POD is the official way to do multi line comments in Perl,
From faq.perl.org[perlfaq7]
The quick-and-dirty way to comment out more than one line of Perl is to surround those lines with Pod directives. You have to put these directives at the beginning of the line and somewhere where Perl expects a new statement (so not in the middle of statements like the # comments). You end the comment with
=cut
, ending the Pod section:
=pod
my $object = NotGonnaHappen->new();
ignored_sub();
$wont_be_assigned = 37;
=cut
The quick-and-dirty method only works well when you don't plan to leave the commented code in the source. If a Pod parser comes along, your multiline comment is going to show up in the Pod translation. A better way hides it from Pod parsers as well.
The
=begin
directive can mark a section for a particular purpose. If the Pod parser doesn't want to handle it, it just ignores it. Label the comments withcomment
. End the comment using=end
with the same label. You still need the=cut
to go back to Perl code from the Pod comment:
=begin comment
my $object = NotGonnaHappen->new();
ignored_sub();
$wont_be_assigned = 37;
=end comment
=cut
I discovered SqlBulkCopy is an easy way to do this, and does not require a stored procedure to be written in SQL Server.
Here is an example of how I implemented it:
// take note of SqlBulkCopyOptions.KeepIdentity , you may or may not want to use this for your situation.
using (var bulkCopy = new SqlBulkCopy(_connection.ConnectionString, SqlBulkCopyOptions.KeepIdentity))
{
// my DataTable column names match my SQL Column names, so I simply made this loop. However if your column names don't match, just pass in which datatable name matches the SQL column name in Column Mappings
foreach (DataColumn col in table.Columns)
{
bulkCopy.ColumnMappings.Add(col.ColumnName, col.ColumnName);
}
bulkCopy.BulkCopyTimeout = 600;
bulkCopy.DestinationTableName = destinationTableName;
bulkCopy.WriteToServer(table);
}
1. Chrome
For debugging AngularJS in Chrome you can use AngularJS Batarang. (From recent reviews on the plugin it seems like AngularJS Batarang is no longer being maintained. Tested in various versions of Chrome and it does not work.)
Here is the the link for a description and demo: Introduction of Angular JS Batarang
Download Chrome plugin from here: Chrome plugin for debugging AngularJS
You can also use ng-inspect for debugging angular.
2. Firefox
For Firefox with the help of Firebug you can debug the code.
Also use this Firefox Add-Ons: AngScope: Add-ons for Firefox (Not official extension by AngularJS Team)

"This is a comment in vimrc. It does not have a closing quote

This error is coming from the staticfile handler -- which by default doesn't filter any verbs, but probably can only deal with HEAD and GET.
And this is because no other handler stepped up to the plate and said they could handle DELETE.
Since you are using the WEBAPI, which because of routing doesn't have files and therefore extensions, the following additions need to be added to your web.config file:
<system.webserver>
<httpProtocol>
<handlers>
...
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="C:\windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="C:\windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
Obviously what is needed depends on classicmode vs integratedmode, and classicmode depends on bitness. In addition, the OPTIONS header has been added for CORS processing, but if you don't do CORS you don't need that.
FYI, your web.config is the local to the application (or application directory) version whose top level is applicationHost.config.
JavaScript/jQuery
$("#entersomething").keyup(function(e){
var code = e.key; // recommended to use e.key, it's normalized across devices and languages
if(code==="Enter") e.preventDefault();
if(code===" " || code==="Enter" || code===","|| code===";"){

For me the solution was easy, there was no room left on drive C, once deleted some old files i was able to perform IISReset and all the services started successfully.
Try using in
like this:
>>> x = 'hello'
>>> y = 'll'
>>> y in x
True
Try this Code
List itemStates = new List();
for (int i = 0; i < 10; i++)
{
itemStates.Add(new ItemState { Id = i.ToString() });
dataGridView1.DataSource = itemStates;
dataGridView1.DataBind();
System.Threading.Thread.Sleep(500);
}
Please note that inserted, deleted
means the same thing as inserted CROSS JOIN deleted
and gives every combination of every row. I doubt this is what you want.
Something like this may help get you started...
SELECT
CASE WHEN inserted.primaryKey IS NULL THEN 'This is a delete'
WHEN deleted.primaryKey IS NULL THEN 'This is an insert'
ELSE 'This is an update'
END as Action,
*
FROM
inserted
FULL OUTER JOIN
deleted
ON inserted.primaryKey = deleted.primaryKey
Depending on what you want to do, you then reference the table you are interested in with inserted.userID
or deleted.userID
, etc.
Finally, be aware that inserted
and deleted
are tables and can (and do) contain more than one record.
If you insert 10 records at once, the inserted
table will contain ALL 10 records. The same applies to deletes and the deleted
table. And both tables in the case of an update.
EDIT Examplee Trigger after OPs edit.
ALTER TRIGGER [dbo].[UpdateUserCreditsLeft]
ON [dbo].[Order]
AFTER INSERT,UPDATE,DELETE
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from

SET NOCOUNT ON;

SET
CreditsLeft = CASE WHEN inserted.UserID IS NULL THEN <new value for a DELETE>
WHEN deleted.UserID IS NULL THEN <new value for an INSERT>

(
inserted
FULL OUTER JOIN
deleted
ON inserted.UserID = deleted.UserID -- This assumes UserID is the PK on UpdateUserCreditsLeft
)
ON User.UserID = COALESCE(inserted.UserID, deleted.UserID)

If the PrimaryKey of UpdateUserCreditsLeft
is something other than UserID, use that in the FULL OUTER JOIN instead.
You can simply subclass UIButton and write your own drawing code to suit your needs. I implemented a radio button like that of android using the following code. It can be used in storyboard as well.See example in Github repo
import UIKit
@IBDesignable
class SPRadioButton: UIButton {
@IBInspectable
var gap:CGFloat = 8 {
didSet {
self.setNeedsDisplay()
}
}
@IBInspectable
var btnColor: UIColor = UIColor.green{
didSet{
self.setNeedsDisplay()
}
}
@IBInspectable
var isOn: Bool = true{
didSet{
self.setNeedsDisplay()
}
}
override func draw(_ rect: CGRect) {
self.contentMode = .scaleAspectFill
drawCircles(rect: rect)
}
//MARK:- Draw inner and outer circles
func drawCircles(rect: CGRect){
var path = UIBezierPath()
path = UIBezierPath(ovalIn: CGRect(x: 0, y: 0, width: rect.width, height: rect.height))
let circleLayer = CAShapeLayer()
circleLayer.path = path.cgPath
circleLayer.lineWidth = 3
circleLayer.strokeColor = btnColor.cgColor
circleLayer.fillColor = UIColor.white.cgColor
layer.addSublayer(circleLayer)
if isOn {
let innerCircleLayer = CAShapeLayer()
let rectForInnerCircle = CGRect(x: gap, y: gap, width: rect.width - 2 * gap, height: rect.height - 2 * gap)
innerCircleLayer.path = UIBezierPath(ovalIn: rectForInnerCircle).cgPath
innerCircleLayer.fillColor = btnColor.cgColor
layer.addSublayer(innerCircleLayer)
}
self.layer.shouldRasterize = true
self.layer.rasterizationScale = UIScreen.main.nativeScale
}
/*
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
isOn = !isOn
self.setNeedsDisplay()
}
*/
override func awakeFromNib() {
super.awakeFromNib()
addTarget(self, action: #selector(buttonClicked(sender:)), for: UIControl.Event.touchUpInside)
isOn = false
}
@objc func buttonClicked(sender: UIButton) {
if sender == self {
isOn = !isOn
setNeedsDisplay()
}
}
}
You need to enclose that in <%! %> as follows:
<%!
public String getQuarter(int i){
String quarter;
switch(i){
case 1: quarter = "Winter";
break;
case 2: quarter = "Spring";
break;
case 3: quarter = "Summer I";
break;
case 4: quarter = "Summer II";
break;
case 5: quarter = "Fall";
break;
default: quarter = "ERROR";
}
return quarter;
}
%>
You can then invoke the function within scriptlets or expressions:
<%
out.print(getQuarter(4));
%>
or
<%= getQuarter(17) %>
If you're using CI 2.0 or newer, you could change ENVIRONMENT
type in your index.php
to define('ENVIRONMENT', 'testing');
.
Alternatively, you could add php_flag display_errors on
to your .htaccess
file.
The answer given by P????? creates a nullable bool, not a bool, which may be fine for you. For example in C# it would create: bool? AdminApproved
not bool AdminApproved
.
If you need to create a bool (defaulting to false):
ALTER TABLE person
ADD AdminApproved BIT
DEFAULT 0 NOT NULL;
You can use LENGTH() for CHAR / VARCHAR2 and DBMS_LOB.GETLENGTH() for CLOB. Both functions will count actual characters (not bytes).
See the linked documentation if you do need bytes.
Use NuGet (VS 2013+):
The easiest way in any recent version of Visual Studio is to just use the NuGet package manager. (Even VS2013, with the NuGet Package Manager for Visual Studio 2013 extension.)
Right-click on "References" and choose "Manage NuGet Packages...", then just search for Excel.
VS 2012:
Older versions of VS didn't have access to NuGet.

.You cannot use js variables inside html. To add the content of the javascript variable to the html use innerHTML() or create any html tag, add the content of that variable to that created tag and append that tag to the body or any other existing tags in the html.
Yes, I think for Windows users you need to change all the python3
calls to python
to solve your original error. This change will run the Python version set in your current environment. If you need to keep this call as it is (aka python3
) because you are working in cross-platform or for any other reason, then a work around is to create a soft link. To create it, go to the folder that contains the Python executable and create the link. For example, this worked in my case in Windows 10 using mklink:
cd C:\Python3
mklink python3.exe python.exe
Use a (soft) symbolic link in Linux:
cd /usr/bin/python3
ln -s python.exe python3.exe
A cleaner alternative of putting your config file into a subfolder of src/main/resources would be to enhance your classpath locations. This is extremely easy to do with Maven.
For instance, place your property file in a new folder src/main/config, and add the following to your pom:
<build>
<resources>
<resource>
<directory>src/main/config</directory>
</resource>
</resources>
</build>
From now, every files files under src/main/config is considered as part of your classpath (note that you can exclude some of them from the final jar if needed: just add in the build section:
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<excludes>
<exclude>my-config.properties</exclude>
</excludes>
</configuration>
</plugin>
</plugins>
so that my-config.properties can be found in your classpath when you run your app from your IDE, but will remain external from your jar in your final distribution).
You can use one of the functions of jFunc - use the function "jFunc_CanvasFilterGrayscale" http://jfunc.com/jFunc-functions.aspx
Use for
, something along the lines of:
set content=
for /f "delims=" %%i in ('filename') do set content=%content% %%i
Maybe you’ll have to do setlocal enabledelayedexpansion
and/or use !content!
rather than %content%
. I can’t test, as I don’t have any MS Windows nearby (and I wish you the same :-).
The best batch-file-black-magic-reference I know of is at http://www.rsdn.ru/article/winshell/batanyca.xml. If you don’t know Russian, you still could make some use of the code snippets provided.
Update to MySQL 8.0.16 to use checks
:
As of MySQL 8.0.16, CREATE TABLE permits the core features of table and column CHECK constraints, for all storage engines. CREATE TABLE permits the following CHECK constraint syntax, for both table constraints and column constraints
For anyone who comes here, as I did, looking for the syntax to change origin to a different location you can find that documentation here: https://help.github.com/articles/changing-a-remote-s-url/. Using git remote add
to do this will result in "fatal: remote origin already exists."
Nutshell:
git remote set-url origin https://github.com/username/repo

I have one quick remedy for this. In fact I got this error because I had not set my web page as start page. When I did my web page(html /aspx) as set start page as shown below I got this error corrected.
I don't know whether this solution will help others.
Try this:
var src = DateTime.Now;
var hm = new DateTime(src.Year, src.Month, src.Day, src.Hour, src.Minute, 0);
Try changing the encoding.
In my case, encoding = "utf-16"
worked.
df = pd.read_csv("file.csv",encoding='utf-16')
This is my solution :
$(document).ready(function () {
$( "td" ).on({
"click": clicked,
"mouseover": hovered,
"mouseout": mouseout
});
var flag=0;
function hovered(){
$(this).css("background", "#380606");
}
function mouseout(){
if (flag == 0){
$(this).css("background", "#ffffff");
} else {
flag=0;
}
}
function clicked(){
$(this).css("background","#000000");
flag=1;
}
})
The answer, u
, (and many others) is in $ vimtutor
.
There are two ways to achieve this.
1- As already proposed u can set the background of your spinner as custom 9 patch Image with all the adjustments made into it .
android:background="@drawable/btn_dropdown"
android:clickable="true"
android:dropDownVerticalOffset="-10dip"
android:dropDownHorizontalOffset="0dip"
android:gravity="center"
If you want your Spinner to show With various different background colors i would recommend making the drop down image transparent, & loading that spinner in a relative layout with your color set in.
btn _dropdown is as:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_window_focused="false" android:state_enabled="true"
android:drawable="@drawable/spinner_default" />
<item
android:state_window_focused="false" android:state_enabled="false"
android:drawable="@drawable/spinner_default" />
<item
android:state_pressed="true"
android:drawable="@drawable/spinner_pressed" />
<item
android:state_focused="true" android:state_enabled="true"
android:drawable="@drawable/spinner_pressed" />
<item
android:state_enabled="true"
android:drawable="@drawable/spinner_default" />
<item
android:state_focused="true"
android:drawable="@drawable/spinner_pressed" />
<item
android:drawable="@drawable/spinner_default" />
</selector>
where the various states of pngwould define your various States of spinner seleti

If you need to pass UUID for a primary key for your model or unique field then below code returns the UUID object -
import uuid
uuid.uuid4()
If you need to pass UUID as a parameter for URL you can do like below code -
import uuid
str(uuid.uuid4())
If you want the hex value for a UUID you can do the below one -
import uuid
uuid.uuid4().hex
I am using this script after I rename my iOS Project. It helps to change the directories name and make the names in sync.

MySQL 5.5 on Ubuntu 14.04 required slightly different commands as recommended here. In a nutshell:
sudo /etc/init.d/mysql stop
sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &
mysql -u root
And then from the MySQL prompt
FLUSH PRIVILEGES;
SET PASSWORD FOR root@'localhost' = PASSWORD('password');
UPDATE mysql.user SET Password=PASSWORD('newpwd') WHERE User='root';
FLUSH PRIVILEGES;
And the cited source offers an alternate method as well.
It's a great question, but be warned that you're treading in dangerous waters here. When you're deleting code you will have to make sure you're compiling and testing often.
One great tool come to mind:
NDepend - this tool is just amazing. It takes a little while to grok, and after the first 10 minutes I think most developers just say "Screw it!" and delete the app. Once you get a good feel for NDepend, it gives you amazing insight to how your apps are coupled. Check it out: http://www.ndepend.com/. Most importantly, this tool will allow you to view methods which do not have any direct callers. It will also show you the inverse, a complete call tree for any method in the assembly (or even between assemblies).
Whatever tool you choose, it's not a task to take lightly. Especially if you're dealing with public methods on library type assemblies, as you may never know when an app is referencing them.
ResourceManager and .resx are bit messy.
You could use Lexical.Localization¹ which allows embedding default value and culture specific values into the code, and be expanded in external localization files for futher cultures (like .json or .resx).
public class MyClass
{
/// <summary>
/// Localization root for this class.
/// </summary>
static ILine localization = LineRoot.Global.Type<MyClass>();
/// <summary>
/// Localization key "Ok" with a default string, and couple of inlined strings for two cultures.
/// </summary>
static ILine ok = localization.Key("Success")
.Text("Success")
.fi("Onnistui")
.sv("Det funkar");
/// <summary>
/// Localization key "Error" with a default string, and couple of inlined ones for two cultures.
/// </summary>
static ILine error = localization.Key("Error")
.Format("Error (Code=0x{0:X8})")
.fi("Virhe (Koodi=0x{0:X8})")
.sv("Sönder (Kod=0x{0:X8})");
public void DoOk()
{
Console.WriteLine( ok );
}
public void DoError()
{
Console.WriteLine( error.Value(0x100) );
}
}

As for your problem, currently you will have to depend on XHR or websockets for this.
Currently no popular browser has implemented any such raw sockets api for javascript that lets you create and access raw sockets, but a draft for the implementation of raw sockets api in JavaScript is under-way. Have a look at these links:
http://www.w3.org/TR/raw-sockets/
https://developer.mozilla.org/en-US/docs/Web/API/TCPSocket
Chrome now has support for raw TCP and UDP sockets in its ‘experimental’ APIs. These features are only available for extensions and, although documented, are hidden for the moment. Having said that, some developers are already creating interesting projects using it, such as this IRC client.
To access this API, you’ll need to enable the experimental flag in your extension’s manifest. Using sockets is pretty straightforward, for example:
chrome.experimental.socket.create('tcp', '127.0.0.1', 8080, function(socketInfo) {
chrome.experimental.socket.connect(socketInfo.socketId, function (result) {
chrome.experimental.socket.write(socketInfo.socketId, "Hello, world!");
});
});
Well that is Because of
you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception. and the one way is to encrypt that data Directly into the String.
look this. Try and u will be able to resolve this
public static String decrypt(String encryptedData) throws Exception {
Key key = generateKey();
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.DECRYPT_MODE, key);
String decordedValue = new BASE64Decoder().decodeBuffer(encryptedData).toString().trim();
System.out.println("This is Data to be Decrypted" + decordedValue);
return decordedValue;
}
hope that will help.
database_password: password
would between quotes: " or '.
like so:
database_password: "password"
What about a wrapper around your existing code:
public Collection<File> getMatchingFiles( String directory, String extension ) {
return new ArrayList<File>()(
getAllFilesThatMatchFilenameExtension( directory, extension ) );
}
I will throw a warning though. If you can live with that warning, then you're done.
If you need to get the work done inside Pg:
to_json(value)
https://www.postgresql.org/docs/9.3/static/functions-json.html#FUNCTIONS-JSON-TABLE
This will end the function, and you can even customize the "Error" message:
import sys
def end():
if condition:
# the player wants to play again:
main()
elif not condition:
sys.exit("The player doesn't want to play again") #Right here
Oracle does not have a simple database model like MySQL or MS SQL Server. I find the closest thing is to query the tablespaces and the corresponding users within them.
For example, I have a DEV_DB tablespace with all my actual 'databases' within them:
SQL> SELECT TABLESPACE_NAME FROM USER_TABLESPACES;
Resulting in:
SYSTEM SYSAUX UNDOTBS1 TEMP USERS EXAMPLE DEV_DB
It is also possible to query the users in all tablespaces:
SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS;
Or within a specific tablespace (using my DEV_DB tablespace as an example):
SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS where DEFAULT_TABLESPACE = 'DEV_DB';
ROLES DEV_DB
DATAWARE DEV_DB
DATAMART DEV_DB
STAGING DEV_DB
I agree with Jim Blizard. The database is not the part of your technology stack that should send emails. For example, what if you send an email but then roll back the change that triggered that email? You can't take the email back.
It's better to send the email in your application code layer, after your app has confirmed that the SQL change was made successfully and committed.
For me, it worked once I changed
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
to:
in POM
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>6.1.0.jre8</version>
</dependency>
and then:
import com.microsoft.sqlserver.jdbc.SQLServerDriver;
...
DriverManager.registerDriver(SQLServerDriver());
Connection connection = DriverManager.getConnection(connectionUrl);
s = 'hi how are you'
l = list(map(lambda x: x,s.split()))
print(l)
Output: ['hi', 'how', 'are', 'you']
I needed to print important warning about skipped tests exactly when PyTest
muted literally everything.
I didn't want to fail a test to send a signal, so I did a hack as follow:
def test_2_YellAboutBrokenAndMutedTests():
import atexit
def report():
print C_patch.tidy_text("""
In silent mode PyTest breaks low level stream structure I work with, so
I cannot test if my functionality work fine. I skipped corresponding tests.
Run `py.test -s` to make sure everything is tested.""")
if sys.stdout != sys.__stdout__:
atexit.register(report)
The atexit
module allows me to print stuff after PyTest
released the output streams. The output looks as follow:
============================= test session starts ==============================
platform linux2 -- Python 2.7.3, pytest-2.9.2, py-1.4.31, pluggy-0.3.1

~/.../sources/C_patch$
Message is printed even when PyTest
is in silent mode, and is not printed if you run stuff with py.test -s
, so everything is tested nicely already.
To do it the GUI way, you need to go edit your login. One of its properties is the default database used for that login. You can find the list of logins under the Logins node under the Security node. Then select your login and right-click and pick Properties. Change the default database and your life will be better!
Note that someone with sysadmin privs needs to be able to login to do this or to run the query from the previous post.
Five years later, when I Google "how to create a kernel density plot using python", this thread still shows up at the top!
Today, a much easier way to do this is to use seaborn, a package that provides many convenient plotting functions and good style management.

appears to something once bundled with Borland and/or Turbo C++, in the 90's.
http://www.daniweb.com/software-development/cpp/threads/17709/88149#post88149
It's unlikely that you will find any support for that file with modern compiler. For other graphics libraries check the list of "related" questions (questions related to this one). E.g., "A Simple, 2d cross-platform graphics library for c or c++?".

hope it helps to someone.
Overloading is a part of static polymorphism and is used to implement different method with same name but different signatures. Overriding is used to complete the incomplete method. In my opinion there is no comparison between these two concepts, the only thing is similar is that both come with the same vocabulary that is over.
Since this thread is one of the top results for that error and has no fix yet, I'll post what I found to fix it, originally found in this thread: Build Failure? "Unable to start program... The system cannot find the file specificed" which lead me to this thread: Error 'LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt' after installing Visual Studio 2012 Release Preview
Basically all I did is this:
Project Properties
-> Configuration Properties
-> Linker (General)
-> Enable Incremental Linking -> "No (/INCREMENTAL:NO)"
Extension of the question answered here How do you tell if a string contains another string in POSIX sh?:
This solution works with special characters:
# contains(string, substring)
#
# Returns 0 if the specified string contains the specified substring,
# otherwise returns 1.
contains() {
string="$1"
substring="$2"
if echo "$string" | $(type -p ggrep grep | head -1) -F -- "$substring" >/dev/null; then
return 0 # $substring is in $string
else
return 1 # $substring is not in $string
fi
}
contains "abcd" "e" || echo "abcd does not contain e"
contains "abcd" "ab" && echo "abcd contains ab"
contains "abcd" "bc" && echo "abcd contains bc"
contains "abcd" "cd" && echo "abcd contains cd"
contains "abcd" "abcd" && echo "abcd contains abcd"
contains "" "" && echo "empty string contains empty string"
contains "a" "" && echo "a contains empty string"
contains "" "a" || echo "empty string does not contain a"
contains "abcd efgh" "cd ef" && echo "abcd efgh contains cd ef"
contains "abcd efgh" " " && echo "abcd efgh contains a space"
contains "abcd [efg] hij" "[efg]" && echo "abcd [efg] hij contains [efg]"
contains "abcd [efg] hij" "[effg]" || echo "abcd [efg] hij does not contain [effg]"
contains "abcd *efg* hij" "*efg*" && echo "abcd *efg* hij contains *efg*"
contains "abcd *efg* hij" "d *efg* h" && echo "abcd *efg* hij contains d *efg* h"
contains "abcd *efg* hij" "*effg*" || echo "abcd *efg* hij does not contain *effg*"
Thanks to earlier answers, this blocks serves well as a general purpose solution for applying a configurable string into a RegEx .. for filtering text:
var permittedChars = '^a-z0-9 _,.?!@+<>';
permittedChars = '[' + permittedChars + ']';
var flags = 'gi';
var strFilterRegEx = new RegExp(permittedChars, flags);
log.debug ('strFilterRegEx: ' + strFilterRegEx);
strVal = strVal.replace(strFilterRegEx, '');
// this replaces hard code solt:
// strVal = strVal.replace(/[^a-z0-9 _,.?!@+]/ig, '');
The differences I could see is that Robocopy has a lot more options, but I didn't find any of them particularly helpful unless I'm doing something special.
I did some benchmarking of several copy routines and found XCOPY and ROBOCOPY to be the fastest, but to my surprise, XCOPY consistently edged out Robocopy.
It's ironic that robocopy retries a copy that fails, but it also failed a lot in my benchmark tests, where xcopy never did.
I did full file (byte by byte) file compares after my benchmark tests.
Here are the switches I used with robocopy in my tests:
**"/E /R:1 /W:1 /NP /NFL /NDL"**.
If anyone knows a faster combination (other than removing /E, which I need), I'd love to hear.
Another interesting/disappointing thing with robocopy is that if a copy does fail, by default it retries 1,000,000 times with a 30 second delay between each try. If you are running a long batch file unattended, you may be very disappointed when you come back after a few hours to find it's still trying to copy a particular file.
The /R and /W switches let you change this behavior.
If there's a way to attach files here, I can share my results.
I also included FastCopy and Windows Copy in my tests and each test was run 10 times. Note, the differences were pretty significant. The 95% confidence intervals had no overlap.
After much testing I have found one of the most effective solutions:
private void openFacebookApp() {
String facebookUrl = "www.facebook.com/XXXXXXXXXX";
String facebookID = "XXXXXXXXX";
try {
int versionCode = getActivity().getApplicationContext().getPackageManager().getPackageInfo("com.facebook.katana", 0).versionCode;
if(!facebookID.isEmpty()) {
// open the Facebook app using facebookID (fb://profile/facebookID or fb://page/facebookID)
Uri uri = Uri.parse("fb://page/" + facebookID);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
} else if (versionCode >= 3002850 && !facebookUrl.isEmpty()) {
// open Facebook app using facebook url
Uri uri = Uri.parse("fb://facewebmodal/f?href=" + facebookUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
} else {
// Facebook is not installed. Open the browser
Uri uri = Uri.parse(facebookUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
}
} catch (PackageManager.NameNotFoundException e) {
// Facebook is not installed. Open the browser
Uri uri = Uri.parse(facebookUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));
}
}
What's your operating system? What version of R are you running: 32-bit or 64-bit? What version of Java do you have installed?
I had a similar error when I first started using the read.xlsx()
function and discovered that my issue (which may or may not be related to yours; at a minimum, this response should be viewed as "try this, too") was related to the incompatability of .xlsx pacakge with 64-bit Java. I'm fairly certain that the .xlsx package requires 32-bit Java.
Use 32-bit R and make sure that 32-bit Java is installed. This may address your issue.
You use ttk.Frame
, bg
option does not work for it. You should create style and apply it to the frame.
from tkinter import *
from tkinter.ttk import *
root = Tk()
s = Style()
s.configure('My.TFrame', background='red')
mail1 = Frame(root, style='My.TFrame')
mail1.place(height=70, width=400, x=83, y=109)
mail1.config()
root.mainloop()
In javascript there are no block-level scopes
only function-level scopes
:
Read this article about javaScript Scoping and Hoisting.
var deferred = $q.defer();
deferred.count = i;
console.log(deferred.count); // 0,1,2,3,4,5 --< all deferred objects
// some code
.success(function(data){
console.log(deferred.count); // 5,5,5,5,5,5 --< only the last deferred object
deferred.resolve(data);
})
var deferred= $q.defer();
inside a for loop it's hoisted to the top of the function, it means that javascript declares this variable on the function scope outside of the for loop
.closure scope

As others have said, you are likely reading past the end of the file as you're only checking for x != ' '
. Instead you also have to check for EOF in the inner loop (but in this case don't use a char, but a sufficiently large type):
while ( ! file.eof() )
{
std::ifstream::int_type x = file.get();
while ( x != ' ' && x != std::ifstream::traits_type::eof() )
{
word += static_cast<char>(x);
x = file.get();
}
std::cout << word << '\n';
word.clear();
}
But then again, you can just employ the stream's streaming operators, which already separate at whitespace (and better account for multiple spaces and other kinds of whitepsace):
void readFile( )
{
std::ifstream file("program.txt");
for(std::string word; file >> word; )
std::cout << word << '\n';
}
And even further, you can employ a standard algorithm to get rid of the manual loop altogether:
#include <algorithm>
#include <iterator>
void readFile( )
{
std::ifstream file("program.txt");
std::copy(std::istream_iterator<std::string>(file),
std::istream_itetator<std::string>(),
std::ostream_iterator<std::string>(std::cout, "\n"));
}
Both async
and defer
scripts begin to download immediately without pausing the parser and both support an optional onload
handler to address the common need to perform initialization which depends on the script.
The difference between async
and defer
centers around when the script is executed. Each async
script executes at the first opportunity after it is finished downloading and before the window’s load event. This means it’s possible (and likely) that async
scripts are not executed in the order in which they occur in the page. Whereas the defer
scripts, on the other hand, are guaranteed to be executed in the order they occur in the page. That execution starts after parsing is completely finished, but before the document’s DOMContentLoaded
event.

I had both pywin32
and pipywin32
installed like suggested in previous answer, but I still did not have a folder ${PYTHON_HOME}\Lib\site-packages\win32
.
This always lead to errors when trying import win32api
.
The simple solution was to uninstall both packages and reinstall pywin32
:
pip uninstall pipywin32
pip uninstall pywin32
pip install pywin32
Then restart Python (and Jupyter).
Now, the win32
folder is there and the import works fine. Problem solved.
One thing to note, if you are using a freestyle job, you won't be able to access build parameters or the Jenkins JVM's environment UNLESS you are using System Groovy Script build steps. I spent hours googling and researching before gathering enough clues to figure that out.
Here is it: http://www.htmlcssvqs.com/8ed/examples/chapter-17/webm-video-with-autoplay-loop.html You have to add the tags: autoplay="autoplay" loop="loop" or just "autoplay" and "loop".
For json to xml use the following Jackson example:
final String str = "{\"name\":\"JSON\",\"integer\":1,\"double\":2.0,\"boolean\":true,\"nested\":{\"id\":42},\"array\":[1,2,3]}";
ObjectMapper jsonMapper = new ObjectMapper();
JsonNode node = jsonMapper.readValue(str, JsonNode.class);
XmlMapper xmlMapper = new XmlMapper();
xmlMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION, true);
xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_1_1, true);
StringWriter w = new StringWriter();
xmlMapper.writeValue(w, node);
System.out.println(w.toString());
Prints:
<?xml version='1.1' encoding='UTF-8'?>
<ObjectNode>
<name>JSON</name>
<integer>1</integer>
<double>2.0</double>
<boolean>true</boolean>
<nested>
<id>42</id>
</nested>
<array>1</array>
<array>2</array>
<array>3</array>
</ObjectNode>
To convert it back (xml to json) take a look at this answer https://stackoverflow.com/a/62468955/1485527 .

IOS 10 Update:
I had a problem with building the fatlib with iphoneos10.0 because the regular expression in the script only expects 9.x and lower and returns 0.0 for ios 10.0
to fix this just replace
SDK_VERSION=$(echo ${SDK_NAME} | grep -o '.\{3\}$')
with
SDK_VERSION=$(echo ${SDK_NAME} | grep -o '[\\.0-9]\{3,4\}$')
alert("xxxxxxxxxxx_456".substr(-3))
caveat: according to mdc, not IE compatible
You can use setattr
name = 'varname'
value = 'something'
setattr(self, name, value) #equivalent to: self.varname= 'something'
print (self.varname)
#will print 'something'
But, since you should inform an object to receive the new variable, this only works inside classes or modules.
You can find a good explanation of why it was replaced by reading A name for the null pointer: nullptr, to quote the paper:
This problem falls into the following categories:
Improve support for library building, by providing a way for users to write less ambiguous code, so that over time library writers will not need to worry about overloading on integral and pointer types.
Improve support for generic programming, by making it easier to express both integer 0 and nullptr unambiguously.
Make C++ easier to teach and learn.

If someone is using react, following will be useful:
https://stackoverflow.com/a/62111884/1015678
const valueSetter = Object.getOwnPropertyDescriptor(this.textInputRef, 'value').set;
const prototype = Object.getPrototypeOf(this.textInputRef);
const prototypeValueSetter = Object.getOwnPropertyDescriptor(prototype, 'value').set;
if (valueSetter && valueSetter !== prototypeValueSetter) {
prototypeValueSetter.call(this.textInputRef, 'new value');
} else {
valueSetter.call(this.textInputRef, 'new value');
}
this.textInputRef.dispatchEvent(new Event('input', { bubbles: true }));
My answer is basically very similar to that of Rubzen. I use the image as the object value, btw. Two versions work for me:
{
"name": "Silver Card",
"logo": require('./golden-card.png'),
or
const goldenCard = require('./golden-card.png');
{ "name": "Silver Card",
"logo": goldenCard,
Without wrappers - but that is different application, too.
I have checked also "import" solution and in few cases it works (what is not surprising, that is applied in pattern App.js in React), but not in case as mine above.
Set return type to Void
instead of void
and return null
// Modify existing method
public static Void displayInt(Integer i) {
System.out.println(i);
return null;
}
OR
// Or use Lambda
myForEach(theList, i -> {System.out.println(i);return null;});
Try this
.Bold { font-weight: bold; }
_x000D_
<span> normal text</span> <br>_x000D_
<span class="Bold"> bold text</span> <br>_x000D_
<span> normal text</span> <spanspan>
_x000D_
The Scanner class is bases on logic implemented in String next(Pattern)
method. The additional API method like nextDouble()
or nextFloat()
. Provide the pattern inside.
Then class description says:
A simple text scanner which can parse primitive types and strings using regular expressions.
A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace. The resulting tokens may then be converted into values of different types using the various next methods.
From the description it can be sad that someone has forgot about char as it is a primitive type for sure.
But the concept of class is to find patterns, a char has no pattern is just next character. And this logic IMHO caused that nextChar has not been implemented.
If you need to read a filed char by char you can used more efficient class.
As far as I know, display: inline-block
is what you probably need. That will make it seem like it's sort of inline but still allow you to use things like margins and such.
Try "pip3 install jupyter", instead of pip. It worked for me.
You can simply make the start_date required using
<input type="submit" value="Submit" required />
You don't even need the checkform() then.

It looks like you are using a custom Kubernetes Cluster (using minikube
, kubeadm
or the like). In this case, there is no LoadBalancer integrated (unlike AWS or Google Cloud). With this default setup, you can only use NodePort
or an Ingress Controller.
With the Ingress Controller you can setup a domain name which maps to your pod; you don't need to give your Service the LoadBalancer
type if you use an Ingress Controller.

This might help someone like me that finds this answer when searching for solutions to how Rails handles the class loading ... I found that I had to define a module
whose name matched my filename appropriately, rather than just defining a class:
In file lib/development_mail_interceptor.rb (Yes, I'm using code from a Railscast :))
module DevelopmentMailInterceptor
class DevelopmentMailInterceptor
def self.delivering_email(message)
message.subject = "intercepted for: #{message.to} #{message.subject}"
message.to = "[email protected]"
end
end
end
works, but it doesn't load if I hadn't put the class inside a module.
I had the same issue and put double quotes around the username and password and it worked: create public database link "opps" identified by "opps" using 'TEST';
Im my case the problem was that I cretead sertificates without entering any data in cli interface. When I regenerated cretificates and enetered all fields: City, State, etc all became fine.

Go to tools
>> nuget
>> console
and type:
Install-Package System.Configuration.ConfigurationManager
If you want a specific version:
Install-Package System.Configuration.ConfigurationManager -Version 4.5.0
Your ConfigurationManager
dll will now be imported and the code will begin to work.
Instead of [(ngModel)] you can use:
// view
<input type="date" #myDate [value]="demoUser.date | date:'yyyy-MM-dd'" (input)="demoUser.date=parseDate($event.target.value)" />
// controller
parseDate(dateString: string): Date {
if (dateString) {
return new Date(dateString);
}
return null;
}
You can also choose not to use parseDate function. In this case the date will be saved as string format like "2016-10-06" instead of Date type (I haven't tried whether this has negative consequences when manipulating the data or saving to database for example).
If you really want DELETE FROM some_table CASCADE;
which means "remove all rows from table some_table
", you can use TRUNCATE
instead of DELETE
and CASCADE
is always supported. However, if you want to use selective delete with a where
clause, TRUNCATE
is not good enough.
USE WITH CARE - This will drop all rows of all tables which have a foreign key constraint on some_table
and all tables that have constraints on those tables, etc.
Postgres supports CASCADE
with TRUNCATE command:
TRUNCATE some_table CASCADE;
Handily this is transactional (i.e. can be rolled back), although it is not fully isolated from other concurrent transactions, and has several other caveats. Read the docs for details.
The os.path...
approach was the 'done thing' in Python 2.
In Python 3, you can find directory of script as follows:
from pathlib import Path
cwd = Path(__file__).parents[0]
It should be like this
$(this).text($(this).text().replace('N/A, ', ''))
Try npm install -g typescript@latest
. You can also use npm update
instead of install, without the latest modifier.
You're using the ajax function incorrectly. Since it's synchronous it'll return the data inline like so:
var remote = $.ajax({
type: "GET",
url: remote_url,
async: false
}).responseText;
You can use two methods in jQuery as given below-
Using jQuery :nth-child Selector You have put the position of an element as its argument which is 2 as you want to select the second li element.
$( "ul li:nth-child(2)" ).click(function(){_x000D_
//do something_x000D_
});
_x000D_
Using jQuery :eq() Selector
If you want to get the exact element, you have to specify the index value of the item. A list element starts with an index 0. To select the 2nd element of li, you have to use 2 as the argument.
$( "ul li:eq(1)" ).click(function(){_x000D_
//do something_x000D_
});
_x000D_
See Example: Get Second Child Element of List in jQuery
It is not at all obvious why one would want to concatenate the (decimal) "ascii values". What is certain is that concatenating them without leading zeroes (or some other padding or a delimiter) is useless -- nothing can be reliably recovered from such an output.

Note that the first 3 outputs are of different length. Note that the fourth result is the same as the first.

To set permanent PuTTY session parameters do:
Create sessions in PuTTY. Name it as "MyskinPROD"
Configure the path for this session to point to "C:\dir\&Y&M&D&T_&H_putty.log".
Create a Windows "Shortcut" to C:...\Putty.exe.
Open "Shortcut" Properties and append "Target" line with parameters as shown below:
"C:\Program Files (x86)\UTL\putty.exe" -ssh -load MyskinPROD user@ServerIP -pw password
Now, your PuTTY shortcut will bring in the "MyskinPROD" configuration every time you open the shortcut.
Check the screenshots and details on how I did it in my environment:
You might want to try this approach:
var str ="{ "name" : "user"}";
var jsonData = JSON.parse(str);
console.log(jsonData.name)
//Array Object
str ="[{ "name" : "user"},{ "name" : "user2"}]";
jsonData = JSON.parse(str);
console.log(jsonData[0].name)
a combination of answers gave me a very fast running time. using the shift method to create new column of next row values, then using the row_iterator function as @alisdt did, but here i changed it from iterrows to itertuples which is 100 times faster.
my script is for iterating dataframe of duplications in different length and add one second for each duplication so they all be unique.
# create new column with shifted values from the departure time column
df['next_column_value'] = df['column_value'].shift(1)
# create row iterator that can 'save' the next row without running for loop
row_iterator = df.itertuples()
# jump to the next row using the row iterator
last = next(row_iterator)
# because pandas does not support items alteration i need to save it as an object
t = last[your_column_num]
# run and update the time duplications with one more second each
for row in row_iterator:
if row.column_value == row.next_column_value:
t = t + add_sec
df_result.at[row.Index, 'column_name'] = t
else:
# here i resetting the 'last' and 't' values
last = row
t = last[your_column_num]
Hope it will help.
well for what its worth now... JsonProperty is ALSO used to specify getter and setter methods for the variable apart from usual serialization and deserialization. For example suppose you have a payload like this:
{
"check": true
}
and a Deserializer class:
public class Check {
@JsonProperty("check") // It is needed else Jackson will look got getCheck method and will fail
private Boolean check;
public Boolean isCheck() {
return check;
}
}
Then in this case JsonProperty annotation is neeeded. However if you also have a method in the class
public class Check {
//@JsonProperty("check") Not needed anymore
private Boolean check;
public Boolean getCheck() {
return check;
}
}
Have a look at this documentation too: http://fasterxml.github.io/jackson-annotations/javadoc/2.3.0/com/fasterxml/jackson/annotation/JsonProperty.html
Addon for Ubuntu (Ubuntu 10.04 LTS (Lucid Lynx)):
The repository moved, but a
pip install -e git+http://github.com/scipy/scipy/#egg=scipy
failed for me... With the following steps, it finally worked out (as root in a virtual environment, where python3
is a link to Python 3.2.2):
install the Ubuntu dependencies (see elaichi), clone NumPy and SciPy:
git clone git://github.com/scipy/scipy.git scipy
git clone git://github.com/numpy/numpy.git numpy
Build NumPy (within the numpy
folder):
python3 setup.py build --fcompiler=gnu95
Install SciPy (within the scipy
folder):
python3 setup.py install
In a linux environment the soft link apparently does not work. you must use the physical path. for instance on my machine I have a softlink at /usr/share/tomacat7/lib/servlet-api.jar
and using this as my classpath argument led to a failed compile with the same error. instead I had to use /usr/share/java/tomcat-servlet-api-3.0.jar
which is the file that the soft link pointed to.
Use set -e
#!/bin/bash
set -e
/bin/command-that-fails
/bin/command-that-fails2
The script will terminate after the first line that fails (returns nonzero exit code). In this case, command-that-fails2 will not run.
If you were to check the return status of every single command, your script would look like this:
#!/bin/bash
# I'm assuming you're using make
cd /project-dir
make
if [[ $? -ne 0 ]] ; then
exit 1
fi
cd /project-dir2
make
if [[ $? -ne 0 ]] ; then
exit 1
fi
With set -e it would look like:
#!/bin/bash
set -e
cd /project-dir
make
cd /project-dir2
make
Any command that fails will cause the entire script to fail and return an exit status you can check with $?. If your script is very long or you're building a lot of stuff it's going to get pretty ugly if you add return status checks everywhere.

If you don't care about loading the file into memory, as of Go 1.16, you can use the os.ReadFile
and bytes.Count
functions.
package main
import (
"log"
"os"
"bytes"
)
func main() {
data, err := os.ReadFile("input.txt")
if err != nil {
log.Fatal(err)
}
n := bytes.Count(data, []byte{'\n'})
fmt.Printf("input.txt has %d lines\n", n)
}
In addition, you need the "AllowOverride Options" directive for this to work. (Apache 2.2.15)
Use \D
to match non-digit characters.
preg_replace('~\D~', '', $str);
You could do this:
import itertools
ids = set(existing_answer.answer.id for existing_answer in existing_question_answers)
answers = itertools.ifilter(lambda x: x.id not in ids, answers)
Read when QuerySets are evaluated and note that it is not good to load the whole result into memory (e.g. via list()
).
Reference: itertools.ifilter
Update with regard to the comment:
There are various ways to do this. One (which is probably not the best one in terms of memory and time) is to do exactly the same :
answer_ids = set(answer.id for answer in answers)
existing_question_answers = filter(lambda x: x.answer.id not in answers_id, existing_question_answers)
package net.itempire.virtualapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Base64;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
public class BaseActivity extends AppCompatActivity {
EditText editText;
TextView textView;
TextView textView2;
TextView textView3;
TextView textView4;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_base);
editText=(EditText)findViewById(R.id.edt);
textView=(TextView) findViewById(R.id.tv1);
textView2=(TextView) findViewById(R.id.tv2);
textView3=(TextView) findViewById(R.id.tv3);
textView4=(TextView) findViewById(R.id.tv4);
textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
textView2.setText(Base64.encodeToString(editText.getText().toString().getBytes(),Base64.DEFAULT));
}
});
textView3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
textView4.setText(new String(Base64.decode(textView2.getText().toString(),Base64.DEFAULT)));
}
});
}
}
Try This. You need pass the authentication to let the server know its a valid user. You need to import these two packages and has to include a jersy jar. If you dont want to include jersy jar then import this package
import sun.misc.BASE64Encoder;
import com.sun.jersey.core.util.Base64;
import sun.net.www.protocol.http.HttpURLConnection;
and then,
String encodedAuthorizedUser = getAuthantication("username", "password");
URL url = new URL("Your Valid Jira URL");
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.setRequestProperty ("Authorization", "Basic " + encodedAuthorizedUser );
public String getAuthantication(String username, String password) {
String auth = new String(Base64.encode(username + ":" + password));
return auth;
}
Alternatively, right after you commit to the wrong branch, perform these steps:
git log
git diff {previous to last commit} {latest commit} > your_changes.patch
git reset --hard origin/{your current branch}
git checkout -b {new branch}
git apply your_changes.patch
I can imagine that there is a simpler approach for steps one and two.
I edited your: Fiddle
html, body{ margin:0; padding:0; overflow:hidden; height:100% }
.header { margin: 0 auto; width:500px; height:30px; background-color:#dadada;}
.wrapper{ margin: 0 auto; width:500px; overflow:scroll; height: 100%;}
Giving the html-tag a 100% height is the solution. I also deleted the container div. You don't need it when your layout stays like this.
Both would return true on Unix systems - in Unix everything is a file, including directories. But to test if that name is taken, you should check both. There might be a regular file named 'foo', which would prevent you from creating a directory name 'foo'.
It's hard to tell what you're going for in that example. exports =
is about exporting from external modules, but the code sample you linked is an internal module.
Rule of thumb: If you write module foo { ... }
, you're writing an internal module; if you write export something something
at top-level in a file, you're writing an external module. It's somewhat rare that you'd actually write export module foo
at top-level (since then you'd be double-nesting the name), and it's even rarer that you'd write module foo
in a file that had a top-level export (since foo
would not be externally visible).
The following things make sense (each scenario delineated by a horizontal rule):
// An internal module named SayHi with an exported function 'foo'
module SayHi {
export function foo() {
console.log("Hi");
}
export class bar { }
}
// N.B. this line could be in another file that has a
// <reference> tag to the file that has 'module SayHi' in it
SayHi.foo();
var b = new SayHi.bar();
file1.ts
// This *file* is an external module because it has a top-level 'export'
export function foo() {
console.log('hi');
}
export class bar { }
file2.ts
// This file is also an external module because it has an 'import' declaration
import f1 = module('file1');
f1.foo();
var b = new f1.bar();
file1.ts
// This will only work in 0.9.0+. This file is an external
// module because it has a top-level 'export'
function f() { }
function g() { }
export = { alpha: f, beta: g };
file2.ts
// This file is also an external module because it has an 'import' declaration
import f1 = require('file1');
f1.alpha(); // invokes f
f1.beta(); // invokes g
Nesting of 'a' will not be possible. However if you badly want to keep the structure and still make it work like the way you want, then override the anchor tag click in javascript /jquery .
so you can have 2 event listeners for the two and control them accordingly.
You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.
Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String
'Assign data to first item in array
compArray(1) = "asdf"
'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"
'Prints "ErrorState"
Debug.Print Computers("Computer Name")
Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx
Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!
Edit:
Sub ArrayExample()

Dim counter As Long
subject = "Example"
counter = Len(subject)
ReDim TestArray(1 To counter) As String
For counter = 1 To Len(subject)
TestArray(counter) = Right(Left(subject, counter), 1)
Next
End Sub
I'll provide you with my vision of somebody who feels very uncomfortable in the Java world, which I assume is also your case.
A workspace is a concept of grouping together:
This happens by creating a directory and putting inside it (you don't have to do it, it's done for you) files that manage to tell Eclipse these information. All you have to do explicitly is to select the folder where these files will be placed. And this folder doesn't need to be the same where you put your source code - preferentially it won't be.
Exploring each item above:
- a set of (somehow) related projects
Eclipse seems to always be opened in association with a particular workspace, i.e., if you are in a workspace A and decide to switch to workspace B (File > Switch Workspaces), Eclipse will close itself and reopen. All projects that were associated with workspace A (and were appearing in the Project Explorer) won't appear anymore and projects associated with workspace B will now appear. So it seems that a project, to be open in Eclipse, MUST be associated to a workspace.
Notice that this doesn't mean that the project source code must be inside the workspace. The workspace will, somehow, have a relation to the physical path of your projects in your disk (anybody knows how? I've looked inside the workspace searching for some file pointing to the projects paths, without success).
This way, a project can be inside more than 1 workspace at a time. So it seems good to keep your workspace and your source code separated.
- some configuration pertaining to all these projects
I heard that something, like the Java compiler version (like 1.7, e.g - I don't know if 'version' is the word here), is a workspace-level configuration. If you have several projects inside your workspace, and compile them inside of Eclipse, all of them will be compiled with the same Java compiler.
- some settings for Eclipse itself
Some things like your key bindings are stored at a workspace-level, also. So, if you define that ctrl+tab will switch tabs in a smart way (not stacking them), this will only be bound to your current workspace. If you want to use the same key binding in another workspace (and I think you want!), it seems that you have to export/import them between workspaces (if that's true, this IDE was built over some really strange premises). Here is a link on this.
It also seems that workspaces are not necessarily compatible between different Eclipse versions. This article suggests that you name your workspaces containing the name of the Eclipse version.
And, more important, once you pick a folder to be your workspace, don't touch any file inside there or you are in for some trouble.
(actually, as I'm writing this, I don't know how to use this in a good way, that's why I was looking for an answer – that I'm trying to assemble here)
Create a folder for your projects:
/projects
Create a folder for each project and group the projects' sub-projects inside of it:
/projects/proj1/subproj1_1
/projects/proj1/subproj1_2
/projects/proj2/subproj2_1
Create a separate folder for your workspaces:
/eclipse-workspaces
Create workspaces for your projects:
/eclipse-workspaces/proj1
/eclipse-workspaces/proj2
I've found this post because I was looking for a way to convert a SQLAlchemy row into a dict. I'm using SqlSoup... but the answer was built by myself, so, if it could helps someone here's my two cents:
a = db.execute('select * from acquisizioni_motes')
b = a.fetchall()
c = b[0]
# and now, finally...
dict(zip(c.keys(), c.values()))

SOAP - "Simple Object Access Protocol"
SOAP is a method of transferring messages, or small amounts of information, over the Internet. SOAP messages are formatted in XML and are typically sent using HTTP (hypertext transfer protocol).
Rest - Representational state transfer
Rest is a simple way of sending and receiving data between client and server and it doesn't have very many standards defined. You can send and receive data as JSON, XML or even plain text. It's light weighted compared to SOAP.
You could give it a try. The problem is that Windows inserts a carriage return as well as a line feed when given a new line. Unix-systems just insert a line feed. So the extra carriage return character could be the reason why your eclipse messes up with the newlines.
Grab one or two files from your project and convert them. You could use Notepad++ to do so. Just open the file, go to Format->Convert to Unix (when you are using windows).
In Linux just try this on a command line:
sed 's/$'"/`echo \\\r`/" yourfile.java > output.java
After several strange errors with relative paths in connectionstring I felt the need to post this here.
When using "|DataDirectory|" or "~" you are not allowed to step up and out using "../" !
Example is using several projects accessing the same localdb file placed in one of the projects.
" ~/../other" and " |DataDirectory|/../other" will fail
Even if it is clearly written at MSDN here the errors it gave where a bit unclear so hard to find and could not find it here at SO.
To specify a directory to search for (binary) libraries, you just use -L
:
-L/data[...]/lib
To specify the actual library name, you use -l
:
-lfoo # (links libfoo.a or libfoo.so)
To specify a directory to search for include files (different from libraries!) you use -I
:
-I/data[...]/lib
So I think what you want is something like
g++ -g -Wall -I/data[...]/lib testing.cpp fileparameters.cpp main.cpp -o test
These compiler flags (amongst others) can also be found at the GNU GCC Command Options manual:
The problem you're having stems from the fact that you're missing android:dividerHeight, which you need, and the fact that you're trying to specify a line weight in your drawable, which you can't do with dividers for some odd reason. Essentially to get your example to work you could do something like the following:
Create your drawable as either a rectangle or a line, either works you just can't try to set any dimensions on it, so either:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="line">
<stroke android:color="#8F8F8F" android:dashWidth="1dp" android:dashGap="1dp" />
</shape>
OR:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#8F8F8F"/>
</shape>
Then create a custom style (just a preference but I like to be able to reuse stuff)
<style name="dividedListStyle" parent="@android:style/Widget.ListView">
<item name="android:cacheColorHint">@android:color/transparent</item>
<item name="android:divider">@drawable/list_divider</item>
<item name="android:dividerHeight">1dp</item>
</style>
Finally declare your list view using the custom style:
<ListView
style="@style/dividedListStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/cashItemsList">
</ListView>
I'm assuming you know how to use these snippets, if not let me know. Basically the answer to your question is that you can't set the divider thickness in the drawable, you have to leave the width undefined there and use android:dividerHeight to set it instead.
See this example :
<?php
echo "<div id='div1'>text</div>"
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title></title>
<script src="js/jquery1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#div1').click(function () {
alert('I clicked');
});
});
</script>
</head>
<body>
</body>
</html>

I know this is a bit old but I think there might be a much simpler solution that requires no additional coding:
Instead of transposing, redimming and transposing again, and if we talk about a two dimensional array, why not just store the values transposed to begin with. In that case redim preserve actually increases the right (second) dimension from the start. Or in other words, to visualise it, why not store in two rows instead of two columns if only the nr of columns can be increased with redim preserve.
the indexes would than be 00-01, 01-11, 02-12, 03-13, 04-14, 05-15 ... 0 25-1 25 etcetera instead of 00-01, 10-11, 20-21, 30-31, 40-41 etcetera.
As long as there is only one dimension that needs to be redimmed-preserved the approach would still work: just put that dimension last.
As only the second (or last) dimension can be preserved while redimming, one could maybe argue that this is how arrays are supposed to be used to begin with. I have not seen this solution anywhere so maybe I'm overlooking something?
(Posted earlier on similar question regarding two dimensions, extended answer here for more dimensions)
In batch, the >
is a redirection sign used to output data into a text file. The compare op's available (And recommended) for cmd are below (quoted from the if /?
help):
where compare-op may be one of:
EQU - equal
NEQ - not equal
LSS - less than
LEQ - less than or equal
GTR - greater than
GEQ - greater than or equal
That should explain what you want. The only other compare-op is ==
which can be switched with the if not
parameter. Other then that rely on these three letter ones.
I tried the chosen answer, but found when I ran a shell script having it, the whole thing was getting printed to screen (similar to how jupyter notebooks print out everything in '''xx'''
quotes) and there was an error message at end. It wasn't doing anything, but: scary. Then I realised while editing it that single-quotes can span multiple lines. So.. lets just assign the block to a variable.
x='
echo "these lines will all become comments."
echo "just make sure you don_t use single-quotes!"

I was creating a mp3 player for android, I wanted to update the current time every 500ms so I did it like this
private void update() {
new android.os.Handler().postDelayed(new Runnable() {
@Override
public void run() {
long cur = player.getCurrentPosition();
long dur = player.getDuration();
currentTime = millisecondsToTime(cur);
currentTimeView.setText(currentTime);
if (cur < dur) {
updatePlayer();
}
// update seekbar
seekBar.setProgress( (int) Math.round((float)cur / (float)dur * 100f));
}
}, 500);
}

Not clear where My_ConnectionString

insert into tablename values(column_name1,column_name2,column_name3);

In Ruby, the Windows version anyways, I just checked and __FILE__
does not contain the full path to the file. Instead it contains the path to the file relative to where it's being executed from.
In PHP __FILE__
is the full path (which in my opinion is preferable). This is why, in order to make your paths portable in Ruby, you really need to use this:
File.expand_path(File.dirname(__FILE__) + "relative/path/to/file")
I should note that in Ruby 1.9.1 __FILE__
contains the full path to the file, the above description was for when I used Ruby 1.8.7.
In order to be compatible with both Ruby 1.8.7 and 1.9.1 (not sure about 1.9) you should require files by using the construct I showed above.

Depends on your contract and your concrete case. Generally it's best to return empty collections, but sometimes (rarely):
null
might mean something more specific;null
.Some concrete examples:
null
would mean the element is missing, while an empty collection would render a redundant (and possibly incorrect) <collection />
public static Random rand = new Random(); // this happens once, and will be great at preventing duplicates
Note, this is not to be used for cryptographic purposes.
List is just an interface. The question is: is your actual List implementation serializable? Speaking about the standard List implementations (ArrayList, LinkedList) from the Java run-time, most of them actually are already.
You can use map
:
List<String> names =
personList.stream()
.map(Person::getName)
.collect(Collectors.toList());
EDIT :
In order to combine the Lists of friend names, you need to use flatMap
:
List<String> friendNames =
personList.stream()
.flatMap(e->e.getFriends().stream())
.collect(Collectors.toList());

From book Mahout in Action, and I think it explains the difference very well:
Classification algorithms are related to, but still quite different from, clustering algorithms such as the k-means algorithm.
Classification algorithms are a form of supervised learning, as opposed to unsupervised learning, which happens with clustering algorithms.
A supervised learning algorithm is one that’s given examples that contain the desired value of a target variable. Unsupervised algorithms aren’t given the desired answer, but instead must find something plausible on their own.
Here are a couple basic examples to get started quick and dirty.
Set variable:
SET(INSTALL_ETC_DIR "etc")
Use variable:
SET(INSTALL_ETC_CROND_DIR "${INSTALL_ETC_DIR}/cron.d")
Set variable:
SET(PROGRAM_SRCS
program.c
program_utils.c
a_lib.c
b_lib.c
config.c
)
Use variable:
add_executable(program "${PROGRAM_SRCS}")
You can't reference an alias except in ORDER BY because SELECT is the second last clause that's evaluated. Two workarounds:
SELECT BalanceDue FROM (
SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
FROM Invoices
) AS x
WHERE BalanceDue > 0;
Or just repeat the expression:
SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
FROM Invoices
WHERE (InvoiceTotal - PaymentTotal - CreditTotal) > 0;
I prefer the latter. If the expression is extremely complex (or costly to calculate) you should probably consider a computed column (and perhaps persisted) instead, especially if a lot of queries refer to this same expression.
PS your fears seem unfounded. In this simple example at least, SQL Server is smart enough to only perform the calculation once, even though you've referenced it twice. Go ahead and compare the plans; you'll see they're identical. If you have a more complex case where you see the expression evaluated multiple times, please post the more complex query and the plans.
Here are 5 example queries that all yield the exact same execution plan:
SELECT LEN(name) + column_id AS x
FROM sys.all_columns
WHERE LEN(name) + column_id > 30;
SELECT x FROM (
SELECT LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE x > 30;
SELECT LEN(name) + column_id AS x
FROM sys.all_columns
WHERE column_id + LEN(name) > 30;
SELECT name, column_id, x FROM (
SELECT name, column_id, LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE x > 30;
SELECT name, column_id, x FROM (
SELECT name, column_id, LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE LEN(name) + column_id > 30;
Resulting plan for all five queries:

As a general rule, always use the more readable code and only refactor if performance is an issue. In this specific case, most recent JDK's will actually optimize the code into the StringBuilder version in any case.
You usually only really need to do it manually if you are doing string concatenation in a loop or in some complex code that the compiler can't easily optimize.
You can solve this issue be adding max-width
:
#element {
width: 100vw;
height: 100vw;
max-width: 100%;
}
When you using CSS to make the wrapper full width using the code width: 100vw;
then you will notice a horizontal scroll in the page, and that happened because the padding
and margin
of html
and body
tags added to the wrapper size, so the solution is to add max-width: 100%
To make it simple, let us say that we can use constructor based dependency injection for mandatory dependencies and setter based injection for optional dependencies. It is a rule of thumb!!
Let's say for example.
If you want to instantiate a class you always do it with its constructor. So if you are using constructor based injection, the only way to instantiate the class is through that constructor. If you pass the dependency through constructor it becomes evident that it is a mandatory dependency.
On the other hand, if you have a setter method in a POJO class, you may or may not set value for your class variable using that setter method. It is completely based on your need. i.e. it is optional. So if you pass the dependency through setter method of a class it implicitly means that it is an optional dependency. Hope this is clear!!
Use location.reload()
:
$('#something').click(function() {
location.reload();
});
The reload()
function takes an optional parameter that can be set to true
to force a reload from the server rather than the cache. The parameter defaults to false

In Your example, apache.yml is tasklist, but not playbook
In depends on desired architecture, You can do one of:
Convert apache.yml to role. Then define tasks in roles/apache/tasks/mail.yml and variables in roles/apache/defaults/mail.yml (vars in defaults can be overriden when role applied)
Set vars in play.yml playbook
play.yml
---
- hosts: 127.0.0.1
connection: local
sudo: false
vars:
url: czxcxz
tasks:
- include: apache.yml
apache.yml
- name: Download apache
shell: wget {{url}}
If you use composer, you can try CsvFileLoader
Unfortunately, setTimeout()
is the only reliable way (not the only way, but the only reliable way) to pause the execution of the script without blocking the UI.
It's not that hard to use actually, instead of writing this:
var x = 1;
// Place mysterious code that blocks the thread for 100 ms.
x = x * 3 + 2;
var y = x / 2;
you use setTimeout()
to rewrite it this way:
var x = 1;
var y = null; // To keep under proper scope
setTimeout(function() {
x = x * 3 + 2;
y = x / 2;
}, 100);
I understand that using setTimeout()
involves more thought than a desirable sleep()
function, but unfortunately the later doesn't exist. Many workarounds are there to try to implement such functions. Some using busy loops:
function sleep(milliseconds) {
var start = new Date().getTime();
for (var i = 0; i < 1e7; i++) {
if ((new Date().getTime() - start) > milliseconds){
break;
}
}
}
Unfortunately, those are workarounds and are likely to cause other problems (such as freezing browsers). It is recommended to simply stick with the recommended way, which is setTimeout()
).
This answer is same as this Mike's answer, and Jeff's answer, both sets redirect_uri
to postmessage
on client side. I want to add more about the server side, and also the special circumstance applying to this configuration.
create-react-app
version 2.1.5Summary: React --> request social auth "code" --> request jwt token to acquire "login" status in terms of your own backend server/database.
responseType="code"
to get an authorization code. (it's not token, not access token!)
react-google-login
mentioned above.{ "provider": "google-oauth2", "code": "your retrieved code here", "redirect_uri": "postmessage" }
REST_SOCIAL_OAUTH_ABSOLUTE_REDIRECT_URI
, REST_SOCIAL_DOMAIN_FROM_ORIGIN
and REST_SOCIAL_OAUTH_REDIRECT_URI
in Django's settings.py
are unnecessary. (They are constants used by Django REST Social Auth) In short, you don't have to setup anything related to redirect url in Django. The "redirect_uri": "postmessage"
in React frontend suffice. This makes sense because the social auth work you have to do on your side is all Ajax-style POST request in frontend, not submitting any form whatsoever, so actually no redirection occur by default. That's why the redirect url becomes useless if you're using the code + JWT flow, and the server-side redirect url setting is not taking any effect.youremailprefix717e248c5b924d60
if your email is [email protected]
. It appends some random string to make a unique username. This is the default behavior, I believe you can customize it and feel free to dig into their documentation.Authorization
header and send request to backend, Django backend will now recognize that as a login, i.e. authenticated user. Of course, if your token expire, you have to refresh it by making another request.Oh my goodness, I've spent more than 6 hours and finally got this right! I believe this is the 1st time I saw this postmessage
thing. Anyone working on a Django + DRF + JWT + Social Auth + React
combination will definitely crash into this. I can't believe none of the article out there mentions this except answers here. But I really hope this post can save you tons of time if you're using the Django + React stack.
I created a version that searches all stylesheets and returns matches as a key/value object. You can also specify startsWith to match child styles.
getStylesBySelector('.pure-form-html', true);
returns:
{
".pure-form-html body": "padding: 0; margin: 0; font-size: 14px; font-family: tahoma;",
".pure-form-html h1": "margin: 0; font-size: 18px; font-family: tahoma;"
}
from:
.pure-form-html body {
padding: 0;
margin: 0;
font-size: 14px;
font-family: tahoma;
}
.pure-form-html h1 {
margin: 0;
font-size: 18px;
font-family: tahoma;
}
The code:
/**
* Get all CSS style blocks matching a CSS selector from stylesheets
* @param {string} className - class name to match
* @param {boolean} startingWith - if true matches all items starting with selector, default = false (exact match only)
* @example getStylesBySelector('pure-form .pure-form-html ')
* @returns {object} key/value object containing matching styles otherwise null
*/
function getStylesBySelector(className, startingWith) {
if (!className || className === '') throw new Error('Please provide a css class name');
var styleSheets = window.document.styleSheets;
var result = {};
// go through all stylesheets in the DOM
for (var i = 0, l = styleSheets.length; i < l; i++) {
var classes = styleSheets[i].rules || styleSheets[i].cssRules || [];
// go through all classes in each document
for (var x = 0, ll = classes.length; x < ll; x++) {
var selector = classes[x].selectorText || '';
var content = classes[x].cssText || classes[x].style.cssText || '';
// if the selector matches
if ((startingWith && selector.indexOf(className) === 0) || selector === className) {
// create an object entry with selector as key and value as content
result[selector] = content.split(/(?:{|})/)[1].trim();
}
}
}
// only return object if we have values, otherwise null
return Object.keys(result).length > 0 ? result : null;
}
I'm using this in production as part of the pure-form project. Hope it helps.
If you want to display text that cannot be edited or selected you can simply use a label
Thanks @Joey. It's what I am looking for.
I just bring some improvements:
function Stop-Processes {
param(
[parameter(Mandatory=$true)] $processName,
$timeout = 5
)
$processList = Get-Process $processName -ErrorAction SilentlyContinue
if ($processList) {
# Try gracefully first
$processList.CloseMainWindow() | Out-Null
# Wait until all processes have terminated or until timeout
for ($i = 0 ; $i -le $timeout; $i ++){
$AllHaveExited = $True
$processList | % {
$process = $_
If (!$process.HasExited){
$AllHaveExited = $False
}
}
If ($AllHaveExited){
Return
}
sleep 1
}
# Else: kill
$processList | Stop-Process -Force
}
}
You can create spinner by these simple steps
first create spinner in xml
<Spinner
android:id="@+id/select"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textColor="#070707"></Spinner>
now create string arary in values
<string-array name="itemselect">
<item>Repurchase</item>
<item>Coupons</item>
</string-array>
now initialized in java file
public class MemberCart_Activity extends AppCompatActivity {
Spinner select;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_member_cart);
select=findViewById(R.id.select);
ArrayAdapter<String> myadapter=new ArrayAdapter<String>(Main_Activity.this,android.R.layout.simple_list_item_1,getResources().getStringArray(R.array.itemselect));
myadapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
select.setAdapter(myadapter);
You can also view package.json
to manually in a text editor, see what packages are dependencies. Use this if npm list
isn't working as a manual alternative.
Another option to fine-tune the line height of an icon is by using a percentage of the vertical-align
property. Usually, 0% is a the bottom, and 100% at the top, but one could use negative values or more than a hundred to create interesting effects.
.my-element i.fa {
vertical-align: 100%; // top
vertical-align: 50%; // middle
vertical-align: 0%; // bottom
}
Could do it with :contains()
selector as well:
$('#toptitle:contains("Profil")').text("New word");
example: http://jsfiddle.net/niklasvh/xPRzr/
I resolved a similar issue by wrapping the query in another query...
Initial query was working find giving individual columns of output, with some of the columns coming from sub queries with Max or Sum function, and other with "distinct" or case substitutions and such.
I encountered the collation error after attempting to create a single field of output with...
select
rtrim(field1)+','+rtrim(field2)+','+...
The query would execute as I wrote it, but the error would occur after saving the sql and reloading it.
Wound up fixing it with something like...
select z.field1+','+z.field2+','+... as OUTPUT_REC
from (select rtrim(field1), rtrim(field2), ... ) z
Some fields are "max" of a subquery, with a case substitution if null and others are date fields, and some are left joins (might be NULL)...in other words, mixed field types. I believe this is the cause of the issue being caused by OS collation and Database collation being slightly different, but by converting all to trimmed strings before the final select, it sorts it out, all in the SQL.
It is not possible to limit the number of visible elements in the select dropdown (if you use it as dropdown box and not as list).
But you could use javascript/jQuery to replace this selectbox with something else, which just looks like a dropdown box. Then you can handle the height of dropdown as you want.
jNice would be a jQuery plugin which has such features. But there also exists many alternatives for that.
$.browser.chrome = /chrom(e|ium)/.test(navigator.userAgent.toLowerCase());
if($.browser.chrome){
............
}
UPDATE:(10x to @Mr. Bacciagalupe)
jQuery has removed $.browser
from 1.9 and their latest release.
But you can still use $.browser as a standalone plugin, found here
The DLL must be present at all times - as the name indicates, a reference only tells VS that you're trying to use stuff from the DLL. In the project file, VS stores the actual path and file name of the referenced DLL. If you move or delete it, VS is not able to find it anymore.
I usually create a libs
folder within my project's folder where I copy DLLs that are not installed to the GAC. Then, I actually add this folder to my project in VS (show hidden files in VS, then right-click and "Include in project"). I then reference the DLLs from the folder, so when checking into source control, the library is also checked in. This makes it much easier when more than one developer will have to change the project.
(Please make sure to set the build type to "none" and "don't copy to output folder" for the DLL in your project.)
PS: I use a German Visual Studio, so the captions I quoted may not exactly match the English version...
HTML
<div id="mydiv" data-myval="10"></div>
JS
var a = $('#mydiv').data('myval'); //getter
$('#mydiv').data('myval',20); //setter
From the reference:
jQuery itself uses the
.data()
method to save information under the names 'events' and 'handle', and also reserves any data name starting with an underscore ('_') for internal use.
It should be noted that jQuery's data()
doesn't change the data
attribute in HTML.
So, if you need to change the data
attribute in HTML, you should use .attr()
instead.
HTML
<div id="outer">
<div id="mydiv" data-myval="10"></div>
</div>
?JS:
alert($('#outer').html()); // alerts <div id="mydiv" data-myval="10"> </div>
var a = $('#mydiv').data('myval'); //getter
$('#mydiv').attr("data-myval","20"); //setter
alert($('#outer').html()); //alerts <div id="mydiv" data-myval="20"> </div>
See this demo
The error is coming as your query is getting formed as
SELECT * FROM Employ where number = parseInt(val);
I dont know which DB you are using but no DB will understand parseInt
.
What you can do is use a variable say temp and store the value of parseInt(val)
in temp variable and make the query as
SELECT * FROM Employ where number = temp;
According to @Data description you can use:
All generated getters and setters will be public. To override the access level, annotate the field or class with an explicit @Setter and/or @Getter annotation. You can also use this annotation (by combining it with AccessLevel.NONE) to suppress generating a getter and/or setter altogether.
Another reason why people might struggle to get Syntax Highlighting working is because they don't have the appropriate syntax package installed. While some default syntax packages come pre-installed (like Swift, C, JS, CSS), others may not be available.
To solve this you can Cmd + Shift + P ? "install Extensions" and look for the language you want to add, say "Scala".
Find the suitable Syntax package, install it and reload. This will pick up the correct syntax for your files with the predefined extension, i.e. .scala
in this case.
On top of that you might want VS Code to treat all files with certain custom extensions as your preferred language of choice. Let's say you want to highlight all *.es
files as JavaScript, then just open "User Settings" (Cmd + Shift + P ? "User Settings") and configure your custom files association like so:
"files.associations": {
"*.es": "javascript"
},
It's a hexadecimal number.
0x6400 translates to 4*16^2 + 6*16^3 = 25600
OK. This is the "most elegant" solution I could come up with on the fly:
boolean allTrue = !Arrays.toString(myArray).contains("f");
Hope that helps!
All of these answers should suffice. However if you don't have a defined width, auto margins will not work.
I have found this nifty little trick to centre some of the more stubborn elements (Particularly images).
.div {
position: absolute;
left: 0;
right: 0;
margin-left: 0;
margin-right: 0;
}
Not certain what the HTML looks like (that would help with answers). If it's
<div class="testimonials content">stuff</div>
then simply remove the space in your css. A la...
.testimonials.content { css here }
UPDATE:
Okay, after seeing HTML see if this works...
.testimonials .wrapper .content { css here }
or just
.testimonials .wrapper { css here }
or
.desc-container .wrapper { css here }
all 3 should work.
document.getElementById(button_id).innerHTML = 'Lock';
In C# (since you tagged it as such) you could use a LINQ expression like this:
List<Control> c = Controls.OfType<TextBox>().Cast<Control>().ToList();
Edit for recursion:
In this example, you first create the list of controls and then call a method to populate it. Since the method is recursive, it doesn't return the list, it just updates it.
List<Control> ControlList = new List<Control>();
private void GetAllControls(Control container)
{
foreach (Control c in container.Controls)
{
GetAllControls(c);
if (c is TextBox) ControlList.Add(c);
}
}
It may be possible to do this in one LINQ statement using the Descendants
function, though I am not as familiar with it. See this page for more information on that.
Edit 2 to return a collection:
As @ProfK suggested, a method that simply returns the desired controls is probably better practice. To illustrate this I have modified the code as follows:
private IEnumerable<Control> GetAllTextBoxControls(Control container)
{
List<Control> controlList = new List<Control>();
foreach (Control c in container.Controls)
{
controlList.AddRange(GetAllTextBoxControls(c));
if (c is TextBox)
controlList.Add(c);
}
return controlList;
}
you just need to write this for getting value in char type.
char c = reader.next().charAt(0);
I also faced the same problem. Then I found a solution after a lot of searching .
The problem was that when we get the datetime object from model or form it is offset aware and if we get the time by system it is offset naive.
So what I did is I got the current time using timezone.now() and import the timezone by from django.utils import timezone and put the USE_TZ = True in your project settings file.
In python3, there is a bytes()
method that is in the same format as encode()
.
str1 = b'hello world'
str2 = bytes("hello world", encoding="UTF-8")
print(str1 == str2) # Returns True
I didn't read anything about this in the docs, but perhaps I wasn't looking in the right place. This way you can explicitly turn strings into byte streams and have it more readable than using encode
and decode
, and without having to prefex b
in front of quotes.
Unfortunately you can't use that tuple assignment syntax in (ECMA|Java)Script.
EDIT: Someone linked to Mozilla/JS 1.7 - this wouldn't work cross-browser but if that is not required then there's your answer.
Use DataFrameWriter.saveAsTable
. (df.write.saveAsTable(...)
) See Spark SQL and DataFrame Guide.

No you cannot force a file that is already committed in the repo to be removed just because it is added to the .gitignore
You have to git rm --cached
to remove the files that you don't want in the repo. ( --cached since you probably want to keep the local copy but remove from the repo. ) So if you want to remove all the exe's from your repo do
git rm --cached /\*.exe
(Note that the asterisk * is quoted from the shell - this lets git, and not the shell, expand the pathnames of files and subdirectories)
I had a similar issue, glob
was returning a list of file names in an arbitrary order but I wanted to step through them in numerical order as indicated by the file name. This is how I achieved it:
My files were returned by glob
something like:
myList = ["c:\tmp\x\123.csv", "c:\tmp\x\44.csv", "c:\tmp\x\101.csv", "c:\tmp\x\102.csv", "c:\tmp\x\12.csv"]
I sorted the list in place, to do this I created a function:
def sortKeyFunc(s):
return int(os.path.basename(s)[:-4])
This function returns the numeric part of the file name and converts to an integer.I then called the sort method on the list as such:
myList.sort(key=sortKeyFunc)
This returned a list as such:
["c:\tmp\x\12.csv", "c:\tmp\x\44.csv", "c:\tmp\x\101.csv", "c:\tmp\x\102.csv", "c:\tmp\x\123.csv"]
Yes lists and tuples are always ordered while dictionaries are not

Menu > Keyboard Preferences > Layouts > Options > Switching to another layout:
Currently there are three ways to write a file:
fs.write(fd, buffer, offset, length, position, callback
)
You need to wait for the callback to ensure that the buffer is written to disk. It's not buffered.
fs.writeFile(filename, data, [encoding], callback)
All data must be stored at the same time; you cannot perform sequential writes.
fs.createWriteStream(path, [options]
)
Creates a WriteStream
, which is convenient because you don't need to wait for a callback. But again, it's not buffered.
A WriteStream
, as the name says, is a stream. A stream by definition is “a buffer” containing data which moves in one direction (source ? destination). But a writable stream is not necessarily “buffered”. A stream is “buffered” when you write n
times, and at time n+1
, the stream sends the buffer to the kernel (because it's full and needs to be flushed).
In other words: “A buffer” is the object. Whether or not it “is buffered” is a property of that object.
If you look at the code, the WriteStream
inherits from a writable Stream
object. If you pay attention, you’ll see how they flush the content; they don't have any buffering system.
If you write a string, it’s converted to a buffer, and then sent to the native layer and written to disk. When writing strings, they're not filling up any buffer. So, if you do:
write("a")
write("b")
write("c")
You're doing:
fs.write(new Buffer("a"))
fs.write(new Buffer("b"))
fs.write(new Buffer("c"))
That’s three calls to the I/O layer. Although you're using “buffers”, the data is not buffered. A buffered stream would do: fs.write(new Buffer ("abc"))
, one call to the I/O layer.
As of now, in Node.js v0.12 (stable version announced 02/06/2015) now supports two functions:
cork()
and
uncork()
. It seems that these functions will finally allow you to buffer/flush the write calls.
For example, in Java there are some classes that provide buffered streams (BufferedOutputStream
, BufferedWriter
...). If you write three bytes, these bytes will be stored in the buffer (memory) instead of doing an I/O call just for three bytes. When the buffer is full the content is flushed and saved to disk. This improves performance.
I'm not discovering anything, just remembering how a disk access should be done.
Like this:
border: 1px solid black;
Why it didn't work? because:
Always declare the border-style (solid in my example) property before the border-width property. An element must have borders before you can change the color.
