ModelState.AddModelError - How can I add an error that isn't for a property?
Putting the model dot property in strings worked for me: ModelState.AddModelError("Item1.Month", "This is not a valid date");
How to download a file with Node.js (without using third-party libraries)?
Without library it could be buggy just to point out. Here are a few:
- Can't handle http redirection, like this url https://calibre-ebook.com/dist/portable which is binary.
- http module can't https url, you will get
Protocol "https:" not supported.
Here my suggestion:
- Call system tool like
wgetorcurl - use some tool like node-wget-promise which also very simple to use.
var wget = require('node-wget-promise'); wget('http://nodejs.org/images/logo.svg');
JavaScript hashmap equivalent
Adding yet another solution: HashMap is pretty much the first class I ported from Java to JavaScript. You could say there is a lot of overhead, but the implementation is almost 100% equal to Java's implementation and includes all interfaces and subclasses.
The project can be found here: https://github.com/Airblader/jsava I'll also attach the (current) source code for the HashMap class, but as stated it also depends on the super class, etc. The OOP framework used is qooxdoo.
Please note that this code is already out-dated and refer to the GitHub project for the current work. As of writing this, there is also an ArrayList implementation.

Package doesn't exist error in intelliJ
If you are trying the suggested ways and still no chance, be sure about your order:
- Delete your .idea/
- Invalidate and Restart Cache afterwards
- Import maven projects from your maven tool
If you did not invalidate and restart cache just after deleting your .idea/, Intellij keeps generating it and that was keeping error in my case.
Debugging Spring configuration
If you use Spring Boot, you can also enable a “debug” mode by starting your application with a --debug flag.
java -jar myapp.jar --debug
You can also specify debug=true in your application.properties.
When the debug mode is enabled, a selection of core loggers (embedded container, Hibernate, and Spring Boot) are configured to output more information. Enabling the debug mode does not configure your application to log all messages with DEBUG level.
Alternatively, you can enable a “trace” mode by starting your application with a --trace flag (or trace=true in your application.properties). Doing so enables trace logging for a selection of core loggers (embedded container, Hibernate schema generation, and the whole Spring portfolio).

Add onclick event to newly added element in JavaScript
Short answer: you want to set the handler to a function:
elemm.onclick = function() { alert('blah'); };
Slightly longer answer: you'll have to write a few more lines of code to get that to work consistently across browsers.
The fact is that even the sligthly-longer-code that might solve that particular problem across a set of common browsers will still come with problems of its own. So if you don't care about cross-browser support, go with the totally short one. If you care about it and absolutely only want to get this one single thing working, go with a combination of addEventListener and attachEvent. If you want to be able to extensively create objects and add and remove event listeners throughout your code, and want that to work across browsers, you definitely want to delegate that responsibility to a library such as jQuery.
Git Push ERROR: Repository not found
I'm using Mac and I struggled to find the solution. My remote address was right and as said, it was a credentials problem. Apparently, in the past I used another Git Account on my computer and the mac's Keychain remembered the credentials of the previous account, so I really wasn't authorised to push.
How to fix? Open Keychain Access on your mac, choose "All Items" category and search for git. Delete all results found.
Now go to the terminal and try to push again. The terminal will ask for username and password. Enter the new relevant credentials and that's it!
Hope it'll help someone. I struggled it for few hours.

WRONGTYPE Operation against a key holding the wrong kind of value php
This error means that the value indexed by the key "l_messages" is not of type hash, but rather something else. You've probably set it to that other value earlier in your code. Try various other value-getter commands, starting with GET, to see which one works and you'll know what type is actually here.
Export HTML table to pdf using jspdf
Use get(0) instead of html(). In other words, replace
doc.fromHTML($('#htmlTableId').html(), 15, 15, {
'width': 170,'elementHandlers': specialElementHandlers
});
with
doc.fromHTML($('#htmlTableId').get(0), 15, 15, {
'width': 170,'elementHandlers': specialElementHandlers
});
Converting to upper and lower case in Java
I consider this simpler than any prior correct answer. I'll also throw in javadoc. :-)
/**
* Converts the given string to title case, where the first
* letter is capitalized and the rest of the string is in
* lower case.
*
* @param s a string with unknown capitalization
* @return a title-case version of the string
*/
public static String toTitleCase(String s)
{
if (s.isEmpty())
{
return s;
}
return s.substring(0, 1).toUpperCase() + s.substring(1).toLowerCase();
}
Strings of length 1 do not needed to be treated as a special case because s.substring(1) returns the empty string when s has length 1.
Angular.js directive dynamic templateURL
Thanks to @pgregory, I could resolve my problem using this directive for inline editing
.directive("superEdit", function($compile){
return{
link: function(scope, element, attrs){
var colName = attrs["superEdit"];
alert(colName);
scope.getContentUrl = function() {
if (colName == 'Something') {
return 'app/correction/templates/lov-edit.html';
}else {
return 'app/correction/templates/simple-edit.html';
}
}
var template = '<div ng-include="getContentUrl()"></div>';
var linkFn = $compile(template);
var content = linkFn(scope);
element.append(content);
}
}
})
Why is String immutable in Java?
I read this post Why String is Immutable or Final in Java and suppose that following may be the most important reason:
String is Immutable in Java because String objects are cached in String pool. Since cached String literals are shared between multiple clients there is always a risk, where one client's action would affect all another client.

Laravel Eloquent update just if changes have been made
I like to add this method, if you are using an edit form, you can use this code to save the changes in your update(Request $request, $id) function:
$post = Post::find($id);
$post->fill($request->input())->save();
keep in mind that you have to name your inputs with the same column name. The fill() function will do all the work for you :)
docker-compose up for only certain containers
You can use the run command and specify your services to run. Be careful, the run command does not expose ports to the host. You should use the flag --service-ports to do that if needed.

window.clipboardData.getData('Text') will work in some browsers. However, many browsers where it does work will prompt the user as to whether or not they wish the web page to have access to the clipboard.
How do I print a list of "Build Settings" in Xcode project?
UPDATE: This list is getting a little out dated (it was generated with Xcode 4.1). You should run the command suggested by dunedin15.
dunedin15's answer can give inaccurate results for some edge-cases, such as when debugging build settings of a static lib for an Archive build, see Slipp D. Thompson's answer for a more robust output.

Find non-ASCII characters in varchar columns using SQL Server
Here is a UDF I built to detectc columns with extended ascii charaters. It is quick and you can extended the character set you want to check. The second parameter allows you to switch between checking anything outside the standard character set or allowing an extended set:
create function [dbo].[udf_ContainsNonASCIIChars]
(
@string nvarchar(4000),
@checkExtendedCharset bit
)
returns bit
as
begin
declare @pos int = 0;
declare @char varchar(1);
declare @return bit = 0;
while @pos < len(@string)
begin
select @char = substring(@string, @pos, 1)
if ascii(@char) < 32 or ascii(@char) > 126
begin
if @checkExtendedCharset = 1
begin
if ascii(@char) not in (9,124,130,138,142,146,150,154,158,160,170,176,180,181,183,184,185,186,192,193,194,195,196,197,199,200,201,202,203,204,205,206,207,209,210,211,212,213,214,216,217,218,219,220,221,223,224,225,226,227,228,229,230,231,232,233,234,235,236,237,238,239,240,241,242,243,244,245,246,248,249,250,251,252,253,254,255)
begin
select @return = 1;
select @pos = (len(@string) + 1)
end
else
begin
select @pos = @pos + 1
end
end
else
begin
select @return = 1;
select @pos = (len(@string) + 1)
end
end
else
begin
select @pos = @pos + 1
end
end
return @return;
end
USAGE:
select Address1
from PropertyFile_English
where udf_ContainsNonASCIIChars(Address1, 1) = 1
Get variable from PHP to JavaScript
You can pass PHP Variables to your JavaScript by generating it with PHP:
<?php
$someVar = 1;
?>
<script type="text/javascript">
var javaScriptVar = "<?php echo $someVar; ?>";
</script>
Getting input values from text box
You will notice you have no value attr in the input tags.
Also, although not shown, make sure the Javascript is run after the html is in place.

how to output every line in a file python
Did you try
for line in open("masters", "r").readlines(): print line
?
readline()
only reads "a line", on the other hand
readlines()
reads whole lines and gives you a list of all lines.
How to Programmatically Add Views to Views
This is late but this may help someone :) :) For adding the view programmatically try like
LinearLayout rlmain = new LinearLayout(this);
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.FILL_PARENT);
LinearLayout ll1 = new LinearLayout (this);
ImageView iv = new ImageView(this);
iv.setImageResource(R.drawable.logo);
LinearLayout .LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
iv.setLayoutParams(lp);
ll1.addView(iv);
rlmain.addView(ll1);
setContentView(rlmain, llp);
This will create your entire view programmatcally. You can add any number of view as same. Hope this may help. :)
std::thread calling method of class
Not so hard:
#include <thread>
void Test::runMultiThread()
{
std::thread t1(&Test::calculate, this, 0, 10);
std::thread t2(&Test::calculate, this, 11, 20);
t1.join();
t2.join();
}
If the result of the computation is still needed, use a future instead:
#include <future>
void Test::runMultiThread()

Writing MemoryStream to Response Object
Assuming you can get a Stream, FileStream or MemoryStream for instance, you can do this:
Stream file = [Some Code that Gets you a stream];
var filename = [The name of the file you want to user to download/see];
if (file != null && file.CanRead)
{
context.Response.AddHeader("Content-Disposition", "attachment; filename=\"" + filename + "\"");
context.Response.ContentType = "application/octet-stream";
context.Response.ClearContent();
file.CopyTo(context.Response.OutputStream);
}
Thats a copy and paste from some of my working code, so the content type might not be what youre looking for, but writing the stream to the response is the trick on the last line.

How to select a value in dropdown javascript?
Use the selectedIndex property:
document.getElementById("Mobility").selectedIndex = 12; //Option 10
Alternate method:
Loop through each value:
//Get select object
var objSelect = document.getElementById("Mobility");
//Set selected
setSelectedValue(objSelect, "10");
function setSelectedValue(selectObj, valueToSet) {
for (var i = 0; i < selectObj.options.length; i++) {
if (selectObj.options[i].text== valueToSet) {
selectObj.options[i].selected = true;
return;
}
}
}
Eclipse: Syntax Error, parameterized types are only if source level is 1.5

.... tada...done... :)
How do I add images in laravel view?
If Image folder location is public/assets/img/default.jpg.
You can try in view
<img src="{{ URL::to('/assets/img/default.jpg') }}">
Does calling clone() on an array also clone its contents?
The clone is a shallow copy of the array.
This test code prints:
[1, 2] / [1, 2] [100, 200] / [100, 2]
because the MutableInteger is shared in both arrays as objects[0] and objects2[0], but you can change the reference objects[1] independently from objects2[1].
import java.util.Arrays;
public class CloneTest {
static class MutableInteger {
int value;
MutableInteger(int value) {
this.value = value;
}
@Override
public String toString() {
return Integer.toString(value);
}
}
public static void main(String[] args) {
MutableInteger[] objects = new MutableInteger[] {
new MutableInteger(1), new MutableInteger(2) };
MutableInteger[] objects2 = objects.clone();
System.out.println(Arrays.toString(objects) + " / " +
Arrays.toString(objects2));
objects[0].value = 100;
objects[1] = new MutableInteger(200);
System.out.println(Arrays.toString(objects) + " / " +
Arrays.toString(objects2));
}
}
How to stretch in width a WPF user control to its window?

How to catch and print the full exception traceback without halting/exiting the program?
This is my solution to write the error in a log file and also on console:
import logging, sys
import traceback
logging.basicConfig(filename='error.log', level=logging.DEBUG)
def handle_exception(exc_type, exc_value, exc_traceback):
import sys
if issubclass(exc_type, KeyboardInterrupt):
sys.__excepthook__(exc_type, exc_value, exc_traceback)
return
exc_info=(exc_type, exc_value, exc_traceback)
logging.critical("\nDate:" + str(datetime.datetime.now()), exc_info=(exc_type, exc_value, exc_traceback))
print("An error occured, check error.log to see the error details")
traceback.print_exception(*exc_info)
sys.excepthook = handle_exception
Convert AM/PM time to 24 hours format?
Go through following code to convert the DateTime from 12 hrs to 24 hours.
string currentDateString = DateTime.Now.ToString("dd-MMM-yyyy h:mm tt");
DateTime currentDate = Convert.ToDateTime(currentDateString);
Console.WriteLine("String Current Date: " + currentDateString);
Console.WriteLine("Converted Date: " + currentDate.ToString("dd-MMM-yyyy HH:mm"));
Whenever you want the time should be displayed in24 hours use format "HH"
You can refer following link for further details: Custom Date and Time Format Strings
pip install fails with "connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:598)"
You can specify a cert with this param:
pip --cert /etc/ssl/certs/FOO_Root_CA.pem install linkchecker
See: Docs » Reference Guide » pip
If specifying your company's root cert doesn't work maybe the cURL one will work: http://curl.haxx.se/ca/cacert.pem
You must use a PEM file and not a CRT file. If you have a CRT file you will need to convert the file to PEM There are reports in the comments that this now works with a CRT file but I have not verified.
Also check: SSL Cert Verification.
Token Authentication vs. Cookies
I believe that there is some confusion here. The significant difference between cookie based authentication and what is now possible with HTML5 Web Storage is that browsers are built to send cookie data whenever they are requesting resources from the domain that set them. You can't prevent that without turning off cookies. Browsers do not send data from Web Storage unless code in the page sends it. And pages can only access data that they stored, not data stored by other pages.
So, a user worried about the way that their cookie data might be used by Google or Facebook might turn off cookies. But, they have less reason to turn off Web Storage (until the advertisers figure a way to use that as well).
So, that's the difference between cookie based and token based, the latter uses Web Storage.
Unit Testing: DateTime.Now
Here is my anwer of this question. I combine the 'Ambient Context' pattern with IDisposable. So you can use the DateTimeProvider.Current in your normal program code and in the test you override the scope with a using statement.
using System;
using System.Collections.Immutable;
namespace ambientcontext {
public abstract class DateTimeProvider : IDisposable
{
private static ImmutableStack<DateTimeProvider> stack = ImmutableStack<DateTimeProvider>.Empty.Push(new DefaultDateTimeProvider());
protected DateTimeProvider()
{
if (this.GetType() != typeof(DefaultDateTimeProvider))
stack = stack.Push(this);
}
public static DateTimeProvider Current => stack.Peek();
public abstract DateTime Today { get; }
public abstract DateTime Now {get; }
public void Dispose()
{
if (this.GetType() != typeof(DefaultDateTimeProvider))
stack = stack.Pop();
}
// Not visible Default Implementation
private class DefaultDateTimeProvider : DateTimeProvider {
public override DateTime Today => DateTime.Today;
public override DateTime Now => DateTime.Now;
}
}
}
Here is how to use the above DateTimeProvider inside a Unit-Test
using System;
using Xunit;
namespace ambientcontext
{
public class TestDateTimeProvider
{
[Fact]
public void TestDateTime()
{
var actual = DateTimeProvider.Current.Today;
var expected = DateTime.Today;
Assert.Equal<DateTime>(expected, actual);
using (new MyDateTimeProvider(new DateTime(2012,12,21)))
{
Assert.Equal(2012, DateTimeProvider.Current.Today.Year);
using (new MyDateTimeProvider(new DateTime(1984,4,4)))
{
Assert.Equal(1984, DateTimeProvider.Current.Today.Year);
}
Assert.Equal(2012, DateTimeProvider.Current.Today.Year);
}
// Fall-Back to Default DateTimeProvider
Assert.Equal<int>(expected.Year, DateTimeProvider.Current.Today.Year);
}
private class MyDateTimeProvider : DateTimeProvider
{
private readonly DateTime dateTime;
public MyDateTimeProvider(DateTime dateTime):base()
{
this.dateTime = dateTime;
}
public override DateTime Today => this.dateTime.Date;
public override DateTime Now => this.dateTime;
}
}
}

asp:TextBox ReadOnly=true or Enabled=false?
I have a child aspx form that does an address lookup server side. The values from the child aspx page are then passed back to the parent textboxes via javascript client side.
Although you can see the textboxes have been changed neither ReadOnly or Enabled would allow the values to be posted back in the parent form.
ASP.NET MVC ActionLink and post method
If you're using ASP MVC3 you could use an Ajax.ActionLink(), that allows you to specify a HTTP Method which you could set to "POST".
How to hide reference counts in VS2013?
Workaround....
In VS 2015 Professional (and probably other versions). Go to Tools / Options / Environment / Fonts and Colours. In the "Show Settings For" drop-down, select "CodeLens" Choose the smallest font you can find e.g. Calibri 6. Change the foreground colour to your editor foreground colour (say "White") Click OK.
ASP.NET Core return JSON with status code
What I do in my Asp Net Core Api applications it is to create a class that extends from ObjectResult and provide many constructors to customize the content and the status code. Then all my Controller actions use one of the costructors as appropiate. You can take a look at my implementation at: https://github.com/melardev/AspNetCoreApiPaginatedCrud
and
https://github.com/melardev/ApiAspCoreEcommerce
here is how the class looks like(go to my repo for full code):
public class StatusCodeAndDtoWrapper : ObjectResult
{
public StatusCodeAndDtoWrapper(AppResponse dto, int statusCode = 200) : base(dto)
{
StatusCode = statusCode;
}
private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, string message) : base(dto)
{
StatusCode = statusCode;
if (dto.FullMessages == null)
dto.FullMessages = new List<string>(1);
dto.FullMessages.Add(message);
}
private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, ICollection<string> messages) : base(dto)
{
StatusCode = statusCode;
dto.FullMessages = messages;
}
}
Notice the base(dto) you replace dto by your object and you should be good to go.
Determine if running on a rooted device
Update 2017
You can do it now with Google Safetynet API. The SafetyNet API provides Attestation API which helps you assess the security and compatibility of the Android environments in which your apps run.
This attestation can helps to determine whether or not the particular device has been tampered with or otherwise modified.
The Attestation API returns a JWS response like this
{
"nonce": "R2Rra24fVm5xa2Mg",
"timestampMs": 9860437986543,
"apkPackageName": "com.package.name.of.requesting.app",
"apkCertificateDigestSha256": ["base64 encoded, SHA-256 hash of the
certificate used to sign requesting app"],
"apkDigestSha256": "base64 encoded, SHA-256 hash of the app's APK",
"ctsProfileMatch": true,
"basicIntegrity": true,
}
Parsing this response can help you determine if device is rooted or not
Rooted devices seem to cause ctsProfileMatch=false.
You can do it on client side but parsing response on server side is recommend. A basic client server archtecture with safety net API will look like this:-
What to do with branch after merge
After the merge, it's safe to delete the branch:
git branch -d branch1
Additionally, git will warn you (and refuse to delete the branch) if it thinks you didn't fully merge it yet. If you forcefully delete a branch (with git branch -D) which is not completely merged yet, you have to do some tricks to get the unmerged commits back though (see below).
There are some reasons to keep a branch around though. For example, if it's a feature branch, you may want to be able to do bugfixes on that feature still inside that branch.
If you also want to delete the branch on a remote host, you can do:
git push origin :branch1
This will forcefully delete the branch on the remote (this will not affect already checked-out repositiories though and won't prevent anyone with push access to re-push/create it).
git reflog shows the recently checked out revisions. Any branch you've had checked out in the recent repository history will also show up there. Aside from that, git fsck will be the tool of choice at any case of commit-loss in git.

Send response to all clients except sender
Here is a more complete answer about what has changed from 0.9.x to 1.x.
// send to current request socket client
socket.emit('message', "this is a test");// Hasn't changed
// sending to all clients, include sender
io.sockets.emit('message', "this is a test"); // Old way, still compatible
io.emit('message', 'this is a test');// New way, works only in 1.x
// sending to all clients except sender
socket.broadcast.emit('message', "this is a test");// Hasn't changed
// sending to all clients in 'game' room(channel) except sender
socket.broadcast.to('game').emit('message', 'nice game');// Hasn't changed
// sending to all clients in 'game' room(channel), include sender
io.sockets.in('game').emit('message', 'cool game');// Old way, DOES NOT WORK ANYMORE
io.in('game').emit('message', 'cool game');// New way
io.to('game').emit('message', 'cool game');// New way, "in" or "to" are the exact same: "And then simply use to or in (they are the same) when broadcasting or emitting:" from http://socket.io/docs/rooms-and-namespaces/
// sending to individual socketid, socketid is like a room
io.sockets.socket(socketid).emit('message', 'for your eyes only');// Old way, DOES NOT WORK ANYMORE
socket.broadcast.to(socketid).emit('message', 'for your eyes only');// New way

Node.js version on the command line? (not the REPL)
By default node package is nodejs, so use
$ nodejs -v
or
$ nodejs --version
You can make a link using
$ sudo ln -s /usr/bin/nodejs /usr/bin/node
then u can use
$ node --version
or
$ node -v
Viewing all defined variables
keep in mind dir() will return all current imports, AND variables.
if you just want your variables, I would suggest a naming scheme that is easy to extract from dir, such as varScore, varNames, etc.
that way, you can simply do this:
for vars in dir():
if vars.startswith("var"):
print vars
Edit
if you want to list all variables, but exclude imported modules and variables such as:
__builtins__
you can use something like so:
import os
import re
x = 11
imports = "os","re"
for vars in dir():
if vars.startswith("__") == 0 and vars not in imports:
print vars
as you can see, it will show the variable "imports" though, because it is a variable (well, a tuple). A quick workaround is to add the word "imports" into the imports tuple itself!

ListBox with ItemTemplate (and ScrollBar!)
I pasted your code into test project, added about 20 items and I get usable scroll bars, no problem, and they work as expected. When I only add a couple items (such that scrolling is unnecessary) I get no usable scrollbar. Could this be the case? that you are not adding enough items?
If you remove the ScrollViewer.VerticalScrollBarVisibility="Visible" then the scroll bars only appear when you have need of them.

How much does it cost to develop an iPhone application?
Appsamuck iPhone tutorials is aiming for 31 days of tutorials ending in 31 small apps developed for the iPhone all the source code for which is available to download. They also provide a commercial service to build apps!
If you want to know if you can do the coding, well at least you can download the code and see if anything there is helpful for your needs. On the flip side you can also get a quote from them for developing the app for you, so you can try both sides of the coin, outsource and in-house. Of course it all depends on how much time you have too! It's certainly worth a look!
(OK, after my last disastrous attempt to try and post a useful piece of help, I went off hunting around!)
Why does the C++ STL not provide any "tree" containers?
Reading through the answers here the common named reasons are that one cannot iterate through the tree or that the tree does not assume the similar interface to other STL containers and one could not use STL algorithms with such tree structure.
Having that in mind I tried to design my own tree data structure which will provide STL-like interface and will be usable with existing STL algorthims as much as possible.
My idea was that the tree must be based on the existing STL containers and that it must not hide the container, so that it will be accessible to use with STL algorithms.
The other important feature the tree must provide is the traversing iterators.
Here is what I was able to come up with: https://github.com/cppfw/utki/blob/master/src/utki/tree.hpp
And here are the tests: https://github.com/cppfw/utki/blob/master/tests/tree/tests.cpp
Finding the path of the program that will execute from the command line in Windows
Use the where command. The first result in the list is the one that will execute.
C:\> where notepad C:\Windows\System32\notepad.exe C:\Windows\notepad.exe
According to this blog post, where.exe is included with Windows Server 2003 and later, so this should just work with Vista, Win 7, et al.
On Linux, the equivalent is the which command, e.g. which ssh.
How to get complete month name from DateTime

How do I generate a list with a specified increment step?
The following example shows benchmarks for a few alternatives.
library(rbenchmark) # Note spelling: "rbenchmark", not "benchmark"
benchmark(seq(0,1e6,by=2),(0:5e5)*2,seq.int(0L,1e6L,by=2L))
## test replications elapsed relative user.self sys.self
## 2 (0:5e+05) * 2 100 0.587 3.536145 0.344 0.244
## 1 seq(0, 1e6, by = 2) 100 2.760 16.626506 1.832 0.900
## 3 seq.int(0, 1e6, by = 2) 100 0.166 1.000000 0.056 0.096
In this case, seq.int is the fastest method and seq the slowest. If performance of this step isn't that important (it still takes < 3 seconds to generate a sequence of 500,000 values), I might still use seq as the most readable solution.

How to redirect to Index from another controller?
You can use local redirect. Following codes are jumping the HomeController's Index page:
public class SharedController : Controller

if (btnLogout != null)
{
return LocalRedirect("~/Index");
}
return View();

How to run the Python program forever?
I have a small script interruptableloop.py that runs the code at an interval (default 1sec), it pumps out a message to the screen while it's running, and traps an interrupt signal that you can send with CTL-C:
#!/usr/bin/python3
from interruptableLoop import InterruptableLoop
loop=InterruptableLoop(intervalSecs=1) # redundant argument
while loop.ShouldContinue():
# some python code that I want
# to keep on running
pass
When you run the script and then interrupt it you see this output, (the periods pump out on every pass of the loop):
[py36]$ ./interruptexample.py

Why do I have ORA-00904 even when the column is present?
Have you compared the table definitions in Prod and Dev?
And when you are running it in SQL Developer, are you running the query in Prod (same database as the application) and with the same user?
If there are some additional columns that you are adding (using an alter command) and these changes are not yet promoted to prod, this issue is possible.
Can you post the definition of the table and your actual Query?

How would I create a UIAlertView in Swift?
SWIFT 4 : Simply create a extension to UIViewController as follows:
extension UIViewController {
func showSuccessAlert(withTitle title: String, andMessage message:String) {
let alert = UIAlertController(title: title, message: message,
preferredStyle: UIAlertController.Style.alert)
alert.addAction(UIAlertAction(title: "OK".localized, style:
UIAlertAction.Style.default, handler: nil))
self.present(alert, animated: true, completion: nil)
}
}
Now in your ViewController, directly call above function as if they are provided by UIViewController.
yourViewController.showSuccessAlert(withTitle:
"YourTitle", andMessage: "YourCustomTitle")

First you need to input the two numbers say num_rows and num_columns perhaps using argc and argv then do a for loop to print the dots.
int j=0;
int k=0;
for (k=0;k<num_columns;k++){
for (j=0;j<num_rows;j++){
printf(".");
}
printf("\n");
}
you'd have to replace the dot with something else later.
Cookies on localhost with explicit domain
localhost: You can use: domain: ".app.localhost" and it will work. The 'domain' parameter needs 1 or more dots in the domain name for setting cookies. Then you can have sessions working across localhost subdomains such as: api.app.localhost:3000.
Cast Object to Generic Type for returning
You have to use a Class instance because of the generic type erasure during compilation.
public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
try {
return clazz.cast(o);
} catch(ClassCastException e) {
return null;
}
}
The declaration of that method is:
public T cast(Object o)
This can also be used for array types. It would look like this:
final Class<int[]> intArrayType = int[].class;
final Object someObject = new int[]{1,2,3};
final int[] instance = convertInstanceOfObject(someObject, intArrayType);
Note that when someObject is passed to convertToInstanceOfObject it has the compile time type Object.

What are the valid Style Format Strings for a Reporting Services [SSRS] Expression?
You can set TextBox properties for setting negative number display and decimal places settings.
- Right-click the cell and then click Text Box Properties.
- Select Number, and in the Category field, click Currency.
Convert textbox text to integer
If your SQL database allows Null values for that field try using int? value like that :
if (this.txtboxname.Text == "" || this.txtboxname.text == null)
value = null;
else
value = Convert.ToInt32(this.txtboxname.Text);
Take care that Convert.ToInt32 of a null value returns 0 !
Convert.ToInt32(null) returns 0
How to add/update an attribute to an HTML element using JavaScript?
Obligatory jQuery solution. Finds and sets the title attribute to foo. Note this selects a single element since I'm doing it by id, but you could easily set the same attribute on a collection by changing the selector.
$('#element').attr( 'title', 'foo' );
Run jar file in command prompt
If you dont have an entry point defined in your manifest invoking java -jar foo.jar will not work.
Use this command if you dont have a manifest or to run a different main class than the one specified in the manifest:
java -cp foo.jar full.package.name.ClassName
See also instructions on how to create a manifest with an entry point: https://docs.oracle.com/javase/tutorial/deployment/jar/appman.html
R color scatter plot points based on values
Also it'd work to just specify ifelse() twice:
plot(pos,cn, col= ifelse(cn >= 3, "red", ifelse(cn <= 1,"blue", "black")), ylim = c(0, 10))
Why doesn't height: 100% work to expand divs to the screen height?
In order for a percentage value to work for height, the parent's height must be determined. The only exception is the root element <html>, which can be a percentage height. .
So, you've given all of your elements height, except for the <html>, so what you should do is add this:
html {
height: 100%;
}
And your code should work fine.
* { padding: 0; margin: 0; }_x000D_
html, body, #fullheight {_x000D_
min-height: 100% !important;_x000D_
height: 100%;_x000D_
}_x000D_
#fullheight {_x000D_
width: 250px;_x000D_
background: blue;_x000D_
}<div id=fullheight>_x000D_
Lorem Ipsum _x000D_
</div>How do I check that multiple keys are in a dict in a single pass?
In the case of determining whether only some keys match, this works:
any_keys_i_seek = ["key1", "key2", "key3"]
if set(my_dict).intersection(any_keys_i_seek):
# code_here
pass
Yet another option to find if only some keys match:
any_keys_i_seek = ["key1", "key2", "key3"]
if any_keys_i_seek & my_dict.keys():
# code_here
pass
Why am I getting "(304) Not Modified" error on some links when using HttpWebRequest?
This is intended behavior.
When you make an HTTP request, the server normally returns code 200 OK. If you set If-Modified-Since, the server may return 304 Not modified (and the response will not have the content). This is supposed to be your cue that the page has not been modified.
The authors of the class have foolishly decided that 304 should be treated as an error and throw an exception. Now you have to clean up after them by catching the exception every time you try to use If-Modified-Since.
Is it possible to set a number to NaN or infinity?
Yes, you can use numpy for that.
import numpy as np
a = arange(3,dtype=float)
a[0] = np.nan
a[1] = np.inf
a[2] = -np.inf
a # is now [nan,inf,-inf]
np.isnan(a[0]) # True
np.isinf(a[1]) # True
np.isinf(a[2]) # True

How to get Printer Info in .NET?
Please notice that the article that dowski and Panos was reffering to (MSDN Win32_Printer) can be a little misleading.
I'm referring the first value of most of the arrays. some begins with 1 and some begins with 0. for example, "ExtendedPrinterStatus" first value in table is 1, therefore, your array should be something like this:
string[] arrExtendedPrinterStatus = {
"","Other", "Unknown", "Idle", "Printing", "Warming Up",
"Stopped Printing", "Offline", "Paused", "Error", "Busy",
"Not Available", "Waiting", "Processing", "Initialization",
"Power Save", "Pending Deletion", "I/O Active", "Manual Feed"
};
and on the other hand, "ErrorState" first value in table is 0, therefore, your array should be something like this:
string[] arrErrorState = {
"Unknown", "Other", "No Error", "Low Paper", "No Paper", "Low Toner",
"No Toner", "Door Open", "Jammed", "Offline", "Service Requested",
"Output Bin Full"
};
BTW, "PrinterState" is obsolete, but you can use "PrinterStatus".
How to place Text and an Image next to each other in HTML?
img {
float:left;
}
h3 {
float:right;
}
Note that you will probably want to use the style clear:both on whatever elements comes after the code you provided so that it doesn't slide up directly beneath the floated elements.
Login to Microsoft SQL Server Error: 18456
18456 Error State List
ERROR STATE ERROR DESCRIPTION
- State 2 and State 5 Invalid userid
- State 6 Attempt to use a Windows login name with SQL Authentication
- State 7 Login disabled and password mismatch
- State 8 Password mismatch
- State 9 Invalid password
- State 11 and State 12 Valid login but server access failure
- State 13 SQL Server service paused
- State 18 Change password required
Potential causes Below is a list of reasons and some brief explanation what to do:
SQL Authentication not enabled: If you use SQL Login for the first time on SQL Server instance than very often error 18456 occurs because server might be set in Windows Authentication mode (only).
How to fix? Check this SQL Server and Windows Authentication Mode page.
Invalid userID: SQL Server is not able to find the specified UserID on the server you are trying to get. The most common cause is that this userID hasn’t been granted access on the server but this could be also a simple typo or you accidentally are trying to connect to different server (Typical if you use more than one server)
Invalid password: Wrong password or just a typo. Remember that this username can have different passwords on different servers.
less common errors: The userID might be disabled on the server. Windows login was provided for SQL Authentication (change to Windows Authentication. If you use SSMS you might have to run as different user to use this option). Password might have expired and probably several other reasons…. If you know of any other ones let me know.
18456 state 1 explanations: Usually Microsoft SQL Server will give you error state 1 which actually does not mean anything apart from that you have 18456 error. State 1 is used to hide actual state in order to protect the system, which to me makes sense. Below is a list with all different states and for more information about retrieving accurate states visit Understanding "login failed" (Error 18456) error messages in SQL Server 2005

Jquery open popup on button click for bootstrap
Give an ID to uniquely identify the button, lets say myBtn
// when DOM is ready
$(document).ready(function () {
// Attach Button click event listener
$("#myBtn").click(function(){
// show Modal
$('#myModal').modal('show');
});
});
Getting value of HTML text input
Yes, you can use jQuery to make this done, the idea is
Use a hidden value in your form, and copy the value from external text box to this hidden value just before submitting the form.
<form name="input" action="handle_email.php" method="post">
<input type="hidden" name="email" id="email" />
<input type="submit" value="Submit" />
</form>
<script>
$("form").submit(function() {
var emailFromOtherTextBox = $("#email_textbox").val();
$("#email").val(emailFromOtherTextBox );
return true;
});
</script>

java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.testing.models.Account
I had a similar exception (but different problem) - java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to org.bson.Document , and fortunately it's solved easier:
Instead of
List<Document> docs = obj.get("documents");
Document doc = docs.get(0)
which gives error on second line, One can use
List<Document> docs = obj.get("documents");
Document doc = new Document(docs.get(0));

How to Migrate to WKWebView?
WkWebView is much faster and reliable than UIWebview according to the Apple docs. Here, I posted my WkWebViewController.
import UIKit
import WebKit
class WebPageViewController: UIViewController,UINavigationControllerDelegate,UINavigationBarDelegate,WKNavigationDelegate{
var webView: WKWebView?
var webUrl="http://www.nike.com"
override func viewWillAppear(animated: Bool){
super.viewWillAppear(true)
navigationController!.navigationBar.hidden = false
}
override func viewDidLoad()
{
/* Create our preferences on how the web page should be loaded */
let preferences = WKPreferences()
preferences.javaScriptEnabled = false
/* Create a configuration for our preferences */
let configuration = WKWebViewConfiguration()
configuration.preferences = preferences
/* Now instantiate the web view */
webView = WKWebView(frame: view.bounds, configuration: configuration)
if let theWebView = webView{
/* Load a web page into our web view */
let url = NSURL(string: self.webUrl)
let urlRequest = NSURLRequest(URL: url!)
theWebView.loadRequest(urlRequest)
theWebView.navigationDelegate = self
view.addSubview(theWebView)
}
}

Update date + one year in mysql
This post helped me today, but I had to experiment to do what I needed. Here is what I found.
Should you want to add more complex time periods, for example 1 year and 15 days, you can use
UPDATE tablename SET datefieldname = curdate() + INTERVAL 15 DAY + INTERVAL 1 YEAR;
I found that using DATE_ADD doesn't allow for adding more than one interval. And there is no YEAR_DAYS interval keyword, though there are others that combine time periods. If you are adding times, use now() rather than curdate().

Where X is a variable that = the row number ( 415 )
Align button at the bottom of div using CSS
You can use position:absolute; to absolutely position an element within a parent div.
When using position:absolute; the element will be positioned absolutely from the first positioned parent div, if it can't find one it will position absolutely from the window so you will need to make sure the content div is positioned.
To make the content div positioned, all position values that aren't static will work, but relative is the easiest since it doesn't change the divs positioning by itself.
So add position:relative; to the content div, remove the float from the button and add the following css to the button:
position: absolute;
right: 0;
bottom: 0;
How to pause in C?
I assume you are on Windows. Instead of trying to run your program by double clicking on it's icon or clicking a button in your IDE, open up a command prompt, cd to the directory your program is in, and run it by typing its name on the command line.

How to catch segmentation fault in Linux?
On Linux we can have these as exceptions, too.
Normally, when your program performs a segmentation fault, it is sent a SIGSEGV signal. You can set up your own handler for this signal and mitigate the consequences. Of course you should really be sure that you can recover from the situation. In your case, I think, you should debug your code instead.
Back to the topic. I recently encountered a library (short manual) that transforms such signals to exceptions, so you can write code like this:
try
{
*(int*) 0 = 0;
}
catch (std::exception& e)
{
std::cerr << "Exception caught : " << e.what() << std::endl;
}
Didn't check it, though. Works on my x86-64 Gentoo box. It has a platform-specific backend (borrowed from gcc's java implementation), so it can work on many platforms. It just supports x86 and x86-64 out of the box, but you can get backends from libjava, which resides in gcc sources.
Printing Lists as Tabular Data
To create a simple table using terminaltables
Open the terminal or your command prompt and run pip install terminaltables
You can print and python list as the following
from terminaltables import AsciiTable
l = [
['Head', 'Head'],
['R1 C1', 'R1 C2'],
['R2 C1', 'R2 C2'],
['R3 C1', 'R3 C2']
]
table = AsciiTable(l)
print(table.table)
They have other cool tables don't forget to check them out. Just google their library.
Hope that helps :100:!

What is the dual table in Oracle?
I think this wikipedia article may help clarify.
http://en.wikipedia.org/wiki/DUAL_table
The DUAL table is a special one-row table present by default in all Oracle database installations. It is suitable for use in selecting a pseudocolumn such as SYSDATE or USER The table has a single VARCHAR2(1) column called DUMMY that has a value of "X"
Using XAMPP, how do I swap out PHP 5.3 for PHP 5.2?
I know this doesn't help you, but I have to say that this is one of the reasons I jumped from XAMPP to WampServer. WampServer lets you install multiple versions of PHP, Apache and/or MySQL, and switch between them all via a menu option.

Python's string interpolation is similar to C's printf()
If you try:

The tag %s will be replaced with the name variable. You should take a look to the print function tags: http://docs.python.org/library/functions.html
My kubernetes pods keep crashing with "CrashLoopBackOff" but I can't find any log
Whilst troubleshooting the same issue I found no logs when using kubeclt logs <pod_id>.
Therefore I ssh:ed in to the node instance to try to run the container using plain docker. To my surprise this failed also.
When entering the container with:
docker exec -it faulty:latest /bin/sh
and poking around I found that it wasn't the latest version.
A faulty version of the docker image was already available on the instance.
When I removed the faulty:latest instance with:
docker rmi faulty:latest
everything started to work.
Pass command parameter to method in ViewModel in WPF?
Just using Data Binding syntax. For example,

Not only can we use Data Binding to get some data from View Models, but also pass data back to View Models. In CommandParameter, must use ElementName to declare binding source explicitly.
How to add display:inline-block in a jQuery show() function?
actually jQuery simply clears the value of the 'display' property, and doesn't set it to 'block' (see internal implementation of jQuery.showHide()) -
function showHide(elements, show) {
var display, elem, hidden,
...
if (show) {
// Reset the inline display of this element to learn if it is
// being hidden by cascaded rules or not
if (!values[index] && display === "none") {
elem.style.display = "";
}
...
if (!show || elem.style.display === "none" || elem.style.display === "") {
elem.style.display = show ? values[index] || "" : "none";
}
}
Please note that you can override $.fn.show()/$.fn.hide(); storing original display in element itself when hiding (e.g. as an attribute or in the $.data()); and then applying it back again when showing.
Also, using css important! will probably not work here - since setting a style inline is usually stronger than any other rule

Using standard KeyboardEvent
As Joe comment it, KeyboardEvent is now the standard.
Same example to fire an enter (keyCode 13):
const ke = new KeyboardEvent('keydown', {
bubbles: true, cancelable: true, keyCode: 13
});
document.body.dispatchEvent(ke);
You can use this page help you to find the right keyboard event.
Outdated answer:
- initKeyboardEvent for IE9+, Chrome and Safari
- initKeyEvent for Firefox
You can do something like (here for Firefox)
var ev = document.createEvent('KeyboardEvent');
// Send key '13' (= enter)
ev.initKeyEvent(
'keydown', true, true, window, false, false, false, false, 13, 0);
document.body.dispatchEvent(ev);
Laravel 5.2 - Use a String as a Custom Primary Key for Eloquent Table becomes 0
This was added to the upgrade documentation on Dec 29, 2015, so if you upgraded before then you probably missed it.
When fetching any attribute from the model it checks if that column should be cast as an integer, string, etc.
By default, for auto-incrementing tables, the ID is assumed to be an integer in this method:
https://github.com/laravel/framework/blob/5.2/src/Illuminate/Database/Eloquent/Model.php#L2790
So the solution is:
class UserVerification extends Model
{
protected $primaryKey = 'your_key_name'; // or null
public $incrementing = false;
// In Laravel 6.0+ make sure to also set $keyType
protected $keyType = 'string';
}
WCF Error - Could not find default endpoint element that references contract 'UserService.UserService'

HTTP get with headers using RestTemplate
The RestTemplate getForObject() method does not support setting headers. The solution is to use the exchange() method.
So instead of restTemplate.getForObject(url, String.class, param) (which has no headers), use
HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...
HttpEntity entity = new HttpEntity(headers);
ResponseEntity<String> response = restTemplate.exchange(
url, HttpMethod.GET, entity, String.class, param);
Finally, use response.getBody() to get your result.
This question is similar to this question.
MySQL JDBC Driver 5.1.33 - Time Zone Issue
The connection string should be set like this:
jdbc:mysql://localhost/db?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
If you are defining the connection in an xml file (such as persistence.xml, standalone-full.xml, etc..), instead of & you should use & or use a CDATA block.
Stash only one file out of multiple files that have changed with Git?
Save the following code to a file, for example, named stash. Usage is stash <filename_regex>. The argument is the regular expression for the full path of the file. For example, to stash a/b/c.txt, stash a/b/c.txt or stash .*/c.txt, etc.
$ chmod +x stash
$ stash .*.xml
$ stash xyz.xml
Code to copy into the file:
#! /usr/bin/expect --
log_user 0
set filename_regexp [lindex $argv 0]
spawn git stash -p
for {} 1 {} {
expect {
-re "diff --git a/($filename_regexp) " {
set filename $expect_out(1,string)
}
"diff --git a/" {
set filename ""
}
"Stash this hunk " {
if {$filename == ""} {
send "n\n"
} else {

</script>
Place the following code in the code behind button click event.
string myclosescript = "<script language='javascript' type='text/javascript'>CloseWindow();</script>";
Page.ClientScript.RegisterStartupScript(GetType(), "myclosescript", myclosescript);
If you dont have any processing before close then you can directly put the following code in the ASPX itself in the button click tag.
OnClientClick="CloseWindow();"
Hope this helps.
A connection was successfully established with the server, but then an error occurred during the pre-login handshake
Had the same problem from many days. I had to explicitly add TLS1.2 support in my core project to address this error and it worked fine. ( ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;)

Bootstrap 3 - Set Container Width to 940px Maximum for Desktops?
There is a far easier solution (IMO) in Bootstrap 3 that does not require you to compile any custom LESS. You just have to leverage the cascade in "Cascading Style Sheets."
Set up your CSS loading like so...
<link type="text/css" rel="stylesheet" href="/css/bootstrap.css" />
<link type="text/css" rel="stylesheet" href="/css/custom.css" />
Where /css/custom.css is your unique style definitions. Inside that file, add the following definition...
@media (min-width: 1200px) {
.container {
width: 970px;
}
}
This will override Bootstrap's default width: 1170px setting when the viewport is 1200px or bigger.
Tested in Bootstrap 3.0.2
Find column whose name contains a specific string
This answer uses the DataFrame.filter method to do this without list comprehension:
import pandas as pd
data = {'spike-2': [1,2,3], 'hey spke': [4,5,6]}
df = pd.DataFrame(data)
print(df.filter(like='spike').columns)
Will output just 'spike-2'. You can also use regex, as some people suggested in comments above:
print(df.filter(regex='spike|spke').columns)
Will output both columns: ['spike-2', 'hey spke']
How do I iterate over a JSON structure?

C# How to change font of a label
I noticed there was not an actual full code answer, so as i come across this, i have created a function, that does change the font, which can be easily modified. I have tested this in
- XP SP3 and Win 10 Pro 64
private void SetFont(Form f, string name, int size, FontStyle style)
{
Font replacementFont = new Font(name, size, style);
f.Font = replacementFont;
}
Hint: replace Form to either Label, RichTextBox, TextBox, or any other relative control that uses fonts to change the font on them. By using the above function thus making it completely dynamic.
/// To call the function do this.
/// e.g in the form load event etc.
public Form1()
{
InitializeComponent();
SetFont(this, "Arial", 8, FontStyle.Bold);
// This sets the whole form and
// everything below it.
// Shaun Cassidy.
}
You can also, if you want a full libary so you dont have to code all the back end bits, you can download my dll from Github.
/// and then import the namespace
using Droitech.TextFont;
/// Then call it using:
TextFontClass fClass = new TextFontClass();
fClass.SetFont(this, "Arial", 8, FontStyle.Bold);
Simple.
How to use new PasswordEncoder from Spring Security
If you haven't actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.
It's a lot less hassle, as you don't have to worry about salt at all - the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it's also a standard which is compatible with applications using other languages.
There's really no reason to choose any of the other options for a new application.

Reading specific columns from a text file in python
You have a space delimited file, so use the module designed for reading delimited values files, csv.
import csv
with open('path/to/file.txt') as inf:
reader = csv.reader(inf, delimiter=" ")
second_col = list(zip(*reader))[1]
# In Python2, you can omit the `list(...)` cast
The zip(*iterable) pattern is useful for converting rows to columns or vice versa. If you're reading a file row-wise...
>>> testdata = [[1, 2, 3],
[4, 5, 6],
[7, 8, 9]]
>>> for line in testdata:
... print(line)
[1, 2, 3]
[4, 5, 6]
[7, 8, 9]
...but need columns, you can pass each row to the zip function
>>> testdata_columns = zip(*testdata)
# this is equivalent to zip([1,2,3], [4,5,6], [7,8,9])
>>> for line in testdata_columns:
... print(line)
[1, 4, 7]
[2, 5, 8]
[3, 6, 9]
Checking if type == list in python
Your issue is that you have re-defined list as a variable previously in your code. This means that when you do type(tmpDict[key])==list if will return False because they aren't equal.
That being said, you should instead use isinstance(tmpDict[key], list) when testing the type of something, this won't avoid the problem of overwriting list but is a more Pythonic way of checking the type.
Test if executable exists in Python?
I know that I'm being a bit of a necromancer here, but I stumbled across this question and the accepted solution didn't work for me for all cases Thought it might be useful to submit anyway. In particular, the "executable" mode detection, and the requirement of supplying the file extension. Furthermore, both python3.3's shutil.which (uses PATHEXT) and python2.4+'s distutils.spawn.find_executable (just tries adding '.exe') only work in a subset of cases.
So I wrote a "super" version (based on the accepted answer, and the PATHEXT suggestion from Suraj). This version of which does the task a bit more thoroughly, and tries a series of "broadphase" breadth-first techniques first, and eventually tries more fine-grained searches over the PATH space:
import os
import sys
import stat
import tempfile
def is_case_sensitive_filesystem():
tmphandle, tmppath = tempfile.mkstemp()
is_insensitive = os.path.exists(tmppath.upper())
os.close(tmphandle)
os.remove(tmppath)
return not is_insensitive
_IS_CASE_SENSITIVE_FILESYSTEM = is_case_sensitive_filesystem()
def which(program, case_sensitive=_IS_CASE_SENSITIVE_FILESYSTEM):
""" Simulates unix `which` command. Returns absolute path if program found """
def is_exe(fpath):
""" Return true if fpath is a file we have access to that is executable """
accessmode = os.F_OK | os.X_OK
if os.path.exists(fpath) and os.access(fpath, accessmode) and not os.path.isdir(fpath):
filemode = os.stat(fpath).st_mode
ret = bool(filemode & stat.S_IXUSR or filemode & stat.S_IXGRP or filemode & stat.S_IXOTH)
return ret
def list_file_exts(directory, search_filename=None, ignore_case=True):
""" Return list of (filename, extension) tuples which match the search_filename"""
if ignore_case:
search_filename = search_filename.lower()
for root, dirs, files in os.walk(path):
for f in files:
filename, extension = os.path.splitext(f)
if ignore_case:
filename = filename.lower()
if not search_filename or filename == search_filename:
yield (filename, extension)
break
fpath, fname = os.path.split(program)
# is a path: try direct program path
if fpath:
if is_exe(program):
return program
elif "win" in sys.platform:
# isnt a path: try fname in current directory on windows
if is_exe(fname):
return program
paths = [path.strip('"') for path in os.environ.get("PATH", "").split(os.pathsep)]
exe_exts = [ext for ext in os.environ.get("PATHEXT", "").split(os.pathsep)]
if not case_sensitive:
exe_exts = map(str.lower, exe_exts)
# try append program path per directory
for path in paths:
exe_file = os.path.join(path, program)
if is_exe(exe_file):
return exe_file
# try with known executable extensions per program path per directory
for path in paths:
filepath = os.path.join(path, program)
for extension in exe_exts:
exe_file = filepath+extension
if is_exe(exe_file):
return exe_file
# try search program name with "soft" extension search
if len(os.path.splitext(fname)[1]) == 0:
for path in paths:
file_exts = list_file_exts(path, fname, not case_sensitive)
for file_ext in file_exts:
filename = "".join(file_ext)
exe_file = os.path.join(path, filename)
if is_exe(exe_file):
return exe_file
return None
Usage looks like this:
>>> which.which("meld")
'C:\\Program Files (x86)\\Meld\\meld\\meld.exe'
The accepted solution did not work for me in this case, since there were files like meld.1, meld.ico, meld.doap, etc also in the directory, one of which were returned instead (presumably since lexicographically first) because the executable test in the accepted answer was incomplete and giving false positives.
How do I install the ext-curl extension with PHP 7?
Well I was able to install it by :
sudo apt-get install php-curl
on my system. This will install a dependency package, which depends on the default php version.
After that restart apache
sudo service apache2 restart
Remove last character of a StringBuilder?
Others have pointed out the deleteCharAt method, but here's another alternative approach:
String prefix = "";
for (String serverId : serverIds) {
sb.append(prefix);
prefix = ",";
sb.append(serverId);
}
Alternatively, use the Joiner class from Guava :)
As of Java 8, StringJoiner is part of the standard JRE.
Recording video feed from an IP camera over a network
about 3 years ago i needed cctv. I found zoneminder, tried to edit it to my liking, but found i was fixing it more than editing it.
Not to mention mp4 recording feature isn't actually part of the master branch (which is kind of lol, since its a cctv program and its already been about 3 years or more since it was suggested). Its literally just adapting the ffmpeg command lol.
So i found the solution!
If you want something done right, do it yourself.

File path for project files?
I was facing a similar issue, I had a file on my project, and wanted to test a class which had to deal with loading files from the FS and process them some way. What I did was:
- added the file
test.txtto my test project - on the solution explorer hit
alt-enter(file properties) - there I set
BuildActiontoContentandCopy to Output DirectorytoCopy if newer, I guessCopy alwayswould have done it as well
then on my tests I just had to Path.Combine(Environment.CurrentDirectory, "test.txt") and that's it. Whenever the project is compiled it will copy the file (and all it's parent path, in case it was in, say, a folder) to the bin\Debug (or whatever configuration you are using) folder.

Setting "checked" for a checkbox with jQuery
Plain JavaScript is very simple and much less overhead:

for(var i = 0; i < elements.length; i++)
{
elements[i].checked = true;
}
Java random number with given length
To generate a 6-digit number:
Use Random and nextInt as follows:
Random rnd = new Random();
int n = 100000 + rnd.nextInt(900000);
Note that n will never be 7 digits (1000000) since nextInt(900000) can at most return 899999.
So how do I randomize the last 5 chars that can be either A-Z or 0-9?
Here's a simple solution:
// Generate random id, for example 283952-V8M32
char[] chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".toCharArray();
Random rnd = new Random();
StringBuilder sb = new StringBuilder((100000 + rnd.nextInt(900000)) + "-");
for (int i = 0; i < 5; i++)
sb.append(chars[rnd.nextInt(chars.length)]);
return sb.toString();

Each time you do e.nextElement() you skip one. So you skip two elements in each iteration of your loop.

How to wait in bash for several subprocesses to finish and return exit code !=0 when any subprocess ends with code !=0?
To parallelize this...
for i in $(whatever_list) ; do
do_something $i
done
Translate it to this...
for i in $(whatever_list) ; do echo $i ; done | ## execute in parallel...
(
export -f do_something ## export functions (if needed)
export PATH ## export any variables that are required
xargs -I{} --max-procs 0 bash -c ' ## process in batches...
{
echo "processing {}" ## optional
do_something {}
}'
)
- If an error occurs in one process, it won't interrupt the other processes, but it will result in a non-zero exit code from the sequence as a whole.
- Exporting functions and variables may or may not be necessary, in any particular case.
- You can set
--max-procsbased on how much parallelism you want (0means "all at once"). - GNU Parallel offers some additional features when used in place of
xargs-- but it isn't always installed by default. - The
forloop isn't strictly necessary in this example sinceecho $iis basically just regenerating the output of$(whatever_list). I just think the use of theforkeyword makes it a little easier to see what is going on. - Bash string handling can be confusing -- I have found that using single quotes works best for wrapping non-trivial scripts.
- You can easily interrupt the entire operation (using ^C or similar), unlike the the more direct approach to Bash parallelism.
Here's a simplified working example...
for i in {0..5} ; do echo $i ; done |xargs -I{} --max-procs 2 bash -c '
{
echo sleep {}
sleep 2s
}'
Search a whole table in mySQL for a string
Try something like this:
SELECT * FROM clients WHERE CONCAT(field1, '', field2, '', fieldn) LIKE "%Mary%"
You may want to see SQL docs for additional information on string operators and regular expressions.
Edit: There may be some issues with NULL fields, so just in case you may want to use IFNULL(field_i, '') instead of just field_i
Case sensitivity: You can use case insensitive collation or something like this:
... WHERE LOWER(CONCAT(...)) LIKE LOWER("%Mary%")
Just search all field: I believe there is no way to make an SQL-query that will search through all field without explicitly declaring field to search in. The reason is there is a theory of relational databases and strict rules for manipulating relational data (something like relational algebra or codd algebra; these are what SQL is from), and theory doesn't allow things such as "just search all fields". Of course actual behaviour depends on vendor's concrete realisation. But in common case it is not possible. To make sure, check SELECT operator syntax (WHERE section, to be precise).
Getting the docstring from a function
On ipython or jupyter notebook, you can use all the above mentioned ways, but i go with
my_func?
or
?my_func
for quick summary of both method signature and docstring.
I avoid using
my_func??
(as commented by @rohan) for docstring and use it only to check the source code
URLEncoder not able to translate space character
A space is encoded to %20 in URLs, and to + in forms submitted data (content type application/x-www-form-urlencoded). You need the former.
Using Guava:
dependencies {
compile 'com.google.guava:guava:23.0'
// or, for Android:
compile 'com.google.guava:guava:23.0-android'
}
You can use UrlEscapers:
String encodedString = UrlEscapers.urlFragmentEscaper().escape(inputString);
Don't use String.replace, this would only encode the space. Use a library instead.
SQL Not Like Statement not working
mattgcon,
Should work, do you get more rows if you run the same SQL with the "NOT LIKE" line commented out? If not, check the data. I know you mentioned in your question, but check that the actual SQL statement is using that clause. The other answers with NULL are also a good idea.
ADB Install Fails With INSTALL_FAILED_TEST_ONLY
Looks like you need to modify your AndroidManifest.xml
Change android:testOnly="true" to android:testOnly="false" or remove this attribute.
If you want to keep the attribute android:testOnly as true you can use pm install command with -t option, but you may need to push the apk to device first.
$ adb push bin/hello.apk /tmp/
5210 KB/s (825660 bytes in 0.154s)
$ adb shell pm install /tmp/hello.apk
pkg: /tmp/hello.apk
Failure [INSTALL_FAILED_TEST_ONLY]
$ adb shell pm install -t /tmp/hello.apk
pkg: /tmp/hello.apk
Success
I was able to reproduce the same issue and the above solved it.
If your APK is outside the device (on your desktop), then below command would do it:
$ adb install -t hello.apk
ng-change get new value and original value

Auto-size dynamic text to fill fixed size container
I didn't find any of the previous solutions to be adequate enough due to bad performance, so I made my own that uses simple math instead of looping. Should work fine in all browsers as well.

VBA code to set date format for a specific column as "yyyy-mm-dd"
It works, when you use both lines:
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000") = Format(Date, "yyyy-mm-dd")
Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000").NumberFormat = "yyyy-mm-dd"
Which method performs better: .Any() vs .Count() > 0?
It depends, how big is the data set and what are your performance requirements?
If it's nothing gigantic use the most readable form, which for myself is any, because it's shorter and readable rather than an equation.

Get the current date in java.sql.Date format
tl;dr
myPreparedStatement.setObject( // Directly exchange java.time objects with database without the troublesome old java.sql.* classes.
… ,
LocalDate.parse( // Parse string as a `LocalDate` date-only value.
"2018-01-23" // Input string that complies with standard ISO 8601 formatting.
)
)
java.time
The modern approach uses the java.time classes that supplant the troublesome old legacy classes such as java.util.Date and java.sql.Date.
For a date-only value, use LocalDate. The LocalDate class represents a date-only value without time-of-day and without time zone.
The java.time classes use standard formats when parsing/generating strings. So no need to specify a formatting pattern.
LocalDate ld = LocalDate.parse( input ) ;
You can directly exchange java.time objects with your database using a JDBC driver compliant with JDBC 4.2 or later. You can forget about transforming in and out of java.sql.* classes.
myPreparedStatement.setObject( … , ld ) ;
Retrieval:
LocalDate ld = myResultSet.getObject( … , LocalDate.class ) ;
About java.time
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
Where to obtain the java.time classes?
- Java SE 8, Java SE 9, and later
- Built-in.
- Part of the standard Java API with a bundled implementation.
- Java 9 adds some minor features and fixes.
- Java SE 6 and Java SE 7
- Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
- Android
- Later versions of Android bundle implementations of the java.time classes.
- For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.
How do I concatenate strings with variables in PowerShell?
You could use the PowerShell equivalent of String.Format - it's usually the easiest way to build up a string. Place {0}, {1}, etc. where you want the variables in the string, put a -f immediately after the string and then the list of variables separated by commas.
Get-ChildItem c:\code|%{'{0}\{1}\{2}.dll' -f $_.fullname,$buildconfig,$_.name}
(I've also taken the dash out of the $buildconfig variable name as I have seen that causes issues before too.)
Spring Boot not serving static content
In my case I have a spring boot application which is kind of mixing spring and jaxrs. So I have a java class which inherits from the class org.glassfish.jersey.server.ResourceConfig. I had to add this line to the constructor of that class so that the spring endpoints are still called: property(ServletProperties.FILTER_FORWARD_ON_404, true).
Where does the .gitignore file belong?
Root directory is fine for placing the .gitignore file.
Don't forget to use git rm --cached FILENAME to add files to .gitignore if you have created the gitignore file after you committed the repo with a file you want ignored. See github docs. I found this out when I created a .env file, then committed it, then tried it to ignore it by creating a .gitignore file.

Use FtpWebRequest, only if you need a greater control, that WebClient does not offer (like TLS/SSL encryption, progress monitoring, ascii/text transfer mode, resuming transfers, etc). Easy way is to just copy an FTP response stream to FileStream using Stream.CopyTo:
FtpWebRequest request =
(FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;
using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(@"C:\local\path\file.zip"))
{
ftpStream.CopyTo(fileStream);
}
Progress monitoring
If you need to monitor a download progress, you have to copy the contents by chunks yourself:
FtpWebRequest request =
(FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;
using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(@"C:\local\path\file.zip"))
{
byte[] buffer = new byte[10240];
int read;
while ((read = ftpStream.Read(buffer, 0, buffer.Length)) > 0)
{
fileStream.Write(buffer, 0, read);
Console.WriteLine("Downloaded {0} bytes", fileStream.Position);
}
}

How to pass data in the ajax DELETE request other than headers
I was able to successfully pass through the data attribute in the ajax method. Here is my code
$.ajax({
url: "/api/Gigs/Cancel",
type: "DELETE",
data: {
"GigId": link.attr('data-gig-id')
}
})
The link.attr method simply returned the value of 'data-gig-id' .
Is there a way to include commas in CSV columns without breaking the formatting?
I found that some applications like Numbers in Mac ignore the double quote if there is space before it.
a, "b,c" doesn't work while a,"b,c" works.
Android 5.0 - Add header/footer to a RecyclerView
recyclerview:1.2.0 introduces ConcatAdapter class which concatenates multiple adapters into a single one. So it allows to create separate header/footer adapters and reuse them across multiple lists.
myRecyclerView.adapter = ConcatAdapter(headerAdapter, listAdapter, footerAdapter)
Take a look at the announcement article. It contains a sample how to display a loading progress in header and footer using ConcatAdapter.
For the moment when I post this answer the version 1.2.0 of the library is in alpha stage, so the api might change. You can check the status here.
Push an associative item into an array in JavaScript
To make something like associative array in JavaScript you have to use objects. ?
var obj = {}; // {} will create an object
var name = "name";
var val = 2;
obj[name] = val;
console.log(obj);How do you create a custom AuthorizeAttribute in ASP.NET Core?
The modern way is AuthenticationHandlers
in startup.cs add
services.AddAuthentication("BasicAuthentication").AddScheme<AuthenticationSchemeOptions, BasicAuthenticationHandler>("BasicAuthentication", null);
public class BasicAuthenticationHandler : AuthenticationHandler<AuthenticationSchemeOptions>
{
private readonly IUserService _userService;
public BasicAuthenticationHandler(
IOptionsMonitor<AuthenticationSchemeOptions> options,
ILoggerFactory logger,
UrlEncoder encoder,
ISystemClock clock,
IUserService userService)
: base(options, logger, encoder, clock)
{
_userService = userService;
}
protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
{
if (!Request.Headers.ContainsKey("Authorization"))
return AuthenticateResult.Fail("Missing Authorization Header");
User user = null;
try
{
var authHeader = AuthenticationHeaderValue.Parse(Request.Headers["Authorization"]);
var credentialBytes = Convert.FromBase64String(authHeader.Parameter);
var credentials = Encoding.UTF8.GetString(credentialBytes).Split(new[] { ':' }, 2);
var username = credentials[0];
var password = credentials[1];
user = await _userService.Authenticate(username, password);
}
catch
{
return AuthenticateResult.Fail("Invalid Authorization Header");
}
if (user == null)
return AuthenticateResult.Fail("Invalid User-name or Password");
var claims = new[] {
new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
new Claim(ClaimTypes.Name, user.Username),
};
var identity = new ClaimsIdentity(claims, Scheme.Name);
var principal = new ClaimsPrincipal(identity);
var ticket = new AuthenticationTicket(principal, Scheme.Name);
return AuthenticateResult.Success(ticket);
}
}
IUserService is a service that you make where you have user name and password. basically it returns a user class that you use to map your claims on.
var claims = new[] {
new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
new Claim(ClaimTypes.Name, user.Username),
};
Then you can query these claims and her any data you mapped, ther are quite a few, have a look at ClaimTypes class
you can use this in an extension method an get any of the mappings
public int? GetUserId()
{
if (context.User.Identity.IsAuthenticated)
{
var id=context.User.FindFirst(ClaimTypes.NameIdentifier);
if (!(id is null) && int.TryParse(id.Value, out var userId))
return userId;
}
return new Nullable<int>();
}
This new way, i think is better than the old way as shown here, both work
public class BasicAuthenticationAttribute : AuthorizationFilterAttribute
{
public override void OnAuthorization(HttpActionContext actionContext)
{
if (actionContext.Request.Headers.Authorization != null)
{
var authToken = actionContext.Request.Headers.Authorization.Parameter;
// decoding authToken we get decode value in 'Username:Password' format
var decodeauthToken = System.Text.Encoding.UTF8.GetString(Convert.FromBase64String(authToken));
// spliting decodeauthToken using ':'
var arrUserNameandPassword = decodeauthToken.Split(':');
// at 0th postion of array we get username and at 1st we get password
if (IsAuthorizedUser(arrUserNameandPassword[0], arrUserNameandPassword[1]))
{
// setting current principle
Thread.CurrentPrincipal = new GenericPrincipal(new GenericIdentity(arrUserNameandPassword[0]), null);
}
else
{
actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized);
}
}
else
{
actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized);
}
}
public static bool IsAuthorizedUser(string Username, string Password)
{
// In this method we can handle our database logic here...
return Username.Equals("test") && Password == "test";
}
}

Bootstrap control with multiple "data-toggle"
There is a nice solution using class .stretched-link. Button must have a class .position-relative. Here is a full working example:
Tooltip must be added to the button otherwise its position will be incorrect.

I didn't find this suggestion here so here it goes: if your project has more than one target (ie one for OSX and one for iOS) then you must link the relevant libraries for each target.. so for example in my case I needed AudioToolbox.. I had to add it once for OSX and once for iOS (under the frameworks folder, you must have a duplicate of each library for each target.. if you see only one.. then that's a red flag)
How to connect wireless network adapter to VMWare workstation?
Since there is only one WiFi hardware on the computer its not possible to connect one WiFi hardware to multiple WiFi networks, if you want to that I think you have to map WiFi hardware to guest OS and how host you'll have to use some other hardware (may be Ethernet) but I'm sure that it will work in that way as no VM software allow us to allocate Hardware to Guest except for USB, you can also get USB WiFI and allocate that to VM only.

python multithreading wait till all threads finished
You need to use join method of Thread object in the end of the script.
t1 = Thread(target=call_script, args=(scriptA + argumentsA))
t2 = Thread(target=call_script, args=(scriptA + argumentsB))
t3 = Thread(target=call_script, args=(scriptA + argumentsC))
t1.start()
t2.start()
t3.start()
t1.join()
t2.join()
t3.join()
Thus the main thread will wait till t1, t2 and t3 finish execution.
In Swift how to call method with parameters on GCD main thread?
Here's the nicer (IMO) Swifty/Cocoa style syntax to achieve the same result as the other answers:
NSOperationQueue.mainQueue().addOperationWithBlock({
// Your code here
})
Or you could grab the popular Async Swift library for even less code and more functionality:
Async.main {
// Your code here
}
Unable to launch the IIS Express Web server
I had the exact same problem.
The reason - bad IIS config file.
Try deleting the automatically-created IISExpress folder, which is usually located at %userprofile%/Documents, e.g. C:\Users\[you]\Documents\IISExpress.
Don't worry, VS should create it again - correctly, this time - once you run your solution again.
EDIT: Command line for deleting the folder:
rmdir /s /q "%userprofile%\Documents\IISExpress"
python .replace() regex
You can use the re module for regexes, but regexes are probably overkill for what you want. I might try something like
z.write(article[:article.index("</html>") + 7]
This is much cleaner, and should be much faster than a regex based solution.
How to enumerate an enum
I think this is more efficient than other suggestions because GetValues() is not called each time you have a loop. It is also more concise. And you get a compile-time error, not a runtime exception if Suit is not an enum.
EnumLoop<Suit>.ForEach((suit) => {
DoSomethingWith(suit);
});
EnumLoop has this completely generic definition:
class EnumLoop<Key> where Key : struct, IConvertible {
static readonly Key[] arr = (Key[])Enum.GetValues(typeof(Key));
static internal void ForEach(Action<Key> act) {
for (int i = 0; i < arr.Length; i++) {
act(arr[i]);
}
}
}
Using Transactions or SaveChanges(false) and AcceptAllChanges()?
With the Entity Framework most of the time SaveChanges() is sufficient. This creates a transaction, or enlists in any ambient transaction, and does all the necessary work in that transaction.
Sometimes though the SaveChanges(false) + AcceptAllChanges() pairing is useful.
The most useful place for this is in situations where you want to do a distributed transaction across two different Contexts.
I.e. something like this (bad):
using (TransactionScope scope = new TransactionScope())
{
//Do something with context1
//Do something with context2
//Save and discard changes
context1.SaveChanges();
//Save and discard changes
context2.SaveChanges();
//if we get here things are looking good.
scope.Complete();
}
If context1.SaveChanges() succeeds but context2.SaveChanges() fails the whole distributed transaction is aborted. But unfortunately the Entity Framework has already discarded the changes on context1, so you can't replay or effectively log the failure.
But if you change your code to look like this:
using (TransactionScope scope = new TransactionScope())
{
//Do something with context1
//Do something with context2
//Save Changes but don't discard yet
context1.SaveChanges(false);
//Save Changes but don't discard yet
context2.SaveChanges(false);
//if we get here things are looking good.
scope.Complete();
context1.AcceptAllChanges();
context2.AcceptAllChanges();
}
While the call to SaveChanges(false) sends the necessary commands to the database, the context itself is not changed, so you can do it again if necessary, or you can interrogate the ObjectStateManager if you want.
This means if the transaction actually throws an exception you can compensate, by either re-trying or logging state of each contexts ObjectStateManager somewhere.
Drag and drop menuitems
jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div (or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.
In Gradle, is there a better way to get Environment Variables?
In android gradle 0.4.0 you can just do:

How to execute Ant build in command line
Go to the Ant website and download. This way, you have a copy of Ant outside of Eclipse. I recommend to put it under the C:\ant directory. This way, it doesn't have any spaces in the directory names. In your System Control Panel, set the Environment Variable ANT_HOME to this directory, then pre-pend to the System PATHvariable, %ANT_HOME%\bin. This way, you don't have to put in the whole directory name.
Assuming you did the above, try this:
C:\> cd \Silk4J\Automation\iControlSilk4J
C:\Silk4J\Automation\iControlSilk4J> ant -d build
This will do several things:
- It will eliminate the possibility that the problem is with Eclipe's version of Ant.
- It is way easier to type
- Since you're executing the
build.xmlin the directory where it exists, you don't end up with the possibility that your Ant build can't locate a particular directory.
The -d will print out a lot of output, so you might want to capture it, or set your terminal buffer to something like 99999, and run cls first to clear out the buffer. This way, you'll capture all of the output from the beginning in the terminal buffer.
Let's see how Ant should be executing. You didn't specify any targets to execute, so Ant should be taking the default build target. Here it is:
<target depends="build-subprojects,build-project" name="build"/>
The build target does nothing itself. However, it depends upon two other targets, so these will be called first:
The first target is build-subprojects:
<target name="build-subprojects"/>
This does nothing at all. It doesn't even have a dependency.
The next target specified is build-project does have code:
<target depends="init" name="build-project">
This target does contain tasks, and some dependent targets. Before build-project executes, it will first run the init target:
<target name="init">
<mkdir dir="bin"/>
<copy includeemptydirs="false" todir="bin">
<fileset dir="src">
<exclude name="**/*.java"/>
</fileset>
</copy>
</target>
This target creates a directory called bin, then copies all files under the src tree with the suffix *.java over to the bin directory. The includeemptydirs mean that directories without non-java code will not be created.
Ant uses a scheme to do minimal work. For example, if the bin directory is created, the <mkdir/> task is not executed. Also, if a file was previously copied, or there are no non-Java files in your src directory tree, the <copy/> task won't run. However, the init target will still be executed.
Next, we go back to our previous build-project target:
<target depends="init" name="build-project">
<echo message="${ant.project.name}: ${ant.file}"/>
<javac debug="true" debuglevel="${debuglevel}" destdir="bin" source="${source}" target="${target}">
<src path="src"/>
<classpath refid="iControlSilk4J.classpath"/>
</javac>
</target>
Look at this line:
<echo message="${ant.project.name}: ${ant.file}"/>
That should have always executed. Did your output print:
[echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml
Maybe you didn't realize that was from your build.
After that, it runs the <javac/> task. That is, if there's any files to actually compile. Again, Ant tries to avoid work it doesn't have to do. If all of the *.java files have previously been compiled, the <javac/> task won't execute.
And, that's the end of the build. Your build might not have done anything simply because there was nothing to do. You can try running the clean task, and then build:
C:\Silk4J\Automation\iControlSilk4J> ant -d clean build
However, Ant usually prints the target being executed. You should have seen this:
init:
build-subprojects:
build-projects:
[echo] iControlSilk4J: C:\Silk4J\Automation\iControlSilk4J\build.xml
build:
Build Successful
Note that the targets are all printed out in order they're executed, and the tasks are printed out as they are executed. However, if there's nothing to compile, or nothing to copy, then you won't see these tasks being executed. Does this look like your output? If so, it could be there's nothing to do.
- If the
bindirectory already exists,<mkdir/>isn't going to execute. - If there are no non-Java files in
src, or they have already been copied intobin, the<copy/>task won't execute. - If there are no Java file in your
srcdirectory, or they have already been compiled, the<java/>task won't run.
If you look at the output from the -d debug, you'll see Ant looking at a task, then explaining why a particular task wasn't executed. Plus, the debug option will explain how Ant decides what tasks to execute.
See if that helps.

Val and Var in Kotlin
In Kotlin, we have two types of variables: var or val. The first one, var, is a mutable reference (read-write) that can be updated after initialization. The var keyword is used to define a variable in Kotlin. It is equivalent to a normal (nonfinal) Java variable. If our variable needs to change at some time, we should declare it using the var keyword. Let's look at an example of a variable declaration:
fun main(args: Array<String>) {
var fruit:String = "orange" // 1
fruit = "banana" // 2
}
