Python doesn't really have either concept.
It uses duck typing, which removed the need for interfaces (at least for the computer :-))
Python <= 2.5: Base classes obviously exist, but there is no explicit way to mark a method as 'pure virtual', so the class isn't really abstract.
Python >= 2.6: Abstract base classes do exist (http://docs.python.org/library/abc.html). And allow you to specify methods that must be implemented in subclasses. I don't much like the syntax, but the feature is there. Most of the time it's probably better to use duck typing from the 'using' client side.

You can modify Kendall Hopkins' answer a little in the switch statement to get a pretty clean looking and nicely indented printout by passing a json string into the following:
function prettyPrint( $json ){
$result = '';
$level = 0;
$in_quotes = false;
$in_escape = false;
$ends_line_level = NULL;
$json_length = strlen( $json );
for( $i = 0; $i < $json_length; $i++ ) {
$char = $json[$i];
$new_line_level = NULL;
$post = "";
if( $ends_line_level !== NULL ) {
$new_line_level = $ends_line_level;
$ends_line_level = NULL;
}
if ( $in_escape ) {
$in_escape = false;
} else if( $char === '"' ) {
$in_quotes = !$in_quotes;
} else if( ! $in_quotes ) {
switch( $char ) {
case '}': case ']':
$level--;
$ends_line_level = NULL;
$new_line_level = $level;
$char.="<br>";
for($index=0;$index<$level-1;$index++){$char.="-----";}
break;
case '{': case '[':
$level++;
$char.="<br>";
for($index=0;$index<$level;$index++){$char.="-----";}
break;
case ',':
$ends_line_level = $level;
$char.="<br>";
for($index=0;$index<$level;$index++){$char.="-----";}
break;
case ':':
$post = " ";
break;
case "\t": case "\n": case "\r":
$char = "";
$ends_line_level = $new_line_level;
$new_line_level = NULL;
break;
}
} else if ( $char === '\\' ) {
$in_escape = true;
}
if( $new_line_level !== NULL ) {
$result .= "\n".str_repeat( "\t", $new_line_level );
}
$result .= $char.$post;
}
echo "RESULTS ARE: <br><br>$result";
return $result;
}
Now just run the function prettyPrint( $your_json_string ); inline in your php and enjoy the printout. If you're a minimalist and don't like brackets for some reason, you can get rid of those easily by replacing the $char.="<br>";
with $char="<br>";
in the top three switch cases on $char. Here's what you get for a google maps API call for the city of Calgary

Although ANSI C does not have this mechanism, it is possible to use itoa() as a shortcut:
char buffer [33];
itoa (i,buffer,2);
printf ("binary: %s\n",buffer);
Here's the origin:
It is non-standard C, but K&R mentioned the implementation in the C book, so it should be quite common. It should be in stdlib.h.
create LOGIN guest WITH PASSWORD='guest@123', CHECK_POLICY = OFF;
Be sure when you want to exceute the following
DENY VIEW ANY DATABASE TO guest;
ALTER AUTHORIZATION ON DATABASE::BiddingSystemDB TO guest
Selected Database should be Master
You can also use this very simplified form:
@Html.ActionLink("Come back to Home", "Index", "Home")
Where :
Come back to Home
is the text that will appear on the page
Index
is the view name
Home
is the controller name
The syntax for REPLACE:
REPLACE (string_expression,string_pattern,string_replacement)
So that the SQL you need should be:
UPDATE [DataTable] SET [ColumnValue] = REPLACE([ColumnValue], 'domain2', 'domain1')
You are running Python 2 code on Python 3. In Python 3, the module has been renamed to http.client
.
You could try to run the 2to3
tool on your code, and try to have it translated automatically. References to httplib
will automatically be rewritten to use http.client
instead.
Your code works. If you don't have any output, you may have "forgotten" to add some values to the list:
// add values
list.add("one");
list.add("two");
// your code
for (String object: list) {
System.out.println(object);
}
If you mark your entity with @DynamicInsert
e.g.
@Entity
@DynamicInsert
@Table(name = "TABLE_NAME")
public class ClassName implements Serializable {
Hibernate will generate SQL without null
values. Then the database will insert its own default value. This does have performance implications See [Dynamic Insert][1].
Double.TryParse IMO.
It is easier for you to handle, You'll know exactly where the error occurred.
Then you can deal with it how you see fit if it returns false (i.e could not convert).
|| is the boolean OR operator. As in javascript, undefined, null, 0, false are considered as falsy values.
It simply means
true || true = true
false || true = true
true || false = true
false || false = false
undefined || "value" = "value"
"value" || undefined = "value"
null || "value" = "value"
"value" || null = "value"
0 || "value" = "value"
"value" || 0 = "value"
false || "value" = "value"
"value" || false = "value"
There are several solutions depending on what you need...
If you want to add a custom header (or set of headers) to an individual request then just add the headers
property:
// Request with custom header
$.ajax({
url: 'foo/bar',
headers: { 'x-my-custom-header': 'some value' }
});
If you want to add a default header (or set of headers) to every request then use $.ajaxSetup()
:
$.ajaxSetup({
headers: { 'x-my-custom-header': 'some value' }
});
// Sends your custom header
$.ajax({ url: 'foo/bar' });
// Overwrites the default header with a new header
$.ajax({ url: 'foo/bar', headers: { 'x-some-other-header': 'some value' } });
If you want to add a header (or set of headers) to every request then use the beforeSend
hook with $.ajaxSetup()
:
$.ajaxSetup({
beforeSend: function(xhr) {
xhr.setRequestHeader('x-my-custom-header', 'some value');
}
});
// Sends your custom header
$.ajax({ url: 'foo/bar' });
// Sends both custom headers
$.ajax({ url: 'foo/bar', headers: { 'x-some-other-header': 'some value' } });
Edit (more info): One thing to be aware of is that with ajaxSetup
you can only define one set of default headers and you can only define one beforeSend
. If you call ajaxSetup
multiple times, only the last set of headers will be sent and only the last before-send callback will execute.
Try using a div tag and block for span!
<div>
<span style="padding-right:3px; padding-top: 3px; display:block;">
<img class="manImg" src="images/ico_mandatory.gif"></img>
</span>
</div>
From the use of 8080 I'm assuming you are using a tomcat servlet container to serve your rest api. If this is the case you can also consider to have your webserver proxy the requests to the servlet container.
With apache you would typically use mod_jk (although there are other alternatives) to serve the api trough the web server behind port 80 instead of 8080 which would solve the cross domain issue.
This is common practice, have the 'static' content in the webserver and dynamic content in the container, but both served from behind the same domain.
The url for the rest api would be http://localhost/restws/json/product/get
Here a description on how to use mod_jk to connect apache to tomcat: http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html
Starting with .NET 4.0 you can use ExpressionVisitor
to find properties:
class ExprVisitor : ExpressionVisitor {
public bool IsFound { get; private set; }
public string MemberName { get; private set; }
public Type MemberType { get; private set; }
protected override Expression VisitMember(MemberExpression node) {
if (!IsFound && node.Member.MemberType == MemberTypes.Property) {
IsFound = true;
MemberName = node.Member.Name;
MemberType = node.Type;
}
return base.VisitMember(node);
}
}
Here is how you use this visitor:
var visitor = new ExprVisitor();
visitor.Visit(expr);
if (visitor.IsFound) {
Console.WriteLine("First property in the expression tree: Name={0}, Type={1}", visitor.MemberName, visitor.MemberType.FullName);
} else {
Console.WriteLine("No properties found.");
}
there is another technique
use
background-size:cover
That is it full set of css is
body {
background: url('images/body-bg.jpg') no-repeat center center fixed;
-moz-background-size: cover;
-webkit-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
Latest browsers support the default property.
If you really need this you can achieve your goal with help of separate table for sequencing (if you don't mind) and a trigger.
Tables
CREATE TABLE table1_seq
(
id INT NOT NULL AUTO_INCREMENT PRIMARY KEY
);
CREATE TABLE table1
(
id VARCHAR(7) NOT NULL PRIMARY KEY DEFAULT '0', name VARCHAR(30)
);
Now the trigger
DELIMITER $$
CREATE TRIGGER tg_table1_insert
BEFORE INSERT ON table1
FOR EACH ROW
BEGIN
INSERT INTO table1_seq VALUES (NULL);
SET NEW.id = CONCAT('LHPL', LPAD(LAST_INSERT_ID(), 3, '0'));
END$$
DELIMITER ;
Then you just insert rows to table1
INSERT INTO Table1 (name)
VALUES ('Jhon'), ('Mark');
And you'll have
| ID | NAME | ------------------ | LHPL001 | Jhon | | LHPL002 | Mark |
Here is SQLFiddle demo
You need this:
CONCAT(REPLACE(FORMAT(number,0),',','.'),',',SUBSTRING_INDEX(FORMAT(number,2),'.',-1))
Remove the multiple="multiple" attribute and add SIZE=6 with the number of elements you want
you may want to check this site
After MS SQL Server 2012, you can use window function too.
SELECT column_name,
COUNT(column_name) OVER (Partition by column_name)
FROM table_name group by column_name ;
localhost is a special hostname that almost always resolves to 127.0.0.1. If you ask someone else to connect to http://localhost
they'll be connecting to their computer instead or yours.
To share your web server with someone else you'll need to find your IP address or your hostname and provide that to them instead. On windows you can find this with ipconfig /all
on a command line.
You'll also need to make sure any firewalls you may have configured allow traffic on port 80 to connect to the WAMP server.
You could use CSS for this and create classes for the elements. So you'd have something like this
p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }
Then your HTML would read:
<p class="detail">My Name is: <span class="name">Tintinecute</span> </p>
It's a lot neater then inline stylesheets, is easier to maintain and provides greater reuse.
Here's the complete HTML to demonstrate what I mean:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<style type="text/css">
p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }
</style>
</head>
<body>
<p class="detail">My Name is: <span class="name">Tintinecute</span> </p>
</body>
</html>
You'll see that I have the stylesheet classes in a style tag in the header, and then I only apply those classes in the code such as <p class="detail"> ... </p>
. Go through the w3schools tutorial, it will only take a couple of hours and will really turn you around when it comes to styling your HTML elements. If you cut and paste that into an HTML document you can edit the styles and see what effect they have when you open the file in a browser. Experimenting like this is a great way to learn.
I just encountered the same problem myself.
... = reader["myYear"] as int?;
works and is clean.
It works with any type without an issue. If the result is DBNull, it returns null as the conversion fails.

I'm not sure if it is the fastest solution but i preferred it for simplicity and for not using regex (i just don't like using them!)
Yes. See the relevant page on the R wiki. Short answer: read.xls
from the gdata
package works most of the time (although you need to have Perl installed on your system -- usually already true on MacOS and Linux, but takes an extra step on Windows, i.e. see http://strawberryperl.com/). There are various caveats, and alternatives, listed on the R wiki page.
The only reason I see not to do this directly is that you may want to examine the spreadsheet to see if it has glitches (weird headers, multiple worksheets [you can only read one at a time, although you can obviously loop over them all], included plots, etc.). But for a well-formed, rectangular spreadsheet with plain numbers and character data (i.e., not comma-formatted numbers, dates, formulas with divide-by-zero errors, missing values, etc. etc. ..) I generally have no problem with this process.
There seem to be a lot of confusion which was addressed only in comments by elclanrs and raina77ow, so let me post a clarifying answer.
From "string.splice
" one may expect that it, like the one for arrays:
The problem is, the 3d requirement can not be fulfilled because strings are immutable (related: 1, 2), I've found the most dedicated comment here:
In JavaScript strings are primitive value types and not objects (spec). In fact, as of ES5, they're one of the only 5 value types alongside
null
,undefined
,number
andboolean
. Strings are assigned by value and not by reference and are passed as such. Thus, strings are not just immutable, they are a value. Changing the string"hello"
to be"world"
is like deciding that from now on the number 3 is the number 4... it makes no sense.
So, with that in account, one may expect the "string.splice
" thing to only:
which is what substr
does; or, alternatively,
which is the subject of the next section.
If you care about optimizing, you should probably use the Mike's implementation:
String.prototype.splice = function(index, count, add) {
if (index < 0) {
index += this.length;
if (index < 0)
index = 0;
}
return this.slice(0, index) + (add || "") + this.slice(index + count);
}
Treating the out-of-boundaries index may vary, though. Depending on your needs, you may want:
if (index < 0) {
index += this.length;
if (index < 0)
index = 0;
}
if (index >= this.length) {
index -= this.length;
if (index >= this.length)
index = this.length - 1;
}
or even
index = index % this.length;
if (index < 0)
index = this.length + index;
If you don't care about performance, you may want to adapt Kumar's suggestion which is more straight-forward:
String.prototype.splice = function(index, count, add) {
var chars = this.split('');
chars.splice(index, count, add);
return chars.join('');
}
The difference in performances increases drastically with the length of the string. jsperf shows, that for strings with the length of 10 the latter solution (splitting & joining) is twice slower than the former solution (using slice), for 100-letter strings it's x5 and for 1000-letter strings it's x50, in Ops/sec it's:
10 letters 100 letters 1000 letters
slice implementation 1.25 M 2.00 M 1.91 M
split implementation 0.63 M 0.22 M 0.04 M
note that I've changed the 1st and 2d arguments when moving from 10 letters to 100 letters (still I'm surprised that the test for 100 letters runs faster than that for 10 letters).
As Dave Webb said:
Here is my working code snippet printing the pixel colours from an image:
import os, sys import Image im = Image.open("image.jpg") x = 3 y = 4 pix = im.load() print pix[x,y]
Usually, we want to divide our vector into a number of intervals. In this case, you can use a function where (a) is a vector and (b) is the number of intervals. (Let's suppose you want 4 intervals)
a <- 1:10
b <- 4
FunctionIntervalM <- function(a,b) {
seq(from=min(a), to = max(a), by = (max(a)-min(a))/b)
}
FunctionIntervalM(a,b)
# 1.00 3.25 5.50 7.75 10.00
Therefore you have 4 intervals:
1.00 - 3.25
3.25 - 5.50
5.50 - 7.75
7.75 - 10.00
You can also use a cut function
cut(a, 4)
# (0.991,3.25] (0.991,3.25] (0.991,3.25] (3.25,5.5] (3.25,5.5] (5.5,7.75]
# (5.5,7.75] (7.75,10] (7.75,10] (7.75,10]
#Levels: (0.991,3.25] (3.25,5.5] (5.5,7.75] (7.75,10]
they're both going to be stored independently, however if you want to make it clear to other developers you might want to wrap them up in namespaces.
Type in console as root:
apt-get update && apt-get install php5-curl

Sorry I missread.
1st, check your DNS config and if you can ping any host at all,
ping google.com
ping zm.archive.ubuntu.com
If it does not work, check /etc/resolv.conf
or /etc/network/resolv.conf
, if not, change your apt-source to a different one.
/etc/apt/sources.list
Mirrors: http://www.debian.org/mirror/list
You should not use Ubuntu sources on Debian and vice versa.
SELECT DATENAME(MONTH, GETDATE())
+ RIGHT(CONVERT(VARCHAR(12), GETDATE(), 107), 9) AS [Month DD, YYYY]
OR Date without Comma Between date and year, you can use the following
SELECT DATENAME(MONTH, GETDATE()) + ' ' + CAST(DAY(GETDATE()) AS VARCHAR(2))
+ ' ' + CAST(YEAR(GETDATE()) AS VARCHAR(4)) AS [Month DD YYYY]
You can search for any scalar condition with:
>>> a = np.asarray([0,1,2,3,4])
>>> a == 0 # or whatver
array([ True, False, False, False, False], dtype=bool)
Which will give back the array as an boolean mask of the condition.
You are binding the click
event to anchors with an href attribute with value sign_new
.
Either bind anchors with class sign_new
or bind anchors with href value #sign_up
. I would prefer the former.
You can also try the fetch
function and the no-cors
mode. I sometimes find it easier to configure it than Angular's built-in http module. You can right-click requests in the Chrome Dev tools network tab and copy them in the fetch syntax, which is great.
import { from } from 'rxjs';
// ...
result = from( // wrap the fetch in a from if you need an rxjs Observable
fetch(
this.baseurl,
{
body: JSON.stringify(data)
headers: {
'Content-Type': 'application/json',
},
method: 'POST',
mode: 'no-cors'
}
)
);
I'll suggest different approach, If the order of the items inside the list is not important at extraction (and each item should be selected only once), then instead of a List
you can use a ConcurrentBag
which is a thread-safe, unordered collection of objects:
var bag = new ConcurrentBag<string>();
bag.Add("Foo");
bag.Add("Boo");
bag.Add("Zoo");
The EventHandler:
string result;
if (bag.TryTake(out result))
{
MessageBox.Show(result);
}
The TryTake
will attempt to extract an "random" object from the unordered collection.
You don't need an index match formula. You can use this array formula. You have to press CTL + SHIFT + ENTER after you enter the formula.
=MAX(IF((A1:A6=A10)*(B1:B6=B10),C1:F6))
SNAPSHOT
If you're using SQL Server, you can set the value of bit fields with 0 and 1
or
'true' and 'false'
(yes, using strings)
...your_bit_field='false'... => equivalent to 0
In case you want to do it yourself..
List<Integer> commons = new ArrayList<Integer>();
for (Integer igr : group1) {
if (group2.contains(igr)) {
commons.add(igr);
}
}
System.out.println("Common elements are :: -");
for (Integer igr : commons) {

I have faced with the same issue. The resolve: - Window-->Preferences-->Java-->Installed JREs-->Add... - Right click on your project-->Build Path-->Configure Build Path-->Add library-->JRE system library-->next-->WorkSpace Default JRE
Ad this line inside the OnCreate event on MainActivity (Xamarin)

From another search. Worked for me!
"You can use Visual Studio 2010 and it does support it, provided your OS supports .NET 4.5.
Right click on your solution to add a reference (as you do). When the dialog box shows, select browse, then navigate to the following folder:

You will find it there."
Got a solution that runs. Don't know if it is optimal though. What I do is to split the string according to http://blogs.oracle.com/aramamoo/2010/05/how_to_split_comma_separated_string_and_pass_to_in_clause_of_select_statement.html
Using:
select regexp_substr(' 1, 2 , 3 ','[^,]+', 1, level) from dual
connect by regexp_substr('1 , 2 , 3 ', '[^,]+', 1, level) is not null;
So my final code looks like this ($bp_gr1'
are strings like 1,2,3
):
UPDATE TAB1
SET BUDGPOST_GR1 =
CASE
WHEN ( BUDGPOST IN (SELECT REGEXP_SUBSTR ( '$BP_GR1',
'[^,]+',
1,
LEVEL )
FROM DUAL
CONNECT BY REGEXP_SUBSTR ( '$BP_GR1',
'[^,]+',
1,
LEVEL )
IS NOT NULL) )
THEN
'BP_GR1'
WHEN ( BUDGPOST IN (SELECT REGEXP_SUBSTR ( ' $BP_GR2',
'[^,]+',
1,
LEVEL )
FROM DUAL
CONNECT BY REGEXP_SUBSTR ( '$BP_GR2',
'[^,]+',
1,
LEVEL )
IS NOT NULL) )
THEN
'BP_GR2'
WHEN ( BUDGPOST IN (SELECT REGEXP_SUBSTR ( ' $BP_GR3',
'[^,]+',
1,
LEVEL )
FROM DUAL
CONNECT BY REGEXP_SUBSTR ( '$BP_GR3',
'[^,]+',
1,
LEVEL )
IS NOT NULL) )
THEN
'BP_GR3'
WHEN ( BUDGPOST IN (SELECT REGEXP_SUBSTR ( '$BP_GR4',
'[^,]+',
1,
LEVEL )
FROM DUAL
CONNECT BY REGEXP_SUBSTR ( '$BP_GR4',
'[^,]+',
1,

IS NOT NULL) )
THEN

END;
Is there a way to make it run faster?
Some basic differences can be written in short:
MVC:
Traditional MVC is where there is a
MVP:
Similar to traditional MVC but Controller is replaced by Presenter. But the Presenter, unlike Controller is responsible for changing the view as well. The view usually does not call the presenter.
MVVM
The difference here is the presence of View Model. It is kind of an implementation of Observer Design Pattern, where changes in the model are represented in the view as well, by the VM. Eg: If a slider is changed, not only the model is updated but the data which may be a text, that is displayed in the view is updated as well. So there is a two-way data binding.
There is also another reason. In my case, I had copy an index.cshtml file to web root folder (outside the Views folder) as a backup from remote server.
So, I kept changing my /views/web.config, kept changing my /views/home/index.cshtml and error kept happening... until found out the /index.cshtml outside the views folder, deleted it and sure, it all went back to normal!
In addition to backslash, if a line ends with |
or &&
or ||
, it will be continued on the next line.
If you need to do this programmatically, it's a little more involved than just getting the answer into your brain. I have a script that I use to sign all of our apps, but each use a different key. Here are 2 ways to get just the Package Name as output so you can put it in a variable or do whatever you need with it.
Example output: com.example.appname
(and nothing more)
aapt
- Android Asset Packaging Tool, part of the SDK Tools download
Using awk
specify '
as the Field Separator, search for a line with package: name=
, and print only the 2nd "field" in the line:
aapt dump badging /path/to/file.apk | awk -v FS="'" '/package: name=/{print $2}'
A weakness of this method is that it relies on aapt to output the package information fields in the same order:
package: name='com.example.appname' versionCode='3461' versionName='2.2.4' platformBuildVersionName='4.2.2-1425461'
We have no commitments from the developers to maintain this format.
Using awk
specify "
as the Field Separator, search for a line with package=
, and print only the 2nd "field" in the line:
aapt list -a /path/to/file.apk | awk -v FS='"' '/package=/{print $2}'
A weakness of this method is that it relies on aapt to output package=
only in the Android Manifest:
section of the output. We have no commitments from the developers to maintain this format.
Expand the apk file with apktool d
and read the AndroidManifest.xml.
This would be the best method, but the AndroidManifest.xml is a binary file and all the SO answers I see for converting it to text do not work. (Using apktool d
instead of a simple unzip
is supposed to do this for you, but it does not.) Please comment if you have an solution to this issue
This is how you can create a simple observable for static data.
let observable = Observable.create(observer => {
setTimeout(() => {
let users = [
{username:"balwant.padwal",city:"pune"},
{username:"test",city:"mumbai"}]
observer.next(users); // This method same as resolve() method from Angular 1
console.log("am done");
observer.complete();//to show we are done with our processing
// observer.error(new Error("error message"));
}, 2000);
})
to subscribe to it is very easy
observable.subscribe((data)=>{
console.log(data); // users array display
});
I hope this answer is helpful. We can use HTTP call instead static data.
I like overriding jQuery widgets.
(function ($) {
$.widget("sauti.dialog", $.ui.dialog, {
options: {
headerVisible: false
},
_create: function () {
// ready to generate button
this._super("_create"); // for 18 would be $.Widget.prototype._create.call(this);
// decide if header is visible
if(this.options.headerVisible == false)
this.uiDialogTitlebar.hide();
},
_setOption: function (key, value) {
this._super(key, value); // for 1.8 would be $.Widget.prototype._setOption.apply( this, arguments );
if (key === "headerVisible") {
if (key == false)
this.uiDialogTitlebar.hide();
else
this.uiDialogTitlebar.show();
return;
}
}
});
})(jQuery);
So you can now setup if you want to show title bar or not
$('#mydialog').dialog({
headerVisible: false // or true
});
Firstly, you need to put session_start();
before any output to the browser, normally at the top of the page. Have a look at the manual.
Second, this won't affect your results, but these lines aren't being used anywhere and should be removed:
$usr = "admin";
$psw = "password";
$username = '$_POST[username]';
$password = '$_POST[password]';
...and the last two lines there wouldn't work, you need to put the quotes inside the square brackets:
$username = $_POST['username'];
If you put session_start()
at the top of your page (i.e. before the <html>
tag etc), this should work fine.
Works with Chrome 84.0.4147.105
1. Assign text type to password fields and add a class, e.g. "fakepasswordtype"
<input type="text" class="fakepasswordtype" name="password1">
<input type="text" class="fakepasswordtype" name="password2">
2. Then use jQuery to change the type back to password the moment when first input is done
jQuery(document).ready(function($) {
$('.fakepasswordtype').on('input', function(e){
$(this).prop('type', 'password');
});
});
This stopped Chrome from it's nasty ugly behavior from auto filling.
.NET XSLT implementation allows to write custom managed functions in the stylesheet. For lower-case() it can be:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:utils="urn:myExtension" exclude-result-prefixes="msxsl">
<xsl:output method="xml" indent="yes"/>
<msxsl:script implements-prefix="utils" language="C#">
<![CDATA[
public string ToLower(string stringValue)
{
string result = String.Empty;
if(!String.IsNullOrEmpty(stringValue))
{
result = stringValue.ToLower();
}
return result;
}
]]>
</msxsl:script>
<!-- using of our custom function -->
<lowercaseValue>
<xsl:value-of select="utils:ToLower($myParam)"/>
</lowercaseValue>
Assume, that can be slow, but still acceptable.
Do not forget to enable embedded scripts support for transform:
// Create the XsltSettings object with script enabled.
XsltSettings xsltSettings = new XsltSettings(false, true);
XslCompiledTransform xslt = new XslCompiledTransform();
// Load stylesheet
xslt.Load(xsltPath, xsltSettings, new XmlUrlResolver());
hi i got the same problem.. add 0.71 to excel cell width value and give that value to the
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);
eg: A Column width = 3.71 (excel value)
give column width = 4.42
will give the output file with same cell width.
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(4.42);
hope this help
#include <vector>
#include <algorithm>
int main()
{
int arr[5] = {4, 1, 3, 2, 6};
int x = -1;
std::vector<int> testVector(arr, arr + sizeof(arr) / sizeof(int) );
std::vector<int>::iterator it = std::find(testVector.begin(), testVector.end(), 3);
if (it != testVector.end())
{
x = it - testVector.begin();
}
return 0;
}
Or you can just build a vector in a normal way, without creating it from an array of ints and then use the same solution as shown in my example.
NOW()
is used to insert the current date and time in the MySQL table. All fields with datatypes DATETIME, DATE, TIME & TIMESTAMP
work good with this function.
YYYY-MM-DD HH:mm:SS
Demonstration:
Following code shows the usage of NOW()
INSERT INTO auto_ins
(MySQL_Function, DateTime, Date, Time, Year, TimeStamp)
VALUES
(“NOW()”, NOW(), NOW(), NOW(), NOW(), NOW());
Update: since the time I answered this there has been a lot of work on this look at Apache Arrow for a better read and write of parquet. Also: http://wesmckinney.com/blog/python-parquet-multithreading/
There is a python parquet reader that works relatively well: https://github.com/jcrobak/parquet-python
It will create python objects and then you will have to move them to a Pandas DataFrame so the process will be slower than pd.read_csv
for example.
public void UploadFtpFile(string folderName, string fileName)
{
FtpWebRequest request;
string folderName;
string fileName;
string absoluteFileName = Path.GetFileName(fileName);
request = WebRequest.Create(new Uri(string.Format(@"ftp://{0}/{1}/{2}", "127.0.0.1", folderName, absoluteFileName))) as FtpWebRequest;
request.Method = WebRequestMethods.Ftp.UploadFile;
request.UseBinary = 1;
request.UsePassive = 1;
request.KeepAlive = 1;
request.Credentials = new NetworkCredential(user, pass);
request.ConnectionGroupName = "group";
using (FileStream fs = File.OpenRead(fileName))
{
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
Stream requestStream = request.GetRequestStream();
requestStream.Write(buffer, 0, buffer.Length);
requestStream.Flush();
requestStream.Close();
}
}
How to use
UploadFtpFile("testFolder", "E:\\filesToUpload\\test.img");
use this in your foreach
and you only need to create folder one time
to create a folder
request = WebRequest.Create(new Uri(string.Format(@"ftp://{0}/{1}/", "127.0.0.1", "testFolder"))) as FtpWebRequest;
request.Method = WebRequestMethods.Ftp.MakeDirectory;
FtpWebResponse ftpResponse = (FtpWebResponse)request.GetResponse();
... and so you should do something like this:
set(tuple ((a,b) for a in range(3)) for b in range(3))
... and if needed convert back to list
Enabling "Ensure right margin is not exceeded" doesn't work for me in Intellij IDEA 2018.2. I have found the workaround, we need to change every elements below from "Do not wrap" to "Wrap if long".
After that, we can preview what kind of wrap type will be changed by looking into right panel. If we are satisfied, Click "OK" or "Apply" to apply the changes. Finally we need a mannual format by using CTRL+ ALT+ L in Windows and Command+ Shift+ L in MacOS.
If you want to create dynamically/runtime data table in VB.Net then you should follow these steps as mentioned below :
For eg.
Dim dt As New DataTable
dt.Columns.Add("Id", GetType(Integer))
dt.Columns.Add("FirstName", GetType(String))
dt.Columns.Add("LastName", GetType(String))
dt.Rows.Add(1, "Test", "data")
dt.Rows.Add(15, "Robert", "Wich")
dt.Rows.Add(18, "Merry", "Cylon")
dt.Rows.Add(30, "Tim", "Burst")
This is how I feed my table with data retrieved by ajax (not sure if this is the best practice tough, but it feels intuitive and works well):
/* initialise table */
oTable1 = $( '.tables table' ).dataTable
( {
'sPaginationType': 'full_numbers',
'bLengthChange': false,
'aaData': [],
'aoColumns': [{"sTitle": "Tables"}],
'bAutoWidth': true
} );
/*retrieve data*/
function getArr( conf_csv_path )
{
$.ajax
({
url : 'my_url'
success : function( obj )
{
update_table( obj );
}
});
}
/* build table data */
function update_table( arr )
{
oTable1.fnClearTable();
for ( input in arr )
{
oTable1.fnAddData( [ arr[input] );
}
}
if you're doing a lot of this kind of thing you should consider using numpy
.
In [56]: import random, numpy
In [57]: lst = numpy.array([random.uniform(0, 5) for _ in range(1000)]) # example list
In [58]: a, b = 1, 3
In [59]: numpy.flatnonzero((lst > a) & (lst < b))[:10]
Out[59]: array([ 0, 12, 13, 15, 18, 19, 23, 24, 26, 29])
In response to Seanny123's question, I used this timing code:
import numpy, timeit, random
a, b = 1, 3
lst = numpy.array([random.uniform(0, 5) for _ in range(1000)])
def numpy_way():
numpy.flatnonzero((lst > 1) & (lst < 3))[:10]
def list_comprehension():
[e for e in lst if 1 < e < 3][:10]
print timeit.timeit(numpy_way)
print timeit.timeit(list_comprehension)
The numpy version is over 60 times faster.
In ASP.NET Core you could achieve this by adding 'asp-append-version':
<link rel="stylesheet" href="~/css/xxx.css" asp-append-version="true" />
<script src="~/js/xxx.js" asp-append-version="true"></script>
It will generate HTML:
<link rel="stylesheet" href="/css/xxx.css?v=rwgRWCjxemznsx7wgNx5PbMO1EictA4Dd0SjiW0S90g" />
The framework will generate a new version number every time you update the file.
You can instantiate 2 Node.js servers - one for HTTP and HTTPS
You can also define a setup function that both servers will execute, so that you don't have to write much duplicated code.
Here's the way I did it: (using restify.js, but should work for express.js, or node itself too)
http://qugstart.com/blog/node-js/node-js-restify-server-with-both-http-and-https/
I know this question is old, but the way I found the executable file for a similar application was to first open the application, then open Windows Task Manager, and in the "Processes" list right-click on it and choose "Open File Location".
I couldn't seem to find the location in the application reference file in my case...
Hilite doesn't seem to be mentioned yet in the answers, so: Hilite supports lots of languages (20+), can be used online also via API, and is on Github (so you can clone, modify, and run it on your own if you don't trust the online service). The online version can also be adjusted to one's needs via CSS rules.
I just found it some minutes ago since I needed a tool for copying xQuery into Word, but couldn't find a proper tool for doing so. The source program is baseX and for some reason, its formatting could not be transmitted to Word (also not via Keep format etc. when pasting). Also, many of the given answers are now, i.e. 06/2019, not working anymore or do not support xQuery. Hilite, however, did the job quite well.
Edit: a code block is not part of the result, unfortunatelly, just the highlighting. Nevertheless, it's better than nothing and adjusting the result by adding a block around is still less work than formating every single line by hand
BigInteger is immutable, you need to do this,
BigInteger sum = test.add(new BigInteger(30));
System.out.println(sum);
For me turning on and off the setting on
iOS Simulator -> Hardware -> Keyboard -> Connect Hardware Keyboard
proved to fix the issue on simulators.
Base on this I was able to solve this by changing the constructor of XmlSerializer
I was using instead of changing the classes.
Instead of using something like this (suggested in the other answers):
[XmlInclude(typeof(Derived))]
public class Base {}
public class Derived : Base {}
public void Serialize()
{
TextWriter writer = new StreamWriter(SchedulePath);
XmlSerializer xmlSerializer = new XmlSerializer(typeof(List<Derived>));
xmlSerializer.Serialize(writer, data);
writer.Close();
}
I did this:
public class Base {}
public class Derived : Base {}
public void Serialize()
{
TextWriter writer = new StreamWriter(SchedulePath);
XmlSerializer xmlSerializer = new XmlSerializer(typeof(List<Derived>), new[] { typeof(Derived) });
xmlSerializer.Serialize(writer, data);
writer.Close();
}
From the notebook menu you can save the file directly as a python script. Go to the 'File' option of the menu, then select 'Download as' and there you would see a 'Python (.py)' option.
Another option would be to use nbconvert from the command line:
jupyter nbconvert --to script 'my-notebook.ipynb'
Have a look here.
This should get you started:
R> qplot(hwy, cty, data = mpg) +
facet_grid(. ~ manufacturer) +
theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))
See also this question: How can I manipulate the strip text of facet plots in ggplot2?
in this case I start Outlook and then close it
Dim ol
Set ol = WScript.CreateObject("Outlook.Application") 'Starts Outlook
ol.quit 'Closes Outlook
I have tried everything but could not make it work. Finally I have used pyenv
and it worked directly like a charm.
So having homebrew
installed, juste do:
brew install pyenv
pyenv install 3.6.5
to manage virtualenvs:
brew install pyenv-virtualenv
pyenv virtualenv 3.6.5 env_name
See pyenv and pyenv-virtualenv for more info.
I have found using the pyenv-installer easier than homebrew to install pyenv and pyenv-virtualenv direclty:
curl https://pyenv.run | bash
To manage python version, either globally:
pyenv global 3.6.5
or locally in a given directory:
pyenv local 3.6.5
You need a public class for Form1 to initialize.
See this code:
namespace TimerApp
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private int counter = 60;
private void button1_Click(object sender, EventArgs e)
{
//Insert your code from before
}
private void timer1_Tick(object sender, EventArgs e)
{
//Again insert your code
}
}
}
I've tried this and it all worked fine
If you need anymore help feel free to comment :)
To hide an element, use:
display: none;
visibility: hidden;
To show an element, use:
display: block;
visibility: visible;
The difference is:
Visibility handles the visibility of the tag, the display
handles space it occupies on the page.
If you set the visibility
and do not change the display
, even if the tags are not seen, it still occupies space.
Logger log = Logger.getLogger("myApp");
log.setLevel(Level.ALL);
log.info("initializing - trying to load configuration file ...");
//Properties preferences = new Properties();
try {
//FileInputStream configFile = new //FileInputStream("/path/to/app.properties");
//preferences.load(configFile);
InputStream configFile = myApp.class.getResourceAsStream("app.properties");
LogManager.getLogManager().readConfiguration(configFile);
} catch (IOException ex)
{
System.out.println("WARNING: Could not open configuration file");
System.out.println("WARNING: Logging not configured (console output only)");
}
log.info("starting myApp");
this is working..:) you have to pass InputStream in readConfiguration().
A simple one liner that works can be done using:
[ "$#" -ne 1 ] && ( usage && exit 1 ) || main
This breaks down to:
Things to note:
@RequestBody MultiValueMap paramMap
in here Remove the @RequestBody Annotaion
@RequestMapping(value = "/signin",method = RequestMethod.POST)
public String createAccount(@RequestBody LogingData user){
logingService.save(user);
return "login";
}
@RequestMapping(value = "/signin",method = RequestMethod.POST)
public String createAccount( LogingData user){
logingService.save(user);
return "login";
}
like that
Remove the text decoration for the anchor tag
<a name="Section 1" style="text-decoration : none">Section</a>
the solution to your problem looks like this:
public class Category {
public long CategoryId { get; set; }
public string CategoryName { get; set; }
}
...
public class CategoryEqualityComparer : IEqualityComparer<Category>
{
public bool Equals(Category x, Category y)
=> x.CategoryId.Equals(y.CategoryId)
&& x.CategoryName .Equals(y.CategoryName,
StringComparison.OrdinalIgnoreCase);
public int GetHashCode(Mapping obj)
=> obj == null
? 0
: obj.CategoryId.GetHashCode()
^ obj.CategoryName.GetHashCode();
}
...
var distinctCategories = product
.Select(_ =>
new Category {
CategoryId = _.CategoryId,
CategoryName = _.CategoryName
})
.Distinct(new CategoryEqualityComparer())
.ToList();
<div ng-if="modeldate==''"><span ng-message="required" class="change">Date is required</span> </div>
you can use the ng-if directive as above.
(for fellow googlers)
If you are building a serious pipeline with the Build Flow Plugin, you can pass parameters between jobs with the DSL like this :
Supposing an available string parameter "CVS_TAG", in order to pass it to other jobs :
build("pipeline_begin", CVS_TAG: params['CVS_TAG'])
parallel (
// will be scheduled in parallel.
{ build("pipeline_static_analysis", CVS_TAG: params['CVS_TAG']) },
{ build("pipeline_nonreg", CVS_TAG: params['CVS_TAG']) }
)
// will be triggered after previous jobs complete
build("pipeline_end", CVS_TAG: params['CVS_TAG'])
Hint for displaying available variables / params :
// output values
out.println '------------------------------------'
out.println 'Triggered Parameters Map:'
out.println params
out.println '------------------------------------'
out.println 'Build Object Properties:'
build.properties.each { out.println "$it.key -> $it.value" }
out.println '------------------------------------'
Try '\1'
for the replacement (single quotes are important, otherwise you need to escape the \
):
"foo".gsub(/(o+)/, '\1\1\1')
#=> "foooooo"
But since you only seem to be interested in the capture group, note that you can index a string with a regex:
"foo"[/oo/]
#=> "oo"
"Z_123: foobar"[/^Z_.*(?=:)/]
#=> "Z_123"
Short answer
If running into this at home on a corporate machine, try again at work.
Details
I ran into this over the weekend. Pip and conda both broken, unable to install or update. SO was helpful, but many answers were problematic on a corporate machine - the solutions require the ability to pip install (already does not work) or require downloading an installer (the ones I wanted to download were prohibited by firewall settings).
What worked for me was to try again when I was on prem. This worked. It turned out the corporate firewall settings were different when using the machine at home vs at work.
If you assume just one result you could do this as in Edwin suggested by using specific users id.
$someUserId = 'abc123';
$stmt = $mysqli->prepare("SELECT ssfullname, ssemail FROM userss WHERE user_id = ?");
$stmt->bind_param('s', $someUserId);
$stmt->execute();
$stmt->bind_result($ssfullname, $ssemail);
$stmt->store_result();
$stmt->fetch();
ChromePhp::log($ssfullname, $ssemail); //log result in chrome if ChromePhp is used.
OR as "Your Common Sense" which selects just one user.
$stmt = $mysqli->prepare("SELECT ssfullname, ssemail FROM userss ORDER BY ssid LIMIT 1");
$stmt->execute();
$stmt->bind_result($ssfullname, $ssemail);
$stmt->store_result();
$stmt->fetch();
Nothing really different from the above except for PHP v.5
Wikipedia has this to say in the same context with a link to IEEE 754:
On a typical computer system, a 'double precision' (64-bit) binary floating-point number has a coefficient of 53 bits (one of which is implied), an exponent of 11 bits, and one sign bit.
2^53 is just over 9 * 10^15.
You have pointers and values:
int* p; // variable p is pointer to integer type
int i; // integer value
You turn a pointer into a value with *
:
int i2 = *p; // integer i2 is assigned with integer value that pointer p is pointing to
You turn a value into a pointer with &
:
int* p2 = &i; // pointer p2 will point to the address of integer i
Edit:
In the case of arrays, they are treated very much like pointers. If you think of them as pointers, you'll be using *
to get at the values inside of them as explained above, but there is also another, more common way using the []
operator:
int a[2]; // array of integers
int i = *a; // the value of the first element of a
int i2 = a[0]; // another way to get the first element
To get the second element:
int a[2]; // array
int i = *(a + 1); // the value of the second element
int i2 = a[1]; // the value of the second element
So the []
indexing operator is a special form of the *
operator, and it works like this:
a[i] == *(a + i); // these two statements are the same thing

AngularJS provides ngCookies module and $cookieStore service to use Browser Cookies.
We need to add angular-cookies.min.js file to use cookie feature.
Here is some method of AngularJS Cookie.
get(key); // This method returns the value of given cookie key.
getObject(key); //This method returns the deserialized value of given cookie key.
getAll(); //This method returns a key value object with all the cookies.
put(key, value, [options]); //This method sets a value for given cookie key.
remove(key, [options]); //This method remove given cookie.
Example
Html
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.1/angular.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.1/angular-cookies.min.js"></script>
</head>
<body ng-controller="MyController">
{{cookiesUserName}} loves {{cookietechnology}}.
</body>
</html>
JavaScript
var myApp = angular.module('myApp', ['ngCookies']);
myApp.controller('MyController', ['$scope', '$cookies', '$cookieStore', '$window', function($scope, $cookies, $cookieStore, $window) {
$cookies.userName = 'Max Joe';
$scope.cookiesUserName = $cookies.userName;
$cookieStore.put('technology', 'Web');
$scope.cookietechnology = $cookieStore.get('technology'); }]);
I have Taken reference from http://www.tutsway.com/simple-example-of-cookie-in-angular-js.php.
This will work everywhere.

Quick and dirty:

Probably not the best way to do it but it should work.
BTW: 259 = 16482-16224+1.
As of Feb 2018, fetch()
can be cancelled with the code below on Chrome (read Using Readable Streams to enable Firefox support). No error is thrown for catch()
to pick up, and this is a temporary solution until AbortController
is fully adopted.
fetch('YOUR_CUSTOM_URL')
.then(response => {
if (!response.body) {
console.warn("ReadableStream is not yet supported in this browser. See https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream")
return response;
}
// get reference to ReadableStream so we can cancel/abort this fetch request.
const responseReader = response.body.getReader();
startAbortSimulation(responseReader);
// Return a new Response object that implements a custom reader.
return new Response(new ReadableStream(new ReadableStreamConfig(responseReader)));
})
.then(response => response.blob())
.then(data => console.log('Download ended. Bytes downloaded:', data.size))
.catch(error => console.error('Error during fetch()', error))
// Here's an example of how to abort request once fetch() starts
function startAbortSimulation(responseReader) {
// abort fetch() after 50ms
setTimeout(function() {
console.log('aborting fetch()...');
responseReader.cancel()
.then(function() {
console.log('fetch() aborted');
})
},50)
}
// ReadableStream constructor requires custom implementation of start() method
function ReadableStreamConfig(reader) {
return {
start(controller) {
read();
function read() {
reader.read().then(({done,value}) => {
if (done) {
controller.close();
return;
}
controller.enqueue(value);

Anytime you have a question about a particular function in PHP, the easiest way to get quick answers is by visiting php.net, which has great documentation on all of the language's capabilities.
Looking up a function is easy, just visit http://php.net/<function name>
and it will forward you to the appropriate place. For the date function, we'll visit http://php.net/date.
We immediately learn a couple things about this function by examining its signature:
string date ( string $format [, int $timestamp = time() ] )
First, it returns a string. That's what the first string
in the above code means. Secondly, the first parameter is expected to be a string containing the format. There is an optional second parameter for passing in your own timestamp (to construct strings from some time other than now).
date("d-m-Y") // produces something like 03-12-2012
In this code, d
represents the day of the month (with a leading 0 is necessary). m
represents the month, again with a leading zero if necessary. And Y
represents the full 4-digit year. All of these are documented in the aforementioned link.
To satisfy your request of getting the hours, minutes, and seconds, we need to give a quick look at the documentation to see which characters represents those particular units of time. When we do that, we find the following:
h 12-hour format of an hour with leading zeros 01 through 12
i Minutes with leading zeros 00 to 59
s Seconds, with leading zeros 00 through 59
With this in mind, we can no create a new format string:
date("d-m-Y h:i:s"); // produces something like 03-12-2012 03:29:13
Hope this is helpful, and I hope you find the documentation has benefiting to your development as I have to mine.

You can't. Flexbox is not a grid system. It does not have the language constructs to do what you're asking for, at least not if you're using justify-content: space-between
. The closest you can get with Flexbox is to use the column orientation, which requires setting an explicit height:
http://cssdeck.com/labs/pvsn6t4z (note: prefixes not included)
ul {
display: flex;
flex-flow: column wrap;
align-content: space-between;
height: 4em;
}
However, it would be simpler to just use columns, which has better support and doesn't require setting a specific height:
http://cssdeck.com/labs/dwq3x6vr (note: prefixes not included)
ul {
columns: 15em;
}
Newer versions of JQuery mobile API (I guess its newer than 1.5) require adding 'back' button explicitly in header or bottom of each page.
So, try adding this in your page div tags:
data-add-back-btn="true"
data-back-btn-text="Back"
Example:
<div data-role="page" id="page2" data-add-back-btn="true" data-back-btn-text="Back">
Using this command you can find all partitions, size & free space: wmic logicaldisk get size, freespace, caption

Library functions like "pow" are usually carefully crafted to yield the minimum possible error (in generic case). This is usually achieved approximating functions with splines (according to Pascal's comment the most common implementation seems to be using Remez algorithm)
fundamentally the following operation:
pow(x,y);
has a inherent error of approximately the same magnitude as the error in any single multiplication or division.
While the following operation:
float a=someValue;
float b=a*a*a*a*a*a;
has a inherent error that is greater more than 5 times the error of a single multiplication or division (because you are combining 5 multiplications).
The compiler should be really carefull to the kind of optimization it is doing:
pow(a,6)
to a*a*a*a*a*a
it may improve performance, but drastically reduce the accuracy for floating point numbers.a*a*a*a*a*a
to pow(a,6)
it may actually reduce the accuracy because "a" was some special value that allows multiplication without error (a power of 2 or some small integer number)pow(a,6)
to (a*a*a)*(a*a*a)
or (a*a)*(a*a)*(a*a)
there still can be a loss of accuracy compared to pow
function.In general you know that for arbitrary floating point values "pow" has better accuracy than any function you could eventually write, but in some special cases multiple multiplications may have better accuracy and performance, it is up to the developer choosing what is more appropriate, eventually commenting the code so that noone else would "optimize" that code.
The only thing that make sense (personal opinion, and apparently a choice in GCC wichout any particular optimization or compiler flag) to optimize should be replacing "pow(a,2)" with "a*a". That would be the only sane thing a compiler vendor should do.

I would recommend to also look at the Thread Stack Size and see if you get more threads created. The default Thread Stack Size for JRockit 1.5/1.6 is 1 MB for 64-bit VM on Linux OS. 32K threads will require a significant amount of physical and virtual memory to honor this requirement.
Try to reduce the Stack Size to 512 KB as a starting point and see if it helps creating more threads for your application. I also recommend to explore horizontal scaling e.g. splitting your application processing across more physical or virtual machines.
When using a 64-bit VM, the true limit will depend on the OS physical and virtual memory availability and OS tuning parameters such as ulimitc. I also recommend the following article as a reference:
OutOfMemoryError: unable to create new native thread – Problem Demystified
Unset will destroy a particular session variable whereas session_destroy()
will destroy all the session data for that user.
It really depends on your application as to which one you should use. Just keep the above in mind.
unset($_SESSION['name']); // will delete just the name data
session_destroy(); // will delete ALL data associated with that user.
Simple way to compare time is :
$time = date('H:i:s',strtotime("11 PM"));
if($time < date('H:i:s')){
// your code
}
you can receive the session id by issuing the following regular expression on document.cookie:
alert(document.cookie.match(/PHPSESSID=[^;]+/));
in my example the cookie name to store session id is PHPSESSID (php server), just replace the PHPSESSID with the cookie name that holds the session id. (configurable by the web server)
Best way is to use the Carbon dependency.
With Carbon\Carbon::now();
you get the current Datetime.
With Carbon you can do like enything with the DateTime. Event things like this:
$tomorrow = Carbon::now()->addDay();
$lastWeek = Carbon::now()->subWeek();
I think the best way to do it is to create a global var array. Then do whatever you want to it inside the function data by passing it as a reference. No need to return anything too.
$array = array("white", "black", "yellow");
echo $array[0]; //this echo white
data($array);
function data(&$passArray){ //<<notice &
$passArray[0] = "orange";
}
echo $array[0]; //this now echo orange
I'm not quite sure if this question is still bothering you, since it has been several months. But I would like to share how I dealt with this. Here is the source code:

fragment.setArguments(args);
return fragment;
}

}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
Log.e("onCreateView","onCreateView");
if(FLAG!=12321){

The parentView
is the keypoint.
Normally, when onCreateView
, we just use return rootView
. But now, I add rootView to parentView
, and then return parentView
. To prevent "The specified child already has a parent. You must call removeView()
on the ..." error, we need to call parentView.removeView(rootView)
, or the method I supplied is useless.
I also would like to share how I found it. Firstly, I set up a boolean to indicate if the instance exists. When the instance exists, the rootView
will not be inflated again. But then, logcat gave the child already has a parent thing, so I decided to use another parent as a intermediate Parent View. That's how it works.
Hope it's helpful to you.
JQuery version:
$('yourInputSelectorHere').val("<script>alert('test');<\/script>")
$this->db->where('`id` IN (SELECT `someId` FROM `anotherTable` WHERE `someCondition`='condition')', NULL, FALSE);

The Rand() function will generate the same random number, if used in a table SELECT query. Same applies if you use a seed to the Rand function. An alternative way to do it, is using this:
SELECT ABS(CAST(CAST(NEWID() AS VARBINARY) AS INT)) AS [RandomNumber]
Got the information from here, which explains the problem very well.
yes Fragment.class
does not implement finish()
When working with fragments, instead of using this or refering to the context, always use getActivity()
. You should call
Here's the code snippet.I think it works.
Calendar cal = Calendar.getInstance();
SimpleDateFormat simpleMonth=new SimpleDateFormat("MMMM YYYY");
cal.add(Calendar.MONTH, -1);
System.out.println(simpleMonth.format(prevcal.getTime()));
This should work:
//iterate the array
for (int i = 0; i < theData.Length; i+=3)
{
//grab 3 items at a time and do db insert, continue until all items are gone. 'theData' will always be divisible by 3.
var a = theData[i];
var b = theData[i + 1];
var c = theData[i + 2];
}
I've been downvoted for this answer once. I'm pretty sure it is related to the use of theData.Length for the upperbound. The code as is works fine because array is guaranteed to be a multiple of three as the question states. If this guarantee wasn't in place, you would need to check the upper bound with theData.Length - 2 instead.
Here are some ways to get total records count while doing MongoDB Aggregation:
$count
:db.collection.aggregate([
// Other stages here
{ $count: "Total" }
])
For getting 1000 records this takes on average 2 ms and is the fastest way.
.toArray()
:db.collection.aggregate([...]).toArray().length
For getting 1000 records this takes on average 18 ms.
.itcount()
:db.collection.aggregate([...]).itcount()
For getting 1000 records this takes on average 14 ms.

This should be the code for a small prototype for the chatting app you wanted. Run both of them in separate terminals but then just check for the ports.
answer = True
myvar = "the answer is " + str(answer)
Python does not do implicit casting, as implicit casting can mask critical logic errors. Just cast answer to a string itself to get its string representation ("True"), or use string formatting like so:
myvar = "the answer is %s" % answer
Note that answer must be set to True
(capitalization is important).
The alignment-baseline
property is what you're looking for it can take the following values
auto | baseline | before-edge | text-before-edge |
middle | central | after-edge | text-after-edge |
ideographic | alphabetic | hanging | mathematical |
inherit
Description from w3c
This property specifies how an object is aligned with respect to its parent. This property specifies which baseline of this element is to be aligned with the corresponding baseline of the parent. For example, this allows alphabetic baselines in Roman text to stay aligned across font size changes. It defaults to the baseline with the same name as the computed value of the alignment-baseline property. That is, the position of "ideographic" alignment-point in the block-progression-direction is the position of the "ideographic" baseline in the baseline-table of the object being aligned.
Unfortunately, although this is the "correct" way of achieving what you're after it would appear Firefox have not implemented a lot of the presentation attributes for the SVG Text Module ('SVG in Firefox' MDN Documentation)
You could also use:
var latLon = L.latLng(40.737, -73.923);
var bounds = latLon.toBounds(500); // 500 = metres
map.panTo(latLon).fitBounds(bounds);
This will set the view level to fit the bounds in the map leaflet.
The select box arrow is a native ui element, it depends on the desktop theme or the web browser. Use a jQuery plugin (e.g. Select2, Chosen) or CSS.

If the C variant needs x hours less, then I'd invest that time in letting the algorithms run longer/again
"invest" isn't the right word here.
Build a working implementation in Python. You'll finish this long before you'd finish a C version.
Measure performance with the Python profiler. Fix any problems you find. Change data structures and algorithms as necessary to really do this properly. You'll finish this long before you finish the first version in C.
If it's still too slow, manually translate the well-designed and carefully constructed Python into C.
Because of the way hindsight works, doing the second version from existing Python (with existing unit tests, and with existing profiling data) will still be faster than trying to do the C code from scratch.

"Commercial use" in cases like this is actually just a shorthand to indicate that the product is dual-licensed under both an open source and a traditional paid-for commercial license.
Any "true" open source license will not discriminate against commercial use. (See clause 6 of the Open Source Definition.) However, open source licenses like the GPL contain clauses that are incompatible with most companies' approach to commercial software (since the GPL requires that you make your source code available if you incorporate GPL'ed code into your product).
Duel-licensing is a way to accommodate this and also provides a revenue stream for the company providing the software. For users that don't mind the restrictions of the GPL and don't need support, the product is available under an open source license. For users for whom the GPL's restrictions would be incompatible with their business model, and for users that do need support, a commercial license is available.
You gave the specific example of the Screwturn wiki, which is dual-licensed under the GPL and a commercial license. Under the terms of the GPL (i.e., without getting a "commercial" license), you can do the following:
In other words, there's a lot that you can do without getting a commercial license. This is especially true for web-based software, since people can use web-based software without it being distributed to them. Screwturn's web site even acknowledges this: they state that the commercial license is for "either integrating it in a commercial application, or using it in an enterprise environment where free software is not allowed," not for any use related to commerce.
All of the preceding is merely my understanding and is not intended to be legal advice. Consult your lawyer to be certain.
There is no "correct" way to store a 64-bit pointer in an 32-bit integer. The problem is not with casting, but with the target type loosing half of the pointer. The 32 remaining bits stored inside int
are insufficient to reconstruct a pointer to the thread function. Most answers just try to extract 32 useless bits out of the argument.
As Ferruccio said, int must be replaced with intptr_t
to make the program meaningful.
When you initialize unsigned int a to -1;
it means that you are storing the 2's
complement of -1
into the memory of a
.
Which is nothing but 0xffffffff
or 4294967295
.
Hence when you print it using %x or %u
format specifier you get that output.
By specifying signedness of a variable to decide on the minimum and maximum limit of value that can be stored.
Like with unsigned int
: the range is from 0 to 4,294,967,295
and int
: the range is from -2,147,483,648 to 2,147,483,647
For more info on signedness refer this

I had a similar error, My Class is
public class ServerInfo
{
public string Text { get; set; }
public string Value { get; set; }
public string PortNo { get; set; }
public override string ToString()
{
return Text;
}
}
But what I did, I casted my class to the SelectedItem property of the ComboBox. So, i'll have all of the class properties of the selected item.
// Code above
ServerInfo emailServer = (ServerInfo)cbServerName.SelectedItem;
mailClient.ServerName = emailServer.Value;
mailClient.ServerPort = emailServer.PortNo;
I hope this helps someone! Cheers!
I got this error, hope this will help someone:
const firstName = 'Joe';
const lastName = 'Blogs';
const wholeName = firstName + ' ' lastName + '.';
The problem was that I was missing a plus (+) between the empty space and lastName. This is a super simplified example: I was concatenating about 9 different parts so it was hard to spot the error.
Summa summarum: if you get "SyntaxError: missing ; before statement", don't look at what is wrong with the the semicolon (;) symbols in your code, look for an error in syntax on that line.
Use this
<xsl:text disable-output-escaping="yes">&</xsl:text>nbsp;
edit: Downvoters should probably validate that this works first (it does, and is the most general solution to the problem.)
You can include the branch to track when setting up remotes, to keep things working as you might expect:
git remote add --track master origin [email protected]:group/project.git # git
git remote add --track master origin [email protected]:group/project.git # git w/IP
git remote add --track master origin http://github.com/group/project.git # http
git remote add --track master origin http://172.16.1.100/group/project.git # http w/IP
git remote add --track master origin /Volumes/Git/group/project/ # local
git remote add --track master origin G:/group/project/ # local, Win
This keeps you from having to manually edit your git config or specify branch tracking manually.
Rather than browse the ouput of the :ls command and delete (unload, wipe..) a buffer by specifying its number, I find that using file names is often more effective.
For instance, after I opened a couple of .txt file to refresh my memories of some fine point.. copy and paste a few lines of text to use as a template of sorts.. etc. I would type the following:
:bd txt <Tab>
Note that the matching string does not have to be at the start of the file name.
The above displays the list of file names that match 'txt' at the bottom of the screen and keeps the :bd command I initially typed untouched, ready to be completed.
Here's an example:
doc1.txt doc2.txt
:bd txt
I could backspace over the 'txt' bit and type in the file name I wish to delete, but where this becomes really convenient is that I don't have to: if I hit the Tab key a second time, Vim automatically completes my command with the first match:
:bd doc1.txt
If I want to get rid of this particular buffer I just need to hit Enter.
And if the buffer I want to delete happens to be the second (third.. etc.) match, I only need to keep hitting the Tab key to make my :bd command cycle through the list of matches.
Naturally, this method can also be used to switch to a given buffer via such commands as :b.. :sb.. etc.
This approach is particularly useful when the 'hidden' Vim option is set, because the buffer list can quickly become quite large, covering several screens, and making it difficult to spot the particular buffer I am looking for.
To make the most of this feature, it's probably best to read the following Vim help file and tweak the behavior of Tab command-line completion accordingly so that it best suits your workflow:
:help wildmode
The behavior I described above results from the following setting, which I chose for consistency's sake in order to emulate bash completion:
:set wildmode=list:longest,full
As opposed to using buffer numbers, the merit of this approach is that I usually remember at least part of a given file name letting me target the buffer directly rather than having to first look up its number via the :ls command.
code bit should read:
var my_json;
$.getJSON(my_url, function(json) {
my_json = json;
});
import math as m
a=int(input("Enter the no"))
print(m.sqrt(a))
from math import sqrt
print(sqrt(25))
from math import sqrt as s
print(s(25))
from math import *
print(sqrt(25))
All works.
LG, VIZIO, SAMSUNG and PANASONIC TVs are not android based, and you cannot run APKs off of them... You should just buy a fire stick and call it a day. The only TVs that are android-based, and you can install APKs are: SONY, PHILIPS and SHARP.
#FACTS.
Since the indexing in ArrayList starts from 0 and ends one place before the actual size hence the correct statement to return the last arraylist element would be:
int last = mylist.get(mylist.size()-1);
For example:
if size of array list is 5, then size-1 = 4 would return the last array element.
If you have a Collection of stdClass objects, you could try with this:
$data = $data->map(function ($item){
return get_object_vars($item);
});
I have used it so far in two real projects very successfully. both are in the near real-time traffic information field (traffic as in cars on highways), distributed over several nodes, integrating messages between several parties, reliable backend systems. I'm not at liberty to give specifics on clients yet, when I do get the OK maybe it can be added as a reference.
Akka has really pulled through on those projects, even though we started when it was on version 0.7. (we are using scala by the way)
One of the big advantages is the ease at which you can compose a system out of actors and messages with almost no boilerplating, it scales extremely well without all the complexities of hand-rolled threading and you get asynchronous message passing between objects almost for free.
It is very good in modeling any type of asynchronous message handling. I would prefer to write any type of (web) services system in this style than any other style. (Have you ever tried to write an asynchronous web service (server side) with JAX-WS? that's a lot of plumbing). So I would say any system that does not want to hang on one of its components because everything is implicitly called using synchronous methods, and that one component is locking on something. It is very stable and the let-it-crash + supervisor solution to failure really works well. Everything is easy to setup programmatically and not hard to unit test.
Then there are the excellent add-on modules. The Camel module really plugs in well into Akka and enables such easy development of asynchronous services with configurable endpoints.
I'm very happy with the framework and it is becoming a defacto standard for the connected systems that we build.

Well, I simply could not find this (for me) mythical "Use dynamic ports" option. I have post screenshots.
On a more constructive note, I believe that the port numbers are to be found in the solution file AND CRUCIALLY cross referenced against the IIS Express config file
C:\Users\<username>\Documents\IISExpress\config\applicationhost.config
I tried editing the port number in just the solution file but strange things happened. I propose (no time yet) that it needs a consistent edit across both the solution file and the config file.
I'm assuming you want the two boxes in the sidebar to be next to each other horizontally, so something like this fiddle? That uses inline-block
, or you could achieve the same thing by floating the boxes.
EDIT - I've amended the above fiddle to do what I think you want, though your question could really do with being clearer. Similar to @balexandre's answer, though I've used :nth-child(odd)
instead. Both will work, or if support for older browsers is important you'll have to stick with another helper class.

See my question: What is the best subversion client for Linux?
I also agree, GUI clients in linux suck.
I use subeclipse in Eclipse and RapidSVN in gnome.
The problem is that you're trying to print an unicode character to a possibly non-unicode terminal. You need to encode it with the 'replace
option before printing it, e.g. print ch.encode(sys.stdout.encoding, 'replace')
.
Accessing the fields directly is not really good style in java. I would suggest creating getter and setter methods for the fields of your bean and then using then Introspector and BeanInfo classes from the java.beans package.
MyBean bean = new MyBean();
BeanInfo beanInfo = Introspector.getBeanInfo(MyBean.class);
for (PropertyDescriptor propertyDesc : beanInfo.getPropertyDescriptors()) {
String propertyName = propertyDesc.getName();
Object value = propertyDesc.getReadMethod().invoke(bean);
}
Maybe I read the problem wrong, but I believe you already have inserted the course 11 records and simply need to update those that meet the criteria you listed with course 6's data.
If this is the case, you'll want to use an UPDATE
...FROM
statement:
UPDATE MyTable
SET
complete = 1,
complete_date = newdata.complete_date,
post_score = newdata.post_score
FROM
(
SELECT
userID,
complete_date,
post_score
FROM MyTable
WHERE
courseID = 6
AND complete = 1
AND complete_date > '8/1/2008'
) newdata
WHERE
CourseID = 11
AND userID = newdata.userID
I have a solution for this. First thing that add is already having a string value as input() function by default takes the input as string. Second thing that you can use append method to append value of add variable in your list.
Please do check my code I have done some modification : - {1} You can enter command in capital or small or mix {2} If user entered wrong command then your program will ask to input command again
inventory = ["sword","potion","armour","bow"] print(inventory) print("\ncommands : use (remove item) and pickup (add item)") selection=input("choose a command [use/pickup] : ") while True: if selection.lower()=="use": print(inventory) remove_item=input("What do you want to use? ") inventory.remove(remove_item) print(inventory) break
elif selection.lower()=="pickup":
print(inventory)
add_item=input("What do you want to pickup? ")
inventory.append(add_item)
print(inventory)
break
else:
print("Invalid Command. Please check your input")
selection=input("Once again choose a command [use/pickup] : ")
You can just use: $("#msform").hide()
. This sets the element to display: none
As others have also mentioned, this can be readily solved by adding the following to the onCreate() of the Activity:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
getWindow().setStatusBarColor(ContextCompat.getColor(this, R.color.primary_dark));
}
However, the important point I want to add here is that in some cases, even the above does not change the status bar color. For example, when using MikePenz library for Navigation Drawer, it implicityly overrides the status bar color, so that you need to manually add the following for it to work:
.withStatusBarColorRes(R.color.status_bar_color)
My two cents for beginners: in above samples someone changes coordinates, other uses "autoresizing mask", and other constraints:
As Apple says, do not mix these 3 types of logic. If You have constraints in Storyboard, do not try to change x/y. It definitively not work.
To serialize the response into a class, define the target class
public class Result {
public Long user_id;
}
And map response to it:
Response response = given().body(requestBody).when().post("/admin");
Result result = response.as(Result.class);
You must have Jackson or Gson in the classpath as the documentation states: http://rest-assured.googlecode.com/svn/tags/2.3.1/apidocs/com/jayway/restassured/response/ResponseBodyExtractionOptions.html#as(java.lang.Class)
You can check the existence of a symlink and that it is not broken with:
[ -L ${my_link} ] && [ -e ${my_link} ]
So, the complete solution is:
if [ -L ${my_link} ] ; then
if [ -e ${my_link} ] ; then
echo "Good link"
else
echo "Broken link"
fi
elif [ -e ${my_link} ] ; then
echo "Not a link"
else
echo "Missing"
fi
-L
tests whether there is a symlink, broken or not. By combining with -e
you can test whether the link is valid (links to a directory or file), not just whether it exists.

This error popped in front of me when I tried to manually change .jpg file to .png and then was copying & pasting it in my 'drawable' folder.
I rebuild and cleaned Project many times but nothing happened, then I removed that .png image and replaced that file with a different pre-existing .png image (or you can change it by help of paint and then paste it in drawable folder)
Now rebuild and clean the project . It works.
Hope it helps..!
Make sure the physical available memory is more then VM defined min/max memory.
There are a couple of commonly quoted solutions to this problem. Unfortunately neither of these are entirely satisfactory:
But then there's reflection. Is there anything you can't do using reflection?
private static void removeCryptographyRestrictions() {
if (!isRestrictedCryptography()) {
logger.fine("Cryptography restrictions removal not needed");
return;
}
try {
/*
* Do the following, but with reflection to bypass access checks:
*
* JceSecurity.isRestricted = false;
* JceSecurity.defaultPolicy.perms.clear();
* JceSecurity.defaultPolicy.add(CryptoAllPermission.INSTANCE);
*/
final Class<?> jceSecurity = Class.forName("javax.crypto.JceSecurity");
final Class<?> cryptoPermissions = Class.forName("javax.crypto.CryptoPermissions");
final Class<?> cryptoAllPermission = Class.forName("javax.crypto.CryptoAllPermission");
final Field isRestrictedField = jceSecurity.getDeclaredField("isRestricted");
isRestrictedField.setAccessible(true);
final Field modifiersField = Field.class.getDeclaredField("modifiers");
modifiersField.setAccessible(true);
modifiersField.setInt(isRestrictedField, isRestrictedField.getModifiers() & ~Modifier.FINAL);
isRestrictedField.set(null, false);
final Field defaultPolicyField = jceSecurity.getDeclaredField("defaultPolicy");
defaultPolicyField.setAccessible(true);
final PermissionCollection defaultPolicy = (PermissionCollection) defaultPolicyField.get(null);
final Field perms = cryptoPermissions.getDeclaredField("perms");
perms.setAccessible(true);
((Map<?, ?>) perms.get(defaultPolicy)).clear();
final Field instance = cryptoAllPermission.getDeclaredField("INSTANCE");
instance.setAccessible(true);
defaultPolicy.add((Permission) instance.get(null));
logger.fine("Successfully removed cryptography restrictions");
} catch (final Exception e) {
logger.log(Level.WARNING, "Failed to remove cryptography restrictions", e);
}
}
private static boolean isRestrictedCryptography() {
// This matches Oracle Java 7 and 8, but not Java 9 or OpenJDK.
final String name = System.getProperty("java.runtime.name");
final String ver = System.getProperty("java.version");
return name != null && name.equals("Java(TM) SE Runtime Environment")
&& ver != null && (ver.startsWith("1.7") || ver.startsWith("1.8"));
}
Simply call removeCryptographyRestrictions()
from a static initializer or such before performing any cryptographic operations.
The JceSecurity.isRestricted = false
part is all that is needed to use 256-bit ciphers directly; however, without the two other operations, Cipher.getMaxAllowedKeyLength()
will still keep reporting 128, and 256-bit TLS cipher suites won't work.
This code works on Oracle Java 7 and 8, and automatically skips the process on Java 9 and OpenJDK where it's not needed. Being an ugly hack after all, it likely doesn't work on other vendors' VMs.
It also doesn't work on Oracle Java 6, because the private JCE classes are obfuscated there. The obfuscation does not change from version to version though, so it is still technically possible to support Java 6.
There's a static method in ToolStripRenderer
class, named CreateDisabledImage
.
Its usage is as simple as:
Bitmap c = new Bitmap("filename");
Image d = ToolStripRenderer.CreateDisabledImage(c);
It uses a little bit different matrix than the one in the accepted answer and additionally multiplies it by a transparency of value 0.7, so the effect is slightly different than just grayscale, but if you want to just get your image grayed, it's the simplest and best solution.
Use boolean
rather than Boolean
every time you can. This will avoid many NullPointerException
s and make your code more robust.
Boolean
is useful, for example
MessageFormat.format()
.You could try writing the XDocument to an XmlWriter piped to an XmlReader for an XmlDocument.
If I understand the concepts properly, a direct conversion is not possible (the internal structure is different / simplified with XDocument). But then, I might be wrong...
When an array is passed to a method or function in PHP, it is passed by value unless you explicitly pass it by reference, like so:
function test(&$array) {
$array['new'] = 'hey';
}
$a = $array(1,2,3);
// prints [0=>1,1=>2,2=>3]
var_dump($a);
test($a);
// prints [0=>1,1=>2,2=>3,'new'=>'hey']
var_dump($a);
In your second question, $b
is not a reference to $a
, but a copy of $a
.
Much like the first example, you can reference $a
by doing the following:
$a = array(1,2,3);
$b = &$a;
// prints [0=>1,1=>2,2=>3]
var_dump($b);
$b['new'] = 'hey';
// prints [0=>1,1=>2,2=>3,'new'=>'hey']
var_dump($a);
My recommendation? Don't use jQuery at all. I had the same problem as you. I found that $('#my_input').val()
always return some weird result.
Try to use document.getElementById('my_input').valueAsNumber
instead of $("#my_input").val();
and then, use Number(your_value_retrieved)
to try to create a Number. If the value is NaN, you know certainly that that's not a number.
One thing to add is when you write a number on the input, the input will actually accept almost any character (I can write the euro sign, a dollar, and all of other special characters), so it is best to retrieve the value using .valueAsNumber
instead of using jQuery.
Oh, and BTW, that allows your users to add internationalization (i.e.: support commas instead of dots to create decimal numbers). Just let the Number()
object to create something for you and it will be decimal-safe, so to speak.
You can't do this 100% accurately with JavaScript alone.

1) Start by opening up git-bash.exe in Administrator mode. (Right click the file and select "Run as Administrator", or change settings in Properties → Compatibility → Run this program as administrator.)
2) Run cd ~
. It will take you to C:/Users/<Your-Username>
.
3) Run vi .bashrc
. This will open you up into the editor. Hit INSERT and then start entering the following info:
alias ll="ls -la" # this changes the default ll on git bash to see hidden files.
cd "C:\directory\to\your\work\path\"
ll # this shows your your directory before you even type anything.
Setting the android:scrollbarFadeDuration="0"

This is how I fixed this issue on Windows 10:
My JDK is located in C:\Program Files\Java\jdk-11.0.2
and the problem I had was the space in Program Files
. If I set JAVA_HOME using set JAVA_HOME="C:\Program Files\Java\jdk-11.0.2"
then Maven had an issue with the double quotes:
C:\Users>set JAVA_HOME="C:\Program Files\Java\jdk-11.0.2"
C:\Users>echo %JAVA_HOME%
"C:\Program Files\Java\jdk-11.0.2"
C:\Users>mvn -version
Files\Java\jdk-11.0.2""=="" was unexpected at this time.
Referring to Program Files
as PROGRA~1
didn't help either. The solution is using the PROGRAMFILES variable inside of JAVA_HOME:
C:\Users>echo %PROGRAMFILES%
C:\Program Files
C:\Program Files>set JAVA_HOME=%PROGRAMFILES%\Java\jdk-11.0.2
C:\Program Files>echo %JAVA_HOME%
C:\Program Files\Java\jdk-11.0.2
C:\Program Files>mvn -version

I wanted to make a simple and understandable example
if you call a method like this, your client will not know return type
var interestPoints = Mediator.Handle(new InterestPointTypeRequest
{
LanguageCode = request.LanguageCode,
AgentId = request.AgentId,
InterestPointId = request.InterestPointId,
});
Then you should say to compiler i know the return type is List<InterestPointTypeMap>
var interestPoints = Mediator.Handle<List<InterestPointTypeMap>>(new InterestPointTypeRequest
{
LanguageCode = request.LanguageCode,
AgentId = request.AgentId,
InterestPointId = request.InterestPointId,
InterestPointTypeId = request.InterestPointTypeId
});
the compiler will no longer be mad at you for knowing the return type
I just want to provide some other people with help with a more serious variant of this problem. In some situations, the error ("Row size too large .. Changing some columns to TEXT or BLOB") will occur even with "alter table drop column" and "alter table modify column" statements!
Consequently you can become completely stuck, not able to change a varchar to a text, or drop columns (trying to solve the problem ironically results in the same message).
If you have this problem, the solution is to alter or drop multiple columns at once. You can do this in MySQL with the syntax "alter table example drop column a, drop column b, drop column c" and if you drop enough columns at once, it will actually execute rather than raising the error.
And it's unlikely too -- EOT is a fairly restrictive format that is supported only by IE. Both Safari 3.1 and Firefox 3.1 (well the current alpha) and possibly Opera 9.6 support true type font (ttf) embedding, and at least Safari supports SVG fonts through the same mechanism. A list apart had a good discussion about this a while back.
Above answers are in python2. So for python 3 users I am giving this answer. You can use the bellow code:
import pandas as pd
fields = ['star_name', 'ra']
df = pd.read_csv('data.csv', skipinitialspace=True, usecols=fields)
# See the keys
print(df.keys())
# See content in 'star_name'
print(df.star_name)
#import <QuickLook/QuickLook.h>
#import "ViewController.h"
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
QLPreviewController *preview = [[QLPreviewController alloc] init];
preview.dataSource = self;
[self addChildViewController:preview];
[self.view addSubview:preview.view];
}
#pragma mark - QLPreviewControllerDataSource
- (NSInteger)numberOfPreviewItemsInPreviewController:(QLPreviewController *)previewController
{
return 1;
}
- (id)previewController:(QLPreviewController *)previewController previewItemAtIndex:(NSInteger)idx
{
NSURL *fileURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"myanimated.gif" ofType:nil]];
return fileURL;
}
@end
I guess you could use curl
and wget
, but since Oracle requires you to check of some checkmarks this will be painfull to emulate with the tools mentioned. You would have to download the page with the license agreement and from looking at it figure out what request is needed to get to the actual download.
Of course you could simply start a browser, but this might not qualify as 'from the command line'. So you might want to look into lynx
, a text based browser.
