Also check that
<modules>
<remove name="FormsAuthentication"/>
</modules>
If you found anything like this just remove:
<remove name="FormsAuthentication"/>
Line from web.config and here you go it will work fine I have tested it.
Clearly HttpContext.Current
is not null
only if you access it in a thread that handles incoming requests. That's why it works "when i use this code in another class of a page".
It won't work in the scheduling related class because relevant code is not executed on a valid thread, but a background thread, which has no HTTP context associated with.
Overall, don't use Application["Setting"]
to store global stuffs, as they are not global as you discovered.
If you need to pass certain information down to business logic layer, pass as arguments to the related methods. Don't let your business logic layer access things like HttpContext
or Application["Settings"]
, as that violates the principles of isolation and decoupling.
Update:
Due to the introduction of async/await
it is more often that such issues happen, so you might consider the following tip,
In general, you should only call HttpContext.Current
in only a few scenarios (within an HTTP module for example). In all other cases, you should use
Page.Context
https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.page.context?view=netframework-4.7.2 Controller.HttpContext
https://docs.microsoft.com/en-us/dotnet/api/system.web.mvc.controller.httpcontext?view=aspnet-mvc-5.2instead of HttpContext.Current
.
I also had this problem recently. Working with a new client, trying to get a an old web forms app running from Visual Studio, with IISExpress using Windows Authentication. For me, the web.config was correctly configured
However, the IISExpress.config settings file had:
<windowsAuthentication enabled="false">
The user account the developer was logged in was very new, so unlikely it had been edited. Simple fix it turned out, change this to enabled=true and it all ran as it should then.
Below Test Init will also do the job.
[TestInitialize]
public void TestInit()
{
HttpContext.Current = new HttpContext(new HttpRequest(null, "http://tempuri.org", null), new HttpResponse(null));
YourControllerToBeTestedController = GetYourToBeTestedController();
}
The Host
property will return the domain name you used when accessing the site. So, in your development environment, since you're requesting
http://localhost:950/m/pages/Searchresults.aspx?search=knife&filter=kitchen
It's returning localhost
. You can break apart your URL like so:
Protocol: http
Host: localhost
Port: 950
PathAndQuery: /m/pages/SearchResults.aspx?search=knight&filter=kitchen
Milox solution is better than the accepted one IMHO but I had some problems with this implementation when handling urls with querystring.
I made some changes to make it work properly with any urls and to avoid Reflection.
public static HttpContext FakeHttpContext(string url)
{
var uri = new Uri(url);
var httpRequest = new HttpRequest(string.Empty, uri.ToString(),
uri.Query.TrimStart('?'));
var stringWriter = new StringWriter();
var httpResponse = new HttpResponse(stringWriter);
var httpContext = new HttpContext(httpRequest, httpResponse);
var sessionContainer = new HttpSessionStateContainer("id",
new SessionStateItemCollection(),
new HttpStaticObjectsCollection(),
10, true, HttpCookieMode.AutoDetect,
SessionStateMode.InProc, false);
SessionStateUtility.AddHttpSessionStateToContext(
httpContext, sessionContainer);
return httpContext;
}
try it proxy package.json add code:
"proxy":"https://localhost:port"
and restart npm enjoy
same code
const instance = axios.create({
baseURL: "/api/list",
});
You'd be much better off using the same array with both lists, and creating angular filters to achieve your goal.
http://docs.angularjs.org/guide/dev_guide.templates.filters.creating_filters
Rough, untested code follows:
appModule.filter('checked', function() {
return function(input, checked) {
if(!input)return input;
var output = []
for (i in input){
var item = input[i];
if(item.checked == checked)output.push(item);
}
return output
}
});
and the view (i added an "uncheck" button too)
<div id="AddItem">
<h3>Add Item</h3>
<input value="1" type="number" placeholder="1" ng-model="itemAmount">
<input value="" type="text" placeholder="Name of Item" ng-model="itemName">
<br/>
<button ng-click="addItem()">Add to list</button>
</div>
<!-- begin: LIST OF CHECKED ITEMS -->
<div id="CheckedList">
<h3>Checked Items: {{getTotalCheckedItems()}}</h3>
<h4>Checked:</h4>
<table>
<tr ng-repeat="item in items | checked:true" class="item-checked">
<td><b>amount:</b> {{item.amount}} -</td>
<td><b>name:</b> {{item.name}} -</td>
<td>
<i>this item is checked!</i>
<button ng-click="item.checked = false">uncheck item</button>
</td>
</tr>
</table>
</div>
<!-- end: LIST OF CHECKED ITEMS -->
<!-- begin: LIST OF UNCHECKED ITEMS -->
<div id="UncheckedList">
<h3>Unchecked Items: {{getTotalItems()}}</h3>
<h4>Unchecked:</h4>
<table>
<tr ng-repeat="item in items | checked:false" class="item-unchecked">
<td><b>amount:</b> {{item.amount}} -</td>
<td><b>name:</b> {{item.name}} -</td>
<td>
<button ng-click="item.checked = true">check item</button>
</td>
</tr>
</table>
</div>
<!-- end: LIST OF ITEMS -->
Then you dont need the toggle methods etc in your controller
In the project I'm working on, audit log also started from the very minimalistic design, like the one you described:
event ID
event date/time
event type
user ID
description
The idea was the same: to keep things simple.
However, it quickly became obvious that this minimalistic design was not sufficient. The typical audit was boiling down to questions like this:
Who the heck created/updated/deleted a record
with ID=X in the table Foo and when?
So, in order to be able to answer such questions quickly (using SQL), we ended up having two additional columns in the audit table
object type (or table name)
object ID
That's when design of our audit log really stabilized (for a few years now).
Of course, the last "improvement" would work only for tables that had surrogate keys. But guess what? All our tables that are worth auditing do have such a key!
df['name'].value_counts()[:5].sort_values(ascending=False)
The value_counts
will return a count object of pandas.core.series.Series
and sort_values(ascending=False)
will get you the highest values first.
You haven't actually asked a question, but assuming you have one, this could be your answer...
Assuming all characters, except the "Special Characters" are allowed you can write
String regex = "^[^<>'\"/;`%]*$";
Give in the xml file of your layout android:scaleType="fitXY"
P.S : this applies to when the image is set with android:src="..."
rather than android:background="..."
as backgrounds are set by default to stretch and fit to the View.
Convert the string to an InputStream and pass it to DocumentBuilder
final InputStream stream = new ByteArrayInputStream(string.getBytes(StandardCharsets.UTF_8));
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
builder.parse(stream);
EDIT
In response to bendin's comment regarding encoding, see shsteimer's answer to this question.
I'm a Ubuntu user and I had the same issue, when I was trying to run python script through a bash script while files were located in a NTFS partition (even with su didn't work) then I've moved it home (ext4) then it worked.
An example of use :
You consume many classes that have a commun property 'CreationDate' :
public class Contact
{
// some properties
public DateTime CreationDate { get; set; }
}
public class Company
{
// some properties
public DateTime CreationDate { get; set; }
}
public class Opportunity
{
// some properties
public DateTime CreationDate { get; set; }
}
If you write a commun method that retrieves the value of the 'CreationDate' Property, you'd have to use reflection:
static DateTime RetrieveValueOfCreationDate(Object item)
{
return (DateTime)item.GetType().GetProperty("CreationDate").GetValue(item);
}
With the 'dynamic' concept, your code is much more elegant :
static DateTime RetrieveValueOfCreationDate(dynamic item)
{
return item.CreationDate;
}
Something like this should work.
ssh [email protected] 'find -type f -name "*.pdf" -exec cp {} ./pdfsfolder \;'
I like to share a revelation that I had. When you build a project, Intellij Idea runs a java process that resides in its core(ex: C:\Program Files\JetBrains\IntelliJ IDEA 2020.3\jbr\bin). The "build process heap size", as mentioned by many others, changes the heap size of this java process. However, the main java process is triggered later by the Idea's java process, hence have different VM arguments. I noticed that the max heap size of this process is 1/3 of the Idea's java process, while min heap is the half of max(1/6). To round up:
When you set 9g heap on "build process heap size" the actual heap size for the compiler is max 3g and min 1,5g. And no need for restart is neccessary.
PS: tested on version 2020.3

What about .GlobalEnv$a <- "new"
? I saw this explicit way of creating a variable in a certain environment here: http://adv-r.had.co.nz/Environments.html. It seems shorter than using the assign()
function.
nput from a terminal never really "ends" (unless the device is disconnected), but it is useful to enter more than one "file" into a terminal, so a key sequence is reserved to indicate end of input. In UNIX the translation of the keystroke to EOF is performed by the terminal driver, so a program does not need to distinguish terminals from other input files. By default, the driver converts a Control-D character at the start of a line into an end-of-file indicator. To insert an actual Control-D (ASCII 04) character into the input stream, the user precedes it with a "quote" command character (usually Control-V). AmigaDOS is similar but uses Control-\ instead of Control-D.
In Microsoft's DOS and Windows (and in CP/M and many DEC operating systems), reading from the terminal will never produce an EOF. Instead, programs recognize that the source is a terminal (or other "character device") and interpret a given reserved character or sequence as an end-of-file indicator; most commonly this is an ASCII Control-Z, code 26. Some MS-DOS programs, including parts of the Microsoft MS-DOS shell (COMMAND.COM) and operating-system utility programs (such as EDLIN), treat a Control-Z in a text file as marking the end of meaningful data, and/or append a Control-Z to the end when writing a text file. This was done for two reasons:
Backward compatibility with CP/M. The CP/M file system only recorded the lengths of files in multiples of 128-byte "records", so by convention a Control-Z character was used to mark the end of meaningful data if it ended in the middle of a record. The MS-DOS filesystem has always recorded the exact byte-length of files, so this was never necessary on MS-DOS.
It allows programs to use the same code to read input from both a terminal and a text file.
following will show one table of dataset
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = "TableName"; // table name you need to show
if you want to show multiple tables, you need to create one datatable or custom object collection out of all tables.
if two tables with same table schema
dtAll = dtOne.Copy(); // dtOne = ds.Tables[0]
dtAll.Merge(dtTwo); // dtTwo = dtOne = ds.Tables[1]
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ; // datatable
sample code to mode all tables
DataTable dtAll = ds.Tables[0].Copy();
for (var i = 1; i < ds.Tables.Count; i++)
{
dtAll.Merge(ds.Tables[i]);
}
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ;

Looking at RFC3986 - Uniform Resource Identifier (URI): Generic Syntax, your question revolves around the path component of a URI.
foo://example.com:8042/over/there?name=ferret#nose \_/ \______________/\_________/ \_________/ \__/ | | | | | scheme authority path query fragment | _____________________|__ / \ / \ urn:example:animal:ferret:nose
Citing section 3.3, valid characters for a URI segment
are of type pchar
:
pchar = unreserved / pct-encoded / sub-delims / ":" / "@"
Which breaks down to:
ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded
"!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "="
":" / "@"
Or in other words: You may use any (non-control-) character from the ASCII table, except /
, ?
, #
, [
and ]
.
This understanding is backed by RFC1738 - Uniform Resource Locators (URL).
From the documentation, you can apparently use either command to keep the file in the project history. Looks like you want remove, since it also deletes the file from the working directory.
From the Mercurial book at http://hgbook.red-bean.com/read/:
Removing a file does not affect its history. It is important to understand that removing a file has only two effects. It removes the current version of the file from the working directory. It stops Mercurial from tracking changes to the file, from the time of the next commit. Removing a file does not in any way alter the history of the file.
The man page hg(1) says this about forget:
Mark the specified files so they will no longer be tracked after the next commit. This only removes files from the current branch, not from the entire project history, and it does not delete them from the working directory.
And this about remove:
Schedule the indicated files for removal from the repository. This only removes files from the current branch, not from the entire project history.
CASE is the answer, but you will need to have a separate case statement for each column you want returned. As long as the WHERE clause is the same, there won't be much benefit separating it out into multiple queries.
Example:
SELECT
CASE @var
WHEN 'xyz' THEN col1
WHEN 'zyx' THEN col2
ELSE col7
END,
CASE @var
WHEN 'xyz' THEN col2
WHEN 'zyx' THEN col3
ELSE col8
END
FROM Table

I use explicit interface implementation most of the time. Here are the main reasons.
Refactoring is safer
When changing an interface, it's better if the compiler can check it. This is harder with implicit implementations.
Two common cases come to mind:
Adding a function to an interface, where an existing class that implements this interface already happens to have a method with the same signature as the new one. This can lead to unexpected behavior, and has bitten me hard several times. It's difficult to "see" when debugging because that function is likely not located with the other interface methods in the file (the self-documenting issue mentioned below).
Removing a function from an interface. Implicitly implemented methods will be suddenly dead code, but explicitly implemented methods will get caught by compile error. Even if the dead code is good to keep around, I want to be forced to review it and promote it.
It's unfortunate that C# doesn't have a keyword that forces us to mark a method as an implicit implementation, so the compiler could do the extra checks. Virtual methods don't have either of the above problems due to required use of 'override' and 'new'.
Note: for fixed or rarely-changing interfaces (typically from vendor API's), this is not a problem. For my own interfaces, though, I can't predict when/how they will change.
It's self-documenting
If I see 'public bool Execute()' in a class, it's going to take extra work to figure out that it's part of an interface. Somebody will probably have to comment it saying so, or put it in a group of other interface implementations, all under a region or grouping comment saying "implementation of ITask". Of course, that only works if the group header isn't offscreen..
Whereas: 'bool ITask.Execute()' is clear and unambiguous.
Clear separation of interface implementation
I think of interfaces as being more 'public' than public methods because they are crafted to expose just a bit of the surface area of the concrete type. They reduce the type to a capability, a behavior, a set of traits, etc. And in the implementation, I think it's useful to keep this separation.
As I am looking through a class's code, when I come across explicit interface implementations, my brain shifts into "code contract" mode. Often these implementations simply forward to other methods, but sometimes they will do extra state/param checking, conversion of incoming parameters to better match internal requirements, or even translation for versioning purposes (i.e. multiple generations of interfaces all punting down to common implementations).
(I realize that publics are also code contracts, but interfaces are much stronger, especially in an interface-driven codebase where direct use of concrete types is usually a sign of internal-only code.)
Related: Reason 2 above by Jon.
And so on
Plus the advantages already mentioned in other answers here:
It's not all fun and happiness. There are some cases where I stick with implicits:
Also, it can be a pain to do the casting when you do in fact have the concrete type and want to call an explicit interface method. I deal with this in one of two ways:
public IMyInterface I { get { return this; } }
(which should get inlined) and call foo.I.InterfaceMethod()
. If multiple interfaces that need this ability, expand the name beyond I (in my experience it's rare that I have this need).If you want to make sure the HTML file doesn't contain any PHP code and will not be executed as PHP, do not use include
or require
. Simply do:
echo file_get_contents("/path/to/file.html");
I use the ffmpeg-python
binding. You can find more information here.
import ffmpeg
(
ffmpeg
.input('/path/to/jpegs/*.jpg', pattern_type='glob', framerate=25)
.output('movie.mp4')
.run()
)
textarea {
overflow-y: scroll; /* Vertical scrollbar */
overflow: scroll; /* Horizontal and vertical scrollbar*/
}
The safest way to do this is to prompt for the password beforehand and then pipe it into the command. Prompting for the password will avoid having the password saved anywhere in your code and it also won't show up in your bash history. Here's an example:
from getpass import getpass
from subprocess import Popen, PIPE
password = getpass("Please enter your password: ")
# sudo requires the flag '-S' in order to take input from stdin
proc = Popen("sudo -S apach2ctl restart".split(), stdin=PIPE, stdout=PIPE, stderr=PIPE)
# Popen only accepts byte-arrays so you must encode the string
proc.communicate(password.encode())
I also faced the same problem but my case was a bit different the ones above. I tried to open a project created in a different computer. I found that the path to package folder is not updated when you add a reference so restarting VS, changing .NET version, or any mentioned recommendation does not solve the problem. I opened the csproj file in notepad++ and corrected all the relative paths to packages folder. Then; all the warnings are gone. Hope it helps.
If you have to select the id:
DELETE FROM table WHERE id IN (SELECT id FROM somewhere_else)
If you already know them (and they are not in the thousands):
DELETE FROM table WHERE id IN (?,?,?,?,?,?,?,?)
I found when doing this that in order to set the gravity to center, and still have your password hint show when using inputType
, the android:gravity="Center"
must be at the end of your XML line.
<EditText android:textColor="#000000" android:id="@+id/editText2"
android:layout_width="fill_parent" android:hint="Password"
android:background="@drawable/rounded_corner"
android:layout_height="fill_parent"
android:nextFocusDown="@+id/imageButton1"
android:nextFocusRight="@+id/imageButton1"
android:nextFocusLeft="@+id/editText1"
android:nextFocusUp="@+id/editText1"
android:inputType="textVisiblePassword"
android:textColorHint="#999999"

Use path.join http://nodejs.org/docs/v0.4.10/api/path.html#path.join
var path = require("path"),
fs = require("fs");
fs.readFile(path.join(__dirname, '..', '..', 'foo.bar'));
path.join()
will handle leading/trailing slashes for you and just do the right thing and you don't have to try to remember when trailing slashes exist and when they dont.
Your line:
img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.
Try
cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
Check pandas.__version__
:
In [76]: import pandas as pd
In [77]: pd.__version__
Out[77]: '0.12.0-933-g281dc4e'
Pandas also provides a utility function, pd.show_versions()
, which reports the version of its dependencies as well:
In [53]: pd.show_versions(as_json=False)

In SQL Server Management Studio I can easily create a SELECT
query:
SELECT Contact.Naam_Contactpersoon, Bedrijf.BedrijfsNaam, Bedrijf.Adres, Bedrijf.Postcode
FROM Contact
INNER JOIN Bedrijf ON Bedrijf.IDBedrijf = Contact.IDbedrijf
I can execute it, and all my contacts are shown.
Now change the SELECT
to a DELETE
:
DELETE Contact
FROM Contact
INNER JOIN Bedrijf ON Bedrijf.IDBedrijf = Contact.IDbedrijf
All the records you saw in the SELECT
statement will be removed.
You may even create a more difficult inner join with the same procedure, for example:
DELETE FROM Contact
INNER JOIN Bedrijf ON Bedrijf.IDBedrijf = Contact.IDbedrijf
INNER JOIN LoginBedrijf ON Bedrijf.IDLoginBedrijf = LoginBedrijf.IDLoginBedrijf
That is so basic that I am wondering what book you are using to study? Try
data[1, "V1"] # row first, quoted column name second, and case does matter
Further note: Terminology in discussing R can be crucial and sometimes tricky. Using the term "table" to refer to that structure leaves open the possibility that it was either a 'table'-classed, or a 'matrix'-classed, or a 'data.frame'-classed object. The answer above would succeed with any of them, while @BenBolker's suggestion below would only succeed with a 'data.frame'-classed object.
I am unrepentant in my phrasing despite the recent downvote. There is a ton of free introductory material for beginners in R: https://cran.r-project.org/other-docs.html
gzip > stdin.gz
perhaps? Otherwise, you need to flesh out your question.
Use as.integer
:
set.seed(1)
x <- runif(5, 0, 100)
x
[1] 26.55087 37.21239 57.28534 90.82078 20.16819
as.integer(x)
[1] 26 37 57 90 20
Test for class:
xx <- as.integer(x)
str(xx)
int [1:5] 26 37 57 90 20
The general rule I follow is not to include any header file unless I have to. So unless I am storing the object of a class as a member variable of my class I won't include it, I'll just use the forward declaration.
An alternative to substr
is to split the string into a list of single characters and process that:
N <- 2
sapply(strsplit(x, ""), function(x, n) paste(tail(x, n), collapse = ""), N)
There are JDK versions available from the base CentOS repositories. Depending on your version of CentOS, and the JDK you want to install, the following as root should give you what you want:
OpenJDK Runtime Environment (Java SE 6)
yum install java-1.6.0-openjdk
OpenJDK Runtime Environment (Java SE 7)
yum install java-1.7.0-openjdk
OpenJDK Development Environment (Java SE 7)
yum install java-1.7.0-openjdk-devel
OpenJDK Development Environment (Java SE 6)
yum install java-1.6.0-openjdk-devel
Update for Java 8
In CentOS 6.6 or later, Java 8 is available. Similar to 6 and 7 above, the packages are as follows:
OpenJDK Runtime Environment (Java SE 8)
yum install java-1.8.0-openjdk
OpenJDK Development Environment (Java SE 8)
yum install java-1.8.0-openjdk-devel
There's also a 'headless' JRE package that is the same as the above JRE, except it doesn't contain audio/video support. This can be used for a slightly more minimal installation:
OpenJDK Runtime Environment - Headless (Java SE 8)
yum install java-1.8.0-openjdk-headless
There are two solutions of this issue:
The first solution is add a constructor to your component and bind your function like bellow:
constructor(props) {
super(props);
...
this.delta = this.delta.bind(this);
}
So do this:
this.delta = this.delta.bind(this);
Instead of this:
this.delta.bind(this);
The second solution is to use an arrow function instead:
delta = () => {
this.setState({
count : this.state.count++
});
}
Actually arrow function DOES NOT bind it’s own this
. Arrow Functions lexically bind
their context so this
actually refers to the originating context.
For more information about bind function:
Bind function Understanding JavaScript Bind ()
For more information about arrow function:
don't give this in file input value="123".
$(document).ready(function(){
var img = $('#uploadPicture').val();
});
Since all lists are already "sorted" by the order the items were added (FIFO ordering), you can "resort" them with another order, including the natural ordering of elements, using java.util.Collections.sort()
.
EDIT:
Lists as data structures are based in what is interesting is the ordering in which the items where inserted.
Sets do not have that information.
If you want to order by adding time, use List
. If you want to order by other criteria, use SortedSet
.
You'll need to use a static
readonly
list instead. And if you want the list to be immutable then you might want to consider using ReadOnlyCollection<T>
rather than List<T>
.
private static readonly ReadOnlyCollection<string> _metrics =
new ReadOnlyCollection<string>(new[]
{
SourceFile.LOC,
SourceFile.MCCABE,
SourceFile.NOM,
SourceFile.NOA,
SourceFile.FANOUT,
SourceFile.FANIN,
SourceFile.NOPAR,
SourceFile.NDC,
SourceFile.CALLS
});
public static ReadOnlyCollection<string> Metrics
{
get { return _metrics; }
}
You can use scalar multiplication to modify each element in your vector.
> r <- 0:10
> r <- r * 2
> r
[1] 0 2 4 6 8 10 12 14 16 18 20
or
> r <- 0:10 * 2
> r
[1] 0 2 4 6 8 10 12 14 16 18 20
I have a python 2 and python 3 version of this code. I know that the question was asked for python 2 but now (8 years later lol) people will probably be using python 3.
Python 3 Code:
import random
number = str(random.randint(1, 10000000))
comma_placement = 4
print('The original number is: {}. '.format(number))
while True:
if len(number) % 3 == 0:
for i in range(0, len(number) // 3 - 1):
number = number[0:len(number) - comma_placement + 1] + ',' + number[len(number) - comma_placement + 1:]
comma_placement = comma_placement + 4
else:
for i in range(0, len(number) // 3):
number = number[0:len(number) - comma_placement + 1] + ',' + number[len(number) - comma_placement + 1:]
break
print('The new and improved number is: {}'.format(number))
Python 2 Code: (Edit. The python 2 code isn't working. I am thinking that the syntax is different).

The explicit way of saying "search until X
but not including X
" is:
(?:(?!X).)*
where X
can be any regular expression.
In your case, though, this might be overkill - here the easiest way would be
[^z]*
This will match anything except z
and therefore stop right before the next z
.
So .*?quick[^z]*
will match The quick fox jumps over the la
.
However, as soon as you have more than one simple letter to look out for, (?:(?!X).)*
comes into play, for example
(?:(?!lazy).)*
- match anything until the start of the word lazy
.
This is using a lookahead assertion, more specifically a negative lookahead.
.*?quick(?:(?!lazy).)*
will match The quick fox jumps over the
.
Explanation:
(?: # Match the following but do not capture it:
(?!lazy) # (first assert that it's not possible to match "lazy" here
. # then match any character
)* # end of group, zero or more repetitions.
Furthermore, when searching for keywords, you might want to surround them with word boundary anchors: \bfox\b
will only match the complete word fox
but not the fox in foxy
.
Note
If the text to be matched can also include linebreaks, you will need to set the "dot matches all" option of your regex engine. Usually, you can achieve that by prepending (?s)
to the regex, but that doesn't work in all regex engines (notably JavaScript).
Alternative solution:
In many cases, you can also use a simpler, more readable solution that uses a lazy quantifier. By adding a ?
to the *
quantifier, it will try to match as few characters as possible from the current position:
.*?(?=(?:X)|$)
will match any number of characters, stopping right before X
(which can be any regex) or the end of the string (if X
doesn't match). You may also need to set the "dot matches all" option for this to work. (Note: I added a non-capturing group around X
in order to reliably isolate it from the alternation)
The required SQL will be some like:-
SELECT * FROM cd
LEFT JOIN ab ON ab.sht = cd.sht
LEFT JOIN aa ON aa.sht = cd.sht
....
Hope it helps.
it is easy! you are downloading the binary file?. download the rpm latest package openssl-1.0.1e-30.el6.x86_64 check what was the current version using rpm -q openssl. if this is older then do rpm -U openssl-1.0.1e-30.el6.x86_64 . if yum is configured updated this package in the repo and do yum update openssl if your repo in RHN do simply yum update openssl-1.0.1g is very old and valnuarable

There might be many causes to this problem. The key is to use
export QT_DEBUG_PLUGINS=1
before you run your Qt application. Then, inspect the output, which will point you to the direction of the error. In my case it was:
Cannot load library /opt/nao/plugins/platforms/libqxcb.so: (/opt/nao/bin/../lib/libz.so.1: version `ZLIB_1.2.9' not found (required by /usr/lib/x86_64-linux-gnu/libpng16.so.16))

In my system (Ubuntu 12.04) I found RESET QUERY CACHE
and even restarting mysql server not enough. This was due to memory disc caching.
After each query, I clean the disc cache in the terminal:

and then reset the query cache in mysql client:
RESET QUERY CACHE;
You can't add a border, but this would work for the same effect. You could also make the UIView called blackBG in this example into a UIImageView with a border image and a blank middle, and then you'd have a custom image border instead of just black.
UIView *blackBG = [[UIView alloc] initWithFrame:CGRectMake(0,0,100,100)];
blackBG.backgroundColor = [UIColor blackColor];
UIImageView *myPicture = [[UIImageView alloc] initWithImage:
[UIImage imageNamed: @"myPicture.jpg"]];
int borderWidth = 10;
myPicture.frame = CGRectMake(borderWidth,
borderWidth,
blackBG.frame.size.width-borderWidth*2,
blackBG.frame.size.height-borderWidth*2)];
[blackBG addSubview: myPicture];

I would use a ByteArrayOutputStream
. And on finish you can call:
new String( baos.toByteArray(), codepage );
or better:
baos.toString( codepage );
For the String
constructor, the codepage
can be a String
or an instance of java.nio.charset.Charset. A possible value is java.nio.charset.StandardCharsets.UTF_8.
The method toString()
accepts only a String
as a codepage
parameter (stand Java 8).
$.each($("#MySelect option"), function(){
alert($(this).text() + " - " + $(this).val());
});
Use this code to open the submenu on mousehover (desktop only):
$('ul.nav li.dropdown').hover(function () {
if ($(window).width() > 767) {
$(this).find('.dropdown-menu').show();
}
}, function () {
if ($(window).width() > 767) {
$(this).find('.dropdown-menu').hide().css('display','');
}
});
And if you want the first level menu to be clickable, even on mobile add this:
$('.dropdown-toggle').click(function() {
if ($(this).next('.dropdown-menu').is(':visible')) {
window.location = $(this).attr('href');
}
});
The submenu (dropdown-menu) will be opened with mousehover on desktop, and with click/touch on mobile and tablet.
Once the submenu was open, a second click will let you open the link.
Thanks to the if ($(window).width() > 767)
, the submenu will take the full screen width on mobile.

I got this error while trying to copy an object. I fixed it by encoding the copySource. This is actually described in the method documentation:
Params: copySource – The name of the source bucket and key name of the source object, separated by a slash (/). Must be URL-encoded.
CopyObjectRequest objectRequest = CopyObjectRequest.builder()
.copySource(URLEncoder.encode(bucket + "/" + oldFileKey, "UTF-8"))
.destinationBucket(bucket)
.destinationKey(newFileKey)
.build();
If you are getting this message from a Maven built war change the scope of the JDBC driver to provided, and put a copy of it in the lib directory. Like this:

<version>5.1.18</version>
<!-- put a copy in /usr/share/tomcat7/lib -->

For what its worth: A decimal number, is a decimal number, you either round it to some other value or not. Internally, it will approximate a decimal fraction according to the rule of floating point arthmetic and handling. It stays a decimal number (floating point, in JS a double) internally, no matter how you many digits you want to display it with.
To present it for display, you can choose the precision of the display to whatever you want by string conversion. Presentation is a display issue, not a storage thing.
They might be just a \r
or a \n
. I just checked and the text visualizer in VS 2010 displays both as newlines as well as \r\n
.
This string
string test = "blah\r\nblah\rblah\nblah";
Shows up as
blah
blah
blah
blah
in the text visualizer.
So you could try
string modifiedString = originalString
.Replace(Environment.NewLine, "<br />")
.Replace("\r", "<br />")
.Replace("\n", "<br />");
I tried Chandra's answer but my server configuration does not allow file_get_contents()
PHP Warning: file_get_contents() URL file-access is disabled in the server configuration

$forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
$remote = $_SERVER['REMOTE_ADDR'];
$country = "Unknown";
if(filter_var($client, FILTER_VALIDATE_IP))
{
$ip = $client;
}
elseif(filter_var($forward, FILTER_VALIDATE_IP))
{
$ip = $forward;

Hope that helps ;-)
When the file is writing in binary(byte by byte),create FileStream and above solutions Not working,because file is ready and wrotted in every bytes,so in this Situation you need other workaround like this: Do this when file created or you want to start processing on file
long fileSize = 0;
currentFile = new FileInfo(path);
while (fileSize < currentFile.Length)//check size is stable or increased
{
fileSize = currentFile.Length;//get current size
System.Threading.Thread.Sleep(500);//wait a moment for processing copy
currentFile.Refresh();//refresh length value
}
//Now file is ready for any process!
In python many things are iterable including files and strings. Iterating over a filehandler gives you a list of all the lines in that file. Iterating over a string gives you a list of all the characters in that string.
charsFromFile = []
filePath = r'path\to\your\file.txt' #the r before the string lets us use backslashes
for line in open(filePath):
for char in line:
charsFromFile.append(char)
#apply code on each character here
or if you want a one liner
#the [0] at the end is the line you want to grab.
#the [0] can be removed to grab all lines
[list(a) for a in list(open('test.py'))][0]
.
.
Edit: as agf mentions you can use itertools.chain.from_iterable
His method is better, unless you want the ability to specify which lines to grab
list(itertools.chain.from_iterable(open(filename, 'rU)))
This does however require one to be familiar with itertools, and as a result looses some readablity
If you only want to iterate over the chars, and don't care about storing a list, then I would use the nested for loops. This method is also the most readable.
Use an AJAX Request on your PHP file, then display the result on your page, without any reloading.
http://api.jquery.com/load/ This is a simple solution if you don't need any POST data.
From version 9.1.4 you only need to import ReactiveFormsModule
you can wrap reserved words in square brackets to avoid these kinds of errors:
dbo.TableName.[Date]
By the Spring guys, used for Grails reloading but works with Java too:
It's probably more than solved. Just want to contribute with another simple solution:
var text = 'uololooo';
// With ES6
[...text].forEach(c => console.log(c))
// With the `of` operator
for (const c of text) {
console.log(c)
}
// With ES5
for (var x = 0, c=''; c = text.charAt(x); x++) {
console.log(c);
}
// ES5 without the for loop:
text.split('').forEach(function(c) {
console.log(c);
});
I just wrote a blog post on saving an object's data to Binary, XML, or Json. You are correct that you must decorate your classes with the [Serializable] attribute, but only if you are using Binary serialization. You may prefer to use XML or Json serialization. Here are the functions to do it in the various formats. See my blog post for more details.

From a purely "make it fit in the div" perspective, add the following to your table class (jsfiddle):
table-layout: fixed;
width: 100%;
Set your column widths as desired; otherwise, the fixed layout algorithm will distribute the table width evenly across your columns.
For quick reference, here are the table layout algorithms, emphasis mine:
With this (fast) algorithm, the horizontal layout of the table does not depend on the contents of the cells; it only depends on the table's width, the width of the columns, and borders or cell spacing.
In this algorithm (which generally requires no more than two passes), the table's width is given by the width of its columns [, as determined by content] (and intervening borders).
[...] This algorithm may be inefficient since it requires the user agent to have access to all the content in the table before determining the final layout and may demand more than one pass.
Click through to the source documentation to see the specifics for each algorithm.
ArrayList<Customer> custArr = new ArrayList<Customer>();
while(youWantToContinue) {
//get a customerName
//get an amount
custArr.add(new Customer(customerName, amount);
}
For this to work... you'll have to fix your constructor...
Assuming your Customer
class has variables called name
and sale
, your constructor should look like this:
public Customer(String customerName, double amount) {
name = customerName;
sale = amount;
}
Change your Store
class to something more like this:
public class Store {
private ArrayList<Customer> custArr;
public new Store() {
custArr = new ArrayList<Customer>();
}
public void addSale(String customerName, double amount) {
custArr.add(new Customer(customerName, amount));
}
public Customer getSaleAtIndex(int index) {
return custArr.get(index);
}
//or if you want the entire ArrayList:
public ArrayList getCustArr() {
return custArr;
}
}
You could have searched just for whereIn
function in the core to see that. Here you are. This must answer all your questions
/**

*/
public function whereIn($column, $values, $boolean = 'and', $not = false)
{
$type = $not ? 'NotIn' : 'In';
// If the value of the where in clause is actually a Closure, we will assume that
// the developer is using a full sub-select for this "in" statement, and will
// execute those Closures, then we can re-construct the entire sub-selects.
if ($values instanceof Closure)
{
return $this->whereInSub($column, $values, $boolean, $not);
}
$this->wheres[] = compact('type', 'column', 'values', 'boolean');
$this->bindings = array_merge($this->bindings, $values);
return $this;
}
Look that it has a third boolean param. Good luck.
Just posting in case it help someone else. The cause of this error for me was a missing do
after creating a form with form_with
. Hope that may help someone else
The %#08X
conversion must precede the value with 0X
; that is required by the standard. There's no evidence in the standard that the #
should alter the behaviour of the 08
part of the specification except that the 0X
prefix is counted as part of the length (so you might want/need to use %#010X
. If, like me, you like your hex presented as 0x1234CDEF
, then you have to use 0x%08X
to achieve the desired result. You could use %#.8X
and that should also insert the leading zeroes.
Try variations on the following code:
#include <stdio.h>
int main(void)
{
int j = 0;
printf("0x%.8X = %#08X = %#.8X = %#010x\n", j, j, j, j);
for (int i = 0; i < 8; i++)
{
j = (j << 4) | (i + 6);
printf("0x%.8X = %#08X = %#.8X = %#010x\n", j, j, j, j);
}
return(0);
}
On an RHEL 5 machine, and also on Mac OS X (10.7.5), the output was:
0x00000000 = 00000000 = 00000000 = 0000000000
0x00000006 = 0X000006 = 0X00000006 = 0x00000006
0x00000067 = 0X000067 = 0X00000067 = 0x00000067
0x00000678 = 0X000678 = 0X00000678 = 0x00000678
0x00006789 = 0X006789 = 0X00006789 = 0x00006789
0x0006789A = 0X06789A = 0X0006789A = 0x0006789a
0x006789AB = 0X6789AB = 0X006789AB = 0x006789ab
0x06789ABC = 0X6789ABC = 0X06789ABC = 0x06789abc
0x6789ABCD = 0X6789ABCD = 0X6789ABCD = 0x6789abcd
I'm a little surprised at the treatment of 0; I'm not clear why the 0X
prefix is omitted, but with two separate systems doing it, it must be standard. It confirms my prejudices against the #
option.
The treatment of zero is according to the standard.
ISO/IEC 9899:2011 §7.21.6.1 The
fprintf
function¶6 The flag characters and their meanings are:
...
#
The result is converted to an "alternative form". ... Forx
(orX
) conversion, a nonzero result has0x
(or0X
) prefixed to it. ...
(Emphasis added.)
Note that using %#X
will use upper-case letters for the hex digits and 0X
as the prefix; using %#x
will use lower-case letters for the hex digits and 0x
as the prefix. If you prefer 0x
as the prefix and upper-case letters, you have to code the 0x
separately: 0x%X
. Other format modifiers can be added as needed, of course.
For printing addresses, use the <inttypes.h>
header and the uintptr_t
type and the PRIXPTR
format macro:
#include <inttypes.h>
#include <stdio.h>
int main(void)
{
void *address = &address; // &address has type void ** but it converts to void *
printf("Address 0x%.12" PRIXPTR "\n", (uintptr_t)address);
return 0;
}
Example output:
Address 0x7FFEE5B29428
Choose your poison on the length — I find that a precision of 12 works well for addresses on a Mac running macOS. Combined with the .
to specify the minimum precision (digits), it formats addresses reliably. If you set the precision to 16, the extra 4 digits are always 0 in my experience on the Mac, but there's certainly a case to be made for using 16 instead of 12 in portable 64-bit code (but you'd use 8 for 32-bit code).

Just my 2 cents on setting PHPSESSID cookie issue when on localhost and under dev environment. I make the AJAX call to my REST API endpoint on the locahost. Say its address is mysite.localhost/api/member/login/
(virtal host on my dev environment).
When I do this request on Postman, things go fine and PHPSESSID is set with the response.
When I request this endpoint via AJAX from the Browsersync proxied page (e.g. from 122.133.1.110:3000/test/api/login.php
in my browser address line, see the domain is different vs mysite.localhost
) PHPSESSID does not appear among cookies.
When I make this request directly from the page on the same domain (i.e. mysite.localhost/test/api/login.php
) PHPSESSID is set just fine.
So this is a cross-origin origin request cookies issue as mentioned in @flu answer above
To add to @user3303020 answer and output the search results into a file, you can run

I don't think a message box is the best way to go with this as you would need the VB code running in a loop to check the cell contents, or unless you plan to run the macro manually. In this case I think it would be better to add conditional formatting to the cell to change the background to red (for example) if the value exceeds the upper limit.
I think it depends on how you installed python. Note that you can have multiple installs of python, I do on my machine. However, if you install via an msi of a version of python 2.2 or above, I believe it creates a registry key like so:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Python.exe
which gives this value on my machine:
C:\Python25\Python.exe
You just read the registry key to get the location.
However, you can install python via an xcopy like model that you can have in an arbitrary place, and you just have to know where it is installed.
Replace a hard coded version to + example:
implementation 'com.google.android.gms:play-services-base:+'
implementation 'com.google.android.gms:play-services-maps:+'

Sun's JVM needs contiguous memory. So the maximal amount of available memory is dictated by memory fragmentation. Especially driver's dlls tend to fragment the memory, when loading into some predefined base address. So your hardware and its drivers determine how much memory you can get.
Two sources for this with statements from Sun engineers: forum blog
Maybe another JVM? Have you tried Harmony? I think they planned to allow non-continuous memory.
There are 2 differences:
2 methods creating a user and granting some privileges to him
create user userName identified by password;
grant connect to userName;
and
grant connect to userName identified by password;
do exactly the same. It creates a user and grants him the connect role.
different outcome
resource is a role in oracle, which gives you the right to create objects (tables, procedures, some more but no views!). ALL PRIVILEGES grants a lot more of system privileges.
To grant a user all privileges run you first snippet or

There is no such font as “Calibri (Body)”. You probably saw this string in Microsoft Word font selection menu, but it’s not a font name (see e.g. the explanation Font: +body (in W07)).
So use just font-family: Calibri
or, better, font-family: Calibri, sans-serif
. (There is no adequate backup font for Calibri, but the odds are that when Calibri is not available, the browser’s default sans-serif font suits your design better than the browser’s default font, which is most often a serif font.)
If none of them are working then check this.. say if you have x and y arrays of data along respective axis. Then check in which cell(jupyter) you have initialized x and y to empty. This is because , maybe you are appending data to x and y without re-initializing them. So plot has old data too. So check that..

Third match in google for "C++ slicing" gives me this Wikipedia article http://en.wikipedia.org/wiki/Object_slicing and this (heated, but the first few posts define the problem) : http://bytes.com/forum/thread163565.html
So it's when you assign an object of a subclass to the super class. The superclass knows nothing of the additional information in the subclass, and hasn't got room to store it, so the additional information gets "sliced off".
If those links don't give enough info for a "good answer" please edit your question to let us know what more you're looking for.
Are you using unmanaged code? If you are not using unmanaged code, according to Microsoft, memory leaks in the traditional sense are not possible.
Memory used by an application may not be released however, so an application's memory allocation may grow throughout the life of the application.
From How to identify memory leaks in the common language runtime at Microsoft.com
A memory leak can occur in a .NET Framework application when you use unmanaged code as part of the application. This unmanaged code can leak memory, and the .NET Framework runtime cannot address that problem.
Additionally, a project may only appear to have a memory leak. This condition can occur if many large objects (such as DataTable objects) are declared and then added to a collection (such as a DataSet). The resources that these objects own may never be released, and the resources are left alive for the whole run of the program. This appears to be a leak, but actually it is just a symptom of the way that memory is being allocated in the program.
For dealing with this type of issue, you can implement IDisposable. If you want to see some of the strategies for dealing with memory management, I would suggest searching for IDisposable, XNA, memory management as game developers need to have more predictable garbage collection and so must force the GC to do its thing.
One common mistake is to not remove event handlers that subscribe to an object. An event handler subscription will prevent an object from being recycled. Also, take a look at the using statement which allows you to create a limited scope for a resource's lifetime.
Arrays.asList(factors)
returns a List<int[]>
, not a List<Integer>
. Since you're doing new ArrayList
instead of new ArrayList<Integer>
you don't get a compile error for that, but create an ArrayList<Object>
which contains an int[]
and you then implicitly cast that arraylist to ArrayList<Integer>
. Of course the first time you try to use one of those "Integers" you get an exception.

It is not possible yet to search for content using multiple tags, for now only single tags are supported.
Firstly, the Instagram API endpoint "tags" required OAuth authentication.
This is not quite true, you only need an API-Key. Just register an application and add it to your requests. Example:
https://api.instagram.com/v1/users/userIdYouWantToGetMediaFrom/media/recent?client_id=yourAPIKey
Also note that the username is not the user-id. You can look up user-Id`s here.
A workaround for searching multiple keywords would be if you start one request for each tag and compare the results on your server. Of course this could slow down your site depending on how much keywords you want to compare.
You need to use v-bind:

What about signing your code with standard encryption schemes by hashing and signing important files and checking it with public key methods?
In this way you can issue license file with a public key for each customer.
Additional you can use an python obfuscator like this one (just googled it).

Using VBA.DateSerial(year,month,day)
you can overcome Excel's intrinsic bias to US date format. It also means you have full control over the data, which is something I personally prefer:
function convDate(str as string) as Date
Dim day, month, year as integer
year = int(mid(str,1,4))
month = int(mid(str,6,2))
day = int(mid(str,9,2))
convDate = VBA.DateSerial(year,month,day)

JNZ Jump if Not Zero ZF=0
Indeed, this is confusing right.
To make it easier to understand, replace Not Zero with Not Set. (Please take note this is for your own understanding)
Hence,
JNZ Jump if Not Set ZF=0
Not Set means flag Z = 0. So Jump (Jump if Not Set)
Set means flag Z = 1. So, do NOT Jump

In a function that has no side-effects, there's no good reason to have more than a single return and you should write them in a functional style. In a method with side-effects, things are more sequential (time-indexed), so you write in an imperative style, using the return statement as a command to stop executing.
In other words, when possible, favor this style
return a > 0 ?
positively(a):
negatively(a);
over this
if (a > 0)
return positively(a);
else
return negatively(a);
If you find yourself writing several layers of nested conditions, there's probably a way you can refactor that, using predicate list for example. If you find that your ifs and elses are far apart syntactically, you might want to break that down into smaller functions. A conditional block that spans more than a screenful of text is hard to read.
There's no hard and fast rule that applies to every language. Something like having a single return statement won't make your code good. But good code will tend to allow you to write your functions that way.

According to Fixture finalization / executing teardown code, the current best practice for setup and teardown is to use yield
instead of return
:
import pytest
@pytest.fixture()
def resource():
print("setup")
yield "resource"
print("teardown")
class TestResource:
def test_that_depends_on_resource(self, resource):
print("testing {}".format(resource))
Running it results in
$ py.test --capture=no pytest_yield.py
=== test session starts ===
platform darwin -- Python 2.7.10, pytest-3.0.2, py-1.4.31, pluggy-0.3.1
collected 1 items
pytest_yield.py setup
testing resource
.teardown
=== 1 passed in 0.01 seconds ===
Another way to write teardown code is by accepting a request
-context object into your fixture function and calling its request.addfinalizer
method with a function that performs the teardown one or multiple times:
import pytest
@pytest.fixture()
def resource(request):
print("setup")
def teardown():
print("teardown")
request.addfinalizer(teardown)
return "resource"
class TestResource:
def test_that_depends_on_resource(self, resource):
print("testing {}".format(resource))

break||(
code that cannot contain non paired closing bracket
)
While the goto
solution is a good option it will not work within brackets (including FOR and IF commands).But this will. Though you should be careful about closing brackets and invalid syntax for FOR
and IF
commands because they will be parsed.
Update
The update in the dbenham's answer gave me some ideas.
First - there are two different cases where we can need multi line comments - in a bracket's context where GOTO cannot be used and outside it.
Inside brackets context we can use another brackets if there's a condition which prevents the code to be executed.Though the code thede will still be parsed
and some syntax errors will be detected (FOR
,IF
,improperly closed brackets, wrong parameter expansion ..).So if it is possible it's better to use GOTO.
Though it is not possible to create a macro/variable used as a label - but is possible to use macros for bracket's comments.Still two tricks can be used make the GOTO
comments more symetrical and more pleasing (at least for me). For this I'll use two tricks - 1) you can put a single symbol in front of a label and goto will still able
to find it (I have no idea why is this.My guues it is searching for a drive). 2) you can put a single :
at the end of a variable name and a replacement/subtring feature will be not triggered (even under enabled extensions). Wich combined with the macros for brackets comments can
make the both cases to look almost the same.
So here are the examples (in the order I like them most):
With rectangular brackets:
@echo off
::GOTO comment macro
set "[:=goto :]%%"
::brackets comment macros
set "[=rem/||(" & set "]=)"
::testing
echo not commented 1
%[:%
multi
line
comment outside of brackets
%:]%
echo not commented 2
%[:%
second multi
line
comment outside of brackets
%:]%
::GOTO macro cannot be used inside for
for %%a in (first second) do (
echo first not commented line of the %%a execution
%[%
multi line
comment
%]%
echo second not commented line of the %%a execution
)
With curly brackets:
@echo off
::GOTO comment macro
set "{:=goto :}%%"
::brackets comment macros
set "{=rem/||(" & set "}=)"
::testing
echo not commented 1
%{:%
multi
line
comment outside of brackets
%:}%
echo not commented 2
%{:%
second multi
line
comment outside of brackets
%:}%
::GOTO macro cannot be used inside for loop
for %%a in (first second) do (
echo first not commented line of the %%a execution
%{%
multi line
comment
%}%
echo second not commented line of the %%a execution
)
With parentheses:
@echo off
::GOTO comment macro
set "(:=goto :)%%"
::brackets comment macros
set "(=rem/||(" & set ")=)"
::testing
echo not commented 1
%(:%
multi
line
comment outside of brackets
%:)%
echo not commented 2
%(:%
second multi
line
comment outside of brackets
%:)%
::GOTO macro cannot be used inside for loop
for %%a in (first second) do (
echo first not commented line of the %%a execution
%(%
multi line
comment
%)%
echo second not commented line of the %%a execution
)
Mixture between powershell and C styles (<
cannot be used because the redirection is with higher prio.*
cannot be used because of the %*
) :
@echo off
::GOTO comment macro
set "/#:=goto :#/%%"
::brackets comment macros
set "/#=rem/||(" & set "#/=)"
::testing
echo not commented 1
%/#:%
multi
line
comment outside of brackets
%:#/%
echo not commented 2
%/#:%
second multi
line
comment outside of brackets
%:#/%
::GOTO macro cannot be used inside for loop
for %%a in (first second) do (
echo first not commented line of the %%a execution
%/#%
multi line
comment
%#/%
echo second not commented line of the %%a execution
)
To emphase that's a comment (thought it is not so short):
@echo off
::GOTO comment macro
set "REM{:=goto :}REM%%"
::brackets comment macros
set "REM{=rem/||(" & set "}REM=)"
::testing
echo not commented 1
%REM{:%
multi
line
comment outside of brackets
%:}REM%
echo not commented 2
%REM{:%
second multi
line
comment outside of brackets
%:}REM%
::GOTO macro cannot be used inside for
for %%a in (first second) do (
echo first not commented line of the %%a execution
%REM{%
multi line
comment
%}REM%
echo second not commented line of the %%a execution
)
Note that URI encoding is good for the query part, it's not good for the domain. The domain gets encoded using punycode. You need a library like URI.js to convert between a URI and IRI (Internationalized Resource Identifier).
This is correct if you plan on using the string later as a query string:
> encodeURIComponent("http://examplé.org/rosé?rosé=rosé")
'http%3A%2F%2Fexampl%C3%A9.org%2Fros%C3%A9%3Fros%C3%A9%3Dros%C3%A9'
If you don't want ASCII characters like /
, :
and ?
to be escaped, use encodeURI
instead:
> encodeURI("http://examplé.org/rosé?rosé=rosé")
'http://exampl%C3%A9.org/ros%C3%A9?ros%C3%A9=ros%C3%A9'
However, for other use-cases, you might need uri-js instead:
> var URI = require("uri-js");
undefined
> URI.serialize(URI.parse("http://examplé.org/rosé?rosé=rosé"))
'http://xn--exampl-gva.org/ros%C3%A9?ros%C3%A9=ros%C3%A9'
One property of this approach that has not been pointed out so far is that because you create inner classes, the whole containing class is captured in its scope. This means that as long as your Set is alive, it will retain a pointer to the containing instance (this$0
) and keep that from being garbage-collected, which could be an issue.
This, and the fact that a new class gets created in the first place even though a regular HashSet would work just fine (or even better), makes me not want to use this construct (even though I really long for the syntactic sugar).
Second question: The new HashSet must be the "this" used in the instance initializer ... can anyone shed light on the mechanism? I'd have naively expected "this" to refer to the object initializing "flavors".
This is just how inner classes work. They get their own this
, but they also have pointers to the parent instance, so that you can call methods on the containing object as well. In case of a naming conflict, the inner class (in your case HashSet) takes precedence, but you can prefix "this" with a classname to get the outer method as well.
public class Test {
public void add(Object o) {
}
public Set<String> makeSet() {
return new HashSet<String>() {
{
add("hello"); // HashSet
Test.this.add("hello"); // outer instance
}
};
}
}
To be clear on the anonymous subclass being created, you could define methods in there as well. For example override HashSet.add()
public Set<String> makeSet() {
return new HashSet<String>() {
{
add("hello"); // not HashSet anymore ...
}
@Override
boolean add(String s){
}
};
}
Simple and easy:
$this->db->order_by("name", "asc");
$query = $this->db->get($this->table_name);
return $query->result();
As an extension to Ignacio Vazquez-Abrams' answer
>>> u'a?ä'.encode('ascii', 'ignore')
'a'
It is sometimes desirable to remove accents from characters and print the base form. This can be accomplished with
>>> import unicodedata
>>> unicodedata.normalize('NFKD', u'a?ä').encode('ascii', 'ignore')
'aa'
You may also want to translate other characters (such as punctuation) to their nearest equivalents, for instance the RIGHT SINGLE QUOTATION MARK unicode character does not get converted to an ascii APOSTROPHE when encoding.
>>> print u'\u2019'
’
>>> unicodedata.name(u'\u2019')
'RIGHT SINGLE QUOTATION MARK'
>>> u'\u2019'.encode('ascii', 'ignore')
''
# Note we get an empty string back
>>> u'\u2019'.replace(u'\u2019', u'\'').encode('ascii', 'ignore')
"'"
Although there are more efficient ways to accomplish this. See this question for more details Where is Python's "best ASCII for this Unicode" database?
<script src="test.js?random=<?php echo uniqid(); ?>"></script>
EDIT: Or you could use the file modification time so that it's cached on the client.
<script src="test.js?random=<?php echo filemtime('test.js'); ?>"></script>
getResource is fine, but using relative paths will work just as well too, as long as you can control where your working directory is (which you usually can).
Furthermore the platform dependence regarding the separator character can be gotten around using File.separator, File.separatorChar, or System.getProperty("file.separator").
Best I got so far:
dynamic DynamicCast(object entity, Type to)
{
var openCast = this.GetType().GetMethod("Cast", BindingFlags.Static | BindingFlags.NonPublic);
var closeCast = openCast.MakeGenericMethod(to);
return closeCast.Invoke(entity, new[] { entity });
}
static T Cast<T>(object entity) where T : class
{
return entity as T;
}
Swift 3
let phoneNumber: String = "tel://3124235234"
UIApplication.shared.openURL(URL(string: phoneNumber)!)
Worth mentioning that when using kotlin builtines (e.g. intArrayOf()
, longArrayOf()
, arrayOf()
, etc) you are not able to initialize the array with default values (or all values to desired value) for a given size, instead you need to do initialize via calling according to class constructor.
// Array of integers of a size of N
val arr = IntArray(N)
// Array of integers of a size of N initialized with a default value of 2
val arr = IntArray(N) { i -> 2 }
The script is performed before the DOM of the body is built. Put it all into a function and call it from the onload

LEFT JOIN (SELECT ip_location.ip, ip_location.hostname
FROM ip_location
WHERE ip_location.ip is null)tbl2
the answers above were confusing to me. Here is what i did:
the first field "Asset type" must be launcher icons. browse to the file you want as icon, select it and android studio will show you in the same window what it will look like under different resolutions.
choose a different name for it, click next. Now the icon set for all those hdpi, xhdpi, mdpi will be in corresponding mipmap folders
finally, most importantly go to your manifest file and change "android:icon" to the name of your new icon image.
The question as answered by Daniel is perfctly fine. I wanted to leave a note regarding NULLS. We should be carefull about using NOT IN operator when a column contains NULL values. You won't get any output if your column contains NULL values and you are using the NOT IN operator. This is how it's explained over here http://www.oraclebin.com/2013/01/beware-of-nulls.html , a very good article which I came across and thought of sharing it.
To extend the previous answer even more, like Ankit was saying, for complex objects you need to implement Serializable. For example, for the simple object:
public class MyClass implements Serializable {
private static final long serialVersionUID = -2163051469151804394L;
private int id;
private String created;
}
In you FromFragment:
Bundle args = new Bundle();
args.putSerializable(TAG_MY_CLASS, myClass);
Fragment toFragment = new ToFragment();
toFragment.setArguments(args);
getFragmentManager()
.beginTransaction()
.replace(R.id.body, toFragment, TAG_TO_FRAGMENT)
.addToBackStack(TAG_TO_FRAGMENT).commit();
in your ToFragment:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Bundle args = getArguments();
MyClass myClass = (MyClass) args
.getSerializable(TAG_MY_CLASS);
html
<input id="something" onkeyup="key_up(this)" type="text">

function key_up(e){
var enterKey = 13; //Key Code for Enter Key
if (e.which == enterKey){

}
}
Next time, Please try providing some code.

Inherits from a base test class (this example is testng

, but the ActiveProfiles

@ContextConfiguration(locations = { "classpath:spring-test-config.xml" })
@ActiveProfiles(resolver = MyActiveProfileResolver.class)
public class BaseTest extends AbstractTestNGSpringContextTests { }
MyActiveProfileResolver
can contain any logic required to determine which profile to use:
public class MyActiveProfileResolver implements ActiveProfilesResolver {
@Override
public String[] resolve(Class<?> aClass) {
// This can contain any custom logic to determine which profiles to use
return new String[] { "exampleProfile" };
}
}
This sets the profile which is then used to resolve dependencies required by the test.

Doing a chmod 777
is a fairly radical solution. Try these first, one at a time, and stop when one works:
$ sudo chmod -R 777 /usr/local/lib/node_modules/npm
$ sudo chmod -R 777 /usr/local/lib/node_modules
$ sudo chmod g+w /usr/local/lib
$ sudo chmod g+rwx /usr/local/lib
$ brew postinstall node
is the only install part where I would get a problem
Permission denied - /usr/local/lib/node_modules/npm/.github
So I
// !! READ EDIT ABOVE BEFORE RUNNING THIS CODE !!
$ sudo chmod -R 777 /usr/local/lib
$ brew postinstall node
and viola, npm is now linked
$ npm -v
3.10.10
Extra
If you used -R 777
on lib my recommendation would be to set nested files and directories to a default setting:
find /usr/local/lib -type f -print -exec chmod 644 {} \;
find /usr/local/lib -type d -print -exec chmod 755 {} \;
chmod /usr/local/lib 755
This is what I do, just add \n
and use encodeURIComponent
Example
var emailBody = "1st line.\n 2nd line \n 3rd line";
emailBody = encodeURIComponent(emailBody);
href = "mailto:[email protected]?body=" + emailBody;
Check encodeURIComponent docs

Another way is to use the subplots
function and pass the width ratio with gridspec_kw
:
import numpy as np
import matplotlib.pyplot as plt
# generate some data
x = np.arange(0, 10, 0.2)
y = np.sin(x)
# plot it
f, (a0, a1) = plt.subplots(1, 2, gridspec_kw={'width_ratios': [3, 1]})
a0.plot(x, y)
a1.plot(y, x)
f.tight_layout()
f.savefig('grid_figure.pdf')
Add reference .dll file to project. Right, Click on Project reference folder --> click on Add Reference -->.Net tab you will find System.Drawing --> click on ok this will add a reference to System.Drawing
Just a quick note for completing other more detailed answer (in term of code):
If I consider the question how-do-i-create-a-hash-table-in-java and especially the jGuru FAQ entry, I believe some other criteria upon which a hash code could be judged are:
install pip: https://pip.pypa.io/en/latest/installing.html
insatll boto: https://github.com/boto/boto
$ git clone git://github.com/boto/boto.git
$ cd boto
$ python setup.py install
Adding to sagiv's answer, we should create the parent component in such a way that it can consist all children components rather than returning the child components in the way you were trying to return.
Try to intentiate the parent component and pass the props inside it so that all children can use it like below
const NewComponent = NewHOC(Movie);
Here NewHOC is the parent component and all its child are going to use movie as props.
But any way, you guyd6 have solved a problem for new react developers as this might be a problem that can come too and here is where they can find the solution for that.
Here is an alternate syntax I use:
INSERT INTO tab_student
SET name_student = 'Bobby Tables',
id_teacher_fk = (
SELECT id_teacher
FROM tab_teacher
WHERE name_teacher = 'Dr. Smith')
I'm doing this in Excel to import a pivot table to a dimension table and a fact table in SQL so you can import to both department
and expenses
tables from the following:
Luckily, MySQL supports LAST_INSERT_ID()
exactly for this purpose.
INSERT INTO tab_teacher
SET name_teacher = 'Dr. Smith';
INSERT INTO tab_student
SET name_student = 'Bobby Tables',
id_teacher_fk = LAST_INSERT_ID()
Very annoying, no cookie file exmpale on the official website https://ec.haxx.se/http/http-cookies.
Finnaly, I find it does not work, if your file content is just copyied like this
foo1=bar;foo2=bar2
I gusess the format must looks the style said by @Agustí Sánchez . You can test it by -c to create a cookie file on a website.
So try this way, it works
curl -H "Cookie:`cat ./my.cookie`" http://xxxx.com
You can just copy the cookie from chrome console network tab.
Try following from Removing duplicates from an Array(simple):
Array.prototype.removeDuplicates = function (){
var temp=new Array();
this.sort();
for(i=0;i<this.length;i++){
if(this[i]==this[i+1]) {continue}
temp[temp.length]=this[i];
}
return temp;
}
Edit:
This code doesn't need sort:
Array.prototype.removeDuplicates = function (){
var temp=new Array();
label:for(i=0;i<this.length;i++){
for(var j=0; j<temp.length;j++ ){//check duplicates
if(temp[j]==this[i])//skip if already present
continue label;
}
temp[temp.length] = this[i];
}
return temp;
}
(But not a tested code!)

Garbage Collection in Java (and other languages/platforms as well) is a way for the java run-time environment (JRE) to reuse memory from java objects that are no longer needed. Simplistically, when the JRE initially starts up it asks the Operating System (O/S) for a certain amount of memory. As the JRE runs your application(s) it uses that memory. When your application is done using that memory, the JRE's "Garbage Collector" comes along and reclaims that memory for use by different parts of your existing application(s). The JRE's "Garbage Collector" is a background task that is always running and tries to pick times when the system is idle to go on its garbage runs.
A real world analogy would be the garbage men that come to your house and pick up your recyclable garbage... eventually, its reused in other ways by yourself and/or other people.
I haven't figured out yet why this occurs, but I had classes that were in my App_Code
folder that were calling methods in each other, and were fine in doing this when I built a .NET 4.5.2 project, but then I had to revert it to 4.0 as the target server wasn't getting upgraded. That's when I found this problem (after fixing the langversion
in my web.config from 6 to 5... another story)....
One of my methods kept having an error like:
The type X.Y conflicts with the imported type X.Y in MyProject.DLL
All of my classes were already set to "Compile" in their properties, as suggested on the accepted answer here, and each had a common namespace that was the same, and each had using MyNamespace;
at the top of each class.
I found that if I just moved the offending classes that had to call methods in each other to another, standard folder named something other than "App_Code", they stopped having this conflict issue.
Note: If you create a standard folder called "AppCode", move your classes into it, delete the "App_Code" folder, then rename "AppCode" to "App_Code", your problems will return. It doesn't matter if you use the "New Folder" or "Add ASP .NET Folder" option to create "App_Code" - it seems to key in on the name.
Maybe this is just a .NET 4.0 (and possibly earlier) issue... I was just fine in 4.5.2 before having to revert!
Your code is fine, but the problem is inside the batch file.
You have to show the content of the bat file, your problem is in the paths inside the bat file.
The root of it all is to make sure that the requests are coming from the actual users of the site. A csrf token is generated for the forms and Must be tied to the user's sessions. It is used to send requests to the server, in which the token validates them. This is one way of protecting against csrf, another would be checking the referrer header.
Chrome will make requests with CORS from a localhost
origin just fine. This isn't a problem with Chrome.
The reason you can't load http://stackoverflow.com
is that the Access-Control-Allow-Origin
headers weren't allowing your localhost
origin.
Try this
Get-ChildItem | % { Write-Host "$($_.FullName)\$buildConfig\$($_.Name).dll" }
In your code,
$build-Config
is not a valid variable name. $.FullName
should be $_.FullName
$
should be $_.Name
JavaScript is case sensitive.
So, if you want to change the font size, you have to go:
span.style.fontSize = "25px";
If you only care about the local machine, you can rely on the psutil package. You can either:
Check all ports used by a specific pid:
proc = psutil.Process(pid)
print proc.connections()
Check all ports used on the local machine:
print psutil.net_connections()
It works on Windows too.
You can do it like this:
postData[postData.length] = { name: "variable_name", value: variable_value };
I use:
Imports System.IO
Dim strPath as String=Directory.GetCurrentDirectory
Load image:
BufferedImage bufferedImage = ImageIO.read(file);
Resize it:
private BufferedImage resizeAndCrop(BufferedImage bufferedImage, Integer width, Integer height) {
Mode mode = (double) width / (double) height >= (double) bufferedImage.getWidth() / (double) bufferedImage.getHeight() ? Scalr.Mode.FIT_TO_WIDTH
: Scalr.Mode.FIT_TO_HEIGHT;
bufferedImage = Scalr.resize(bufferedImage, Scalr.Method.ULTRA_QUALITY, mode, width, height);
int x = 0;
int y = 0;
if (mode == Scalr.Mode.FIT_TO_WIDTH) {
y = (bufferedImage.getHeight() - height) / 2;
} else if (mode == Scalr.Mode.FIT_TO_HEIGHT) {
x = (bufferedImage.getWidth() - width) / 2;
}
bufferedImage = Scalr.crop(bufferedImage, x, y, width, height);
return bufferedImage;
}
Using Scalr library:
<dependency>
<groupId>org.imgscalr</groupId>
<artifactId>imgscalr-lib</artifactId>
<version>4.2</version>
</dependency>
If it's because each tab will be running a different flow in your application, and mixing both flows causes problems, then it's better to "Regionalize" your session objects, so that each flow will use a different region of the session
This region can be implemented as simply as having different prefixes for each flow, or session object will hold multiple maps (one for each flow), and you use those maps instead of session attributes, the best though would be to extend your session class and use it instead.
You could use Series.reindex
:
import pandas as pd
idx = pd.date_range('09-01-2013', '09-30-2013')
s = pd.Series({'09-02-2013': 2,
'09-03-2013': 10,
'09-06-2013': 5,
'09-07-2013': 1})
s.index = pd.DatetimeIndex(s.index)
s = s.reindex(idx, fill_value=0)
print(s)
yields
2013-09-01 0
2013-09-02 2
2013-09-03 10
2013-09-04 0

Facebook has new requirements change: an access token will be required for all UID-based queries
So you have to add your app access token to the url:
https://graph.facebook.com/{profile_id}/picture?type=large&access_token={app_access_token}
To get your app_access_token
use the following url:
https://graph.facebook.com/oauth/access_token?client_id={your-app-id}&client_secret={your-app-secret}&grant_type=client_credentials
You find your-app-id
and your-app-secret
in the Basic Settings of your Facebook app in Facebook developers
You could wrap your return value in the Boolean function
Boolean([return value])
That'll ensure all falsey values are false and truthy statements are true.
I created a working CodePen example demonstrating how to do this the correct way in AngularJS. The Angular $window service should be used to access any global objects since directly accessing window
makes testing more difficult.
HTML:
<section ng-app="myapp" ng-controller="MainCtrl">
Value of global variable read by AngularJS: {{variable1}}
</section>
JavaScript:
// global variable outside angular
var variable1 = true;
var app = angular.module('myapp', []);
app.controller('MainCtrl', ['$scope', '$window', function($scope, $window) {
$scope.variable1 = $window.variable1;
}]);

I realize the question might be rather old, but you say the backend is running on the same server. That means on a different port, probably other than the default port 80.
I've read that when you use the "connectionManagement" configuration element, you need to specify the port number if it differs from the default 80.
LINK: maxConnection setting may not work even autoConfig = false in ASP.NET
Secondly, if you choose to use the default configuration (address="*") extended with your own backend specific value, you might consider putting the specific value first! Otherwise, if a request is made, the * matches first and the default of 2 connections is taken. Just like when you use the section in web.config.
LINK: <remove> Element for connectionManagement (Network Settings)

For many S3 API packages (I recently had this problem the npm s3 package) you can run into issues where the region is assumed to be US Standard, and lookup by name will require you to explicitly define the region if you choose to host a bucket outside of that region.
Many people will suggest you use MERGE
, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:
http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/
Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;
A lot of folks will suggest this way:
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
UPDATE ...
END
ELSE
BEGIN
INSERT ...
END
COMMIT TRANSACTION;
But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)
Others will suggest this way:
BEGIN TRY
INSERT ...
END TRY
BEGIN CATCH
IF ERROR_NUMBER() = 2627
UPDATE ...
END CATCH
However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:
Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE
is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.
I had the same problem but it occured in all my projects, I tried Invalidate Cache / Restart
but even it doesn´t solved the problem.
At the end I realized that in my Gradle Settings
, Offline Work
was enabled.

in Gradle Settings
unchecked Offline Work

It solved the the problem downloading some configuration files for my Android Studio.
What Anthony says is absolutely correct, but I'd like to add that your experience will likely show a lot better performance and efficiency (due not to fpm
-vs-fcgi
but more to the implementation of your httpd
).
For example, I had a quad-core machine running lighttpd
+ fcgi
humming along nicely. I upgraded to a 16-core machine to cope with growth, and two things exploded: RAM usage, and segfaults. I found myself restarting lighttpd
every 30 minutes to keep the website up.
I switched to php-fpm and nginx, and RAM usage dropped from >20GB to 2GB. Segfaults disappeared as well. After doing some research, I learned that lighttpd and fcgi don't get along well on multi-core machines under load, and also have memory leak issues in certain instances.
Is this due to php-fpm
being better than fcgi
? Not entirely, but how you hook into php-fpm
seems to be a whole heckuva lot more efficient than how you serve via fcgi
.
As mentioned elsewhere, the CSS function calc() can work nicely here. It is now mostly supported. You could use like:
.container
{
min-height: 70%;
min-height: -webkit-calc(100% - 300px);
min-height: -moz-calc(100% - 300px);
min-height: calc(100% - 300px);
}
&&
lets you do something based on whether the previous command completed successfully - that's why you tend to see it chained as do_something && do_something_else_that_depended_on_something
.
Just in case for data.table
users, the following works for me:
df[, grep("ABC", names(df)), with = FALSE]
I realize this is a very old post, but I have had success using the JUCE library, which builds projects for the major IDE's like Xcode, VS, and Codeblocks and automatically builds VST/3, AU/v3, RTAS, and AAX.
interestingly in my git-bash on windows sed ""
did the trick already:
$ echo -e "abc\r" >tst.txt
$ file tst.txt
tst.txt: ASCII text, with CRLF line terminators
$ sed -i "" tst.txt
$ file tst.txt
tst.txt: ASCII text
My guess is that sed ignores them when reading lines from input and always writes unix line endings on output.
This macro adds a hyperlink to the worksheet with the same name, I also modify the range to be more flexible, just change the first cell in the code. Works like a charm
Sub hyper()
Dim cl As Range
Dim nS As String
Set MyRange = Sheets("Sheet1").Range("B16")
Set MyRange = Range(MyRange, MyRange.End(xlDown))
For Each cl In MyRange
nS = cl.Value
cl.Hyperlinks.Add Anchor:=cl, Address:="", SubAddress:="'" & nS & "'" & "!B16", TextToDisplay:=nS
Next
End Sub

I think Rubens' class is a good idea so thought to make an immutable sample of his Time class with basic validation.
class Time
{
public int Hours { get; private set; }
public int Minutes { get; private set; }
public int Seconds { get; private set; }
public Time(uint h, uint m, uint s)
{
if(h > 23 || m > 59 || s > 59)
{
throw new ArgumentException("Invalid time specified");
}
Hours = (int)h; Minutes = (int)m; Seconds = (int)s;
}
public Time(DateTime dt)
{
Hours = dt.Hour;
Minutes = dt.Minute;
Seconds = dt.Second;
}
public override string ToString()
{
return String.Format(
"{0:00}:{1:00}:{2:00}",
this.Hours, this.Minutes, this.Seconds);
}
}
This can be changed in your my.ini
file (on Windows, located in \Program Files\MySQL\MySQL Server) under the server section, for example:
[mysqld]
max_allowed_packet = 10M
Step 1:
cd /etc/postgresql/12/main/
open file named postgresql.conf
sudo nano postgresql.conf
add this line to that file
listen_addresses = '*'
then open file named pg_hba.conf
sudo nano pg_hba.conf
and add this line to that file
host all all 0.0.0.0/0 md5
It allows access to all databases for all users with an encrypted password
restart your server
sudo /etc/init.d/postgresql restart
I used the Bootstrap 4 buttons plugin (https://getbootstrap.com/docs/4.0/components/buttons/#button-plugin) and added the class rounded to the labels and the class mx-1 to the middle button to achieve the desired look and feel of separate radio buttons. Using the class btn-toolbar made the radio button circles appear for me which is not what I wanted. Hope this helps someone.
<div class="btn-group btn-group-toggle" data-toggle="buttons">
<label class="btn btn-secondary active rounded">
<input type="radio" name="options" id="option1" autocomplete="off" checked> Active

<label class="btn btn-secondary rounded mx-1">
<input type="radio" name="options" id="option2" autocomplete="off"> Radio
</label>
<label class="btn btn-secondary rounded">
<input type="radio" name="options" id="option3" autocomplete="off"> Radio
