I create a library). I also support FormArray's:
import {Component, ElementRef, Input, OnInit} from '@angular/core';
import {FormArray, FormGroup, ValidationErrors} from '@angular/forms';
import {TranslateService} from '@ngx-translate/core';
interface AllValidationErrors {
controlName: string;
errorName: string;
errorValue: any;
}
@Component({
selector: 'app-form-errors',
templateUrl: './form-errors.component.html',
styleUrls: ['./form-errors.component.scss']
})
export class FormErrorsComponent implements OnInit {
@Input() form: FormGroup;
@Input() formRef: ElementRef;
@Input() messages: Array<any>;
private errors: AllValidationErrors[];
constructor(
private translateService: TranslateService
) {
this.errors = [];
this.messages = [];
}
ngOnInit() {
this.form.valueChanges.subscribe(() => {
this.errors = [];
this.calculateErrors(this.form);
});
this.calculateErrors(this.form);
}
calculateErrors(form: FormGroup | FormArray) {
Object.keys(form.controls).forEach(field => {
const control = form.get(field);
if (control instanceof FormGroup || control instanceof FormArray) {
this.errors = this.errors.concat(this.calculateErrors(control));
return;
}
const controlErrors: ValidationErrors = control.errors;
if (controlErrors !== null) {
Object.keys(controlErrors).forEach(keyError => {
this.errors.push({
controlName: field,
errorName: keyError,
errorValue: controlErrors[keyError]
});
});
}
});
// This removes duplicates
this.errors = this.errors.filter((error, index, self) => self.findIndex(t => {
return t.controlName === error.controlName && t.errorName === error.errorName;
}) === index);
return this.errors;
}
getErrorMessage(error) {
switch (error.errorName) {
case 'required':
return this.translateService.instant('mustFill') + ' ' + this.messages[error.controlName];
default:
return 'unknown error ' + error.errorName;
}
}
}
And the HTML:
<div *ngIf="formRef.submitted">
<div *ngFor="let error of errors" class="text-danger">
{{getErrorMessage(error)}}
</div>
</div>
Usage:
<app-form-errors [form]="languageForm"
[formRef]="formRef"
[messages]="{language: 'Language'}">
</app-form-errors>
There is a much easier way to run PHP, no configuration needed:
Ctrl+Alt+N
F1
and then select/type Run Code
, Run Code
in editor context menuRun Code
button in editor title menuRun Code
button in context menu of file explorerBesides, you could select part of the PHP code and run the code snippet. Very convenient!
This worked for me with Ubuntu 16.04
$ LIBRARY_PATH=/usr/lib/x86_64-linux-gnu
$ export LIBRARY_PATH
Handle the Worksheet_Change
event or the Workbook_SheetChange
event.
The event handlers take an argument "Target As Range", so you can check if the range that's changing includes the cell you're interested in.
Yes, it could be with the actual encoding of the file, probably unicode. Try UTF-8 as that is the most common form of unicode encoding. Otherwise if the file ASCII then standard ASCII encoding should work.
I had to:
Delete node_modules
Uninstall/reinstall node
npm install [email protected]
worked fine after forcing it to the right sass version, according to the version said to be working with the right node.
NodeJS Minimum node-sass version Node Module
Node 12 4.12+ 72
Node 11 4.10+ 67
Node 10 4.9+ 64
Node 8 4.5.3+ 57
There was lots of other errors that seemed to be caused by the wrong sass version defined.
Since this is the top result on Google, I will post here after failing to find a solution for my problem. If you are looking to format the display value of a float object and have it remain a float - not a string, you can use this solution:
Create a new class that modifies the way that float values are displayed.
from builtins import float
class FormattedFloat(float):
def __str__(self):
return "{:.10f}".format(self).rstrip('0')
You can modify the precision yourself by changing the integer values in {:f}
I am using an ImageView in an RelativeLayout that overlays with my normal layout. No code required. It sizes the image to the full height of the screen (or any other layout you use) and then crops the picture left and right to fit the width. In my case, if the user turns the screen, the picture may be a tiny bit too small. Therefore I use match_parent, which will make the image stretch in width if too small.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/main_backgroundImage"
android:layout_width="match_parent"
//comment: Stretches picture in the width if too small. Use "wrap_content" does not stretch, but leaves space
android:layout_height="match_parent"
//in my case I always want the height filled
android:layout_alignParentTop="true"
android:scaleType="centerCrop"
//will crop picture left and right, so it fits in height and keeps aspect ratio
android:contentDescription="@string/image"
android:src="@drawable/your_image" />
<LinearLayout
android:id="@+id/main_root"
android:layout_width="match_parent"
android:layout_height="match_parent"

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)
It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.
Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)
you will see a Words equivalent of the numeric value.

That's because you shouldn't do it (at least with an immutable list). If you really really need to append an element to the end of a data structure and this data structure really really needs to be a list and this list really really has to be immutable then do eiher this:
(4 :: List(1,2,3).reverse).reverse
or that:
List(1,2,3) ::: List(4)
Try this:
$("button").click(function () {
$(this).parents("div:first").html(...);
});
macOS Sierra 10.12.6. Wasn't able to install anything through pip (python installed through homebrew). All the answers above didn't work.
Eventually, upgrade from python 3.5 to 3.6 worked.
brew update
brew doctor #(in case you see such suggestion by brew)
then follow any additional suggestions by brew, i.e. overwrite link to python.
Make the div
of id="childdivimag"
a span
instead, and wrap that in an a
element. As the span
and img
are in-line elements by default this remains valid, whereas a div
is a block level element, and therefore invalid mark-up when contained within an a
.

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

For docker run
:
Simply add the option --user <user>
to change to another user when you start the docker container.
docker run -it --user nobody busybox
For docker attach
or docker exec
:
Since the command is used to attach/execute into the existing process, therefore it uses the current user there directly.
docker run -it busybox # CTRL-P/Q to quit
docker attach <container id> # then you have root user
/ # id
uid=0(root) gid=0(root) groups=10(wheel)
docker run -it --user nobody busybox # CTRL-P/Q to quit
docker attach <container id>
/ $ id
uid=99(nobody) gid=99(nogroup)
If you really want to attach to the user you want to have, then
run --user <user>
or mention it in your Dockerfile
using USER
The answer is yes, there is.
First you can easily install numpy use commands:
pip install numpy
Then you should install mkl, which is required by Scipy, and you can download it here
After download the file_name.whl you install it
C:\Users\****\Desktop\a> pip install mkl_service-1.1.2-cp35-cp35m-win32.whl
Processing c:\users\****\desktop\a\mkl_service-1.1.2-cp35-cp35m-win32.whl
Installing collected packages: mkl-service
Successfully installed mkl-service-1.1.2
Then at the same website you can download scipy-0.18.1-cp35-cp35m-win32.whl
Note:You should download the file_name.whl according to you python version, if you python version is 32bit python3.5 you should download this one, and the "win32" is about your python version, not your operating system version.
Then install file_name.whl like this:
C:\Users\****\Desktop\a>pip install scipy-0.18.1-cp35-cp35m-win32.whl
Processing c:\users\****\desktop\a\scipy-0.18.1-cp35-cp35m-win32.whl
Installing collected packages: scipy
Successfully installed scipy-0.18.1
Then there is only one more thing to do: comment out a specfic line or there will be error messages when you imput command "import scipy".
So comment out this line
from numpy._distributor_init import NUMPY_MKL # requires numpy+mkl
in this file: your_own_path\lib\site-packages\scipy__init__.py
Then you can use SciPy :)
Here tells you more about the last step.
Here is a similar anwser to a similar question.
I just wrote a version of this called "get_caller", I hope it helps. Mine is pretty lazy. You can just run get_caller() from a function, you don't have to specify it like this:
get_caller(__FUNCTION__);
Here's the script in full with a quirky test case:
<?php
/* This function will return the name string of the function that called $function. To return the
caller of your function, either call get_caller(), or get_caller(__FUNCTION__).
*/
function get_caller($function = NULL, $use_stack = NULL) {
if ( is_array($use_stack) ) {
// If a function stack has been provided, used that.
$stack = $use_stack;
} else {
// Otherwise create a fresh one.
$stack = debug_backtrace();
echo "\nPrintout of Function Stack: \n\n";
print_r($stack);
echo "\n";
}
if ($function == NULL) {
// We need $function to be a function name to retrieve its caller. If it is omitted, then
// we need to first find what function called get_caller(), and substitute that as the
// default $function. Remember that invoking get_caller() recursively will add another
// instance of it to the function stack, so tell get_caller() to use the current stack.
$function = get_caller(__FUNCTION__, $stack);
}
if ( is_string($function) && $function != "" ) {
// If we are given a function name as a string, go through the function stack and find
// it's caller.
for ($i = 0; $i < count($stack); $i++) {
$curr_function = $stack[$i];
// Make sure that a caller exists, a function being called within the main script
// won't have a caller.
if ( $curr_function["function"] == $function && ($i + 1) < count($stack) ) {
return $stack[$i + 1]["function"];
}
}
}
// At this stage, no caller has been found, bummer.
return "";
}
// TEST CASE
function woman() {
$caller = get_caller(); // No need for get_caller(__FUNCTION__) here
if ($caller != "") {
echo $caller , "() called " , __FUNCTION__ , "(). No surprises there.\n";
} else {
echo "no-one called ", __FUNCTION__, "()\n";
}
}
function man() {
// Call the woman.
woman();
}
// Don't keep him waiting
man();
// Try this to see what happens when there is no caller (function called from main script)
//woman();
?>
man() calls woman(), who calls get_caller(). get_caller() doesn't know who called it yet, because the woman() was cautious and didn't tell it, so it recurses to find out. Then it returns who called woman(). And the printout in source-code mode in a browser shows the function stack:
Printout of Function Stack:
Array
(
[0] => Array
(
[file] => /Users/Aram/Development/Web/php/examples/get_caller.php
[line] => 46
[function] => get_caller
[args] => Array
(

)
[1] => Array

(
[file] => /Users/Aram/Development/Web/php/examples/get_caller.php
[line] => 60
[function] => man

)
)
man() called woman(). No surprises there.
I was able to do that with the following 2 lines, I had an array called selected_items used to get all selected items on a dataTable
selected_items = null;
selected_items = [];
Without group by SUM(NVL(regular, 0) + NVL(overtime, 0))
will thrown an error and to avoid this we can simply use NVL(regular, 0) + NVL(overtime, 0)
Just to add an example with parameters:
class B(A):
def __init__(self, x, y, z):
A.__init__(self, x, y)
Given a derived class B that requires the variables x, y, z to be defined, and a superclass A that requires x, y to be defined, you can call the static method init of the superclass A with a reference to the current subclass instance (self) and then the list of expected arguments.
rabbitmqadmin is the perfect tool for this

This is not of much value in Java (1.5+) except when the type of object is Boolean
. In which case, this can still be handy.
if (object = null)
will not cause compilation failure in Java 1.5+ if object is Boolean
but would throw a NullPointerException
at runtime.
I was having a similar issue with a property being null or undefined.
This ended up being that IE's document mode was being defaulted to IE7 Standards. This was due to the compatibility mode being automatically set to be used for all intranet sites (Tools > Compatibility View Setting > Display Intranet Sites in Compatibility View).
For Spring 2.5, there's no @Primary
. The only way is to use @Qualifier
.
The width of the iphone is 320 . So put left and right value in Cell attribute for separatorInset more than half of 320 .
This three function are the same.
$(document).ready(function(){
})
and
$(function(){
});
and
jQuery(document).ready(function(){
});
here $
is used for define jQuery
like $
= jQuery
.
Now difference is that
$(document).ready
is jQuery event that is fired when DOM
is loaded, so it’s fired when the document structure is ready.
$(window).load
event is fired after whole content is loaded like page contain images,css etc.
I want to add another solution: In my case, I need to use a Enum group in a drop down button list items. So they might have space, i.e. more user friendly descriptions needed:
public enum CancelReasonsEnum
{
[Description("In rush")]
InRush,
[Description("Need more coffee")]
NeedMoreCoffee,
[Description("Call me back in 5 minutes!")]
In5Minutes
}
In a helper class (HelperMethods) I created the following method:
public static List<string> GetListOfDescription<T>() where T : struct
{
Type t = typeof(T);
return !t.IsEnum ? null : Enum.GetValues(t).Cast<Enum>().Select(x => x.GetDescription()).ToList();
}
When you call this helper you will get the list of item descriptions.
List<string> items = HelperMethods.GetListOfDescription<CancelReasonEnum>();
ADDITION: In any case, if you want to implement this method you need :GetDescription extension for enum. This is what I use.
public static string GetDescription(this Enum value)
{
Type type = value.GetType();
string name = Enum.GetName(type, value);
if (name != null)
{
FieldInfo field = type.GetField(name);
if (field != null)
{
DescriptionAttribute attr =Attribute.GetCustomAttribute(field,typeof(DescriptionAttribute)) as DescriptionAttribute;
if (attr != null)
{
return attr.Description;
}
}
}
return null;
/* how to use
MyEnum x = MyEnum.NeedMoreCoffee;
string description = x.GetDescription();
*/
}
These values vary from person to person, especially for people who are colorblind.
I resolve the problem. It's very simple . if do you checking care the problem may be because the auxiliar variable has whitespace. Why ? I don't know but yus must use the trim() method and will resolve the problem
You can make responsive grid of squares with verticaly and horizontaly centered content only with CSS. I will explain how in a step by step process but first here are 2 demos of what you can achieve :
Now let's see how to make these fancy responsive squares!
The trick for keeping elements square (or whatever other aspect ratio) is to use percent padding-bottom
.
Side note: you can use top padding too or top/bottom margin but the background of the element won't display.
As top padding is calculated according to the width of the parent element (See MDN for reference), the height of the element will change according to its width. You can now Keep its aspect ratio according to its width.
At this point you can code :
HTML :
<div></div>
CSS
div {
width: 30%;
padding-bottom: 30%; /* = width for a square aspect ratio */
}
Here is a simple layout example of 3*3 squares grid using the code above.
With this technique, you can make any other aspect ratio, here is a table giving the values of bottom padding according to the aspect ratio and a 30% width.
Aspect ratio | padding-bottom | for 30% width
------------------------------------------------
1:1 | = width | 30%
1:2 | width x 2 | 60%

As you can't add content directly inside the squares (it would expand their height and squares wouldn't be squares anymore) you need to create child elements (for this example I am using divs) inside them with position: absolute;
and put the content inside them. This will take the content out of the flow and keep the size of the square.
Don't forget to add position:relative;
on the parent divs so the absolute children are positioned/sized relatively to their parent.
Let's add some content to our 3x3 grid of squares :
HTML :
<div class="square">
<div class="content">
.. CONTENT HERE ..
</div>
</div>
... and so on 9 times for 9 squares ...
CSS :
.square {
float:left;
position: relative;
width: 30%;
padding-bottom: 30%; /* = width for a 1:1 aspect ratio */
margin:1.66%;
overflow:hidden;
}
.content {
position:absolute;
height:80%; /* = 100% - 2*10% padding */
width:90%; /* = 100% - 2*5% padding */
padding: 10% 5%;
}
RESULT <-- with some formatting to make it pretty!
Horizontally :
This is pretty easy, you just need to add text-align:center
to .content
.
RESULT
Vertical alignment
This becomes serious! The trick is to use
display:table;
/* and */
display:table-cell;
vertical-align:middle;
but we can't use display:table;
on .square
or .content
divs because it conflicts with position:absolute;
so we need to create two children inside .content
divs. Our code will be updated as follow :
HTML :
<div class="square">
<div class="content">
<div class="table">
<div class="table-cell">
... CONTENT HERE ...
</div>
</div>
</div>
</div>
... and so on 9 times for 9 squares ...
CSS :
.square {
float:left;
position: relative;
width: 30%;
padding-bottom : 30%; /* = width for a 1:1 aspect ratio */
margin:1.66%;
overflow:hidden;
}
.content {
position:absolute;
height:80%; /* = 100% - 2*10% padding */
width:90%; /* = 100% - 2*5% padding */
padding: 10% 5%;
}
.table{
display:table;
height:100%;
width:100%;
}
.table-cell{
display:table-cell;
vertical-align:middle;
height:100%;
width:100%;
}
We have now finished and we can take a look at the result here :
git push
is used to add commits you have done on the local repository to a remote one - together with git pull
, it allows people to collaborate.
Base on this I was able to solve this by changing the constructor of XmlSerializer
I was using instead of changing the classes.
Instead of using something like this (suggested in the other answers):
[XmlInclude(typeof(Derived))]
public class Base {}
public class Derived : Base {}
public void Serialize()
{
TextWriter writer = new StreamWriter(SchedulePath);
XmlSerializer xmlSerializer = new XmlSerializer(typeof(List<Derived>));
xmlSerializer.Serialize(writer, data);
writer.Close();
}
I did this:
public class Base {}
public class Derived : Base {}
public void Serialize()
{
TextWriter writer = new StreamWriter(SchedulePath);
XmlSerializer xmlSerializer = new XmlSerializer(typeof(List<Derived>), new[] { typeof(Derived) });
xmlSerializer.Serialize(writer, data);
writer.Close();
}
I could not get IE8+ to work by adding a jQuery event handler to the file input type. I had to go old-school and add the the onchange=""
attribute to the input tag:
<input type='file' onchange='getFilename(this)'/>
function getFileName(elm) {
var fn = $(elm).val();
....
}
EDIT:
function getFileName(elm) {
var fn = $(elm).val();
var filename = fn.match(/[^\\/]*$/)[0]; // remove C:\fakename
alert(filename);
}

The basic difference is that container
is scales responsively, while container-fluid
is always width:100%
. Therefore in the root CSS definitions, they appear the same, but if you look further you'll see that .container
is bound to media queries.
Bootstrap 4
The container
has 5 widths...
.container {
width: 100%;
}
@media (min-width: 576px) {
.container {
max-width: 540px;
}
}
@media (min-width: 768px) {
.container {
max-width: 720px;
}
}
@media (min-width: 992px) {
.container {
max-width: 960px;
}
}
@media (min-width: 1200px) {
.container {
max-width: 1140px;
}
}
Bootstrap 3
The container
has 4 sizes. Full width on xs
screens, and then it's width varies based on the following media queries..
@media (min-width: 1200px) {
.container {
width: 1170px;
}
}
@media (min-width: 992px) {
.container {
width: 970px;
}
}
@media (min-width: 768px) {
.container {
width: 750px;
}
}
You can try deleting package-lock.json
and running npm install
afterwards.
This worked for me.
Merging three dicts a,b,c in a single line without any other modules or libs
If we have the three dicts
a = {"a":9}
b = {"b":7}
c = {'b': 2, 'd': 90}
Merge all with a single line and return a dict object using
c = dict(a.items() + b.items() + c.items())
Returning
{'a': 9, 'b': 2, 'd': 90}

There is lots of stuff on this topic, each slightly different. Like many users I spent hours trying them and got nowhere. In the end, this is what worked for me - I.e. installed the driver on windows 8.1
In my extras/google/usb_driver is a file android_winusb.inf
I double clicked on this and it "ran" and installed the driver.
I can't explain why this worked.
To avoid the error, use extract string:
<string name="travels_tours_pvt_ltd"><![CDATA[Travels & Tours (Pvt) Ltd.]]></string>
Change the database.php file from
$db['default']['dbdriver'] = 'mysql';
to
$db['default']['dbdriver'] = 'mysqli';
No need to trim the array, simply address it as a circular buffer (index % maxlen). This will ensure it never goes over the limit (implementing a circular buffer means that once you get to the end you wrap around to the beginning again - not possible to overrun the end of the array).
For example:
var container = new Array ();
var maxlen = 100;
var index = 0;
// 'store' 1538 items (only the last 'maxlen' items are kept)
for (var i=0; i<1538; i++) {
container [index++ % maxlen] = "storing" + i;
}
// get element at index 11 (you want the 11th item in the array)
eleventh = container [(index + 11) % maxlen];
// get element at index 11 (you want the 11th item in the array)
thirtyfifth = container [(index + 35) % maxlen];
// print out all 100 elements that we have left in the array, note
// that it doesn't matter if we address past 100 - circular buffer
// so we'll simply get back to the beginning if we do that.
for (i=0; i<200; i++) {
document.write (container[(index + i) % maxlen] + "<br>\n");
}
Ahh... nevermind. It's always the search after the question is posed that yields the answer. My object that is being serialized is obj
and has already been defined. Adding an XMLSerializerNamespace with a single empty namespace to the collection does the trick.
In VB like this:
Dim xs As New XmlSerializer(GetType(cEmploymentDetail))
Dim ns As New XmlSerializerNamespaces()
ns.Add("", "")
Dim settings As New XmlWriterSettings()
settings.OmitXmlDeclaration = True
Using ms As New MemoryStream(), _
sw As XmlWriter = XmlWriter.Create(ms, settings), _
sr As New StreamReader(ms)
xs.Serialize(sw, obj, ns)
ms.Position = 0
Console.WriteLine(sr.ReadToEnd())
End Using
in C# like this:
//Create our own namespaces for the output
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
//Add an empty namespace and empty value
ns.Add("", "");
//Create the serializer
XmlSerializer slz = new XmlSerializer(someType);
//Serialize the object with our own namespaces (notice the overload)
slz.Serialize(myXmlTextWriter, someObject, ns);
Adding my solution for this issue for anyone it might help.
I had a ClickOnce solution throwing this error. The app referenced a common "Libs" folder and contained a project reference to a Foo.dll
. While none of the projects in the solution referenced the static copy of the Foo.dll
in the "Libs" folder, some of the references in that folder did (ie: my solution had refs to Libs\Bar.dll
which referenced Foo.dll
.) Since the CO app pulled all the dependencies from Libs
as well as their dependencies, both copies were going into the project. This was generating the error above.
I fixed the problem by moving my Libs\Foo.dll
static version into a subfolder, Libs\Fix\Foo.dll
. This change made the ClickOnce app use only the project version of the DLL and the error disappeared.
You can use that form:
return returnValue.Equals("1") ? true : false;
Or more simply (thanks to Jurijs Kastanovs):
return returnValue.Equals("1");
I was looking for a simple one-line solution to get the next month via math so I wouldn't have to look up the javascript date functions (mental laziness on my part). Quite strangely, I didn't find one here.
I overcame my brief bout of laziness, wrote one, and decided to share!
Solution:
(new Date().getMonth()+1)%12 + 1
Just to be clear why this works, let me break down the magic!
It gets the current month (which is in 0..11 format), increments by 1 for the next month, and wraps it to a boundary of 12 via modulus (11%12==11; 12%12==0). This returns the next month in the same 0..11 format, so converting to a format Date() will recognize (1..12) is easy: simply add 1 again.
Proof of concept:
> for(var m=0;m<=11;m++) { console.info( "next month for %i: %i", m+1, (m+1)%12 + 1 ) }
next month for 1: 2
next month for 2: 3
next month for 3: 4
next month for 4: 5
next month for 5: 6
next month for 6: 7
next month for 7: 8
next month for 8: 9
next month for 9: 10
next month for 10: 11
next month for 11: 12
next month for 12: 1
So there you have it.
The comprehensive place for Acrobat JavaScript documentation is the Acrobat SDK, which can be downloaded from the Adobe website. In the Documentation section, you will find all the material needed to work with Acrobat JavaScript.
To complete the documentation you may in addition get the specification of the JavaScript Core. My book of choice for that is "JavaScript, the Definitive Guide" by David Flanagan, published by O'Reilly.
Using the {# #}
notation, like so:
{# Everything you see here is a comment. It won't show up in the HTML output. #}
In MySQL you can do this:
INSERT IGNORE INTO Table2(Id, Name) SELECT Id, Name FROM Table1
Does SQL Server have anything similar?
Either:
DateTime dt = new DateTime();
or
DateTime dt = default(DateTime);
I know this is an old thread but I just wanted to add a little as the marked solution didn't solve the problem for me (although I tried many times).
The only way I could actually stop git form tracking the folder was to do the following:
git rm -r --cached your_folder/
your_folder/
to .gitignoreYou should now see that the folder is no longer tracked.
Don't ask me why just clearing the cache didn't work for me, I am not a Git super wizard but this is how I solved the issue.
You can use the IAsyncResult and Action class/interface to achieve this.
public void TimeoutExample()
{
IAsyncResult result;
Action action = () =>
{
// Your code here
};
result = action.BeginInvoke(null, null);
if (result.AsyncWaitHandle.WaitOne(10000))
Console.WriteLine("Method successful.");
else
Console.WriteLine("Method timed out.");
}
A coworker just pointed me to this nice little macro here
For ease I'll include the macro below.
#ifdef UNUSED
#elif defined(__GNUC__)
# define UNUSED(x) UNUSED_ ## x __attribute__((unused))
#elif defined(__LCLINT__)
# define UNUSED(x) /*@unused@*/ x
#else
# define UNUSED(x) x
#endif
void dcc_mon_siginfo_handler(int UNUSED(whatsig))
date.ToString("HH:mm:ss"); // for 24hr format
date.ToString("hh:mm:ss"); // for 12hr format, it shows AM/PM

Explicit access to module level variables by accessing them explicity on the module
In short: The technique described here is the same as in steveha's answer, except, that no artificial helper object is created to explicitly scope variables. Instead the module object itself is given a variable pointer, and therefore provides explicit scoping upon access from everywhere. (like assignments in local function scope).
Think of it like self for the current module instead of the current instance !
# db.py
import sys
# this is a pointer to the module object instance itself.
this = sys.modules[__name__]
# we can explicitly make assignments on it
this.db_name = None
def initialize_db(name):
if (this.db_name is None):
# also in local function scope. no scope specifier like global is needed
this.db_name = name
# also the name remains free for local use
db_name = "Locally scoped db_name variable. Doesn't do anything here."
else:
msg = "Database is already initialized to {0}."
raise RuntimeError(msg.format(this.db_name))
As modules are cached and therefore import only once, you can import db.py
as often on as many clients as you want, manipulating the same, universal state:
# client_a.py
import db
db.initialize_db('mongo')
# client_b.py
import db
if (db.db_name == 'mongo'):
db.db_name = None # this is the preferred way of usage, as it updates the value for all clients, because they access the same reference from the same module object
# client_c.py
from db import db_name
# be careful when importing like this, as a new reference "db_name" will
# be created in the module namespace of client_c, which points to the value
# that "db.db_name" has at import time of "client_c".
if (db_name == 'mongo'): # checking is fine if "db.db_name" doesn't change
db_name = None # be careful, because this only assigns the reference client_c.db_name to a new value, but leaves db.db_name pointing to its current value.
As an additional bonus I find it quite pythonic overall as it nicely fits Pythons policy of Explicit is better than implicit.
If you need to strip some end of a string if it exists otherwise do nothing. My best solutions. You probably will want to use one of first 2 implementations however I have included the 3rd for completeness.
For a constant suffix:
def remove_suffix(v, s):
return v[:-len(s)] if v.endswith(s) else v
remove_suffix("abc.com", ".com") == 'abc'
remove_suffix("abc", ".com") == 'abc'
For a regex:
def remove_suffix_compile(suffix_pattern):
r = re.compile(f"(.*?)({suffix_pattern})?$")
return lambda v: r.match(v)[1]
remove_domain = remove_suffix_compile(r"\.[a-zA-Z0-9]{3,}")
remove_domain("abc.com") == "abc"
remove_domain("sub.abc.net") == "sub.abc"
remove_domain("abc.") == "abc."
remove_domain("abc") == "abc"
For a collection of constant suffixes the asymptotically fastest way for a large number of calls:
def remove_suffix_preprocess(*suffixes):
suffixes = set(suffixes)
try:
suffixes.remove('')
except KeyError:
pass
def helper(suffixes, pos):
if len(suffixes) == 1:
suf = suffixes[0]
l = -len(suf)
ls = slice(0, l)
return lambda v: v[ls] if v.endswith(suf) else v
si = iter(suffixes)
ml = len(next(si))
exact = False
for suf in si:
l = len(suf)
if -l == pos:
exact = True
else:
ml = min(len(suf), ml)
ml = -ml
suffix_dict = {}
for suf in suffixes:
sub = suf[ml:pos]
if sub in suffix_dict:
suffix_dict[sub].append(suf)
else:
suffix_dict[sub] = [suf]
if exact:
del suffix_dict['']
for key in suffix_dict:
suffix_dict[key] = helper([s[:pos] for s in suffix_dict[key]], None)
return lambda v: suffix_dict.get(v[ml:pos], lambda v: v)(v[:pos])
else:
for key in suffix_dict:
suffix_dict[key] = helper(suffix_dict[key], ml)
return lambda v: suffix_dict.get(v[ml:pos], lambda v: v)(v)
return helper(tuple(suffixes), None)
domain_remove = remove_suffix_preprocess(".com", ".net", ".edu", ".uk", '.tv', '.co.uk', '.org.uk')
the final one is probably significantly faster in pypy then cpython. The regex variant is likely faster than this for virtually all cases that do not involve huge dictionaries of potential suffixes that cannot be easily represented as a regex at least in cPython.
In PyPy the regex variant is almost certainly slower for large number of calls or long strings even if the re module uses a DFA compiling regex engine as the vast majority of the overhead of the lambda's will be optimized out by the JIT.
In cPython however the fact that your running c code for the regex compare almost certainly outweighs the algorithmic advantages of the suffix collection version in almost all cases.

If you don't already have a C/C++ development environment installed that is compatible with the Visual Studio binaries distributed by Python.org, then you should stick to installing only pure Python packages or packages for which a Windows binary is available.
Fortunately, there are PyCrypto binaries available for Windows: http://www.voidspace.org.uk/python/modules.shtml#pycrypto
UPDATE:
As @Udi suggests in the comment below, the following command also installs pycrypto
and can be used in virtualenv
as well:
easy_install http://www.voidspace.org.uk/python/pycrypto-2.6.1/pycrypto-2.6.1.win32-py2.7.exe
Notice to choose the relevant link for your setup from this list
If you're looking for builds for Python 3.5, see PyCrypto on python 3.5
If you are looking for a more generalized way to apply to many columns, what you can do is to build a list of column names and pass it as the index of the grouped dataframe. In your case, for example:
columns = ['Y'+str(i) for year in range(1967, 2011)]
df.groupby('Country')[columns].agg('sum')
For anyone else who comes here looking, I'm afraid I'm with @usama sulaiman here.
Using the enqueue function provides a safe way to load style sheets and scripts according to the script dependencies and is WordPress' recommended method of achieving what the original poster was trying to achieve. Just think of all the plugins trying to load their own copy of jQuery for instance; you better hope they're using enqueue :D.
Also, wherever possible create a plugin; as adding custom code to your functions file can be pita if you don't have a back-up and you upgrade your theme and overwrite your functions file in the process.
Having a plugin handle this and other custom functions also means you can switch them off if you think their code is clashing with some other plugin or functionality.
Something along the following in a plugin file is what you are looking for:
<?php
/*
Plugin Name: Your plugin name
Description: Your description
Version: 1.0
Author: Your name
Author URI:
Plugin URI:
*/
function $yourJS() {
wp_enqueue_script(
'custom_script',
plugins_url( '/js/your-script.js', __FILE__ ),
array( 'jquery' )
);
}
add_action( 'wp_enqueue_scripts', '$yourJS' );
add_action( 'wp_enqueue_scripts', 'prefix_add_my_stylesheet' );
function prefix_add_my_stylesheet() {
wp_register_style( 'prefix-style', plugins_url( '/css/your-stylesheet.css', __FILE__ ) );
wp_enqueue_style( 'prefix-style' );
}
?>
Structure your folders as follows:
Plugin Folder
|_ css folder
|_ js folder
|_ plugin.php ...contains the above code - modified of course ;D
Then zip it up and upload it to your WordPress installation using your add plugins interface, activate it and Bob's your uncle.
if you changed the port to non standard one, then you need to specify it:
$connection = mysqli_connect('localhost:3308', 'root', '', 'loginapp');
ECMAScript 6 introduced the let
statement. You can use it in a for
statement.
var ids:string = [];
for(let result of this.results){
ids.push(result.Id);
}
It appears that a button that is used as the OK or CANCEL button for a ModalPopupExtender cannot have a click event. I tested this out by removing the
OkControlID="ModalOKButton"
from the ModalPopupExtender tag, and the button click fires. I'll need to figure out another way to send the data to the server.
Raising an event when a property changes is precisely what INotifyPropertyChanged does. There's one required member to implement INotifyPropertyChanged and that is the PropertyChanged event. Anything you implemented yourself would probably be identical to that implementation, so there's no advantage to not using it.
Louis's spliceSlice method fails when add value is 0 or other falsy values, here is a fix:
function spliceSlice(str, index, count, add) {
if (index < 0) {
index = str.length + index;
if (index < 0) {
index = 0;
}
}
const hasAdd = typeof add !== 'undefined';
return str.slice(0, index) + (hasAdd ? add : '') + str.slice(index + count);
}
I had a similar need, in which I wanted to use the output of last command into the next one. Much like a | (pipe). eg
$ which gradle
/usr/bin/gradle
$ ls -alrt /usr/bin/gradle
to something like -
$ which gradle |: ls -altr {}
Solution : Created this custom pipe. Really simple, using xargs -
$ alias :='xargs -I{}'
Basically nothing by creating a short hand for xargs, it works like charm, and is really handy. I just add the alias in .bash_profile file.
Here is a generic wrapper which can be used to convert a binary function to multi-parameters function. The benefit of this solution is that it is very generic and can be applied to any binary functions. You just need to do it once and then you can apply it any where.
To demo the idea, I use simple recursion to implement. It can be of course implemented with more elegant way that benefits from R's good support for functional paradigm.
fold_left <- function(f) {
return(function(...) {
args <- list(...)
return(function(...){
iter <- function(result,rest) {
if (length(rest) == 0) {
return(result)
} else {
return(iter(f(result, rest[[1]], ...), rest[-1]))
}
}
return(iter(args[[1]], args[-1]))
})
})}
Then you can simply wrap any binary functions with it and call with positional parameters (usually data.frames) in the first parentheses and named parameters in the second parentheses (such as by =
or suffix =
). If no named parameters, leave second parentheses empty.
merge_all <- fold_left(merge)
merge_all(df1, df2, df3, df4, df5)(by.x = c("var1", "var2"), by.y = c("var1", "var2"))
left_join_all <- fold_left(left_join)
left_join_all(df1, df2, df3, df4, df5)(c("var1", "var2"))
left_join_all(df1, df2, df3, df4, df5)()
Here's what worked for me:
git diff origin/master...
This shows only the changes between my currently selected local branch and the remote master branch, and ignores all changes in my local branch that came from merge commits.
If the python version is 3.X, it's okay.
I think your python version is 2.X, the super would work when adding this code
__metaclass__ = type
so the code is
__metaclass__ = type
class B:
def meth(self, arg):
print arg
class C(B):
def meth(self, arg):
super(C, self).meth(arg)
print C().meth(1)
I am a late comer, but maybe I can say this with a specific example:
Say, if you have a <table>
, with <tr>
, and then <td>
. Now, let's say you set 3 event handlers for the <td>
element, then if you do event.stopPropagation()
in the first event handler you set for <td>
, then all event handlers for <td>
will still run, but the event just won't propagate to <tr>
or <table>
(and won't go up and up to <body>
, <html>
, document
, and window
).
Now, however, if you use event.stopImmediatePropagation()
in your first event handler, then, the other two event handlers for <td>
WILL NOT run, and won't propagate up to <tr>
, <table>
(and won't go up and up to <body>
, <html>
, document
, and window
).
Note that it is not just for <td>
. For other elements, it will follow the same principle.
There are two ways to write case statements, you seem to be using a combination of the two
case a.updatedDate
when 1760 then 'Entered on' + a.updatedDate
when 1710 then 'Viewed on' + a.updatedDate
else 'Last Updated on' + a.updateDate
end
or
case
when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
else 'Last Updated on' + a.updateDate
end
are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.
Hash-Map stores the (key,value) pair as the Map.Entry Type.As you know that Hash-Map uses Linked Hash-Map(In case Collision occurs). Therefore each Node in the Bucket of Hash-Map is of Type Map.Entry. So whenever you iterate through the Hash-Map you will get Nodes of Type Map.Entry.
Now in your example when you are iterating through the Hash-Map, you will get Map.Entry Type(Which is Interface), To get the Key and Value from this Map.Entry Node Object, interface provided methods like getValue(), getKey() etc. So as per the code, In your Object you are adding all operators JButtons viz (+,-,/,*,=).
You can create script and then inject the content.
var g = document.createElement('script');
var s = document.getElementsByTagName('script')[0];
g.text = "alert(\"hi\");"
s.parentNode.insertBefore(g, s);
This works in all browsers :)
If Maven->Update Project doesn't work for you? These are the steps I religiously follow. Remove the project from eclipse (do not delete it from workspace) Close Eclipse go to command line and run these commands.
mvn eclipse:clean
mvn eclipse:eclipse -Dwtpversion=2.0
Open Eclipse import existing Maven project. You will see the maven dependency in our project.
Hope this works.
What i have done is that import a new project into eclipse workspace, and that path of that was be
android-sdk-macosx/extras/google/google_play_services/libproject/google-play-services_lib
and add as library in your project.. that it .. simple!! you might require to add support library in your project.
Just add click event by jquery in $(document).ready() like :
$(document).ready(function(){
$('#YourControlID').click(function(){
if(Check your condtion)
{
$.messager.show({
title:'My Title',
msg:'The message content',
showType:'fade',
style:{
right:'',
bottom:''
}
});
}
});
});
SQL Server 2012 and Later
Just use Try_Convert
instead:
TRY_CONVERT takes the value passed to it and tries to convert it to the specified data_type. If the cast succeeds, TRY_CONVERT returns the value as the specified data_type; if an error occurs, null is returned. However if you request a conversion that is explicitly not permitted, then TRY_CONVERT fails with an error.
SQL Server 2008 and Earlier
The traditional way of handling this is by guarding every expression with a case statement so that no matter when it is evaluated, it will not create an error, even if it logically seems that the CASE statement should not be needed. Something like this:
SELECT
Account_Code =
Convert(
bigint, -- only gives up to 18 digits, so use decimal(20, 0) if you must
CASE
WHEN X.Account_Code LIKE '%[^0-9]%' THEN NULL
ELSE X.Account_Code
END
),
A.Descr
FROM dbo.Account A
WHERE
Convert(
bigint,
CASE
WHEN X.Account_Code LIKE '%[^0-9]%' THEN NULL
ELSE X.Account_Code
END
) BETWEEN 503100 AND 503205
However, I like using strategies such as this with SQL Server 2005 and up:
SELECT
Account_Code = Convert(bigint, X.Account_Code),
A.Descr
FROM
dbo.Account A
OUTER APPLY (
SELECT A.Account_Code WHERE A.Account_Code NOT LIKE '%[^0-9]%'
) X
WHERE
Convert(bigint, X.Account_Code) BETWEEN 503100 AND 503205
What this does is strategically switch the Account_Code
values to NULL
inside of the X
table when they are not numeric. I initially used CROSS APPLY
but as Mikael Eriksson so aptly pointed out, this resulted in the same error because the query parser ran into the exact same problem of optimizing away my attempt to force the expression order (predicate pushdown defeated it). By switching to OUTER APPLY
it changed the actual meaning of the operation so that X.Account_Code
could contain NULL
values within the outer query, thus requiring proper evaluation order.
You may be interested to read Erland Sommarskog's Microsoft Connect request about this evaluation order issue. He in fact calls it a bug.
There are additional issues here but I can't address them now.
P.S. I had a brainstorm today. An alternate to the "traditional way" that I suggested is a SELECT
expression with an outer reference, which also works in SQL Server 2000. (I've noticed that since learning CROSS/OUTER APPLY
I've improved my query capability with older SQL Server versions, too--as I am getting more versatile with the "outer reference" capabilities of SELECT
, ON
, and WHERE
clauses!)
SELECT
Account_Code =
Convert(
bigint,
(SELECT A.AccountCode WHERE A.Account_Code NOT LIKE '%[^0-9]%')
),
A.Descr
FROM dbo.Account A
WHERE
Convert(
bigint,
(SELECT A.AccountCode WHERE A.Account_Code NOT LIKE '%[^0-9]%')
) BETWEEN 503100 AND 503205
It's a lot shorter than the CASE
statement.
It's impossible, and for a good reason (for one, think about all those catch(Exception){} around).
If you want to continue execution after stack overflow, run dangerous code in a different AppDomain. CLR policies can be set to terminate current AppDomain on overflow without affecting original domain.
You need to use lookahead as some of the other responders have said, but the lookahead has to account for other characters between its target word and the current match position. For example:
(?=.*word1)(?=.*word2)(?=.*word3)
The .*
in the first lookahead lets it match however many characters it needs to before it gets to "word1". Then the match position is reset and the second lookahead seeks out "word2". Reset again, and the final part matches "word3"; since it's the last word you're checking for, it isn't necessary that it be in a lookahead, but it doesn't hurt.
In order to match a whole paragraph, you need to anchor the regex at both ends and add a final .*
to consume the remaining characters. Using Perl-style notation, that would be:
/^(?=.*word1)(?=.*word2)(?=.*word3).*$/m
The 'm' modifier is for multline mode; it lets the ^
and $
match at paragraph boundaries ("line boundaries" in regex-speak). It's essential in this case that you not use the 's' modifier, which lets the dot metacharacter match newlines as well as all other characters.
Finally, you want to make sure you're matching whole words and not just fragments of longer words, so you need to add word boundaries:
/^(?=.*\bword1\b)(?=.*\bword2\b)(?=.*\bword3\b).*$/m
To get the number of rows in a dataframe use:
df.shape[0]
(and df.shape[1]
to get the number of columns).
As an alternative you can use
len(df)
or
len(df.index)
(and len(df.columns)
for the columns)
shape
is more versatile and more convenient than len()
, especially for interactive work (just needs to be added at the end), but len
is a bit faster (see also this answer).
To avoid: count()
because it returns the number of non-NA/null observations over requested axis
len(df.index)
is faster
import pandas as pd
import numpy as np
df = pd.DataFrame(np.arange(24).reshape(8, 3),columns=['A', 'B', 'C'])
df['A'][5]=np.nan
df
# Out:
# A B C
# 0 0 1 2
# 1 3 4 5
# 2 6 7 8
# 3 9 10 11
# 4 12 13 14
# 5 NaN 16 17
# 6 18 19 20
# 7 21 22 23
%timeit df.shape[0]
# 100000 loops, best of 3: 4.22 µs per loop
%timeit len(df)
# 100000 loops, best of 3: 2.26 µs per loop
%timeit len(df.index)
# 1000000 loops, best of 3: 1.46 µs per loop
df.__len__
is just a call to len(df.index)
import inspect
print(inspect.getsource(pd.DataFrame.__len__))
# Out:
# def __len__(self):
# """Returns length of info axis, but here we use the index """
# return len(self.index)
Why you should not use count()
df.count()
# Out:
# A 7
# B 8
# C 8

You won't be able to push changes to remote branch unless you unstage your staged files and then save local changes and apply the pull from remote and then you can push your changes to remote.
The steps are as follows-->
git reset --soft HEAD~1 ( to get the staged files)
git status (check the files which are staged)
git restore --staged <files..> (to restore the staged)
git stash (to save the current changes)
git pull (get changes from remote)
git stash apply (to apply the local changes in order to add and commit)
git add <files…> (add the local files for commit)
git commit -m ‘commit msg’
git push
std::string::compare() returns an int
:
s
and t
are equal,s
is less than t
,s
is greater than t
.If you want your first code snippet to be equivalent to the second one, it should actually read:
if (!s.compare(t)) {
// 's' and 't' are equal.
}
The equality operator only tests for equality (hence its name) and returns a bool
.
To elaborate on the use cases, compare()
can be useful if you're interested in how the two strings relate to one another (less or greater) when they happen to be different. PlasmaHH rightfully mentions trees, and it could also be, say, a string insertion algorithm that aims to keep the container sorted, a dichotomic search algorithm for the aforementioned container, and so on.
EDIT: As Steve Jessop points out in the comments, compare()
is most useful for quick sort and binary search algorithms. Natural sorts and dichotomic searches can be implemented with only std::less.
Here is an elegant solution.
There is hidden property for each input element on the form that you can use to determine whether or not the value was changed. Each type of input has it's own property name. For example
text/textarea
it's defaultValueselect
it's defaultSelectcheckbox/radio
it's defaultCheckedHere is the example.
function bindFormChange($form) {
function touchButtons() {
var
changed_objects = [],
$observable_buttons = $form.find('input[type="submit"], button[type="submit"], button[data-object="reset-form"]');
changed_objects = $('input:text, input:checkbox, input:radio, textarea, select', $form).map(function () {
var
$input = $(this),
changed = false;
if ($input.is('input:text') || $input.is('textarea') ) {
changed = (($input).prop('defaultValue') != $input.val());
}
if (!changed && $input.is('select') ) {
changed = !$('option:selected', $input).prop('defaultSelected');
}
if (!changed && $input.is('input:checkbox') || $input.is('input:radio') ) {
changed = (($input).prop('defaultChecked') != $input.is(':checked'));
}
if (changed) {
return $input.attr('id');
}
}).toArray();
if (changed_objects.length) {
$observable_buttons.removeAttr('disabled')
} else {
$observable_buttons.attr('disabled', 'disabled');
}
};
touchButtons();
$('input, textarea, select', $form).each(function () {
var $input = $(this);
$input.on('keyup change', function () {
touchButtons();
});
});
};
Now just loop thru the forms on the page and you should see submit buttons disabled by default and they will be activated ONLY if you indeed will change some input value on the form.
$('form').each(function () {
bindFormChange($(this));
});
Implementation as a jQuery
plugin is here https://github.com/kulbida/jmodifiable
i'd just do a simple check to see if d[a] exists and if not initialize it...
var a = "1",
b = "hello",
c = { "100" : "some important data" },
d = {};
if (d[a] === undefined) {
d[a] = {}
};
d[a]["greeting"] = b;
d[a]["data"] = c;
console.debug (d);
If you are using jQuery you can easily fetch the data attributes by
$(this).data("id") or $(event.target).data("id")
The problem is already in the language:
the idea to differentiate the output based on limited placeholder like '[name]' defines limitations.
I like the core functionality of webpack, but the usage requires a rewrite with abstract definitions which are based on logic and simplicity... the hardest thing in software-development... logic and simplicity.
All this could be solved by just providing a list of input/output definitions... A LIST INPUT/OUTPUT DEFINITIONS.
Although this comment doesn't help much but we can learn from our mistakes by pointing at them.
Vinod Kumar: Good workaround, its:
module.exports = {
plugins: [
new FileManagerPlugin({
events: {
onEnd: {
copy: [
{source: 'www', destination: './vinod test 1/'},
{source: 'www', destination: './vinod testing 2/'},
{source: 'www', destination: './vinod testing 3/'},
],
},
}
}),
],
};
BTW. this is my first comment on stackoverflow (after 10 years as a programmer) and stackoverflow sucks in usability, like why is there so much text everywhere ? my eyes are bleeding.
The second parameter must be a URI, not a domain name. i.e.
passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, "http://api.foursquare.com/", username, password)
This answer says to use
mapfile -t myArray < file.txt
I made a shim for mapfile
if you want to use mapfile
on bash < 4.x for whatever reason. It uses the existing mapfile
command if you are on bash >= 4.x
Currently, only options -d
and -t
work. But that should be enough for that command above. I've only tested on macOS. On macOS Sierra 10.12.6, the system bash is 3.2.57(1)-release
. So the shim can come in handy. You can also just update your bash with homebrew, build bash yourself, etc.
It uses this technique to set variables up one call stack.
Totally agree with @tir38 and @android_griezmann. This would be the version in kotlin:
interface servicesEndPoint {
@Multipart
@POST("user/updateprofile")
fun updateProfile(@Part("user_id") id:RequestBody, @Part("full_name") other:fullName, @Part image: MultipartBody.Part, @Part("other") other:RequestBody): Single<UploadPhotoResponse>
companion object {
val API_BASE_URL = "YOUR_URL"
fun create(): servicesPhotoEndPoint {
val retrofit = Retrofit.Builder()
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(API_BASE_URL)
.build()
return retrofit.create(servicesPhotoEndPoint::class.java)
}
}
}
// pass it like this
val file = File(RealPathUtils.getRealPathFromURI_API19(context, uri))
val requestFile: RequestBody = RequestBody.create(MediaType.parse("multipart/form-data"), file)
// MultipartBody.Part is used to send also the actual file name
val body: MultipartBody.Part = MultipartBody.Part.createFormData("image", file.name, requestFile)
// add another part within the multipart request
val fullName: RequestBody = RequestBody.create(MediaType.parse("multipart/form-data"), "Your Name")
servicesEndPoint.create().updateProfile(id, fullName, body, fullName)
To obtain the real path, use RealPathUtils. Check this class in the answers of @Harsh Bhavsar in this question: How to get the Full file path from URI.
To getRealPathFromURI_API19 you need permissions of READ_EXTERNAL_STORAGE
There are two obvious points, as well as the points in the other answer:
They are exactly equivalent when using sub queries:
SELECT * FROM table
WHERE column IN(subquery);
SELECT * FROM table
WHERE column = ANY(subquery);
On the other hand:
Only the IN
operator allows a simple list:
SELECT * FROM table
WHERE column IN(… , … , …);
Presuming they are exactly the same has caught me out several times when forgetting that ANY
doesn’t work with lists.
I made something like that:
$('#image-file').on('change', function() {
var numb = $(this)[0].files[0].size/1024/1024;
numb = numb.toFixed(2);
if(numb > 2){
alert('to big, maximum is 2MiB. You file size is: ' + numb +' MiB');
} else {
alert('it okey, your file has ' + numb + 'MiB')
}
});

Extract the contants into functions that describe them (basic refactoring):
FooBar fb = { foo(), bar() };
I know that style is very close to the one you didn't want to use, but it enables easier replacement of the constant values and also explain them (thus not needing to edit comments), if they ever change that is.
Another thing you could do (since you are lazy) is to make the constructor inline, so you don't have to type as much (removing "Foobar::" and time spent switching between h and cpp file):
struct FooBar {
FooBar(int f, float b) : foo(f), bar(b) {}
int foo;
float bar;
};
In order to use local gem repository in a Rails project, follow the steps below:
Check if your gem folder is a git repository (the command is executed in the gem folder)
git rev-parse --is-inside-work-tree
Getting repository path (the command is executed in the gem folder)
git rev-parse --show-toplevel
Setting up a local override for the rails application
bundle config local.GEM_NAME /path/to/local/git/repository
where GEM_NAME
is the name of your gem and /path/to/local/git/repository
is the output of the command in point 2
In your application Gemfile
add the following line:
gem 'GEM_NAME', :github => 'GEM_NAME/GEM_NAME', :branch => 'master'
Running bundle install
should give something like this:
Using GEM_NAME (0.0.1) from git://github.com/GEM_NAME/GEM_NAME.git (at /path/to/local/git/repository)
where GEM_NAME
is the name of your gem and /path/to/local/git/repository
from point 2
Finally, run bundle list
, not gem list
and you should see something like this:
GEM_NAME (0.0.1 5a68b88)
where GEM_NAME
is the name of your gem
A few important cases I am observing using:
Rails 4.0.2
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
Ubuntu 13.10
RubyMine 6.0.3
RubyMine
is not showing local gems as an external library. More information about the bug can be found here and herestop/start
the rails serverIf I am changing the version
of the gem, stopping/starting
the Rails server gives me an error. In order to fix it, I am specifying the gem version in the rails application Gemfile
like this:
gem 'GEM_NAME', '0.0.2', :github => 'GEM_NAME/GEM_NAME', :branch => 'master'
If you used
brew install python
before 'unlink' you got
brew info python
/usr/local/Cellar/python/2.7.11
python -V
Python 2.7.10
so do
brew unlink python && brew link python
and open a new terminal shell
python -V
Python 2.7.11
In later versions of PHP (>= 5.5.0) you can use this one-liner:
$key = array_search('100', array_column($userdb, 'uid'));
For me what works when I change the PATH is: exec "$BASH" --login
Java 10 did get local variable type inference, so now it has var
which is pretty much equivalent to the C# one (so far as I am aware).
It can also infer non-denotable types (types which couldn't be named in that place by the programmer; though which types are non-denotable is different). See e.g. Tricks with var
and anonymous classes (that you should never use at work).
The one difference I could find is that in C#,
In Java 10 var
is not a legal type name.
You need to create the variable to assign the new value to, like this:
String str = string.replaceAll("abcd","dddd");
You could do this:
if( ctrl[0].nodeName.toLowerCase() === 'input' ) {
// it was an input
}
or this, which is slower, but shorter and cleaner:
if( ctrl.is('input') ) {
// it was an input
}
If you want to be more specific, you can test the type:
if( ctrl.is('input:text') ) {
// it was an input
}
Another solution could be via pandas Series:
import pandas as pd
a = pd.Series([-2, 1, 5, 3, 8, 5, 6])
b = [1, 2, 5]
c = a[b]
You can then convert c back to a list if you want:
c = list(c)
Convert interface{}
into any type.
Syntax:
result := interface.(datatype)
Example:
var employee interface{} = []string{"Jhon", "Arya"}
result := employee.([]string) //result type is []string.
In my case the problem was caused by a browser extension that includes the bootstrap.js files where the show event handled twice and two modal-backdrop
divs are added, but when closing the modal only one of them is removed.
Found that by adding a subtree modification breakpoint to the body element in chrome, and tracked adding the modal-backdrop
divs.

Trying to make some order:
it all works - all but the firefox bookmarking function. for some reason the 'window.sidebar.addPanel' is not a function for the debugger, though it is working fine.
The problem is that it takes its values from the calling <a ..>
tag: title as the bookmark name and href as the bookmark address.
so this is my code:
javascript:
$("#bookmarkme").click(function () {
var url = 'http://' + location.host; // i'm in a sub-page and bookmarking the home page
var name = "Snir's Homepage";
if (navigator.userAgent.toLowerCase().indexOf('chrome') > -1){ //chrome
alert("In order to bookmark go to the homepage and press "
+ (navigator.userAgent.toLowerCase().indexOf('mac') != -1 ?
'Command/Cmd' : 'CTRL') + "+D.")
}
else if (window.sidebar) { // Mozilla Firefox Bookmark
//important for firefox to add bookmarks - remember to check out the checkbox on the popup
$(this).attr('rel', 'sidebar');
//set the appropriate attributes
$(this).attr('href', url);
$(this).attr('title', name);
//add bookmark:
// window.sidebar.addPanel(name, url, '');
// window.sidebar.addPanel(url, name, '');
window.sidebar.addPanel('', '', '');
}
else if (window.external) { // IE Favorite
window.external.addFavorite(url, name);
}
return;
});
html:
<a id="bookmarkme" href="#" title="bookmark this page">Bookmark This Page</a>
In internet explorer there is a different between 'addFavorite':
<a href="javascript:window.external.addFavorite('http://tiny.cc/snir','snir-site')">..</a>
and 'AddFavorite': <span onclick="window.external.AddFavorite(location.href, document.title);">..</span>
.
example here: http://www.yourhtmlsource.com/javascript/addtofavorites.html
Important, in chrome we can't add bookmarks using js (aspnet-i): http://www.codeproject.com/Questions/452899/How-to-add-bookmark-in-Google-Chrome-Opera-and-Saf
Yes, it means "not equal", either less than or greater than. e.g
If x <> y Then
can be read as
if x is less than y or x is greater than y then
The logical outcome being "If x is anything except equal to y"
Fundamentally you hadn't declare location which is what nginx uses to bind URL with resources.

location / {

index index.html index.htm index.php;
}
}
In Java, callback methods are mainly used to address the "Observer Pattern", which is closely related to "Asynchronous Programming".
Although callbacks are also used to simulate passing methods as a parameter, like what is done in functional programming languages.
I know that this question has been asked for a long time but as of today one simple answer is:
<img src="image.png" style="width: 55vw; min-width: 330px;" />
The use of vw in here tells that the width is relative to 55% of the width of the viewport.
All the major browsers nowadays support this.

I faced the same problem in eclipse with tomcat7 with the error javax.servlet cannot be resolved. If I select the server in targeted runtime mode and build project again, the error get's resolved.
I know that this is a bit of an old question, but I had this error recently so I thought I would pass my solution along.
My errors seem to stem from a old App.Config file and the "in place" upgrade from .Net 4.0 to .Net 4.5.1.
When I started the older project up after upgrading to Framework 4.5.1 I got the TypeInitializationException... right off the bat... not even able to step through one line of code.
After creating a brand new wpf project to test, I found that the newer App.Config file wants the following.
<configSections>
<sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="YourAppName.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
</sectionGroup>
</configSections>
Once I dropped that in, I was in business.
Note that your need might be slightly different. I would create a dummy project, check out the generated App.Config file and see if you have anything else missing.
Hope this helps someone. Happy Coding!
Mockito returns objects but static means "class level,not object level"So mockito will give null pointer exception for static.
Wait/block the Thread Main until some other threads complete their work.
As @Ravindra babu
said it can be achieved in various ways, but showing with examples.
java.lang.Thread.join() Since:1.0
public static void joiningThreads() throws InterruptedException {
Thread t1 = new Thread( new LatchTask(1, null), "T1" );
Thread t2 = new Thread( new LatchTask(7, null), "T2" );
Thread t3 = new Thread( new LatchTask(5, null), "T3" );
Thread t4 = new Thread( new LatchTask(2, null), "T4" );
// Start all the threads
t1.start();
t2.start();
t3.start();
t4.start();
// Wait till all threads completes
t1.join();
t2.join();
t3.join();
t4.join();
}
java.util.concurrent.CountDownLatch Since:1.5
.countDown()
« Decrements the count of the latch group..await()
« The await methods block until the current count reaches zero.If you created latchGroupCount = 4
then countDown()
should be called 4 times to make count 0. So, that await()
will release the blocking threads.
public static void latchThreads() throws InterruptedException {
int latchGroupCount = 4;
CountDownLatch latch = new CountDownLatch(latchGroupCount);
Thread t1 = new Thread( new LatchTask(1, latch), "T1" );
Thread t2 = new Thread( new LatchTask(7, latch), "T2" );
Thread t3 = new Thread( new LatchTask(5, latch), "T3" );
Thread t4 = new Thread( new LatchTask(2, latch), "T4" );
t1.start();
t2.start();
t3.start();
t4.start();
//latch.countDown();
latch.await(); // block until latchGroupCount is 0.
}
Example code of Threaded class LatchTask
. To test the approach use joiningThreads();
and latchThreads();
from main method.
class LatchTask extends Thread {
CountDownLatch latch;
int iterations = 10;
public LatchTask(int iterations, CountDownLatch latch) {
this.iterations = iterations;
this.latch = latch;
}
@Override
public void run() {
String threadName = Thread.currentThread().getName();
System.out.println(threadName + " : Started Task...");
for (int i = 0; i < iterations; i++) {
System.out.println(threadName + " : " + i);
MainThread_Wait_TillWorkerThreadsComplete.sleep(1);
}
System.out.println(threadName + " : Completed Task");
// countDown() « Decrements the count of the latch group.
if(latch != null)
latch.countDown();
}
}
CyclicBarrier barrier = new CyclicBarrier(3);
barrier.await();
For example refer this Concurrent_ParallelNotifyies class.Executer framework: we can use ExecutorService to create a thread pool, and tracks the progress of the asynchronous tasks with Future.
submit(Runnable)
, submit(Callable)
which return Future Object. By using future.get()
function we can block the main thread till the working threads completes its work.
invokeAll(...)
- returns a list of Future objects via which you can obtain the results of the executions of each Callable.
Find example of using Interfaces Runnable, Callable with Executor framework.

To get lifetime Access Token you have to use scope=offline_access
Meaning of scope=offline_access
is that :-
Enables your application to perform authorized requests on behalf of the user at any time. By default, most access tokens expire after a short time period to ensure applications only make requests on behalf of the user when the are actively using the application. This permission makes the access token returned by our OAuth endpoint long-lived.
But according to facebook future upgradation the offline_acees functionality will be deprecated for forever from the 3rd October, 2012. and the user will be given 60 days long-lived access token and before expiration of the access token Facebook will notify or you can get your custom notification functionality fetching the expiration value from the Facebook Api..
Don't abuse form elements where <a> elements will suffice.

An easy workaround might be to simply mount the volume (using the -v or --mount flag) to the container when you run it and access the files that way.
example:
docker run -v /path/to/file/on/host:/desired/path/to/file/in/container/ image_name
for more see: https://docs.docker.com/storage/volumes/
I like to do it like old times. You just use a custom UITextField Class like this one:
//
// ReadOnlyTextField.swift
// MediFormulas

//
import UIKit
class ReadOnlyTextField: UITextField {
/*
// Only override draw() if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func draw(_ rect: CGRect) {
// Drawing code
}
*/
override init(frame: CGRect) {
super.init(frame: frame)
// Avoid keyboard to show up
self.inputView = UIView()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
// Avoid keyboard to show up
self.inputView = UIView()
}
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
// Avoid cut and paste option show up
if (action == #selector(self.cut(_:))) {
return false
} else if (action == #selector(self.paste(_:))) {
return false
}
return super.canPerformAction(action, withSender: sender)
}
}
I came across this answer trying to style the ReCaptcha v2 for a site that has a light and a dark mode. Played around some more and discovered that besides transform
, filter
is also applied to iframe
elements so ended up using the default/light ReCaptcha and doing this when the user is in dark mode:
.g-recaptcha {
filter: invert(1) hue-rotate(180deg);
}
The hue-rotate(180deg)
makes it so that the logo is still blue and the check-mark is still green when the user clicks it, while keeping white invert()
'ed to black and vice versa.
Didn't see this in any answer or comment so decided to share even if this is an old thread.
We're all working around some old bugs that haven't been fixed likely because it's "by design." I ran into the freezing problem @iwasrobbed described elsewhere when trying to nil the interactivePopGestureRecognizer
's delegate which seemed like it should've worked. If you want swipe behavior reconsider using backBarButtonItem
which you can customize.
I also ran into interactivePopGestureRecognizer
not working when the UINavigationBar
is hidden. If hiding the navigation bar is a concern for you, reconsider your design before implementing a workaround for a bug.
To close all splits, I usually place the cursor in the window that shall be the on-ly visible one and then do :on
which makes the current window the on-ly visible window. Nice mnemonic to remember.
Edit: :help :on
showed me that these commands are the same:
Each of these four closes all windows except the active one.

Parallel.ForEach will optimize(may not even start new threads) and block until the loop is finished, and Task.Factory will explicitly create a new task instance for each item, and return before they are finished (asynchronous tasks). Parallel.Foreach is much more efficient.

Paul Irish's approach to IE specific CSS is the most elegant I've seen. It uses conditional statements to add classes to the HTML element, which can then be used to apply appropriate IE version specific CSS without resorting to hacks. The CSS validates, and it will continue to work down the line for future browser versions.
The full details of the approach can be seen on his site.
This doesn't cover browser specific hacks for Mozilla and Chrome... but I don't really find I need those anyway.
There is a work-around that works in jQuery 1.3.2 and 1.4.2:
$("#myCheckbox").change( function() {
alert($(this).is(":checked"));
});
//Trigger by:
$("#myCheckbox").trigger('click').trigger('change');?????????????
But I agree, this behavior seems buggy compared to the native event.
map
is implemented from balanced binary search tree
(usually a rb_tree
), since all the member in balanced binary search tree
is sorted so is map;
hash_map
is implemented from hashtable
.Since all the member in hashtable
is unsorted so the members in hash_map(unordered_map)
is not sorted.
hash_map
is not a c++ standard library, but now it renamed to unordered_map
(you can think of it renamed) and becomes c++ standard library since c++11 see this question Difference between hash_map and unordered_map? for more detail.
Below i will give some core interface from source code of how the two type map is implemented.
The below code is just to show that, map is just a wrapper of an balanced binary search tree
, almost all it's function is just invoke the balanced binary search tree
function.
template <typename Key, typename Value, class Compare = std::less<Key>>
class map{
// used for rb_tree to sort
typedef Key key_type;
// rb_tree node value
typedef std::pair<key_type, value_type> value_type;
typedef Compare key_compare;
// as to map, Key is used for sort, Value used for store value
typedef rb_tree<key_type, value_type, key_compare> rep_type;
// the only member value of map (it's rb_tree)
rep_type t;
};
// one construct function
template<typename InputIterator>
map(InputIterator first, InputIterator last):t(Compare()){
// use rb_tree to insert value(just insert unique value)
t.insert_unique(first, last);
}
// insert function, just use tb_tree insert_unique function
//and only insert unique value
//rb_tree insertion time is : log(n)+rebalance
// so map's insertion time is also : log(n)+rebalance
typedef typename rep_type::const_iterator iterator;
std::pair<iterator, bool> insert(const value_type& v){
return t.insert_unique(v);
};
hash_map
:hash_map
is implemented from hashtable
whose structure is somewhat like this:
In the below code, i will give the main part of hashtable
, and then gives hash_map
.
// used for node list
template<typename T>
struct __hashtable_node{
T val;
__hashtable_node* next;
};
template<typename Key, typename Value, typename HashFun>
class hashtable{
public:
typedef size_t size_type;
typedef HashFun hasher;
typedef Value value_type;
typedef Key key_type;
public:
typedef __hashtable_node<value_type> node;
// member data is buckets array(node* array)
std::vector<node*> buckets;
size_type num_elements;
public:
// insert only unique value
std::pair<iterator, bool> insert_unique(const value_type& obj);
};
Like map's
only member is rb_tree
, the hash_map's
only member is hashtable
. It's main code as below:
template<typename Key, typename Value, class HashFun = std::hash<Key>>
class hash_map{
private:
typedef hashtable<Key, Value, HashFun> ht;
// member data is hash_table
ht rep;
public:
// 100 buckets by default
// it may not be 100(in this just for simplify)
hash_map():rep(100){};
// like the above map's insert function just invoke rb_tree unique function
// hash_map, insert function just invoke hashtable's unique insert function
std::pair<iterator, bool> insert(const Value& v){
return t.insert_unique(v);
};
};
Below image shows when a hash_map have 53 buckets, and insert some values, it's internal structure.
The below image shows some difference between map and hash_map(unordered_map), the image comes from How to choose between map and unordered_map?:
Since dob
is DATE
data type, you need to convert the literal to DATE
using TO_DATE
and the proper format model. The syntax is:
TO_DATE('<date_literal>', '<format_model>')
For example,
SQL> CREATE TABLE t(dob DATE);
Table created.
SQL> INSERT INTO t(dob) VALUES(TO_DATE('17/12/2015', 'DD/MM/YYYY'));
1 row created.
SQL> COMMIT;
Commit complete.
SQL> SELECT * FROM t;
DOB
----------
17/12/2015
A DATE
data type contains both date and time elements. If you are not concerned about the time portion, then you could also use the ANSI Date literal which uses a fixed format 'YYYY-MM-DD'
and is NLS independent.
For example,
SQL> INSERT INTO t(dob) VALUES(DATE '2015-12-17');
1 row created.
I believe that although javascript is an option here, you have a smoother animation through forcing hardware accelerate with CSS3. You can achieve this by setting the following CSS3 properties on the moving div:
div.hardware-accelarate {
-webkit-transform: translate3d(0,0,0);
-moz-transform: translate3d(0,0,0);
-ms-transform: translate3d(0,0,0);
-o-transform: translate3d(0,0,0);
transform: translate3d(0,0,0);
}
I've made a plunkr setup for ya'll to test and tweak...
You need to specify the column in both expressions.
SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'
def sort_np_array(x, column=None, flip=False):
x = x[np.argsort(x[:, column])]
if flip:
x = np.flip(x, axis=0)
return x
Array in the original question:
a = np.array([[9, 2, 3],
[4, 5, 6],
[7, 0, 5]])
The result of the sort_np_array
function as expected by the author of the question:
sort_np_array(a, column=1, flip=False)
[2]: array([[7, 0, 5],
[9, 2, 3],
[4, 5, 6]])
UPDATE t1
LEFT JOIN
t2
ON t2.id = t1.id
SET t1.col1 = newvalue
WHERE t2.id IS NULL
Note that for a SELECT
it would be more efficient to use NOT IN
/ NOT EXISTS
syntax:
SELECT t1.*
FROM t1
WHERE t1.id NOT IN
(
SELECT id
FROM t2
)
See the article in my blog for performance details:
LEFT JOIN
compared to NOT IN
Unfortunately, MySQL
does not allow using the target table in a subquery in an UPDATE
statement, that's why you'll need to stick to less efficient LEFT JOIN
syntax.
On the Unity Editor open your project and:
If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:
cd to/your/unity/project/folder
git init
git add *
git commit -m "First commit"
git remote add origin [email protected]:username/project.git
git push -u origin master
You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).
Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.
And here's my own .gitignore recipe for my Unity projects:

To keep the whitespace between words, you also need to include the tilde ~
.
It is a Child Selector.
It matches when an element is the child of some element. It is made up of two or more selectors separated by ">".
Example(s):
The following rule sets the style of all P elements that are children of BODY:
body > P { line-height: 1.3 }
Example(s):
The following example combines descendant selectors and child selectors:
div ol>li p
It matches a P element that is a descendant of an LI; the LI element must be the child of an OL element; the OL element must be a descendant of a DIV. Notice that the optional white space around the ">" combinator has been left out.
